                                ESCROW AGREEMENT


     This ESCROW AGREEMENT (the 'AGREEMENT') is entered into as of December 30,
1998 (the 'EFFECTIVE DATE'), by and among At Home Corporation, a Delaware
corporation ('ACQUIRER'), Charles M. Hazard, Jr., as representative (the
'REPRESENTATIVE') of all of the holders of capital stock (the 'STOCKHOLDERS') of
Narrative Communications Corp., a Delaware corporation ('TARGET'), and State
Street Bank and Trust Company of California, N.A., as Escrow Agent (the 'ESCROW
AGENT').

     WHEREAS, Acquirer, Target and Transitory Corporation, a Delaware
corporation and wholly owned subsidiary of Acquirer ('MERGER SUB'), have entered
into an Agreement and Plan of Merger (the 'PLAN') dated as of December 17, 1998,
pursuant to which Merger Sub will merge with and into Target in a reverse
triangular merger (the 'MERGER'), with Target to be the surviving corporation of
the Merger.  Capitalized terms used in this Agreement and not otherwise defined
herein, including without limitation 'EFFECTIVE TIME', 'EXCHANGE AGENT',
'EXCHANGE SHARES', 'TOTAL EXCHANGE SHARES' and 'TOTAL TARGET SHARES', shall have
the meanings given to such terms in the Plan;

     WHEREAS, Section 2.4 of the Plan provides that, at the Effective Time,
Acquirer will be entitled to withhold from the Stockholders a certain percentage
of the shares of Acquirer Series A Common Stock issuable to the Stockholders at
the Effective Time for the purpose of securing the Stockholders' indemnification
obligations to Acquirer and the other Indemnified Persons pursuant to the terms
and conditions set forth in Article 11 of the Plan and in this Agreement;

     WHEREAS, the Stockholders and the Representative are entering into this
Agreement as a material inducement and consideration for Acquirer to enter into
the Plan and to consummate the transactions contemplated therein and as a
material inducement and condition precedent to consummation of the Merger; and

     WHEREAS, the parties desire to set forth in this Agreement the terms and
conditions pursuant to which the Escrow Shares shall be deposited in, held in
and delivered from an escrow account.

     NOW, THEREFORE, in consideration of the facts stated in the foregoing
recitals and the mutual promises hereinafter set forth, the parties hereby agree
as follows: 

 
  1.  ESCROW AND INDEMNIFICATION

      1.1  Escrow.
           ------ 

           (a) Definitions of Primary Terms.
               ---------------------------- 

               (i)   The term 'ESCROW SHARES' is defined as the Exchange Shares
that Acquirer shall withhold from the Stockholders, which shall consist of a
percentage (the 'ESCROW PERCENTAGE') of the Exchange Shares to be issued to all
Stockholders after the Effective Time and upon the surrender of their Target
Certificates, rounded down to the nearest whole number of shares. The Escrow
Percentage shall be expressed as a fraction, the numerator of which is 10% of
the Total Exchange Shares (defined in Section 2.2(a)(ii)(B) of the Plan) and the
denominator of which is the number of Exchange Shares actually issuable in the
Merger to the Stockholders after the Effective Time and upon the surrender of
their Target Certificates. The term Escrow Shares shall also refer to Additional
Escrow Shares (defined in Section 2.1(b), although the Additional Escrow Shares
may, in certain instances, be referred to separately in this Agreement) and the
stock certificates representing the Escrow Shares and Additional Escrow Shares,
when appropriate.

               (ii)  The term 'ESCROW PERIOD' is defined as that time period
beginning at the Effective Time and ending on the 'RELEASE DATE', which shall be
ten (10) business days after publication of audited consolidated financial
statements of Acquirer for the fiscal year ended December 31, 1999, but in any
event no later than March 31, 2000.

           (b) Deposit of Escrow Shares.  On the Closing Date, Acquirer will 
               ------------------------
deposit with the Exchange Agent the Exchange Shares, including shares to be
subsequently held in escrow. The Exchange Agent will give the Escrow Agent
prompt written notice of the Closing Date and Effective Time of the Merger.
Promptly after the Effective Time, the Exchange Agent will issue to the Escrow
Agent the Escrow Shares to be withheld from the Stockholders upon the surrender
of their Target Certificates, each registered in the name of the applicable
Stockholder.

           (c) Delivery of Stock Powers.  Promptly after the Effective Time, 
               ------------------------
but in any event within ten (10) business days after the Effective Time, each
Stockholder will deliver to the Escrow Agent a duly endorsed stock power (a
'STOCK POWER') substantially in the form attached as Exhibit A. In the event any
                                                     ---------         
Additional Escrow Shares (defined in Section 2.1(b)) are issued, or if the
Escrow Agent reasonably requires an additional Stock Power(s) to effect a
transfer, each Stockholder will, upon request, promptly execute and deliver an
additional Stock Power to the Escrow Agent.

           (d) Legends.  Stock certificates representing Escrow Shares will
               -------
(until they are released to the Stockholders or Acquirer in accordance with this
Agreement) bear the following legend indicating that they are subject to this
Agreement:

                                       2

 
     'THE SECURITIES REPRESENTED HEREBY MAY BE OFFERED, SOLD OR
     OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED ONLY IN ACCORDANCE
     WITH THE TERMS OF AN ESCROW AGREEMENT AMONG THE ISSUER, THE
     HOLDER THEREOF AND STATE STREET BANK AND TRUST COMPANY OF
     CALIFORNIA, N.A. A COPY OF SUCH AGREEMENT IS ON FILE AT THE
     PRINCIPAL OFFICE OF THE ISSUER.'

          1.2  Indemnification.  Acquirer and the other Indemnified Persons are
               ---------------                                                 
entitled to be indemnified by the Stockholders pursuant to the terms of Article
11 of the Plan against any Target Damages during the Escrow Period.  All claims
for Target Damages under Article 11 of the Plan must be initiated prior to the
expiration of the Escrow Period.  Each of the Stockholders has agreed to the use
of the Escrow Shares as collateral for these indemnity obligations, subject to
the terms and limitations set forth in Article 11 of the Plan and in this
Agreement.

     2.   OWNERSHIP INTERESTS IN AND RELEASE OF
          THE ESCROW SHARES

          2.1  Stockholders' Interests in the Escrow Shares.
               -------------------------------------------- 

               (a) Individual Stockholders' Interests. The Escrow Shares shall
                   ----------------------------------
be evidenced by certificates issued in the name of each Stockholder.  All of the
Escrow Shares shall be deemed to be issued and outstanding capital stock of
Acquirer.

               (b) Dividends. If Acquirer declares any cash dividends, dividends
                   ---------
payable in other property or other distributions of any kind with respect to
Escrow Shares held by the Escrow Agent, Acquirer will issue such distributions
directly to the Stockholders. Stock dividends that are issued in order to effect
a stock split of Acquirer's Series A Common Stock on Escrow Shares declared
during the Escrow Period ('ADDITIONAL ESCROW SHARES') will be delivered promptly
to the Escrow Agent, held in escrow and distributed to the Stockholders in the
same manner and in the same proportions as the Escrow Shares. For all purposes
of this Agreement, the Additional Escrow Shares will be treated the same as the
Escrow Shares. Unless and until the Escrow Agent receives certificates
representing Additional Escrow Shares, it may assume without inquiry that no
Additional Escrow Shares have been, or are required to be, issued and that the
stock certificates that the Escrow Agent possesses represent all of the Escrow
Shares.

               (c) Voting and Other Rights of Ownership. While the Escrow Shares
                   ------------------------------------
remain in the possession of the Escrow Agent, each Stockholder beneficially
owning Escrow Shares will retain and will be able to exercise with respect to
such Escrow Shares: (i) voting rights, and (ii) all other incidents of ownership
of such Escrow Shares which are not inconsistent with the terms of this
Agreement, including the right to cause the tender of such Escrow Shares in a
tender offer for Acquirer Series A Common Stock. Acquirer, not the Escrow Agent,
will be responsible for furnishing any proxy forms or other information
generally distributed by Acquirer to its stockholders.

                                       3

 
          (d) No Transfers or Encumbrances.  Prior to the release of the Escrow
              ----------------------------                                     
Shares by the Escrow Agent and delivery to each Stockholder pursuant to Section
2.3, Stockholders may not sell, assign or otherwise transfer, nor place any
Encumbrance on, any Escrow Shares or any beneficial interest therein, except:
(i) for entity stockholders, to limited partners or members of such
Stockholders; (ii) transfers made for estate planning purposes; (iii) transfers
by operation of law or laws of descent and distribution; and (iv) in connection
with a tender offer for Acquirer's Series A Common Stock.  In the case of any
permitted transfer, the transferee will be subject to all terms and provisions
of this Agreement. Also, prior to the release of the Escrow Shares by the Escrow
Agent and delivery to each  Stockholder pursuant to Section 2.3, no Escrow
Shares nor any beneficial interest therein be taken or reached by any legal or
equitable process in satisfaction of any debt or other liability of a
Stockholder, except to satisfy such Stockholder's obligations under Article 11
of the Plan.  The Escrow Agent shall have no responsibility for determining or
enforcing compliance with this paragraph, other than by retaining possession of
the Escrow Shares.

          (e) Individual Stockholder Liability.  The maximum liability for any
              --------------------------------                                
Target Damages under Section 11.2 of the Plan is set forth in Section 11.4 of
the Plan.  Payments for finally determined Claims (defined in Section 3.1) shall
be deducted from the Escrow Shares of each Stockholder pro rata in proportion to
each Stockholder's respective percentage interest in the Escrow Shares;
provided, however, that the preceding limitation on Stockholder liability shall
not apply to damages set forth in Section 11.4(b) of the Plan and Acquirer
and/or the Indemnified Persons may hold the Stockholders liable (severally but
not jointly) to the full extent of any such damages.

     2.2  Escrow Ledger.
          ------------- 

          (a) Required Information.  The Escrow Agent shall create and maintain
              --------------------                                             
a written record, in substantially the form attached as Exhibit B (the 'ESCROW
                                                        ---------             
LEDGER') of: (1) each Stockholder's name and address; (2) each Stockholder's
interest in the Escrow Shares by number of shares; (3) each Stockholder's
interest in other assets held in escrow; (4) each Stockholder's percentage
interest in the total Escrow Shares; (5) each Stockholder's interest in Escrow
Shares subject to pending Contested Claims (defined in Section 4.3); and (6)
Escrow Shares to be released to each Stockholder on the Release Date.  The
Escrow Ledger shall also reflect the total number of Escrow Shares remaining in
escrow.

          (b) Adjustments to the Ledger.  The Escrow Agent shall adjust the
              -------------------------                                    
Escrow Ledger to reflect changes in each Stockholder's interests in the Escrow
Shares.  This duty will continue until the Escrow Agent is required to deliver
each Stockholder's Escrow Shares pursuant to Section 2.3.  Absent manifest
error, all of the Escrow Agent's determinations as to the Escrow Ledger shall be
binding and conclusive on all parties to this Agreement.  Adjustments to the
Ledger shall include, but are not limited to, the following:

              (i) Adjustments for Capital Changes.  The Escrow Agent shall 
                  -------------------------------
adjust the Escrow Ledger to reflect the issuance of Additional Escrow Shares
pursuant to Section 2.1(b).

                                       4

 
               (ii)  Adjustments for Claims. The Escrow Agent shall deduct
                     ----------------------
Escrow Shares that become subject to pending Contested Claims of Acquirer or
other Indemnified Persons from column 6 of each Stockholder's account and add
such Escrow Shares to column 5 of each Stockholder's account. The Escrow Agent
shall deduct Escrow Shares that are charged and allocated to each Stockholder's
account pursuant to Article 4 in satisfaction of Claims by Acquirer or other
Indemnified Persons from columns 2-6, as appropriate.

       2.3  Release of Escrow Shares to Stockholders.
            ---------------------------------------- 

            (a) Release of Escrow Shares Generally.  On the Release Date, in
                ----------------------------------                          
accordance with Section 2.3(c), the Escrow Agent shall certify the Escrow Share
balances reflected in the Escrow Ledger as of that date and release the
appropriate number of Escrow Shares to each Stockholder as designated in column
6 of the Escrow Ledger, which shall equal such Stockholder's original Escrow
Shares and Additional Escrow Shares, minus: (i) any Escrow Shares attributable
to such Stockholder that were returned to Acquirer in accordance with Article 4
in satisfaction of a Claim(s) by Acquirer or another Indemnified Person(s), and
(ii) any Escrow Shares attributable to such Stockholder that are subject to
pending Claims of Acquirer or other Indemnified Persons, to be held pursuant to
Section 2.3(b).

            (b) Escrow Shares Subject to Pending Claims.
                --------------------------------------- 
 
                (i)   Upon the Release Date and thereafter, the Escrow Agent
shall continue to hold any Escrow Shares that are subject to pending Claims
until the thirty day period in Section 4.2 expires. At that time, the Escrow
Agent shall, as appropriate, either return the Escrow Shares subject to such
claim pursuant to Section 4.2, or continue to hold the Escrow Shares subject to
such Claim pursuant to Section 2.3(b)(ii).

                (ii)  Upon the Release Date and thereafter, the Escrow Agent
shall continue to hold any Escrow Shares that are subject to Contested Claims of
Acquirer or other Indemnified Persons, as designated in column 5 of the Escrow
Ledger, until the Escrow Agent receives written notice of resolution of each
specific Claim pursuant to Section 4.3(h). After the Escrow Agent receives such
notice, in accordance with Section 2.3(c), the Escrow Agent shall: (a) either
deliver or instruct the Exchange Agent to deliver to each Stockholder the number
of Escrow Shares, if any, due to each Stockholder in accordance with the
resolution of the Claim; (b) if applicable, charge and allocate Escrow Shares to
each Stockholder in satisfaction of the resolution of the Claim and either
return or instruct the Exchange Agent to return such Escrow Shares back to
Acquirer; and (c) notify the Representative in writing of any deduction of
Escrow Shares as promptly as reasonably practicable. The Escrow Agent shall make
the appropriate entries in the Escrow Ledger.

            (c) Procedure for Release and Delivery.  Within seven (7) business
                ----------------------------------                            
days after the Release Date (or with respect to Escrow Shares held pursuant to
Section 2.3(b), within seven (7) business days after the Escrow Agent's receipt
of written notice of a resolution of a Claim pursuant to Section 4.3(h)), the
Escrow Agent shall deliver, or instruct the Exchange 

                                       5

 
Agent to deliver, the Escrow Shares to each Stockholder by mailing (by
registered or certified mail, return receipt requested) by express courier to
the address set forth opposite each Stockholder's name on the Escrow Ledger (or
such other address as provided in writing by the Representative to the Escrow
Agent). No fractional Escrow Shares will be delivered; instead, Acquirer will
pay cash in lieu of any fractions of Escrow Shares in an amount equal to the
product of such fraction multiplied by the value of an Escrow Share as
determined in accordance with Section 4.5. The Escrow Agent and Acquirer will
cooperate to determine the amounts of such cash payments in lieu of fractional
shares to be made, and Acquirer will notify the Escrow Agent after such payments
have been made.

     3.   CLAIMS

          3.1  'Claim' Defined.  As used herein, the term 'CLAIM' means a claim
               ---------------

other Indemnified Person.  Acquirer agrees that it will make Claims only as
permitted by Article 11 of the Plan.

               --------------- 
 
               (a) When a Notice of Claim is Required.  An officer of Acquirer
                   ----------------------------------
shall execute and deliver written notice of a Claim (a 'NOTICE OF CLAIM') to the
Representative and the Escrow Agent as promptly as reasonably practicable, and
in no event after the Release Date, upon:
 
                   (i)   Acquirer's discovery of any inaccuracy,
misrepresentation or breach of or default in connection with any of the
provisions of Section 11.2 of the Plan; or

Order or Proceeding brought by any third Person against Acquirer and/or any
Indemnified Person that is based upon or includes assertions that would, if
true, constitute an inaccuracy, misrepresentation, breach of or default in
connection with any of the provisions of Section 11.2 of the Plan, (a 'THIRD
PARTY PROCEEDING');

               (b) Failure to Provide Notice of Claim.  Failure to provide such
                   ----------------------------------                          
notice in a timely manner shall not reduce Acquirer's indemnification rights or
the indemnification obligations of the Stockholders in this Agreement and under
the Plan, unless the failure to provide such notice materially impairs the
indemnifying party's ability to defend the Claim, and then only to the extent of
such impairment.

          3.3  Contents of Each Notice of Claim.  Each Notice of Claim given by
               --------------------------------                                
Acquirer pursuant to Section 3.2 shall be set forth in writing and shall contain
the following information to the extent it is reasonably available to Acquirer:
 
               (a) Statement of Damages.  The statement of damages shall 
                   --------------------    
include: (i) the amount of Target Damages that Acquirer believes has actually
been incurred by Acquirer 

                                       6

 
and/or any other Indemnified Person in connection with the Claim, reduced by any
recovery under policies of insurance, and (ii) Acquirer's good faith estimate of
the reasonably foreseeable maximum amount of the alleged Target Damages that
will ultimately be incurred by Acquirer and/or any other Indemnified Person in
connection with such Claim, including without limitation any Target Damages from
a potential Third Party Proceeding.

               (b) Statement of Basis for Damages.  The statement of basis for
                   ------------------------------                             
damages shall include: (i) a brief description, in reasonable detail, of the
facts, circumstances or events giving rise to the alleged Target Damages based
on Acquirer's or any other affected Indemnified Person's good faith belief, and
(ii) if applicable, specific references to the provisions of the Plan alleged to
have been breached.

          3.4  Requirement of Resolution of Claims.  The Escrow Agent shall not
               -----------------------------------                             
act regarding any of the Escrow Shares held pursuant to a Notice of Claim until
such Notice of Claim has been resolved in accordance with Article 4 and, in the
case of a Contested Claim, it receives appropriate notice pursuant to Section
4.3(h).
  
     4.   RESOLUTION OF CLAIMS
 
     Any Notice of Claim received by the Representative and the Escrow Agent
pursuant to Article 3 shall be resolved as follows:

          4.1  Third Party Proceedings.  Acquirer shall have the right, at the
               -----------------------                                        
Stockholders' expense, to select counsel in connection with conducting the
defense or handling each Third Party Proceeding and defend or handle such Third
Party Proceeding in such manner as Acquirer may deem reasonably appropriate
(including without limitation settlement or compromise of such Third Party
Proceeding); provided, however, that Acquirer: (a) shall keep the Representative
timely apprised of the status of such Third Party Proceeding, and (b) shall not
settle or compromise such Third Party Proceeding without the prior written
consent of the Representative (which consent shall not be unreasonably
withheld).  The reasonable costs and expenses incurred by Acquirer in connection
with such defense (including but not limited to reasonable attorneys' fees,
other professionals' and experts' fees and court or arbitration costs) shall be
included in the Target Damages for which Acquirer may seek indemnity pursuant to
a Claim made by Acquirer or an Indemnified Person hereunder.  If Acquirer
defends or handles the Third Party Proceeding, the Representative and the
Stockholders shall cooperate with Acquirer and shall be entitled to participate
in the defense or handling of the Third Party Proceeding with their own counsel
and at their own expense.
 
          4.2  Uncontested Claims.  If, within thirty calendar days after the
               ------------------                                            
Representative receives a Notice of Claim, the Representative does not contest
such Notice of Claim (an 'UNCONTESTED CLAIM') in a written notice delivered to
the Escrow Agent pursuant to Section 4.3, then the Escrow Agent shall: (a)
immediately charge and allocate against each Stockholder's accounts in the
Escrow Ledger the number of Escrow Shares required, pursuant to Section 4.5, to
satisfy the amount of Target Damages specified in such Notice of Claim (reduced

                                       7

 
by any recovery to date under policies of insurance not reflected in the Notice
of Claim); (b) update the Escrow Ledger to reflect the effect of the deduction
pursuant to Section 2.2(b)(ii); and (c) notify the Representative in writing of
the deduction of Escrow Shares as promptly as reasonably practicable.  The
number of Escrow Shares deducted hereunder shall be charged to and allocated
among the Stockholders pro rata according to each Stockholder's percentage
share, as set forth in column 4 of the Escrow Ledger.
 
          4.3  Contested Claims.  If Acquirer and the Escrow Agent receive a
               ----------------                                             
written notice contesting all, or a portion of, a Notice of Claim within the
thirty day period described in Section 4.2 (a 'CONTESTED CLAIM'), then the
parties will work together in good faith to resolve their dispute for up to
thirty (30) days.  If the Contested Claim is still not resolved, then: (a) such
Contested Claim shall be resolved by binding arbitration in accordance with the
provisions of this Section 4.3, and (b) the Escrow Agent shall continue to hold
the number of Escrow Shares sufficient, pursuant to Section 4.5, to satisfy the
maximum potential award to all Indemnified Persons under such Claim.  Any
portion of the Notice of Claim that is not contested by the Representative in
accordance with the foregoing provisions of this Section 4.3 shall be resolved
as an Uncontested Claim in accordance with Section 4.2.  Resolution of contested
claims shall be subject to the following rules:
 
               (a) Arbitration.  The parties agree that any Contested Claim 
                   -----------
shall be submitted to mandatory, final and binding arbitration before
J.A.M.S./ENDISPUTE or its successor ('J.A.M.S.'), pursuant to the United States
Arbitration Act, 9 U.S.C. (S) 1 et seq. and that any such arbitration shall be
conducted in San Mateo County, California. Either Acquirer or the Representative
may commence the arbitration process called for by this Agreement by filing a
written demand for arbitration with J.A.M.S. and giving a copy of such demand to
each of the other parties to this Agreement. The arbitration shall be conducted
in accordance with the provisions of J.A.M.S's streamlined arbitration rules and
procedures in effect at the time of filing of the demand for arbitration,
subject to the provisions of this Section 4.3. The parties will cooperate with
J.A.M.S. and with each other in promptly selecting an arbitrator from J.A.M.S.'s
panel of arbitrators in accordance with J.A.M.S.'s procedures for selecting
arbitrators, and in scheduling the arbitration proceedings in order to fulfill
the provisions, purposes and intent of this Agreement. The parties covenant that
they will participate in the arbitration in good faith, and that they will share
in its costs in accordance with Section 4.3(b).
 
               (b) Payment of Costs.  Each party will bear its own fees and
                   ----------------
expenses in connection with the arbitration, except that Acquirer and the
Stockholders shall each bear 50% of the expense of deposits and advances
required by the arbitrator; provided, however, that in the event that the
arbitrator finds that one party has substantially prevailed in the arbitration,
the prevailing party shall be entitled to an award of attorney's fees and costs,
arbitrator's fees and costs and all other costs of arbitration from the losing
party.

               (c) Award.
                   ----- 
 
                   (i) Upon the conclusion of any arbitration proceedings
hereunder, the arbitrator shall render findings of fact and conclusions of law
and a final written 

                                       8

 
arbitration award setting forth the basis and reasons for any decision reached
(the 'FINAL AWARD') and shall deliver such documents to the Escrow Agent, the
Representative and Acquirer. The Final Award shall constitute a conclusive
determination of all issues in question, binding upon the Representative, the
Stockholders and Acquirer, and shall not be contested by the Representative, the
Stockholders or Acquirer. Awards for Target Damages shall be subject to the
provisions of Section 11.4 of the Plan.

           (ii)   To the extent that the Final Award determines that Acquirer or
any other Indemnified Person has actually incurred Target Damages in connection
with the Contested Claim through the date of the Final Award ('INCURRED
DAMAGES'), the Final Award will set forth and award to Acquirer the amount of
such damages, reduced by any recovery under policies of insurance to date that
were not specified in the Notice of Claim.  In addition, the Final Award will
set forth an additional amount of Target Damages equal to the reasonably
foreseeable amount of alleged Target Damages that the arbitrator determines
(based on the evidence submitted by the parties in the arbitration) are
reasonably likely to be incurred by Acquirer and any other Indemnified Person as
a result of the facts giving rise to the Contested Claim ('ESTIMATED DAMAGES'),
which amount of Estimated Damages may, without limitation, include the amount of
damages claimed by a third party in an action brought against any Indemnified
Person based on alleged facts which, if true, would give rise to Target Damages.
The Escrow Agent will continue to hold Escrow Shares representing the Estimated
Damages, in accordance with Section 4.5, in escrow, including, if appropriate,
beyond the expiration of the Escrow Period, until and to the extent that: (A)
the arbitrator deems that Acquirer has actually incurred such Estimated Damages,
reduced by any recovery under policies of insurance to date that were not
specified in the Notice of Claim; (B) the arbitrator deems that Acquirer will
not actually incur any additional Estimated Damages; or (C) the parties come to
a written settlement agreement pursuant to Section 4.4.  Both Incurred Damages
and Estimated Damages owed to Indemnified Persons are deemed to be Target
Damages for purposes of this Agreement.
 
           (iii)  Upon issuance and delivery of the Final Award pursuant to
Section 4.3(c)(ii), and subject to receipt by the Escrow Agent of a written
notice of resolution of the Claim pursuant to Section 4.3(h), Acquirer will
immediately be entitled to recover: (A) the amount of any Incurred Damages
awarded to Acquirer under such Final Award, and (B) the amount of Estimated
Damages awarded under such Final Award to the extent that such Estimated Damages
do not arise from a Third Party Claim.  If the Final Award awards any Estimated
Damages to Acquirer that arise from a Third Party Claim then: (A) if the actual
amount of such Estimated Damages is determined by a settlement agreement or a
final judgment or arbitration award prior to the Resolution Date (defined
herein) for the Contested Claim with respect to which such Estimated Damages
were awarded under the Final Award, then for purposes of this Agreement, the
amount of such Estimated Damages owed to Acquirer will be the amount so
determined by such settlement agreement, judgment or award without regard to the
amount of Estimated Damages set forth in the Final Award, and (B) if the actual
amount of such Estimated Damages is not so determined prior to the Resolution
Date, then for purposes of this Agreement, the amount of such Estimated Damages
owed to Acquirer will be the amount of Target Damages awarded in the Final
Award.  For the purposes of this Agreement, the term 'RESOLUTION DATE' for a
Contested Claim shall mean the later of: (A) the Release Date, or (B) 

                                       9


the date on which the last timely filed Notice of Claim is resolved through
Final Award, as a settled claim or otherwise.
 
          (d)  Timing.  The Representative, Acquirer and the arbitrator shall
               ------                                                        
conclude each arbitration pursuant to this Section 4.3 as promptly as
practicable.  Time is of the essence with regards to all aspects of this
Agreement.
 
          (e)  Terms of Arbitration.  The arbitrator chosen in accordance with
               --------------------                                           
these provisions shall not have the power to alter, amend or otherwise affect
the terms of these arbitration provisions, the other provisions of this
Agreement or the Plan.
 
          (f)  Non-Exclusivity.  Although the use of arbitration in resolving
               ---------------                                               
Contested Claims under this Agreement is mandatory, this does not limit any
other rights or remedies which Acquirer may have, whether at law, in equity, by
contract or otherwise, all of which shall be cumulative (and not alternative).
Nothing in this Agreement shall limit any of the rights or remedies of Acquirer
under the Plan or any other Merger Agreement, and nothing in the Plan or any
other Merger Agreement shall limit any of the rights or remedies of Acquirer
under this Agreement.
 
          (g)  Multiplicity of Claims Permitted.  The assertion of any single
               --------------------------------                              
Claim for indemnification hereunder shall not bar Acquirer or an Indemnified
Person from asserting any other Claims hereunder.
 
          (h)  Notice of Resolution of Claim. The Escrow Agent shall not deliver
               ----------------------------- 
Escrow Shares held pursuant to a Contested Claim until the Escrow Agent receives
appropriate notice. Such notice must consist of: (i) written notice of the
resolution of such Claim executed by both the Representative and Acquirer; (ii)
a written settlement agreement pursuant to Section 4.4; (iii) delivery to the
Escrow Agent of an appropriate final non-appealable order by a court of
competent jurisdiction; or (iv) delivery to the Escrow Agent of a copy of the
Final Award of an arbitrator or court. The Escrow Agent shall act on such notice
without further inquiry in accordance with Sections 2.3(b) and (c).
 
     4.4  Settled Claims.  If a Claim (including a Contested Claim) is
          --------------                                              
settled by a written settlement agreement executed by the Representative and
Acquirer, then the Representative and Acquirer shall promptly deliver such
written settlement agreement to the Escrow Agent with written instructions on
the appropriate charges or adjustments to be made to the Escrow Ledger, and the
Escrow Agent shall promptly release and/or return the Escrow Shares subject to
such claim in accordance with Sections 2.3(b) and 2.3(c).
 
     4.5   Determination of Number of Escrow Shares for Claims.  Unless a
           ---------------------------------------------------         
specific number of Escrow Shares is specified, any amount owed to Acquirer under
this Agreement will be immediately payable to Acquirer, subject to Section
4.3(h), by deducting pro rata each Stockholder's account in the Escrow Ledger
the number of Escrow Shares equal to: (a) the Target Damages for that Claim,
divided by, (b) the Closing Price (as defined in the Plan as of the Closing

                                       10

 
Date). Within ten (10) business days after the Closing Date, Acquirer will
notify the Escrow Agent of the Closing Price.
 
          4.6  No Election of Remedies.  Acquirer may institute Claims against
               -----------------------                                        
the Escrow Shares and in satisfaction thereof may elect to have such Escrow
Shares deducted from the Escrow Ledger, after any notice to the Representative
required hereunder, without making any other claims directly against the
Stockholders and without rescinding or attempting to rescind the transactions
consummated pursuant to the Plan.  The assertion of any single Claim for
indemnification hereunder will not bar Acquirer from asserting other Claims
hereunder.  Acquirer need not exhaust any other remedies that may be available
to it but may proceed directly in accordance with the provisions of this
Agreement.
 
 
     5.   THE ESCROW AGENT
 
          5.1  Limitation of Escrow Agent's Liability/Responsibility. The Escrow
               ----------------------------------------------------- 
Agent shall incur no liability with respect to any action taken or suffered by
it in reliance upon any notice, direction, instruction, consent, statement or
other document believed by it to be genuine and duly authorized, nor for any
other action or inaction, except its own willful misconduct, fraud or gross
negligence. The Escrow Agent shall have no duty or responsibility: (a) for the
validity or sufficiency of this Agreement, nor to inquire into or investigate
the validity, accuracy or content of any document that it receives, (b) to
verify that the Representative or Acquirer received a Notice of Claim or other
required notice, and (c) other than those expressly set forth in this Agreement
and the implied duty of good faith and fair dealing. The Escrow Agent will not
be required to take any action hereunder involving any expense unless the
payment of such expense is made or provided for in a manner satisfactory to it.
Nothing in this Agreement shall be deemed to impose upon the Escrow Agent any
duty to qualify to do business or to act as a fiduciary or otherwise in any
jurisdiction other than the State of California.

          5.2  Use of Agents and Reliance on Counsel.  The Escrow Agent may
               -------------------------------------                       
execute any of its powers or responsibilities hereunder and exercise any rights
hereunder either directly or through its agents or attorneys and shall be
entitled to consult with its legal counsel, including in-house legal counsel, as
to any questions or matters arising hereunder.  The reasonable, good faith
written opinion of such legal counsel shall be full and complete authorization
and protection to the Escrow Agent in respect of any act or omission by the
Escrow Agent undertaken in good faith and in accordance with the opinion of such
legal counsel.  The Escrow Agent shall have no liability for the conduct of any
outside attorneys, accountants or other similar professionals it retains.
 
          5.3  Indemnification of the Escrow Agent.
               ----------------------------------- 
 
               (a)  For the purposes of this Section 5.3, references to the
Escrow Agent shall include the Escrow Agent's officers, directors, employees,
counsel and agents.
 

                                       11

 
               (b)  Each party to this Agreement other than the Escrow Agent
(each an 'INDEMNIFYING PARTY' and together the 'INDEMNIFYING PARTIES') will
severally reimburse, indemnify and hold harmless the Escrow Agent from and
against any damage, liability or loss suffered, incurred by, or asserted against
the Escrow Agent (including amounts paid in settlement of any action, suit,
proceeding, or claim brought or threatened to be brought and including
reasonable expenses of legal counsel, collectively, 'LOSS') arising out of, in
connection with or based upon any act or omission by the Escrow Agent relating
in any way to this Agreement or the Escrow Agent's services hereunder. This
indemnity will exclude any indemnification for any Loss arising in whole or in
part, directly or indirectly, from any gross negligence or willful misconduct on
the Escrow Agent's part. Anything in this Agreement to the contrary
notwithstanding, in no event will the Escrow Agent be liable for special,
indirect or consequential loss or damage of any kind whatsoever (including but
not limited to lost profits) suffered by another party to this Agreement or by
any Stockholder, even if the Escrow Agent has been advised of the likelihood of
such loss or damage and regardless of the form of action.

               (c)  Each Indemnifying Party may participate at its own expense
in the defense of any claim or action that may be asserted against the Escrow
Agent related to this Agreement, and if the Indemnifying Parties so elect, the
Indemnifying Parties may assume the defense of such claim or action; provided,
however, that, if there exists a conflict of interest that would make it
inappropriate, in the sole discretion of the Escrow Agent, for the same counsel
to represent both Escrow Agent and the Indemnifying Parties, the Escrow Agent's
retention of separate counsel will be reimbursable as herein above provided.
The Escrow Agent's right to indemnification hereunder will survive the Escrow
Agent's resignation or removal as the Escrow Agent and will survive the
termination of this Agreement by lapse of time or otherwise.

               (d)  The Escrow Agent will notify each Indemnifying Party by
letter, or by telephone or telecopy confirmed by letter, of any receipt by
Escrow Agent of a written assertion of a claim against the Escrow Agent arising
out of this Agreement, or any action commenced against the Escrow Agent arising
out of this Agreement, within five (5) business days after the Escrow Agent's
receipt of written notice of such claim. However, the Escrow Agent's failure to
so notify each Indemnifying Party will not operate in any manner whatsoever to
relieve an Indemnifying Party from any liability that it may have to the Escrow
Agent under this Section 5.3 or otherwise unless such failure by the Escrow
Agent to give such notice materially prejudices such Indemnifying Party.

          5.4  Compensation and Expenses of Escrow Agent.  All fees and expenses
               -----------------------------------------                        
of the Escrow Agent incurred in the ordinary course of performing its
responsibilities hereunder shall be paid by Acquirer upon receipt of a written
invoice by Escrow Agent.
 
          5.5  Resolution of Conflicting Demands.  In the event conflicting
               ---------------------------------                           
demands are made or conflicting notices are served upon the Escrow Agent with
respect to the Escrow Shares or the Escrow Ledger, the Escrow Agent shall have
the right, at the Escrow Agent's election, to either: (a) give written notice to
the other parties to this Agreement that it has received conflicting
instructions from Acquirer and the Representative and is refraining from taking
action until it receives instructions consented to in writing by both Acquirer
and the Representative, or 

                                       12

 
(b) resign so that a successor escrow agent can be appointed pursuant to Section
5.6. In the further event that the Escrow Agent gives written notice under '(a)'
above and does not receive instructions consented to in writing by both Acquirer
and the Representative within thirty (30) calendar days, then the Escrow Agent
may file a suit in interpleader and obtain an order from a court of competent
jurisdiction located in San Mateo County, California, requiring the parties to
interplead and litigate in such court their several claims and rights among
themselves. In this case, the Escrow Agent shall thereby be fully released and
discharged from all further obligations imposed upon it under this Agreement
with respect to the matters that are the subject of such interpleader suit, and
Acquirer shall pay the Escrow Agent all costs, expenses and reasonable
attorneys' fees expended or incurred by the Escrow Agent pursuant to the
exercise of Escrow Agent's rights under this paragraph.
 
          5.6  Successor Escrow Agent.
               ---------------------- 
 
               (a)  In the event the Escrow Agent becomes unavailable or
unwilling to continue in its capacity as Escrow Agent hereunder, the Escrow
Agent may resign and be discharged from its duties hereunder by giving notice of
resignation to the parties to this Agreement, specifying a date not less than
ten (10) days following such notice date of when such resignation shall take
effect and refunding to Acquirer any prepaid but unearned fees previously paid
by Acquirer to the Escrow Agent hereunder. Acquirer shall designate a successor
Escrow Agent reasonably satisfactory to the Representative prior to the
expiration of such ten day period by giving written notice to the Escrow Agent
and the Representative. If no successor escrow agent is named by Acquirer, then
the Escrow Agent may apply to a court of competent jurisdiction for the
appointment of a successor Escrow Agent. In either case, the Escrow Agent shall
promptly transfer the Escrow Shares and Escrow Ledger to the designated
successor Escrow Agent.
 
               (b)  In the event Escrow Agent is merged with, acquired or
otherwise combined with another entity, or Escrow Agent transfers all or
substantially all of its corporate trust business (including the escrow
contemplated by this Agreement) to another institution, the successor as a
result of such transaction will be the Escrow Agent hereunder without any
further action by the parties hereto.
 
 
     6.   THE STOCKHOLDERS' REPRESENTATIVE
 
          6.1  Powers of the Representative.    In order to receive their
               ----------------------------                              
consideration pursuant to the Plan, each Stockholder has consented to: (a) the
appointment of the Representative (and any replacement hereunder) as
representative of the Stockholders and as the agent and attorney-in-fact for and
on behalf of each Stockholder, and (b) so long as all Stockholders are treated
in material respects in the same manner, the taking by the Representative of any
and all actions and the making of any decisions required or permitted to be

of Claims; (ii) agree to, negotiate, enter into 

                                       13

courts and awards of arbitrators, with respect to Claims; (iii) take all actions
necessary in connection with the waiver of any condition to the obligations of
the Stockholders under this Agreement; (iv) waive any right of any or all of the
Stockholders; (v) give and receive all notices required to be given under this
Agreement; (vi) resolve any Claims; and (vii) take all actions necessary in the
sole judgment of the Representative for the accomplishment of the foregoing and
all of the other terms, conditions and limitations of this Agreement. The
Stockholders shall be bound by all actions taken and decisions made by the
Representative in connection with this Agreement. Acquirer and the Escrow Agent
shall be entitled to rely on any action or decision of the Representative.

          6.2  Limitation of the Representative's Liability.  In performing the
               --------------------------------------------                    
functions specified in this Agreement, the Representative shall not be liable to
the Stockholders in the absence of fraud, gross negligence or willful misconduct
(including willful breach of this Agreement) on the part of the Representative.
 
          6.3  Indemnification.  Each of the Stockholders agree to indemnify and
               ---------------                                                  
hold the Representative harmless from and against any and all loss, liability,
damages, cost or expense (including but not limited to reasonable attorneys' and
experts' fees and court costs) incurred by the Representative in connection with
the performance of the Representative's duties and obligations under this
Agreement (other than any loss, liability, damages, cost or expense incurred
through acts or omissions constituting fraud, gross negligence or willful
misconduct on the Representative 's part).
 
          6.4  No Compensation; Reimbursement for Expenses.  Except as stated in
               -------------------------------------------                      
Section 6.3 and in this paragraph, the Representative shall not be entitled to
receive any compensation for his or her services in connection with this
Agreement.  Any out-of-pocket costs and expenses reasonably incurred by the
Representative in connection with actions taken pursuant to the terms of this
Agreement shall be paid by the Stockholders in proportion to their percentage
share set forth in column 4 of the Escrow Ledger promptly upon the
Representative's written request to the Stockholders and, at the
Representative's option, may be taken by the Representative from the Escrow
Shares reflected in the Escrow Ledger after the final resolution of all Claims
made under this Agreement.
 
          6.5  Successor Representative.  In the event that Representative dies,
               ------------------------

representative of the Stockholders hereunder, a substitute representative of the
Stockholders shall be appointed by the Stockholders with beneficial interests in
a majority of the total Escrow Shares, as reflected in column 4 of the Escrow
Ledger, to act as representative of the Stockholders hereunder.
 
 
     7.   GENERAL PROVISIONS
 
          7.1  Entire Agreement.  Except as otherwise provided in the Plan, this

Agreement constitutes the entire understanding and agreement of the parties with
respect to the 

                                       14

 
subject matter of this Agreement and supersedes all prior agreements or
understandings, written or oral, between the parties with respect to the subject
matter hereof. As between the Escrow Agent and the other parties hereto, all
such parties agree that the Escrow Agent's duties are defined only in this
Agreement, any contrary provisions of the Plan notwithstanding.

of its rights and obligations hereunder without the prior written consent of the
Escrow Agent and the Representative, which consent shall not be unreasonably
withheld.  Except for assignments in connection with permitted transfers of
Escrow Shares under Section 2.1(d) of this Agreement, Target may not assign any
of its rights or obligations hereunder, nor may rights or obligations be
assigned by operation of law, without the prior written consent of Acquirer.

the respective parties hereto and their attorneys and have been reviewed by each
party hereto.  Accordingly, no ambiguity in the language of this Agreement will
be construed for or against either party.

               ----------------                                               
will mean a section in, article in or exhibit to this Agreement unless otherwise
explicitly set forth.  The titles and headings herein are for reference purposes
only and will not in any manner limit the construction of this Agreement, which
will be considered as a whole.
 
          7.5  Amendment.  This Agreement may be amended by the written
               ---------                                               
agreement of Acquirer, the Escrow Agent and the Representative; provided,
however, that, if the Escrow Agent does not agree to an amendment agreed upon by
Acquirer and the Representative, then the Escrow Agent shall resign and Acquirer
shall appoint a successor Escrow Agent in accordance with the provisions of
Section 5.6.  No amendment of the Plan shall increase or alter the Escrow
Agent's duties, responsibilities or liability hereunder without the Escrow
Agent's written agreement.

               ------                                                           
breach of any provision of this Agreement shall be effective unless it is set
forth in a writing signed by such party.  No waiver by any party of any such
condition or breach, in any one instance, shall be deemed to be a further or
continuing waiver of any such condition or breach or a waiver of any other
condition or breach of any other provision contained herein.  The failure of any
party to enforce any of the provisions hereof will not be construed to be a
waiver of the right of such party thereafter to enforce such provisions.
 
          7.7  Severability.  If any provision of this Agreement or its
               ------------                                            
application will for any reason and to any extent be invalid or unenforceable,
the remainder of this Agreement and application of such provision to other
persons or circumstances will be interpreted so as to effect the intent of the
parties hereto.  The parties will replace such void or unenforceable provision
of 

                                       15

 
this Agreement with a valid and enforceable provision that will achieve, to the

unenforceable provision.

               --------------                                                   
remedies herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby or by law on such party,
and the exercise of any one remedy will not preclude the exercise of any other.
 
          7.10 Jurisdiction.  The parties submit to the jurisdiction of the
               ------------                                                
Superior Court of the State of California and the United Stated District Court
for the Northern District of California for the purposes of: (a) confirming any

               --------------------
