Immersion Corporation, a Delaware corporation (herein called the Company), proposes to issue and sell _______ shares of its authorized but unissued Common Stock, $0.001 par value (herein called the Common Stock) (said shares of Common Stock being herein called the Underwritten Stock). The Company and the stockholders of the Company named in Schedule II hereto (herein collectively called the Selling Securityholders) propose to grant to the Underwriters (as hereinafter defined) an option to purchase up to additional shares of Common Stock (herein called the Option Stock and with the Underwritten Stock herein collectively called the Stock). The Common Stock is more fully described in the Registration Statement and the Prospectus hereinafter mentioned.

The Company and the Selling Securityholders severally hereby confirm the agreements made with respect to the purchase of the Stock by the several underwriters, for whom you are acting, named in Schedule I hereto (herein collectively called the Underwriters, which term shall also include any underwriter purchasing Stock pursuant to Section 3(b) hereof). You represent and warrant that you have been authorized by each of the other Underwriters to enter into this Agreement on its behalf and to act for it in the manner herein provided.

1. REGISTRATION STATEMENT. The Company has filed with the Securities and Exchange Commission (herein called the Commission) a registration statement on Form S-1 (No. 33-_____), including the related preliminary prospectus, for the registration under the Securities Act of 1933, as amended (herein called the Securities Act) of the Stock. Copies of such registration statement and of each amendment thereto, if any, including the related preliminary prospectus (meeting the requirements of Rule 430A of the rules and regulations of the Commission) heretofore filed by the Company with the Commission have been delivered to you.

The term Prospectus as used in this Agreement shall mean the prospectus relating to the Stock first filed with the Commission pursuant to Rule 424(b) and Rule 430A (or if no such filing is required, as included in the Registration Statement) and, in the event of any supplement or amendment to such prospectus after the Effective Date, shall also mean (from and after the filing with the Commission of such supplement or the effectiveness of such amendment) such prospectus as so supplemented or amended. The term Preliminary Prospectus as used in this Agreement shall mean each preliminary prospectus included in such registration statement prior to the time it becomes effective.

The Registration Statement has been declared effective under the Securities Act, and no post-effective amendment to the Registration Statement has been filed as of the date of this Agreement. The Company has caused to be delivered to you copies of each Preliminary Prospectus and has consented to the use of such copies for the purposes permitted by the Securities Act.

(i) Such Selling Securityholder has good and marketable title to all the shares of Stock to be sold by such Selling Securityholder hereunder, free and clear of all liens, encumbrances, equities, security interests and claims whatsoever, with full right and authority to deliver the same hereunder, subject, in the case of such Selling Securityholder, to the rights of degrees , as custodian (herein called the Custodian), and that upon the delivery of and payment for such shares of the Stock hereunder, the several Underwriters will receive good and marketable title thereto, free and clear of all liens, encumbrances, equities, security interests and claims whatsoever.

(iii) All consents, approvals, authorizations and orders required for the execution and delivery by such Selling Securityholder of the Custody Agreement and Power of Attorney, the execution and delivery by or on behalf of such Selling Securityholder of this Agreement and the sale and delivery of the shares of Stock to be sold by such Selling Securityholder under this Agreement have been obtained and are in full force and effect; such Selling Securityholder, if other than a natural person, has been duly organized and is validly existing in good standing under the laws of the jurisdiction of its organization as the type of entity that it purports to be; and such Selling Securityholder has full legal right, power and authority to enter into and perform its obligations under this Agreement and such Custody Agreement and Power of Attorney, and to sell, assign, transfer and deliver the Stock to be sold by such Selling Securityholder under this Agreement.

[ADD ADDITIONAL REPS OF SELLING SECURITYHOLDERS]

3. PURCHASE OF THE STOCK BY THE UNDERWRITERS.

(a) On the basis of the representations and warranties and subject to the terms and conditions herein set forth, the Company agrees to issue and sell shares of the Underwritten Stock to the several Underwriters and each of the Underwriters agrees to purchase from the Company the respective aggregate number of shares of Underwritten Stock set forth opposite its name in Schedule I. The price at which such shares of Underwritten Stock shall be sold by the Company and purchased by the several Underwriters shall be $___ per share. In making this Agreement, each Underwriter is contracting severally and not jointly; except as provided in paragraphs (b) and (c) of this Section 3, the agreement of each Underwriter is to purchase only the respective number of shares of the Underwritten Stock specified in Schedule I.

(b) If for any reason one or more of the Underwriters shall fail or refuse (otherwise than for a reason sufficient to justify the termination of this Agreement under the provisions of Section 8 or 9 hereof) to purchase and pay for the number of shares of the Stock agreed to be purchased by such Underwriter or Underwriters, the Company shall immediately give notice thereof to you, and the non-defaulting Underwriters shall have the right within 24 hours after the receipt by you of such notice 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 or Underwriters and upon the terms herein set forth, all or any part of the shares of the Stock which such defaulting Underwriter or Underwriters agreed to purchase. If the non-defaulting Underwriters fail so to make such arrangements with respect to all such shares and portion, the number of shares of the Stock which each 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 which the defaulting Underwriter or Underwriters agreed to purchase; provided, however, that the non-defaulting Underwriters shall not be obligated to purchase the shares and portion which the defaulting Underwriter or Underwriters agreed to purchase if the aggregate number of such shares of the Stock exceeds 10% of the total number of shares of the Stock which all Underwriters agreed to purchase hereunder. If the total number of shares of the Stock which the defaulting Underwriter or Underwriters 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 above referred to, to make arrangements with other underwriters or purchasers 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 and the Selling Securityholders shall have the right to postpone the Closing Date determined as provided in Section 5 hereof for not more than seven 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 neither the non-defaulting Underwriters nor the Company and the Selling Securityholders shall make arrangements within the 24-hour periods stated above for the purchase of all the shares of the Stock which the

defaulting Underwriter or Underwriters agreed to purchase hereunder, this Agreement shall be terminated without further act or deed and without any liability on the part of the Company or the Selling Securityholders to any non-defaulting Underwriter and without any liability on the part of any non-defaulting Underwriter to the Company or the Selling Securityholders. Nothing in this paragraph (b), and no action taken hereunder, shall relieve any 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 and the Selling Securityholders grant an option to the several Underwriters to purchase, severally and not jointly, up to shares in the aggregate of the Option Stock from the Company and the Selling Securityholders at the same price per share as the Underwriters shall pay for the Underwritten Stock. 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 thirtieth day after the date of this Agreement upon written or telegraphic notice by you to the Company setting forth the aggregate number of shares of the Option Stock as to which the several Underwriters are exercising the option. Delivery of certificates for the shares of Option Stock, and payment therefor, shall be made as provided in Section 5 hereof. The number of shares of the Option Stock to be purchased by each Underwriter shall be the same percentage of the total number of shares of the Option Stock to be purchased by the several Underwriters as such Underwriter is purchasing of the Underwritten Stock, as adjusted by you in such manner as you deem advisable to avoid fractional shares. The number of shares of Option Stock to be sold by each Selling Securityholder is set forth in Schedule II opposite the name of each Selling Securityholder.

4. OFFERING BY UNDERWRITERS.

(a) The terms of the initial public offering by the Underwriters of the Stock 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 in the ______, _______ and ______ paragraphs under "Underwriting" in the Registration Statement, any Preliminary Prospectus and the Prospectus (insofar as such information relates to the Underwriters) 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 respective Underwriters represent and warrant to the Company that the statements made therein are correct.

5. DELIVERY OF AND PAYMENT FOR THE STOCK.

(a) Delivery of certificates for the shares of the Underwritten Stock and the Option Stock (if the option granted by Section 3(c) hereof shall have been exercised not later than 7:00 A.M., San Francisco time, on the date two business days preceding the Closing Date), and payment therefor, shall be made at the office of Gray Cary Ware & Freidenrich LLP, 400 Hamilton Avenue, Palo Alto, California 94301-1825, at 7:00 a.m., San Francisco time, on the fourth business day after the date of this Agreement, or at such time on such other day, not later than seven full business days after such fourth business day, as shall be agreed upon in writing by the Company, you and (if Option Stock is to be delivered) the Selling Securityholders. The date and hour of such delivery and payment (which may be postponed as provided in Section 3(b) hereof) are herein called the Closing Date.

(b) If the option granted by Section 3(c) hereof shall be exercised after 7:00 a.m., San Francisco time, on the date two business days preceding the Closing Date, delivery of certificates for the shares of Option Stock, and payment therefor, shall be made at the office of Gray Cary Ware & Freidenrich LLP, 400 Hamilton Avenue, Palo Alto, California 94301-1825, at 7:00 a.m., San Francisco time, on the third business day after the exercise of such option.

(c) Payment for the Stock purchased from the Company shall be made to the Company or its order, and payment for the Stock purchased from the Selling Securityholders shall be made to the Custodian, for the account of the Selling Securityholders, in each case by one or more certified or official bank check or checks or by wire, in either case in same day funds. Such payment shall be made upon delivery of certificates for the Stock to you for the respective accounts of the several Underwriters against receipt therefor signed by you. Certificates for the Stock to be delivered to you shall be registered in such 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 the Option Stock. Such certificates will be made available to the Underwriters for inspection, checking and packaging at the offices of Lewco Securities Corporation, 2 Broadway, New York, New York 10004 on the business day prior to the Closing Date or, in the case of the Option Stock, by 3:00 p.m., New York time, on the business day preceding the date of purchase.

It is understood that you, individually and not on behalf of the Underwriters, may (but shall not be obligated to) make payment to the Company and the Selling Securityholders for shares to be purchased by any Underwriter whose check shall not have been received by you on the Closing Date or any later date on which Option Stock is purchased for the account of such Underwriter. Any such payment by you shall not relieve such Underwriter from any of its obligations hereunder.

6. FURTHER AGREEMENTS OF THE COMPANY AND THE SELLING SECURITYHOLDERS. Each of the Company and the Selling Securityholders (where expressly indicated) respectively 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 any amendment to the Registration Statement or supplement to the Prospectus of which you shall not previously have been advised and furnished with a copy or to which you shall have reasonably objected in writing or which is not in compliance with the Securities Act or the rules and regulations of the Commission.

(b) The Company will promptly notify each Underwriter in the event of (i) the request by the Commission for amendment of the Registration Statement or for supplement to the Prospectus or for any additional information, (ii) the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, (iii) the institution or notice of intended institution of any action or proceeding for that purpose, (iv) the receipt by the Company of any notification with respect to the suspension of the qualification of the Stock for sale in any jurisdiction, or (v) the receipt by it of notice of the initiation or threatening of any proceeding for such purpose. The Company and the Selling Securityholders will make every reasonable effort to prevent the issuance of such a stop order and, if such an order shall at any time be issued, to obtain the withdrawal thereof at the earliest possible moment.

(c) The Company will (i) on or before the Closing Date, deliver to you a signed copy of the Registration Statement as originally filed and of each amendment thereto filed prior to the time the Registration Statement becomes effective and, promptly upon the filing thereof, a signed copy of each post-effective amendment, if any, to the Registration Statement (together with, in each case, all exhibits thereto unless previously furnished to you) and will also deliver to you, for distribution to the Underwriters, a sufficient number of additional conformed copies of each of the foregoing (but without exhibits) so that one copy of each may be distributed to each Underwriter, (ii) as promptly as possible deliver to you and send to the several Underwriters, at such office or offices as you may designate, as many copies of the Prospectus as you may reasonably request, and (iii) thereafter from time to time during the period in which a prospectus is required by law to be delivered by an Underwriter or dealer, likewise send to the Underwriters as many additional copies of the Prospectus and as many copies of any supplement to the Prospectus and of any amended prospectus, filed by the Company with the Commission, as you may reasonably request for the purposes contemplated by the Securities Act.

(d) If at any time during the period in which a prospectus is required by law to be delivered by an Underwriter or dealer any event relating to or affecting the Company, or of which the Company shall be advised in writing by you, shall occur as a result of which it is necessary, in the opinion of counsel for the Company or of counsel for the Underwriters, to supplement or amend the Prospectus in order to make the Prospectus not misleading in the light of the circumstances existing at the time it is delivered to a purchaser of the Stock, the Company will forthwith prepare and file with the Commission a supplement to the Prospectus or an amended prospectus so that the Prospectus as so supplemented or amended will not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances existing at the time such Prospectus is delivered to such purchaser, not misleading. If, after the initial public offering of the Stock by the Underwriters and during such period, the Underwriters shall propose to vary the terms of 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 Stock may be sold by the several Underwriters to use the Prospectus, as from time to time amended or supplemented, in connection with the sale of the Stock in accordance with the applicable provisions of the Securities Act and the applicable rules and regulations thereunder for such period.

(e) Prior to the filing thereof with the Commission, the Company will submit to you, for your information, a copy of any post-effective amendment to the Registration Statement and any supplement to the Prospectus or any amended prospectus proposed to be filed.

(f) The Company will cooperate, when and as requested by you, in the qualification of the Stock for offer and sale under the securities or blue sky laws of such jurisdictions as you may designate and, during the period in which a prospectus is required by law to be delivered by an Underwriter or dealer, in keeping such qualifications in good standing under said securities or blue sky laws; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation in any jurisdiction in which it is not so qualified. 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 and the Selling Securityholders jointly and severally agree to pay all costs and expenses incident to the performance of their obligations under this Agreement, including all costs and expenses incident to (i) the preparation, printing and filing with the Commission and the National Association of Securities Dealers, Inc.

(k) The provisions of paragraphs (i) and (j) of this Section are intended to relieve the Underwriters from the payment of the expenses and costs which the Company and the Selling Securityholders hereby agree to pay and shall not affect any agreement which the Company and the Selling Securityholders may make, or may have made, for the sharing of any such expenses and costs.

(l) The Company and each of the Selling Securityholders hereby agrees that, without the prior written consent of Hambrecht & Quist LLC on behalf of the Underwriters, the Company or such Selling Securityholder, as the case may be, will not, for a period of 180 days following the commencement of the public offering of the Stock by the Underwriters, 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 the Stock to be sold to the Underwriters pursuant to this Agreement. The obligations of the Company under this subsection (l) also shall not apply to (A) shares of Common Stock issued by the Company upon the exercise of options granted under the stock option plans of the Company (the "Option Plans") or upon the exercise of warrants outstanding as of the date hereof, all as described in the introduction to the table under the caption "Capitalization" in the Preliminary Prospectus, (B) options to purchase Common Stock granted under the Option Plans, and (C) shares of Common Stock issued by the Company under its employee stock purchase plan.

such person or entity will not, for a period of 180 days following the commencement of the public offering of the Stock by the Underwriters, 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 Company will not release any of its officers, directors or other stockholders from any lock-up agreements currently existing or hereafter effected without the prior written consent of Hambrecht & Quist LLC.

(n) 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.

(o) The Company is familiar with the Investment Company Act of 1940, as amended, 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 and the Selling Securityholders jointly and severally agree 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 and the Selling Securityholders jointly and severally agree 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 and the Selling Securityholders contained in this paragraph (a) shall not apply to any such losses, claims, damages, liabilities or 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, (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, and (3) each Class III Selling Securityholder shall only be liable under this paragraph with respect to (A) information pertaining to such Selling Securityholder furnished by or on behalf of such Selling Securityholder expressly for use in any Preliminary Prospectus or the Registration Statement or the Prospectus or any such amendment thereof or supplement thereto or (B) facts that would constitute a breach of any representation or warranty of such Selling Securityholder set forth in Section 2(b) hereof. The indemnity agreements of the Company and the Selling Securityholders contained in this paragraph (a) and the representations and warranties of the Company and the Selling Securityholders 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, and the Selling Securityholders 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 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 and the Selling Securityholders 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 Selling Securityholders 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.

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) Neither the Company nor the Selling Securityholders will, 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.

(f) The liability of each Selling Securityholder under the indemnity and reimbursement agreements contained in the provisions of this Section 7 and
Section 11 hereof shall be limited to an amount equal to the initial public offering price of the stock sold by such Selling Securityholder to the Underwriters less underwriting discounts and commissions. The Company and the Selling Securityholders may agree, as among themselves and without limiting the rights of the Underwriters under this Agreement, as to the respective amounts of such liability for which they each shall be responsible.

8. TERMINATION. This Agreement may be terminated by you at any time prior to the Closing Date by giving written notice to the Company and the Selling Securityholders 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 or 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 or the Selling Securityholders to the Underwriters and no liability of the Underwriters to the Company or the Selling Securityholders; provided, however, that in the event of any such termination the Company and the Selling Securityholders agree to indemnify and hold harmless the Underwriters from all costs or expenses incident to the performance of the obligations of the Company and the Selling Securityholders under this Agreement, including all costs and expenses referred to in paragraphs (i) and (j) of Section 6 hereof.

9. CONDITIONS OF UNDERWRITERS' OBLIGATIONS.

(c) You shall have received from Gray Cary Ware & Freidenrich, counsel for the Company and the Selling Securityholders, and from Hickman, Stephens & Coleman LLP, patent counsel for the Company, opinions, addressed to the Underwriters and dated the Closing Date, covering the matters set forth in Annex A and Annex B hereto, respectively, and if Option Stock is purchased at any date after the Closing Date, additional opinions from each such counsel, addressed to the Underwriters and dated such later date, confirming that the statements expressed as of the Closing Date in such opinions 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 in all material respects 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 and its subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business, and, since such dates, except in the ordinary course of business, neither the Company nor any of its subsidiaries has entered into any material transaction not referred to in the Registration Statement in the form in which it originally became effective and the Prospectus contained therein, (iv) neither the Company nor any of its subsidiaries has any material contingent obligations which are not disclosed in the Registration Statement and the Prospectus, (v) there are not any pending or known threatened legal proceedings to which the Company or any of its subsidiaries is a party or of which property of the Company or any of its subsidiaries is the subject which are material and which are not disclosed in the Registration Statement and the Prospectus, (vi) there are not any franchises, contracts, leases or other documents which are required to be filed as exhibits to the Registration Statement which have not been filed as required, (vii) the representations and warranties of the Company herein are true and correct in all material respects as of the Closing Date or any later date on which Option Stock is to be purchased, as the case may be, and
(viii) there has not been any material change in the market for securities in general or in political, financial or economic conditions from those reasonably foreseeable as to render it impracticable in your reasonable judgment to make a public offering of the Stock, or a material adverse change in market levels for securities in general (or those of companies in particular) or financial or economic conditions which render it inadvisable to proceed.

(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

(g) You shall have received from Deloitte & Touche LLP a letter stating that their review of the Company's system of internal accounting controls, to the extent they deemed necessary in establishing the scope of their examination of the Company's financial statements as at , 1999, did not disclose any weakness in internal controls that they considered to be material weaknesses.

All the agreements, opinions, certificates and letters mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if Fenwick & West LLP, counsel for the Underwriters, shall be satisfied that they comply in form and scope.

In case any of the conditions specified in this Section 9 shall not be fulfilled, this Agreement may be terminated by you by giving notice to the Company and to the Selling Securityholders.
