Domestic Capital Funding, Ltd., a Cayman Islands limited company (collectively and together with each of their respective successors and assigns, the “Purchasers”). Capitalized terms shall have the meaning specified in Section 5.1 hereof.

RECITALS

     WHEREAS, pursuant to the Merger Agreement, the Purchasers have agreed to acquire from the Company, and the Company has agreed to issue to the Purchasers, Warrants to purchase the number of shares of Common Stock set forth opposite such Person’s name on Annex 1 attached hereto, which Warrants represent the right to purchase, in the aggregate, 3,400,945 shares of Common Stock, subject to adjustment as set forth herein; and

     WHEREAS, the Company and the Purchasers wish to enter into this Agreement to govern the terms of the Warrants.

AGREEMENT

     NOW, THEREFORE, in consideration of the premises and the mutual agreements set forth herein, the parties to this Agreement hereby agree as follows:

1. FORM, EXECUTION AND TRANSFER OF WARRANT CERTIFICATES.

     1.1. Form of Warrant Certificates.

     The Warrant Certificates shall be in the form set forth in Attachment A hereto. The Warrant Certificates may have such letters, numbers or other marks of identification or designation as may be required to comply with any law or with any rule or regulation of any governmental authority, stock exchange or self-regulatory organization made pursuant thereto (“Law”). Each Warrant Certificate shall be dated the date of issuance thereof by the Company, either upon initial issuance or upon transfer or exchange. Each Warrant Certificate shall represent the right to purchase the number of shares of Common Stock set forth in such Warrant

Certificate at a price per share of Common Stock equal to the Exercise Price; provided, that the number of shares of Common Stock issuable upon exercise of the Warrants and the Exercise Price thereof shall be subject to adjustment as provided herein.

1.2.

Execution of Warrant Certificates; Registration Books.

     (a) Execution of Warrant Certificates. The Warrant Certificates shall be executed on behalf of the Company by an officer of the Company authorized by the Board of Directors. In case the officer of the Company who shall have signed any Warrant Certificate shall cease to be such an officer of the Company before issuance and delivery by the Company of such Warrant Certificate, such Warrant Certificate nevertheless may be issued and delivered with the same force and effect as though the individual who signed such Warrant Certificate had not ceased to be such an officer of the Company, and any Warrant Certificate may be signed on behalf of the Company by any individual who, at the actual date of the execution of such Warrant Certificate, shall be a proper officer of the Company to sign such Warrant Certificate, although at the date of the execution of this Agreement any such individual was not such an officer.

     (b) Registration Books. The Company will keep or cause to be kept at its office, maintained at the address of the Company referenced in Section 6.6, at the Company’s transfer agent, or at such other office of the Company of which the Company shall have given notice to each holder of Warrant Certificates, books for registration and transfer of the Warrant Certificates issued hereunder. Such books shall show the names and addresses of the respective holders of the Warrant Certificates, the registration number and date of each of the Warrant Certificates and the Denomination thereof.

     1.3. Transfer, Split Up, Combination and Exchange of Warrant Certificates; Lost or Stolen Warrant Certificates.

     (a) Transfer, Split Up, etc.

          (i) Transfer. Subject to compliance with the Securities Act, any applicable state securities laws and the Stockholders’ Agreement, any Warrant Certificate (or portion thereof), with or without other Warrant Certificates, may be transferred to any Person for a Warrant Certificate or Warrant Certificates in an aggregate like Denomination as the Warrant Certificate or Warrant Certificates (or portions thereof) surrendered then entitled such registered holder to purchase. Any registered holder desiring to transfer any Warrant Certificate shall make such request in writing delivered to the Company, which request shall include the identity of the Transferee and the aggregate number of Warrants to be transferred, and shall surrender the Warrant Certificate or Warrant Certificates

(or portions thereof) to be transferred at the office of the Company referenced in Section 6.6, whereupon the Company shall deliver promptly to such Transferee a Warrant Certificate or Warrant Certificates, as the case may be, as so requested, which Warrant Certificate or Warrant Certificates shall evidence, collectively, the same aggregate number of Warrants as the Warrant Certificate or Warrant Certificates (or portions thereof) so surrendered for transfer and shall issue a new Warrant Certificate to the transferor representing the Warrants retained by the Transferor if such transfer involved less than the entire number of Warrants held by such Transferor.

          (ii) Split Up, Combination, Exchange, etc. Any Warrant Certificate, with or without other Warrant Certificates, may be split up, combined or exchanged for another Warrant Certificate or Warrant Certificates, in an aggregate like Denomination as the Warrant Certificate or Warrant Certificates surrendered then entitle such registered holder to purchase. Any registered holder desiring to split up, combine or exchange any Warrant Certificate shall make such request in writing delivered to the Company, and shall surrender the Warrant Certificate or Warrant Certificates to be split up, combined or exchanged at the office of the Company referenced in Section 6.6, whereupon the Company shall deliver promptly to such registered holder a Warrant Certificate or Warrant Certificates, as the case may be, as so requested, which Warrant Certificate or Warrant Certificates shall evidence, collectively, the same aggregate Denomination as the Warrant Certificate or Warrant Certificates so surrendered for split-up, combination or exchange.

     (b) Loss, Theft, etc. 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 Certificate, and:

     (i) in the case of loss, theft or destruction, an affidavit of loss, together with a customary and reasonable indemnity; or

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

the Company at its own expense will execute and deliver, in lieu thereof, a new Warrant Certificate, dated the date of such lost, stolen, destroyed or mutilated Warrant Certificate and of like tenor, in lieu of the lost, stolen, destroyed or mutilated Warrant Certificate and evidencing the same Denomination as the Warrant Certificate so lost, stolen, destroyed or mutilated.

     1.4. Subsequent Issuance of Warrant Certificates.

Subsequent to the original issuance, no Warrant Certificates shall be issued except:

     (a) Warrant Certificates issued upon any transfer, combination, split up or exchange of Warrants pursuant to Section 1.3(a);

     (b) Warrant Certificates issued in replacement of mutilated, destroyed, lost or stolen Warrant Certificates pursuant to Section 1.3(b);

     (c) Warrant Certificates issued pursuant to Section 2.3 upon the partial exercise of any Warrant Certificate to evidence the unexercised portion of such Warrant Certificate; and

     (d) Warrant Certificates to reflect any adjustments pursuant to Section 4.

     1.5. Effect of Issuance in Registered Form.

     Every holder of a Warrant Certificate by accepting the same consents and agrees with the Company and with every other holder of a Warrant Certificate that:

     (a) the Warrant Certificates, to the extent then currently transferable, are transferable only on the registry books of the Company if and when surrendered at the office of the Company referenced in Section 6.6, duly endorsed or accompanied by an instrument of transfer (in the form attached thereto) and payment of any applicable transfer, stamp or issue tax (a “Tax”); and

     (b) the Company may deem and treat the Person in whose name each Warrant Certificate is registered as the absolute owner thereof and of the Warrants evidenced thereby (notwithstanding any notations of ownership or writing on the Warrant Certificates made by anyone other than the Company) for all purposes whatsoever, and the Company shall not be affected by any notice to the contrary.

2. EXERCISE OF WARRANTS; PAYMENT OF EXERCISE PRICE.

     2.1. Exercise of Warrants.

     (a) Manner of Exercise. At any time and from time to time prior to the Expiration Time, the holder of any Warrant Certificate may exercise the Warrants evidenced thereby, in whole or in any part, by surrender to the Company, at its office referenced in Section 6.6, of such Warrant Certificate, together with a duly executed election to purchase (a form of which is attached to each Warrant Certificate) and payment of the applicable Exercise Price for each share of Common Stock with respect to which the Warrants are then being exercised and an amount equal to any applicable Tax (if not payable by the Company as provided in Section 3.3). Such Exercise Price shall be payable either:

	(i)		in cash pursuant to Section 2.1(b); or
	(ii)		by delivery of Warrant Certificates pursuant to Section 2.1(c).

     (b) Payment in Cash. Upon exercise of any Warrants, the holder of a Warrant Certificate may pay the Exercise Price by certified or official bank check payable to the order of the Company or by wire transfer of immediately available funds to the account of the Company.

     (c) Net Exercise. In the event that any holder of Warrant Certificates delivers such Warrant Certificates to the Company and notifies the Company in writing that such holder intends to exercise all, or any portion of, the Warrants represented by such Warrant Certificates to satisfy its obligation to pay the Exercise Price in respect thereof by virtue of the provisions of this Section 2.1(c), such holder shall become entitled to receive, instead of the number of shares of Common Stock such holder would have received had the Exercise Price been paid pursuant to Section 2.1(b), a number of shares of Common Stock in respect of the exercise of such Warrants equal to the product of:

     (i) the number of shares of Common Stock issuable upon such exercise of such Warrant Certificate (or, if only a portion of such Warrant Certificate is being exercised, issuable upon the exercise of such portion); multiplied by

     (ii) the quotient of:

     (A) the difference of:

     (I) the Market Price per share of Common Stock at the time of such exercise; minus

     (II) the Exercise Price per share of Common Stock at the time of such exercise;

divided by

     (B) the Market Price per share of Common Stock at the time of such exercise.

     (d) Fractional shares of Common Stock. The Company may, in accordance with Section 2.6, pay the exercising holder cash in lieu of issuing a fractional share in connection with an exercise of Warrants; provided that, if it does not issue a fractional share in such circumstances, it will make such cash payment.

     (e) Automatic Exercise. Notwithstanding anything herein to the contrary, any Warrants issued hereunder shall be fully exercised pursuant to Section 2.1(c), without the need for any action by the holder thereof or the Company, immediately prior to the Expiration Time, provided that upon such automatic exercise the resulting value is greater than zero.

     2.2. Issuance of Common Stock.

     Upon timely receipt of a Warrant Certificate, accompanied by the form of election to purchase duly executed, and payment of the Exercise Price for each of the shares of the Common Stock to be purchased (if payable in the manner provided in Section 2.1(a)(i)) and by an amount equal to any applicable Tax (if not payable by the Company as provided in Section 3.3), the Company shall thereupon promptly cause certificates representing the number of whole shares of

Common Stock then being purchased to be delivered to or upon the order of the registered holder of such Warrant Certificate, registered in such name or names as may be designated by such holder, and, promptly after such receipt deliver the cash, if any, to be paid in lieu of fractional shares pursuant to Section 2.6 to or upon the order of the registered holder of such Warrant Certificate.

     2.3. Unexercised Warrants.

     In the event that the registered holder of any Warrant Certificate shall exercise less than all the Warrants evidenced thereby, a new Warrant Certificate evidencing Warrants equal in number to the number of Warrants remaining unexercised shall be issued by the Company to the registered holder of such Warrant Certificate or to its duly authorized assigns.

     2.4. Cancellation and Destruction of Warrant Certificates.

     All Warrant Certificates surrendered to the Company for the purpose of exercise, exchange, substitution or transfer shall be cancelled by it, and no Warrant Certificates shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Agreement. The Company shall cancel and retire any other Warrant Certificates purchased or acquired by the Company otherwise than upon the exercise thereof.

     2.5. Expiration.

     All Warrants that have not been exercised or purchased in accordance with the provisions of this Agreement shall expire and all rights of holders of such Warrants shall terminate and cease at the Expiration Time.

     2.6. Fractional shares of Common Stock.

     The Company shall not be required to issue fractional shares of Common Stock upon the exercise of any Warrant. If fractional shares are not issued upon the exercise of any Warrant, there shall be paid to the holder thereof, in lieu of any fractional share of Common Stock resulting therefrom, an amount of cash equal to the product of:

     (a) the fractional amount of such share of Common Stock; and

     (b) the Market Price, as determined on the trading day immediately prior to the date of exercise of such Warrant.

3. AGREEMENTS OF THE COMPANY.

     3.1. Reservation of Common Stock.

     The Company covenants and agrees that it will at all times cause to be reserved and kept available out of its authorized and unissued shares or treasury shares of Common Stock such number of shares of Common Stock as will be sufficient to permit the exercise in full of all Warrants issued hereunder into Common Stock.

3.2.

Common Stock To Be Duly Authorized and Issued, Fully Paid and Nonassessable etc; Compliance with Law

     The Company covenants and agrees that it will take all such action as may be necessary to ensure that all shares of Common Stock delivered upon the exercise of any Warrant and the payment of the Exercise Price pursuant to Section 2.1 (in each case, at the time of delivery of the certificates representing such shares of Common Stock) shall (a) be duly and validly authorized and issued and fully paid and nonassessable, free of any preemptive rights in favor of any Person in respect of such issuance and free of any security interest, pledge, mortgage, lien, charge or other encumbrance created by, or arising out of actions of, the Company (other than such rights and security interests, pledges, mortgages, liens, charges, or other encumbrances, if any, arising out of the provisions of this Agreement or the Stockholders’ Agreement) and (b) be issued without violation of any applicable Law.

     3.3. Taxes.

     The Company covenants and agrees that it will pay when due and payable any and all Taxes and charges that may be payable in respect of the initial issuance or delivery of:

     (a) each Warrant Certificate;

     (b) each Warrant Certificate issued in exchange for any other Warrant Certificate pursuant to Section 1.3, Section 2.3 or Section 4; and

     (c) each share of Common Stock issued upon the exercise of any Warrant.

     The Company shall not, however, be required to:

     (i) pay any Tax that may be payable in respect of the transfer or delivery of Warrant Certificates in a name other than that of the registered holder of the Warrant Certificate surrendered for exercise, conversion, transfer or exchange (any such Tax being payable by the holder of such certificate at the time of surrender); or

     (ii) issue or deliver any such certificates referred to in the foregoing clause (i) until any such Tax referred to in the foregoing clause (i) shall have been paid.

     3.4. Common Stock Record Date.

     Each Person in whose name any certificate for shares of Common Stock is issued upon the exercise of Warrants shall for all purposes be deemed to have become the holder of record of the Common Stock represented thereby on, and such certificates (if any) shall be dated, the date upon which the Warrant Certificate evidencing such Warrants was duly surrendered with an election to purchase attached thereto duly executed and payment of the aggregate Exercise Price (and any applicable Taxes, if payable by such Person) was made.

     3.5. Rights in Respect of Common Stock.

     Except as otherwise set forth herein or in the Stockholders’ Agreement, prior to the exercise of the Warrants evidenced thereby, the holder of a Warrant Certificate shall not be entitled to any rights of a stockholder of the Company with respect to the Common Stock into which the Warrants shall be exercisable, including, without limitation, the right to vote in respect of any matter upon which the holders of Common Stock may vote, the right to receive any distributions of cash or property and, except as expressly set forth herein, in the Merger Agreement, in the Stockholders’ Agreement or in this Agreement, the right to receive any notice of any proceedings of the Company. Prior to the exercise of the Warrants evidenced thereby, the holders of the Warrant Certificates shall not have as such any obligation in respect of any assessment or any other obligation or liability as a stockholder of the Company, whether such obligations or liabilities are asserted by the Company or by creditors of the Company, but shall have the obligations set forth in the Stockholders’ Agreement.

     3.6. Noncircumvention.

     The Company hereby covenants and agrees that the Company will not, by amendment of its charter, bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, 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 Agreement, and will at all times in good faith carry out all the provisions of this Warrant Agreement.

4. ANTI-DILUTION ADJUSTMENTS.

     4.1. Adjustments.

     The number of shares of Common Stock purchasable upon the exercise of each Warrant, and the Exercise Price, shall be subject to adjustment as set forth in this Section 4.

     4.2. Stock Splits, Subdivisions, Reclassifications or Combinations.

     If the Company shall (i) declare and pay a dividend or make a distribution on its Common Stock in shares of Common Stock, (ii) subdivide or reclassify the outstanding shares of Common Stock into a greater number of shares, or (iii) combine or reclassify the outstanding shares of Common Stock into a smaller number of shares, the number of shares of Common Stock issuable upon exercise of any Warrants at the time of the record date for such dividend or effective date of such split, reverse split, subdivision, combination or reclassification shall be proportionately adjusted so that the holder of such Warrants after such date shall be entitled to purchase the number of shares of Common Stock which such holder would have owned or been entitled to receive in respect of the shares of Common Stock subject to such Warrants after such date had such Warrants been exercised immediately prior to such date. In such event, the Exercise Price in effect at the time of the effective date of such split, reverse split, subdivision, combination or reclassification shall be adjusted to the number obtained by dividing (x) the product of (1) the number of shares of Common Stock issuable upon the exercise of such Warrants before such adjustment and (2) the Exercise Price in effect immediately prior to the

record or effective date, as the case may be, for the dividend, distribution, split, reverse split, subdivision, combination or reclassification giving rise to this adjustment by (y) the new number of shares of Common Stock issuable upon exercise of such Warrants determined pursuant to the immediately preceding sentence; provided that the Exercise Price shall not be adjusted to be less than the par value of the Common Stock.

     4.3. Price Based Anti-Dilution

     (a) Without duplication of the adjustments set forth in Sections 4.2 or 4.4, (a) if the Company shall issue or sell any shares of Common Stock (as actually issued or, pursuant to Section 4.3(b), deemed to be issued) for a consideration per share less than 90% of the Market Price per share immediately prior to such issuance or sale, or if earlier, upon the execution of the definitive documentation with respect to such issuance or sale (the “Effective Time”), then immediately upon the Effective Time the number of shares of Common Stock issuable upon exercise of any Warrants at the time of the effective date shall be increased by multiplying such number of shares of Common Stock by a fraction, (i) the numerator of which shall be the Fully Diluted Number of shares of Common Stock outstanding immediately prior to the Effective Time plus the number of shares of Common Stock so issued or sold, and (ii) the denominator of which shall be the Fully Diluted Number of shares of Common Stock outstanding immediately prior to the Effective Time plus the number of shares of Common Stock which the aggregate consideration received by the Company for the total number of shares of Common Stock so issued or sold would purchase if such shares were sold at Market Price. For the purposes of this Section 4.3(a), none of the following issuances shall be considered the issuance or sale of Common Stock:

     (i) the issuance of Common Stock upon the conversion of any then-outstanding Common Stock Equivalents;

     (ii) the issuance of any Common Stock or Common Stock Equivalents for which the adjustment provided in Section 4.2 applies;

     (iii) the issuance of shares of Common Stock or Common Stock Equivalents to Employees of the Company or any Company Subsidiary that is approved by the Board of Directors; or

     (iv) the issuance of Common Stock pursuant to the terms of the Amended and Restated Rights Agreement, dated as of December 3, 2002, between the Company and American Stock Transfer and Trust Company LLC, as amended December 13, 2006, March 4, 2009 and January 24, 2010.

     (b) For the purposes of Section 4.3(a), the following subparagraphs (i) to (iii), inclusive, shall also be applicable:

     (i) If the Company shall grant any rights to subscribe for, or any rights or options to purchase, Common Stock Equivalents, whether or not such rights or options or the right to convert or exchange any such Common Stock Equivalents

are immediately exercisable, and the price per share for which Common Stock is issuable upon the exercise of such rights or options or upon conversion or exchange of such Common Stock Equivalents (determined by dividing (A) the total amount, if any, received or receivable by the Company as consideration for the granting of such rights or options, plus the minimum aggregate amount of additional consideration payable to the Company upon the exercise of such rights or options, plus, in the case of any such rights or options which relate to such Common Stock Equivalents, the minimum aggregate amount of additional consideration, if any, payable upon the issue or sale of such Common Stock Equivalents and upon the conversion or exchange thereof, by (B) the total maximum number of shares of Common Stock issuable upon the exercise of such rights or options or upon the conversion or exchange of all such Common Stock Equivalents issuable upon the exercise of such rights or options) shall be less than the Market Price per share of Common Stock immediately prior to the time of the granting of such rights or options, or, if earlier, the execution of definitive documentation with respect to such grant, then the total maximum number of shares of Common Stock issuable upon the exercise of such rights or options or upon conversion or exchange of the total maximum amount of such Common Stock Equivalents issuable upon the exercise of such rights or options shall (as of the date of granting of such rights or options) be deemed to be outstanding and to have been issued for such price per share; provided that no further adjustment of the conversion price pursuant to this Section 4.3(b)(i) shall be made (i) upon the actual issuance or sale of such Common Stock Equivalents upon the exercise of any rights to subscribe for, or any rights or options to purchase, such Common Stock Equivalents or (ii) upon the actual issuance or sale of such Common Stock upon the exercise of any such Common Stock Equivalents, including without limitation, in each case of clauses (i) and (ii) with respect to shares of Common Stock Equivalents or Common Stock issued or issuable as a result of the effect of antidilution adjustments under any such security.

     (ii) If the Company shall issue or sell any Common Stock Equivalents, whether or not the rights to exchange or convert thereunder are immediately exercisable, and the price per share for which Common Stock is issuable upon such conversion or exchange (determined by dividing (A) the total amount received or receivable by the Company as consideration for the issue or sale of such Common

Stock Equivalents, plus the minimum aggregate amount of additional consideration, if any, payable to the Company upon the conversion or exchange thereof, by (B) the total maximum number of shares of Common Stock issuable upon the conversion or exchange of all such Common Stock Equivalents) shall be less than the Market Price per share of Common Stock immediately prior to the Effective Time, then the total maximum number of shares of Common Stock issuable upon conversion or exchange of such Common Stock Equivalents shall (as of the date of the issue or sale of such Common Stock Equivalents) be deemed to be outstanding and to have been issued for such price per share, provided that no further adjustment of the conversion price pursuant to this Section 4.3(b)(ii) shall be made upon the actual issuance or sale of such Common Stock upon the exercise of any such Common Stock Equivalents, including without limitation, in each case with respect to shares of Common Stock issued or issuable as a result of the effect of antidilution adjustments under any such security.

     (iii) In case at any time any shares of Common Stock or Common Stock Equivalents or any rights or options to purchase any such Common Stock, or Common Stock Equivalents shall be issued or sold for cash, the consideration received therefor shall be deemed to be the amount received by the Company therefor. In case any shares of Common Stock or Common Stock Equivalents or any rights or options to purchase any such Common Stock or Common Stock Equivalents shall be issued or sold for a consideration other than cash, the amount of the consideration other than cash received by the Company shall be deemed to be the Fair Market Value of such consideration.

     4.4. Other Distributions.

     In case the Company shall fix a record date for the making of a dividend or distribution to all holders of shares of its Common Stock of securities, evidences of indebtedness, assets, cash, rights or warrants (excluding dividends of its Common Stock and other dividends or distributions referred to in Section 4.2), in each such case, the Exercise Price in effect prior to such record date shall be reduced immediately thereafter to the price determined by multiplying the Exercise Price in effect immediately prior to the reduction by the quotient of (x) the Market Price of the Common Stock on the last trading day preceding the first date on which the Common Stock trades on the Exchange on which the Common Stock is listed or admitted to trading without the right to receive such distribution, minus the amount of cash and/or the Fair Market Value of the securities, evidences of indebtedness, assets, rights or warrants to be so distributed in respect of one share of Common Stock (such amount and/or Fair Market Value, the “Per Share Fair Market Value”) divided by (y) such Market Price on such date specified in clause (x); such adjustment shall be made successively whenever such a record date is fixed. In such event, the number of shares of Common Stock issuable upon the exercise of any Warrants shall be increased to the number obtained by dividing (x) the product of (1) the number of shares of Common Stock issuable upon the exercise of such Warrants before such adjustment, and (2) the Exercise Price in effect immediately prior to the distribution giving rise to this adjustment by (y) the new Exercise Price determined in accordance with the immediately preceding sentence. In the event that such distribution is not so made, the Exercise Price and the number of shares of Common Stock issuable upon exercise of such Warrants then in effect shall be readjusted, effective as of the date when the Board of Directors determines not to distribute such shares, evidences of indebtedness, assets, rights, cash or warrants, as the case may be, to the Exercise Price that would then be in effect and the number of shares of Common Stock that would then be issuable upon exercise of such Warrants if such record date had not been fixed.

     4.5. Business Combinations.

     In case of any Business Combination or reclassification of Common Stock (other than a reclassification of Common Stock referred to in Section 4.2), a holder’s right to receive shares of

Common Stock upon exercise of any Warrants shall be converted into the right to exercise such Warrant to acquire the number of shares of stock or other securities or property (including cash) which the Common Stock issuable (at the time of such Business Combination or reclassification) upon exercise of such Warrants immediately prior to such Business Combination or reclassification would have been entitled to receive upon consummation of such Business Combination or reclassification; and in any such case, if necessary, the provisions set forth herein with respect to the rights and interests thereafter of such holder shall be appropriately adjusted so as to be applicable, as nearly as may reasonably be, to such holder’s right to exercise such Warrants in exchange for any shares of stock or other securities or property pursuant to this Section 4.5. In determining the kind and amount of stock, securities or the property receivable upon exercise of any Warrants following the consummation of such Business Combination, if the holders of Common Stock have the right to elect the kind or amount of consideration receivable upon consummation of such Business Combination, then the holder of such Warrants shall be entitled to elect the kind or amount of consideration receivable upon consummation of such Business Combination. The Company shall not enter into or be party to any Business Combination unless the successor of the Company (if any), assumes in writing all of the obligations of the Company under this Warrant Agreement pursuant to written agreements, including agreements to deliver to each holder of Warrants hereunder in exchange for such Warrants a security of such successor evidenced by a written instrument substantially similar in form and substance to this Warrant Agreement.

4.6.

Expiration of Rights or Options.

     Upon the expiration of any rights or options to subscribe for, purchase or convert or exchange Common Stock or Common Stock Equivalents in respect of the issuance, sale or grant of which adjustment was made pursuant to Section 4.3, without the exercise thereof, the Exercise Price and the number of shares of Common Stock purchasable upon the exercise of each Warrant shall, upon such expiration, be readjusted and shall thereafter be such Exercise Price and such number of shares of Common Stock as would have been had such Exercise Price and such number of shares of Common Stock not been originally adjusted (or had the original adjustment not been required, as the case may be), as if:

     (a) the only shares of Common Stock so issued were the shares of Common Stock, if any, actually issued or sold upon the exercise of such rights or options; and

     (b) such shares of Common Stock, if any, were issued or sold for the consideration actually received by the Company upon such exercise plus the aggregate consideration, if any, actually received by the Company for the issuance, sale or grant of all of such rights or options, whether or not exercised; provided that no such readjustment shall have the effect of increasing the Exercise Price by an amount in excess of the amount of the reduction initially made in respect of the issuance, sale, or grant of such rights or options.

     4.7. Rounding of Calculations; Minimum Adjustments.

     All calculations under this Section 4 shall be made to the nearest one-tenth (1/10th) of a cent or to the nearest one-hundredth (1/100th) of a share, as the case may be. Any provision of this Section 4 to the contrary notwithstanding, no adjustment in the Exercise Price or the number of shares of Common Stock into which any Warrants are exercisable shall be made if the amount of such adjustment would be less than $0.01 or one-tenth (1/10th) of a share of Common Stock, but any such amount shall be carried forward and an adjustment with respect thereto shall be made at the time of and together with any subsequent adjustment which, together with such amount and any other amount or amounts so carried forward, shall aggregate $0.01 or 1/10th of a share of Common Stock, or more.

     4.8. Timing of Issuance of Additional Common Stock Upon Certain Adjustments.

     In any case in which the provisions of this Section 4 shall require that an adjustment shall become effective immediately after a record date for an event, the Company may defer until the occurrence of such event (i) issuing to the holder of any Warrants exercised after such record date and before the occurrence of such event the additional shares of Common Stock issuable upon such exercise by reason of the adjustment required by such event over and above the shares of Common Stock issuable upon such exercise before giving effect to such adjustment and (ii) paying to such holder any amount of cash in lieu of a fractional share of Common Stock; provided, however, that the Company upon request shall deliver to such holder a due ▇▇▇▇ or other appropriate instrument evidencing such holder’s right to receive such additional shares, and such cash, upon the occurrence of the event requiring such adjustment.

     4.9. Miscellaneous.

     (a) Statement Regarding Adjustments. Whenever the Exercise Price or the number of shares of Common Stock into which any Warrants are exercisable shall be adjusted as provided in Section 4, the Company shall forthwith file at the principal office of the Company referenced in Section 6.6 a statement showing in reasonable detail the facts requiring such adjustment and the Exercise Price that shall be in effect and the number of shares of Common Stock into which such Warrants shall be exercisable after such adjustment, and the Company shall also cause a copy of such statement to be sent by mail, first class postage prepaid, to each holder of Warrants at the address appearing in the Company’s records.

     (b) Notice of Adjustment Event. In the event that the Company shall propose to take any action of the type described in this Section 4 (but only if the action of the type described in this Section 4 would result in an adjustment in the Exercise Price or the number of shares of Common Stock into which Warrants are exercisable or a change in the type of securities or property to be delivered upon exercise of Warrants), the Company shall give notice to the holders of Warrants, in the manner set forth in Section 4.9(a), which notice shall specify the record date, if any, with respect to any such action and the approximate date on which such action is to take place. Such notice shall also set forth the facts with respect thereto as shall be reasonably necessary to indicate the

effect on the Exercise Price and the number, kind or class of shares or other securities or property which shall be deliverable upon exercise of any Warrants. In the case of any action which would require the fixing of a record date, such notice shall be given at least 10 days prior to the date so fixed, and in case of all other action, such notice shall be given at least 15 days prior to the taking of such proposed action. Without limiting the foregoing, to the extent notice of any of the foregoing actions or events is given to the holders of the Common Stock, such notice shall be provided to the holders of the Warrants on or before such notice to the holders of Common Stock.

     (c) Proceedings Prior to Any Action Requiring Adjustment. As a condition precedent to the taking of any action which would require an adjustment pursuant to this Section 4, the Company shall take any action which may be necessary, including obtaining regulatory, New York Stock Exchange, NASDAQ Stock Market or other applicable national securities exchange (an “Exchange”) or stockholder approvals or exemptions, in order that the Company may thereafter validly and legally issue as fully paid and nonassessable all shares of Common Stock that the holders are entitled to receive upon exercise of this any Warrants pursuant to this Section 4.

     (d) Adjustment Rules. Any adjustments pursuant to this Section 4 shall be made successively whenever an event referred to herein shall occur. If more than one subsection of this Section 4 is applicable to a single event, the subsection shall be applied that produces the largest adjustment and no single event shall cause an adjustment under more than one subsection of this Section 4 so as to result in duplication. If an adjustment in Exercise Price made hereunder would reduce the Exercise Price to an amount below par value of the Common Stock, then such adjustment in Exercise Price made hereunder shall reduce the Exercise Price to the par value of the Common Stock.
