ITEM 5. OTHER EVENTS On April 17, 2000, Gartner Group, Inc. ("Gartner") issued and sold an aggregate of $300 million principal amount of its unsecured 6% Convertible Junior Subordinated Promissory Notes due April 17, 2005 (the "Notes") to Silver Lake Partners, L.P. and certain of Silver Lake Partners, L.P.'s affiliates. The Notes mature five years from the date of their issuance.

The initial conversion price for the Notes is $15.87.

entirety and substituting in place thereof the following:

          "SECTION 5.1 SUBSIDIARY PURCHASE RIGHTS. (a) The Company hereby grants
to the Purchasers, as defined in the Securities Purchase Agreement (such
Purchasers referred to in this Section 5.1 as the "PURCHASERS"), an option (the
"TECHREPUBLIC OPTION") to purchase up to 5.00% (as may be allocated among the
Purchasers in their discretion) of the fully diluted capital


stock of TechRepublic, Inc. ("TECHREPUBLIC") (after giving effect to all the transactions contemplated by the Agreement and Plan of Reorganization dated March 21, 2000 between the Company, TechRepublic and the other parties thereto (the "TECHREPUBLIC Agreement")) pursuant to the general terms and conditions applicable to the Company set forth in the TechRepublic Agreement and at a price which values TechRepublic at the lesser of (i) the value assigned to TechRepublic in connection with the Company's purchase, or (ii) $90.0 million. In the event TechRepublic issues to the Company any options, warrants, convertible securities or capital stock subsequent to the consummation of the transactions contemplated by the TechRepublic Agreement, the Purchasers shall receive options to purchase additional shares of TechRepublic capital stock in an amount sufficient to permit it to maintain its 5% stake of TechRepublic on a fully diluted basis (giving effect to all options, warrants or convertible securities issued to the Company on an as converted basis) at an exercise price equal to (i) the per share price received by TechRepublic in connection with such issuance or (ii) the per share exercise price or conversion price of the options, warrants or convertible securities issued, as the case may be. Prior to any contribution of assets (other than cash) by the Company to TechRepublic, the Company shall notify the Purchasers and the Company and the Purchasers shall negotiate in good faith to agree upon the value to the assets to be contributed. The Company and the Purchasers will use reasonable best efforts to enable the Company to include TechRepublic in its consolidated group for federal income tax purposes. (b) In the event that a Purchaser elects to purchase shares of the capital stock of TechRepublic during the term of this Article V, such Purchaser shall give the Company written notice of such election, which notice shall specify the number of shares of capital stock such Purchaser is electing to purchase, provided that the total number of shares of capital stock purchased by all Purchasers shall not exceed 5.00% of the fully diluted capital stock of TechRepublic (after giving effect to all of the transactions contemplated by the TechRepublic Agreement). (c) The Company hereby grants to the Purchasers the right (the "SPIN Right"; together with the TechRepublic Option, the "OPTION") to purchase up to 5.00% (as may be allocated among the Purchasers in their discretion) of the fully diluted common stock of any Subsidiary of the Company whose shares of common stock are 1) distributed to stockholders of the Company ("SPUN-OFF") or 2) sold by the Company in a public offering ("SPUN-OUT") at a per share price equal to (x) 80.0% of the initial public offering price in the case of a spun-out Subsidiary and (y) 80.0% of the first day's closing price in the case of a spun-off subsidiary. (d) In the event that the Company effects either a spun-off or spun-out subsidiary transaction during the term of this Article V, the Company shall give each Purchaser written notice of such transaction at least 30 business days prior to the consummation of the spin-off or spin-out, as the case may be.

An election by a Purchaser to

purchase shares of common stock shall be deemed to be an irrevocable commitment from such Purchaser to purchase the number of shares of common stock specified in such Purchaser's Response. If a Purchaser shall have received timely notice of a spin-off or spin-out, as the case may be, and does not provide a Response to the Company on or prior to the tenth business day prior to the consummation of the spin-off or spin-out, as the case may be, such Purchaser shall be deemed to have declined to purchase shares of common stock in such transaction." 4.

to such amount pursuant to Section 1 below, the "FACE AMOUNT") together with
interest thereon calculated from the date hereof in accordance with the

dated as of March 21, 2000 (the "AGREEMENT"), among Silver Lake Partners L.P.,
Silver Lake Investors L.P., Silver Lake Technology Investors, L.L.C. and the

corresponding increase in the then outstanding Face Amount of the Notes.

            2.    PAYMENT OF PRINCIPAL AND INTEREST ON NOTE.
                  -----------------------------------------

            (a)   SCHEDULED PAYMENT OF PRINCIPAL. The Company shall pay the Face
Amount, together with all accrued and unpaid interest thereon, if any, in cash
to the holder of this Note on April__, 2005.



(b) PAYMENT OF INTEREST. The Company shall pay interest on this Note semi-annually in arrears on March 15 and September 15 of each year, or if any such day is not a business day, on the next succeeding business day (each an "INTEREST PAYMENT DATE") to holders of record on the immediately preceding March 1 and September 1, respectively. Any interest payable on this Note shall be paid by adding an amount equal to the interest payable on such Interest Payment Date to the then outstanding Face Amount of this Note on such Interest Payment Date. Immediately following each Interest Payment Date, the Company shall deliver a written notice to the holder of this Note specifying (a) the amount of the increase to the Face Amount of this Note as a result of the interest payment on the immediately preceding Interest Payment Date and (b) the aggregate Face Amount of this Note immediately following such Interest Payment Date. (c) PRO RATA PAYMENT. The Company agrees that any payments to the holders of the Notes (including, without limitation, upon acceleration pursuant to Section 6) (whether for principal, interest or otherwise) shall be made PRO RATA among all such holders based upon the aggregate unpaid principal amount of the Notes held by each such holder. If any holder of a Note obtains any payment (whether voluntary, involuntary, by application of offset or otherwise) of principal or interest on such Note in excess of such holder's PRO RATA share of payments obtained by all holders of the Notes, such holder shall make payments to the other holders of the Notes such participation in the Notes held by them as is necessary to cause such holders to share the excess payment ratably among each of them as provided in this Section. 3. OPTIONAL REDEMPTION. ------------------- (a) OPTIONAL REDEMPTION. From and after April_, 2003, the Company, at its option, may redeem the Notes, in whole but not in part, to the extent it has funds legally available therefor and such redemption is not prohibited by the terms of its outstanding indebtedness, at the redemption price of 100% of the Face Amount thereof, plus an amount equal to the accrued and unpaid interest thereon, if any, to the redemption date; PROVIDED (i) the Current Market Price of the A Common Stock (as defined below) on the date of the notice of redemption (described below) equals or exceeds 150% of the Conversion Price (as adjusted); PROVIDED that the Closing Price of the A Common Stock on the trading day immediately preceding the date of such notice of redemption equals or exceeds 150% of the Conversion Price (as adjusted); (ii) the Company is permitted (without the necessity of any further approvals or action) by law and under the rules of any securities exchange on which the A Common Stock is traded to convert all the Notes into Shares of A Common Stock and the Company intends and has the financial resources and ability to repurchase all of the outstanding Notes; and (iii) the Company has agreed not to exercise its Cash Out Right (as defined below). As used herein, the "Current Market Price" for a given date shall mean the average Closing Price of the A Common Stock as reported in THE WALL STREET JOURNAL or, at the election of the Company, other reputable financial news source, for the 20 consecutive trading days immediately preceding the date the redemption notice is given. As used herein, the "Closing Price" of any security on any day means the last reported sale price regular way on such day or, in the case no such sale takes place on such day, the average of the reported closing bid and asked prices regular way of the Common Stock, in each case on the NYSE or, if not listed or admitted to trading on such exchange, as quoted on AMEX or Nasdaq.

(b) PAYMENT OF REDEMPTION PRICE. --------------------------- (i) The amount of the redemption price on the Notes redeemed, on any redemption set forth herein, shall be paid to the holders of the Notes in cash (to the extent funds are legally available therefor and such redemption is not prohibited by the terms of its outstanding indebtedness). (ii) Not less than 15 days nor more than 45 days (such date as fixed by the board of directors of the Company is referred to herein as the "REDEMPTION RECORD DATE") prior to the date fixed for any redemption of the Notes pursuant to this Section 3, a notice specifying the time and place of the redemption of the Notes shall be given by first class mail, postage prepaid, to the holders of record on the Redemption Record Date of the Notes to be redeemed at their respective addresses as the same shall appear on the books of the Company, calling upon each holder of record to surrender to the Company on the redemption date at the place designated in the notice the Notes owned by such holder. Neither failure to mail such notice, nor any defect therein or in the mailing thereof, to any particular holder shall affect the sufficiency of the notice or the validity of the proceedings for redemption with respect to the other holders. On or after the redemption date, each holder of Notes to be redeemed shall present and surrender such holder's Notes to the Company at the place designated in the redemption notice and thereupon the redemption price of the Notes, and any unpaid interest thereon to the redemption date, shall be paid to or on the order of the person whose name appears in the Note Register (as herein defined) as the owner thereof, and each surrendered Note shall be canceled by the Company. (iii) If a notice of redemption has been given pursuant to this Section 3 and if, on or before the redemption date, the funds necessary for such redemption (including all interest on the Notes to be redeemed that will accrue to the redemption date) shall have been set aside by the Company, separate and apart from its other funds, in trust for the benefit of the holders of all the Notes, then, notwithstanding that any Notes have not been surrendered for cancellation, on the redemption date interest shall cease to accrue on the Notes to be redeemed, and at the close of business on the date on which such funds have been segregated and set aside by the Company as provided in this Subsection 3(b)(iii), the holders of the Notes shall have no rights with respect thereto, except the conversion rights provided in subsection (iv) of this Section 3(b) and Section 4 below and the right to receive the moneys payable upon such redemption, without interest thereon, upon surrender of their Notes. (iv) If a notice of redemption has been given pursuant to this Section 3 and any holder of Notes shall, prior to the close of business on the business day immediately preceding the redemption date, give written notice to the Company pursuant to Section 4 below of the conversion of any or all of the Notes to be redeemed held by the holder (accompanied by the Note or Notes), then such redemption shall not become effective as to such Notes to be converted and such conversion shall become effective as provided in Section 4 below, whereupon any funds deposited by the Company for the redemption of such notes shall (subject to any right of the holder of such Notes to receive the interest payable thereon as provided in Section 4 below) immediately upon such conversion be returned to the Company or, if then held in trust by the

Company, shall automatically and without further corporate action or notice be discharged from the trust. 4. CONVERSION RIGHTS. ----------------- The holders of the Notes shall have conversion rights as follows (the "CONVERSION RIGHTS"): (a) RIGHT TO CONVERT. ---------------- (i) Following April__, 2003 and provided that all filings made under the Hart-Scott-Rodino Anti-Trust Improvements Act of 1976, as amended, as required by Section 6.1 of the Securityholders Agreement dated the date hereof (as such agreement may be amended, supplemented or otherwise modified from time to time, the "SECURITYHOLDERS Agreement") have been made and all related waiting periods have expired or have been terminated early, the Face Amount of this Note plus all accrued and unpaid interest thereon shall be convertible, in whole or in part, at the option of the holder thereof, at any time and from time to time, subject to compliance with this Section 4, into fully paid and nonassessable shares of the Company's Class A Common Stock, par value $.005 per share (the "A COMMON STOCK"; and together with Company's Class B Common Stock, par value $.005 per share, the "COMMON STOCK") at the then effective Conversion Rate (as defined below) (each such conversion, an "OPTIONAL CONVERSION"). The Conversion Rate, as of any date of determination, shall equal an amount determined by dividing (i) the Face Amount outstanding on such date, plus any accrued and unpaid interest on such Notes, by (ii) the Conversion Price (as defined below) in effect as of any date of determination. The Conversion Price at which shares of Common Stock shall be deliverable upon conversion of the Notes without the payment of additional consideration by the holder thereof (the "CONVERSION PRICE") shall initially be $15.87. Such initial Conversion Price and the rate at which the Notes may be converted into shares of A Common Stock, shall be subject to adjustment as provided below. (ii) Notwithstanding a holder's request to convert all or part of his or her Notes into A Common Stock, the Company shall, except following the Company's exercise of its option pursuant Section 3, have the right (the "CASH OUT RIGHT") after such request to redeem all, but not part of, such Notes for cash in an amount equal to the product of (x) the quotient of (i) the Face Amount of the Notes to be converted and (ii) the Conversion Price and (y) the Closing Price on the day the holder delivered written notice to the Company of its election to convert all or part of such holder's Notes into A Common Stock. (b) FRACTIONAL SHARES. No fractional shares of A Common Stock shall be issued upon conversion of the Notes. In lieu of fractional shares, the Company shall pay cash equal to such fraction multiplied by the Closing Price for shares of A Common Stock on the trading date immediately preceding the related Conversion Date. (c) MECHANICS OF CONVERSION. -----------------------

(i) In order to convert Notes into shares of A Common Stock, the holder shall deliver written notice to the Company that such holder elects to convert all or part of the Face Amount represented by such Note or Notes. Such notice shall state the Face Amount of Notes which the holder seeks to convert. The date of receipt of the Note or Notes by the Company shall be the conversion date ("CONVERSION DATE"). As soon as practicable (but no later than two days) after the Conversion Date, the Company shall promptly issue and deliver at such office to such holder a certificate or certificates for the number of shares of A Common Stock to which such holder is entitled and, in the case where only part of a Note is converted, the Company shall execute and deliver (at its own expense) a new Note of any authorized denomination as requested by a holder in an aggregate principal amount equal to and in exchange for the unredeemed portion of the principal amount of the Note so surrendered. Such conversion shall be deemed to have been made at the close of business on the date of such surrender of the Notes to be converted, and the holder entitled to receive the shares of A Common Stock issuable upon such conversion shall be treated for all purposes as the record holder of such shares of A Common Stock on such date. (ii) The Company shall at all times during which the Notes shall be outstanding, reserve and keep available out of its authorized but unissued stock, for the purpose of effecting the conversion of the Notes, such number of its duly authorized shares of A Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding Notes. In addition, the Company shall at all times during which the Notes shall be outstanding, reserve and keep available out of its authorized but unissued stock, for the purpose of effecting the conversion of the Notes, such number of its duly authorized shares of preferred stock as shall from time to time be sufficient to effect the conversion of all outstanding Notes into Preferred Stock, if necessary. Before taking any action which would cause an adjustment reducing the Conversion Price below the then par value of the shares of A Common Stock issuable upon conversion of the Notes, the Company will take any corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock at such adjusted Conversion Price. (iii) All Notes which shall have been surrendered for conversion as herein provided shall no longer be deemed to be outstanding and all rights with respect to such Notes, including the rights, if any, to receive interest, notices and consent rights shall immediately cease and terminate on the Conversion Date, except only the right of the holders thereof to receive shares of A Common Stock, cash or Preferred Stock, as the case may be, in exchange therefor, and, if applicable, cash for any fractional shares of A Common Stock. Any Notes so converted shall be retired and canceled. (iv) If the conversion is in connection with an underwritten offering of securities registered pursuant to the Securities Act of 1933, as amended, the conversion may, at the option of any holder tendering Notes for conversion, be conditioned upon the closing with the underwriter of the sale of securities pursuant to such offering, in which event the holders entitled to receive the A Common Stock issuable upon such conversion of the Notes shall not be deemed to have converted such Notes until immediately prior to the closing of the sale of securities.

(d) ADJUSTMENTS TO CONVERSION PRICE FOR DILUTING ISSUES. --------------------------------------------------- (i) SPECIAL DEFINITIONS. For purposes of this Subsection 4(d), the following definitions shall apply: (A) "Option" shall mean Rights, options or warrants to subscribe for, purchase or otherwise acquire Common Stock or Convertible Securities, other than such Rights, options or warrants granted to employees, directors or consultants of the Company pursuant to plans or arrangements approved by the Company's board of directors. (B) "Convertible Securities" shall mean any evidences of indebtedness, shares or other securities directly or indirectly convertible into or exchangeable for Common Stock. (C) "Additional Shares of Common Stock" shall mean all shares of Common Stock issued (or, pursuant to Subsection 4(d)(ii) below, deemed to be issued) by the Company after April__, 2000 (the "Issue Date"). (D) "Rights to Acquire Common Stock" (or "RIGHTS") shall mean all rights issued by the Company to acquire Common Stock whether by exercise of a warrant, option or similar call, or conversion of any existing instruments, in either case for consideration fixed, in amount or by formula, as of the date of issuance. (ii) ISSUE OF SECURITIES DEEMED ISSUE OF ADDITIONAL SHARES OF COMMON STOCK. If the Company at any time or from time to time after the Issue Date issues any Options or Convertible Securities or Rights to Acquire Common Stock, then the maximum number of shares of Common Stock (as set forth in the instrument relating thereto without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options, Rights to Acquire Common Stock or, in the case of Convertible Securities, the conversion or exchange of such Convertible Securities, shall be deemed to be Additional Shares of Common Stock issued as of the time of such issue; provided, however, that in any such case: (A) No further adjustment in the Conversion Price shall be made upon the subsequent issue of shares of Common Stock upon the exercise of such Options, Rights or conversion or exchange of such Convertible Securities; (B) Upon the expiration or termination of any unexercised Option, Right or Convertible Security, the Conversion Price shall be adjusted immediately to reflect the applicable Conversion Price which would have been in effect had such Option, Right or Convertible Security (to the extent outstanding immediately prior to such expiration or termination) never been issued; and

(C) In the event of any change in the number of shares of Common Stock issuable upon the exercise, conversion or exchange of any Option, Right or Convertible Security, including, but not limited to, a change resulting from the anti-dilution provisions thereof, the Conversion Price then in effect shall forthwith be readjusted to such Conversion Price as would have obtained had the Conversion Price adjustment that was originally made upon the issuance of such Option, Right or Convertible Security which were not exercised or converted prior to such change been made upon the basis of such change, but no further adjustment shall be made for the actual issuance of Common Stock upon the exercise or conversion of any such Option, Right or Convertible Security. (iii) ADJUSTMENT OF CONVERSION PRICE UPON ISSUANCE OF ADDITIONAL SHARES OF COMMON STOCK. (a) If the Company shall at any time after the Issue Date issue Additional Shares of Common Stock (including Additional Shares of Common Stock deemed to be issued pursuant to Subsection 4(d)(ii), but excluding shares issued as a dividend or distribution as provided in subsection 4(f) or upon a stock split or combination as provided in subsection 4(e)), without consideration, or for a consideration per share less than the Fair Market Value per share of Common Stock on the date of and immediately prior to such issue, then and in such event, the Conversion Price shall be reduced, concurrently with such issuance, to a price (calculated to the nearest cent) determined by multiplying such Conversion Price by a fraction, the numerator of which shall be the sum of (A) the number of shares of Common Stock outstanding, on a fully diluted basis, immediately prior to such issuance plus (B) the number of shares of Common Stock which the aggregate consideration received by the Company for the total number of Additional Shares of Common Stock so issued would purchase at the Fair Market Value per share of Common Stock and the denominator of which shall be the sum of (1) the number of shares of Common Stock outstanding immediately prior to such issuance plus (2) the number of such Additional Shares of Common Stock so issued. (b) If the Company shall at any time after the Issue Date issue Additional Shares of Common Stock (including Additional Shares of Common Stock deemed to be issued pursuant to Subsection 4(d)(ii), but excluding shares issued as a dividend or distribution as provided in subsection 4(f) or upon a stock split or combination as provided in subsection 4(e)) for a consideration per share less than the Conversion Price (as adjusted) on the date of and immediately prior to such issue, then and in such event, the Conversion Price shall be reduced, concurrently with such issuance, to a price (calculated to the nearest cent) determined by multiplying such Conversion Price by a fraction, the numerator of which shall be the sum of (A) the number of shares of Common Stock outstanding, on a fully diluted basis, immediately prior to such issuance plus (B) the number of shares of Common Stock which the aggregate consideration received by the Company for the total number of Additional Shares of Common Stock so issued would purchase if the amount paid for such shares was equal to the Conversion Price and the denominator of which shall be the sum of (1) the number of shares of Common Stock outstanding

immediately prior to such issuance plus (2) the number of such Additional Shares of Common Stock so issued. (c) If the Company shall at any time after the Issue Date issue Additional Shares of Common Stock (including Additional Shares of Common Stock deemed to be issued pursuant to Subsection 4(d)(ii), but excluding shares issued as a dividend or distribution as provided in subsection 4(f) or upon a stock split or combination as provided in subsection 4(e)) for a consideration per share that is less than the Fair Market Value and less than the Conversion Price (as adjusted), in each case on the date of and immediately prior to such issue, then and in such event, the Conversion Price shall be reduced, to equal the lesser of (a) the Conversion Price as adjusted pursuant to Section 4(d)(iii)(a) or (b) the Conversion Price as adjusted pursuant to Section 4(d)(iii)(b). Notwithstanding the foregoing, the applicable Conversion Price shall not be reduced if the amount of such reduction would be an amount less than $.01, but any such amount shall be carried forward and reduction with respect thereto made at the time of and together with any subsequent reduction which, together with such amount and any other amount or amounts so carried forward, shall aggregate $.01 or more. (iv) DETERMINATION OF CONSIDERATION. For purposes of this Subsection 4(d), "Fair Market Value" of the consideration received by the Company for the issue of any Additional Shares of Common Stock shall be computed as follows: (A) CASH AND PROPERTY. Such consideration shall: ----------------- (1) insofar as it consists of cash, be computed at the aggregate of cash received by the Company, excluding amounts paid or payable for accrued interest or accrued dividends; (2) insofar as it consists of property other than cash, be computed at the Fair Market Value thereof at the time of such issue, as determined in good faith by the Board (absent manifest error); and (3) in the event Additional Shares of Common Stock are issued together with other shares or securities or other assets of the Company for consideration which covers both, be the proportion of such consideration so received, computed as provided in clauses (1) and (2) above, as determined in good faith by the Board (absent manifest error). (B) OPTIONS, RIGHTS AND CONVERTIBLE SECURITIES. The consideration per share received by the Company for Additional Shares of Common Stock deemed to have been issued pursuant to subsection 4(d)(ii), relating to Options, Rights and Convertible Securities, shall be determined by dividing

(1) the total amount, if any, received or receivable by the Company as consideration for the issue of such Options, Rights or Convertible Securities, plus the minimum aggregate amount of additional consideration (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such consideration) payable to the Company upon the exercise of such Options, Rights or the conversion or exchange of such Convertible Securities, by (2) the maximum number of shares of Common Stock (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options, Rights or the conversion or exchange of such Convertible Securities. (e) ADJUSTMENT FOR STOCK SPLITS AND COMBINATIONS. If the Company shall at any time or from time to time after the Issue Date effect a subdivision of the outstanding Common Stock, the Conversion Price then in effect immediately before that subdivision shall be proportionately decreased. If the Company shall at any time or from time to time after the Issue Date combine the outstanding shares of Common Stock, the Conversion Price then in effect immediately before the combination shall be proportionately increased. Any adjustment under this paragraph shall become effective at the close of business on the date the subdivision or combination becomes effective. (f) ADJUSTMENT FOR CERTAIN DIVIDENDS AND DISTRIBUTIONS. In the event the Company at any time or from time to time after the Issue Date shall make or issue a dividend or other distribution payable in Additional Shares of Common Stock, then and in each such event the Conversion Price shall be decreased as of the time of such issuance, by multiplying such Conversion Price by a fraction, the numerator of which shall be the total number of shares of Common Stock outstanding, on a fully diluted basis, immediately prior to such issuance and the denominator of which shall be the total number of shares of Common Stock outstanding immediately prior to such issuance plus the number of such Additional Shares of Common Stock issuable in payment of such dividend or distribution. (g) ADJUSTMENTS FOR OTHER DIVIDENDS AND DISTRIBUTIONS. In the event the Company at any time, or from time to time after the Issue Date shall make or issue, a dividend or other distribution payable in securities of the Company (other than shares of Common Stock) or other assets or properties, then and in each such event provision shall be made so that the holders of the Notes shall receive in addition to the number of shares of A Common Stock receivable upon conversion of the Notes, the amount of securities of the Company or other assets or properties that they would have received had their Notes been converted into A Common Stock on the date of such event and had thereafter, during the period from the date of such event to and including the Conversion Date, retained such securities or other assets or properties receivable by them as aforesaid during such period giving application to all adjustments called for during such period, under this paragraph with respect to the rights of the holders of the Notes; provided that,

in the event rights or benefits under such securities, assets or properties shall terminate prior to the time that the holder of this Note may elect to convert this Note into shares of A Common Stock, such amount of securities, assets or properties that the holder would have received had such holder converted his or her notes immediately prior to the distribution shall be distributed to the holder of this Note on the date the securities, assets or properties are distributed to the holders of Common Stock. (h) ADJUSTMENT FOR RECLASSIFICATION, EXCHANGE OR SUBSTITUTION. If the A Common Stock issuable upon the conversion of the Notes shall be changed into the same or a different number of shares of any class or classes of stock, whether by capital reorganization, reclassification, or otherwise (other than a subdivision or combination of shares, stock dividend or reorganization, reclassification, merger, consolidation or asset sale provided for elsewhere in this Section 4), then and in each such event the holder of each Note (whether then outstanding or thereafter issued) shall have the right thereafter to convert such Note into the kind and amount of shares of stock and other securities and property receivable upon such reorganization, reclassification, or other change, by holders of the number of shares of A Common Stock into which all such Notes might have been converted immediately prior to such reorganization, reclassification, or change, all subject to further adjustment as provided herein or with respect to such other securities or property by the terms thereof. (i) REORGANIZATIONS, MERGERS, CONSOLIDATIONS OR ASSET SALES. If at any time after the Issue Date there is a merger, consolidation, recapitalization, sale of all or substantially all of the Company's assets or reorganization involving the A Common Stock (collectively, a "CAPITAL REORGANIZATION") (other than a merger, consolidation, sale of assets, recapitalization, subdivision, combination, reclassification, exchange or substitution of shares provided for elsewhere in this Section 4), as part of such Capital Reorganization, provision shall be made so that the holders of Notes (whether then outstanding or thereafter issued) will thereafter be entitled to receive upon conversion of the Notes the number of shares of stock or other securities or property of the Company to which a holder of the number of shares of A Common Stock deliverable upon conversion would have been entitled on such Capital Reorganization, subject to adjustment in respect to such stock or securities by the terms thereof. In any such case, appropriate adjustment will be made in the application of the provisions of this Section 4 with respect to the rights of the holders of Notes after the Capital Reorganization to the end that the provisions of this Section 4 (including adjustment of the Conversion Price then in effect and the number of shares issuable upon conversion of the Notes) will be applicable after that event and be as nearly equivalent as practicable. In the event that the Company is not the surviving entity of any such Capital Reorganization, each Note shall become Notes of such surviving entity, with the same powers, rights and preferences as provided herein. (j) FIRST ANNIVERSARY CONVERSION PRICE RESET. If the average Closing Price of the A Common Stock for the 30 trading days immediately preceding the first anniversary of the Issue Date (the "30-DAY AVERAGE") is below 90.91% of the Conversion Price then in effect, the Conversion Price shall be reset to a lower amount that represents a 10.00% premium to the 30-Day Average (the "FIRST ANNIVERSARY RESET"). In the event that the Conversion Price is subject to downward adjustment due to the First Anniversary Reset, the Company shall have the option to

redeem the Notes in whole, but not in part (except as provided in the following sentence), for such consideration equal to 125% of the then outstanding Face Amount of this Note (the "REFINANCING RIGHT"); PROVIDED HOWEVER, prior to the Company's exercise of the Refinancing Right, the holders of the Notes shall receive reasonable notice from the Company of its election to exercise its Refinancing Right and each holder shall have the right for a period of ten business days to waive in writing the First Anniversary Reset and to continue to hold the Notes with the Conversion Price then in effect. The Company shall have a refinancing right with respect to each Note the holder of which does not agree to waive the First Anniversary Reset, and in the event that holders of a majority of the aggregate principal amount of outstanding Notes elect to have the Conversion Price adjusted to the First Anniversary Reset amount, the Company shall have the right to repurchase all of the outstanding Notes at 125% of the then outstanding Face Amount of the Notes. If the Company exercises the Refinancing Right, and the holders of the Notes elect not to waive the First Anniversary Reset, the Company must complete the redemption of the Notes within twenty business days from the date the Company's notice was given; PROVIDED FURTHER, if the Company fails to complete the redemption as described above, the Conversion Price shall be immediately adjusted downward as provided for the First Anniversary Reset. (k) NO IMPAIRMENT. The Company will not, by amendment of its Certificate of Incorporation or through any reorganization, 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 will at all times in good faith assist in the carrying out of all the provisions of this Section 4 and in the taking of all such action as may be necessary or appropriate in order to protect the conversion rights of the holders of the Notes against impairment to the extent required hereunder. Nothing in this Section 4 shall affect the continued accrual of interest on the Notes in accordance with the terms of this Note. (l) CERTIFICATE AS TO ADJUSTMENTS. Upon the occurrence of each adjustment or readjustment of the Conversion Price pursuant to this Section 4, the Company at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to each holder, if any, of Notes outstanding a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based and shall file a copy of such certificate with its corporate records. The Company shall, upon the reasonable written request of any holder of Notes, furnish or cause to be furnished to such holder a similar certificate setting forth (i) such adjustments and readjustments, (ii) the Conversion Price then in effect, and (iii) the number of shares of A Common Stock and the amount, if any, of other property which then would be received upon the conversion of Notes. Despite such adjustment or readjustment, the form of each or all Notes, if the same shall reflect the initial or any subsequent Conversion Price, need not be changed in order for the adjustments or readjustments to be valid in accordance with the provisions of this Note, which shall control. (m) NOTICE OF RECORD DATE. In the event --------------------- (i) that the Company declares a dividend (or any other distribution) on its Common Stock payable in Common Stock or other securities of the Company;

REPURCHASE RIGHT UPON A CHANGE OF CONTROL. ----------------------------------------- (a) In the event that a Change in Control (as herein defined) shall occur, then each holder shall have the right (the "REPURCHASE RIGHT"), at the holder's option to require the Company to repurchase, and upon the exercise of such right the Company shall repurchase, all of such holder's Notes, or any portion of the principal amount thereof that is equal to $1,000 or any integral multiple thereof, on the date (the "Repurchase Date") that is 30 days after the date of the Company Notice (as defined in subsection (b) of this Section 5) at a purchase price equal to 101% of the Face Amount to be repurchased plus accrued and unpaid interest thereon, if any, to the Repurchase Date (the "REPURCHASE Price"). "CHANGE IN CONTROL" means (a) the acquisition of ownership, directly or indirectly, beneficially or of record, by any Person or group (within the meaning of Rule 13d-5 under the Securities Exchange Act of 1934 as in effect on the date hereof) of shares representing more than 35% of the aggregate ordinary voting power represented by the issued and outstanding Common Stock; (b) occupation of a majority of the seats (other than vacant seats) on the board of directors of the Company by Persons who were neither (i) nominated by the board of directors of the Company nor (ii) appointed by directors so nominated;

(b) On or before the 20th day after the occurrence of a Change in Control, the Company shall give to all holders of Notes notice (the "Company Notice"), of the occurrence of the Change in Control and of the Repurchase Right set forth herein arising as a result thereof. Each notice of a repurchase right shall be mailed to the holders of the Notes at their last address as shown on the records of the Company and shall state: (i) the Repurchase Date; (ii) the date by which the repurchase right must exercised; (iii) the Repurchase Price; (iv) a description of the procedure which a Holder must follow to exercise a repurchase right, and the place or places where such Notes, are to be surrendered for payment of the Repurchase Price; (v) that on the Repurchase Date the Repurchase Price will become due and payable upon each such Note designated by the Holder to be repurchased, and that interest thereon shall cease to accrue on and after said date; (vi) the Conversion Rate then in effect, the date on which the right to convert the principal amount of the Notes to be repurchased will terminate and the place where such Notes may be surrendered for conversion; and (vii) the place or places that the Notes with the option to elect repayment upon a change of control shall be delivered. No failure of the Company to give the foregoing notices or defect therein shall limit any holder's right to exercise a Repurchase Right or affect the validity of the proceedings for the repurchase of Securities. If any of the foregoing provisions or other provisions of this Section 5 are inconsistent with applicable law, such law shall govern. (c) To exercise a Repurchase Right, a holder shall deliver to the Company on or before the 30th day after the date of the Company Notice (i) written notice of the holder's exercise of such right, which notice shall set forth the name of the holder, the principal amount of the Notes to be repurchased (and, if any Note is to be repurchased in part, the serial number thereof, the portion of the principal amount thereof to be repurchased is to be registered) and a statement that an election to exercise the Repurchase Right is being made thereby, and (ii) the

Notes with respect to which the Repurchase Right is being exercised. Such written notice shall be irrevocable, except that the right of the Holder to convert the Notes with respect to which the Repurchase Right is being exercised shall continue until the close of business on the business day immediately preceding the Repurchase Date. (d) In the event a Repurchase Right shall be exercised in accordance with the terms hereof, the Company shall pay or cause to be paid to the holders of Notes the Repurchase Price in cash as promptly after the Repurchase Date as practicable, together with accrued and unpaid interest to the Repurchase Date payable with respect to the Notes as to which the repurchase right has been exercised. (e) If any Note (or portion thereof) surrendered for repurchase shall not be so paid on the Repurchase Date, the principal amount of such Note (or portion thereof, as the case may be) shall, until paid, bear interest to the extent permitted by applicable law from the Repurchase Date at the rate of 9% per annum, and each Note shall remain convertible into Common Stock until the principal of such Note (or portion thereof, as the case may be) shall have been paid or duly provided for. (f) Any Note which is to be repurchased only in part shall be surrendered to the Company and the Company shall execute and make available for delivery to the holder of such Note without service charge, a new Note or Notes, containing identical terms and conditions, each in an authorized denomination in aggregate principal amount equal to and in exchange for the unrepurchased portion of the principal of the Note so surrendered. 6. EVENTS OF DEFAULT. ----------------- (a) DEFINITION.

(b) CONSEQUENCES OF EVENTS OF DEFAULT. ---------------------------------

(i) Subject to the provisions of Section 11 of this Note, if an Event of Default of the type described in subsections 6(a)(i), (iii), (iv), (v) and (vi) has occurred and continued for 15 days or any other Event of Default has occurred, the holder or holders of the Notes representing a majority of the aggregate principal amount then outstanding of the Notes may declare all or any portion of the outstanding principal amount of the Notes due and payable and demand immediate payment of all or any portion of the outstanding principal amount of the Notes owned by such holder or holders, PROVIDED that in an Event of Default specified in subsection 6(a)(ii), all of the outstanding principal amount of the Notes shall automatically and immediately become due and payable. The Company shall give prompt written notice of any such demand to the other holders, if any, of any portion of the Notes, each of which may demand immediate payment of all or any portion of such holder's portion of the Notes.

WAIVERS. The Company hereby waives presentment, demand, notice, protest and all other demands and notices in connection with the delivery, acceptance, performance, default or enforcement of this Note. 11. SUBORDINATION. The Company agrees, and by the acceptance hereof each holder agrees, as follows: (a) SUBORDINATION OF LIABILITIES. The Company, for itself, its successors and assigns, covenants and agrees, and each holder of this Note (together with its successors and assigns, the "holder of this Note") by its acceptance hereof likewise covenants and agrees, that the payment of the principal of, interest on, and all other amounts owing in respect of, this Note (the "SUBORDINATED INDEBTEDNESS") is hereby expressly subordinated, to the extent and in the manner hereinafter set forth, to the prior payment in full in cash of all Senior Indebtedness. The provisions of this Section 11, and the provisions of Sections 2 and 6 of this Note, each shall constitute a continuing offer to all persons or other entities who, in reliance upon such provisions, become holders of, or continue to hold, Senior Indebtedness, and such provisions are made for the benefit of the holders of Senior Indebtedness, and such holders are hereby made obligees hereunder the same as if their names were written herein as such and they and/or each of them may proceed to enforce such provisions. (b COMPANY NOT TO MAKE PAYMENTS WITH RESPECT TO SUBORDINATED INDEBTEDNESS IN CERTAIN CIRCUMSTANCES. (i) In the event of a Senior Payment Default (as hereinafter defined), then, upon receipt by the Company and the holders of Subordinated Indebtedness of written notice of such Senior Default (a "SENIOR PAYMENT DEFAULT NOTICE") from either (i) the Administrative Agent (as defined in the Credit Agreement) if such Senior Payment Default relates to the Credit Agreement or any replacement thereof or (ii) the holders of at least a majority in principal amount of outstanding Senior Indebtedness to which such Senior Payment Default relates or any duly authorized representative of such holders, no payment (other than a payment in the form of any other indebtedness of the Company which is subordinated to the payment of the Senior Indebtedness to the same extent as this Note is subordinated to the Senior Indebtedness or payments made in equity securities of the Company, including as a result of the conversion of the Noes into Shares of A Common Stock) shall be made by the Company on account of principal of (or premium, if any) or interest on the Subordinated Indebtedness unless and until (i) such Senior Payment Default shall have been cured or waived or shall have ceased to exist or (ii) all amounts then due and payable in respect of Senior Indebtedness shall have been paid in full in cash, or provision shall have been made for such payment and all commitments to make further loans, advances and other credit accommodations under the Credit Agreement or such other Senior Indebtedness have been terminated (such period during which a Senior Default continues being, a "PAYMENT DEFAULT BLOCKAGE PERIOD").

(ii) In the event that any Senior Nonmonetary Default (as hereinafter defined) shall have occurred and be continuing, then, upon the receipt by the Company and the holders of Subordinated Indebtedness of written notice of such Senior Nonmonetary Default (a "SENIOR NONMONETARY DEFAULT NOTICE") from either (i) the Administrative Agent if such Senior Nonmonetary Default relates to the Credit Agreement or any replacement thereof or (ii) the holders of a majority in principal amount of outstanding Senior Indebtedness to which such Senior Nonmonetary Default relates or any duly authorized representative of such holders, no payment (other than a payment in the form of any other indebtedness of the Company which is subordinated to the payment of the Senior Indebtedness to the same extent as the Note is subordinated to the Senior Indebtedness or payments made in equity interests of the company, including as a result of the conversion of the Notes into Shares of A Common Stock) shall be made by the Company on account of principal of (or premium, if any) or interest on the Subordinated Indebtedness during the period (the "NONMONETARY DEFAULT BLOCKAGE PERIOD") commencing on the date of receipt of such Senior Nonmonetary Default Notice and ending on the earlier of (a) the date on which such Senior Nonmonetary Default shall have been cured or waived or shall have ceased to exist and any acceleration of Senior Indebtedness shall have been rescinded or annulled or the Senior Indebtedness to which such Senior Nonmonetary Default relates shall have been discharged or (b) the 179th day after the date of receipt of such written notice; PROVIDED, HOWEVER, that not more than one Senior Nonmonetary Default Notice shall be given during any period of 360 consecutive days, regardless of the number of defaults with respect to Senior Indebtedness during such 360-day period. For all purposes of this Section 11(b)(ii), no event of default which existed or was continuing on the date of commencement of any Nonmonetary Default Blockage Period with respect to any Senior Indebtedness shall be, or be made, the basis for the commencement of a another Nonmonetary Default Blockage Period by the holders (or any duly authorized agent or other representative thereof) of such Senior Indebtedness whether or not within a period of 360 consecutive days, unless such event of default shall have been cured or waived for a period of not less than 90 consecutive days (it being acknowledged that any subsequent action, or any breach of any financial covenants for a period commencing after the date of commencement of such Nonmonetary Default Blockage Period that, in either case, would give rise to an event of default pursuant to any provisions under which an event of default previously existed or was continuing shall constitute a new event of default for this purpose). (iii) If an Event of Default shall occur and be continuing at any time during the continuance of a Payment Default Blockage Period or a Nonmonetary Default Blockage Period, no holder of Subordinated Indebtedness shall ask, demand or sue for any payment or distribution or seek any other remedy in respect of the Subordinated Indebtedness or commence or join in with any other creditor (other than the agent for the holders of Senior Indebtedness) in commencing any bankruptcy, insolvency, receivership or similar proceedings prior to the earliest to occur of (i) acceleration of any Senior Indebtedness or any other exercise of remedies by the Administrative Agent or the Lenders (as defined in the Credit Agreement) or the other holders of Senior Indebtedness, including without

limitation, any realization on collateral or any reduction of commitments as a result of the occurrence and continuance of any event of default under the Credit Agreement or any agreement or instrument evidencing Senior Indebtedness, (ii) the occurrence of an Event of Default specified in Sections 6(a)(ii) hereof or (iii) the earlier to occur of (x) 179 days after the commencement of such Payment Blockage Period or Nonmonetary Blockage Period or (y) the expiration of such Payment Blockage Period or Nonmonetary Default Blockage Period. (iv) Except as contemplated by Section 2(b) and Section 4, the Company may not, directly or indirectly, make any payment of any kind or character of any Subordinated Indebtedness and may not acquire any Subordinated Indebtedness for cash or property until all Senior Indebtedness has been paid in full in cash if such payment is prohibited by the terms of any Senior Indebtedness or if any default or event of default under any Senior Indebtedness is then in existence or would result therefrom. (v) In the event that, notwithstanding the other provisions of this Section 11(b), the Company shall make (or any other person or entity on behalf of the Company shall make) any payment on account of the Subordinated Indebtedness (other than as contemplated by Section 2(b) and Section 4) or shall acquire any Subordinated Indebtedness for cash or property at a time when payment is not permitted by such provisions, such payment shall be held by the holder of this Note, in trust for the benefit of, and shall be paid forthwith over and delivered to, the holders of Senior Indebtedness or their representative, agent or trustee under the loan agreement, indenture or other agreement pursuant to which any instruments evidencing any Senior Indebtedness may have been issued, as their respective interests may appear, for application PRO RATA to the payment of all Senior Indebtedness remaining unpaid to the extent necessary to pay all Senior Indebtedness in full in cash in accordance with the terms of such Senior Indebtedness, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness. Without in any way modifying the provisions of this Section 11 or affecting the subordination effected hereby, if notice has not been previously given, the Company shall give the holder of this Note prompt written notice of any event which would prevent payments under this Section 11(b). (c) SUBORDINATION TO PRIOR PAYMENT OF ALL SENIOR INDEBTEDNESS ON DISSOLUTION, LIQUIDATION OR REORGANIZATION OF THE COMPANY. Upon any payment or distribution of assets of the Company of any kind or character (whether in cash, properties or securities) upon any total or partial dissolution, winding up, liquidation or reorganization of the Company (whether in bankruptcy, insolvency, receivership or similar proceedings or upon an assignment for the benefit of creditors, marshaling of assets of the Company or otherwise): (i) the holders of all Senior Indebtedness shall first be entitled to receive payment in full in cash of all Senior Indebtedness (including, without limitation, post-petition interest at the rate provided in the documentation with

respect to such Senior Indebtedness, whether or not such post- petition interest is an allowed claim against the debtor in any bankruptcy or similar proceeding) before the holder of this Note is entitled to receive any payment of any kind or character on account of the Subordinated Indebtedness other than equity securities of the Company or debt securities that are subordinated to the Senior Indebtedness to substantially the same extent as, or to a greater extent than, the Notes are subordinated to Senior Indebtedness; (ii) any payment or distribution of assets of the Company of any kind or character (other than equity securities of the Company or debt securities that are subordinated to the Senior Indebtedness to substantially the same extent as, or to a greater extent than, the Notes are subordinated to Senior Indebtedness), whether in cash, property or securities to which the holder of this Note would be entitled except for the provisions of this Section 11, shall be paid by the liquidating trustee or agent or other person making such payment or distribution, whether a trustee in bankruptcy, a receiver or liquidating trustee or other trustee or agent, directly to the holders of Senior Indebtedness or their representative, agent or trustee under any loan agreement, indenture or other agreement under which any instruments evidencing any such Senior Indebtedness may have been issued, to the extent necessary to make payment in full in cash of all Senior Indebtedness remaining unpaid, after giving effect to any concurrent payment or distribution to the holders of such Senior Indebtedness; and (iii) in the event that, notwithstanding the foregoing provisions of this Section 11(c), any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, shall be received in violation hereof by the holder of this Note on account of Subordinated Indebtedness before all Senior Indebtedness is paid in full in cash, such payment or distribution shall be received and held in trust for and shall be paid over to the holders of the Senior Indebtedness remaining unpaid or their representative, agent or trustee under any loan agreement, indenture or other agreement under which any instruments evidencing any of such Senior Indebtedness may have been issued, for application to the payment of such Senior Indebtedness until all such Senior Indebtedness shall have been paid in full in cash after giving effect to any concurrent payment or distribution to the holders of such Senior Indebtedness. To the extent any payment of Senior Indebtedness (whether by or on behalf of the Company, as proceeds of security or enforcement of any right of setoff or otherwise) is declared to be fraudulent or preferential, set aside or required to be paid to any receiver, trustee in bankruptcy, liquidating trustee, agent or other similar person under any bankruptcy, insolvency, receivership, fraudulent conveyance or similar law, then, if such payment is recovered by, or paid over to, such receiver, trustee in bankruptcy, liquidating trustee, agent or other similar person, the Senior Indebtedness or part thereof originally intended to be satisfied shall be deemed to be reinstated and outstanding as if such payment has not occurred. If the holder of this Note does not file a proper claim or proof of debt in the form required in any bankruptcy, insolvency,

receivership, reorganization or similar proceeding prior to 30 days before the expiration of the time to file such claim or claims, then any of the holders of the Senior Indebtedness or their representative, agent or trustee is hereby authorized to file an appropriate claim for and on behalf of the holder of this Note. (d) SUBROGATION. Subject to the prior payment in full in cash of all Senior Indebtedness, the holder of this Note shall be subrogated to the rights of the holders of Senior Indebtedness to receive payments or distributions of assets of the Company applicable to the Senior Indebtedness until all amounts owing on this Note shall be paid in full, and for the purpose of such subrogation no payments or distributions to the holders of the Senior Indebtedness by or on behalf of the Company or by or on behalf of the holder of this Note by virtue of this Section 11 which otherwise would have been made to the holder of this Note shall, as between the Company, its creditors other than the holders of Senior Indebtedness, and the holder of this Note, be deemed to be payment by the Company to or on account of the Senior Indebtedness, it being understood that the provisions of this Section 11 are and are intended solely for the purpose of defining the relative rights of the holder of this Note, on the one hand, and the holders of the Senior Indebtedness, on the other hand. (e) OBLIGATION OF THE COMPANY UNCONDITIONAL. Nothing contained in this Section 11 or in this Note is intended to or shall impair, as between the Company and the holder of this Note, the obligation of the Company, which is absolute and unconditional, to pay to the holder of this Note the principal of and interest on this Note as and when the same shall become due and payable in accordance with its terms, or is intended to or shall affect the relative rights of the holder of this Note and creditors of the Company other than the holders of the Senior Indebtedness, nor shall anything herein or therein prevent the holder of this Note from exercising all remedies otherwise permitted by applicable law upon an event of default under this Note, subject to the provisions of this Section 11 and Section 6 of this Note, including the rights of the holders of Senior Indebtedness in respect of assets of the Company received upon the exercise of any such remedy. Upon any distribution of assets of the Company referred to in this Section 11, the holder of this Note shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which such dissolution, winding up, liquidation or reorganization proceedings are pending, or a certificate of the liquidating trustee or agent or other person making any distribution to the holder of this Note, for the purpose of ascertaining the persons entitled to participate in such distribution, the holders of the Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Section 11. (f) SUBORDINATION RIGHTS NOT IMPAIRED BY ACTS OR OMISSIONS OF COMPANY OR HOLDERS OF SENIOR INDEBTEDNESS. No right of any present or future holders of any Senior Indebtedness to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act by any such holder, or by any noncompliance by the Company with the terms and provisions of this Note, regardless of any knowledge thereof which any such holder may have or be otherwise charged with. The holders of the Senior Indebtedness may, without in any way affecting the obligations of the holder of this Note with respect hereto, at any time or from time to time and in their absolute discretion, change the manner, place or terms of payment of, change or

extend the time of payment of, or renew, alter or increase, any Senior Indebtedness or amend, modify or supplement any agreement or instrument governing or evidencing such Senior Indebtedness or any other document referred to therein, or exercise or refrain from exercising any other of their rights under the Senior Indebtedness including, without limitation, the waiver of default thereunder and the release or impairment of any collateral securing such Senior Indebtedness, all without notice to or assent from the holder of the Note. (g) SENIOR INDEBTEDNESS. The term "SENIOR INDEBTEDNESS" shall mean all Obligations (i) of the Company under, or in respect of, the Credit Agreement (as amended, modified, supplemented, extended, restated, refinanced, replaced or refunded from time to time, the "CREDIT AGREEMENT"), dated as of July 16, 1999, among the Company and the other parties thereto, and (ii) of the Company under, or in respect of, any other indebtedness, whether outstanding on the date hereof or hereafter created, incurred or assumed, which the Company specifically designates in writing as "Senior Indebtedness" for purposes of this Note; provided, however, that no such other Senior Indebtedness described in this clause (ii) shall by its terms prohibit the repayment of the principal amount outstanding under this Note and accrued interest thereon at maturity unless an event of default has occurred and is continuing thereunder. As used herein, the term "OBLIGATION" shall mean any principal, interest, premium, penalties, fees, expenses, indemnities, reimbursements and other liabilities and obligations (including any guaranties of the foregoing liabilities and obligations) payable under the documentation governing any indebtedness (including interest after the commencement of any bankruptcy, insolvency, receivership or similar proceeding at the rate provided for in the respective issue of Senior Indebtedness, whether or not such interest is an allowed claim against the debtor in any such proceeding). (h) DESIGNATED SENIOR INDEBTEDNESS. The term Designated Senior Indebtedness means any Senior Indebtedness which, at the date of determination, has an aggregate principal amount outstanding of, or under which, at the date of determination, the holders thereof are committed to lend up to, at least $10 million. (i) OTHER DEFINED TERMS. The term "Senior Payment Default" shall mean any default in the payment of principal or (or premium, if any) or interest on, or other amount payable in respect of, any Senior Indebtedness when due that, by the terms of any instrument pursuant to which any Senior Indebtedness is outstanding, permits one or more holders of such Senior Indebtedness (or a trustee or agent or behalf of the holders thereof) to declare such Senior Indebtedness due and payable prior to the date on which it would otherwise become due and payable, other than a Senior Nonmonetary Default. The term "Senior Nonmonetary Default" shall mean the occurrence or existence of any event, circumstance, condition or state of facts that, by the terms of any instrument pursuant to which any Senior Indebtedness is outstanding, permits one or more holders of such Indebtedness (or a trustee or agent on behalf of the holders thereof) to declare such Senior Indebtedness due and payable prior to the date on which it would otherwise become due and payable, other than a Senior Payment Default. 12. BENEFITS OF THE AGREEMENT. The Investor and all transferees (to the extent permitted in the Agreement) shall be entitled to the rights and benefits granted to them in the Agreement.

13. REGISTRATION OF TRANSFER AND EXCHANGE GENERALLY. ----------------------------------------------- (a) REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE GENERALLY. The Company shall keep at its principal executive offices a register (the register maintained in such being herein sometimes collectively referred to as the "Note Register") in which the Company shall provide for the registration of Notes and of transfers and exchanges of Notes. Subject to the provisions of the Securityholders Agreement dated April __, 2000 regarding restrictions on transfer, upon surrender for registration of transfer of any Note at its principal executive office, the Company shall execute and deliver, in the name of the designated transferee or transferees, one or more new Notes in denominations of $1,000 or integral multiples thereof, of a like aggregate principal amount and bearing such restrictive legends as may be required by law. At the option of a holder, Notes may be exchanged for other Notes of any authorized denominations, of a like aggregate principal amount and bearing such restrictive legends as may be required by law upon surrender of the Notes to be exchanged at the Company's principal executive offices. Whenever any Notes are so surrendered for exchange, the Company shall execute and make available for delivery the Notes which the holder making the exchange is entitled to receive. All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits as the Notes surrendered upon such registration of transfer or exchange. Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company) be duly endorsed, or be accompanied by a written instrument of transfer, in form satisfactory to the Company, duly executed by the holder thereof or his attorney duly authorized in writing. No service charge shall be made for any registration of transfer or exchange of Notes. (b) MUTILATED, DESTROYED, LOST AND STOLEN NOTES. If any mutilated Note is surrendered to the Company, the Company shall execute and make available for delivery in exchange therefor a new Note of like tenor and principal amount and bearing a number not contemporaneously outstanding. If there shall be delivered to the Company (i) evidence to its satisfaction of the destruction, loss or theft of any Note and (ii) such security or indemnity as may be required by the Company to save itself harmless, then, in the absence of notice to the Company that such Note has been acquired by a protected purchaser, the Company shall execute and make available for delivery, in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and principal amount and bearing a number not contemporaneously outstanding.

In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Note, pay such Note, subject to the holders' conversion rights pursuant to Section 4 hereof. Every new Note issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be at any time enforceable by anyone. The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes. 14. GOVERNING LAW. This Note shall be governed by, and construed in accordance with, the laws of the State of New York.

THESE SECURITIES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR A VALID EXEMPTION THEREFROM UNDER SAID ACT OR LAWS. THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE ALSO SUBJECT TO CERTAIN RESTRICTIONS AS MORE PARTICULARLY DESCRIBED IN THAT CERTAIN SECURITYHOLDERS AGREEMENT DATED AS OF APRIL

12 17, 2000 (AS SUCH AGREEMENT MAY BE AMENDED, MODIFIED OR OTHERWISE SUPPLEMENTED FROM TIME TO TIME, THE "SECURITYHOLDERS AGREEMENT") AMONG THE ISSUER OF SUCH SECURITIES (THE "ISSUER") AND THE OTHER PARTIES THERETO.

The Legend will be removed by the Company by the delivery of substitute certificates without such Legend in the event the legend is no longer required for purposes of applicable securities laws. ARTICLE IV REGISTRATION RIGHTS SECTION IV.1 INCIDENTAL REGISTRATIONS. (a) If the Company at any time after the date hereof proposes to register Equity Securities under the Securities Act (other than a registration on Form S-4 or S-8, or any successor or other forms promulgated for similar purposes), whether or not for sale for its own account, in a manner which would permit registration of Registrable Securities for sale to the public under the Securities Act, it will, at each such time, give prompt written notice to all Holders of its intention to do so and of such Holders' rights under this Article IV. Upon the written request of any such Holder made within 15 days after the receipt of any such notice (which request shall specify the Registrable Securities intended to be disposed of by such Holder), the Company will use its reasonable best efforts to effect the registration under the Securities Act of all Registrable Securities which the Company has been so requested to register by the Holders thereof; PROVIDED, that (a) if, at any time after giving written notice of its intention to register any securities, the Company shall determine for any reason not to proceed with the proposed registration of the securities to be sold by it, the Company may, at its election, give written notice of such determination to each Holder and, thereupon, shall be relieved of its obligation to register any Registrable Securities in connection with such registration (but not from its obligation to pay the Registration Expenses in connection therewith), and (b) if such registration involves an underwritten offering, all Holders requesting to be included in the Company's registration must sell their Registrable Securities to the underwriters selected by the Company on the same terms and conditions as apply to the Company, with such differences, including any with respect to indemnification and liability insurance, as may be customary or appropriate in combined primary and secondary offerings. If a registration requested pursuant to this Section involves an underwritten public offering, any Holder requesting to be included in such registration may elect, in writing prior to the effective date of the registration statement filed in connection with such registration, not to register all or any part of such securities in connection with such registration. Nothing in this Section shall operate to limit the right of any Holder to request the registration of Common Stock issuable upon conversion, exchange or exercise of securities held by such Holder notwithstanding the fact that at the time of request such Holder does not hold the Common Stock underlying such securities. The registrations provided for in this Section 4.1 are in addition to, and not in lieu of, registrations made upon the request of any Investor Securityholder in accordance with Section 4.2.

13 (b) EXPENSES. The Company will pay all Registration Expenses in connection with each registration of Registrable Securities requested pursuant to this Section 4.1. (c) PRIORITY IN INCIDENTAL REGISTRATIONS. If a registration pursuant to this Section 4.1 involves an underwritten offering and the managing underwriter advises the Company in writing that, in its opinion, the number of Registrable Securities requested to be included in such registration would be likely to have an adverse effect on the price, timing or distribution of the securities to be offered in such offering as contemplated by the Company (other than the Registrable Securities), then the Company shall include in such registration (a) FIRST, 100% of the securities the Company proposes to sell, (b) SECOND, any Other Securities requested to be registered by any Other Holders exercising a demand registration right, and (c) THIRD, to the extent of the amount of Registrable Securities and Other Securities requested to be included in such registration which, in the opinion of such managing underwriter, can be sold without having the adverse effect referred to above, the amount of Registrable Securities and Other Securities which the Holders and the Other Holders have requested to be included in such registration, such amount to be allocated pro rata among all requesting Holders and the Other Holders on the basis of the relative amount of Registrable Securities and Other Securities then held by each such Holder and Other Holder (PROVIDED, that any such amount thereby allocated to any such Holder or Other Holder that exceeds such Holder's or Other Holder's request shall be reallocated among the remaining requesting Holders and Other Holders in like manner). SECTION IV.2 REGISTRATION ON REQUEST. (a) At any time after the date hereof, upon the written request of Silver Lake or any Transferee of Silver Lake; PROVIDED that no Transferee of Silver Lake or its Affiliates or of any Transferee shall be permitted to request a registration pursuant to this Section 4.2 unless the right to make such a request was transferred to such Transferee pursuant to Section 3.1(b) (the "DEMAND PARTY") requesting that the Company effect the registration under the Securities Act of all or part of such Demand Party's Registrable Securities and specifying the amount and intended method of disposition thereof, including without limitation, pursuant to a shelf registration statement utilizing Rule 415 under the Securities Act, the Company will promptly give written notice of such requested registration to all other Holders, and thereupon will, as expeditiously as possible, use its reasonable best efforts to effect the registration under the Securities Act of: (i) the Registrable Securities which the Company has been so requested to register by the Demand Party; and (ii) all other Registrable Securities which the Company has been requested to register by any other Holder thereof by written request given to the Company within 15 days after the giving of such written notice by the Company (which request shall specify the amount and intended method of disposition of such Registrable Securities), all to the extent necessary to permit the disposition (in accordance with the intended method thereof as aforesaid) of the Registrable Securities so to be registered; PROVIDED, that in no event shall the Company be required to effect more than three registrations pursuant to this Section 4.2 (which number shall be increased to four in the event any shares of Convertible Preferred Stock are issued); and PROVIDED, FURTHER, that, in the event the

14 Company shall not have postponed the filing of a registration statement required by this Section 4.2 pursuant to Section 4.2(g) hereof within a period of 360 days from the date of a demand notice under Section 4.2(a), the Company shall not be obligated to file a registration statement relating to any registration request under this Section 4.2 (other than a registration statement on Form S-3 or any successor or similar short-form registration statement) within a period of 90 days after the effective date of any other registration statement relating to any registration request under this Section 4.2 or to any registration effected under Section 4.1, in either case which was not effected on Form S-3 (or any successor or similar short-form registration statement). Nothing in this Section 4.2 shall operate to limit the right of any Holder to request the registration of Common Stock issuable upon conversion of the Notes or the Convertible Preferred Stock or the conversion, exchange or exercise of any other securities held by such Holder notwithstanding the fact that at the time of request such Holder does not hold the Common Stock underlying such securities. (b) REGISTRATION STATEMENT FORM. The Company shall select the registration statement form for any registration pursuant to this Section 4.2; PROVIDED, that if any registration requested pursuant to this Section 4.2 which is proposed by the Company to be effected by the filing of a registration statement on Form S-3 (or any successor or similar short-form registration statement) shall be in connection with an underwritten public offering, and if the managing underwriter shall advise the Company in writing that, in its opinion, the use of another form of registration statement is of material importance to the success of such proposed offering, then such registration shall be effected on such other form. (c) EXPENSES. The Company will pay all Registration Expenses in connection with registrations of each class or series of Registrable Securities pursuant to this Section 4.2. (d) EFFECTIVE REGISTRATION STATEMENT. A registration requested pursuant to this Section 4.2 will not be deemed to have been effected unless it has become effective and all of the Registrable Securities registered thereunder have been sold. (e) SELECTION OF UNDERWRITERS. If a requested registration pursuant to this Section 4.2 involves an underwritten offering, the investment banker(s), underwriter(s) and manager(s) for such registration shall be selected by the Holders of a majority of the Registrable Securities which the Company has been requested to register; PROVIDED, HOWEVER, that such investment banker(s), underwriter(s) and manager(s) shall be reasonably satisfactory to the Company. (f) PRIORITY IN REQUESTED REGISTRATIONS. If a requested registration pursuant to this Section 4.2 involves an underwritten offering and the managing underwriter advises the Company in writing that, in its opinion, the number of securities to be included in such registration (including securities of the Company which are not Registrable Securities) would be likely to have an adverse effect on the price, timing or distribution of the securities to be offered in such offering as contemplated by the Holders (an "ADVERSE EFFECT"), then the Company shall include in such registration (a) FIRST, 100% of the Registrable Securities requested to be included in such registration by the Demand Party and all other Holders of Registrable Securities pursuant to this

15 Section 4.2 (to the extent that the managing underwriter believes that all such Registrable Securities can be sold in such offering without having an Adverse Effect; PROVIDED, that if they cannot and the Demand Party does not exercise its right set forth in the second succeeding sentence of this clause (f), such lesser number of Registrable Securities as specified by the Demand Party) and (B) SECOND, to the extent the managing underwriter believes additional securities can be sold in the offering without having an Adverse Effect, the amount of Other Securities requested to be included by Other Holders in such registration, allocated pro rata among all requesting Other Holders on the basis of the relative amount of all Other Securities then held by each such Other Holder (PROVIDED, that any such amount thereby allocated to any such Other Holder that exceeds such Other Holder's request shall be reallocated among the remaining requesting Other Holders in like manner). In the event that the number of Registrable Securities and Other Securities to be included in such registration is less than the number which, in the opinion of the managing underwriter, can be sold without having an Adverse Effect, the Company may include in such registration the securities the Company proposes to sell up to the number of securities that, in the opinion of such managing underwriter, can be sold without having an Adverse Effect. If the managing underwriter of any underwritten offering shall advise the Holders participating in a registration pursuant to this Section 4.2 that the Registrable Securities covered by the registration statement cannot be sold in such offering within a price range acceptable to the Demand Party, then the Demand Party shall have the right to notify the Company that it has determined that the registration statement be abandoned or withdrawn, in which event the Company shall abandon or withdraw such registration statement. (g) POSTPONEMENTS IN REQUESTED REGISTRATIONS. Notwithstanding Section 4.2(f), (i) if the Board determines, in its good faith judgment, that the registration and offering otherwise required by this Section 4.2 would have an adverse effect on a then contemplated public offering of the Company's Equity Securities, the Company may postpone the filing (but not the preparation) of a registration statement required by this Section 4.2, during the period starting with the 30th day immediately preceding the date of the anticipated filing of, and ending on a date 60 days following the effective date of, the registration statement relating to such other public offering and (ii) if the Company shall at any time furnish to the Holders a certificate signed by its chairman of the board, chief executive officer, president or any other of its authorized officers stating that the Company or any Subsidiary of the Company has pending or in process a material transaction, the disclosure of which would, in the good faith judgment of the Board, after consultation with its outside securities counsel, materially and adversely affect the Company or such Subsidiary, the Company may postpone the filing (but not the preparation) of a registration statement required by this Section 4.2 for up to 90 days; PROVIDED, that, the Company shall at all times in good faith use its reasonable best efforts to cause any registration statement required by this Section 4.2 to be filed as soon as possible thereafter and; PROVIDED, FURTHER, that, the Company shall not be permitted to postpone registration pursuant to this Section 4.2(g) more than once in any 360-day period. The Company shall promptly give the Holders requesting registration thereof pursuant to this Section 4.2 written notice of any postponement made in accordance with the preceding sentence. If the Company gives the Holders such a notice, the Holders shall have the right, within 15 days after receipt thereof, to withdraw their request in which case, such request will not be counted for purposes of this Section 4.2.

16 (h) ADDITIONAL RIGHTS. If the Company at any time grants to any other holders of capital stock any rights to request the Company to effect the registration under the Securities Act of any such shares of capital stock on terms more favorable to such holders than the terms set forth in this Article IV, the terms of this Article IV shall be deemed amended or supplemented to the extent necessary to provide the Holders such more favorable rights and benefits. The Company shall provide the Holders prior written notice of any such deemed amendment or supplement to the terms of this Article IV. SECTION IV.3 REGISTRATION PROCEDURES. If and whenever the Company is required to use its reasonable best efforts to effect or cause the registration of any Registrable Securities under the Securities Act as provided in this Agreement, the Company will promptly: (a) prepare and, in any event within 45 days after the end of the period within which a request for registration may be given to the Company, file with the SEC a registration statement with respect to such Registrable Securities and use its reasonable best efforts to cause such registration statement to become effective within 90 days of the initial filing; (b) prepare and file with the SEC such amendments and supplements to such registration statement (including Exchange Act documents incorporated by reference into the registration statement) and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for a period not in excess of 180 days (or such longer period as may be requested by the Holders in the event of a shelf registration statement) and to comply with the provisions of the Securities Act and the Exchange Act with respect to the disposition of all securities covered by such registration statement during such period in accordance with the intended methods of disposition by the seller or sellers thereof set forth in such registration statement; PROVIDED, that before filing a registration statement or prospectus, or any amendments or supplements thereto in accordance with Sections 4.3(a) or (b), the Company will furnish to counsel selected pursuant to Section 4.8 hereof copies of all documents proposed to be filed, which documents will be subject to the review of such counsel; (c) furnish to each seller of such Registrable Securities such number of copies of such registration statement and of each amendment and supplement thereto (in each case including all exhibits filed therewith, including any documents incorporated by reference), such number of copies of the prospectus included in such registration statement (including each preliminary prospectus and summary prospectus), in conformity with the requirements of the Securities Act, and such other documents as such seller may reasonably request in order to facilitate the disposition of the Registrable Securities by such seller; (d) use its reasonable best efforts to register or qualify such Registrable Securities covered by such registration in such jurisdictions as each seller shall reasonably request, and do any and all other acts and things which may be reasonably necessary or advisable to enable such seller to consummate the disposition in such jurisdictions of the Registrable Securities owned by such seller, except that the Company shall not for any such purpose

17 be required to qualify generally to do business as a foreign corporation in any jurisdiction where, but for the requirements of this subsection (d), it would not be obligated to be so qualified, to subject itself to taxation in any such jurisdiction or to consent to general service of process in any such jurisdiction; (e) use its reasonable best efforts to cause such Registrable Securities covered by such registration statement to be registered with or approved by such other governmental authorities as may be necessary to enable the seller or sellers thereof to consummate the disposition of such Registrable Securities; (f) notify each seller of any such Registrable Securities covered by such registration statement, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the Company's becoming aware that the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing, and at the request of any such seller, prepare and furnish to such seller a reasonable number of copies of an amended or supplemental prospectus as may be necessary so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; (g) otherwise use its best efforts to comply with all applicable rules and regulations of the SEC, and make available to its security holders, as soon as reasonably practicable (but not more than 18 months) after the effective date of the registration statement, an earnings statement which shall satisfy the provisions of Section 11(a) of the Securities Act; (h) (i) use its reasonable best efforts to list such Registrable Securities on any securities exchange on which the Common Stock is then listed if such Registrable Securities are not already so listed and if such listing is then permitted under the rules of such exchange; and (ii) use its best efforts to provide a transfer agent and registrar for such Registrable Securities covered by such registration statement not later than the effective date of such registration statement; (i) enter into such customary agreements (including an underwriting agreement in customary form), which may include indemnification provisions in favor of underwriters and other Persons in addition to, or in substitution for the provisions of Section 4.6 hereof, and take such other actions as sellers of a majority of shares of such Registrable Securities or the underwriters, if any, reasonably requested in order to expedite or facilitate the disposition of such Registrable Securities; (j) obtain a "cold comfort" letter or letters from the Company's independent public accounts in customary form and covering matters of the type customarily covered by "cold

18 comfort" letters as the seller or sellers of a majority of shares of such Registrable Securities shall reasonably request; (k) make available for inspection by any seller of such Registrable Securities covered by such registration statement, by any underwriter participating in any disposition to be effected pursuant to such registration statement and by any attorney, accountant or other agent retained by any such seller or any such underwriter, all pertinent financial and other records, pertinent corporate documents and properties of the Company, and cause all of the Company's officers, directors and employees to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such registration statement; (l) notify counsel (selected pursuant to Section 4.8 hereof) for the Holders of Registrable Securities included in such registration statement and the managing underwriter or agent, immediately, and confirm the notice in writing (i) when the registration statement, or any post-effective amendment to the registration statement, shall have become effective, or any supplement to the prospectus or any amendment to the prospectus shall have been filed, (ii) of the receipt of any comments from the SEC, (iii) of any request of the SEC to amend the registration statement or amend or supplement the prospectus or for additional information, and (iv) of the issuance by the SEC of any stop order suspending the effectiveness of the registration statement or of any order preventing or suspending the use of any preliminary prospectus, or of the suspension of the qualification of the registration statement for offering or sale in any jurisdiction, or of the institution or threatening of any proceedings for any of such purposes; (m) make reasonable best efforts to prevent the issuance of any stop order suspending the effectiveness of the registration statement or of any order preventing or suspending the use of any preliminary prospectus and, if any such order is issued, to obtain the withdrawal of any such order as soon as practicable; (n) if requested by the managing underwriter or agent or any Holder of Registrable Securities covered by the registration statement, promptly incorporate in a prospectus supplement or post-effective amendment such information as the managing underwriter or agent or such Holder reasonably requests to be included therein, including, with respect to the number of Registrable Securities being sold by such Holder to such underwriter or agent, the purchase price being paid therefor by such underwriter or agent and with respect to any other terms of the underwritten offering of the Registrable Securities to be sold in such offering; and make all required filings of such prospectus supplement or post-effective amendment as soon as practicable after being notified of the matters incorporated in such prospectus supplement or post-effective amendment; (o) cooperate with the Holders of Registrable Securities covered by the registration statement and the managing underwriter or agent, if any, to facilitate the timely preparation and delivery of certificates (not bearing any restrictive legends) representing securities to be sold under the registration statement, and enable such

SECTION IV.4 INFORMATION SUPPLIED. The Company may require each seller of Registrable Securities as to which any registration is being effected to furnish the Company with such information regarding such seller and pertinent to the disclosure requirements relating to the registration and the distribution of such securities as the Company may from time to time reasonably request. SECTION IV.5 RESTRICTIONS ON DISPOSITION. Each Holder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 4.3(f), such Holder will forthwith discontinue disposition of Registrable Securities pursuant to the registration statement covering such Registrable Securities until such Holder's receipt of the copies of the supplemented or amended prospectus contemplated by Section 4.3(f), and, if so directed by the Company, such Holder will deliver to the Company (at the Company's expense) all copies, other than permanent file copies then in such Holder's possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice. In the event the Company shall give any such notice, the period mentioned in Section 4.3(b) shall be extended by the number of days during the period from and including the date of the giving of such notice pursuant to Section 4.3(f) and to and including the date when each seller of Registrable Securities covered by such registration statement shall have received the copies of the supplemented or amended prospectus contemplated by Section 4.3(f). SECTION IV.6 INDEMNIFICATION. (a) In the event of any registration of any securities of the Company under the Securities Act pursuant to Section 4.1 or 4.2, the Company shall, and it hereby does, indemnify and hold harmless, to the extent permitted by law, the seller of

20 any Registrable Securities covered by such registration statement, each Affiliate of such seller and their respective directors, officers, members or general and limited partners (and any director, officer, and controlling Person of any of the foregoing), each Person who participates as an underwriter in the offering or sale of such securities and each other Person, if any, who controls such seller or any such underwriter within the meaning of the Securities Act (collectively, the "INDEMNIFIED PARTIES"), against any and all losses, claims, damages or liabilities, joint or several, actions or proceedings (whether commenced or threatened) in respect thereof ("CLAIMS") and expenses (including reasonable attorney's fees and reasonable expenses of investigation) to which such Indemnified Party may become subject under the Securities Act, common law or otherwise, insofar as such Claims or expenses arise out of, relate to or are based upon (a) any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such securities were registered under the Securities Act, any preliminary, final or summary prospectus contained therein, or any amendment or supplement thereto, or (b) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading; PROVIDED, that the Company shall not be liable to any Indemnified Party in any such case to the extent that any such Claim or expense arises out of, relates to or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement or amendment or supplement thereto or in any such preliminary, final or summary prospectus in reliance upon and in conformity with written information furnished to the Company by or behalf of such seller specifically stating that it is for use in the preparation thereof. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of any Indemnified Party and shall survive the transfer of securities by any seller. (b) The Company may require, as a condition to including any Registrable Securities in any registration statement filed in accordance with Section 4.2 or 4.3 herein, that the Company shall have received an undertaking reasonably satisfactory to it from the prospective seller of such Registrable Securities or any underwriter to indemnify and hold harmless (in the same manner and to the same extent as set forth in Section 4.6(a)) the Company and all other prospective sellers or any underwriter, as the case may be, with respect to any untrue statement or alleged untrue statement in or omission or alleged omission from such registration statement, any preliminary, final or summary prospectus contained therein, or any amendment or supplement thereto, if such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by or on behalf of such seller or underwriter specifically stating that it is for use in the preparation of such registration statement, preliminary, final or summary prospectus or amendment or supplement, or a document incorporated by reference into any of the foregoing. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Company or any of the prospective sellers, or any of their respective Affiliates, directors, officers or controlling Persons and shall survive the transfer of securities by any seller. In no event shall the liability of any selling Holder of Registrable Securities hereunder be greater in amount than the dollar amount of the proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such indemnification obligation.

21 (c) Promptly after receipt by an indemnified party hereunder of written notice of the commencement of any action or proceeding with respect to which a claim for indemnification may be made pursuant to this Section 4.6, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party, give written notice to the latter of the commencement of such action or proceeding; PROVIDED, that the failure of the indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under Section 4.6, except to the extent that the indemnifying party is materially prejudiced by such failure to give notice. In case any such action or proceeding is brought against an indemnified party, unless in such indemnified party's reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist in respect of such action or proceeding (in which case the indemnified party shall have the right to assume or continue its own defense and the indemnifying party shall be liable for any reasonable expenses therefor, but in no event will bear the expenses for more than one firm of counsel for all indemnified parties in each jurisdiction who shall be approved by the majority of the participating Holders in the registration in respect of which such indemnification is sought), the indemnifying party will be entitled to participate in and to assume the defense thereof (at its expense), jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof other than reasonable costs of investigation and shall have no liability for any settlement made by the indemnified party without the consent of the indemnifying party, such consent not to be unreasonably withheld. No indemnifying party will settle any action or proceeding or consent to the entry of any judgment without the prior written consent of the indemnified party, unless such settlement or judgment (i) includes as an unconditional term thereof the giving by the claimant or plaintiff of a release to such indemnified party from all liability in respect of such action or proceeding and (ii) does not involve the imposition of equitable remedies or the imposition of any obligations on such indemnified party and does not otherwise adversely affect such indemnified party, other than as a result of the imposition of financial obligations for which such indemnified party will be indemnified hereunder. (d) (i) If the indemnification provided for in this Section 4.6 from the indemnifying party is unavailable to an indemnified party hereunder in respect of any Claim or expenses referred to herein, then the indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Claim or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and indemnified party in connection with the actions which resulted in such Claim or expenses, as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such indemnifying party or indemnified party, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party under this Section 4.6(d) as a result of the Claim and expenses referred to above shall be

22 deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with any action or proceeding. (ii) The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.6(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in Section 4.6(d)(i). 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. (e) Indemnification similar to that specified in this Section 4.6 (with appropriate modifications) shall be given by the Company and each seller of Registrable Securities with respect to any required registration or other qualification of securities under any Law or with any governmental authority other than as required by the Securities Act. (f) The obligations of the parties under this Section 4.6 shall be in addition to any liability which any party may otherwise have to any other party. SECTION IV.7 REQUIRED REPORTS. The Company covenants that it will file the reports required to be filed by it under the Securities Act and the Exchange Act (or, if the Company is not required to file such reports, it will, upon the request of any Holder, make publicly available such information), and it will take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell shares of Registrable Securities and Notes without registration under the Securities Act within the limitation of the exemptions provided by (a) Rule 144 under the Securities Act, as such Rule may be amended from time to time, or (b) any similar rule or regulation hereafter adopted by the SEC. Upon the request of any Holder, the Company will deliver to such Holder a written statement as to whether it has complied with such requirements. SECTION IV.8 SELECTION OF COUNSEL. In connection with any registration of Registrable Securities pursuant to Sections 4.1 and 4.2 hereof, the Holders of a majority of the Registrable Securities covered by any such registration may select one counsel to represent all Holders of Registrable Securities covered by such registration; PROVIDED, HOWEVER, that in the event that the counsel selected as provided above is also acting as counsel to the Company in connection with such registration, the remaining Holders shall be entitled to select one additional counsel to represent all such remaining Holders. SECTION IV.9 HOLDBACK AGREEMENT. If any registration hereunder shall be in connection with an underwritten public offering, each Holder agrees not to effect any public sale or distribution, including any sale pursuant to Rule 144 under the Securities Act, of any Equity Securities of the Company (in each case, other than as part of such underwritten public offering), within 10 days before, or subject to Section 4.2(g) in the case of a requested registration that has been postponed pursuant to clause (i) thereof, 180 days (or such lesser period as the managing underwriters may require or permit) after, the effective date of such registration (except as part of such registration), and the Company hereby also agrees to use its reasonable best efforts to

23 have each other holder of any Equity Security of the Company purchased from the Company (at any time other than in a public offering) to so agree. SECTION IV.10 NO INCONSISTENT AGREEMENTS. The Company represents and warrants that it is not a party to, will not enter into, or cause or permit any of its Subsidiaries to enter into, any agreement which conflicts with or limits or prohibits the exercise of the rights granted to the Holders of Registrable Securities in this Article IV. ARTICLE V EQUITY PURCHASE RIGHTS SECTION V.1 SUBSIDIARY PURCHASE RIGHTS. (a) The Company hereby grants to the Purchasers, as defined in the Securities Purchase Agreement (such Purchasers referred to in this Section 5.1 as the "PURCHASERS"), an option (the "TECHREPUBLIC OPTION") to purchase up to 5.00% (as may be allocated among the Purchasers in their discretion) of the fully diluted capital stock of TechRepublic, Inc. ("TECHREPUBLIC") (after giving effect to all the transactions contemplated by the Agreement and Plan of Reorganization dated March 21, 2000 between the Company, TechRepublic and the other parties thereto (the "TECHREPUBLIC Agreement")) pursuant to the general terms and conditions applicable to the Company set forth in the TechRepublic Agreement and at a price which values TechRepublic at the lesser of (a) the value assigned to TechRepublic in connection with the Company's purchase, or (b) $90.0 million. In the event TechRepublic issues to the Company any options, warrants, convertible securities or capital stock subsequent to the consummation of the transactions contemplated by the TechRepublic Agreement, the Purchasers shall receive options to purchase additional shares of TechRepublic capital stock in an amount sufficient to permit it to maintain its 5% stake of TechRepublic on a fully diluted basis (giving effect to all options, warrants or convertible securities issued to the Company on an as converted basis) at an exercise price equal to (i) the per share price received by TechRepublic in connection with such issuance or (ii) the per share exercise price or conversion price of the options, warrants or convertible securities issued, as the case may be. Prior to any contribution of assets (other than cash) by the Company to TechRepublic, the Company shall notify the Purchasers and the Company and the Purchasers shall negotiate in good faith to agree upon the value to the assets to be contributed. The Company and the Purchasers will use reasonable best efforts to enable the Company to include TechRepublic in its consolidated group for federal income tax purposes. (b) In the event that a Purchaser elects to purchase shares of the capital stock of TechRepublic during the term of this Article V, such Purchaser shall give the Company written notice of such election, which notice shall specify the number of shares of capital stock such Purchaser is electing to purchase, provided that the total number of shares of capital stock purchased by all Purchasers shall not exceed 5.00% of the fully diluted capital stock of TechRepublic (after giving effect to all of the transactions contemplated by the TechRepublic Agreement).

24 (c) The Company hereby grants to the Purchasers the right (the "SPIN Right"; together with the TechRepublic Option, the "OPTION") to purchase up to 5.00% (as may be allocated among the Purchasers in their discretion) of the fully diluted common stock of any Subsidiary of the Company whose shares of common stock are (i) distributed to stockholders of the Company ("SPUN-OFF") or (ii) sold by the Company in a public offering ("SPUN-OUT") at a per share price equal to (x) 80.0% of the initial public offering price in the case of a spun-out Subsidiary and (y) 80.0% of the first day's closing price in the case of a spun-off subsidiary. (d) In the event that the Company effects either a spun-off or spun-out subsidiary transaction during the term of this Article V, the Company shall give each Purchaser written notice of such transaction at least 30 business days prior to the consummation of the spin-off or spin-out, as the case may be. If timely notice has been received, on or prior to ten business days prior to the consummation of the spin-off or spin-out, as the as may be, each Purchaser shall notify the Company in writing of the number of shares of common stock, if any, such Purchaser is electing to purchase in such transaction (each a "Response"), provided that the total number of shares of common stock purchased by all Purchasers in each such transaction shall not exceed 5.00% of the fully diluted common stock of the subject subsidiary. An election by a Purchaser to purchase shares of common stock shall be deemed to be an irrevocable commitment from such Purchaser to purchase the number of shares of common stock specified in such Purchaser's Response.

SECTION VII.8 DELAYS OR OMISSIONS. It is agreed that no delay or omission to exercise any right, power or remedy accruing to any party, upon any breach, default or noncompliance by another party under this Agreement, shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence therein, or of or in any similar breach, default or noncompliance thereafter

28 occurring. It is further agreed that any waiver, permit, consent or approval of any kind or character on the part of any party hereto of any breach, default or noncompliance under this Agreement or any waiver on such party's part of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing.

SECTION VII.11 EFFECTIVE DATE. This Agreement shall become effective immediately upon the Closing. SECTION VII.12 ENFORCEMENT.
