Dear Sirs and Mesdames:

        Herbalife Ltd. (f/k/a WH Holdings (Cayman Islands) Ltd.), a Cayman Islands exempted limited liability company (the "Company"), proposes to issue and sell to the several Underwriters named in Schedule II hereto (the "Underwriters"), and certain shareholders of the Company (the "Selling Shareholders") named in Schedule I hereto severally propose to sell the several Underwriters, an aggregate of 14,500,000 shares of the common shares, par value $0.002 per share of the Company (the "Firm Shares"), of which 1,000,000 shares are to be sold by the Selling Shareholders, each Selling Shareholder selling the amount set forth opposite such Selling Shareholder's name in Schedule I hereto. The Company also proposes to issue and sell to the several Underwriters not more than an additional 2,175,000 shares of its common shares, par value $0.002 per share (the "Additional Shares") if and to the extent that you, as Representatives of the offering, shall have determined to exercise, on behalf of the Underwriters, the right to purchase such common shares granted to the Underwriters in Section 3 hereof. The Firm Shares and the Additional Shares are hereinafter collectively referred to as the "Shares." The common shares, par value $0.002 per share, of the Company to be outstanding after giving effect to the sales contemplated hereby are hereinafter referred to as the "Common Shares." The Company and the Selling Shareholders are hereinafter sometimes collectively referred to as the "Sellers."

        The net proceeds of the offering of the Shares to be sold by the Company, together with available cash of the Company and borrowings under the New Credit Facility (as defined below), will be used to consummate a series of recapitalization transactions, as follows: (i) the purchase of up to $160.0 million aggregate principal amount of Herbalife International, Inc.'s ("Herbalife International") 113/4% senior subordinated notes due 2010 (such purchase, the "Tender Offer"), (ii) the redemption of 40% of the Company's outstanding 91/2% notes due 2011 (the "Redemption"), (iii) the replacement of Herbalife International's existing $205.0 million senior credit facility with a new $225.0 million senior credit facility (the "New Credit Facility") (such replacement and the entry into the New Credit Facility, the "Replacement of Existing Credit Facility"), (iv) the payment of a dividend in the amount of $109.3 million subject to upward adjustment in the event that the Underwriters exercise their overallotment option (up to $143.0 million if the Underwriters exercise their overallotment option in full) to the Company's shareholders of record prior to the date of issuance of the Shares (the "Dividend") and (v) the amendment of the Company's memorandum and articles of association to (x) effect a 1-for-2 reverse stock split of its common shares, (y) increase its authorized common shares to 500 million shares, and (z) increase its authorized preference shares to 7.5 million shares (the "Stock Split", and together with the Tender Offer, the Redemption, the Replacement of Existing Credit Facility and the Dividend, the "Recapitalization Transactions").

        The Company has filed with the Securities and Exchange Commission (the "Commission") a registration statement on Form S-1 (No. 333-119485), including the related preliminary prospectus or prospectuses, covering the registration of the Securities under the Securities Act of 1933, as amended

(the "Securities Act"). Promptly after execution and delivery of this Agreement, the Company will prepare and file a prospectus in accordance with the provisions of Rule 430A ("Rule 430A") of the rules and regulations of the Commission under the Securities Act (the "Securities Act Regulations") and paragraph (b) of Rule 424 ("Rule 424(b)") of the Securities Act Regulations. The information included in such prospectus that was omitted from such registration statement at the time it became effective but that is deemed to be part of such registration statement at the time it became effective pursuant to paragraph (b) of Rule 430A is referred to as "Rule 430A Information." Each prospectus used before such registration statement became effective, and any prospectus that omitted the Rule 430A Information, that was used after such effectiveness and prior to the execution and delivery of this Agreement, is herein called a "preliminary prospectus." Such registration statement, including the exhibits and any schedules thereto, at the time it became effective, and including the Rule 430A Information, is herein called the "Registration Statement." Any registration statement filed pursuant to Rule 462(b) of the Securities Act Regulations is herein referred to as the "Rule 462(b) Registration Statement," and after such filing the term "Registration Statement" shall include the Rule 462(b) Registration Statement. The final prospectus in the form first furnished to the Underwriters for use in connection with the offering of the Securities is herein called the "Prospectus." For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus, the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system ("EDGAR").

        Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch") has agreed to reserve a portion of the Shares to be purchased by it under this Agreement for sale to the Company's directors, officers, employees and business associates and other parties related to the Company (collectively, "Participants"), as set forth in the Prospectus under the heading "Underwriters" (the "Directed Share Program"). The Shares to be sold by Merrill Lynch and certain of its affiliates pursuant to the Directed Share Program are referred to hereinafter as the "Directed Shares." Any Directed Shares not confirmed for purchase by any Participants by the end of the business day on which this Agreement is executed will be offered to the public by the Underwriters as set forth in the Prospectus.

        Any certificate signed by or on behalf of a Selling Shareholder as such and delivered to the Representatives or to counsel for the Underwriters pursuant to the terms of this Agreement shall be deemed a representation and warranty by such Selling Shareholder to the Underwriters as to the matters covered thereby.

        3.    Agreements to Sell and Purchase.    Each Seller, severally and not jointly, hereby agrees to sell to the several Underwriters, and each Underwriter, upon the basis of the representations and warranties herein contained, but subject to the conditions hereinafter stated, agrees, severally and not jointly, to purchase from such Seller at $            per share (the "Purchase Price") the number of Firm Shares (subject to such adjustments to eliminate fractional shares as you may determine) that bears the same proportion to the number of Firm Shares to be sold by such Seller as the respective number of Firm Shares set forth in Schedule II hereto opposite the name of such Underwriter bears to the total number of Firm Shares.

11



        On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, the Company agrees to sell to the Underwriters the Additional Shares, and the Underwriters shall have the right to purchase, severally and not jointly, up to 2,175,000 Additional Shares at the Purchase Price. You may exercise this right on behalf of the Underwriters in whole or from time to time in part by giving written notice of each election to exercise the option not later than 30 days after the date of this Agreement. Any such exercise notice shall specify the number of Additional Shares to be purchased by the Underwriters and the date on which such shares are to be purchased. Each purchase date must be at least one business day after the written notice is given and may not be earlier than the Closing Date (as defined below) nor later than ten business days after the date of such notice. Additional Shares may be purchased as provided in Section 5 hereof solely for the purpose of covering over-allotments made in connection with the offering of the Firm Shares. On each Option Closing Date (as defined below), each Underwriter agrees, severally and not jointly, to purchase the number of Additional Shares (subject to such adjustments to eliminate fractional shares as you may determine) that bears the same proportion to the total number of Additional Shares to be purchased on such Option Closing Date as the number of Firm Shares set forth in Schedule II hereto opposite the name of such Underwriter bears to the total number of Firm Shares.

12


        Each of the Sellers (other than the Sponsors (as defined below) who have delivered "lock-up" agreements substantially in the form of Exhibit A hereto), severally and not jointly, hereby agrees that, without the prior written consent of Merrill Lynch, Pierce, Fenner & Smith Incorporated and Morgan Stanley & Co. Incorporated, on behalf of the Underwriters, it will not, during the period ending 180 days after the date of the Prospectus, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Common Shares or any securities convertible into or exercisable or exchangeable for Common Shares or (ii) file any registration statement with the Commission relating to the offering of any Common Shares or any securities convertible into or exercisable or exchangeable for Common Shares or (iii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Shares, whether any such transaction described in clause (i), (ii) or (iii) above is to be settled by delivery of Common Shares or such other securities, in cash or otherwise.

        The restrictions contained in the preceding paragraph shall not apply to (A) the Shares to be sold hereunder, (B) the issuance by the Company of Common Shares upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof of which the Underwriters have been advised in writing or (C) transactions by any person other than the Company relating to Common Shares or other securities acquired in open market transactions after the completion of the offering of the Shares. In addition, each Selling Shareholder, (other than the Sponsors who have delivered "lock-up" agreements substantially in the form of Exhibit A hereto), severally and not jointly, agrees that, without the prior written consent of Merrill Lynch, Pierce, Fenner & Smith Incorporated and Morgan Stanley & Co., Incorporated, on behalf of the Underwriters, it will not, during the period ending 180 days after the date of the Prospectus, make any demand for, or exercise any right with respect to, the registration of any Common Shares or any security convertible into an exercisable or exchangeable for Common Shares. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company's transfer agent and registrar against the transfer of the undersigned's Common Shares except in compliance with the foregoing restrictions.

        Notwithstanding the foregoing, if (1) during the last 17 days of the 180-day restricted period the Company issues an earnings release or material news or a material event relating to the Company occurs; or (2) prior to the expiration of the 180-day restricted period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the 180-day period, the restrictions imposed by this letter shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

        4.    Terms of Public Offering.    The Sellers are advised by you that the Underwriters propose to make a public offering of their respective portions of the Shares as soon after the Registration Statement and this Agreement have become effective as in your judgment is advisable. The Sellers are further advised by you that the Shares are to be offered to the public initially at $    a share (the "Public Offering Price") and to certain dealers selected by you at a price that represents a concession not in excess of $            a share under the Public Offering Price, and that any Underwriter may allow, and such dealers may reallow, a concession, not in excess of $    a share, to any Underwriter or to certain other dealers.

        5.    Payment and Delivery.    Payment for the Firm Shares to be sold by each Seller shall be made to such Seller in Federal or other funds immediately available in New York City against delivery of such Firm Shares for the respective accounts of the several Underwriters at 10:00 a.m., New York City time, on                         , 2004, or at such other time on the same or such other date, not later than                        , 2004, as shall be designated in writing by you.

The time and date of any such payment are hereinafter referred to as an "Option Closing Date." The closing of the offering and sale of Additional Shares will be held at the offices of Skadden, Arps, Slate, Meagher & Flom LLP, 300 South Grand Avenue, Suite 3400, Los Angeles, California 90071.

        The Firm Shares and Additional Shares shall be registered in such names and in such denominations as you shall request in writing not later than one full business day prior to the Closing Date or the applicable Option Closing Date, as the case may be. The Firm Shares and Additional Shares shall be delivered to you on the Closing Date or an Option Closing Date, as the case may be, for the respective accounts of the several Underwriters, with any transfer taxes payable in connection with the transfer of the Shares to the Underwriters duly paid, against payment of the Purchase Price therefor.

If any Selling Shareholder is required to deduct or withhold any Governmental Taxes, or if any Governmental Taxes are required to be paid any Selling Shareholder pursuant to this Agreement (other than any Tax imposed on a net income basis), the Selling Shareholder shall pay to such recipient such additional amounts as necessary so that the net amount received by such direct or indirect recipient after such deduction, withholding or payment (taking into account any deductions, withholdings or payment of Governmental Taxes that may be applicable to such additional amounts) will equal the amount otherwise due to such recipient hereunder. The Selling Shareholder shall pay promptly the full amount of Governmental Taxes withheld or deducted to the relevant tax authority in accordance with applicable law.

        The provisions of this Section 9 shall not supersede or otherwise affect, or be affected by, any agreement that the Sellers may otherwise have for the allocation of such expenses among themselves.

        10.    Indemnity.    (a) The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, as such term is defined in Rule 501(b) under the Securities Act (each, an "Affiliate"), its selling agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act as follows:

18


provided, however, that this indemnity agreement shall not apply to any Loss to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430A Information, or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto); provided further, however, this indemnity agreement shall not apply, with respect to any particular Underwriter, to any Loss to the extent arising out of any untrue statement or omission or alleged untrue statement or omission contained in any preliminary prospectus to the extent that the Company complied with its prospectus delivery requirements contained herein and the particular Underwriter was legally required to and failed to send or give a copy of the Prospectus, as then amended or supplemented, to the person alleging such defect and the untrue statement or alleged untrue statement of a material fact or omission or alleged omission to state a material fact in such preliminary prospectus was corrected in such Prospectus.

19


provided, however, that this indemnity agreement shall not apply to any Loss to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representative expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430A Information, or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto); provided further, however, this indemnity agreement shall not apply, with respect to any particular Underwriter, to any Loss to the extent arising out of any untrue statement or omission or alleged untrue statement or omission contained in any preliminary prospectus to the extent that the Company complied with its prospectus delivery requirements contained herein and the particular Underwriter was legally required to and failed to send or give a copy of the Prospectus, as then amended or supplemented, to the person alleging such defect and the untrue statement or alleged untrue statement of a material fact or omission or alleged omission to state a material fact in such preliminary prospectus was corrected in such Prospectus; provided, further, that a Selling Shareholder shall be liable for Losses pursuant to this indemnity only to the extent that such Loss arises our of, or is based upon, any untrue statement or alleged untrue statement or any omission or alleged omission that was made in conformity with written information concerning such Selling Shareholder furnished to the Company by or on behalf of that Selling Shareholder specifically for inclusion thereon; provided, further, that no Selling Shareholder shall be responsible pursuant to this indemnity for Losses for an amount in excess of the net amount of proceeds such Selling Shareholder received from the sale of the Shares hereunder.

20


21


        11.    Contribution.    If the indemnification provided for in Section 10 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any Losses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such Losses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Shareholders on the one hand and the Underwriters on the other hand from the offering of the Shares pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Selling Shareholders on the one hand and of the Underwriters on the other hand in connection with the statements or omissions, or in connection with any violation of the nature referred to in Section 10(f) hereof, which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

        The relative benefits received by the Company and the Selling Shareholders on the one hand and the Underwriters on the other hand in connection with the offering of the Shares pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Shares pursuant to this Agreement (before deducting expenses) received by the Company and the Selling Shareholders and the total underwriting discount received by the Underwriters, in each case as set forth on the cover of the Prospectus bear to the aggregate initial public offering price of the Securities as set forth on the cover of the Prospectus.

        The relative fault of the Company and the Selling Shareholders on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Selling Shareholders or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or any violation of the nature referred to in Section 10(f) hereof.

        The Company, the Selling Shareholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 11 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 11. The aggregate amount of Losses incurred by an indemnified party and referred to above in this Section 10 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

        Notwithstanding the provisions of this Section 11, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

        Notwithstanding the provisions of this Section 11, no Selling Shareholder shall be required to contribute any amount in excess of the amount by which the net amount of the proceeds such Selling Shareholder received from the sale of the Shares pursuant to this Agreement exceeds the amount of any damages which such Selling Shareholder has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

        No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

22



        For purposes of this Section 11, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each Underwriter's Affiliates and selling agents shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company or any Selling Shareholder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company or such Selling Shareholder, as the case may be. The Underwriters' respective obligations to contribute pursuant to this Section 11 are several in proportion to the number of Firm Shares set forth opposite their respective names in Schedule II hereto and not joint.

        The provisions of this Section 11 shall not affect any agreement among the Company and the Selling Shareholders with respect to contribution.

        12.    Termination.    The Underwriters may terminate this Agreement by notice given to the Company and the Selling Shareholders, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the American Stock Exchange, the Nasdaq National Market, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade or other relevant exchanges, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State or relevant foreign country authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in your judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in your judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Prospectus.

        13.    Effectiveness; Defaulting Underwriters; Defaulting Sellers.    (a) This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

23


        14.    Notice.    All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed, delivered or telefaxed. Notices to the Underwriters shall be directed to the Representatives at 4 World Financial Center, New York, New York 10080, attention: Global Origination Counsel Group, notices to the Company shall be directed to it at 1800 Century Park East, Los Angeles, California 90067, attention: Brett R. Chapman and notices to each Selling Shareholder shall be directed to such Selling Shareholder at its address set forth on Schedule I.

        15.    Counterparts.    This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

        16.    Jurisdiction.    The Company and each Selling Shareholder agrees that any suit, action or proceeding against any of them brought by any Underwriter, its directors, officers, employees, Affiliates, selling agents or by any person who controls any Underwriter, arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in any New York Court, and waives any objection which it may now or hereafter have to the laying of venue of any such proceeding, and irrevocably submits to the nonexclusive jurisdiction of such courts in any suit, action or proceeding. The Company hereby appoints Corporation Service Company as its authorized agent (the "Authorized Agent") upon whom process may be served in any suit, action or proceeding arising our of or based

24



upon this Agreement or the transactions contemplated herein that may be instituted in any New York Court, by any Underwriter, the directors, officers, employees, Affiliates, selling agents or by any person who controls any Underwriter, and expressly accepts the nonexclusive jurisdiction of any such court in respect of any such suit, action or proceeding. The Company hereby represents and warrants that the Authorized Agent has accepted such appointment and has agreed to act as said agent for service of process, and the Company agrees to take any and all action, including the filing of any and all documents that may be necessary to continue such appointment in full force and effect as aforesaid. Service of process upon the Authorized Agent shall be deemed, in every respect, effective service of process upon the Company. Notwithstanding the foregoing, any action arising out of or based upon this Agreement may be instituted by any Underwriter, its directors, officers, employees, Affiliates, selling agents or by any person who controls any Underwriter, in any court of competent jurisdiction in the Cayman Islands. The parties hereto each hereby waive any right to trial by jury in any action, proceeding or counterclaim arising out of or relating to this Agreement.

Dear Sirs and Mesdames:

        The undersigned understands that Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch") and Morgan Stanley & Co. Incorporated ("Morgan Stanley" and together with Merrill Lynch, the "Representatives") propose to enter into a Purchase Agreement (the "Purchase Agreement") with Herbalife Ltd. (f/k/a WH Holdings (Cayman Islands) Ltd.), a Cayman Islands exempted limited liability company (the "Company") and the selling stockholders party thereto, providing for the public offering (the"Public Offering") by the several Underwriters, including Merrill Lynch and Morgan Stanley (the "Underwriters"), of the Common Shares (par value $0.002 per share) of the Company (the "Common Shares").

        To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of the Representatives on behalf of the Underwriters, it will not, during the period commencing on the date hereof and ending 180 days after the date of the final prospectus relating to the Public Offering (the "Prospectus"), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Common Shares or any securities convertible into or exercisable or exchangeable for Common Shares or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of Common Shares, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Shares or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (a) transactions relating to Common Shares or other securities acquired in open market transactions after the completion of the Public Offering, provided that no filing by any party under the Securities Exchange Act of 1934 (the "Exchange Act") shall be required or shall be voluntarily made in connection with subsequent sales of Common Shares or other securities acquired in such open market transactions or (b) transfers of Common Shares or any security convertible into Common Shares as a bona fide gift or gifts; provided that in the case of any transfer or distribution pursuant to clause (b), (i) each donee or distributee shall sign and deliver a lock-up letter substantially in the form of this letter and (ii) the undersigned shall not be required to, and shall not voluntarily, file a report under Section 16(a) of the Exchange Act, reporting a reduction in beneficial ownership of Common Shares during the restricted period referred to in the foregoing sentence. In addition, the undersigned agrees that, without the prior written consent of the Representatives on behalf of the Underwriters, it will not, during the period commencing on the date hereof and ending 180 days after the date of the Prospectus, make any demand for or exercise any right with respect to, the registration of any Common Shares or any security convertible into or exercisable or exchangeable

for Common Shares. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company's transfer agent and registrar against the transfer of the undersigned's Common Shares except in compliance with the foregoing restrictions.

        If:

the restrictions imposed by this letter shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

        The undersigned hereby acknowledges and agrees that written notice of any extension of the 180-day restricted period pursuant to the previous paragraph will be delivered by the Representatives to the Company (in accordance with the Purchase Agreement) and that any such notice properly delivered will be deemed to have given to, and received by, the undersigned. The undersigned further agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this Lock-Up Agreement during the period from the date of this Lock-Up Agreement to and including the 34th day following the expiration of the initial 180-day restricted period, it will give notice thereof to the Company and will not consummate such transaction or take any such action unless it has received written confirmation from the Company that the 180-day restricted period (as may have been extended pursuant to the previous paragraph) has expired.

        The undersigned understands that the Company and the Underwriters are relying upon this agreement in proceeding toward consummation of the Public Offering. The undersigned further understands that this agreement is irrevocable and shall be binding upon the undersigned's heirs, legal representatives, successors and assigns.

        Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to an Purchase Agreement, the terms of which are subject to negotiation between the Company and the Underwriters.

    Very truly yours,
