                                                                      ----------
Notice").  Buyer shall be deemed to have accepted the Allocation Notice, and it
------                                                                         
shall be deemed final, unless Buyer provides written notice of disagreement to
ICS within  thirty (30) days of receipt of the Allocation Notice (the
"Disagreement Notice").  If Buyer provides a Disagreement Notice, the parties
--------------------                                                         
shall negotiate in good faith to resolve the differences.  If the disagreements
cannot be resolved within thirty (30) days of Sellers receipt of the
Disagreement Notice, ICS shall engage a national independent accounting firm
(the "Accountant"), acceptable to the Buyer, to resolve the differences.  The
      ---------                                                              
Accountant will be requested to resolve the dispute and determine the correct
allocation in accord with Section 1060 of the Code, and issue its report within
30 days  of engagement, in writing to ICS and Buyer (the "Accountant Report").
                                                          -----------------    
One-half of the fees of the Accountant shall be borne by the Buyer, and one-half
of such fees shall be borne by ICS. No party will take a position on any Tax
Return, before any governmental Tax agency or in a judicial proceeding that is
inconsistent with the Allocation Notice, if final, or the Accountant Report,
except as required by law.  To the extent required by Section 1060, the
Allocation Notice or Accountant Report, as appropriate, will be revised to
reflect any adjustment of the Purchase Price.

          (d) Transfer Taxes; Property Taxes.  The Sellers, on the one hand, and
              ------------------------------

party shall promptly pay and discharge when due the entire amount of any such
Transfer Taxes for which it is primarily liable in accordance with applicable
law.  Each party shall reimburse the other party (the "Requesting Party") for
                                                       ----------------      
its share of such Transfer Taxes paid by the Requesting Party within fifteen
(15) business days of receipt of reasonable evidence that the Requesting Party
has paid the Transfer Tax that is the subject of the request for reimbursement.
The parties shall cooperate with each other to the extent reasonably requested
and legally permitted to minimize any Transfer Taxes.  Any personal property
taxes payable in respect of the Acquired Assets shall be apportioned at the
Closing, based on current tax bills if available; and if not available, based on
the most recent tax bills available with appropriate subsequent adjustment when
bills for the current year are received.

          2.4 The Closing.  The closing of the transactions contemplated by this
             -----------

     (ii) as to property held subject to a Lease, upon obtaining any required
consents of the landlord, the Lease will continue to be legal, valid, binding
and enforceable against the Seller that is a party thereto and against the other
party thereto, and is in full force and effect on identical terms following the
consummation of the transactions contemplated hereby (including the assignments
and assumptions referred to in Article II above);

    (iii) as to property subject to a Lease, to Seller's Knowledge, no third
party to the Lease has repudiated any provisions thereof;

     (iv) neither Seller has assigned, transferred, conveyed, mortgaged, deeded
in trust or encumbered any interest in the property or the leasehold, except as
described in Schedule 3.12(a) hereto;
             ----------------       

     (v)  all facilities used by either Seller thereunder have received all
material approvals of governmental authorities (including licenses and permits)
required in connection with the operation thereof as conducted by either Seller
and have been operated and maintained in accordance with applicable laws, rules
and regulations in all material respects, except to the extent that any such
violation would neither have a Material Adverse Effect on the Acquired Assets
nor prevent the consummation of the transactions contemplated hereunder; and

    (vi)  all facilities used thereunder are supplied with utilities and other
services necessary for the operation of said facilities.

          (b)   Each Seller has good and valid title to, or, in the case of
leased properties and assets, valid leasehold interests in, all of its tangible
properties and assets, real, personal and mixed, in each case to the extent
included in the Acquired Assets, and, assuming the receipt of the Required
Consents and the consummation of the transactions contemplated hereby, the
Acquired Assets will be sold to Buyer at the Closing free and clear of any
Liens.

          (c)   All material items of equipment owned or leased by either
Seller used in the Business (the "Equipment") which are included in the Acquired
                                 -----------
Assets are in good operating condition, regularly and properly maintained,
subject to normal wear and tear.

          (d)   Except as set forth on Schedule 3.12(d), the Acquired Assets

conduct of the Business.

          3.13  Intellectual Property.
                --------------------- 

                (a)  Schedule 3.13(a) lists all of Sellers' Registered
                     ----------------
Intellectual Property owned by, or filed in the name of either Seller (the
"Seller Registered Intellectual Property"), and lists any proceedings or actions
before any court, tribunal (including the PTO or equivalent authority anywhere
in the world) related to any of the Seller Registered Intellectual Property.

                                     -16-
<PAGE>
 
         (b)  Each item of Seller Intellectual Property, including all Seller
Registered Intellectual Property listed in Schedule 3.13(a), is free and clear
                                           ----------------    
of any Liens. Sellers (i) are the exclusive owner of all trademarks, service
marks, trade dress and trade names used in connection with the conduct of the
Business, including the sale of any products or technology or the provision of
any services by Seller and (ii) own exclusively, and have good title to, all
works of authorship and all associated copyrights that are or are part of or
related to Sellers' products sold, licensed or otherwise provided in the
Business or other works of authorship that Sellers otherwise purport to own in
connection with the conduct of the Business.

          (c)  To the extent that any Intellectual Property has been developed
by any Person other than Sellers for use in the conduct of the Business for
which either Seller has, directly or indirectly, paid, such Seller has a written
agreement with such Person with respect thereto and such Seller thereby has
obtained ownership of, and is the exclusive owner of, all such developed
Intellectual Property by operation of law or by valid assignment. All employees
of each Seller have entered into a valid and binding written agreement with such
Seller sufficient to vest title in such Seller of all Intellectual Property
created by such employee in the scope of his or her employment with such Seller.

          (d)   Except as set forth in Schedule 3.13(d), neither Seller has
                                        ----------------                    
transferred ownership of or granted any license of or right to use or authorized
the retention of any rights to use any Intellectual Property that is or was
Seller Intellectual Property, to any other Person, other than transfers to the
other Seller, and (ii) implied non-exclusive licenses granted in connection with
the sale of inventory in the Ordinary Course of Business.

          (e)   The  Acquired Assets include all Intellectual Property used in
and/or necessary to the conduct of the Business as it currently is conducted or
is reasonably contemplated to be conducted, including the design, development,
manufacture, use, import and sale of the products, technology and services in
the Business (including products, technology or services currently under
development in the Business).

          (f)    Other than "shrink-wrap" and similar widely available
commercial end-user licenses, the contracts, licenses and agreements listed in
Schedule 3.13(f) include all contracts, licenses and agreements, to which Seller
----------------
is a party with respect to any Intellectual Property of any Person other than
either Seller related to the conduct of the Business. No Person other than
either Seller has ownership rights to improvements made by either Seller in
Intellectual Property which has been licensed to either Seller and exploited in
the conduct of the Business.

          (g)    Schedule 3.13(g) lists all contracts, licenses and agreements
                 ----------------                                             
between either Seller and any other Person wherein or whereby either Seller has
agreed to, or assumed, any obligation or duty to warrant, indemnify, reimburse,
hold harmless, guaranty or otherwise assume or incur any obligation or liability
or provide a right of rescission with respect to the infringement or
misappropriation by either Seller or such other Person of the Intellectual
Property of any Person other than either Seller, in any such case arising out of
the Business.

                                     -17-
<PAGE>
 
          (h)    The operation of the Business as is currently conducted or is
contemplated to be conducted, including the design, development, use, import,
manufacture and sale of the products related to the Acquired Assets, does not,
and will not, when conducted by Buyer in substantially the same manner following
the closing, infringe or misappropriate the Intellectual Property of any Person,
violate the rights of any Person (including rights to privacy or publicity), or
constitute unfair competition or trade practices under the laws of any
jurisdiction, and neither Seller has received notice from any Person claiming
that such operation or any act, product, technology or service (including
products, technology or services currently under development) of either Seller
infringes or misappropriates the Intellectual Property of any Person or
constitutes unfair competition or trade practices under the laws of any
jurisdiction (nor is either Seller aware of any Basis therefor).

         (i)     Each item of Seller Registered Intellectual Property is valid
and subsisting. All necessary registration, maintenance and renewal fees in
connection with such Seller Registered Intellectual Property have been paid and
all necessary documents and certificates in connection with such Seller
Registered Intellectual Property have been filed with the relevant patent,
copyright, trademark or other authorities in the United States or foreign
jurisdictions, as the case may be, for the purposes of maintaining such
Registered Intellectual Property. For each portion of the Acquired Assets that
constitutes or includes a copyrightable work, a Seller has registered the
copyright in the latest version of such work with the U.S. Copyright Office. In
each case in which a Seller has acquired any Intellectual Property rights from
any Person, such Seller has obtained a valid and enforceable assignment
sufficient to irrevocably transfer all rights in such Intellectual Property
(including the right to seek past and future damages with respect to such
Intellectual Property) to such Seller and, to the maximum extent provided for
by, and in accordance with, applicable laws and regulations, such Seller has
recorded each such assignment with the relevant governmental authorities,
including the PTO, the U.S. Copyright Office, or their respective equivalents in
any relevant foreign jurisdiction, as the case may be. The Sellers have not
claimed "Small Business Status", or other particular status in the application
for any Seller Registered Intellectual Property, which claim of status was, at
the time made, or which has since become, inaccurate or false or that will no
longer be true and accurate as a result of the Closing.

          (j)    There are no contracts, licenses or agreements between a Seller
and any other Person with respect to Seller Intellectual Property under which
there is any dispute, or, to Sellers' Knowledge, any threatened dispute
regarding the scope of such agreement or performance under such agreement,
including with respect to any payments to be made or received by either Seller
thereunder.

          (k)    To the Sellers' Knowledge, no Person is infringing or
misappropriating any Seller Intellectual Property.

          (l)    Each Seller has taken all commercially reasonable steps that
are required to protect Sellers' rights in confidential information and trade
secrets of either Seller relating to the Business or provided by any other
Person to either Seller relating to the Business. Without limiting the
foregoing, each Seller has, and enforces, a policy requiring each employee,
consultant and contractor working in the Business to execute adequate
proprietary information, confidentiality and assignment 

                                     -18-
<PAGE>
 
agreements, and all current and former employees, consultants and contractors of
each Seller have executed such an agreement.

          (m)    No Seller Intellectual Property or product, technology or
service of either Seller used, licensed, sold or otherwise provided in the
conduct of the Business is subject to any proceeding or outstanding decree,
order, judgment, agreement or stipulation that restricts in any manner the use,
transfer or licensing thereof by either Seller or may affect the validity, use
or enforceability of the Seller Intellectual Property.

          (n)    No (i) product, technology, service or publication of Seller
relating to the Business or (ii) material published or distributed by Seller
relating to the Business constitutes obscene material, a defamatory statement or
material, false advertising or otherwise violates any law or regulation.

          (o)    All of each Seller's products related to the Business will
record, store, process, calculate and present calendar dates falling on and
after (and if applicable, spans of time including) January 1, 2000, and will
calculate any information dependent on or relating to such dates in the same
manner, and with the same functionality, data integrity and performance, as the
products record, store, process, calculate and present calendar dates on or
before December 31, 1999, or calculate any information dependent on or relating
to such dates, because the products do not record, store, process, calculate or
present calendar dates whatsoever. All of each Seller's products related to the
Business (i) will lose no functionality with respect to the introduction of
records containing dates falling on or after January 1, 2000 and (ii) will be
interoperable with other products used by Buyer that may deliver records to
Seller's products or receive records from such products of either Seller, or
interact with such products, including back-up and archived data.

          (p)     All Acquired Assets were written and created solely by either
(i) employees of either Seller acting within the scope of their employment or
(ii) by third parties who have validly assigned all of their rights, including
Intellectual Property rights therein to either Seller, and no third party owns
or has any rights to any of the Acquired Assets or any Intellectual Property
rights therein.

          (q)     Except as set forth in Schedule 3.13(q), all Acquired Assets
                                         ---------------                      
and all portions thereof will be fully, transferable, alienable or licensable by
Buyer without restriction and without payment of any kind to any third party.

          (r)    The contracts, licenses and agreements listed on Schedule
                                                                  --------
3.13(f) include all material contracts, licenses and agreements pursuant to
-------
which any Person, including any Affiliate of either Seller, has licensed any
Intellectual Property to either Seller for use in the Business. Neither Seller
is in breach of or has failed to perform under, any of the foregoing contracts,
licenses or agreements and, to the Sellers' Knowledge, no other party to any
such contract, license and agreement is in breach thereof or has failed to
perform thereunder.

          (s)    Neither this Agreement nor the transactions hereby
contemplated, including without limitation the assignment to Buyer of any
contract, license or agreement to which either Seller

                                     -19-
<PAGE>
 
is a party, will result in the Buyer's granting to any third party any right to
or with respect to any Intellectual Property owned by or licensed to Buyer, or
will result in the Buyer's being bound by or subject to any non-compete or other
restriction on the operation or scope of Buyer's business.

       3.14  Contracts.  Schedule 3.14 attached hereto lists the following
             ---------   -------------

terms and conditions of each oral agreement referred to on Schedule 3.14 (each a
                                                           -------------        
"Contract").  Each Seller is in compliance with and has not breached, violated
 --------                                                                     
or defaulted under, or received notice that it has breached, violated or
defaulted under, any of the terms or conditions of any Contract to which such
Seller is a party or by which it is bound and which is included in the Acquired
Assets, nor, to Sellers' Knowledge is there any event that has occurred that
would constitute such a breach, violation or default with the lapse of time,
giving of notice or both.  Each Contract is in full force and effect and, except
as otherwise disclosed in Schedule 3.14, to the Sellers' Knowledge, is not
                          -------------                                   
subject to any default thereunder by any party obligated to either Seller
pursuant thereto.  No provision in any of the contracts would prevent the Buyer,
following the Closing Date, from exercising all of the Sellers' rights under the
Contracts included in the Acquired Assets without the payment of any additional
amounts or consideration other than ongoing fees, royalties or payments which
the Seller that is a party thereto would otherwise be required to pay had the

material consent, license, permit, grant or other authorization issued to either
Seller by a Governmental Entity pursuant to which either Seller currently

                                      ---------------------            
Authorizations are in full force and effect and constitute all Seller
Authorizations required to permit the Sellers to operate or conduct the Business
or hold any interest in its properties or assets used in the Business, except to
the extent that the failure to obtain any required consent, license, permit,
grant or authorization would not 

                                     -21-

have a Material Adverse Effect on the Acquired Assets or would not prevent the
consummation of the transactions contemplated hereby.

        3.16 Litigation.  There is no action, suit or proceeding of any nature
             ----------

Basis therefor), against either Seller, its properties or any of its officers or
directors which, if not resolved in favor of the Sellers, its properties or any
of its officers or directors, as the case may be, would have a Material Adverse
Effect on the Acquired Assets or would prevent the consummation of the
transactions contemplated hereby. There is no investigation pending or, to
Sellers' Knowledge threatened, against either Seller, its properties or any of
its officers or directors (nor, to Sellers' Knowledge, is there any Basis
therefor) relating to or affecting the Business by or before any Governmental
Entity which, if not resolved in favor of the Sellers, its properties or any of
its officers or directors, as the case may be, would have a Material Adverse
Effect on the Acquired Assets or would prevent the consummation of the
transactions contemplated hereby. No Governmental Entity has at any time
challenged or questioned the legal right of the Sellers to conduct the Business
as presently or previously conducted.

             (a)  Hazardous Material.  Neither Seller has:  (i) operated any

to own or exercise control of such assets, properties and stock.

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

or satisfied by it hereunder; provided, however, that the delivery of any notice

Clearance").
---------   

     6.12 Covenant Not to Solicit.
          ----------------------- 

          (a)  For a period commencing on the Closing Date and ending on the
third anniversary of the Closing Date, neither ICS nor Seller (and their
successors and assigns) shall (nor shall either Seller permit any of its
officers, directors, employees, representatives or Affiliates) solicit,
encourage, hire or take any other action which is intended to induce or
encourage, or has the effect of inducing or encouraging any Retained Employee to
terminate his or her employment with Buyer (or its consolidated subsidiaries).

          (b)  For a period commencing on the Closing Date and ending on the
first anniversary of the Closing Date, neither ICS nor Seller (and their
successors and assigns) shall (nor shall either Seller permit any of its
officers, directors, employees, representatives or Affiliates) solicit,
encourage, hire or take any other action which is intended to induce or
encourage, or has the effect of inducing or encouraging any employee of Buyer
other than the Retained Employees to terminate his or her employment with Buyer
(or its consolidated subsidiaries).

                                     -33-
<PAGE>
 
          (c)  If, in any judicial proceeding, a court refuses to enforce the
covenants (or any part thereof) set forth above, then such unenforceable
covenant (or such part) shall be eliminated from this Agreement to the extent
necessary to permit the remaining separate covenants (or portions thereof) to be
enforced. In the event that the provisions of this Section 6.12 are deemed to
exceed the time, geographic or scope limitations permitted by applicable law,
then such provisions shall be reformed to the maximum time, geographic or scope
limitations, as the case may be, permitted by applicable laws.

          (d)  The Sellers acknowledge that their agreements as set forth herein
are necessary to preserve the value of the Acquired Assets for Buyer following
the Acquisition. Each Seller also acknowledges that the limitations of time, and
scope of activity agreed to in this Agreement are reasonable because, among
other things, (i) the Sellers and Buyer are engaged in a highly competitive
industry, and (ii) the Sellers are receiving significant consideration in
connection with the Acquisition.

          (e)  Each Seller agrees that it would be impossible or inadequate to
measure and calculate Buyer's damages from any breach of the covenants set forth
in this Section 6.12. Accordingly, each Seller agrees that if either of them
breaches any provision of this Section 6.12, Buyer will have available, in
addition to any other right or remedy otherwise available, the right to obtain
an injunction from a court of competent jurisdiction restraining such breach or
threatened breach and to specific performance of any such provision of this
Agreement. Each Seller further agrees that no bond or other security shall be
required in obtaining such equitable relief, nor will proof of actual damages be
required for such equitable relief. Each Seller hereby expressly consents to the
issuance of such injunctive relief, whether in the form of a temporary
restraining order or otherwise, and to the ordering of such specific
performance.

     6.13 Employment Offers.
          ----------------- 

          (a)  Buyer shall make offers to each of the Retained Employees whose
background and reference checks are deemed acceptable in the discretion of
Buyer, to enter into "at-will" employment arrangements reasonably satisfactory
to Buyer; provided, however, that nothing in this Section 6.13 shall affect in
any manner whatsoever the right or power of Buyer to terminate any such
employment relationship, for any reason, with or without cause.

          (b)  In the event, after the Closing, a Retained Employee accepts
and enters into such an "at-will" employment arrangement with Buyer, such
employee shall receive salary and benefits consistent with Buyer's current
practice, including the right to participate in Buyer's stock option plan.

    6.14  COBRA.  The Sellers, shall continue to make available COBRA

shall take any and all actions reasonably necessary and appropriate under the
Code Section 401(k) plan in which Seller is currently a participating

employer ("Seller 401(k) Plan") to permit a transfer of the account balance(s)
           ------------------ 
which are attributable to the Retained Employees, from Seller 401(k) Plan to the
3Com Corporation 401(k) Plan ("Buyer's 401(k) Plan").
                               -------------------   

     6.16 Agreement with Respect to Retained Employee's Stock Options. No later
          -----------------------------------------------------------  
than the Closing, ICS will offer to each optionee under an ICS Option to amend
each ICS Option such that (i) the vested portion of each ICS Option shall remain
exercisable until September 30, 1999, provided that in order to exercise such
vested portion after three months following the Closing, the optionee must be an
employee of Buyer or any of its subsidiaries, and (ii) the unvested portion of
each ICS Option shall (1) continue to vest until September 30, 1999 to the same
extent that such ICS Option would have vested had the optionee remained employed
with ICS or its subsidiaries and (2) be exercisable at any time or from time to
time from October 1, 1999 through October 31, 1999, to the extent then vested,
if at the time of any such exercise the optionee is an employee of Buyer or any
of its subsidiaries. The form and substance of such amendment is subject to the
review and approval of the Buyer.

     6.17 ICS Lease.  Promptly following the date of this Agreement and
          --------- 
continuing until the earlier of the termination of this Agreement or the
Closing, ICS and Buyer will negotiate in good faith the terms of a lease (the
"ICS Lease") for premises reasonably required by Buyer in the Building (as
 ---------
defined in Exhibit D hereto). In the event the parties do not come to agreement
           --------- 
on the terms of the ICS Lease on or before the Closing Date, the Short Term
Occupancy Agreement set forth on Exhibit D (the "Occupancy Agreement") shall go
                                 ---------       ------------------- 
into effect upon the Closing and shall govern the landlord-tenant relationship
between ICS and Buyer, and the terms of the Occupancy Agreement shall constitute
a contract between ICS and Buyer. If ICS completes the Sale Lease-Back prior to
the Closing, then (a) the ICS Lease or Occupancy Agreement, as the case may be,
shall become a sublease in which ICS is the sublessor and Buyer is the
sublessee, with such additional modifications as shall be necessary and
reasonably acceptable to ICS and Buyer, (b) ICS shall immediately provide to
Buyer a true and complete copy of such lease and a certificate certifying that
the representations set forth in Section 3.12 with respect to such lease are
true and (c) Schedule 3.12(a) shall be modified to include such lease. This
Section 6.17 shall survive for one (1) year following the Closing.

     6.18 Additional Documents and Further Assurances.  Each party hereto, at
          -------------------------------------------                        
the request and expense of another party hereto, shall execute and deliver such
other instruments and do and perform such other acts and things as may be
necessary or desirable for effecting completely the consummation of this
Agreement and the transactions contemplated hereby.

claim or claims made in any Officer's Certificate within thirty (30) days after
delivery of such Officer's Certificate, the indemnifying party and indemnified
party shall attempt in good faith to agree upon the rights of the respective
parties with respect to each of such claims. If the indemnifying party and
indemnified party should so agree, a memorandum setting forth such agreement
shall be prepared and signed by all such parties.

          (b)    If no such agreement can be reached after good faith
negotiation, either the indemnifying party or the indemnified party may demand
arbitration of the matter unless the amount of the damage or loss is at issue in
pending litigation with a third party, in which event arbitration shall not be
commenced until such amount is ascertained or both parties agree to arbitration;
and in either such event the matter shall be settled by arbitration as provided
in Section 10.7. Within thirty (30) days of any entry of a decision of the
arbitrator(s) requiring payment by an indemnifying party to an indemnified party
pursuant to this Article VIII and Section 10.7, the indemnifying party shall
make the payment to indemnified party.

     8.6  Third-Party Claims.  In the event an indemnified party becomes aware 
          ------------------                                            
of a third-party claim which it believes will be covered by the indemnification
and/or defense obligation contained in this Article VIII, it shall notify the
indemnifying party of such claim, and the indemnifying party shall be entitled,
at its expense, to participate in the defense of such action and to assume
control of such defense; provided, however, that:

          (a)  the indemnified party shall be entitled to participate in the
defense of such claim and to employ counsel at its own expense to assist in the
handling of such claim;

          (b)  the indemnifying party shall obtain the prior written approval of
the indemnified party before entering into any settlement of such claim or
ceasing to defend against such claim, if, pursuant to or as a result of such
settlement or cessation, injunctive or other equitable relief would be imposed
against the indemnified party;

          (c)  the indemnifying party shall not consent to the entry of any
judgment or enter into any settlement that does not include as an unconditional
term thereof the giving by the claimant or

                                     -39-
<PAGE>
 
plaintiff to each indemnified party of a release from liability in respect of
such claim without the prior written consent of the indemnifying party, which
consent shall not be unreasonably withheld;

          (d)  the indemnified party shall not admit any liability with respect
thereto or settle, compromise, pay or discharge the same without the prior
written consent of the indemnifying party, which consent shall not be
unreasonably withheld;

          (e)  the indemnified party shall cooperate with the indemnifying party
in the contest or defense thereof; and

          (f)  the indemnifying party shall not be entitled to control but shall
be entitled to participate at its own expense in the defense of, and the
indemnified party shall be entitled to have sole control at its own expense
over, the defense or settlement of any claim to the extent the claim seeks an
order, injunction or other equitable relief against the indemnified party which,
if successful, could materially interfere with the business, operations, assets,
condition or prospects of the indemnified party.

          After written notice by the indemnifying party to the indemnified
party of its election to assume control of the defense of any such action, the
indemnifying party shall not be liable to such indemnified party hereunder for
any legal fees and expenses subsequently incurred by such indemnified party in
connection with the defense thereof. If the indemnifying party does not assume
control of the defense of such claims as provided in this Section 8.5, the
indemnified party shall have the right to defend such claim in such manner as it
may deem appropriate at the reasonable cost and expense of the indemnifying
party.

     8.7  Indemnification Limitations.  Notwithstanding anything to the
          ---------------------------                                  
contrary in this Agreement, (a) there shall be no liability for indemnification
by the Sellers, on the one hand, or by the Buyer, on the other hand, under this
Article VIII unless and to the extent that the aggregate amount of damages
claimed for Losses against Sellers or Buyer, as the case may be, exceeds
$400,000; and (b) the aggregate liability of the Sellers or Buyer, as the case
may be, in respect of indemnifiable Losses shall not exceed the total amount of
the Purchase Price paid to Sellers hereunder. Indemnification pursuant to this
Article VIII shall be the exclusive remedy for any Losses for which
indemnification may be sought under Section 8.2 or 8.3. For purposes of
calculating the amount of Losses incurred by Buyer arising out of any breach or
inaccuracy of any representation or warranty made by either Seller contained
herein, the reference to a "Material Adverse Effect" or materiality (or other
correlative terms) shall be disregarded.

     8.8  Computation of Losses.  Anything in this Agreement to the contrary
          ---------------------                                             
notwithstanding, the amount of any Losses otherwise payable to an indemnified
party shall be reduced by the amount of net insurance proceeds received by the
indemnified party (giving effect to deductible or self-insured or co-insurance
payments made and the costs, if any, of obtaining such insurance proceeds by the
indemnified party) as compensation for the damage or Losses caused by the act,
omission, fact or circumstance giving rise to the Losses; provided, however,
that no indemnified party shall be obligated to seek such insurance proceeds.

the Business or (ii) compel Buyer or either Seller to dispose of or hold
separate all or a portion of the Acquired Assets, the Business or other assets
of either Seller or Buyer as a result of the Acquisition;

warranty, covenant or agreement contained in this Agreement on the part of
either Seller and such breach has not been cured within ten (10) calendar days
after written notice to the Sellers, as appropriate; provided, however, that, no
cure period shall be required for a breach which by its nature cannot be cured;

          (e) by the Sellers if neither Seller is in material breach of their
respective obligations under this Agreement and there has been a material breach
of any representation, warranty, covenant or agreement contained in this
Agreement on the part of Buyer and such breach has not been cured within ten
(10) calendar days after written notice to Buyer; provided, however, that no

as provided in Section 9.1, this Agreement shall forthwith become void and there

used herein shall be deemed in each case to be followed by the words "without
limitation." The table of contents and headings contained in this Agreement are
for reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

     10.3 Counterparts.  This Agreement may be executed in one or more
          ------------                                                
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other party, it being understood that all
parties need not sign the same counterpart.

     10.4 Entire Agreement; Assignment.  This Agreement, the Exhibits hereto,   
          ----------------------------                                       
the Schedules, the Confidentiality Agreement, the Related Agreements (upon their
execution and delivery), and the documents and instruments and other agreements
among the parties hereto referenced herein: (a) constitute the entire agreement
among the parties with respect to the subject matter hereof and 

                                     -43-
<PAGE>
 
supersede all prior agreements and understandings both written and oral, among

     10.5 Severability.  In the event that any provision of this Agreement or 
          ------------

jurisdiction to be illegal, void or unenforceable, the remainder of this
Agreement will continue in full force and effect and the application of such
provision to other Persons or circumstances will be interpreted so as reasonably
to effect the intent of the parties hereto. The parties further agree to replace
such void or unenforceable provision of this Agreement with a valid and
enforceable provision that will achieve, to the extent possible, the economic,
business and other purposes of such void or unenforceable provision.

such party, and the exercise by a party of any one remedy will not preclude the
exercise of any other remedy.

     10.7 Governing Law; Arbitration.  This Agreement shall be governed by and
          --------------------------                                      
construed in accordance with the laws of the State of California, regardless of
the laws that might otherwise govern under applicable principles of conflicts of
laws thereof. Any claim or dispute arising out of or related to this Agreement,
or the interpretation, making, performance, breach or termination thereof, shall
be finally settled by binding arbitration in Santa Clara County, California
under the rules of the American Arbitration Association then in effect by a
single arbitrator mutually agreeable to Buyer, Seller and ICS. In the event that
within forty-five (45) days after the submission of any dispute to arbitration,
Buyer, Seller and ICS cannot mutually agree on a single arbitrator, Buyer, on
the one hand, and Seller and ICS, on the other hand, shall each select one
arbitrator and the AAA shall select a third arbitrator. The arbitrator(s) shall
have the authority to grant any equitable and legal remedies that would be
available in any judicial proceeding instituted to resolve a dispute. Judgment
on the award rendered by the arbitrators may be entered in any court having
jurisdiction thereof. The arbitrator(s) may award to the prevailing party, if
any, as determined by the arbitrator(s), all of its costs and fees, including
AAA administrative fees, arbitrator fees, attorney's fees, expert fees, witness
fees, travel expenses and out-of-pocket expenses (including such expenses as
copying, telephone, facsimile, postage and courier fees). The parties to the
arbitration may apply to any court of competent jurisdiction for a temporary
restraining order, preliminary injunction or other interim or conservatory
relief, as necessary, without breach of this arbitration provision and without
any abridgement of the powers of the arbitrator(s). The parties agree that, any
provision of applicable law notwithstanding, they will not request and the
arbitrator(s) shall have no authority to award punitive or exemplary damages
against any party.

     10.8 Rules of Construction.  The parties hereto agree that they have been
          ---------------------                                          
represented by counsel during the negotiation and execution of this Agreement
and, therefor, waive the application of 

                                     -44-
<PAGE>
 
any law, regulation, holding or rule of construction providing that ambiguities
in an agreement or other document will be construed against the party drafting
such agreement or document.

     10.9 No Third Party Beneficiaries.  This Agreement shall not confer any
          ----------------------------                                      
rights or remedies upon any Person other than the parties hereto and their
respective successors and permitted assigns.
