The Company will, from time to time, prepare and file such statements, reports, and other documents as are or may be required to continue such qualifications in effect for so long a period as you may reasonably request for distribution of the Stock. (g) During a period of five years commencing with the date hereof, the Company will furnish to you, and to each Underwriter who may so request in writing, copies of all periodic and special reports furnished to stockholders of the Company and of all information, documents and reports filed with the Commission. (h) Not later than the 45th day following the end of the fiscal quarter first occurring after the first anniversary of the Effective Date, the Company will make generally available to its security holders an earnings statement in accordance with Section 11(a) of the Securities Act and Rule 158 thereunder. (i) The Company agrees to pay all costs and expenses incident to the performance of obligations under this Agreement, including all costs and expenses (excluding counsel fees for Underwriters) incident to (i) the preparation, printing and filing with the Commission and the National Association of Securities Dealers, Inc. ("NASD") of the Registration Statement, any Preliminary Prospectus and the Prospectus, (ii) the furnishing to the Underwriters of copies of any Preliminary Prospectus and of the several documents required by paragraph (c) of this Section 6 to be so furnished, (iii) the printing of this Agreement and related documents delivered to the Underwriters, (iv) the preparation, printing and filing of all supplements and amendments to the Prospectus referred to in paragraph (d) of this Section 6, (v) the furnishing to you and the Underwriters of the reports and information referred to in 9 paragraph (g) of this Section 6 and (vi) the printing and issuance of stock certificates, including the transfer agent's fees. (j) The Company agrees to reimburse you, for the account of the several Underwriters, for blue sky fees and related disbursements (including counsel fees and disbursements and cost of printing memoranda for the Underwriters) paid by or for the account of the Underwriters or their counsel in qualifying the Stock under state securities or blue sky laws and in the review of the offering by the National Association of Securities Dealers, Inc. (k) THE COMPANY HEREBY AGREES THAT, WITHOUT THE PRIOR WRITTEN CONSENT OF HAMBRECHT & QUIST LLC ON BEHALF OF THE UNDERWRITERS, THE COMPANY WILL NOT, FOR A PERIOD OF 180 DAYS FOLLOWING THE EFFECTIVE DATE, DIRECTLY OR INDIRECTLY, (i) SELL, OFFER, CONTRACT TO SELL, MAKE ANY SHORT SALE, PLEDGE, SELL ANY OPTION OR CONTRACT TO PURCHASE, PURCHASE ANY OPTION OR CONTRACT TO SELL, GRANT ANY OPTION, RIGHT OR WARRANT TO PURCHASE OR OTHERWISE TRANSFER OR DISPOSE OF ANY SHARES OF COMMON STOCK OR ANY SECURITIES CONVERTIBLE INTO OR EXCHANGEABLE OR EXERCISABLE FOR OR ANY RIGHTS TO PURCHASE OR ACQUIRE COMMON STOCK OR (ii) ENTER INTO ANY SWAP OR OTHER AGREEMENT THAT TRANSFERS, IN WHOLE OR IN PART, ANY OF THE ECONOMIC CONSEQUENCES OR OWNERSHIP OF COMMON STOCK, WHETHER ANY SUCH TRANSACTION DESCRIBED IN CLAUSE (i) OR (ii) ABOVE IS TO BE SETTLED BY DELIVERY OF COMMON STOCK OR SUCH OTHER SECURITIES, IN CASH OR OTHERWISE. THE FOREGOING SENTENCE SHALL NOT APPLY TO (A) THE STOCK TO BE SOLD TO THE UNDERWRITERS PURSUANT TO THIS AGREEMENT, (B) SHARES OF COMMON STOCK ISSUED BY THE COMPANY UPON THE EXERCISE OF OPTIONS. (l) If at any time during the 25-day period after the Registration Statement becomes effective any rumor, publication or event relating to or affecting the Company shall occur as a result of which in your opinion the market price for the Stock has been or is likely to be materially affected (regardless of whether such rumor, publication or event necessitates a supplement to or amendment of the Prospectus), the Company will, after written notice from you advising the Company to the effect set forth above, forthwith prepare, consult with you concerning the substance of, and disseminate a press release or other public statement, reasonably satisfactory to you, responding to or commenting on such rumor, publication or event. (m) The Company is familiar with the Investment Company Act of 1940, as amended, and has in the past conducted its affairs, and will in the future conduct its affairs, in such a manner to ensure that the Company was not and will not be an "investment company" or a company "controlled" by an "investment company" within the meaning of the Investment Company Act of 1940, as amended, and the rules and regulations thereunder. 7. INDEMNIFICATION AND CONTRIBUTION. (a) Subject to the provisions of paragraph (f) of this Section 7, the Company agrees to indemnify and hold harmless each Underwriter and each person (including each partner or officer thereof) who controls any Underwriter within the meaning of Section 15 of the Securities Act from and against any and all losses, claims, damages or liabilities, joint or several, to which such indemnified parties or any of them may become subject under the Securities Act, the Securities Exchange Act of 1934, as amended (herein called the Exchange Act), or the common law or otherwise, and the Company agrees to reimburse each such Underwriter and controlling person for any legal or other expenses (including, except as otherwise hereinafter provided, reasonable fees and disbursements of counsel) incurred by the respective indemnified parties in connection with defending against any such losses, claims, damages or liabilities or in connection with any investigation or inquiry of, or other proceeding which may be brought against, the respective indemnified parties, in each case arising out of or based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (including the Prospectus as part thereof and any Rule 462(b) registration statement) or any post-effective amendment thereto (including any Rule 462(b) registration statement), or 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, or (ii) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus or the Prospectus (as amended or as supplemented if the Company shall have filed with the Commission any amendment thereof or supplement thereto) or the omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; PROVIDED, HOWEVER, that (1) the indemnity agreements of the Company contained in this paragraph (a) shall not apply to any such losses, claims, damages, liabilities or 10 expenses if such statement or omission was made in reliance upon and in conformity with information furnished as herein stated or otherwise furnished in writing to the Company by or on behalf of any Underwriter for use in any Preliminary Prospectus or the Registration Statement or the Prospectus or any such amendment thereof or supplement thereto, and (2) the indemnity agreement contained in this paragraph (a) with respect to any Preliminary Prospectus shall not inure to the benefit of any Underwriter from whom the person asserting any such losses, claims, damages, liabilities or expenses purchased the Stock which is the subject thereof (or to the benefit of any person controlling such Underwriter) if at or prior to the written confirmation of the sale of such Stock a copy of the Prospectus (or the Prospectus as amended or supplemented) was not sent or delivered to such person and the untrue statement or omission of a material fact contained in such Preliminary Prospectus was corrected in the Prospectus (or the Prospectus as amended or supplemented) unless the failure is the result of noncompliance by the Company with paragraph (c) of Section 6 hereof. The indemnity agreements of the Company contained in this paragraph (a) and the representations and warranties of the Company contained in Section 2 hereof shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any indemnified party and shall survive the delivery of and payment for the Stock. (b) Each Underwriter severally agrees to indemnify and hold harmless the Company, each of its officers who signs the Registration Statement on his own behalf or pursuant to a power of attorney, each of its directors, each other Underwriter and each person (including each partner or officer thereof) who controls the Company or any such other Underwriter within the meaning of Section 15 of the Securities Act, from and against any and all losses, claims, damages or liabilities, joint or several, to which such indemnified parties or any of them may become subject under the Securities Act, the Exchange Act, or the common law or otherwise and to reimburse each of them for any legal or other expenses (including, except as otherwise hereinafter provided, reasonable fees and disbursements of counsel) incurred by the respective indemnified parties in connection with defending against any such losses, claims, damages or liabilities or in connection with any investigation or inquiry of, or other proceeding which may be brought against, the respective indemnified parties, in each case arising out of or based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (including the Prospectus as part thereof and any Rule 462(b) registration statement) or any post-effective amendment thereto (including any Rule 462(b) registration statement) or 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 or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (as amended or as supplemented if the Company shall have filed with the Commission any amendment thereof or supplement thereto) or the omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, if such statement or omission was made in reliance upon and in conformity with information furnished as herein stated or otherwise furnished in writing to the Company by or on behalf of such indemnifying Underwriter for use in the Registration Statement or the Prospectus or any such amendment thereof or supplement thereto. The indemnity agreement of each Underwriter contained in this paragraph (b) shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any indemnified party and shall survive the delivery of and payment for the Stock. (c) Each party indemnified under the provision of paragraphs (a) and (b) of this Section 7 agrees that, upon the service of a summons or other initial legal process upon it in any action or suit instituted against it or upon its receipt of written notification of the commencement of any investigation or inquiry of, or proceeding against, it in respect of which indemnity may be sought on account of any indemnity agreement contained in such paragraphs, it will promptly give written notice (herein called the Notice) of such service or notification to the party or parties from whom indemnification may be sought hereunder. No indemnification provided for in such paragraphs shall be available to any party who shall fail so to give the Notice if the party to whom such Notice was not given was unaware of the action, suit, investigation, inquiry or proceeding to which the Notice would have related and was prejudiced by the failure to give the Notice, but the omission so to notify such indemnifying party or parties of any such service or notification shall not relieve such indemnifying party or parties from any liability which it or they may have to the indemnified party for contribution or otherwise than on account of such indemnity agreement. Any indemnifying party shall be entitled at its own expense to participate in the defense of any action, suit or proceeding against, or investigation or inquiry of, an indemnified party. Any indemnifying party shall be entitled, if it so elects within a reasonable time after receipt of the Notice by giving written notice (herein called the Notice of Defense) to the indemnified party, to assume (alone or in conjunction with any other indemnifying party or parties) the entire 11 defense of such action, suit, investigation, inquiry or proceeding, in which event such defense shall be conducted, at the expense of the indemnifying party or parties, by counsel chosen by such indemnifying party or parties and reasonably satisfactory to the indemnified party or parties; PROVIDED, HOWEVER, that (i) if the indemnified party or parties reasonably determine that there may be a conflict between the positions of the indemnifying party or parties and of the indemnified party or parties in conducting the defense of such action, suit, investigation, inquiry or proceeding or that there may be legal defenses available to such indemnified party or parties different from or in addition to those available to the indemnifying party or parties, then counsel for the indemnified party or parties shall be entitled to conduct the defense to the extent reasonably determined by such counsel to be necessary to protect the interests of the indemnified party or parties and (ii) in any event, the indemnified party or parties shall be entitled to have counsel chosen by such indemnified party or parties participate in, but not conduct, the defense. If, within a reasonable time after receipt of the Notice, an indemnifying party gives a Notice of Defense and the counsel chosen by the indemnifying party or parties is reasonably satisfactory to the indemnified party or parties, the indemnifying party or parties will not be liable under paragraphs (a) through (c) of this Section 7 for any legal or other expenses subsequently incurred by the indemnified party or parties in connection with the defense of the action, suit, investigation, inquiry or proceeding, except that (A) the indemnifying party or parties shall bear the legal and other expenses incurred in connection with the conduct of the defense as referred to in clause (i) of the proviso to the preceding sentence and (B) the indemnifying party or parties shall bear such other expenses as it or they have authorized to be incurred by the indemnified party or parties. If, within a reasonable time after receipt of the Notice, no Notice of Defense has been given, the indemnifying party or parties shall be responsible for any legal or other expenses incurred by the indemnified party or parties in connection with the defense of the action, suit, investigation, inquiry or proceeding. (d) If the indemnification provided for in this Section 7 is unavailable or insufficient to hold harmless an indemnified party under paragraph (a) or (b) of this Section 7, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in paragraph (a) or (b) of this Section 7 (i) in such proportion as is appropriate to reflect the relative benefits received by each indemnifying party from the offering of the Stock 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 each indemnifying party in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, or actions in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Stock received by the Company and the total underwriting discount received by the Underwriters, as set forth in the table on the cover page of the Prospectus, bear to the aggregate public offering price of the Stock. Relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by each indemnifying party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The parties agree that it would not be just and equitable if contributions pursuant to this paragraph (d) were to be 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 into account the equitable considerations referred to in the first sentence of this paragraph (d). The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities, or actions in respect thereof, referred to in the first sentence of this paragraph (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigation, preparing to defend or defending against any action or claim which is the subject of this paragraph (d). Notwithstanding the provisions of this paragraph (d), no Underwriter shall be required to contribute any amount in excess of the underwriting discount applicable to the Stock purchased by such Underwriter. 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 in this paragraph (d) to contribute are several in proportion to their respective underwriting obligations and not joint. 12 Each party entitled to contribution agrees that upon the service of a summons or other initial legal process upon it in any action instituted against it in respect of which contribution may be sought, it will promptly give written notice of such service to the party or parties from whom contribution may be sought, but the omission so to notify such party or parties of any such service shall not relieve the party from whom contribution may be sought from any obligation it may have hereunder or otherwise (except as specifically provided in paragraph (c) of this Section 7). (e) The Company will not, without the prior written consent of each Underwriter, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action, suit or proceeding in respect of which indemnification may be sought hereunder (whether or not such Underwriter or any person who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act is a party to such claim, action, suit or proceeding) unless such settlement, compromise or consent includes an unconditional release of such Underwriter and each such controlling person from all liability arising out of such claim, action, suit or proceeding. 8. TERMINATION. This Agreement may be terminated by you at any time prior to the Closing Date by giving written notice to the Company if after the date of this Agreement trading in the Common Stock shall have been suspended, or if there shall have occurred (i) the engagement in hostilities or an escalation of major hostilities by the United States or the declaration of war or a national emergency by the United States on or after the date hereof, (ii) any outbreak of hostilities or other national or international calamity or crisis or change in economic or political conditions if the effect of such outbreak, calamity, crisis or change in economic or political conditions in the financial markets of the United States would, in the Underwriters' reasonable judgment, make the offering or delivery of the Stock impracticable, (iii) suspension of trading in securities generally or a material adverse decline in value of securities generally on the New York Stock Exchange, the American Stock Exchange, or The Nasdaq Stock Market, or limitations on prices (other than limitations on hours or numbers of days of trading) for securities on either such exchange or system, (iv) the enactment, publication, decree or other promulgation of any federal or state statute, regulation, rule or order of, or commencement of any proceeding or investigation by, any court, legislative body, agency or other governmental authority which in the Underwriters' reasonable opinion materially and adversely affects or will materially and adversely affect the business or operations of the Company, (v) declaration of a banking moratorium by either federal or New York State authorities or (vi) the taking of any action by any federal, state or local government or agency in respect of its monetary or fiscal affairs which in the Underwriters' reasonable opinion has a material adverse effect on the securities markets in the United States. If this Agreement shall be terminated pursuant to this Section 8, there shall be no liability of the Company to the Underwriters and no liability of the Underwriters to the Company; PROVIDED, HOWEVER, that in the event of any such termination the Company agrees to indemnify and hold harmless the Underwriters from all costs or expenses incident to the performance of the obligations of the Company under this Agreement, including all costs and expenses referred to in paragraphs (i) and (j) of Section 6 hereof. 9.

(c) You shall have received from Fenwick & West LLP, counsel for the Company, an opinion, addressed to the Underwriters and dated the Closing Date, covering the matters set forth in Annex A hereto, and if Option Stock is 13 purchased at any date after the Closing Date, an additional opinion from such counsel, addressed to the Underwriters and dated such later date, confirming that the statements expressed as of the Closing Date in such opinion remain valid as of such later date. (d) You shall be satisfied that (i) as of the Effective Date, the statements made in the Registration Statement and the Prospectus were true and correct and neither the Registration Statement nor the Prospectus omitted to state any material fact required to be stated therein or necessary in order to make the statements therein, respectively, not misleading, (ii) since the Effective Date, no event has occurred which should have been set forth in a supplement or amendment to the Prospectus which has not been set forth in such a supplement or amendment, (iii) since the respective dates as of which information is given in the Registration Statement in the form in which it originally became effective and the Prospectus contained therein, there has not been any material adverse change or any development involving a prospective material adverse change in or affecting the business, properties, financial condition or results of operations of the Company, whether or not arising from transactions in the ordinary course of business, and, since such dates, except in the ordinary course of business.

(e) You shall have received on the Closing Date and on any later date on which Option Stock is purchased a certificate, dated the Closing Date or such later date, as the case may be, and signed by the President and the Chief Financial Officer of the Company, stating that the respective signers of said certificate have carefully examined the Registration Statement in the form in which it originally became effective and the Prospectus contained therein and any supplements or amendments thereto, and that the statements included in clauses (i) through (vii) of paragraph (d) of this Section 9 are true and correct. (f) You shall have received from Ernst & Young LLP a letter or letters addressed to the Underwriters and dated the Closing Date and any later date on which Option Stock is purchased, confirming that they are independent public accountants with respect to the Company within the meaning of the Securities Act and the applicable published rules and regulations thereunder and based upon the procedures described in their letter delivered to you concurrently with the execution of this Agreement (herein called the Original Letter), but carried out to a date not more than three business days prior to the Closing Date or such later date on which Option Stock is purchased (i) confirming, to the extent true, that the statements and conclusions set forth in the Original Letter are accurate as of the Closing Date or such later date, as the case may be, and (ii) setting forth any revisions and additions to the statements and conclusions set forth in the Original Letter which are necessary to reflect any changes in the facts described in the Original Letter since the date of the Original Letter or to reflect the availability of more recent financial statements, data or information. The letters shall not disclose any change, or any development involving a prospective change, in or affecting the business or properties of the Company (or any of its subsidiaries) which, in your sole judgment, makes it impractical or inadvisable to proceed with the public offering of the Stock or the purchase of the Option Stock as contemplated by the Prospectus.

(ii) as of the closing of the sale of the Underwritten Stock and assuming the filing of the Second Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware, the authorized capital stock of the Company consists of 5,000,000 shares of Preferred Stock, $0.001 pare value, of which, to our knowledge, there are no shares outstanding, and 100,000,000 shares of Common Stock, $0.001 par value, of which, to our knowledge there are outstanding _________________ shares (including the Underwritten Stock issued on the date hereof);
