                             TCSI Corporation
     Notes to Pro Forma Condensed Consolidated Financial Information
            For the nine months ended September 30, 1996 and
                   for the year ended December 31, 1995

1.   Description of transaction

     TCSI  Corporation  operates in one segment which  provides  integrated
     software products and services for the global telecom industry.

     On November 14, 1996, TCSI Corporation (the "Registrant") entered into
     an  Asset  Purchase  and  License  Agreement  with  Atmel  Corporation
     ("Atmel")  pursuant to which Atmel purchased the assets  and  licensed
     the   intellectual  property  associated  with  the  business  of  the
     Registrant's Personal Communications Group ("PCG").  The PCG  business
     consists  of  developing  and implementing  a  portfolio  of  software
     products   for   communications  semiconductor  applications.    Atmel
     delivered 335,000 shares of Atmel's Common Stock to the Registrant  as
     the negotiated consideration pursuant to the Agreement.

     The  value  of  the  Common  Stock  received  by  the  Registrant  was
     approximately  $10  million.  Costs associated with  this  transaction
     approximated $2 million.

2.   Basis of presentation

     The  accompanying  pro  forma financial statements  are  presented  to
     provide information on the impact of the disposition of assets to  the
     results  of operations of the Registrant.  Pro forma income statements
     have  been provided for the nine months ended September 30,  1996  and
     the  year  ended December 31, 1995 as if  the disposition had occurred
     on  January 1, 1996 and 1995, respectively.  A pro forma balance sheet
     has  not been provided because the effect from the disposition on  the
     Registrant's consolidated financial position was not significant.

     Pro  forma adjustments to the historical financial information include
     adjustments  to  remove  all revenues and  the  direct  costs  of  the
     services and licensing provided for the Registrant's PCG business.  No
     other  adjustments to costs and expenses are presented as  the  effect
     from  the  disposition  was not determinable  because  the  Registrant
     operates  in  one segment.  All pro forma adjustments  to  the  income
     statements  assume  that  the  disposition  was  consummated  at   the
     beginning of each of the periods presented.

     The  pro forma financial statements should be read in conjunction with
     the  Registrant's  financial  statements in  the  Registrant's  Annual
     Report on Form 10-K for 1995 and in the Registrant's Form 10-Q for the
     nine  months ended September 30, 1996.  The pro forma information does
     not  purport to represent what the Registrant's results of  operations
     would have been had operations been conducted without the Registrant's
     PCG business during the periods covered or to project the Registrant's
     results of operations for any future period.

3.   Pro forma adjustments

     Pro  forma  adjustments  related to the income  statements  have  been
     provided assuming the disposition was consummated on January 1 of  the
     respective  periods.  Pro forma income statements adjustments  are  as
     follows:

     (A)  Adjustment to reflect total revenues without revenues related to
          the Registrant's PCG business.

     (B)  Adjustment to reflect direct cost of services without direct cost
          of services related to the Registrant's PCG business.

or license is obtained and to cooperate with Buyer in any reasonable
arrangement (such as subcontracting, sublicensing or subleasing) designed

Asset (including enforcement of any such agreement for the benefit of
Buyer) and any and all rights of Seller arising out of the breach or
cancellation of such Acquired Asset.

     1.4  Assumption of Liabilities.

          (a)  Buyer shall not assume any liabilities or obligations of
Seller except for those liabilities and obligations which Buyer expressly
assumes pursuant to this Section 1.4. Without limiting the foregoing, it is
expressly agreed that Buyer shall not assume any liabilities for (i)
employment, income, sales (other than as contemplated by Section 2.3),
property or other taxes incurred or accrued by Seller, whether or not
relating to the Acquired Assets, or (ii) any accrued salary, vacation,
severance, health benefits or any other employee benefits pertaining to
employees of Seller who are made offers of employment by Buyer. Seller will
indemnify and hold Buyer harmless from and against any and all losses,
costs, expenses, claims, liabilities, deficiencies, judgments and damages
incurred or suffered by Buyer or any of its affiliates related to or
arising out of any liabilities or obligations of Seller, except for those
liabilities or obligations expressly assumed by Buyer in this Section 1.4
and Section 2.3.

          (b)  Effective from and after the Closing, Buyer shall assume and
agree to pay, discharge or perform, as appropriate, (i) Seller's
obligations under the Assigned Contracts listed on Schedule 1.2(g) attached
hereto, (ii) the sales taxes payable by Buyer pursuant to Section 2.3,
(iii) all liabilities and obligations listed on Schedule 1.4 attached
hereto and (iv) any and all liabilities and obligations relating to the
ownership, use or operation of the Acquired Assets by Buyer arising after
the Closing (collectively, the "Assumed Liabilities"), provided that Buyer
shall have no obligation pursuant to any of the Assigned Contracts or the
liabilities and obligations listed on Schedule 1.4 attached hereto which by
their terms require a consent to assignment unless and until such consent
is obtained or Buyer and Seller have reached a reasonable arrangement in
writing with respect to such obligations in accordance with Section 1.3.

     1.5  Intellectual Property License.

          (a)  In conjunction with the transfer and assignment of the
Acquired Assets and subject to the conditions contained herein, on the
Closing Date Seller hereby grants to Buyer an perpetual, irrevocable,
worldwide exclusive license (including as against Seller and its
affiliates) in its Intellectual Property (defined below); provided however,
that such license shall be subject to and shall not impair all existing
licenses of such Intellectual Property.  In conjunction with the foregoing
license, Seller agrees to execute, at Buyer's expense, such instruments and
documents as Buyer may reasonably request.  "Intellectual Property" means
all patents, patent applications, copyrights, trademarks, service marks,
trade names, trade secrets, proprietary information, technology rights and
licenses, proprietary rights and processes, know-how, research and
development in progress, and any and all other intellectual property
including, without limitation, all things authored, discovered, developed,
made, perfected, improved, designed, engineered, devised, acquired,
produced, conceived or first reduced to practice by Seller or any of its
employees in the course of their employment by Seller and that pertain to
or are used in connection with the activities of the PCG Business, or that
are relevant to the development of the PCG Business or to the performance
by the products of the PCG Business of their intended functions or
purposes, whether tangible or intangible, in any stage of development,
including without limitation enhancements, designs, technology,
improvements, inventions, works of authorship, formulas, processes,
routines, subroutines, techniques, concepts, object code, flow charts,
diagrams, coding sheets, source code, listings and annotations,
programmers' notes, information, work papers, work product and other
materials of any types whatsoever, and all rights of any kind in or to any
of the foregoing. Notwithstanding the foregoing, "Intellectual Property"
shall not include (i) any Intellectual Property that contains proprietary
information of Seller's customers or (ii) third party software that
prohibits the transfer of such software.  In addition, subject to Article
7, it is agreed that Seller shall be permitted to utilize the Intellectual
Property solely to the extent reasonably necessary to satisfy its
obligations under the Customer Contracts.

<PAGE> 17

          (b)  If Buyer obtains any proprietary information of Seller's
customers pursuant to this Agreement, Buyer shall hold such information
confidential, refrain from using such information and delivery such
information promptly to Seller.

          (c)  Seller agrees not to modify, amend or expand the provisions
of any existing Intellectual Property licenses without the prior consent of
Buyer, which consent shall not be unreasonably withheld.  Seller agrees
promptly to forward to Buyer all future royalty payments received by Seller
under its existing licensing agreements.

          (d)  As security for Buyer's license in the Intellectual Property
described in Section 1.5(a), Seller hereby grants to Buyer a security
interest in the Intellectual Property covered by such license.  Seller
shall assist Buyer in executing and filing the necessary uniform commercial
code statements and continuation statements relating to the perfection of
such security interest.

          (b)  Adjustment of Buyer's Shares.  If, between the date of this
Agreement and the Closing Date, the outstanding shares of Buyer's Common
Stock shall have been changed into a different number of shares or a
different class by reason of any recapitalization, stock dividend, split-
up, combination, exchange of shares or readjustment, the number of Buyer's
Shares shall be correspondingly adjusted.

          (c)  Fractional Shares.  No fractional shares of Buyer's Common
Stock shall be issued, but in lieu thereof Seller shall receive from Buyer
an amount of cash equal to the value of the fractional share.

     2.2  Closing

               (a)  Date.  The Closing under this Agreement (the "Closing")
shall be held on November 14, 1996, provided that the conditions precedent
specified in this Agreement have been satisfied.  Such date on which the
Closing is to be held is herein referred to as the "Closing Date."  The
Closing shall be held at the offices of Wilson, Sonsini, Goodrich & Rosati,
650 Page Mill Road, Palo Alto, California, at 10:00 A.M. on such date, or
at such other time and place as Buyer and Seller may agree upon in writing.

          (b)  Closing Deliveries.  At the Closing, Buyer shall deliver
either the certificate(s) representing the Buyer's Shares registered in
Seller's name and in such denominations as Seller may reasonably request or
a copy of its letter to the Buyer's transfer agent requesting the issuance

transfer documents as Buyer may reasonably request, with the transfer
thereunder being effective without further action on November 18, 1996.  On
November 18, 1996, Seller, through its officers, agents and employees, will
put Buyer into full possession and enjoyment of all tangible Acquired
Assets, terms FOB Seller.  At the Closing, Seller shall commence delivery
to Buyer of those Acquired Assets identified by Buyer to be delivered by
remote telecommunication or such other method as Buyer in its sole
discretion directs.

          (c)  Delivery.  At the Closing or the time otherwise indicated:

               (i)  Buyer shall deliver to Seller an instrument of
assumption of liabilities in substantially the form of Exhibit A hereto by
which Buyer shall assume the Assumed Liabilities as of the Closing;

                (ii) Seller shall deliver to Buyer all bills of sale,
endorsements, assignments, consents to assignments to the extent obtained
and other instruments and documents as Buyer may reasonably request to

          (d)  Taking of Necessary Action; Further Action.  If, at any time
after the Closing Date, any further action is necessary or desirable to
carry out the purposes of this Agreement and to vest Buyer with full right,
title and possession to all the Acquired Assets, and all property, rights,
privileges, powers and franchises of Seller relating thereto, the officers
of Seller are fully authorized in the name Seller or otherwise to take, and
will take, all such lawful and necessary and/or desirable action.

     2.3  Sales and Use Taxes.  The sales, use and transfer taxes arising
out of the transfer of the Acquired Assets (the "Transfer Taxes"), shall be
determined at Closing based on the Allocation described in Section 2.4 and
shall be borne equally by Buyer and Seller.  To the extent permitted by
law, Seller and Buyer shall cooperate fully in minimizing Transfer Taxes,
which the parties hereto estimate (based on a preliminary analysis of the
assets to be transferred) to be approximately $100,000.  To the extent a
taxing authority provides notice to Seller of an audit of the Transfer
Taxes, Seller shall immediately notify Buyer and Buyer and Seller shall
jointly assume responsibility for such audit and each of Buyer and Seller
shall pay when due 50% of any additional Transfer Taxes (plus interest and
penalties) ultimately assessed with respect to the transactions
contemplated by this Agreement.  Buyer and Seller shall have joint
authority to control, settle or defend any proposed adjustment to the
Transfer Taxes and Buyer and Seller shall cooperate fully in the defense or
settlement of any proposed adjustment to Transfer Taxes.

     2.4  Allocation.  The purchase price and license fee shall be
allocated in accordance with Schedule 2.4. Each of the parties hereto
agrees to report this transaction for state and federal tax purposes in
accordance with such allocation.

are specifically disclosed in the disclosure schedule supplied by Seller to
Buyer (the "Disclosure Schedule"), as of the date hereof and as of the
Closing Date as follows:

<PAGE> 20

     3.1  Organization of Seller.  Seller is a corporation duly
incorporated and validly existing under the laws of the State of Nevada and
has full corporate power and authority to carry on the PCG Business as it
is now being conducted and to own the Acquired Assets.  Seller is duly
qualified or licensed to do business as a foreign corporation in good
standing in every jurisdiction in which the ownership of the Acquired
Assets or the conduct of the PCG Business requires such qualification,
except where the failure to so qualify or be licensed would not have a
material adverse effect on the business or financial condition of the PCG
Business.

     3.2  Due Authorization.  Seller has the corporate power and authority
to execute and deliver this Agreement, and each document, instrument or
agreement contemplated hereby, including but not limited to the documents
delivered at Closing, and to perform its obligations hereunder and
thereunder. The execution, delivery and performance of this Agreement and
each document, instrument or agreement executed pursuant to this Agreement
by Seller and the consummation of the transactions contemplated hereby and
thereby have been duly authorized by all necessary corporate action.

     3.3  Due Execution and Enforceability.  This Agreement, and each
document, instrument or agreement executed pursuant to this Agreement by
Seller, including but not limited to the documents delivered at Closing,
have been duly executed and delivered by Seller, and assuming due
authorization, execution and delivery by Buyer, this Agreement and each
document, instrument or agreement executed pursuant to this Agreement by
Seller, including but not limited to the documents delivered at Closing,
constitute the legal, valid and binding obligations of Seller, enforceable
against Seller in accordance with their terms.

     3.4  No Conflict.  The execution and delivery of this Agreement, and
each document, instrument or agreement executed pursuant to this Agreement,
including but not limited to the documents delivered at Closing, and the
performance of Seller's obligations hereunder and thereunder, (i) are not
in violation or breach of, and will not conflict with or constitute a
default under, any of the terms of the articles of incorporation or bylaws
of Seller, or, except as provided in Schedule 1.2(g), any material
contract, agreement or commitment binding upon Seller or any of the
Acquired Assets; and (ii) will not, to the best knowledge of Seller,
conflict with or violate any applicable law, rule, regulation, judgment,
order or decree of any government, governmental instrumentality or court
having jurisdiction over Seller or any of the Acquired Assets.

     3.5  Consents and Approvals of Governmental Authorities.  No consent,
approval or authorization of, or declaration, filing or registration with,
any governmental or regulatory authority is required to be made or obtained
by Seller in connection with the execution, delivery and performance of
this Agreement and each document, instrument and agreement executed
pursuant to this Agreement.

     3.6  Seller Financial Statements6  Seller Financial Statements.
Schedule 3.6 sets forth the PCG's statement of income for the nine-month
period ended September 30, 1996 (the "PCG Financials").  The PCG Financials
have been prepared in good faith applied on a basis consistent throughout
the period indicated and generally consistent with the Seller's
consolidated financial statements.  The PCG Financials present fairly the
operating results of the PCG Business during the period indicated therein,
subject to normal year-end consolidation adjustments, which are not
material.  Seller does not maintain separate divisional balance sheets.

     3.7  Proprietary Rights and Ownership7  Proprietary Rights and
Ownership.

          (a)  Ownership.  Subject to Schedules 1.2(g) and 1.3, Seller owns
or possesses licenses or other rights to use the Acquired Assets and the
intellectual property licensed pursuant to Section 1.5 (collectively
referred to as "Proprietary Rights") and has the rights to sell, assign,
transfer, license and deliver, as applicable, such Proprietary Rights as
contemplated herein.

          (b)  No Infringement.  Except as set forth in Schedules 3.7 and
3.11 attached hereto, to the best knowledge of Seller, the Proprietary
Rights do not infringe, and no one has asserted to Seller that such rights
infringe, any proprietary rights owned, possessed or used by any third
party.  Except as set forth on Schedule 3.7, there are no claims, disputes,
actions, proceedings, suits or appeals pending against Seller with respect
to any Proprietary Rights and, to the knowledge of Seller, none has been
threatened against Seller.  Except as set forth in Schedules 3.7 and 3.11,
to the best knowledge of Seller, there are no facts or alleged facts which
would reasonably serve as a basis for any claim that Seller does not have
the right to use, free of any rights or claims of others, all Proprietary
Rights in the design, development, manufacture, use, sale and other
disposition of any or all products in the PCG Business and services
presently being used, furnished or sold in the conduct of the business of
the PCG Business as it has been and is now being conducted.

          (c)  Effective Transfer of Necessary Rights.  Except as set forth
in Schedules 1.3, 3.7 and 3.11, by means of this Agreement, together with
the documents, instruments and agreements contemplated hereby, Seller will
transfer to Buyer good and marketable title to all Acquired Assets and the
related Proprietary Rights.  Except as set forth in Schedules 1.3, 3.7 and
3.11, by means of the license in Section 1.5, together with the documents,
instruments and agreements contemplated thereby, Seller will transfer to
Buyer a good and valid license to the Intellectual Property and the related
proprietary rights covered thereby. Except as set forth in Schedules 1.3
and 3.7, the Acquired Assets and the related proprietary rights sold to
Buyer pursuant to this Agreement and the Intellectual Property and related
Proprietary rights licensed to Buyer pursuant to this Agreement, and the
documents, instruments and agreements contemplated hereby and thereby, will
transfer all necessary assets and intellectual property rights required by
Buyer to conduct the PCG Business.

     3.8  Restrictions on Business Activities.  Except on Schedule 3.8,
there is no agreement, commitment, judgment, injunction, order or decree
binding upon Seller, the Acquired Assets or, to Seller's knowledge, any
employee of Seller, which has or could reasonably be expected to have the
effect of prohibiting or impairing in any material respect any use by Buyer
of the Acquired Assets following the Closing to the extent used in the
manner generally used prior to the Closing Date.

<PAGE> 22

     3.9  Capital Equipment and Hard Assets.  All tangible assets and
equipment listed on Schedule 1.2(a) are in substantially good condition and
repair and are adequate for the uses to which they are being put or would
be put in the ordinary course of business consistent with industry
standards; all of the tangible assets will be transferred to Buyer without
any liens or encumbrances.

     3.10 Title to Assets.

          (a)  Schedule 3.10(a) sets forth a list of all real property
currently leased by Seller relating to the Acquired Assets, the name of the
lessor, the date of the lease and each amendment thereto and the aggregate
annual rental and/or other fees payable under any such lease.  All such
current leases are in full force and effect, are valid and effective in
accordance with their respective terms, and there is not, under any of such
leases, any existing default or event of default (or event which with
notice or lapse of time, or both, would constitute a default).

          (b)  Seller has good and valid title to, or, in the case of
leased properties, valid leasehold interests in, all of the Acquired
Assets, free and clear of any Liens, except as reflected in Schedule
3.10(b).

     3.11 Intellectual Property.

          (a)  Seller owns a valid right or license to use the Intellectual
Property being used or held for use to conduct the activities of the PCG
Business, and to the best knowledge of Seller the conduct of the activities
of the PCG Business currently and in the past does not conflict with and
has not conflicted with Intellectual Property rights of others.  Except as
set forth on Schedule 3.11, all Intellectual Property used or held for use
in the conduct of the activities of the PCG Business owned by Seller is so
owned free and clear of all Liens and no other person, including without
limitation any present or former employee, officer or director of Seller,
has any right whatsoever therein. To the best knowledge of Seller, neither
Seller nor any present or former employee thereof has violated or, by
conducting the activities of the PCG Business in the ordinary course
consistent with past practice would violate, any of the Intellectual
Property rights of any other person or entity.  Seller does not have any
obligation to compensate any person or entity for the use of any
Intellectual Property relating to the Acquired Assets.  Except as set forth
in Schedule 3.11, Seller has not granted to any person or entity any
license, option or other rights to use in any manner any Intellectual
Property relating to the Acquired Assets whether requiring the payment of
royalties or not.

          (b)  Except as set forth on Schedule 3.11, Seller has all right,
title and interest in and to the software products and the software
technology and related documentation included in the Acquired Assets (the
"Software").  Except as set forth on Schedule 3.11, no person or entity
other than Seller owns any right, title or interest in the Software
including, without limitation, any right to manufacture, use, copy,
distribute or sublicense any object code or source code thereof.  Except as
set forth on Schedule 3.11, the Software is (i) not subject to any Liens,
(ii) not subject to any pending or, to Seller's best knowledge, threatened
challenge of infringement of the rights of others, nor to the best
knowledge of Seller is there any basis for a challenge of infringement of
any such rights of others, and (iii) freely transferable and assignable to
Buyer.

     3.12 Contracts.  Each of the Assigned Contracts referred to on
Schedule 1.2(g) to this Agreement, except as set forth in Schedule 1.2(g),
is a legal, binding and enforceable obligation by or against Seller,
subject to the effect of applicable bankruptcy, insolvency, reorganization,
moratorium or other similar federal or state laws affecting the rights of
creditors and the effect or availability of rules of law governing specific
performance, injunctive relief or other equitable remedies (regardless of
whether any such remedy is considered in a proceeding at law or in equity).
Except as set forth in Schedule 1.2(g), Seller 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 agreement required
to be set forth in Schedule 1.2(g).  Each Assigned Contract is in full
force and effect and, except as otherwise disclosed in Schedule 1.2(g), is
not subject to any default thereunder of which Seller has knowledge by any
party obligated to Seller pursuant thereto.  Seller has obtained, or will
obtain prior to the Closing Date, all necessary consents, waivers and
approvals of parties to any Assigned Contract as are required to assign all
rights and benefits thereunder to Buyer as of the Closing.

     3.13 Governmental Authorization. Schedule 3.13 accurately lists each
material consent, license, permit, grant or other authorization issued to
Seller by a Governmental Entity (i) pursuant to which Seller currently
operates or holds any interest in any of the Acquired Assets or (ii) which
is required for the operation of the activities of the PCG Business or the
holding of any such interest (herein collectively called "PCG
Authorizations"), which PCG Authorizations are in full force and effect and
constitute all PCG Authorizations required to permit Seller to operate or
conduct the activities of the PCG Business or hold any interest in the
Acquired Assets.  No Governmental Entity has at any time notified Seller of
any challenge or question regarding the legal right of Seller to
manufacture, offer or sell any of the products of the PCG Business in the
present manner or style thereof.

     3.14 Compliance with Applicable Laws.  Seller has complied in all
material respects with all laws, regulations, rules and orders (including
those relating to environmental matters) of each court, administrative
agency or commission or other governmental authority or instrumentality,
domestic or foreign (each a "Governmental Entity") applicable to it which
relate to the Acquired Assets, except where the failure to so comply would
not, individually or in the aggregate, reasonably be expected to have a
material adverse effect on the PCG Business. Except as set forth in
Schedule 3.14, Seller has not received any written notice of any asserted
violation of any such laws, regulations, rules or orders.  Seller has not
received any written notice that any investigation or review by any
Governmental Entity with respect to the PCG Business is pending or that any
such investigation or review is contemplated, except where the outcome of
such investigation or review would not have a material adverse effect on
the business or financial condition of the PCG Business.

     3.15 Reliance Upon Seller's Representations.  Seller understands that
the Buyer's Shares are not registered under the Securities Act on the
ground that the sale provided for in this Agreement and the issuance of
securities hereunder is exempt from registration under the Securities Act
pursuant to section 4(2) thereof, and that the Buyer's reliance on such
exemption is based on Seller's representations set forth in the
Shareholders Agreement attached hereto as Exhibit F.

     3.16 Material Adverse Effect16     Material Adverse Effect. There is
no fact, circumstance or condition of any kind or nature whatsoever known
to Seller which reasonably would be expected to have a material adverse
effect on the PCG Business or Acquired Assets that has not been set forth
in this Agreement and the Schedules hereto, except those facts concerning
general economic, legislative, regulatory or other matters such as may
generally impact all businesses of the type operated by Seller.

     3.17 Taxes.  To the extent a failure to do so would materially and
adversely affect Buyer, the Acquired Assets or Buyer's use of the Acquired
Assets, (i) Seller has timely filed within the time the period for filing
or any extension granted with respect thereto, all federal, state, local
and foreign tax returns, reports and estimates ("Returns") which it is
required to file relating or pertaining to any and all taxes attributable
to or levied upon the Acquired Assets, and (ii) paid any and all taxes it
is required to pay in connection with the taxable periods to which such
Returns relate.  There are (and immediately following the Closing there
will be) no Liens or similar encumbrances on the Acquired Assets relating
or pertaining to taxes, except with respect to taxes not yet due and
payable.  Seller has no knowledge of any basis for the assertion of any
material claims which, if adversely determined, would result in a Lien or
other encumbrance on the Acquired Assets or otherwise materially and
adversely affect Buyer or the Acquired Assets.

     3.18 Brokers' or Finders' Fees. Seller is not a party to, or in any
way obligated under, and has no knowledge of, any contract or outstanding
claim for the payment of any broker's or finder's fee in connection with
the origin, negotiation, execution or performance of this Agreement, the
nonpayment of which could result in the placement of a lien or other
encumbrance on the Acquired Assets, or a claim against Buyer or its
affiliates.

document, instrument or agreement executed pursuant to this Agreement by
Buyer, including but not limited to the documents to be delivered at
Closing, constitute the legal, valid and binding obligations of Buyer,
enforceable against Buyer in accordance with their terms.

     4.4  No Conflict.  The execution and delivery of this Agreement and
each document, instrument or agreement executed pursuant to this Agreement,
including but not limited to the documents to be delivered at Closing, and

                                ARTICLE 5

                COVENANTS RELATING TO CONDUCT OF BUSINESS

     During the period from the date of this Agreement and continuing until
the Closing Date, Seller agrees (except as expressly contemplated by this
Agreement or to the extent that Buyer shall otherwise consent in writing)
that:

     5.1  Ordinary Course.  Seller shall carry on the business of the PCG
Business in the usual, regular and ordinary course, including the payment
of all state and federal taxes, in substantially the same manner as
heretofore conducted and, to the extent consistent with such business, use
all commercially reasonable efforts consistent with past practice and
policies to preserve intact the PCG Business's present business
organization, will use its reasonable efforts to keep available the
services of the PCG Business's present key employees and preserve the PCG
Business's relationships with present and potential customers, suppliers
and others having business dealings with the PCG Business to the end that
the PCG Business's goodwill and ongoing businesses shall be unimpaired at
the Closing; provided, however that Seller shall not without Buyer's
express written consent enter into any long-term supply or volume purchase
commitments.

     5.2  No Dispositions.  Seller shall not sell, lease, encumber or
otherwise dispose of any of the assets of the PCG Business, individually or

neither Seller nor Buyer will furnish any communication to its shareholders
or to the public generally if the subject matter thereof relates to the
other party or to the transactions contemplated by this Agreement without
the prior approval of the other party as to the content thereof, which
approval shall be prompt and not be unreasonably withheld, and subject to
each party's compliance with applicable law.

<PAGE> 27

     6.2  Update to Disclosures.  Without limiting either party's right to
rely on the representations and warranties as set forth herein, each of
Buyer and Seller shall provide the other party with updates to the
disclosures provided or made available to the other party as to material
facts which arise between the date of this Agreement and the Closing Date
and which, if they had occurred and been known prior to the date of this
Agreement, would have been required to have been disclosed in order to make
the representations and warranties contained in Article 3 and Article 4
true and correct as of the date of this Agreement.

     6.3  Good Faith; Further Assurances.  Each party shall act in good
faith in an attempt to cause to be satisfied the conditions precedent to
this Agreement, including obtaining any consent or license identified in
Schedule 1.3.  Each party will act in good faith and take all reasonable
action to include all items on Schedules 1.2(a)-(n) to this Agreement which
were intended by the parties to be so included therein to the extent they
are discovered after the date hereof and before the Closing Date and to
take all reasonable action within its capability necessary to render
accurate as of the Closing Date its representations and warranties
contained in this Agreement.  Each party, upon the request of the other
party from time to time after Closing, shall execute and deliver, and use
their reasonable efforts to cause other persons to execute and deliver, to
the other party all such further documents and instruments, and will do or
use their reasonable efforts to cause to be done such other acts, as either
party may reasonably request, more completely to consummate and make
effective the transactions contemplated hereby.  After the Closing Date,
Seller shall endeavor in good faith to provide, consistent with any
contractual limitations, the information required by Buyer necessary to
understand and enforce the rights it may have with respect to Intellectual
Property under the Customer Contracts.

     6.4  PCG Business Transition.  Buyer and Seller shall use their best
efforts to finalize a transition plan as soon as reasonably practicable
following the date hereof. Buyer agrees to perform the obligations under
the Customer Contracts retained by Seller as described in Schedule 6.4.
Seller agrees to provide within 30 days after the Closing Date a schedule
(a "Requirements Schedule") setting forth in reasonable detail an estimate
of the man-hours and other efforts required to complete such obligations.
Promptly after the beginning of each month following delivery of the
initial Requirements Schedule, Seller shall deliver to Buyer a revised
Requirements Schedule in form and scope consistent with the initial
Requirements Schedule.  As compensation for such services, Seller agrees
that Buyer shall receive the compensation specified in Schedule 6.4 (it
being understood that Buyer shall be obligated to pay for any direct costs
related to earning such compensation up to the amount of such
compensation).  If the actual man-hours and efforts required of Buyer to
complete the Schedule 6.4 obligations are in excess of from those set forth
in the initial Requirements Schedule, Buyer and Seller shall negotiate in
good faith to provide additional fair compensation to Buyer.

     6.5  Provision of Audited Financials.  The parties acknowledge that
audited financials have never been prepared and are not currently available

and regulations of the SEC to file, or include in any filing otherwise
required to be filed by it under the Exchange Act, historical audited
financial statements (the "Financial Statements") of the PCG Business or
the Acquired Assets, then Buyer shall notify Seller in writing of such
requirement and provide a detailed statement of all financial statements so
required by Buyer. Seller shall cause its independent auditors to assist
Buyer in preparing such Financial Statements, provided that Buyer shall pay
all of the reasonable fees charged and disbursements incurred by Seller's
independent auditors in connection with the preparation of such Financial
Statements.  In connection with any claim for reimbursement, Seller shall
provide Buyer with a copy of the auditor's invoice (including such fees and
disbursements).  Buyer shall promptly pay such invoice after receipt
thereof.

Shareholder Agreement in the form attached hereto as Exhibit F, which will
become effective upon the Closing.

     6.7  Transition Plan; PCG Employees.   Promptly after Closing, Buyer
will make offers of employment to the PCG employees of Seller who are
identified on Schedule 6.7 hereto.  Such offers of employment will provide
that the employees will have an "at will" employment relationship
(commencing on and after November 18, 1996) with Buyer and will be entitled
to participate in the employee benefit plans generally available to Buyer's
employees.  The Buyer shall not assume, and the Seller shall indemnify
Buyer against, any and all obligations of Seller to such persons accepting
employment with Buyer arising as a result of their employment with Seller
prior to November 18, 1996 including, without limitation, all obligations
and liabilities related to salary, commissions, bonus or other performance-
based compensation, accrued vacation, severance or any other employee
benefits of any kind whatsoever.

accountants, counsel and other representatives, full access during normal

Seller's properties, books, commitments and records relating to the
Acquired Assets, (b) the employees and suppliers of the PCG Business and
(c) all other information concerning the business, properties and personnel

retain any and all information regarding the PCG Business operations on or
prior to the Closing Date necessary for Buyer to calculate the availability
to it of tax credits for research activities under Section 41 of the
Internal Revenue Code of 1986.  Seller agrees to provide to Buyer and its
accountants, counsel and other representatives copies of internal financial
statements promptly upon request.  No informa tion or knowledge obtained in
any investigation pursuant to this Section 6.8 shall affect or be deemed to
modify any representation or warranty contained herein or the conditions to
the obligations of the parties hereunder.

<PAGE> 29

     6.9  Confidentiality.  Each of the parties hereto hereby agrees to
keep such information or knowledge obtained in any investigation pursuant
to Sections 2.3 or 6.8, or pursuant to the negotiation and execution of

confidential; provided, however, that the foregoing shall not apply to
information or knowledge which (a) a party can demonstrate was already
lawfully in its possession prior to the disclosure thereof by the other
party, (b) is generally known to the public and did not become so known
through any violation of law or this Agreement, (c) became known to the
public through no fault of such party, (d) is later lawfully acquired by

Exchange Act or (h) any press release that describes the general provisions
of the Agreement and is mutually acceptable to Buyer and Seller.

     6.10 Patent Property.  With respect to all patent rights, patents and
patent applications constituting part of the Acquired Assets (the
"Transferred Patents"), at the request of Buyer, Seller shall use all
reasonable efforts to assist Buyer in the preparation, filing, prosecution,
and maintenance of the Transferred Patents at Buyer's expense except for
the value of time of Seller's employees.  To the extent that any named
inventors of the Transferred Patents remain employees of Seller, Seller
shall use reasonable efforts to make the named inventors available to Buyer
for the purposes of preparing, filing, prosecuting, and maintaining
Transferred Patents.

     6.11 Taxes.  Subject to Section 2.3, Seller shall be responsible for
and pay when due all taxes attributable to or levied or imposed upon the
Acquired Assets relating or pertaining to the period (or that portion of
any period) ending on or prior to the Closing Date.  Subject to Section
2.3, Seller shall continue to timely file within the time period for
filing, or any extension granted with respect thereto, all tax returns
required to be filed in connection with the Acquired Assets.

     6.12      GSM Agreement.  Buyer and Seller agree that the GSM contract
between Buyer and Seller shall be canceled upon the Closing without any
further action on the part of Buyer and Seller.

     In consideration for the amount received under this Agreement, from

period commencing on the Closing Date and ending on the completion of the
fifth (5th) full year after the Closing Date:

of the outstanding voting securities of such company as to a publicly-
traded company, or ten percent (10%) as to a private company; or

          (d)  Otherwise engage, or participate in any business or entity
that engages or participates in the design, development, production,
marketing, sales or service of any product that competes with products of
the PCG Business.

It is understood that the sale of products and services not competing with
the products of the PCG Business to entities otherwise engaged or
participating in a business which competes with the PCG Business shall not
violate the provisions of this Article 7.  This covenant not to compete
shall terminate immediately and automatically in the event that the Buyer
shall no longer engage in the PCG Business.  This covenant not to compete
shall not apply to Seller's use of the Intellectual Property solely to the
extent reasonably necessary to satisfy its obligations under the Customer
Contracts retained by Seller.

     SURVIVAL OF REPRESENTATIONS AND WARRANTIES; INDEMNITY; ESCROW

     9.1  Survival of Representations and Warranties.  All of Buyer's and
Seller's representations and warranties in this Agreement or in any
instrument delivered pursuant to this Agreement (each as modified by the
Disclosure Schedules) shall survive the Closing and continue until 5:00
p.m., California time until the date which is one year following the date
of this Agreement (the "Expiration Date").

     9.2  Indemnification by Buyer. Except as otherwise expressly provided
in this Article 9, Buyer shall defend, indemnify and hold harmless each of
Seller and its directors, officers and affiliates (collectively, "Buyer
Indemnitees"), and shall reimburse Buyer Indemnitees, for, from and against
each and every claim, loss (which shall include any diminution in value),
liability, judgment, damage, cost and expense (including, without
limitation, interest, penalties, costs of preparation and investigation,
and the reasonable fees, disbursements and expenses of attorneys,
accountants and other professional advisors) (collectively, "Loss" or
"Losses") imposed on or incurred by Buyer Indemnitees resulting from or
arising out of (including without limitation, resulting from or arising out
of any claim made by any third party) (a) a breach of Buyer's
representations, warranties or covenants in this Agreement, (b)
transactions, events, acts or omissions of or by Buyer relating to the
Acquired Assets after the Closing or (c) the Assumed Liabilities.

     9.3  Indemnification by Seller. Except as otherwise expressly provided
in this Article 9, Seller shall defend, indemnify and hold harmless each of
Buyer and its directors, officers and affiliates (collectively, "Seller
Indemnitees"), and shall reimburse Seller Indemnitees, for, from and

Seller's representations, warranties or covenants in this Agreement or (b)
transactions, events, acts or omissions of or by Seller relating to the
Acquired Assets on or before the Closing.

<PAGE> 33

     9.4  Notice and Defense of Third-Party Claims.  If any action, claim
or proceeding shall be brought or asserted under this Article 9 against any
Buyer Indemnitee or Seller Indemnitee (in either case, an "Indemnified
Person") in respect of any claim by a third party for which indemnity may
be sought under this Article 9 from an indemnifying person or any successor
thereto (the "Indemnifying Person"), the Indemnified Person shall give
prompt written notice of such action or claim to the Indemnifying Person
who shall assume the defense thereof, including the employment of counsel
reasonably satisfactory to the Indemnified Person and the payment of all
expenses; except that any delay or failure so to notify the Indemnifying
Person shall relieve the Indemnifying Person of its obligations hereunder
only to the extent, if at all, that (A) it is prejudiced by reason of such
delay or failure, or (B) the Indemnified Person fails to give notice of its
claim.  The Indemnified Person shall have the right to employ separate
counsel in any of the foregoing actions, claims or proceedings and to
participate in the defense thereof, but the fees and expenses of such
counsel shall be at the expense of the Indemnified Person unless both the
Indemnified Person and the Indemnifying Person are named as parties and the
Indemnified Person shall in good faith determine that representation by the
same counsel is inappropriate. In the event that the Indemnifying Person,
within thirty (30) days after notice of any such action or claim, fails to
assume the defense thereof, the Indemnified Person shall have the right to
undertake the good faith defense of such action, claim or proceeding for
the account of and at the expense of the Indemnifying Person, subject to
the right of the Indemnifying Person to assume the defense of such action,
claim or proceeding at any time prior to the settlement, compromise or
final determination thereof.  Anything in this Article 9 to the contrary
notwithstanding, (a) the Indemnifying Person shall not, without the
Indemnified Person's prior written consent, settle or compromise any action
or claim or consent to the entry of any judgment with respect to any
action, claim or proceeding for anything other than money damages paid by
the Indemnifying Person, and (b) the Indemnified Party shall not settle or
compromise any action or claim or consent to the entry of any judgment,
except where the Indemnifying Person has failed to assume the defense of
such action or claim, and then only with the prior consent of the
Indemnifying Party, which shall not be unreasonably withheld.  The
Indemnifying Person may, without the Indemnified Person's prior consent,
settle or compromise any such action, claim or proceeding or consent to
entry of any judgment with respect to any such action or claim that
requires solely the payment of money damages by the Indemnifying Person.

     9.5  Limitation of Remedies.  Buyer acknowledges and agrees that
absent fraud its sole and exclusive remedy with respect to any and all
claims relating to the subject matter of this Agreement shall be pursuant
to the indemnification provisions set forth in this Article 9.  In
furtherance of the foregoing, Buyer hereby waives, absent fraud by Seller,
any and all rights, claims and causes of action it may have against Seller

ordinance, rule or regulation (including, without limitation, any such
relating to environmental matters or arising under or based upon common law
or otherwise).

     9.6  Minimum; Maximum.  Notwithstanding the other provisions of this

     9.7  Escrow Arrangements.

          (a)  Escrow Fund.  Within one business day of the Closing, Seller
shall deposit, in respect of a portion of the purchase price, $1,000,000 in
cash (the "Escrow Account") with the Escrow Agent (defined below) as
partial security for the indemnity obligations of Seller hereunder. The
Escrow Amount will be deposited with Bank of America, (or other institution
acceptable to Buyer and Seller) as Escrow Agent (the "Escrow Agent"), such
deposit to constitute an escrow fund (the "Escrow Fund") to be governed by
the terms set forth herein and at Buyer's cost and expense.  The Escrow
Fund shall be available as partial security for the indemnity obligations
of Seller set forth in this Article 9 and shall constitute Buyer's initial
remedy with respect to such indemnity obligations.  Buyer may not receive
any funds from the Escrow Fund unless and until Officer's Certificates (as
defined in paragraph (d) below) identifying Losses, the aggregate amount of
which exceed $75,000, have been delivered to the Escrow Agent as provided
in paragraph (e); in such case, Buyer may recover from the Escrow Fund the
total of its Losses, including the first $75,000.

          (b)  Escrow Period; Distribution upon Termination of Escrow
Periods.  Subject to the following requirements, the Escrow Fund shall be
in existence immediately following the Effective Time and shall terminate
at 5:00 p.m., California time, on the sixth month anniversary of the
Closing Date (the "Escrow Period"); provided that the Escrow Period shall
not terminate with respect to such amount (or some portion thereof), that
together with the aggregate amount remaining in the Escrow Fund is
necessary  in the reasonable judgment of Buyer, subject to the objection of
Seller and the subsequent arbitration of the matter in the manner provided
in Section 9.7(f) hereof, to satisfy any unsatisfied claims concerning
facts and circumstances existing prior to the termination of such Escrow
Period specified in any Officer's Certificate delivered to the Escrow Agent
prior to termination of such Escrow Period.  As soon as all such claims
have been resolved, the Escrow Agent shall deliver to Seller the remaining
portion of the Escrow Fund not required to satisfy such claims.

          (c)  Protection and Investment of Escrow Fund.

               (i)  The Escrow Agent shall hold and safeguard the Escrow
Fund during the Escrow Period, shall treat such fund as a trust fund in
accordance with the terms of this Agreement and not as the property of
Buyer and shall hold and dispose of the Escrow Fund only in accordance with
the terms hereof.

               (ii) The Escrow Fund shall be invested by the Escrow Agent
from time to time (x) in securities which at the date of such investments
are direct obligations of, or obligations fully guaranteed by, the United
States or any agency of the United States or bank certificates of deposit
of a United States bank which is an affiliate of the Federal Reserve System
and has a net worth of at least $100,000,000, in each case with maturities
not in excess of 30 days,  (y) in securities of corporate issuers having a
short- term a credit rating in the two highest rating categories as
determined by Moody's Investors Services or Standard & Poor's designated in
writing by Seller to the Escrow Agent or (z) in such securities as Buyer
and Seller shall mutually designate in writing delivered to the Escrow
Agent.  Any interest received with respect to such investments of the
Escrow Fund shall be added to and shall constitute part of the Escrow Fund.
The Escrow Agent shall have the right to sell securities in order to make
payments and shall not be liable for any loss due to fluctuation in market
value or penalties due to early redemption.

<PAGE> 35

          (d)  Claims Upon Escrow Fund.

          Upon receipt by the Escrow Agent at any time on or before the
last day of the Escrow Period of a certificate signed by any officer of
Buyer (an "Officer's Certificate"): (A) stating that Buyer has paid or
properly accrued or reasonably anticipates that it will have to pay or
accrue Losses, and (B) specifying in reasonable detail the individual items
of Losses included in the amount so stated, the date each such item was
paid or properly accrued, or the basis for such anticipated liability, and
the nature of the misrepresentation, breach of warranty or covenant to
which such item is related, the Escrow Agent shall, subject to the
provisions of Section 9.7(e) hereof, deliver to Buyer out of the Escrow
Fund, as promptly as practicable, an amount held in the Escrow Fund equal
to such Losses.

          (e)  Objections to Claims.  At the time of delivery of any
Officer's Certificate to the Escrow Agent, a duplicate copy of such
certificate shall be delivered to Seller and for a period of thirty (30)
days after such delivery, the Escrow Agent shall make no delivery to Buyer
of any Escrow Amounts pursuant to Section 9.7(d) hereof unless the Escrow
Agent shall have received written authorization from Seller to make such
delivery.  After the expiration of such thirty (30) day period, the Escrow
Agent shall make delivery of funds from the Escrow Fund in accordance with
Section 9.7(d) hereof, provided that no such payment or delivery may be
made if Seller shall object in a written statement to the claim made in the
Officer's Certificate, and such statement shall have been delivered to the
Escrow Agent prior to the expiration of such thirty (30) day period.

          (f)  Resolution of Conflicts; Arbitration.

               (i)  In case Seller shall so object in writing to any claim
or claims made in any Officer's Certificate, Seller and Buyer shall attempt
in good faith to agree upon the rights of the respective parties with
respect to each of such claims.  If Seller and Buyer should so agree, a
memorandum setting forth such agreement shall be prepared and signed by
both parties and shall be furnished to the Escrow Agent.  The Escrow Agent
shall be entitled to rely on any such memorandum and distribute amounts
from the Escrow Fund in accordance with the terms thereof.

<PAGE> 36

               (ii) If no such agreement can be reached after good faith
negotiation, either Buyer or Seller 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 conducted by
three arbitrators. Buyer and Seller shall each select one arbitrator, and
the two arbitrators so selected shall select a third arbitrator.  The
arbitrators shall set a limited time period and establish procedures
designed to reduce the cost and time for discovery while allowing the
parties an opportunity, adequate in the sole judgment of the arbitrators,
to discover relevant information from the opposing parties about the
subject matter of the dispute.  The arbitrators shall rule upon motions to
compel or limit discovery and shall have the authority to impose sanctions,
including attorneys' fees and costs, to the extent as a court of competent
law or equity, should the arbitrators determine that discovery was sought
without substantial justification or that discovery was refused or objected
to without substantial justification.  The decision of a majority of the
three arbitrators as to the validity and amount of any claim in such
Officer's Certificate shall be binding and conclusive upon the parties to
this Agreement, and notwithstanding anything in Section 9.7(e) hereof, the
Escrow Agent shall be entitled to act in accordance with such decision and
make or withhold payments out of the Escrow Fund in accordance therewith.
Such decision shall be written and shall be supported by written findings
of fact and conclusions which shall set forth the award, judgment, decree
or order awarded by the arbitrators.

               (iii)      Judgment upon any award rendered by the
arbitrators may be entered in any court having jurisdiction.  Any such
arbitration shall be held in Santa Clara County, California under the rules
then in effect of the American Arbitration Association.  For purposes of
this Section 9.7(f), in any arbitra tion hereunder in which any claim or
the amount thereof stated in the Officer's Certificate is at issue, Buyer
shall be deemed to be the Non-Prevailing Party in the event that the
arbitrators award Buyer less than one-half (1/2) of the disputed amount
plus any amounts not in dispute; otherwise, Seller shall be deemed to be
the Non-Prevailing Party.  The Non-Prevailing Party to an arbitration shall
pay its own expenses, the fees of each arbitrator, the administrative costs
of the arbitration and the expenses, including without limitation,
reasonable attorneys' fees and costs, incurred by the other party to the
arbitration.

          (g)  Third-Party Claims.  In the event Buyer becomes aware of a
third-party claim which Buyer believes may result in a demand against the
Escrow Fund, Buyer shall notify Seller of such claim, and Seller shall be
entitled, at its expense, to participate in any defense of such claim.
Buyer shall have the right in its sole discretion to settle any such claim;
provided, however, that except with the consent of Seller, no settlement of
any such claim with third-party claimants shall alone be determinative of
the amount of any claim against the Escrow Fund.  In the event that Seller
has consented to any such settlement, Seller shall have no power or
authority to object under any provision of this Article 9 to the amount of
any claim by Buyer against the Escrow Fund with respect to such settlement.

          (h)  Escrow Agent's Duties.

               (i)  The Escrow Agent shall be obligated only for the
performance of such duties as are specifically set forth herein, and as set
forth in any additional written escrow instructions which the Escrow Agent
may receive after the date of this Agreement which are signed by an officer
of Buyer and Seller, and may rely and shall be protected in relying or
refraining from acting on any instrument reasonably believed to be genuine
and to have been signed or presented by the proper party or parties.  The
Escrow Agent shall not be liable for any act done or omitted hereunder as
Escrow Agent while acting in good faith and in the exercise of reasonable
judgment, and any act done or omitted pursuant to the advice of counsel
shall be conclusive evidence of such good faith.

<PAGE> 37

               (ii) The Escrow Agent is hereby expressly authorized to
comply with and obey orders, judgments or decrees of any court of law,
notwithstanding any notices, warnings or other communications from any
party or any other person to the contrary. In case the Escrow Agent obeys
or complies with any such order, judgment or decree of any court, the
Escrow Agent shall not be liable to any of the parties hereto or to any
other person by reason of such compliance, notwithstanding any such order,
judgment or decree being subsequently reversed, modified, annulled, set
aside, vacated or found to have been entered without jurisdiction.

               (iii)     The Escrow Agent shall not be liable in any
respect on account of the identity, authority or rights of the parties
executing or delivering or purporting to execute or deliver this Agreement
or any documents or papers deposited or called for hereunder.

               (iv) The Escrow Agent shall not be liable for the expiration
of any rights under any statute of limitations with respect to this
Agreement or any documents deposited with the Escrow Agent.

               (v)  In performing any duties under the Agreement, the
Escrow Agent shall not be liable to any party for damages, losses, or
expenses, except for gross negligence or willful misconduct on the part of
the Escrow Agent.  The Escrow Agent shall not incur any such liability for
(A) any act or failure to act made or omitted in good faith, or (B) any
action taken or omitted in reliance upon any instrument, including any
written statement or affidavit provided for in this Agreement that the
Escrow Agent shall in good faith believe to be genuine, nor will the Escrow
Agent be liable or responsible for forgeries, fraud, impersonations, or
determining the scope of any representative authority.  In addition, the
Escrow Agent may consult with the legal counsel in connection with Escrow
Agent's duties under this Agreement and shall be fully protected in any act
taken, suffered, or permitted by him/her in good faith in accordance with
the advice of counsel.  The Escrow Agent is not responsible for determining
and verifying the authority of any person acting or purporting to act on
behalf of any party to this Agreement.

<PAGE> 38

               (vi) If any controversy arises between the parties to this
Agreement, or with any other party, concerning the subject matter of this
Agreement, its terms or conditions, the Escrow Agent will not be required
to determine the controversy or to take any action regarding it.  The
Escrow Agent may hold all documents and Escrow Fund, and may wait for
settlement of any such controversy by final appropriate legal proceedings
or other means as, in the Escrow Agent's discretion, the Escrow Agent may
be required, despite what may be set forth elsewhere in this Agreement.  In
such event, the Escrow Agent will not be liable for damage. Furthermore,
the Escrow Agent may at its option, file an action of interpleader
requiring the parties to answer and litigate any claims and rights among
themselves.  The Escrow Agent is authorized to deposit with the clerk of
the court all documents and amounts held in escrow, except all cost,
expenses, charges and reasonable attorney fees incurred by the Escrow Agent
due to the interpleader action and which the parties jointly and severally
agree to pay. Upon initiating such action, the Escrow Agent shall be fully
released and discharged of and from all obligations and liability imposed
by the terms of this Agreement.

               (vii)     The parties and their respective successors and
assigns agree jointly and severally to indemnify and hold Escrow Agent
harmless against any and all losses, claims, damages, liabilities, and
expenses, including reasonable costs of investigation, counsel fees, and
disbursements that may be imposed on Escrow Agent or incurred by Escrow
Agent in connection with the performance of its duties under this
Agreement, including but not limited to any litigation arising from this
Agreement or involving its subject matter.

               (viii)    The Escrow Agent may resign at any time upon
giving at least thirty (30) days written notice to the parties; provided,
however, that no such resignation shall become effective until the
appointment of a successor escrow agent which shall be accomplished as
follows:  the parties shall use their best efforts to mutually agree on a
successor escrow agent within thirty (30) days after receiving such notice.
If the parties fail to agree upon a successor escrow agent within such
time, the Escrow Agent shall have the right to appoint a successor escrow
agent authorized to do business in the State of California.  The successor
escrow agent shall execute and deliver an instrument accepting such
appointment and it shall, without further acts, be vested with all the
estates, properties, rights, powers, and duties of the predecessor escrow
agent as if originally named as escrow agent.  The Escrow Agent shall be
discharged from any further duties and liability under this Agreement.

          (i)  Fees.  All fees of the Escrow Agent for performance of its
duties hereunder shall be paid by Buyer.  It is understood that the fees
and usual charges agreed upon for services of the Escrow Agent shall be
considered compensation for ordinary services as contemplated by this
Agreement.  In the event that the conditions of this Agreement are not
promptly fulfilled, or if the Escrow Agent renders any service not provided
for in this Agreement, or if the parties request a substantial modification
of its terms, or if any controversy arises, or if the Escrow Agent is made
a party to, or intervenes in, any litigation pertaining to this escrow or
its subject matter, the Escrow Agent shall be reasonably compensated for
such extraordinary services and reimbursed for all costs, attorney's fees,
and expenses occasioned by such default, delay, controversy or litigation.
Buyer promises to pay these sums upon demand.

                           ASSUMPTION AGREEMENT
     
     
     This ASSUMPTION AGREEMENT is made, executed and delivered as of the
14th day of November 1996 and effective as of the 18th day of November
1996, by and between TCSI Corporation, a Nevada corporation (the "Seller"),
and Atmel Corporation, a California corporation (the "Buyer").
     
     
                           W I T N E S S E T H
     
     WHEREAS, by Bill of Sale being executed and delivered by the Seller to
the Buyer simultaneously herewith pursuant to an Asset Purchase and License
Agreement between the Seller and the Buyer dated November 14th, 1996 (the
"Agreement"), the Seller is selling, conveying, assigning, transferring and
delivering to the Buyer all of the Acquired Assets (capitalized terms used
but not otherwise defined herein shall have the meaning set forth in the
Agreement), for the consideration, in the amount and upon the terms and
subject to the conditions contained in the Agreement; and
     
     WHEREAS, in consideration therefor, the Agreement requires that the
Buyer undertake to assume and to agree to perform, pay or discharge certain
limited obligations of the Seller.
     
     NOW, THEREFORE,
     
     1.   In consideration of the sale, conveyance, assignment, transfer
and delivery of the Acquired Assets by Seller to Buyer, the Buyer hereby
undertakes, assumes and agrees to perform, to the extent not heretofore
performed, the Assumed Liabilities, as described in Section 1.4 of the
Agreement.
     
     2.   The assumption by the Buyer of an obligation of the Seller shall
not be construed to defeat, impair or limit, in any way, any rights, or
remedies of the Buyer to contest or dispute in good faith the validity or
amount thereof.
     
     3.   Other than as specifically set forth above and in the Agreement,
the Buyer assumes no liability of the Seller of any kind, character or
description, including without limitation, liabilities based on tort,
contract or other claims.
     
     4.   Buyer agrees to indemnify and hold Seller, and its directors,
officers, and affiliates, harmless against and in respect of any loss,
cost, expense (including expenses of investigation), claim, liability,
deficiency, judgment or damage, including reasonable legal and accounting
fees and expenses incurred by Seller, its officers, directors, or
affiliates, by reason of Buyer's failure to satisfy or discharge in a
timely manner any of the Assumed Liabilities.  This provision does not

                          SHAREHOLDER AGREEMENT
     
     THIS AGREEMENT is made and entered into as of November 14, 1996,
between Atmel Corporation, a California corporation ("Atmel"), and TCSI
Corporation, a Nevada  corporation ("TCSI"). All capitalized terms used and
not otherwise defined herein shall have the meanings given them in the
Purchase Agreement.
     
                                RECITALS:
     
     Atmel and TCSI have entered into an Asset Purchase Agreement dated as
of  November 13, 1996 (the "Purchase Agreement") which provides for the
sale by TCSI of the Acquired Assets to Atmel in exchange for 335,000 shares
of Common Stock of Atmel (the "Atmel Stock").  The Atmel Stock to be so
issued has not been registered under the Securities Act of 1933, as amended
("Securities Act") in reliance upon the exemption therefrom provided by in
Section 4(2) of the Securities Act.
     
     In consideration of the premises and the mutual representa tions,
warranties and covenants herein contained, the parties hereto have agreed
and do hereby agree as follows:
     
     1.   Restricted Stock; Legend.
     
          1.1  Each certificate for shares of Atmel Stock shall be stamped
or otherwise imprinted with a legend stating in substance:
     
     "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED.  SUCH SHARES ARE SUBJECT TO
AND MAY NOT BE SOLD, OFFERED FOR SALE, TRANSFERRED, ASSIGNED, OR OTHERWISE
DISPOSED OF EXCEPT (I) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT
RELATED THERETO, (II) IN COMPLIANCE WITH RULE 144 OR (III) PURSUANT TO AN
OPINION OF COUNSEL FOR THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED
UNDER THE SECURITIES ACT OF 1933."
     
          1.2  In connection with the limitations on disposition with
respect to the Atmel Stock contained in this Agreement, Atmel will issue
stop transfer instructions to its transfer agent with respect to such
shares.
     
          1.3  TCSI understands that Atmel is under no obligation to
register the sale, transfer or other disposition of Atmel Stock, except as
specifically provided in this Agreement.
     
<PAGE> 54
     
          1.4  In connection with any sales by TCSI of the shares of Atmel
Stock in compliance with the limitations on disposition set forth in this
Agreement, Atmel agrees to notify  its transfer agent that the legend set
forth in Section 1.1 may be removed from such shares of Atmel Stock being
sold by TCSI at the time of such sales.
     
     2.   TCSI's Representations.  TCSI represents, warrants and covenants
to Atmel that:
     
          2.1  The Purchase Agreement has been made with TCSI in reliance
upon TCSI's representation to Atmel, which by TCSI's execution of this
Agreement TCSI hereby confirms, that the Atmel Stock to be acquired by TCSI
will be acquired for investment for TCSI's own account, not as a nominee or
agent, and not with a view to the resale or distribution of any part
thereof.
     
          2.2  TCSI understands that the shares of Atmel Stock to be issued
under the Purchase Agreement are not registered under the Securities Act on
the ground that the sale provided for in the Purchase Agreement and the
issuance of securities hereunder is exempt from registration under the
Securities Act of 1933, as amended (the "Securities Act") pursuant to
Section 4(2) thereof, and that Atmel's reliance on such exemption is based
on TCSI's representations set forth herein.
     
          2.3  TCSI believes it has received all the information it
considers necessary or appropriate for deciding whether to acquire the
Atmel Stock.  TCSI further represents that it has had an opportunity to ask
questions and receive answers from Atmel regarding the business,
properties, prospects and financial condition of Atmel and to obtain
additional information necessary to verify the accuracy of any information
furnished to it or to which it had access.
     
          2.4  TCSI is experienced in evaluating and investing in
securities and acknowledges that is able to fend for itself, can bear the
economic risk of acquiring the Atmel Stock, and has such knowledge and
experience in financial and business matters that it is capable of
evaluating the merits and risks of acquiring the Atmel Stock.
     
          2.5  TCSI understands that the Atmel Stock may not be sold,
transferred or otherwise disposed of without registration under the
Securities Act or an exemption therefrom, and that in the absence of an
effective registration statement covering such shares or an available
exemption from registration under the Securities Act, such shares must be
held indefinitely.  TCSI covenants that, except to the extent the
restrictions set forth in Section 1.1 are waived by Atmel, TCSI shall not
transfer the shares represented by any such certificate without complying
with the restrictions on transfer described in such legend.  TCSI agrees to
provide Atmel with notice of any sale of Atmel Stock no later than
immediately prior to placing an order with a broker or, if not sold through
a broker, at the time of closing an agreement to sell such shares, and, to
the extent practicable, TCSI will use its best efforts to provide Atmel 48
hours advance notice of any such sale.
     
<PAGE> 55
     
          2.6  TCSI will not make any sale, transfer, or other disposition
of Atmel Stock unless (i) such sale, transfer, or other disposition is
within the limitations of and in compliance with Rule 144 under the
Securities Act, or (ii) some other exemption from registration under the
Securities Act is available with respect to any such proposed sale,
transfer or other disposition of Atmel Stock, or (iii) such distribution of
Atmel Stock has been registered under the Securities Act.
     
          2.7  TCSI is aware of Atmel's business affairs and financial
condition and has sufficient information about Atmel to reach an informed
and knowledgeable decision to acquire the Atmel Stock in the transaction
contemplated by the Purchase Agreement. TCSI acknowledges it has previously
received Atmel's Annual Report to Shareholders for the fiscal year ended
December 31, 1995, a copy of its Annual Report on Form 10-K for the fiscal
year ended December 31, 1995, and a copy of its Quarterly Report on Form 10-
Q for the three and nine month periods ended September 30, 1996, and that
it has had the opportunity to receive additional information concerning
Atmel.  TCSI is acquiring the Atmel Stock for investment and not with a
view to resale or distribution.
     
          2.8  TCSI agrees to accurately complete and execute the
Questionnaire attached hereto as Exhibit A as promptly as possible after
receipt from Atmel of the draft of the Form S-3 registration statement
contemplated to be filed as set forth in Section 4 of this Agreement, and
in any case, prior to Atmel's filing of such Form S-3.
     
     3.   Transfers of Atmel Stock.  With respect to any disposition or
attempted disposition of any shares of Atmel Stock, TCSI will comply with
the following procedure:
     
          3.1  With respect to any sale of Atmel Stock made pursuant to
Rule 144, TCSI will provide Atmel with copies of appropriate documentation
evidencing compliance with Rule 144.
     
          3.2  With respect to a proposed disposition of Atmel Stock not
registered under the Securities Act and other than pursuant to Rule 144,
TCSI will give prior written notice to Atmel describing the manner and
circumstances of the proposed disposition in sufficient detail to enable
Atmel to evaluate whether the proposed disposition of such shares satisfies
the requirements of the Securities Act and this Agreement.  Upon receipt of
such written notice, Atmel shall promptly notify TCSI either (i) that the
Atmel Stock may be disposed of in the manner and under the circumstances
described, or (ii) that on the basis of the information provided the Atmel
Stock may not be disposed of prior to the receipt by Atmel of an opinion of
counsel reasonably satis factory to Atmel and its counsel to the effect
that the proposed disposition of Atmel Stock may be effected without
registration under the Securities Act, or in lieu thereof, a "no action"
letter or other communication from the Commission reasonably satisfactory
to Atmel and its counsel to that effect.
     
          3.3  With respect to a disposition of Atmel Stock registered
under the Securities Act, TCSI will dispose of such Common Stock as
provided in the Form S-3 registration statement.
     
     4.   Registration Rights.

<PAGE> 57
     
               (a)  Upon receipt of any notice from Atmel of (i) the
happening of any event which makes any statements made in the registration
statement or related prospectus filed pursuant to this Section 4, or any
documents incorporated or deemed to be incorporated therein by reference,
untrue in any material respect or which requires the making of any changes
in such registration statement or prospectus so that, in the case of such
registration statement it will not contain any untrue statement of a
material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein not misleading, and
that in the case of the prospectus, it will not contain any untrue
statement of a material fact or omit to state a material fact necessary in

sixty (60) days, disposition of such Atmel Stock covered by such
registration statement or prospectus until it is advised in writing by
Atmel that use of the applicable prospectus may be resumed, and has
received copies of any additional or supplemental filings that are

Atmel shall use its reasonable efforts to insure that the use of the
prospectus may be resumed as soon as practicable.
     
               (b)  TCSI shall provide all such information and materials
to Atmel and take all such action as may be required in order to permit
Atmel to comply with all applicable requirements of the Commission and to
obtain any desired acceleration of the effective date of such registration
statement.  Such provision of information and materials is a condition
precedent to the obligations of Atmel pursuant to this Agreement.  TCSI
will effect the sale of the Registrable Securities through Alex. Brown &
Sons Incorporated or other broker to be selected by TCSI with the approval
of Atmel, which approval will not be unreasonably withheld.  The offerings
made pursuant to such registration shall not be underwritten.
     
          4.3  Registration and Selling Expenses.  For purposes of this
Section 4, "Registration Expenses" means all expenses incurred in

registration, filing and qualification fees, printing expenses, transfer
agent and registration fees, and fees and disbursements of counsel for

may reasonably request in connection with the registration referred to in
this Section 4.  In connection with the preparation and filing of the
registration statement under the Securities Act pursuant to this Agreement,
Atmel will give TCSI and its counsel the opportunity to participate in the
preparation of such registration statement, each prospectus included
therein or filed with the Commission, and each amendment thereof or

such registration statement for 90 days; (iii) furnish to TCSI such number
of copies of any prospectus (including any preliminary prospectus and any
amended or supplemented prospectus) in conformity with the requirements of

to file a general consent to service of process in any such jurisdiction
where it has not been qualified).
     
          5.2  Atmel shall notify TCSI, (A) when a prospectus or any
prospectus supplement or post-effective amendment has been filed, and, with
respect to the registration statement or any post- effective amendment,

the Commission or any other federal or state governmental authority of any
stop order suspending the effectiveness of the registration statement or
the initiation of any proceedings for that purpose, (D) of the receipt by
Atmel of any notification with respect to the suspension of the
qualification or exemption from qualification of any of the Registrable
Securities for sale in any jurisdiction or the initiation or threatening of
any proceeding for such purpose; or (E) of the happening of any event which
makes any statement made in the registration statement or related
prospectus or any document incorporated or deemed to be incorporated
therein by reference untrue in any material respect or which requires the
making of any changes in the registration statement or prospectus so that,
in the case of the registration

statement, it will not contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary
to make the statements therein not misleading, and that in the case of the
prospectus, it will not contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary
to make the statements therein, in the light of the circumstances under
which they were made, not misleading.  Atmel may, upon the happening of any
event (i) of the kind described in clauses B, C, D, or E hereof, or (ii)
that, in the judgment of Atmel's Board of Directors, renders it advisable
to suspend use of the prospectus for no more than sixty (60) days due to
pending corporate developments, public filings with the Commission or
similar events, suspend use of the prospectus on written notice to TCSI, in
which case TCSI shall discontinue disposition of Registrable Securities
covered by the registration statement or prospectus until copies of a
supplemented or amended prospectus are distributed to TCSI or until TCSI is
advised in writing by Atmel that the use of the applicable prospectus may
be resumed.  Atmel shall use its rea sonable efforts to ensure that the use
of the prospectus may be resumed as soon as practicable.  Atmel shall use
every reasonable effort to obtain the withdrawal of any order suspending
the effectiveness of the registration statement, or the lifting of any
suspension of the qualification (or exemption from qualification) of any of
the securities for sale in any jurisdiction, at the earliest practicable
time.  Atmel shall, upon the occurrence of any event contemplated by clause
E above, prepare a supplement or post- effective amendment to the
registration statement or a supplement to the related prospectus or any
document incorporated therein by reference or file any other required
document so that, as thereafter delivered to the purchasers of the
Registrable Securities being sold thereunder, such prospectus will not
contain an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.
     
          5.3  In connection with any offering of shares of Registrable
Securities registered on Form S-3 pursuant to this Agreement, Atmel shall
instruct the transfer agent and registrar of the Atmel Common Stock to
remove the restricted legend and release any stop transfer orders with
respect to the shares of Registrable Securities being sold.
     
          5.4  Atmel shall apply for listing on the Nasdaq National Market
the shares of Registrable Securities registered on Form S-3 pursuant to
this Agreement.
     
     6.   Availability of Form S-3.  Atmel represents that it believes it
is currently eligible to utilize Form S-3 and currently believes that there
is no material nonpublic information which would preclude it from filing a
registration statement on Form S-3.
     
     7.   Indemnification.
     
<PAGE> 60
     
          7.1  Indemnification by the Company.  To the extent permitted by
law, Atmel will indemnify and hold harmless TCSI, and each person, if any,
who controls TCSI within the meaning of the Securities Act or the Exchange
Act, against any losses, claims, damages, or liabilities (joint or several)
to which they may become subject under the Securities Act, the Exchange Act
or other federal or state law, insofar as such losses, claims, damages, or
liabilities (or actions in respect thereof) arise out of or are based upon
any of the following statements, omissions or violations (collectively a
"Violation"):  (a) any untrue statement or alleged untrue statement of a
material fact contained in a registration statement hereunder, including
any preliminary prospectus or final prospectus contained therein or any
amendments or supplements thereto, (b) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary
to make the statements therein not misleading, or (c) any violation or
alleged violation by the Company of the Securities Act, the Exchange Act,
any state securities law or any rule or regulation promulgated under the
Securities Act, the Exchange Act or any state securities law; and the
Company will pay to TCSI or such controlling person any legal or other
expenses reasonably incurred by them in connection with investigating,
defending or settling any such loss, claim, damage, liability, or action,
as such expenses are incurred; provided, however, that the indemnity
agreement contained in this Section 7.1 shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability, or action if such
settlement is effected without the consent of the Company (which consent
shall not be unreasonably withheld), nor shall the Company be liable in any
case for any such loss, claim, damage, liability, or action to the extent
that it arises out of or is based upon a Violation which occurs in reliance
upon and in conformity with written information furnished by TCSI expressly
stated for use in connection with such registration.
     
          7.2  Indemnification by TCSI.   To the extent permitted by law,
TCSI will indemnify and hold harmless the Company, each of its directors,
each of its officers who has signed the registration statement and each
person, if any, who controls the Company within the meaning of the
Securities Act, severally but not jointly, against any losses, claims,
damages, or liabilities (joint or several) to which any of the foregoing
persons may become subject, under the Securities Act, the Exchange Act or
other federal or state law, insofar as such losses, claims, damages, or
liabilities (or actions in respect thereto) arise out of or are based upon
any Violation, in each case to the extent (and only to the extent) that
such Violation occurs in reliance upon and in conformity with written
information furnished by TCSI expressly stated for use in connection with
such registration; and each TCSI will pay any legal or other expenses as
such expenses are incurred by any person intended to be indemnified
pursuant to this Section 7.2, in connection with investigating, defending
or settling any such loss, claim, damage, liability, or action; provided,
however, that the indemnity agreement contained in this Section 7.2 shall
not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of
TCSI, which consent shall not be unreasonably withheld; provided further,
that, in no event shall any indemnity by TCSI under this Section 7.2 exceed
the gross proceeds from the offering received by TCSI.
     
<PAGE> 61
     
          7.3  Indemnification Procedure.  Promptly after receipt by an
indemnified party under this Section 7 of notice of the commencement of any
action (including any governmental action), such indemnified party will, if
a claim in respect thereof is to be made against any indemnifying party
under this Section 7, deliver to the indemnifying party a written notice of
the commencement thereof and the indemnifying party shall have the right to
participate in, and, to the extent the indemnifying party so desires,
jointly with any other indemnifying party similarly noticed, to assume the
defense thereof with one counsel mutually satisfactory to the parties;
provided, however, that an indemnified party (together with all other
indemnified parties which may be represented without conflict by one
counsel) shall have the right to retain one separate counsel, with the fees
and expenses to be paid by the indemnifying party, if representation of
such indemnified party by the counsel retained by the indemnifying party
would be inappropriate due to actual or potential differing interests
between such indemnified party and any other party represented by such
counsel in such proceeding.  The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action shall not relieve such indemnifying party of any liability to the
indemnified party under this Section 7 unless the failure to deliver notice
is materially prejudicial to its ability to defend such action.  Any
omission to so deliver written notice to the indemnifying party will not
relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 7.
     
     8.   Notices.      All notices and other communications pursuant to
this Agreement shall be in writing and shall be deemed given if delivered
personally, telecopied, sent by overnight courier or mailed by registered
or certified mail (return receipt requested), postage prepaid, to the
parties at the addresses set forth below or to such other address as the
party to whom notice is to be given may have furnished to the other party

in the case of overnight courier, on the next business day after the date
when sent and (C) in the case of mailing, on the third business day
following that on which the mail containing such communication is posted:

BERKELEY, California - November 15, 1996 - TCSI Corporation (Nasdaq: TCSI),
a global provider of software to the telecom industry, today announced that
Atmel Corporation (Nasdaq: ATML) has signed an agreement to perpetually
license the intellectual property associated with TCSI's wireless
technology.  Accordingly, TCSI will no longer market this technology.  As
part of the agreement, Atmel will hire certain development and support
personnel, purchase related equipment and furniture, and perform the
support requirements of the currently installed wireless customer base.
TCSI received approximately $10 million of Atmel Common stock for this
transaction.

TCSI's wireless technology includes a portfolio of software products for
communications semiconductor applications.  The software is typically
integrated into digital signal processors (DSP) in wireless hand held
consumer products.

"Being a part of the emerging wireless industry has generally been a
rewarding and integral part of TCSI's history.  However, we believe this
agreement enables the Company to strengthen its focus on its network and
service management software technology for the telecom industry," said
Roger Strauch, TCSI's president and chief executive officer.  "We are
confident that Atmel will successfully advance the development and
deployment of sophisticated wireless solutions utilizing the intellectual
property licensed from TCSI."

"We believe that TCSI's wireless technology will complement Atmel's product
and process expertise to deliver integrated solutions to our customers in
the wireless communications market," said George Perlegos, Atmel's
president and chief executive officer.
