Through December 31, 2000, the Company shall maintain term life insurance upon the life of each of the Founders in the amount of $500,000 each, with the proceeds payable to the Company. A certificate evidencing such insurance shall be attached to this Agreement as EXHIBIT F. (e) NONDISCLOSURE AGREEMENTS. The Company will require all persons now or 13 <PAGE> 14 hereafter employed by the Company who have access to confidential and proprietary information of the Company to enter into agreements containing (i) nondisclosure and assignment of invention provisions substantially similar to those set forth in EXHIBIT E, and, subject to the discretion of the Board of Directors of the Company, noncompetition provisions substantially similar to those set forth in EXHIBIT E. (f) RIGHT OF FIRST REFUSAL. (i) The Company hereby grants to each Purchaser, each Prior Purchaser and each Founder (collectively, the "RIGHTHOLDERS") a right of first refusal to purchase, on a pro rata basis, all or any part of New Securities (as defined below) which the Company may, from time to time, propose to sell and issue, subject to the terms and conditions set forth below. A Rightholder's pro rata share, for purposes of this subsection 7(f), shall equal a fraction, the numerator of which is the number of shares of capital stock of the Company owned by such Rightholder and the denominator of which is the total number of shares of capital stock of the Company owned by all of the Rightholders. (ii) "NEW SECURITIES" shall mean any capital stock of the Company whether now authorized or not, and rights, options or warrants to purchase capital stock, and securities of any type whatsoever which are, or may become, convertible into capital stock; PROVIDED, HOWEVER, that the term "New Securities" does not include (A) the Shares issuable under this Agreement (including any amendment hereto) or the shares of Common Stock issuable upon conversion of the Series A Preferred, Series B Preferred, Series C Preferred or Series D Preferred; (B) securities offered to the public pursuant to a Registration Statement (as defined in subsection 8(a)); (C) securities issued for the acquisition of another corporation by the Company by merger, purchase of substantially all the assets of such corporation or other reorganization resulting in the ownership by the Company of not less than 51% of the voting power of such corporation; (D) shares of Common Stock issued to employees or consultants of the Company pursuant to the Company's 1994 Stock Option Plan, as amended, in an amount not in excess of the Plan Pool, as defined below; (E) securities issued upon the exercise of currently outstanding warrants issued by the Company; or (F) securities issued as a result of any stock split, stock dividend or reclassification of Common Stock, distributable on a pro rata basis to all holders of Common Stock. As used herein, the term "Plan Pool" means a number of shares of Common Stock, as adjusted for stock splits, stock dividends and similar recapitalizations, equal to the sum of (1) 1,175,000 shares plus (2) the greater of (x) 1,500,000 shares or (y) 20% of the aggregate number of shares of Series D Preferred sold hereunder. (iii) In the event the Company intends to issue New Securities, it shall give each Rightholder written notice of such intention, describing the type of New Securities to be issued, the price thereof and the general terms upon which the Company proposes to effect such issuance. Each Rightholder shall have 30 days from the date of any such notice to agree to purchase all or part of its or his pro rata share of such New Securities for the price and upon the 14 <PAGE> 15 general terms and conditions specified in the Company's notice by giving written notice to the Company stating the quantity of New Securities to be so purchased. Each Rightholder shall have a right of overallotment such that if any Rightholder fails to exercise his or its right hereunder to purchase his or its total pro rata portion of New Securities, the other Rightholders may purchase such portion on a pro rata basis, by giving written notice to the Company within five days from the date that the Company provides written notice to the other Rightholders of the amount of New Securities with respect to which such nonpurchasing Rightholder has failed to exercise its or his right hereunder. (iv) In the event any Rightholder fails to exercise the foregoing right of first refusal with respect to any New Securities within such 30-day period (or the additional five-day period provided for overallotments), the Company may within 120 days thereafter sell any or all of such New Securities not agreed to be purchased by the Rightholders, at a price and upon general terms no more favorable to the purchasers thereof than specified in the notice given to each Rightholder pursuant to paragraph (c) above. In the event the Company has not sold such New Securities within such 120-day period, the Company shall not thereafter issue or sell any New Securities without first offering such New Securities to the Rightholders in the manner provided above. (v) For purposes of this subsection 7(f), "Rightholder" shall include the general partners, officers or other affiliates of a Purchaser, and a Purchaser may apportion its pro rata share among itself and such general partners, officers and other affiliates in such proportions as it deems appropriate; provided that the pro rata share ownership of a Rightholder shall be determined solely on the basis of the number of shares of capital stock of the Company owned by such Rightholder and shall not be increased by the share holdings of any affiliate of such Rightholder. (g) NEGATIVE COVENANTS. Notwithstanding any other provision of this Agreement, without (i) the prior written consent of the holders of at least 60% of the outstanding shares of Preferred Stock, or (ii) solely with respect to clauses (v), (vi) and (viii) below, the approval at a duly held Board meeting of directors and/or observers representing the holders of at least 60% of the outstanding shares of Preferred Stock, the Company shall not, nor shall any of the Founders cause the Company to: (i) merge or consolidate with any other corporation or purchase or own any stock or other securities of or interest in any other corporation, partnership or other entity (other than U.S. government or U.S. government-backed securities purchased by the Company pending expenditure of cash) or, except in the ordinary course of business, sell, lease, license or otherwise dispose of any portion of its properties or assets to any party, including without limitation any intellectual property; (ii) effect any reverse stock split, stock combination, reclassification or 15 <PAGE> 16 similar event; (iii) amend or repeal its Certificate of Incorporation or By-Laws; (iv) except as permitted under this Agreement, the Certificate of Incorporation or any agreement contemplated hereby, authorize, create, issue, reclassify, repurchase or redeem any stock or other security of the Company, or issue, grant, or, authorize any option, warrant or other right respecting any stock or other security of the Company, provided, that such consent shall not be required for the issuance of any option or right under the Company's 1994 Stock Option Plan, as amended, or any other stock option or stock purchase plan duly established by the Company, or for the purchase of any Common Stock upon the exercise of an option or right issued under such a plan; (v) make any loan or advance, other than trade credit on terms approved by two-thirds (2/3) of the Board of Directors or partial payments on capital expenditures approved by two-thirds (2/3) of the Board of Directors, to any person or entity except for advances and similar expenditures in an outstanding amount not to exceed $25,000 in the aggregate at any time; (vi) enter into any marketing, distribution, sales or other "corporate partnering" agreement or plan which grants a third party exclusive or substantial rights to market, sell, supply or manufacture the Company's products or services; or, except as approved by a majority of the Board of Directors of the Company, purchase, lease, license or otherwise acquire from others any tangible or intangible property other than in the ordinary course of business; (vii) dissolve, liquidate or suspend all or any part of its business, or file any petition, or institute any proceeding, or be subject to any petition or proceeding filed against it that is not dismissed within thirty (30) days after filing, under the Federal Bankruptcy Code or under any state law relating to insolvency, receivership, reorganization or debt adjustment; (viii) have outstanding trade payables in an amount in excess of $1,500,000, have outstanding trade payables more than 90 days old in an amount in excess of $250,000, or incur, create, assume or otherwise become primarily or secondarily liable with respect to, or absolutely or contingently liable with respect to, or permit to exist, any other indebtedness, including without limitation lease financing, which is in an aggregate amount in excess of $250,000; provided that such consent or approval shall be required for any lease which calls for aggregate payments in excess of $250,000 and for any guaranty of indebtedness by the Company, regardless of amount; (ix) establish or modify any stock option or stock purchase plan of the Company; or 16 <PAGE> 17 (x) increase or decrease the authorized number of directors constituting the Board of Directors. While it is not the desire of the Purchasers or Prior Purchasers to direct the day-to-day management of the Company's affairs, the Purchasers and Prior Purchasers are making a substantial investment in the Company and have a justified interest in ensuring consensus with respect to the conduct of all material aspects of the Company's business. The covenants set forth in this subsection are not intended to impede actions by the Board of Directors in the ordinary course of business so long as such actions are not likely to have a material adverse impact on the Purchasers or Prior Purchasers. Each Purchaser and Prior Purchaser shall respond promptly and, in any event, within 15 days to any request for a consent under this subsection. The Company may in its discretion in connection with requests for consent to any transaction pursuant to this Subsection, (i) describe such transaction by means of a summary of the terms thereof rather than by providing copies of applicable contracts and (ii) withhold the name or names of the other party or parties to the transaction. (h) INTERNATIONAL INVESTMENT AND TRADE IN SERVICES SURVEY ACT. The Company shall use its best efforts to file on a timely basis all reports required to be filed by it under 22 U.S.C. Section 3104, or any similar statute, relating to a foreign person's direct or indirect investment in the Company. (i) QUALIFIED SMALL BUSINESS STOCK. The Company shall submit to its stockholders (including the Purchasers and Prior Purchasers) and to the Internal Revenue Service any reports that may be required under Section 1202(d)(1)(C) of the Code and the Regulations promulgated thereunder. In addition, within ten business days after any Purchaser's or Prior Purchaser's written request therefor, the Company shall deliver to such Purchaser or Prior Purchaser a written statement indicating whether such Purchaser's or Prior Purchaser's interest in the Company constitutes "qualified small business stock" as defined in Section 1202(c) of the Code. (j) SMALL BUSINESS. The Company shall submit such reports and provide such assistance as may reasonably be required by any Purchaser or Prior Purchaser which is a "small business investment company" under the Small Business Investment Act of 1958 and the Regulations promulgated thereunder. (k) TERMINATION OF COVENANTS. Unless earlier terminated, the covenants contained in this Section 7 shall terminate, and be of no further force or effect, upon the effectiveness of a Registration Statement (as defined in subsection 8(a) covering the Company's first bona fide firm commitment public offering of Common Stock, resulting in gross proceeds to the Company of at least $25,000,000, at a price per share of at least $10.00 (as adjusted for stock splits, stock dividends, recapitalizations and similar events). 17 <PAGE> 18 8.

"EXCHANGE ACT" means the Securities Exchange Act of 1934, as amended, or any similar Federal statute, and the rules and regulations of the Commission issued under such Act, as they each may, from time to time, be in effect. "REGISTRATION STATEMENT" means a registration statement filed by the Company with the Commission for a public offering and sale of Securities of the Company (other than a registration statement on Form S-8 or Form S-4, or their successors, or any other form for a limited purpose, or any registration statement covering only Securities proposed to be issued in exchange for Securities or assets of another corporation). "REGISTRATION EXPENSES" means the expenses described in subsection 8(f). "REGISTRABLE SHARES" means (i) the shares of Common Stock issued or issuable upon conversion of the Preferred Stock, (ii) shares of Common Stock issued or issuable upon the exercise of currently outstanding warrants issued by the Company, (iii) any shares of Common Stock of the Company acquired by the Purchasers or Prior Purchasers pursuant to subsection 7(f) hereof, and (iv) any other shares of Common Stock of the Company issued in respect of such shares (because of stock splits, stock dividends, reclassifications, recapitalizations, or similar events); PROVIDED, HOWEVER, that shares of Common Stock which are Registrable Shares shall cease to be Registrable Shares upon any sale pursuant to a Registration Statement, Section 4(1) of the Securities Act or Rule 144 under the Securities Act, or any sale in any manner to a person or entity which, by virtue of Section 10 of this Agreement, is not entitled to the rights provided by this Section 8. Wherever reference is made in this Agreement to a request or consent of holders of a certain percentage of Registrable Shares, the determination of such percentage shall include shares of Common Stock issuable upon conversion of the Shares even if such conversion has not yet been effected. "SECURITIES ACT" means the Securities Act of 1933, as amended, or any similar Federal statute, and the rules and regulations of the Commission issued under such Act, as they each may, from time to time, be in effect. "SHARES" shall have the meaning specified in subsection 1(b). 18 <PAGE> 19 "STOCKHOLDERS" means the Purchasers and Prior Purchasers and any persons or entities to whom the rights granted under this Section 8 are transferred by any Purchasers or Prior Purchasers or their respective successors or assigns pursuant to Section 10 hereof. (b) SALE OR TRANSFER OF SHARES; LEGEND. (i) The Shares and the Registrable Shares and shares issued in respect of the Shares or the Registrable Shares shall not be sold or transferred unless either (A) they first shall have been registered under the Securities Act, or (B) the Company first shall have been furnished with an opinion of legal counsel, reasonably satisfactory to the Company, to the effect that such sale or transfer is exempt from the registration requirements of the Securities Act. (ii) Notwithstanding the foregoing, no registration or opinion of counsel shall be required for a transfer by a Purchaser or Prior Purchaser to any person or entity which directly or indirectly holds an interest in the Purchaser or Prior Purchaser or a partner of any purchaser, or in connection with a bona fide reorganization, if the transferee agrees in writing to be subject to the terms of this Section 8 to the same extent as if he were an original Purchaser or Prior Purchaser hereunder. (iii) Each certificate or other instrument representing the Shares and the Registrable Shares and shares issued in respect of the Shares or the Registrable Shares shall bear a legend substantially in the following form: "The Securities represented by this instrument have not been registered under the Securities Act of 1933, as amended, and may not be offered, sold or otherwise transferred, pledged or hypothecated unless and until such shares are registered under such Act or an opinion of counsel satisfactory to the Company is obtained to the effect that such registration is not required." The foregoing legend shall be removed from the certificates representing any Registrable Shares, at the request of the holder thereof, at such time as they become eligible for resale pursuant to Rule 144(k) under the Securities Act. (iv) The Company shall, at all times during which it is neither subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, nor exempt from reporting pursuant to Rule 12g3-2(b) under the Exchange Act, upon the written request of any Purchaser or Prior Purchaser, provide in writing to such Purchaser or Prior Purchaser and to any prospective transferee of any Shares or Registrable Shares of such Purchaser or Prior Purchaser the information concerning the Company described in Rule 144A(d)(4) under the Securities Act ("RULE 144A INFORMATION"). The Company also shall, upon the written request of any Purchaser or Prior Purchaser, cooperate with and assist such Purchaser or Prior Purchaser or any member of 19 <PAGE> 20 the National Association of Securities Dealers, Inc. PORTAL system in applying to designate and thereafter maintain the eligibility of the Shares or Registrable Shares for trading through PORTAL. The Company's obligations under this Section 8(b) (iv) shall at all times be contingent upon receipt from the prospective transferee of Shares or Registrable Shares of a written agreement to take all reasonable precautions to safeguard the Rule 144A Information from disclosure to anyone other than persons who will assist such transferee in evaluating the purchase of any Shares or Registrable Shares. (c) REQUIRED REGISTRATIONS. (i) At any time after the earlier of December 31, 2002, or the closing of the Company's first underwritten public offering of shares of Common Stock pursuant to a Registration Statement, a Stockholder or Stockholders holding in the aggregate at least 35% of the Registrable Shares may request, in writing, that the Company effect the registration on Form S-1 or Form S-2 (or any successor form) of Registrable Shares owned by such Stockholder or Stockholders having an aggregate offering price of at least $5,000,000 (based on the then current market price or fair value). If the holders initiating the registration intend to distribute the Registrable Shares by means of an underwriting, they shall so advise the Company in their request. In the event such registration is underwritten, the right of other Stockholders to participate shall be conditioned on such Stockholders' participation in such underwriting. Upon receipt of any such request, the Company shall promptly give written notice of such proposed registration to all Stockholders. Such Stockholders shall have the right, by giving written notice to the Company within 30 days after the Company provides its notice, to elect to have included in such registration such of their Registrable Shares as such Stockholders may request in such notice of election, subject to the approval of the underwriter managing the offering. Thereupon, the Company shall, as expeditiously as possible, use its best efforts to effect the registration, on Form S-1 or Form S-2 (or any successor form), of all Registrable Shares which the Company has been requested to so register. (ii) At any time after the Company becomes eligible to file a Registration Statement on Form S-3 (or any successor form relating to secondary offerings), a Stockholder or Stockholders holding in the aggregate at least 25% of the Registrable Shares may request the Company, in writing, to effect the registration on Form S-3 (or such successor form), of Registrable Shares having an aggregate offering price of at least $2,500,000 (based on the current public market price). Upon receipt of any such request, the Company shall promptly give written notice of such proposed registration to all Stockholders. Such Stockholders shall have the right, by giving written notice to the Company within 30 days after the Company provides its notice, to elect to have included in such registration such of their Registrable Shares as such Stockholders may request in such notice of election. Thereupon, the Company shall, as expeditiously as possible, use its best efforts to effect the registration on Form S-3, or such successor form, of all Registrable Shares which the Company has been requested to register. 20 <PAGE> 21 (iii) The Company shall not be required to effect more than three registrations pursuant to paragraph (i) above or more than four registrations pursuant to paragraph (ii) above. In addition, the Company shall not be required to effect any registration (other than on Form S-3 or any successor form relating to secondary offerings) within six months after the effective date of any other Registration Statement of the Company. (iv) If at the time of any request to register Registrable Shares pursuant to this subsection 8(c), the Company is engaged or has fixed plans to engage within 30 days of the time of the request in a registered public offering as to which the Stockholders may include Registrable Shares pursuant to subsection 8(d) or is engaged in any other activity which, in the good faith determination of the Company's Board of Directors, would be adversely affected by the requested registration to the material detriment of the Company, then the Company may at its option direct that such request be delayed for a period not in excess of six months from the effective date of such offering or the date of commencement of such other material activity, as the case may be, such right to delay a request to be exercised by the Company not more than once in any two-year period. (d) INCIDENTAL REGISTRATION. (i) Whenever the Company proposes to file a Registration Statement (other than pursuant to subsection 8(c) at any time and from time to time, it will, prior to such filing, give written notice to all Stockholders of its intention to do so and, upon the written request of a Stockholder or Stockholders given within 20 days after the Company provides such notice (which request shall state the intended method of disposition of such Registrable Shares), the Company shall use its best efforts to cause all Registrable Shares which the Company has been requested by such Stockholder or Stockholders to register to be registered under the Securities Act to the extent necessary to permit their sale or other disposition in accordance with the intended methods of distribution specified in the request of such Stockholder or Stockholders; provided that the Company shall have the right to postpone or withdraw any registration effected pursuant to this subsection 8(d) without Obligation to any Stockholder. (ii) In connection with any offering under this subsection 8(d) involving an underwriting, the Company shall not be required to include any Registrable Shares in such underwriting unless the holders thereof accept the terms of the underwriting as agreed upon between the Company and the underwriters selected by it, and then only in such quantity as will not, in the opinion of the underwriters, jeopardize the success of the offering by the Company. If in the opinion of the managing underwriter the registration of all, or part of, the Registrable Shares which the holders have requested to be included would materially and adversely affect such public offering, then the Company shall be required to include in the underwriting only that number of Registrable Shares, if any, which the managing underwriter believes may be sold without causing such adverse effect. If the number of Registrable Shares to be included in the underwriting in accordance with the foregoing is less than the total number of 21 <PAGE> 22 shares which the holders of Registrable Shares have requested to be included, then the holders of Registrable Shares who have requested registration and other holders of shares of Common Stock entitled to include shares of Common Stock in such registration shall participate in the underwriting pro rata based upon their total ownership of shares of Common Stock of the Company. If any holder would thus be entitled to include more shares than such holder requested to be registered, the excess shall be allocated among other requesting holders pro rata based upon their total ownership of Registrable Shares. (e) REGISTRATION PROCEDURES. If and whenever the Company is required by the provisions of this Agreement to use its best efforts to effect the registration of any of the Registrable Shares under the Securities Act, the Company shall: (i) file with the Commission a Registration Statement with respect to such Registrable Shares and use its best efforts to cause that Registration Statement to become and remain effective; (ii) as expeditiously as possible prepare and file with the Commission any amendments and supplements to the Registration Statement and the prospectus included in the Registration Statement as may be necessary to keep the Registration Statement effective for a period of not less than 120 days from the effective date; (iii) as expeditiously as possible furnish to each selling Stockholder such reasonable numbers of copies of the prospectus, including a preliminary prospectus in conformity with the requirements of the Securities Act, and such other documents as the selling Stockholder may reasonably request in order to facilitate the public sale or other disposition of the Registrable Shares owned by the selling Stockholder; and (iv) as expeditiously as possible use its best efforts to register or qualify the Registrable Shares covered by the Registration Statement under the Securities or Blue Sky laws of such states as the selling Stockholders shall reasonably request, and do any and all other acts and things that may be necessary or desirable to enable the selling Stockholders to consummate the public sale or other disposition in such states of the Registrable Shares owned by the selling Stockholder; PROVIDED, HOWEVER, that the Company shall not be required in connection with this paragraph (iv) to qualify as a foreign corporation or execute a general consent to service of process in any jurisdiction. If the Company has delivered preliminary or final prospectuses to the selling Stockholders and after having done so the prospectus is amended to comply with the requirements of the Securities Act, the Company shall promptly notify the selling Stockholders and, if requested, the selling Stockholders shall immediately cease making offers of Registrable Shares and return all prospectuses to the Company. The Company shall promptly provide the selling Stockholders with revised prospectuses and, following receipt of the revised prospectuses, 22 <PAGE> 23 the selling Stockholders shall be free to resume making offers of the Registrable Shares. (f) ALLOCATION OF EXPENSES. The Company will pay all Registration Expenses of all registrations under this Agreement; provided, however, that if a registration is withdrawn at the request of the Stockholders requesting such registration (other than as a result of material adverse information concerning the Business or financial condition of the Company which is made known to the Stockholders after the date on which such registration was requested) and if the requesting Stockholders elect not to have such registration counted as a registration requested under subsection 8(c), the requesting Stockholders shall pay the Registration Expenses of such registration pro rata in accordance with the number of their Registrable Shares included in such registration. For purposes of this Section, the term "Registration Expenses" shall mean all expenses incurred by the Company in complying with this Section 8, including, without limitation, all registration and filing fees, exchange listing fees, printing expenses, fees and disbursements of counsel for the Company and the fees and expenses of one counsel selected by the selling Stockholders to represent the selling Stockholders, state Blue Sky fees and expenses, and the expense of any special audits incident to or required by any such registration, but excluding underwriting discounts, selling commissions and the fees and expenses of selling Stockholders' own counsel (other than the counsel selected to represent all selling Stockholders). (g) INDEMNIFICATION. In the event of any registration of any of the Registrable Shares under the Securities Act pursuant to this Agreement, the Company will indemnify and hold harmless the seller of such Registrable Shares, each underwriter of such Registrable Shares, and each other person, if any, who controls such seller or underwriter within the meaning of the Securities Act or the Exchange Act against any losses, claims, damages or liabilities, joint or several, to which such seller, underwriter or controlling person may become subject under the Securities Act, the Exchange Act, state securities or Blue Sky laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement under which such Registrable Shares were registered under the Securities Act, any preliminary prospectus or final prospectus contained in the Registration Statement, or any amendment or supplement to such Registration Statement, or arise out of or are based upon the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading; and the Company will reimburse such seller, underwriter and each such controlling person for any legal or any other expenses reasonably incurred by such seller, underwriter or controlling person in connection with investigating or defending any such loss, claim, damage, liability or action; PROVIDED, HOWEVER, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any untrue statement or omission made in such Registration Statement, preliminary prospectus or prospectus, or any such amendment or supplement, in reliance upon and in conformity with information furnished to the Company, in writing, by or on behalf of such seller, underwriter or controlling person specifically for use in the preparation thereof. 23 <PAGE> 24 In the event of any registration of any of the Registrable Shares under the Securities Act pursuant to this Agreement, each seller of Registrable Shares, severally and not jointly, will indemnify and hold harmless the Company, each of its directors and officers and each underwriter (if any) and each person, if any, who controls the Company or any such underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages or liabilities, joint or several, to which the Company, such directors and officers, underwriter or controlling person may become subject under the Securities Act, Exchange Act, state securities or Blue Sky laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement under which such Registrable Shares were registered under the Securities Act, any preliminary prospectus or final prospectus contained in the Registration Statement, or any amendment or supplement to the Registration Statement, or arise out of or are based upon any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, if the statement or omission was made in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of such seller, specifically for use in connection with the preparation of such Registration Statement, prospectus, amendment or supplement; PROVIDED, HOWEVER, that the obligations of such Stockholders hereunder shall be limited to an amount equal to the proceeds to each Stockholder of Registrable Shares sold as contemplated herein. Each party entitled to indemnification under this subsection 8(g) (the "INDEMNIFIED PARTY") shall give notice to the party required to provide indemnification (the "INDEMNIFYING PARTY") promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; PROVIDED, that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld); and, PROVIDED, FURTHER, that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 8. The Indemnified Party may participate in such defense at such party's expense; PROVIDED, HOWEVER, that the Indemnifying Party shall pay such expense if representation of such Indemnified Party by the counsel retained by the Indemnifying Party would be inappropriate due to actual or potential differing interests between the Indemnified Party and any other party represented by such counsel in such proceeding. No Indemnifying Party, in the defense of any such claim or litigation shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect of such claim or litigation, and no Indemnified Party shall consent to entry of any judgment or settle such claim or 24 <PAGE> 25 litigation without the prior written consent of the Indemnifying Party. (h) INDEMNIFICATION WITH RESPECT TO UNDERWRITTEN OFFERING. In the event that Registrable Shares are sold pursuant to a Registration Statement in an underwritten offering pursuant to subsection 8(c)(i), the Company agrees to enter into an underwriting agreement containing customary representations and warranties with respect to the Business and operations of an issuer of the Securities being registered and customary covenants and agreements to be performed by such issuer, including without limitation customary provisions with respect to indemnification by the Company of the underwriters of such offering. (i) INFORMATION BY HOLDER. Each holder of Registrable Shares included in any registration shall furnish to the Company such information regarding such holder and the distribution proposed by such holder as the Company may request in writing and as shall be required in connection with any registration, qualification or compliance referred to in this Section 8. (j) "STAND-OFF" AGREEMENT. Each Stockholder, if requested by the Company and an underwriter of Common Stock or other Securities of the Company, shall agree not to sell or otherwise transfer or dispose of any Registrable Shares or other Securities of the Company held by such Stockholder for a specified period of time (not to exceed 120 days) following the effective date of a Registration Statement; PROVIDED, that: (i) such agreement shall only apply to the first such Registration Statement covering Common Stock of the Company to be sold on its behalf to the public in an underwritten offering; and (ii) all Stockholders holding not less than the number of shares of Common Stock held by such Stockholder (including shares of Common Stock issuable upon the conversion of Shares, or other convertible Securities, or upon the exercise of options, warrants or rights), all Founders and all officers and directors of the Company enter into similar agreements. Such agreement shall be in writing in a form satisfactory to the Company and such underwriter. The Company may impose stop-transfer instructions with respect to the Registrable Shares or other Securities subject to the foregoing restriction until the end of the stand-off period. (k) LIMITATIONS ON SUBSEQUENT REGISTRATION RIGHTS. The Company shall not, without the prior written consent of Stockholders holding at least a majority of the Registrable Shares, enter into any agreement (other than this Agreement) with any holder or prospective holder of any Securities of the Company which would allow such holder or prospective holder (i) to include Securities of the Company in any registration filed under subsection 8(c) or 8(d), or (ii) to make a demand registration which could result in such registration statement being declared effective prior to December 31, 2002. 25 <PAGE> 26 (l) RULE 144 REQUIREMENTS.
