Since the date of the Base Balance Sheet there has not been any: (i) material adverse change in the financial condition of the Company or in the assets, liabilities, properties, business or prospects of the Company, (ii) declaration, setting aside or payment of any dividend or other distribution with respect to, or any direct or indirect redemption or acquisition of, any of the capital stock of the Company, (iii) waiver of any valuable right of the Company or cancellation of any debt or claim held by the Company, (iv) loss, destruction or damage to any property which is material to the assets, liabilities, properties, business or prospects of the Company, whether or not insured, (v) acquisition or disposition of any assets (or any contract or arrangement therefor) or other transaction by the Company, other than in the ordinary course of business, (vi) loan by the Company to any officer, director, employee or Founder of the Company, or any agreement or commitment therefor, (vii) increase, direct or indirect, in the compensation paid or payable to any officer, director, employee or agent of the Company, (viii) material loss of personnel of the Company, material change in the terms and conditions of the employment of the Company's key personnel or any labor trouble involving the Company, (ix) arrangements relating to any royalty, dividend or similar payment based on the sales volume of the Company, whether as part of the terms of the Company's capital stock or by any separate agreement, other than pursuant to any Fixed Point Microwave Services Agreement System by and between the Company and an "Incumbent" or any Agreement to Create and Manage a Telecommunications System by and between the Company and an "Incumbent" or the Consulting Agreement among the Company and Stephen A.

All of the accounts receivable of the Company, whether shown or reflected on the Base Balance Sheet or otherwise, represent bona fide completed sales made in the ordinary course of business, are valid and enforceable claims, are subject to no known set-offs or counterclaims, and are, in the best judgment of the Company, fully collectible in the normal course of business after deducting the reserve set forth in the Base Balance Sheet and adjusted since that date, which reserve is a reasonable estimate of the Company's uncollectible accounts. 2.9 TITLE TO PROPERTIES. SCHEDULE 2.9 hereto sets forth the addresses and uses of all real property that the Company owns, leases or subleases. The Company has good, valid and (if applicable) marketable title to all of its assets including, without limitation, all rights to those assets reflected on the Base Balance Sheet or acquired by it after the date thereof (except for properties disposed of since that date in the ordinary course of business), free and clear of all liens, claims or encumbrances of any nature, except as set forth in SCHEDULE 2.9 hereto. All equipment included in such properties which is necessary to the business of the Company is in good condition and repair (ordinary wear and tear excepted) and all leases of real or personal property to which the Company is a party are fully effective and afford the Company peaceful and undisturbed possession of the subject matter of the lease. The property and assets of the Company are sufficient for the conduct of its business as presently conducted. The Company is not in violation of any zoning, building or safety ordinance, regulation or requirement or other law or regulation applicable to the operation of its owned or leased properties, which violation would have a material adverse effect on the assets, liabilities, properties, business or prospects of the Company, nor has it received any notice of any such violation. There are no defaults by the Company or to the best knowledge of the Company, by any other party, which might curtail in any material respect the present use of the Company's property listed on SCHEDULE 2.9 hereof. The performance by the Company of this Agreement will not result in the termination of, or in any increase of any amounts payable under any lease listed on SCHEDULE 2.9 hereof. 10 2.10 TAX MATTERS. The Company has filed all federal, state, local and foreign income, excise and franchise tax returns, real estate and personal property tax returns, sales and use tax returns and other tax returns required to be filed by it where the failure to file such returns would have a material adverse effect on the assets, liabilities, properties, business or prospects of the Company and has paid all taxes owing by it, except taxes which have not yet accrued or otherwise become due, for which adequate provision has been made in the pertinent financial statements referred to in SECTION 2.5 above or which will not have a material adverse effect on the business or financial condition of the Company. The provision for taxes on the Base Balance Sheet is sufficient as of its date for the payment of all accrued and unpaid federal, state, county and local taxes of any nature of the Company, and any applicable taxes owing to any foreign jurisdiction, whether or not assessed or disputed. All taxes and other assessments and levies which the Company is required to withhold or collect have been withheld and collected and have been paid over to the proper governmental authorities, except where the failure to withhold or collect and pay over would not have a material adverse effect on the assets, liabilities, properties, business or prospects of the Company. With regard to the federal income tax returns of the Company, the Company has never received notice of any audit or of any proposed deficiencies from the Internal Revenue Service. There are in effect no waivers of applicable statutes of limitation with respect to any taxes owed by the Company for any year. Neither the Internal Revenue Service nor any other taxing authority is now asserting or, to the best knowledge of the Company, threatening to assert against the Company any deficiency or claim for additional taxes or interest thereon or penalties in connection therewith. 2.11 CERTAIN CONTRACTS AND ARRANGEMENTS.

(a The Founder agrees that he will not directly or indirectly offer, transfer donate, sell, assign, pledge, hypothecate or otherwise dispose of (any such action a "Transfer"), all or any portion of the shares of capital stock of the Company now owned or hereafter acquired by him, except in connection with, and strictly in compliance with the conditions of, any of the following (hereinafter "Permitted Transfers"): (i) Transfers effected pursuant to SECTION 5.2, SECTION 5.3 and SECTION 5.4 hereof, in each case made in accordance with the procedures set forth therein; (ii) Transfers by the Founder to his spouse or children or to a trust of which he is the settlor or a trustee for the benefit of his spouse or children, PROVIDED that such trust does not require or permit distribution of such shares during the term of this Agreement, and PROVIDED FURTHER that the transferee shall have entered into an enforceable written agreement satisfactory to the Company and the Investors, providing that all shares so Transferred shall continue to be subject to all provisions of this Agreement as if such shares were still held by the Founder; and (iii) Transfers upon the Founder's death to his heirs, executors or administrators or to a trust under his will or Transfers between the Founder and his guardian or conservator, PROVIDED that the transferee shall have entered into an enforceable written agreement satisfactory to the Company and the Investors, providing that all shares so Transferred shall continue to be subject to all provisions of this Agreement as if such shares were still held by the Founder. (b Anything to the contrary in this Agreement notwithstanding, transferees of the Founder permitted by clauses (ii) and (iii) of SECTION 5.1(A) shall take any shares so Transferred subject to all provisions of this Agreement as if such shares were still held by the Founder, whether or not they so agree with the Founder. 31 5.2 RIGHT OF REFUSAL. If at any time on or after the Closing Date, the Founder (including for all purposes of this SECTION 5.2, any permitted transferee of his shares pursuant to SECTION 5.1(A)(II) or SECTION 5.1(A)(III) receives a bona fide offer to purchase any or all of his shares (the "Offer") from an unaffiliated third party (the "Offeror") which the Founder wishes to accept (whether initiated by the Founder or the third party), the Founder may transfer such shares pursuant to and in accordance with the following provisions of this SECTION 5.2: (a The Founder shall cause the Offer to be reduced to writing and shall notify the Investors in writing of his desire to accept the Offer and otherwise comply with the provisions of this SECTION 5.2, SECTION 5.3 and SECTION 5.4. The Founder's notice shall constitute an irrevocable offer to sell such shares to the Investors at a purchase price equal to the price contained in, and on the same terms and conditions of, the Offer. The notice shall be accompanied by a true copy of the Offer (which shall identify the Offeror). (b At any time within 45 days after the date of the giving of notice pursuant to SECTION 5.2(A) (the "Notice Period"), one or more of the Investors may, subject to the terms hereof, choose to accept the Offer with respect to all or a portion of the shares covered thereby by giving written notice to the Founder to such effect; provided that if two or more Investors choose, in the aggregate, to accept such Offer with respect to an aggregate number of shares which exceeds the number of shares subject to such Offer and available for purchase by the Investors, the number of shares for which the Offer may be accepted by each such Investor shall, in each case, be reduced by the smallest number of shares as shall be necessary to reduce the aggregate number of shares for which the Offer may be accepted by the Investors as contemplated herein to the number of shares for which the Offer was made and which are available for purchase by them; PROVIDED, FURTHER, that the number of shares for which any Investor may accept such Offer as contemplated herein shall in no event be reduced to less than the number of shares which bears the same proportion to the total number of shares for which the Offer was made and which are available for purchase by the Investors as the number of Securities then held by such Investor bears to the total number of Securities then held by all Investors accepting such Offer; and PROVIDED FURTHER, that the Investors who elect to purchase shares may purchase any shares which other Investors do not elect to purchase based on the relative holdings of such electing Investors. (c If shares covered by any Offer are purchased pursuant to SECTION 5.2(B), such purchase shall be (i) at the same price and on the same terms and conditions as the Offer if the Offer is for cash and/or notes or (ii) if the Offer includes any consideration other than cash and notes, then at the equivalent all cash price for such other consideration. The closing of the purchase of the shares subject to an Offer pursuant to this SECTION 5.2 shall take place within 15 days after the expiration of the Notice Period, or upon satisfaction of any governmental approval requirements, if later, by delivery by the respective Investors of the purchase price for the shares 32 being purchased as provided above to the Founder against delivery of the certificates representing the shares so purchased, appropriately endorsed for transfer by the Founder. 5.3 RIGHT OF CO-SALE. 33 In the event the Founder proposes to sell any shares, including following the receipt of an Offer wherein any of the shares subject thereto are not purchased pursuant to SECTION 5.2, the Founder may transfer the shares subject thereto only following compliance with this SECTION 5.3 and SECTION 5.4 below. In such event, immediately following the last day of the Notice Period, the Founder shall give an additional notice of the proposed sale to the Investors, once again enclosing a copy of the Offer, if applicable, which shall identify the Offeror and the number of shares proposed to be sold (the "Co-Sale Notice"). Each of the Investors thereupon shall have the right, and exercisable upon written notice to the Founder within 20 days after delivery to it of the Co-Sale Notice (the "Co-Sale Notice Period"), to participate in the sale on the terms and conditions stated in the Offer and in the Co-Sale Notice, except that Investors may elect to sell Securities, as applicable, as then held by them on an as converted basis. Each of the Investors shall have the right to sell all or any portion of its Securities on the terms and conditions in the Co-Sale Notice, with the maximum number of Securities equal to the product obtained by multiplying the number of shares to be sold by the Founder as described in the Co-Sale Notice by a fraction, the numerator of which is the number of Securities owned by such Investor on the date of the Co-Sale Notice, as the case may be, and the denominator of which is the sum of the number of shares of the Common Stock owned by the Founder and the number of Securities owned by all of the Investors, as of the date of the Co-Sale Notice, calculated on a fully diluted basis. To the extent one or more Investors elect not to sell the full amount of its Securities of any class which they are entitled to sell pursuant to this SECTION 5.3, the other participating Investors' rights to sell shares shall be increased proportionately to their relative holdings of Securities, such that the Investors shall have the right to sell the full number of Securities allocable to them in any transaction subject to this SECTION 5.3 even if some Investors elect not to participate. Within five days after the expiration of the Co-Sale Notice Period, the Founder shall notify each participating Investor of the number of shares held by the Investor that will be included in the sale and the date on which the sale will be consummated, which shall be no later than the later of (i) 30 days after the delivery of the Co-Sale Notice by the Founder and (ii) the satisfaction of all governmental approval requirements, if any. Each of the Investors may effect its participation in any Offer hereunder by delivery to the Offeror, or to the Founder for transfer to the Offeror, of one or more instruments, certificates and/or option agreements, properly endorsed for transfer, representing the shares it elects to sell therein. At the time of consummation of the Offer, the Offeror shall remit directly to each Investor that portion of the sale proceeds to which each Investor is entitled by reason of its participation therein. All costs and expenses in connection with any sales pursuant to this SECTION 5.3 shall be paid for by the sellers of shares on a pro rata basis (based on participation rather than holdings) or otherwise as they may have agreed; PROVIDED, HOWEVER, that all costs and expenses in connection with any sale pursuant to this SECTION 5.3 that relate specifically or incrementally to participation therein by an Investor (including the fees and expenses of counsel to such selling Investor, if any) shall be paid for by such Investor. No shares may be purchased by the Offeror from the Founder unless the Offeror simultaneously purchases from the Investors all of the shares that they have elected to sell pursuant to this SECTION 5.3. 34 5.4 SALES BY THE FOUNDER. Any shares covered by an Offer which are not acquired pursuant to SECTION 5.2 that the Founder desires to sell following compliance with SECTION 5.2 and SECTION 5.3 may be sold to the Offeror only during the 90-day period after the expiration of the Co-Sale Notice Period and only on terms no more favorable to the Founder than those contained in the Offer. Promptly after such sale, the Founder shall notify the Investors of the consummation thereof and shall furnish such evidence of the completion and time of completion of such sale and of the terms thereof as may reasonably be requested by the Investors. So long as the Offeror is neither a party, nor an affiliate or relative of a party to this Agreement, such Offeror shall take the shares so Transferred free and clear of the provisions of this Agreement, other than SECTION 4.4 hereof. If, at the end of such 90-day period, the Founder has not completed the sale of such shares as aforesaid, all the restrictions on Transfer contained in this Agreement shall again be in effect with respect to such shares. 5.5 ASSIGNMENT/MISCELLANEOUS. Each Investor shall have the right to assign its rights under this SECTION 5 to any transferee of all or any portion of its Securities, or to any fund managed by or associated with such Investor, who thereupon shall be deemed an Investor hereunder. Any transferee of shares of the Founder (other than a transferee in accordance with SECTION 5.4 except as provided therein) shall be bound by and subject to the restrictions and agreements set forth in this SECTION 5 for the benefit of the Investors and all certificates representing shares held by the Founder shall bear a legend to such effect. Any transfers of shares of Common Stock or Securities by or to the Investors or the Founder under this SECTION 5 shall comply with all applicable requirements of the Federal Communications Commission (the "FCC") and federal telecommunications law, including any relevant limitations on foreign ownership of FCC licenses. SECTION 6. RIGHTS TO PURCHASE Notwithstanding anything herein to the contrary, the following provisions of this SECTION 6 shall terminate immediately prior to the closing of a Qualified Public Offering. 35 6.1 RIGHT TO PARTICIPATE IN CERTAIN SALES OF ADDITIONAL SECURITIES. The Company agrees that it will not sell or issue any shares of capital stock of the Company, or other securities convertible into or exchangeable for capital stock of the Company, or options, warrants or rights carrying any rights to purchase capital stock of the Company unless the Company first submits a written offer to the Founder and the Investors identifying the terms of the proposed sale (including cash price, number or aggregate principal amount of securities and all other material terms), and offers to the Founder and each Investor the opportunity to purchase its Pro Rata Share (as hereinafter defined) of the securities (subject to increase for over-allotment if the Founder or some Investors do not fully exercise their rights) on terms and conditions, including price, not less favorable to the Founder and the Investors than those on which the Company proposes to sell such securities to a third party. The Founder's and each Investor's "Pro Rata Share" of such securities shall be based on the ratio which all of the shares of capital stock of the Company owned by such party bears to all the issued and outstanding shares of capital stock of the Company owned by the Founder and the Investors, and Common Stock equivalents of the Company, calculated, in each case, on a fully-diluted basis. The Company's offer to the Founder and the Investors shall remain open and irrevocable for a period of 30 days, and those parties who elect to purchase ("Electing Purchasers") shall have the first right to take up and purchase any shares which other parties do not elect to purchase, based on the relative holdings of the Electing Purchasers. Any securities so offered which are not purchased pursuant to such offer may be sold by the Company but only on the terms and conditions set forth in the initial offer to the Founder and Investors, at any time within 120 days following the termination of the above-referenced 30-day period but may not be sold to any other person or on terms and conditions, including price, that are more favorable to the purchaser than those set forth in such offer or after such 120-day period without renewed compliance with this SECTION 6.1. Notwithstanding the foregoing, the Company may (i) issue options to purchase 148,418 shares of Common Stock to the Founder, which options shall have terms and conditions which are approved by a majority of the Investor Directors, (ii) issue, or issue options, warrants or rights to subscribe for, up to an aggregate of 801,892 shares of its Common Stock (as appropriately adjusted for stock splits, stock dividend and the like) to officers, employees and directors of the Company other than the Founder pursuant to the terms of the 1995 Plan and the 1997 Plan and SECTION 4.5 hereof and may issue shares of its Common Stock upon the exercise of any such stock options, or upon exercise of warrants outstanding as of the Closing, (iii) issue Series C Preferred Stock at the Additional Closing, (iv) issue Series A Conversion Shares, Series B Conversion Shares and Series C Conversion Shares upon the conversion of the Preferred Shares, (as appropriately adjusted for stock splits, stock dividend and the like); and (v) issue shares of its Common Stock in connection with the acquisition of another Company. 36 The Series A Investors and Series B Investors acknowledge that, with respect to the issuance of the Series C Preferred Stock, they have either exercised (and are purchasing shares of Series C Preferred Stock hereunder) or waived any preemptive rights granted to them under the Series A Agreement and Series B Agreement. 6.2 ASSIGNMENT OF RIGHTS. Each Investor may assign its rights under this SECTION 6 to either any transferee of its shares or any fund affiliated or associated with such Investor, thereupon shall be deemed an Investor hereunder. SECTION 7. REGISTRATION RIGHTS 7.1 OPTIONAL REGISTRATIONS. 37 If at any time or times after the date hereof, the Company shall seek to register any shares of its capital stock or securities convertible into capital stock under the Securities Act (whether in connection with a public offering of securities by the Company (a "primary offering"), a public offering of securities by Founders of the Company (a "secondary offering"), or both), the Company will promptly give written notice thereof to each Investor holding Registrable Securities (as hereinafter defined in SECTION 7.4 below) then outstanding (the "Holders"). If within 30 days after their receipt of such notice one or more Investors request the inclusion of some or all of the Registrable Securities owned by them in such registration, the Company will use its best efforts to effect the registration under the Securities Act of all Registrable Securities which such Investors may request in a writing delivered to the Company within 30 days after the notice given by the Company. In the case of the registration of shares of capital stock by the Company in connection with any underwritten public offering, if the underwriter(s) determines that marketing factors require a limitation on the number of Registrable Securities to be offered, the Company shall not be required to register Registrable Securities of the Investors in excess of the amount, if any, of shares of the capital stock which the principal underwriter of such underwritten offering shall reasonably and in good faith agree to include in such offering in excess of any amount to be registered for the Company. If any limitation of the number of shares of capital stock to be registered by the Investors is required pursuant to this SECTION 7.1, the number of shares that may be included in the registration on behalf of the Investors shall be allocated among the Investors or the holders of any other registration rights in proportion, as nearly as practicable, to their respective holdings of Registrable Securities, after first excluding from such registration statement all shares of Common Stock sought to be included therein by (i) any director, officer or employee of the Company, (ii) any holder thereof not having any such contractual incidental registration rights, and (iii) any holder, thereof having contractual, incidental registration rights subordinate and junior to the rights of the Investors. In any event, if such underwritten public offering is not an initial public offering, then the Investors holding Registrable Securities shall be allowed to include not less than thirty-five percent (35%) of the shares subject to such registration statement. The Company will not grant any rights relating to the piggy-back registration of its capital stock which are superior to or on a parity with the rights granted to the Investors in this SECTION 7.1. The provisions of this SECTION 7.1 will not apply to a registration effected solely to implement (i) an employee benefit plan, or (ii) a transaction to which Rule 145 or any other similar rule of the Securities and Exchange Commission (the "SEC") under the Securities Act is applicable. 38 7.2 REQUIRED REGISTRATIONS. If on any three (3) occasions after the date hereof the Investors holding a majority of the Registrable Securities held by all Investors notify the Company in writing that the Investors intend to offer or cause to be offered for public sale all or any portion of its or their Registrable Securities, the Company will notify all of the Investors who would be entitled to notice of a proposed registration under SECTION 7.1 above of its receipt of such notification from such Investor or Investors and any other holder of piggyback registration rights. Upon the written request of any such Investor delivered to the Company within 20 days after receipt from the Company of such notification, the Company will either (i) elect to make a primary offering in which case the rights of such Investors to participate in such offering shall be as set forth in SECTION 7.1 above (except that the Company shall not be permitted to limit the number of shares which may be registered by any Investor and such Investor will have the right to select the underwriter), or (ii) use its best efforts to cause such of the Registrable Securities as may be requested by any Investors to be registered under the Securities Act in accordance with the terms of this SECTION 7.2. The Company may postpone the filing of any registration statement required hereunder for a reasonable period of time, not to exceed 60 days during any twelve-month period, if the Company has been advised by legal counsel that such filing would require a special audit or the disclosure of a material impending transaction or other matter and the Company determines reasonably and in good faith that such disclosure would have a material adverse effect on the Company. The Company shall not be required to cause a registration statement requested pursuant to this SECTION 7.2 to become effective prior to 90 days following the effective date of a registration statement initiated by the Company, if the request for registration has been received by the Company subsequent to the giving of written notice by the Company, made in good faith, to the Investors holding Registrable Securities that the Company is commencing to prepare a Company-initiated registration statement (other than a registration effected solely to implement an employee benefit plan or a transaction to which Rule 145 or any other similar rule of the SEC under the Securities Act is applicable); PROVIDED, HOWEVER, that the Company shall use its best efforts to achieve such effectiveness promptly. 7.3 FORM S-3. 39 If the Company becomes eligible to use Form S-3 under the Securities Act or a comparable successor form, the Company shall use its best efforts to continue to qualify at all times for registration on Form S-3 or such successor form. One or more of the Investors holding Registrable Securities shall have the right to request and have effected one registration per year of shares of Registrable Securities on Form S-3 or such successor form for a public offering of shares of Registrable Securities having an aggregate proposed offering price exceeding $500,000 (such requests shall be in writing and shall state the number of shares of Registrable Securities to be disposed of and the intended method of disposition of such shares by such Investor or Investors). The Company shall not be required to cause a registration statement requested pursuant to this SECTION 7.3 to become effective prior to 90 days following the effective date of a registration statement initiated by the Company, if the request for registration has been received by the Company subsequent to the giving of written notice by the Company, made in good faith, to the Investors holding Registrable Securities to the effect that the Company is commencing to prepare a Company-initiated registration statement (other than a registration effected solely to implement an employee benefit plan or a transaction to which Rule 145 or any other similar rule of the Commission under the Securities Act is applicable); PROVIDED, HOWEVER, that the Company shall use its best efforts to achieve such effectiveness promptly following such 90-day period if the request pursuant to this SECTION 7.3 has been made prior to the expiration of such 90-day period. The Company may postpone the filing of any Registration Statement required hereunder for a reasonable period of time, not to exceed 60 days during any twelve-month period, if the Company has been advised by legal counsel that such filing would require the disclosure of a material transaction or other factor and the Company determines reasonably and in good faith that such disclosure would have a material adverse effect on the Company. The Company shall give notice to all Investors holding Registrable Securities of the receipt of a request for registration pursuant to this SECTION 7.3 and shall provide a reasonable opportunity for such Investors to participate in the registration. Subject to the foregoing, the Company will use in best efforts to effect promptly the registration of all shares of Common Stock on Form S-3 or such successor form to the extent requested by the Investor or Investors thereof for purposes of disposition. If so requested by any Investor in connection with a registration under this SECTION 7.3, the Company shall take such steps as are required to register such Investor's Registrable Securities for sale on a delayed or continuous basis under Rule 415, and to keep such registration effective for the shorter of (a) six months or (b) until all of such Investor's Registrable Securities registered thereunder are sold. 40 7.4 REGISTRABLE SECURITIES. For the purposes this SECTION 7, the term "Registrable Securities" shall mean any shares of the Common Stock purchased by, or issued to, an Investor, or issuable upon conversion of the Preferred Shares, including without limitation any Series A Conversion Shares, Series B Conversion Shares or Series C Conversion Shares issued or issuable upon conversion of any and all of the Preferred Shares and including any Common Stock issued by way of a stock dividend or stock split or in connection with a combination of shares, recapitalization, merger, consolidation or other reorganization; provided, however, that if an Investor owns Preferred Shares, the Investor shall not be required to cause such Preferred Shares to be converted to Common Stock until immediately prior to the effective date of any applicable registration statement pursuant to which such shares will be sold. 7.5 FURTHER OBLIGATIONS OF THE COMPANY. Whenever the Company is required hereunder to register any Registrable Securities, it agrees that it shall also do the following: (a Pay all expenses of such registrations and offerings (exclusive of underwriting discounts and commissions) and the reasonable fees and expenses, not to exceed $60,000 per offering, of not more than one independent counsel for the Investors satisfactory to a majority in interest of the Securities, voting as a single class. (b Use its best efforts (with due regard to management of the ongoing business of the Company and the allocation of managerial resources) diligently to prepare and file with the SEC a registration statement and such amendments and supplements to said registration statement and the prospectus used in connection therewith as may be necessary to keep said registration statement effective at least 90 days and to comply with the provisions of the Securities Act with respect to the sale of securities covered by said registration for the period necessary to complete the proposed public offering; (c Furnish to each selling Investor such copies of each preliminary and final prospectus and such other documents as such Investor may reasonably request to facilitate the public offering of its Registrable Securities; (d Enter into any reasonable underwriting agreement required by the proposed underwriter for the selling Investors, if any, in such form and containing such terms as are customary; PROVIDED, HOWEVER, that no Investor shall be required to make any representations or warranties other than with respect to its title to the Registrable Securities and any written information provided by the Investors to the Company, and if the underwriter requires that representations or warranties be made, the Company shall make all such representations and warranties relating to the Company; 41 (e Use its best efforts to register or qualify the securities covered by said registration statement under the securities or blue-sky laws of such jurisdictions as any selling Investor may reasonably request, provided that the Company shall not be required to register or qualify the securities in any jurisdictions which require it to qualify to do business therein; (f Immediately notify each selling Investor, at any time when a prospectus relating to his Registrable Securities is required to be delivered under the Securities Act, of the happening of any event as a result of which such prospectus contains an untrue statement of a material fact or omits any material fact necessary to make the statements therein not misleading, and, at the request of any such selling Investor, prepare a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus will not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading; (g Cause all such Registrable Securities to be listed on each securities exchange or quotation system on which similar securities issued by the Company are then listed or quoted; (h Otherwise use its best efforts to comply with the securities laws of the United States and other applicable jurisdictions and all applicable rules and regulations of the SEC and comparable governmental agencies in other applicable jurisdictions and make generally available to its holders, in each case as soon as practicable, but not later than 45 days after the close of the period covered thereby, an earnings statement of the Company which will satisfy the provisions of Section 11(a) of the Securities Act; (i Obtain and furnish to each selling Investor, immediately prior to the effectiveness of the registration statement (and, in the case of an underwritten offering, at the time of delivery of any Registrable Securities sold pursuant thereto), a cold comfort letter from the Company's independent public accountants in customary form and covering such matters of the type customarily covered by cold comfort letters as the holders of a majority of the Registrable Securities being sold may reasonably request; and (j Otherwise cooperate with the underwriter or underwriters, the Commission and other regulatory agencies and take all actions and execute and deliver or cause to be executed and delivered all documents necessary to effect the registration of any Registrable Securities under this SECTION 7. 7.6 INDEMNIFICATION; CONTRIBUTION. 42 (a Incident to any registration statement referred to in this SECTION 7, and subject to applicable law, the Company will indemnify and hold harmless each underwriter, each Investor who offers or sells any such Registrable Securities in connection with such registration statement (including its partners (including partners of partners and stockholders of any such partners)), and directors, officers, employees and agents of any of them (a "Selling Investor"), and each person who controls any of them within the meaning of Section 15 of the Securities Act or Section 20 of the Securities Exchange Act of 1934, as amended (the "Exchange Act") (a "Controlling Person")), from and against any and all losses, claims, damages, expenses and liabilities, joint or several (including any investigation, legal and other expenses incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted), to which they, 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, insofar as such losses, claims, damages or liabilities arise out of or are based on (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement (including any related preliminary or definitive prospectus, or any amendment or supplement to such registration statement or prospectus), (ii) any omission or alleged omission to state in such document a material fact required to be stated in it or necessary to make the statements in it not misleading, or (iii) any violation by the Company of the Securities Act, any state securities or blue sky laws or any rule or regulation thereunder in connection with such registration; PROVIDED, HOWEVER, that the Company will not be liable to the extent that such loss, claim, damage, expense or liability arises from and is based on an untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information furnished in writing to the Company by such underwriter, Selling Investor or Controlling Person expressly for use in such registration statement. With respect to such untrue statement or omission or alleged untrue statement or omission in the information furnished in writing to the Company by such Selling Investor expressly for use in such registration statement, such Selling Investor will indemnify and hold harmless each underwriter, the Company (including its directors, officers, employees and agents), each other Investor (including its partners (including partners of partners and stockholders of such partners)) and directors, officers, employees and agents of any of them) so registered, and each person who controls any of them 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, expenses and liabilities, joint or several, to which they, 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 to the same extent provided in the immediately preceding sentence. In no event, however, shall the liability of a Selling Investor for indemnification under this SECTION 7.6(A) in its capacity as such (and not in its capacity as an officer or director of the Company) exceed the lesser of (i) that proportion of the total of such losses, claims, damages or liabilities indemnified against equal to the proportion of the total securities sold under such registration statement which is being sold by such Selling Investor or (ii) the proceeds received by such Selling Investor from its sale of Registrable Securities under such registration statement. 43 (b If the indemnification provided for in SECTION 7.6(a) above for any reason is held by a court of competent jurisdiction to be unavailable to an indemnified party in respect of any losses, claims, damages, expenses or liabilities referred to therein, then each indemnifying party under this SECTION 7.6, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, expenses or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, the other Selling Investors and the underwriters from the offering of the Registrable Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, the other Selling Investors and the underwriters in connection with the statements or omissions which resulted in such losses, claims, damages, expenses or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company, the Selling Investors and the underwriters shall be deemed to be in the same respective proportions that the net proceeds from the offering (before deducting expenses) received by the Company and the Selling Investors and the underwriting discount received by the underwriters, in each case as set forth in the table on the cover page of the applicable prospectus, bear to the aggregate public offering price of the Registrable Securities. The relative fault of the Company, the Selling Investors and the underwriters 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 Company, the Selling Investors or the underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Selling Investors and the underwriters agree that it would not be just and equitable if contribution pursuant to this SECTION 7.6(b) were determined by pro rata or per capita allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. In no event, however, shall a Selling Investor be required to contribute any amount under this SECTION 7.6(b) in excess of the lesser of (i) that proportion of the total of such losses, claims, damages or liabilities indemnified against equal to the proportion of the total Registrable Securities sold under such registration statement which are being sold by such Selling Investor or (ii) the proceeds received by such Selling Investor from its sale of Registrable Securities under such registration statement. No person found 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 found guilty of such fraudulent misrepresentation. (c The amount paid by an indemnifying party or payable to an indemnified party as a result of the losses, claims, damages and liabilities referred to in this SECTION 7.6 shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim, payable as the same are incurred. The indemnification and contribution provided for in this SECTION 7.6 will remain in full force and effect regardless of any investigation 44 made by or on behalf of the indemnified parties or any officer, director, employee, agent or controlling person of the indemnified parties. 7.7 RULE 144 AND RULE 144A REQUIREMENTS. In the event that the Company becomes subject to Section 13 or Section 15(d) of the Exchange Act, the Company shall use its best efforts to take all action as may be required as a condition to the availability of Rule 144 or Rule 144A under the Securities Act (or any successor or similar exemptive rules hereafter in effect). The Company shall furnish to any Investor holding Registrable Securities, within 15 days of a written request, a written statement executed by the Company as to the steps it has taken to comply with the current public information requirement of Rule 144 or Rule 144A or such successor rules. The Founder agrees not to sell or otherwise transfer or dispose of any securities of the Company following the effective date of any registration statement of the Company for such period of time as may be agreed to by a majority in interest of the Investors or as otherwise requested in good faith by the Company or the underwriter in connection with the applicable offering. 7.8 TRANSFER OF REGISTRATION RIGHTS. The registration rights and related obligations under this SECTION 7 of the Investors with respect to their Registrable Securities may be assigned to any transferee of Registrable Securities held by them, and upon such transfer the relevant transferee shall be deemed to be included within the definition of an Investor, for purposes of this SECTION 7. The relevant Investor as the case may be, shall notify the Company at the time of such transfer. 7.9 MARKET STAND-OFF AGREEMENT. The Investors and the Founder, if requested by the underwriter of the Company's securities, shall agree not to sell, pledge, encumber or otherwise transfer or dispose of any Common Stock (or other securities) of the Company held by such Investors and the Founder during the 180-day period following the effective date of the Company's initial public offering or any subsequent underwritten offering hereunder in which the Investors are participating. Such agreement shall be in writing in form reasonably satisfactory to the Company and such underwriter. The Company may impose stop-transfer instructions with respect to the shares (or securities) subject to the foregoing restriction until the end of such 180-day period. 45 SECTION 8. GENERAL 8.1 Amendments, Waivers and Consents. For the purposes of this Agreement and all agreements executed pursuant hereto, no course of dealing between the Company and any Investor and no delay on the part of any party hereto in exercising any rights hereunder or thereunder shall operate as a waiver of the rights hereof and thereof. No provision hereof may be waived otherwise than by a written instrument signed by the party so waiving such covenant or other provision; PROVIDED, HOWEVER, changes in or additions to, and any consents required by, this Agreement may be made, and compliance with any term, covenant, condition or provision set forth herein may be omitted or waived (either generally or in a particular instance and either retroactively or prospectively) by a consent of the holders of a majority of the Preferred Shares; PROVIDED that any amendment, waiver or consent that adversely affects the Series A Investors, the Series B Investors or the Series C Investors or affects any rights specifically granted to the Series A Investors, the Series B Investors or the Series C Investors shall not be approved without the approval of the holders of a majority of the issued and outstanding Series A Preferred Stock, Series B Preferred Stock or Series C Preferred Stock, respectively; PROVIDED FURTHER, that any amendment, waiver or consent that adversely affects one Investor, or affects any rights specifically granted to such Investor, in a manner different than all other Investors holding the same series of Preferred Shares, including, but not limited to, the right to designate certain directors set forth in SECTION 4.4 and the right to be appointed to the Compensation Committee set forth in SECTION 4.5, shall not be approved without such Investor's consent. Any amendment or waiver effected in accordance with this SECTION 8.1 shall be binding upon each holder of the Preferred Shares at the time outstanding, each future holder of Preferred Shares and Securities and the Company. 46 8.2 INDEMNIFICATION; EXPENSES. (a Without limitation of any other provision of this Agreement, the Company agrees to defend, indemnify and hold the Investors and their affiliates and their respective direct and indirect partners, members, stockholders, directors, officers, employees and agents and each person who controls any of them within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (parties receiving the benefit of the indemnification agreement herein shall be referred to collectively as "Indemnified Parties" and individually as an "Indemnified Party") harmless from and against any and all losses, claims, damages, obligations, liens, assessments, judgments, fines, liabilities, and other costs and expenses (including, without limitation, interest, penalties and any investigation, legal and other expenses incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted, as the same are incurred) of any kind or nature whatsoever which may be sustained or suffered by any such Indemnified Party, without regard to any investigation by any of the Indemnified Parties, based upon, arising out of, by reason of or otherwise in respect of or in connection with (a) any inaccuracy in or breach of any representation or warranty made by the Company in this Agreement or in any agreement or instrument or other document delivered pursuant to this Agreement, (b) any breach of any covenant or agreement made by the Company in this Agreement or in any agreement or instrument delivered pursuant to this Agreement and (c) any action taken or omitted to be taken or alleged to have been taken or omitted to have been taken by any Indemnified Party as Founder, director, agent, representative or controlling person of the Company including, without limitation, any and all losses, claims, damages, expenses and liabilities, joint or several (including any investigation, legal and other expenses incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted, as the same may be incurred) arising or alleged to arise under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise; provided, however, that the Company will not be liable to the extent that such loss, claim, damage, expense or liability arises from and is based on (i) an untrue statement or omission or alleged untrue statement or omission in a registration statement or prospectus which is made in reliance on and in conformity with written information furnished to the Company in an instrument duly executed by or on behalf of such Indemnified Party specifically stating that it is for use in the preparation thereof or (ii) a knowing and willful violation of the federal securities laws by an Indemnified Party, as finally determined by a court of competent jurisdiction. (b If the indemnification provided for in SECTION 8.2(A) above for any reason is held by a court of competent jurisdiction to be unavailable to a Indemnified Party in respect of any losses, claims, damages, expenses or liabilities referred to therein, then the Company, in lieu of indemnifying such Indemnified Party thereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages, expenses or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Investors, 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 47 referred to in clause (i) above but also the relative fault of the Company and the Investors in connection with the action or inaction which resulted in such losses, claims, damages, expenses or liabilities, as well as any other relevant equitable considerations. In connection with any registration of the Company's securities, the relative benefits received by the Company and the Investors shall be deemed to be in the same respective proportions that the net proceeds from the offering (before deducting expenses) received by the Company and the Investors, in each case as set forth in the table on the cover page of the applicable prospectus, bear to the aggregate public offering price of the securities so offered. The relative fault of the Company and the Investors 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 Company or the Investors and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Investors agree that it would not be just and equitable if contribution pursuant to this SECTION 8.2(b) were determined by pro rata or per capita allocation or by any other methods of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. In connection with the registration of the Company's securities, in no event shall a Investor be required to contribute any amount under this SECTION 8.2(b) in excess of the lesser of (i) that proportion of the total of such losses, claims, damages or liabilities indemnified against equal to the proportion of the total securities sold under such registration statement which is being sold by such Investor or (ii) the proceeds received by such Investor from its sale of securities under such registration statement. No person found 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 found guilty of such fraudulent misrepresentation. (c The indemnification and contribution provided for in this SECTION 8.2 will remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Parties or any officer, director, employee, agent or controlling person of the Indemnified Parties. (d The provisions of this SECTION 8.2, are in addition to and shall supplement those set forth in SECTION 7.5, which shall apply in the case of the registration and sale of Registrable Securities held by any of the Investors registered pursuant to SECTION 7 hereof. (e Subject to the consummation of the Initial Closing, the Company agrees to pay and hold the Investors harmless against liability for payment of all reasonable costs and expenses incurred prior to or in connection with their investment in the Company, including the fees and disbursements of counsel and other professionals, including all costs and expenses that they incur with respect to the registration, execution, delivery and performance of this Agreement in an aggregate amount up to $37,000. In addition, the Company agrees to pay any and all stamp, transfer and other similar taxes (together in each case with interest and penalties, if any) 48 payable or determined to be payable in connection with the execution and delivery of this Agreement and the issuance of securities hereunder. 8.3 RESCISSION RIGHTS. If at any time there shall have occurred any material breach by the Company or the Founder of any of the representations, warranties and statements made or contained in this Agreement or in the documents, certificates, Schedules and Exhibits hereto, or in the information concerning the business of the Company or the Founder given or delivered to the Investors prior to the Closing Date (without limitation of the Investors' rights in connection with any matter constituting such a breach that becomes manifest subsequent to the Closing Date or Additional Closing Date, as the case may be) in connection with and pursuant to this Agreement, the Company shall immediately repay to the Investors the full purchase price of the Securities owned by such Investor together with interest calculated at the rate of ten percent (10%) per annum from the Closing Date or Additional Closing Date, as the case may be, to the date payment is made under this SECTION 8.3 in respect of the Securities. Notwithstanding anything contained herein to the contrary, the remedy described above is not intended to be and shall not be the exclusive remedy of any Investor and is in addition to any other remedies which any Investor may have under this Agreement or otherwise, whether in law or in equity. 8.4 SURVIVAL OF REPRESENTATIONS; WARRANTIES AND COVENANTS; ASSIGNABILITY OF RIGHTS. All covenants, agreements, representations and warranties of the Company and, to the extent applicable, the Founders, made herein and to be performed prior to or at the Initial Closing or Additional Closing, as the case may be, and in the certificates, lists, exhibits, schedules or other written information delivered or furnished to any Investor in connection herewith (a) shall be deemed to have been relied upon by such Investor, and shall survive for a period of 36 months after the Closing Date and (b) shall bind the Company's and the Founders' successors and assigns, whether so expressed or not, and, except as otherwise provided in this Agreement, all such covenants, agreements, representations and warranties shall inure to the benefit of the Investors' successors and assigns and to transferees of the Securities, whether so expressed or not. For purposes of this Agreement, the Company's successors shall include any corporation in to which the Company is merged in connection with its reincorporation, and as a condition to the consummation of such a transaction, the Investors shall receive an opinion of counsel that the successor corporation will be bound by his Agreement and that the Investors may tack their holding period with respect to the Securities for purposes of Rule 144. 8.5 LEGEND ON SECURITIES. The Company, the Investors and the Founder acknowledge and agree that the following legend shall be typed on each certificate evidencing any of the Securities issued hereunder held at any time by the Investors or the Founder: 49 "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE ACT) OR ANY STATE SECURITIES OR BLUE SKY LAWS AND MAY NOT BE OFFERED, SOLD, TRANSFERRED, HYPOTHECATED OR OTHERWISE ASSIGNED EXCEPT (1) PURSUANT TO A REGISTRATION STATEMENT WITH RESPECT TO SUCH SECURITIES WHICH IS EFFECTIVE UNDER THE ACT OR (2) PURSUANT TO AN AVAILABLE EXEMPTION FROM REGISTRATION UNDER THE ACT RELATING TO THE DISPOSITION OF SECURITIES AND (3) IN ACCORDANCE WITH APPLICABLE STATE SECURITIES AND BLUE SKY LAWS.
