NOVEMBER 23, 1998

Dear Shareholders:

On behalf of the Board of Directors, I cordially invite you to attend a
Special Meeting of the Shareholders (the "Special Meeting") of Information
Storage Devices, Inc. ("ISD" or the "Company") to be held at the Company's
offices at 2045 Hamilton Avenue, San Jose, California, on December 22, 1998 at
9:00 a.m., local time.

At the Special Meeting, holders of Common Stock (the "Common Stock") of ISD
will be asked to consider, approve and adopt an Agreement and Plan of Merger,
dated as of September 11, 1998 (the "Merger Agreement"), among ISD, Winbond
Electronics Corporation, a corporation organized under the laws of the Republic
of China in Taiwan ("Winbond"), Winbond Int'l Corporation, a British Virgin
Islands corporation ("WIC"), Oriole Holding Corporation, a Delaware corporation
("Oriole") and Winbond Acquisition Corporation, a California corporation and a
wholly-owned subsidiary of Oriole ("Merger Sub"), providing for, among other
things, the merger of Merger Sub with and into ISD (the "Merger").

Upon consummation of the Merger (i) each holder of issued and outstanding
shares of ISD Common Stock will receive $7.50 per share, in cash, without
interest (the "Cash Consideration"); (ii) ISD will become a wholly-owned
subsidiary of Oriole; and (iii) each share not owned by Winbond, WIC, Oriole,
Merger Sub or any other affiliate of Winbond will be automatically canceled and
converted into the right to receive the Cash Consideration. The Merger Agreement
also provides that all of the options to purchase ISD Common Stock that are
outstanding immediately prior to the effective time of the Merger will be
canceled at the effective time and the holders will be entitled to receive from
ISD, immediately prior to the effective time of the Merger, for each share
subject to such option, an amount of cash equal to the excess, if any, of the
Cash Consideration over the exercise price per share of such option, subject to
any required withholding taxes. A copy of the Merger Agreement is attached to
the accompanying Proxy Statement as Appendix A.

AFTER CAREFUL CONSIDERATION, THE ISD BOARD OF DIRECTORS HAS DETERMINED THAT
THE MERGER IS IN THE BEST INTERESTS OF ISD AND ITS SHAREHOLDERS. In addition,
the ISD Board of Directors received a written opinion dated September 10, 1998
from its financial advisor, BancBoston Robertson Stephens Inc. ("Robertson
Stephens"), to the effect that, as of such date and subject to certain matters
and exceptions set forth in Robertson Stephens' opinion, the Cash Consideration
to be received by Holders of ISD Common Stock (as defined in the Robertson
Stephens opinion) in the Merger was fair to such holders from a financial point
of view. The full text of Robertson Stephens' opinion is attached to the
accompanying Proxy Statement as Appendix B. Shareholders are urged to, and
should, read such opinion in its entirety.

Enclosed is a Notice of Special Meeting of Shareholders and a Proxy
Statement which describe, and contain other information relating to, the Merger.
You are urged to read all of these materials carefully. The affirmative vote of
the holders of a majority of the shares of ISD Common Stock outstanding is
required to approve the Merger Agreement and the Merger. Your participation in
the Special Meeting, in person or by proxy, is therefore especially important.
WHETHER OR NOT YOU PLAN TO ATTEND THE SPECIAL MEETING IN PERSON, PLEASE
COMPLETE, SIGN, DATE AND PROMPTLY RETURN THE ENCLOSED PROXY CARD IN THE ENVELOPE
PROVIDED. YOUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THE MERGER.

I strongly support the Merger and join with the other members of the ISD
Board of Directors in recommending it. We urge you to vote in favor of adoption
and approval of the Merger Agreement and the Merger.

For the Board of Directors

SUMMARY

The following is a brief summary of certain information contained elsewhere
in this Proxy Statement. The summary does not contain a complete description of
the terms of the Merger and is qualified in its entirety by reference to the
full text of this Proxy Statement and the Appendices hereto. ISD shareholders
are urged to read this Proxy Statement and the Appendices hereto in their
entirety.

This Proxy Statement is furnished in connection with the solicitation by
the ISD Board of proxies from holders of ISD Common Stock for use at the Special
Meeting. At the Special Meeting, the ISD shareholders will be asked to approve
and adopt the Merger Agreement and approve the Merger. As a result of the
Merger, ISD will become a wholly owned subsidiary of Oriole. After the
consummation of the Merger, the former shareholders of ISD will have no
continuing equity interest in ISD or Winbond, and, therefore, will not share in
future earnings, dividends or growth, if any, of the combined company. A copy of
the Merger Agreement is attached as Appendix A to this Proxy Statement.

THE SPECIAL MEETING

DATE, TIME AND PLACE

The Special Meeting will be held at the Company's offices at 2045 Hamilton
Avenue, San Jose, CA 95125, on December 22, 1998, at 9:00 a.m., local time. At
the Special Meeting, shareholders of ISD will be asked to approve and adopt the
Merger Agreement and the Merger. See "The Special Meeting -- Date, Time, Place
and Purpose."

RECORD DATE AND OUTSTANDING SHARES

Only holders of record of ISD Common Stock at the close of business on
November 13, 1998 (the "Record Date") are entitled to notice of and to vote at
the Special Meeting. At the close of business on the Record Date, there were
9,958,194 shares of ISD Common Stock outstanding, each of which is entitled to
one vote. See "The Special Meeting -- Record Date and Outstanding Shares."

On the Record Date, directors and executive officers of ISD and their
affiliated entities as a group beneficially owned 1,562,845 shares of ISD Common
Stock or approximately 15.7% of the outstanding shares of ISD Common Stock. On
the Record Date, Winbond and certain wholly-owned subsidiaries of Winbond
beneficially owned 1,400,000 shares of ISD Common Stock, or approximately 14.1%
of the outstanding shares of ISD Common Stock. Certain of such holders holding
in the aggregate 2,361,852 shares of ISD Common Stock, or approximately 23.7% of
the shares of ISD Common Stock outstanding on the Record Date, have agreed to
vote such shares for approval and adoption of the Merger Agreement and approval
of the Merger. See "Terms of the Merger -- Officer and Director Voting
Agreements."

VOTE REQUIRED; QUORUM

A majority of the shares outstanding on the Record Date will constitute a
quorum for the transaction of business. Abstentions will be considered present
at the Special Meeting for the purpose of determining a quorum. If a broker
indicates on a proxy that such broker does not have discretionary authority to
vote as to certain shares of ISD Common Stock held of record by such broker,
such shares will be counted for purposes of determining the presence or absence
of a quorum for the transaction of business. See "The Special Meeting -- Vote
Required; Quorum."

RECOMMENDATION OF THE ISD BOARD

The ISD Board, by unanimous vote, has adopted and approved the Merger
Agreement and the transactions contemplated thereby, and has determined that the
Merger is in the best interests of ISD and its shareholders. After careful
consideration, the ISD Board unanimously recommends a vote FOR approval of the
Merger Agreement and the Merger.

LITIGATION RELATED TO THE MERGER AND THE EFFECT OF A MAJORITY AFFIRMATIVE VOTE

On September 17, 1998, a complaint was filed against ISD, its directors and
Winbond in the Santa Clara County Superior Court, Case No. CV776731 (the
"Abraham Action"), bearing the caption "Jeffery S. Abraham, individually and on
behalf of all persons similarly situated, Plaintiff v. David L. Angel, Frederick
B. Bamber, Eugene J. Flath, Alan V. King, Eric J. Ochiltree, Frederick L.
Zieber, Information Storage Devices, Incorporated, Winbond Electronics
Corporation, Winbond International Corporation, Peaceful River Corporation,
Pigeon Creek Holding Company, Ltd., Winbond Acquisition Corporation, and Does 1
Through 100 inclusive, Defendants." Defendants David L. Angel, Frederick B.
Bamber, Eugene J. Flath, Alan V. King, Eric J. Ochiltree, Frederick L. Zieber
and Information Storage Devices, Incorporated are referred to as the "ISD
Defendants" and Defendants Winbond Electronics Corporation, Winbond
International Corporation, Peaceful River Corporation, Pigeon Creek Holding
Company, Ltd. and Winbond Acquisition Corporation are referred to as the
"Winbond Defendants." A copy of the complaint is attached to this Proxy
Statement as Appendix D. Mr. Abraham seeks to have the matter certified as a
class action of the holders of ISD Common Stock. Mr. Abraham alleges that the
intention of the ISD Defendants to pursue the Merger is in breach of their
fiduciary duties owed to holders of ISD Common Stock to take all necessary steps
to ensure that such holders will receive the maximum value realizable for their
shares in any extraordinary transaction involving ISD. Mr. Abraham alleges that
the Winbond Defendants knowingly aided and abetted the breaches of fiduciary
duty committed by the ISD Defendants. Mr. Abraham further alleges that the Cash
Consideration to be paid in connection with the Merger allegedly does not
reflect the fair value of ISD's equity, does not offer a control premium, is
less than the consideration proposed to be paid in a previous offer, and is less
than the intrinsic value of ISD's equity. He also alleges that the Merger is not
the result of arm's length negotiation and that it was fixed arbitrarily by ISD
and agreed to by the Defendants as part of the unlawful plan and scheme to
obtain the entire ownership of ISD at the lowest possible price. See Appendix D
for a full and complete statement of Mr. Abraham's allegations. The complaint
seeks a preliminary and permanent injunction against the Merger, rescission of
the Merger if it is consummated, an accounting for all profits realized or to be
realized by the Defendants as a result of the Merger, appointment of a committee
of ISD shareholders and their representatives to assist in the independent
evaluation of any transaction for ISD's shares, and unspecified compensatory
damages and attorneys' fees. ISD is not aware of any pending motion for a
preliminary injunction or other interim relief in connection with the Abraham
Action. There has been no formal discovery to date, although plaintiff has
served a request for production of documents on ISD. After review of the
complaint and based upon its understanding of the facts, ISD believes that the
allegations of the complaint are without merit and intends to defend the Abraham
Action vigorously.

In the event a majority of the shares of ISD Common Stock outstanding vote
in the affirmative to approve the Merger Agreement and the Merger, the
Defendants in the Abraham Action intend to rely upon the approval of the Merger
Agreement and the Merger in defense of the claims asserted by Mr. Abraham.
Specifically, Defendants in the Abraham Action intend to argue that approval of
the Merger Agreement and the Merger by the holders of a majority of the shares
of ISD Common Stock constitutes a ratification of the conduct that is the
subject of Mr. Abraham's complaint. Defendants further intend to argue that such
ratification constitutes a complete defense to Mr. Abraham's claims or otherwise
operates to protect Defendants from liability or increase Mr. Abraham's burdens
of pleading and proof in the Abraham Action.

subsidiary of Winbond. See "Information Concerning Winbond Electronics
Corporation."

REASONS FOR THE MERGER

ISD's Reasons for the Merger. In reaching its conclusion to approve the
Merger Agreement and the Merger, the ISD Board considered a number of factors,
including: (i) ISD's business, financial condition, results of operations,
assets, liabilities, business strategy and prospects for future growth, as well
as various uncertainties associated with those prospects; (ii) the view of ISD's
management that ISD would likely face increasing difficulties as a stand-alone
company; (iii) the current state and volatility of the markets for and customers
of ISD's products; (iv) the withdrawal of the one competing bid to acquire ISD
and the absence of other strategic alternatives that were likely to enhance
long-term shareholder value; (v) the fact that the $7.50 per share to be
received by the shareholders of ISD would be payable in cash, thus eliminating
any uncertainties in valuing the consideration to be received by the ISD
shareholders; (vi) the fact that the Merger would not be subject to any
financing condition; and (vii) the opinion of BancBoston Robertson Stephens Inc.
("Robertson Stephens"), dated September 10, 1998, to the effect that as of such
date the Cash Consideration to be received by Holders of ISD Common Stock in the
Merger was fair to such holders from a financial point of view. The full text of
Robertson Stephens' opinion, which sets forth the assumptions made, matters
considered and limitations on the review undertaken in connection with the
opinion, is attached to this Proxy Statement as Appendix B. Shareholders are
urged to, and should, read such opinion in its entirety. See "Approval of the
Merger -- ISD's Reasons for the Merger."

Winbond's Reasons for the Merger. Winbond considers the Merger to be
beneficial to Winbond and its shareholders and will contribute to the success of
the combined company for the following reasons: (i) the addition of ISD's
ChipCorder product lines to Winbond's product portfolio will position Winbond to
have one of the strongest voice recording and playback IC product lines in the
world; (ii) the Merger will provide an

5
<PAGE> 11

opportunity to increase sales of ISD's products through Winbond's marketing
channels; (iii) the Merger will allow Winbond to increase its presence in the
United States; (iv) the combined experience and financial resources of the
combined company will promote the continued development of ISD's voice record
and playback IC products; and (v) the Merger will accelerate the commencement of
the manufacture of ISD's products in Winbond's wafer fabrication facilities. See
"Approval of the Merger -- Winbond's Reasons for the Merger."

OPINION OF ISD'S FINANCIAL ADVISOR

On September 10, 1998, Robertson Stephens delivered its written opinion
(the "Robertson Stephens Opinion") to the ISD Board that, as of the date of such
opinion, the Cash Consideration was fair, from a financial point of view, to the
holders of ISD Common Stock, excluding Winbond, Merger Sub, any affiliates of
Winbond and holders of Dissenting Shares (collectively, the "Holders of ISD
Common Stock").

The full text of the Robertson Stephens Opinion, which sets forth the
assumptions made, matters considered and limitations on the review undertaken in
connection with the Robertson Stephens Opinion, is attached hereto as Appendix B
and is incorporated herein by reference. The Robertson Stephens Opinion referred
to herein does not constitute a recommendation as to how any holder of ISD
Common Stock should vote upon or take any other action with respect to the
Merger. Shareholders of ISD are urged to, and should, read the Robertson
Stephens Opinion in its entirety. See "Approval of the Merger -- Opinion of
ISD's Financial Advisor."

CERTAIN US FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

If the Merger is consummated, the exchange of shares of ISD Common Stock in
the Merger for the Cash Consideration will be a taxable transaction for United
States federal income tax purposes and may also be a taxable transaction under
applicable state, local or foreign tax laws. Because of the complexities of the
tax laws, holders of shares of ISD Common Stock are advised to consult their own
tax advisors concerning the applicable US federal, state, local, foreign and
other tax consequences resulting from the Merger. See "Approval of the
Merger -- Material US Federal Income Tax Consequences of the Merger."

ACCOUNTING TREATMENT

Winbond will account for the Merger under the purchase method of accounting
whereby the purchase price will be allocated based on the fair value of the
assets acquired and the liabilities assumed by Winbond. See "Approval of the
Merger -- Accounting Treatment."

GOVERNMENT AND REGULATORY APPROVALS

Under the Hart-Scott-Rodino Antitrust Improvements Act (the "HSR Act") and
the rules promulgated under the HSR Act by the U.S. Federal Trade Commission
("FTC"), the Merger cannot be effected until notifications have been given to
the FTC, and the specified waiting period has expired or terminated early. All
required filings under the HSR Act have been made and the waiting period has
been terminated. See "Approval of the Merger -- Government and Regulatory
Approvals."

DISSENTERS' RIGHTS

If the Merger Agreement is approved by the required vote of the ISD
shareholders and is not abandoned or terminated, each holder of ISD Common Stock
who voted against the Merger may, by complying with Sections 1300 through 1312
of the CGCL, be entitled to dissenters' rights as described therein, provided
that (i) such holder's shares of ISD Common Stock are subject to restriction on
transfer imposed by ISD or by any law or regulation or (ii) demands for payment
pursuant to such dissenters' rights are filed with respect to 5% or more of the
outstanding shares of ISD Common Stock on or before the date of the Special
Meeting. The obligations of Winbond to effect the Merger are subject to the
condition that less than 5% of the outstanding shares of ISD Common Stock are
voted against the Merger. While this condition is waivable, Winbond has no
current intention to waive such condition. See "Approval of the
Merger -- Dissenters' Rights."

<PAGE> 12

INTERESTS OF CERTAIN PERSONS IN THE MERGER

Certain members of ISD's management (as well as other ISD employees) have
interests in the Merger that are different from, or in addition to, the
interests in the Merger of ISD shareholders generally. In January 1996, the
Company entered into Employment Agreements with David L. Angel, Chairman of the
Board and Chief Executive Officer and Felix J. Rosengarten, Vice President,
Finance and Administration and Chief Financial Officer. In November 1996, the
Company entered into an Employment Agreement with Eric J. Ochiltree, President
and Chief Operating Officer, and amended Mr. Angel's and Mr. Rosengarten's
Employment Agreements (as amended, the "Employment Agreements"). Under the terms
of the Employment Agreements, in the event of a corporate transaction, such
executive officer shall be entitled to the following compensation and benefits:
(i) a lump sum payment equal to 2 1/2 years of pay at the employee's gross base
annual salary rate and (ii) the acceleration of all of the employee's unvested
outstanding stock options under the Company's 1987 Stock Option Plan and/or 1994
Equity Incentive Plan. The consummation of the transactions contemplated by the
Merger Agreement constitutes a corporate transaction for purposes of the
Employment Agreements. The current annual salary of each of the above executive
officers is as follows: $249,000 for Mr. Angel; $225,000 for Mr. Ochiltree; and
$163,000 for Mr. Rosengarten. The amount payable to each director and executive
officer in exchange for options is enumerated in "Approval of the
Merger -- Interests of Certain Persons in the Merger." In addition to the
foregoing, certain ISD management personnel (including the above referenced
individuals) may enter into employment agreements or arrangements with Winbond
that will become effective on or after consummation of the Merger. Also, certain
of the three ISD executive officers identified above may seek to have ISD modify
his Employment Agreement (subject to the approval of Winbond as required under
the Merger Agreement) to minimize his tax obligations as a result of the Merger.
In addition, Winbond expects to propose key employee retention incentive plans
and modified compensation packages payable over two years. The additional
compensation offered through these arrangements will be payable based on
continued service and, in some cases, on the achievement of performance
objectives, and could materially increase the benefits of the Merger to the
participating employees, including senior management personnel of ISD. Winbond
anticipates that the aggregate amount of such additional compensation payable to
all participating employees would be at least $4.0 million. As a result of the
foregoing, certain officers and employees of ISD may have personal interests in
the Merger which are not identical to the interests of other ISD shareholders.
See "Approval of the Merger -- Interests of Certain Persons in the Merger."

SOURCE AND AMOUNT OF FUNDS

The total amount of funds required by Oriole to pay the Cash Consideration
is estimated to be approximately $64 million. Oriole will obtain such amounts
from Winbond, which will provide such amounts from its working capital and other
customary financing sources. As of June 30, 1998, Winbond had cash and cash
equivalents calculated in accordance with Republic of China ("R.O.C.") GAAP in
excess of NT $13,527,487,959 (or US $392,215,000, on the basis of NT $34.49 = US
$1.00). The shares of ISD Common Stock owned by the subsidiaries of Winbond will
be transferred to Oriole and will be canceled in the Merger and no consideration
will be paid pursuant to the Merger Agreement for such shares. See "Information
Concerning Winbond Electronics Corporation."

TERMS OF THE MERGER

Effective Time; Closing Date

The Merger will become effective upon the filing of the required documents
with the Secretary of State of the State of California in accordance with the
CGCL (the "Effective Time of the Merger"). The closing of the Merger (the
"Closing") will take place as soon as practicable on the later of (i) the date
of the Special Meeting or (ii) the first business day after satisfaction of the
latest to occur of the conditions to the Merger, unless Winbond and ISD agree in
writing on another date. The parties anticipate that the Closing will occur on
or about December 22, 1998. See "Terms of the Merger -- Effective Time; Closing
Date."

7
<PAGE> 13

Manner and Basis of Transferring Shares; Treatment of Options

At the Effective Time of the Merger, ISD will continue as the surviving
corporation (the "Surviving Company") and will become a wholly-owned subsidiary
of Oriole. By virtue of the Merger and without any action on the part of the
holder of any shares of ISD Common Stock, each issued and then outstanding share
of ISD Common Stock (other than shares owned by WIC, Oriole, Merger Sub, any
member of the Winbond Group or any other subsidiary of Winbond and any shares of
ISD Common Stock that are held by shareholders who have demanded properly in
writing dissenters' rights with respect to such shares in accordance with the
CGCL) shall be automatically converted into the right to receive $7.50, in cash,
without interest (the "Cash Consideration"). See "Terms of the Merger -- Manner
and Basis of Transferring Shares; Treatment of Options."

Pursuant to the Merger Agreement, ISD has agreed to use its best efforts to
deliver to Winbond, before the Closing, consents in writing from the holders of
all options outstanding on such date that had been granted before the date of
the Merger Agreement pursuant to the ISD 1994 Directors Stock Option Plan, 1994
Equity Incentive Plan and 1987 Stock Option Plan (the "ISD Option Plans"),
pursuant to which such holders consent to the purchase of their options by ISD
immediately prior to the Effective Time of the Merger. The purchase price of
each such option will be an amount (less any applicable withholding taxes) equal
to the excess, if any, of the Cash Consideration over the per share exercise
price of such option, multiplied by the number of shares of ISD Common Stock
underlying such option immediately before the Effective Time of the Merger.
Pursuant to the Merger Agreement, the ISD 1994 Employee Stock Purchase Plan will
terminate at the Effective Time of the Merger. See "Terms of the
Merger -- Manner and Basis of Transferring Shares; Treatment of Options."

Surrender and Exchange of Certificates

As soon as practicable after the Effective Time of the Merger, and after
surrender to an agent appointed by Oriole (the "Exchange Agent") of any
certificate that represented shares of ISD Common Stock before the Effective
Time of the Merger ("Certificate"), the person in whose name such Certificate is
registered will receive a check for the Cash Consideration in respect of the
shares represented by the Certificate. In the event of a transfer of ownership
of any shares of ISD Common Stock that is not registered in ISD's transfer
records, payment may be made to a person other than the person in whose name the
surrendered Certificate is registered if such Certificate is properly endorsed
for transfer and the person requesting payment discharges any transfer or other
tax required by reason of payment of the Cash Consideration to a person other
than the registered holder. No interest will be paid or will accrue on the cash
payable upon the surrender of any Certificates. ISD SHAREHOLDERS MUST NOT
SURRENDER CERTIFICATES UNTIL THEY RECEIVE THE LETTER OF TRANSMITTAL FROM THE
EXCHANGE AGENT. See "Terms of the Merger -- Surrender and Exchange of
Certificates."

Conduct of ISD's Business Before the Merger

Pursuant to the Merger Agreement, ISD has agreed to use its best efforts to
preserve intact its business organization and to maintain satisfactory
relationships with its licensors, suppliers, distributors, employees and
customers. ISD has also agreed that it will notify and consult with Winbond
before taking any material action or entering into any material agreement with
respect to its business or assets. In addition, except as permitted by the
Merger Agreement, ISD has agreed that it will not, without the prior written
consent of Winbond, take certain other actions, including actions with respect
to its Articles of Incorporation, Bylaws, capital stock, options to purchase
capital stock, properties, assets, employment or consulting agreements,
compensation

8
<PAGE> 14

arrangements, indebtedness or capital expenditures. ISD has agreed that it will
terminate the Rights Agreement between ISD and The First National Bank of Boston
as Rights Agent, without any rights thereunder becoming exercisable with respect
to the Merger.

Winbond has advised ISD's senior management that, after the Merger, Oriole
intends to leave the ISD work force in place, as a general matter, for one
calendar quarter, after which ISD's management and the management of Winbond
Electronics Corporation America will decide how to combine the companies'
operations. In any event, Winbond has agreed that, for a period of six months
after the Closing, it will provide ISD's employees with coverage under employee
benefit plans no less beneficial than those in effect as of the date of the
Merger Agreement, except that all of the ISD Option Plans and the ISD employee
stock purchase plan will be terminated on the Closing and the bonus and
incentive plans after the Merger may differ from those in effect before the
Effective Time of the Merger.

The Merger Agreement contains additional covenants and agreements of the
parties. See "Terms of the Merger -- Conduct of ISD's Business Before the
Merger."

Exclusivity

Under the Merger Agreement, the respective obligations of each party to

shareholders; (ii) execution and delivery by the parties of the Merger Agreement
and all ancillary documents and agreements provided in the Merger Agreement;

Termination of the Merger Agreement

The Merger Agreement may be terminated at any time before the Closing,
whether before or after approval by the ISD shareholders (a) by mutual agreement
of the ISD Board and the Winbond board of directors; (b) by the ISD Board or the
Winbond board of directors if the Closing has not occurred by December 31, 1998
or such other date as mutually agreed by the parties; (c) by the Winbond board
of directors if (i) any of the conditions to Winbond's obligations specified in
the Merger Agreement are not satisfied or waived by Winbond or (ii) ISD's
shareholders do not approve the Merger Agreement and the Merger; (d) by the ISD
Board if any of the conditions to ISD's obligations specified in the Merger
Agreement have not been satisfied or waived by ISD; (e) by Winbond if (i) the
ISD Board withdraws or modifies its recommendation in favor of the Merger
Agreement and the Merger or (ii) before the Special Meeting, a tender offer
other than by Winbond or its affiliates is commenced and the ISD Board does not
recommend against acceptance of such tender offer within the time period
required by the regulations of the Commission; (f) by ISD if the ISD Board
determines in good faith that an Acquisition Proposal becomes a Superior
Proposal; or (g) by the board of directors of either Winbond or ISD if (i) there
is a nonappealable order of a federal or state court in effect preventing
consummation of the Merger or (ii) any action is taken, or any statute, rule,
regulation or order is enacted, promulgated or issued that applies or is deemed
to apply to the Merger by any governmental entity that would make consummation
of the Merger illegal. See "Terms of the Merger -- Termination of the Merger
Agreement."

The complaint in the Abraham Action, a copy of which is attached to this
Proxy Statement as Appendix D, seeks a preliminary and permanent injunction
against the Merger, rescission of the Merger if it is consummated, an accounting
for all profits realized or to be realized by the defendants as a result of the
Merger, appointment of a committee of ISD shareholders and their representatives
to assist in the independent evaluation of any transaction for ISD's shares, and
unspecified compensatory damages and attorney's fees. It is a condition to the
obligations of both ISD and Winbond under the Merger Agreement that there be no
litigation or similar action pending seeking to enjoin or otherwise stop or
delay the transactions contemplated by the Merger Agreement. ISD and Winbond
each will have the right to terminate the Merger Agreement on the date that the
parties mutually agree upon for the closing under the Merger Agreement if, at
that date, the complaint seeks to enjoin or otherwise stop or delay the
transactions contemplated by the Merger Agreement. Neither party currently
intends to exercise such right. See "Information Concerning ISD's
Business -- Legal Proceedings."

Break-up Fee

The Merger Agreement provides that ISD must pay to Winbond $4.0 million if
(a) the Merger Agreement is terminated other than due to fraud of Winbond and,
within 18 months after September 11, 1998, ISD enters into an agreement for, or
otherwise consummates, any of the transactions described above under the heading
"Exclusivity;" (b) ISD's shareholders do not approve the Merger Agreement and
the Merger; (c) Winbond terminates the Merger Agreement because (i) the ISD
Board has withdrawn or modified its recommendation in favor of the Merger
Agreement and the Merger or (ii) before the Special Meeting, a tender offer
other than by Winbond or its affiliates has commenced and the ISD Board has not
recommended against acceptance of such tender offer within the time period
required by the regulations of the Commission; or (d) ISD terminates the Merger
Agreement because the ISD Board has determined in good faith that an Acquisition
Proposal has become a Superior Proposal.

Peaceful River Corp. or Pigeon Creek Holding Co., Ltd. if the failure to close
is due to a material adverse change in the financial condition, results of
operations or business of ISD after September 11, 1998, as determined in good
faith by the Winbond board of directors. No fee is payable by any party if the
failure to close before December 31, 1998 is due to any of the following: (i)

written notice of the expiration of the HSR Act waiting period or has notified
ISD or Winbond of its or their intention to take action to stop or delay the
Merger; (ii) litigation or other similar action seeking to enjoin or otherwise

Winbond, WIC, Oriole, Merger Sub, Peaceful River Corp., Pigeon Creek Holding
Co., Ltd. or any other subsidiary of Winbond to approve the Merger Agreement and

THE SPECIAL MEETING

DATE, TIME, PLACE AND PURPOSE

The Special Meeting will be held at the Company's offices at 2045 Hamilton
Avenue, San Jose, CA 95125, on December 22, 1998, at 9:00 a.m., local time. At
the Special Meeting, shareholders of ISD will be asked to approve and adopt the
Merger Agreement and the Merger. The Merger Agreement is attached hereto as
Appendix A. See "Terms of the Merger."

RECORD DATE AND OUTSTANDING SHARES

VOTING OF PROXIES

The proxy accompanying this Proxy Statement is solicited on behalf of the
ISD Board for use at the Special Meeting. ISD shareholders are requested to
complete, date and sign the accompanying proxy and promptly return it in the
enclosed envelope or otherwise mail it to ISD. All properly executed proxies
received by ISD prior to the vote at the Special Meeting that are not revoked
will be voted at the Special Meeting in accordance with the instructions
indicated on the proxies or, if no direction is indicated, to approve and adopt
the Merger Agreement and the Merger.

It is not anticipated that any matter not referred to herein will be
presented for action at the Special Meeting. If any other matters are properly
brought before the Special Meeting, the persons named in the proxies will have
discretion to vote on such matters in accordance with their best judgment.

VOTE REQUIRED; QUORUM

The affirmative vote of the holders of a majority of the outstanding shares
of ISD Common Stock is required to approve and adopt the Merger Agreement and to
approve the Merger. For this purpose, (i) the total number of shares cast for
the proposal or giving no instructions will be considered to have been voted in
favor of the proposal and (ii) abstentions and broker non-votes have the same
effect as votes against the Merger. If sufficient votes in favor of the proposal
are not received by the date of the Special Meeting, the persons named as
proxies may propose one or more adjournments of the Special Meeting to permit
further solicitations of proxies. Any such adjournment would require the
affirmative vote of the majority of the shares of ISD Common Stock present in
person or represented by proxy at the Special Meeting and entitled to vote. If a
proposal for such an adjournment of the Special Meeting is properly brought
before the Special Meeting, all properly executed and delivered proxies that are
not revoked will be voted in favor of such adjournment, except for proxies that
instruct the proxy holders to vote against the Merger Agreement and the Merger.

On the Record Date, directors and executive officers of ISD and their
affiliated entities as a group beneficially owned 1,562,845 shares of ISD Common
Stock or approximately 15.7% of the outstanding shares of ISD Common Stock. On
the Record Date, Winbond and certain wholly-owned subsidiaries of Winbond, which
are WIC, Peaceful River Corp. and Pigeon Creek Holding Co., Ltd., beneficially
owned 1,400,000 shares of ISD Common Stock, or approximately 14.1% of the
outstanding shares of ISD Common Stock. Certain of such holders holding in the
aggregate 2,361,852 shares of ISD Common Stock, or approximately 23.7% of the
shares of ISD Common Stock outstanding on the Record Date, have agreed to

13
<PAGE> 19

vote such shares for approval and adoption of the Merger Agreement and approval
of the Merger. See "Terms of the Merger -- Officer and Director Voting
Agreements."

SOLICITATION OF PROXIES AND EXPENSES

ISD will pay the expenses of soliciting proxies for the Special Meeting.
Following the original mailing of the proxies and other soliciting materials,
ISD will request that brokers, custodians, nominees and other record holders
forward copies of the proxy and other soliciting materials to persons for whom
they hold shares of ISD Common Stock and request authority for the exercise of
proxies. In such cases, upon the request of the record holders, ISD will
reimburse such holders for their reasonable expenses. The original solicitation
of proxies by mail may be supplemented by telephone, telegram and personal
solicitation by directors, officers and regular employees of ISD.

REVOCABILITY OF PROXIES

Any person signing a proxy in the form accompanying this Proxy Statement
has the power to revoke it prior to the Special Meeting or at the Special
Meeting prior to the vote pursuant to the proxy. A proxy may be revoked by a
written instrument delivered to ISD stating that the proxy is revoked, by a
subsequent proxy that is signed by the person who signed the earlier proxy and
is presented at the Special Meeting or by attendance at the Special Meeting and
voting in person. Please note, however, that, if a shareholder's shares are held
of record by a broker, bank or other nominee and that shareholder wishes to vote
at the Special Meeting, the shareholder must bring to the Special Meeting a
letter from the broker, bank or other nominee confirming that shareholder's
beneficial ownership of the shares.

DISSENTERS' RIGHTS

Holders of shares of ISD Common Stock who fully comply with the
requirements of Chapter 13 of the CGCL may be entitled, if the Merger is
consummated, to exercise dissenters' rights with respect to their shares.
Failure to take any required step in connection with the exercise of dissenters'
rights may result in the termination or waiver of such rights. See "Approval of
the Merger -- Dissenters' Rights" for a statement of the rights of dissenting
holders and a description of the procedures required to be followed to exercise
such rights, and the text of Chapter 13 of the CGCL attached hereto as Appendix
C.

INDEPENDENT PUBLIC ACCOUNTANTS

Arthur Andersen LLP serves as the Company's independent public accountants.
Representatives of Arthur Andersen LLP will be present at the Special Meeting,
will have the opportunity to make a statement at the Special Meeting if they
desire to do so and will be available to respond to appropriate questions.

RECOMMENDATION OF THE ISD BOARD

<PAGE> 20

APPROVAL OF THE MERGER

This section contains forward-looking statements that involve risks and
uncertainties. Words such as "expects," "anticipates," "intends," "plans,"
"believes," "seeks," "estimates," variations of such words and similar
expressions are intended to identify these forward-looking statements. The
forward-looking statements reflect the best judgment of the management of ISD
and Winbond based on factors currently known and are subject to risks and
uncertainties. Actual results could differ materially from those anticipated in
the forward-looking statements as a result of certain factors, including those
set forth under "ISD Management's Discussion and Analysis of Financial Condition
and Results of Operations -- Other Factors That May Affect Future Operating
Results" and elsewhere in this Proxy Statement.

ISD'S REASONS FOR THE MERGER

In reaching its conclusion to approve the Merger Agreement and the Merger,
the Board considered the following factors:

- ISD's business, financial condition, results of operations, assets,
liabilities, business strategy and prospects for future growth, as well
as various uncertainties associated with those prospects;

- the view of ISD's management that ISD would likely face increasing
difficulties as a stand-alone company while it continues to focus on the
highly competitive, rapidly changing communications market, where ISD's
competitors are large semiconductor companies and where a high level of
investment would likely be necessary, among other purposes, to create
larger systems on a chip, to develop or acquire needed technologies, to
achieve cost structures through economies of scale and to maintain the
necessary sales channels and sales support networks.

- the current state and volatility of the markets for and customers of
ISD's products;

- the withdrawal of the one competing bid to acquire ISD and the absence of
other strategic alternatives that were likely to enhance long-term
shareholder value;

- the fact that the $7.50 per share to be received by the shareholders of
ISD would be payable in cash, thus eliminating any uncertainties in
valuing the consideration to be received by the ISD shareholders; and

- the fact that the Merger would not be subject to any financing condition.

In particular, the ISD Board considered the fact that ISD's current product
lines have a limited lifespan. In order for ISD to maintain its competitive
position over the next two years, the Board determined that the Company must
invest heavily in product development and marketing at least over the next year.
For example, investment would be necessary for the Company to create more
competitive systems on a single chip, to develop or acquire needed technologies,
to achieve cost reductions through economies of scale and to develop the markets
for these products. ISD is also facing significant cost pressures as IC prices
decline and expenses for hiring and litigation increase. At July 4, 1998, ISD
had cash, cash equivalents and short-term investments of $28.5 million. Although
the ISD Board considered this amount sufficient to make the needed investments,
upon depletion of its cash reserves, and conservatively assuming no additional
cash available from revenues, the ISD Board concluded that ISD would be
vulnerable if anticipated product enhancements and new products did not achieve
market acceptance.

In considering the Merger, the ISD Board also assessed ISD's prospects for
future growth after losses in nine out of the 10 previous quarters. The markets
for ISD's products are volatile, with the core consumer and communications
markets softening. As a result, ISD's prospects for future growth are uncertain.
The ISD Board discussed that ISD's performance had improved from a net loss of
$6.3 million on net revenues of $19.7 million in the first six months of 1997 to
a net loss of $1.2 million on net revenues of $24.3 million in the first six
months of 1998. Given the market uncertainties and the need for cash investment,
however, the ISD Board identified the risk that ISD would experience significant
difficulty in improving its performance levels over the longer term. Performance
levels also affect recruiting as bonus structures become less attractive,
thereby increasing ISD's need to provide fixed cash compensation.

The ISD Board also considered the market price of the ISD Common Stock.
Like other semiconductor companies that subcontract wafer fabrication to third
parties, the market capitalization of ISD is not significantly in excess of its
cash value and share prices are quickly and adversely affected by reports of
missed performance. Given these factors, the ISD Board identified the risk that
the share price would continue to decline as the Company's cash value diminished
as a result of the product and technology investments necessary over the near
term for future growth. In addition, the ISD Board noted that the offer of $7.50
per share represented a premium of 45% over $5.19, which was the closing sale
price of the ISD Common Stock on July 24, 1998, the trading day before the
announcement of Winbond's intent to acquire ISD.

In the course of its deliberations, the ISD Board reviewed with ISD's
management and financial advisors a number of other factors favoring the Merger.
The additional factors considered by the ISD Board are the following: (i) the
financial and other terms and conditions of the Merger Agreement, which the ISD
Board determined, after consultation with its legal advisors, was reasonable and
thus supported the ISD Board's conclusion; (ii) the fact that Winbond expressed
willingness to retain the Company's key technical and manufacturing employees
and to establish post-Merger bonus plans to retain such employees; and (iii) the
advice and detailed financial analysis provided by Robertson Stephens, including
the opinion of Robertson Stephens, dated September 10, 1998, to the effect that
as of such date the Cash Consideration to be received by Holders of ISD Common
Stock in the Merger was fair to such holders from a financial point of view. In
its consideration of the financial analysis and opinion of Robertson Stephens,
the ISD Board found it noteworthy and supportive of its conclusion that the Cash
Consideration was within or above each implied equity valuation range presented
by Robertson Stephens. See "-- Opinion of ISD's Financial Advisor." The full
text of Robertson Stephens' opinion, which sets forth the assumptions made,
matters considered and limitations on the review undertaken in connection with
the opinion, is attached to this Proxy Statement as Appendix B. Shareholders are
urged to, and should, read such opinion in its entirety. In considering the
Robertson Stephens Opinion, the ISD Board took into account the fees payable to
Robertson Stephens. See "-- Opinion of ISD's Financial Advisor." In addition,
the ISD Board considered the employment agreements with certain executive
officers of ISD and the arrangements for acceleration of the exercisability of
the stock options granted to the employees of ISD. See "-- Interests of Certain
Persons in the Merger."

The ISD Board also considered the following negative factors concerning the
Merger: (i) the risk that the Merger would not be effected, and the disruption
in the business of ISD if the Merger is abandoned; and (ii) the fact that the
ISD shareholders will receive cash in the Merger, which will not afford them the
opportunity to participate in any growth in the business of the combined company
as a shareholder of Winbond.

In view of the wide variety of factors considered in connection with its
evaluation of the Merger, the ISD Board did not assign relative weights to the
specific factors considered in reaching its decision.

WINBOND'S REASONS FOR THE MERGER

Winbond considers the Merger to be beneficial to Winbond and its
shareholders and will contribute to the success of the combined company for the
following reasons:

- The addition of ISD's ChipCorder product lines to Winbond's product
portfolio will position Winbond to have one of the strongest voice
recording and playback IC product lines in the world.

- The Merger will provide an opportunity to increase sales of ISD's
products through Winbond's marketing channels.

- The Merger will allow Winbond to increase its presence in the United
States.

- The combined experience and financial resources of the combined company
will promote the continued development of ISD's voice record and playback
IC products.

- The Merger will accelerate the commencement of the manufacture of ISD's
products in Winbond's wafer fabrication facilities.

BOARD RECOMMENDATION

The ISD Board has adopted and approved the Merger Agreement and the
transactions contemplated thereby and approved the Merger and has determined
that the Merger is fair, from a financial point of view to, and in the best
interests of, ISD and the ISD shareholders.

AFTER CAREFUL CONSIDERATION, THE ISD BOARD UNANIMOUSLY RECOMMENDS A VOTE
FOR THE ADOPTION AND APPROVAL OF THE MERGER AGREEMENT AND FOR APPROVAL OF THE
MERGER.

BACKGROUND OF THE MERGER

The markets in which ISD competes are characterized by rapid technological
change, declining average selling prices and product obsolescence. The
willingness of prospective customers to design ISD's products into their
products depends to a significant extent upon the ability of ISD to price its
products at a level that is cost effective for such customers. In January 1996,
the ISD Board determined that the Company's operating results were unlikely to
return to previous growth levels until the Company's products could be
manufactured in a more advanced process technology. In March 1996, ISD engaged
Robertson Stephens to assist the Company in seeking a strategic partner. In 1996
and through the first quarter of 1997, ISD evaluated a number of possible
strategic relationships of various forms that were identified by Robertson
Stephens. These potential strategic relationships included foundry arrangements,
licensing arrangements and business combinations with numerous other companies.
None of these potential relationships was completed. For example, one potential
partner advised ISD that it wished to invest in markets such as
telecommunications rather than invest in ISD's need for further development of
the EEPROM process technology using geometries of less than 0.8 microns. Another
potential partner advised ISD that it had determined to enter the market for
dynamic random access memory (DRAM) ICs and, therefore, working with ISD would
not fit their strategy. Another potential partner indicated that an alliance
with ISD would require that it build a new factory, at a time when its board of
directors was embarking on a reduced capital expenditure program. Several
potential partners demanded rights to ISD's technology and markets which, in the
judgment of the ISD Board, would have prevented ISD from achieving and
sustaining market recognition in voice solutions. Other potential partners cited
ISD's lack of the required wafer process technology. In addition, in 1996 and
through the first quarter of 1997, Robertson Stephens contacted other parties
that showed no interest in pursuing discussions with ISD regarding a possible
strategic relationship or business combination. At the same time, ISD was
evaluating the anticipated advanced process technology requirements of the
Company on a standalone basis and the probable research and development spending
that would be required to realize the advanced technology.

Prior to May 1998, ISD and Winbond had a foundry manufacturing and
technical exchange relationship. From 1995 through 1997, ISD qualified Winbond's
flash technology and designed two products on such technology. ISD and Winbond
entered into a Foundry Supply Agreement dated May 28, 1997, pursuant to which
Winbond manufactures silicon wafers for ISD according to specific wafer design
and process technology parameters, and ISD purchases the wafers from Winbond
upon completion of the fabrication process. At that time, Winbond was not an ISD
shareholder. In early 1998, ISD released the products to production and to the
market.

On May 22, 1998, Winbond filed a Schedule 13D with the Commission to report
that WIC, Peaceful River Corp. and Pigeon Creek Holding Co., Ltd., all of which
are wholly-owned subsidiaries of Winbond, had accumulated a total of 1,228,000
shares of ISD Common Stock, representing approximately 12.5% of the outstanding
shares as of such date. These shares were acquired on the open market over a
period beginning on April 21 and ending on May 21, 1998, at per share prices
ranging from $5.50 to $6.1250, as follows: 5,000 shares were acquired at a price
of $5.50 per share, 578,000 shares were acquired at a price of $5.75 per share,
100,000 shares were acquired at a price of $5.8125 per share, 80,000 shares were
acquired at a price of $5.8633 per share, 365,000 shares were acquired at a
price of $5.8750 per share and 100,000 shares were acquired at a price of
$6.1250 per share. Subsequent to such filing, ISD became aware that Winbond was
accumulating additional shares of ISD Common Stock. Representatives of Winbond
called Mr. Angel, ISD's

17
<PAGE> 23

Chairman and Chief Executive Officer, and requested the opportunity to meet with
him. They did not state a reason or suggest an agenda for the meeting.

On June 15, 1998, Mr. Angel met with the chairman of another potential
acquirer ("Other Party") who informally expressed an interest in acquiring the
Company at an unspecified price. The chairman of Other Party asked if Mr. Angel
would support an acquisition of the Company by Other Party. Mr. Angel responded
that he would present any acquisition proposed to the ISD Board and that the
directors would consider and respond to any such proposal consistent with their
fiduciary obligations.

On June 22, 1998, Winbond Chairman Arthur Chiao and Winbond Vice President
Archie Yeh visited ISD's corporate headquarters in San Jose, California. They
met with Mr. Angel for approximately one hour. At the meeting, Mr. Angel and Mr.
Chiao discussed the possibility of a future business alliance between ISD and
Winbond but did not make any agreements or formulate any plans for concluding
such an alliance. Mr. Angel did not give a presentation on ISD and no
confidential information of either party was disclosed or discussed at that
meeting. At that meeting, Winbond requested a position on the ISD Board. Mr.
Angel indicated that such requests are considered by the ISD Board as a whole,
but no commitment was made. There were no further discussions regarding Winbond
representation on the ISD Board. Mr. Angel briefly introduced Mr. Chiao and Mr.
Yeh to Mr. Ochiltree, ISD's President and Chief Operating Officer, and Mr.
Rosengarten, ISD's Vice President of Finance and Administration and Chief
Financial Officer. Within a few days of this meeting, ISD and Winbond agreed to
meet in July 1998 in Guam to discuss ways of expanding the parties' existing
business relationship.

On June 23, 1998, ISD had a telephonic conference with representatives of
Robertson Stephens to discuss Mr. Angel's meeting with the chairman of Other
Party and Winbond's Schedule 13D filing and June 22 meeting with ISD. During the
June 23 telephonic conference, ISD requested that Robertson Stephens contact
other parties that might be interested in a possible business combination with
the Company.

On June 29, 1998, the ISD Board met at a regularly scheduled meeting. The
directors discussed the status of ISD's partnership with Winbond, as well as the
other strategic alternatives available to ISD.

On June 30, 1998, Winbond filed Amendment No. 1 to its Schedule 13D to
report an increase in its ownership of shares of ISD Common Stock to a total of
1,360,000 shares, or approximately 13.8% of the shares outstanding. The
Amendment No. 1 also summarized the meeting held on June 22, 1998.

On July 7, 1998, Mr. Angel, Mr. Ochiltree, Mr. Rosengarten, representatives
of ISD's legal counsel, Fenwick & West LLP, and representatives of Robertson
Stephens met with Other Party and the latter's legal and financial advisors.
Discussions took place concerning Other Party's possible interest in the
acquisition of ISD. No agreement or understanding was reached. The ISD Board was
briefed as to such discussions by telephonic conference call on July 8, 1998.

On July 13, 1998, ISD and Winbond signed a Mutual Nondisclosure Agreement
covering the confidential treatment by each party of proprietary information
provided by the other party with respect to general business discussions
including possible alliances, partnerships and/or collaboration.

From July 11, 1998 through July 14, 1998, Messrs. Angel, Ochiltree and
James Brennan, ISD's Vice President of Technology, met in Guam with Messrs. Yeh,
Len-Yi Leu, Winbond's Deputy of Technology Development, and Gauss Chang,
Winbond's Department Manager, Foundry Sales. ISD is in the process of changing
the base technology for its products from EEPROM to Flash technology and Winbond
is ISD's Flash technology manufacturer. The purpose of the meeting was for each
side to discuss marketing strategies, technical issues concerning the
implementation of Winbond's foundry process and ISD's current wafer and
technology requirements, as well as to explore ideas for additional avenues of
business collaboration. The discussions related to Winbond's technology and the
possibility of Winbond obtaining more of ISD's foundry business. The discussions
referenced the possibility that Winbond might make an acquisition proposal at
some point, but no agreement or understanding was reached at the meeting in
Guam. During these meetings, Mr. Angel advised Mr. Yeh that Other Party had
expressed an intent to make a cash offer to acquire all of the outstanding ISD
Common Stock.

18
<PAGE> 24

On July 20, 1998, ISD received a written offer from Other Party for the
acquisition of all of the outstanding shares of ISD Common Stock at a price of
$7.00 per share in cash. This offer was subject to numerous contingencies and
required that ISD sign an agreement that would prevent ISD from discussing any
other acquisition proposal, whether or not such other proposal appeared to be a
more advantageous offer. Given this requirement of a strong no-shop agreement,
the ISD Board determined to allow this offer to lapse without a response from
ISD. On July 20, 1998, the closing price of ISD Common Stock was $5.25 per
share.

Within five days after the meetings between ISD and Winbond in Guam, Lehman
Brothers Inc. ("Lehman Brothers"), the investment bankers retained by Winbond,
contacted Robertson Stephens to determine whether ISD would have interest in
receiving an acquisition proposal from Winbond. Several conversations occurred
between Lehman Brothers and Robertson Stephens between July 17, 1998 and July
23, 1998. Mr. Angel and Mr. Yeh first discussed Winbond's interest in acquiring
all of the outstanding ISD Common Stock during a series of telephone
conversations on July 21, 1998. On the same day, Mr. Angel briefed the ISD Board
via a telephone conference call.

On July 24, 1998, Mr. Angel and Mr. Yeh met in Taipei, Taiwan to further
discuss Winbond's interest in acquiring ISD. At that meeting, Mr. Yeh presented
a non-binding cash offer letter addressed to the ISD Board to acquire all of the
outstanding shares of ISD for $8.25 per share, contingent upon completion of due
diligence. Winbond filed Amendment No. 2 to its Schedule 13D with the Commission
on the same day, to report the offer, as well as an increase in its ownership of
ISD Common Stock to a total of 1,400,000 shares, or approximately 14.2% of the
shares outstanding. Also on July 24, ISD issued its first public announcement of
the offer. On July 24, 1998, the closing sale price of ISD Common Stock was
$5.19 per share.

On July 26, 1998, the ISD Board met via telephone conference call to
discuss the Winbond offer as well as other strategic alternatives.
Representatives of Robertson Stephens and Fenwick & West LLP also participated
in the meeting. At that meeting, the ISD Board authorized management to continue
the discussions.

On August 4, 1998, Mr. Angel met with Messrs. Chiao and Yeh to discuss
various conditions of Winbond's offer to acquire all of the outstanding shares
of ISD's Common Stock. From August 5, 1998 through August 7, 1998, various of
Winbond's executive, engineering, manufacturing, finance and legal personnel,
along with Lehman Brothers and Winbond's outside legal counsel, Graham & James
LLP, visited ISD's corporate headquarters to conduct technical, financial and
legal due diligence. Such due diligence reviews and meetings among ISD, Winbond
and their respective legal counsel and financial advisors continued from August
10, 1998 to September 8, 1998. They also had numerous meetings and conversations
regarding the terms of the Merger Agreement and related documents, including
without limitation whether certain ISD shareholders would enter into voting
agreements with respect to the proposed Merger, the circumstances under which
Winbond or ISD could terminate the Merger Agreement, the conditions upon which
any break-up fees would be payable and the amount of such fees. Concurrently,
Winbond continued its legal and financial due diligence review of ISD.

On August 11, 1998, ISD received an amended offer from Other Party, this
time in the amount of $8.50 per share in cash, which offer was subject to the
same conditions as Other Party's July 20 offer. The closing sale price of ISD
Common Stock on such date was $6.63 per share. On August 13, 1998, the ISD Board
met via conference call to review the status of the Winbond proposal, Other
Party's proposal, and other alternatives available to ISD. From August 19, 1998
through August 21, 1998, Other Party visited ISD's San Jose headquarters and
conducted a due diligence review of technical, financial, legal and other
matters. The information made available to Other Party was the same as that made
available to Winbond. Shortly after completion of its due diligence review,
Other Party withdrew its offer to acquire the outstanding ISD Common Stock and
advised ISD that Other Party had concluded that the cost reduction it had
expected to achieve through the combination of manufacturing organizations and
the elimination of considerable engineering staff would not, in its opinion, be
achieved as a result of the differences between the technologies of the two
companies.

On August 25, 1998, Winbond, along with its counsel and financial advisor,
met with ISD, its legal counsel and financial advisor, to continue their due
diligence review. On August 26, 1998, Mr. Yeh and D.Y. Yang, President of
Winbond, visited ISD's headquarters to discuss with Messrs. Angel and Ochiltree
all

19
<PAGE> 25

remaining unresolved due diligence issues. That evening, Mr. Yeh informed Mr.
Angel that the remaining unresolved due diligence issues had been resolved to
Winbond's satisfaction, and that from Winbond's perspective Winbond was
prepared, pending final Winbond Board of Directors approval, to proceed with the
drafting, negotiation, execution and delivery of a definitive agreement.

On September 5, 1998, Robertson Stephens advised Mr. Angel that it had been
notified that Winbond no longer believed that ISD's value to Winbond was $8.25
per share, citing that Winbond now had more insight into ISD after completing
its due diligence process. Winbond reached this conclusion as a result of its
due diligence review and its view of the performance of the stock market
generally and semiconductor sector companies in particular, as well as the
worsening economic conditions in Taiwan. Mr. Angel was then advised that Winbond
believed the value of ISD to be closer to $7.00 per share. During a telephone
conversation between Mr. Angel and Mr. Chiao on September 5, 1998, Mr. Angel
advised Mr. Chiao that Mr. Angel was not authorized to accept any price less
than $8.25 and therefore, that this was a matter that must be considered by the
ISD Board. Mr. Chiao indicated that he would discuss the matter with his
executive staff and would respond with a revised offer. On September 6, 1998,
Mr. Angel received Winbond's final offer of $7.50 per share, which Winbond
stated to be the best price it could offer. On September 4, 1998, the most
recent trading day before September 6, 1998, the closing sale price of ISD
Common Stock was $6.50 per share.

After receiving Winbond's September 6, 1998, final offer of $7.50 per
share, the ISD Board determined that it would not be beneficial to attempt to
resume discussions with Other Party. The ISD Board reached this judgment in
light of the conclusions expressed by Other Party when it withdrew its August 11
offer to acquire the outstanding ISD Common Stock and the deterioration in the
market price of Other Party's common stock, which significantly increased the
uncertainty of Other Party's ability to finance the proposed acquisition through
the sale of stock. Specifically, the closing sale price of Other Party's common
stock declined by 24% from August 21, when it withdrew its August 11 offer, to
September 4, the most recent trading day before September 6.

Robertson Stephens advised the ISD Board that, although it had contacted
three companies that Robertson Stephens had identified as other potential
acquirers of the Company, none had shown any interest in pursuing discussions
with ISD regarding a possible business combination. Robertson Stephens also
advised the Board that, since Winbond filed Amendment No. 2 to its Schedule 13D
on July 24, 1998, no potential acquirer had contacted or approached Robertson
Stephens concerning a possible business combination with the Company except
Winbond and Other Party.

On September 8, 1998, at a special meeting of the ISD Board, management
reviewed the possible benefits and risks relating to the proposed Merger and the
directors reviewed the principal terms of the proposed Merger Agreement. Also
present at the meeting were representatives of ISD's legal counsel. After
discussion of the remaining issues with respect to Winbond's offer, the ISD
Board approved the principal terms of the Merger Agreement and the proposed
Merger.

On September 10, 1998, Robertson Stephens delivered the Robertson Stephens
Opinion to the ISD Board that, as of the date of such opinion and subject to
certain matters and exceptions set forth in the Robertson Stephens Opinion, the
Cash Consideration to be received by Holders of ISD Common Stock in the Merger
was fair to such holders from a financial point of view. See "Approval of the
Merger -- Opinion of ISD's Financial Advisor." Resolutions of the ISD Board
dated as of September 8, 1998, approving the final terms of the Merger Agreement
and the Merger were approved by the unanimous written consent of the members of
the ISD Board on September 10 and 11, 1998.

On September 11, 1998, after the approvals by the ISD Board and the
Winbond, WIC, Oriole and Merger Sub boards of directors of the Merger Agreement
and the transactions contemplated by the Merger Agreement, the parties executed
and delivered the Merger Agreement. The parties issued a joint press release
announcing the Merger on September 13 and 14, 1998 in the United States and
Taiwan, respectively, and on September 14, 1998, ISD and Winbond held a joint
press conference in Taipei, Taiwan to further discuss the proposed Merger.

LITIGATION RELATED TO THE MERGER AND THE EFFECT OF A MAJORITY AFFIRMATIVE VOTE

On September 17, 1998, the Abraham Action was filed against ISD, its
directors and Winbond. A copy of the complaint is attached to this Proxy
Statement as Appendix D. Mr. Abraham seeks to have the matter

20
<PAGE> 26

certified as a class action of the holders of ISD Common Stock. Mr. Abraham
alleges that the intention of the ISD Defendants to pursue the Merger is in
breach of their fiduciary duties owed to holders of ISD Common Stock to take all
necessary steps to ensure that such holders will receive the maximum value
realizable for their shares in any extraordinary transaction involving ISD. Mr.
Abraham alleges that the Winbond Defendants knowingly aided and abetted the
breaches of fiduciary duty committed by the ISD Defendants. Mr. Abraham further
alleges that the Cash Consideration to be paid in connection with the Merger
allegedly does not reflect the fair value of ISD's equity, does not offer a
control premium, is less than the consideration proposed to be paid in a
previous offer, and is less than the intrinsic value of ISD's equity. He also
alleges that the Merger is not the result of arm's length negotiation and that
it was fixed arbitrarily by ISD and agreed to by the Defendants as part of the
unlawful plan and scheme to obtain the entire ownership of ISD at the lowest
possible price. See Appendix D for a full and complete statement of Mr.
Abraham's allegations. The complaint seeks a preliminary and permanent
injunction against the Merger, rescission of the Merger if it is consummated, an
accounting for all profits realized or to be realized by the Defendants as a
result of the Merger, appointment of a committee of ISD shareholders and their
representatives to assist in the independent evaluation of any transaction for
ISD's shares, and unspecified compensatory damages and attorneys' fees. ISD is
not aware of any pending motion for a preliminary injunction or other interim
relief in connection with the Abraham Action. There has been no formal discovery
to date, although plaintiff has served a request for production of documents on
ISD. After review of the complaint and based upon its understanding of the
facts, ISD believes that the allegations of the complaint are without merit and
intends to defend the Abraham Action vigorously.

OPINION OF ISD'S FINANCIAL ADVISOR

On September 10, 1998, Robertson Stephens delivered its written opinion
(the "Robertson Stephens Opinion") to the ISD Board that, as of such date and
based on and subject to the assumptions made, matters considered and limitations
on the review set forth therein, the Cash Consideration was fair from a
financial point of view to the Holders of ISD Common Stock. No limitations were
imposed by the ISD Board on Robertson Stephens with respect to the
investigations made or procedures followed by it in furnishing its opinion. The
Cash Consideration was determined through negotiations between the managements
of ISD and Winbond. Although Robertson Stephens did assist the management of ISD
in those negotiations, it was not asked by, and did not recommend to, ISD that
any specific purchase price constituted the appropriate consideration for the
Merger. Robertson Stephens expressed no opinion as to tax consequences of the
Merger, and Robertson Stephens' opinion as to fairness of the Cash Consideration
does not take into account the particular tax status or position of any
shareholder of ISD.

THE FULL TEXT OF THE ROBERTSON STEPHENS OPINION, WHICH SETS FORTH, AMONG
OTHER THINGS, ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS ON THE REVIEW
UNDERTAKEN, IS ATTACHED HERETO AS APPENDIX B AND IS INCORPORATED HEREIN BY
REFERENCE. SHAREHOLDERS OF ISD ARE URGED TO READ THE ROBERTSON STEPHENS OPINION
IN ITS ENTIRETY. THE ROBERTSON STEPHENS OPINION WAS PREPARED AT THE REQUEST AND
FOR THE USE OF THE ISD BOARD IN ITS CONSIDERATION OF THE MERGER AND DOES NOT
CONSTITUTE A RECOMMENDATION TO SHAREHOLDERS OF ISD AS TO HOW THEY SHOULD VOTE
UPON OR TAKE ANY OTHER ACTION WITH RESPECT TO THE MERGER. THE ROBERTSON STEPHENS
OPINION IS LIMITED TO THE FAIRNESS, FROM A FINANCIAL POINT OF VIEW AND AS OF

21
<PAGE> 27

THE DATE THEREOF, TO THE HOLDERS OF ISD COMMON STOCK OF THE CASH CONSIDERATION.
THE ROBERTSON STEPHENS OPINION DOES NOT ADDRESS THE VALUE OF ANY EMPLOYEE
AGREEMENT OR OTHER ARRANGEMENT ENTERED INTO IN CONNECTION WITH THE MERGER
AGREEMENT OR THE MERGER. MOREOVER, THE ROBERTSON STEPHENS OPINION DOES NOT
ADDRESS THE RELATIVE MERITS OF THE MERGER AND THE OTHER BUSINESS STRATEGIES THAT
THE ISD BOARD HAS CONSIDERED OR MAY BE CONSIDERING OR THE DECISION OF THE ISD
BOARD TO PROCEED WITH THE MERGER. THE SUMMARY OF THE ROBERTSON STEPHENS OPINION
SET FORTH IN THIS PROXY STATEMENT IS A SUMMARY OF THE MATERIAL PROVISIONS OF THE
ROBERTSON STEPHENS OPINION AND IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE
FULL TEXT OF THE ROBERTSON STEPHENS OPINION ATTACHED HERETO AS APPENDIX B.

In connection with the preparation of the Robertson Stephens Opinion,
Robertson Stephens, among other things, (i) reviewed certain financial
information furnished to it by ISD, including certain internal financial
analyses, forecasts and projections for ISD prepared by the management of ISD;
(ii) reviewed certain publicly available information concerning ISD; (iii) held
discussions with the management of ISD concerning the businesses, past and
current operations, financial condition and future prospects of ISD; (iv)
reviewed a draft dated September 9, 1998 of the Merger Agreement (the "Draft
Agreement"); (v) reviewed the share price and trading history of the ISD Common
Stock; (vi) reviewed the valuations of publicly traded companies that it deemed
comparable to ISD; (vii) compared the financial terms of the Merger with the
financial terms, to the extent publicly available, of other transactions that it
deemed relevant; and (viii) made such other studies and inquiries, and reviewed
such other data, as it deemed relevant. ISD is of the view that for purposes of
the Robertson Stephens Opinion the terms of the Draft Agreement were nearly
identical to those of the Merger Agreement.

In connection with rendering the Robertson Stephens Opinion, Robertson
Stephens assumed and relied upon the accuracy and completeness of all
information provided to it (including information provided to Robertson Stephens
orally or otherwise discussed with Robertson Stephens by management of ISD) or
publicly available and neither attempted independently to verify, nor assumed
responsibility for verifying, any of such information. Robertson Stephens relied
upon the assurances of the management of ISD that they were not aware of any
facts that would make such information inaccurate or misleading. Furthermore, it
did not obtain or make, or assume any responsibility for obtaining or making,
any independent evaluation or appraisal of any of the properties, assets or
liabilities (contingent or otherwise) of ISD, nor was it furnished with any such
evaluation or appraisal. With respect to the financial forecasts and projections
(and the assumptions and bases therefor) of ISD reviewed by Robertson Stephens,
upon the advice of management of ISD, Robertson Stephens assumed that such
forecasts and projections were reasonably prepared in good faith on the basis of
reasonable assumptions and reflect the best currently available estimates and
judgments of ISD as to the future financial performance of ISD, and that such
forecasts and projections will be realized in the amounts and in the time
periods currently estimated by the management of ISD. Robertson Stephens has
also assumed that the Merger will be consummated on the terms described in the
Draft Agreement without material alteration thereof. Robertson Stephens relied
as to all legal matters relevant to rendering its opinion on the advice of
counsel.

The Robertson Stephens Opinion is necessarily based upon market, economic
and other conditions as in effect on, and information made available to
Robertson Stephens as of, the date of the Robertson Stephens Opinion. It should
be understood that subsequent developments may affect the conclusion expressed
in the Robertson Stephens Opinion and that Robertson Stephens disclaims any
undertaking or obligation to advise the ISD Board or any other person of any
change in any fact or matter affecting the Robertson Stephens Opinion which may
come or be brought to Robertson Stephens' attention after the date of the
Robertson Stephens Opinion.

The following paragraphs summarize the material analyses performed by
Robertson Stephens in arriving at its opinion, but do not purport to be a
complete description of the analyses performed by Robertson Stephens.

Comparable Company Analysis. Using publicly available information and
estimates of ISD management, Robertson Stephens analyzed the market values plus
net debt (the "Total Capitalization") and trading multiples of ISD and the
following selected publicly traded companies in the semiconductor industry:
Catalyst Semiconductor, Inc.; Elantec Semiconductor, Inc.; IMP, Inc.; Integrated
Circuit Systems, Inc.; Integrated Silicon Solution, Inc.; Micro Linear
Corporation; Pericom Semiconductor Corporation; Quality Semiconductor, Inc.;
SEEQ Technology Incorporated; Silicon Storage Technology, Inc.; Telcom
Semiconductor, Inc.; and Xicor, Inc. (together, the "Comparable Companies").
Multiples compared by Robertson Stephens included Total Capitalization to net
revenues for calendar 1997 and the latest twelve months (the "LTM") and
estimated net revenues for calendar 1998 and 1999 ("Revenue Multiples"). All
multiples were based on closing stock prices as of September 4, 1998. Such
analysis resulted in Revenue Multiples for the Comparable Companies of
approximately (0.1)x to 0.9x and (0.1)x to 0.6x for calendar 1997 and the LTM,
respectively, and approximately 0.2x to 0.6x and 0.2x and 0.5x for calendar 1998
and 1999, respectively. Applying the Revenue Multiples for the Comparable
Companies to ISD's net revenues for calendar 1997 and the LTM and to ISD's
estimated net revenues for calendar 1998 and 1999 resulted in implied per share
equity value reference ranges for ISD of approximately $2.45 to $6.93 for
calendar 1997, $2.31 to $6.03 for the LTM, $3.70 to $5.80 for calendar 1998 and
$3.62 to $5.59 for calendar 1999. Robertson Stephens also analyzed the Revenue
Multiples and similar trading multiples of ISD and the Comparable Companies for
similar periods applying acquisition premiums to the multiples. Robertson
Stephens applied a 20% premium to the low multiple, a 40% premium to the high
multiple and a 30% premium to the average multiple for each period. Such
analysis resulted in Revenue Multiples (adjusted for acquisition premiums) for
the Comparable Companies of approximately 0.0x to 1.3x and 0.0x to 0.9x for
calendar 1997 and the LTM, respectively, and approximately 0.2x to 0.9x and 0.2x
and 0.7x for calendar 1998 and 1999, respectively. Applying the Revenue
Multiples (adjusted for acquisition premiums) for the Comparable Companies to
ISD's net revenues for calendar 1997 and the LTM and to ISD's estimated net
revenues for calendar 1998 and 1999 resulted in implied per share equity value
reference ranges for ISD of approximately $2.78 to $8.61 for calendar 1997,
$2.81 to $7.36 for the LTM, $3.89 to $7.03 for calendar 1998 and $3.80 to $6.73
for calendar 1999.

Precedent Transaction Analysis. Using publicly available information,
Robertson Stephens analyzed the aggregate value and implied transaction value
multiples paid or proposed to be paid in selected merger or acquisition
transactions in the semiconductor industry (the "Semiconductor Comparable
Transactions"). Robertson Stephens compared, among other things, the premiums
paid in the Semiconductor Comparable Transactions relative to the closing
trading price of the acquired companies' common stock one day and one month
prior to the public announcement of such transactions. Applying a range of
acquisition premiums of 0.0% to 40.0% to the one-day prior price and 20.0% to
60.0% to the one-month prior price, in each case prior to the public
announcement of the consideration of an acquisition transaction, resulted in
implied per share equity value reference ranges of $5.13 to $7.18 and $6.30 to
$8.40, respectively. Robertson Stephens also analyzed premiums paid in selected
merger or acquisition transactions during calendar years 1995, 1996, 1997 and
1998 in the broader technology sector (the "Technology Comparable Transactions,"
and together with the Semiconductor Comparable Transactions, the "Comparable
Transactions") relative to the closing trading price of the acquired companies'
common stock one day and one month prior to the public announcement of such
transactions. The aggregate mean premiums based on the one-day and one-month's
prior price for all years were 31.2% and 33.6%, respectively, which implied per
share equity values for ISD of approximately $6.72 and $7.01, respectively.

All multiples for the Comparable Companies and the Comparable Transactions
were based on public information available at the time of the announcement of
such transactions, without taking into account differing market and other
conditions during the period in which the Comparable Companies and the
Comparable Transactions occurred. No company, transaction or business used in
the Comparable Company Analysis or the Precedent Transaction Analysis as a
comparison is identical to ISD, Winbond or the Merger. Accordingly, an analysis
of the results of the foregoing is not entirely mathematical; rather it involves
complex considerations and judgments concerning differences in financial and
operating characteristics and other factors that could affect the acquisition,
public trading and other values of the Comparable Companies, the Comparable
Transactions or the business segment, company or transactions to which they are
being compared.

Discounted Cash Flow Analysis. Robertson Stephens performed a discounted
cash flow analysis of the unlevered (before interest expense) after-tax cash
flows of ISD using estimates prepared by the management of ISD. Robertson
Stephens discounted the projected net cash flows through December 31, 2003,
using discount ranges ranging from 20.0% to 24.0%. Robertson Stephens then added
to the present value of the cash flows an estimated terminal value of ISD at
December 31, 2003, discounted back at the same range of discount rates. The
terminal value was computed by multiplying ISD's projected revenue in the fiscal
year ending December 31, 2003 by terminal multiples ranging from 0.8x to 1.0x.
The discounted cash flow analysis indicated implied per share equity valuations
for ISD ranging from $5.56 to $6.94.

While the foregoing summary describes the material analyses and factors
that Robertson Stephens considered in rendering the Robertson Stephens Opinion
to the ISD Board, it is not a comprehensive description of all analyses and
factors considered by Robertson Stephens. The preparation of a fairness opinion
is a complex process that involves various determinations as to the most
appropriate and relevant methods of financial analysis and the application of
these methods to the particular circumstances and, therefore, such an opinion is
not readily susceptible to partial analysis or summary description. In arriving
at its opinion, Robertson Stephens did not attribute any particular weight to
any analysis or factor considered by it, but rather made qualitative judgments
as to the significance and relevance of each analysis and factor. Accordingly,
Robertson Stephens believes that its analyses must be considered as a whole and
that selecting portions of its analyses and of the factors considered by it,
without considering all analyses and factors, could create a misleading or
incomplete view of the evaluation process underlying its opinion. Several
analytical methodologies were employed and no one method of analysis should be
regarded as critical to the overall conclusion reached by Robertson Stephens.
Each analytical technique has inherent strengths and weaknesses, and the nature
of the available information may further affect the value of particular
techniques. The conclusion reached by Robertson Stephens is based on all
analyses and factors taken as a whole and also on application of Robertson
Stephens' own experience and judgment. Such conclusion may involve significant
elements of subjective judgment and qualitative analysis. Robertson Stephens
therefore gives no opinion as to the value or merit standing alone of any one or
more parts of the analysis it performed. In performing its analyses, Robertson
Stephens made numerous assumptions with respect to industry performance, general
business and other conditions and matters many of which are beyond the control
of ISD. Any estimates contained in these analyses are not necessarily indicative
of actual values or predicative of future results or values, which may be
significantly more or less favorable than those suggested by such analyses.
Accordingly, analyses relating to the value of businesses do not purport to be
appraisals or to reflect the prices at which such businesses actually may be
sold in the future, and such estimates are inherently subject to uncertainty.

ISD engaged Robertson Stephens pursuant to a letter agreement dated July 8,
1998 (the "Robertson Stephens Engagement Letter"). The agreement provides that,
for its services, Robertson Stephens is entitled to receive, contingent upon
consummation of the Merger, a transaction fee equal to $500,000 plus 1.25%
percent of the Aggregate Transaction Value (as defined in the agreement) in
excess of $50.0 million. Pursuant to the Robertson Stephens Engagement Letter
Robertson Stephens was paid $250,000 upon delivery of its opinion, which opinion
fee will be credited against the transaction fee. ISD has also agreed to
reimburse Robertson Stephens for its out-of-pocket expenses and to indemnify and
hold harmless Robertson Stephens and its affiliates and any other person,
director, employee or agent of Robertson Stephens or any of its affiliates, or
any person controlling Robertson Stephens or its affiliates for certain losses,
claims, damages, expenses and liabilities relating to or arising out of services
provided by Robertson Stephens as financial advisor to ISD. The terms of the fee
arrangement with Robertson Stephens, which ISD and Robertson Stephens believe
are customary in transactions of this nature, were negotiated at arm's length
between ISD and Robertson Stephens, and the ISD Board was aware of such fee
arrangements.

Robertson Stephens was retained based on Robertson Stephens' experience as
a financial advisor in connection with mergers and acquisitions and in
securities valuations generally, as well as Robertson Stephens' investment
banking relationship and familiarity with ISD. Robertson Stephens has provided
financial advisory and investment banking services to ISD from time to time,
including acting as co-managing underwriter for ISD's initial public offering in
1995 and as a co-managing underwriter for a follow-on offering, which also took
place in 1995.

Robertson Stephens is a nationally recognized investment banking firm. As
part of its investment banking business, Robertson Stephens is frequently
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. Robertson Stephens may
actively trade the equity of ISD for its own account and for the account of its
customers and, accordingly, may at any time hold a long or short position in
such securities.

MATERIAL US FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

The receipt of cash for shares of ISD Common Stock in the Merger will be a
taxable transaction for United States federal income tax purposes and may also
be a taxable transaction under applicable state, local or foreign tax laws. In
general, a shareholder will recognize gain or loss for United States federal
income tax purposes equal to the difference between the amount of cash received
in exchange for each share sold and such shareholder's adjusted tax basis in
such share. Assuming the shares of ISD Common Stock constitute capital assets in
the hands of the shareholder at the time of the Merger, such gain or loss will
be capital gain or loss. If, at the time of the Merger, the shares of ISD Common
Stock then exchanged have been held for more than 12 months, such gain or loss
will be a long-term capital gain or loss. Under current law, long-term capital
gains of individuals are, under certain circumstances, taxed at lower rates than
items of ordinary income and short-term capital gains.

THE FOREGOING DISCUSSION MAY NOT APPLY TO CERTAIN TYPES OF SHAREHOLDERS,
INCLUDING SHAREHOLDERS WHO ACQUIRED SHARES PURSUANT TO THE EXERCISE OF EMPLOYEE
STOCK OPTIONS OR OTHERWISE AS COMPENSATION, INDIVIDUALS WHO ARE NOT CITIZENS OR
RESIDENTS OF THE UNITED STATES, FOREIGN CORPORATIONS AND OTHER TAXPAYERS WHOSE
UNIQUE SITUATION REQUIRE SPECIAL ANALYSES.

THE DISCUSSION OF MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF
THE MERGER SET FORTH ABOVE IS BASED UPON PRESENT LAW. SHAREHOLDERS ARE URGED TO
CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE SPECIFIC TAX CONSEQUENCES OF
THE MERGER TO THEM, INCLUDING THE APPLICATION AND EFFECT OF THE ALTERNATIVE
MINIMUM TAX, AND STATE, LOCAL AND FOREIGN TAX LAWS.

ACCOUNTING TREATMENT

GOVERNMENT AND REGULATORY APPROVALS

Under the HSR Act and the rules promulgated under the HSR Act by the FTC,
the Merger cannot be effected until notifications have been given to the FTC,
and the specified waiting period has expired or terminated early. All required
filings under the HSR Act have been made. Effective October 6, 1998, the FTC
granted requests for early termination of the waiting period under the HSR Act.
Winbond has received all required R.O.C. government and regulatory approvals.

At any time before or after the Effective Date of the Merger, and
notwithstanding the expiration of the applicable waiting periods under the HSR
Act and other applicable antitrust laws, the U.S. Department of Justice, the FTC
or any state or foreign governmental authority could take such action under the
antitrust laws as it deems necessary or desirable in the public interest. Such
action could include seeking to enjoin the effectuation of the Merger, seeking
divestiture by Winbond or its affiliates of ISD or businesses of Winbond, its
affiliates or ISD, or seeking to impose conditions on the combined company with
respect to its business. Private parties may also seek to take legal action
under the antitrust laws under certain circumstances.

DISSENTERS' RIGHTS

The record holders of the shares of ISD Common Stock that are eligible to,
and do, exercise their dissenters' rights with respect to the Merger are
referred to herein as "Dissenting Shareholders," and the shares of stock with
respect to which they may exercise dissenters' rights are referred to herein as
"Dissenting Shares." If an ISD shareholder has a beneficial interest in shares
of ISD Common Stock that are held of record in the name of another person, such
as a broker or nominee, and such shareholder desires to perfect whatever
dissenters' rights such beneficial shareholder may have, such beneficial
shareholder must act promptly to cause the holder of record timely and properly
to follow the steps summarized below.

The following discussion of the material provisions of the CGCL relating to
dissenters' rights is qualified in its entirety by reference to Sections 1300
through 1312 of the CGCL attached to this Proxy Statement as Appendix C and
incorporated herein by this reference. This discussion and Sections 1300 through
1312 of the CGCL should be reviewed carefully by any ISD shareholder who wishes
to exercise statutory dissenters' rights or wishes to preserve the right to do
so, since failure to comply with the required procedures will result in the loss
of such rights.

Shares of ISD Common Stock must satisfy each of the following requirements
to qualify as Dissenting Shares under the CGCL: (i) such shares of ISD Common
Stock must have been outstanding on the Record Date; (ii) such shares of ISD
Common Stock must have been voted against the Merger; (iii) the holder of such
shares of ISD Common Stock must make a written demand that ISD repurchase such
shares of ISD Common Stock at fair market value and such demand must be received
by either ISD or ISD's transfer agent no later than the date of the Special
Meeting; and (iv) the holder of such shares of ISD Common Stock must submit
certificates for endorsement (as described below). A vote by proxy or in person
against the Merger does not in and of itself constitute a demand for payment
under the CGCL. In addition, for such shares of ISD Common Stock to qualify as
Dissenting Shares, (i) demands for payment must have been filed with respect to
5% or more of the outstanding shares of ISD Common Stock on or before the date
of the Special Meeting or (ii) such shares of ISD Common Stock must be subject
to restriction on transfer imposed by ISD or by any law or regulation.

Pursuant to Sections 1300 through 1312 of the CGCL, Dissenting Shareholders
may require ISD to repurchase their Dissenting Shares at a price equal to the
fair market value of such shares determined as of the day before the first
announcement of the terms of the Merger, excluding any appreciation or
depreciation in consequence of the Merger, but adjusted for any stock split,
reverse stock split or stock dividend that becomes effective thereafter. On
September 11, 1998, the last full day of trading prior to the public
announcement of the proposed Merger, the closing price per share of ISD Common
Stock was $6.6875.

The demand of a Dissenting Shareholder must be made in writing upon ISD no
later than the date of the Special Meeting. Such demand is required by law to
state the number and class of Dissenting Shares held of record by the Dissenting
Shareholder that the Dissenting Shareholder demands that ISD purchase, and the
amount that the Dissenting Shareholder claims to be the fair market value of the
Dissenting Shares as of the day before the first announcement of the Merger. The
statement of fair market value in such demand by the Dissenting Shareholder
constitutes an offer by the Dissenting Shareholder to sell the Dissenting Shares
at such price.

26
<PAGE> 32

If there are any Dissenting Shareholders, then within 10 days after
approval of the Merger by the outstanding shares of ISD Common Stock, ISD is
required to mail to each holder of Dissenting Shares a notice of the approval of
the Merger, a statement of the price determined by ISD to represent the fair
market value of Dissenting Shares (which shall constitute an offer by ISD to
purchase such Dissenting Shares at such stated price) and a description of the
procedures to be followed for such shareholders to exercise their rights as
Dissenting Shareholders.

Within 30 days after the date on which the notice of the approval of the
Merger by the outstanding shares was mailed to a Dissenting Shareholder, that
shareholder who wishes to be paid the full value of his or her Dissenting Shares
must submit to ISD or its transfer agent certificates representing any
Dissenting Shares that the Dissenting Shareholder demands ISD purchase, so that
the certificate for such Dissenting Shares may either be stamped or endorsed
with the statement that the shares are Dissenting Shares or exchanged for
certificates of appropriate denomination so stamped or endorsed.

If, upon a Dissenting Shareholder's surrender of the certificates
representing that Dissenting Shareholder's Dissenting Shares, ISD and the
Dissenting Shareholder agree that such shares are Dissenting Shares and agree
upon the price to be paid for such shares, then the agreed price is required by
law to be paid to the Dissenting Shareholder within the later of 30 days after
the date of such agreement or 30 days after any statutory or contractual
conditions to the consummation of the Merger are satisfied, unless provided
otherwise by agreement.

If ISD and a Dissenting Shareholder disagree as to whether such Dissenting
Shareholder's proposed Dissenting Shares are entitled to be classified as
Dissenting Shares or as to the fair market value of such shares, then such
Dissenting Shareholder has the right to bring an action in California Superior
Court, within six months after the date on which the notice of the approval of
the Merger by the outstanding shares of ISD Common Stock was mailed to the
Dissenting Shareholder, to resolve such dispute. In such action, the court will
determine whether the shares of ISD Common stock held by such Dissenting
Shareholder are Dissenting Shares, the fair market value of such shares, or
both. The CGCL provides, among other things, that a Dissenting Shareholder may
not withdraw a demand for payment of the fair market value of Dissenting Shares
unless ISD consents to such request for withdrawal. Any payments made in respect
of Dissenting Shares will be made by ISD.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

In considering the recommendation of the ISD Board with respect to the
Merger Agreement, ISD shareholders should be aware that certain members of the
Company's management (as well as other employees of the Company) may receive
certain direct or indirect benefits in connection with the Merger Agreement and
the transactions contemplated thereby, as described herein, that are different
from, or in addition to, the interests of holders of shares of ISD Common Stock.

In January 1996, the Company entered into Employment Agreements with David
L. Angel, Chairman of the Board and Chief Executive Officer and Felix J.
Rosengarten, Vice President, Finance and Administration and Chief Financial
Officer. In November 1996, the Company entered into an Employment Agreement with
Eric J. Ochiltree, President and Chief Operating Officer, and amended Mr.
Angel's and Mr. Rosengarten's Employment Agreements (as amended, the "Employment
Agreements"). Under the terms of the Employment Agreements, in the event of a
corporate transaction, such executive officer shall be entitled to the following
compensation and benefits: (i) a lump sum payment equal to 2 1/2 years of pay at
the employee's gross base annual salary rate and (ii) the acceleration of all of
the employee's unvested outstanding stock options under the Company's 1987 Stock
Option Plan and/or 1994 Equity Incentive Plan.

The term "corporate transaction" is defined in the Employment Agreements
as: (i) a merger or acquisition in which ISD is not the surviving entity (except
for a merger of ISD into a wholly-owned subsidiary, and except for a transaction
the purpose of which is to change the state in which ISD is incorporated); (ii)
the sale, transfer or other disposition of all or substantially all of the
assets of ISD; or (iii) any other corporate reorganization or business
combination, in which beneficial ownership of 50% or

27
<PAGE> 33

more of ISD's outstanding voting stock is transferred. The consummation of the
transactions contemplated by the Merger Agreement constitutes a corporate
transaction for purposes of the Employment Agreements.

The current annual salary of each of the above executive officers is as
follows: $249,000 for Mr. Angel; $225,000 for Mr. Ochiltree; and $163,000 for
Mr. Rosengarten.

In connection with the Merger, all options granted under the ISD Option
Plans will accelerate and become exercisable in full. Pursuant to the Merger
Agreement, ISD will purchase such options immediately prior to the effective
time of the Merger. The amount to be received by each executive officer of ISD
in exchange for such options is as follows: David L. Angel, $131,982; Eric J.
Ochiltree, $232,141; Felix J. Rosengarten, $56,696; James Brennan, $36,944; Carl
R. Palmer, $51,223; Karen L. Bootsma, $49,535; Michael Geilhufe, $41,008; P.
Ross Hayden, $68,858; Alfred R. Woodhull, $42,079; and Avi Barel, $60,088. The
amount to be received by each member of the ISD Board (excluding Messrs. Angel
and Ochiltree) in exchange for such person's options is as follows: Frederick B.
Bamber, $11,955; Eugene J. Flath, $11,955; Alan V. King, $13,830 and Frederick
L. Zieber, $11,955. The aggregate purchase price of the options held by all
other employees of ISD as a group is $1,186,208. See "Terms of the
Merger -- Manner and Basis of Transferring Shares; Treatment of Options" and
"Security Ownership of ISD Directors, Officers and Principal Shareholders."

In addition to the foregoing, certain ISD management personnel (including
the above referenced individuals) may enter into employment agreements or
arrangements with Winbond that will become effective on or after consummation of
the Merger. Also, certain of the three ISD executive officers identified above
may seek to have ISD modify his Employment Agreement (subject to the approval of
Winbond as required under the Merger Agreement) to minimize his tax obligations
as a result of the Merger. In addition, Winbond expects to propose key employee
retention incentive plans and modified compensation packages payable over two
years. The additional compensation offered through these arrangements will be
payable based on continued service and, in some cases, on the achievement of
performance objectives, and could materially increase the benefits of the Merger
to the participating employees, including senior management personnel of ISD.
Winbond anticipates that the aggregate amount of such additional compensation
payable to all participating employees would be at least $4.0 million. As a
result of the foregoing, certain officers and employees of ISD may have personal
interests in the Merger which are not identical to the interests of other ISD
shareholders.

TERMS OF THE MERGER

The following discussion summarizes the material terms of the Merger
Agreement and the transactions contemplated thereby. The following is not,
however, a complete statement of all provisions of the Merger Agreement and
related agreements. The following description of the Merger, the Merger
Agreement and related transactions is qualified in all respects by reference to
the complete text of the Merger Agreement which is attached to this Proxy
Statement as Appendix A.

EFFECTIVE TIME; CLOSING DATE

Subject to the provisions of the Merger Agreement, Winbond, WIC, Oriole,
Merger Sub and ISD will effect the Merger by filing the required documents with
the Secretary of State of the State of California in accordance with the CGCL.
The Merger will become effective upon such filing (the "Effective Time of the
Merger"). The closing of the Merger (the "Closing") will take place as soon as
practicable on the later of (i) the date of the Special Meeting or (ii) the
first business day after satisfaction of the latest to occur of the conditions
to the Merger, unless Winbond and ISD agree in writing on another date. The
parties anticipate that the Closing will occur on or about December 22, 1998.

MANNER AND BASIS OF TRANSFERRING SHARES; TREATMENT OF OPTIONS

At the Effective Time of the Merger, ISD will continue as the Surviving
Company and will become a wholly-owned subsidiary of Oriole. By virtue of the
Merger and without any action on the part of the holder of any shares of ISD
Common Stock, each issued and then outstanding share of ISD Common Stock (other
than shares owned by WIC, Oriole, Merger Sub, any member of the Winbond Group or
any other subsidiary of Winbond and any shares of ISD Common Stock that are held
by shareholders who have demanded properly in writing dissenters' rights with
respect to such shares in accordance with the CGCL) shall be automatically
converted into the right to receive $7.50, in cash, without interest (the "Cash
Consideration").

Pursuant to the Merger Agreement, all outstanding shares of capital stock
of Merger Sub issued and outstanding at the Effective Time of the Merger will be
converted into 1,000 shares of Common Stock of the Surviving Company.

Pursuant to the Merger Agreement, ISD has agreed to use its best efforts to
deliver to Winbond, before the Closing, consents in writing from the holders of
all options outstanding on such date that had been granted before the date of
the Merger Agreement pursuant to the ISD Option Plans, pursuant to which such
holders consent to the purchase of their options by ISD immediately prior to the
Effective Time of the Merger. The purchase price of each such option will be an
amount (less any applicable withholding taxes) equal to the excess, if any, of
the Cash Consideration over the per share exercise price of such option,
multiplied by the number of shares of ISD Common Stock underlying such option
immediately before the Effective Time of the Merger.

Pursuant to the Merger Agreement, the ISD 1994 Employee Stock Purchase Plan
will terminate at the Effective Time of the Merger.

The Cash Consideration will be proportionately reduced under a formula
specified in the Merger Agreement if (i) ISD grants options or issues additional
shares of ISD Common Stock before the Effective Time of the Merger, in excess of
amounts permitted under the Merger Agreement, without the consent of Winbond as
required by the Merger Agreement, and (ii) such options are purchased by ISD
and/or such shares are entitled to payment from Winbond as a part of the Merger.
The Merger Agreement permits an aggregate of 12,590,703 shares subject to
outstanding options to be purchased under the Merger Agreement and shares
outstanding. As of the Record Date, there were options to purchase an aggregate
of 2,126,513 shares of Common Stock that would be purchased by ISD prior to the
Merger and 9,958,194 shares of ISD Common Stock outstanding. As a result, ISD
must issue at least 505,996 additional shares of ISD Common Stock or options to
purchase ISD Common Stock to require a reduction in the Cash Consideration under
the Merger Agreement. The Company will not grant options or issue shares in
numbers sufficient to cause the Cash Consideration to be reduced pursuant to the
Merger Agreement. In such event, however, ISD will resolicit proxies for the
Special Meeting.

SURRENDER AND EXCHANGE OF CERTIFICATES

CONDUCT OF ISD'S BUSINESS BEFORE THE MERGER

In addition, except as permitted by the Merger Agreement, ISD has agreed
that it will not do any of the following without the prior written consent of
Winbond:

- amend its Articles of Incorporation or Bylaws;

- authorize for issuance, issue, deliver or sell any additional shares of
its capital stock of any class (except upon the exercise of options
existing as of the date of the Merger Agreement), or securities
convertible into shares of such stock, or issue or grant any rights,
options or other commitments for the issuance of shares of such stock or
such convertible securities or accelerate the vesting date of any such
rights, options or other commitments, except that ISD may, in the
ordinary course of business, grant options under its 1994 Equity
Incentive Plan to new employees hired in accordance with ISD's covenants
in the Merger Agreement, so long as the total number of options
outstanding under the 1994 Equity Incentive Plan does not exceed the
total number of shares reserved for issuance under such plan as of August
19, 1998;

- split, combine or reclassify any shares of its capital stock or declare,
set aside or pay any dividend or other distribution (whether in cash,
stock or property) in respect of its capital stock or purchase or redeem
or otherwise acquire any of its capital stock;

- dispose of or acquire any material properties or assets, except in the
ordinary course of business;

- engage in any activities or transactions that are outside the ordinary
course of ISD's business or which could reasonably be anticipated to
materially adversely affect ISD's business or assets;

- enter into or materially amend any consulting agreement or employment
agreement or increase the compensation payable or to become payable by
ISD to any of its officers, employees or agents over the amounts payable
as of December 31, 1997, or adopt or materially amend any employee
benefit plan or arrangement, other than agreements, increases or
amendments in the ordinary course of business or required by law;

- extend offers of employment or hire any new employees or consultants,
other than in the ordinary course of business consistent with past
practice;

- incur any indebtedness, other than in the ordinary course of business; or

- authorize or make any capital expenditure in excess of $25,000, other
than in the ordinary course of business consistent with past practice and
ISD's capital expenditure budget.

ISD has also agreed in the Merger Agreement to notify Winbond of (a) any
notice of default received by ISD under any material contract which, if not
remedied, would result in any material adverse change in the operations,
financial condition or business of ISD taken as a whole or which would render
incorrect any

30
<PAGE> 36

representation made by ISD in the Merger Agreement; and (b) any suit, action or
proceeding instituted or, to the knowledge of ISD, threatened against or
affecting ISD which, if adversely determined could reasonably be expected to
result in any material adverse change in the financial condition or business of
ISD taken as a whole, or which would render incorrect any representation made by
ISD in the Merger Agreement.

Pursuant to the Merger Agreement, ISD has agreed that it will terminate the
Rights Agreement between ISD and The First National Bank of Boston as Rights
Agent, without any rights thereunder becoming exercisable with respect to the
Merger.

The Merger Agreement contains additional covenants and agreements of the
parties, including covenants and agreements relating to: (a) access to
information concerning ISD and confidentiality of the parties' business
information; (b) the obligations of the parties to make certain governmental
filings, including filings with the FTC and the Taiwan Foreign Investment
Committee; (c) the obligations of ISD with respect to the Special Meeting; (d)
public statements with respect to the Merger; (e) third party consents and
approvals; (f) mutual indemnification of the parties for any broker's or
finder's fees; and (g) receipt by Winbond at the Effective Time of the Merger of
a comfort letter from ISD's independent auditors.

EXCLUSIVITY

Until the earlier of the Closing or the date of termination of the Merger
Agreement, ISD has agreed that it will not and will not authorize or permit any
of its officers, directors, agents, representatives or affiliates, directly or
indirectly, to take any of the following actions: (i) solicit, initiate,
entertain, encourage, participate in, conduct discussions with or engage in
negotiations with any person relating to any Acquisition Proposal (as defined
below); (ii) provide any written or oral information with respect to ISD to any
person (other than as contemplated in the Merger Agreement or required by
applicable law) relating to any Acquisition Proposal; or (iii) enter into any
agreement with any person with regard to any Acquisition Proposal. However,
nothing contained in the Merger Agreement shall prevent ISD or the ISD Board
from (A) complying with Rule 14e-2 promulgated under the Exchange Act with
regard to an Acquisition Proposal; (B) engaging in any discussion or
negotiations with, or providing any information to, any person in response to an
unsolicited bona fide written Acquisition Proposal by any such person; or (C)
recommending such an unsolicited bona fide written Acquisition Proposal to the
ISD shareholders or withdrawing or modifying its recommendation in favor of the
Merger Agreement and the Merger in compliance with the Merger Agreement, if and
only to the extent that, in any such case as is referred to in clause (B) or
(C), (I) a majority of the members of the ISD Board concludes in good faith
(after consultation with its financial advisors) that such Acquisition Proposal
is reasonably capable of being completed, taking into account all legal,
financial, regulatory and other aspects of the proposal and the person making
the proposal, and would, if consummated, result in a transaction more favorable
to ISD's shareholders than the transaction contemplated by the Merger Agreement
(a "Superior Proposal"); (II) a majority of the members of the ISD Board
concludes in good faith (after consultation with outside counsel) that such
action is necessary for the ISD Board to act in a manner consistent with its
fiduciary duties under applicable law; (III) prior to providing any information
or data to any person in connection with an Acquisition Proposal by any such
person, the ISD Board receives from such person an executed confidentiality
agreement on terms substantially similar to those contained in the
confidentiality agreement previously entered into between Winbond and ISD in
connection with their consideration of the Merger; and (IV) prior to providing
any information or data to any person or entering into discussions or
negotiations with any person, the ISD Board notifies Winbond of such inquiries,
expressions of interest, proposals or offers received by, and any such
information requested from, or any such discussions or negotiations to be
initiated or continued with, any of ISD's representatives indicating, in
connection with such

Merger; (c) Winbond terminates the Merger Agreement because (i) the ISD Board
has withdrawn or modified its recommendation in favor of the Merger Agreement
and the Merger or (ii) before the Special Meeting, a tender offer other than by
Winbond or its affiliates has commenced and the ISD Board has not recommended
against acceptance of such tender offer within the time period required by the
regulations of the Commission; or (d) ISD terminates the Merger Agreement
because the ISD Board has determined in good faith that an Acquisition Proposal
has become a Superior Proposal.

The Merger Agreement provides that if the Closing does not occur before
December 31, 1998 because Winbond or ISD has breached its obligations to satisfy
the conditions to Closing specified in the Merger Agreement, the breaching party
must pay $4.0 million to the other. No fee is payable by Winbond, WIC, Peaceful
River Corp. or Pigeon Creek Holding Co., Ltd. if the failure to close is due to
a material adverse change in the financial condition, results of operations or
business of ISD after September 11, 1998, as determined in good faith by the
Winbond board of directors. No fee is payable by any party if the failure to
close before December 31, 1998 is due to any of the following: (i) the
Department of Justice and/or the Federal Trade Commission has not given written
notice of the expiration of the HSR Act waiting period or has notified ISD or
Winbond of its or their intention to take action to stop or delay the Merger;
(ii) litigation or other similar action seeking to enjoin or otherwise stop or

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

This Management's Discussion and Analysis of Financial Condition and
Results of Operations contains forward-looking statements that reflect ISD's
current views with respect to future matters such as gross margins, spending
levels, international operations, gross profit and capital needs. Actual results
may differ materially from the results and outcomes discussed in the
forward-looking statements. Factors that could cause or contribute to such
differences in results and outcomes include without limitation those discussed
below as well as those discussed elsewhere in this Proxy Statement.

OVERVIEW

ISD designs, develops, and markets semiconductor voice solutions based on
analog and digital technologies and mixed signal expertise. ISD's patented
ChipCorder and CompactSPEECH technologies enable solid state voice recording and
playback applications in the communications, consumer, industrial, and
automotive markets. ChipCorder products deliver single-chip solutions, simple
integration, exceptional sound quality, low power consumption, battery-less
voice storage, and low cost. CompactSPEECH products deliver powerful digital
speech processing, advanced telecommunication capabilities, long recording
times, cost effective high voice quality, multi-language speech synthesis, and
battery-less voice storage.

The Company distributes its products through a direct sales organization
and a worldwide network of approximately 50 sales representatives and
distributors. The Company was incorporated in California in December 1987 and
commenced production shipments in 1992. ISD is an ISO 9001 certified company.

ISD subcontracts with independent foundries to fabricate the wafers for all
of its products. This approach enables the Company to concentrate its resources
on the design, development, and marketing areas, where the Company believes it
has the greatest competitive advantage, and eliminates the high cost of owning
and operating a semiconductor wafer fabrication facility. The Company is
dependent on these foundries to allocate to the Company a portion of their
foundry capacity sufficient to meet the Company's needs, to produce products of
acceptable quality and with acceptable manufacturing yields, and to deliver
products to the Company on time. Historically, the Company has experienced
difficulties in each of these areas, and the Company expects that it could
experience such difficulties in the future.

In April 1998, the Company announced the ISD4000 family, the industry's
only single chip solution with record and playback durations up to 16 minutes.
The ISD4000 family of record and playback chips is based on SuperFlash memory
technology. The ISD4000 family, optimized for cellular phone applications,
quadruples ISD's current longest recording duration to 16 minutes. The ISD4000
family consists of three product series: the first series offers two to four
minute durations, the second series offers four to eight minute durations, and
the third series operates from eight to 16 minute durations. In September 1998,
ISD announced the availability of the ISD4004, the industry's first and only
single chip solution with a record and playback duration of up to 16 minutes.

In July 1998, the Company announced that it had received exclusive
worldwide licensing rights to embed Conversa's (Conversational Computing
Corporation) speaker-independent continuous voice recognition technology into a
new family of digital voice processors. As part of the agreement, ISD has made
an equity investment in Conversa. The licensing agreement and investment are an
expansion of the joint development agreement ISD signed with Conversa in March
1998. The new ISD voice recognition chips are expected to provide high accuracy,
continuous, or conversational, speaker independent capabilities. Products
integrating these new chips will not have to be trained and will respond to a
set of American-English commands. Additional languages are expected to be
supported at a later date.

In the third quarter of 1998, the Company transferred a substantial portion
of its wafer sort and final test manufacturing operation to AMKOR, the Company's
assembly and test subcontractor in the Philippines. This consolidation enables
ISD to ship wafers directly from its wafer foundries to AMKOR for turnkey
manufacturing and direct shipment of finished product directly to the customer.
The objective of this move is to improve manufacturing cycle time while reducing
work in process, inventory, and manufacturing cost.

36
<PAGE> 42

ISD's San Jose manufacturing group will focus on engineering, test development
and pre-production efforts for new products. The cost of the move, all of which
was incurred in the third quarter of 1998 and included in cost of goods sold,
was less than $200,000. The Company increased inventory in the second quarter of
1998 in preparation for the move to AMKOR. In the third quarter of 1998,
inventory has been reduced as planned.

On November 16, 1998, the Company announced the ISD5008, a single-chip
fully integrated voice storage solution designed for digital cellular handsets.
The ISD5008 is the newest member of ISD's ChipCorder family. It is expected to
enable quick, flexible and easy integration of voice storage features in such
products as telephone answering machines, cordless phones, automotive
communication devices, pocket recorders/PDAs, dictation devices, language
translators and music-on-hold systems. The ISD5008 eliminates external analog
circuitry such as automatic gain control (AGC), power amplifier, volume control,
and switches by integrating these on one easy-to-use chip. Samples are planned
during the first half of 1999. Given the uncertainties of product development,
there can be no assurance that the product will be produced in the anticipated
time frame or with the anticipated features and performance.

On September 11, 1998, ISD and Winbond, WIC, Oriole and Merger Sub entered
into the Merger Agreement, pursuant to which Merger Sub will merge with and into
ISD and ISD will become a wholly owned-subsidiary of Oriole. Upon consummation
of the Merger, each outstanding share of ISD Common Stock not owned by the
Winbond Group will be automatically canceled and converted into the right to
receive the Cash Consideration. The Merger is subject to the approval of the ISD
shareholders, and to certain regulatory approvals and other customary closing
conditions. All of the directors of ISD and certain of ISD's executive officers,
as well as Winbond, have executed Voting Agreements pursuant to which they have
agreed to vote for the Merger. See "Terms of the Merger."

acquisition.

COMPARISON OF YEARS ENDED DECEMBER 31, 1995, 1996 AND 1997

Net Revenues. ISD had net revenues of $47.9 million in 1997 compared to
$41.3 million for 1996, an increase of 16%. Net revenues in 1996 decreased 25%
from $55.5 million for 1995. The increase in net revenues for 1997 reflects the
acceptance of ISD's products into the growing communications market and
additional net revenues as a result of the CompactSPEECH product line
acquisition in March 1997. The decrease in net revenue in 1996 reflects
unexpected softness in the consumer market for ISD's products throughout 1996
compared to the strong demand experienced in the consumer market during 1995.
Net

37
<PAGE> 43

revenues in the communications market grew to about $38 million in 1997 compared
to about $30 million in 1996 and $28 million in 1995. Net revenues in the
consumer market accounted for about $6 million of net revenues in 1997 compared
to about $9 million in 1996 and $25 million in 1995. The growth in net revenues
for 1997 encompasses increased shipment volume of ChipCorder product as well as
the advent of the CompactSPEECH product line shipments. In 1997, as in 1996,
product volume continued to increase in the communications market but decreased
significantly in the consumer market. In 1995, net revenue reflected increased
volume of ChipCorder products sold in both the consumer and the communication
markets.

Sales by market segment for 1997 were 79% communications, 12% consumer and
9% industrial compared to 72% communications, 21% consumer and 7% industrial for
1996 and 50% communications, 45% consumer and 5% industrial for 1995. Sales in
the automotive market are included in industrial. ISD's communications customers
in 1997 continued representing such products as telephone answering machines,
cellular phones, personal handy phones and pagers. Products for consumer
customers in 1997 consisted primarily of personal memory recorders, cameras,
photo frames, books, educational toys and novelties.

Sales to ISD's top ten customers accounted for 76% of net revenues in 1997
compared to 85% in 1996 and 66% in 1995. The top five customers in 1997 were
Marubun (ISD's Japanese distributor), Motorola, Matsushita, Philips, and
NuHorizons (ISD's United States distributor), accounting for 19%, 17%, 13%, 11%,
and 7% of net revenues, respectively. ISD expects that sales of its products to
a limited number of customers will continue to account for a substantial portion
of its revenues for the foreseeable future. ISD has also experienced changes in
the composition of its customer base from year to year and expects this pattern
to continue. The loss of, or significant reduction in purchases by, current
major customers, would have a material adverse effect on ISD's business,
financial condition and results of operations. ISD's customers typically do not
contract for minimum purchase quantities. There can be no assurance that ISD
will be able to continue to obtain the orders from new customers necessary to
offset any losses of or reductions in purchases by ISD's current major
customers.

Export sales for 1997 were 79% of ISD's net revenues compared to 65% in
1996 and 1995. Geographically, sales to Europe increased to 37% of ISD's net
revenues in 1997 from 11% in 1996 and 7% in 1995; sales to South East Asia were
23% of ISD's net revenues in 1997 compared to 22% in 1996 and 35% in 1995. Japan
accounted for 19% of total net revenues in 1997 down from 31% a year earlier and
27% in 1995. North American sales were 21% of ISD's net revenues in 1997, 35% in
1996, and 35% in 1995. ISD is subject to the risk of conducting business
internationally, including foreign government regulation and general
geopolitical risks, such as political and economic instability, potential
hostilities, changes in diplomatic and trade relationships, unexpected changes
in, or imposition of, U.S. or foreign regulatory requirements, tariffs, import
and export restrictions and other barriers and restrictions, potentially adverse
tax consequences, the burdens of complying with a variety of foreign laws and
other factors beyond ISD's control. As is common in the semiconductor industry,
certain of ISD's sales are made to distributors under agreements allowing
certain rights of return and price protection on unsold products. Accordingly,
ISD defers recognition of such sales until the distributor sells the product.

Gross Margin. Gross margin increased to 31.3% in 1997 compared to 21.9% in
1996 but remained less than the 39.0% achieved in 1995. The increase in 1997
gross margin was caused by the higher margins generated from the ISD33000 and
the CompactSPEECH products, both of which are manufactured in the smaller
geometry 0.8 micron process. Gross margin in 1997 was affected by two factors:
(i) in the fourth quarter of 1997, one of ISD's international customers went
into receivership and inventory specific to this customer was written off; and
(ii) competitive and market pressures on selling prices for some of ISD's older
product lines required inventory reserves that were also recorded in the fourth
quarter of 1997. In 1996, gross margin was primarily affected by lower than
expected production yields as well as competitive pricing pressures on older
products. The higher gross margin realized in 1995 came as a result of reduced
manufacturing costs, yield improvements and the conversion to smaller (1.2
micron from 1.5 micron) geometry processes which were accomplished in 1995 and
affected the products shipped during 1995. ISD expects to continue to experience
declines in its average selling prices, which could adversely affect gross
margins, particularly if higher yields and reduced costs are not achieved.
Additionally, ISD expects that it could experience variations in gross margins
as a result of shifts in product and customer mix.

38
<PAGE> 44

Research and Development. Research and development (R&D) expenses increased
to $15.1 million in 1997 compared to $11.8 million in 1996 and $6.6 million in
1995. R&D expenditures as a percent of net revenues were 31.4% in 1997 compared
to 28.6% in 1996 and 11.8% in 1995. This increase in R&D expenses both in
absolute dollars and as a percentage of total revenues relates to continued
investment in the development of new products and to costs associated with
bringing up new technologies and new foundries; specifically this includes $4
million of R&D expense associated with the acquisition of the CompactSPEECH
product line, explained below. ISD expects research and development expenses to
increase in absolute dollars.

On March 28, 1997, ISD acquired the CompactSPEECH speech processor line
from National Semiconductor Corporation for a cash purchase price of $5.1
million. The acquisition was accounted for using the purchase method of
accounting. A portion of the purchase price was allocated to assets acquired
based on their estimated fair value, approximately $0.1 million. In addition,
$4.0 million of the purchase price was allocated to in-process research and
development projects that had not reached technological feasibility and had no
probable alternative future uses, which ISD expensed at the date of the
acquisition as a one-time non-recurring charge. The remainder of the purchase
price, $1.0 million, was allocated to goodwill and will be amortized over five
years on a straight-line basis. See Note 3 of Notes to Financial Statements.

The in-process research and development projects for the CompactSPEECH
product line relate primarily to developing significant enhancements to the
current product offering as well as introducing advanced new products. The
incomplete projects include caller I.D. Type II, the integration of all
telephone answering functions, and the ability to interface with additional
flash memory. Given the uniqueness of the tasks and the technologies involved,
alternative future uses for these projects, apart from the objectives and
economies of the projects for which they are intended, do not exist.

ISD believes that the efforts to complete the acquired in-process research
and development projects will consist of internally staffed engineering costs
over the next one to two years. These costs are estimated to be approximately
$3.0 million to complete the research and development. There can be no assurance
that ISD will succeed in making commercially viable products from the
CompactSPEECH product line.

There can be no assurance that new products will be successfully developed
or will achieve market acceptance. The success of new product introductions is
dependent on several factors, including recognition of market requirements,
product cost, timely completion or acquisition and introduction of new product
designs, quality of new products and achievement of acceptable manufacturing
yields from ISD's subcontractor manufacturers. Because of the design complexity
of its products, ISD has experienced delays from time to time in completing
development and introduction of new products, and there can be no assurance that
ISD will not encounter such delays in the development and introduction of future
products. The failure of ISD's new product development efforts or market
acceptance of such products would have a material adverse effect on ISD's
business, financial condition and results of operations.

Selling, General and Administrative. Selling, general, and administrative
expenses (SG&A) increased in 1997 to $15.7 million from $10.2 million in 1996
and $8.7 million in 1995. SG&A expenses as a percent of net revenues grew to
32.9% in 1997 compared to 24.6% in 1996 and 15.6% in 1995. Of the additional
$5.5 million in SG&A expenses incurred in 1997 compared to 1996, approximately
24% was attributable to the addition of personnel in marketing and sales.
Further, SG&A expenses increased in 1997 as a result of approximately $3.1
million in one-time charges recorded in the fourth quarter of 1997. These
one-time charges relate to a $1.4 million addition to bad debt reserves as a
result of an international customer entering receivership in the fourth quarter
of 1997, a charge of approximately $0.8 million resulting from the write-down of
certain long term investments in the fourth quarter of 1997, and approximately
$0.9 million of costs incurred in connection with implementation of the new
information system. The remainder of the increase in 1997 was primarily due to
additional legal expenses incurred in connection with the Atmel litigation. The
growth in SG&A expenses in 1996 came from additional legal, accounting and
insurance expense incurred in the first year as a public company and legal
expenses incurred in connection with the Atmel litigation matter. ISD
anticipates that SG&A expenses will continue to increase in absolute dollars.

Other Income (Expense). Net interest and other income was $2.3 million for
1997 compared to $2.4 million for 1996 and $1.8 million in 1995. The interest
income in 1997 and 1996 relates to investment

39

earnings on funds raised from the initial public offering in February 1995 and
the follow-on offering in September 1995.

Provision for Income Taxes. As a result of ISD's net loss in 1997 and the
full utilization of carryback losses in 1996, ISD recorded no provision or
benefit for income taxes. In 1996, ISD recorded a tax benefit of $1.5 million,
reflecting the carryback of 1996 losses to prior years. ISD's effective tax rate
was 29% for 1995 and reflects the utilization of federal and state net operating
loss ("NOL") and tax credit carryforwards.

At December 31, 1997, ISD had established a valuation allowance against its
total gross deferred tax asset of $8,863,000. The valuation allowance was
established due to ISD's limited history of profitability, limitations on the
utilization of NOL carryforwards, which are restricted in use under the Internal
Revenue Code of 1986 (see Note 8 of Notes to Financial Statements) and
uncertainties regarding future operations due to the increased competition
within ISD's industry.

COMPARISON OF NINE MONTHS ENDED SEPTEMBER 27, 1997 AND OCTOBER 3, 1998

Net Revenues. During the nine months ended October 3, 1998, ISD's net
revenues were principally derived from the sale of integrated circuits for voice
recording and playback. Net revenues for the nine months ended October 3, 1998
were $37.6 million. This was a 12% increase from net revenues of $33.5 million
in the first nine months of 1997. The increase in net revenues for the first
nine months of 1998 was primarily due to the ISD33000 family of ChipCorder
products maturing into production orders as compared to the early design win
orders during the same period of 1997. The ISD33000 family of ChipCorder
products accounted for approximately 49% of net revenues for the first nine
months of 1998 compared to approximately 20% for the first nine months of 1997.
The Company's current product lines have a limited lifespan. Toward the end of a
product's life cycle, revenues generated by that product tend to decline
significantly as average selling prices decrease. At the same time, the Company
must invest heavily in product development and marketing to create more
competitive systems with more features on a single chip, to develop or acquire
needed technologies, to achieve cost reductions through economies of scale and
to develop products that satisfy customer needs in the communications market. In
the consumer market, the Company must invest in developing markets for new
products. The company does not anticipate a reversal of this trend. Accordingly,
the Company anticipates that the ISD33000 family of ChipCorder products will
encounter pricing pressures over the near term and will need to be replaced with
a new product within the next two years. The Company's next product, the ISD4000
family of products based on SuperFlash memory technology, has recently been
introduced. The success of this series of products depends upon the ability of
ISD's customers to develop new applications for these products and to introduce
their products to market successfully. The willingness of prospective customers
to design ISD's products into their products depends to a significant extent
upon the ability of ISD to price its products at a level that is cost effective
for such customers

During the nine months ended October 3, 1998, sales to ISD's top ten
customers accounted for 76% of net revenues compared to 76% in the nine months
ended September 27, 1997. In the nine months ended October 3, 1998, the
Company's top five customers were Motorola, Matsushita, Siemens, Marubun and V-
Tech. These customers accounted for 30%, 11%, 9%, 7% and 6% of net revenues,
respectively, for the first nine months of 1998. The loss of, or significant
reduction in purchases by, a current major customer would have a material
adverse effect on ISD's financial condition and results of operations if the
Company were unable to obtain the orders from new or existing customers to
offset such losses or reductions.

For the first nine months of 1998, net revenues by market segment were 77%
in the communication market, 14% in the consumer market, and 9% in the
industrial market compared to 78% in the communications market, about 15% in the
consumer market, and 5% in the industrial market for the first nine months of
1997. Sales in the automotive market are included in industrial. The Company's
communications customers represent products, such as telephone answering
machines, cellular phones, cordless phones, personal handy phones and pagers.
The failure of new applications or markets to develop, or the failure of
existing markets, particularly the communications market, to continue to be
receptive to the Company's products or to offset reduced revenues from the
consumer market, could have a material adverse effect on the Company's business,
financial condition and results of operations.

40
<PAGE> 46

International sales were 83% of net revenues in the first nine months of
1998 compared to 80% in the first nine months of 1997. Sales to Europe accounted
for 47% of net revenues in the first nine months of 1998, up from 33% in the
same period in 1997. Sales to Japan were 12% of net revenues in the first nine
months of 1998, down from 24% in the first nine months of 1997, and sales to
South East Asia were 26% in the first nine months of 1998, up from 20% in the
first nine months of 1997. North American sales were 15% in the first nine
months of 1998, down from 23% for the same period in 1997. ISD is subject to the
risk of conducting business internationally, including foreign government
regulation and general geopolitical risks, such as political and economic
instability, potential hostilities, changes in diplomatic and trade
relationships, unexpected changes in, or imposition of, U.S. or foreign
regulatory requirements, tariffs, import and export restrictions and other
barriers and restrictions, potentially adverse tax consequences, the burdens of
complying with a variety of foreign laws and other factors beyond the ISD's
control. As is common in the semiconductor industry, certain of ISD's sales are
made to distributors under agreements allowing certain rights of return and
price protection on unsold products. Accordingly, ISD defers recognition of such
sales until the distributor sells the product.

Gross Margin. ISD's gross margin for the first nine months of 1998 was
$15.6 million or 41.5%, compared to the gross margin for the first nine months
of 1997 which was $11.8 million or 35.2%. This improvement in gross margin of
6.3% in 1998 compared to 1997 reflects the result of several factors: strict
cost control (approximately 2.0%); higher manufacturing yields (approximately
1.7%); improved product pricing (approximately 1.5%); and more efficient
utilization of facilities and positive absorption of overhead (approximately
1.1%).

ISD could experience difficulty as a result of converting to offshore
manufacturing and could experience fluctuations in manufacturing yields, either
or both of which could adversely affect gross margins, particularly if higher
yields, efficiency, and quality, and reduced costs are not achieved.
Additionally, ISD could experience variations in gross margins as a result of
declines in its average selling prices or shifts in product and customer mix.

Research and Development. Research and development expenses were $9.0
million, or 23.9% of net revenues, in the first nine months of 1998, compared to
$7.9 million, or 23.6% of net revenues in the same period of 1997, excluding
in-process research and development expenses related to the CompactSPEECH
acquisitions. Research and development expenses could increase as a result of
ISD's technology and new product activity associated with its recent technology
announcements. However, there can be no assurance that new products will be
successfully developed or achieve market acceptance, that yield problems on new
or existing products utilizing new foundry processes will not arise in the
future, or that product yields can be improved with respect to new or existing
products.

Selling, General and Administrative Expenses. Selling, general and
administrative expenses were $9.7 million, or 25.7% of net revenues, in the
first nine months of 1998, compared to $8.6 million, or 25.6% of net revenues in
the first nine months of 1997. Selling, general and administrative expenses
could increase as a result of sales and marketing activities, or legal expenses
incurred in connection with the Atmel litigation.

Interest and Other Income, Net. Interest and other income was $1.7 million
for the first nine months of 1998 compared to $1.7 million for the first nine
months of 1997. Interest income relates to investment earnings from the proceeds
of ISD's public offerings of common stock.

Provision for Income Taxes. Because of the loss incurred in the first nine
months of 1997 and 1998, ISD has made no provisions for income taxes.

LIQUIDITY AND CAPITAL RESOURCES

In February 1995, ISD received net proceeds of approximately $23 million in
its initial public offering and, in September 1995, ISD received net proceeds of
approximately $44 million in a follow-on public common stock offering. ISD has a
line of credit with a commercial bank under which ISD may borrow up to $15
million based on eligible assets; the term of the credit line runs through June
30, 1999. At October 3, 1998, ISD had no borrowings outstanding under this line
of credit, but the credit line is being used to guarantee certain letters of
credit generated by ISD. The line of credit does not restrict ISD from paying
cash dividends on its capital stock and the only financial covenant is to
maintain a minimum of pledged investments

41
<PAGE> 47

of $17.7 million in ISD's liquidity management account with the bank. ISD is
currently in compliance with this financial covenant under the line of credit
agreement.

ISD's operating activities used net cash of $1.2 million in 1997; used net
cash of $11.2 million in 1996; and provided $4.6 million 1995. Net cash used for
operations in 1997 and 1996 was primarily the result of ISD's net loss for both
years. In 1995 the cash provided by operations was primarily the result of ISD's
net income in 1995. Cash used by investing activities was $10.5 million in 1997
compared to $14.2 million provided in 1996 and $51.2 million used in 1995. From
1995 through 1997, investing activities consisted principally of the purchase
and maturity of investments. Cash used for financing activities was $0.2 million
in 1997 and $10.3 million in 1996. Financing activities in 1996 primarily
consisted of the repurchase of common stock. Cash provided by financing
activities was $68.3 million in 1995, primarily resulting from the sale of
common and preferred stock.

ISD's operating activities used net cash of $8.0 million in the first three
quarters of 1998, due to ISD's net loss and to an increase in inventory of $4.0
million compared to the end of the previous year. Capital purchases were $2.4
million for the first three quarters of 1998. ISD has entered into a new
operating lease agreement of $1.0 million of which $0.9 million is available
over the remainder of 1998. The Company's investment activity used cash of $3.0
million relating to the equity investment in Conversa.

At December 31, 1997, ISD had cash, cash equivalents, and short-term
investments of $39.8 million and working capital of $44.4 million. At October 3,
1998, ISD had cash, cash equivalents and short-term investments of $24.5
million, and working capital of $39 million. ISD believes its existing cash,
cash equivalents, and short-term investments and its available line of credit
and current equipment lease lines will satisfy ISD's projected working capital
and capital expenditure requirements for at least the next 12 months.

YEAR 2000 ISSUES

ISD has a well defined internal plan which identifies, eliminates, and
verifies that ISD's software and hardware applications are compliant with the
Year 2000 ("Y2K"). ISD's major systems are 100% compliant and certified. ISD
certifies that Y2K issues do not affect its products, which are used for voice
record and playback. The Company has a Y2K team with a major ongoing program
related to the assessment of its interfaces with customers, suppliers, and other
business associations. ISD's Y2K team has initiated formal communications with
each of its significant customers, suppliers and other business associations to
determine the extent to which ISD is vulnerable to any failure of those third
parties to remediate their own Y2K issues. ISD is requesting that third party
vendors represent their products and services to be Y2K compliant and that they
have a program to test for Y2K compliance. However, the response of those third
parties is beyond ISD's control. To the extent that ISD does not receive
adequate responses by December 31, 1998, ISD is prepared to develop contingency
plans, with completion of these plans scheduled for no later than March 31,
1999. At this time, ISD cannot estimate the additional cost, if any, that might
develop from such contingency plans. ISD does not expect the costs to complete
Y2K compliance to be material. Breakdowns in ISD's computer systems and
applications, such as its manufacturing application software, its bar-coding
systems and the computer chips embedded in its plant equipment, as well as other
Y2K-related problems such as disruptions in the delivery of materials, power,
heat or water to ISD's facilities, could prevent ISD from being able to
manufacture and ship its products. ISD plans to replace, upgrade or otherwise
work around any of its date driven systems that are not Y2K compliant. ISD's Y2K
team intends to have compliance solutions or work-arounds planned by December
31, 1998 and intends to complete compliance testing by June 30, 1999. If ISD
fails to correct a material Y2K problem, its normal business activities and
operations could be interrupted. Such interruptions could materially adversely
affect ISD's business, financial condition and results of operations.

OTHER FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS

This section on "Other Factors That May Affect Future Operating Results"
includes forward-looking statements that reflect ISD's current views with
respect to future matters such as factors that can affect ISD's operating
results, foundry capacity, litigation, manufacturing yields, the markets for
ISD's products and protection of intellectual property. This section also
contains cautionary statements that identify important factors, including
certain risks and uncertainties, that could cause actual results or outcomes to
differ materially from those in the forward-looking statements in this section
and elsewhere in this Report.

Dependence on Foundries. All of ISD's products are manufactured by four
independent foundries. ISD's primary supplier is Samsung Electronics Co., Ltd.
("Samsung") in Korea, which supplied wafers comprising about 78% of ISD's 1997
net revenues. Approximately 20% of ISD's 1997 net revenues were supplied by
wafers produced at Tower Semiconductor ("Tower") in Israel. Rohm Semiconductor
Co., Ltd. ("Rohm") in Japan accounted for about 1% of 1997 net revenues as did
Sanyo Electronic Co., Ltd. ("Sanyo") in Japan. ISD depends on these foundries to
allocate to ISD a portion of their foundry capacity sufficient to meet ISD's
needs, to produce products of acceptable quality with acceptable manufacturing
yields and to deliver products to ISD on time. On occasion, ISD has experienced
difficulties in each of these areas, and ISD is likely to experience such
difficulties in the future. In order to obtain this capacity or other capacity,
ISD may be obligated to pay nonrecurring engineering fees or make certain other
payments to any one of its foundries. There can be no assurance that ISD will
receive its desired allocation of product at these foundries or that additional
needed foundry capacity will be qualified. The loss of Samsung or Tower as a
supplier, the inability of ISD or Samsung to obtain a license from Atmel
Corporation ("Atmel") should that become necessary, the inability of ISD to
maintain or expand foundry capacity from its current suppliers or to qualify
other wafer manufacturers so ISD can obtain additional foundry capacity, any
inability to obtain timely and adequate deliveries from ISD's current or future
suppliers or any other circumstance that would require ISD to seek alternative
sources of supply could constrain, interrupt or delay shipments of ISD's
products and have a material adverse effect on ISD's business and results of
operations. ISD's reliance on third party manufacturers also involves a number
of additional risks, including but not limited to reduced control over delivery
schedules, quality assurance and costs. See "Information Concerning ISD's
Business -- Manufacturing."

Intellectual Property Litigation. The semiconductor industry is
characterized by vigorous protection and pursuit of intellectual property rights
or positions, which have resulted in significant and often protracted and
expensive litigation. On June 15, 1995, Atmel filed a complaint in the United
States District Court for the Northern District of California which alleges
causes of action against ISD for patent infringement, trade secret
misappropriation, breach of written contract, breach of contract
implied-in-fact, unjust enrichment and declaratory relief. Atmel, in addition to
damages and injunctive relief, is seeking a declaration from the Court that
Atmel is a co-owner of ISD's ChipCorder products. ISD believes the causes of
action in the complaint to be without merit and has had its general counsel file
an answer denying any wrongful conduct and asserting counterclaims for damage
caused ISD by Atmel's termination of the fabrication arrangement between the
parties. The Court has bifurcated the issues related to liability and damages.
On February 27, 1998, the Court issued a decision regarding the patent claims.
ISD believes that this decision is at least in part favorable to ISD. On April
14, 1998, the Court issued a decision invalidating one of the asserted patents.
Atmel has filed a Notice of Appeal of that decision. On November 5, 1998, the
Court granted summary judgment of non-infringement in favor of ISD on the two
remaining patents asserted. While ISD does not believe the ultimate resolution
of this matter will have a material impact on its business or financial
position, it may have a material adverse impact on the results of operations in
the period in which it is resolved. See "Information Concerning ISD's
Business -- Legal Proceedings."

number of die produced on each wafer. Problems with future transitions of this
type could cause disruptions in the manufacturing flow and reduce manufacturing
yields. The inability of ISD to achieve improved yields could prevent revenue
growth and margin improvements from existing capacity. There can be no assurance
that ISD's foundries will achieve or maintain acceptable manufacturing yields in
the future or that sudden declines in yields will not again occur. Failures to
improve, or fluctuations in, manufacturing yields, particularly at times when
ISD is experiencing severe pricing pressures from its customers or its
competitors, would have a material adverse effect on ISD's business and results
of operations. See "Information Concerning ISD's Business -- Manufacturing."

Dependence Upon Emerging Markets. ISD's success depends to a significant
extent upon the development of new applications for voice recording and playback
in the communications, consumer and industrial markets. In addition, product
life cycles in the communication and consumer markets are typically short. As a
result, customers must design ISD's products into their products as each new
generation is developed. Furthermore, ISD expects that it may sell many of its
new products, including products with longer recording durations now under
development, to customers that are developing new product applications and
markets. Accordingly, the success of ISD will depend upon the success of its
customers in developing such applications and markets. There can be no assurance
that new applications or markets will develop as expected by ISD or that
prospective customers developing products for any such markets will design ISD's
products into their products and successfully introduce such products. The
failure of new applications or markets to develop or the failure of new markets
to be receptive to ISD's products could have a material adverse effect on ISD's
business, financial condition and results of operations.

The willingness of prospective customers to design ISD's products into
their products depends to a significant extent upon the ability of ISD to price
its products at a level that is cost effective for such customers. The markets
for most of the potential applications for ISD's products, particularly the
consumer market, are characterized by intense price competition. As the markets
for ISD's products develop and competition increases, ISD anticipates that its
average selling prices on these products will continue to decline, particularly
as product technology matures and if per order unit volumes for such products
increase. These and other downward pressures on ISD's average selling prices
will require ISD to seek sales in emerging markets where average selling prices
may be higher and to produce its products at lower cost if it is to avoid
significant degradation in its gross margins. To the extent that ISD fails to
facilitate its customers' opening of new markets, experiences yield or other
production problems or shortages in supply that increase its manufacturing
costs, or fails to reduce its manufacturing costs, it would have a material
adverse effect on ISD's business, financial condition and results of operations.

Protection of Proprietary Rights. ISD relies on a combination of patents,
mask work protection, trademarks, copyright and trade secret laws,
confidentiality procedures and licensing arrangements to protect its
intellectual property rights. There can be no assurance that any patents held by
ISD will not be challenged and invalidated, that patents will issue from any of
ISD's pending applications or that any claims allowed from existing or pending
patents will be of sufficient scope or strength or be issued in all countries
where ISD's products can be sold to provide meaningful protection or any
commercial advantage to ISD. Competitors of ISD also may be able to design
around ISD's patents. In addition, parties might have or obtain patents or other
exclusive proprietary rights that would potentially limit the number of possible
customers for ISD's products for certain applications. Any such limitations in
ISD's potential markets could have a material adverse effect on ISD's business,
financial condition and results of operations. Finally, the laws of certain
foreign countries in which ISD's products are or may be developed, manufactured
or sold, including various countries in Asia, may not protect ISD's intellectual
property rights to the same extent as do the laws of the United States and thus
make the possibility of piracy of ISD's products more likely.

Potential Fluctuations in Operating Results. ISD's operating results are
subject to quarterly and annual fluctuations due to a variety of factors,
including availability of foundry capacity and raw materials, fluctuations in
manufacturing yields, competitive pricing pressures, the timing of significant
orders, changes in shipment schedules, changes in the mix of products sold,
changes in the mix of customers, availability and cost of products from ISD's
suppliers, the timing of new product announcements and introductions by ISD and
its competitors, the cyclical nature of the semiconductor industry and certain
markets addressed by ISD's

44
<PAGE> 50

products, the gain or loss of significant customers, increased research and
development expenses associated with new product introductions or enhancements,
market acceptance of new or enhanced versions of ISD's products, changes in the
channels through which ISD's products are distributed, and economic conditions
generally or in various geographic areas. These factors are difficult to
forecast, and these or other factors can materially affect ISD's quarterly or
annual operating results. ISD's operating results will also fluctuate as a
result of seasonal factors. Demand for cell phones and other products that
incorporate ISD's products generally is strongest in the third and fourth
quarters of each year. In addition, ISD expects to continue to increase its
operating expenses for personnel and new product development. If ISD does not
achieve increased levels of revenues commensurate with these increased levels of
operating expenses, ISD's operating results will be materially adversely
affected.

For a discussion of other factors that may affect future operating results,
see "Information Concerning ISD's Business -- Marketing, Sales and
Distribution," "-- Manufacturing," "-- Research and Development,"
"-- Competition" and "-- Employees."

All of the above factors are difficult to forecast, and these or other
factors can materially affect ISD's quarterly or annual operating results. No
assurance can be given that ISD will be able to achieve or maintain
profitability on a quarterly or annual basis in the future. Due to all of the
foregoing factors, it is possible that in some future quarter ISD's operating
results will be below the expectations of stock market analysts and investors.
In such event, the price of ISD's Common Stock would likely be materially
adversely affected.

INFORMATION CONCERNING ISD'S BUSINESS

ISD designs, develops, and markets semiconductor voice solutions based on
analog and digital technologies and mixed signal expertise. ISD's patented
ChipCorder and CompactSPEECH technologies enable solid state voice recording and
playback applications in the communications, consumer, industrial and automotive
markets. ChipCorder products deliver single chip solutions, simple integration,
exceptional sound quality, low power consumption, battery-less voice storage,
and low cost. CompactSPEECH products deliver powerful digital speech processing,
advanced telecommunication capabilities, long recording times, cost effective
high voice quality, multi-language speech synthesis, and battery-less voice
storage. ISD was incorporated in California in December 1987. Volume production
shipments commenced in 1992 and net revenues grew every year until 1996. In
1997, net revenues grew by 16% over 1996 net revenues. In the first nine months
of 1998, net revenues grew by 12% over the first nine months of 1997.

MARKETS, APPLICATIONS AND CUSTOMERS

ISD's mission is to provide products to the communications marketplace
using its proprietary multi-level storage and related technologies. The wireless
communication and telecommunication markets continue to be a key focus for ISD.
While these industries form a large part of ISD's current business, ISD also
provides products to the consumer, industrial and automotive markets. In 1997,
79% of net revenues was derived from the communications market, and the consumer
and the industrial (including automotive) markets accounted for 12% and 9% of
net revenues, respectively. In the first nine months of 1998, 77% of net
revenues was derived from the communications market, and the consumer and the
industrial (including automotive) markets accounted for 14% and 9% of net
revenues, respectively.

Sales to ISD's top ten customers accounted for 76% of net revenues in the
first nine months of 1998 compared to 76% in 1997, 85% in 1996, and 66% in 1995.
The top five customers in the first nine months of 1998 were Motorola,
Matsushita, Siemens, Marubun (ISD's Japanese distributor), and V-Tech,
accounting for 30%, 11%, 9%, 7%, and 6% of net revenues, respectively.

Communications Market

ISD has broadened its marketing efforts in the communications market by
introducing the ISD33000 ChipCorder series, the industry's first family of
3-volt, single-chip record and playback products optimized for communication
devices including cellular and portable phones. Earlier versions of ISD's record
and playback chips are still being used in cellular phones (as an answering
machine function or as a voice memo pad) and many other products, including
pagers and traffic information systems. The ISD33000 Series is optimized for
both analog and digital cellular phones -- including Global System Mobile (GSM),
Personal Communication Service (PCS), Personal Handy Phone System (PHS),
Japanese Digital Cellular (JDC), and cordless phones that rely on 3-volt
technologies to minimize power consumption. In addition to cellular and portable
phones, the ISD33000 has also been designed into pocket recorders and telephone
applications. Along with offering true 3-volt operation, the ISD33000 product
family offers longer recording durations than previous ISD products: up to four
minutes. In April 1998, ISD expanded its communications ChipCorder product
offering with the introduction of the ISD4000 series, the industry's first and
only single chip solution with record and playback durations up to 16 minutes.

The largest single application for ISD's products in the communications
market is currently the cellular phone. A number of manufacturers, including
Benefon, Casio, Ericsson, JVC, Motorola, Philips, Pioneer, Sagem, Sanyo, Sharp,
Sony, Toshiba and Matsushita (Panasonic), have incorporated ChipCorder products
in their communications products. Motorola has designed ISD's products into its
MicroTAC Elite and StarTAC cellular phones to record incoming messages and/or
voice memos directly into the phone. Other representative applications for
ChipCorder products in the communications market include mobile radios, caller
ID devices, telephone announcement systems, personal handy phones and voice
pagers.

The second largest application for ISD's products in the communications
market is the telephone answering machine. ISD is developing single-chip
solutions with considerably longer durations that would

46
<PAGE> 52

address both customers' outgoing and incoming message requirements and
accelerate the migration to all integrated circuit-based TADs (i.e., those that
eliminate tape mechanisms).

The acquisition of the CompactSPEECH product line in April 1997 brought
advanced, high quality digital speech processing technology and telephony
features such as full duplex speaker phone and call ID capabilities to ISD's
product portfolio. CompactSPEECH products have also expanded ISD's record and
playback durations to up to one hour. The addition of the CompactSPEECH product
line has expanded ISD's large base of customers to include several new ones such
as Philips, Siemens, and VTech.

Consumer Market

ISD's marketing efforts for its first generation, short duration products
were directed toward the consumer market. ISD believes that the high voice
quality, ease of use, non-volatility and low cost of its products combined with
the short design-in cycle typical of the consumer market have allowed ISD's
customers to bring their products to market rapidly and economically. ISD's
customers in the consumer market typically integrate a voice recording and
playback function to create a new product concept or to differentiate an
existing product with additional features or functionality. Prior to the
introduction of ChipCorder products, voice functions were almost all
accomplished by read only memory ("ROM") devices, which typically have very low
speech quality and can be used only to play back pre-recorded messages.
Representative applications for ChipCorder products in the consumer market
include interactive books for children, keepsakes, novelties, pocket recorders,
cameras, recordable greeting cards, recordable photograph frames, toys and
games.

During 1997, ISD introduced the ISD1500 series, a family of low-cost single
chip record and play solutions for the price sensitive consumer market. This
product family delivers high quality single message functionality with added
features such as sound warping and user selectable duration.

Industrial Market

Industrial applications for ISD's products are largely oriented toward
voice prompting (i.e., providing a voice interface between the user and the
product) and include applications for alerting, educating, guiding, informing,
prompting and warning. Prior to ChipCorder technology, this market opportunity
had not been well developed because of the complexity of existing voice
solutions, poor voice quality and the high minimum purchase requirements imposed
by manufacturers of ROM-based single-chip solutions. ISD's products offer OEM
customers in the industrial market the ability to differentiate their products
by providing improved functionality and voice interface. ChipCorder products
have the advantages of being easy to record and re-record and of maintaining the
recording in the event of power loss or battery replacement. The industrial
market is characterized by low to moderate production volumes. Representative
applications for ChipCorder products in the industrial market include
announcement/annunciator systems, building security systems, instrumentation,
alarms and point of sale displays.

PRODUCTS

ChipCorder Products

ISD currently offers seven product families incorporating its ChipCorder
technology. These products are available in die or packaged form and range in
retail list price from less than $0.75 to approximately $11.00 per unit.

ISD's original product family, the ISD1000A series, was the industry's
first single-chip recording and playback device. This product won numerous trade
awards, including the 1991 Electronic Design News Magazine "Innovation of the
Year" award and the Electronic Products Magazine "1991 Product of the Year"
award. The ISD33000 series offered substantially longer voice recording and
playback durations up to four minutes. This product family has enabled the
development of a wide variety of product applications, particularly
communications and industrial applications. The ISD4000 series furthers
recording durations on a single chip to 16 minutes.

Most of ISD's ChipCorder products include an on-chip oscillator, microphone
preamplifier, automatic gain control, antialiasing filter, smoothing filter and
speaker amplifier. A complete record and playback system can be configured with
the addition of a microphone, a speaker, a power source and a few resistors and
capacitors. ISD's products are microprocessor compatible, and provide users with
complex messaging and addressing capability.

CompactSPEECH Products

The CompactSPEECH product series provides high quality speech processing,
long recording times, caller ID, full duplex speaker phone functionality and
multi-language speech synthesis. CompactSPEECH products were the first to
provide a digital telephone answering solution with non-volatile memory support.
CompactSPEECH products are available in various packaging options and retail
between $3.20 and $7.00, depending on volume and packaging options.

MARKETING, SALES AND DISTRIBUTION

ISD markets and distributes its products through a direct sales and
marketing organization and a worldwide network of sales representatives and
distributors. Major OEM accounts are served directly by ISD's salespeople and
support staff, which includes applications engineers and customer service
personnel. ISD manages its direct sales force from its headquarters in San Jose,
California, and has offices located in Herzliya, Israel and the states of New
York and Texas.

In North America, ISD has 19 sales representatives. In addition, ISD has a
non-exclusive distributor that sells ISD's products directly to many customers
throughout North America, a non-exclusive Canadian distributor and a
non-exclusive distributor in South America. None of these distributors is
subject to any minimum purchase requirements and any of them can cease promotion
of ISD's products at any time. Select ISD products are also sold through Radio
Shack and Digi-Key Corporation.

Internationally, ISD has 27 distributors located in Australia, China, Hong
Kong, Israel, Japan, Korea, South Africa, Taiwan, Singapore, and every major
country in Europe. ISD also has sales representatives in England, France,
Germany, and Italy. ISD relies on its distributors for local product promotion
and customer support, including identification and development of customers,
applications support, and media promotion, such as public relations and
advertising activities. ISD's agreements with its international distributors and
representatives are renewable on an annual basis, but can be terminated or
discontinued at will.

Export sales (sales outside North America) constituted approximately 65%,
65%, 79% and 85% of ISD's net revenues for 1995, 1996, 1997 and the first nine
months of 1998, respectively. Due to its reliance on export sales, ISD is
subject to the risks of conducting business internationally, including foreign
government regulation and general geopolitical risks such as political and
economic instability, potential hostilities and changes in diplomatic and trade
relationships. In addition, the laws of certain foreign countries in which ISD's
products are or may be sold, including various countries in Asia, may not
protect ISD's intellectual property rights to the same extent as do the laws of
the United States and thus make the possibility of piracy of ISD's products more
likely. Sales of ISD's products may also be materially adversely affected by
factors such as unexpected changes in, or imposition of, U.S. or foreign
regulatory requirements, tariffs, import and export restrictions and other
barriers and restrictions, longer payment cycles, greater difficulty in accounts
receivable collection, potentially adverse tax consequences, the burdens of
complying with a variety of foreign laws and other factors beyond ISD's control.
Because ISD's foreign sales are denominated in U.S. dollars, ISD's products
become less price competitive in countries with currencies declining in value
against the dollar. There can be no assurance that these factors will not have a
material adverse effect on ISD's business, financial condition or results of
operations in the future or require ISD to modify its current business
practices.

A limited number of customers historically has accounted for a substantial
portion of ISD's net revenues. In 1995, 1996, 1997 and the first nine months of
1998, sales to ISD's top ten customers, including those discussed below,
accounted for approximately 66%, 85%, 76% and 76%, respectively, of ISD's net
revenues. Sales to Marubun, ISD's Japanese distributor, and Motorola accounted
for 16% and 13%, respectively, of ISD's net revenues in 1995, 23% and 29%,
respectively, in 1996, 19% and 17%, respectively, in 1997 and 7%

48
<PAGE> 54

and 30%, respectively, in the first nine months of 1998. Sales to Matsushita and
Philips accounted for 13% and 11% of net revenues, respectively, in 1997 and 11%
and 2% of net revenues, respectively, in the first nine months of 1998. ISD
expects that sales of its products to a limited number of customers will
continue to account for a substantial portion of its revenues for the
foreseeable future. ISD has also experienced changes in the composition of its
customer base from year to year and expects this pattern to continue. The loss
of, or significant reduction in purchases by, current major customers, would
have a material adverse effect on ISD's business, financial condition and
results. ISD's customers typically do not contract for minimum purchase
quantities. There can be no assurance that ISD will be able to continue to
obtain the orders from new customers necessary to offset losses of or reductions
in purchases by ISD's current major customers.

ISD's sales are also subject to seasonal factors, such as the demand for
cellular phones and other products that incorporate ISD's products, which is
generally strongest in the third and fourth quarters of each year.

CUSTOMER APPLICATIONS ENGINEERING AND TECHNICAL SUPPORT

To promote acceptance of the ChipCorder and CompactSPEECH products, ISD
provides applications engineering and technical support to its customers. ISD
has implemented an extensive support effort that begins with its sales force,
and extends through the manufacturing and delivery of its products. ISD offers
product design assistance to help customers with limited electronics expertise
create innovative new products. ISD has applications engineering staff located
at its headquarters in San Jose, California, and at its office in Austin, Texas.
In addition to publishing application documentation and other customer support
documents, ISD's applications engineering staff works with customers directly to
facilitate the design-in of ISD's products. ISD's independent sales
representatives supplement the applications and technical support functions by
providing such services directly to customers. ISD works closely with the
independent sales representative organizations to enhance their ability to
provide applications and technical support directly.

Although development systems are not required with ChipCorder or
CompactSPEECH devices, ISD offers several evaluation tools and
development/programming systems. These tools allow users to record and play back
messages, create, edit and mass program ISD devices with accurate message
location, and develop or test the products' application environment by using a
PC as the host system to interact with the product.

TECHNOLOGY

ISD's technology differentiation lies in its patented technique for storing
multilevel signals which is used in the design of all ChipCorder products. In
conventional digital data storage, each memory cell stores one of two "bits" of
information, either a "1" or a "0," or, in terms of voltage levels, either an
"on" or an "off." Using ISD's multilevel storage technology, each ChipCorder
memory cell can store one of more than 250 voltage levels, approximately the
equivalent of eight bits of storage, without any conversion to digital data.
Thus, for a given quality of voice reproduction, ChipCorder products require
one-eighth the silicon storage space of conventional digital storage techniques
and typically provide a cost advantage over such digital storage technologies in
delivering high-quality voice solutions. Because ISD's ChipCorder technology
enables the direct storage of voice and audio signals without analog-to-digital
conversion, the amount of external circuitry required can also be reduced.
ChipCorder products need only a microphone, a speaker, power source and a few
resistors and capacitors to implement a complete solid-state, tapeless,
record/playback function. Since ChipCorder products use nonvolatile memory, they
do not require continuous power or battery backup to preserve the recorded
message. Overall power consumption, therefore, is reduced, making ISD's products
ideal for handheld, portable, battery-powered applications.

ISD achieves multilevel storage of analog signals through architectural,
algorithmic and circuit design techniques without the need for special
manufacturing processes. The ISD1000 series product was designed using CMOS
EEPROM processes, with 128,000 storage cells. ISD's technology can migrate and
scale within industry production technology and standards, and thus can take
advantage of improvements in digital memory processing. Each generation of new
products, from the original ISD1000 series, through the ISD4000 series, to the
new products under development today, benefits from cell area reductions driven
by memory technology advances thereby giving ISD significant advantages in
density as its products migrate to smaller production geometries. ISD selects
its wafer foundries according to its assessment of their ability to make
continually improving process densities available to ISD.

49
<PAGE> 55

ISD's technology is compatible with floating gate processes that use
Fowler-Nordheim tunneling for both erasing and programming the storage cell, as
used in most digital EEPROM and some "flash" processes. No special process steps
or cell structures are required. ISD's technology is transferable from one wafer
source to another allowing ISD to provide alternate wafer sources and position
ISD to negotiate for more attractive wafer or die pricing, wafer volume and
future technology improvements.

MANUFACTURING

Foundries. ISD subcontracts with independent silicon foundries to fabricate
the wafers for all of its products. This approach enables ISD to concentrate its
resources on the design, development and marketing areas, where ISD believes it
has the greatest competitive advantage, and eliminates the high cost of owning
and operating a semiconductor wafer fabrication facility.

All of ISD's products are manufactured by four independent foundries. ISD
has supply arrangements with each of its current foundries, and ISD and its
foundries agree on production schedules based on purchase orders and forecasts
for the next six to twelve months. ISD's primary supplier is Samsung, which
supplied wafers comprising about 78% of ISD's 1997 net revenues. Approximately
20% of ISD's 1997 net revenues were supplied by wafers produced at Tower in
Israel. Rohm in Japan accounted for about 1% of 1997 net revenues as did Sanyo
in Japan. In January 1995, Atmel notified ISD and Samsung of certain claims and
demanded that ISD and Samsung either negotiate licenses with Atmel or cease
manufacturing ISD's products at Samsung, and, in June 1995, Atmel filed suit
against ISD. See "-- Legal Proceedings."

ISD is dependent on these foundries to allocate to ISD a portion of their
foundry capacity sufficient to meet ISD's needs, to produce products of
acceptable quality and with acceptable manufacturing yields and to deliver
products to ISD on time. On occasion, ISD has experienced difficulties in each
of these areas, and ISD is likely to experience such difficulties in the future.
In order to obtain this capacity or other capacity, ISD may be obligated to pay
nonrecurring engineering fees or make certain other payments to any one of its
foundries. ISD has qualified wafer fabrication facilities at Samsung, Tower,
Winbond and Rohm. However, there can be no assurance that ISD will continue to
receive its desired requirements of product at these foundries. The loss of
Samsung or Tower as a supplier, the inability of ISD or Samsung to obtain a
license from Atmel should that prove to be necessary, the inability of ISD to
maintain or expand foundry capacity from its current suppliers or to qualify
other wafer manufacturers so ISD can obtain additional foundry capacity, any
inability to obtain timely and adequate deliveries from ISD's current or future
suppliers or any other circumstance that would require ISD to seek alternative
sources of supply could constrain, interrupt or delay shipments of ISD's
products and have a material adverse effect on ISD's business, financial
condition and results of operations.

ISD's reliance on third party manufacturers involves a number of risks,
including but not limited to reduced control over delivery schedules, quality
assurance and costs. In addition, as a result of ISD's dependence on foreign
subcontractors, ISD is subject to the risks of conducting business
internationally, including foreign government regulation and general
geopolitical risks, such as political and economic instability, potential
hostilities, changes in diplomatic and trade relationships, unexpected changes
in, or imposition of, U.S. or foreign regulatory requirements, tariffs, import
and export restrictions and other barriers and restrictions, potentially adverse
tax consequences, the burdens of complying with a variety of foreign laws and
other factors beyond ISD's control. ISD's agreements with its offshore wafer
fabrication and assembly facilities provide for pricing and payment in U.S.
dollars.

ChipCorder and CompactSPEECH products are designed using the process
specifications of ISD's foundries. Currently, the foundries use CMOS process
technology with 1.2, 0.8 and 0.6 micron feature sizes. To reduce manufacturing
costs, ISD continuously evaluates the benefits of migrating particular products
to smaller geometry process technologies. In 1997, wafers produced on a 0.8
micron process accounted for almost half of ISD's net revenues. Migration to
smaller geometries is essential if ISD is to remain cost competitive, and
operating results could be materially adversely affected if these transitions
are substantially delayed or inefficiently implemented. ISD has experienced
delays in these migrations, and there can be no assurance that further delays
will not occur.

<PAGE> 56

Manufacturing Yields. The fabrication of integrated circuits is a highly
complex and precise process, requiring production in a highly controlled, clean
environment. As a result, ISD has experienced problems in achieving an
acceptable wafer manufacturing yield, which is the number of good die
(semiconductor products) that results from each manufactured wafer as a
proportion of the total potential die on the wafer. As is typical in the
semiconductor industry, ISD purchases its products from its suppliers on either
a wafer or die basis. Because the capacity for production of wafers is limited,
low yields decrease the total number of products available for delivery to ISD.
Semiconductor manufacturing yield is a function both of design technology, which
is developed by ISD, and process technology, which is typically proprietary to
the foundry. The design is created from the design rules depicting the process
technology. Since low yields may result from either design or process technology
failures, yield problems may not be effectively determined or improved until an
actual product exists that can be analyzed and tested to recognize process
sensitivities in relation to the design rules that are used. As a result, yield
problems may not be identified until well into the production process and
require cooperation by and communication between ISD and the foundry for
resolution. ISD is particularly susceptible to yield problems because it is not
in direct control of the independent offshore foundries that manufacture its
products, which increases the effort and time required to identify, communicate
and resolve manufacturing yield problems. In addition, as ISD qualifies
additional foundries, ISD must design its products using the process technology
and design rules of each of these foundries.

In the past, ISD has experienced yield problems on its ISD1400 series as it
was converted to the 1.2 micron process and on its ISD2500 series as it was
converted to the 0.8 micron process. The ISD33000 experienced a yield problem in
the third and fourth quarters of 1997. The current levels are variable and ISD
continues to take actions to improve the yields. The inability of ISD to achieve
improved yields could prevent revenue growth and margin improvement from
existing capacity. There can be no assurance that ISD's foundries will achieve
or maintain acceptable manufacturing yields in the future or that sudden
declines in yields will not again occur. Failure to improve, or fluctuations in,
manufacturing yields, particularly at times when ISD is experiencing severe
pricing pressures from its customers or its competitors, would have a material
adverse effect on ISD's business, financial condition and results of operations.

Testing and Assembly. Wafers that have been tested and accepted by ISD are
cut into die and either sold in that form or assembled into packages by
subcontractors located in either Korea or the Philippines. ISD qualifies and
monitors assembly contractors using procedures similar in scope to those used
for wafer procurement. For products sold in die form, ISD also employs several
"die preparation" subcontractors that are located in Taiwan, the Philippines,
China, and Thailand. ISD's die preparation and assembly subcontractors provide
fixed cost per-unit pricing, as is common in the semiconductor industry.

In the third quarter of 1998, the Company consolidated a substantial
portion of its wafer sort and final test manufacturing operation to AMKOR, the
Company's assembly and test subcontractor in the Philippines. This consolidation
enables ISD to ship wafers directly from its wafer foundries to AMKOR for
turnkey manufacturing and direct shipment of finished product directly to the
customer.

Because ISD's products are manufactured and assembled by independent
subcontractors, ISD is subject to the risks of shortages, and increases in the
cost, of raw materials used in the manufacture or assembly of ISD's products.
Shortages of raw materials or disruptions in the provision of services by ISD's
manufacturing or assembly houses or other circumstances that would require ISD
to seek alternative sources of supply or assembly could lead to constraints,
interruptions or delays in timely delivery of ISD's products. Such constraints,
interruptions or delays or any other problem resulting from the risks described
above might result in the loss of customers, limitations or reductions in ISD's
revenues or other material adverse effects on ISD's business, financial
condition and results of operations.

Quality Assurance. The communications industry demands high quality and
reliability. ISD seeks to build product reliability into each circuit from the
beginning stages of design, through specific design and layout reliability
guidelines. Also, to maximize quality, reliability and yield relationships, ISD
participates in quality and reliability monitoring through each aspect of the
production cycle by reviewing electrical and inspection data from its wafer
foundry and assembly subcontractors. ISD monitors wafer foundry production for
consistent overall quality, reliability and yield levels. As part of its total
quality program, ISD completed its

51
<PAGE> 57

ISO 9001 certification in October of 1996 and the 1997 surveillance audit with
no deviations. All of ISD's wafer foundries and package assembly facilities are
also ISO 9000 certified.

RESEARCH AND DEVELOPMENT

The markets for ISD's products are characterized by rapidly changing
technology and evolving industry standards. ISD's operating results will depend
to a significant extent on its ability to introduce commercially attractive and
competitively priced new products on a timely basis and to reduce production
costs of existing products. ISD believes that continued significant expenditures
for research and development will be required in the future as ISD develops more
products with improved features. During 1997, ISD introduced the short duration
ISD1500, an innovative, low cost circuit topology manufactured at Rohm in Japan;
and demonstrated the eight minute record and playback capability utilizing a
flash-based technology built at Winbond. In addition, in April 1997, ISD
established a design center in Israel to support the CompactSPEECH product line.
This design center is also responsible for the enhancement of the existing
products as well as development of ISD's next generation of digital signal
processing ("DSP") products.

In 1998, the Company continued its efforts to being to market longer
duration chips which was substantiated by several announcements, including the
availability of samples of the ISD4000 family, the industry's only single chip
solution with record and playback durations up to 16 minutes. The ISD4000 family
of record and playback chips is based on SuperFlash memory technology
manufactured by Winbond.

There can be no assurance that these products will be successfully
developed or will achieve market acceptance. The failure of any of these
products to be introduced successfully or to achieve market acceptance could
have a material adverse effect on ISD's business, financial condition and
results of operations. The success of new product introductions is dependent on
several factors, including recognition of market requirements, product cost,
timely completion or acquisition and introduction of new product designs,
quality of new products and achievement of acceptable manufacturing yields from
ISD's subcontractor manufacturers. Because of the design complexity of its
products, ISD has experienced delays from time to time in completing development
and introduction of new products, and there can be no assurance that ISD will
not encounter such delays in the development and introduction of future
products. There can be no assurance that ISD will successfully identify new
product opportunities and develop or acquire and bring new products to market in
a timely manner, that ISD's products will be selected for design into the
products of its targeted customers or that products or technologies developed by
others will not render ISD's products or technologies obsolete or
noncompetitive. The failure of ISD's new product development efforts or market
acceptance of such products would have a material adverse effect on ISD's
business, financial condition and results of operations.

Research and development expenses in 1995, 1996, 1997 and the first nine
months of 1998 were approximately $6.6 million, $11.8 million, $15.1 million and
$9.0 million, respectively. Fiscal 1997 research and development expenses
includes $4.0 million of in-process research and development related to ISD's
CompactSPEECH product line acquisition. As of October 3, 1998, ISD had 60
full-time and contract employees engaged in research and development.

BACKLOG

As of December 31, 1997, ISD's total backlog was $13.8 million, compared to
$6.8 million as of December 31, 1996. As of October 3, 1998, the Company's total
backlog was $11.8 million, compared to $8.8 million as of September 27, 1997.
ISD's backlog consists of customers' purchase orders that have been booked,
acknowledged by ISD and scheduled for shipment within six months.

ISD's business and, to a large extent, that of the entire semiconductor
industry, is characterized by short-term order and shipment schedules. Since
orders constituting ISD's current backlog are subject to changes in delivery
schedules or to cancellation at the option of the purchaser without significant
penalty, backlog is not

52
<PAGE> 58

necessarily an indication of future revenue. In addition, there can be no
assurance that current backlog will necessarily lead to revenues in any future
period. Cancellations of pending purchase orders or termination or reduction of
purchase orders in progress could have a material adverse effect on ISD's
business, financial condition and results of operations.

PATENTS AND LICENSES

ISD relies on a combination of patents, mask work protection, trademarks,
copyright and trade secret laws, confidentiality procedures and licensing
arrangements to protect its intellectual property rights. ISD seeks the issuance
of patents to protect inventions and technology that support ISD's multilevel
storage technology and various architectural, circuit design and other
techniques. ISD currently has 23 patents granted (including one patent that was
acquired), 20 patents pending and 4 patent applications in preparation in the
United States, and intends to seek further United States patents on its
technology. ISD's already issued U.S. patents expire between July 2008 and
October 2016. The terms of the issued U.S. patents and any U.S. patent issued in
the future are subject to ISD's making required annuity payments to the U.S.
Patent and Trademark Office three years and six months, seven years and six
months, and eleven years and six months after the respective issue dates of the
patents. ISD has also filed applications for 90 patents in Europe, Japan and
elsewhere; has two patents granted in Europe and four patents granted in Korea;
and intends to seek further foreign patents. Maintenance of the foreign
applications and patents also depends upon the timely payment of annuities in
accordance with the applicable foreign requirements. ISD has nine United States
mask work registrations, and plans to apply for additional such registrations as
necessary. There can be no assurance that any patents held by ISD will not be
challenged and invalidated, that patents will issue from any of ISD's pending
applications or that any claims allowed from existing or pending patents will be
of sufficient scope or strength or be issued in all countries where ISD's
products can be sold to provide meaningful protection or any commercial
advantage to ISD. Competitors of ISD also may be able to design around ISD's
patents. In addition, parties might have or obtain patents or other exclusive
proprietary rights that would potentially limit the number of possible customers
for ISD's products for certain applications. Any such limitations in ISD's
potential markets could have a material adverse effect on ISD's business,
financial condition and results of operations. Finally, the laws of certain
foreign countries in which ISD's products are or may be developed, manufactured
or sold, including various countries in Asia, may not protect ISD's intellectual
property rights to the same extent as do the laws of the United States and thus
make the possibility of piracy of ISD's products more likely.

ISD owns five trademarks registered in the United States; has eight
additional United States applications pending; and has eight trademark
applications pending in Israel. ISD attempts to protect its circuit designs,
software, trade secrets, and other proprietary information through copyright
protection, agreements with customers and suppliers, proprietary agreements with
employees and other security measures. While no intellectual property right of
ISD has been invalidated or declared unenforceable, there can be no assurance
that such rights will be upheld in the future.

The semiconductor industry is characterized by vigorous protection and
pursuit of intellectual property rights or positions, which have resulted in
significant and often protracted and expensive litigation. The only intellectual
property litigation currently pending against ISD is the Atmel litigation
described in "Legal Proceedings" below. However, ISD or its foundries may from
time to time be notified of additional claims that it may be infringing patents
or other intellectual property rights owned by other third parties. If it is
necessary or desirable, ISD may seek licenses under such patents or intellectual
property rights. However, there can be no assurance that licenses will be
offered or that the terms of any offered licenses will be acceptable to ISD. The
failure to obtain a license from a third party for technology used by ISD could
cause ISD to incur substantial liabilities and to suspend the manufacture or
shipment of products or the use by ISD's foundries of processes requiring the
technology. Furthermore, ISD may initiate claims or litigation against third
parties for infringement of ISD's proprietary rights or to establish the
validity of ISD's proprietary rights. Litigation, either as plaintiff or
defendant, could result in significant expense to ISD and divert the efforts of
ISD's technical and management personnel, whether or not such litigation is
determined in favor of ISD. In the event of an adverse result in any such
litigation, ISD could be required to pay substantial damages, cease the
manufacture, use and sale of infringing products, expend significant resources
to develop or acquire non-infringing technology, discontinue the use of certain
processes or obtain licenses to the infringing technology.

53
<PAGE> 59

There can be no assurance that ISD would be successful in such development or
acquisition or that such licenses would be available under reasonable terms, and
any such development, acquisition or license could require expenditures by ISD
of substantial time and other resources.

COMPETITION

The markets in which ISD competes are characterized by rapid technological
change, declining average selling prices and product obsolescence. Although ISD
believes that it currently faces no direct competition in direct analog storage,
a variety of digital approaches, including DSP and ADPCM, compete with certain
of ISD's products for certain applications. These digital approaches include
products from Oki Semiconductor, United Microelectronics Corporation, Toshiba
Semiconductor, NEC Technologies, Inc., DSP Group, Inc. and Winbond. Many of
ISD's customers may be purchasing products from both ISD and ISD's competitors.
ISD expects competition to increase in the future from existing competitors and
from other companies that may enter ISD's existing or future markets with
similar or substitute voice recording and playback solutions, such as voice mail
services, that may be less costly or provide additional features. ISD's
competitors include many large domestic and international companies that have
substantially greater financial, technical, marketing and other resources,
broader product lines and longer standing relationships with customers than ISD,
as well as emerging companies. ISD believes that the principal competitive
factors are product price, quality, performance and availability. ISD believes
that it competes favorably with respect to these factors in ISD's targeted
markets. ISD believes that its competitive strengths include the cost advantage
of its single-chip solution and the features and benefits of ChipCorder devices.

ISD believes that its ability to compete successfully in its targeted
markets depends on a number of factors, which include success in developing new
products, adequate foundry capacity and sources of raw materials, efficiency of
production, timing of new product introductions by ISD, its customers and its
competitors, the rate at which ISD's customers design ISD's products into their
products, the number and nature of ISD's competitors in a given market,
assertion of intellectual property rights and general market and economic
conditions. Although ISD believes that it competes favorably on the basis of
product cost and performance, there can be no assurance that ISD will be able to
compete successfully in the future.

EMPLOYEES

As of October 3, 1998, ISD had 146 full-time and 25 contract/temporary
employees. This included 51 employees in manufacturing, 32 in finance and
administration, 28 in sales and marketing, and 60 in research and development.
ISD's employees are not represented by a labor union and are not covered by any
collective bargaining agreement. ISD has never experienced a work stoppage and
believes its employee relations are good.

ISD's success depends to a significant degree upon the continued
contributions of members of its senior management and other key research and
development, sales, marketing and operations personnel. ISD has employment
agreements with certain executive officers and key personnel. However, the loss
of any of such persons could have a material adverse effect on ISD's business,
financial condition and results of operations. ISD believes that its future
success will depend in large part upon its ability to attract and retain highly
skilled managerial, engineering, sales and marketing personnel. Competition for
such personnel is intense, and there can be no assurance that ISD will be
successful in attracting and retaining such personnel. The loss of any key
employee, the failure of any key employee to perform in his or her current
position or ISD's inability to attract and retain new qualified employees could
have a material adverse effect on ISD's business, financial condition and
results of operations.

PROPERTIES

ISD's principal facilities consist of approximately 40,000 square feet of
space located in adjacent buildings in a business park in San Jose, California.
This space is leased pursuant to an agreement that expires in December 1999. ISD
also maintains domestic sales offices in Mendon, New York and Austin, Texas. ISD
leases approximately 3,500 square feet of space in an office building in
Herzelia, Israel for its Israeli design center. ISD believes that its current
space will be adequate for at least the next 12 months.

LEGAL PROCEEDINGS

In January 1995, Atmel notified ISD and Samsung of certain claims and
demanded that ISD and Samsung either negotiate licenses with Atmel or cease
manufacturing ISD's products at Samsung. ISD received an opinion from its patent
counsel, Blakely, Sokoloff, Taylor & Zafman, that ISD does not violate any of
the patents identified in Atmel's notice to ISD, and ISD believes the patent
claims are without merit. ISD also believes that the other claims in the notice
from Atmel were without merit, and its general counsel, on January 14, 1995,
after reviewing with appropriate senior and knowledgeable personnel at ISD the
factual information surrounding the other claims, provided a written response to
Atmel that these claims were without merit. Atmel filed a complaint on June 15,
1995 in the United States District Court for the Northern District of California
which alleges causes of action against ISD for patent infringement, trade secret
misappropriation, breach of written contract, breach of contract
implied-in-fact, unjust enrichment and declaratory relief. Atmel, in addition to
damages and injunctive relief, is seeking a declaration from the Court that
Atmel is a co-owner of ISD's ChipCorder products. All the causes of action
alleged in the complaint appear to be based on the same circumstances alleged in
the January 1995 Atmel notice. ISD believes the causes of action in the
complaint to be without merit and has had its general counsel file an answer
denying any wrongful conduct and asserting counterclaims for damage caused ISD
by Atmel's termination of the fabrication arrangement between the parties. The
Wafer Foundry Agreement between ISD and Samsung obligates Samsung to indemnify
and hold ISD harmless for any claims or suits on account of using any technical
information provided by Samsung. The Court has bifurcated the issues related to
liability and damages. On February 27, 1998, the Court issued a decision
construing the patent claims. ISD believes that this decision is at least in
part favorable to ISD. On April 14, 1998, the Court issued a decision
invalidating one of the asserted patents. Atmel has filed a Notice of Appeal of
that decision. On November 5, 1998, the Court granted summary judgment of
non-infringement in favor of ISD on the two remaining patents asserted. While
ISD does not believe the ultimate resolution of this matter will have a material
impact on its business or financial position, it may have a material adverse
impact on the results of operations in the period in which it is resolved.

On September 17, 1998, the Abraham Action was filed against ISD, its
directors and Winbond in the Santa Clara County Superior Court, Case No.
CV776731, bearing the caption "Jeffrey S. Abraham, individually and on behalf of
all persons similarly situated, Plaintiff, v. David L. Angel, Frederick B.
Bamber, Eugene J. Flath, Alan V. King, Eric J. Ochiltree, Frederick L. Zieber,
Information Storage Devices, Incorporated, Winbond Electronics Corporation,
Winbond International Corporation, Peaceful River Corporation, Pigeon Creek
Holding Company, Ltd., Winbond Acquisition Corporation, and Does 1 Through 100,
inclusive, Defendants." A copy of the complaint is attached to this Proxy
Statement as Appendix D. Mr. Abraham seeks to have the matter certified as a
class action of the holders of ISD Common Stock. Mr. Abraham alleges that the
intention of the ISD Defendants to pursue the Merger is in breach of their
fiduciary duties owed to holders of ISD Common Stock to take all necessary steps
to ensure that such holders will receive the maximum value realizable for their
shares in any extraordinary transaction involving ISD. Mr. Abraham alleges that
the Winbond Defendants knowingly aided and abetted the breaches of fiduciary
duty committed by the ISD Defendants. Mr. Abraham further alleges that the Cash
Consideration to be paid in connection with the Merger allegedly does not
reflect the fair value of ISD's equity, does not offer a control premium, is
less than the consideration proposed to be paid in a previous offer, and is less
than the intrinsic value of ISD's equity. He also alleges that the Merger is not
the result of arm's length negotiation and that it was fixed arbitrarily by ISD
and agreed to by the Defendants as part of the unlawful plan and scheme to
obtain the entire ownership of ISD at the lowest possible price. See Appendix D
for a full and complete statement of Mr. Abraham's allegations. The complaint
seeks a preliminary and permanent injunction against the Merger, rescission of
the Merger if it is consummated, an accounting for all profits realized or to be
realized by the Defendants as a result of the Merger, appointment of a committee
of ISD shareholders and their representatives to assist in the independent
evaluation of any transaction for ISD's shares, and unspecified compensatory
damages and attorneys' fees. ISD is not aware of any pending motion for a
preliminary injunction or other interim relief in connection with the Abraham
Action. There has been no formal discovery to date, although plaintiff has
served a request for production of documents on ISD. After review of the
complaint and based upon its understanding of the facts, ISD believes that the
allegations of the complaint are without merit and intends to defend the Abraham
Action vigorously.

INFORMATION CONCERNING WINBOND ELECTRONICS CORPORATION

Winbond Acquisition Corporation, a California corporation ("Merger Sub"),
is a wholly-owned subsidiary of Oriole Holding Corporation, a Delaware
corporation ("Oriole"). Merger Sub and Oriole were organized to acquire ISD and
have not conducted any unrelated activities since their organization. The
principal offices of Merger Sub and Oriole are located at 2727 N. First Street,
San Jose, CA 95134.

Oriole is a wholly-owned subsidiary of Winbond Int'l Corporation, a British
Virgin Islands corporation ("WIC"), which was formed in 1995 as part of a
reorganization of Winbond's operating structure in the United States. WIC is a
wholly-owned subsidiary of Winbond.

Winbond, a corporation organized in 1987 in the Republic of China in
Taiwan, is engaged in the design, development, manufacture and marketing of VLSI
IC's used in a variety of applications, including personal computer systems,
telecommunication systems and consumer electronics products. In addition to
manufacturing its proprietary products, Winbond offers foundry services for the
manufacture of ICs in accordance with the design and requirements of other
Taiwanese and non-Taiwanese IC companies. Winbond's principal executive offices
are located at No. 4, Creation Rd. III, Science-Based Industrial Park, Hsinchu,
Taiwan, Republic of China. Winbond's shares are listed on the Taiwan Stock
Exchange.

The total amount of funds required by Oriole to pay the Cash Consideration
(excluding shares held by Winbond and its subsidiaries) is estimated to be
approximately $64 million. Oriole will obtain such amounts from Winbond, which
will provide such amounts from its working capital and other customary financing
sources. As of June 30, 1998, Winbond had cash and cash equivalents calculated
in accordance with R.O.C. GAAP in excess of NT$13,527,487,959 (or
US$392,215,000, on the basis of NT$34.49 = US$1.00). None of Merger Sub, Oriole,
WIC, Winbond or their affiliates are subject to the informational filing
requirements of the Exchange Act and, accordingly, none of Merger Sub, Oriole,
WIC, Winbond or their affiliates files reports or other information with the
Commission relating to its business or financial condition. Winbond filed a
Schedule 13D with the Commission on May 22, 1998, as amended on June 30, 1998,
July 24, 1998 and September 14, 1998, to report the acquisition by various
subsidiaries of Winbond of shares representing approximately 14.1% of the shares
of ISD Common Stock outstanding. The shares of ISD Common Stock owned by the
subsidiaries of Winbond will be transferred to Oriole and will be canceled in
the Merger and no consideration will be paid pursuant to the Merger Agreement
for such shares.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Information Storage Devices, Inc.:

We have audited the accompanying balance sheets of Information Storage
Devices, Inc. (a California corporation) as of December 31, 1997 and 1996, and
the related statements of operations, shareholders' equity and cash flows for
each of the three years in the period ended December 31, 1997. These financial
statements and the schedule referred to below are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Information Storage Devices,
Inc. as of December 31, 1997 and 1996, and the results of its operations and its
cash flows for each of the three years in the period ended December 31, 1997, in
conformity with generally accepted accounting principles.

Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. Schedule II, Valuation and Qualifying
Accounts, is presented for purposes of complying with the Securities and
Exchange Commission's rules and is not part of the basic financial statements.
This schedule has been subjected to the auditing procedures applied in our
audits of the basic financial statements and, in our opinion, fairly states in
all material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.

NOTES TO FINANCIAL STATEMENTS

1. ORGANIZATION AND OPERATIONS:

ISD designs, develops, and markets semiconductor voice solutions based on
analog and digital technologies and mixed signal expertise. ISD's patented
ChipCorder(R) and CompactSPEECH(R) technologies enable solid state voice
recording and playback applications in the communications, consumer, and
industrial markets. The Company's markets are primarily in Europe, North
America, Japan, and South East Asia. The Company directs its marketing and
product development efforts toward products for the communications, consumer and
industrial markets. The Company distributes its products through a direct sales
and marketing organization and a worldwide network of sales representatives and
distributors.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

USE OF ESTIMATES

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 the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS

The Company considers all highly liquid investments with original
maturities of three months or less to be cash equivalents. Such investments
consisted of municipal bonds, commercial paper, bankers' acceptance notes and
certificates of deposit.

SHORT-TERM AND LONG-TERM INVESTMENTS

At December 31, 1997, approximately $26,253,000 of the Company's
investments in debt securities were classified as available-for-sale, and had
contractual maturities ranging from one month to two years from the date of
purchase by the Company. Available for sale debt securities are carried at fair
value with unrealized holding gains and losses reported as a separate component
of shareholders' equity. Debt securities are classified as held-to-maturity when
the Company has the positive intent and ability to hold the securities to
maturity. As of December 31, 1997, approximately $16,241,000 of the Company's
investments were classified as held-to-maturity and were carried at amortized
cost. Contractual maturities range from one month to two years from December 31,
1997. For all of the Company's investments, the fair value of the investments
approximated amortized cost and, as such, unrealized holding gains and losses
were insignificant. The fair value of the Company's investments was determined
based on quoted market prices at the reporting date for

F-7

those instruments. The carrying value of the Company's investments by major
security type at December 31, 1996 and December 31, 1997, was as follows (in
thousands):

Approximately $18,896,000 and $6,606,000 of the total investment in debt
securities is included in cash equivalents on the accompanying balance sheets as
of December 31, 1996 and 1997, respectively; the remainder is classified as
either short-term or long-term investments.

INVENTORIES

Inventories consist of material, labor and manufacturing overhead and are
stated at the lower of cost (first-in, first-out basis) or market. The
components of inventory are as follows (in thousands):

<TABLE>

Finished goods.................................... 3,902 3,462

$10,059 $7,742

</TABLE>

Inventories contained products in excess of the Company's current estimated
requirements and were fully reserved at December 31, 1996 and 1997. Due to
competitive pressures, it is possible that these estimates could change in the
near term.

PROPERTY AND EQUIPMENT

Depreciation is provided on property and equipment using the straight-line
method over the estimated useful lives of the assets of three (3) to seven (7)
years. Leasehold improvements are amortized over the useful lives of the
improvements or lease term, whichever is shorter. Betterments, renewals and
extraordinary repairs that extend the life of the asset are capitalized; other
repairs and maintenance are expensed. The cost and accumulated depreciation
applicable to assets retired are removed from the accounts and the gain or loss
on disposition recognized in income.

F-8

INFORMATION STORAGE DEVICES, INC.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

PATENT COSTS

Legal costs incurred in connection with filing the Company's patent claims
are recorded as patent costs. Upon receiving a determination that the Company's
claims have been approved or denied, these costs are either amortized over their
estimated useful lives or expensed.

REVENUE RECOGNITION

Revenues from product sales are generally recognized at the time of
shipment to the customer, with provisions for estimated returns and allowances.
Returns and allowances have not been significant to date. Certain of the
Company's sales are made to distributors under agreements allowing certain
rights of return and price protection on unsold merchandise. Accordingly, the
Company defers recognition of such sales until the merchandise is sold by the
distributor. The deferral of such sales is included in deferred revenue. Amounts
billed to the distributor upon shipment by the Company are included in accounts
receivable.

WARRANTY COSTS

Anticipated costs related to product warranties are charged to expense as
sales are recognized. The Company has not experienced significant warranty
claims to date.

CONCENTRATIONS OF RISK

Financial instruments that potentially subject the Company to
concentrations of credit risk consist principally of cash investments and trade
receivables. The Company has cash investment policies that limit cash
investments to low risk investments. With respect to trade receivables, the
Company performs ongoing credit evaluations of its customers' financial
condition and requires letters of credit whenever deemed necessary.
Additionally, the Company establishes an allowance for doubtful accounts based
upon factors surrounding the credit risk of specific customers, historical
trends and other information. As of December 31, 1997, ten customers accounted
for approximately 71% of the Company's trade receivables.

Of the Company's net revenues approximately 78% are supplied by wafers from
one foundry and 20% from another. Although there are a limited number of
foundries available that could manufacture the Company's products, management
believes that other suppliers can provide similar integrated circuits on
comparable terms. A change in suppliers, however, could cause a delay in
manufacturing and a possible loss of sales, which would affect operating results
adversely.

ACCRUED LIABILITIES

Accrued liabilities consisted of the following (in thousands):

NET INCOME (LOSS) PER SHARE

Effective December 31, 1997, the Company retroactively adopted the
provisions of Statement of Financial Accounting Standards No. 128 (SFAS),
"Earnings per Share". SFAS 128 requires companies to compute net income (loss)
per share under two different methods, basic and diluted; and to present per
share data for all periods for which an income statement is presented. Basic
earnings per share were computed by dividing net income or net loss by the
weighted average number of common shares outstanding during the
F-9
<PAGE> 74
INFORMATION STORAGE DEVICES, INC.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

period. Diluted earnings per share reflect the potential dilution that could
occur if the income were divided by the weighted average number of common and
potential common shares outstanding during the period. Diluted earnings per
share were computed by dividing net income by the weighted average number of
common shares and potential common shares from outstanding stock options for the
year ended December 31, 1995. Potential common shares were calculated using the
treasury stock method and represent incremental shares issuable upon exercise of
the Company's outstanding options. For the years ended December 31, 1996 and
1997, the diluted loss per share calculation excludes effects for outstanding
stock options as such inclusion would be anti-dilutive. The following table
provides reconciliation of the numerators and denominators used in calculating
basic and diluted earnings per share for the prior three years.

Options to purchase a weighted average of approximately 1.7 million and 2.4

respectively, but were not included in the computation of diluted earnings per
share as a result of their anti-dilutive effect on the loss available to common
shareholders.

3. ACQUISITION:

On March 28, 1997, the Company acquired the CompactSPEECH speech processor
product line from National Semiconductor for a cash purchase price of $5.1
million. The acquisition was accounted for under the purchase method of
accounting. A portion of the purchase price was allocated to assets acquired
based on their estimated fair value. In addition, $4.0 million of the purchase
price was allocated to in-process research and development projects that had not
reached technological feasibility and had no probable alternative future uses,
which the Company expensed at the date of the acquisition as a one-time
non-recurring charge. The remainder of the purchase price, $1.0 million, was
allocated to goodwill and will be amortized over five years on a straight-line
basis. Comparative pro forma information has not been presented, as the results
of operations for CompactSPEECH are not material to the Company's financial
statements.

4. LINE OF CREDIT:

In June 1997, the Company entered into a revolving line of credit agreement
with a bank under which it can borrow up to $15,000,000 based on eligible
investments. The line of credit is secured by substantially all of the Company's
assets, bears interest at LIBOR plus 1.25% (7.2% at December 31, 1997) and
expires on June 30, 1998. At December 31, 1997, there were no borrowings
outstanding under the line of credit and the Company's borrowing base was
approximately $17,700,000. The line of credit does not restrict the Company

from paying cash dividends on its capital stock and the only financial covenant
is to maintain a minimum of pledged investments of $17.7 million in the
Company's Liquidity Management account with the bank.

5. CAPITALIZED LEASE OBLIGATIONS:

The Company leases certain equipment under capital lease agreements. The
cost of equipment under capital leases included in property and equipment at
December 31, 1996 and December 31, 1997 was approximately $6,758,000 and
$7,408,000, respectively. Accumulated amortization of leased equipment at such
dates was approximately $3,955,000 and $5,358,000, respectively. Future minimum
lease payments together with the present value of the payments, as of December
31, 1997, are as follows (in thousands):

6. COMMITMENTS AND CONTINGENCIES:

OPERATING LEASES

The Company's principal facilities consist of approximately 40,000 square
feet of space located in adjacent buildings in a business park in San Jose,
California. This space is leased pursuant to an agreement that expires in
December 1999. The Company also maintains domestic sales offices in Mendon, New
York and Austin, Texas. The Company leases approximately 3,500 square feet of
space in an office building in Herzelia, Israel for its Israeli design center.
The leases for facilities and certain equipment are operating leases that expire
at various dates through 2000. Future minimum annual rental payments under
operating leases are as follows (in thousands):

totaled approximately $807,000, $1,380,000 and $1,627,000, respectively.

LITIGATION

In January 1995, Atmel Corporation ("Atmel") notified the Company and
Samsung Electronics Co., Ltd. ("Samsung") of certain claims and demanded that
the Company and Samsung either negotiate licenses with Atmel or cease
manufacturing the Company's products at Samsung. The Company received an opinion
from its patent counsel, Blakely, Sokoloff, Taylor & Zafman, that the Company
does not violate any of the patents identified in Atmel's notice to the Company,
and the Company believes the patent claims are without merit. The Company also
believes that the other claims in the notice from Atmel are without merit, and
its
F-11
<PAGE> 76
INFORMATION STORAGE DEVICES, INC.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

general counsel, on January 14, 1995, after reviewing with appropriate senior
and knowledgeable personnel at the Company the factual information surrounding
the other claims, provided a written response to Atmel that these claims were
without merit. Atmel filed a complaint on June 15, 1995 in the United States
District Court for the Northern District of California which alleges causes of
action against the Company for patent infringement, trade secret
misappropriation, breach of written contract, breach of contract
implied-in-fact, unjust enrichment and declaratory relief. Atmel, in addition to
damages and injunctive relief, is seeking a declaration from the Court that
Atmel is a co-owner of the Company's ChipCorder products. All the causes of
action alleged in the complaint appear to be based on the same circumstances
alleged in the January 1995 Atmel notice. The Company believes the causes of
action in the complaint to be without merit and has had its general counsel file
an answer denying any wrongful conduct and asserting counterclaims for damage
caused the Company by Atmel's termination of the fabrication arrangement between
the parties. The Court has bifurcated the issues related to liability and
damages, and the parties are in the process of conducting final discovery
relating to the liability issues. On February 27, 1998, the Court issued a
decision regarding the patent claims. The Company believes that this decision is
at least in part favorable to the Company. While the Company does not believe
the ultimate resolution of this matter will have a material impact on its
business or financial position, it may have a material adverse impact on the
results of operations in the period in which it is resolved.

7. EQUITY:

In January 1996, the Company's Board of Directors approved a stock
repurchase plan of up to one million shares of common stock. In addition, in
July 1996, the Board of Directors approved a stock repurchase plan of an
additional 100,000 shares of common stock. As of December 31, 1997 the Company
had repurchased 1,077,000 shares at an average price of $9.02 per share.

SHARES RESERVED FOR FUTURE ISSUANCE

As of December 31, 1997, the Company had reserved shares of its common
stock for the following purposes:

EMPLOYEE STOCK PURCHASE PLAN

In September 1994, the Company approved the Employee Stock Purchase Plan.
The plan reserved up to 170,000 shares of common stock for sale to eligible
employees at 85% of the lesser of the fair market value of the shares on the
first day of the offering period or the last day of the offering period.
Offerings under this plan commence on February 1 and August 1 of each year and
end on July 31 and January 31, respectively. As of December 31, 1997, 104,395
shares have been issued under this plan. The weighted average fair value of
shares sold in 1997 was $6.74.

STOCK OPTION PLANS

In December 1987, the Company adopted the 1987 Stock Option Plan (the "1987
Plan"). The 1987 Plan was terminated as to new issuances in February 1995.
Options granted under the 1987 Plan have a term of five

F-12
<PAGE> 77
INFORMATION STORAGE DEVICES, INC.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

years and vest over a vesting schedule determined by the Board of Directors,
generally four years. Options to purchase 144,387 shares were outstanding under
this plan at December 31, 1997.

In September 1994, the Company adopted the 1994 Equity Incentive Plan (the
"1994 Plan"), which became effective upon the closing of the Company's initial
public offering in February 1995 and serves as the successor to the 1987 Plan.
The Company has reserved 2,750,000 shares for issuance under the terms of the
1994 Plan, and may grant stock options, stock bonuses or issue restricted stock
to employees, officers, directors and consultants. Nonqualified options granted
under this plan have a term of ten years and must be issued at a price equal to
at least 85% of the fair market value of the Company's common stock at the date
of grant. Incentive stock options granted under this plan may be granted only to
employees of the Company, may have a term of up to ten years, and must be issued
at a price equal to the fair market value of the Company's common stock at the
date of grant. Restricted stock may be awarded to eligible personnel as
determined by the Board of Directors, and must be issued at a price equal to at
least 85% of the fair market value of the shares granted. Stock bonuses may be
awarded for services rendered to the Company under such terms as are established
by the Board of Directors.

In September 1994, the Company approved the 1994 Directors Stock Option
Plan. The Company reserved 120,000 shares of its common stock for issuance to
directors under this plan. This plan was amended effective March 21, 1996, the
"Amendment Effective Date", as per the annual shareholder meeting. Any option
grant, granted prior to January 1, 1996, will fully vest as to twenty-five
percent (25%) of the shares at the end of each full year following the grant
date, so long as the optionee continuously remains a director of the Company.
Any option grant, granted following the Amendment Effective Date, will vest
ratably at the end of each of the twelve months following the grant date and
will be fully vested on the first anniversary of the grant date, so long as the
optionee continuously remains a director of the Company until each such first
anniversary. Any option grant made during 1996 prior to the Amendment Effective
Date became fully vested on December 31, 1996.

During 1996, holders of options to purchase 1,368,639 shares of the
Company's common stock at exercise prices of $7.50 to $15.00 per share were
given the opportunity to exchange previously granted stock options for new
common stock options exercisable at $6.875 per share, the fair market value of
the common stock on the date of the exchange. Options to purchase 1,123,621
shares were exchanged.

Also included in the options granted during 1996 were options granted in
March 1996 to purchase 113,146 shares under the 1994 Plan that were granted
below fair market value. The Company recorded deferred compensation of
approximately $452,000 for the difference between the option price and fair
market value of common stock on the date of grant. The Company is expensing the
deferred compensation over the related vesting periods.

The Company accounts for the above plans under Accounting Principles Board
Opinion No. 25, under which no compensation cost has been recognized. Had
compensation cost for these plans been determined consistent with Statement of
Financial Accounting Standards (SFAS) No. 123, "Accounting for Stock-Based
Compensation", the Company's net income (loss) and net income (loss) per share
would have been reduced to the following pro forma amounts:

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

Because the SFAS No. 123 method of accounting has not been applied to
options granted prior to January 1, 1995, the resulting pro forma compensation
cost may not be representative of that to be expected in future years.

A summary of the Company's option plans at December 31, 1995, 1996 and 1997

The fair value of each option grant is estimated on the date of grant using
the Black-Scholes options pricing model with the following weighted-average
assumptions used for grants in 1995, 1996, and 1997, respectively: risk-free
interest rates of 6.45%, 5.57% and 5.66%; expected dividend yields of 0%;
expected lives of 1.5 years; expected volatility of 47%, 82%, and 58%.

WARRANTS

Holders of warrants to purchase a total of 328,981 shares of preferred
stock exercised such warrants in February 1995 on a net issuance basis for a
total of 236,730 shares of preferred stock, which converted to 78,910 shares of
common stock upon the closing of the Company's initial public offering in
February 1995. Additionally, holders of warrants to purchase 368,874 shares of
preferred stock (122,956 shares of common stock as converted) and 47,303 shares
of common stock exercised such warrants for cash prior to the closing of the
Company's initial public offering in February 1995. Net proceeds to the Company
for such exercises were approximately $591,000.

A warrant to purchase 25,000 shares of the Company's common stock was
granted on December 3, 1997 as part of the Company's investment in another
entity; these shares vest over a two year period and can be

exercised over a four year period. The fair value of this warrant was $100,000
and the amount has been recorded as part of the cost of the Company's investment
in the other entity.

SHAREHOLDER RIGHTS PLAN

During December 1995, the Company adopted a Shareholder Rights Plan, and
the Plan became effective in March of 1996 following the filing of the Plan with
the Securities and Exchange Commission. The Shareholder Rights Plan provides
that there shall be declared a dividend of one preferred share purchase right (a
"Right") for each outstanding share of common stock. Under certain conditions,
each Right may be exercised to purchase one one-hundredth of a share of Series A
Preferred Stock at an exercise price of $75. The Rights will be exercisable if a
person or group has acquired beneficial ownership of 15% or more of the common
stock or has announced a tender offer or exchange offer that if consummated
would result in such a person or group owning 15% or more of the common stock.
The Company generally will be entitled to redeem the Rights at $.01 per Right at
any time prior to the earlier of (i) the tenth day following public announcement
that a 15% stock position has been acquired and (ii) the expiration date of the
Rights on December 28, 2005.

If any person or group becomes a beneficial owner of 15% or more of the
common stock (except pursuant to a tender or exchange offer for all shares at a
price determined as fair by a majority of the outside members of the Board of
Directors), each Right not owned by such 15% stockholder will enable its holder
to purchase such number of shares of common stock as is equal to the exercise
price of the Right divided by one-half of the current market price of the common
stock on the date of the occurrence of the event. In addition, if the Company
engages in a merger or other business combination with another person or group
in which it is not the surviving corporation or in connection with which its
common stock is changed or converted, or if the Company sells or transfers 50%
or more of its assets or earning power to another person, each Right that has
not previously been exercised will entitle its holder to purchase such number of
shares of common stock of such other person as is equal to the exercise price of
the Right divided by one-half of the current market price of such common stock
on the date of the occurrence of the event.

The Company's net operating loss ("NOL") and tax credit carryforwards
expire at various dates through 2012. In accordance with certain provisions of
the Internal Revenue Code, as amended, a change in ownership of greater than 50%
of a company within a three year period results in an annual limitation on the
Company's ability to utilize its NOL carryforwards from tax periods prior to the
ownership change. Such a change in ownership occurred with respect to the
Company in July 1991 and February 1995. Accordingly, at December 31, 1997,
federal NOL carryforwards of approximately $1.6 million of the $13.5 million NOL
is restricted to annual amounts of approximately $150,000, which accumulate to
the extent not used and are subject to the expiration of these carryforwards.

At December 31, 1997, the Company had established a valuation allowance
against the gross deferred tax asset of $8,863,000. The valuation allowance was
established due to the Company's limited history of profitability, limitations
on the utilization of NOL carryforwards, which are restricted in use under the
Internal Revenue Code of 1986, and uncertainties regarding future operations due
to the increased competition within the Company's industry.

5. DERIVATIVES

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments

changes in the derivative's fair value be recognized currently in earnings
unless specific hedge accounting criteria are met. SFAS 133 is effective for
fiscal years beginning after June 15, 1999. The Company does not currently
utilize derivative instruments and therefore the adoption of SFAS 133 will not
have a material effect on the Company's financial statements. quantified the
impacts of adopting SFAS 133 on its financial statements and has not yet
determined the timing.

6. PROPOSED ACQUISITION

On September 11, 1998, the Company and Winbond Electronics Corporation
("Winbond"), Winbond Int'l Corporation, Oriole Holding Corporation ("Oriole")

Plan of Reorganization (the "Merger Agreement"), pursuant to which Merger Sub
will merge with and into the Company (the "Merger") and the Company will become
a wholly owned-subsidiary of Oriole. Upon consummation of the Merger, each
outstanding share of the Company's common stock not owned by Winbond or any of
its affiliates will be automatically canceled and converted into the right to
receive $7.50 in cash, subject to adjustment in certain events. The Merger is
subject to the approval of the Company's shareholders, and to certain regulatory
approvals and other customary closing conditions. All of the directors of the
Company and certain of executive officers of the Company, as well as Winbond,
Peaceful River Corp. and Pigeon Creek Holding Co., Ltd., have executed Voting
Agreements pursuant to which they have agreed to vote for the Merger.

ARTICLE II

MANNER AND BASIS OF CONVERTING SHARES OF CAPITAL STOCK

2.1 Effect on Capital Stock. At the Effective Time of the Merger, by
virtue of the Merger and without any action on the part of the holders of any
shares of the Company Common Stock:

(a) Cancellation of Company, WEC Group, Oriole and WAC Owned
Stock. All of the WEC Shares shall have been assigned and transferred to
Oriole or WAC, and all shares of Company Common Stock that are owned
directly or indirectly by the Company or by any of the WEC Group, Oriole,
WAC or any other subsidiary of WEC shall be canceled and extinguished
without conversion and no consideration shall be delivered in exchange
therefor.

(b) Conversion of Company Common Stock. Each of the Eligible Shares or
fractional share will be canceled and extinguished at the Effective Time of
the Merger and will be converted into the right to receive, upon surrender
of the certificate representing such share of Company Common Stock in the
manner provided in Section 2.2 hereof, an amount of cash equal to the Share
Price (without interest), on the terms and subject to the conditions set
forth in this Agreement (the "Merger Consideration");

(c) Effect on Company Preferred Stock. Any outstanding shares of
Company Preferred Stock shall be canceled and all authorized shares of
Company Preferred Stock shall be eliminated at the Effective Time of the
Merger.

(d) Capital Stock of WAC. All issued and outstanding shares of capital
stock of WAC shall continue to be issued and shall be converted into 1,000
shares of Common Stock of the Surviving Company. Each stock certificate of
WAC evidencing ownership of such certificates shall continue to evidence
ownership of such shares of capital stock of the Surviving Company.

(e) Dissenters' Rights. If holders of the shares of Company Common
Stock are entitled to dissenters' rights in connection with the Merger
under Section 1300 of the CGCL, any Dissenting Shares shall not be
converted into the right to receive cash as set forth in Section 2.1(b)
above, but shall be converted into the right to receive such consideration
as may be determined to be due with respect to such Dissenting Shares
pursuant to the CGCL. If, however, such dissenting shareholder withdraws
such shareholder's demand for appraisal or fails to perfect or otherwise
loses such shareholder's dissenters' rights, in any case pursuant to the
CGCL, such shareholder's shares shall be deemed to be converted as of the
Effective Time of the Merger into the right to receive the Merger
Consideration, without interest.

2.2 Surrender and Exchange of Certificates. As soon as practicable after
the Effective Time of the Merger, and after surrender to an agent appointed and
compensated by Oriole (the "Exchange Agent") of any certificate which prior to
the Effective Time of the Merger shall have represented any of the shares of
Company Common Stock, Oriole shall cause to be distributed to the person in
whose name such certificate is registered a check representing the Merger
Consideration determined pursuant to Section 2.1(b) above. Until surrendered as
contemplated by the preceding sentence, each certificate which immediately prior
to the Effective Time of the Merger shall have represented any of the shares of
Company Common Stock shall be deemed at and after the Effective Time of the
Merger to represent only the right to receive the Merger Consideration (without
interest) into which such shares shall have been converted hereunder. If any
payment is to be made to a Person other than the Person in whose name the
certificate surrendered in exchange therefor is registered, it will be a
condition of the payment thereof that the certificate so surrendered will be
properly endorsed and accompanied by all documents required by Oriole and the
Exchange Agent to evidence and effect such transfer and to evidence that any
applicable stock transfer taxes have been paid. If any certificate shall have
been lost, stolen or destroyed, upon the making of an affidavit of that fact by
the Person claiming such certificate to be lost, stolen or destroyed and, if
required by the Surviving Company, the posting by such Person of a bond in such
reasonable amount as the Surviving Company may direct as indemnity against any
claim that may be made against it with respect to such certificate, Oriole and
the Surviving Company will cause to be issued in exchange for such lost, stolen
or destroyed certificate the Merger Consideration (without interest) and unpaid
dividends and distributions on shares of Company Common Stock deliverable in
respect thereof, pursuant to this Agreement. Neither WEC nor Oriole or the
Surviving Company shall be liable to any

A-6
<PAGE> 97

Person in respect of any shares of Company Common Stock (or dividends or
distributions with respect thereto) in each case delivered to a public official
pursuant to any applicable abandoned property escheat or similar law. If any
certificate shall not have been surrendered prior to five years after the
Effective Time of the Merger (or immediately prior to such earlier date on which
any Merger Consideration, any cash payable to the holder of such certificate
pursuant to this Article II or any dividends or distributions payable to the
holder of such certificate would otherwise escheat to or become the property of
any Governmental Authority) any such Merger Consideration or cash, dividends or
distributions in respect of such certificate shall, to the extent permitted by
applicable law, become the property of the Surviving Company, free and clear of
all claims or interest of any Person previously entitled thereto.

2.3 Adjustment for Stock Splits, Etc. If, between the date of this
Agreement and the Effective Time of the Merger, the outstanding shares of
Company Common Stock shall have been changed into a different number of shares
or a different class by reason of any reclassification, recapitalization,
split-up, combination, exchange of shares or readjustment, or a stock dividend
thereon shall be declared with a record date within such period (an "Adjustment
Event") the cash consideration to be paid in the Merger in exchange for each
outstanding share of Company Common Stock, as provided in this Agreement, shall
be appropriately adjusted to reflect such Adjustment Event.

2.4 Stock Options. The Company agrees that it will use its best efforts to
deliver to WEC, prior to the Closing Date, consents from the holders of all
options outstanding on such date granted prior to the date of this Agreement
pursuant to the Directors Option Plan, Equity Incentive Plan and Option Plan
(the "Company Option Plans"), pursuant to which such holders consent to the
purchase of such option (and any related stock appreciation right) immediately
prior to the Effective Time of the Merger in exchange for a payment by the
Company, which the Company hereby agrees to make, in an amount (less any
applicable withholding taxes) equal to the excess, if any, of the Share Price
over the exercise price per share of Company Common Stock, multiplied by the
number of shares of Company Common Stock underlying such option immediately
prior to the Effective Time of the Merger (such options to be purchased herein
sometimes called the "Purchased Company Stock Options").

2.5 Share Price Adjustment. If the Company grants options or issues
additional shares of Capital Stock in excess of the amounts permitted under
Article V, subsection (b), without the prior written consent of WEC as required
by Article V of this Agreement, and such excess options are purchased pursuant
to the foregoing provisions and/or such additional shares are outstanding at the
Effective Time of the Merger, the amount paid by the Company to purchase such
additional options and/or additional shares shall reduce the Share Price
according to the following formula: The adjusted Share Price shall mean the
product of the Share Price multiplied by a fraction, the numerator of which is
equal to the sum of the number of outstanding shares of Company Common Stock
plus the shares subject to options outstanding on the date of this Agreement and
shares and options permitted to be granted or issued under Article V, subsection
(b) of this Agreement, and the denominator of which is equal to the sum of the
number of outstanding shares of Company Common Stock at the Effective Time of
the Merger plus a number of shares determined by dividing the total amount paid
for such additional options and/or additional outstanding shares by the Share
Price.

ARTICLE III

3.2 Capitalization.

(a) The authorized capital stock of the Company consists of 22,000,000
shares of Company Common Stock, 9,922,389 shares of which are outstanding and
5,000,000 shares of Company Preferred Stock, none of which are issued and
outstanding. All such outstanding shares have been duly authorized, are validly
issued, fully paid and nonassessable and not subject to preemptive rights
created by statute, the Company's Articles of Incorporation or Bylaws or any
agreement to which the Company is a party or by which it is bound.

(b) (i) There are no outstanding warrants, options, rights, securities,
agreements, subscriptions or other commitments pursuant to which the Company is
or may become obligated to issue, deliver or sell any additional shares of
capital stock or convertible debt of the Company or to issue, grant, extend or
enter into any such warrant, option, right, security, agreement, subscription or
other commitment and (ii) there are no outstanding options, rights, securities,
agreements or other commitments pursuant to which the Company is or may become
obligated to redeem, repurchase or otherwise acquire or retire any shares of

liability company, partnership, association, joint venture or other business
entity.

3.4 Validity of Agreement. The Company has full corporate power and
authority to execute and deliver this Agreement. This Agreement constitutes the
valid and binding obligation of the Company, enforceable in accordance with its
terms, except as enforcement may be limited by applicable bankruptcy laws or
other similar laws affecting creditors' rights generally and by principles of
equity. Subject to obtaining any necessary shareholder approval, the execution
and delivery of this Agreement by the Company, and the consummation of the
transactions contemplated hereby, have been duly authorized by all necessary
corporate action, and such execution and delivery do not require the consent,
approval or authorization of any Person, public authority or other entity. The
board of directors of the Company has determined that it is advisable and in the
best interest of the Company's shareholders for the Company to enter into the
Merger upon the terms and subject to the conditions of this Agreement, and has
properly and effectively waived the application as to the Merger of the
provisions of the Rights Agreement dated December 28, 1995, between the Company
and the First National Bank of Boston, as Rights Agent, and related documents
pursuant to the Company Shareholder Rights Plan; in particular, the Company's
board of directors has amended the Rights Agreement to provide that none of WEC,
Oriole, WAC, the WEC Group or any of their other Affiliates shall be deemed to
be an "Acquiring Person," as defined in the Rights Agreement, and such amendment
is enforceable against the Company and its shareholders by WEC.

appeal or investigation, at law or in equity, pending against the Company or
involving any of its business or properties, before any court, agency,
authority, arbitration panel or other tribunal, and, to the best knowledge of
the Company, none have been

A-8
<PAGE> 99

threatened. To the best knowledge of the Company, there are no facts which, if
known to shareholders, customers, governmental authorities or other persons,
would result in any such claim, dispute, action, proceeding, suit, appeal or
investigation which would have a material adverse effect on the condition
(financial or otherwise), business, net worth, assets, properties or operations
of the Company. The Company is not subject to any order, writ, injunction or
decree of any court, agency, authority, arbitration panel or other tribunal, or
in default with respect to any notice, order, writ, injunction or decree. The
Company has no knowledge, or any reliable information from which it could
reasonably be inferred, that Samsung Electronics Co., Ltd. ("Samsung") will not
fulfill its obligations under the Foundry Agreement between the Company and
Samsung dated November 12, 1996 (the "Foundry Agreement") to indemnify the
Company with respect to claims for patent infringement asserted against the

indirectly, take any of the following actions: (i) solicit, initiate, entertain,
encourage, participate in, conduct discussions with or engage in negotiations
with any Person relating to any merger, consolidation or business combination,
of or with the Company, or any purchase or sale of the Company's capital stock
or other equity securities or any purchase or sale of any of the Company's
material assets or any exchange offer or tender offer to the shareholders of the
Company or other similar transactions (any such transaction being hereafter
referred to as an "Acquisition Proposal"); (ii) provide any written or oral
information with respect to the Company to any Person (other than as
contemplated in this Agreement or required by applicable law) relating to any
Acquisition Proposal; or (iii) enter into any agreement with any Person with
regard to any Acquisition Proposal; provided, however, that nothing contained in

complying with Rule 14e-2 promulgated under the Exchange Act with regard to an
Acquisition Proposal; (B) engaging in any discussion or negotiations with, or
providing any information to, any Person in response to an unsolicited bona fide
written Acquisition Proposal by any such Person; or (C) recommending such an
unsolicited bona fide written Acquisition Proposal to the shareholders of the
Company or withdrawing or modifying its recommendation in favor of this
Agreement and the Merger in compliance with Section 6.3, if and only to the
extent that, in any such case as is referred to in clause (B) or (C), (i) a
majority of the members of the board of directors of the Company concludes in
good faith (after consultation with its financial advisors) that such
Acquisition Proposal is reasonably capable of being completed, taking into
account all legal, financial, regulatory and other aspects of the proposal and
the Person making the proposal, and would, if consummated, result in a
transaction more favorable to the Company's shareholders than the transaction
contemplated by this Agreement (any such more favorable Acquisition Proposal
being referred to in this Agreement as a "Superior Proposal"), (ii) a majority
of the members of the board of directors of the Company concludes in good faith
(after consultation with outside counsel) that such action is necessary for the
board of directors to act in a manner consistent with its fiduciary duties under
applicable law, (iii) prior to providing any information or data to any Person
in connection with an Acquisition Proposal by any such Person, such board of
directors receives from such Person an executed confidentiality agreement on
terms substantially similar to those contained in the confidentiality agreement
previously entered into between WEC and the Company in connection with their
consideration of the Merger, and (iv) prior to providing any information or data
to any Person or entering into discussions or negotiations with any Person, the
board of directors of the Company notifies WEC of such inquiries, expressions of
interest, proposals or offers received by, any such information requested from,
or any such discussions or negotiations to be initiated or continued with, any
of the Company's representatives indicating, in connection with such notice, the
name of such Person and the terms and conditions of any proposals or offers. The
Company agrees that it will immediately cease and cause to be terminated any
existing activities, discussions or negotiations with any parties conducted
heretofore with respect to any Acquisition Proposal. The Company agrees that it

A-19
<PAGE> 110

will take the necessary steps to promptly inform the officers, directors and
other representatives referred to in the first sentence hereof of the
obligations undertaken in this Section 6.12. The Company agrees that it shall
keep WEC informed, on a current basis, of the status and material terms of any
such proposals or offers and the status of any such discussions or negotiations.

6.13 Accountants' Letter. The Company shall direct and retain its
independent auditors, Arthur Andersen LLP, to deliver to WEC at the Effective
Time of the Merger, a letter dated as of that date, addressed to WEC, in form
and substance satisfactory to WEC, stating in effect:

(a) that they are, and during the period covered by their report(s)
relating to the financial statements included in or incorporated by
reference into the Proxy Statement they were, independent certified public
accountants with respect to the Company within the meaning of Regulation
S-X under the federal securities laws;

(b) that, in their opinion, the financial statements of the Company
included in or incorporated by reference into the Proxy Statement and
covered by their report included therein or incorporated by reference
therein comply as to form in all material respects with the applicable
accounting requirements of the Exchange Act and the rules and regulations
thereunder with respect to proxy statements;

(c) that, on the basis of procedures (but not an examination made in
accordance with generally accepted auditing standards) consisting of a
reading of the latest available unaudited consolidated interim financial
statements of the Company (with an indication of the date of the latest
available unaudited interim financial statements), a reading of the latest
available minutes of meetings of the stockholders and board of directors of
the Company and the committees of the board and unanimous written consents
thereof, if any, inquiries to certain officers and other employees of the
Company responsible for financial and accounting matters, and other
specified procedures and inquiries, nothing has come to their attention
that caused them to believe that:

(i) the unaudited consolidated financial statements of the Company
included in the Proxy Statement do not comply as to form in all material
respects with the applicable accounting requirements of the Exchange Act
and the rules and regulations under the Exchange Act, or such unaudited
financial statements were not prepared in accordance with generally
accepted accounting principles (except to the extent certain footnote
disclosures regarding any stub period may have been omitted in
accordance with the applicable rules of the SEC under the Exchange Act)
consistent in all material respects with those followed in the
preparation of the audited financial statements of the Company included
therein or incorporated by reference therein, or are not a fair
presentation of the information purported to be shown; or

(ii) there was any change in the capital stock or debt of the
Company or any decrease in the net current assets of stockholders'
equity of the Company and a specified date not more than 10 business
days prior to the date of such letter, each as compared with the amounts
shown in the balance sheet of the Company at January 1, 1998, other than
as disclosed in this Agreement or any change or decrease (which shall be
set forth in such letter) which WEC in its sole discretion shall accept;

(d) that they have reviewed (in accordance with established
professional standards and procedures under Rule 10-01(d) of SEC Regulation
S-X) the Company's net sales, net earnings, and net earnings per share (on
a basic and a fully diluted basis) of the Company's Common Stock during the
period from January 1, 1998 to October 3, 1998;

(e) that they have reviewed (in accordance with established
professional standards and procedures under Rule 10-01(d) of SEC Regulation
S-X) the adequacy of all reserves on the Company's books at October 3, 1998
including, without limitation, inventory and litigation reserves; and

(f) that they have compared specific numerical data and financial
information pertaining to the Company set forth in the Proxy Statement,
which have been specified by WEC prior to the date of this Agreement, to
the extent that such data and information may be derived from the general
accounting

A-20
<PAGE> 111

records of the Company, and excluding any questions requiring an
interpretation by legal counsel, with the results obtained from the
application of specified readings, inquiries, and other appropriate
procedures (which procedures do not constitute an examination in accordance
with generally accepted auditing standards) set forth in the letter, and
found them to be in agreement.

6.14 Closing Conditions. Each party covenants and agrees to take such
actions, or to cause its agents or representatives to take such actions, as may

a condition of the payment thereof that the certificate so surrendered will be

required by the Surviving Corporation, the posting by such Person of a bond in
such reasonable amount as the Surviving Corporation may direct as indemnity

Oriole and the Surviving Corporation will cause to be issued in exchange for
such lost, stolen or destroyed certificate the Merger Consideration and unpaid
dividends and distributions on shares of ISD Common Stock deliverable in respect
thereof, pursuant to this Agreement. Neither WEC nor Oriole or the Surviving
Corporation shall be liable to any Person in respect of any shares of ISD Common
Stock (or dividends or distributions with respect thereto) in each case
delivered to a public official pursuant to any applicable abandoned property
escheat or similar law. If any certificate shall not have been surrendered prior
to five years after the Effective Time of the Merger (or immediately prior to
such earlier date on which any Merger Consideration, any cash payable to the
holder of such certificate pursuant to this Article IV or any dividends or
distributions payable to the holder of such certificate would otherwise escheat
to or become the property of any governmental authority) any such Merger
Consideration or cash, dividends or distributions in respect of such certificate
shall, to the extent permitted by applicable law, become the property of the
Surviving Corporation, free and clear of all claims or interest of any Person
previously entitled thereto.

action by the shareholders, and (c) in the case of any meeting at which
directors are to be elected, the names of the nominees whom, at the time of the
notice, management intends to present for election.

If action is proposed to be taken at any meeting for approval of (i) a
contract or transaction in which a director has a direct or indirect financial
interest, pursuant to Section 310 of the California General

A-39
<PAGE> 130

Corporation Law (the "Code"), (ii) an amendment to the articles of
incorporation, pursuant to Section 902 of the Code, (iii) a reorganization of
the corporation, pursuant to Section 1201 of the Code, (iv) a voluntary
dissolution of the corporation, pursuant to Section 1900 of the Code, or (v) a
distribution in dissolution other than in accordance with the rights of
outstanding preferred shares, pursuant to Section 2007 of the Code, the notice
shall also state the general nature of that proposal.

SECTION 2.5 Manner of Giving Notice; Affidavit of Notice. Notice of any
meeting of shareholders shall be given either personally or by first-class mail,
or if the corporation has outstanding shares held of record by five hundred
(500) or more persons (determined as provided in Section 605 of the Code) on the
record date for the shareholders' meeting, notice may be sent by third-class
mail, or by telegraphic or other written communication, charges prepaid,
addressed to the shareholder at the address of that shareholder appearing on the
books of the corporation or given by the shareholder to the corporation for the
purpose of notice. If no such address appears on the corporation's books or is
given, notice shall be deemed to have been given if sent to that shareholder by
first-class mail or telegraphic or other written communication to the
corporation's principal executive office, or if published at least once in a
newspaper of general circulation in the county where that office is located.
Notice shall be deemed to have been given at the time when delivered personally
or deposited in the mail or sent by telegram or other means of written
communication.

If any notice addressed to a shareholder at the address of that shareholder
appearing on the books of the corporation is returned to the corporation by the
United States Postal Service marked to indicate that the United States Postal
Service is unable to deliver the notice to the shareholder at that address, all
future notices or reports shall be deemed to have been duly given without
further mailings if the same shall be available to the shareholder on written
demand of the shareholder at the principal executive office of the corporation
for a period of one (1) year from the date of the giving of the notice. An
affidavit of the mailing or other means of giving any notice of any
shareholders' meeting, executed by the secretary, assistant secretary or any
transfer agent of the corporation giving the notice, shall be prima facie
evidence of the giving of such notice.

SECTION 2.6 Waiver of Notice or Consent by Absent Shareholders. The
transactions of any meeting of shareholders, however called and noticed, and
wherever held, shall be as valid as though done at a meeting duly held after
regular call and notice, if a quorum is present either in person or by proxy,
and if, either before or after the meeting, each of the persons entitled to vote
at the meeting, who was not present in person or by proxy, signs a written
waiver of notice or a consent to the holding of the meeting or an approval of
the minutes of the meeting. The waiver of notice or consent need not specify
either the business to be transacted or the purpose of any annual or special
meeting of shareholders, except that if action is taken or proposed to be taken
for approval of any of those matters specified in the second paragraph of
Section 2.4 of these bylaws, the waiver of notice or consent shall state the
general nature of the proposal. All such waivers, consents and approvals shall
be filed with the corporate records or made a part of the minutes of the
meeting.

Attendance by a person at a meeting shall also constitute a waiver of
notice of that meeting, except when the person objects, at the beginning of the
meeting, to the transaction of any business because the meeting is not lawfully
called or convened, and except that attendance at a meeting is not a waiver of
any right to object to the consideration of a matter not included in the notice
of the meeting, if that objection is expressly made at the meeting.

SECTION 2.7 Quorum. The representation in person or by proxy of a majority
of the shares entitled to vote shall constitute a quorum for the transaction of
business at a meeting of the shareholders. The shareholders present at a duly
called or held meeting at which a quorum is present may continue to transact
business until adjournment, notwithstanding the withdrawal of enough
shareholders to leave less than a quorum, if any action taken (other than
adjournment) is approved by at least a majority of the shares required to
constitute a quorum.

Any shareholders' meeting, annual or special, whether or not a quorum is
present, may be adjourned from time to time by the vote of a majority of the
shares represented in person or by proxy at that meeting, but in the absence of
a quorum, no other business may be transacted, except as provided above.

A-40
<PAGE> 131

When any shareholders' meeting is adjourned, notice of the adjourned
meeting need not be given if the time and place to which the meeting is
adjourned are announced at the meeting at which the adjournment is taken, unless
(a) the adjournment is for forty-five (45) days or more from the date set for
the original meeting or (b) after the adjournment a new record date is fixed for
the adjourned meeting. In those cases, notice of the adjourned meeting shall be
given pursuant to Section 2.5 to each shareholder entitled to vote at the
adjourned meeting.

SECTION 2.8 Voting.

(a) Procedures. The shareholders entitled to vote at any meeting of
shareholders shall be determined in accordance with the provisions of Section
2.10, subject to the provisions of Sections 702 through 704, inclusive, of the
Code (relating to voting shares held by a fiduciary, in the name of a
corporation or in joint ownership). The shareholders' vote may be by voice vote
or by ballot; provided, however, that any election for directors must be by
ballot if demanded by any shareholder at the meeting before the voting has
begun. On any matter other than the election of directors, any shareholder may
vote part of the shares in favor of the proposal and refrain from voting the
remaining shares or vote them against the proposal, but if the shareholder fails
to specify the number of shares which the shareholder is voting affirmatively,
it will be conclusively presumed that the shareholder's approving vote is with
respect to all shares which the shareholder is entitled to vote. Except as
provided in Section 2.7 or in this Section 2.8, the affirmative vote of the
majority of the shares represented and voting at a duly held meeting at which a
quorum is present (which shares voting affirmatively also constitute at least a
majority of the required quorum) shall be the act of the shareholders, unless
the vote of a greater number, or voting by classes, is required by the Code or
by the articles of incorporation.

(b) Cumulative Voting. Shareholders entitled to vote at any election of
directors shall have the right to cumulate their votes and give one candidate a
number of votes equal to the number of directors to be elected multiplied by the
number of votes to which their shares are normally entitled, or to distribute
their votes on the same principle among as many candidates as they shall think
fit; provided, however, that no shareholder shall be entitled to cumulate votes
unless the candidates' names shall have been placed in nomination prior to
commencement of the voting and at least one shareholder shall have given notice
at the meeting prior to the voting of that shareholder's intention to vote
cumulatively. If any shareholder has given such a notice, then every shareholder
entitled to vote may cumulate votes for candidates placed in nomination and give
one candidate a number of votes equal to the number of directors to be elected
multiplied by the number of votes to which that shareholder's shares are
entitled, or distribute the shareholder's votes on the same principle among any
or all of the candidates, as the shareholder thinks fit. The candidates
receiving the highest number of votes, up to the number of directors to be
elected, shall be elected. If there are more candidates for than vacancies on
the board, the vacancies shall be filled by the candidates receiving the highest
number of affirmative votes.

(c) Proxies. Every person entitled to vote shall have the right to do so
either in person or by one or more agents authorized by a written proxy signed
by such person and filed with the secretary of the corporation. A proxy shall be
deemed signed if the shareholder's name is placed on the proxy (whether by
manual signature, typewriting, telegraphic transmission, or otherwise) by the
shareholder or the shareholder's attorney-in-fact. A validly executed proxy
which does not state that it is irrevocable shall continue in full force and
effect unless (i) revoked by the person executing it, prior to the vote pursuant
to that proxy, by a writing delivered to the corporation stating that the proxy
is revoked, or by a subsequent proxy executed by, or attendance at the meeting
and voting in person by, the person executing the proxy, or (ii) written notice
of the death or incapacity of the maker of that proxy is received by the
corporation before the vote pursuant to that proxy is counted; provided,
however, that no proxy shall be valid after the expiration of eleven (11) months
from the date of the proxy unless otherwise provided in the proxy. The
revocability of a proxy that states on its face that it is irrevocable shall be
governed by the provisions of Sections 705(e) and (f) of the Code.

SECTION 2.9 Action Without Meeting. Except as otherwise provided in this
Section 2.9, any action which may be taken at any meeting of shareholders may be
taken without a meeting and prior notice, if a consent in writing, setting forth
the action so taken, shall be signed by the holders of the outstanding shares
having not less than the minimum number of votes that would be necessary to
authorize or take such action at

A-41
<PAGE> 132

a meeting at which all shares entitled to vote thereon were present and voted.
All such consents shall be filed with the secretary of the corporation and shall
be maintained in the corporate records. Any shareholder giving a written
consent, or the shareholder's proxy holders, or a transferee of the shares, or a
personal representative of the shareholder, or their respective proxy holders,
may revoke the consent by a writing received by the secretary of the corporation
before written consents of the number of shares required to authorize the
proposed action have been filed with the secretary.

Unless consents of all shareholders entitled to vote have been solicited in
writing, (a) prompt notice shall be given, in accordance with the provisions of
Section 2.5, of actions taken without a meeting by less than unanimous written
consent, to those shareholders entitled to vote who have not consented in
writing; and (b) in the case of any shareholder approval which is (i) obtained
without a meeting by less than unanimous written consent and (ii) pursuant to
Code Section 310 (approval of contracts or transactions with an interested
director), Section 317 (indemnification of agents of the corporation), Section
1201 (reorganization) or Section 2007 (plan of distribution on dissolution not
in accordance with the rights of outstanding preferred shares), notice of such
approval shall be given at least ten (10) days before the consummation of the
action authorized by such approval.

Directors may not be elected by written consent except by unanimous written
consent of all shares entitled to vote for their election; provided, however,
that a director may be elected at any time to fill a vacancy that has not been
filled by the directors, except for a vacancy created by removal, by written
consent of a majority of the outstanding shares entitled to vote.

SECTION 2.10 Record Date.

(a) Established by the Board of Directors. In order that the corporation
may determine the shareholders entitled to notice of, or to vote at, any meeting
or entitled to receive payment of any dividend or other distribution or
allotment of any rights, or entitled to exercise any rights in respect of any
other lawful action, the board of directors may fix, in advance, a record date,
which shall not be more than sixty (60) nor less than ten (10) days before the
date of such meeting, nor more than sixty (60) days prior to any other action.

(b) Established by Operation of Law. If no record date is fixed:

(i) the record date for determining shareholders entitled to notice of
or to vote at a meeting of shareholders shall be at the close of business
on the business day preceding the day on which notice is given or, if
notice is waived, at the close of business on the business day preceding
the day on which the meeting is held;

(ii) the record date for determining shareholders entitled to give
consent to corporate action in writing without a meeting, when no prior
action by the board of directors has been taken, shall be the day on which
the first written consent is given; and

(iii) the record date for determining shareholders for any other
purpose shall be at the close of business on the day on which the board of
directors adopts the resolution relating thereto, or the sixtieth (60th)
day prior to the date of such other action, whichever is later.

(c) Effect of Determination of Record Date. Shareholders of record at the
close of business on the record date are entitled to notice and to vote, or to
receive the dividend, distribution or allotment of rights, or to exercise the
rights, as the case may be, notwithstanding any transfer of any shares on the
books of the corporation after the record date, except as otherwise provided by
agreement or in the Code.

SECTION 2.11 Inspectors of Election. Before any meeting of shareholders,
the board of directors may appoint an inspector or inspectors of election to act
at the meeting or its adjournment. If no inspector of election is so appointed,
the chairman of the meeting may, and on the request of any shareholder or a
shareholder's proxy shall, appoint an inspector or inspectors of election to act
at the meeting. The number of inspectors shall be either one (1) or three (3).
If inspectors are appointed at a meeting pursuant to the request of one (1) or
more shareholders or proxies, the holders of a majority of shares or their
proxies present at the meeting shall determine whether one (1) or three (3)
inspectors are to be appointed. If any person appointed

A-42
<PAGE> 133

as inspector fails to appear or fails or refuses to act, the chairman of the
meeting may, and upon the request of any shareholder or a shareholder's proxy
shall, appoint a person to fill that vacancy.

Such inspectors shall:

(a) Determine the number of shares outstanding and the voting power of
each, the number of shares represented at the meeting, the existence of a
quorum, and the authenticity, validity and effect of proxies;

(b) Receive votes, ballots or consents;

(d) Count and tabulate all votes or consents;

(e) Determine when the polls shall close;

(f) Determine the result; and

(g) Do any other acts that may be proper to conduct the election or
vote with fairness to all shareholders.

ARTICLE III

DIRECTORS

SECTION 3.1 Powers. Subject to the provisions of the Code and to any
limitations in the articles of incorporation or these bylaws requiring
shareholder authorization or approval of a particular action, the business and
affairs of the corporation shall be managed, and all corporate powers shall be
exercised, by or under the direction of the board of directors. The board of
directors may delegate the management of day-to-day operation of the business of
the corporation to a management company or other person; provided, however, that
the business and affairs of the corporation shall be managed, and all corporate
powers shall be exercised, under the ultimate direction of the board of
directors.

SECTION 3.2 Number and Qualification of Directors. This corporation shall
have a fixed number of three (3) directors until changed by an amendment to the
articles of incorporation, or by an amendment to this Section 3.2 adopted by
holders of a majority of the outstanding shares entitled to vote. After the
issuance of shares, a bylaw specifying or changing a fixed number of directors
or the maximum or minimum number or changing from a fixed to a variable board or
vice versa may only be adopted by holders of a majority of the outstanding
shares entitled to vote. The directors need not be shareholders of this
corporation.

SECTION 3.3 Election and Term of Office. The directors shall be elected at
each annual meeting of shareholders to hold office until the next annual
meeting. Subject to the provisions of Sections 3.5 and 3.6, each director shall
hold office until the expiration of the term for which elected and until a
successor has been elected.

SECTION 3.4 Vacancies. Except for a vacancy created by the removal of a
director, vacancies in the board of directors may be filled by a majority of the
remaining directors, whether or not less than a quorum, or by a sole remaining
director. The shareholders shall elect a director or directors to fill any
vacancy created by removal, and the shareholders may elect a director or
directors at any time to fill a vacancy not filled by the directors, but such
election, if by written consent, shall be pursuant to the provisions of Section
2.9. Each director so elected shall hold office until the next annual meeting of
the shareholders and until a successor has been elected.

SECTION 3.5 Resignation. Any director may resign effective upon giving
written notice to the chair of the board, the president, the secretary or the
board of directors, unless the notice specifies a later time for that
resignation to become effective. If the resignation is effective at a future
time, a successor may be elected to take office when the resignation becomes
effective.

A-43
<PAGE> 134

SECTION 3.6 Removal. The board of directors may declare vacant the office
of a director who has been declared of unsound mind by order of court, or who
has been convicted of a felony. Any or all of the directors may be removed
without cause by an affirmative vote of a majority of the outstanding shares
entitled to vote; provided, however, that unless the entire board is removed, no
individual director may be removed when the votes cast against removal, or not
consenting in writing to such removal, would be sufficient to elect such
director if voted cumulatively at an election at which the same total number of
votes were cast (or, if such action is taken by written consent, all shares
entitled to vote were voted) and either the entire number of directors elected
at the most recent annual meeting of shareholders, or if greater, the number of
directors for whom removal is being sought, were then being elected.

SECTION 3.7 Place of Meetings. Meetings of the board of directors may be
held at any place which has been designated in the notice of the meeting, or, if
not stated in the notice or if there is no notice, designated in the bylaws or
by resolution of the board of directors. In the absence of designation, meetings
shall be held at the principal executive office of the corporation.

SECTION 3.8 Regular Meetings. Regular meetings of the board of directors
shall be held without notice at such time and place as shall be determined from
time to time by the board of directors.

SECTION 3.9 Special Meetings; Notice. Special meetings of the board of
directors may be called at any time by the chair of the board or the president
or any vice president or the secretary or any two directors. Notice of the time
and place of all special meetings shall be given to each director by any of the
following means:

system or other system or technology designed to record and communicate
messages, telegraph, facsimile, electronic mail, or other electronic means
at least forty-eight (48) hours prior to the time of the meeting; or

(b) By first-class mail, postage prepaid, at least four (4) days prior
to the time of the meeting.

Any oral notice given personally or by telephone may be communicated either
to the director or to a person at the office of the director who the person
giving the notice has reason to believe will promptly communicate it to the
director. The notice need not specify the purpose or the place of the meeting,
if the meeting is to be held at the principal executive office of the
corporation.

SECTION 3.10 Waiver of Notice. Notice of a meeting need not be given to
any director who, either before or after the meeting, signs a written waiver of
notice or a consent to holding the meeting or an approval of the minutes
thereof. All such waivers, consents and approvals shall be filed with the
corporate records or made a part of the minutes of the meeting. Notice of a
meeting also need not be given to any director who attends the meeting without
protesting, before or at its commencement, the lack of notice to that director.

SECTION 3.11 Participation by Telephone. Members of the board of directors
may participate in a meeting through use of conference telephone, electronic
video screen communication, or other communications equipment. Participation in
a meeting pursuant hereto constitutes presence in person at that meeting if all
of the following apply:

(a) Each member participating in the meeting can communicate with all
of the other members concurrently.

(b) Each member is provided the means of participating in all matters
before the board, including the capacity to propose, or to interpose an

(i) A person communicating by telephone, electronic video screen,
or other communications equipment is a director entitled to participate
in the board meeting; and

(ii) All statements, questions, actions, or votes were made by that
director and not by another person not permitted to participate as a
director.

SECTION 3.12 Quorum and Action at Meeting. A majority of the authorized
number of directors fixed by Section 3.2 shall constitute a quorum for the
transaction of business, except to adjourn as provided in Section 3.13 of these
bylaws. Subject to the provisions of the Code, an act or decision done or made
by a majority of the directors present at a meeting duly held at which a quorum
is present shall be regarded as the act of the board of directors. A meeting at
which a quorum is initially present may continue to transact business
notwithstanding the withdrawal of directors, if any action taken is approved by
at least a majority of the required quorum for that meeting.

SECTION 3.13 Adjournment/Notice of Adjournment. A majority of the
directors present, whether or not constituting a quorum, may adjourn any meeting
to another time and place. Notice of the time and place of holding an adjourned
meeting need not be given, unless the meeting is adjourned for more than
twenty-four (24) hours, in which case notice of the time and place shall be
given before the time of the adjourned meeting, in the manner specified in
Section 3.9 of these bylaws, to the directors who were not present at the time
of the adjournment.

SECTION 3.14 Action Without Meeting. An action required or permitted to be
taken by the board of directors may be taken without a meeting, if all members
of the board individually or collectively consent in writing to that action. The
written consent or consents shall be filed with the minutes of the board.
Actions by written consent shall have the same force and effect as a unanimous
vote of the directors.

SECTION 3.15 Committees. The board of directors may, by resolution adopted
by a majority of the authorized number of directors, designate one or more
committees, each consisting of two or more directors and each of which, except
to the extent provided in the resolution and as limited by Section 311 of the
Code, shall have all the authority of the board of directors. Further, the board
may designate one or more directors as alternate members of any committee, who
may replace any absent member at any meeting of the committee. Each committee
shall serve at the pleasure of the board.

SECTION 3.16 Meetings and Action of Committees. Meetings and action of
committees shall be governed by, and held and taken in accordance with, the
provisions of Article III of these bylaws, with such changes in the context of
these bylaws as are necessary to substitute the committee and its members for
the board of directors and its members, except that the time for regular
meetings of committees may be determined either by resolution of the board of
directors or by resolution of the committee. Special meetings of committees may
also be called by resolution of the board of directors. Notice of special
meetings of committees shall also be given to all alternate members, who shall
have the right to attend all meetings of the committee. Minutes shall be kept of
each meeting of any committee and shall be filed with the corporate records. The
board of directors may adopt such other rules for the governance of any
committee as are not inconsistent with the provisions of these bylaws.

SECTION 3.17 Compensation and Expenses of Directors. Directors and members
of committees shall not receive compensation for their services or reimbursement
for their expenses except in amounts fixed or determined by resolution of the
board of directors. This Section 3.17 shall not be construed to preclude any
director from serving the corporation in any other capacity as an officer,
agent, employee or otherwise, and receiving compensation for those services.

SECTION 3.18 Approval of Loans to Officers. The corporation may, upon the
approval of the board of directors alone, make loans of money or property to, or
guarantee the obligations of, any officer of the corporation or its parent or
subsidiary, whether or not a director, or adopt an employee benefit plan or
plans authorizing such loans or guaranties provided that (i) the board of
directors determines that such a loan or guaranty or plan may reasonably be
expected to benefit the corporation, (ii) the corporation has outstanding shares
held of record by 100 or more persons (determined as provided in Section 605 of
the Code) on the date of approval by the board of directors, and (iii) the
approval of the board of directors is by a vote sufficient without counting the
vote of any interested director or directors.

and perform such other duties as may be properly prescribed by the board of

SECTION 5.4 Checks, Drafts, Evidences of Indebtedness. All checks, drafts
or other orders for payment of money, notes or other evidences of indebtedness,
issued in the name of, or payable to, the corporation, shall be signed or
endorsed by such person or persons and in such manner as, from time to time,
shall be determined by resolution of the board of directors.

SECTION 5.5 Execution of Corporate Contracts and Instruments. Subject to
restrictions on corporate loans and guarantees to directors, officers, employees
or shareholders as provided by Section 315 of the Code, the board of directors
may authorize any officer or officers or agent or agents, or appoint an
attorney-in-fact or attorneys-in-fact, to enter into any contract or execute any
instrument in the name of, and on behalf of, the corporation, and this authority
may be general or confined to specific instances; and unless so authorized or

A-47
<PAGE> 138

appointed, or unless afterwards ratified by the board of directors, no officer,
agent or employee shall have any power or authority to bind the corporation by
any contract or engagement or to pledge its credit or to render it liable for
any purpose or for any amount.

SECTION 5.6 Certificates for Shares. Every holder of shares in the
corporation shall be entitled to have a certificate signed in the name of the
corporation by the chair or vice chair of the board or the president or a vice
president and by the chief financial officer or an assistant treasurer or the
secretary or any assistant secretary, certifying the number of shares and the
class or series of shares owned by the shareholder. Any or all of the signatures
on the certificate may be facsimile. In case any officer, transfer agent or
registrar who has signed or whose facsimile signature has been placed upon a
certificate shall have ceased to be that officer, transfer agent or registrar
before such certificate is issued, it may be issued by the corporation with the
same effect as if such person were an officer, transfer agent or registrar at
the date of issue.

SECTION 5.7 Lost, Stolen or Destroyed Certificates. The corporation may
issue a new share certificate or a new certificate for any other security in the
place of any certificate previously issued by it and alleged to have been lost,
stolen or destroyed. As a condition to the issuance of a new share certificate,
the corporation may require the owner of the lost, stolen or destroyed
certificate or the owner's legal representative to give the corporation a bond
(or other adequate security) sufficient to indemnify it against any claim that
may be made against it (including any expense or liability) on account of the
alleged loss, theft or destruction of any such certificate or the issuance of
such replacement certificate.

such form as shall be prescribed and adopted by the board of directors.

SECTION 5.9 Construction and Definitions. Unless the context requires
otherwise, the general provisions, rules of construction and definitions in the
Code shall govern the construction of these bylaws. Without limiting the
generality of this provision, the singular number includes the plural, the
plural includes the singular, and the term "person" includes both a corporation
and a natural person.

ARTICLE VI

INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES AND OTHER AGENTS

The corporation is authorized to indemnify each of its agents against
expenses, judgments, fines, settlements and other amounts, actually and
reasonably incurred by such person by reason of such person's having been made
or having been threatened to be made a party to a proceeding in excess of
indemnification expressly permitted by Section 317 of the Code, to the fullest
extent permissible under California law, and the corporation shall advance the
expenses reasonably expected to be incurred by such agent in defending any such
proceeding upon receipt of the undertaking required by subdivision (f) of
Section 317 of the Code. The terms "agent", "proceeding" and "expenses" used in
this Article VI shall have the same meaning as such terms in said Section 317 of
the Code. The corporation may purchase and maintain insurance on behalf of any
agent of the corporation against any liability asserted against, or incurred by,
the agent in such capacity or arising out of the agent's status as such, whether
or not the corporation would have the power to indemnify the agent against that
liability under the provisions of Section 317 of the Code.

ARTICLE VII

as provided in Section 7.1, bylaws other than a bylaw or amendment thereof

September 10, 1998

PRIVILEGED & CONFIDENTIAL

Board of Directors
Information Storage Devices, Inc.
2045 Hamilton Avenue
San Jose, CA 95125

Dear Members of the Board:

You have asked our opinion with respect to the fairness to the Holders of
ISD Common Stock (as defined below), from a financial point of view and as of
the date hereof, of the Cash Consideration (as defined below) to be received
pursuant to an Agreement and Plan of Merger (the "Merger Agreement") among
Winbond Electronics Corporation ("Parent"), Winbond Holding Company America,
Winbond Acquisition Corporation ("Purchaser") and Information Storage Devices,
Inc. ("ISD"). The Merger Agreement provides for the merger of Purchaser and ISD
pursuant to which ISD will become a wholly-owned subsidiary of Parent (the
"Merger"). In the Merger, each outstanding share of Common Stock of ISD,
together with the associated preferred stock purchase right (such common stock,
together with such rights, the "ISD Common Stock"), (other than certain shares
to be cancelled pursuant to the Merger Agreement and shares held by shareholders
who properly exercise dissenters' rights ("Dissenting Shares")) will be
converted into the right to receive $7.50 in cash (the "Cash Consideration").
The "Holders of ISD Common Stock" shall include all holders of ISD Common Stock
except for Parent, Purchaser, any affiliates of Parent or Purchaser and any
holders of Dissenting Shares. The terms and conditions of the Merger are set out
more fully in the Merger Agreement.

For purposes of this opinion we have, among other things, (i) reviewed
certain financial information relating to ISD furnished to us by ISD, including
certain internal financial analyses, forecasts and projections for ISD prepared
by the management of ISD; (ii) reviewed certain publicly available information
relating to ISD; (iii) held discussions with the management of ISD concerning
the businesses, past and current operations, financial condition and future
prospects of ISD; (iv) reviewed a draft dated September 9, 1998 of the Merger
Agreement (the "Draft Agreement"); (v) reviewed the share price and trading
history of the ISD Common Stock; (vi) reviewed the valuations of publicly traded
companies that we deemed comparable to ISD; (vii) compared the financial terms
of the Merger with the financial terms, to the extent publicly available, of
other transactions that we deemed relevant; and (viii) made such other studies
and inquiries, and reviewed such other data, as we deemed relevant.

In our review and analysis, and in arriving at our opinion, we have assumed
and relied upon the accuracy and completeness of all of the financial and other
information provided to us (including information furnished to us orally or
otherwise discussed with us by management of ISD) or publicly available and have
neither attempted independently to verify, nor assumed responsibility for
verifying, any of such information. We have relied upon the assurances of the
management of ISD that they are not aware of any facts that would make such
information inaccurate or misleading. Furthermore, we did not obtain or make, or
assume any responsibility for obtaining or making, any independent evaluation or
appraisal of any of the properties, assets or liabilities (contingent or
otherwise) of ISD, nor were we furnished with any such evaluation or appraisal.
With respect to the financial forecasts and projections (and the assumptions and
bases therefor) of ISD which we reviewed, upon the advice of management of ISD,
we have assumed that such forecasts and projections have been reasonably
prepared in good faith on the basis of reasonable assumptions and reflect the
best currently available estimates and judgments of the management of ISD as to
the future financial performance of ISD, and we have further assumed that such
forecasts and projections will be realized in the amounts and in the time
periods currently estimated by the management of ISD. We have assumed that the
Merger will be

B-1
<PAGE> 143

consummated upon the terms set forth in the Draft Agreement without material
alteration thereof. We have relied as to all legal matters relevant to rendering
our opinion on the advice of counsel.

This opinion is necessarily based upon market, economic and other
conditions as in effect on, and information made available to us as of, the date
hereof. You should understand that subsequent developments may affect the
conclusion expressed in this opinion and that we disclaim any undertaking or
obligation to advise you or any person of any change in any factor matter
affecting this opinion which may come or be brought to our attention after the
date of this opinion. Our opinion is limited to the fairness, from a financial
point of view as of the date hereof, to the Holders of ISD Common Stock of the
Cash Consideration. We do not express any opinion as to the value of any
employee agreement or other arrangement entered into in connection with the
Merger Agreement or the Merger. Our opinion does not address the relative merits
of the Merger and the other business strategies that the Board of Directors of
ISD has considered or may be considering, nor does it address the decision of
the Board of Directors of ISD to proceed with the Merger.

We have provided certain investment banking services to ISD from time to
time, including acting as a co-managing underwriter for ISD's initial public
offering in 1995 and as a co-managing underwriter for a follow-on offering,
which also took place in 1995. We may, from time to time, trade in the
securities of ISD for our own account and for the accounts of our customers and,
accordingly, may at any time hold a long or a short position in such securities.
We are acting as financial advisor to ISD in connection with the Merger and will
receive, and have already received, fees in connection with the rendering of
this opinion and rendering such services, a portion of which fees are due and
payable contingent upon the closing of the Merger, and ISD has agreed to
indemnify us for certain liabilities that may arise out of the rendering of this
opinion or such services.

Our opinion is rendered at the request of and for the use of the Board of
Directors of ISD. Our opinion is not intended to be and does not constitute a
recommendation to any shareholder of ISD as to whether such shareholder should
vote upon or take any other action with respect to the Merger. Our opinion may
be included in a proxy statement of ISD distributed in connection with the
Merger, provided that this opinion is reproduced in full and any description of,
or reference to, this opinion there in is in a form and substance acceptable to
us and our legal counsel. Except as provided in the previous sentence, this
opinion shall not be reproduced, summarized, described or referred to, or
furnished to any party, without our prior written consent.

Based upon and subject to the foregoing considerations, it is our opinion
that, as of the date hereof, the Cash Consideration to be received by Holders of
ISD Common Stock in the Merger is fair to such holders from a financial point of
view.

Very truly yours,

BANCBOSTON ROBERTSON STEPHENS INC.

APPENDIX C

CHAPTER 13 OF THE CALIFORNIA GENERAL CORPORATION LAW

DISSENTERS' RIGHTS

SECTION 1300. Right to Require Purchase -- "Dissenting Shares" and "Dissenting
Shareholder" Defined.

(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 list of OTC margin stocks issued by the
Board of Governors of the Federal Reserve System, 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. Demand for Purchase.

(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 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.
C-1
<PAGE> 145

(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. Endorsement of 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. Agreed Price -- Time for Payment.

(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. Dissenter's Action to Enforce Payment.

(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
C-2
<PAGE> 146

issue, the court shall determine, or shall appoint one or more impartial
appraisers to determine, the fair market value of the shares.

SECTION 1305. Appraisers' Report -- Payment -- Costs.

(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. Dissenting Shareholder's Status as Creditor.

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. Dividends Paid as Credit Against Payment.

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. Continuing Rights and Privileges of Dissenting Shareholders.

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. Termination of Dissenting Shareholder 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.

C-3
<PAGE> 147

(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 Payment 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. Exempt Shares.

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. Attacking Validity of Reorganization or Merger.

(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.

(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

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.

FOR THE COUNTY OF SANTA CLARA

JEFFREY S. ABRAHAM, individually and on behalf CASE NO. CV776731
of all persons similarly situated, CLASS ACTION
Plaintiff, COMPLAINT FOR BREACH
v. OF FIDUCIARY DUTIES
DAVID L. ANGEL, FREDERICK B. BAMBER, EUGENE J. FLATH, ALAN JURY TRIAL DEMAND
V. KING, ERIC J. OCHILTREE, FREDERICK L. ZIEBER, INFORMATION
STORAGE DEVICES, INCORPORATED, WINBOND ELECTRONICS
CORPORATION, WINBOND INTERNATIONAL CORPORATION, PEACEFUL
RIVER CORPORATION, PIGEON CREEK HOLDING COMPANY, LTD.,
WINBOND ACQUISITION CORPORATION, AND DOES 1 THROUGH 100,
INCLUSIVE,
Defendants.
</TABLE>

Plaintiff alleges the following based upon the investigation of his
counsel, which included a review of documents filed with the Securities Exchange
Commission ("SEC") by Information Storage Devices, Incorporated ("ISD"), press
releases issued by ISD and securities analyst and media reports about ISD, and
believes that, after a reasonable opportunity for discovery, substantial
evidence will exist to support the allegations set forth in this complaint.

1. Plaintiff brings this action, individually and as a class action on
behalf of all persons similarly situated who own the common stock of ISD, other
than defendants, to enjoin the consummation of the proposed $63.8 million
acquisition of ISD by Winbond Electronics Corporation. Alternatively, in the
event that the transaction is consummated, plaintiff seeks to recover damages
caused by the director defendants' breach of fiduciary duties described herein.
The proposed transaction and the acts of the director defendants constitute a
breach of their fiduciary duties to plaintiff and the class to take all
necessary and appropriate steps to obtain the maximum value realizable for the
shareholders of ISD.

10. Defendants Angel, Bamber, Flath, King, Ochiltree, and Ziebert (the
"Individual Defendants"), by reason of their corporate directorship and/or
executive positions, stand in a fiduciary position relative to ISD's
shareholders, which fiduciary relationship, at all times relevant herein,
required the Individual Defendants to exercise their best judgment and to act
prudently and in the best interests of ISD's shareholders. The Individual
Defendants are not permitted to act in their own self-interest to the detriment
of ISD shareholders.

11. Defendant Winbond Electronics Corporation is a corporation organized
under the laws of the Republic of China in Taiwan. Winbond Electronics
Corporation and certain of its wholly owned subsidiaries, defendant Winbond
International Corporation, a British Virgin Islands corporation, defendant
Peaceful River Corporation, a British Virgin Islands corporation, and defendant

(collectively "Winbond") own approximately 14% of ISD common stock. Defendant
Winbond Acquisition Corporation ("WAC"), a newly formed subsidiary of Winbond
Electronics Corporation, is a California corporation, created for the sole
purpose of facilitating the Winbond merger with ISD.

12. Each defendant herein is sued individually as a conspirator and aider
and abettor, and, in such defendant's capacity as an officer, director or
controlling stockholder of ISD, and the liability of each arises from the fact
that he or it has engaged in all or part of the unlawful acts, plans, schemes,
or transactions complained of herein.

JURISDICTION AND VENUE

13. This Court has jurisdiction over this action pursuant to sec. 410.10 of
the California Code of Civil Procedure. The violations of law complained of
herein occurred in this county. Furthermore, the amounts in controversy exceed
the jurisdictional minimum of this Court.

D-2
<PAGE> 150

14. Venue is proper in the Superior Court of the County of Santa Clara
pursuant to California Code of Civil Procedure sec.sec. 395 and 395.5.

CLASS ACTION ALLEGATIONS

15. Plaintiff brings this action individually on his own behalf and as a
class action, on behalf of all stockholders of ISD (except defendants herein,
and any person, firm, trust, corporation, or other entity related to or
affiliated with any of the defendants) and their successors in interest, who are
or will be threatened with injury arising from defendants' actions as more fully
described herein (the "Class").

16. This action is properly maintained as a class action.

17. The Class is so numerous that joinder of all members is impracticable.
As of September 15, 1998, there were 9,914,000 shares of ISD common stock
outstanding. The disposition of their claims in a class action will be of
benefit to the parties and the Court. The record holders of ISD's common stock
can be easily determined from the stock transfer journals maintained by ISD or
its agents.

18. A class action is superior to other methods for the fair and efficient
adjudication of the claims herein asserted, and no unusual difficulties are
likely to be encountered in the management of this action as a class action.

19. There is a well-defined community of interests in the questions of law
and fact affecting the members of the Class. Among the questions of law and fact
which are common to the Class and which predominate over questions affecting any
individual class member are, among other things, the following:

a. whether defendants have engaged in conduct constituting unfair
dealing and have engaged in a plan and scheme to deceive the public
stockholders of ISD and to enrich themselves at the expense of ISD's public
stockholders;

b. whether the proposed transaction is grossly unfair to the public
stockholders of ISD;

c. whether defendants have failed to disclose all material facts
relating to the proposal including the potential positive future financial
benefits which they expect to derive from ISD;

d. whether defendants have engaged and are continuing to engage in a
plan and scheme to eliminate the public stockholders of ISD through
fraudulent, deceptive, and coercive means and devices;

e. whether defendants willfully and wrongfully failed or refused to
obtain or attempt to obtain a purchaser for the assets of ISD at a higher
price than the Winbond proposal;

f. whether plaintiff and the other members of the Class would be
irreparably damaged were the transaction complained of herein consummated;

g. whether defendants have breached or aided and abetted the breach of
the fiduciary and other common law duties owed by them to plaintiff and the
members of the Class; and

h. whether plaintiff and the Class members have been damaged and what
the proper measure of damages is.

20. Plaintiff is a member of the Class and is committed to prosecuting this
action and has retained competent counsel experienced in litigation of this
nature. Plaintiff's claims are typical of the claims of the other members of the
Class and plaintiff has the same interests as the other members of the Class.
Plaintiff does not have interests antagonistic to or in conflict with those they
seek to represent. Plaintiff is an adequate representative of the Class.

21. The likelihood of individual class members prosecuting separate
individual actions is remote due to the relatively small loss suffered by each
Class member as compared to the burden and expense of prosecuting litigation of
this nature and magnitude. Absent a class action, the defendants are likely to
avoid liability for their wrongdoing, and Class members are unlikely to obtain
redress for their wrongs alleged herein. This Court is an appropriate forum for
this dispute.

<PAGE> 151

SUBSTANTIVE ALLEGATIONS

22. On or about September 14, 1998, ISD and Winbond announced that they had
reached a definitive agreement whereby Winbond would acquire ISD in a merger
transaction. Under the terms of the agreement, Winbond will acquire all the
shares of ISD that it does not currently own at a price of $7.50 per share.

23. The terms further provide that a newly-formed subsidiary of Winbond,
WAC, will merge with and into ISD, and ISD will become an indirect, wholly-owned
subsidiary of Winbond. As a result of the merger, each outstanding share of ISD
common stock that Winbond does not own will be converted into the right to
receive $7.50 in cash.

24. Defendant's intention to pursue the above transaction is in breach of
their fiduciary duties owned to ISD's stockholders to take all necessary steps
to ensure that ISD stockholders will receive the maximum value realizable for
their shares in any extraordinary transaction involving ISD.

25. The offer being advanced and the consideration offered -- $7.50 per
share of ISD common stock -- is an unfair price, does not reflect the fair value
of ISD's equity or the significant advantages to be obtained by ISD as a result
of the transaction and does not offer any control premium. ISD stock is
currently selling on the open market for essentially the same price -- $6.875
per share. The price of ISD stock, moreover, has traded above $7.50 over the
past three quarters. The offer price is also $6 million less, or $0.75 less per
share, than an earlier written offer made by the same company, Winbond, to
acquire the same stock under the same conditions. Furthermore, the intrinsic
value of the equity of ISD is materially greater than the consideration
proposed, taking into account, among other things, ISD's asset value,
liquidation value, expected growth, full extent of its future earnings
potential, expected increase in profitability, strength of its business, its
revenues, cash flow, and earnings power. For example, according to ISD's second
quarter 1998 results which were released on or about July 16, 1998, ISD had
almost $34 million in cash.

26. For the past three fiscal quarters, ISD has shown continued and steady
increases in revenue and net income. The increases were due primarily to ISD's
introduction of highly advanced digital voice processors which were responsible
for upwards of 70% of ISD's sales, and the fact that various high-technology
companies decided to incorporate ISD's voice recognition chips in their key
products.

27. For example on January 12, 1998 in a Business Wire article, ISD
announced:

Machina has integrated ISD's voice record and playback chips in five
new products.

The new Machina products were announced Thursday at the Consumer
Electronics Show in Las Vegas. The new products are: The Cardcorder 240,
the Cardcorder 480 digital voice recorders, the Chronocorder wristwatch,
and the Bullet, and the Bullet Pro pocket digital assistants. All the new
Machina products feature ISD microchips for recording and playing back
messages. Machina products are sold in numerous retail outlets including
Sharper Image, Brookstone and Hammacher Schlemmer. "Machina has used ISD's
voice record and playback chips for a number of years and have found them
to be ideal for our innovative products," said Gary Heller, executive vice
president at Machina. "ISD's superior voice quality, their ability to
record messages over 100,000 times, and the non volatility of their chips,
enabling the user to save messages even without power, lets us provide our
customers with a variety of products with record and playback features."

* * *

"The Machina products are excellent examples of the types of
applications for which ISD's record and playback integrated circuits have
been designed," said Karin Bootsma, vice president of marketing at ISD.
"With the combination of Machinas outstanding product designs and the
excellent sound quality and reliable message retention of ISD's ChipCorder
devices, these products should be well received in the market place."

28. On January 22, 1998, ISD announced its financial results for the fourth
quarter 1997. The results showed that ISD's revenues increased 49% from $9.7
million for the fourth quarter of 1996, to $14.4 million.

D-4
<PAGE> 152

29. As a result of the fourth quarter results announcement, the price of
ISD stock climbed from a close of $6.875 on January 22, 1998 to a high of $7.75
on January 23, 1998.

30. During the past six months, ISD has also announced new technological
breakthroughs that add to its intrinsic value. As an illustration, the March 30,
1998 edition of the Business Wire reported:

ISD today announced that it has signed a licensing and joint
development agreement with Conversa (Conversational Computing Corp.) to
integrate Conversa's speaker independent continuous voice recognition
technology into a new family of digital voice processors.

ISD's first series of voice recognition chips resulting from this
joint development is expected to begin sampling in the second half of 1998.

The new ISD voice recognition chips are expected to provide high
accuracy, continuous, or conversation, speaker independent capabilities.
Products integrating these new chips will not have to be trained and will
initially respond to a set of American-English commands. Additional
languages are expected to be supported at a later date. "Today, this
continuous recognition capability typically requires at least the
processing power of a Pentium(TM). ISD's goal is to develop voice
recognition products combining this type of speech recognition software
with ISD's digital processing and RISC engine, bringing the same capability
to the chip level," said Michael Geilhufe, ISD's vice president of business
development. "We believe we can achieve similar recognition performance
with these new products, while requiring significantly less processing
horsepower than a Pentium, making them ideal for communications and
consumer applications."

ISD's new family of voice recognition chips are expected to create new
market opportunities for car kits, cordless/feature phone, automotive
navigation, appliances, electronic organizers, and digital recorders.

"We view voice recognition as a key component in our mission to offer
our customers solutions for all their voice-related products This
relationship with Conversa is a major milestone in the execution of our
product strategy and strengthens ISD's position as the Voice Solutions in
Silicon(TM) company," said David Angel, ISD chairman and chief executive
officer.

"We are excited about participating in the creation of a hands-free,
eyes-free environment for user interaction with electronic devices, such as
cell phones and automotive navigation systems," says Steve Rondel, chairman
and CEO of Conversa. "Today's hazards, associated with in-car use of these
devices, have created a universal need for a better user interface. The
accuracy, efficiency and flexibility of Conversa's speech recognition
technologies unleashes a unique opportunity to rely upon the speech
interface as the sole input mechanism for these and other electronic
appliances. Our association with ISD provides an ideal non-PC venue for
speech enabling a broad cross section of consumer electronics products."

31. Similarly, the April, 1998 edition of the Miller Freeman PC reported:

Information Storage Devices (ISD) has developed the ISD4000 family,
which is ISD's first record and playback chips based on SuperFlash memory
technology.

The ISD4000 family quadruples ISD's current longest recording duration
to 16min. It consists of the ISD4002 series, offering 2 to 4min durations,
the ISD4003 series, with 4 to 8min durations, and the ISD4004 series, with
8 to 16min durations.

According to ISD, the up to 16min of record time will enable cellular
and other comms equipment manufacturers to provide a suite of advanced
voice features.

The ISD4000 family is suitable for analogue and digital cellular
phones, as well as cordless phones that rely on low voltage technology to
minimize power consumption. The ISD4000 will allow the addition of call
record, voice memo, call screening, and a built in telephone answering
device (TAD).

D-5
<PAGE> 153

The single-chip ISD4000 family can provide similar design advantages
of ISD's ChipCorder technology, with the added cost and space savings Flash
technology can provide.

In addition to TSOP, SOIC and PDIP packaging options, the ISD4000
family will also be available in near die size MicroBGA chip scale
packaging, which helps reduce the package footprint.

The ISD4000 family is also pin for pin compatible with the existing
ISD33000 series.

ISD's multi-level storage technology provides improved sound quality
with, says ISD, an eight to one audio storage efficiency improvement over
digital approaches.

While ISD's non-volatile technology has always enabled Chip-Corder
circuits to retain information without power, the 3V, ISD4000 family is
said to have less battery drain than alternative DSP solutions.

32. The introduction of new products that are able to gain market
acceptance has enabled ISD to improve its financial results. On April 16, 1998,
ISD announced its results for the first quarter 1998:

ISD announced today that revenue for the first quarter ended April 4,
1998 increased 47% to $12.2 million from $8.3 million for the first quarter
of 1997. The net loss for the period was $1.2 million, or $0.12 per share.
The net loss for last year's first quarter was $5.4 million, or $0.56 per
share, which included the write-off of in-process research and development
of $4.0 million before taxes associated with the acquisition of the
CompactSPEECH product line.

"First quarter shipments of ISD's 33000 ChipCorder voice record and
playback products were roughly 30% ahead of the fourth quarter and more
than three times higher than last year's first quarter. Our new Sidewinder
series, in its first full quarter of production, also contributed to the
growth. All told, products introduced in the past year and a half accounted
for nearly 70% of first quarter sales. The Company's performance would have
been stronger but for order postponements announced on March 13, 1998 that
reduced revenue by an estimated $3 million from where it otherwise would
have been. We have taken steps to better align costs with current demand
conditions, including a reduction in force," said Chairman and Chief
Executive Officer David L. Angel.

33. On June 29, 1998 over the Business Wire, ISD announced that Motorola
had agreed to integrate ISD components into new Motorola products:

ISD announced today that Motorola has integrated ISD's voice record
and playback chips into Motorola's new cd900 family of Dual Band GSM
digital cellular phones. The dual band cd900 phones operate on both GSM 900
and GSM 1800 systems. Motorola's cd920 and cd930 both contain the
VoiceNote(TM) memo recorder which allows up to three minutes of message
recording for storing memos or recording phone calls. VoiceNote is enabled
by the ISD33180 chip, a member of the ISD33000 series, the industry's first
family of 3-volt, single-chip record and playback products optimized for
communication devices.

Motorola's new GSM digital cellular phones are the third and fourth
Motorola cellular phones to integrate ISD's voice chips for voice storage
functions. Motorola first integrated the ISD voice chips into their
Micro-TAC Elite(TM) cellular phone, providing a built-in answering machine
function. ISD's voice chips can also be found in Motorola's top-of-the-line
StarTAC 8600 cellular phone, providing up to four minutes of record time,
for recording memos, for use as an on-board answering machine, and for
recording phone calls "on-the-fly." This provides added safety for users
needing to record directions, phone numbers and other important information
while driving.

"The proliferation of ISD-enabled voice features throughout Motorola's
cellular product lines and next generation platforms demonstrates the value
Motorola believes these features bring to their customers," said David
Angel, ISD's chairman and chief executive officer. "We anticipate that over
the next few years, these types of voice features in cellular phones will
become standard throughout the cellular industry."

"VoiceNote is an indispensable business feature in our new cd900
family of phones. The VoiceNote feature lets us provide our customers with
the highest quality of sound reproduction, for storing memos or
D-6
<PAGE> 154

recording phone calls, available on the market today," said Ralph Pini,
senior vice president and general manager of Motorola's Cellular Subscriber
Group, Europe, Middle East & Africa. "The use of the ISD voice chip in
VoiceNote, with our other advanced features, makes the cd900 family the
ultimate business phones."

34. On July 16, 1998, ISD announced its financial results for the second
quarter 1998:

ISD Friday announced that net income for the second quarter ended June
30, 1998 was $10,000 or 0 cents per share, on revenue of $12.2 million.
This compares with a net loss of $910,000, or 9 cents per share, on revenue
of $11.4 million for the second quarter of 1997.

* * *

Chairman and Chief Executive Officer David L. Angel attributed the
gain in second quarter earnings to higher gross margin, primarily the
result of improved manufacturing yields, particularly on new products, as
well as to the force reduction announced in April and stringent control
over variable costs.

Angel said that products introduced within the past year accounted for
more than 70 percent of second quarter sales. "ISD's first voice record and
playback products based on flash technology -- 4 and 8 minute versions of
the ISD4000 family -- recently were qualified and released to favorable
reviews by our customers. We expect to enjoy additional cost reductions as
flash technology ramps up to full volume production."

Angel continued, "We believe that we have added considerable value to
ISD in the past year. We now offer voice record and playback products
featuring advanced flash technology. We have the latest DSP voice products
and the broadest palette of easy-to-implement solutions in the voice
industry. And we've brought speech recognition into the mix for the first
time through our licensing and joint development agreement with Conversa.

We recently demonstrated a prototype speaker independent, continuous
voice recognition product to a few cellular, automotive and industrial
companies in North America and Europe. The market appears to be moving in
our direction, as voice features are becoming increasingly ubiquitous in
products ranging from cell phones to computers to automobiles. We remain
optimistic about the future of ISD."

35. The positive news of ISD's financial prospects resulted in two written
offers to purchase the outstanding shares of ISD stock. As was reported on July
24, 1998 over the Business Wire:

ISD Friday announced that it has received a written offer from Winbond
Int'l. Corp., an existing shareholder of the company, to acquire ISD
through a cash merger in which Winbond would acquire all currently
outstanding ISD shares that Winbond does not now own, for $8.25 per share.

Winbond's proposal is non-binding and is subject to a number of
material conditions, including the execution of definitive agreements,
completion of satisfactory due diligence, waiver of ISD's shareholder
rights plan, board approval by both companies, ISD shareholder approval,
and compliance with other customary legal requirements.

Winbond has asked for a response from ISD by July 31, 1998. ISD has
not yet responded to this proposal. The board of ISD will be considering
this proposal, along with another non-binding cash acquisition proposal
recently received by ISD from another party, which other proposal expires
at the end of July 24, 1998 by its terms, and other strategic alternatives,
with its investment bankers.

36. On August 3, 1998, ISD announced over the Business Wire that it had
entered into an exclusive agreement with Conversational Computing Corporation:

Conversa (Conversational Computing Corp.) announced that ISD, with
headquarters in San Jose, Calif., has made a multimillion dollar equity
investment in Conversa intended to strengthen the partnership between the
two companies. The investment underscores the mutual commitment of both
firms to develop new and highly competitive embedded speech products that
will be applied to a variety of

D-7
<PAGE> 155

electronic devices. As a component of the commitment, Conversa has agreed
to provide ISD with exclusive worldwide licensing rights to embed
Conversa's speaker-independent, continuous-speech recognition technology in
ISD's unique "voice-solutions" semiconductor applications. In turn, ISD has
agreed that Conversa will be its exclusive provider of available speech
technologies. The agreement also provides for future access to enhancements
of the Conversa software. The licensing agreement and investment are an
expansion of the joint development agreement Conversa signed with ISD last
March to integrate Conversa's speaker-independent continuous-speech
recognition technology into a new family of ISD digital voice processors.
ISD's first series of voice recognition chips resulting from this joint
development is expected to begin sampling in the fourth quarter of 1998.
"The marriage of our speaker-independent continuous-speech recognition
technology and ISD's flexible chip architectures provides an ideal non-PC
venue for speech. It will extend a potential communications link beyond the
PC and the Internet to a broad cross-section of consumer electronics
devices," said Steve Rondel, chairman and chief executive officer of
Conversa. "This licensing agreement allows our speech recognition software
to be embedded in a very broad range of components and applications,"
Rondel added. The new ISD voice recognition chips are expected to provide
accurate, continuous, or conversational, speaker-independent capabilities,
including full-continuous digit recognition functionality. Products
integrating these new chips will not have to be trained and will respond to
a set of American-English commands. Additional languages are expected to be
supported at a later date. ISD's new family of voice recognition chips are
expected to create new market opportunities for a myriad of products,
including car kits, cordless/feature phones, automotive navigation,
appliances, electronic organizers and digital recorders.

37. Finally, on September 1, 1998, ISD announced over the Business Wire
that its ISD4004 product was available to the market:

ISD today announced the availability of the ISD4004, the industry's
first and only single chip solution with a record and playback duration of
up to 16 minutes. The ISD4004 is part of the ISD4000 ChipCorder(R) family,
ISD's first record and playback chips based on SuperFlash(R) memory
technology. Other members of the ISD4000 family include the ISD4002 series,
offering two-to four-minute durations and the ISD4003 series, with four-to
eight-minute durations.

"Our new quarter-hour duration chips extend the possibilities for
immediate development of a host of new products, including automotive
communication devices, cellular telephones, "single chip" telephone
answering devices, cordless phones, tapeless recorders and dictation
devices, and personal digital assistants (PDAs), where unparalleled sound
quality is desired," said Karin Bootsma, vice president of marketing at
ISD. "Our single chip implementation replaces the multiple chips and
extensive software programming that was previously required. We are working
with a number of automotive manufacturers, for example, on voice-integrated
traffic telematic systems, who have expressed the desire for longer
duration recording times with the high quality sound and ease of use
demonstrated by ISD products."

While the 16 minute ISD4004 is ideally suited for stand alone or
integrated telephone answering devices and automotive applications, the
ISD4000 family has been optimized for cellular phones. The ISD4000 family
enables cell phone manufacturers to add such features as cell record, voice
memo, call screening, and a built-in telephone answering device (TAD).

- - -

The single-chip flash-based ISD4000 family offers all the design
advantages of ChipCorder(R) technology with the added cost and space
savings flash technology provides. Every product in the family offers a
complete, easy to integrate solution with minimal software development. In
addition to TSOP, SOIC, and PDIP packaging options, the ISD4002 and ISD4003
will be available in near die size MicroBGA(TM) Chip Scale Packaging which
greatly reduces the package footprint.

enabled ChipCorder circuits to retain information without power, the new
3-volt ISD4000 family has significantly less battery drain than alternative
DSP solutions. The ISD4000 series chips typically consume 30 milliamps of
operating current while DSP solutions typically require 200 to 300
milliamps of operating current. ISD developed the ISD4000 family based on
licensed SuperFlash technology from SST (Silicon Storage Technology, Inc.).
Prior to flash technology, ISD used, and continues to use, EEPROM
multilevel storage technology in the ChipCorder voice circuits for up to
four minutes of voice record and playback time. By taking advantage of
SuperFlash technology, ISD expects to continue to provide customers with a
wider variety of recording lengths, as well as to allow them to benefit
from the cost savings flash technology offers.

38. The upward trend in ISD's financial results, its technological
advances, and the competing offer to acquire ISD notwithstanding on September
11, 1998, ISD and Winbond signed an agreement and Plan of Merger providing for
the acquisition of ISD by WAC. The Individual Defendants agreed to accept
Winbond's offer price of $7.50 per share, an amount significantly less than the
original offer price of $8.25 per share.

39. The Individual Defendants have considerably more knowledge and economic
power compared to that of the investing public because they control the business
and corporate affairs of ISD, and they are in possession of material, non-public
information concerning ISD's assets, businesses, and future prospects. This
disparity makes it inherently unfair for the Individual Defendants to transfer
the ownership of ISD from its public stockholders at this time and at such an
unfair and grossly inadequate price.

40. The proposed transaction is not the result of arm's-length
negotiations, but was fixed arbitrarily by ISD and agreed to by defendants as
part of the unlawful plan and scheme to obtain the entire ownership of ISD at
the lowest possible price. These facts have not been disclosed by defendants.

41. Furthermore, the Individual Defendants' willingness to entertain the
proposed lower offer requires them to take all reasonable steps to assure the
maximization of stockholder value, including the implementation of a bidding
mechanism to foster a fair auction of ISD to the highest bidder or the
exploration of strategic alternatives which will return greater or equivalent
short-term value to the plaintiff and the Class.

42. There is no indication that the Individual Defendants have taken any
steps to ensure that ISD's stockholders' interest in maximizing the value of
their holdings were protected by conducting an auction for ISD or otherwise
seeking out other potential purchasers or the highest possible bid for ISD, or
exploring strategic alternatives which will obtain the highest possible price
for ISD's stockholders or return greater or equivalent short-term value to the
plaintiff and the Class. If the transaction is consummated, ISD shareholders
will be deprived of the opportunity for substantial gains which ISD may realize.

43. By the acts, transactions, and courses of conduct alleged herein,
defendants, individually and as part of a common plan and scheme and/or aiding
and abetting one another in total disregard of their fiduciary duties, are
attempting to deceive plaintiff and the Class and deprive them unfairly of their
investment in ISD.

44. The proposed transaction is wrongful, unfair, and harmful to ISD's
public stockholders, and represents an attempt by defendants to aggregate their
personal and financial positions and interests and to enrich themselves, at the
expense of and to the detriment of the ISD's public stockholders. The proposed
transaction will deny Class members their right to share proportionately in the
true value of ISD's assets, profitable business, and future growth in profits
and earnings, while usurping the same for the benefit of ISD at an unfair and
inadequate price.

45. The Individual Defendants stand to profit the most from the proposed
takeover of ISD by Winbond. As a group, the Individual Defendants hold over 10%
of all shares of ISD's common stock.

46. By reason of all of the foregoing, defendants herein have willfully
participated in unfair dealing toward plaintiff and the other members of the
Class and have engaged in and substantially assisted and aided and abetted each
other in breach of the fiduciary duties owed by them to the Class.

47. Winbond and WAC have knowingly aided and abetted the breaches of
fiduciary duty committed by the Individual Defendants. Through a joining venture
between ISD and Winbond, Winbond and WAC are

D-9
<PAGE> 157

privy to ISD's proprietary, non-public technological and market information
which Winbond and WAC are now able to use to their advantage at the expense and
to the detriment of ISD's public shareholders. Through the proposed merger,
Winbond and WAC will be able to pursue their own interests in the venture, while
excluding ISD's shareholders from sharing in future benefits therefrom.

48. Defendants have violated fiduciary and other common law duties owed to
the plaintiff and the other members of the Class in that they have not and are
not exercising independent business judgment and have acted and are acting to
the detriment of the Class in order to benefit themselves and/or their
colleagues.

49. As a result of the actions of defendants, plaintiff and the Class have
been and will be damaged in that they have been deceived, are the victims of
unfair dealing, and are not receiving the fair value of ISD's assets and
businesses.

50. Unless enjoined by this Court, defendants will continue to breach their
fiduciary duties owed to plaintiff and the Class and will succeed in their plan
to enrich themselves by excluding the Class from its fair proportionate share of
ISD's assets and businesses, all to the irreparable harm of the Class.

51. Plaintiff and the Class have no adequate remedy of law.

FIRST CAUSE OF ACTION
(AGAINST ALL DEFENDANTS
FOR BREACH OF FIDUCIARY DUTY)

52. Plaintiff hereby incorporates by reference paragraphs 1 through 51
above as though fully set forth herein.

53. By virtue of plaintiff's purchase of ISD's common stock, and the
Individual Defendants' positions of management and control, and because
plaintiff reposed trust and confidence in them, the individual defendants owed
to plaintiff a fiduciary duty of the highest good faith, integrity and fair
dealing.

54. In doing the things heretofore alleged, ISD and the Individual
Defendants violated their fiduciary obligations to plaintiff.

55. As a proximate result of defendants' aforesaid conduct, plaintiff was
damaged by injury to his property, lost profits, loss of future income, and
other general and specific damages.

WHEREFORE, plaintiff prays for judgment and relief as follows:

(1) declaring that this lawsuit is properly maintainable as a class
action and certifying plaintiff as representative of the Class;

(2) declaring that the defendants and each of them have committed or
aided and abetted a gross abuse of trust and have breached their fiduciary
duties to plaintiff and the other members of the Class;

(3) declaring the transaction null and void;

(4) preliminarily and permanently enjoining defendants and all persons
acting under, in concert with, or for them, from proceeding with,
consummating, or closing the transaction;

(5) in the event the transaction is consummated, rescinding it and
setting it aside;

(6) ordering defendants, jointly and severally, to account to
plaintiff and the Class for all profits realized and to be realized by them
as a result of the transaction complained of and, pending such accounting,
to hold such profits in a constructive trust for the benefit of plaintiff
and other members of the Class;

(7) ordering defendants to establish a stockholders' committee
comprised of Class members and their representatives to ensure fair and
adequate procedural safe-guards that allow independent input by plaintiff
and the Class in connection with any transaction for the shares of ISD;

D-10
<PAGE> 158

(8) awarding compensatory damages against defendants, jointly and
severally, in the amount to be determined at trial, together with
prejudgement interest at the maximum rate allowable by law;

(9) awarding plaintiff and the Class their costs and disbursements and
reasonable allowances for plaintiff's attorneys' and experts' fees and
expenses; and

(10) granting such other and further relief as may be just and proper.
