Item 5. Other Events. ------------- On October 29, 2001, CMGI, Inc. (the "Company") entered into an agreement with Compaq Computer Corporation ("Compaq") and Compaq Financial Services Corporation ("CFS"). Compaq agreed to deem its $220.0 million in face amount of notes payable, plus the accrued interest thereon, issued by the Company paid in full in exchange for $75.0 million in cash, approximately $7.0 million in shares of the Company's common stock, and the Company's 49% ownership interest in its affiliate B2E Solutions, LLC. The number of shares of the Company's common stock to be issued to Compaq will be determined based on the average closing price of the Company's common stock during the eleven trading day period beginning five trading days prior to October 29, 2001. Additionally as part of this agreement, NaviSite, Inc. ("NaviSite"), a subsidiary of the Company, agreed to purchase certain equipment, which NaviSite currently leases from CFS, by issuing a note payable in the face amount of approximately $35.0 million. CFS and the Company also agreed to loan NaviSite $20.0 million and $10.0 million, respectively, in cash. In exchange for the cash infusion, NaviSite will issue notes payable in the face amounts of $20.0 million and $10.0 million to CFS and the Company, respectively, making the total notes payable issued by NaviSite to CFS and the Company, approximately $55 million and $10 million, respectively. The notes will require payment of interest only, at 12% per annum, for the first three years from the date of issuance and then repayment of interest and principal, on a straight-line basis, over the next three years until maturity on the sixth anniversary of the date of issuance. At NaviSite's option, it may make interest payments (i) 100% in shares of NaviSite common stock, in the case of the Company and (ii) approximately 16.67% in shares of NaviSite common stock through December 2003, in the case of CFS. Subject to NaviSite stockholder approval, the principal balance may be convertible into NaviSite common stock at the option of the holders at any time prior to or at maturity at a rate of $0.26 per share. If this conversion feature is exercised by CFS, the Company's ownership in NaviSite would drop below 50% and the Company would no longer consolidate NaviSite's financial results which currently represent a substantial portion of its Infrastructure and Enabling Technologies segment. The Company also agreed to convert its $80.0 million in principal amounts of notes receivable from NaviSite into approximately 14.5 million shares of NaviSite common stock. The Company also agreed to convert approximately $16.2 million in other amounts receivable from NaviSite into approximately 9.9 million shares of NaviSite common stock. Also as part of the agreement with Compaq and CFS, AltaVista Company ("AltaVista"), a subsidiary of the Company, agreed to purchase certain equipment, which AltaVista currently leases from CFS, for $20.0 million in cash. The foregoing description of the agreements by and among the Company, NaviSite, AltaVista and Compaq and its affiliates does not purport to be complete and is qualified in its entirety by reference to the full text of such agreements which are filed as exhibits to this Current Report on Form 8-K and are incorporated herein by reference.

Section 8.05. NaviSite Stockholder Meeting; etc. (a) Without limiting the generality of the foregoing, NaviSite shall cause a meeting of NaviSite's stockholders (the "NAVISITE STOCKHOLDER MEETING") to be duly called and held as soon as reasonably practicable (and shall use its best efforts to cause such meeting to be held no later than December 31, 2001), for the purpose of approving the authorization and issuance of shares of NaviSite Common Stock upon conversion of the senior secured convertible notes to be issued under the NaviSite Note Purchase Agreement (such matters, the "STOCKHOLDER MATTERS"), and CMGI irrevocably agrees to (and to cause its Affiliates to) vote all shares of NaviSite Common Stock now or hereinafter owned beneficially or of record by it or any of its Affiliates (the "OWNED NAVISITE SHARES") in favor of the Stockholder Matters at the NaviSite Stockholder Meeting (or any adjournment thereof), and that it will not vote any such shares in favor of any corporate action that would frustrate the purpose, or prevent or delay the consummation, of the transactions contemplated hereby. CMGI hereby represents and warrants to Compaq that the voting power represented by the Owned NaviSite Shares is sufficient to cause the approval of the Stockholder Matters at the NaviSite Stockholder Meeting. In connection with such meeting, CMGI (but only to the extent relating to the Stockholder Matters) and NaviSite will (i) promptly prepare and file with the SEC, use their best efforts 12

to have cleared by the SEC and thereafter mail to NaviSite's stockholders as promptly as practicable, such proxy or information statement (and any amendments or supplements thereto) (the "NAVISITE PROXY STATEMENT") as, in form and substance, when filed, will comply in all material respects with the applicable requirements of the Exchange Act, (ii) use their best efforts to obtain the necessary approvals by NaviSite's stockholders of the Stockholder Matters, and (iii) otherwise comply in all material respects with all legal requirements applicable to such meeting and the Stockholder Matters. Compaq, NaviSite and CMGI shall cooperate with each other in connection with the preparation of the NaviSite Proxy Statement and Compaq shall use commercially reasonable efforts to provide to NaviSite and CMGI any information relating to Compaq that is reasonably requested by NaviSite or CMGI and necessary for the preparation thereof. (b) Each of CMGI (but only to the extent relating to the Stockholder Matters) and NaviSite represents and warrants to Compaq and CFS that, at the time a NaviSite Proxy Statement is first mailed to NaviSite's stockholders, and at the time of the vote by NaviSite's stockholders on the Stockholder Matters, the NaviSite Proxy Statement, as supplemented or amended, if applicable, will not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading. (c) CMGI hereby revokes (and agrees to cause its Affiliates to revoke) any and all previous proxies granted with respect to the Owned NaviSite Shares. By entering into this Agreement, CMGI hereby grants (and agrees to cause its Affiliates to grant) a proxy appointing Compaq as CMGI's attorney-in-fact and proxy, with full power of substitution, for and in the NaviSite's name, to vote, express, consent or dissent, or otherwise to utilize such voting power solely in the manner contemplated by paragraph (a) above as Compaq or its proxy or substitute shall, in Compaq's sole discretion, deem proper with respect to the Owned NaviSite Shares (it being understood and agreed that in the event Compaq utilizes such proxy, it shall vote the Owned NaviSite Shares in favor of the approval of the Stockholder Matters). The proxy granted by CMGI is irrevocable and is granted in consideration of Compaq entering into this Agreement. The proxy shall become automatically revoked upon termination of this Agreement in accordance with its terms. (d) Except pursuant to the terms of this Agreement, prior to the approval of the Stockholder Matters at the NaviSite Stockholder Meeting, CMGI shall not, and shall not permit its Affiliates to, without the prior written consent of Compaq, directly or indirectly, (i) grant any proxies or enter into any voting trust or other agreement or arrangement with respect to the voting of any Owned NaviSite Shares or (ii) sell, assign, transfer, encumber or otherwise dispose of, or enter into any contract, option or other arrangement or understanding with respect 13

to the direct or indirect sale, assignment, transfer, encumbrance or other disposition of, any Owned NaviSite Shares. (e) If NaviSite's stockholders, for whatever reason, shall not have approved the Stockholder Matters by June 30, 2002, CFS shall thereafter have the right (the "OPTION") to purchase from CMGI (and CMGI shall be obligated to sell to CFS) 42,470,991 shares of NaviSite Common Stock (subject to adjustment for any stock split, stock dividend, recapitalization or other similar event) for $1.00 per share (subject to adjustment for any stock split, stock dividend, recapitalization or other similar event), payable in cash. The Option may be exercised in whole or in part at any time and from time to time, and shall expire on December 31, 2007 (except to the extent exercised before such date). The Option is irrevocable and is granted in consideration of CFS entering into this Agreement. The closing of the exercise of the Option will occur as soon as practicable after the exercise thereof (and in any event not later than 30 days after such exercise or, if later, five days after the date all necessary third party and governmental consents and approvals are obtained). CFS and CMGI shall use their best efforts to obtain as promptly as possible all third party and governmental consents necessary to consummate the closing of the exercise of the option. CFS may assign its right to acquire the Owned NaviSite Shares pursuant to the Option to an Affiliate, so long as CFS remains liable for the performance of such Affiliates' obligations with respect thereto.

Section 10.06. Severability. In case any provision of or obligation under this Agreement or the Notes or any other Financing Document shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions or obligations, or of such provision or obligation in any other jurisdiction, shall not in any way be affected or impaired thereby. 32

Section 10.07. Amendments And Waivers. Any provision of this Agreement or the Notes may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by the Company and the Required Holders; provided that no such amendment or waiver shall, unless signed by all of the Purchasers (i) reduce the principal of or rate of interest on any Note or (ii) postpone the date fixed for any payment of principal on any Note or of interest on any Note. Section 10.08. Successors And Assigns; Registration. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns (including any transferee of any Note), except that the Company may not assign or otherwise transfer any of its rights under this Agreement without the prior written consent of the Required Holders. (b) Either of the Purchasers may at any time assign or transfer all, or a proportionate part of all of its rights and obligations under this Agreement and the Notes only with the prior written consent of the Company and each other Purchaser (each, a "NON-ASSIGNING PURCHASER"), which consent shall not be unreasonably withheld or delayed; provided that the consent of the Company and the Non-Assigning Purchasers shall not be required for such assignments or transfers (i) to an Affiliate of a Purchaser or (ii) to another Purchaser. Subject to the restriction contained in the foregoing sentence, the terms and provisions of this Agreement shall inure to the benefit of any transferee or assignee of any Note and, in the event of such transfer or assignment, the rights and privileges herein conferred upon the assigning Purchaser shall automatically extend to and be vested in such transferee or assignee, all such to the terms and conditions hereof.

(d) The Company shall maintain a register (the "NOTE REGISTER") of the Purchasers and all assignee Purchasers that are the holders of all the Notes issued pursuant to this Agreement. The Company will allow any Purchaser to inspect and copy such list at the Company's principal place of business during normal business hours. Prior to the due presentment for registration of transfer of any Note, the Company may deem and treat the Person in whose name a Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and premium and interest on such Note and for all other purposes whatsoever, and the Company shall not be affected by notice to the contrary. 33

THE HOLDER HEREOF, BY PURCHASING THIS SECURITY, AGREES FOR THE BENEFIT OF THE COMPANY THAT THIS SECURITY MAY BE RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (1) TO THE COMPANY, OR (2) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT. THE HOLDER OF THIS NOTE IS ENTITLED TO THE BENEFITS OF THE GUARANTEE AND SECURITY AGREEMENT DATED OCTOBER __, 2001 AMONG THE COMPANY, CERTAIN SUBSIDIARY GUARANTORS THERETO AND COMPAQ FINANCIAL SERVICES CORPORATION, AS AMENDED, MODIFIED AND SUPPLEMENTED FROM TIME TO TIME. ADDITIONALLY, THE HOLDER OF THIS NOTE IS ENTITLED TO THE BENEFITS OF THE AMENDMENT TO AND RESTATEMENT OF TO THE INVESTOR RIGHTS AGREEMENT DATED OCTOBER __, 2001 AMONG THE COMPANY, COMPAQ FINANCIAL SERVICES CORPORATION AND CMGI, INC., AS AMENDED, MODIFIED AND SUPPLEMENTED FROM TIME TO TIME. NAVISITE, INC. 12% Convertible, Senior, Secured Note Due December 31, 2007 U.S. $_______ October __, 2001 FOR VALUE RECEIVED, the undersigned, NaviSite, Inc., a Delaware corporation (the "COMPANY"), hereby promises to pay to __, a Delaware corporation (the "PURCHASER"), the principal sum of US$____ in twelve equal quarterly installments (each a "PRINCIPAL PAYMENT"), together with accrued but unpaid interest thereon, commencing on the first Interest Payment Date (as defined below) in 2005 and continuing on each Interest Payment Date thereafter (each date on which a Principal Payment is made, a "PRINCIPAL PAYMENT DATE")

until December 31, 2007 (the "MATURITY DATE"). The Company may not prepay this Note. Interest on the outstanding principal shall be at a rate of 12% per annum ("INTEREST"), calculated on the basis of a 360 day year consisting of twelve 30 day months, and will be payable quarterly in arrears on March 31, June 30, September 30 and December 31 of each year (each an "INTEREST PAYMENT DATE") beginning December 31, 2001 until the Maturity Date. Interest for first Interest Payment Date shall be calculated from the date of issuance hereof to the first Interest Payment Date. If all or a portion of a Principal Payment or Interest shall not be paid when due (whether at its stated maturity, by acceleration or otherwise), the Company hereby promises to pay, on demand, interest on such overdue amount from and including the due date to, but excluding, the date such amount is paid in full at 14% per annum (and until the date such overdue amount is paid in full, "Interest" on such overdue amount shall mean interest at such rate). This Note is being delivered pursuant to a Note Purchase Agreement, dated as of October 29, 2001, among the Company, the Purchaser and [CFS/CMGI] (the "NOTE PURCHASE AGREEMENT"). This Note is one of the Notes referred to in the Note Purchase Agreement, which among other things, contains provisions for the acceleration of the maturity hereof upon the happening of certain events and for the amendment or waiver of certain provisions of the Note Purchase Agreement, all upon the terms and conditions therein specified. 1. Certain Definitions. As used herein, the following terms have the following meanings: "CLOSING PRICE" shall mean, on any day, (i) the closing price of the Common Stock (or any other security for which a closing price must be determined) on a national securities exchange or as quoted on the Nasdaq National Market on such day, as reported by the Wall Street Journal or (ii) if the Common Stock (or any such other security) is quoted on the Nasdaq National Market but no sale occurs on such day, the average of the closing bid and asked prices of the Common Stock (or any such other security) on the Nasdaq National Market on such day, as reported by the Wall Street Journal or (iii) if the Common Stock (or any such other security) is not so listed or quoted, the average of the closing bid and asked prices of the Common Stock (or any such other security) in the U.S. over- the-counter market or (iv) if no such trading market is readily available, the fair market value of the Common Stock (or any such other security) as determined in accordance with Section 5(b) hereof. "CURRENT MARKET PRICE" of the Common Stock means the average of the daily Closing Prices of the Common Stock for the five consecutive trading days selected by the board of directors commencing not more than 20 trading days before, and ending not later than the date immediately preceding the record date fixed in connection with such event or, if there is no record date, the date of such event; provided, that the Current Market Price of the Common Stock in connection with a Spin-Off shall mean the average of the daily Closing Prices of 2

the Common Stock for the same five consecutive trading days used to determine the Fair Market Value of the securities being distributed in such Spin-Off. "FAIR MARKET VALUE" of the securities to be distributed to the holders of the Common Stock in connection with a Spin-Off shall mean the average of the daily Closing Prices of such securities for a five consecutive trading day period selected by the board of directors during the period beginning on the first day of trading of such securities after the effectiveness of such Spin-Off and ending not later than 20 days after the effectiveness of the Spin-Off. All capitalized terms used but not otherwise defined herein shall have the meaning ascribed to such terms in the Note Purchase Agreement. 2. Security. The Purchaser's right to payment pursuant to the terms of this Note shall be secured to the extent and on the terms and conditions set forth in the Security Agreement, and the terms and provisions of the Security Agreement are incorporated herein by reference. 3. Payment. Principal Payments on each Principal Payment Date and Interest on each Interest Payment Date shall be made by bank cashier's check payable to the Purchaser at the Purchaser's principal address set forth in Section 10.04 of the Note Purchase Agreement (or at such other place as the Purchaser hereof shall notify the Company in writing) or, if the Purchaser so specifies, by written notice to the Company given not less than two Business Days prior to the Principal Payment Date or the Interest Payment Date, as the case may be, by bank wire transfer, in immediately available funds, to the account so specified, in lawful money of the United States of America; provided that, at the election of the Company, so long as the Company is listed on the Nasdaq National Market, up to [one-sixth - CFS Note]/[100% - CMGI Note] of the amount of Interest due on any Interest Payment Date through and including the Interest Payment Date in December [2003 -CFS Note]/[2007-CMGI Note] may be paid in shares of Common Stock. The number of shares of Common Stock to be issued in payment of the Interest due on such Interest Payment Date shall equal the amount of such Interest to be paid in Common Stock divided by the average of the Closing Prices per share of the Common Stock on the five consecutive trading days ending on the trading day immediately preceding such Interest Payment Date. If any Principal Payment Date or any Interest Payment Date occurs on a date that is not a Business Day, then the Principal Sum or Interest then due shall be paid on the next succeeding Business Day. 4. Conversion. 3

(a) Conversion Rights. Subject to and in accordance with the provisions of this Section 4, at any time on or prior to the Maturity Date, the Purchaser may elect, in its sole discretion, to effect the conversion (the "CONVERSION") of all or any portion of the outstanding principal and interest due on this Note into shares of Common Stock. The number of shares of Common Stock into which the outstanding principal and accrued but unpaid interest (or portion thereof) shall be converted pursuant to this Section 4(a) shall be determined by dividing the amount of outstanding principal and interest the Purchaser has elected to convert by $0.26. The Conversion Price is subject to adjustment as provided in Section 5 hereof. (b) Manner of Effecting the Conversion. If the Purchaser elects to effect the Conversion pursuant to Section 4(a) hereof, the Purchaser shall deliver a duly executed written notice to the Company of such election (the "CONVERSION NOTICE"), and in such event the Conversion shall be deemed to have been effected at the close of business on the date such Conversion Notice is given. Upon any Conversion of this Note in accordance with the terms hereof, the rights of the Purchaser with respect to the outstanding principal and all interest pursuant to this Note shall cease and the Purchaser shall be deemed to have become the holder of record of the shares of Common Stock into which this Note shall have been converted, provided that, if the Purchaser elects to convert only a portion of the outstanding principal and interest pursuant to Section 4(a) hereof, then the Company will deliver a new note to the Purchaser, on the same terms and conditions as this Note, with respect to the portion of the outstanding principal and interest that is not converted (the "NEW NOTE"). Concurrently with the delivery of a Conversion Notice, the Purchaser shall surrender this Note to the Company. Promptly upon its receipt of a Conversion Notice, the Company shall (i) deliver to or upon the written order of the Purchaser, a certificate or certificates for the number of shares of Common Stock issuable upon such Conversion, (ii) make a cash payment in respect of any fraction of a share as provided in Section 4(c) hereof and (iii) if applicable, deliver a New Note as set forth in this Section 4(b). (c) Fractional Shares. No fractional shares shall be issued upon any Conversion. Instead of any fractional share which would otherwise be issuable upon a Conversion, the Company shall pay a cash amount in respect of such fractional share in an amount based upon the Closing Price of the Common Stock on the trading day immediately preceding such Conversion. (d) Notwithstanding anything contained herein, this Note may not be converted until the Company has obtained the stockholder approvals required in accordance with Rule 4350(i) of the National Association of Securities Dealers Manual and Delaware corporate law. 4

5. Antidilution Provisions. (a) The Conversion Price shall be subject to adjustment from time to time as follows: (i) STOCK SPLITS AND COMBINATIONS. In case the Company shall at any time or from time to time after the Closing Date (A) subdivide or split the outstanding shares of Common Stock, (B) combine or reclassify the outstanding shares of Common Stock into a smaller number of shares or (C) issue by reclassification of the shares of Common Stock any shares of Capital Stock of the Company, then, and in each such case, the Conversion Price in effect immediately prior to such event or the record date therefor, whichever is earlier, shall be adjusted so that the holder of this Note thereafter surrendered for conversion shall be entitled to receive the number of shares of Common Stock or other securities of the Company which such holder would have owned or have been entitled to receive after the occurrence of any of the events described above, had such Note been surrendered for conversion immediately prior to the occurrence of such event or the record date therefor, whichever is earlier. An adjustment made pursuant to this subparagraph (i) shall become effective at the close of business on the day upon which such corporate action becomes effective. Such adjustment shall be made successively whenever any event listed above shall occur. (ii) STOCK DIVIDENDS IN COMMON STOCK. In case the Company shall at any time or from time to time after the Closing pay a dividend or make a distribution in shares of Common Stock on any class of Capital Stock of the Company other than dividends or distributions of shares of Common Stock or other securities with respect to which adjustments are provided in Section 5(a)(i) above, the Conversion Price shall be adjusted so that the holder of this Note shall be entitled to receive upon conversion thereof, the number of shares of Common Stock determined by multiplying (A) the applicable Conversion Price by (B) a fraction, the numerator of which shall be the number of shares of Common Stock theretofore outstanding and the denominator of which shall be the sum of such number of shares and the total number of shares issued in such dividend or distribution. (iii) ISSUANCE OF RIGHTS OR WARRANTS. In case the Company shall issue to all holders of Common Stock rights or warrants entitling such holders to subscribe for or purchase Common Stock at a price per share less than the Current Market 5

Price, the Conversion Price in effect immediately prior to the close of business on the record date fixed for determination of stockholders entitled to receive such rights or warrants shall be reduced by multiplying such Conversion Price by a fraction, the numerator of which is the sum of the number of shares of Common Stock outstanding at the close of business on such record date and the number of shares of Common Stock that the aggregate offering price of the total number of shares of Common Stock so offered for subscription or purchase would purchase at such Current Market Price and the denominator of which is the sum of the number of shares of Common Stock outstanding at the close of business on such record date and the number of additional shares of Common Stock so offered for subscription or purchase. For purposes of this subparagraph (iii), the issuance of rights or warrants to subscribe for or purchase securities convertible into Common Stock shall be deemed to be the issuance of rights or warrants to purchase the Common Stock into which such securities are convertible at an aggregate offering price equal to the sum of the aggregate offering price of such securities and the minimum aggregate amount (if any) payable upon conversion of such securities into Common Stock. Such adjustment shall be made successively whenever any such event shall occur. (iv) DISTRIBUTION OF INDEBTEDNESS, SECURITIES OR ASSETS. In case the Company shall distribute to all holders of Common Stock (whether by dividend or in a merger, amalgamation or consolidation or otherwise) evidences of indebtedness, shares of Capital Stock of any class or series, other securities, cash or assets (other than Common Stock, rights or warrants referred to in subparagraph (iii) above and other than as a result of a Fundamental Change (as defined below)), the Conversion Price in effect immediately prior to the close of business on the record date fixed for determination of stockholders entitled to receive such distribution shall be reduced by multiplying such Conversion Price by a fraction, the numerator of which is the Current Market Price on such record date less the fair market value (as determined in good faith by the board of directors, except in the case of a Spin-Off (as defined below)) of the portion of such evidences of indebtedness, shares of capital stock, other securities, cash and assets so distributed applicable to one share of Common Stock, and the denominator of which is the Current Market Price. Such adjustment shall be made successively whenever any such event shall occur. In respect of a dividend or other distribution of shares of Capital Stock of any class or series, or similar equity interests, 6

of or relating to a subsidiary or other business unit of the Company (a "SPIN-OFF"), the adjustment to the Conversion Price under this subparagraph (iv) shall occur 20 trading days after the effective date of the Spin-Off. (v) ISSUANCE OF COMMON STOCK. In case the Company shall issue or sell any shares of Common Stock at a price per share less than the Current Market Price (other than any (i) such transaction as to which an adjustment is otherwise provided for in this Section 5, (ii) the issuance by the Company of Common Stock to pay interest pursuant to Section 3 hereof or in satisfaction of Affiliate Obligations or (iii) the issuance by the Company to directors, employees, consultants or advisors of the Company of shares of Common Stock, or grant of options or other rights to purchase or acquire Common Stock, at a price, or exercise price, as the case may be, no lower than the fair market value of the Common Stock (as reasonably determined by the independent directors of the Company in good faith as of the time of issuance or grant, as the case may be), so long as the aggregate number of shares of Common Stock that are so issued or with respect to which an option or other right is so granted under this clause (iii) does not exceed 14,500,000 shares or (iv) the issuance by the Company of Common Stock pursuant to the NaviSite warrants in accordance with their terms as of the date hereof the Conversion Price in effect immediately prior to the close of business on the date immediately preceding such issuance or sale shall be reduced by multiplying such Conversion Price by a fraction, the numerator of which is the sum of the number of shares of Common Stock outstanding at the close of business on the date immediately preceding such issuance or sale (giving assumed effect to the conversion of all convertible securities outstanding on the date hereof) to and the number of shares of Common Stock that the aggregate price paid for the total number of shares of Common Stock so issued or sold on such date would purchase at such Current Market Price and the denominator of which is the sum of the number of shares of Common Stock outstanding at the close of business on the date immediately preceding such issuance or sale (giving assumed effect to the conversion of all convertible securities outstanding on the date hereof) and the number of additional shares of Common Stock so issued or sold. For purposes of this subparagraph (v), the issuance of rights, options or warrants to purchase Common Stock or securities convertible or exchangeable for Common Stock shall be deemed to be the issuance of the Common Stock into which such securities are exercisable at an aggregate price equal to the sum of the aggregate price paid for such securities and the minimum aggregate amount (if any) payable upon exercise or conversion of such options, rights, warrants or securities for Common Stock, 7

and the date of issuance and sale for purposes hereof shall be the date upon which such options, rights or warrants were issued or amended. Such adjustment shall be made successively whenever any such event shall occur; provided that no adjustment shall be made upon exercise of any option, right or warrant. If an adjustment is made as the result of the issuance of an option, right, warrant or convertible security and such option, right, warrant or security expires unexercised or unconverted, the Conversion Price shall be readjusted to the price that would have been in effect if no such adjustment had been made. (vi) FUNDAMENTAL CHANGES. In case any transaction or event (including, without limitation, any merger, consolidation, combination, recapitalization, sale of assets, tender or exchange offer, reclassification, compulsory share exchange or liquidation) shall occur in which all or substantially all outstanding shares of Common Stock are converted into or exchanged or acquired for or constitute the right to receive stock, other securities, cash, property or assets (each, a "FUNDAMENTAL CHANGE"), the holder of this Note outstanding immediately prior to the occurrence of such Fundamental Change shall have the right upon any subsequent conversion to receive (but only out of legally available funds, to the extent required by applicable law) the kind and amount of stock, other securities, cash, property or assets that such holder would have received if such share had been converted immediately prior thereto. (b) (i) Subject to paragraph (b)(ii) below, each determination of the Closing Price pursuant to clause (iv) of the definition of "Closing Price" shall be made in good faith by the Company. Upon each determination of the fair market value of the Common Stock by the Company hereunder, the Company shall promptly give notice thereof to each Purchaser, setting forth in reasonable detail the calculation of such fair market value and the method and basis of determination thereof (the "Company Determination"). (ii) If the Required Holders shall disagree with the Company Determination and shall by notice to the Company given within 10 days after the Company's notice of the Company Determination (an "Appraisal Notice") elect to dispute the Company Determination, such dispute shall be resolved as set forth in paragraph (b)(iii) below; provided that such procedure shall not apply to any determination of fair market value made pursuant to Section 5(a)(v)(ii). 8

(iii) The Company shall within 10 days after an Appraisal Notice shall have been given pursuant to paragraph (b)(i) above engage an investment bank or other qualified appraisal firm reasonably acceptable to the Required Holders (the "APPRAISER") to make an independent determination of the fair market value of the Common Stock (the "APPRAISER DETERMINATION"). The Appraiser Determination shall be final and binding on the Company and the Purchasers. If the Company Determination and the Appraiser Determination differ by an amount of 15% or less of the Company Determination, then the costs of conducting the appraisal shall be borne equally by the Company and the Purchasers; if the Company Determination is greater than the Appraiser Determination by more than 15% of the Company Determination, then the costs of conducting the appraisal shall be borne entirely by the Purchasers; and if the Appraiser Determination is greater than the Company Determination by more than 15% of the Company Determination, then the costs of conducting the appraisal shall be borne entirely by the Company; provided that in each case costs separately incurred by the Company and any Purchasers shall be separately borne by them. (c) Anything in paragraph (a) to the contrary notwithstanding, the Company shall not be required to give effect to any adjustment in the Conversion Price unless and until the net effect of one or more adjustments (each of which shall be carried forward until counted toward adjustment), determined as above provided, shall have resulted in a change of the Conversion Price by at least 1%, and when the cumulative net effect of more than one adjustment so determined shall be to change the Conversion Price by at least 1%, such change in the Conversion Price shall thereupon be given effect. In the event that, at any time as a result of the provisions of this paragraph (b), the holder of this Note upon subsequent conversion shall become entitled to receive any shares of Capital Stock of the Company other than Common Stock, the number of such other shares so receivable upon conversion of this Note shall thereafter be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions contained herein. (d) In any case in which paragraph (a) requires that an adjustment as a result of any event is to become effective from and after a record date, the Company may elect to defer until after the occurrence of such event (i) issuing to the holder of this Note converted after such record date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion over and above the shares issuable on the basis of the Conversion Price in effect immediately prior to 9

adjustment and (ii) paying to such holder any amount in cash in lieu of a fractional share of Common Stock. (e) If the Company shall take a record of the holders of its Common Stock for the purpose of entitling them to receive a dividend or other distribution, and shall thereafter and before the distribution to stockholders thereof legally abandon its plan to pay or deliver such dividend or distribution, then thereafter no adjustment in the number of shares of Common Stock issuable upon exercise of the right of conversion or in the Conversion Price then in effect shall be required by reason of the taking of such record. (f) Upon any adjustment of the Conversion Price or the number of shares of Common Stock issuable upon the Conversion of this Note, a certificate, signed by (i) the Company's president and chief financial officer or (ii) any independent firm of certified public accountants of recognized national standing the Company selects at its own expense, setting forth in reasonable detail the events requiring the adjustment and the method by which such adjustment was calculated, shall be mailed to the Purchaser at the address set forth in Section 10.04 of the Note Purchase Agreement hereof and shall specify the adjusted Conversion Price and the number of shares of Common Stock issuable upon the Conversion of the Note after giving effect to the adjustment. (g) The Company shall not, by amendment of its Certificate of Incorporation or through any reorganization, recapitalization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but shall at all times in good faith assist in the carrying out of all provisions of this Section 5 and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Purchaser against impairment. (h) Except as otherwise provided herein, all sections of this Section 5 are intended to operate independently of one another. If an event occurs that requires the application of more than one section, all applicable sections shall be given independent effect. 6. Governing Laws. This Note shall be governed by, and construed in accordance with, the laws of the State of New York in all respects, including all matters of construction, validity and performance, without regard to the choice of law provisions thereof. 10

(b) With respect to each right to payment or performance included in the Collateral from time to time, the Transaction Lien granted therein includes a continuing security interest in (i) any Supporting Obligation that supports such payment or performance and (ii) any Lien that (x) secures such right to payment or performance or (y) secures any such Supporting Obligation. (c) The Transaction Liens are granted as security only and shall not subject the Collateral Representative or any other Secured Party to, or transfer or in any way affect or modify, any obligation or liability of any Lien Grantor with respect to any of the Collateral or any transaction in connection therewith. SECTION 4. General Representations and Warranties. Each Original Lien Grantor represents and warrants that: (a) Such Lien Grantor is a corporation1 duly organized, validly existing and in good standing under the laws of the jurisdiction identified as its jurisdiction of organization in its Perfection Certificate. ------------- 1 Modify as needed if any Original Lien Grantor is not a corporation. 9

(b) Schedule 1 lists all Equity Interests in Subsidiaries and Affiliates owned by such Lien Grantor as of the Effective Date. Such Lien Grantor holds all such Equity Interests directly (i.e., not through a Subsidiary, a Securities Intermediary or any other Person). (c) Except as set forth on the Perfection Certificate of such Lien Grantor, all Pledged Equity Interests owned by such Lien Grantor are owned by it free and clear of any Lien other than (i) the Transaction Liens and (ii) any tax liens, judgment liens and other Permitted Liens. All shares of capital stock included in such Pledged Equity Interests (including shares of capital stock in respect of which such Lien Grantor owns a Security Entitlement) have been duly authorized and validly issued and are fully paid and non-assessable. None of such Pledged Equity Interests is subject to any option to purchase or similar right of any Person. Such Lien Grantor is not and will not become a party to or otherwise bound by any agreement (except the Note Documents) which restricts in any manner the rights of any present or future holder of any Pledged Equity Interest with respect thereto. (d) Except as set forth on the Perfection Certificate of such Lien Grantor, such Lien Grantor has good and marketable title to all its Collateral (subject to exceptions that are, in the aggregate, not material), free and clear of any Lien other than Permitted Liens. (e) Such Lien Grantor has not performed any acts that might prevent the Collateral Representative from enforcing any of the provisions of the Security Documents or that would limit the Collateral Representative in any such enforcement. No financing statement, security agreement, mortgage or similar or equivalent document or instrument covering all or part of the Collateral owned by such Lien Grantor is on file or of record in any jurisdiction in which such filing or recording would be effective to perfect or record a Lien on such Collateral, except financing statements, mortgages or other similar or equivalent documents with respect to Permitted Liens. After the Effective Date, no Collateral owned by such Lien Grantor will be in the possession or under the Control of any other Person having a claim thereto or security interest therein, other than a Permitted Lien. (f) The Transaction Liens on all Collateral owned by such Lien Grantor (i) have been validly created, (ii) will attach to each item of such Collateral on the Effective Date (or, if such Lien Grantor first obtains rights thereto on a later date, on such later date) and (iii) when so attached, will secure all the Secured Obligations or such Lien Grantor's Secured Guarantee, as the case may be. (g) Such Lien Grantor has delivered a Perfection Certificate to the Collateral Representative. The information set forth therein is correct and 10

complete as of the Effective Date. Within 60 days after the Effective Date, such Lien Grantor will furnish to the Collateral Representative a file search report from each UCC filing office listed in its Perfection Certificate, showing the filing made at such filing office to perfect the Transaction Liens on its Collateral. (h) When UCC financing statements describing the Collateral as set forth in Schedule 1 to such Lien Grantor's Perfection Certificate have been filed in the offices specified in such Perfection Certificate, the Transaction Liens will constitute perfected security interests in the Collateral owned by such Lien Grantor to the extent that a security interest therein may be perfected by filing pursuant to the UCC, prior to all Liens and rights of others therein except Permitted Liens. (i) Such Lien Grantor has taken, and will continue to take, all actions necessary under the UCC to perfect its interest in (i) any Accounts or Chattel Paper purchased or otherwise acquired by it, as against its assignors and creditors of its assignors and (ii) any Payment Intangibles or promissory notes purchased or otherwise acquired by it, as against its assignors and creditors of its assignors. (j) Such Lien Grantor's Collateral is insured as required by the Note Purchase Agreement. (k) All of such Lien Grantor's Inventory has or will have been produced in compliance, in all material respects, with the applicable requirements of the Fair Labor Standards Act, as amended. SECTION 5. Further Assurances; General Covenants. Each Lien Grantor covenants as follows: (a) Such Lien Grantor will, from time to time, at the Company's expense, execute, deliver, file and record any statement, assignment, instrument, document, agreement or other paper and take any other action (including any intellectual property filing and any filing of financing or continuation statements under the UCC) that from time to time may be necessary or desirable, or that the Collateral Representative may request, in order to: (i) create, preserve, perfect, confirm or validate the Transaction Liens on such Lien Grantor's Collateral; (ii) enable the Collateral Representative and the other Secured Parties to obtain the full benefits of the Security Documents; or 11

(iii) enable the Collateral Representative to exercise and enforce any of its rights, powers and remedies with respect to any of such Lien Grantor's Collateral. To the extent permitted by applicable law, such Lien Grantor authorizes the Collateral Representative to execute and file such financing statements or continuation statements without such Lien Grantor's signature appearing thereon. Such Lien Grantor agrees that a carbon, photographic, photostatic or other reproduction of this Agreement or of a financing statement is sufficient as a financing statement. Such Lien Grantor constitutes the Collateral Representative its attorney-in-fact to execute and file all intellectual property filings and other filings required or so requested for the foregoing purposes, all acts of such attorney being hereby ratified and confirmed; and such power, being coupled with an interest, shall be irrevocable until all the Transaction Liens granted by such Lien Grantor terminate pursuant to Section 14. The Company will pay the costs of, or incidental to, any intellectual property filings and any recording or filing of any financing or continuation statements or other documents recorded or filed pursuant hereto in accordance with clause (ii) of the second sentence of Section 9.01 of the Note Purchase Agreement. (b) Such Lien Grantor will not (i) change its name or corporate structure, (ii) change its location (determined as provided in UCC Section 9-307) or (iii) become bound, as provided in UCC Section 9-203(d) or otherwise, by a security agreement entered into by another Person, unless it shall have given the Collateral Representative prior notice thereof. (c) At least 30 days before it takes any action contemplated by Section 5(b), such Lien Grantor will, at the Company's expense and at the request of the Purchasers, cause to be delivered to the Collateral Representative an Opinion of Counsel, in form and substance satisfactory to the Collateral Representative, to the effect that (i) all financing statements and amendments or supplements thereto, continuation statements and other documents required to be filed or recorded in order to perfect and protect the Transaction Liens against all creditors of and purchasers from such Lien Grantor after it takes such action (except any continuation statements specified in such Opinion of Counsel that are to be filed more than six months after the date thereof) have been filed or recorded in each office necessary for such purpose, (ii) all fees and taxes, if any, payable in connection with such filings or recordations have been paid in full and (iii) except as otherwise agreed by the Required Holders, such action will not adversely affect the perfection or priority of the Transaction Lien on any Collateral to be owned by such Lien Grantor after it takes such action or the accuracy of such Lien Grantor's representations and warranties herein relating to such Collateral. 12

(d) If any Collateral is located on premises leased by a Lien Grantor as lessee, such Lien Grantor shall, within 60 days of the date hereof in the case of leases in existence on the date hereof, and substantially simultaneously with the execution and delivery of such lease, in the case of leases hereafter entered into, use its reasonable efforts to secure from the landlord a waiver of contractual and statutory landlord's liens, an agreement to permit access to and removal of Collateral and other customary matters, all pursuant to an instrument in form and substance satisfactory to the Collateral Representative. (e) Such Lien Grantor will not sell, lease, exchange, assign or otherwise dispose of, or grant any option with respect to, any of its Collateral; provided that such Lien Grantor may do any of the foregoing unless (i) doing so would violate a covenant in the Note Purchase Agreement or (ii) an Event of Default shall have occurred and be continuing and the Collateral Representative shall have notified such Lien Grantor that its right to do so is terminated, suspended or otherwise limited. Concurrently with any sale, lease or other disposition (except a sale or disposition to another Lien Grantor or a lease) permitted by the foregoing proviso, the Transaction Liens on the assets sold or disposed of (but not in any Proceeds arising from such sale or disposition) will cease immediately without any action by the Collateral Representative or any other Secured Party. The Collateral Representative will, at the Company's expense, execute and deliver to the relevant Lien Grantor such documents as such Lien Grantor shall reasonably request to evidence the fact that any asset so sold or disposed of is no longer subject to a Transaction Lien. (f) Such Lien Grantor will, promptly upon request, provide to the Collateral Representative all information and evidence concerning such Lien Grantor's Collateral that the Collateral Representative may reasonably request from time to time to enable it to enforce the provisions of the Security Documents. SECTION 6. Investment Property. Each Lien Grantor represents, warrants and covenants as follows: (a) Certificated Securities. On the Effective Date (in the case of an Original Lien Grantor) or the date on which it signs and delivers its first Security Agreement Supplement (in the case of any other Lien Grantor), such Lien Grantor will deliver to the Collateral Representative as Collateral hereunder all certificates representing Pledged Certificated Securities then owned by such Lien Grantor. Thereafter, whenever such Lien Grantor acquires any other certificate representing a Pledged Certificated Security, such Lien Grantor will immediately deliver such certificate to the Collateral Representative as Collateral hereunder. 13

(b) Uncertificated Securities. On the Effective Date (in the case of an Original Lien Grantor) or the date on which it signs and delivers its first Security Agreement Supplement (in the case of any other Lien Grantor), such Lien Grantor will enter into (and cause the relevant issuer to enter into) an Issuer Control Agreement in respect of each Pledged Uncertificated Security then owned by such Lien Grantor and deliver such Issuer Control Agreement to the Collateral Representative (which shall enter into the same). Thereafter, whenever such Lien Grantor acquires any other Pledged Uncertificated Security, such Lien Grantor will enter into (and cause the relevant issuer to enter into) an Issuer Control Agreement in respect of such Pledged Uncertificated Security and deliver such Issuer Control Agreement to the Collateral Representative (which shall enter into the same). (c) Delivery of Pledged Certificates. All Pledged Certificates, when delivered to the Collateral Representative, will be in suitable form for transfer by delivery, or accompanied by duly executed instruments of transfer or assignment in blank, with signatures appropriately guaranteed, all in form and substance satisfactory to the Collateral Representative. SECTION 7. Collateral Accounts. (a) If and when required for purposes hereof, the Collateral Representative will establish with respect to each Lien Grantor an account (its "COLLATERAL ACCOUNT"), in the name and under the exclusive control of the Collateral Representative, into which all amounts owned by such Lien Grantor that are to be deposited therein pursuant to the Note Documents shall be deposited from time to time. Each Cash Collateral Account will be operated as provided in this Section. (b) The Collateral Representative shall deposit the following amounts, as and when received by it, in the Collateral Account of the applicable Lien Grantor: (i) each amount required by the Note Documents to be deposited therein, including, without limitation, all proceeds specified in Section 5.04(d) of the Note Purchase Agreement; and (ii) each amount realized or otherwise received by the Collateral Representative with respect to assets of such Lien Grantor upon any exercise of remedies pursuant to any Security Document. (c) Unless (x) an Event of Default shall have occurred and be continuing and the Required Holders shall have instructed the Collateral Representative to stop withdrawing amounts from the Collateral Account pursuant to this subsection or (y) the maturity of the Notes shall have been accelerated pursuant to Article 7 14

of the Note Purchase Agreement, the Collateral Representative shall withdraw amounts deposited in the Collateral Account in accordance with Section 5.04(d) of the Note Purchase Agreement and apply them to pay, or reimburse the Company and its Subsidiaries for paying, the cost of repairing, restoring or replacing the affected property to the extent that the Company has certified, no less than 5 Business Days prior to the date of such withdrawal, that (i) it and its Subsidiaries intend to apply all or any portion of such amounts to pay the cost of repairing, restoring or replacing the affected property and (ii) if such property is to be replaced, the property acquired to replace it will be included in the Collateral at least to the extent that the property to be replaced was included therein; (d) Funds held in any Collateral Account may, until withdrawn, be invested and reinvested in such Temporary Cash Investments as the relevant Lien Grantor shall request from time to time; provided that, if an Event of Default shall have occurred and be continuing, the Collateral Representative may select such Temporary Cash Investments. (e) If an Event of Default shall have occurred and be continuing, the Collateral Representative may withdraw any amounts held therein and apply such amounts as provided in Section 9. SECTION 8. Remedies upon Event of Default. (a) If an Event of Default shall have occurred and be continuing, the Collateral Representative may exercise (or cause its sub-agents to exercise) any or all of the remedies available to it (or to such sub-agents) under the Security Documents. (b) Without limiting the generality of the foregoing, if an Event of Default shall have occurred and be continuing, the Collateral Representative may exercise on behalf of the Secured Parties all the rights of a secured party under the UCC (whether or not in effect in the jurisdiction where such rights are exercised) with respect to any Collateral and, in addition, the Collateral Representative may, without being required to give any notice, except as herein provided or as may be required by mandatory provisions of law, withdraw all cash held in the Collateral Accounts and apply such cash as provided in Section 9 and, if there shall be no such cash or if such cash shall be insufficient to pay all the Secured Obligations in full, sell, lease, license or otherwise dispose of the Collateral or any part thereof. Notice of any such sale or other disposition shall be given to the relevant Lien Grantor(s) as required by Section 11. The foregoing provisions of this subsection shall apply to Real Property Collateral only to the extent permitted by applicable law and the provisions of any applicable Mortgage or other document. (c) Without limiting the generality of the foregoing, if an Event of Default shall have occurred and be continuing: 15

(i) the Collateral Representative may license or sublicense, whether general, special or otherwise, and whether on an exclusive or non-exclusive basis, any Pledged intellectual property (including any Pledged Recordable Intellectual Property) throughout the world for such term or terms, on such conditions and in such manner as the Collateral Representative shall in its sole discretion determine; provided that such licenses or sublicenses do not conflict with any existing license made available to the Collateral Representative; (ii) the Collateral Representative may (without assuming any obligation or liability thereunder), at any time and from time to time, in its sole and reasonable discretion, enforce (and shall have the exclusive right to enforce) against any licensee or sublicensee all rights and remedies of any Lien Grantor in, to and under any of its Pledged intellectual property and take or refrain from taking any action under any thereof, and each Lien Grantor releases the Collateral Representative and each other Secured Party from liability for, and agrees to hold the Collateral Representative and each other Secured Party free and harmless from and against any claims and expenses arising out of, any lawful action so taken or omitted to be taken with respect thereto, except for claims and expenses arising from the Collateral Representative's or such Secured Party's gross negligence or willful misconduct; and (iii) upon request by the Collateral Representative (which shall not be construed as implying any limitation on its rights or powers), each Lien Grantor will execute and deliver to the Collateral Representative a power of attorney, in form and substance satisfactory to the Collateral Representative, for the implementation of any sale, lease, license or other disposition of any of such Lien Grantor's Pledged intellectual property or any action related thereto. In connection with any such disposition, but subject to any confidentiality restrictions imposed on such Lien Grantor in any license or similar agreement, such Lien Grantor will supply to the Collateral Representative its know-how and expertise relating to the relevant intellectual property or the products or services made or rendered in connection with such intellectual property, and its customer lists and other records relating to such intellectual property and to the distribution of said products or services.

(f) The Collateral Representative may refuse to act on any notice, consent, direction or instruction from any Secured Parties or any agent, trustee or similar representative thereof that, in the Collateral Representative's opinion, (i) is contrary to law or the provisions of any Security Document or (ii) may expose the Collateral Representative to liability (unless the Collateral Representative shall have been indemnified, to its reasonable satisfaction, for such liability by the Secured Parties that gave such notice, consent, direction or instruction).

"STOCKHOLDERS" means the Purchasers and any persons or entities to whom the rights granted under this Agreement are transferred by the Purchasers, its successors or assigns, pursuant to Section 3.3 hereof. II. Registration Rights. 2.1 Required Registrations. (a) At any time, a Stockholder or Stockholders may request, in writing, that the Company effect the registration on Form S-1 or Form S-3 (or successor forms) of Registrable Shares owned by such Stockholder or Stockholders having an aggregate value of at least $2,500,000 (based on the then current public market price). (b) Upon receipt of any request for registration pursuant to this Section 2.1, the Company shall promptly give written notice of such proposed registration to all other Stockholders. Such Stockholders shall have the right, by giving written notice to the Company within 15 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 in the case of an underwritten offering to the approval of the managing underwriter as provided in Section 2.1(c) below. Thereupon, the Company shall, as expeditiously as possible, use its best efforts to effect the registration on an appropriate registration form of all Registrable Shares which the Company has been requested to so register. (c) If the Initiating Holders intend to distribute the Registrable Shares covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to Section 2.1(a) and the Company shall include such information in its written notice referred to in Section 2.1(b). The right of any other Stockholder to include its Registrable Shares in such registration pursuant to Section 2.1(a) shall be conditioned upon such other Stockholder's participation in such underwriting on the terms set forth herein. If the managing underwriter determines that the marketing factors require a limitation of the number of shares to be underwritten, the number of Registrable Shares to be included in a Registration Statement filed pursuant to this Section 2.1 shall be reduced pro rata among the requesting Stockholders based on the quotient of (i) the total Registrable Shares to be included in the Registration Statement, divided by (ii) the total number of Registrable Shares that requested registration. (d) The Initiating Holders shall have the right to select the managing underwriter(s) for any underwritten offering requested pursuant to Section 2.1(a), subject to the approval of the Company, which approval will not be unreasonably withheld. 3

(e) The Company shall not be required to effect more than five registrations initiated by CMGI pursuant to Section 2.1(a) or more than ten registrations initiated by CFS pursuant to Section 2.1(a). In addition, the Company shall not be required to effect any registration within 90 days after the effective date of any other Registration Statement of the Company relating to an underwritten offering. For purposes of this Section 2.1(e), a Registration Statement shall not be counted until such time as such Registration Statement has been declared effective by the Commission, unless the Initiating Holders withdraw their request for such registration (other than as a result of 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 elect not to pay the Registration Expenses therefor pursuant to Section 2.4. (f) If at the time of any request to register Registrable Shares by the Initiating Holders pursuant to this Section 2.1, the Company is engaged or has plans to engage in a registered public offering 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 or if financial statements required for the requested registration are not then available, then the Company may at its option direct that such request be delayed for a period not in excess of 90 days from the date of such request, such right to delay a request to be exercised by the Company not more than once in any 12-month period. 2.2 Incidental Registration. (a) Whenever the Company proposes to file a Registration Statement (other than a Registration Statement filed pursuant to Section 2.1) 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; provided, that no such notice need be given if no Registrable Shares are to be included therein as a result of a determination of the managing underwriter pursuant to Section 2.2(b). 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 Section 2.2 without obligation to any Stockholder. (b) If the registration for which the Company gives notice pursuant to Section 2.2(a) involves an underwriting, the Company shall so advise the Stockholders as a part of the written notice given pursuant to Section 2.2(a). In such event, the right of any Stockholder to include its Registrable Shares in such 4

registration pursuant to Section 2.2 shall be conditioned upon such Stockholder's participation in such underwriting on the terms set forth herein. All Stockholders proposing to distribute their securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for the underwriting by the Company. Notwithstanding any other provision of this Agreement, if the Company and the managing underwriter(s) determine in good faith that marketing factors require a limitation of the number of shares to be underwritten, then the Company and the managing underwriter(s) may exclude shares from the registration and the underwriting, and the number of shares that may be included in the registration and the underwriting shall be allocated, first to the Company or the Company stockholder(s) for which the registration was initiated, and second to each of the Stockholders requesting inclusion of their Registrable Shares in such registration and each of the other holders of piggyback registration rights on a parity with those Stockholders on a pro rata basis based on the total number of Registrable Shares and other securities requested for inclusion in such registration by each such Stockholder or other holder. If any holder of Registrable Shares or any other Company stockholder requesting inclusions of securities in the registration disapproves of the terms of any such underwriting, such person may elect to withdraw therefrom by written notice to the Company, and any Registrable Shares or other securities excluded or withdrawn from such underwriting shall be withdrawn from such registration. (c) Notwithstanding the foregoing, the Company shall not be required, pursuant to this Section 2.2, to include any Registrable Shares in a Registration Statement if such Registrable Shares can then be sold pursuant to Rule 144(k) under the Securities Act and represent less than 1% of the then outstanding shares of Common Stock. 2.3 Registration Procedures. (a) If and whenever the Company is required by the provisions of this Agreement to use its best efforts to effect the registration of any 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 effective as soon as possible; (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 comply with the provisions of the Securities Act (including the anti- fraud provisions thereof) and to keep the Registration Statement effective for 12 months from the effective date or such lesser period until all such Registrable Shares are sold; 5

(iii) as expeditiously as possible, furnish to each Selling Stockholder such reasonable numbers of copies of the Prospectus, including any preliminary Prospectus, in conformity with the requirements of the Securities Act, and such other documents as such Selling Stockholder may reasonably request in order to facilitate the public sale or other disposition of the Registrable Shares owned by such Selling Stockholder; (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; (v) as expeditiously as possible, cause all such Registrable Shares to be listed on each securities exchange or automated quotation system on which similar securities issued by the Company are then listed; and (vi) promptly make available for inspection by the Selling Stockholders, any managing underwriter participating in any disposition pursuant to such Registration Statement and any attorney or accountant or other agent retained by any such underwriter or selected by the Selling Stockholders, all financial and other records, pertinent corporate documents and properties of the Company and cause the Company's officers, directors, employees and independent accountants to supply all information reasonably requested by any such Selling Stockholder, underwriter, attorney, accountant or agent in connection with such Registration Statement. (b) If the Company has delivered a Prospectus 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, the Selling Stock holders shall be free to resume making offers of the Registrable Shares. (c) In the event that, in the judgment of the Company, it is advisable to suspend use of a Prospectus included in a Registration Statement due to pending material developments or other events that have not yet been publicly disclosed 6

and as to which the Company believes public disclosure would be detrimental to the Company, the Company shall notify all Selling Stockholders to such effect, and upon receipt of such notice, each such Selling Stockholder shall immediately discontinue any sales of Registrable Shares pursuant to such Registration Statement until such Selling Stockholder has received copies of a supplemented or amended Prospectus or until such Selling Stockholder is advised in writing by the Company that the then current Prospectus may be used and has received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in such Prospectus. Notwithstanding anything to the contrary herein, the Company shall not exercise its rights under this Section 2.3(c) to suspend sales of Registrable Shares for a period in excess of 90 days in any 365-day period. 2.4 Allocation of Expenses. The Company will pay all Registration Expenses for all registrations under this Agreement; provided, however, that if a registration under Section 2.1 is withdrawn at the request of the Initiating Holders (other than as a result of 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 Initiating Holders elect not to have such registration counted as a registration requested under Section 2.1, 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 Agreement, including, without limitation, all registration and filing fees, exchange listing fees, printing expenses, fees and expenses 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). 2.5 Indemnification and Contribution. (a) 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 Selling Stockholder, each underwriter of such Registrable Shares and each other person, if any, who controls such Selling Stockholder 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 Selling Stockholder, 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) (i) 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 7

prospectus or final prospectus contained in the Registration Statement or any amendment or supplement to such Registration Statement or (ii) 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 Selling Stockholder, underwriter and controlling person for any legal or any other expenses reasonably incurred by such Selling Stockholder, 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 Selling Stockholder, underwriter or controlling person specifically for use in the preparation thereof. (b) In the event of any registration of any of the Registrable Shares under the Securities Act pursuant to this Agreement, each Selling Stockholder, 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) (i) 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 (ii) 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 relating to such Selling Stockholder furnished in writing to the Company by or on behalf of such Selling Stockholder specifically for use in connection with the preparation of such Registration Statement, prospectus, amendment or supplement; provided, however, that the obligations of a Selling Stockholder hereunder shall be limited to an amount equal to the net proceeds to such Selling Stockholder of Registrable Shares sold in connection with such registration. (c) Each party entitled to indemnification under this Section 2.5 (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 8

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 2.5 except to the extent that the Indemnifying Party is adversely affected by such failure. The Indemnified Party may participate in such defense at such Indemnified 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; provided further that in no event shall the Indemnifying Party be required to pay the expenses of more than one law firm per jurisdiction as counsel for the Indemnified Party. The Indemnifying Party also shall be responsible for the expenses of such defense if the Indemnifying Party does not elect to assume such defense. 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 litigation without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld. (d) In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in this Section 2.5 is due in accordance with its terms but for any reason is held to be unavailable to an Indemnified Party in respect to any losses, claims, damages and liabilities referred to herein, then the Indemnifying Party shall, in lieu of indemnifying such Indemnified Party, contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages or liabilities to which such party may be subject in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and the Selling Stockholders on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of the Company and the Selling Stockholders shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of material fact related to information supplied by the Company or the Selling Stockholders and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Stockholders agree that it would not be just and equitable if contribution pursuant to this Section 2.5 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this Section 2.5(d), (a) in no case shall any one Selling Stockholder be liable or responsible for any amount in excess of the net proceeds received by such Selling Stockholder from the offering 9

of Registrable Shares and (b) the Company shall be liable and responsible for any amount in excess of such proceeds; provided, however, that no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this Section 2.5(d), notify such party or parties from whom contribution may be sought, but the omission so to notify such party or parties from whom contribution may be sought shall not relieve such party from any other obligation it may have thereunder or otherwise under this Section 2.5(d). No party shall be liable for contribution with respect to any action, suit, proceeding or claim settled without its prior written consent, which consent shall not be unreasonably withheld. 2.6 Other Matters with Respect to Underwritten Offerings. In the event that Registrable Shares are sold pursuant to a Registration Statement in an underwritten offering pursuant to Section 2.1, the Company agrees to enter into an underwriting agreement containing customary representations and warranties with respect to the business and operations of the Company and customary covenants and agreements to be performed by the Company, including without limitation customary provisions with respect to indemnification by the Company of the underwriters of such offering. 2.7 Information by Holder. Each Selling Stockholder shall furnish to the Company such information regarding such Selling Stockholder and the distribution proposed by such Selling Stockholder as the Company may reasonably request in writing and as shall be required in connection with any registration, qualification or compliance referred to in this Agreement. III. General. 3.1 Severability. The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement. 3.2 Specific Performance. In addition to any and all other remedies that may be available at law in the event of any breach of this Agreement, each Purchaser shall be entitled to specific performance of the agreements and obligations of the Company hereunder and to such other injunctive or other equitable relief as may be granted by a court of competent jurisdiction. 3.3 Transfers of Rights. The rights and obligations of the Purchasers under Section 2 may be assigned by either Purchaser to any person or entity that acquires shares of Common Stock having an aggregate value of at least $2,500,000 (as adjusted in stock splits and similar events) from such Purchaser. In the event of any such assignment, the assignee must provide written notice of 10

such assignment to the Company and agree in writing to be bound by the applicable provisions of this Agreement. 3.4 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the state of New York. 3.5 Notices.
