This Agreement (the “Agreement”), dated as of November 18, 2007, is entered into by and between Syntroleum Corporation, a Delaware corporation (together with its successors, the “Company”), and Fletcher International, Ltd., a company domiciled in Bermuda (together with its successors, the “Purchaser”).

The parties hereto agree as follows:

1. Purchase and Sale. In consideration of and upon the basis of the representations, warranties and agreements and subject to the terms and conditions set forth in this Agreement:

(a) Subject to satisfaction or, if applicable, waiver of the relevant conditions set forth in Sections 13 and 14 hereof and subject to the provisions of Section 7(a) hereof, Purchaser agrees to purchase (the “Initial Investment”) from the Company, and the Company agrees to issue and sell to Purchaser on the Initial Investment Closing Date (as defined below), in accordance with Section 3, that number of shares of the Company’s common stock, par value one cent ($0.01) per share (together with the associated common stock purchase rights under the Second Amended and Restated Rights Agreement dated as of October 28, 2004, the “Common Stock”) that may be purchased with Three Million Dollars ($3,000,000) at a price per share equal to the Initial Investment Price. Purchaser shall have the rights with respect to such shares of Common Stock specified in this Agreement and in the Warrant.

(b) Subject to satisfaction or, if applicable, waiver of the relevant conditions set forth in Sections 13 and 14 hereof and subject to the provisions of Section 7(a) hereof, Purchaser agrees to purchase from the Company, and the Company agrees to issue and sell to Purchaser (each a “Later Investment”), from time to time, in whole or in part, that number of shares of Common Stock that may be purchased with an aggregate purchase price of Nine Million Dollars ($9,000,000) (the “Aggregate Later Investment Commitment”) at a price per share equal to the Later Investment Price on the date of the relevant Later Investment Notice (as defined below). To effect any Later Investment, Purchaser shall deliver a written notice substantially in the form attached hereto as Annex A (a “Later Investment Notice”) to the Company from time to time during that period commencing on and including May 18, 2008 and ending no later than November 18, 2009, subject to extension as set forth herein (the “Later Investment Period”). Subject to satisfaction or, if applicable, waiver of the relevant conditions set forth in Sections 13 and 14 hereof, the closing of each Later Investment (each, a “Later Investment Closing”) shall take place at 9:30 a.m. New York City time on the date that is three (3) Business Days following and excluding the date of delivery of the Later Investment Notice or on such other date as Purchaser and the Company shall mutually agree (each such date and time being referred to herein as a “Later Investment Closing Date”). Subject to the provisions of Sections 1(d) and 11(c) hereof, prior to the expiration of the Later Investment Period, Purchaser shall have consummated Later Investments in an aggregate amount equal to the Aggregate Later Investment Commitment, and each Later Investment shall be in an amount of not less than two million dollars ($2,000,000), unless that portion of the Aggregate Later Investment Commitment then remaining to be purchased by Purchaser is less than two million dollars ($2,000,000), in which instance, such Later Investment shall be for such lesser amount. For the avoidance of doubt, subject to the provisions of Sections 1(d) and 11(c) hereof, the Aggregate Later Investment Commitment shall be reduced on a dollar-for-dollar basis by the Investment Amount paid (or in the case of Cashless Exercise (as defined below), deemed paid) on each Later Investment.

(c) The Later Investment Period shall be extended: by two (2) Business Days for each Business Day:

(i) that the Registration Statement (as defined below) is not effective and available for the issuance of all Common Stock issuable under this Agreement; or

(ii) occurring during the period (x) commencing on the earlier of the day on which the Company restates or announces its intention to restate any portion of the Company Financial Statements, and (b) ending on the date on which the Company files quarterly or annual financial statements that constitute a Restatement on a Form 10-K, Form 10-Q, Form 8-K or any other filing with the SEC (and if the Company makes multiple filings of a Restatement with the SEC, the last of such dates) (the “Restatement Filing Date”).

To the extent that the Company (i) restates or announces its intention to restate any portion of the Company Financial Statements (as defined below) or (ii) fails to maintain the effectiveness and availability of the Registration Statement for the issuance of all Common Stock issuable under this Agreement, in either case, within sixty-five (65) Business Days of the expiration of the Later Investment Period, the Later Investment Period shall be extended to a date that is at least sixty-five (65) Business Days after the later of the Restatement Filing Date or the remediation of the failure described in clause (ii) of this Section 1(c).

(d) If the conditions set forth in Section 13 hereof are not satisfied or waived on or prior to 9:30 a.m. New York City time on the relevant Later Investment Closing Date or if the Company fails to perform its obligations on any Later Investment Closing Date (including delivery of all shares of Common Stock issuable on such date) for any reason other than the Purchaser’s failure to satisfy the conditions required by Section 14 hereof, then in addition to all remedies available to the Purchaser at law or in equity, the Purchaser may, at its sole option, and at any time, withdraw the Later Investment Notice by written notice to the Company regardless of whether such condition has been satisfied or waived as of the withdrawal date and, after such withdrawal, shall have no further obligations with respect to such Later Investment Notice. Upon any such withdrawal, the Aggregate Later Investment Commitment shall be reduced on a dollar-per-dollar basis by the Investment Amount (as defined below) set forth in the withdrawn Later Investment Notice (each such reduction, a “Withdrawal Reduction”) and the Purchaser shall no longer have an obligation to consummate a Later Investment with respect to such Withdrawal Reduction, but rather, at any time during the Later Investment Period, Purchaser may deliver a Later Investment Notice to effect a Later Investment with respect to any part or all of such Withdrawal Reduction in the Purchaser’s sole discretion at a price per share equal to the Later Investment Price computed as of the date of such subsequently delivered Later Investment Notice.

(e) In addition, the Company shall issue to Purchaser on the Initial Investment Closing Date a warrant in the form attached hereto as Annex B (the “Warrant”) evidencing rights to purchase from the Company, subject to the terms and conditions set forth in the Warrant, up to a number of shares of Common Stock as set forth therein.

The Company and its subsidiaries are duly qualified and are authorized to do business and are in good standing as foreign corporations in all jurisdictions in which the nature of their activities and of their properties (both owned and leased) makes such qualification necessary, except for those jurisdictions in which failure to do so would not, individually or in the aggregate, be reasonably expected to have a Material Adverse Effect on (i) the business affairs, assets, results of operations or prospects of the Company or any of its subsidiaries, or (ii) the transactions contemplated by, or the Company’s ability to perform under, this Agreement or the Warrant.

(k) Since January 1, 2005, none of the Company’s filings with the United States Securities and Exchange Commission (the “SEC”) under the Securities Act or under Section 13 or 15(d) of the Exchange Act, including the financial statements, schedules, exhibits and results of the Company’s operations and cash flow contained therein (each an “SEC Filing”), contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements, in the light of the circumstances under which they were made, not misleading. Since January 1, 2005, there has not been any pending or, to the best knowledge of the Company, threatened action, suit, proceeding or investigation before any court, governmental agency or body, or arbitrator having jurisdiction over the Company or any of its subsidiaries that will or is reasonably likely to result in a Material Adverse Effect except as disclosed in the Company’s SEC Filings on or before the date immediately prior to and excluding the date hereof.

The Company reasonably believes it has sufficient capital or access to capital with which to conduct its business as presently conducted and as proposed to be conducted. The Company has not incurred debt, and does not intend to incur debt, beyond its ability to pay such debt as it matures. For purposes of this paragraph, “debt” means any liability on a claim, and “claim” means (x) a right to payment, whether or not such right is reduced to judgment, liquidated, unliquidated, fixed, contingent, matured, unmatured, disputed, undisputed, legal, equitable, secured, or unsecured, or (y) a right to an equitable remedy for breach of performance if such breach gives rise to a payment, whether or not such right to an equitable remedy is reduced to judgment, fixed, contingent, matured, unmatured, disputed, undisputed, secured, or unsecured. With respect to any such contingent liabilities, such liabilities are computed at the amount which, in light of all the facts and circumstances existing at the time, represents the amount which can reasonably be expected to become an actual or matured liability.

(o) Equivalent Value. As of the Closing Date, the consideration that the Company is receiving from Purchaser is substantially equivalent in value to the consideration Purchaser is receiving from the Company pursuant to this Agreement. As of the Closing Date, under the terms of this Agreement, the Company is receiving fair consideration from Purchaser for the agreements, covenants, representations and warranties made by the Company to Purchaser.

(p) No Non-Public Information. Except as set forth on Schedule 5(p), Purchaser has not requested from the Company, and the Company has not furnished to Purchaser, any material non-public information concerning the Company or its subsidiaries.

(q) Restatement Notices. As of the date of each Closing, the Company has provided Purchaser with all Restatement Notices required to be delivered following a Restatement (as defined below).

(r) Application of Takeover Protections. There is no control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision under the Company’s charter documents or the laws of its state of incorporation that is or would become applicable to the Purchaser as a result of the Purchaser and the Company fulfilling their obligations or exercising their rights under this Agreement and the Warrant, including, without limitation, as a result of the Company’s issuance of the Common Stock issuable hereunder and the Purchaser’s ownership of the Common Stock issuable hereunder.

(s) Backdating of Options. The exercise price of each Company option has been no less than the fair market value of a share of Common Stock as determined on the date of grant of such Company option. All grants of Company options were validly issued and properly approved by the Board of Directors of the Company (or a duly authorized committee or subcommittee thereof) in material compliance with all applicable legal requirements and recorded on the Company’s financial statements in accordance with U.S. generally accepted accounting principles, and no such grants involved any “back dating,” “forward dating” or similar practices with respect to the effective date of grant.

(t) Placement Agent’s Fees. The Company shall be responsible for the payment of any placement agent’s fees, financial advisory fees, or brokers’ commissions, in each case payable to third parties retained by the Company, relating to or arising out of the Offering pursuant to this Agreement. The Company shall pay, and hold the Purchaser harmless against, any liability, loss or expense (including, without limitation, reasonable attorney’s fees and out-of-pocket expenses) arising in connection with any such claim for fees arising out of the Offering pursuant to this Agreement.

(w) Regulatory Permits. The Company possesses all certificates, authorizations and permits issued by the appropriate federal, state or foreign regulatory authorities necessary to conduct its business, except where the failure to possess such certificates, authorizations or permits would not have a Material Adverse Effect. The Company is not in violation of any judgment, decree or order or any statute, ordinance, rule or regulation applicable to it, except for violations which would not have a Material Adverse Effect.

(x) Foreign Corrupt Practices. Neither the Company nor any director, officer, agent, employee or other Person acting on behalf of the Company has, in the course of its actions for, or on behalf of, the Company (i) used any corporate funds for any unlawful contribution, gift, entertainment or other unlawful expenses relating to political activity; (ii) made any direct or indirect unlawful payment to any foreign or domestic government official or employee from corporate funds; (iii) violated or is in violation of any provision of the U.S. Foreign Corrupt Practices Act of 1977, as amended; or (iv) made any unlawful bribe, rebate, payoff, influence payment, kickback or other unlawful payment to any foreign or domestic government official or employee.

Thereafter, the Company shall notify Purchaser promptly of any material developments with respect to such transaction, including advance notice at least ten (10) Business Days before the date such transaction is expected to become effective.

(c) In the event that a Change of Control Notice is delivered (or an event shall have occurred that would require the delivery of a Change of Control Notice), on and after the date of delivery of such Change of Control Notice (or the date of the event that gives rise to the requirement to deliver such a Change of Control Notice), the Purchaser shall not be obligated to consummate any further Later Investments, but rather shall have the right to consummate any Later Investments in its sole discretion.

If the Acquisition Consideration is in the form of cash, the Purchaser shall not be required to tender the price specified in the Contingent Later Investment Notice, but shall receive an amount in connection with such Change of Control equal to the Acquisition Consideration applicable to the Purchaser based on the number of shares of Common Stock the Purchaser would have held had it consummated the Later Investment on the Business Day immediately preceding the date on which such Change of Control occurs, less the price specified in such Contingent Later Investment Notice.

(f) “Change of Control” means (i) acquisition of the Company by means of merger or other form of corporate reorganization in which outstanding shares of the Company are exchanged for securities or other consideration issued, or caused to be issued, by the Acquiring Person (as hereinafter defined) or its Parent, Subsidiary or Affiliate (each as defined in Rule 12b-2 of the Exchange Act), restructuring by the Company where outstanding shares of the Company are exchanged for shares of the Acquiring Person on a one-for-one basis and, immediately following the exchange, former stockholders of the Company own all of the outstanding shares, (ii) a sale of all or substantially all of the assets of the Company (on a consolidated basis) in a single transaction or series of related transactions, (iii) any tender offer, exchange offer, stock purchase or other transaction or series of related transactions by the Company in which the power to cast the majority of the eligible votes at a meeting of the Company’s stockholders at which directors are elected is transferred to a single entity or group acting in concert, or (iv) a capital reorganization or reclassification of the Common Stock pursuant to which the shareholders of the Company immediately prior to such reorganization or reclassification do not beneficially own at least sixty-five percent (65%) of each class of voting securities of the Company outstanding immediately following such reorganization or reclassification. Notwithstanding anything contained herein to the contrary, the change in the state of incorporation of the Company shall not in and of itself constitute a Change of Control.

No Person acquiring Common Stock from Purchaser pursuant to a public market purchase will thereby obtain any of the rights contained in this Agreement. This Agreement, together with the Warrant and that certain Non-Disclosure Agreement dated as of October 23, 2007, by and between the Company and Purchaser, constitutes the entire agreement and supersedes all prior agreements and understandings, both written and oral, between the parties hereto with respect to the subject matter of this Agreement. Except as provided in this Section 20(b), this Agreement is not intended to confer upon any Person other than the parties hereto any rights or remedies hereunder.

(c) This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of New York, and each of the parties hereto hereby submits to the non-exclusive jurisdiction of any state or federal court in the Southern District of New York and any court hearing any appeal therefrom, over any suit, action or proceeding against it arising out of or based upon this Agreement (a “Related Proceeding”). Each of the parties hereto hereby waives any objection to any Related Proceeding in such courts whether on the grounds of venue, residence or domicile or on the ground that the Related Proceeding has been brought in an inconvenient forum.

(d) Each party represents and acknowledges that, in the negotiation and drafting of this Agreement and the other instruments and documents required or contemplated hereby, it has been represented by and relied upon the advice of counsel of its choice.

Therefore, each party agrees that no rule of construction to the effect that any ambiguities are to be resolved against the drafter shall be employed in the interpretation of this Agreement and such other instruments and documents.

(e) Without prejudice to other rights or remedies hereunder (including any specified interest rate), and except as otherwise expressly set forth herein, interest shall be due on any amount that is due pursuant to this Agreement and has not been paid when due, calculated for the period from and including the due date to but excluding the date on which such amount is paid at the prime rate of U.S. money center banks as published in The Wall Street Journal (or if The Wall Street Journal does not exist or publish such information, then the average of the prime rates of three (3) U.S. money center banks agreed to by the parties) plus two percent (2%).

(f) Purchaser and the Company stipulate that the remedies at law of the parties hereto in the event of any default or threatened default by either party in the performance of or compliance with any of the terms of this Agreement and the Warrant are not and will not be adequate and that, to the fullest extent permitted by law, such terms may be specifically enforced by a decree for the specific performance of any agreement contained herein or by an injunction against a violation of any of the terms hereof or otherwise.

(g) Any and all remedies set forth in this Agreement or the Warrant: (i) shall be in addition to any and all other remedies Purchaser or the Company may have at law or in equity, (ii) shall be cumulative, and (iii) may be pursued successively or concurrently as each of Purchaser and the Company may elect. The exercise of any remedy by Purchaser or the Company shall not be deemed an election of remedies or preclude Purchaser or the Company, respectively, from exercising any other remedies in the future.

(h) The Company agrees that the parties have negotiated in good faith and at arms’ length concerning the transactions contemplated herein, and that Purchaser would not have agreed to the terms of this Agreement without each and every of the terms, conditions, protections and remedies provided herein and the Warrant. Except as specifically provided otherwise in this Agreement and the Warrant, the Company’s obligations to indemnify and hold Purchaser harmless in accordance with Section 17 of this Agreement are obligations of the Company that the Company promises to pay to Purchaser when and if they become due. The Company shall record any such obligations on its books and records in accordance with U.S. generally accepted accounting principles.

(i) This Agreement may be amended, modified or supplemented in any and all respects, but only by a written instrument signed by Purchaser and the Company expressly stating that such instrument is intended to amend, modify or supplement this Agreement.

(j) Each of the parties will cooperate with the others and use its best efforts to prepare all necessary documentation, to effect all necessary filings, and to obtain all necessary permits, consents, approvals and authorizations of all governmental bodies and other third-parties necessary to consummate the transactions contemplated by this Agreement.

(k) For purposes of this Agreement, except as otherwise expressly provided or unless the context otherwise requires: (i) the terms defined in this Agreement have the meanings assigned to them in this Agreement and include the plural as well as the singular, and the use of any gender herein shall be deemed to include the other gender and neuter gender of such term; (ii) accounting terms not otherwise defined herein have the meanings assigned to them in accordance with U.S. generally accepted accounting principles; (iii) references herein to “Articles”, “Sections”, “Subsections”, “Paragraphs” and other subdivisions without reference to a document are to designated Articles, Sections, Subsections, Paragraphs and other subdivisions of this Agreement, unless the context shall otherwise require; (iv) a reference to a Subsection without further reference to a Section is a reference to such Subsection as contained in the same Section in which the reference appears, and this rule shall also apply to Paragraphs and other subdivisions; (v) the words “herein”, “hereof”, “hereunder” and other words of similar import refer to this Agreement as a whole and not to any particular provision; (vi) the term “include” or “including” shall mean without limitation; (vii) the table of contents to this Agreement and all section titles or captions contained in this Agreement or in any Schedule or Annex hereto or referred to herein are for convenience only and shall not be deemed a part of this Agreement and shall not affect the meaning or interpretation of this Agreement; (viii) any agreement, instrument or statute defined or referred to herein means such agreement, instrument or statute as from time to time amended, modified or supplemented, including (in the case of agreements or instruments) by waiver or consent and (in the case of statutes) by succession of comparable successor statues and references to all attachments thereto and instruments incorporated therein; and (ix) references to a Person are also to its permitted successors and assigns and, in the case of an individual, to his or her heirs and estate, as applicable.

(l) If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or public policy all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect. If the final judgment of a court of competent jurisdiction or other authority declares that any term or provision hereof is invalid, void or unenforceable, the parties agree that the court making such determination shall have the power to reduce the scope, duration, area or applicability of the term or provision, to delete specific words or phrases, or to replace any invalid, void or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

(m) Time shall be of the essence in this Agreement.

(n) All dollar ($) amounts set forth herein and in the Warrant refer to United States dollars. All payments hereunder and thereunder will be made in lawful currency of the United States of America.

(o) Notwithstanding anything herein to the contrary, all measurements and references related to share prices and share numbers herein will be, in each instance, appropriately adjusted for stock splits, recombinations, stock dividends and the like.

The “Warrant Price” means the Later Investment Price with respect to the first Later Investment Closing to occur plus forty cents ($0.40) per share, less the Dividend Amount, subject to adjustment as set forth herein. The Warrants may be exercised (in whole or in part) at any time or from time to time after 12:01 A.M., New York City time, on the date of the Agreement (the “Commencement Date”) until 11:59 P.M., New York City time, on the date that is seven (7) years after and excluding the last Later Investment Closing Date, subject to extension pursuant to the Agreement (the period of time from the Commencement Date to such date, the “Warrant Term”).

(b) Manner of Exercise.

(i) The Warrants may be exercised by the Holder, in whole or in part, from time to time, on any day during the Warrant Term, by delivery of a notice in substantially the form attached to this Certificate (or a reasonable facsimile thereof) duly executed by the Holder (a “Warrant Exercise Notice”).

(ii) The Warrant Exercise Notice shall designate the number of shares of Common Stock to be received upon such exercise and the aggregate Warrant Price to be paid (or deemed paid in the case of Cashless Exercise), which shall be at least the lesser of (i) One Million Dollars ($1,000,000) and (ii) the aggregate Warrant Price for all shares that may then be purchased under the Warrant. The closing of each exercise shall take place (i) on the third (3^rd) Business Day after and excluding the date of the Warrant Exercise Notice or (ii) any other date upon which the exercising Holder and the Company mutually agree (the “Warrant Closing Date”).

(c) Conditions to Closing.

(i) Holder’s Conditions to Closing. It shall be a condition to each Holder’s obligation to close on each Warrant Closing Date that each of the following is satisfied, unless waived by such Holder:

shall be true and correct as of such date; (B) the Company shall have complied in all material respects with all of the covenants and agreements in the Agreement and this Certificate; (C) the Company shall not possess any negative, material non-public information other than as shall have been filed with the SEC at least five (5) Business Days prior to and excluding such Warrant Closing Date; and (D) Holder shall have received on the date of such exercise a certificate of the Chief Executive Officer and the Principal Financial Officer of the Company dated such Warrant Closing Date and to such effect.

(B) On such Warrant Closing Date, the Company shall have delivered to Holder an opinion of counsel, the form and substance of which shall be reasonably satisfactory to Holder, dated the date of delivery.

(C) Company will keep the Registration Statement continuously effective through the end of the Later Investment Period and for so long as any Common Stock continues to be issuable upon exercise of the Warrant.

(ii) Company’s Conditions to Closing. The obligations of the Company hereunder are subject to the performance by Holder of its obligations hereunder and to the satisfaction (unless expressly waived in writing by the Company) of the additional conditions precedent that, on each Warrant Closing Date: (i) the representations and warranties made by Holder in the Agreement shall be true and correct; (ii) Holder shall have complied in all material respects with all the covenants and agreements in the Agreement; and (iii) Holder shall have delivered to the Company on each such date a certificate of an appropriate officer of Holder dated such date and to such effect.

(iii) Agreement to Cause Conditions to be Satisfied. The Company with respect to Section 1.3(a) and the Holder with respect to Section 1.3(b) shall each use commercially reasonable efforts to cause each of the foregoing conditions to be satisfied at the earliest possible date.

(iv) Withdrawal of Notice. If the conditions set forth in Section 1.3(a) are not satisfied or waived prior to the second (2nd) Business Day following and excluding the Warrant Exercise Notice Date (except for those conditions which by their terms can be satisfied only on the Warrant Closing Date) or if the Company fails to perform its obligations on any Warrant Closing Date (including delivery of all shares of Common Stock issuable on such date) for any reason other than Holder’s failure to satisfy the conditions

required by Section 1.3(b), then in addition to all remedies available to Holder at law or in equity, such Holder may, at its sole option, and at any time, withdraw the Warrant Exercise Notice by written notice to the Company regardless of whether such condition has been satisfied or waived as of the withdrawal date and, after such withdrawal, shall have no further obligations with respect to such Warrant Exercise Notice and may submit an Warrant Exercise Notice on any future date with respect to such Warrants and the Warrant Price for such subsequent Warrant Exercise Notice shall be the lesser of (i) the Warrant Price in the withdrawn Warrant Exercise Notice and (ii) the Warrant Price in effect as of the subsequent Warrant Exercise Notice Date.

(d) When Exercise Effective.

Each exercise of any Warrant shall be deemed to have been effected on the Warrant Closing Date upon receipt of the relevant Warrant Price (or deemed to have been received in connection with Cashless Exercises), and the Person or Persons in whose name or names any certificate or certificates representing the Common Stock shall be issuable upon such exercise as provided in Section 1.5 shall be deemed to have become the holder(s) of record thereof.

(e) Delivery of Common Stock and Payment.

(i) Subject to Section 1.3, on the Warrant Closing Date, the Holder shall deliver payment in the amount designated as the “Designated Aggregate Exercise Price” by the holder in the Warrant Exercise Notice, and such Holder shall thereupon be entitled to receive the number of duly authorized, validly issued, fully paid and nonassessable shares of Common Stock designated in the Warrant Exercise Notice, delivered as set forth in Section 1.7.

(ii) Notwithstanding subsection (a) above, if any of the following occurs or is true:

(A) the actual number of shares of Common Stock issued pursuant to the Agreement and this Certificate and the number of shares of Common Stock issuable pursuant to the Agreement and this Certificate (which number shall be calculated assuming consummation of the Initial Investment and all Later Investments (as defined in the Agreement) and exercise of all Warrants, in each case at an Initial Investment Price (as defined in the Agreement), Later Investment Price (as defined in the Agreement) or Warrant Price, as the case may, that has been determined in accordance with the terms hereof or the Agreement, as the case may

be or, if not yet determined, at the relevant price per share computed as of the date on which the Initial Investment Notice (as defined in the Agreement), Later Investment Notice (as defined in the Agreement) or Warrant Exercise Notice, as the case may be, is delivered) exceeds Nine Million Three Hundred Twenty Nine Thousand Two Hundred Ninety Three (9,329,293) without regard to the Maximum Number then in effect;

(B) the Registration Statement is not effective or otherwise not available; or

(C) the Holder shall have received a Change of Control Notice from the Company (as defined in the Agreement) or an event shall have occurred that would require the Company to deliver a Change of Control Notice, in each case at any time on or before the date of the Warrant Exercise Notice,

then the exercising Holder may elect to receive an amount of Common Stock (the “Settlement Stock”) equal to “X” where:

X = [(N x D) — (N x P)] / P

N = the gross number of shares of Common Stock that would have been issuable on the relevant Warrant Closing Date if the Holder had not elected Cashless Exercise

D = Daily Market Price on the third (3rd) Business Day before, and excluding, the Warrant Closing Date

P = Warrant Price with respect to such Warrant Exercise Notice

The Settlement Stock shall be issued by the Company to Holder upon the Warrant Closing Date in lieu of the number of shares of Common Stock otherwise issuable upon exercise of the Warrants covered by such Warrant Exercise Notice, provided, that the Holder shall not be required to tender the Warrant Price otherwise payable (a “Cashless Exercise”).

(iii) Closing of Cashless Exercise. The Company shall close a Cashless Exercise on the relevant Warrant Closing Date. The Company shall issue and deliver the Settlement Stock pursuant to Section 1.7 on the relevant Warrant Closing Date. Upon receipt of the Settlement Stock in connection with any Cashless Exercise, (i) that amount of Warrants as specified for exercise in the Warrant Exercise Notice shall be deemed exercised and (ii) that amount of cash that would have been paid by the Purchaser on the relevant Warrant Closing Date if the Holder had not elected Cashless Exercise shall be deemed paid by the Holder and received by the Company.

(iv) Effect on 19.99% Limit Calculation. In determining whether the 19.99% Limit described in Section 7(a) of the Agreement has been reached, computation shall be made based on the number of shares of Settlement Stock actually issued in the case of a Cashless Exercise.

(f) Extension of Term.

(i) The Warrant Term shall be extended: by two (2) Business Days for each Business Day:

(A) that the Registration Statement is not effective and available for the issuance of all Common Stock issuable under this Certificate; or

(B) occurring during the period (x) commencing on the earlier of the day on which the Company restates or announces its intention to restate any portion of the Company Financial Statements., and (b) ending on the Restatement Filing Date (as defined in the Agreement).

(ii) To the extent that the Company (i) restates or announces its intention to restate any portion of the Company Financial Statements or (ii) fails to maintain the effectiveness and availability of the Registration Statement for the issuance of all Common Stock issuable under this Certificate, in either case, within sixty-five (65) Business Days of the expiration of the Warrant Term, the Warrant Term shall be extended to a date that is at least sixty-five (65) Business Days after the later of the Restatement Filing Date or the remediation of the failure described in clause (ii).

(g) Delivery of Common Stock.

(i) On the Warrant Closing Date, the Company at its expense (including payment by it of any applicable issue taxes) shall cause to be issued in the name of and delivered to the exercising Holder or as such Holder may direct, at the election of such Holder, (i) at such address specified by such Holder via reputable overnight courier, one or more certificates for, or (ii) via the Depository Trust Company’s Deposit and Withdrawal at Custodian (or DWAC) system the number of duly authorized, validly issued, fully paid and non-assessable shares of Common Stock to which such Holder shall be entitled upon such exercise plus, in lieu of any fractional share of Common Stock to which such Holder would otherwise be entitled, cash in an amount equal to the same fraction of the Daily Market Price on the Business Day immediately preceding the relevant Warrant Closing Date, and a certificate from the Company stating the remaining number of shares of Common Stock for which this Warrant may be exercised.

2. Reservation of Shares.

For so long as the Warrant Amount represented hereby has not been exercised in full, the Company shall at all times prior to the end of the Warrant Term reserve and keep available, free from pre-emptive rights, out of its authorized but unissued capital stock, the number of shares available for exercise hereunder. In the event the number of shares of Common Stock or other securities issuable exceeds the authorized number of shares of Common Stock or other securities, the Company shall promptly take all actions necessary to increase the authorized number, including causing its board of directors to call a special meeting of stockholders and recommend such increase.

3. Accountants’ Report as to Adjustments.

In each case of any adjustment or readjustment of the Warrant Amount, the Warrant Term, the Warrant Price or any other adjustment or readjustment pursuant to the terms of the Agreement or this Certificate, or upon the written request at any time of any Holder, the Company at its expense will promptly compute such adjustment or readjustment (the “Company Calculation”) in accordance with the terms of this Certificate and the Agreement and cause the Company’s Principal Financial Officer to verify such computation and prepare a report setting forth such adjustment or readjustment and showing in reasonable detail the method of calculation thereof and the facts upon which such adjustment or readjustment is based, including a statement of (a) the Warrant Amount, (b) the Warrant Term and (c) the Warrant Price in effect immediately prior to such adjustment or readjustment (as adjusted and readjusted, as applicable). The Company will forthwith deliver a copy of each such report to each Holder and will also keep copies of all such reports at its principal office and will cause the same to be available for inspection at such office during normal business hours by any Holder. The Holder may dispute the Company Calculation by providing its computation of such adjustment or readjustment (the “Holder

Calculation”) and requesting in writing that independent certified public accountants of recognized national standing (which may be the regular auditors of the Company) selected by the Company verify the Company Calculation. The Holder shall be responsible for the costs and expenses of such accountants if the difference between the computation of the adjustment or readjustment by such accountants (the “Accountant Calculation”) and the Holder Calculation is greater than the difference between the Accountant Calculation and the Company Calculation, and otherwise the Company shall bear such costs and expenses.

4. Taxes.

The Company shall pay all documentary stamp taxes (if any) attributable to the issuance of Common Stock upon each exercise of the Warrants by the Holder; provided, however, that the Company shall not be required to pay any tax or taxes which may be payable in respect of any transfer involved in the registration of any certificates for Common Stock in a name other than that of a Holder upon each exercise of Warrants, and the Company shall not be required to issue or deliver a Certificate evidencing Warrants or certificates for Common Stock unless or until the person or persons requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the reasonable satisfaction of the Company that such tax has been paid.

5. Treatment of Company Stock Adjustment Events.

In case the Company may effect any subdivision or combination of the issued Common Stock, whether by reason of any dividend or distribution of units, split, recapitalization, reorganization, spin-off, combination or other similar change (each a “Company Stock Adjustment Event”), including a pro rata distribution of Common Stock to all Holders of Common Stock, or a subdivision or combination of the outstanding Common Stock, then (a) in the case of any such distribution, immediately after the close of business on the record date for the determination of Holders of any class of securities entitled to receive such distribution, or (b) in the case of any such subdivision or combination, at the close of business on the Business Day immediately prior to the Business Day upon which such Company action becomes effective, the Warrant Price, the Prevailing Price and, to the extent applicable, the Daily Market Price and each other price or quantity in effect immediately prior to such Company Stock Adjustment Event shall be proportionately changed.

(a) Business Combinations.

(i) If after the date of this Certificate, a Business Combination or plan or proposal with respect thereto is publicly announced or occurs, as part of such Business Combination, proper provision shall be made as follows:

(1) Between the date a Business Combination is announced and the effective date of the Business Combination, each Holder at its sole option shall continue to have the right to submit to the Company a Warrant Exercise Notice in accordance with the terms and conditions of this Certificate. In addition, each Holder at its sole option may elect to submit to the Company a special notice (a “Contingent Warrant Exercise Notice”) to exercise all or part of its unexercised Warrants (including any increase in the Warrant Amount contingent upon any Later Investment Closing for which a Contingent Later Investment Exercise Notice has been submitted) in connection with such Business Combination; in which case, notwithstanding the provisions of Section 1.4:

1 the effectiveness of such contingent exercise shall be conditional upon the effectiveness of the Business Combination;

2 such Holder shall have the right to deliver a notice to withdraw such Contingent Warrant Exercise Notice until the effective date of such Business Combination; and

3 if such Contingent Warrant Exercise Notice shall not have been withdrawn, then on the effective date of such Business Combination, the Holder of such Warrants shall receive, upon payment of the Warrant Price designated in the Warrant Exercise Notice, the same consideration, in the form of cash, securities or other assets (the “Acquisition Consideration”) per share of Common Stock issuable to any other holder of shares of Common Stock in connection with such Business Combination based upon the number of shares of Common Stock into which such Holder’s Warrants would be exercisable if such Holder had exercised each Warrant on the Business Day

immediately preceding the date on which such Business Combination occurs. Upon receipt of the Warrant Price, such Holder’s Warrants tendered for exercise pursuant to a Warrant Exercise Notice or Contingent Warrant Exercise Notice shall be fully exercised and shall no longer permit such Holder to exercise such Warrants into Common Stock; provided, that if the Acquisition Consideration is in the form of cash, the Holder shall not be required to tender the relevant Warrant Price to exercise its Warrants, but shall receive an amount in connection with such Business Combination equal to the Acquisition Consideration applicable to such Holder based on the number of shares of Common Stock into which such Holder’s Warrants would be exercisable if such Holder had exercised each Warrant that it owns on the Business Day immediately preceding the date on which such Business Combination occurs, less such Warrant Price.

(ii) In the case of any Business Combination, the Company shall not enter into an agreement with the Acquiring Person resulting in a Business Combination unless such Agreement expressly obligates the Acquiring Person to assume all of the Company’s obligations under any unexercised Warrants (the “Stock Assumption Agreement”). In the event that any Warrant remains unexercised upon consummation of the Business Combination, the Holder thereof shall thereafter automatically have equivalent rights with respect to the Acquiring Person and from and after the effective date of the Business Combination and under such Stock Assumption Agreement (i) all references to the Company in this Certificate shall be references to the Acquiring Person, (ii) all references to Common Stock in this Certificate shall be references to the securities for which the Common Stock are exchanged in the Business Combination (or if none, the most widely-held class of voting securities of the Acquiring Person), (iii) all references to the Warrant Price in this Certificate shall be references to the Stock Adjustment Measuring Price (as defined below), and (iv) all references to the Prevailing Price and Warrant Price shall be references to such prices with respect to the Acquiring Person.

(iii) “Acquiring Person” means, in connection with any Change of Control, (i) the continuing or surviving Person of a consolidation or merger with the Company (if other than the Company), (ii) the transferee of all or substantially all of the properties or assets of the Company, (iii) the corporation consolidating with or merging into the Company in a consolidation or merger in connection with which the Common Stock is changed into or

exchanged for stock or other securities of any other Person or cash or any other property, (iv) the entity or group acting in concert acquiring or possessing the power to cast the majority of the eligible votes at a meeting of the Company’s stockholders at which directors are elected, or, (v) in the case of a capital reorganization or reclassification of the Common Stock pursuant to which the shareholders of the Company immediately prior to such reorganization or reclassification do not beneficially own at least sixty-five percent (65%) of each class of voting securities of the Company outstanding immediately following such reorganization or reclassification, the Company, or (vi) at Purchaser’s election, any Person that (A) controls the Acquiring Person directly or indirectly through one or more intermediaries, (B) is required to include the Acquiring Person in the consolidated financial statements contained in such Person’s Annual Report on Form 10 K (if such Person is required to file such a report) or would be required to so include the Acquiring Person in such Person’s consolidated financial statements if they were prepared in accordance with U.S. generally accepted accounting principles and (C) is not itself included in the consolidated financial statements of any other Person (other than its consolidated subsidiaries).

(iv) “Change of Control” means (a) acquisition of the Company by means of merger or other form of corporate reorganization in which outstanding shares of the Company are exchanged for securities or other consideration issued, or caused to be issued, by the Acquiring Person or its Parent, Subsidiary or Affiliate (each as defined in Rule 12b-2 of the Exchange Act), other than a restructuring by the Company where outstanding shares of the Company are exchanged for shares of the Acquiring Person on a one-for-one basis and, immediately following the exchange, former stockholders of the Company own all of the outstanding shares, (b) a sale of all or substantially all of the assets of the Company (on a consolidated basis) in a single transaction or series of related transactions, (c) any tender offer, exchange offer, stock purchase or other transaction or series of related transactions by the Company in which the power to cast the majority of the eligible votes at a meeting of the Company’s stockholders at which directors are elected is transferred to a single entity or group acting in concert, or (d) a capital reorganization or reclassification of the Common Stock pursuant to which the shareholders of the Company immediately prior to such reorganization or reclassification do not beneficially own at least sixty-five percent (65%) of each class of voting securities of the Company outstanding immediately following such reorganization or reclassification. Notwithstanding anything contained herein to the contrary, a change in the state of incorporation of the Company shall not in and of itself constitute a Change of Control.

(v) “Stock Adjustment Measuring Price” means the Warrant Price multiplied by a fraction, (i) the numerator of which is the Daily Market Price and (ii) the denominator of which is the volume-weighted average price, calculated to the nearest ten thousandth (i.e., four decimal places (.xxxx)), of the securities for which Common Stock is exchanged in the Business Combination (or if none, the most widely-held class of voting securities of the Acquiring Person), in each case determined as of the Business Day immediately preceding and excluding the date on which the Business Combination is consummated.

(b) Adjustment for Restatements.

From and after the date that any Holder delivers a Restatement Adjustment Notice (as defined in the Agreement) to the Company, each subsequent Warrant Price shall equal the lesser of (a) the Warrant Price calculated without regard to such Restatement Adjustment Notice and (b) the Restatement Price (as defined in the Agreement) specified in such Restatement Adjustment Notice less the fair market value of all dividends, distributions and other payments or issuances declared or paid by the Company per share of Common Stock on and after the Agreement Closing Date determined as of the date of each such declaration (the “Dividend Amount”); provided that to the extent that any dividend constitutes a Company Stock Adjustment Event, such dividend shall be disregarded from the calculation of the Dividend Amount.

(c) Adjustment for Future Equity Issuances.

From and after the date that the Company delivers any Equity Issuance Notice to any Holder (or from and after the date on which a disclosure or consummation described in Section 9(b) of the Agreement has occurred that requires the Company to deliver an Equity Issuance Notice), each subsequent Warrant Price shall equal the lesser of (a) the Warrant Price calculated without regard to such Price Adjustment Notice and (b) the Later Issuance Price (as defined in the Agreement) specified in such Equity Issuance Notice less the Dividend Amount.

6. Lost or Stolen Certificate

In case this Certificate shall be mutilated, lost, stolen or destroyed, the Company may in its discretion issue in exchange and substitution for and upon cancellation of the mutilated Certificate, or in lieu of and substitution for the Certificate lost, stolen or destroyed, a new Certificate of like tenor, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction of such Certificate and indemnity, if requested, reasonably satisfactory to the Company. Applicants for a substitute Certificate shall also comply with such other reasonable regulations and pay such other reasonable charges as the Company may prescribe.

7. Transfer Agent.

(i) Initially, the Company (and upon a Business Combination, the Acquiring Person) shall serve as the transfer agent (the “Transfer Agent”) for the Warrants. The Transfer Agent shall at all times maintain a register (the “Stock Register”) of the Holders of the Warrants. The Company may deem and treat each Holder of Warrants as set forth in the Stock Register as the true and lawful owner thereof for all purposes, and the Company shall not be affected by any notice to the contrary.

(ii) The Company may, at any time and from time to time, appoint another Person to serve as the Transfer Agent, and shall upon acceptance by such Person, give notice to each Holder of the change in Transfer Agent. Such new Transfer Agent shall be (a) a Person doing business and in good standing under the laws of the United States or any state thereof, and having a combined capital and surplus of not less than Fifty Million Dollars ($50,000,000) or (b) an affiliate of such a Person. The combined capital and surplus of any such new Transfer Agent shall be deemed to be the combined capital and surplus as set forth in the most recent report of its condition published by such Transfer Agent prior to its appointment; provided that such reports are published at least annually pursuant to law or to the requirements of a federal or state supervising or examining authority. After acceptance in writing of such appointment by the new Transfer Agent, it shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as the Transfer Agent, without any further assurance, conveyance, act or deed; but if for any reason it shall be reasonably necessary or expedient to execute and deliver any further assurance, conveyance, act or deed, the same shall be done at the expense of the Company and shall be legally and validly executed and delivered by the Company. Any Person into which any new Transfer Agent may be merged or any Company resulting from any consolidation to which any new Transfer Agent shall be a party or any Company to which any new Transfer Agent transfers substantially all of its corporate trust or stockholders services business shall be a successor Transfer Agent under this Certificate without any further act; provided that such Person (a) would be eligible for appointment as successor to the Transfer Agent under the provisions of this Section 7 or (b) is a wholly owned subsidiary of the Transfer Agent. Any such successor Transfer Agent shall promptly cause notice of its succession as Transfer Agent to be delivered via reputable overnight courier to the Holders of the Warrants at such Holder’s last address as shown on the Stock Register.

8. Notices.

AMENDMENT TO
SECOND AMENDED AND RESTATED RIGHTS AGREEMENT

Section 11(a)(iii) shall be deleted and replaced with the following:

(iii) In the event that the number of shares of Common Stock that are authorized by the Company’s certificate of incorporation but not outstanding or reserved for issuance for purposes other than upon exercise of the Rights is not sufficient to permit the exercise in full of the Rights in accordance with the foregoing subparagraph (ii) of this Section 11(a), the Company shall, to the extent permitted by applicable law and regulation, (A) determine the excess of (1) the value of the Adjustment Shares issuable upon the exercise of a Right (computed using the Current Market Price used to determine the number of Adjustment Shares) (the “Current Value”) over (2) the Purchase Price (such excess is herein referred to as the “Spread”), and (B) with respect to each Right, make adequate provision to substitute for the Adjustment Shares, upon the exercise of the Rights and payment of the applicable Purchase Price, (1) cash, (2) a reduction in the Purchase Price, (3) Common Stock or other equity securities of the Company (including, without limitation, shares, or units of shares, of preferred stock (including, without limitation, the Preferred Stock) that the Board of Directors of the Company has determined to have the same value as shares of Common Stock (such shares of preferred stock are herein referred to as “Common Stock Equivalents”)), (4) debt securities of the Company, (5) other assets or (6) any combination of the foregoing, having an aggregate value equal to the Current Value, where such aggregate value has been determined by the Board of Directors of the Company based upon the advice of a nationally recognized investment banking firm selected by the Board of Directors of the Company; provided, however, if the Company shall not have made adequate provision to deliver value pursuant to clause (B) above within 30 days following the later of (x) the first occurrence of a Flip-In Event and (y) the date on which the Company’s right of redemption pursuant to Section 23(a) expires (the later of (x) and (y) being referred to herein as the “Flip-In Trigger Date”), then the Company shall be obligated to deliver, upon the surrender for exercise of a Right and without requiring payment of the Purchase Price, shares of Common Stock (to the extent not outstanding or reserved for issuance for purposes other than upon exercise of the Rights) and then, if necessary, cash, which shares and/or cash have an aggregate value equal to the Spread. If the Board of Directors of the Company shall determine in good faith that it is likely that sufficient additional shares of Common Stock could be authorized for issuance upon exercise in full of the Rights, the 30-day period set forth above may be extended to the extent necessary, but not more than 90 days after the Flip-In Trigger Date, in order that the Company may seek stockholder approval for the authorization of such additional shares (such period, as it may be extended, the “Substitution Period”). To the extent that the Company or the Board of Directors determines that some action need be taken pursuant to the first and/or second sentences of this Section 11(a)(iii), the Company (x) shall provide, subject to Section 7(e) hereof, that such action shall apply uniformly to all outstanding Rights, and (y) may suspend the exercisability of the Rights until the expiration of the Substitution Period in order to seek

any authorization of additional shares and/or to decide the appropriate form of distribution to be made pursuant to such first sentence and to determine the value thereof. In the event of any such suspension, the Company shall issue a public announcement stating that the exercisability of the Rights has been temporarily suspended, as well as a public announcement at such time as the suspension is no longer in effect. For purposes of this Section 11(a)(iii), the value of the Common Stock shall be the Current Market Price per share of the Common Stock on the Flip-In Trigger Date and the value of any Common Stock Equivalent shall be deemed to have the same value as the Common Stock on such date.
