    THE COMPANY'S BOARD OF DIRECTORS HAS DETERMINED THAT THE MERGER IS FAIR AND

                                PROXY STATEMENT
                      FOR SPECIAL MEETING OF STOCKHOLDERS
                                 JUNE 30, 2000

    This Proxy Statement (the "Proxy Statement") is being furnished to the
holders of Common Stock, par value $0.10 per share ("Common Stock"), of
GateField Corporation, a Delaware corporation (the "Company"), in connection
with the solicitation of proxies by the Board of Directors of the Company for
use at a special meeting of stockholders (the "Special Meeting") of the Company
to be held on Friday, June 30, 2000 at 8:00 a.m., local time, and any
adjournments thereof, at the Company's principal executive office located at
47436 Fremont Boulevard, Fremont, California 94538-6503 for the following
purpose:

    To approve and adopt an Amended and Restated Agreement and Plan of Merger
    dated May 31, 2000 by and among the Company, Actel Corporation, a California
    corporation and a principal stockholder of the Company ("Actel"), GateField
    Acquisition Corporation, a Delaware corporation and a wholly-owned
    subsidiary of Actel (the "Merger Sub") and with respect to Section 5.17
    thereof only, Idanta Partners Ltd., a Texas general partnership ("Idanta")
    (the "Merger Agreement") and to approve the merger (the "Merger") of the
    Company and the Merger Sub as described therein.

    The proposed merger is described in detail in the accompanying Proxy
Statement and its annexes. Please read all of these materials carefully.

    The Merger Agreement provides for the merger of the Merger Sub with and into
the Company with the Company continuing as the surviving corporation and
wholly-owned subsidiary of Actel. Subject to the terms and conditions of the
Merger Agreement, each share of Common Stock of the Company outstanding as of
the Effective Date (as defined below) will be converted into and become a right
to receive $5.25 per share in cash, without interest, all as more fully
described in the Proxy Statement.

    Approval and adoption of the Merger Agreement requires the affirmative vote
of a majority of the outstanding shares of the Company's Common Stock held by
stockholders of record on May 25, 2000 (the "Record Date"). Pursuant to the
terms of the Merger Agreement, Actel, Idanta, and certain affiliates of Idanta
have agreed to vote shares owned by them in favor of the approval and the
adoption of the Merger Agreement and the Merger. As of the Record Date, Idanta
and its affiliates owned 507,318 shares of the Company's Common Stock,
representing approximately 8.4% of the shares of Common Stock outstanding, and
Actel owned 1,621,298 shares of the Company's Common Stock, representing
approximately 26.4% of the shares of Common Stock outstanding.

    The Board of Directors has fixed the close of business on May 25, 2000 as
the record date for the determination of stockholders entitled to notice of and
to vote at the Special Meeting and at any adjournment or postponement thereof.

    THE MERGER IS FOR CASH ONLY. AFTER THE CLOSING OF THE MERGER, CURRENT
COMPANY STOCKHOLDERS WILL HAVE NO FURTHER OWNERSHIP INTEREST IN THE COMPANY.

    This Proxy Statement, the accompanying form of proxy (the "Proxy") and the
other enclosed documents are first being mailed to the stockholders of the
Company on or about [June 10, 2000].

              The date of this Proxy Statement is [June 10, 2000].

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q: WHEN AND WHERE IS THE STOCKHOLDER MEETING?

A: The meeting will take place on Friday, June 30, 2000, in Fremont, California.
The exact location for the meeting can be found on page 19. The meeting may be
postponed if there are not enough votes to approve the merger.

Q: WHAT DO I NEED TO DO NOW?

A: After carefully reading and considering the information contained in this
document, the attachments to this documents, and the documents referred to in
this document, please fill out, sign and mail your signed proxy card in the
enclosed return envelope as soon as possible so that we may vote your shares at
the special meeting of our stockholders.

In order to assure that we obtain your vote, please give your proxy as
instructed on your proxy card, even if you currently plan to attend the meeting
in person.

Q: WHAT IF I DON'T INDICATE HOW TO VOTE MY PROXY?

A: If you do not include instructions on how to vote your properly signed proxy,
your shares will be voted FOR adoption of the merger agreement and approval of
the merger.

Q: WHAT IF I DON'T RETURN A PROXY CARD?

A: Not returning your proxy card will have the same effect as voting against the
merger.

Q: CAN I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD?

A: Yes. You can change your vote at any time before your proxy is voted at the
special meeting. You can do this in one of three ways. First, you can send a
written notice to our Secretary stating that you would like to revoke your
proxy. Second, you can complete and submit a new proxy card. Third, you can
attend the special meeting, file a written notice of revocation of your proxy
with our Secretary and vote in person. Your attendance alone will not revoke
your proxy.

Q: IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
SHARES FOR ME?

A: No. Your broker will not be able to vote your shares without instructions
from you. If you do not provide your broker with instructions on how to vote,
your shares will be considered present at the special meeting for purposes of
determining a quorum, but will not be considered to have been voted in favor of
adoption of the merger agreement and will have the same effect as voting against
the merger. If you have instructed a broker to vote your shares, you must follow
directions received from your broker to change those instructions.

Q: WHAT WILL I RECEIVE IN THE MERGER?

A: If the merger is completed, you will receive $5.25, in cash, without
interest, for each share of our common stock that you own.

Q: WHEN CAN I EXPECT THE MERGER TO BE COMPLETE?

A: We are working toward completing the merger as quickly as possible. We hope
to complete the merger on June 30, 2000.

Q: SHOULD I SEND IN MY STOCK CERTIFICATES NOW?

A: No. After the merger is completed, Actel and/ or its exchange agent will send
you written instructions for surrendering your stock certificate for cash.

Q: WILL I RECOGNIZE A GAIN OR LOSS ON THE TRANSACTION?

A: In general, you will recognize gain or loss for federal income tax purposes
equal to the difference, if any, between the cash you receive as a result of the
merger (or pursuant to your dissenter's rights under Delaware or California law)
and the adjusted tax basis for your common stock. Generally, such gain or loss
will be capital gain or loss if you have held your shares for more than one year
as of the effective date of the merger. Please see "CERTAIN FEDERAL INCOME TAX
CONSEQUENCES" beginning on page 18 for further details on this issue.

                                       3
<PAGE>
You should consult with your tax adviser concerning your particular situation,
including any state and foreign laws that might affect you, as a result of the
merger.

Q: AM I ENTITLED TO DISSENTERS' RIGHTS OF APPRAISAL?

A: Yes. You have the right to dissent from the merger under both Delaware and
California law and to receive payment of the fair market value of your shares of
GateField common stock. Please see "APPRAISAL RIGHTS OF DISSENTING STOCKHOLDERS"
beginning on page 39 and Annexes III and IV for further details on this issue.

Q: WHO CAN HELP ANSWER MY QUESTIONS?

A: You can write or call our Corporate Secretary, Lynne M. Bennett, at GateField
Corporation, 47436 Fremont Boulevard, Fremont, California 94538-6503, telephone
(510) 623-4400, fax (510) 623-4484, email [email protected] with any

                                    SUMMARY

    THIS SUMMARY HIGHLIGHTS SELECTED INFORMATION FROM THIS DOCUMENT AND MAY NOT
CONTAIN ALL OF THE INFORMATION THAT IS IMPORTANT TO YOU. TO UNDERSTAND THE
MERGER MORE FULLY AND FOR A MORE COMPLETE DESCRIPTION OF THE LEGAL TERMS OF THE
MERGER, YOU SHOULD CAREFULLY READ THIS DOCUMENT, THE MERGER AGREEMENT, THE
OPINION OF NEEDHAM & COMPANY, INC., SECTION 262 OF THE DELAWARE GENERAL
CORPORATION LAW, AND SECTIONS 1300-1312 OF THE CALIFORNIA GENERAL CORPORATION
LAW, COPIES OF WHICH ARE ATTACHED AS ANNEXES I, II, III AND IV.

THE COMPANIES

    GATEFIELD CORPORATION

    GateField designs, develops and markets high-density, high performance
programmable logic solutions and related development software.

    GateField's principal executive offices are located at 47436 Fremont
Boulevard, Fremont, California 94538-6503, and its telephone number is
(510) 623-4400. For additional information relating to GateField's business,
operations, properties and other matters, see "THE COMPANY."

    ACTEL CORPORATION

    Actel designs, develops and markets field programmable gate array devices
that are used in communications, computer, consumer and internet-appliance,
industrial, military/aerospace and other electronic systems.

    Actel's principal executive offices are located at 955 East Arques Avenue,
Sunnyvale, California 94086-4533, and its telephone number is (408) 739-1010.
For additional information relating to Actel's business, operations, properties
and other matters, see "INFORMATION CONCERNING ACTEL AND MERGER SUB--ACTEL."

PRINCIPAL REASONS FOR THE MERGER (SEE PAGE 12)

    We estimate that we will exhaust all of our currently available capital
resources on or about June 30, 2000. If the merger does not occur and we were
unable to obtain additional financing, the Company will be unable to continue as
a going concern. The merger, if consummated, will give you some return on your
investment in GateField and will remove the risk of losing all of your
investment if GateField were unable to continue as a going concern.

    We believe that, if the merger is not consummated, we will need to raise
between $6 and $10 million to meet our capital requirements through the end of
2000 and a similar amount to meet our capital requirements through the end of
2001. After exploring various funding alternatives, we do not believe we would
be able to raise the reqired funding.

    We believe that Actel is the best potential purchaser of GateField. We
believe that Actel's exclusive worldwide right to market and sell our ProASIC
products makes us less attractive to other potential purchasers. In addition,
Actel's ownership of 26.4% of our common stock would enable it to significantly
influence the stockholder vote on any other potential acquisition.

RECOMMENDATION TO STOCKHOLDERS (SEE PAGE 12)

    Our board of directors unanimously believes that the merger is fair to you
and in your best interests and recommends that you vote FOR approval and
adoption of the merger and the merger agreement.

OPINION OF FINANCIAL ADVISOR (SEE PAGE 14)

    Our financial advisor, Needham & Company, Inc. delivered an opinion to our
board of directors on May 23, 2000 that, as of the date of such opinion, the per
share consideration to be paid in the merger was fair, from a financial point of
view, to the holders of our common stock. The complete Needham & Company, Inc.
opinion is attached as ANNEX II and you are urged to read it in its entirety.

THE MERGER (SEE PAGE 21)

    Under the terms of the merger agreement, a wholly-owned subsidiary of Actel,
formed for the purpose of the merger, will merge with and into GateField with
GateField being the surviving corporation. As a result of the merger, we will
become a direct, wholly-owned subsidiary of Actel.

    The merger agreement is attached as ANNEX I to this document. We encourage
you to read the merger agreement as it is the legal document that governs the
merger.

                                       5
<PAGE>
WHAT GATEFIELD STOCKHOLDERS WILL RECEIVE (SEE PAGE 21)

    The merger agreement provides that at the effective time of the merger, each
issued and outstanding share of our common stock will be canceled and converted
into the right to receive $5.25 in cash, without interest.

STOCKHOLDER VOTE REQUIRED TO APPROVE THE MERGER (SEE PAGE 20)

    The affirmative vote of holders of a majority of the shares of common stock
outstanding and entitled to vote on the record date of May 25, 2000 is required
to approve the merger agreement.

    On the record date of May 25, 2000, Actel owned approximately 26.4% of our
common stock and Idanta Partners Ltd. and its affiliates owned approximately
8.4% of our common stock. Actel, Idanta and certain affiliates of Idanta have
agreed to vote their shares in favor of the approval of the merger and adoption
of the merger agreement.

    You are entitled to cast one vote per share of GateField common stock you
owned at the close of business on May 25, 2000, the record date.

    You should mail your signed proxy card in the enclosed return envelope as
soon as possible so that your shares of GateField common stock may be
represented at the special meeting. If you do not include instructions on how to
vote your properly executed proxy, your shares will be voted FOR adoption and
approval of the merger and the merger agreement.

    If your shares are held in street name, your broker will vote your shares
only if you provide instructions on how to vote by following the information
provided to you by your broker. IF YOU DO NOT PROVIDE YOUR BROKER WITH VOTING
INSTRUCTIONS, YOUR SHARES WILL NOT BE VOTED AT THE GATEFIELD SPECIAL MEETING,
WHICH WILL HAVE THE SAME EFFECT AS VOTING AGAINST THE APPROVAL AND ADOPTION OF
THE MERGER AND THE MERGER AGREEMENT.

    If you desire to change your vote, just send a written notice to our
Secretary stating that you would like to revoke your proxy, or deliver to the
Secretary of GateField a later-dated, signed proxy card, before the special
meeting, or attend the special meeting in person, revoke your proxy there and
vote in person.

DISSENTERS' RIGHTS OF APPRAISAL (SEE PAGE 39)
    Under Section 262 of the Delaware General Corporation Law and Sections
1300-1312 of the California General Corporation Law, you and other GateField
stockholders will have the right to dissent from the merger. Stockholders who
dissent from the merger and otherwise comply with the provisions of Delaware or
California law will be entitled to receive fair market value of their shares as
determined in accordance with applicable law.

INTERESTS OF UNAFFILIATED STOCKHOLDERS (SEE PAGE 14)

    The merger and the merger agreement must be approved by the holders of a
majority of our common stock outstanding on the record date. Because Actel owns
26.4% of our common stock it will significantly influence the outcome of the
stockholder vote. The approval of a majority of our stockholders other than
Actel is NOT required.

INTERESTS OF CERTAIN PERSONS (SEE PAGE 34)

    When considering our board's recommendation that you vote in favor of the
merger, you should be aware that some of GateField's directors and officers may
have interests in the merger that are different from or in addition to yours.

    In connection with the merger, the interests of the directors and executive
officers of GateField relate to the assumption of our stock options held by them
into options to purchase Actel common stock. In addition and subject to
consummation of the merger, Timothy Saxe, our Chief Executive Officer, will
accept a Vice President position with Actel, with salary and benefits
commensurate with current standards for a person with comparable technological
expertise and executive experience. See "THE MERGER AGREEMENT--STOCK OPTIONS,"
"THE MERGER AGREEMENT--INDEMNIFICATION; INSURANCE" AND "INTERESTS OF CERTAIN
PERSONS IN THE MERGER."

CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER (SEE PAGE 18)

    In general, each stockholder will recognize gain or loss for federal income
tax purposes equal to the difference, if any, between the cash received

                                       6
<PAGE>
pursuant to the merger (or the exercise of dissenters' rights) and such
stockholder's adjusted tax basis for its common stock. In general, such gain or
loss will be capital gain or loss if the stockholder has held its common stock
for more than one year as of the effective date of the merger. Such transactions
may also be taxable under applicable state, local and foreign tax laws and may
be subject to backup withholding. You and all other stockholders are urged to
consult your own tax advisors. See "THE MERGER--CERTAIN FEDERAL INCOME TAX
CONSEQUENCES."

CONDITIONS TO COMPLETION OF THE MERGER (SEE PAGE 24)

    The completion of the merger is subject to a number of conditions, including
the following:

    - approval and adoption of the merger agreement by our stockholders;

    - absence of any law prohibiting the merger; and

    - receipt of authorizations, consents or approvals needed to consummate the
      merger.

    The completion of the merger is not subject to governmental review under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976.

TERMINATION OF THE MERGER AGREEMENT (SEE PAGE 25)

    Either GateField or Actel can terminate the merger agreement if any of the
following occur:

    - we do not complete the merger within 60 days after the mailing of this
      proxy statement; or

    - a law or court order permanently prohibits the merger.

    We may terminate the merger agreement if any of the following occurs:

    - we receive an offer that is superior to the terms of the merger with
      Actel; or

    - Actel breaches any condition, representation or warranty contained in the
      merger agreement;

    Actel may terminate the merger agreement if any of the following occurs:

    - the stockholders of GateField do not approve the merger within 50 days
      after the mailing of this proxy statement;

    - our board recommends an acquisition proposal by another party;

    - our board modifies or withdraw its recommendation in favor of the merger
      in a manner adverse to Actel;

    - we breach any condition, representation or warranty contained in the
      merger agreement; or

    - by written notice to us.

EFFECT OF TERMINATION (SEE PAGE 25)

    If Actel terminates the agreement because of a breach of any condition,
representation or warranty in the merger agreement by us or because stockholder
approval is not obtained, Actel may choose to purchase a $3 million promissory
note that is convertible into our common stock at the rate of $5.25 per share.

    If we terminate the agreement because of a breach of any condition,
representation or warranty in the merger agreement by Actel or if Actel
terminates the agreement without cause, we may require Actel to purchase a
$3 million promissory note that is convertible into our common stock at the rate
of $5.25 per share.

PAYMENT OF MERGER CONSIDERATION AND SURRENDER OF SHARES (SEE PAGE 22)

    The closing and effectiveness of the merger will occur after the conditions
to closing have been satisfied or waived.

    Actel will appoint an exchange agent to handle the payment for the GateField
shares. IF YOU HAVE CERTIFICATES REPRESENTING GATEFIELD SHARES, PLEASE DO NOT
SEND THEM TO US NOW. THE EXCHANGE AGENT SELECTED BY ACTEL WILL CONTACT YOU WITH
INSTRUCTIONS FOR THE SURRENDER OF YOUR CERTIFICATES.

                                SPECIAL FACTORS

PAST CONTACTS BETWEEN GATEFIELD AND ACTEL

1998 STRATEGIC ALLIANCE

    In August 1998, the Company entered into a multi-year strategic alliance
with Actel. In establishing the alliance, Actel purchased certain marketing and
license rights, shares of the Company's Series C Preferred Stock, and the assets
of the Company's Design Services Business Unit. Consideration paid in these
transactions totaled $10.5 million, consisting entirely of cash. Since the
establishment of this strategic alliance, the Company and Actel have been in
constant contact.

    PRODUCT MARKETING AGREEMENT

    Under the terms of a Product Marketing Agreement dated as of August 14,
1998, Actel received exclusive, worldwide distribution rights to the Company's
standard application specific integrated circuit technology ("ProASIC") and
flash technology-based, high-density field programmable gate array ("FPGA")
products with process geometries of less than 0.35-micron, including FPGA
products that are integrated with SRAM or flash memory and all resulting next
generation reduced process geometry ProASIC FPGA products. For these rights,
Actel paid the Company an initial fee of $1.0 million and agreed to pay a $1.0
million fee upon qualification of the initial 0.25-micron product. In addition,
Actel and the Company will split equally the gross margins from ProASIC product
sales. The Company's recognition of the $1.0 million initial fee has been
deferred until delivery to Actel of pre-production quality parts with process
geometries of less than 0.35-micron.

    Under the terms of the Product Marketing Agreement, development of the
underlying technology and products is managed and executed primarily by the
Company. The Agreement contains certain milestones relating to the development
schedule and manufacturing costs of the 0.25-micron product family. If the
Company fails to achieve such cost milestones, it must notify Actel and seek its
consent to corrective action. The Company has so notified Actel and the two
companies are jointly working on corrective measures. The Product Marketing
Agreement also contains Actel milestones with respect to the marketing and sale
of the 0.25-micron products (including certain revenue targets). The delays in
meeting GateField's milestones under the Product Marketing Agreement relieve
Actel from meeting the marketing and sales milestones.

    LICENSE AGREEMENT

    Pursuant to the terms of a License Agreement dated as of August 14, 1998,
the Company granted to Actel a fully paid, non-exclusive, non-transferable
license to sell and, upon certain conditions, to make, have made, import, and
use the Company's standard ProASIC FPGA products with process geometries of less
than 0.35-micron and all resulting next-generation reduced process geometry
ProASIC FPGA products. For these rights, Actel paid the Company a license fee of
$1 million. The Company's recognition of the $1 million license fee received as
revenue has been deferred until delivery to Actel of pre-production quality
parts with process geometries of less than 0.35-micron.

    PREFERRED STOCK PURCHASE AGREEMENT

    Pursuant to terms of a Series C Preferred Stock Purchase Agreement dated as
of August 14, 1998, the Company issued 300,000 shares of Series C Convertible
Preferred Stock, par value $0.10 (the "Series C Preferred"), to Actel for an
aggregate purchase price of $3.0 million. Each share of Series C Preferred was
entitled to certain preferential liquidation rights and was convertible into
6.67 shares of Common Stock plus an amount of shares at the conversion price
equal to the amount of accrued and unpaid dividends on the Series C Preferred.
In the event all shares of the Company's Series B Preferred Stock ("Series B
Preferred") were redeemed, each share of Series C Preferred was subject to
redemption at a price of

                                       8
<PAGE>
$10.00 per share plus the amount of declared but unpaid dividends. In addition,
Actel was entitled to certain registration rights and had a right of first
refusal to purchase its pro rata share of certain new securities that the
Company issued. Pursuant to the terms of the Merger Agreement, Actel converted
the Series C Preferred into 200,000 shares of Common Stock on May 24, 2000.

    ASSET PURCHASE AGREEMENT

    Pursuant to the terms of an Asset Purchase Agreement dated as of August 14,
1998, Actel purchased from the Company the assets of its Design Services
Business Unit, which is located in Mt. Arlington, New Jersey, and engaged in the
business of providing prototyping design services and verification services for
electronic systems, integrated circuits and other electronic components. The
purchase price for such assets was (i) $5.4 million plus (ii) contingent
payments payable over a three-year period on a quarterly basis based on Design
Services achieving certain profitability levels, which payments may not exceed
$1.0 million in the aggregate.

1999 COMMON STOCK FINANCING

    Under the Series C Preferred Stock Purchase Agreement between Actel and the
Company, Actel had a right of first refusal to purchase its pro rata share of
certain new securities the Company may wish to sell. On September 30, 1999, the
Company sold, and two subsidiaries of Mitsui High-tec Inc. (Mitsui Create USA,
Inc. and MHT American Holdings, Inc.) purchased, a total of 307,696 shares of
Company Common Stock at $6.50 per share, for an aggregate sales price of $2.0
million. The owners of the Company's Series B Preferred Stock, Idanta and
certain affiliates of Idanta, exercised their rights to participate on a
pro-rata basis and purchased a total of 52,035 shares of Company Common Stock
for $338,223.44. Actel also exercised its right to participate on a pro-rata
basis and purchased 112,129 shares of Company Common Stock for $728,829.75. The
purchase of Company Common Stock by Actel was effected pursuant to a Common
Stock Purchase Agreement between Actel and Company dated as of September 30,
1999.

1999 AND 2000 CONVERTIBLE PROMISSORY NOTE FINANCINGS

    In May 1999, the Company issued and sold to Actel a convertible promissory
note in the aggregate principal amount of $8 million (the "Convertible
Promissory Note"). The Convertible Promissory Note accrued interest at the rate
of 5.22% per annum, had a five-year term, and was secured by a lien against all
the assets of the Company. Interest under the Convertible Promissory Note was
payable quarterly from the date of issuance. The Convertible Promissory Note was
convertible at Actel's election into 420,000 shares of Series C-1 Convertible
Preferred Stock (the "Series C-1 Preferred"), which was in turn convertible into
1,230,769 shares of Common Stock, equating to a price of $6.50 per share of
Common Stock. Pursuant to the terms of the Merger Agreement, Actel converted the
Convertible Promissory Note into 420,000 shares of Series C-1 Preferred, and
converted the Series C-1 Preferred into 1,230,769 shares of Common Stock, on
May 24, 2000.

    Under the terms of the Security Agreement dated May 25, 1999, pursuant to
which the Convertible Promissory Note was secured, the Company could request
Actel to make an additional loan to the Company on the same terms and conditions
as the Convertible Promissory Note and, if Actel declined to make such
additional loan, Actel agreed to execute a subordination agreement in favor of
any third party lender for a loan of up to $4 million in aggregate principal
amount. On May 23, 2000, the Company requested Actel to make an additional loan
of $4 million to the Company on the same terms as the Convertible Promissory
Note. On May 24, 2000, Actel declined to make the loan, but offered to make a
loan of $3.0 million to the Company on the same terms as the Convertible
Promissory Note, except that such new loan would be convertible into the
Company's Common Stock at an effective rate of $5.25 (rather than $6.50) per
share. The Company accepted Actel's offer and, on May 31, 2000, the Company and
Actel entered into a Security Agreement granting Actel a lien against all of the
Company's assets, the Company executed and delivered a 6.25% Convertible Note
Due 2005 in the principal amount of $1.0

                                       9
<PAGE>
million, and Actel loaned $1.0 million to the Company. The new convertible
promissory note is convertible at Actel's election into 35,000 shares of
Series C-2 Convertible Preferred Stock (the "Series C-2 Preferred"), which are
in turn convertible into 190,476 shares of Common Stock.

BACKGROUND OF THE MERGER

    In July 1998, the Company approached Actel about a possible merger or
financing. Actel was not interested in a merger at that time, and the strategic
alliance between the companies was structured to permit each to remain
independent, but the Company and Actel have always recognized that the strategic
alliance might lead to a merger of the two companies. Since the establishment of
the strategic alliance in August 1998, the question of whether the Company and
Actel should merge has been raised often in a wide range of forums, but it was
not until March 2000 that any such inquiry received a positive response from the
other company or led to any negotiations.

    On March 7, 2000, Timothy Saxe, the Company's President & CEO, telephoned
John East, Actel's President & CEO, to schedule a telephonic discussion between
Mr. East and Jonathan Huberman, Chairman of the Company's Board of Directors,
regarding a potential business combination between the Company and Actel. The
telephonic discussion occurred March 15, 2000, when Mr. Huberman indicated to
Mr. East that the Company was interested in being acquired by Actel and wished
to begin negotiations immediately.

    On March 21, 2000, Messrs. Huberman and Saxe met with Dennis Kish, Actel's
Vice President of Strategic Marketing, Fares Mubarak, Actel's Vice President of
Engineering, and David Van De Hey, Actel's Vice President & General Counsel.
Mr. Huberman indicated that the Company was interested in being acquired by
Actel because the Company had determined that it was no longer viable as a
stand-alone entity, that it was going to lose employees if nothing were done,
and that resources were being wasted managing the relationship between the two
companies. The Actel representatives indicated that Actel believed an
acquisition would permit the ProASIC technology to be brought to market faster
and aid in the retention of the Company's employees, but that the Company's
ongoing operating losses were a potentially insurmountable financial problem.
With respect to price, the Company's representatives indicated that $10.00 per
share was too low, while the Actel representatives indicated that $7 per share
was too high.

    On March 30, 2000, Messrs. Huberman and Saxe again met with Messrs. Kish,
Mubarak, and Van De Hey. At the conclusion of the meeting, the Company and Actel
agreed to consider a three-tiered price structure for an acquisition in which
the price would be $10.75 per share if the Company achieved certain technical
milestones, $9.00 per share if the Company achieved certain lesser milestones,
and $7.25 per share if the Company did not achieve either set of milestones.

    Over the next three weeks, while milestones and organizational issues were
being negotiated, there were two significant developments. First, the Company
recognized new technological problems with products under development, which
caused Actel to indicate that it would pay no more than $4 per share if the
Company did not achieve either set of milestones. Second, the Company
experienced an increase in employee retention issues. This increased the desire
of both the Company and Actel to complete the Merger as quickly as possible.

    On April 20, 2000, James Boyd, the Company's Chief Financial Officer, and
Mr. Van De Hey met with outside legal counsel for the Company and Actel to
discuss the three-tiered pricing structure. As a result of this meeting, the
Company and Actel both concluded that a fixed-price structure would permit the
acquisition to be completed in a more timely manner. Actel also advised the
Company that Actel believed it bore all of the risk in the three-tiered pricing
structure, since the price would have been fixed by the time the Company's
stockholders were asked to approve the acquisition.

                                       10
<PAGE>
    On April 21, 2000, Actel advised the Company that Actel's Board of Directors
had authorized management to continue its discussions with the Company but did
not approve the three-tiered price structure.

    On May 2, 2000, Messrs. Huberman and Saxe met with Messrs. Kish, Mubarak,
and Van De Hey. At the conclusion of the meeting, the Company and Actel agreed
that the acquisition should proceed at a fixed price, and that the price should
be negotiated following a thorough technical review. The Company and Actel
conducted joint technical reviews on May 5 and 6, 2000, and each company
conducted an internal technical debriefing on May 8, 2000.

    On the evening of May 8, 2000, Mr. Saxe met with Messrs. Mubarak and Van De
Hey with Mr. Huberman participating by telephone. At the conclusion of the
meeting, the Actel representatives indicated that Actel would be interested in
acquiring the Company for cash at a price of $5.25 per share, and the Company's
representatives indicated that it was essential for Actel to be unconditionally
committed to either consummate any proposed merger or provide additional
financing. Continued negotiations over the next two days led to an agreement
that Actel would loan the Company, at the Company's election, $3 million on the
same terms as the Convertible Promissory Note (except that the new loan would be
convertible into Common Stock at the rate of $5.25 per share) if Actel chose not
to consummate the proposed merger (the "Call Option").

    On May 11, 2000, the Company and Actel executed and delivered a nonbinding
letter of intent to merge. At 4:21 p.m., Eastern Time, on May 11, 2000, the
Company and Actel issued a joint press release announcing the proposed merger.
At approximately the same time, Mr. Saxe informed the Company's employees of the
proposed merger, and representatives from Actel's Human Resources Department met
individually with the Company's employees to discuss the implications of the
proposed merger.

    Between May 10 and May 24, 2000, senior management of the Company and Actel
and their respective legal counsel held extensive negotiations regarding the
terms and conditions of the agreements relating to the proposed merger. On
May 16, 2000, Needham & Company, Inc. ("Needham") was retained by the Company as
financial advisor relating to the proposed merger.

    On May 16, 2000, Mr. Saxe of the Company and Mr. East of Actel met with
Franz Neppl of Infineon, the Company's wafer fabrication partner, to discuss the
proposed merger of the Company and Actel. The meeting was requested by Actel in
order to ascertain whether Infineon would continue to support the Company's
ProASIC products following the proposed merger. Actel advised the Company it was
satisfied with the results of such meeting.

    On May 23, 2000, the Company's Board of Directors met with its legal and
financial advisors to discuss the final terms of the proposed merger. Needham
reviewed its financial analysis of the proposed transaction, answered questions
posed by the Company's Board of Directors and delivered an oral opinion,
subsequently confirmed in writing, that, as of such date and based upon the
procedures followed, factors considered and assumptions made by Needham, and
subject to the limitations set forth in its written opinion, the consideration
to be received by the holders of the Common Stock other than Actel and its
affiliates in the Merger was fair to such holders from a financial point of
view. At the conclusion of these discussions and presentation, the Company's
Board of Directors voted to approve the Merger Agreement and set the Record
Date.

    On May 24, 2000, the Company, Actel, Idanta, and Merger Sub entered into an
Agreement and Plan of Merger. Immediately following the execution and delivery
of such agreement, Idanta converted its shares of Series B Preferred into Common
Stock, and Actel converted its Convertible Promissory Note into shares of Series
C-1 Preferred and converted its shares of Series C Preferred and Series C-1
Preferred into Common Stock, as required by the Merger Agreement. The Merger
Agreement also requires Idanta, certain affiliates of Idanta and Actel to vote
all of their shares of Common Stock for approval of the Merger, which in
aggregate amount to approximately 34.8% of the shares of common stock
outstanding.

                                       11
<PAGE>
    The Company's Board of Directors also concluded at its meeting on May 23,
2000, that the Company would probably exhaust all of its cash resources before
the contemplated closing of the Merger on June 30, 2000. Mr. Saxe was directed
by the Company's Board of Directors to make a formal request on behalf of the
Company that Actel make an additional loan of $4.0 million to the Company on the
same terms as the Convertible Promissory Note. Mr. Saxe made such request on
May 23, 2000. On May 24, 2000, Actel informed the Company that Actel was
unwilling to make an additional loan on the terms requested. On May 25, 2000,
the Company and Actel agreed that Actel would make a loan of $1.0 million to the
Company on the same terms as the Convertible Promissory Note except that such
new loan would be convertible into the Company's Common Stock at an effective
rate of $5.25 per share.

    On May 31, 2000, Actel, Idanta and Merger Sub amended and restated the
Agreement and Plan of Merger signed on May 24. This amendment and restatement
added the Call Option and a provision under which Actel can, under certain
circumstance and at its election, require the Company to borrow $3.0 million on
the same terms as the Call Option (the "Put Option"). Also, on May 31, 2000, the
Company and Actel entered into a Security Agreement, the Company executed and
delivered a 6.25% Convertible Note Due 2005 in the principal amount of $1.0
million, and Actel loaned $1.0 million to the Company. As with the original
Convertible Promissory Note between the parties, all assets of the Company are
pledged to secure this loan. The 6.25% Convertible Note Due 2005 is convertible
at Actel's election into 35,000 shares of Series C-2 Preferred, which are in
turn convertible into 190,476 shares of Common Stock.

    On [June __, 2000], Actel made an offer of employment to Mr. Saxe, the
effectiveness of which is subject to the consummation of the Merger. To date,
the principal terms of such employment agreement have not been finalized.

REASONS FOR THE MERGER; RECOMMENDATION OF THE BOARD OF DIRECTORS

    The Board of Directors of the Company has determined that the Merger is fair
and in the best interests of the Company and its stockholders and has
unanimously approved the Merger Agreement and the transactions contemplated
thereby, including the Merger. THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS
THAT THE COMPANY'S STOCKHOLDERS VOTE "FOR" THE MERGER AGREEMENT AND THE MERGER.

    In determining to recommend that the Company's stockholders vote FOR the
Merger Proposal, the Board considered a number of factors, including the
following:

    (i)  THE ABILITY OF THE COMPANY TO CONTINUE AS A GOING CONCERN AND
COMMERCIALIZE IN THE NEAR TERM THE COMPANY'S 0.25-MICRON PRODUCTS AND RELATED
SOFTWARE.  During the first quarter ended March 31, 2000 and the year ended
December 31, 1999 the Company incurred net losses of approximately $1.3 million
and $10.0 million, respectively. The Company estimates it will have exhausted
all of its currently available capital resources on or about June 30, 2000.
Furthermore, the Company is highly dependent upon the successful introduction of
its 0.25-micron generation products. The Company is currently completing testing
of its 0.25-micron products and related software. Even though the Company began
testing its 0.25-micron products in November 1998, the results have not yet
yielded production parts. Initially the tests showed large lot-to-lot variations
in yield and reliability. Many, or perhaps all, of these problems have been
resolved, however testing is not completed and there is no way of knowing that
more problems will not show up in the future. Although yield has improved, it
has not improved as rapidly as planned and there is still uncertainty as to how
stable yield is and when it will reach commercially acceptable levels. If and
until yield reaches planned levels, costs will be higher than planned and
consequently the Company will consume cash faster than expected. At the same
time, delays in getting production parts resulted in delays in marketing the
products and consequently delays in revenue from product sales. During this
delay, the Company's competitors continued to improve their product features and
process technology, which reduced the attractiveness and hence commercial value
of the Company's product. At this time the Company's competitors are launching
competitive products in 0.18-micron geometries, which reduce the attractiveness
of the Company's products and its ability to win much needed design wins.

                                       12
<PAGE>
    (ii)  THE COMPANY'S CURRENT FINANCIAL CONDITION AND THE AVAILABILITY OF
FUTURE FUNDING.  In the past, the Company has explored a number of potential
sources of additional capital. The Company currently anticipates that capital in
the aggregate principal amount of $6.0 million to $10.0 million would meet its
capital requirements through 2000 and up to an additional $9.0 million would be
needed through 2001. In 1999, the Company contacted a number of alternative
financing sources, all of whom declined to provide funding to the Company. Prior
to entering into negotiations with Actel, the Company reviewed with Needham the
likelihood of obtaining additional funding from sources other than Actel. It was
concluded that the Company would not be any more successful in obtaining funding
than in 1999. The Company did have informal discussions with three other
companies about the possibility of either an investment or an acquisition. These
discussions did not result in any offers.

   (iii)  THE PROBLEM OF RETAINING AND RECRUITING KEY PERSONNEL.  On
December 31, 1999, the Company had 33 total employees and 19 research and
development related employees. On April 30, 2000 the Company had 29 total
employees and 18 research and development related employees. In May 2000, the
Company lost 2 research and development employees or 11% of its research and
development workforce and was concerned about losing more research and
development employees due to the financial condition of the Company. The
uncertainty surrounding the Company's future makes it difficult for the Company
to attract and retain qualified replacements.

    (iv)  THE BOARD OF DIRECTOR'S VIEW, AFTER CONSULTATION WITH MANAGEMENT,
REGARDING THE LIKELIHOOD OF THE EXISTENCE OF OTHER VIABLE PURCHASERS.  The Board
of Directors considered the possibility that other companies might be willing to
acquire the Company. As discussed above, informal discussions with three
potential acquirers did not lead to any offers. The Board of Directors believed
that the Company's strategic alliance with Actel, which gives Actel exclusive
distribution rights to the Company's most valuable products, significantly
reduces the Company's attractiveness to potential acquirers. In addition, the
Board believes that most likely potential acquirers of the Company would be
other producers of FPGA's and, therefore, direct or indirect competitors of
Actel. As Actel owns 26.4% of the Company, it can exercise significant influence
on shareholder matters. The Board believed that it was likely that Actel would
use that influence to oppose any proposed sale of the Company to a competitor.
Taking these factors together, the Board concluded that it was highly unlikely
that there was any other potential acquirer of the Company which would be
willing to pay a higher price for the Company than Actel.

    (v)  THE OPINION OF NEEDHAM DELIVERED TO THE BOARD ON MAY 23, 2000 TO THE
EFFECT THAT, AS OF THE DATE OF SUCH OPINION, THE CONSIDERATION TO BE PAID TO
HOLDERS OF COMMON STOCK (OTHER THAN ACTEL AND ITS AFFILIATES) IN THE MERGER (THE
"MERGER CONSIDERATION") WAS FAIR, FROM A FINANCIAL POINT OF VIEW, TO THOSE
HOLDERS.  The full text of the written opinion is attached hereto as ANNEX II
and should be read carefully in its entirety. SEE "OPINION OF FINANCIAL ADVISOR"
BELOW.

    (vi)  THE AVAILABILITY OF APPRAISAL RIGHTS UNDER DELAWARE AND CALIFORNIA LAW
FOR DISSENTING STOCKHOLDERS. Appraisal rights would allow any stockholder who
believed that the $5.25 Merger Consideration was insufficient to seek an
opportunity to so assert under Delaware and California law. See "APPRAISAL
RIGHTS OF DISSENTING STOCKHOLDERS" BELOW.

   (vii)  THE TERMS AND CONDITIONS OF THE MERGER AGREEMENT ALLOW THE COMPANY TO
ACCEPT A PROPOSAL THAT IS SUPERIOR TO THE MERGER PROPOSAL OF ACTEL.  The members
of the Board of Directors noted that the Merger Agreement provides that the
Company may terminate the Merger Agreement and accept an alternative acquisition
proposal if the Board determines in good faith, based upon the opinion of its
outside financial advisors, such proposal to be more favorable to the Company's
stockholders than the Merger. Despite the provisions in the Merger Agreement
which allow the Company to respond to unsolicited third party offers, no such
third party offer has been forthcoming in the three weeks that the proposed
Merger has been publicly known.

  (viii)  THE COVENANT BY IDANTA, THE HOLDER OF A MAJORITY OF THE SERIES B
PREFERRED, TO CONVERT ALL OF SUCH SHARES INTO COMMON STOCK PRIOR TO THE RECORD
DATE AND TO VOTE ALL SHARES OF COMMON STOCK OVER WHICH IT OR

                                       13
<PAGE>
ANY OF ITS GENERAL PARTNERS HAVE VOTING AND INVESTMENT POWER IN FAVOR OF THE
MERGER.  The Board of Directors also took into consideration that Idanta agreed
to support the Merger and forego its liquidation rights and preferences that
would be available upon consummation of the Merger.

    (ix)  THE RECOMMENDATION OF THE COMPANY'S MANAGEMENT IN FAVOR OF THE MERGER.

    (x)  THE FAIRNESS OF THE MERGER CONSIDERATION OF $5.25 PER SHARE OF COMMON
STOCK.  The Board of Directors was mindful of the fact that an all cash offer of
$5.25 provided certainty of value to the stockholders in contrast to the
speculative nature of a continuing interest in the Company. The Merger, if
consummated, would give the stockholders some return on their investment and
remove the risk of losing all of their investment if the Company is unable to
continue as a going concern. Among other things, the Board of Directors
considered the continuing declining price performance and low trading volume of
the Common Stock.

    (xi)  THE POTENTIAL CONFLICT OF INTEREST OF ANY DIRECTOR OR EXECUTIVE
OFFICER OF THE COMPANY WITH RESPECT TO THE MERGER BY REASON OF SUCH DIRECTOR'S
OR EXECUTIVE OFFICER'S STOCK OWNERSHIP, EMPLOYMENT ARRANGEMENTS, STOCK OPTIONS
OR STOCKHOLDER VOTING AGREEMENTS.

    The foregoing discussion of the information and factors considered by the
Board of Directors is not meant to be exhaustive but includes all material
factors considered by it. The Board of Directors did not believe there were any
material negative factors inherent in the Merger when compared to the
alternatives available to the Company. In view of the variety of factors
considered, the Board of Directors did not find it practical to, and did not,
quantify or otherwise attempt to assign relative weights to the specific factors
considered in reaching its determination.

INTERESTS OF UNAFFILIATED STOCKHOLDERS

    The affirmative vote of the holders of a majority of the outstanding shares
of the Company is required for approval of the Merger and the Merger Agreement.
As Actel owns approximately 26.4% of the outstanding shares of the Company, it
will significantly influence the results of the stockholder vote. The
transaction has not been structured so as to require the affirmative vote of the
holders of the majority of the outstanding shares excluding Actel's shares.

    The Merger and the Merger Agreement were unanimously approved by the
Company's Board of Directors including the two members of the Board of Directors
who are not employees of the Company. The non-employee directors did not retain
a separate representative to act solely on behalf of the stockholders other than
Actel in connection with the negotiation of the Merger.

OPINION OF FINANCIAL ADVISOR

    The Company retained Needham to render an opinion as to the fairness, from a
financial point of view, of the consideration to be paid in the proposed merger
to the holders of Common Stock (other than Actel and its affiliates). The amount
of consideration to be paid in the merger was determined through arm's length
negotiations between the Company and Actel and not by Needham.

    At a meeting of the Company's Board of Directors on May 23, 2000, Needham
delivered its oral opinion, which it subsequently confirmed in writing, that, as
of that date and based upon and subject to the assumptions and other matters
described in the written Needham opinion, the proposed merger consideration is
fair to the holders of Common Stock (other than Actel and its affiliates) from a
financial point of view. THE NEEDHAM OPINION IS ADDRESSED TO THE COMPANY'S
BOARD, IS DIRECTED ONLY TO THE FINANCIAL TERMS OF THE MERGER AGREEMENT, AND DOES
NOT CONSTITUTE A RECOMMENDATION TO ANY STOCKHOLDER AS TO HOW THAT STOCKHOLDER
SHOULD VOTE AT THE SPECIAL MEETING.

                                       14

    The complete text of the Needham opinion, which sets forth the assumptions
made, matters considered, limitations on and scope of the review undertaken by
Needham, is attached to this document as ANNEX II, and the summary of the
Needham opinion set forth in this Proxy Statement is qualified in its entirety
by reference to the Needham opinion. STOCKHOLDERS ARE URGED TO READ THE NEEDHAM
OPINION CAREFULLY AND IN ITS ENTIRETY FOR A DESCRIPTION OF THE PROCEDURES
FOLLOWED, THE FACTORS CONSIDERED, AND THE ASSUMPTIONS MADE BY NEEDHAM.

    In arriving at its opinion, Needham, among other things:

    - reviewed a draft of the Merger Agreement dated May 12, 2000;

    - reviewed selected publicly available information concerning the Company
      and selected other relevant financial and operating data of the Company
      furnished to it by the Company;

    - held discussions with members of the Company's management concerning
      current and future business prospects;

    - reviewed and discussed with the Company's management various financial
      forecasts and projections prepared by management;

    - reviewed the historical stock prices and trading volumes of the Company's
      Common Stock;

    - compared publicly available financial data of companies whose securities
      are traded in the public markets and that Needham deemed generally
      relevant to similar data for the Company;

    - reviewed the financial terms of selected other business combinations that
      Needham deemed generally relevant; and

    - performed and/or considered such other studies, analyses, inquiries and
      investigations as Needham deemed appropriate.

    Needham also considered and discussed with the Company's management various
issues with respect to the Company's liquidity position, including management's
estimate that the Company would use all of its available capital resources by
June 30, 2000, its ability to continue as a going concern absent additional
financing, its ability to raise equity capital in the current market, and its
negative book value. Needham also noted that Actel owned over 25% of the Company
and considered the potential impact of that ownership stake on the Company's
ability to enter into financing or merger and acquisition transactions with
other parties.

    Needham assumed and relied upon, without independent verification, the
accuracy and completeness of the information reviewed by or discussed with it
for purposes of rendering its opinion, Needham assumed that the financial
forecasts provided to Needham by the Company's management were reasonably
prepared on bases reflecting the best currently available estimates and
judgments of management, at the time of preparation, of the Company's future
operating and financial performance. Needham did not assume any responsibility
for or make or obtain any independent evaluation, appraisal or physical
inspection of the assets or liabilities of the Company. The Needham opinion
states that it was based on economic, monetary and market conditions existing as
of its date. Needham expressed no opinion as to the prices at which the Common
Stock will trade at any time. In addition, Needham was not asked to consider,
and the Needham opinion does not address:

    - the Company's underlying business decision to engage in the merger,

    - the relative merits of the merger as compared to any alternative business
      strategies that might exist for the Company, or

    - the effect of any other transaction in which the Company might engage.

                                       15
<PAGE>
    No limitations were imposed by the Company on Needham with respect to the
investigations made or procedures followed by Needham in rendering its opinion.

    Based on this information, Needham performed a variety of financial analyses
of the merger and the merger consideration. The following paragraphs summarize
the material financial analyses performed by Needham in arriving at its opinion.

    SELECTED COMPANY ANALYSIS.  Using publicly available information, Needham
compared selected historical and projected financial and market data ratios for
the Company to the corresponding data and ratios of other publicly traded
semiconductor companies that Needham deemed relevant because their lines of
businesses are similar to the Company's line of business. These companies (the
"Selected Companies") consisted of:

<TABLE>

    Altera Corporation                         QuickLogic Corporation
    Xilinx, Inc.
</TABLE>

    The following table sets forth information, for the Selected Companies and
for the Company, concerning multiples of total market capitalization to last
twelve months' revenues ("LTM revenues"). Needham calculated multiples for the
Selected Companies based on the closing stock prices on May 22, 2000 and for the
Company based on the Merger Consideration of $5.25 per share of Common Stock.

</TABLE>

    Needham calculated the market value of Common Stock as a multiple of
earnings per share, or price/ earnings multiple, for the last twelve months, and
market value as a multiple of historical book value, but determined that the
results were not meaningful because of the Company's net losses for the last
twelve months and negative book value.

    Needham also calculated multiples and ratios for projected calendar 2000 and
2001 results, but placed substantially less emphasis on those multiples and
ratios, noting that the Company would likely not achieve those projected results
due to its liquidity concerns and due to its performance to date in 2000.

    SELECTED TRANSACTION ANALYSIS.  Needham also analyzed publicly available
financial information for 63 selected mergers and acquisitions of companies in
the semiconductor sector that represent transactions since January 1, 1990 (the
"Selected Transactions"). Needham also analyzed two subsets of the Selected
Transactions: 30 transactions with transaction values between $10 million and
$100 million and 12 transactions with transaction values between $25 million and
$50 million. In examining the Selected Transactions, Needham analyzed

    - the premium of consideration offered to the acquired company's stock price
      one day prior to the announcement of the transaction,

    - the premium of consideration offered to the acquired company's stock price
      four weeks prior to the announcement of the transaction and

    - the aggregate transaction value as a multiple of sales for the last twelve
      months ("LTM sales").

    Needham also analyzed, for the Selected Transactions,

    - the aggregate transaction value as a multiple of earnings before interest
      and taxes for the last twelve months,

                                       16
<PAGE>
    - the aggregate transaction value as a multiple of earnings before interest,
      taxes, depreciation and amortization for the last twelve months,

    - market value as a multiple of net income for the last twelve months and

    - market value as a multiple of historical book value,

but determined that the results were not meaningful because of the Company's net
losses for the last twelve months and negative book value. In some cases,
complete financial data was not publicly available for the Selected Transactions
and only partial information was used in those instances.

    The following table sets forth information concerning the stock price
premiums in the Selected Transactions and the stock price premiums implied by
the proposed merger. The premiums implied by the proposed merger were based on
the Merger Consideration of $5.25 per share of Common Stock.

    No company, transaction or business used in the "Selected Company Analysis"
or "Selected Transaction Analysis" as a comparison is identical to the Company,
Actel or the Merger. Accordingly, these analyses are not simply mathematical;
rather, they involve complex considerations and judgments concerning differences
in the financial and operating characteristics and other factors that could
affect the acquisition, public trading or other values of the Selected
Companies, Selected Transactions, or the business segment, company or
transaction to which they are being compared.

                                       17

    OTHER ANALYSES.  In rendering its opinion, Needham considered various other
analyses, including, among other things, a history of trading prices and volumes
for the Company, noting that the Common Stock has had low trading volumes, is
traded over-the-counter and is quoted on the OTC Bulletin Board.

    The summary set forth above does not purport to be a complete description of
the analyses performed by Needham in connection with the rendering of its
opinion. The preparation of a fairness opinion involves various determinations
as to the most appropriate and relevant quantitative and qualitative methods of
financial analyses and the application of those methods to the particular
circumstances and, therefore, such an opinion is not readily susceptible to
summary description. Accordingly, Needham believes that its analyses must be
considered as a whole and that considering any portions of its analyses and of
the factors considered, without considering all analyses and factors, could
create a misleading or incomplete view of the process underlying its opinion. In
its analyses, Needham made numerous assumptions with respect to industry
performance, general business and economic and other matters, many of which are
beyond the control of the Company or Actel. Any estimates contained in these
analyses are not necessarily indicative of actual values or predictive of future
results or values, which may be significantly more or less favorable.
Additionally, analyses relating to the values of business or assets do not
purport to be appraisals or necessarily reflect the prices at which businesses
or assets may actually be sold. Accordingly, these analyses and estimates are
inherently subject to substantial uncertainty. The Needham opinion and Needham's
related analyses were only one of many factors considered by the Company's Board
of Directors in its evaluation of the proposed merger and should not be viewed
as determinative of the views of the Board of Directors or management with
respect to the Merger Consideration or the Merger.

    Under the terms of Needham's engagement letter with the Company, the Company
has paid or agreed to pay Needham fees for rendering the Needham opinion that
the Company and Needham believe are customary in transactions of this nature.
None of Needham's fees are contingent on consummation of the Merger. The Company
has also agreed to reimburse Needham for its reasonable out-of-pocket expenses
and to indemnify it against specified liabilities relating to or arising out of
the rendering of the opinion or other services performed under the engagement
letter by Needham as financial advisor to the Company.

    Needham is a nationally recognized investment banking firm. As part of its
investment banking services, Needham is frequently engaged in the evaluation of
businesses and their securities in connection with mergers and acquisitions,
negotiated underwritings, secondary distributions of securities, private
placements and other purposes. Needham was retained by the Board of Directors to
act as the Company's financial advisor in connection with the merger based on
Needham's experience as a financial advisor in mergers and acquisitions as well
as Needham's familiarity with the semiconductor industry. Needham has had no
other investment banking relationship with the Company or Actel during the past
two years. In the normal course of its business, Needham may actively trade the
equity securities of the Company or Actel for its own account or for the account
of its customers and, therefore, may at any time hold a long or short position
in those securities.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

    The following is a general summary of the material federal income tax
consequences of the Merger to beneficial owners of Common Stock and to holders
of options to purchase Common Stock, and is based upon current provisions of the
Internal Revenue Code of 1986, as amended (the "Code"), existing, proposed,
temporary and final regulations thereunder and current administrative rulings
and court decisions, all of which are subject to change (possibly on a
retroactive basis). No attempt has been made to comment on all federal income
tax consequences of the Merger that may be relevant to particular holders,
including those that are subject to special tax rules such as dealers in
securities, mutual funds, insurance companies, tax-exempt entities, stockholders
who do not hold their Common Stock as capital assets and stockholders that, for
federal income tax purposes, are non-resident alien individuals, foreign
corporations, foreign partnerships or foreign estates or trusts.

                                       18
<PAGE>
    The tax discussion set forth below is included for general information only.
It is not intended to be, nor should it be construed to be, legal or tax advice
to any particular stockholder. Stockholders are advised and expected to consult
with their own legal and tax advisers regarding the federal income tax
consequences of the Merger under state, local and foreign tax laws.

    In general, each stockholder will recognize gain or loss for federal income
tax purposes equal to the difference, if any, between the cash received pursuant
to the Merger or pursuant to the exercise of dissenters' rights and such
stockholder's adjusted tax basis for its Common Stock. In general, such gain or
loss will be capital gain or loss if the stockholder has held its Common Stock
for more than one year as of the effective date of the Merger.

    Unless a stock holder entitled to receive cash payments pursuant to the
Merger complies with certain reporting and certification procedures, or
otherwise demonstrates to the satisfaction of the Exchange Agent under the
Merger Agreement that it is an exempt recipient under applicable withholding
provisions of the Code and the Treasury regulations promulgated thereunder, such
stockholder may be subject to federal backup withholding at a rate of 31% with
respect to all such cash payments which such stockholder is entitled to receive.
Backup withholding is not an additional tax. Rather, the tax liability of
persons subject to 31% backup withholding will be reduced by the amount of tax
withheld.

    Consummation of the Merger will result in a change of control under Internal
Revenue Code Section 382 limiting the future use of the Company's existing NOL
carry forwards.

                              THE SPECIAL MEETING

DATE, PLACE AND TIME

    The Special Meeting will be held at 8:00 a.m., local time, on Friday,
June 30, 2000 at the Company's principal executive office located at
47436 Fremont Boulevard, Fremont, California 94538-6503.

PURPOSE

    At the Special Meeting, the Company's stockholders will consider and vote
upon the Merger Agreement and the Merger.

    The Company's Board of Directors has determined that the Merger is fair and
in the best interests of the Company and its stockholders and has unanimously
approved the Merger Agreement and the Merger. THE BOARD OF DIRECTORS UNANIMOUSLY
RECOMMENDS THAT THE COMPANY'S STOCKHOLDERS VOTE "FOR" THE MERGER. SEE "REASONS
FOR THE MERGER; RECOMMENDATION OF THE BOARD OF DIRECTORS."

REVOCABILITY OF PROXIES

    Any person giving a proxy pursuant to this solicitation has the power to
revoke it at any time before it is voted. It may be revoked by filing with the
Secretary of the Company at the Company's principal executive office,
47436 Fremont Boulevard, Fremont, California 94538-6503, a written notice of
revocation or a duly executed proxy bearing a later date, or it may be revoked
by attending the Special Meeting and voting in person. Attendance at the Special
Meeting will not, by itself, revoke a proxy.

SOLICITATION OF PROXIES

    Proxies are being solicited hereby on behalf of the Board of Directors of
the Company. The Company will bear the entire cost of solicitation of proxies,
including preparation, assembly, printing and mailing of this proxy statement,
the accompanying proxy card and any additional information furnished to
stockholders. Copies of solicitation materials will be furnished to banks,
brokerage houses, fiduciaries and custodians holding in their names shares of
Common Stock beneficially owned by others to forward to such

                                       19
<PAGE>
beneficial owners. The Company may reimburse persons representing beneficial
owners of Common Stock for their costs of forwarding solicitation materials to
such beneficial owners. Original solicitation of proxies by mail may be
supplemented by telephone, telegram or personal solicitation by directors,
officers or other regular employees of the Company or, at the Company's request,
Beacon Hill Partners, Inc. No additional compensation will be paid to directors,
officers or other regular employees for such services, but Beacon Hill
Partners, Inc. would be paid reasonable out-of-pocket expenses, if it renders
solicitation services.

RECORD DATE AND VOTING RIGHTS

    Only stockholders of record at the close of business on the Record Date will
be entitled to notice of and to vote at the Special Meeting. On the close of
business on the day prior to the Record Date, the Company had outstanding and
entitled to vote 6,151,482 shares of Common Stock. Each holder of record of
Common Stock on such date will be entitled to one vote for each share held on
all matters to be voted upon.

    All votes will be tabulated by the inspector of election appointed for the
meeting, who will separately tabulate affirmative and negative votes,
abstentions and broker non-votes. Abstentions and broker non-votes are each
included in the determination of the number of shares present and voting, and
each is tabulated separately. However, broker non-votes are not counted for
purposes of determining the number of votes cast with respect to a particular
proposal.

QUORUM

    A majority of the outstanding shares of the Common Stock must be represented
in person or by proxy at the Special Meeting in order to constitute a quorum for
the transaction of business. Abstentions and broker non-votes are counted for
purposes of determining the presence or absence of a quorum for the transaction
of business. If a quorum is not present or represented at the Special Meeting,
the stockholders entitled to vote at the Special Meeting, whether in person or
represented by proxy, shall only have the power to adjourn the Special Meeting
for the purpose of allowing additional time for soliciting and obtaining
additional proxies or votes. The Special Meeting will be adjourned even if a
quorum is present if a sufficient proxies or votes approving the Merger have not
been received. At any subsequent reconvening of the Special Meeting, all proxies

original convening of the Special Meeting, except for any proxies which have
theretofore effectively been revoked or withdrawn. At such time as a quorum is
present or represented by proxy, the Special Meeting will reconvene without
notice to stockholders, other than an announcement at the prior adjournment of
the Special Meeting, unless the adjournment is for more than thirty days or a
new record date has been set.

REQUIRED VOTE

    Approval of the Merger Agreement and the Merger will require the affirmative
vote of the holders of a majority of shares of the Common Stock outstanding on
the Record Date.

                              THE MERGER AGREEMENT

    The description of the Merger Agreement contained in this Proxy Statement
discusses the material aspects thereof, but does not purport to be complete in
every respect. It is qualified in its entirety by reference to the Amended and
Restated Merger Agreement, a copy of which is attached hereto as ANNEX I and
incorporated herein by reference.

EFFECTIVE TIME

    As soon as is practicable after the satisfaction or waiver of the conditions
precedent to the Merger (as set forth below), a certificate of merger will be
filed with the Secretary of State of the State of Delaware. The Merger will
become effective at the time of acceptance of such filings with the Secretary of
State of Delaware (the "Effective Time"). On the same day as such filing with
the Secretary of State of Delaware a closing of the Merger will be held (the
"Closing"). The date of the Closing is hereinafter referred to as the Closing
Date.

THE MERGER

    At the Effective Time, the Merger Sub will be merged with and into the
Company, with the Company continuing as the surviving corporation (in such
capacity, the "Surviving Corporation") and wholly-owned subsidiary of Actel. As
a result of the Merger, the separate existence of the Merger Sub will cease and
all the rights and property of Merger Sub and the Company will vest in the
Surviving Corporation, and all debts and liabilities of Merger Sub and the
Company will become the debts and liabilities of the Surviving Corporation.

    At the Effective Time, the Certificate of Incorporation and the Bylaws of
the Merger Sub as in effect immediately prior thereto, will become the
Certificate of Incorporation and Bylaws, respectively, of the Surviving
Corporation, until thereafter amended in accordance with applicable law.

    The directors and officers of Merger Sub immediately prior to the Effective
Time will become the directors of the Surviving Corporation.

CONVERSION OF SECURITIES

    COMMON STOCK. At the Effective Time, by virtue of the Merger and without any
action on the part of any stockholder of the Company:

    (i) each issued and outstanding share of Common Stock (other than shares
held by dissenting stockholders, the Company, Actel or any of their
subsidiaries) shall be canceled and converted into and become a right to receive
the Merger Consideration of $5.25 in cash, without interest;

    (ii) each share of Common Stock held in the treasury of the Company, or
issued and outstanding and owned by Actel or any subsidiaries of the Company or
Actel will be canceled and retired without consideration; and

    (iii) each dissenting stockholder will be entitled to receive the "fair
market value" of such shares of Common Stock held by them in accordance with the
applicable provisions of Delaware Law or California Law. SEE "APPRAISAL RIGHTS
OF DISSENTING STOCKHOLDERS."

    Shares of Common Stock which immediately prior to the Effective Time are
held by person who have properly exercised and perfected appraisal rights under
either Section 262 of the DGCL or Section 1300-1312 of the CGCL (the "Dissenting
Shares") will not be converted into or represent the right to receive the Merger
Consideration. The holders of Dissenting Shares will be entitled to receive such
consideration as shall be determined pursuant to Section 262 of the DGCL or
Section 1300-1312 of the CGCL; provided, however, that if any such holder fails
to perfect or effectively withdraw or lose such holder's right to appraisal or
payment under the DGCL or CGCL, each of such holder's shares of

                                       21
<PAGE>
Common Stock will be deemed to have been converted as of the Effective Time into
the right to receive the applicable Merger Consideration, without any interest
thereon, and such shares will no longer be Dissenting Shares. Although
stockholders may perfect their appraisal rights under both the DGCL and the
CGCL, Actel and the Merger Sub will be obligated obligated, if at all, to make a
"fair market value" payment under only one of such remedies.

    After the Effective Time, holders of certificates to be exchanged for Merger
Consideration will cease to have rights with respect thereto, except the right
to surrender such certificates in exchange for payment of the Merger
Consideration or the right to perfect appraisal rights.

PAYMENT OF MERGER CONSIDERATION

    Prior to the Effective Time, Actel will designate the Exchange Agent under
the Merger Agreement. On or before the Effective Time, Actel will deposit with
the Exchange Agent, the aggregate Merger Consideration (the "Deposit Amount").

    Promptly after the Effective Time, the Exchange Agent will mail to each
record holder of certificates for Common Stock that immediately prior to the
Effective Time represented Common Stock of the Company a letter of transmittal
and instructions for use in surrendering such certificates and receiving the
Merger Consideration. Upon the surrender to the Exchange Agent of an outstanding
certificate together with a duly completed and validly executed letter of
transmittal and such other document as the Exchange Agent may require, the
Exchange Agent will deliver the applicable Merger Consideration represented by
such certificate without interest. Any portion of the Deposit Amount that
remains unclaimed for one year after the Effective Time will be delivered by the
Exchange Agent to Actel and any holder of a certificate that immediately prior
to the Effective Time represented Common Stock of the Company may surrender such
certificate to Actel and receive in exchange therefor the Merger Consideration,
without interest, subject in all events to applicable abandoned property,
escheat and similar laws.

    If the amount to be paid from the Deposit Amount upon surrender of a
certificate that immediately prior to the Effective Time represented Common
Stock of the Company, is to be delivered to a person other than the person in
whose name such certificate is registered, it will be a condition to such
payment or exchange that the person requesting such payment or exchange will pay
to the Exchange Agent any transfer or other taxes required by reason of the
payment of such Merger Consideration to a name other than that of the registered
holder of the certificate surrendered, or such person will establish to the
satisfaction of the Exchange Agent that such tax has been paid or is not
applicable.

    STOCKHOLDERS SHOULD NOT FORWARD THEIR STOCK CERTIFICATES WITH THE ENCLOSED
PROXY CARD, NOR SHOULD THEY RETURN THEIR STOCK CERTIFICATES TO THE EXCHANGE
AGENT UNTIL THEY HAVE RECEIVED A LETTER OF TRANSMITTAL FROM THE EXCHANGE AGENT.

STOCK OPTIONS

    At the Effective Time, each option to purchase Common Stock pursuant to the
Company's 1993 Stock Option Plan, as amended, 1996 Stock Option Plan, as
amended, 1999 Stock Option Plan or any other employee or director stock option
plan or arrangement of the Company except the Company's 1995 Directors Plan and
the Company's 1999 Employee Stock Purchase Plan (a "Company Stock Option") that
is then outstanding will be assumed by Actel and converted into an option to
purchase [.16713] shares of Actel Common Stock (rounded down to the nearest
whole share). The exercise price per share of the options assumed by Actel
(rounded up to the nearest penny) will be equal to (A) the former exercise price
per share of the Company Common Stock under such option immediately prior to the
Effective Time divided by (B) [.16713]. In the case of any Company Stock option
that is an "incentive stock option" (as defined in Section 422 of the Internal
Revenue Code), the conversion formula will be adjusted in a manner consistent
with Section 424 (a) of the Internal Revenue Code. As used herein, the "Average
Purchaser Stock Price" means the average of the daily closing price, regular
way, of one share of Actel's Common

                                       22
<PAGE>
Stock (rounded to the nearest thousandth) on the Nasdaq National Market (as
reported in the New York City edition of the Wall Street Journal, or, if not
reported thereby, another nationally recognized source).

not, nor will it authorize or permit any

                                       23
<PAGE>
officer, director, affiliate or agent of the Company or any of its subsidiaries,
to solicit, initiate, entertain or encourage (including by way of furnishing
nonpublic information) any proposals or offers from any party other than Actel
or its affiliates regarding any merger, sale of substantial assets, sale of (or
right to sell) shares of capital stock (other than pursuant to the exercise of
options outstanding on the date of the Merger Agreement) or similar transactions
involving the Company or any of its subsidiaries (any of the foregoing inquiries
or proposals being hereinafter referred to as an "Acquisition Proposal").
Notwithstanding the foregoing, the Company, to the extent required by the
fiduciary obligations of the Company's Board of Directors, may, in response to a
request or inquiry that could reasonably be expected to result in an Acquisition
Proposal, which request or inquiry was unsolicited after the date of the Merger
Agreement, participate in discussions or negotiations with, or furnish
information with respect to the Company to any person. In addition, following
the receipt of an Acquisition Proposal, if the Board of Directors determines in
good faith, that an Acquisition Proposal is more favorable to the Company's
stockholders than the Merger, the Company may terminate the Merger Agreement and
accept such superior proposal, and the Board may withdraw or modify its approval
or recommendation of the Merger Agreement or the Merger.

    The Company has agreed to promptly inform Actel of any inquiry (including
the terms thereof and the identity of the party making the inquiry) which it
receives in respect of an Acquisition Proposal and furnish Actel a copy of any
such written inquiry.

                                  THE COMPANY

DESCRIPTION OF BUSINESS

CURRENT STATUS

    As of May 31, 2000, the Company believes that it will exhaust all of its
currently available capital resources on or about June 30, 2000. The Company
estimates that it will need an additional $6.0 million to $10.0 million to meet
its capital requirements through 2000 and up to an additional $9.0 through 2001.
At this time the Company's 0.25-micron product has experienced significant
lot-to-lot variation and the Company has not qualified these parts for
production. No volume shipments to customer have begun. Even if such production
shipments were to begin immediately, the Company might not be able to ramp its
manufacturing process up to sufficient volumes to satisfy customer demand, if
any.

GENERAL

    The Company designs, develops and markets high-density, high-performance
programmable logic solutions and related development software. The Company was
originally a division of the Zycad Corporation, a leader in the development,
manufacturing and marketing of design verification tools and services. Zycad was
founded in 1981 and became a public corporation in 1984. The GateField division
of Zycad was formed in the third quarter of 1993 to research and develop a new
and innovative semiconductor logic product: a flash technology-based,
high-density field programmable gate array (FPGA) device.

    During 1997, Zycad transitioned from a provider of high-performance
verification products to a provider of FPGA products based on the GateField
division's research and development of an application specific integrated
circuit ("ACIC") technology called ProASIC-TM-. Zycad introduced and first
shipped its 0.72-micron products in 1997. This transition required the sale of
several of Zycad's assets, including: its stock ownership in QSS Inc.; products
and assets relating to its verification product line, including its rights,
title and interest in hardware and software simulation products; and the assets
related to the semiconductor test software product line. In addition, Zycad sold
its maintenance division for the verification products to Zycad TSS, Inc.

    In October 1997, a new management team was put in place and Zycad was
renamed "GateField Corporation". A month later, the Company announced a
strategic alliance with Infineon Technologies AG (formerly Siemens
Aktiengesellschaft) ("Infineon"). In this alliance, Infineon licensed the
ProASIC technology for use in nonstandard FPGA products and purchased the
Company's Common Stock and warrants for $3.25 million. In addition, Infineon
agreed to provide the Company with early access and

                                       26
<PAGE>
foundry service for Infineon's advanced embedded flash technology for the
Company's 0.25-micron products and below. The Company and Infineon concluded a
foundry agreement in June 1998.

    In August 1998, the Company entered into a strategic alliance with Actel,
under which Actel received exclusive, worldwide distribution rights to our
0.35-micron and below standard ProASIC products. Actel also purchased the assets
of our Design Services product line as well as $3.0 million of the Company's
Series C Preferred , which converted prior to the Record Date into an aggregate
of 200,000 shares of Common Stock.

    The Company's products are designed to provide high integration, fast
time-to-market and fast time-to-volume for electronic equipment manufacturers in
the networking, telecommunications, computer, peripheral, industrial control,
instrumentation and consumer markets. When and if the 0.25-micron and below
ProASIC products are successfully produced, they will be subject to exclusive
distribution by Actel. Infineon has agreed to manufacture the 0.25-micron
product in its production facility in Dresden, Germany for the foreseeable
future.

PROPERTIES

    The Company leases approximately 24,000 square feet of office space in
Fremont, California, which is currently used for its headquarters and test and
engineering operations.

    As of May 25, 2000, the Company had a total of 27 full-time employees. The
Company's employees are not represented by any collective bargaining agreement
with respect to their employment by the Company, and the Company has never
experienced an organized work stoppage.

LEGAL PROCEEDINGS

    There are no ongoing legal or material proceedings with respect to the
Company.

(a) Revenues, net income and net income per share for 1995 included amounts
    related to a technology distributed by GateField and owned by a U.K.
    Company. Effective January 1, 1996, the two companies formed a joint
    venture. Consequently, specific revenues and costs related to this product
    were no longer consolidated in GateField's financial statements beginning in
    1996.

(b) Revenues decreased in 1998 and 1997 due to the sale of certain assets of the
    Company (see Note 3 of Notes to Consolidated Financial Statements).

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

RESULTS OF OPERATIONS--THREE MONTHS ENDED MARCH 31, 2000 AND 1999

    REVENUES

    Total revenues for the quarters ended March 31, 2000 and 1999 were $312,000
and $453,000, respectively, a decrease of 31%. Total ProASIC product revenues
for the first quarter of 2000 increased to $312,000 from $142,000 in the first
quarter of 1999. ProASIC product revenues in 2000 consisted entirely of deferred
revenue from license fees from Rohm Co. Ltd. that were collected in fiscal 1998.
ProASIC revenue in the first quarter of 1999 consisted entirely of hardware
sales of its 0.72-micron product that was terminated in 1999. Revenues in the
year 2000, if any, will come from the Company's 0.25-micron products. At this
time, the Company believes 0.25-micron product sales will begin in the third
quarter of 2000. The Company began sampling its 0.25-micron product to initial
customers in the first quarter of 1999 and began shipping engineering samples in
limited volumes in the fourth quarter of 1999. The Company does not expect to
begin shipment of pre-production quality parts for this family until the third
quarter of 2000

                                       28
<PAGE>
and does not expect sales to reach a volume that could generate operating cash
flow break-even in fiscal year 2000. While the Company expects to have the
capacity to produce pre-production parts in volume in the third quarter of 2000
there can be no assurance that sales will indeed begin at that time, if at all.
Nor can there be any assurance how many products will be introduced in 2000 or
in what packages or volumes those products will ship. In addition, it is
impossible to anticipate the degree of market acceptance of this new technology,
or whether it will be accepted at all. Therefore the revenues associated with
the new 0.25-micron product cannot be predicted with any degree of accuracy. The
Company's failure to introduce its 0.25-micron products on a timely basis and to
achieve market acceptance of such products would have a material adverse effect
on the Company's business, financial condition and results of operations.

    Service revenues for the quarters ended March 31, 2000 and 1999 were zero
and $311,000, respectively. Service revenues in 1999 represent the Company's
portion of a profit sharing agreement with the purchaser of the verification
assets that were sold in 1997.

    GROSS PROFIT

    Gross profit for the quarters ended March 31, 2000 and 1999 was $234,000,
and $78,000, respectively. Gross profit as a percentage of total revenues was
75% in the first quarter of 2000 and 17% in the first quarter of 1999.

    Gross profit from ProASIC product revenues for the quarter ended March 31,
2000 was $234,000, which reflected overhead costs required to maintain the
Company's manufacturing capabilities until product sales could begin. Gross
profit deficit from ProASIC product revenues for the quarter ended March 31,
1999 was ($95,000) and related to poor manufacturing yields on the 0.72-micron
product wafers. As the design and manufacturing processes are very different for
the 0.72-micron and the 0.25-micron products, the yields and, hence, the gross
profits on the two products are unrelated. Furthermore, the .25-micron product
has not yet been manufactured in commercial quantities.

    Gross profit from service revenues was $173,000 in the quarter ended
March 31, 1999 and relates to maintenance contracts on the verification systems.
The verification maintenance revenues and, hence, the related gross profits
ceased in 1999 and therefore the Company does not expect any gross margin
contribution from this source in fiscal 2000.

    SALES AND MARKETING

    Sales and marketing expenses were $152,000 for the quarter ended March 31,
2000 and $188,000 for the quarter ended March 31, 1999. Expenses incurred in the
first quarter of 2000 and 1999 related to its efforts to support strategic
initiatives and product designs.

    RESEARCH AND DEVELOPMENT

    Research and development expenses for the quarter ended March 31, 2000 were
$1,604,000 as compared to $1,347,000 for the quarter ended March 31, 1999. The
increase in quarterly expenses is due to mask costs for the 0.25-micron product
development, consulting expenses related to new designs and the cost of
manufacturing engineering lots necessary to develop the 0.25-micron product.

    GENERAL AND ADMINISTRATIVE

    General and administrative expenses for the three months ended March 31,
2000 and 1999 were ($237,000) and $740,000, respectively. The contribution in
the first quarter of 2000 was mainly due to the collection of a $720,000 debt
that was previously written off. The Company also experienced lower legal and
accounting expense as well as reduced labor and overhead expenses associated
with non-engineering activities. The Company expects general and administrative
expenses to be approximately $650,000 per quarter for the remainder of the year.

                                       29
<PAGE>
    OTHER INCOME AND EXPENSES

    Other expenses for the quarter ended March 31, 1999 were $54,000 as compared
to other expenses of $44,000 for the quarter ended March 31, 1998.

RESULTS OF OPERATIONS--FISCAL YEAR ENDED 1999, 1998 AND 1997

    REVENUES

    Total product revenues declined to $1.3 million in 1999 down from $2.6
million in 1998 and $5.4 million in 1997. The 1997 figure includes $2.5 million
in verification products from assets the Company sold in that year. Sales of
ProASIC related products were $1.4 million in 1999, $2.6 million in 1998 and
$2.9 million in 1997. ProASIC product revenue included deferred license revenue
from Infineon and from Rohm of approximately $0.9 million in 1999 and $1.1
million in 1998. The decline in ProASIC revenues from 1997 through 1999 was due
to a decision by the Company to halt active sales of the 0.72-micron product in
the third quarter of 1998 and due to the current delay in shipment of its
0.25-micron product that was scheduled to begin in the second half of 1999.

    Service revenues were $0.6 million, $5.1 million and $10.1 million in 1999,
1998 and 1997, respectively. Service revenues are comprised of two components:
maintenance contracts on the verification systems and design services.
Verification maintenance revenues were $.6 million in 1999, $2.3 million in 1998
and $8.7 million in 1997. The decline in verification maintenance revenues in
1998 from 1997 relates to the sale of the underlying verification products and
the termination of new sales of those products by the purchaser. The Company
expects revenues from the verification services to cease in 2000. Service fees
related to the Company's Design Service product line, which was sold to Actel in
August 1998, were $2.8 million in 1998, and $3.8 million in 1997.

    GROSS MARGIN

    Gross margin in 1999, 1998 and 1997 was affected by many factors, including
but not limited to: license fees, pricing strategies, product mix, yield
variations and increased costs incurred in the introduction of new products.
Gross margin was approximately $690,000 in 1999, $393,000 in 1998 and $4.6
million in 1997. Gross margin as a percentage of total revenues was 35% in 1999,
5% in 1998 and 30% in 1997.

    Gross margin (deficit) from product revenues was $213,000 in 1999, ($2.0)
million in 1998, and $(1.0) million in 1997. Gross margin related to
verification products was ($1.8) million in 1997. Gross margin (deficit) related
to ProASIC products was $.2 million in 1999, $(2.0) million in 1998, ($3.3)
million in 1997. In 1998, negative ProASIC product margins were significantly
affected by a $1.8 million inventory write-down charge for 0.72-micron product
inventories to reflect a decrease in the net realizable value, which was
partially offset by $1.2 million in license revenue with minimal related costs.
The decline in ProASIC gross margins in 1998 versus 1997 were largely due to
volume differences and the inventory write-down charge. As the design and
manufacturing processes are different for the 0.72-micron and the 0.25-micron
products, the yield and, hence, the gross margins on the two products are
totally unrelated, thus, the Company cannot predict its margins for 2000 with
any degree of certainty.

    Gross margin from service revenues was $.5 million in 1999, $2.4 million in
1998, and $5.6 million in 1997. Gross margin as a percentage of service revenues
was 75%, 48%, and 56% for the three years respectively. Margins related to
maintenance contracts on the verification systems were $2.2 million or 69.7% in
1998 and $4.8 million or 77.5% in 1997. Margins related to design services were
$277,000 or 14% in 1998 and $725,000 or 19% in 1997.

    SALES AND MARKETING

    Sales and marketing expenses were $.8 million or 39% of total revenue in
1999, $4.1 million or 53% in 1998, and $9.7 million or 62% in 1997. In 1999,
sales and marketing expenses declined 81% due to the

                                       30
<PAGE>
Company's decision to largely eliminate that function in August of 1998 and
enter into an exclusive marketing agreement with Actel. In 1998, sales and
marketing expenses also decreased 58% or $5.6 million from earlier year figures
reflecting reduced staffing levels in the second half of 1997 resulting from the
disposition of product lines in 1997.

    As a result of our efforts to market its 0.72-micron products in 1997 and
early 1998, the Company realized the process of introducing new products to the
semiconductor marketplace required significant sales and marketing resources.
The Company elected to sell the exclusive worldwide distribution rights to its
0.25 and below standard ProASIC products to Actel in August 1998 and to focus on
product development.

    RESEARCH AND DEVELOPMENT

    The Company's research and development expenses were $5.9 million or 298% of
total revenue in 1999, $5.5 million or 71% of total revenue in 1998 and $7.9
million or 51% of total revenue 1997. Research and development expenses increase
8% in 1999 over 1998 due to $.8 million in wafer costs necessary to refine the
design of the 0.25-micron family and develop the manufacturing process with
Infineon, these costs were partially offset by reduced headcount. A similar
level of wafer costs and masks expense is anticipated in 2000. The 30% decrease
in research and development costs in 1998 over 1997 were principally due to
reduced staffing levels resulting from the sale of the verification businesses
in 1997. Research and development expenses related to ProASIC development have
remained relatively constant over the three-year period from 1997 to 1999. The
Company's current research and development efforts are focused on its four
member 0.25-micron ProASIC product family.

    GENERAL AND ADMINISTRATIVE

    General and administrative expenses were $2.7 million, $3.3 million and $4.2
million in 1999, 1998 and 1997, respectively. This declining trend in general
and administrative expenses in 1999 as compared to 1998 and in 1998 as compared
to 1997 was primarily related to decreased staffing levels, cost cutting
measures and reduced overhead. These reduced expenses were partially offset by
higher legal, financial, and consulting expenses associated with the
implementation of strategic relationships in 1997 and 1998. 1999 expenses
included $.2 million related to a moving the Company's offices to a smaller
facility.

    OTHER INCOME AND EXPENSE

    Net interest expense was $1.3 million in 1999 compared to $173,000 in 1998
and $1.4 million in 1997. The increase in 1999 relates to an $8.0 million
convertible promissory note entered into in May 1999 with Actel, while the
decrease in 1998 reflects the lack of interest-bearing debt compared to earlier
periods and interest income on positive bank balances held throughout the year
due to the Company's issuance of equity at the end of 1997 and during 1998.
Interest expense in 1997 relates primarily to subordinated convertible
debentures that were converted to Common Stock in 1997.

    Other income was $114,000 in 1999, $4.4 million in 1998 and $3.1 million in
1997. These amounts include a $4.5 million gain in 1998 from the sale of the
Design Service assets to Actel, a $2.7 million gain from the sale of the
verification and LightSpeed product families and the sale of the Company's
interest in QSS in 1997. See Note 3 of the "NOTES TO CONSOLIDATED FINANCIAL
STATEMENTS."

    NET LOSS

    The net loss for 1999 was $10.0 million, which compares to a net loss of
$8.3 million in 1998 and a net loss of $16.4 million in 1997. The 1999 figure
includes a $1.2 million Conversion Discount recognized in the second quarter of
1999 as a non-cash interest expense and $.8 million in wafer costs necessary to
develop the manufacturing process at the foundry. Recognizing the impact of
lower sales in these years, the Company took steps to decrease operating
expenses through a series of reorganizations, which helped to

                                       31
<PAGE>
progressively reduce the annual net loss. The Company has maintained its
operating expenses for the last quarters ending December 31, 1999 at
approximately $2.1 million, not including mask expenses, wafer development lots
and write off of obsolete inventory.

    The $8.3 million net loss in 1998 was aided by a $4.5 million gain in other
income from the sale of the Company's Design Services assets to Actel. This
compares to a $16.4 million net loss in 1997 which was also aided by a $2.7
million gain in other income from the sale of certain assets in that year and
offset by $500,000 in debt discount amortization and $1 million debt
extinquishment losses. See Note 3 of the "NOTES TO CONSOLIDATED FINANCIAL
STATEMENTS." The loss in 1998 was additionally impacted by a $2.2 million one-
time inventory write-down charge to cost of sales.

LIQUIDITY AND CAPITAL RESOURCES

    The Company has historically used private offerings of convertible debt and
convertible preferred stock, public and private offerings of common stock, sale
and leaseback arrangements and bank financing and credit lines to finance its
business.

    At March 31, 2000, the Company had cash and cash equivalents of
approximately $4.0 million and a working capital deficit of $1.8 million. During
the first quarter ended March 31, 2000, and the year ended December 31, 1999,
the Company incurred net losses of approximately $1.3 million and $10.0 million,
respectively. The Company expects to continue to generate such losses for at
least the remainder of 2000. As a result, the Company estimates it will have
exhausted all of its currently available capital resources on or about June 30,
2000. Thus, the Company will be unable to continue as a going concern if
sufficient funding is not immediately available.

    Net cash used in operations was $8.8 million in 1999 compared to $8.2
million in 1998 and $11.3 million in 1997. During 1999, 1998 and 1997, there was
a significant decline in the size of the business as the Company transitioned to
a provider of FPGA products Company and sold off its other significant assets
related to non-ProASIC product lines. This decrease in the size of the business
resulted in decreasing accounts receivable, accounts payable and accrued
liabilities balances and decreasing depreciation expenses. The decrease in net
cash used in operations was partially offset in 1998 by the receipt of $4.5
million in license fees resulting in deferred revenue.

    Net cash used in investing activities was $.7 million in 1999 compared to
net cash provided by investing activities of $5.2 million in 1998 and $11.2
million in 1997. The amounts generated in 1998 and 1997 were primarily due to
cash receipts from the disposition of product families. Were the Merger not to
occur, and the Company could obtain additional financing, the Company
anticipated investing a minimum of $300,000 and possibly as much as $1.1 million
in mask sets for its new product families in 2000.

    Net cash generated by financing activities was $10.8 million in 1999, which
compares to $2.9 million in 1998 and $3.0 million in 1997. The increase in 1999
includes the sale of $3.1 million of Common Stock to private investors and the
issuance to Actel of a convertible promissory note in the aggregate principal
amount of $8.0 million. The increase in 1998 was due to the $4.6 million sale of
Common Stock to a single investor in the first quarter of 1998, the $3.0 million
sale of Convertible Preferred Stock in August 1998, offset by the $4.6 million
redemption of the Company's Series B Preferred in December 1998. (See Note 9 of
the "Notes to Consolidated Financial Statements.") The 1997 figure includes the
sale of $4.6 million in Convertible Preferred Stock. SEE NOTE 9 OF THE "NOTES TO
CONSOLIDATED FINANCIAL STATEMENTS."

    Cash used in operations was $251,000 in the first quarter of 2000 compared
to $2.7 million for the first quarter of 1999.

QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

    The Company is exposed to market risk related to fluctuations in interest
rates and in foreign currency exchange rates:

                                       32
<PAGE>
    INTEREST RATE EXPOSURE

    The Company maintains its funds in money market and Certificate of Deposit
accounts at banks. The Company's exposure to market risk due to fluctuations in
interest rates relates primarily to its interest earnings on its cash deposits.
These securities are subject to interest rate risk inasmuch as their fair value
will fall if market interest rates increase. If market interest rates were to
increase immediately and uniformly by 10% from the levels prevailing at December
31, 1999, the fair value of the portfolio would not decline by a material
amount. The Company does not use derivative financial instruments to mitigate
risks. However, it does have an investment policy that would allow it to invest
in short-term investments such as money market instruments and corporate debt
securities. The Company's policy does attempt to reduce such risks by typically
limiting the maturity date of such securities to no more than eighteen months
with a maximum average maturity to its whole portfolio of such investments at
six months, placing its investments with high credit quality issuers and
limiting the amount of credit exposure with any one issuer.

    FOREIGN CURRENCY EXCHANGE RATE EXPOSURE

    The Company's exposure to market risk due to fluctuations in foreign
currency exchange rates relates primarily to the inter-Company balances with its
UK, German and Japanese subsidiaries. The Company closed these subsidiaries in
1999 and only has some insignificant cash balances remaining in these countries.
Although the Company transacts business in various foreign countries, settlement
amounts are usually based on U.S. currency. Transaction gains or losses have not
been significant in the past, and there is no hedging activity on the pound,
mark, yen or other currencies. The Company would not experience a material
foreign exchange loss based on a hypothetical 10% adverse change in the price of
the pound, mark or yen against the U.S. dollar. Consequently, the Company does
not expect that a reduction in the value of such accounts denominated in foreign
currencies resulting from even a sudden or significant fluctuation in foreign
exchange rates would have a direct material impact on the Company's financial
position, results of operations or cash flows.

    Notwithstanding the foregoing analysis of the direct effects of interest
rate and foreign currency exchange rate fluctuations on the value of certain of
the Company's investments and accounts, the indirect effects of such
fluctuations could have a material adverse effect on the Company's business,
financial condition and results of operations. For example, international demand
for the Company's products is affected by foreign currency exchange rates. In
addition, interest rate fluctuations may affect the buying patterns of the
Company's customers. Furthermore, interest rate and currency exchange rate
fluctuations have broad influence on the general condition of the U.S. foreign
and global economics, which could materially adversely affect the Company.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL
DISCLOSURE

    There are no changes in or disagreements with the Company's accountants on
accounting and financial disclosure.

                                       33
<PAGE>
                       CERTAIN EFFECTS OF THE TRANSACTION

    Because all of the Company's Common Stock that is outstanding immediately
prior to the consummation of the Merger will be canceled in exchange for payment
of the cash merger consideration as a result of the proposed merger, the Common
Stock will no longer be traded on the OTCBB. At such time, the Common Stock also
will meet the requirements for deregistration under the Securities Exchange Act
of 1934, as amended, and, once deregistered, the Company will no longer be
required to file periodic reports with the Securities and Exchange Commission.

    Generally, any dividends and other distributions by the Company having a
Record Date prior to the date of completion of the Merger will remain payable to
the Company's stockholders who held their shares on the Record Date. The Company
has never declared or paid any dividends on its capital stock and does not
anticipate paying a final dividend. All other distributions by the Surviving
Corporation after completion of the Merger will be paid to Actel and not to the
Company's current stockholders.

                          INTEREST OF CERTAIN PERSONS

    Directors and executive officers of the Company may have interests, in
addition to their interests as stockholders, which present them with potential
conflicts of interest in connection with the Merger. The Board of Directors
(including the non-management members of the Board) is aware of the potential
conflicts described below and considered them in addition to the other matters
described under "REASONS FOR THE MERGER; RECOMMENDATION OF THE BOARD OF
DIRECTORS."

STOCK OWNERSHIP

    Shares of Common Stock held by officers and directors of the Company will be
converted into the right to receive the same consideration as shares of Common
Stock held by other stockholders.

INDEMNIFICATION

    Pursuant to the Merger Agreement, Actel has agreed for six years after the
Effective Time to indemnify all present and former directors, officers,
employees and agents of the Company and will, subject to certain limitations,
maintain for six years directors' and officers' liability insurance and
fiduciary liability insurance policies containing terms and conditions which are
not less advantageous than any such policies which may be in effect prior to the
Effective Time. See "THE MERGER AGREEMENT--INDEMNIFICATION; INSURANCE."

STOCK OPTION PLANS

    Pursuant to the Merger Agreement outstanding options to purchase Common
Stock (including certain unvested options) previously granted to directors,
executive officers and employees of the Company will be assumed by Actel and
become exercisable for a certain umber of shares of Actel stock. All shares
issued under the Company's option plans will fully vest either upon the
consummation of the Merger or two years thereafter. As a result, 162,854 options
will vest immediately upon the consummation of the Merger, and 95,161 options
will vest over the next two years. Of these options, Mr. Saxe holds 30,533 that
will vest immediately upon the consummation of the Merger, and 30,533 that will
vest over the next two years.

EMPLOYMENT WITH GATEFIELD

    Mr. Saxe is an at-will employee of the Company. He will not receive
additional salary upon a change of control on the Company. Mr. Saxe owns options
to purchase 252,339 shares of Common Stock at prices ranging from $4.00 to $6.44
per share.

                  APPRAISAL RIGHTS OF DISSENTING STOCKHOLDERS

    DISSENTERS' AND APPRAISAL RIGHTS UNDER BOTH DELAWARE AND CALIFORNIA LAW ARE
AVAILABLE TO THE COMPANY'S STOCKHOLDERS IF THE MERGER IS CONSUMMATED. A
STOCKHOLDER'S VOTE AGAINST APPROVAL OF THE MERGER IS NOT SUFFICIENT TO PRESERVE
DISSENTING STOCKHOLDER'S RIGHT TO RECEIVE SUCH APPRAISAL RIGHTS. A DISSENTING
STOCKHOLDER MUST AFFIRMATIVELY COMPLETE CERTAIN PROCEDURES INCLUDING GIVING
NOTICE TO THE COMPANY WITHIN CERTAIN STATUTORY TIME FRAMES IN ORDER TO PRESERVE
THE DISSENTER'S RIGHTS OF APPRAISAL. IMPORTANT DETAILS CONCERNING THESE
REQUIREMENTS ARE SET FORTH BELOW; FAILURE TO TAKE THESE ACTIONS IN A TIMELY AND
PROPER FASHION WILL RESULT IN THE LOSS OF DISSENTERS' APPRAISAL RIGHTS. ALTHOUGH
A DISSENTING STOCKHOLDER MAY PERFECT ITS APPRAISAL RIGHTS UNDER BOTH THE DGCL
AND THE CGCL, ACTEL CAN ONLY BE REQUIRED TO MAKE A "FAIR VALUE" OR "FAIR MARKET
VALUE" PAYMENT UNDER ONE OF SUCH STATE COURT REMEDIES.

    The following is not a complete statement of the law relating to dissenters'
rights and is qualified in its entirety by reference to ANNEX III and ANNEX IV
hereto, Section 262 of the DGCL and Section 1300-1312 of the CGCL, respectively.
This discussion and each of ANNEX III and ANNEX IV should be reviewed carefully

                                       39
<PAGE>
by any stockholder who wishes to exercise dissenters' rights or who wishes to
preserve the right to do so, since failure to comply with the procedures set
forth therein will result in the loss of dissenters' rights.

    All references in CGCL Section 1300-1312 to a "shareholder" and all
references in DGCL Section 262 and in this summary to a "stockholder" are to the
record holder of the shares of the Company's Common Stock as to which appraisal
rights are asserted. A PERSON HAVING A BENEFICIAL INTEREST IN SHARES OF THE
COMPANY'S COMMON STOCK HELD OF RECORD IN THE NAME OF ANOTHER PERSON, SUCH AS A
BROKER OR NOMINEE, MUST ACT PROMPTLY TO CAUSE THE RECORD HOLDER TO FOLLOW THE
STEPS SUMMARIZED BELOW PROPERLY AND IN A TIMELY MANNER TO PERFECT APPRAISAL
RIGHTS.

SECTION 262 OF THE DGCL

    If the Merger is consummated, those stockholders who elect to exercise their
dissenters' rights under Delaware law and who in a timely and proper fashion
perfect such rights, will be entitled to an appraisal by the Delaware Court of
Chancery of the "fair value" of their shares. Pursuant to Section 262 of the
DGCL, such "fair value," together with a fair rate of interest, if any, would be
determined by taking into account all relevant factors, exclusive of any element
of value arising from the accomplishment or expectation of the Merger. The
notice and demand to the Company required under the DGCL and described below
must be received by the Company prior to the Special Meeting.

SECTION 1300 ET SEQ. OF THE CGCL

    If the Merger is consummated, those stockholders who elect to exercise their
dissenters' rights under California law and who in a timely and proper fashion
perfect such rights, will be entitled to file a complaint in the superior court
of the proper California county for determination of the "fair market value" of
their shares. The court, or an appraiser appointed by the court, shall determine
such "fair market value" as of the day before the first announcement of the
terms of the Merger, excluding any appreciation or depreciation caused by the
Merger. THE NOTICE AND DEMAND TO THE COMPANY REQUIRED UNDER THE CGCL AND
DESCRIBED BELOW MUST BE DELIVERED TO THE COMPANY UP TO 30 DAYS FOLLOWING THE
SPECIAL MEETING.

NOTICE TO COMPANY

    If any stockholder elects to demand appraisal of his or her shares of Common
Stock, such holder must satisfy each of the following conditions: (i) the holder
must deliver, in a timely fashion, to the Company a written demand for appraisal
of his or her shares of Common Stock before the vote with respect to the Merger
is taken (this written demand for appraisal must be in addition to and separate
from any proxy or vote abstaining from or against the Merger; voting against or
failing to vote for the Merger by itself does not constitute a demand for
appraisal; and (ii) the stockholder must not vote in favor of the Merger (an
abstention or failure to vote will satisfy this requirement, but a vote in
favor, by proxy (including by returning an executed but otherwise unmarked proxy
card) or in person, will constitute a waiver of the stockholder's appraisal
rights in respect to the shares so voted and will nullify any previously filed
written demands for appraisal). Such demand should be sent to the Company's
offices at 47436 Fremont Boulevard, Fremont, California 94538-6503. Such written
demand must reasonably inform the Company of the identity of the stockholder and
the intention of such stockholder to demand appraisal of his or her shares of
Common Stock.

    If the Merger is approved by the Company's stockholders, Actel will, within
10 days after the affirmative vote, mail to stockholders of record who so filed
a written demand for appraisal and who did not vote in favor of the Merger, a
notice that the required stockholder approval of the Merger was obtained (the
"Notice of Approval"). The Notice of Approval will set forth the price
determined by Actel and the Company to represent the "fair market value" of any
dissenting shares, and will set forth a brief description of the procedures to
be followed by the dissenting stockholders who wish to pursue further

                                       40
<PAGE>
their statutory rights, including a discussion of the time in which written
demand must be made on the Company in order to perfect the right of dissent.

    The statement in the Notice of Approval of the determination of the fair
market value of the dissenting shares will constitute an offer by Actel to
purchase shares from dissenting stockholders at the price stated, assuming the
Merger is consummated. However, the determination by Actel and the Company of
fair market value is not binding on its stockholders, and if a dissenting
stockholder chooses not to accept that offer, he or she has the right during a
period of 6 months following the mailing of the Notice of Approval to commence a
lawsuit to have the fair market value, as described in Section 262 of the DGCL
or Section 1304 of the CGCL, determined by a court. The fair market value as
determined by the court in these circumstances could be higher or lower than the
amount offered by Actel in the Notice of Approval or the consideration provided
for in the Merger Agreement, and any such determination would be binding on the
dissenting stockholder or stockholders involved in the lawsuit and on Actel. Any
party may appeal from the judgment. However, the court action to determine the
fair market value of the shares will be suspended if litigation is instituted to
test the sufficiency or regularity of the votes of stockholders in authorizing
the Merger.

    Dissenting shares may lose their status as such if any of the following
occur: the Merger is abandoned (in which case the Company shall pay on demand to
any stockholder who has initiated proceedings in good faith as provided under
appropriate law all necessary expenses and reasonable attorneys' fees incurred
in such proceedings); the shares are transferred before being submitted to the
Company for endorsement; the stockholder withdraws his or her demand with the
consent of the Company; or, in the absence of agreement between the stockholder
and the Company as to the price of his or her shares, the stockholder fails to
file suit against the Company or otherwise fails to become a party to such suit
within 6 months following the mailing of the Notice of Approval.

    FAILURE TO FOLLOW THE STEPS OUTLINED HEREIN FOR PERFECTING APPRAISAL RIGHTS
MAY RESULT IN THE LOSS OF SUCH RIGHTS (IN WHICH EVENT A STOCKHOLDER WILL BE
ENTITLED TO RECEIVE THE MERGER CONSIDERATION IN ACCORDANCE WITH THE MERGER
AGREEMENT FOR EACH SHARE OF COMMON STOCK HELD BY SUCH STOCKHOLDER).

                              INDEPENDENT AUDITORS

    Deloitte & Touche LLP are the Company's independent auditors.
Representatives of Deloitte & Touche LLP are expected to be present at the
Special Meeting, where they will have the opportunity to make a statement if
they desire to do so and will be available to respond to appropriate questions.

               STOCKHOLDER PROPOSALS FOR THE 2001 ANUUAL MEETING

    If the Merger is not consummated, the Company will hold its 2001 Annual
Meeting of its stockholders in accordance with its Bylaws and the DGCL. Any
proposals of stockholders to be presented at the 2001 Meeting were required to
have been received by the Secretary of the Company for inclusion in the
Company's Proxy Statement and form of Proxy no later than December 28, 2000.

                                 OTHER MATTERS

    The Board of Directors knows of no other matters that may properly be, or
which are likely to be, presented for consideration at the Special Meeting. If
any other matters are properly brought before the Special Meeting, it is the
intention of the persons named in the accompanying Proxy to vote on such matters
in accordance with their best judgment.

    It is important that your shares be represented at the Special Meeting,
regardless of the number of shares, which you hold. You are, therefore, urged to
execute and return, at your earliest convenience, the accompanying Proxy in the
envelope which has been enclosed.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

                                  (UNAUDITED)

                                 MARCH 31, 2000

1. BASIS OF PRESENTATION

    The accompanying financial statements have been prepared on a going concern
basis, which contemplates the realization of assets and the satisfaction of
liabilities in the normal course of business. As shown in the financial
statements, during the quarters ended March 31, 2000 and 1999, GateField
Corporation, (the "Company" or "GateField") incurred net losses of approximately
$1,339,000 and $2,241,000, respectively. Additionally, the Company had
stockholders' deficits of approximately $11,548,000 at March 31, 2000 and
$10,297,000 at December 31, 1999, and is highly dependent on obtaining
additional financing in order to fund current and planned operating levels.
These factors among others raise substantial doubt about the ability of the
Company to continue as a going concern for a reasonable period of time.

    The financial statements do not include any adjustments relating to the
recoverability and classification of recorded asset amounts or the amounts and
classification of liabilities that might be necessary should the Company be
unable to continue as a going concern. The Company's continuation as a going
concern is dependent upon its ability to obtain additional financing to complete
its new product development and begin commercial sales, and ultimately obtain
sufficient customer demand to attain profitable operations. Management intends
to maintain operating expenses at current or slightly higher levels, begin sales
of new products currently in development and obtain additional financing to
cover its additional cash flow requirements until it reaches a break-even level
of operations. No assurance can be given that the Company will be successful in
these efforts.

    Interim results of operations are not necessarily indicative of the results
to be expected for the full year. The Company's interim fiscal quarter ended on
March 31, 2000 and 1999, respectively. In the opinion of the Company, all
adjustments (consisting only of normal, recurring adjustments) necessary to
present fairly the financial position, results of operations and cash flows at
March 31, 2000, and for all periods presented, have been made. These condensed
financial statements should be read in conjunction with the financial statements
and notes thereto included in the Company's December 31, 1999 Annual Report on
Form 10-K.

2. LETTER OF INTENT TO MERGE

    On May 11, 2000, GateField Corporation and Actel Corporation announced the
signing of a letter of intent. In the merger, Actel would pay cash consideration
of $5.25 per share of GateField Common Stock not already owned by Actel
(approximately 4.5 million shares). Actel would also assume all outstanding
GateField stock options. The merger is subject to several conditions, including
execution by the parties of a definitive agreement and approval by GateField's
stockholders at a special meeting. In the definitive agreement, Actel will agree
to convert its $8.0 million Convertible Promissory Note into GateField Preferred
Stock and Actel and Idanta Partners, Ltd. will agree to convert their GateField
Preferred Stock into GateField Common Stock before the record date for the
special meeting and to vote their shares of GateField Common Stock for approval
of the merger.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                  YEARS ENDED DECEMBER 31, 1999, 1998 AND 1997

NOTE 1: ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION AND OPERATIONS

    GateField Corporation, (the "Company"), based in Fremont, California,
designs, develops, manufactures and markets high density, high performance
programmable logic solutions and related development software. During 1998, the
Company disposed of its system engineering services and custom solutions assets
(see Note 3). During 1997, the Company disposed of its verification and
simulation assets (see Note 3).

    On July 16, 1998 the Company's common stock was delisted from the Nasdaq
National Market (a distinct tier of the Nasdaq Stock Market) and moved to the
Nasdaq SmallCap Market. Effective September 17, 1998 the Company's stock was
delisted from The Nasdaq SmallCap Market for failure to meet the on-going
minimum bid price requirement. Since that time, the Company's stock has traded
on the OTC Bulletin Board.

    The Company reviewed its strategies, organization and expenses in the fourth
quarter of 1998 and as a result of management actions, reduced its monthly cash
expenditures. Management's plan in 2000 is to maintain the level of operating
expenses it established in the fourth quarter of 1999, begin volume shipment of
its .25-micron standard ProASIC products manufactured by Infineon, and to obtain
additional financing. Because the Company is essentially a restart, its
historical financial performance cannot and should not be used to indicate
future financial performance.

    In June 1999, the Company effected a ten-for-one reverse stock split. All
shares and per share amounts in these financial statements have been adjusted to
give effect to the stock split.

BASIS OF PRESENTATION

    The accompanying financial statements have been prepared on a going concern
basis, which contemplates the realization of assets and the satisfaction of
liabilities in the normal course of business. As shown in the financial
statements, during 1999, 1998 and 1997, the Company incurred net losses of
approximately $10.0 million, $8.3 million and $16.4 million, respectively.
Additionally, the Company had stockholders' deficits of approximately
$10.3 million and $5.0 million at December 31, 1999 and 1998, respectively, and
is highly dependent on its ability to obtain sufficient additional financing in
order to fund the current and planned operating levels. These factors among
others raise substantial doubt about the ability of the Company to continue as a
going concern for a reasonable period of time.

    The financial statements do not include any adjustments relating to the
recoverability and classification of recorded asset amounts or the amounts and
classification of liabilities that might be necessary should the Company be
unable to continue as a going concern. The Company's continuation as a going
concern is dependent upon its ability to obtain additional financing to complete
its new product development and begin commercial sales, and ultimately obtain
sufficient customer demand to attain profitable operations. Management intends
to reduce operating expenses, begin sales of new products currently in
development and obtain additional financing to cover its additional cash flow
requirements until it reaches a break-even level of operations. No assurance can
be given that the Company will be successful in these efforts.

                  YEARS ENDED DECEMBER 31, 1999, 1998 AND 1997

NOTE 1: ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
RECLASSIFICATIONS

    Certain prior period amounts have been reclassified to conform to the 1999
presentation. Such reclassification had no effect on previously reported results
of operations or financial position.

PRINCIPLES OF CONSOLIDATION AND PRESENTATION

    The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiary. All intercompany accounts and transactions have
been eliminated in consolidation. The functional currency of the Company's
foreign subsidiaries is the local currency.

ESTIMATES IN PREPARATION OF FINANCIAL STATEMENTS

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and reported amounts of revenues and expenses during the reporting
period. Actual results could differ from those estimates.

BUSINESS RISKS AND UNCERTAINTIES

    The Company participates in a dynamic high technology industry and believes
that changes in any of the following areas could have a material adverse effect
on the Company's future financial position or results of operations: dependence
on independent wafer manufacturers and assembly subcontractors; changes in
certain strategic partners or customer relationships; competitive pressures in
the form of new products or price reductions on existing products; advances and
trends in new technologies; ability to capture design wins; cyclical economic
effects of the semiconductor industry; litigation or claims against the Company
based on intellectual property, patent, product, regulatory or other factors and
the Company's ability to attract and retain employees necessary to support its
growth.

CASH EQUIVALENTS

    Cash and cash equivalents consist of cash on deposit with banks and money
market instruments with maturities of three months or less when acquired.

SHORT-TERM INVESTMENTS

    Short-term investments consist of Certificates of Deposit, stated at cost
plus accrued interest, which approximates market.

CONCENTRATION OF CREDIT RISK

    Financial instruments that potentially subject the Company to concentrations
of credit risk consist primarily of cash and cash equivalents and trade accounts
receivable. The Company invests in high credit quality short-term money market
instruments and certificates of deposit and limits the amount of credit exposure
to any one entity. The majority of the Company's trade accounts receivables are
derived from sales to manufacturers in the semiconductor, computer, military and
aerospace industries. The Company

NOTE 1: ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
performs ongoing credit evaluations of its customers' financial condition and
limits the amount of credit extended when deemed necessary, but generally
requires no collateral. The Company maintains reserves for estimated potential
credit losses.

INVENTORIES

    Inventories are stated at the lower of standard cost, which approximates
actual cost on a first-in, first-out basis, or market.

PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost. Equipment acquired under capital
lease obligations is stated at the lower of fair value or the present value of
future minimum lease payments at the inception of the lease. Depreciation and
amortization is provided over the shorter of the estimated useful lives of the
assets or the life of the lease, using the straight-line method. An impairment
loss is recognized when estimated future cash flows expected to result from the
use of the asset including disposition, is less than the carrying value of the
asset.

INCOME TAXES

    The Company follows Statement of Financial Accounting Standards No. 109
(SFAS No. 109), "Accounting for Income Taxes," which requires an asset and
liability approach to account for income taxes and requires recognition of
deferred tax liabilities and assets for the expected future tax consequences of
temporary differences between the financial statement carrying amounts and the
tax basis of assets and liabilities and net operating loss and tax credit
carryforwards. Valuation allowances are provided when necessary to reduce net
deferred tax assets to an amount that is more likely then not to be realized.

STOCK-BASED COMPENSATION

    The Company accounts for stock-based awards to employees using the intrinsic
value method in accordance with Accounting Principles Board No. 25 (APB
No. 25), "Accounting for Stock Issued to Employees".

REVENUE RECOGNITION

    The Company recognizes product revenues at the time of shipment, but may
delay revenue recognition until products are installed or accepted, depending on
the particular product and contract terms. Design and verification service
revenues are recognized as the services are performed. Revenues from the sale of
maintenance contracts are recognized over the term of the respective contract.
ProASIC products are shipped to Actel who in turn may ship them to distributors
under agreements allowing certain rights of return and price protection on
unsold merchandise. Because of this two-layer process of sales, the Company
defers recognition of revenue and related cost of revenue on sales of products
to Actel until such products are sold by Actel or Actel's distributors.

    In 1998, the Company adopted Statement of Position ("SOP") 97-2, "Software
Revenue Recognition," which requires revenue earned on software arrangements
involving multiple elements to be allocated to each element based on the
relative fair values of the elements. Revenue for software licenses

                                       53

NOTE 1: ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
included in product revenues is recognized when an agreement has been signed,
the product has been shipped, the fee is fixed or determinable, and collection
of resulting receivable is probable. Software support and maintenance revenue
are deferred and amortized over the maintenance period on a straight-line basis.
Adoption of this statement did not have a material impact on the Company's
financial position, results of operations and cash flows.

NET INCOME (LOSS) PER SHARE

    Basic earnings per share ("EPS") excludes dilution and is computed by
dividing net income or loss attributable to common stockholders by the weighted
average of common shares outstanding for the period. Diluted EPS reflects the
potential dilution that could occur if securities or other contracts to issue
common stock (convertible preferred stock, warrants to purchase common stock and
common stock options using the treasury stock method) were exercised or
converted into common stock. The following potential weighted average common
shares in the diluted EPS computation are excluded in net loss periods, as their
effect would be antidilutive.

    In the computation of loss per share, loss attributable to common
stockholders includes the accretion and dividends on Preferred Stock totaling
$6,293,000 in 1997 and the accrual of dividends on Preferred Stock of $3,000 and
$137,000 in 1999 and 1998, respectively.

COMPREHENSIVE LOSS

    In 1998, the Company adopted Statement of Financial Accounting Standards
("SFAS"), No. 130, "Reporting Comprehensive Income," which requires an
enterprise to report, by major components and as a single total, the change in
net assets during the period from nonowner sources. Statements of comprehensive
loss for 1999, 1998 and 1997 have been included with the statements of
operations.

GEOGRAPHIC AND OPERATING SEGMENT INFORMATION

    In 1998, the Company adopted SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information," which establishes annual and interim
reporting standards for an enterprise's business segments and related
disclosures about its products, services, geographic areas and major customers.
The Company has two reportable segments under SFAS No. 131 (Note 8).

RECENTLY ISSUED ACCOUNTING STANDARDS

    In June 1998, the FASB issued SFAS No. 133 "Accounting for Derivative
Instruments and Hedging Activities." This statement requires companies to record
derivatives on the balance sheet as assets or liabilities, measured at fair
value. Gains or losses resulting from changes in the values of those derivatives
would be accounted for depending on the use of the derivative and whether it
qualifies for hedge

NOTE 1: ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
accounting. SFAS No. 133 will be effective for the Company's fiscal year ending
December 31, 2001. Management believes that these statements will not have a
significant impact on the Company's financial position, results of operations or
cash flows.

NOTE 2: STRATEGIC ALLIANCES

PRODUCT MARKETING AGREEMENT

    In August 1998, the Company and Actel Corporation ("Actel") entered into a
Product Marketing Agreement (the "Marketing Agreement"). Under the terms of the
Marketing Agreement, Actel received exclusive, worldwide distribution rights to
the Company's standard ProASIC FPGA products utilizing less than 0.35-micron
geometries, including FPGA products that are integrated with SRAM or Flash
memory and all resulting next generation reduced process geometry ProASIC FPGA
products. For these rights, Actel agreed to pay the Company an initial fee of
$1.0 million and a $1.0 million fee upon qualification of the initial .25-micron
product. Revenue recognition of the $1.0 million initial fee received has been
deferred until delivery of pre-production quality parts to Actel of products
below 0.35-micron.

ACTEL LICENSE AGREEMENT

    In August 1998, the Company and Actel entered into a license agreement
pursuant to which the Company granted to Actel a fully paid, non-exclusive,
non-transferable license to sell and upon certain events, make, have made,
import and use the Company's standard ProASIC FPGA products below 0.35-micron
and all resulting next generation reduced process geometry ProASIC FPGA products
(the "Actel License Agreement"). Actel agreed to pay the Company a $1.0 million
fee for such license. Revenue recognition of the $1.0 million license fee
received has been deferred until delivery of pre-production quality parts to
Actel of products below 0.35-micron.

ROHM LICENSE AGREEMENT

    In July 1998, the Company and Rohm Co., Ltd. ("Rohm") entered into a license
agreement (the "Rohm License Agreement"). Pursuant to the Rohm License
Agreement, the Company granted to Rohm for a license fee of $2.5 million: (i) a
worldwide, nonexclusive and royalty-free license of the Company's ProASIC
Technology for Standard ProASIC and embedded products down to 0.35-micron with
no limitation on density; and (ii) a license for 0.25-micron and below embedded
products with a per unit royalty. Revenue recognition of the $2.5 million
license fee was initially deferred but is currently being recognized as the
underlying work is performed.

INFINEON LICENSE AGREEMENT

    In October 1997, the Company and Infineon Technologies, ("Infineon")
formerly Siemens AG entered into a license agreement (the "Infineon License
Agreement"). Pursuant to the Infineon License Agreement, the Company sold to
Infineon for an unlimited, worldwide, non-exclusive right and license to use the
technology, software, engineering services, and equipment related to ProASIC
products; 50,000 shares of common stock and warrants to purchase 9.9% of the
Company's outstanding common stock for a fee of $3,250,000. In 1997, the Company
received $1,500,000, of which $761,000 was allocated to the shares

NOTE 3: LOSS (GAIN) ON SALE OF ASSETS

DESIGN SERVICES

    In August 1998, the Company sold certain assets relating to its Design
Services products, providing prototyping design services and verification
services for electronic systems, integrated circuits and other electronic
components, located in Mt. Arlington, New Jersey to Actel. The purchase price
for such assets was (i) $5.4 million plus (ii) contingent payments to be paid
over a three-year period on a quarterly basis based on Design Services achieving
certain profitability levels which payments shall not exceed $1.0 million in the
aggregate. The Design Services represented approximately 17% of 1998 revenues.
See table below for details of the transaction.

VERIFICATION PRODUCT

    In August 1997, the Company sold its assets relating to its verification
products, excluding the maintenance and support business, for a total of
$4,450,000. As defined in the purchase agreement, all of the rights, title and
interest to the intangible assets of the XP and PXP hardware fault simulation
product business were sold for $2,200,000. In a separate agreement, all of the
assets of the Attest division were sold for $2,250,000. The verification
products represented approximately 16% of 1997 revenues. See table below for
details of the transaction.

    In October 1997, as a result of the Company selling its rights, title, and
interest in the assets of the XP and PXP hardware fault simulation product, the
Company transferred its related maintenance contracts to Zycad TSS Corporation
("Zycad TSS") in October 1997 for future royalties. Zycad TSS is a Company
formed by former employees of the Company to perform maintenance services. The
agreement with Zycad TSS entitles the Company to receive 30% of all domestic
XP/PXP maintenance revenue in the first two years and 10% in the third year. In
addition, the Company is generally entitled to receive 10% of Japanese revenues
for the first five years up to a $1.8 million.

TERM LOANS

    In May 1999, the Company issued a convertible promissory note in the
aggregate principal amount of $8.0 million (the Note). The Note accrues interest
at 5.22% per annum, has a five-year term and is secured by a lien against all
the assets of the Company. The Note is convertible into 420,000 shares of the
Company's Series C-1 Convertible Preferred Stock. The Series C-1 Convertible
Preferred Stock is in turn convertible into 1,230,769 shares of the Company's
common stock, or the equivalent price of $6.50 per share of common stock.

    The Note is convertible at the option of the noteholder. On the date of
issuance, the Note was convertible into common stock at a price equal to
approximately a 13% discount (the Conversion Discount) to the closing market
price as reported on the OTCBB. The Company recognized the Conversion Discount
of $1.2 million during the second quarter of 1999 as a non-cash interest expense
with a corresponding increase in the common stock additional paid in capital.

    In 1997, the Company obtained promissory notes from key vendors that bear
interest rates from 12% to 18%. At December 31, 1997 all amounts were classified
as current positions of long-term obligations.

SUBORDINATED CONVERTIBLE DEBENTURE NOTES

    In May 1996, the Company sold a total of $10,000,000 of subordinated
convertible debenture notes (the "Notes") to institutional investors as part of
a private placement. The Notes accrue interest at an annual rate of 6%,
beginning on the date of issue, with the principal due and payable three years
from the date of issue if and to the extent that the Notes are not previously
converted. The Notes were convertible at the option of the noteholders into
Common Stock at a price equal to 80% to 85% of the average closing bid price for
the Common Stock on the Nasdaq National Market for the five trading days prior
to the date of conversion. During 1997, an aggregate of $5,998,000 ($5,700,000
of the original principal of the Notes and $298,000 of accrued interest) were
converted into 741,800 shares of Common Stock.

    In February 1997, the Company completed a $3,500,000 private placement with
investors whereby the Company issued 6% Subordinated Convertible Debentures (the
Debentures) with warrants to purchase 50,000 shares of Common Stock at $22.50
per share. The warrants are valued at $850,000 and recorded as a discount to the
debentures. The Debentures accrue interest at an annual rate of 6%, beginning on
the date of issue, with principal due and payable three years from the date of
issue, if and to the extent that the Debentures are not previously converted.
The Debentures are convertible at the option of the holder into the Company's
Common Stock at a discount up to 20% from market price (the Conversion Discount)
resulting in debenture discount of $875,000. In May 1997, the Debentures were
converted into 100,000 shares of the Company's Series A Convertible Preferred
Stock ("Series A Stock") having an aggregate stated value of $3,500,000. In
addition, Preferred Stock Purchase Warrants (the "Preferred Warrants") were
issued to the holders of the Debentures to purchase a total of 42,858 shares of
the Series A Stock. The conversion of the debentures to Series A Stock resulted
in a debt extinguishment loss of $1,048,000. During the year ended December 31,
1997, a total of $456,000 was recorded as interest expense relating to the
Debentures and $272,000 was recorded as accrued dividends on the Series A Stock.
The interest expense and dividend principally include a charge for the
Conversion Discount and default discounts. During 1997, 51,972 shares of the
Series A Preferred Stock were converted to 454,693 shares of the Company's
Common Stock. In August 1997, the Company redeemed all of the remaining
outstanding shares of the Company's Series A Stock and the Preferred Warrants
for $1,827,000 and all of the outstanding common stock warrants were exchanged
for 35,000 warrants for the Company's Common Stock at an exercise price of $5.30
per share. A preferred dividend of $144,000 was recognized for the excess of the
redemption price over the carrying amount of the preferred stock. During 1997,
10,500 of the warrants were exercised for $56,000.

</TABLE>

    The net change in the total valuation allowance for the year ended
December 31, 1999 was a net increase of $2,107,000. The increase in the
valuation allowance was primarily a result of increased net operating loss and
tax credit carryforwards and capitalized research and development costs
generated in 1999 which the Company provided a full valuation allowance against
based on the Company's evaluation of the likelihood of realization of future tax
benefits resulting from the deferred tax assets.

    Net pretax foreign income (losses) were $65,000, ($405,000) and ($93,000) in
1999, 1998 and 1997, respectively. The Company has net operating loss
carryforwards of approximately $80,700,000 for federal tax purposes and
$18,162,000 for state tax purposes that will begin to expire in 2005 and 2000,
respectively. Of the $18,162,000 net operating loss carryforwards for state tax
purposes, $94,000 will expire in 2000, $3,056,000 in 2001 and $8,042,000 in
2002. The Company's tax credit carryforwards of $1,922,000 and $1,133,000 are
available to reduce future federal and California income taxes, respectively. Of
the $1,922,000 tax credit carryforwards for federal income tax purposes,
$636,000 will expire in 2000, $962,000 in 2001 and $39,000 in 2002. The Company
also has foreign net operating loss carryforwards of approximately $3,057,000
that may be used to offset future foreign taxable income.

    The Tax Reform Act of 1986 and California Conformity Act of 1987 impose
substantial restrictions on the utilization of net operating losses and tax
credit carryforwards in the event of an "ownership change" as defined by the
Internal Revenue Code. If there should be such a change, the Company's ability
to utilize the stated carryforwards could be significantly limited.

NOTE 8: GEOGRAPHIC SEGMENT AND OPERATING INFORMATION

    Operating segments are defined as components of an enterprise about which
separate financial information is available that is evaluated regularly by the
chief operating decision-maker. Using this definition the Company operates in
two reportable segments: product and services and follows the requirements of
SFAS 131, "Disclosures about Segments of an Enterprise and Related Information."
In 1997 through 1999 these segments reflect the Company's transition from the
design, development and marketing of special purpose systems for the EDA market
to the design, development, and marketing of high density, high performance
programmable logic solutions and related development software. Included in the
product segment are all hardware, software and license revenue and costs related
to the Company's

Company evaluated performance and allocates resources based on the gross margin
of the reportable segments and does not identify assets to any segment.

NOTE 9: STOCKHOLDERS' EQUITY

REDEEMABLE PREFERRED STOCK

    On November 10, 1997, the Board of Directors authorized the designation of
1,000,000 shares of preferred stock, par value $0.10 per share, as Series B
Preferred Stock ("Series B Preferred Stock"). In November 1997, the Company
issued 1,000,000 shares of Series B Preferred Stock for $4.6 million. Each share
is convertible into .45825 shares of Common Stock at the discretion of the
holder and accrues a dividend of $0.137475 per share per annum. The holders of
outstanding shares of Series B Preferred Stock are entitled to vote as a
separate class with respect to certain actions (as defined by the preferred
stock agreement) by the Company. The Company has granted demand registration
rights for the common stock to be issued pursuant to the conversion.

    In addition, the Certificate of Designation of the Series B Convertible
Preferred Stock requires the Company to maintain a listing on a public market
(as defined in the agreement). In the event of default, the holders of the
Series B Preferred Stock can redeem the preferred stock at a redemption price of
$4.5825 in cash per share plus accrued and unpaid dividends thereon or be
convertible, at the option of the holder, into .611 shares of Common Stock.
Effective September 17, 1998 the Company's stock was delisted from The Nasdaq
SmallCap Market. In October 1998 certain holders of its Series B Preferred Stock
requested redemption and on December 16, 1998 the Company redeemed an aggregate
of 981,997 shares of its Series B Preferred Stock at a price equal to $4.5825
per share plus accrued and unpaid dividends for an aggregate cash redemption
price of approximately $4.6 million. A total of 18,003 shares of the Series B
Preferred Stock remain outstanding as of December 31, 1999.

    On August 14, 1998, the Company issued 300,000 shares of the Company's
Series C Convertible Preferred Stock ("Series C Preferred Stock"), par value
$0.10, for an aggregate purchase price of $3,000,000 to Actel Corporation
("Actel"). The Series C Preferred Stock are initially convertible into 200,000
shares of the Company's common stock, are entitled to certain liquidation rights
and are redeemable in the event that all of the Company's remaining outstanding
shares of Series B Preferred Stock are redeemed.

COMMON STOCK

    The Company's Certificate of Incorporation was duly amended by a proposal by
the Board of Directors on November 10, 1997 and by vote of the stockholders at
the Annual Meeting of Stockholders on December 15, 1997, to increase the
Company's Common Stock from 40,000,000 shares to 65,000,000

shares of Common Stock authorized at $0.10 par value. At December 31, 1999 there
were 4,693,038 shares of the Company's Common Stock outstanding including 50,000
unissued shares of subscribed stock.

    In October 1997, the Company entered into a $3,250,000 Strategic Partnership
Agreement with Infineon, which principal terms included the delivery of
technology, software, equipment, engineering services, a warrant to purchase
Common Stock, and 50,000 shares of Common Stock. The Company has valued the
Common Stock at $761,000 and the warrant to purchase common stock at $900,000
(see Warrants). At December 31, 1997, $739,000 cash related to the warrants had
been received and the remaining $161,000 was received during 1998. At
December 31, 1999, subscribed stock represents cash received for this Common
Stock, which has not been issued as of that date.

    In March 1999, the Company's Board of Directors approved a ten for one
reverse stock split of the Company's common stock. In June 1999, the Company's
shareholders approved the reverse stock split. The reverse split became
effective on June 30, 1999 (the "Effective Date"). No fractional shares were
issued. In lieu of any such fractional share interest, each holder will receive
cash in an amount equal to the product obtained by multiplying (i) the closing
sales price of the Company's Common Stock on the Effective Date as reported on
the OTCBB by (ii) the number of shares of Common Stock held by such holder that
would otherwise have been exchanged for such fractional share interest.

STOCK COMPENSATION PLANS

    EMPLOYEE PLANS.

    The 1993 Stock Option Plan (the "1993 Plan"), as amended, provides for
300,000 shares of Common Stock to be issued under the 1993 Plan.

    The 1996 Stock Option Plan (the "1996 Plan"), as amended, provides for
200,000 shares of Common Stock to be issued under the 1996 Plan.

    The 1999 Stock Option Plan (the "1999 Plan"), as amended, provides for
300,000 shares of Common Stock to be issued under the 1999 Plan.

    Under the Company's stock option Plans, incentive stock options granted must
have a per share exercise price of not less than the fair market value per share
at the date of grant. Non-qualified stock options may be granted at such price
as may be determined by the Board of Directors. Dependent upon the Plan, options
generally vest at specific intervals over a three to four year period and expire
eight to ten years after the grant date. In the event of termination, the
Company has the right to cancel any vested options not exercised within 90 days
of termination.

    In July 1997, the Board of Directors authorized the exchange of outstanding
stock options held by all employees for new options with an exercise price of
$4.70 per share, the fair market value of the Common Stock on such date. In
return, participating employees who chose to exchange their options agreed to
accept stock options which will vest on a quarterly basis upon achievement of
certain management goals to be established quarterly for each such employee, or
in any event, in July 1999, should the employee still be employed by the
Company. Options covering a total of 174,410 shares were exchanged under this
program. The effect of such exchange reduced the weighted average exercise price
of the outstanding options from $17.90 to $8.00 per share.

NOTE 9: STOCKHOLDERS' EQUITY (CONTINUED)
NON-EMPLOYEE PLANS.

    During 1995, stockholders approved a Non-Employee Directors' stock option
plan (the "Director Option Plan") whereby 20,000 shares of common stock have
been reserved for issuance. Under the Company's Director Option Plan, each
non-employee director initially elected to the Board of Directors in the future
will be granted an option, upon his or her initial election as a director, to
purchase 1,500 shares of common stock. Each non-employee director is also
entitled to receive an option for 750 shares on the date of each Annual Meeting
of Stockholders. All options granted under the Director Option Plan have or will
have an exercise price equal to the fair market value of the common stock on the
date of grant and expire ten years from the date of grant (subject to earlier
termination in the event the optionee ceases to serve as a director of the
Company). Under the Director Option Plan, options from an Initial Grant vest in
full two years after the date of grant. Options from an Annual Grant vest one
year after the date of grant and the right to exercise vested options terminate
one year after a Director ceases to be a director. The Company granted 1,500,
3,750 and 3,750 options to purchase Common Stock at $8.10 to $15.00 per share to
non-employee directors in 1999, 1998 and 1997, respectively, of which 3,750 and
1,500 option grants were canceled in 1999 and 1998, respectively.

EMPLOYEE STOCK PURCHASE PLAN

    Through the Company's 1999 Employee Stock Purchase Plan (the "1999 Plan"),
eligible employees of the Company may purchase common stock at 85% of the fair
market value of the stock at the beginning or end of each offering period
(12 months except for the initial period which is 18 months), whichever is
lower. Each participant may contribute up to 15% of total compensation, to a
maximum of $25,000 annually. Additionally, each participant is prohibited from
participation if he owns more than 5% of the Company's common stock. The maximum
number of shares available for purchase under the plan during any six-month
purchase period is 20,000 shares, thus, the plan is designed to last a minimum
of five purchase periods. The 1999 Plan was approved by the stockholders in
June 1999 with an initial 100,000 shares of which 19,362 shares were issued at
the end of the first purchase period in February 2000, at a purchase price of
$3.35 per share. Simultaneous with the creation of the 1999 Plan the Company
terminated its 1987 ESPP (the "Old Plan") which was created in May 1987 with an
initial 10,000 shares of Common Stock and added to over the ensuing years in
blocks of 20,000 until a total of 70,000 shares had been authorized by May of
1998, of which a total of 60,500 shares had been issued at December 31, 1999.
During 1999, 8,083 shares were purchased under the Old Plan for prices ranging
from $6.20 to $7.60 with an average price of $6.89 per share. The fair value of
the 1999 awards under both plans was not considered significant.

ADDITIONAL STOCK PLAN INFORMATION

    In October 1995, the Financial Accounting Standards Board issued SFAS
No. 123, which establishes financial accounting and reporting standards for
stock-based employee compensation plans. This statement defines a fair value
based method of accounting for an employee stock option of similar equity
instrument. Under this method, compensation costs are measured at the grant date
based on the value of the award and are recognized over the service period,
which is the vesting period. The Company continues to account for its
stock-based awards using the intrinsic value method in accordance with APB
No. 25 and its related interpretations. Had compensation cost for the Company's
various stock option plans been

    The fair value of each option grant is estimated on the date of grant using
Black-Scholes option-pricing model with the following weighted average
assumptions used for grants in 1999, 1998 and 1997 respectively; expected
volatility of 137% for 1999, 157% for 1998 and 145% for 1997, dividend yield of
0%, risk-free interest rates of 4.78%, 4.60%, and 5.91% for 1999, 1998, and 1997
respectively, and expected lives from the grant date of 7.5 years for 1999,
6.5 years for 1998, and 3.5 years for 1997.

WARRANTS

    At December 31, 1999, total warrants outstanding were 377,625. Purchase
price of the securities subject to these warrants range from $5.30 to $14.40 and
they expire at various dates through November 2005.

    In April 1999, James R. Fiebiger exercised 5,000 warrants granted in
July 1997 at an option price of $4.70 per share.

    In November 1997, the Company entered into a Stock Purchase Agreement ("the
Agreement") in connection with the Series B Preferred Stock financing. Pursuant
to this Agreement, the Company issued warrants to purchase 997,751 shares of
common stock at $1.00 per share. In January 1998, the warrants expired in
accordance with the Agreement upon approval by the stockholders of an increase
in the Company's authorized common stock and the closing of the common stock
financing contemplated by the Agreement.

    In October 1997, the Company entered into a licensing agreement under which
the Company granted a stock warrant to purchase 9.9% of its outstanding shares
of Common Stock to a strategic partner at an exercise price equal to 80% of the
Market Price of the Company's Common Stock on the trading day immediately prior
to the date of exercise, subject to a minimum exercise price of $10.00 per
share. Market Price is defined as the last trade price for common stock as
reported on the Nasdaq. In the event that the strategic partners' interest is
decreased to less than 9.9% by future equity offerings, they will have the right
to increase the stock warrant under the same conditions as the equity offering
to maintain its 9.9% interest in the Company. The term of this warrant is for
five years and is exercisable as follows: the first 1/3 shares after 6 months,
an additional 1/3 shares after 12 months, and the final 1/3 after 18 months. The
fair value of the warrants was $900,000 at grant, which has been included in
additional paid-in capital.

NOTE 9: STOCKHOLDERS' EQUITY (CONTINUED)
    In July 1997, the Board of Directors approved the exchange of Common Stock
warrants and nonqualifying stock options held by certain directors for new
Common Stock warrants to purchase 20,256 shares of Common Stock at an exercise
price of $4.70 per shares, the fair market value of the common stock on that
date of exchange. The effect of such exchange reduced the weighted average
exercise price of the warrants and nonqualifying options from $19.70 to $4.70
per share. In November 1997, a director was issued warrants to purchase 750
shares of Common Stock at an exercise price of $14.40 per share. In
February 1998, certain directors exercised their warrants for 13,756 shares of
Common Stock.

    In February 1997, the Company issued 50,000 warrants at $22.50 per share in
conjunction with the $3,500,000 convertible debentures. The value of the
warrants was $850,000 and was recorded as a discount to the debentures. In
August 1997, the 50,000 warrants were exchanged for 35,000 warrants at $5.30 per
share. During 1997, 10,500 warrants were exercised for $56,000.

The Board of Directors of Purchaser and the Board of Directors of Merger Sub
have approved this Agreement. The Board of Directors of Company has approved
this Agreement and has resolved to recommend to the stockholders of Company to
vote in favor of this Agreement;

    NOW, THEREFORE, in consideration of the premises and the mutual covenants
herein contained and for other good and valuable consideration the receipt and
sufficiency of which are hereby acknowledged, Purchaser, Merger Sub and Company
hereby agree as follows:

                                   ARTICLE I
                                   THE MERGER

    1.1  THE MERGER.  At the Effective Time (as defined in Section 1.3 hereof),
in accordance with this Agreement and Delaware Law, Merger Sub shall be merged
with and into Company, the separate existence of Merger Sub (except as may be
continued by operation of law) shall cease, and Company shall continue as the
surviving corporation under the corporate name it possesses immediately prior to
the Effective Time. Company after the Merger is sometimes referred to
hereinafter as the "SURVIVING CORPORATION".

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

    1.3  CONSUMMATION OF THE MERGER.  As soon as is practicable after the
satisfaction or waiver of the conditions set forth in Article VI hereof, the
parties hereto will cause the Merger to be consummated by filing with the

Section 1.3, a closing (the "CLOSING") will be held at the offices of Wilson
Sonsini Goodrich & Rosati, Professional Corporation, 650 Page Mill Road, Palo
Alto, California, 94304 or at such other location as the parties may establish

    1.4  CHARTER; BYLAWS; DIRECTORS AND OFFICERS.  Unless otherwise determined
by Purchaser prior to the Effective Time, the Certificate of Incorporation and
Bylaws of the Surviving Corporation shall be the Certificate of Incorporation

<PAGE>
Time, until thereafter amended as provided therein and under the applicable
provisions of Delaware law. The directors of Merger Sub immediately prior to the
Effective Time will be the initial directors of the Surviving Corporation, and
the officers of Merger Sub immediately prior to the Effective Time will be the
initial officers of the Surviving Corporation, in each case until their
successors are elected and qualified.

                                   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 Purchaser, Merger Sub, Company or
the holder of any of the following securities:

        (a) Each share of Common Stock, $.10 par value per share, of the Company
(the "SHARES") issued and outstanding immediately prior to the Effective Time
(other than Shares to be canceled pursuant to Section 2.1(c) hereof and any
Dissenting Shares (as hereinafter defined)), shall be canceled and extinguished
and be automatically converted into and become a right to receive $5.25 in cash,
without interest (the "MERGER CONSIDERATION"), upon surrender, in the manner
provided in Section 2.4, of the certificate that evidenced the Shares (the
"CERTIFICATE").

        (b) Each Share that is issued and held in the treasury of Company, or
issued and outstanding and owned by Purchaser or any direct or indirect
subsidiary of Purchaser or Company, immediately prior to the Effective Time
shall be canceled and retired, and no payment shall be made with respect
thereto.

        (c) The holders of Dissenting Shares (as defined below), if any, shall
be entitled to payment for such Shares only to the extent permitted by and in
accordance with the applicable provisions of Delaware Law and California Law.

        (d) Each share of Common Stock of Merger Sub issued and outstanding
immediately prior to the Effective Time shall be automatically converted into
shares of the Surviving Corporation.

    2.2  COMPANY STOCK OPTIONS AND RELATED MATTERS.

        (a) At the Effective Time, Purchaser and the Company (or, if
appropriate, any committee of the Board of Directors of the Company
administering the Company's 1993 Stock Option Plan, as amended, 1996 Stock
Option Plan, as amended, 1999 Stock Option Plan or any other employee or
director stock option plan or arrangement of the Company except the Company's
1995 Directors Plan and the Company's 1999 Employee Stock Purchase Plan
(collectively, the "PLANS") shall take such action as may be required to effect
the following provisions of this Section 2.2(a). Subject to the provisions of
Section 16 of the Exchange Act (as hereinafter defined), as of the Effective
Time each option to purchase Shares pursuant to the Plans (a "COMPANY STOCK
OPTION") which is then outstanding shall be assumed by Purchaser and converted
into an option (an "ASSUMED STOCK OPTION") to purchase the number of shares of
Purchaser Common Stock (rounded down to the nearest whole share) equal to (x)
the number of Shares subject to such option multiplied by (y) the ratio
determined by dividing $5.25 by the Average Purchaser Stock Price (as defined
below) for the five (5) consecutive trading day period ending on the second
trading day following the date on which Purchaser and Company issue a press
release announcing this Agreement (the "EXCHANGE RATIO"), at an exercise price
per share of Purchaser Common Stock (rounded up to the nearest penny) equal to
(A) the former exercise price per share of Company Common Stock under such
option immediately prior to the Effective Time divided by (B) the Exchange
Ratio; PROVIDED, HOWEVER, that in the case of any Company Stock Option which is
an "incentive stock option" (as defined in Section 422 of the Code), the
conversion formula shall be adjusted, if necessary, in a manner consistent with
Section 424(a) of the Code. Except as provided above and except as otherwise
provided by the terms of any Company Stock Option, 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 converted Company
Stock Option immediately prior to the Effective Time. As used herein, the
"AVERAGE PURCHASER STOCK

                                      A-2
<PAGE>
PRICE" shall mean the average of the daily closing prices, regular way, of one
share of Purchaser Common Stock (rounded to the nearest thousandth) on the
Nasdaq National Market (as reported in the New York City edition of the Wall
Street Journal, or, if not reported thereby, another nationally recognized
source).

        (b) As soon as practicable after the Effective Time, Purchaser shall
deliver to holders of Company Stock Options appropriate notices setting forth
such holders' rights pursuant to the respective Plans and the agreements
evidencing the grants of such Company Stock Options and stating that such
Company Stock Options and agreements have been assumed by Purchaser and shall
continue in effect on the same terms and conditions (subject to the adjustments
required by this Section 2.2). Purchaser shall comply with the terms of the
Plans and ensure, to the extent required by, and subject to the provisions of,
such Plans, that the Company Stock Options which qualified as incentive stock
options after the Effective Time continue to qualify as incentive stock options
after the Effective Time. Purchaser shall take such actions as are reasonably
necessary for the assumption of the Plans pursuant to this Section 2.2,
including the reservation, issuance and listing of Purchaser Common Stock as is
necessary to effectuate the transactions contemplated by this Section 2.2.
Purchaser shall use reasonable efforts to prepare and file with the Securities
and Exchange Commission (the "SEC") within 30 days after the Effective Time a
registration statement on Form S-8 or other appropriate form with respect to
shares of Purchaser Common Stock subject to the 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.

        (c) The Board of Directors of Company (the "BOARD") shall take all
actions necessary pursuant to the terms of the Company's 1999 Employee Stock
Purchase Plan (the "ESPP") in order to shorten the Offering Periods (as defined
in the ESPP) then in progress such that the New Exercise Date (as defined in the
ESPP) shall occur immediately prior to the Effective Time.

    2.3  DISSENTING SHARES.

        (a) Notwithstanding any provision of this Agreement to the contrary,
holders of Shares which are entitled to dissenter's rights in connection with
the Merger under the applicable provisions of Delaware Law and California Law
(collectively, the "DISSENTING SHARES") shall not be converted into or represent
the right to receive the Merger Consideration. Such stockholders shall be
entitled to receive payment of the fair market value of such Shares held by them
in accordance with the provisions of Delaware Law or California Law, except that
all Dissenting Shares held by stockholders who shall have failed to perfect or
who effectively shall have withdrawn or lost their rights to the payment of fair
market value for such Shares under Delaware Law or California Law shall
thereupon be deemed to have been converted into and to have become exchangeable
for, as of the Effective Time, the right to receive the Merger Consideration,
without any interest thereon, upon surrender, in the manner provided in
Section 2.4, of the certificate or certificates that formerly evidenced such
Shares.

        (b) Company shall give Purchaser (i) prompt notice of any demand for
payment of fair market value received by Company, the withdrawals of any such
demand, and any other instrument served pursuant to Delaware Law or California
Law and received by Company and (ii) the opportunity to direct all negotiations
and proceedings with respect to demands for payment of fair market value under
Delaware Law or California Law. Company shall not, except with the prior written
consent of Purchaser, make any payment with respect to any demands for payment
of fair market value or offer to settle or settle any such demands.

    2.4  EXCHANGE OF CERTIFICATES.

        (a) From and after the Effective Time, a bank or trust company to be
designated by Purchaser (the "EXCHANGE AGENT") shall act as exchange agent in
effecting the exchange of the Merger Consideration for Certificates which, prior
to the Effective Time, represented Shares entitled to payment pursuant to
Section 2.1 hereof. On or before the Effective Time, Purchaser shall deposit
with the Exchange Agent the aggregate Merger Consideration (the "DEPOSIT
AMOUNT") in trust for the benefit of the holders of

                                      A-3
<PAGE>
Certificates. Pending distribution pursuant to this Section 2.4(a) of the
Deposit Amount deposited with the Exchange Agent, Purchaser may direct the
Exchange Agent to invest such Deposit Amount, PROVIDED that such investments
(i) shall be obligations of or guaranteed by the United States of America, in
commercial paper obligations receiving the highest rating from either Moody's
Investors Services, Inc. or Standard & Poor's Corporation, or in certificates of
deposit, bank repurchase agreements or bankers acceptances of commercial banks
with capital exceeding $500,000,000 (collectively "PERMITTED INVESTMENTS") or in
money market funds which are invested solely in Permitted Investments and
(ii) shall have maturities that will not prevent or delay payments to be made
pursuant to this Section 2.4(a). Upon the surrender of each such Certificate and
the issuance and delivery by the Exchange Agent of the Merger Consideration in
exchange therefor, such Certificate shall forthwith be canceled. Until so
surrendered and exchanged, each such Certificate (other than Certificates
representing Shares held by Purchaser or the Company or any direct or indirect
subsidiary of Purchaser or the Company and Dissenting Shares) shall represent
solely the right to receive the Merger Consideration, without interest,
multiplied by the number of Shares represented by such Certificate. Promptly
after the Effective Time (but in no event later than five (5) business days
thereafter), the Exchange Agent shall mail to each record holder of Certificates
which immediately prior to the Effective Time represented Shares a form of
letter of transmittal and instructions for use in surrendering such Certificates
and receiving the Merger Consideration therefor. Upon the surrender to the
Exchange Agent of such an outstanding Certificate together with such letter of
transmittal, duly completed and validly executed in accordance with the
instructions thereto, and such other documents as may be required pursuant to
such instructions, the holder shall receive the Merger Consideration, without
any interest thereon, and such certificate shall be canceled. If any Merger
Consideration is to be paid to a name other than the name in which the
Certificate representing Shares surrendered in exchange therefor is registered,
it shall be a condition to such payment or exchange that the person requesting
such payment or exchange shall pay to the Exchange Agent any transfer or other
taxes required by reason of the payment of such Merger Consideration to a name
other than that of the registered holder of the Certificate surrendered, or such
person shall establish to the satisfaction of the Exchange Agent that such tax
has been paid or is not applicable. Notwithstanding the foregoing, neither the
Exchange Agent nor any party hereto shall be liable to a holder of Shares for
any Merger Consideration delivered to a public official pursuant to applicable
abandoned property laws.

        (b) Purchaser shall not be entitled to the return of any of the Deposit
Amount in the possession of the Exchange Agent relating to the transactions
described in this Agreement until the date which is one year after the Effective
Time. Thereafter, each holder of a Certificate representing a Share may
surrender such Certificate to the Surviving Corporation or Purchaser and
(subject to applicable abandoned property, escheat and similar laws) receive in
exchange therefor the Merger Consideration, without any interest thereon, but
shall have no greater rights against the Surviving Corporation or Purchaser than
may be accorded to general creditors of the Surviving Corporation or Purchaser.

        (c) At and after the Effective Time, the holders of Certificates to be
exchanged for the Merger Consideration pursuant to this Agreement shall cease to
have any rights as to stockholders of the Company except for the right to
surrender such holder's Certificates in exchange for payment of the Merger
Consideration, and after the Effective Time there shall be no transfers on the
stock transfer books of the Surviving Corporation of the Shares which were
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Certificates are presented to the Surviving Corporation or Purchaser or
the Exchange Agent, they shall be canceled and exchanged for the Merger
Consideration, as provided in this Article I, subject to applicable law in the
case of Dissenting Shares.

        (d) The provisions of this Section 2.4 shall also apply to Dissenting
Shares that lose their status as such, except that the obligations of Exchange
Agent under this Section 2.4 shall commence on the date of loss of such status.

    2.5  SUPPLEMENTARY ACTION.  If at any time after the Effective Time, any
further assignments or assurances in law or any other things are necessary or
desirable to vest or to perfect or confirm of record in

                                      A-4
<PAGE>
the Surviving Corporation the title to any property or rights of either the
Company or Merger Sub, or otherwise to carry out the provisions of this
Agreement, the officers and directors of the Surviving Corporation are hereby
authorized and empowered, in the name of and on behalf of the Company and Merger
Sub, to execute and deliver any and all things necessary or proper to vest or to
perfect or confirm title to such property or rights in the Surviving
Corporation, and otherwise to carry out the purposes and provisions of this
Agreement.

                                  ARTICLE III
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

    The Company represents and warrants to Purchaser and Merger Sub that, except
as described in the disclosure letter furnished by the Company to Purchaser

corporation duly organized, validly existing and in good standing under the laws
of the jurisdiction of its incorporation, and has all requisite corporate power
and authority to own, operate and lease its properties and to carry on its
business as it is now being conducted. Each of the Company and its Subsidiaries
is duly qualified as a foreign corporation, and is in good standing, in each
jurisdiction where the character of its properties owned or held under lease or
the nature of its activities makes such qualification necessary except where
such failure would not have a Material Adverse Effect. Section 3.1 of the
Company Disclosure Letter sets forth a list of all Subsidiaries of the Company.
Other than the Company's ownership interest in its Subsidiaries, the Company has
no direct or indirect equity or related interest in any partnership,
corporation, joint venture, business association or other entity.

        (b) In this Agreement, (i) a "SUBSIDIARY" means any corporation more
than fifty percent (50%) of whose outstanding voting securities are, or any
partnership, joint venture or other entity more than fifty percent (50%) of
whose total equity interest is, directly or indirectly owned by Purchaser or the
Company or such other entity, as the case may be, (ii) any reference to any
event, change or effect being "material" with respect to any entity or group of
entities means any event, change or effect which is material to the businesses,
assets, results of operations or financial conditions of such entity or group of

or group of entities, any change in or effect on the business, properties or
assets of such entity or group of entities that is materially adverse to the
business, properties, assets, results of operations or financial condition of
such entity or group of entities, taken as a whole.

    3.2  CERTIFICATE OF INCORPORATION AND BYLAWS.  The Company shall furnish to
Purchaser within twenty one (21) days after the date of this Agreement complete
and correct copies of the Certificate of Incorporation (or other charter
document) and Bylaws of the Company and similar governing instruments of each of
its Subsidiaries, and in each case such copies shall be accurate and complete as
of the date of this Agreement.

    3.3  CAPITALIZATION OF THE COMPANY.

        (a) The authorized capital stock of the Company consists of (i)
2,000,000 shares of preferred stock, of which (A) 1,000,000 shares have been
designated Series B Preferred Stock, of which 18,003 are issued and outstanding
(the "SERIES B PREFERRED"), (B) 300,000 shares of which have been designated
Series C Preferred Stock, all of which are issued and outstanding (the
"SERIES C PREFERRED"), and (C) 420,000 shares of which have been designated

<PAGE>
outstanding (the "SERIES C-1 PREFERRED") but up to all of which are issuable
upon conversion of that certain Convertible Promissory Note dated May 25, 1999,
issued to Purchaser (the "CONVERTIBLE PROMISSORY NOTE"); and (ii) 65,000,000
shares of common stock, par value $.10 per share, of which (A) 4,662,464 Shares
are issued and outstanding, (B) 165,158 shares of common stock are reserved for
issuance pursuant to the 1993 Stock Option Plan, as amended (of which options to
purchase 157,338 Shares are outstanding as of the date of this Agreement and
options to purchase 7,820 Shares remain available for future grant), (C) 20,000
shares of common stock are reserved for issuance pursuant to the 1995 Directors
Plan (of which options to purchase 2,250 Shares are outstanding as of the date
of this Agreement and options to purchase 17,750 Shares remain available for
future grant), (D) 198,292 shares of common stock are reserved for issuance
pursuant to the 1996 Stock Option Plan, as amended (of which options to purchase

Plans and (ii) the Company's right to repurchase any unvested Shares under the
Plans, there are no other options, warrants, calls, rights commitments or
agreements of any character to which the Company is a party or by which it is
bound obligating the Company to issue, sell, deliver, repurchase, or redeem or
cause to be issued, sold, delivered, repurchased or redeemed any shares of
capital stock of, or equity interests in, the Company. All outstanding Shares
are, and all Shares subject to issuance as aforesaid, upon issuance on the terms
and conditions specified in the instruments pursuant to which they are issuable,
will be, duly authorized, validly issued, fully paid and nonassessable and free
of preemptive rights or rights of first refusal. None of the Company or any of
its Subsidiaries is required to redeem, repurchase or otherwise acquire shares
of capital stock of the Company or any of its Subsidiaries, respectively, as a
result of the transactions contemplated by this Agreement. The Company has no
stockholder rights plan or agreement in force providing for the issuance to
holders of Shares of rights to purchase or receive stock, cash or other assets
upon the acquisition or proposed acquisition of Shares by a person or entity (a
"RIGHTS PLAN"), nor has the Company's Board of Directors or stockholders ever
adopted a Rights Plan.

        (b) The Company owns all of the outstanding capital stock of its
Subsidiaries free and clear of any liens, security interests, pledges,
agreements, claims, charges or encumbrances of any nature whatsoever. There are
no voting trusts or other agreements or understandings to which the Company or
any of its Subsidiaries is a party or by which the Company or any of its
Subsidiaries may be bound with respect to the voting of the capital stock of the
Company or any of the Company's Subsidiaries.

    3.4  CORPORATE POWER, AUTHORIZATION AND ENFORCEABILITY.  The Company has
full corporate power and authority to enter into this Agreement and to perform
its obligations hereunder and to consummate all the transactions contemplated
hereby. The execution and delivery of this Agreement by the Company, the
performance by the Company of its obligations hereunder and the consummation by
the Company of the transactions contemplated hereby have been duly and validly
authorized by the Company's Board of Directors and no other corporate action on
the part of the Company is necessary to authorize this Agreement or to
consummate the transactions contemplated hereby (other than, with respect to the
Merger, the approval and adoption of this Agreement by stockholders holding a
majority of the outstanding Shares). All corporate actions necessary to ensure
that the provisions of Section 203 of Delaware Law shall not be applicable to
the consummation of the transactions contemplated by this Agreement have been
taken prior to the execution of this Agreement. This Agreement has been duly
executed and delivered by the Company and (subject to obtaining any necessary
approval of its stockholders) is a legal, valid and binding obligation of the
Company, enforceable against the Company in accordance with its terms.

        (a) Assuming satisfaction of any applicable requirements referred to in
Section 3.5(b) below, the execution and delivery by the Company of this
Agreement, the compliance by the Company with the provisions hereof and the
consummation by the Company of the transactions contemplated hereby will not
conflict with or violate any statute, law, ordinance, rule, regulation, order,
writ, judgment, award, injunction, decree or ruling applicable to the Company or
any of its Subsidiaries or any of their respective properties, or conflict with,
violate or result in any breach of or constitute a default (or an event which

others any rights of termination, amendment, cancellation or acceleration of, or
the loss of a benefit under, or result in the creation of a lien, security
interest, charge or encumbrance on any of the properties or assets of the
Company or any of its Subsidiaries pursuant to (i) the Certificate of
Incorporation (or other charter document) or Bylaws of the Company or the
similar governing instruments of any of its Subsidiaries or (ii) any contract,
lease, agreement, note, bond, mortgage, indenture, deed of trust, or other
instrument or obligation, or any license, authorization, permit, certificate or
other franchise, other than such conflicts, violations, breaches, defaults,
losses, rights of termination, amendment, cancellation or acceleration, liens,
security interests, charges or encumbrances as to which requisite waivers have
been obtained.

        (b) Other than in connection with or in compliance with the provisions
of Delaware Law, California Law, the Securities Exchange Act of 1934, as amended
(the "EXCHANGE ACT"), or the "takeover" or "blue sky" laws of various states,
(i) no notice, report, registration, declaration or other filing with any
federal, state or local government, court, administrative agency or commission
or other governmental authority or instrumentality, domestic or foreign
(collectively, "GOVERNMENTAL ENTITIES"), is required in connection with the
execution or delivery of this Agreement by the Company or the performance by the
Company of its obligations hereunder or the consummation by the Company of the
transactions contemplated by this Agreement and (ii) no waiver, consent,
approval, order or authorization of any Governmental Entity is required to be
obtained in connection with the execution or delivery of this Agreement by the
Company or the performance by the Company of its obligations hereunder or the

    3.6  SEC REPORTS; FINANCIAL STATEMENTS.

        (a) The Company has filed in a timely manner all forms, reports and
documents required to be filed with the SEC since August 14, 1998, and has made
available to Purchaser all such forms, reports and documents. All such required
forms, reports and documents (including those that the Company may file
subsequent to the date hereof) are referred to herein as the "SEC REPORTS." As

the requirements of the Securities Act of 1933, as amended (the "SECURITIES
ACT"), or the Exchange Act, as the case may be, and the rules and regulations of
the SEC thereunder applicable to such the SEC Reports, and (ii) did not at the
time they were filed (or if amended or superseded by a filing prior to the date
of this Agreement, then on the date of such filing) contain any untrue statement
of a material fact or omit to state a material fact required to be stated
therein or necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading. None of the
Company's Subsidiaries is required to file any forms, reports or other documents
with the SEC.

                                      A-7
<PAGE>
        (b) Each of the consolidated financial statements (including, in each
case, any related notes thereto) contained in the SEC Reports (the "FINANCIAL

the Closing, (x) complied as to form in all material respects with the published
rules and regulations of the SEC with respect thereto, (y) was prepared in
accordance with generally accepted accounting principles ("GAAP") applied on a
consistent basis throughout the periods involved (except as may be indicated in
the notes thereto or, in the case of unaudited interim financial statements, as
may be permitted by the SEC on Form 10-Q, 8-K or any successor form under the
Exchange Act) and (z) fairly presented the consolidated financial position of

adjustments. The balance sheet of the Company contained in the SEC Reports as of
March 31, 2000 is hereinafter referred to as the "COMPANY BALANCE SHEET." Except
as disclosed in the Financial Statements, since the date of the Company Balance
Sheet neither the Company nor any of its Subsidiaries has any liabilities
(absolute, accrued, contingent or otherwise) of a nature required to be
disclosed on a balance sheet or in the related notes to the consolidated
financial statements prepared in accordance with GAAP which are, individually or
in the aggregate, material to the business, results of operations or financial
condition of the Company and its Subsidiaries taken as a whole, except
liabilities (i) provided for in the Company Balance Sheet, or (ii) incurred
since the date of the Company Balance Sheet in the ordinary course of business
consistent with past practices and immaterial in the aggregate and liabilities
incurred in connection with this Agreement.

        (c) The Company shall furnish to Purchaser within twenty one (21) days
after the date of this Agreement a complete and correct copy of any amendments
or modifications, which have not yet been filed with the SEC but which are
required to be filed, to agreements, documents or other instruments which
previously had been filed by the Company with the SEC pursuant to the Securities
Act or the Exchange Act.

    3.7  NO DEFAULT.  As of the date of this Agreement, neither the Company nor
any of its Subsidiaries is in default or violation (and no event has occurred
which with or without notice, the lapse of time or the happening or occurrence
of any other event would constitute a default or violation) of any term,
condition or provision of (i) its Certificate of Incorporation or Bylaws (or
similar governing instruments), or (ii) any material contract, lease, agreement,
license, note, bond, mortgage, indenture, deed of trust or other instrument or
obligation to which the Company or any of its Subsidiaries is a party or by
which the Company or its Subsidiaries or any of their properties or assets may

breach thereof or default thereunder).

    3.8  COMPLIANCE WITH LAW.  Except as disclosed in the SEC Reports, each of
the Company and its Subsidiaries is in compliance, and has conducted its
respective businesses so as to comply with all statutes, laws, ordinances,
rules, regulations, permits and approvals applicable to its operations. Except
as disclosed in the SEC Reports, no investigation or review by any Governmental
Entity with respect to the Company, any of its Subsidiaries or any property
owned or leased by the Company or any of its Subsidiaries is pending or, to the
knowledge of the Company, threatened. The Company and its Subsidiaries have all
permits, authorizations, licenses and franchises from Governmental Entities
required to conduct their businesses as now being conducted.

    3.9  ABSENCE OF CERTAIN CHANGES.  Except as contemplated by this Agreement
or as disclosed in the SEC Reports, the Company's financial statements for the
fiscal year ended December 31, 1999, or the Company Balance Sheet, since the
date of the Company Balance Sheet (the date of the Company Balance Sheet is
referred to as the "BALANCE SHEET DATE"), the Company and its Subsidiaries have
conducted their business in the ordinary course consistent with past practice
and have not taken any of the actions set forth in paragraphs (a) through (m) of

                                      A-8
<PAGE>
reasonably be expected to have a Material Adverse Effect including any material
change by the Company in its accounting methods, principles or practices, except
as required by changes in GAAP.

    3.10  NO UNDISCLOSED LIABILITIES.  Except for liabilities and obligations
recognized or disclosed in the Financial Statements or disclosed in the SEC
Reports or incurred since the Balance Sheet Date in the ordinary course of
business consistent with past practices, neither the Company nor any of its
Subsidiaries has any liabilities or obligations of any nature whatsoever
(whether absolute, accrued, fixed, contingent, liquidated, unliquidated or
otherwise) required by GAAP to be recognized or disclosed on a consolidated
balance sheet of the Company and its Subsidiaries or in the notes thereto.

    3.11  LITIGATION.  Except as set forth in the SEC Reports, there is no

Subsidiaries or any of their respective properties and there is no judgment,
decree, writ, injunction, award, ruling or order of any Governmental Entity or
arbitrator outstanding against or, to the knowledge of the Company, threatened
against or affecting the Company or any of its Subsidiaries. The Company shall
make available to Purchaser within twenty one (21) days after the date of this
Agreement correct and complete copies of all correspondence prepared by its
counsel for the Company's auditors in connection with the last two completed
audits of the Company's financial statements and any such correspondence since
the date of the last such audit. As of the date of this Agreement, there are no
actions, suits or proceedings pending or, to the knowledge of the Company,
threatened against the Company arising out of or in any way related to this
Agreement, the Merger or any of the transactions contemplated hereby or thereby.

    3.12  ERISA.

        (a) Section 3.12 of the Company Disclosure Letter identifies each
"employee benefit plan," as defined in Section 3(3) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), and all other written or
formal plans or agreements involving direct or indirect compensation (including
any employment agreements entered into between the Company or any of its
Subsidiaries and any employee or former employee of the Company or any of its
Subsidiaries, but excluding worker's compensation, unemployment compensation and
other government-mandated programs) currently or previously maintained,
contributed to or entered into by the Company or any of its Subsidiaries or any
ERISA Affiliate thereof for the benefit of any employee or former employee of
the Company or any of its Subsidiaries under which the Company or any of its
Subsidiaries or any ERISA Affiliate thereof has any present or future obligation
or liability (collectively, the "COMPANY EMPLOYEE PLANS"). For purposes of this
Section 3.12, "ERISA AFFILIATE" shall mean any entity which is a member of
(i) a "controlled group of corporations," as defined in Section 414(b) of the
Internal Revenue Code of 1986, as amended (the "CODE"), (ii) a group of entities
under "common control," as defined in Section 414(c) of the Code or (iii) an
"affiliated service group," as defined in Section 414(m) of the Code or treasury
regulations promulgated under Section 414(o) of the Code, any of which includes
the Company or any of its Subsidiaries. The only Company Employee Plans which
individually or collectively would constitute an "employee pension benefit
plan," as defined in Section 3(2) of ERISA (collectively, the "COMPANY PENSION
PLANS"), are identified as such in Section 3.12 of the Company Disclosure
Letter.

        (b) No Company Pension Plan is subject to Title IV of ERISA, Part 3 of
Title I of ERISA or Section 412 of the Code. No Company Pension Plan constitutes
or has since the enactment of ERISA constituted a "multiemployer plan," as
defined in Section 3(37) of ERISA. No "prohibited transaction," as defined in
Section 406 of ERISA or Section 4975 of the Code, has occurred with respect to
any Company Employee Plan which is covered by Title I of ERISA, excluding
transactions effected pursuant to a statutory or administrative exemption.
Nothing done or omitted to be done and no transaction or holding of any asset
under or in connection with any Company Employee Plan has or is likely to make
the Company or any of its Subsidiaries or any officer or director thereof
subject to any material liability under Title I of ERISA or liable for any
material tax pursuant to Section 4975 of the Code.

                                      A-9
<PAGE>
        (c) Each Company Pension Plan which is intended to be qualified under
Section 401(a) of the Code is so qualified and has been so qualified during the
period from its adoption to date, except to the extent that the requirements for
qualification may be satisfied by adopting retroactive amendments under Section
401(b) of the Code and the regulations thereunder or under Section 1140 of the
Tax Reform Act of 1986. Each trust forming a part of a Company Pension Plan is
exempt from tax pursuant to Section 501(a) of the Code. Each Company Pension
Plan has been maintained substantially in compliance with its terms and with the
applicable requirements of ERISA and the Code.

        (d) Section 3.12 of the Company Disclosure Letter identifies each
employment, severance or other similar contract, arrangement or policy and each
plan or arrangement (written or oral) providing for insurance coverage
(including any self-insured arrangements), vacation benefits, severance or
severance-type benefits, disability benefits, death benefits, hospitalization
benefits, retirement benefits, deferred compensation, profit-sharing, bonuses,
stock options, stock purchase, phantom stock, stock appreciation or other forms
of incentive compensation or post-retirement insurance, compensation or benefits
which (i) is not a Company Employee Plan, (ii) is entered into, maintained or
contributed to, as the case may be, by the Company or any of its Subsidiaries,
and (iii) covers any employee or former employee of the Company or any of its
Subsidiaries. Such contracts, plans and arrangements as are described in this
Section 3.12 are herein referred to collectively as the "COMPANY BENEFIT
ARRANGEMENTS." Each Company Benefit Arrangement has been maintained in
substantial compliance with its terms and with the requirements prescribed by
any and all statutes, orders, rules and regulations which are applicable to such
Company Benefit Arrangements.

        (e) Except as set forth in Section 3.12 of the Company Disclosure
Letter, there has been no amendment to, written interpretation or announcement
(whether or not written) by the Company or any of its Subsidiaries relating to,
or change in employee participation or coverage under, any Company Employee Plan
or Company Benefit Arrangement which would increase materially the expense of
maintaining such Company Employee Plan or Company Benefit Arrangement above the
level of the expense incurred in respect thereof for the fiscal year ended
December 31, 1999.

Statement and form of proxy cleared by the Commission as promptly as
practicable, and promptly thereafter shall mail the definitive Proxy Statement
and form of proxy to stockholders of the Company. The term "PROXY STATEMENT"

if any, similarly filed and mailed. The information provided and to be provided
by Purchaser and the Company, respectively, for use in Proxy Statement shall, on
the date the Proxy Statement is first mailed to the Company's stockholders and
on the date of the Special Meeting (as hereinafter defined), not contain an
untrue statement of a material fact or omit to state any material fact necessary
in order to make such information, in light of the circumstances under which it

Agreement) or similar transactions involving the Company or any of its
Subsidiaries (an "ACQUISITION PROPOSAL"). The Company shall promptly inform

third party making such inquiry) which it may receive in respect of an
Acquisition Proposal and furnish to Purchaser a copy of any such written
inquiry.

date of this Agreement, participate in discussions or negotiations with, or
furnish information with respect to the Company pursuant to a confidentiality
agreement substantially similar to that then in effect between the Company and
Purchaser, to, any person. In addition, following the receipt of an Acquisition
Proposal, which the Company's Board of Directors determines in good faith to be
more favorable to the Company's stockholders than the Merger (a "SUPERIOR
PROPOSAL"), the Company may terminate this Agreement under Section
7.1(d)(i) and accept such Superior Proposal, and the Board of Directors of the
Company may approve or recommend (and, in connection therewith withdraw or
modify its approval or recommendation of this Agreement or the Merger). Nothing
contained in this Section 5.5(b) shall prohibit the Company or its Board of
Directors from making any disclosure to the Company's stockholders that, in the

Purchaser and Purchaser shall give prompt notice in writing to the Company, of
(i) the occurrence, or failure to occur, of any event which occurrence or
failure would be likely to cause any representation or warranty contained in
this Agreement to be untrue or inaccurate in any material respect at any time

failure of the Company, Merger Sub, Purchaser, as the case may be, or of any
officer, director, employee or agent thereof, to comply with or satisfy any

representations or warranties of the parties or the conditions to the
obligations of the parties hereunder.

        (b) The Company shall give prompt notice in writing (which notice shall

and agents of the Company as provided in the Company's Certificate of
Incorporation and Bylaws or otherwise, in each case in effect on the date of

least the same extent as such persons are currently permitted to be indemnified

Board of Directors
GateField Corporation
47436 Fremont Blvd.
Fremont, CA 94538

Gentlemen:

    We understand that Gatefield Corporation ("Gatefield") and Actel Corporation
("Actel") propose to enter into an Agreement and Plan of Merger (the "Merger
Agreement") whereby a wholly-owned subsidiary of Actel will be merged with and
into GateField and GateField will become a wholly-owned subsidiary of Actel (the
"Merger"). The terms of the Merger will be set forth more fully in the Merger
Agreement.

    Pursuant to the proposed Merger Agreement, we understand that at the
Effective Time (as defined in the Merger Agreement) the issued and outstanding
shares of common stock, par $0.10 par value per share, of GateField ("GateField
Common Stock") will be converted into the right to receive $5.25 per share in
cash (the "Consideration").

    You have asked us to advise you as to the fairness, from a financial point
of view, to the holders of GateField Common Stock (other than Actel and its
affiliates) of the Consideration to be received by such holders in the Merger.
Needham & Company, Inc., as part of its investment banking business, is
regularly engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, secondary
distributions of securities, private placements and other purposes. We have been
engaged by GateField as financial advisor to render this opinion in connection
with the Merger and will receive a fee for our services, none of which is
contingent on the consummation of the Merger. In addition, GateField has agreed
to indemnify us for certain liabilities arising from our role as financial
advisor and out of the rendering of this opinion.

    For purposes of this opinion we have, among other things: (i) reviewed a
draft of the Merger Agreement dated May 12, 2000; (ii) reviewed certain publicly
available information concerning GateField and certain other relevant financial
and operating data of GateField furnished to us by GateField; (iii) held
discussions with members of management of GateField concerning the current and
future business prospects of GateField; (iv) reviewed and discussed with the
management of GateField certain financial forecasts and projections prepared by
such management; (v) reviewed the historical stock prices and trading volumes of
GateField Common Stock; (vi) compared certain publicly available financial data
of companies whose securities are traded in the public markets and that we
deemed generally relevant to similar data for GateField; (vii) reviewed the
financial terms of certain other business combinations that we deemed generally
relevant; and (viii) performed and/or considered such other studies, analyses,
inquiries and investigations as we deemed appropriate.

    In connection with our review and in arriving at our opinion, we have
assumed and relied on the accuracy and completeness of all of the financial and
other information reviewed by us for purposes of this opinion and have neither
attempted to verify independently nor assumed responsibility for verifying any
of such information. In addition, we have assumed, with your consent, that
(i) any material liabilities (contingent or otherwise, known or unknown) of
GateField are as set forth in the financial statements of GateField and
(ii) the terms set forth in the executed Merger Agreement will not differ
materially from the proposed terms provided to us in the draft Merger Agreement
dated May 12, 2000. With respect to GateField's financial forecasts provided to
us by its management, we have assumed for purposes of our opinion that such
forecasts have been reasonably prepared on bases reflecting the best currently
available estimates and judgments of such management, at the time of
preparation, of the future operating and financial performance of GateField. We
express no opinion with respect to such forecasts or the

                                      B-1

assumptions on which they were based. We have not assumed any responsibility for
or made or obtained any independent evaluation, appraisal or physical inspection
of the assets or liabilities of GateField. Further, our opinion is based on
economic, monetary and market conditions as they exist and can be evaluated as
of the date hereof. Our opinion as expressed herein is limited to the fairness,
from a financial point of view, to the holders of GateField Common Stock (other
than Actel and its affiliates) of the Consideration to be received by such
holders in the Merger and does not address GateField's underlying business
decision to engage in the Merger or the consideration to be received by any
individual stockholder. Our opinion does not constitute a recommendation to any
stockholder of GateField as to how such stockholder should vote on the proposed
Merger. We are not expressing any opinion as to the prices at which the
GateField Common Stock will actually trade at any time.

    In the ordinary course of our business, we may actively trade the equity
securities of GateField and Actel for our own account or for the accounts of
customers and, accordingly, may at any time hold a long or short position in
such securities.

    This letter and the opinion expressed herein are provided at the request and
for the information of the Board of Directors of GateField and may not be quoted
or referred to or used for any purpose without our prior written consent, except
that this letter may be disclosed in connection with any information statement
or proxy statement used in connection with the Merger so long as this letter is
quoted in full in such information statement or proxy statement.

    Based upon and subject to the foregoing, it is our opinion that as of the
date hereof the Consideration to be received by the holders of GateField Common
Stock (other than Actel and its affiliates) in the Merger is fair to such
holders from a financial point of view.

                                          Very truly yours,

                                          NEEDHAM & COMPANY, INC.

                        DELAWARE GENERAL CORPORATION LAW
                         SECTION 262. APPRAISAL RIGHTS

    (a) Any stockholder of a corporation of this State who holds shares of stock
on the date of the making of a demand pursuant to subsection (d) of this section
with respect to such shares, who continuously holds such shares through the
effective date of the merger or consolidation, who has otherwise complied with
subsection (d) of this section and who has neither voted in favor of the merger
or consolidation nor consented thereto in writing pursuant to Section  228 of
this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a nonstock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation; and the
words "depository receipt" mean a receipt or other instrument issued by a
depository representing an interest in one or more shares, or fractions thereof,
solely of stock of a corporation, which stock is deposited with the depository.

    (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to Section  251 (other than a merger effected pursuant to
Section  251(g) of this title), Section  252, Section  254, Section  257,
Section  258, Section  263 or Section  264 of this title:

        (1) Provided, however, that no appraisal rights under this section shall
    be available for the shares of any class or series of stock, which stock, or
    depository receipts in respect thereof, at the record date fixed to
    determine the stockholders entitled to receive notice of and to vote at the
    meeting of stockholders to act upon the agreement of merger or
    consolidation, were either (i) listed on a national securities exchange or
    designated as a national market system security on an interdealer quotation
    system by the National Association of Securities Dealers, Inc. or (ii) held
    of record by more than 2,000 holders; and further provided that no appraisal
    rights shall be available for any shares of stock of the constituent
    corporation surviving a merger if the merger did not require for its
    approval the vote of the stockholders of the surviving corporation as
    provided in subsection (f) of Section  251 of this title.

        (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
    under this section shall be available for the shares of any class or series
    of stock of a constituent corporation if the holders thereof are required by
    the terms of an agreement of merger or consolidation pursuant to Section
    Section  251, 252, 254, 257, 258, 263 and 264 of this title to accept for
    such stock anything except:

           a.  Shares of stock of the corporation surviving or resulting from
       such merger or consolidation, or depository receipts in respect thereof;

           b.  Shares of stock of any other corporation, or depository receipts
       in respect thereof, which shares of stock (or depository receipts in
       respect thereof) or depository receipts at the effective date of the
       merger or consolidation will be either listed on a national securities
       exchange or designated as a national market system security on an
       interdealer quotation system by the National Association of Securities
       Dealers, Inc. or held of record by more than 2,000 holders;

           c.  Cash in lieu of fractional shares or fractional depository
       receipts described in the foregoing subparagraphs a. and b. of this
       paragraph; or

           d.  Any combination of the shares of stock, depository receipts and
       cash in lieu of fractional shares or fractional depository receipts
       described in the foregoing subparagraphs a., b. and c. of this paragraph.

                                      C-1

        (3) In the event all of the stock of a subsidiary Delaware corporation
    party to a merger effected under Section  253 of this title is not owned by
    the parent corporation immediately prior to the merger, appraisal rights
    shall be available for the shares of the subsidiary Delaware corporation.

    (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d)
and (e) of this section, shall apply as nearly as is practicable.

    (d) Appraisal rights shall be perfected as follows:

        (1) If a proposed merger or consolidation for which appraisal rights are
    provided under this section is to be submitted for approval at a meeting of
    stockholders, the corporation, not less than 20 days prior to the meeting,
    shall notify each of its stockholders who was such on the record date for
    such meeting with respect to shares for which appraisal rights are available
    pursuant to subsection (b) or (c) hereof that appraisal rights are available
    for any or all of the shares of the constituent corporations, and shall
    include in such notice a copy of this section. Each stockholder electing to
    demand the appraisal of such stockholder's shares shall deliver to the
    corporation, before the taking of the vote on the merger or consolidation, a
    written demand for appraisal of such stockholder's shares. Such demand will
    be sufficient if it reasonably informs the corporation of the identity of
    the stockholder and that the stockholder intends thereby to demand the
    appraisal of such stockholder's shares. A proxy or vote against the merger
    or consolidation shall not constitute such a demand. A stockholder electing
    to take such action must do so by a separate written demand as herein
    provided. Within 10 days after the effective date of such merger or
    consolidation, the surviving or resulting corporation shall notify each
    stockholder of each constituent corporation who has complied with this
    subsection and has not voted in favor of or consented to the merger or
    consolidation of the date that the merger or consolidation has become
    effective; or

        (2) If the merger or consolidation was approved pursuant to Section
    228 or Section  253 of this title, each consitutent corporation, either
    before the effective date of the merger or consolidation or within ten days
    thereafter, shall notify each of the holders of any class or series of stock
    of such constitutent corporation who are entitled to appraisal rights of the
    approval of the merger or consolidation and that appraisal rights are
    available for any or all shares of such class or series of stock of such
    constituent corporation, and shall include in such notice a copy of this
    section; provided that, if the notice is given on or after the effective
    date of the merger or consolidation, such notice shall be given by the
    surviving or resulting corporation to all such holders of any class or
    series of stock of a constituent corporation that are entitled to appraisal
    rights. Such notice may, and, if given on or after the effective date of the
    merger or consolidation, shall, also notify such stockholders of the
    effective date of the merger or consolidation. Any stockholder entitled to
    appraisal rights may, within 20 days after the date of mailing of such
    notice, demand in writing from the surviving or resulting corporation the
    appraisal of such holder's shares. Such demand will be sufficient if it
    reasonably informs the corporation of the identity of the stockholder and
    that the stockholder intends thereby to demand the appraisal of such
    holder's shares. If such notice did not notify stockholders of the effective
    date of the merger or consolidation, either (i) each such constitutent
    corporation shall send a second notice before the effective date of the
    merger or consolidation notifying each of the holders of any class or series
    of stock of such constitutent corporation that are entitled to appraisal
    rights of the effective date of the merger or consolidation or (ii) the
    surviving or resulting corporation shall send such a second notice to all
    such holders on or within 10 days after such effective date; provided,
    however, that if such second notice is sent more than 20 days following the
    sending of the first notice, such second notice need only be sent to each
    stockholder who is entitled to appraisal rights and who has demanded
    appraisal of such holder's shares in accordance with this subsection. An
    affidavit of the

    secretary or assistant secretary or of the transfer agent of the corporation
    that is required to give either notice that such notice has been given
    shall, in the absence of fraud, be prima facie evidence of the facts stated
    therein. For purposes of determining the stockholders entitled to receive
    either notice, each constitutent corporation may fix, in advance, a record
    date that shall be not more than 10 days prior to the date the notice is
    given, provided , that if the notice is given on or after the effective date
    of the merger or consolidation, the record date shall be such effective
    date. If no record date is fixed and the notice is given prior to the
    effective date, the record date shall be the close of business on the day
    next preceding the day on which the notice is given.

    (e) Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied with
subsections (a) and (d) hereof and who is otherwise entitled to appraisal
rights, may file a petition in the Court of Chancery demanding a determination
of the value of the stock of all such stockholders. Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger or
consolidation, any stockholder shall have the right to withdraw such
stockholder's demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
such stockholder's written request for such a statement is received by the
surviving or resulting corporation or within 10 days after expiration of the
period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.

    (f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in Chancery
in which the petition was filed a duly verified list containing the names and
addresses of all stockholders who have demanded payment for their shares and
with whom agreements as to the value of their shares have not been reached by
the surviving or resulting corporation. If the petition shall be filed by the
surviving or resulting corporation, the petition shall be accompanied by such a
duly verified list. The Register in Chancery, if so ordered by the Court, shall
give notice of the time and place fixed for the hearing of such petition by
registered or certified mail to the surviving or resulting corporation and to
the stockholders shown on the list at the addresses therein stated. Such notice
shall also be given by 1 or more publications at least 1 week before the day of
the hearing, in a newspaper of general circulation published in the City of
Wilmington, Delaware or such publication as the Court deems advisable. The forms
of the notices by mail and by publication shall be approved by the Court, and
the costs thereof shall be borne by the surviving or resulting corporation.

    (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

    (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion,

                                      C-3
<PAGE>
permit discovery or other pretrial proceedings and may proceed to trial upon the
appraisal prior to the final determination of the stockholder entitled to an
appraisal. Any stockholder whose name appears on the list filed by the surviving
or resulting corporation pursuant to subsection (f) of this section and who has
submitted such stockholder's certificates of stock to the Register in Chancery,
if such is required, may participate fully in all proceedings until it is
finally determined t hat such stockholder is not entitled to appraisal rights
under this section.

    (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

    (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

    (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or other distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however, that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation, either
within 60 days after the effective date of the merger or consolidation as
provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court
of Chancery shall be dismissed as to any stockholder without the approval of the
Court, and such approval may be conditioned upon such terms as the Court deems
just.

    (l) The shares of the surviving or resulting corporation to which the shares
of such objecting stockholders would have been converted had they assented to
the merger or consolidation shall have the status of authorized and unissued
shares of the surviving or resulting corporation.

                              SECTION 1300 ET SEQ.

Section  1300. Shareholder in short-form merger; Purchase at fair market value;
"Dissenting shares"; "Dissenting shareholder"

    (a) If the approval of the outstanding shares (Section 152) of a corporation
is required for a reorganization under subdivisions (a) and (b) or
subdivision (e) or (f) of Section 1201, each shareholder of the corporation
entitled to vote on the transaction and each shareholder of a subsidiary
corporation in a short-form merger may, by complying with this chapter, require
the corporation in which the shareholder holds shares to purchase for cash at
their fair market value the shares owned by the shareholder which are dissenting
shares as defined in subdivision (b). The fair market value shall be determined
as of the day before the first announcement of the terms of the proposed
reorganization or short-form merger, excluding any appreciation or depreciation
in consequence of the proposed action, but adjusted for any stock split, reverse
stock split, or share dividend which becomes effective thereafter.

    (b) As used in this chapter, "dissenting shares" means shares which come
within all of the following descriptions:

        (1) Which were not immediately prior to the reorganization or short-form
    merger either (A) listed on any national securities exchange certified by
    the Commissioner of Corporations under subdivision (o) of Section 25100 or
    (B) listed on the National Market System of the NASDAQ Stock Market, and the
    notice of meeting of shareholders to act upon the reorganization summarizes
    this section and Sections 1301, 1302, 1303 and 1304; provided, however, that
    this provision does not apply to any shares with respect to which there
    exists any restriction on transfer imposed by the corporation or by any law
    or regulation; and provided, further, that this provision does not apply to
    any class of shares described in subparagraph (A) or (B) if demands for
    payment are filed with respect to 5 percent or more of the outstanding
    shares of that class.

        (2) Which were outstanding on the date for the determination of
    shareholders entitled to vote on the reorganization and (A) were not voted
    in favor of the reorganization or, (B) if described in subparagraph (A)
    or (B) of paragraph (1)(without regard to the provisos in that paragraph),
    were voted against the reorganization, or which were held of record on the
    effective date of a short-form merger; provided, however, that
    subparagraph (A) rather than subparagraph (B) of this paragraph applies in
    any case where the approval required by Section 1201 is sought by written
    consent rather than at a meeting.

        (3) Which the dissenting shareholder has demanded that the corporation
    purchase at their fair market value, in accordance with Section 1301.

        (4) Which the dissenting shareholder has submitted for endorsement, in
    accordance with Section 1302.

    (c) As used in this chapter, "dissenting shareholder" means the recordholder
of dissenting shares and includes a transferee of record.

Section 1301. Notice to holder of dissenting shares of reorganization approval;
Demand for purchase of shares; Contents of demand

    (a) If, in the case of a reorganization, any shareholders of a corporation
have a right under Section 1300, subject to compliance with paragraphs (3)
and (4) of subdivision (b) thereof, to require the corporation to purchase their
shares for cash, such corporation shall mail to each such shareholder a notice
of the approval of the reorganization by its outstanding shares (Section 152)
within 10 days after the date of such approval, accompanied by a copy of
Sections 1300, 1302, 1303, 1304 and this section, a statement of the price
determined by the corporation to represent the fair market value of the
dissenting shares, and a

                                      D-1
<PAGE>
brief description of the procedure to be followed if the shareholder desires to
exercise the shareholder's right under such sections. The statement of price
constitutes an offer by the corporation to purchase at the price stated any
dissenting shares as defined in subdivision (b) of Section 1300, unless they
lose their status as dissenting shares under Section 1309.

    (b) Any shareholder who has a right to require the corporation to purchase
the shareholder's shares for cash under Section 1300, subject to compliance with
paragraphs (3) and (4) of subdivision (b) thereof, and who desires the
corporation to purchase such shares shall make written demand upon the
corporation for the purchase of such shares and payment to the shareholder in
cash of their fair market value. The demand is not effective for any purpose
unless it is received by the corporation or any transfer agent thereof (1) in
the case of shares described in clause (i) or (ii) of paragraph (1) of
subdivision (b) of Section 1300 (without regard to the provisos in that
paragraph), not later than the date of the shareholders' meeting to vote upon
the reorganization, or (2) in any other case within 30 days after the date on
which the notice of the approval by the outstanding shares pursuant to
subdivision (a) or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder.

    (c) The demand shall state the number and class of the shares held of record
by the shareholder which the shareholder demands that the corporation purchase
and shall contain a statement of what such shareholder claims to be the fair
market value of those shares as of the day before the announcement of the
proposed reorganization or short-form merger. The statement of fair market value
constitutes an offer by the shareholder to sell the shares at such price.

Section  1302. Stamping or endorsing dissenting shares

    Within 30 days after the date on which notice of the approval by the
outstanding shares or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder, the shareholder shall submit to the corporation at
its principal office or at the office of any transfer agent thereof, (a) if the
shares are certificated securities, the shareholder's certificates representing
any shares which the shareholder demands that the corporation purchase, to be
stamped or endorsed with a statement that the shares are dissenting shares or to
be exchanged for certificates of appropriate denomination so stamped or endorsed
or (b) if the shares are uncertificated securities, written notice of the number
of shares which the shareholder demands that the corporation purchase. Upon
subsequent transfers of the dissenting shares on the books of the corporation,
the new certificates, initial transaction statement, and other written
statements issued therefor shall bear a like statement, together with the name
of the original dissenting holder of the shares.

Section  1303. Dissenting shareholder entitled to agreed price with interest
thereon; When price to be paid

    (a) If the corporation and the shareholder agree that the shares are
dissenting shares and agree upon the price of the shares, the dissenting
shareholder is entitled to the agreed price with interest thereon at the legal
rate on judgments from the date of the agreement. Any agreements fixing the fair
market value of any dissenting shares as between the corporation and the holders
thereof shall be filed with the secretary of the corporation.

    (b) Subject to the provisions of Section 1306, payment of the fair market
value of dissenting shares shall be made within 30 days after the amount thereof
has been agreed or within 30 days after any statutory or contractual conditions
to the reorganization are satisfied, whichever is later, and in the case of
certificated securities, subject to surrender of the certificates therefor,
unless provided otherwise by agreement.

Section  1304. Action by dissenters to determine whether shares are dissenting
shares or fair market value of dissenting shares or both; Joinder of
shareholders; Consolidation of actions; Determination of issues; Appointment of
appraisers

                                      D-2
<PAGE>
    (a) If the corporation denies that the shares are dissenting shares, or the
corporation and the shareholder fail to agree upon the fair market value of the
shares, then the shareholder demanding purchase of such shares as dissenting
shares or any interested corporation, within six months after the date on which
notice of the approval by the outstanding shares (Section 152) or notice
pursuant to subdivision (i) of Section 1110 was mailed to the shareholder, but
not thereafter, may file a complaint in the superior court of the proper county
praying the court to determine whether the shares are dissenting shares or the
fair market value of the dissenting shares or both or may intervene in any
action pending on such a complaint.

    (b) Two or more dissenting shareholders may join as plaintiffs or be joined
as defendants in any such action and two or more such actions may be
consolidated.

    (c) On the trial of the action, the court shall determine the issues. If the
status of the shares as dissenting shares is in issue, the court shall first
determine that issue. If the fair market value of the dissenting shares is in
issue, the court shall determine, or shall appoint one or more impartial
appraisers to determine, the fair market value of the shares.

Section  1305. Duty and report of appraisers; Court's confirmation of report;
Determination of fair market value by court; Judgment, and payment; Appeal;
Costs of action

    (a) If the court appoints an appraiser or appraisers, they shall proceed
forthwith to determine the fair market value per share. Within the time fixed by
the court, the appraisers, or a majority of them, shall make and file a report
in the office of the clerk of the court. Thereupon, on the motion of any party,
the report shall be submitted to the court and considered on such evidence as
the court considers relevant. If the court finds the report reasonable, the
court may confirm it.

    (b) If a majority of the appraisers appointed fail to make and file a report
within 10 days from the date of their appointment or within such further time as
may be allowed by the court or the report is not confirmed by the court, the
court shall determine the fair market value of the dissenting shares.

    (c) Subject to the provisions of Section 1306, judgment shall be rendered
against the corporation for payment of an amount equal to the fair market value
of each dissenting share multiplied by the number of dissenting shares which any
dissenting shareholder who is a party, or who has intervened, is entitled to
require the corporation to purchase, with interest thereon at the legal rate
from the date on which judgment was entered.

    (d) Any such judgment shall be payable forthwith with respect to
uncertificated securities and, with respect to certificated securities, only
upon the endorsement and delivery to the corporation of the certificates for the
shares described in the judgment. Any party may appeal from the judgment.

    (e) The costs of the action, including reasonable compensation to the
appraisers to be fixed by the court, shall be assessed or apportioned as the
court considers equitable, but, if the appraisal exceeds the price offered by
the corporation, the corporation shall pay the costs (including in the
discretion of the court attorneys' fees, fees of expert witnesses and interest
at the legal rate on judgments from the date of compliance with Sections 1300,
1301 and 1302 if the value awarded by the court for the shares is more than
125 percent of the price offered by the corporation under subdivision (a) of
Section 1301).

Section  1306. Prevention of payment to holders of dissenting shares of fair
market value; Effect

    To the extent that the provisions of Chapter 5 prevent the payment to any
holders of dissenting shares of their fair market value, they shall become
creditors of the corporation for the amount thereof together with interest at
the legal rate on judgments until the date of payment, but subordinate to all
other creditors in any liquidation proceeding, such debt to be payable when
permissible under the provisions of Chapter 5.

Section  1307. Disposition of dividends upon dissenting shares

                                      D-3
<PAGE>
    Cash dividends declared and paid by the corporation upon the dissenting
shares after the date of approval of the reorganization by the outstanding
shares (Section 152) and prior to payment for the shares by the corporation
shall be credited against the total amount to be paid by the corporation
therefor.

Section  1308. Rights and privileges of dissenting shares; Withdrawal of demand
for payment

    Except as expressly limited in this chapter, holders of dissenting shares
continue to have all the rights and privileges incident to their shares, until
the fair market value of their shares is agreed upon or determined. A dissenting
shareholder may not withdraw a demand for payment unless the corporation
consents thereto.

Section  1309. When dissenting shares lose their status

    Dissenting shares lose their status as dissenting shares and the holders
thereof cease to be dissenting shareholders and cease to be entitled to require
the corporation to purchase their shares upon the happening of any of the
following:

    (a) The corporation abandons the reorganization. Upon abandonment of the
reorganization, the corporation shall pay on demand to any dissenting
shareholder who has initiated proceedings in good faith under this chapter all
necessary expenses incurred in such proceedings and reasonable attorneys' fees.

    (b) The shares are transferred prior to their submission for endorsement in
accordance with Section 1302 or are surrendered for conversion into shares of
another class in accordance with the articles.

    (c) The dissenting shareholder and the corporation do not agree upon the
status of the shares as dissenting shares or upon the purchase price of the
shares, and neither files a complaint or intervenes in a pending action as
provided in Section 1304, within six months after the date on which notice of
the approval by the outstanding shares or notice pursuant to subdivision (i) of
Section 1110 was mailed to the shareholder.

    (d) The dissenting shareholder, with the consent of the corporation,
withdraws the shareholder's demand for purchase of the dissenting shares.

Section  1310. Suspension of proceedings for compensation or valuation pending
litigation

    If litigation is instituted to test the sufficiency or regularity of the
votes of the shareholders in authorizing a reorganization, any proceedings under
Sections 1304 and 1305 shall be suspended until final determination of such
litigation.

Section  1311. Shares to which chapter inapplicable

    This chapter, except Section 1312, does not apply to classes of shares whose
terms and provisions specifically set forth the amount to be paid in respect to
such shares in the event of a reorganization or merger.

Section  1312. Attack on validity of reorganization or short-form merger; Rights
of shareholders; Burden of proof

    (a) No shareholder of a corporation who has a right under this chapter to
demand payment of cash for the shares held by the shareholder shall have any
right at law or in equity to attack the validity of the reorganization or
short-form merger, or to have the reorganization or short-form merger set aside
or rescinded, except in an action to test whether the number of shares required
to authorize or approve the reorganization have been legally voted in favor
thereof; but any holder of shares of a class whose terms and provisions
specifically set forth the amount to be paid in respect to them in the event of
a reorganization or short-form merger is entitled to payment in accordance with
those terms and provisions or, if the principal terms of the reorganization are
approved pursuant to subdivision (b) of Section 1202, is entitled to payment in
accordance with the terms and provisions of the approved reorganization.

                                      D-4
<PAGE>
    (b) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, subdivision (a) shall not
apply to any shareholder of such party who has not demanded payment of cash for
such shareholder's shares pursuant to this chapter; but if the shareholder
institutes any action to attack the validity of the reorganization or short-form
merger or to have the reorganization or short-form merger set aside or
rescinded, the shareholder shall not thereafter have any right to demand payment
of cash for the shareholder's shares pursuant to this chapter. The court in any
action attacking the validity of the reorganization or short-form merger or to
have the reorganization or short-form merger set aside or rescinded shall not
restrain or enjoin the consummation of the transaction except upon 10 days'
prior notice to the corporation and upon a determination by the court that
clearly no other remedy will adequately protect the complaining shareholder or
the class of shareholders of which such shareholder is a member.

    (c) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, in any action to attack the
validity of the reorganization or short-form merger or to have the
reorganization or short-form merger set aside or rescinded, (1) a party to a
reorganization or short-form merger which controls another party to the
reorganization or short-form merger shall have the burden of proving that the
transaction is just and reasonable as to the shareholders of the controlled
party, and (2) a person who controls two or more parties to a reorganization
shall have the burden of proving that the transaction is just and reasonable as
to the shareholders of any party so controlled.
