Signature Page hereto ("Executive"). This Agreement is entered into individually
with each of the Executives named on the signature pages hereto. Except for the
numbered matters in [__] which are reflected on each individual Executive's
Annex A attached hereto, this Agreement shall be the same for each of the
-------
Executives named on the signature pages; provided, however, that all references
herein to Executive or Executive Stock shall be deemed to refer only to such
individual Executive and his Executive Stock (including the portion of Executive
Stock held by such Executive's Permitted Transferees).


                                   Recitals
                                   --------
     A. The Company and Executive desire to enter into an agreement pursuant to
which Executive will purchase, and the Company will sell, [1] shares of the
Company's Common Stock, par value $.01 par value per share (the "Common Stock")
and [2] shares of the Company's Class A Preferred Stock, $.01 par value per
share (the "Preferred Stock"). All shares of Common Stock and Preferred Stock
purchased by an Executive are referred to herein as "Executive Stock" (as
further defined in Section 10).
                   ----------

     B. The execution and delivery of this Agreement by the Company and
Executive is a condition to the purchase of shares of Common Stock and Preferred
Stock by Thayer ITech Holdings, L.L.C. (the "Investor") pursuant to a purchase
agreement between the Company and the Investor (the "Equity Purchase
Agreement"). Certain provisions of this Agreement are intended for the benefit
of, and will be enforceable by, the Investor.

     C. Certain definitions are set forth in Section 10 of this Agreement.
                                             ----------

                                    Agreement
                                    ---------

     The parties hereto agree as follows:

                     PROVISIONS RELATING TO EXECUTIVE STOCK

     1. Purchase and Sale of Executive Stock.
        ------------------------------------

        (a) Pursuant to the terms of this Agreement, Executive will purchase,
and the Company will sell, an aggregate of [1] shares of Common Stock at a price
of $.10 per share. At the time of such purchase, the Company will deliver to
Executive the certificates

                                       1
<PAGE>

representing such Executive Stock, and Executive will deliver to the Company [3]
in the aggregate amount of $[4].

     (b) Within 30 days after Executive purchases any Executive Stock from the
Company, Executive will make an effective election with the Internal Revenue
Service under Section 83(b) of the Internal Revenue Code and the regulations
promulgated thereunder in the form of Annex A attached hereto.
                                      -------

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

          (i)   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.

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

          (iii) 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.

          (iv)  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.

          (v)   This Agreement constitutes the legal, valid and binding
     obligation of Executive, enforceable in accordance with its terms, 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.

          (vi)  Executive is a resident of [5].

     (d)  As an inducement to the Company to issue the Executive Stock to
Executive, 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 or affect the right of the Company to terminate
Executive's employment at any time for any reason pursuant to Section 7 hereof.
                                                              ---------

     2. Vesting of Certain Executive Stock.
        ----------------------------------
        (a) Except as otherwise provided in Section 2(d) below, [6] shares or
                                            ------------
50% of the Common Stock issued pursuant to Section 1(a) above (the "Time Vesting
                                           ------------
Shares") shall 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
Affiliates:

                                                       Cumulative Percentage of
                            Date                       Common Stock to be Vested
                            ----                       -------------------------
                   First Anniversary of
                   the Date hereof                               25%

                   Second Anniversary
                   of the Date hereof                            50%

                   Third Anniversary
                   of the Date hereof                            75%

                   Fourth Anniversary
                   of the date hereof                           100%

Notwithstanding the foregoing, if Executive ceases to be employed by the Company
or its Affiliates on any date after the first anniversary of the date hereof but
prior to the fourth anniversary, the cumulative percentage of Time Vesting
Shares to become vested will be determined on a pro rata basis according to the
number of full months elapsed since the prior anniversary date (for example if 5
full months have elapsed since the first anniversary date, then an additional
5/12 (10.41%) or a total of 35.41% shall have become vested). Notwithstanding
the foregoing sentence, (i) all Time Vesting Shares shall become vested in the
event of a Sale of the Company and (ii) an additional 20% of all Time Vesting
Shares (not to exceed 100%) shall become vested in the event that Executive has
been terminated without Cause. Notwithstanding the foregoing, in the event that
Executive is terminated for Cause prior to the earlier of (i) the fourth
anniversary of the date hereof or (ii) the effective date of an Initial Public
Offering, then all Time Vesting Shares (whether or not then vested) will be
deemed to be "Unvested Shares" for purposes of this Agreement.

     (b) [6] shares or 50% of the Common Stock issued pursuant to Section 1(a)
above (the "Performance Vesting Shares") shall become vested in accordance with
the following schedule if the Investor shall have earned or deemed to have

                                                     of  Performance
                  Return                             Vesting Shares "Vested"
                  ------                             -----------------------
                   25.00%                                      25.00%
                   26.50%                                      32.50%
                   28.00%                                      40.00%
                   29.50%                                      47.50%
                   31.00%                                      55.00%

                                      -3-
<PAGE>

                   32.50%                                      62.50%
                   34.00%                                      70.00%
                   35.50%                                      77.50%
                   37.00%                                      85.00%
                   38.50                                       92.50%
                   40.00% or more                             100.00%

The above "Return" shall be calculated (each a "Date of Determination") at any
time after Market Liquidity exists (i.e., at any date that Market Liquidity
exists and the Investor would have achieved a specified Return set forth above
as of such date if it sold all of its remaining Company equity securities on
such date, the requisite percentage of Performance Shares will vest) and at the
following times: (i) upon a Sale of the Company and (ii) after the effective
date of an Initial Public Offering upon the occurrence of either (A) Executive's
death or permanent disability or (B) upon Executive's having been terminated
without Cause. Notwithstanding anything in this Agreement to the contrary, all
Performance Vesting Shares then outstanding will become Vested Shares on the
eighth anniversary of the date hereof.

     (c) All shares of Preferred Stock acquired by Executive will vest
immediately upon such purchase.

     (d) Upon the occurrence of a Sale of the Company, all Time Vesting Shares
which have not yet become vested shall become vested at the time of such event.
Shares of Executive Stock which have become vested (whether pursuant to Section
                                                                        -------
2(a) or 2(b) above or upon purchase thereof (i.e., the shares referred to in
----    ----
Section 2(c) above)) are referred to herein as "Vested Shares," and all other
------------
shares of Executive Stock are referred to herein as "Unvested Shares".

     3. Repurchase Option.
        -----------------

     (a) In the event that Executive ceases to be employed by the Company and
its Affiliates for any reason (the "Termination"), then, subject to Section 3(g)
                                                                    ------------
below, all of the Executive Stock (whether held by Executive or one or more of
Executive's Permitted Transferees) will be subject to repurchase by the Company
and the Investor pursuant to the terms and conditions set forth in this Section
                                                                        -------
3 (the "Repurchase Option").
-
     (b) In the event of Termination, (i) the purchase price for each Unvested
Share of Common Stock will be the lower of (A) Executive's Original Cost for
such share and (B) the Fair Market Value for such share; (ii) the purchase price
for each Vested Share of Common Stock will be the Fair Market Value for such
share; and (iii) the purchase price for each share of Preferred Stock will be
the Liquidation Value of such share (as defined in the Company's Restated
Certificate of Incorporation) plus all accrued and unpaid dividends thereon.

     (c) Subject to Section 3(g) below, the Board shall use its reasonable best
                    ------------
efforts to purchase all or any portion of the Unvested Shares and the Vested
Shares subject to repurchase by delivering written notice (the "Repurchase
Notice") to the holder or holders of the Executive Stock within 90 days after
Termination (a "Company Repurchase Option"). The

                                      -4-
<PAGE>

Repurchase Notice will set forth the number of Unvested Shares and Vested Shares
of each class to be acquired from each holder pursuant to such Company
Repurchase Option (it being understood that the Company shall first apply all
amounts utilized to repurchase Executive Stock to the repurchases of Unvested
Shares, with the balance, if any, to be utilized to repurchase Vested Shares),
the aggregate consideration to be paid for such shares and the time and place
for the closing of the transaction.

     (d) If for any reason the Company does not elect to purchase all of the
Executive Stock pursuant to the Repurchase Option, the Investor shall be
entitled to exercise any unutilized portion of the Company Repurchase Option for
the repurchase of shares (it being understood that the Investor shall first
apply all amounts utilized to repurchase Executive Stock to the repurchases of
Unvested Shares, with the balance, if any, to be utilized to repurchase Vested
Shares) of any class of 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 60 days
after Termination, the Company shall give written notice (the "Option Notice")
to the Investor setting forth the number of Available Shares and the purchase
price for the Available Shares. The Investor may elect to purchase any or all of
the Available Shares by giving written notice to the Company within twenty (20)
days after the Option Notice has been given by the Company. As soon as
practicable, and in any event within ten (10) days, after the expiration of the
twenty (20) day period set forth above, the Company shall notify each holder of
Executive Stock to be repurchased as to the number of shares of each class being
purchased from such holder by the Investor (the "Supplemental Repurchase
Notice"). At the time the Company delivers the Supplemental Repurchase Notice to
the holder(s) of Executive Stock, the Company shall also deliver written notice
to the Investor setting forth the number of shares of each class the Investor
will purchase, the aggregate purchase price and the time and place of the
closing of the transaction.

     (e) The closing of the purchase of the 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 45 days after the delivery of the Repurchase Notice. The Company will
pay for the 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. The Investor will pay for the Executive Stock to be
purchased by it pursuant to the Repurchase Option by delivery of a check or wire
transfer of funds in the aggregate amount of the purchase price for such shares.
The Company and the Investor will be entitled to receive customary
representations and warranties from the sellers regarding such sale.

     (f) Notwithstanding anything to the contrary contained in this Agreement,
all repurchases of Executive Stock by the Company shall be subject to any
customary restrictions contained in applicable corporate and securities laws and
in the Company's and its Subsidiaries' debt and equity financing agreements. If
any such restrictions prohibit the repurchase of Executive Stock hereunder which
the Company is otherwise entitled or required to make, the Company may make such
repurchases as soon as it is permitted to do so under such restrictions.

                                      -5-

     (g) Any shares of Executive Stock not purchased by the Company or the
Investor pursuant to a Repurchase Option after Termination of the Executive's
employment with the Company for any reason shall vest in full and shall no
longer be subject to the provisions of Sections 2 or 3 of this Agreement.
                                       ----------    -
     (h) Notwithstanding any other provision of this Agreement, after the
closing date of an Initial Public Offering, Vested Shares shall not be subject

subject to certain restrictions on transfer and certain tag-along and drag-along
rights which are provided for in the Stockholders Agreement, and nothing in this
Agreement shall be deemed to amend, modify or limit in any way the restrictions
on the issuance of shares of Preferred Stock or Common Stock set forth in the
Equity Purchase Agreement, in the Stockholders Agreement or in any other
agreement to which the Company is bound. Except for Permitted Transfers and
Transfers pursuant to the Repurchase Option, the Executive may not Transfer or

                    (4) Executive's engaging in intentional or willful conduct
    constituting a breach of Sections 8 or 9 hereof.

    In order for the termination to be effective: Executive must be notified in
    writing (which writing shall specify the cause in reasonable detail) of any
    termination of his employment for Cause or Performance Cause. Executive will
    then have the right, within ten days of receipt of such notice, to file a
    written request for review by the Company. In such case, Executive will be
    given the opportunity to be heard, personally or by counsel, by the Board
    and a majority of the Directors must thereafter confirm that such
    termination is either for Cause or Performance Cause. If the Directors do
    not provide such confirmation, the termination shall be treated as other
    than for Cause or Performance Cause. Notwithstanding anything to the
    contrary contained in this paragraph, Executive shall have the right after
    termination has occurred to appeal any determination by the Board to
    arbitration in accordance with the provisions of Section 12(h) hereof.
                                                     -------------

           (E) Executive's voluntary resignation by the delivery to the Board of
           written notice from Executive that Executive has resigned with or
           without Good Reason; provided that in either event, Executive shall

           resignation. "Good Reason" shall mean Executive's resignation from
           employment with the Company within 45 days after the occurrence of
           any one of the following:

                    (1) the failure of the Company to pay an amount owing
           to Executive hereunder after Executive has provided the Company with
           written notice of such failure and such payment is in fact owed and
           has not thereafter been made within 15 days of the delivery of such
           written notice;

                    (2) a substantial reduction in Executive's duties from

<PAGE>

                    (3) the required relocation of Executive from the

                                                                ------------
      shall constitute a resignation by the Execution without Good Reason unless
      such notice fulfills the requirements of Section 7(c)(i)(E)(1) , (2) or
                                               ---------------------   ---
      (3) above.
      ---

           (ii) Rights on Termination.
                ---------------------

                (A) In the event that termination is by Executive with Good
      Reason or by the Company without either Cause or Performance Cause, the
      Company will continue to pay Executive a monthly portion of the Annual
      Base Salary plus a monthly portion of the Executive's bonus for the prior
      year for a period equal to 12 months commencing on the date of termination
      on regular salary payment dates. In the event that termination is by the
      Company for Performance Cause, the Company will continue to pay Executive
      a monthly portion of the Annual Base Salary for a period equal to six-
      months commencing on the date of termination on regular salary payment
      dates. The payments to Executive pursuant to the foregoing two sentences
      are referred to as the "Severance Payments."

                (B) If the Company terminates Executive's employment for
      Cause, if Executive retires or if Executive resigns without Good Reason
      (including by operation of the last paragraph of Section 7(c)(i)(E)), the
                                                       -------------------
      Company's obligations to pay any compensation or benefits under this
      Agreement will cease effective as of the date of termination. Executive's
      right to receive any health or other benefits will be determined under the
      provisions of applicable plans, programs or other coverages.

                (C) If Executive's employment terminates because of Executive's
      death or disability, the Company will pay Executive or his estate an
      amount, if any, equal to his maximum bonus for the current year prorated
      to reflect the number of days Executive has worked during the year in
      which he dies or becomes disabled (such amount to be paid after the end of
      such year when bonuses are normally paid to other senior executives of the
      Company).

      Notwithstanding the foregoing, the Company's obligation to Executive for
severance payments or other rights under either subparagraphs (A) or (B) above
                                                -----------------    ---
shall cease if Executive is in violation of the provisions of Sections 8 or 9
                                                              ---------------
hereof. Until such time as Executive has received all of his Severance Payments,
he will be entitled to continue to receive any health, life, accident and
disability insurance benefits provided by the Company to Executive under this
Agreement. If Executive dies or is permanently disabled, then Executive or his
estate shall be

                                      -10-
<PAGE>

entitled to any disability income or life insurance payments from any insurance
policies paid for by the Company or its Affiliates as specified in such
policies.

     (d) Term of Employment. Unless Executive's employment under this Agreement
         ------------------
is sooner terminated as a result of Executive's termination in accordance with
the provisions of Section 7(c) above, Executive's employment under this
                  ------------
Agreement shall commence on August 12, 1999 and shall terminate on the third
anniversary of the date thereof (the "Service Term"); provided, however, that
Executive's employment under this Agreement, and the Service Term, shall be
automatically renewed for one-year periods commencing on the third anniversary
of the date hereof and, thereafter, on each successive anniversary of such date
unless either the Company or Executive notifies the other party in writing
within six months prior to any such anniversary that it or he desires to
terminate Executive's employment under this Agreement as of such anniversary.
All references herein to "Service Term" shall include any renewals thereof.

  8. Confidential Information and Goodwill; Inventions. Executive
     -------------------------------------------------
acknowledges and agrees that:

     (a) As a necessary function of Executive's employment hereunder, Executive
will have access to and utilize Confidential Information which constitutes a
valuable and essential asset of the Company's business.

     (b) The Confidential Information, observations and data obtained by him
during the course of his performance under this Agreement concerning the
business and affairs of the Company are the property of the Company, including
information concerning the acquisition opportunities in or reasonably related to
the Business of which Executive becomes aware during the Service Term.
Therefore, Executive agrees that he will not disclose to any unauthorized person
or use for his own account any of the Confidential Information without the
Board's written consent. Executive agrees to deliver to the Company at the
termination of his employment, or at any other time the Company may request, all
memoranda, notes, plans, records, reports and other documents (including copies
thereof) relating to the Company, the Business or any other Confidential
Information.

     (c) All inventions, innovations, developments, improvements, methods,
designs, analyses, drawings, software, copyrights, patents, trademarks, reports
and all similar or related information (whether or not patented or patentable)
developed by Executive during the Service Term which (i) directly or indirectly
relate to the Company or its Affiliates or the Business, or (ii) result from any
work performed by Executive while employed by the Company or its Affiliates
shall belong to the Company and its Affiliates. Executive shall promptly
disclose all such inventions to the Board and perform all actions reasonably
requested by the Board (whether during or after the Service Term) to establish
and confirm such ownership (including, without limitation, assignments,
consents, powers of attorney and other instruments).

  9. Noncompetition and Nonsolicitation.
     ----------------------------------
     (a) Noncompetition. Executive acknowledges that in the course of his
         --------------
employment with the Company he will become familiar with the Company's and its
Affiliates'

                                      -11-
<PAGE>

trade secrets and with other confidential information concerning the Company and
that his services will be of special, unique and extraordinary value to the
Company and its Affiliates. Therefore, Executive agrees that, during the Service
Term and for a period of 12 months after termination thereof; provided, however,
that in the event that Executive has been terminated by the Company without
either Cause or Performance Cause or the Executive has resigned for Good Reason,
such period of time after the Service Term shall be limited to the time period
during which the Executive is entitled to receive Severance Payments
(collectively, the "Noncompete Period"), he shall not directly or indirectly
own, manage, control, participate in, consult with, render services for, or in
any manner engage in any business competing with the Business of the Company and
its Subsidiaries or any businesses with which the Executive has knowledge that
the Company or its Subsidiaries have firm documented or Board-approved plans to
engage in at the time of the termination of the Executive's employment with the
Company.

     (b) Nonsolicitation. During the Noncompete Period and for a period of 12
         ---------------
months thereafter, Executive shall not directly or indirectly through another
entity (i) induce or attempt to induce any senior management employee of the
Company or any Subsidiary or, to the actual knowledge of the Executive, any
other employee of the Company or any Subsidiary, to leave the employ of the
Company or such Subsidiary, or in any way interfere with the relationship
between the Company or any Subsidiary and any employee thereof or (ii) induce or
attempt to induce any customer, supplier, vendor, licensee or other business
relation of the Company or any Subsidiary to cease doing business with the
Company or such Subsidiary, or to modify its business relationship with the
Company in a manner adverse to the Company or any Subsidiary, or in any way
disparage the Company or its Subsidiaries to any such customer, supplier,
vendor, licensee or business relation of the Company or any Subsidiary.

     (c) Enforcement. The Executive understands and agrees that the sale of the
         -----------
Executive Stock to Executive pursuant to Section 1 of this Agreement and the
                                         ---------
terms and conditions of Executive's employment hereunder are in consideration
for Executive's covenants contained in Section 8 and 9 of this Agreement. If, at
                                       ---------     -
the time of enforcement of Section 8 or 9 of this Agreement, 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 this Agreement, the
Company 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 hereof (without posting a bond or
other security).

     12. General Provisions.
         ------------------

     (a) Expenses. The Company agrees to pay Executive's reasonable legal,
         --------
accounting and other expenses incurred in connection with the negotiation and
execution of this Agreement and the consummation of the transactions
contemplated by this Agreement; provided, however, that the Company will in no
event be responsible for any such expenses incurred in excess of $10,000 for
Executive and all other executives executing signature pages hereto as a group.

     (b) Transfers in Violation of Agreements. Any Transfer or attempted
         -------------------------------------
Transfer of any Executive Stock in violation of any provision of this Agreement
or the Stockholders 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.

     (c) Severability. Subject to the provisions of Section 9(c) above, 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.

     (d) Complete 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.

     (e) Counterparts. This Agreement may be executed in separate counterparts,
         ------------
each of which is deemed to be an original and all of which taken together
constitute one and the same agreement.

     (f) Successors and Assigns. Except as otherwise provided herein, this
         ----------------------
Agreement shall bind and inure to the benefit of and be enforceable by
Executive, the Company, the Investor and their respective successors and assigns
(including subsequent holders of Executive Stock); provided that the rights and
obligations of Executive under this Agreement shall not be assignable except as
otherwise specifically provided herein.

     (g) Choice of Law. The corporate law of the Company's state of
         -------------
incorporation 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
Commonwealth of Virginia, without giving effect to any choice of law or conflict
of law provision or rule (whether of the Commonwealth of Virginia or any other
jurisdiction) that would cause the application of the laws of any jurisdiction
other than the Commonwealth of Virginia.

     (h) Remedies and Arbitration. Each of the parties to this Agreement
         ------------------------
(including the Investor) will be entitled to enforce its rights under this
Agreement to recover damages and costs (including reasonable attorney's fees)
caused by any breach of any provision of this Agreement and to exercise all
other rights existing in its favor. Except for the remedies of the Company
provided in Section 9(c) hereof, the parties hereto agree to (i) initially
            ------------
submit any dispute arising out of or relating to this Agreement to mediation and
(ii) in the event such mediation is unsuccessful, to submit any disputes arising
out of or relating to this Agreement to binding arbitration in Washington, D.C.
administered by the American Arbitration Association under its Commercial
Arbitration Rules, before a panel of one arbitrator (such arbitrator to be
selected by lot or the mutual agreement of two other arbitrators, one chosen by
the Company and one by the Executive), and judgment on the award rendered by the
arbitrator may be entered into any court having jurisdiction thereof. The
prevailing party in any arbitration shall be entitled to recover its reasonable
attorneys' fees and costs from the other party or parties.

     (i) Amendment and Waiver. The provisions of this Agreement may be amended
         --------------------
and waived only with the prior written consent of the Company, Executive and the
Investor.

     (j) 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

                                      -18-
<PAGE>

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.

     (k) Termination. This Agreement shall survive the termination of
         -----------
Executive's employment with the Company and shall remain in full force and
effect after such termination.

     (l) 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.
