Poniard hereby grants and Verastem accepts, subject to the terms and conditions of this Agreement and Sections 2.4 and 2.5, an exclusive, worldwide license (with right to sublicense as permitted under Section 2.2.1) under the Licensed Patent Rights and Licensed Know-How make and have made, to use and have used, to offer to sell, to sell and have sold, and import Licensed Compounds and Licensed Products in the Field.

2.2                               Sublicensing

2.2.1                               Granting

Verastem shall have the right to grant to its Affiliates and to Third Parties sublicenses under the license granted in Section 2.1.  Each such sublicense shall be in writing and shall be consistent with the applicable terms and conditions of this Agreement and sufficient to enable Verastem to meet its diligence and reporting obligations hereunder.  Verastem shall at all times be and remain responsible for its Affiliates’ and Sublicensees’ performance and compliance with the terms and conditions of this Agreement applicable to Affiliates and Sublicensees,  including without limitation payment of all amounts that may become due hereunder as a result of Sublicensee’s activities.  Poniard agrees that Verastem’s obligations under this Agreement may be satisfied through the performance of Verastem’s Affiliates and Sublicensees.  Verastem shall, prior to granting any further sublicense of the Licensed Patent Rights (as defined in the Scripps Agreement) licensed from Scripps, and any Sublicensee shall, prior to granting any further sublicense of the Licensed Patent Rights (as defined in the Scripps Agreement) licensed from Scripps, provide Scripps with a copy of the proposed sublicense agreement, which may be in draft form and which may have financial provisions redacted, for Scripps to review solely for compliance with the provisions of the Scripps Agreement applicable to sublicenses of the Licensed Patent Rights (as defined in the Scripps Agreement) licensed from Scripps, provided however, that any such sublicense shall be subject to the provisions contained in the Scripps Agreement that are applicable to sublicenses (including without limitation the provisions regarding governmental interest, reservation of rights, development efforts, reporting, audit rights, indemnity, warranty disclaimer, limitation of liability, confidentiality, and rights upon expiration or termination but excluding the payment of a license fee).  Such drafts shall be provided to Scripps at least [**] business days prior to the execution of such further sublicenses.  If, within such [**] business day review period, Scripps notifies Verastem or such Sublicensee of provisions of the sublicense that do not comply with the requirements of the Scripps Agreement applicable to sublicenses, Scripps and Verastem (or the applicable Sublicensee granting the further sublicense) shall promptly discuss such concerns and Verastem (or the applicable Sublicensee granting the further sublicense) shall, before entering into the proposed sublicense, negotiate such changes to the proposed sublicense as are reasonably necessary to bring the proposed sublicense into compliance with the requirements of the Scripps Agreement.  In the event of a conflict between the terms of the Scripps Agreement applicable to a sublicense and any sublicense,

9

such terms of the Scripps Agreement shall prevail over the conflicting terms of the sublicense.  Verastem shall forward to Poniard and to Scripps a copy of any all fully executed sublicense agreements within [**] days of execution.

2.2.2                               Survival of Sublicenses

Any sublicense shall, at the election of the applicable Sublicensee, survive termination of this Agreement, in accordance with the provisions of this Section 2.2.2.  Upon termination of this Agreement, and at the written request of a Sublicensee, Poniard will grant to each Sublicensee not then in default of its obligations under its sublicense agreement, an option to obtain directly from Poniard a license agreement on the terms set forth below, which option shall be exercisable by each Sublicensee during the [**] day period commencing on the later of the date of termination of this Agreement or when Sublicensee learns of such termination.  In the event a Sublicensee elects to exercise this option and provides its written notice thereof within the [**] day period, as a condition precedent to Poniard’s obligation to grant the direct license to that Sublicensee, such Sublicensee must pay to Poniard all past due royalties, non-royalty revenue, patent costs and all other monies owed by Verastem to Poniard under this Agreement relating to the license rights hereunder that are sublicensed to Sublicensee. Upon Poniard’s receipt of all such outstanding monies, Poniard shall enter into a license agreement (a “New License Agreement”) directly with the requesting Sublicensee and the license granted in each New License Agreement shall be retroactive to the date of termination of this Agreement.  Each New License Agreement shall be subject to the same non-financial terms and conditions as those in this Agreement; provided, however, that each New License Agreement shall contain substantially the same terms and conditions regarding sublicense scope, sublicense territory, duration of sublicense grant, and diligence obligations as the sublicense agreement between such Sublicensee and Verastem.  In addition, (a) each Sublicensee shall agree in the New License Agreement to terms providing that in no event shall Poniard be liable to Sublicensee for any actual or alleged breach of such sublicense agreement by Verastem; (b) Poniard shall not have any obligations to such Sublicensee other than Poniard’s obligations to Verastem as set forth herein; and (c) in no event shall Poniard be obliged to accept provisions in the New License Agreement (i) unless such provisions correspond to rights granted by Verastem to Sublicensee in conformance with this Agreement and such provisions are not in conflict with the rights, duties and obligations accruing to the Verastem under this Agreement; or (ii) where such provisions are inconsistent with the legal obligations under any other sublicense agreement granted by Verastem, or by applicable federal, state or local statute or regulation.  The financial consideration to Poniard under the New License Agreement shall be as follows:  each such Sublicensee shall be required to make any monetary payment(s) to Poniard that, had this Agreement not been terminated, Verastem would have been required to make to Poniard under this Agreement based on the rights sublicensed to Sublicensee.  Verastem must include or specifically reference this Section 2.2.2 in each of its sublicense agreements in order for such Sublicensee to have the option described above.

2.3                               No Other License

This Agreement confers no license or rights by implication, estoppel, or otherwise under any patent applications or patents of Poniard other than Licensed Patent Rights regardless of whether such patents are dominant or subordinate to Licensed Patent Rights.

10

2.4                               Government Interest

Verastem and Poniard acknowledge that Scripps has received, and expects to continue to receive, funding from the United States Government in support of Scripps’ research activities.  Verastem and Poniard acknowledge and agree that their respective rights and obligations pursuant to this Agreement shall be subject to the rights of the United States Government, existing and as amended, which may arise or result from Scripps’ receipt of research support from the United States Government, including but not limited to, 37 C.F.R. 401, the NIH Grants Policy Statement and the NIH Guidelines for Obtaining and Disseminating Biomedical Research Resources.

2.5                               Reservation of Rights

With respect to the Licensed Patent Rights licensed to Poniard pursuant to the Scripps Agreement (the “Scripps Patent Rights”), Verastem acknowledges that Scripps has retained rights under the Scripps Agreement for itself and the United States government, including the right of Scripps to grant nonexclusive licenses (without the right to sublicense) to nonprofit or academic institutions to use for any noncommercial research or educational purposes any Scripps Patent Rights.  Upon Verastem’s request, Poniard shall provide Verastem, but not more frequently than quarterly, a list of any such nonexclusive licenses, including the name of the nonprofit or academic institution and the scope of the license, which shall be deemed to be confidential information of Poniard under the terms of this Agreement.

(b) [**] percent ([**]%) of aggregate worldwide Net Sales greater than $[**], but less than $[**] of Licensed Products made by Verastem, its Affiliates or its Sublicensees in the Calendar Year; or

(c) [**] percent ([**]%) of aggregate worldwide Net Sales greater than $[**] of Licensed Products made by Verastem, its Affiliates or its Sublicensees in the Calendar Year;

(iii) [**] percent ([**]%) of aggregate worldwide Net Sales greater than $[**] of Licensed Products made by Verastem, its Affiliates or its Sublicensees in the Calendar Year.

14

4.4.2                               Multiple Royalties

No multiple royalties shall be due because any Licensed Product is Covered by more than one of the Licensed Patent Rights or patent claims therein.  With respect to a particular Net Sales of a Licensed Product, Verastem shall pay only one royalty to Poniard, as applicable, pursuant to Section 4.4.

4.4.3                               Third Party Payments

Poniard shall be responsible for one hundred percent (100%) of all amounts payable to any Third Party under any agreement or arrangement to which Poniard is a party as of the Effective Date and that are applicable to the Licensed Compound, Licensed Product, Licensed Know-How and/or Licensed Patent Rights, including amounts payable to Scripps under the Scripps Agreement.  If Poniard enters into any agreement or arrangement with a Third Party after the Effective Date under which Poniard obtains Control of Know-How,  Patent Rights or other intellectual property rights that are necessary to research, develop, use, make, have made, market, offer to sell, sell, have sold, distribute, import or otherwise exploit the Licensed Compound and/or Licensed Product, Verastem shall have the right to have such Know-How,  Patent Rights or other intellectual property rights included in the Licensed Know-How and/or Licensed Patent Rights, in which case Verastem shall be responsible for any amounts payable to the Third Party on account of such sublicense to Verastem hereunder, provided that such amounts shall be deemed to be amounts that Verastem pays to a Third Party to license or acquire technology from a Third Party for purposes of the royalty reduction provisions of the paragraph below.  If Verastem does not elect to have such Know-How,  Patent Rights or other intellectual property rights included in the Licensed Know-How and/or Licensed Patent Rights (and to pay such amounts payable to the Third Party) as set forth in the immediately preceding sentence, such Know-How,  Patent Rights or other intellectual property rights shall be deemed to not be Licensed Know-How or Licensed Patent Rights.

If Verastem, its Affiliate or its Sublicensee licenses or acquires technology from a Third Party in order to develop or commercialize a Licensed Product, and Verastem, its Affiliate or its Sublicensee is required to pay such Third-Party(ies) license fees, milestone payments, royalties or other amounts, then Verastem may deduct up to fifty percent (50%) of the amount paid to such Third Parties from the payments owing to Poniard for such Licensed Product.  In no event will a deduction, or deductions, under this Section 4.4.3 reduce any payment made by Verastem to Poniard hereunder to less than fifty percent (50%) of the otherwise applicable payment amount.  If, but for the preceding sentence, a deduction under this Section 4.4.3 would have reduced a payment made by Verastem to Poniard hereunder to less than fifty percent (50%) of the otherwise applicable payment amount, the amount of such deduction that was not deducted due to such limitation shall be carried forward for deduction against subsequent payments hereunder.  Notwithstanding the foregoing, if a deduction under this Section 4.4.3 would reduce a royalty payment made by Verastem to Poniard hereunder with respect to Net Sales by Verastem and its Affiliates and Sublicensees to less than the royalty payment amount that Poniard is required to pay Scripps pursuant to the Scripps Agreement with respect to Net Sales by Verastem and its Affiliates and Sublicensees, Verastem shall pay to Poniard an additional royalty payment amount so that the total royalty payment amount that Verastem pays to Poniard equals the royalty payment amount that Poniard is required to pay Scripps pursuant to the Scripps Agreement with respect to Net Sales by Verastem and its Affiliates and Sublicensees.

15

4.4.4                               Royalty Term

(c)           Notwithstanding the foregoing, in the event that (i) the Royalty Term with respect to a Licensed Product and a country terminates hereunder and (ii) Poniard continues to have royalty payment obligations under Section 3.3 of the Scripps Agreement (as such amount may be adjusted in accordance with Section 3.6 of the Scripps Agreement) with respect to Net Sales of Licensed Products by Verastem and its Affiliates and Sublicensees in such country, Verastem shall pay to Poniard the royalty amount due to Scripps pursuant to Section 3.3 of the Scripps Agreement (as such amount may be adjusted in accordance with Section 3.6 of the Scripps Agreement) with respect to such Net Sales of Licensed Products in such country.

4.4.5          Royalty Increase for Licensed Products

Notwithstanding Section 4.4.1, in the event Verastem Challenges an issued patent or patent application included in the Licensed Patent Rights, the royalty rate specified in Section 4.4.1 shall be increased by [**] percent ([**]%) during the pendency of the Challenge (and by [**] percent ([**]%) in the event Verastem’s Challenge is unsuccessful) with respect to the Net Sales of  the Licensed Products that would, in the absence of the license granted by this Agreement, infringe a Valid Claim of the Challenged patent or patent application in the country of sale, such increase to occur with respect to of the Calendar Quarter commencing immediately after the date Verastem first institutes such Challenge.

In the event Verastem institutes a Challenge, Verastem shall have no right to recoup, recover, set off or otherwise get reimbursement of any royalties, milestone payments, patent costs or other monies paid hereunder during the period of such Challenge. Verastem hereby voluntarily and irrevocably waives any right to seek return of such royalties, milestone payments, patent costs or other monies in the event Verastem directly or indirectly institutes any Challenge.

4.6                               Royalty Payments

Verastem shall pay to Poniard with each Royalty Report the amount of royalty due with respect to such quarter.  If multiple technologies are covered by the license granted hereunder, Verastem shall specify which Licensed Patent Rights are utilized for each Licensed Product included in the Royalty Report.  All payments due hereunder shall be deemed received when funds are credited to Poniard’s bank account and shall be payable by check or wire transfer in United States Dollars.

4.7                               Foreign Sales

The remittance of royalties payable on sales outside the United States shall be payable to Poniard in United States Dollar equivalents at the official rate of exchange of the currency of the country from which the royalties are payable, as quoted in The Wall Street Journal, East Coast edition for the last business day of the Calendar Quarter in which the royalties are payable.  If the transfer of or the conversion into the United States Dollar equivalents of any such remittance in any such instance is not lawful or possible, the payment of such part of the royalties as is necessary shall be made by the deposit thereof, in the currency of the country where the sale was made on which the royalty was based to the credit and account of Poniard or its nominee in any commercial bank or trust company of Poniard’s choice located in that country, prompt written notice of which shall be given by Verastem to Poniard.

4.9                               Late Payments

Late payments of any and all payments due hereunder shall be subject to a charge of one and one-half percent (1-1/2%) per month, or two hundred and fifty dollars ($250) whichever is greater.

4.10                        Record Keeping

Verastem shall keep, and shall require its Affiliates and Sublicensees to keep, accurate records (together with supporting documentation) of Licensed Products made, used or sold under this Agreement, appropriate to determine the amount of royalties, milestone payments and other monies due to Poniard hereunder.  Such records shall be retained for at least [**] years following the end of the reporting period to which such records relate.  They shall be available during normal business hours for examination and copying by an independent certified public accountant selected by Poniard (and reasonably acceptable to Verastem) and under an obligation of confidentiality to Verastem, for the purpose of verifying Verastem’s reports and payments hereunder.  In conducting examinations pursuant to this Section, Poniard’s accountant shall have access to all records which are reasonably relevant to the calculation of payments to Poniard under Article 4.

17

audit shall be made available to both Parties.  Poniard’s accountant shall not disclose to Poniard any information other than information relating to the accuracy of reports and payments made hereunder.

Such examination by Poniard’s accountant shall be at Poniard’s expense.  If there has been an underreporting or underpayment in excess of five percent (5%) for any calendar year then Verastem shall pay the reasonable and documented cost of such examination as well as any additional sum that would have been payable to Poniard had the Verastem reported correctly, plus interest in accordance with Section 4.9.  All payments due hereunder shall be made within [**] days of receipt of a written invoice from Poniard.

11.8                        Entire Agreement; Modification

This Agreement and all of the attached Exhibits, set forth the entire agreement and understanding between the Parties as to the subject matter hereof, and supersede all prior or contemporaneous agreements or understandings, whether oral or written.  There shall be no amendments or modifications to this Agreement, except by a written document which is signed by both Parties.

11.11                 Severability

Should any one or more of the provisions of this Agreement be held invalid or unenforceable by a court of competent jurisdiction, it shall be considered severed from this Agreement and shall not serve to invalidate the remaining provisions thereof.  The Parties shall make a good faith effort to replace any invalid or unenforceable provision with a valid and enforceable one such that the objectives contemplated by them when entering this Agreement may be realized.

11.12                 No Waiver

Any delay in enforcing a Party’s rights under this Agreement or any waiver as to a particular default or other matter shall not constitute a waiver of such Party’s rights to the future enforcement of its rights under this Agreement, excepting only as to an express written and signed waiver as to a particular matter for a particular period of time.

11.13                 Attorneys’ Fees

In the event of a dispute between the Parties hereto or in the event of any default hereunder, the Party prevailing in the resolution of any such dispute or default shall be entitled to recover its reasonable attorneys’ fees and other costs incurred in connection with resolving such dispute or default.  Notwithstanding anything to the contrary herein, the Parties agree that this Section 11.13 shall not apply, and attorneys’ fees shall not be awarded to either Party, with respect to any Challenge or any action wherein Verastem alleges that it is not required to comply with or perform some or all of the provisions of this Agreement based upon a good faith claim that any of the Licensed Patent Rights are invalid or unenforceable.  Each Party acknowledges and agrees that this Agreement has been submitted to the scrutiny of the Party and its own counsel, from whom the Party has sought advice and received representation in the negotiation and execution of this Agreement.  This Agreement shall be given a fair and reasonable interpretation in accordance with the words hereof, without consideration or weight being given to it having been drafted by, or on behalf of, one of the Parties or its counsel.

(1)                                  If the Common Stock is listed on a national securities exchange or another nationally recognized trading system as of the Exercise Date, the Fair Market Value per share of Common Stock shall be deemed to be the average of the high and low reported sale prices per share of Common Stock thereon on the trading day immediately preceding the Exercise Date (provided that if no such price is reported on such day, the Fair Market Value per share of Common Stock shall be determined pursuant to clause (2)).

(2)                                  If the Common Stock is not listed on a national securities exchange as of the Exercise Date, the Fair Market Value per share of Common Stock shall be deemed to be the amount most recently determined by the Board of Directors of the Company (the “Board”) to represent the fair market value per share of the Common Stock (including without limitation a determination for purposes of granting Common Stock options or issuing Common Stock under any plan, agreement or arrangement with employees of the Company); and, upon request of the Registered Holder, the Board (or a representative thereof) shall, as promptly as reasonably practicable but in any event not later than 10 days after such request, notify the Registered Holder of the Fair Market Value per share of Common Stock and furnish the Registered Holder with reasonable documentation of the Board’s determination of such Fair Market Value.  Notwithstanding the foregoing, if the Board has not made such a determination within the three-month period prior to the Exercise Date, then (A) the Board shall make, and shall provide or cause to be provided to the Registered Holder notice of, a determination of the Fair Market Value per share of the Common Stock within 15 days of a request by the Registered Holder that it do so, and (B) the exercise of this Warrant pursuant to this subsection 1(b) shall be delayed until such determination is made and notice thereof is provided to the Registered Holder.

2

(c)                                  Exercise Date.  Each exercise of this Warrant shall be deemed to have been effected immediately prior to the close of business on the day on which this Warrant shall have been surrendered to the Company as provided in subsection 1(a) or 1(b) above (the “Exercise Date”).  At such time, the person or persons in whose name or names any certificates for Warrant Shares shall be issuable upon such exercise as provided in subsection 1(d) below shall be deemed to have become the holder or holders of record of the Warrant Shares represented by such certificates.

(d)                                 Issuance of Certificates.  As soon as practicable after the exercise of this Warrant in whole or in part, and in any event within 10 days thereafter, the Company, at its expense, will cause to be issued in the name of, and delivered to, the Registered Holder, or as the Registered Holder (upon payment by the Registered Holder of any applicable transfer taxes) may direct:

(i)                                     a certificate or certificates for the number of full Warrant Shares to which the Registered Holder shall be entitled upon such exercise plus, in lieu of any fractional share to which the Registered Holder would otherwise be entitled, cash in an amount determined pursuant to Section 3 hereof; and

(ii)                                  in case such exercise is in part only, a new warrant or warrants (dated the date hereof) of like tenor, calling in the aggregate on the face or faces thereof for the number of Warrant Shares equal (without giving effect to any adjustment therein) to the number of such shares called for on the face of this Warrant minus the number of Warrant Shares for which this Warrant was so exercised (which, in the case of an exercise pursuant to subsection 1(b), shall include both the number of Warrant Shares issued to the Registered Holder pursuant to such partial exercise and the number of Warrant Shares subject to the portion of the Warrant being cancelled in payment of the Purchase Price).

2.                                       Adjustments.

(a)                                  Adjustment for Stock Splits and Combinations.  If the Company shall at any time or from time to time after the date on which this Warrant was first issued (or, if this Warrant was issued upon partial exercise of, or in replacement of, another warrant of like tenor, then the date on which such original warrant was first issued) (either such date being referred to as the “Original Issue Date”) effect a subdivision of the outstanding Common Stock, the Purchase Price then in effect immediately before that subdivision shall be proportionately decreased.  If the Company shall at any time or from time to time after the Original Issue Date combine the outstanding shares of Common Stock, the Purchase Price then in effect immediately before the combination shall be proportionately increased.  Any adjustment under this paragraph shall become effective at the close of business on the date the subdivision or combination becomes effective.

(b)                                 Adjustment for Certain Dividends and Distributions.  In the event the Company at any time, or from time to time after the Original Issue Date shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in additional shares of Common Stock, then and in each such event the Purchase Price then in effect immediately before such event shall be decreased as

3

of the time of such issuance or, in the event such a record date shall have been fixed, as of the close of business on such record date, by multiplying the Purchase Price then in effect by a fraction:

(1)                                  the numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date, and

(2)                                  the denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of shares of Common Stock issuable in payment of such dividend or distribution;

provided, however, that if such record date shall have been fixed and such dividend is not fully paid or if such distribution is not fully made on the date fixed therefor, the Purchase Price shall be recomputed accordingly as of the close of business on such record date and thereafter the Purchase Price shall be adjusted pursuant to this paragraph as of the time of actual payment of such dividends or distributions.

(c)                                  Adjustment in Number of Warrant Shares.  When any adjustment is required to be made in the Purchase Price pursuant to subsections 2(a) or 2(b), the number of Warrant Shares purchasable upon the exercise of this Warrant shall be changed to the number determined by dividing (i) an amount equal to the number of shares issuable upon the exercise of this Warrant immediately prior to such adjustment, multiplied by the Purchase Price in effect immediately prior to such adjustment, by (ii) the Purchase Price in effect immediately after such adjustment.

(d)                                             Adjustments for Other Dividends and Distributions.  In the event the Company at any time or from time to time after the Original Issue Date shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in securities of the Company (other than shares of Common Stock) or in cash or other property (other than regular cash dividends paid out of earnings or earned surplus, determined in accordance with generally accepted accounting principles), then and in each such event provision shall be made so that the Registered Holder shall receive upon exercise hereof, in addition to the number of shares of Common Stock issuable hereunder, the kind and amount of securities of the Company, cash or other property which the Registered Holder would have been entitled to receive had this Warrant been exercised on the date of such event and had the Registered Holder thereafter, during the period from the date of such event to and including the Exercise Date, retained any such securities receivable during such period, giving application to all adjustments called for during such period under this Section 2 with respect to the rights of the Registered Holder.

(e)                                  Adjustment for Reorganization.  If there shall occur any reorganization, recapitalization, reclassification, consolidation or merger involving the Company in which the Common Stock is converted into or exchanged for securities, cash or other property (other than a transaction covered by subsections 2(a), 2(b) or 2(d)) (collectively, a “Reorganization”), then, following such Reorganization, the Registered Holder shall receive upon exercise hereof the kind

4

and amount of securities, cash or other property which the Registered Holder would have been entitled to receive pursuant to such Reorganization if such exercise had taken place immediately prior to such Reorganization.  In any such case, appropriate adjustment (as determined in good faith by the Board) shall be made in the application of the provisions set forth herein with respect to the rights and interests thereafter of the Registered Holder, to the end that the provisions set forth in this Section 2 (including provisions with respect to changes in and other adjustments of the Purchase Price) shall thereafter be applicable, as nearly as reasonably may be, in relation to any securities, cash or other property thereafter deliverable upon the exercise of this Warrant.

(f)                                    Certificate as to Adjustments.  Upon the occurrence of each adjustment or readjustment of the Purchase Price pursuant to this Section 2, the Company at its expense shall, as promptly as reasonably practicable but in any event not later than 10 days thereafter, compute such adjustment or readjustment in accordance with the terms hereof and furnish to the Registered Holder a certificate setting forth such adjustment or readjustment (including the kind and amount of securities, cash or other property for which this Warrant shall be exercisable and the Purchase Price) and showing in detail the facts upon which such adjustment or readjustment is based.  The Company shall, as promptly as reasonably practicable after the written request at any time of the Registered Holder (but in any event not later than 10 days thereafter), furnish or cause to be furnished to the Registered Holder a certificate setting forth (i) the Purchase Price then in effect and (ii) the number of shares of Common Stock and the amount, if any, of other securities, cash or property which then would be received upon the exercise of this Warrant.

3.                                       Fractional Shares.  The Company shall not be required upon the exercise of this Warrant to issue any fractional shares, but shall pay the value thereof to the Registered Holder in cash on the basis of the Fair Market Value per share of Common Stock, as determined pursuant to subsection 1(b)(ii) above.

4.                                       Investment Representations.  The initial Registered Holder represents and warrants to the Company as follows:

(a)                                  Investment.  It is acquiring the Warrant, and (if and when it exercises this Warrant) it will acquire the Warrant Shares, for its own account for investment and not with a view to, or for sale in connection with, any distribution thereof, nor with any present intention of distributing or selling the same; and the Registered Holder has no present or contemplated agreement, undertaking, arrangement, obligation, indebtedness or commitment providing for the disposition thereof.

(b)                                 Accredited Investor.  The Registered Holder is an “accredited investor” as defined in Rule 501(a) under the Securities Act of 1933, as amended (the “Act”).

(c)                                  Experience.  The Registered Holder has made such inquiry concerning the Company and its business and personnel as it has deemed appropriate; and the Registered Holder has sufficient knowledge and experience in finance and business that it is capable of evaluating the risks and merits of its investment in the Company.

5.                                       Transfers, etc.

(a)                                  This Warrant and the Warrant Shares shall not be sold or transferred unless either (i) they first shall have been registered under the Act, or (ii) the Company first shall have been furnished with an opinion of legal counsel, reasonably satisfactory to the Company, to the effect that such sale or transfer is exempt from the registration requirements of the Act.  Notwithstanding the foregoing, no registration or opinion of counsel shall be required for (i) a transfer by a Registered Holder which is an entity to a wholly owned subsidiary of such entity, a transfer by a Registered Holder which is a partnership to a partner of such partnership or a retired partner of such partnership or to the estate of any such partner or retired partner, or a transfer by a Registered Holder which is a limited liability company to a member of such limited liability company or a retired member or to the estate of any such member or retired member, provided that the transferee in each case agrees in writing to be subject to the terms of this Section 5, or (ii) a transfer made in accordance with Rule 144 under the Act.

(b)                                 Each certificate representing Warrant Shares shall bear a legend substantially in the following form:

“The securities represented by this certificate have not been registered under the Securities Act of 1933, as amended, and may not be offered, sold or otherwise transferred, pledged or hypothecated unless and until such securities are registered under such Act or an opinion of counsel satisfactory to the Company is obtained to the effect that such registration is not required.”

The foregoing legend shall be removed from the certificates representing any Warrant Shares, at the request of the holder thereof, at such time as (i) a period of at least one year, as determined in accordance with paragraph (d) of Rule 144 under the Act, has elapsed since the later of the date the Warrant Shares were acquired from the Company or an affiliate of the Company, and (ii) the Warrant Shares become eligible for resale pursuant to Rule 144(b)(1)(i) under the Act.

(c)                                  The Company will maintain a register containing the name and address of the Registered Holder of this Warrant.  The Registered Holder may change its address as shown on the warrant register by written notice to the Company requesting such change.

(d)                                 Subject to the provisions of Section 5 hereof, this Warrant and all rights hereunder are transferable, in whole or in part, upon surrender of this Warrant with a properly executed assignment (in the form of Exhibit II hereto) at the principal office of the Company (or, if another office or agency has been designated by the Company for such purpose, then at such other office or agency).

6.                                       Notices of Record Date, etc.  In the event:

(a)                                  the Company shall take a record of the holders of its Common Stock (or other stock or securities at the time deliverable upon the exercise of this Warrant) for the purpose of entitling or enabling them to receive any dividend or other distribution, or to receive any right to subscribe for or purchase any shares of stock of any class or any other securities, or to receive any other right; or

6

(b)                                 of any capital reorganization of the Company, any reclassification of the Common Stock of the Company, any consolidation or merger of the Company with or into another corporation, or any transfer of all or substantially all of the assets of the Company; or

(c)                                  of the voluntary or involuntary dissolution, liquidation or winding-up of the Company, then, and in each such case, the Company will send or cause to be sent to the Registered Holder a notice specifying, as the case may be, (i) the record date for such dividend, distribution or right, and the amount and character of such dividend, distribution or right, or (ii) the effective date on which such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation or winding-up is to take place, and the time, if any is to be fixed, as of which the holders of record of Common Stock (or such other stock or securities at the time deliverable upon the exercise of this Warrant) shall be entitled to exchange their shares of Common Stock (or such other stock or securities) for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation or winding-up.  Such notice shall be sent at least 5 days prior to the record date or effective date for the event specified in such notice.

7.                                       Reservation of Stock.  The Company will at all times reserve and keep available, solely for issuance and delivery upon the exercise of this Warrant, such number of Warrant Shares and other securities, cash and/or property, as from time to time shall be issuable upon the exercise of this Warrant.

8.                                       Exchange or Replacement of Warrants.

(a)                                  Upon the surrender by the Registered Holder, properly endorsed, to the Company at the principal office of the Company, the Company will, subject to the provisions of Section 5 hereof, issue and deliver to or upon the order of the Registered Holder, at the Company’s expense, a new Warrant or Warrants of like tenor, in the name of the Registered Holder or as the Registered Holder (upon payment by the Registered Holder of any applicable transfer taxes) may direct, calling in the aggregate on the face or faces thereof for the number of shares of Common Stock (or other securities, cash and/or property) then issuable upon exercise of this Warrant.

(b)                                 Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and (in the case of loss, theft or destruction) upon delivery of an indemnity agreement (with surety if reasonably required) in an amount reasonably satisfactory to the Company, or (in the case of mutilation) upon surrender and cancellation of this Warrant, the Company will issue, in lieu thereof, a new Warrant of like tenor.

9.                                       Notices.  All notices and other communications from the Company to the Registered Holder in connection herewith shall be mailed by certified or registered mail, postage prepaid, or sent via a reputable nationwide overnight courier service guaranteeing next business day delivery, to the address last furnished to the Company in writing by the Registered Holder.  All notices and other communications from the Registered Holder to the Company in connection herewith shall be mailed by certified or registered mail, postage prepaid, or sent via a reputable

7

nationwide overnight courier service guaranteeing next business day delivery, to the Company at its principal office set forth below.  If the Company should at any time change the location of its principal office to a place other than as set forth below, it shall give prompt written notice to the Registered Holder and thereafter all references in this Warrant to the location of its principal office at the particular time shall be as so specified in such notice. All such notices and communications shall be deemed delivered (i) two business days after being sent by certified or registered mail, return receipt requested, postage prepaid, or (ii) one business day after being sent via a reputable nationwide overnight courier service guaranteeing next business day delivery.

10.                                 No Rights as Stockholder.  Until the exercise of this Warrant, the Registered Holder shall not have or exercise any rights by virtue hereof as a stockholder of the Company.  Notwithstanding the foregoing, in the event (i) the Company effects a split of the Common Stock by means of a stock dividend and the Purchase Price of and the number of Warrant Shares are adjusted as of the date of the distribution of the dividend (rather than as of the record date for such dividend), and (ii) the Registered Holder exercises this Warrant between the record date and the distribution date for such stock dividend, the Registered Holder shall be entitled to receive, on the distribution date, the stock dividend with respect to the shares of Common Stock acquired upon such exercise, notwithstanding the fact that such shares were not outstanding as of the close of business on the record date for such stock dividend.

11.                                 Amendment or Waiver.  Any term of this Warrant may be amended or waived only by an instrument in writing signed by the party against which enforcement of the change or waiver is sought. No waivers of any term, condition or provision of this Warrant, in any one or more instances, shall be deemed to be, or construed as, a further or continuing waiver of any such term, condition or provision.

12.                                 Section Headings.  The section headings in this Warrant are for the convenience of the parties and in no way alter, modify, amend, limit or restrict the contractual obligations of the parties.

13.                                 Governing Law.  This Warrant will be governed by and construed in accordance with the internal laws of the State of New York (without reference to the conflicts of law provisions that would cause the application of the laws of any other jurisdiction).
