(a) Neither the Commission nor any state securities commission has issued any order preventing or suspending the use of any Preliminary Prospectus or has instituted or threatened to institute any proceedings with respect to such an order. The Registration Statement and the Prospectus comply, and on the Closing Date (as hereinafter defined) and any later date on which the Option Stock is to be purchased, the Prospectus will comply, in all material respects, with the provisions of the Securities Act and the rules and regulations of the Commission thereunder (the "Securities Act and Rules"). On the Effective Date, the Registration Statement did not contain any untrue statement of a material fact and did not omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading, and on the Effective Date the Prospectus did not, and on the Closing Date and any later date on which the Option Stock is to be purchased, will not, contain any untrue statement of a material fact and did not omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that none of the representations and warranties in this subparagraph 2(a) shall apply to statements in, or omissions from, the Registration Statement or the Prospectus made in reliance upon and in conformity with information herein or otherwise furnished in writing to the Company by or on behalf of the Underwriters expressly for use in the Registration Statement or Prospectus.

(b) Each of the Company and its subsidiaries (i) has been duly incorporated and is validly existing as a corporation in good standing under the laws of its jurisdiction of incorporation, having full power and corporate authority to own or lease its properties and to conduct its business as described in the Registration Statement and the Prospectus; and (ii) is duly qualified to do business as a foreign corporation and is in good standing in all jurisdictions in which the character of the property owned or leased or the nature of the business transacted by it makes qualification

necessary (except where the failure to be so qualified would not have a material adverse effect on the business, management, properties, assets, rights, condition (financial or otherwise) or results of operations of the Company and its subsidiaries, taken as a whole). The Company has employees located solely in California, Nevada, Michigan and Washington, and in no other jurisdiction in the United States, and is duly qualified to do business as a foreign corporation and is in good standing in California, Massachusetts and Nevada, which are the only jurisdictions where the Company is required to be so qualified. Each subsidiary of the Company is not currently conducting any business and is not required to be qualified to do business in any jurisdiction. The Company and its subsidiaries do not own any capital stock or other equity securities in any other entity, except for instruments or interests held by the Company or its subsidiaries solely for investment.

(c) The Company has the duly authorized and validly issued outstanding capitalization as of [ , 2004] set forth under the caption "Capitalization" in the Prospectus and will have the adjusted capitalization as of [ , 2004] (giving effect to the closing of the offering contemplated by this Agreement) set forth therein on the Closing Date and any later date on which the Option Stock is to be purchased, based on the assumptions set forth therein. The securities of the Company conform to the descriptions thereof contained in the Registration Statement and the Prospectus.

The outstanding shares of the Company's capital stock have been duly authorized and validly issued by the Company and are fully paid and nonassessable and were issued in transactions that were exempt from the registration requirements of the Securities Act, without violation of any preemptive rights, rights of first refusal or similar rights. Except as created hereby or otherwise described in the Registration Statement and the Prospectus, there are no outstanding options, warrants, rights or other arrangements requiring the Company at any time to issue any capital stock. No holders of outstanding shares of capital stock of the Company are entitled as such to any preemptive or other rights to subscribe for any of the Shares to be sold by the Company, and neither the filing of the Registration Statement nor the offering or sale of the Shares to be sold by the Company as contemplated by this Agreement gives rise to any rights, other than those that have lapsed or have been waived or satisfied, for or relating to, the registration of any securities of the Company. Except as described in the Prospectus, 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 Shares registered pursuant to the Registration Statement. The Shares to be sold by the Company are duly authorized, and will be, when sold to the Underwriters as provided herein, validly issued, fully paid and nonassessable and conform to the description thereof contained in the section of the Registration Statement and the Prospectus entitled "Description of Capital Stock." No further approval or authority of the stockholders or the Board of Directors of the Company will be required for the issuance and sale of the Shares to be sold by the Company as contemplated herein.

Each such contractual restriction is hereinafter referred to as a "Company Lock-Up." For the avoidance of doubt, the term "Company

Lock-Up" shall include, but not be limited to, the provisions contained in [Section 2.13] of that certain Amended and Restated Investor Rights Agreement dated as of [February [ ], 2004], by and among the Company and the Investors and Common Shareholders, as defined therein.

(d) The Company has full legal right, power and authority to enter into this Agreement and to consummate the transactions provided for herein. This Agreement has been duly authorized, executed and delivered by the Company and, assuming it is a binding agreement of the Underwriters, constitutes a legal, valid and binding agreement of the Company enforceable against the Company in accordance with its terms (except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other laws of general application relating to or affecting the enforcement of creditors' rights and the application of equitable principles relating to the availability of remedies and except as rights to indemnity or contribution may be limited by federal or state securities laws and the public policy underlying such laws), and none of the Company's execution or delivery of this Agreement, its performance and compliance hereunder, its consummation of the transactions contemplated herein, its application of the net proceeds of the offering in the manner set forth under the caption "Use of Proceeds" or the conduct of its business as described in the Registration Statement and the Prospectus, conflicts or will conflict with or results or will result in any breach or violation of any of the terms or provisions of, or constitutes or will constitute a default under, causes or will cause (or permits or will permit) the maturation or acceleration of any liability or obligation or the termination of any right under, or results or will result in the creation or imposition of any lien, charge or encumbrance upon, any property or assets of the Company or any of its subsidiaries pursuant to the terms of (i) the certificate of incorporation or bylaws of the Company or any of its subsidiaries; (ii) any indenture, mortgage, deed of trust, voting trust agreement, stockholders' agreement, note agreement or other agreement or instrument to which either the Company or any of its subsidiaries is a party or by which it is bound or to which its respective property is subject; or (iii) any statute, judgment, decree, order, rule or regulation applicable to the Company or any of its subsidiaries of any government, arbitrator, court, regulatory body or administrative agency or other governmental agency or body, domestic or foreign, having jurisdiction over the Company or any of its subsidiaries or their activities or properties.

(m) All executed agreements or copies of executed agreements filed or incorporated by reference as exhibits to the Registration Statement have been duly and validly authorized, executed and delivered by the Company or such subsidiary and constitute the legal, valid and binding agreements of the Company or such subsidiary enforceable by and against it in accordance with their respective terms (except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization or other similar laws relating to enforcement of creditors' rights generally, and general equitable principles relating to the availability of remedies, and except as rights to indemnity or contribution may be limited by federal or state securities laws and the public policy underlying such laws).

(s) The Company and its subsidiaries are conducting their businesses in compliance with all applicable laws, ordinances or governmental rules or regulations of the jurisdictions in which they are conducting business, except where the failure to be so in compliance would not materially and adversely affect the business, management, properties, assets, rights, condition (financial or otherwise) or results of operations of the Company and its subsidiaries, taken as a whole.

The Company has valid and enforceable leases for the properties described in the Registration Statement and the Prospectus as leased by it, free and clear of all liens, encumbrances, security interests, equities, claims and defects, except such as are not material and do not interfere with the use made by the Company and its subsidiaries thereof and except as disclosed in the Registration Statement and the Prospectus.

(b) If for any reason one of the Underwriters shall fail or refuse (other than for a reason sufficient to justify the termination of this Agreement under the provisions of Section 7 or 12 hereof) to purchase and pay for the number of Shares agreed to be purchased by such Underwriter, the non-defaulting Underwriters shall have the right within 24 hours after the receipt by you of notice of such failure or refusal to so purchase, to purchase or procure one or more other Underwriters to purchase, in such proportions as may be agreed upon between you and such purchasing Underwriter and upon the terms herein set forth, all or any part of the Shares that such defaulting Underwriter agreed to purchase. If a non-defaulting Underwriter fails so to make such arrangements with respect to all such Shares and portion, the number of Shares that such

non-defaulting Underwriter is otherwise obligated to purchase under this Agreement shall be automatically increased on a pro rata basis to absorb the remaining Shares and portion that the defaulting Underwriter agreed to purchase; provided, however, that such non-defaulting Underwriter shall not be obligated to purchase the Shares and portion that such defaulting Underwriter agreed to purchase if the aggregate number of such Shares exceeds 10% of the total number of Shares that the Underwriters agreed to purchase under this Agreement. If the total number of Shares that the defaulting Underwriter agreed to purchase shall not be purchased or absorbed in accordance with the two preceding sentences, the Company shall have the right, within 24 hours next succeeding the 24-hour period referred to above, to make arrangements with other underwriters or purchasers reasonably satisfactory to you for purchase of such Shares and portion on the terms herein set forth. In any such case, either you or the Company shall have the right to postpone the Closing Date determined as provided in Section 5 hereof for not more than seven (7) business days after the date originally fixed as the Closing Date pursuant to said Section 5 in order that any necessary changes in the Registration Statement, the Prospectus or any other documents or arrangements may be made. If such non-defaulting Underwriter or the Company does not make arrangements (such arrangements being subject to the Underwriters' approval, which shall not be unreasonably withheld) within the 24-hour periods stated above for the purchase of all the Shares that such defaulting Underwriter agreed to purchase hereunder, this Agreement shall be terminated without further act or deed and without any liability on the part of the Company to the non-defaulting Underwriter or on the part of the non-defaulting Underwriter to the Company. Nothing in this paragraph 3(b), and no action taken hereunder, shall relieve a defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

(c) On the basis of the representations, warranties and covenants herein contained, and subject to the terms and conditions herein set forth, the Company grants an option to the Underwriters to purchase, severally and not jointly, the Option Stock at the Purchase Price. Said option may be exercised only to cover over-allotments in the sale of the Underwritten Stock by the Underwriters and may be exercised in whole or in part at any time (but not more than once) on or before the 30^th day after the date of this Agreement upon written or electronic notice by the Underwriters to the Company setting forth the aggregate number of shares of Option Stock as to which the Underwriters are exercising the option. Delivery of the certificates for the shares of Option Stock, and payment therefor, shall be made as provided in Section 5 hereof. The number of shares of Option Stock to be purchased by each Underwriter shall be in such amounts as the Underwriters shall agree upon prior to the exercise of the option set forth herein.

4. Offering by the Underwriters.

(a) The terms of the initial public offering by the Underwriters of the Shares to be purchased by them shall be as set forth in the Prospectus. The Underwriters may from time to time change the public offering price after the closing of the initial public offering and increase or decrease the concessions and discounts to dealers as they may determine.

(b) The information set forth under the caption "Plan of Distribution" in the Registration Statement, any Preliminary Prospectus and the Prospectus relating to the Shares filed by the Company (insofar as such information relates to the Underwriters or related persons) constitutes the only information furnished by the Underwriters to the Company for inclusion in the Registration Statement, any Preliminary Prospectus and the Prospectus, and you, on behalf of the Underwriters, severally and not jointly, represent and warrant to the Company that the statements made therein (insofar as they relate to the Underwriters or related persons) are correct and do not omit any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

5. Delivery of and Payment for the Shares.

Certificates for the Shares to be delivered to you shall be registered in the name or names and shall be in such denominations as you may request at least one business day before the Closing Date, in the case of Underwritten Stock, and at least one business day prior to the purchase thereof, in the case of Option Stock. Such certificates will be made available to the Underwriters for inspection, checking and packaging on the business day preceding the Closing Date or, in the case of Option Stock, by 12:00 P.M., Pacific Standard Time, on the business day preceding the date of purchase.

6. Covenants of the Company. The Company covenants and agrees as follows:

(a) The Company will (i) prepare and timely file with the Commission under Rule 424(b) a Prospectus containing information previously omitted at the time of effectiveness of the Registration Statement in reliance on Rule 430A; and (ii) not file with the Commission any amendment to the Registration Statement or supplement to the Prospectus (A) of which the Underwriters shall not previously have been advised and furnished with a copy a reasonable period of time prior to the proposed filing and as to which filing the Underwriters shall not have given their consent or (B) which is not in compliance with the Securities Act and the Rules.

(b) As soon as the Company is advised or obtains knowledge thereof, the Company will advise the Underwriters promptly (i) of any request made by the Commission for amendment of the Registration Statement, for supplement to the Prospectus or for additional information; (ii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, or the institution or threat of any action, investigation or proceeding for that purpose; or (iii) the receipt by the Company of any notification with respect to the suspension of the qualification of the Shares for sale in any jurisdiction, or the receipt by it of notice of the initiation or threatening of any proceeding for that purpose.

If, after the initial public offering of the Shares by the Underwriters and during such period, the Underwriters shall propose to vary the terms of the offering thereof by reason of changes in general market conditions or otherwise, you will advise the Company in writing of the proposed variation, and, if in the opinion either of counsel for the Company or of counsel for the Underwriters such proposed variation requires that the Prospectus be supplemented or amended, the Company will forthwith prepare and file with the Commission a supplement to the Prospectus or an amended prospectus setting forth such variation. The Company authorizes the Underwriters and all dealers to whom any of the Shares may be sold by the Underwriters to use the Prospectus, as from time to time amended or supplemented, in connection with the sale of the Shares in accordance with the applicable provisions of the Securities Act and Rules for such period.

(a) Subject to the provisions of paragraph (d) of this Section 9, the Company agrees to indemnify and hold harmless each Underwriter (and any person participating in the distribution who is deemed to be an underwriter (as defined in Section 2(11) of the Securities Act) and each person (including each member or officer thereof), if any, who controls any Underwriter or such person deemed to be an underwriter (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act), from and against any and all losses, claims, damages or liabilities, joint or several (and actions in respect thereof), to which such indemnified parties or any of them may become subject, under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, and the Company agrees to reimburse each such Underwriter or any other such indemnified party and each such officer, director and controlling person for any legal or other expenses (including, except as otherwise hereinafter provided, reasonable fees and disbursements of counsel) as 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 that may be brought against, the respective indemnified parties, in each case arising out of or that are based upon (i) any untrue statement or alleged untrue statement of any 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, (ii) any untrue statement or alleged untrue statement of any 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 required to be stated therein or necessary to make the statements therein, in light of the circumstance under which they were made, not misleading, and (iii) any untrue statement or alleged untrue statement of any material fact contained in any audio or visual materials provided by the Company or based upon written information furnished by or on behalf of the Company including, without limitation, slides, videos, films or tape recordings, used in connection with the marketing of the Shares, including without limitation, any untrue or alleged untrue statements communicated to securities analysts employed by the Underwriters; provided, however, that (A) the indemnity agreement of the Company contained in this paragraph (a) shall not apply to any such loss, claim, damage, liability or action if such statement or omission was made in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Underwriter expressly for use in any Preliminary Prospectus or the Registration Statement or the Prospectus or any such amendment thereof or supplement thereto and (B) the indemnity agreement contained in this paragraph (a) with respect to any Preliminary Prospectus shall not

inure to the benefit of any Underwriter (or such persons) if the person asserting any such loss, claim, damage, liability or action purchased Shares that are the subject thereof to the extent that any such loss, claim, damage, liability or action (1) results from the fact that such Underwriter (or such persons) failed to send or give a copy of the Prospectus (as amended or supplemented) to such person at or prior to the confirmation of the sale of such Shares to such person in any case where such delivery is required by the Securities Act and (2) arises out of or is based upon an untrue statement or omission of a material fact contained in such Preliminary Prospectus that was corrected in the Prospectus (as amended and supplemented), unless such failure resulted from non-compliance 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 and payment for the Shares.

(b) Subject to the provisions of paragraph (d) of this Section 9, each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who has signed the Registration Statement, each person, if any, who controls the Company (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act), and the other Underwriters 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 other federal or state statutory law or regulation, at 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 that may be brought against, the respective indemnified parties, in each case arising out of or are based upon (i) any untrue statement or alleged untrue statement of any 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 any 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 required to be stated therein or necessary to make the statements therein, in light of the circumstance under which they were made, not misleading, in each case to the extent, but only to the extent, that such statement or omission was made in reliance upon and in conformity with information furnished in writing by or on behalf of such indemnifying Underwriter to the Company expressly for use in the Registration Statement or the Prospectus or any such amendment thereof or supplement thereto, and will reimburse, as incurred, any reasonable legal or other expenses incurred (including, except as otherwise hereinafter provided, reasonable fees and disbursements of counsel) by the Company or any such director, officer or controlling person in connection with investigating or defending any such loss, claim, damage, liability or action. 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 and payment for the Shares.

(c) Each party indemnified under the provisions of paragraph (a) or (b) of this Section 9 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, such indemnified party will

promptly notify any party or parties from whom indemnification may be sought hereunder of the commencement thereof in writing. No indemnification provided for in such paragraphs shall be available to any party who shall fail to give such notice if the party to whom such notice was not given was unaware of the action, suit, investigation, inquiry or proceeding to which such notice would have related and was prejudiced by the failure to give the notice, but the omission to notify such indemnifying party or parties of any such service or notification shall not relieve such indemnifying party or parties from any liability that it or they may have to the indemnified party for contribution or otherwise than on account of such indemnity agreement. Any indemnifying party or parties against which a claim is to be made will be entitled, at its own expense, to participate in the defense of such action, suit, investigation or inquiry of, an indemnified party. Any indemnifying party shall be entitled, if it so elects within a reasonable time after receipt of notice from the indemnified party or parties of an action, suit, investigation or inquiry to which indemnity may be sought, to assume the entire defense thereof (alone or in conjunction with any other indemnifying party or parties), at its own expense, in which case such defense shall be conducted by counsel reasonably satisfactory to the indemnified party or parties; provided, however, that (i) if the indemnified party or parties has reasonably concluded 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 such 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. Upon receipt of notice from the indemnifying party to such indemnified party of its election so 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 9 for any legal or other expenses (other than the reasonable costs of investigation) subsequently incurred by such indemnified party in connection with the defense thereof unless (A) the indemnified party has employed such counsel in connection with the assumption of different or additional legal defenses in accordance with the proviso to the immediately preceding sentence; or (B) the indemnifying party has authorized in writing the employment of counsel for the indemnified party at the expense of the indemnifying party. If no such notice to assume the defense of such action has been given within a reasonable time of the indemnified party's or parties' notice to such indemnifying party or parties, the indemnifying party or parties shall be responsible for any and all 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 9 is unavailable or insufficient to hold harmless an indemnified party under paragraph (a) or (b) above in respect of any losses, claims, damages, expenses or liabilities (or actions in respect thereof) referred to therein, 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 such losses, claims, damages or liabilities (or actions in respect thereof) referred to in paragraphs (a) and (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by each of the contributing parties from the offering of the Shares; 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 of the contributing parties, on the one hand, and the party to be indemnified, on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, 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 proportion as the total net proceeds from the offering of the Shares (after deducting the underwriting discount but before deducting expenses) and the total underwriting discount received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus, bear to the aggregate public offering price of the Shares. 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 the 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 or by any other method of allocation that does not take into account the equitable consideration referred to above. The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this paragraph (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this paragraph (d), no Underwriter shall be required to contribute any amount in excess of the underwriting discount applicable to the Shares purchased by such Underwriter hereunder. 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.

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 to which a claim for contribution may be made against another party or parties under this paragraph (d), it will promptly notify such party or parties from whom contribution may be sought, but the omission to notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any other obligation it may have hereunder or otherwise (except as specifically provided in paragraph (c) of this Section 9). The contribution agreement set forth above shall be in addition to any liabilities that any indemnifying party may have at common law or otherwise.

(e) No indemnifying party will, without the prior written consent of the indemnified party, 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 indemnified party 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 indemnified party and each such controlling person from all liability arising out of such claim, action, suit or proceeding.

10. Reimbursement of Certain Expenses. In addition to its other obligations under Section 9 of this Agreement, the Company hereby agrees to reimburse on a quarterly basis the Underwriters for all reasonable legal and other expenses incurred in connection with investigating or defending any claim, action, investigation, inquiry or other proceeding arising out of or based upon any statement or omission, or any alleged statement or omission, described in paragraph (a) of Section 9 of this Agreement, notwithstanding the absence of a judicial determination as to the propriety and enforceability of the obligations under this Section 10 and the possibility that such payments might later be held to be improper; provided, however, that (i) to the extent that any such payment is ultimately held to be improper, the Underwriters shall promptly refund it; and (ii) the Underwriters shall, severally and not jointly, provide to the Company, upon request, reasonable assurances of their ability to effect any refund, when and if due.

11. Representations, etc. to Survive Delivery. The respective representations, warranties, agreements, covenants, indemnities and statements of, and on behalf of, the Company, its subsidiaries and its officers and the Underwriters, respectively, set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Underwriters, and will survive delivery of and payment for the Shares. Any successors to the Underwriters shall be entitled to the indemnity, contribution and reimbursement agreements contained in this Agreement.

12. Termination.

(a) In addition to the termination described in Section 7 hereof, this Agreement (except for the provisions of Section 9 hereof) may be terminated by you by notice to the Company at any time prior to the Closing Date if: (i) the Company shall have sustained a loss by strike, fire, flood, accident or other calamity of such a character as to interfere materially with the conduct of the business and operations of the Company regardless of whether or not such loss was insured; (ii) trading in the Common Stock shall have been suspended or trading in securities generally on the New York Stock Exchange, the American Stock Exchange or the Nasdaq National Market shall have been suspended, or limitations on such trading shall have been imposed or limitations on prices shall have been established on any such exchange or market system; (iii) an escalation of major hostilities or international conflict involving the United States or the declaration of war or a national emergency by the United States on or after the date hereof shall have occurred; (iv) any outbreak of hostilities, act of terrorism or other national or international calamity or crisis or material adverse change in economic or political conditions shall have occurred if the effect of such outbreak, terrorist act, calamity, crisis or change in economic or political conditions in the financial markets of the United States would, in your judgment, make the offering or delivery of the Shares impracticable; (v) 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 shall have occurred that in the Underwriters' opinion materially and adversely affects or will materially or adversely affect the business or operations of the Company; (vi) a banking moratorium shall have been declared by New York or United States authorities; or (vii) the taking of any action by any federal, state or local government or agency in respect of its monetary or fiscal affairs shall have occurred that in your judgment has a material adverse effect on, or will materially and adversely affect, the securities markets in the United States.

(b) If this Agreement is terminated pursuant to this Section 12, 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 expenses incident to the performance of the obligations of the Company under this Agreement, including all costs and expenses referred to in paragraph (g) of Section 6. Notwithstanding any termination of this Agreement, the provisions of Section 9 hereof shall survive and remain in full force and effect.

Exhibit A

Form of Opinion of Fenwick & West LLP on Behalf of the Company

(a) Each of the Company and its subsidiaries is duly incorporated and is validly existing as a corporation in good standing under the laws of its jurisdiction of incorporation with full power and authority (corporate and other) to own or lease its properties and to conduct its business as described in the Registration Statement and the Prospectus and is duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction in which the ownership or leasing of property or the conduct of its business requires such qualification (except for the following jurisdictions: [list], in which the failure so to qualify would not have a material adverse effect on the Company and its subsidiaries taken as a whole).

(b) The authorized capital stock of the Company consists of [ ] shares of Preferred Stock, $ [ ] par value, of which there are no outstanding shares, and [ ] shares of Common Stock, $ [ ] par value, of which there are outstanding [ ] shares (including the Underwritten Stock and any shares of Option Stock issued on the date hereof). The securities of the Company conform in all material respects to the description thereof contained in the Prospectus. Proper corporate proceedings have been validly taken to authorize the Company's authorized capital stock and all outstanding shares of such capital stock (including the Underwritten Stock and the shares of Option Stock issued, if any) have been duly authorized and validly issued by the Company, are fully paid and nonassessable and have been issued in compliance with all federal and state securities laws. Any Option Stock purchased after the Closing Date, when issued and delivered to and paid for by the Underwriters as provided in the Underwriting Agreement, will have been duly and validly issued and be fully paid and nonassessable. No preemptive rights, rights of first refusal or other rights exist with respect to the Shares, or the issue and sale thereof, pursuant to the Company's certificate of incorporation or bylaws, and there are no contractual preemptive rights that have not been waived, right of first refusal or rights of co-sale that exist with respect to the Shares.

(c) The outstanding shares of capital stock or ownership interests of each of the Company's subsidiaries have been duly authorized and validly issued, are fully paid and non-assessable, and are solely owned by the Company free and clear of all liens, encumbrances and equities and claims; and no options, warrants or other rights to purchase, agreements or other obligations to issue or other rights to convert any obligations into shares of capital stock or ownership interests in such subsidiary are outstanding.

(d) The Company does not own any interest in or control, directly or indirectly, any other corporation, association or other entity other than the subsidiaries set forth in the Registration Statement.

(e) There are no rights of any holders of the Company's securities, not effectively satisfied or waived, to require registration under the Securities Act of any of the Company's securities or other securities of the Company in connection with the filing of the Registration Statement or with the offer or sale of the Shares.

(f) There are no rights of any holders of the Company's securities to require the Company to register any securities under the Securities Act that are not described in the Registration Statement and the Prospectus.

(g) The Company has full legal right, power and authority to enter into the Underwriting Agreement and to consummate the transactions provided for therein. The Underwriting Agreement has been duly authorized, executed and delivered by the Company and constitutes the legal, valid and binding agreement of the Company, enforceable in accordance with its terms, except as limited by applicable bankruptcy, insolvency, reorganization, moratorium or other laws

now or hereafter in effect relating to or affecting creditors' rights generally or by general principles of equity relating to the availability of remedies and except as rights to indemnity and contribution may be limited by federal or state securities laws or the public policy underlying such laws.

(h) None of the Company's execution or delivery of the Underwriting Agreement, its performance thereof, its consummation of the transactions contemplated therein or its application of the net proceeds of the offering in the manner set forth under the caption "Use of Proceeds," conflicts or will conflict with or results or will result in any breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon, any property or assets of the Company pursuant to the terms of the certificate of incorporation or bylaws of the Company or any of its subsidiaries; the terms of any indenture, mortgage, deed of trust, voting trust agreement, stockholder's agreement, note agreement or other agreement or instrument known to such counsel after reasonable investigation to which the Company or any of its subsidiaries is a party or by which it is or may be bound or to which its properties may be subject; any statute, rule or regulation of any regulatory body or administrative agency or other governmental agency or body, domestic or foreign, having jurisdiction over the Company, any of its subsidiaries or any of their activities or properties; or any judgment, decree or order, known to such counsel after reasonable investigation, of any government, arbitrator, court, regulatory body or administrative agency or other governmental agency or body, domestic or foreign, having such jurisdiction.

(j) To the knowledge of such counsel, the conduct of the business of the Company and its subsidiaries is not in violation of any federal, state or local statute, administrative regulation or other law, which violation is likely to have a material adverse effect on the Company and its subsidiaries, taken as a whole, and each of the Company and its subsidiaries has obtained all licenses, permits, franchises, certificates and other authorizations from state, federal and other regulatory authorities as are necessary or required for the ownership, leasing and operation of its properties and the conduct of its business as presently conducted and as contemplated in the Prospectus.

(k) The Registration Statement is effective under the Securities Act; any required filing of the Prospectus pursuant to Rule 424(b) has been made in the manner and within the time period required by Rule 424(b); and no stop order suspending the effectiveness of the Registration Statement or any amendment thereto has been issued, and no proceedings for that purpose have been instituted or are pending or, to the knowledge of such counsel, are threatened or contemplated by the Commission.

(l) The Registration Statement and the Prospectus (except for the financial statements, schedules and other financial data included therein, as to which such counsel need not express any opinion), comply as to form in all material respects with the requirements of the Securities Act and Rules.

(m) The descriptions contained and summarized in the Registration Statement and the Prospectus of franchises, contracts, leases, documents, or any threatened legal or governmental actions, suits or proceedings, are accurate and fairly represent in all material respects the information required to be shown by the Securities Act and Rules. There are no franchises, contracts, leases, documents, or any threatened legal or governmental actions, suits or proceedings,

which are required by the Securities Act and Rules to be described in the Registration Statement or the Prospectus or to be filed as exhibits to the Registration Statement that are not described or filed as required.

(n) The statements (i) in the Prospectus under the captions "Risk Factors"; "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources" "Business—Technology infrastructure and our website" and "Business—Intellectual Property"; "Business—Legal Proceedings"; "Management"; "Certain Relationships and Related Transactions"; "Description of Capital Stock"; and "Shares Eligible for Future Sale" and (ii) in the Registration Statement in Items 14 and 15; in each case insofar as such statements constitute summaries of the legal matters, documents or proceedings referred to therein, fairly present the information required under the Securities Act and Rules with respect to such legal matters, documents and proceedings and fairly summarize the matters referred to therein to the extent required by the Securities Act and Rules at the time the Registration Statement became effective, and did not contain any untrue statement of material fact or omit to state a material fact to be stated therein or necessary to make the statements therein not misleading.

(o) Neither the Company nor any of its subsidiaries is, and will not be, after giving effect to the issuance and sale of the Shares, an "investment company" or a "company" controlled by an "investment company" within the meaning of such term under the Investment Company Act of 1940, as amended, and the rules and regulations of the Commission promulgated thereunder.

(p) To such counsel's knowledge, there is no legal or governmental proceedings pending or threatened to which the Company or any of its subsidiaries is a party or to which any of the properties of the Company or any of its subsidiaries is subject that are required to be described in the Registration Statement or the Prospectus and are not so described, and there is no statute, regulation, contract or other document that is required to be described in the Registration Statement or the Prospectus or to be filed as an exhibit to the Registration Statement that is not described or filed as required.
