Subject to, and effective upon, acceptance for payment of and payment for Shares validly tendered herewith 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, Purchaser all right, title and interest in, to and under all of the Shares that are being tendered hereby (and any and all other Shares or other securities or rights issued or issuable in respect of such Shares) and irrevocably appoints the Tender Offer Agent (or any other entity designated by Purchaser) and its directors, officers, employees and agents (and each and any of the foregoing) as the true and lawful agents and attorneys-in-fact (in each case, acting individually or with one or much such other agents or attorneys-in-fact) of the undersigned with respect to such Shares (and any and all other Shares or securities or rights issued or issuable in respect of such Shares), with full power of substitution and re-substitution (such power of attorney being deemed to be an irrevocable power coupled with an interest), to (a) deliver certificates representing such Shares (and any such other Shares or securities or rights), or transfer ownership of such Shares (and any and all other Shares or securities or rights issued or issuable in respect of such Shares) on the account books maintained by DTC, together in either such case with all accompanying evidences of transfer and authenticity, to or upon the order of Purchaser upon receipt by the Tender Offer Agent, as the undersigned’s agent, of the Offer Consideration (adjusted, if appropriate, as provided in the Offer to Purchase), (b) present such Shares (and any such other Shares or securities or rights) for registration and transfer on the books of the Company, (c) receive all benefits and otherwise exercise all rights of beneficial ownership of such Shares (and any such other Shares or securities or rights), all in accordance with the terms of the Offer, and (d) complete and execute any and all form(s) of transfer and other document(s) as may be necessary or required, at the discretion of such attorney-in-fact, in order to transfer those Shares validly tendered and not validly withdrawn, into Purchaser’s name or into the name of such other person(s) as Purchaser may direct, and to deliver such form(s) of transfer and other document(s) as may be required, together with other document(s) of title relating to such Shares, and to do all such other acts and things as may in the opinion of such attorney-in-fact be necessary or required for the purpose of, or in connection with, the acceptance of the Offer, and to vest title to the Shares (and any and all other Shares or other securities or rights issued or issuable in respect of such Shares) in Purchaser or its nominees as aforesaid.

The undersigned hereby irrevocably appoints Purchaser and any designee of Purchaser and their respective directors, officers, employees and agents (and each and any of the foregoing) as the true and lawful attorneys-in-fact and proxies (in each case, acting individually or with one or much such other attorneys-in-fact or proxies) of the undersigned, each with full power of substitution and re-substitution, to vote in such manner as any such attorney-in-fact and proxy or its substitute shall, in its sole discretion, deem proper, and otherwise act (including pursuant to written consent) with respect to all Shares tendered hereby which have been accepted for payment by Purchaser prior to the time of such vote or action (and any and all other

5

Shares or securities or rights issued or issuable in respect of such Shares), which the undersigned is entitled to vote at any meeting of stockholders (whether annual or special and whether or not an adjourned meeting) of the Company, or by consent in lieu of any such meeting, or otherwise. This proxy and power of attorney is coupled with an interest in the Shares (and any and all other Shares or other securities or rights issued or issuable in respect of such Shares) tendered hereby, is irrevocable, is granted in consideration of, and is effective upon, the acceptance for payment of such Shares (and any and all other Shares or securities or rights issued or issuable in respect of such Shares) by Purchaser in accordance with the terms of the Offer. Such acceptance for payment shall revoke all prior proxies granted by the undersigned at any time with respect to such Shares (and any and all other Shares or securities or rights issued or issuable in respect of such Shares) and no subsequent proxies will be given (and if given will be deemed to be ineffective) with respect thereto by the undersigned.

The undersigned hereby irrevocably undertakes, represents, warrants and agrees (so as to bind the undersigned and its, his or her personal representatives, heirs, successors and assigns) as follows:

(a)

that the undersigned has the full power and authority to tender, sell, assign and transfer the Shares tendered (and any and all other Shares or securities or rights issued or issuable in respect of such Shares), and that Purchaser’s acceptance for payment of Shares tendered pursuant to the Offer will constitute a binding agreement containing the terms and conditions of the Offer, as between Purchaser and the tendering stockholder;

(b)

that the tendering of Shares hereby, and the execution of this Letter of Transmittal, shall constitute: (i) an acceptance of the Offer in respect of the number of Shares identified herein, (ii) an undertaking to execute all further documents and give all further assurances which may be required to enable Purchaser to obtain the full benefit of and to obtain title to the tendered Shares (and any and all other Shares or other securities or rights issued or issuable in respect of such Shares), and (iii) that the undersigned’s acceptance shall be irrevocable, subject to the undersigned not having validly withdrawn such acceptance;

(c)

that the Shares tendered hereby (and any and all other Shares or securities or rights issued or issuable in respect of such Shares) are fully paid and non-assessable, sold free from all liens, equities, charges and encumbrances and together with all rights attaching thereto, including voting rights and the right to all dividends or other distributions having a record date after such Shares have been accepted for purchase in accordance herewith;

(d)

that the tendering of Shares hereby, and the execution of this Letter of Transmittal, constitutes the irrevocable appointment of the Tender Offer Agent and its directors, officers, employees and agents as such holder’s attorney-in-fact and an irrevocable instruction to the attorney-in-fact to complete and execute any and all form(s) of transfer and other document(s) as may be necessary or required, at the discretion of the attorney-in-fact, in order to transfer those Shares (and any and all other Shares or other securities or rights issued or issuable in respect of such Shares) validly tendered and not validly withdrawn, in Purchaser’s name or in the name of such other person(s) as Purchaser may direct, and to deliver such form(s) of transfer and other document(s) as may be required, together with other document(s) of title relating to such Shares (and any and all other Shares or other securities or rights issued or issuable in respect of such Shares), and to do all such other acts and things as may in the opinion of the attorney-in-fact be necessary or required for the purpose of, or in connection with, the acceptance of the Offer, and to vest title to the Shares (and any and all other Shares or other securities or rights issued or issuable in respect of such Shares) in Purchaser or its nominees as aforesaid;

(e)

that the tendering of Shares hereby, and the execution of this Letter of Transmittal, constitutes, subject to the undersigned not having validly withdrawn its tender, an irrevocable authority and request (i) to Purchaser and its directors, officers and agents, to cause the registration of the transfer of the Shares pursuant to the Offer and the delivery of any and all document(s) of title in respect thereof to Purchaser or its nominees and (ii) to Purchaser or Purchaser’s agents, to act upon any instructions with regard to notices and payments that have been recorded in the records of Purchaser regarding such holder’s Shares (and any and all other Shares or other securities or rights issued or issuable in respect of such Shares); and

(f)

that Section 3 of the Offer to Purchase, entitled “PROCEDURES FOR ACCEPTING THE OFFER AND TENDERING SHARES”, is incorporated in and forms part of this Letter of Transmittal.

The undersigned, upon request, will execute and deliver any additional documents deemed by the Tender Offer Agent or Purchaser to be necessary or desirable to complete the sale, assignment and transfer of the Shares tendered hereby (and any such other Shares or securities or rights).

No authority herein conferred or agreed to be conferred in this Letter of Transmittal shall be affected by, and all such authority shall survive, the death or incapacity of the undersigned, and any obligation of the undersigned hereunder shall be binding upon the successors, assigns, heirs, executors, administrators and legal representatives of the undersigned. Except as stated in the Offer to Purchase, this tender is irrevocable.

The undersigned understands that tenders of Shares pursuant to any one of the procedures described in Section 3 of the Offer to Purchase entitled “PROCEDURES FOR ACCEPTING THE OFFER AND TENDERING SHARES” and in the instructions hereto will constitute a binding agreement between the undersigned and Purchaser upon the terms and subject to the conditions of the Offer.

The undersigned hereby affirms its understanding that the Tender Offer Agent will act as agent for all tendering stockholders for the purpose of (i) receiving payment from Purchaser for tendered Shares and (ii) transmitting such payments to the tendering stockholders. Accordingly, upon Purchaser’s deposit with the Tender Offer Agent of the aggregate Cash Consideration required to consummate the Offer, Purchaser’s obligation to pay the Cash Consideration for the Shares will be satisfied, and tendering stockholders must thereafter look solely to the Tender Offer Agent for payment of the Cash Consideration owed to them by reason of the acceptance of Shares pursuant to the Offer.

The undersigned recognizes that, under certain circumstances set forth in the Offer to Purchase, Purchaser may not be required to accept for payment any of the Shares tendered hereby.

The undersigned understands that the CVRs will not be transferable except:

•

The undersigned further understands that the CVRs will not have any voting or dividend rights, or accrue interest, and will not represent any equity or ownership interests in Purchaser, Parent or the Company. The undersigned understands that the CVRs will be registered in the name of the undersigned.

INSTRUCTIONS
Forming Part of the Terms and Conditions of the Offer

1.   Guarantee of Signatures.

No signature guarantee on this Letter of Transmittal is required (i) if this Letter of Transmittal is signed by the registered stockholder(s) (which term, for purposes of this document, shall include any DTC participant whose name appears on a security position listing as the owner of Shares) whose Shares are tendered herewith, unless such stockholder has completed either the box entitled “Special Delivery Instructions” or the box entitled “Special Payment Instructions” on this Letter of Transmittal, or (ii) if the Shares tendered herewith are tendered for the account of a financial institution (including most commercial banks, savings and loan associations and brokerage houses) that is a member in good standing of the Securities Transfer Agents Medallion Program or any other “eligible guarantor institution”, as such term is defined in Rule 17Ad-15 of the Securities Exchange Act of 1934, as amended (each, an “Eligible Institution” and collectively, “Eligible Institutions”). In all other cases, all signatures on this Letter of Transmittal must be guaranteed by an Eligible Institution. Stockholders may also need to have any certificates they deliver endorsed or accompanied by a stock power, and the signatures on these documents may also need to be guaranteed. See Instruction 6.

2.   Delivery of Letter of Transmittal and Certificates.

This Letter of Transmittal is to be completed by stockholders either (i) if certificates representing Shares are to be forwarded herewith to the Tender Offer Agent or (ii) unless an Agent’s Message (as defined below) is utilized, if tenders of Shares are to be made pursuant to the procedures for delivery by book-entry transfer set forth in Section 3 of the Offer to Purchase entitled “PROCEDURES FOR ACCEPTING THE OFFER AND TENDERING SHARES”. Certificates representing all physically tendered Shares, or any Book-Entry Confirmation of Shares, as the case may be, together with a properly completed and duly executed Letter of Transmittal (or facsimile thereof), with any required signature guarantees (or, in connection with a book-entry transfer of uncertificated Shares held through DTC, an Agent’s Message) and any other documents required by this Letter of Transmittal must be received by the Tender Offer Agent at its address or secure upload link set forth herein on or prior to the Expiration Date and Time. If a stockholder’s certificate(s) representing Shares are not immediately available (or the procedure for the book-entry transfer cannot be completed on a timely basis) or time will not permit all required documents to reach the Tender Offer Agent on or prior to the Expiration Date and Time, such stockholder’s Shares may nevertheless be tendered if the procedures for guaranteed delivery set forth in Section 3 of the Offer to Purchase entitled “PROCEDURES FOR ACCEPTING THE OFFER AND TENDERING SHARES” are followed. Pursuant to such procedures, (i) such tender must be made by or through an Eligible Institution, (ii) a properly completed and duly executed Notice of Guaranteed Delivery, substantially in the form provided by Purchaser, must be received by the Tender Offer Agent on or prior to the Expiration Date and Time, and (iii) the certificates representing all tendered Shares, in proper form for transfer, or Book-Entry Confirmation of Shares, as the case may be, in each case, together with a properly completed and duly executed Letter of Transmittal (or facsimile thereof), with any required signature guarantees (or, in connection with a book-entry transfer of uncertificated Shares held through DTC, an Agent’s Message) and any other documents required by this Letter of Transmittal, must be received by the Tender Offer Agent within two Nasdaq trading days after the date of execution of such Notice of Guaranteed Delivery, all as provided in Section 3 of the Offer to Purchase entitled “PROCEDURES FOR ACCEPTING THE OFFER AND TENDERING SHARES”. Shares tendered by Notice of Guaranteed Delivery will be excluded from the calculation of the Minimum Condition (as defined in the Offer to Purchase) unless such Shares and other documents are received by the Tender Offer Agent by the Expiration Date and Time.

The term “Agent’s Message” means a message transmitted through electronic means by DTC to, and received by, the Tender Offer Agent and forming a part of a Book-Entry Confirmation, which states that DTC has received an express acknowledgment from the DTC participant tendering Shares that such participant has received, and agrees to be bound by, this Letter of Transmittal. DELIVERY OF DOCUMENTS TO DTC IN ACCORDANCE WITH DTC’S PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE TENDER OFFER AGENT.

11

THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, THE CERTIFICATE(S) REPRESENTING SHARES AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH DTC, IS AT THE OPTION AND SOLE RISK OF THE TENDERING STOCKHOLDER. THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE TENDER OFFER AGENT. IF SUCH 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.

3.   No Alternative, Conditional or Contingent Tenders.

No alternative, conditional or contingent tenders will be accepted, and no fractional Shares will be purchased by Purchaser in the Offer. All tendering stockholders, by execution of this Letter of Transmittal (or facsimile hereof), waive any right to receive any notice of the acceptance of their Shares for payment.

4.   Inadequate Space.

If the space provided in the Letter of Transmittal is inadequate, the certificate numbers and/or the number of Shares should be listed on a separate signed schedule attached hereto.

5.   Partial Tenders (Not Applicable to Stockholders Who Tender Shares by Book-Entry Transfer).

If fewer than all Shares represented by any certificate submitted are to be tendered, fill in the number of Shares that are to be tendered in the box entitled “Number of Shares Tendered”. In such case, new certificate(s) representing the remainder of Shares that were represented by the old certificate(s) will be sent to the registered stockholder(s) as soon as practicable after the Expiration Date and Time. All Shares represented by certificate(s) delivered to the Tender Offer Agent will be deemed to have been tendered unless otherwise indicated.

6.   Signatures on Letter of Transmittal, Stock Powers and Endorsements.

If this Letter of Transmittal is signed by the registered stockholder(s) of Shares tendered hereby, the signature(s) must correspond exactly with the name(s) as written on the face(s) of the certificate(s) without alteration, enlargement or any change whatsoever. If any of Shares tendered hereby are owned of record by two or more joint owners, all such owners must sign this Letter of Transmittal. If any tendered Shares 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 is signed by the registered stockholder(s) of Shares listed and tendered hereby, no endorsements of certificates or separate stock powers are required, unless payment is to be issued to a person other than the registered stockholder(s) (in which case, signatures on such certificates or stock powers must be guaranteed by an Eligible Institution).

If this Letter of Transmittal or any certificates or stock powers are signed by a trustee, executor, administrator, guardian, attorney-in-fact, officer of a corporation or other person acting in a fiduciary or representative capacity, such person should so indicate when signing, and proper evidence satisfactory to Purchaser and Tender Offer Agent of such person’s authority so to act must be submitted.

If this Letter of Transmittal is signed by a person other than the registered stockholder(s) of Shares tendered hereby, the certificates must be endorsed or accompanied by appropriate stock powers, in either case, signed exactly as the name(s) of the registered stockholder(s) appear on the certificates. Signatures on such certificates or stock powers must be guaranteed by an Eligible Institution, unless the signature is that of an Eligible Institution.

7.   Special Payment and Delivery Instructions.

If a check for the aggregate Cash Consideration for all Shares accepted for payment is to be issued to a person other than the signer(s) of this Letter of Transmittal or to an address other than that shown in the box titled “Description of Shares Tendered” above, the appropriate boxes on this Letter of Transmittal should be completed. See the boxes above entitled “Special Payment Instructions” or “Special Delivery

12

Instructions”, as applicable. Stockholders delivering Shares tendered hereby or by Agent’s Message by book-entry transfer may request that Shares not purchased be credited to an account maintained at DTC as such stockholder may designate in the box titled “Special Payment Instructions” herein. If no such instructions are given, all such Shares not purchased will be returned by crediting the same account at DTC as the account from which such Shares were delivered.

8.   Lost, Destroyed, Mutilated or Stolen Certificates.

If any certificate(s) representing Shares has been lost, destroyed, mutilated or stolen, the stockholder should promptly contact the Information Agent. The stockholder will then be instructed as to the steps that must be taken in order to replace the certificate(s). This Letter of Transmittal and related documents cannot be processed until the procedures for replacing lost, destroyed, mutilated or stolen certificates have been followed.

9.   Conditions for Completion of the Offer; Waiver.

Purchaser is not required to accept for payment nor, subject to any applicable rules and regulations of the U.S. Securities and Exchange Commission, required to pay for any tendered Shares unless the conditions set forth in Section 15 of the Offer to Purchase entitled “CONDITIONS OF THE OFFER” ​(collectively, the “Offer Conditions”) are satisfied or waived in accordance therewith. Purchaser and Parent expressly reserve the right, in their sole discretion, to waive any Offer Condition (other than the Minimum Condition) subject to the terms and conditions of the Merger Agreement (as defined in the Offer to Purchase) and the applicable rules and regulations of the U.S. Securities and Exchange Commission.

Purchaser is not obligated and does not intend to extend the Offer beyond the Expiration Date and Time. However, Purchaser is required or permitted to extend the Offer under certain circumstances, as further described in Section 1 of the Offer to Purchase entitled “TERMS OF THE OFFER”.

10.   Determination of Validity.

All questions as to the form of documents and the validity, eligibility (including time of receipt) and acceptance for payment of any tendered Shares will be determined by Purchaser, in its sole discretion. Purchaser reserves the absolute right to reject any or all tenders of any Shares (and any and all other Shares or other securities or rights issued or issuable in respect of such Shares) that it determines are not in appropriate form or the acceptance for payment of or payment for which may, in its opinion, be unlawful. Purchaser also reserves the absolute right to waive any defect or irregularity in any tender with respect to any particular Shares (and any and all other Shares or other securities or rights issued or issuable in respect of such Shares) or any particular stockholder. No tender of Shares (and any and all other Shares or other securities or rights issued or issuable in respect of such Shares) will be deemed to have been validly made until all defects or irregularities relating thereto have been expressly waived or cured to the satisfaction of Purchaser. THE UNDERSIGNED UNDERSTANDS THAT, SUBJECT TO THE TERMS OF THE MERGER AGREEMENT, PURCHASER’S INTERPRETATION OF THE TERMS AND CONDITIONS OF THE OFFER (INCLUDING THIS LETTER OF TRANSMITTAL AND THE INSTRUCTIONS HERETO) WILL BE FINAL AND BINDING TO THE FULLEST EXTENT PERMITTED BY LAW. ALL QUESTIONS AS TO THE FORM OF DOCUMENTS AND THE VALIDITY, FORM, ELIGIBILITY (INCLUDING TIME OF RECEIPT) AND ACCEPTANCE FOR PAYMENT OF ANY SHARES WILL BE DETERMINED BY PURCHASER IN ITS DISCRETION, WHICH DETERMINATION WILL BE FINAL AND BINDING TO THE FULLEST EXTENT PERMITTED BY LAW. None of Purchaser, Parent, the Tender Offer Agent, the Information Agent 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.

11.   Requests for Assistance or Additional Copies.

Requests for assistance may be directed to the Information Agent at the address set forth below. Additional copies of the Offer to Purchase, this Letter of Transmittal, the Notice of Guaranteed Delivery and the IRS Form W-9 may be obtained from the Information Agent at its address set forth below or from your broker, dealer, commercial bank, trust company or other nominee.

12.   Withdrawals.

Tenders of Shares made pursuant to the Offer are irrevocable except as otherwise provided here and as further described in Section 4 of the Offer to Purchase entitled “WITHDRAWAL RIGHTS”. A stockholder may withdraw Shares that it has previously tendered pursuant to the Offer pursuant to the procedures set forth below at any time prior to the Expiration Date and Time. Thereafter, tenders of Shares are irrevocable, except that if Purchaser has not accepted the Shares for payment by January 12, 2024, the 60th day after commencement of the Offer, you may withdraw them at any time after January 12, 2024, until Purchaser accepts your Shares for payment.

Purchaser expects to accept for payment and thereafter pay for all Shares validly tendered into the Offer and not validly withdrawn as soon as practicable following the Expiration Date and Time.

Withdrawals of tenders of Shares may not be rescinded, and Shares properly withdrawn will thereafter be deemed not validly tendered for purposes of the Offer. However, withdrawn Shares may be retendered at any time before the Expiration Date and Time.

All questions as to the form and validity (including time of receipt) of notices of withdrawal will be determined by Purchaser, in its sole discretion. None of Purchaser, Parent, the Tender Offer Agent, the Information Agent 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.

13.   Stock Transfer Taxes

Except as otherwise provided in this Instruction 13, Purchaser will pay any stock transfer taxes with respect to the sale and transfer of any Shares to it or to its order pursuant to the Offer. If, however, consideration is to be paid to, or Shares not tendered or not accepted for payment are to be returned in the name of, any person other than the registered stockholder(s), if tendered certificate(s) for Share(s) are registered in the name of any person(s) other than the person(s) signing this Letter of Transmittal, or if a transfer tax is imposed for any reason other than the sale or transfer of Shares to Purchaser pursuant to the Offer, Purchaser will not be responsible for any stock transfer or similar taxes (whether imposed on the registered holder(s) or such other person(s) or otherwise) payable on account of the transfer to such other person(s) and no consideration shall be paid in respect of such Share(s) unless evidence satisfactory to Purchaser of the payment of such taxes, or the inapplicability of such taxes, is submitted.

14.   Backup Withholding; IRS Forms

Under U.S. federal income tax laws, unless certain certification requirements are met, the Tender Offer Agent generally will be required to withhold at the applicable backup withholding rate (currently, 24%) from any payments made to certain stockholders pursuant to the Offer. In such cases, in order to avoid such backup withholding, each tendering stockholder, and, if applicable, each other payee, must provide the Tender Offer Agent with such stockholder’s or payee’s correct taxpayer identification number (“TIN”) and certify that such stockholder or payee is not subject to such backup withholding by properly completing the enclosed IRS Form W-9 as described in the enclosed instructions to IRS Form W-9, or if such stockholder or payee is not a U.S. person for U.S. federal income tax purposes, by submitting an appropriate and properly completed IRS Form W-8, available from the Tender Offer Agent or the IRS website at http://www.irs.gov, in each case, in accordance with the appropriate instructions. Stockholders that are not U.S. persons or that have questions regarding their status for U.S. federal income tax purposes should consult their tax advisors to determine which IRS Form is appropriate.

For U.S. federal tax purposes, a holder is considered a U.S. person if the holder is: (1) a citizen or individual resident of the United States, (2) a partnership, corporation, or entity treated as a partnership or corporation, organized in or under the laws of the United States or any state thereof or the District of Columbia, (3) a trust that (i) is subject to (a) the primary supervision of a court within the United States and (b) the authority of one or more U.S. persons to control all substantial decisions of the trust or (ii) has a valid election in effect under applicable Treasury Regulations to be treated as a U.S. person or (4) an estate that is subject to U.S. federal income tax on its income regardless of its source.

14

Certain stockholders or payees (including, among others, all corporations and certain foreign persons) are not subject to backup withholding. Such stockholders should nevertheless properly complete the enclosed IRS Form W-9 to avoid possible erroneous backup withholding or submit to the Tender Offer Agent an appropriate and properly completed IRS Form W-8 signed under penalties of perjury, attesting to the exempt status of such stockholders or payees (whichever is applicable). IRS Forms W-8 are available from the Tender Offer Agent or the IRS website at http://www.irs.gov. Please review the instructions on the enclosed IRS Form W-9 or appropriate IRS Form W-8 for additional guidance on which stockholders are exempt from backup withholding.

Failure to properly complete the enclosed IRS Form W-9 or to submit an appropriate and properly completed IRS Form W-8 will not, by itself, cause Shares to be deemed invalidly tendered, but will require the Tender Offer Agent to withhold from any payments made pursuant to the Offer.

Backup withholding is not an additional U.S. federal income tax. Rather, the U.S. federal income tax liability of a person subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund may be obtained provided that the required information is timely furnished to the IRS. Failure to properly complete and return the enclosed IRS Form W-9 or an applicable IRS Form W-8 will result in backup withholding from any payments made to you pursuant to the Offer. IRS Forms W-9 and W-8 are available from the Tender Offer Agent or the IRS website at http://www.irs.gov. Stockholders should consult their tax advisors to determine which such IRS Form is appropriate.

For a discussion of certain U.S. federal income tax consequences of the Offer, see Section 5 of the Offer to Purchase entitled “MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES”.

15.   Tender Constitutes an Agreement.

The tender of Shares pursuant to any one of the procedures described above will constitute your acceptance of the Offer, as well as your representation and warranty with respect to each of the matters set forth above (including, without limitation, your representation and warranty that you have the full power and authority to tender, sell, assign and transfer the Shares (and any and all other Shares or other securities or rights issued or issuable in respect of such Shares) tendered). Purchaser’s acceptance for payment of Shares tendered by you pursuant to the Offer will constitute a binding agreement between you and Purchaser with respect to such Shares (and any and all other Shares or other securities or rights issued or issuable in respect of such Shares), upon the terms and subject to the conditions of the Offer.
