the Sellers for any breaches of the representations and warranties in the
Agreement.  A copy of the Escrow Agreement is attached as Exhibit 2.3 to this

Current Report on Form 8-K.

     The members of management of DVA, as well as the other employees of DVA,
continue as employees.

     1.6. Default by any Seller.  If any Seller fails to deliver to Buyer at

<PAGE>

                                      -3-

Stock, or (b) refuse to make such acquisition and thereby terminate all of its
obligations hereunder, in either case without prejudice to its rights against
such defaulting Seller.

     1.7. Tax-Free Reorganization.  The parties hereto intend that the exchange
          -----------------------
of Company Stock for Buyer Stock contemplated by this Agreement shall be
pursuant to a reorganization described in Section 368(a)(1)(B) of the Internal
Revenue Code of 1986, as amended (the "Code").  The Buyer Stock issued in the
                                       ----
reorganization is intended to be issued solely in exchange for the Company
Stock, and no other transaction is intended to be an adjustment to the
consideration paid for the Company Stock.  The amount of Buyer Stock to be
received by the Sellers was determined by arms-length bargaining.  Buyer
represents as of the date hereof, and as of the Closing Date, that it presently
intends to continue the historic business of the Company or use a significant
portion of the business assets of the Company in a business.  In addition, the
parties shall (i) comply with the information reporting requirement of Treasury
Regulation Section 1.368-3, and (ii) unless there has been a Final Determination
that the exchange of Company Stock for Buyer Stock does not constitute a
reorganization described in Section 368(a)(1)(B) of the Code, not take a
position on any tax returns inconsistent with this Section 1.7. Notwithstanding
the foregoing, each of the parties hereto has consulted its own tax advisors
with respect to the tax consequences of this transaction, and the Buyer shall
not have any obligation, of indemnification or otherwise, in connection with the
tax consequences of the transaction to any other party hereto.  For purposes of
this Section 1.7, a "Final Determination" shall mean (i) with respect to federal
Taxes, a "determination" as defined in Section 1313(a) of the Code or execution
of an Internal Revenue Service Form 870 or 870AD and, with respect to Taxes
other than federal Taxes, any final determination in respect of any Tax or
adjusted Tax basis issue that, under applicable law, is not subject to further
review, appeal or modification through proceedings or otherwise, (ii) any final
disposition of a Tax or adjusted Tax basis issue by reason of the expiration of
the applicable statute of limitations, or (iii) the determination by Buyer that
such position is required by law or administrative pronouncement.

     1.8  Waiver. The Company and each of the Sellers hereby agrees to waive
          ------
their rights pursuant to Article VI (Certificate of Stock and Transfers) of the
Company's By-Laws with respect to the transactions contemplated by this
Agreement.

its business as now conducted except for such governmental licenses, permits,

properties, assets, liabilities (including contingent liabilities), or results

subsidiaries, taken as a whole; provided, however that the effects of any

events, circumstances or conditions resulting solely from changes, developments,
circumstances or conditions (political, economic, or regulatory) that adversely
affect generally the markets where the business of the Company or any of its
Subsidiaries is operated or affect generally industries engaged in the
consulting, software engineering and project management services (including
proposed legislation or regulation by any governmental or regulatory body or the
introduction of any technological changes in such industries) will not
constitute a Material Adverse Effect.

     (b)  The copies of the Company's certificate of incorporation and by-laws,
as amended to date, which have been delivered to Buyer, in each case certified
by the Company's Secretary, are true, correct and complete and are in full force
and effect.

issued and are fully paid and are owned by Sellers as shown on Schedule 2.2.
                                                               ------------
All outstanding shares in the capital of the Delaware Subsidiary have been duly

Except as set forth in this Section or otherwise set forth on Schedule 2.2,

phantom or other equity interests of the Company, (ii) securities of the Company
convertible into or exchangeable for shares of capital stock or other securities
of the Company or (iii) options or other rights to acquire from the Company any

whose outstanding shares or securities (representing the right to vote for the
election of directors or other managing authority) are, or (ii) which does not

authorizations, consents and approvals required to carry on its business as now
conducted and is duly qualified to do business as a foreign corporation and is
in good standing in each jurisdiction where the character of the property owned
or leased by it or the nature of its activities make such qualification
necessary, except for those jurisdictions where failure to be so qualified would
not, individually or in the aggregate, have a Material Adverse Effect.  All
Subsidiaries and their respective jurisdictions of incorporation are identified
on Schedule 2.3.  The Delaware Subsidiary has no subsidiaries.
   ------------

          (b) All of the outstanding capital stock of, or other ownership
interests in, each Subsidiary is owned by the Company, directly or indirectly,

                               -----------------
directly or indirectly, or in whole or in part, (i) engage in any activity which
is directly competitive with the business of the Company or the Buyer as
conducted during the one (1) year period immediately preceding the Closing or
(ii) become interested in any Person engaged in such activity in any capacity
including, but not limited to, as a partner, shareholder, principal, agent,
representative, supplier, trustee, employee or consultant.  During the
Restricted Period, no Seller shall, directly or indirectly, hire or solicit any
employee of the Buyer or the Company or encourage, in any way, any such employee
to leave such employment.  The Sellers hereby acknowledge that any breach or
threatened breach of any of the covenants contained herein would cause
irreparable harm to the Buyer and that money damages would not, alone, provide
an adequate remedy to the Buyer.  The Buyer shall have all of the rights and
remedies available under law, or in equity, to a party enforcing any such
covenants, each of such rights and remedies to be independent of the other and
severally enforceable including, but not limited to, the right to have such
covenants enforced by any court of competent jurisdiction including, but not
limited to, through temporary injunctive relief, temporary restraining order
and/or permanent injunctive relief, all without requirement for the posting or
provision of any bond or other security, which requirements being hereby
expressly waived by the Sellers, and the right to require any Seller who is a
violating party to account for, and pay over to the Buyer, all benefits derived
or received by such violating party as a result of any breach of such covenant.
No Seller who is a violating party shall raise as a defense to the granting of
any such relief that the Person requesting any such relief has an adequate
remedy at law.  Each of the Sellers acknowledges and agrees that the covenants
set forth herein are reasonable in duration and scope and in all other respects.
If any court determines that any such covenants, or any part thereof, are
invalid or unenforceable the remaining covenants shall not thereby be affected
and they shall be given full effect, without regard to the invalid portions.  If
any court determines that all, or any part of, the covenants contained herein
are unenforceable, because of the duration or scope of such provision, such
court is requested to reduce the duration or scope of such provision, as the
case may be, so that, in its reduced form, such provisions shall then be
enforceable.  The Sellers intend to and do hereby confer jurisdiction to enforce
the covenants contained herein upon the courts of any jurisdiction within the
United States.  If the courts of any one or more of such jurisdictions hold such
covenants unenforceable by reason of the breadth of their scope, or otherwise,
it is the intention of the parties that such determination not preclude, or in
any way affect, the right of the Company or the Buyer to the relief provided
above in the courts of any other jurisdiction within the United States as to
breaches of such covenant in such other respective jurisdictions, such covenants
as they relate to each jurisdiction being, for this purpose, severable and
independent covenants.  Nothing contained herein shall preclude any party hereto
from owning less than 1% of the issued and outstanding capital stock
<PAGE>

                                      -33-

of any corporation whose shares are listed for trading on the New York Stock
Exchange, American Stock Exchange or NASDAQ National Market.

     6.6. Non-Solicitation.
          ----------------

     (a)  From and after the Closing, and for the next succeeding two (2) years,
each of the Sellers agree with the Buyer that it will not, either alone or
jointly with any Person or as manager, agent or consultant of any Person
directly or indirectly engage, employ, solicit or contact with a view to the
engagement or employment by any Person, any employee, officer or manager of the
Company or the Buyer or of any customer or current prospect of the Buyer and the
Company.

     (b)  While the restrictions in (a) above are considered by Buyer, the
Company and the Sellers to be reasonable in all the circumstances, it is agreed
that if any one or more of such restrictions, taken by itself or themselves
together, be adjudged to go beyond what is reasonable in all the circumstances
for the protection of Buyer and the Company's legitimate interest but would be
adjudged reasonable if any particular restriction was deleted, restricted or
limited in any particular manner, then the said restrictions shall apply with
such deletions, restrictions or limitations, as the case may be.

     6.7. Pooling.  (a) Buyer, Corum, the Company and each of the Sellers shall
          -------
use all reasonable efforts and shall cooperate fully and shall take all actions
as are reasonably necessary to allow the acquisition of the Company by Buyer as
contemplated by this Agreement to be accounted for as a "pooling of interests"
in accordance with generally accepted accounting principles and applicable
accounting pronouncements of the SEC.

          (b)  Each Seller and any other person who may be considered an
"affiliate" of the Company, as such term is used in Rule 145 under the
Securities Act and applicable accounting pronouncements of the SEC (the "Company
                                                                         -------
Affiliates") and Corum hereby agrees that he or it, as applicable, (i) has not
- ----------
made and will not sell, exchange, transfer, pledge, dispose or otherwise reduce
his or its risk relative to any shares of securities of the Company in the 30-
day period prior to the Closing, and (ii) will not sell, exchange, transfer,
pledge, dispose or otherwise reduce his or its risk relative to any of the
shares of Buyer Stock to be received by such person after the Closing until
Buyer shall have publicly released a report including the combined financial
results of Buyer and the Company for a period of at least 30 days of combined
operations of Buyer and the Company.

     7.1. Survival.  The representations and warranties of the parties hereto
          --------
contained in this Agreement or in any certificate or other writing delivered
pursuant hereto or in connection herewith shall survive the Closing for a period
of one (1) year.  Notwithstanding the preceding sentence, any representation or

survive the time at which it would otherwise terminate pursuant to the preceding
sentence, if notice of the inaccuracy or breach thereof giving rise to such
right to

indemnity shall have been given to the party against whom such indemnity may be
sought prior to such time; provided, however that such representation or
warranty shall survive until, but only for the purposes of, the resolution of
such claim. The covenants and agreements of the parties hereto contained in
this Agreement, any Collateral Document or in any certificate or other writing
delivered pursuant hereto shall survive the Closing irrespective of the passage
of time.

to perform any of the covenants or agreements set forth in Sections 6.5 and 6.6
of this Agreement;

     For purposes of this Agreement, "Damages" shall mean and include any and
                                      -------
all debts, obligations and other liabilities (whether absolute, accrued,
contingent, fixed or otherwise, or whether known or unknown, or due or to become
due or otherwise), monetary damages, fines, fees, penalties, interest
obligations, deficiencies, losses and expenses (including without limitation
amounts paid in settlement, interest, court costs, costs of investigators, fees
and expenses of attorneys, accountants, financial advisors and other experts,
and other expenses of litigation) incurred or suffered by an Indemnified Person
(as hereinafter defined) or any affiliates thereof.

     7.2.2.  Buyer shall indemnify the Sellers, and their employees, officers,
directors and shareholders (the "Seller Persons") and Corum, and its employees,

                                      -35-

     7.3.   Method of Asserting Claims.
            --------------------------

     (a)     The Indemnified Person shall give prompt written notification to
the Indemnifying Party of the commencement of any action, suit or proceeding
relating to a third party claim for which the indemnification pursuant to this
Article VII may be sought (the "Third Party Claim"), provided, however, that the
                                -----------------
failure to provide such notice shall not release the Indemnifying Party from any
obligations under this Article VII except to the extent such Indemnifying Party
is materially prejudiced by such failure and shall not relieve such Indemnifying
Party from any other obligation or liability that it may have to any Indemnified
Person otherwise than under this Article VII. Within 20 calendar days after
delivery of such notification, the Indemnifying Party may, upon written notice
thereof to the Indemnified Person, assume control of the defense of such Third
Party Claim with counsel reasonably satisfactory to the Indemnified Person,
provided the Indemnifying Party acknowledges in writing to the Indemnified
Person that any damages, fines, costs or other liabilities that may be assessed
against the Indemnified Person in connection with such Third Party Claim
constitute Damages for which the Indemnified Person shall be entitled to
indemnification pursuant to this Article VII. If the Indemnifying Party does not
assume control of such defense, the Indemnified Person shall control such
defense. The party not controlling the defense of such Third Party Claim may
participate therein at its own expense; provided that if the Indemnifying Party
assumes control of such defense and the Indemnified Person reasonably concludes
that the Indemnifying Party and the Indemnified Person have conflicting
interests or different defenses available with respect to such Third Party
Claim, then the reasonable fees and expenses of counsel to the Indemnified
Person shall be considered "Damages" for purposes of this Agreement. In the
event that the Indemnifying Party exercises the right to undertake any such
defense against any such Third Party Claim as provided above, the Indemnified
Person shall cooperate with the Indemnifying Party in such defense and make
available to the Indemnifying Party, at the Indemnifying Party's expense, all
witnesses, pertinent records, materials and information in the Indemnified
Person's possession or under the Indemnified Person's control relating thereto
as is reasonably required by the Indemnifying Party. Similarly, in the event the
Indemnified Person is, directly or indirectly, conducting the defense against
any such Third Party Claim, the Indemnifying Party shall cooperate with the
Indemnified Person in such defense and make available to the Indemnified Person,
at the Indemnifying Party's expense, all such witnesses, records, materials and
information in the Indemnifying Party's possession or under the Indemnifying
Party's control relating thereto as is reasonably required by the Indemnified
Person. The party controlling such defense shall keep the other party advised of
the status of such Third Party Claim and the defense thereof and shall consider
in good faith recommendations made by the other party with respect thereto. The
Indemnified Person shall not agree to any settlement of such Third Party Claim
without the prior written consent of the Indemnifying Party, which shall not be
unreasonably withheld. In addition, the Sellers shall not agree to any
settlement of Third Party Claim without the prior written consent of the
Indemnified Person, which consent shall not be unreasonably withheld.

     (b)     If a third party asserts that an Indemnified Person is liable to
such third party for a monetary or other obligation which may constitute or
result in Damages for which such Indemnified Person may be entitled to
indemnification pursuant to this Article VII, and such
<PAGE>

                                      -36-

Indemnified Person reasonably determines that it has a valid business reason to
fulfill such obligation, then (i) such Indemnified Person shall be entitled to
satisfy such obligation, without prior notice to or consent from the
Indemnifying Party, (ii) such Indemnified Person may make a claim for
indemnification pursuant to this Article VII (in accordance with the provisions
of the Escrow Agreement if the Indemnified Person is a Buyer Person), and (iii)
such Indemnified Person shall be reimbursed (in accordance with and subject to
the provisions of the Escrow Agreement if the Indemnified Person is a Buyer
Person) for any such Damages for which it is entitled to indemnification
pursuant to this Article VII.

     7.4.  Limitations; Exclusive Remedy; Maximum Indemnification.
           ------------------------------------------------------

     (a)   Notwithstanding anything to the contrary herein, except with respect
to claims based either on fraud or a breach of Section 2.10 (Taxes), (i) the
aggregate liability of the Sellers for Buyer Damages resulting from a
misrepresentation or breach of a representation or warranty under Section
7.2.1(a) of this Article VII shall not exceed the aggregate amount of the Escrow
Shares (or cash held by the Escrow Agent pursuant to the terms of the Escrow
Agreement in Escrow in replacement thereof) and the individual liability of each
Seller for Buyer Damages resulting from a misrepresentation or breach of a
representation or warranty under Section 7.2.1(a) of this Article VII shall not
exceed such Seller's pro rata amount of the Escrow Shares (or cash held by the
Escrow Agent pursuant to the terms of the Escrow Agreement in escrow in
replacement thereof), and (ii) no indemnification payment by the Sellers with
respect to any Buyer Damages otherwise payable pursuant to this Article VII
shall be payable until such time as all such Buyer Damages shall aggregate to
more than $50,000, at which time all such Buyer Damages payable under this
Article VII shall be payable. Notwithstanding anything to the contrary, except
with respect to claims based either on fraud or a breach of Section 2.10
(Taxes), the Buyer Company Persons shall seek recovery solely against, and said
recovery shall be limited to, the Escrow Shares (or cash held in escrow by the
Escrow Agent pursuant to the terms of the Escrow Agreement in replacement
thereof), including for the $50,000 "basket," with respect to, and this Article
and the Escrow Agreement shall be the exclusive remedy of Buyer Company Persons
for, claims resulting from or relating to any misrepresentation or breach of any
representation or warranty under Section 7.2.1(a) of this Article VII.

     (b)   Notwithstanding anything to the contrary herein, except with respect
to claims based on fraud, (i) the aggregate liability of the Buyer in connection
with the indemnification of the Seller Persons pursuant to this Article VII for
Damages resulting from a misrepresentation or breach of a representation or
warranty under Section 7.2.2 of this Article VII shall in no event exceed the
Fair Market Value of the Buyer Stock Shares as defined in Section 1.2, and (ii)
no indemnification payment by Buyer with respect to any Damages otherwise
payable pursuant to this Article VII shall be payable until such time as all
such Damages shall aggregate to more than $50,000, at which time all such
Damages payable under this Article VII shall be payable.

                  (iv)   furnish to each Seller and to Corum such number of
         copies of the Registration Statement and the Prospectus (including each

         public sale or other disposition of the Registrable Securities;

                  (v)    use its reasonable efforts to register or qualify the
         Registrable Securities under the state securities or "blue sky" laws of
         such jurisdictions as each Seller or Corum shall reasonably request and
         to maintain such qualification throughout the Distribution Period,
         except that Buyer shall not be required for the purpose of such
         qualification to qualify generally to transact business as a foreign
         corporation in any jurisdiction where it is not so qualified or, except
         as to matters relating to the offer and sale of the Registrable
         Securities, consent to general service of process in any such
         jurisdiction;

         notification from the Commission or any other jurisdiction as to the

         to be filed by Buyer pursuant to subsections 13(a), 13(c), 15(d), and

         qualification to file a Registration Statement;

                  (viii) During the period of time set forth in (i) above, to
         use its best efforts to maintain its quotation on the Nasdaq National
         Market or listing on a comparable national or regional exchange in
         order to provide Sellers with a market for their Buyer Common Shares.

         3.    SHAREHOLDER OBLIGATIONS. In connection with the filing of the
Registration Statement, each Seller and Corum will furnish to Buyer as
expeditiously as possible, such documents or information with respect to itself
and the proposed sale or distribution of the Registrable Securities, as is
reasonably necessary in order to assure compliance with U.S. federal and
applicable state securities laws, and as a condition to any proposed sale or
distribution of the Registrable Securities deliver to Buyer in writing

any Registration Statement, may be suspended by Buyer on the occurrence of a
Material Event.

         (b)   In the event of a suspension pursuant to paragraph (a) of this

Sellers and Corum under Section 4(a) shall be so suspended shall not exceed 60
days in the aggregate.

         (c)   Buyer shall promptly give the Sellers and Corum notice of both
the beginning and end of any suspension under subsection 4(a). The notice shall

         (d)   Notwithstanding anything herein to the contrary, any Sellers who
are employees or officers of the Buyer shall be subject to the restrictions on
sale of Registrable Securities during

connection with the registration of Registrable Securities effected by Buyer
pursuant to Section 2 hereof. Sellers of Registrable Securities registered

         6.    SALE OF REGISTRABLE SECURITIES DURING THE DISTRIBUTION PERIOD.

         The parties confirm their intention that the sale or distribution of
the Registrable Securities will be carried out in a orderly and cooperative
manner. To that end, the Sellers and Corum will periodically advise Buyer of the
nature and progress of their efforts to sell or distribute the Registrable
Securities including, without limitation, the provision to Buyer of a written
monthly report setting out any sales of Registrable Securities.

         7.    INDEMNIFICATION.

         (a)   Buyer will indemnify and hold harmless each of the Sellers, and
Corum, the officer, directors, partners, agents and employees of the Sellers and
Corum and each person, if any, who controls such Seller or Corum within the
meaning of the Securities Act, against all losses, claims, damages or
liabilities, joint or several (collectively "Claims"), to which they may become
                                             ------
subject under the Securities Act, the Exchange Act or other federal or state law
(excepting Claims related to or arising from a breach by such Sellers or Corum
of its obligations under Sections 3 or 4), in so far as the Claims (or actions
in respect thereof) arise out of or are based on (i) any untrue statement or
alleged untrue statement of any material fact contained in the Registration
Statement or any amendment or supplement thereto, or the omission or alleged
omission to state in those
<PAGE>

                                      -6-

documents a material fact required to be stated therein, or necessary to make
the statements therein, not misleading or (ii) any untrue statement or alleged
untrue statement of a material fact contained in any preliminary Prospectus or
the Prospectus or any amendment or supplement thereto, or the omission or
alleged omission to state in those documents a material fact necessary to make
the statements therein, in light of the circumstances under which they were
made, not misleading (collectively, a "Violation"), and reimburse each such
                                       ---------
Seller, officer, director, partner, agent, employee or controlling person and
Corum for any legal or other expenses reasonably incurred by them in connection
with investigating or defending any Claims; provided, however, that the
                                            --------  -------
indemnity agreement contained in this Section 7(a) shall not apply to amounts
paid in settlement of any such Claims, if such settlement is effected without
the consent of Buyer, which consent shall not be unreasonably withheld,
conditioned or delayed. This indemnity shall not apply to any Claims that arise
out of, or are based upon an untrue statement or alleged untrue statement or
omission or alleged omission made in reliance upon and in conformity with
information provided by any such Seller or Corum in writing specifically for the
purposes of filing or maintaining the effectiveness of the Registration
Statement.

         (b)   Each Seller and Corum will, severally as to himself or itself, as
the case may be, indemnify and hold harmless Buyer, each of its officers,
directors, partners, agents or employees, each person, if any, who controls
Buyer within the meaning of the Securities Act, any underwriter and any other
Seller or any of its directors, officers, partners, agents or employees or any
person who controls such Seller, and Corum or any of its directors, officers,
partners, agents or employees or any person who controls Corum against any
Claims to which Buyer or any such director, officer, partner, agent, employee,
controlling person or underwriter, or other such Seller or Corum or director,
officer, partner, agent, employee or controlling person may become subject,
under the Securities Act, the Exchange Act or other federal or state law,
insofar as such Claims arise out of or are based upon any Violation, in each
case to the extent (and only to the extent) that such Violation occurs in
reliance upon and in conformity with written information furnished by such
Seller or Corum, as applicable, expressly for use in connection with such
registration; and each such Seller or Corum, as applicable, will reimburse any
reasonable legal or other expenses reasonably incurred by Buyer or any such
director, officer, partner, agent, employee, controlling person or underwriter,
other Seller, Corum, officer, director, partner, agent, employee or controlling
person in connection with investigating or defending any such Claims.
Notwithstanding anything contained in this Agreement to the contrary, the
indemnity agreement contained in this Section 7(b) shall not apply to amounts
paid in settlement of any such Claims if such settlement is effected without the
consent of the Seller or Corum, as applicable, which consent shall not be
unreasonably withheld, conditioned or delayed; provided further, that the
                                               -------- -------
aggregate liability of each Seller or Corum in connection with any sale of
Registrable Securities pursuant to a Registration Statement in which a Violation
occurred shall be limited to such Seller"s net proceeds from the sale of
Registrable Securities pursuant to such Registration Statement.

         (c)   As soon as it becomes aware of the commencement of an action
respecting a Claim, the indemnified party shall promptly notify the indemnifying
party, although failure to notify shall not relieve the indemnifying party from
any liability to indemnify the indemnified party. Following receipt of that
notice, the indemnifying party may participate in and, to the extent it wishes
and upon giving notice to the indemnified party, assume and undertake the
defense of the action using counsel satisfactory to it. In that event, the
indemnifying party will not be liable to the indemnified party for any legal
expenses subsequently incurred by the
<PAGE>

                                      -7-

indemnified party in connection with the defense of the action, other than
reasonable costs of investigation and of liaison with the indemnifying party"s
counsel. If the defendants in any action include both the indemnified party and
the indemnifying party, and if the indemnified party reasonably concludes that
there may be reasonable defenses available to it that are different from or
additional to those available to the indemnifying party or if the interests of
the indemnified party reasonably may be deemed to be conflicting with the
interests of the indemnifying party, the indemnified party shall have the right
to select separate counsel and to assume those legal defenses and otherwise to
participate in the defense of the action, with the expenses and fees of separate
counsel and other expenses related to that participation to be reimbursed by the
indemnifying party as incurred.

         (d)   If the indemnification provided for above is held by a court of
competent jurisdiction to be unavailable, then the indemnifying party, in lieu
of such indemnification, shall contribute to the amount paid or payable by the
indemnified party in such proportion as is appropriate to reflect the relative
fault of the indemnifying party on the one hand the indemnified party on the
other hand in connection with the statements or omissions that resulted in the
Claims, as well as other equitable considerations; provided, however, that, in
                                                   --------  -------
any such case (i) neither a Seller nor Corum shall be required to contribute any
amount in excess of such Seller"s net proceeds and/or value of such Buyer Common
Shares, on the date of such sale pursuant to the registration of such shares
effected by Buyer under this Agreement, and (ii) no person or entity guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person or entity who
is not guilty of such fraudulent misrepresentation. The relative fault of the
parties shall be determined by reference to, among other things, whether the
alleged untrue statement of a material fact or omission to state a material fact
relates to information supplied by the indemnifying party or the indemnified
party and the parties" relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

         (e)   The provisions of this Section 7 shall survive the expiration or
termination of this Agreement and shall expire at the end of any applicable
limitation period.

         8.    RESTRICTIONS ON TRANSFERS OF COMMON SHARES.

         The Sellers and Corum agree and understand that the issuance of the
Registrable Securities has not been, and, except as contemplated in this
Agreement, the sale or other disposition thereof by the Sellers and Corum will
not be, registered under the Securities Act or the securities laws of any state
and that such shares may be sold or disposed of only in one or more transactions
registered under the Securities Act and, where applicable, such state laws or as
to which an exemption from the registration requirements of the Securities Act
and, where applicable, such state laws is available. The Sellers and Corum
acknowledge that, except as expressly set forth in this Agreement, the Sellers
and Corum have no right to require Buyer to cause the registration of any
Registrable Securities. The Sellers and Corum understand and agree that each
certificate representing any Registrable Securities (each, a "Certificate")
                                                              -----------
shall be subject to stop transfer instructions and shall bear the following
legend:
<PAGE>

                                      -8-

              "THE SECURITIES REPRESENTED BY THIS CERTIFICATE
              HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
              OF 1933, AS AMENDED (THE "ACT"), OR ANY APPLICABLE
              STATE OR FOREIGN SECURITIES LAWS. THESE SECURITIES
              HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A
              VIEW TO DISTRIBUTION OR RESALE, AND MAY NOT BE
              SOLD, MORTGAGED, PLEDGED, HYPOTHECATED OR OTHERWISE
              TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION
              STATEMENT FOR SUCH SECURITIES UNDER THE ACT AND ANY
              APPLICABLE STATE AND FOREIGN SECURITIES LAWS OR THE
              AVAILABILITY OF AN EXEMPTION FROM SUCH REGISTRATION
              REQUIREMENTS."

         Buyer hereby agrees that it will, upon the request of the Sellers and
Corum, eliminate any stop transfer instructions and any restrictive legend on
any certificates representing the Registrable Securities if (i) in the opinion
of counsel, which counsel and opinion (in form, scope and substance) shall be
reasonably satisfactory to Buyer, the Sellers and Corum are entitled to sell or
dispose of the Registrable Securities represented by such Certificate without
registration or (ii) such shares are being disposed of by the Sellers and Corum
under a Registration Statement pursuant to Section 2 herein and in compliance
with the Securities Act and applicable state and federal securities laws. Before
the Registration Statement is declared effective, Buyer will use reasonable
efforts to arrange for its transfer agent to automatically remove the legend and
transfer any shares disposed of by the Sellers and Corum under a Registration
Statement pursuant to Section 2 herein if a Seller and Corum and its broker
provide transfer representation documents reasonably acceptable to its transfer
agent.

                                ESCROW AGREEMENT
                                ----------------

          This Escrow Agreement is entered into as of December 30, 1999, by and
among SeaChange International, Inc., a Delaware corporation (the "Buyer"),
Digital Video Arts, Ltd., a Delaware corporation (the "Company"), the
shareholders listed on the signature pages hereto ("Sellers" and individually a
"Seller"), and State Street Bank and Trust Company (the "Escrow Agent").

          WHEREAS, pursuant to a Stock Purchase Agreement dated as of the date
hereof by and among the Buyer, Corum Group, Ltd., the Company and the Sellers
(the "Stock Purchase Agreement"), Buyer is acquiring all of the issued and
outstanding shares of the capital stock of the Company from the Sellers in
exchange for shares of the Common Stock, par value $.01 per share, of Buyer (the
"Buyer Stock");

          WHEREAS, Buyer, the Company, and certain of their respective
affiliates (the "Buyer Persons") are to be indemnified against breaches of the
Sellers' representations, warranties and agreements made in the Stock Purchase
Agreement (the "Escrow"), subject, however, to the limitations set forth in the
Stock Purchase Agreement; and

          WHEREAS, as provided for in the Stock Purchase Agreement, to provide
for the payment of such indemnification, the Sellers have agreed to permit
shares representing ten percent (10%) of the shares of the Buyer Stock (other
than the Corum Shares) issuable to them pursuant to Sections 1.2 (Consideration
and Payment) and 1.4 (Deliveries and Proceedings at the Closing) of the Stock
Purchase Agreement to be held in escrow as hereinafter provided to satisfy the
Escrow (together with any capital stock or equity interests issued by the Buyer
after the date hereof in the form of a stock dividend or recapitalization
affecting the shares of the Buyer Stock otherwise held in Escrow, the "Escrow
Shares" which together with the cash proceeds from the sale of any Escrow Shares
pursuant to Section 7 (Additional Property Subject to Escrow) hereof and held in
the escrow account established hereby, including any investment earnings
received from the investment thereof and held pursuant to Section 7 (Additional
Property Subject to Escrow) hereof, are collectively referred to as the "Escrow
Property").

          NOW, THEREFORE, in consideration of the foregoing and the mutual
promises of the parties herein contained, and other good and valuable
consideration, receipt of which is hereby acknowledged, the parties hereto,
intending to be legally bound, agree as follows:

          1.   Defined Terms.  Capitalized terms used in this Agreement and not
               -------------
otherwise defined herein shall have the meanings ascribed to them in the Stock
Purchase Agreement.

          2.   Appointment and Agreement of Escrow Agent. The Buyer, the Company
               -----------------------------------------
and the Sellers hereby appoint the Escrow Agent to serve as, and the Escrow
Agent hereby agrees to act as, escrow agent upon the terms and conditions of
this Agreement.
<PAGE>

     3.   Indemnification.  The parties agree that this Agreement shall secure
          ---------------
the right of indemnification of the Buyer and the Company from and against
damages as specified in Article VII (Indemnification) of the Stock Purchase
Agreement ("Buyer Damages") by the Sellers upon the terms and subject to the
limitations set forth in Article VII (Indemnification) of the Stock Purchase
Agreement.

     4.   Establishment of Escrow; Escrow Fund.  Promptly following the Closing,
          ------------------------------------
Buyer shall deliver to the Escrow Agent one (1) stock certificate which shall be
registered on Buyer's corporate books in the name of the Escrow Agent (or its
nominee), for the account of the Sellers in the amounts set forth on Annex A
                                                                     -------
attached hereto, which shall represent the Escrow Shares and be held in an
account designated as "Digital Escrow Account." The Digital Escrow Account is
sometimes hereinafter referred to as the Escrow Fund. All Escrow Shares shall be
held by the Escrow Agent for the benefit of the Sellers and shall not be
disposed of by the Escrow Agent except as otherwise provided herein. The name
and address of each Seller and the number of Escrow Shares held for the benefit
of each such Seller as of the date hereof is set forth on Annex A attached
                                                          -------
hereto. For purposes of this Agreement, a Seller's "Pro Rata Portion" shall
refer to the ratio of (i) the Escrow Property held for the account of a
particular Seller to (ii) the Escrow Property held for the account of all
Sellers.  All payments to the Buyer Persons from the Escrow Fund in respect of
Buyer Damages with respect to which it has been determined that such Indemnified
Parties are entitled to indemnification pursuant to this Agreement and the Stock
Purchase Agreement, if any, shall be made with respect to each Seller first,
from the Escrow Share Equivalents and the investment proceeds thereon that are
attributable to such Seller that are then held by the Escrow Agent and, second,
in the form of Buyer Stock deposited with the Escrow Agent hereunder (which
shall be valued at the Fair Market Value provided in Section 1.2 (Consideration
and Payment) of the Stock Purchase Agreement, which Fair Market Value shall be
certified in writing to the Escrow Agent by the Buyer and the Sellers).  After
each Seller's account hereunder has been established, all debits thereto
required hereunder shall be made in accordance with each such Seller's Pro Rata
Portion of each indemnification payment made from the Escrow Fund in accordance
with the terms of this Agreement, provided, however, that to the extent that the
indemnification payment relates to the liability of a particular Seller for a
breach of any of the representations and warranties contained in Article II
(Representations and Warranties of the Company and the Sellers) or IIA
(Additional Representations and Warranties of Sellers) of the Stock Purchase
Agreement in each case as specified in the related Claim Notice, then such
debits shall be made against such Sellers' account and the Pro Rata Portions of
each Seller shall be adjusted accordingly. The respective interests of the
Sellers in the Escrow Fund shall not be transferable or assignable, other than
(i) by operation of law or (ii) in connection with the assignment or transfer to
a partner, stockholder, member, affiliate or family member of the Seller, or to
any trust or limited or general partnership for the benefit of any such family
member of the Seller, provided each such transferee agrees in a written
instrument delivered to the Escrow Agent and the Buyer to be bound by the
provisions of this Agreement as a Seller.  Notice of any assignment or transfer
shall be given to the Escrow Agent and the Buyer, and no assignment or transfer
shall be valid until such notice is given.
<PAGE>

     5.   Voting Rights.  In the event of a meeting or written action of
          -------------
stockholders of Buyer during the term of this Escrow Agreement, the Escrow Agent
shall send to the Sellers copies of any notices, proxies and proxy material
received by it in connection with such meeting. Buyer hereby undertakes to
independently furnish copies of all such notices, proxies and proxy materials
directly to each Seller and to cooperate with the Sellers and the Escrow Agent
to facilitate the exercise by Sellers of voting rights in the Escrow Shares.
Upon request of the Sellers, the Escrow Agent shall execute and deliver a proxy
authorizing them to vote the whole number of their Escrow Shares.

     6.   Dividends and Distributions.  All dividends and other distributions
          ---------------------------
or rights paid on or granted with respect to the Escrow Shares shall be added to
the related Seller's Pro Rata Portion of the Escrow Fund in accordance with
Section 4 (Establishment of Escrow; Escrow Fund) and shall be held hereunder
upon the same terms as the Escrow Shares. Any cash in the Escrow Fund resulting
from dividends or distributions with respect to the Escrow Shares shall be
invested by the Escrow Agent in the State Street Insured Money Market Account,
and any interest or earnings thereon shall be allocated for tax purposes to the
Sellers in accordance with their respective interests in the related Escrow
Shares.

     7.   Additional Property Subject to Escrow.
          -------------------------------------

          (a)  At any time beginning on the date that the post-closing results
of at least thirty (30) days combined operations of Buyer and the Company have
been published (the "Permitted Sale Date"), and subject to any restrictions,
                     -------------------
if any, on resale arising under federal or state securities laws, a Seller may
effect a sale of any or all of such Seller's Pro Rata Portion of the Escrow
Shares by written direction given to the Escrow Agent provided that: (A) such
Seller shall certify to the Escrow Agent that the Permitted Sale Date has
passed, (B) the written directions given to the Escrow Agent by such Seller
shall be subject to Section 7(d) below, and (C) the net proceeds of such sale of
Escrow Shares shall be paid to the Escrow Agent and deposited into the Escrow
Fund and become part of the Escrow Property. All related transaction charges and
out-of-pocket expenses (or reasonably estimated allocable portions thereof)
directly associated with a sale of Escrow Shares shall be paid from the proceeds
of the sale. The Sellers may direct the sales of Escrow Shares pursuant to this
Section 7(a) at any time or times after the Permitted Sale Date.

          (b)  Net proceeds of the sale of any Escrow Shares deposited into the
Escrow Account pursuant to Section 7(a) hereof shall be retained in the Escrow
Fund and invested by the Escrow Agent in the State Street Insured Money Market
Account. Such proceeds and any interest or earnings thereon shall be allocated
(including for tax purposes) to the portion of the Escrow Fund attributable to
the individual Seller directing such sale.

          (c)  Any sale direction given by a Seller pursuant to Section 7(a)
above shall: (A) specify the number of Escrow Shares to be sold, (B) if
applicable, identify the brokerage firm such Seller requests the Escrow Agent to
use, and (C) set forth all necessary instructions (including stop loss or
minimum price per share instructions) as necessary to satisfy the required net
proceeds per share requirements set forth in clause (C) of Section 7(a) above,
together with
<PAGE>

any other instruction as the Escrow Agent reasonably may require in order to
carry out the sale. The Escrow Agent shall be entitled to rely conclusively, in
good faith, upon such direction and shall be under no obligation to evaluate or
exercise any judgment with respect to any such instruction received from such
Seller.

          (d)  The Escrow Agent shall have no responsibility in connection with
a sale other than to make delivery of the Escrow Shares in accordance with the
instructions received from such Seller and to deposit into the Escrow Account
the net sale proceeds received from the sale. The Escrow Agent shall have no
liability for any actions or omissions of any brokerage firm, if any, included
in such instructions, and shall have no liability for the price or execution
achieved (other than resulting from its own gross negligence or willful
misconduct). Without limiting the foregoing, the Sellers acknowledge that (A)
the Escrow Shares may need to be sent to a transfer agent to be reissued in
saleable form, (B) the Escrow Shares may contain or be subject to transfer
restrictions that may limit their marketability and impose restrictions upon the
number or types of purchasers to whom they can be offered or sold, (C) the
Escrow Agent shall have no liability for any failure or delay (or any price
change during any such delay) on the part of a Seller or any transfer agent, or
caused by any necessary registration or delivery procedures, or compliance with
any applicable transfer restrictions, in connection with the transfer of such
Escrow Shares, and (D) the Escrow Agent shall have no liability if the actual
net proceeds received per share are less than the Fair Market Value provided in
Section 1.2 (Consideration and Payment) of the Stock Purchase Agreement.

          (e)  In any agreement entered into by the Escrow Agent with any
brokerage firm (which may be affiliated with the Escrow Agent, as selected by
the Escrow Agent without liability on its part, taking into consideration the
brokerage firm requested by a Seller as provided above), pursuant to Sections
7(c) and (d), if applicable, the Escrow Agent shall be entitled to enter into
such agreement on terms providing that the brokerage firm shall use its "best
efforts" to effect a sale. The Escrow Agent shall be indemnified by the Sellers
hereunder for any costs, expenses and risks associated therewith or arising
thereunder (other than resulting from its own gross negligence or willful
misconduct).

          (f)  In addition to any applicable fees set forth on the fee schedule
attached hereto as Attachment B, the net sale proceeds of any sale of Escrow
Shares received by the Escrow Agent shall be subject to a $500.00 (per sale
order) fee payable to the Escrow Agent from such sale proceeds for the proration
of the net sales price, individual 1099-B reporting and related administration
(the "Sales Administration Fee").

          (g)  For purposes of this Agreement, an "Escrow Share Equivalent"
shall refer to the net sale proceeds from the sale of a share of Buyer Stock
previously held in the Escrow Fund and sold pursuant to this Section 7. The
parties agree that the calculation of Escrow Share Equivalent amounts shall be
made with respect to each Seller on a first in first out basis.

     8.   Cash Proceeds.  With respect to any net sale proceeds of any sale of
          -------------
Escrow Shares held in the Escrow Account from time to time:
<PAGE>

          (i)    Tax Reporting. For tax reporting purposes, all income or gain
                 -------------
                 from the sale of Escrow Shares in any tax year shall be
                 reported as allocable to the Sellers directing such sales
                 according to their relative ownership of Escrow Share
                 Equivalents;

          (ii)   Certification of Taxpayer Identification Number.  The Sellers
                 -----------------------------------------------
                 shall provide a certified tax identification number by signing
                 and returning a Form W-9 (or Form W-8, in case of non-U.S.
                 persons) to the Escrow Agent prior to the earlier of 30 days
                 after the date of this Agreement or the date on which any sale
                 proceeds held as part of the Escrow Property is credited to the
                 Escrow Account. The Sellers understand that, in the event their
                 tax identification numbers are not certified to the Escrow
                 Agent, the Internal Revenue Code, as amended from time to time,
                 may require the withholding of a portion of any gain or other
                 income related to the sale of Escrow Shares.

          (iii)  Tax Indemnification.  The Sellers agree, jointly and severally,
                 -------------------
                 (1) to assume any and all obligations imposed now or hereafter
                 by any applicable tax law with respect to any payment or
                 distribution of the Escrow Property or performance of other
                 activities under this Agreement, withholding and other taxes,
                 assessments or other governmental reporting that may be
                 required under any laws or regulations that may be applicable
                 in connection with its acting as Escrow Agent under the
                 Agreement, (2) to instruct the Escrow Agent in writing with
                 respect to the Escrow Agent's responsibility for withholding
                 and other taxes, assessments or other governmental charges, and
                 to instruct the Escrow Agent with respect to any certifications
                 and governmental reporting that may be required under any laws
                 or regulations that may be applicable in connection with its
                 acting as Escrow Agent under this Agreement and (3) to
                 indemnify and hold the Escrow Agent harmless from any liability
                 or obligation on account of taxes, assessments, additions for
                 late payment, interest, penalties, expenses and other
                 governmental charges that may be assessed or asserted against
                 the Escrow Agent in connection with or relating to any payment
                 made or other activities performed under the terms of this
                 Agreement, including without limitation any liability for the
                 withholding or deduction of (or the failure to withhold or
                 deduct) the same, and any liability for failure to obtain
                 proper certifications or to report properly to governmental
                 authorities in connection with this Agreement, including costs
                 and expenses (including reasonable legal fees and expenses),
                 interest and penalties. The foregoing indemnification and
                 agreement to hold harmless shall survive the termination of
                 this Agreement.

     9.   Administration of Escrow Fund.  The Escrow Agent shall administer the
          -----------------------------
Escrow Fund as follows:
<PAGE>

          (a)  If a Buyer Person has incurred or suffered Buyer Damages for
which it is entitled to indemnification under Article VII (Indemnification) of
the Stock Purchase Agreement, the Buyer Person shall, prior to 5:00 p.m. Boston
time on December 30, 2000 in connection with claims made pursuant to the Escrow
(the "Termination Date") deliver written notice of such claim (a "Claim Notice")
to the Escrow Agent and those Sellers obligated to indemnify the Buyer Person
from and against such Buyer Damages pursuant to Article VII (Indemnification) of
the Stock Purchase Agreement. Each Claim Notice shall state the amount of
claimed Buyer Damages (the "Claimed Amount") and the basis for such claim.

          (b)  Within 20 days after delivery of a Claim Notice, the Sellers so
notified shall deliver to the Buyer Person, with a copy to the Escrow Agent, a
written response (the "Response Notice") in which such Sellers shall: (i) agree
that all of the Claimed Amount may be released from the Escrow Fund to the Buyer
Person, (ii) agree that part, but not all, of the Claimed Amount (the "Agreed
Amount") may be released from the Escrow Fund to the Buyer Person or (iii)
contest that any of the Claimed Amount may be released from the Escrow Fund to
the Buyer Person. Any of the Sellers may contest the release from escrow of all
or a portion of the Claimed Amount only based upon a good faith belief that all
or such portion of the Claimed Amount does not constitute Buyer Damages for
which the Buyer Person is entitled to indemnification under Article VII
(Indemnification) of the Stock Purchase Agreement. If no Response Notice is
delivered by such Sellers and received by the Escrow Agent within such 20-day
period, such Sellers shall be deemed to have agreed that all of the Claimed
Amount may be released to the Buyer Person from the Escrow Fund.

          (c)  If the Sellers in the Response Notice unanimously agree (or are
deemed to have agreed) that all of the Claimed Amount may be released from the
Escrow Fund to the Buyer Person, the Escrow Agent shall promptly be given
written instructions from the Buyer and the Sellers to disburse to the Buyer
Person from the Escrow Fund an amount equal to the Claimed Amount (or such
lesser amount as is then held in the Escrow Fund) and the Escrow Agent shall
follow such written instructions and shall retain the balance, if any, in the
Escrow Fund.

          (d)  If the Sellers in the Response Notice agree that part, but not
all, of the Claimed Amount may be released from the Escrow Fund to the Buyer
Person, the Escrow Agent shall promptly be given written instructions from the
Buyer and the Sellers to disburse to the Buyer Person from the Escrow Fund an
amount equal to the Agreed Amount set forth in such Response Notice (or such
lesser amount as is then held in the Escrow Fund) and the Escrow Agent shall
follow such written instructions and shall retain the balance, if any, in the
Escrow Fund.

          (e)  If the Escrow Agent receives instructions pursuant to this
Section 9 to release all or a portion of the Claimed Amount, such distribution
(the "Distributable Amount") shall with respect to each Seller, be made:

          (i)  first from any cash attributable to the Seller that is then held
               in the Escrow Account, provided, however, that the actual amount
               of such Distributable Amount shall be equal to the amount of such
               cash then held in the Escrow
<PAGE>

               Fund received from the proceeds of the sale of that number of
               Escrow Shares having a Fair Market Value (as defined in Section
               1.2 (Consideration and Payment) of the Stock Purchase Agreement)
               and the investment earnings then held in the Escrow Account from
               the investment of such cash proceeds, with such cash amount
               deemed equal to such Distributable Amount (notwithstanding that
               the actual amount of such cash proceeds may be more than, or less
               than, the Distributable Amount); and

          (ii) thereafter be made from that number of Escrow Shares having a
               Fair Market Value (as defined in Section 1.2 (Consideration and
               Payment) of the Stock Purchase Agreement) equal to such
               Distributable Amount not otherwise satisfied pursuant to
               subsection (i) above.

To the extent required to satisfy the release of the Claimed Amount or Agreed
Amount, as applicable, the Escrow Agent shall deliver, as soon as practicable,
to Buyer's transfer agent (the "Transfer Agent") the Escrow Shares in exchange
for a new stock certificate representing a number of shares of Buyer Stock
(which will remain Escrow Shares) equal to the number of Escrow Shares
previously held by the Escrow Agent, less the number of Escrow Shares having a
Fair Market Value (as defined in Section 1.2 (Consideration and Payment) of the
Stock Purchase Agreement) equal to the Claimed Amount or the Agreed Amount, as
the case may be, and not otherwise satisfied by a cash payment in the manner
contemplated in this Section 9. Subject to the limitation set forth in Section 4
(Establishment of Escrow; Escrow Fund) hereto, upon any distribution of Escrow
Property to Buyer in satisfaction of a Claim Notice by the Escrow Agent, the
amount of Escrow Property held for the account of each Seller will be reduced by
its Pro Rata Portion of the Escrow Property distributed to satisfy the Claim
Notice. Any fractional interests will be carried forward until the distribution
of Escrow Property to the Sellers, at which time fractional interests will be
rounded in the discretion of Buyer.

          (f)  If any of the Sellers in the Response Notice contest the release
of all or part of the Claimed Amount (the "Contested Amount"), the matter shall
be settled by binding arbitration in Boston, Massachusetts. All claims shall be
settled by three arbitrators in accordance with the Commercial Arbitration Rules
then in effect of the American Arbitration Association (the "AAA Rules"). Such
Sellers and the Buyer Person shall each designate one arbitrator within 15 days
of the delivery of the Sellers' Response Notice contesting the Claimed Amount.
The Sellers and the Buyer Person shall cause such designated arbitrators
mutually to agree upon and to designate a third arbitrator; provided, however,
that (i) failing such agreement within 45 days of delivery of the Sellers'
Response Notice, the third arbitrator shall be appointed in accordance with the
AAA Rules and (ii) if either the Sellers or the Buyer Person fail to timely
designate an arbitrator, the dispute shall be resolved by the one arbitrator
timely designated. Such Sellers and the Buyer Person shall pay the fees and
expenses of their respectively designated arbitrators and shall bear equally the
fees and expenses of the third arbitrator. The Sellers and the Buyer Person
shall cause the arbitrators to decide the matter to be arbitrated pursuant
hereto within 60 days after the appointment of the last arbitrator. The
arbitrators' decision shall relate solely to whether the Buyer Person is
entitled to receive the Contested
<PAGE>

Amount (or a portion thereof) pursuant to the applicable terms of the Stock
Purchase Agreement and this Agreement. The final decision of the majority of the
arbitrators shall be furnished to the Sellers, the Buyer Person and the Escrow
Agent in writing and shall constitute a conclusive determination of the issue in
question, binding upon such Sellers, the Buyer Person and the Escrow Agent and
shall not be contested by any of them. Such decision may be used in a court of
law only for the purpose of seeking enforcement of the arbitrators' award. After
delivery of a Response Notice that the Claimed Amount is contested by such
Sellers, the Escrow Agent shall continue to hold in the Escrow Fund an amount
sufficient to cover the Contested Amount (up to the amount then available in the
Escrow Fund), notwithstanding the occurrence of the Termination Date, until (i)
delivery of a copy of a settlement agreement executed by the Buyer Person and
such Sellers setting forth instructions to the Escrow Agent as to the
disbursements, if any, that shall be made with respect to the Contested Amount
or (ii) delivery of a copy of the final award of the majority of the arbitrators
setting forth instructions to the Escrow Agent as to the disbursements, if any,
that shall be made with respect to the Contested Amount. The Escrow Agent shall
thereupon disburse amounts from the Escrow Fund (to the extent such amounts are
then held in the Escrow Fund) to the Buyer Person in accordance with such
agreement or instructions.

     10.  Release of Escrow Fund.
          ----------------------

          Promptly after the Termination Date, the Escrow Agent shall, upon
receipt of written instructions signed jointly by the Buyer and the Sellers,
deliver the stock certificate representing the Escrow Shares to the Transfer
Agent in exchange for:

     (A)  stock certificates for and in the name of each Seller representing
     each Seller's Pro Rata Portion of the Escrow Shares then held in escrow to
     the extent such Pro Rata Portion is attributable to Escrow Shares and not
     Escrow Share Equivalents or investment proceeds thereon;

     (B)  if applicable, a new stock certificate in the name of the Escrow Agent
     representing the aggregate number of Escrow Shares as to which Claim
     Notices are outstanding and not resolved.

     Upon receipt of such stock certificates from the Transfer Agent, the Escrow
Agent will promptly deliver (i) such stock certificates for and in the name of
the Sellers and (ii) a check payable to a Seller representing that cash balance
held by the Escrow Agent attributable to such Seller including Escrow Share
Equivalents and any other Escrow Property at such address as each Seller shall
direct. Buyer shall take its best efforts to cause the Transfer Agent to deliver
such certificates to the Sellers in the manner provided for herein.

     Notwithstanding the foregoing, if a Buyer Person has previously given a
Claim Notice relating to the Escrow which has not then been resolved in
accordance with Section 9 (Administration of Escrow Fund), the Escrow Agent
shall direct the Transfer Agent to reduce pro rata the number of shares and the
amount of the cash payment otherwise payable to the Sellers pursuant to this
Section 10 such that the Escrow Agent retains in escrow after the Termination
<PAGE>

Date an amount sufficient to cover the Claimed Amount which has not then been
resolved.  Once all remaining indemnification claims under Article VII
(Indemnification) of the Stock Purchase Agreement have been resolved, the Escrow
Agent shall distribute, if any, the remaining Escrow Shares, Escrow Share
Equivalents, Escrow Property and cash held by the Escrow Agent in the manner
such distribution would otherwise have been made pursuant to this Section 10 had
such Claimed Amount that remained unresolved at the Termination date been
resolved prior to the Termination Date.

     11.  Termination.  Unless sooner terminated by mutual written agreement of
          -----------
the Buyer and the Escrow Agent, this Agreement shall terminate upon the later of
the Termination Date or the distribution of all of the Escrow Shares in
accordance with the terms of this Agreement.

     12.  Fees and Expenses.  Except as otherwise set forth in Section 7(a) and
          -----------------
(f) hereof, Buyer agrees to pay the Escrow Agent's reasonable expenses incurred
in connection with its acceptance of this Agreement and performance of the
services required hereunder.

     13.  Duties and Responsibilities of Escrow Agent.
          -------------------------------------------

          (a)  The Buyer and the Sellers acknowledge and agree that the Escrow
Agent (i) shall not be responsible for any of the agreements referred to herein
but shall be obligated only for the performance of such duties as are
specifically set forth in this Agreement; (ii) shall not be obligated to take
any legal or other action hereunder which might in its judgment involve any
expense or liability unless it shall have been furnished with acceptable
indemnification; (iii) may rely on and shall be protected in acting or
refraining from acting upon any written notice, instruction, instrument,
statement, request or document furnished to it hereunder and believed by it to
be genuine and to have been signed or presented by the proper person, and shall
have no responsibility for determining the accuracy thereof, and (iv) may
consult counsel satisfactory to it, including in-house counsel, and the opinion
of such counsel shall be full and complete authorization and protection in
respect of any action taken, suffered or omitted by it hereunder in good faith
and in accordance with the opinion of such counsel.

          (b)  Neither the Escrow Agent nor any of its directors, officers or
employees shall be liable to anyone for any action taken or omitted to be taken
by it or any of its directors, officers or employees hereunder except in the
case of gross negligence or willful misconduct.  The Buyer and the Sellers,
jointly and severally, covenant and agree to indemnify the Escrow Agent and hold
it harmless without limitation from and against any loss, liability or expense
of any nature incurred by the Escrow Agent arising out of or in connection with
this Agreement or with the administration of its duties hereunder, including but
not limited to legal fees and other costs and expenses of defending or preparing
to defend against any claim or liability in the premises, unless such loss,
liability or expense shall be caused by the Escrow Agent's willful misconduct or
gross negligence.  In no event shall the Escrow Agent be liable for indirect,
special or consequential damages.

          (c)  Buyer and the Sellers, jointly and severally, agree to indemnify
and hold the Escrow Agent harmless from and against any taxes, additions for
late payment, interest,
<PAGE>

penalties and other expenses, that may be assessed against the Escrow Agent on
any payment of amounts under this Agreement. Buyer and the Sellers undertake to
instruct the Escrow Agent in writing with respect to the Escrow Agent's
responsibility for withholding and other taxes, assessments or other
governmental charges, certifications and governmental reporting in connection
with its acting as Escrow Agent under this Agreement. Buyer and the Sellers,
jointly and severally, agree to indemnify and hold the Escrow Agent harmless
from any liability on account of taxes, assessments or other governmental
charges, including without limitation, the withholding or deduction or the
failure to withhold or deduct same, and any liability for failure to obtain
proper certifications or to properly report to governmental authorities, to
which the Escrow Agent may be or become subject in connection with or which
arises out of this Agreement, including costs and expenses (including reasonable
attorneys' fees), interest and penalties. The provisions of paragraph (b) and
(c) shall survive the termination of this Agreement.

     14.  Resignation of Escrow Agent.  The Escrow Agent may at any time resign
          ---------------------------
as Escrow Agent hereunder by giving sixty (60) days' prior written notice of
resignation to the Buyer and the Sellers and thereafter shall deliver the Escrow
Shares to such substitute Escrow Agent as Buyer and Sellers shall jointly direct
in writing.  If such direction to deliver a substitute Escrow Agent is not
received by the Escrow Agent within sixty (60) days after mailing such notice of
registration, the Escrow Agent may apply to a court of competent jurisdiction
for appointment of a successor escrow agent.

     15.  Successors and Assigns.  This Agreement shall inure to the benefit of
          ----------------------
and be binding upon the successors, assigns, heirs and personal representatives
of the parties hereto.  No party may assign its rights or delegate its duties
hereunder without the prior written consent of the other parties hereto.

     16.  Force Majeure.  Neither the Buyer nor the Sellers nor Escrow Agent
          -------------
shall be responsible for delays or failures in performance resulting from acts
beyond its control.  Such acts shall include but not be limited to acts of God,
strikes, lockouts, riots, acts of war, epidemics, governmental regulations
superimposed after the fact, fire, communication line failures, computer
viruses, power failures, earthquakes or other natural disasters.
