                                        4

                                   of in accordance with the Shelf Registration

         Statement and the related Prospectus in such a manner as to permit such
         Holder to deliver such Prospectus to purchasers of Transfer Restricted
         Securities in accordance with applicable law. None of the Company's
         security holders (other than the Holders of Transfer Restricted

         resold pursuant thereto or shall have otherwise ceased to be Transfer
         Restricted Securities), the Company shall use its reasonable efforts to
         obtain the prompt withdrawal of any order suspending the effectiveness

         Registration Statement covering all of the securities that as of the
         date of such filing are Transfer Restricted Securities (a "Subsequent
         Shelf Registration Statement"). If a Subsequent Shelf Registration
         Statement is filed, the Company shall use its reasonable efforts to
         cause the Subsequent Shelf Registration Statement to become effective
         as promptly as is practicable after such filing and to keep such
         Registration Statement (or subsequent Shelf Registration Statement)
         continuously effective until the end of the Effectiveness Period.

                  (d) The Company shall supplement and amend the Shelf
         Registration Statement if required by the rules, regulations or
         instructions applicable to the registration form used by the Company
         for such Shelf Registration Statement, if required by the Securities
         Act or as reasonably requested by the Initial Purchasers or by the
         Trustee on behalf of the Holders of the Transfer Restricted Securities
         covered by such Shelf Registration Statement.

              (e)     Each Holder agrees that if such Holder wishes to sell
         Transfer Restricted Securities pursuant to a Shelf Registration
         Statement and related Prospectus, it will do so only in accordance with
         this Section 2(e) and Section 4(b). Each Holder wishing to sell
         Transfer Restricted Securities pursuant to a Shelf Registration
         Statement and related Prospectus agrees to deliver a Notice and
         Questionnaire to the Company at least five (5) Business Days prior to
         any intended distribution of Transfer Restricted Securities under the
         Shelf Registration Statement. From and after the date the Shelf
         Registration Statement is declared effective, the Company shall, as
         promptly as practicable after the date a Notice and Questionnaire is
         delivered, and in any event upon the later of (x) five (5) Business
         Days after such date (but no earlier than five (5) Business Days after
         effectiveness) or (y) five (5) Business Days after the expiration of
         any Suspension Period in effect when the Notice and Questionnaire is
         delivered:

                         (i)   if required by applicable law, file with the SEC

              a post-effective amendment to the Shelf Registration Statement or
              prepare and, if required by applicable law, file a supplement to
              the related Prospectus or a supplement or amendment to any
              document incorporated therein by reference or file any other
              required document so that the Holder delivering such Notice and
              Questionnaire is named as a selling securityholder in the Shelf
              Registration Statement and the related Prospectus in such a manner
              as to permit such Holder to deliver such Prospectus to purchasers
              of the Transfer Restricted Securities in accordance with
              applicable law and, if the Company shall file a post-effective
              amendment to the Shelf Registration Statement, use its reasonable
              efforts to cause such post-effective amendment to be declared
              effective under the Securities Act as promptly as is practicable,
              but in any event by the date (the "Amendment Effectiveness
              Deadline Date") that is forty-five (45) days after the date such
              post-effective amendment is required by this clause to be filed;

                        (ii)   provide such Holder copies of any documents filed
              pursuant to Section 2(e)(i); and

                       (iii)   notify such Holder as promptly as practicable
              after the effectiveness under the Securities Act of any
              post-effective amendment filed pursuant to Section 2(e)(i);

provided that if such Notice and Questionnaire is delivered during a Suspension
Period, the Company shall so inform the Holder delivering such Notice and
Questionnaire and shall take the actions set forth in clauses (i), (ii) and
(iii) above

                                       6



upon expiration of the Suspension Period in accordance with Section 4(b).
Notwithstanding anything contained herein to the contrary, (i) the Company shall
be under no obligation to name any Holder that is not a Notice Holder as a
selling securityholder in any Registration Statement or related Prospectus and
(ii) the Amendment Effectiveness Deadline Date shall be extended by up to ten
(10) Business Days from the expiration of a Suspension Period (and the Company
shall incur no obligation to pay Liquidated Damages during such extension) if
such Suspension Period shall be in effect on the Amendment Effectiveness
Deadline Date; and provided further, that after the date that is 180 days after
the date of effectiveness of the Shelf Registration Statement, the Company shall
not be obligated to file more than one post-effective amendment or supplement in
any 30-day period for the purpose of naming Holders as selling securityholders
who were not so named in the Shelf Registration Statement at the time of
effectiveness.

              Effectiveness Deadline Date;

              Shelf Registration Statement is filed and declared effective but,
              during the Effectiveness Period, shall thereafter cease to be
              effective or fail to be usable for its intended purpose without
              being succeeded within five (5) Business Days by a post-effective
              amendment to the Shelf Registration Statement, a supplement to
              the Prospectus or a report filed with the Commission pursuant to
              Section 13(a), 13(c), 14 or 15(d) of the Exchange Act that cures
              such failure and, in the case of a post-effective amendment, is
              itself declared effective within such five (5) Business Day
              period; or

                                       7

              such suspension has not been terminated or (B) Suspension Periods
              exceed an aggregate of 90 days in any 360 day period,

                         continuing, equal to 0.50% per annum of the aggregate
                         principal amount of each Note converted; provided that

         All obligations of the Company set forth in this Section 3 that are
outstanding with respect to any Transfer Restricted Security at the time such
security ceases to be a Transfer Restricted Security shall survive until such
time as all such obligations with respect to such Transfer Restricted Security
shall have been satisfied in full.

         The Liquidated Damages set forth above shall be the exclusive monetary
remedy available to the Holders of Transfer Restricted Securities for each
Registration Default.

         4.  Registration Procedures.

                (a)  In connection with the Shelf Registration Statement, the
         Company shall comply with all the provisions of Section 4(b) hereof
         and shall prepare and file with the Commission a Shelf Registration
         Statement relating to the registration on any appropriate form under
         the Securities Act in accordance with Section 2 hereof.

                (b)  In connection with the Shelf Registration Statement and
         any Prospectus required by this Agreement to permit the sale or resale
         of Transfer Restricted Securities, the Company shall:

                           (i)   Subject to any notice by the Company in
                accordance with this Section 4(b) of the existence of any fact
                or event of the kind described in Section 4(b)(iii)(D), use its
                reasonable efforts to keep the Shelf Registration Statement
                continuously effective during the Effectiveness Period; upon the
                occurrence of any event that would cause the Shelf Registration
                Statement or the Prospectus contained therein (A) to contain a
                material misstatement or omission or (B) not to be effective and
                usable for resale of Transfer Restricted Securities during the
                Effectiveness Period, the Company shall file promptly an
                appropriate amendment to the Shelf Registration Statement, a
                supplement to the Prospectus or a report filed with the
                Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the
                Exchange Act, in the case of clause (A), correcting any such
                misstatement or omission, and, in the case of either clause (A)
                or (B), use its reasonable efforts to cause such amendment to be
                declared effective and the Shelf Registration Statement and the
                related Prospectus to become usable for resale of Transfer
                Restricted Securities during the Effectiveness Period as soon as
                practicable thereafter. Notwithstanding the foregoing, the
                Company may suspend the use of the Prospectus and may elect to
                suspend the effectiveness of the Shelf Registration Statement by
                written notice to the Holders for a period not to exceed an
                aggregate of 45 days in any 90-day period (each such period, a
                "Suspension Period") if:

                                       9



                     (x)    an event occurs and is continuing as a result of
                which the Shelf Registration Statement, the Prospectus, any
                amendment or supplement thereto, or any document incorporated by
                reference therein would, in the Company's judgment, 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

                     (y)    the Company determines in good faith that the
                disclosure of such event at such time would be seriously
                detrimental to the Company and its subsidiaries;

         provided that, in the event the disclosure relates to a previously
         undisclosed proposed or pending material business transaction, the
         disclosure of which the Company determines in good faith would be
         reasonably likely to impede the Company's ability to consummate such
         transaction, the Company may extend a Suspension Period from 45 days to
         60 days; provided, however, that Suspension Periods shall not exceed an
         aggregate of 90 days in any 360-day period. The Company shall not be
         required to specify in the written notice to the Holders the nature of
         the event giving rise to the Suspension Period.

                     (ii)   Prepare and file with the Commission such amendments
                and post-effective amendments to the Shelf Registration
                Statement as may be necessary to keep the Shelf Registration
                Statement effective during the Effectiveness Period; cause the
                Prospectus to be supplemented by any required Prospectus
                supplement, and as so supplemented to be filed pursuant to Rule
                424 under the Securities Act, and to comply fully with the
                applicable provisions of Rules 424 and 430A under the Securities
                Act in a timely manner; and comply with the provisions of the
                Securities Act with respect to the disposition of all securities
                covered by the Shelf Registration Statement during the
                applicable period in accordance with the intended method or
                methods of distribution by the sellers thereof set forth in the
                Shelf Registration Statement or supplement to the Prospectus.

                     (iii)  Advise the selling Holders promptly and, if
                requested by such selling Holders, to confirm such advice in
                writing, except as provided in clause (D) below:

                                 (A)  when the Prospectus or any Prospectus
                     supplement or post-effective amendment has been filed, and,
                     with respect to the Shelf Registration Statement or any
                     post-effective amendment thereto, when the same has become
                     effective;

                                       10



                            (B) of any request by the Commission for amendments
                     to the Shelf Registration Statement or amendments or
                     supplements to the Prospectus or for additional information
                     relating thereto;

                            (C) of the issuance by the Commission of any stop
                     order suspending the effectiveness of the Shelf
                     Registration Statement under the Securities Act or of the
                     suspension by any state securities commission of the
                     qualification of the Transfer Restricted Securities for
                     offering or sale in any jurisdiction, or the initiation of
                     any proceeding for any of the preceding purposes; or

                            (D) of the existence of any fact or the happening
                     of any event, during the Effectiveness Period, that makes
                     any statement of a material fact made in the Shelf
                     Registration Statement, the Prospectus, any amendment or
                     supplement thereto, or any document incorporated by
                     reference therein untrue, or that requires the making of
                     any additions to or changes in the Shelf Registration
                     Statement or the Prospectus in order to make the statements
                     therein not misleading.

         If at any time the Commission shall issue any stop order suspending the
         effectiveness of the Shelf Registration Statement, or any state
         securities commission or other regulatory authority shall issue an
         order suspending the qualification or exemption from qualification of
         the Transfer Restricted Securities under state securities or Blue Sky
         laws, the Company shall use its reasonable efforts to obtain the
         withdrawal or lifting of such order at the earliest possible time and
         will provide to each Holder who is named in the Shelf Registration
         Statement prompt notice of the withdrawal of any such order.

                     (iv)   Make available at reasonable times for inspection by
                one or more representatives of the selling Holders, designated
                in writing by a Majority of Holders whose Transfer Restricted
                Securities are included in the Shelf Registration Statement, and
                any attorney or accountant retained by such selling Holders, all
                financial and other records, pertinent corporate documents and
                properties of the Company as shall be reasonably necessary to
                enable them to conduct a reasonable investigation within the
                meaning of Section 11 of the Securities Act, and cause the
                Company's officers, directors, managers and employees to supply
                all information reasonably requested by any such representative
                or representatives of the selling Holders, attorney or
                accountant in connection therewith; provided, however, that the
                Company shall have no obligation to deliver information to any
                selling Holder or

                                       11



         representative pursuant to this Section 4(b)(iv) unless such selling
         Holder or representative shall have executed and delivered a
         confidentiality agreement in a form reasonably acceptable to the
         Company relating to such information.

                   (v)    If requested by any selling Holders, promptly
         incorporate in the Shelf Registration Statement or Prospectus,
         pursuant to a supplement or post-effective amendment if necessary,
         such information as such selling Holders may reasonably request to
         have included therein, including, without limitation, information
         relating to the "Plan of Distribution" of the Transfer Restricted
         Securities.

                   (vi)   Furnish to each selling Holder upon such Holder's
         written request, without charge, at least one copy of the Shelf
         Registration Statement, as first filed with the Commission, and of each
         amendment thereto (and any documents incorporated by reference therein
         or exhibits thereto (or exhibits incorporated in such exhibits by
         reference) as such Person may request).

                   (vii)  Deliver to each selling Holder, without charge, as
         many copies of the Prospectus (including each preliminary Prospectus)
         and any amendment or supplement thereto as such Persons reasonably may
         request; subject to any notice by the Company in accordance with this
         Section 4(b) of the existence of any fact or event of the kind
         described in Section 4(b)(iii)(D) or 4(b)(i), the Company hereby
         consents to the use of the Prospectus and any amendment or supplement
         thereto by each of the selling Holders in connection with the offering
         and the sale of the Transfer Restricted Securities covered by the
         Prospectus or any amendment or supplement thereto.

                   (viii) Before any public offering of Transfer Restricted
         Securities, cooperate with the selling Holders and their counsel in
         connection with the registration and qualification of the Transfer
         Restricted Securities under the securities or Blue Sky laws of such
         jurisdictions in the United States as the selling Holders may
         reasonably request and do any and all other acts or things necessary or
         advisable to enable the disposition in such jurisdictions of the
         Transfer Restricted Securities covered by the Shelf Registration
         Statement; provided, however, that the Company shall not be required
         (A) to register or qualify as a foreign corporation or a dealer of
         securities where it is not now so qualified or to take any action that
         would subject it to the service of process in any jurisdiction where it
         is not now so subject or (B) to subject itself to general or unlimited
         service of process or to taxation in any such jurisdiction if it is not
         now so subject.

                                       12



                   (ix)   Cooperate with the selling Holders to facilitate the
          timely preparation and delivery of certificates representing Transfer
          Restricted Securities to be sold and not bearing any restrictive
          legends (unless required by applicable securities laws); and enable
          such Transfer Restricted Securities to be in such denominations and
          registered in such names as the Holders may reasonably request at
          least two Business Days before any sale of Transfer Restricted
          Securities made by such Holders.

                   (x)    Subject to Section 4(b)(i) hereof and the provision in
          clause (viii) above, use its reasonable efforts to cause the Transfer
          Restricted Securities covered by the Shelf Registration Statement to
          be registered with or approved by such other U.S. governmental
          agencies or authorities as may be necessary to enable the seller or
          sellers thereof to consummate the disposition of such Transfer
          Restricted Securities.

                   (xi)   Subject to Section 4(b)(i) hereof, if any fact or
          event contemplated by Section 4(b)(iii)(D) hereof shall exist or have
          occurred, use its reasonable efforts to prepare a supplement or
          post-effective amendment to the Shelf Registration Statement or
          related Prospectus or any document incorporated therein by reference
          or file any other required document so that, as thereafter delivered
          to the purchasers of Transfer Restricted Securities, the Prospectus
          will not contain an untrue statement of a material fact or omit to
          state any material fact required to be stated therein or necessary to
          make the statements therein, in light of the circumstances in which
          they are made, not misleading.

                   (xii)  Provide CUSIP numbers for all Transfer Restricted
          Securities not later than the effective date of the Shelf Registration
          Statement and provide the Trustee under the Indenture with
          certificates for the Notes that are in a form eligible for deposit
          with The Depository Trust Company.

                   (xiii) 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 that is required to be retained in
          accordance with the rules and regulations of the NASD.

                   (xiv)  Subject to Section 4(b)(i) hereof, otherwise use its
          reasonable efforts to comply with all applicable rules and regulations
          of the Commission and all reporting requirements under the rules and
          regulations of the Exchange Act.

                                       13



                          (xv)   Cause the Indenture to be qualified under the
                   TIA not later than the effective date of the Shelf
                   Registration Statement required by this Agreement, and, in
                   connection therewith, cooperate with the Trustee and the
                   holders of Notes to effect such changes to the Indenture as
                   may be required for such Indenture to be so qualified in
                   accordance with the terms of the TIA; and execute and use
                   its reasonable efforts to cause the Trustee thereunder to
                   execute all documents that may be required to effect such
                   changes and all other forms and documents required to be
                   filed with the Commission to enable such Indenture to be so
                   qualified in a timely manner.

                          (xvi)  Cause all Common Stock covered by the Shelf
                   Registration Statement to be listed or quoted, as the case
                   may be, on each securities exchange or automated quotation
                   system on which Common Stock is then listed or quoted.

                          (xvii) Provide to each Holder upon written request
                   each document filed with the Commission pursuant to the
                   requirements of Section 13 and Section 15 of the Exchange Act
                   after the effective date of the Shelf Registration Statement,
                   unless such document is available through the Commission's
                   EDGAR system.

                   (c)    Each Holder agrees by acquisition of a Transfer
          Restricted Security that, upon receipt of any notice (a "Suspension
          Notice") from the Company of the existence of any fact of the kind
          described in Section 4(b)(iii)(D) or 4(b)(i) hereof, such Holder will
          forthwith discontinue disposition of Transfer Restricted Securities
          pursuant to the Shelf Registration Statement until:

                          (i)  such Holder has received copies of the
                   supplemented or amended Prospectus contemplated by Section
                   4(b)(xi) hereof; or

                          (ii) such Holder is advised in writing by the Company
                   that the use of the Prospectus may be resumed, and has
                   received copies of any additional or supplemental filings
                   that are incorporated by reference in the Prospectus.

If so directed by the Company, each 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 Transfer Restricted
Securities that was current at the time of receipt of such Suspension Notice.

                   (d)    Each Holder agrees, by acquisition of the Transfer
          Restricted Securities, that no Holder shall be entitled to sell any of
          such Transfer Restricted Securities pursuant to a Registration
          Statement or to receive a Prospectus relating thereto, unless such
          Holder has furnished the Company with a Notice and Questionnaire as
          required pursuant to Section

                                       14



         2(e) hereof (including the information required to be included in such
         Notice and Questionnaire) and the information set forth in the next
         sentence. Each Notice Holder agrees promptly to furnish to the Company
         all information required to be disclosed in order to make the
         information previously furnished to the Company by such Notice Holder
         not misleading and any other information regarding such Notice Holder
         and the distribution of such Transfer Restricted Securities as the
         Company may from time to time reasonably request in writing. Any sale
         of any Transfer Restricted Securities by any Holder shall constitute a
         representation and warranty by such Holder that the information
         relating to such Holder and its plan of distribution is as set forth in
         the Prospectus delivered by such Holder in connection with such
         disposition, that such Prospectus does not as of the time of such sale
         contain any untrue statement of a material fact relating to or provided
         by such Holder or its plan of distribution and that such Prospectus
         does not as of the time of such sale omit to state any material fact
         relating to or provided by such Holder or its plan of distribution
         necessary to make the statements in such Prospectus, in the light of
         the circumstances under which they were made, not misleading.

         5.    Registration Expenses.

         All expenses incident to the Company's performance of or compliance
with this Agreement shall be borne by the Company regardless of whether a Shelf
Registration Statement becomes effective, including, without limitation:

                          (i)   all registration and filing fees and expenses
               (including filings made with the NASD);

                          (ii)  all fees and expenses of compliance with federal
               securities and state Blue Sky or securities laws;

                          (iii) all expenses of printing (including printing of
               Prospectuses and certificates for the Common Stock to be issued
               upon conversion of the Notes) and the Company's expenses for
               messenger and delivery services and telephone;

                          (iv)  all fees and disbursements of counsel to the
               Company;

                          (v)   all application and filing fees in connection
               with listing (or authorizing for quotation) the Common Stock on a
               national securities exchange or automated quotation system
               pursuant to the requirements hereof; and

                          (vi)  all fees and disbursements of independent
               certified public accountants of the Company.

                                       15



         The Company shall bear its internal expenses (including, without
limitation, all salaries and expenses of their officers and employees performing
legal, accounting or other duties), the expenses of any annual audit and the
fees and expenses of any Person, including special experts, retained by the
Company.

         6.  Indemnification And Contribution.

                 (a)    The Company agrees to indemnify and hold harmless each
         Holder of Transfer Restricted Securities (including each Initial
         Purchaser), such Holder's directors, officers, and employees and each
         person, if any, who controls any such Holder within the meaning of the
         Securities Act (each, an "Indemnified Holder"), against any loss,
         claim, damage, liability or expense, joint or several, or any action in
         respect thereof (including, but not limited to, any loss, claim,
         damage, liability or action relating to resales of the Transfer
         Restricted Securities), to which such Indemnified Holder may become
         subject, insofar as any such loss, claim, damage, liability or action
         arises out of, or is based upon:

                        (i)  any untrue statement or alleged untrue statement of
                 a material fact contained in (A) the Shelf Registration
                 Statement as originally filed or in any amendment thereof, in
                 any Prospectus, or in any amendment or supplement thereto or
                 (B) any blue sky application or other document or any amendment
                 or supplement thereto prepared or executed by the Company (or
                 based upon written information furnished by or on behalf of the
                 Company expressly for use in such blue sky application or other
                 document or amendment on supplement) filed in any jurisdiction
                 specifically for the purpose of qualifying any or all of the
                 Transfer Restricted Securities under the securities law of any
                 state or other jurisdiction (such application or document being
                 hereinafter called a "Blue Sky Application"); or

                        (ii) the omission or alleged omission to state therein
                 any material fact required to be stated therein or necessary to
                 make the statements therein, in the light of the circumstances
                 under which they were made, not misleading,

and agrees to reimburse each Indemnified Holder promptly upon demand for any
legal or other expenses reasonably incurred by such Indemnified Holder in
connection with investigating, defending, settling, compromising or paying any
such loss, claim, damage, liability, expense or action; provided, however, that
the Company shall not be liable in any such case to the extent that any such
loss, claim, damage, liability, expense or action arises out of, or is based
upon, any untrue statement or alleged untrue statement or omission or alleged
omission made in reliance upon and in conformity with written information
furnished to the Company by or on behalf of such Holder (or its related
Indemnified Holder) specifically for use therein. The foregoing indemnity
agreement is in addition to any liability which the Company may otherwise have.

                                       16



                 (b) Each Holder, severally and not jointly, agrees to indemnify
         and hold harmless the Company, its directors, officers and employees
         and each person, if any, who controls the Company within the meaning of
         the Securities Act to the same extent as the foregoing indemnity from
         the Company to each such Holder, but only with reference to written
         information relating to such Holder furnished to the Company by or on
         behalf of such Holder specifically for inclusion in the documents
         referred to in the foregoing indemnity. This indemnity agreement set
         forth in this Section shall be in addition to any liabilities which any
         such Holder may otherwise have. In no event shall any Holder, its
         directors, officers or any person who controls such Holder be liable or
         responsible for any amount in excess of the amount by which the net
         proceeds received by such Holder with respect to its sale of Transfer
         Restricted Securities pursuant to a Shelf Registration Statement
         exceeds the amount of any damages that such Holder, its directors,
         officers or any person who controls such Holder has otherwise been
         required to pay by reason of such untrue or alleged untrue statement or
         omission or alleged omission.

                 (c) Promptly after receipt by an indemnified party under this
         Section 6 of notice of any claim or the commencement of any action, the
         indemnified party shall, if a claim in respect thereof is to be made
         against the indemnifying party under this Section 6, notify the
         indemnifying party in writing of the claim or the commencement of that
         action; provided, however, that the failure to notify the indemnifying
         party shall not relieve it from any liability which it may have under
         this Section 6 except to the extent it has been materially prejudiced
         by such failure and, provided, further, that the failure to notify the
         indemnifying party shall not relieve it from any liability which it may
         have to an indemnified party otherwise than under this Section 6. If
         any such claim or action is brought against an indemnified party, and
         it notifies the indemnifying party thereof, the indemnifying party
         shall be entitled to participate therein and, to the extent that it
         wishes, jointly with any other similarly notified indemnifying party,
         to assume the defense thereof with counsel satisfactory to the
         indemnified party. After notice from the indemnifying party to the
         indemnified party of its election to assume the defense of such claim
         or action, the indemnifying party shall not be liable to the
         indemnified party under this Section 6 for any legal or other expenses
         subsequently incurred by the indemnified party in connection with the
         defense thereof other than reasonable costs of investigation; provided,
         however, that the indemnified parties shall have the right to employ a
         single counsel to represent jointly the indemnified parties and their
         officers, employees and controlling persons who may be subject to
         liability arising out of any claim in respect of which indemnity may be
         sought by the indemnified parties against the indemnifying party under
         this Section 6 if the indemnified party shall have

                                       17



         been advised by legal counsel that there may be one or more legal
         defenses available to such indemnified party and their respective
         officers, employees and controlling persons that are different from or
         additional to those available to the indemnifying party, and in that
         event, the fees and expenses of such separate counsel shall be paid by
         the indemnifying party. No indemnifying party shall:

                         (i)  without the prior written consent of the
                   indemnified parties (which consent shall not be unreasonably
                   withheld) settle or compromise or consent to the entry of any
                   judgment with respect to any pending or threatened claim,
                   action, suit or proceeding in respect of which
                   indemnification or contribution may be sought hereunder
                   (whether or not the indemnified parties are actual or
                   potential parties to such claim or action), unless such
                   settlement, compromise or consent includes an unconditional
                   release of such indemnified party from all liability arising
                   out of such claim, action, suit or proceeding, or

                         (ii) be liable for any settlement of any such action
                   effected without its written consent (which consent shall not
                   be unreasonably withheld), but if settled with its written
                   consent or if there be a final judgment for the plaintiff in
                   any such action, the indemnifying party agrees to indemnify
                   and hold harmless any indemnified party from and against any
                   loss of liability by reason of such settlement or judgment in
                   accordance with this Section 6.

                   (d)   The indemnifying party under this Section shall not be
         liable for any settlement of any proceeding effected without its
         written consent, which shall not be withheld unreasonably, but if
         settled with such consent or if there is a final judgment for the
         plaintiff, the indemnifying party agrees to indemnify the indemnified
         party against any loss, claim, damage, liability or expense by reason
         of such settlement or judgment. Notwithstanding the foregoing sentence,
         if at any time an indemnified party shall have validly requested an
         indemnifying party to reimburse the indemnified party for fees and
         expenses of counsel as contemplated by Section 6(c) hereof, the
         indemnifying party agrees that it shall be liable for any settlement of
         any proceeding effected without its written consent if (i) such
         settlement is entered into more than 30 days after receipt by such
         indemnifying party of the aforesaid valid request and (ii) such
         indemnifying party shall not have reimbursed the indemnified party in
         accordance with such valid request prior to the date of such
         settlement. No indemnifying party shall, without the prior written
         consent of the indemnified party, effect any settlement, compromise or
         consent to the entry of judgment in any pending or threatened action,
         suit or proceeding in respect of which any indemnified party is or
         could have been a party and indemnity was or could have been sought
         hereunder by such indemnified party, unless such settlement, compromise
         or consent (x)

                                       18



         includes an unconditional release of such indemnified party from all
         liability on claims that are the subject matter of such action, suit or
         proceeding and (y) 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.

                  (e) If the indemnification provided for in this Section 6
         shall for any reason be unavailable or insufficient to hold harmless an
         indemnified party under Section 6(a) or 6(b) in respect of any loss,
         claim, damage or liability (or action in respect thereof) referred to
         therein, each indemnifying party shall, in lieu of indemnifying such
         indemnified party, contribute to the amount paid or payable by such
         indemnified party as a result of such loss, claim, damage or liability
         (or action in respect thereof):

                            (i)  in such proportion as is appropriate to reflect
                  the relative benefits received by the Company from the
                  offering and sale of the Transfer Restricted Securities on the
                  one hand and a Holder with respect to the sale by such Holder
                  of the Transfer Restricted Securities on the other, or

                            (ii) if the allocation provided by Section (6)(e)(i)
                  is not permitted by applicable law, in such proportion as is
                  appropriate to reflect not only the relative benefits referred
                  to in Section 6(e)(i) but also the relative fault of the
                  Company on the one hand and the Holders on the other in
                  connection with the statements or omissions or alleged
                  statements or alleged omissions that resulted in such loss,
                  claim, damage or liability (or action in respect thereof), as
                  well as any other relevant equitable considerations.

The relative benefits received by the Company on the one hand and a Holder on
the other with respect to such offering and such sale shall be deemed to be in
the same proportion as the total net proceeds from the offering of the Notes
purchased under the Purchase Agreement (before deducting expenses) received by
the Company, on the one hand, bear to the total proceeds received by such Holder
with respect to its sale of Transfer Restricted Securities on the other. The
relative fault of the parties shall be determined by reference to whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
on the one hand or the Holders on the other, the intent of the parties and their
relative knowledge, access to information and opportunity to correct or prevent
such statement or omission. The Company and each Holder agree that it would not
be just and equitable if the amount of contribution pursuant to this Section
6(e) were determined by pro rata allocation or by any other method of allocation
that does not take into account the equitable considerations referred to in the
first sentence of this paragraph (e).

                                       19



         The amount paid or payable by an indemnified party as a result of the
loss, claim, damage or liability, or action in respect thereof, referred to
above in this Section 6 shall be deemed to include, for purposes of this Section
6, any legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending or preparing to defend any such
action or claim.

         Notwithstanding the provisions of this Section 6, no Holder shall be
required to contribute any amount in excess of the amount by which the net
proceeds received by such Holder with respect to its sale of Transfer Restricted
Securities exceeds the amount of any damages which such Holder has otherwise
been required to pay by reason of any 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 Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentation. The Holders' obligations to contribute as provided in this
Section 6(d) are several and not joint.

                 (f) The provisions of this Section 6 shall remain in full force
         and effect, regardless of any investigation made by or on behalf of any
         Holder or the Company or any of the officers, directors or controlling
         persons referred to in Section 6 hereof, and will survive the sale by a
         Holder of Transfer Restricted Securities.

         7. Rule 144A and Rule 144. The Company agrees with each Holder, for so
long as any Transfer Restricted Securities remain outstanding and during any
period in which the Company (i) is not subject to Section 13 or 15(d) of the
Exchange Act, to make available, upon request of any Holder, to such Holder or
beneficial owner of Transfer Restricted Securities in connection with any sale
thereof and any prospective purchaser of such Transfer Restricted Securities
designated by such Holder or beneficial owner, the information required by Rule
144A(d)(4) under the Securities Act in order to permit resales of such Transfer
Restricted Securities pursuant to Rule 144A, and (ii) is subject to Section 13
or 15 (d) of the Exchange Act, to make all filings required thereby in a timely
manner in order to permit resales of such Transfer Restricted Securities
pursuant to Rule 144.

         8. Miscellaneous.

                 (a) Remedies. The Company acknowledges and agrees that any
         failure by the Company to comply with its obligations under Section 2
         hereof may result in material irreparable injury to the Initial
         Purchasers or the Holders for which there is no adequate remedy at law,
         that it will not be possible to measure damages for such injuries
         precisely, and that, in the event of any such failure, the Initial
         Purchasers or any Holder may seek such relief as may be required to
         specifically enforce the Company's obligations under Section 2 hereof.

                                       20



                 (b) No Inconsistent Agreements. The Company will not on or
         after the date hereof, enter into any agreement with respect to its
         securities that is inconsistent with the rights granted to the Holders
         in this Agreement or otherwise conflicts with the provisions hereof. In
         addition, the Company shall not grant to any of its securityholders
         (other than the Holders of Transfer Restricted Securities in such
         capacity) the right to include any of its securities in the Shelf
         Registration Statement provided for in this Agreement other than the
         Transfer Restricted Securities. The Company has not previously entered
         into any agreement (which has not expired or been terminated) granting
         any registration rights with respect to its securities to any Person,
         which rights conflict with the provisions hereof.

                 (c) Amendments and Waivers. This Agreement may not be amended,
         modified or supplemented, and waivers or consents to or departures from
         the provisions hereof may not be given, unless the Company has obtained
         the written consent of a Majority of Holders. Notwithstanding the
         foregoing, a waiver or consent to depart from the provisions hereof,
         with respect to a matter, which relates exclusively to the rights of
         Holders whose securities are being sold pursuant to a Shelf
         Registration Statement and does not directly or indirectly adversely
         affect the rights of other Holders, may be given by the Majority
         Holders, determined on the basis of Notes being sold rather than
         registered under such Shelf Registration Statement.

                 (d) Notices. All notices and other communications provided for
         or permitted hereunder shall be made in writing by hand-delivery,
         first-class mail (registered or certified, return receipt requested),
         telex, facsimile transmission, or air courier guaranteeing overnight
         delivery:

                          (i)  if to a Holder, at the address set forth on the
                 records of the registrar under the Indenture or the transfer
                 agent of the Common Stock, as the case may be; and

                          (ii) if to the Company, initially at its address set
                 forth in the Purchase Agreement,

                           With a copy to:

                           Latham & Watkins
                           135 Commonwealth Drive
                           Menlo Park, California 94025
                           Fax No.: (650) 433-2600
                           Attn: Christopher L. Kaufman

                                       21



         All such notices and communications shall be deemed to have been duly
given: at the time delivered by hand, if personally delivered; five Business
Days after being deposited in the mail, postage prepaid, if mailed; when
answered back, if telexed; when receipt acknowledged, if transmitted by
facsimile; and on the next Business Day, if timely delivered to an air courier
guaranteeing overnight delivery.

         Any party hereto may change the address for receipt of communications
by giving written notice to the others.

                 (e) 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 of Transfer
         Restricted Securities, provided, however, that nothing contained herein
         shall be deemed to permit any assignment, transfer or other disposition
         of Transfer Restricted Securities in violation of the terms of the
         Purchase Agreement or the Indenture. If any transferee of any Holder
         shall acquire Transfer Restricted Securities, in any manner, whether by
         operation of law or otherwise, such Transfer Restricted Securities
         shall be held subject to all the terms of this Agreement, and by taking
         and holding such Transfer Restricted 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.

                 (f) Counterparts. This Agreement may be executed in any number
         of counterparts and by the parties hereto in separate counterparts,
         each of which when so executed shall be deemed to be an original and
         all of which taken together shall constitute one and the same
         agreement.

                 (g) Notes Held by the Company or Their Affiliates. Whenever the
         consent or approval of Holders of a specified percentage of Transfer
         Restricted Securities is required hereunder, Transfer Restricted
         Securities held by the Company or its Affiliates (other than subsequent
         Holders if such subsequent Holders are deemed to be Affiliates solely
         by reason of their holding of such Notes) shall not be counted in
         determining whether such consent or approval was given by the Holders
         of such required percentage.

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

                 (i) Governing Law. This Agreement shall be governed by and
         construed in accordance with the law of the State of New York.

                 (j) Severability. If any one or more of the provisions
         contained herein, or the application thereof in any circumstance, is
         held invalid, illegal or unenforceable, the validity, legality and
         enforceability of

                                       22



         any such provision in every other respect and of the remaining
         provisions contained herein shall not be affected or impaired thereby,
         it being intended that all of the rights and privileges of the parties
         shall be enforceable to the fullest extent permitted by law.

                 (k)   Entire Agreement. This Agreement, together with the
         Purchase Agreement and the Indenture, is intended by the parties as a
         final expression of their agreement and intended to be a complete and
         exclusive statement of the agreement and understanding of the parties
         hereto in respect of the subject matter contained herein. There are no
         restrictions, promises, warranties or undertakings, other than those
         set forth or referred to herein with respect to the registration rights
         granted by the Company with respect to the Transfer Restricted
         Securities. This Agreement supersedes all prior agreements and
         understandings between the parties with respect to such subject matter.

                                       23



         IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first written above.
