          4.   PARTICIPATION RIGHTS.

          (a)  At least 30 days prior to any Transfer of Stockholder Shares
which are shares of Preferred Stock by the GTCR Investors, the GTCR Investors
shall deliver a written notice (the "PREFERRED SALE NOTICE") to the Company and
the other Stockholders (the "NON-GTCR STOCKHOLDERS") specifying in reasonable
detail the identity of the prospective transferee(s) and the terms and
conditions of the Transfer. The Non-GTCR Stockholders may elect to participate
in the contemplated Transfer by delivering written notice to the GTCR Investors
within 30 days after delivery of the Preferred Sale Notice. If any Non-GTCR
Stockholders have elected to participate in such Transfer, the GTCR Investors
and such Non-GTCR Stockholders will be entitled to sell in the contemplated
Transfer, at the same price and on the same terms, a number of shares of
Preferred Stock equal to the product of (A) the quotient determined by dividing
the number of shares of Preferred Stock owned by such Person by the aggregate
number of outstanding shares of Preferred Stock owned by the GTCR Investors and
the Non-GTCR Stockholders participating in such sale and (B) the number of
shares of Preferred Stock to be sold in the contemplated Transfer.

                                        4
<Page>

          (b)  At least 30 days prior to any Transfer of Stockholder Shares
which are shares of Common Stock by the GTCR Investors, the Bajaj Group or the
Pearlstein Group (collectively, the "SUBJECT STOCKHOLDERS"), the Subject
Stockholder proposing to make such Transfer shall deliver a written notice (the
"COMMON SALE NOTICE") to the Company and the other Stockholders (collectively,
the "NON-SUBJECT STOCKHOLDERS") specifying in reasonable detail the identity of
the prospective transferee(s) and the terms and conditions of the Transfer. The
Non-Subject Stockholders may elect to participate in the contemplated Transfer
by delivering written notice to the Subject Stockholders within 30 days after
delivery of the Common Sale Notice. If any Non-Subject Stockholders have elected
to participate in such Transfer, the Subject Stockholders and such Non-Subject
Stockholders will be entitled to sell in the contemplated Transfer, at the same
price and on the same terms, a number of shares of Common Stock equal to the
product of (i) the quotient determined by dividing the number of shares of
Common Stock owned by such Person by the aggregate number of outstanding shares
of Common Stock owned by the Subject Stockholders and the Non-Subject
Stockholders participating in such sale, and (ii) the number of shares of Common
Stock to be sold in the contemplated Transfer. For purposes of this SECTION
4(b), if a holder of shares of Class B Preferred elects to participate in the
contemplated Transfer, (x) the "number of shares of Common Stock owned" by such
holder shall equal the quotient determined by dividing (1) the aggregate
liquidation value of the shares of Class B Preferred then owned by such holder
(plus all accrued and unpaid dividends thereon), by (2) 81.667% of the
consideration per share of Common Stock to be paid to the Subject Stockholders
by the prospective transferee(s) in the contemplated Transfer, and (y) "the
aggregate number of outstanding shares of Common Stock" shall include the number
of shares of Common Stock owned by such holder as calculated pursuant to clause
(x) above.

          (c)

               (i)    The GTCR Investors will use commercially reasonable
     efforts to obtain the agreement of the prospective transferee(s) to the
     participation of the Non-GTCR Stockholders in any Transfer contemplated by
     Section 4(a), and the GTCR Investors will not transfer any of their
     Stockholder Shares to the prospective transferee(s) unless (A) the
     prospective transferee(s) agrees to allow the participation of the Non-GTCR
     Stockholders at the same price and on the same terms, or (B) the GTCR
     Investors agree to purchase the number of such class of Stockholder Shares
     from the Non-GTCR Stockholders which the Non-GTCR Stockholders would have
     been entitled to sell pursuant to SECTION 4(a) for the consideration per
     share to be paid to the GTCR Investors by the prospective transferee(s).

               (ii)   The Subject Stockholders will use commercially reasonable
     efforts to obtain the agreement of the prospective transferee(s) to the
     participation of the Non-Subject Stockholders in any Transfer contemplated
     by Section 4(b), and the Subject Stockholders will not transfer any of
     their Stockholder Shares to the prospective transferee(s) unless (A) the
     prospective transferee(s) agrees to allow the participation of the
     Non-Subject Stockholders at the same price and on the same terms, or (B)
     the Subject Stockholders agree to purchase the number of such class of
     Stockholder Shares from the Non-Subject Stockholders which the Non-Subject
     Stockholders would have been entitled to sell pursuant to SECTION 4(b) for
     the consideration per share to be paid to the Subject Stockholders by the
     prospective transferee(s).

                                        5

          (d)  Notwithstanding anything to the contrary in any other provision
of this Agreement, this SECTION 4 shall not apply with respect to (i) any
Transfer of Stockholder Shares by any GTCR Investor to or among its Affiliates,
(ii) an Exempt Bajaj Transfer, (iii) an Exempt Pearlstein Transfer, or (iv) a
Public Sale; provided that the restrictions contained in this Agreement will
continue to be applicable to the Stockholder Shares after any Transfer pursuant
to clauses (i), (ii) and (iii) and, as a condition to such Transfer, the
transferee of such Stockholder Shares shall agree in writing to be bound by the
provisions of this Agreement. Upon the Transfer of Stockholder Shares pursuant
to clause (i), (ii) or (iii) of the previous sentence, the transferees will
deliver a written notice to the Company, which notice will disclose in
reasonable detail the identity of such transferee. Notwithstanding the
foregoing, no party hereto shall avoid the provisions of this Agreement by
making one or more Transfers to one or more Affiliates and then disposing of all
or any portion of such party's interest in any such Affiliate.

          (e)  This Section 4 will terminate upon the first to occur of (i) the
consummation of an Approved Sale and (ii) the consummation of a Qualified Public
Offering.

          5.   FIRST REFUSAL RIGHTS.

          (a)  Prior to making any Transfer of Stockholder Shares, any
Stockholder (other than the GTCR Investors) desiring to make such Transfer (the
"TRANSFERRING STOCKHOLDER") will give written notice (the "SALE NOTICE") to the
Company and the holders of Investor Shares (collectively, the "SALE NOTICE
RECIPIENTS"). The Sale Notice will disclose in reasonable detail the identity of
the prospective transferee(s), the number of shares to be transferred and the
terms and conditions of the proposed transfer. Such Transferring Stockholder
will not consummate any Transfer until 45 days after the Sale Notice has been
given to the Sale Notice Recipients, unless the parties to the Transfer have
been finally determined pursuant to this SECTION 5 prior to the expiration of
such 45-day period. (The date of the first to occur of such events is referred
to herein as the "AUTHORIZATION DATE").

          (b)  The Company may elect to purchase all (but not less than all) of
such Stockholder Shares to be transferred upon the same terms and conditions as
those set forth in the Sale Notice by delivering a written notice of such
election to the Transferring Stockholder and the Sale Notice Recipients (other
than the Company) within 20 days after the Sale Notice has been given to the
Company. If the Company has not elected to purchase all of the Stockholder
Shares to be transferred, the holders of Investor Shares may elect to purchase
all (but not less than all) of the Stockholder Shares to be transferred upon the
same terms and conditions as those set forth in the Sale Notice by giving
written notice of such election to such Transferring Stockholder within 25 days
after the Sale Notice has been given to the holders of Investor Shares. If more
than one holder of Investor Shares elects to purchase the Stockholder Shares to
be transferred, the shares of Stockholder Shares to be sold shall be allocated
among the holders of Investor Shares pro rata according to the number of
Investor Shares of the relevant class owned by such holder of Investor Shares on
a fully diluted basis. If neither the Company nor the holders of Investor Shares
elects to purchase all of the Stockholder Shares specified in the Sale Notice,
the Transferring Stockholder may transfer the Stockholder Shares specified in
the Sale Notice at a price and on terms no more favorable to the transferee(s)
thereof than specified in the Sale Notice during the 60-day period immediately
following the Authorization Date. Any

                                        6
<Page>

Stockholder Shares not transferred within such 60-day period will be subject to
the provisions of this SECTION 5 upon subsequent transfer.

          (c)  Notwithstanding anything to the contrary in any other provision
of this Agreement, this SECTION 5 will not apply with respect to (i) any
Transfer of Stockholder Shares by any Stockholder to or among its Affiliates,
(ii) any Transfer of Stockholder Shares to any Investor, (iii) with respect to
an Executive or other Stockholder who is an individual, pursuant to applicable
laws of descent and distribution, (iv) a repurchase of Stockholder Shares by the
Company pursuant to the terms of the Senior Management Agreements, (v) a Public
Sale, (vi) a Sale of the Company, including an Approved Sale (as defined in
SECTION 6(a) hereof), (vii) any Transfer pursuant to SECTION 5(b) of the Senior
Management Agreements, (viii) a Transfer of Stockholder Shares held by the
Pearlstein Purchaser to the Ian Z. Pearlstein Trust and/or the Ivanna V.
Pearlstein Trust, (ix) any Transfers of Stockholder Shares held by the Warrant
Holders in connection with Transfers contemplated by Section 12.05 of the Bridge
Loan Agreement, (x) any Transfer of more than 400,000 Stockholder Shares held by
any Warrant Holder (as such amount is adjusted for stock splits, stock
dividends, stock combinations and similar transactions); provided that if any
Warrant Holder originally acquired less than 400,000 Stockholder Shares (as such
amount is adjusted for stock splits, stock dividends, stock combinations and
similar transactions), such provisions will not apply if and to the extent such
transferee Transfers all, but not less than all, of its Stockholder Shares to
one other Person, or (xi) any Transfer pursuant to the Bajaj Free
Transferability Agreement or the Pearlstein Free Transferability Agreement;
provided that the restrictions contained in this Agreement will continue to be
applicable to the Stockholder Shares after any Transfer pursuant to clauses (i),
(ii), (iii), (vii), (viii), (ix), (x) or (xi) above and the transferee of such
Stockholder Shares shall agree in writing to be bound by the provisions of this
Agreement. Upon the Transfer of Stockholder Shares pursuant to clauses (i),
(ii), (iii), (vii), (viii), (ix), (x) or (xi) of the previous sentence, the
transferees will deliver a written notice to the Company, which notice will
disclose in reasonable detail the identity of such transferee.

          (d)  Notwithstanding anything herein to the contrary, except pursuant
to clause (b) above, in no event shall any Transfer of Stockholder Shares
pursuant to this SECTION 5 be made for any consideration other than cash payable
upon consummation of such Transfer.

          (e)  Notwithstanding the foregoing, no Transfer shall be made to a
Person reasonably determined by the Company to be a competitor of the Company or
any of its subsidiaries.

          (f)  This SECTION 5 shall terminate with respect to each Stockholder
Share upon the earlier of (i) consummation of a Qualified Public Offering, (ii)
the consummation of an Approved Sale and (iii) the date on which such
Stockholder Share has been transferred pursuant to this SECTION 5 (other than
SECTIONS 5(c)(i), (iii), (vii), (viii), (ix), (x) OR (xi)).

          6.   SALE OF THE COMPANY.

          (a)  If the holders of a majority of the Investor Shares approve a
Sale of the Company to an Independent Third Party (an "APPROVED SALE"), each
holder of Stockholder Shares shall vote for, consent to and raise no objections
against such Approved Sale. If the

                                        7
<Page>

Approved Sale is structured as a (i) merger, consolidation or other similar
transaction for which dissenters' rights, appraisal rights or similar rights are
available, each holder of Stockholder Shares shall waive any dissenters' rights,
appraisal rights or similar rights in connection with such merger, consolidation
or other similar transaction for which dissenters' rights, appraisal rights or
similar rights are available or (ii) sale of stock, each holder of Stockholder
Shares shall agree to sell all of his Stockholder Shares and rights to acquire
Stockholder Shares on the terms and conditions approved by the Board and the
holders of a majority of the Investor Shares (voting as a single class) then
outstanding. Each holder of Stockholder Shares shall take all necessary or
desirable actions in connection with the consummation of the Approved Sale as
reasonably requested by the Company.

          (b)  The obligations of the holders of Stockholder Shares with respect
to the Approved Sale of the Company are subject to the satisfaction of the
following conditions: (i) upon the consummation of the Approved Sale, each
holder of a particular class of Stockholder Shares shall receive the same form
of consideration and the same amount of consideration per share, (ii) if any
holders of a class of Stockholder Shares are given an option as to the form and
amount of consideration to be received, each holder of such class of Stockholder
Shares shall be given the same option, and (iii) each holder of then currently
exercisable rights to acquire shares of a class of Stockholder Shares shall be
given an opportunity to either (A) exercise such rights prior to the
consummation of the Approved Sale and participate in such sale as holders of
such class of Stockholder Shares or (B) upon the consummation of the Approved
Sale, receive in exchange for such rights consideration equal to the amount
determined by multiplying (1) the same amount of consideration per share of a
class of Stockholder Shares received by holders of such class of Stockholder
Shares in connection with the Approved Sale less the exercise price per share of
such class of Stockholder Shares or such rights to acquire such class of
Stockholder Shares by (2) the number of shares of such class of Stockholder
Shares represented by such rights.

          (c)  If either the Company or the holders of the Stockholder Shares
enter into a negotiation or transaction for which Rule 506 (or any similar rule
then in effect) promulgated by the Securities and Exchange Commission may be
available with respect to such negotiation or transaction (including a merger,
consolidation or other reorganization), the holders of Stockholder Shares will,
at the request of the Company, appoint a purchaser representative (as such term
is defined in Rule 501) reasonably acceptable to the Company. If any holder of
Stockholder Shares appoints a purchaser representative designated by the
Company, the Company will pay the fees of such purchaser representative, but if
any holder of Stockholder Shares declines to appoint the purchaser
representative designated by the Company such holder will appoint another
purchaser representative if necessary to comply with Rule 506, and such holder
will be responsible for the fees of the purchaser representative so appointed.

          (d)  Holders of Stockholder Shares will bear their pro rata share
(based upon the number of shares sold) of the reasonable out of pocket costs of
any sale of such Stockholder Shares pursuant to an Approved Sale to the extent
such costs are incurred for the benefit of all holders of Stockholder Shares and
are not otherwise paid by the Company or the acquiring party. For purposes of
this SECTION 6(d), costs incurred in exercising reasonable efforts to take all
actions in connection with the consummation of an Approved Sale in accordance
with SECTION 6(a) shall be deemed to be for the benefit of all holders of the
Stockholder Shares. Costs

                                        8
<Page>

incurred by holders of Stockholder Shares on their own behalf will not be
considered costs of the transaction hereunder.

          (e)  This SECTION 6 shall terminate with respect to each Stockholder
Share upon the earlier of (i) the consummation of a Qualified Public Offering
and (ii) the consummation of an Approved Sale.

          7.   VOTING REQUIREMENT.

          (a)  During the term of this Agreement and while the exemption
pursuant to Section 280G(b)(5)(A) of the Code is available, each Stockholder
shall vote all of his Stockholder Shares and any other voting securities of the
Company over which such Stockholder has voting control and shall take all other
necessary or desirable actions within his control, and the Company shall take
all necessary and desirable actions within its control (including, without
limitation, calling a special stockholder meeting for such purpose, preparing
and distributing appropriate disclosure documents in connection therewith and
recommending that the Stockholders approve all proposals related thereto) to
approve any payment or benefit to be received by Bajaj or Pearlstein in
connection with a "change in ownership or control" (as such term is defined in
Section 280G of the Internal Revenue Code of 1986, as amended (the "CODE")), (a
"CHANGE OF CONTROL") of the Company or DigitalNet, under the Senior Management
Agreements, including, without limitation, any severance payment and the vesting
of any unvested securities of the Company (the "PAYMENT PROVISIONS").

          (b)  Promptly following the execution of this Agreement, (i) the
Company will prepare and distribute to the Stockholders a disclosure document
describing the Payment Provisions relating to Bajaj and Pearlstein in all
material respects and requesting the Stockholders' approval thereof (the "2001
CONSENT REQUEST") and (ii) the Stockholders agree to vote in favor of, or
consent to, the 2001 Consent Request.

          (c)  The Company shall condition the issuance of any of the voting
securities of the Company (including, without limitation, any voting securities

offering of its capital stock to the public pursuant to an effective

          NOW, THEREFORE, in consideration of the mutual covenants contained
herein and other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties to this Amendment hereby agree as
follows:

          1.   BOARD OF DIRECTORS. Upon the date hereof, Section 1(a) of the
Stockholders Agreement is amended to read in its entirety as follows:

          (a) From and after the Closing and until the provisions of this
Section 1 cease to be effective, each Stockholder shall vote all of his
Stockholder Shares and any other voting securities of the Company over which
such Stockholder has voting control and shall take all other necessary or
desirable actions within his control (whether in his capacity as a stockholder,
director, member of the board or any committee thereof, or officer of the
Company or otherwise, and including, without limitation, attendance at meetings
in person or by proxy for purposes of obtaining a quorum and execution of
written consents in lieu of meetings), and the Company shall take all necessary
and desirable actions within its control (including, without limitation, calling
special board and stockholder meetings), so that:

               (i)   the  authorized  number of directors on the Company's board
     of directors (the "BOARD") shall be no more than nine directors;

               (ii)  the following persons shall be elected to the Board:

                     (A) two representatives designated by GTCR Fund VII (the
          "GTCR INVESTOR DIRECTORS"), who shall initially be Bruce V. Rauner and
          Philip A. Canfield;

                     (B) two representatives designated by Bajaj (the "EXECUTIVE
          DIRECTORS"), who shall be executive officers of the Company and one of
          whom shall initially be Bajaj; and

                     (C) at such time as GTCR Fund VII designates, up to five
          representatives chosen jointly by GTCR Fund VII and Bajaj (the
          "OUTSIDE DIRECTORS"); PROVIDED that no Outside Director shall be a
          member of the Company's management or an employee or officer of the
          Company or its subsidiaries; PROVIDED further that if GTCR Fund VII
          and Bajaj are unable to agree on the Outside Directors within 10 days
          after the date specified by GTCR Fund VII for electing the Outside
          Directors, then GTCR Fund VII shall, in its sole discretion, designate
          the Outside Directors;

               (iii) the composition of any committee of the Board shall include
     at least one GTCR Investor Director;

               (iv)  a majority of the board of directors of each of the
     Company's subsidiaries (a "SUB BOARD") shall consist of members of the
     Board;

                                        2
<Page>

               (v)   the removal from the Board, a Sub Board or a committee
     (with or without cause) of any GTCR Investor Director or any Outside
     Director shall be upon (and only upon) the written request of GTCR Fund
     VII;

               (vi)  the removal from the Board, a Sub Board or a committee
     (with or without cause) of any Executive Director shall be upon (and only
     upon) the written request of Bajaj; and

               (vii) in the event that any representative designated hereunder
     for any reason ceases to serve as a member of the Board, a Sub Board or a
     committee during his term of office, the resulting vacancy on the Board,
     the Sub Board or such committee shall be filled by a representative
     designated by the person or persons originally entitled to designate such
     director pursuant to SECTION 1(a)(ii) above.

          2.   TERMINATION OF THE STOCKHOLDERS AGREEMENT. Upon the consummation
of the Qualified Public Offering planned by the Company, the Stockholders
Agreement shall terminate and have no further force or effect.

          3.   AMENDMENT AND WAIVER. Except as otherwise provided herein, no
modification, amendment or waiver of any provision of this Amendment shall be
effective unless such modification, amendment or waiver is approved in writing
by the Company and the holders of a majority of the Investor Shares; provided
that in the event that such modification, amendment or waiver would adversely
affect a holder or group of holders of Stockholder Shares, then such amendment
or waiver will require the consent of such holder of Stockholder Shares or a
majority of the Stockholder Shares held by such group of holders adversely
affected. The failure of any party to enforce any of the provisions of this
Amendment shall in no way be construed as a waiver of such provisions and shall
not affect the right of such party thereafter to enforce each and every
provision of this Amendment in accordance with its terms.

          4.   SEVERABILITY. Whenever possible, each provision of this Amendment
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Amendment is held to be invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability shall not affect
any other provision or any other jurisdiction, but this Amendment shall be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

          5.   ENTIRE AGREEMENT. Except as otherwise expressly set forth herein,
this document embodies the complete agreement and understanding among the
parties hereto with respect to the subject matter hereof and supersedes and
preempts any prior understandings, agreements or representations by or among the
parties, written or oral, which may have related to the subject matter hereof in
any way.

<Page>

          6.   SUCCESSORS AND ASSIGNS. Except as otherwise provided herein, this
Amendment shall bind and inure to the benefit of and be enforceable by the
Company and its successors and assigns and the Stockholders and any subsequent
holders of Stockholder Shares and the respective successors and assigns of each
of them, so long as they hold Stockholder Shares.

          7.   COUNTERPARTS. This Amendment may be executed in separate
counterparts (including by means of telecopied signature pages), each of which
shall be an original and all of which taken together shall constitute one and
the same agreement.

          8.   REMEDIES. The Company, each Investor, each Executive, Getronics,
the Warrant Holders and each Other Stockholder shall be entitled to enforce
their rights under this Amendment specifically to recover damages by reason of
any breach of any provision of this Amendment and to exercise all other rights
existing in their favor. The parties hereto agree and acknowledge that money
damages may not be an adequate remedy for any breach of the provisions of this
Amendment and that the Company, each Investor, each Executive, Getronics, the
Warrant Holders and each Other Stockholder may in its sole discretion apply to
any court of law or equity of competent jurisdiction for specific performance
and/or injunctive relief (without posting a bond or other security) in order to
enforce or prevent any violation of the provisions of this Amendment.

          9.   GOVERNING LAW. The corporate law of Delaware shall govern all
issues concerning the relative rights of the Company and its stockholders. All
other questions concerning the construction, validity and interpretation of this
Amendment shall be governed by and construed in accordance with the internal
laws of the State of Delaware, without giving effect to any choice of law or
other conflict of law provision or rule (whether of the State of Delaware or any
other jurisdiction) that would cause the application of the laws of any
jurisdiction other than the State of Delaware.

          10.  DESCRIPTIVE HEADINGS. The descriptive headings of this Amendment
are inserted for convenience only and do not constitute a part of this
Amendment.

and

          WHEREAS, the execution and delivery of this Agreement is a condition

          NOW, THEREFORE, in consideration of the mutual covenants contained
herein and other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties to this Agreement hereby agree as
follows:

          1.   DEMAND REGISTRATIONS.

          (a)  REQUESTS FOR REGISTRATION. At any time, the holders of a majority
of the Investor Registrable Securities and, if after a failure to repay the
Bridge Loan Obligations in full in cash on or prior to August 26, 2003, or if
DigitalNet exercises the Extension Option (as defined in the Warrant Agreement)
on or prior to November 26, 2003, at any time after the date that is six-months
after the Company's initial public offering, the holders of a majority of the
Warrant Holder Registrable Securities, may request registration under the
Securities Act of all or any portion of their Registrable Securities on Form S-1
or any similar long-form registration ("LONG-FORM REGISTRATIONS"), or on Form
S-2 or S-3 (including pursuant to Rule 415 under the Securities Act) or any
similar short-form registration ("SHORT-FORM REGISTRATIONS"), if available. All
registrations requested pursuant to this SECTION 1(a) are referred to herein as
"DEMAND REGISTRATIONS." Each request for a Demand Registration shall specify the
approximate number of Registrable Securities requested to be registered and the
anticipated per share price range for such offering. Within ten days after
receipt of any such request, the Company shall give written notice of such
requested registration to all other holders of Registrable Securities and shall
include in such registration all Registrable Securities with respect to which
the Company has received written requests for inclusion therein within 15 days
after the receipt of the Company's notice.

          (b)  INVESTOR LONG-FORM REGISTRATIONS. The holders of Investor
Registrable Securities shall be entitled to request (i) four Long-Form
Registrations in which the Company shall pay all Registration Expenses
("COMPANY-PAID LONG-FORM REGISTRATIONS") and (ii) an unlimited number of
Long-Form Registrations in which the holders of Registrable Securities shall pay
their share of the Registration Expenses (as defined in SECTION 5). No Long-Form
Registration shall count as a Company-Paid Long-Form Registration unless the
holders of Investor Registrable Securities are able to register and sell at
least 90% of the Investor Registrable Securities requested to be included in
such registration; provided that in any event the Company shall pay all
Registration Expenses in connection with any registration initiated as a
Company-Paid Long-Form Registration whether or not it has become effective and
whether or not such registration has counted as one of the permitted
Company-Paid Long-Form Registrations. All Long-Form Registrations shall be
underwritten registrations.

                                      - 2 -

          (c)  INVESTOR SHORT-FORM REGISTRATIONS. In addition to the Long-Form
Registrations provided pursuant to SECTION 1(b), the holders of Investor
Registrable Securities shall be entitled to request an unlimited number of
Short-Form Registrations in which the Company shall pay all Registration
Expenses. Demand Registrations shall be Short-Form Registrations whenever the
Company is permitted to use any applicable short form. After the Company has
become subject to the reporting requirements of the Securities Exchange Act, the
Company shall use its reasonable best efforts to make Short-Form Registrations
on Form S-3 available for the sale of Registrable Securities. If the Company,
pursuant to the request of the holder(s) of a majority of Investor Registrable
Securities, is qualified to and has filed with the Securities and Exchange
Commission a registration statement under the Securities Act on Form S-3
pursuant to Rule 415 under the Securities Act (the "REQUIRED REGISTRATION"),
then the Company shall use its reasonable best efforts to cause the Required
Registration to be declared effective under the Securities Act as soon as
practicable after filing, and, once effective, the Company shall use its
reasonable best efforts to cause such Required Registration to remain effective
for a period ending on the earlier of (i) the date on which all Investor
Registrable Securities have been sold pursuant to the Required Registration or
(ii) the date as of which the holder(s) of Investor Registrable Securities
(assuming such holder(s) are affiliates of the Company) are able to sell all of
the Investor Registrable Securities then held by them within a ninety-day period
in compliance with Rule 144 under the Securities Act.

          (d)  WARRANT HOLDER LONG-FORM REGISTRATION. Unless a Short-Form
Registration is available, the holders of Warrant Holder Registrable Securities
shall be entitled to request one Long-Form Registration in which the Company
shall pay all Registration Expenses ("COMPANY-PAID WARRANT HOLDER LONG-FORM
REGISTRATION"). No Long-Form Registration shall count as the Company-Paid
Warrant Holder Long-Form Registration unless the holders of Warrant Holder
Registrable Securities are able to register and sell at least 90% of the Warrant
Holder Registrable Securities requested to be included in such registration;
provided that in any event the Company shall pay all Registration Expenses in
connection with any registration initiated as a Company-Paid Warrant Holder
Long-Form Registration whether or not it has become effective and whether or not
such registration has counted as one of the permitted Company-Paid Warrant
Holder Long-Form Registration. All Long-Form Registrations shall be underwritten
registrations.

          (e)  WARRANT HOLDER SHORT-FORM REGISTRATIONS. If a Short-Form
Registration is available, then in lieu of the Long-Form Registration provided
pursuant to SECTION 1(d), the holders of Warrant Holder Registrable Securities
shall be entitled to request one Short-Form Registration in which the Company
shall pay all Registration Expenses (the "COMPANY-PAID WARRANT HOLDER SHORT-FORM
REGISTRATION"). Demand Registrations shall be Short-Form Registrations whenever
the Company is permitted to use any applicable short form. After the Company has
become subject to the reporting requirements of the Securities Exchange Act, the
Company shall use its reasonable best efforts to make Short-Form Registrations
on Form S-3 available for the sale of Registrable Securities. No Short-Form
Registration shall count as the Company-Paid Warrant Holder Short-Form
Registration unless the holders of Warrant Holder Registrable Securities are
able to register and sell at least 90% of the Warrant Holder Registrable
Securities requested to be included in such registration; provided that in any
event the Company shall pay all Registration Expenses in connection with any
registration initiated as the Company-Paid Warrant Holder Short-Form
Registration whether or not it has

                                      - 3 -

become effective and whether or not such registration has counted as the
permitted Company-Paid Warrant Holder Short-Form Registration.

          (f)  PRIORITY ON DEMAND REGISTRATIONS. The Company shall not include
in any Demand Registration any securities which are not Registrable Securities
without the prior written consent of the holders of a majority of the
Registrable Securities included in such registration. If a Demand Registration
is an underwritten offering and the managing underwriters advise the Company in
writing that, in their opinion, the number of Registrable Securities and, if
permitted hereunder, other securities requested to be included in such offering
exceeds the number of Registrable Securities and other securities, if any, which
can be sold in an orderly manner in such offering within a price range
acceptable to the holders of a majority of the Registrable Securities to be
included in such registration therein, without adversely affecting the
marketability of the offering, then the Company shall include in such
registration, prior to the inclusion of any securities which are not Registrable
Securities, the number of Registrable Securities requested to be included which,
in the opinion of such underwriters, can be sold in an orderly manner within the
price range of such offering, pro rata among the respective holders thereof on
the basis of the amount of Registrable Securities owned by each such holder.
Unless consented to by the Company and the holders of a majority of the
Registrable Securities included in such registration, any Person other than
holders of Registrable Securities which participates in Demand Registrations
that are not at the Company's expense shall pay their share of the Registration
Expenses in accordance with SECTION 5 hereof.

          (g)  RESTRICTIONS ON LONG-FORM REGISTRATIONS. The Company shall not be
obligated to effect any Long-Form Registration within 90 days after the
effective date of a previous Long-Form Registration or a previous registration
in which the holders of Registrable Securities were given piggyback rights
pursuant to SECTION 2 and in which there was no reduction in the number of
Registrable Securities requested to be included. The Company may postpone for up
to 180 days the filing or the effectiveness of a registration statement for a
Demand Registration requested by the holders of a majority of the Investor
Registrable Securities if the Company and the holders of a majority of the
Investor Registrable Securities agree that such Demand Registration would
reasonably be expected to have a material adverse effect on any proposal or plan
by the Company or any of its Subsidiaries to acquire financing, engage in any
acquisition of assets (other than in the ordinary course of business), or engage
in any merger, consolidation, tender offer, reorganization, or similar
transaction; PROVIDED THAT, in such event, the holders of the Investor
Registrable Securities initially requesting such Demand Registration shall be
entitled to withdraw such request, and the Company shall pay all Registration
Expenses in connection with such registration. The Company may postpone for up
to 180 days the filing or the effectiveness of a registration statement for a
Demand Registration requested by the holders of a majority of the Warrant Holder
Registrable Securities if the Company believes that such Demand Registration
would reasonably be expected to have a material adverse effect on any proposal
or plan by the Company or any of its Subsidiaries to acquire financing, engage
in any acquisition of assets (other than in the ordinary course of business), or
engage in any merger, consolidation, tender offer, reorganization, or similar
transaction; PROVIDED THAT, in such event, the holders of the Warrant Holder
Registrable Securities initially requesting such Demand Registration shall be
entitled to withdraw such request, and the Company shall pay all Registration
Expenses in connection with such registration. The Company may delay a Demand
Registration requested by the holders of a

                                      - 4 -
<Page>

majority of the Investor Registrable Securities hereunder only once in any
twelve-month period, and the Company may delay a Demand Registration requested
by the holders of a majority of the Warrant Holder Registrable Securities
hereunder only once in any twelve-month period.

          (h)  SELECTION OF UNDERWRITERS. The holders of a majority of the
Registrable Securities included in any Demand Registration shall have the right
to select the investment banker(s) and manager(s) to administer the offering;
provided, however, that such investment banker(s) and manager(s) shall be
approved by the Company's Board of Directors, which approval shall not be
unreasonably withheld.

          (i)  OTHER REGISTRATION RIGHTS. Except as provided in this Agreement,
the Company shall not grant to any Persons the right to request the Company to
register any equity securities of the Company, or any securities, options, or
rights convertible or exchangeable into or exercisable for such securities,
without the prior written consent of the holders of a majority of the Investor
Registrable Securities.

          2.   PIGGYBACK REGISTRATIONS.

          (a)  RIGHT TO PIGGYBACK. Whenever the Company proposes to register any
of its securities (including any proposed registration of the Company's
securities by any third party) under the Securities Act (other than (i) pursuant
to a Demand Registration to which SECTION 1 is applicable, (ii) in connection
with an initial public offering of the Company's equity securities, or (iii) in
connection with registrations on Form S-4, Form S-8 or any successor or similar
forms) and the registration form to be used may be used for the registration of
Registrable Securities (a "PIGGYBACK REGISTRATION"), the Company shall give
prompt written notice (and in any event within three business days after its
receipt of notice of any exercise of demand registration rights other than under
this Agreement) to all holders of Registrable Securities of its intention to
effect such a registration and shall include in such registration all
Registrable Securities with respect to which the Company has received written
requests for inclusion therein within 15 days after the receipt of the Company's
notice.

          (b)  PIGGYBACK EXPENSES. The Registration Expenses of the holders of
Registrable Securities shall be paid by the Company in all Piggyback
Registrations, whether or not such registration is consummated.

          (c)  PRIORITY ON PRIMARY REGISTRATIONS. If a Piggyback Registration is
an underwritten primary registration on behalf of the Company, and the managing
underwriters advise the Company in writing that, in their opinion, the number of
securities requested to be included in such registration exceeds the number
which can be sold in an orderly manner in such offering within a price range
acceptable to the Company, then the Company shall include in such registration
(i) first, the securities the Company proposes to sell, (ii) second, the
Registrable Securities requested to be included in such registration, pro rata
among the holders of such Registrable Securities on the basis of the number of
shares owned by each such holder and (iii) third, the other securities requested
to be included in such registration.

          (d)  PRIORITY ON SECONDARY REGISTRATIONS. If a Piggyback Registration
is an underwritten secondary registration on behalf of holders of the Company's
securities other than

                                      - 5 -
<Page>

holders of Registrable Securities (it being understood that secondary
registrations on behalf of holders of Investor Registrable Securities and
Warrant Holder Registrable Securities are addressed in SECTION 1 above rather
than this SECTION 2(d)), and the managing underwriters advise the Company in
writing that, in their opinion, the number of securities requested to be
included in such registration exceeds the number which can be sold in an orderly
manner in such offering within a price range acceptable to the holders of a
majority of the Registrable Securities to be included in such registration, then
the Company shall include in such registration (i) first, the securities
requested to be included therein by the holders requesting such registration,
(ii) second, the Registrable Securities requested to be included in such
registration, pro rata among the holders of such Registrable Securities on the
basis of the number of shares owned by each such holder and (iii) third, the
other securities requested to be included in such registration.

          (e)  SELECTION OF UNDERWRITERS. If any Piggyback Registration is an
underwritten offering, then the selection of investment banker(s) and manager(s)
for the offering must be approved by the holders of a majority of the Investor
Registrable Securities included in such Piggyback Registration. Such approval
shall not be unreasonably withheld.

          (f)  OTHER REGISTRATIONS. If the Company has previously filed a
registration statement with respect to Registrable Securities pursuant to
SECTION 1 or pursuant to this SECTION 2, and if such previous registration has
not been withdrawn or abandoned, then, unless such previous registration is a
Required Registration, the Company shall not file or cause to be effected any
other registration of any of its equity securities or securities convertible or
exchangeable into or exercisable for its equity securities under the Securities
Act (except on Form S-8 or any successor form), whether on its own behalf or at
the request of any holder or holders of such securities, until a period of at
least 180 days has elapsed from the effective date of such previous
registration.

          3.   HOLDBACK AGREEMENTS.

          (a)  To the extent not inconsistent with applicable law, no holder of
Registrable Securities shall effect any public sale or distribution (including
sales pursuant to Rule 144 of the Securities Act) of equity securities of the
Company, or any securities, options, or rights convertible into or exchangeable
or exercisable for such securities, during the seven days prior to and the
180-day period beginning on the effective date of any initial public offering or
any underwritten Demand Registration or any underwritten Piggyback Registration
in which Registrable Securities are included (except as part of such
underwritten registration or pursuant to registrations on Form S-4 or Form S-8
or any successor form), unless the underwriters managing the registered public
offering otherwise agree.

          (b)  The Company (i) shall not effect any public sale or distribution
of its equity securities, or any securities, options, or rights convertible into
or exchangeable or exercisable for such securities, during the seven days prior
to and during the 180-day period beginning on the effective date of any
underwritten Demand Registration or any underwritten Piggyback Registration
(except as part of such underwritten registration or pursuant to registrations
on Form S-8 or any successor form), unless the underwriters managing the
registered public offering otherwise agree, and (ii) to the extent not
inconsistent with applicable law, shall use its reasonable best efforts to cause
each holder of its equity securities, or any

                                      - 6 -
<Page>

securities convertible into or exchangeable or exercisable for equity
securities, purchased from the Company at any time after the date of this
Agreement (other than in a registered public offering) to agree not to effect
any public sale or distribution (including sales pursuant to Rule 144 of the
Securities Act) of any such securities during such period (except as part of
such underwritten registration, if otherwise permitted), unless the underwriters
managing the registered public offering otherwise agree.

          4.   REGISTRATION PROCEDURES. Whenever the holders of Registrable
Securities have requested that any Registrable Securities be registered pursuant
to this Agreement, the Company shall use its best efforts to effect the
registration and the sale of such Registrable Securities in accordance with the
intended method of disposition thereof, and pursuant thereto the Company shall
as expeditiously as possible:

          (a)  prepare and, within 75 days after the end of the period within
which requests for registration may be given to the Company, file with the
Securities and Exchange Commission a registration statement with respect to such
Registrable Securities and use its best efforts to cause such registration
statement to become effective (provided that, before filing a registration
statement or prospectus or any amendments or supplements thereto, the Company
shall furnish to the counsel selected by the holders of a majority of the
Registrable Securities covered by such registration statement copies of all such
documents proposed to be filed, which documents shall be subject to the review
and comment of such counsel);

          (b)  notify in writing each holder of Registrable Securities of the
effectiveness of each registration statement filed hereunder and prepare and
file with the Securities and Exchange Commission such amendments and supplements
to such registration statement and the prospectus used in connection therewith
as may be necessary to keep such registration statement effective for a period
of not less than 180 days (or, if such registration statement relates to an
underwritten offering, such longer period as in the opinion of counsel for the
underwriters a prospectus is required by law to be delivered in connection with
sales of Registrable Securities by an underwriter or dealer) and comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement during such period in
accordance with the intended methods of disposition by the sellers thereof set
forth in such registration statement;

          (c)  furnish to each seller of Registrable Securities such number of
copies of such registration statement, each amendment and supplement thereto,
the prospectus included in such registration statement (including each
preliminary prospectus), and such other documents as such seller may reasonably
request in order to facilitate the disposition of the Registrable Securities
owned by such seller;

          (d)  use its best efforts to register or qualify such Registrable
Securities under such other securities or blue sky laws of such jurisdictions as
any seller reasonably requests and do any and all other acts and things which
may be reasonably necessary or advisable to enable such seller of Registrable
Securities to consummate the disposition in such jurisdictions of the
Registrable Securities owned by such seller of Registrable Securities (provided
that the Company shall not be required to (i) qualify generally to do business
in any jurisdiction where it would not

                                      - 7 -
<Page>

otherwise be required to qualify but for this SECTION 4(d), (ii) subject itself
to taxation in any such jurisdiction, or (iii) consent to general service of
process in any such jurisdiction);

          (e)  promptly notify in writing each seller of such Registrable
Securities, at any time when a prospectus relating thereto is required to be
delivered under the Securities Act, of the happening of any event as a result of
which the prospectus included in such registration statement contains an untrue
statement of a material fact or omits any fact necessary to make the statements
therein not misleading in light of the circumstances under which they were made,
and, at the request of any such seller, the Company shall prepare and furnish to
each such seller a reasonable number of copies of a supplement or amendment to
such prospectus so that, as thereafter delivered to the purchasers of such
Registrable Securities, such prospectus shall not contain an untrue statement of
a material fact or omit to state any fact necessary to make the statements
therein not misleading in light of the circumstances under which they were made;

          (f)  use its best efforts to cause all such Registrable Securities to
be listed on each securities exchange on which similar securities issued by the
Company are then listed and, if not so listed, to be listed on the NASD
automated quotation system and, if listed on the NASD automated quotation
system, use its best efforts to secure designation of all such Registrable
Securities covered by such registration statement as a NASDAQ "national market
system security" within the meaning of Rule 11Aa2-1 of the Securities and
Exchange Commission or, failing that, to secure NASDAQ authorization for such
Registrable Securities;

          (g)  provide a transfer agent and registrar for all such Registrable
Securities not later than the effective date of such registration statement;

          (h)  enter into such customary agreements (including underwriting
agreements in customary form) and take all such other actions as the holders of
a majority of the Registrable Securities being sold or the underwriters, if any,
reasonably request in order to expedite or facilitate the disposition of
Registrable Securities (including effecting a stock split or a combination of
shares);

          (i)  make available for inspection by any underwriter participating in
any disposition pursuant to such registration statement, and any attorney,
accountant, or other agent retained by any seller of Registrable Securities or
any such underwriter, all financial and other records, pertinent corporate
documents and properties of the Company reasonably requested by such
underwriter, and cause the Company's officers, directors, employees, and
independent accountants to supply all information reasonably requested by any
seller of Registrable Securities, or any such underwriter, attorney, accountant,
or agent in connection with such registration statement and assist and, at the
request of any participating seller or underwriter, use reasonable best efforts
to cause such officers or directors to participate in presentations to
prospective purchasers;

          (j)  otherwise use its best efforts to comply with all applicable
rules and regulations of the Securities and Exchange Commission, and make
available to its security holders, as soon as reasonably practicable, an
earnings statement covering the period of at least twelve months beginning with
the first day of the Company's first full calendar quarter after the

                                      - 8 -
<Page>

effective date of the registration statement, which earnings statement shall
satisfy the provisions of Section 11(a) of the Securities Act and Rule 158
thereunder;

          (k)  in the event of the issuance of any stop order suspending the
effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any equity securities included in such registration statement for sale in any
jurisdiction, the Company shall use its best efforts promptly to obtain the
withdrawal of such order;

          (l)  use reasonable efforts to cause such Registrable Securities
covered by such registration statement to be registered with or approved by such
other governmental agencies or authorities as may be necessary to enable the
sellers thereof to consummate the disposition of such Registrable Securities;

          (m)  obtain one or more cold comfort letters, addressed to the
underwriters, if any, and dated the effective date of such registration
statement (and, if such registration includes an underwritten public offering,
dated the date of the closing under the underwriting agreement), from the
Company's independent public accountants in customary form and covering such
matters of the type customarily covered by cold comfort letters as the holders
of a majority of the Registrable Securities being sold in such registered
offering reasonably request (provided that such Registrable Securities
constitute at least 10% of the securities covered by such registration
statement). To the extent consistent with Statement on Auditing Standards No. 72
of the American Institute of Certified Public Accounts, the Company shall use
reasonable efforts to also have such cold comfort letters addressed to the
holders of the Registrable Securities being sold in such registered offering;
and

          (n)  provide a legal opinion of the Company's outside counsel, dated
the effective date of such registration statement (or, if such registration
includes an underwritten public offering, dated the date of the closing under
the underwriting agreement), with respect to the registration statement, each
amendment and supplement thereto, the prospectus included therein (including the
preliminary prospectus) and such other documents relating thereto (which counsel
and opinions shall be reasonably satisfactory to the managing underwriters, if
any, and the holders of a majority of the Registrable Securities being sold).
Such legal opinions shall be addressed to each selling holder and the
underwriters, if any, and shall be in customary form and covering such matters
of the type customarily covered by legal opinions of such nature.

          5.   REGISTRATION EXPENSES.

          (a)  Subject to SECTION 5(b) below, all expenses incident to or
incurred in connection with the Company's performance of or compliance with this
Agreement, including all registration and filing fees, fees and expenses of
compliance with securities or blue sky laws, printing expenses, travel expenses,
filing expenses, messenger and delivery expenses, fees and disbursements of
custodians, and fees and disbursements of counsel for the Company, and fees and
disbursements of all independent certified public accountants, underwriters
including, if necessary, a "qualified independent underwriter" within the
meaning of the rules of the National Association of Securities Dealers, Inc. (in
each case, excluding discounts and commissions), and other Persons retained by
the Company (all such expenses being herein called "REGISTRATION

                                      - 9 -
<Page>

EXPENSES"), shall be borne as provided in this Agreement, except that the
Company shall, in any event, pay its internal expenses (including all salaries
and expenses of its officers and employees performing legal or accounting
duties), the expense of any annual audit or quarterly review, the expense of any
liability insurance, and the expenses and fees for listing the securities to be
registered on each securities exchange on which similar securities issued by the
Company are then listed or on the NASD automated quotation system (or any
successor or similar system).

          (b)  In connection with each Demand Registration and each Piggyback
Registration, the Company shall reimburse the holders of Registrable Securities
included in such registration for the reasonable fees and disbursements of one
counsel chosen by the holders of a majority of the Registrable Securities
included in such registration.

          (c)  To the extent Registration Expenses are not required to be paid
by the Company, each holder of securities included in any registration hereunder
shall pay those Registration Expenses allocable to the registration of such
holder's securities so included, and any Registration Expenses not so allocable
shall be borne by all sellers of securities included in such registration in
proportion to the aggregate selling price of the securities to be so registered.

          6.   INDEMNIFICATION.

          (a)  The Company agrees to indemnify and hold harmless, to the fullest
extent permitted by law, each holder of Registrable Securities, its officers,
directors, agents, partners, members, and employees, and each Person who
controls such holder (within the meaning of the Securities Act) against all
losses, claims, damages, liabilities, and expenses (or actions or proceedings,
whether commenced or threatened, in respect thereof), whether joint and several
or several, together with reasonable costs and expenses (including reasonable
attorney's fees) to which any such indemnified party may become subject under
the Securities Act or otherwise (collectively, "LOSSES") caused by, resulting
from, arising out of, based upon, or relating to any untrue or alleged untrue
statement of material fact contained in (i) (A) any registration statement,
prospectus or preliminary prospectus, or any amendment thereof or supplement
thereto or (B) any application or other document or communication (in this
SECTION 6, collectively called an "application") executed by or on behalf of the
Company or based upon written information furnished by or on behalf of the
Company filed in any jurisdiction in order to qualify any securities covered by
such registration under the "blue sky" or securities laws thereof, (ii) any
omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading, or (iii) any violation
by the Company of any rule or regulation promulgated pursuant to any federal,
state or common law rule or regulation including, without limitation, the
Securities Act, applicable to the Company and relating to action or inaction
required of the Company in connection with any such registration, qualification
or compliance, and the Company will reimburse such holder and each such
director, officer, employee, partner, member and controlling Person for any
legal or any other expenses incurred by them in connection with investigating or
defending any such Losses; PROVIDED THAT the Company shall not be liable in any
such case to the extent that any such Losses result from, arise out of, are
based upon, or relate to an untrue statement or alleged untrue statement, or
omission or alleged omission, made in such registration statement, any such
prospectus, or preliminary prospectus or any amendment or supplement thereto, or
in any application, in reliance upon, and in conformity with, written
information prepared and furnished in writing to the Company by such holder

                                     - 10 -
<Page>

expressly for use therein or by such holder's failure to deliver a copy of the
registration statement or prospectus or any amendments or supplements thereto
after the Company has furnished such holder with a sufficient number of copies
of the same. In connection with an underwritten offering, the Company shall
indemnify such underwriters, their officers and directors, and each Person who
controls such underwriters (within the meaning of the Securities Act) to the
same extent as provided above with respect to the indemnification of the holders
of Registrable Securities.

          (b)  In connection with any registration statement in which a holder
of Registrable Securities is participating, each such holder will furnish to the
Company in writing such information and affidavits as the Company reasonably
requests for use in connection with any such registration statement or
prospectus and, to the fullest extent permitted by law, shall indemnify and hold
harmless the other holders of Registrable Securities and the Company, and their
respective officers, directors, agents, and employees, and each other Person who
controls the Company (within the meaning of the Securities Act) against any
Losses caused by, resulting from, arising out of, based upon, or relating to (i)
any untrue or alleged untrue statement of material fact contained in the
registration statement, prospectus or preliminary prospectus, or any amendment
thereof or supplement thereto or in any application, or (ii) any omission or
alleged omission of a material fact required to be stated therein or necessary
to make the statements therein not misleading, but only to the extent that such
untrue statement or omission is made in such registration statement, any such
prospectus or preliminary prospectus or any amendment or supplement thereto, or
in any application in reliance upon and in conformity with written information
prepared and furnished to the Company by such holder expressly for use therein,
and such holder will reimburse the Company and each such other indemnified party
for any legal or any other expenses incurred by them in connection with
investigating or defending any such Losses; PROVIDED THAT the obligation to
indemnify will be individual, not joint and several, for each holder and shall
be limited to the net amount of proceeds received by such holder from the sale
of Registrable Securities held by such holder pursuant to such registration
statement.

          (c)  Any Person entitled to indemnification hereunder will (i) give
prompt written notice to the indemnifying party of any claim with respect to
which it seeks indemnification (provided that the failure to give prompt notice
shall not impair any Person's right to indemnification hereunder to the extent
such failure has not prejudiced the indemnifying party) and (ii) unless in such
indemnified party's reasonable judgment a conflict of interest between such
indemnified and indemnifying parties may exist with respect to such claim,
permit such indemnifying party to assume the defense of such claim with counsel
reasonably satisfactory to the indemnified party. If such defense is assumed,
then the indemnifying party will not be subject to any liability for any
settlement made by the indemnified party without its consent (but such consent
will not be unreasonably withheld). An indemnifying party who is not entitled
to, or elects not to, assume the defense of a claim will not be obligated to pay
the fees and expenses of more than one counsel for all parties indemnified by
such indemnifying party with respect to such claim, unless in the reasonable
judgment of any indemnified party a conflict of interest may exist between such
indemnified party and any other of such indemnified parties with respect to such
claim.

          (d)  The indemnification provided for under this Agreement shall be in
addition to any other rights to indemnification or contribution which any
indemnified party may

                                     - 11 -
<Page>

have pursuant to law or contract, and will remain in full force and effect
regardless of any investigation made or omitted by or on behalf of the
indemnified party or any officer, director, or controlling Person of such
indemnified party and shall survive the transfer of securities.

          (e)  If the indemnification provided for in this SECTION 6 is
unavailable to or is insufficient to hold harmless an indemnified party under
the provisions above in respect to any Losses referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such Losses (i) in such proportion as is
appropriate to reflect the relative fault of the Company on the one hand and the
sellers of Registrable Securities and any other sellers participating in the
registration statement on the other hand or (ii) if the allocation provided by
clause (i) above is not permitted by applicable law, then in such proportion as
is appropriate to reflect not only the relative fault referred to in clause (i)
above but also the relative benefit of the Company on the one hand and of the
sellers of Registrable Securities and any other sellers participating in the
registration statement on the other in connection with the statement or
omissions which resulted in such Losses, as well as any other relevant equitable
considerations. The relative benefits received by the Company on the one hand
and the sellers of Registrable Securities and any other sellers participating in
the registration statement on the other shall be deemed to be in the same
proportion as the total net proceeds from the offering (before deducting
expenses) to the Company bear to the total net proceeds from the offering
(before deducting expenses) to the sellers of Registrable Securities and any
other sellers participating in the registration statement. The relative fault of
the Company on the one hand and of the sellers of Registrable Securities and any
other sellers participating in the registration statement on the other shall be
determined by reference to, among other things, whether the untrue or alleged
omission to state a material fact relates to information supplied by the Company
or by the sellers of Registrable Securities or other sellers participating in
the registration statement and the parties' relative intent, knowledge, access
to information, and opportunity to correct or prevent such statement or
omission.

          (f)  The Company and the sellers of Registrable Securities agree that
it would not be just and equitable if contribution pursuant to this SECTION 6
were determined by pro rata allocation (even if the sellers of Registrable
Securities were treated as one entity for such purpose) or by any other method
of allocation which does not take account of the equitable considerations
referred to in SECTION 6(e) above. The amount paid or payable by an indemnified
party as a result of the Losses referred to in SECTION 6(e) above shall be
deemed to include, subject to the limitations set forth above, any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this SECTION 6, no seller of Registrable Securities shall be
required to contribute pursuant to this SECTION 6 any amount in excess of the
sum of (i) any amounts paid pursuant to SECTION 6(b) above and (ii) the net
proceeds received by such seller from the sale of Registrable Securities covered
by the registration statement filed pursuant hereto. 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.

          7.   RULE 144 REPORTING. With a view to making available to the
holders of Registrable Securities benefits of certain rules and regulations of
the Securities and Exchange

                                     - 12 -
<Page>

Commission which may permit the sale of securities to the public without
registration, after the completion of any registration pursuant to SECTION 1 or
SECTION 2 above, the Company agrees to:

          (a)  use commercially reasonable efforts to make and keep public
information available, as those terms are understood and defined in Rule 144
under the Securities Act, or any successor provision thereto, at all times;

          (b)  use commercially reasonable efforts to file with the Securities
and Exchange Commission in a timely manner all reports and other documents
required of the Company under the Securities Act and the Exchange Act; and

          (c)  take any further reasonable action reasonably requested by a
Holder to enable such Holder to sell its Registrable Securities without
registration under Rule 144, under any successor provision, or any similar rule
or regulation promulgated by the SEC from time to time.

          8.   PARTICIPATION IN UNDERWRITTEN REGISTRATIONS.

          (a)  No Person may participate in any underwritten registration
hereunder unless such Person (i) agrees to sell such Person's securities on the
basis provided in any underwriting arrangements approved by the Person or
Persons entitled hereunder to approve such arrangements (including pursuant to
the terms of any over-allotment or "green shoe" option requested by the managing
underwriter(s), PROVIDED THAT no holder of Registrable Securities will be
required to sell more than the number of Registrable Securities that such holder
has requested the Company to include in any registration) and (ii) completes and
executes all questionnaires, powers of attorney, indemnities, underwriting
agreements, and other documents reasonably required under the terms of such
underwriting arrangements; PROVIDED THAT no holder of Registrable Securities
included in any underwritten registration shall be required to make any
representations or warranties to the Company or the underwriters (other than
representations and warranties regarding such holder and such holder's intended
method of distribution) or to undertake any indemnification obligations to the
Company or the underwriters with respect thereto, except as otherwise provided
in SECTION 6 hereof.

          (b)  Each Person that is participating in any registration hereunder
agrees that, upon receipt of any notice from the Company of the happening of any
event of the kind described in SECTION 4(e) above, such Person will immediately

          (c)  REMEDIES. Any Person having rights under any provision of this
Agreement shall be entitled to enforce such rights specifically to recover
damages caused by reason of any breach of any provision of this Agreement and to
exercise all other rights granted by law. The parties hereto agree and
acknowledge that money damages may not be an adequate remedy for any breach of

relief in order to enforce or prevent violation of the provisions of this
Agreement. Nothing contained in this Agreement shall be construed to confer upon
any Person who is not a signatory hereto any rights or benefits, whether as a
third-party beneficiary or otherwise.

          (d)  AMENDMENTS AND WAIVERS. Except as otherwise provided herein, no
modification, amendment, or waiver of any provision of this Agreement shall be

class or group materially and adversely affected thereby. No failure by any
party to insist upon the strict performance of any covenant, duty, agreement, or
condition of this Agreement or to exercise any right or remedy consequent upon a
breach thereof shall constitute a waiver of any such breach or any other
covenant, duty, agreement, or condition.

          (e)  SUCCESSORS AND ASSIGNS.

          (i)  All covenants and agreements in this Agreement by or on behalf of

successors and assigns of the parties hereto whether so expressed or not. In
addition, whether or not any express assignment has been made, the provisions of
this Agreement which are for the benefit of purchasers or holders of Registrable
Securities are also for the benefit of, and enforceable by, any subsequent
holder of Registrable Securities. Notwithstanding the foregoing, in order to
obtain the benefit of this Agreement, any subsequent holder of Registrable
Securities must execute a counterpart to this Agreement, thereby agreeing to be
bound the terms hereof.

          (ii) Without limiting the foregoing, the rights of the Warrant Holders
hereunder to cause the Company to register Warrant Holder Registrable Securities
in accordance with the terms hereof may be assigned by a Warrant Holder to a
permitted transferee or permitted assignee of any of its Warrant Holder
Registrable Securities; PROVIDED, HOWEVER, that the Company is given written
notice by the Warrant Holder at the time of or within a reasonable time after
the transfer, stating the name and address of the transferee or assignee and
identifying the securities with respect to which such registration rights are
being assigned. Nothing in this Section 11(e)(ii) shall be construed to limit or
otherwise affect any of the provisions of the Stockholders Agreement or
otherwise affect the rights of the holders of any other class of Registrable
Securities to transfer their Registrable Securities in accordance with the
Stockholders Agreement.

shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be prohibited

the extent of such prohibition or invalidity, without invalidating the remainder
of this Agreement.

          (g)  COUNTERPARTS. This Agreement may be executed simultaneously in
