ADJUSTMENTS. The number of Shares for which this Warrant is exercisable, and the price at which such Shares may be purchased upon exercise of this Warrant, shall be subject to adjustment from time to time as set forth in this Section 4. The Company shall give each Holder notice of any event described below, which requires an adjustment pursuant to this Section 4 at the time of such event.

     4.1 Distributions, Subdivisions and Combinations. If, at any time, the Company, or in the case of (d) below, the Company or the holders of the equity securities of the Company:

     (a) takes a record of holders of its Shares for the purpose of entitling them to receive a distribution payable in, or other distribution of, Additional Shares,

     (b) subdivides its outstanding Shares into a larger number of Shares,

     (c) combines its outstanding Shares into a smaller number of Shares, or

     (d) form a new holding company to be the parent of the Company and to own one hundred percent (100%) of the Shares (“Holdco”),

then (i) the number (and kind, in the case of (d) above) of Warrant Shares represented by this Warrant immediately after the occurrence of any such event shall be adjusted to equal the number (and kind, in the case of (d) above) of Shares that a record holder of the same number of Shares for which this Warrant is exercisable immediately prior to the occurrence of such event would own or be entitled to receive after the happening of such event, and (ii) the Exercise Price shall be adjusted to equal (A) the then existing Exercise Price multiplied by the number of Shares for which this Warrant is exercisable immediately prior to the adjustment divided by (B) the number of Shares for which this Warrant is exercisable immediately after such adjustment. In the case of (d) above, by way of illustration and not limitation, if Holdco is formed to own one hundred percent (100%) of the Shares and other equity interests of the Company and, immediately prior to such formation, ten percent (10%) of the Shares are subject to this Warrant, Holder shall receive a warrant to purchase ten percent (10%) of the common equity interests of Holdco upon the exchange and cancellation of this Warrant.

     4.2 Certain Other Distributions. If, at any time, the Company takes a record of holders of its Shares for the purpose of entitling them to receive any distribution of:

     (a) any evidences of its indebtedness, any other securities of any nature whatsoever (other than Additional Shares) or any other property, dividends or other cash distributions, or

     (b) any options to subscribe for or purchase any evidences of its indebtedness, or for any other securities of any nature whatsoever (other than Additional Shares) or for any other property,

then (i) the number of Shares for which this Warrant is exercisable shall be adjusted to equal the product of the number of Shares for which this Warrant is exercisable immediately prior to such adjustment by a fraction (A) the numerator of which shall be the Current Market Price per Share at the date of taking such record and (B) the denominator of which shall be such Current Market Price per Share at the date of taking such record, plus the amount of consideration, if any, paid by the holder of one (1) Share for such evidence of indebtedness, other securities or property, or Options so distributable and minus the amount allocable to one (1) Share of the fair value (as determined in good faith by the Board and supported by an opinion from an Independent Financial Expert) of any and all such evidences of indebtedness, Shares, other securities or property or warrants or other subscription or purchase rights so distributable, and (ii) the Exercise Price shall be adjusted to equal (A) the Exercise Price multiplied by the number of Shares for which this Warrant is exercisable immediately prior to the adjustment divided by (B) the number of Shares for which this Warrant is exercisable immediately after such adjustment.

     4.3 Issuance of Additional Shares. If, at any time, Company issues or sells any Additional Shares other than Permitted Shares, in exchange for consideration in an amount per Additional Share less than the Exercise Price at the time the Additional Shares are issued, then

     (a) the Exercise Price for which this Warrant is exercisable shall be reduced to a price equal to the price obtained by multiplying (i) the Exercise Price in effect immediately prior to the issuance of such Additional Shares by (ii) a fraction of which (x) the numerator equals the sum of (i) the number of Fully Diluted Outstanding Shares immediately prior to such issue or sale and (ii) the number of additional Shares that the aggregate consideration received by Company upon such issue or sale would purchase at the Exercise Price in effect immediately prior to such issuance and (y) the denominator equals the total number of Fully Diluted Outstanding Shares outstanding immediately after such issue or sale; and

     (b) the number of Shares for which this Warrant is exercisable shall be adjusted to equal the product obtained by multiplying the Exercise Price in effect immediately prior to such issue or sale by the number of Shares for which this Warrant is exercisable immediately prior to such issue or sale and dividing the product thereof by the Exercise Price resulting from the adjustment made pursuant to clause (i) above.

     4.4 Issuance of Warrants or Other Rights. If, at any time, the Company shall take a record of holders of its Shares for the purpose of entitling them to receive a distribution of, or shall in any manner (whether directly or by assumption in a merger where the Company is the

surviving entity) issue or sell, any warrants or other rights to subscribe for or purchase any Additional Shares other than Permitted Shares or any Convertible Securities other than Permitted Shares, whether or not the rights to exchange or convert thereunder are immediately exercisable, and the price per Share for which Shares are issuable upon the exercise of such warrants or other rights or upon conversion or exchange of such Convertible Securities shall be less than the Exercise Price in effect immediately prior to the time of such issue or sale, then the number of Shares for which this Warrant is exercisable and the Exercise Price shall be adjusted as provided in Section 4.3 on the basis that the maximum number of Additional Shares issuable pursuant to all such warrants or other rights or necessary to effect the conversion or exchange of all such Convertible Securities shall be deemed to have been issued and outstanding and the Company shall have received all of the consideration payable therefor, if any, as of the date of the actual issuance of such warrants or other rights or Convertible Securities. No further adjustments of the number of Shares for which this Warrant is exercisable and the Exercise Price shall be made upon the actual issue of such Shares or of such Convertible Securities upon exercise of such warrants or other rights or upon the actual issue of such Shares upon such conversion or exchange of such Convertible Securities.

     4.5 Issuance of Convertible Securities. If, at any time, the Company shall take a record of holders of its Shares for the purpose of entitling them to receive a distribution of, or shall in any manner (whether directly or by assumption in a merger where the Company is the surviving entity) issue or sell, any Convertible Securities other than Permitted Shares, whether or not the rights to exchange or convert thereunder are immediately exercisable, and the price per Share for which Shares are issuable upon such conversion or exchange shall be less than the Exercise Price in effect immediately prior to the time of such issue or sale, then the number of Shares for which this Warrant is exercisable and the Exercise Price shall be adjusted as provided in Section 4.3 on the basis that the maximum number of Additional Shares necessary to effect the conversion or exchange of all such Convertible Securities shall be deemed to have been issued and outstanding and the Company shall have received all of the consideration payable therefor, if any, as of the date of actual issuance of such Convertible Securities. No adjustment of the number of Shares for which this Warrant is exercisable and the Exercise Price shall be made under this Section 4.5 upon the issuance of any Convertible Securities that are issued pursuant to the exercise of any warrants or other subscription or purchase rights therefor, if any such adjustment shall previously have been made upon the issuance of such warrants or other rights pursuant to Section 4.4. No further adjustments of the number of Shares for which this Warrant is exercisable and the Exercise Price shall be made upon the actual issue of such Shares upon conversion or exchange of such Convertible Securities and, if any issue or sale of such Convertible Securities is made upon exercise of any warrant or other right to subscribe for or to purchase any such Convertible Securities for which adjustments of the number of Shares for which this Warrant is exercisable and the Exercise Price have been or are to be made pursuant to other provisions of this Section 4, no further adjustments of the number of Shares for which this Warrant is exercisable and the Exercise Price shall be made by reason of such issue or sale.

     4.6 Superseding Adjustment. If, at any time after any adjustment of the number of Shares for which this Warrant is exercisable and the Exercise Price has been made pursuant to Section 4.4 or Section 4.5 as the result of any issuance of warrants, rights or Convertible Securities:

     (a) such warrants or rights, or the right of conversion or exchange in such other Convertible Securities, shall expire, and all or a portion of such warrants or rights, or the right of conversion or exchange with respect to all or a portion of such other Convertible Securities, as the case may be, shall not have been exercised, or

     (b) the consideration per Share for which Shares are issuable pursuant to such warrants or rights, or the terms of such other Convertible Securities, shall be increased solely by virtue of provisions therein contained for an automatic increase in such consideration per Share upon the occurrence of a specified date or event,

then for each outstanding Warrant such previous adjustments shall be rescinded and annulled and the Additional Shares that were deemed to have been issued by virtue of the computation made in connection with the adjustment so rescinded and annulled shall no longer be deemed to have been issued by virtue of such computation. Thereupon, a recomputation shall be made of the effect of such warrants or rights or options or other Convertible Securities on the basis of:

     (c) treating the number of Additional Shares or other property, if any, theretofore actually issued or issuable pursuant to the previous exercise of any such warrants or rights or any such right of conversion or exchange, as having been issued on the date or dates of any such exercise and for the consideration actually received and receivable therefor, and

     (d) treating any such warrants or rights or any such other Convertible Securities that then remain outstanding as having been granted or issued immediately after the time of such increase of the consideration per Share for which Shares or other property are issuable under such warrants or rights or other Convertible Securities, whereupon a new adjustment of the number of Shares for which this Warrant is exercisable and the Exercise Price shall be made, which new adjustment shall supersede the previous adjustment so rescinded and annulled.

     4.7 Other Provisions Applicable to Adjustments under this Section. The following provisions shall be applicable to making adjustments to the number of Shares for which this Warrant is exercisable and the Exercise Price provided for in this Section 4:

     (a) Computation of Consideration. To the extent that any Additional Shares or any Convertible Securities or any warrants or other rights to subscribe for or purchase any Additional Shares or any Convertible Securities are issued for cash consideration, the consideration received by Company therefor shall be the amount of the cash received by Company therefor, or, if such Additional Shares or Convertible Securities are offered by Company for subscription, the subscription price, or, if such Additional Shares or Convertible Securities are sold to underwriters or dealers for public offering without a subscription offering, the initial public offering price (in any such case subtracting any amounts paid or receivable for accrued interest or accrued distributions and without taking into account any compensation, discounts or expenses paid or incurred by Company for and in the underwriting of, or otherwise in connection with, the issuance thereof). To the extent that such issuance is for a consideration other than cash, then, except as herein otherwise expressly provided, the amount of such consideration shall be deemed to be the fair market value of such consideration at the time of such issuance as determined in good faith by the Board and supported by an opinion from an Independent Financial Expert. In case any Additional Shares or any

Convertible Securities or any warrants or other rights to subscribe for or purchase such Additional Shares or Convertible Securities shall be issued in connection with any merger where the Company issues any securities, the amount of consideration therefor shall be deemed to be the fair market value, as determined in good faith by the Board and supported by an opinion from an Independent Financial Expert of such portion of the assets and business of the nonsurviving entity as the Board in good faith shall determine to be attributable to such Additional Shares, Convertible Securities, warrants or other rights, as the case may be. The consideration for any Additional Shares issuable pursuant to any warrants or other rights to subscribe for or purchase the same shall be the consideration received by the Company for issuing such warrants or other rights plus the additional consideration payable to the Company upon exercise of such warrants or other rights. The consideration for any Additional Shares issuable pursuant to the terms of any Convertible Securities shall be the consideration received by the Company for issuing warrants or other rights to subscribe for or purchase such Convertible Securities, plus the consideration paid or payable to the Company in respect of the subscription for or purchase of such Convertible Securities, plus the additional consideration, if any, payable to the Company upon the exercise of the right of conversion or exchange of such Convertible Securities. If any Additional Shares or Convertible Securities are issued at any time in payment or satisfaction of any distributions upon any class of Shares other than Shares, Company shall be deemed to have received for such Additional Shares or Convertible Securities a consideration equal to the amount of such distribution so paid or satisfied.

     (b) When Adjustments to Be Made. The adjustments required by this Section 4 shall be made whenever and as often as any specified event requiring an adjustment shall occur, except that any adjustment of the number of Shares for which this Warrant is exercisable that would otherwise be required may be postponed (except in the case of a subdivision or combination of the Shares, as provided for in Section 4.1) up to, but not beyond the date of exercise if such adjustment either by itself or with other adjustments not previously made adds or subtracts less than 1% of the Shares for which this Warrant is exercisable immediately prior to the making of such adjustment. Any adjustment representing a change of less than such minimum amount (except as aforesaid) that is postponed shall be carried forward and made as soon as such adjustment, together with other adjustments required by this Section 4 and not previously made, would result in a minimum adjustment on the date of exercise. For the purpose of any adjustment, any specified event shall be deemed to have occurred at the close of business on the date of its occurrence.

     (c) Fractional Interests. In computing adjustments under this Section 4, fractional interests in Shares shall be taken into account to the nearest 1/100th of a Share.

     (d) When Adjustment Not Required. If the Company takes a record of holders of its Shares for the purpose of entitling them to receive a distribution or subscription or purchase rights and, thereafter and before the distribution to holders thereof, legally abandons its plan to pay or deliver such distribution, subscription or purchase rights, then thereafter no adjustment shall be required by reason of the taking of such record and any such adjustment previously made in respect thereof shall be rescinded and annulled.

     (e) Challenge to Good Faith Determination. Whenever the Board is required to make a determination in good faith of the fair market value of any item under this Section 4,

the Holder may challenge such determination in good faith, and an Independent Financial Expert shall resolve any such dispute.

Whenever the number of Shares for which this Warrant is exercisable, or whenever the price at which such Shares may be purchased upon exercise of the Warrants, is adjusted pursuant to Section 4, the Company shall prepare a certificate to be executed by its chief financial officer, if any, or its principal financial officers in case there is no chief financial officer, setting forth, in reasonable detail, the event requiring the adjustment and the method by which such adjustment was calculated (including a description of the basis on which the Board determined the fair market value of any evidences of indebtedness, Shares or stock, other securities or property or warrants or other subscription or purchase rights referred to in Section 4.2), specifying the number of Shares for which this Warrant is exercisable and describing the number and kind of any other Shares or other property for which this Warrant is exercisable, and any change in the purchase price or prices thereof, after giving effect to such adjustment or change. The Company shall promptly cause a signed copy of such certificate to be delivered to each Holder in accordance with Section 14.2. The Company shall keep at its office or agency designated pursuant to Section 12 copies of all such certificates and cause the same to be available for inspection at said office during normal business hours by any Holder or any prospective purchaser of a Warrant designated by a Holder thereof.

     5.2 Notice of Company Action. If at any time:

     (a) the Company takes a record of holders of its Shares for the purpose of entitling them to receive a distribution of any type including cash, property, or any right to subscribe for or purchase any evidences of its indebtedness, any Shares of any class or series or any other securities or property, or to receive any other right;

     (b) there is any capital reorganization of the Company, any reclassification or recapitalization of the Company or any consolidation or merger of the Company with, or any sale, transfer or other disposition of all or substantially all the property, assets or business of the Company to, another Person;

     (c) there is a voluntary or involuntary dissolution, liquidation or winding up of the Company.

then, in any one or more of such cases, the Company shall give to Holder: (i) at least twenty (20) days’ prior written notice of the date on which a record date shall be selected for such distribution or right or for determining rights to vote in respect of any such reorganization, reclassification, merger, consolidation, sale, transfer, disposition, dissolution, liquidation or winding up, and (ii) if any such reorganization, reclassification, merger, consolidation, sale, transfer, disposition, dissolution, liquidation or winding up occurs, at least twenty (20) days’ prior written notice of the date when the same shall take place. Such notice also shall specify: (i) the date on which any such record is to be taken for the purpose of such distribution or right, the date on which Holders of Shares shall be entitled to any such distribution or right, and the amount and character thereof, and (ii) the date on which any such reorganization,

reclassification, merger, consolidation, sale, transfer, disposition, dissolution, liquidation or winding up is to take place and the time, if any such time is to be fixed, as of which Holders of Shares shall be entitled to exchange their Shares for securities or other property deliverable upon such reorganization, reclassification, merger, consolidation, sale, transfer, disposition, dissolution, liquidation or winding up. Each such written notice shall be deemed sufficiently given if addressed to Holder at the last address of Holder appearing on the books of the Company and delivered in accordance with Section 14.2.

6. NO IMPAIRMENT. The Company shall not by any action, including, without limitation, through any amendment to its certificate of incorporation through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in carrying out all such actions as may be reasonably necessary or appropriate to protect the rights of Holder against impairment. Without limiting the generality of the foregoing, the Company will (a) take all such action as may be reasonably necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Shares upon the exercise of this Warrant, and (b) use its reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof as may be necessary to enable the Company to perform its obligations under this Warrant.

7. RESERVATION AND AUTHORIZATION OF SHARES. From and after the date hereof, the Company shall at all times reserve and keep available for issue upon the exercise of Warrants such number of its authorized but unissued Shares as will be sufficient to permit the exercise in full of all outstanding Warrants. All Shares, when issued upon exercise of any Warrant and payment therefor in accordance with the terms of such Warrant, shall be duly and validly issued and fully paid and nonassessable, and not subject to preemptive rights.

     Before taking any action that would result in an adjustment in the number of Shares for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

     If any Shares required to be reserved for issuance upon exercise of Warrants require registration or qualification with any governmental authority or other governmental approval or filing under any federal or state law before such Shares may be so issued, the Company will in good faith and as expeditiously as possible and at its expense endeavor to cause such Shares to be duly registered.

8. TAKING OF RECORD; SHARES AND WARRANT TRANSFER BOOKS. In the case of all distributions by the Company to holders of its Shares with respect to which any provision of Section 4 refers to the taking of a record of such holders, the Company will in each such case take such a record as of the close of business on a Business Day. The Company will not at any time, except upon dissolution, liquidation or winding up of the Company, close its transfer books so as to result in preventing or delaying the exercise or transfer of any Warrant.

9. RESTRICTIVE LEGEND. If certificated, each Share certificate representing Warrant Shares shall bear the following legends:

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL OR OTHER EVIDENCE SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED.

THE SALE, TRANSFER OR ASSIGNMENT OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN VOTING AGREEMENT, AS AMENDED FROM TIME TO TIME, AMONG THE COMPANY AND CERTAIN HOLDERS OF ITS OUTSTANDING CAPITAL STOCK. COPIES OF SUCH AGREEMENT MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE COMPANY.

Certificates evidencing the Warrant Shares shall not contain the legend set forth above: (i) following any sale of such Warrant Shares pursuant to an effective registration statement covering the resale of such security under the Securities Act, or (ii) following any sale of such Warrant Shares pursuant to Rule 144, or (iii) if requested by the Holder and such Warrant Shares are eligible for sale under Rule 144(k) (or any similar successor rule that may be promulgated by the Commission), or (iv) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission). The Company may not make any notation on its records that enlarge the restrictions on transfer set forth in this Section.

10. SUPPLYING INFORMATION. The Company shall cooperate with each Holder of a Warrant and each holder of Warrant Shares in supplying such information as may be reasonably necessary for such holder to complete and file any information reporting forms presently or hereafter required by the Commission as a condition to the availability of an exemption from the Securities Act for the sale or transfer of any Warrant or Warrant Shares.

11. LOSS OR MUTILATION. Upon receipt by the Company of evidence reasonably satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of any Warrant (which evidence shall be, in the case of an institutional investor, notice from such institutional investor of such ownership and such loss, theft, destruction or mutilation), and

     (a) in the case of loss, theft or destruction, of indemnity reasonably satisfactory to it (provided that if the Holder of such Warrant is an institutional investor or has a minimum net worth of at least $500,000,000, such Holder’s own unsecured agreement of indemnity shall be deemed to be satisfactory), or

     (b) in the case of mutilation, upon surrender and cancellation thereof,

the Company at its own expense shall execute and deliver, in lieu thereof, a new Warrant, dated the date of the original Warrant.

12. OFFICE OF THE COMPANY. As long as any of the Warrants remain outstanding, the Company shall maintain an office or agency (which may be the principal executive offices of the Company) where the Warrants may be presented for exercise, registration of transfer, division or combination as provided in this Warrant.

13. SECURITIES ACT MATTERS.

     13.1 Representations, Warranties and Covenants of Holder. The Holder hereby represents and warrants to, and agrees with, the Company as of the date of any exercise hereof that:

     (a) It is acquiring the Warrant Shares, for its own account, without a view to the distribution thereof in violation of the Securities Act, without prejudice, however, to Holder’s right to Transfer the Warrant Shares in compliance with applicable securities laws and the terms of the Stockholders Agreements.

     (b) It is an “accredited investor” within the meaning of Regulation D under the Securities Act.

     (c) It acknowledges that (i) the Warrant Shares have not been registered under the Securities Act, in reliance on the private offering exemption contained in Section 4(2) of the Securities Act and Regulation D thereunder; (ii) because the Warrant Shares are not so registered, it must bear the economic risk of holding the Warrant Shares for an indefinite period of time unless the Warrant Shares are subsequently, registered under the Securities Act or an exemption from such registration is available with respect thereto; and (iii) there is no trading market for the Warrant Shares and there is no expectation that such market will exist in the future.

     (d) It will not assign or transfer the Warrant Shares except in accordance and in compliance with the requirements of the Securities Act, as then in effect.

     (e) It acknowledges that (i) it has had ready access to any and all documents which it deems relevant to the acquisition of the Warrant Shares; (ii) the Company has made available to it at a reasonable time prior to the issuance of the Warrant Shares the opportunity to ask questions and receive answers concerning the Company and to obtain any additional information which the Company possesses or can be acquired without unreasonable effort or expense that is necessary to verify the accuracy of the information furnished by the Company; and (iii) it has reviewed or had the opportunity to review all such documents or information referred to above.

     13.2 Representations, Warranties and Covenants of the Company. The Company represents and warrants to, and agrees with, Holder as of the date of any exercise that:

     (a) This Warrant has been duly authorized, validly issued and is the valid and binding obligation of the Company, enforceable against the Company in accordance with the terms hereof.

     (b) Assuming the truth and accuracy of Holder’s representations and warranties contained in Section 13.1, the issuance of this Warrant and the issuance of Warrant Shares pursuant to this Warrant are exempt from the registration and prospectus delivery requirements of the Securities Act.

     (c) The Company agrees that neither it nor any Person acting on its behalf has offered or will offer this Warrant or the Warrant Shares or any part thereof or any similar securities for issue or sale to, or has solicited or will solicit any offer to acquire any of the same from, any Person so as to bring the issuance and sale of this Warrant or the Warrant Shares hereunder within the provisions of the registration and prospectus delivery requirements of the Securities Act.

14. MISCELLANEOUS

     14.1 Nonwaiver and Expenses. If either party (the “Defaulting Party”) fails to comply with any provision of this Warrant, it shall pay to the other party such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings, incurred by the other party in enforcing any of its rights, powers or remedies hereunder. No course of dealing or any delay or failure to exercise any right hereunder on the part of a party shall operate as a waiver of such right or otherwise prejudice its rights, powers or remedies.

     14.2 Notice Generally. Any notice, demand, request, consent, approval, declaration, delivery or other communication to be made pursuant to the provisions of this Warrant shall be deemed sufficiently given or made if in writing and either delivered in person with receipt acknowledged or sent by registered or certified mail, return receipt requested, postage prepaid, or by telecopy and confirmed by telecopy answerback, addressed as follows:

     (a) If to any Holder or holder of Warrant Shares, at its last known address appearing on the books of the Company maintained for such purpose.

deemed to have been duly given or served on the date on which personally delivered, with receipt acknowledged, telecopied and confirmed by telecopy answerback, or three (3) Business Days after the same shall have been deposited in the United States mail. Notice by electronic mail shall not constitute effective notice hereunder.

     14.3 Successors and Assigns. Subject to the provisions of Sections 3.1, this Warrant and the rights evidenced hereby shall inure to the benefit of and be binding upon the successors of the Company and the successors and assigns of Holder. Holder has entered into the Stockholders Agreements with the Company and other members which imposes certain other restrictions on the transfer of the Warrant Shares. This Warrant and all rights evidenced hereby may be transferred by Holder to any Person in accordance with the terms of the Stockholders Agreements and law, including without limitation, the Securities Act.

     14.4 Remedies. Subject to the terms of the Stockholders Agreements, each holder of a Warrant or Warrant Shares, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by the Company of the provisions of this Warrant and hereby agrees to waive the defense in any action for specific performance that a remedy at law would be adequate.

     14.5 Amendment. This Warrant may be modified, restated, supplemented, waived or amended or the provisions hereof waived with the written consent of the Company and Holder.

     14.6 Severability. Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Warrant.

     14.7 Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.

     14.8 Governing Law. This Warrant shall be governed by the laws of the State of New York, without regard to the provisions thereof relating to conflict of laws.

     14.11 Counterparts. This Warrant may be executed by one or more of the parties to this Warrant on any number of separate counterparts, and all of said counterparts taken together shall be deemed to constitute one and the same instrument.

     14.12 Reorganization of the Company or Reclassification of Shares. In the event the Company (a) converts, by merger or otherwise, to another type of entity including but not limited to a corporation or a limited partnership, or (b) reclassifies the Shares into any other class of equity (the result of such reclassification, “Reclassified Shares”), then Holder will be entitled to purchase the percentage of such Fully Diluted Outstanding (x) equity interests in such entity or (y) Reclassified Shares, as applicable, equal to the percentage of Fully Diluted Outstanding Shares provided for by, and on the same terms and conditions specified in, this Warrant.

15. LIMITATION OF LIABILITY.
