Except as the GCL may otherwise require, in the interim between annual meetings of stockholders or special meetings of stockholders called for the election of directors and/or the removal of one or more directors and the filling of any vacancy in that connection, newly created directorships and any vacancies in the Board, including unfilled vacancies resulting from the removal of directors for cause, may be filled by the vote of a majority of the remaining directors then in office, although less than a quorum (as defined in the Corporation’s By-laws), or by the sole remaining director. All directors shall hold office until the expiration of their respective terms of office and until their successors shall have been elected and qualified. A director elected to fill a vacancy resulting from the death, resignation or removal of a director shall serve for the remainder of the full term of the director whose death, resignation or removal shall have created such vacancy and until his successor shall have been elected and qualified.

5.1 Indemnification of Underwriters.

5.1.1 General. Subject to the conditions set forth below, the Company agrees to indemnify and hold harmless each of the Underwriters, and each dealer selected by you that participates in the offer and sale of the Securities (each a “Selected Dealer”) and each of their respective directors, officers and employees and each person, if any, who controls any such Underwriter (“Controlling Person”) within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, against any and all loss, liability, claim, damage and expense whatsoever (including but not limited to any and all legal or other expenses reasonably incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, whether arising out of any action between any of the Underwriters and the Company or between any of the Underwriters and any third party or otherwise) to which they or any of them may become subject under the Act, the Exchange Act or any other statute or at common law or otherwise or under the laws of foreign countries, arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in (i) any Preliminary Prospectus, the Registration Statement, Sale Preliminary Prospectus or the Prospectus (as from time to time each may be amended and supplemented); (ii) any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Securities, including any “road show” or investor presentations made to investors by the Company (whether in person or electronically); (iii) any application or other document or written communication (in this Section 5, collectively called “application”) executed by the Company or based upon written information furnished by the Company in any jurisdiction in order to qualify the Units under the securities laws thereof or filed with the Commission, any state securities commission or agency, NASDAQ or any securities exchange; or (iv) any post effective amendments to the Registration Statement or Prospectus or new Registration Statement or Prospectus filed by the Company with the Commission any state securities commission or agency, NASDAQ or any securities exchange in which is included any of the Representative’s Securities, or the omission or alleged omission from any Preliminary Prospectus, the Registration Statement, Sale Preliminary Prospectus or the Prospectus or subsequent filing by the Company under clause (iv) above of a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, unless such statement or omission

was made in reliance upon and in conformity with written information furnished to the Company with respect to an Underwriter by or on behalf of such Underwriter expressly for use in any Preliminary Prospectus, the Registration Statement, Sale Preliminary Prospectus or Prospectus, or any amendment or supplement thereof, or in any application, as the case may be. With respect to any untrue statement or omission or alleged untrue statement or omission made in the Preliminary Prospectus, the indemnity agreement contained in this paragraph shall not inure to the benefit of any Underwriter to the extent that any loss, liability, claim, damage or expense of such Underwriter results from the fact that a copy of the Prospectus was not given or sent to the person asserting any such loss, liability, claim or damage at or prior to the written confirmation of sale of the Securities to such person as required by the Act and the Regulations, and if the untrue statement or omission has been corrected in the Prospectus, unless such failure to deliver the Prospectus was a result of non-compliance by the Company with its obligations under Section 3.4 hereof. The Company agrees promptly to notify the Representative of the commencement of any litigation or proceedings against the Company or any of its officers, directors or controlling persons in connection with the issue and sale of the Securities or in connection with the Registration Statement, Sale Preliminary Prospectus or Prospectus.

5.1.2 Procedure. If any action is brought against an Underwriter, a Selected Dealer or a controlling person in respect of which indemnity may be sought against the Company pursuant to Section 5.1.1, such Underwriter or Selected Dealer shall promptly notify the Company in writing of the institution of such action and the Company shall assume the defense of such action, including the employment and fees of counsel (subject to the reasonable approval of such Underwriter or Selected Dealer, as the case may be) and payment of actual expenses. Such Underwriter, Selected Dealer or controlling person shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such Underwriter, Selected Dealer or controlling person unless (i) the employment of such counsel at the expense of the Company shall have been authorized in writing by the Company in connection with the defense of such action, or (ii) the Company shall not have employed counsel to have charge of the defense of such action, or (iii) such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to those available to the Company (in which case the Company shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events the reasonable fees and expenses of not more than one additional firm of attorneys selected by the Underwriter, Selected Dealer and/or controlling person shall be borne by the Company. Notwithstanding anything to the contrary contained herein, if the Underwriter, Selected Dealer or controlling person shall assume the defense of such action as provided above, the Company shall have the right to approve the terms of any settlement of such action which approval shall not be unreasonably withheld.

5.2 Indemnification of the Company. Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Company, its directors, officers and employees and agents who control the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any and all loss, liability, claim, damage and expense described in the foregoing indemnity from the Company to the several Underwriters, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions made in any Preliminary Prospectus, the Registration Statement, Sale Preliminary Prospectus or Prospectus or any amendment or supplement thereto or in any application, in reliance upon, and in strict

conformity with, written information furnished to the Company with respect to such Underwriter by or on behalf of the Underwriter expressly for use in such Preliminary Prospectus, the Registration Statement, Sale Preliminary Prospectus or Prospectus or any amendment or supplement thereto or in any such application. In case any action shall be brought against the Company or any other person so indemnified based on any Preliminary Prospectus, the Registration Statement, Sale Preliminary Prospectus or Prospectus or any amendment or supplement thereto or any application, and in respect of which indemnity may be sought against any Underwriter, such Underwriter shall have the rights and duties given to the Company, and the Company and each other person so indemnified shall have the rights and duties given to the several Underwriters by the provisions of Section 5.1.2.

5.3 Contribution.

5.3.1 Contribution Rights. In order to provide for just and equitable contribution under the Act in any case in which (i) any person entitled to indemnification under this Section 5 makes claim for indemnification pursuant hereto but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this Section 5 provides for indemnification in such case, or (ii) contribution under the Act, the Exchange Act or otherwise may be required on the part of any such person in circumstances for which indemnification is provided under this Section 5, then, and in each such case, the Company and the Underwriters shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by said indemnity agreement incurred by the Company and the Underwriters, as incurred, in such proportions that the Underwriters are responsible for that portion represented by the percentage that the underwriting discount appearing on the cover page of the Prospectus bears to the initial offering price appearing thereon and the Company is responsible for the balance; provided, that, no person guilty of a fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Underwriters shall contribute in such proportion as is appropriate to reflect the relative fault of the Company and the Underwriters in connection with the actions or omissions which resulted in such loss, claim, damage, liability or action, as well as any other relevant equitable considerations. The relative fault of the Company and the Underwriters shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. Notwithstanding the provisions of this Section 5.3.1, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Public Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay in respect of such losses, liabilities, claims, damages and expenses. For purposes of this Section, each director, officer and employee of an Underwriter or the Company, as applicable, and each person, if any, who controls an Underwriter or the Company, as applicable, within the meaning of Section 15 of the Act shall have the same rights to contribution as the Underwriters or the Company, as applicable.

5.3.2 Contribution Procedure. Within fifteen days after receipt by any party to this Agreement (or its representative) of notice of the commencement of any action, suit or proceeding, such party will, if a claim for contribution in respect thereof is to be made against another party (“contributing party”), notify the contributing party of the commencement thereof, but the omission to so notify the contributing party will not relieve it from any liability which it may have to any other party other than for contribution hereunder. In case any such action, suit or proceeding is brought against any party, and such party notifies a contributing party or its representative of the commencement thereof within the aforesaid fifteen days, the contributing party will be entitled to participate therein with the notifying party and any other contributing party similarly notified. Any such contributing party shall not be liable to any party seeking contribution on account of any settlement of any claim, action or proceeding effected by such party seeking contribution on account of any settlement of any claim, action or proceeding effected by such party seeking contribution without the written consent of such contributing party. The contribution provisions contained in this Section are intended to supersede, to the extent permitted by law, any right to contribution under the Act, the Exchange Act or otherwise available. The Underwriters’ obligations to contribute pursuant to this Section 5.3 are several and not joint.

6. Default by an Underwriter.

6.1 Default Not Exceeding 10% of Firm Units or Option Units. If any Underwriter or Underwriters shall default in its or their obligations to purchase the Firm Units or the Option Units, if the Over-Allotment Option is exercised, hereunder, and if the number of the Firm Units or Option Units with respect to which such default relates does not exceed in the aggregate 10% of the number of Firm Units or Option Units that all Underwriters have agreed to purchase hereunder, then such Firm Units or Option Units to which the default relates shall be purchased by the non-defaulting Underwriters in proportion to their respective commitments hereunder.

6.2 Default Exceeding 10% of Firm Units or Option Units. In the event that the default addressed in Section 6.1 above relates to more than 10% of the Firm Units or Option Units, you may in your discretion arrange for yourself or for another party or parties to purchase such Firm Units or Option Units to which such default relates on the terms contained herein. If within one Business Day after such default relating to more than 10% of the Firm Units or Option Units you do not arrange for the purchase of such Firm Units or Option Units, then the Company shall be entitled to a further period of one Business Day within which to procure another party or parties satisfactory to you to purchase said Firm Units or Option Units on such terms. In the event that neither you nor the Company arrange for the purchase of the Firm Units or Option Units to which a default relates as provided in this Section 6, this Agreement will be terminated by you or the Company without liability on the part of the Company (except as provided in Sections 3.11.1 and 5 hereof) or the several Underwriters (except as provided in Section 5 hereof); provided, however, that if such default occurs with respect to the Option Units, this Agreement will not terminate as to the Firm Units; and provided further that nothing herein shall relieve a defaulting Underwriter of its liability, if any, to the other several Underwriters and to the Company for damages occasioned by its default hereunder.

6.3 Postponement of Closing Date. In the event that the Firm Units or Option Units to which the default relates are to be purchased by the non-defaulting Underwriters, or are to be purchased by another party or parties as aforesaid, you or the Company shall have the right to postpone the Closing Date or Option Closing Date for a reasonable period, but not in any event exceeding five Business Days, in order to effect whatever changes may thereby be made necessary in the Registration Statement, the Sale Preliminary Prospectus or the Prospectus or in any other documents and arrangements, and the Company agrees to file promptly any amendment to the Registration Statement or the Prospectus that in the opinion of counsel for the Underwriters may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any party substituted under this Section 6 with like effect as if it had originally been a party to this Agreement with respect to such Securities.

7. Right to Appoint Observer. Until the consummation of a Business Combination, upon notice from ▇▇▇▇▇▇ ▇▇▇▇▇▇ & Co. to the Company, ▇▇▇▇▇▇ ▇▇▇▇▇▇ & Co. shall have the right to send a representative (who need not be the same individual from meeting to meeting) to observe each meeting of the Board of Directors of the Company; provided that such representative shall sign a Regulation FD compliant confidentiality agreement which is reasonably acceptable to ▇▇▇▇▇▇ ▇▇▇▇▇▇ & Co. and its counsel in connection with such representative’s attendance at meetings of the Board of Directors; and provided further that upon written notice to ▇▇▇▇▇▇ ▇▇▇▇▇▇ & Co., the Company may exclude the representative from meetings where, in the written opinion of counsel for the Company, the representative’s presence would destroy the attorney-client privilege. The Company agrees to give ▇▇▇▇▇▇ ▇▇▇▇▇▇ & Co. written notice of each such meeting and to provide ▇▇▇▇▇▇ ▇▇▇▇▇▇ & Co. with an agenda and minutes of the meeting no later than it gives such notice and provides such items to the other directors and to reimburse the representative of ▇▇▇▇▇▇ ▇▇▇▇▇▇ & Co. for its reasonable out-of-pocket expenses incurred in connection with its attendance at the meeting, including but not limited to, food, lodging and transportation.

8. Additional Covenants.

8.1 Additional Shares or Options. The Company hereby agrees that until the consummation of a Business Combination, it shall not issue any Common Stock (except with respect to any exercise of Warrants) or any options or other securities convertible into Common Stock, or any shares of preferred stock or other Securities of the Company which participate or may participate in any manner in the Trust Account or which vote as a class with the Common Stock on a Business Combination.

8.2 Insider Letters; Subscription Agreements; Trust Agreement. The Company shall not take any action or omit to take any action which would cause a breach of any of the Insider Letters or the Subscription Agreements and will not allow any amendments to, or waivers of, the Insider Letters, the Subscription Agreement or the Trust Agreement without the prior written consent of the Representative.

8.3 Certificate of Incorporation and Bylaws. The Company shall not take any action or omit to take any action that would cause the Company to be in breach or violation of its Certificate of Incorporation or Bylaws. Prior to the consummation of a Business Combination,

the Company will not amend its Certificate of Incorporation without the prior written consent of the Representative.

8.4 Acquisition/Liquidation Procedure. The Company agrees: (i) prior to the consummation of any Business Combination, it will submit such transaction to the Company’s stockholders for their approval (“Business Combination Vote”) even if the nature of the acquisition is such as would not ordinarily require stockholder approval under the laws of the state of Delaware; and (ii) in the event that the Company does not effect a business combination within twenty-four months from the consummation of the offering (the “Termination Date”), this shall trigger an automatic winding-up of the Company and the trust account will be liquidated to holders of IPO Shares in the manner described in the Sale Preliminary Prospectus and the Prospectus as soon as reasonably practicable, and subject to the requirements of the laws of the state of Delaware. For purposes of this Section 8.4, the term “IPO Shares” means the Common Stock included in the Public Securities.

8.4.1 Upon liquidation of the Trust Account, subject to the requirements of the laws of the State of Delaware, the Company will distribute only to the holders of IPO Shares an aggregate sum equal to the Company’s Liquidation Value, which sum shall be distributed pro rata among the holders of the IPO Shares. The Company’s “Liquidation Value” means: (i) all of the all principal and accrued interest contained within the Trust Account, less any amounts previously distributed to the Company out of the interest earned on the Trust Account pursuant to the terms of the Trust Agreement (after payment of, or provision for, applicable taxes and claims of creditors), plus (ii) all cash and other liquid assets (which shall be reduced to cash as part of the Company’s winding up) then held by the Company outside of the Trust Account, all as distributed in amounts to the holders as determined by CST, as trustee of the Trust Account. Only holders of IPO Shares as of the record date for the distribution shall be entitled to receive liquidating distributions with respect to the IPO Shares they beneficially own and the Company shall pay no liquidating distributions with respect to any other shares of capital stock of the Company, including the shares of Common Stock held by the Existing Stockholders prior to the Offering (but shall include Common Stock purchased by Existing Stockholders after the Offering).

8.4.2 With respect to the Business Combination Vote, the Company shall cause all of the Existing Stockholders to vote (i) the Common Stock owned by them immediately prior to this Offering in accordance with the vote of the holders of a majority of the IPO Shares present, in person or by proxy, at a meeting of the Company’s stockholders called for such purpose and (ii) the shares of Common Stock acquired by them in connection with or following this Offering in favor of any Business Combination, at a meeting of the Company’s Stockholders called for such purpose.

8.4.3 At the time the Company seeks approval of any potential Business Combination (prior to the confirmation of its initial Business Combination), the Company will offer each of the holders of the IPO Shares the right to redeem their IPO Shares into a pro rata share of the Trust Account (the “Conversion Price”). If holders of less than 30% in interest of the Company’s Common Stock vote against such approval of a Business Combination, the Company may, but will not be required to, proceed with such Business Combination. If the Company elects to so proceed, it will redeem shares of Common Stock, based upon the

Conversion Price, from those holders of Common Stock who affirmatively requested such redemption and who voted against the Business Combination as provided under the laws of the State of Delaware. If holders of 30% or more in interest of the Common Stock vote against approval of any potential Business Combination, the Company will not proceed with such Business Combination and will liquidate.

8.5 Rule 419. The Company agrees that it will use its best efforts to prevent the Company from becoming subject to Rule 419 under the Act prior to the consummation of any Business Combination, including but not limited to using its best efforts to prevent any of the Company’s outstanding securities from being deemed to be a “▇▇▇▇▇ stock” as defined in Rule 3a-51-1 under the Exchange Act during such period.

8.6 Affiliated Transactions. Except as disclosed on the Registration Statement, the Company shall cause each of the Existing Stockholders to agree that, in order to minimize potential conflicts of interest which may arise from multiple affiliations, the Existing Stockholders will present to the Company for its consideration, prior to presentation to any other person or company, any suitable opportunity to acquire an operating business, until the earlier of the consummation by the Company of a Business Combination, the liquidation of the Company or until such time as the Existing Stockholders cease to be an officer or director of the Company, subject to any pre-existing fiduciary or contractual obligations the Existing Stockholders might have.

8.7 Target Net Assets. The Company agrees that its initial Business Combination must be with one or more Target Businesses that have an aggregate fair market value equal to at least 80% of the amount in the Company’s Trust Account (less Deferred Fees, including interest thereon, held in the Trust Account) at the time of such Business Combination. The fair market value of each Target Business must be determined by the Board of Directors of the Company based upon standards generally accepted by the financial community, such as actual and potential sales, earnings and cash flow and book value. If the Board of Directors of the Company is not able to independently determine that the Target Business has a fair market value of at least 80% of the Company’s net assets held in trust, net of taxes, at the time of such transaction, or if the target business is affiliated with any of the Existing Stockholders, the Company will obtain an opinion from an unaffiliated, independent investment banking firm which is a member of the NASD with respect to the satisfaction of such criteria. The Company is not required to obtain an opinion from an investment banking firm as to the fair market value if the Company’s Board of Directors independently determines that the Target Business does have sufficient fair market value.

8.8 Trust Account Waiver Acknowledgments. The Company hereby agrees that it will not commence its due diligence investigation of any operating business or businesses which the Company seeks to acquire (each, a “Target Business”) or obtain the services of any vendor unless and until such Target Business or vendor acknowledges in writing, whether through a letter of intent, memorandum of understanding or other similar document (and subsequently acknowledges the same in any definitive document replacing any of the foregoing), that (a) it has read the Prospectus and understands that the Company has established the Trust Account, initially in an amount of $285,075,000 (without giving effect to any exercise of the Over-allotment Option) for the benefit of the public stockholders and that, except for a portion of the

interest earned on the amounts held in the Trust Account, the Company may disburse monies from the Trust Account only: (i) to the public stockholders in the event of the redemption of their shares or the dissolution and liquidation of the Trust Account as part of the Company’s plan of dissolution and liquidation or (ii) to the Company after it consummates a Business Combination and (b) for and in consideration of the Company (1) agreeing to evaluate such target business for purposes of consummating a Business Combination with it or (2) agreeing to engage the services of the vendor, as the case may be, such target business or vendor agrees that it does not have any right, title, interest or claim of any kind in or to any monies of the Trust Account (“claim”) and waives any claim it may have in the future as a result of, or arising out of, any negotiations, contracts or agreements with the Company and will not seek recourse against the Trust Account for any reason whatsoever. The foregoing letters shall substantially be in the form attached hereto as Exhibits A and B, respectively.

8.9 Proxy and Other Information. The Company shall provide counsel to the Representative with ten copies of all proxy information and all related material filed with the commission in connection with a Business Combination concurrently with such filing with the commission. In addition, the Company shall furnish any other state in which its initial public offering was registered, such information as may be requested by such state.

9. Representations and Agreements to Survive Delivery. Except as the context otherwise requires, all representations, warranties and agreements contained in this Agreement shall be deemed to be representations, warranties and agreements as of the Closing Dates and such representations, warranties and agreements of the Underwriters and the Company, including the indemnity agreements contained in Section 5 hereof, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Underwriter, the Company or any controlling person, and shall survive termination of this Agreement or the issuance and delivery of the Securities to the several Underwriters until the earlier of the expiration of any applicable statute of limitations and the seventh anniversary of the later of the Closing Date or the Option Closing Date, if any, at which time the representations, warranties and agreements shall terminate and be of no further force and effect.

10. Effective Date of This Agreement and Termination Thereof.

10.1 Effective Date. This Agreement shall become effective on the Effective Date at the time the Registration Statement is declared effective by the Commission.

10.2 Termination. You shall have the right to terminate this Agreement at any time prior to the Closing Date, (i) if any domestic or international event or act or occurrence has materially disrupted, or in your opinion will in the immediate future materially disrupt, general securities markets in the United States; or (ii) if trading on the New York Stock Exchange, the American Stock Exchange, the NASDAQ Global Market, the NASDAQ Capital Market or on the NASD OTC Bulletin Board (or successor trading market) shall have been suspended, or minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been fixed, or maximum ranges for prices for securities shall have been required on the American Stock Exchange, the NASDAQ Global Market, the NASDAQ Capital Market or on the NASD OTC Bulletin Board (or successor trading market) or by order of the Commission or any other government authority having jurisdiction, or (iii) if the United States

shall have become involved in a new war or an increase in major hostilities, or (iv) if a banking moratorium has been declared by a New York State or federal authority, or (v) if a moratorium on foreign exchange trading has been declared which materially adversely impacts the United States securities market, or (vi) if the Company shall have sustained a material loss by fire, flood, accident, hurricane, earthquake, theft, sabotage or other calamity or malicious act which, whether or not such loss shall have been insured, will, in your opinion, make it inadvisable to proceed with the delivery of the Units, or (vii) if any of the Company’s representations, warranties or covenants hereunder are breached, or (viii) if the Representative shall have become aware after the date hereof of such a material adverse change in the conditions or prospects of the Company, or such adverse material change in general market conditions, including without limitation as a result of terrorist activities after the date hereof, as in the Representative’s judgment would make it impracticable to proceed with the offering, sale and/or delivery of the Units or to enforce contracts made by the Underwriters for the sale of the Securities.

11.4 Entire Agreement. This Agreement (together with the other agreements and documents being delivered pursuant to or in connection with this Agreement) constitute the entire agreement of the parties hereto with respect to the subject matter hereof and thereof, and supersede all prior agreements and understandings of the parties, oral and written, with respect to the subject matter hereof.

11.5 Binding Effect. This Agreement shall inure solely to the benefit of and shall be binding upon the Representative, the Underwriters, the Company and the controlling persons, directors and officers referred to in Section 5 hereof, and their respective successors, legal representatives and assigns, and no other person shall have or be construed to have any legal or equitable right, remedy or claim under or in respect of or by virtue of this Agreement or any provisions herein contained. This agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the parties hereto and said controlling persons and their respective successors, officers, directors, heirs and legal representatives, and it is not for the benefit of any other person. The term “successors and assigns” shall not include a purchaser, in its capacity as such, of securities from any of the Underwriters. The Company acknowledges and agrees that: (i) the sale and issuance of the securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company and the Underwriters; (ii) in connection therewith and with the process leading to the offering, the Underwriters are acting solely as a principal and not the agent or fiduciary of the Company; (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto, including any negotiation related to the pricing of the securities; and (iv) the Company has consulted its own legal and financial advisors to the extent it has deemed appropriate in connection with this Agreement and the offering.

The Underwriters hereby expressly disclaim any fiduciary or similar obligations to the Company, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Company hereby confirms its understanding and agreement to that effect. The Company and the Underwriters agree that they are each responsible for making their own independent judgments with respect to any such transactions, and that any opinions or views expressed by the Underwriters to the Company regarding such transactions, including but not

limited to any opinions or views with respect to the price or market for the Company’s securities, do not constitute advice or recommendations to the Company. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any breach or alleged breach of any fiduciary or similar duty to the Company in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions.

APPENDIX A

1. The Company has been duly organized and is validly existing as a corporation and is in good standing under the laws of its place of incorporation. The Company is duly qualified and licensed and in good standing as a foreign corporation in each jurisdiction in which its ownership or leasing of any properties or the character of its operations requires such qualification or licensing, except where the failure to qualify would not have a material adverse effect on the assets, business or operations of the Company.

2. All issued and outstanding securities of the Company (including, without limitation, the Placement Warrants) have been duly authorized and validly issued and are fully paid and non-assessable; the holders thereof are not subject to personal liability by reason of being such holders; and none of such securities were issued in violation of the preemptive rights of any stockholder of the Company arising by operation of law or under the Amended and Restated Certificate of Incorporation (“Certificate”) or Bylaws of the Company. The offers and sales of the outstanding Common Stock prior to the Offering were at all relevant times either registered under the Act or exempt from such registration requirements. The authorized and, to such counsel’s knowledge, outstanding capital stock of the Company is as set forth in the Prospectus.

3. The Securities have been duly authorized and, when issued and paid for, will be validly issued, fully paid and non-assessable; the holders thereof are not and will not be subject to personal liability by reason of being such holders. The Securities are not and will not be subject to the preemptive rights of any holders of any security of the Company arising by operation of law or under the Articles of the Company. When issued, the Representative’s Purchase Option, the Representative’s Warrants and the Warrants will constitute valid and binding obligations of the Company to issue and sell, upon exercise thereof and payment therefor, the number and type of securities of the Company called for thereby and such Warrants, the Representative’s Purchase Option, and the Representative’s Warrants, when issued, in each case, are enforceable against the Company in accordance with their respective terms, except (a) as such enforceability may be limited by bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally, (b) as enforceability of any indemnification or contribution provision may be limited under the federal and state securities laws, and (c) that the remedy of specific performance and injunctive and other forms of equitable relief may be subject to the equitable defenses and to the discretion of the court before which any proceeding therefor may be brought. The certificates representing the Securities are in due and proper form.

4. The Placement Warrants constitute valid and binding obligations of the Company to issue and sell, upon exercise thereof and payment therefor, the number and type of securities of the Company called for thereby, and such Placement Warrants are enforceable against the Company in accordance with their respective terms, except: (i) as such enforceability may be limited by bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally; (ii) as enforceability of any indemnification or contribution provision may be limited under federal and state securities laws; and (iii) that the remedy of specific performance and injunctive and other forms of equitable relief may be subject to the equitable defenses and to the discretion of the court before which any proceeding therefor may be brought. A sufficient number of shares of Common Stock have been reserved for issuance upon exercise of the Placement Warrants. The Common Stock underlying the Placement Warrants will, upon exercise of the Warrants and payment of the exercise price thereof, be duly and validly issued, fully paid and non-assessable and will not have been issued in violation of or subject to preemptive or, to such counsel’s knowledge, similar rights that entitle or will entitle any person to acquire any securities from the Company upon issuance thereof.

5. This Agreement, the Warrant Agreement, the Services Agreement, the Trust Agreement, the Escrow Agreement and the Subscription Agreements have each been duly and validly authorized and, when executed and delivered by the Company, constitute, and the Representative’s Purchase Option has been duly and validly authorized by the Company and, when executed and delivered, will constitute, the valid and binding obligations of the Company, enforceable against the Company in accordance with their respective terms, except (a) as such enforceability may be limited by bankruptcy,

insolvency, reorganization or similar laws affecting creditors’ rights generally, (b) as enforceability of any indemnification or contribution provisions may be limited under the federal and state securities laws, and (c) that the remedy of specific performance and injunctive and other forms of equitable relief may be subject to the equitable defenses and to the discretion of the court before which any proceeding therefor may be brought.

6. The execution, delivery and performance of this Agreement, the Warrant Agreement, the Representative’s Purchase Option, the Escrow Agreement, the Trust Agreement, the Services Agreement and the Subscription Agreements and compliance by the Company with the terms and provisions thereof and the consummation of the transactions contemplated thereby, and the issuance and sale of the Securities, do not and will not, with or without the giving of notice or the lapse of time, or both, (a) to such counsel’s knowledge, conflict with, or result in a breach of, any of the terms or provisions of, or constitute a default under, or result in the creation or modification of any lien, security interest, charge or encumbrance upon any of the properties or assets of the Company pursuant to the terms of, any mortgage, deed of trust, note, indenture, loan, contract, commitment or other agreement or instrument filed as an exhibit to the Registration Statement, (b) result in any violation of the provisions of the Certificate of Incorporation or the Bylaws of the Company, or (c) to such counsel’s knowledge, violate any United States statute or any judgment, order or decree, rule or regulation applicable to the Company of any court, United States federal, state or other regulatory authority or other governmental body having jurisdiction over the Company, its properties or assets.

7. The Registration Statement, the Sale Preliminary Prospectus and the Prospectus and any post-effective amendments or supplements thereto (other than the financial statements included therein, as to which no opinion need be rendered) each as of their respective dates appeared on their face to comply as to form in all material respects with the requirements of the Act and Regulations. The Securities and all other securities issued or issuable by the Company conform in all material respects to the description thereof contained in the Registration Statement and the Prospectus. The descriptions in the Registration Statement, the Sale Preliminary Prospectus and in the Prospectus, insofar as such statements constitute a summary of statutes, legal matters, contracts, documents or proceedings referred to therein, fairly present in all material respects the information required to be shown with respect to such statutes, legal matters, contracts, documents and proceedings, and such counsel does not know of any statutes or legal or governmental proceedings required to be described in the Sale Preliminary Prospectus and the Prospectus that are not described in the Registration Statement, the Sale Preliminary Prospectus or the Prospectus or included as exhibits to the Registration Statement that are not described or included as required.

8. The Registration Statement is effective under the Act. To such counsel’s knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are pending or threatened under the Act or applicable state securities laws.

9. To such counsel’s knowledge, there is no action, suit or proceeding before or by any court of governmental agency or body, domestic or foreign, now pending, or threatened against the Company that is required to be described in the Registration Statement.

The opinion of counsel shall further include a statement to the effect that such counsel has participated in conferences with officers and other representatives of the Company, the Underwriters and the independent registered public accounting firm of the Company, at which conferences the contents of the Registration Statement, the Sale Preliminary Prospectus and the Prospectus contained therein and related matters were discussed and, although such counsel is not passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Sale Preliminary Prospectus and the Prospectus contained therein (except as otherwise set forth in the foregoing opinion), solely on the basis of the foregoing without independent check and verification, no facts have come to the attention of such counsel which lead them to believe that the Registration Statement or any amendment thereto, at the time the Registration Statement or amendment became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading or the Prospectus or any amendment or

supplement thereto, at the time they were filed pursuant to Rule 424(b) or at the date of such counsel’s opinion, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statement therein, in light of the circumstances under which they were made, not misleading (except that such counsel need express no opinion with respect to the financial information and statistical data and information included in the Registration Statement, the Sale Preliminary Prospectus or the Prospectus).
