        2.    Registration Under the 1933 Act.

3



    The Shelf Registration shall be on Form S-3 under the 1933 Act or another appropriate form permitting registration of such Registrable Securities for resale by the Holders in the manner or manners reasonably designated by them (including, without limitation, one or more underwritten offerings). The Company shall use its reasonable best efforts to cause the Registration Statement to be declared effective by the SEC as promptly as practicable, but no later than the Effectiveness Target Date, and to keep the Registration Statement continuously effective, supplemented and amended, as required in order to permit the Prospectus forming a part thereof to be useable by the Holders until the earliest of (i) two years after the last date of issuance of the Notes, (ii) the date when the Holders are able to sell all of their Securities immediately without restriction pursuant to the volume limitation provisions of Rule 144 under the 1933 Act or otherwise, or (iii) all of the Registrable Securities covered by the Registration Statement have been sold pursuant to the Registration Statement (the "Effectiveness Period").

            (b)   Notwithstanding any other provisions hereof, the Company shall use its reasonable best efforts to ensure that (i) any Registration Statement and any amendment thereto and any Prospectus forming a part thereof and any supplements thereto complies in all material respects with the 1933 Act, (ii) any Registration Statement and any amendment thereto does not, when it becomes effective, contain 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 and (iii) any Prospectus forming a part of any Registration Statement and any amendment or supplement to such Prospectus, does not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

            (c)   The Company shall not permit any securities other than Registrable Securities to be included in the Registration Statement. The Company further agrees, if necessary, to supplement or amend the Registration Statement, as required by Section 3(b) below.

            (d)   Notwithstanding any other provision hereof, no Holder of Registrable Securities may include any of its Registrable Securities in the Registration Statement pursuant to this Agreement unless the Holder furnishes to the Company a completed questionnaire in the form attached as Annex A to the Offering Memorandum (the "Questionnaire") and such other information in writing as the Company may reasonably request in writing for use in connection with the Registration Statement or Prospectus included therein and in any application to be filed with or under state securities laws. Before the effectiveness of the Registration Statement and no later than the 20th business day after receipt of the notice by a Holder from the Company of the filing of the Registration Statement (which notice shall include the Questionnaire and any other reasonable information requested by the Company for use in connection with the Registration Statement), each such Holder of Registrable Securities must furnish the completed Questionnaire and such other information, if any, to the Company in writing and the Company will include the information from the completed Questionnaire and such other information, if any, in the Registration Statement in a manner so that upon effectiveness the Holders will be permitted to deliver the Prospectus to purchasers of the Holder's Securities. From and after the date that the Registration Statement is first declared effective, upon receipt of a completed Questionnaire and such other information, if any, the Company will, as promptly as practicable but in any event within 5 business days of receipt, file any amendments or supplements to the Registration Statement necessary for the relevant Holders to be named as selling securityholders in the Prospectus contained therein to be permitted to deliver the Prospectus to purchasers of the Holder's Securities (subject to the Company's right to suspend the Registration Statement as described in Sections 3(e)(iii), 3(e)(v) and 3(e)(vi) below). Holders that do not deliver a completed written Questionnaire and such other information, if any, in a timely manner, as provided for in this Section 2.1(d), will not be named as selling securityholders in the Prospectus. Each Holder as

4



    to which the Registration Statement is being effected agrees to furnish promptly to the Company all information required to be disclosed in order to make information previously furnished to the Company by the Holder not materially misleading.

            2.2    Expenses.    

            The Company shall pay all Registration Expenses in connection with the Shelf Registration and any Registration Statement. Each Holder shall pay all fees and disbursements of its counsel (other than as set forth in the preceding sentence or in the definition of Registration Expenses) and all underwriting discounts and commissions and transfer taxes, if any, relating to the sale or disposition of such Holder's Registrable Securities pursuant to the Registration Statement.

            2.3    Effectiveness.    

            The Registration Statement shall not be deemed to have become effective unless it has been declared effective by the SEC; provided, however, that if, after it has been declared effective, the offering of Registrable Securities pursuant to the Registration Statement is interfered with by any stop order, injunction or other order or requirement of the SEC or any other governmental agency or court, such Registration Statement shall be deemed not to have been effective during the period of such interference, until the offering of Registrable Securities pursuant to such Registration Statement may legally resume.

            2.4    Liquidated Damages.    

            The Company and the Initial Purchasers agree that the Holders of Registrable Securities will suffer damages if the Company fails to fulfill its obligations under Section 2.1 hereof and that it would not be feasible to ascertain the extent of such damages with precision. Accordingly, the Company agrees to pay liquidated damages on the Registrable Securities ("Liquidated Damages") under the circumstances and to the extent as set forth below. In the event that (a) the Registration Statement has not been filed with the SEC on or prior to the Filing Date, (b) the Registration Statement is not declared effective by the SEC on or prior to the Effectiveness Target Date, (c) the Registration Statement has been declared effective by the SEC and such Registration Statement ceases to be effective or usable at any time during the Effectiveness Period for any reason without being succeeded within five business days by a post-effective amendment to such Registration Statement or a report filed with the SEC pursuant to the 1934 Act that cures such failure or (d) the Company suspends the use of any Prospectus related to the Registration Statement for a period exceeding forty-five (45) days in any consecutive three-month period or exceeding an aggregate of ninety (90) days in any consecutive twelve-month period (each such event referred to in clauses (a) through (d) above, a "Registration Default"), then the interest rate borne by the Notes shall be increased as Liquidated Damages (x) by one-quarter of one percent (0.25%) per annum upon the occurrence of such Registration Default up to and including the ninetieth (90th) day following such Registration Default and (y) by one half of one percent (0.50%) from and after the ninety-first (91st) day following the occurrence of such Registration Default, provided that the aggregate increase in such interest rate will in no event exceed one half of one percent (0.50%) per annum. Upon the cure of such Registration Default, the accrual of Liquidated Damages will cease and the interest rate will revert to the original rate so long as no other Registration Default shall have occurred and shall be continuing at such time; provided, however, that, if after any such reduction in interest rate, one or more Registration Defaults shall again occur, the interest rate shall again be increased pursuant to the foregoing provisions. A Registration Default under clause (a) above shall be cured on the date that the Shelf Registration is filed with the SEC; a Registration Default under clause (b) above shall be cured on the date that the Shelf Registration is declared effective by the SEC; a Registration Default under clause (c) above shall be cured on the date the Shelf Registration is declared effective or useable; and a Registration Default under clause (d) above shall be cured on the date the Prospectus is

5



    declared useable by the Company. In the event of a Registration Default, the Company shall pay Liquidated Damages to (x) the holders of Notes and (y) the holders of Common Stock issued upon conversion of Notes in proportion to the principal amount of such Notes converted.

            The Company shall notify the Trustee within three business days after each and every date on which a Registration Default occurs (an "Event Date"). Liquidated Damages shall be paid by the Company to the Holders of Notes by depositing with the Trustee, in trust, for the benefit of the Holders of Notes, on or before the applicable semiannual interest payment date, immediately available funds in sums sufficient to pay the Liquidated Damages then due. Such Liquidated Damages due shall be payable on each interest payment date to the record Holder of Securities entitled to receive the interest payment to be paid on such date as set forth in the Indenture. Liquidated Damages in respect of Common Stock issued upon conversion of Notes shall be payable by the Company to the holders of Common Stock issued upon conversion of such Notes concurrently with the payment of Liquidated Damages to the holders of Notes. Each obligation to pay Liquidated Damages shall be deemed to accrue from and including the day following the applicable Event Date.

        3.    Registration Procedures.

    is contained in a Registration Statement declared effective by the SEC, or any amendment or supplement thereto by each of the Holders and underwriters of Registrable Securities in connection with the offering and sale of the Registrable Securities covered by any Prospectus that is contained in a Registration Statement declared effective by the SEC or any amendment or supplement thereto;

            (d)   use its reasonable best efforts to register or qualify (or establish an exemption from such registration or qualification for) the Registrable Securities under all applicable state securities or "blue sky" laws of such jurisdictions as any Holder of Registrable Securities covered by a Registration Statement and each underwriter of an underwritten offering of Registrable Securities shall reasonably request, to cooperate with the Holders and the underwriters of any Registrable Securities in connection with any filings required to be made with the NASD, to keep each such registration or qualification effective during the period such Registration Statement is required to be effective, and do any and all other acts and things which may be reasonably necessary or advisable to enable such Holder and underwriter to consummate the disposition in each such jurisdiction of such Registrable Securities owned by such Holder; provided, however, that the Company shall not be required to (i) qualify as a foreign corporation or as a dealer in securities in any jurisdiction where it would not otherwise be required to qualify but for this Section 3(d) or (ii) take any action which would subject it to general service of process or taxation in any such jurisdiction if it is not then so subject;

            (e)   notify each Holder of Registrable Securities as promptly as reasonably practicable and, if requested by such Holder, confirm such advice in writing as promptly as reasonably practicable (i) when a Registration Statement has become effective and when any post-effective amendments and supplements thereto become effective, (ii) of any request by the SEC or any state securities authority for post-effective amendments or supplements to a Registration Statement or Prospectus or for additional information after a Registration Statement has become effective, (iii) of the issuance by the SEC or any state securities authority of any stop order suspending the effectiveness of a Registration Statement or the initiation of any proceedings for that purpose, (iv) if between the effective date of a Registration Statement and the closing of any sale of Registrable Securities covered thereby, the representations and warranties of the Company contained in any underwriting agreement, securities sales agreement or other similar agreement, if any, relating to such offering cease to be true and correct in all material respects, (v) of the happening of any event or the discovery of any facts during the period a Registration Statement is effective which makes any statement made in such Registration Statement or the related Prospectus untrue in any material respect or which constitutes an omission to state a material fact in such Registration Statement or Prospectus or which requires the making of any changes in such Registration Statement or Prospectus in order to make the statements therein not misleading, (vi) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose and (vii) of any reasonable determination by the Company that a post-effective amendment to a Registration Statement would be appropriate;

The Company agrees to notify each Holder to suspend use of the Prospectus as promptly as practicable after the occurrence of such an event, and each Holder hereby agrees to suspend use of the Prospectus until the Company has amended or supplemented the Prospectus to correct such misstatement or omission. At such time as such public disclosure is otherwise made or the Company determines that such disclosure is not necessary, in each case to correct any misstatement of a material fact or to include any omitted material fact, the Company agrees promptly to notify each Holder of such determination and to furnish each Holder such number of copies of the Prospectus, as amended or supplemented, as such Holder may reasonably request;

            (i)    a reasonable time prior to the filing of any Registration Statement, any Prospectus, any amendment to a Registration Statement or amendment or supplement to a Prospectus or a Prospectus after the initial filing of a Registration Statement, provide copies of such document to the Initial Purchasers on behalf of such Holders if requested by the Initial Purchasers; and make representatives of the Company as shall be reasonably requested by the Holders of Registrable Securities, or the Initial Purchasers on behalf of such Holders, available for discussion of such document;

              (iv)  if an underwriting agreement is entered into, cause the same to set forth indemnification and contribution provisions and procedures substantially equivalent to the indemnification and contribution provisions and procedures set forth in Section 4 hereof with respect to the underwriters and all other parties to be indemnified pursuant to Section 4 hereof or, at the request of any underwriters, in the form customarily provided to such underwriters in similar types of transactions; and

               (v)  deliver such other documents and certificates as may be reasonably requested and as are customarily delivered in similar offerings to the Holders of a majority in principal amount of the Registrable Securities being sold and the managing underwriters, if any.

            (n)   a reasonable time prior to filing any Registration Statement, any Prospectus forming a part thereof, any amendment to such Registration Statement or amendment or supplement to such Prospectus (other than supplements that do nothing more than name one or more Holders and provide information with respect thereto), provide copies of such document upon request to the Initial Purchasers, to the underwriter or underwriters of an underwritten offering of Registrable Securities, if any, and, to counsel for the Initial Purchasers or underwriters, and make such changes in any such document prior to the filing thereof as the Initial Purchasers or the underwriter or underwriters, or any of their respective counsel may reasonably request in writing within five business days after the delivery of such copies by the Company; cause the representatives of the Company to be available for discussion of such documents during normal business hours as shall be reasonably requested by the Initial Purchasers on behalf of the Holders or any underwriter or any of their respective counsel; and shall not at any time make any filing of any such document of which the Initial Purchasers on behalf of the Holders, their counsel or any underwriter or their counsel shall not have previously been advised and furnished a copy or to which the Majority Holders, the Initial Purchasers on behalf of the Holders, their counsel or any underwriter or their counsel shall reasonably object within a reasonable time period;

            (o)   use its reasonable best efforts to cause all Registrable Securities to be listed on any securities exchange or inter-dealer quotation system such as NASDAQ on which similar debt or equity securities issued by the Company are then listed, if any;

            (p)   use its commercially reasonable efforts to cause the Registrable Securities to be rated with the appropriate rating agencies, if reasonably requested by the Majority Holders or by the underwriter or underwriters of an underwritten offering of Registrable Securities, if any, unless the Registrable Securities are already so rated;

            (q)   otherwise comply with all applicable rules and regulations of the SEC and make available to its security holders, as soon as reasonably practicable, an earnings statement covering at least twelve (12) months which shall satisfy the provisions of Section 11(a) of the 1933 Act and Rule 158 thereunder; and

            (r)   cooperate and assist in any filings required to be made with the NASD and in the performance of any due diligence investigation by any underwriter and its counsel (including any "qualified independent underwriter" that is required to be retained in accordance with the rules and regulations of the NASD);

        The Company may (as a condition to such Holder's participation in the Shelf Registration) require each Holder of Registrable Securities to furnish to the Company such information regarding such Holder and the proposed distribution by such Holder of such Registrable Securities as the Company may from time to time reasonably request in writing. Each Holder further agrees promptly to furnish to the Company in writing all information required to be disclosed in order to make the information previously furnished to the Company by such Holder not misleading, any other information regarding such Holder and the distribution of such Registrable Securities as may be required to be disclosed in the Registration Statement under applicable law or pursuant to SEC comments and any information otherwise required by the Company to comply with applicable law or regulations. Each Holder further agrees, following termination of the Effectiveness Period, to notify the Company, within ten business days of a request, of the amount of Registrable Securities sold pursuant to the Registration Statement and, in the absence of a response, the Company may assume that all of the Holder's Registrable Securities were so sold.

10


        Each Holder agrees that, upon receipt of any notice from the Company of the happening of any event or the discovery of any facts, each of the kind described in Sections 3(e)(iii), 3(e)(v) or 3(e)(vi) hereof, such Holder will forthwith discontinue disposition of Registrable Securities pursuant to a Registration Statement until receipt by such Holder of (i) the copies of the supplemented or amended Prospectus contemplated by Section 3(h) hereof or (ii) written notice from the Company that the Shelf Registration is once again effective or that no supplement or amendment is required. If so directed by the Company, such Holder will deliver to the Company (at the Company's expense) all copies in such Holder's possession, 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. Nothing in this paragraph shall prevent the accrual of Liquidated Damages on any Securities.

        If any of the Registrable Securities covered by any Registration Statement are to be sold in an underwritten offering, the underwriter or underwriters and manager or managers that will manage such offering will be selected by the Majority Holders of such Registrable Securities included in such offering and shall be reasonably acceptable to the Company. No Holder of Registrable Securities may participate in any underwritten registration hereunder unless such Holder (a) agrees to sell such Holder's Registrable Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements, (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements and (c) provides the Company with the information required in Section 2.1(d) above.

        4.    Indemnification and Contribution.    

            (a)   The Company agrees to indemnify and hold harmless the Initial Purchasers, each Holder, each Person who participates as an underwriter (each, an "Underwriter" or an "underwriter") and each Person, if any, who controls the Initial Purchasers, Holder or Underwriter within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

                (i)  against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement (or any amendment or supplement thereto) pursuant to which Registrable Securities were registered under the 1933 Act, including all documents incorporated therein by reference, or any omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading, or arising out of any untrue statement or alleged untrue statement of a material fact contained in any Prospectus (or any amendment or supplement thereto) or any omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

               (ii)  against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 4(d) below) any such settlement is effected with the written consent of the Company; and

              (iii)  against any and all expense whatsoever, as incurred (including the reasonable fees and disbursements of counsel chosen by any indemnified party), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under subparagraph (i) or (ii) above;

11



    provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Initial Purchasers, any Holder or Underwriter (or any person who expressly controls the Initial Purchasers, Holder or Underwriter) expressly for use in a Registration Statement (or any amendment thereto) or any Prospectus (or any amendment or supplement thereto) provided further that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense if the Holder fails to deliver at or prior to the written confirmation of sale, the most recent Prospectus, as amended or supplemented, and such Prospectus, as amended or supplemented, would have corrected such untrue statement or omission or alleged untrue statement or omission of a material fact and the delivery thereof was required by law.

            (b)   Each Holder, severally but not jointly, agrees to indemnify and hold harmless the Company, the Initial Purchasers, each Underwriter and the other selling Holders, and each of their respective directors and officers, and each Person, if any, who controls the Company, the Initial Purchasers, any Underwriter or any other selling Holder within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 4(a) hereof, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto) or any Prospectus included therein (or any amendment or supplement thereto) in reliance upon and in conformity with written information with respect to such Holder furnished to the Company by or on behalf of such Holder or any other person who controls such Holder expressly for use in the Registration Statement (or any amendment thereto) or such Prospectus (or any amendment or supplement thereto); provided, however, that no such Holder shall be liable for any claims hereunder in excess of the amount of net proceeds received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement.

            (c)   Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action or proceeding commenced against it in respect of which indemnity may be sought hereunder, but failure so to notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying party or parties be liable for the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 4 (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

12



            (d)   If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 4(a)(ii) effected without its written consent if (i) such settlement is entered into more than forty-five (45) days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least thirty (30) days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

            (e)   If the indemnification provided for in this Section 4 is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, in such proportion as is appropriate to reflect the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

        The relative fault of such indemnifying party or parties on the one hand and the indemnified party or parties on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by such indemnifying party or parties or such indemnified party or parties, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

            (f)    The Company, the Holders and the Initial Purchasers agree that it would not be just or equitable if contribution pursuant to this Section 4 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (e) above. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 4 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

        Notwithstanding the provisions of this Section 4, the Initial Purchasers or any Holder or Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which Registrable Securities sold by it pursuant to a Registration Statement were offered exceeds the amount of any damages that the Initial Purchasers, Holder or Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

        No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

        For purposes of this Section 4, each Person, if any, who controls the Initial Purchasers, Holder or Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Initial Purchasers or such Holder or Underwriter, as the case may be, and each director of the Company, each officer of the Company who signed the Registration Statement and each Person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The respective obligations of the Initial Purchasers, Holders, and Underwriters to contribute pursuant to

13



this Section 4 are several in proportion to the principal amount of Securities sold by them pursuant to a Registration Statement and not joint.

        The indemnity and contribution provisions contained in this Section 4 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of the Initial Purchasers or any Holder or Underwriter or any Person controlling the Initial Purchasers, or any Holder or Underwriter, or by or on behalf of the Company, its officers, or directors or any Person controlling the Company and (iii) any sale of Registrable Securities pursuant to a Registration Statement.

        5.    Miscellaneous.    

            5.1    Rule 144 and Rule 144A.    For so long or the Company is subject to the reporting requirements of Section 13 or 15 of the 1934 Act, the Company covenants that it will file the reports required to be filed by it under the 1933 Act and Section 13(a) or 15(d) of the 1934 Act. If the Company ceases to be subject to the reporting requirements of Section 13 or 15 of the 1934 Act, it will upon the request of any Holder or beneficial owner of Registrable Securities (a) make publicly available such information (including, without limitation, the information specified in Rule 144A(d)(4) under the 1933 Act) as is necessary to permit sales pursuant to Rule 144 under the 1933 Act, (b) deliver or cause to be delivered, promptly following a request by any Holder or beneficial owner of Registrable Securities or any prospective purchaser or transferee designated by such Holder or beneficial owner, such information (including, without limitation, the information specified in Rule 144A(d)(4) under the 1933 Act) as is necessary to permit sales pursuant to Rule 144A under the 1933 Act and it will take such further action as any Holder or beneficial owner of Registrable Securities may reasonably request, and (c) take such further action that is reasonable in the circumstances, in each case, to the extent required from time to time to enable such Holder to sell its Registrable Securities without registration under the 1933 Act within the limitation of the exemptions provided by (i) Rule 144 under the 1933 Act, as such Rule may be amended from time to time, (ii) Rule 144A under the 1933 Act, as such Rule may be amended from time to time or (iii) any similar rules or regulations hereafter adopted by the SEC. Upon the request of any Holder or beneficial owner of Registrable Securities, the Company will deliver to such Holder a written statement as to whether it has complied with such requirements.

            5.2    No Inconsistent Agreements.    The Company has not entered into nor will the Company on or after the date of this Agreement enter into any agreement which is inconsistent with the rights granted to the Holders of Registrable Securities in this Agreement or otherwise conflicts with the provisions hereof. The rights granted to the Holders hereunder do not for the term of this Agreement and will not in any way conflict with and are not and will not be inconsistent with the rights granted to the holders of any of the Company's other issued and outstanding securities under any other agreements entered into by the Company or any of its subsidiaries.

            5.3    Amendments and Waivers.    The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the Company has obtained the written consent of Holders of at least a majority in aggregate principal amount of the outstanding Registrable Securities affected by such amendment, modification, supplement, waiver or departure. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders of Registrable Securities whose securities are being sold pursuant to a Registration Statement and that does not directly or indirectly affect the rights of other Holders of Registrable Securities may be given by Holders of at least a majority of the Registrable Securities being sold by such Holders pursuant to such Registration Statement; provided that the provisions of this sentence may not be amended, modified, or supplemented except in accordance with the provisions of the immediately preceding sentence. Each Holder of Registrable Securities outstanding at the time of any such amendment,

14



    modification, supplement, waiver or consent or thereafter shall be bound by any such amendment, modification, supplement, waiver or consent effected pursuant to this Section 5.3, whether or not any notice, writing or marking indicating such amendment, modification, supplement, waiver or consent appears on the Registrable Securities or is delivered to such Holder.

            5.4    Notices.    All notices and other communications provided for or permitted hereunder shall be made in writing by hand delivery, registered first-class mail, telecopier or any courier guaranteeing overnight delivery (a) if to a Holder (other than the Initial Purchasers), at the most current address set forth on the records of the registrar under the Indenture, (b) if to the Initial Purchasers, at the most current address given by the Initial Purchasers to the Company by means of a notice given in accordance with the provisions of this Section 5.4, which address initially is the address set forth in the Purchase Agreement with respect to the Initial Purchasers with a copy to Wilson Sonsini Goodrich & Rosati, Professional Corporation, 650 Page Mill Road, Palo Alto, California 94304, Attention: Robert Claassen, (c) if to the Company, initially at the Company's address set forth in the Purchase Agreement with a copy to Fenwick & West LLP, 801 California Street, Mountain View, California, 94014, Attention: Dennis DeBroeck, and thereafter at such other address of which notice is given in accordance with the provisions of this Section 5.4, and (d) if to any Underwriter, at the most current address given by such Underwriter to the Company by means of a notice given in accordance with the provisions of this Section 5.4, which address initially is the address set forth in the applicable underwriting agreement.

        All such notices and communications shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; two business days after being deposited in the mail, postage prepaid, if mailed; when receipt is acknowledged, if telecopied; and on the next business day if timely delivered to an air courier guaranteeing overnight delivery.

        Copies of all such notices, demands or other communications shall be concurrently delivered by the Person giving the same to the Trustee, at the address specified in the Indenture.

            5.5    Successors and Assigns.    This Agreement shall inure to the benefit of and be binding upon the successors, assigns and transferees of each of the parties, including, without limitation and without the need for an express assignment, subsequent Holders; provided, that (a) this Agreement shall not inure to the benefit of or be binding upon a successor or assign of a Holder unless and to the extent such successor or assign acquires Registrable Securities from a Holder and (b) nothing herein shall be deemed to permit any assignment, transfer or other disposition of Registrable Securities in violation of the terms hereof or of the Purchase Agreement or the Indenture. If any transferee of any Holder shall acquire Registrable Securities, in any manner, whether by operation of law or otherwise, such Registrable Securities shall be held subject to all of the terms of this Agreement, and by taking and holding such Registrable Securities, such Person shall be conclusively deemed to have agreed to be bound by and to perform all of the terms and provisions of this Agreement, including the restrictions on resale set forth in this Agreement and, if applicable, the Purchase Agreement, and such person shall be entitled to receive the benefits hereof.

            5.6    Third Party Beneficiaries.    The Initial Purchasers (even if the Initial Purchasers is not a Holder of Registrable Securities) shall be third party beneficiaries of the agreements made hereunder between the Company, on the one hand, and the Holders, on the other hand, and shall have the right to enforce such agreements directly to the extent they deem such enforcement necessary or advisable to protect their rights or the rights of Holders hereunder. Each Holder of Registrable Securities shall be a third party beneficiary to the agreements made hereunder between the Company, on the one hand, and the Initial Purchasers, on the other hand, and shall have the right to enforce such agreements directly to the extent it deems such enforcement necessary or advisable to protect its rights hereunder.

15



            5.7    Restrictions on Resales    Until the expiration of two years after the original issuance of the Securities, the Company will not, and will cause its "affiliates" (as such terms is defined in Rule 144(a)(1) under the 1933 Act) not to, resell any Securities which are "restricted securities" (or such term is defined under Rule 144(a)(3) under the 1933 Act) that have been reacquired by any of them and shall immediately upon any purchase of any such Securities submit such Securities to the Trustee for cancellation.

            5.8    Headings.    The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof.
