5.	Indemnification.

5.1 Indemnification of the Underwriter.

5.1.1. General. Subject to the conditions set forth below, the Company agrees to indemnify and hold harmless the Underwriter, and each dealer selected by the Underwriter 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 the Underwriter (“Controlling Person”) 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 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 the Underwriter and the Company or between the Underwriter 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) the Preliminary Prospectus, the Registration Statement 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); or (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 Public Securities under the securities laws thereof or filed with the Commission, any state securities commission or agency, NASDAQ Capital Market or any securities exchange; or the omission or alleged omission therefrom 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 the Underwriter by or on behalf of the Underwriter expressly for use in the Preliminary Prospectus, the Registration Statement 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 Section 5.1.1 shall not inure to the benefit of any Underwriter to the extent that any loss, liability, claim, damage or expense of the 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 3.3 hereof. The Company agrees promptly to notify the Underwriter 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 Public Securities or in connection with the Registration Statement or Prospectus.

5.1.2. Procedure. If any action is brought against the 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, the Underwriter, such Selected Dealer or Controlling Person, as the case may be, 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 the Underwriter or such Selected Dealer or Controlling Person, as the case may be) and payment of actual expenses. Such Underwriter, such Selected Dealer or Controlling Person shall have the right to employ a single counsel in any such case, but the fees and expenses of such counsel shall be at the expense of the Underwriter, such 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 (in addition to local counsel), Selected Dealer and/or Controlling Person shall be borne by the Company. Notwithstanding anything to the contrary contained herein, if any 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. The Underwriter 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 Underwriter, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions made in the Preliminary Prospectus, the Registration Statement 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 the Underwriter by or on behalf of the Underwriter expressly for use in the Preliminary Prospectus, the Registration Statement 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 the Preliminary Prospectus, the Registration Statement or Prospectus or any amendment or supplement thereto or any application, and in respect of which indemnity may be sought against the Underwriter, the 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 Underwriter 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 Underwriter 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 Underwriter, as incurred, in such proportions that the Underwriter is 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. Notwithstanding the provisions of this Section 5.3.1, the Underwriter shall not 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 the 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 the Underwriter or the Company, as applicable, and each person, if any, who controls the Underwriter or the Company, as applicable, within the meaning of Section 15 of the Act shall have the same rights to contribution as the Underwriter 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 failure 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 affected by such party seeking contribution on account of any settlement of any claim, action or proceeding affected by such party seeking contribution without the written consent of such contributing party. The contribution provisions contained in this Section 5.3.2 are intended to supersede, to the extent permitted by law, any right to contribution under the Act, the Exchange Act or otherwise available.

6.	Additional Covenants.

6.1 Board Composition and Board Designations. The Company shall ensure that for a period of three years from the Closing Date: (i) the qualifications of the persons serving as board members and the overall composition of the board comply with the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 and the rules promulgated thereunder and with the listing requirements of, NASDAQ Capital Market or any other national securities exchange or national securities association, as the case may be, in the event the Company seeks to have its Public Securities listed on another exchange or quoted on an automated quotation system, and (ii) if applicable, at least one member of the board of directors qualifies as a “financial expert” as such term is defined under the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 and the rules promulgated thereunder.

6.2 Right of First Refusal. The Company agrees that if all of the Firm Units are sold in accordance with the terms of this Underwriting Agreement, the Underwriter shall have an irrevocable right for a period of twelve (12) months from the Closing Date to purchase for its account or to sell for the account of the Company, or any subsidiary of or successor to the Company any securities of the Company or any such subsidiary or successor which the Company or any such subsidiary or successor may seek to sell in public or private equity and public debt offerings of the Company or any subsidiary of or successor to the Company of its subsidiaries, whether with or without or through an underwriter, placement agent or broker-dealer. The Company and any such subsidiary or successor will consult the Underwriter with regard to any such proposed financing and will offer the Underwriter the opportunity to purchase or sell any such securities on terms not more favorable to the Company or any such subsidiary or successor, as the case may be, than it or they can secure elsewhere. If the Underwriter fails to accept such offer within 10 business days after the mailing of a notice containing the material terms of the proposed financing proposal by registered mail or overnight courier service addressed to the Underwriter, then the Underwriter shall have no further claim or right with respect to the financing proposal contained in such notice. If, however, the terms of such financing proposal are subsequently modified in any material respect, the preferential right referred to herein shall apply to such modified proposal as if the original proposal had not been made. The Underwriter’s failure to exercise its preferential right with respect to any particular proposal shall not affect its preferential rights relative to future proposals during the aforesaid twelve (12) month period. The Company shall have the right, at its option, to designate the Underwriter as lead underwriter or co-manager of any underwriting group or co-placement agent of any proposed financing in satisfaction of its obligations hereunder, and the Underwriter shall be entitled to receive as its compensation 50% of the compensation payable to the underwriting or placement agent group when serving as co-manager or co-placement agent and 33% of the compensation payable to the underwriting or placement agent group when serving as co-manager or co-placement agent with respect to a proposed financing in which there are three co-managing or lead underwriters or co-placement agents. For avoidance of doubt, the right of first refusal set forth in this Section 6.1 shall not apply to any resale offerings of the Company’s securities by its security holders.

6.3 Prohibition on Press Releases and Public Announcements. The Company will not issue press releases or engage in any other publicity, without the Underwriter’s prior written consent, for a period ending at 5:00 p.m. Eastern time on the first business day following the 40th day following the Closing Date, other than normal and customary releases issued in the ordinary course of the Company’s business or as otherwise required by law (including without limitation the filing of any reports required to be filed under the Exchange Act). The Company covenants to at all times adhere to all “gun jumping” and “quiet period” rules and regulations of the Commission.

7.	Effective Date of this Agreement and Termination Thereof.

7.1 Effective Date. This Agreement shall become effective when both the Company and the Underwriter have executed the same and delivered counterparts of such signatures to the other party.

7.2 Termination. The Underwriter shall have the right to terminate this Agreement at any time prior to the Closing Date or the Option 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 NASDAQ Capital Market (or any successor thereto) or any other securities exchange or any over-the-counter market shall have been suspended or materially limited, or minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been required by FINRA 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 markets, or (vi) if the Company or the Subsidiary 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 Firm Units or Option Units, or (vii) if the Company is in material breach of any of its representations, warranties or covenants hereunder, or (viii) if the Underwriter shall have become aware after the date hereof of such a material adverse change in the conditions or prospects of the Company or the Subsidiary, or such adverse material change in general market conditions as in the Underwriter’s judgment would make it impracticable to proceed with the offering, sale and/or delivery of the securities or to enforce contracts made by the Underwriter for the sale of the securities.

7.3 Expenses. In the event that this Agreement shall not be carried out for any reason whatsoever, within the time specified herein or any extensions thereof pursuant to the terms herein, the Company shall be obligated to pay to the Underwriter its actual accountable expenses incurred through the termination date up to a maximum of $100,000 (provided, however, that such expense cap in no way limits or impairs the indemnification and contribution provisions of this Agreement) for all such expenses (which expenses will include, but will not be limited to, all reasonable fees and disbursements of the Underwriter’s counsel, travel, lodging and other “road show” expenses, mailing, printing and reproduction expenses, and any expenses incurred by the Underwriter in conducting its due diligence, including background checks of the Company’s officers and directors), less amounts, if any, previously paid to the Underwriter in reimbursement for such expenses or as an advance.

7.4 Indemnification. Notwithstanding any contrary provision contained in this Agreement, any election hereunder or any termination of this Agreement, and whether or not this Agreement is otherwise carried out, the provisions of Section 5 shall not be in any way effected by, such election or termination or failure to carry out the terms of this Agreement or any part hereof.

7.5 Survival. Except as set forth herein, all representations, warranties and agreements contained in this Agreement shall be deemed to be representations, warranties and agreements as of the Closing Date or the Option Closing Date, if any, and such representations, warranties and agreements of the Underwriter 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 the Underwriter, the Company or any controlling person, and shall survive termination of this Agreement or the issuance and delivery of the Public Securities to the 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.

8.	Miscellaneous.

8.1 Notices. All communications hereunder, except as herein otherwise specifically provided, shall be in writing and shall be mailed (registered or certified mail, return receipt requested), personally delivered or sent by facsimile transmission and confirmed and shall be deemed given when so delivered or faxed and confirmed or if mailed, two days after such mailing.

Lock-Up Agreement

___________ __, 2011

▇▇▇▇▇▇ & ▇▇▇▇▇▇▇, LLC

▇▇▇▇ ▇▇▇▇▇▇ ▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇▇

▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇

Ladies and Gentlemen:

The undersigned understands that ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇, LLC (the “Underwriter”) proposes to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Novelos Therapeutics, Inc., a Delaware corporation (the “Company”), providing for the public offering (the “Public Offering”) by the Underwriter of up to $15 million (not including over-allotments) in aggregate offering price of shares of common stock, par value $0.00001 per share, of the Company (the “Common Stock”).

To induce the Underwriter to continue its efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of the Underwriter, the undersigned will not, during the period (the “Lock-Up Period”) commencing on the date hereof and ending 180 days after the date of the final prospectus relating to the Public Offering (the “Prospectus”), (1) offer, pledge, sell, contract to sell, grant, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock (“Shares”) or any securities convertible into or exercisable or exchangeable for Shares, (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Shares, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Shares or such other securities, in cash or otherwise, (3) make any demand for or exercise any right or cause to be filed a registration statement, including any amendments thereto, with respect to the registration of any Shares or securities convertible into or exercisable or exchangeable for Shares or other securities of the Company, or (4) publicly disclose the intention to do any of the foregoing. Notwithstanding the foregoing, the undersigned may transfer Shares without the prior consent of the Underwriter in connection with (a) transactions relating to Shares or other securities acquired in open market transactions after the completion of the Public Offering, provided that no filing under Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), shall be required or shall be voluntarily made in connection with subsequent sales of Shares or other securities acquired in such open market transactions, (b) transfers of Shares or any security convertible into Shares as a bona fide gift, by will or intestacy or to a family member or trust for the benefit of a family member; provided that in the case of any transfer or distribution pursuant to clause (b), (i) each donee or distributee shall sign and deliver a lock-up letter substantially in the form of this letter agreement and (ii) no filing under Section 16(a) of the Exchange Act, reporting a reduction in beneficial ownership of Shares, shall be required or shall be voluntarily made during the Lock-up Period, (c) transfer of Shares to a charity or educational institution, or (d) if the undersigned is, or directly or indirectly controls, a corporation, partnership, limited liability company or other business entity, any transfers of Shares to any shareholder, partner or member of, or owner of similar equity interests in, the undersigned, as the case may be, if, in any such case, such transfer is not for value. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s Shares except in compliance with this Agreement.

If the undersigned is an officer or director of the Company, (i) the Underwriter agrees that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with any transfer of Shares, the Underwriter will notify the Company of the impending release or waiver, and (ii) the Company will announce, in accordance with the Underwriting Agreement, the impending release or waiver by issuing a press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted by the Underwriter hereunder to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if both (a) the release or waiver is effected solely to permit a transfer not for consideration, and (b) the transferee has agreed in writing to be bound by the same terms described in this letter that are applicable to the transferor, to the extent and for the duration that such terms remain in effect at the time of the transfer.

If (i) the Company issues an earnings release or material news, during the last 17 days of the Lock-Up Period, or (ii) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, the restrictions imposed by this agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release, unless the Underwriter waives such extension.

No provision in this agreement shall be deemed to restrict or prohibit the exercise or exchange by the undersigned of any option or warrant to acquire Shares, or securities exchangeable or exercisable for or convertible into Shares, provided that the undersigned does not transfer the Shares acquired on such exercise or exchange during the Lock-Up Period, unless otherwise permitted pursuant to the terms of this letter agreement. In addition, no provision herein shall be deemed to restrict or prohibit the entry into or modification of a so-called “10b5-1” plan at any time (other than the entry into or modification of such a plan in such a manner as to cause the sale of any Shares or any securities convertible into or exercisable or exchangeable for Shares within the Lock-Up Period).

The undersigned understands that the Company and the Underwriter are relying upon this letter agreement in proceeding toward consummation of the Public Offering. The undersigned further understands that this agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns.

The undersigned understands that, if the Underwriting Agreement is not executed by the Company, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Shares to be sold thereunder this agreement shall be void and of no further force or effect.

Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriter.

Very truly yours,

The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s Shares except in compliance with this Agreement.
