                          AGREEMENT AND PLAN OF MERGER

          THIS AGREEMENT AND PLAN OF MERGER, dated as of December 3, 2001 (the
"Agreement") is among Synopsys, Inc., a Delaware corporation ("Parent"), Maple
Forest Acquisition L.L.C., a Delaware limited liability company and a direct
wholly-owned subsidiary of Parent ("Merger Sub"), and Avant! Corporation, a
Delaware corporation (the "Company").

          WHEREAS, the Boards of Directors of Parent and the Company, and Parent
(in its capacity as sole member of Merger Sub), have each determined that this
Agreement and the transactions contemplated hereby, including the Merger (as
defined in Section 1.1), are advisable and fair to, and in the best interests
of, their respective stockholders or (in the case of Merger Sub) member;

          WHEREAS, for United States federal income tax purposes, the Parties
intend that the Merger shall qualify as a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code");

          WHEREAS, in order to induce Parent and Merger Sub to enter into this
Agreement, and as a condition to their doing so, Parent is simultaneously
entering into stockholder agreements (collectively, the "Voting Agreements")
with the Company's directors and executive officers owning shares of Company
Common Stock (as defined in Section 2.1(c)), pursuant to which such stockholders
are agreeing, among other things, to vote in favor of the Merger;

          WHEREAS, in order to induce Parent and Merger Sub to enter into this
Agreement, and as a condition to their doing so, certain executive officers and
other persons affiliated with the Company are simultaneously entering into new
employment agreements and other agreements with Parent or the Company to become
effective at the Effective Time (as defined in Section 1.2)

          NOW, THEREFORE, in consideration of the premises and the
representations, warranties, covenants and agreements herein contained, and
intending to be legally bound hereby, the Company, Parent and Merger Sub hereby
agree as follows:

                                   ARTICLE I

                                   THE MERGER

          1.1. The Merger. At the Effective Time, upon the terms and subject to
the conditions of this Agreement and in accordance with the General Corporation
Law of the State of Delaware (the "DGCL") and the Delaware Limited Liability
Company Act (the "DLLCA" ), the Company shall be merged with and into Merger Sub
(the "Merger"). Following the Merger, Merger Sub shall continue as the surviving
company (the "Surviving Company") and shall continue its existence under the
DLLCA, and the separate corporate existence of the Company shall cease.

          1.2. Effective Time. Subject to the provisions of this Agreement,
Parent, Merger Sub and the Company shall cause the Merger to be consummated by
filing a certificate of merger complying with Section 264 of the DGCL, and with
Section 18-209 of the DLLCA, with the Secretary of State of the State of
Delaware (the "Certificate of Merger") on the Closing Date (as defined in
Section 1.3). The Merger shall become effective upon such filing or at such time
thereafter as the parties shall agree and as shall be provided in the
Certificate of Merger (the "Effective Time").

          1.3. Closing of the Merger. The closing of the Merger (the "Closing")
will take place at a time and on a date (the "Closing Date") to be specified by
Parent, which shall be no later than the fifth Business Day (as defined in
Section 9.11(d)) after satisfaction or waiver of the conditions set forth in
Article VII (other than those conditions that by their nature are to be
satisfied at the Closing, but subject to the fulfillment or waiver of those
conditions), at the offices of Parent (or such other location to be specified by
Parent), unless another time or date is agreed to in writing by the parties
hereto.

          1.4. Effects of the Merger. The Merger shall have the effects set
forth in the DGCL and the DLLCA. Without limiting the generality of the
foregoing, and subject thereto, at the Effective Time, all the properties,
rights, privileges, immunities, powers and franchises of the Company and Merger
Sub shall vest in the Surviving Company, and all debts, liabilities, obligations
and duties of the Company and Merger Sub shall become the debts, liabilities,
obligations and duties of the Surviving Company.

          1.5. Certificate of Formation; Limited Liability Company Agreement.
The limited liability company agreement of Merger Sub in effect immediately
prior to the Effective Time shall, by virtue of the Merger, be amended and
restated as of the Effective Time to reflect the fact that the name of the
Surviving Company, from and after the Effective Time, shall be "Avant! Company,"
and as so amended and restated, such limited liability company agreement shall
(as amended by Parent, as sole member, from time to time) be the limited
liability company agreement of the Surviving Company. The certificate of
formation of Merger Sub in effect immediately prior to the Effective Time shall
be the certificate of formation of the Surviving Company and shall be amended in
due course to reflect the fact that the name of the Surviving Company, from and
after the Effective Time, shall be "Avant! Company."

          1.6. Sole Member. Parent shall be the sole member of the Surviving
Company.

          1.7. Officers. The officers of Merger Sub immediately prior to the
Effective Time shall be the officers of the Surviving Company, each to hold
office in accordance with the limited liability company agreement of the
Surviving Company until successors are duly elected or appointed and qualified.

          1.8. Structure. Notwithstanding any other provision of this Agreement,
at Parent's election (exercised in its sole discretion) the structure of the
Merger shall be revised to provide for a newly organized Delaware corporation,
whose sole stockholder shall be Parent, to merge with and into the Company, and
the Parties shall enter into an amendment to this Agreement effecting such
revised structure; provided that any such revised structure and amendment does
not (x) alter the Exchange Ratio or the Merger Consideration or (y) prevent or
materially delay the consummation of the Merger or (z) prevent satisfaction of
the conditions set forth in Sections 7.2(d) and 7.3(d).

                                   ARTICLE II

                            CONVERSION OF SECURITIES

          2.1. Conversion of Securities. At the Effective Time, by virtue of the
Merger and without any action on the part of any of the parties hereto or any
holder of any securities or interests of or in the Company or Merger Sub:

          (a) Limited Liability Company Interests in Merger Sub. Each limited
liability company interest in Merger Sub outstanding immediately prior to the
Effective Time shall remain outstanding upon the Merger.

          (b) Cancellation of Treasury Shares and Parent-Owned Shares. Each
share of Company Common Stock (as defined in Section 2.1(c)) issued and
outstanding immediately prior to the Effective Time that is owned by the Company
or Parent or any of their respective wholly-owned subsidiaries shall
automatically be cancelled and shall cease to exist, and no consideration shall
be delivered or deliverable in exchange therefor.

          (c) Conversion of Company Common Stock. Each share of common stock,
par value $.0001 per share, of the Company ("Company Common Stock") issued and
outstanding immediately prior to the Effective Time (individually, a "Share" and
collectively, the "Shares") (other than Shares to be cancelled in accordance
with Section 2.1(b)) shall be converted into and be exchangeable for the right
to receive .371 (the "Exchange Ratio") of a fully paid and non-assessable share
of common stock, par value $.01 per share, of Parent (including the associated
rights (the "Parent Rights") to purchase shares of Series A Participating
Preferred Stock pursuant to the Parent Rights Agreement (as defined in Section
9.11) ("Parent Common Stock") (all such shares of Parent Common Stock issued,
together with any cash in lieu of fractional shares of Parent Common Stock to be
paid pursuant to Section 2.7, being referred to as the "Merger Consideration").

          (d) Certain Adjustments. If between the date of this Agreement and the
Effective Time the outstanding shares of Parent Common Stock shall have been
changed into a different number of shares or a different class by reason of any
stock dividend, subdivision, reclassification, recapitalization, split,
combination or exchange of shares or any similar event, the fraction of a share
of Parent Common Stock constituting the Exchange Ratio shall be appropriately
adjusted to reflect such stock dividend, subdivision, reclassification,
recapitalization, split, combination or exchange of shares or such similar
event.

          2.2. Stock Options and Other Stock Plans. (a) As soon as practicable
following the date of this Agreement, Parent and the Company (or, if
appropriate, the Board of Directors of the Company or any committee of the Board
of Directors of the Company administering the Company's 2000 Stock Option/Stock
Issuance Plan (the "2000 Plan") , the Company's 1995 Stock Option/Stock Issuance
Plan (the "1995 Plan") , the Chrysalis Symbolic Design, Inc. 1993 Stock Option

Plan, the Technology Modeling Associates, Inc. 1989 Stock Option Plan, the

Stock Option Plan, the Arcsys, Inc. 1993 Stock Option/Stock Issuance Plan and
the Anagram, Inc. 1993 Stock Incentive Plan (collectively, the "Company Option
Plans")) shall take such action as may be required or desirable (including
obtaining all applicable consents) to effect the following provisions of this
Section 2.2(a). Except as may otherwise be provided in any agreement on terms
specified in Section 2.2(a) of the Company Disclosure Schedule, effective as of
the Effective Time (i) each then outstanding option to purchase Shares (each a
"Company Stock Option") granted pursuant to the Company Stock Plans or otherwise
granted by the Company to any current or former employee or director of, or
consultant to, the Company or any of its subsidiaries (each, an "Option Holder")
shall be assumed by Parent and shall be converted into an option (an "Assumed
Stock Option") to purchase a number of shares of Parent Common Stock (rounded
down to the nearest whole share) equal to (x) the number of Shares subject to
such Company Stock Option immediately prior to the Effective Time multiplied by
(y) the Exchange Ratio and (ii) the per share exercise price for shares of
Parent Common Stock issuable upon exercise of such Assumed Stock Option shall be
equal to (1) the exercise price per share of Company Common Stock at which such
Company Stock Option was exercisable immediately prior to the Effective Time
divided by (2) the Exchange Ratio; provided, however, that in the case of any
Company Stock Option to which Section 421 of the Code applies by reason of its
qualification under Section 422 of the Code, the conversion formula shall be
adjusted, if necessary, to comply with Section 424(a) of the Code. Except as
otherwise provided herein, the Assumed Stock Option shall be subject to the same
terms and conditions (including expiration date, vesting and exercise
provisions) as were applicable to the corresponding Company Stock Options
immediately prior to the Effective Time; provided, that the Parent Board of
Directors or a committee thereof shall succeed to the authority and
responsibility of the Company Board of Directors or any committee thereof; and
provided, further that each Company Stock Option granted to an Eligible Director
(as defined in the 1995 Plan) under the 1995 Plan shall not be assumed and
converted and shall vest in full immediately prior to the Effective Time, in
accordance with the terms of the 1995 Plan.

          (b) With respect to Company Stock Options granted under the Company
Option Plans pursuant to which consent of an Option Holder is required, if any,
as identified in Section 2.2(b) of the Company Disclosure Schedule, no later
than the Effective Time, the Company will obtain a signed written consent from
each Option Holder to the treatment of the Company Stock Options in the manner
described in Section 2.2(a) hereof. As soon as practicable after the Effective
Time, Parent shall deliver to the Option Holders appropriate notices setting
forth the number of shares subject to such Assumed Stock Options held by each
such Option Holder and the exercise price under each such Assumed Stock Option,
each as adjusted pursuant to Section 2.2(a) hereof, and stating that such
Assumed Stock Options shall remain subject to the original terms and conditions
applicable to the corresponding Company Stock Option as in effect immediately
prior to the Effective Time (subject to the adjustments required by this Section
2.2).

          (c) As soon as reasonably practicable following the Effective Time,
Parent shall take such actions as are reasonably necessary to reserve for
issuance a sufficient number of shares of Parent Common Stock upon the exercise
of the Assumed Stock Options. Parent shall use its best efforts to prepare and
file with the Securities and Exchange Commission (the "SEC") a registration
statement on Form S-8 or other appropriate form with respect to the shares of
Parent Common Stock subject to the Assumed Stock Options and to maintain the
effectiveness of such registration statement or registration statements covering
such Assumed Stock Options (and maintain the current status of the prospectus or
prospectuses contained therein) for so long as such Assumed Stock Options remain
outstanding.

          (d) Prior to the Effective Time, the Company shall take all necessary
or appropriate action (including amending any of the Company Option Plans and
related award agreements or making adjustments as permitted thereby) to (i)
effectuate the assumption and conversion of the Company Stock Options by Parent
in accordance with the terms hereof and the assignment to Parent of the
authorities and responsibilities of the Company Board or any committee thereof
under the Company Option Plans and (ii) except as permitted under Section 2.2(d)
of the Company Disclosure Schedule, preclude the grant of any additional options
or other awards of any type under any of the Company Option Plans or otherwise.

          (e) The Company shall take such action as is necessary to (i) cause
the exercise (as of a date that is no later than three Business Days prior to
the Effective Date) of each outstanding purchase right under the Company's
Employee Stock Purchase Plan, the Technology Modeling Associates, Inc. 1996
Employee Stock Purchase Plan, and the Meta-Software, Inc. 1995 Employee Stock
Purchase Plan, as applicable, (the "Company Stock Purchase Plans"); and (ii)
provide that no further purchase period shall commence under such plans;
provided, that such exercise and cessation of further purchase periods shall be
conditioned upon the consummation of the Merger. On such new exercise date, the
Company shall apply the funds credited as of such date under the applicable
Company Stock Purchase Plan within each participant's payroll withholding
account to the purchase of whole shares of Company Common Stock in accordance
with the terms of the applicable Company Stock Purchase Plan. At the Effective
Time, a holder of such Shares received under the Company Stock Purchase Plans
shall, by virtue of the Merger and without any action on the part of such
holder, be entitled to receive the Merger Consideration (subject to any
applicable withholding tax as specified in Section 2.12 hereof or as may apply
to payments made in connection with the performance of services), upon the
surrender of the certificate representing such Shares as provided in Section
2.4. Immediately prior to and effective as of the Effective Time and subject to
the consummation of the Merger, the Company shall terminate the Company Stock
Purchase Plans.

          2.3. Exchange Fund. (a) Prior to the Effective Time, Parent shall
appoint a commercial bank or trust company reasonably acceptable to the Company
to act as exchange agent hereunder for the purpose of exchanging Shares for the
Merger Consideration (the "Exchange Agent").

          (b) At or prior to the Effective Time, Parent shall deposit, or cause
to be deposited, with the Exchange Agent, in trust for the benefit of holders of
Shares, the Merger Consideration issuable pursuant to Section 2.1 in exchange
for outstanding Shares. Parent agrees to make available to the Exchange Agent
from time to time as needed, cash sufficient to pay cash in lieu of fractional
shares pursuant to Section 2.7 and any dividends and other distributions
pursuant to Section 2.5. Any cash or Parent Common Stock deposited with the
Exchange Agent pursuant to this Section 2.3(b) shall hereinafter be referred to
as the "Exchange Fund."

          2.4. Exchange Procedures. As soon as reasonably practicable after the
Effective Time, the Surviving Company shall cause the Exchange Agent to mail to
each holder of record, as of the Effective Time, of a certificate or
certificates which immediately prior to the Effective Time represented
outstanding Shares (the "Certificates") whose Shares were converted into the
right to receive Parent Common Stock pursuant to Section 2.1(c) (i) a form of
letter of transmittal (which shall specify that delivery shall be effective, and
risk of loss and title to the Certificates shall pass, only upon proper delivery
of the Certificates to the Exchange Agent, and which letter shall be in
customary form and have such other provisions as Parent may reasonably specify)
and (ii) instructions for effecting the surrender of such Certificates in
exchange for the applicable Merger Consideration. Upon surrender of a
Certificate to the Exchange Agent together with such letter of transmittal, duly
completed and validly executed in accordance with the instructions thereto, and
such other documents as may reasonably be required by the Exchange Agent, the
holder of such Certificate shall be entitled to receive in exchange therefor
shares of Parent Common Stock representing, in the aggregate, the whole number
of shares that such holder has the right to receive pursuant to Section 2.1(c)
(after taking into account all Shares then held by such holder) and (B) a check
in the amount equal to the cash that such holder has the right to receive (x) in
lieu of any fractional shares of Parent Common Stock pursuant to Section 2.7 and
(y) in respect of any dividends and other distributions payable pursuant to
Section 2.5. No interest will be paid or will accrue on any cash payable
pursuant to this Article II and the certificates so surrendered shall forthwith
be cancelled. In the event of a transfer of ownership of Company Common Stock
which is not registered in the transfer records of the Company, shares of Parent
Common Stock evidencing, in the aggregate, the proper number of shares of Parent
Common Stock, cash in lieu of any fractional shares of Parent Common Stock
pursuant to Section 2.7 and any dividends or other distributions to which such
holder is entitled pursuant to Section 2.5, may be issued and paid with respect
to such Shares to such a transferee if the Certificate representing such Shares
is presented to the Exchange Agent, accompanied by all documents required to
evidence and effect such transfer and to evidence that any applicable stock
transfer Taxes have been paid.

          2.5. Distributions with Respect to Unsurrendered Certificates. From
and after the Effective Time and until surrendered in accordance with the
provisions of this Article II, each Certificate (other than Certificates for
Shares to be cancelled pursuant to Section 2.1(b)) shall represent for all
purposes solely the right to receive in accordance with the terms hereof, the
Merger Consideration. No dividends or other distributions declared or made with
respect to shares of Parent Common Stock with a record date after the Effective
Time shall be paid to the holder of any unsurrendered Certificate representing
Shares of Company Common Stock with respect to the shares of Parent Common Stock
that such holder would be entitled to receive upon surrender of such Certificate
and no cash payment in lieu of fractional shares of Parent Common Stock shall be
paid to any such holder pursuant to Section 2.7 until such holder shall
surrender such Certificate in accordance with Section 2.4. Subject to the effect
of applicable Laws (as defined in Section 3.9), following surrender of any such
Certificate, there shall be paid to such holder of shares of Parent Common Stock
issuable in exchange therefor, without interest, (i) promptly after the time of
such surrender, the amount of any cash payable in lieu of fractional shares of
Parent Common Stock to which such holder is entitled pursuant to Section 2.7 and
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 Stock and (ii) at the appropriate payment date, the amount of dividends
or other distributions with a record date after the Effective Time but prior to
such surrender and a payment date subsequent to such surrender payable with
respect to such shares of Parent Common Stock.

          2.6. No Further Ownership Rights. All shares of Parent Common Stock
and issued upon conversion of the Shares in accordance with the terms of this
Article II, and any cash paid pursuant to Sections 2.5 and 2.7, shall be deemed
to have been issued or paid in full satisfaction of all rights pertaining to the
Shares.

          2.7. No Fractional Shares of Parent Common Stock. (a) No certificates
or scrip of shares of Parent Common Stock representing fractional shares of
Parent Common Stock or book-entry credit of the same shall be issued upon the
surrender for exchange of Certificates and such fractional share interests will
not entitle the owner thereof to vote or to have any rights of a stockholder of
Parent or a holder of shares of Parent Common Stock.

          (b) Notwithstanding any other provision of this Agreement, each holder
of Shares exchanged pursuant to the Merger who would otherwise have been
entitled to receive a fraction of a share of Parent Common Stock (after taking
into account all Certificates delivered by such holder) shall receive, in lieu
thereof, cash (without interest) in an amount equal to the product of (i) such
fractional part of a share of Parent Common Stock multiplied by (ii) the average
of the closing prices during regular trading hours (as reported in the New York
City edition of The Wall Street Journal or, if not reported thereby, another
nationally recognized source) for a share of Parent Common Stock on the three
trading days immediately prior to the day on which the Effective Time occurs. As
promptly as practicable after the determination of the aggregate amount of cash
to be paid to holders of fractional interests, the Exchange Agent shall notify
Parent and Parent shall deposit such amount with the Exchange Agent and shall
cause the Exchange Agent to forward payments to such holders of fractional
interests subject to and in accordance with the terms hereof.

          2.8. Termination of Exchange Fund. Any portion of the Exchange Fund
(including any income or proceeds thereof or of any investments thereof) which
remains undistributed to the holders of Certificates for six months after the
Effective Time shall be delivered to Parent or otherwise on the instruction of
Parent, and any holders of the Certificates who have not theretofore complied
with this Article II shall thereafter look only to the Surviving Company and
Parent (subject to abandoned property, escheat and similar laws) for the Merger
Consideration exchangeable for such Certificates to which such holders are
entitled, any cash in lieu of fractional shares of Parent Common Stock to which
such holders are entitled pursuant to Section 2.7 and any dividends or
distributions with respect to shares of Parent Common Stock to which such
holders are entitled pursuant to Section 2.5, without any interest on any
thereof. Any such portion of the Exchange Fund remaining unclaimed by holders of
Shares two years after the Effective Time (or such earlier date as shall be
immediately prior to such date as such securities or amounts would otherwise
escheat to or become property of any Governmental Entity (as defined in Section
3.8)) shall, to the extent permitted by Law, become the property of Parent, free
and clear of any claims or interest of any person previously entitled thereto.

          2.9. No Liability. None of Parent, Merger Sub, the Company, the
Surviving Company or the Exchange Agent shall be liable to any person in respect
of any Merger Consideration from the Exchange Fund delivered to a public
official pursuant to any applicable abandoned property, escheat or similar Law.

          2.10. Investment of the Exchange Funds. The Exchange Agent shall
invest any cash included in the Exchange Fund as directed by Parent on a daily
basis. Any interest and other income resulting from any such investment shall
promptly be paid to Parent.

          2.11. Lost Certificates. If any Certificate 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 and, if required by
the Surviving Company, the posting by such person of a bond in such reasonable
amount as the Surviving Company may direct as indemnity against any claim that
may be made against it with respect to such Certificate, the Exchange Agent will
deliver in exchange for such lost, stolen or destroyed Certificate the
applicable Merger Consideration with respect to the Shares formerly represented
thereby and any unpaid dividends and distributions on shares of Parent Common
Stock deliverable in respect thereof, pursuant to this Agreement, without any
interest thereon.

          2.12. Withholding Rights. Each of the Surviving Company and Parent
shall be entitled to deduct and withhold from the Merger Consideration otherwise
payable pursuant to this Agreement to any holder of Shares of such amounts as it
is required to deduct and withhold with respect to the making of such payment
under the Code and the rules and regulations promulgated thereunder, or any
provision of a Tax Law (as the term "Tax" is defined in Section 3.16(n) hereof).
To the extent that amounts are so withheld by the Surviving Company or Parent,
as the case may be, 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 by the Surviving Company or
Parent, as the case may be.

          2.13. Stock Transfer Books. The stock transfer books of the Company
shall be closed immediately upon the Effective Time and there shall be no
further registration of transfers of Shares thereafter on the records of the
Company. On or after the Effective Time, any Certificates presented to the
Exchange Agent or Parent for any reason shall, subject to Section 2.8, be
converted into the Merger Consideration with respect to the Shares formerly
represented thereby, any cash in lieu of fractional shares of Parent Common
Stock to which the holders thereof are entitled pursuant to Section 2.7 and any
dividends or other distributions to which the holders thereof are entitled
pursuant to Section 2.5.

          2.14. Affiliates. Notwithstanding anything to the contrary herein, no
Merger Consideration shall be delivered to a person who may be deemed an
"affiliate" of the Company in accordance with Section 6.10 hereof for purposes
of Rule 145 under the Securities Act of 1933, as amended (the "Securities Act"),
until such person has executed and delivered to Parent the written agreement
contemplated by Section 6.10.

                                  ARTICLE III

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

          Except as set forth in the section of the disclosure schedule
delivered by the Company to Parent prior to the execution of this Agreement (the
"Company Disclosure Schedule") that specifically relates to the correspondingly
numbered section of this Article III, the Company hereby represents and warrants
to each of Parent and Merger Sub as follows:

          3.1. Organization and Qualification; Subsidiaries. (a) The Company and
each of its subsidiaries is a corporation or legal entity duly organized,
validly existing and (in those jurisdictions in which there is an applicable
concept of good standing) in good standing under the Laws of the jurisdiction of
its organization and has all requisite corporate, partnership or similar power
and authority to own, lease and operate its properties and to carry on its
businesses as now conducted.

          (b) Section 3.1 of the Company Disclosure Schedule sets forth (i) a
list of all subsidiaries of the Company, (ii) in the case of such subsidiaries
not wholly-owned by the Company (A) the identity of any other entity or person
that owns, directly or indirectly, beneficially or of record, any shares of
capital stock or other security, or any option to purchase any shares of capital
stock or other security, or any other investment in such entity (and all rights,
privileges and preferences of any such beneficial or record holder with respect
thereto, including repurchase rights, put rights, cancellation rights, co-sale
rights, registration rights or other rights affecting the shares or options held
by such third party), (B) the percentage ownership represented by such
investment and (C) with regard to the entity in which such investment is held,
all jurisdictions where such entities conduct business or own assets. The
Company does not own, directly or indirectly, beneficially or of record, any
shares of capital stock or other security of any other entity or any other
investment in any entity that is not listed on Section 3.1(b) to the Company
Disclosure Schedule.

          (c) The Company and each of its subsidiaries is duly qualified or
licensed and in good standing to do business in each jurisdiction in which the
property owned, leased or operated by it or the nature of the business conducted
by it makes such qualification or licensing necessary, except where the failure
to be so duly qualified or licensed and (in those jurisdictions in which there
is an applicable concept of good standing) in good standing has not had, and
would not have, individually or in the aggregate, a Material Adverse Effect (as
defined in Section 9.11) on the Company.

          (d) The Company has heretofore delivered or made available to Parent
accurate and complete copies of the articles or certificate of incorporation and
bylaws or other similar organizational documents, as currently in effect, of (i)
the Company and (ii) each of its material subsidiaries.

          3.2. Capitalization of the Company and Its Subsidiaries. (a) The

outstanding options described in the second sentence of this Section 3.2 will
be, when issued in accordance with the terms thereof, duly authorized, validly
issued, fully paid and non-assessable. From the Capitalization Date through the
date hereof, there have been no issuances of shares of the capital stock or
other securities of the Company or of options, warrants or rights with respect
to shares of Company Common Stock or other securities of the Company, other than

there are no shares of capital stock of the Company authorized, issued or
outstanding, (2) there are no authorized or outstanding options, warrants,
calls, preemptive rights, subscriptions or other rights, agreements,
arrangements or commitments of any character (whether or not conditional)
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,
transfer or sell or cause to be issued, transferred or sold any shares of
capital stock or other equity interest in the Company of any of its subsidiaries
or securities convertible into or exchangeable for such shares or equity
interests, or obligating the Company or any of its subsidiaries to grant, extend
or enter into any such option, warrant, call, subscription or other right,
agreement, arrangement or commitment, (3) there are no outstanding contractual
obligations of the Company or any of its subsidiaries to repurchase, redeem or
otherwise acquire any Shares or other capital stock of the Company or any of its

wholly-owned subsidiaries in the ordinary course of business, and (4) there are
no outstanding shareholder agreements, voting agreements, option agreements,
buy-sell agreements, rights of first refusal or first offer, registration rights
agreements or other similar agreements with respect to the equity securities of
any subsidiary.

          (b) All of the capital stock of the Company's subsidiaries owned by
the Company, directly or indirectly, is free and clear of any Lien or any other
limitation or restriction (including any restriction on the right to vote or
sell the same, except as may be provided as a matter of Law), and there are no
irrevocable proxies with respect to such capital stock. For purposes of this
Agreement, "Lien" means, with respect to any asset (including, without
limitation, any security) any mortgage, lien, pledge, charge, security interest
or encumbrance of any kind in respect of such asset.

          (c) The consummation of the Merger and the transactions contemplated
hereby will not trigger, and neither the Company nor the Board (nor any
committee thereof) shall take any action to cause with respect to any Company
Stock Options, (x) the acceleration of vesting provisions of or (y) the
termination of any rights by the Company to repurchase any outstanding option to
buy Company Shares, except, in the case of each of clauses (x) and (y), as
required by the 2000 Plan, the 1995 Plan and the other agreements set forth
(together with the identities of the holders of the Company Stock Options so
subject to acceleration or termination and the number of such Options) in
Section 3.2(c) of the Company Disclosure Schedule.

          3.3. Authority Relative to This Agreement. (a) The Company has all
necessary corporate power and authority to execute and deliver this Agreement
and to consummate the transactions contemplated hereby. The Board of Directors
of the Company (the "Company Board") has, by unanimous vote of those present
(who constituted all of the directors then in office), duly and validly
authorized the execution, delivery and performance of this Agreement and
approved the consummation of the transactions contemplated hereby, and taken all
corporate actions required to be taken by the Company Board for the consummation
of the transactions, including the Merger, contemplated hereby, and has (i) by
resolution approved, and declared advisable, the agreement of merger (within the
meaning of Section 251 of the DGCL) contained within this Agreement; (ii)
determined that such transactions are advisable and fair to, and in the best
interests of, the Company and its stockholders; and (iii) resolved to recommend
that the stockholders of the Company approve and adopt such agreement of merger.
Such Company Board action reflected the unanimous recommendation of the Special
Committee of Independent Directors established by the Company Board. No other
corporate proceedings on the part of the Company are necessary to authorize this
Agreement or to consummate the transactions contemplated hereby (other than,
with respect to the Merger and the agreement of merger (within the meaning of
Section 251 of the DGCL contained within this Agreement), the Required Company
Vote (as defined in Section 3.3(b) herein)). This Agreement has been duly and
validly executed and delivered by the Company and constitutes a valid, legal and
binding agreement of the Company, enforceable against the Company in accordance
with its terms.

          (b) The Company Board has directed that the agreement of merger
contained within this Agreement be submitted to the stockholders of the Company
for their approval at a meeting to be held for that purpose. The affirmative
vote of the holders of a majority of the outstanding Company Common Stock as of
the record date for the Company Stockholders Meeting (as hereinafter defined)
(the "Required Company Vote") is the only vote of the holders of any class or
series of capital stock of the Company necessary to adopt the agreement of
merger contained within this Agreement and approve the transactions contemplated
hereby, including the Merger.

          3.4. SEC Reports; Financial Statements. (a) The Company has timely
filed all required forms, reports and documents with the SEC since January 1,
1998, each of which has complied in all material respects with all applicable
requirements of the Securities Act and the Securities Exchange Act of 1934, as

and documents were filed. No subsidiary of the Company has filed, or is required
to file, any form, report or other document with the SEC. The Company has
heretofore (x) delivered or made available to Parent all correspondence with the
SEC since January 1, 1999 and prior to the date hereof and (y) made available to

"Company SEC Reports"). None of such forms, reports or documents, including,
without limitation, any financial statements, exhibits or schedules included or
incorporated by reference therein, contained, when filed, any untrue statement
of a material fact or omitted to state a material fact required to be stated or
incorporated by reference therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading.

          (b) The audited and unaudited consolidated financial statements of the
Company included (or incorporated by reference) in the Company SEC Reports
complied as to form in all material respects with applicable accounting
requirements and the published rules and regulations of the SEC with respect
thereto and fairly present, in conformity with U.S. generally accepted
accounting principles applied on a consistent basis ("GAAP") (except as

thereof and their consolidated results of operations and changes in financial
position for the periods then ended (subject, in the case of the unaudited
interim financial statements, to normal year-end adjustments that have not been,
and will not be, material in amount). The Company has furnished Parent with its
good faith estimate, as of the date hereof, of aggregate orders and revenues for
the quarter ending December 31, 2001.

          3.5. No Undisclosed Liabilities. Neither the Company nor any of its
subsidiaries has any liabilities or obligations of any nature, whether accrued,
contingent or otherwise, and whether or not required to be recorded or reflected
on a balance sheet under GAAP, except (a) liabilities or obligations reflected
in the financial statements in the Company SEC Reports filed prior to the date

the aggregate, a Material Adverse Effect on the Company and (c) liabilities or
obligations (of a type and in amounts consistent with those set forth on Section
3.5 of the Company Disclosure Schedule) incurred in connection with the
transactions contemplated hereby (including the liabilities described in Section

Tax election by the Company or any subsidiary of the Company, any settlement or
compromise of any Tax Liability of the Company or any subsidiary of the Company,

registration statement on Form S-4 to be filed with the SEC by Parent in
connection with the issuance of Parent Common Stock as required by the terms of
this Agreement (the "Share Issuance") pursuant to the Merger (the "S-4") at the
time the S-4 is filed with the SEC and at the time it becomes effective under
the Securities Act, will contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make
the statements therein not misleading, and (ii) the joint proxy statement
relating to the Company Stockholder Meeting (as hereinafter defined) and the
Parent Stockholder Meeting (as hereinafter defined) to be held in connection
with the Merger and the Share Issuance (the "Proxy Statement") will, at the date

held in connection with the Merger or the Share Issuance, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they are made, not misleading. If at any time
prior to the Effective Time, any event with respect to the Company, its officers
and directors or any of its subsidiaries should occur which is required to be
described in an amendment of, or a supplement to, the S-4 or the Proxy
Statement, the Company shall promptly so advise Parent and such event shall be
so described, and such amendment or supplement (which Parent shall have a
reasonable opportunity to review) shall be promptly filed with the SEC and, to
the extent required by Law, disseminated to the stockholders of the Company. The
Proxy Statement, insofar as it relates to the Company Stockholder Meeting, will
comply as to form in all material respects with the provisions of the Exchange
Act and the rules and regulations thereunder.

          3.8. Consents and Approvals; No Violations. (a) Except for filings,

Entity") is necessary for the execution and delivery by the Company of this
Agreement or the consummation by the Company of the transactions contemplated
hereby, except where the failure to obtain such permits, authorizations,
consents or approvals or to make such filings or give such notice does not have,
and would not have, individually or in the aggregate, a Material Adverse Effect
on the Company.

          (b) Neither the execution, delivery and performance of this Agreement
by the Company nor the consummation by the Company of the transactions
contemplated hereby will (i) conflict with or result in any breach of any
provision of the respective articles or certificate of incorporation or bylaws
(or similar governing documents) of the Company or any of its subsidiaries, (ii)
result in a violation or breach of, or constitute (with or without due notice or
lapse of time or both) a default (or give rise to any right of termination,

material benefit, or the creation of any Lien) under any of the terms,
conditions or provisions of any material note, bond, mortgage, indenture, lease,
license, contract, agreement or other instrument or obligation to which the
Company or any of its subsidiaries is a party or by which any of them or any of
their respective properties or assets may be bound (collectively, the "Company
Agreements") or (iii) violate any Law applicable to the Company or any of its
subsidiaries or any of their respective properties or assets, except in the case
of each of clauses (ii) and (iii) for any violations, breaches or defaults which
do not have, and would not have, individually or in the aggregate, a Material
Adverse Effect on the Company. Section 3.8 of the Company Disclosure Schedule
sets forth a list of all material third party consents and approvals required to
be obtained under the Company Agreements in connection with the consummation of
the transactions contemplated by this Agreement.

          3.9. No Default. Except to the extent disclosed by the Company in

its subsidiaries is in violation in any material respect of any term of (i) its
articles or certificate of incorporation, bylaws or other organizational
documents, (ii) any agreement or instrument related to indebtedness for borrowed
money or any other material agreement to which it is a party or by which it is
bound, or (iii) any foreign or domestic law, order, writ, injunction, decree,
ordinance, award, stipulation, statute, judicial or administrative doctrine,
rule or regulation entered by a Governmental Entity ("Law") applicable to the
Company, its subsidiaries or any of their respective properties or assets,
except in the case of each of clauses (ii) and (iii) above, for violations which
do not have, and would not have, individually or in the aggregate, a Material
Adverse Effect on the Company.

          3.10. Real Property. (a) Neither the Company nor any of its
subsidiaries owns any real property.

          (b) Section 3.10 of the Company Disclosure Schedule sets forth all
leases, subleases and other agreements (the "Real Property Leases") under which
the Company or any of its subsidiaries uses, occupies or sublets or has the
right to use, occupy or sublet now or in the future, any real property. The
Company has heretofore delivered or made available to Parent true, correct and
complete copies of all Real Property Leases (and all modifications, amendments
and supplements thereto and all side letters to which the Company or any of its
subsidiaries is a party affecting the obligations of any party thereunder). Each
Real Property Lease constitutes the valid and legally binding obligation of the
Company or its subsidiaries, enforceable in accordance with its terms (except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, fraudulent transfer and similar Laws of general
applicability relating to or affecting creditors' rights or by general equity
principles), and is in full force and effect. All rent and other sums and
charges payable by the Company and its subsidiaries as tenants, or payable to
the Company or any of its subsidiaries as sublessor, under each Real Property
Lease are current, no termination event or condition or uncured default of a
material nature on the part of the Company or any such subsidiary of the Company
or, to the Company's knowledge, the landlord or the sublessee, as the case may
be, exists under any Real Property Lease. Each of the Company and its
subsidiaries has a good and valid leasehold interest in each parcel of real
property leased by it free and clear of all Liens, except (i) Liens for Taxes
and general and special assessments not in default and payable without penalty
and material interest and (ii) other liens, mortgages, pledges, encumbrances and
security interests which do not materially interfere with the Company's or any
of its subsidiaries' use and enjoyment of such real property or materially
detract from or diminish the value thereof.

          (c) No party to any Real Property Lease has given notice to the
Company or any of its subsidiaries of or made a claim against the Company or any
of its subsidiaries to the Company or any of its subsidiaries with respect to
any material breach or default thereunder and the Company has no knowledge of
any such claim.

          3.11. Litigation. (a) Except as and to the extent disclosed in the
Company SEC Reports filed prior to the date hereof or in Section 3.11(a) of the
Company Disclosure Schedule, there is no suit, claim, action, proceeding or
investigation pending or, to the Company's knowledge, threatened against the
Company or any of its subsidiaries or any of their respective properties or
assets.

          (b) Except to the extent disclosed in Section 3.11(b) of the Company
Disclosure Schedule, there is no suit, claim, action, proceeding or
investigation pending or, to the Company's knowledge, threatened against the
Company or any of its subsidiaries or any of their respective properties or
assets that (i) if decided adversely to the Company would have, individually or
in the aggregate, a Material Adverse Effect on the Company or (ii) questions the
validity of this Agreement or any action to be taken by the Company in
connection with the consummation of the transactions contemplated hereby or
would otherwise prevent or delay the consummation of the transactions
contemplated by this Agreement. Except as and to the extent disclosed in the
Company SEC Reports filed prior to the date hereof or as set forth in Section
3.11 of the Company Disclosure Schedule, none of the Company or its subsidiaries
is subject to any outstanding order, writ, injunction or decree which has, or
would have, individually or in the aggregate, a Material Adverse Effect on the
Company.

          (c) The Company has prior to the date hereof fully and accurately
disclosed (or caused its outside counsel to disclose) to Parent's General
Counsel, Deputy General Counsel or outside counsel, all facts and information
relating to the Cadence Litigation (as defined in Section 9.11(e)) and the acts
or omissions that are the subject of such Litigation, that in each case could
reasonably be expected to have a bearing on the outcome (or on a reasonable
evaluation of the outcome) of such Litigation, to the extent such information is
known as of the date hereof to any of the persons listed in Section 3.11(c)(i)
to the Company Disclosure Schedule, other than facts and information that,
individually and in the aggregate, would not reasonably be expected to have a
material bearing on the outcome (or on a reasonable evaluation of the outcome)
of the Cadence Litigation. Without limiting the foregoing, the facts and
information not disclosed by the Company to Parent by reason of any joint
defense agreement referred to in Section 3.11(c)(ii) of the Company Disclosure
Schedule or any court-ordered protective order are not inconsistent in any
material respect with the facts and information that have been disclosed by the
Company to Parent.

          3.12. Company Permits; Compliance with Applicable Laws. The Company
and its subsidiaries hold all permits, licenses, variances, exemptions, orders
and approvals of all Governmental Entities necessary for the lawful conduct of
their respective businesses (the "Company Permits"), except for failures to hold
such permits, licenses, variances, exemptions, orders and approvals which would
not have, individually or in the aggregate, a Material Adverse Effect on the
Company. 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,
individually or in the aggregate, a Material Adverse Effect on the Company. The
businesses of the Company and its subsidiaries are not being conducted in
violation of any Law applicable to the Company or its subsidiaries, except for
violations which would not have, individually or in the aggregate, a Material
Adverse Effect on the Company. To the Company's knowledge, no investigation or
review by any Governmental Entity with respect to the Company or its
subsidiaries is pending or threatened, nor, to the Company's knowledge, has any
Governmental Entity indicated an intention to conduct the same.

          3.13. Employee Benefit Plans; ERISA. (a) Neither the Company nor any
of its subsidiaries maintains or contributes to, or has any material obligation
to contribute to, or has or may have any liability, direct or indirect,
contingent or otherwise (including, without limitation, a material liability
arising out of an indemnification, guarantee, hold harmless or similar
agreement) under or with respect to, any employment, consulting, severance,
termination, retirement, profit sharing, bonus, incentive or deferred
compensation, retention or change in control plan, program, arrangement,
agreement or commitment, or bonus, pension, stock option, restricted stock or
other equity-based, profit sharing, savings, life, health, disability, accident,
medical, insurance, vacation, other welfare fringe benefit or other employee
compensation or benefit plan, program, arrangement, agreement, fund or
commitment, including any "employee benefit plan" as defined in Section 3(3) of
the Employee Retirement Income Security Act of 1974, as amended ("ERISA")
providing benefits to any current or former employee, consultant or director of
the Company or any of its subsidiaries or any current or former employee,
consultant or director of any entity with respect to which the Company or its
subsidiaries is a successor (collectively the "Company Benefit Plans"). True and
complete copies of each Company Benefit Plan, including, but not limited to, any
trust instruments and/or insurance contracts, if any, forming a part thereof,
all amendments thereto and the most recent determination letters issued by the
Internal Revenue Service, all government and regulatory approvals received from
any foreign Regulatory Agency, the most recent summary plan descriptions
(including any material modifications), the two most recent annual reports on
Form 5500 (including all exhibits and attachments thereto), the two most recent
actual reports and the two most recent audited financial reports for any funded
Company Benefit Plan have been supplied or made available to Parent. Neither the
Company nor any of its subsidiaries has made any plan or commitment, to create
any additional Company Benefit Plan or modify or change any existing Company
Benefit Plan that would increase the compensation or benefits provided to any
employee or former employee, consultant or director of the Company or any
subsidiary of the Company. Since the Audit Date there has been no material
change, amendment, modification to, or adoption of, any Company Benefit Plan.

          (b) With respect to each Company Benefit Plan: (i) if intended to
qualify under Section 401(a), 401(k) or 403(a) of the Code or under any law or
regulation of any foreign jurisdiction or Regulatory Agency, such plan so
qualifies, its trusts (if any) are exempt from taxation under Section 501(a) of
the Code (or the comparable provisions of any law or regulation of any foreign
jurisdiction or Regulatory Agency) and the consummation of the transaction
contemplated hereby will not adversely affect such qualification or exemption;
(ii) it has been operated and administered in material compliance with its terms
and all applicable laws and regulations (including but not limited to ERISA, the
Code and any relevant foreign laws and regulations); (iii) there are no pending
or threatened claims against, by or on behalf of any Company Benefit Plans or
the assets, fiduciaries or administrators thereof (other than routine claims for
benefits); (iv) no breaches of fiduciary duty under which the Company or a
fiduciary could reasonably be expected to incur a material liability have
occurred; (v) no non-exempt prohibited transaction within the meaning of Section
406 of ERISA or Section 4975 of the Code has occurred; (vi) no Lien imposed
under the Code, ERISA or any foreign law exists; and (vii) all contributions,
premiums and expenses to or in respect of such Company Benefit Plan have been
timely paid in full or, to the extent not yet due, have been adequately accrued

          (c) Neither the Company nor any of its subsidiaries has incurred or
reasonably expects to incur, either directly or indirectly (including as a
result of an indemnification obligation), any material liability under Title I
or IV of ERISA or the penalty, excise tax or joint and several liability
provisions of the Code or any foreign law or regulation relating to employee
benefit plans (including, without limitation, Section 406, 409, 502(i), 502(l),
4069 or 4212(c) of ERISA, or Section 4971, 4975 or 4976 of the Code), or under
any agreement, instrument, statute, rule or legal requirement pursuant to or
under which the Company or any of its subsidiaries or any Company Benefit Plan
has agreed to indemnify or is required to indemnify any person against liability
incurred under, or for a violation or failure to satisfy the requirements of,
any such legal requirement, and to the knowledge of the Company, no event,
transaction or condition has occurred, exists or is expected to occur which
could result in any such material liability to the Company, any of its
subsidiaries or, after the Closing, to Parent.

          (d) The Company and each of its subsidiaries has complied in all
material respects with, and each such Company Benefit Plan conforms in all
material respects in operation and form to, all applicable legal requirements,
including, but not limited to, ERISA, the Code and all applicable U.S. and
non-U.S. securities laws and regulations.

          (e) With respect to each "employee pension benefit plan" (within the
meaning of Section 3(2) of ERISA) as to which either the Company or any
subsidiary of the Company may incur any liability under, or which is subject to,
Section 302 or Title IV of ERISA or Section 412 of the Code:

          (i) no such plan is a "multiemployer plan" (within the meaning of
     Section 3(37) of ERISA) or a "multiple employer plan" (within the meaning
     of Section 413(c) of the Code);

          (ii) no such plan has been terminated so as to result, directly or
     indirectly, in any material liability, contingent or otherwise, of either
     the Company or any subsidiary of the Company under Title IV of ERISA;

          (iii) no complete or partial withdrawal from such plan has been made
     by the Company or any subsidiary of the Company, or by any other person, so
     as to result in any material liability to the Company or any subsidiary of
     the Company, whether such liability is contingent or otherwise;

          (iv) no proceeding has been initiated by any Person (including the
     Pension Benefit Guaranty Corporation (the "PBGC")) to terminate any such
     plan or to appoint a trustee for any such plan;

          (v) no condition or event currently exists or currently is expected to
     occur that could result, directly or indirectly, in any material liability
     of the Company or any subsidiary of the Company under Title IV of ERISA,
     whether to the PBGC or otherwise, on account of the termination of any such
     plan;

          (vi) if any such plan were to be terminated as of the Closing Date or
     if any person were to withdraw from such plan, neither the Company nor any
     subsidiary of the Company would incur, directly or indirectly, any material
     liability under Title IV of ERISA;

          (vii) no "reportable event" (as defined in Section 4043 of ERISA) has
     occurred with respect to any such plan, nor has notice of any such event or
     similar notice to any foreign Regulatory Agency been required to be filed
     for any Company Benefit Plan within the past 12 months nor will any such
     notice be required to be filed as a result of the transactions contemplated
     by this Agreement;

          (viii) no such plan has incurred any "accumulated funding deficiency"
     (as defined in Section 302 of ERISA and section 412 of the Code,
     respectively), whether or not waived, and neither the Company nor any of
     its subsidiaries has provided, or is required to provide, security to any
     Company Benefit Plan pursuant to Section 401(a)(29) of the Code; and

          (ix) the transactions contemplated hereby will not result in any event
     described in section 4062(e) of ERISA.

          (f) With respect to each Company Benefit Plan that is a "welfare plan"
(as defined in Section 3(1) of ERISA), neither the Company nor any subsidiary of
the Company has any material obligations to provide health, life insurance, or
death benefits with respect to current or former employees, consultants or
directors of the Company or any of its subsidiaries beyond their termination of
employment or service, other than as required under Section 4980B of the Code,
and each such Company Benefit Plan may be amended or terminated at any time
without incurring material liability thereunder. There has been no communication
to any employee, consultant or director of the Company or any subsidiary of the
Company that would reasonably be expected to promise or guarantee any such
retiree health or life insurance or other retiree death benefits on a permanent
basis.

          (g) Neither the execution and delivery of this Agreement, nor the
consummation of the transactions contemplated hereby, either alone or in
combination with another event (whether contingent or otherwise) will (i)
entitle any current or former employee, consultant or director of the Company or
any of its subsidiaries or any group of such employees, consultants or directors
to any payment; (ii) increase the amount of compensation or benefits due to any
such employee, consultant or director; (iii) accelerate the vesting, funding or
time of payment of any compensation, equity award or other benefit; (iv) result
in any "parachute payment" under Section 280G of the Code (whether or not such
payment is considered to be reasonable compensation for services rendered); or
(v) cause any compensation to fail to be deductible under Section 162(m) of the
Code, or any other provision of the Code or any similar foreign law or
regulation.

          (h) Under each Company Benefit Plan which is a single-employer plan
and any foreign plan that is a defined benefit plan, as of the last day of the
most recent plan year ended prior to the date hereof, the actuarially determined
present value of all "benefit liabilities", within the meaning of Section
4001(a)(16) of ERISA or, with respect to any foreign plan, as determined under
any equivalent law or practice (in each case as determined on the basis of the
actuarial assumptions contained in Company Benefit Plan's most recent actuarial
valuation), did not exceed the then current value of the assets of such Company
Benefit Plan, and there has been no material adverse change in the financial
condition of such Company Benefit Plan (with respect to either assets or
benefits) since the last day of the most recent plan year.

          (i) Neither the Company nor any of its subsidiaries maintains any
plan, agreement or arrangement, formal or informal, that provides, in the case
of any such formal plan, agreement or arrangement, benefits or, in the case of
any such informal plan, agreement or arrangement, material benefits in the
nature of severance or has outstanding any liabilities with respect to any
severance benefits available under any formal plan, agreement or arrangement or
material severance benefits available under any informal plan, agreement or
arrangement.

          (j) Neither the Company nor any subsidiary of the Company has any
material liability (including a material liability arising out of an
indemnification, guarantee, hold harmless or similar agreement) relating to any
insurance contract held under or purchased to fund a Company Benefit Plan, the
issuer of which is or was insolvent or in reorganization or the payments under
which were suspended.

          (k) Section 3.13(k) of the Company Disclosure Schedule sets forth any
and all indebtedness in excess of fifty thousand U.S. dollars (US$50,000) owed
by any current or former employee, consultant or director to the Company or any
subsidiary of the Company.

          (l) No Company Benefit Plan, nor the Company or any subsidiary of the
Company with respect to any Company Benefit Plan, is under audit or is the
subject of an audit or investigation by the IRS, the U.S. Department of Labor,
the PBGC or any other federal or state governmental agency or any foreign
Regulatory Agency, nor is any such audit or investigation pending or, to the
knowledge of the Company, threatened.

          (m) All liabilities with respect to any current or former employee,
consultant or director of the Company or any subsidiary of the Company or any
affiliate of any member thereof, whether contingent or otherwise, that Parent
will assume by reason of this Agreement or by operation of law are accurately
reflected on the Company's latest audited financial statements.

          (n) Except for the Company Option Plans, the Company Stock Purchase
Plans and as set forth in Section 3.13(n) of the Company Disclosure Schedule,
neither the Company nor any subsidiary of the Company maintains any plan,
program or arrangement or is a party to any contract that provides any material
benefits or provides for material payments to any Person in, based on or
measured by the value of, any equity security of, or interest in, the Company or
any subsidiary of the Company.

          (o) The Company has provided to Parent a true and complete list of
each current or former employee, consultant, officer or director of the Company
or any of its subsidiaries who, as of the date hereof, holds (i) any option to
purchase any shares of Company Common Stock or commitments for future options,
together with the number of shares of Company Common Stock subject to each such

Section 422(b) of the Code, and the expiration date of each such option, (ii)
any shares of Company Common Stock that are unvested or subject to a repurchase
option, risk of forfeiture or other condition providing that such shares may be

Stock (or any other unit of Company equity), together with the number of shares
of Company Common Stock (or any other unity of Company equity) subject to such
right.

          (p) Except as set forth in Section 3.13(p) of the Company Disclosure
Schedule, there are no material liabilities, whether contingent or absolute, of
the Company or any of its subsidiaries relating to workers' compensation
benefits that are not fully insured against by a bona fide third-party insurance
carrier.

          (q) With respect to each Company Benefit Plan and with respect to each
state workers' compensation arrangement, that is funded wholly or partially
through an insurance policy or public or private fund, all premiums required to
have been paid to date under such insurance policy or fund have been paid, all
premiums required to be paid under the insurance policy or fund through the
Closing Date will have been paid on or before the Closing Date and, as of the

regarding the terms and conditions of employment of employees, former employees
or prospective employees or other labor related matters, including laws, rules,

subsidiary or any other entity other than loans to subsidiaries in the ordinary
course of business.

Issuance and no corporate or company proceedings on the part of Parent or Merger

time they are available, such quarterly and annual financial statements as are
prepared for Parent's SEC filings, which shall be in accordance with the books
and records of Parent.

          (c) Parent will hold and will cause its authorized representatives to
hold in confidence all documents and information concerning the Company and its
subsidiaries furnished to Parent in connection with the transactions
contemplated by this Agreement pursuant to the terms of that certain
Confidentiality Agreement entered into between the Company and Parent dated
September 9, 2001 (the "Confidentiality Agreement"). The Company will hold and
will cause its authorized representatives to hold in confidence all documents
and information concerning Parent and its subsidiaries furnished to the Company
in connection with the transactions contemplated by this Agreements pursuant to
the terms of that certain Confidentiality Agreement entered into between the
Company and Parent dated September 24, 2001 (the "Parent Confidentiality
Agreement").

          (d) Any documents or information disclosed by the Company or any of
its subsidiaries to Parent pursuant to Section 3.18(a), Section 5.1 or clause
(a) or (b) of this Section 5.3 shall be used by Parent solely for the evaluation
of, and/or transitional planning in connection with, the transactions
contemplated hereby and shall, for the avoidance of doubt, be subject to clause
(c) of this Section 5.3; provided that the restrictions set forth in this clause
(d) shall not apply to the disclosure of any document or information that is
exempted from the confidentiality restrictions set forth in the Confidentiality
Agreement pursuant to the terms thereof.

          5.4. Company Litigation. The Company will (i) at such intervals as are
reasonably specified by Parent provide Parent with information as to the status
of all existing or new litigations in which the Company or any Company
subsidiary is a party and (ii) promptly notify Parent of, and consult with
Parent as to, any material developments concerning any such litigation.

          5.5. Dispositions. Prior to the Effective Time, Parent and the Company
shall take all such steps as may be required to cause any dispositions of
Company Common Stock (including derivative securities with respect to Company
Common Stock) resulting from the transactions contemplated by this Agreement by
each individual who is subject to the reporting requirements of Section 16(a) of
the Exchange Act with respect to the Company, to be exempt under Rule 16b-3
promulgated under the Exchange Act, such steps to be taken in accordance with
the No-Action Letter dated January 12, 1999, issued by the SEC to Skadden, Arps,
Slate, Meagher & Flom LLP.

          5.6. Maingate. As promptly as possible, and in any event not later
than December 31, 2001, the Company shall (i) repurchase the Maingate shares it
sold in January 2001 for not more than the one million U.S. dollars
(U$1,000,000) it received at that time, and (ii) repurchase all other Maingate
shares (and all options or other equity or potential equity rights) it does not
own for a cash amount of not more than the Maingate Purchase Price (as defined
below). Between the date hereof and the date of such transactions, Maingate
shall be operated only in the ordinary course of business in accordance with
past practice. Without limiting the foregoing, during such period Maingate shall
not declare or pay any dividends, or repurchase any outstanding shares (or
options or other equity or potential equity rights) or enter into any
transactions with any affiliate or shareholder thereof (other than transactions
in the ordinary course of business consistent with past practice with the
Company or its subsidiaries). The "Maingate Purchase Price" shall be the lesser
of (i) the value determined by multiplying the midpoint of the high and low
values of the range established by the independent appraiser that has been
retained for such purpose by the percentage of the outstanding Maingate shares
owned in the aggregate by the shareholders other than the Company (after giving
effect to the repurchase referred to in clause (i) above), and (ii) a formula
price equal to the amount determined pursuant to the following formula:

                          formula price = US$13,000,000 minus A minus B.
                                                        -----   -----

For purposes of this formula, A shall equal fifteen million U.S. dollars
(US$15,000,000) minus the amount of cash on the balance sheet of Maingate at the
time of closing of the transactions contemplated by this Section 5.6.
Notwithstanding the previous sentence, if A is a negative amount, it shall not
be subtracted under the previous sentence in determining the formula price. For
purpose of the formula, B shall equal one million three hundred and fifty
thousand U.S. dollars (US$1,350,000) minus (x minus y) where x is the total
amount of assets on the balance sheet of Maingate at the time of closing of such
transactions other than cash, and y is the total amount of liabilities on the
balance sheet at the time of closing of such transactions other than accounts
payable-trade owing to the Company. Notwithstanding the previous sentence, B
shall not be subtracted in determining the formula price if B is a negative
number or if A plus B is a negative number.

                                   ARTICLE VI

                              ADDITIONAL AGREEMENTS

          6.1. Preparation of S-4 and the Proxy Statement. Each of Parent and
the Company shall cooperate and as promptly as practicable jointly prepare and
Parent shall file with the SEC as promptly as practicable the S-4 under the
Securities Act with respect to the Share Issuance. A portion of the S-4 shall
serve as a prospectus with respect to the Share Issuance and as the Proxy
Statement in connection with the vote of the stockholders of the Company with
respect to the Merger and the vote of the stockholders of Parent with respect to
the Share Issuance. Parent will cause the S-4 to comply as to form in all
material respects with the applicable provisions of the Securities Act and the
rules and regulations thereunder and the Company will cause the Proxy Statement,
to the extent it relates to such Party, to comply as to form in all material
respects with the applicable provisions of the Exchange Act and the rules and
regulations thereunder. Parent and the Company will, and will cause their
respective accountants and lawyers to, use all reasonable best efforts to have
or cause the S-4 declared effective as promptly as practicable after filing with
the SEC, including, without limitation, causing their accountants to deliver
necessary or required instruments such as opinions, consents and certificates,
and will take any other action required or necessary to be taken under federal
or state securities Laws or otherwise in connection with the registration
process (other than qualifying to do business in any jurisdiction which it is
not now so qualified or to file a general consent to service of process in any
jurisdiction). Each of the Company and Parent shall, as promptly as practicable
after the receipt thereof, provide to the other Party copies of any written
comments and advise the other Party of any oral comments, with respect to the
Proxy Statement or the S-4 received from the staff of the SEC. Each of the
Company and Parent will provide the other Party with a reasonable opportunity to
review and comment on any amendment or supplement to the Proxy Statement prior
to filing with the SEC and will provide the other Party with a copy of all such
filings with the SEC. Each of Parent and the Company will use its reasonable
best efforts to cause the Proxy Statement to be mailed to its stockholders at
the earliest practicable date.

          6.2. Meetings. (a) The Company shall take all lawful action to (i)
cause a special meeting of its stockholders (the "Company Stockholder Meeting")
to be duly called and held as soon as practicable after the date of this
Agreement for the purpose of voting on the approval and adoption of the
"agreement of merger" (within the meaning of Section 251 of the DGCL) contained
in this Agreement, and the Merger, and (ii) solicit proxies from its
stockholders with respect to such vote, which solicitation, unless the Company
Board withdraws its recommendation of such approval and adoption in accordance
with Section 6.4(b), shall be to obtain the Required Company Vote for such
approval and adoption. Except as permitted by Section 6.4(b), the Company Board
shall recommend approval and adoption of the "agreement of merger" contained in
this Agreement and the Merger by the Company's stockholders and, the Company
Board shall not withdraw, amend or modify in a manner adverse to Parent such
recommendation (or announce publicly its intention to do so). The Company shall
submit this Agreement to its stockholders at the Company Stockholder Meeting
even if the Company Board shall have withdrawn, amended or modified in a manner
adverse to Parent such recommendation or announced publicly its intention to do
so as permitted by Section 6.4(b).

          (b) Parent shall take all lawful action to (i) cause a special meeting
of its stockholders (the "Parent Stockholder Meeting") to be duly called and
held as soon as practicable after the date of this Agreement for the purpose of
voting on the approval of the Share Issuance and (ii) solicit proxies from its
stockholders with respect to such vote, which solicitation, unless the Parent
Board withdraws its recommendation of such approval in accordance herewith,
shall be to obtain the Required Parent Vote. The Parent Board shall recommend
approval of the Share Issuance by Parent's stockholders and shall not withdraw,
amend or modify, in a manner adverse to the Company, its recommendation that
stockholders vote in favor of the Share Issuance (or publicly announce its
intention to do so); provided that nothing herein shall require Parent Board to
make (or prevent Parent Board from withdrawing, amending or modifying in a
manner adverse to the Company) any such recommendation in the event that (1)
Parent Board after consultation with and based upon the advice of independent
legal counsel, determines in good faith that to make (or to refrain from
withdrawing, amending or modifying in a manner adverse to the Company) such
recommendation, would cause Parent Board to fail to be in compliance with its
fiduciary duties to Parent's stockholders under any applicable Law and (2)
Parent shall have delivered to Company a prior written notice advising Company
that it intends to take such action and describing its reasons for taking such
action (such notice to be delivered not less than three Business Days prior to
the time such action is taken). Parent shall hold the Parent Stockholder Meeting
for the purpose of voting on the approval of the Share Issuance even if the
Parent Board shall not have made, or shall have withdrawn, amended or modified
in a manner adverse to Parent, such recommendation or announced publicly its
intention to do so as permitted hereby.

          6.3. Commercially Reasonable Best Efforts. (a) Subject to the terms
and conditions of this Agreement, each Party will use its commercially
reasonable best efforts to take, or cause to be taken, all actions and to do, or
cause to be done, all things necessary, proper or advisable under applicable
Laws promptly to consummate the Merger and the other transactions contemplated
by this Agreement. In furtherance and not in limitation of the foregoing, each
Party hereto agrees to make an appropriate filing of a Notification and Report
Form pursuant to the HSR Act with respect to the transactions contemplated
hereby as promptly as practicable and to supply as promptly as practicable any
additional information and documentary material that may be requested pursuant
to the HSR Act and use its commercially reasonable best efforts to take, or
cause to be taken, all other actions consistent with this Section 6.3 necessary
to cause the expiration or termination of the applicable waiting periods under
the HSR Act as soon as practicable.

          (b) Each of Parent and the Company shall, in connection with the
efforts referenced in Section 6.3(a) to obtain all requisite approvals and
authorizations for the transactions contemplated by this Agreement under the HSR
Act or any other Antitrust Law, (i) use its commercially reasonable best efforts
to cooperate in all respects with each other in connection with any filing or
submission and in connection with any investigation or other inquiry, including
any proceeding initiated by a private party; and (ii) keep the other Party
informed in all material respects of any material communication received by such
Party from, or given by such Party to, the Federal Trade Commission (the "FTC"),
the Antitrust Division of the Department of Justice (the "DOJ") or any other
Governmental Entity and of any material communication received or given in
connection with any proceeding by a private party, in each case regarding any of
the transactions contemplated hereby. For purposes of this Agreement, "Antitrust
Law" means the Sherman Act, as amended, the Clayton Act, as amended, the HSR
Act, the Federal Trade Commission Act, as amended, and all other Laws (including
other national merger control laws or foreign investment regulations) that are
designed or intended to prohibit, restrict or regulate actions having the
purpose or effect of monopolization or restraint of trade or lessening of
competition through merger or acquisition.

          (c) In furtherance and not in limitation of the covenants of the
parties contained in Sections 6.3(a) and 6.3 (b), each of Parent and the Company
shall use its commercially reasonable best efforts to resolve such objections if
any, as may be asserted a Governmental Entity or other person with respect to
the transactions contemplated hereby under any Antitrust Law. In connection with
the foregoing, if any administrative or judicial action or proceeding, including
any proceeding by a private party, is instituted (or threatened to be
instituted) challenging any transaction contemplated by this Agreement as
violative of any Antitrust Law, each of Parent and the Company shall cooperate
in all respects with each other and use its respective commercially reasonable
best efforts to contest and resist any such action or proceeding and to have
vacated, lifted, reversed or overturned any decree, judgment, injunction or
other order, whether temporary, preliminary or permanent, that is in effect and
that prohibits, prevents or restricts consummation of the transactions
contemplated by this Agreement. Notwithstanding the foregoing or any other
provision of this Agreement, nothing in this Section 6.3 shall (i) limit a
Party's right to terminate this Agreement pursuant to Section 8.2 (a) or (d) so
long as such Party has theretofore complied in all material respects with its
obligations under this Section 6.3 or (ii) require Parent to (x) enter into any
"hold-separate" agreement or other agreement with respect to the disposition of
any assets or businesses of the Parent or any of its subsidiaries or the Company
or any of its subsidiaries in order to obtain clearance from the FTC or the DOJ
or any other antitrust or competition authorities to proceed with the
consummation of the transactions contemplated hereby; or (y) consummate the
transactions contemplated hereby in the event that any consent, approval,
authorization or non-objection of any Governmental Entity obtained or sought to
be obtained in connection with this Agreement is conditioned upon the imposition
of any other significant restrictions upon, or the making of any material
accommodation (financial or otherwise) in respect of the transactions
contemplated hereby or the conduct of the business of the Surviving Company or
the Parent (including any agreement not to compete in any geographic area or
line of business or any agreement to license technology to third parties) or
results, or would result in, the abrogation or diminishment of any authority or
license granted by any Governmental Entity.

          (d) The Company shall use its reasonable best efforts in consultation
with Parent to obtain any consents of third parties with respect to any Company
Agreements that may be necessary or appropriate for the purposes of the
transactions contemplated hereby.

          6.4. Acquisition Proposals. (a) The Company agrees that (1) it will
not (and it will cause its subsidiaries and each officer, director or employee
of the Company or any of its subsidiaries not to) directly or indirectly: (i)
solicit, initiate or encourage the submission of any Acquisition Proposal (as
defined in Section 9.11 herein), (ii) participate in any discussions or
negotiations regarding, or furnish to any person any non-public information with
respect to the Company or any of its subsidiaries in connection with, or take
any other action to facilitate, any Acquisition Proposal or any inquiries or the
making of any proposal that constitutes, or may reasonably be expected to lead
to, any Acquisition Proposal or (iii) enter into any agreement with respect to
an Acquisition Proposal and (2) it will not authorize or permit any investment
banker, attorney or accountant, or other advisor or representative of, the
Company or any of its subsidiaries to take any of the actions referred to in
clauses (1)(i), (ii) or (iii); provided, however, that nothing contained in this
Section 6.4(a) shall prohibit the Company Board from furnishing information to,
or entering into discussions or negotiations with, any person that makes an
unsolicited bona fide written Acquisition Proposal if, and only to the extent
that (A) the Company Board, after consultation with and based upon the advice of
independent legal counsel, reasonably determines in good faith that such action
is necessary for the Company Board to comply with its fiduciary duties to the
Company's stockholders under applicable Law, (B) the Company Board reasonably
determines in good faith that such Acquisition Proposal, if accepted, is
reasonably likely to be consummated taking into account all legal, financial,
regulatory and other aspects of the proposal and the person making the proposal,
and believes in good faith, after consultation with an independent, nationally
recognized financial advisor, that such Acquisition Proposal would, if
consummated, result in a transaction materially more favorable to the Company's
stockholders from a financial point of view than the Merger (any such materially
more favorable Acquisition Proposal being referred to herein as a "Superior
Proposal"), and (C) prior to taking such action, the Company (x) provides three
Business Day prior written notice to Parent to the effect that it is proposing
to take such action and (y) receives from such person an executed
confidentiality agreement in reasonably customary form and in any event
containing terms at least as stringent as those contained in the Confidentiality
Agreement. The Company shall notify Parent of any Acquisition Proposal or
request for nonpublic information by any person who is making, or who has
indicated that it is considering making, an Acquisition Proposal (including,
without limitation, all material terms and conditions thereof and the identity
of the person making it) as promptly as practicable (but in no case later than
24 hours) after its receipt thereof, and shall provide Parent with a copy of any
written Acquisition Proposal or amendments or supplements thereto, and shall
thereafter inform Parent on a current basis of the status of any inquiries,
discussions or negotiations with such a third party, and any material changes to
the terms and conditions of such Acquisition Proposal, and shall promptly give
Parent a copy of any information delivered to such person which has not
previously been made available to Parent. Immediately after the execution and
delivery of this Agreement, the Company will, and will cause its subsidiaries
and affiliates, and their respective officers, directors, employees, investment
bankers, attorneys, accountants and other agents to, cease and terminate any
existing activities, discussions or negotiations with any parties conducted
heretofore with respect to any possible Acquisition Proposal and shall notify
each Party that it, or any officer, director, investment advisor, financial
advisor, attorney or other representative retained by it, has had discussions
with during the 90 days prior to the date of this Agreement that the Company
Board no longer seeks or requests the making of any Acquisition Proposal, and
withdraws any consent theretofore given to the making of an Acquisition
Proposal.

          (b) The Company Board will not withdraw or modify, or propose to
withdraw or modify, in a manner adverse to Parent, its recommendation that
stockholders vote in favor of the Merger unless (i) the Company has fully
complied with the terms of Section 6.4(a), (ii) the Company Board after
consultation with and based upon the advice of independent legal counsel,
determines in good faith that such action is necessary for the Company Board to
comply with its fiduciary duties to the Company's stockholders under applicable
Law and (iii) the Company shall have delivered to Parent a prior written notice
advising Parent that it intends to take such action and describing its reasons
for taking such action (such notice to be delivered not less than three Business
Days prior to the time such action is taken). Nothing contained in this Section
6.4(b) shall prohibit the Company from taking and disclosing to its stockholders
a position contemplated by Rule 14e-2(a) promulgated under the Exchange Act.

          (c) Nothing in this Section 6.4 shall (i) permit the Company to
terminate this Agreement (except as provided in Article VIII hereof) or (ii)
affect any other obligations of the Company under this Agreement.

          6.5. Public Announcements. Each of Parent and the Company will consult
with one another before issuing any press release or otherwise making any public
statements with respect to the transactions contemplated by this Agreement,
including, without limitation, the Merger, and shall not issue any such press
release or make any such public statement prior to such consultation, except as
may be required by applicable Law or by obligations pursuant to any listing
agreement with the NASD, as determined by Parent or the Company, as the case may
be.

          6.6. Indemnification; Directors' and Officers' Insurance. (a) The
Parent agrees that all rights now existing to exculpation, release, and
indemnification for acts or omissions occurring prior to the Effective Time now
existing in favor of the current or former directors or officers (the
"Indemnified Parties") of the Company as provided in its certificate of
incorporation or bylaws or in any agreement listed in Section 6.6 of the Company
Disclosure Schedule shall survive the Merger and shall continue in full force
and effect indefinitely in accordance with their terms following the Effective
Time.

          (b) For a period of six years after the Effective Time, Parent shall
cause to be maintained in effect the policies of directors' and officers'
liability insurance maintained by the Company for the benefit of those persons
who are covered by such policies at the Effective Time (or Parent may substitute
therefor policies of at least the same coverage with respect to matters
occurring prior to the Effective Time), to the extent that such liability
insurance can be maintained at a cost to Parent not greater than 200 percent of
the annual premium for the current Company directors' and officers' liability
insurance as set forth in Section 6.6 of the Company Disclosure Schedule;
provided, that if such insurance cannot be so maintained or obtained at such
costs, Parent shall maintain or obtain as much of such insurance as can be so
maintained or obtained at a cost equal to 200 percent of such annual premiums of
the Company for such insurance.

          6.7. Notification of Certain Matters. The Company shall, upon
obtaining knowledge of any of the following, give prompt notice to Parent, and
Parent shall, upon obtaining knowledge of any of the following, give prompt
notice to the Company: (i) the occurrence or nonoccurrence of any event the
occurrence or nonoccurrence of which would reasonably be likely to cause any
representation or warranty of such Party contained in this Agreement, which is
qualified as to materiality, to be untrue or inaccurate, or any representation
or warranty of such Party not so qualified, to be untrue or inaccurate in any
material respect, at or prior to the Effective Time; (ii) any material failure
of the Company or Parent, as the case may be, to comply with or satisfy any
covenant, condition or agreement to be complied with or satisfied by it
hereunder; (iii) the occurrence or non-occurrence of any event the occurrence or
non-occurrence of which would reasonably be likely to cause any condition to the
obligations of any Party to effect the transactions contemplated hereby not to
be satisfied; (iv) any notice of, or other communication relating to, a default
or event which, with notice or lapse of time or both, would become a default,
received by it or any of its subsidiaries subsequent to the date of this
Agreement and prior to the Effective Time, under any contract or agreement
material to the financial condition, properties, businesses, results of
operations or prospects of it and its subsidiaries taken as a whole to which it
or any of its subsidiaries is a party or is subject; (v) any material notice or
other material communication from any Governmental Entity in connection with the
Merger; (vi) any actions, suits, claims, investigations or other proceedings (or
communications indicating that the same may be contemplated) commenced or
threatened against the Company or any of its subsidiaries or Parent or any of
its subsidiaries, as applicable, which, if pending on the date of this
Agreement, would have been required to have been disclosed pursuant to Section
3.11 of the Company Disclosure Schedule, or Section 4.13 of the Parent
Disclosure Schedule, or which relate to the consummation of the Merger; (vii)
any notice or other communication from any third party alleging that the consent
of such third party is or may be required in connection with the transactions
contemplated by this Agreement; or (viii) any event or occurrence that is, or
would reasonably be likely to be, a Material Adverse Effect with respect to it;
provided, however, that the delivery of any notice pursuant to this Section 6.7
shall not cure such breach or non-compliance or limit or otherwise affect the
remedies available hereunder to the Party receiving such notice.

          6.8. Certification. The Company, Parent and Merger Sub shall execute
and deliver to O'Melveny & Myers LLP, counsel to the Company, and to Cleary,
Gottlieb, Steen & Hamilton, counsel to Parent and Merger Sub, certificates
substantially in the forms attached hereto as Exhibit B (in the case of the
Company) and Exhibit C (in the case of Parent and Merger Sub) at such time or
times as reasonably requested by such law firms in connection with their
respective deliveries of tax opinions with respect to the transactions
contemplated hereby. Prior to the Effective Time, none of the Company, Parent or
Merger Sub shall take or cause to be taken any action which would cause to be
untrue (or fail to take or cause not to be taken any action which would cause to
be untrue) any of the representations in such certificates.

          6.9. Employee Matters. On or as soon as practicable following the
Effective Time, those employees of the Company and its subsidiaries who will
continue employment with Parent or the Surviving Company ("Continuing Employees"
) shall be eligible to participate in those benefit plans and programs
maintained by Parent for similarly situated employees of Parent generally (or in
substantially similar programs), but explicitly excluding individual plans,
programs, arrangements or agreements on the same terms applicable to similarly
situated employees of Parent. Each Continuing Employee shall be given credit,
for purposes of eligibility to participate and vesting (but not for benefit
accrual purposes), for his or her period of service with the Company or any of
its subsidiaries credited under a similar plan prior to the Effective Time,
subject to applicable break in service rules. Each such employee shall, with
respect to any Parent plans or programs which have co-payment, deductible or
other co-insurance features, receive credit for any amounts such individual has
paid to date in the plan year of the Effective Time under comparable plans or
programs maintained by the Company or any of its subsidiaries prior to the
Effective Time. Each Continuing Employee and eligible dependent who, at the
Effective Time, was participating in an employee group health plan maintained by
the Company or any of its subsidiaries shall not be excluded from Parent's
employee group health plan or limited in coverage thereunder by reason of any
waiting period restriction or pre-existing condition limitation that would not
have excluded such claim under the applicable Company Plan.

          6.10. Affiliate Letters. Section 6.10 of the Company Disclosure
Schedule sets forth a list of all persons who are, and all persons who to the
Company's knowledge will be at the Closing Date, "affiliates" of the Company for
purposes of Rule 145 under the Securities Act. The Company will cause such list
to be updated promptly through the Closing Date. Not later than the date of the
initial mailing of the Proxy Statement, the Company shall use its best efforts
to cause its "affiliates" to deliver to Parent a written agreement substantially
in the form attached as Exhibit A.

          6.11. SEC Filings.


          (a) The Company shall furnish to the Parent copies of all reports,
proxy statements and prospectuses of the type referred to in Section 3.4 which
it files with the SEC on or after the date hereof, and the Company represents
and warrants that as of the respective dates thereof, such reports will not
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading. The
audited consolidated financial statements and the unaudited consolidated interim
financial statements included in such reports (including any related notes and
schedules) will fairly present the financial position of the Company and its
consolidated subsidiaries as of the dates thereof and the results of operations
and cash flows or other information included therein for the periods or as of
the date then ended (subject, in the case of the interim financial statements,
to normal, recurring year-end adjustments which will not be material in amount),
in each case in accordance with past practice and GAAP consistently applied
during the periods involved (except as otherwise disclosed in the notes
thereto.) The Company shall additionally furnish to Parent all correspondence
that the Company or its counsel or accountants furnish to or receive from the
SEC after the date hereof and shall notify Parent of, and consult with Parent as
to, all other communications between the Company or its counsel or accountants
and the SEC.

          (b) The Parent shall furnish to the Company copies of all reports,
proxy statements and prospectuses of the type referred to in Section 4.4 which
it files with the SEC on or after the date hereof, and the Parent represents and
warrants that as of the respective dates thereof, such reports will not contain
any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading. The
audited consolidated financial statements and the unaudited consolidated interim
financial statements included in such reports (including any related notes and
schedules) will fairly present the financial position of the Parent and its
consolidated subsidiaries as of the dates thereof and the results of operations
and cash flows or other information included therein for the periods or as of
the date then ended (subject, in the case of the interim financial statements,
to normal, recurring year-end adjustments which will not be material in amount),
in each case in accordance with past practice and GAAP consistently applied
during the periods involved (except as otherwise disclosed in the notes
thereto).

          6.12. Fees and Expenses. Subject to Section 6.15 and Section 8.5,
whether or not the Merger is consummated, all Expenses incurred in connection
with this Agreement, and the transactions contemplated hereby shall be paid by
the Party incurring such Expenses, except Expenses (including filing fees)
incurred in connection with the filing, printing and mailing of the Proxy
Statement and the S-4 shall be shared equally by the Company and Parent. As used
in this Agreement, "Expenses" includes all out-of-pocket expenses (including,
without limitation, all fees and expenses of counsel, accountants, investment
bankers, experts and consultants to a Party hereto and its affiliates) incurred
by a Party or on its behalf in connection with, or related to, the
authorization, preparation, negotiation, execution and performance of this
Agreement and the transactions contemplated hereby, including the preparation,
filing, printing and mailing of the Proxy Statement and the S-4 and the
solicitation of stockholder approvals and all other matters related to the
transactions contemplated hereby.

          6.13. Listing of Stock. Parent shall use its best efforts to cause the
shares of Parent Common Stock to be issued in connection with the Merger to be
approved for listing on the NASDAQ National Market System on or prior to the
Closing Date, subject to official notice of issuance.

          6.14. Takeover Statutes. If any Takeover Statute is or may become
applicable to the Merger, each of Parent and Company shall take such actions as
are necessary so that the transactions contemplated by this Agreement and the
Voting Agreement may be consummated as promptly as practicable on the terms
contemplated hereby and otherwise act to eliminate or minimize the effects of
any Takeover Statute on the Merger.

          6.15. Direct Payment of Expenses. If the Transaction Costs (defined
below) incurred by the Company in connection with the Merger and the other
transactions contemplated by this Agreement exceed 10 percent of the net equity
value of the Company immediately prior to the Effective Time, then Parent shall
directly pay Expenses of the Company that are solely and directly related to the
Merger so that the Transaction Costs reduced by the amount of the Company
Expenses paid by Parent are less than 10 percent of the net equity value of the
Company at the Effective Time. For purposes of this Agreement, the term
"Transaction Costs" " means all costs, payments, benefits and expenses that are
triggered by, or incurred in connection with, the Merger or the consummation of
the other transactions contemplated hereby (including without limitation, all
Expenses and any change of control and severance payments).

Section 8.5(b)(ii)(y)(B) or upon the entering into of a Cadence Settlement
Proposal as referred to in Section 8.5(b)(iii)(y) in the case of a termination
by the Company referred to in Section 8.5(b)(ii)(y)(2) or Section
8.5(b)(iii)(y)(2).

          (c) The Company acknowledges that the agreements contained in Section
8.5(b) are an integral part of the transactions contemplated by this Agreement,
and that, without these agreements, Parent would not have entered into this
Agreement; accordingly, if the Company fails to promptly pay the amount due
pursuant to Section 8.5(b), and, in order to obtain such payment, Parent
commences a suit which results in a judgment against the Company for the fee set
forth in this Section 8.5, the Company shall pay to Parent its costs and
expenses (including attorneys' fees) in connection with such suit, together with
interest from the date of termination of this Agreement on the amounts owed at
the prime rate of Citibank N.A. in effect from time to time during such period
plus 2 percent.

          8.6. Amendment. This Agreement may be amended by action taken by the
Company, Parent and Merger Sub at any time before or after approval of the
Merger by the Required Company Vote and the approval of the Share Issuance by
the Required Parent Vote but, after any such approval, no amendment shall be
made which requires the approval of such stockholders under applicable Law
without such approval. This Agreement may not be amended except by an instrument
in writing signed on behalf of the Parties hereto.

          8.7. Extension; Waiver. At any time prior to the Effective Time, each
Party hereto (for these purposes, Parent and Merger Sub shall together be deemed
one Party and the Company shall be deemed the other Party) may (i) extend the
time for the performance of any of the obligations or other acts of the other
Party, (ii) waive any inaccuracies in the representations and warranties of the
other Party contained herein or in any document, certificate or writing
delivered pursuant hereto, or (iii) waive compliance by the other Party with any
of the agreements or conditions contained herein. Any agreement on the part of
either Party hereto to any such extension or waiver shall be valid only if set
forth in an instrument in writing signed on behalf of such Party. The failure of
either Party hereto to assert any of its rights hereunder shall not constitute a
waiver of such rights.

          8.8. Breaches Relating to Litigation. Notwithstanding any other
provision in this Agreement to the contrary, the Company shall not be deemed to
be in breach of any representation or warranty contained herein, except for any
representation or warranty contained in Section 3.11(c), to the extent that such
breach results from the pendency of, or developments with respect to, the
Cadence Litigation or is based on the acts or omissions that are the subject of
such Litigation; provided, however, that this Section 8.8 shall not apply in the
event that the Company has breached any representation or warranty in Section
3.11(c).

                                   ARTICLE IX

                                  MISCELLANEOUS

          9.1. Nonsurvival of Representations and Warranties. None of the
representations, warranties, covenants and agreements in this Agreement or in
any exhibit, schedule or instrument delivered pursuant to this Agreement shall
survive beyond the Effective Time. This Section 9.1 shall not limit any covenant
or agreement of the parties which by its terms contemplates performance after
the Effective Time.

          9.2. Entire Agreement; Assignment. (a) This Agreement (including the
schedules) constitutes the entire agreement between the parties hereto with
respect to the subject matter hereof and supersedes all other prior agreements
and understandings, both written and oral, between the parties with respect to
the subject matter hereof, other than the Confidentiality Agreement, the Parent
Confidentiality Agreement and the information sharing agreement between Parent
and the Company with respect to the Cadence Litigation.

          (b) Neither this Agreement nor any of the rights, interests or
obligations hereunder shall be assigned by operation of Law (including, but not
limited to, by merger or consolidation) or otherwise; provided, however, that
Merger Sub may assign, in its sole discretion, any or all of its rights,
interests and obligations under this Agreement to any direct wholly owned
subsidiary of Parent, but no such assignment shall relieve Parent or Merger Sub
of its obligations hereunder if such assignee does not perform such obligations.
Any assignment in violation of the preceding sentence shall be void. Subject to
the preceding sentence, this Agreement will be binding upon, inure to the
benefit of, and be enforceable by, the parties and their respective successors
and assigns.

disfavoring any Party by virtue of the authorship of any provisions of this
Agreement.

Synopsys, Inc.

Mountain View, CA  94043

Dear Sir/Madam:

Reference is made to the provisions of the Agreement and Plan of Merger, dated
as of December 3, 2001 (together with any amendments thereto, the "Merger
Agreement"), among Avant! Corporation, a Delaware corporation (the "Company"),
Synopsys, Inc., a Delaware corporation ("Parent"), and Maple Forest Acquisition
L.L.C., a Delaware limited liability company and a direct wholly owned
subsidiary of Parent ("Merger Sub"), pursuant to which the Company will be
merged with and into Merger Sub, with Merger Sub continuing as the Surviving
Company (the "Merger"). This letter constitutes the undertakings of the
undersigned contemplated by the Merger Agreement, as is being furnished pursuant
to Section 6.10 thereto.

I understand that I may be deemed to be an "affiliate" of the Company, as such
term is defined for purposes of paragraphs (c) and (d) of Rule 145 ("Rule 145")
promulgated under the Securities Act of 1933, as amended (the "Securities Act").
Execution of this letter shall not be construed as an admission of "affiliate"
status nor as a waiver of any rights that I may have to object to any claim that
I am an "affiliate" on or after the date of this letter.

If in fact I were to be deemed an "affiliate" of the Company under paragraphs
(c) and (d) of Rule 145, my ability to sell, transfer or otherwise dispose of
any shares of the common stock, par value $0.01 per share, of Parent (the
"Parent Shares") received by me in exchange for any shares of common stock, par
value $0.0001 per share, of the Company (the "Company Shares") pursuant to the
Merger may be restricted.

I hereby represent, warrant and covenant to Parent that:

         I will not sell, pledge, transfer or otherwise dispose of any of the
Parent Shares except (i) pursuant to an effective registration statement under
the Securities Act, or (ii) as permitted by, and in accordance with, Rule 145 or
another applicable exemption under the Securities Act and the rules and
regulations promulgated thereunder.

I hereby acknowledge that Parent is under no obligation to register the sale,
transfer, pledge or other disposition of the Parent Shares or to take any other
action necessary for the purpose of making an exemption from registration
available.

I understand that Parent will issue stop transfer instructions to its transfer
agents with respect to the Parent Shares and that a restrictive legend will be
placed on certificates delivered to me evidencing the Parent Shares in
substantially the following form:

         "This certificate and the shares represented hereby have been issued
         pursuant to a transaction governed by Rule 145 ("Rule 145") promulgated
         under the Securities Act of 1933, as amended (the "Securities Act"),
         and may not be sold or otherwise disposed of unless registered under
         the Securities Act pursuant to a registration statement in effect at
         the time or unless the proposed sale or disposition can be made in
         compliance with Rule 145 or without registration in reliance on another
         exemption therefrom. Reference is made to that certain letter
         agreement, dated [Date], between the holder of this certificate and the
         issuer of this security (a copy of which is on file in the principal
         office of such issuer) which contains further restrictions on the
         transferability of the shares represented hereby."

The term Parent Shares as used in this letter shall mean and include not only
the common stock of Parent as presently constituted, but also any other stock
which may be issued in exchange for, in lieu of, or in addition to, all or any
part of such Parent Shares.

I agree that, from time to time, at Parent's reasonable request and without
further consideration, I shall execute and deliver such additional documents and
shall use my reasonable best efforts to take all such further lawful action as
may be reasonably necessary or desirable to consummate and make effective, in
the most expeditious manner practicable, the transactions contemplated by the
Merger Agreement.

I understand the requirements of this letter and the limitations imposed upon
the transfer, sale or other disposition of the Company Shares and the Parent
Shares.

                                                     Very truly yours,

                                                     Name:





                                                                       Exhibit B

Cleary, Gottlieb, Steen & Hamilton

New York, NY  10006

O'Melveny and Myers LLP
400 South Hope Street
Los Angeles, CA 90071

Ladies and Gentlemen:

          We refer to the Agreement and Plan of Merger dated as of December 3,
2001 (the "Agreement") by and among Synopsys, Inc. ("Parent"), a Delaware
corporation, Maple Forest Acquisition L.L.C. ("Merger Sub"), a Delaware limited
liability company that is wholly-owned by Parent and a company that is and will
be treated as a disregarded entity for U.S. federal income tax purposes and
Avant! Corporation (the "Company"), a Delaware corporation, which provides,
among other things, for the merger (the "Merger") of the Company with and into
Merger Sub, on the terms and conditions set forth therein, the time at which the
Merger becomes effective being hereafter referred to as the "Effective Time."
The Agreement requires that as a condition to the consummation of the Merger,
Cleary, Gottlieb, Steen & Hamilton, counsel to the Parent and O'Melveny and
Myers LLP, counsel to the Company, render opinions regarding certain United
States federal income tax consequences of the Merger. Capitalized terms not
defined herein have the meanings specified in the Agreement. For purposes of
this letter, it is assumed that Merger Sub will be classified as a disregarded
entity within the meaning of Treasury regulation section 301.7701-3(b)(ii).
Accordingly, for purposes of the statements and representations made hereunder,
Parent shall be treated as directly owning all of the assets and possessing
direct liability for all of the liabilities of Merger Sub and, except where the
letter specifically refers to Merger Sub, the separate existence of the Merger
Sub shall be disregarded and all references to Parent shall include all of
Merger Sub's assets, liabilities and activities.

          In connection with such opinions to be rendered by each of you, and
acknowledging that each of you will rely, with Company's consent, upon the
statements and representations made in this letter in rendering such opinions,
the undersigned hereby certifies and represents to each of you on behalf of
Company, after due investigation and inquiry, that the statements and
representations stated herein are true, correct and complete in all respects at
the date hereof and, except to the extent written notification to the contrary
is received by each of you before the Effective Time, will be true, correct and
complete in all respects as of the Effective Time (as if made as of the
Effective Time):

          1. The facts relating to the Merger, as such facts are described in
the registration statement on Form S-4 and the Proxy, insofar as such facts
pertain to Company, are true, correct and complete in all material respects, and
insofar as such facts pertain to Parent and Merger Sub, the undersigned has no
reason to believe that such facts are not true, correct and complete in all
material respects. Other than those described or referenced in the Merger
Agreement, there are no agreements, arrangements or understandings, either
written or oral, between or among (a) any of the Company, its subsidiaries,
affiliates or stockholders, on the one hand, and (b) any of Parent, its
subsidiaries, affiliates or stockholders on the other hand, concerning the
Merger.

          2. The Merger will be consummated solely in compliance with the
material terms and conditions of the Agreement and none of the material terms
and conditions thereof will be waived or modified.

          3. The fair market value of Parent Common Stock and cash in lieu of
fractional Parent Common Stock received by each holder of Company Common Stock
will be approximately equal to the fair market value of Company Common Stock
surrendered by such stockholder in the Merger. In connection with the Merger, no
holder of Company Common Stock will receive in exchange for Company Common
Stock, directly or indirectly, any consideration other than Parent Common Stock
and cash in lieu of fractional shares thereof. No liabilities of Company (other
than pursuant to the Merger or as set forth in the Agreement) or Company
stockholders will be assumed by Parent (or any corporation related to Parent).

          4. Prior to the Effective Time and in connection with the Merger,
Company has neither (i) redeemed, directly or indirectly, any of its stock, nor
(ii) made any distributions with respect to its stock. Additionally, prior to
the Effective Time and in connection with the Merger, no corporation related to
Company has acquired Company's stock. For purposes of this representation
letter, two corporations shall be treated as related to one another if,
immediately prior to or immediately after the Merger, (a) the corporations are
members of the same affiliated group (within the meaning of section 1504 of the
Internal Revenue Code of 1986, as amended (the "Code"), but determined without
regard to section 1504(b) of the Code) or (b) one corporation owns 50 percent or
more of the total combined voting power of all classes of stock of the other
corporation that are entitled to vote or 50 percent or more of the total value
of shares of all classes of stock of the other corporation (applying the
attribution rules of section 318 of the Code as modified pursuant to section
304(c)(3)(B) of the Code). For purposes of this representation letter, a
corporation that is a partner in a partnership for U.S. federal income tax
purposes will be treated as owning or acquiring any stock owned or acquired, as
the case may be, by the partnership and as having furnished its share of any
consideration furnished by the partnership to acquire the stock, in each case,
in accordance with its interest in the partnership.

          5. To the best knowledge of the management of Company, there is no
plan or intention on the part of stockholders of Company to sell, exchange or
otherwise transfer ownership of (including by derivative transactions such as an
equity swap which would have the economic effect of a transfer of ownership) any
Parent Common Stock (other than fractional Parent Common Stock for which holders
of Parent Common Stock receive cash in the Merger) to Parent or any corporation
related to Parent, directly or indirectly (including through partnerships or
through third parties in connection with a plan to so transfer ownership).

          6. No assets of Company have been sold, transferred or otherwise
disposed of so as to prevent Parent from continuing a "significant line" of
Company's "historic business" or from using a "significant portion" of Company's
"historic business assets" in a business following the Merger, as such terms are
used in Treasury Regulation section 1.368-1(d).

          7. Each of Company and its stockholders has paid and will pay only
their respective expenses, if any, incurred in connection with the Merger, other
than expenses of the Company paid by Parent that are solely and directly related
to the Merger in accordance with Revenue Ruling 73-54, 1973-1 C.B. 187.

          8. There is no intercorporate indebtedness existing between Parent and
Company that was issued, acquired or will be settled at or prior to the
Effective Time at a discount.

          9. Company will not (i) elect, or have in effect an election, to be
treated as a "regulated investment company" or as a "real estate investment
trust" or file any tax return consistent with such treatment or (ii) be a
corporation 50 percent or more of the fair market value of whose total assets
are stock or securities and 80 percent or more of the fair market value of whose
total assets are assets held for investment. In making the determinations
described in (ii) above, (x) the stock and securities of any subsidiary of
Company shall be disregarded and Company shall be deemed to own its ratable
share of such subsidiary's assets and (y) a corporation shall be considered to
be a subsidiary of Company if Company owns 50 percent or more of the combined
voting power of all classes of the stock of such subsidiary that are entitled to
vote, or 50 percent or more of the total value of all classes of the outstanding
stock of such subsidiary. In addition, in determining the fair market value of
Company's total assets for the purposes of making this representation, Company
shall exclude any cash and cash items (such as receivables), and U.S. federal
government securities.

          10. Company is not, and will not be, a debtor under the jurisdiction
of a court in a case under Title 11 of the United States Code or a receivership,
foreclosure or similar proceeding in a federal or state court.

          11. At the Effective Time, the fair market value of the assets of
Company will equal or exceed the sum of Company's liabilities plus (without
duplication) the amount of liabilities, if any, to which its assets are or will
be subject.

          12. The liabilities of Company assumed by Parent (pursuant to the
Merger or under the Agreement) and the liabilities to which the transferred
assets of Company are subject were incurred by Company in the ordinary course of
its business.

          13. None of the compensation to be received by any
stockholder-employees of Company for services rendered prior to the Effective
Time was or will be separate consideration for, or allocable to, any of such
stockholder-employee's shares of Company Common Stock; none of the Parent Common
Stock to be received by any stockholder-employees of Company in the Merger will
be separate consideration for, or allocable to, any employment, consulting or
similar agreement or arrangement with respect to services rendered prior to the
Effective Time; and the compensation paid to any stockholder-employees of
Company for services rendered prior to the Effective Time will be for services
actually rendered (or to be rendered) and was or will be commensurate with
amounts paid to third parties bargaining at arm's-length for similar services.

          14. Company is not currently, and during the five years preceding the
Effective Time will not have been, a corporation with respect to which the fair
market value of its United States real property interests equals or exceeds
fifty percent of the total fair market value of (i) its United States real
property interests, (ii) its interests in real property located outside the
United States and (iii) any other of its assets which are used or held for use
in a trade or business.

          15. Parent will acquire at least 90 percent of the fair market value
of the net assets and at least 70 percent of the fair market value of the gross
assets held by the Company immediately prior to the Merger. For purposes of this
representation, (A) amounts paid by the Company to dissenters, amounts paid by
the Company to shareholders (including cash in lieu of fractional shares of
Parent Common Stock), Company assets used to pay its Reorganization Expenses,
satisfy any Company indebtedness, and pay all redemptions and distributions
(except for regular, normal dividends) made by the Company immediately prior to
the Merger will be included as assets of the Company held immediately prior to
the Merger and (B), "Reorganization Expenses" means all costs, payments,
benefits and expenses that are triggered by, or incurred in connection with the
Merger or the consummation of any other transactions contemplated by the
Agreement, including, without limitation, all Expenses (as defined in the
Agreement) and any change of control and severance payments.

          16. Parent does not own, directly or indirectly, and has not owned
during the past five years, directly or indirectly, any stock of the Company.

          17. The total cash consideration that will be paid in the Merger to
stockholders of Company instead of issuing fractional Parent Common Stock will
not exceed one percent of the total consideration that will be issued in the
Merger to stockholders of Company in exchange for their shares of Company Common
Stock. The fractional share interests of each stockholder of Company will be
aggregated, and no stockholder of Company will receive cash in lieu of
fractional shares in an amount equal to or greater than the value of one full
Parent Common Share, except for any case in which a Company stockholder holds
beneficial interests in shares of Company Common Stock through more than one
brokerage account and such multiple accounts cannot be aggregated, either
because the beneficial interest cannot be identified or it would be impractical
to do so.

          18. Prior to the Effective Time, neither the Company nor any
subsidiary of the Company distributed the stock of any corporation in a
distribution of stock qualifying for tax-free treatment under Section 355 of the
Code.

          19. There will be no dissenters to the Merger.

          20. Company will not take any position on or with respect to any
federal, state, local or foreign tax return, that is inconsistent with the
treatment of the Merger as a reorganization within the meaning of Section 368(a)
of the Code, unless otherwise required by a "determination" (as defined in
Section 1313(a) of the Code) or by applicable state, local or foreign tax law.

          21. The undersigned is authorized to make all of the statements and
representations set forth herein on behalf of Company. The undersigned will
promptly notify Cleary, Gottlieb, Steen & Hamilton and O'Melveny and Myers LLP
if any of the above representations or covenants cease to be accurate and
complete.

                                      Very truly yours,

Cleary, Gottlieb, Steen & Hamilton

O'Melveny and Myers LLP

Ladies and Gentlemen:

          We refer to the Agreement and Plan of Merger dated as of December 3,
2001 (the "Agreement") by and among Synopsys, Inc. ("Parent"), a Delaware
corporation, Maple Forest Acquisition L.L.C. ("Merger Sub"), a Delaware limited
liability company that is wholly-owned by Parent and a company that is and will
be treated as a disregarded entity for U.S. federal income tax purposes and
Avant! Corporation (the "Company"), a Delaware corporation, which provides,
among other things, for the merger (the "Merger") of the Company with and into
Merger Sub, on the terms and conditions set forth therein, the time at which the
Merger becomes effective being hereafter referred to as the "Effective Time."
The Agreement requires that, as a condition to the consummation of the Merger,
Cleary, Gottlieb, Steen & Hamilton, counsel to the Parent and O'Melveny and
Myers LLP, counsel to the Company, render opinions regarding certain United
States federal income tax consequences of the Merger. Capitalized terms not
defined herein have the meanings specified in the Agreement. This letter assumes
the accuracy of Representation 3, below, and therefore is based on the
assumption that Merger Sub will be classified as a disregarded entity within the
meaning of Treasury regulation section 301.7701-3(b)(ii). Accordingly, for
purposes of the statements and representations made hereunder, Parent shall be
treated as directly owning all of the assets and possessing direct liability for
all of the liabilities of Merger Sub and, except where the letter specifically
refers to Merger Sub, the separate existence of Merger Sub shall be disregarded
and all references to Parent shall include all of Merger Sub's assets,
liabilities and activities.

          In connection with the opinions to be rendered by each of you, and
acknowledging that each of you will rely, with Parent's and Merger Sub's
consent, upon the statements and representations made in this letter in
rendering such opinions, each of the undersigned certifies and represents to
each of you on behalf of Parent and Merger Sub, respectively, after due
investigation and inquiry that the statements and representations stated herein
are true, correct and complete in all respects at the date hereof and, except to
the extent written notification to the contrary is received by each of you
before the Effective Time, will be true, correct and complete in all respects as
of the Effective Time (as if made as of the Effective Time):

          1. The facts relating to the Merger, as such facts are described in
the registration statement on Form S-4 and the Proxy, insofar as such facts
pertain to Parent and Merger Sub, are true, correct and complete in all material
respects, and insofar as such facts pertain to Company, the undersigned have no
reason to believe that such facts are not true, correct and complete in all
material respects. Other than those described or referenced in the Merger
Agreement, there are no agreements, arrangements or understandings, either
written or oral, between or among (a) any of Parent, its subsidiaries,
affiliates or stockholders, on the one hand, and (b) any of the Company, its
subsidiaries, affiliates or stockholders on the other hand, concerning the
Merger.

          2. The Merger will be consummated solely in compliance with the
material terms and conditions of the Agreement and none of the material terms
and conditions thereof will be waived or modified.

          3. Prior to the Merger, Parent will own all of the outstanding
ownership interests of Merger Sub. Merger Sub has not made and following the
Merger does not intend to make an election on Form 8832, pursuant to Treasury
Regulation section 301.7701-3(c)(1)(i), to be classified as an association
taxable as a corporation for United States federal income tax purposes. Merger
Sub has always been and currently is classified as a disregarded entity within
the meaning of Treasury Regulation section 301.7701-3(b)(ii) for U.S. federal
income tax purposes.

          4. The fair market value of Parent Common Stock and cash in lieu of
fractional Parent Common Stock received by each holder of Company Common Stock
will be approximately equal to the fair market value of Company Common Stock
surrendered by such stockholder in the Merger. In connection with the Merger, no
holder of Company Common Stock will receive in exchange for Company Common
Stock, directly or indirectly, any consideration other than Parent Common Stock
and cash in lieu of fractional shares thereof. No liabilities of Company (other
than pursuant to the Merger or as set forth in the Agreement) or Company
stockholders will be assumed by Parent (or any corporation related to either of
them).

          5. Neither Parent nor any corporation related to Parent will, in
connection with the Merger, (i) be under any obligation, or will have entered
into any agreement or understanding, directly or indirectly, to redeem or
repurchase any of the Parent shares issued to stockholders of Company in the
Merger or to make any extraordinary distribution in respect of such Parent
shares or (ii) have any plan or intention, directly or indirectly, to reacquire
any of the Parent shares issued in the Merger. There will be no dissenters to
the Merger. After the Merger, no dividends or distributions will be made to the
former Company stockholders by Parent other than regular, normal dividends or
distributions made to all holders of Parent Common Stock. For purposes of this
representation letter, two corporations shall be treated as related to one
another if immediately prior to or immediately after the Merger, (a) the
corporations are members of the same affiliated group (within the meaning of
section 1504 of the Internal Revenue Code of 1986, as amended (the "Code"), but
determined without regard to section 1504(b) of the Code) or (b) one corporation
owns 50 percent or more of the total combined voting power of all classes of
stock of the other corporation that are entitled to vote or 50 percent or more
of the total value of all classes of stock of the other corporation (applying
the attribution rules of Section 318 of the Code as modified pursuant to section
304(c)(3)(B) of the Code). For purposes of this representation letter, a
corporation that is a partner in a partnership for U.S. federal income tax
purposes will be treated as owning or acquiring any stock owned or acquired, as
the case may be, by the partnership and as having furnished its share of any
consideration furnished by the partnership to acquire the stock, in each case,
in accordance with its interest in the partnership.

          6. Neither Parent nor any corporation related to Parent (nor any
permitted transferee corporation or partnership, described below) has any plan
to sell, distribute, transfer or otherwise dispose of any Parent assets acquired
from Company, except for (A) dispositions made in the ordinary course of
business (B) transfers by Parent (including successive transfers by permitted
corporate transferees) of assets to one or more corporations controlled, in the
case of each transfer, by the transferor corporation, or (C) transfers by Parent
(including successive transfers by permitted corporate transferees) to one or
more partnerships in which the transferor corporation is a partner and members
of Parent's qualified group either (i) own a significant interest or (ii) own a
20 percent or greater interest and have active and substantial management
functions as a partner with respect to that partnership business. Except as
otherwise permitted under this representation, Parent will own all outstanding
ownership interests of Merger Sub immediately after the Merger and Parent has no
plan or intention to cause or permit Merger Sub to issue additional ownership
interests to any person or entity (other than Parent). After the Merger, Merger
Sub will not have outstanding any warrants, options, convertible securities, or
any other type of right pursuant to which any person could acquire interests in
Merger Sub. For purpose of clause (B) of this representation, "controlled" with
respect to a corporation shall mean direct ownership of at least (i) 80 percent
of the total combined voting power of all classes of stock entitled to vote and
(ii) 80 percent of the total number of shares of each other class of stock of
the corporation.

          7. Following the Merger, Parent or a member of Parent's "qualified
group" will continue a "significant line" of the "historic business" of Company
or use a "significant portion" of Company's "historic business assets" in a
business, as such terms are used in Treasury Regulation section 1.368-1(d). For
purposes of this representation, Parent's "qualified group" means, pursuant to
Treasury Regulation section 1.368-1(d)(4)(ii), one or more chains of
corporations connected through stock ownership with Parent, but only if Parent
owns directly stock representing control in at least one other corporation, and
stock representing control in each of the corporations (except Parent) is owned
directly by one of the other corporations. In addition, Parent will be treated
as owning its proportionate share of Company's business assets used in a
business of any partnership in which members of Parent's qualified group either
(i) own a significant interest or (ii) own a 20 percent or greater interest and
have active and substantial management functions as a partner with respect to
that partnership business.

          8. Parent has paid and will pay its expenses, if any, incurred in
connection with the Merger, other than expenses of the Company paid by Parent
that are solely and directly related to the Merger in accordance with Revenue
Ruling 73-54, 1973-1 C.B. 187. Neither Parent nor any corporation related to
Parent has agreed to assume, or will assume, directly or indirectly, any expense
or other liability, whether fixed or contingent, of any holder of Company stock
as consideration for Company Common Stock surrendered pursuant to the Merger or
any related transaction.

          9. There is no intercorporate indebtedness existing between Parent and
Company that was issued, acquired or will be settled at or prior to the
Effective Time at a discount or, to the best knowledge of Parent, will be
settled after the Effective Time at a discount.

          10. Parent will not (i) elect, or have in effect an election, to be
treated as a "regulated investment company" or as a "real estate investment
trust" or file any tax return consistent with such treatment or (ii) at the
Effective Time, be an entity 50 percent or more of the fair market value of
whose total assets are stock or securities and 80 percent or more of the fair
market value of whose total assets are assets held for investment. In making the
determinations described in (ii) above, (x) the stock and securities of any
subsidiary of Parent shall be disregarded and Parent shall be deemed to own its
ratable share of such subsidiary's assets and (y) a corporation shall be
considered to be a subsidiary of Parent if Parent owns 50 percent or more of the
combined voting power of all classes of the stock of such subsidiary that are
entitled to vote, or 50 percent or more of the total value of all classes of the
outstanding stock of such subsidiary. In addition, in determining the fair
market value of Parent's total assets for the purposes of making this
representation, Parent shall exclude any cash and cash items (such as
receivables), and U.S. federal government securities.

          11. None of the compensation to be received by any
stockholder-employees of Company from Parent (or any corporation related to
Parent) for services rendered after the Effective Time, and none of the
compensation to be received by any stockholder-employees of Company from Company
for services rendered either before or after the Effective Time, will be
separate consideration for, or allocable to, any of such stockholder-employee's
shares of Company stock; none of the Parent Common Stock to be received by any
stockholder-employees of Company in connection with the Merger will be separate
consideration for, or allocable to, any employment, consulting or similar
agreement or arrangement with respect to services rendered after the Effective
Time; and the compensation paid to any stockholder-employees of Company for
services rendered will be for services actually rendered (or to be rendered) and
will be commensurate with amounts paid to third parties bargaining at
arm's-length for similar services.

          12. Parent will acquire at least 90 percent of the fair market value
of the net assets and at least 70 percent of the fair market value of the gross
assets held by the Company immediately prior to the Merger. For purposes of this
representation, (A) amounts paid by the Company to dissenters, amounts paid by
the Company to shareholders (including cash in lieu of fractional shares of
Parent Common Stock), Company assets used to pay its Reorganization Expenses,
satisfy any Company indebtedness, and pay all redemptions and distributions
(except for regular, normal dividends) made by the Company immediately prior to
the Merger will be included as assets of the Company held immediately prior to
the Merger and (B), "Reorganization Expenses" means all costs, payments,
benefits and expenses that are triggered by, or incurred in connection with the
Merger or the consummation of any other transactions contemplated by the
Agreement, including, without limitation, all Expenses (as defined in the
Agreement) and any change of control and severance payments.

          13. The payment of cash in lieu of fractional Parent Common Stock that
would otherwise be issued to stockholders of Company in the Merger is solely for
the purpose of avoiding the expense and inconvenience to Parent of issuing and
transferring fractional Parent Common Stock and does not represent separately
bargained-for consideration. The total cash consideration that will be paid in
the Merger to stockholders of Company instead of issuing fractional Parent
Common Stock will not exceed one percent of the total consideration that will be
issued in the Merger to stockholders of Company in exchange for their shares of
Company Common Stock. The fractional share interests of each stockholder of
Company will be aggregated, and no stockholder of Company will receive cash in
lieu of fractional shares in an amount equal to or greater than the value of one
full Parent Common Stock, except for any case in which a Company stockholder
holds beneficial interests in shares of Company Common Stock through more than
one brokerage account and such multiple accounts cannot be aggregated, either
because the beneficial interest cannot be identified or it would be impractical
to do so.

          14. Parent does not own, directly or indirectly, and has not owned
during the past five years, directly or indirectly, any stock of the Company.

          15. To the best knowledge of Parent and Merger Sub, the liabilities of
the Company assumed by Parent (pursuant to the Merger or under the Agreement)
and the liabilities to which the transferred assets of the Company are subject
were incurred by the Company in the ordinary course of its business.

          16. To the best knowledge of Parent and Merger Sub, at the Effective
Time, the fair market value of the assets of the Company will exceed the sum of
its liabilities plus the liabilities, if any, to which the assets are subject.

          17. After the Merger, Parent will comply with the record-keeping and
information filing requirements of Treasury Regulation section 1.368-3. Parent
will not take any position on or with respect to any federal, state, local or
foreign tax return, that is inconsistent with the treatment of the Merger as a
reorganization within the meaning of Section 368(a) of the Code, unless
otherwise required by a "determination" (as defined in Section 1313(a) of the
Code) or by applicable state, local or foreign tax law.

          18. Each of the undersigned is authorized to make all of the
statements and representations set forth herein on behalf of Parent and Merger
Sub, respectively. The undersigned will promptly notify Cleary Gottlieb, Steen &
Hamilton and O'Melveny and Myers LLP if any of the above representations or
covenants cease to be accurate and complete.

                                            Very truly yours,

                                            Synopsys, Inc.
