                         AGREEMENT AND PLAN OF MERGER


          AGREEMENT AND PLAN OF MERGER (this "Agreement"), dated as of January
20, 1999, by and between ICS Merger Corp., a Pennsylvania corporation ("ICS"),
and Integrated Circuit Systems, Inc., a Pennsylvania corporation (the
"Company").

          WHEREAS, the respective Boards of Directors of ICS and the Company
have approved the merger of ICS with and into the Company, as set forth below
(the "Merger"), in accordance with the Business Corporation Law of the
Commonwealth of Pennsylvania (the "BCL") and upon the terms and subject to the
conditions set forth in this Agreement, holders of shares of common stock, no
par value, of the Company (the "Common Shares") issued and outstanding
immediately prior to the Effective Time (as defined below) will be entitled,
subject to the terms hereof and other than as set forth herein, the right to
receive cash in this Agreement or, in the case of certain specifically
designated holders of Common Shares, the right to receive shares of common stock
of the Surviving Corporation (as defined below) (the "Rollover Shares");

          WHEREAS, the Board of Directors of the Company (the "Company Board")
has, in light of and subject to the terms and conditions set forth herein, (i)
determined that (A) the consideration to be paid for each Common Share (except
for Rollover Shares) in the Merger (as hereinafter defined) is fair to the
shareholders of the Company, and (B) the Merger is otherwise in the best
interests of the Company and its shareholders, and (ii) resolved to approve and
adopt this Agreement and the transactions contemplated hereby and to recommend
approval and adoption by the shareholders of the Company of this Agreement;

          WHEREAS, the Merger requires the vote of a majority of the votes cast
by all of the issued and outstanding Common Shares entitled to vote for the
approval thereof (the "Company Shareholder Approval");

          WHEREAS, ICS and the Company desire to make certain representations,
warranties, covenants and agreements in connection with the Merger, and also to
prescribe various conditions to the Merger; and

          NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein, ICS and
the Company agree as follows:

                                   ARTICLE 1

          Section 1.2    Closing and Effective Time.  The closing of the Merger
(the "Closing") will take place at 10:00 a.m., local time, on the fifth business

with applicable law is referred to herein as the "Effective Time."

          Section 1.3    Effects of the Merger.  The Merger shall have the
effects set forth in the BCL.  Without limiting the generality of the foregoing,
and subject thereto, at the Effective Time, all the properties, rights,
privileges, powers and franchises of the Company and ICS shall vest in the
Surviving Corporation, and all debts, liabilities and duties of the Company and
ICS shall become the debts, liabilities and duties of the Surviving Corporation.

           Section 1.4   Articles of Incorporation and By-Laws of the Surviving
Corporation.

                (a) The Articles of Incorporation, as amended, of the Company,

provide for the number and types of shares of capital stock designated on the
Rollover Schedule (as hereinafter defined), shall be the Articles of
Incorporation of the Surviving Corporation until thereafter amended in
accordance with the provisions thereof and hereof and applicable law.

                (b) The By-Laws of the Company in effect at the Effective Time
shall be the By-Laws of the Surviving Corporation until amended, subject to the
provisions of Section 5.7 of this Agreement, in accordance with the provisions
thereof and applicable law.

          Section 1.5    Directors.  Subject to applicable law, the directors of

                                   ARTICLE 2
            EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE COMPANY

          Section 2.1    Effect on Capital Stock.  As of the Effective Time, by
virtue of the Merger and without any action on the part of the holders of any
Common Shares or any shares of capital stock of ICS:

                (a) Merger Consideration.  The Merger Consideration shall be
equal to $21.25 per share (the "Merger Consideration").

                (b) Conversion of Shares.

                          (i) Each issued and outstanding Common Share (except
for (x) Dissenting Shares (as defined herein) and (y) those Common Shares held
by those holders of record listed in the Rollover Schedule, but only up to the
aggregate levels indicated in such Rollover Schedule (the "Rollover Shares"))
shall, by virtue of the Merger and without any action on the part of the holder
thereof, be converted into the right to receive from ICS the Merger
Consideration without interest upon surrender of the certificate formerly
representing such Common Share in the manner provided in, and otherwise in
accordance with, Section 2.3 hereof. All such Common Shares, when so converted,
shall no longer be outstanding and shall automatically be canceled and retired
and shall cease to exist, and each holder of a certificate representing any such
Common Shares shall cease to have any rights with respect thereto, except the
right to receive the Merger Consideration therefor upon the surrender of such
certificate in the manner provided in, and in accordance with, Section 2.3
hereof.

                          (ii) At the Effective Time, (i) each Rollover Share
and (ii) each share of common stock, par value $.01 per share, of ICS issued and
outstanding immediately prior to the Effective Time shall, by virtue of the
Merger and without any action on the part of the holder thereof, be converted
into and become such number and type of shares of the Surviving Corporation as
shall be designated on a schedule (the "Rollover Schedule") to be provided by
ICS to the Company and consented to in writing by each shareholder listed
thereon as to such shareholder's shares, prior to February 10, 1999.

                (c) Cancellation of Treasury Stock. Each Common Share that is
owned by the Company or by any wholly owned subsidiary of the Company shall
automatically be canceled and retired and shall cease to exist, and no cash or
other consideration shall be delivered or deliverable in exchange therefor.

                (d) Dissenting Shares. Common Shares issued and outstanding
immediately prior to the Effective Time and held by a holder who has not voted
in favor of the Merger or consented thereto in writing and who has demanded
payment of the fair value for such holder's Common Shares as determined by
appraisal for such Common Shares in accordance with the BCL prior to the
Effective Time ("Dissenting Shares") shall not be converted into, or be
exchangeable for, a right to receive the Merger Consideration, unless and until
such holder shall have failed to perfect or shall have withdrawn or otherwise
lost such holder's right to appraisal. If after 

                                      -3-
<PAGE>
 
the Effective Time such holder shall have failed to perfect or shall have
withdrawn or lost such holder's right to appraisal, such Common Shares shall be
treated as if they had been converted as of the Effective Time into a right to
receive the Merger Consideration. The Company shall give ICS prompt notice of
any demands received by the Company for appraisal of Common Shares, and ICS
shall have the right to participate in all negotiations and proceedings with
respect to such demands. The Company shall not, except with the prior written
consent of ICS, make any payment with respect to, or settle or offer to settle,
any such demands.

          Section 2.2    Options; Stock Plans.  Immediately prior to the
Effective Time, each holder of a then-outstanding employee stock option, whether
or not fully exercisable, to purchase Common Shares (an "Option")  granted under
the Company's 1991 and 1992 Stock Option Plan and 1997 Equity Compensation Plan
(the "Stock Plans") will be entitled to receive in settlement of such Option a
cash payment from the Company equal to the product of (i) the total number of
Common Shares previously subject to such Option and (ii) the excess of the
Merger Consideration over the exercise price per Common Share subject to such
Option, subject to any required withholding of taxes.  If necessary or
appropriate, the Company will, upon the request of ICS, use reasonable efforts
to obtain the written acknowledgment of each employee holding an Option that the
payment of the amount of cash referred to above will satisfy in full the
Company's obligation to such employee pursuant to such Option and take such
other action as is necessary to effect the provisions of this Section 2.2.  The
amounts payable pursuant to this Section 2.2 shall be paid as soon as reasonably
practicable following the Closing Date and shall be subject to and made net of
all applicable withholding taxes.  The Company will solicit from each Retained
Employee, as such term is defined in that certain asset purchase agreement among
3COM Corporation, the Company and ICS Technologies, Inc., an agreement by each
such employee who owns an Option (as defined in such agreement) to accept, in
lieu of stock upon the exercise of the Option, the amount of cash such employee
would have received if they received the cash payments described in this Section
2.2 (the "Option Payment") which shall be a condition to any agreement by the
Company to pay such Option Payment in respect of such Options.

           Section 2.3   Payment for Common Shares.

                (a) Prior to the Effective Time, ICS and the Company shall
designate the Company's registrar and transfer agent or such other bank or trust
company as may be approved by ICS and the Company Board, to act as exchange
agent for the holders of Common Shares in connection with the Merger, pursuant
to an agreement providing for the matters set forth in this Section 2.3 and such
other matters as may be appropriate and the terms of which shall be reasonably
satisfactory to the Company and ICS (the "Exchange Agent"), to receive the funds
to which holders of Common Shares shall become entitled pursuant to Section
2.1(b) hereof. At the Effective Time, ICS shall deposit, or ICS shall otherwise
take all steps necessary to cause to be deposited, in trust with the Exchange
Agent in an account for the benefit of holders of Common Shares (the "Exchange
Fund") the aggregate Merger Consideration to which holders of Common Shares
shall be entitled at the Effective Time pursuant to Section 2.1(b) hereof.

                (b) Promptly after the Effective Time, and in any event not
later than three business days following the Effective Time, ICS shall cause the
Exchange Agent to mail to each 

                                      -4-
<PAGE>
 
record holder of certificates (the "Certificates") that immediately prior to the
Effective Time represented Common Shares a form of letter of transmittal which
shall specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon proper delivery of the Certificates or an
Affidavit of Loss in Lieu of Lost Certificate (as defined below) to the Exchange
Agent and instructions for use in surrendering such Certificates and receiving
the Merger Consideration in respect thereof.

                (c) In effecting the payment of the Merger Consideration in
respect of Common Shares represented by Certificates entitled to payment of the
Merger Consideration pursuant to Section 2.1(b) hereof, upon the surrender of
each such Certificate, together with a letter of transmittal duly executed, the
Exchange Agent shall promptly, and in any event not later than three business
days following receipt of such Certificates and letter of transmittal, pay the
holder of such Certificate the Merger Consideration multiplied by the number of
Common Shares represented by such Certificate, in consideration therefor. Upon
such payment such Certificate shall forthwith be canceled.

                (d) Until surrendered in accordance with paragraph (c) above,
each such Certificate (other than Certificates representing Common Shares held
by ICS or any of its affiliates, in the treasury of the Company or by any wholly
owned subsidiary of the Company or Dissenting Shares or Rollover Shares) shall
represent solely the right to receive the aggregate Merger Consideration
relating thereto. No interest or dividends shall be paid or accrued on the
Merger Consideration. If the Merger Consideration (or any portion thereof) is to
be delivered to any person other than the person in whose name the Certificate
formerly representing Common Shares surrendered therefor is registered, it shall
be a condition to such right to receive such Merger Consideration that the
Certificate so surrendered shall be properly endorsed or otherwise be in proper
form for transfer and that the person surrendering such Common Shares shall pay
to the Exchange Agent any transfer or other taxes required by reason of the
payment of the Merger Consideration to a person other than the registered holder
of the Certificate surrendered, or shall establish to the satisfaction of the
Exchange Agent that such tax has been paid or is not applicable.

                (e) In the event any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the Person (who shall
be the record owner of such Certificate) claiming such Certificate to be lost,
stolen or destroyed (an "Affidavit of Loss in Lieu of Lost Certificate"), the
Exchange Agent will issue in exchange for such lost, stolen or destroyed
Certificate the Merger Consideration deliverable in respect thereof, provided
that the Person to whom the Merger Consideration is paid shall, as a condition
precedent to the payment thereof, give the Surviving Corporation a bond in such
sum as it may direct or otherwise indemnify the Surviving Corporation in a
manner satisfactory to it against any claim that may be made against the
Surviving Corporation with respect to the Certificate claimed to have been lost,
stolen or destroyed.

                (f) No dividends or other distributions with respect to Common
Shares with a record date after the Effective Time shall be paid to the holder
of any unsurrendered Certificate with respect to the Common Shares represented
thereby until the surrender of such Certificates or delivery of an Affidavit of
Loss in Lieu of Lost Certificate in accordance with this Section 2.3.

                                      -5-
<PAGE>
 
                (g) Promptly following the date which is 180 days after the
Effective Time, the Exchange Agent shall deliver to the Surviving Corporation
all cash, Certificates and other documents in its possession relating to the
transactions described in this Agreement, and the Exchange Agent's duties shall
terminate. Thereafter, each holder of a Certificate formerly representing a
Common Share may surrender such Certificate to the Surviving Corporation and
(subject to applicable abandoned property, escheat and similar laws) receive in
consideration therefor the aggregate Merger Consideration relating thereto,
without any interest or dividends thereon.

                (h) After the Effective Time, there shall be no transfers on the
stock transfer books of the Surviving Corporation of any Common Shares which
were outstanding immediately prior to the Effective Time. If, after the
Effective Time, Certificates formerly representing Common Shares (other than the
Rollover Shares) are presented to the Surviving Corporation or the Exchange
Agent, they shall be surrendered and canceled in return for the payment of the
aggregate Merger Consideration relating thereto, as provided in this Article 2.

                (i) None of ICS, the Company or Exchange Agent shall be liable
to any person in respect of any cash from the Exchange Fund delivered to a
public official pursuant to any applicable abandoned property, escheat or
similar law. If any Certificates shall not have been surrendered prior to seven
years after the Effective Time, any such shares, 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.

                                   ARTICLE 3
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

          The Company represents and warrants to ICS as follows:

          Section 3.1    Organization and Qualification; Subsidiaries.  The
Company and each of its Subsidiaries (as hereinafter defined) is a corporation
duly organized, validly existing and in good standing under the laws of its
state or jurisdiction of incorporation and has all requisite corporate power and
corporate authority to own, lease and operate its properties and to carry on its
business as now being conducted and is in good standing as a foreign corporation
in each jurisdiction where the properties owned, leased or operated, or the
business conducted, by it require such qualification and where failure to be in
good standing or to so qualify would have a Material Adverse Effect on the
Company.  The term "Material Adverse Effect on the Company," as used in this
Agreement, means any effect, event, occurrence, change or state of facts that,
or aggregated with other effects, events, occurrences, changes or states of
facts, is, or is reasonably likely to be, materially adverse to (i) the assets,
liabilities, business, property, operations, condition as a whole (financial or
otherwise) of the Company and its Subsidiaries taken as a whole, or (ii) the
ability of the Company and its Subsidiaries to perform in all material respects
their obligations under this Agreement.  The Company has heretofore made
available to ICS a complete and correct copy of its Articles of Incorporation,
as amended, and By-Laws.  Set forth on Section 3.1 of the Disclosure Schedule is
a list of every corporation, limited liability company, partnership or other
business organization or entity of which the Company owns either directly or
through its Subsidiaries, (a) 

                                      -6-
<PAGE>
 
more than 50% of (i) the total combined voting power of all classes of voting
securities of such entity, (ii) the total combined equity interests therein, or
(iii) the capital or profit interests therein, in the case of a partnership; or
(b) or otherwise has the power to vote or direct the voting of sufficient
securities to elect a majority of the board of directors or similar governing
body of such entity (the "Subsidiaries").

          Section 3.2    Capitalization; Subsidiaries.  The authorized capital
stock of the Company consists of 50,000,000 Common Shares and 5,000,000 shares
of preferred stock, no par value ("Preferred Stock").  As of the close of
business on January 19, 1999, 12,298,425 Common Shares were issued and
outstanding (which includes certain treasury shares), all of which are entitled
to vote on this Agreement except for those shares held in treasury.  The Company
has no shares of Preferred Stock issued and outstanding.  As of January 18,
1999, except for (i) 2,396,646 Common Shares reserved for issuance pursuant to
outstanding Options and rights granted under the Stock Plans, there are not now,
and at the Effective Time there will not be, any existing options, warrants,
calls, subscriptions, or other rights, or other agreements or commitments,
obligating the Company to issue, transfer or sell any shares of capital stock of
the Company or any of its Subsidiaries. Section 3.2 of the Disclosure Schedule
sets forth the name of each holder of an outstanding Option under the Stock
Plans, and with respect to each Option held by any such holder, the grant date,
vesting schedule, exercise price and number of Common Shares for which such
Option is exercisable.  All issued and outstanding Common Shares are, and all
Common shares which may be issued pursuant to the exercise of outstanding
Options will be, when issued in accordance with the respective terms thereof,
validly issued, fully paid, nonassessable and free of preemptive rights. All of
the outstanding shares of capital stock of each of the Company's Subsidiaries
have been validly issued and are fully paid and non-assessable and, except as
set forth on Section 3.2 of the Disclosure Schedule, are owned by either the
Company or another of its Subsidiaries free and clear of all liens, charges,
claims or encumbrances.  There are no outstanding options, warrants, calls,
subscriptions, or other rights, or other agreements or commitments, obligating
any Subsidiary of the Company to issue, transfer or sell any shares of its
capital stock.

           Section 3.3   Authority Relative to this Agreement.

                (a) The Company has all necessary corporate power and authority
to execute and deliver this Agreement and, except for the approval of this
Agreement by the shareholders of the Company, to consummate the transactions
contemplated hereby. The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby have been duly and validly
authorized by the Company Board and no other corporate proceedings on the part
of the Company or on the part of the shareholders of the Company are necessary
to authorize this Agreement or to consummate the transactions so contemplated,
other than the approval of this Agreement by the holders of a majority of the
outstanding Common Shares of the Company. This Agreement has been duly and
validly executed and delivered by the Company, and, assuming this agreement
constitutes a valid and binding obligation of ICS, this Agreement constitutes a
valid and binding agreement of the Company, enforceable against the Company in
accordance with its terms, except as may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium, fraudulent conveyance or other similar
laws affecting the rights of creditors generally, general 

                                      -7-
<PAGE>
 
equitable principles (whether considered in a proceeding in equity or at law)
and an implied covenant of good faith and fair dealing.

                (b) Except as set forth in Section 3.3 of the Disclosure
Schedule, the execution and delivery of this Agreement does not, and the
consummation of the transactions contemplated by this Agreement and compliance
with the provisions of this Agreement will not, conflict with, or result in any
violation of, or default (with or without notice or lapse of time, or both)
under, or give rise to a right of consent, termination, purchase, cancellation
or acceleration of any obligation or to loss of any property, rights or benefits
under, result in the imposition of any additional obligation under, or result in
the creation of any Lien (as defined herein) upon any of the properties or
assets of the Company or any of its Subsidiaries under or constitute a "change
of control" under, require the consent from, or the giving of notice to, a third
party pursuant to (i) the organizational documents of the Company or any of its
Subsidiaries, (ii) any contract, instrument, permit, concession, franchise,
license, loan or credit agreement, note, bond, mortgage, indenture, lease or
other property agreement, partnership or joint venture agreement or other
legally binding agreement or obligation, whether oral or written (a "Contract"),
applicable to the Company or any of its Subsidiaries or their respective
properties or assets or (iii) subject to the governmental filings and other
matters referred to in the following paragraph, any judgment, order, decree,
statute, law, ordinance, rule or regulation applicable to the Company or any of
its Subsidiaries or their respective properties or assets, other than, in the
case of clauses (ii) and (iii), any such conflicts, violations, defaults,
rights, Liens, adverse consequences resulting from such change of control or
where the failure to obtain such consents or provide such notices that,
individually or in the aggregate, would not have a Material Adverse Effect on
the Company. For purposes of this Agreement, "Lien" shall mean, with respect to
any asset, any imperfection of title, lien, lease, pledge, encumbrance,
mortgage, claim, option, voting trust, preemptive right, attachment,
encroachment or other charge or security interest in or on such asset.

                (c) Other than in connection with, or in compliance with, the
provisions of the BCL with respect to the transactions contemplated hereby, the
Securities Exchange Act of 1934 (the "Exchange Act"), the securities laws of the
various states and the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended (the "HSR Act"), no authorization, consent or approval of, or filing
with, any Governmental Entity (as hereinafter defined) is necessary for the
consummation by the Company of the transactions contemplated by this Agreement
other than authorizations, consents and approvals the failure to obtain, or
filings the failure to make, which would not, in the aggregate, have a Material
Adverse Effect on the Company.  As used in this Agreement, the term
"Governmental Entity" means any government or subdivision thereof, domestic,
foreign or supranational or any administrative, governmental or regulatory
authority, agency, commission, tribunal or body, domestic, foreign or
supranational.

          Section 3.4    No Violation.  Neither the execution or delivery of
this Agreement by the Company nor the consummation by the Company of the
transactions contemplated hereby will (i) constitute a breach or violation of
any provision of the Articles of Incorporation, as amended, or By-Laws of the
Company or (ii) except as set forth on Section 3.4 of the Disclosure Schedule,
constitute a breach, violation or default (or any event which, with notice or
lapse of time or both, would constitute a default) under, or result in the
termination of, or accelerate the performance 

                                      -8-
<PAGE>
 
required by, or permit a third party to terminate or accelerate vesting or
repurchase rights, or result in the creation of any Lien upon any of the
properties or assets of the Company or any of its Subsidiaries, or any other
detriment under, any note, bond, mortgage, indenture, deed of trust, license,
lease, agreement or other instrument to which the Company or any of its
Subsidiaries is a party or by which they or any of their respective properties
or assets are bound, other than breaches, violations, defaults, terminations,
accelerations or creation of Liens which, in the aggregate, would not have a
Material Adverse Effect on the Company.

          Section 3.5    SEC Reports and Financial Statements.  Since January 1,
1995, the Company has filed all forms, reports  and documents ("SEC Reports")
with the SEC required to be filed by it pursuant to the federal securities laws
and the SEC rules and regulations thereunder. Copies of all such SEC Reports
have been made available to ICS by the Company or are publicly available on
EDGAR.  None of such SEC Reports (as of their respective filing dates) contained
any untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading except as subsequently disclosed.  The audited and unaudited
consolidated financial statements of the Company included in the SEC Reports
have been prepared in accordance with generally accepted accounting principles
applied on a consistent basis (except as otherwise stated in such financial
statements, including the related notes) and fairly present the financial
position of the Company and its consolidated Subsidiaries as of the dates
thereof and the results of their operations and changes in financial position
for the periods then ended, subject, in the case of the unaudited financial
statements, to year-end audit adjustments. Except as set forth in the SEC
Reports and except as disclosed in Section 3.5 of the Disclosure Schedule, at
the date of the most recent audited financial statements of the Company included
in the SEC Reports, neither the Company nor any of its Subsidiaries had, and
since such date neither the Company nor any of such Subsidiaries has incurred,
any liabilities or obligations of any nature (whether accrued, absolute,
contingent or otherwise) which, individually or in the aggregate, would be
required to be disclosed in a balance sheet of the Company prepared in
accordance with generally accepted accounted principles except liabilities
incurred in the ordinary and usual course of business and consistent with past
practice, liabilities incurred in connection with the transactions contemplated
by this Agreement, and liabilities that would not reasonably be expected to have
a Material Adverse Effect with respect to the Company.

          Section 3.6    Compliance with Applicable Laws.  Except as set forth
on Section 3.6 of the Disclosure Schedule and except for matters relating to
Environmental Laws (which matters are covered in Section 3.12 hereof) or matters
relating to real estate (which matters are covered in Section 3.24 hereof), (i)
the Company and its Subsidiaries possess all permits, licenses, certifications
and other governmental or regulatory authorizations and approvals necessary to
enable the Company and its Subsidiaries to carry on their business as presently
conducted except for such failures to have such permits, licenses,
certifications or regulatory authorizations or approvals that would not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect, and all such permits are valid, and in full force and effect and
there exists no default thereunder and (ii) the operations of the Company and
its Subsidiaries have been conducted in compliance with all laws, ordinances,
regulations, judgments and decrees of any Governmental Entity applicable to the
Company or such Subsidiary or by which it may be bound, except for possible
violations which

                                      -9-
<PAGE>
 
would not, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect.

          Section 3.7    Litigation.  Section 3.7 of the Disclosure Schedule
sets forth any suit, claim, action, proceeding or investigation pending or, to
the knowledge of the Company, threatened, at law or in equity, or before any
Governmental Entity, against the Company or any of its Subsidiaries, none of
which, individually or in the aggregate, would reasonably be expected to have a
Material Adverse Effect on the Company or would reasonably be expected to
prevent or materially delay the consummation of the transactions contemplated by
this Agreement.  Except as disclosed in the SEC Reports filed prior to the date
of this Agreement, neither the Company nor any of its Subsidiaries is subject to
any outstanding order, writ, injunction or decree which, individually or in the
aggregate, would reasonably be expected to have a Material Adverse Effect on the
Company or could prevent or materially delay the consummation of the
transactions contemplated hereby.

          Section 3.8    Information.  None of the information supplied by the
Company in writing specifically for inclusion or incorporation by reference in
(i) the Proxy Statement (as hereinafter defined) or (ii) any other document to
be filed with the SEC or any other Governmental Entity in connection with the
transactions contemplated by this Agreement (the "Other Filings") will, at the
respective times filed with the SEC or other Governmental Entity and, in
addition, in the case of the Proxy Statement, at the date it or any amendment or
supplement is mailed to shareholders, at the time of the Special Meeting (as
hereinafter defined) and at the Effective Time, contain any untrue statement of
a material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements made therein, in light of the
circumstances under which they were made, not misleading.  Notwithstanding the
foregoing, no representation is made by the Company with respect to (i) any
forward-looking information which may have been supplied by the Company, or (ii)
statements made in any of the foregoing documents based upon information
supplied by ICS.

          Section 3.9    Certain Approvals.  The Company Board has taken any and
all necessary and appropriate action to approve the Merger and the transactions
contemplated by this Agreement, including for the purposes of Sections
2538(b)(1) and 2555(1) of the BCL.

           Section 3.10   Employee Benefit Plans.

                (a) Section 3.10(a) of the Disclosure Schedule includes a true
and complete list of all material employee benefit plans and programs providing
benefits to any employee or former employee of the Company and its Subsidiaries
sponsored or maintained by the Company or any of its Subsidiaries or to which
the Company or any of its Subsidiaries contributes or is obligated to contribute
("Plans"). Without limiting the generality of the foregoing, the term "Plans"
includes all employee welfare benefit plans within the meaning of Section 3(1)
of the Employee Retirement Income Security Act of 1974, as amended, and the
regulations thereunder ("ERISA"), and all employee pension benefit plans within
the meaning of Section 3(2) of ERISA.

                (b) With respect to each Plan, the Company has made available to
ICS a true, correct and complete copy of: (i) all plan documents, benefit
schedules, trust agreements, and 

                                      -10-

insurance contracts and other funding vehicles; (ii) the most recent Annual
Report (Form 5500 Series) and accompanying schedule, if any; (iii) the current
summary plan description, if any; (iv) the most recent annual financial report,
if any; (v) the most recent actuarial report, if any; and (vi) the most recent
determination letter from the United States Internal Revenue Service (the
"IRS"), if any.

                (c) The Company and each of its Subsidiaries has complied, and
is now in compliance, in all material respects with all provisions of ERISA, the
Internal Revenue Code of 1986, as amended, including the Treasury Regulations
thereunder (the "Code") and all laws and regulations applicable to the Plans.
With respect to each Plan that is intended to be a "qualified plan" within the
meaning of Section 401(a) of the Code ("Qualified Plans"),(i) such Plan is a
Qualified Plan within the meaning of Section 401(a) of the Code, (ii) such
Qualified Plans are within the remedial amendment period and (iii) the Company
will submit such Qualified Plans to the IRS for a favorable determination letter
within the remedial amendment period.

                (d) All contributions required to be made to any Plan by
applicable law or regulation or by any plan document or other contractual
undertaking, and all premiums due or payable with respect to insurance policies
funding any Plan, for any period through the date hereof have been timely made
or paid in full or, to the extent not required to be made or paid on or before
the date hereof, have been fully reflected in the financial statements of the
Company included in the SEC Reports to the extent required under generally
accepted accounting principles.

                (e) Except as set forth on Section 3.10(e) of the Disclosure
Schedule, no Plan is subject to Title IV or Section 302 of ERISA or Section 412
or 4971 of the Code. Without limiting the generality of the foregoing, no Plan
is a "multiemployer plan" within the meaning of Section 4001(a)(3) of ERISA (a
"Multiemployer Plan") or a plan that has two or more contributing sponsors at
least two of whom are not under common control, within the meaning of Section
4063 of ERISA and which is subject to Title IV of ERISA (a "Multiple Employer
Plan").

                (f) There does not now exist, nor do any circumstances exist
that could result in, any material liability under (i) Title IV of ERISA, (ii)
Section 302 of ERISA, (iii) Sections 412 and 4971 of the Code, (iv) the
continuation coverage requirements of section 601 et seq. of ERISA and Section
4980B of the Code, or (v) corresponding or similar provisions of foreign laws or
regulations, other than a liability that arises solely out of, or relates solely
to, the Plans, that would be a liability of the Company or any of its
Subsidiaries following the Effective Time. Without limiting the generality of
the foregoing, none of the Company, its Subsidiaries nor any ERISA Affiliate of
the Company or any of its Subsidiaries has engaged in any transaction described
in Section 4069 or Section 4204 or 4212 of ERISA. An "ERISA Affiliate" means any
entity, trade or business that is a member of a group described in Section
414(b), (c), (m) or (o) of the Code or Section 4001(b)(1) of ERISA that includes
the Company or any of its Subsidiaries, or that is a member of the same
"controlled group" as the Company or any of its Subsidiaries, pursuant to
Section 4001(a)(14) of ERISA.

           Section 3.11   Taxes.

                (a) The Company and each of its Subsidiaries has timely filed
all federal, state, local and foreign income Tax Returns (as hereinafter
defined) required to be filed by it in all jurisdictions in which it is required
to do so, and all other material Tax Returns required to be filed by it, and
such Tax Returns are true and complete in all material respects, and the Company
and each of its Subsidiaries has paid or caused to be paid all Taxes (as
hereinafter defined) shown due on such Tax Returns and has made adequate
provision in the Company's financial statements for payment of all Taxes that
are not payable as of the date hereof or have not been paid, in respect of all
taxable periods or portions thereof ending on or before the date hereof, except
where the failure to so file or pay or make adequate provision would not,
individually or in the aggregate, have a Material Adverse Effect on the Company.
All Tax Returns for the Company in respect of all years not barred by the
statute of limitations have heretofore been made available by the Company to ICS
and are listed in Section 3.11 of the Disclosure Schedule. There are no
outstanding Agreements, waivers or requests for waivers extending the statutory
period of limitation applicable to any Tax Return of the Company or any of its
Subsidiaries. Except as set forth on Section 3.11 of the Disclosure Schedule,
neither the Company nor any of its Subsidiaries (i) has been a member of a group
filing consolidated returns for federal income tax purposes (except for the
group of which the Company is the common parent), (ii) is a party to or has any
liability pursuant to a Tax sharing or Tax indemnity agreement or any other
agreement of a similar nature that remains in effect or (iii) has any liability
for the Taxes of any person (other than any of the Company or its Subsidiaries)
under Treas. Reg. (S) 1.1502-6 (or any similar provision of state, local, or
foreign law), as a transferee or successor, by contract, or otherwise. The
Company will attach to its June 27, 1998, Tax Return the statement required
under Treasury Regulation Section 1.1502-20(c)(3) related to the disposition of
its shares in Voyetra Technologies, Inc. Except as set forth in Section 3.11 of
the Disclosure Schedule, no claim has ever been made by a taxing authority in a
jurisdiction where the Company or any of its Subsidiaries does not file Tax
Returns that such person is or may be subject to taxation by such jurisdiction.
None of the Company or its Subsidiaries will be required to include any item of
income in, or exclude any item of deduction from, taxable income for any taxable
period (or portion thereof) ending after the Closing Date as a result of any (i)
change in method of accounting for a taxable period ending on or prior to the
Closing Date under Code (S) 481(c) (or any corresponding or similar provision of
state, local or foreign income Tax law), (ii) "closing agreement" as described
in Code (S) 7121 (or any corresponding or similar provision of state, local or
foreign income Tax law) or (iii) deferred intercompany gain or any excess loss
account described in Treasury Regulations under Code Section 1502. None of the
Company or its Subsidiaries is a party to any agreement, contract, arrangement
or plan that has resulted or would result, separately or in the aggregate, in
the payment of any "excess parachute payment" within the meaning of Code (S)
280G (or any corresponding provision of state, local or foreign income Tax law).

                (b) For purposes of this Agreement, the term "Taxes" means all
taxes, charges, fees, levies or other assessments, including, without
limitation, income, gross receipts, excise, property, sales, transfer, license,
payroll, withholding, capital stock and franchise taxes, imposed by the United
States or any state, local or foreign government or subdivision or agency
thereof, including any interest, penalties or additions thereto. For purposes of

term "Tax Return" means any report, return or other information or document
required to be supplied to a taxing authority in connection with Taxes.

           Section 3.12   Environmental Matters.

except for such matters that, individually or in the aggregate, would not
reasonably be expected to have a Material Adverse Effect:

                (a) with respect to the Business, the Company and its

centuries, including leap year calculations.

ownership, lease, use, occupancy or operation by any person of the Real Property
(except for Permitted Liens).

          (e) Current Use.  The current use of the Owned Real Property does not
violate in any material respect any instrument of record or agreement affecting

restriction, easement, agreement or order of any 

                                      -20-
<PAGE>
 
governmental authority having jurisdiction over any of the Owned Real Property
that affects such real property or the use or occupancy thereof (except for
Permitted Liens). No damage or destruction has occurred with respect to any of
the Owned Real Property that, individually or in the aggregate, has had or
resulted in, or will have or result in, a Material Adverse Effect on the
Company.

improvements included within the Real Property (the "Improvements") are in good
condition and repair and adequate to operate such facilities as currently used,
and, to the best of the Company's knowledge and belief, there are no facts or
conditions affecting any of the Improvements which would, individually or in the
aggregate, interfere in any significant respect with the use, occupancy or
operation thereof which would reasonably be expected to have a Material Adverse
Effect on the Company as currently used, occupied or operated or intended to be
used, occupied or operated.  No Improvement or portion thereof is dependent for
its access, operation or utility on any land, building or other improvement not
included in the Real Property.

          (g) Permits.  All required or appropriate certificates of occupancy,
permits, licenses, franchises, approvals and authorizations (collectively, the
"Real Property Permits") of all governmental authorities having jurisdiction

Effect on the Company, have been issued to the Company to enable the Real
Property to be lawfully occupied and used for all of the purposes for which it
is currently occupied and used have been lawfully issued and are, as of the date
hereof, in full force and effect.  The Company has delivered complete and
correct copies of the Real Property Permits to ICS.  The Company has not
received or been informed by a third party of the receipt by it of any notice
which could have a Material Adverse Effect on the Company from any governmental
authority having jurisdiction over the Real Property threatening a suspension,
revocation, modification or cancellation of any Real Property Permit and, to the
best knowledge of the Company, there is no basis for the issuance of any such
notice or the taking of any such action.

the Company. Except as set forth in Section 3.13 of the Disclosure Schedule,

failure to be in good standing or to so qualify would have a Material Adverse
Effect on ICS.  The term "Material Adverse Effect on ICS", as used in this
Agreement, means any change in or effect on the 

                                      -21-
<PAGE>
 
business, financial condition, results of operations or reasonably foreseeable
prospects of ICS or any of its Subsidiaries that would be materially adverse to
ICS.

           Section 4.2   Authority Relative to this Agreement.

                (a) ICS has full corporate power and authority to execute and
deliver this Agreement and to consummate the transactions contemplated hereby.
The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly and validly authorized by the
Board of Directors of ICS and no other corporate proceedings on the part of ICS
are necessary to authorize this Agreement or to consummate the transactions so
contemplated. This Agreement has been duly and validly executed and delivered by
ICS and, assuming this Agreement constitutes a valid and binding obligation of
the Company, this Agreement constitutes a valid and binding agreement of ICS,
enforceable against ICS in accordance with its terms.

                (b) Other than in connection with, or in compliance with, the
provisions of the BCL, the Exchange Act, the securities laws of the various
states and the HSR Act, no authorization, consent or approval of, or filing
with, any Governmental Entity is necessary for the consummation by ICS of the
transactions contemplated by this Agreement other than authorizations, consents
and approvals the failure to obtain, or filings the failure to make, which would
not, in the aggregate, have a Material Adverse Effect on ICS.

          Section 4.3    No Violation.  Neither the execution or delivery of
this Agreement by ICS nor the consummation by ICS of the transactions
contemplated hereby will (i) constitute a breach or violation of any provision
of the Articles of Incorporation, as amended, or By-Laws of ICS or (ii)
constitute a breach, violation or default (or any event which, with notice or
lapse of time or both, would constitute a default) under, or result in the
termination of, or accelerate the performance required by, or result in the
creation of any Lien upon any of the properties or assets of ICS under, any
note, bond, mortgage, indenture, deed of trust, license, lease, agreement or
other instrument to which ICS is a party or by which it or any of its properties
or assets are bound, other than breaches, violations, defaults, terminations,
accelerations or creation of Liens which, in the aggregate would not have a
Material Adverse Effect on ICS.

          Section 4.4    Information.  None of the information supplied by ICS
in writing (other than projections of future financial performance) specifically
for inclusion or incorporation by reference in (i) the Proxy Statement or (ii)
the Other Filings will, at the respective times filed with the SEC or other
Governmental Entity and, in addition, in the case of the Proxy Statement, at the
date it or any amendment or supplement is mailed to shareholders, at the time of
the Special Meeting and at the Effective Time, contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements made therein, in light of the
circumstances under which they were made, not misleading. Notwithstanding the
foregoing, no representation is made by ICS with respect to statements made in
any of the foregoing documents based upon information supplied by the Company.

                                      -22-

          Section 4.5    Financing.  Section 6.2(e) of the Disclosure Schedule
sets forth true and complete copies of written documentation from third parties
which provides for financing in amounts sufficient to consummate the
transactions contemplated hereby as contemplated by Section 6.2(e) hereof.  The
commitment fees set forth in such financing documents which are due and payable
have been paid.

execution of this Agreement, an "interested stockholder" within the meaning of

ICS does not "beneficially own" (as defined in Rule 13d-3 under the Exchange
Act) more than 1% of the outstanding shares of Common Shares or any securities
convertible into, or exchangeable for, Common Shares.  ICS will not buy
additional Common Shares between the date of this Agreement and the Closing.

          Section 4.8    Brokers.  Except as set forth on Schedule 4.8 of the
Disclosure Schedule, no broker, finder or investment banker is entitled to any
brokerage, finder's or other fee or commission in connection with the
transactions contemplated by this Agreement based upon arrangements made by or
on behalf of ICS, that is or will be payable by the Company or any of its
Subsidiaries.  No fee is due to any such person if the transactions contemplated
hereby are not consummated.

          Section 4.9    Formation of ICS; No Prior Activities.  ICS was formed
solely for the purpose of engaging in the transactions contemplated by this
Agreement.  As of the date hereof and the Effective Time, except for (a)
obligations or liabilities incurred in connection with its incorporation or
organization and the transactions contemplated by this Agreement, and (b) this
Agreement and any other agreements or arrangements contemplated by this
Agreement or in furtherance of the transactions contemplated hereby, ICS has not
incurred, directly or indirectly, through any subsidiary or affiliate, any
obligations or liabilities, owned any assets or engaged in any business
activities of any type or kind whatsoever or entered into any agreements or
arrangements with any Person.

          Section 4.10    Litigation.  There is no suit, claim, action,
proceeding or investigation pending or, to the knowledge of ICS, threatened, at
law or in equity, or before any Governmental Entity, against ICS, which could
prevent or materially delay the consummation of the transactions contemplated by
this Agreement.

                                   COVENANTS

          Section 5.1    Conduct of Business of the Company. Except as
contemplated by this Agreement or as expressly agreed to in writing by ICS,
during the period from the date of this Agreement to the Effective Time, the
Company will, and will cause each of its Subsidiaries to, conduct its operations
according to its ordinary and usual course of business and consistent with past

                                      -23-

practice and use its and their respective commercially reasonable efforts to
preserve intact their current business organizations, keep available the
services of their current officers and employees and preserve their
relationships with customers, suppliers, licensors, licensees, advertisers,
distributors and others having business dealings with them and to preserve
goodwill.  Without limiting the generality of the foregoing, and except as (x)
otherwise expressly provided in this Agreement, (y) required by law, or (z) set
forth on Section 5.1 of the Disclosure Schedule, prior to the Effective Time,
the Company will not, and will cause its Subsidiaries not to, without the
consent of ICS (which consent shall not be unreasonably withheld):

               (a) except with respect to annual bonuses made in the ordinary
     course of business consistent with past practice, adopt or amend in any
     material respect any bonus, profit sharing, compensation, severance,
     termination, stock option, stock appreciation right, pension, retirement,

     course of business consistent with past practice);

               (b) incur any indebtedness for borrowed money;

               (c) expend funds for capital expenditures in excess of
     $1,000,000;

               (d) sell, lease, license, mortgage or otherwise encumber or

     properties or assets), except in the ordinary course of business consistent
     with past practice;

               (e) (x) declare, set aside or pay any dividends on, or make any

     or authorize the issuance of any other securities in respect of, in lieu of

     its Subsidiaries or any other securities thereof or any rights, warrants or
     options to acquire any such shares or other securities;

               (f) authorize for issuance, issue, deliver, sell or agree or

     purchase or otherwise), pledge, dispose of or otherwise encumber any shares
     of its capital stock or the capital stock of any of its Subsidiaries, any

     securities or convertible 

                                      -24-

     securities or any other securities or equity equivalents (including without
     limitation stock appreciation rights) (other than issuances upon exercise
     of Options or pursuant to the Stock Plans);

               (g) amend its Articles of Incorporation, as amended, By-Laws or
     equivalent organizational documents or alter through merger, liquidation,

     out of the transactions contemplated hereby or any other litigation
     (whether or not commenced prior to the date of this Agreement) or settle,
     pay or compromise any claims not required to be paid; provided, however,
     that the Company may settle, pay and compromise claims in an aggregate
     amount not in excess of $1,000,000 in consultation and cooperation with
     ICS; or

               (j) take any action which is not set forth on Section 3.13 of the
     Disclosure Schedule, if taken after June 27, 1998, but prior to the date
     hereof, that would have caused the representations and warranties contained
     in Section 3.13 hereof to be untrue.

          Section 5.2    Access to Information.  From the date of this Agreement
until the Effective Time, the Company will, and will cause its Subsidiaries, and
each of their respective officers, directors, employees, agents or other
representatives (including, without limitation, any investment banker, attorney
or accountant retained by the Company or its Subsidiaries) (the "Company
Representatives") to, give ICS and their respective officers, employees, agents
or other representatives (including, without limitation, any investment banker,
attorney or accountant retained by ICS) (the "ICS Representatives") and
representatives of financing sources identified by ICS reasonable access, upon
reasonable notice and during normal business hours, to the offices and other
facilities and to the books and records of the Company and its Subsidiaries and
will cause the Company Representatives and the Company's Subsidiaries to furnish
ICS and the ICS Representatives and representatives of financing sources
identified by ICS with such financial and operating data and such other
information with respect to the business and operations of the Company and its
Subsidiaries as ICS and representatives of financing sources identified by ICS
may from time to time reasonably request. ICS agrees that any information
furnished pursuant to this Section 5.2 will be subject to the provisions of the
letter agreement dated May 15, 1998, between Bain Capital, Inc. and the Company
(the "Confidentiality Agreement").

           Section 5.3   Efforts.

                (a) Each of the Company and ICS shall, and the Company shall
cause each of its Subsidiaries to, use commercially reasonable efforts to take
all action to do all things necessary to consummate and make effective the
transactions contemplated by this Agreement (including the satisfaction, but not
waiver, of the closing conditions set forth in Article 6). In furtherance and
not in limitation of the foregoing, each of the Company and ICS shall, and the
Company shall cause each of its Subsidiaries to, make all necessary filings with
Governmental Entities as promptly as practicable in order to facilitate prompt
consummation of the transactions contemplated by this Agreement. In addition,
each of ICS and the Company will use its commercially reasonable efforts
(including, without limitation, payment of any required fees) and will cooperate
fully with each other to (i) comply as promptly as practicable with all
governmental requirements applicable to the transactions contemplated by this
Agreement, including the making of all filings necessary or proper under
applicable laws and regulations to consummate and make effective the
transactions contemplated by this Agreement, including, but not limited to, the
Proxy Statement or other foreign filings and any amendments to any thereof and
(ii) obtain promptly all consents, waivers, approvals, authorizations or permits
of, or registrations or filings with or notifications to (any of the foregoing
being a "Consent"), any Governmental Entity necessary for the consummation of
the transactions contemplated by this Agreement (except for such Consents the
failure of which to obtain would not prevent or materially delay the
consummation of the Merger). Subject to the Confidentiality Agreement, ICS and
the Company shall furnish to one and other such necessary information and
reasonable assistance as ICS or the Company may reasonably request in connection
with the foregoing.

                (b) Without limiting Section 5.3(a) hereof, ICS and the Company
shall each (i) promptly make or cause to be made the filings required of such
party under the HSR Act with respect to the Merger; (ii) use its best efforts to
avoid the entry of, or to have vacated or terminated, any decree, order, or
judgment that would restrain, prevent or delay the consummation of the Merger,
including without limitation defending through litigation on the merits any
claim asserted in any court by any third party; and (iii) take any and all steps
which, in such party's judgment, are commercially reasonable to avoid or
eliminate each and every impediment under any antitrust, competition, or trade
regulation law that may be asserted by any Governmental Entity with respect to
the Merger so as to enable consummation thereof to occur as soon as reasonably
possible. Each party hereto shall promptly notify the other parties of any
communication to that party from any Governmental Entity and permit the other
parties to review in advance any proposed communication to any Governmental
Entity. ICS and the Company shall not (and shall cause their respective
affiliates and representatives not to) agree to participate in any meeting with
any Governmental Entity in respect of any filings, investigation or other
inquiry unless it consults with the other party in advance and, to the extent
permitted by such Governmental Entity, gives the other party the opportunity to
attend and participate thereat. Subject to the Confidentiality Agreement, each
of the parties hereto will coordinate and cooperate fully with the other parties
hereto in exchanging such information and providing such assistance as such
other parties may reasonably request in connection with the foregoing and in
seeking early termination of any applicable waiting periods under the HSR Act or
in connection with other Consents. Each of the Company and ICS agrees to respond
promptly to and comply fully with any request for additional information or

                                      -26-
<PAGE>
 
documents under the HSR Act. Subject to the Confidentiality Agreement, the
Company will provide ICS, and ICS will provide the Company, with copies of all
correspondence, filings or communications (or memoranda setting forth the
substance thereof) between such party or any of its representatives, on the one
hand, and any Governmental Entity or members of its staff, on the other hand,
with respect to this Agreement and the transactions contemplated hereby.

                (c) ICS shall use commercially reasonable efforts to cause the
financing necessary for satisfaction of the condition in Section 6.2(e) hereof
to be obtained on the terms set forth in the commitment letters attached to
Section 6.2(e) of the Disclosure Schedule; provided, however, that ICS shall be
entitled to (i) enter into commitments for equity and debt financing with other
nationally recognized financial institutions, which commitments will have
substantially the same terms as those set forth in the commitment letters and
which commitments may be substituted for such commitment letters and (ii) modify
the capital structure set forth in such commitment letters so long as (A) the
total committed common equity equals at least $50 million (including Rollover
Shares), (B) the Merger Consideration paid to all shareholders of the Company is
no less than otherwise would have been paid in accordance with this Agreement
and (C) such modified financing is no less certain than that set forth in such
commitment letter.

                (d) The Company agrees to provide, and will cause its
Subsidiaries and its and their respective officers, employees and advisors to
provide, all reasonable cooperation in connection with the arrangement of any
financing in respect of the transactions contemplated by this Agreement,
including, without limitation, (i) participation in meetings, due diligence
sessions and road shows, (ii) assisting the preparation of offering memoranda,
private placement memoranda, prospectuses and similar documents, and (iii) the
execution and delivery of any commitment letters, underwriting or placement
agreements, pledge and security documents, other definitive financing documents,
or other requested certificates or documents as may be requested by ICS;
provided that the form and substance of any of the material documents referred
to in clause (ii), and the terms and conditions of any of the material
agreements and other documents referred to in clause (iii), shall be
substantially consistent with the terms and conditions of the financing required
to satisfy the condition set forth in Section 6.2(e) hereof; and provided,
further, that no such person or entity will be required to incur any costs or
expenses in connection with this Section 5.3(d) or to execute or deliver any of
the agreements or other documents referred to in clause (iii) unless Bain
Capital, Inc. and Bear, Stearns & Co., Inc. shall have agreed to indemnify such
person or entity against all costs and expenses arising in connection with this
Section 5.3(d) and any liability arising under such agreements or other
documents in the event the transactions contemplated by this Agreement are not
consummated.

          Section 5.4    Title Insurance and Surveys.  In the event that the
Company has not consummated the transactions related to the sale/leaseback of
the Valley Forge facility by the Closing, the Company shall use its reasonable
efforts to assist ICS in obtaining: (1) a title insurance policy of the Valley
Forge facility together with all affidavits, undertakings, endorsements and
other title clearance documents necessary to issue such title policy to ICS and
its lender and (2) an ALTA Survey certified to ICS, its lender and any other
party reasonably requested by ICS.

          Section 5.5    Public Announcements.  The Company, on the one hand,
and ICS, on the other hand, agree to consult promptly with each other prior to
issuing any material press release or announcement or otherwise making any
material public statement with respect to the Merger and the other transactions
contemplated hereby, agree to provide to the other party for review a copy of
any such press release or statement, and shall not issue any such press release
or make any such public statement prior to such consultation and review, unless
required by applicable law or any listing agreement with a securities exchange
or the Nasdaq Stock Market, Inc.

           Section 5.6   Employee Benefit Arrangements.

                (a) The Company will honor, and, from and after the Effective
Time, the Surviving Corporation will honor, in accordance with their respective
terms as in effect on the date hereof, the employment, severance and bonus
agreements and arrangements to which the Company is a party.

                (b) The Company agrees that for a period of one year following
the Effective Time, the Surviving Corporation shall continue the (i)
compensation (including bonus and incentive awards) programs and plans and (ii)
employee benefit and welfare plans, programs, contracts, agreements and policies
(including insurance and pension plans), fringe benefits and vacation policies
which are currently provided by the Company; provided that notwithstanding
anything in this Agreement to the contrary the Surviving Corporation shall not
be required to maintain any individual plan or program so long as the benefit
plan and agreements maintained by the Surviving Corporation are, in the
aggregate, not materially less favorable than those provided by the Company
immediately prior to the date of this Agreement; and, provided, further, that
nothing in this sentence shall be deemed to limit or otherwise affect the right
of the Surviving Corporation to terminate employment or change the place of
work, responsibilities, status or designation of any employee or group of
employees as the Surviving Corporation may determine in the exercise of its
business judgment and in compliance with applicable laws.

           Section 5.7   Indemnification; Directors' and Officers' Insurance.

                (a) The Company and, from and after the Effective Time, the
Surviving Corporation, shall indemnify, defend and hold harmless the present and
former officers, directors, employees and agents of the Company and its
Subsidiaries (the "Indemnified Parties") against all judgments, fines, losses,
claims, damages, costs or expenses (including reasonable attorneys' fees) or
liabilities arising out of or related to matters, actions or omissions or
alleged actions or omissions occurring at or prior to the Effective Time whether
asserted or claimed prior to or after the Effective Time (i) to the full extent
permitted by Pennsylvania law or, if the protections afforded thereby to an
Indemnified Person are greater, (ii) to the same extent and on the same terms
and conditions (including with respect to advancement of expenses) provided for
in the Company's Articles of Incorporation, as amended, and By-Laws and
agreements in effect at the date hereof (to the extent consistent with
applicable law), which provisions will survive the Merger and continue in full
force and effect after the Effective Time. Without limiting the foregoing, (i)
ICS shall, and shall cause the Surviving Corporation to, periodically advance
expenses (including attorney's fees) as incurred by an Indemnified Person with
respect to the foregoing to the full extent permitted under applicable law, 

                                      -28-
<PAGE>
 
and (ii) any determination required to be made with respect to whether an
Indemnified Party shall be entitled to indemnification shall, if requested by
such Indemnified Party, be made by independent legal counsel selected by the
Surviving Corporation and reasonably satisfactory to such Indemnified Party.

                (b) ICS agrees that the Company, and, from and after the
Effective Time, the Surviving Corporation, shall cause to be maintained in
effect for not less than six years from the Effective Time the current policies
of the directors' and officers' liability insurance maintained by the Company;
provided that the Surviving Corporation may substitute therefor other policies
of at least the same coverage amounts and which contain terms and conditions not
less advantageous to the beneficiaries of the current policies and, provided
further, that such substitution shall not result in any gaps or lapses in
coverage with respect to matters occurring on or prior to the Effective Time;
and provided further, that the Surviving Corporation shall not be required to
pay an annual premium in excess of 200% of the last annual premium paid by the
Company prior to the date hereof and if the Surviving Corporation is unable to
obtain the insurance required by this Section 5.7(b) it shall obtain as much
comparable insurance as possible for an annual premium equal to such maximum
amount.

                (c) This Section 5.7 shall survive the consummation of the
Merger at the Effective Time, is intended to benefit the Company, the Surviving
Corporation and the Indemnified Parties, shall be binding on all successors and
assigns of ICS and the Surviving Corporation, and shall be enforceable by the
Indemnified Parties.

          Section 5.8    Notification of Certain Matters.  ICS and the Company
shall promptly notify each other of (i) the occurrence or non-occurrence of any
fact or event which would be reasonably likely (A) to cause any representation
or warranty contained in this Agreement to be untrue or inaccurate in any
material respect at any time from the date hereof to the Effective Time or (B)
to cause any covenant, condition or agreement under this Agreement not to be
complied with or satisfied and (ii) any failure of the Company, or ICS, as the
case may be, to comply with or satisfy any covenant, condition or agreement to
be complied with or satisfied by it hereunder; provided, however, that no such
notification shall affect the representations or warranties of any party or the
conditions to the obligations of any party hereunder.  Each of the Company and
ICS shall give prompt notice to the other parties hereof of any notice or other
communication from any third party alleging that the consent of such third party
is or may be required in connection with the transactions contemplated by this
Agreement.

          Section 5.9    State Takeover Laws.  The Company shall, upon the
request of ICS, take all reasonable steps to assist in any challenge by ICS to
the validity or applicability to the transactions contemplated by this
Agreement, including the Merger, of any state takeover law.

           Section 5.10   No Solicitation.

                (a) From and after the date hereof until the termination of this
Agreement, the Company and its affiliates shall not, and shall instruct the
Company Representatives not to:

                                      -29-
<PAGE>
 
               (i) directly or indirectly solicit, initiate, or encourage
     (including by way of furnishing nonpublic information or assistance), or
     take any other action to facilitate, any inquiries or proposals from any
     person that constitute, or may reasonably be expected to lead to, an
     acquisition, purchase, merger, consolidation, share exchange,
     recapitalization, business combination or other similar transaction
     involving any material portion of the assets or any securities of, any
     merger, consolidation or business combination with, or any public
     announcement of a proposal, plan, or intention to do any of the foregoing
     by, the Company or any of its Subsidiaries (such transactions being
     referred to herein as "Acquisition Proposals"); except that none of the
     foregoing restrictions shall apply with respect to persons to whom the
     Company or a Company Representative has already provided, within the three
     months prior to the date of this Agreement, non-public written information
     about the Company to facilitate an Acquisition Proposal;

               (ii) enter into, maintain, or continue discussions or
     negotiations with any person in furtherance of such inquiries or to obtain
     an Acquisition Proposal; except that none of the foregoing restrictions
     shall apply with respect to persons to whom the Company or a Company
     Representative has already provided, within the three months prior to the
     date of this Agreement, non-public written information about the Company to
     facilitate an Acquisition Proposal;

               (iii) agree to or endorse any Acquisition Proposal;

               (iv) enter into any agreement, arrangement or understanding
     requiring it to abandon, terminate or fail to consummate the Merger or any
     other transaction contemplated by this Agreement, or

               (v) authorize or permit the Company Representatives to take any
     such action except to the extent that such action may be taken under clause
     (i) or (ii) of this Section 5.10(a); 

          provided, however, that prior to the approval of the Merger by the
shareholders of the Company nothing in this Agreement shall prohibit the Company
Board or a special committee of the Company Board (the "Special Committee") from
(A)  furnishing information to, and engaging in discussions or negotiations
with, any person or entity that makes an unsolicited written, bona fide proposal
to acquire the Company and/or its Subsidiaries pursuant to a merger,
consolidation, share exchange, tender offer or other similar transaction, but
only to the extent that the Company Board or the Special Committee determines in
good faith by a majority vote, based upon advice from independent legal counsel
(who may be the Company's regularly engaged outside legal counsel), a
description of which is provided to ICS, that failure to furnish such
information or engage in such discussions or negotiations with such person or
entity would be reasonably likely to constitute a breach of the fiduciary duties
to shareholders of the Company Board or the Special Committee under applicable
law (assuming for such purpose that fiduciary duties are owed only to
shareholders), and such a proposal is, in the opinion of the Investment Banks
more favorable to the Company and the shareholders of the Company from a
financial point of view then than the transactions contemplated by this
Agreement (including any adjustment to the terms and

                                      -30-

conditions of such transactions proposed by ICS in response to such Acquisition
Proposal) (any such Acquisition Proposal satisfying such criteria, a "Higher
Offer"), provided that, prior to accepting the Higher Offer, the Company Board
notifies ICS of its intentions and obtains an executed confidentiality agreement
from the appropriate parties substantially similar to the Confidentiality
Agreement, (B) failing to make or withdrawing or modifying its recommendation
referred to in Section 5.13 hereof if the Company Board, after consultation with
independent legal counsel (who may be the Company's regularly engaged outside
legal counsel), determines in good faith that such action is consistent with the
Company Board's fiduciary duties to shareholders under applicable law, provided
that ICS is given five days' prior written notice of its intentions to do so,
and (C) disclosing to the Company's shareholders a position contemplated by
Rules 14d-9 and 14e-2 promulgated under the Exchange Act with respect to any
tender offer, or taking any other legally required action (including, without
limitation, the making of public disclosure as may be necessary or advisable
under applicable securities laws); and, provided further, that the Company
Board's or the Special Committee's exercise of its rights under clause (A), (B)
or (C) above shall not constitute a breach by the Company of this Agreement.

                (b) The Company will promptly notify ICS of the receipt of any
Acquisition Proposal, the terms and conditions of such proposal and, if not
prohibited by the terms of such proposal, the identity of the person making it.
The Company will have no obligation to notify ICS of any change to or
modification of such Acquisition Proposal or the terms and conditions thereof,
but shall provide ICS with a reasonable opportunity to increase the Merger
Consideration in response to such Acquisition Proposal.

          Section 5.11    Interim Liabilities.  The Surviving Corporation will
pay, consistent with past practice, all liabilities, including all accounts

Agreement until the Effective Date.

            Section 5.13    Shareholders' Meeting.

                (a) The Company, acting through the Company Board, shall, in
accordance with applicable law:

               (i) duly call, give notice of, convene and hold a special meeting
     of its shareholders (the "Special Meeting") as soon as practicable
     following the execution of this Agreement for the purpose of considering
     and taking action upon this Agreement;

               (ii) prepare and file with the SEC a preliminary proxy statement
     relating to this Agreement, and use its reasonable efforts (A) to obtain
     and furnish the information required to be included by the SEC in a
     definitive proxy statement (the "Proxy Statement") and, after consultation
     with ICS, to respond promptly to any comments made by the SEC with respect
     to the preliminary proxy statement and cause the Proxy Statement to 

                                      -31-
<PAGE>
 
     be mailed to its shareholders and (B) to obtain the necessary approvals of
     the Merger and this Agreement by its shareholders; and

               (iii) subject to the fiduciary duties of the Company Board,
     include in the Proxy Statement the recommendation of the Company Board that
     shareholders of the Company vote in favor of the approval of this
     Agreement.

          (b) The Company covenants that the Proxy Statement will comply in all
material respects with the provisions of applicable federal securities laws and,
on the date filed with the SEC and on the date first published, sent or given to
the Company's shareholders, shall not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary in order to make the statements made therein, in light of the
circumstances under which they were made, not misleading, except that no
representation is made by the Company with respect to information supplied by
ICS in writing for inclusion in the Proxy Statement.  Each of the Company, on
the one hand, and ICS, on the other hand, agree promptly to correct any
information provided by either of them for use in the Proxy Statement if and to
the extent that it shall have become false or misleading, and the Company
further agrees to take all steps necessary to cause the Proxy Statement as so
corrected to be filed with the SEC and to be disseminated to the holders of
Shares, in each case, as and to the extent required by applicable federal
securities laws.

          Section 5.14    Conveyance Taxes.  ICS and the Company shall cooperate
in the preparation, execution and filing of all returns, questionnaires,
applications or other documents regarding any real property transfer or gains,
sales, use, transfer, value-added, stock transfer and stamp taxes, any transfer,
recording, registration and other fees or any similar taxes which become payable
by the Company or any of its Subsidiaries in connection with the transactions
contemplated by this Agreement that are required or permitted to be filed on or
before the Effective Time.

          Section 5.15    Delisting.  Each of the parties agrees to cooperate
with each other in taking, or causing to be taken, all actions necessary to
delist the Common Shares from NASDAQ and to terminate registration under the
Exchange Act, provided that such delisting and termination shall not be
effective until after the Effective Time of the Merger.

          Section 5.16    Solvency Letters.  The Company Board or Special
Committee shall engage an independent appraisal firm to deliver a letter
addressed to the Company Board, as to the solvency of the Company and its
Subsidiaries on a consolidated basis after giving effect to the transactions
contemplated by this Agreement, including all financings contemplated hereby.

                                   ARTICLE 6
                    CONDITIONS TO CONSUMMATION OF THE MERGER

Company to consummate the Merger are subject to the satisfaction, at or before
the Effective Time, of each of the following conditions:

                                      -32-
<PAGE>
 
                (a) Shareholder Approval. The shareholders of the Company shall
have duly approved the transactions contemplated by this Agreement (the
"Shareholder Approval"), if required by applicable law.

                (b) Solvency Letters. The Company shall have received a solvency
letter, in form and substance and from an independent evaluation firm reasonably
satisfactory to it, as to the solvency of the Company and its Subsidiaries on a
consolidated basis after giving effect to the transactions contemplated by this
Agreement, including all financings contemplated hereby.

                (c) Orders and Injunctions. No order shall have been entered in
any action or proceeding before any United States federal or state court or
governmental agency or other United States regulatory or administrative agency
or commission (an "Order"), and no preliminary or permanent injunction by a
United States court of competent jurisdiction shall have been issued and remain
in effect (an "Injunction"), which, in either case, would have the effect of (i)
preventing consummation of the Merger, or (ii) imposing material limitations on
the ability of ICS effectively to acquire or hold the business of the Company
and its Subsidiaries taken as a whole; provided, however, that in order to
invoke this condition, ICS shall have used in its judgment, its commercially
reasonable efforts to prevent such Order or Injunction or ameliorate the effects
thereof.

                (d) Illegality. There shall not have been any United States
federal or state statute, rule or regulation enacted or promulgated after the
date of this Agreement that could in the reasonable judgment of ICS result in
any of the material adverse consequences referred to in paragraph (c) above.

                (e) HSR Act. Any waiting period (and any extension thereof)
under the HSR Act applicable to the Merger shall have expired or terminated.

          Section 6.2    Conditions to Obligations of ICS.  The obligations of
ICS to effect the Merger are further subject to the following conditions:

                (a) Representations and Warranties. The representations and
warranties of the Company set forth in this Agreement shall be true and correct
in the aggregate in all material respects, as of the date of this Agreement and
as of the Closing Date as though made on and as of the Closing Date. For
purposes of determining whether any representation or warranty is true and
correct, any requirement that a fact or event be or not be material or have or
not have a Material Adverse Effect on the Company (a "Materiality Qualifier")
shall be ignored. The condition in the first sentence of this Section 6.2(a)
shall be deemed satisfied only if the failure of the representations and
warranties of the Company to be true and correct in the aggregate (determined
without giving effect to any Materiality Qualifier) does not constitute a
Material Adverse Effect on the Company. ICS shall have received a certificate
signed on behalf of the Company by the Chairman of the Board and the chief
financial officer of the Company to the effect set forth in this paragraph.

                (b) Performance of Obligations of the Company. The Company shall
have performed the obligations required to be performed by it under this
Agreement in all material respects at or prior to the Closing Date, except for
such failures to perform as have not had or would 

                                      -33-
<PAGE>
 
not, individually or in the aggregate, have a Material Adverse Effect with
respect to the Company or materially adversely affect the ability of the Company
to consummate the transactions contemplated hereby.

                (c) Consents, Etc. ICS shall have received evidence, in form and
substance reasonably satisfactory to it, that all licenses, permits, consents,
approvals, authorizations, qualifications and orders of governmental authorities
and other third parties set forth in Section 3.3 of the Disclosure Schedule
shall have been obtained.

                (d) No Litigation. There shall not be pending by any
Governmental Entity any suit, action or proceeding (or by any other person any
suit, action or proceeding which has a reasonable likelihood of success), (i)
challenging or seeking to restrain or prohibit the consummation of the Merger or
any of the other transactions contemplated by this Agreement or seeking to
obtain from ICS or any of their affiliates any damages that are material to any
such party (ii) seeking to prohibit or limit the ownership or operation by the
Company or any of its Subsidiaries of any material portion of the business or
assets of the Company or any of its Subsidiaries, to dispose of or hold separate
any material portion of the business or assets of the Company or any of its
Subsidiaries, as a result of the Merger or any of the other transactions
contemplated by this Agreement or (iii) seeking to impose limitations on the
ability of ICS (or any shareholder of ICS), to acquire or hold, or exercise full
rights of ownership of, any Common Shares, including, without limitation, the
right to vote Common Shares on all matters properly presented to the
shareholders of the Company.

                (e) Financing. The Company shall have received the proceeds of
financing pursuant to the commitment letters set forth on Section 6.2(e) of the
Disclosure Schedule on terms and conditions set forth therein (or, as modified
in accordance with Section 5.3(c) hereof) and on such other terms and conditions
consistent therewith, or involving such other financing sources, as are
reasonably satisfactory to ICS in its sole discretion, in amounts sufficient to
consummate the transactions contemplated by this Agreement, including, without
limitation: (i) to pay, with respect to all Common Shares in the Merger, the
Merger Consideration pursuant to Section 2.1(b) hereof; (ii) to refinance the
outstanding indebtedness of the Company; (iii) to pay any fees and expenses in
connection with the transactions contemplated by this Agreement or the financing
thereof; and (iv) to provide for the working capital needs of the Company
following the Merger, including, without limitation, if applicable, letters of
credit.

          Section 6.3    Conditions to Obligation of the Company.  The
obligation of the Company to effect the Merger is further subject to the
following conditions:

                (a) Representations and Warranties.  The representations and
warranties of ICS set forth in this Agreement shall be true and correct in all
respects, in each case as of the date of this Agreement and as of the Closing
Date as though made on and as of the Closing Date.  The Company shall have
received certificates signed on behalf of ICS, respectively, by an authorized
officer of ICS, respectively, to the effect set forth in this paragraph.

                                      -34-
<PAGE>
 
                (b) Performance of Obligations of ICS. ICS shall have performed
the obligations required to be performed by it under this Agreement at or prior
to the Closing Date (except for such failures to perform as have not had or
could not reasonably be expected, either individually or in the aggregate, to
have a Material Adverse Effect with respect to ICS or adversely affect the
ability of ICS to consummate the transactions herein contemplated or perform its
obligations hereunder).

                                   ARTICLE 7
                        TERMINATION; AMENDMENTS; WAIVER

          Section 7.1    Termination.  This Agreement may be terminated and the
Merger contemplated hereby may be abandoned at any time prior to the Effective
Time, notwithstanding approval thereof by the shareholders of the Company:

               (a) by the mutual written consent of ICS and the Company, by
     action of their respective Boards of Directors;

               (b) by ICS or the Company if the Merger shall not have been
     consummated on or before May 31, 1999; provided, however, that neither ICS
     nor the Company may terminate this Agreement pursuant to this Section
     7.1(b) if such party shall have materially breached this Agreement;

               (c) by ICS or the Company if any court of competent jurisdiction
     in the United States or other United States Governmental Entity has issued
     an order, decree or ruling or taken any other action restraining, enjoining
     or otherwise prohibiting the Merger and such order, decree, ruling or other
     action shall have become final and nonappealable; provided, however, that
     the party seeking to terminate this Agreement shall have used its
     commercially reasonable efforts to remove or lift such order, decree,
     ruling or other action;

               (d) by the Company if, prior to the Effective Time, any person
     has made a bona fide proposal relating to an Acquisition Transaction, or
     has commenced a tender or exchange offer for the Common Shares, and the
     Company Board or Special Committee determines in good faith (i) after
     consultation with its financial advisors, that such transaction constitutes
     a Higher Offer and (ii) after consultation with counsel, that failure to
     approve such proposal and terminate this Agreement could reasonably be
     expected to result in a breach of fiduciary duties to shareholders
     (assuming for such purpose that fiduciary duties are owed only to
     shareholders), as they would exist in the absence of any limitations in
     this Agreement, of the Company Board to the Company's shareholders;
     provided, however, that, notwithstanding anything in this Agreement to the
     contrary, the termination of this Agreement by the Company in compliance
     with this Section 7.1(d) shall not be deemed to violate any other
     obligations of the Company under this Agreement, and, provided further,
     that the Company shall have notified ICS of its intent to terminate prior
     to the effective date of such termination;

                                      -35-
<PAGE>
 
               (e) by ICS, if the Company Board shall have (i) failed to
     recommend to the shareholders of the Company that they give the Shareholder
     Approval, (ii) withdrawn or modified in a manner adverse to ICS its
     approval or recommendation of this Agreement or the Merger, (iii) shall
     have approved or recommended an Acquisition Transaction, (iv) shall have
     resolved to effect any of the foregoing or (v) shall have otherwise taken
     steps to materially impede the Shareholder Approval; or

               (f) by either ICS or the Company, if the Shareholder Approval
     shall not have been obtained by reason of the failure to obtain the
     required vote upon a vote held at a duly held meeting of shareholders or at
     any adjournment or postponement thereof.

          Section 7.2    Effect of Termination.  In the event of the termination
of this Agreement pursuant to Section 7.1 hereof, this Agreement shall forthwith
become void and have no effect, without any liability on the part of any party
or its directors, officers or shareholders, other than the provisions of the
last sentence of Section 5.2 hereof and the provisions of this Section 7.2 and
Section 7.3 hereof, which shall survive any such termination.  Nothing contained
in this Section 7.2 shall relieve any party from liability for any breach of any
covenant of this Agreement or any breach of warranty or misrepresentation.

           Section 7.3   Fees and Expenses.

                (a) In the event that this Agreement is terminated for any
reason other than (i) on account of any of the conditions set forth in Section
6.1(c), 6.1(d), 6.1(e), 6.2(d), 6.3(a) or 6.3(b) hereof not being satisfied,
(ii) primarily as a result of material adverse changes in the economy or
industry occurring after the date hereof, or (iii) solely on account of ICS's
failure to obtain the financing described in Section 6.2(e) hereof, the Company
shall promptly reimburse ICS for all out-of-pocket expenses and fees (including,
without limitation, fees payable to all banks, investment banking firms and
other financial institutions, and their respective agents and counsel, and all
out-of-pocket fees and expenses, including bank commitment fees and expenses,
attorneys' and accountants' fees, and costs associated with financial printers,
experts and consultants to ICS and its affiliates, collectively referred to as
"Costs"), whether incurred prior to, on or after the date hereof, in connection
with the Merger and the consummation of all transactions contemplated by this
Agreement, and the financing thereof up to $3 million. Except as otherwise
specifically provided for herein, whether or not the Merger is consummated, all
costs and expenses incurred in connection with this Agreement and the
transactions contemplated by this Agreement shall be paid by the party incurring
such expenses.

                (b) In the event that this Agreement is terminated (i) pursuant
to Sections 7.1(d) or 7.1(f) hereof or by ICS pursuant to Section 7.1(b) hereof
based upon a material breach of this Agreement by the Company or by ICS pursuant
to Section 7.1(e) hereof, and (ii) within 12 months after the date of
termination the Company enters into a legally binding acquisition agreement for
a Business Combination (as defined herein) or a Business Combination is
consummated, the Company will, within three business days following the
consummation of such a Business Combination, pay to ICS in cash by wire transfer
in immediately available funds to an account designated by ICS a payment in an
amount equal to $6 million (the "Termination Fee"), 

                                      -36-
<PAGE>
 
provided that in no event shall more than one Termination Fee be payable by the
Company. For purposes of this Section 7.3, the term "Business Combination" means
(i) a merger, consolidation, share exchange, business combination or similar
transaction involving the Company as a result of which the shareholders of the
Company prior to such transaction in the aggregate cease to own at least a
majority of the voting securities of the entity surviving or resulting from such
transaction (or ultimate parent entity thereof), (ii) a sale, lease, exchange,
transfer or other disposition of more than 50% of the assets of the Company and
its Subsidiaries, taken as a whole, in a single transaction or a series of
related transactions, or (iii) the acquisition, by a person (other than ICS or
any affiliate thereof) or group (as such term is defined under Section 13(d) of
the Exchange Act and the rules and regulation thereunder) of beneficial
ownership (as defined in Rule 13d-3 under the Exchange Act) of more than 25% of
the Common Shares whether by tender or exchange offer or otherwise.

                (c) The prevailing party in any legal action undertaken to
enforce this Agreement or any provision hereof shall be entitled to recover from
the other party the costs and expenses (including attorneys' and expert witness
fees) incurred in connection with such action.

          Section 7.4    Amendment.  This Agreement may be amended by the
Company and ICS at any time before or after any approval of this Agreement by
the shareholders of the Company but, after any such approval, no amendment shall
be made which decreases the Merger Consideration or which the Company Board or
Special Committee determines adversely affects the rights of the Company's
shareholders hereunder without the approval of such shareholders.  This
Agreement may not be amended except by an instrument in writing signed on behalf
of all the parties.

          Section 7.5    Extension; Waiver.  At any time prior to the Effective
Time, ICS, on the one hand, and the Company, on the other hand, may (i) extend
the time for the performance of any of the obligations or other acts of the
other, (ii) waive any inaccuracies in the representations and warranties
contained herein of the other or in any document, certificate or writing
delivered pursuant hereto by the other or (iii) waive compliance by the other
with any of the agreements or conditions. Any agreement on the part of any party
to any such extension or waiver shall be valid only if set forth in an
instrument in writing signed on behalf of such party.

                                   ARTICLE 8
                                 MISCELLANEOUS

          Section 8.1    Non-Survival of Representations and Warranties.  The
representations and warranties made in this Agreement shall not survive beyond
the Effective Time.

          Section 8.2   Entire Agreement; Assignment.

                (a) This Agreement (including the documents and  the instruments
referred to herein) and the Confidentiality Agreement constitute the entire
agreement and supersede all prior agreements and understandings, both written
and oral, among the parties with respect to the subject matter hereof and
thereof.

                                      -37-
<PAGE>
 
                (b) Neither this Agreement nor any of the rights, interests or
obligations hereunder will be assigned by any of the parties hereto (whether by
operation of law or otherwise) without the prior written consent of the other
party (except that ICS may assign its rights, interest and obligations to any
affiliate or Subsidiary of ICS without the consent of the Company, provided that
no such assignment shall relieve ICS of any liability for any breach by such
assignee).  Subject to the preceding sentence, this Agreement will be binding
upon, inure to the benefit of and be enforceable by the parties and their
respective successors and assigns.

          Section 8.3    Validity.  The invalidity or unenforceability of any
provision of this Agreement shall not affect the validity or enforceability of
any other provision of this Agreement, each of which shall remain in full force
and effect.

          Section 8.4    Notices.  All notices, requests, claims, demands and

FOR IMMEDIATE RELEASE



             INTEGRATED CIRCUIT SYSTEMS AGREES TO BE ACQUIRED FOR
                           $21.25 PER SHARE IN CASH


VALLEY FORGE, PA - January 20, 1999 - Integrated Circuit Systems, Inc. (Nasdaq:
ICST) today announced that it has entered into a definitive agreement under
which an investor group comprised of its senior management together with
affiliates of Bain Capital Inc. and Bear, Stearns & Co. Inc. will acquire all of
the outstanding shares of ICS at a cash price of $21.25 per share.

The transaction was unanimously approved yesterday by Integrated Circuit
Systems' Board of Directors, acting upon the recommendation of a Special
Committee of the Board comprised of two independent Directors who are not part
of the investor group. In reaching its decision, the Special Committee was
advised by its financial advisor, Pennsylvania Merchant Group, which rendered a
written opinion that the $21.25 acquisition price is fair to the unaffiliated
holders of common stock of Integrated Circuit Systems from a financial point of
view.

It is expected that the proposed acquisition will be voted on by ICS'
shareholders at a Special Meeting of Shareholders to be held in the Company's
fiscal fourth quarter.  In addition, completion of the merger is subject to the
receipt of funding by the investor group under existing financing commitments
and is subject to other customary conditions, including the receipt of certain
regulatory approvals.

The Company also announced that it has entered into a definitive agreement to
sell intellectual property and engineering hardware and software related to its
data communications business to 3Com Corporation for approximately $16 million
in cash.  The assets sold include customer-owned tooling (COT) technology,
patents, design databases and software programs.  The transaction is subject to
the satisfaction of customary conditions and is expected to close by the end of
February 1999.  Under the agreement, Integrated Circuit Systems will have
certain licensing and technical support rights, and will continue to sell and
support its existing and prospective fast ethernet transceiver product family to
current and new customers.

Rudolf Gassner, ICS' Chairman of the Board, who is not a member of the investor
group, said, "After careful review, and with the assistance of our financial
advisor, the Board of Directors has concluded that these transactions are in the
best interests of ICS' shareholders."

Integrated Circuit Systems Inc. is a manufacturer of integrated circuit products
focusing on the design and marketing of mixed signal integrated circuits for
frequency timing, multimedia and data communications applications.  The Company
is headquartered in Valley Forge, Pennsylvania with a major facility in San
