ARTICLE IV.
OTHER AGREEMENTS OF THE PARTIES

4.1 [Intentionally Omitted]

4.2 Limits on Shares Issuable and Held.

(a) The Purchaser covenants and agrees with the Company that neither the Purchaser, nor any of its Tax Affiliates will at any time, directly, together with or through Persons who have a formal or informal understanding to make a coordinated acquisition of stock with the Purchaser or its Tax Affiliates, acquire, offer to acquire, or agree to acquire, by purchase or otherwise, any shares of stock (as defined in Temporary Treasury Regulation Section 1.382-2T(f)(18) or any successor provision) of the Company, including any Common Stock acquired hereunder or pursuant to the Warrants, if, as a result of such acquisition, it would not be able to make the representations and warranties contained in Section 3.2(d) hereof or issue any Affidavit described in Section 4.2(d) hereof.

(b) Any transfer of Common Stock or exercise or transfer of the Warrants that results in a breach of Section 4.2(a) hereof shall be void ab initio and without force or effect (a “Purported Transfer”). The Purchaser and the Company covenant and agree to take all steps reasonably practicable to unwind any such transfer so as to return the transferee and transferor to the position they were in prior to the Purported Transfer.

(i) If the Purported Transfer is a public transaction and the Purchaser or a Tax Affiliate is the buyer, then the Purported Transfer shall be void ab initio with respect to the Purchaser or Tax Affiliate, and the Purchaser or Tax Affiliate immediately shall turn over the shares transferred in the Purported Transfer (the “Void Shares”) to the Company, which shall sell the Void Shares in the open market. If the proceeds of such sale are more than the amount paid by the buyer for the Void Shares, the Company shall return to the buyer only the amount paid by the buyer for the shares and any excess shall be contributed to the United States Treasury as a charitable contribution in respect of which no Person shall claim a deduction for tax purposes. If the Company receives less for the Void Shares than was paid by the buyer, the Company shall pay to the buyer only the amount received by the Company for the Void Shares and the Company shall have no further liability to the Purchaser, the buyer, if not the Purchaser, or to any other Person.

(ii) If the Purported Transfer is not a public transaction, the Purchaser shall take all steps reasonably practicable within its power to cause the transaction to be rescinded, including reimbursing any party to such transaction for any loss incurred as a result of such rescission. If the Purchaser is unable to cause the rescission of the Purported Transfer and the Purchaser or a Tax Affiliate is the buyer in the Purported Transfer, the Purported Transfer shall be treated the same as a public transaction and shall have all of the consequences of a Purported Transfer that is a public transaction described in the preceding clause (i).

(c) In connection with any transfer by the Purchaser or a Tax Affiliate in a non-public transaction, the Purchaser or Tax Affiliate shall obtain (i) a representation or warranty from the transferee substantially to the same effect as the representation and warranty set forth in Section 3.2(d) hereof, which shall expressly state that it may be relied upon by the Company and (ii) covenants and affidavits from the transferee substantially to the same effect as the Tax Covenants and Affidavits provided for herein, which shall expressly state that the Company shall be the beneficiary of such covenants.

(d) Within 90 days after the end of each fiscal year of the Company, if the Purchaser or a Tax Affiliate owned any Common Stock during such fiscal year, and at the time of each Subsequent Closing and exercise or transfer of a Warrant, the Purchaser (or, in the case of a Warrant transfer, the transferor and transferee of the Warrant) shall provide the Company with an affidavit, attesting that at no time during the preceding fiscal year (in the case of the affidavit after the end of the fiscal year) or immediately before and immediately after the Subsequent Closing, transfer of a Warrant or issuance of shares pursuant to a Warrant (in the case of the Subsequent Closing or transfer or exercise of a Warrant) was the Purchaser and its Tax Affiliates (treated in the aggregate) a “5-percent shareholder” (as the term is defined under Section 382 of the Code treating, for this purpose, the Purchaser and its Tax Affiliates in the aggregate as one individual (and, separately, in the case of a transfer of a Warrant, treating the transferee and its Tax Affiliates in the aggregate as one individual and, separately, treating the transferor and its Tax Affiliates in the aggregate as one individual)), in each case, based on the number of outstanding shares determined in the manner provided in Section 3.2(d)(i)(D) (an “Affidavit”). For the first fiscal year in which the Purchaser and its Tax Affiliates owned no Common Stock at any time during such fiscal year, the Purchaser shall so attest in an Affidavit within 90 days after the end of such fiscal year; and for each fiscal year thereafter, the Purchaser and its Tax Affiliates shall have no duty to provide an Affidavit, unless and until an Affidavit is again required by the first sentence of this clause (d). The attestations of all Affidavits made pursuant to this Section 4.2(d) shall be made under penalty of perjury.

(e) The Purchaser shall not be bound by the terms and provisions of any so-called “poison pill” or other arrangement intended to protect the unrestricted use of the Company’s tax net operating loss carryforwards, that are any more restrictive on the Purchaser than the provisions of this Agreement. For the avoidance of doubt, this Section 4.2(e) shall not be construed to apply (i) to any transferee of Common Stock or Warrants from the Purchaser and (ii) to any Person other than the Purchaser, including any person to whom Common Stock held by the Purchaser would be attributed pursuant to Section 382 of the Code.

(f) In the event that the Purchaser attempts to acquire Subsequent Closing Shares (including associated Warrants) or exercise Warrants but is limited by Section 4.2(a) from doing so, the Purchaser may nonetheless exercise its right to acquire Subsequent Closing Shares (including associated Warrants) and/or exercise Warrants at a later date, subject to the terms and conditions of this Agreement and/or the Warrants.

(g) Notwithstanding anything in this Agreement or the Warrants to the contrary, the parties hereby agree that (i) (A) any deliberate and intentional violation by the Purchaser of Section 3.2(d) or the Tax Covenants would result in actual, direct and foreseeable damages to the Company, for which the Company may seek all available legal and equitable remedies, provided that conduct shall be treated as “deliberate and intentional” if such conduct was undertaken without the exercise of reasonable diligence with respect to such conduct, provided further, however, that the exercise of reasonable diligence does not include having to inquire into facts that would not have been taken into account under Treasury Regulations Section 1.382-2T in the absence of actual knowledge of such facts, but (B) that the Company shall be entitled to seek only specific performance of Section 3.2(d) or the Tax Covenants (and not a financial remedy) for any other actual or alleged violation of such provisions, this clause (g)(i)(B) being intended as an express limitation-of-remedies provision enforceable by the Purchaser, its Affiliates and

any Tax Affiliate; (ii) no repurchase or redemption of shares of capital stock by the Company shall result in any breach by the Purchaser, its Affiliates or any Tax Affiliate of this Agreement or the Warrants, provided, that for purposes of any subsequent calculation of percentage ownership under this Agreement or the Warrant, the Purchaser, its Affiliates and its Tax Affiliates take into account the number of shares of Common Stock outstanding as provided in Section 3.2(d)(i)(D); (iii) Section 3.2(d) and the Tax Covenants and related provisions of this Agreement and the Warrants shall not apply in connection with or following a Change of Control, provided that such Change of Control would result in an ownership change (as that term is defined under Section 382 of the Code) without taking into account any acquisitions of shares by the Purchaser that would otherwise breach Section 3.2(d), the Tax Covenants or the related provisions of this Agreement and the Warrants; and (iv) Section 3.2(d) and Section 4.2(e) shall cease to apply and the Tax Covenants shall terminate at such time that both (1) the Purchaser’s right to purchase Shares pursuant to Section 2.1(b) and its right to exercise any and all Warrants have expired, and (2) the Purchaser and the Tax Affiliates no longer own any Shares acquired pursuant to the terms of this Agreement or pursuant to the exercise of Warrants.

(h) The total number of shares of Common Stock that may be issued under this Agreement and the Warrants shall not exceed a number equal to nineteen and ninety-nine one-hundredths percent (19.99%) of the outstanding shares of Common Stock as of the date of this Agreement, as indicated in Section 3.1(k) hereof.

4.3 Registration Rights.

(a) No later than the Initial Closing Date, the Company shall, at its own expense, cause all of the Shares (including the Initial Closing Shares, Subsequent Closing Shares and Shares issuable upon exercise of the Warrants) and the Warrants (including the Initial Closing Warrant and all Subsequent Closing Warrants) to be included on the Existing Registration Statement and file a Prospectus Supplement thereunder.

(b) The Company will: (i) use its commercial best efforts to keep the Existing Registration Statement effective until such time as no additional Shares or Warrants may be issued pursuant to this Agreement and no additional Shares may be issued pursuant to the Warrants (such period, the Existing Registration Statement’s “Registration Period”); (ii) prepare and file with the SEC such amendments and supplements to the Existing Registration Statement and the prospectus used in connection with the Existing Registration Statement (as so amended and supplemented from time to time, the “Prospectus”) as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all Shares by the Purchaser or any of its Affiliates; (iii) furnish such number of Prospectuses and other documents incident thereto, including any amendment of or supplement to the Prospectus, as the Purchaser from time to time may reasonably request; (iv) cause all Shares to be listed on each securities exchange and quoted on each quotation service on which similar securities issued by the Company are then listed or quoted; and (v) otherwise comply with all applicable rules and regulations of the SEC, FINRA and Nasdaq.

(c) Notwithstanding anything else in this Section 4, if, at any time during which the Shares (including the Initial Closing Shares, Subsequent Closing Shares and Shares issuable upon the exercise of the Warrants) and the Warrants (including the Initial Closing Warrant and all Subsequent Closing Warrants) may be issued pursuant to the Existing Registration Statement or a Prospectus is required to be delivered in connection with the sale of any Shares, the Company determines in good faith and upon the advice of its outside legal counsel that a development has occurred or a condition exists as a result of which the Existing Registration Statement or the Prospectus contains a material misstatement or omission, or that a material transaction in which the Company is engaged or proposes to engage would require an immediate amendment to the Existing Registration Statement, a supplement to the Prospectus, or a filing under the Exchange Act or other public disclosure of material information and the disclosure of such transaction would be premature or injurious to the consummation of the transaction, the Company will immediately notify the Purchaser, and any permitted assignee of any Warrant or additional investment right under Section 2.1(b)(i), thereof by telephone and in writing. Upon receipt of such notification, all offers and sales of the Shares pursuant to the Existing Registration Statement shall be immediately suspended. In such event, the Company will amend or supplement the Existing Registration Statement and the Prospectus or make such filings or public disclosures as promptly as practicable and will take such other steps as may be required to permit sales of the Shares thereunder, in accordance with applicable federal and state securities laws. The Company will promptly notify the Purchaser after it has determined in good faith that such sales have become permissible in such manner and will promptly deliver copies of the Existing Registration Statement and the Prospectus (as so amended or supplemented, if applicable) to the Purchaser in accordance with this Section 4.3. Notwithstanding the foregoing, (i) under no circumstances shall the Company be entitled to exercise its right to suspend sales of any Shares more than twice in any twelve (12)-month period, (ii) the period during which such sales may be suspended (each a “Blackout Period”) at any time shall not exceed forty-five (45) calendar days, and (C) no Blackout Period may commence less than forty-five (45) calendar days after the end of the preceding Blackout Period.

4.4 Compliance. With respect to the acquisition, ownership and disposition of the Shares and Warrants issued and to be issued pursuant to the terms of this Agreement, the Purchaser shall use its commercial best efforts to comply with federal and state laws applicable to the Purchaser and rules and regulations of federal and state governmental or self-regulatory agencies and bodies, including, but not limited to, the SEC, FINRA and Nasdaq, applicable to the Purchaser.

4.5 Change of Control.

(a) If after the date of this Agreement and prior to the Expiration Date, a Change of Control or plan or proposal with respect thereto is publicly announced or occurs, and the Acquiring Person (or its direct or indirect parent entity) does not have a class of common equity securities listed or admitted for trading on any securities exchange or over-the-counter or other organized market, whether U.S. or not, then between the date such Change of Control is announced and the effective date of the Change of Control, but not thereafter, the Purchaser shall continue to have the right to submit to the Company a Purchaser Notice (which Purchaser Notice may, at the Purchaser’s option, specify that the Subsequent Closing shall occur simultaneously with, and be contingent upon, the occurrence of the Change of Control) in accordance with the terms and conditions of this Agreement; provided, however, that so long as the Company has provided the Purchaser with at least five (5) Business Days advance written notice of the closing date for the Change of Control, the Company shall not be required to postpone such closing date in order to facilitate the Subsequent Closing.

(b) If after the date of this Agreement and prior to the Expiration Date, a Change of Control or plan or proposal with respect thereto is publicly announced or occurs, and the Acquiring Person (or its direct or indirect parent entity) has a class of common equity securities listed or admitted for trading on any securities exchange or over-the-counter or other organized market, whether U.S. or not, then:

(i) Between the date such Change of Control is announced and the effective date of the Change of Control, the Purchaser shall continue to have the right to submit to the Company a Purchaser Notice (which Purchaser Notice may, at the Purchaser’s option, specify that the Subsequent Closing shall occur simultaneously with, and be contingent upon, the occurrence of the Change of Control) in accordance with the terms and conditions of this Agreement; provided, however, that so long as the Company has provided the Purchaser with at least five (5) Business Days advance written notice of the closing date for the Change of Control, the Company shall not be required to postpone such closing date in order to facilitate the Subsequent Closing;

(ii) The Company shall not enter into an agreement with the Acquiring Person resulting in such Change of Control unless such agreement expressly obligates the Acquiring Person to assume all of the Company’s obligations under this Agreement; and

(iii) In the event that any right to acquire shares pursuant to Section 2.1(b) hereof remains unexercised upon consummation of the Change of Control, the Purchaser shall thereafter automatically have equivalent rights with respect to the Acquiring Person, and from and after the effective date of the Change of Control and regardless of whether the Acquiring Person expressly assumes the Company’s obligations:

(A) all references to the Company in this Agreement shall be references to the Acquiring Person,

(B) all references to Common Stock in this Agreement shall be references to the securities for which the Common Stock are exchanged in the Change of Control (or if none, the most widely-held class of common equity securities of the Acquiring Person), and

(C) the Per Share Purchase Price shall be adjusted to equal the Per Share Purchase Price as in effect immediately prior to the Change of Control multiplied by a fraction, (1) the numerator 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 Change of Control (or if none, the most widely-held class of voting common equity securities of the Acquiring Person), and (2) the denominator of which is the Daily Market Price of the Company, in the case of (1) and (2) determined as of the Business Day immediately preceding and excluding the date on which the Change of Control is consummated. For purposes of this Agreement, “Daily Market Price” means, on any date, the amount per share of the Common Stock (or, for purposes of determining the Daily Market Price of the common stock of an Acquiring Person, the common stock of such Acquiring Person),

equal to (i) the daily volume-weighted average price, calculated to the nearest ten thousandth (i.e., four decimal places (.xxxx)), on Nasdaq or, if no sale takes place on such date, the average of the closing bid and asked prices, calculated to the nearest ten thousandth (i.e., four decimal places (.xxxx)), on Nasdaq on such date, in each case as reported by Bloomberg, L.P. (or by such other Person as the Purchaser and the Company may agree), or (ii) if such Common Stock (or the common stock of an Acquiring Person) is not then listed or admitted to trading on Nasdaq, the higher of (x) the book value per share thereof as determined by any firm of independent public accountants of recognized standing selected by Company and reasonably acceptable to the Purchaser as of the last calendar day of the most recent month ending before the date as of which the determination is to be made and (y) the fair market value per share thereof determined in good faith by an independent, nationally recognized appraisal firm selected by the Purchaser and reasonably acceptable to the Company (whose fees and expenses shall be borne by the Company), subject in each case to adjustment for stock splits, recombinations, stock dividends and the like.

ARTICLE V.
NON-PERFORMANCE AND INDEMNIFICATION

5.1 Non-Performance.

(a) If the Company, at any time, shall fail to deliver the shares of Common Stock to the Purchaser required to be delivered pursuant to this Agreement or the Warrants, in accordance with the terms and conditions of this Agreement or the Warrants, as the case may be, for any reason other than the failure of any condition precedent to the Company’s obligations hereunder or the failure by Purchaser to comply with its obligations hereunder, then the Company shall (without limitation to Purchaser’s other remedies at law or in equity):

(i) indemnify and hold Purchaser harmless against any loss, claim or damage (excluding incidental, special, punitive and consequential damages) arising from or as a result of such failure by the Company; and

(ii) reimburse Purchaser for all of its reasonable out-of-pocket expenses, including fees and disbursements of its counsel, incurred by Purchaser in connection with this Agreement, the Warrants and the transactions contemplated herein and therein.

(b) If Purchaser, at any time, shall fail to comply with its obligations to effect the Initial Closing or the Subsequent Closings under this Agreement for any reason other than the failure of any condition precedent to Purchaser’s obligations hereunder or the failure by the Company to comply with its obligations hereunder, then Purchaser shall (without limitation to the Company’s other remedies at law or in equity):

(i) indemnify and hold the Company harmless against any loss, claim or damage (excluding incidental, special, punitive and consequential damages) arising from or as a result of such failure by Purchaser; and

(ii) reimburse the Company for all of its reasonable out-of-pocket expenses, including fees and disbursements of its counsel, incurred by the Company in connection with this Agreement, the Warrants and the transactions contemplated herein and therein.

5.2 Indemnification.

(a) Company Indemnification Obligation. The Company hereby agrees to indemnify the Purchaser and each of its officers, directors, employees, consultants, agents, attorneys, accountants and Affiliates and each Person that controls (within the meaning of Section 20 of the Exchange Act) any of the foregoing Persons (each a “Purchaser Indemnified Party”) against any claim, demand, action, liability, damages (excluding any and all damages other than damages actually suffered by the Purchaser Indemnified Party and excluding incidental, special, punitive and consequential damages), cost or expense (including, without limitation, reasonable legal fees and expenses incurred by such Purchaser Indemnified Party in investigating or defending any such proceeding) (all of the foregoing, including associated costs and expenses being referred to herein as a “Purchaser Indemnified Proceeding”), that it may incur in connection with any of the transactions contemplated hereby arising out of or based upon:

(i) any of the material representations or warranties made by the Company herein being untrue or incorrect at the time such representation or warranty was made; and

(ii) any material breach or non-performance by the Company of any of its covenants, agreements or obligations under this Agreement or the Warrants;

provided, however, that the foregoing indemnity shall not apply to any Purchaser Indemnified Proceeding to the extent that it arises out of, or is based upon, the gross negligence or willful misconduct of the Purchaser in connection therewith or a claim by the Purchaser subject to Section 5.1(a).

(b) Purchaser Indemnification Obligation. Except as otherwise expressly provided in Section 4.2(g), the Purchaser hereby agrees to indemnify the Company and each of its officers, directors, employees, consultants, agents, attorneys, accountants and Affiliates and each Person that controls (within the meaning of Section 20 of the Exchange Act) any of the foregoing Persons (each a “Company Indemnified Party”) against any claim, demand, action, liability, damages (excluding any and all damages other than damages actually suffered by the Company Indemnified Party and excluding incidental, special, punitive and consequential damages), cost or expense (including, without limitation, reasonable legal fees and expenses incurred by such Company Indemnified Party in investigating or defending any such proceeding) (all of the foregoing, including associated costs and expenses being referred to herein as a “Company Indemnified Proceeding,” and together with the Purchaser Indemnified Proceeding, the “Proceeding”), that it may incur in connection with any of the transactions contemplated hereby arising out of or based upon:

(i) any of the material representations or warranties made by the Purchaser herein being untrue or incorrect at the time such representation or warranty was made; and

(ii) any material breach or non-performance by the Purchaser of any of its covenants, agreements or obligations under this Agreement or the Warrants;

provided, however, that the foregoing indemnity shall not apply to any Company Indemnified Proceeding to the extent that it arises out of, or is based upon, the gross negligence or willful misconduct of the Company in connection therewith or a claim by the Company subject to Section 5.1(b).

(c) Conduct of Claims.

(i) Whenever a claim for indemnification shall arise under this Section 5.2, the party seeking indemnification (the “Indemnified Party”), shall notify the party from whom such indemnification is sought (the “Indemnifying Party”) in writing of the Proceeding and the facts constituting the basis for such claim in reasonable detail;

(ii) If any action shall be brought against the Indemnified Party in respect of which indemnity may be sought, the Indemnifying Party shall have the right to assume the defense thereof. The Indemnified Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the Indemnified Party except to the extent that (i) the employment thereof and the Indemnifying Party’s payment of such fees and expenses has been specifically authorized by the Indemnifying Party in writing; or (ii) the Indemnifying Party has failed after a reasonable period of time to assume such defense and to employ counsel. In no event shall the Indemnifying Party be liable for fees and expenses of more than one counsel separate from its own counsel for all Indemnified Parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances; and

(iii) No Indemnifying Party shall, without the prior written consent of the Indemnified Parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification could be sought under this Section 5.2 unless such settlement, compromise or consent (A) includes an unconditional release of each Indemnified Party from all liability arising out of such litigation, investigation, proceeding or claim and (B) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any Indemnified Party.

ARTICLE VI.
MISCELLANEOUS

6.3 Entire Agreement. The Transaction Documents (including the exhibits and schedules thereto), together with the Settlement Agreement, contain the entire understanding of the parties with respect to the subject matter hereof and thereof and supersede all prior agreements and understandings, oral or written, with respect to such matters, which the parties acknowledge have been merged into such documents, exhibits and schedules.

6.5 Amendments; Waivers. No provision of this Agreement may be waived or amended except in a written instrument signed, in the case of an amendment, by the Company and the Purchaser or, in the case of a waiver, by the party against whom enforcement of any such waived provision is sought. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right.

6.6 Headings. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.

6.7 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted assigns. Neither the Company nor the Purchaser may assign this Agreement or any rights or obligations hereunder without the prior written consent of the other party (other than by merger or otherwise by operation of law); provided, however, that the Purchaser may assign its rights and obligations under this Agreement in whole or in part to any of its Affiliates to which it transfers shares of Common Stock or rights to acquire shares pursuant to Section 2.1(b), as long as such Affiliate assignee expressly assumes the obligations hereunder in writing. Notwithstanding any assignment by the Purchaser of its rights and obligations under this Agreement in whole or in part to any of its Affiliates, the Purchaser shall remain jointly and severally liable under this Agreement with such Affiliate assignee, unless expressly released by the Company. No Person acquiring Common Stock from the Purchaser pursuant to a public market purchase or otherwise will thereby obtain any of the rights contained in this Agreement.

Each of the parties hereto hereby waives any objection to any proceeding in such courts whether on the grounds of venue, residence or domicile or on the ground that the proceeding has been brought in an inconvenient forum.

6.11 Survival. The representations and warranties contained herein shall survive the Initial Closing, regardless of any investigation made by or on behalf of the other party to this Agreement or any officer, director or employee of, or Person controlling or under common control with, such party and will survive delivery of and payment for any shares of Common Stock issuable hereunder.

6.12 Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” or “.tif” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” or “.tif” signature page were an original thereof.

6.13 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

6.14 Saturdays, Sundays, Holidays. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then such action may be taken or such right may be exercised on the next succeeding Business Day.

6.15 Construction. The parties agree that each of them and/or their respective counsel has reviewed and had an opportunity to revise the Transaction Documents and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of the Transaction Documents or any amendments hereto.

6.16 Delivery of Shares. Unless otherwise mutually agreed upon by the parties, to the extent reasonably practicable, the Company shall deliver the shares of Common Stock issued to the Purchaser in the Initial Closing and the shares of Common Stock, if any, issued to the Purchaser in a Subsequent Closing to Purchaser’s account via The Depository Trust Company’s Deposit/Withdrawal at Custodian (DWAC) system using the account information provided by Purchaser on or before the applicable Closing Date.

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

THIS WARRANT IS SUBJECT TO RESTRICTIONS ON TRANSFER SET FORTH IN
THIS COMMON STOCK PURCHASE WARRANT.

SYNTROLEUM CORPORATION

COMMON STOCK PURCHASE WARRANT

[DATE]

This Warrant (the “Warrant”) entitles Fletcher International, Ltd., a company domiciled in Bermuda (including any successors or assigns, the “Holder”), for value received, to purchase from SYNTROLEUM CORPORATION, a Delaware corporation (the “Company”), during the Warrant Term (as defined below) and subject to the terms and conditions set forth herein, all or any portion of the Warrant Shares (as defined below) at the Exercise Price (as defined below). This Warrant is issued subject to the following terms and conditions:

1. Warrants.

1.1 General. This Warrant has been issued pursuant to that certain Securities Purchase Agreement, dated October 14, 2009, as it may be amended from time to time, by and among the Company and the Holder (the “Securities Purchase Agreement”), and are subject to the terms and conditions thereof. Unless otherwise defined herein, capitalized terms used herein shall have the meanings set forth in the Securities Purchase Agreement. A copy of the Securities Purchase Agreement may be obtained at no cost by the Holder upon written request to the Secretary of the Company at the principal executive offices of the Company.

1.2 Warrant Amount. This Warrant shall entitle the Holder to purchase up to [                    ] shares of newly-issued Common Stock (the “Warrant Shares”).

1.3 Exercise Price. The per share exercise price for the Warrant Shares shall be [                    ] (the “Exercise Price”).

1.4 Warrant Term. Subject to the limitations contained herein, the Warrant may be exercised (in whole or in part) at any time or from time to time after the date hereof until 11:59 P.M., New York City time on the date that is six (6) years after the date hereof (the “Warrant Term”); provided, however, that in connection with a Change of Control (as defined in the Securities Purchase Agreement), this Warrant shall be subject to Section 3.4.

2. Exercise of Warrant.

2.1 Method of Exercise; Payment. Subject to all of the terms and conditions hereof and the limitations set forth in Sections 2.6 and 2.7, the Holder shall notify the Company prior to any exercise of this Warrant, in whole or in part, with respect to any Warrant Shares, during the Warrant Term, by delivering a notice of intent to exercise substantially in the form attached hereto, three (3) Business Days prior to the exercise date set forth therein; provided that any such notice must be delivered to the Company at least three (3) Business Days prior to the expiration of the Warrant Term. Upon the exercise date set forth in the applicable notice, subject to all of the terms and conditions hereof and the limitations set forth in Sections 2.6 and 2.7, the Holder shall (1) surrender this Warrant to the Company at its principal office, (2) deliver to the Company a subscription substantially in the form attached hereto, and (3) send a (a) wire transfer of immediately available funds or (b) certified or official bank check payable to the order of the Company, in each case in the amount obtained by multiplying (i) the number of Warrant Shares for which the Warrant is being exercised, as designated in such notice and subscription, by (ii) the Exercise Price. Thereupon, the Holder shall be entitled to receive the applicable number of duly authorized, validly issued, fully paid and nonassessable Warrant Shares. Notwithstanding the foregoing, each exercise of the Warrant by the Holder must be for at least 1,000,000 Warrant Shares; provided, however, that the Warrant may be exercised for a lower number of Warrant Shares if such exercise is for all remaining Warrant Shares subject to the Warrant.

2.2 Delivery of Stock Certificates on Exercise. Upon the exercise date of this Warrant, unless otherwise mutually agreed upon by the parties, to the extent reasonably practicable, the Company, at its expense, and in accordance with applicable securities laws, shall deliver the number of Warrant Shares purchased by the Holder on such exercise to Holder’s account via The Depository Trust Company’s Deposit/Withdrawal at Custodian (DWAC) system using the account information provided by Holder in its notice of intent to exercise.

2.3 Shares To Be Fully Paid and Nonassessable. All Warrant Shares issued upon the exercise of this Warrant shall be duly authorized, validly issued, fully paid and nonassessable, free of all liens, taxes, charges and other encumbrances or restrictions on sale (other than those set forth herein).

2.4 Payment of Taxes and Expenses. The Company shall pay any recording, filing, stamp or similar tax which may be payable in respect of any transfer involved in the issuance of, and the preparation and, as applicable, the delivery of certificates representing or the delivery via The Depository Trust Company’s Deposit/Withdrawal at Custodian (DWAC) system of, (i) any Warrant Shares purchased upon exercise of this Warrant and/or (ii) new or replacement warrants in the Holder’s name or the name of any transferee of all or any portion of this Warrant.

2.5 Cooperation with Filings. The Company shall assist and cooperate with the Holder if the Holder is required to make any governmental or regulatory filings or obtain any governmental or regulatory approvals prior to or in connection with any exercise of this Warrant (including, without limitation, making any filings required to be made by the Company).

2.6 Limitation on Exercise. This Warrant shall not be exercisable (i) to the extent that, on or immediately after exercise, the representations in Section 3.2(d) of the Securities Purchase Agreement would be untrue, and (ii) unless and until such representations are made and the Tax Covenants, as applicable, are performed.

2.7 Limitation on Exercise by Transferees. In the event this Warrant is transferred in accordance with Section 5, this Warrant shall not be exercisable (i) to the extent that, on or immediately after exercise, the representations in Section 3.2(d) of the Securities Purchase Agreement would be untrue with respect to the person exercising the Warrant and such person’s Tax Affiliates, and (ii) unless and until the person exercising the Warrant makes such representations and performs the Tax Covenants. For purposes of this Section 2.7, references to the Purchaser and its Tax Affiliates in Section 3.2(d) of the Securities Purchase Agreement and in the Tax Covenants shall be treated as referring to the person exercising the Warrant and such person’s Tax Affiliates.

2.8 The provisions of Section 4.2(g) of the Securities Purchase Agreement shall apply hereto, to the extent relevant to the provisions hereof, substituting “Holder” for “Purchaser” therein.

3. Adjustment of Exercise Price and Warrant Shares. The Exercise Price and the number of Warrant Shares shall be subject to adjustment from time to time upon the happening of certain events as described in this Section 3.

3.1 Subdivision or Combination of Stock. If at any time or from time to time after the date hereof, the Company shall subdivide (by way of stock dividend, stock split or otherwise) its outstanding shares of Common Stock, the Exercise Price in effect immediately prior to such subdivision shall be reduced proportionately and the number of Warrant Shares (calculated to the nearest whole share) shall be increased proportionately, and conversely, in the event the outstanding shares of Common Stock shall be combined (whether by stock combination, reverse stock split or otherwise) into a smaller number of shares, the Exercise Price in effect immediately prior to such combination shall be increased proportionately and the number of Warrant Shares (calculated to the nearest whole share) shall be decreased proportionately. The Exercise Price and the number of Warrant Shares, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described in this Section 3.1.

3.2 Adjustment for Stock Dividends. If at any time after the date hereof, the Company shall declare a dividend or make any other distribution upon any class or series of stock of the Company payable in shares of Common Stock, the Exercise Price in effect immediately prior to such declaration or distribution shall be reduced proportionately and the number of Warrant Shares (calculated to the nearest whole share) shall be increased proportionately, to reflect the issuance of any shares of Common Stock, issuable in payment of such dividend or distribution. The Exercise Price and the number of Warrant Shares, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described in this Section 3.2.

3.3 Adjustments for Reclassifications. If the Common Stock issuable upon the exercise of this Warrant shall be changed into the same or a different number of shares of any class(es) or series of stock and/or the right to receive property, whether by reclassification or otherwise (other than an adjustment under Sections 3.1 and 3.2 or a merger, consolidation, or sale of assets provided for under Section 3.4), then and in each such event, the Holder hereof shall have the right thereafter to convert each Warrant Share into the kind and amount of shares of stock and other securities and property receivable upon such reclassification, or other change by holders of the number of shares of Common Stock into which such Warrant Shares would have been convertible immediately prior to such reclassification or change, all subject to successive adjustments thereafter from time to time pursuant to and in accordance with, the provisions of this Section 3.

3.4 Adjustments for Merger or Consolidation.

(a) If during the Warrant Term a Change of Control or plan or proposal with respect thereto is publicly announced or occurs, and the Acquiring Person (as defined in the Securities Purchase Agreement) (or its direct or indirect parent entity) does not have a class of common equity securities listed or admitted for trading on any securities exchange or over-the-counter or other organized market, whether U.S. or not, then this Warrant shall terminate upon the effective date of a Change of Control; provided that between the date such Change of Control is announced and the effective date of the Change of Control, but not thereafter, the Holder shall have the right to submit to the Company an exercise notice (which exercise notice may, at the Holder’s option, specify that the exercise and payment of the Exercise Price shall occur simultaneously with, and be contingent upon, the occurrence of the Change of Control) in accordance with the terms and conditions of this Warrant; provided, however, that so long as the Company has provided the Holder with at least five (5) Business Days (as defined in the Securities Purchase Agreement) advance written notice of the effective date for the Change of Control, the Company shall not be required to postpone such closing date in order to facilitate the closing of the exercise.

(b) If during the Warrant Term a Change of Control or plan or proposal with respect thereto is publicly announced or occurs, and the Acquiring Person (or its direct or indirect parent entity) has a class of common equity securities listed or admitted for trading on any securities exchange or over-the-counter or other organized market, whether U.S. or not, then:

(i) Between the date such Change of Control is announced and the effective date of the Change of Control, the Holder shall have the right to submit to the Company an exercise notice (which exercise notice may, at the Holder’s option, specify that the exercise and payment of the Exercise Price shall occur simultaneously with, and be contingent upon, the occurrence of the Change of Control) in accordance with the terms and conditions of this Warrant; provided, however, that so long as the Company has provided the Holder with at least five (5) Business Days advance written notice of the effective date for the Change of Control, the Company shall not be required to postpone such closing date in order to facilitate the closing of the exercise;

(ii) The Company shall not enter into an agreement with the Acquiring Person resulting in such Change of Control unless such agreement expressly obligates the Acquiring Person to assume all of the Company’s obligations under this Warrant; and

(iii) In the event that any portion of this Warrant remains unexercised upon consummation of the Change of Control, the Holder shall thereafter automatically have equivalent rights with respect to the Acquiring Person, and from and after the effective date of the Change of Control and regardless of whether the Acquiring Person expressly assumes the Company’s obligations:

(A) all references to the Company in this Warrant shall be references to the Acquiring Person,

(B) all references to Common Stock in this Warrant shall be references to the securities for which the Common Stock are exchanged in the Change of Control (or if none, the most widely-held class of common equity securities of the Acquiring Person),

(C) the Exercise Price shall be adjusted, employing the methodology set forth in the example(s) on Annex I hereto, to equal the Exercise Price as in effect immediately prior to the Change of Control multiplied by a fraction, (1) the numerator 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 Change of Control (or if none, the most widely-held class of voting common equity securities of the Acquiring Person), and (2) the denominator of which is the Daily Market Price of the Company, in the case of (1) and (2) determined as of the Business Day immediately preceding and excluding the date on which the Change of Control is consummated. For purposes of this Warrant, “Daily Market Price” has the meaning given in the Securities Purchase Agreement, substituting references to the “Holder” for the “Purchaser,” and

(D) the number of Warrant Shares shall be adjusted, employing the methodology set forth in the example(s) on Annex I hereto, to equal the product of the number of Warrant Shares in effect immediately prior to the Change of Control multiplied by a fraction, (1) the numerator of which is the Daily Market Price of the Company, and (2) 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 Change of Control (or if none, the most widely-held class of voting common equity securities of the Acquiring Person), in the case of (1) and (2) determined as of the Business Day immediately preceding and excluding the date on which the Change of Control is consummated.

3.5 Minimum Adjustment of Exercise Price. If the amount of any adjustment of the Exercise Price required pursuant to this Section 3 would be less than one-tenth (1/10) of one percent (1%) of the Exercise Price in effect at the time such adjustment is otherwise so required to be made, such amount shall be carried forward and adjustment with respect thereto made at the time of and together with any subsequent adjustment which, together with such amount and any other amount or amounts so carried forward, shall aggregate at least one tenth (1/10) of one percent (1%) of such Exercise Price.

3.6 Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of the Exercise Price and number of Warrant Shares pursuant to this Section 3, this Warrant shall, without any action on the part of the Holder, be adjusted in accordance with this Section 3, and the Company, at its expense, promptly shall compute such adjustment or readjustment in accordance with the terms hereof and prepare and furnish to the Holder a certificate setting forth such adjustment or readjustment, showing in detail the facts upon which such adjustment or readjustment is based. The Company will forthwith send a copy of each such certificate to the Holder in accordance with Section 7.4 below.

4. Notices of Record Date. Upon (a) any establishment by the Company of a record date of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution, or right or option to acquire securities of the Company, or any other right, or (b) any capital reorganization, reclassification, recapitalization, merger or consolidation of the Company with or into any other Person, any transfer of all or substantially all the assets of the Company, or any voluntary or involuntary dissolution, liquidation or winding up of the Company, or the sale, in a single transaction, of a majority of the Company’s voting stock (whether newly issued, or from treasury, or previously issued and then outstanding, or any combination thereof), the Company shall mail to the Holder at least ten (10) Business Days, or such longer period as may be required by law, prior to the record date specified therein and at least ten (10) Business Days prior to the date specified in clause (ii) or (iii) hereof, a notice specifying (i) the date established as the record date for the purpose of such dividend, distribution, option or right and a description of such dividend, distribution, option or right, (ii) the date on which any such reorganization, reclassification, transfer, consolidation, merger, dissolution, liquidation or winding up, or sale is expected to become effective and (iii) the date, if any, fixed as to when the holders of record of Common Stock shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such reorganization, reclassification, transfer, consolidation, merger, dissolution, liquidation or winding up. Subject to the other limitations on exercise contained in this Warrant, nothing in this Section 4 shall prohibit the Holder from exercising this Warrant during the ten (10) Business Day period commencing on the date of such notice.

5. Transfer Provisions, etc.

5.1 Limitations on Transfer.

For purposes of this Section 5.1, references to the Purchaser and its Tax Affiliates in Section 3.2(d) and in the Tax Covenants of the Securities Purchase Agreement shall be treated as referring to the transferee and its Tax Affiliates.
