            PROVISIONS RELATING TO EXECUTIVE STOCK

       (1)    (i) Upon the date of the Initial Closing, Executive will purchase,
and the Company will sell, 463,626 shares of Reserved Stock at a price of $0.10
per share. The Company will deliver to Executive the certificates representing
such shares of Reserved Stock, and Executive will deliver to the Company (A) by

cash in an amount equal to $464, (B) the Executive Note in the form of EXHIBIT A
attached hereto in an initial principal amount of $45,899 and (C) pursuant to
the Pledge Agreement (as defined below), certificates representing such shares
of Reserved Stock. The "EXECUTIVE NOTE" is that certain Revolving Promissory
Note dated as of the date of

<Page>

the Initial Closing pursuant to which the Company will loan to Executive, from
time to time, an amount not to exceed in the aggregate $154,221, so as to enable
Executive to purchase the Reserved Shares from the Company as provided for
herein. Executive's obligations under the Executive Note shall be secured by a
pledge of all of the shares of Reserved Stock purchased hereunder to the Company
and in connection therewith, Executive shall enter into a pledge agreement in
the form of EXHIBIT B attached hereto (the "PLEDGE AGREEMENT").

                     (ii)   In addition, upon the date of the Initial Closing,
       Executive will purchase, and the Company will sell, 652,995 shares of
       Carried Stock at a price of $0.10 per share. The Company will deliver to
       Executive copies of the certificates representing such Carried Stock, and
       Executive will deliver to the Company (A) by cashier's or certified check
       or wire transfer of immediately available funds, cash in an amount equal
       to $22,713 and (B) a Carry Note in the form of EXHIBIT C attached hereto
       in the principal amount of $42,587. The "CARRY NOTE" is one of those
       certain Carry Promissory Notes dated as of the date of the Initial
       Closing and the date of each Subsequent Closing (as defined in the
       Purchase Agreement) pursuant to which Executive purchases Executive Stock
       at which times the Company will loan to Executive, from time to time, an
       amount not to exceed in the aggregate $143,091, so as to enable Executive
       to purchase the Carried Shares from the Company as provided for herein.
       The principal amount of each Carry Note (determined in SECTION 1(b)(i)
       below) will be repaid, subject to earlier repayment in accordance with
       the terms of the Carry Note, by Executive in equal monthly installments
       in an amount determined by dividing the principal amount thereof by the
       number of remaining months before all of the Carried Stock is Vested
       Executive Stock (as determined pursuant to the vesting schedule in
       SECTION 3 hereof). All Carry Notes will be in the same form as the Carry
       Note attached as EXHIBIT C hereto except for the principal amount and the
       amount of the monthly payments, as determined in the immediately
       preceding sentence.

              (2)    Upon the purchase from time to time by GTCR and Co-Invest
of up to an additional 23,600,000 shares of Common Stock pursuant to SECTION
1B(b) of the Purchase Agreement, Executive will purchase and the Company will
sell up to an additional 1,541,068 shares of Carried Stock at a price of $0.10
per share and an additional 1,094,158 shares of Reserved Stock at a price of
$0.10 per share (the amounts set forth immediately above as adjusted from time
to time as a result of stock splits, stock dividends, recapitalizations and
similar events).

              (1)    The number of shares of Carried Stock to be sold by the
       Company and purchased by Executive at any time shall equal (i) 1,541,068
       shares of Carried Stock, MULTIPLIED BY (ii) a fraction (A) the numerator
       of which will be the number of shares of such Common Stock to be
       concurrently purchased by GTCR and Co-Invest and (B) the denominator of
       which will be 23,600,000 shares of Common Stock. The Company will deliver
       to Executive copies of the certificates representing such shares of
       Carried Stock purchased by Executive and Executive will purchase such
       shares of Carried Stock by (A) delivering to the Company, by wire
       transfer of immediately available funds, cash in an aggregate amount
       equal to the product of (1) the percentage of Carried Stock that is
       Vested Executive Stock (as determined pursuant to the vesting schedule in
       SECTION 3

                                       -2-
<Page>

       hereof) at the time of such purchase, MULTIPLIED by (2) the purchase
       price for such shares (such amount "THE CARRY CASH AMOUNT") and (B)
       delivering to the Company a Carry Note in the principal amount of the
       purchase price for such shares MINUS the Carry Cash Amount.

              (2)    The number of shares of Reserved Stock to be sold by the
       Company and purchased by Executive at any time shall equal (i) 1,094,158
       shares of Reserved Stock, MULTIPLIED BY (ii) a fraction (A) the numerator
       of which will be the number of shares of such Common Stock to be
       concurrently purchased by GTCR and Co-Invest and (B) the denominator of
       which will be 23,600,000 shares of Common Stock. The Company will deliver
       to Executive copies of the certificates representing such shares of
       Reserved Stock purchased by Executive, and Executive will purchase such
       shares of Reserved Stock by (A) delivering to the Company, by wire
       transfer of immediately available funds, cash in an aggregate amount
       equal to the par value per share of such Reserved Stock multiplied by the
       number of shares of Reserved Stock so purchased by Executive and (B)
       increasing the principal amount outstanding under the Executive Note to
       reflect the aggregate amount of the price per share of such Reserved
       Stock, MINUS the par value per such share, MULTIPLIED BY the number of
       shares of such Reserved Stock so purchased by Executive.

              (3)    Within 30 days after the date of any purchase of Executive
Stock, Executive will make an effective election with the Internal Revenue
Service under Section 83(b) of the Internal Revenue Code of 1986, as amended
(the "INTERNAL REVENUE CODE") and the regulations promulgated thereunder in the
form of EXHIBIT D attached hereto.

              (4)    Notwithstanding anything herein to the contrary, until the
occurrence of a Sale of the Company, all certificates evidencing shares of
Executive Stock shall be held by the Company for the benefit of Executive and
the other holder(s) of Executive Stock. Upon the occurrence of a Sale of the
Company, the Company will return the certificates for the Executive Stock to the
record holders thereof. Upon the occurrence of a Public Offering, the Company
will return to the record holders thereof certificates representing the shares
of Executive Stock which are Vested Executive Stock.

              (5)    In connection with the purchase and sale of the Executive
Stock, Executive represents and warrants to the Company that:

              (1)    The Executive Stock to be acquired by Executive pursuant to
       this Agreement will be acquired for Executive's own account and not with
       a view to, or intention of, distribution thereof in violation of the
       Securities Act, or any applicable state securities laws, and the
       Executive Stock will not be disposed of in contravention of the
       Securities Act or any applicable state securities laws.

              (2)    Executive is an executive officer of the Company and the
       Employer, is sophisticated in financial matters and is able to evaluate
       the risks and benefits of the investment in the Executive Stock.

                                       -3-
<Page>

              (3)    Executive is able to bear the economic risk of his
       investment in the Executive Stock for an indefinite period of time
       because the Executive Stock has not been registered under the Securities
       Act and, therefore, cannot be sold unless subsequently registered under
       the Securities Act or an exemption from such registration is available.

              (4)    Executive has had an opportunity to ask questions and
       receive answers concerning the terms and conditions of the offering of
       Executive Stock and has had full access to such other information
       concerning the Company as he has requested.

              (5)    This Agreement constitutes the legal, valid and binding
       obligation of Executive, enforceable in accordance with its terms, except
       to the extent that enforceability may be limited by bankruptcy,
       insolvency or other similar laws affecting creditors' rights generally,
       and the execution, delivery and performance of this Agreement by
       Executive does not and will not conflict with, violate or cause a breach
       of any agreement, contract or instrument to which Executive is a party or
       any judgment, order or decree to which Executive is subject.

              (6)    Executive is neither a party to, nor bound by, any other
       employment agreement, consulting agreement, noncompete agreement,
       non-solicitation agreement or confidentiality agreement (other than that
       certain Senior Management Agreement dated July 31, 1998, as amended on
       July 14, 1999, July 31, 1999 and June 20, 2000 among AppNet, Inc., a
       Delaware corporation, Commerce One, Inc., a Delaware corporation, and
       Executive).

              (7)    Executive has not and will not take any action that will
       conflict with, violate or cause a breach of any noncompete,
       nonsolicitation or confidentiality agreement to which Executive is a
       party or by which Executive is bound.

              (8)    Executive is a resident of the District of Columbia.

              (6)    As an inducement to the Company to issue the Executive
Stock to Executive, and as a condition thereto, Executive acknowledges and
agrees that neither the issuance of the Executive Stock to Executive nor any
provision contained herein shall entitle Executive to remain in the employment
of the Company and its Subsidiaries (including the Employer) or affect the right
of the Company and its Subsidiaries (including the Employer) to terminate
Executive's employment at any time for any reason.

              (7)    Concurrently with the execution of this Agreement,
Executive shall execute in blank ten stock transfer powers in the form of
EXHIBIT E attached hereto (the "STOCK POWERS") with respect to the Executive
Stock and shall deliver such Stock Powers to the Company. The Stock Powers shall
authorize the Company to assign, transfer and deliver the shares of Executive
Stock to the appropriate acquiror thereof pursuant to SECTION 4 below or Section
6 of the Stockholders Agreement and under no other circumstances.

                                       -4-
<Page>

              2.     REPURCHASE OF RESERVED STOCK

              (1)    From time to time, the Company may issue or sell Common
Stock (or rights to acquire Common Stock) to the Company's or its Subsidiaries'
employees (an "EMPLOYEE ISSUANCE"). If the Company elects to make an Employee
Issuance, the Company shall have the right to purchase from Executive, and
Executive shall sell to the Company, the number of shares of Reserved Stock to
be issued in connection with such Employee Issuance pursuant to this SECTION 2.
In addition, in the event Executive ceases to be employed by the Employer for
any reason (the "SEPARATION"), the Company shall have the right to purchase from
Executive, and Executive shall sell to the Company, all of the Executive's
shares of Reserved Stock pursuant to this SECTION 2.

              (2)    In order to purchase Reserved Stock, the Company shall
provide written notice to Executive (the "RESERVED STOCK NOTICE") either (i)
providing notice of the Employee Issuance and the number of shares of Reserved
Stock to be repurchased in connection therewith or (ii) providing notice that
all of the shares of Reserved Stock held by the Executive will be repurchased
due to a Separation. The sale of the Reserved Stock shall occur five days after
the Company sends the Reserved Stock Notice or, if later, immediately prior to
the consummation of the Employee Issuance. At the closing of the sale and
purchase of the Reserved Stock, the Company shall, first, pay by check or wire
transfer the par value of such shares and, second, decrease the principal amount
outstanding under the Executive Note by the aggregate repurchase price for the
Reserved Stock being repurchased (less the aggregate par value of such shares),
and Executive shall deliver to the Company certificates evidencing the Reserved
Stock to be sold to the Company. In connection with any repurchase hereunder,
the Company will be entitled to receive customary representations and warranties
regarding such repurchase and to require that all sellers' signatures be
guaranteed.

              (3)    The repurchase price for all shares of Reserved Stock shall
be the Original Cost thereof plus the pro rata portion of any interest, fees and
expenses paid or payable pursuant to the Executive Note with respect to such
repurchased shares of Reserved Stock. The Company's right to repurchase Reserved
Stock shall expire upon the first to occur of (i) a Liquidity Event and (ii) a
Public Offering.

              3.     VESTING OF EXECUTIVE STOCK.

              (1)    The Executive Stock shall be subject to vesting in the
manner specified in this SECTION 3. The Carried Stock and, upon the consummation
of a Public Offering and prior to a Liquidity Event, the Reserved Stock will
become vested in accordance with the following schedule, if as of each such date
Executive is still employed by the Company or any of its Subsidiaries (including
the Employer):

                     (i)  34.7826% as of the date of the Initial Closing; and

                     (ii) 1.8116% on the last day of each full calendar month
                     beginning with the first full calendar month following the
                     date of the Initial Closing.

                                       -5-
<Page>

              (2)    Shares of (i) Carried Stock(x) that have become vested in
accordance with the foregoing schedule or (y) immediately upon a Sale of the
Company, (ii) upon the consummation of a Public Offering and prior to a
Liquidity Event, Reserved Stock that have become vested in accordance with the
foregoing schedule, (iii) Reserved Stock upon the consummation of a Liquidity
Event and (iv) Executive Stock upon a Section 7 Breach shall be vested Executive
Stock and are referred to herein as "VESTED EXECUTIVE STOCK" and shares of (i)
Carried Stock that have not become vested in accordance with the foregoing
schedule, and (ii) upon the consummation of a Public Offering and prior to a
Liquidity Event, Reserved Stock that have not become vested in accordance with
the foregoing schedule are referred to herein as "UNVESTED EXECUTIVE STOCK."

              (3)    Notwithstanding any other provision of this Agreement, at
any time the exemption pursuant to Section 280G(b)(5)(A) of the Internal Revenue
Code is available, (i) Executive Stock that becomes Vested Executive Stock upon
a "change in ownership or control" (as such phrase is defined in Section 280G of
the Internal Revenue Code and the regulations promulgated thereunder ("SECTION
280G")) (a "CHANGE OF CONTROL") shall not become Vested Executive Stock by
reason of a Change of Control and (ii) payments made pursuant to SECTION 7(d) of
this Agreement upon a Change of Control shall not be made, unless those Persons
who own immediately prior to a Change of Control more than 75% of the voting
power of all the outstanding interests of the Company and the Employer vote to
approve such vesting (the "APPROVALS").

              (4)    The Company and the Employer (i) shall take all steps
reasonably requested by Executive to obtain the Approvals, 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 of the Company and the Employer approve all
proposals related thereto and take such other reasonable steps as Executive
requests, (ii) shall not report or withhold any excise tax pursuant to Section
4999 of the Internal Revenue Code with respect to any payments (including
without limitation accelerated vesting) for which the Approvals have been
obtained and (iii) shall use reasonable best efforts to qualify all payments as
not subject to penalties imposed under Sections 280G and 4999 of the Code.
Notwithstanding the preceding, the obligations of the Company and the Employer
set forth in clause (ii) of the preceding sentence are subject to the condition
that, at the request of the Company at least 15 business days prior to the
anticipated withholding, the Executive shall have provided a reasoned opinion
from Fried Frank Shriver & Jacobson or other counsel reasonably acceptable to
the Company or a nationally recognized accounting firm concluding that there is
a reasonable basis for such reporting position.

              (5)    Executive agrees to indemnify the Company and the Employer,
their respective Subsidiaries and their Affiliates (other than Executive)
(collectively, the "INDEMNIFIED PARTIES"), and save and hold each of them
harmless against and pay on behalf of or reimburse such Indemnified Parties as
and when incurred for any withholding tax, and any penalty and interest thereon
(including in the event that the Executive does not elect to assume the defense
of the Indemnified Matter (as defined below), reasonable attorneys' fees and
expenses and all amounts paid in investigation, defense or settlement of any of
the foregoing) relating to any excise tax owed by Executive pursuant to Section
4999 of the Internal Revenue Code which any

                                       -6-
<Page>

such Indemnified Party may suffer, sustain or become subject to in connection
with any withholding obligations of the Indemnified Parties; PROVIDED, HOWEVER,
that the indemnity set forth in this paragraph shall expire immediately upon
payment by the Executive (i) to the Internal Revenue Service of any excise tax
with respect to the Executive's compensation pursuant to Section 4999 of the
Internal Revenue Code and (ii) to the applicable Indemnified Parties to
reimburse them for any interest and/or penalties attributable to their failure
to withhold such excise tax.

              The Indemnified Parties shall give the Executive written notice (a
"NOTICE") of any claim or other matter as to which indemnification will be
sought under this paragraph (an "INDEMNIFIED MATTER") as promptly as practicable
after the Indemnified Parties become aware of the Indemnified Matter and shall
thereafter keep the Executive reasonably informed with respect thereto. The
Executive may, by written notice to the Indemnified Parties within 30 days after
receipt of such Notice, assume the defense of such Indemnified Matter with Fried
Frank Harris Shriver & Jacobson or other counsel reasonably acceptable to the
Indemnified Parties, at the Executive's expense, and the Indemnified Parties
shall reasonably cooperate with the Executive in any such action and the
Executive will be responsible for the reasonable expenses thereof. If the
Executive assumes such defense, he shall consult with the Indemnified Parties
from time to time with respect to such Indemnified Matter and shall not settle
any claims relating to such Indemnified Matter without providing for payment by
the Executive of such settlement to the extent not previously paid. As long as
the Executive is contesting any such Indemnified Matter in good faith and on a
timely basis, the Indemnified Parties shall not pay or settle any claims
relating to such Indemnified Matter. Notwithstanding the assumption by the
Executive of such defense, the Indemnified Parties may, but shall have no duty
to, join in such defense and employ counsel at their own expense provided that
Executive shall control such defense.

              If the Indemnified Parties or the Executive pay any withholding
tax, interest and/or penalty with respect to an Indemnified Matter and the
Indemnified Parties subsequently receive a refund, credit or return (or would
have received a refund, credit or return, but for the existence of a claim for
taxes not indemnified against hereunder, a "DEEMED REFUND"), in whole or in
part, of such taxes, interest and/or penalties the Indemnified Parties shall
promptly pay to the Executive in the amount of such Deemed Refund or such
refunded, credited or returned taxes, plus interest received with respect to
such Deemed Refund or such refunded, credited or returned taxes, interest and/or
penalties (or in the case of a Deemed Refund, interest calculated at the rate
paid by the Internal Revenue Service on overpayments of income tax from and
including the date of the payment of such indemnified amount to the Indemnified
Parties by the Executive to but excluding the date of payment of such Deemed
Refund or such refunded, credited or returned taxes, interest and/or penalties
to the Executive by the Indemnified Parties).

              (6)    Subject to the restrictions contained in SECTION 5(b)(ii)
hereof, promptly following the occurrence of Public Offering, the Company shall
use all commercially reasonable efforts to file a Form S-8/S-3 under the
Securities Act in order to enable the Executive Stock to be registered under the
Securities Act and to be resold from time to time by Executive; provided that
after the fifth anniversary of the date of the Initial Closing, the Executive
may only sell Executive Stock under such Form S-8/S-3 up to a maximum number of
shares of Executive Stock equal to the greater of (x) in any three month period,
an amount equal to the greater of the

                                       -7-
<Page>

amount specified in Rule 144(e)(1) (without regard to any other restriction
under Rule 144) and (y) an amount that could be sold by Executive pursuant to
SECTION 5(b) of this Agreement (without regard to SECTION 5(c) of this
Agreement).

              4.     REPURCHASE OPTION.

              (1)    In the event of the Separation, the Unvested Executive
Stock (whether held by Executive or one or more of Executive's permitted
transferees, other than the Company and the Investors) will be subject to
repurchase, in each case at the option of the Company and the Investors pursuant
to the terms and conditions set forth in this SECTION 4 (the "REPURCHASE
OPTION").

              (2)    In the event of a Separation, the purchase price for each
share of Unvested Executive Stock will be the lower of (A) Executive's Original
Cost for such share and (B) the Fair Market Value for such share.

              (3)    The Company may elect to purchase all or any portion of the
Unvested Executive Stock by delivering written notice (the "REPURCHASE NOTICE")
to the holder or holders of the Unvested Executive Stock within 90 days after
the Separation. The Repurchase Notice will set forth the number of shares of
Unvested Executive Stock to be acquired from each holder, the aggregate
consideration to be paid for such shares and the time and place for the closing
of the transaction. The number of shares to be repurchased by the Company shall
first be satisfied to the extent possible from the shares of Unvested Executive
Stock held by Executive at the time of delivery of the Repurchase Notice. If the
number of shares of Unvested Executive Stock then held by Executive is less than
the total number of shares of Unvested Executive Stock which the Company has
elected to purchase, the Company shall purchase the remaining shares elected to
be purchased from the other holder(s) of Unvested Executive Stock under this
Agreement, pro rata according to the number of shares of Unvested Executive
Stock held by such other holder(s) at the time of delivery of such Repurchase
Notice (determined as nearly as practicable to the nearest share).

              (4)    If for any reason the Company does not elect to purchase
all of the Unvested Executive Stock pursuant to the Repurchase Option, the
Investors shall be entitled to exercise the Repurchase Option for all or any
portion of the shares of Unvested Executive Stock the Company has not elected to
purchase (the "AVAILABLE SHARES"). As soon as practicable after the Company has
determined that there will be Available Shares, but in any event within 120 days
after the Separation, the Company shall give written notice (the "OPTION
NOTICE") to the Investors setting forth the number of Available Shares and the
purchase price for the Available Shares. The Investors may elect to purchase any
or all of the Available Shares by giving written notice to the Company within
one month after the Option Notice has been given by the Company. If the
Investors elect to purchase an aggregate number of shares greater than the
number of Available Shares, the Available Shares shall be allocated among each
Investor so electing based upon the number of shares of Common Stock owned by
such Investor on a fully diluted basis. As soon as practicable, and in any event
within ten days, after the expiration of the one-month period set forth above,
the Company shall notify each holder of Unvested Executive Stock as to the
number of shares being purchased from such holder by the Investors (the

                                       -8-
<Page>

"SUPPLEMENTAL REPURCHASE NOTICE"). At the time the Company delivers the
Supplemental Repurchase Notice to the holder(s) of Unvested Executive Stock, the
Company shall also deliver written notice to each electing Investor setting
forth the number of shares such Investor is entitled to purchase, the aggregate
purchase price and the time and place of the closing of the transaction.
Notwithstanding the foregoing, the Investors shall not exercise their Repurchase
Option pursuant to this Section 4(d) if the Company has sufficient assets to
exercise fully its Repurchase Option but has not exercised such right as a
result of applicable restrictions contained in the Delaware General Corporation
Law or in the Company's and its Subsidiaries' debt or equity financing
agreements.

              (5)    The closing of the purchase of the Unvested Executive Stock
pursuant to the Repurchase Option shall take place on the date designated by the
Company in the Repurchase Notice or Supplemental Repurchase Notice, which date
shall not be more than one month nor less than five days after the delivery of
the later of either such notice to be delivered. The Company will pay for the
Unvested Executive Stock to be purchased by it pursuant to the Repurchase Option
by first offsetting amounts outstanding under any bona fide debts owed by
Executive to the Company (including, without limitation, in the case of Unvested
Executive Stock which is Reserved Stock, by reducing the principal amount under
the Executive Note, and in the case of Unvested Executive Stock which is Carried
Stock, by reducing the principal amount under the Carry Notes) and will pay the
remainder of the purchase price by a check or wire transfer of funds in the
aggregate amount of the purchase price for such shares. Each Investor will pay
for the Unvested Executive Stock purchased by it by a check or wire transfer of
funds. The Company and the Investors will be entitled to receive customary
representations and warranties from the sellers regarding such sale and to
require that all sellers' signatures be guaranteed.

              (6)    Notwithstanding anything to the contrary contained in this
Agreement, all repurchases of Unvested Executive Stock by the Company shall be
subject to applicable restrictions contained in the Delaware General Corporation
Law and in the Company's and its Subsidiaries' debt and equity financing
agreements. If any such restrictions prohibit the repurchase of Unvested
Executive Stock hereunder which the Company is otherwise entitled or required to
make, the Company may make such repurchases within 15 days of being permitted to
do so under such restrictions.

              (7)    The provisions of this SECTION 4 shall terminate
immediately prior to consummation of a Liquidity Event (provided that the
Liquidity Event is consummated).

              5.     RESTRICTIONS ON TRANSFER OF EXECUTIVE STOCK.

              (1)    TRANSFER OF EXECUTIVE STOCK. Prior to the earlier to occur
of (i) a Liquidity Event and (ii) a Public Offering, the Executive shall not
Transfer any interest in any shares of Reserved Stock, except pursuant to (i)
the provisions of SECTION 2 hereof and (iii) an Approved Sale (as defined in
Section 6 of the Stockholders Agreement). The holders of Carried Stock and,
after the earlier to occur of (i) a Liquidity Event and (ii) a Public Offering,
the Reserved Stock shall not Transfer any interest in any shares of such
Executive Stock, except pursuant to (i) the provisions of SECTION 4 hereof, (ii)
the provisions of Section 4 of the Stockholders Agreement (a

                                       -9-
<Page>

"PARTICIPATING SALE"), (iii) an Approved Sale (as defined in Section 6 of the
Stockholders Agreement) or (iv) the provisions of SECTION 5(b) below.

              (2)    CERTAIN PERMITTED TRANSFERS. The restrictions in this
SECTION 5 will not apply with respect to any Transfer of Executive Stock (other
than Reserved Stock prior to the earlier to occur of (i) a Liquidity Event and
(ii) a Public Offering) made (i) pursuant to applicable laws of descent and
distribution or to such Person's legal guardian in the case of any mental
incapacity or among such Person's Family Group, (ii) of Vested Executive Stock
at such time as the Investors sell shares of Common Stock in a Public Sale, but
in the case of this clause (ii) only an amount of shares (the "TRANSFER AMOUNT")
equal to the lesser of (A) the number of shares of Vested Executive Stock owned
by Executive and (B) the number of shares of Executive Stock owned by Executive,
multiplied by a fraction (the "TRANSFER FRACTION"), the numerator of which is
the number of shares of Common Stock sold by the Investors and their Affiliates
in such Public Sale and the denominator of which is the total number of shares
of Common Stock held by the Investors and their Affiliates prior to the Public
Sale; PROVIDED THAT, if at the time of a Public Sale of shares by the Investors,
Executive chooses not to Transfer the Transfer Amount, Executive shall retain
the right to Transfer an amount of Executive Stock at a future date equal to the
lesser of (x) the number of shares of Vested Executive Stock owned by Executive
at such future date and (y) the number of shares of Executive Stock owned by
Executive at such future date multiplied by the Transfer Fraction; PROVIDED
FURTHER that any in-kind distributions of Common Stock by the Investors to their
limited partners shall be deemed to be a Public Sale for purposes of this
SECTION 5(b)(ii) or (iii) of Vested Executive Stock at any time the Common Stock
held by the Investors or their Affiliates is included on a resale registration
statement that is not part of an underwritten offering (the "Resale Shelf"), but
in the case of this clause (iii) only an amount equal to the lesser of (A) the
number of shares of Vested Executive Stock owned by Executive and (B) the number
of shares of Executive Stock owned by Executive, multiplied by a fraction, the
numerator of which is the total number of shares of Common Stock included by the
Investors and their Affiliates on the Resale Shelf and the denominator of which
is the total number of shares of Common Stock held by the Investors and their
Affiliates prior to the effectiveness of the Resale Shelf. The restrictions
contained in this SECTION 5 will continue to be applicable to the Executive
Stock after any Transfer of the type referred to in clause (i) above and the
transferees of such Executive Stock will agree in writing to be bound by the
provisions of this Agreement. Any transferee of Executive Stock pursuant to a
transfer in accordance with the provisions of this SECTION 5(b) is herein
referred to as a "PERMITTED TRANSFEREE." Upon the transfer of Executive Stock
pursuant to this SECTION 5(b), the transferring Executive Stockholder will
deliver a written notice (a "TRANSFER NOTICE") to the Company. In the case of a
Transfer pursuant to clause (i) hereof, the Transfer Notice will disclose in
reasonable detail the identity of the Permitted Transferee(s).

              (3)    TERMINATION OF RESTRICTIONS. The restrictions set forth in
this SECTION 5 will continue with respect to each share of Executive Stock until
the earlier of (i) the date on which such share of Executive Stock has been
transferred in a Public Sale permitted by this SECTION 5,(ii) the consummation
of an Approved Sale, (iii) the consummation of a Liquidity Event and (iv) the
fifth anniversary of the date of the Initial Closing.

              6.     ADDITIONAL RESTRICTIONS ON TRANSFER OF EXECUTIVE STOCK.

                                      -10-
<Page>

              (1)    LEGEND. The certificates representing the Executive Stock
will bear a legend in substantially the following form:

       "THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ORIGINALLY ISSUED AS
       OF [DATE OF ISSUANCE], HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
       OF 1933, AS AMENDED (THE "ACT"), AND MAY NOT BE SOLD OR TRANSFERRED IN
       THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR AN
       EXEMPTION FROM REGISTRATION THEREUNDER. THE SECURITIES REPRESENTED BY
       THIS CERTIFICATE ARE ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER,
       CERTAIN REPURCHASE OPTIONS AND CERTAIN OTHER AGREEMENTS SET FORTH IN A
       SENIOR MANAGEMENT AGREEMENT BETWEEN THE COMPANY AND AN EXECUTIVE OF THE
       COMPANY DATED AS OF SEPTEMBER __, 2001. A COPY OF SUCH AGREEMENT MAY BE
       OBTAINED BY THE HOLDER HEREOF AT THE COMPANY'S PRINCIPAL PLACE OF
       BUSINESS WITHOUT CHARGE."

              (2)    OPINION OF COUNSEL. No holder of Executive Stock may sell,
transfer or dispose of any Executive Stock (except pursuant to an effective
registration statement under the Securities Act or pursuant to Section 5(b)(i)
hereof) without first delivering to the Company a written notice describing in
reasonable detail the proposed transfer, together with an opinion of counsel
(reasonably acceptable in form and substance to the Company) that neither
registration nor qualification under the Securities Act and applicable state
securities laws is required in connection with such transfer. In addition, if
the holder of the Executive Stock delivers to the Company an opinion of counsel
that no subsequent transfer of such Executive Stock shall require registration
under the Securities Act, the Company shall promptly upon such contemplated
transfer deliver new certificates for such Executive Stock which do not bear the
Securities Act portion of the legend set forth in SECTION 6(a). If the Company
is not required to deliver new certificates for such Executive Stock not bearing
such legend, the holder thereof shall not transfer the same until the
prospective transferee has confirmed to the Company in writing its agreement to
be bound by the conditions contained in this SECTION 6.

                        PROVISIONS RELATING TO EMPLOYMENT

              7.     EMPLOYMENT. The Company and the Employer agree to employ
Executive and Executive accepts such employment for the period beginning as of
the date of the Initial Closing and ending upon his separation pursuant to
SECTION 7(d) hereof (the "EMPLOYMENT PERIOD").

              (1)    POSITION AND DUTIES.

              (1)    During the Employment Period, Executive shall serve as the
       Chief Financial Officer of the Company and the Employer and shall have
       the normal duties,

                                      -11-
<Page>

       responsibilities and authority of the Chief Financial Officer, subject to
       the power of the Employer Board and the Company Board to expand or limit
       such duties, responsibilities and authority and to override actions of
       the Chief Financial Officer.

              (2)    Executive shall report to the Chief Executive Officer, and
       Executive shall devote his best efforts and his full business time and
       attention to the business and affairs of the Company and its
       Subsidiaries. Notwithstanding the foregoing, from and after the date of
       the Initial Closing, Executive may (1) serve on corporate, trade group,
       civil or charitable boards or committees, (2) deliver lectures, fulfill
       speaking engagements or teach at educational institutions or programs,
       (3) serve as a personal representative or trustee, (4) manage his
       personal, financial and legal affairs and (5) invest personally in any
       business in a private capacity where no actual conflict of interest
       exists between such investment and the business of the Employer, so long
       as the foregoing activities do not interfere with Executive's performance
       of his obligations hereunder. The Employer hereby agrees that any
       earnings of Executive in connection with the permissible activities
       described in the preceding sentence may be retained by Executive.

              (2)    SALARY AND BENEFITS. Commencing upon the date of the
Initial Closing and until the date six months from the date of the Initial
Closing the Employer will pay Executive a base salary (the "ANNUAL BASE SALARY")
of $200,000 per annum and thereafter during the remainder of the Employment
Period, the Employer will pay Executive an Annual Base Salary of $250,000, in
each case subject to any increase as determined by the Company Board based upon
the Employer's achievements of budgetary and other objectives set by the Company
Board. Executive's Annual Base Salary for any partial year will be prorated
based upon the number of days elapsed in such year. In addition, during the
Employment Period, Executive will be entitled to such other benefits approved by
the Company Board and made available to the Employer's senior management. The
Company and the Employer will pay or reimburse Executive for reasonable travel,
entertainment or other expenses incurred by Executive in the furtherance of or
in connection with the performance of Executive's duties hereunder in accordance
with the Company's or the Employer's established policies, as applicable.

              (3)    BONUS. Commencing at such time as determined by the Company
Board, Executive shall be eligible to receive a bonus of up to fifty (50%) of
the Annual Base Salary based upon the Employer's achievement of budgetary and
other objectives set forth by the Company Board.

              (4)    SEPARATION. The Employment Period will continue until
Executive's resignation, Disability or death or until the Company Board decides
to terminate Executive's employment with or without Cause. If, after the earlier
to occur of (A) a Sale of the Company or (B) a Base Acquisition, (i) Executive's
employment is terminated by the Employer without Cause or (ii) Executive resigns
with Good Reason, during the one-year period commencing on the date of
termination (the "SEVERANCE PERIOD") the Company shall pay to Executive (i) an
aggregate amount equal to his Annual Base Salary payable, at the Company Board's
discretion, either in a lump sum amount within 10 days of the date of
termination or in equal installments on the Company's regular salary payment
dates, (ii) any unpaid bonus awarded under Section 7(c) hereof with respect to
all prior years in one lump sum, (iii) benefits under group health and life

                                      -12-
<Page>

insurance plans in which Executive participated prior to termination through the
Severance Period, (v) all previously earned, accrued, and unpaid benefits from
the Company, the Employer and their respective employee benefit plans,
including, without limitation, any such benefits under the Company's or the
Employer's pension, disability, and life insurance plans, policies, and
programs, (vi) expenses reimbursable under Section 7(b) hereof and (vii) all
previously earned, accrued, and unpaid compensation and benefits, if any, under
Section 7(b) hereof.

Executive shall not be required to mitigate the amounts payable pursuant to this
Section 7(d) by seeking other employment or otherwise, and no such payment shall
be offset or reduced by the amount of any compensation or benefits provided to
Executive in any subsequent employment.

              8.     CONFIDENTIAL INFORMATION.

              (1)    OBLIGATION TO MAINTAIN CONFIDENTIALITY. Executive
acknowledges that the information, observations and data obtained by him during
the course of his performance under this Agreement concerning the business and
affairs of the Company and its Affiliates are the property of the Company,
including, without limitation, information concerning acquisition opportunities
in or reasonably related to the Company's business or industry of which
Executive becomes aware during the Employment Period ("CONFIDENTIAL
INFORMATION"). Therefore, Executive agrees that he will not disclose to any
unauthorized person or use for his own account any of such Confidential
Information without the Company Board's written consent. The term "Confidential
Information" does not include information, observations or data which (i) is or
becomes generally available to the public or is generally known or is generally
disclosed by practice within the Company's and its Subsidiaries' industry other
than as a result of a disclosure by Executive in violation of this Agreement or
(ii) was within the Executive's possession prior to its being obtained by him in
the course of his performance under this Agreement. Executive agrees to deliver
to the Employer at a Separation, or at any other time the Employer may request
in writing, all memoranda, notes, plans, records, reports and other documents
(and copies thereof) relating to the business of the Company and its Affiliates
(including, without limitation, all acquisition prospects, lists and contact
information) which he may then possess or have under his control.

              (2)    In the event that Executive is requested or required (by
deposition, interrogatories, requests for information or documents in legal
proceedings, subpoenas, civil investigative demand, governmental or regulatory
process or similar process), in connection with any proceeding, to disclose any
information otherwise prohibited from disclosure under this Agreement, Executive
will give the Company prompt written notice of such request or requirement so
that the Company may seek an appropriate protective order or other remedy and/or
waive compliance with the provisions of this Agreement, and Executive will
cooperate with the Company, at the Company's expense, to obtain such protective
order. In the event that such protective order or other remedy is not obtained
or the Company waives compliance with the relevant provisions of this Agreement,
Executive will furnish only that portion of the information which is legally
required to be disclosed. It is further agreed that, if in the absence of a
protective order Executive is nonetheless required by law, regulation or
regulatory process to disclose such information, Executive may make such
disclosure without liability hereunder, provided that Executive gives the
Company notice of the information to be disclosed as far in

                                      -13-
<Page>

advance of its disclosure as is practicable and, upon the Company's request,
Executive uses reasonable best efforts, at the Company's expense, to obtain
assurances that confidential treatment will be accorded to such information and,
provided further, that such disclosure was not caused by and did not result from
a previous disclosure by Executive not permitted hereunder.

              (3)    OWNERSHIP OF PROPERTY. Executive acknowledges that all
inventions, innovations, improvements, developments, methods, processes,
programs, designs, analyses, drawings, reports, and all similar or related
information (whether or not patentable) that relate to the Company's or any of
its Subsidiaries' or Affiliates' actual or reasonably anticipated business,
research and development, or existing or future products or services and that
are conceived, developed, contributed to, made, or reduced to practice by
Executive (either solely or jointly with others) while employed by the Company
or any of its Subsidiaries or Affiliates ("WORK PRODUCT") belong to the Company
or such Subsidiary or such Affiliate and Executive hereby assigns, and agrees to
assign, all of the above Work Product to the Company or to such Subsidiary or
such Affiliate. Any copyrightable work prepared in whole or in part by Executive
in the course of his work for any of the foregoing entities shall be deemed a
"work made for hire" under the copyright laws, and the Company or such
Subsidiary or such Affiliate shall own all rights therein. To the extent that
any such copyrightable work is not a "work made for hire," Executive hereby
assigns and agrees to assign to the Company or such Subsidiary or such Affiliate
all right, title, and interest, including without limitation, copyright in and
to such copyrightable work. Executive shall promptly disclose such Work Product
and copyrightable work to the Company Board and, at the request and cost of the
Company or its Subsidiaries, perform all actions reasonably requested by the
Company Board (whether during or after the Employment Period) to establish and
confirm the Company's or such Subsidiary's or such Affiliate's ownership
(including, without limitation, assignments, consents, powers of attorney, and
other instruments).

              (4)    THIRD PARTY INFORMATION. Executive understands that the
Company and its Affiliates will receive from third parties confidential or
proprietary information ("THIRD PARTY INFORMATION") subject to a duty on the
Company's and its Affiliates' part to maintain the confidentiality of such
information and to use it only for certain limited purposes. During the
Employment Period and thereafter, and without in any way limiting the provisions
of SECTION 8(a) above, Executive will hold Third Party Information in the
strictest confidence and will not disclose to anyone (other than personnel of
the Company or its Affiliates who need to know such information in connection
with their work for the Company or its Affiliates) or use, except in connection
with his work for the Company or its Affiliates, Third Party Information unless
expressly authorized by the Company Board in writing.

              (5)    USE OF INFORMATION OF PRIOR EMPLOYERS. During the
Employment Period, Executive will not improperly use or disclose any
confidential information or trade secrets, if any, of any former employers or
any other person to whom Executive has an obligation of confidentiality, and
will not bring onto the premises of the Company or any of the Company's
Affiliates any unpublished documents or any property belonging to any former
employer or any other person to whom Executive has an obligation of
confidentiality unless consented to by in writing the former employer or person.

                                      -14-
<Page>

              9.     NONCOMPETITION AND NONSOLICITATION. Executive acknowledges
that in the course of his employment with the Employer he will become familiar
with the Company's and its Subsidiaries' trade secrets and with other
confidential information concerning the Company and such Subsidiaries and that
his services will be of special, unique and extraordinary value to the Employer.
Therefore, Executive agrees that:

              (1)    NONCOMPETITION. During the Employment Period and for a
period of eighteen months thereafter (or a period of twelve months thereafter at
any time after a Sale of the Company) (the "NONCOMPETE PERIOD"), he shall not,
within the United States, directly or indirectly own, manage, control,
participate in, consult with, render services for, or in any manner engage in
any business in which the Company or any of its Subsidiaries engaged prior to
the Separation.

              (2)    NONSOLICITATION. During the Noncompete Period, and except
in respect of Executive's executive assistant(s), Executive shall not directly
or indirectly through another entity (i) induce or attempt to induce any
employee of the Company or its Subsidiaries to leave the employ of the Company
or such Subsidiary, or in any way interfere with the relationship between the
Company and any Subsidiary and any employee thereof, (ii) hire any person who
was an employee of the Company and any Subsidiary within 180 days prior to the
time such employee was hired by Executive, (iii) induce or attempt to induce any
customer, supplier, licensee or other business relation of the Company and any
Subsidiary to cease doing business with the Company or such Subsidiary or in any
way interfere with the relationship between any such customer, supplier,
licensee or business relation and the Company and any Subsidiary or (iv)
directly or indirectly acquire or attempt to acquire an interest in any business
relating to the business of the Company and any Subsidiary and with which the
Company and any Subsidiary has entertained discussions or has requested and
received information relating to the acquisition of such business by the Company
and any Subsidiary in the two-year period immediately preceding a Separation.

              (3)    ENFORCEMENT. If, at the time of enforcement of SECTION 8 or
this SECTION 9, a court holds that the restrictions stated herein are
unreasonable under circumstances then existing, the parties hereto agree that
the maximum duration, scope or geographical area reasonable under such
circumstances shall be substituted for the stated period, scope or area and that
the court shall be allowed to revise the restrictions contained herein to cover
the maximum duration, scope and area permitted by law. Because Executive's
services are unique and because Executive has access to confidential
information, the parties hereto agree that money damages would be an inadequate
remedy for any breach of this Agreement. Therefore, in the event a breach or
threatened breach of Section 8 or this Section 9 of this Agreement, the Employer
or its successors or assigns may, in addition to other rights and remedies
existing in their favor, apply to any court of competent jurisdiction for
specific performance and/or injunctive or other relief in order to enforce, or
prevent any violations of, the provisions of Section 8 or this Section 9
(without posting a bond or other security).

              (4)    ADDITIONAL ACKNOWLEDGMENTS. Executive acknowledges that the
provisions of this SECTION 9 are in consideration of: (i) employment with the
Employer, (ii) the

                                      -15-
<Page>

issuance of the Executive Stock and (iii) additional good and valuable
consideration as set forth in this Agreement. In addition, Executive agrees and
acknowledges that the restrictions contained in SECTION 8 and this SECTION 9 do
not preclude Executive from earning a livelihood, nor do they unreasonably
impose limitations on Executive's ability to earn a living. In addition,
Executive acknowledges (i) that the business of the Company and its Subsidiaries
will be national in scope and without geographical limitation and (ii)
notwithstanding the state of incorporation or principal office of the Company or
any of its Subsidiaries, or any of their respective executives or employees
(including, without limitation, the Executive), it is expected that the Company
and its Subsidiaries will have business activities and have valuable business
relationships within its industry throughout the United States. In addition,
Executive agrees and acknowledges that the potential harm to the Company of the
non-enforcement of SECTION 8 and this SECTION 9 outweighs any potential harm to
Executive of its enforcement by injunction or otherwise. Executive acknowledges
that he has carefully read this Agreement and has given careful consideration to
the restraints imposed upon Executive by this Agreement, and is in full accord
as to their necessity for the reasonable and proper protection of confidential
and proprietary information of the Employer now existing or to be developed in
the future. Executive expressly acknowledges and agrees that each and every
restraint imposed by this Agreement is reasonable with respect to subject
matter, time period and geographical area.

deliver to the Company Board a written notice of objection within ten days after
delivery of the Repurchase Notice (or if no Repurchase Notice is delivered, then
within ten days after delivery of the Supplemental Repurchase Notice). Upon
receipt of Executive's written notice of objection, the Company Board and
Executive will negotiate in good faith to agree on such Fair Market Value. If
such agreement is not reached within 30 days after the delivery of the
Repurchase Notice (or if no Repurchase Notice is delivered, then within 30 days
after the delivery of the Supplemental Repurchase Notice), Fair Market Value
shall be determined by an appraiser jointly selected by the Company Board and
Executive, which appraiser shall submit to the Company Board and Executive a
report within 30 days of its engagement setting forth such determination. If the
parties are unable to agree on an appraiser within 45 days after delivery of the
Repurchase Notice or the Supplemental Repurchase Notice, within seven days, each
party shall submit the names of four nationally recognized investment banking
firms, and each party shall be entitled to strike two names from the other
party's list of firms, and the appraiser shall be selected by lot from the
remaining four investment banking firms. The expenses of such appraiser shall be
borne by Executive unless the appraiser's valuation is more than 10% greater
than the amount determined by the Company Board, in which case, the expenses of
the appraiser shall be borne by the Company. The determination of such appraiser
as to Fair Market Value shall be final and binding upon all parties. If the
Repurchase Option is exercised within 90 days after a Separation, then Fair
Market Value shall be determined as of the date of such Separation; thereafter,
Fair Market Value shall be determined as of the date the Repurchase Option is
exercised.

              12.    GENERAL PROVISIONS.

              (1)    TRANSFERS IN VIOLATION OF AGREEMENT. Any Transfer or
attempted Transfer of any Executive Stock in violation of any provision of this
Agreement shall be void, and the Company shall not record such Transfer on its
books or treat any purported transferee of such Executive Stock as the owner of
such stock for any purpose.

              (2)    SEVERABILITY. Whenever possible, each provision of this
Agreement will 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 invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or any other jurisdiction, but this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

              (3)    ENTIRE AGREEMENT. This Agreement, those documents expressly
referred to herein and other documents of even date herewith embody the complete
agreement and understanding among the parties and supersede and preempt 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.

              (4)    COUNTERPARTS. This Agreement may be executed in separate
counterparts (including, without limitation, by means of telecopied signature
pages), each of which is deemed to be an original and all of which taken
together constitute one and the same agreement.

              (5)    INTENDED THIRD-PARTY BENEFICIARIES. The Investors are
intended to be third-party beneficiaries to this entire Agreement and the rights
and obligations of the parties hereto. It is understood and agreed by the

every provision hereof. Except as expressly provided herein, no other third
parties are intended by the parties hereto to be beneficiaries hereof.

successors and assigns (including, without limitation, subsequent holders of

this Agreement shall not be assignable except in connection with a permitted
transfer of Executive Stock hereunder.

              (7)    CHOICE OF LAW. The corporate law of the State of Delaware
will govern all questions concerning the relative rights of the Company and its
stockholders. All other questions concerning the construction, validity and
interpretation of this Agreement and the exhibits hereto will 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 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.

              (8)    REMEDIES. Each of the parties to this Agreement (including,
without limitation, the Investors) will be entitled to enforce its rights under
this Agreement specifically, to recover damages and costs (including, without
limitation, attorney's fees) caused by any breach of any provision of this
Agreement and to exercise all other rights existing in its favor. The parties
hereto agree and acknowledge that money damages may not be an adequate remedy
for any breach of the provisions of this Agreement and that any party may in its
sole discretion apply to any court of law or equity of competent jurisdiction
(without posting any bond or deposit) for specific performance and/or other
injunctive relief in order to enforce or prevent any violations of the
provisions of this Agreement.

              (9)    AMENDMENT AND WAIVER. The provisions of this Agreement may
be amended and waived only with the prior written consent of the Company, the
Employer, Executive and the Majority Holders (as defined in the Purchase
Agreement).

              (10)   INSURANCE. The Company, at its discretion, may apply for
and procure in its own name and for its own benefit life and/or disability
insurance on Executive in any amount or amounts considered available. Executive
agrees to cooperate in any medical or other examination, supply any information,
and to execute and deliver any applications or other instruments in writing as
may be reasonably necessary to obtain and constitute such insurance.

              (11)   BUSINESS DAYS. If any time period for giving notice or
taking action hereunder expires on a day which is a Saturday, Sunday or holiday
in the state in which the Company's chief executive office is located, the time
period shall be automatically extended to the business day immediately following
such Saturday, Sunday or holiday.

              (12)   INDEMNIFICATION AND REIMBURSEMENT OF PAYMENTS ON BEHALF OF
EXECUTIVE. The Company and its Subsidiaries shall be entitled to deduct or
withhold from any amounts owing from the Company or any of its Subsidiaries to
Executive any federal, state, local or foreign withholding taxes, excise taxes,
or employment taxes ("TAXES") imposed with respect to Executive's compensation
or other payments from the Company or any of its Subsidiaries or Executive's
ownership interest in the Company, including, without limitation, wages,
bonuses,

                                      -23-

dividends, the receipt or exercise of stock options and/or the receipt or
vesting of restricted stock. In the event the Company or its Subsidiaries does
not make such deductions or withholdings, Executive shall indemnify the Company

such Taxes, together with any interest, penalties and related expenses thereto.

              (13)   SURVIVAL. This Agreement (except for the provisions of
SECTIONS 7(a) and (b)) shall survive a Separation and shall remain in full force
and effect after such Separation.

              (14)   GENERALLY ACCEPTED ACCOUNTING PRINCIPLES; ADJUSTMENTS OF
NUMBERS. Where any accounting determination or calculation is required to be
made under this Agreement or the exhibits hereto, such determination or
calculation (unless otherwise provided) shall be made in accordance with
generally accepted accounting principles, consistently applied, except that if
because of a change in generally accepted accounting principles the Company
would have to alter a previously utilized accounting method or policy in order
to remain in compliance with generally accepted accounting principles, such
determination or calculation shall continue to be made in accordance with the
Company's previous accounting methods and policies. All numbers set forth herein
which refer to share prices or amounts will be appropriately adjusted to reflect
stock splits, stock dividends, combinations of shares and other
recapitalizations affecting the subject class of stock.

              (15)   DEEMED TRANSFER OF EXECUTIVE STOCK. If the Company (and/or
the Investors and/or any other Person acquiring securities) shall make
available, at the time and place and in the amount and form provided in this
Agreement, the consideration for the Executive Stock to be repurchased in
accordance with the provisions of this Agreement, then from and after such time,
the Person from whom such shares are to be repurchased shall no longer have any
rights as a holder of such shares (other than the right to receive payment of
such consideration in accordance with this Agreement), and such shares shall be
deemed purchased in accordance with the applicable provisions hereof and the
Company (and/or the Investors and/or any other Person acquiring securities)
shall be deemed the owner and holder of such shares, whether or not the
certificates therefor have been delivered as required by this Agreement.

              (16)   NO PLEDGE OR SECURITY INTEREST. The purpose of the
Company's retention of Executive's stock certificates and executed stock powers
is solely to facilitate the repurchase provisions set forth in SECTION 4 herein
and does not constitute a pledge by Executive of, or the granting of a security
interest in, the underlying stock.

this provision, the Company hereby unconditionally and irrevocably guarantees to
Executive the due, prompt and complete performance of, and compliance with, all
obligations, covenants, terms, conditions and undertakings of the Employer
contained in this Agreement in accordance with the terms hereof, including,

              contemplated hereby, regardless of any investigation made by the
