     Registration Statement continuously effective, supplemented and amended as
     required by the provisions of Section 4(b) hereof to the extent necessary
     to ensure that (A) it is available for resales by the Holders of Transfer
     Restricted Securities entitled, subject to Section 2(b), to the benefit of
     this Agreement and (B) conforms with the requirements of this Agreement and
     the Securities Act and the rules and regulations of the Commission
     promulgated thereunder as announced from time to time, for a period (the
     "EFFECTIVENESS PERIOD") until the earliest of:

                    (A)  two years following the last date of original issuance

     (b)         At the time the Shelf Registration Statement is declared
effective, each Holder that became a Notice Holder on or prior to the date that
is no fewer than fifteen (15) Business Days prior to such time of effectiveness
shall be 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

Securities) that have the right to include any of the Company's securities in
the Shelf Registration Statement.

     (c)         If the Shelf Registration Statement or any Subsequent Shelf
Registration Statement ceases to be effective for any reason at any time during

in a manner reasonably expected to obtain the withdrawal of the order suspending
the effectiveness thereof, or file an additional Shelf Registration Statement

Restricted Securities (a "SUBSEQUENT SHELF REGISTRATION STATEMENT"). If a
Subsequent Shelf Registration Statement is filed, the Company shall use its
reasonable best 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 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 on
or before the later of (x) forty-five (45) Business Days after the date a Notice
and Questionnaire is delivered or (y) ten (10) Business Days after the
expiration of any Suspension Period in effect when the Notice and Questionnaire
is delivered or put into effect within forty-five (45) Business Days of such
delivery date:

          (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
     commercially 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 sixty (60) 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 upon expiration of the Suspension Period in accordance with Section
4(b). Notwithstanding anything contained herein to the contrary, (i) the Company
shall not be under any obligation to name any Holder that is not a Notice Holder
as a selling securityholder in any Shelf Registration Statement or related
Prospectus, (ii) the Company shall not be obligated to file more than two
post-effective amendments pursuant to this

<Page>

                                                                               6

Section 2(e) in any one fiscal quarter and (iii) 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 not incur any
obligation to pay Additional Interest during such extension) if such Suspension
Period shall be in effect on the Amendment Effectiveness Deadline Date.

     3.          ADDITIONAL INTEREST.

     (a)         If:

          (i)    the Shelf Registration Statement is not filed with the
     Commission prior to or on the Shelf Filing Deadline;

          (ii)   the Shelf Registration Statement has not been declared
     effective by the Commission prior to or on the Effectiveness Target Date;

          (iii)  the Company has failed to perform its obligations set forth in
     Section 2(e) within the time periods required therein;

          (iv)   any post-effective amendment to a Shelf Registration Statement
     filed pursuant to Section 2(e)(i) has not become effective under the
     Securities Act on or prior to the Amendment Effectiveness Deadline Date;

          (v)    except as provided in Section 4(b)(i) hereof, the 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 ten (10)
     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 immediately declared effective; or

          (vi)   the 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 and (A) prior to
     or on the thirtieth (30th) day or the forty-fifth (45th) day, as the case
     may be, of any Suspension Period, such suspension has not been terminated
     or (B) Suspension Periods exceed an aggregate of 120 days in any 360 day
     period,

(each such event referred to in foregoing clauses (i) through (vi), a
"REGISTRATION DEFAULT"), the Company hereby agrees to pay interest ("ADDITIONAL
INTEREST"), with respect to the Transfer Restricted Securities from and
including the day following the Registration Default to (but excluding) the
earlier of (1) the day on which the Registration Default has been cured and (2)
the date the Shelf Registration Statement is no longer required to be kept
effective, in respect of the Debentures, to each holder of Debentures accruing
at a rate of (x) with respect to the first ninety (90)-day period during which a
Registration Default shall have occurred and be continuing, equal to 0.25% per
annum of the outstanding principal amount thereof, and (y) with respect to the
period commencing on the ninety-first (91st) day following the day on which the
Registration

<Page>

                                                                               7

Default shall have occurred and be continuing, equal to 0.50% per annum of the
outstanding principal amount thereof; PROVIDED that in no event shall Additional
Interest accrue at a rate per year exceeding 0.50% of the outstanding principal
amount thereof.

     (b)         All accrued Additional Interest shall be paid in arrears to
Record Holders by the Company on each Additional Interest Payment Date, except
as provided in Section 3(c) hereof. Upon the cure of all Registration Defaults
relating to any particular Debenture, the accrual of Additional Interest with
respect to such Debenture will cease.

     (c)         If the Debentures are surrendered for conversion during a
Registration Default, the Record Holders of the Debentures so surrendered for
conversion will receive on the settlement date all accrued and unpaid Additional
Interest with respect to such Debentures as provided in Section 3(a)(A) hereof
to (but excluding) the conversion date relating to the settlement date.

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

     (a)         In connection with the Shelf Registration Statement, the
Company shall comply with all the provisions of Section 4(b) hereof and shall

sale of the Transfer Restricted Securities, and pursuant thereto, shall as
expeditiously as possible prepare and file with the Commission a Shelf
Registration Statement relating to such registration on any appropriate form
under the Securities Act.

     (b)         In connection with the Shelf Registration Statement and any

     Section 4(b) of the existence of any fact or event of the kind described in
     Section 4(b)(iii)(D), use commercially reasonable efforts to keep the Shelf
     Registration Statement continuously effective during the Effectiveness
     Period; and 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,
     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 commercially reasonable efforts

<Page>

                                                                               8

     to cause such amendment to be declared effective and the Shelf Registration
     Statement and the related Prospectus to become usable for their intended
     purposes as soon as practicable thereafter; EXCEPT that notwithstanding the
     foregoing, the Company may suspend the effectiveness of the Shelf
     Registration Statement (or the use of the Prospectus that is part of the
     Shelf Registration Statement) by written notice to the Holders for a period
     not to exceed an aggregate of thirty (30) days in any ninety (90)-day
     period (PROVIDED, HOWEVER, that if such fact or event relates to a
     previously undisclosed proposed or pending material business transaction,
     the disclosure of which would impede the Company's ability to consummate
     such transaction, the Company may extend the period during which it may
     suspend the Registration Statement to a period not to exceed forty-five
     (45) days in any ninety (90)-day period) (each such period, a "SUSPENSION
     PERIOD") upon:

                    (x)  the occurrence or existence of any fact or the
                 happening of any event 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; or

                    (y)  the occurrence or existence of any corporate
                 development that, in the Company's judgment, makes it
                 appropriate to suspend the effectiveness of the Shelf
                 Registration Statement;

     PROVIDED that the Company will use its reasonable best efforts to ensure
     that the use of the Prospectus may be resumed (A) in the case of clause (x)
     above, as soon as, in the reasonable judgment of the Company, public
     disclosure of such fact or event would not be prejudicial to or contrary to
     the interests of the Company or, if necessary to avoid unreasonable burden
     or expense, as soon as practicable thereafter and (B) in the case of clause
     (y) above, as soon as, in the reasonable judgment of the Company, such
     suspension is no longer appropriate; PROVIDED, HOWEVER, that Suspension
     Periods shall not exceed an aggregate of 120 days in any 360-day period,
     and in no event shall the Company be required to specify in the written
     notice to the Holders the nature of the fact or 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 under the Securities Act in a timely
     manner; and comply with the provisions of the Securities Act with respect
     to the disposition of all Debentures or Shares 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)  (x) 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;

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

                    (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 requires the
                 Company to make changes in the Shelf Registration Statement or
                 the Prospectus contained therein, in order that such Shelf
                 Registration Statement or Prospectus does not 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 (in the case of the Prospectus, in light of
                 the circumstances under which they were made) not misleading.

                 (y) 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 best 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 not have any obligation to deliver
     information to any selling Holder or representative, attorney or accountant
     pursuant to this Section

<Page>

                                                                              10

     4(b)(iv) unless such selling Holder or representative, attorney or
     accountant shall have executed and delivered a confidentiality agreement in
     a form 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 its 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 Holder 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), 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 where it is not now so
     subject.

          (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 request at least two Business Days before any sale
     of Transfer Restricted Securities.

                                                                              11

          (x)    Use their reasonable best 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 their reasonable best 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)  Obtain 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
     Debentures 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)  Otherwise use their reasonable best 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.

          (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 Debentures 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 best 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 Shares 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.

                                                                              12

     (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 or occurrence of any event of the kind
described in Section 4(b)(iii)(D) 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 notice of suspension.

     (d)         Each Holder agrees by acquisition of a Transfer Restricted
Security, that no Holder shall be entitled to sell any of such Transfer
Restricted Securities pursuant to a Shelf 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 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);

<Page>

                                                                              13

          (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 Shares to be issued upon conversion of the
     Debentures) 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 Shares 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.

     The Company shall bear its internal expenses (including, without
limitation, all salaries and expenses of its 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 covered by the Shelf Registration Statement
(including each Initial Purchaser), and its directors, officers, and employees
and each person, if any, who controls any such Holder within the meaning of the
Securities Act or the Exchange 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 or 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

<Page>

                                                                              14

          (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 or expense 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; PROVIDED, FURTHER, that with respect to any such
untrue statement or alleged untrue statement in or omission or alleged omission
from any preliminary prospectus contained in the Shelf Registration Statement,
the indemnity agreement contained in this paragraph shall not inure to the
benefit of any Indemnified Holder to the extent that any such loss, claim,
damage or liability of or with respect to such Indemnified Holder to any person
results from the fact that both (i) a copy of the final prospectus contained in
the Shelf Registration Statement (excluding any documents incorporated by
reference therein) was not sent or given to such person, at or prior to the
written confirmation of the sale of such Transfer Restricted Securities to such
person, and (ii) the untrue statement in or omission from such preliminary
prospectus contained in the Shelf Registration Statement was corrected in such
final prospectus unless such failure to deliver the final prospectus contained
in the Shelf Registration Statement was a result of non-compliance by the
Company with the provisions of Section 4 hereof; PROVIDED, FURTHER, that with
respect to any such untrue statement or alleged untrue statement in or omission
or alleged omission from any prospectus, the indemnity agreement contained in
this paragraph shall not inure to the benefit of any Indemnified Holder to the
extent that any such loss, claim, damage or liability of or with respect to such
Indemnified Holder to any person results from the fact that (i) such prospectus
has been amended or supplemented by the Company in accordance with the terms of
this Agreement, (ii) a copy of the prospectus, as amended or supplemented
(excluding any documents incorporated by reference therein), was not sent or
given to such person at or prior to the written confirmation of the sale of such
Transfer Restricted Securities to such person and (iii) the untrue statement in
or omission from such prospectus was corrected in the prospectus, as
supplemented or amended, unless such failure to deliver the prospectus, as
supplemented or amended, was a result of non-compliance by the Company with the
provisions of Section 4 hereof; PROVIDED, FURTHER, that the indemnity agreement
contained in this paragraph shall not inure to the benefit of any Indemnified
Holder to the extent that any such loss, claim, damage or liability of or with
respect to such Indemnified Holder to any person results from an offer or sale
by the Indemnified Holder of Transfer Restricted Securities during a Suspension
Period, if such Indemnified Holder received a Suspension Notice prior to the
making of such offer or sale. The foregoing indemnity agreement is in addition
to any liability which the Company may otherwise have.

     (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 or the Exchange Act to the same extent as the

<Page>

                                                                              15

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 shall be brought against an indemnified party, and
it shall notify 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 reasonably 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 Holders shall have the right to employ a single counsel to represent jointly
the Holders 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 Holders against the Company under this Section 6 if the Holders
seeking indemnification shall have been advised by legal counsel that there may
be one or more legal defenses available to such Holders and their respective
officers, employees and controlling persons that are different from or
additional to those available to the Company, and in that event, the fees and
expenses of such separate counsel shall be paid by the Company.

     (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 requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel as contemplated by Section 6 hereof, the

<Page>

                                                                              16

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 thirty (30) days after receipt by such indemnifying party
of the aforesaid request and (ii) such indemnifying party shall not have
reimbursed the indemnified party in accordance with such request prior to the
date of such settlement. No indemnifying party shall, without the prior written
consent of the indemnified party (which consent shall not be unreasonably
withheld), 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) 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 indemnifying party or parties on the one hand and
     the indemnified party 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 indemnifying party or parties on the one
     hand and the indemnified party 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
Debentures 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).

<Page>

                                                                              17

     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 total
price at which the Transfer Restricted Securities purchased by it were resold
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(e) 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, 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.          NO PARTICIPATION IN UNDERWRITTEN REGISTRATIONS. No Holder may
participate in any Underwritten Registration hereunder.

     9.          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 obtain such relief as may be
required to specifically enforce the Company's obligations under Section 2
hereof. The Company further agrees to waive the defense in any action for
specific performance that a remedy at law would be adequate.

     (b)         ACTIONS AFFECTING TRANSFER RESTRICTED SECURITIES. The Company
shall not, directly or indirectly, take any action with respect to the Transfer
Restricted Securities as a class that would adversely affect the ability of the
Holders of Transfer Restricted Securities to include such Transfer Restricted
Securities in a registration undertaken pursuant to this Agreement.

     (c)         NO INCONSISTENT AGREEMENTS. . Except for (i) the Stock Purchase
Agreements, dated April 30, 2004, between the Company and certain employees of
InteCap, Inc. and (ii) the Stock Purchase Agreement, dated October 18, 2000,
between the Company and Gordon Rausser, which provide for certain registration
rights upon the filing of a registration statement by the Company, the Company
has not, as of the date hereof, entered into, nor shall it, 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 on or after the date hereof grant to any of its securityholders (other than
the Holders of Transfer Restricted Securities in such capacity) the right to
include any of their securities in the Shelf Registration Statement provided for
in this Agreement other than the Transfer Restricted Securities.

     (d)         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; PROVIDED, HOWEVER, that with respect to any
matter that directly or indirectly adversely affects the rights of any Initial
Purchaser hereunder, the Company shall obtain the written consent of each such
Initial Purchaser against which such amendment, qualification, supplement,
waiver or consent is to be effective. Notwithstanding the foregoing (except the
foregoing proviso), (1) 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 of Holders, determined on the basis
of Debentures or Shares being sold rather than registered under such Shelf
Registration Statement, and (2) this Agreement may be amended or supplemented
without notice to or consent of any Holder to (i) cure any ambiguity or omission
or to correct or supplement any provision contained herein that may be defective
or inconsistent with any other provisions contained herein or (ii) add to the
covenants of the Company such further covenants, restrictions or conditions for
the benefit of the Holders.

     (e)         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.

                                                                              19

given: at the time delivered by hand, if personally delivered; three (3)
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.

     (f)         THIRD PARTY BENEFICIARIES. The Holders shall be the third party
beneficiaries to the agreements made hereunder between the Company, on the one
hand, and the Representative, on the other hand, and shall have the right to
enforce such agreements directly to the extent they may deem such enforcement
necessary or advisable to protect their rights or the rights of Holders
hereunder.

     (g)         SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon
the Company and its respective successors and assigns.

     (h)         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.

     (i)         DEBENTURES 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 Debentures) shall not be counted in determining whether such consent or
approval was given by the Holders of such required percentage.

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

     (k)         GOVERNING LAW. This Agreement shall be deemed to be a contract
made under the laws of the State of New York, and for all purposes shall be
construed in accordance with the laws of the State of New York (including
Section 5-1401 of the New York General Obligations Law or any successor to such
statute).

     (l)         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 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.

     (m)         ENTIRE AGREEMENT. This Agreement 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.

Gordon C. Rausser
[ADDRESS]

     RE:    Stock Purchase Agreement
            ------------------------

Dear Mr. Rausser:

     We are pleased that you are interested in purchasing shares of the Common
Stock, no par value ("Shares") of Charles River Associates Incorporated, a
Massachusetts corporation (the "Company"). The terms on which the Company is
willing to issue Shares to you, and our agreements regarding such Shares are as
follows:

     1.     PURCHASE OF SHARES. In consideration of payment to the Company of
$2,000,000, the Company hereby sells and issues to you, and you hereby purchase
from the Company 180,383 Shares. Upon execution of this Agreement, the Company
will deliver to you a certificate registered in your name representing 180,383
Shares.

     2.     YOUR REPRESENTATIONS AND WARRANTIES. To induce the Company to issue
the Shares to you, you hereby represent, warrant and agree as follows:

            2.1     EXPERIENCE, FINANCIAL CAPABILITY AND SUITABILITY. You are
sufficiently experienced in financial and business matters to be capable of
evaluating the risk of this investment and to make an informed decision relating
thereto. You have the financial capability for making the investment, can afford
a complete loss of the investment, and the investment is a suitable one for you.
You understand that the purchase of the Shares involves a high degree of risk
and there may never be an established market for the Company's capital stock.
The Company's activities will require substantial funds which may not be
available. For this and other reasons, the Company's prospects are highly
speculative. Accordingly, you acknowledge that you may lose your entire
investment in the Company.

            2.2     ACCESS TO INFORMATION. Prior to the execution of this
Agreement, you have had the opportunity to ask questions of and receive answers
from representatives of the Company

<Page>

concerning the finances, operations, business and prospects of the Company and
the opportunity to obtain additional information to verify the accuracy of all
information so obtained.

            2.3     INVESTMENT INTENT. You are acquiring the Shares for your own
account for the purpose of investment and not with a view to, or for sale in
connection with, the distribution thereof, nor with any present intention of
distributing or selling the Shares. The Shares are not being registered under
the Securities Act of 1933 as amended (the "Securities Act") and are not being
registered under any state "blue sky" laws, and the Shares may not be
transferred except in compliance with such laws.

            2.4     ACCREDITED INVESTOR. You are an "accredited investor" as
such term is defined in Rule 501 of Regulation D promulgated by the Securities
Exchange Commission pursuant to the Securities Act.

     3.     RESTRICTIONS ON TRANSFER.

            3.1     SECURITIES LAW RESTRICTIONS. You agree with the Company that
the Shares shall not be pledged, hypothecated, sold or transferred, unless prior
to the proposed pledge, hypothecation, sale or transfer of all or part of such
Shares (a) a Registration Statement on the appropriate form under the Securities
Act and applicable state securities laws with respect to the Shares proposed to
be transferred shall then be effective; or (b) the Company shall have received
an opinion of counsel in form and substance satisfactory to it that such
registration is not required because such transaction complies with rules
promulgated by the Securities and Exchange Commission under the Securities Act
and with applicable state securities laws.

            You understand that the Shares are "restricted securities" as that
term is defined in Rule 144 under the Securities Act and that the Shares must be
held indefinitely unless they are subsequently registered under the Securities
Act or an exemption from such registration is available; and that in the case of
sales in which Rule 144 is not available, compliance with Regulation A under the
Securities Act or some other exemption under the Securities Act will be
required. You understand that there may not be available at the time you wish to
sell your Shares the adequate current public information with respect to the
Company which would permit offers or sales of the Shares under Rule 144. Except
as provided below, the Company has no present intention and is under no
obligation to register the Shares under the Securities Act or any state
securities law, nor to make Rule 144 available.

            3.2     LEGENDING OF SHARES. All certificates representing the
Shares to be issued to you pursuant to this Agreement shall have endorsed
thereon legends substantially as follows:

                    "The securities represented by this certificate have not
                    been registered under the Securities Act of 1933, as amended
                    (the "Act") or any state securities law and may not be sold,
                    pledged, hypothecated or transferred in the absence of an
                    effective registration statement covering these securities
                    under the Act and any applicable state securities laws or an
                    opinion of counsel in form and substance satisfactory to the
                    Company that

                                        2
<Page>

                    registration is not required under the Act or under
                    applicable state securities laws."

            3.3     RIGHT OF FIRST PURCHASE. The Company shall have a right of
first purchase with respect to any Shares you wish to sell (assuming the terms
of Sections 3 and 4 of this Agreement have been satisfied). You shall provide
the company with written notice of your desire to sell such shares, and the
Company shall have the right for a period of 10 business days following receipt
of your notice, to purchase such Shares from you. The per share purchase price
for such sale shall be equal to the average closing price for the Company's
common stock for the ten trading days prior to the Company's receipt of your
notice. If the Company exercises its Right of First Purchase, the purchase and
sale of such Shares shall occur within 10 business days following such exercise.
In the event that the Company fails to exercise its right of first purchase
within such ten-day period, you shall be entitled to sell such Shares at any
time during the subsequent 90 day period. If you do not make such a sale within
such 90-day period, you must again comply with this Section 3.3 prior to any
subsequent sale.

     4.     STOCK PLEDGE. As security for the due and punctual payment by you
when due of any amounts payable by you under that certain $2,000,000
Non-Negotiable Promissory Note of even date herewith issued by you to the
Company (the "Note'), you hereby pledge, assign, transfer and grant to the
Company a security interest in the Shares. In the event that your payment
obligations under the Note become due, you may satisfy such obligations in whole
or in part by selling to the Company any Shares securing such obligations that
you continue to own at that time for a per share price equal to the average
closing price for the Company's common stock for the ten trading days prior to
the date such obligations become due; provided, however, that in the event that
the proceeds from such sale are less than the amount of your payment
obligations, you shall remain liable on a full recourse basis for the
difference. Notwithstanding the foregoing, the Company shall have no obligation
to purchase any Shares from you where such purchase would necessitate disclosure
under the federal securities laws or adversely affect the Company's accounting
treatment of the transactions contemplated by that certain Asset Purchase
Agreement between you and the Company. As security for the pledge granted
herein, you agree that the Company shall hold the certificate evidencing the
Shares (together with stock power executed by you in blank) until such time as
the payment obligation under the Note is satisfied.

     5.     "PIGGYBACK" REGISTRATION RIGHTS. If, on or before the fifth
anniversary of this Agreement, the Company chooses to register any of its
securities under the Securities Act for sale to the public, whether for its own
account or for the account of other security holders or both (except with
respect to registration statements on Forms S-4, S-8 or another form not
available for registering the Shares for sale to the public), the Company will
use its best efforts to cause the Shares to be included in the securities to be
covered by the registration statement proposed to be filed by the Company. In
the event that any registration pursuant to this Section 5 shall be, in whole or
in part, an underwritten public offering, the number of Shares to be included in
such an underwriting may be reduced if and to the extent that the managing
underwriter shall be of the opinion that such inclusion would adversely affect
the marketing of the securities to be sold by the Company therein.
Notwithstanding the foregoing provisions, the Company may withdraw

                                        3
<Page>

any registration statement referred to in this Section 5 without thereby
incurring any liability to you. The Company represents that as of the date of
this Agreement, no third party has demand registration rights with respect to
the Company's Common Stock. If all shares of shareholders exercising piggyback
registration rights cannot be accommodated in any such offering, the shares of
all such shareholders shall be proportionately reduced (based on their relative
number of shares they desire to include in such piggyback registration).

     6.     OTHER AGREEMENTS.

            6.1     FURTHER ASSURANCES. You agree to execute such further
instruments and to take such further action as may reasonably be necessary to
carry out the intent of this Agreement.

            6.2     NO OBLIGATION AS TO EMPLOYMENT. The Company is not by reason
of this Agreement obligated to employ or retain, or continue to employ or
retain, you in any capacity.

            6.3     NOTICES. All notices, requests, consents and other
communications hereunder shall be in writing, shall be addressed to the
receiving party's address set forth above or to such other address as a party
may designate by notice hereunder, and shall be either (i) delivered by hand,
(ii) made by telex, telecopy or facsimile transmission, (iii) sent by overnight
courier, or (iv) sent by registered mail, return receipt requested, postage
prepaid. All notices, requests, consents and other communications hereunder
shall be deemed to have been given either (i) if by hand, at the time of the
delivery thereof to the receiving party at the address of such party set forth
above, (ii) if made by telex, telecopy or facsimile transmission, at the time
that receipt thereof has been acknowledged by electronic confirmation or
otherwise, (iii) if sent by overnight courier, on the next business day
following the day such notice is delivered to the courier service, or (iv) if
sent by registered mail, on the 5th business day following the day such mailing
is made.

            6.4     ENTIRE AGREEMENT. This Agreement embodies the entire
agreement and understanding between the parties hereto with respect to the
subject matter hereof and supersedes all prior oral or written agreements and
understandings relating to the subject matter hereof. No statement,
representation, warranty, covenant or agreement of any kind not expressly set
forth in this Agreement shall affect, or be used to interpret, change or
restrict, the express terms and provisions of this Agreement.

            6.5     MODIFICATIONS AND AMENDMENTS. The terms and provisions of
this Agreement may be modified or amended only by written agreement executed by
all parties hereto.

            6.6     WAIVERS AND CONSENTS. The terms and provisions of this
Agreement may be waived, or consent for the departure therefrom granted, only by
written document executed by the party entitled to the benefits of such terms or
provisions. No such waiver or consent shall be deemed to be or shall constitute
a waiver or consent with respect to any other terms or provisions of this
Agreement, whether or not similar. Each such waiver or consent shall be
effective only in

                                        4
<Page>

the specific instance and for the purpose for which it was given, and shall not
constitute a continuing waiver or consent.

            6.7     ASSIGNMENT. The rights and obligations under this Agreement
may not be assigned by either party hereto without the prior written consent of
the other party.

            6.8     BENEFIT. All statements, representations, warranties,
covenants and agreements in this Agreement shall be binding on the parties
hereto and shall inure to the benefit of the respective successors and permitted
assigns of each party hereto. Nothing in this Agreement shall be construed to
create any rights or obligations except among the parties hereto, and no person
or entity shall be regarded as a third-party beneficiary of this Agreement.

            6.9     GOVERNING LAW. This Agreement and the rights and obligations
of the parties hereunder shall be construed in accordance with and governed by
the law of the Commonwealth of Massachusetts without giving effect to the
conflict of law principles thereof.

            6.10    SEVERABILITY. In the event that any court of competent
jurisdiction shall determine that any provision, or any portion thereof,
contained in this Agreement shall be unreasonable or unenforceable in any
respect, then such provision shall be deemed limited to the extent that such
court deems it reasonable and enforceable, and as so limited shall remain in
full force and effect. In the event that such court shall deem any such
provision, or portion thereof, wholly unenforceable, the remaining provisions of
this Agreement shall nevertheless remain in full force and effect.

            6.11    HEADINGS AND CAPTIONS. The headings and captions of the
various subdivisions of this Agreement are for convenience of reference only and
shall in no way modify, or affect the meaning or construction of any of the
terms or provisions hereof.

            6.12    NO WAIVER OF RIGHTS, POWERS AND REMEDIES. No failure or
delay by a party hereto in exercising any right, power or remedy under this
Agreement, and no course of dealing between the parties hereto, shall operate as
a waiver of any such right, power or remedy under this Agreement by a party
hereto, nor any abandonment or discontinuance of steps to enforce any such
right, power or remedy, shall preclude such party from any other or further
exercise thereof or the exercise of any other right, power or remedy hereunder.
The election of any remedy by a party hereto shall not constitute a waiver of
the right of such party to pursue other available remedies. No notice to or
demand on a party not expressly required under this Agreement shall entitle the
party receiving such notice or demand to any other or further notice or demand
in similar or other circumstances or constitute a waiver of the rights of the
party giving such notice or demand to any other or further action in any
circumstances without such notice or demand.

            6.13    SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All
representations and warranties made by the parties hereto in this Agreement or
in any other agreement, certificate or instrument provided for or contemplated
hereby, shall survive the execution and delivery hereof and any investigations
made by or on behalf of the parties.

                                        5
<Page>

            6.14    NO BROKER OR FINDER. Each of the parties hereto represents
and warrants to the other that no broker, finder or other financial consultant
has acted on its behalf in connection with this Agreement or the transactions
contemplated hereby in such a way as to create any liability on the other. Each
of the parties hereto agrees to indemnify and save the other harmless from any
claim or demand for commission or other compensation by any broker, finder,
financial consultant or similar agent claiming to have been employed by or on
behalf of such party and to bear the cost of legal expenses incurred in
defending against any such claim.

            6.15    COUNTERPARTS. This Agreement may be executed in one or more
counterparts, and by different parties hereto on separate counterparts, each of
which shall be deemed an original, but all of which together shall constitute
one and the same instrument.
