SECTION 5.  Indemnification.
 
SECTION 6.  Indemnification of Placement Agents. The Company agrees to indemnify and hold harmless the each Placement Agent, its affiliates, as such term is defined in Rule 501(b) under the Act (each, an “Affiliate”), its employees and agents and each person, if any, who controls any Placement Agent within the meaning of Section 15 of the Act or Section 20 of the Exchange Act as follows:
 
(i)  against any and all loss, liability, claim, damage and expense whatsoever arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in the General Disclosure Package, any Issuer-Represented Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;
 
(ii)  against any and all loss, liability, claim, damage and expense whatsoever to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company; and
 
(iii)  against any and all expense whatsoever (including the fees and disbursements of counsel chosen by the Placement Agents), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;
 
provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Placement Agent through the Representative expressly for use in the Registration Statement (or any amendment thereto), any Issuer-Represented Free Writing Prospectus or the Prospectus.
 
(b)  Indemnification of Company, Director, Officers, Agents and Employees. Each Placement Agent severally agrees to indemnify and hold harmless the Company, its directors, each of its officers, agents and employees, and each person, if any, who controls 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 indemnity contained in subsection (a) of this Section, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), or any Issuer-Represented Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by such Placement Agent through the Representative expressly for use in the Registration Statement (or any amendment thereto) or the Prospectus (or any amendment or supplement thereto).
 
(c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) above, the Company shall be entitled to assume the defense of any action or proceeding with counsel reasonably satisfactory to the indemnified party. Upon assumption by the Company of the defense of any such action or proceeding, the indemnified party shall have the right to participate in such action or proceeding and to retain its own counsel but the Company shall not be liable for any legal expenses of such counsel retained by such indemnified party in connection with the defense thereof unless (i) the Company has agreed to pay such fees and expenses, (ii) the Company shall have failed to employ counsel reasonably satisfactory to the indemnified party in a timely manner, or (iii) the indemnified party shall have been advised by counsel that there are actual or potential conflicting interests between the Company and the indemnified party, including situations in which there are one or more legal defenses available to the indemnified party that are different from or additional to those available to the Company; provided, however, that the Company shall not, in connection with any one such action or proceeding or separate but substantially similar actions or proceedings in the same jurisdiction arising out of the same general allegations, be liable for the fees and expenses of more than one separate firm of attorneys at any time for all indemnified parties. The Company will not settle, compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding in respect of which indemnification could be sought under this Section 6 or 7 (whether or not any indemnified party is an actual or potential party to such claim, action or proceeding), unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action or proceeding. The Company shall not have any liability with respect to any settlement, compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding entered into or made by any indemnified party in respect of which indemnification or contribution could be sought under this Section 6 or 7 (whether or not the any indemnified party is an actual or potential party to such claim, action or proceeding), without the prior written consent of the Company.
 
(d) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 90 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 45 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement, unless there is a bona fide dispute between such indemnifying party and indemnified party regarding such reimbursement of such fees and expenses and the indemnifying party shall have fully reimbursed the indemnified party for all undisputed fees and expenses.
 
(e) Placement Agents’ Information. The parties hereto acknowledge and agree that the statements set forth in the second sentence of the third paragraph and the seventh and eighth paragraphs under the heading “Plan of Distribution” in the Prospectus Supplement constitute the only written information relating to any Placement Agent furnished to the Company by any Placement Agent through the Representative expressly for use in the Registration Statement (or any amendment thereto), Prospectus (or any amendment or supplement thereto) and the General Disclosure Package, including for purposes of Sections 2(a)(i), 6(a) and 6(b) hereof.
 
SECTION 7.  Contribution.
 
SECTION 8.  If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Placement Agents, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Placement Agents on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.
 
The relative benefits received by the Company on the one hand and the Placement Agents on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as (x) the net proceeds from the offering of the Securities pursuant to this Agreement received by the Company and (y) the total fees received by the Placement Agents pursuant to Section 1(b) hereof bear to the sum of (x) and (y).
 
The relative fault of the Company on the one hand and the Placement Agents on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Placement Agents and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.
 
The Company and the Placement Agents agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Placement Agents were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.
 
Notwithstanding the provisions of this Section 7, no Placement Agent shall be required to contribute any amount in excess of the total fee received by such Placement Agent pursuant to Section 1(b) hereof.
 
No person guilty of 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.
 
For purposes of this Section 7, each person, if any, who controls a Placement Agent within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and each Placement Agent’s Affiliates, employees and agents shall have the same rights to contribution as such Placement Agent, and each director, officer, agent and employee of the Company, and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company.
 
Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this Section 7, notify such party or parties from whom contribution may be sought, but the omission so to notify such party or parties from whom contribution may be sought shall not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have hereunder or otherwise than under this Section 7. No party shall be liable for contribution with respect to any action, suit, proceeding or claim settled without its written consent. The Placement Agents’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective amounts of placement agent fees each has actually received pursuant to this Agreement and not joint.

 
SECTION 9.  Representations and Agreements to Survive Delivery.
 
All representations, warranties, and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of any Placement Agent or its Affiliates or selling agents, any person controlling any Placement Agent, its officers or directors or any person controlling the Company, and (ii) delivery of and payment for the Securities.
 
SECTION 10.  Termination of Agreement.
 
(a)  Termination; General. The Placement Agents may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Date (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus or the General Disclosure Package, any material adverse change in the condition, financial or otherwise, or in the earnings or business affairs of the Company and its subsidiaries taken as a whole, whether or not arising in the ordinary course of business, so material and adverse as to make it impractical or inadvisable to proceed with the placement or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Placement Agents, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the Nasdaq Global Market, or if trading generally on the New York Stock Exchange or in the Nasdaq Global Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the National Association of Securities Dealers, Inc. or any other governmental authority, or (iv) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or (v) if a banking moratorium has been declared by either Federal or New York authorities. Notice of any termination of this Agreement shall be promptly given to the Company by telecopy or telephone and shall be subsequently confirmed by letter.
 
(b)  Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 2, 6, 7 and 8 shall survive such termination and remain in full force and effect.
 
SECTION 11.  Default by the Company.
 
If the Company shall fail at the Closing Date to sell the number of Securities that it is obligated to sell hereunder due exclusively to its failure to perform its obligations to deliver the Securities as contemplated hereunder against payment therefore and no alternate delivery arrangements are arranged  and agreed between the Company and the Placement Agent, then this Agreement shall terminate without any liability on the part of any nondefaulting party; provided, however, that the provisions of Sections 2, 4, 6, 7 and 8 shall remain in full force and effect. No action taken pursuant to this Section shall relieve the Company from liability, if any, in respect of such default.
 
SECTION 12.  Notices.
 
All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Placement Agents shall be directed to the Representative at One Bush Street, Suite 1700, San Francisco, CA 94104, attention of Richard Osgood; notices to the Company shall be directed to it at 35 NE Industrial Road, Branford, CT 06405, attention of Stephen R. Davis, Chief Operating Officer, with a copy to Milbank, Tweed, Hadley & McCloy LLP, 1 Chase Manhattan Plaza, New York, NY 10005, attention of Robert B. Williams, Esq.

Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Placement Agents, the Company and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained.

EXHIBIT A

FORM OF ESCROW AGREEMENT

EXHIBIT B
 
PURCHASE AGREEMENT
 
Neurogen Corporation
35 NE Industrial Road
Branford, CT 06405
 
Ladies and Gentlemen:
 
The undersigned, __________________________________ (the “Investor”), hereby confirms its agreement with you as follows:
 
This Purchase Agreement (the “Agreement”) is made as of December 18, 2006 between Neurogen Corporation, a Delaware corporation (the “Company”), and the Investor.

The Company has authorized the sale and issuance of up to 6,993,000 shares (the “Securities”) of common stock, par value $0.025 per share (the “Common Stock”), of the Company to certain investors (the “Offering”). The Offering and issuance of the Securities have been registered under the Securities Act of 1933, as amended (the “Act”), pursuant to the Company’s Registration Statement on Form S-3, initially filed on August 16, 2002 (No. 333-98237), as amended (the “Registration Statement”).
 
The Company and the Investor agree that the Investor will purchase from the Company and the Company will issue and sell to the Investor ___________________ Securities, for a purchase price of $5.72 per share or an aggregate purchase price of $ ________________, pursuant to the Terms and Conditions for Purchase of Securities attached hereto as Annex I and incorporated herein by reference as if fully set forth herein. The Investor acknowledges that the offering is not being underwritten by the Placement Agents (as defined in the Placement Agency Agreement dated December 18, 2006, between the Company and the Placement Agents (the “Placement Agency Agreement”)) and that there is no minimum offering amount. Certificates representing the shares of Common Stock purchased by the Investor will not be issued to the Investor; instead, such shares of Common Stock will be credited to the Investor using customary procedures for book-entry transfer through the facilities of The Depository Trust Company (“DTC”). This offering will not clear directly through the Placement Agents acting in such capacity. Consequently, the Investor must instruct their individual broker how to settle the transaction.
 
The Investor represents that, except as fully described on Annex II attached hereto, (a) it has had no position, office or other material relationship within the past three years with the Company or persons known to it to be affiliates of the Company, (b) neither it, nor any group of which it is a member or to which it is related, beneficially owns (including the right to acquire or vote) any securities of the Company, (c) it has no direct or indirect affiliation or association with any NASD member as of the date hereof and (d) after giving effect to the Offering, neither the undersigned Investor nor any group of Investors (as identified in a public filing made with the Commission) of which the undersigned Investor is a part, in connection with the offering of the Shares will acquire, or obtain the right to acquire, 20% or more of the Common Stock (or securities convertible or exercisable for Common Stock) or the voting power of the Company.
 
The Investor hereby consents to the receipt of the Company’s prospectus supplement, dated December 18, 2006 (the “Prospectus Supplement”) and the accompanying base prospectus, dated February 13, 2003 (the “Base Prospectus” and together with the Prospectus Supplement, the “Prospectus”), in portable document format, or PDF, via electronic mail.
 
Your attention is directed to the “Instruction Sheet for Investors” attached hereto for directions regarding this Purchase Agreement.

2.  Agreement to Sell and Purchase the Securities; Subscription Date.
 
2.1  Upon the terms and subject to the conditions hereinafter set forth, at the Closing (as defined in Section 3), the Company will sell to the Investor, and the Investor will purchase from the Company, the number of Securities set forth on the signature page hereto, at the purchase price set forth in the fourth paragraph of the Purchase Agreement to which this Annex I is attached.

The Escrow Agent will invest such funds in a non-interest bearing account (the “Escrow Account”) in accordance with Rule 15c2-4 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Escrow Agent will not accept any Investor funds until the date of the Prospectus Supplement. The Company will deposit the Securities with DTC upon receiving notice from the Placement Agents.

5.1  The Company has full corporate power and authority to (a) enter into the Placement Agency Agreement and the Agreement and to consummate the transactions contemplated hereby and thereby, including the sale of the Securities, and (b) authorize, execute, issue, and deliver the Securities as contemplated by the Placement Agency Agreement and the Agreement.
 
5.2  The Placement Agency Agreement and the Agreement have been duly authorized, executed and delivered by the Company, and, assuming due authorization, execution and delivery by the Investor of the Agreement, constitute legal and binding obligations of the Company, enforceable in accordance with their terms, except to the extent that rights to indemnity hereunder or under the Placement Agency Agreement may be limited by federal or state securities laws and except as such enforceability may be limited by bankruptcy, fraudulent conveyance, insolvency, reorganization or similar laws affecting the rights of creditors generally and subject to general principles of equity.
 
6.  Representations, Warranties and Covenants of the Investor. The Investor hereby represents and warrants to, and covenants with, the Company, as follows:
 
7.  The Investor, if outside the United States, will comply with all applicable laws and regulations in each foreign jurisdiction in which it purchases, offers, sells or delivers Securities or has in its possession or distributes any offering material, in all cases at its own expense.
 
7.1  The Investor has full power and authority to enter into this Agreement and to consummate the transactions contemplated hereby, including the purchase of the Securities as contemplated by this Agreement.

7.3  The Investor understands that nothing in the Prospectus, this Agreement or any other materials presented to the Investor in connection with the purchase and sale of the Securities constitutes legal, tax or investment advice. The Investor has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of Securities.
 
7.4  The making, execution and performance of this Agreement by the Investor and the consummation of the transactions contemplated herein will not conflict with or result in a breach or violation of any of the terms and provisions of, or constitute a default under, (i) the charter, bylaws or other organizational documents of such Investor, as applicable, or (ii) any law, order, rule, regulation, writ, injunction, judgment or decree of any court, administrative agency, regulatory body, government or governmental agency or body, domestic or foreign, having jurisdiction over such Investor or its properties, except for any conflict, breach, violation or default which is not reasonably likely to have a material adverse effect on such Investor’s performance of its obligations hereunder or the consummation of the transactions contemplated hereby.

Limitation on the Use of Net Operating Loss Carryforwards (“NOLs”) and Tax Credits
 
As previously disclosed, the Company’s ability to utilize its NOLs and tax credits may be limited if it undergoes or has undergone an ownership change, as defined in section 382 of the Internal Revenue Code, as a result of changes in the ownership of outstanding stock. An ownership change generally occurs if the percentage of stock owned by one or more stockholders who own, directly or indirectly, 5% or more of the value of the Company’s outstanding stock (or are otherwise treated as 5% stockholders under section 382 and the regulations promulgated thereunder) has increased by more than 50 percentage points over the lowest percentage of the Company’s outstanding stock owned by these stockholders at any time during the testing period, which is generally the three-year period preceding the potential ownership change. In the event of an ownership change, section 382 imposes an annual limitation on the amount of post-ownership change taxable income a corporation may offset with pre-ownership change NOLs.
 
 
In 2006, the Company reviewed its changes in ownership through a testing date of December 31, 2005, and determined that an ownership change occurred in 2005. The Company is currently reviewing the impact of the change of ownership on the utilization of its NOLs and tax credits but has not completed its analysis. However, the change of ownership could have the effect of reducing the amount of NOLs and tax credits existing at the date of the ownership change that the Company may utilize to offset taxable income in the taxable years following the ownership change.
