AGREEMENT OF MERGER AND PLAN OF REORGANIZATION

This AGREEMENT OF MERGER AND PLAN OF REORGANIZATION (the "Agreement")
is made and entered into as of July 8, 1994 among Cadence Design Systems, Inc.,
a Delaware corporation ("Parent"), Simon Software, Inc., a California
corporation ("Merger Sub") and a wholly-owned subsidiary of Parent, and Redwood
Design Automation, Inc., a California corporation (the "Company").

RECITALS

A. The Boards of Directors of each of the Company, Parent and
Merger Sub believe it is in the best interests of each company and their
respective shareholders that the Company and Merger Sub combine into a single
company through the statutory merger of Merger Sub with and into the Company
(the "Merger") and, in furtherance thereof, have approved the Merger.

B. Pursuant to the Merger, among other things, the outstanding
shares of Preferred Stock of the Company shall be converted into shares of
Common Stock of Parent ("Parent Common Stock") at the rate determined herein.
(The shares of Series A Preferred Stock, Series B Preferred Stock, together
with Series C Preferred Stock of the Company are collectively referred to
herein as the "Company Preferred Stock"). As a result of the Merger, Parent
will own all capital stock and rights to acquire capital stock of the Company.

C. The Company, Parent and Merger Sub desire to make certain
representations and warranties and other agreements in connection with the
Merger.

NOW, THEREFORE, in consideration of the covenants, promises and
representations set forth herein, and for other good and valuable
consideration, the parties agree as follows:

ARTICLE I
THE MERGER

1.1 The Merger. At the Effective Time (as defined in Section 1.2)
and subject to and upon the terms and conditions of this Agreement and
California law, Merger Sub shall be merged with and into the Company, the
separate corporate existence of Merger Sub shall cease and the Company shall
continue as the surviving corporation. The Company as the surviving
corporation after the Merger is hereinafter referred to as the "Surviving
Corporation."

1.2 Effective Time. As promptly as practicable after the
satisfaction or waiver of the conditions set forth in Article VI, the parties
hereto shall cause the Merger to be consummated by filing an Agreement of
Merger (the "Agreement of Merger") with the Secretary of State of the State of
California, in such form as required by, and executed in accordance with the
relevant provisions of, California law (the time of such filing being the
"Effective Time"). The closing of the transactions contemplated hereby (the
"Closing") shall take place at 10:00 a.m. at the Palo Alto offices of Fenwick
& West, on the date of the proposed Effective Time (the "Closing Date").
Without limiting the foregoing, for the purposes of scheduling, the parties
anticipate that the Closing will take place prior to August 31, 1994.

1.3 Effect of the Merger. At the Effective Time, the effect of
the Merger shall be as provided in the applicable provisions of California law.
Without limiting the generality of the foregoing, and subject thereto, at the
Effective Time all the property, rights, privileges, powers and franchises of
the Company and Merger Sub shall vest in the Surviving Corporation, and all
debts, liabilities and duties of the Company and Merger Sub shall become the
debts, liabilities and duties of the Surviving Corporation.

<PAGE> 8
1.4 Articles of Incorporation; Bylaws.

(a) Unless otherwise determined by Parent prior to the
Effective Time, at the Effective Time the Articles of Incorporation of Merger
Sub, as in effect immediately prior to the Effective Time, shall be the
Articles of Incorporation of the Surviving Corporation until thereafter amended
as provided by law and such Articles of Incorporation; provided, however, that
Article I of the Articles of Incorporation of the Surviving Corporation shall
be amended to read as follows: "The name of the corporation is Redwood Design
Automation, Inc."

(b) The Bylaws of Merger Sub, as in effect immediately
prior to the Effective Time, shall be the Bylaws of the Surviving Corporation
until thereafter amended.

1.5 Directors and Officers. The directors of Merger Sub
immediately prior to the Effective Time shall be the initial directors of the
Surviving Corporation, each to hold office in accordance with the Articles of
Incorporation and Bylaws of the Surviving Corporation, and the officers of
Merger Sub immediately prior to the Effective Time shall be the initial
officers of the Surviving Corporation, in each case until their respective
successors are duly elected or appointed and qualified. All current officers
and directors of subsidiaries of the Company shall tender their resignations on
or before the Effective Time.

1.6 Maximum Shares to Be Issued; Effect on Capital Stock. The
maximum number of shares of Parent Common Stock to be issued in exchange for
the acquisition by Merger Sub of all outstanding Company Preferred Stock,
Common Stock of the Company ("Company Common Stock") and rights to acquire any
Company Preferred Stock or Company Common Stock, shall be determined
immediately prior to the Effective Time and shall be equal to the Aggregate
Share Number (as defined, along with certain other terms defined herein in
paragraph (f) below); provided that such maximum number shall be adjusted to
the extent required by paragraph (e) below. Subject to the terms and
conditions of this Agreement, as of the Effective Time, by virtue of the Merger
and without any action on the part of Merger Sub, the Company or the holder of
any of the following securities:

(a) Conversion of Preferred Stock. Each share of Company
Preferred Stock issued and outstanding immediately prior to the Effective Time
(other than any shares of Company Preferred Stock to be canceled pursuant to
Section 1.6(c) and any Dissenting Shares (as defined and to the extent provided
in Section 1.7(a)) will be canceled and extinguished and be converted
automatically into the right to receive that number of shares of Parent Common
Stock equal to the amount set forth in the following table, with the
replacement Parent certificate or certificates to be issued upon surrender of
the certificate representing such share of Company Preferred Stock in the
manner provided in Section 1.8, including, with respect to each whole share of
Parent Common Stock to be received, the right to receive one Share Purchase

<PAGE> 9
(b) Cancellation of Common Stock and Options or Other
Rights to Purchase Common Stock or Preferred Stock. Each share of Company
Common Stock issued and outstanding immediately prior to the Effective Time
shall be canceled and extinguished and shall not be converted into the right to
receive any consideration whatsoever by virtue of the Merger. Each option to
purchase Company Common Stock outstanding under the Company's 1991 Employee
Stock Plan (the "Stock Option Plan") and any other rights to acquire Company
Common Stock or Company Preferred Stock shall be canceled and terminated and
shall not be assumed by Parent or the Surviving Corporation. The foregoing
shall all be accomplished in accordance with the Company's Articles of
Incorporation, Bylaws, Stock Option Plan and other applicable contractual
obligations, as the case may be.

(c) Cancellation of Parent-Owned and Company-Owned Stock.
Each share of Company Preferred Stock owned by Merger Sub, Parent, the Company
or any direct or indirect wholly owned subsidiary of Parent or of the Company
immediately prior to the Effective Time shall be canceled and extinguished
without any conversion thereof.

(d) Capital Stock of Merger Sub. Each share of common
stock of Merger Sub issued and outstanding immediately prior to the Effective
Time shall be converted into one validly issued, fully paid and nonassessable
share of common stock of the Surviving Corporation. Each stock certificate of
Merger Sub evidencing ownership of any such shares shall continue to evidence
ownership of such shares of capital stock of the Surviving Corporation.

(e) Fractional Shares. If permitted under applicable
law, no fraction of a share of Parent Common Stock will be issued, but in lieu
thereof each holder of shares of Company Preferred Stock who would otherwise be
entitled to a fraction of a share of Parent Common Stock (after aggregating all
fractional shares of Parent Common Stock to be received by such holder) shall
not be entitled to receive from Parent any shares or fractional shares of
Parent Common Stock therefor; provided, however, in the event the fraction of a
share which any shareholder would otherwise be entitled to receive is one-half
of one percent or more of the total shares such shareholder is entitled to
receive, the holder thereof shall be entitled to receive an amount of cash
equal to that fraction of the Ten-Day Average Price, as defined in subparagraph
(f)(i) below.

(f) Definitions.

(i) Subject to the provisions of paragraph (e)
above and Section 1.7 below, the "Aggregate Share Number" shall be a number of
shares of Parent Common Stock equal to (a) 6,500,000 divided by (b) the average
closing price of a share of Parent Common Stock for the ten most recent days
that Parent Common Stock has traded ending on and including the trading day
three trading days prior to the Effective Time, on the New York Stock Exchange
(as reported in the Wall Street Journal) (the "Ten-Day Average Price");
provided, however, that if the Ten-Day Average Price is greater than $17.05 the
Ten-Day Average Price shall be deemed to be $17.05; and, provided further, that
if the Ten-Day Average Price is less than $13.95, then the Ten-Day Average
Price shall be deemed to be $13.95.

(ii) Escrow Number. The "Escrow Number" shall be
equal to 1,000,000 divided by the Ten-Day Average Price, rounded to the nearest
whole share.

(iii) Series A Allocation Number. The "Series A
Allocation Number" shall be equal to the Aggregate Share Number multiplied by
.0351.

-3-
<PAGE> 10
(iv) Series B Allocation Number. The "Series B
Allocation Number" shall be equal to the Aggregate Share Number multiplied by
.4815.

(v) Series C Allocation Number. The "Series C
Allocation Number" shall be equal to the Aggregate Share Number multiplied by
.4834.

(vi) Series A Exchange Number. The "Series A
Exchange Number" shall be equal to the Series A Allocation Number divided by
740,000.

(vii) Series B Exchange Number. The "Series B
Exchange Number" shall be equal to the Series B Allocation Number divided by
5,516,306.

(viii) Series C Exchange Number. The "Series C
Exchange Number" shall be equal to the Series C Allocation Number divided by
4,469,302.

The Series A Exchange Number, Series B Exchange Number and Series C
Exchange Number shall be adjusted to reflect fully the effect of any stock
split, reverse split, stock dividend (including any dividend or distribution of
securities convertible into Parent Common Stock or Company Preferred Stock),
reorganization, recapitalization or other like change with respect to Parent
Common Stock or Company Preferred Stock occurring after the date hereof and
prior to the Effective Time; provided, however, that the Repurchase described
in Section 5.10 below has been accounted for in determining the Series C
Exchange Number and shall not result in any additional adjustment.

1.7 Dissenting Shares.

(a) Notwithstanding any provision of this Agreement to
the contrary, any shares of capital stock of the Company held by a holder who
has demanded and perfected dissenters' rights for such shares in accordance
with California law (Corporations Code Chapter 13) and who, as of the Effective
Time, has not effectively withdrawn or lost such dissenters' rights
("Dissenting Shares"), shall not be converted into or represent a right to
receive Parent Common Stock pursuant to Section 1.6, but the holder thereof
shall only be entitled to such rights as are granted by California law.

(b) Notwithstanding the provisions of subsection (a), if
any holder of shares of capital stock of the Company who demands dissenters'
rights under California law shall effectively withdraw or lose (through failure
to perfect or otherwise) such rights dissenters' rights, then, as of the later
of the Effective Time and the occurrence of such event, such holder's Preferred
Stock shall automatically be converted into and represent only the right to
receive Parent Common Stock, without interest thereon, upon surrender of the
certificate representing such shares.

(c) The Company shall give Parent (i) prompt notice of
any written demands for dissenters' rights with respect to any shares of
capital stock of the Company, withdrawals of such demands, and any other
related instruments and documents received by the Company and (ii) the
opportunity to participate in all negotiations and proceedings with respect to
demands for cash settlement under California law. The Company shall not,
except with the prior written consent of Parent, voluntarily make any payment
with respect to any demands for dissenters' rights with respect to capital
stock of the Company or offer to settle or settle any such demands.

<PAGE> 11

(d) Parent reserves the right to delay delivery of Parent
Common Stock upon surrender of Company Preferred Stock to the Exchange Agent to
any Company shareholder which did not vote in favor of the Merger until such
shareholder's dissenters' rights pursuant to Chapter 13 of the California
Corporations Code have terminated. Exercise by any shareholder of such
dissenters' rights shall terminate the right to receive Parent Common Stock as
set forth in paragraph 1.6(a) hereof with respect to such dissenting shares.

1.8 Surrender of Certificates.

(a) Exchange Agent. Prior to the Effective Time, Parent
shall designate a bank or trust company to act as exchange agent (the "Exchange
Agent") in the Merger.

(b) Parent to Provide Common Stock. Promptly after the
Effective Time, Parent shall make available to the Exchange Agent for exchange
in accordance with this Article I the shares of Parent Common Stock issuable
pursuant to Section 1.6 in exchange for the surrender of the outstanding shares
of Company Preferred Stock and the cancellation of Company Common Stock and any
rights to purchase Company Common Stock or Company Preferred Stock.

(c) Exchange Procedures. Promptly after the Effective
Time, the Surviving Corporation shall cause to be mailed to each holder of
record of a certificate or certificates which immediately prior to the
Effective Time represented outstanding shares of Company Preferred Stock whose
shares were converted into the right to receive shares of Parent Common Stock
pursuant to Section 1.6 (the "Certificates"), (i) a letter of transmittal
(which shall specify that delivery shall be effected, and risk of loss and
title to the Certificates shall pass, only upon delivery of the Certificates to
the Exchange Agent and shall be in such form and have such other provisions as
Parent may reasonably specify) and (ii) instructions for use in effecting the
surrender of the Certificates in exchange for certificates representing shares
of Parent Common Stock. Upon surrender of a Certificate for cancellation to
the Exchange Agent or to such other agent or agents as may be appointed by
Parent, together with such letter of transmittal, duly completed and validly
executed in accordance with the instructions thereto, the holder of such
Certificate shall be entitled to receive in exchange therefor a certificate
representing the number of whole shares of Parent Common Stock (less the number
of shares of Parent Common Stock, if any, to be deposited in the Escrow Fund
on such holder's behalf pursuant to Article VII hereof) to which such holder is
entitled pursuant to Section 1.6, and the Certificate so surrendered shall
forthwith be canceled. As soon as practicable after the Effective Time, and
subject to and in accordance with the provisions of Article VII hereof, Parent
shall cause to be distributed to the Escrow Agent (as defined in Article VII) a
certificate or certificates representing that number of shares of Parent Common
Stock equal to the Escrow Number which shall be registered in the name of the
Escrow Agent. Such shares shall be beneficially owned by the holders on whose
behalf such shares were deposited in the Escrow Fund and shall be available to
compensate Parent as provided in Article VII. Until so surrendered, each
outstanding Certificate that, prior to the Effective Time, represented shares
of Company Preferred Stock will be deemed from and after the Effective Time,
for all corporate purposes, other than the payment of dividends, to evidence
the ownership of the number of full shares of Parent Common Stock into which
such shares of Company Preferred Stock shall have been so converted in
accordance with Section 1.6 and subject to the limitations of Article VII.

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

(e) Transfers of Ownership. If any certificate for
shares of Parent Common Stock is to be issued in a name other than that in
which the Certificate surrendered in exchange therefor is registered, it will
be a condition of the issuance thereof that the Certificate so surrendered will
be properly endorsed and otherwise in proper form for transfer and that the
person requesting such exchange will have paid to Parent or any agent
designated by it any transfer or other taxes required by reason of the issuance
of a certificate for shares of Parent Common Stock in any name other than that
of the registered holder of the Certificate surrendered, or established to the
satisfaction of Parent or any agent designated by it that such tax has been
paid or is not payable. Parent can also require indemnification in such
instances in form and substance acceptable to Parent.

(f) No Liability. Notwithstanding anything to the
contrary in this Section 1.8, none of the Exchange Agent, the Surviving
Corporation, the Escrow Agent, the Agent, the Company, Parent or Merger Sub or
any party hereto shall be liable to a holder of shares of Parent Common Stock,
Company Preferred Stock or Company Common Stock for any amount properly paid to
a public official pursuant to any applicable abandoned property, escheat or
similar law.

1.9 No Further Ownership Rights in Company Common Stock. All
shares of Parent Common Stock issued upon the surrender for exchange of shares
of Company Preferred Stock in accordance with the terms hereof (including any
cash paid in respect thereof) shall be deemed to have been issued in full
satisfaction of all rights pertaining to such shares of Company Preferred
Stock, and there shall be no further registration of transfers on the records
of the Surviving Corporation of shares of Company Preferred Stock or Company
Common Stock which were outstanding immediately prior to the Effective Time.
If, after the Effective Time, Certificates are presented to the Surviving
Corporation for any reason, they shall be canceled and, in the case of Company
Preferred Stock, exchanged, as provided in this Article I.

1.10 Lost, Stolen or Destroyed Certificates. In the event any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent
shall issue in exchange for such lost, stolen or destroyed Certificates, upon
the making of an affidavit of that fact by the holder thereof, such shares of
Parent Common Stock as may be required pursuant to Section 1.6; provided,
however, that Parent may, in its discretion and as a condition precedent to the
issuance thereof, require the owner of such lost, stolen or destroyed
certificates to deliver a bond in such sum as it may reasonably direct as
indemnity against any claim that may be made against Parent or the Exchange
Agent with respect to such Certificates.

1.11 Taking of Necessary Action; Further Action. If, at any time
after the Effective Time, any such further action is necessary or desirable to
carry out the purposes of this Agreement and to vest the Surviving Corporation
with full right, title and possession to all assets, property, rights,
privileges, powers and franchises of the Company and Merger Sub, the officers
and directors of the Company and Merger Sub are fully authorized in the name of
their respective corporations or otherwise to take, and will take, all such
lawful and necessary action.

registered trademarks, service marks and copyrights held by the Company are

the business of the Company does not violate the proprietary rights of any
third party. To the knowledge of the Company, after reasonable inquiry, the
Company is the sole and exclusive owner of the products of the Company set
forth on Schedule 2.9 hereof and is not contractually obligated to pay
compensation to any third party in respect of the license of any of such
products to its customers. To the knowledge of the Company, there is no
material unauthorized use, infringement or misappropriation of any of the

action or proceeding which involves a claim of infringement of any patents,
trademarks, service marks, copyrights or violation of any trade secret or other
proprietary right of any third party and which has not been finally terminated
prior to the date hereof nor does it have any knowledge of any such charge or
claim, and there is not any infringement liability with respect to, or
infringement or violation by, the Company of any patent, trademark, service
mark, copyright, trade secret or other proprietary right of another. To the
Company's knowledge, no Company Intellectual Property Right or product of the

Company's products and related trademarks, technology and know-how. To the
Company's knowledge, the Company has not breached or violated the terms of its
license, sublicense or other agreement relating to any Commercial Software
Rights and has a valid right to use such Commercial Software Rights and has a
valid right to use such Commercial Software Rights under such license and
agreements. The Company is not, nor will it be as a result of the execution
and delivery of this Agreement or the performance of its obligations hereunder,
in violation of any license, sublicense or agreement relating to Commercial
Software Rights. No claims with respect to the Commercial Software Rights have
been asserted or, to the knowledge of the Company, are threatened by any person

rights in, all material Company Intellectual Property Rights. To the best of
the Company's knowledge, no current or prior officers, employees or consultants
of the Company claim an ownership interest in any Company Intellectual
Property Rights as a result of having been involved in the development of such
property while employed by or consulting to the Company, or otherwise. To the
best of the Company's knowledge, all officers, employees and consultants of the
Company or any of the Company's subsidiaries have executed and delivered to the
Company an agreement regarding the protection of proprietary information and
the assignment to the Company of all intellectual property developed as an
employee or consultant of the Company.

existing and in good standing under the laws of the State of California. Each
of Parent and Merger Sub has the corporate power to own its properties and to

Certificate (or Articles, as the case may be) of Incorporation and Bylaws of
each of Parent and Merger Sub, as amended to date, to counsel for the Company.

The execution and delivery of this Agreement do not, and the consummation of

obligation or to loss of a material benefit under (i) any provision of the
Certificate (or Articles, as the case may be) of Incorporation or Bylaws of
Parent and Merger Sub or (ii) any mortgage, indenture, lease, contract or other
agreement or instrument, permit, concession, franchise, license, judgment,
order, decree, statute, law, ordinance, rule or regulation applicable to Parent

order or authorization of, or registration, declaration or filing with, any
Governmental Entity, is required by or with respect to Parent and Merger Sub in
connection with the execution and delivery of this Agreement by Parent and

authorizations, registrations, declarations and filings as may be required

to make the statements made therein, in light of the circumstances in which
they were made, not misleading, except to the extent corrected by a document
subsequently filed with the SEC prior to the date hereof. The financial
statements of Parent, including the notes thereto, included in the SEC

contemplated hereby shall not be consummated, all such information which shall
be in writing shall be returned to the party furnishing the same, including to
the extent reasonably practicable, copies or reproductions thereof which may
have been prepared.

5.3 Expenses. Whether or not the Merger is consummated, all
expenses incurred in connection with the Merger and this Agreement ("Expenses")
shall be the obligation of the party incurring such expenses; provided,
however, that the attorneys fees and expenses payable by the Company in
connection with the transactions contemplated hereby shall be based on regular
hourly rates and actual out-of-pocket expenses and, if the Merger is
consummated, shall not exceed $75,000. If the Merger is consummated, attorneys
fees and expenses of Company counsel up to such amount shall be paid no later
than such fees and expenses of Parent counsel are paid.

5.4 Public Disclosure. Unless otherwise required by law, prior to
the Effective Time no disclosure (whether or not in response to an inquiry) of
the subject matter of this Agreement shall be made by any party hereto unless
approved by Parent and the Company prior to release, provided that such

to Parent's obligation to comply with applicable securities laws.

5.5 Consents. Each of Parent and the Company shall promptly apply
for or otherwise seek, and use its best efforts to obtain, all consents and
approvals required to be obtained by it for the consummation of the Merger, and

5.6 Legal Requirements. Each of Parent, Merger Sub and the

-22-
<PAGE> 29

Governmental Entity or other person, required to be obtained or made in

request of another party hereto, shall execute and deliver such other
instruments and do and perform such other acts and things as may be reasonably
necessary or desirable for effecting completely the consummation of this
Agreement and the transactions contemplated hereby.

5.9 Registration Rights Agreement. Prior to the Effective Time,
Parent, the Company and those shareholders of the Company who will receive
Parent Common Stock in the Merger and who desire to sell such Parent Common
Stock pursuant to a registration statement shall enter into a Registration
Rights Agreement (the "Registration Rights Agreement") substantially in the
form of Exhibit 1 hereto. The Parent Common Stock to be issued by Parent
pursuant to the Merger has not been registered under the Securities Act of
1933, as amended (the "Securities Act") and constitutes "restricted securities"
under Rule 144(d) of the Securities Act, and has been issued in reliance on the
exemptions for non-public offerings provided by Rule 506 and Section 4(2) of
the Securities Act. The Company shareholders who sign the Registration Rights
Agreement will have certain rights to cause the Parent Common Stock issued in
the Merger to be registered by Parent for resale. Unless a shareholder signs
the Registration Rights Agreement, the Holder will not be able to publicly sell
the shares until two years after the Closing Date. After that date, the holder
may sell the shares under Rule 144 promulgated under the Securities Act (which
permits limited public resale of "restricted securities," subject to the
satisfaction of certain conditions) in the event all of the applicable
requirements of Rule 144 are satisfied (otherwise registration under the
Securities Act or some other exemption from the registration requirements of
the Securities Act will be required in order to dispose of such shares). In no
event shall the Parent Common Stock be sold within the first year after the
Effective Time and in the event of any transfer of the Parent Common Stock,
whether by operation of law or otherwise, any transferee shall hold such shares
subject to the restrictions herein. The certificates representing the Parent
Common Stock issued in the Merger may contain legends to the foregoing effect.
In order to ensure compliance with the restrictions referred to herein, Parent
may issue appropriate "stop transfer" instructions to its transfer agent.
Parent shall not be required (i) to transfer or have transferred on its books
any Common Stock that has been sold or otherwise transferred in violation of
any of the provisions of this Agreement or the Registration Rights Agreement or
(ii) to treat as owner of such Common Stock or to accord the right to vote or
pay dividends to any purchaser or other transferee to whom such Common Stock
shall have been so transferred in violation of any provision of this Agreement
or the Registration Rights Agreement. Parent agrees that such stop transfer
instructions and legends will be promptly removed if the provisions of the
Registration Rights Agreement and the Securities Act are complied with.

5.10 NED Buyback. Effective as of the Closing Date, subject to the
Closing and the Company having sufficient cash reserves, the Company shall
repurchase 438,597 shares of Series C Preferred Stock from Nippon Enterprise
Development Corp. ("NED") for an aggregate of $500,000 (the "Repurchase"). The

-23-
<PAGE> 30

Repurchase shall be effected immediately prior to the Effective Time for the
purpose of rescinding the issuance of such Series C Preferred Stock to NED on
April 27, 1994, and documentation reflecting the foregoing shall be in form and
substance reasonably satisfactory to Parent.

5.11 Advance of Funds. In connection with the Merger contemplated
hereunder, Parent has agreed to advance $2,500,000 to the Company, $1,000,000
of which was paid upon execution of a Letter of Intent dated June 3, 1994 (the
"Letter of Intent"). In accordance with the terms set forth in the Letter of
Intent, an additional $1,500,000 will be advanced to the Company upon execution
of this Agreement, subject to establishment of an escrow of the Company's
technology on terms suitable to Parent and the Company and sufficient to permit
Parent to exercise its license rights described below. The Company hereby
represents that it will establish an escrow of technology pursuant to the
Technology Escrow Agreement in the form attached hereto as Exhibit 2 effective
as of the date hereof. The Company will deliver the $1,500,000 upon notice
from the escrow holder that the escrow has been established. The Company
agrees that such funds will be used as working capital and for general
corporate purposes and pursuant to the provisions of this Agreement. Such
advances shall be structured as indebtedness, bearing interest at a mutually
acceptable rate and repayable two years after issuance of the promissory note
evidencing such indebtedness, subject to certain potential acceleration set
forth below. If the Merger has not been consummated on or before September 30,
1994, then $1,000,000 of the indebtedness shall be automatically converted into
877,193 shares of Series D Preferred Stock of the Company at $1.14 per share,
on terms and conditions and subject to rights, preferences and privileges
substantially identical to the outstanding Series C Preferred Stock of the
Company (with no other series or class of stock of the Company having greater
preferences or priorities), and the $1,500,000 portion shall be treated as
purchase of a perpetual royalty-free non-exclusive non-transferable (which
provision shall be applicable only to significant source code) license (the
"License") to the Company's Reveal and Control Flow Front End products on terms
set forth in the License Agreement attached hereto as Exhibit 3 (collectively,
the "Conversion"); provided, however, that such Conversion shall not
automatically occur in the event of failure of the Merger to close as a result
of a material breach of a representation or warranty by the Company or
consideration of a competing offer by the Company in exercising its fiduciary
responsibilities (the "Fiduciary Duty Exemption") as contemplated in Section 10
of the Letter of Intent, in which case the Conversion shall be at Parent's
election. In the event Parent elects not to convert after an exercise by the
Company of its Fiduciary Duty Exemption, the repayment date of the indebtedness
shall be accelerated to the date of closing of the sale of the Company to a
third party acquiror. In the event of a Conversion, the Company will provide
reasonable assistance in transferring the related technology to Parent and
Parent will reimburse the Company at its fully burdened cost plus 10%.

5.12 Board Recommendation. Subject to applicable law and
applicable fiduciary duties, the Company's board of directors will recommend
the approval of the Merger and the transactions contemplated hereby to the
Company's shareholders.

5.13 Investment Representation Letters. Prior to the Closing, the
Company shall use its reasonable efforts to obtain investment representation
letters from holders of Company Preferred Stock (other than holders of
Dissenting Shares), in each case in form and substance reasonably satisfactory
to Parent (collectively, the "Investment Representation Letters"), which shall
include, at Parent's option, acknowledgement that any claims of such
shareholder against the Company have been disclosed therein. The parties agree
that should Parent suffer actual out-of-pocket damages as a result of the fact
that all of the Investment Representation Letters are not obtained prior to the
Effective Time, such damages shall constitute "Losses" for the purposes of
Article VII hereof. Parent agrees to sign a similar Investment Representation
Letter prior to any issuance of Series D Preferred of the Company to Parent
pursuant to Section 5.11.

-24-
<PAGE> 31

5.14 Employment Agreements. On or before the Effective Time,
Parent, Merger Sub, the Surviving Corporation or any combination of these, and
individuals to be identified by Parent shall enter into agreements pertaining
to prior and future employment and related issues (the "Employment Agreements")
in form and substance acceptable to Parent, which shall become effective as of
the Effective Time.

ARTICLE VII
SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ESCROW

7.1 Survival of Representations and Warranties. All covenants to
be performed prior to the Effective Time, representations and warranties in
this Agreement or in any instrument delivered pursuant to this Agreement shall
survive the Merger and continue, absent fraud, until the termination of the
Escrow Fund, as defined in paragraph 7.2(a) below.

7.2 Escrow Arrangements.

(a) Escrow Fund. As soon as practicable after the
Effective Time, a portion of the shares of the Parent Common Stock to be issued
in the Merger equal to the Escrow Number (as defined in paragraph 1.6(g)(iv))
(plus any additional New Shares (as defined below) as may be issued in respect
thereof after the Closing) (collectively, the "Escrow Shares"), without any act
of any shareholder, will be registered in

-27-

<PAGE> 34
the name of Escro & Co as nominee, and will be deposited with Bank of America
N.T. & S.A. Global Escrow Depository Services, (or other institution acceptable
to Parent and the Agent (as defined in Section 7.2(h) below)) as Escrow Agent
(the "Escrow Agent"), such deposit to constitute an escrow fund (the "Escrow
Fund") to be governed by the terms set forth herein and at the Surviving
Corporation's sole initial cost and expense, subject to the provisions of
paragraph (l) below. Each shareholder of the Company which receives Parent
Common Stock in the Merger shall contribute that number of shares of Parent
Common Stock to the Escrow Fund equal to the same percentage of the Escrow Fund
as that shareholder's percentage of the Aggregate Share Number received in the
Merger. The Escrow Fund shall be available to compensate Parent for any claim,
loss, expense, liability or other damage, including reasonable attorneys' fees
(including, without limitation, those set forth in Section 7.2(g)(iii), net of
insurance proceeds realized by Parent, to the extent of the amount of the
foregoing that Parent has incurred or reasonably anticipates incurring by
reason of the breach by the Company of any representation, warranty, covenant
or agreement of the Company contained herein, or by reason of any
misrepresentation by the Company made in or pursuant to Article II of this
Agreement (collectively, "Losses"); Parent and the Company each acknowledge
that the existence of such Losses at the Effective Time would have led to a
reduction in the total number of shares of Parent Common Stock Parent would
have agreed to issue in connection with the Merger. Resort to the Escrow Fund
shall be the exclusive contractual remedy of Parent and its affiliates for any
such breaches and misrepresentations if the Merger does close; provided,
however, that nothing herein shall limit any noncontractual remedy for fraud.
In consideration of the foregoing limitation of liability, Parent and the
Company agree that Parent's maximum liability, except for fraud, for any breach
of this Agreement shall likewise be limited to $1,000,000. Moreover, any claim
based on this Agreement or the transactions contemplated thereby must be filed
not later than 360 days after the date of Closing. In addition,
notwithstanding the foregoing, Parent may not receive any Escrow Shares from
the Escrow Fund unless and until Officer's Certificates (as defined in
paragraph (e) below) identifying Losses, the aggregate amount of which exceed
$25,000, have been delivered to the Escrow Agent as provided in paragraph (e);
in such case Parent may recover from the Escrow Fund the total of its Losses,
including the first $25,000. Nothing herein shall limit the liability of the
Company or the Parent for any breach of this Agreement if the Merger does not
close.

(b) Escrow Period; Distribution upon Termination of
Escrow Periods. Subject to the following requirements, the Escrow Fund shall
remain in existence during the following periods of time (the "Escrow
Periods"), beginning at the Effective Time. At the expiration of twelve (12)
months following the Effective Time, the Escrow Period shall terminate with
respect to all Escrow Shares; provided, however, that the number of Escrow
Shares, which, in the reasonable judgment of Parent, subject to the objection
of the Agent and the subsequent arbitration of the matter in the manner
provided in Section 7.2(g) hereof, are necessary to satisfy any Losses
specified in any Officer's Certificate theretofore delivered to the Escrow
Agent prior to termination of the twelve (12) month period with respect to
facts and circumstances existing prior to the termination of such twelve (12)
month period, shall remain in the Escrow Fund (and the Escrow Fund shall remain
in existence) until Parent's claims have been resolved. As soon as all such
claims have been resolved, the Escrow Agent shall deliver to the shareholders
of the Company all Parent Common Stock and other property remaining in the
Escrow Fund and not required to satisfy such claims. Deliveries of Parent
Common Stock and other property to the shareholders of the Company pursuant to
this Section 7.2(b) shall be made in proportion to their respective original
contributions to the Escrow Fund.

(c) Protection of Escrow Fund. The Escrow Agent shall
hold and safeguard the Escrow Fund during the Escrow Period, shall treat such
fund as a trust fund in accordance with the terms of this

-28-

<PAGE> 35
Agreement and not as the property of Parent and shall hold and dispose of the
Escrow Fund only in accordance with the terms hereof.

(d) Distributions; Voting.

(i) Any shares of Parent Common Stock or other
equity securities issued or distributed by Parent (including shares issued upon
a stock split) ("New Shares") in respect of Parent Common Stock in the Escrow
Fund which have not been released from the Escrow Fund shall be added to the
Escrow Fund and become a part thereof. New Shares issued in respect of Parent
Common Stock which have been released from the Escrow Fund shall not be added
to the Escrow Fund, but shall be distributed to the holders thereof. When and
if cash dividends on Parent Common Stock in the Escrow Fund shall be declared
and paid, they shall be added to the Escrow Fund.

(ii) Each shareholder of the Company shall have
voting rights with respect to the shares of Parent Common Stock contributed to
the Escrow Fund on behalf of such shareholder (and on any voting securities
added to the Escrow Fund in respect of such shares of Parent Common Stock) so
long as such shares of Parent Common Stock or other voting securities are held
in the Escrow Fund.

(e) Claims Upon Escrow Fund.

(i) Upon receipt by the Escrow Agent from time to
time on or before the last day of the Escrow Period of a certificate signed by
any officer of Parent (an "Officer's Certificate"):

(A) stating that Parent has paid or
properly accrued or reasonably anticipates that it will have to pay or accrue
Losses, and

(B) specifying in reasonable detail the
individual items of Losses included in the amount so stated, the date each such
item was paid or properly accrued, or the basis for such anticipated liability,
and the nature of the misrepresentation, breach of warranty or covenant or
claim to which such item is related,

the Escrow Agent shall, subject to the provisions of Section 7.2(f) hereof,
deliver to Parent out of the Escrow Fund, as promptly as practicable, shares of
Parent Common Stock or other assets held in the Escrow Fund in an amount equal
to such Losses.

(ii) For the purposes of determining the number of
shares of Parent Common Stock to be delivered to Parent out of the Escrow Fund
pursuant to Section 7.2(e)(i), the shares of Parent Common Stock shall be
valued at the Ten-Day Average Price, subject to appropriate adjustment for
stock splits, stock dividends, recapitalizations and the like.

(f) Objections to Claims. At the time of delivery of any
Officer's Certificate to the Escrow Agent, a duplicate copy of such certificate
shall be delivered to the Agent (as defined in Section 7.2(h)) and for a period
of thirty (30) days after such delivery, the Escrow Agent shall make no
delivery to Parent of shares of Parent Common Stock, pursuant to Section 7.2(e)
hereof unless the Escrow Agent shall have received written authorization from
the Agent to make such delivery. After the expiration of such thirty (30) day
period, the Escrow Agent shall make delivery of the shares of Parent Common
Stock or other property in the Escrow Fund in accordance with Section 7.2(e)
hereof, provided that no portion of such

-29-

<PAGE> 36
payment may be made if the Agent shall object to such portion of the claim made
in the Officer's Certificate in a written statement signed by the Agent (an
"Agent's Certificate"), and such Agent's Certificate shall have been delivered
to the Escrow Agent prior to the expiration of such thirty (30) day period.

(g) Resolution of Conflicts; Arbitration.

(i) In case the Agent shall so deliver an Agent's
Certificate, the Agent and Parent shall attempt in good faith to agree upon the
rights of the respective parties with respect to each of Parent's claimed
Losses. If the Agent and Parent should so agree, a memorandum setting forth
such agreement shall be prepared and signed by both parties and shall be
furnished to the Escrow Agent. The Escrow Agent shall be entitled to rely on
any such memorandum and distribute shares of Parent Common Stock or other
property from the Escrow Fund in accordance with the terms thereof.

(ii) If no such agreement can be reached after
good faith negotiation, either Parent or the Agent may demand arbitration of
the matter unless the amount of the damage or loss is at issue in pending
litigation with a third party, in which event arbitration shall not be
commenced until such amount is ascertained or both parties agree to
arbitration; and in either such event the matter shall be settled by
arbitration conducted by three arbitrators. Parent and the Agent shall each
select one arbitrator, and the two arbitrators so selected shall select a third
arbitrator. The arbitrators shall set a limited time period and establish
procedures designed to minimize the cost and time for discovery while allowing
the parties an opportunity, adequate in the sole judgement of the arbitrators,
to discover material relevant information from the opposing parties about the
subject matter of the dispute. The arbitrators shall rule upon motions to
compel or limit discovery and shall have the authority to impose sanctions,
including attorneys fees and costs, to the extent as would a court of competent
law or equity, should the arbitrators determine that discovery was sought
without substantial justification or that discovery was refused or objected to
without substantial justification. The decision of a majority of the three
arbitrators as to the validity and amount of any claim in such Officer's
Certificate shall be binding and conclusive upon the parties to this Agreement,
and notwithstanding anything in Section 7.2(f) hereof, the Escrow Agent shall
be entitled to act in accordance with such decision and make or withhold
payments out of the Escrow Fund in accordance therewith. Such decision shall
be written and shall be supported by written findings of fact and conclusions
which shall set forth the award, judgment, decree or order awarded by the
arbitrators.

(iii) Judgment upon any award rendered by the
arbitrators may be entered in any court having jurisdiction. Any such
arbitration shall be held in Santa Clara County, California, under the rules
then in effect of the American Arbitration Association. For purposes of this
Section 7.2(g), in any arbitration hereunder in which any claim or the amount
thereof stated in the Officer's Certificate is at issue, Parent shall be deemed
to be the Nonprevailing Party in the event that the arbitrators award Parent
less than the sum of one-half (1/2) of the disputed amount plus any amounts not
in dispute; otherwise, the Agent, on behalf of the shareholders of the Company,
shall be deemed to be the Nonprevailing Party. The Nonprevailing Party to an
arbitration shall pay its own expenses, the fees of each arbitrator, the
administrative fee of the American Arbitration Association, and the expenses,
including without limitation, reasonable attorneys' fees and costs, incurred by
the other party to the arbitration.

-30-
<PAGE> 37
(h) Agent of the Shareholders; Power of Attorney.

(i) In the event that the Merger is approved,
effective upon such vote, and without further act of any shareholder, Irwin
Federman shall be appointed as agent and attorney-in-fact (the "Agent") for
each shareholder of the Company (except such shareholders, if any, as shall
have perfected their dissenters' rights under California law and who shall not
be entitled to any rights in the Escrow Fund), for and on behalf of
shareholders of the Company, to give and receive notices and communications, to
authorize delivery to Parent of Parent Common Stock or other property from the
Escrow Fund in satisfaction of claims by Parent, to object to such deliveries,
to agree to, negotiate, enter into settlements and compromises of, and demand
arbitration and comply with orders of courts and awards of arbitrators with
respect to such claims, and to take all actions necessary or appropriate in the
judgment of Agent for the accomplishment of the foregoing. In the event the
Agent resigns from such appointment, the holders of a majority of the
outstanding Parent Common Stock issued in the Merger shall name a successor
Agent, who agrees to be bound by the provisions of Article VII and IX. In
addition, the Agent may be replaced by the shareholders of the Company from
time to time upon not less than thirty (30) days prior written notice to
Parent; provided that the Agent may not be removed unless holders of a
two-thirds interest of the Escrow Fund agree to such removal and to the
identity of the substituted agent. No bond shall be required of the Agent, and
the Agent shall not receive compensation for his or her services. Notices or
communications to or from the Agent shall constitute notice to or from each of
the shareholders of the Company.

(ii) The Agent shall not be liable to the
shareholders of the Company for any act done or omitted hereunder as Agent
while acting in good faith and in the exercise of reasonable judgment. The
shareholders of the Company on whose behalf shares of Parent Common Stock were
contributed to the Escrow Fund shall severally indemnify the Agent and hold the
Agent harmless against any loss, liability or expense incurred without
negligence or bad faith on the part of the Agent and arising out of or in
connection with the acceptance or administration of the Agent's duties
hereunder, including the reasonable fees and expenses of any legal counsel
retained by the Agent.

(i) Actions of the Agent. A decision, act, consent or
instruction of the Agent shall constitute a decision of all the shareholders
for whom shares of Parent Common Stock otherwise issuable to them are deposited
in the Escrow Fund and shall be final, binding and conclusive upon each of such
shareholders, and the Escrow Agent, the Surviving Corporation and Parent may
rely upon any such decision, act, consent or instruction of the Agent as being
the decision, act, consent or instruction of each and every such shareholder of
the Company. The Escrow Agent, the Surviving Corporation and Parent are hereby
relieved from any liability to any person for any acts done by them in
accordance with such decision, act, consent or instruction of the Agent.

(j) Third-Party Claims. In the event Parent becomes
aware of a third-party claim which Parent believes may result in a demand
against the Escrow Fund, Parent shall notify the Agent of such claim, and the
Agent, on behalf of and for the benefit of the shareholders of the Company,
shall be entitled (through the Agent), at their expense, to participate in any
defense of such claim. Parent shall have the right in its sole discretion to
settle any such claim; provided, however, that except with the consent of the
Agent, no settlement of any such claim with third-party claimants shall be
determinative of the validity of any claim against the Escrow Fund. In the
event that the Agent has consented to any such settlement, the Agent shall have
no power or authority to object under any provision of this Article VII to the
amount ofany claim by Parent against the Escrow Fund with respect to such
settlement.

-31-

<PAGE> 38
(k) Escrow Agent's Duties.

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

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

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

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

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

(l) Costs of Escrow. The first $5,000 of costs and
expenses relating to the establishment and maintenance of the Escrow Fund shall
be borne solely by the Surviving Corporation. The Surviving Corporation shall
be entitled to reimbursement for the next $5,000 of such costs and expenses out
of the Escrow Fund and the Agent shall have no authority to object to payment
from the Escrow Fund by the Escrow Agent to the Surviving Corporation in
respect of such reimbursement. To the extent that such costs and expenses
exceed $10,000, the Surviving Corporation shall solely bear one-half of such
excess costs and expenses and shall be entitled to reimbursement for the other
half of such excess costs and expenses from the Escrow Fund (it being
understood that the Agent shall have no authority to object to such
reimbursement).

-32-

<PAGE> 39
Without limiting the foregoing, the parties do not currently anticipate that
such costs and expenses will exceed $5,000.

ARTICLE VIII
TERMINATION, AMENDMENT AND WAIVER

8.1 Termination. This Agreement may be terminated and the Merger
abandoned at any time prior to the Effective Time:

(a) by mutual consent of the Company and Parent;

(b) by Parent if it is not in material breach of its
obligations under this Agreement and there has been a material breach of any
representation, warranty, covenant or agreement contained in this Agreement on
the part of the Company and such breach has not been cured within fifteen (15)
days after notice to the Company.

(c) by the Company if it is not in material breach of its
respective obligations under this Agreement and there has been a material
breach of any representation, warranty, covenant or agreement contained in this
Agreement on the part of Parent or Merger Sub and such breach has not been
cured within fifteen (15) days after notice to Parent;

(d) by any party hereto if: (i) the Closing has not
occurred by September 30, 1994; (ii) there shall be a final nonappealable order
of a federal or state court in effect preventing consummation of the Merger;
(iii) there shall be any action taken, or any statute, rule, regulation or
order enacted, promulgated or issued or deemed applicable to the Merger by any
Governmental Entity which would make consummation of the Merger illegal; or
(iv) there shall be any action taken, or any statute, rule, regulation or order
enacted, promulgated or issued or deemed applicable to the Merger by any
Governmental Entity, which would (A) prohibit Parent's or the Surviving
Corporation's ownership or operation of all or a material portion of the
business of the Surviving Corporation, or compel Parent or the Surviving
Corporation to dispose of or hold separate all or a material portion of the
business or assets of the Surviving Corporation or Parent as a result of the
Merger or (B) render Parent, Merger Sub or the Company unable to consummate the
Merger, except for any waiting period provisions.

Where action is taken to terminate this Agreement pursuant to
this Section 8.1, it shall be sufficient for such action to be authorized by
the Board of Directors (as applicable) of the party taking such action.

8.2 Effect of Termination. In the event of termination of this
Agreement as provided in Section 8.1, this Agreement shall forthwith become
void and there shall be no liability or obligation on the part of Parent,
Merger Sub or the Company or their respective officers, directors or
shareholders, except if such termination results from the breach by a party
hereto of any of its representations, warranties, covenants or agreements set
forth in this Agreement (it being understood that termination of this Agreement
because of failure of the Company to satisfy the condition set forth in
Section 6.3(a) as a result of the occurrence of a Post-Execution Event shall
not be deemed to be a termination resulting from such a breach of
representation or warranty; it being further understood that termination of
this Agreement because of failure of Parent to satisfy the condition set forth
in Section 6.2(a) as a result of the occurrence of an event occurring subsequent

-33-

<PAGE> 40
to the date of execution of this Agreement that would render any representation
or warranty made by Parent in this Agreement untrue if such representation or
warranty were made as of the Effective Time, shall not be deemed to be a
termination resulting from a breach by Parent of its representations or
warranties.) Notwithstanding the foregoing, if the Merger fails to close for
any reason, Parent's $2.5 million loan to Company (described in Section 5.11)
shall automatically convert into 877,193 shares of Series D Preferred Stock of
the Company (reflecting the conversion of $1,000,000 at $1.14 per share), with
rights, preferences and privileges equal to those of the Series C Preferred
stock, and the balance into a license in the form set forth in Exhibit 3,
unless the failure to close is as a result of a material breach of
representation or warranty by the Company or because of a competing offer for
the Company contrary to Section 5.11, in which case the conversions will be at
Parent's election. If the conversion is effected, then neither party shall
have any further obligation to the other except as set forth in the form of
license and form of escrow agreements.

8.3 Amendment. This Agreement may be amended by the parties
hereto at any time before or after approval of matters presented in connection
with the Merger by the shareholders of those parties required by applicable law
to so approve but, after any such shareholder approval, no amendment shall be
made which by law requires the further approval of shareholders of a party
without obtaining such further approval. This Agreement may not be amended
except by an instrument in writing signed on behalf of each of the parties
hereto.

8.4 Extension; Waiver. At any time prior to the Effective Time
any party hereto may, to the extent legally allowed, (i) extend the time for
the performance of any of the obligations or other acts of the other parties
hereto, (ii) waive any inaccuracies in the representations and warranties made
to such party contained herein or in any document delivered pursuant hereto and
(iii) waive compliance with any of the agreements or conditions for the benefit
of such party contained herein. Any agreement on the part of a 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.

<PAGE> 6

(c) Exchange Procedures. Promptly after the Effective
Time, the Surviving Corporation shall cause to be mailed to each holder of
record of a certificate or certificates which immediately prior to the
Effective Time represented outstanding shares of Company Preferred Stock whose
shares were converted into the right to receive shares of Parent Common Stock
pursuant to Section 1.6 (the "Certificates"), (i) a letter of transmittal
(which shall specify that delivery shall be effected, and risk of loss and
title to the Certificates shall pass, only upon delivery of the Certificates to
the Exchange Agent and shall be in such form and have such other provisions as
Parent may reasonably specify) and (ii) instructions for use in effecting the
surrender of the Certificates in exchange for certificates representing shares
of Parent Common Stock. Upon surrender of a Certificate for cancellation to
the Exchange Agent or to such other agent or agents as may be appointed by
Parent, together with such letter of transmittal, duly completed and validly
executed in accordance with the instructions thereto, the holder of such
Certificate shall be entitled to receive in exchange therefor a certificate
representing the number of whole shares of Parent Common Stock (less the number
of shares of Parent Common Stock, if any, to be deposited in the Escrow Fund
on such holder's behalf pursuant to Article VII of the Reorganization
Agreement) to which such holder is entitled pursuant to Section 1.6, and the
Certificate so surrendered shall forthwith be canceled. As soon as practicable
after the Effective Time, and subject to and in accordance with the provisions
of Article VII of the Reorganization Agreement, Parent shall cause to be
distributed to the Escrow Agent (as defined in Article VII of the
Reorganization Agreement) a certificate or certificates representing that
number of shares of Parent Common Stock equal to the Escrow Number which shall
be registered in the name of the Escrow Agent. Such shares shall be
beneficially owned by the holders on whose behalf such shares were deposited in
the Escrow Fund and shall be available to compensate Parent as provided in
Article VII of the Reorganization Agreement. Until so surrendered, each
outstanding Certificate that, prior to the Effective Time, represented shares
of Company Preferred Stock will be deemed from and after the Effective Time,
for all corporate purposes, other than the payment of dividends, to evidence
the ownership of the number of full shares of Parent Common Stock into which
such shares of Company Preferred Stock shall have been so converted in
accordance with Section 1.6 and subject to the limitations of Article VII of
the Reorganization Agreement.

(d) Distributions With Respect to Unexchanged Shares. No
dividends or other distributions declared or made after the Effective Time with
respect to Parent Common Stock with a record date after the Effective Time will
be paid to the holder of any unsurrendered Certificate with respect to the
shares of Parent Common Stock represented thereby until the holder of record of
such Certificate shall surrender such Certificate. Subject to applicable law,
following surrender of any such Certificate, there shall be paid to the record
holder of the certificates representing whole shares of Parent Common Stock
issued in exchange therefor, without interest, at the time of such surrender,
the amount of dividends or other distributions with a record date after the
Effective Time theretofore paid with respect to such whole shares of Parent
Common Stock.

<PAGE> 7

(f) No Liability. Notwithstanding anything to the
contrary in this Section 1.8, none of the Exchange Agent, the Surviving
Corporation, the Escrow Agent, the Agent (as defined in Article VII of the
Reorganization Agreement), the Company, Parent or Merger Sub or any party
hereto shall be liable to a holder of shares of Parent Common Stock, Company
Preferred Stock or Company Common Stock for any amount properly paid to a
public official pursuant to any applicable abandoned property, escheat or
similar law.

ARTICLE II
TERMINATION, AMENDMENT AND WAIVER

2.1 Termination. This Agreement may be terminated and the Merger
abandoned at any time prior to the Effective Time:

(a) by mutual consent of the Company and Parent;

(b) by Parent if it is not in material breach of its
obligations under the Reorganization Agreement and there has been a material

Reorganization Agreement on the part of the Company and such breach has not
been cured within fifteen (15) days after notice to the Company.

Agreement prior to the Effective Time as provided in Section 2.1, this
Agreement shall forthwith become void and there shall be no liability or
obligation on the part of Parent, Merger Sub or the Company or their respective
officers, directors or shareholders, except as set forth in the Reorganization
Agreement.

2.3 Amendment. This Agreement may be amended by the parties
hereto at any time before or after approval of matters presented in connection
with the Merger by the shareholders of those parties required by applicable law
to so approve but, after any such shareholder approval, no amendment shall be
made which by law requires the further approval of shareholders of a party
without obtaining such further approval. This Agreement may not be amended
except by an instrument in writing signed on behalf of each of the parties
hereto.

2.4 Extension; Waiver. At any time prior to the Effective Time
any party hereto may, to the extent legally allowed, (i) extend the time for
the performance of any of the obligations or other acts of the other parties
hereto, (ii) waive any inaccuracies in the representations and warranties made
to such party contained herein or in any document delivered pursuant hereto and

of such party contained herein. Any agreement on the part of a party hereto to

in writing signed on behalf of such party.
