ITEM 2.   ACQUISITION OR DISPOSITION OF ASSETS.

          In January 1995, Viewlogic Systems, Inc. (the
"Company") purchased a 20% equity interest in Eagle Design
Automation, Inc. ("Eagle") for $500,000.  Gordon Hoffman, a
director of the Company, was the President, a director and a
principal shareholder of Eagle.  In connection with that
purchase, the Company entered into an agreement with Eagle
whereby the Company licensed certain products from Eagle and
Eagle had the right to require the Company to make advance
royalty payments of up to $2,000,000.  In December 1994,
Transitions Three, Limited Partnership ("Transitions Three")
purchased a 20% equity interest in Eagle for $500,000.  Stanley
Alfeld, a director of the Company, is the President and Chief
Executive Officer of TTI Partners, the General Partner of
Transitions Three.  Also, the Company and Transitions Three
guaranteed up to $1,000,000 of debt of Eagle.  On February 19,
1997 the Company exercised its option to purchase all of the
capital stock of Eagle not previously owned by the Company (the
"Purchase").

          The Company paid a total of $5,788,000 in cash to the
shareholders of Eagle for the 80% of Eagle capital stock not
previously owned by the Company, and the Company assumed
liabilities of $100,000 of Eagle and committed to future payments
over the next year to the former shareholders of Eagle of up to
$200,000 based on the shipment of Eagle's backlog.  Also,
$1,475,000 of royalties advanced by the Company to Eagle were
forgiven on completion of the Purchase.  Of the total cash
purchase price, $1,393,000 was paid to Mr. Hoffman and $1,878,000
was paid to Transitions Three.  The Company used available cash
generated from operations to fund the Purchase.  The Company is
also required to pay the prior shareholders of Eagle additional
payments based on the sale by the Company of Eagle's products
over the three year period beginning after certain sales targets
have been met.  Such payments will be distributed amongst the
prior shareholders of Eagle based on their prior share ownership.
No payments are required after that three year period.  There are
no minimum or maximum payments based on the sale of Eagle's
products; however, if current sales projections are met, such
additional payments could total approximately $5,500,000.

          The purchase price was determined in an "arms-length"
negotiation and the Purchase was unanimously approved by the
Boards of Directors of the Company and Eagle.

          Eagle develops and markets hardware/software co-
verification solutions for the embeded systems market. The
Company acquired such products and technology from Eagle through
the Purchase, as well as certain office equipment and furniture.
The Company currently intends to continue Eagle's business
substantially in the manner conducted by Eagle immediately prior
to the Purchase.

                         (REV. 12/4/96)
                                

     This agreement (this "Agreement") is made as of December 17,
1996 by and among Viewlogic Systems, Inc. ("Viewlogic"), Eagle
Design Automation, Inc. ("Eagle"), Transitions Three, Limited
Partnership ("Transitions Three"), Gordon B. Hoffman ("Hoffman"),
Geoffrey J. Bunza ("Bunza"), Linda Bunza, Steven Sapiro and John
Wilson (Hoffman, Bunza, Linda Bunza, Steven Sapiro, John Wilson
and all future shareholders of Eagle who become bound by this
Agreement under section 10 below are referred to herein
collectively as "Shareholders" and individually as a
"Shareholder").

     In consideration of their respective rights and obligations
set forth below, Viewlogic, Eagle, Transitions Three and each of
the Shareholders hereby agree as follow.

     PREAMBLE: Viewlogic, Eagle and Transitions Three are parties
to an agreement made as of December 6, 1994 and entitled
"Investment Agreement" pursuant to which (among other things)
Viewlogic and Transitions Three purchased shares of Eagle's
Series A Preferred Stock, which agreement is referred to herein
as the "Investment Agreement".  Viewlogic and Eagle are parties
to an agreement made as of December 6, 1994 and entitled
"Technology Development Agreement" pursuant to which (among other
things) Viewlogic and Eagle licensed certain technology and
products to each other, which agreement is referred to herein as
the "Development Agreement".  Viewlogic and Eagle are parties to
an agreement made as of December 6, 1994 and entitled "OEM
Agreement" pursuant to which (among other things) Eagle granted
to Viewlogic the right to market and distribute certain products,
which agreement is referred to herein as the "OEM Agreement".
Viewlogic, Eagle, Transitions Three and certain of the
Shareholders are parties to an agreement made as of December 6,
1994 and entitled "Shareholders' Agreement", which was entered
into in connection with the other agreements described above and
which agreement is referred to herein as the "Shareholders
Agreement".  The Investment Agreement, the Development Agreement,
the OEM Agreement and the Shareholders Agreement are collectively
referred to herein as the "Prior Agreements".  Viewlogic, Eagle,
Transitions Three and the Shareholders desire to modify and amend
the Prior Agreements as set forth in this Agreement.  Each of the
Prior Agreements are hereby deemed amended and modified as of the
date first written above to the extent, but only to the extent,
necessary to give effect to this Agreement.  The Prior Agreements
shall remain in full force and effect (according to their
respective terms) as modified by this Agreement.  The Prior
Agreements and this Agreement shall be read consistently and
complementary to the greatest extent possible; however, in the
event of a conflict between any provision of this Agreement and
any provision of any of the Prior Agreements, the provision of
this Agreement shall govern.  Terms defined in any of the Prior
Agreements shall have the meaning assigned to them in that Prior
Agreement when used in this Agreement, unless otherwise indicated
in this Agreement.

     1. PURCHASE: Viewlogic's option, under section 6 of the
Shareholders Agreement, to purchase the capital stock of Eagle is
modified such that (a) Viewlogic shall have the option,
exercisable at any time, to purchase from the other shareholders
of Eagle all of the capital stock of Eagle not already owned by
Viewlogic, and (b) Viewlogic must purchase from the other
shareholders of Eagle all of the capital stock of Eagle not
already owned by Viewlogic within ninety (90) days after
Viewlogic receives written notice from Eagle accompanied by a
written certification from an independent accountant that Eagle
has achieved Consolidated Bookings (as defined below) for
hardware/software codesign products of at least $3,000,000 in any
consecutive twelve month period ending on or before December 31,
1999.  Such purchase, if and when it occurs, shall be based on a
total Option Valuation of Eagle of nine million dollars
($9,000,000) and that amount will not be adjusted (as is the case
with the Purchase Price as set forth in sections 6.2(b)(4) and
6.2(c) of the Shareholders Agreement) as a result of loan
guaranties or
                              5
                        
<PAGE>

prepaid royalties.  Such purchase, if and when it
occurs, shall be implemented as set forth in the Prior Agreements
and shall be a "Deemed Liquidation" as that term is defined in
Article II section D. 2. c of the Restated Articles of
Incorporation of Eagle.  The "Liquidation Price", as that term is
defined in Article II section D. 2. a of the Restated Articles of
Incorporation of Eagle, shall be paid by Viewlogic and the Option
Valuation shall be reduced by the amount of such payment.  In
implementing this purchase of Eagle capital stock by Viewlogic,
all shares of Eagle capital stock held by Hoffman and Bunza will
be treated as fully vested, and all unvested ownership of, and
rights to purchase, Eagle capital stock held by others will be
canceled.  Prior to Viewlogic's purchase of all of the capital
stock of Eagle, Eagle may, subject to consultation with
Viewlogic, accelerate the vesting, according to a fair and
reasonable formula, of the unvested ownership of, and rights to
purchase, Eagle capital stock but such accelerated vesting shall
not increase the total Option Valuation of Eagle which is the
basis of Viewlogic's purchase.  After the purchase of all of the
capital stock of Eagle by Viewlogic, Viewlogic will grant options
to purchase a total of 50,000 shares of Viewlogic common stock to
the former Eagle employees who become Viewlogic employees.  Such
stock option grants will be consistent with Viewlogic's policies
and practices applicable to its employees generally, will have a
stock purchase price at the fair market value of such stock on
the date of grant and will be subject to approval by Viewlogic's
board of directors.  Viewlogic and Eagle will jointly determine
the allocation of such stock options among the eligible
individuals.  Viewlogic shall have no obligation to purchase any
capital stock of Eagle if Eagle has not achieved three million
dollars ($3,000,000) of Consolidated Bookings for
hardware/software codesign products in any consecutive twelve-
month period ending on or before the close of business on
December 31, 1999.  Viewlogic's purchase of Eagle capital stock
shall be subject to: (a) Viewlogic completing the customary "due
diligence" investigation of Eagle with results satisfactory to
Viewlogic; (b) Viewlogic's receipt from Eagle of the same
representations and warranties provided by Eagle in the Prior
Agreements updated as of the time of purchase and with exceptions
and an updated Disclosure Schedule reasonably satisfactory to
Viewlogic and Viewlogic's receipt from each Shareholder of the
same representations and warranties provided by the shareholders
of Eagle in the Prior Agreements updated as of the time of
purchase and with exceptions and an updated Disclosure Schedule
reasonably satisfactory to Viewlogic; (c) the customary
conditions to purchases of this nature; and (d) all other terms,
conditions and provisions in the Prior Agreements.

     Consolidated Bookings means the total net value (after
discounts and credits for returns and excluding all taxes,
insurance, duties, shipping and all similar charges) of all valid
orders for hardware/software codesign products, including orders
for consulting services and support, accepted by Eagle during the
relevant time period from all sources, except Viewlogic, where
orders are received directly by Eagle; plus the total net amount
(after credits for returns, exchanges and all similar matters) of
all royalties actually payable to Eagle for the relevant time
period from all sources, except Viewlogic, based on the sale of
hardware/software codesign products, including royalties for
consulting services and support; plus the total net value (after
discounts and credits for returns and excluding all taxes,
insurance, duties, shipping and all similar charges) of all valid
orders accepted by Viewlogic during the relevant time period for
hardware/software codesign products on which Viewlogic is
obligated to pay any royalties to Eagle.  Orders and/or royalty
payments for one year that are debooked or adjusted in another
year shall reduce the Consolidated Bookings for the year in which
the debooking or adjustment occurred, except that orders and/or
royalty payments in the Third Earnout Year (as defined below)
which are debooked or adjusted after the Third Earnout Year shall
reduce the Consolidated Bookings for the Third Earnout Year and
the Earnout Payment (as defined below) for the Third Earnout Year
shall be appropriately adjusted and all recipients of an Earnout
Payment for the Third Earnout Year shall promptly refund any
overpayment to Viewlogic.

     2. EARNOUT: If Viewlogic purchases all of the capital stock
of Eagle as set forth in section 1 above, Viewlogic will pay to
the former shareholders of Eagle (including Viewlogic), in the
same proportion as their share ownership of Eagle which was the
basis for the payments made under section 1 above, payments (the
"Earnout Payments") based on the Consolidated Bookings of
hardware/software codesign products sold by Viewlogic.  Viewlogic
will calculate the Consolidated Bookings for hardware/software
codesign products sold by Viewlogic in each of the three
consecutive twelve-month periods following the twelve-month
period in which Eagle (or its successor) first achieved three
million dollars ($3,000,000) of Consolidated Bookings (the "First
Earnout Year", "Second Earnout Year" and "Third Earnout Year",
respectively).  If Consolidated Bookings for hardware/software

                               6
<PAGE>

codesign products are at least five million dollars ($5,000,000)
in the First Earnout Year, eight and one-half million dollars
($8,500,000) in the second Earnout Year and ten million dollars
($10,000,000) in the third Earnout Year, then the Earnout
Payments to be made by Viewlogic for the applicable Earnout Year
shall be as follows:

     First Earnout Year: sixty cents ($.60) for each dollar of
Consolidated Bookings for hardware/software codesign products
over five million dollars ($5,000,000).

     Second Earnout Year: fifty cents ($.50) for each dollar of
Consolidated Bookings for hardware/software codesign products
over eight and one-half million dollars ($8,500,000) and below
ten and one-half million dollars ($10,500,000); thirty-three
cents ($.33) for each dollar of Consolidated Bookings for
hardware/software codesign products over ten and one-half million
dollars ($10,500,000) and below thirteen and one-half million
dollars ($13,500,000); and twenty-eight and six tenths cents
($.286) for each dollar of Consolidated Bookings for
hardware/software codesign products over thirteen and one-half
million dollars ($13,500,000).

     Third Earnout Year: sixty cents ($.60) for each dollar of
Consolidated Bookings for hardware/software codesign products
over ten million dollars ($10,000,000) and below twelve million
dollars ($12,000,000); forty cents ($.40) for each dollar of
Consolidated Bookings for hardware/software codesign products
over twelve million dollars ($12,000,000) and below fifteen
million dollars ($15,000,000); and ten cents ($.10) for each
dollar of Consolidated Bookings for hardware/software codesign
products over fifteen million dollars ($15,000,000).

     No Earnout Payment will be paid for any Earnout Year in
which Consolidated Bookings for Viewlogic's sale of
hardware/software codesign products do not exceed the minimum
amounts set forth above.  No Earnout Payment, and no other
compensation, will be paid for the sale or booking of
hardware/software codesign products after the Third Earnout Year.
Viewlogic shall have no obligation to make any payments with
respect to the purchase of the capital stock of Eagle beyond that
expressly set forth in sections 1 and 2 hereof.

     3. FUNDING: Viewlogic shall have no obligation to make
payments of prepaid royalties to Eagle.  The unearned portion of
the first one million four hundred and seventy-five thousand
dollars ($1,475,000) of prepaid royalties previously paid to
Eagle by Viewlogic will not be credited against future royalties
due by Viewlogic to Eagle according to paragraph 6.1 of the OEM
Agreement, and Viewlogic will pay future royalties to Eagle
pursuant to the OEM Agreement without regard to such prepaid
royalties.  If Viewlogic purchases all of the capital stock of
Eagle as set forth in section 1 above, Eagle shall have no
obligation to repay the unearned portion of the first one million
four hundred and seventy-five thousand dollars ($1,475,000) of
prepaid royalties.  If Viewlogic does not purchase all of the
capital stock of Eagle, the unearned portion of the first one
million four hundred and seventy-five thousand dollars
($1,475,000) of prepaid royalties shall be converted to a loan
from Viewlogic to Eagle as if made on January 1, 2000, Eagle
shall sign a promissory note in the form attached hereto as
Exhibit A (with appropriate changes to reflect the particular
loan), and that loan shall be repaid as described below in this
section 3.

     Neither Viewlogic nor Transitions Three shall have any
obligation to guaranty any debt of, or loans to, Eagle in excess
of the one hundred thousand dollars ($100,000) currently
guaranteed by Viewlogic and Transitions Three.  Eagle shall not
allow the amount outstanding under its credit line with Silicon
Valley Bank to exceed the one hundred thousand dollars ($100,000)
currently outstanding thereunder.  Eagle shall not incur any debt
in excess of Eagle's debt existing on the date of this Agreement,
except for the loans to Eagle by Viewlogic contemplated by this
Agreement.  If Viewlogic purchases Eagle, Viewlogic will repay
the amount outstanding under Eagle's credit line with Silicon
Valley Bank up to a maximum of one hundred thousand dollars
($100,000).

     Prior to Viewlogic's acquisition of Eagle or December 31,
1999, whichever first occurs, Viewlogic will make loans to Eagle
to be used only as working capital, if, as and when requested by
Eagle in writing and upon Eagle signing a promissory note in the
form attached hereto as Exhibit A (with appropriate changes to
reflect each particular loan).  Such loans shall not exceed one
million two hundred thousand dollars ($1,200,000).  Eagle
acknowledges that nine hundred and fifty thousand dollars
($950,000) of such maximum loan amount has

                                 7
<PAGE>

previously been loaned to Eagle and 
Eagle has executed a promissory note as required
above, a copy of which is attached hereto as Exhibit B. 
If Eagle and Viewlogic both agree in writing, Viewlogic may make
additional loans to Eagle and Eagle will sign a promissory note
in the form attached hereto as Exhibit A (with appropriate
changes to reflect the particular loan).  If Eagle requests
aggregate loans in excess of one million two hundred thousand
dollars ($1,200,000) and less than three million one hundred
thousand dollars ($3,100,000) and Viewlogic does not wish to make
such excess loans to Eagle, Viewlogic will so notify Eagle in
writing and in a timely manner, and Viewlogic will thereafter no
longer have the option to purchase any Eagle capital stock, the
obligation to purchase any Eagle capital stock nor the right of
first refusal to purchase any Eagle capital stock, and Eagle may
then proceed to obtain funding from sources other than Viewlogic.
There shall be no effect on Viewlogic's option to purchase Eagle
capital stock, Viewlogic's obligation to purchase Eagle capital
stock nor Viewlogic's right of first refusal to purchase Eagle
capital stock for Viewlogic's failure to make aggregate loans to
Eagle in excess of three million one hundred thousand dollars
($3,100,000).  Eagle shall have the right to repay any and all
loans made by Viewlogic at any time and from time to time without
penalty.  If all loans have not been repaid by Eagle prior to
Viewlogic's purchase of all capital stock of Eagle and if
Viewlogic purchases all capital stock of Eagle as set forth in
section 1 above, then (a) the Purchase Price which is payable to
the shareholders of Eagle, other than Viewlogic, shall be reduced
dollar for dollar by the amount required to repay all loans in
full and (b) Viewlogic shall place in escrow a portion of the
amount required to repay such loans (but not more than the full
amount required to repay such loans) equal to the amount of money
equal to the net amount of Eagle's unshippable orders for
hardware/software codesign products which are scheduled to be
shipped within the next twelve months and Viewlogic shall pay to
the appropriate former shareholders of Eagle, except Viewlogic,
an amount equal to such unshippable orders for hardware/software
codesign products which are in fact shipped in that twelve month
period but not more than the full amount placed in escrow.

     In any event, if Viewlogic does not purchase all capital
stock of Eagle, all loans which have not been repaid in full
prior to December 31, 1999, and all other sums which are
converted to loans as set forth herein, will be repaid by Eagle
in four equal consecutive quarterly installments of principal and
interest with the first payment due on April 1, 2000.  All such
loans will bear interest at the prime rate in effect on the date
the loan is made, interest will accrue from the date the loans
were first made, no interest payments will be required until the
first payment of principal is due at which time all interest due
through that date will be paid.  Viewlogic shall have the right,
at any time and from time to time, to offset any and all moneys
owed by Viewlogic to Eagle against any and all moneys owed by
Eagle to Viewlogic.

     4. NEW PROJECTS: At any time and from time to time, Eagle
and Viewlogic may mutually determine that Eagle should develop a
hardware/software codesign product or conduct a project related
to hardware/software codesign products not then contemplated by
Eagle's business plan.  In such case, Eagle will submit a
business plan for approval by Viewlogic which business plan must
include, as projected for the next twelve month period, an income
statement, a balance sheet, a statement of cash flows and a
detailed description of Eagle's business.  If Viewlogic approves
the business plan in its sole discretion and if the business plan
shows an operating loss, Viewlogic will loan to Eagle an amount
of money sufficient to enable Eagle to break even in terms of
operating income according to that business plan and Eagle shall
sign a promissory note in the form attached hereto as Exhibit A
(with appropriate changes to reflect the particular loan).  All
money loaned to Eagle under this provision will be repaid and
treated the same as the loans described in section 3 above.

     5. RIGHT OF FIRST REFUSAL: The Financing Refusal Period (as
defined in section 2.2 of the Investment Agreement), and the
Refusal Period (as defined in section 4.2 of the Shareholders
Agreement) and the Sale Refusal Period (as defined in section 5.2
of the Shareholders Agreement) are each shortened from ninety
(90) days to thirty (30) days.  The time period of ten (10) days
specified in the last sentence of section 2.2 of the Investment
Agreement is increased to thirty (30) days.  Viewlogic's right of
first refusal under section 4 of the Shareholders Agreement shall
be subject to the right of Eagle, if such right exists, to
repurchase from employees of Eagle shares of Eagle capital stock
pursuant to the terms of any stock option agreement between Eagle
and such employee.
                               8

     6. ROYALTIES: Prior to Viewlogic's purchase of all of the
capital stock of Eagle or December 31, 1999, whichever first
occurs, the royalties payable by Viewlogic under the OEM
Agreement for the sale of hardware/software codesign products
will be paid monthly within thirty days after the applicable
month rather than quarterly.  After December 31, 1999, if
Viewlogic has not purchased all of the capital stock of Eagle,
then royalties payable by Viewlogic under the OEM Agreement for
the sale of hardware/software codesign products will again be
paid quarterly, as set forth in the OEM Agreement.

     7. SALES ORGANIZATION: Eagle's Vice President of Sales (or
highest level sales person if there is no Vice President of
Sales) shall devote his or her efforts substantially full time
(meaning an average of 35 hours per week in each 3 month period)
to assist Viewlogic in building, developing and training a
Viewlogic sales force which is fully qualified to sell
hardware/software codesign products.  Eagle's Vice President of
Sales will have the responsibility and authority of a direct
report to Viewlogic's Senior Vice President of Sales.  Prior to
March 31, 1997, Viewlogic will assign quota for hardware/software
codesign products to at least one Application Engineer and one
Sales Representative in each of Viewlogic's Eastern USA, Western
USA and European sales territories.  Viewlogic accepts, as
bonafide sales targets, Eagle's forecast of Eagle's Consolidated
Bookings for hardware/software codesign products as follows: for
calendar year 1997 $5,000,000; for calendar year 1998
$10,000,000; and for calendar year 1999 $17,000,000.  If
Viewlogic purchases all of the capital stock of Eagle, Viewlogic
will, at least until the end of the Third Earnout Year, keep
staffing for hardware/software codesign products at levels
consistent with good business practices and with product
opportunities.

     8. OFFICES: Until June 30, 2000, Viewlogic will maintain an
office in or near Beaverton, Oregon for the marketing and
engineering of hardware/software codesign products.

     9. TRANSITIONS THREE: Transitions Three's right to require
Viewlogic to purchase the shares of Eagle capital stock held by
Transitions Three, as set forth in section 7 of the Shareholders
Agreement, shall remain as is in the Shareholders Agreement and
completely unaffected by this Agreement.

     10. SHAREHOLDERS: By signing this Agreement, each
Shareholder acknowledges and agrees that they are bound by the
Shareholders Agreement, as modified by this Agreement, as fully
as if they had signed the Shareholders Agreement.  Eagle shall
not issue any shares of its capital stock to any person or entity
unless and until such person or entity signs and agrees to be
legally bound by this Agreement.

     Agreed, accepted and executed as a sealed instrument by
Viewlogic, Eagle, Transitions Three and each of the Shareholders.

     Eagle represents and warrants to Viewlogic that the
statements contained in this Article 2 are true and correct,
except as set forth in the disclosure schedule attached hereto
(the "Disclosure Schedule").

2.1       ORGANIZATION AND STANDING.  Eagle is a corporation duly
     organized and validly existing under the laws of the State
     of Oregon and has full corporate power and authority to
     conduct its business as presently conducted and as proposed
     to be conducted by it and to enter into and perform this
     Agreement and to carry out the transactions contemplated by
     this Agreement.  Eagle is duly qualified to do business as a
     foreign corporation and is in good standing in every
     jurisdiction in which the failure to so qualify would have a
     material adverse effect on the operations or financial
     condition of Eagle.  Eagle has furnished to Viewlogic true
     and complete copies of its Articles of Incorporation and By-
     laws, each as altered or amended to date and presently in
     effect.

2.2  CAPITALIZATION.  The authorized capital stock of Eagle
     consists of 10,000,000  shares of Common Stock, $0.01 par
     value per share ("Common Stock"), of which 4,372,500  shares
     are issued and outstanding, and 3,000,000  shares of
     Series A Preferred Stock, of which 2,055,470  are issued and
     outstanding.  There are no shares of capital stock of Eagle
     held in the treasury of Eagle.  All of the issued and
     outstanding shares of capital stock of Eagle have been duly
     authorized and validly issued and are fully paid and
     nonassessable.  Except as set forth in the Disclosure
     Schedule hereto or provided in this Agreement, (i) no
     subscription, warrant, option, convertible security or other
     right (contingent or otherwise) to purchase or acquire any
     shares of capital stock of Eagle is authorized or
     outstanding, (ii) Eagle has no obligation (contingent or

                               16
<PAGE>

     otherwise) to issue any subscription, warrant, option,
     convertible security or other such right or to issue or
     distribute to holders of any shares of its capital stock any
     evidences of indebtedness or assets of Eagle, and
     (iii) Eagle has no obligation (contingent or otherwise) to
     purchase, redeem or otherwise acquire any shares of its
     capital stock or any interest therein or to pay any dividend
     or make any other distribution in respect thereof.  All of
     the issued and outstanding shares of capital stock of Eagle
     have been offered, issued and sold by Eagle in compliance
     with applicable laws.

2.3  TAX MATTERS.  Eagle has filed all Tax Returns (as defined
     below) that it was required to file and all such Tax Returns
     were correct and complete in all material respects.  Eagle
     has paid all Taxes (as defined below) that are shown to be
     due on any such Tax Returns.  The unpaid Taxes of Eagle for
     tax periods through the date of the Most Recent Balance
     Sheet do not exceed the accruals and reserves for Taxes set
     forth on the Most Recent Balance Sheet.  To Eagle's
     knowledge, Eagle has no actual or potential liability for
     any Tax obligation of any taxpayer (including without
     limitation any affiliated group of corporations or other
     entities that included Eagle during a prior period) other
     than Eagle.  For purposes of this Agreement, "Taxes" means
     all taxes, charges, fees, levies or other similar
     assessments or liabilities, including without limitation
     income, gross receipts, ad valorem, premium, value-added,
     excise, real property, personal property, sales, use,
     transfer, withholding, employment, payroll and franchise
     taxes imposed by the United States of America or any state,
     local or foreign government, or any agency thereof, or other
     political subdivision of the United States or any such
     government, and any interest, fines, penalties, assessments
     or additions to tax resulting from, attributable to or
     incurred in connection with any tax or any contest or
     dispute thereof.  For purposes of this Agreement, "Tax
     Returns" means all reports, returns, declarations,
     statements or other information legally required to be
     supplied to a taxing authority in connection with Taxes.
     Eagle has delivered to Viewlogic correct and complete copies
     of all federal income Tax Returns, examination reports and
     statements of deficiencies assessed against or agreed to by
     Eagle since inception.   No examination or audit of any Tax
     Returns of Eagle by any governmental entity has been
     conducted, is currently in progress or, to the knowledge of
     Eagle, threatened or contemplated.

2.4  SUBSIDIARIES, ETC.  Eagle has no subsidiaries and does not
     own or control, directly or indirectly, any shares of
     capital stock of any other corporation or any interest in
     any partnership, joint venture or other non-corporate
     business enterprise.

     Disclosure Schedule is a true and complete list of the
     stockholders of Eagle, showing the number of shares of stock
     of Eagle or other securities of Eagle held by each
     stockholder and the consideration paid to Eagle, if any,
     therefor, as well as the holders of all options and warrants
     to acquire capital stock of Eagle, and the exercise prices
     thereof. Except as provided in this Agreement, there are no
     written, and to the knowledge of any Holder no oral
     agreements between Eagle and any holder of its capital
     stock, or, to Eagle's knowledge there are no oral or written
     agreements among any holders of its capital stock, relating
     to the acquisition (including without limitation rights of

     agreements required to be executed by Eagle in connection
     with the transactions contemplated hereby, and the
     consummation by Eagle of the transactions contemplated
     hereby and thereby, have been duly authorized by all
     necessary corporate action.  This Agreement has been duly
     executed and delivered by Eagle and constitutes the valid
     and binding obligation of Eagle enforceable in accordance
     with its terms except as enforcement may be limited by
     bankruptcy, insolvency, fraudulent conveyance,
     reorganization, moratorium, or other similar laws relating
     to or affecting the enforcement of creditors' rights
     generally.

2.7  NONCONTRAVENTION.  The execution, delivery and performance
     of this Agreement and compliance with the provisions hereof
     by Eagle, do not and will not, with or without the passage
     of time or the giving of notice or both, (A) violate any
     provision of law, statute, rule or regulation, or any
     ruling, writ, injunction, order, judgment or decree of any

     agreement or other instrument or document to which Eagle
     is a party or its Articles of Incorporation or By-laws.

2.8  GOVERNMENTAL CONSENTS.  No consent, approval, order or
     authorization of, or registration, qualification,
     designation, declaration or filing with, any governmental

2.9  LITIGATION.  There is no action, suit or proceeding, or
     governmental inquiry or investigation, pending, or, to the
     best of Eagle's knowledge, any basis therefor, against Eagle
     which questions the validity of this Agreement or the right
     of Eagle to enter into it, or which might result, either
     individually or in the aggregate, in any material adverse
     change in the business, prospects, assets or condition,
     financial or otherwise, of Eagle, nor is there any
     litigation pending, or, to Eagle's knowledge, any basis
     therefor, against Eagle by reason of the proposed activities
     of Eagle.

2.10 FINANCIAL STATEMENTS.  Eagle has provided to Viewlogic
     (a) its unaudited balance sheets and statements of
     operations, changes in stockholders' equity and cash flows
     for each of the last two fiscal years ended December 31,
     1995 and 1996; (b) its unaudited consolidated balance sheet
     and statements of operations, changes in stockholders'
     equity and cash flows as of the year ended December 31, 1996
     (the "Most Recent Fiscal Year End"), and (c) an unaudited
     interim consolidated balance sheet and statements of income,
     changes in stockholders' equity and cash flows for Eagle as
     of and for the most recent month end.  Such financial
     statements (collectively, the "Financial Statements") fairly
     present the financial condition, results of operations and
     cash flows of Eagle as of the respective dates thereof and
     for the periods referred to therein and are consistent with
     the books and records of Eagle.  Eagle has no liability
     (whether known or unknown, whether absolute or contingent,
     whether liquidated or unliquidated and whether due or to
     become due), except for (i) liabilities shown on the
     December 31, 1996 balance sheet referred to in clause (a)
     above (the "Most Recent Balance Sheet"), (ii) liabilities
     which have arisen after the Most Recent Fiscal Year End in
     the ordinary course of business and which are not in the
     aggregate material and (iii) contractual liabilities
     incurred in the ordinary course of business which are not
     required to be reflected on the Most Recent Balance Sheet.
     All accounts receivable of Eagle reflected on the Most
     Recent Balance Sheet are valid receivables subject to no
     setoffs or counterclaims and are current and collectible
     (within 90 days after the date on which it first became due
     and payable), net of the applicable reserve for bad debts
     shown on the Most Recent Balance Sheet.  All accounts
     receivable reflected in the financial or accounting records
     of Eagle that have arisen since the Most Recent Fiscal Year
     End are valid receivables subject to no setoffs or
     counterclaims and are collectible, net of a reserve for bad
     debts in an amount proportionate to the reserve shown on the
     Most Recent Balance Sheet.


2.11 PROPERTY AND ASSETS.  Eagle owns or leases all tangible
     assets necessary for the conduct of its businesses as
     presently conducted and as presently proposed to be
     conducted.  No such tangible asset owned or purported to be
     owned by Eagle is subject to any security interest, and, to
     Eagle's knowledge, no tangible asset leased by Eagle is
     subject to any security interest.  Each such tangible asset
     is free from material defects, has been maintained in
     accordance with normal industry practice, is in good
     operating condition and repair (subject to normal wear and
     tear) and is suitable for the purposes for which it
     presently is used.  Eagle owns no real property.

2.12 INTELLECTUAL PROPERTY.

     (1)  Eagle owns or has the right to use all Intellectual
          Property (as defined below) used in the operation of
          its business or necessary for the operation of its
          business as presently proposed to be conducted.  Each
          item of Intellectual Property owned by or used in the
          operation of the business of Eagle will be owned or
          available for use by Eagle or Viewlogic on identical
          terms and condi-

                                  18
<PAGE>

          tions (other than terms and conditions
          affected by the lapse of time) immediately following
          the date hereof.  Eagle has taken all reasonable
          measures to protect the proprietary nature of each item
          of Intellectual Property owned by it or licensed to it
          on terms requiring that such measures be taken, and to
          maintain in confidence all trade secrets and
          confidential information, that it owns or that it is
          licensed to use on terms requiring that it maintain
          such trade secrets or confidential information in
          confidence.  No other person or entity has any rights
          to any of the Intellectual Property owned or used by
          Eagle (except pursuant to agreements or licenses
          specified in the Disclosure Schedule), and to Eagle's
          knowledge no other person or entity is infringing,
          violating or misappropriating any of the Intellectual
          Property that Eagle currently owns or uses.  For
          purposes of this Agreement, "Intellectual Property"
          means all (i) patents, patent applications, and all
          related continuation, continuation-in-part, divisional,
          reissue, reexamination, utility, model, certificate of
          invention and design patents, patent applications,
          registrations and applications for registrations,
          (ii) trademarks, service marks, trade dress, logos,
          trade names and corporate names and registrations and
          applications for registration thereof, (iii) copyrights
          and registrations and applications for registration
          thereof, (iv) mask works and registrations and
          applications for registration thereof, (v) computer
          software, data and documentation, (vi) trade secrets
          and confidential business information, whether
          patentable or unpatentable and whether or not reduced
          to practice, know-how, manufacturing and production
          processes and techniques, research and development
          information, copyrightable works, financial, marketing
          and business data, pricing and cost information,
          business and marketing plans and customer and supplier
          lists and information, (vii) other proprietary rights
          relating to any of the foregoing and (viii) copies and
          tangible embodiments thereof.

     (2)  None of the activities or business conducted presently
          by Eagle or in the past, infringes or violates, or
          constitutes a misappropriation of, any Intellectual
          Property rights of any other person or entity.  Eagle
          has not received any complaint, claim or notice
          alleging any such infringement, violation or
          misappropriation.

     (3)  Section 2.12(3) of the Disclosure Schedule lists or
          describes all material Intellectual Property of Eagle,
          and identifies each license or other agreement pursuant
          to which Eagle has granted any rights to any third
          party with respect to any of its Intellectual Property.
          Except as set forth in Section 2.12(3) of the
          Disclosure Schedule, with respect to each item of
          Intellectual Property that Eagle owns or purports to
          own:  Eagle possesses all right, title and interest in
          and to such item; such item is not subject to any
          outstanding judgment, order, decree, stipulation or
          injunction; and Eagle has not agreed to indemnify any
          person or entity for or against any infringement,
          misappropriation or other conflict with respect to such
          item.

     (4)  The Disclosure Schedule identifies each item of
          Intellectual Property which is material to the
          operation of the business of Eagle at any time during
          the period covered by the Financial Statements, or that
          Eagle plans to use in the future, that is owned by a
          party other than Eagle.  Eagle has supplied Viewlogic
          with correct and complete copies of all licenses,
          sublicenses or other agreements (as amended to date)
          pursuant to which Eagle uses such Intellectual
          Property, all of which are listed on Section 2.12(4) of
          the Disclosure Schedule.  Except as set forth in
          Section 2.12(4) of the Disclosure Schedule, with
          respect to each such item of Intellectual Property:
          the license, sublicense or other agreement, covering
          such item is legal, valid, binding, enforceable and in
          full force and effect; such license, sublicense or
          other agreement will continue to be legal, valid,
          binding, enforceable and in full force and effect
          immediately following the Closing in accordance with
          the terms thereof as in effect prior to the Closing; to
          Eagle's knowledge, no party to such license, sublicense
          or other agreement is in material breach or default,
          and no event has occurred which with notice or lapse of
          time would constitute a material breach or default or
          permit termination, modification or acceleration
          thereunder; to Eagle's knowledge, the underlying item
          of Intellectual Property is not subject to any
          outstanding judgment, order, decree, stipulation or
          injunction; and Eagle has never agreed to indemnify any

                                   19
<PAGE>

          person or entity for or against any interference,
          infringement, misappropriation or other conflict with
          respect to such item.

2.13 INSURANCE.  Eagle maintains valid policies of workers'
     compensation insurance and insurance with respect to its
     properties and business and directors and officers of the
     kinds and in the amounts not less than is customarily
     obtained by corporations of established reputation engaged
     in the same or similar business and similarly situated,
     including, without limitation, insurance against loss,
     damage, fire, theft, public liability and other risks.

2.14 MATERIAL CONTRACTS AND OBLIGATIONS.  The Disclosure Schedule
     sets forth a list of all written material agreements or
     commitments, and to Eagle's knowledge all material oral
     agreements or commitments, of any nature to which Eagle is a
     party or by which it is bound.  Eagle has delivered to
     Viewlogic copies of the foregoing written agreements.  All
     of such oral and written agreements and contracts are valid,
     binding and in full force and effect.

2.15 COMPLIANCE.  Eagle has, in all material respects, complied
     with all laws, regulations and orders applicable to its
     present and proposed business and has all material permits
     and licenses required thereby.  There is no term or provi
     sion of any mortgage, indenture, contract, agreement or
     instrument to which Eagle is a party or by which it is
     bound, or, to the best of Eagle's knowledge, any provision
     of any judgment, decree, order, statute, rule or regulation
     applicable to or binding upon Eagle, which materially
     adversely affects or, so far as Eagle may now foresee, in
     the future is reasonably likely to materially adversely
     affect, the business, prospects, assets or condition,
     financial or otherwise, of Eagle.  To the best of Eagle's
     knowledge, no employee of Eagle is in violation of any term
     of any contract or covenant (either with Eagle or with
     another entity) relating to employment, intellectual
     property, proprietary information disclosure, non-
     competition or non-solicitation.

2.16 EMPLOYEES.  All employees of Eagle whose employment
     responsibility requires access to confidential or
     proprietary information of Eagle have executed and delivered
     nondisclosure and assignment of invention agreements in a
     form which has been provided to Viewlogic, and all of such
     agreements are in full force and effect.

     are set forth and described on the Disclosure Schedule.

2.18 BOOKS AND RECORDS.  The minute books of Eagle contain
     complete and accurate records of all meetings and other
     corporate actions of its stockholders and its Board of
     Directors and committees thereof.  The stock ledger of Eagle
     is complete and reflects all issuances, transfers,
     repurchases and cancellations of shares of capital stock of
     Eagle.

2.19 ABSENCE OF CHANGES.  Since the Most Recent Fiscal Year End,
     there has been no material adverse change in the condition,
     financial or otherwise, net worth or results of operations
     of Eagle, other than changes occurring in the ordinary
     course of business which changes have not, individually or
     in the aggregate, had a materially adverse effect on the
     business, prospects, properties or condition, financial or
     otherwise, of Eagle.

2.20 DISCLOSURES.  Neither this Agreement nor any Exhibit hereto,
     nor any report, certificate or instrument furnished to
     Viewlogic in connection with the transactions contemplated
     by this Agreement, when read together, contains or will
     contain any untrue statement of a material fact or omits or
     will omit to state a material fact necessary in order to
     make the statements contained herein or therein, in light of
     the circumstances under which they were made, not
     misleading.  Eagle knows of no information or fact which has
     or would have a material adverse effect on the business,
     prospects, assets or condition, financial or otherwise, of
     Eagle which has not been disclosed in the Disclosure
     Schedule.

                        INDEMNIFICATION

5.1  INDEMNIFICATION.

     (1)  Subject to the terms and conditions of this Article 5
          and the limitation set forth in Section 5.8 below, the
          Holders (the "Indemnifying Persons") shall indemnify
          Viewlogic and its Affiliates, officers, directors,
          shareholders and subsidiaries (including Eagle
          following the Closing) (the "Indemnified Persons") in
          respect of, and hold the Indemnified Persons harmless
          against, any and all debts, obligations and other
          liabilities (whether absolute, accrued, fixed or
          otherwise, or whether known or unknown, or due or to
          become due or otherwise), monetary damages, fines,
          fees, penalties, interest obligations, deficiencies,
          losses and expenses (including without limitation
          amounts paid in settlement, interest, court costs,
          costs of investigators, fees and expenses of attorneys,
          accountants, financial advisors and other experts, and
          other expenses of litigation) actually incurred or
          suffered by the Indemnified Persons ("Damages")
          resulting from or constituting any misstatement or
          omission of Eagle in Article 2 of this Agreement or any
          breach of any warranty in Article 2 of this Agreement
          (as qualified by the Disclosure Schedule).

     (2)  Subject to the terms and conditions of this Article 5
          and the limitation set forth in Section 5.8 below, each
          Indemnifying Person hereby agrees to indemnify the
          Indemnified Persons in respect of, and hold the
          Indemnified Persons harmless against any and all
          Damages resulting from  any failure of such
          Indemnifying Person to have good, valid and marketable
          title to the issued and outstanding Eagle Securities
          held by such Indemnifying Person, free and clear of all
          liens, claims, pledges, options, adverse claims or
          charges of any nature whatsoever; or  any claim by a
          security holder or former security holder of Eagle, or
          any other person, firm, corporation or entity, seeking
          to assert, or based upon ownership or rights associated
          with ownership of any Eagle securities owned or claimed
          to be owned by such Indemnifying Person; or any
          misstatement or omission of such Holder in Article 3 of
          this Agreement or any breach of any warranty in Article
          3 of this Agreement.

5.2  CLAIM NOTICE.  If an Indemnified Person has incurred or
     suffered Damages for which it is or may be entitled to
     indemnification hereunder, such Indemnified Person shall,
     during the Indemnity Period, give written notice of such
     claim (a "Claim Notice") to the Indemnification
     Representative (as defined below).  Each Claim Notice shall
     state the amount of claimed Damages, to the extent then
     known, (the "Claimed Amount") and the basis for such claim.
     Within 20 days after delivery of the Claim Notice, the
     Indemnification Representative may, upon written notice
     thereof to the Indemnified Person, assume control of the
     defense of such action, suit or proceeding with counsel
     reasonably satisfactory to the Indemnified Person, provided
     the Indemnification Representative acknowledges in writing
     to the Indemnified Person that any damages, fines, costs or
     other liabilities that may be assessed against the
     Indemnified Person in connection with such action, suit or
     proceeding constitute Damages for which the Indemnified
     Person shall be entitled to indemnification pursuant to this
     Article 5.  If the Indemnification Representative does not
     so assume control of such defense, the Indemnified Person
     shall control such defense.  The party not controlling such
     defense may participate therein at its own expense; provided
     that if the Indemnification Representative assumes control
     of such defense and the Indemnified Person reasonably
     concludes that the Indemnifying Persons and the Indemnified
     Person have conflicting interests or different defenses
     available with respect to such action, suit or proceeding,
     the reasonable fees and expenses of counsel to the
     Indemnified Person shall be considered "Damages" for
     purposes of this Agreement to the extent such fees and
     expenses are incurred to defend a claim for which an
     Indemnified Person is entitled to indemnity hereunder.  The
     party controlling such defense shall keep the other party
     advised of the status of such action, suit or proceeding and
     the defense thereof and shall consider in good faith
     recommendations made by the other party with respect
     thereto.  The party controlling such defense shall not agree
     to any settlement

                                22
<PAGE>

     of such action, suit or proceeding without the prior written
     consent of the other party, which shall not be unreasonably withheld.

5.3  RESPONSE NOTICE.  Within 10 days after delivery of a Claim
     Notice, the Indemnification Representative shall provide to
     the Indemnified Persons a written response (the "Response
     Notice") in which the Indemnification Representative shall
     either agree or disagree with the assertion of damages in
     the Claim Notice.  If no Response Notice is delivered by the
     Indemnification Representative within such 10-day period,
     the Indemnification Representative shall be deemed to have
     agreed that the Claimed Amount constitutes Damages.

5.4  CONTESTED CLAIMS.   If the Indemnification Representative in
     the Response Notice contests all or any part of the Claimed
     Amount (the "Contested Amount"), the matter shall be settled
     by binding arbitration in Boston,  Massachusetts.  All
     claims shall be settled by three arbitrators in accordance
     with the Commercial Arbitration Rules then in effect of the
     American Arbitration Association (the "AAA Rules").  The
     Indemnification Representative shall have the right to
     employ his own legal counsel to represent such person in any
     disputes arising under this Agreement.  The Indemnification
     Representative and the Indemnified Persons shall each
     designate one arbitrator within 15 days of the delivery of
     the Indemnification Representative's Response Notice
     contesting the Claimed Amount.  Such designated arbitrators
     shall mutually agree upon and shall designate a third
     arbitrator; provided, however, that (i) failing such
     agreement within fifteen (15) days of delivery of the
     Indemnification Representative's Response Notice, the third
     arbitrator shall be appointed in accordance with the AAA
     Rules and (ii) if either the Indemnification Representative
     or the Indemnified Persons fail to timely designate an
     arbitrator, the dispute shall be resolved by the one
     arbitrator timely designated.  The Indemnifying Persons and
     the Indemnified Persons shall pay the fees and expenses of
     their respectively designated arbitrators and counsel and
     shall bear equally the fees and expenses of the third
     arbitrator; provided, however, that if the final decision of
     the arbitrators does not award the Indemnified Person at
     least 20% or more of the Contested Amount, Viewlogic shall
     pay the fees and expenses of the Indemnifying Persons'
     designated arbitrator and counsel.  The arbitrators shall
     decide the matter to be arbitrated pursuant hereto within
     thirty (30) days after the appointment of the last
     arbitrator.  The arbitrators' decision shall relate solely
     to whether a claiming Indemnified Person is entitled to
     receive the Contested Amount (or a portion thereof) pursuant
     to the applicable terms of this Agreement.  The final
     decision of the majority of the arbitrators (or of the
     single arbitrator if there is only one arbitrator) shall be
     furnished to the Indemnification Representative, and the
     Indemnified Persons in writing and shall constitute a
     conclusive determination of the issue in question, binding
     upon the Indemnification Representative, the Indemnifying
     Persons, and the Indemnified Persons and shall not be
     contested by any of them.  Such decision may be used in a
     court of law only for the purpose of seeking enforcement of
     the arbitrators' award.

5.5  UNCONTESTED AND RESOLVED CLAIMS.  Claims for Damages which
     are not contested by the Indemnification Representative or
     which have been determined to be payable pursuant to
     Section 5.4 above shall promptly be paid by the Indemnifying
     Persons.  If any amounts in respect of Claims for Damages
     are owed by the Indemnifying Persons to Viewlogic, Viewlogic
     shall have the option of receiving such amounts in cash or
     withholding such amounts from any amounts owing or due from
     Viewlogic to such Holders (including any amount or payments
     required under the Amendment).

5.6  INDEMNIFICATION REPRESENTATIVE.

     (1)  For purposes of this Agreement, the "Indemnification
          Representative" shall be Geoffrey Bunza.  The
          Indemnification Representative shall incur no liability
          with respect to any action taken or suffered by him in
          his capacity as Indemnification Representative in
          reliance upon any note, direction, instruction,
          consent, statement or other documents believed by him
          to be genuinely and duly authorized, nor for other
          action or inaction except his own willful misconduct or
          negligence.  The Indemnification Representative may, in
          all questions arising under this Agreement, rely on the
          advice of counsel and for anything done, omitted or
          suffered in good faith by the

                                  23
<PAGE>

          Indemnification Representative based on such advice, the
          Indemnification Representative shall not be liable to
          anyone.  The Indemnification Representative shall be
          indemnified and saved harmless by the Indemnifying
          Persons from all losses, costs and expenses which he
          may incur as a result of involvement in any legal
          proceedings arising from the performance of his duties
          hereunder.

     (2)  In the event of the death or permanent disability of
          the Indemnification Representative, or his resignation
          as Indemnification Representative, a successor
          Indemnification Representative shall be elected by a
          majority vote of the Indemnifying Persons, with each
          such Indemnifying Person (or his or her successors or
          assigns) to be given a weighted vote based on his pro
          rata entitlement to the Consideration.  Each successor
          Indemnification Representative shall have all of the
          power, authority, rights and privileges conferred by
          this Agreement upon the original Indemnification
          Representative, and the term "Indemnification
          Representative" as used herein shall be deemed to
          include each successor Indemnification Representative.

     (3)  The Indemnification Representative shall have full
          power and authority to represent the Indemnifying
          Persons, and their successors, with respect to all
          matters arising under this Agreement and all action
          taken by the Indemnification Representative hereunder
          shall be binding upon the Indemnifying Persons, and
          their successors, as if expressly confirmed and
          ratified in writing by each of them.  Without limiting
          the generality of the foregoing, the Indemnification
          Representative shall have full power and authority to
          interpret all of the terms and provisions of this
          Agreement, to compromise any claims asserted hereunder
          and to authorize payments to be made with respect
          thereto, on behalf of the Indemnifying Persons and
          their successors.

5.7  SURVIVAL.  The representations and warranties of Eagle and
     the Holders set forth in Articles 2 and 3 of this Agreement
     (as qualified by the Disclosure Schedule) shall survive the
     consummation of the transactions contemplated hereby and
     continue until the last day of the "Third Earnout Year" as
     defined in Section 2 of the Amendment (the "Indemnity
     Period") and shall not be affected by any examination made
     for or on behalf of Viewlogic or the knowledge of any of
     Viewlogic's officers, directors, stockholders, employees or
     agents.  If a notice is given pursuant to this Article 5
     before expiration of such Indemnity Period, then
     (notwithstanding the expiration of such period) the
     representation, warranty, covenant or agreement applicable
     to such claim shall survive until, but only for purposes of,
     the resolution of such claim and all Damages associated with
     or arising from such claim, whether during or after the
     Indemnity Period, shall be borne by the Indemnifying
     Persons.  No Indemnified Person shall be entitled to any
     indemnity hereunder in respect of any claim for
     indemnification first made in writing by an Indemnified
     Person after the Indemnity Period.

5.8  LIMITATION. The liability of each individual Indemnifying
     Person shall be limited to that dollar amount equal to the
     amount of the Consideration received by it, him or her under
     this Agreement plus all amounts received by, or payable to,
     it, him or her under the Amendment.

     other communication hereunder using any other means
     (including personal delivery, expedited courier, messenger
     service, telecopy, telex, ordinary mail, or electronic
     mail), but no such notice, request, demand, claim, or other
     communication shall be deemed to have been duly given unless
     and until it actually is received by the individual for whom
     it is intended.  Any Party may change the address to which
     notices, requests, demands, claims, and other communications
     hereunder are to be delivered by giving the other Parties
     notice in the manner herein set forth.

6.8  GOVERNING LAW.  This Agreement shall be governed by and
     construed in accordance with the internal laws (and not the
     law of conflicts) of the Commonwealth of Massachusetts.

6.9  AMENDMENTS.  No amendment of any provision of this Agreement
     shall be valid unless the same shall be in writing and
     signed by all of the Parties.

6.10 NO WAIVER.  No waiver by any Party of any default,
     misrepresentation, or breach of warranty or covenant
     hereunder, whether intentional or not, shall be deemed to

     hereunder or affect in any way any rights arising by virtue
     of any prior or subsequent such occurrence.

6.11 SEVERABILITY.  Any term or provision of this Agreement that
     is invalid or unenforceable in any situation in any
     jurisdiction shall not affect the validity or enforceability
     of the remaining terms and provisions hereof or the validity
     or enforceability of the offending term or provision in any
     other situation or in any other jurisdiction.  If the final
     judgment of a court of competent jurisdiction declares that
     any term or provision hereof is invalid or unenforceable,
     the Parties agree that the invalid or unenforceable term or
     provision shall be replaced with a term or provision that is
     valid and enforceable and that comes closest to expressing
     the intention of the invalid or unenforceable term or
     provision, and this Agreement shall be enforceable as so
     modified.

6.12 EXPENSES.  Viewlogic shall bear its own costs and expenses
     (including legal, tax and accounting fees and expenses)

     Securities owned by each of them) their own and Eagle's
     costs and expenses (including legal, tax and accounting fees
     and expenses) incurred in connection with this Agreement,
     the performance of their obligations hereunder and the
     transactions contemplated hereby.

6.13 SPECIFIC PERFORMANCE.  Each of the Parties acknowledges and
     agrees that one or more of the other Parties would be
     damaged irreparably in the event any of the provisions of
     this Agreement are not performed in accordance with their
     specific terms or otherwise are breached.  Accordingly, each
     of the Parties agrees that the other Parties shall be
     entitled to an injunction or injunctions to prevent breaches
     of the provisions of this Agreement and to enforce
     specifically this Agreement and the terms and provisions
     hereof in any action instituted in any court of the United
     States or any state thereof having jurisdiction over the
     Parties and the matter, in addition to any other remedy to
     which it may be entitled, at law or in equity.

6.14 INCORPORATION OF EXHIBITS AND SCHEDULES.  The Exhibits and

                          Exhibit B
                          ---------                              
                  NON-COMPETITION AGREEMENT

THIS AGREEMENT (the "Agreement") is entered into as of the
15th day of February, 1997, between Viewlogic Systems, Inc.,
a Delaware corporation with its principal place of business
at 293 Boston Post Road West, Marlboro, Massachusetts 01752,
including it subsidiaries, (the "Company"), and
___________________________________, an individual residing at
______________________________________(the "Shareholder").

                        Introduction
                        ------------                              
     The Company is purchasing all of the capital stock of
Eagle Design Automation, Inc., an Oregon corporation
("Eagle"), of which the Shareholder is a principal
shareholder.  The value of that transaction would be
significantly diminished if the Shareholder were to compete
against the Company in either the businesses conducted by
Eagle or conducted by the Company.  For good and valuable
consideration, the parties agree as follows:
     
     1.   Non-Compete.
          ------------
          1.1   Until the earlier of (i) the fifth
anniversary of the date hereof or (ii) one year after the
termination of Shareholder's employment with the Company,
(the "Non-Compete Period"), the Shareholder will not
directly or indirectly:

               (a)  be employed by, invest in, be a
director, officer or creditor of, provide consulting or
other services to, or otherwise be involved with (other than
as an investor holding less than one percent (1%) of the
total outstanding stock of a publicly held company), any
Direct Competitor of the Company.  For purposes of this
Agreement, the term "Direct Competitor of the Company" shall
mean any business or company, anywhere in the world, engaged
in designing, developing, marketing or selling electronic
design automation ("EDA") products which compete with any
products sold, marketed or the subject of an active
development program by the Company or Eagle at any time
during the period of Shareholder's employment with either
the Company or Eagle.
               
               (b)  recruit, solicit or induce, or attempt
to induce, any employee or employees of the Company or Eagle
to terminate their employment with, or otherwise cease their
relationship with, the Company or Eagle; or
               
               (c)  solicit, divert or take away, or attempt
to solicit, divert or take away, the business or patronage
of any of the clients, customers or accounts, or prospective
clients, customers or accounts of either the Company or
Eagle which were contacted, solicited or served by the
Company or Eagle while Shareholder was employed by the
Company or Eagle.
               
          1.2  The Shareholder and the Company intend that
the agreements set forth in Section 1.1 above shall be
construed as a series of separate covenants, one for each
state, county and other jurisdiction.  Except for geographic
coverage, each such separate covenant shall be deemed
identical in terms to the covenant contained in each clause
of section 1.1 above.  If, in any judicial proceeding, a
court shall refuse to enforce any of the separate covenants
deemed included in Section 1.1 above, then the unenforceable
covenant shall be deemed eliminated from those provisions
for the purpose of those proceedings to the extent necessary
to permit the remaining separate covenants to be enforced.
If any restriction set forth in this Agreement is found by
any court of competent jurisdiction to be unenforceable
because it extends for too long a period of time or over too
great a range of activities or in too broad a

                               30
<PAGE>

geographic area, it shall be interpreted to extend only over 
the maximum period of time, range or activities or geographic
areas as to which it may be enforceable.
          
          1.3  The restrictions contained in this Section 1
are necessary for the protection of the business and
goodwill of the Company and are considered by the
Shareholder to be reasonable for such purpose.  The
Shareholder agrees that any breach of this Section 1 will
cause the Company substantial and irreparable harm and
irrevocable damage and therefore, in the event of any such
breach, in addition to such other remedies which may be
available, the Company shall have the right to obtain
specific performance and injunctive relief.

     2.   Other Agreements.
          -----------------     
     Shareholder hereby represents that he is not bound by
the terms of any agreement with any previous employer or
other party to refrain from using or disclosing any trade
secret or confidential or proprietary information in the
course of his employment with the Company or Eagle or to
refrain from competing, directly or indirectly, with the
business of such previous employer or any other party.
Shareholder further represents that his performance of all
the terms of this Agreement and as an employee of the
Company or Eagle does not and will not breach any agreement
to keep in confidence proprietary information, knowledge or
data acquired by him in confidence or in trust prior to his
employment with the Company or Eagle.
     
     3.     Notices.
            --------
     All notices required or permitted under this Agreement
shall be in writing and shall be deemed effective upon
personal delivery or upon deposit in the United States Post
Office, by registered or certified mail, postage prepaid,
addressed to the other party at the address shown above, or
at such other address or addresses as either party shall
designate to the other in accordance with this Section 3.
     
       4.   Entire Agreement.
            -----------------
     This Agreement constitutes the entire agreement between
the parties and supersedes all prior agreements and
understandings, whether written or oral, relating to the
subject matter hereof.
     

       5.   Amendment.
            ----------
     This Agreement may be amended or modified only by a
written instrument executed by the Company and the
Shareholder.
     
       6.   Governing Law.
            --------------
     This Agreement shall be governed by and construed in
accordance with the internal laws (and not the laws of
conflicts) of the Commonwealth of Massachusetts.
     
       7.   Successors and Assigns.
            -----------------------
     This Agreement shall be binding upon and inure to the
benefit of the parties and their respective successors and
assigns, including any corporation with which or into which
the Company may be merged or which may succeed to its assets
or business; provided, however, that the obligations of the
Shareholder are personal and shall not be assigned.
     
       8.   Miscellaneous.
            --------------

                             31

          8.1  No delay or omission by either party in
exercising any right under this Agreement shall operate as a
waiver of that or any other right.  A waiver or consent
given by either party on any one occasion shall be effective
only in that instance and shall not be construed as a bar or
waiver of any right on any other occasion.
          
          8.2  The captions of the Sections of this
Agreement are for convenience of reference only and in no
way define, limit or affect the scope or substance or any
Section of this Agreement.

          8.3  If any provision of this Agreement is held by
a court of competent jurisdiction to be invalid, void or
unenforceable, the remaining provisions shall nevertheless
continue in full force without being impaired or invalidated
in any way.  If any court of competent jurisdiction holds
any provision of this Agreement to be invalid, void or
unenforceable with respect to any state, region or locality,
such provision shall nevertheless continue in full force and
effect in all other states, regions and localities to which
such provision applies.
          
          8.4  In the event any litigation arises under this
Agreement, promptly upon demand of the prevailing party, the
other party shall reimburse the prevailing party for all
costs and expenses incurred by the prevailing party in
enforcing this Agreement, including without limitation
reasonable attorneys' fees and expenses and applicable court
costs.
          
     IN WITNESS WHEREOF, the parties hereto have executed
this Agreement as of the day and year first above written.

As you are well aware, it is important for Eagle to contain
costs as much as possible in order to become profitable.  In
designing our benefit plan, we have tried to remain
competitive with others within our industry.  In keeping
with this trend, we would like to offer a dental plan that
provides you with a benefit that helps you to reduce your
out-of-pocket dental expenses.  Under this plan, Eagle
Design Automation agrees to pay for dental expenses up to
the maximums listed above. You may use this benefit for any
type of dental or orthodontia work for any member of the
family without having to pay a deductible.  It is important
to understand, however, that the scheduled benefit amounts
are all inclusive. For example, the benefit amount of $550
listed under "EE and Family" is for the entire family, not
$550 per person per family.

Administration:
- --------------
In order to receive this benefit, you must submit a general
Eagle expense report to Jaci Beach along with a copy of your
dental bill complete with services incurred.  You may submit
your expenses as you incur them, or in one lump sum, as long
as you submit them by December 31, 1996.  A check will be
issued to you within 7 days for the amount listed on the
expense report.  PLEASE DO NOT COMBINE OTHER EXPENSES ON THE
SAME EXPENSE REPORT.  It is important for us to keep them
separate in order to be able to track our benefit expenses.

The intent of this policy is for it to be used for dental
reimbursement purposes only and not to be misconstrued as
additional compensation to your base salary.  This policy
will remain in effect until December 31, 1996.  At that
time, we will again review the plan to determine the benefit
plan that provides the employee with the most coverage yet
still remains cost effective for the company.  Eagle
reserves the right to modify, terminate, or change this plan
at that time.
