(aa) ERISA COMPLIANCE. The Company and each "Employee Plan" (as defined below) established or maintained by the Company or its "ERISA Affiliates" (as defined below) are in compliance in all material respects with the Employee Retirement Income Security Act of 1974, as amended, and the regulations and published interpretations thereunder (collectively, "ERISA"), the Internal Revenue Code of 1986, as amended, and the regulations and published interpretations thereunder (collectively, the "Code"), and all other applicable laws and regulations.

No Employee Plan is an "employee pension benefit plan" (within the meaning of Section 3(2) of ERISA) subject to Title IV of ERISA, and neither the Company nor any ERISA Affiliate has ever partially or fully withdrawn from any such plan. No Employee Plan is a Multiemployer Plan or "single-employer plan under multiple controlled groups" as described in Section 4063 of ERISA, and neither the Company nor any ERISA Affiliate has ever contributed to or had an obligation to contribute, or incurred any liability in respect of a contribution, to any Multiemployer Plan (as such term is defined in Section 3(37) of ERISA). Each Employee Plan that is a "group health plan" (within the meaning of Code Section 5000(b)(1)) has been operated in material compliance with all laws applicable to such plan, its terms, and with the group health plan continuation coverage requirements of Section 4980B of the Code and Sections 601 through 608 of ERISA ("COBRA Coverage"), Section 4980D of the Code and Sections 701 through 707 of ERISA, Title XXII of the Public Health Service Act and the provisions of the Social Security Act, to the extent such requirements are applicable.

No Employee Plan currently or previously maintained by the Company provides any post-termination health care or life insurance benefits, and neither the Company nor its ERISA Affiliates has any obligations (whether written or oral) to provide any post-termination benefits in the future (except for COBRA Coverage or coverage required by any other applicable law).

(dd) COMPLIANCE WITH LAWS. The Company is conducting business in compliance with all applicable laws, rules and regulations of the jurisdictions in which it is conducting business, except where the failure to so comply would not result in a Material Adverse Change.

(hh) NO MARGIN SECURITIES. The Company does not own any "margin securities" as that term is defined in Regulation U of the Board of Governors of the Federal Reserve System (the "Federal Reserve Board"), and none of the proceeds from the sale of Common Shares will be used, directly or indirectly, for the purpose of purchasing or carrying any margin security, for the purpose of reducing or retiring any indebtedness which was originally incurred to purchase or carry any margin security or for any other purpose which might cause any of the Common Shares to be considered a "purpose credit" within the meanings of Regulation T, U or X of the Federal Reserve Board.

The animal studies and other preclinical tests conducted by or on behalf of the Company that are described in the Registration Statement and Prospectus or the results of which are referred to in the Registration Statement and Prospectus were and, if still pending, are being conducted in all material respects in accordance with experimental protocols, procedures and controls generally used by qualified experts in the preclinical study of new drugs or diagnostics as applied to comparable products to those being developed by the Company. The descriptions of the results of such studies and tests contained in the Registration Statement and Prospectus are accurate and complete in all material respects. Any certificate signed by an officer of the Company and delivered to the Representatives or to counsel for the Underwriters shall be deemed to be a representation and warranty by the Company to each Underwriter as to the matters set forth therein.

Section 2. PURCHASE, SALE AND DELIVERY OF THE COMMON SHARES. (a) THE FIRM COMMON SHARES. On the basis of the representations, warranties and agreements herein contained, and upon the terms but subject to the conditions herein set forth, (i) the Company agrees to issue and sell to the several Underwriters the Firm Common Shares and (ii) the Underwriters agree, severally and not jointly, to purchase from the Company the respective number of Firm Common Shares set forth opposite their names on Schedule A. The purchase price per Firm Common Share to be paid by the several Underwriters to the Company shall be $[___] per share. (b) THE FIRST CLOSING DATE. Delivery of certificates for the Firm Common Shares to be purchased by the Underwriters and payment therefor shall be made at the offices of BAS, 9 West 57th Street, New York, NY (or such other place as may be agreed to by the Company and the Representatives) at 9:00 a.m. New York time, on [___], or such other time and date not later than 1:30 p.m. New York time, on [___] as the Representatives and the Company shall agree (the time and date of such closing are called the "First Closing Date"). (c) THE OPTIONAL COMMON SHARES; THE SECOND CLOSING DATE. In addition, on the basis of the representations, warranties and agreements herein contained, and upon the terms but subject to the conditions herein set forth, the Company hereby grants an option to the several Underwriters to purchase, severally and not jointly, up to an aggregate of [___] Optional Common Shares from the Company at the purchase price per share to be paid by the Underwriters for the Firm Common Shares. The option granted hereunder is for use by the Underwriters solely in covering any over-allotments in connection with the sale and distribution 12 of the Firm Common Shares. The option granted hereunder may be exercised at any time (but not more than once) upon notice by the Representatives to the Company, which notice may be given at any time within 30 days after the date of this Agreement. Such notice shall set forth (i) the aggregate number of Optional Common Shares as to which the Underwriters are exercising the option, (ii) the names and denominations in which the certificates for the Optional Common Shares are to be registered and (iii) the time, date and place at which such certificates will be delivered (which time and date may be simultaneous with, but not earlier than, the First Closing Date; and in such case the term "First Closing Date" shall refer to the time and date of delivery of certificates for the Firm Common Shares and the Optional Common Shares). Such time and date of delivery, if subsequent to the First Closing Date, is called the "Second Closing Date" and shall be determined by the Representatives and shall not be earlier than three nor later than five full business days after delivery of such notice of exercise. If any Optional Common Shares are to be purchased, each Underwriter agrees, severally and not jointly, to purchase the number of Optional Common Shares (subject to such adjustments to eliminate fractional shares as the Representatives may determine) that bears the same proportion to the total number of Optional Common Shares to be purchased as the number of Firm Common Shares set forth on Schedule A opposite the name of such Underwriter bears to the total number of Firm Common Shares. The Representatives may cancel the option at any time prior to its expiration by giving written notice of such cancellation to the Company. (d) PUBLIC OFFERING OF THE COMMON SHARES. The Representatives hereby advise the Company that the Underwriters intend to offer for sale to the public, as described in the Prospectus, their respective portions of the Common Shares as soon after this Agreement has been executed and the Registration Statement has been declared effective as the Representatives, in their sole judgment, have determined is advisable and practicable. (e) PAYMENT FOR THE COMMON SHARES. Payment for the Common Shares shall be made at the First Closing Date (and, if applicable, at the Second Closing Date) by wire transfer of immediately available United States funds to an account at a bank acceptable to SG Cowen and BAS jointly, payable to the order of the Company. It is understood that the Representatives have been authorized, for their own respective accounts and the accounts of the several Underwriters, to accept delivery of and receipt for, and make payment of the purchase price for, the Firm Common Shares and any Optional Common Shares the Underwriters have agreed to purchase. Each of SG Cowen and BAS, individually and not as a Representative of the Underwriters, may (but shall not be obligated to) make payment for any Common Shares to be purchased by any Underwriter whose funds shall not have been received by the Representatives by the First Closing Date or the Second Closing Date, as the case may be, for the account of such Underwriter, but any such payment shall not relieve such Underwriter from any of its obligations under this Agreement. (f) DELIVERY OF THE COMMON SHARES. The Company shall deliver, or cause to be delivered, to the Representatives for the accounts of the several Underwriters certificates for the Firm Common Shares at the First Closing Date, against the irrevocable release of a wire transfer of immediately available United States funds for the amount of the purchase price therefor. The Company shall also deliver, or cause to be delivered, to the Representatives for the accounts of the several Underwriters, certificates for the Optional Common Shares the Underwriters have 13 agreed to purchase at the First Closing Date or the Second Closing Date, as the case may be, against the irrevocable release of a wire transfer of immediately available United States funds for the amount of the purchase price therefor. The certificates for the Common Shares shall be in definitive form and registered in such names and denominations as the Representatives shall have requested at least two full business days prior to the First Closing Date (or the Second Closing Date, as the case may be) and shall be made available for inspection on the business day preceding the First Closing Date (or the Second Closing Date, as the case may be) at a location in New York City as the Representatives may designate. Time shall be of the essence, and delivery at the time and place specified in this Agreement is a further condition to the obligations of the Underwriters. Section 3. ADDITIONAL COVENANTS OF THE COMPANY. The Company further covenants and agrees with each Underwriter as follows: (a) REPRESENTATIVES' REVIEW OF PROPOSED AMENDMENTS AND SUPPLEMENTS. During such period beginning on the date hereof and ending on the later of the First Closing Date or such date, as in the opinion of counsel for the Underwriters, the Prospectus is no longer required by law to be delivered in connection with sales by an Underwriter or dealer (the "Prospectus Delivery Period"), prior to amending or supplementing the Registration Statement (including any registration statement filed under Rule 462(b) under the Securities Act) or the Prospectus, the Company shall furnish to the Representatives for review a copy of each such proposed amendment or supplement, and the Company shall not file any such proposed amendment or supplement to which the Representatives reasonably object. (b) SECURITIES ACT COMPLIANCE. After the date of this Agreement, the Company shall promptly advise the Representatives in writing (i) of the receipt of any comments of, or requests for additional or supplemental information from, the Commission, (ii) of the time and date of any filing of any post-effective amendment to the Registration Statement or any amendment or supplement to any preliminary prospectus or the Prospectus, (iii) of the time and date that any post-effective amendment to the Registration Statement becomes effective and (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto or of any order preventing or suspending the use of any preliminary prospectus or the Prospectus, or of any proceedings to remove, suspend or terminate from listing or quotation the Common Stock from any securities exchange or inter-dealer quotation system or securities market upon which it is listed for trading or included or designated for quotation, or of the threatening or initiation of any proceedings for any of such purposes. If the Commission shall enter any such stop order at any time, the Company will use its best efforts to obtain the lifting of such order at the earliest possible moment. Additionally, the Company shall comply with the provisions of Rules 424(b), 430A and 434, as applicable, under the Securities Act and will use its reasonable efforts to confirm that any filings made by the Company under such Rule 424(b) were received in a timely manner by the Commission. The Company will supply the Representatives with copies of all correspondence to and from, and all documents issued to and by, the Commission in connection with the registration of the Common Shares under the Securities Act. (c) AMENDMENTS AND SUPPLEMENTS TO THE PROSPECTUS AND OTHER SECURITIES ACT MATTERS. If, during the Prospectus Delivery Period, any event shall occur or condition exist as a 14 result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus is delivered to a purchaser, not misleading, or if in the opinion of the Representatives or counsel for the Underwriters it is otherwise necessary to amend or supplement the Prospectus to comply with law, the Company agrees, at its own expense, to promptly prepare (subject to Section 3(a) hereof), file with the Commission and furnish to the Underwriters and to dealers, amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus is delivered to a purchaser, be misleading, or so that the Prospectus, as amended or supplemented, will comply with law. The Company will not take any action prior to the expiration of the Prospectus Delivery Period which would require the Prospectus to be amended or supplemented pursuant to this Section 3(c). The Underwriters shall cease using the Prospectus upon receiving written notice from the Company that an amendment or supplement is required under this Section 3(c). (d) COPIES OF ANY AMENDMENTS AND SUPPLEMENTS TO THE PROSPECTUS. The Company agrees to furnish the Representatives, without charge, during the Prospectus Delivery Period, as many copies of the Prospectus and any amendments and supplements thereto as the Representatives may reasonably request. (e) BLUE SKY COMPLIANCE. The Company shall cooperate with the Representatives and counsel for the Underwriters to qualify or register the Common Shares for sale under (or obtain exemptions from the application of) the state securities or blue sky laws or Canadian provincial securities laws of those jurisdictions designated by the Representatives, shall comply with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Common Shares. The Company shall not be required to qualify as a foreign corporation or to take any action that would subject it to general service of process in any such jurisdiction where it is not presently qualified or where it would be subject to taxation as a foreign corporation. The Company will advise the Representatives promptly of the suspension of the qualification or registration of (or any such exemption relating to) the Common Shares for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of the issuance of any order suspending such qualification, registration or exemption, the Company shall use its best efforts to obtain the withdrawal thereof at the earliest possible moment. (f) USE OF PROCEEDS. The Company shall apply the net proceeds from the sale of the Common Shares sold by it in the manner described under the caption "Use of Proceeds" in the Prospectus. (g) TRANSFER AGENT. The Company shall engage and maintain, at its expense, a registrar and transfer agent for the Common Stock. (h) EARNINGS STATEMENT. As soon as practicable, the Company will make generally available to its security holders and to the Representatives an earnings statement (which need not be audited) covering the twelve-month period ending [___] that satisfies the provisions of Section 11(a) of the Securities Act. 15 (i) PERIODIC REPORTING OBLIGATIONS. During the Prospectus Delivery Period, the Company shall file, on a timely basis, with the Commission and the Nasdaq National Market all reports and documents required to be filed under the Exchange Act. Additionally, the Company shall report the use of proceeds from the issuance of the Common Shares as may be required under Rule 463 under the Securities Act. (j) DIRECTED SHARE PROGRAM. In connection with the Directed Share Program, the Company will use reasonable efforts to ensure that the Directed Shares will be restricted to the extent required by the NASD under NASD Rule 2790 from sale, transfer, assignment, pledge or hypothecation for a period following the date of the effectiveness of the Registration Statement. If so required, the Company will direct the transfer agent to place stop transfer restrictions upon such securities for such period of time. Should the Company release, or seek to release, from such restrictions any of the Directed Shares, the Company agrees to reimburse the Underwriters for any reasonable expenses (including, without limitation, legal expenses) they incur in connection with such release. (k) QUOTATION. The Company will use its best efforts to include, subject to notice of issuance, the Common Shares on the Nasdaq National Market. (l) AGREEMENT NOT TO OFFER OR SELL ADDITIONAL SECURITIES. During the period commencing on the date hereof and ending on the 180th day following the date of the Prospectus, the Company will not, without the prior written consent of SG Cowen and BAS jointly (which consent may be withheld at the sole discretion of SG Cowen or BAS), directly or indirectly, sell, offer, contract or grant any option to sell, pledge, transfer or establish an open "put equivalent position" within the meaning of Rule 16a-1(h) under the Exchange Act, or otherwise dispose of or transfer, or announce the offering of, or file any registration statement under the Securities Act (other than a registration statement on Form S-8) in respect of, any shares of Common Stock, options or warrants to acquire shares of the Common Stock or securities exchangeable or exercisable for or convertible into shares of Common Stock (other than as contemplated by this Agreement with respect to the Common Shares); provided, however, that the Company may issue shares of its Common Stock or options to purchase its Common Stock, or Common Stock upon exercise of options, pursuant to any stock option, stock bonus or other stock plan or arrangement described in the Registration Statement and Prospectus, but only if the holders of such shares, options, or shares issued upon exercise of such options, agree in writing not to sell, offer, dispose of or otherwise transfer any such shares or options during such 180 day period without the prior written consent of SG Cowen and BAS jointly (which consent may be withheld at the sole discretion of the SG Cowen or BAS). (m) INVESTMENT LIMITATION. The Company shall not invest, or otherwise use the proceeds received by the Company from its sale of the Common Shares in such a manner as would require the Company or any of its subsidiaries to register as an investment company under the Investment Company Act. (n) NO MANIPULATION OF PRICE. The Company will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, the stabilization or manipulation of the price of any securities of the Company. 16 (o) EXISTING LOCK-UP AGREEMENT. The Company will enforce all existing agreements between the Company and any of its security holders that prohibit the sale, transfer, assignment, pledge or hypothecation of any of the Company's securities in connection with the Company's initial public offering. In addition, the Company will direct the transfer agent to place stop transfer restrictions upon any such securities of the Company that are bound by such existing "lock-up" agreements for the duration of the periods contemplated in such agreements. (p) NO PRESS RELEASES OR CONFERENCES. Prior to the First Closing Date and, with respect to the Optional Common Shares, the Second Closing Date, the Company will not issue any press release or other communication directly or indirectly or hold any press conference with respect to the Company, its condition, financial or otherwise, or earnings, business affairs or business prospects, without first providing written notification to each Representative. (q) NO ACTIVE TRADING IN OR RAISING THE PRICE OF THE COMMON SHARES. In connection with the offering of the Common Shares, until SG Cowen and BAS shall have jointly notified the Company of the completion of the resale of the Common Shares, the Company will not, and will cause its affiliated purchasers (as defined in Regulation M under the Exchange Act) not to, either alone or with one or more other persons, bid for or purchase, for any account in which it or any of its affiliated purchasers has a beneficial interest, any Common Shares, or attempt to induce any person to purchase any Common Shares; and will not make bids or purchase for the purpose of creating actual, or apparent, active trading in or of raising the price of the Common Shares.

The Company agrees to indemnify and hold harmless each Underwriter, its officers and employees, and each person, if any, who controls any Underwriter within the meaning of the Securities Act and the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Underwriter or such controlling person may become subject, under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, or, if applicable, the laws or regulations of foreign jurisdictions where Directed Shares have been offered, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Company), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon, in whole or in part, (A)(i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment thereto, including any information deemed to be a part thereof pursuant to Rule 430A or Rule 434 under the Securities Act, 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 (ii) any untrue statement or alleged untrue statement of a material fact contained in any preliminary 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; or (iii) any inaccuracy in the representations and warranties of the Company contained herein; or (iv) any failure of the Company to perform its obligations hereunder or under law; or (v) any act or failure to act or any alleged act or failure to act by any Underwriter in connection with, or relating in any manner to, the Common Stock or the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon any matter covered by clause (i) or (ii) above, provided that the Company shall not be liable under this clause (v) to the extent that a court of competent jurisdiction shall have determined by a final judgment that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by such Underwriter through its bad faith or willful misconduct, and (B) the violation of any 22 applicable laws or regulations of foreign jurisdictions where Directed Shares have been offered; and to reimburse each Underwriter and each such controlling person for any and all expenses (including the fees and disbursements of counsel chosen by SG Cowen and/or BAS) as such expenses are reasonably incurred by such Underwriter or such controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by the Representatives expressly for use in the Registration Statement, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto); and provided, further, that with respect to any preliminary prospectus, the foregoing indemnity agreement shall not inure to the benefit of any Underwriter from whom the person asserting any loss, claim, damage, liability or expense purchased Common Shares, or any person controlling such Underwriter, if copies of the Prospectus were timely delivered to the Underwriter pursuant to Section 2 and a copy of the Prospectus (as then amended or supplemented if the Company shall have furnished any amendments or supplements thereto) was not sent or given by or on behalf of such Underwriter to such person, if required by law so to have been delivered, at or prior to the written confirmation of the sale of the Common Shares to such person, and if the Prospectus (as so amended or supplemented) would have cured the defect giving rise to such loss, claim, damage, liability or expense. The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Company may otherwise have. (b) INDEMNIFICATION OF THE COMPANY, ITS DIRECTORS AND OFFICERS. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, each of its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Company, or any such director, officer or controlling person may become subject, under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Underwriter), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto), or arises out of or is based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any preliminary prospectus, the Prospectus (or any amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Company by the Representatives expressly for use therein; and to reimburse the Company, or any such director, officer or controlling person for any legal and other expense reasonably incurred by the Company, or any such director, officer or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The Company hereby acknowledges that the only information that the Underwriters have furnished to the Company expressly for use in the Registration Statement, any preliminary prospectus or the Prospectus (or any amendment 23 or supplement thereto) are the statements set forth (A) in the first paragraph (including the language contained in the four bullets following such paragraph) under the heading "Stabilization, Short Positions and Penalty Bids," and under the headings "Passive Market Making" and "Prospectus Delivery," in each case under the caption "Underwriting" in the Prospectus and (B) in the table in the first paragraph, as well as in the fourth paragraph under the caption "Underwriting" in the Prospectus; and the Underwriters confirm that such statements are correct. The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities that each Underwriter may otherwise have. (c) NOTIFICATIONS AND OTHER INDEMNIFICATION PROCEDURES. Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof, but the omission to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party for contribution or otherwise than under the indemnity agreement contained in this Section 8 or to the extent it is not prejudiced as a proximate result of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party's election to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel), approved by the indemnifying party (SG Cowen and BAS jointly in the case of Section 8(b) and Section 9), representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party. (d) SETTLEMENTS. The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason 24 of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 8(c) hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding. (e) INDEMNIFICATION FOR DIRECTED SHARES. In connection with the offer and sale of the Directed Shares, the Company agrees to indemnify and hold harmless the Underwriters from and against any and all losses, liabilities, claims, damages and expenses incurred by them as a result of the failure of the Participants to pay for and accept delivery of Directed Shares which, by the end of the first business day following the date of this Agreement, were subject to a properly confirmed agreement to purchase. The Company agrees to indemnify and hold harmless the Designated Underwriter, its officer and employees, and each person, if any, who controls the Designated Underwriter within the meaning of the Securities Act or the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Designated Underwriter or such controlling person may become subject, which is (i) caused by any untrue statement or alleged untrue statement of a material fact contained in any material prepared by or with the consent of the Company for distribution to Participants in connection with the Directed Share Program or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) caused by the failure of any Participant to pay for and accept delivery of Directed Shares that such Participant agreed to purchase; or (iii) related to, arising out of, or in connection with the Directed Share Program. The indemnity agreement set forth in this Section 8(e) shall be in addition to any liabilities that the Company may otherwise have. Section 9. CONTRIBUTION. If the indemnification provided for in Section 8 is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Common Shares pursuant to this Agreement or (ii) if the allocation provided by clause (i) above 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 the Underwriters, on the other hand, in connection with the statements or omissions or inaccuracies in the representations and warranties herein which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable 25 considerations. The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Common Shares pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Common Shares pursuant to this Agreement (before deducting expenses) received by the Company, and the total underwriting discount received by the Underwriters, in each case as set forth on the front cover page of the Prospectus (or, if Rule 434 under the Securities Act is used, the corresponding location on the Term Sheet) bear to the aggregate initial public offering price of the Common Shares as set forth on such cover. The relative fault of the Company, on the one hand, and the Underwriters, 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 or any such inaccurate or alleged inaccurate representation or warranty relates to information supplied by the Company, on the one hand, or the Underwriters, on the other hand, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 8(c), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in Section 8(c) with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 9; provided, however, that no additional notice shall be required with respect to any action for which notice has been given under Section 8(c) for purposes of indemnification. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters 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 in this Section 9. Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the underwriting commissions received by such Underwriter in connection with the Common Shares underwritten by it and distributed to the public. 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. The Underwriters' obligations to contribute pursuant to this Section 9 are several, and not joint, in proportion to their respective underwriting commitments as set forth opposite their names in Schedule A. For purposes of this Section 9, each officer and employee of an Underwriter and each person, if any, who controls an Underwriter within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company with the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Company. Section 10. DEFAULT OF ONE OR MORE OF THE SEVERAL UNDERWRITERS. If, on the First Closing Date or the Second Closing Date, as the case may be, any one or more of the several 26 Underwriters shall fail or refuse to purchase Common Shares that it or they have agreed to purchase hereunder on such date, and the aggregate number of Common Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase does not exceed 10% of the aggregate number of the Common Shares to be purchased on such date, the other Underwriters shall be obligated, severally, in the proportions that the number of Firm Common Shares set forth opposite their respective names on Schedule A bears to the aggregate number of Firm Common Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as may be specified by the Representatives with the consent of the non-defaulting Underwriters, to purchase the Common Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date. If, on the First Closing Date or the Second Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Common Shares and the aggregate number of Common Shares with respect to which such default occurs exceeds 10% of the aggregate number of Common Shares to be purchased on such date, and arrangements satisfactory to the Representatives and the Company for the purchase of such Common Shares are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Section 4, Section 8 and Section 9 shall at all times be effective and shall survive such termination. In any such case either the Representatives or the Company shall have the right to postpone the First Closing Date or the Second Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Registration Statement and the Prospectus or any other documents or arrangements may be effected. As used in this Agreement, the term "Underwriter" shall be deemed to include any person substituted for a defaulting Underwriter under this Section 10. Any action taken under this Section 10 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement. Section 11. TERMINATION OF THIS AGREEMENT. Prior to the First Closing Date this Agreement may be terminated by the Representatives by notice given to the Company if at any time (i) trading or quotation in any of the Company's securities shall have been suspended or limited by the Commission or by the Nasdaq National Market, or trading in securities generally on either the Nasdaq Stock Market or the New York Stock Exchange shall have been suspended or limited, or minimum or maximum prices shall have been generally established on any of such stock exchanges by the Commission or the NASD; (ii) a general banking moratorium shall have been declared by any of federal, New York, Delaware or California authorities; (iii) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity, or any change in the United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States' or international political, financial or economic conditions, as in the judgment of the Representatives is material and adverse and makes it impracticable to market the Common Shares in the manner and on the terms described in the Prospectus or to enforce contracts for the sale of securities; (iv) in the judgment of the Representatives there shall have occurred any Material Adverse Change; or (v) the Company shall have sustained a loss by strike, fire, flood, earthquake, accident or other calamity of such character as in the judgment of the Representatives may interfere materially with the conduct of the business and operations of the Company regardless of whether or not such loss shall have been insured. Any termination pursuant to this Section 11 shall be without liability on the part of (a) the Company to any 27 Underwriter, except that the Company shall be obligated to reimburse the expenses of the Representatives and the Underwriters pursuant to Sections 4 and 6, (b) any Underwriter to the Company, or (c) of any party hereto to any other party except that the provisions of Section 8 and Section 9 shall at all times be effective and shall survive such termination. Section 12. REPRESENTATIONS AND INDEMNITIES TO SURVIVE DELIVERY. The respective indemnities, contribution agreements, representations, warranties and other statements of the Company and the several Underwriters set forth in or made pursuant to this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the officers or employees of any Underwriter, any person controlling any Underwriter, the Company, the officers or employees of the Company, or any person controlling the Company, (ii) acceptance of the Common Shares and payment for them hereunder and (iii) termination of this Agreement.

B-1 EXHIBIT A FORM OF LEGAL OPINION OF COMPANY COUNSEL THE FINAL OPINION IN DRAFT FORM WILL BE ATTACHED AS EXHIBIT A AT THE TIME THIS AGREEMENT IS EXECUTED. Opinion of counsel for the Company to be delivered pursuant to Section 5(d) of the Underwriting Agreement. References to the Prospectus in this Exhibit A include any supplements thereto at the First Closing Date and, with respect to the Optional Common Shares, the Second Closing Date. (i) The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Delaware and has the corporate power and authority to carry on its business and to own, lease and operate its properties as such business and properties are described in the Prospectus. (ii) The Company is duly qualified and is in good standing as a foreign corporation authorized to do business in The Commonwealth of Massachusetts. (iii) All of the outstanding shares of Common Stock have been duly authorized and are validly issued, fully paid and nonassessable, and to such counsel's knowledge, all such shares of Common Stock were issued in compliance with a valid exemption from registration under the Securities Act. (iv) To such counsel's knowledge, except as described in the Registration Statement, there are no contracts, agreements or understandings between the Company and any person granting such person the right to require the Company to file a registration statement under the Securities Act with respect to any securities of the Company or to require the Company to include such securities with the Common Shares registered pursuant to the Registration Statement, except for any such rights as have been waived. (v) The Underwriting Agreement has been duly authorized, executed and delivered by the Company. (vi) The Common Shares have been duly authorized and, when issued and delivered to the Underwriters against payment therefor as provided by the Underwriting Agreement, will be validly issued, fully paid and nonassessable. There are no preemptive rights to purchase any of the Common Shares pursuant to, and each prior issuance of the preferred stock of the Company was not in violation of any preemptive rights under, (A) the Delaware General Corporation law or (B) any agreement filed as an exhibit to the Registration Statement. (vii) The Registration Statement has become effective under the Securities Act and, to such counsel's knowledge, no stop order suspending its effectiveness has been issued and no proceedings for that purpose are pending before or are threatened by the Commission. 1 (viii) The statements (i) in the Prospectus under the captions (A) "Risk Factors--Risks Relating to Development and Regulatory Approval--If we are not able to demonstrate therapeutic equivalence for our generic versions of complex drugs, including our M-Enoxaparin and our M-Dalteparin products to the satisfaction of the FDA, we will not obtain regulatory approval for commercial sale of our generic product candidates and our future results of operations would be adversely affected (other than the statements contained in the third paragraph under such caption)"; (B) "Risk Factors--Risks Relating to Development and Regulatory Approval--If our preclinical studies and clinical trials for our development candidates are not successful, we will not be able to obtain regulatory approval for commercial sale of our novel or improved drug candidates"; (C) "Risk Factors--Risks Relating to Development and Regulatory Approval--Failure to obtain regulatory approval in foreign jurisdictions would prevent us from marketing our products abroad"; (D) "Risk Factors--Risks Relating to Development and Regulatory Approval--Even if we obtain regulatory approvals, our marketed drugs will be subject to ongoing regulatory review. If we fail to comply with continuing United States and foreign regulations, we could lose our approvals to market drugs and our business would be seriously harmed"; (E) "Risk Factors--Risks Relating to Our Dependence on Third Parties--We depend on third-party manufacturers to manufacture products for us. If in the future we encounter difficulties in our supply or manufacturing arrangements, our business may be materially affected"; (F) "Business--Collaboration and Licenses"; (G) "Business--Manufacturing"; (H) "Business--Regulatory and Legal Matters" (other than the statements under the subsections entitled "Foreign Regulation", "Lovenox Regulatory and Legal Matters" and "Hazardous Materials"); (I) "Description of Capital Stock"; and (J) "Shares Eligible for Future Sale" and (ii) in Item 14 of Part II of the Registration Statement, insofar as such statements constitute matters of law or legal conclusions or summarize the terms of agreements, are correct in all material respects. (ix) To such counsel's knowledge, there is no action, proceeding or litigation pending or threatened against the Company before any court, governmental or administrative agency or body that is required by the Securities Act or the rules and regulations thereunder to be described in the Registration Statement or Prospectus that is not so described. (x) Except as may be required under the Securities Act and the rules and regulations of the Commission thereunder and the Exchange Act, and the rules and regulations of the Commission thereunder, no filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any United States federal or Massachusetts state governmental authority or agency is necessary for the issuance, sale and delivery of the Common Shares by the Company to the Underwriters pursuant to the Underwriting Agreement. (xi) The execution and delivery of the Underwriting Agreement by the Company and the consummation by the Company of the transactions contemplated thereby will not (A) conflict with or constitute a breach of any of the terms or provisions of, or a default under, the Certificate of Incorporation or By-laws or any indenture, loan agreement, mortgage, lease or other agreement or instrument to which the Company is a party and that is filed as an exhibit to the Registration Statement or (B) violate or conflict with any United States federal or Massachusetts state law, rule or regulation that in our experience is normally applicable in transactions of the type contemplated by the Underwriting Agreement, the Delaware General Corporation Law 2 statute, or any judgment, order or decree specifically naming the Company of which such counsel is aware. (xii) The Company is not, and after giving effect to the offering and sale of the Common Shares and application of the proceeds thereof, as described in the Prospectus, will not be an "investment company," as such term is defined in the Investment Company Act. In addition to the opinions provided above, such counsel will confirm to you as follows: In the course of acting as counsel for the Company in connection with the preparation of the Registration Statement and the Prospectus, such counsel has participated in conferences with officers and other representatives of the Company, representatives of and counsel for the Underwriters and representatives of the independent public accountants of the Company, during which the contents of the Registration Statement and the Prospectus were discussed. While the limitations inherent in the independent verification of factual matters and the character of determinations involved in the registration process are such that 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 or the Prospectus (except to the extent expressly set forth in paragraph (viii) above), subject to the foregoing and based on such participation and discussions: (a) the Registration Statement, as of its effective date, and the Prospectus, as of the date thereof (except for the financial statements, including the notes and schedules thereto, and other financial, statistical and accounting data and information, and information relating to the Underwriters and the method of distribution of the Common Shares by the Underwriters included therein or omitted therefrom, as to which such counsel need express no view) appear on their face to be appropriately responsive in all material respects to the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder; (b) no facts have come to such counsel's attention that have caused such counsel to believe that (i) the Registration Statement, as of its effective date, 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 (except as set forth in the parenthetical in clause (a) above) or (ii) the Prospectus, as of the date it was filed with the Commission pursuant to Rule[s] 424(b)([__] [and 430A]) under the Securities Act or as of the date hereof, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (except as set forth in the parenthetical in clause (a) above); and (c) such counsel is not aware of any contract or other document of a character required by the Securities Act and the applicable rules and regulations of the Commission thereunder to be filed as an exhibit to the Registration Statement that is not so filed. In rendering such opinion, such counsel may rely (A) as to matters involving the application of laws of any jurisdiction other than the General Corporation Law of the State of Delaware or the federal law of the United States, to the extent they deem proper and specified in such opinion, upon the opinion (which shall be dated the First Closing Date or the Second Closing Date, as the case may be, shall be satisfactory in form and substance to the Underwriters, 3 shall expressly state that the Underwriters may rely on such opinion as if it were addressed to them and shall be furnished to the Representatives) of other counsel of good standing whom they believe to be reliable and who are satisfactory to counsel for the Underwriters; provided, however, that such counsel shall further state that they believe that they and the Underwriters are justified in relying upon such opinion of other counsel, and (B) as to matters of fact, to the extent they deem proper, on certificates of responsible officers of the Company and public officials. 4 EXHIBIT B FORM OF LEGAL OPINION OF INTELLECTUAL PROPERTY COUNSEL THE FINAL OPINION IN DRAFT FORM WILL BE ATTACHED AS EXHIBIT B AT THE TIME THIS AGREEMENT IS EXECUTED.
