Exhibit (a)(1)(A)

Offer to Purchase for Cash

by

RIVIERA RESOURCES, INC.

of

Up to 2,666,666 Shares of its Common Stock

at a Purchase Price of $15.00 Per Share

Riviera Resources, Inc., a Delaware corporation (the “Company,” “we,” or “us”), is offering to purchase up to 2,666,666 shares of its common stock, par value $0.01 per share (the “common stock”), at a price of $15.00 per share without interest, upon the terms and subject to the conditions of this Offer to Purchase and the related Letter of Transmittal and the other materials filed as exhibits to the Issuer Tender Offer on Schedule TO-I (which together, as they may be amended and supplemented from time to time, constitute the “Offer”). Unless the context otherwise requires, all references to the “shares” shall refer to the common stock of the Company.

On the terms and subject to the conditions of the Offer, we will pay for shares properly tendered and not properly withdrawn in the Offer, a price of $15.00 per share, less any applicable withholding taxes and without interest. Only shares properly tendered and not properly withdrawn will be purchased. Due to the proration and conditional tender offer provisions described in this Offer to Purchase, all of the shares tendered may not be purchased if more than the number of shares we seek are properly tendered. Shares tendered but not purchased in the Offer will be returned at our expense promptly following the expiration of the Offer. See Section 3.

Subject to certain limitations and legal requirements, we reserve the right, in our sole discretion, to purchase more than 2,666,666 shares pursuant to the Offer. See Section 1.

The Offer is not conditioned on any minimum number of shares being tendered. However, the Offer is subject to certain other conditions. See Section 7.

The shares are listed and traded on the OTC Markets (“OTCQX”) under the symbol “RVRA.” We announced our intention to make the Offer after the market closed on June 13, 2019. On June 13, 2019, the last trading day before that announcement, the OTCQX closing price per share of our common stock was $12.00. On June 17, 2019, the last full trading day before commencement of the Offer, the OTCQX closing price per share of our common stock was $12.48. The $15.00 purchase price per share in the Offer represents a premium of approximately 20.2% to the OTCQX closing price per share on June 17, 2019. Stockholders are urged to obtain current market quotations for the shares. See Section 8.

Our Board of Directors has approved making the Offer. However, neither we nor our Board of Directors, the Dealer Manager, the Information Agent or the Depositary makes any recommendation to you as to whether to tender or refrain from tendering your shares and we have not authorized any person to make any such recommendation. You must decide whether to tender your shares and, if so, how many shares to tender. In doing so, you should read and evaluate carefully the information in, or incorporated by reference in, this Offer to Purchase and in the related Letter of Transmittal, including our reasons for making the Offer, and should discuss whether to tender any of your shares with your broker or other financial or tax advisor. See Section 2.

The Company’s directors, executive officers and affiliates and certain funds which are affiliated with certain members of our Board of Directors are entitled to participate in the Offer on the same basis as all other stockholders. We do not know whether or to what extent such parties will participate in the Offer.

Neither the Securities and Exchange Commission (the “Commission”) nor any state securities commission has approved or disapproved of this transaction or passed upon the merits or fairness of such transaction or passed upon the adequacy or accuracy of the information contained in this document. Any representation to the contrary is a criminal offense.

The Dealer Manager for the Offer is:

Citigroup

June 18, 2019

IMPORTANT

If you desire to tender all or any portion of your shares, you should either (1)(a) complete and sign the Letter of Transmittal in accordance with the instructions to the Letter of Transmittal, have your signature thereon guaranteed if Instruction 1 to the Letter of Transmittal so requires, mail or deliver the Letter of Transmittal, together with any other required documents, including the share certificates, to the Depositary (as defined herein) or (b) tender the shares in accordance with the procedure for book-entry transfer set forth in Section 3, or (2) request that your bank, broker, dealer, trust company or other nominee effect the transaction for you. If you have shares registered in the name of a bank, broker, dealer, trust company or other nominee, you must contact that institution if you desire to tender those shares. Beneficial owners should be aware that their broker, dealer, commercial bank, trust company or other nominee may establish its own earlier deadline for participation in the Offer. Accordingly, beneficial owners wishing to participate in the Offer should contact their broker, dealer, commercial bank, trust company or other nominee as soon as possible in order to determine the times by which such owner must take action in order to participate in the Offer.

If you desire to tender shares and your certificates for those shares are not immediately available or the procedure for book-entry transfer cannot be completed on a timely basis, or time will not permit all required documents to reach the Depositary prior to the Expiration Time, your tender may be effected by following the procedure for guaranteed delivery set forth in Section 3.

To properly tender shares, you must validly complete the Letter of Transmittal.

Questions and requests for assistance may be directed to D.F. King & Co., Inc., the information agent for the Offer (the “Information Agent”), or Citigroup Global Markets Inc., the dealer manager for the Offer (the “Dealer Manager”), at their respective addresses and telephone numbers set forth on the back cover page of this document. Requests for additional copies of this document, the related Letter of Transmittal or the Notice of Guaranteed Delivery may be directed to the Information Agent.

We are not making the Offer to, and will not accept any tendered shares from, stockholders in any U.S. state where it would be illegal to do so. However, we may, at our discretion, take any actions necessary for us to make this Offer to stockholders in any such U.S. state.

None of us, the Dealer Manager, the Information Agent or the Depositary has authorized any person to make any recommendation as to whether you should tender or refrain from tendering your shares in the Offer. None of us, the Dealer Manager, the Information Agent or the Depositary has authorized anyone to provide you with information or to make any representation in connection with the Offer other than those contained, or incorporated by reference, in this Offer to Purchase, the related Letter of Transmittal and the other materials filed as exhibits to the Issuer Tender Offer Statement on Schedule TO-I. We take no responsibility for, and can provide no assurance as to the reliability of, any information or representation, recommendation or information that others may provide you.

TABLE OF CONTENTS

SUMMARY TERM SHEET

We are providing this summary term sheet for your convenience. This summary term sheet highlights certain material information in the remainder of this Offer to Purchase, but you should realize that it does not describe all of the details of the Offer to the same extent described in the remainder of this Offer to Purchase. We urge you to read the entire Offer to Purchase and the related Letter of Transmittal because they contain the full details of the Offer. We have included references to the sections of this document where you will find a more complete discussion.

Who is offering to purchase my shares?

The Company is offering to purchase up to 2,666,666 shares of its common stock, par value $0.01 per share. See Section 1.

What will the purchase price for the shares be and what will be the form of payment?

The purchase price for the shares will be $15.00 per share. If your shares are purchased in the Offer, we will pay you the purchase price, in cash, less any applicable withholding taxes and without interest, promptly after the expiration of the Offer. See Sections 1 and 5.

How many shares will the Company purchase in the Offer?

We will purchase up to 2,666,666 shares in the Offer (representing approximately 4.2% of our outstanding shares), or if a lesser number of shares are properly tendered, all shares that are properly tendered and not properly withdrawn. If more than 2,666,666 shares are properly tendered, we will purchase all shares properly tendered on a pro rata basis, except for conditional tenders whose condition was not met, which we will not purchase (except as described in Section 6). We also expressly reserve the right to purchase additional shares, up to 2% of our outstanding shares (approximately 1.3 million shares, based on 63,621,542 shares of our common stock issued and outstanding as of June 14, 2019), without extending the Offer, and could decide to purchase more shares, subject to applicable legal requirements. See Sections 1 and 7.

How will the Company pay for the shares?

Assuming that the maximum of 2,666,666 shares to be purchased are tendered in the Offer at a price of $15.00 per share, the aggregate purchase price will be approximately $40 million. We anticipate that we will pay for the shares purchased in the Offer and all fees and expenses applicable to the Offer from cash on hand. As of June 15, 2019, we had approximately $74.6 million in cash and cash equivalents. The Offer is not separately conditioned upon the receipt of financing. See Section 9.

How long do I have to tender my shares? Can the Offer be extended, amended or terminated?

You may tender your shares until the Offer expires. The Offer will expire on Tuesday, July 16, 2019 at 11:59 p.m., New York City time, unless we extend it. See Section 1. If a broker, dealer, commercial bank, trust company or other nominee holds your shares, it is likely they have an earlier deadline for administrative reasons, such as four business days before the expiration of the Offer (e.g., 5:00 p.m., New York City time, on Wednesday, July 10, 2019), for you to act to instruct them to accept the Offer on your behalf. We urge you to contact the broker, dealer, commercial bank, trust company or other nominee to find out their deadline. See Section 3.

We may choose to extend the Offer at any time and for any reason, subject to applicable laws. See Section 15. We cannot assure you that we will extend the Offer or indicate the length of any extension that we may provide. If we extend the Offer, we will delay the acceptance of any shares that have been tendered. We can also amend the Offer in our sole discretion or terminate the Offer under certain circumstances. See Sections 7 and 15.

i

How will I be notified if the Company extends the Offer or amends the terms of the Offer?

If we extend the Offer, we will issue a press release announcing the extension and the new Expiration Time by 9:00 a.m., New York City time, on the business day after the previously scheduled Expiration Time. We will announce any amendment to the Offer by making a public announcement of the amendment. See Section 15.

What is the purpose of the Offer?

Our Board of Directors, after evaluating the expected capital requirements of our operations and other expected cash commitments, believes that purchasing shares of our common stock in the Offer represents a prudent use of the funds required for the Offer given our business profile, assets and current market price. As of June 15, 2019, we had approximately $74.6 million in cash and cash equivalents. Assuming that the maximum of 2,666,666 shares to be purchased are tendered in the Offer at a price of $15.00 per share, the aggregate purchase price will be approximately $40 million. We will use a portion of cash on hand to fund the Offer.

The Offer represents an opportunity for us to return capital to our stockholders who elect to tender their shares, subject to the terms and conditions of the Offer. Additionally, stockholders who do not participate in the Offer will automatically increase their relative percentage interest in us and our future operations at no additional cost to them. The Offer also provides stockholders with an opportunity to obtain liquidity with respect to all or a portion of their shares, without potential disruption to the share price and the usual transaction costs associated with market sales. See Section 2.

What are the significant conditions to the Offer?

Our obligation to accept and pay for your tendered shares depends upon a number of conditions that must be satisfied or waived prior to the Expiration Time, including, but not limited to:

The Offer is subject to a number of other conditions described in greater detail in Section 7.

ii

Following the Offer, will the Company continue as a public company?

Yes. The completion of the Offer in accordance with its terms and conditions will not cause the Company to stop being subject to the periodic reporting requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We also do not expect the Offer to cause our common stock to cease to be traded on the OTCQX. As of June 14, 2019, we had 16 holders of record of common stock based on information provided by our transfer agent and by the Depository Trust & Clearing Corporation (“DTC”).

How do I tender my shares?

If you want to tender all or part of your shares, you must do one of the following before 11:59 p.m., New York City time, on Tuesday, July 16, 2019, or any later time and date to which the Offer may be extended:

You may contact the Dealer Manager, the Information Agent or your broker for assistance. The contact information for the Dealer Manager and the Information Agent appears on the back cover of this Offer to Purchase. See Section 3 and the Instructions to the Letter of Transmittal.

May holders of restricted stock unit awards participate in the Offer?

Holders of restricted stock unit awards may not tender such restricted stock units in the Offer unless and until the underlying shares have vested and the restrictions on such awards have lapsed. See Section 3.

Do the Company’s directors or executive officers or affiliates intend to tender their shares in the Offer?

The Company’s directors, executive officers and affiliates are entitled to participate in the Offer on the same basis as all other stockholders. We do not know whether or to what extent our directors or executive officers will participate in the Offer. In addition, certain funds affiliated with Fir Tree Capital Management LP, Elliott Associates, L.P., York Capital Management, L.P. and P. Schoenfeld Asset Management LP, which are affiliated with certain members of the Company’s Board of Directors (the “Affiliated Holders”) are also entitled to participate in the Offer on the same basis as all other stockholders. We do not know whether or to what extent the Affiliated Holders will participate in the Offer. The Affiliated Holders collectively held 40,518,819 shares, or approximately 63.7% of the issued and outstanding common stock as of June 14, 2019.

Our directors, executive officers and affiliates (including the Affiliated Holders) may, subject to applicable law and applicable policies of the Company, sell their shares from time to time in open-market and/or other transactions at prices that may be more or less favorable than the purchase price to be paid to our stockholders pursuant to the Offer. If no such transactions by our directors, executive officers and affiliates occur, the beneficial ownership of our directors, executive officers and affiliates will increase as a percentage of our outstanding common stock following the consummation of the Offer. See Section 11.

iii

What happens if more than 2,666,666 shares are tendered?

If the terms and conditions of the Offer have been satisfied or waived and more than 2,666,666 shares (or such greater number of shares as we may elect to purchase, subject to applicable law) are properly tendered and not properly withdrawn on or prior to the Expiration Time, we will purchase shares:

Because of the proration and conditional tender provisions described above, we may not purchase all of the shares that you tender. See Section 1.

How will the tender offer affect the number of our shares outstanding and the number of record holders?

As of June 14, 2019, we had 63,621,542 shares of common stock outstanding. If the conditions to the Offer are satisfied or waived and the Offer is fully subscribed, we will have 60,954,876 shares outstanding immediately following the purchase of shares tendered in the Offer (based on the number of shares outstanding as of June 14, 2019). The actual number of shares outstanding immediately following completion of the Offer will depend on the number of shares tendered and purchased in the Offer. See Section 2. In addition, if more than 2,666,666 shares are tendered in the Offer, we reserve the right to accept for purchase pursuant to the Offer up to an additional 2% of our outstanding shares without extending the Offer. We also expressly reserve the right, in our sole discretion, to purchase additional shares subject to applicable legal and regulatory requirements. See Section 1.

Furthermore, if any of our stockholders (i) who hold shares in their own name as holders of record or (ii) who are “registered holders” as participants in the DTC’s system whose names appear on a security position listing, tender their shares in full and that tender is accepted in full, then the number of our record holders would be reduced. See Section 2.

Stockholders who do not have their shares purchased in the Offer will realize a proportionate increase in their relative ownership interest in the Company following the purchase of shares pursuant to the Offer. See Section 2.

If I own fewer than 100 shares and I tender some or all of my shares, will I be subject to proration?

Yes. If you own beneficially or of record fewer than 100 shares in the aggregate, any shares you tender will be subject to the same terms and conditions of the Offer, including the proration provisions, as all other tenders pursuant to the Offer.

Once I have tendered shares in the Offer, can I withdraw my tender?

Yes. You may withdraw any shares you have tendered at any time before 11:59 p.m., New York City time, on Tuesday, July 16, 2019, unless we extend the Offer, in which case you can withdraw your shares until the expiration of the Offer as extended. If we have not accepted for payment the shares you have tendered to us, you may also withdraw your shares at any time after 11:59 p.m., New York City time, on Tuesday, August 13, 2019, the 40^th business day after the commencement of the Offer. See Section 4.

iv

How do I withdraw shares I previously tendered?

To withdraw shares, you must deliver a written notice of withdrawal with the required information to the Depositary during the time period in which you still have the right to withdraw the shares. Your notice of withdrawal must specify your name, the number of shares to be withdrawn and the name of the registered holder of these shares. Some additional requirements apply if the share certificates to be withdrawn have been delivered to the Depositary or if your shares have been tendered under the procedure for book-entry transfer set forth in Section 3. See Section 4. If you have tendered your shares by giving instructions to a bank, broker, dealer, trust company or other nominee, you must instruct that person to arrange for the withdrawal of your shares.

Has the Company or its Board of Directors adopted a position on the Offer?

Our Board of Directors has approved making the Offer. However, neither we nor our Board of Directors, the Dealer Manager, the Information Agent or the Depositary makes any recommendation to you as to whether you should tender or refrain from tendering your shares. You must make your own decision as to whether to tender your shares and, if so, how many shares to tender. In so doing, you should read carefully the information in this Offer to Purchase and in the related Letter of Transmittal, including our reasons for making the Offer. All of our directors and executive officers have advised us that they will not tender shares pursuant to the Offer. You are urged to discuss your decisions with your own tax advisor, financial advisor and/or broker.

If I decide not to tender, how will the Offer affect my shares?

Stockholders who choose not to tender their shares will own a greater percentage interest in our outstanding common stock following the consummation of the Offer if shares are purchased in the Offer. See Section 2.

What is the recent market price of my shares?

We announced our intention to make the Offer after the market closed on June 13, 2019. On June 13, 2019, the last full trading day before that announcement, the OTCQX closing price per share of our common stock was $12.00. On June 17, 2019, the last full trading day before commencement of the Offer, the OTCQX closing price per share of our common stock was $12.48. The $15.00 purchase price per share in the Offer represents a premium of approximately 20.2% to the OTCQX closing price per share on June 17, 2019. We urge you to obtain current market quotations for the shares before deciding whether to tender any of your shares. See Section 8.

When will the Company pay for the shares I tender?

We will pay the purchase price, less any applicable withholding taxes and without interest, for the shares we purchase promptly after the expiration of the Offer and the acceptance of the shares for payment. We will announce the final proration factor and commence payment for any shares purchased pursuant to the tender offer promptly after the expiration of the Offer. See Section 5.

Will I have to pay brokerage commissions if I tender my shares?

If you are the record owner of your shares and you tender your shares directly to the Depositary, you will not have to pay brokerage fees or similar expenses. If you own your shares through a bank, broker, dealer, trust company or other nominee and that person tenders your shares on your behalf, other than the Dealer Manager, that person may charge you a fee for doing so. You should consult with your bank, broker, dealer, trust company or other nominee to determine whether any charges will apply. See Section 3.

Does the Company intend to repurchase any shares other than pursuant to the Offer during or after the Offer?

Rule 13e-4(f)(6) of the Exchange Act prohibits us and our affiliates from purchasing any shares, other than pursuant to the Offer, until at least ten business days after the expiration of the Offer, except pursuant to certain

v

limited exceptions provided in Rule 14e-5 of the Exchange Act. Beginning ten business days after the Expiration Time of the Offer, we may make stock repurchases from time to time on the open market and/or in private transactions. Whether we make additional repurchases will depend on many factors, including, without limitation, the number of shares, if any, that we purchase in the Offer, our business and financial performance and situation, the business and market conditions at the time, including the price of the shares, and such other factors as we may consider relevant. Any of these repurchases may be on the same terms or on terms that are more or less favorable to the selling stockholders in those transactions than the terms of the Offer.

What are the U.S. federal income tax consequences if I tender my shares?

Generally, a sale of shares pursuant to the Offer will be a taxable transaction for U.S. federal income tax purposes. The receipt of cash for your tendered shares will generally be treated for U.S. federal income tax purposes either as (1) a sale or exchange or (2) a distribution in respect of stock from the Company. See Section 14. We recommend that you consult with your tax advisor with respect to your particular situation.

Will I have to pay stock transfer tax if I tender my shares?

We will pay all stock transfer taxes unless payment is made to, or if shares not tendered or accepted for payment are to be registered in the name of, someone other than the registered holder, or tendered certificates are registered in the name of someone other than the person signing the Letter of Transmittal. See Section 5.

Who can I talk to if I have questions?

If you have any questions regarding the Offer, please contact D.F. King & Co., Inc., the Information Agent, or Citigroup Global Markets Inc., the Dealer Manager. Contact information for the Information Agent and the Dealer Manager is set forth on the back cover of this Offer to Purchase.

We invite our stockholders to tender shares of our common stock for purchase by us. Upon the terms and subject to the conditions of this Offer to Purchase and the related Letter of Transmittal, we are offering to purchase up to 2,666,666 shares of our common stock at a price of $15.00 per share, less any applicable withholding taxes and without interest.

The Offer will expire at 11:59 p.m., New York City time, on Tuesday, July 16, 2019, unless extended.

Only shares properly tendered and not properly withdrawn will be purchased. However, because of the proration and conditional tender offer provisions described in this Offer to Purchase, all of the shares tendered may not be purchased if more than the number of shares we seek are properly tendered and not properly withdrawn. We will return shares that we do not purchase because of proration or conditional tenders to the tendering stockholders at our expense promptly following the Expiration Time. See Section 1.

We expressly reserve the right to purchase more than 2,666,666 shares pursuant to the Offer, subject to certain limitations and legal requirements. See Sections 1 and 15.

Tendering stockholders whose shares are registered in their own names and who tender directly to American Stock Transfer & Trust Company, LLC, the Depositary, will not be obligated to pay brokerage fees or commissions or, except as set forth in Instruction 6 to the Letter of Transmittal, stock transfer taxes on the purchase of shares by us under the Offer. If you own your shares through a bank, broker, dealer, trust company or other nominee and that person tenders your shares on your behalf, other than the Dealer Manager, that person may charge you a fee for doing so. You should consult your bank, broker, dealer, trust company or other nominee to determine whether any charges will apply.

Holders of restricted stock unit awards may not tender such restricted stock units in the Offer unless and until the underlying shares have vested and the restrictions on such awards have lapsed.

This Offer is not conditioned upon any minimum number of shares being tendered. However, our obligation to accept, and pay for, shares validly tendered pursuant to the Offer is conditioned upon satisfaction or waiver of the conditions set forth in Section 7 of this Offer to Purchase.

Our Board of Directors has approved making the Offer. However, neither we nor our Board of Directors, the Dealer Manager, the Information Agent or the Depositary is making any recommendation whether you should tender or refrain from tendering your shares. We have not authorized any person to make any recommendation. You must decide whether to tender your shares and, if so, how many shares to tender. In so doing, you should read and evaluate carefully the information in, or incorporated by reference in, this Offer to Purchase and in the related Letter of Transmittal and should discuss whether to tender any of your shares with your broker or other financial or tax advisor. See Section 2.

The Company’s directors, executive officers and affiliates are entitled to participate in the Offer on the same basis as all other stockholders. We do not know whether or to what extent our directors or executive officers will participate in the Offer. In addition, the Affiliated Holders are also entitled to participate in the Offer on the same basis as all other stockholders. We do not know whether or to what extent the Affiliated Holders will participate in the Offer. The Affiliated Holders collectively held 40,518,819 shares, or approximately 63.7% of the issued and outstanding common stock as of June 14, 2019.

Section 14 of this Offer to Purchase describes certain U.S. federal income tax consequences of a sale of shares under the Offer.

We will pay the reasonable fees and expenses of Citigroup Global Markets Inc., the Dealer Manager, D.F. King & Co., Inc., the Information Agent, and American Stock Transfer & Trust Company, LLC, the Depositary, incurred in connection with this Offer. See Section 16.

As of June 14, 2019, there were 63,621,542 shares of our common stock issued and outstanding. The 2,666,666 shares that we are offering to purchase in the Offer represent approximately 4.2% of the total number of outstanding shares of our common stock as of June 14, 2019. The shares are listed and traded on OTCQX under the symbol “RVRA.” We announced our intention to make the Offer after the market closed on June 13, 2019. On June 13, 2019, the last trading day before that announcement, the OTCQX closing price per share of our common stock was $12.00. On June 17, 2019, the last full trading day before commencement of the Offer, the OTCQX closing price per share of our common stock was $12.48. The $15.00 purchase price per share in the Offer represents a premium of approximately 20.2% to the OTCQX closing price per share of our common stock on June 17, 2019. Stockholders are urged to obtain current market quotations for the shares. See Section 8.

THE TENDER OFFER

1. Number of Shares; Purchase Price; Proration

General. Upon the terms and subject to the conditions of the Offer, we will purchase 2,666,666 shares of our common stock, or if a lesser number of shares are properly tendered, all shares that are properly tendered and not properly withdrawn in accordance with Section 4, at a price of $15.00 per share, less any applicable withholding taxes and without interest.

The term “Expiration Time” means 11:59 p.m., New York City time, on Tuesday, July 16, 2019, unless we, in our sole discretion, shall have extended the period of time during which the Offer will remain open in which event the term “Expiration Time” shall refer to the latest time and date at which the Offer, as so extended by us, shall expire. See Section 15 for a description of our right to extend, delay, terminate or amend the Offer. In accordance with the rules of the Commission, we may, and we expressly reserve the right to, purchase under the Offer an additional amount of shares not to exceed 2% of our outstanding shares (approximately 1.3 million shares, based on 63,621,542 shares of our common stock issued and outstanding as of June 14, 2019) without amending or extending the Offer. See Section 15.

In the event of an over-subscription of the Offer as described below, shares tendered will be subject to proration, except for shares conditionally tendered for which the tender condition was not initially satisfied. The proration period and, except as described herein, withdrawal rights expire at the Expiration Time.

If we:

and the Offer is scheduled to expire at any time earlier than the expiration of a period ending at 12:00 midnight, New York City time, on the tenth business day (as defined below) from, and including, the date on which notice of any such increase or decrease is first published, sent or given in the manner specified in Section 15, then the Offer will be extended until the expiration of such period of ten business days. For the purposes of the Offer, a “business day” means any day other than a Saturday, Sunday or United States federal holiday and consists of the time period from 12:01 a.m. through 12:00 midnight, New York City time.

The Offer is not conditioned upon any minimum number of shares being tendered. However, the Offer is subject to certain other conditions. See Section 7.

Shares properly tendered under the Offer and not properly withdrawn will be purchased at the purchase price, upon the terms and subject to the conditions of the Offer, including the proration and conditional tender provisions. All shares tendered and not purchased under the Offer, including shares not purchased because of proration or conditional tender provisions, will be returned to the tendering stockholders or, in the case of shares delivered by book-entry transfer, credited to the account at the book-entry transfer facility from which the transfer had previously been made, at our expense promptly following the Expiration Time.

Priority of Purchases. Upon the terms and subject to the conditions of the Offer, if more than 2,666,666 shares, or such greater number of shares as we may elect to purchase, subject to applicable law, have been properly tendered and not properly withdrawn prior to the Expiration Time, we will purchase properly tendered shares on the basis set forth below:

3

As a result of the foregoing priorities applicable to the purchase of shares tendered, it is possible that all of the shares that a stockholder tenders in the Offer may not be purchased. In addition, if a tender is conditioned upon the purchase of a specified number of shares, it is possible that none of those shares will be purchased.

Proration. If proration of tendered shares is required, we will determine the proration factor promptly after the expiration of the Offer. Subject to adjustment to avoid the purchase of fractional shares and subject to the provisions governing conditional tenders described in Section 6, proration for each stockholder tendering shares, other than holders of shares conditionally tendered, will be based on the ratio of the number of shares properly tendered and not properly withdrawn by the stockholder to the total number of shares properly tendered and not properly withdrawn by all stockholders. We will announce the final proration factor and commence payment for any shares purchased pursuant to the tender offer promptly after the expiration of the Offer. The preliminary results of any proration will be announced by press release promptly after the expiration of the Offer. After the Expiration Time, stockholders may obtain preliminary proration information from the Information Agent and also may be able to obtain the information from their brokers.

As described in Section 14, the number of shares that we will purchase from a stockholder under the Offer may affect the U.S. federal income tax consequences to that stockholder and, therefore, may be relevant to a stockholder’s decision whether or not to tender shares.

This Offer to Purchase and the related Letter of Transmittal will be mailed to record holders of shares and will be furnished to brokers, dealers, commercial banks and trust companies whose names, or the names of whose nominees, appear on our stockholder list or, if applicable, who are listed as participants in a clearing agency’s security position listing for subsequent transmittal to beneficial owners of shares.

2. Purpose of the Tender Offer; Certain Effects of the Tender Offer; Other Plans

Purpose of the Tender Offer. On June 13, 2019, we announced our intention to commence a tender offer to purchase up to $40 million in shares of our common stock to be funded from cash on hand. On June 18, 2019, we commenced the tender offer to purchase up to 2,666,666 shares of our common stock at a price per share of $15.00 to be funded from cash on hand. Assuming that the maximum of 2,666,666 shares to be purchased are tendered in the Offer at a price of $15.00 per share, the aggregate purchase price will be approximately $40 million. As of June 15, 2019, we had approximately $74.6 million in cash and cash equivalents. We will use a portion of cash on hand to fund the Offer. Our Board of Directors, after evaluating expected capital requirements of our operations and other expected cash commitments, believes that purchasing shares of our common stock in the Offer represents a prudent use of the funds required for the Offer.

Our management and Board of Directors have evaluated our operations, strategy and expectations for the future and have carefully considered our business profile, assets and recent market prices for our common stock. In considering the Offer, our management and Board of Directors took into account the expected financial impact of the Offer, including the reduction in the amount of cash on hand as described in Section 9. Our Board of Directors believes that investing in our shares at this time is a prudent use of our financial resources. We believe that our current financial resources, including debt capacity, will allow us to fund capital requirements for improving our operations as well as providing appropriate financial flexibility for general corporate purposes. However, actual experience may differ significantly from our expectations. See “Forward-Looking Statements.”

4

The Offer represents an opportunity for us to return capital to our stockholders who elect to tender their shares, subject to the terms and conditions of the Offer. Additionally, stockholders who do not participate in the Offer will automatically increase their relative percentage interest in us and our future operations at no additional cost to them. The Offer also provides stockholders with an opportunity to obtain liquidity with respect to all or a portion of their shares, without potential disruption to the share price and the usual transaction costs associated with market sales. In addition, the Offer provides our stockholders with an efficient way to sell their shares without incurring brokers’ fees or commissions. Where shares are tendered by the registered owner of those shares directly to the Depositary, the sale of those shares in the Offer will permit the seller to avoid the usual transaction costs associated with open market sales.

Neither we nor any member of our Board of Directors, the Dealer Manager, the Information Agent or the Depositary makes any recommendation to any stockholder as to whether to tender or refrain from tendering any shares. We have not authorized any person to make any such recommendation. Stockholders should carefully evaluate all information in the Offer. Stockholders are also urged to consult with their tax advisors to determine the consequences to them of participating or not participating in the Offer, and should make their own decisions about whether to tender shares and, if so, how many shares to tender. In doing so, you should read carefully the information included in, and incorporated by reference in, this Offer to Purchase and in the related Letter of Transmittal.

Certain Effects of the Offer. Stockholders who do not tender their shares pursuant to the Offer and stockholders who otherwise retain an equity interest in the Company as a result of a partial tender of shares or proration will continue to be owners of the Company. As a result, those stockholders will realize a proportionate increase in their relative equity interest in the Company and will bear the attendant risks associated with owning our equity securities, including risks resulting from our purchase of shares. We can give no assurance, however, that we will not issue additional shares or equity interests in the future. Stockholders may be able to sell non-tendered shares in the future on the OTCQX or otherwise, at a net price significantly higher or lower than the purchase price in the Offer. We can give no assurance, however, as to the price at which a stockholder may be able to sell his or her shares in the future.

Shares we acquire pursuant to the Offer will be retired.

The completion of the Offer in accordance with its terms and conditions will not cause the Company to stop being subject to the periodic reporting requirements of the Exchange Act. We also do not expect the Offer to cause our common stock to cease to be traded on the OTCQX.

The Offer will reduce our “public float” (the number of shares owned by non-affiliate stockholders and available for trading in the securities markets), and is likely to reduce the number of our stockholders. These reductions may result in lower stock prices and/or reduced liquidity in the trading market for our common stock following completion of the Offer.

We may, in the future, decide to purchase shares. Any such purchases may be on the same terms as, or on terms that are more or less favorable to stockholders than, the terms of the Offer. Rule 13e-4(f)(6) under the Exchange Act, however, prohibits us and our affiliates from purchasing any shares, other than pursuant to the Offer, until at least ten business days after the Expiration Time, except pursuant to certain limited exceptions provided in Rule 14e-5 under the Exchange Act.

For information regarding the intentions of our directors and executive officers to tender in the Offer or sell shares in the open market during the pendency of the Offer, see Section 11.

5

Other Plans. Except as otherwise disclosed in this Offer to Purchase, including the documents incorporated by reference herein, we currently have no plans, proposals or negotiations underway that relate to or would result in:

Notwithstanding the foregoing, as part of our long-term corporate goal of increasing stockholder value, we regularly consider alternatives to enhance stockholder value, including repurchases of our shares in the open market, through block trades or in private transactions, strategic acquisitions, business combinations and divestitures, and we intend to continue to consider alternatives to enhance stockholder value. Except as otherwise disclosed in this Offer to Purchase, as of the date hereof, no agreements, understandings or decisions have been reached and there can be no assurance that we will decide to undertake any such alternatives.

3. Procedures for Tendering Shares

Valid Tender. For a stockholder to make a valid tender of shares under the Offer, (i) the Depositary must receive, at one of its addresses set forth on the back cover of this Offer to Purchase and prior to the Expiration Time:

(ii) the tendering stockholder must, before the Expiration Time, comply with the guaranteed delivery procedures we describe below.

If a broker, dealer, commercial bank, trust company or other nominee holds your shares, it is likely they have an earlier deadline for you to act to instruct them to accept the Offer on your behalf. We urge you to contact your broker, dealer, commercial bank, trust company or other nominee to find out their applicable deadline.

6

The valid tender of shares by you by one of the procedures described in this Section 3 will constitute a binding agreement between you and us on the terms of, and subject to the conditions to, the Offer.

We urge stockholders who hold shares through brokers or banks to consult the brokers or banks to determine whether transaction costs are applicable if they tender shares through the brokers or banks and not directly to the Depositary.

Book-Entry Transfer. For purposes of the Offer, the Depositary will establish an account for the shares at The Depository Trust Company (the “book-entry transfer facility”) within two business days after the date of this Offer to Purchase. Any financial institution that is a participant in the book-entry transfer facility’s system may make book-entry delivery of shares by causing the book-entry transfer facility to transfer those shares into the Depositary’s account in accordance with the book-entry transfer facility’s procedures for that transfer. Although delivery of shares may be effected through book-entry transfer into the Depositary’s account at the book-entry transfer facility, the Letter of Transmittal, properly completed and duly executed, with any required signature guarantees, or an agent’s message, and any other required documents must, in any case, be transmitted to, and received by, the Depositary at one of its addresses set forth on the back cover of this Offer to Purchase prior to the Expiration Time, or the tendering stockholder must comply with the guaranteed delivery procedures we describe below.

The confirmation of a book-entry transfer of shares into the Depositary’s account at the book-entry transfer facility as we describe above is referred to herein as a “book-entry confirmation.” Delivery of documents to the book-entry transfer facility in accordance with the book-entry transfer facility’s procedures will not constitute delivery to the Depositary.

The term “agent’s message” means a message transmitted by the book-entry transfer facility to, and received by, the Depositary and forming a part of a book-entry confirmation, stating that the book-entry transfer facility has received an express acknowledgment from the participant tendering shares through the book-entry transfer facility that the participant has received and agrees to be bound by the terms of the Letter of Transmittal and that we may enforce that agreement against that participant.

Method of Delivery. The method of delivery of shares, the Letter of Transmittal and all other required documents, including delivery through the book-entry transfer facility, is at the election and risk of the tendering stockholder. Shares will be deemed delivered only when actually received by the Depositary (including, in the case of a book-entry transfer, by book-entry confirmation). If you plan to make delivery by mail, we recommend that you deliver by registered mail with return receipt requested and obtain proper insurance. In all cases, sufficient time should be allowed to ensure timely delivery.

Signature Guarantees. No signature guarantee will be required on a Letter of Transmittal for shares tendered thereby if:

For purposes hereof, a “registered holder” of tendered shares will include any participant in the book-entry transfer facility’s system whose name appears on a security position listing as the owner of those shares, and an “eligible institution” is a “financial institution,” which term includes most commercial banks, savings and loan associations and brokerage houses, that are participants in any of the following: (i) the Securities Transfer Agents Medallion Program; (ii) the New York Stock Exchange, Inc. Medallion Signature Program; or (iii) the Stock Exchange Medallion Program.

7

Except as we describe above, all signatures on any Letter of Transmittal for shares tendered thereby must be guaranteed by an eligible institution. See Instructions 1, 5 and 7 to the Letter of Transmittal. If the certificates for shares are registered in the name of a person other than the signer of the Letter of Transmittal, or if payment is to be made or certificates for shares not tendered or not accepted for payment are to be returned to a person other than the registered holder of the certificates surrendered, then the tendered certificates must be endorsed or accompanied by appropriate stock powers, in either case signed exactly as the name or names of the registered holders or owners appear on the certificates, with the signatures on the certificates or stock powers guaranteed as aforesaid. See Instructions 1, 5 and 7 to the Letter of Transmittal.

Guaranteed Delivery. If you wish to tender shares under the Offer and your certificates for shares are not immediately available or the procedures for book-entry transfer cannot be completed on a timely basis or time will not permit all required documents to reach the Depositary prior to the Expiration Time, your tender may be effected if all the following conditions are met:

For these purposes, a “trading day” is any day on which The New York Stock Exchange is open for business.

A Notice of Guaranteed Delivery must be delivered to the Depositary by hand, overnight courier, facsimile transmission or mail before the Expiration Time and must include a guarantee by an eligible institution in the form set forth in the Notice of Guaranteed Delivery.

Restricted Stock Unit Awards. Holders of restricted stock unit awards may not tender the shares underlying such restricted stock unit awards in the Offer unless and until such shares have vested and the restrictions on such awards have lapsed. Once shares underlying the restricted stock unit awards have vested and the restrictions on such awards have lapsed, you may tender some or all of such shares in the Offer. See “—Valid Tender” above.

Return of Unpurchased Shares. The Depositary will return certificates for unpurchased shares promptly after the expiration or termination of the Offer or the proper withdrawal of the shares, as applicable, or, in the case of shares tendered by book-entry transfer at the book-entry transfer facility, the Depositary will credit the shares to the appropriate account maintained by the tendering stockholder at the book-entry transfer facility, in each case without expense to the stockholder.

Tendering Stockholder’s Representation and Warranty; Our Acceptance Constitutes an Agreement. It is a violation of Rule 14e-4 promulgated under the Exchange Act for a person acting alone or in concert with others, directly or indirectly, to tender shares for such person’s own account unless at the time of tender and at the Expiration Time such person has a “net long position” in (a) the shares that is equal to or greater than the amount tendered and will deliver or cause to be delivered such shares for the purpose of tendering to us within the period specified in the Offer or (b) other securities immediately convertible into, exercisable for or exchangeable into

8

shares (“Equivalent Securities”) that is equal to or greater than the amount tendered and, upon the acceptance of such tender, will acquire such shares by conversion, exchange or exercise of such Equivalent Securities to the extent required by the terms of the Offer and will deliver or cause to be delivered such shares so acquired for the purpose of tender to us within the period specified in the Offer. Rule 14e-4 also provides a similar restriction applicable to the tender or guarantee of a tender on behalf of another person. A tender of shares made pursuant to any method of delivery set forth herein will constitute the tendering stockholder’s acceptance of the terms and conditions of the Offer, as well as the tendering stockholder’s representation and warranty to us that (a) such stockholder has a “net long position” in shares or Equivalent Securities at least equal to the shares being tendered within the meaning of Rule 14e-4, and (b) such tender of shares complies with Rule 14e-4. Our acceptance for payment of shares tendered pursuant to the Offer will constitute a binding agreement between the tendering stockholder and us upon the terms and subject to the conditions of the Offer, which agreement will be governed by, and construed in accordance with, the laws of the State of New York.

Determination of Validity; Rejection of Shares; Waiver of Defects; No Obligation to Give Notice of Defects. All questions as to the number of shares to be accepted, the price to be paid for shares to be accepted and the validity, form, eligibility (including time of receipt) and acceptance for payment of any tender of shares will be determined by us, in our sole discretion, and our determination will be final and binding on all parties, subject to a stockholder’s right to challenge our determination in a court of competent jurisdiction. We reserve the absolute right prior to the Expiration Time to reject any or all tenders we determine not to be in proper form or the acceptance for payment of or payment for which may, in the opinion of our counsel, be unlawful. We also reserve the absolute right, subject to applicable law, to waive any conditions of the Offer with respect to all stockholders or any defect or irregularity in any tender with respect to any particular shares or any particular stockholder whether or not we waive similar defects or irregularities in the case of other stockholders. No tender of shares will be deemed to have been validly made until all defects or irregularities relating thereto have been cured or waived. None of us, the Dealer Manager, the Information Agent, the Depositary or any other person will be under any duty to give notification of any defects or irregularities in tenders or incur any liability for failure to give any such notification. Our interpretation of the terms of and conditions to the Offer, including the Letter of Transmittal and the instructions thereto, will be final and binding on all parties, subject to a stockholder’s right to challenge our determination in a court of competent jurisdiction. By tendering shares to us, you agree to accept all decisions we make concerning these matters and waive any right you might otherwise have to challenge those decisions.

U.S. Federal Backup Withholding Tax. Under the U.S. federal backup withholding tax rules, 24% of the gross proceeds payable to a stockholder or other payee in the Offer must be withheld and remitted to the Internal Revenue Service (the “IRS”) unless the stockholder or other payee provides such person’s taxpayer identification number (generally an employer identification number or social security number) to the Depositary or other applicable tax withholding agent or other payor and certifies under penalties of perjury that this number is correct or otherwise establishes an exemption. If the Depositary or other applicable tax withholding agent or other payor is not provided with the correct taxpayer identification number or another adequate basis for exemption, the stockholder may be subject to backup withholding tax and may be subject to certain penalties imposed by the IRS. Therefore, each tendering stockholder that is a U.S. Holder (as defined in Section 14) should complete and sign the IRS Form W-9 included as part of the Letter of Transmittal in order to provide the information and certification necessary to avoid the backup withholding tax, unless the stockholder otherwise establishes an exemption from the backup withholding tax to the satisfaction of the Depositary or other applicable tax withholding agent. The backup withholding tax is not an additional tax, and any amounts withheld under the backup withholding tax rules will be allowed as a refund or credit against a stockholder’s U.S. federal income tax liability provided the required information is timely furnished to the IRS.

Certain stockholders (including, among others, all corporations and certain Non-U.S. Holders (as defined in Section 14)) are not subject to these backup withholding tax rules. In order for a Non-U.S. Holder to qualify as an exempt recipient, that stockholder must submit an IRS Form W-8BEN or W-8BEN-E (or other applicable form), signed under penalties of perjury, attesting to that stockholder’s non-U.S. status. The applicable form can be

9

obtained from the IRS website, https://www.irs.gov, or from the Depositary at the address and telephone number set forth in the back cover page of this Offer to Purchase. See Instruction 9 of the Letter of Transmittal. A Non-U.S. Holder that submits a properly completed IRS Form W-8BEN or W-8BEN-E may still be subject to the regular U.S. federal withholding tax on gross proceeds payable to such holder. See Withholding for Non-U.S. Holders below and Section 14.

Stockholders are urged to consult their own tax advisors regarding possible qualifications for exemption from backup withholding tax and the procedure for obtaining any applicable exemption.

For a discussion of certain U.S. federal income tax consequences to tendering stockholders, see Section 14.

Withholding For Non-U.S. Holders. A payment made to a Non-U.S. Holder pursuant to the Offer will be subject to U.S. federal income and withholding tax unless the Non-U.S. Holder meets the complete termination, “substantially disproportionate,” or “not essentially equivalent to a dividend” test described in Section 14. If a Non-U.S. Holder tenders shares held in a U.S. brokerage account or otherwise through a U.S. broker, dealer, commercial bank, trust company, or other nominee, such U.S. broker or other nominee will generally be the withholding agent for the payment made to the Non-U.S. Holder pursuant to the Offer. Such U.S. brokers or other nominees may withhold or require certifications in this regard. Non-U.S. Holders tendering shares held through a U.S. broker or other nominee should consult such U.S. broker or other nominee and their own tax advisors to determine the particular withholding procedures that will be applicable to them. Notwithstanding the foregoing, even if a Non-U.S. Holder tenders shares held in its own name as a holder of record and delivers to the Depositary or other applicable tax withholding agent a properly completed IRS Form W-8BEN or W-8BEN-E (or other applicable form) before any payment is made, it is possible that one or more of the Depositary or other applicable tax withholding agents may withhold 30% of the gross proceeds unless the Depositary or the other applicable tax withholding agent determines that a reduced rate under an applicable income tax treaty or exemption from withholding is applicable, regardless of whether the payment is properly exempt from U.S. federal gross income tax under the complete termination, “substantially disproportionate,” or “not essentially equivalent to a dividend” test.

To obtain a reduced rate of withholding under an applicable tax treaty, a Non-U.S. Holder must deliver to the Depositary or other applicable tax withholding agent a properly completed IRS Form W-8BEN or W-8BEN-E (or other applicable form) before the payment is made. To obtain an exemption from withholding on the grounds that the gross proceeds paid pursuant to the Offer are effectively connected with the conduct of a trade or business within the United States, a Non-U.S. Holder must deliver to the Depositary or other applicable tax withholding agent a properly completed IRS Form W-8ECI (or successor form). The applicable form can be obtained from the Depositary at the address and telephone number set forth in the back cover page of this Offer to Purchase. A Non-U.S. Holder that qualifies for an exemption from withholding on these grounds generally will be required to file a U.S. federal income tax return and generally will be subject to U.S. federal income tax on income derived from the sale of shares pursuant to the Offer in the manner and to the extent described in Section 14 as if it were a U.S. Holder, and in the case of a foreign corporation, an additional branch profits tax may be imposed at a rate of 30% (or a lower rate specified in an applicable income tax treaty), with respect to such income.

A Non-U.S. Holder may be eligible to obtain a refund of all or a portion of any tax withheld if the Non-U.S. Holder (i) meets the complete termination, “substantially disproportionate” or “not essentially equivalent to a dividend” tests described in Section 14 that would characterize the exchange as a sale (as opposed to a dividend) with respect to which the Non-U.S. Holder is not subject to U.S. federal income tax or (ii) is otherwise able to establish that no tax or a reduced amount of tax is due.

Non-U.S. Holders are urged to consult their own tax advisors regarding the application of U.S. federal income tax withholding, including eligibility for a withholding tax reduction or exemption, and the refund procedure.

10

FIRPTA Withholding. In order to ensure compliance with withholding requirements under FIRPTA (as defined in Section 14), all participating Holders must submit a certification that demonstrates such Holder is not subject to FIRPTA withholding. U.S. Holders may meet this requirement by submitting a properly completed an IRS Form W-9. Non-U.S. Holders must submit a FIRPTA Certificate (which shall be attached to the Letter of Transmittal and Letter to Clients) and CHECK BOX 1 certifying that such Non-U.S. Holder’s ownership of the shares has not exceeded the requisite threshold. If a Non-U.S. Holder is unable to make the certification in BOX 1 on the FIRPTA Certificate, such Non-U.S. Holder must submit the enclosed FIRPTA Certificate and CHECK BOX 2 certifying that such Non-U.S. Holder shall take necessary steps to ensure that his, her or its broker or other financial or tax advisor withholds, and promptly pays over, an amount necessary to satisfy any applicable FIRPTA Withholding obligations. By participating in the Offer and CHECKING BOX 2 on the FIRPTA Certificate, you expressly agree to indemnify and hold the Company harmless for any liability related to any FIRPTA withholding obligations.

Lost Certificates. If the share certificates which a registered holder wants to surrender have been lost, destroyed or stolen, the stockholder should promptly notify the Depositary’s Shareholder Services Department at 1-800-937-5449. The Depositary will instruct the stockholder as to the steps that must be taken in order to replace the certificates.

Certificates for shares, together with a properly completed and duly executed letter of transmittal or facsimile thereof, or an agent’s message, and any other documents required by the letter of transmittal, must be delivered to the Depositary and not to us or the Dealer Manager or Information Agent. Any such documents delivered to us or the Dealer Manager or Information Agent will not be deemed to be properly tendered.

4. Withdrawal Rights

Except as this Section 4 otherwise provides, tenders of shares are irrevocable. You may withdraw shares that you have previously tendered under the Offer according to the procedures we describe below at any time prior to the Expiration Time for all shares. You may also withdraw your previously tendered shares at any time after 11:59 p.m., New York City time, on Tuesday, August 13, 2019, the 40^th business day after the commencement of the Offer, unless such shares have been accepted for payment as provided in the Offer.

For a withdrawal to be effective, a written, telegraphic or facsimile transmission notice of withdrawal must:

If certificates for shares have been delivered or otherwise identified to the Depositary, then, prior to the physical release of those certificates, the serial numbers shown on those certificates must be submitted to the Depositary and, unless an eligible institution has tendered those shares, an eligible institution must guarantee the signatures on the notice of withdrawal.

If a stockholder has used more than one Letter of Transmittal or has otherwise tendered shares in more than one group of shares, the stockholder may withdraw shares using either separate notices of withdrawal or a combined notice of withdrawal, so long as the information specified above is included. If shares have been delivered in accordance with the procedures for book-entry transfer described in Section 3, any notice of withdrawal must also specify the name and number of the account at the book-entry transfer facility to be credited with the withdrawn shares and otherwise comply with the book-entry transfer facility’s procedures.

11

Withdrawals of tendered shares may not be rescinded, and any shares properly withdrawn will thereafter be deemed not validly tendered for purposes of the Offer. Withdrawn shares may be retendered at any time prior to the Expiration Time by again following one of the procedures described in Section 3.

We will decide, in our sole discretion, all questions as to the form and validity, including time of receipt, of notices of withdrawal, and each such decision will be final and binding on all parties, subject to a stockholder’s right to challenge our determination in a court of competent jurisdiction. We also reserve the absolute right to waive any defect or irregularity in the withdrawal of shares by any stockholder, whether or not we waive similar defects or irregularities in the case of any other stockholder. None of us, the Dealer Manager, the Information Agent, the Depositary or any other person will be under any duty to give notification of any defects or irregularities in any notice of withdrawal or incur any liability for failure to give any such notification.

If we extend the Offer, are delayed in our purchase of shares, or are unable to purchase shares under the Offer as a result of the occurrence of a condition disclosed in Section 7, then, without prejudice to our rights under the Offer, the Depositary may, subject to applicable law, retain tendered shares on our behalf, and such shares may not be withdrawn except to the extent tendering stockholders are entitled to withdrawal rights as described in this Section 4. Our reservation of the right to delay payment for shares which we have accepted for payment is limited by Rule 13e-4(f)(5) promulgated under the Exchange Act, which requires that we must pay the consideration offered or return the shares tendered promptly after termination or withdrawal of a tender offer.

5. Purchase of Shares and Payment of Purchase Price

Upon the terms and subject to the conditions of the Offer, promptly following the Expiration Time, we will accept for payment and pay the purchase price for (and thereby purchase) up to 2,666,666 shares (or such greater number of shares as we may elect to purchase, subject to applicable law) properly tendered and not properly withdrawn before the Expiration Time.

For purposes of the Offer, we will be deemed to have accepted for payment (and therefore purchased), subject to the proration and conditional tender provisions of this Offer, shares that are properly tendered and not properly withdrawn only when, as and if we give oral or written notice to the Depositary of our acceptance of the shares for payment pursuant to the Offer.

In all cases, payment for shares tendered and accepted for payment pursuant to the Offer will be made promptly, subject to possible delay in the event of proration, but only after timely receipt by the Depositary of:

We will pay for shares purchased pursuant to the Offer by depositing the aggregate purchase price for the shares with the Depositary, which will act as agent for tendering stockholders for the purpose of receiving payment from us and transmitting payment to the tendering stockholders.

In the event of proration, we will determine the proration factor and pay for those tendered shares accepted for payment promptly after the expiration of the Offer. Certificates for all shares tendered and not purchased, including shares not purchased due to proration or conditional tender, will be returned or, in the case of shares tendered by book-entry transfer, will be credited to the account maintained with the book-entry transfer facility by the participant who delivered the shares, to the tendering stockholder at our expense promptly after the Expiration Time.

12

Under no circumstances will we pay interest on the purchase price, including but not limited to, by reason of any delay in making payment. In addition, if certain events occur, we may not be obligated to purchase shares pursuant to the Offer. See Section 7.

We will pay all stock transfer taxes, if any, payable on the transfer to us of shares purchased pursuant to the Offer. If, however, payment of the purchase price is to be made to, or (in the circumstances permitted by the Offer) if unpurchased shares are to be registered in the name of, any person other than the registered holder, or if tendered certificates are registered in the name of any person other than the person signing the Letter of Transmittal, the amount of all stock transfer taxes, if any (whether imposed on the registered holder or the other person), payable on account of the transfer to the person will be deducted from the purchase price unless satisfactory evidence of the payment of the stock transfer taxes, or exemption from payment of the stock transfer taxes, is submitted. See Instruction 7 of the Letter of Transmittal.

Any tendering stockholder or other payee who fails to properly complete, sign and return to the Depositary (or other payor) the IRS Form W-9 included with the Letter of Transmittal or, in the case of a Non-U.S. Holder (as defined in Section 14), an IRS Form W-8BEN or W-8BEN-E (or other applicable or suitable substitute forms), may be subject to required U.S. federal backup withholding tax of 24% of the gross proceeds paid to the stockholder or other payee pursuant to the Offer. See Section 3. A Non-U.S. Holder that submits a properly completed IRS Form W-8BEN or W-8BEN-E may still be subject to the regular U.S. federal withholding tax on the gross proceeds payable to such holder. And any Holder may be subject to withholding under FIRPTA unless an IRS Form W-9 or a FIRPTA Certificate is submitted.

6. Conditional Tender of Shares

In the event of an over-subscription of the Offer, shares tendered prior to the Expiration Time will be subject to proration. See Section 1. As discussed in Section 14, the number of shares to be purchased from a particular stockholder may affect the U.S. federal income tax treatment of the purchase to the stockholder and the stockholder’s decision whether to tender. The conditional tender alternative is made available for stockholders seeking to take steps to have shares sold pursuant to the offer treated as a sale or exchange of such shares by the stockholder, rather than a distribution to the stockholder, for U.S. federal income tax purposes. Accordingly, a stockholder may tender shares subject to the condition that a specified minimum number of the stockholder’s shares tendered pursuant to a Letter of Transmittal must be purchased if any shares tendered are purchased. Any stockholder desiring to make a conditional tender must so indicate in the box entitled “Conditional Tender” in the Letter of Transmittal, and, if applicable, in the Notice of Guaranteed Delivery. It is the tendering stockholder’s responsibility to calculate the minimum number of shares that must be purchased from the stockholder in order for the stockholder to qualify for sale or exchange (rather than distribution) treatment for U.S. federal income tax purposes. Stockholders are urged to consult with their tax advisors. No assurances can be provided that a conditional tender will achieve the intended U.S. federal income tax result in all cases.

Any tendering stockholder wishing to make a conditional tender must calculate and appropriately indicate the minimum number of shares that must be purchased if any are to be purchased. After the Offer expires, if more than 2,666,666 shares (or such greater number of shares as we may elect to purchase, subject to applicable law) are properly tendered and not properly withdrawn, so that we must prorate our acceptance of and payment for tendered shares, we will calculate a preliminary proration percentage based upon all shares properly tendered, conditionally or unconditionally. If the effect of this preliminary proration would be to reduce the number of shares to be purchased from any stockholder below the minimum number specified, the tender will automatically be regarded as withdrawn (except as provided in the next paragraph). All shares tendered by a stockholder subject to a conditional tender and regarded as withdrawn as a result of proration will be returned at our expense, promptly after the Expiration Time.

After giving effect to these withdrawals, we will accept the remaining shares properly tendered, conditionally or unconditionally, on a pro rata basis, if necessary. If conditional tenders would otherwise be

13

regarded as withdrawn and would cause the total number of shares to be purchased to fall below 2,666,666 (or such greater number of shares as we may elect to purchase, subject to applicable law), then, to the extent feasible, we will select enough of the conditional tenders that would otherwise have been withdrawn to permit us to purchase 2,666,666 shares (or such greater number of shares as we may elect to purchase, subject to applicable law). In selecting among the conditional tenders, we will select by random lot, treating all tenders by a particular stockholder as a single lot, and will limit our purchase in each case to the designated minimum number of shares to be purchased. To be eligible for purchase by random lot, stockholders whose shares are conditionally tendered must have tendered all of their shares.

We expressly reserve the right to purchase additional shares, up to 2% of our outstanding shares (approximately 1.3 million shares, based on 63,621,542 shares of our common stock issued and outstanding as of June 14, 2019), without extending the Offer, and could decide to purchase more shares, subject to applicable legal requirements.

7. Conditions of the Tender Offer

Notwithstanding any other provision of the Offer (but subject to the provisions of Section 15), we will not be required to accept for payment, purchase or pay for any shares tendered, and may terminate or amend the Offer or may postpone the acceptance for payment of, or the purchase of and the payment for shares tendered, subject to Rule 13e-4(f) under the Exchange Act (which requires that the issuer making the tender offer either pay the consideration offered or return tendered securities promptly after the termination or withdrawal of the tender offer), if at any time on or after June 18, 2019 and prior to the Expiration Time (whether any shares have theretofore been accepted for payment) any of the following events has occurred (or shall have been reasonably determined by us to have occurred) that, in our reasonable judgment and regardless of the circumstances giving rise to the event or events, make it inadvisable to proceed with the Offer or with acceptance for payment:

14

The conditions referred to above are for our sole benefit and may be asserted by us regardless of the circumstances giving rise to any of these conditions, and may be waived by us, in whole or in part, at any time and from time to time in our reasonable discretion before the Expiration Time.

Our failure at any time to exercise any of the foregoing rights will not be deemed a waiver of any such right. Each such right is an ongoing right and may be asserted at any time and from time to time. In certain

15

circumstances, if we waive any of the conditions described above, we may be required to extend the Offer. See Section 15. Any determination by us concerning the events described in this section will be final and binding upon all persons.

8. Price Range of Shares; Dividends

Price Range of Shares. The common stock is quoted on the OTCQX under the symbol “RVRA” and has been trading since August 8, 2018.

As of June 14, 2019 we had 63,621,542 shares of common stock outstanding. As of June 14, 2019, we had fewer than 300 holders of record of common stock based on information provided by our transfer agent.

We announced our intention to make the Offer after the market closed on June 13, 2019. On June 13, 2019, the last trading day before that announcement, the OTCQX closing price per share of our common stock was $12.00. On June 17, 2019, the last full trading day before commencement of the Offer, the OTCQX closing price per share of our common stock was $12.48. The $15.00 purchase price per share in the Offer represents a premium of approximately 20.2% to the OTCQX closing price per share of our common stock on June 17, 2019. Stockholders are urged to obtain current market quotations for the shares. See Section 8.

Dividends. We do not intend to pay cash dividends on our common stock in the foreseeable future. We currently intend to retain any earnings for the future operation and development of our business, including exploration, development and acquisition activities. Any decision to declare and pay dividends will be made at the sole discretion of our Board of Directors and will depend on, among other things, our results of operations, cash requirements, financial condition, contractual restrictions and other factors that our Board of Directors may deem relevant. There can be no assurance that a payment of a dividend will occur in the future. Any future payment of cash dividends would be subject to the restrictions of our credit facilities.

9. Source and Amount of Funds

Assuming that 2,666,666 shares are purchased in the Offer at a price of $15.00 per share, the aggregate purchase price will be approximately $40 million.

We anticipate that we will pay for the shares tendered in the Offer and all fees and expenses applicable to the Offer from cash on hand. As of June 15, 2019, we had approximately $74.6 million in cash and cash equivalents. The Offer is not conditioned upon the receipt of financing. See Section 7 and Section 10.

10. Certain Information Concerning the Company

Overview. We are an independent oil and natural gas company with a strategic focus on efficiently operating our mature low-decline assets, developing our growth-oriented assets, and returning capital to shareholders. Our properties are currently located in six operating regions in the United States: the Hugoton Basin, East Texas, Michigan/Illinois, the Mid-Continent, North Louisiana and the Uinta Basin. We also own Blue Mountain Midstream LLC (“Blue Mountain”), which owns a state of the art cryogenic natural gas processing facility and a network of gathering pipelines and compressors located in the Merge/SCOOP/STACK play.

The Spin-Off. In the second quarter of 2018, Linn Energy, Inc. (“Linn”) and certain of its subsidiaries undertook an internal reorganization (including the conversion of Riviera Resources, LLC from a limited liability company to a corporation named Riviera Resources, Inc.), following which Riviera holds, directly or through its subsidiaries, substantially all of the assets of Linn and its consolidated subsidiaries, other than Linn’s 50% equity interest in Roan Resources LLC (“Roan”). A subsidiary of the Company held the equity interest in Roan until Linn’s internal reorganization on July 25, 2018. Following the internal reorganization, Linn distributed all of the outstanding shares of Riviera common stock to Linn’s shareholders on a pro rata basis (the “Spin-off”). The Spin-off was completed on August 7, 2018.

As of June 14, 2019, there were 63,621,542 shares of our common stock issued and outstanding. The 2,666,666 shares we are offering to purchase under the Offer represent approximately 4.2% of the total number of outstanding shares as of June 14, 2019.

The Company’s directors, executive officers and affiliates are entitled to participate in the Offer on the same basis as all other stockholders. We do not know whether or to what extent our directors or executive officers will participate in the Offer. As of June 14, 2019, our directors and executive officers as a group (10 persons) beneficially owned an aggregate of 319,466 shares, representing less than 1% of the total number of outstanding shares.

19

Omnibus Incentive Plan

In August 2018, in connection with the Spin-off, the Company implemented the Riviera Resources, Inc. 2018 Omnibus Incentive Plan (the “Omnibus Incentive Plan”) pursuant to which employees, consultants and non-employee directors of the Company and its affiliates are eligible to receive stock options, restricted stock, dividend equivalents, performance awards, other stock-based awards and other cash-based awards.

The Committee (as defined in the Omnibus Incentive Plan) has broad authority under the Omnibus Incentive Plan to, among other things: (i) select participants; (ii) determine the types of awards that participants receive and the number of shares that are subject to such awards; and (iii) establish the terms and conditions of awards, including the price (if any) to be paid for the shares or the award. As of June 14, 2019, up to 1,296,385 shares of common stock were available for issuance under the Omnibus Incentive Plan, and 2,557,520 shares of common stock had been awarded and remained unvested under the Omnibus Incentive Plan. If any stock option or other stock-based award granted under the Omnibus Incentive Plan expires, terminates or is canceled for any reason without having been exercised in full, the number of shares of common stock underlying any unexercised award shall again be available for the purpose of awards under the Omnibus Incentive Plan. If any shares of restricted stock, performance awards or other stock-based awards denominated in shares of common stock awarded under the Omnibus Incentive Plan are forfeited for any reason, the number of forfeited shares shall again be available for purposes of awards under the Omnibus Incentive Plan. Any award under the Omnibus Incentive Plan settled in cash shall not be counted against the maximum share limitation.

As is customary in incentive plans of this nature, each share limit and the number and kind of shares available under the Omnibus Incentive Plan and any outstanding awards, as well as the exercise or purchase prices of awards, and performance targets under certain types of performance-based awards, are subject to adjustment in the event of certain reorganizations, mergers, combinations, recapitalizations, stock splits, stock dividends or other similar events that change the number or kind of shares outstanding, and extraordinary dividends or distributions of property to the Company’s shareholders.

Pursuant to the Spin-off, on August 7, 2018, certain employees of the Company, including all of the executive officers, received 520,837 restricted stock units.

Agreements with Executive Officers and Directors

Employment Agreement with Our Chief Executive Officer

On and effective as of February 28, 2017, Linn entered into a third amended and restated employment agreement with David B. Rottino (the “Rottino Agreement”), our President and Chief Executive Officer. The Rottino Agreement reflects Mr. Rottino’s current base salary of $500,000 and eligibility for an annual bonus.

The Rottino Agreement provides Mr. Rottino with cash severance benefits payable upon a termination of employment without “cause” or by Mr. Rottino for “good reason” equal to: (i) two times the sum of (x) his base

20

salary at the highest rate in effect at any time during the 36-month period immediately preceding the employment termination date (the “Rottino Highest Base Salary”), plus (y) his target bonus for the year in which his termination occurs, if the termination does not occur within the six months preceding or the two years following a “change of control” (as defined in the Rottino Agreement), and (ii) the sum of (x) the Rottino Highest Base Salary, plus (y) his highest annual bonus paid in the 36-month period immediately preceding the “change of control,” if the termination does occur within the six months preceding or the two years following a “change of control.”

The Rottino Agreement also provides that, upon a termination of employment due to his death or “disability,” without “cause” or by Mr. Rottino for “good reason” (as each term is defined in the Rottino Agreement), all of Mr. Rottino’s outstanding and unvested long-term incentive awards will immediately vest, provided that any unvested appreciation profits interests, issued under the Linn Energy Holdco LLC Incentive Interest Plan, will only vest to the extent the applicable performance condition is satisfied (i) on the employment termination date, or (ii) within 120 days following the employment termination date. As of the date hereof, all such performance conditions have been satisfied.

The Rottino Agreement provides for a Code Section 280G “best-net” cutback, which would cause an automatic reduction in Mr. Rottino’s “change of control” severance payments and benefits in the event such reduction would result in Mr. Rottino receiving greater payments and benefits on an after-tax basis.

Offer Letter with our Executive Vice President and Chief Operating Officer

On March 19, 2018, Linn entered into an offer letter with Mr. Furbee (the “Furbee Agreement”). Pursuant to the terms of the Furbee Agreement, Mr. Furbee serves as our Executive Vice President and Chief Operating Officer. The Furbee Agreement provides for a base salary of $325,000 and current target bonus of 60% of base salary. Pursuant to the Furbee Agreement, Mr. Furbee is an employee “at will.”

Employment Agreement with Blue Mountain Chief Executive Officer

On March 29, 2018, Blue Mountain entered into an employment agreement with Mr. Harper (the “Harper Agreement”), effective as of April 2, 2018. Pursuant to the Harper Agreement, Mr. Harper will serve as Blue Mountain’s Chief Executive Officer for an initial three-year term, with automatic 12-month renewals thereafter, unless either party provides 60 days’ advance notice of non-renewal. The Harper Agreement reflects Mr. Harper’s current base salary of $480,000 per year and eligibility for an annual bonus with a target of 100% of Mr. Harper’s base salary (and a maximum bonus of 200%). In addition, pursuant to the Harper Agreement, Blue Mountain has created a management equity plan pursuant to which Blue Mountain has granted Mr. Harper restricted security units subject to time-vesting and restricted security units subject to performance-vesting.

The Harper Agreement provides Mr. Harper with the following cash severance benefits upon a termination of his employment prior to the expiration of his initial or renewed term (i) by Blue Mountain without “cause” or (ii) by Mr. Harper for “good reason” (as such terms are defined in the Harper Agreement), subject to his execution and non-revocation of a release of claims and continued compliance with restrictive covenants: (x) 12 months’ worth of his base salary for the year in which the termination date occurs, plus (y) his target bonus for the year in which the termination date occurs. In addition, he will receive any earned but unpaid annual bonus for the year prior to the year in which the termination date occurs (“earned bonus”), and be eligible to receive a pro rata annual bonus for the year in which the termination date occurs (“pro rata bonus”). If Mr. Harper’s employment terminates upon the expiration of his initial or renewed term as a result of Blue Mountain’s non-renewal of his employment term, he will receive the earned bonus and be eligible to receive a pro rata bonus, subject to his execution and non-revocation of a release of claims and continued compliance with restrictive covenants.

The Harper Agreement provides for a Code Section 280G “best-net” cutback, which would cause an automatic reduction in Mr. Harper’s “change of control” payments and benefits (whether provided under the

21

Harper Agreement or otherwise) in the event such reduction would result in Mr. Harper receiving greater payments and benefits on an after-tax basis.

Indemnity Agreements

On August 7, 2018, the Company entered into individual indemnity agreements with each of the executive officers and directors of the Company. The indemnity agreements require the Company to indemnify these individuals to the fullest extent permitted under Delaware law against liability that may arise by reason of their service to the Company, and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified. The Company may enter into indemnity agreements with any future directors or executive officers.

Registration Rights Agreement

In connection with the Spin-off, we entered into a registration rights agreement (the “Registration Rights Agreement”) with certain of our stockholders that owned at least 10% of our common stock or that were otherwise reasonably determined to be an affiliate of us, including certain funds affiliated with Fir Tree Capital Management LP, Elliott Associates, L.P. and York Capital Management, L.P. (collectively, the “Registration Rights Holders”).

The Registration Rights Agreement requires us, within 60 calendar days following the effective date of the Spin-off, subject to certain exceptions, to file a shelf registration statement that includes the Registrable Securities (as defined in the Registration Rights Agreement) whose inclusion has been timely requested. The Registration Rights Agreement also provides the Registration Rights Holders the ability to demand registrations or underwritten shelf takedowns subject to certain requirements and exceptions. In addition, if we propose to register shares of our common stock in certain circumstances, the Registration Rights Holders will have certain “piggyback” registration rights, subject to restrictions set forth in the Registration Rights Agreement, to include their shares of our common stock in the registration statement.

The Registration Rights Agreement also provides that (a) for so long as we are subject to the requirements to publicly file information or reports with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, we will use best efforts to timely file all information and reports with the Commission and comply with all such requirements, and (b) if we are not subject to the requirements of Section 13 or 15(d) of the Exchange Act, make available information necessary to comply with Section 4(a)(7) of the Securities Act and Rule 144 and Rule 144A, if available with respect to resales of the Registrable Securities under the Securities Act, at all times, all to the extent required from time to time to enable such Registration Rights Holder to sell Registrable Securities without registration under the Securities Act.

22

Recent Securities Transactions

Based on our records and to the best of our knowledge, except as set forth below, no transactions in our common stock have been effected in the past 60 days by us or our executive officers, directors, affiliates or subsidiaries or by the executive officers or directors of our subsidiaries:

23

24

All transactions above were completed under our previously announced share repurchase program.

In addition, as described in Section 10, on August 7, 2018, Linn completed the Spin-off by distributing to its stockholders all of the issued and outstanding common stock of the Company on a pro rata basis.

12. Effects of the Tender Offer on the Market for Shares; Registration under the Exchange Act

The purchase by us of shares under the Offer will reduce the number of shares that might otherwise be traded publicly and is likely to reduce the number of stockholders. As a result, trading of equivalent volumes of

25

the shares after consummation of the Offer may have a greater impact on trading prices than would be the case prior to consummation of the Offer.

We believe that there will be a sufficient number of shares outstanding and publicly traded following completion of the Offer to ensure a continued trading market for the shares. We do not expect the Offer to cause our common stock to cease to be traded on the OTCQX. The completion of the Offer in accordance with its terms and conditions will not cause the Company to stop being subject to the periodic reporting requirements of the Exchange Act.

Shares are currently “margin securities” under the rules of the Federal Reserve Board. This has the effect, among other things, of allowing brokers to extend credit to their customers using such shares as collateral. We believe that, following the purchase of shares under the Offer, the shares will continue to be “margin securities” for purposes of the Federal Reserve Board’s margin rules and regulations.

13. Legal Matters; Regulatory Approvals

We are not aware of any license or regulatory permit that is material to our business that might be adversely affected by our acquisition of shares as contemplated by the Offer or of any approval or other action by any government or governmental, administrative or regulatory authority or agency, domestic, foreign or supranational, that would be required for the acquisition or ownership of shares by us as contemplated by the Offer. Should any such approval or other action be required, we presently contemplate that we will seek that approval or other action. We are unable to predict whether we will be required to delay the acceptance for payment of or payment for shares tendered under the Offer pending the outcome of any such matter. There can be no assurance that any such approval or other action, if needed, would be obtained or would be obtained without substantial cost or conditions or that the failure to obtain the approval or other action might not result in adverse consequences to its business and financial condition. Our obligations under the Offer to accept for payment and pay for shares is subject to conditions. See Section 7.

14. Certain U.S. Federal Income Tax Consequences

General. The following discussion is a summary of certain U.S. federal income tax consequences to stockholders with respect to a sale of shares for cash pursuant to the Offer. The discussion is based upon the provisions of the Code, Treasury regulations, administrative pronouncements of the IRS and judicial decisions, all in effect as of the date hereof and all of which are subject to change, possibly with retroactive effect, or differing interpretations. The discussion does not address all aspects of U.S. federal income taxation that may be relevant to a particular stockholder in light of the stockholder’s particular circumstances or to certain types of stockholders subject to special treatment under the U.S. federal income tax laws, such as financial institutions, tax-exempt organizations, life insurance companies, dealers in securities or currencies, employee benefit plans, U.S. Holders (as defined below) whose “functional currency” is not the U.S. dollar, partnerships or other entities treated as partnerships for U.S. federal income tax purposes, stockholders holding the shares as part of a conversion transaction, as part of a hedge or hedging transaction, or as a position in a straddle for U.S. federal income tax purposes or persons who received their shares through exercise of employee stock options or otherwise as compensation. In addition, the discussion below does not consider the effect of any alternative minimum taxes, the Medicare tax on net investment income, state or local or non-U.S. taxes or any U.S. federal tax laws other than those pertaining to income taxation. The discussion assumes that the shares are held as “capital assets” within the meaning of Section 1221 of the Code. We have neither requested nor obtained a written opinion of counsel or a ruling from the IRS with respect to the tax matters discussed below.

As used herein, a “U.S. Holder” means a beneficial owner of shares that is, for U.S. federal income tax purposes, (i) an individual who is a citizen or resident of the United States, (ii) a corporation (or other entity treated as a corporation for these purposes) that is created or organized in or under the laws of the United States, any state thereof or the District of Columbia, (iii) an estate the income of which is subject to U.S. federal income

26

taxation regardless of its source, or (iv) a trust if (x) a court within the United States is able to exercise primary supervision over the administration of the trust, and one or more U.S. persons have the authority to control all substantial decisions of the trust, or (y) it has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person. As used herein, a “Non-U.S. Holder” means a beneficial owner of shares that is neither a U.S. Holder nor a partnership (or other entity treated as a partnership for U.S. federal income tax purposes). If a partnership (or other entity treated as a partnership for U.S. federal income tax purposes) holds shares, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. A partnership holding shares and partners in such partnership should consult their tax advisors about the U.S. federal income tax consequences of a sale of shares for cash pursuant to the Offer.

The Offer will have no U.S. federal income tax consequences to stockholders that do not tender any shares in the Offer.

Each stockholder should consult its own tax advisor as to the particular U.S. federal income tax consequences to such stockholder of tendering shares pursuant to the Offer and the applicability and effect of any state, local or non-U.S. tax laws and other tax consequences with respect to the Offer.

U.S. Federal Income Tax Treatment of U.S. Holders

Characterization of Sale of Shares Pursuant to the Offer. The sale of shares by a stockholder for cash pursuant to the Offer will be a taxable transaction for U.S. federal income tax purposes. The U.S. federal income tax consequences to a U.S. Holder may vary depending upon the U.S. Holder’s particular facts and circumstances. Under Section 302 of the Code, the sale of shares by a stockholder for cash pursuant to the Offer will be treated as a “sale or exchange” of shares for U.S. federal income tax purposes, rather than as a distribution with respect to the shares held by the tendering U.S. Holder, if the sale (i) results in a complete termination of the U.S. Holder’s equity interest in us under Section 302(b)(3) of the Code, (ii) is a “substantially disproportionate” redemption with respect to the U.S. Holder under Section 302(b)(2) of the Code, or (iii) is “not essentially equivalent to a dividend” with respect to the U.S. Holder under Section 302(b)(1) of the Code, each as described below (the “Section 302 Tests”).

Special “constructive ownership” rules will apply in determining whether any of the Section 302 Tests has been satisfied. A U.S. Holder must take into account not only the shares that are actually owned by the U.S. Holder, but also shares that are constructively owned by the U.S. Holder within the meaning of Section 318 of the Code. Very generally, a U.S. Holder may constructively own shares actually owned, and in some cases constructively owned, by certain members of the U.S. Holder’s family and certain entities (such as corporations, partnerships, trusts and estates) in which the U.S. Holder has an equity interest, as well as shares the U.S. Holder has an option to purchase.

The receipt of cash by a U.S. Holder will be a complete termination if either (i) the U.S. Holder owns none of our shares either actually or constructively immediately after the shares are sold pursuant to the Offer, or (ii) the U.S. Holder actually owns none of our shares immediately after the sale of shares pursuant to the Offer and, with respect to shares constructively owned by the U.S. Holder immediately after the Offer, the U.S. Holder is eligible to waive, and effectively waives, constructive ownership of all such shares under procedures described in Section 302(c) of the Code.

The receipt of cash by a U.S. Holder will be “substantially disproportionate” if the percentage of our outstanding shares actually and constructively owned by the U.S. Holder immediately following the sale of shares pursuant to the tender offer is less than 80% of the percentage of the outstanding shares actually and constructively owned by the U.S. Holder immediately before the sale of shares pursuant to the Offer.

Even if the receipt of cash by a U.S. Holder fails to satisfy the complete termination test and the “substantially disproportionate” test, a U.S. Holder may nevertheless satisfy the “not essentially equivalent to a

27

dividend” test if the U.S. Holder’s surrender of shares pursuant to the Offer results in a “meaningful reduction” in the U.S. Holder’s interest in us. Whether the receipt of cash by a U.S. Holder will be “not essentially equivalent to a dividend” will depend upon the U.S. Holder’s particular facts and circumstances. The IRS has indicated in published rulings that even a small reduction in the proportionate interest of a small minority stockholder in a publicly held corporation who exercises no control over corporate affairs may constitute a “meaningful reduction.”

Contemporaneous dispositions or acquisitions of shares by a U.S. Holder or related individuals or entities may be deemed to be part of a single integrated transaction and may be taken into account in determining whether the Section 302 Tests have been satisfied. Each U.S. Holder should be aware that, because proration may occur in the Offer, even if all the shares actually and constructively owned by a stockholder are tendered pursuant to the Offer, fewer than all of these shares may be purchased by us. Thus, proration may affect whether the sale of shares by a stockholder pursuant to the Offer will meet any of the Section 302 Tests. See Section 6 for information regarding an option to make a conditional tender of a minimum number of shares. U.S. Holders should consult their own tax advisors regarding whether to make a conditional tender of a minimum number of shares, and the appropriate calculation thereof.

Further, if other holders exchange a greater percentage of their Shares pursuant to the Offer than a particular U.S. Holder, the U.S. Holder’s proportionate interest in us may increase immediately following the Offer even if that U.S. Holder exchanges Shares for cash pursuant to the Offer and does not (actually or constructively) acquire any other Shares, and that would cause the U.S. Holder not to meet any of the Section 302 Tests.

U.S. Holders should consult their own tax advisors regarding the application of the three Section 302 Tests to their particular facts and circumstances, including the effect of the constructive ownership rules on their sale of shares pursuant to the Offer.

Sale or Exchange Treatment. If any of the above three Section 302 Tests is satisfied, and the sale of the shares is therefore treated as a “sale or exchange” for U.S. federal income tax purposes, the tendering U.S. Holder will recognize gain or loss equal to the difference between the amount of cash received by the U.S. Holder and such holder’s adjusted tax basis in the shares sold pursuant to the Offer. Generally, a U.S. Holder’s adjusted tax basis in the shares will be equal to the cost of the shares to the U.S. Holder. Any gain or loss will be capital gain or loss, and generally will be long-term capital gain or loss if the U.S. Holder’s holding period for the shares that were sold exceeds one year as of the date of the purchase by us pursuant to Offer. Certain noncorporate U.S. Holders (including individuals) are eligible for reduced rates of U.S. federal income tax in respect of long-term capital gain. A U.S. Holder’s ability to deduct capital losses is subject to limitations under the Code. A U.S. Holder must calculate gain or loss separately for each block of shares (generally, shares acquired at the same cost in a single transaction) that we purchase from the U.S. Holder pursuant to the Offer.

Distribution Treatment. If none of the Section 302 Tests are satisfied, the tendering U.S. Holder will be treated as having received a distribution by us with respect to the U.S. Holder’s shares in an amount equal to the cash received by such U.S. Holder pursuant to the Offer. The distribution would be treated as a dividend to the extent of such U.S. Holder’s pro rata share of our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Such a dividend would be taxed in its entirety without a reduction for the U.S. Holder’s adjusted tax basis of the shares exchanged and the adjusted tax basis of such exchanged shares would be added to the adjusted tax basis of the U.S. Holder’s remaining shares, if any. Provided that minimum holding period requirements are met, non-corporate U.S. Holders (including individuals) generally will be subject to U.S. federal income taxation at the reduced rates applicable to long-term capital gains on amounts treated as dividends. The amount of any distribution in excess of our current or accumulated earnings and profits would be treated as a return of the U.S. Holder’s adjusted tax basis in the shares (with a corresponding reduction in such U.S. Holder’s adjusted tax basis until reduced to zero), and then as gain from the sale or exchange of the shares.

28

If a sale of shares by a corporate U.S. Holder is treated as a dividend, the corporate U.S. Holder may be (i) eligible for a dividends-received deduction (subject to applicable exceptions and limitations) and (ii) subject to the “extraordinary dividend” provisions of Section 1059 of the Code. Corporate U.S. Holders should consult their tax advisors regarding (i) whether a dividends-received deduction will be available to them, and (ii) the application of Section 1059 of the Code to the ownership and disposition of their shares.

The determination of whether a corporation has current or accumulated earnings or profits is complex and the legal standards to be applied are subject to uncertainties and ambiguities, including the fact that the treatment of repurchases pursuant to this Offer will itself inform whether we have earnings and profits in excess of the total amount of cash distributed pursuant to the offer. Additionally, whether a corporation has current earnings and profits can be determined only at the end of the taxable year. Accordingly, the extent to which a U.S. Holder will be treated as receiving a dividend if the repurchase of its shares pursuant to the Offer is not entitled to sale or exchange treatment under Section 302 of the Code is unclear.

U.S. Federal Income Tax Treatment of Non-U.S. Holders

Withholding for Non-U.S. Holders. See Section 3 and the discussion below under “Distribution Treatment” with respect to the application of U.S. federal income tax withholding to payments made to Non-U.S. Holders pursuant to the Offer.

Sale or Exchange Treatment. Gain recognized by a Non-U.S. Holder on a sale of shares for cash pursuant to the Offer generally will not be subject to U.S. federal income tax if the sale is treated as a “sale or exchange” pursuant to the Section 302 Tests described above under “U.S. Federal Income Tax Treatment of U.S. Holders” unless (i) such gain is effectively connected with the conduct by such Non-U.S. Holder of a trade or business in the United States (and, if an income tax treaty applies, the gain is generally attributable to a U.S. permanent establishment maintained by such Non-U.S. Holder), (ii) in the case of gain realized by a Non-U.S. Holder that is an individual, such Non-U.S. Holder is present in the United States for 183 days or more in the taxable year of the sale and certain other conditions are met or (iii) the Company is or has been a United States real property holding corporation (“USRPHC”) for U.S. federal income tax purposes and, if the shares are “regularly traded on an established securities market,” such Non-U.S. Holder owned, directly or indirectly, at any time during the five-year period ending on the date of the Offer more than 5% of our shares and such Non-U.S. Holder is not eligible for any treaty exemption. The shares will be considered “regularly traded” if they are traded on an established securities market located in the United States and are regularly quoted by brokers or dealers making a market in the Shares.

With respect to item (iii) above, the Company believes it has been, is, and at the time of the Offer will be, a USRPHC for U.S. federal income tax purposes. In addition we believe that our shares currently should be considered to be regularly traded. Assuming such treatment is respected, the Non-U.S. Holder will be taxable on gain recognized on the disposition of the shares only if the Non-U.S. Holder directly or indirectly (including through the constructive ownership rules described above under U.S. Federal Income Tax Treatment of U.S. Holders—Characterization of Sale of Shares Pursuant to the Offer) holds or has held more than 5% of the shares of the Company at any time during the applicable period described in item (iii) above. On the other hand, if the shares are not “regularly trade on an established securities market” when the Company purchases shares from a Non-U.S. Holder pursuant to the Offer, the Non-U.S. Holder will be taxable on any gain recognized on the disposition of the shares.

If a Non-U.S. Holder were subject to U.S. federal income tax as a result of the Company’s status as a USRPHC, any gain or loss on the disposition of the shares would be taken into account as if it were effectively connected with the conduct by the Non-U.S. Holder of a trade or business within the United States. Any such gain generally would be taxable to the Non-U.S. Holder at the U.S. federal income tax rates applicable to capital gains.

29

To the extent an applicable withholding agent treats a repurchase as a sale of shares for cash rather than a distribution, FIRPTA withholding equal to 15% of the gross amount of the Offer in respect of such shares could apply, regardless of a Non-U.S. Holder’s tax basis in our shares. A Non-U.S. Holder would be entitled to seek a refund of such withheld amounts to the extent the amount of withholding exceeds the Non-U.S. Holder’s U.S. tax liability for the year. As discussed above in Section 3, in order to avoid FIRPTA withholding, a Non-U.S. Holder must submit a FIRPTA Certificate.

Distribution Treatment. If the Non-U.S. Holder does not satisfy any of the Section 302 Tests explained above, the full amount received by the Non-U.S. Holder with respect to the sale of shares to us pursuant to the Offer will be treated as a distribution to the Non-U.S. Holder with respect to the Non-U.S. Holder’s shares. The treatment for U.S. federal income tax purposes of such distribution as a dividend, tax-free return of capital or as gain from the sale of shares will be determined in the manner described above under “U.S. Federal Income Tax Treatment of U.S. Holders.”

If a Non-U.S. Holder tenders shares held in a U.S. brokerage account or otherwise through a U.S. broker, dealer, commercial bank, trust company, or other nominee, such U.S. broker or other nominee will generally be the withholding agent for the payment made to the Non-U.S. Holder pursuant to the Offer. Such U.S. brokers or other nominees may withhold or require certifications in this regard. Non-U.S. Holders tendering shares held through a U.S. broker or other nominee should consult such U.S. broker or other nominee and their own tax advisors to determine the particular withholding procedures that will be applicable to them. Notwithstanding the foregoing, even if a Non-U.S. Holder tenders shares held in its own name as a holder of record and delivers to the Depositary or other applicable tax withholding agent a properly completed IRS Form W-8BEN or W-8BEN-E (or other applicable form) before any payment is made, it is possible that one or more applicable tax withholding agent may withhold 30% of the gross proceeds unless the applicable tax withholding agent determines that a reduced rate under an applicable income tax treaty or exemption from withholding is applicable, regardless of whether the payment is properly exempt from U.S. federal gross income tax under the complete termination, “substantially disproportionate,” or “not essentially equivalent to a dividend” test.

To obtain a reduced rate of withholding under an applicable tax treaty, a Non-U.S. Holder must deliver to the Depositary or other applicable tax withholding agent a properly completed IRS Form W-8BEN or W-8BEN-E (or other applicable form) before the payment is made. To obtain an exemption from withholding on the grounds that the gross proceeds paid pursuant to the Offer are effectively connected with the conduct of a trade or business within the United States, a Non-U.S. Holder must deliver to the Depositary or other applicable tax withholding agent a properly completed IRS Form W-8ECI (or successor form). A Non-U.S. Holder that qualifies for an exemption from withholding on these grounds generally will be required to file a U.S. federal income tax return and generally will be subject to U.S. federal income tax on income derived from the sale of shares pursuant to the Offer in the manner and to the extent as if it were a U.S. Holder, and in the case of a foreign corporation, an additional branch profits tax may be imposed, at a rate of 30% (or a lower rate specified in an applicable income tax treaty), with respect to such income.

A Non-U.S. Holder may be eligible to obtain a refund of all or a portion of any tax withheld if the Non-U.S. Holder (i) meets the complete termination, “substantially disproportionate” or “not essentially equivalent to a dividend” tests described in this Section 14 that would characterize the exchange as a sale (as opposed to a dividend) with respect to which the Non-U.S. Holder is not subject to U.S. federal income tax or (ii) is otherwise able to establish that no tax or a reduced amount of tax is due.

FATCA

Under sections 1471 through 1474 of the Code, commonly referred to as “FATCA,” the regulations promulgated thereunder, official interpretations thereof or any intergovernmental agreement (or guidance thereunder) entered into pursuant thereto, dividends that are paid to “foreign financial institutions” and certain

30

other foreign entities may be subject to withholding at a 30% rate, unless such recipients have provided the withholding agent with certain information with respect to its or such entity’s direct and indirect U.S. owners, and if such recipient is a foreign financial institution, such institution has entered into an agreement with the U.S. government to collect and provide to the U.S. tax authorities information about its accountholders (including certain investors in such institution or entity) or has satisfied the requirements of an applicable intergovernmental agreement.

Non-U.S. Holders are urged to consult their own tax advisors regarding the application of U.S. federal withholding tax to the sale of shares pursuant to the Offer, including the eligibility for withholding tax reductions or exemptions and refund procedures.

Backup Withholding

See Section 3 with respect to the application of the U.S. federal backup withholding tax.

15. Extension of the Tender Offer; Termination; Amendment

Notwithstanding anything to the contrary contained herein, we expressly reserve the right, in our sole discretion, at any time and from time to time, and regardless of whether or not any of the events set forth in Section 7 shall have occurred or shall be deemed by us to have occurred, to extend the period of time during which the Offer is open and thereby delay acceptance for payment of, and payment for, any shares by giving oral or written notice of such extension to the Depositary and making a public announcement of such extension. We also expressly reserve the right, in our sole discretion, to terminate the Offer and not accept for payment or pay for any shares not theretofore accepted for payment or paid for or, subject to applicable law, to postpone payment for shares upon the occurrence of any of the conditions specified in Section 7 hereof by giving oral or written notice of such termination or postponement to the Depositary and making a public announcement of such termination or postponement. Our reservation of the right to delay payment for shares which we have accepted for payment is limited by Rule 13e-4(f)(5) promulgated under the Exchange Act, which requires that we pay the consideration offered or return the shares tendered promptly after termination or withdrawal of a tender offer. Subject to compliance with applicable law, we further reserve the right, in our sole discretion, and regardless of whether any of the events set forth in Section 7 shall have occurred or shall be deemed by us to have occurred, to amend the Offer in any respect, including, without limitation, by decreasing or increasing the consideration offered in the Offer to holders of shares or by decreasing or increasing the number of shares being sought in the Offer. Amendments to the Offer may be made at any time and from time to time effected by public announcement, such announcement, in the case of an extension, to be issued no later than 9:00 a.m., New York City time, on the next business day after the last previously scheduled or announced Expiration Time. Any public announcement made under the Offer will be disseminated promptly to stockholders in a manner reasonably designed to inform stockholders of such change. Without limiting the manner in which we may choose to make a public announcement, except as required by applicable law, we shall have no obligation to publish, advertise or otherwise communicate any such public announcement other than by making a release through Business Wire or another comparable service. In addition, we would file such press release as an exhibit to the Schedule TO.

If we materially change the terms of the Offer or the information concerning the Offer, we will extend the Offer to the extent required by Rules 13e-4(d)(2), 13e-4(e)(3) and 13e-4(f)(1) promulgated under the Exchange Act. These rules and certain related releases and interpretations of the Commission provide that the minimum period during which a tender offer must remain open following material changes in the terms of the Offer or information concerning the Offer (other than a change in price or a change in percentage of securities sought) will depend on the facts and circumstances, including the relative materiality of such terms or information; however, in no event will the Offer remain open for fewer than five business days following such a material change in the terms of, or information concerning, the Offer. If (1)(a) we increase or decrease the price to be paid for shares, (b) decrease the number of shares being sought in the Offer, or (c) increase the number of shares being sought in the Offer by more than 2% of our outstanding shares and (2) the Offer is scheduled to expire at any

31

time earlier than the expiration of a period ending on the tenth business day from, and including, the date on which such notice of an increase or decrease is first published, sent or given to security holders in the manner specified in this Section 15, the Offer will be extended until the expiration of such period of ten business days.

16. Fees and Expenses

Citigroup Global Markets Inc. is acting as Dealer Manager in connection with the Offer and will receive customary fees in connection with this engagement. The Dealer Manager will receive customary compensation for its services, and will be reimbursed for reasonable out-of-pocket expenses incurred in connection with the Offer. We have agreed to indemnify the Dealer Manager against certain liabilities, including certain liabilities under the U.S. federal securities laws. The Dealer Manager may also provide various investment banking and other services to us in the future, for which services they would expect to receive customary compensation from us. The Dealer Manager and its affiliates provide us and entities in which we have an equity interest with borrowing capacity under certain credit facilities. Additionally, in the ordinary course of business, including in its trading and brokerage operations and in a fiduciary capacity, the Dealer Manager and its affiliates in the ordinary course of their respective businesses may purchase and/or sell our securities, including the shares, and may hold positions, both long and short, in our securities, including the shares, for their respective own accounts and for the account of their respective customers. As a result, the Dealer Manager and its affiliates at any time may own certain of our securities, including the shares. In addition, the Dealer Manager and its affiliates may tender shares into the Offer for its own account and for the account of its customers.

We have retained D.F. King & Co., Inc. to act as Information Agent and American Stock Transfer & Trust Company, LLC to act as Depositary in connection with the Offer. The Information Agent may contact holders of shares by mail, facsimile and personal interviews and may request brokers, dealers and other nominee stockholders to forward materials relating to the Offer to beneficial owners. The Information Agent and the Depositary will each receive reasonable and customary compensation for their respective services, will be reimbursed by us for reasonable out-of-pocket expenses and will be indemnified against certain liabilities in connection with the Offer, including certain liabilities under the federal securities laws.

We will not pay any fees or commissions to brokers, dealers or other persons (other than fees to the Dealer Manager and Information Agent as described above) for soliciting tenders of shares pursuant to the Offer. Stockholders holding shares through brokers or banks are urged to consult the brokers or banks to determine whether transaction costs may apply if stockholders tender shares through the brokers or banks and not directly to the Depositary. We will, however, upon request, reimburse brokers, dealers and commercial banks for customary mailing and handling expenses incurred by them in forwarding the Offer and related materials to the beneficial owners of shares held by them as a nominee or in a fiduciary capacity. No broker, dealer, commercial bank or trust company has been authorized to act as our agent or the agent of the Dealer Manager, Information Agent or the Depositary for purposes of the Offer. We will pay or cause to be paid all stock transfer taxes, if any, on our purchase of shares, except as otherwise provided in Instruction 6 in the Letter of Transmittal.

17. Miscellaneous

We are not aware of any U.S. state where the making of the Offer is not in compliance with applicable law. If we become aware of any U.S. state where the making of the Offer or the acceptance of shares pursuant thereto is not in compliance with applicable law, we will make a good faith effort to comply with the applicable law. If, after such good faith effort, we cannot comply with the applicable law, the Offer will not be made to (nor will tenders be accepted from or on behalf of) the holders of shares in such U.S. state. In any jurisdiction where the securities, blue sky or other laws require the Offer to be made by a licensed broker or dealer, the Offer will be deemed to be made on behalf of the Company by one or more registered broker dealers licensed under the laws of that jurisdiction.

Pursuant to Rule 13e-4(c)(2) under the Exchange Act, we have filed with the Commission an Issuer Tender Offer Statement on Schedule TO, which contains additional information with respect to the Offer (the “Schedule

32

TO”). The Schedule TO, including the exhibits and any amendments and supplements thereto, may be examined, and copies may be obtained, at the same places and in the same manner as is set forth in Section 10 with respect to information concerning us.

We have not authorized any person to make any recommendation on behalf of us as to whether you should tender or refrain from tendering your shares in the Offer. We have not authorized any person to give any information or to make any representation in connection with the Offer other than those contained in this document or in the related Letter of Transmittal and the other materials filed as exhibits to the Issuer Tender Offer Statement on Schedule TO-I. We take no responsibility for, and can provide no assurance as to the reliability of, any information or representation, recommendation or information that others may provide you. If given or made, any recommendation or any such information or representation must not be relied upon as having been authorized by us, the Dealer Manager, the Information Agent or the Depositary.

CONDITIONAL TENDER

(See Instruction 12)

A tendering stockholder may condition his or her tender of shares upon the Company purchasing a specified minimum number of the shares tendered, all as described in Section 6 of the Offer to Purchase. Unless at least the minimum number of shares you indicate below are purchased by the Company pursuant to the terms of the Offer, none of the shares tendered by you will be purchased. It is the tendering stockholder’s responsibility to calculate the minimum number of shares that must be purchased if any are purchased, and each stockholder is urged to consult his or her own tax advisor before completing this section. Unless this box has been checked and a minimum specified, your tender will be deemed unconditional.

If, because of proration, the minimum number of shares designated will not be purchased, the Company may accept conditional tenders by random lot, if necessary. However, to be eligible for purchase by random lot, the tendering stockholder must have tendered all of his or her shares and checked this box:

Ladies and Gentlemen:

The undersigned hereby tenders to the Company the above-described shares of common stock of the Company, on the terms and subject to the conditions set forth in the Offer, receipt of which is hereby acknowledged.

Subject to and effective on acceptance for payment of, and payment for, the shares tendered with this Letter of Transmittal in accordance with the terms and subject to the conditions of the Offer, the undersigned hereby sells, assigns and transfers to, or upon the order of, the Company, all right, title and interest in and to all the shares that are being tendered hereby and any and all cash dividends, distributions, rights, other shares or other securities issued or issuable in respect of such shares on or after June 18, 2019 (collectively, “Distributions”). In addition, the undersigned hereby irrevocably constitutes and appoints American Stock Transfer & Trust Company, LLC (the “Depositary”) the true and lawful agent and attorney-in-fact of the undersigned, with full power of substitution (such power of attorney being deemed to be an irrevocable power coupled with an interest), to the full extent of the undersigned’s rights with respect to such shares, to (a) deliver certificates for such shares or transfer ownership of such shares on the account books maintained by the book-entry transfer facility, together, in any such case, with all accompanying evidences of transfer and authenticity to, or upon the order of the Company, (b) present such shares for cancellation and transfer on the Company’s books and (c) receive all benefits and otherwise exercise all rights of beneficial ownership of such shares, all in accordance with the terms and subject to the conditions of the Offer, which agreement will be governed by, and construed in accordance with, the laws of the State of New York.

The undersigned hereby irrevocably appoints each of the designees of the Company the attorneys-in-fact and proxies of the undersigned, each with full power of substitution, to the full extent of such stockholder’s rights with respect to the shares tendered hereby which have been accepted for payment and with respect to any Distributions. The designees of the Company will, with respect to the shares and any associated Distributions for which the appointment is effective, be empowered to exercise all voting and any other rights of such stockholder, as they, in their sole discretion, may deem proper at any annual, special, adjourned or postponed meeting of the Company’s stockholders, by written consent in lieu of any such meeting or otherwise. This proxy and power of attorney shall be irrevocable and coupled with an interest in the tendered shares. Such appointment is effective when, and only to the extent that, the Company accepts the shares tendered with this Letter of Transmittal for payment pursuant to the Offer. Upon the effectiveness of such appointment, without further action, all prior powers of attorney, proxies and consents given by the undersigned with respect to such shares and any associated Distributions will be revoked and no subsequent powers of attorney, proxies, consents or revocations may be given (and, if given, will not be deemed effective). The Company reserves the right to require that, in order for shares to be deemed validly tendered, immediately upon the Company’s acceptance for payment of such shares, the Company must be able to exercise full voting, consent and other rights, to the extent permitted under applicable law, with respect to such shares and any associated Distributions, including voting at any meeting of stockholders or executing a written consent concerning any matter.

The undersigned hereby represents and warrants that the undersigned has full power and authority to tender, sell, assign and transfer the shares tendered hereby and that, when the same are accepted for purchase by the Company, the Company will acquire good title thereto, free and clear of all security interests, liens, restrictions, claims and encumbrances, and the same will not be subject to any adverse claim or right. The undersigned hereby represents and warrants that the undersigned is the registered holder of the shares, or the certificate(s) representing the shares have been endorsed to the undersigned in blank, or the undersigned is a participant in DTC whose name appears on a security position listing as the owner of the shares. The undersigned will, on request by the Depositary or the Company, execute and deliver any additional documents deemed by the Depositary or the Company to be necessary or desirable to complete the sale, assignment and transfer of the shares and any Distributions tendered hereby, all in accordance with the terms of the Offer. In addition, the undersigned shall promptly remit and transfer to the Depositary for the account of the Company any and all Distributions in respect of the shares tendered hereby, accompanied by appropriate documentation of transfer

4

and, pending such remittance or appropriate assurance thereof, the Company shall be entitled to all rights and privileges as owner of any such Distributions and may withhold the entire purchase price or deduct from the purchase price the amount or value thereof, as determined by the Company in its sole discretion.

It is understood that the undersigned will not receive payment for the shares unless and until the shares are accepted for payment and until the certificate(s) representing the shares owned by the undersigned are received by the Depositary at the address set forth below, together with such additional documents as the Depositary may require, or, in the case of shares held in book-entry form, ownership of shares is validly transferred on the account books maintained by DTC, and until the same are processed for payment by the Depositary.

IT IS UNDERSTOOD THAT THE METHOD OF DELIVERY OF THE SHARES, THE CERTIFICATE(S) AND ALL OTHER REQUIRED DOCUMENTS (INCLUDING DELIVERY THROUGH DTC) IS AT THE OPTION AND RISK OF THE UNDERSIGNED AND THAT THE RISK OF LOSS OF SUCH SHARES, CERTIFICATE(S) AND OTHER DOCUMENTS SHALL PASS ONLY AFTER THE DEPOSITARY HAS ACTUALLY RECEIVED THE SHARES OR SHARE CERTIFICATE(S) (INCLUDING, IN THE CASE OF A BOOK-ENTRY TRANSFER, BY BOOK-ENTRY CONFIRMATION (AS DEFINED BELOW)). IF DELIVERY IS BY MAIL, IT IS RECOMMENDED THAT ALL SUCH DOCUMENTS BE SENT BY PROPERLY INSURED REGISTERED MAIL WITH RETURN RECEIPT REQUESTED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

All authority conferred or agreed to be conferred pursuant to this Letter of Transmittal shall be binding on the successors, assigns, heirs, personal representatives, executors, administrators and other legal representatives of the undersigned and shall not be affected by, and shall survive, the death or incapacity of the undersigned. Except as stated in the Offer to Purchase, this tender is irrevocable.

The undersigned understands that the valid tender of shares pursuant to any of the procedures described in Section 3 of the Offer to Purchase and in the instructions to this Letter of Transmittal will constitute a binding agreement between the undersigned and the Company on the terms and subject to the conditions of the Offer.

It is a violation of Rule 14e-4 promulgated under the Exchange Act (as defined in the Offer to Purchase) for a person acting alone or in concert with others, directly or indirectly, to tender shares for such person’s own account unless at the time of tender and at the Expiration Time such person has a “net long position” in (a) the shares that is equal to or greater than the amount tendered and will deliver or cause to be delivered such shares for the purpose of tender to the Company within the period specified in the Offer, or (b) other securities immediately convertible into, exercisable for or exchangeable into shares (“Equivalent Securities”) that is equal to or greater than the amount tendered and, upon the acceptance of such tender, will acquire such shares by conversion, exchange or exercise of such Equivalent Securities to the extent required by the terms of the Offer and will deliver or cause to be delivered such shares so acquired for the purpose of tender to the Company within the period specified in the Offer. Rule 14e-4 also provides a similar restriction applicable to the tender or guarantee of a tender on behalf of another person. A tender of shares made pursuant to any method of delivery set forth in this Letter of Transmittal will constitute the undersigned’s representation and warranty to the Company that (a) the undersigned has a “net long position” in shares or Equivalent Securities being tendered within the meaning of Rule 14e-4, and (b) such tender of shares complies with Rule 14e-4.

The undersigned understands that all shares properly tendered and not properly withdrawn will be purchased at the purchase price, less any applicable withholding taxes and without interest, upon the terms and subject to the conditions of the Offer, including its proration provisions and conditional tender provisions, and that the Company will return at its expense all other shares including shares tendered but not purchased because of proration or conditional tenders, promptly following the Expiration Time.

Unless otherwise indicated herein under “Special Payment Instructions,” please issue the check for payment of the purchase price and/or return any certificates for shares not tendered or accepted for payment in the name(s)

5

of the registered holder(s) appearing under “Description of Shares Tendered.” Similarly, unless otherwise indicated under “Special Delivery Instructions,” please mail the check for payment of the purchase price and/or return any certificates for shares not tendered or accepted for payment (and accompanying documents, as appropriate) to the address(es) of the registered holder(s) appearing under “Description of Shares Tendered.” In the event that both the “Special Delivery Instructions” and the “Special Payment Instructions” are completed, please issue the check for payment of the purchase price and/or return any certificates for shares not tendered or accepted for payment (and any accompanying documents, as appropriate) in the name(s) of, and deliver such check and/or return such certificates (and any accompanying documents, as appropriate) to, the person or persons so indicated. Please credit any shares tendered herewith by book-entry transfer that are not accepted for payment by crediting the account at the book-entry transfer facility designated above. The undersigned recognizes that the Company has no obligation pursuant to the “Special Payment Instructions” to transfer any shares from the name of the registered holder(s) thereof if the Company does not accept for payment any of the shares so tendered.

NOTE: SIGNATURE MUST BE PROVIDED ON PAGE SEVEN BELOW.

THE METHOD OF DELIVERY OF SHARES, THIS LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY TRANSFER FACILITY, IS AT THE SOLE ELECTION AND RISK OF THE TENDERING

8

STOCKHOLDER. SHARES WILL BE DEEMED DELIVERED (AND THE RISK OF LOSS OF SHARE CERTIFICATES WILL PASS) ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY (INCLUDING, IN THE CASE OF A BOOK-ENTRY TRANSFER, BY BOOK-ENTRY CONFIRMATION). IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

Except as specifically provided by the Offer to Purchase, no alternative, conditional or contingent tenders will be accepted. No fractional shares will be purchased. All tendering stockholders, by execution of this Letter of Transmittal, waive any right to receive any notice of the acceptance for payment of their shares.

All questions as to validity, form and eligibility (including time of receipt) of the surrender of any certificates for shares hereunder, including questions as to the proper completion or execution of any Letter of Transmittal, Notice of Guaranteed Delivery or other required documents and as to the proper form for transfer of any certificates, will be determined by the Company in its sole and absolute discretion (which may delegate power in whole or in part to the Depositary) which determination will be final and binding. The Company reserves the absolute right to reject any and all tenders determined by it not to be in proper form or the acceptance for payment of or payment for which may be unlawful. The Company also reserves the absolute right to waive any defect or irregularity in the surrender of any shares or certificates whether or not similar defects or irregularities are waived in the case of any other stockholder. A surrender will not be deemed to have been validly made until all defects and irregularities have been cured or waived. The Company and the Depositary shall make reasonable efforts to notify any person of any defect in any Letter of Transmittal submitted to the Depositary. See Instruction 8 for further information.

3. Inadequate Space. If the space provided in the box entitled “Description of Shares Tendered” in this Letter of Transmittal is inadequate, the certificate numbers and/or the number of shares should be listed on a separate signed schedule attached hereto.

4. Partial Tenders (Not Applicable to Stockholders Who Tender by Book-Entry Transfer). If fewer than all the shares represented by any certificate submitted to the Depositary are to be tendered, fill in the number of shares that are to be tendered in the box entitled “Number of Shares Tendered.” In that case, if any tendered shares are purchased, new certificate(s) for the remainder of the shares that were evidenced by the old certificate(s) will be sent to the registered holder(s), unless otherwise provided in the appropriate box on this Letter of Transmittal, as soon as practicable after the acceptance for payment of, and payment for, the shares tendered herewith. All shares represented by certificates delivered to the Depositary will be deemed to have been tendered unless otherwise indicated.

5. Signatures on Letter of Transmittal, Stock Powers and Endorsements. If this Letter of Transmittal is signed by the registered holder(s) of the shares tendered hereby, the signature(s) must correspond exactly with the name(s) as written on the face of the certificate(s) without any change whatsoever.

If any of the shares tendered hereby are owned of record by two or more joint owners, all such persons must sign this Letter of Transmittal.

If any shares tendered hereby are registered in different names on several certificates, it will be necessary to complete, sign and submit as many separate Letters of Transmittal as there are different registrations of certificates.

If this Letter of Transmittal or any certificate or stock power is signed by a trustee, executor, administrator, guardian, attorney-in-fact, officer of a corporation or other legal entity or other person acting in a fiduciary or representative capacity, he or she should so indicate when signing, and proper evidence satisfactory to the Company of his or her authority to so act must be submitted with this Letter of Transmittal.

9

If this Letter of Transmittal is signed by the registered holder(s) of the shares tendered hereby, no endorsements of certificates or separate stock powers are required unless payment of the purchase price is to be made, or certificates for shares not tendered or accepted for payment are to be issued, to a person other than the registered holder(s). Signatures on any such certificates or stock powers must be guaranteed by an eligible institution.

If this Letter of Transmittal is signed by a person other than the registered holder(s) of the shares tendered hereby, or if payment is to be made or certificate(s) for shares not tendered or not purchased are to be issued to a person other than the registered holder(s), the certificate(s) representing such shares must be properly endorsed for transfer or accompanied by appropriate stock powers, in either case signed exactly as the name(s) of the registered holder(s) appear(s) on the certificates(s). The signature(s) on any such certificate(s) or stock power(s) must be guaranteed by an eligible institution. See Instruction 1.

6. Stock Transfer Taxes. The Company will pay any stock transfer taxes with respect to the transfer and sale of shares to it pursuant to the Offer. If, however, payment of the purchase price is to be made to, or if shares not tendered or accepted for payment are to be registered in the name of, any person(s) other than the registered holder(s), or if shares tendered hereby are registered in the name(s) of any person(s) other than the person(s) signing this Letter of Transmittal, the amount of any stock transfer taxes (whether imposed on the registered holder(s) or such person(s)) payable on account of the transfer to such person(s) will be deducted from the purchase price unless satisfactory evidence of the payment of such taxes or exemption therefrom is submitted with this Letter of Transmittal.

Except as provided in this Instruction 6, it will not be necessary for transfer tax stamps to be affixed to the certificates listed in this Letter of Transmittal.

7. Special Payment and Delivery Instructions. If a check for the purchase price of any shares accepted for payment is to be issued in the name of, and/or certificates for any shares not accepted for payment or not tendered are to be issued in the name of and/or returned to, a person other than the signer of this Letter of Transmittal or if a check is to be sent, and/or such certificates are to be returned, to a person other than the signer of this Letter of Transmittal or to an address other than that shown above, the appropriate boxes on this Letter of Transmittal must be completed and signatures must be guaranteed as described in Instructions 1 and 5.

8. Irregularities. The Company will determine in its sole discretion all questions as to the number of shares to accept, and the validity, eligibility (including time of receipt), and acceptance for payment of any tender of shares. Any such determinations will be final and binding on all parties, subject to a stockholder’s right to challenge our determination in a court of competent jurisdiction. The Company reserves the absolute right to reject any or all tenders of shares it determines not be in proper form or the acceptance of which or payment for which may, in the Company’s opinion, be unlawful. The Company also reserves the absolute right to waive any defect or irregularity in the tender of any particular shares, and the Company’s interpretation of the terms of the Offer, including these instructions, will be final and binding on all parties. No tender of shares will be deemed to be properly made until all defects and irregularities have been cured or waived. Unless waived, any defects or irregularities in connection with tenders must be cured within such time as the Company shall determine. None of the Company, the Depositary, the Information Agent (as defined in the Offer to Purchase) or any other person is or will be obligated to give notice of any defects or irregularities in tenders and none of them will incur any liability for failure to give any such notice.

9. U.S. Federal Backup Withholding Tax. Under the U.S. federal backup withholding tax rules, 24% of the gross proceeds payable to a stockholder or other payee in the Offer must be withheld and remitted to the Internal Revenue Service (the “IRS”), unless the stockholder or other payee provides such person’s taxpayer identification number (“TIN”) (generally an employer identification number or social security number) to the Depositary (and potentially any other applicable tax withholding agent) or other payor and certifies under penalties of perjury that this number is correct or otherwise establishes an exemption. If the Depositary (and/or

10

any other applicable tax withholding agent) or other payor is not provided with the correct TIN or another adequate basis for exemption, the stockholder may be subject to backup withholding tax and may be subject to certain penalties imposed by the IRS. Therefore, each tendering stockholder that is a U.S. Holder (as defined in Section 14 of the Offer to Purchase) should complete and sign the IRS Form W-9 included as a part of the Letter of Transmittal in order to provide the information and certification necessary to avoid the backup withholding tax, unless the stockholder otherwise establishes an exemption from the backup withholding tax to the satisfaction of the Depositary (and/or any other applicable tax withholding agent). The backup withholding tax is not an additional tax, and any amounts withheld under the backup withholding tax rules will be allowed as a refund or credit against a stockholder’s U.S. federal income tax liability provided the required information is timely furnished to the IRS. A U.S. Holder (or other payee) should write “Applied For” in Part I of the attached IRS Form W-9 if such U.S. Holder (or other payee) has not been issued a TIN and has applied for a TIN or intends to apply for a TIN in the near future. If any applicable tax withholding agent is not provided with a TIN prior to payment, such applicable tax withholding agent will withhold 24% on all such payments.

Certain stockholders (including, among others, all corporations and certain Non-U.S. Holders (as defined in Section 14 of the Offer to Purchase)) are not subject to these backup withholding tax rules. In order for a Non-U.S. Holder to qualify as an exempt recipient, that stockholder must submit an IRS Form W-8BEN or W-8BEN-E (or other applicable form), signed under penalties of perjury, attesting to that stockholder’s non-U.S. status. The applicable form can be obtained from the Depositary (and/or other applicable withholding agent). A Non-U.S. Holder that submits a properly completed IRS Form W-8BEN or W-8BEN-E may still be subject to the regular U.S. federal withholding tax on gross proceeds payable to such holder. See Withholding for Non-U.S. Holders and Section 3 and Section 14 of the Offer to Purchase.

Stockholders are urged to consult with their tax advisors regarding possible qualifications for exemption from backup withholding tax and the procedure for obtaining any applicable exemption.

Withholding For Non-U.S. Holders. A payment made to a Non-U.S. Holder pursuant to the Offer will be subject to U.S. federal income and dividend withholding tax unless the Non-U.S. Holder meets the “complete termination,” “substantially disproportionate,” or “not essentially equivalent to a dividend” test described in Section 14 of the Offer to Purchase. If a Non-U.S. Holder tenders shares held in a U.S. brokerage account or otherwise through a U.S. broker, dealer, commercial bank, trust company or other nominee, such U.S. broker or other nominee will generally be the withholding agent for the payment made to the Non-U.S. Holder pursuant to the Offer. Such U.S. brokers or other nominees may withhold or require certifications in this regard. Non-U.S. Holders tendering shares held through a U.S. broker or other nominee should consult such U.S. broker or other nominee and their own tax advisors to determine the particular withholding procedures that will be applicable to them. Notwithstanding the foregoing, even if a Non-U.S. Holder tenders shares held in its own name as a holder of record and delivers to the Depositary (and potentially any other applicable tax withholding agent) a properly completed IRS Form W-8BEN or W-8BEN-E (or other applicable form) before any payment is made, the applicable tax withholding agent may withhold 30% of the gross proceeds unless the applicable tax withholding agent determines that a reduced rate under an applicable income tax treaty or exemption from withholding is applicable, regardless of whether the payment is properly exempt from U.S. federal income tax under the “complete termination,” “substantially disproportionate,” or “not essentially equivalent to a dividend” test.

To obtain a reduced rate of withholding under an applicable income tax treaty, a Non-U.S. Holder must deliver to the (and potentially any other applicable tax withholding agent) a properly completed IRS Form W-8BEN or W-8BEN-E (or other applicable form) before the payment is made. To obtain an exemption from withholding on the grounds that the gross proceeds paid pursuant to the Offer are effectively connected with the conduct of a trade or business within the United States, a Non-U.S. Holder must deliver to the (and potentially any other applicable tax withholding agent) a properly completed IRS Form W-8ECI (or successor form). The applicable form can be obtained from the Depositary (and/or other applicable withholding agent). A Non-U.S. Holder that qualifies for an exemption from withholding on these grounds generally will be required to file a U.S. federal income tax return and generally will be subject to U.S. federal income tax on income derived from the

11

sale of shares pursuant to the Offer in the manner and to the extent described in Section 14 of the Offer to Purchase as if it were a U.S. Holder, and in the case of a foreign corporation, an additional branch profits tax may be imposed at a rate of 30% (or a lower rate specified in an applicable income tax treaty), with respect to such income.

A Non-U.S. Holder may be eligible to obtain a refund of all or a portion of any tax withheld if the Non-U.S. Holder (i) meets the “complete termination,” “substantially disproportionate” or “not essentially equivalent to a dividend” tests described in Section 14 of the Offer to Purchase that would characterize the exchange as a sale (as opposed to a dividend) with respect to which the Non-U.S. Holder is not subject to U.S. federal income tax or (ii) is otherwise able to establish that no tax or a reduced amount of tax is due.

As described in Section 14 of the Offer to Purchase, withholding of 15% of the amount realized will be imposed on a Non-U.S. Holder (including, for this purpose, a foreign partnership) whose ownership of the shares exceeds a certain threshold (the “FIRPTA Withholding”). In order to avoid the FIRPTA Withholding, (1) each U.S. Holder (including a U.S. Holder who is exempt from backup withholding) must submit to the Depositary a properly completed IRS Form W-9, as described above, and (2) each Non-U.S. Holder (including, for this purpose, foreign partnerships) must submit the enclosed FIRPTA Certificate and CHECK BOX 1 certifying that such Non-U.S. Holder’s ownership of the shares has not exceeded the relevant threshold. If a Non-U.S. Holder is unable to make the certification in BOX 1 on the FIRPTA Certificate, such Non-U.S. Holder must submit the enclosed FIRPTA Certificate and CHECK BOX 2 shall take necessary steps to ensure that his, her or its broker or other financial or tax advisor withholds an amount necessary to satisfy any applicable FIRPTA Withholding obligations. By participating in the Offer and CHECKING BOX 2 on the FIRPTA Certificate, you expressly agree to indemnify and hold the Company harmless for any liability related to any FIRPTA Withholding obligations.

NON-U.S. HOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF U.S. FEDERAL INCOME TAX WITHHOLDING AND FIRPTA WITHHOLDING, INCLUDING ELIGIBILITY FOR A WITHHOLDING TAX REDUCTION OR EXEMPTION, AND THE REFUND PROCEDURE.

10. Requests for Assistance or Additional Copies. Questions and requests for assistance or additional copies of the Offer to Purchase, this Letter of Transmittal and the Notice of Guaranteed Delivery may be directed to the Information Agent at its address set forth on the last page of this Letter of Transmittal.

11. Lost, Destroyed or Stolen Certificates. If your certificate(s) for part or all of your shares has been lost, stolen, destroyed or mutilated, you should contact American Stock Transfer & Trust Company, LLC’s Shareholder Service Department at 1-800-937-5449 for information regarding replacement of lost securities. You should also check the box for “Lost Certificates” in the appropriate box on page 2 and promptly send the completed Letter of Transmittal to the Depositary. Upon receipt of your request by phone or Letter of Transmittal, the Depositary will provide you with instructions on how to obtain a replacement certificate. You may be asked to post a bond to secure against the risk that the certificate may be subsequently recirculated. There may be a fee and additional documents may be required to replace lost certificates. This Letter of Transmittal and related documents cannot be processed until the procedures for replacing lost, stolen, destroyed or mutilated certificates have been followed. You are urged to send the properly completed Letter of Transmittal to the Depositary immediately to ensure timely processing of documentation. If you have questions, you may contact the Depositary’s Shareholder Service Department at 1-800-937-5449.

12. Conditional Tenders. As described in Sections 1 and 6 of the Offer to Purchase, stockholders may condition their tenders on all or a minimum number of their tendered shares being purchased.

If you wish to make a conditional tender, you must indicate this in the box captioned “Conditional Tender” in this Letter of Transmittal and, if applicable, in the Notice of Guaranteed Delivery. In the box in this Letter of

12

Transmittal and, if applicable, in the Notice of Guaranteed Delivery, you must calculate and appropriately indicate the minimum number of shares that must be purchased from you if any are to be purchased from you. As discussed in Sections 1 and 5 of the Offer to Purchase, proration may affect whether the Company accepts conditional tenders and may result in shares tendered pursuant to a conditional tender being deemed withdrawn if the required minimum number of shares would not be purchased. If, because of proration, the minimum number of shares that you designate will not be purchased, the Company may accept conditional tenders by random lot, if necessary. However, to be eligible for purchase by random lot, you must have tendered all your shares of common stock and checked the box so indicating. Upon selection by lot, if any, the Company will limit its purchase in each case to the designated minimum number of shares. All tendered shares will be deemed unconditionally tendered unless the “Conditional Tender” box is completed.

The conditional tender alternative is made available so that a stockholder may seek to structure the purchase of shares pursuant to the Offer in such a manner that the purchase will be treated as a sale of such shares by the stockholder, rather than the payment of a dividend to the stockholder, for U.S. federal income tax purposes. It is the tendering stockholder’s responsibility to calculate the minimum number of shares that must be purchased from the stockholder in order for the stockholder to qualify for sale (rather than distribution) treatment for U.S. federal income tax purposes. Each stockholder is urged to consult his or her own tax advisor. No assurances can be provided that a conditional tender will achieve the intended U.S. federal income tax results in all cases. See Section 14 of the Offer to Purchase.

13. Order of Purchase in Event of Proration. As described in Section 1 of the Offer to Purchase, stockholders may designate the order in which their shares are to be purchased in the event of proration. The order of purchase may have an effect on the U.S. federal income tax classification of any gain or loss on the shares purchased. See Section 1 and Section 14 of the Offer to Purchase.

14. Restricted Stock Units. Holders of restricted stock unit awards may not tender such restricted stock units in the Offer unless and until the underlying shares have vested and the restrictions on such awards have lapsed. Once shares underlying the restricted stock unit awards have vested and the restrictions on such awards have lapsed, some or all of such shares may be tendered.

IMPORTANT: THIS LETTER OF TRANSMITTAL, TOGETHER WITH ANY REQUIRED SIGNATURE GUARANTEES, OR, IN THE CASE OF A BOOK-ENTRY TRANSFER, OR AN AGENT’S MESSAGE, TOGETHER WITH CERTIFICATE(S) OR BOOK-ENTRY CONFIRMATION OR A PROPERLY COMPLETED AND DULY EXECUTED NOTICE OF GUARANTEED DELIVERY AND ALL OTHER REQUIRED DOCUMENTS, MUST BE RECEIVED BY THE DEPOSITARY PRIOR TO THE EXPIRATION TIME AND EITHER CERTIFICATES FOR TENDERED SHARES MUST BE RECEIVED BY THE DEPOSITARY OR SHARES MUST BE DELIVERED PURSUANT TO THE PROCEDURES FOR BOOK-ENTRY TRANSFER, IN EACH CASE PRIOR TO THE EXPIRATION TIME, OR THE TENDERING STOCKHOLDER MUST COMPLY WITH THE PROCEDURES FOR GUARANTEED DELIVERY.

IMPORTANT TAX INFORMATION

Under the U.S. federal income tax law, a stockholder whose tendered shares are accepted for payment is required by law to provide the Depositary (and potentially any other applicable tax withholding agent) (as payer) with such stockholder’s correct TIN on the enclosed IRS Form W-9 (or otherwise must indicate on such form that such stockholder is awaiting a TIN, or otherwise establish an exemption from backup withholding). If such stockholder is an individual, the TIN is generally such stockholder’s social security number. If the Depositary (and potentially any other applicable tax withholding agent) is not provided with the correct TIN, the stockholder may be subject to a $50 penalty imposed by the IRS and payments that are made to such stockholder with respect to shares purchased pursuant to the tender offer may be subject to backup withholding tax of 24%.

13

Certain stockholders including, among others, all corporations and certain Non-U.S. Holders, are not subject to these backup withholding requirements. In order for a Non-U.S. Holder to qualify as an exempt recipient, such Non-U.S. Holder must submit an IRS Form W-8BEN or W-8BEN-E (or other applicable IRS Form or substitute forms), signed under penalties of perjury, attesting to such stockholder’s exempt status. An IRS Form W-8BEN or W-8BEN-E (or other applicable IRS Form) can be obtained from the IRS website, at https://www.irs.gov, or the Depositary (and/or any other applicable tax withholding agent). Exempt stockholders (other than Non-U.S. Holders) should furnish their TIN, enter any code(s) that may apply to such stockholder in the “Exemptions” box on the face of the IRS Form W-9, and sign, date and return the IRS Form W-9 to the Depositary (and potentially any other applicable tax withholding agent). See the accompanying instructions to IRS Form W-9 for additional instructions. Stockholders should consult their tax advisors as to qualification for exemption from backup withholding tax and the procedures for obtaining such exemption.

If backup withholding tax applies, the applicable tax withholding agent is required to withhold 24% of any payments made to the stockholder. Backup withholding is not an additional tax. Rather, the U.S. federal income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If backup withholding results in an overpayment of taxes, a refund may be obtained, provided the required information is furnished to the IRS on a timely basis.

Purpose of IRS Form W-9

To prevent backup withholding tax on payments that are made to a stockholder with respect to shares purchased pursuant to the Offer, the stockholder is required to notify the Depositary and any other applicable tax withholding agent of such stockholder’s correct TIN by completing the enclosed IRS Form W-9 certifying that (a) the TIN provided on IRS Form W-9 is correct (or that such stockholder is awaiting a TIN) and (b) that (i) such stockholder has not been notified by the IRS that such stockholder is subject to backup withholding tax as a result of a failure to report all interest or dividends or (ii) the IRS has notified such stockholder that such stockholder is no longer subject to backup withholding tax.

What Number to Give the Depositary (and Potentially Any Other Applicable Tax Withholding Agent)

The stockholder is required to give the Depositary (and potentially any other applicable tax withholding agent) the TIN of the record holder of the shares tendered hereby. If the shares are in more than one name or are not in the name of the actual owner, consult the enclosed instructions to IRS Form W-9 for additional guidance on which number to report. If the tendering stockholder has not been issued a TIN and has applied for a number or intends to apply for a number in the near future, the stockholder should write “Applied For” in Part I, and sign and date the IRS Form W-9. If “Applied For” is written in Part I and the Depositary (and potentially any other applicable tax withholding agent) is not provided with a TIN by the time for payment, the applicable tax withholding agent will withhold 24% of all payments of the purchase price to such stockholder until a TIN is provided.

Under penalties of perjury, I certify that:

Certification instructions. You must cross out item 2 above if you have been notified by the IRS that you are currently subject to backup withholding because you have failed to report all interest and dividends on your tax return. For real estate transactions, item 2 does not apply. For mortgage interest paid, acquisition or abandonment of secured property, cancellation of debt, contributions to an individual retirement arrangement (IRA), and generally, payments other than interest and dividends, you are not required to sign the certification, but you must provide your correct TIN. See the instructions for Part II, later.

Privacy Act Notice

Section 6109 of the Internal Revenue Code requires you to provide your correct TIN to persons (including federal agencies) who are required to file information returns with the IRS to report interest, dividends, or certain other income paid to you; mortgage interest you paid; the acquisition or abandonment of secured property; the cancellation of debt; or contributions you made to an IRA, Archer MSA, or HSA. The person collecting this form uses the information on the form to file information returns with the IRS, reporting the above information. Routine uses of this information include giving it to the Department of Justice for civil and criminal litigation and to cities, states, the District of Columbia, and U.S. commonwealths and possessions for use in administering their laws. The information also may be disclosed to other countries under a treaty, to federal and state agencies to enforce civil and criminal laws, or to federal law enforcement and intelligence agencies to combat terrorism. You must provide your TIN whether or not you are required to file a tax return. Under section 3406, payers must generally withhold a percentage of taxable interest, dividend, and certain other payments to a payee who does not give a TIN to the payer. Certain penalties may also apply for providing false or fraudulent information.

The Registered Holder named below understands that this certification may be disclosed to the Internal Revenue Service and that any false statement contained herein could be punished by fine, imprisonment or both.

Offer to Purchase for Cash

up to 2,666,666 Shares of its Common Stock

at a Purchase Price of $15.00 per Share

June 18, 2019

To Brokers, Dealers, Commercial Banks,

Trust Companies and Other Nominees:

We have been appointed by Riviera Resources, Inc., a Delaware corporation (the “Company”), to act as Information Agent in connection with the Company’s offer to purchase for cash up to 2,666,666 shares of its common stock, par value $0.01 per share (the “shares”), at a price of $15.00 per share, without interest, upon the terms and subject to the conditions set forth in the Offer to Purchase dated June 18, 2019 (the “Offer to Purchase”) and the related Letter of Transmittal (the “Letter of Transmittal,” and together with the Offer to Purchase, as they may be amended or supplemented from time to time, the “Offer”). Please furnish copies of the enclosed materials to those of your clients for whom you hold shares registered in your name or in the name of your nominee.

For your information, and for forwarding to those of your clients for whom you hold shares registered in your name or in the name of your nominee, we are enclosing the following documents:

The Offer is not conditioned upon any minimum number of shares being tendered. The Offer is, however, subject to a number of terms and conditions. See Section 7 of the Offer to Purchase. Please see Section 14 of the Offer to Purchase for a summary of material United States federal income tax consequences to stockholders of an exchange of shares for cash pursuant to the Offer, including with respect to withholding requirements.

Your prompt action is requested. We urge you to contact your clients as promptly as possible. Please note that the Offer, proration period and withdrawal rights will expire at 11:59 p.m., New York City time, on Tuesday, July 16, 2019, unless the Offer is extended or terminated. Under no circumstances will interest be paid on the purchase price of the shares regardless of any extension of, or amendment to, the Offer or any delay in paying for such shares.

For shares to be tendered validly pursuant to the Offer:

Although the Company’s Board of Directors has authorized the Offer, none of the Board of Directors, the Company, the Dealer Manager, the Information Agent or the Depositary, or any of our or their affiliates, has made, and they are not making, any recommendation to your clients as to whether they should tender or refrain from tendering their shares. The Company has not authorized any person to make any such recommendation. Your clients must make their own decision as to whether to tender their shares and, if so, how many shares to tender. In doing so, your clients should read carefully the information in, or incorporated by reference in, the Offer to Purchase and in the Letter of Transmittal, including the purpose and effects of the Offer. See Section 2 of the Offer to Purchase. Your clients are urged to discuss their decision with their own tax advisors, financial advisors and/or brokers.

The Company’s directors, executive officers and affiliates are entitled to participate in the Offer on the same basis as all other stockholders. We do not know whether or to what extent our directors or executive officers will participate in the Offer. In addition, certain funds affiliated with Fir Tree Capital Management LP, Elliott Associates, L.P., York Capital Management, L.P. and P. Schoenfeld Asset Management LP, which are affiliated with certain members of the Company’s Board of Directors (the “Affiliated Holders”) are also entitled to participate in the Offer on the same basis as all other stockholders. The Affiliated Holders have informed us that they may tender shares that they beneficially own in the Offer, however, we do not know whether they will tender any, some or all of their shares in the Offer. The Affiliated Holders collectively held 40,518,819 shares, or approximately 63.7% of the issued and outstanding common stock as of June 14, 2019.

The Company will not pay any fees or commissions to brokers, dealers or other persons (other than fees to the Dealer Manager, the Information Agent and the Depositary, as described in the Offer to Purchase) for soliciting tenders of shares pursuant to the Offer. However, the Company will, on request, reimburse you for customary mailing and handling expenses incurred by you in forwarding copies of the enclosed Offer and related materials to your clients. The Company will pay or cause to be paid all stock transfer taxes, if any, payable on the transfer to it of shares purchased pursuant to the Offer, except as otherwise provided in the Offer to Purchase (see Section 5 of the Offer to Purchase).

The Offer is not being made to, nor will tenders be accepted from or on behalf of, stockholders in any jurisdiction in which the making or acceptance of offers to sell shares would not be in compliance with the laws of that jurisdiction. If the Company becomes aware of any such jurisdiction where the making of the Offer or the acceptance of shares pursuant to the Offer is not in compliance with applicable law, the Company will make a good faith effort to comply with the applicable law. If, after such good faith effort, the Company cannot comply with the applicable law, the Offer will not be made to (nor will tenders be accepted from or on behalf of) the stockholders residing in such jurisdiction. In any jurisdiction where the securities, blue sky or other laws require the Offer to be made by a licensed broker or dealer, the Offer will be deemed to be made on the Company’s behalf by the Dealer Manager, or by one or more registered brokers or dealers licensed under the laws of that jurisdiction.

Very truly yours,

D.F. King & Co., Inc.

RIVIERA RESOURCES, INC.

Offer to Purchase for Cash

up to 2,666,666 Shares of its Common Stock

at a Purchase Price of $15.00 per Share

June 18, 2019

To Our Clients:

Enclosed for your consideration are the Offer to Purchase, dated June 18, 2019 (the “Offer to Purchase”) and the related Letter of Transmittal (the “Letter of Transmittal” and, together with the Offer to Purchase, as they may be amended or supplemented from time to time, the “Offer”), by Riviera Resources, Inc., a Delaware corporation (the “Company”), to purchase for cash up to 2,666,666 shares of its common stock, par value $0.01 per share (the “shares”), at a price of $15.00 per share, without interest, upon the terms and subject to the conditions set forth in the Offer.

All shares properly tendered before the Expiration Time and not properly withdrawn will be purchased by the Company at the purchase price of $15.00 per share, less any applicable withholding taxes and without interest, on the terms and subject to the conditions of the Offer, including the proration provisions and conditional tender provisions. The Company reserves the right, in its sole discretion, to purchase more than 2,666,666 shares in the Offer, subject to applicable law. Shares not purchased because of proration provisions or conditional tenders will be returned to the tendering stockholders at the Company’s expense promptly after the expiration of the Offer. See Section 1 and Section 3 of the Offer to Purchase.

If the number of shares properly tendered is less than or equal to 2,666,666 shares (or such greater number of shares as the Company may elect to purchase pursuant to the Offer, subject to applicable law), the Company will, on the terms and subject to the conditions of the Offer, purchase all shares so tendered.

On the terms and subject to the conditions of the Offer, if at the expiration of the Offer more than 2,666,666 shares (or such greater number of shares as the Company may elect to purchase, subject to applicable law) are properly tendered, the Company will buy shares first, on a pro rata basis from all stockholders who properly tender shares, subject to any conditional tenders, and second, if necessary to permit the Company to purchase 2,666,666 shares (or any such greater number of shares as the Company may elect to purchase, subject to applicable law), from holders who have tendered shares subject to the condition that a specified minimum number of the holder’s shares are purchased in the Offer, as described in Section 6 of the Offer to Purchase (for which the condition was not initially satisfied, and provided the holders tendered all of their shares) by random lot, to the extent feasible. See Section 1, Section 3 and Section 6 of the Offer to Purchase.

We are the owner of record (directly or indirectly) of shares held for your account. As such, we are the only ones who can tender your shares, and then only pursuant to your instructions. We are sending you the Letter of Transmittal for your information only; you cannot use it to tender shares we hold for your account.

Please instruct us, by completing the attached Instruction Form, as to whether you wish us to tender all or any portion of the shares we hold for your account on the terms and subject to the conditions of the Offer.

Please note the following:

1. You may tender your shares at a price of $15.00 per share, as indicated in the attached Instruction Form, without interest.

2. You should consult with your broker or other financial or tax advisor on the possibility of designating the priority in which your shares will be purchased in the event of proration.

3. The Offer is not conditioned upon any minimum number of shares being tendered. The Offer is, however, subject to a number of terms and conditions. See Section 7 of the Offer to Purchase.

4. The Offer, proration period and withdrawal rights will expire at 11:59 p.m., New York City time, on Tuesday, July 16, 2019, unless the Offer is extended or terminated.

5. The Offer is for 2,666,666 shares, constituting approximately 4.2% of the total number of outstanding shares of the Company’s common stock as of June 14, 2019.

6. Tendering stockholders who are registered stockholders or who tender their shares directly to American Stock Transfer & Trust Company, LLC will not be obligated to pay any brokerage commissions or fees to the Company, solicitation fees, or, except as set forth in the Offer to Purchase and the Letter of Transmittal, stock transfer taxes on the Company’s purchase of shares under the Offer.

7. If you wish to make your tender conditional upon the purchase of all shares tendered or upon the Company’s purchase of a specified minimum number of the shares that you tender, you may elect to do so and may thereby avoid possible proration of your tender. The Company’s purchase of shares from all tenders that are so conditioned, to the extent necessary, will be determined by random lot. To elect such a condition, complete the section captioned “Conditional Tender” in the attached Instruction Form.

8. Any tendering stockholder or other payee who is a United States Holder (as defined in Section 14 of the Offer to Purchase) and who fails to complete, sign and return to the Depositary the Form W-9 included with the Letter of Transmittal (or such other Internal Revenue Service form as may be applicable) may be subject to United States federal income tax backup withholding of 24% of the gross proceeds paid to the United States Holder or other payee pursuant to the Offer, unless such holder establishes that such holder is exempt from backup withholding. In order to avoid backup withholding, any tendering stockholder who is a Non-United States Holder (as defined in Section 14 of the Offer to Purchase) must file an appropriate IRS Form W-8, attesting to such stockholder’s exemption from backup withholding. The form can be obtained from the IRS website at www.irs.gov. See Sections 3 and 14 of the Offer to Purchase.

9. As described in Section 14 of the Offer to Purchase, withholding of 15% of the amount realized will be imposed on a Non-U.S. Holder (including, for this purpose, a foreign partnership) whose ownership of the shares exceeds a certain threshold (the “FIRPTA Withholding”). In order to avoid the FIRPTA Withholding, (1) each U.S. Holder (including a U.S. Holder who is exempt from backup withholding) must submit to the Depositary a properly completed Form W-9 as described above, and (2) each Non-U.S. Holder (including, for this purpose, foreign partnerships) must submit the enclosed FIRPTA Certificate and CHECK BOX 1 certifying that such Non-U.S. Holder’s ownership of the shares has not exceeded the requisite threshold. If a Non-U.S. Holder is unable to make the certification in BOX 1 on the FIRPTA Certificate, such Non-U.S. Holder must submit the enclosed FIRPTA Certificate and CHECK BOX 2 certifying that such Non-U.S. Holder shall take necessary steps to ensure that his, her or its broker or other financial or tax advisor withholds, and promptly pays over, an amount necessary to satisfy any applicable FIRPTA Withholding obligations. By participating in the Offer and CHECKING BOX 2 on the FIRPTA Certificate, you expressly agree to indemnify and hold the Company harmless for any liability related to any FIRPTA Withholding obligations.

2

If any tendered shares are not purchased, or if less than all shares evidenced by a shareholder’s certificates are tendered, certificates for unpurchased shares will be returned promptly after the expiration or termination of the Offer or the valid withdrawal of the shares, or, in the case of shares tendered by book-entry transfer at DTC, the shares will be credited to the appropriate account maintained by the tendering shareholder at DTC, in each case at the Company’s expense. The Company also expressly reserves the right, in its sole discretion, to purchase additional shares subject to applicable legal and regulatory requirements. See Section 1 of the Offer to Purchase.

If you wish to have us tender all or any portion of your shares, please so instruct us by completing, executing, detaching and returning to us the attached Instruction Form. An envelope to return your Instruction Form to us is enclosed.

If you authorize us to tender your shares, we will tender all your shares unless you specify otherwise on the attached Instruction Form.

Your prompt action is requested. Your Instruction Form should be forwarded to us in ample time to permit us to submit a tender on your behalf prior to the Expiration Time. Please note that, unless the Company has already accepted your tendered shares for payment, you may withdraw your tendered shares at any time after 11:59 p.m. New York City time, on Tuesday, August 13, 2019, the 40^th business day following the commencement of the Offer.

The Offer is being made solely under the Offer to Purchase and the related Letter of Transmittal and is being made to all record holders of the shares. The Offer is not being made to, nor will tenders be accepted from or on behalf of, stockholders in any jurisdiction in which the making or acceptance of offers to sell shares would not be in compliance with the laws of that jurisdiction. If the Company becomes aware of any such jurisdiction where the making of the Offer or the acceptance of shares pursuant to the Offer is not in compliance with applicable law, the Company will make a good faith effort to comply with the applicable law. If, after such good faith effort, the Company cannot comply with the applicable law, the Offer will not be made to (nor will tenders be accepted from or on behalf of) the stockholders residing in such jurisdiction. In any jurisdiction where the securities, blue sky or other laws require the Offer to be made by a licensed broker or dealer, the Offer will be deemed to be made on the Company’s behalf by the Dealer Manager, or by one or more registered brokers or dealers licensed under the laws of that jurisdiction.

Although the Company’s Board of Directors has authorized the Offer, none of the Board of Directors, the Company, the Dealer Manager, the Information Agent or the Depositary, or any of our or their affiliates, has made, and they are not making, any recommendation to you as to whether you should tender or refrain from tendering your shares. The Company has not authorized any person to make any such recommendation. You must make your own decision as to whether to tender any of your shares and, if so, how many shares to tender. In doing so, you should read carefully the information in, or incorporated by reference in, the Offer, including the purpose and effects of the Offer. You are urged to discuss your decision with your own tax advisor, financial advisor and/or broker.

The Company’s directors, executive officers and affiliates are entitled to participate in the Offer on the same basis as all other stockholders. We do not know whether or to what extent our directors or executive officers will participate in the Offer. In addition, certain funds affiliated with Fir Tree Capital Management LP, Elliott Associates, L.P., York Capital Management, L.P. and P. Schoenfeld Asset Management LP, which are affiliated with certain members of the Company’s Board of Directors (the “Affiliated Holders”) are also entitled to participate in the Offer on the same basis as all other stockholders. We do not know whether or to what extent the Affiliated Holders will participate in the Offer. The Affiliated Holders collectively held 40,518,819 shares, or approximately 63.7% of the issued and outstanding common stock as of June 14, 2019.

Unless at least the minimum number of shares you indicate below is purchased by the Company pursuant to the terms of the Offer, none of the shares tendered by you will be purchased. It is the tendering stockholder’s responsibility to calculate the minimum number of shares that must be purchased from the stockholder in order for the stockholder to qualify for sale or exchange (rather than distribution) treatment for United States federal income tax purposes. Stockholders are urged to consult with their own tax advisors before completing this section. No assurances can be provided that a conditional tender will achieve the intended United States federal income tax result for any stockholder tendering shares. Unless this box has been checked and a minimum number of shares specified, your tender will be deemed unconditional:

If, because of proration, the minimum number of shares designated will not be purchased, the Company may accept conditional tenders by random lot, if necessary. However, to be eligible for purchase by random lot, the tendering stockholder must have tendered all of his or her shares and checked this box:

RIVIERA RESOURCES, INC.

Notice of Offer to Purchase for Cash

up to 2,666,666 Shares of its Common Stock

at a Purchase Price of $15.00 per Share

Riviera Resources, Inc., a Delaware corporation (the “Company”), is offering to purchase for cash up to 2,666,666 shares of its common stock, par value $0.01 per share (the “shares”), at a price of $15.00 per share, without interest, upon the terms and subject to the conditions set forth in the Offer to Purchase dated June 18, 2019 (the “Offer to Purchase”) and the related Letter of Transmittal (the “Letter of Transmittal,” and together with the Offer to Purchase, as they may be amended or supplemented from time to time, the “Offer”).

The Offer is not conditioned upon any minimum number of shares being tendered. The Offer is, however, subject to a number of other terms and conditions as specified in the Offer to Purchase.

Although the Company’s Board of Directors has authorized the Offer, none of the Board of Directors, the Company, the Dealer Manager, the Information Agent (as defined below) or the Depositary, nor any of their respective affiliates, has made, and they are not making, any recommendation to the Company’s stockholders as to whether to tender or refrain from tendering their shares. The Company has not authorized any person to make any such recommendation. Stockholders must make their own decision as to whether to tender their shares and, if so, how many shares to tender. In doing so, stockholders should read carefully the information in, or incorporated by reference in, the Offer, including the purpose and effects of the Offer. Stockholders are urged to discuss their decision with their own tax advisors, financial advisors and/or brokers.

The Company’s Board of Directors believes that the Offer represents a prudent use of the Company’s financial resources in light of its business profile, assets, anticipated future performance and financial condition. As of June 15, 2019, the Company had approximately $74.6 million in cash and cash equivalents. The purpose of the Offer is to return cash to the Company’s stockholders by providing them with the opportunity to tender all or a portion of their shares and thereby receive a return of some or all of their investment if they so elect. In addition, if the Company completes the Offer, stockholders who do not participate in the Offer or otherwise sell their shares of our common stock will automatically increase their relative percentage ownership interest in the Company and its future operations.

The Company will purchase at $15.00 per share up to 2,666,666 shares properly tendered, and not properly withdrawn, prior to the Expiration Time (as defined below), upon the terms and subject to the conditions of the Offer, including the proration and conditional tender provisions (as described in the Offer to Purchase). Under no circumstances will the Company pay interest on the purchase price for the shares, regardless of any delay in making payment. The Company reserves the right, in its sole discretion, to purchase more than 2,666,666 shares under the Offer, subject to applicable law.

The term “Expiration Time” means 11:59 p.m., New York City time, on Tuesday, July 16, 2019, unless the Company, in its sole discretion, shall have extended the period of time during which the Offer will remain open, in which event the term “Expiration Time” shall refer to the latest time and date at which the Offer, as so extended by the Company, shall expire.

As of June 14, 2019, there were 63,621,542 shares outstanding. Assuming that the Offer is fully subscribed, the number of shares that will be purchased under the Offer is 2,666,666 shares, or approximately 4.2% of the shares outstanding as of June 14, 2019.

The Company’s directors, executive officers and affiliates and certain of our stockholders who are affiliated with certain members of the Company’s Board of Directors (the “Affiliated Holders”) are entitled to participate in the Offer on the same basis as all other stockholders. We do not know whether or to what extent the Company’s directors, executive officers and affiliates and the Affiliated Holders will participate in the Offer. The Affiliated Holders collectively beneficially owned 40,518,819 shares, or approximately 63.7% of the issued and outstanding common stock as of June 14, 2019.

Upon the terms and subject to the conditions of the Offer, if more than 2,666,666 shares (or such greater number of shares as the Company may elect to purchase, subject to applicable law) have been properly tendered and not properly withdrawn prior to the Expiration Time, the Company will purchase properly tendered shares in the following order of priority:

If any tendered shares are not purchased, or if less than all shares evidenced by a shareholder’s certificates are tendered, certificates for unpurchased shares will be returned promptly after the expiration or termination of the Offer or the valid withdrawal of the shares, or, in the case of shares tendered by book-entry transfer at DTC, the shares will be credited to the appropriate account maintained by the tendering shareholder at DTC, in each case at the Company’s expense.

Stockholders wishing to tender their shares must follow the procedures set forth in Section 3 of the Offer to Purchase and in the Letter of Transmittal. Stockholders wishing to tender their shares but who are unable to deliver them physically or by book-entry transfer prior to the Expiration Time, or who are unable to make delivery of all required documents to the Depositary prior to the Expiration Time, may tender their shares by complying with the procedures set forth in Section 3 of the Offer to Purchase for tendering by Notice of Guaranteed Delivery.

The proration period is the period for accepting shares on a pro rata basis in the event that the Offer is oversubscribed. The proration period will expire at the Expiration Time. If proration of tendered shares is required, we will determine the proration factor promptly following the Expiration Time.

2

For purposes of the Offer, the Company will be deemed to have accepted for payment, subject to the proration and conditional tender provisions of the Offer, shares that are properly tendered and not properly withdrawn, only when, as and if the Company gives oral or written notice to American Stock Transfer & Trust Company, LLC (the “Depositary”) of its acceptance of the shares for payment pursuant to the Offer.

Upon the terms and subject to the conditions of the Offer, the Company will accept for payment and pay the Purchase Price per share for all of the shares accepted for payment pursuant to the Offer promptly after the Expiration Time. In all cases, payment for shares tendered and accepted for payment pursuant to the Offer will be made promptly, taking into account any time necessary to determine any proration, but only after timely receipt by the Depositary of (1) certificates for shares, or a timely book-entry confirmation of the deposit of shares into the Depositary’s account at DTC (as defined in the Offer to Purchase), (2) a validly completed and duly executed Letter of Transmittal including any required signature guarantees, or, in the case of a book-entry transfer, an agent’s message and (3) any other required documents.

The Company expressly reserves the right, in its sole discretion and subject to applicable law, at any time and from time to time, and regardless of whether or not any of the conditions to the Offer set forth in Section 7 of the Offer to Purchase have occurred or are deemed by the Company to have occurred, to extend the period of time the Offer is open and delay acceptance for payment of, and payment for, any shares by giving oral or written notice of such extension to the Depositary and making a public announcement of such extension no later than 9:00 a.m., New York City time, on the next business day after the last previously scheduled Expiration Time. In the event of an extension, the term “Expiration Time” will refer to the latest time and date at which the Offer, as extended by the Company, will expire. During any such extension, all shares previously tendered and not properly withdrawn will remain subject to the Offer and to the right of a tendering shareholder to withdraw such shareholder’s shares.

The Company also expressly reserves the right, in its sole discretion and subject to applicable law regardless of whether any of the circumstances described in the Offer to Purchase shall have occurred or shall be deemed by the Company to have occurred, to amend the Offer in any respect, including without limitation by increasing or decreasing the consideration offered. The Company further expressly reserves the right, in its sole discretion, to terminate the Offer and reject for payment and not pay for any shares not theretofore accepted for payment or paid for, subject to applicable law, or to postpone payment for shares, upon the occurrence of any of the conditions to the Offer specified in Section 7 of the Offer to Purchase. The Company will give oral or written notice of such amendment, termination or postponement to the Depositary and will make a public announcement of such amendment, termination or postponement of the Offer in accordance with applicable law. The Company’s reservation of the right to delay payment for shares that it has accepted for payment is limited by Rule 13e-4(f)(5) and Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which requires that the Company must pay the consideration offered or return the shares tendered promptly after termination or withdrawal of the Offer.

Shares tendered in the Offer may be withdrawn at any time prior to the Expiration Time. In addition, unless the Company has already accepted such tendered shares for payment, stockholders may withdraw their tendered shares at any time after 11:59 p.m., New York City time, on Tuesday, August 13, 2019, the 40^th business day following the commencement of the Offer. Except as otherwise provided in the Offer to Purchase, tenders of shares pursuant to the Offer are irrevocable. For a withdrawal to be effective, a written or facsimile notice of withdrawal must be received in a timely manner by the Depositary at its address set forth on the back cover page of the Offer to Purchase, and any notice of withdrawal must specify the name of the tendering shareholder, the number of shares to be withdrawn and the name of the registered holder of the shares to be withdrawn, if different from the person who tendered the shares. If the certificates for shares to be withdrawn have been delivered or otherwise identified to the Depositary, then, before the release of those certificates, the tendering shareholder also must submit the serial numbers shown on those particular certificates for shares to be withdrawn and, unless an Eligible Institution (as defined in the Offer to Purchase) has tendered those shares, the signature(s) on the notice of withdrawal must be guaranteed by an Eligible Institution. If shares have been tendered pursuant

3

to the procedures for book-entry transfer described in Section 3 of the Offer to Purchase, the notice of withdrawal also must specify the name and the number of the account at DTC to be credited with the withdrawn shares and must otherwise comply with DTC’s procedures.

All questions as to the form and validity, including the time of receipt, of any notice of withdrawal will be determined by the Company, in its sole discretion, and will be final and binding on all parties absent a finding to the contrary by a court of competent jurisdiction. The Company reserves the absolute right to waive any defect or irregularity in the notice of withdrawal or method of withdrawal of shares by any shareholder, whether or not the Company waives similar defects or irregularities in the case of any other shareholder. None of the Company, the Dealer Manager, the Depositary, the Information Agent or any other person will be obligated to give notice of any defects or irregularities in any notice of withdrawal, nor will any of them incur liability for failure to give any such notice.

Generally, United States stockholders will be subject to United States federal income taxation when they receive cash from the Company in exchange for the shares they tender. Their receipt of cash for tendered shares will generally be treated as either (1) consideration received in a sale or exchange or (2) a distribution with respect to such shares. All stockholders should read carefully the Offer to Purchase for additional information regarding certain tax issues and should consult their own tax advisor regarding the tax consequences of the Offer.

The Offer to Purchase and the Letter of Transmittal contain important information that stockholders should read carefully before they make any decision with respect to the Offer. Copies of the Offer to Purchase and the related Letter of Transmittal will be mailed to record holders of Shares whose names appear on the Company’s stockholder list and will be furnished to brokers, dealers, commercial banks, trust companies and similar persons whose names, or the names of whose nominees, appear on the stockholder list or, if applicable, who are listed as participants in a clearing agency’s security position listing for subsequent transmittal to beneficial owners of shares. Persons who hold vested rights to purchase or otherwise acquire shares will be provided a copy of the Offer to Purchase and the related Letter of Transmittal upon request to the Information Agent at the telephone numbers and address set forth below. Such persons should read the Offer to Purchase for further information regarding how they can participate in the Offer.

The information required to be disclosed by Rule 13e-4(d)(1) under the Exchange Act is contained in the Offer to Purchase and is incorporated herein by reference.

Please direct any questions or requests for assistance to D.F. King & Co., Inc. (the “Information Agent”) or Citigroup Global Markets Inc. (the “Dealer Manager”) at their respective telephone numbers and addresses set forth below. Please direct requests for copies of the Offer to Purchase, the Letter of Transmittal or the Notice of Guaranteed Delivery to the Information Agent at the telephone numbers and address set forth below.

RIVIERA RESOURCES ANNOUNCES COMMENCEMENT OF TENDER OFFER TO PURCHASE UP TO 2,666,666 SHARES OF ITS COMMON STOCK AT A PURCHASE PRICE OF $15.00 PER SHARE

HOUSTON, June 18, 2019 (GLOBE NEWSWIRE) – Riviera Resources, Inc. (OTCQX: RVRA) (“Riviera” or the “Company”) today announced that it is commencing a tender offer to purchase for cash up to 2,666,666 shares of its common stock (the “shares”) at a purchase price of $15.00 per share.
