(iii)                               Purchaser understands that the Shares have not been registered under the Securities Act or any applicable state securities laws and, consequently, Purchaser may have to bear the risk of owning the Shares for an indefinite period of time because the Shares may not be transferred unless (x) the resale of the Shares is registered pursuant to an effective registration statement under the Securities Act in accordance with the terms and conditions set forth in Section 4.1 hereof; (y) Purchaser has delivered to the Company an opinion of counsel (in form, substance and scope customary for opinions of counsel in comparable transactions) to the effect that the Shares to be sold or transferred may be sold or transferred pursuant to an exemption from such registration; or (z) the Shares are sold or transferred pursuant to Rule 144.

(iv)                              Purchaser has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in the Shares to be purchased hereunder.

(v)                                 Purchaser is an “accredited investor” as defined in Rule 501(a) of the rules and regulations promulgated under the Securities Act.

(d)                                 Certain Fees.  No broker, finder or investment banker is entitled to any brokerage, finder’s or other fee or commission in connection with the transactions contemplated by this Agreement based on arrangements made by Purchaser.

(e)                                  Legends.  In connection with the issuance and sale of the Shares, Purchaser understands that each of the Shares, whether certificated or in book-entry form, will be endorsed with the following legend:

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER THE SECURITIES LAWS OF CERTAIN STATES.  THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM OR UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED.”

The Company acknowledges and agrees that the representations contained in Section 3.2 shall not modify, amend or affect Purchaser’s right to rely on the Company’s representations and warranties contained in this Agreement or any representations and warranties contained in the

Collaboration Agreement or any other document or instrument executed and/or delivered in connection with this Agreement or the Collaboration Agreement or the consummation of the transactions contemplated hereby.

ARTICLE IV.
REGISTRATION RIGHTS

4.1                               Registration of the Shares.  The Company shall file with the Commission, on or before the date that is 90 days prior to the first anniversary of the Closing Date, a Registration Statement covering the resale of the Shares to the public by Purchaser.  The Company shall use commercially reasonable efforts to cause the Registration Statement covering the Shares to be declared effective by the Commission by the first anniversary of the Closing Date.  The Company shall cause such Registration Statement to remain effective under the Securities Act until all Shares covered by such Registration Statement have been sold or may be sold without volume restrictions pursuant to Rule 144.  The Company shall promptly notify Purchaser of the effectiveness of such Registration Statement after the Company confirms effectiveness with the Commission.  The Company hereby covenants and agrees to use reasonable commercial efforts to maintain its eligibility to make filings with the Commission on Form S-3 until one or more registrations statements covering the resale of all of the Shares shall have been filed with, and declared effective by, the Commission pursuant to the terms and conditions of this Agreement.

4.2                               Registration Covenant.  Purchaser covenants and agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable to it in connection with sales of the Shares pursuant to a Registration Statement.  The Company shall comply in all material respects with all applicable rules and regulations of the Commission applicable to the filing of a Registration Statement.

4.3                               Registration Procedures.

(a)                                 In connection with the filing by the Company of a Registration Statement covering the Shares, the Company shall furnish to Purchaser (i) a copy of the prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act and (ii) such other documents as Purchaser may reasonably request, in order to facilitate the public sale or other disposition of the Shares.

(b)                                 The Company shall use commercially reasonable efforts to register or qualify the Shares covered by a Registration Statement under the securities laws of each state of the United States as Purchaser shall reasonably request; provided, however, that the Company shall not be required in connection with this subsection (b) to qualify as a foreign corporation or execute a general consent to service of process in any jurisdiction.

(c)                                  If the Company has delivered preliminary or final prospectuses to Purchaser and after having done so the prospectus is amended or supplemented to comply with the requirements of the Securities Act, the Company shall promptly notify Purchaser and, if requested by the Company, Purchaser shall immediately cease making offers or sales of the Shares covered by a Registration Statement and return all prospectuses to the Company.  The Company shall promptly provide Purchaser with revised or supplemented

prospectuses and, following receipt of the revised or supplemented prospectuses, Purchaser shall be free to resume making offers and sales of the Shares under such Registration Statement.

(d)                                 The Company shall be entitled to include in a Registration Statement the shares of Common Stock held by other shareholders of the Company, provided such other shares of Common Stock are excluded first from such Registration Statement in order to comply with any applicable laws or request from any governmental entity or Nasdaq, or in the case of an underwritten offering, in order to comply with a cutback request of any underwriter.

(e)                                  The Company shall pay all expenses incurred in connection with the preparation and filing of such Registration Statement pursuant to this Article 4, including all registration and filing fees and printer, legal and accounting fees related thereto but excluding (i) any brokerage fees, selling commissions or underwriting discounts incurred by Purchaser in connection with sales under any Registration Statement covering the Shares and (ii) the fees and expenses of counsel retained by Purchaser.

(f)                                   The Company shall use commercially reasonable efforts to avoid the issuance of any order suspending the effectiveness of a Registration Statement, or any suspension of the qualifications (or exemption from qualification) of any of the Shares covered by a Registration Statement for sale in any jurisdiction.  The Company shall advise Purchaser promptly after it shall receive notice of any stop order or issuance of any order by the Commission delaying or suspending the effectiveness of a Registration Statement covering the Shares or of the initiation of any proceeding for that purpose, and it will promptly use commercially reasonable efforts to prevent the issuance of any stop order or to obtain its withdrawal at the earliest possible moment if such stop order should be issued.

4.4                               Registration Confidentiality.  Purchaser agrees to treat as confidential (unless otherwise publicly disclosed by the Company or a third party not to the knowledge of Purchaser in breach of an agreement of confidentiality with the Company) any written notice from the Company regarding the Company’s plans to file a Registration Statement and shall not disclose such information to any other person, or use such information, except as is necessary to exercise its rights under this Agreement.

4.5                               Indemnification.

(a)                                 The Company agrees to indemnify and hold harmless Purchaser and each other person, if any, who controls Purchaser within the meaning of the Securities Act or Exchange Act from and against any losses, claims, damages or liabilities to which Purchaser or controlling person may become subject (under the Securities Act, the Exchange Act, state securities or “Blue Sky” laws or otherwise) insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon any untrue statement of a material fact contained in any Registration Statement covering the Shares or in any preliminary prospectus or final prospectus contained in such Registration Statement, or any amendment or supplement to such

Registration Statement, or the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and the Company will reimburse Purchaser or controlling person for any reasonable legal or other expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim, or preparing to defend any such action, proceeding or claim; provided, however, that the Company shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of, or is based upon, an untrue statement made in such Registration Statement, preliminary prospectus or prospectus, or any amendment or supplement in reliance upon and in conformity with written information furnished to the Company by or on behalf of Purchaser or controlling person specifically for use in the preparation thereof or any statement or omission in any prospectus that is corrected in any subsequent prospectus that was delivered to Purchaser prior to the pertinent sale or sales by Purchaser.

(b)                                 Purchaser agrees to indemnify and hold harmless the Company and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, each officer of the Company who signs the Registration Statement and each director of the Company, from and against any losses, claims, damages or liabilities to which the Company or any officer, director or controlling person may become subject (under the Securities Act, the Exchange Act, state securities or “Blue Sky” laws or otherwise), insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon any untrue statement of a material fact contained in any Registration Statement covering the Shares or in any preliminary prospectus, final prospectus contained in such Registration Statement, or any amendment or supplement to such Registration Statement or the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, if such untrue statement or omission was made in reliance upon and in conformity with written information furnished by or on behalf of Purchaser specifically for use in preparation of the Registration Statement, prospectus, amendment or supplement and Purchaser will reimburse the Company, or such officer, director or controlling person, as the case may be, for any legal or other expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim; provided, however, that Purchaser’s obligation to indemnify the Company shall be limited to the Purchase Price.

(c)                                  Promptly after receipt by any indemnified person of a notice of a claim or the beginning of any action in respect of which indemnity is to be sought against an indemnifying person pursuant to this Section 4.5, such indemnified person shall notify the indemnifying person in writing of such claim or of the commencement of such action, but the omission to so notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party under this Section 4.5 (except to the extent that such omission materially and adversely affects the indemnifying party’s ability to defend such action).  Subject to the provisions hereinafter stated, in case any such action shall be brought against an indemnified person, the indemnifying person shall be entitled to participate therein, and, to the extent that it shall elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, shall be entitled to assume the defense thereof, with counsel reasonably satisfactory

to such indemnified person.  After notice from the indemnifying person to such indemnified person of its election to assume the defense thereof, such indemnifying person shall not be liable to such indemnified person for any legal expenses subsequently incurred by such indemnified person in connection with the defense thereof; provided, however, that if there exists or shall exist a conflict of interest that would make it inappropriate, in the opinion of counsel to the indemnified person, for the same counsel to represent both the indemnified person and such indemnifying person or any Affiliate or associate thereof, the indemnified person shall be entitled to retain its own counsel at the expense of such indemnifying person; provided, however, that no indemnifying person shall be responsible for the fees and expenses of more than one separate counsel (together with appropriate local counsel) for all indemnified parties.  In no event shall any indemnifying person be liable in respect of any amounts paid in settlement of any action unless the indemnifying person shall have approved the terms of such settlement; provided, however, that such consent shall not be unreasonably withheld.  No indemnifying person shall, without the prior written consent of the indemnified person, effect any settlement of any pending or threatened proceeding in respect of which any indemnified person is or could have been a party and indemnification could have been sought hereunder by such indemnified person, unless such settlement includes an unconditional release of such indemnified person from all liability on claims that are the subject matter of such proceeding.

(d)                                 If the indemnification provided for in this Section 4.5 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and Purchaser on the other hand, in connection with the statements or omissions or other matters which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations.  The relative fault shall be determined by reference to, among other things, in the case of an untrue statement, whether the untrue statement relates to information supplied by the Company on the one hand or Purchaser on the other hand and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement.  The Company and Purchaser agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to above in this subsection (d).  The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim.  Notwithstanding the provisions of this subsection (d), Purchaser shall not be required to contribute any amount in excess of the amount by which the net amount received by Purchaser from the sale of the Shares to which such loss relates exceeds the amount of any damages which Purchaser has otherwise been required to pay by reason of such untrue statement.  No person guilty of fraudulent misrepresentation (within the

meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(e)                                  The rights and obligations of the Company and Purchaser under this Section 4.5 shall survive the termination of this Agreement.

ARTICLE V.
COVENANTS AND ADDITIONAL AGREEMENTS

5.1                               Stock Ownership Governance.

(a)                                 Lock-Up Period.  Excluding any transfers of Shares between Purchaser and any of its Affiliates, during the twelve (12) month period beginning on the Closing Date and ending on the first anniversary thereof (the “Lock-Up Period”), Purchaser shall not, and shall not cause any other holder of the Shares to, without the prior written consent of the Company, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any Shares or enter into a transaction which would have the same effect.

(b)                                 Market Stand-Off Agreement.  During the Lock-Up Period, Purchaser agrees that in connection with any registration of the Company’s securities that, upon the request of the Company or the underwriters managing any underwritten offering of the Company’s securities, Purchaser will not sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any Shares without the prior written consent of the Company or such underwriters, as the case may be, for such period of time within the Lock-Up Period from the effective date of such registration as the Company or the underwriters may specify.

(c)                                  Remedies.  Without prejudice to the rights and remedies otherwise available to the parties, the Company shall be entitled to equitable relief by way of injunction if Purchaser or any other holder of the Shares breaches or threatens to breach any of the provisions of this Section 5.1.

5.2                               Non-Public Information.  Except as contemplated by the Collaboration Agreement, the Company covenants and agrees that neither it, nor any other Person acting on its behalf will provide Purchaser or its agents or counsel with any information that the Company believes constitutes material non-public information, unless prior thereto Purchaser shall have entered into a written agreement with the Company regarding the confidentiality and use of such information.  The Company understands and confirms that Purchaser shall be relying on the foregoing covenant in effecting transactions in securities of the Company.

5.3                               Use of Proceeds.  The Company shall use the net proceeds from the sale of the Shares hereunder for working capital purposes and shall not use such proceeds: (a) for the redemption of any Common Stock or Common Stock Equivalents, (b) for the settlement of any outstanding litigation or (c) in violation of FCPA or regulations of the Office of Foreign Assets Control of the U.S. Treasury Department.

5.4                               Listing of Common Stock, No Integrated Offerings. The Company shall take no action designed to, or which to the knowledge of the Company is likely to have the effect of,

terminating the registration of the Common Stock under the Exchange Act.  The Company hereby agrees to use commercially reasonable efforts to maintain the listing of the Common Stock, including the Shares, on Nasdaq.  The Company further agrees, if the Company applies to have the Common Stock traded on any other trading market, it will include in such application all of the Shares, and will take such other action as is necessary to cause all of the Shares to be listed on such other trading market as promptly as possible.  The Company will take all action reasonably necessary to continue the listing and trading of its Common Stock, including the Shares, on Nasdaq and will comply in all material respects with the Company’s reporting, filing and other obligations under the bylaws or rules of Nasdaq.  The Company has taken no action designed to, or which to its knowledge is likely to have the effect of, terminating the registration of the Common Stock under the Exchange Act or delisting the Common Stock from the Nasdaq National Market nor has the Company received in the past twelve (12) months any notification that the Commission or the NASD is contemplating terminating such registration or listing. The Company currently meets the continuing eligibility requirements for listing on Nasdaq. The Company has not, and to its knowledge no one acting on its behalf has, (i) taken, directly or indirectly, any action designed to cause or to result in the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of any of the Shares, (ii) sold, bid for, purchased, or paid any compensation for soliciting purchases of, any of the Shares, or (iii) paid or agreed to pay to any Person any compensation for soliciting another to purchase any other securities of the Company. The Company agrees to file with the Commission in a timely manner all reports and other filings required of the Company under the Securities Act and the Exchange Act.  The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Shares in a manner that would require the registration under the Securities Act of the sale of the Shares to the Purchaser or that would be integrated with the offer or sale of the Shares for purposes of the rules and regulations of Nasdaq.

5.5                               Notification under the HSR Act.  Both Parties shall promptly file (and, in any event, within seven (7) Business Days after the date hereof) the HSR Filings with the FTC and the DOJ pursuant to the HSR Act. The Parties shall use their commercially reasonable efforts to promptly obtain HSR Clearance for the consummation of this Agreement and the Collaboration Agreement and the transactions contemplated hereby and thereby and shall keep each other apprised of the status of any communications with, and any inquiries or requests for additional information from, the FTC and the DOJ and shall comply promptly with any such inquiry or request; provided, however, that neither Party shall be required to consent to the divestiture or other disposition of any assets (including the assets of any Affiliate of either Party) or to consent to any other structural or conduct remedy, and each Party and its Affiliates shall have no obligation to contest or settle, administratively or in court, any ruling, order or other action of the FTC or DOJ or any Third Party respecting the transactions contemplated by this Agreement or the Collaboration Agreement. The Parties shall instruct their respective counsel to cooperate with each other and use their commercially reasonable efforts to facilitate and expedite the identification and resolution of any such issues and, consequently, the expiration of the applicable HSR Act waiting period.  Each Party’s counsel will undertake (i) to keep each other appropriately informed of communications from and to personnel of the reviewing antitrust authority, and (ii) to confer with each other regarding appropriate contacts with and responses to personnel of the FTC or DOJ.  Purchaser shall be responsible for any filing fees in connection with the HSR Filings.

6.15        Remedies.  In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, Purchaser and the Company will be entitled to specific performance under this Agreement.  The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in this Agreement and hereby agree to waive and not to assert in any action for specific performance of any such obligation the defense that a remedy at law would be adequate.

Exhibit A

Form of Opinion of Company Counsel

Exhibit A

                 , 2015

Incyte Corporation

1801 Augustine Cut-Off

Wilmington, Delaware 19803

Ladies and Gentlemen:

This opinion letter is furnished to you pursuant to Section 2.3(c) of the Stock Purchase Agreement, dated January 9, 2015 (the “Purchase Agreement”), between Incyte Corporation, a Delaware corporation (“you”), and Agenus Inc., a Delaware corporation (the “Company”), in connection with the offer and sale to you of an aggregate of 7,763,968 shares (the “Shares”) of Common Stock, $0.01 par value per share (the “Common Stock”).

We have acted as counsel to the Company in connection with the offer and sale of the Shares.  For purposes of the following opinions, we have examined the Purchase Agreement and have made such examination of law as we have deemed necessary or appropriate. In our examination of documents, we have assumed the authenticity of all documents submitted to us as originals and the conformity to original documents of all documents submitted to us as conformed or copies, the genuineness of all signatures, the legal capacity of all natural persons, and the completeness and accuracy of the corporate records and stock books of the Company provided to us.

Insofar as the opinions hereinafter expressed in this opinion letter relate to factual matters, we have relied, with your permission, upon certificates, statements and representations of officers and other representatives of the Company, certificates of public officials and representations made in the Purchase Agreement.  For purposes of this opinion letter, we have assumed that all such statements and representations are also true as of the date hereof.

We direct your attention to the fact that our opinions are limited in scope consistent with the Legal Opinion Principles issued by the Committee on Legal Opinions of the American Bar Association’s Business Law Section as published in 53 Business Lawyer 831 (May, 1998).

Our opinion set forth in paragraph 1 below as to the valid existence and good standing of the Company in the State of Delaware is based solely upon a certificate dated January 6, 2015 from the Secretary of State of the State of Delaware, and such opinion is, accordingly, rendered as of the date of such certificate.  Our opinion set forth in paragraph 1 below as to the good standing of the Company and qualification of the Company to conduct business in the Commonwealth of Massachusetts is based solely upon a certificate dated January 5, 2015 from the Secretary of the Commonwealth of the Commonwealth of Massachusetts, and such opinion is, accordingly, rendered as of the date of such certificate.  Finally, our opinion set forth in

paragraph 1 that each of the subsidiaries of the Company is a corporation validly existing under the laws of its state of organization is based solely upon a certificate of an officer of the Company.

We express no opinion herein as to the applicability or effect of the laws of any state or jurisdiction other than the laws of the Commonwealth of Massachusetts, the Delaware General Corporation Law and the federal law of the United States of America that, in our experience, are applicable to transactions of the type contemplated in the Purchase Agreement.  We express no opinion with respect to the effect of the laws of any other jurisdiction on the transactions contemplated by the Purchase Agreement. We note that the Purchase Agreement provides that it shall be governed by and construed in accordance with the internal laws of the State of Delaware and that we are not rendering any opinion herein with respect to Delaware law (except as otherwise stated above).  Therefore, we are rendering our opinions herein as to the Purchase Agreement in the event a court determines that the substantive law of Massachusetts, rather than Delaware, should be applied (as to which application of law we express no opinion).  We express no opinion as to the application of or compliance with the securities and Blue Sky laws of any state, the by-laws and rules of the Financial Industry Regulatory Authority, Inc. or the rules of the Nasdaq Capital Market in connection with the transactions contemplated by the Purchase Agreement.

Our opinion that the Purchase Agreement is enforceable against the Company in accordance with its terms is qualified to the extent that enforcement of the rights and remedies created thereby is subject to bankruptcy and similar laws of general applicability affecting the rights and remedies of the contracting parties, and to the extent that the availability of the remedy of specific performance or of injunctive relief is subject to the discretion of the court before which any proceeding therefor may be brought.

Based upon and subject to the foregoing and to the last paragraph of this opinion letter, we are of the opinion that:

1.                                      The Company is a corporation validly existing and in corporate good standing under the laws of the State of Delaware.  The Company has all requisite corporate power to own and operate its properties and assets and to carry on its business as now conducted (all as described in the Company’s Annual Report on Form 10-K for its fiscal year ended December 31, 2013). The Company is duly qualified to transact business and is in good standing in the Commonwealth of Massachusetts.  Each of the subsidiaries of the Company is a corporation validly existing under the laws of its state of organization.

2.                                      The Company has all requisite power and authority to (i) execute, deliver and perform the Purchase Agreement, (ii) to issue, sell and deliver the Shares pursuant to the Purchase Agreement, and (iii) to carry out and perform its obligations under, and to consummate the transactions contemplated by, the Purchase Agreement.

3.                                      All action on the part of the Company, its directors and its stockholders necessary for the authorization, execution and delivery by the Company of the Purchase

Agreement and the authorization, issuance, sale and delivery of the Shares pursuant to the Purchase Agreement has been duly taken.  The Purchase Agreement has been duly and validly executed and delivered by the Company and constitutes the legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms.

4.                                      The Shares have been duly authorized and, assuming payment therefor in accordance with the Purchase Agreement, are validly issued, fully paid and nonassessable, are free of preemptive or similar rights, and have been issued in compliance with applicable securities laws, rules and regulations.  The rights, privileges and preferences of the Common Stock are as stated in the Company’s Amended and Restated Certificate of Incorporation, as amended to date (the “Corporate Charter”).

5.                                      Assuming the accuracy of, all the representations made by you in the Purchase Agreement, the Company has complied with, or is exempt from, all registration requirements of applicable federal securities laws in connection with the issuance and sale of the Shares.

6.                                      The execution, delivery and performance by the Company of, and the compliance by the Company with the terms of, the Purchase Agreement and the issuance, sale and delivery of the Shares pursuant to the Purchase Agreement do not (a) conflict with or result in a violation of any provision of law, rule or regulation or any rule or regulation applicable to the Company or its subsidiaries or of the Corporate Charter or by-laws of the Company, (b) conflict with, result in a breach of or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or result in or permit the termination or modification of, any agreement, instrument, order, writ, judgment or decree known to us to which the Company of its subsidiaries is a party or is subject or (c) result in the creation or imposition of any lien, claim or encumbrance on any of the assets or properties of the Company or its subsidiaries.

7.                                      In connection with the valid execution, delivery and performance by the Company of the Purchase Agreement, or the offer, sale, issuance or delivery of the Shares, no consent, license, permit, waiver, approval or authorization of, or designation, declaration, registration or filing with, any court, governmental or regulatory authority, or self-regulatory organization, is required which has not been made or obtained.

Except as specifically stated herein, we render no opinion on matters relating to the Purchase Agreement or the transactions contemplated thereby.  This opinion letter is given and speaks only as of the date hereof and is limited to our knowledge of the facts and the laws, statutes, rules and regulations, and judicial and administrative interpretations thereof, as currently in effect, and assumes no event will take place in the future which will affect the opinions set forth herein.  These are all subject to change, possibly with retroactive effect.  We assume no obligation to advise you of changes of any kind that may hereafter be brought to our attention,

even if such changes would affect our opinion, or to update or supplement this opinion letter after the date hereof.  This opinion letter is furnished to you solely and is solely for your benefit.  This opinion letter is not to be made available to or relied upon by any other persons, firms or entities without our prior written consent.  This opinion letter may not be copied, used, quoted, disseminated or circulated in whole or in part.
