ITEM 5:   OTHER EVENTS.

          On February 6, 1995, Registrant entered into an Agreement and Plan of
Merger and Reorganization (the "Merger Agreement") among the Registrant, S
Acquisition Corporation, a California corporation and a wholly owned subsidiary
of the Registrant ("Merger Sub"), and Wavefront Technologies, Inc., a California
corporation ("Wavefront").  At the effective time of the merger, and subject to
and upon the terms and conditions of the Merger Agreement and California Law
(including, without limitation, approval by the stockholders of Wavefront),
Merger Sub will be merged with and into Wavefront.  As a result of the merger,
Wavefront will become a wholly owned subsidiary of the Registrant.  Subject to
the terms and conditions of the Merger Agreement, upon the effective time of the
merger, each outstanding share of common stock of Wavefront will be converted
into the right to receive 0.49 shares of common stock of the Registrant.

          Also on February 6, 1995, Registrant entered into an Agreement and
Plan of Acquisition and Arrangement (the "Acquisition Agreement") by and among
the Registrant, Silicon Graphics Manufacturing S.A., a Swiss corporation and
subsidiary of the Registrant ("Swissco"), 1103707 Ontario Inc., an Ontario
corporation and subsidiary of Swissco ("Amalgamation Sub") and Alias Research
Inc., an Ontario corporation ("Alias").  Subject to the terms and provisions of
the Acquisition Agreement and the Ontario Business Corporation Act, the
Acquisition Agreement provides for (i) the amalgamation of Amalgamation Sub and
Alias into one company (the "Continuing Corporation"), whereupon each
outstanding share of the common stock of Alias will be converted into one Class
A Share or one Class B Share (at the option of the holder and subject to
proration and certain other restrictions) of the Continuing Corporation, and
(ii) the exchange of each such Class A Share into 0.90 shares of common stock of
the Registrant and of each such Class B Share into 0.90 shares of exchangeable
non-voting shares of the Continuing Corporation (such exchangeable non-voting
shares of the Continuing Corporation to be exchangeable at the option of the
holder into shares of common stock of the Registrant on a one-for-one basis)
(the transactions specified in subclauses (i) and (ii) above being collectively
referred to herein as the "Arrangement").  As a result of the Arrangement, the
Continuing Corporation will become a subsidiary of the Registrant.

          The consummation of the Merger and the Arrangement are also each
conditioned on the concurrent closing of the other.

          The foregoing descriptions are qualified in their entirety by
reference to the full texts of the Merger Agreement and the Acquisition
Agreement, which are attached hereto as Exhibits 2.1 and 2.2, respectively, and
are incorporated herein by reference.

          Additional information concerning this event is set forth in the
Registrant's press release dated February 7, 1995, a copy of which is attached
hereto as Exhibit 99.1.

                                    ARTICLE I

                                   THE MERGERS

          SECTION 1.01.  THE MERGERS.  (a)  EFFECTIVE TIME.  At the
Effective Time (as defined in Section 1.02), and subject to and upon the terms
and conditions of this Agreement and California Law, Merger Sub shall be merged
with and into the Company, the separate corporate existence of Merger Sub shall
cease, and the Company shall continue as the surviving corporation.  The Company
as the surviving corporation after the Merger is hereinafter sometimes referred
to as the "Surviving Corporation."

          (b)  UPSTREAM MERGER.  As soon as reasonably practicable after
the Effective Time (as defined in Section 1.02), Parent shall cause the
Surviving Corporation to be merged with and into Parent (the "Upstream Merger"
and, together with the Merger, the "Mergers"), and Parent shall continue as the
surviving corporation after the Upstream Merger.

          (c)  CLOSING.  Unless this Agreement shall have been terminated
and the transactions herein contemplated shall have been abandoned pursuant to
Section 7.01 and subject to the satisfaction or waiver of the conditions set
forth in Article VI, the consummation of the Merger will take place as
promptly as practicable (and in any event within two business days) after
satisfaction or waiver of the conditions set forth in Article VI, at the offices
of Shearman & Sterling, 555 California Street, Suite 2000, San Francisco,
California, unless another date, time or place is agreed to in writing by the
parties hereto.

          SECTION 1.02.  EFFECTIVE TIME.  As promptly as practicable after
the satisfaction or waiver of the conditions set forth in Article VI, the
parties hereto shall cause the Merger to be consummated by filing articles of
merger as contemplated by Section 1103 of California Law (the "Articles of
Merger"), together with any required related certificates, with the Secretary of
State of the State of California, in such form as required by, and



<PAGE>
                                        3


executed in accordance with the relevant provisions of, California Law (the time
of such filing being the "Effective Time").

          SECTION 1.03.  EFFECT OF THE MERGER.  At the Effective Time, the
effect of the Merger shall be as provided in this Agreement, the Articles of
Merger and the applicable provisions of California Law.  Without limiting the
generality of the foregoing, and subject thereto, at the Effective Time all the
property, rights, privileges, powers and franchises of the Company and Merger
Sub shall vest in the Surviving Corporation, and all debts, liabilities and
duties of the Company and Merger Sub shall become the debts, liabilities and
duties of the Surviving Corporation.

          SECTION 1.04.  ARTICLES OF INCORPORATION; BY-LAWS.  (a)  ARTICLES
OF INCORPORATION.  Unless otherwise determined by Parent prior to the Effective
Time, at the Effective Time the Articles of Incorporation of Merger Sub, as in
effect immediately prior to the Effective Time, shall be the Articles of
Incorporation of the Surviving Corporation until thereafter amended as provided
by California Law and such Articles of Incorporation; PROVIDED, HOWEVER,
that Article I of the Articles of Incorporation of the Surviving Corporation
shall be amended to read as follows:  "FIRST: The name of the corporation is
Wavefront Technologies, Inc."

          (b)  BY-LAWS.  The By-Laws of Merger Sub, as in effect
immediately prior to the Effective Time, shall be the By-Laws of the Surviving
Corporation until thereafter amended as provided by California Law, the Articles
of Incorporation of the Surviving Corporation and such By-Laws.

          SECTION 1.05.  DIRECTORS AND OFFICERS.  The directors of Merger
Sub immediately prior to the Effective Time shall be the initial directors of
the Surviving Corporation, each to hold office in accordance with the Articles
of Incorporation and By-Laws of the Surviving Corporation, and the officers of
the Company immediately prior to the Effective Time shall be the initial
officers of the Surviving Corporation, in each case until their respective
successors are duly elected or appointed and qualified.

          SECTION 1.06.  EFFECT ON CAPITAL STOCK.  At the Effective Time, by
virtue of the Merger and without any action on the part of Parent, Merger Sub,
the Company or the holders of any of the following securities:

          (a)  CONVERSION OF SECURITIES.  Each Share issued and outstanding
immediately prior to the Effective Time (excluding any Shares to be canceled
pursuant to Section 1.06(b) and any Dissenting Shares (as defined in Section
1.09)) shall be converted, subject to Section 1.06(f), into the right to receive
0.49 shares (the "Exchange Ratio") of validly issued, fully paid and
nonassessable shares of common stock of Parent, $0.001 par value ("Parent Common
Shares").



<PAGE>
                                        4


          (b)  CANCELLATION.  Each Share held in the treasury of the
Company and each Share owned by Parent, Merger Sub or any direct or indirect
wholly owned subsidiary of the Company or Parent immediately prior to the
Effective Time shall, by virtue of the Merger and without any action on the part
of the holder thereof, cease to be outstanding, be canceled and retired without
payment of any consideration therefor and cease to exist.

          (c)  ASSUMPTION OF STOCK OPTIONS AND STOCK PURCHASE RIGHTS.  All
options to purchase Company Common Stock then outstanding under the Company's
1990 Stock Option Plan shall be assumed by Parent in accordance with
Section 5.05.  Immediately prior to the Effective Time, all rights to purchase
Company Common Stock then outstanding under the Company's Employee Stock
Purchase Plan shall be converted into shares of Company Common Stock in
accordance with Section 5.06.

          (d)  CAPITAL STOCK OF MERGER SUB.  Each share of common stock,
par value $0.001 per share, of Merger Sub issued and outstanding immediately
prior to the Effective Time shall be converted into and exchanged for one
validly issued, fully paid and nonassessable share of common stock, no par
value, of the Surviving Corporation.  Each stock certificate of Merger Sub
evidencing ownership of any such shares shall continue to evidence ownership of
such shares of capital stock of the Surviving Corporation.

          (e)  ADJUSTMENTS TO EXCHANGE RATIO.  The Exchange Ratio shall be
adjusted to reflect fully the effect of any stock split, reverse split, stock
dividend (including any dividend or distribution of securities convertible into
Parent Common Shares or Company Common Stock), reorganization, recapitalization
or other like change with respect to Parent Common Shares or Company Common
Stock occurring after the date hereof and prior to the Effective Time.

          (f)  FRACTIONAL SHARES.  No fraction of a share of Parent Common
Shares will be issued, but in lieu thereof each holder of Company Common Stock
who would otherwise be entitled to a fraction of a share of Parent Common Shares
(after aggregating all fractional shares of Parent Common Shares to be received
by such holder) shall receive from Parent an amount of cash (rounded to the
nearest whole cent), without interest, equal to the product of (i) such
fraction, multiplied by (ii) the average of the closing price for trades of
Parent Common Shares as of each of the thirty (30) consecutive trading days
immediately preceding the Effective Time as quoted in the Wall Street Journal or
other reliable financial newspaper or publication.  For the purposes of the
preceding sentence, a "trading day" means a day on which trading generally takes
place on the New York Stock Exchange (the "NYSE") and on which trading in Parent
Common Shares has occurred.

          SECTION 1.07.  EXCHANGE OF CERTIFICATES.  (a)  EXCHANGE AGENT.
Parent shall supply, or shall cause to be supplied, to or for the account of a
bank or trust company designated by Parent (the "Exchange Agent"), in trust for
the benefit of the holders of



<PAGE>
                                        5


Company Common Stock (other than Dissenting Shares), for exchange in accordance
with this Section 1.07, through the Exchange Agent, certificates evidencing the
Parent Common Shares issuable pursuant to Section 1.06 in exchange for
outstanding Shares.

          (b)  EXCHANGE PROCEDURES.  As soon as reasonably practicable
after the Effective Time, Parent will instruct the Exchange Agent to mail to
each holder of record of a certificate or certificates which immediately prior
to the Effective Time evidenced outstanding Shares (other than Dissenting
Shares) (the "Certificates") (i) a letter of transmittal (which shall specify
that delivery shall be effected, and risk of loss and title to the Certificates
shall pass, only upon proper delivery of the Certificates to the Exchange Agent
and shall be in such form and have such other provisions as Parent may
reasonably specify) and (ii) instructions to effect the surrender of the
Certificates in exchange for the certificates evidencing shares of Parent Common
Shares and, in lieu of any fractional shares thereof, cash.  Upon surrender of a
Certificate for cancellation to the Exchange Agent together with such letter of
transmittal, duly executed, and such other customary documents as may be
required pursuant to such instructions, the holder of such Certificate shall be
entitled to receive in exchange therefor (A) certificates evidencing that number
of whole Parent Common Shares which such holder has the right to receive in
accordance with the Exchange Ratio in respect of the Shares formerly evidenced
by such Certificate, (B) any dividends or other distributions to which such
holder is entitled pursuant to Section 1.07(c), and (C) cash in lieu of
fractional Parent Common Shares to which such holder is entitled pursuant to
Section 1.06(f) (the Parent Common Shares, dividends, distributions and cash
described in this clause (C) being, collectively, the "Merger Consideration"),
and the Certificate so surrendered shall forthwith be canceled.  In the event of
a transfer of ownership of Shares which is not registered in the transfer
records of the Company as of the Effective Time, Parent Common Shares and cash
may be issued and paid in accordance with this Article I to a transferee if the
Certificate evidencing such Shares is presented to the Exchange Agent,
accompanied by all documents required to evidence and effect such transfer
pursuant to this Section 1.07(b) and by evidence that any applicable stock
transfer taxes have been paid.  Until so surrendered, each outstanding
Certificate that, prior to the Effective Time, represented shares of the Company
Common Stock will be deemed from and after the Effective Time, for all corporate
purposes, other than the payment of dividends, to evidence the ownership of the
number of full shares of Parent Common Shares into which such shares of the
Company Common Stock shall have been so converted and the right to receive an
amount in cash in lieu of the issuance of any fractional shares in accordance
with Section 1.06.

          (c)  DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES.  No
dividends or other distributions declared or made after the Effective Time with
respect to Parent Common Shares with a record date after the Effective Time
shall be paid to the holder of any unsurrendered Certificate until the holder of
such Certificate shall surrender such Certificate.  Subject to applicable law,
following surrender of any such Certificate, there shall be paid to



<PAGE>
                                        6


the record holder of the certificates representing whole shares of Parent Common
Shares issued in exchange therefor, without interest, at the time of such
surrender, the amount of dividends or other distributions with a record date
after the Effective Time theretofore paid with respect to such whole shares of
Parent Common Shares.

          (d)  TRANSFERS OF OWNERSHIP.  If any certificate for shares of
Parent Common Shares is to be issued in a name other than that in which the
Certificate surrendered in exchange therefor is registered, it will be a
condition of the issuance thereof that the Certificate so surrendered will be
properly endorsed and otherwise in proper form for transfer and that the person
requesting such exchange will have paid to Parent or any person designated by it
any transfer or other taxes required by reason of the issuance of a certificate
for shares of Parent Common Shares in any name other than that of the registered
holder of the certificate surrendered, or established to the satisfaction of
Parent or any agent designated by it that such tax has been paid or is not
payable.

          (e)  NO LIABILITY.  Neither Parent, Merger Sub nor the Company
shall be liable to any holder of Company Common Stock for any Merger
Consideration (or dividends or distributions with respect thereto) delivered to
a public official pursuant to any applicable abandoned property, escheat or
similar law.

          (f)  WITHHOLDING RIGHTS.  Parent, the Surviving Corporation and
the Exchange Agent shall be entitled to deduct and withhold from the Merger
Consideration otherwise payable pursuant to this Agreement to any holder of
Company Common Stock such amounts as Parent, the Surviving Corporation or the
Exchange Agent is required to deduct and withhold with respect to the making of
such payment under the Code or any provision of state, local, provincial or
foreign tax law.  To the extent that amounts are so withheld, such withheld
amounts shall be treated for all purposes of this Agreement as having been paid
to the holder of the Shares in respect of which such deduction and withholding
was made.

          SECTION 1.08.  STOCK TRANSFER BOOKS.  At the Effective Time, the
stock transfer books of the Company shall be closed, and there shall be no
further registration of transfers of the Company Common Stock thereafter on the
records of the Company.

          SECTION 1.09.  DISSENTING SHARES.  (a)  Notwithstanding any
provision of this Agreement to the contrary, any shares of capital stock of the
Company held by a holder who has exercised dissenters' rights for such shares in
accordance with California Law and who, as of the Effective Time, has not
effectively withdrawn or lost such dissenters' rights ("Dissenting Shares"),
shall not be converted into or represent a right to receive Merger Consideration
pursuant to Section 1.06, but the holder thereof shall only be entitled to such
rights as are granted by California Law.


<PAGE>
                                        7


          (b)  Notwithstanding the provisions of subsection (a), if any
holder of Dissenting Shares shall effectively withdraw or lose (through failure
to perfect or otherwise) such holder's dissenters' rights, then, as of the later
of the Effective Time or the occurrence of such event, such holder's shares
shall automatically be converted into and represent only the right to receive
the Merger Consideration, without interest thereon, upon surrender of the
certificate or certificates representing such Dissenting Shares.

          (c)  The Company shall give Parent (i) prompt notice of any written
demands received by the Company to require the Company to purchase shares of
capital stock of the Company pursuant to Chapter 13 of California Law,
withdrawals of such demands, and any other instruments served pursuant to
California Law and received by the Company and (ii) the opportunity to
participate in all negotiations and proceedings with respect to such demands.
The Company shall not, except with the prior written consent of Parent,
voluntarily make any payment with respect to any such demands or offer to settle
or settle any such demands.

          (d)  Prior to the consummation of the Upstream Merger, the Company
shall establish an escrow account with a financial institution selected by the
Company and reasonably satisfactory to Parent and shall fund such escrow account
with cash or cash equivalents in an amount sufficient to make all payments to
holders of Dissenting Shares.  Such escrow account shall survive the Mergers.
All payments to holders of Dissenting Shares shall be made out of such escrow
account, and no such payments shall be made or otherwise funded by Parent.

          SECTION 1.10.  NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON
STOCK.  The Merger Consideration delivered upon the surrender for exchange of
Shares in accordance with the terms hereof shall be deemed to have been issued
in full satisfaction of all rights pertaining to such Shares, and there shall be
no further registration of transfers on the records of the Surviving Corporation
of Shares which were outstanding immediately prior to the Effective Time.  If,
after the Effective Time, Certificates are presented to the Surviving
Corporation for any reason, they shall be canceled and exchanged as provided in
this Article I.

          SECTION 1.11.  LOST, STOLEN OR DESTROYED CERTIFICATES.  In the
event any Certificates shall have been lost, stolen or destroyed, the Exchange
Agent shall issue in exchange for such lost, stolen or destroyed Certificates,
upon the making of an affidavit of that fact by the holder thereof, such Parent
Common Shares as may be required pursuant to Section 1.06; PROVIDED,
HOWEVER, that Parent may, in its discretion and as a condition precedent to
the issuance thereof, require the owner of such lost, stolen or destroyed
Certificates to deliver a bond in such sum as it may reasonably direct as
indemnity against any claim that may be made against Parent or the Exchange
Agent with respect to the Certificates alleged to have been lost, stolen or
destroyed.

                                        8


          SECTION 1.12.  TAX AND ACCOUNTING CONSEQUENCES.  It is intended by
the parties hereto that the Mergers shall (i) constitute a reorganization within
the meaning of Section 368 of the Code and (ii) qualify for accounting treatment
as a pooling of interests under GAAP.  The parties hereto hereby adopt this
Agreement as a "plan of reorganization" within the meaning of Sections
1.368-2(g) and 1.368-3(a) of the United States Treasury Regulations.

          SECTION 1.13.  TAKING OF NECESSARY ACTION; FURTHER ACTION.  Each
of Parent, Merger Sub and the Company in good faith will take all such
commercially reasonable and lawful action as may be necessary or appropriate in
order to effectuate the Merger in accordance with this Agreement as promptly as
possible.  If, at any time after the Effective Time, any such further action is
necessary or desirable to carry out the purposes of this Agreement and to vest
the Surviving Corporation with full right, title and possession to all assets,
property, rights, privileges, powers and franchises of the Company and Merger
Sub, the officers and directors of the Company and Merger Sub are fully
authorized in the name of their respective corporations or otherwise to take,
and will take, all such lawful and necessary action.

          SECTION 1.14.  MATERIAL ADVERSE EFFECT.  When used in connection
with the Company or any of its subsidiaries, or Parent or any of its
subsidiaries, as the case may be, the term "Material Adverse Effect" means any
change or effect that, individually or when taken together with all other such
changes or effects that have occurred prior to the date of determination of the
occurrence of the Material Adverse Effect, is or is reasonably likely to be
materially adverse to the business, assets (including intangible assets),
financial condition or results of operations of the Company and its subsidiaries
or Parent and its subsidiaries, as the case may be, in each case taken as a
whole.  For the purposes of determining whether a Material Adverse Effect has
occurred with respect to the Company under Sections 6.02(a) and 6.02(e), any
material decline in the Company's consolidated gross sales revenues after the
date hereof shall not be considered a Material Adverse Effect with respect to
the Company, if (i) such decline can most reasonably be directly attributable to
(a) a decrease in sales associated with customers delaying orders or purchases
pending completion of the Merger and the Other Merger or (b) a significant price
reduction by any major competitor of the Company, (ii) the Company has complied
with its obligations under Section 4.01 hereof and (iii) the Company has
continued to develop, market, supply and service its products in accordance with
past practice.

                                   ARTICLE II

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY


          The Company hereby represents and warrants to Parent and Merger Sub
that:

          SECTION 2.01.  ORGANIZATION AND QUALIFICATION; SUBSIDIARIES.  Each
of the Company and its subsidiaries is a corporation duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation and has the requisite corporate power and authority and is in
possession of all franchises, grants, authorizations, licenses, permits,
easements, consents, certificates, approvals and orders ("Approvals") necessary
to own, lease and operate the properties it purports to own, operate or lease
and to carry on its business as it is now being conducted, except where the
failure to be so organized, existing and in good standing or to have such power,
authority and Approvals would not have a Material Adverse Effect.  Each of the
Company and its subsidiaries is duly qualified or licensed as a foreign
corporation to do business, and is in good standing, in each jurisdiction where
the character of its properties owned, leased or operated by it or the nature of
its activities makes such qualification or licensing necessary, except for such
failures to be so duly qualified or licensed and in good standing that would not
have a Material Adverse Effect.  A true and complete list of all of the
Company's subsidiaries, together with the jurisdiction of incorporation of each
subsidiary and the percentage of each subsidiary's outstanding capital stock
owned by the Company or another subsidiary, is set forth in Section 2.01 of the
written disclosure schedule previously delivered by the Company to Parent (the
"Company Disclosure Schedule"), except as is noted therein.  Except as set forth
in Section 2.01 of the Company Disclosure Schedule, the Company does not
directly or indirectly own any equity or similar interest in, or any interest
convertible into or exchangeable or exercisable for, any equity or similar
interest in, any corporation, partnership, joint venture or other business
association or entity.

          SECTION 2.02.  ARTICLES OF INCORPORATION AND BY-LAWS.  The Company
has heretofore furnished to Parent a complete and correct copy of its Articles
of Incorporation and By-Laws, as amended to date, and, except as is set forth in
Section 2.02 of the Company Disclosure Schedule, equivalent organizational
documents of each of its subsidiaries.  Such Articles of Incorporation, By-Laws
and equivalent organizational documents of each of its subsidiaries are in full
force and effect.  Neither the Company nor any of its subsidiaries is in
violation of any of the provisions of its Articles of Incorporation or By-Laws
or equivalent organizational documents.

          SECTION 2.03.  CAPITALIZATION.  The authorized capital stock of
the Company consists of 25,000,000 shares of Company Common Stock and 5,000,000
shares of the Company's preferred stock, no par value (the "Company Preferred
Stock"), none of which



<PAGE>
                                        10


have been designated.  As of February 1, 1995, (i) 8,431,542 shares of
Company Common Stock were issued and outstanding, all of which are validly
issued, fully paid and nonassessable, (ii) no shares of Company Common Stock
were held by subsidiaries of the Company, (iii) 1,300,000 shares of Company
Common Stock were reserved for future issuance pursuant to option grants under
the Company's 1990 Stock Option Plan, (iv) 200,000 shares of Company Common
Stock were reserved for future issuance pursuant to option grants under the
Company's Employee Stock Purchase Plan, and (v) no shares of Company Preferred
Stock were issued and outstanding.  No material change in such capitalization
has occurred between February 1, 1995 and the date hereof.  Except as set forth
in this Section 2.03 or Section 2.11 hereof or in Section 2.03 or Section 2.11
of the Company Disclosure Schedule, there are no options, warrants or other
rights, agreements, arrangements or commitments of any character relating to the
issued or unissued capital stock of the Company or any of its subsidiaries or
obligating the Company or any of its subsidiaries to issue or sell any shares of
capital stock of, or other equity interests in, the Company or any of its
subsidiaries.  All shares of Company Common Stock subject to issuance as
aforesaid, upon issuance on the terms and conditions specified in the
instruments pursuant to which they are issuable, shall be duly authorized,
validly issued, fully paid and nonassessable.  There are no obligations,
contingent or otherwise, of the Company or any of its subsidiaries to
repurchase, redeem or otherwise acquire any shares of Company capital stock or
the capital stock of any subsidiary or to provide funds to or make any
investment (in the form of a loan, capital contribution or otherwise) in any
such subsidiary or any other entity other than guarantees of bank obligations of
subsidiaries entered into in the ordinary course of business.  All of the
outstanding shares of capital stock of each of the Company's subsidiaries are
duly authorized, validly issued, fully paid and nonassessable, and, other than
directors' qualifying shares, all such shares are owned by the Company or
another subsidiary free and clear of all security interests, liens, claims,
pledges, agreements, limitations in the Company's voting rights, charges or
other encumbrances of any nature whatsoever.

          SECTION 2.04.  AUTHORITY RELATIVE TO THIS AGREEMENT.  The Company
has all necessary corporate power and authority to execute and deliver this
Agreement and to perform its obligations hereunder and to consummate the
transactions contemplated hereby.  The execution and delivery of this Agreement
by the Company and the consummation by the Company of the transactions
contemplated hereby have been duly and validly authorized by all necessary
corporate action and no other corporate proceedings on the part of the Company
are necessary to authorize this Agreement or to consummate the transactions so
contemplated (other than the approval and adoption of the Merger by the holders
of at least a majority of the outstanding shares of the Company Common Stock
entitled to vote in accordance with California Law and the Company's Articles of
Incorporation and By-Laws).  The Board of Directors of the Company has
determined that it is advisable and in the best interest of the Company's
stockholders for the Company to enter into a business combination with Parent
upon the terms and subject to the conditions of this Agreement.  This Agreement
has been duly and validly executed and delivered by the Company and, assuming
the due



<PAGE>
                                        11


authorization, execution and delivery by Parent and Merger Sub, as applicable,
constitutes the legal, valid and binding obligation of the Company.

          SECTION 2.05.  NO CONFLICT; REQUIRED FILINGS AND CONSENTS.  (a)
Section 2.05(a) of the Company Disclosure Schedule includes a list of (i) all
material contracts of the Company and its subsidiaries and (ii) all agreements
which, as of the date hereof, will be required to be filed with the Securities
and Exchange Commission (the "SEC") pursuant to the requirements of the
Securities Exchange Act of 1934, as amended, and the SEC's rules thereunder
(collectively, the "Exchange Act") as "material contracts" ((i) and (ii) being,
collectively, the "Material Contracts") of the Company and its subsidiaries.

          (b)  Except as set forth in Section 2.05(b) of the Company
Disclosure Schedule, the execution and delivery of this Agreement by the Company
do not, and the performance of this Agreement by the Company will not, (i)
conflict with or violate the Articles of Incorporation or By-Laws or equivalent
organizational documents of the Company or any of its subsidiaries, (ii)
conflict with or violate any law, rule, regulation, order, judgment or decree
applicable to the Company or any of its subsidiaries or by which its or any of
their respective properties is bound or affected, or (iii) result in any breach
of or constitute a default (or an event that with notice or lapse of time or
both would become a default), or impair the Company's or any of its
subsidiaries' rights or alter the rights or obligations of any third party
under, or give to others any rights of termination, amendment, acceleration or
cancellation of, any Material Contract, or result in the creation of a lien or
encumbrance on any of the properties or assets of the Company or any of its
subsidiaries pursuant to, any note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise or other instrument or obligation
to which the Company or any of its subsidiaries is a party or by which the
Company or any of its subsidiaries or its or any of their respective properties
is bound or affected.

          (c)  The execution and delivery of this Agreement by the Company
does not, and the performance of this Agreement by the Company will not, require
any consent, approval, authorization or permit of, or filing with or

("Blue Sky Laws") and the pre-merger notification requirements of the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR

consents, approvals, authorizations or permits, or to make such filings or
notifications, would not prevent or delay consummation of the Merger, or

this Agreement, or would not otherwise have a Material Adverse Effect.

          SECTION 2.06.  COMPLIANCE; PERMITS.  (a)  Neither the Company nor
any of its subsidiaries is in conflict with, or in default or violation of, (i)
any law, rule, regulation, order, judgment or decree applicable to the Company
or any of its subsidiaries or by which its or any of their respective properties
is bound or affected or (ii) any note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise or other instrument or obligation
to which the Company or any of its subsidiaries is a party or by which the
Company or any of its subsidiaries or its or any of their respective properties
is bound or affected, except for any such conflicts, defaults or violations
which would not have a Material Adverse Effect.

          (b)  The Company and its subsidiaries hold all permits, licenses,
easements, variances, exemptions, consents, certificates, orders and approvals
from governmental authorities which are material to the operation of the
business of the Company and its subsidiaries taken as a whole (collectively, the
"Company Permits").  The Company and its subsidiaries are in compliance with the
terms of the Company Permits, except where the failure to so comply would not
have a Material Adverse Effect.

          SECTION 2.07.  SEC FILINGS; FINANCIAL STATEMENTS.  (a)  The

Company SEC Reports (i) were prepared in accordance with the requirements of the
Securities Act or the Exchange Act, as the case may be, and (ii) did not at the
time they were filed (or if amended or superseded by a filing prior to the date
of this Agreement, then on the date of such filing) contain any untrue statement
of a material fact or omit to state a material fact required to be stated
therein or necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading.  Section 2.07 of

its subsidiaries as at the respective dates thereof and the consolidated results
of its operations and cash flows for the periods indicated, except that



<PAGE>
                                        13


the unaudited interim financial statements were or are subject to normal and
recurring year-end adjustments which were not or are not expected to be material
in amount.

          (c)  The Company has heretofore furnished to Parent a complete and
correct copy of any amendments or modifications, which have not yet been filed
with the SEC but which are required to be filed, to agreements, documents or
other instruments which previously had been filed by the Company with the SEC
pursuant to the Securities Act or the Exchange Act.

          (d)  The unaudited balance sheet of the Company as of December 31,
1994 and the related unaudited consolidated income statement of the Company for
the fiscal year ended December 31, 1994 previously provided by the Company to
Parent will not deviate in any material respect from the audited balance sheet
of the Company as of December 31, 1994 and the related audited consolidated
income statement of the Company for the fiscal year ended December 31, 1994.

          SECTION 2.08.  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as

receivable other than in the ordinary course of business; or (v) any sale of a
material amount of property of the Company, except for the sale of inventory in
the ordinary course of business.

          SECTION 2.09.  NO UNDISCLOSED LIABILITIES.  Except as is disclosed
in Section 2.09 of the Company Disclosure Schedule, neither the Company nor any
of its subsidiaries has any liabilities (absolute, accrued, contingent or
otherwise) which are, in the aggregate, material to the business, operations or
financial condition of the Company and its subsidiaries taken as a whole, except
liabilities (a) adequately provided for in the Company's audited balance sheet
(including any related notes thereto) for the fiscal year ended December 31,
1993 included in the Company SEC Reports (the "1993 Balance Sheet"), (b)
incurred in the ordinary course of business and not required under GAAP to be
reflected on the Balance Sheet, or (c) incurred since December 31, 1993 in the
ordinary course of business and consistent with past practice, and liabilities
incurred in connection with this Agreement.

          SECTION 2.10.  ABSENCE OF LITIGATION.  Except as set forth in the
Company SEC Reports, there are no claims, actions, suits, proceedings or
investigations pending or, to the knowledge of the Company, threatened against
the Company or any of its subsidiaries, or

Material Adverse Effect; (iv) each Employee Plan intended to qualify under
Section 401(a) of the Code is the subject of a favorable determination letter
from the IRS, and nothing has occurred which may reasonably be expected to
impair such determination; (v) all contributions required to be made to any

<PAGE>
                                        15


meaning of Section 4043 of ERISA (excluding any such event for which the thirty
(30) day notice requirement has been waived under the regulations to Section
4043 of ERISA) nor any event described in Section 4062, 4063 or 4041 of ERISA
has occurred; and (vii) neither the Company nor any ERISA Affiliate has

regulatory agency and, in addition, (A) in the case of the Proxy
Statement/Prospectus, at the date it or any amendments or supplements thereto

                                        17



inform Parent and Merger Sub.  Notwithstanding the foregoing, the Company makes
no representation or warranty with respect to any information supplied by Parent
or Merger Sub which is contained in any of the foregoing documents.

          SECTION 2.14.  RESTRICTIONS ON BUSINESS ACTIVITIES.  Except for
this Agreement, there is no material agreement, judgment, injunction, order or
decree binding upon the Company or any of its subsidiaries which has or could
reasonably be expected to have the effect of prohibiting or impairing any
material business practice of the Company or any of its subsidiaries,
acquisition of property by the Company or any of its subsidiaries or the conduct
of business by the Company or any of its subsidiaries as currently conducted or
as proposed to be conducted by the Company.

          SECTION 2.15.  TITLE TO PROPERTY.  The Company owns no real
property.  Section 2.15(b) of the Company Disclosure Statement sets forth a true
and complete list of all real property leased by the Company or any of its
subsidiaries requiring annual lease payments of more than $50,000, and the
aggregate monthly rental or other fee payable under such lease.  The Company and
each of its subsidiaries have good, marketable and defensible title to all of
their properties and assets, free and clear of all liens, charges and
encumbrances except liens for taxes not yet due and payable and such liens or
other imperfections of title, if any, as do not materially detract from the
value of or interfere with the present use of the property affected thereby or
which would not have a Material Adverse Effect; and all leases pursuant to which
the Company or any of its subsidiaries lease from others material amounts of
real or personal property are in good standing, valid and effective in
accordance with their respective terms, and there is not under any of such
leases, any existing material default or event of default (or event which with
notice or lapse of time, or both, would constitute a material default and in
respect of which the Company or such subsidiary has not taken adequate steps to
prevent such a default from occurring) except where the lack of such good
standing, validity and effectiveness or the existence of such default or event
of default would not have a Material Adverse Effect.  All the facilities of the
Company and its subsidiaries, except such as may be under construction, are in
good operating condition and repair, except where the failure of such plants,
structures and equipment to be in such good operating condition and repair would
not, individually or in the aggregate, have a Material Adverse Effect.

          SECTION 2.16.  TAXES.  (a)  For purposes of this Agreement, "Tax"
or "Taxes" shall mean taxes, fees, levies, duties, tariffs, imposts and
governmental impositions or charges of any kind in the nature of (or similar to)
taxes, payable to any federal, state, provincial, local or foreign taxing
authority, including (without limitation) (i) income, franchise, profits, gross
receipts, AD VALOREM, net worth, value added, sales, use, service, real or

<PAGE>
                                        18


gains taxes and (ii) interest, penalties, additional taxes and additions to tax
imposed with respect thereto; and "Tax Returns" shall mean returns, reports and
information statements with respect to Taxes required to be filed with the
United States Internal Revenue Service (the "IRS") or any other taxing
authority, domestic or foreign, including, without limitation, consolidated,
combined and unitary tax returns.

          (b)  Other than as disclosed on Section 2.16(b) of the Company
Disclosure Schedule, the Company and each of its subsidiaries, and any
consolidated, combined, unitary or aggregate group for Tax purposes of which the
Company or any of its subsidiaries is or has been a member, have filed all
United States federal income Tax Returns and all other material Tax Returns
required to be filed by them or any of them, and have paid and discharged all
Taxes shown therein to be due and there are no other Taxes that would be due if
asserted by a taxing authority, except such as are being contested in good faith
by appropriate proceedings (to the extent that any such proceedings are
required) or with respect to which the Company is maintaining reserves in
accordance with GAAP in its financial statements to the extent currently
required in all material respects adequate for their payment, except, in each
instance, to the extent the failure to do so would not have a Material Adverse
Effect.  Neither the IRS nor any other taxing authority or agency is now
asserting or, to the best of the Company's knowledge, threatening to assert
against the Company or any of its subsidiaries any deficiency or claim for
additional Taxes other than additional Taxes with respect to which the Company
is maintaining reserves in accordance with GAAP in its financial statements
which are in all material respects adequate for their payment, except, in each
instance, to the extent the failure to do so would not have a Material Adverse
Effect. No Tax Return of either the Company or any of its subsidiaries is
currently being audited by any taxing authority.  No material tax claim has
become a lien on any assets of the Company or any subsidiary thereof and neither
the Company nor any of its subsidiaries has granted any waiver of any statute of
limitations with respect to, or any extension of a period for the assessment of,
any Tax.  Neither the Company nor any of its subsidiaries is required to include
in income (i) any material items in respect of any change in accounting
principles or any deferred intercompany transactions, or (ii) any installment
sale gain where, in each case, the inclusion in income would result in a tax
liability materially in excess of the reserves therefor.

          (c)  The Company on behalf of itself and all its subsidiaries
hereby represents that, other than as disclosed on Section 2.16(c) of the
Company Disclosure Schedule, and other than with respect to items the inaccuracy
of which would not have a Material Adverse Effect:  (i) neither the Company nor
any of its subsidiaries is a party to any agreement, contract or arrangement
that may result, separately or in the aggregate, in the payment of any "excess
parachute payment" within the meaning of Section 280G of the Code, determined
without regard to Section 280G(b)(4) of the Code; (ii) neither the Company nor
any of its subsidiaries has been subject to any accumulated earning tax or
personal holding company tax; neither the Company nor any of its subsidiaries
owns stock in


<PAGE>
                                        19


a passive foreign investment company within the meaning of Section 1296 of the
Code; (iv) neither the Company nor any of its subsidiaries is obligated under
any agreement with respect to industrial development bonds or other obligations
with respect to which the excludability from gross income of the holder for
United States federal or state income tax purposes could be affected by the
transactions contemplated hereunder; (v) neither the Company nor any of its
subsidiaries has entered into any deferred intercompany transaction within the
meaning of section 1.1502-13(a)(2) of the United States Treasury Regulations as
to which material items of deferred gain or loss have not been restored; and
(vi) no material excess loss account within the meaning of section
1.1502-31T(a)(2)(v) of the United States Treasury Regulations exists with
respect to the stock of any of the Company's subsidiaries.

          (d)  No power of attorney has been granted by the Company or any of
its subsidiaries with respect to any matter relating to Taxes which is currently
in force.

          (e)  Except as set forth in Section 2.16(e) of the Company
Disclosure Schedule, neither the Company nor any of its subsidiaries is a party
to any agreement or arrangement (written or oral) providing for the allocation
or sharing of Taxes.

          (f)  The Company and each of its subsidiaries have withheld from
each payment made to any of their respective past or present employees, officers
or directors the amount of all Taxes and other deductions required to be
withheld therefrom and paid the same to the proper tax or other receiving
officers within the time required by law, except to the extent that any failure
to do so would not have a Material Adverse Effect.

          (g)  Except as set forth in Section 2.16(g) of the Company
Disclosure Schedule, the Company has remitted to the appropriate Tax authority
when required by law to do so all amounts collected by it on account of all
retail sales Tax.

          (h)  Except as disclosed in Section 2.16(b) of the Company
Disclosure Schedule, there has been no material debt to a third party of the
Company or any of its subsidiaries which has been forgiven and which has given
rise to (or is expected to give rise to) "cancellation of indebtedness income"
under the provisions of the Code.

          SECTION 2.17.  ENVIRONMENTAL MATTERS.  Except in all cases, in the
aggregate, as have not had and could not reasonably be expected to have a
Material Adverse Effect, the Company and each of its subsidiaries to the best of
the Company's knowledge (i) have obtained all applicable permits, licenses and
other authorizations which are required under federal, state, provincial or
local laws relating to pollution or protection of the environment, including
laws relating to emissions, discharges, releases or threatened releases of

decree, judgment, notice or demand letter issued, entered, promulgated or
approved thereunder; (iii) as of the date hereof, are not aware of nor have
received notice of any event, condition, circumstance, activity, practice,
incident, action or plan which is reasonably likely to interfere with or prevent
continued compliance with or which would give rise to any common law or
statutory liability, or otherwise form the basis of any claim, action, suit or
proceeding, based on or resulting from the Company's or any of its subsidiary's
(or any of their respective agent's) manufacture, processing, distribution, use,
treatment, storage, disposal, transport or handling, or the emission, discharge
or release into the environment, of any pollutant, contaminant or hazardous or
toxic material or waste; and (iv) have taken all actions necessary under
applicable requirements of federal, state or local laws, rules or regulations to

(other than Volpe, Welty & Company) is entitled to any brokerage, finder's or
other fee or commission in connection with the transactions contemplated by this
Agreement based upon arrangements made by or on behalf of the Company.  The
Company has heretofore furnished to Parent a complete and correct copy of all

firm would be entitled to any payment relating to the transactions contemplated
hereunder.

          SECTION 2.19.  FULL DISCLOSURE.  No statement contained in any
certificate or schedule furnished or to be furnished by the Company or its
subsidiaries to Parent or Merger Sub in, or pursuant to the provisions of, this
Agreement contains or shall contain any untrue statement of a material fact or

circumstances under which it was made, to make the statements herein or therein
not misleading.

          SECTION 2.20.  INTELLECTUAL PROPERTY.  (a)  The Company owns, or
is licensed or otherwise possesses legally sufficient rights to use, all
patents, trademarks, trade names, service marks, copyrights and any applications
therefor, technology, know-how, computer software programs or applications (in
both source code and object code form) and tangible or intangible proprietary

subject matter thereof, the applicable royalty and the term thereof.

          (b)  Except as set forth in Section 2.20(b) of the Company

the Company Intellectual Property Rights, any trade secret material to the
Company, or Third Party Intellectual Property Rights to the extent arising out
of any use, reproduction or distribution of such Third Party Intellectual
Property Rights by or through the Company, are currently pending or, to the
knowledge of the Company, are threatened by any person, nor does the Company
know of any valid grounds for any bona fide claims (i) to the effect that the
manufacture, sale, licensing or use of any product as now used, sold or licensed
or proposed for use, sale or license by the Company infringes on any copyright,
patent, trademark, service mark or trade secret; (ii) against the use by the
Company of any trademarks, trade names, trade secrets, copyrights, patents,

the Company Intellectual Property Rights or other trade secret material to the
Company; or (iv) challenging the Company's license or



<PAGE>
                                        22


legally enforceable right to use of the Third Party Intellectual Rights.  To the
Company's knowledge, after reasonable investigation, all patents, registered
trademarks, maskworks and copyrights held by the Company are valid and
subsisting.  Except as set forth in Section 2.20(b) of the Company Disclosure
Schedule, to the Company's knowledge, there is no material unauthorized use,
infringement or misappropriation of any of the Company Intellectual Property by
any third party, including any employee or former employee of the Company or any
of its subsidiaries.  Except as set forth in Section 2.20(b) of the Company
Disclosure Schedule, neither the Company nor any of its subsidiaries (i) has
been sued or charged in writing as a defendant in any claim, suit, action or
proceeding which involves a claim or infringement of trade secrets, any patents,
trademarks, service marks, maskworks or copyrights and which has not been
finally terminated prior to the date hereof or been informed or notified by any
third party that the Company may be engaged in such infringement or (ii) has
knowledge of any infringement liability with respect to, or infringement by, the
Company or any of its subsidiaries of any trade secret, patent, trademark,
service mark, maskwork or copyright of another.

          (c)  Each employee of the Company has executed a confidentiality

Reports, since December 5, 1994, no event has occurred that would be required to
be reported as a Certain Relationship or Related Transaction, pursuant to Item
404 of Regulation S-K promulgated by the SEC.

          SECTION 2.22.  INSURANCE.  Section 2.22 of the Company Disclosure
Schedule lists all material insurance policies and fidelity bonds covering the
assets, business, equipment, properties, operations, employees, officers and
directors of the Company and its subsidiaries.  There is no claim by the Company
or any of its subsidiaries pending under any of such policies or bonds as to
which coverage has been questioned, denied or disputed by the underwriters of
such policies or bonds.  All premiums payable under all such policies and bonds
have been paid and the Company and its subsidiaries are otherwise in full
compliance with the terms of such policies and bonds (or other policies and
bonds providing substantially similar insurance coverage).  Such policies of
insurance and bonds are of the type and in amounts customarily carried by
persons conducting businesses similar to those of the Company and its
subsidiaries.  The Company does not know of any threatened termination of, or
material premium increase with respect to, any of such policies.

          SECTION 2.23.  OPTION PLANS.  Except as set forth in Section
2.23 of the Company Disclosure Schedule, the Board of Directors of the Company
has taken all necessary action (or refrained from taking action, where
appropriate) under the Company Stock Option Plan (as defined in Section 5.05) so
that no Stock Options (or any portion


<PAGE>
                                        23



thereof) will be accelerated or entitled to receive cash or other property as

the only vote of the holders of any class or series of the Company's capital
stock necessary to approve the Merger.

          SECTION 2.25.  POOLING MATTERS.  Neither the Company nor any of
its affiliates, to the Company's knowledge and based upon consultation with its
independent accountants, is aware of any facts or has taken or agreed to take
any action that (without giving effect to any action taken or agreed to be taken
by Parent or any of its affiliates) would affect the ability of Parent to
account for the business combination to be effected by the Mergers as a pooling
of interests.

          SECTION 2.26.  OPINION OF FINANCIAL ADVISOR.  The Company has been
advised by its financial advisor, Volpe, Welty & Company, that in its opinion,
as of the date hereof, the terms of the Merger are fair to the stockholders of
the Company from a financial point of view, and has delivered a written copy of
such opinion to Parent.

                                   ARTICLE III

             REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB

          Parent and Merger Sub hereby, jointly and severally, represent and
warrant to the Company that:

          SECTION 3.01.  ORGANIZATION AND QUALIFICATION.    Parent and each
of its subsidiaries is a corporation duly organized, validly existing and in
good standing under the laws of the jurisdiction of its incorporation and has
the requisite corporate power and authority and is in possession of all
Approvals necessary to own, lease and operate the properties it purports to own,
operate or lease and to carry on its business as it is now being conducted,
except where the failure to be so organized, existing and in good standing or to
have such power, authority and Approvals would not have a Material Adverse
Effect.  Parent and each of its subsidiaries is duly qualified or licensed as a
foreign corporation to do business, and is in good standing, in each
jurisdiction where the character of its properties owned, leased or operated by
it or the nature of its activities makes such qualification or licensing
necessary, except for such failures to be so duly qualified or licensed and in
good standing that would not have a Material Adverse Effect.


<PAGE>
                                        24


          SECTION 3.02.  AUTHORITY RELATIVE TO THIS AGREEMENT.  Each of
Parent and Merger Sub has all necessary corporate power and authority to execute
and deliver this Agreement and to perform its obligations hereunder and to
consummate the transactions contemplated hereby.  The execution and delivery of
this Agreement by Parent and Merger Sub and the consummation by Parent and
Merger Sub of the transactions contemplated hereby have been duly and validly
authorized by all necessary corporate action on the part of Parent and Merger
Sub, and no other corporate proceedings on the part of Parent or Merger Sub are
necessary to authorize this Agreement or to consummate the transactions so
contemplated.  The Board of Directors of Parent has determined that it is
advisable and in the best interest of Parent's stockholders for Parent to enter
into a business combination with the Company upon the terms and subject to the
conditions of this Agreement.  This Agreement has been duly and validly executed
and delivered by Parent and Merger Sub and, assuming the due authorization,
execution and delivery by the Company, constitutes a legal, valid and binding
obligation of Parent and Merger Sub.

          SECTION 3.03.  NO CONFLICT; REQUIRED FILINGS AND CONSENTS.  (a)
Section 3.03(a) of the written disclosure schedule previously delivered by
Parent and Merger Sub to the Company (the "Parent Disclosure Schedule") includes
a list of all Material Contracts of Parent and its subsidiaries.

          (b)  Except as set forth in Section 3.03(b) of the Parent
Disclosure Schedule, the execution and delivery of this Agreement by Parent and
Merger Sub do not, and the performance of this Agreement by Parent and Merger
Sub shall not, (i) conflict with or violate the Certificate of Incorporation or
By-Laws of Parent or the Articles of Incorporation or By-Laws of Merger Sub,
(ii) conflict with or violate any law, rule, regulation, order, judgment or
decree applicable to Parent or any of it subsidiaries or by which its or their
respective properties are bound or affected, or (iii) result in any breach of or
constitute a default (or an event which with notice or lapse of time or both
would become a default) under, or impair Parent's rights or alter the rights or
obligations of any third party under, or give to others any rights of
termination, amendment, acceleration or cancellation of, any Material Contract
or result in the creation of a lien or encumbrance on any of the properties or
assets of Parent or any of it subsidiaries pursuant to, any material note, bond,
mortgage, indenture, contract, agreement, lease, license, permit, franchise or
other instrument or obligation to which Parent or any of its subsidiaries is a
party or by which Parent or any of its subsidiaries or its or any of their
respective properties are bound or affected, except in any such case for any
such breaches, defaults or other occurrences that would not have a Material
Adverse Effect.

          (c)  The execution and delivery of this Agreement by Parent and
Merger Sub will not require any consent, approval, authorization or permit of,
or filing with or notification to, any governmental or regulatory authority,
domestic or foreign, except (i) for applicable requirements, if any, of the
Securities Act, the Exchange Act, the Blue Sky Laws



<PAGE>
                                        25


and the pre-merger notification requirements of the HSR Act and (ii) where the
failure to obtain such consents, approvals, authorizations or permits, or to
make such filings or notifications, would not prevent or delay consummation of
the Merger, or otherwise prevent Parent or Merger Sub from performing their
respective obligations under this Agreement, and would not have a Material
Adverse Effect.

          SECTION 3.04.  CERTIFICATE OF INCORPORATION AND BY-LAWS.  Parent
has heretofore furnished to the Company a complete and correct copy of its
Certificate of Incorporation and the By-Laws, as amended to date.  Such
Certificate of Incorporation and By-Laws are in full force and effect.  Neither
Parent nor Merger Sub is in violation of any of the provisions of its
Certificate of Incorporation or By-Laws.

          SECTION 3.05.  CAPITALIZATION.  As of January 31, 1995, the
authorized capital stock of Parent consisted of (i) 500,000,000 shares of Parent
Common Shares of which:  143,485,318 shares were issued and outstanding, no

purchase 2,230,600 shares of Parent Common Shares, no material change in such
capitalization has occurred between January 31, 1995 and the date hereof.  The
authorized capital stock of Merger Sub consists of 1,000 shares of common stock,
par value $0.001 per share, 100 shares of which, as of the date hereof, are
issued and outstanding.  All of the outstanding shares of Parent's and Merger
Sub's respective capital stock have been duly authorized and validly existing
and are fully paid and nonassessable.  Parent owns all of the capital stock of
Merger Sub.

          SECTION 3.06.  COMPLIANCE; PERMITS.  (a)  Neither Parent nor any
of its subsidiaries is in conflict with, in default with respect to or in
violation of (i) any law, rule, regulation, order, judgment or decree applicable
to Parent or any of its subsidiaries or by which its or any of their respective
properties is bound or affected or (ii) any note, bond, mortgage, indenture,
contract, agreement, lease, license, permit, franchise or other instrument or
obligation to which Parent or any of its subsidiaries is a party or by which

would not have a Material Adverse Effect.


<PAGE>
                                        26


          (b)  Parent and its subsidiaries hold all permits, licenses,
easements, variances, exemptions, consents, certificates, orders and approvals
from governmental authorities which are material to the operation of the
business of the Company and its subsidiaries taken as a whole as it is now being
conducted (collectively, the "Parent Permits").  Parent and its subsidiaries are
in compliance with the terms of the Parent Permits, except where the failure to
so comply would not have a Material Adverse Effect.

          SECTION 3.07.  SEC FILINGS; FINANCIAL STATEMENTS.  (a)  Parent has
filed all forms, reports and documents required to be filed with the SEC since
June 30, 1992, and has heretofore delivered to the Company, in the form filed
with the SEC, (i) its Annual Reports on Form 10-K for the fiscal years ended

fiscal quarter ended September 30, 1994, (ii) all proxy statements relating to
Parent's meetings of stockholders (whether annual or special) held since June

on Form 10-Q and Reports on Form 3, 4 or 5 filed on behalf of affiliates of the
Parent) filed by Parent with the SEC since June 30, 1992 and (iv) all amendments
and supplements to all such reports and registration statements filed by Parent
with the SEC (collectively, the "Parent SEC Reports").  The Parent SEC Reports
(i) were prepared in accordance with the requirements of the Securities Act or
the Exchange Act, as the case may be, and (ii) did not at the time they were
filed (or if amended or superseded by a filing prior to the date of this
Agreement, then on the date of such filing) contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.  None of Parent's
subsidiaries is required to file any forms, reports or other documents with the
SEC.

          (b)  Each of the consolidated financial statements (including, in
each case, any related notes thereto) contained in the Parent SEC Reports has
been prepared in accordance with GAAP applied on a consistent basis throughout
the periods involved (except as may be indicated in the notes thereto) and each
fairly presents the consolidated financial position of Parent and its
subsidiaries as at the respective dates thereof and the consolidated results of
its operations and cash flows for the periods indicated, except that the
unaudited interim financial statements were or are subject to normal and
recurring year-end adjustments which were not or are not expected to be material
in amount.

          (c)  Parent has heretofore furnished to the Company a complete and
correct copy of any amendments or modifications, which have not yet been filed
with the SEC but which are required to be filed, to agreements, documents or

<PAGE>
                                        27


          SECTION 3.08.  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as
set forth in Section 3.08 of the Parent Disclosure Schedule, since June 30,
1994, Parent has conducted its business in the ordinary course and there has not
occurred:  (i) any Material Adverse Effect; (ii) any amendments or changes in
the Certificate of Incorporation or By-Laws of Parent; (iii) any damage to,
destruction or loss of any assets of the Parent (whether or not covered by
insurance) that could have a Material Adverse Effect; (iv) any revaluation by
Parent of any of its assets, including, without limitation, writing down the
value of capitalized software or inventory or writing off notes or accounts
receivable other than in the ordinary course of business; or (v) except as
disclosed in Section 3.08 of the Parent Disclosure Schedule, any other action or
event that would have required the consent of the Company pursuant to Section
4.03 had such action or event occurred after the date of this Agreement.

          SECTION 3.09.  RESTRICTIONS ON BUSINESS ACTIVITIES.  Except for
this Agreement, there is no material agreement, judgment, injunction, order or
decree binding upon Parent or any of its subsidiaries which has or could
reasonably be expected to have the effect of prohibiting or materially impairing
any business practice of Parent or any of its subsidiaries, any acquisition of
property by Parent or any of its subsidiaries or the conduct of business by
Parent or any of its subsidiaries as currently conducted or as proposed to be
conducted by Parent.

          SECTION 3.10.  TITLE TO PROPERTY.  Parent and each of its
subsidiaries have good, marketable and defensible title to all of their
properties and assets, free and clear of all liens, charges and encumbrances
except liens for taxes not yet due and payable and such liens or other
imperfections of title, if any, as do not materially detract from the value of
or interfere with the present use of the property affected thereby or which
would not have a Material Adverse Effect; and, to Parent's knowledge, all leases
pursuant to which Parent or any of its subsidiaries lease from others material
amounts of real or personal property are in good standing, valid and effective
in accordance with their respective terms, and there is not, to the knowledge of
Parent, under any of such leases, any existing material default or event of
default (or event which, with notice or lapse of time, or both, would constitute
a material default and in respect of which Parent or such subsidiary has not
taken adequate steps to prevent such a default from occurring) except where the
lack of such good standing, validity and effectiveness, or the existence of such
default or event of default would not have a Material Adverse Effect.

          SECTION 3.11.  FULL DISCLOSURE.  No statement contained in any
certificate or schedule furnished or to be furnished by Parent or Merger Sub to
the Company in, or pursuant to the provisions of, this Agreement contains or
will contain any untrue statement of a material fact or omits or shall omit to
state any material fact necessary, in the light of the circumstances under which
it was made, to make the statements herein or therein not misleading.


<PAGE>
                                        28




          SECTION 3.12.  NO UNDISCLOSED LIABILITIES.  (a)  Except as is
disclosed in Section 3.12 of the Parent Disclosure Schedule or the Parent SEC
Reports, neither Parent nor any of its subsidiaries has any liabilities
(absolute, accrued, contingent or otherwise) which are, in the aggregate,
material to the business, operations or financial condition of Parent and its
subsidiaries taken as a whole, except liabilities (i) adequately provided for in
Parent's balance sheet (including any related notes thereto) as of June 30, 1994
included in the Parent SEC Reports (the "June 30 Balance Sheet"), (ii) incurred
in the ordinary course of business and not required under GAAP to be reflected
on the June 30 Balance Sheet, or (iii) incurred since June 30, 1994 in the
ordinary course of business and consistent with past practice, and liabilities
incurred in connection with this Agreement.

          (b)  As of the date hereof and the Effective Time, except for
obligations or liabilities incurred in connection with its incorporation or
organization and the transactions contemplated by this Agreement and except for
this Agreement and any other agreements or arrangements contemplated by this
Agreement, Merger Sub has not and will not have incurred, directly or
indirectly, through any subsidiary or affiliate, any obligations or liabilities
or engaged in any business activities of any type or kind whatsoever or entered
into any agreements or arrangements with any person.

          SECTION 3.13.  ABSENCE OF LITIGATION.  Except as set forth in
Section 3.13 of the Parent Disclosure Schedule or as reflected in the Parent SEC
Reports, there are no claims, actions, suits, proceedings or investigations
pending or, to the knowledge of Parent, threatened against Parent or any of its
subsidiaries, or any properties or rights of Parent or any of its subsidiaries,
before any court, arbitrator or administrative, governmental or regulatory
authority or body, domestic or foreign, that could have a Material Adverse
Effect.

          SECTION 3.14.  INSURANCE.  Parent and its subsidiaries maintain
fire and casualty, general liability, business interruption, product liability
and sprinkler and water damage insurance that Parent believes to be reasonably
prudent for its business.

          SECTION 3.15.  REGISTRATION STATEMENT; PROXY STATEMENT/PROSPECTUS.
Subject to the accuracy of the representations of the Company in Section 2.13,
the Registration Statement pursuant to which the Parent Common Shares to be
issued in the Merger will be registered with the SEC shall not, at the time the
Registration Statement (including any amendments or supplements thereto) is
declared effective by the SEC, contain any untrue statement of a material fact
or omit to state any material fact necessary in order to make the statements
included therein, in light of the circumstances under which they were made, not
misleading.  Subject to the accuracy of the representations of the Company in
Section 2.13, the information supplied by Parent for inclusion in the Proxy
Statement/Prospectus will not, on the date the Proxy Statement/Prospectus is
first mailed to stockholders, at the time of the Company Stockholders' Meeting
and at the Effective Time, contain any statement which, at such time and in
light of the circumstances under which it shall be made, is false or



<PAGE>
                                        29


misleading with respect to any material fact, or will omit to state any material
fact necessary in order to make the statements therein not false or misleading.
If at any time prior to the Effective Time any event relating to Parent, Merger
Sub or any of their respective affiliates, officers or directors should be
discovered by Parent or Merger Sub which should be set forth in an amendment to
the Registration Statement or a supplement to the Proxy Statement/ Prospectus,
Parent or Merger Sub will promptly inform the Company.  Notwithstanding the
foregoing, Parent makes no representation or warranty with respect to any
information supplied by the Company which is contained in, or furnished in
connection with the preparation of, any of the foregoing.

          SECTION 3.16.  TAXES.  Other than as disclosed on Section 3.16 of
the Parent Disclosure Schedule, Parent and each of its subsidiaries, and any
consolidated, combined, unitary or aggregate group for Tax purposes of which
Parent or any of its subsidiaries is or has been a member, have filed all United
States federal income Tax Returns and all other material Tax Returns required to
be filed by them or any of them, and have paid and discharged all Taxes shown
therein to be due and there are no other Taxes that would be due if asserted by
a taxing authority, except such as are being contested in good faith by
appropriate proceedings (to the extent that any such proceedings are required)
or with respect to which Parent is maintaining reserves in accordance with GAAP
in its financial statements to the extent currently required in all material
respects adequate for their payment, except, in each instance, to the extent the
failure to do so would not have a Material Adverse Effect.  Neither the IRS nor
any other taxing authority or agency is now asserting or, to the best of
Parent's knowledge, threatening to assert against Parent or any of its
subsidiaries any deficiency or claim for additional Taxes other than additional
Taxes with respect to which Parent is maintaining reserves in accordance with
GAAP in its financial statements which are in all material respects adequate for
their payment, except, in each instance, to the extent that the failure to do so
would not have a Material Adverse Effect.   Except as set forth in Section 3.16
of the Parent Disclosure Schedule, no Tax Return of either Parent or any of its
subsidiaries is currently being audited by any taxing authority except as would
not have a Material Adverse Effect.  Except as set forth in Section 3.16 of the
Parent Disclosure Schedule, no material tax claim has become a lien on any
assets of Parent or any subsidiary thereof and neither Parent nor any of its
subsidiaries has, except as would not have a Material Adverse Effect, granted
any waiver of any statute of limitations with respect to, or any extension of a
period for the assessment of, any Tax.

          SECTION 3.17.  BROKERS.  No broker, finder or investment banker
(other than Morgan Stanley & Co. Incorporated and Unterberg Harris L.P.) is
entitled to any brokerage, finder's or other fee or commission in connection
with the transactions contemplated by this Agreement based upon arrangements
made by or on behalf of Parent or Merger Sub.

          SECTION 3.18.  OPINION OF FINANCIAL ADVISOR.  Parent has been
advised by its financial advisor, Morgan Stanley & Co. Incorporated, that in its
opinion, as of the date


<PAGE>
                                        30


hereof, the Exchange Ratio is fair from a financial point of view to Parent, and
has delivered a copy of such opinion to the Company.

          SECTION 3.19.  POOLING MATTERS.  Neither Parent nor any of its
affiliates, to its knowledge and based upon consultation with its independent
accountants, is aware of any fact or has taken or agreed to take any action that
(without giving effect to any action taken or agreed to be taken by the Company
or any of its affiliates) would affect the ability of Parent to account for the
business combination to be effected by the Mergers as a pooling of interests.

          SECTION 3.20.  NO STOCKHOLDER VOTE.  No vote of the stockholders
of Parent is necessary to approve the Merger or the issuance of Parent Common
Shares therein.


                                   ARTICLE IV

                     CONDUCT OF BUSINESS PENDING THE MERGER

          SECTION 4.01.  CONDUCT OF BUSINESS BY THE COMPANY PENDING THE
MERGER.  During the period from the date of this Agreement and continuing until
the earlier of the termination of this Agreement or the Effective Time, the
Company covenants and agrees that, unless Parent shall otherwise agree in
writing, the Company shall conduct its business and shall cause the businesses
of its subsidiaries to be conducted only in, and the Company and its
subsidiaries shall not take any action except in, the ordinary course of
business and in a manner consistent with past practice; and the Company shall
use reasonable commercial efforts to preserve substantially intact the business
organization of the Company and its subsidiaries, to keep available the services
of the present officers, employees and consultants of the Company and its
subsidiaries, to take all reasonable action in the ordinary course of business
and in a manner consistent with past practice necessary to prevent the loss,
cancellation, abandonment, forfeiture or expiration of any Company Intellectual
Property, and to preserve the present relationships of the Company and its
subsidiaries with customers, suppliers and other persons with which the Company
or any of its subsidiaries has significant business relations.  By way of
amplification and not limitation, except as contemplated by this Agreement,
neither the Company nor any of its subsidiaries shall, during the period from
the date of this Agreement and continuing until the earlier of the termination
of this Agreement or the Effective Time, directly or indirectly do, or propose
to do, any of the following without the prior written consent of Parent:

          (a)  amend or otherwise change the Company's Articles of
     Incorporation or By-Laws;


<PAGE>
                                        31


               (b)  issue, sell, pledge, dispose of or encumber, or authorize
     the issuance, sale, pledge, disposition or encumbrance of, any shares of
     capital stock of any class, or any options, warrants, convertible
     securities or other rights of any kind to acquire any shares of capital
     stock, or any other ownership interest (including, without limitation, any
     phantom interest) of the Company, any of its subsidiaries or affiliates
     (except for the issuance of shares of the Company Common Stock issuable
     pursuant to employee stock options under the Company Stock Option Plans (as
     defined in Section 5.05) or pursuant to rights to purchase such shares
     under the Company Stock Purchase Plan (as defined in Section 5.06), which
     options or rights, as the case may be, are outstanding on the date hereof);

          (c)  sell, pledge, dispose of or encumber any assets of the Company
     or any of its subsidiaries (except for (i) sales of assets in the ordinary

               (n)  take, or agree in writing or otherwise to take, any of the
     actions described in Sections 4.01(a) through (m) above, or any action
     which would make any of the representations or warranties of the Company

     performing or cause the Company not to perform its covenants hereunder or
     result in any of the conditions to the Merger set forth herein not being
     satisfied.

          SECTION 4.02.  NO SOLICITATION.  (a)  The Company shall not,
directly or indirectly, through any officer, director, employee, representative
or agent of the Company or any of its subsidiaries, solicit or encourage
(including by way of furnishing information) the initiation of any inquiries or
proposals regarding any merger, amalgamation, take-over bid, sale of substantial
assets, sale of shares of capital stock (including without limitation by way of
a tender offer) or similar transactions involving the Company or any
subsidiaries of the Company (any of the foregoing inquiries or proposals being
referred to herein as an "Acquisition Proposal"); PROVIDED, HOWEVER, that
nothing contained in this Agreement shall prevent the Board of Directors of the
Company from referring any third party to this Section 4.02(a).  Nothing
contained in this Section 4.02(a) or any other provision of this Agreement shall
prevent the Board of Directors of the Company from considering, negotiating,
approving and recommending to the stockholders of the Company an unsolicited
bona fide written Acquisition Proposal which the Board of Directors of the
Company determines in good faith (after consultation with its financial
advisors, and after receiving a written opinion of outside counsel, or the
advice of outside counsel that is reflected in the minutes of the Board of
Directors of the Company, to the effect that the Board of Directors is required
to do so in order to discharge properly its fiduciary duties) would result in a
transaction more favorable to the Company's stockholders than the transaction
contemplated by this Agreement (any such Acquisition Proposal being referred to
herein as a "Superior Proposal").

          (b)  The Company shall immediately notify Parent after receipt of
any Acquisition Proposal or any request for nonpublic information relating to
the Company or any of its subsidiaries in connection with an Acquisition
Proposal or for access to the properties, books or records of the Company or any
subsidiary by any person or entity that informs the Board of Directors of the
Company or such subsidiary that it is considering making, or has made, an
Acquisition Proposal.  Such notice to Parent shall be made orally and in writing
and shall indicate in reasonable detail the identity of the offeror and the
terms and conditions of such proposal, inquiry or contact.

          (c)  If the Board of Directors of the Company receives a request
for material nonpublic information by a party who makes a bone fide Acquisition
Proposal and the Board of Directors of the Company determines that such
proposal, if consummated pursuant to its terms, would be a Superior Proposal,
then, and only in such case, the Company may, subject to the execution of a
confidentiality and standstill agreement



<PAGE>
                                        34


substantially similar to that then in effect between the Company and Parent,
provide such party with access to information regarding the Company.

          (d)  The Company shall immediately cease and cause to be terminated
any existing discussions or negotiations with any parties (other than Parent and
Merger Sub) conducted heretofore with respect to any of the foregoing.  The
Company agrees not to release any third party from any confidentiality or
standstill agreement to which the Company is a party.

          (e)  The Company shall ensure that the officers, directors and
employees of the Company and its subsidiaries and any investment banker or other
advisor or representative retained by the Company are aware of the restrictions
described in this Section, and shall be responsible for any breach of this
Section 4.02 by such bankers, advisors and representatives.

          SECTION 4.03.  CONDUCT OF BUSINESS BY PARENT PENDING THE MERGER.
During the period from the date of this Agreement and continuing until the
earlier of the termination of this Agreement or the Effective Time, Parent
covenants and agrees that, unless the Company shall otherwise agree in writing,
Parent shall conduct its business, and cause the businesses of its subsidiaries
to be conducted, in the ordinary course of business and consistent with past
practice, other than actions taken by Parent or its subsidiaries in
contemplation of the Merger and the Other Merger, and shall not directly or
indirectly do, or propose to do, any of the following without the prior written
consent of the Company:

          (a)  amend or otherwise change Parent's Articles of Incorporation, or
     amend the terms of the Parent Common Shares, except for the filing of the
     certificate of designation referred to in the Other Merger Agreement;

          (b)  except for the Other Merger, acquire or agree to acquire, by
     merging or consolidating with, by purchasing an equity interest in or a
     portion of the assets of, or by any other manner, any business or any
     corporation, partnership, association or other business organization or
     division thereof, or otherwise acquire or agree to acquire any assets of
     any other person, which, in each case, would materially delay or prevent
     the consummation of the transactions contemplated by this Agreement;

          (c)  declare, set aside, make or pay any dividend or other
     distribution (whether in cash, stock or property or any combination
     thereof) in respect of any of its capital stock, except that a wholly owned
     subsidiary of Parent may declare and pay a dividend to its parent;

          (d)  sell, transfer, license, sublicense or otherwise dispose of
     any material assets; or


<PAGE>
                                        35


          (e)  take or agree in writing or otherwise to take any action which
     would make any of the representations or warranties of Parent contained in
     this Agreement untrue or incorrect or prevent Parent from performing or
     cause Parent not to perform its covenants hereunder.


                                    ARTICLE V

                              ADDITIONAL AGREEMENTS

          SECTION 5.01.  PROXY STATEMENT/PROSPECTUS; REGISTRATION STATEMENT.

and Parent shall prepare and file with the SEC preliminary proxy materials which
shall constitute the Proxy Statement of the Company and the Registration
Statement of Parent with respect to the Parent Common Shares to be issued in
connection with the Merger.  As promptly as practicable after comments are
received from the SEC thereon and after the furnishing by the Company and Parent
of all information required to be contained therein, the Company and Parent
shall file with the SEC a combined proxy and registration statement on Form S-4
(or on such other form as shall be appropriate) relating to the approval of the
Merger and the transactions contemplated hereby by the stockholders of the
Company and shall use all reasonable efforts to cause the Registration Statement
to become effective as soon thereafter as practicable.  The Proxy Statement
shall include the recommendation of the Board of Directors of the Company in
favor of the Merger, subject to the second sentence of Section 4.02.

          SECTION 5.02.  STOCKHOLDERS' MEETING.  The Company shall in
accordance with California Law and the Company's Articles of Incorporation and
Bylaws call and hold the Company Stockholders' Meeting as promptly as
practicable for the purpose of voting upon the approval of the Merger.  The
Company shall use its reasonable best efforts to hold the Company Stockholders'
Meeting as soon as practicable after the date on which the Registration
Statement becomes effective or, if requested by Parent, the date on which the
Other Merger is consummated provided the Other Merger is consummated after the
effective date of the Registration Statement.  The Company shall use its
reasonable best efforts to solicit from their respective stockholders proxies in
favor of the approval of the Merger, and shall take all other action necessary
or advisable to secure the vote or consent of stockholders required by
California Law to obtain such approvals.

          SECTION 5.03.  ACCESS TO INFORMATION; CONFIDENTIALITY.  (a)
Upon reasonable notice and subject to restrictions contained in confidentiality
agreements to which such party is subject, the Company and Parent shall each
(and shall cause each of their subsidiaries to) afford to the officers,
employees, accountants, counsel and other representatives of the other,
reasonable access, during the period prior to the Effective Time, to all its
properties, books, contracts, commitments and records and, during such period,
the


<PAGE>
                                        36


Company and Parent each shall (and shall cause each of their subsidiaries to)
furnish promptly to the other all information concerning its business,
properties and personnel as such other party may reasonably request, and each
shall make available to the other the appropriate individuals (including
attorneys, accountants and other professionals) for discussion of the other's
business, properties and personnel as either party may reasonably request.  Each
party shall keep such information confidential in accordance with the terms of
the currently effective confidentiality agreement (the "Confidentiality
Agreement") between Parent and the Company.

          (b)  The Company shall provide to Parent promptly as available
drafts and printers' proofs of the Company's Annual Report on Form 10-K for the
fiscal year ended December 31, 1994 and the Company's proxy statement related to
its 1995 annual meeting of shareholders, and Parent shall provide to the
Company, promptly as available, drafts and printers' proofs of Parent's Form
10-Q for the quarter ended December 31, 1994.

          SECTION 5.04.  CONSENTS; APPROVALS.  The Company and Parent shall
each use their best efforts to obtain all consents, waivers, approvals,
authorizations or orders (including, without limitation, all United States and
foreign governmental and regulatory rulings and approvals), and the Company and
Parent shall make all filings (including, without limitation, all filings with
United States and foreign governmental or regulatory agencies) required in
connection with the authorization, execution and delivery of this Agreement by
the Company and Parent and the consummation by them of the transactions
contemplated hereby.  The Company and Parent shall furnish all information
required to be included in the Proxy Statement and the Registration Statement,
or for any application or other filing to be made pursuant to the rules and
regulations of any United States, Canadian or foreign governmental body in
connection with the transactions contemplated by this Agreement.

          SECTION 5.05.  STOCK OPTIONS.  (a)  At the Effective Time, the
Company's obligations with respect to each outstanding option to purchase shares
of Company Common Stock (each, a "Company Option") under the Company's 1990
Stock Option Plan (the "Company Stock Option Plan"), whether vested or unvested,
will be assumed by Parent.  Each Company Option so assumed by Parent under this
Agreement shall continue to have, and be subject to, the same terms and
conditions set forth in the Company Stock Option Plan and agreement pursuant to
which such Company Option was issued as in effect immediately prior to the
Effective Time, except that (i) such Company Option will be exercisable for that
number of Parent Common Shares equal to the product of the number of shares of
Company Common Stock that were purchasable under such Company Option immediately
prior to the Effective Time multiplied by the Exchange Ratio, rounded up to the
nearest whole number of shares of Parent Common Shares, and (ii) the per share
exercise price for the shares of Parent Common Shares issuable upon exercise of
such assumed Company Option will be equal to the quotient determined by dividing
the exercise price per share of Company


<PAGE>
                                        37


Common Stock at which such Company Option was exercisable immediately prior to
the Effective Time by the Exchange Ratio, and rounding the resulting exercise
price up to the nearest whole cent.

          (b)  It is the intention of the parties that the Company Options
assumed by Parent qualify following the Effective Time as incentive stock
options as defined in the Code ("ISO's") to the extent the Company Options
qualified as ISO's prior to the Effective Time.

          (c)  After the Effective Time, Parent will issue to each holder of
an outstanding Company Option a document evidencing the foregoing assumption by
Parent.

          SECTION 5.06.  COMPANY EMPLOYEE STOCK PURCHASE PLAN.  (a)  The
Company shall take such actions as are necessary to cause the exercise date (as
such term is used in the Company's Employee Stock Purchase Plan (the "Company
Stock Purchase Plan")) applicable to the then current offering period (as such
term is used in the Company Stock Purchase Plan) to be the last trading day on
which the Parent Common Shares are traded on the New York Stock Exchange
immediately prior to the Effective Time (the "Final Company Purchase Date");
PROVIDED, THAT, such change in the Purchase Date shall be conditioned upon
the consummation of the Merger.  On the Final Company Purchase Date, the Company
shall apply the funds credited as of such date under the Company Stock Purchase
Plan within each participant's payroll withholdings account to the purchase of
whole shares of Company Common Stock in accordance with the terms of the Company
Stock Purchase Plan.  The cost to each participant in the Company Stock Purchase
Plan for shares of Company Common Stock shall be the lower of 85% of the closing
sale price of Company Common Stock on the Nasdaq National Market on (i) the
first day of the then current offering period or (ii) the Final Company Purchase
Date.

          (b)  Employees of the Company as of the Effective Time shall be
permitted to participate in Parent's Employee Stock Purchase Plan commencing on
the first enrollment date following the Effective Time, subject to compliance
with the eligibility provisions of such plan (with employees receiving credit,
for purposes of such eligibility provisions, for service with the Company).

          SECTION 5.07.  AGREEMENTS OF AFFILIATES.  The Company shall
deliver to Parent, prior to the date the Registration Statement becomes
effective under the Securities Act, a letter (the "Affiliate Letter")
identifying all persons who are, or may deemed to be, at the time of the Company
Stockholders' Meetings, "affiliates" of the Company for purposes of Rule 145
under the Securities Act.  The Company shall use its best efforts to cause each
person who is identified as an "affiliate" in the Affiliate Letter to deliver to
Parent, prior to the Effective Time, a written agreement (an "Affiliate
Agreement") in substantially the form of Exhibit A hereto.

          SECTION 5.08.  INDEMNIFICATION AND INSURANCE.  (a)  The Articles
of Incorporation of the Surviving Corporation shall contain the provisions with
respect to indemnification set forth in the By-Laws of the Company, which
provisions shall not be amended, repealed or otherwise modified for a period of
six years from the Effective Time in any manner that would adversely affect the
rights thereunder of individuals who at the Effective Time were directors,
officers, employees or agents of the Company, unless such modification is
required by law.

          (b)  The Company shall, to the fullest extent permitted under
applicable law or under the Company's Articles of Incorporation or By-Laws and
regardless of whether the Merger becomes effective, indemnify and hold harmless,
and after the Effective Time, the Surviving Corporation and Parent shall, to the
fullest extent permitted under applicable law or under the Surviving
Corporation's and Parent's, as the case may be, Articles of Incorporation or
By-Laws, indemnify and hold harmless, each present and former director, officer,
employee, fiduciary and agent of the Company or any of its subsidiaries
(collectively, the "Indemnified Parties") against any costs or expenses
(including attorneys' fees), judgments, fines, losses, claims, damages,
liabilities and amounts paid in settlement in connection with any claim, action,
suit, proceeding or investigation, whether civil, criminal, administrative or
investigative, arising out of or pertaining to any action or omission occurring
at or prior to the Effective Time (including, without limitation, the
transactions contemplated by this Agreement) for a period of six years after the
Effective Time.  In the event of any such claim, action, suit, proceeding or
investigation (whether arising before or after the Effective Time), (i) any
counsel retained by the Indemnified Parties for any period after the Effective
Time shall be reasonably satisfactory to the Surviving Corporation and Parent,
(ii) after the Effective Time, the Surviving Corporation and Parent shall pay
the reasonable fees and expenses of such counsel, and (iii) the Surviving
Corporation and Parent will cooperate in the defense of any such matter;
PROVIDED, HOWEVER, that neither the Surviving Corporation nor Parent shall
be liable for any settlement effected without its written consent (which consent
shall not be unreasonably withheld); and PROVIDED, FURTHER, that in the
event that any claim or claims for indemnification are asserted or made within
such six-year period, all rights to indemnification in respect of any such claim
or claims shall continue until the disposition of any and all such claims.  The
Indemnified Parties as a group may retain only one law firm to represent them
with respect to any single action unless there is, under applicable standards of
professional conduct, a conflict on any significant issue between the positions
of any two or more Indemnified Parties.

          SECTION 5.09.  NOTIFICATION OF CERTAIN MATTERS.  The Company shall
give prompt notice to Parent, and Parent shall give prompt notice to the
Company, of (i) the occurrence, or non-occurrence, of any event the occurrence,
or non-occurrence, of which would be likely to cause any representation or
warranty contained in this Agreement to be untrue or inaccurate, (ii) any
failure of the Company, Parent or Merger Sub, as the case may be, materially to
comply with or satisfy any covenant, condition or agreement to be complied


<PAGE>
                                        39


with or satisfied by it hereunder and (iii) any termination of the Other

this Section shall not limit or otherwise affect the remedies available
hereunder to the party receiving such notice; and PROVIDED, FURTHER, that
failure to give such notice shall not be treated as a breach of covenant for the
purposes of Sections 6.02(a) and 6.03(a) unless the failure to give such notice
results in material prejudice to the other party.

          SECTION 5.10.  FURTHER ACTION/TAX TREATMENT.  Upon the terms and
subject to the conditions hereof, each of the parties hereto in good faith shall
use all commercially reasonable efforts to take, or cause to be taken, all
actions and to do, or cause to be done, all other things necessary, proper or
advisable to consummate and make effective as promptly as practicable the
transactions contemplated by this Agreement, to obtain in a timely manner all
necessary waivers, consents and approvals and to effect all necessary
registrations and filings, and to otherwise satisfy or cause to be satisfied all
conditions precedent to its obligations under this Agreement.  Each of Parent,
Merger Sub and the Company shall use its best efforts to cause the Mergers to
qualify, and will not (both before and after consummation of the Mergers) take
any actions which could prevent the Mergers from qualifying as a reorganization
under the provisions of Section 368 of the Code.  Each of Parent, Merger Sub and
the Company shall report the Mergers as a reorganization under the provisions of
Section 368 of the Code and, to the extent permitted, on all state and local Tax
returns, filed after the Effective Time of the Mergers.

consult with each other before issuing any press release or otherwise making any
public statements with respect to the Merger or this Agreement and shall not
issue any such press release or make any such public statement without the prior
consent of the other party, which shall not be unreasonably withheld;
PROVIDED, HOWEVER, that a party may, without the prior consent of the other
party, issue such press release or make such public statement as may upon the
advice of counsel be required by law, the National Association of Securities
Dealers or the NYSE if it has used all reasonable efforts to consult with the
other party.

          SECTION 5.12.  LISTING OF PARENT COMMON SHARES.  Parent shall use
its reasonable best efforts to cause the shares of Parent Common Shares to be
issued in the Merger to be approved for listing on the New York Stock Exchange.

cooperate in the preparation, execution and filing of all returns,
questionnaires, applications or other documents regarding any real property
transfer or gains, sales, use, transfer, value added, stock transfer and stamp

Parent, the Company shall use its best efforts to cause Arthur Andersen &
Company LLP to deliver to Parent a letter covering such matters as are requested
by Parent and as are customarily addressed in accountant's "comfort" letters.

          SECTION 5.15.  POOLING ACCOUNTING TREATMENT.  Each of Parent and
the Company agree not to take any action that would adversely affect the ability
of Parent to treat the Mergers as a pooling of interests under GAAP.

Merger unless the Merger closes substantially contemporaneously therewith.

          SECTION 5.17.  OTHER MERGER EXCHANGE RATIO.  Parent shall not
increase the Other Merger Exchange Ratio, other than increasing such ratio in
response to an Acquisition Proposal with respect to Alias, without
proportionately increasing the Exchange Ratio.

     the cause of or resulted in the failure of the Merger to occur on or before

               (c)  by either Parent or the Company if a court of competent
     jurisdiction or governmental, regulatory or administrative agency or
     commission shall have issued a non-appealable final order, decree or ruling
     or taken any other action, in each case having the effect of permanently
     restraining, enjoining or otherwise prohibiting the Merger; or

          (d)  by Parent or the Company, if, at the Company Stockholders'
     Meeting (including any adjournment or postponement thereof), the requisite

          (e)  by Parent, if (i) the Board of Directors of the Company shall
     withdraw, modify or change its recommendation of this Agreement or the
     Merger in a manner adverse to Parent or shall have resolved to do so; or
     (ii) the Board of Directors of the Company shall have taken a "neutral"
     position with respect to (or shall have failed to reject as inadequate or
     failed to have reaffirmed its recommendation of this Agreement and the
     Merger within 10 business days after the public announcement or

     Section 7.03(d)); or

          (f)  by Parent or the Company, upon a breach of any representation,
     warranty, covenant or agreement on the part of the Company or Parent and
     Merger Sub, respectively, set forth in this Agreement or if any
     representation or warranty of the Company or Parent and Merger Sub,
     respectively, shall have become untrue, in either case, such that the
     conditions set forth in Section 6.02(a) or 6.02(b), or Section 6.03(a) or
     6.03(b), would not be satisfied (a "Terminating Breach"), PROVIDED that, if
     such Terminating Breach is curable prior to the expiration of 30 days from
     its occurrence (but in no event later than August 31, 1995) by Parent or
     the Company, as the case may be, through the exercise of its reasonable
     best efforts and for so long as Parent or the Company, as the case may be,
     continues to exercise such reasonable best efforts, neither the Company nor
     Parent, respectively, may terminate this Agreement under this Section
     7.01(f) unless such 30-day period expires without such Terminating Breach
     having been cured; or

          (g)  by the Company or Parent, if the Board of Directors of the
     Company shall have resolved to accept, or accepted, a Superior Proposal; or

          (h)  by the Company, at any time after the tenth business day
     following termination of the Other Merger Agreement; or

          (i)  by the Parent, at any time after the tenth business day
     following termination of the Other Merger Agreement.

          SECTION 7.02.  EFFECT OF TERMINATION.  In the event of the
termination of this Agreement pursuant to Section 7.01, this Agreement shall
forthwith become void and there shall be no liability on the part of any party
hereto or any of its affiliates, directors, officers or stockholders except (i)
as set forth in Section 7.03 and Section 8.01 hereof, and (ii) nothing herein
shall relieve any party from liability for any willful breach hereof (provided
that any fee paid pursuant to Section 7.03(b) or (c) shall be credited towards
any such liability of the paying party).  If the Board of Directors of the
Company, in good faith, after receiving the advice of outside counsel, concludes
that it would be in violation of its fiduciary duties if it did not take or omit
to take the actions enumerated in Section 7.01(e) as giving rise to a right of
termination by Parent, then any such action or omission shall not be considered
a breach of this Agreement.

          SECTION 7.03.  FEES AND EXPENSES.  (a)  Except as set forth in
this Section 7.03, all fees and expenses incurred in connection with this
Agreement and the transactions contemplated hereby shall be paid by the party

     Section 7.01(e); or

               (ii) the termination of this Agreement by Parent pursuant to
     Section 7.01(f) after a willful and material breach by the Company of this
     Agreement; or

               (iii)     the termination of this Agreement by Parent or the
     Company pursuant to Section 7.01(g); or

               (iv) the termination of this Agreement by the Company or
     Parent pursuant to Section 7.01(d) if, at the time of termination (and on
     the day of the vote referred to in Section 7.01(d)), an Alternative
     Transaction shall be outstanding or a proxy statement recommending the
     implementation of such Alternative Transaction shall have been published or
     sent or given to the holders of the Shares.

          (c)  (i)  The Company shall pay Parent a fee of $5,000,000 upon the
Company's termination of this Agreement pursuant to Section 7.01(h); PROVIDED,
THAT, no such fee shall be payable unless (A) the Other Merger Agreement has
been terminated as a result of a Third Party (as defined in Section 7.03(d))
having engaged in, or having entered into a contract to engage in, an
Alternative Transaction (as defined in the Other Merger Agreement) with Alias,
(B) prior to the expiration of the ten business day period referred to in
Section 7.01(h), Parent has delivered to the Company Parent's written waiver of
the


<PAGE>
                                        46


condition specified in Section 6.01(g) and (C) prior to the expiration of the
ten business day period referred to in Section 7.01(h), the Company has not
delivered to Parent the Company's written waiver of the condition specified in
Section 6.01(g).

               (ii) Parent shall pay the Company a fee of $5,000,000 upon
Parent's termination of this Agreement pursuant to Section 7.01(i); PROVIDED,
THAT, no such fee shall be payable unless (A) the Other Merger Agreement has
been terminated as a result of a Third Party having engaged in, or having
entered into a contract to engage in, an Alternative Transaction (as defined in
the Other Merger Agreement) with Alias, (B) prior to the expiration of the ten
business day period referred to in Section 7.01(i), the Company has delivered to
Parent the Company's written waiver of the condition specified in Section
6.01(g) and (C) prior to the expiration of the ten business day period referred
to in Section 7.01(i), Parent has not delivered to the Company Parent's written
waiver of the condition specified in Section 6.01(g).

          (d)  As used herein, "Alternative Transaction" means (i) a
transaction pursuant to which any person (or group of persons) other than Parent
or its affiliates (a "Third Party") acquires (or publicly proposes to acquire)
more than 50 percent of the outstanding Shares, whether from the Company or
pursuant to a tender offer or exchange offer or otherwise, (ii) a merger or
other business combination involving the Company pursuant to which any Third
Party acquires (or publicly proposes to acquire) more than 50 percent of the
outstanding equity securities of the Company or the entity surviving such merger
or business combination or (iii) any other transaction pursuant to which any
Third Party acquires (or publicly proposes to acquire) control of assets
(including for this purpose the outstanding equity securities of subsidiaries of
the Company, and the entity surviving any merger or business combination
including any of them) of the Company and its subsidiaries having a fair market
value equal to more than 50 percent of the fair market value of all the assets
of the Company and its subsidiaries, taken as a whole, immediately prior to such
transaction (or proposal).

          (e)  The fee payable pursuant to Section 7.03(b)(i), (ii) and (iii)
shall be paid within one business day after the first to occur of the events
described in Section 7.03(b)(i), (ii) and (iii).  The fee payable pursuant to
Section 7.03(c)(i) and (ii) shall be paid within one business day after the
dates of termination referred to therein.  The fee payable pursuant to Section
7.03(b)(iv) shall be paid on the date of the closing of the Alternative
Transaction giving rise to such termination, PROVIDED, HOWEVER, that if such
Alternative Transaction is not closed within twelve months of such termination,
the fee shall not be payable.  In no event shall the Company or Parent be
required to pay any fee pursuant to Section 7.03(b) or (c) if, immediately prior
to the termination of the Agreement, the party to whom the fee is due was in
material breach of its obligations under this Agreement.

                                        49


          SECTION 8.04.  AMENDMENT.  This Agreement may be amended by the
parties hereto by action taken by or on behalf of their respective Boards of
Directors at any time prior to the Effective Time; PROVIDED, HOWEVER, that,
after approval of the Merger by the stockholders of the Company, no amendment
may be made which by law requires further approval by such stockholders without
such further approval.  This Agreement may not be amended except by an
instrument in writing signed by the parties hereto; PROVIDED, HOWEVER, that,
prior to the Effective Time, Parent may, by an instrument signed only by Parent,
amend this Agreement solely to cause the Mergers to be effected as a forward
merger of the Company with and into Parent.

          SECTION 8.05.  WAIVER.  At any time prior to the Effective Time,
any party hereto may with respect to any other party hereto (a) extend the time
for the performance of any of the obligations or other acts, (b) waive any
inaccuracies in the representations and warranties contained herein or in any
document delivered pursuant hereto and (c) waive compliance with any of the
agreements or conditions contained herein.  Any such extension or waiver shall
be valid if set forth in an instrument in writing signed by the party or parties
to be bound thereby.

          SECTION 8.06.  HEADINGS.  The headings contained in this Agreement
are for reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

          SECTION 8.07.  SEVERABILITY.  If any term or other provision of
this Agreement is invalid, illegal or incapable of being enforced by any rule of
law, or public policy, all other conditions and provisions of this Agreement
shall nevertheless remain in full force and effect so long as the economic or
legal substance of the transactions contemplated hereby is not affected in any
manner adverse to any party.  Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in an acceptable manner to
the end that transactions contemplated hereby are fulfilled to the extent
possible.

          SECTION 8.08.  ENTIRE AGREEMENT.  This Agreement constitutes the
entire agreement and supersedes all prior agreements and undertakings (other
than the Confidentiality Agreement), both written and oral, among the parties,
or any of them, with respect to the subject matter hereof and, except as
otherwise expressly provided herein, are not intended to confer upon any other
person any rights or remedies hereunder.

          SECTION 8.09.  ASSIGNMENT, MERGER SUB.  This Agreement shall not
be assigned by operation of law or otherwise, except that Parent and Merger Sub
may assign all or any of their rights hereunder to any affiliate provided that
no such assignment shall relieve


<PAGE>
                                        50


the assigning party of its obligations hereunder.  Parent guarantees the full
and punctual performance by Merger Sub of all of the obligations hereunder of
Merger Sub.

          SECTION 8.10.  PARTIES IN INTEREST.  This Agreement shall be
binding upon and inure solely to the benefit of each party hereto, and nothing
in this Agreement, express or implied, is intended to or shall confer upon any
other person any right, benefit or remedy of any nature whatsoever under or by
reason of this Agreement, other than Section 5.08 (which is intended to be for
the benefit of the Indemnified Parties and may be enforced by such Indemnified
Parties).

          SECTION 8.11.  FAILURE OR INDULGENCE NOT WAIVER; REMEDIES
CUMULATIVE.  No failure or delay on the part of any party hereto in the
exercise of any right hereunder shall impair such right or be construed to be a
waiver of, or acquiescence in, any breach of any representation, warranty or
agreement herein, nor shall any single or partial exercise of any such right
preclude other or further exercise thereof or of any other right.  All rights
and remedies existing under this Agreement are cumulative to, and not exclusive
of, any rights or remedies otherwise available.

          SECTION 8.12.  GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED
BY, AND CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF
CALIFORNIA APPLICABLE TO CONTRACTS EXECUTED AND FULLY PERFORMED WITHIN THE STATE
OF CALIFORNIA.

          SECTION 8.13.  COUNTERPARTS.  This Agreement may be executed in
one or more counterparts, and by the different parties hereto in separate
counterparts, each of which when executed shall be deemed to be an original but
all of which taken together shall constitute one and the same agreement.

          SECTION 8.14.  WAIVER OF JURY TRIAL.  EACH OF PARENT, MERGER SUB
AND THE COMPANY HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY
LAW, ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM
(WHETHER BASED UPON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO
THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY.

Silicon Graphics, Inc.
2011 N. Shoreline Blvd.
Mail Stop 710
Mountain View, CA 94043-1389
Attention:  Legal Services

Ladies and Gentlemen:

          Pursuant to the terms of the Agreement and Plan of Merger dated as
of February 6, 1995 (the "Agreement"), among Silicon Graphics, Inc., a Delaware
corporation ("Parent"), S Acquisition Corporation, a California corporation and
wholly owned subsidiary of Parent ("Merger Sub"), and Wavefront Technologies,
Inc., a California corporation (the "Company"), Parent will acquire the Company
through the merger of Merger Sub with and into the Company (the "Merger").
Subject to the terms and conditions of the Agreement, at the Effective Time (as
defined in the Agreement), outstanding shares of the common stock, no par value,
of the Company (the "Company Common Stock") will be converted into the right to
receive shares of the common stock, par value $0.001 per share, of Parent (the
"Parent Common Stock"), on the basis described in the Agreement.

          The undersigned has been advised that as of the date hereof it may
be deemed to be an "affiliate" of the Company, as the term "affiliate" is (i)
defined for purposes of paragraphs (c) and (d) of Rule 145 of the Rules and
Regulations (the "Rules and Regulations") of the Securities and Exchange
Commission (the "Commission") under the Securities Act of 1933, as amended (the
"Act"), and/or (ii) used in and for purposes of Accounting Series Releases 130
and 135, as amended, and Staff Accounting Bulletins 65 and 76 of the Commission.

          The undersigned understands that the representations, warranties and
covenants set forth herein will be relied upon by Parent, stockholders of
Parent, the Company, other shareholders of the Company and their respective
counsel and accountants.

                                        2



          The undersigned represents and warrants to and agrees with Parent
that:

          1.   The undersigned has full power to execute and deliver this
Affiliate Agreement and to make the representations and warranties herein and to
perform its obligations hereunder.

          2.   The undersigned has carefully read this letter and the
Agreement and discussed its requirements and other applicable limitations upon
its ability to sell, transfer or otherwise dispose of Parent Common Stock to the
extent the undersigned felt necessary, with its counsel or counsel for the
Company.

          3.   The undersigned shall not make any sale, transfer or other
disposition of Parent Common Stock in violation of the Act or the Rules and
Regulations.

          4.   The undersigned has been advised that the issuance of shares
of Parent Common Stock to the undersigned in connection with the Merger has been
or will be registered with the Commission under the Act on a Registration
Statement on Form S-4.  However, the undersigned has also been advised that,
since at the time the Merger was submitted for a vote of the shareholders of the
Company the undersigned may be deemed to have been an affiliate of the Company
and the distribution by the undersigned of any Parent Common Stock has not been
registered, and is not exempt, under the Act, the undersigned may not sell,
transfer or otherwise dispose of Parent Common Stock issued to the undersigned
in the Merger unless (i) such sale, transfer or other disposition has been
registered under the Act, (ii) such sale, transfer or other disposition is made
in conformity with the requirements of Rule 145 promulgated by the Commission
under the Act, or (iii) in the opinion of counsel reasonably acceptable to
Parent, such sale, transfer or other disposition is otherwise exempt from
registration under the Act.

          5.   Parent is under no obligation to register the sale, transfer
or other disposition of Parent Common Stock by the undersigned or on its behalf
under the Act or to take any other action necessary in order to make compliance
with an exemption from such registration available.

          6.   Stop transfer instructions will be given to Parent's transfer
agent with respect to the Parent Common Stock and that there will be placed on
the certificates for the Parent Common Stock issued to the undersigned, or any
substitutions therefor, a legend stating in substance:

          "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A
TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933
APPLIES.  THE SHARES REPRESENTED BY THIS CERTIFICATE MAY ONLY BE TRANSFERRED IN
ACCORDANCE WITH THE


<PAGE>
                                        3


TERMS OF AN AGREEMENT DATED __________, 1995 BETWEEN THE REGISTERED HOLDER
HEREOF AND SILICON GRAPHICS, INC., A COPY OF WHICH AGREEMENT IS ON FILE AT THE
PRINCIPAL OFFICES OF SILICON GRAPHICS, INC."

          7.   Unless the transfer by the undersigned of its Parent Common
Stock has been registered under the Act or is a sale made in conformity with the
provisions of Rule 145, Parent reserves the right to put the following legend on
the certificates issued any transferee of the undersigned:

          "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933 AND WERE ACQUIRED FROM A PERSON WHO
     RECEIVED SUCH SHARES IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER
     THE SECURITIES ACT OF 1933 APPLIES.  THE SHARES HAVE BEEN ACQUIRED BY THE
     HOLDER NOT WITH A VIEW TO, OR FOR RESALE IN CONNECTION WITH, ANY
     DISTRIBUTION THEREOF WITHIN THEMEANING OF THE SECURITIES ACT OF 1933 AND
     MAY NOT BE SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH
     AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF
     1933."

          8.   The legends set forth in paragraphs 6 and 7 above shall be
removed by delivery of substitute certificates without such legend if the
undersigned shall have delivered to Parent a copy of a letter from the staff of
the Commission, or an opinion of counsel in form and substance reasonably
satisfactory to Parent, to the effect that such legend is not required for
purposes of the Act.

          9.   The undersigned is the beneficial owner of (i.e. has sole or
shared voting or investment power with respect to) all the shares of Company
Common Stock and options to purchase Company Common Stock indicated on the last
page hereof (the "Company Securities").  Except for the Company Securities, the
undersigned does not beneficially own any shares of Company Common Stock or any
other equity securities of the Company or any options, warrants or other rights
to acquire any equity securities of the Company.

          10.  Notwithstanding any other provision hereof to the contrary,
the undersigned has not at any time since February 6, 1995 or in contemplation
of the Merger engaged, and will not, after the Effective Time (as defined in the

Common Stock in the Company's registered offering pursuant to its final
prospectus dated December 5, 1994):

          (a)  any shares of Parent Common Stock which the undersigned may
     acquire in connection with the Merger, or any securities which may be paid
     as a dividend or otherwise distributed thereon or with respect thereto or
     issued or delivered in exchange or substitution therefor (all such shares
     and other securities being referred to herein, collectively, as "Restricted
     Securities"), or any option, right or other interest with respect to any
     Restricted Securities;

          (b)  any Company Securities; or

          (c)  any shares of Company Common Stock or other Company equity
     securities which the undersigned purchases or otherwise acquires after the
     execution of this Affiliate Agreement.

          11.  As promptly as practicable following the Merger, Parent shall
publish results covering at least 30 days of combined operations of the Company
and Parent in the form of a quarterly earnings report, an effective registration
statement filed with the Commission, a report to the Commission on Form 10-K,
10-Q or 8-K, or any other public filing or announcement which includes the
combined results of operations; PROVIDED, HOWEVER, that Parent shall be
under no obligation to publish any such financial information other than with
respect to a fiscal quarter of Parent.

          12.  The undersigned intends to vote all Company Common Stock held
by him in favor of the Merger.

                AGREEMENT AND PLAN OF ACQUISITION AND ARRANGEMENT


          AGREEMENT AND PLAN OF ACQUISITION AND ARRANGEMENT, dated as of

Delaware corporation ("Parent"), 1103707 ONTARIO INC., an Ontario corporation
and a wholly owned subsidiary of Parent ("Amalgamation Sub"), SILICON GRAPHICS
MANUFACTURING S.A., a Swiss corporation and subsidiary of Parent ("Swissco"),
and ALIAS RESEARCH INC., an Ontario corporation (the "Company"),


                              W I T N E S S E T H:


          WHEREAS, the Boards of Directors of Parent and the Company have each
determined that it is advisable and in the best interests of their respective
stockholders for Parent to acquire shares in the capital stock of the Company
upon the terms and subject to the conditions set forth herein;

          WHEREAS, in furtherance of such acquisition, the Boards of Directors
of Parent, Amalgamation Sub, Swissco and the Company have each approved the
execution and delivery of this Agreement in order to provide for (i) the
amalgamation (the "Amalgama- tion") of Amalgamation Sub and the Company
whereupon each outstanding share (a "Share") of the Company's common shares (the
"Company Common Stock") shall be converted into Class A Shares or Class B Shares
(each as defined in the Plan of Arrangement), as the case may be, of the
continuing corporation in the Amalgamation (the "Continuing Corporation") and
(ii) the exchange of such Class A Shares and Class B Shares of the Continuing
Corporation for Parent Common Shares and/or Exchangeable Shares (each as defined
in the Plan of Arrangement) (the transactions specified in subclauses (i) and
(ii) being collectively referred to herein as the "Arrangement");

          WHEREAS, the Arrangement shall be effectuated under Section 182 of the
Business Corporations Act (Ontario) (the "OBCA") pursuant to the terms hereof
and a plan of arrangement (the "Plan of Arrangement") substantially in the form
of Exhibit A hereto;

          WHEREAS, in connection with the Arrangement, and after giving effect
thereto, holders of Company Common Stock will receive, at their election, in
respect of each share of Company Common Stock held by them immediately before
the implementation of the Arrangement, 0.90 (the "Exchange Ratio") shares of
Parent Common Stock from Swissco, or Exchangeable Shares from the Continuing
Corporation subject to proration in certain instances;


<PAGE>

                                        2

          WHEREAS, the Exchangeable Shares are exchangeable by the holders for
Parent Common Shares on a one-for-one basis at any time;

          WHEREAS, for accounting purposes, it is intended that the transactions
contemplated hereby shall be accounted for as a pooling of interests under
United States generally accepted accounting principles ("GAAP");

          WHEREAS, concurrently herewith, Parent, S Acquisition Corporation, a
California corporation and a wholly owned subsidiary of Parent, and Wavefront
Technologies, Inc., a California corporation ("Wavefront"), have executed an
Agreement and Plan of Merger and Reorganization, dated as of February 6, 1995
(the "Other Merger Agreement"), pursuant to which Parent will acquire Wavefront
as provided for therein (the "Other Merger"); and

          WHEREAS, the exchange ratio set forth in the Other Merger Agreement is
0.49 (the "Other Exchange Ratio");

          NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements herein contained, and intending to be legally bound
hereby, Parent, Swissco, Amalgamation Sub and the Company hereby agree as
follows:


                                    ARTICLE I

                                 THE ARRANGEMENT

          SECTION 1.01.  THE ARRANGEMENT.  (a)  EFFECTIVE DATE.  On the
Effective Date (as defined in Section 1.02 hereof), and subject to and upon the
terms and conditions of the Arrangement, this Agreement and the OBCA, (i)
Amalgamation Sub shall be amalgamated with the Company and (ii) the share
exchanges and conversions contemplated by Article 2 of the Plan of Arrangement
shall be completed in the manner set forth in the Plan of Arrangement.

          (b)  CLOSING.  Unless this Agreement shall have been terminated and
the transactions herein contemplated shall have been abandoned pursuant to
Section 7.01 hereof, and subject to the satisfaction or waiver of the conditions
set forth in Article VI hereof, the consummation of the Arrangement will take
place as promptly as practicable after satisfaction or waiver of the conditions
set forth in Article VI hereof, at the offices of Shearman & Sterling, 555
California Street, Suite 2000, San Francisco, California, unless another date,
time or place is agreed to in writing by the parties hereto.  At the closing,
the parties hereto shall deliver the documents contemplated hereby together with
such other customary documents as may be reasonably requested by the parties.


<PAGE>

                                        3

          SECTION 1.02.  EFFECTIVE DATE.  As promptly as practicable after the
satisfaction or waiver of the other conditions set forth in Article VI, the
parties hereto shall cause the Arrangement to be consummated by obtaining final
court approval of the Plan of Arrangement and by filing articles of arrangement
as contemplated by Section 182 of the OBCA (the "Articles of Arrangement"),
together with any required related certificates, with the Ministry of Consumer
and Commercial Relations of the Province of Ontario, in such form as required
by, and executed in accordance with the relevant provisions of, the OBCA (the
day of such filing being the "Effective Date").

          SECTION 1.03.  ACCOUNTING CONSEQUENCES.  It is intended by the parties
hereto that the Arrangement shall qualify for accounting treatment as a pooling
of interests under GAAP.

          SECTION 1.04.  MATERIAL ADVERSE EFFECT.  When used in connection with
the Company or any of its subsidiaries, or Parent or any of its subsidiaries, as
the case may be, the term "Material Adverse Effect" means any change or effect
that, individually or when taken together with all other such changes or effects
that have occurred prior to the date of determination of the occurrence of the
Material Adverse Effect, is or is reasonably likely to be materially adverse to
the business, assets (including intangible assets), financial condition or
results of operations of the Company and its subsidiaries or Parent and its
subsidiaries, as the case may be, in each case taken as a whole.  For the
purposes of determining whether a Material Adverse Effect has occurred with
respect to the Company under Section 6.02(a) and (e), any material decline in
the Company's consolidated gross sales revenues after the date hereof shall not
be considered a Material Adverse Effect with respect to the Company if (i) such
decline in sales is directly attributable to (A) a decrease in sales associated
with customers delaying orders or purchases pending completion of the
Arrangement or (B) a significant price reduction by any major competitor of the
Company, (ii) the Company has complied with its respective obligations under
Section 4.01 hereof and (iii) the Company has continued to develop, market,
supply and service its products.

          SECTION 1.05.  ADJUSTMENTS TO EXCHANGE RATIO.  The Exchange Ratio
shall be adjusted to reflect fully the effect of any stock split, reverse split,
stock dividend (including any dividend or distribution of securities convertible
into Parent Common Shares or Company Common Stock), reorganization,
recapitalization or other like change with respect to Parent Common Shares or
Company Common Stock occurring after the date hereof and prior to the Effective
Date.

          SECTION 1.06.  CANCELLATION.  Prior to the Effective Date, each Share
owned by Parent, Swissco, Amalgamation Sub or any direct or indirect wholly
owned subsidiary of the Company or Parent shall be purchased for cancellation by
the Company for nominal consideration.


<PAGE>

                                        4

          SECTION 1.07.  CAPITAL STOCK OF AMALGAMATION SUB.  Each stock
certificate of Amalgamation Sub evidencing ownership of any common shares of
Amalgamation Sub shall continue to evidence ownership of Class A Shares of
capital stock of the Continuing Corporation.

          SECTION 1.08.  DISSENTERS' RIGHTS.  The Company shall give Parent (i)
prompt notice of any written demand of a right of dissent, withdrawals of such
demands, and any other instruments served pursuant to the OBCA and received by
the Company and (ii) the opportunity to participate in all negotiations and
proceedings with respect to such rights.  The Company shall not, except with the
prior written consent of Parent, voluntarily make any payment with respect to
any such rights or offer to settle or settle any such rights.


                                   ARTICLE II

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

          The Company hereby represents and warrants to Parent, Swissco and
Amalgamation Sub that:

          SECTION 2.01.  ORGANIZATION AND QUALIFICATION; SUBSIDIARIES.  (a)
The Company and each of its subsidiaries is a corporation or limited liability
company duly organized, validly existing and in good standing under the laws of
the jurisdiction of its incorporation or organization and has the requisite
corporate power and authority and is in possession of all franchises, grants,
authorizations, licenses, permits, easements, consents, certificates, approvals
and orders ("Approvals") necessary to own, lease and operate the properties it
purports to own, operate or lease and to carry on its business as it is now
being conducted, except where the failure to be so organized, existing and in
good standing or to have such power, authority and Approvals would not have a
Material Adverse Effect.  Each of the Company and each of its subsidiaries is
duly qualified or licensed as a foreign corporation or limited liability company
to do business, and is in good standing, in each jurisdiction where the
character of its properties owned, leased or operated by it or the nature of its
activities makes such qualification or licensing necessary, except for such
failures to be so duly qualified or licensed and in good standing that would not
have a Material Adverse Effect.  A true and complete list of all of the
Company's subsidiaries, together with the jurisdiction of incorporation or
organization of each subsidiary and the percentage of each subsidiary's
outstanding capital stock owned by the Company or another subsidiary, is set
forth in Section 2.01 of the written disclosure schedule previously delivered by
the Company to Parent (the "Company Disclosure Schedule").  Except as set forth
in Section 2.01 of the Company Disclosure Schedule, the Company does not
directly or indirectly own any equity or similar interest in, or any interest
convertible into or exchangeable or exercisable for, any


<PAGE>

                                        5

equity or similar interest in, any corporation, partnership, joint venture or
other business association or entity.

          SECTION 2.02.  ARTICLES OF INCORPORATION AND BY-LAWS.  The Company has
heretofore furnished to Parent a complete and correct copy of its Restated
Articles of Incorporation and By-Laws, as amended to date, and equivalent
organizational documents of each of its subsidiaries.  Such Restated Articles of
Incorporation, By-Laws and equivalent organizational documents of each of its
subsidiaries are in full force and effect.  Neither the Company nor any of its
subsidiaries is in violation of any of the provisions of its Articles of
Incorporation or By-Laws or equivalent organizational documents.

          SECTION 2.03.  CAPITALIZATION.  The authorized capital stock of the
Company consists of an unlimited number of shares of Company Common Stock and an
unlimited number of shares of special shares, no par value (the "Company Special
Shares").  As of January 31, 1995, (i) 10,960,745 shares of Company Common Stock
were issued and outstanding, all of which are validly issued, fully paid and
nonassessable, (ii) no shares of Company Common Stock were held by subsidiaries
of the Company, (iii) 159 shares of Company Common Stock were reserved for
future issuance pursuant to option grants under the Company's 1988 Employee
Share Ownership Plan, (iv) 4,533 shares of Company Common Stock were reserved
for future issuance pursuant to option grants under the Company's 1989 Employee
Share Ownership Plan, (v) 1,209,371 shares of Company Common Stock were reserved
for future issuance pursuant to option grants under the Company's 1990 Employee
Share Ownership Plan, (vi) 1,000,000 shares of Company Common Stock were
reserved for future issuance pursuant to option grants under the Company's 1993
Employee Stock Purchase Plan, (vii) 813,101 shares of Company Common Stock were
reserved for future issuance pursuant to option grants under the Company's 1994
Stock Plan, (viii) 55,172 shares of Company Common Stock were reserved for
issuance with respect to the $400,000 Convertible Debenture of the Company
issued to Robert Burgess as of February 2, 1993 and (ix) no shares of Company
Special Shares were issued or outstanding.  No material change in such
capitalization has occurred between January 31, 1995 and the date hereof, except
for the issuance of shares under the exercise of options, warrants or other
rights outstanding prior to January 31, 1995.  Except as is provided by the
Company's 1993 Stock Purchase Plan or as set forth in this Section 2.03 or
Section 2.11 hereof or in Section 2.03 or Section 2.11 of the Company Disclosure
Schedule, there are no options, warrants or other rights, agreements,
arrangements or commitments of any character relating to the issued or unissued
capital stock of the Company or any of its subsidiaries obligating the Company
or any of its subsidiaries to issue or sell any shares of capital stock of, or
other equity interests in, the Company or any of its subsidiaries.  All shares
of Company Common Stock subject to issuance as aforesaid, upon issuance on the
terms and conditions specified in the instruments pursuant to which they are
issuable, shall be duly authorized, validly issued, fully paid and
nonassessable.  There are no obligations, contingent or otherwise, of the
Company or any of its subsidiaries to repurchase, redeem or otherwise

                                        6

acquire any shares of Company capital stock or the capital stock of any
subsidiary or to provide funds to or make any investment (in the form of a loan,
capital contribution or otherwise) in any such subsidiary or any other entity
other than guarantees of bank and capital or other lease obligations of
subsidiaries entered into in the ordinary course of business.  All of the
outstanding shares of capital stock of each of the Company's subsidiaries are
duly authorized, validly issued, fully paid and nonassessable, and all such
shares are owned by the Company or another subsidiary free and clear of all
security interests, liens, claims, pledges, agreements, limitations in the
Company's voting rights, charges or other encumbrances of any nature whatsoever.

          SECTION 2.04.  AUTHORITY RELATIVE TO THIS AGREEMENT.  The Company has
all necessary corporate power and authority to execute and deliver this
Agreement and to perform its obligations hereunder and to consummate the
transactions contemplated hereby.  The execution and delivery of this Agreement
by the Company and the consummation by the Company of the transactions
contemplated hereby have been duly and validly authorized by all necessary
corporate action and no other corporate proceedings on the part of the Company
are necessary to authorize this Agreement or to consummate the transactions so
contemplated (other than the approval and adoption of the Arrangement by the
holders of at least two-thirds of the outstanding shares of Company Common Stock
who are permitted to, and who, vote in accordance with the OBCA, the Securities
Act (Ontario) (the "OSA") and the Company's Articles of Incorporation and By-
Laws and the approval of the court in accordance with the OBCA).  The Board of
Directors of the Company has determined that it is advisable and in the best
interest of the Company's stockholders for the Company to enter into a business
combination with Parent upon the terms and subject to the conditions of this
Agreement.  This Agreement has been duly and validly executed and delivered by
the Company and, assuming the due authorization, execution and delivery by
Parent, Swissco and Amalgamation Sub, as applicable, constitutes a legal, valid
and binding obligation of the Company.

          SECTION 2.05.  NO CONFLICT; REQUIRED FILINGS AND CONSENTS.
(a)  Section 2.05(a) of the Company Disclosure Schedule includes a list of (i)
all material contracts of the Company and its subsidiaries and (ii) all
agreements which, as of the date hereof, will be required to be filed with the
Securities and Exchange Commission ("SEC") pursuant to the requirements of the
Securities Exchange Act of 1934, as amended, and the SEC's rules thereunder
(collectively, the "Exchange Act") as "material contracts" ((i) and (ii) being,
collectively, the "Material Contracts") of the Company and its subsidiaries.

          (b)  The execution and delivery of this Agreement by the Company do
not, and the performance of this Agreement by the Company will not, (i) conflict
with or violate the Articles of Incorporation or By-Laws or equivalent
organizational documents of the Company or any of its subsidiaries,
(ii) conflict with or violate any law, rule, regulation, order, judgment or
decree applicable to the Company or any of its subsidiaries or by which


<PAGE>

                                        7

its or any of their respective properties is bound or affected, or (iii) result
in any breach of or constitute a default (or an event that with notice or lapse
of time or both would become a default), or impair the Company's or any of its
subsidiaries' rights or alter the rights or obligations of any third party
under, or give to others any rights of termination, amendment, acceleration or
cancellation of, any Material Contract, or result in the creation of a lien or
encumbrance on any of the properties or assets of the Company or any of its
subsidiaries pursuant to any note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise or other instrument or obligation
to which the Company or any of its subsidiaries is a party or by which the
Company or any of its subsidiaries or its or any of their respective properties
is bound or affected.

          (c)  The execution and delivery of this Agreement by the Company does
not, and the performance of this Agreement by the Company will not, require any
consent, approval, authorization or permit of, or filing with or notification
to, any governmental or regulatory authority, domestic or foreign, except
(i) for applicable requirements, if any, of the Securities Act of 1933, as
amended, (the "Securities Act"), the Exchange Act, state securities laws ("Blue
Sky Laws"), the pre-merger notification requirements of the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the "HSR Act"), the OSA and
other relevant Canadian securities statutes, filings with the agency under the
Investment Canada Act and filings under the Competition Act (Canada) and the
filing and recordation of appropriate amalgamation, arrangement or other
documents as required by the OBCA and (ii) where the failure to obtain such
consents, approvals, authorizations or permits, or to make such filings or
notifications, would not prevent or delay consummation of the Arrangement, or
otherwise prevent or delay the Company from performing its obligations under
this Agreement, or would not otherwise have a Material Adverse Effect.

          SECTION 2.06.  COMPLIANCE; PERMITS.  (a)  Neither the Company nor any
of its subsidiaries is in conflict with, or in default or violation of, (i) any
law, rule, regulation, order, judgment or decree applicable to the Company or
any of its subsidiaries or by which its or any of their respective properties is
bound or affected or (ii) any note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise or other instrument or obligation
to which the Company or any of its subsidiaries is a party or by which the
Company or any of its subsidiaries or its or any of their respective properties
is bound or affected, except for any such conflicts, defaults or violations
which would not have a Material Adverse Effect.

          (b)  The Company and its subsidiaries hold all permits, licenses,
easements, variances, exemptions, consents, certificates, orders and approvals
from governmental authorities that are material to the operation of the business
of the Company and its subsidiaries (collectively, the "Company Permits").  The
Company and its subsidiaries are in compliance with the terms of the Company
Permits, except where the failure to so comply would not have a Material Adverse
Effect.

                                        8

          SECTION 2.07.  SEC FILINGS; FINANCIAL STATEMENTS.  (a)  The Company
has filed all forms, reports and documents required to be filed with the SEC
since January 31, 1991 and has made available to Parent (i) its Annual Reports
on Form 10-K for the fiscal years ended January 31, 1992, 1993 and 1994,
respectively, (ii) its Quarterly Reports on Form 10-Q for the periods ended
April 31, July 31 and October 31, 1994, respectively, (iii) all proxy statements
relating to the Company's meetings of stockholders (whether annual or special)
held since January 31, 1992, (iv) all other reports or registration statements
(other than Reports on Form 10-Q not referred to in clause (ii) above) filed by
the Company with the SEC since January 31, 1992, and (v) all amendments and
supplements to all such reports and registration statements filed by the Company
with the SEC (collectively, the "Company SEC Reports").  The Company SEC Reports
(i) were prepared in accordance with the requirements of the Securities Act or
the Exchange Act, as the case may be, and (ii) did not at the time they were
filed (or if amended or superseded by a filing prior to the date of this
Agreement, then on the date of such amending or superseding filing) contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading.  None of
the Company's subsidiaries is required to file any forms, reports or other
documents with the SEC.

          (b)  Each of the consolidated financial statements (including, in each
case, any related notes thereto) contained in the Company SEC Reports was
prepared in accordance with Canadian generally accepted accounting principles
("Canadian GAAP") applied on a consistent basis throughout the periods involved
(except as may be indicated therein or in the notes thereto) and each fairly
presented the consolidated financial position of the Company and its
subsidiaries as at the respective dates thereof and the consolidated results of
its operations and cash flows for the periods indicated, except that the
unaudited interim financial statements were or are subject to normal and
recurring year-end adjustments which were not or are not expected to be material
in amount.  The audited financial statements of the Company for its fiscal year
ended January 31, 1995, will not, when delivered, be materially and adversely
different from the financial information for such fiscal year previously
delivered by the Company to Parent in connection with this Agreement.

          (c)  Since January 31, 1992, the Company has filed all forms, reports
and documents with the Ontario Securities Commission (the "OSC") required to be
filed by it pursuant to the OSA and the regulations promulgated thereunder and
the applicable policies of the OSC (collectively, the "Company OSC Reports"),
all of which have complied in all material respects with all applicable
requirements of such statute, regulations and policies.  None of the Company OSC
Reports, at the time filed or as subsequently amended, contained any untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary in order to make the statements made therein, in
light of the circumstances under which they were made, not misleading.  The
Company has furnished to Parent all Company OSC Reports.  The Company has
complied in all material respects with


<PAGE>

legislation, regulations and policy statements.

          SECTION 2.08.  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as set

ordinary course and there has not occurred:  (i) any Material Adverse Effect,
(ii) any amendments or changes in the Articles of Incorporation or Bylaws of the
Company, (iii) any damage to, destruction or loss of any assets of the Company
(whether or not covered by insurance) that could have a Material Adverse Effect,

practices, (v) any revaluation by the Company of any of its assets, including,
without limitation, writing down the value of capitalized software or inventory
or writing off notes or accounts receivable other than in the ordinary course of
business, (vi) except as disclosed in Section 2.08 of the Company Disclosure
Schedule, any other action or event that would have required the consent of
Parent pursuant to Section 4.01 hereof had such action or event occurred after
the date of this Agreement or (vii) any sale of a material amount of property of
the Company, except for the sale of inventory in the ordinary course of
business.

          SECTION 2.09.  NO UNDISCLOSED LIABILITIES.  Except as is disclosed in
Section 2.09 of the Company Disclosure Schedule, neither the Company nor any of
its subsidiaries has any liabilities (absolute, accrued, contingent or
otherwise) which are, in the aggregate, material to the business, operations or
financial condition of the Company and its subsidiaries on a consolidated basis,
except liabilities (a) adequately provided for in the Company's audited balance
sheet (including any related notes thereto) for the fiscal year ended
January 31, 1994 included in the Company SEC Reports (the "1994 Balance Sheet"),
(b) incurred in the ordinary course of business and not required under Canadian
GAAP to be reflected on the 1994 Balance Sheet, (c) disclosed in the Company SEC
Reports or (d) incurred since January 31, 1994 in the ordinary course of
business and consistent with past practice, and liabilities incurred in
connection with this Agreement.

          SECTION 2.10.  ABSENCE OF LITIGATION.  Except as set forth in
Section 2.10 of the Company Disclosure Schedule or the Company SEC Reports,
there are no claims, actions, suits, proceedings or investigations pending or,
to the knowledge of the Company, threatened against the Company or any of its
subsidiaries, or any properties or rights of the Company or any of its
subsidiaries, before any court, arbitrator or administrative, governmental or
regulatory authority or body, domestic or foreign, that could have a Material
Adverse Effect.

          SECTION 2.11.  EMPLOYEE BENEFIT PLANS; EMPLOYMENT AGREEMENTS.
(a)  Section 2.11(a) of the Company Disclosure Schedule lists all employee
benefit plans (as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA")), regardless of whether ERISA is
applicable thereto, all other bonus,

any default or violation by any other party to, any of the Employee Plans; (iv)
each Employee Plan intended to qualify under Section 401(a) of the Code and each
trust intended to qualify under Section 501(a) of the Code is the subject of a
favorable determination letter from the Internal Revenue Service (the "IRS"),
and so far as the Company is aware nothing has occurred which may reasonably be
expected to impair such determination; (v) all contributions required to be made

described in Section 4062, 4063 or 4041 of ERISA has occurred; and (vii) neither

                                       13

Notwithstanding the foregoing, the Company makes no representation or warranty
with respect to any information supplied by Parent or Amalgamation Sub which is
contained in any of the foregoing documents.

          SECTION 2.14.  RESTRICTIONS ON BUSINESS ACTIVITIES.  Except for this
Agreement, there is no material agreement, judgment, injunction, order or decree
binding upon the Company or any of its subsidiaries which has or could
reasonably be expected to have the effect of prohibiting or impairing any
material business practice of the Company or any of its subsidiaries, the
acquisition of property by the Company or any of its subsidiaries or the conduct
of business by the Company or any of its subsidiaries as currently conducted or
as proposed to be conducted by the Company.

          SECTION 2.15.  TITLE TO PROPERTY.  The Company owns no real property.
Section 2.15(b) of the Company Disclosure Statement sets forth a true and
complete list of all real property leased by the Company or any of its
subsidiaries requiring annual lease payments of more than $50,000, and the
aggregate monthly rental or other fee payable under such lease.  The Company and
each of its subsidiaries have good, marketable and defensible title to all of
their properties and assets, free and clear of all liens, charges and
encumbrances except liens for taxes not yet due and payable and such liens or
other imperfections of title, if any, as do not materially detract from the
value of or interfere with the present use of the property affected thereby or
which would not have a Material Adverse Effect; and all leases pursuant to which
the Company or any of its subsidiaries lease from others material amounts of
real or personal property, are in good standing, valid and effective in
accordance with their respective terms, and there is not, under any of such
leases, any existing material default or event of default (or event which with
notice or lapse of time, or both, would constitute a material default and in
respect of which the Company or such subsidiary has not taken adequate steps to
prevent such a default from occurring) except where the lack of such good
standing, validity and effectiveness or the existence of such default or event
of default would not have a Material Adverse Effect.  All the facilities of the
Company and its subsidiaries, except such as may be under construction, are in
good operating condition and repair, except where the failure of such plants,
structures and equipment to be in such good operating condition and repair would
not, individually or in the aggregate, have a Material Adverse Effect.

          SECTION 2.16.  TAXES.  (a)  For purposes of this Agreement, "Tax" or
"Taxes" shall mean taxes, fees, levies, duties, tariffs, imposts, premiums and
governmental impositions or charges of any kind in the nature of (or similar to)
taxes, payable to any federal, state, provincial, local or foreign taxing
authority, including (without limitation) (i) income, capital, business,
franchise, profits, gross receipts, AD VALOREM, goods and services, customs, net
worth, value added, sales, use, service, real or personal property, special
assessments, capital stock, license, payroll, withholding, employment, social
security, workers' compensation, unemployment insurance or compensation,
utility, severance,


<PAGE>

                                       14

production, excise, stamp, occupation, premiums, windfall profits, transfer and
gains taxes, fees, levies, duties, tariffs, imposts, premiums and governmental
impositions and (ii) interest, penalties, additional taxes and additions to tax
imposed with respect thereto; and "Tax Returns" shall mean returns, reports and
information statements with respect to Taxes required to be filed with Revenue
Canada, the IRS or any other taxing authority, domestic or foreign, including,
without limitation, consolidated, combined and unitary tax returns.

          (b)  The Company and its subsidiaries have filed all Canadian and
United States federal income Tax Returns and all other material Tax Returns
required to be filed by them, and the Company and its subsidiaries have paid and
discharged all Taxes due in connection with or with respect to the filing of all
Tax Returns and have paid all other Taxes as are due, and there are no other
Taxes that would be due if asserted by a taxing authority, except such as are
being contested in good faith by appropriate proceedings (to the extent that any
such proceedings are required) and with respect to which the Company is
maintaining reserves to the extent currently required in all material respects
adequate for their payment except to the extent the failure to do so would not
have a Material Adverse Effect.   Neither Revenue Canada, the IRS nor any other
taxing authority or agency is now asserting or, to the best of the Company's
knowledge, threatening to assert against the Company or any of its subsidiaries
any deficiency or claim for additional Taxes other than additional Taxes with
respect to which the Company is maintaining reserves in all material respects
adequate for their payment, and there are no requests for information currently
outstanding that could affect the Taxes of the Company or any of its
subsidiaries.  Except as disclosed in Section 2.16(b) of the Company Disclosure
Schedule, neither the Company nor any of its subsidiaries is currently being
audited by any taxing authority except as would not have a Material Adverse
Effect.  There are no tax liens on any assets of the Company or any subsidiary
thereof and neither the Company nor any of its subsidiaries has, except as would
not have a Material Adverse Effect, granted any waiver of any statute of
limitations with respect to, or any extension of a period for the assessment of,
any Tax.  The accruals and reserves for Taxes reflected in the 1994 Balance
Sheet are in all material respects adequate to cover all Taxes accruable through
the date thereof (including interest and penalties, if any, thereon and Taxes
being contested) in accordance with generally accepted accounting principles.
Except as disclosed in Section 2.16(b) of the Company Disclosure Schedule,
neither the Company nor any of its subsidiaries is required to include in income
(i) items in respect of any change in accounting principles or deferred
intercompany transactions or (ii) any installment sale gain, where the inclusion
in income would result in a tax liability materially in excess of the reserves
therefor.

          (c)  The Company on behalf of itself and all its subsidiaries hereby
represents that, other than as disclosed on Section 2.16(c) of the Company
Disclosure Schedule, and other than with respect to items the inaccuracy of
which would not have a Material Adverse Effect:  (i) neither the Company nor any
of its subsidiaries is a party to any agreement, contract or arrangement that
may result, separately or in the aggregate, in the


<PAGE>

                                       15

payment of any "excess parachute payment" within the meaning of Section 280G of
the Code, determined without regard to Section 280G(b)(4) of the Code, (ii)
neither the Company or any of its subsidiaries has been subject to any
accumulated earning tax or personal holding company tax, (iii) neither the
Company nor any of its subsidiaries owns stock in a passive foreign investment
company within the meaning of Section 1296 of the Code, and (iv) neither the
Company nor any of its subsidiaries is obligated under any agreement with
respect to industrial development bonds or other obligations with respect to
which the excludability from gross income of the holder for United States
federal or state income tax purposes could be affected by the transactions
contemplated hereunder.

          (d)  No power of attorney has been granted by the Company or any of
its subsidiaries with respect to any matter relating to Taxes which is currently
in force.

          (e)  Neither the Company nor any of its subsidiaries is a party to any
agreement or arrangement (written or oral) providing for the allocation or
sharing of Taxes.

          (f)  The Company and each of its subsidiaries have withheld all
material amounts from each payment made to any of their respective past or
present employees, officers or directors the amount of all Taxes and other
material deductions required to be withheld therefrom and have paid the same to
the proper tax or other receiving officers within the time required under any
applicable legislation.

          (g)  The Company has remitted to the appropriate tax authority when
required by law to do so all amounts collected by it on account of all GST and
retail sales tax.

          (h)  The Company has withheld from each payment made to any employee
or non-resident of Canada the amount of all material Taxes, contributions,
premiums and other deductions required to be withheld therefrom and has paid the
same to the proper tax or other receiving officers within the time required
under any applicable legislation.

          (i)  The Company has not deducted any material amounts in computing
its income in a taxation year which will be included in a subsequent taxation
year under section 78 of the Income Tax Act (Canada).

          (j)  All of the subsidiaries of the Company have taxation years ending
on January 31 of each year except for the U.S. and Italian subsidiaries of the
Company, the taxation years of which each end on December 31 of each year.

          SECTION 2.17.  ENVIRONMENTAL MATTERS.  Except in all cases as have not
had and could not reasonably be expected to have a Material Adverse Effect, the
Company and each of its subsidiaries to the best of the Company's knowledge
(i) have obtained all

                                       16

applicable permits, licenses and other authorization which are required under
federal, state, provincial or local laws relating to pollution or protection of

threatened releases of pollutants, contaminants or hazardous or toxic materials
or wastes into ambient air, surface water, ground water or land or otherwise
relating to the manufacture, processing, distribution, use, treatment, storage,
disposal, transport or handling of pollutants, contaminants or hazardous or
toxic materials or wastes by the Company or its subsidiaries (or their
respective agents); (ii) are in compliance with all terms and conditions of such
required permits, licenses and authorization, and also are in compliance with
all other limitations, restrictions, conditions, standards, prohibitions,
requirements, obligations, schedules and timetables contained in such laws or
contained in any regulation, code, plan, order, decree, judgment, notice or
demand letter issued, entered, promulgated or approved thereunder; (iii) as of
the date hereof, are not aware of nor have received notice of any event,
condition, circumstance, activity, practice, incident, action or plan which is
reasonably likely to interfere with or prevent continued compliance with or
which would give rise to any common law or statutory liability, or otherwise
form the basis of any claim, action, suit or proceeding, based on or resulting
from the Company's or any of its subsidiary's (or any of their respective
agent's) manufacture, processing, distribution, use, treatment, storage,
disposal, transport or handling, or the emission, discharge or release into the
environment, of any pollutant, contaminant or hazardous or toxic material or
waste; and (iv) have taken all actions reasonably necessary under applicable
requirements of federal, state or local laws, rules or regulations to register
any products or materials required to be registered by the Company or its
subsidiaries (or any of their respective agents) thereunder.

          SECTION 2.18.  BROKERS.  No broker, finder or investment banker (other
than Robertson, Stephens & Company, L.P.) is entitled to any brokerage, finder's
or other fee or commission in connection with the transactions contemplated by
this Agreement based upon arrangements made by or on behalf of the Company.  The
Company has heretofore furnished to Parent a complete and correct copy of all
agreements between the Company and Robertson, Stephens & Company, L.P. pursuant
to which such firm would be entitled to any payment relating to the transactions
contemplated hereunder.

          SECTION 2.19.  FULL DISCLOSURE.  No statement contained in any
certificate or schedule furnished or to be furnished by the Company or any of
its subsidiaries to Parent or Amalgamation Sub in, or pursuant to the provisions
of, this Agreement contains or shall contain any untrue statement of a material
fact or omits or will omit to state any material fact necessary, in the light of
the circumstances under which it was made, in order to make the statements
herein or therein not misleading.

          SECTION 2.20.  INTELLECTUAL PROPERTY.  (a)  The Company owns, or is
licensed or otherwise possesses legally enforceable rights to use, all patents,
trademarks, trade names, service marks, copyrights and any applications

computer software programs or applications (in both source code and object code
form) and tangible or intangible proprietary information or material that are
used or proposed to be used in the business of the Company as currently

and past (lapsed, expired, abandoned or canceled) patents, registered and
material unregistered trademarks and service marks, registered and material

2.20(b) of the Company Disclosure Schedule includes and specifically identifies
all third-party patents, trademarks or copyrights (including software) (the

subject matter thereof, the applicable royalty and the term thereof.

         (b)  The Company is not, nor will it be as a result of the execution
and delivery of this Agreement or the performance of its obligations hereunder,
in violation in any material respect of any license, sublicense or agreement
described in Section 2.20(a) of the Company Disclosure Schedule.  No claims with
respect to the Company Intellectual Property Rights, any trade secret material

arising out of any use, reproduction or distribution of such Third Party
Intellectual Property Rights by or through the Company, are currently pending
or, to the knowledge of the Company, are threatened by any person, nor does the
Company know of any valid grounds for any bona fide claims (i) to the effect
that the manufacture, sale, licensing or use of any product as now used, sold or
licensed or proposed for use, sale or license by the Company infringes on any
copyright, patent, trademark, service mark or


<PAGE>

                                       18

and which has not been finally terminated prior to the date hereof, or been
informed or notified by any third party that the Company may be engaged in such
infringement, or (ii) has knowledge of any infringement liability with respect
to, or infringement by, the Company or any of its subsidiaries of any trade

as to which coverage has been questioned, denied or disputed by the underwriters
of such policies or bonds.  All premiums payable under all such policies and
bonds have been paid and the Company and its subsidiaries are otherwise in
compliance in all material respects with the terms of such policies and bonds
(or other policies and bonds providing substantially similar insurance
coverage).  Such policies of insurance and bonds are of the type and in amounts

threatened termination of, or material premium increase with respect to, any of
such policies.

          SECTION 2.23.  OPTION PLANS.  Except as set forth in Section 2.23 of
the Company Disclosure Schedule, the Board of Directors of the Company has taken

affiliates) would affect the ability of Parent to account for the business
combination to be effected by the Arrangement as a pooling of interests.

          SECTION 2.26.  OPINION OF FINANCIAL ADVISOR.  The Company has been
advised by its financial advisor, Robertson, Stephens & Company, L.P., that in

                                   ARTICLE III

              REPRESENTATIONS AND WARRANTIES OF PARENT, SWISSCO AND
                                AMALGAMATION SUB

          Parent, Swissco, and Amalgamation Sub hereby, jointly and severally,
represent and warrant to the Company that:

          SECTION 3.01.  ORGANIZATION AND QUALIFICATION.   Each of Parent and
each of its subsidiaries is a corporation duly organized, validly existing and
in good standing under the laws of the jurisdiction of its incorporation and has
the requisite corporate power and authority and is in possession of all
Approvals necessary to own, lease and operate the


<PAGE>

                                       20

properties it purports to own, operate or lease and to carry on its business as
it is now being conducted, except where the failure to be so organized, existing
and in good standing or to have such power, authority and Approvals would not
have a Material Adverse Effect. Each of Parent and each of its subsidiaries is
duly qualified or licensed as a foreign corporation to do business, and is in
good standing, in each jurisdiction where the character of its properties owned,
leased or operated by it or the nature of its activities makes such
qualification or licensing necessary, except for such failures to be so duly
qualified or licensed and in good standing that would not have a Material

properties or assets of Parent or any of it subsidiaries pursuant to, any
material note, bond, mortgage, indenture, contract, agreement, lease, license,
permit, franchise or other instrument or obligation to which Parent or any of
its subsidiaries is a party or by which Parent or any of its subsidiaries or its

case for any such breaches, defaults or other occurrences that would not have a
Material Adverse Effect.

          (c)  The execution and delivery of this Agreement and the Ancillary
Documents (as defined in Section 5.16 hereof) by Parent, Swissco and

the Blue Sky Laws, the pre-merger notification requirements of the HSR Act, the
OSA and other relevant Canadian Securities statutes, filing with the agency

authorizations or permits, or to make such filings or notifications, would not
prevent or delay consummation of the Arrangement, or otherwise prevent Parent or
Amalgamation Sub from performing their respective obligations under this
Agreement and the Ancillary Documents, and would not have a Material Adverse
Effect.

          SECTION 3.04.  CERTIFICATE OF INCORPORATION AND BY-LAWS.  Parent has
heretofore furnished to the Company a complete and correct copy of its
Certificate of Incorporation and the By-Laws, as amended to date.  Such

Parent, Swissco nor Amalgamation Sub is in violation of any of the provisions of
its Certificate of Incorporation or By-Laws.

          SECTION 3.05.  CAPITALIZATION.  As of January 31, 1995, the authorized

          SECTION 3.06.  COMPLIANCE; PERMITS.  (a)  Neither Parent, nor any of
its subsidiaries is in conflict with, or in default or violation of, (i) any
law, rule, regulation, order, judgment or decree applicable to Parent or any of
its subsidiaries or by which its or any of their respective properties is bound
or affected or (ii) any note, bond, mortgage, indenture, contract, agreement,
lease, license, permit, franchise or other instrument or obligation to which

Material Adverse Effect.

easements, variances, exemptions, consents, certificates, orders and approvals
from governmental or other regulatory authorities which are material to the
operation of the business of the Company and its subsidiaries taken as a whole
as it is now being conducted (collectively, the "Parent Permits").  Parent and
its subsidiaries are in compliance with the terms of Parent Permits, except
where the failure to so comply would not have a Material Adverse Effect.

filed all forms, reports and documents required to be filed with the SEC since
June 30, 1992, and has heretofore delivered to the Company, in the form filed

amendments and supplements to all such reports and registration statements filed
by Parent with the SEC (collectively, the "Parent SEC Reports").  The Parent SEC
Reports (i) were prepared in accordance with the requirements of the Securities
Act or the Exchange Act, as the case may be, and (ii) did not at the time they
were filed (or if amended or superseded by a filing prior to the date of this
Agreement, then on the date of such filing) contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.  None of Parent's
subsidiaries is required to file any forms, reports or other documents with the
SEC.

          (b)  Each of the consolidated financial statements (including, in each
case, any related notes thereto) contained in the Parent SEC Reports has been

<PAGE>

                                       23

accordance with GAAP applied on a consistent basis throughout the
periods involved (except as may be indicated in the notes thereto) and each
fairly presents the consolidated financial position of Parent and its
subsidiaries as at the respective dates thereof and the consolidated results of
its operations and cash flows for the periods indicated, except that the
unaudited interim financial statements were or are subject to normal and
recurring year-end adjustments which were not or are not expected to be material
in amount.

          (c)  Parent has heretofore furnished to the Company a complete and
correct copy of any amendments or modifications, which have not yet been filed
with the SEC but which are required to be filed, to agreements, documents or
other instruments which previously had been filed by Parent with the SEC

          SECTION 3.08.  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as set
forth on Section 3.08 of the Parent Disclosure Schedule, since June 30, 1994,
Parent has conducted its business in the ordinary course and there has not
occurred:  (i) any Material Adverse Effect; (ii) any amendments or changes in
the Certificate of Incorporation or Bylaws of Parent; (iii) any damage to,
destruction or loss of any assets of the Parent, (whether or not covered by
insurance) that could have a Material Adverse Effect; (iv) any revaluation by
Parent of any of its assets, including without limitation, writing down the
value of capitalized software or inventory or writing off notes or accounts
receivable other than in the ordinary course of business, or (v) except as
disclosed in Section 3.08 of the Parent Disclosure Schedule, any other action or
event that would have required the consent of the Company pursuant to Section
4.03 had such action or event occurred after the date of this Agreement.

          SECTION 3.09.  RESTRICTIONS ON BUSINESS ACTIVITIES.  Except for this
Agreement, there is no material agreement, judgment, injunction, order or decree
binding upon Parent or any of its subsidiaries which has or could reasonably be
expected to have the effect of prohibiting or materially impairing any business
practice of Parent or any of its subsidiaries, any acquisition of property by
Parent or any of its subsidiaries or the conduct of business by Parent or any of
its subsidiaries as currently conducted or as proposed to be conducted by
Parent.

          SECTION 3.10.  TITLE TO PROPERTY.  Parent and each of its subsidiaries
have good, marketable and defensible title to all of their properties and
assets, free and clear of all liens, charges and encumbrances except liens for
taxes not yet due and payable and such liens or other imperfections of title, if
any, as do not materially detract from the value of or interfere with the
present use of the property affected thereby or which would not have a Material
Adverse Effect; and, to Parent's knowledge, all leases pursuant to which Parent
or any of its subsidiaries lease from others material amounts of real or
personal property are in good standing, valid and effective in accordance with
their respective terms, and there is not, to the knowledge of Parent, under any
of such leases, any existing material default or event


<PAGE>

                                       24

of default (or event which with notice or lapse of time, or both, would
constitute a material default and in respect of which Parent or such subsidiary
has not taken adequate steps to prevent such a default from occurring) except
where the lack of such good standing, validity and effectiveness, or the
existence of such default or event of default would not have a Material Adverse
Effect.

          SECTION 3.11.  FULL DISCLOSURE.  No statement contained in any
certificate or schedule furnished or to be furnished by Parent, Swissco or
Amalgamation Sub to the Company in, or pursuant to the provisions of, this
Agreement contains or will contain any untrue statement of a material fact or
omits or shall omit to state any material fact necessary, in the light of the
circumstances under which it was made, in order to make the statements herein or
therein not misleading.

          SECTION 3.12.  NO UNDISCLOSED LIABILITIES.  Except as is disclosed in
Section 3.12 of the Parent Disclosure Schedule or the Parent SEC Reports,
neither the Parent nor any of its subsidiaries has any liabilities (absolute,
accrued, contingent or otherwise) which are, in the aggregate, material to the
business, operations or financial condition of the Parent and its subsidiaries
taken as a whole, except liabilities (a) adequately provided for in the Parent's
balance sheet (including any related notes thereto) as of June 30, 1994 included
in the Parent SEC Reports (the "June 30 Balance Sheet"), (b) incurred in the
ordinary course of business and not required under GAAP to be reflected on the
June 30 Balance Sheet, or (c) incurred since June 30, 1994 in the ordinary
course of business and consistent with past practice, and liabilities incurred
in connection with this Agreement.

          SECTION 3.13.  ABSENCE OF LITIGATION.  Except as set forth in Section
3.13 of the Parent Disclosure Schedule or as reflected in the Parent SEC
Reports, there are no claims, actions, suits, proceedings or investigations
pending or, to the knowledge of the Parent, threatened against the Parent or any
of its subsidiaries, or any properties or rights of the Parent or any of its
subsidiaries, before any court, arbitrator or administrative, governmental or
regulatory authority or body, domestic or foreign, that could have a Material
Adverse Effect.

          SECTION 3.14.  INSURANCE.  Parent and its subsidiaries maintain fire
and casualty, general liability, business interruption, product liability and
sprinkler and water damage insurance that Parent believes to be reasonably
prudent for its business.

          SECTION 3.15.  REGISTRATION STATEMENT; PROXY STATEMENT/PROSPECTUS.
Subject to the accuracy of the representations of the Company in Section 2.13
hereof, the Registration Statement, if any, pursuant to which the Parent Common
Shares to be issued in the Arrangement will be registered with the SEC shall
not, at the time the Registration Statement (including any amendments or
supplements thereto) is declared effective by the SEC, contain any untrue
statement of a material fact or omit to state any material fact



<PAGE>

                                       25

necessary in order to make the statements included therein, in light of the
circumstances under which they were made, not misleading. Subject to the
accuracy of the representations of the Company in Section 2.13, the information
supplied by Parent for inclusion in the Proxy Statement/Prospectus will not, on
the date the Proxy Statement/Prospectus is first mailed to stockholders, at the
time of the Company Stockholders' Meeting and at the Effective Date, contain any
statement which, at such time and in light of the circumstances under which it
shall be made, is false or misleading with respect to any material fact, or will
omit to state any material fact necessary in order to make the statements
therein not false or misleading. If at any time prior to the Effective Date any
event relating to Parent, Swissco, Amalgamation Sub or any of their respective
affiliates, officers or directors should be discovered by Parent, Swissco or
Amalgamation Sub which should be set forth in an amendment to the Registration
Statement, if any, or a supplement to the Proxy Statement/Prospectus, Parent,
Swissco or Amalgamation Sub will promptly inform the Company. Notwithstanding
the foregoing, Parent makes no representation or warranty with respect to any
information supplied by the Company which is contained in, or furnished in
connection with the preparation of, any of the foregoing.

        (b)  As of the date hereof and the Effective Date, except for
obligations or liabilities incurred in connection with its incorporation or
organization and the transactions contemplated by this Agreement and except for
this Agreement and any other agreements or arrangements contemplated by this
Agreement, Amalgamation Sub has not and will not have incurred, directly or
indirectly, through any subsidiary or affiliate, any obligations or liabilities
or engaged in any business activities of any type or kind whatsoever or entered
into any agreements or arrangements with any person.

          SECTION 3.16.  TAXES.  Other than as disclosed on Section 3.16 of the
Parent Disclosure Schedule, the Parent and each of its subsidiaries, and any
consolidated, combined, unitary or aggregate group for Tax purposes of which
Parent or any of its subsidiaries is or has been a member, have filed all United
States federal income Tax Returns and all other material Tax Returns required to
be filed by them or any of them, and have paid and discharged all Taxes shown
therein to be due and there are no other Taxes that would be due if asserted by
a taxing authority, except such as are being contested in good faith by
appropriate proceedings (to the extent that any such proceedings are required)
or with respect to which Parent is maintaining reserves in accordance with GAAP
in its financial statements to the extent currently required in all material
respects adequate for their payment, except, in each instance, to the extent the
failure to do so would not have a Material Adverse Effect.   Neither the IRS nor
any other taxing authority or agency is now asserting or, to the best of
Parent's knowledge, threatening to assert against Parent or any of its
subsidiaries any deficiency or claim for additional Taxes other than additional
Taxes with respect to which the Parent is maintaining reserves in accordance
with GAAP in its financial statements which are in all material respects
adequate for their payment.   Other than as disclosed on Section 3.16 of the
Parent Disclosure Schedule, no Tax Return of either Parent or any of its
subsidiaries


<PAGE>

                                       26

is currently being audited by any taxing authority except as would not have a
Material Adverse Effect.   Other than as disclosed on Section 3.16 of the Parent
Disclosure Schedule, no material tax claim has become a lien on any assets of
the Parent or any subsidiary thereof and neither Parent nor any of its
subsidiaries has, except as would not have a Material Adverse Effect, granted
any waiver of any statute of limitations with respect to, or any extension of a
period for the assessment of, any Tax.

          SECTION 3.17.  BROKERS.  No broker, finder or investment banker (other
than Morgan Stanley & Co. Incorporated and Unterberg Harris, L.P.) is entitled
to any brokerage, finder's or other fee or commission in connection with the
transactions contemplated by this Agreement based upon arrangements made by or
on behalf of Parent, Swissco or Amalgamation Sub.

          SECTION 3.18.  OPINION OF FINANCIAL ADVISOR.  Parent has been advised
by its financial advisor, Morgan Stanley & Co. Incorporated, that in its
opinion, as of the date hereof, the Exchange Ratio is fair from a financial
point of view to Parent, and has delivered a copy of such opinion to the
Company.

          SECTION 3.19.  POOLING MATTERS.  Neither Parent nor any of its
affiliates has, to its knowledge and based upon consultation with its
independent accountants, taken or agreed to take any action that (without giving
effect to any action taken or agreed to be taken by the Company or any of its
affiliates) would affect the ability of Parent to account for the business
combination to be effected by the Arrangement as a pooling of interests.

          SECTION 3.20.  NO STOCKHOLDER VOTE.  No vote of the stockholders of
Parent or Swissco is necessary to approve the Arrangement or the issuance of
Parent Common Shares pursuant thereto.

                                   ARTICLE IV

                   CONDUCT OF BUSINESS PENDING THE ARRANGEMENT

ARRANGEMENT.  During the period from the date of this Agreement and continuing
until the earlier of the termination of this Agreement or the Effective Date,
the Company covenants and agrees that, unless Parent shall otherwise agree in
writing, the Company shall conduct its business and shall cause the businesses
of its subsidiaries to be conducted only in, and the Company and its
subsidiaries shall not take any action except in, the ordinary course of
business or in accordance with the provisions of this Agreement and in a manner
consistent with past practice; and the Company shall use reasonable commercial
efforts to preserve substantially intact the business organization of the
Company and its subsidiaries, to keep available the services of the present
officers, employees and consultants of the Company and


<PAGE>

                                       27

its subsidiaries, to take all action reasonably necessary to prevent the loss,
cancellation, abandonment, forfeiture or expiration of any Company Intellectual
Property and to preserve the present relationships of the Company and its
subsidiaries with customers, suppliers and other persons with which the Company
or any of its subsidiaries has significant business relations; PROVIDED,
HOWEVER, that the provisions of this Section 4.01 shall not prevent the Company
from taking action to cause the Exchangeable Shares and/or the Shares to be
listed, posted or quoted for trading on a Canadian stock exchange. By way of
amplification and not limitation, except as contemplated by this Agreement,
neither the Company nor any of its subsidiaries shall, during the period from
the date of this Agreement and continuing until the earlier of the termination
of this Agreement or the Effective Date, directly or indirectly do, or agree to
do, any of the following without the prior written consent of Parent:

     code licenses in the ordinary course of business consistent with past
     practice;

          (g)  (i) acquire (by merger, consolidation, or acquisition of stock or

     set forth herein not being satisfied.

          SECTION 4.02.  NO SOLICITATION.  (a)  The Company shall not, directly

prevent the Board of Directors of the Company from referring any third party to
this Section 4.02(a) or providing such party with a copy of this Section
4.02(a).  Nothing contained in this Section 4.02(a) or other provision of this
Agreement shall prevent the Board of Directors of the Company from considering,
negotiating, approving and recommending to the stockholders of the Company an
unsolicited bona fide written Acquisition Proposal which the Board of Directors
of the Company determines in good faith (after consultation with its financial
advisors, and after receiving a


<PAGE>

                                       30

written opinion of outside counsel, or advice of outside counsel that is
reflected in the minutes of the Board of Directors of the Company, to the effect
that the Board of Directors is required to do so in order to discharge properly
its fiduciary duties) would, if consummated in accordance with its terms, result
in a transaction more favorable to the Company's stockholders than the
transaction contemplated by this Agreement (any such Acquisition Proposal being
referred to herein as a "SUPERIOR PROPOSAL").

          (b)  The Company shall immediately notify Parent after receipt of any
written Acquisition Proposal or any request for nonpublic information relating
to the Company or any of its subsidiaries in connection with an Acquisition
Proposal or for access to the properties, books or records of the Company or any
subsidiary by any person or entity that informs the Board of Directors of the
Company or such subsidiary that it is considering making, or has made, an
Acquisition Proposal.  Such notice to Parent shall be made orally and in writing
and shall indicate in reasonable detail the terms and conditions of such
proposal, inquiry or contact.

          (c)  If the Board of Directors of the Company receives a request for
material nonpublic information by a party who makes a bona fide Acquisition
Proposal and the Board of Directors of the Company determines that such proposal
is a Superior Proposal, then, and only in such case, the Company may, subject to
the execution of a confidentiality  agreement substantially similar to that then
in effect between the Company and Parent, provide such party with access to
information regarding the Company.

          (d)  The Company shall immediately cease and cause to be terminated
any existing discussions or negotiations with any parties (other than Parent and
Amalgamation Sub) conducted heretofore with respect to any of the foregoing.
The Company agrees not to release any third party from any confidentiality or
standstill agreement to which the Company is a party.

          (e)  The Company shall ensure that the officers, directors and
employees of the Company and its subsidiaries and any investment bankers or
other advisors or representatives retained by the Company are aware of the
restrictions described in this Section, and shall be responsible for any breach
of this Section 4.02 by such bankers, advisors or representatives.

          SECTION 4.03.  CONDUCT OF BUSINESS BY PARENT PENDING THE ARRANGEMENT.
During the period from the date of this Agreement and continuing until the
earlier of the termination of this Agreement or the Effective Date, Parent
covenants and agrees that, unless the Company shall otherwise agree in writing,
Parent shall conduct its business, and cause the businesses of its subsidiaries
to be conducted, in the ordinary course of business and consistent with past
practice, other than actions taken by Parent or its subsidiaries in


<PAGE>

                                       31

contemplation of the Arrangement and the Other Merger, and shall not directly or
indirectly do, or propose to do, any of the following without the prior written
consent of the Company:

          (a)  amend or otherwise change Parent's Articles of Incorporation, or
     amend the terms of the Parent Common Stock, except for the filing of the
     certificate of designation referred to in Section 5.16 hereof;

          (b)  except for the Other Merger, acquire or agree to acquire, by
     merging or consolidating with, by purchasing an equity interest in or a
     portion of the assets of, or by any other manner, any business or any
     corporation, partnership, association or other business organization or
     division thereof, or otherwise acquire or agree to acquire any assets of
     any other person, which, in each case, would materially delay or prevent
     the consummation of the transactions contemplated by this Agreement;

          (c)  declare, set aside, make or pay any dividend or other
     distribution (whether in cash, stock or property or any combination
     thereof) in respect of any of its capital stock, except that a wholly owned
     subsidiary of Parent may declare and pay a dividend to its parent;

          (d)  sell, transfer, license, sublicense or otherwise dispose of any
     material assets; or

          (e)  take or agree in writing or otherwise to take any action which
     would make any of the representations or warranties of Parent, Swissco or
     Amalgamation Sub contained in this Agreement untrue or incorrect or prevent
     Parent, Swissco or Amalgamation Sub from performing or cause Parent,
     Swissco or Amalgamation Sub not to perform its respective covenants
     hereunder.

                              ADDITIONAL AGREEMENTS

          SECTION 5.01.  PROXY STATEMENT/PROSPECTUS; REGISTRATION STATEMENT.
(a)  As promptly as practicable after the execution of this Agreement, the
Company and Parent shall, if so required, prepare and file with the SEC
preliminary proxy materials which shall constitute the Proxy Statement of the
Company and the Registration Statement and/or offering circular of the Parent
with respect to the Parent Common Shares to be issued in connection with the
Arrangement.  As promptly as practicable after comments are received from the
SEC thereon and after the furnishing by the Company and Parent of all
information required to be contained therein, the Company and Parent shall file
with the SEC a combined proxy and registration statement and/or offering
circular on Form S-4 (or on such other form


<PAGE>

                                       32

as shall be appropriate) relating to the approval of the Arrangement and the
transactions contemplated hereby by the stockholders of the Company and shall
use all reasonable efforts to cause the Registration Statement to become
effective as soon thereafter as practicable. The Proxy Statement shall include
the recommendation of the Board of Directors of the Company in favor of the
Arrangement, subject to the second sentence of Section 4.02(a). Notwithstanding
anything herein to the contrary, Parent shall be under no obligation to file the
Registration Statement if it shall have determined on the advice of outside
counsel that the issuance of the Exchangeable Shares, Parent Common Stock and
preferred stock covered by the certificate of designation referred to in Section
5.16 hereof are exempt from the registration requirements of Section 5 of the
Securities Act by virtue of Section 3(a)(10) hereof.

         (b)  As promptly as practicable after the execution of this Agreement,
the Company agrees that it will apply to the Ontario Court of Justice (General
Division) (the "Court") pursuant to Section 182 of the OBCA for an interim order
in form and substance satisfactory to Parent (such approval not to be
unreasonably withheld or delayed) (the "Interim Order") providing for, among
other things, the calling and holding of the Company Stockholders' Meeting for
the purpose of considering and, if deemed advisable, approving the Arrangement
under Section 182 of the OBCA.  If the approval by the shareholders of the
Company of the Arrangement is obtained, thereafter the Company will take the
necessary steps to submit the Arrangement to the Court and apply for a final
order of the Court approving such Arrangement in such fashion as the Court may
direct.

          SECTION 5.02.  STOCKHOLDERS' MEETING.  The Company shall call and hold
the Company Stockholders' Meeting as promptly as practicable for the purpose of
voting upon the approval of the Arrangement.  The Company shall use its
reasonable best efforts to hold the Company Stockholders' Meeting as soon as
practicable after the later of the dates on which the Registration Statement, if
any, becomes effective and the Interim order is granted.  Subject to the second
sentence of Section 4.02(a), the Company shall use its reasonable best efforts
to solicit from its stockholders proxies in favor of the approval of the
Arrangement, and to take all other action as may be reasonably necessary or
advisable to secure the vote or consent of stockholders required by the OBCA or
the OSA to obtain such approvals.

          SECTION 5.03.  ACCESS TO INFORMATION; CONFIDENTIALITY.  Upon
reasonable notice and subject to restrictions contained in confidentiality
agreements to which such party is subject, the Company and Parent shall each
(and shall cause each of their subsidiaries to) afford to the officers,
employees, accountants, counsel and other representatives of the other,
reasonable access, during the period prior to the Effective Date, to all its
properties, books, contracts, commitments and records and, during such period,
the Company and Parent each shall (and shall cause each of their subsidiaries
to) furnish promptly to the other all information concerning its business,
properties and personnel as such other party may reasonably request, and each
shall make available to the other the appropriate individuals


<PAGE>

                                       33

(including attorneys, accountants and other professionals) for discussion of the
other's business, properties and personnel as either party may reasonably
request. Each party shall keep such information confidential in accordance with
the terms of the existing confidentiality agreement (the "Confidentiality
Agreement") between Parent and the Company.

          SECTION 5.04.  CONSENTS; APPROVALS.  The Company and Parent shall each
use all reasonable efforts to obtain all consents, waivers, approvals,
authorizations or orders (including, without limitation, all United States,
Canadian federal and provincial and foreign governmental and regulatory rulings
and approvals), and the Company and Parent shall make all filings (including,
without limitation, all filings with United States, Canadian federal and
provincial and foreign governmental or regulatory agencies) required in
connection with the authorization, execution and delivery of this Agreement by
the Company, Swissco, Amalgamation Sub and Parent and the consummation by them
of the transactions contemplated hereby.  The Company and Parent (with respect
to themselves and their respective subsidiaries) shall furnish all information
required to be included in the Proxy Statement and the Registration Statement,
or for any application or other filing to be made pursuant to the rules and
regulations of any United States, Canadian federal or provincial or foreign
governmental body in connection with the transactions contemplated by this
Agreement.

          SECTION 5.05.  STOCK OPTIONS.  (a)  On the Effective Date, the
Company's obligations with respect to each outstanding option to purchase shares
of Company Common Stock (each a "Company Option") under the Company's 1988
Employee Share Ownership Plan, 1989 Employee Share Ownership Plan, 1990 Employee
Share Ownership Plan and 1994 Stock Plan (individually, a "Company Stock Option
Plan," and, collectively, the "Company Stock Option Plans"), whether vested or
unvested, will be assumed by Parent and, on such assumption, the rights to
acquire Company Common Shares under the Common Stock Option Plans shall be
exchanged for rights to acquire Parent Common Shares under such plans.  Each
Company Option so assumed by Parent under this Agreement shall continue to have,
and be subject to, the same terms and conditions set forth in the Company Stock
Option Plan and agreement pursuant to which such Company Option was issued as in
effect immediately prior to the Effective Date, except that (i) such Company
Option will be deemed to constitute an option to purchase that number of Parent
Common Shares equal to the product of the number of shares of Company Common
Stock that the holder of such option would have been entitled to receive
pursuant to the Arrangement had such holder exercised such options immediately
prior to the Effective Date (not taking into account whether such option was in
fact exercisable) multiplied by the Exchange Ratio, rounded up to the nearest
whole number of shares of Parent Common Shares, and (ii) the per share exercise
price for the shares of Parent Common Stock issuable upon exercise of such
assumed Company Option will be equal to the quotient determined by dividing the
exercise price per share of Company Common Stock at which such Company Option
was exercisable


<PAGE>

                                       34

immediately prior to the Effective Date by the Exchange Ratio, and rounding the
resulting exercise price up to the nearest whole cent.

          (b)  It is the intention of the parties that the Company Options
assumed by Parent qualify following the Effective Date as incentive stock
options as defined in the Code ("ISO's"), to the extent the Company Options
qualified as ISO's prior to the Effective Date.

          (c)  The Company shall ensure that any required consents of holders of
such options or rights to such assumptions are obtained prior to the Effective
Date.

          (d)  As soon as practicable after the Effective Date, Parent shall
deliver to each holder of an outstanding Company Option, an appropriate notice
setting forth such holder's rights pursuant thereto and such Company Option
shall continue in effect on the same terms and conditions (including further
anti-dilution provisions, and subject to the adjustments required by this
Section 5.05 after giving effect to the Arrangement).  Parent shall comply with
the terms of all such Company Options.  Parent shall take all corporate action
necessary to reserve for issuance a sufficient number of Parent Common Shares
for delivery pursuant to the terms set forth in this Section 5.05.

          (e)  Parent shall file and cause to become effective not later than
the Effective Date a registration statement under the Securities Act of 1933
with respect to the assumption by Parent of the Company Options referred to in
Section 5.05 and with respect to the issuance of Parent Common Shares upon
exercise of those options and to keep such registration statement effective
throughout the term of such options.

          SECTION 5.06.  COMPANY EMPLOYEE STOCK PURCHASE PLAN.  (a)  The Company
shall take such actions as are necessary to cause the "purchase date" (as such
term is used in the Company's 1993 Employee Stock Purchase Plan (the "Company
Stock Purchase Plan")) applicable to the then current offering period (as such
term is used in the Company Stock Purchase Plan) to be the last trading day on
which the Parent Common Shares are traded on the New York Stock Exchange
immediately prior to the Effective Date (the "Final Company Purchase Date");
PROVIDED, THAT, such change in the Purchase Date shall be conditioned upon the
consummation of the Arrangement.  On the Final Company Purchase Date, the
Company shall apply the funds credited as of such date under the Company Stock
Purchase Plan within each participant's payroll withholdings account to the
purchase of whole shares of Company Common Stock in accordance with the terms of
the Company Stock Purchase Plan.  The cost to each participant in the Company
Stock Purchase Plan for shares of Company Common Stock shall be the lower of 85%
of the closing sale price of Company Common Stock on the Nasdaq National Market
on (i) the first day of the then current offering period or (ii) the last
trading day on or prior to the Final Company Purchase Date.


<PAGE>

                                       35

          (b)  Employees of the Company as of the Effective Date shall be
permitted to participate in Parent's Employee Stock Purchase Plan commencing on
the first enrollment date following the Effective Date, subject to compliance
with the eligibility provisions of such plan (with employees receiving credit,
for purposes of such eligibility provisions, for service with the Company).

          SECTION 5.07.  AGREEMENTS OF AFFILIATES.  The Company shall deliver to
Parent, prior to the date the Registration Statement becomes effective under the
Securities Act, a letter (the "Affiliate Letter") identifying all persons who
are, or may be deemed to be, at the time of the Company Stockholders' Meetings,
"affiliates" of the Company for purposes of Rule 145 under the Securities Act.
The Company shall use its best efforts to cause each person who is identified as
an "affiliate" in the Affiliate Letter to deliver to Parent, prior to the
Effective Date, a written agreement (an "Affiliate Agreement") in substantially
the form of Exhibit B hereto.

          SECTION 5.08.  INDEMNIFICATION AND INSURANCE.  (a)  The Articles of
Incorporation of the Continuing Corporation shall contain the provisions with
respect to indemnification set forth in the By-Laws of the Company, which
provisions shall not be amended, repealed or otherwise modified for a period of
six years from the Effective Date in any manner that would adversely affect the
rights thereunder of individuals who at the Effective Date were directors,
officers, employees or agents of the Company, unless such modification is
required by law.

          (b)  The Company shall, to the fullest extent permitted under
applicable law or under the Company's Articles of Incorporation or By-Laws and
regardless of whether the Arrangement becomes effective, indemnify and hold
harmless, and after the Effective Date, the Continuing Corporation and Parent
shall, to the fullest extent permitted under applicable law or under the
Continuing Corporation's and Parent's, as the case may be, Articles of
Incorporation or By-Laws, indemnify and hold harmless, each present and former
director, officer, employee, fiduciary and agent of the Company or any of its
subsidiaries (collectively, the "Indemnified Parties") against any costs or
expenses (including attorneys' fees), judgments, fines, losses, claims, damages,
liabilities and amounts paid in settlement in connection with any claim, action,
suit, proceeding or investigation, whether civil, criminal, administrative or
investigative, arising out of or pertaining to any action or omission occurring
at or prior to the Effective Date (including, without limitation, the
transactions contemplated by this Agreement) for a period of six years after the
Effective Date; PROVIDED, HOWEVER, that in the event that any claim or claims
for indemnification are asserted or made within such six-year period, all rights
to indemnification in respect of any such claim or claims shall continue until
the disposition of any and all such claims.  The Indemnified Parties as a group
may retain only one law firm to represent them with respect to any single action
unless there is, under applicable standards of professional conduct, a conflict
on any significant issue between the positions of any two or more Indemnified
Parties.  Any counsel


<PAGE>

                                       36

retained by the Indemnified Parties shall be reasonably satisfactory to Parent
and Parent shall not be liable for any settlement effected without its written
consent (which consent shall not be unreasonably withheld).

          SECTION 5.09.  NOTIFICATION OF CERTAIN MATTERS.  The Company shall
give prompt notice to Parent (in the case of subclauses (i) and (ii)), and
Parent shall give prompt notice to the Company, of (i) the occurrence, or non-
occurrence, of any event the occurrence, or non-occurrence, of which would be
likely to cause any representation or warranty contained in this Agreement to be
untrue or inaccurate, (ii) any failure of the Company, Parent, Swissco or
Amalgamation Sub, as the case may be, materially to comply with or satisfy any
covenant, condition or agreement to be complied with or satisfied by it
hereunder and (iii) any termination of the Other Merger Agreement; PROVIDED,
HOWEVER, that the delivery of any notice pursuant to this Section shall not
limit or otherwise affect the remedies available hereunder to the party
receiving such notice; and PROVIDED, FURTHER, that failure to give such notice
shall not be treated as a breach of covenant for the purposes of Sections
6.02(a) or 6.03(a) unless the failure to give such notice results in material
prejudice to the other party.

          SECTION 5.10.  FURTHER ACTION.  Upon the terms and subject to the
conditions hereof, each of the parties hereto shall use all reasonable efforts
to take, or cause to be taken, all actions and to do, or cause to be done, all
other things necessary, proper or advisable to consummate and make effective as
promptly as practicable the transactions contemplated by this Agreement, to
obtain in a timely manner all necessary waivers, consents and approvals and to
effect all necessary registrations and filings, and to otherwise satisfy or
cause to be satisfied all conditions precedent to its obligations under this
Agreement.  In addition, the Company and Parent shall provide each other with
such cooperation and information as either of them reasonably may request of the
other in filing any Tax Return, amended Tax Return or claim for refund,
determining a liability for Taxes or a right to a refund of Taxes, participating
in or conducting any audit or other proceeding in respect of Taxes or making
representations to or furnishing information to parties subsequently desiring to
purchase any of the Company Common Stock.  Such cooperation and information
shall include providing copies of relevant Tax Returns or portions thereof,
together with accompanying schedules, related work papers and documents relating
to rulings or other determinations by Tax authorities.  Each of Parent, Swissco,
Amalgamation Sub and the Company shall use its best efforts to cause the
exchanges provided for in the Plan of Arrangement to fail to qualify, will take
any actions (that do not materially adversely affect such party) to cause such
exchanges to fail to qualify, and will not (both before and after consummation
of the Arrangement) take any actions which cause such exchanges to qualify, as a
reorganization under the provisions of Section 368 of the Code.

          SECTION 5.11.  PUBLIC ANNOUNCEMENTS.  Parent (on behalf of itself,
Swissco and Amalgamation Sub) and the Company shall consult with each other
before issuing any


<PAGE>

                                       37

press release or otherwise making any public statements with respect to the
Arrangement or this Agreement and shall not issue any such press release or make
any such public statement without the prior consent of the other party, which
shall not be unreasonably withheld; PROVIDED, HOWEVER, that a party may, without
the prior consent of the other party, issue such press release or make such
public statement as may upon the advice of counsel be required by law, the
National Association of Securities Dealers or the New York Stock Exchange
(the "NYSE") or any other regulatory body to which such party is subject if it
has used all reasonable efforts to consult with the other party as to the timing
and content of such release or statement.

          SECTION 5.12.  LISTING OF PARENT COMMON SHARES.  Parent shall use its
reasonable best efforts to cause the shares of Parent Common Stock to be issued
in the Arrangement (including shares of Parent Common Stock issued as a result
of rights attaching to the Exchangeable Shares) to be approved for listing on
the NYSE.

          SECTION 5.13.  CONVEYANCE TAXES.  Parent and the Company shall
cooperate in the preparation, execution and filing of all returns,
questionnaires, applications or other documents regarding any real property
transfer or gains, sales, use, transfer, value added, stock transfer and stamp
taxes, any transfer, recording, registration and other fees, and any similar
taxes which become payable in connection with the transactions contemplated
hereby that are required or permitted to be filed on or before the Effective
Date.

          SECTION 5.14.  ACCOUNTANTS' LETTERS.  Upon reasonable notice from
Parent, the Company shall use its reasonable efforts to cause KPMG Peat Marwick
Thorne to deliver to Parent a letter covering such matters as are customarily
addressed in accountant's "comfort" letters.

          SECTION 5.15.  POOLING ACCOUNTING TREATMENT.  Each of Parent and the
Company agree not to take any action that would adversely affect the ability of
Parent to treat the Arrangement as a pooling of interests under GAAP.

          SECTION 5.16.  ANCILLARY DOCUMENTS/RESERVATION OF SHARES.  (a)
Provided all other conditions of this Agreement have been satisfied or waived,
the Company and Amalgamation Sub shall, as promptly as practicable thereafter,
jointly file Articles of Arrangement pursuant to Section 182(1) of the OBCA to
give effect to the Plan of Arrangement, such Articles of Arrangement to contain
share conditions for the Continuing Corporation substantially in the form of
those contained in Exhibit A hereto.

          (b)  On the Effective Date:

               (i)  Parent, Swissco and the Continuing Corporation shall execute
                    and deliver a Support Agreement between Parent, Swissco and


<PAGE>


                                       38

                    the Continuing Corporation containing the terms and
                    conditions set forth in Exhibit C hereto (the "Support
                    Agreement"), together with such other terms and conditions
                    as may be agreed to by the parties hereto acting reasonably;

               (ii) Parent, Swissco the Continuing Corporation and a Canadian
                    trust company to be selected by Parent shall execute and
                    deliver a Voting and Exchange Trust Agreement containing the
                    terms and conditions set forth in Exhibit D hereto (the
                    "Voting Trust and Exchange Agreement"), together with such
                    other terms and conditions as may be agreed to by the
                    parties hereto acting reasonably; and

               (iii)Parent shall file with the Secretary of State of the
                    State of Delaware a certificate of designation which
                    shall be in substantially the form set forth in Exhibit
                    E hereto.

On and after the Effective Date, Parent and Swissco shall duly and timely
perform all of their respective obligations expressed in the Plan of
Arrangement.  The Plan of Arrangement and the other documents referred to in
this Section 5.16(b) are referred to herein as the "Ancillary Documents."

          (c)  On or prior to the Effective Date, Parent will reserve for
issuance such number of shares of Parent Common Stock as shall be necessary to
give effect to the exchanges, conversions and assumptions of options
contemplated hereby.  On or prior to the Effective Date, Parent and Swissco
shall enter into a stock purchase agreement pursuant to which Swissco will
purchase from Parent the Parent Common Shares to be delivered pursuant hereto
and the Plan of Arrangement to holders of shares at the Effective Date and from
time to time thereafter upon exercise of the Exchangeable Shares.  Upon request
of Parent prior to submission of the Plan of Arrangement for approval of the
Company's stockholders, the Company agrees that the Plan of Arrangement will be
modified to provide for a special class of preferred shares in the capital of
the Continuing Corporation to be purchased for cash by a person or persons
identified by Parent.  Such shares shall have a liquidation preference equal to
the cash purchase price paid therefor, be subordinated, in all other respects,
to all other classes of capital stock of the Continuing Corporation, be non-
voting and have a cumulative dividend rate.

          SECTION 5.17.  OTHER MERGER.  Parent will not close the Other Merger
unless the Arrangement closes substantially contemporaneously therewith, and
will not increase the Other Exchange Ratio, other than increasing such ratio in
response to an Acquisition Proposal (as defined in the Other Merger Agreement)
with respect to Wavefront, without proportionately increasing the Exchange
Ratio.

                          CONDITIONS TO THE ARRANGEMENT


          SECTION 6.01.  CONDITIONS TO OBLIGATION OF EACH PARTY TO EFFECT THE
ARRANGEMENT.  The respective obligations of each party to effect the Arrangement
shall be subject to the satisfaction at or prior to the Effective Date of the
following conditions:

          (a)  EFFECTIVENESS OF THE REGISTRATION STATEMENT/COURT APPROVAL.  The
     Registration Statement, if any, shall have been declared effective by the
     SEC under the Securities Act and shall cover both the Parent Common Shares
     issued at or immediately after the Effective Date and, if no exemption from
     registration under the Securities Act is available, to be issued upon the
     exchange of Exchangeable Shares.  No stop order suspending the
     effectiveness of the Registration Statement, if any, shall have been issued
     by the SEC and no proceedings for that purpose and no similar proceeding in
     respect of the Proxy Statement shall have been initiated or threatened by
     the SEC or the OSC.  The Court shall have issued its final order approving
     the Arrangement in form and substance satisfactory to Parent and the
     Company (such approvals not to be unreasonably withheld or delayed) and
     reflecting the terms hereof;

          (b)  STOCKHOLDER APPROVAL.  This Agreement and the Arrangement shall
     have been approved and adopted by the affirmative requisite vote of the
     stockholders of the Company;

     the Arrangement under the HSR Act shall have expired or been terminated;

     extensions thereof shall have expired or the parties shall have received an
     Advance Ruling Certificate ("ARC") pursuant to section 102 of the
     Competition Act (Canada) setting out that the Director under such Act is
     satisfied he would not have sufficient grounds on which to apply for an
     order in respect of the Arrangement;

          (e)  NO INJUNCTIONS OR RESTRAINTS; ILLEGALITY.  No temporary
     restraining order, preliminary or permanent injunction or other order
     issued by any court of competent jurisdiction or other legal restraint or

     Arrangement shall be in effect, nor shall any proceeding brought by any
     administrative agency or commission or other


<PAGE>

                                       40

     governmental authority or instrumentality, domestic or foreign, seeking any

               (i)  are ultimately entitled to be paid fair value for their
     Company Common Shares shall be deemed to have transferred such Company
     Common Shares to the Corporation for cancellation on the Effective Date; or

               (ii) are ultimately not entitled, for any reason, to be paid fair

     and shall receive Class A Shares on the basis determined in accordance with
     subsection 2.1(c) and thereafter Parent Common Shares on the basis

but in no case shall the Corporation be required to recognize such holders as

of such holders of Company Common Shares shall be deleted from the registers of
holders of Company Common Shares on the Effective Date.

          (b)  The Corporation shall give Parent (i) prompt notice of any
written demand of a right of dissent, withdrawals of such demands, and any other
instruments served pursuant to the OBCA and received by the Corporation and (ii)
the opportunity to participate in all negotiations and proceedings with respect

all payments to be made by the Corporation pursuant to the exercise of such
dissenters' rights shall be advanced or contributed by Parent to the Corporation
in such manner as Parent may determine.

                  ARTICLE 4--CERTIFICATES AND FRACTIONAL SHARES

     4.1  ISSUANCE OF CERTIFICATES REPRESENTING EXCHANGEABLE SHARES

          On or promptly after the Effective Date, the Corporation shall deposit
with the Depositary, for the benefit of the holders of Class B Shares converted
pursuant to subsection 2.1(e), certificates representing the Exchangeable
Shares issued pursuant to subsection 2.1(e) upon the conversion of outstanding
Class B Shares.  Upon surrender to the Depositary for cancellation of a
certificate which immediately prior to the Effective Date represented
outstanding Company Common Shares that were converted into Class B Shares on the
Amalgamation and thereafter converted into Exchangeable Shares, together with
such other documents and instruments as would have been required to effect the
transfer of the shares formerly represented by such certificate under the OBCA
and the by-laws of the Company and such additional documents and instruments as
the Depositary may reasonably require, the holder of such surrendered
certificate shall be entitled to receive in exchange therefor, and the
Depositary shall deliver to such holder, a certificate representing that number
(rounded down to the nearest whole number) of Exchangeable Shares which such
holder has the right to receive (together with any dividends or distributions
with respect thereto pursuant to section 4.3 and any cash in lieu of fractional

                                       A-9

<PAGE>


Exchangeable Shares pursuant to section 4.4), and the certificate so surrendered
shall forthwith be cancelled.  Certificates representing Class B Shares shall
not be issued.  In the event of a transfer of ownership of Company Common Shares
which is not registered in the transfer records of the Company, a certificate
representing the proper number of Exchangeable Shares may be issued to a
transferee if the certificate representing such Company Common Shares is
presented to the Depositary, accompanied by all documents required to evidence
and effect such transfer.  Until surrendered as contemplated by this section
4.1, each certificate which immediately prior to the Effective Date represented
outstanding Company Common Shares that were converted into Class B Shares on the
Amalgamation and thereafter into Exchangeable Shares shall be deemed at any time
after the Effective Date to represent only the right to receive upon such
surrender (i) the certificate representing Exchangeable Shares as contemplated
by this section 4.1, (ii) a cash payment in lieu of any fractional Exchangeable
Shares as contemplated by section 4.4 and (iii) any dividends or distributions
with a record date after the Effective Date theretofore paid or payable with
respect to Exchangeable Shares as contemplated by section 4.3.

     4.2  EXCHANGE OF CERTIFICATES FOR HOLDERS OF COMPANY COMMON SHARES

          On or promptly after the Effective Date, Swissco shall deposit with
the Depositary, for the benefit of the holders of Company Common Shares
converted into Class A Shares pursuant to section 2.1(c) or (k) and thereafter
exchanged for Parent Common Shares pursuant to subsection 2.1(g), certificates
representing the Parent Common Shares issued pursuant to subsection 2.1(g) in
exchange for outstanding Class A Shares.  Upon surrender to the Depositary for
cancellation of a certificate which immediately prior to the Effective Date
represented outstanding Company Common Shares that were converted into Class A
Shares and thereafter exchanged for Parent Common Shares, together with such
other documents and instruments as would have been required to effect the
transfer of the shares formerly represented by such certificate under the OBCA
and the by-laws of the Company and such additional documents and instruments as
the Depositary may reasonably require, the holder of such surrendered
certificate shall be entitled to receive in exchange therefor, and the
Depositary shall deliver to such holder, a certificate representing that number
(rounded down to the nearest whole number) of Parent Common Shares which such
holder has the right to receive (together with any dividends or distributions
with respect thereto pursuant to section 4.3 and any cash in lieu of fractional
Parent Common Shares pursuant to section 4.4), and the certificate so
surrendered shall forthwith be cancelled.  No certificates representing Class A
Shares shall be issued to the holders of Company Common Shares which are
converted into Class A Shares on the Amalgamation.  In the event of a transfer
of ownership of Company Common Shares which is not registered in the transfer
records of the Company, a certificate representing the proper number of Parent
Common Shares may be issued to a transferee if the certificate representing such
Company Common Shares is presented to the Depositary, accompanied by all
documents required to evidence and effect such transfer. Until surrendered as
contemplated by this section 4.2, each certificate which immediately prior to
the Effective Date represented outstanding Company Common Shares that were
converted into Class A Shares on the Amalgamation and thereafter exchanged for
Parent Common Shares shall be deemed at any time after the Effective Date to
represent only the right to receive upon such surrender (i) the certificate
representing

                                      A-10

<PAGE>

Parent Common Shares as contemplated by this section 4.2, (ii) a cash payment in
lieu of any fractional Parent Common Shares as contemplated by section 4.4 and
(iii) any dividends or distributions with a record date after the Effective Date
theretofore paid or payable with respect to Parent Common Shares as contemplated
by section 4.3.

     4.3  DISTRIBUTIONS WITH RESPECT TO UNSURRENDERED CERTIFICATES

          No dividends or other distributions declared or made after the
Effective Date with respect to Exchangeable Shares or Parent Common Shares with
a record date after the Effective Date shall be paid to the holder of any
unsurrendered certificate which immediately prior to the Effective Date
represented outstanding Company Common Shares that were converted or exchanged
pursuant to section 2.1, and no cash payment in lieu of fractional shares shall
be paid to any such holder pursuant to section 4.4, unless and until the holder
of record of such certificate shall surrender such certificate in accordance
with section 4.1 or section 4.2.  Subject to applicable law, at the time of such
surrender of any such certificate (or, in the case of clause (iii) below, at the
appropriate payment date), there shall be paid to the record holder of the
certificates representing whole Exchangeable Shares or Parent Common Shares, as
the case may be, without interest (i) the amount of any cash payable in lieu of
a fractional Exchangeable Share or Parent Common Share to which such holder is
entitled pursuant to section 4.4, (ii) the amount of dividends or other
distributions with a record date after the Effective Date theretofore paid with
respect to such whole Exchangeable Share or Parent Common Share, as the case may
be, and (iii) the amount of dividends or other distributions with a record date
after the Effective Date but prior to surrender and a payment date subsequent to
surrender payable with respect to such whole Exchangeable Share or Parent Common
Share, as the case may be.

     4.4  NO FRACTIONAL SHARES

          No certificates or scrip representing fractional Exchangeable Shares
or Parent Common Shares shall be issued upon the surrender for exchange of
certificates pursuant to section 4.1 or section 4.2 and, subject to the last
sentence of this section 4.4, no dividend, stock split or other change in the
capital structure of the Corporation or Parent shall relate to any such
fractional security and such fractional interests shall not entitle the owner
thereof to vote or to exercise any rights as a security holder of the
Corporation or Parent.  In lieu of any such fractional securities, each person
entitled to a fractional interest in an Exchangeable Share or a fractional
interest in a Parent Common Share will receive from the Corporation (in the case
of fractional interests in Exchangeable Shares) or from Swissco (in the case of
fractional interests in Parent Common Shares) an amount of cash (rounded to the
nearest whole cent), without interest, equal to the product of (i) such
fraction, multiplied by (ii) the average of the closing  price for Parent Common
Shares on the NYSE as of each of the thirty (30) consecutive trading days
immediately preceding the Effective Date as quoted in the Wall Street Journal or
other reliable financial newspaper or publication.  For the purposes of the
preceding sentence, a "trading day" means a day on which trading generally takes
place on the NYSE and on which trading in Parent Common Shares has occurred.

<PAGE>

          The determination as to whether any former holder of Class A Shares
would, apart from this section 4.4, be entitled to receive a fractional interest
in a Parent Common Share shall be made once only, and the determination as to
whether any former holder of Class B Shares would, apart from this section 4.4,
be entitled to receive a fractional interest in an Exchangeable Share shall be
made once only.

     4.5  LOST CERTIFICATES

          In the event any certificate which immediately prior to the Effective
Date represented outstanding Company Common Shares that were converted or
exchanged pursuant to section 2.1 shall have been lost, stolen or destroyed,
upon the making of an affidavit of that fact by the person claiming such
certificate to be lost, stolen or destroyed, the Depositary will issue in
exchange for such lost, stolen or destroyed certificate, certificates
representing Exchangeable Shares or Parent Common Shares (and any dividends or
distributions with respect thereto and any cash pursuant to section 4.4)
deliverable in respect thereof as determined in accordance with section 2.1.
When authorizing such payment in exchange for any lost, stolen or destroyed
certificate, the person to whom certificates representing Exchangeable Shares or
Parent Common Shares are to be issued shall, at the discretion of Swissco, as a
condition precedent to the issuance thereof, give a bond satisfactory to the
Corporation or Swissco, as the case may be, in such sum as the Corporation or
Swissco may direct or otherwise indemnify the Corporation or Swissco in a manner
satisfactory to the Corporation or Swissco against any claim that may be made
against the Corporation or Swissco with respect to the certificate alleged to
have been lost, stolen or destroyed.

     4.6  EXTINGUISHMENT OF RIGHTS

          Any certificate which immediately prior to the Effective Date
represented outstanding Company Common Shares that were converted or exchanged
pursuant to section 2.1 and not deposited, with all other instruments required
by section 4.1 or section 4.2, on or prior to the tenth anniversary of the
Effective Date shall cease to represent a claim or interest of any kind or
nature as a shareholder of the Company, the Corporation or Parent.  On such
date, the Exchangeable Shares or Parent Common Shares to which the former
registered holder of the certificate referred to in the preceding sentence was
ultimately entitled shall be deemed to have been surrendered to the Corporation
or Swissco, as the case may be, together with all entitlements to dividends,
distributions and interests thereon held for such former registered holder.

     4.7  ELECTIONS

          (a)  Subject to section 2.1(k), each record holder immediately prior
to the Effective Date of Company Common Shares will be entitled to elect to
receive Class B Shares for all of such shares (an "Election").  All such
elections shall be made on a Letter of Transmittal and Election Form.  Record
holders of Company Common Shares who hold Company Common Shares as nominees,
trustees or in other representative capacities (a

                                      A-12

<PAGE>

"Representative") may submit multiple Letters of Transmittal and Election Forms;
PROVIDED, THAT, such Representative certifies that each such Letter of
Transmittal and Election Form covers all the Company Common Shares held by each
Representative for a particular beneficial owner.

          (b)  TIMELY ELECTIONS, ETC.  Elections shall be made by holders of
Company Common Shares by mailing to the Depositary a Letter of Transmittal and
Election Form.  To be effective, a Letter of Transmittal and Election Form must
be properly completed, signed and submitted to the Depositary.  Parent will have
the discretion, which it may delegate in whole or in part to the Depositary, to
determine whether Letters of Transmittal and Election Forms have been properly
completed, signed and submitted or revoked and to disregard immaterial defects
in Letters of Transmittal and Election Forms.  The decision of Parent (or the
Depositary) in such matters shall be conclusive and binding.  Neither Parent nor
the Depositary will be under any obligation to notify any person of any defect
in a Letter of Transmittal and Election Form submitted to the Depositary.

          (c)  DEEMED NON-ELECTION.  For the purposes hereof, a holder of
Company Common Shares who does not submit a Letter of Transmittal and Election
Form which is received by the Depositary prior to the Election Deadline (as
hereinafter defined) shall be deemed not to have made an election, and shall
receive Class A Shares.  If Parent or the Depositary shall determine that any
purported election was not properly made, such purported election shall be
deemed to be of no force and effect.

          (d)  MAILING.  Parent and the Company shall each use their best
efforts to mail the Letter of Transmittal and Election Form to all persons who
become holders of Company Common Shares during the period between the record
date for the Meeting and 10:00 a.m. Toronto time, on the date seven calendar
days prior to the anticipated Effective Date and to make the Letter of
Transmittal and Election Form available to all persons who become holders of
Company Common Shares subsequent to such day and no later than the close of
business on the business day prior to the Effective Date.  A Letter of
Transmittal and Election Form must be received by the Depositary by the close of
business on the last business day prior to the Effective Date (the "Election
Deadline") in order to be effective.  A Letter of Transmittal and Election Form
may not be revoked after receipt thereof by the Depositary.


                          ARTICLE 5--CERTAIN RIGHTS OF
                     SWISSCO TO ACQUIRE EXCHANGEABLE SHARES

     5.1  SWISSCO LIQUIDATION CALL RIGHT

          (a)  Swissco shall have the overriding right (the "Liquidation Call
Right"), in the event of and notwithstanding the proposed liquidation,
dissolution or winding-up of the Corporation pursuant to Article 5 of the
Exchangeable Share Provisions, to purchase from all but not less than all of the
holders of Exchangeable Shares on the Liquidation Date all but not

                                      A-13

<PAGE>

less than all of the Exchangeable Shares held by each such holder on payment by
Swissco of an amount per share equal to (a) the Current Market Price (as defined
in the Exchangeable Share Provisions) of a Parent Common Share on the last
Business Day prior to the Liquidation Date, which shall be satisfied in full by
causing to be delivered to such holder one Parent Common Share, plus (b) an
additional amount equivalent to the full amount of all dividends declared and
unpaid on such Exchangeable Share and all dividends declared on Parent Common
Shares which have not been declared on such Exchangeable Shares in accordance
with section 3.1 of the Exchangeable Share Provisions (collectively the
"Liquidation Call Purchase Price," provided that if the record date for any such
declared and unpaid dividends occurs on or after the Liquidation Date, the
Liquidation Call Purchase Price shall not include such additional amount
equivalent to such dividends).  In the event of the exercise of the Liquidation
Call Right by Swissco, each holder shall be obligated to sell all the
Exchangeable Shares held by the holder to Swissco on the Liquidation Date on
payment by Swissco to the holder of the Liquidation Call Purchase Price for each
such share.

          (b)  To exercise the Liquidation Call Right, Swissco must notify the
Corporation's transfer agent (the "Transfer Agent"), as agent for the holders of
Exchangeable Shares, and the Corporation of Swissco's intention to exercise such
right at least 55 days before the Liquidation Date in the case of a voluntary
liquidation, dissolution or winding up of the Corporation and at least five
Business Days before the Liquidation Date in the case of an involuntary
liquidation, dissolution or winding up of the Corporation.  The Transfer Agent
will notify the holders of Exchangeable Shares as to whether or not Swissco has
exercised the Liquidation Call Right forthwith after the expiry of the period
during which the same may be exercised by Swissco.  If Swissco exercises the
Liquidation Call Right, on the Liquidation Date Swissco will purchase and the
holders will sell all of the Exchangeable Shares then outstanding for a price
per share equal to the Liquidation Call Purchase Price.

          (c)  For the purposes of completing the purchase of the Exchangeable
Shares pursuant to the Liquidation Call Right, Swissco shall deposit with the
Transfer Agent, on or before the Liquidation Date, certificates representing the
aggregate number of Parent Common Shares deliverable by Swissco in payment of
the total Liquidation Call Purchase Price and a cheque or cheques in the amount
of the remaining portion, if any, of the total Liquidation Call Purchase Price.
 Provided that the total Liquidation Call Purchase Price has been so deposited
with the Transfer Agent, on and after the Liquidation Date the rights of each
holder of Exchangeable Shares will be limited to receiving such holder's
proportionate part of the total Liquidation Call Purchase Price payable by
Swissco upon presentation and surrender by the holder of certificates
representing the Exchangeable Shares held by such holder and the holder shall on
and after the Liquidation Date be considered and deemed for all purposes to be
the holder of the Parent Common Shares delivered to it. Upon surrender to the
Transfer Agent of a certificate or certificates representing Exchangeable
Shares, together with such other documents and instruments as may be required to
effect a transfer of Exchangeable Shares under the OBCA and the by-laws of the
Corporation and such additional documents and instruments as the Transfer Agent
may reasonably require, the holder of such surrendered certificate or
certificates shall be entitled to receive in exchange therefor, and the Transfer
Agent on behalf

                                      A-14

<PAGE>

of Swissco shall deliver to such holder, certificates representing the Parent
Common Shares to which the holder is entitled and a cheque or cheques of Swissco
payable at par and in Canadian dollars at any branch of the bankers of Swissco
or of the Corporation in Canada in payment of the remaining portion, if any, of
the total Liquidation Call Purchase Price.  If Swissco does not exercise the
liquidation Call Right in the manner described above, on the Liquidation Date
the holders of the Exchangeable Shares will be entitled to receive in exchange
therefor the liquidation price otherwise payable by the Corporation in
connection with the liquidation, dissolution or winding-up of the Corporation
pursuant to Article 5 of the Exchangeable Share Provisions.

     5.2  SWISSCO REDEMPTION CALL RIGHT

          (a)  Swissco shall have the overriding right (the "Redemption Call
Right"), notwithstanding the proposed redemption of Exchangeable Shares by the
Corporation pursuant to Article 7 of the Exchangeable Share Provisions, to
purchase from all but not less than all of the holders of Exchangeable Shares to
be redeemed on the Redemption Date all but not less than all of the Exchangeable
Shares held by each such holder on payment by Swissco to the holder of an amount
per share equal to (a) the Current Market Price (as defined in the Exchangeable
Share Provisions) of a Parent Common Share on the last Business Day prior to the
Redemption Date which shall be satisfied in full by causing to be delivered to
such holder one Parent Common Share plus (b) an additional amount equivalent to
the full amount of all dividends declared and unpaid on such Exchangeable Share
and all dividends declared on Parent Common Shares that have not been declared
on such Exchangeable Share in accordance with section 3.1 of the Exchangeable
Share Provisions (collectively the "Redemption Call Purchase Price," provided
that if the record date for any such declared and unpaid dividends occurs on or
after the Redemption Date, the Redemption Call Purchase Price shall not include
such additional amount equivalent to such dividends).  In the event of the
exercise of the Redemption Call Right by Swissco, each holder shall be obligated
to sell all the Exchangeable Shares held by the holder and otherwise to be
redeemed to Swissco on the Redemption Date on payment by Swissco to the holder
of the Redemption Call Purchase Price for each such share.

          (b)  To exercise the Redemption Call Right, Swissco must notify the
Transfer Agent, as agent for the holders of Exchangeable Shares, and the
Corporation of Swissco's intention to exercise such right at least 125 days
before the Automatic Redemption Date (in the case of the Automatic Redemption)
or at least 35 days before the Section 12(g) Redemption Date (in the case of
Section 12(g) Redemption).  The Transfer Agent will notify the holders of the
Exchangeable Shares as to whether or not Swissco has exercised the Redemption
Call Right forthwith after the expiry of the period during which the same may be
exercised by Swissco.  If Swissco exercises the Redemption Call Right, on the
Redemption Date Swissco will purchase and the holders will sell all of the
Exchangeable Shares to be redeemed for a price per share equal to the Redemption
Call Purchase Price.

          (c)  For the purposes of completing the purchase of Exchangeable
Shares pursuant to the Redemption Call Right, Swissco shall deposit with the
Transfer Agent, on or

                                      A-15

<PAGE>

before the Redemption Date, certificates representing the aggregate number of
Parent Common Shares deliverable by Swissco in payment of the total Redemption
Call Purchase Price and a cheque or cheques in the amount of the remaining
portion, if any, of the total Redemption Call Purchase Price.  Provided that the
total Redemption Call Purchase Price has been so deposited with the Transfer
Agent, on and after the Redemption Date the rights of each holder of
Exchangeable Shares so purchased will be limited to receiving such holder's
proportionate part of the total Redemption Call Purchase Price payable by
Swissco upon presentation and surrender by the holder of certificates
representing the Exchangeable Shares purchased by Swissco from such holder and
the holder shall on and after the Redemption Date be considered and deemed for
all purposes to be the holder of the Parent Common Shares delivered to such
holder.  Upon surrender to the Transfer Agent of a certificate or certificates
representing Exchangeable Shares, together with such other documents and
instruments as may be required to effect a transfer of Exchangeable Shares under
the OBCA and the by-laws of the Corporation and such additional documents and
instruments as the Transfer Agent may reasonably require, the holder of such
surrendered certificate or certificates shall be entitled to receive in exchange
therefor, and the Transfer Agent on behalf of Swissco shall deliver to such
holder, certificates representing the Parent Common Shares to which the holder
is entitled and a cheque or cheques of Swissco payable at par and in Canadian
dollars at any branch of the bankers of Swissco or of the Corporation in Canada
in payment of the remaining portion, if any, of the total Redemption Call
Purchase Price.  If Swissco does not exercise the Redemption Call Right in the
manner described above, on the Redemption Date the holders of the Exchangeable
Shares will be entitled to receive in exchange therefor the redemption price
otherwise payable by the Corporation in connection with the redemption of
Exchangeable Shares pursuant to Article 7 of the Exchangeable Share Provisions.

     5.3  WITHHOLDING RIGHTS.

          Parent, Swissco and the Depositary shall be entitled to deduct and
withhold from the consideration otherwise payable pursuant to this Plan of
Arrangement to any holder of Company Common Shares, Class A Shares, Class B
Shares, or Exchangeable Shares such amounts as Parent, Swissco or the Depositary
is required or permitted to deduct and withhold with respect to such payment
under the United States Internal Revenue Code of 1986, as amended, the INCOME
TAX ACT (Canada) or any provision of state, local, provincial or foreign tax
law.  To the extent that amounts are so withheld, such withheld amounts shall be
treated for all purposes hereof as having been paid to the holder of shares in
respect of which such deduction and withholding was made, provided that such
withheld amounts are actually remitted to the appropriate taxing authority.  To
the extent that the amount so required or permitted to be deducted or withheld
from any payment to a holder exceeds the cash portion of the consideration
otherwise payable to the holder, the Parent, Swissco and the Depositary are
hereby authorized to sell or otherwise dispose of at fair market value such
portion of such consideration as is necessary to provide sufficient funds to the
Parent, Swissco or the Depositary, as the case may be, in order to enable it to
comply with such deduction or withholding requirement and Parent or the
Depositary shall give an accounting to the holder with respect thereto and any
balance of such proceeds of sale.

Shares shall be entitled, subject to applicable law, to receive from the assets

winding-up, before any distribution of any part of the assets of the Corporation
among the holders of the Class A Shares, the Class B Shares or any other shares
ranking junior to the Exchangeable Shares, an amount per share equal to (a) the
Current Market Price of a Parent Common Share on the last Business Day prior to

dividends on each such Exchangeable Share and all dividends declared on Parent

to be delivered to the holders of the Exchangeable Shares the Liquidation Amount
(less any tax required to be deducted and withheld therefrom by the Corporation)
for each such Exchangeable Share upon

<PAGE>

presentation and surrender of the certificates representing such Exchangeable
Shares together with such other documents and instruments as may be required to
effect a transfer of Exchangeable Shares under the BUSINESS CORPORATIONS ACT
(Ontario) and the by-laws of the Corporation and such additional documents and
instruments as the Transfer Agent may be specified by the Corporation by notice
to the holders of the Exchangeable Shares. Payment of the total Liquidation
Amount for such Exchangeable Shares shall be made by delivery to each holder, at
the address of the holder recorded in the securities register of the Corporation
for the Exchangeable Shares or by holding for pick up by the holder at the
registered office of the Corporation or at any office of the Transfer Agent as
may be specified by the Corporation by notice to the holders of Exchangeable
Shares, on behalf of the Corporation of certificates representing Parent Common
Shares (which shares shall be duly issued as fully paid and non-assessable and
shall be free and clear of any lien, claim or encumbrance) and a cheque of the
Corporation payable at par at any branch of the bankers of the Corporation in
respect of the amount equivalent to the full amount of all declared and unpaid
dividends and all dividends declared on Parent Common Shares which have not been
declared on such Exchangeable Shares in accordance with section 3.1 of the
Exchangeable Share Provisions, comprising part of the total Liquidation Amount
(less any tax required to be deducted and withheld therefrom by the
Corporation).  On and after the Liquidation Date, the holders of the
Exchangeable Shares shall cease to be holders of such Exchangeable Shares and
shall not be entitled to exercise any of the rights of holders in respect
thereof, other than the right to receive their proportionate part of the total
Liquidation Amount, unless payment of the total Liquidation Amount for such
Exchangeable Shares shall not be made upon presentation and surrender of share
certificates in accordance with the foregoing provisions, in which case the
rights of the holders shall remain unaffected until the total Liquidation Amount
has been paid in the manner hereinbefore provided. The Corporation shall have
the right at any time after the Liquidation Date to deposit or cause to be
deposited the total Liquidation Amount in respect of the Exchangeable Shares
represented by certificates that have not at the Liquidation Date been
surrendered by the holders thereof in a custodial account with any chartered
bank or trust company in Canada. Upon such deposit being made, the rights of the
holders of Exchangeable Shares after such deposit shall be limited to receiving
their proportionate part of the total Liquidation Amount (less any tax required
to be deducted and withheld therefrom) for such Exchangeable Shares so
deposited, against presentation and surrender of the said certificates held by
them, respectively, in accordance with the foregoing provisions. Upon such
payment or deposit of the total Liquidation Amount, the holders of the
Exchangeable Shares shall thereafter be considered and deemed for all purposes
to be the holders of the Parent Common Shares delivered to them. To the extent
that the amount of tax required to be deducted or withheld from any payment to a
holder of Exchangeable Shares exceeds the cash portion of such payment, the
Corporation is hereby authorized to sell or otherwise dispose of at fair market
value such portion of the property then payable to the holder as is necessary to
provide sufficient funds to the Corporation in order to enable it to comply with
such deduction or withholding requirement and the Corporation shall give an
accounting to the holder with respect thereto and any balance of such proceeds
of sale.

holders of the Exchangeable Shares the Liquidation Amount per Exchangeable Share
pursuant to Section 5.1 of these share provisions, such holders shall not be
entitled to share in any further distribution of the assets of the Corporation.

subject to applicable law and the exercise by Swissco of the Retraction Call
Right and otherwise upon compliance with the provisions of this Article 6, to

Share Provisions (collectively the "Retraction Price," provided that if the
record date for any such declared and unpaid dividends occurs on or after the
Retraction Date the Retraction Price shall not include such additional amount
equivalent to such dividends).  To effect such redemption, the holder shall
present and surrender at the registered office of the Corporation or at any
office of the Transfer Agent as may be specified by the Corporation by notice to
the holders of Exchangeable Shares the certificate or certificates representing
the Exchangeable Shares which the holder desires to have the Corporation redeem,
together with such other documents and instruments as may be required to effect
a transfer of Exchangeable Shares under the BUSINESS CORPORATIONS ACT (Ontario)
and the by-laws of the Corporation and such additional documents and instruments
as the transfer Agent may reasonably require, and together with a duly executed
statement (the "Retraction Request") in such form as may be acceptable to the
Corporation:

               (a)  specifying that the holder desires to have all or any number
     specified therein of the Exchangeable Shares represented by such
     certificate or certificates (the "Retracted Shares") redeemed by the
     Corporation;

               (b)  stating the Business Day on which the holder desires to have
     the Corporation redeem the Retracted Shares (the "Retraction Date"),
     provided that the Retraction Date shall be not less than five Business Days
     nor more than 10 Business Days after the date on which the Retraction
     Request is received by the Corporation and further provided that, in the
     event that no such Business Day is specified by the holder in the
     Retraction Request, the Retraction Date shall be deemed to be the tenth
     Business Day after the date on which the Retraction Request is received by
     the Corporation; and

                                      A-27

<PAGE>

               (c)  acknowledging the overriding right (the "Retraction Call
     Right") of Swissco to purchase all but not less than all the Retracted
     Shares directly from the holder and that the Retraction Request shall be
     deemed to be a revocable offer by the holder to sell the Retracted Shares
     to Swissco in accordance with the Retraction Call Right on the terms and
     conditions set out in Section 6.3 below.

          6.2  Subject to the exercise by Swissco of the Retraction Call Right,
upon receipt by the Corporation or the Transfer Agent in the manner specified in
Section 6.1 hereof of a certificate or certificates representing the number of
Exchangeable Shares which the holder desires to have the Corporation redeem,
together with a Retraction Request, and provided that the Retraction Request is
not revoked by the holder in the manner specified in Section 6.7, the
Corporation shall redeem the Retracted Shares effective at the close of business
on the Retraction Date and shall cause to be delivered to such holder the total
Retraction Price with respect to such shares. If only a part of the Exchangeable
Shares represented by any certificate are redeemed (or purchased by Swissco
pursuant to the Retraction Call Right), a new certificate for the balance of
such Exchangeable Shares shall be issued to the holder at the expense of the
Corporation.

          6.3  Upon receipt by the Corporation of a Retraction Request, the
Corporation shall immediately notify Swissco and Parent thereof.  In order to
exercise the Retraction Call Right, Parent or Swissco must notify the
Corporation in writing of Swissco's determination to do so (the "Parent
(Swissco) Call Notice") within two Business Days of notification to Parent and
Swissco by the Corporation of the receipt by the Corporation of the Retraction
Request.  If Parent or Swissco does not so notify the Corporation within such
two Business Day period, the Corporation will notify the holder as soon as
possible thereafter that Swissco will not exercise the Retraction Call Right.
If Parent or Swissco delivers the Parent (Swissco) Call Notice within such two
Business Day time period, and provided that the Retraction Request is not
revoked by the holder in the manner specified in Section 6.7, the Retraction
Request shall thereupon be considered only to be an offer by the holder to sell
the Retracted Shares to Swissco in accordance with the Retraction Call Right. In
such event, the Corporation shall not redeem the Retracted Shares and Swissco
shall purchase from such holder and such holder shall sell to Swissco on the
Retraction Date the Retracted Shares for a purchase price (the "Purchase Price")
per share equal to the Retraction Price per share.  For the purposes of
completing a purchase pursuant to the Retraction Call Right, Swissco shall
deposit with the Transfer Agent, on or before the Retraction Date, certificates
representing Parent Common Shares and a cheque in the amount of the remaining
portion, if any, of the total Purchase Price.  Provided that the total Purchase
Price has been so deposited with the Transfer Agent, the closing of the purchase
and sale of the Retracted Shares pursuant to the Retraction Call Right shall be
deemed to have occurred as at the close of business on the Retraction Date and,
for greater certainty, no redemption by the Corporation of such Retracted Shares
shall take place on the Retraction Date.  In the event that neither Parent nor
Swissco delivers a Parent (Swissco) Call Notice within such two Business Day
period, and provided that Retraction Request is not revoked by the holder in the
manner specified in

                                      A-28

<PAGE>

Section 6.7, the Corporation shall redeem the Retracted Shares on the Retraction
Date and in the manner otherwise contemplated in this Article 6.

          6.4  The Corporation or Swissco, as the case may be, shall deliver or
cause the Transfer Agent to deliver to the relevant holder, at the address of
the holder recorded in the securities register of the Corporation for the
Exchangeable Shares or at the address specified in the holder's Retraction
Request or by holding for pick up by the holder at the registered office of the
Corporation or at any office of the Transfer Agent as may be specified by the
Corporation by notice to the holders of Exchangeable Shares, certificates
representing the Parent Common Shares (which shares shall be duly issued as
fully paid and non-assessable and shall be free and clear of any lien, claim or
encumbrance) registered in the name of the holder or in such other name as the
holder may request in payment of the total Retraction Price or the total
Purchase Price, as the case may be, and a cheque of the Corporation payable at
par at any branch of the bankers of the Corporation in payment of the remaining
portion, if any, of the total Retraction Price (less any tax required to be
deducted and withheld therefrom by the Corporation) or a cheque of Swissco
payable at par and in Canadian dollars at any branch of the bankers of Swissco
or of the Corporation in Canada in payment of the remaining portion, if any, of
the total Purchase Price, as the case may be, and such delivery of such
certificates and cheque on behalf of the Corporation or by Swissco, as the case
may be, or by the Transfer Agent shall be deemed to be payment of and shall
satisfy and discharge all liability for the total Retraction Price or total
Purchase Price, as the case may be, to the extent that the same is represented
by such share certificates and cheque (less any tax required and in fact
deducted and withheld therefrom and remitted to the proper tax authority),
unless such cheque is not paid on due presentation.  To the extent that the
amount of tax required to be deducted or withheld from any payment to a holder
of Exchangeable Shares exceeds the cash portion of such payment, the Corporation
or Swissco, as the case may be, is hereby authorized to sell or otherwise
dispose of at fair market value such portion of the property then payable to the
holder as is necessary to provide sufficient funds to the Corporation in order
to enable it to comply with such deduction or withholding requirement and shall
give an accounting to the holder with respect thereto and any balance of such
proceeds of sale.

          6.5  On and after the close of business on the Retraction Date, the
holder of the Retracted Shares shall cease to be a holder of such Retracted
Shares and shall not be entitled to exercise any of the rights of a holder in
respect thereof, other than the right to receive his proportionate part of the
total Retraction Price or total Purchase Price, as the case may be, unless upon
presentation and surrender of certificates in accordance with the foregoing
provisions, payment of the total Retraction Price or the total Purchase Price,
as the case may be, shall not be made, in which case the rights of such holder
shall remain unaffected until the total Retraction Price or the total Purchase
Price, as the case may be, has been paid in the manner hereinbefore provided.
On and after the close of business on the Retraction Date, provided that
presentation and surrender of certificates and payment of the total Retraction
Price or the total Purchase Price, as the case may be, has been made in
accordance with the foregoing provisions, the holder of the Retracted Shares so
redeemed by

                                      A-29

<PAGE>

the Corporation or purchased by Swissco shall thereafter be considered and
deemed for all purposes to be a holder of the Parent Common Shares delivered to
it.

          6.6  Notwithstanding any other provision of this Article 6, the
Corporation shall not be obligated to redeem Retracted Shares specified by a
holder in a Retraction Request to the extent that such redemption of Retracted
Shares would be contrary to solvency requirements or other provisions of
applicable law.  If the Corporation believes that on any Retraction Date it
would not be permitted by any of such provisions to redeem the Retracted Shares
tendered for redemption on such date, and provided that Swissco shall not have
exercised the Retraction Call Right with respect to the Retracted Shares, the
Corporation shall only be obligated to redeem Retracted Shares specified by a
holder in a Retraction Request to the extent of the maximum number that may be
so redeemed (rounded down to a whole number of shares) as would not be contrary
to such provisions and shall notify the holder at least two Business Days prior
to the Retraction Date as to the number of Retracted Shares which will not be
redeemed by the Corporation. In any case in which the redemption by the
Corporation of Retracted Shares would be contrary to solvency requirements or
other provisions of applicable law, the Corporation shall redeem Retracted
Shares in accordance with Section 6.2 of these share provisions on a pro rata
basis and shall issue to each holder of Retracted Shares a new certificate, at
the expense of the Corporation, representing the Retracted Shares not redeemed
by the Corporation pursuant to Section 6.2 hereof.  Provided that the Retraction
Request is not revoked by the holder in the manner specified in Section 6.7, the
holder of any such Retracted Shares not redeemed by the Corporation pursuant to
Section 6.2 of these share provisions as a result of solvency requirements of
applicable law shall be deemed by giving the Retraction Request to require
Swissco to purchase such Retracted Shares from such holder on the Retraction
Date or as soon as practicable thereafter on payment by Swissco to such holder
of the Purchase Price for each such Retracted Share, all as more specifically
provided in the Voting and Exchange Trust Agreement.

          6.7  A holder of Retracted Shares may, by notice in writing given by
the holder to the Corporation before the close of business on the Business Day
immediately preceding the Retraction Date, withdraw its Retraction Request in
which event such Retraction Request shall be null and void and, for greater
certainty, the revocable offer constituted by the Retraction Request to sell the
Retracted Shares to Swissco shall be deemed to have been revoked.

                                    ARTICLE 7
              REDEMPTION OF EXCHANGEABLE SHARES BY THE CORPORATION

          7.1  Subject to applicable law, and subject to the exercise by Swissco
of the Redemption Call Right, (a) the Corporation shall on the Automatic
Redemption Date redeem (the "Automatic Redemption") the whole of the then
outstanding Exchangeable Shares for an amount per share equal to (i) the Current
Market Price of a Parent Common Share on the last Business Day prior to the
Automatic Redemption Date, which shall be satisfied in full by the Corporation
causing to be delivered to each holder of Exchangeable Shares one Parent

                                      A-30

<PAGE>

Common Share for each Exchangeable Share held by such holder, plus (ii) an
additional amount equivalent to the full amount of all declared and unpaid
dividends thereon and all dividends declared on Parent Common Shares which have
not been declared on such Exchangeable Shares in accordance with section 3.1 of
the Exchangeable Share Provisions (collectively the "Redemption Price," provided
that if the record date for any such declared and unpaid dividends occurs on or
after the Redemption Date the Redemption Price shall not include such additional
amount equivalent to such dividends), and (b) the Corporation may, at any time
when the Corporation reasonably determines that Exchangeable Shares are "held of
record" (as such term is defined in Rule 12g5-1 promulgated under the United
States Securities Exchange Act of 1934, as amended (the "Exchange Act")) by 500
or more persons ("Record Holders"), redeem (a "Section 12(g) Redemption") that
portion of the then outstanding Exchangeable Shares held by that number of
Record Holders equal to the difference of (A) the total number of Record Holders
and (B) 499, or such smaller number that the Corporation reasonably determines
is necessary to take the position that it need not register the Exchangeable
Shares pursuant to Section 12(g) of the Exchange Act, the identity of such
Record Holders to be determined by the Corporation by lot or other fair method
of random determination, for an amount per share equal to the Redemption Price.

          7.2  In any case of any redemption of Exchangeable Shares under this
Article 7, the Corporation shall, at least 120 days before the Automatic
Redemption Date (in the case of the Automatic Redemption), or at least 30 days
before the date of a Section 12(g) Redemption (a "Section 12(g) Redemption
Date"; the Automatic Redemption Date or a Section 12(g) Redemption Date, as
applicable, being referred to as a "Redemption Date"), send or cause to be sent
to each holder of Exchangeable Shares to be redeemed a notice in writing of the
redemption by the Corporation or the purchase by Swissco under the Redemption
Call Right, as the case may be, of the Exchangeable Shares held by such holder.
Such notice shall set out the formula for determining the Redemption Price or
the Redemption Call Purchase Price, as the case may be, the Redemption Date and,
if applicable, particulars of the Redemption Call Right. On or after the
Redemption Date and subject to the exercise by Swissco of the Redemption Call
Right, the Corporation shall cause to be delivered to the holders of the
Exchangeable Shares to be redeemed the Redemption Price (less any tax required
to be deducted and withheld therefrom by the Corporation) for each such
Exchangeable Share upon presentation and surrender at the registered office of
the Corporation or at any office of the Transfer Agent as may be specified by
the Corporation in such notice of the certificates representing such
Exchangeable Shares, together with such other documents and instruments as may
be required to effect a transfer of Exchangeable Shares under the BUSINESS
CORPORATIONS ACT (Ontario) and the by-laws of the Corporation and such
additional documents and instruments as the Transfer Agent may reasonably
require. Payment of the total Redemption Price for such Exchangeable Shares
shall be made by delivery to each holder, at the address of the holder recorded
in the securities register of the Corporation or by holding for pick up by the
holder at the registered office of the Corporation or at any office of the
Transfer Agent as may be specified by the Corporation in such notice, on behalf
of the Corporation of certificates representing Parent Common Shares (which
shares shall be duly issued as fully paid and non-assessable and shall be free
and clear

                                      A-31

<PAGE>

of any lien, claim or encumbrance) and a cheque of the Corporation payable at
par at any branch of the bankers of the Corporation in respect of the additional
amount equivalent to the full amount of all declared and unpaid dividends and
all dividends declared on Parent Common Shares which have not been declared on
such Exchangeable Shares in accordance with section 3.1 of the Exchangeable
Share Provisions comprising part of the total Redemption Price (less any tax
required to be deducted and withheld therefrom by the Corporation).  On and
after the Redemption Date, the holders of the Exchangeable Shares called for
redemption shall cease to be holders of such Exchangeable Shares and shall not
be entitled to exercise any of the rights of holders in respect thereof, other
than the right to receive their proportionate part of the total Redemption
Price, unless payment of the total Redemption Price for such Exchangeable Shares
shall not be made upon presentation and surrender of certificates in accordance
with the foregoing provisions, in which case the rights of the holders shall
remain unaffected until the total Redemption Price has been paid in the manner
hereinbefore provided.  The Corporation shall have the right at any time after
the sending of notice of its intention to redeem Exchangeable Shares as
aforesaid to deposit or cause to be deposited the total Redemption Price of the
Exchangeable Shares so called for redemption, or of such of the said
Exchangeable Shares represented by certificates that have not at the
date of such deposit been surrendered by the holders thereof in connection with
such redemption, in a custodial account with any chartered bank or trust company
in Canada named in such notice.  Upon the later of such deposit being made and
the Redemption Date, the Exchangeable Shares in respect whereof such deposit
shall have been made shall be redeemed and the rights of the holders thereof
after such deposit or Redemption Date, as the case may be, shall be limited to
receiving their proportionate part of the total Redemption Price (less any tax
required to be deducted and withheld therefrom by the Corporation) for such
Exchangeable Shares so deposited, against presentation and surrender of the said
certificates held by them, respectively, in accordance with the foregoing
provisions upon such payment or deposit of the total Redemption Price, the
holders of the Exchangeable Shares shall thereafter be considered and deemed for
all purposes to be holders of the Parent Common Shares delivered to them.  To
the extent that the amount of tax required to be deducted or withheld from any
payment to a holder of Exchangeable Shares exceeds the cash portion of such
payment, the Corporation is hereby authorized to sell or otherwise dispose of at
fair market value such portion of the property then payable to the holder as is
necessary to provide sufficient funds to the Corporation in order to enable it
to comply with such deduction or withholding requirement and shall give an
accounting to the holder with respect thereto and any balance of such proceeds
of sale.

                                    ARTICLE 8
                            PURCHASE FOR CANCELLATION

          8.1  Subject to applicable law and the articles of the Corporation,
the Corporation may at any time and from time to time purchase for cancellation
all or any part of the outstanding Exchangeable Shares at any price by tender to
all the holders of record of Exchangeable Shares then outstanding or through the
facilities of any stock exchange on which the Exchangeable Shares are listed or
quoted at any price per share together with an

                                      A-32

<PAGE>

amount equal to all declared and unpaid dividends thereon. If in response to an
invitation for tenders under the provisions of this Section 8.1, more
Exchangeable Shares are tendered at a price or prices acceptable to the
Corporation than the Corporation is prepared to purchase, the Exchangeable
Shares to be purchased by the Corporation shall be purchased as nearly as may be
pro rata according to the number of shares tendered by each holder who submits a
tender to the Corporation, provided that when shares are tendered at different
prices, the pro rating shall be effected (disregarding fractions) only with
respect to the shares tendered at the price at which more shares were tendered
than the Corporation is prepared to purchase after the Corporation has purchased
all the shares tendered at lower prices. If part only of the Exchangeable Shares
represented by any certificate shall be purchased, a new certificate for the
balance of such shares shall be issued at the expense of the Corporation.

                                   ARTICLE 9
                                  VOTING RIGHTS

          9.1  Except as required by applicable law, the holders of the
Exchangeable Shares shall not be entitled as such to receive notice of or to
attend any meeting of the shareholders of the Corporation or to vote at any such
meeting.


          9.2  Pursuant to the Voting and Exchange Trust Agreement (which by
this reference is incorporated into the rights, privileges, restrictions and
conditions attaching to the Exchangeable Shares as if set forth herein in its
entirety) the holders of Exchangeable Shares (other than the Parent, its
subsidiaries and Affiliates) shall be entitled to receive notice of and instruct
the Trustee under the Voting and Exchange Trust Agreement to exercise voting
rights at meetings of holders of Parent Common Shares, all as provided for in
the Voting and Exchange Trust Agreement.


                                   ARTICLE 10
                             AMENDMENT AND APPROVAL

          10.1 The rights, privileges, restrictions and conditions attaching to
the Exchangeable Shares may be added to, changed or removed but only with the

          10.2 Any approval given by the holders of the Exchangeable Shares to
add to, change or remove any right, privilege, restriction or condition
attaching to the Exchangeable Shares or any other matter requiring the approval
or consent of the holders of the Exchangeable Shares shall be deemed to have
been sufficiently given if it shall have been given in accordance with
applicable law subject to a minimum requirement that such approval be evidenced
by resolution passed by not less than two-thirds of the votes cast on such
resolution at a meeting of holders of Exchangeable Shares duly called and held
at which the holders of at least 50% of the outstanding Exchangeable Shares at
that time are present or represented by proxy; provided that if at any such
meeting the holders of at least 50% of the

                                      A-33

<PAGE>

outstanding Exchangeable Shares at that time are not present or represented by
proxy within one-half hour after the time appointed for such meeting then the
meeting shall be adjourned to such date not less than 10 days thereafter and to
such time and place as may be designated by the Chairman of such meeting.  At
such adjourned meeting the holders of Exchangeable Shares present or represented
by proxy thereat may transact the business for which the meeting was originally
called and a resolution passed thereat by the affirmative vote of not less than
two-thirds of the votes cast on such resolution at such meeting shall constitute
the approval or consent of the holders of the Exchangeable Shares.

          10.3 Exchangeable Shares held by Parent, Swissco or their Affiliates
shall not be included for the purposes of determining a quorum, and shall not
vote, in connection with any approval contemplated by Section 10.2 of these
share provisions.

shares of the common stock, no par value, of the Company (the "Company Common
Stock") will, through a series of steps, ultimately be exchanged for or
converted into shares of the common stock, par value $0.001 per share, of Parent
(the "Parent Common Stock"), or, if elected pursuant to the Agreement,
exchangeable shares, no par value, of Company exchangeable shares (the
"Exchangeable Shares"), in each case on the basis described in the Agreement.
Capitalized terms not otherwise defined herein shall have the meanings ascribed
thereto in the Agreement.

          The undersigned has been advised that as of the date hereof it may be
deemed to be an "affiliate" of the Company, as the term "affiliate" is
(i) defined for purposes of paragraphs (c) and (d) of Rule 145 of the Rules and
Regulations (the "Rules and

Regulations") of the Securities and Exchange Commission (the "Commission") under
the Securities Act of 1933, as amended (the "Act"), and/or (ii) used in and for
purposes of Accounting Series Releases 130 and 135, as amended, and Staff
Accounting Bulletins 65 and 76 of the Commission.

          The undersigned understands that the representations, warranties and
covenants set forth herein will be relied upon by Parent, shareholders of
Parent, the Company, other shareholders of the Company and their respective
counsel and accountants.

          The undersigned represents and warrants to and agrees with Parent
that:

          1.   The undersigned has full power to execute and deliver this
Affiliate Agreement and to make the representations and warranties herein and to
perform its obligations hereunder.

          2.   The undersigned has carefully read this letter and the Agreement
and discussed its requirements and other applicable limitations upon its ability
to sell, transfer or otherwise dispose of Parent Common Stock and Exchangeable
Shares to the extent the undersigned felt necessary, with its counsel or counsel
for the Company.

          3.   The undersigned shall not make any sale, transfer or other
disposition of Parent Common Stock or Exchangeable Shares in violation of the
Act or the Rules and Regulations.

          4.   The undersigned has been advised that the issuance of shares of
Parent Common Stock and the Exchangeable Shares to the undersigned in connection
with the Arrangement has been or will be registered with the Commission under
the Act on a Registration Statement on Form S-4 or will be exempt from
registration under the Act pursuant to Section 3(a)(10) thereunder.  However,
the undersigned has also been advised that, since at the time the Arrangement
was submitted for a vote of the shareholders of the Company the undersigned may
be deemed to have been an affiliate of the Company and the distribution by the
undersigned of any Parent Common Stock or Exchangeable Shares has not been
registered, and is not exempt, under the Act, the undersigned may not sell,
transfer or otherwise dispose of Parent Common Stock or Exchangeable Shares
issued to the undersigned in the Arrangement (or obtained upon exchange or
conversion of the Exchangeable Shares for Parent Common Stock) unless (i) such
sale, transfer or other disposition has been registered under the Act, (ii) such
sale, transfer or other disposition is made in conformity with the requirements
of Rule 145 promulgated by the Commission under the Act, or (iii) in the opinion
of counsel reasonably acceptable to Parent, such sale, transfer or other
disposition is otherwise exempt from registration under the Act.

          5.   Parent or the amalgamated corporation, as the case may be, is
under no obligation to register the sale, transfer or other disposition of
Parent Common Stock or Exchangeable Shares by the undersigned or on its behalf
under the Act or to take any other

                                       B-2

<PAGE>

action necessary in order to make compliance with an exemption from such
registration available.

          6.   The undersigned acknowledges and agrees that stop transfer
instructions will be given to Parent's and the Company's  transfer agents with
respect to the Parent Common Stock and the Exchangeable Shares and there will be
placed on the certificates for the Parent Common Stock and the Exchangeable
Shares issued to the undersigned, or any substitutions therefor, a legend
stating in substance:

          "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A
     TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933
     APPLIES.  THE SHARES REPRESENTED BY THIS CERTIFICATE OR INTO WHICH THESE
     SHARES ARE EXCHANGEABLE MAY ONLY BE TRANSFERRED IN ACCORDANCE WITH THE
     TERMS OF AN AGREEMENT DATED __________, 1995 BETWEEN THE REGISTERED HOLDER
     HEREOF AND SILICON GRAPHICS, INC., A COPY OF WHICH AGREEMENT IS ON FILE AT
     THE PRINCIPAL OFFICES OF SILICON GRAPHICS, INC."

          7.   Unless the transfer by the undersigned of its Parent Common Stock
or Exchangeable Shares has been registered under the Act or is a sale made in
conformity with the provisions of Rule 145, Parent and the amalgamated
corporation reserve the right to put the following legend on the certificates
issued any transferee of the undersigned:

          "THE SHARES REPRESENTED BY THIS CERTIFICATE OR INTO WHICH THESE SHARES
     ARE EXCHANGEABLE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933
     AND WERE ACQUIRED FROM A PERSON WHO RECEIVED SUCH SHARES IN A TRANSACTION
     TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933 APPLIES.
     THE SHARES AND ANY SHARES INTO WHICH THIS CERTIFICATE IS EXCHANGEABLE HAVE
     BEEN ACQUIRED BY THE HOLDER NOT WITH A VIEW TO, OR FOR RESALE IN CONNECTION
     WITH, ANY DISTRIBUTION THEREOF WITHIN THE MEANING OF THE SECURITIES ACT OF
     1933 AND MAY NOT BE SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN
     ACCORDANCE WITH AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE
     SECURITIES ACT OF 1933."

          8.   The legends set forth in paragraphs 6 and 7 above shall be
removed by delivery of substitute certificates without such legend if the
undersigned shall have delivered to Parent and the amalgamated corporation a
copy of a letter from the staff of the Commission, or an opinion of counsel in
form and substance reasonably satisfactory to

                                       B-3

          (a)  any shares of Parent Common Stock or Exchangeable Shares which
     the undersigned may acquire in connection with the Arrangement, or any
     securities which may be paid as a dividend or otherwise distributed thereon
     or with respect thereto or issued or delivered in exchange or substitution

outstanding, the Parent (and Swissco in the case of subclauses (b), (e) and (f))

<PAGE>

     will have sufficient assets, funds and other property available to enable

     applicable law, of an equivalent dividend on the Exchangeable Shares and
     (ii) the Corporation shall simultaneously declare or pay, as the case may
     be, an equivalent dividend on the Exchangeable Shares, in each case in
     accordance with the Share Provisions;

          (b) cause the Corporation to declare simultaneously with the
     declaration of any dividend on the Parent Common Shares an equivalent
     dividend on the Exchangeable Shares and, when such dividend is paid on the
     Parent Common Shares, cause the Corporation to pay simultaneously therewith
     such equivalent dividend on the Exchangeable Shares, in each case in
     accordance with the Share Provisions;

          (c) advise the Corporation sufficiently in advance of the declaration
     by the Parent of any dividend on the Parent Common Shares and take all such
     other actions as are necessary, in cooperation with the Corporation, to
     ensure that the respective declaration date, record date and payment date
     for a dividend on the Exchangeable Shares shall be the same as the record
     date, declaration date and payment date for the corresponding dividend on
     the Parent Common Shares;

          (d) ensure that the record date for any dividend declared on the
     Parent Common Shares is not less than 10 Business Days after the
     declaration date for such dividend;

          (e) take all such actions and do all such things as are necessary or
     desirable to enable and permit the Corporation, in accordance with
     applicable law, to pay and otherwise perform its obligations with respect

     outstanding Exchangeable Share upon the liquidation, dissolution or
     winding-up of the Corporation, including without limitation all such
     actions and all such things as are necessary or desirable to enable and
     permit the Corporation to cause to be delivered Parent Common Shares to the
     holders of Exchangeable Shares in accordance with the provisions of Article
     5 of the Share Provisions; and

     delivered Parent Common Shares to the holders of Exchangeable Shares, upon
     the redemption of the Exchangeable Shares in accordance with the provisions
     of Article 6 or Article 7 of the Share Provisions, as the case may be.

     2.2 SEGREGATION OF FUNDS.  The Corporation will deposit a sufficient amount
of such funds in a separate account and segregate a sufficient amount of such
assets and other property as is necessary to enable the Corporation to pay or
otherwise satisfy the applicable Liquidation Amount, Retraction Price or
Redemption Price, in each case for the benefit of holders from time to time of
the Exchangeable Shares, and will use such funds, assets and other property so
segregated exclusively for the payment or other satisfaction of the Liquidation
Amount, the Retraction Price or the Redemption Price, as applicable.

     2.3 RESERVATION OF PARENT COMMON SHARES. The Parent hereby represents,
warrants and covenants that it has irrevocably reserved for issuance and will at
all times keep available, free from preemptive and other rights, out of its
authorized and unissued capital stock such number of Parent Common Shares (or
other shares or securities into which the Parent Common Shares may be
reclassified or changed as contemplated by section 2.7 hereof) (a) as is equal
to the sum of (i) the number of Exchangeable Shares issued and outstanding from
time to time and (ii) the number of Exchangeable Shares issuable upon the
exercise of all rights to acquire Exchangeable Shares outstanding from time to
time and (b) as are now and may hereafter be required to enable and permit the
Corporation to meet its obligations hereunder, under the Voting and Exchange
Trust Agreement,


                                       C-3

<PAGE>

under the Share Provisions and under any other security or commitment pursuant
to which the Parent may now or hereafter be required to issue Parent Common
Shares.

     2.4 NOTIFICATION OF CERTAIN EVENTS. In order to assist the Parent and
Swissco to comply with their obligations hereunder, the Corporation will give
the Parent and Swissco notice of each of the following events at the time set
forth below:

          (a) in the event of any determination by the Board of Directors of the
     Corporation to institute voluntary liquidation, dissolution or winding up
     proceedings with respect to the Corporation or to effect any other
     distribution of the assets of the Corporation among its shareholders for
     the purpose of winding up its affairs, at least 60 days prior to the
     proposed effective date of such liquidation, dissolution, winding up or
     other distribution;

          (b) immediately, upon the earlier of receipt by the Corporation of
     notice of and the Corporation otherwise becoming aware of any threatened or
     instituted claim, suit, petition or other proceedings with respect to the
     involuntary liquidation, dissolution or winding up of the Corporation or to
     effect any other distribution of the assets of the Corporation among its
     shareholders for the purpose of winding up its affairs;

          (c) immediately, upon receipt by the Corporation of a Retraction
     Request (as defined in the Share Provisions);

          (d) at least 130 days prior to any accelerated Automatic Redemption
     Date determined by the Board of Directors of the Corporation in accordance
     with the Share Provisions; and

          (e) as soon as practicable upon the issuance by the Corporation of any
     Exchangeable Shares or rights to acquire Exchangeable Shares (other than
     the issuance of Exchangeable Shares upon the conversion of outstanding
     Class B non-voting common shares pursuant to the Arrangement).

     2.5 DELIVERY OF PARENT COMMON SHARES. In furtherance of its obligations
under sections 2.1(e) and 2.1(f) hereof, upon notice from the Corporation of any
event which requires the Corporation to cause to be delivered Parent Common
Shares to any holder of Exchangeable Shares, Swissco shall forthwith deliver the
requisite Parent Common Shares to or to the order of the former holder of the
surrendered Exchangeable Shares, as the Corporation shall direct. All such
Parent Common Shares shall be duly issued as fully paid and non-assessable and
shall be free and clear of any lien, claim or encumbrance. In consideration of
the delivery of each such Parent Common Share by Swissco, the Corporation shall
issue to Swissco, or as Swissco shall direct, such number of Class A Common
Shares of the Corporation as is equal to the fair value of such Parent Common
Share.

     2.6 QUALIFICATION OF PARENT COMMON SHARES.  The Parent represents and
warrants that it has taken all actions and done all things as are necessary or
desirable to cause the Parent Common Shares to be issued and delivered pursuant
to the Share Provisions, the Exchange Right or the Automatic Exchange Rights to
be freely tradeable thereafter (other than any restrictions on transfers by
reason of a holder being a "control person" of the Parent for purposes of
Canadian federal or provincial securities law or an "affiliate" of the Parent
or, prior to the Effective Date, Alias Research Inc. for purposes of United
States federal or state securities law).  The Parent will in good faith
expeditiously take all such actions and do all such things as are necessary or
desirable to cause all Parent Common Shares to be delivered pursuant to the
Share Provisions, the Exchange Right or the Automatic Exchange Rights (as
defined in the Voting and Exchange Trust Agreement) to be listed, quoted or
posted for trading on all stock exchanges and quotation systems on which
outstanding Parent Common Shares are listed, quoted or posted for trading at
such time.

     an amalgamation, merger, reorganization or other transaction affecting the
     Parent Common Shares;

unless (i) the Corporation is able under applicable law to simultaneously make
the same or an economically equivalent change to, or in the rights of the
holders of, the Exchangeable Shares, and (ii) the Corporation simultaneously
does make the same or an economically equivalent change to, or in the rights of
the holders of, the Exchangeable Shares; provided that, for greater certainty,
the above restrictions shall not apply to any action taken by the Parent in
order to give effect to and to consummate the Other Merger Agreement, in the
manner contemplated by, and in accordance with, the Other Merger Agreement.

     (c) The Parent will ensure that the record date for any event referred to
in section 2.7(a) or 2.7(b)

                                       C-5

<PAGE>

above, or (if no record date is applicable for such event) the effective date
for any such event, is not less than 20 Business Days after the date on which
such event is declared or announced by the Parent (with simultaneous notice
thereof to be given by the Parent to the Corporation).

     (d) The Board of Directors of the Corporation shall determine, in good
faith and in its sole discretion (with the assistance of such reputable and
qualified independent financial advisors and/or other experts as the board may
require), economic equivalence for the purposes of any event referred to in
section 2.7(a) or 2.7(b) above and each such determination shall be conclusive
and binding on Swissco and the Parent. In making each such determination, the
following factors shall, without excluding other factors determined by the board
to be relevant, be considered by the Board of Directors of the Corporation:

        (i) in the case of any stock dividend or other distribution payable in
      Parent Common Shares, the number of such shares issued in proportion to
      the number of Parent Common Shares previously outstanding;

        (ii) in the case of the issuance or distribution of any rights, options
      or warrants to subscribe for or purchase Parent Common Shares (or
      securities exchangeable for or convertible into or carrying rights to
      acquire Parent Common Shares), the relationship between the exercise
      price of each such right, option or warrant and the current market value
      (as determined by the Board of Directors of the Corporation in the manner
      above contemplated) of a Parent Common Share;

        (iii) in the case of the issuance or distribution of any other form of
      property (including without limitation any shares or securities of the
      Parent of any class other than Parent Common Shares, any rights, options
      or warrants other than those referred to in section 2.7(d)(ii) above, any
      evidences of indebtedness of the Parent or any assets of the Parent), the
      relationship between the fair market value (as determined by the Board of
      Directors of the Corporation in the manner above contemplated) of such
      property to be issued or distributed with respect to each outstanding
      Parent Common Share and the current market value (as determined by the
      Board of Directors of the Corporation in the manner above contemplated)
      of a Parent Common Share; and

        (iv) in the case of any subdivision, redivision or change of the then
      outstanding Parent Common Shares into a greater number of Parent Common
      Shares or the reduction, combination or consolidation or change of the
      then outstanding Parent Common Shares into a lesser number of Parent
      Common Shares or any amalgamation, merger, reorganization or other
      transaction affecting the Parent Common Shares, the effect thereof upon
      the then outstanding Parent Common Shares.

      For purposes of the foregoing determinations, the current market value of
any security listed and traded or quoted on a securities exchange shall be the
average of the closing prices of such security during the 3 consecutive trading
days ending not more than five trading days before the date of determination on
the principal securities exchange on which such securities are listed and traded
or quoted; provided, however, that if there is no public distribution or trading
activity of such securities during such period, then the current market value
thereof shall be determined by the Board of Directors of the Corporation, in
good faith and in its sole discretion (with the assistance of such reputable and
qualified independent financial advisors and/or other experts as the board may
require), and provided further that any such determination by the board shall be
conclusive and binding on the Parent.

     2.8 TENDER OFFERS, ETC. In the event that a tender offer, share exchange
offer, issuer bid, take-over bid or similar transaction with respect to Parent
Common Shares (an "Offer") is proposed by the Parent or is proposed to the
Parent or its shareholders and is recommended by the Board of Directors of the
Parent, or is otherwise effected or to be effected with the consent or approval
of the Board of Directors of the Parent, the Parent will use its best efforts
expeditiously and in good faith to take all such actions and do all such things
as

                                       C-6

<PAGE>

are necessary or desirable to enable and permit holders of Exchangeable
Shares to participate in such Offer to the same extent and on an economically
equivalent basis as the holders of Parent Common Shares, without discrimination.
Without limiting the generality of the foregoing, the Parent will use its best
efforts expeditiously and in good faith to ensure that holders of Exchangeable
Shares may participate in all such Offers without being required to retract
Exchangeable Shares as against the Corporation (or, if so required, to ensure
that any such retraction shall be effective only upon, and shall be conditional
upon, the closing of the Offer and only to the extent necessary to tender or
deposit to the Offer).

     2.9 OWNERSHIP OF OUTSTANDING SHARES. Without the prior approval of the
Corporation and the prior approval of the holders of the Exchangeable Shares
given in accordance with Section 10.2 of the Share Provisions, the Parent
covenants and agrees in favour of the Corporation that, as long as any
outstanding Exchangeable Shares are owned by any person or entity other than the
Parent or any of its Affiliates, Parent will be and remain the direct or
indirect beneficial owner of all issued and outstanding shares in the capital of
the Corporation and all outstanding securities of the Corporation carrying or
otherwise entitled to voting rights in any circumstances, in each case other
than the Exchangeable Shares.

     2.10 PARENT NOT TO VOTE EXCHANGEABLE SHARES. The Parent covenants and
agrees that it will appoint and cause to be appointed proxyholders with respect
to all Exchangeable Shares held by the Parent and its subsidiaries and
Affiliates for the sole purpose of attending each meeting of holders of
Exchangeable Shares in order to be counted as part of the quorum for each such
meeting. The Parent further covenants and agrees that it will not, and will
cause its subsidiaries and Affiliates not to, exercise any voting rights which
may be exercisable by holders of Exchangeable Shares from time to time pursuant
to the Share Provisions or pursuant to the provisions of the BUSINESS
CORPORATIONS ACT (Ontario) (or any successor or other corporate statute by which
the Corporation may in the future be governed) with respect to any Exchangeable
Shares held by it or by its subsidiaries or Affiliates in respect of any matter
considered at any meeting of holders of Exchangeable Shares.

     2.11 DUE PERFORMANCE.  On and after the Effective Date, Parent and Swissco
shall duly and timely perform all of their respective obligations expressed in
the Plan of Arrangement.

     3.1 TERM. This agreement shall come into force and be effective upon the
issue by the Corporation of Exchangeable Shares under the Agreement and shall
terminate and be of no further force and effect at such time as no Exchangeable
Shares (or securities or rights convertible into or exchangeable for or carrying
rights to acquire Exchangeable Shares) are held by any party other than the
Parent and any of its Affiliates.

     3.2 CHANGES IN CAPITAL OF PARENT AND THE CORPORATION.  Notwithstanding the
provisions of section 3.4, at all times after the occurrence of any event
effected pursuant to section 2.7 or 2.8 hereof, as a result of which either the
Parent Common Shares or the Exchangeable Shares or both are in any way changed,
this agreement shall forthwith be amended and modified as necessary in order
that it shall apply with full force and effect, MUTATIS MUTANDIS, to all new
securities into which the Parent Common Shares or the Exchangeable Shares or
both are so changed and the parties hereto shall execute and deliver an
agreement in writing giving effect to and evidencing such necessary amendments
and modifications.

     3.3 SEVERABILITY. If any provision of this agreement is held to be invalid,
illegal or unenforceable, the validity, legality or enforceability of the
remainder of this agreement shall not in any way be affected or impaired thereby
and this agreement shall be carried out as nearly as possible in accordance with
its original terms and conditions.

        (c) making such changes or corrections which, on the advice of counsel

     the opinion that such changes or corrections will not be prejudicial to the
     interests of the holders of the Exchangeable Shares.

     3.6 MEETING TO CONSIDER AMENDMENTS. The Corporation, at the request of the

Parent, Swissco and the Corporation of its receipt of the same, which notice to
the Parent, Swissco and the Corporation shall constitute exercise of the

Shares, and Swissco shall immediately thereafter deliver or cause to be
delivered to the Trustee, for delivery to the Beneficiary of such Exchangeable
Shares (or to such other persons. if any, properly designated by such
Beneficiary), the certificates for the number of Parent Common Shares
deliverable in connection with the exercise of the Exchange Right, which shares
shall be duly issued as fully paid and non-assessable and shall be free and
clear of any lien, claim or encumbrance, and cheques for the balance, if any, of
the total purchase price therefor.  Immediately upon the giving of notice by the
Trustee to the Parent, Swissco and the Corporation of the exercise of the
Exchange Right, as provided in this section 5.6, the closing of the transaction
of purchase and sale contemplated by the Exchange Right shall be deemed to have
occurred, and the Beneficiary of such Exchangeable Shares shall be deemed to
have transferred  to Swissco all of its right, title and interest in and to such
Exchangeable Shares and in the related interest in the Trust Estate and shall
cease to be a holder of such Exchangeable Shares and shall not be entitled to
exercise any of the rights of a holder in respect thereof, other than the right
to receive his proportionate part of the total purchase price therefor, unless
the requisite number of Parent Common Shares (together with a cheque for the
balance, if any, of the total purchase price therefor) is not allotted, issued
and delivered by Swissco to the Trustee, for delivery to such Beneficiary (or to
such other persons, if any, properly designated by such Beneficiary), within
five Business Days of the date of the giving of such notice by the Trustee, in
which case

                                      D-10

Shares are so allotted, issued and delivered by Swissco and any such cheque is
so delivered and paid. Concurrently with such Beneficiary ceasing to be a holder
of Exchangeable Shares, the Beneficiary shall be considered and deemed for all
purposes to be the holder of the Parent Common Shares delivered to it pursuant
to the Exchange Right.

     5.7  EXERCISE OF EXCHANGE RIGHT SUBSEQUENT TO RETRACTION.  In the event

notified by the Corporation pursuant to Section 6.6 of the Exchangeable Shares
Provisions that the Corporation will not be permitted as a result of solvency
requirements of applicable law to redeem all such Retracted Shares, and provided
that Swissco shall not have exercised the Retraction Call Right with respect to
the Retracted Shares and that the Beneficiary has not revoked the retraction
request delivered by the Beneficiary to the Corporation pursuant to Section 6.1
of the Exchangeable Share Provisions, the retraction request will constitute and
will be deemed to constitute notice from the Beneficiary to the Trustee
instructing the Trustee to exercise the Exchange Right with respect to those
Retracted Shares which the Corporation is unable to redeem.  In any such event,

immediately to notify the Trustee of such prohibition against the Corporation
redeeming all of the Retracted Shares and immediately to forward or cause to be
forwarded to the Trustee all relevant materials delivered by the Beneficiary to
the Corporation or to the transfer agent of the Exchangeable Shares (including
without limitation a copy of the retraction request delivered pursuant to
Section 6.1 of the Exchangeable Share Provisions) in connection with such
proposed redemption of the Retracted Shares and the Trustee will thereupon
exercise the Exchange Right with respect to the Retracted Shares that the
Corporation is not permitted to redeem and will require the Parent to purchase
such shares in accordance with the provisions of this Article 5.

to Swissco pursuant to the Exchange Right or the Automatic Exchange Rights, the

delivered in connection with the payment of the total purchase price therefor
shall be issued in the name of the Beneficiary of the Exchangeable Shares so
sold or in such names as such Beneficiary may otherwise direct in writing
without charge to the holder of the Exchangeable Shares so sold; provided,
however, that such Beneficiary (a) shall pay (and neither the Parent, Swissco,
the Corporation nor the Trustee shall be required to pay) any documentary,
stamp, transfer or other taxes that may be payable in respect of any transfer
involved in the issuance or delivery of such shares to a person other than such
Beneficiary or (b) shall have established to the satisfaction of the Trustee,

time or both would be an Insolvency Event, the Corporation, Swissco and the
Parent shall give written notice thereof to the Trustee.  As soon as practicable
after receiving notice from the Corporation, Swissco and the Parent or from any
other person of the occurrence of an Insolvency Event, the Trustee will mail to
each Beneficiary, at the expense of Swissco, a notice of such Insolvency Event,
which notice shall contain a brief statement of the right of the Beneficiaries
with respect to the Exchange Right.

     5.10  QUALIFICATION  OF PARENT COMMON SHARES. The Parent represents and
warrants that it has taken all actions and done all things as are necessary or
desirable to cause the Parent Common Shares to be issued and delivered pursuant
to the Exchangeable Share Provisions, the Exchange Right or the Automatic
Exchange Rights to be freely tradeable thereafter (other than any restrictions
on transfers by reason of a holder being a "control person" of the Parent for
purposes of Canadian federal or provincial securities law or an "affiliate" of
the Parent or, prior to the Effective Date, Alias Research Inc. for purposes of
United States federal or state securities law).  The Parent will in good faith
expeditiously take all such actions and do all such things as are necessary or
desirable to cause all Parent Common Shares to be delivered pursuant to the
Exchangeable Share Provisions, the Exchange Right or the Automatic Exchange
Rights to be listed, quoted or posted for trading on all stock exchanges and
quotation systems on which outstanding Parent

                                      D-11

<PAGE>

Common Shares are listed, quoted or posted for trading at such time.

     5.11  RESERVATION OF PARENT COMMON SHARES.

     The Parent hereby represents, warrants and covenants that it has
irrevocably reserved for issuance and will at all times keep available, free
from preemptive and other rights, out of its authorized and unissued capital
stock such number of Parent Common Shares (a) as is equal to the sum of (i) the
number of Exchangeable Shares issued and outstanding from time to time and (ii)
the number of Exchangeable Shares issuable upon the exercise of all rights to
acquire Exchangeable Shares outstanding from time to time and (b) as are now and
may hereafter be required to enable and permit the Corporation and Swissco to
meet their respective obligations hereunder, under the Support Agreement, under
the Exchangeable Share Provisions and under any other security or commitment
pursuant to which the Parent may now or hereafter be required to issue Parent
Common Shares.

     5.12 AUTOMATIC EXCHANGE ON LIQUIDATION OF PARENT.

          (a) The Parent will give the Trustee notice of each of the following
     events at the time set forth below:

               (i)  in the event of any determination by the Board of Directors
          of the Parent to institute voluntary liquidation, dissolution or
          winding-up proceedings with respect to the Parent or to effect any
          other distribution of assets of the Parent among its shareholders for
          the purpose of winding up its affairs, at least 60 days prior to the
          proposed effective date of such liquidation, dissolution, winding-up
          or other distribution; and

               (ii)  immediately, upon the earlier of (A) receipt by the Parent
          of notice of and (B) the Parent otherwise becoming aware of any
          threatened or instituted claim, suit, petition or other proceedings
          with respect to the involuntary liquidation, dissolution or winding-up
          of the Parent or to effect any other distribution of assets of the
          Parent among its shareholders for the purpose of winding up its
          affairs.

          (b) immediately following receipt by the Trustee from the Parent of
     notice of any event (a "Liquidation Event") contemplated by section
     5.12(a)(i) or 5.12(a)(ii) above, the Trustee will give notice thereof to
     the Beneficiaries.  Such notice shall include a brief description of the
     automatic exchange of Exchangeable Shares for Parent Common Shares provided
     for in section 5.12(c).

          (c) In order that the Beneficiaries will be able to participate on a
     pro rata basis with the holders of Parent Common Shares in the distribution
     of assets of the Parent in connection with a Liquidation Event, on the
     fifth Business Day prior to the effective date (the "Liquidation Event
     Effective Date") of a Liquidation Event all of the then outstanding
     Exchangeable Shares shall be automatically exchanged for Parent Common
     Shares. To effect such automatic exchange, Swissco shall purchase each
     Exchangeable Share outstanding on the fifth Business Day prior to the
     Liquidation Event Effective Date and held by Beneficiaries, and each
     Beneficiary shall sell the Exchangeable Shares held by it at such time, for
     a purchase price per share equal to (a) the Current Market Price of a
     Parent Common Share on the fifth Business Day prior to the Liquidation
     Event Effective Date, which shall be satisfied in full by Swissco
     delivering or causing to be delivered to the Beneficiary one Parent Common
     Share, plus (b) an additional amount equivalent to the full amount of all
     dividends declared and unpaid on each such Exchangeable Share and all
     dividends declared on Parent Common Shares which have not been declared on
     such Exchangeable Shares in accordance with Section 3.1 of the Exchangeable
     Share Provisions (provided that if the record date for any such declared
     and unpaid dividends occurs on or after the day of closing of such purchase
     and sale the purchase price shall not include such additional amount
     equivalent to such declared and unpaid dividends).  In connection with such
     automatic exchange, the Parent will provide to the Trustee an Officer's
     Certificate setting forth the

                                      D-12

<PAGE>

calculation of the purchase price for each Exchangeable Share.

          (d) On the fifth Business Day prior to the Liquidation Event Effective
     Date, the closing of the transaction of purchase and sale contemplated by
     the automatic exchange of Exchangeable Shares for Parent Common Shares
     shall be deemed to have occurred, and each Beneficiary shall be deemed to
     have transferred to Swissco all of the Beneficiary's right, title and
     interest in and to its Exchangeable Shares and the related interest in the
     Trust Estate and shall cease to be a holder of such Exchangeable Shares and
     Swissco shall deliver or cause to be delivered to the Beneficiary the
     Parent Common Shares deliverable upon the automatic exchange of
     Exchangeable Shares for Parent Common Shares and shall deliver to the
     Trustee for delivery to the Beneficiary a cheque for the balance, if any,
     of the total purchase price for such Exchangeable Shares. Concurrently with
     such Beneficiary ceasing to be a holder of Exchangeable Shares, the
     Beneficiary shall be considered and deemed for all purposes to be the
     holder of the Parent Common Shares issued to it pursuant to the automatic
     exchange of Exchangeable Shares for Parent Common Shares and the
     certificates held by the Beneficiary previously representing the
     Exchangeable Shares exchanged by the Beneficiary with Swissco pursuant to
     such automatic exchange shall thereafter be deemed to represent the Parent
     Common Shares delivered to the Beneficiary by Swissco pursuant to such
     automatic exchange. Upon the request of a Beneficiary and the surrender by
     the Beneficiary of Exchangeable Share certificates deemed to represent
     Parent Common Shares, duly endorsed in blank and accompanied by such
     instruments of transfer as Swissco may reasonably require, Swissco shall
     deliver or cause to be delivered to the Beneficiary certificates
     representing the Parent Common Shares of which the Beneficiary is the
     holder.

     5.13 WITHHOLDING RIGHTS.  Parent, Swissco and the Trustee shall be entitled
to deduct and withhold from the consideration otherwise payable pursuant to this
Agreement to any holder of Exchangeable Shares such amounts as Parent, Swissco
or the Trustee is required or permitted to deduct and withhold with respect to
the making of such payment under the United States Internal Revenue Code of
1986, as amended (the "Code"), the Income Tax Act (Canada) (the "Canadian Code")
or any provision of state, local, provincial or foreign tax law. To the extent
that amounts are so withheld, such withheld amounts shall be treated for all
purposes of this Agreement as having been paid to the holder of the shares in
respect of which such deduction and withholding was made, provided that such
withheld amounts are actually remitted to the appropriate taxing authority.  To
the extent that the amount so required or permitted to be deducted or withheld
from any payment to a holder exceeds the cash portion of the consideration
otherwise payable to the holder, the Parent, Swissco or the Trustee is hereby
authorized to sell or otherwise dispose of at fair market value such portion of
the consideration as is necessary to provide sufficient funds to the Parent,
Swissco or the Trustee, as the case may be, in order to enable it to comply with
such deduction or withholding requirement and shall account to the relevant
holder for any balance of such sale proceeds.

                             CONCERNING THE TRUSTEE

     7.1 POWERS AND DUTIES OF THE TRUSTEE.  The rights, powers and authorities
of the Trustee under this trust agreement, in its capacity as trustee of the
Trust, shall include:

          (a) purchasing the Voting Share from the Parent as trustee for and on
     behalf of the Beneficiaries in accordance with the provisions of this
     agreement;

                                      D-13

<PAGE>

          (b) granting proxies and distributing materials to Beneficiaries as
     provided in this trust agreement;

          (c) voting the Beneficiary Votes in accordance with the provisions of

          (d) receiving the grant of the Exchange Right and the Automatic
     Exchange Rights from Swissco as trustee for and on behalf of the
     Beneficiaries in accordance with the provisions of this trust agreement;

          (e) exercising the Exchange Right and enforcing the benefit of the
     Automatic Exchange Rights, in each case in accordance with the provisions
     of this trust agreement, and in connection therewith receiving from
     Beneficiaries Exchangeable Shares and other requisite documents and
     distributing to such Beneficiaries the Parent Common Shares and cheques, if
     any, to which such Beneficiaries are entitled upon the exercise of the
     Exchange Right or pursuant to the Automatic Exchange Rights, as the case
     may be;

          (f) holding title to the Trust Estate;

          (g) investing any moneys forming, from time to time, a part of the
     Trust Estate as provided in this trust agreement;

          (h) taking action on its own initiative or at the direction of a
     Beneficiary or Beneficiaries to enforce the obligations of the Parent and
     Swissco under this trust agreement; and

          (i) taking such other actions and doing such other things as are
     specifically provided in this trust agreement.

     In the exercise of such rights, powers and authorities the Trustee shall
have (and is granted) such incidental and additional rights, powers and
authority not in conflict with any of the provisions of this trust agreement as
the Trustee, acting in good faith and in the reasonable exercise of its
discretion, may deem necessary, appropriate or desirable to effect the purpose
of the Trust.  Any exercise of such discretionary rights, powers and authorities
by the Trustee shall be final, conclusive and binding upon all persons.  For
greater certainty, the Trustee shall have only those duties as are set out
specifically in this trust agreement.

     The Trustee in exercising its rights, powers, duties and authorities
hereunder shall act honestly and in good faith with a view to the best interests
of the Beneficiaries and shall exercise the care, diligence and skill that a
reasonably prudent trustee would exercise in comparable circumstances.

     7.2  NO CONFLICT OF INTEREST.  The Trustee represents to the Corporation,
Swissco and the Parent that at the date of execution and delivery of this trust
agreement there exists no material conflict of interest in the role of the
Trustee as a fiduciary hereunder and the role of the Trustee in any other
capacity. The Trustee shall, within 90 days after it becomes aware that such a
material conflict of interest exists, either eliminate such material conflict of
interest or resign in the manner and with the effect specified in Article 10.
If, notwithstanding the foregoing provisions of this section 7.2, the Trustee
has such a material conflict of interest, the validity and enforceability of
this trust agreement shall not be affected in any manner whatsoever by reason
only of the existence of such material conflict of interest. If the Trustee
contravenes the foregoing provisions of this section 7.2, any interested party
may apply to the Ontario Court of Justice (General Division) for an order that
the Trustee be replaced as trustee hereunder.

     7.3  DEALINGS WITH TRANSFER AGENTS, REGISTRARS, ETC.   The Corporation,
Swissco and the Parent irrevocably authorize the Trustee, from time to time, to:

          (a) consult, communicate and otherwise deal with the respective
     registrars and transfer agents,

                                      D-14

     Exchangeable Shares and the Parent Common Shares; and

          (b) requisition, from time to time, (i) from any such registrar or
     transfer agent any information readily available from the records
     maintained by it which the Trustee may reasonably require for the discharge
     of its duties and responsibilities under this trust agreement and (ii) from
     the transfer agent of the Parent Common Shares, and any subsequent transfer
     agent of such shares, the share certificates issuable upon the exercise
     from time to time of the Exchange Right and pursuant to the automatic
     exchange of Exchangeable Shares for Parent Common Shares in the manner
     specified in Article 5 hereof.

The Corporation, Swissco and the Parent irrevocably authorize their respective
registrars and transfer agents to comply with all such requests.  The Parent and
Swissco covenant that they will supply the Parent's transfer agent with duly
executed share certificates for the purpose of completing the exercise from time
to time of the Exchange Right and the automatic exchange of Exchangeable Shares
for Parent Common Shares, in each case pursuant to Article 5 hereof.

     7.4 BOOKS AND RECORDS.  The Trustee shall keep available for inspection by
the Parent, Swissco and the Corporation, at the Trustee's principal corporate
trust office in Toronto, Ontario, correct and complete books and records of
account relating to the Trustee's actions under this trust agreement, including
without limitation all information relating to mailings and instructions to and
from Beneficiaries and all transactions pursuant to the Exchange Right and the
Automatic Exchange Rights. On or before March 31, 1996, and on or before March
31 in every year thereafter, so long as the Voting Share is on deposit with the
Trustee, the Trustee shall transmit to the Parent, Swissco and the Corporation a

     ended on such date; and

          (c) all other actions taken by the Trustee in the performance of its
     duties under this trust agreement which it had not previously reported.


     7.5  INCOME TAX RETURNS AND REPORTS.  The Trustee shall, to the extent
necessary, prepare and file on behalf of the Trust appropriate United States and
Canadian income tax returns and any other returns or reports as may be required
by applicable law or pursuant to the rules and regulations of any securities
exchange and without limiting the generality of section 7.10 hereof or other
trading system through which the Exchangeable Shares are traded and, in
connection therewith, may obtain the advice and assistance of such experts as
the Trustee may consider necessary or advisable.

     7.6  INDEMNIFICATION PRIOR TO CERTAIN ACTIONS BY TRUSTEE.  The Trustee
shall exercise any or all of the rights, duties, powers or authorities vested in
it by this trust agreement at the request, order or direction of any Beneficiary

indemnity against the costs, expenses and liabilities which may be incurred by
the Trustee therein or thereby, provided that no Beneficiary shall be obligated
to furnish to the Trustee any such funding, security or indemnity in connection
with the exercise by the Trustee of any of its rights, duties, powers and
authorities with respect to the Voting Share pursuant to Article 4 hereof,
subject to section 7. l 5, and with respect to the Exchange Right pursuant to
Article 5 hereof, subject to section 7.15, and with respect to the Automatic
Exchange Rights pursuant to Article 5 hereof.

Trustee to expend or risk its own funds or otherwise incur financial liability
in the exercise of any of its rights, powers, duties or authorities unless
funded, given security and indemnified as aforesaid.

     7.7  ACTIONS BY BENEFICIARIES.  No Beneficiary shall have the right to
institute any action, suit or proceeding or to exercise any other remedy
authorized by this trust agreement for the purpose of enforcing any of its
rights or for the execution of any trust or power hereunder unless the
Beneficiary has requested the Trustee to take or institute such action, suit or
proceeding and furnished the Trustee with the funding, security and indemnity
referred to in section 7.6 and the Trustee shall have failed to act within a
reasonable time thereafter. In such case, but not otherwise, the Beneficiary
shall be entitled to take proceedings in any court of competent jurisdiction
such as the Trustee might have taken; it being understood and intended that no
one or more Beneficiaries shall have any right in any manner whatsoever to
affect, disturb or prejudice the rights hereby created by any such action, or to
enforce any right hereunder or under the Voting Rights, the Exchange Rights or
the Automatic Exchange Rights except subject to the conditions and in the manner
herein provided, and that all powers and trusts hereunder shall be exercised and

except only as herein provided, and in any event for the equal benefit of all
Beneficiaries.

in contravention of any of its rights, powers, duties and authorities hereunder
if, when required, it acts and relies in good faith upon lists, mailing labels,
notices, statutory declarations, certificates, opinions, reports or other papers
or documents furnished pursuant to the provisions hereof or required by the
Trustee to be furnished to it in the exercise of its rights, powers, duties and
authorities hereunder if such lists, mailing labels, notices, statutory
declarations, certificates, opinions, reports or other papers or documents
comply with the provisions of section 7.9 hereof, if applicable, and with any
other applicable provisions of this trust agreement.

the terms of this trust agreement may or ought to be invested or which may be on
deposit with the Trustee or which may be in the hands of the Trustee may be
invested and reinvested in the name or under the control of the Trustee in
securities in which, under the laws of the Province of Ontario, trustees are

shall so invest such moneys on the written direction of the Corporation. Pending
the investment of any moneys as hereinbefore provided, such moneys may be
deposited in the name of the Trustee in any chartered bank in Canada or, with

<PAGE>

business of a trust company in the Province of Ontario but if, notwithstanding

a trust company in the Province of Ontario, either become so authorized or
resign in the manner and with the effect specified in Article 10.

     7.15 CONFLICTING CLAIMS.  If conflicting claims or demands are made or
asserted with respect to any interest of any Beneficiary in any Exchangeable
Shares, including any disagreement between the heirs, representatives,
successors or assigns succeeding to all or any part of the interest of any
Beneficiary in any Exchangeable Shares resulting in conflicting claims or
demands being made in connection with such interest, then the Trustee shall be
entitled, at its sole discretion, to refuse to recognize or to comply with any
such claim or demand. In so refusing, the Trustee may elect not to exercise any
Voting Rights, Exchange Right or Automatic Exchange Rights subject to such
conflicting claims or demands and, in so doing, the Trustee shall not be or
become liable to any person on account of such election or its failure or
refusal to comply with any such conflicting claims or demands. The Trustee shall
be entitled to continue to refrain from acting and to refuse to act until:

          (a) the rights of all adverse claimants with respect to the Voting
     Rights, Exchange Right or Automatic Exchange Rights subject to such
     conflicting claims or demands have been adjudicated by a final judgment of
     a court of competent jurisdiction; or

     or Automatic Exchange Rights subject to such conflicting claims or demands
     have been conclusively settled by a valid written agreement binding on all
     such adverse claimants, and the Trustee shall have been furnished with an
     executed copy of such agreement.

If the Trustee elects to recognize any claim or comply with any demand made by
any such adverse claimant, it may in its discretion require such claimant to
furnish such surety bond or other security satisfactory to the Trustee as it
shall deem appropriate fully to indemnify it as between all conflicting claims
or demands.

     7.16  ACCEPTANCE OF TRUST.  The Trustee hereby accepts the Trust created
and provided for by and in this trust agreement and agrees to perform the same
upon the terms and conditions herein set forth and to hold all rights,
privileges and benefits conferred hereby and by law in trust for the various
persons who shall from time to time be Beneficiaries, subject to all the terms
and conditions herein set forth.

     9.1 INDEMNIFICATION OF THE TRUSTEE.  The Parent, Swissco and the
Corporation jointly and severally agree to indemnify and hold harmless the
Trustee and each of its directors, officers, employees and agents appointed and
acting in accordance with this trust agreement (collectively, the "Indemnified
Parties") against all claims, losses, damages, costs, penalties, fines and
reasonable expenses (including reasonable expenses of the Trustee's legal
counsel) which, without fraud, negligence, wilful misconduct or bad faith on the
part of such Indemnified Party, may be paid, incurred or suffered by the
Indemnified Party by reason of or as a result of the Trustee's acceptance or
administration of the Trust, its compliance with its duties set forth in this
trust agreement, or any written or oral instructions delivered to the Trustee by
the Parent, Swissco or the Corporation pursuant hereto. In no case shall the
Parent, Swissco or the Corporation be liable under this indemnity for any claim
against any of the Indemnified Parties unless the Parent, Swissco and the
Corporation shall be notified by the Trustee of the written assertion of a claim
or of any action commenced against the Indemnified Parties, promptly after any
of the Indemnified Parties shall have received any such written assertion of a
claim or shall have been served with a summons or other first legal process
giving information as to the nature and basis of the claim. Subject to (ii),
below, the Parent, Swissco and the Corporation shall be entitled to participate
at their own expense in the defence and, if the Parent, Swissco or the
Corporation so elect at any time after receipt of such notice, either of them
may assume the defence of any suit brought to enforce any such claim. The
Trustee shall have the right to employ separate counsel in any such suit and
participate in the defence thereof but the fees and expenses of such counsel
shall be at the expense of the Trustee unless: (i) the employment of such
counsel has been authorized by the Parent, Swissco or the Corporation; or (ii)
the named parties to any such suit include both the Trustee and the Parent,
Swissco or the Corporation and the Trustee shall have been advised by counsel
acceptable to the Parent or the Corporation that there may be one or more legal
defenses available to the Trustee which are different from or in addition to
those available to the Parent or the Corporation (in which case the Parent,
Swissco and the Corporation shall not have the right to assume the defence of
such suit on behalf of the Trustee but shall be liable to pay the reasonable
fees and expenses of counsel for the Trustee).

     9.2  LIMITATION OF LIABILITY.  The Trustee shall not be held liable for any
loss which may occur by reason of depreciation of the value of any part of the
Trust Estate or any loss incurred on any investment of funds pursuant to this
trust agreement, except to the extent that such loss is attributable to the
fraud, negligence, wilful misconduct or bad faith on the part of the Trustee.

     10.1 RESIGNATION.  The Trustee, or any trustee hereafter appointed, may at
any time resign by giving written notice of such resignation to the Parent,
Swissco and the Corporation specifying the date on which it desires to resign,
provided that such notice shall never be given less than 30 days before such
desired resignation date unless the Parent, Swissco and the Corporation
otherwise agree and provided further that such resignation shall not take effect
until the date of the appointment of a successor trustee and the acceptance of
such appointment by the successor trustee. Upon receiving such notice of
resignation, the Parent, Swissco and the Corporation shall promptly appoint a
successor trustee by written instrument in duplicate, one copy of which shall be
delivered to the resigning trustee and one copy to the successor trustee.

     10.2 REMOVAL.  The Trustee, or any trustee hereafter appointed, may be
removed at any time on 30 days' prior notice by written instrument executed by
the Parent, Swissco and the Corporation, in duplicate, one copy of which shall
be delivered to the trustee so removed and one copy to the successor trustee.

     10.3  SUCCESSOR TRUSTEE.  Any successor trustee appointed as provided under
this trust agreement shall execute, acknowledge and deliver to the Parent,
Swissco and the Corporation and to its predecessor trustee an instrument
accepting such appointment. Thereupon the resignation or removal of the
predecessor trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become vested with all the rights,
powers, duties and obligations of its predecessor under this trust agreement,
with like effect

                                      D-19

<PAGE>

as if originally named as trustee in this trust agreement. However, on the
written request of the Parent, Swissco and the Corporation or of the successor
trustee, the trustee ceasing to act shall, upon payment of any amounts then due
it pursuant to the provisions of this trust agreement, execute and deliver an
instrument transferring to such successor trustee all the rights and powers of
the trustee so ceasing to act. Upon the request of any such successor trustee,
the Parent, Swissco, the Corporation and such predecessor trustee shall execute
any and all instruments in writing for more fully and certainly vesting in and
confirming to such successor trustee all such rights and powers.


     10.4  NOTICE OF SUCCESSOR TRUSTEE.  Upon acceptance of appointment by a
successor trustee as provided herein, the Parent, Swissco and the Corporation
shall cause to be mailed notice of the succession of such trustee hereunder to
each Beneficiary specified in a List. If the Parent, Swissco or the Corporation
shall fail to cause such notice to be mailed within 10 days after acceptance of
appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Parent, Swissco and the Corporation.

     11.1 CERTAIN REQUIREMENTS IN RESPECT OF COMBINATION, ETC.  The Parent shall
not enter into any transaction (whether by way of reconstruction,
reorganization, consolidation, merger, transfer, sale, lease or otherwise)
whereby all or substantially all of its undertaking, property and assets would
become the property of any other person or, in the case of a merger, of the
continuing corporation resulting therefrom unless, but may do so if:

          (a) such other person or continuing corporation is a corporation
     (herein called the "Parent Successor") incorporated under the laws of any
     state of the United States or the laws of Canada or any province thereof;

          (b) the Parent Successor, by operation of law, becomes, without more,
     bound by the terms and provisions of this trust agreement or, if not so
     bound, executes, prior to or contemporaneously with the consummation of
     such transaction a trust agreement supplemental hereto and such other
     instruments (if any) as are satisfactory to the Trustee and in the opinion
     of legal counsel to the Trustee are necessary or advisable to evidence the
     assumption by the Parent Successor of liability for all moneys payable and
     property deliverable hereunder and the covenant of such Parent Successor to
     pay and deliver or cause to be delivered the same and its agreement to
     observe and perform all the covenants and obligations of the Parent under
     this trust agreement; and

          (c) such transaction shall, to the satisfaction of the Trustee and in
     the opinion of legal counsel to the Trustee, be upon such terms as
     substantially to preserve and not to impair in any material respect any of
     the rights, duties, powers and authorities of the Trustee or of the
     Beneficiaries hereunder

     11.2 VESTING OF POWERS IN SUCCESSOR.  Whenever the conditions of section
11.1 hereof have been duly observed and performed, the Trustee, if required, by
section 11.1 hereof, the Parent Successor and the Corporation shall execute and
deliver the supplemental trust agreement provided for in Article 12 and
thereupon the Parent Successor shall possess and from time to time may exercise
each and every right and power of the Parent under this trust agreement in the
name of the Parent or otherwise and any act or proceeding by any provision of
this trust agreement required to be done or performed by the Board of Directors
of the Parent or any officers of the Parent may be done and performed with like
force and effect by the directors or officers of such Parent Successor

     11.3.  WHOLLY-OWNED SUBSIDIARIES.  Nothing herein shall be construed as

the Parent provided that all of the assets of such subsidiary are transferred to
the Parent or another wholly-owned subsidiary of the Parent and any such
transactions are expressly permitted by this Article 11.

     the provisions of which apply to the Parent, Swissco, the Corporation, the
     Trustee or this trust agreement; and

                   SILICON GRAPHICS AND 3D SOFTWARE INNOVATORS
               ALIAS RESEARCH AND WAVEFRONT TECHNOLOGIES ANNOUNCE
                                MERGER AGREEMENTS

    COMBINED COMPANY TO PROVIDE KEY TOOLS TO EMERGING DIGITAL MEDIA INDUSTRY

NEW YORK, NY (Feb. 7, 1995) -- Silicon Graphics, Inc. (NYSE: SGI), Alias
Research, Inc. (NASDAQ: ADDDF), and Wavefront Technologies, Inc. (NASDAQ: WAVE)
today announced that they have entered into definitive merger agreements.  The
combined organizations bolster Silicon Graphics' commitment to the entertainment
and creative design markets, and allow the company to architect the foundation
necessary for software partners and customers to build the digital studio of the
21st Century.

As a result of the mergers, Silicon Graphics will form a wholly owned,
independent software subsidiary that will focus on developing the world's most
advanced tools for the creation of digital content.  Rob Burgess, currently
president and CEO of Alias, will become president of the new company, and Mike
Noling, currently president and CEO of Wavefront, will report to Burgess as vice
president of operations.  Martin Plaehn, currently Wavefront's executive vice
president of corporate and product development, will also report to Burgess to
lead the technical team.

Under terms of the agreements, which were approved by the boards of directors of
the respective companies, Alias stockholders will receive the equivalent of 0.90
shares of Silicon Graphics' common stock for each share of Alias common stock
owned.  Wavefront stockholders will receive 0.49 shares of Silicon Graphics'
common stock for each share of Wavefront common stock owned.  The closing prices
for Silicon Graphics, Alias and Wavefront common stock on Friday, February 3,
1995, the last trading day prior to the board meetings to approve the
transaction, were $31.25, $20.875 and $12.625, respectively.  The shares to be
issued by Silicon Graphics have a current market value of approximately $500
million.

The merger will be accounted for on a pooling of interest basis and is expected
to be non-dilutive to Silicon Graphics' fiscal year 1996 earnings.  The
transaction is expected to be tax-free for U.S. purposes for Wavefront
shareholders.  In the case of Alias, which is an Ontario, Canada

corporation, the share exchange will be tax-free for Canadian resident
shareholders but taxable for U.S. shareholders.  The combined entities will
receive approximately 9 percent of Silicon Graphics' resulting outstanding
common stock.  The merger is expected to close by June 30, 1995.

"With the creation of this new subsidiary, Silicon Graphics extends its reach in
defining the standard for visual realism and interactivity in the world's most
demanding computing environments: entertainment and industrial design," said
Edward R. McCracken, chairman and CEO of Silicon Graphics.  "Leading-edge
products from Alias and Wavefront are unique and immensely valuable.  Embracing
these assets will enable us to design the power tools that artists and
innovators need to create the digital studio of the 21st Century."

"The applications that will result from this merger will revolutionize the way
our customers will work," said Rob Burgess, president and CEO of Alias.
"Entertainment and creative design users will see amazing things happen to the
software they're using today, and even greater capabilities emerge from our
engineering labs tomorrow."

"Over a decade ago, Wavefront Technologies and Silicon Graphics literally lit
the fuse of the digital explosion in entertainment, and this merger is a natural
next step," said Mike Noling, president and CEO of Wavefront.  "By merging our
talents and resources, collectively we will create products and solutions that
articulate a powerful, exciting future for customers."

The new subsidiary will continue to develop, market, sell and support existing
product lines to a wide range of creative professionals, including 3D animators
for film and video, game and multimedia developers, automotive stylists,
industrial designers and graphic artists.  Silicon Graphics' enhanced ability to
provide sales, support and training services to customers will fuel growth in
these markets.

This new subsidiary will team with Silicon Studio, a subsidiary Silicon Graphics
formed last year to focus on the entertainment market, to develop the world's
most advanced system-level tools for creating digital content.  This
collaboration is expected to result in an open architecture that will

provide significant benefits to customers who use multiple applications.  The
two organizations will also work together to accelerate development and delivery
of FireWalker, a set of tools from Silicon Studio that will allow filmmakers and
other entertainment authors to take original digital source materials and use
them to create interactive titles.  Through a dramatically new approach called
Multimastering, these source materials can not only be used for the initial
project--such as a film or game title--but can be redeployed to other
interactive media, including CD-ROM, location-based entertainment and
interactive television programming.

The mergers follow Silicon Graphics' announcement last month that a total of 22
software companies and production studios have joined its Keystone-TM- software
initiative.  Pioneered by Silicon Graphics, with Alias and Wavefront as charter
members, this new initiative provides the entertainment community with common
application standards that greatly streamline the creative and production
process with minimal data administration.

Completion of the transactions are subject to customary conditions, including
approval of Alias' and Wavefront's stockholders, and required governmental
approvals.
