 Senior Secured Credit Facilities and Mezzanine Facility Loan Commitment Letter
 ------------------------------------------------------------------------------

Ladies and Gentlemen:

          You have advised Credit Suisse First Boston ("CSFB") that Bain
Capital,  Inc. and  Bear,  Stearns  & Co.  Inc.  (the "Investors"),  propose  to
create a newly formed entity reasonably satisfactory to CSFB, which will merge
(the "Merger") into Integrated Circuit Systems, Inc. (the "Company") in a
transaction (the "Recapitalization") that will provide for recapitalization
accounting treatment.  We understand that the Recapitalization will be
accomplished through the Merger, the redemption of certain capital of Company
from existing shareholders for an aggregate redemption price of $259.2 million,
adjusted for cash on hand, and the "rollover" of certain capital stock of
Company by certain existing shareholders of Company. You have further advised us
that in connection with the Recapitalization (i) the Investors and certain
management investors and existing shareholders will make or cause to be made an
equity contribution of approximately $50.0 million (the "Equity Contribution")
to the Company (with up to approximately $10 million of such Equity Contribution
to be made by such management investors and such existing shareholders), (ii)
the Company will obtain senior secured credit facilities (the "Senior
Facilities") in an aggregate principal amount of up to $145 million (as more
fully described in the Summary of Principal Terms and Conditions attached hereto
as Exhibit A (the "Senior Term Sheet"), and (iii) the Company will obtain senior
subordinated mezzanine loan 

<PAGE>
 
financing (the "Mezzanine Facility") of $47.5 million, (the Recapitalization,
the Merger and the transactions referred to in the immediately preceding clauses
(i) through (iii) are collectively referred to herein as the "Transactions").
The approximate sources and uses of the funds necessary to consummate the
Transactions are set forth on Annex II to the Senior Term Sheet.

          You have requested that CSFB (i) agree to structure, arrange and
syndicate the Senior Facilities, (ii) commit to provide the Senior Facilities
and to serve as advisor, arranger, administrative agent and collateral agent
therefor, (iii) agree to structure, arrange and syndicate the Mezzanine Facility
(together with the Senior Facilities, the "Facilities") and (iv) commit to
provide the Mezzanine Facility and to serve as advisor, arranger and
administrative agent therefor.  CSFB is pleased to advise you of (i) its
willingness to act as exclusive advisor, arranger, administrative agent and
collateral agent for the Senior Facilities, (ii) its commitment to provide the
entire amount of the Senior Facilities upon the terms and subject to the
conditions set forth or referred to in this commitment letter and the exhibits
hereto (the "Commitment Letter") (including, without limitation, the conditions
set forth in Exhibit C attached hereto) and in the Senior Term Sheet, (iii) its
willingness to act as exclusive advisor, arranger and administrative agent for
the Mezzanine Facility and (iv) its commitment to provide the entire amount of
the Mezzanine Facility upon the terms and subject to the conditions set forth or
referred to herein (including, without limitation, the conditions set forth in
Exhibit C attached hereto) and in the Summary of Principal Terms and Conditions
attached as Exhibit B hereto (the "Mezzanine Term Street"; together with the
Senior Term Sheet, the "Term Sheets").

          CSFB reserves the right and intends, prior to or after the execution
of the definitive documentation with respect to the Facilities (the "Facilities
Documents"), to syndicate all or a portion of its commitments to one or more
financial institutions (such financial institutions, together with CSFB, the
"Lenders") identified by CSFB in consultation with, and reasonably acceptable
to, you, which Lenders will become parties to the Facilities Documents. It is
agreed that CSFB will act as the sole administrative agent and advisor for, and
sole arranger and syndication manager of, the Facilities and that no additional
agents or co-agents or co-arrangers will be appointed without the prior written
consent of CSFB.

          CSFB also reserves the right to require Company to issue, in lieu of
the Mezzanine Facility (and, at the option of CSFB in lieu of all or a portion
of the Senior Facilities) high-yield debt securities (the "Alternative
Securities"); provided that such issuances shall be made in consultation with,
              --------                                                        
and with the consent of, the Investors and Company, not to be unreasonably
withheld.

                                       2

          In addition, CSFB also reserves the right to employ the services of
Credit Suisse First Boston Corporation ("CSFBC") in providing services
incidental to the provision of the Mezzanine Facility or the Alternative
Securities and any resale or refinancing of the Mezzanine Loans (as defined in
the Mezzanine Term Sheet), and you agree that, solely in connection with the
provision of such services, CSFB and CSFBC may share with each other any
confidential or other information relating to the Investors and the Company and
its subsidiaries and their respective affiliates as from time to time they may
possess.

          CSFB will manage all aspects of the syndication, including decisions
as to the selection of institutions to be approached and when they will be
approached, when their commitments will be accepted, which institutions
identified by us in consultation with, and reasonably acceptable to, you, will
participate in the allocations of the commitments among the Lenders and the
amount and distribution of fees among the Lenders.  The Investors understand
that the Senior Facilities and the Mezzanine Facility will be separately
syndicated.  You agree to assist CSFB in forming any such syndicate and to
provide the potential Lenders, promptly upon request, with all information
reasonably requested by them to complete successfully the syndication, including
but not limited to (a) an information package, including a Confidential
Information Memorandum for each of the Facilities and other marketing materials
for delivery to potential Lenders and participants, and (b) all information and
projections prepared by you or your advisors relating to the Transactions. You
also agree to participate in, and to make appropriate senior officers and
representatives of the Investors, available (and to use commercially reasonable
efforts to make senior officers and representatives of Company available) to
participate in, informational meetings for potential Lenders and participants at
such times and places as CSFB may reasonably request and to use commercially
reasonable efforts to ensure that CSFB's syndication efforts materially benefit
from the Investors and the Company's existing lending relationships.

          The Investors represent and warrant and covenant that, to the best of
their knowledge:

          (a) all written information (other than financial projections) which
     has been or is hereafter furnished to CSFB by you or any of your
     representatives in connection with the Transactions is complete and correct
     as of the date thereof in all material respects and does not contain any
     untrue statement of a material fact or omit to state a material fact
     necessary in order to make the statements contained therein not misleading
     in light of the circumstances under which such statements were or are made;
     and

                                       3
<PAGE>
 
          (b) all financial projections that have been or are hereafter prepared
     by you or on your behalf and made available to CSFB have been or will be
     prepared in good faith based upon what you believe to be reasonable assump
     tions (it being understood that such projections are subject to significant
     uncertainties and contingencies, many of which are beyond your, or the
     Company's, control and that no assurance can be given that the projections
     will be realized).

The Investors agree to supplement the information and projections referred to in
clauses (a) and (b) above from time to time until completion of the syndication
so that the representations and warranties in the preceding sentence remain
correct without regard to when such information and projections were furnished.
In arranging and syndicating the Facilities, CSFB will be entitled to use and
rely on such information and projections without independent verification
thereof.

          In connection with the syndication of the Facilities, CSFB may, in its
discretion, allocate to other Lenders portions of any fees payable to CSFB in
connection with the Facilities. You agree that neither you nor the Company nor
any of your or its affiliates will pay to any Lender any compensation or titles
of any kind for its participation in the Facilities except as expressly provided
for in this letter or in the fee letter dated the date hereof between you and
CSFB (the "Fee Letter").

          The Investors agree, jointly and severally, to (or to cause Company
to) reimburse CSFB and its affiliates, upon request made from time to time, for
their reasonable out-of-pocket fees and expenses incurred in connection with the
preparation, execution and delivery of this letter, the Fee Letter, the Warrant
Letter (as defined below) and the Facilities Documents and the activities
thereunder or contemplated thereby, including without limitation syndication
expenses (other than fees allocated in accordance with the preceding paragraph)
and the reasonable fees and expenses of Skadden, Arps, Slate, Meagher & Flom LLP
and such other outside counsel and advisors to CSFB and its affiliates approved
by you (such approval not to be unreason  ably withheld) payable on the earlier
of (i) the date the commitment of CSFB hereunder is terminated or (ii) the
Closing Date.

                                       4

          The Investors also agree, jointly and severally, to (or to cause the
Company to) indemnify and hold harmless CSFB and each other Lender, their
respective affiliates and each of their respective directors, officers,
employees, agents and advisors (each, an "Indemnified Party"), from and against
any and all claims, damages, liabilities (including securities law liabilities),
losses and expenses, including reasonable fees, expenses and disbursements of
counsel, which may be incurred by or asserted against an Indemnified Party in
connection with CSFB's or any Lender's commitment or participation in the
transactions contemplated by this letter, the Facilities or any related matter
or any investigation, litigation or proceeding in connection therewith and
whether or not the Recapitalization is consummated or the Facilities are drawn

                        deemed to be a drawing under the Revolving Facility.

                        to the customary procedures of the Issuing Bank.

                            determination by such Lender that such exchange
                            is prohibited by law, rule, regulation or order
                            applicable to such Lender or that such exchange
                            would reasonably be expected to have an adverse
                            effect on such Lender or would otherwise be
                            inconsistent with such Lender's business

                            amounts as will result in holders receiving such
                            amounts as they would have received had no such
                            withholding or reduction been required.  In

                            agree, on customary terms, to take such actions to
                            mitigate withholding taxes as are not adverse to it
                            in its reasonable discretion.

                            CONDITIONS\1\
                            -------------- 



          CSFB has conducted its due diligence with respect to the Facilities
and the Transactions and is pleased to inform you that it is satisfied with the
results thereof; however, the commitments of CSFB pursuant to the Letter are
subject to the condition that after the date of the Letter nothing becomes known
to CSFB that is inconsistent in a material and adverse manner with anything
disclosed to CSFB prior to the date of the Letter or anything previously
obtained by CSFB during such due diligence.

          In addition to the foregoing, the commitments of CSFB pursuant to the
Letter are also subject to the following conditions:

         (1)  the preparation, execution and delivery of definitive
         documentation in connection with the Facilities reasonably satisfactory
         to CSFB, and the satisfaction (as reasonably determined by CSFB) of
         customary closing conditions for transactions similar to the Senior
         Facilities and the Mezzanine Facility, as applicable;

         (2)  CSFB and the Lenders shall be reasonably satisfied as of the
         Closing Date with the material terms and conditions of the
         Recapitalization Agreement and each other agreement entered into in
         connection with the Transactions and with all legal, tax and accounting
         matters (it being understood that a failure to obtain recapitalization
         accounting treatment with respect to the Transactions will not give
         rise to rights on the part of CSFB hereunder) relating to the
         Transactions that would reasonably be expected to have a Material
         Adverse Effect, including without limitation, any such matters
         pertaining to pending or potential litigation with respect to the
         Transactions and requisite stockholder or governmental consents or
         approvals; provided, however, that the failure of the Merger and
         related transactions to be eligible for recapitalization accounting
         shall not be considered a failure to satisfy any of the conditions to
         the commitments of CSFB stated herein;

         (3)  after giving effect to the Transactions and the other transactions
         contemplated by the Letter, neither any Loan Party nor any of their
         subsidiaries

- ---------------------------
\1\ All capitalized terms used but not defined herein have the meanings given to
them in the Commitment Letter to which this Exhibit C is attached.

shall have outstanding any indebtedness or preferred stock other than (a) the
loans under the Senior Facilities, (b) the Alternative Securities or the loans
under the Mezzanine Facility, and (c) other indebtedness or preferred stock to
be agreed upon;

     (4)  there shall not have occurred and be continuing (a) any general
     suspension of trading in securities on the New York or American Stock
     Exchange or in the NASDAQ National Market System (other than circuit
     breakers), (b) the declaration of a banking moratorium or any suspension of
     payments in respect of banks in the United States, or (c) any other
     material adverse change in banking or capital market conditions that has
     had a material adverse effect on the syndication of leveraged bank credit
     facilities or the consummation of high yield offerings, as the case may be,
     that CSFB reasonably determines makes it impracticable to consummate the
     Alternative Securities Offering or successfully syndicate the Senior
     Facilities or the Mezzanine Facility;

     (5)  CSFB's satisfaction that, immediately prior to and during the
     marketing period for either the syndication of (a) the Senior Facilities or
     (b) the Mezzanine Facility, there shall be no competing issues of debt
     securities or commercial bank facilities (other than the Senior Facilities
     and the Mezzanine Facility, or other permitted indebtedness thereunder) of
     any Loan Party or any of their affiliates;

     (6)  the receipt by CSFB and, if applicable, the Lenders, on or before the
     closing of the Transactions, of financial statements of the Company
     (including notes thereto), consisting of (a) audited and pro forma balance
     sheets as of the end of each period in the 3 fiscal-year period most
     recently ended, (b) audited and pro forma statements of operations and cash
     flows for each period in the 3 fiscal-year period ending June 30, 1998, (c)
     consolidated financial statements for each period in the 3 fiscal-year
     period most recently ending and supporting documentation satisfactory to
     CSFB, (d) comparable unaudited historical and pro forma interim financial
     statements covering all quarterly or other appropriate periods subsequent
     to the fiscal year most recently ended, and (e) such final projections in
     respect of the Loan Parties and their respective subsidiaries as CSFB may
     reasonably request; and all such financial statements, historical or pro
     forma, delivered pursuant to this paragraph (vi) shall be in compliance
     with the requirements of Regulation S-X for a public 



                                      C-2

     offering registered under the Securities Act of 1933, and all financial
     statements and projections referred to in this paragraph (vi) shall not be
     materially inconsistent with financial statements, projections and
     estimates previously provided to CSFB and, if applicable, the Lenders;

     (7)  payment of fees and expenses;

     (8)  since June 27, 1998, there shall not have occurred or become known to
     CSFB any event or events, adverse condition or change that, individually or
     in the aggregate, would reasonably be expected to have a Material Adverse
     Effect; and

     (9)  the Closing Date shall occur on or before June 30, 1999.

          In the event that anything arising under the first paragraph of  this
Exhibit C comes to the attention of CSFB or that any of the other conditions set
forth above or in the Facilities Documents are not satisfied, CSFB reserves the
right, in its sole discretion, to either (x) suggest alternative financing
amounts or structures that ensure adequate protection for CSFB and the Lenders
(in consultation with, and as approved by, the Investors and the Company) or (y)
decline to participate in the proposed financings.

          As used herein, a "Material Adverse Effect" shall mean the result of
one or more events, changes or effects which, individually or in the aggregate,
would reasonably be expected to have a material adverse effect on (i) the
business, results of operations, financial condition or prospects of the Company
and its subsidiaries, in each case, taken as a whole, or (ii) the validity or
enforceability of any of the documents entered into in connection with the
Transactions or the other transactions contemplated by the Letter or the rights,
remedies and benefits available to the parties thereunder.

   Dear Shareholder:
 
   You are cordially invited to attend the Special Meeting of the Shareholders
of Integrated Circuit Systems, Inc. to be held on    , 1999, beginning at
10:00 a.m. (local time), at the offices of the Company, 2435 Boulevard of the
Generals, Norristown, Pennsylvania.
 
   At this important meeting, you will be asked to consider and vote upon a
proposed merger between the Company and ICS Merger Corp., a corporation newly-
formed by Bain Capital, Inc. and Bear, Stearns & Co. Inc. In the proposed
merger, (i) the Company will be recapitalized and investment funds associated
with Bain Capital and Bear, Stearns, together with certain members of the
Company's management, will own substantially all of the outstanding common
stock of the Company and (ii) the existing shareholders of the Company (other
than certain members of management) will be entitled to receive $21.25 in cash
for each share of their common stock.
 
   Consummation of the merger is subject to a number of conditions, including
the Company obtaining the necessary financing under existing commitments to
complete the merger. Accordingly, even if the shareholders approve the merger,
there can be no assurance that the merger will be consummated.
 
   The merger agreement with ICS Merger Corp. has been unanimously approved by
your Board of Directors, acting on the unanimous recommendation of an
independent Special Committee of the Board of Directors. The Board of
Directors and Special Committee received the opinion of their investment
banker, Pennsylvania Merchant Group, dated January 19, 1999, to the effect
that the consideration to be received by the Company's unaffiliated
shareholders in the merger, as of such date, was fair to such shareholders
from a financial point of view. The Board of Directors has concluded that the
proposed merger is in the best interests of the Company's shareholders and,
therefore, THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE TO
APPROVE AND ADOPT THE MERGER AGREEMENT.
 
   The attached Notice of Special Meeting and Proxy Statement explain the
proposed merger and provide specific information concerning the Special
Meeting. Please read these materials carefully.
 
   Whether or not you plan to attend the Special Meeting, we urge you to
complete, sign and promptly return the enclosed proxy card to assure that your
shares will be voted at the meeting. This will not prevent you from voting
your shares in person if you subsequently choose to attend. As soon as
practicable after the effectiveness of the merger, you will receive
instructions for surrendering your share certificates in exchange for $21.25
in cash and a letter of transmittal to be used for this purpose. You should
not submit your share certificates for exchange until you have received such
instructions and the letter of transmittal.
 
   The merger is an important step for the Company and its shareholders. THE
MERGER CANNOT BE COMPLETED UNLESS THE COMPANY'S SHAREHOLDERS APPROVE AND ADOPT
THE MERGER AGREEMENT.
 
   On behalf of the Board of Directors, I thank you for your support and urge
you to vote IN FAVOR OF the merger.
 
                                                      Very truly yours,
 
                                                      /s/ Rudolf S. Gassner

   entitled to receive $21.25 in cash, without interest, for each share of
   their common stock of the Company.
 
Q: Why is the Board of Directors recommending that I vote to approve and adopt
   the Merger Agreement?
 
A: In the opinion of the Special Committee and the Board of Directors, the
   terms and provisions of the Merger Agreement and the Merger are fair to and
   in the best interests of the Company and its shareholders. To review the
   background of and reasons for the Merger, see pages 14 to 19.
 
Q: How many votes are required to approve and adopt the Merger Agreement?
 
A: A majority of the votes cast by all holders of outstanding shares of common
   stock of the Company as of the record date is required to approve and adopt
   the Merger Agreement and the transactions contemplated thereby, including
   the Merger.
 
Q: If I am a shareholder, what do I need to do now?
 
A: After you read and consider carefully the information contained in this
   Proxy Statement, please fill out, sign and date your proxy card and mail
   your signed proxy card in the enclosed return envelope as soon as possible
   so that your shares may be represented at the Special Meeting.
 
Q: What rights do I have if I oppose the Merger?
 
A: Shareholders who oppose the Merger may dissent from the Merger and seek to
   receive the fair value of their shares but only if they comply with the
   procedures of Pennsylvania law explained on page 39.
 
Q: If my shares are held in "street name" by my broker, will my broker vote my
   shares for me?
   
A: Yes, if you provide instructions to your broker on how to vote. You should
   fill out, sign, date and return the proxy card and otherwise follow the
   directions provided by your broker regarding how to instruct your broker to
   vote your shares.     
 
Q: Can I change my vote or revoke my proxy after I have mailed my signed proxy
   card?
   
A: Yes, you can change your vote at any time before your proxy is voted at the
   Special Meeting. You can do this in one of three ways. First, you can send a
   written notice stating that you would like to revoke your proxy. Second, you
   can complete and submit a new proxy card. If you choose either of these
   methods, you must timely submit your notice of revocation or your new proxy
   card to the Company. Third, you can attend the Special Meeting and vote in
   person. Simply attending a meeting, however, will not revoke your proxy. If
   you have instructed a broker to vote your shares, you must follow directions
   received from your broker to change your vote.     
 
Q: Should I send in my share certificates now?
 
A: No. Shortly after the Merger, you will receive a letter of transmittal with
   instructions informing you how to send in your stock certificates to the
   Company's paying agent.
 
Q: When do you expect the Merger to be completed?
 
A: We are working towards completing the Merger as soon as possible. For the
   Merger to occur, it must be approved by the Company's shareholders. If the
   shareholders approve the Merger, we expect to complete the Merger on or
   about       , 1999.

Q: What are the tax considerations of the Merger?
 
A: The receipt of cash by a shareholder in exchange for the Company's common
   stock in the Merger or the exercise of dissenters rights will, in each case,
   constitute a taxable transaction for federal income tax purposes and may
   also be a taxable transaction under state, local and foreign tax laws. In
   general, a shareholder will recognize gain or loss equal to the difference
   between $21.25 per share and such shareholder's adjusted tax basis in the
   shares exchanged. To review the tax considerations of the Merger in greater
   detail, see page 32.

   This summary highlights selected information from this Proxy Statement and
may not contain all of the information that is important to you. To understand
the Merger fully, you should read carefully this entire Proxy Statement
(including the information incorporated herein by reference) and the

Parties to the Merger
 
   The Company. The Company is an industry leader in the design, development
and marketing of mixed signal (analog and digital) integrated circuits ("ICs")
called frequency timing generators ("FTGs"). FTGs provide the various timing
signals or "clocks" necessary to synchronize high performance electronic
equipment. Initially, the Company's FTGs were utilized in video graphic
applications in personal computers, but uses have since expanded to include
motherboards and PC peripheral devices such as hard drives, audio cards and
laser printers as well as other non-PC applications. The Company also sells
customized mixed-signal ICs to meet the specific requirements of customer
applications when off-the-shelf solutions are technically inadequate. These
customized ICs are typically sold pursuant to development and product contracts
which generally provide for partial reimbursement of research costs and a
minimum purchase commitment by the customer. The Company also markets
transceiver chipsets for data communications applications.
 
   The Company's principal executive offices are located at 2435 Boulevard of
the Generals, Norristown, Pennsylvania, 19403, and its telephone number is

businesses in partnership with exceptional management teams and improve the
long-term value of those businesses. Bain Capital's principal executive offices
are located at Two Copley Place, Boston, Massachusetts 02116, and its telephone

The Special Meeting
 
   Place and Purpose. The Special Meeting of the shareholders of the Company
will be held at the offices of the Company, 2435 Boulevard of the Generals,
Norristown, Pennsylvania, on       , 1999 at
 
                                       3
<PAGE>
 
10:00 A.M., local time. At the Special Meeting, the Company's shareholders will
be asked to consider and vote upon the approval and adoption of the Merger
Agreement attached hereto as Appendix A.
   
   Record Date; Quorum. Only shareholders of record of the Company at the close
of business on April 2, 1999 (the "Record Date") will be entitled to notice of,
and to vote at, the Special Meeting. On the Record Date, there were
[12,166,450] shares of the Company's common stock outstanding. Except as noted
below, each holder of shares of the Company's common stock is entitled to one
vote for each such share so held, exercisable in person or by properly executed
and delivered proxy, at the Special Meeting. The presence of the holders of at
least a majority of the shares of the Company's common stock outstanding on the
Record Date and entitled to vote on the Merger Agreement, whether present in
person or by properly executed and delivered proxy, will constitute a quorum
for purposes of consideration of and action on the Merger Agreement.
Abstentions will be taken into account, and broker non-votes will not be taken
into account, in determining the presence of a quorum.     
 
   Vote Required. The affirmative vote of a majority of the votes cast at the
Special Meeting by all holders of record as of the Record Date is necessary to
approve and adopt the Merger Agreement. Where shareholders have appropriately
specified how their proxies are to be voted, they will be voted accordingly.
Abstentions and broker non-votes will not count for or against the Merger at
the Special Meeting.
 
   The Merger Agreement provides that certain shares held by members of the
Management Group will be converted into shares of the surviving corporation in
the Merger while all other outstanding shares will be converted into the right
to receive $21.25 in cash, without interest. Under Section 1906 of the Business
Corporation Law of Pennsylvania ("PBCL"), such disparate treatment is permitted
if approved by a majority of votes cast by all shareholders entitled to vote on
the Merger Agreement. Approval by shareholders of the Merger Agreement will
also constitute approval of such treatment.
 
   Security Ownership of Management. As of the Record Date, directors and
executive officers of the Company owned an aggregate of [421,282] shares of
common stock (approximately 3.0% of the outstanding common stock). The
directors and executive officers of the Company have indicated that they intend
to vote their shares of common stock in favor of the approval and adoption of
the Merger Agreement. See "Beneficial Ownership of Common Stock."
 
The Merger
 
   Effective Time of the Merger. It is currently contemplated that the Merger
will be consummated as soon as practicable after the Special Meeting and
satisfaction of all closing conditions under the Merger Agreement (including
receipt of financing under existing commitments). The Merger will be effective
upon the filing of Articles of Merger with the Department of State of the
Commonwealth of Pennsylvania (the "Effective Time").
 
   Consequences of the Merger. Pursuant to the Merger, Merger Corp. will be
merged into the Company, and the Company will be the surviving corporation (the
"Surviving Corporation"). Upon completion of the Merger, each share of the
Company's common stock (except for certain shares held by members of the
Management Group and shares held by shareholders who perfect their appraisal
rights) will be converted into the right to receive $21.25 in cash, without
interest (the "Merger Consideration"). Certain of the shares of the Company's
common stock held by members of the Management Group will be converted into
shares of the Surviving Corporation in the Merger (the "Converted Shares").
Shares of the Company's common stock held by shareholders who perfect their
appraisal rights under the PBCL ("Dissenting Shares" and, together with the
Converted Shares, the "Unconverted Shares") will not be converted into Merger
Consideration upon completion of the Merger.
 
   As a result of the Merger, the entire equity interest in the Company will be
owned by investment funds associated with Bain Capital and Bear Stearns (the
"Equity Investors"), the Management Group and certain other investors
(collectively, the "Investors"). The shareholders of the Company (other than
members of the
 
                                       4
<PAGE>
 
Management Group) will no longer have any interest in, and will not be
shareholders of the Company, and therefore will not participate in its future
earnings and growth. Instead, each such holder of the Company's common stock
will have the right to receive $21.25 in cash, without interest, for each share
held (other than the Unconverted Shares). Following the Merger, the Investors
will have the opportunity to benefit from any earnings and growth of the
Company, and will bear the risk of any decrease in the Company's value.
Following the Merger, the Company's common stock will no longer be traded on
the Nasdaq National Market, price quotations will no longer be available and
the registration of the Company's common stock under the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), will be terminated. After such
registration is terminated, the Company will no longer be required to file
periodic reports with the Commission.
 
Recommendation of the Special Committee and the Company's Board of Directors
   
   Because of the conflict of interests of Henry I. Boreen, a member of the
Board of Directors of the Company who is a member of the Management Group, the
Board established a special committee (the "Special Committee") for the purpose
of negotiating the price and other terms of the transactions with the Equity
Investors and evaluating the fairness of the Merger, the Merger Agreement and
the transactions contemplated thereby. The Special Committee is composed solely
of directors unaffiliated with any members of the Management Group.     
 
   The Special Committee and the Company's Board of Directors have each
determined that the terms of the Merger Agreement, which were established
through arm's-length negotiations with the Equity Investors, and the
transactions contemplated thereby, including the Merger, are fair to, and in
the best interests of, the Company and its shareholders. ACCORDINGLY, THE
SPECIAL COMMITTEE AND THE COMPANY'S BOARD OF DIRECTORS HAVE UNANIMOUSLY
APPROVED THE MERGER AGREEMENT AND UNANIMOUSLY RECOMMEND THAT THE COMPANY'S
SHAREHOLDERS VOTE FOR APPROVAL AND ADOPTION OF THE MERGER AGREEMENT.
 
Opinion of Financial Advisor
   
   Pennsylvania Merchant Group ("PMG") has delivered its written opinion to the
Special Committee and the Company's Board of Directors that, as of January 19,
1999, the Merger Consideration was fair, from a financial point of view, to the
Company's unaffiliated shareholders. PMG will be paid a fee upon consummation
of the Merger. See "Special Factors--Opinion of Financial Advisor."     
   
   PMG is a full service securities brokerage and investment banking firm. PMG
is a registered broker-dealer and investment advisor with the Commission and a
member firm of the NASD. PMG's principal office is located in the Philadelphia
area.     
   
   A copy of PMG's opinion, setting forth the assumptions made, procedures
followed, matters considered, limitations on and scope of the review by PMG, is
attached as Appendix B to this Proxy Statement. The Company's shareholders are
encouraged to read such opinion in its entirety. See "Special Factors--Opinion
of Financial Advisor."     
 
Conflicts of Interest
   
   In considering the recommendations of the Special Committee and the
Company's Board of Directors, the Company's shareholders should be aware that
certain members of the Management Group and of the Company's Board of Directors
have interests in the Merger that are in addition to the interests of the
Company shareholders generally and which create conflicts of interest. See
"Special Factors--Conflicts of Interest" and "The Merger Agreement--
Indemnification."

Federal Income Tax Consequences
 
   The receipt of cash by a shareholder in exchange for his or her shares of
the Company's common stock pursuant to the Merger or the exercise of dissenters
rights will, in each case, constitute a taxable transaction to such shareholder
for federal income tax purposes and may also be a taxable transaction under
applicable state, local and foreign tax laws. In general, a shareholder will
recognize gain or loss equal to the difference between $21.25 per share and
such shareholder's adjusted tax basis in the shares exchanged.
 
   All shareholders should read carefully the discussion in "The Merger--
Federal Income Tax Consequences" and other sections of this Proxy Statement.
They are urged to consult their own tax advisors as to the specific
consequences to them of the Merger under federal, state, local and any other
applicable tax laws.
       
       
Rights of Dissenting Shareholders
 
   Pursuant to the Merger Agreement and the PBCL, a shareholder of record of
the Company will have dissenters rights in connection with the Merger under
Sections 1571 through 1580 of Subchapter 15D Section 1906 and Section 1930 of
the PBCL and may object to the Merger Agreement and demand in writing that the
Company pay the fair value of their common stock. Sections 1571 through 1580 of
Subchapter 15D, Section 1906 and Section 1930 of the PBCL are included in this
Proxy Statement as Appendix C.
 
   If any holders of common stock properly exercise dissenters rights of
appraisal in connection with the Merger under Subchapter 15D of the PBCL, any
shares held by such holders will not be converted into the right to receive
$21.25 per share, but instead will be converted into the right to receive the
"fair value" of such shares pursuant to Subchapter D of Chapter 15 of the PBCL.
See "Appraisal Rights of Dissenting Shareholders."
 
Financing of the Merger
   
   The total amount of funds necessary to fund the Merger and related
transactions is expected to be approximately $293.4 million. These funds are
expected to come from the following sources: (i) an equity investment made by
the Equity Investors and certain other investors of approximately $40.0
million, (ii) an equity investment on the part of the Management Group of
approximately $10.0 million, consisting primarily of the Converted Shares
(valued at $21.25 per share) and certain existing options to purchase common
stock of the Company currently held by members of the Management Group (the
"Converted Options") which will be converted into options to purchase shares of
common stock of the Surviving Corporation (valued at the equity value of such
options, i.e. the difference between $21.25 and the exercise prices of such
options), (iii) cash of the Company on-hand at the Effective Time of
approximately $60.0 million and (iv) borrowings by the Company totaling
approximately $183.4 million under a senior secured credit facility and a
mezzanine loan facility.     
 
   The Equity Investors have received a financing commitment letter from Credit
Suisse First Boston ("CSFB") to provide the senior secured credit facility and
a financing commitment letter from CSFB and The Bear Stearns Companies Inc. to
provide the mezzanine loan facility. See "The Merger--Financing."
 
The Merger Agreement
 
   Conditions of the Merger. Each party's obligation to effect the Merger is
subject to the satisfaction of a number of conditions, most of which may be
waived. The most significant conditions to consummating the Merger include:
 
  .  obtaining the affirmative vote of a majority of votes cast by holders of
     the Company's common stock;
 
  .  obtaining all required consents and approvals;
 
                                       6
<PAGE>
 
 
  .  the Company receiving the debt financing contemplated by the financing
     commitment letter that has been delivered to the Company's Board of
     Directors or from other financing sources that are reasonably
     satisfactory to Bain Capital and Bear Stearns;
 
  .  the representations and warranties of the parties being true and correct
     in all material respects as of the Effective Time of the Merger except
     for certain changes that are specifically permitted; and
 
  .  the absence of any pending legal action by any governmental entity, or
     by any person other than a governmental entity which has a reasonable
     likelihood of success, seeking to restrain or prohibit the completion of
     the Merger.
   
   Even if the shareholders approve and adopt the Merger Agreement, there can
be no assurance that the Merger will be consummated. If the Company waives a
material condition to the Merger, it will then consider resoliciting
shareholder approval of the Merger. The decision to resolicit shareholders
approval will depend upon whether a shareholder could reasonably be expected to
take into account the waiver of the condition in deciding how to vote on the
Merger. See "The Merger Agreement--Conditions to the Merger."     
 
   No Solicitation. The Merger Agreement provides that neither the Company nor
any of its representatives will directly or indirectly
 
  .  initiate, solicit, or encourage or take any other action to facilitate
     any inquiry or proposal that constitutes, or could reasonably be
     expected to lead to, any Acquisition Proposal (as defined below) or
 
  .  enter into, maintain or continue negotiations with any person to obtain
     an Acquisition Proposal or agree to or endorse any Acquisition Proposal.
 
   Neither of these restrictions apply to persons to whom the Company provided,
within three months of the date of the Merger Agreement, non-public written
information in order to facilitate an Acquisition Proposal. The Company has
agreed to notify Merger Corp. of the relevant details relating to any
Acquisition Proposal inquiries and proposals that it receives and to provide
Merger Corp. with a reasonable opportunity to increase the Merger Consideration
in response to such Acquisition Proposal.
 
   The Board of Directors of the Company, however, is not prohibited from
responding to any unsolicited written, bona fide Acquisition Proposal if
 
  .  the Board of Directors, after consultation with PMG, determines in good
     faith that such Acquisition Proposal is more favorable to the Company
     and its shareholders from a financial point of view than the Merger
     (including any adjustment proposed by Merger Corp. in response to such
     Acquisition Proposal) and
 
  .  the Board of Directors, after consultation with its independent legal
     counsel, determines in good faith that such action is necessary for the
     Board of Directors to comply with its fiduciary duties to shareholders
     under applicable law (an Acquisition Proposal satisfying such criteria
     is called a "Higher Offer").
 
   Prior to accepting any Higher Offer, the Company must notify Merger Corp.
that it is taking such action and receive from such person or entity an
executed confidentiality agreement in reasonably customary form.
 
   The Merger Agreement defines the term "Acquisition Proposal" as any proposal
that constitutes 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. See "The Merger
Agreement--No Solicitation."
 
                                       7
<PAGE>
 
 
   Termination. The Merger Agreement may be terminated and the Merger
abandoned, at any time prior to the Effective Time, whether before or after
approval by the Company's shareholders, by:
 
  .  the mutual written consent of Merger Corp. and the Company;
 
  .  either Merger Corp. or the Company if the Merger has not been
     consummated by June 30, 1999, unless the terminating party has
     materially breached the Merger Agreement;
 
  .  either Merger Corp. or the Company if the consummation of the Merger
     would violate any nonappealable final order of court or other competent
     authority;
 
  .  Merger Corp. if the Company's Board of Directors (a) fails to recommend
     to the shareholders of the Company that they approve the Merger
     Agreement and the Merger, (b) withdraws or modifies its approval or
     recommendation of the Merger Agreement or Merger, (c) approves or
     recommends an Acquisition Proposal, (d) resolves to effect any of the
     foregoing or (e) otherwise takes steps to materially impede approval of
     the Merger Agreement and Merger by the shareholders;
 
  .  the Company or Merger Corp. if the shareholders of the Company have not
     duly approved the Merger and the Merger Agreement; or
 
  .  the Company if any person has made a bona fide proposal relating to an
     Acquisition Proposal or has commenced a tender or exchange offer for the
     common stock, and the Board of Directors or the Special Committee to the
     Board of Directors determines in good faith after consultation with its
     financial advisors, that such transaction constitutes a Higher Offer and
     after consultation with counsel, that failure to approve such proposal
     and terminate this Agreement could reasonably be expected to result in a
     breach of the Board's fiduciary duties to the Company's shareholders
     (assuming for such purpose that fiduciary duties are owed only to
     shareholders). See "The Merger Agreement--Termination of Merger
     Agreement."
 
   Termination Fee and Expenses. If the Merger Agreement is terminated for any
reason other than the following, then the Company will reimburse Merger Corp.
for its out-of-pocket expenses and fees up to $3.0 million:
 
  .  the failure of the Company or Merger Corp. to satisfy certain conditions
     of the Merger Agreement,
 
  .  primarily as a result of material adverse changes in the economy or
     industry or
 
  .  solely on the account of the failure of Merger Corp. to obtain financing
     for the Merger.
 
   If the Merger Agreement is terminated:
 
  .  by the Company or Merger Corp. because the shareholders of the Company
     fail to approve the Merger Agreement;
 
  .  by the Company if an Acquisition Proposal constitutes a Higher Offer and
     failure of the Company to approve the Acquisition Proposal and terminate
     the Merger Agreement could reasonably be expected to result in a breach
     of the Board's fiduciary duties to the Company's shareholders;
 
  .  by Merger Corp. because the Merger was not consummated on or before June
     30, 1999 and the Company materially breached the Merger Agreement; or
 
  .  by Merger Corp. because the Board of Directors failed to recommend or
     modified its recommendation that the shareholders approve the Merger
     Agreement; and
 
within 12 months after the date of such termination the Company enters into a
Business Combination, the Company will pay to Merger Corp. the sum of $6.0
million within three days following the consummation of such Business
Combination. See "The Merger Agreement--Fees and Expenses."
 
                                       8
<PAGE>
 
 
   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 Merger Corp. 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 stock of the
Company whether by tender or exchange offer or otherwise.

Certain Projections of Future Operating Results
 
  In connection with the review of the Company by the Equity Investors and in
the course of the negotiations between the Company and the Equity Investors as
described in "Special Factors--Background of the Merger," the Company provided
the Equity Investors with certain non-public business and financial
information. The non-public information provided by the Company included
certain projections of the Company's future operating performance. The
Company's projections (the "Company Projections") do not give effect to the
Merger or the financing of the Merger.
   
  The Company does not as a matter of course publicly disclose projections as
to future revenues or earnings. The Company Projections were not prepared with
a view to public disclosure and are included in the Proxy Statement only
because such information was made available to the Equity Investors in
connection with their due diligence investigation of the Company. Accordingly,
it is expected that there will be differences between actual and projected
results, and actual results may be materially different than those set forth
below. The Company Projections were not: (i) prepared with a view to compliance
with the published guidelines of the Commission regarding projections, (ii)
prepared in accordance with the guidelines established by the American
Institute of Certified Public Accountants for preparation and presentation of
financial projections or (iii) reviewed by an independent public accounting
firm. The material assumptions underlying the Company Projections are as
follows: (i) an increase in sales of approximately 18% per year, (ii) no
significant changes in gross margins, (iii) an increase in spending for
research and development and selling, general and administrative expenses
proportionate year-over-year to sales growth to support the expected increase
in sales and (iv) completion of the sale of certain assets to 3Com Corporation
and the sale/leaseback of the Company's Valley Forge headquarters. These
forward-looking statements reflect numerous assumptions made by the Company's
management. In addition, factors such as industry performance, general
business, economic, regulatory, market and financial conditions, all of which
are difficult to predict, may cause the Company Projections or the underlying
assumptions to be inaccurate. Accordingly, there can be no assurance that the
Company Projections will be realized, and actual results may be materially
greater or less than those contained in the Company Projections. See "Forward-
Looking Statements May Prove Inaccurate."     
 
  The inclusion of the Company Projections herein should not be regarded as an
indication that the Investors or the Company or their respective financial
advisors considered or consider the Company Projections to be a reliable
prediction of future events, and the Company Projections should not be relied
upon as such. None of the Company, the Investors or any of their financial
advisors intends to update or otherwise revise the Company Projections to
reflect circumstances existing after the date when made or to reflect the
occurrence of future events even in the event that any or all of the
assumptions underlying the Company Projections are shown to be in error.
 
  The Company provided to the Equity Investors the following Company
Projections:

                                SPECIAL FACTORS
 
Background of the Merger
 
   From time to time, the Company has engaged in discussions with potential
acquirors and with other parties regarding business combinations.
   
   On May 13, 1998, after informing the Board of Directors of the Company (the
"Board") of their planned meeting, Henry I. Boreen, Chairman of the Board and
interim Chief Executive Officer, and Hock E. Tan, Chief Financial Officer of
the Company, met with representatives of Bain Capital and Bear Stearns to
explore the possibility of forming an investor group to undertake a leveraged
buyout of the Company. At such meeting, Messrs. Boreen and Tan made a general
presentation regarding the Company. On May 13, 1998, the Company signed a
confidentiality agreement with Bear Stearns. On May 15, 1998, the Company
signed a confidentiality agreement with Bain Capital. Upon execution of the
confidentiality agreements, the Company provided Bain Capital and Bear Stearns
with legal and financial information related to the Company.     
   
   On May 14, 1998, the Company announced that it had received an unsolicited
oral inquiry from Cypress Semiconductor, Inc. about a possible acquisition or
strategic alliance. Based on such an inquiry, the Board authorized management
to hold preliminary discussions with and provide publicly available
information to representatives of Cypress Semiconductor. No offer was received
by the Company, and following such discussions, on May 28, 1998, Cypress
Semiconductor informed the Company that it had decided to suspend further
discussions. On May 28, 1998, the Company announced that discussions with such
company had been suspended.     
 
   On June 4, 1998, in response to unsubstantiated rumors, the Company
publicly denied that acquisition discussions were ongoing with Texas
Instruments.
   
   In June 1998, at a meeting of the Board, Mr. Boreen formally requested that
the Board consider a leveraged buyout of the Company by Mr. Boreen, certain
other members of senior management and the Equity Investors. Mr. Boreen
discussed with the Board the composition of the proposed investor group and
the general characteristics of the proposed transaction. The Board authorized
Mr. Boreen to continue his discussions with Bain Capital and Bear Stearns
regarding the proposed transaction and determined to discuss the matter
further if an acquisition proposal was submitted. Messrs. Boreen and Tan
retained independent legal counsel to represent them in connection with any
proposed transaction with the Company.     
 
   In June 1998, representatives of Bain Capital met with Mr. Boreen, Mr. Tan
and certain other members of the Management Group. At such meeting,
representatives of Bain Capital made a presentation to the management
attendees regarding Bain Capital, its investment history and strategy, and
current portfolio companies as well as a general description of the process
associated with a leveraged buyout. Following such meeting, representatives of
Bain Capital and Messrs. Boreen and Tan had several discussions regarding the
arrangements between the Management Group and the Equity Investors with
respect to a buyout of the Company. These discussions resulted in a general
understanding among such parties as to the approximate level of participation
of the Management Group in the buyout, the composition of the Surviving
Corporation's senior management team as well as the relative rights between
the Management Group and the Equity Investors with respect to their equity
ownership of the Surviving Corporation.
 
   In July 1998, the Board formed the Special Committee consisting of the
three then independent board members (Messrs. Gassner, Esber and Pickitt) to
consider any transaction proposed by the Investors. At that time, the Special
Committee formally engaged the Company's outside corporate counsel as counsel
to the Special Committee.
   
   During June and July 1998, management of the Company received inquiries
regarding possible business alliances from two parties. One of these parties
initially expressed a possible interest in a business combination, but it
later determined that it was only interested in securing intellectual property
rights from the Company in     
 
                                      12
<PAGE>
 
   
connection with product development efforts. Subsequently, discussions were
terminated by this party without reaching any agreement. A second party
expressed interest in exploring a strategic alliance with the Company to
develop frequency timing products for the personal computer market.
Discussions were held between representatives of this party and management of
the Company to explore the possibility of such an alliance and included the
possibility of a business combination. Discussions were later terminated by
this party without any offer being received by the Company. Both inquiries
were reviewed with the Board and the Board was kept informed of the progress
of discussions with both parties.     
 
   On August 12, 1998, the Special Committee held a meeting. At the meeting,
the Special Committee discussed the review of the Company being undertaken by
Bain Capital and Bear Stearns and determined, based upon the advice of legal
counsel, that the Special Committee should engage a financial advisor to be in
a position to analyze any transaction that might be proposed by the Investors.
   
   On August 20, 1998, the Special Committee held a meeting at which it
unanimously decided to engage PMG as its financial advisor to analyze any
acquisition proposal for the Company. The Special Committee also discussed a
draft non-binding expression of interest that was submitted to the Company by
Bain Capital on behalf of the Investors, with respect to a transaction that
would value each share of common stock of the Company in the range of $17.50
to $22.50. After extensive discussion, the Special Committee determined that
certain aspects of the expression of interest were unacceptable, including the
non-binding nature of the expression of interest and the payment of a break-up
fee equal to 1.5% of the aggregate value of any alternative transaction under
certain circumstances. Mr. Gassner, on behalf of the Special Committee, and
counsel to the Special Committee discussed with Bain Capital the Special
Committee's unwillingness to execute the expression of interest with Bain
Capital on behalf of the Investors.     
   
   On August 25, 1998, Bain Capital submitted to the Special Committee a
revised draft of the non-binding expression of interest which replaced the
break-up fee provision with an expense reimbursement provision up to a maximum
amount of $1.5 million.     
   
   On August 26, 1998, the Special Committee held a meeting to discuss the
revised draft of the expression of interest. After extensive discussion, the
Special Committee again determined that the expression of interest was
unacceptable. The Special Committee unanimously agreed to grant the Investors
until September 4, 1998 to consider making a proposal with respect to a
transaction with the Company. Counsel to the Special Committee relayed this
message to counsel to the Equity Investors following the Special Committee
meeting.     
   
   On October 1, 1998, a representative of Bain Capital discussed with Mr.
Gassner that the Investors would be willing to make, under certain conditions,
a proposal to acquire the Company that would value each outstanding share of
common stock of the Company at a price in the range of $16.00 to $17.50. At a
Special Committee meeting held on October 1, 1998, PMG discussed its analysis
of the proposal. PMG indicated that, if a formal proposal were made by the
Investors within that price range, PMG could not provide an opinion that the
proposal would be fair to the Company's unaffiliated shareholders from a
financial point of view.     
   
   On October 7, 1998, a group of senior managers of the Company, including
current executive officers Hock Tan and Lewis Eggebrecht, as well as
Christopher Bland, Ed Christiansen, Paul Lessard, Justine Lien, Barry Olsen
and Greg Richmond, sent a letter to the Board supporting the Investors'
proposal and recommending that the Board accept the proposal and submit it to
the Company's shareholders for their approval.     
   
   PMG subsequently updated its October 1 analysis, and on October 12 prepared
and circulated a detailed valuation analysis. The Special Committee held
additional meetings on October 12 and October 13, and the Board met on October
14, in each case to discuss the proposal.     
 
   On October 19, 1998, the Company issued a press release stating that a
financial group led by the Company's management was currently pursuing a
possible buyout of the Company and that such group was hopeful that
discussions would progress to the point that an offering in the range of up to
$17.50 per share could be submitted.

   On October 19, 1998, the Special Committee held a meeting at which PMG
delivered a presentation with respect to a written opinion that it was
delivering to the Special Committee in connection with the publicly announced
buyout proposal. PMG discussed with the Special Committee its determination
that any proposal with a value not greater than $17.50 per share would not be
fair to the unaffiliated shareholders of the Company from a financial point of
view. The Special Committee, after extensive discussion, determined not to
pursue the proposal by the Investors. Counsel to the Special Committee
conveyed the Special Committee's rejection of the proposal to counsel to Bain
Capital and Bear Stearns. The Special Committee decided that the Company's
outside counsel would continue to represent the Special Committee with respect
to the potential transaction with the Investors and that the Company should
seek separate outside counsel in connection with other general corporate
matters.     
 
   On November 3, 1998, Mr. Gassner was elected as the Company's Vice
President of Corporate Development and was appointed to succeed Mr. Boreen as
the Chairman of the Board effective January 1, 1999.
   
   On November 23, 1998, a representative of Bain Capital discussed with Mr.
Gassner Bain Capital's continued interest in making a proposal to acquire the
Company at a price in excess of $17.50. After several discussions between Bain
Capital and counsel to the Special Committee subsequent to November 23, 1998,
the Company allowed Bain Capital and Bear Stearns to conduct further legal and
accounting due diligence on the operations of the Company in order to
formulate an unconditional offer for the Company. Later in November 1998, Mr.
Gassner resigned as a member of the Special Committee as a result of his
assuming a more prominent role in the management of the Company. Since that
time, the Special Committee has consisted of Messrs. Esber and Pickitt.     
   
   On December 4, 1998, Bain Capital, on behalf of the Investors, proposed a
transaction with the Company that Bain Capital indicated would value each
share of the Company at $21.25. The consideration would be paid $19.75 in cash
and $1.50 in a preferred stock. The proposal included a break-up fee of $8.25
million, or approximately 3.1% of the total purchase price, plus reimbursement
of up to $3.0 million of expenses. Based upon the advice of its legal and
financial advisors, the Special Committee determined that the preferred stock
was not worth $1.50. In particular, the Special Committee considered the
advice of PMG that the preferred stock would have limited liquidity and that
its proposed dividend would result in a yield below that which investors would
seek in a highly leveraged technology company. Counsel to the Special
Committee contacted Bain Capital and its counsel and expressed the Special
Committee's view that the Investors should consider making a proposal to
acquire the Company at $21.25 per share in cash with a break-up fee not
exceeding 2% of the total purchase price. Bain Capital responded that it would
need to complete further due diligence to determine whether the Investors
wanted to proceed on such terms.     
   
   In mid-December 1998, PMG was contacted by a third party with respect to a
potential acquisition of the Company. The Board authorized the Special
Committee to engage in discussions with this potential acquiror. A
confidentiality agreement was entered into between the Company and the
potential acquiror on December 21, 1998 and the potential acquiror received
certain due diligence information regarding the Company. After several
discussions between PMG and the potential acquiror, the potential acquiror
determined that it was not interested in pursuing discussions further or in
making an acquisition proposal to the Company.     
   
   On December 15, 1998, the Special Committee met to discuss a proposal by
the Investors involving an all-cash purchase price of $21.25 per share,
subject to conditions requiring the Company to have a specified level of cash
at the Effective Time and the satisfactory completion of the Equity Investors'
due diligence review, as well as customary conditions. After extensive
discussions with its legal and financial advisors, the Special Committee
informed Bain Capital that it would not accept an offer with a due diligence
or minimum cash condition and directed its advisors to negotiate with Bain
Capital a transaction with the Investors that was fully financed and
unconditional other than customary conditions. Legal counsel for the parties
began drafting and negotiating definitive transaction documents, subject to
the approval of the Special Committee and the Board.

   On December 18, 1998, a group of senior managers of the Company, including
current executive officer Lewis Eggebrecht, as well as Christopher Bland, Paul
Lessard, Barry Olsen and Greg Richmond, sent a letter to the Board urging the
Board to accept the Investors' proposal in its then-current form and to submit
it to the Company's shareholders for their approval.     
   
   On January 4, 1999, the Board held a meeting at which the Board determined
to have PMG solicit indications of interest from a select group of potential
acquirors. Subsequent to that meeting, PMG contacted 12 potential strategic
acquirors, which were selected based upon (i) the markets they served, (ii)
their perceived ability to complete an acquisition of the Company, and (iii)
discussions between PMG and the Special Committee. Of the 12 potential
strategic acquirors selected, six expressed an interest in discussing the
possibility of an acquisition. PMG sent these six potential acquirors an
initial set of due diligence materials regarding the Company, with the
understanding that additional materials would be sent to any potential
acquiror that remained interested after reviewing the initial materials. In
subsequent discussions between PMG and these six potential acquirors, each of
the potential acquirors indicated that it had no interest in pursuing
discussions concerning a possible acquisition of the Company. The substance of
the discussions between PMG and these potential acquirors was not shared with
any of the Investors prior to the execution of the Merger Agreement.     
   
   On January 18, 1999, the Special Committee received a proposal from Bain
Capital, on behalf of the Investors, to engage in a merger of Merger Corp.
with the Company for a cash price of $21.25 per share. The proposal included
executed financing commitments, was subject only to customary conditions and
was accompanied by a letter stating that the proposal would be withdrawn if a
merger agreement were not entered into by the parties by 5:00 p.m. on January
19, 1999. The proposal included a break-up fee of $6 million, or approximately
2.3% of the total purchase price, plus reimbursement of up to $3.0 million of
expenses.     
 
   On January 19, 1999, the Special Committee met to consider the proposal. At
such meeting, PMG delivered its written opinion to the effect that the
consideration to be received by the Company's unaffiliated shareholders in the
Merger, as of such date, was fair to such shareholders from a financial point
of view. After a lengthy discussion regarding the terms of the Merger
Agreement, the Special Committee approved the terms of the Merger Agreement
and unanimously recommended to the Board that it approve the Merger Agreement.
On January 19, 1999, the Board, based on the unanimous recommendation of the
Special Committee, unanimously approved the terms of the Merger Agreement and
directed that it be submitted to the Company's shareholders for their
approval. On January 20, 1999, the parties executed the Merger Agreement.
   
   In the weeks following the execution of the Merger Agreement, the Company
and the Investors negotiated certain changes to the Merger Agreement,
consisting primarily of technical and corrective changes. On February 12,
1999, the Board unanimously approved Amendment No. 1 to the Merger Agreement,
and on February 16, 1999, the parties executed Amendment No. 1 to the Merger
Agreement.     
 
Recommendations of the Special Committee and the Board of Directors
 
   On January 19, 1999, the Special Committee unanimously determined that the
Merger Agreement and the transactions contemplated thereby, including the
Merger, are fair to and in the best interests of the Company and its
shareholders, and recommended that the Board and the shareholders of the
Company approve and adopt the Merger Agreement and the transactions
contemplated thereby.
   
   On January 19, 1999, the Board, based on the unanimous recommendation of
the Special Committee, unanimously determined that the Merger Agreement and
the transactions contemplated thereby, including the Merger, are fair to and
in the best interests of the shareholders, and recommended that the
shareholders of the Company approve and adopt the Merger Agreement and the
transactions contemplated thereby. Prior to participating in the
determinations and recommendations of the Board, Mr. Boreen identified his
participation in the Management Group and noted that as a result of such
participation he had a conflict of interest.

Reasons of the Company for the Merger     
   
   Special Committee. In reaching its determinations referred to under
"Recommendations of the Special Committee and the Board of Directors," the
Special Committee considered the factors listed below. The following
discussion of the factors considered by the Special Committee is not intended
to be exhaustive but summarizes the material factors considered:     
     
  (i) The Special Committee considered the historical market prices and
      recent trading activity of the Company's common stock and the fact that
      the Merger Consideration would enable the shareholders to realize a
      premium over the prices at which the Company's common stock has
      recently traded. In particular, the Special Committee was advised by
      PMG that the Merger Consideration represented a 14.9%, 21.4% and 39.3%
      premium over the closing market prices on January 19, 1999 (the date on
      which the Special Committee approved the Merger), January 12, 1999 (one
      week before the Special Committee approved the Merger), and December
      21, 1998 (approximately one month before the Special Committee approved
      the Merger), respectively.     
     
  (ii) The Special Committee considered the written opinion of PMG to the
       effect that, as of the date of such opinion, the Merger Consideration
       of $21.25 in cash per share of the common stock to be received by the
       Company's unaffiliated shareholders in the Merger was fair to such
       shareholders from a financial point of view, and also considered the
       analysis underlying such opinion. See "--Opinion of Financial
       Advisor." A copy of PMG's opinion, setting forth the assumptions made,
       matters considered and limitations on the review undertaken in
       connection with such opinion, is attached as Appendix B to this Proxy
       Statement and should be read carefully in its entirety.     
     
  (iii) The Special Committee considered information with respect to the
        historical results of operations, business and prospects of the
        Company, as well as the risks involved in achieving such prospects,
        the composition of the Company's current management team and the
        general economic and market conditions affecting the Company. In
        particular, the Special Committee noted that the semiconductor
        industry is highly volatile and very dependent upon retention of
        talented scientific, engineering and management personnel, as well as
        the fact that the Company had been conducting a search for a chief
        executive officer and could not be certain that an acceptable
        candidate could be hired in the near term.     
     
  (iv) The Special Committee considered the results of PMG's solicitation of
       interest from potential acquirors on behalf of the Special Committee
       and the prior discussions of the Company with other potential
       acquirors, and was of the view that the Merger represented the most
       attractive alternative available to maximize shareholder value. In
       particular, no offers or proposals were received from other potential
       acquirors as a result of PMG's activities. PMG further advised the
       Special Committee that it did not believe that the existence and
       magnitude of the break-up fee and expense reimbursement provision
       proposed in the Merger Agreement would deter any potential acquirors
       from making an acquisition proposal for the Company at a price
       exceeding the price available to shareholders in the Merger.     
 
  (v) The Special Committee also considered the likelihood of the
      consummation of the proposed transaction, the existence of signed
      financing commitments, the proposed structure of the transaction and
      anticipated closing date, and the conclusion that the Equity Investors
      were significant participants in the capital markets with established
      records of completing transactions.
 
  (vi) The Special Committee considered the risks inherent in trying to
       achieve the Company's long-term strategic plan in light of an
       immediate return of value to the Company's shareholders reflected in
       the Merger.
 
  (vii) The Special Committee also considered the fact that consummation of
        the Merger would preclude the shareholders from having the
        opportunity to participate in the future growth prospects of the
        Company. In addition, the Special Committee recognized that certain
        members of management will have the opportunity to benefit from any
        increases in the value of the Company following the Merger by reason
        of their continuing equity interest in the Surviving Corporation.
 
  (viii) The Special Committee also considered the terms and conditions of
         the Merger Agreement, including the ability of the Company to: (a)
         continue discussions with other potential purchasers who received
         non-public
 
                                      16
<PAGE>
 
     information from the Company within three months prior to the date of
     the Merger Agreement, (b) negotiate with any person or entity that makes
     an unsolicited written proposal to acquire the Company and (c) terminate
     the Merger Agreement under certain circumstances in the exercise of its
     fiduciary duties, including accepting a Higher Offer (as defined in the
     Merger Agreement).
   
   Mr. Boreen had a conflict of interest due to his participation in the
Management Group. As a result, Mr. Boreen did not serve on the Special
Committee. Mr. Gassner initially served as a member of the Special Committee as
a non-employee director, but resigned as a member of the Special Committee in
connection with assuming a more prominent role in the management of the
Company. Mr. Gassner is not a member of the Management Group.     
 
   The Special Committee did not consider either the net book value or the
liquidation value of the Company since each was materially lower than the
Merger Consideration.
   
   In view of the various factors considered by the Special Committee in
connection with its evaluation of the Merger and the Merger Consideration as
described above, the Special Committee did not find it necessary to quantify or
otherwise attempt to assign relative importance to the specific factors
considered in making its determination, nor did it evaluate whether such
factors were of equal importance. However, based upon these factors, the
evaluation of all the relevant information provided to them by the Company's
financial advisor and taking into account the existing trading ranges for the
Company's common stock, the Special Committee determined that the Merger,
including the Merger Consideration, was fair from a financial point of view, to
the Company's shareholders. In considering the factors described above,
individual members of the Special Committee may have given different weights to
different factors. The Special Committee did not consider any factors which led
the Special Committee to believe that the Merger was unfair to the
shareholders. As described further below, the Special Committee believes that
the Merger was considered in a manner that was procedurally fair to the
Company's shareholders.     
   
   Board of Directors. In reaching its determinations referred to under "--
Recommendations of the Special Committee and the Board of Directors," the Board
considered the following factors: (i) the determinations and recommendations of
the Special Committee; (ii) the analysis of the Special Committee referred to
above, which was expressly adopted by the Board; and (iii) the fact that the
Merger Consideration and the terms and conditions of the Merger Agreement were
the result of arm's-length negotiations between the Special Committee and the
Company, on the one hand, and the Equity Investors, on the other hand.     
   
   In view of the factors considered by the members of the Board in connection
with the evaluation of the Merger as described above, and the complexity of
such matters, the Board did not consider it practicable to, nor did it attempt
to, quantify, rank or otherwise assign relative weights to the specific factors
it considered in reaching its decision. The Board also relied on the experience
and expertise of the financial advisor to the Special Committee for
quantitative analysis of the financial terms of the Merger. See "--Opinion of
Financial Advisor." The Board did not find it necessary to quantify or
otherwise attempt to assign relative importance to the specific factors
considered in making its determination, nor did it evaluate whether such
factors were of equal importance. Rather, the Board conducted a discussion of,
among other things, the factors described above, including asking questions of
the Company's management and legal and financial advisors, and reached a
general consensus that the Merger was advisable and in the best interests of
the Company, its shareholders and the Company's other constituencies. In
considering the factors described above, individual members of the Board may
have given different weight to different factors. The Board did not consider
any factors which led the Board to believe that the Merger may be unfair to the
shareholders.     
 
   The Board determined that the Merger was procedurally fair because, among
other things: (i) the Special Committee consisted entirely of non-management,
non-affiliated independent directors appointed to represent the interests of
the shareholders; (ii) the Special Committee retained and was advised by
separate legal counsel; (iii) the Special Committee retained PMG as its
financial advisor to assist it in evaluating a potential transaction and
received advice from PMG; (iv) the Special Committee engaged in extensive
deliberations in evaluating the Merger and alternatives thereto; and (v) the
$21.25 per share price and the other terms and conditions of the
 
                                       17
<PAGE>
 
Merger Agreement resulted from active arm's-length bargaining between the
Special Committee, the Company and their representatives, on the one hand, and
the Equity Investors and their respective representatives, on the other hand.
The Board believed that such safeguards were sufficient to assure that the
Merger is fair to, and in the best interests of the Company's unaffiliated
shareholders.
   
Fairness of the Merger     
   
   Company and Management Affiliates. Based on the factors set forth above,
the Company believes that the consideration to be received by its unaffiliated
shareholders pursuant to the Merger is fair. The members of the Management
Group who are executive officers or directors of the Company (the "Management
Affiliates") also believe that the consideration to be received by the
Company's unaffiliated shareholders pursuant to the Merger is fair. The
Management Affiliates base their belief on the following facts: (i) the fact
that the Special Committee and the Board, based on the factors discussed under
"--Reasons of the Company for the Merger; Fairness of the Merger," concluded
that the Merger is fair to, and in the best interests of, the Company's
shareholders, (ii) notwithstanding the fact that PMG's opinion was addressed
to the Special Committee and the Board, and that the Management Affiliates are
not entitled to rely upon such opinion, the fact that the Special Committee
and the Board received an opinion from PMG that, as of the date of such
opinion and based on and subject to certain matters stated in such opinion,
the consideration to be paid in the Merger is fair to the Company's
unaffiliated shareholders from a financial point of view and (iii) the
negotiations between the Equity Investors, on the one hand, and the Company
and the Special Committee, on the other hand, of the terms of the Merger
Agreement were conducted on an arm's-length basis. The Management Affiliates
did not find it practicable to assign, nor did they assign, relative weights
to the individual factors considered in reaching their conclusion as to
fairness.     
   
   Equity Investors. The Equity Investors, as the parties proposing to gain
control of the Company, did not participate in the deliberations of the
Special Committee or the Board regarding the fairness of the Merger to the
Company's unaffiliated shareholders, nor did the Equity Investors receive any
advice from the Company's financial advisor as to the fairness of the Merger.
As a result, the Equity Investors are not in a position to specifically adopt
the conclusions of the Special Committee or the Board as to the fairness of
the Merger. However, based upon their own knowledge from publicly available
information regarding the Company and their understanding from discussions
with senior management of the Company regarding the factors considered by the
Special Committee and the Board referred to in "--Reasons of the Company for
the Merger," the Equity Investors also believe that the Merger is fair to the
Company's unaffiliated shareholders. In addition, the results of the due
diligence investigation conducted by the Equity Investors, which included
discussions with management regarding the Company's business (including
estimates discussed above under "--Certain Projections of Future Operating
Results" in connection with the Company Projections), visits to the Company's
facilities, document review and an analysis of comparable companies in the
industry, validated the belief of the Equity Investors that the Merger
Consideration is fair to the Company's unaffiliated shareholders. The factor
the Equity Investors consider of greatest importance in their analysis of
fairness is the fact that the Merger Consideration represents a significant
premium over the recent and historical market trading prices for the Company's
common stock. The Merger Consideration represents a 14.9% premium over the
closing market price on January 19, 1999, the date the Special Committee
approved the Merger, and a 60.5% premium over the average closing price during
the 180 days prior to such approval. Furthermore, pursuant to the terms of the
Merger Agreement, the Company is permitted to continue discussions with other
potential purchasers who received non-public information from the Company
within three months prior to the date of the Merger Agreement, to negotiate
with any person or entity that makes an unsolicited written proposal to
acquire the Company and to terminate the Merger Agreement under certain
circumstances in the exercise of the fiduciary duties of the Board.     
   
   The Equity Investors did not consider net book value, going concern value
or liquidation value to be material factors in determining the fairness of the
transaction to the unaffiliated shareholders, because they believe that these
factors do not have any significant impact on the market trading prices of the
Company's common stock. Notwithstanding the relative insignificance of these
factors, the Equity Investors believe that the Merger Consideration represents
a significant premium over the net book value of the Company's common stock
    
                                      18
<PAGE>
 
   
and, although the Company's liquidation value was never quantified, a very
significant premium over the Company's liquidation value, since they believe
the Company's principal assets, its real estate and inventory, would not
result in any significant gains in a liquidation. The Equity Investors did not
rely on any report, opinion or appraisal in determining the fairness of the
transaction to the Company's unaffiliated shareholders, but do not disagree
with any of the conclusions expressed by PMG in its opinion to the Special
Committee and the Board. Except as otherwise disclosed in this proxy
statement, the Equity Investors have not made any prior purchases of the
Company's common stock, and are not aware of any firm offers made in the last
18 months by an unaffiliated person to merge or consolidate with the Company,
to acquire all or any substantial part of the assets of the Company or to
acquire control of the Company. Based upon their involvement negotiating the
terms of the Merger Agreement, including the amount and type of Merger
Consideration to be received by the Company's shareholders, the Equity
Investors believe that procedures used by the Company and the Special
Committee in negotiating the Merger Agreement were fair to the Company's
unaffiliated shareholders. The foregoing analysis is expressly adopted by the
other respective affiliates of the Equity Investors that are included as
filing persons on the Schedule 13E-3 filed by the Equity Investors with the
SEC in connection with this transaction.     
 
Equity Investors' Reasons for the Merger
 
   The purpose of the Equity Investors for engaging in the Merger is to gain
control of the Company through a recapitalization. The Equity Investors
believe that the Company's future business prospects can be improved through
their active participation in the strategic direction and operations of the
Company. In addition, the Equity Investors believe that the high consolidated
debt-to-equity ratio of the Company after the Merger may allow the value of
the Company's equity to increase more rapidly on a percentage basis than would
the value of the equity in an otherwise identical corporation with a larger
equity base and relatively less debt. This assessment is based upon publicly
available information regarding the Company, the Equity Investors' due
diligence investigation of the Company and the Equity Investors' experience in
investing in technology companies. While the Equity Investors' believe that
there will be significant opportunities associated with their investment in
the Company, there are also substantial risks that such opportunities may not
be fully realized.
 
   The recapitalization of the Company has been structured as a merger in
order to permit the redemption of all of the Company's common stock (other
than the Converted Shares) and to preserve the Company's corporate identity
and existing contractual arrangements with third parties. The Equity Investors
did not consider other alternatives with respect to the structure of the
transaction.
 
Opinion of Financial Advisor
 
   The Special Committee, on behalf of itself and the Board, retained PMG to
render an opinion as to whether the compensation to be paid to the holders of
the Company's common stock, other than members of the Management Group, in the
Merger is fair, from a financial point of view, to such holders.
   
   ON JANUARY 19, 1999 PMG DELIVERED TO THE SPECIAL COMMITTEE AND BOARD ITS
WRITTEN OPINION TO THE EFFECT THAT, AS OF SUCH DATE, AND BASED UPON AND
SUBJECT TO THE VARIOUS ASSUMPTIONS AND CONSIDERATIONS SET FORTH IN SUCH
OPINION, THE MERGER CONSIDERATION OFFERED TO THE HOLDERS OF COMMON STOCK OF
THE COMPANY (OTHER THAN MEMBERS OF THE MANAGEMENT GROUP) WAS FAIR, FROM A
FINANCIAL POINT OF VIEW, TO SUCH HOLDERS. THE FULL TEXT OF THE OPINION OF PMG,
WHICH SETS FORTH THE ASSUMPTIONS MADE, MATTERS CONSIDERED AND SCOPE AND
LIMITATIONS OF THE REVIEW UNDERTAKEN AND PROCEDURES FOLLOWED BY PMG IN
RENDERING ITS OPINION, IS ATTACHED TO THIS PROXY STATEMENT AS APPENDIX B (WITH
PMG'S CONSENT) AND IS INCORPORATED HEREIN BY REFERENCE. THE FOLLOWING
DESCRIPTION OF THE OPINION OF PMG IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO
THE FULL TEXT OF THE OPINION. SHAREHOLDERS OF THE COMPANY ARE URGED TO READ
CAREFULLY THE OPINION OF PMG IN ITS ENTIRETY.     
 
                                      19
<PAGE>
 
   
   PMG's opinion is for the information of the Special Committee and the Board
only in addressing, as of January 19, 1999, the fairness, from a financial
point of view, to the Company's unaffiliated shareholders of the Merger
Consideration offered to such holders. Such opinion does not address any other
aspect of the Merger and does not constitute a recommendation to any
shareholder as to how such shareholder should vote with regards to the Merger.
PMG was not requested to opine as to, and its opinion does not in any manner
address, the underlying business decision to proceed with or effect the Merger
or the relative merits of the Merger as compared with any alternative business
strategies of the Company. PMG's position is that because, in accordance with
the terms of its engagement by the Company, it has no obligation to render an
opinion to anyone other than the Special Committee and the Board, it rendered
its opinion to assist the Special Committee and the Board in exercising their
business judgment, and it addressed the opinion solely to the Special
Committee and the Board, the Company's shareholders cannot rely on the opinion
to support any claims against PMG arising under applicable state law. The
issue of whether shareholders of the Company can rely on PMG's opinion turns
on matters of state law that can only be resolved by a court of competent
jurisdiction. Resolution of this question will have no effect on the rights
and responsibilities of the Special Committee or the Board under applicable
state law or the rights and responsibilities of PMG, the Special Committee or
the Board under the federal securities laws.     
   
   In conducting its analysis and arriving at PMG's opinion, PMG reviewed a
draft of the Agreement and Plan of Merger dated January 19, 1999.
Additionally, PMG held discussions with certain senior officers of the Company
concerning its business, operations and prospects. PMG also reviewed and
analyzed all publicly available business and financial information relating to
the Company that it believed to be relevant to its inquiry, as well as certain
financial forecasts and other data for the Company that are set forth
elsewhere in this Proxy Statement or that were otherwise discussed with PMG by
the management of the Company. PMG also reviewed, among other things, current
and historical market prices and trading volumes of the common stock. Based
upon the projected financial performance as adjusted for the sale of assets to
3Com Corporation, PMG made certain estimates as to the future cash flows and
terminal values, and, after applying a range of appropriate discount rates,
the present value of such cash flows and terminal value. Such analysis is
defined as a "Discounted Cash Flow Analysis." PMG also analyzed certain
financial, stock market and other publicly available information relating to
the businesses of other companies whose operations we considered relevant in
evaluating those of the Company. Furthermore, PMG examined the terms of
certain business combinations which it believed to be relevant and compared
the terms to the Merger.     
 
   The following are the material financial and other factors considered by
PMG in arriving at its opinion: (i) the current and historical trading markets
for the Company's common stock, including prices, trading volume, absolute
volatility and relative volatility compared to certain stock market indices;
(ii) the historical financial performance and the business prospects for the
Company; (iii) the current and historical trading markets, including prices
and valuation ratios, for the equity securities of certain companies that PMG
believes to be comparable to the Company; and (iv) the terms of certain other
business combinations that PMG believes to be relevant. PMG also took into
account its assessment of general economic, market and financial conditions,
certain industry trends and related matters and its experience in similar
transactions, as well as its experience in securities valuation in general.
PMG's opinion necessarily is based upon the foregoing and other conditions as
they existed and could be evaluated on the date of the opinion and on the
information made available to it as of such date.
 
   No limitations were imposed by the Board upon PMG with respect to the
investigations made or procedures followed by PMG in its review and analysis.
In rendering its opinion, PMG has assumed and relied, without independent
verification, upon the accuracy and completeness of all financial and other
information and data publicly available or furnished to or otherwise reviewed
by or discussed with us and have further relied upon the assurances of the
management of the Company that they are not aware of any facts that would make
such information inaccurate or misleading. With respect to financial forecasts
and other information and data provided to or otherwise reviewed by or
discussed with PMG, it was advised by the management of the Company that such
forecasts and other information and data were reasonably prepared on bases
reflecting the best currently
 
                                      20
<PAGE>
 
available estimates and judgments of the management of the Company as to its
future financial performance. PMG did not make and was not provided with an
independent evaluation or appraisal of the assets, liabilities (contingent or
otherwise) or reserves of the Company nor did it make any physical inspection
of the properties or assets of the Company. PMG's opinion is necessarily based
upon information available to it, and financial, stock market and other
conditions and circumstances existing and disclosed to it, as of the date
thereof.
 
   PMG made qualitative judgments as to the significance and relevance of each
analysis and factor considered as a whole. PMG believes that its analyses must
be considered in the aggregate, and that selecting portions of its analyses or
the factors considered by it, without considering all factors and analyses,
could create a misleading or incomplete view of the process underlying its
opinion. The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analyses or summary description.
 
   In arriving at its fairness opinion, PMG did not attribute any particular
weight to any analysis or factor considered by it. No company or transaction
used in the above analyses as a comparison is directly comparable to the
Company or the contemplated transaction. In performing its analyses, PMG made
numerous assumptions with respect to forecasts of future results, industry
performance, market and financial considerations and other matters. Analyses
based upon such forecasts are not necessarily indicative of actual future
results, which may be significantly more or less favorable than those
suggested by such analyses. In addition, analyses relating to the value of
businesses or securities do not purport to be appraisals or to reflect the
prices at which businesses or securities actually may be sold. PMG's
presentation to the Board was only one of many factors taken into
consideration by the Board in making its determination to approve the Merger
and related transactions.
   
   The following is a summary of the material financial analyses utilized by
PMG in rendering its opinion.     
 
   Comparable Company Analysis. PMG compared selected financial data and
financial ratios of the Company to the corresponding data and ratios of
certain publicly traded manufacturers of semiconductors and integrated
circuits. The reference companies were selected based on general business,
operating and financial characteristics, including primary lines of business,
market capitalization, total revenues and various measures of profitability.
Specifically, the companies included in PMG's review were: Actel Corporation,
Dallas Semiconductor Corporation, Exar Corporation, Lattice Semiconductor
Corporation, NeoMagic Corporation and Pericom Semiconductor Corporation (the
"Comparable Companies").
   
   PMG also compared multiples for the Merger implied by the Merger
Consideration and certain historical and projected financial data of the
Company, as adjusted for the sale of assets to 3Com Corporation, to the
corresponding implied trading multiples of the Comparable Companies. While
none of the Comparable Companies was identical to the Company, PMG considered
that certain valuation parameters established by the public markets and
imputed from stock prices with respect to the Comparable Companies, when
viewed in conjunction with certain qualitative factors, were relevant when
considering the valuation of the Company, since the Comparable Companies
exhibited certain business characteristics similar to those exhibited by the
Company. In this portion of its analysis, PMG compared (i) enterprise value
(value of equity plus net debt) as a multiple of latest twelve months ("LTM")
revenue, (ii) enterprise value as a multiple of LTM earnings before interest
and taxes ("EBIT"), (iii) equity value as a multiple of LTM earnings, (iv)
equity value as a multiple of projected twelve months ending July 3, 1999
earnings (projected earnings figures for the Comparable Companies were based
on quarterly information for calendar 1998 and 1999 from Zacks Investment
Research and independent research analysts; projected earnings figures for the
Company were based on the Company's fiscal 1999 internal plan, as adjusted for
the sale of assets to 3Com Corporation), and (v) equity value as a multiple of
book value.     
   
   The implied multiples for the Merger based on the Merger Consideration and
the Company's financial data, as adjusted for the sale of assets to 3Com
Corporation, compare as follows with the multiples for the Comparable
Companies using closing share prices as of January 19, 1999: (i) enterprise
value to LTM revenue ranged from 0.8x to 4.1x (with a median of 2.0x) for the
Comparable Companies versus 1.7x for the Merger, (ii) enterprise     
 
                                      21
<PAGE>
 
   
value to LTM EBIT ranged from 9.8x to 16.6x (with a median of 12.2x) for the
Comparable Companies versus 9.0x for the Merger, (iii) equity value to LTM
earnings ranged from 16.5x to 28.0x (with a median of 22.3x) for the
Comparable Companies versus 15.5x for the Merger, (iv) equity value to
projected 1999 earnings ranged from 14.2x to 33.6x (with a median of 22.5x)
for the Comparable Companies versus 13.0x for the Merger and (v) equity value
to book value ranged from 1.1x to 5.3x (with a median of 2.7x) for the
Comparable Companies versus 2.5x for the Merger.     
   
   However, because of the inherent differences between the businesses,
operations and prospects of the Company and the businesses, operations and
prospects of the Comparable Companies, PMG believed that it was inappropriate
to, and therefore did not, rely solely on the quantitative results of the
analysis (including the implied multiples for the Merger described above) and
accordingly also made qualitative judgements concerning differences between
the financial and operating characteristics and prospects of the Company and
the Comparable Companies which would affect the public trading values of the
Company and the Comparable Companies. The qualitative judgments included (i)
the lack of a chief executive officer and president since April 1998, as well
as a high level of turnover in the position; (ii) the dependence of the
Company on the frequency timing generator market, as well as the limited
potential upside in the market for personal computer frequency timing
generators, the Company's core product, due to the Company's dominant market
share in the area and forecasts of personal computer industry growth; (iii)
the risks and likelihood associated with the Company's products being replaced
or made obsolete and (iv) the relative attractiveness of the Company as a
strategic acquisition candidate due to the markets in which it competes. In
particular, PMG studied the Company's results and current forecasts for the
future quarters and compared those numbers with research analyst estimates of
the Company's current and future financial performance. In addition, PMG took
into consideration the fact that the Company competes in a highly competitive
market.     
   
   Discounted Cash Flow Analysis. PMG developed, with input from the Company,
a Discounted Cash Flow Analysis of the Company based on projected financial
statements, as adjusted for the sale of assets to 3Com Corporation, through
the fiscal year ending 2003. These projections assumed, among other things,
(i) that the year-over-year increases in revenue for the fiscal years ending
1999 through 2003 would range from 12.0% to 23.5%, and (ii) that the operating
margin (operating income as a percentage of revenues) for the fiscal years
ending 1999 through 2003 would range from 16.0% to 18.4%. Specifically, these
projections assumed (i) that revenues for the fiscal years ending 1999 through
2003 would be $151.8 million, $170.0 million, $210.0 million, $252.0 million
and $293.0 million, respectively; (ii) that gross profit for the fiscal years
ending 1999 through 2003 would be $70.8 million, $78.2 million, $96.6 million,
$115.9 million and $134.8 million, respectively (iii) that operating profit
for the fiscal years ending 1999 through 2003 would be $27.9 million, $28.9
million, $34.3 million, $40.3 million and $46.8 million, respectively; (iv)
that net income for the fiscal years ending 1999 through 2003 would be $20.2
million, $22.2 million, $27.3 million, $31.6 million and $37.5 million,
respectively; and (v) that net earnings per share for the fiscal years ending
1999 through 2003 would be $1.64, $1.67, $2.02, $2.30 and $2.68, respectively.
    
   The projected cash flows consisted of the after-tax free cash flow for the
six months ending July 3, 1999 and the fiscal years ending 2000 through 2003
plus a terminal value at fiscal year end 2003. In estimating the appropriate
terminal value at fiscal year end 2003, PMG applied a multiple of 7.0x to
estimated EBIT in fiscal year 2003 with reference to the corresponding
multiples of the Comparable Companies. Acquisition and trading multiples from
time to time fluctuate considerably, and no assurance can be made that future
trading multiples will be comparable to historical levels.
 
   The present value of the stream of projected cash flows was obtained by
discounting the cash flows to December 31, 1998 using a range of weighted
average costs of capital ("WACC") of 17.39% to 19.39% with a mid-point of
18.39% estimated based on the historic beta of the Company's common stock and
with consideration to the small market capitalization of the Company. The
foregoing analysis resulted in a range of estimated present values of $18.86
to $19.85 per share of the common stock, with a mid-point of $19.35.

   Selected Merger and Acquisition Transactions Analysis. Using publicly
available information, PMG evaluated acquisitions of certain semiconductor
companies (the "Acquisitions Companies"). Each of the Acquisition Companies is
distinguishable from the Company in certain respects. The acquisitions used in
PMG's analysis were (target/acquirer): Integrated Process Equipment/Integrated
Device Tech Inc., Quality Semiconductor/Integrated Device Tech Inc., Benchmarq
Microelectronics Inc./Unitrode Corp., BKC Semiconductor Inc./Microsemi Corp.,
Cyrix Corp./National Semiconductor Corp., Chips & Technologies Inc./Intel
Corp., Panatech Research & Development/Harbour Group Ltd., Brooktree
Corp./Rockwell International Corp., VLSI Technology/Investor Group, and
Catalyst Semiconductor Inc./United Microelectronic Corp.     
 
   PMG calculated a range of multiples based on the ratio of (i) the implied
transaction value (calculated as equity value of the transaction plus assumed
debt) to LTM net sales and EBIT reported prior to the announcement of the
selected transaction, (ii) the implied equity value to LTM net income and
earnings reported prior to the announcement of the selected transaction, and
the stated book value prior to the announcement of the selected transaction,
and (iii) the implied equity value as a premium to the target's historical
stock price for one day, one week and one month prior to the announcement of
the selected transaction.
   
   The implied multiples for the Merger based on the Merger Consideration and
the Company's financial data compare as follows with the multiples for the
Acquisition Companies: (i) implied transaction value to LTM revenue ranged
from 0.6x to 3.2x (with a median of 1.9x) for the Acquisition Companies versus
1.7x for the Merger, (ii) implied transaction value to EBIT ranged from 10.5x
to 17.6x (with a median of 12.5x) for the Acquisition Companies versus 9.0x
for the Merger, (iii) implied equity value to net income ranged from 14.4x to
37.6x (with a median of 19.1x) for the Acquisition Companies versus 15.0x for
the Merger, (iv) implied equity value to earnings ranged from 13.7x to 39.2x
(with a median of 18.3x) for the Acquisition Companies versus 15.5x for the
Merger and (v) implied equity value to stated book value ranged from 1.1x to
4.3x (with a median of 3.0x) for the Acquisition Companies versus 2.5x for the
Merger. The median implied equity value as a premium to the target's one day,
one week and one month historical stock prices was 30.3% (with a range of
- -2.9% to 66.7%), 32.1% (with a range of 0.0% to 146.2%) and 44.6% (with a
range of 11.6% to 131.3%), respectively, for the Acquisition Companies versus
19.7%, 18.1%, and 33.3%, respectively for the Merger. Assuming Merger
Consideration of $21.25 per share, the Merger multiples were within the range
of multiples of the Acquisition Companies. In evaluating the premium of the
Merger Consideration to the historical stock prices of the Company, PMG
considered the publicity associated with the Company since the Company's
October 19, 1998 press release describing a possible management led buyout,
the speculation of a possible revised offer by management following a
rejection of management's proposal, and the possible effect of such publicity
and speculation on the Company's stock price in the period between October 19,
1998 and the date the Merger was announced.     
 
   Stock Trading History. PMG reviewed, for the period from the Company's
initial public offering through January 19, 1999, the stock price performance
of the common stock, the historical trading volume of common stock, the
absolute volatility and the volatility of the common stock compared to the S&P
500 Index and the Philadelphia Semiconductor Index. PMG compared the absolute
and relative volatility of the Company's common stock to the volatility of the
Comparable Companies. Such comparison revealed that the Company had a 97.5
relative volatility compared to a median relative volatility of 71.1 for the
Comparable Companies for the six-month period prior to January 19, 1999. In
general, a higher relative volatility, particularly for companies whose
trading volumes for their common stock are relatively low, will result in a
higher desired rates of return, or discount rate, for investors.
 
   Pursuant to a letter agreement dated August 17, 1998 (including amendments
thereto) between the Company and PMG, the Company paid PMG fees totalling
$325,000 in consideration of financial advisory services rendered to the
Special Committee, including the rendering of a written opinion on October 19,
1998. Pursuant to an amended and restated letter agreement dated as of August
17, 1998 and entered into on January 19, 1999, PMG received a fee of $125,000
in connection with PMG's delivery to the Special Committee and the Board of
 
                                      23
<PAGE>
 
its fairness opinion dated January 19, 1999 relating to the Merger. Pursuant
to the amended and restated letter agreement, PMG will receive an additional
fee of $125,000 upon consummation of the Merger. In the event of a business
combination transaction with a party other than Bain Capital or its
affiliates, PMG would receive an additional fee of 0.5% of the cash plus the
fair value of any equity and debt securities issued to the Company's
shareholders in the transaction. In addition, the Company has agreed to
reimburse PMG for its reasonable costs and expenses (including legal fees and
disbursements) incurred in connection with rendering financial advisory
services. The Company has agreed to indemnify PMG for certain costs, expenses,
losses, claims, damages and liabilities, including those under federal
securities laws, related to or arising out of its rendering of services under
its engagement as financial advisor.
   
   In performing its financial analyses, PMG made numerous assumptions with
respect to industry performance, general business and economic conditions, and
other matters, many of which are beyond the control of the Company. The
preparation of an opinion involves various determinations as to the most
appropriate and relevant methods of financial analysis and the application of
these methods to the particular circumstances based upon experience and
judgment. Accordingly, notwithstanding the separate factors summarized above,
PMG believes that its analyses must be considered as a whole and that
selecting portions of its analyses and factors considered by it, without
considering all analyses and factors, could create an incomplete view of the
evaluation process underlying PMG's opinion.     
 
Conflicts of Interest
   
   In considering the recommendations of the Special Committee and the
Company's Board of Directors, the Company's shareholders should be aware that
certain members of the Management Group and of the Company's Board of
Directors have interests in the Merger beyond the interests of the
shareholders generally which create conflicts of interest.     
   
   Equity Investment. It is important to the Equity Investors that the
Company's key personnel continue to manage and operate the Company following
the Merger and that they have meaningful incentives, including equity
ownership interests, to make the Company financially successful. Accordingly,
certain members of the Management Group will: (i) receive shares of common
stock of the of the Surviving Corporation in exchange for certain of their
shares of common stock of the Company under the terms of the Merger Agreement,
(ii) be afforded the opportunity to convert certain of their existing stock
options into options to purchase shares of common stock of the Surviving
Corporation in such a manner as to preserve the equity value of such options
(i.e., the difference between $21.25 and the exercise prices of such options)
and (iii) be granted additional options, with an exercise price equal to or
greater than fair market value at the Effective Time, to purchase shares of
the Surviving Corporation's common stock (the "New Options"). In addition, the
Company expects to enter into deferred compensation arrangements with certain
members of the Management Group.     
   
   The Management Group consists of 13 members of management, including
Messrs. Boreen, Tan and Eggebrecht as well as the senior level managers of
virtually every functional and business unit in the Company. Besides Messrs.
Boreen, Tan and Eggebrecht, the Company's other executive officers and
directors are not members of the Management Group. As of the Record Date, the
Management Group owned an aggregate of approximately [766,300] shares of the
Company's common stock and held options to purchase an aggregate of [810,237]
shares of common stock.     
 
                                      24
<PAGE>
 
   
   It is currently expected that the Management Group will invest an aggregate
of approximately $10.0 million in the Surviving Corporation. The amount to be
invested by the Management Group represents primarily the fair value of the
Converted Shares (valued at $21.25 per share) and the Converted Options
(valued at the equity value of such options). Certain members of the
Management Group will obtain a portion of the funds to be used to make their
respective equity investments through borrowings from the Surviving
Corporation. The approximate amount to be invested by each director or
executive officer of the Company who is a member of the Management Group is
set forth below:

   Following the Merger, it is expected that the Management Group will own, in
the aggregate, Converted Shares representing approximately 9.5% of the
Surviving Corporation's outstanding common stock on a fully-diluted basis,
Converted Options representing approximately 7.4% of the Surviving
Corporation's common stock on a fully-diluted basis and New Options
representing approximately 7.3% of the Surviving Corporation's common stock on
a fully-diluted basis.
   
   Certain Arrangements with the Equity Investors. The Equity Investors will
receive shares representing approximately 67.8% of the Surviving Corporation's
common stock outstanding immediately after the Merger on a fully-diluted basis
for an aggregate consideration of approximately $40 million. The Equity
Investors will receive a transaction fee from the Surviving Corporation upon
the consummation of the Merger in the amount of approximately $5.1 million. In
addition, each of the Equity Investors will enter into an advisory agreement
with the Surviving Corporation pursuant to which each will render certain
management and advisory services to the Surviving Corporation for which the
Equity Investors will receive from the Surviving Corporation an aggregate fee
of $1 million. Each advisory agreement will be in effect for an initial term
of ten years, subject to termination by the Equity Investors or the Company
upon written notice 90 days prior to the expiration of the initial term. The
Equity Investors will receive a fee of 1% of the aggregate value for any
acquisition, divestiture or financing by the Company. Each advisory agreement
will include customary indemnification provisions in favor of each of the
Equity Investors.     
 
   In connection with the Merger, the Equity Investors and certain members of
the Management Group of the Surviving Corporation will enter into a
shareholders agreement, registration rights agreement and subscription
agreement, which will provide for, among other things, restrictions on
transfer, "drag-along" and "tag-along" rights, registration rights, and put
rights. The terms of these agreements are not yet finalized.
   
   Employment and Consulting Agreements. In connection with the Merger, Mr.
Hock E. Tan is expected to enter into a three-year employment contract with
the Surviving Corporation. Under the terms of this agreement he will serve as
President and Chief Executive Officer of the Surviving Corporation with a base
salary of $250,000 per year. In addition to the base salary, Mr. Tan will be
eligible to earn an annual bonus of up to 100% of his base salary based upon
the Company attaining certain performance targets established annually by the
Board. During his term of employment, Bain Capital has agreed to nominate Mr.
Tan to serve as a member of the Board. If Mr. Tan is terminated without cause,
then he will be entitled to receive, during the remaining term of the
employment agreement or the twelve months following his termination, whichever
is longer, 125% of his base salary plus the target bonus he would have
otherwise been entitled to receive (in each case prorated for the number of
days of employment prior to termination). In the event of termination for
cause, Mr. Tan will be entitled to his base salary through the date of
termination. Mr. Tan's employment agreement will contain provisions
prohibiting him from disclosing confidential information and competing with
the Company. All     
 
                                      25
<PAGE>
 
   
inventions and intellectual property rights conceived, developed, made or
reduced to practice by Mr. Tan, other than those he develops entirely on his
own time without using the Company's property, will be assigned to the
Company.     
   
   Mr. Henry I. Boreen is expected to enter into a three-year consulting
contract with the Surviving Corporation. Under the terms of Mr. Boreen's
consulting agreement, he will be paid $350,000 per year in monthly
installments, and he will not be entitled to any fringe benefits or
perquisites from the Company. During the term of the consulting agreement, Mr.
Boreen will make himself reasonably available to render advice and services to
the Company as may be reasonably required by the Company and as are consistent
with the type of duties and services he has previously rendered to the
Company. In no event will Mr. Boreen be required to be available to the
Company for more than twelve days in any one-year period. The Company or Mr.
Boreen may terminate the consulting agreement upon thirty days prior written
notice. In the event the Company terminates Mr. Boreen for any reason, he
shall be entitled to receive the unpaid payments in a lump sum within thirty
days of his termination. Mr. Boreen's consulting agreement will contain
provisions prohibiting him from disclosing confidential information and
competing with the Company. If Mr. Boreen breaches the provisions prohibiting
him from competing with the Company, then he will no longer be entitled to
receive any further payments under the consulting agreement. All inventions
and intellectual property rights conceived, developed, made or reduced to
practice by Mr. Boreen, other than those that he develops entirely on his own
time without using the Company's property, will be assigned to the Company.
The terms of Mr. Tan's employment agreement and Mr. Boreen's consulting
agreement have not yet been finalized.     
   
   Treatment of Stock Options. Certain directors and executive officers of the
Company hold options to purchase the Company's common stock. Under the terms
of the Merger Agreement, each holder of outstanding options (other than the
Converted Options), whether or not such options are exercisable, will be
entitled to receive (subject to applicable withholding taxes) an amount in
cash equal to the product of (i) the difference between $21.25 and the
exercise price of such option and (ii) the number of shares of the Company's
common stock subject to such option. The directors and executive officers of
the Company who own options will receive this option consideration as a result
of the Merger for all of their options other than the Converted Options. As of
March  , 1999, there were options outstanding to purchase an aggregate of
[2,325,484] shares of the Company's common stock at a weighted average
exercise price of [$15.00] per share.     
 
   The following table sets forth information as to the options outstanding on
February 12, 1999, for which cash payment will be received upon consummation
of the Merger, and the proceeds expected to be received upon termination of
such options by the directors and executive officers of the Company:

   Director and Officer Indemnification and Insurance. The Company agreed in
the Merger Agreement to indemnify after the Effective Time the Company's and
any of its subsidiaries' current and former officers and directors for any
losses, claims, damages, costs and other liabilities or claims made against
such persons because they were a director or officer of the Company to the
fullest extent permitted by the PBCL. In addition, the Merger Agreement
provides that for six years after the Effective Time, the Company will
maintain its current directors' and officers' liability insurance for the
benefit of its directors and officers (or substitute policies of at least the
same coverage and containing terms not materially adverse to the indemnified
parties); provided, however, the Company is not required to pay an annual
premium in excess of 200% of the last annual premium paid by the Company prior
to the date of the Merger Agreement. With respect to the pending action filed
in
 
                                      26

connection with the announcement of the proposed Merger, Henry I. Boreen and
Hock E. Tan are, and any other director or executive officer who may be named
as a defendant in the future would be, entitled to the foregoing
indemnification. See "Recent Developments."     
 
   Stock Ownership. An affiliate of Bain Capital owns 74,600 shares of common
stock of the Company, which was purchased by such affiliate for investment
purposes at a weighted average price per share equal to $12.74. These shares
will be converted into the Merger Consideration upon completion of the Merger.
 
   Special Committee and Board Compensation. Compensation paid to the members
of the Special Committee and the Board for services rendered in their capacity
as members of the Special Committee or the Board for the period from June 1998
through June 19, 1999, including, among other things, their analysis and
evaluation of the acquisition proposals made by the Investors as well as their
negotiation of the terms of the Merger Agreement, amounted to $32,500 for Mr.
Gassner and Mr. Esber and $36,000 for Mr. Pickitt. Such amounts do not include
salary and benefits paid to Mr. Gassner as an officer of the Company since
November 3, 1998, or salary paid to Mr. Boreen as an executive officer of the
Company during 1998.
 
Recent Developments
   
   On January 15, 1999, the Company entered into a definitive agreement to
sell the intellectual property and engineering hardware and software related
to its data communications product line to 3Com for $16.0 million in cash.
This transaction was consummated on February 18, 1999. Under the agreement,
the Company retained certain licensing and technical support rights, and will
continue to sell and support its existing and prospective networking
transceiver product family to current and new customers.     
   
   On January 18, 1999, the Company entered into an agreement of sale with BET
Investments III, L.P. to sell the land and property of the Company's Valley
Forge headquarters. The purchase price for the property is $5.3 million. On
January 29, 1999, the Company signed a lease with BET Investments IV, L.P. to
lease back the Valley Forge building for a term of eight years, which will go
into effect upon closing of the sale of the property by the Company. The
Company leased back the entire building of approximately 61,000 square feet,
with monthly rent beginning at approximately $51,000 for the first year and
progressively increasing each year to approximately $63,000 in the eighth
year. The Company also has a renewal option of three more years subsequent to
the initial eight year term. Neither BET Investments III, L.P. nor BET
Investments IV, L.P. is affiliated with the Company or any of the Investors.
       
   On January 27, 1999, Harbor Finance Partners and John P. McCarthy Money
Purchase Plan, shareholders of the Company, filed a complaint on behalf of a
purported class of shareholders of the Company in the Court of Common Pleas of
Montgomery County, Pennsylvania against the Company and Henry I. Boreen in his
capacity as interim Chief Executive Officer of the Company alleging that the
Merger Consideration is inadequate and seeking to enjoin the Merger. In March
1999, the plaintiffs amended their complaint to add Hock E. Tan as a defendant
in his capacity as Senior Vice President, Chief Financial Officer, Chief
Operating Officer and Secretary of the Company. The Company believes that the
complaint is without merit and intends to vigorously defend the action.     
 
   The Company's Annual Meeting of Shareholders for fiscal 1998 was held on
February 1, 1999. At the meeting, the following nominees of the Company were
reelected to the Board: Henry I. Boreen, Edward M. Esber, Jr., Rudolf S.
Gassner and John L. Pickitt.

                              THE SPECIAL MEETING
 
General
 
   The Special Meeting of the shareholders of the Company will be held at the
offices of the Company, 2435 Boulevard of the Generals, Norristown,
Pennsylvania, on       , 1999 at 10:00 a.m., local time to (i) consider and
vote upon the approval and adoption of the Merger Agreement and (ii) transact
such other business as may properly come before the Special Meeting or any
adjournment thereof.
 
   The Company's Board of Directors has unanimously approved the Merger
Agreement and the transactions contemplated thereby and has determined that
such transactions are in the best interests of the Company and its
shareholders. The Company's Board of Directors unanimously recommends that the
Company's shareholders vote for approval and adoption of the Merger Agreement.
 
Record Date; Quorum
   
   Only shareholders of record of the Company at the close of business on the
Record Date will be entitled to notice of, and to vote at, the Special
Meeting. On the Record Date, there were [12,166,450] shares of the Company's
common stock outstanding. Except as noted below, each holder of shares of the
Company's common stock outstanding on the Record Date is entitled to one vote
for each such share so held, exercisable in person or by properly executed and
delivered proxy, at the Special Meeting. The presence of the holders of at
least a majority of the shares of the Company's common stock outstanding on
the Record Date and entitled to vote on the Merger Agreement, whether present
in person or by properly executed and delivered proxy, will constitute a
quorum for purposes of consideration of and action on the Merger Agreement.
       
   Brokers who hold shares in street name for customers that do not receive
voting instructions from customers do not have the authority under the rules
of the various stock exchanges to vote those shares with respect to the
approval and adoption of the Merger Agreement. Shares held by brokers that are
not voted on the Merger Agreement because the brokers have not received their
customers' voting instructions (referred to as "broker non-votes") are not
entitled to be voted at the Special Meeting and therefore will not be taken
into account in determining the presence of a quorum with respect to the vote
on the Merger Agreement, whereas shares with respect to which abstentions are
recorded are considered present for quorum purposes.     
       
Vote Required
   
   The affirmative vote of a majority of the votes cast at the Special Meeting
by all of the holders of record of the Company's common stock as of the Record
Date entitled to vote on the Merger Agreement is necessary to approve and
adopt the Merger Agreement. Where shareholders have appropriately specified
how their proxies are to be voted, they will be voted accordingly. Abstentions
and broker non-votes will not count for or against the Merger Agreement at the
Special Meeting.     
   
   In addition to the required vote described above, the Board considered
requiring an additional vote of a majority of the votes cast by all
shareholders unaffiliated with the Investors to approve and adopt the Merger
Agreement. However, because the Investors own an insubstantial amount of the
Company's common stock and applicable legal requirements did not mandate such
additional vote, the Board determined not to require any additional vote.     
 
   The Merger Agreement provides that certain shares held by members of
management will be converted into shares of the Surviving Corporation while
all other outstanding shares will be converted into Merger Consideration.
Under Section 1906 of the PBCL, such disparate treatment is permitted if
approved by a majority of votes cast by all shareholders entitled to vote on
the Merger Agreement. Approval by shareholders of the Merger Agreement will
also constitute approval of such treatment.
 
   As of the Record Date, directors and executive officers of the Company
owned an aggregate of [421,282] shares of common stock (approximately 3.0% of
the outstanding common stock). The directors and executive officers of the
Company have indicated that they intend to vote their shares of common stock
in favor of the adoption of the Merger Agreement. See "Beneficial Ownership of
Common Stock."

Proxies
 
   Shareholders are requested to complete, date and sign the accompanying form
of proxy and return it promptly in the enclosed postage-paid envelope.
 
   Any shareholder giving a proxy pursuant to this solicitation has the power
to revoke it at any time before it is voted at the Special Meeting. A later
dated proxy or written notice of revocation given prior to the vote at the
Special Meeting to the Secretary of the Company will serve to revoke such
proxy. Also, a shareholder who attends the Special Meeting in person may, if
he or she wishes, vote by ballot at the Special Meeting, thereby canceling any
proxy previously given. Mere presence at the Special Meeting will not serve to
revoke any proxy previously given.
 
Solicitation of Proxies
 
   In addition to the use of mails, proxies may be solicited by persons
regularly employed by the Company, by personal interview, telephone and
telegraph. Such persons will receive no additional compensation for such
services, but will be reimbursed for any out-of-pocket expenses incurred by
them in connection with such services. Arrangements may also be made with
brokerage houses and other custodians, nominees and fiduciaries for the
forwarding of solicitation materials to the beneficial owners of shares of the
Company's common stock held of record by such persons, and the Company may
reimburse such persons for reasonable out-of-pocket expenses incurred by them
in connection therewith.
 
   The Company will bear the costs of the Special Meeting and of soliciting
proxies therefor. Innisfree M&A Incorporated will assist in the solicitation
of proxies by the Company for a base fee of $     plus reasonable out-of-
pocket expenses.
 
Other Matters to be Considered
 
   The Company's Board of Directors is not aware of any other matter which
will be brought before the Special Meeting. If, however, other matters are
presented, proxies will be voted in accordance with the discretion of the
holders of such proxies.

                                  THE MERGER
 
Effective Time and Consequences of the Merger
 
   If approved by the requisite vote of the shareholders of the Company and if
all other conditions to the consummation of the Merger are satisfied or
waived, the Merger will become effective, unless the Merger Agreement is
terminated as provided therein, upon the making of certain filings with the
Department of State of the Commonwealth of Pennsylvania pursuant to the PBCL.
At the Effective Time, the Merger Corp. will be merged with and into the
Company, which will be the Surviving Corporation in the Merger, and the
separate corporate existence and identity of the Merger Corp. will cease. The
corporate existence and identity of the Company will continue unaffected by
the Merger, although it will become an affiliate of both Bain Capital and Bear
Stearns.
 
   It is currently contemplated that the Effective Time of the Merger will
occur as promptly as practicable after the approval of the Merger by the
Company's shareholders at the Special Meeting, subject to the conditions
described under "Merger Agreement--Conditions to Merger."
 
   As a result of the Merger, the entire equity interest in the Company will
be owned by the Investors. The shareholders of the Company (other than the
Management Group) will no longer have any interest in, and will not be
shareholders of, the Company, and therefore will not participate in its future
earnings and growth. Instead, each such holder of the Company's common stock
will have the right to receive $21.25 in cash, without interest, for each
share held (other than the Unconverted Shares). Following the Merger, the
Investors will have the opportunity to benefit from any earnings and growth of
the Company, and will bear the risk of any decrease in the Company's value.
Following the Merger, the Company's common stock will no longer be traded on
the Nasdaq National Market, price quotations will no longer be available and
the registration of the Company's common stock under the Exchange Act will be
terminated. After such registration is terminated, the Company will no longer
be required to file periodic reports with the Commission.
   
   At the Effective Time, the present Board of Directors of the Company, other
than Mr. Boreen, will be replaced with individuals selected by Bain Capital
and Bear Stearns and Mr. Tan. Mr. Boreen has agreed to serve as a member of
the Board of Directors as long as he owns at least 50% of the common stock of
the Surviving Corporation he obtained at the Effective Time and the Equity
Investors collectively own at least 51% of the common stock of the Surviving
Corporation. The representatives of Bain Capital who will serve as directors
of the Company as of the Effective Time are David Dominik, Michael A. Krupka,
and Prescott Ashe, and the representative of Bear Stearns who will serve as a
director of the Company as of the Effective Time is John Howard. The officers
of the Company will be the officers of the Surviving Corporation after the
Effective Time. See "Certain Information Concerning Merger Corp. and its
Affiliates."     
 
   The Equity Investors expect that, following consummation of the Merger, the
business and operations of the Company will be continued substantially as they
are currently being conducted. The board of directors and management of the
Company will, however, continue to evaluate the Company's business,
operations, corporate structure and organization and will make such changes as
they deem appropriate.
 
   As a result of the borrowings to be incurred to finance the Merger and the
Company's post-Merger operations, the consolidated indebtedness of the Company
following the Effective Time will be substantially greater than current
levels. In addition, the interest rates on the new indebtedness are expected
to be higher than the Company's current rates, and the covenants applicable to
the new indebtedness are expected to be more restrictive than current
covenants. As a result, the Company's financial and operating flexibility will
be reduced.
 
Financing
   
   The total amount of funds necessary to fund the Merger and related
transactions is expected to be approximately $293.4 million. These funds are
expected to come from the following sources: (i) an equity investment made by
the Equity Investors and certain other investors of approximately $40.0
million, (ii) an     
 
                                      30
<PAGE>
 
equity investment on the part of the Management Group of approximately $10.0
million, consisting primarily of the Converted Shares (valued at $21.25 per
share) and the Converted Options (valued at the equity value of such options),
(iii) cash on-hand at the Effective Time of approximately $60.0 million and
(iv) borrowings by the Company totaling approximately $183.4 million under a
senior secured credit facility and a mezzanine loan facility described below.
 
   Senior Secured Credit Facility. The Equity Investors have obtained a
commitment from Credit Suisse First Boston ("CSFB") to provide the Company
with a senior secured credit facility (the "Senior Facility") in an aggregate
amount of $145 million. The Senior Facility will be comprised of (i) a $120
million term facility, which includes (x) a $50 million term loan tranche
maturing five years from the closing date of the Merger (the "Term A") and (y)
a $70 million term loan tranche maturing seven years from the closing date of
the Merger (the "Term B") and (ii) a $25 million revolving credit facility
(the "Revolver") maturing five years from the closing date of the Merger. The
Revolver will have a sublimit available for the issuance of letters of credit.
 
   The Company will be the borrower under the Senior Facility and all existing
and subsequently acquired/organized domestic subsidiaries of the Company will
guarantee the Senior Facility. In addition, the Senior Facility will be
secured by (i) substantially all of the assets of the Company and its existing
and subsequently acquired/organized domestic subsidiaries and (ii) a pledge of
all of the capital stock of such domestic subsidiaries and 65% of the capital
stock of the Company's material foreign subsidiaries.
 
   The interest rates under the Senior Facility will be, at the Company's
option, either (i) the Base Rate (higher of the prime lending rate or 1/2 of
1% in excess of the Federal funds effective rate) plus a margin or (ii)
Adjusted LIBOR plus a margin. The initial margin on the Term A and Revolver
will be 2% over the Base Rate and 3% over Adjusted LIBOR, and the initial
margin on the Term B will be 2.5% over the Base Rate and 3.5% over Adjusted
LIBOR. These margins will vary according to a pricing grid based upon the
Company's consolidated leverage ratio and on each of the Term A and Revolver,
will range from 1.75%-.75% for Base Rate and from 2.75%-1.75% for Adjusted
LIBOR and on the Term B, will range from 2.25%-2.00% for Base Rate and from
3.25%-3.00% for Adjusted LIBOR.
 
   The documents for the Senior Facility will contain affirmative, negative
and financial covenants and events of default customary for credit facilities
of a size and type similar to the Senior Facility.
 
   The Mezzanine Facility. The Equity Investors have obtained a commitment
from CSFB and The Bear Stearns Companies Inc. ("BSCI") to provide the Company
with up to $47.5 million in senior subordinated mezzanine loans (the
"Mezzanine Facility" and together with the Senior Facility, the "Facilities")
to assist in financing the Merger and related transactions. The Mezzanine
Facility will be made available to the Company, as borrower, and will be
guaranteed by each of the domestic subsidiaries of the Company that guarantees
the Senior Facility. The Mezzanine Facility will mature on the date which is
364 days after the closing of the Merger. If the Mezzanine Facility is not
repaid in full prior to that date, loans thereunder will be exchanged for
exchange notes with registration rights, bearing interest at a rate of 15% per
annum. The exchange notes, if issued, would mature 10 years from the date of
the closing of the Merger.
 
   The Mezzanine Facility will bear interest at a rate of 13% per annum,
increasing by .50% at the end of each quarter until maturity, with an overall
cap on the interest rate of 15% per annum. The Mezzanine Facility will have
affirmative and negative covenants and events of default customary for a
facility of a similar size and type.
 
   The holders of loans under the Mezzanine Facility will receive warrants to
purchase a percentage of common stock of the Company. The number of warrants
received by such holders varies depending upon the amount of time that the
Mezzanine Facility is outstanding (prior to refinancing, resale or conversion
into exchange notes), whether the loans under the Mezzanine Facility have been
sold to other holders or whether such loans have been refinanced with long-
term notes. In any event, the number of warrants issued in connection with the
Mezzanine Facility will not exceed an amount sufficient to purchase up to 7%
of the Company on a fully diluted basis.
 
                                      31
<PAGE>
 
   Conditions to Funding the Facilities. The funding of the Facilities is
subject to the satisfaction of customary conditions for debt financings
including, without limitation, the following:
 
  (i) preparation, execution and delivery of definitive documentation in
      connection with the Facilities;
 
  (ii) satisfaction with material terms and conditions of the agreements
       related to the Merger;
 
  (iii) payment of fees and expenses;
 
  (iv) closing of the Merger prior to June 30, 1999;
 
  (v) delivery of appropriate financial statements of the Company and its
      subsidiaries, including those statements covering the three fiscal-year
      periods most recently ended and delivery of appropriate projections;
      and
 
  (vi) since June 27, 1998, the absence of one or more events, changes or
       effects which would reasonably be expected to have a material adverse
       effect on (x) the business, results of operations, financial condition
       or prospects of the Company and its subsidiaries taken as a whole or
       (y) the validity or enforceability of any of the documents entered
       into in connection with the Merger or the related transactions.
 
Federal Income Tax Consequences
 
   Shareholders who exchange all of their shares of the Company's common stock
for cash pursuant to the Merger or who exercise appraisal rights will
recognize gain or loss equal to the difference between the cash received in
the Merger or pursuant to the exercise of appraisal rights and such
shareholder's adjusted tax basis in the shares exchanged. Gain or loss
recognized will be treated as a capital gain or loss if the shares are held as
capital assets and the shareholder is not a shareholder after the Merger. If
the shares of the Company's common stock that are exchanged have a holding
period of more than one year at the Effective Time, then the capital gain will
be long term. For individuals, the maximum federal income tax rate on long
term capital gain is 20%.
   
   THE FOREGOING PARAGRAPH PRESENTS THE MATERIAL FEDERAL INCOME TAX
CONSEQUENCES OF THE MERGER. THE FOREGOING DISCUSSION DOES NOT DISCUSS TAX
CONSEQUENCES UNDER THE LAWS OF STATES OR LOCAL GOVERNMENTS OR OF ANY OTHER
JURISDICTION OR TAX CONSEQUENCES TO CATEGORIES OF SHAREHOLDERS THAT MAY BE
SUBJECT TO SPECIAL RULES, SUCH AS FOREIGN PERSONS, TAX-EXEMPT ENTITIES,
INSURANCE COMPANIES, FINANCIAL INSTITUTIONS AND DEALERS IN STOCKS AND
SECURITIES. THE FOREGOING DISCUSSION MAY NOT BE APPLICABLE TO A SHAREHOLDER
WHO ACQUIRED SHARES OF THE COMPANY'S COMMON STOCK PURSUANT TO THE EXERCISE OF
STOCK OPTIONS OR OTHERWISE AS COMPENSATION AND DOES NOT ADDRESS THE TAX
CONSEQUENCES OF SHAREHOLDERS WHO WILL HAVE A CONTINUING EQUITY INTEREST IN THE
COMPANY. EACH HOLDER OF SHARES OF THE COMPANY'S COMMON STOCK IS URGED TO
OBTAIN, AND SHOULD RELY UPON, SUCH HOLDER'S OWN TAX ADVICE.     
 
Accounting Treatment
 
   The Company expects that the Merger will be accounted for as a
recapitalization for accounting purposes because it will not constitute a
change of control under generally accepted accounting principles. Under the
recapitalization method of accounting, the historical cost basis of the
Company's assets and liabilities will be carried forward to the Surviving
Corporation with the aggregate cost of repurchasing the common stock accounted
for as a charge to shareholders' equity. The cost of repurchasing and
canceling the outstanding options will be accounted for as compensation
expense by the Surviving Corporation. Neither the obligation of Merger Corp.
to consummate the Merger nor the obligation of the lenders under the
Facilities is conditioned upon the Merger being accounted for as a
recapitalization.

Rights of Dissenting Shareholders
 
   If any holders of the Company's common stock properly exercise appraisal
rights in connection with the Merger under Subchapter 15D of the PBCL, any
shares held by such holders will not be converted into the right to receive
$21.25 per share, but instead will be converted into the right to receive the
"fair value" of such shares pursuant to Subchapter D of Chapter 15 of the
PBCL. See "Appraisal Rights of Dissenting Shareholders."
 
Delisting and Deregistration of Common Stock
 
   Following the Merger, the Company's common stock will be no longer traded
on the Nasdaq National Market, price quotations will no longer be available
and the registration of the Company's common stock under the Exchange Act will
be terminated. After such registration is terminated, the Company will no
longer be required to file periodic reports with the Commission.
 
Certain Regulatory Matters
 
   Consummation of the Merger is conditioned upon receipt by Merger Corp. and
the Company of such regulatory and other approvals as are required under
applicable law. Other than matters described below, Merger Corp. and the
Company know of no such regulatory or other approvals required by law.
 
   Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR
Act"), certain acquisition transactions may not be consummated unless certain
information has been furnished to the Federal Trade Commission (the "FTC") and
the Antitrust Division of the Justice Department (the "Antitrust Division")
and certain waiting period requirements have expired or been terminated.
Merger Corp. and the Company are each reviewing whether the proposed Merger is
subject to the notification and reporting requirements of the HSR Act.

                             THE MERGER AGREEMENT
 
Overview
 
   The terms and conditions of the Merger are set forth in the Merger
Agreement, the text of which is attached to this Proxy Statement as Appendix
A. The summary of the Merger Agreement contained in this Proxy Statement does
not purport to be complete and is qualified in its entirety by reference to
the complete text of such document.
 
   At the time the Merger becomes effective, the Merger Corp. will be merged
with and into the Company in accordance with the PBCL. As a result of the
Merger, the separate corporate existence of the Merger Corp. (which was formed
solely for the purposes of the Merger and has not engaged in any operations or
business) will cease, and the corporate existence and identity of the Company
will continue, unaffected by the Merger.
 
   Upon the consummation of the Merger, each share of the Company's common
stock (other than the Unconverted Shares) will be converted into the right to
receive $21.25 in cash, without interest.
 
Exchange of Certificates Representing Common Stock
 
   Instructions with regard to the surrender of the Company's stock
certificates, together with a letter of transmittal to be used for this
purpose, will be mailed to the Company's shareholders as promptly as
practicable after the Effective Time. In order to receive the Merger
Consideration, the shareholders of the Company will be required to surrender
their stock certificates after the Effective Time, together with a duly
completed and executed letter of transmittal, to a paying agent (the "Paying
Agent") selected by Bain Capital and Bear Stearns. Promptly after the
Effective Time, the cash amount of the Merger Consideration will be deposited
in trust with the Paying Agent. Upon receipt of such stock certificates and
letter of transmittal, the Paying Agent will deliver the Merger Consideration
to the registered holder or his transferee of the shares of the Company's
common stock. No interest will be paid or accrued on the amounts payable upon
the surrender of stock certificates.
 
   SHAREHOLDERS SHOULD NOT SUBMIT THEIR STOCK CERTIFICATES FOR EXCHANGE UNTIL
THE INSTRUCTIONS AND LETTER OF TRANSMITTAL ARE RECEIVED.
 
   If the Merger Consideration is to be delivered to a person other than the
person in whose name the certificate for the shares of the Company's common
stock surrendered in exchange therefor is registered, it will be a condition
of such payment of such Merger Consideration that the stock certificate so
surrendered be properly endorsed and otherwise in proper form for transfer,
and that the person requesting such payment (i) pay in advance 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 stock certificate surrendered
or (ii) establish to the satisfaction of the Paying Agent that such tax has
been paid or is not applicable.
 
   After the Effective Time, there will be no further transfers on the stock
transfer books of the Company of the shares of the Company's common stock that
were outstanding immediately prior to the Effective Time. If a certificate
representing such shares is presented for transfer, subject to compliance with
the requisite transmittal procedures, it will be canceled and exchanged for
the Merger Consideration.
 
   Each certificate representing shares of the Company's common stock
immediately prior to the Effective Time (other than the Unconverted Shares)
will, at the Effective Time, be deemed for all purposes to represent only the
right to receive the Merger Consideration into which the shares of the
Company's common stock represented by such certificate were converted in the
Merger.
 
   Any Merger Consideration delivered or made available to the Paying Agent
and not exchanged for stock certificates within 180 days after the Effective
Time will be returned by the Paying Agent to the Company, which will
thereafter act as Paying Agent. None of Bain, Bear Stearns, the Company or the
Paying Agent will be liable to a holder of shares of the Company's common
stock for any of the Merger Consideration delivered to a public official
pursuant to applicable abandoned property, escheat or similar laws.

Treatment of Outstanding Options
 
   The Merger Agreement provides that holders of options (other than the
Converted Options), whether or not such options are exercisable, will be
entitled to receive (subject to applicable withholding taxes) an amount in
cash equal to the product of (i) the difference between $21.25 and the
exercise price of such option and (ii) the number of shares of the Company's
common stock subject to such option. As of February 12, 1999, there were
options outstanding to purchase an aggregate of 2,325,484 shares of the
Company's common stock at a weighted average exercise price of $15.00 per
share. The members of the Management Group will not receive this option
consideration with respect to the Converted Options, which will be converted
into options to purchase common stock of the Surviving Corporation. See
"Special Factors--Conflicts of Interest."
 
Representations and Warranties
 
   The Merger Agreement contains various representations and warranties of the
parties, including representations and warranties by the Company with respect
to its corporate existence and power, capital structure, corporate
authorization, noncontravention, consents and approvals, SEC filings,
information supplied, compliance with applicable laws, litigation, taxes,
pension and benefit plans and ERISA, absence of certain changes or events,
absence of undisclosed material liabilities, opinion of financial advisor,
vote required, labor matters, intangible property, environmental matters, real
property, board recommendation, material contracts, related party
transactions, indebtedness, liens, and other matters.
 
   Merger Corp. has also made certain representations and warranties with
respect to corporate existence and power, corporate authorization,
noncontravention, financing, beneficial ownership of shares, information
supplied, litigation, and other matters.

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,

$2,500,000 per annum; (iii) sell, lease, license, mortgage or otherwise

or any rights, warrants, calls, commitments or options to acquire, any such
shares, voting securities or convertible 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); (viii) 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,
employment or other employee benefit agreement, trust, plan or other

                                      35

any of its subsidiaries or increase in any manner the compensation or fringe
benefits of any director, officer or employee of the Company or any of its
subsidiaries or pay any benefit not required by any existing agreement or

derivative suits arising out of the transactions contemplated by the Merger
Agreement or any other litigation or settle, pay or compromise any claims not
required to be paid, except 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 Merger Corp.
 
No Solicitation
 
   The Merger Agreement provides that neither the Company nor any of its
representatives will directly or indirectly (i) initiate, solicit, or
encourage or take any other action to facilitate any inquires or proposals
that constitute, or could reasonably be expected to lead to, any 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 the foregoing restrictions shall not apply to persons to
whom the Company or any of its representatives have already provided, within
the three months prior the Merger Agreement, non-public written information
about the Company to facilitate an Acquisition Proposal; (iii) agree to or
endorse any Acquisition Proposal; or (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 the Merger
Agreement.
 
   Prior to the approval of the Merger by the shareholders of the Company, the
Merger Agreement does not prohibit the Board 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 if it would constitute a Higher
Offer, (B) failing to make, withdrawing or modifying its recommendation that
the shareholders of the Company approve the Merger and (C) disclosing to the
shareholders the terms of a tender offer. Within five days of accepting the
Higher Offer, the Company Board must notify Merger Corp. The exercise of its
rights under clause (A), (B) or (C) above shall not constitute a breach by the
Company of the Merger Agreement.
 
Indemnification
 
   The Merger Agreement provides that the Company will, from and after the
Effective Time, 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 ("Indemnified
Liabilities") (i) to the full extent permitted by the PBCL or, if the
protections afforded thereby to an Indemnified Party 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 and by-laws and agreements in effect at the date hereof, which
provisions will survive the Merger and continue in full force and effect after
the Effective Time. The Company will pay expenses in advance of the final
disposition of any such action or proceeding to each Indemnified Party to the
full extent permitted by law.
 
   All rights to indemnification, including provisions relating to advances of
expenses incurred in defense of any action or suit, existing in favor of the
Indemnified Parties shall survive the consummation of the Merger at the
Effective Time, are intended to benefit the Company and the Indemnified
Parties, shall be binding on all successors and assigns of Merger Corp. and
shall be enforceable by the Indemnified Parties.
 
Directors' and Officers' Insurance
 
   For a period of six years after the Effective Time, the Company shall cause
to be maintained in effect the current policies of directors' and officers'
liability insurance maintained by the Company (provided that after the
 
                                      36
<PAGE>
 
Effective Time, the Company may substitute therefor other policies of at least
the same coverage amounts and containing terms and conditions not less
advantageous to the beneficiaries of the current policies). After the
Effective Time, the Company shall not be required to pay an annual premium for
such insurance in excess of 200% of the last annual premium paid by the
Company prior to the date of the Merger Agreement but in such case shall
purchase as much coverage as possible for such amount.
 
Conditions to the Merger
   
   Each party's obligation to effect the Merger is subject to the satisfaction
of a number of conditions, most of which may be waived by a specified party or
parties. These conditions include the Merger Agreement and the Merger being
approved and adopted by a majority of the votes cast by the holders of the
Company's common stock as of the Record Date and no temporary restraining
order, preliminary or permanent injunction or other order issued by any court
of competent jurisdiction or other legal restraint or prohibition preventing
the consummation of the Merger being in effect. If the Company waives a
material condition to the Merger, it will then consider resoliciting
shareholder approval of the Merger. The decision whether to resolicit
shareholder approval will depend upon whether a shareholder could reasonably
be expected to take into account the waiver of the condition in deciding how
to vote on the Merger.     
 
   In addition, the obligations of the Merger Corp. to effect the Merger are
subject to the satisfaction of additional conditions, which include the
following: (i) the representations and warranties of the Company in the Merger
Agreement are true and correct as of the Effective Time, except as otherwise
contemplated by the Merger Agreement and except in those instances where the
aggregate amounts represented by all breaches (other than breaches for which
the Company has obtained the consent of the Merger Corp.) of such
representations and warranties are not likely to result in a material adverse
effect on the Company; (ii) the Company shall have performed its obligations
under the Merger Agreement in all material respects at or prior to the
Effective Time; (iii) Merger Corp. shall have received evidence of all
licenses, permits, consents and approvals as set forth in the Merger
Agreement; (iv) the absence of any pending legal action by any governmental
entity, or by any person other than a governmental entity which has a
reasonable likelihood of success, seeking to restrain or prohibit the
completion of the Merger; and (v) the Company shall have received the proceeds
of the debt financing for the transactions contemplated by the Merger
Agreement on terms substantially as outlined in the financing commitment
letter obtained by Bain Capital and Bear Stearns in connection with the
execution of the Merger Agreement or involving such other financing sources as
are reasonably acceptable to Bain Capital and Bear Stearns.
 
   In addition, the obligation of the Company to effect the Merger is subject
to the satisfaction of certain additional conditions which include the
representations and warranties of the Merger Corp. set forth in the Merger
Agreement being true and correct as of the Effective Time, except as otherwise
contemplated by the Merger Agreement.
 
Termination of Merger Agreement
 
   The Merger Agreement may be terminated and the Merger abandoned, at any
time prior to the Effective Time, whether before or after the approval by the
Company's shareholders, (i) by the mutual written consent of Merger Corp. and
the Company; (ii) by Merger Corp. or the Company if the Merger shall not have
been consummated on or before June 30, 1999; but neither Merger Corp. nor the
Company may terminate the Merger Agreement at such time if such party has
materially breached the Merger Agreement; (iii) by either Merger Corp. or the
Company if the consummation of the Merger would violate any nonappealable
final order, decree or ruling of any court or governmental body or agency
having competent jurisdiction; (iv) by Merger Corp. if the Board of Directors
of the Company (x) fails to recommend or modifies or withdraws its
recommendation to the shareholders that they approve the Merger, (y) approves
or recommends an Acquisition Proposal or (z) resolves to do any of the
foregoing or otherwise materially impedes approval of the Merger by the
shareholders; (v) by the Company if any person has made a bona fide proposal
relating to an Acquisition Proposal or has commenced
 
                                      37
<PAGE>
 
a tender or exchange offer for the Company's common stock and the Board of
Directors of the Company determines in good faith (A) after consultation with
its financial advisors, that such transaction constitutes a Higher Offer and
(B) 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 owed only to shareholders; however, termination of the Merger
Agreement by the Company on such grounds will not be treated as a violation of
any other obligation of the Company; or (vi) by either Merger Corp. or the
Company if the shareholders do not approve the Merger at a duly held meeting
of shareholders or at any adjournment or postponement thereof.
 
   If Merger Corp. or the Company terminates the Merger Agreement as provided
above, there will be no liability on the part of any party or its officers,
directors or shareholders, except as described in "Fees and Expenses" below.
 
Amendment of the Merger Agreement; Waiver of Conditions
 
   The Merger Agreement may be amended by the Merger Corp. and the Company by
written agreement at any time before or after the approval of the Merger
Agreement by the Company's shareholders, provided that after such shareholder
approval no amendment or modification may be made without the further approval
of such shareholders that decreases the Merger Consideration or that the Board
of Directors of the Company determines would adversely affect the rights of
the Company's shareholders. Each party may, to the extent legally permitted,
extend the time for the performance of any of the obligations of the other
party, waive any inaccuracies in the representations or warranties of the
other contained in the Merger Agreement or in any other writing delivered
pursuant to the Merger Agreement or waive compliance by the other with any
agreements or conditions contained in the Merger Agreement.
 
Fees and Expenses
 
   The Merger Agreement provides that all costs and expenses in connection
with the Merger Agreement and the transactions contemplated thereby shall be
paid by the party incurring such expense whether or not the Merger is
consummated except as otherwise provided in the Merger Agreement and except
with respect to claims for damages incurred as a result of the breach of the
Merger Agreement. In addition, the Company has agreed to pay Merger Corp. a
fee equal to $6,000,000 ("Termination Fee") if the Company consummates or
agrees to consummate a Business Combination within 12 months of the
termination of the Merger Agreement and the Merger Agreement is terminated (a)
pursuant to paragraph (v) or (vi) in the Section immediately above entitled
"Termination of the Merger Agreement;" or (b) by Merger Corp. pursuant to
paragraph (ii) or (iv) in the Section immediately above entitled "Termination
of the Merger Agreement." In the event the Termination Fee becomes payable, it
must be paid in cash by wire transfer within three business days following the
consummation of a Business Combination.
 
   If the Merger Agreement is terminated for any reason other than (i) on
account of any of certain customary conditions in the Merger Agreement not
being satisfied, (ii) primarily as a result of material adverse changes in the
economy or industry occurring after the date of the Merger Agreement or
(iii) solely on account of Merger Corp.'s failure to obtain the financing as
set forth in the Merger Agreement, the Company has agreed to reimburse Merger
Corp. for all out-of-pocket expenses and fees incurred prior to, on or after
the date of the Merger Agreement in connection with the Merger and the
consummation of all transactions contemplated thereby up to $3 million.

                  APPRAISAL RIGHTS OF DISSENTING SHAREHOLDERS
 
   If the Merger is consummated, shareholders who fully comply with the
statutory procedures for exercising appraisal rights set forth in the PBCL
will be entitled to receive cash for the fair value of their common stock as
determined pursuant to the procedures prescribed by the PBCL. Merely voting
against the Merger Agreement will not perfect a shareholder's appraisal
rights. Shareholders are urged to review carefully the dissenting
shareholders' rights provisions of the PBCL, a description of which is
provided below and the full text of which is attached to this Proxy Statement
as Appendix C and incorporated herein by reference. SHAREHOLDERS WHO FAIL TO
COMPLY STRICTLY WITH THE APPLICABLE PROCEDURES WILL FORFEIT THEIR APPRAISAL
RIGHTS IN CONNECTION WITH THE MERGER.
 
   Sections 1571-80 of the PBCL ("Subchapter D"), 1906 and 1930 of the PBCL,
copies of which are attached to this Proxy Statement as Appendix C, entitle
any holder of record of common stock who objects to the Merger, in lieu of
receiving the consideration for such common stock provided under the Merger
Agreement, to demand in writing that he be paid in cash the fair value of his
common stock. Section 1572 of the PBCL defines "fair value" as: "The fair
value of shares immediately before the effectuation of the corporate action to
which the dissenter objects, taking into account all relevant factors, but
excluding any appreciation or depreciation in anticipation of the corporate
action."
 
   Any shareholder contemplating making demand for fair value is urged to
review carefully the provisions of Subchapter D, particularly the procedural
steps required to perfect his appraisal rights thereunder. APPRAISAL RIGHTS
WILL BE LOST IF THE PROCEDURAL REQUIREMENTS OF SUBCHAPTER D ARE NOT FULLY AND
PRECISELY SATISFIED. The following summary does not purport to be a complete
statement of the provisions of Subchapter D of the PBCL and is qualified in
its entirety by reference to Appendix C and the PBCL.
 
   Filing Notice of Intention to Demand Fair Value. If you wish to exercise
your appraisal right or to preserve the right to do so, then before the vote
of the shareholders is taken on the Merger you must deliver to the Company a
written notice of intention to demand that you be paid the fair value of your
common stock if the Merger is effected. Such written notice must be sent to
Rudolf Gassner, the Chairman of the Company, at Integrated Circuit Systems,
Inc., 2435 Boulevard of the Generals, Norristown, PA 19403. A vote against the
Merger is not sufficient to satisfy the requirement of delivering a written
notice to the Company. In addition, you must continuously hold your common
stock from the date of filing the notice with the Company through the
consummation of the Merger, and you must not vote your common stock in favor
of the Merger. Your failure to comply with any of the foregoing will result in
the forfeiture of any right to payment of fair value for your common stock.
Once the demand has been properly made, the determination of "fair value" will
be made pursuant to the provisions of Pennsylvania law, including an ultimate
court determination if applicable.
 
   Notice to Demand Payment. If the Merger is approved by the shareholders,
the Company will mail you a further notice if you gave due notice of your
intention to exercise your statutory appraisal right and you refrained
 
                                      39
<PAGE>
 
from voting in favor of the Merger. This notice will provide you with certain
instructions for demanding payment and will notify you of a date by which such
right must be exercised.
 
   Record Owners and Beneficial Owners. If you are a record holder of common
stock held in whole or in part for the benefit of another person, you may
assert appraisal rights as to fewer than all of the common stock registered in
your name only if you dissent with respect to all the common stock
beneficially owned by such person and disclose the name and address of the
person or persons on whose behalf you dissent. If you are a beneficial owner
of common stock and are not the record holder, you may assert appraisal rights
with respect to common stock held on your behalf if you submit to the Company
the written consent of the record holder not later than the time of assertion
of appraisal rights. If you are a beneficial owner, you may not dissent with
respect to fewer than all of your common stock, whether or not such common
stock is registered in your name.

                 SHAREHOLDER PROPOSALS FOR 1999 ANNUAL MEETING
 
   Due to the contemplated consummation of the Merger, the Company does not
currently expect to hold a 1999 Annual Meeting of Shareholders because,

the Company at least 50 days and not more than 75 days prior to the date of

Company's by-laws relating to advance notice of shareholder proposals in order
to be eligible for consideration by shareholders at such meeting. Any such

considered for inclusion in the Company's proxy materials for the 1999 Annual
Meeting of Shareholders. In addition, the execution of a proxy solicited by
the Company in connection with the 1999 Annual Meeting of Shareholders shall
confer on the designated proxy holder discretionary voting authority to vote
on any shareholder proposal which is not included in the Company's proxy
materials and for which the Company has not received notice at least 50 days
and not more than 75 days prior to the date of such meeting.

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.
 
                                      A-2

     (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 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 record holder of certificates (the "Certificates") that
immediately prior to the Effective Time represented Common Shares a form of
letter of
 
                                      A-3
<PAGE>
 
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.
 
   (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.
 
                                      A-4
<PAGE>
 
   (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) 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
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

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
 
                                      A-6
<PAGE>
 
accelerate the performance 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 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 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").
 
                                      A-8
<PAGE>
 
   (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

violate in any material respect any instrument of record or agreement

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
over the Real Property, the absence of which could have a Material Adverse
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.
 
   Section 3.25 Absence of Certain Changes or Events with Respect to the
Company. Except as set forth in Section 3.13 of the Disclosure Schedule, since
June 27, 1998, the Company has not (a) suffered a Material Adverse Effect or
(b) materially changed the Company's accounting principles, practices,
articles or methods, except as required by generally accepted accounting
principles or applicable law.
 
                                   ARTICLE 4
 
                     Representations and Warranties of ICS
 
   ICS represents and warrants to the Company as follows:
 
   Section 4.1 Organization and Qualification. ICS is a corporation duly
organized, validly existing and in good standing under the laws of its state
or jurisdiction of incorporation and is in good standing as a foreign
corporation in each other 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 ICS. The term "Material Adverse Effect on ICS", as used in
this Agreement, means any change in or effect on the 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.
 
                                     A-16
<PAGE>
 
   (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.
 
   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.
 
   Section 4.6 Pennsylvania Law. ICS was not immediately prior to the
execution of this Agreement, an "interested stockholder" within the meaning of
Sections 2538 and 2553 of the BCL.
 
   Section 4.7 Beneficial Ownership of Shares. As of the date hereof, 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
 
                                     A-17
<PAGE>
 
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.
 
                                   ARTICLE 5
 
                                   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 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):

  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, employment or
  other employee benefit agreement, trust, plan or other arrangement for the
  benefit or welfare of any director, officer or employee of the Company or
  any of its Subsidiaries or increase in any manner the compensation or
  fringe benefits of any director, officer or employee of the Company or any
  of its Subsidiaries or pay any benefit not required by any existing
  agreement or place any assets in any trust for the benefit of any director,
  officer or employee of the Company or any of its Subsidiaries (in each
  case, except with respect to employees and directors in the ordinary 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 subject to
  any Lien or otherwise dispose of any of its properties or assets other than
  immaterial properties or assets (or immaterial portions of 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 other
  distributions in respect of, any of its capital stock (except (A) for
  dividends paid by Subsidiaries to the Company with respect to capital
  stock), (y) split, combine or reclassify any of its capital stock or issue
  or authorize the issuance of any other securities in respect of, in lieu of
  or in substitution for shares of its capital stock or (z) purchase, redeem
  or otherwise acquire any shares of capital stock of the Company or any of
  its Subsidiaries or any other securities thereof or any rights, warrants or

  options, warrants, commitments, subscriptions, rights to 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 other
  voting securities or any securities convertible into, or any rights,
  warrants, calls, commitments or options to acquire, any such shares, voting
  securities or convertible 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);
 
                                     A-18
<PAGE>
 
     (g) amend its Articles of Incorporation, as amended, By-Laws or
  equivalent organizational documents or alter through merger, liquidation,
  reorganization, restructuring or in any other fashion the corporate
  structure or ownership of any Subsidiary of the Company;
 
     (h) make or agree to make any acquisition of assets which is material to
  the Company and its Subsidiaries, taken as a whole, except for (x)
  purchases of inventory in the ordinary course of business or (y) pursuant
  to purchase orders entered into in the ordinary course of business which do
  not call for payments in excess of $2,500,000 per annum;
 
     (i) settle or compromise any shareholder derivative suits arising 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.
 
                                     A-19
<PAGE>
 
   (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 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, 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.
 
                                     A-21
<PAGE>
 
   (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:
 
     (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;
 
                                     A-22
<PAGE>
 
     (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 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

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

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

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

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

                   Conditions to Consummation of the Merger
 
   Section 6.1 Conditions. The respective obligations of ICS and the Company
to consummate the Merger are subject to the satisfaction, at or before the
Effective Time, of each of the following conditions:
 
     (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.
 
                                     A-24
<PAGE>
 
     (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 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
 
                                     A-25
<PAGE>
 
  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.
 
     (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).

                        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
 
                                     A-26
<PAGE>
 
  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;
 
     (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

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"), 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
 
                                     A-27

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.

supersede all prior agreements and understandings, both written and oral,
among the parties with respect to the subject matter hereof and thereof.
 
   (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

                AMENDMENT NO. 1 TO AGREEMENT AND PLAN OF MERGER
 
   AMENDMENT No. 1 (this "Amendment"), dated February 16, 1999, by and among
Integrated Circuit Systems, Inc., a Pennsylvania corporation (the "Company"),
and ICS Merger Corp., a Pennsylvania corporation ("ICS"). All capitalized
terms used herein and not otherwise defined shall have the respective meanings
provided such terms in the Merger Agreement (as defined below).
 
                                  WITNESSETH:
 
   WHEREAS, the Company and ICS are parties to a certain Agreement and Plan of
Merger dated January 20, 1999 (the "Merger Agreement"); and
 
   WHEREAS, the parties hereto wish to amend the Merger Agreement as herein
provided;
 
   NOW, THEREFORE, it is agreed:
 
     1. Section 1.1 of the Merger Agreement is hereby amended to insert in
  the first sentence the words "(including Section 1906 thereof, which shall
  be applicable to the transactions contemplated hereby,)" after the words
  "this Agreement and the BCL" and before the words "at the Effective Time".
 
     2. Section 2.1(b)(ii) of the Merger Agreement is hereby amended to
  delete the date "February 10, 1999" from the end of that Section and to
  insert the date "March 3, 1999" in lieu thereof.
 
     3. Section 2.2 of the Merger Agreement is hereby deleted in its entirety
  and the following new Section 2.2 shall be inserted in lieu thereof.
 
    "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 1992 Stock Option Plan and 1997 Equity
    Compensation Plan (the "Stock Plans") and all other outstanding
    options, in each case as reflected in Section 3.2 of the Disclosure
    Schedule, will be entitled to receive in settlement of such Option (a)
    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 (the "Option Spread"), (b) new stock options ("New Options") in
    the Company pursuant to new stock option agreements between the
    Company, ICS and certain members of Management or (c) some combination
    of (a) and (b) above. 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 or
    New Options 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."
 
     4. Section 3.2 of the Merger Agreement is hereby amended to delete the
  second full sentence and the following new sentence shall be inserted in
  lieu thereof.

    Shares were issued and outstanding, all of which are entitled to vote
    on this Agreement. "

    any non-public confidential information about the Company and its
    Subsidiaries in a manner consistent with market practice for
    acquisition financing transactions, reasonable access, upon reasonable

    request.
 
    In addition, the Company agrees that so long as the Financing Sources
    and the representatives agree in writing (with the Company as a party
    or expressly set forth as a third party beneficiary to such agreement)
    to maintain the confidentiality of any non-public confidential
    information about the Company and its Subsidiaries in a manner
    consistent with market practice for acquisition financing transactions,
    ICS and the ICS Representatives may directly furnish financial and
    operating data and such other information about the Company and its

    between Bear Stearns Merchant Fund Corp. and the Company and the letter
    agreement dated May 15, 1998, between Bain Capital Inc. and the Company
    (the "Confidentiality Agreements")."

                  [Letterhead of Pennsylvania Merchant Group]
January 19, 1999
 
The Special Committee of the Board of Directors and
The Board of Directors
Integrated Circuit Systems, Inc.
2435 Boulevard of the Generals
P.O. Box 968
Valley Forge, PA 19482-0968
 
Gentlemen:
 
We understand that Integrated Circuit Systems, Inc. ("ICS" or the "Company") is
considering entering into a transaction with Bain Capital, Inc., Bear Stearns &
Co. and current members of management (collectively, the "Buyout Group")
pursuant to which ICS would merge with an entity formed by the Buyout Group
and, as part of the merger, each outstanding share of common stock of ICS,
other than certain shares held by members of management (the "Rollover
Series"), will be exchanged for $21.25 in cash (the "Proposed Transaction").
The holders of shares which are not Rollover Shares are referred to herein as
"Unaffiliated Shareholders".
 
We have been requested by the Special Committee of the Board of Directors of
the Company to render our opinion with respect to the fairness, from a
financial point of view, to the Company's Unaffiliated Shareholders of the
consideration to be offered to such Unaffiliated Shareholders in the Proposed
Transaction. We have not been requested to opine as to, and our opinion does
not in any manner address, the Company's underlying business decision of
whether or not to proceed with or effect the Proposed Transaction.
 
In conducting our analysis and arriving at our opinion as expressed herein, we
have reviewed a draft of the Agreement and Plan of Merger between ICS and the
Buyout Group dated January 19, 1999. Additionally, we have held discussions
with certain senior officers of ICS concerning the business, operations and
prospects of ICS. We have also reviewed and analyzed all publicly available
business and financial information relating to ICS that we believe to be
relevant to our inquiry, as well as certain financial forecasts and other data
for ICS which were provided to or otherwise discussed with us by the management
of ICS. We also reviewed, among other things, current and historical market
prices and trading volumes of the Common Stock. Based upon the projected
financial performance, we have made certain estimates as to the future cash
flows and terminal values, and, after applying a range of appropriate discount
rates, the present value of such cash flows and terminal value, which analysis
is defined as a "Discounted Cash Flow Analysis". We also analyzed certain
financial, stock market and other publicly available information relating to
the business of other companies whose operations we considered relevant in
evaluating those of ICS. Furthermore, we examined the terms of certain business
combinations which we believe to be relevant and compared the terms to the
Proposed Transaction. In addition to the foregoing, we conducted such other
analyses and examinations and considered such other financial, economic and
market criteria as we deemed appropriate in arriving at our valuation.
 
In rendering our opinion, we have assumed and relied, without independent
verification, upon the accuracy and completeness of all financial and other
information and data publicly available or furnished to or otherwise reviewed
by or discussed with us and have further relied upon the assurances of the
management of ICS that they are not aware of any facts that would make such
information inaccurate or misleading. With respect to financial forecasts and
other information and data provided to or otherwise reviewed by or discussed
with us,
 
                                      B-1
<PAGE>
 
we have been advised by the management of ICS that such forecasts and other
information and data were reasonably prepared on bases reflecting the best
currently available estimates and judgments of the management of ICS as to the
future financial performance of ICS. We have not made or been provided with an
independent evaluation or appraisal of the assets, liabilities (contingent or
otherwise) or reserves of ICS nor have we made any physical inspection of the
properties or assets of ICS. Our opinion is necessarily based upon information
available to us, and financial, stock market and other conditions and
circumstances existing and disclosed to us, as of the date hereof.
 
Based upon and subject to the foregoing, we are of the opinion as of the date
hereof that, from a financial point of view, the consideration to be offered
to the Unaffiliated Shareholders of the Company in the Proposed Transaction
is, as of the date of this letter, fair to such Unaffiliated Shareholders.
This opinion is for the use and benefit of the Special Committee of the Board
of Directors of the Company and the Board of Directors of the Company and is
rendered to the Special Committee of the Board of Directors and the Board of
Directors in connection with its consideration of the Proposed Transaction.
 
We have acted as financial advisor to the Special Committee of the Board of
Directors in connection with its evaluation of the Proposed Transaction and
will receive a fee for our services, a portion of which is contingent upon the
closing of the Proposed Transaction or a similar transaction with a person or
entity other than the Buyout Group. In addition, the Company has agreed to
indemnify us for certain liabilities that may arise out of the rendering of
this opinion. We also have performed various investment banking services for
the Company in the past (including acting as sole manager of the Company's
initial public offering and as co-manager of a secondary offering) and have
received customary fees for such services. In the ordinary course of our
business, we and our affiliates may actively trade or hold the securities of
ICS for our own account or for the account of our customers and, accordingly,
may at any time hold a long or short position in such securities.
 
Very truly yours,

otherwise, with or without assuming the liabilities of the other corporation
and with or without the intervention of another corporation or other person,
shall not be entitled to the rights and remedies of dissenting shareholders
provided in this subchapter regardless of the fact, if it be the case, that
the acquisition was accomplished by the issuance of voting shares of the
corporation to be outstanding immediately after the acquisition sufficient to
elect a majority or more of the directors of the corporation.
 
   (c) Grant of optional dissenters rights.--The bylaws or a resolution of the
board of directors may direct that all or a part of the shareholders shall
have dissenters rights in connection with any corporate action or other
transaction that would otherwise not entitle such shareholders to dissenters
rights.
 
   (d) Notice of dissenters rights.--Unless otherwise provided by statute, if
a proposed corporate action that would give rise to dissenters rights under
this subpart is submitted to a vote at a meeting of shareholders, there shall
be included in or enclosed with the notice of meeting:
 
      (1) A statement of the proposed action and a statement that the
  shareholders have a right to dissent and obtain payment of the fair value
  of their shares by complying with the terms of this subchapter; and
 
      (2) A copy of this subchapter.
 
   (e) Other statutes.--The procedures of this subchapter shall also be
applicable to any transaction described in any statute other than this part
that makes reference to this subchapter for the purpose of granting dissenters
rights.
 
   (f) Certain provisions of articles ineffective.--This subchapter may not be
relaxed by any provision of the articles.
 
   (g) Cross references.--See sections 1105 (relating to restriction on
equitable relief), 1904 (relating to de facto transaction doctrine abolished)
and 2512 (relating to dissenters rights procedure).
 
   (S) 1572. DEFINITIONS
 
   The following words and phrases when used in this subchapter shall have the
meanings given to them in this section unless the context clearly indicates
otherwise:
 
   "Corporation." The issuer of the shares held or owned by the dissenter
before the corporate action or the successor by merger, consolidation,
division, conversion or otherwise of that issuer. A plan of division may
designate which of the resulting corporations is the successor corporation for
the purposes of this subchapter. The successor corporation in a division shall
have sole responsibility for payments to dissenters and other liabilities
under this subchapter except as otherwise provided in the plan of division.
 
   "Dissenter." A shareholder or beneficial owner who is entitled to and does
assert dissenters rights under this subchapter and who has performed every act
required up to the time involved for the assertion of those rights.
 
   "Fair value." The fair value of shares immediately before the effectuation
of the corporate action to which the dissenter objects, taking into account
all relevant factors, but excluding any appreciation or depreciation in
anticipation of the corporate action.
 
                                      C-2
<PAGE>
 
   "Interest." Interest from the effective date of the corporate action until
the date of payment at such rate as is fair and equitable under all the
circumstances, taking into account all relevant factors, including the average
rate currently paid by the corporation on its principal bank loans.
 
   (S) 1573. RECORD AND BENEFICIAL HOLDERS AND OWNERS.--
 
   (a) Record holders of shares.--A record holder of shares of a business
corporation may assert dissenters rights as to fewer than all of the shares
registered in his name only if he dissents with respect to all the shares of
the same class or series beneficially owned by any one person and discloses
the name and address of the person or persons on whose behalf he dissents. In
that event, his rights shall be determined as if the shares as to which he has
dissented and his other shares were registered in the names of different
shareholders.
 
   (b) Beneficial owners of shares.--A beneficial owner of shares of a
business corporation who is not the record holder may assert dissenters rights
with respect to shares held on his behalf and shall be treated as a dissenting
shareholder under the terms of this subchapter if he submits to the
corporation not later than the time of the assertion of dissenters rights a
written consent of the record holder. A beneficial owner may not dissent with
respect to some but less than all shares of the same class or series owned by
the owner, whether or not the shares so owned by him are registered in his
name.
 
   (S) 1574. NOTICE OF INTENTION TO DISSENT.--
 
   If the proposed corporate action is submitted to a vote at a meeting of
shareholders of a business corporation, any person who wishes to dissent and
obtain payment of the fair value of his shares must file with the corporation,
prior to the vote, a written notice of intention to demand that he be paid the
fair value for his shares if the proposed action is effectuated, must effect
no change in the beneficial ownership of his shares from the date of such
filing continuously through the effective date of the proposed action and must
refrain from voting his shares in approval of such action. A dissenter who
fails in any respect shall not acquire any right to payment of the fair value
of his shares under this subchapter. Neither a proxy nor a vote against the
proposed corporate action shall constitute the written notice required by this
section.
 
   (S) 1575. NOTICE TO DEMAND PAYMENT.--
 
   (a) General rule.--If the proposed corporate action is approved by the
required vote at a meeting of shareholders of a business corporation, the
corporation shall mail a further notice to all dissenters who gave due notice
of intention to demand payment of the fair value of their shares and who
refrained from voting in favor of the proposed action. If the proposed
corporate action is to be taken without a vote of shareholders, the
corporation shall send to all shareholders who are entitled to dissent and
demand payment of the fair value of their shares a notice of the adoption of
the plan or other corporate action. In either case, the notice shall:
 
      (1) State where and when a demand for payment must be sent and
  certificates for certificated shares must be deposited in order to obtain
  payment.
 
      (2) Inform holders of uncertificated shares to what extent transfer of
  shares will be restricted from the time that demand for payment is
  received.
 
      (3) Supply a form for demanding payment that includes a request for
  certification of the date on which the shareholder, or the person on whose
  behalf the shareholder dissents, acquired beneficial ownership of the
  shares.
 
      (4) Be accompanied by a copy of this subchapter.
 
   (b) Time for receipt of demand for payment.--The time set for receipt of
the demand and deposit of certificated shares shall be not less than 30 days
from the mailing of the notice.
 
                                      C-3
<PAGE>
 
   (S) 1576. FAILURE TO COMPLY WITH NOTICE TO DEMAND PAYMENT, ETC.--
 
   (a) Effect of failure of shareholder to act.--A shareholder who fails to
timely demand payment, or fails (in the case of certificated shares) to timely
deposit certificates, as required by a notice pursuant to section 1575
(relating to notice to demand payment) shall not have any right under this
subchapter to receive payment of the fair value of his shares.
 
   (b) Restriction on uncertificated shares.--If the shares are not
represented by certificates, the business corporation may restrict their
transfer from the time of receipt of demand for payment until effectuation of
the proposed corporate action or the release of restrictions under the terms
of section 1577(a) (relating to failure to effectuate corporate action).
 
   (c) Rights retained by shareholder.--The dissenter shall retain all other
rights of a shareholder until those rights are modified by effectuation of the
proposed corporate action.
 
   (S) 1577. RELEASE OF RESTRICTIONS OR PAYMENT FOR SHARES.--
 
   (a) Failure to effectuate corporate action.--Within 60 days after the date
set for demanding payment and depositing certificates, if the business
corporation has not effectuated the proposed corporate action, it shall return
any certificates that have been deposited and release uncertificated shares
from any transfer restrictions imposed by reason of the demand for payment.
 
   (b) Renewal of notice to demand payment.--When uncertificated shares have
been released from transfer restrictions and deposited certificates have been
returned, the corporation may at any later time send a new notice conforming
to the requirements of section 1575 (relating to notice to demand payment),
with like effect.
 
   (c) Payment of fair value of shares.--Promptly after effectuation of the
proposed corporate action, or upon timely receipt of demand for payment if the
corporate action has already been effectuated, the corporation shall either
remit to dissenters who have made demand and (if their shares are
certificated) have deposited their certificates the amount that the
corporation estimates to be the fair value of the shares, or give written
notice that no remittance under this section will be made. The remittance or
notice shall be accompanied by:
 
      (1) The closing balance sheet and statement of income of the issuer of
  the shares held or owned by the dissenter for a fiscal year ending not more
  than 16 months before the date of remittance or notice together with the
  latest available interim financial statements.
 
      (2) A statement of the corporation's estimate of the fair value of the
  shares.
 
      (3) A notice of the right of the dissenter to demand payment or
  supplemental payment, as the case may be, accompanied by a copy of this
  subchapter.
 
   (d) Failure to make payment.--If the corporation does not remit the amount
of its estimate of the fair value of the shares as provided by subsection (c),
it shall return any certificates that have been deposited and release
uncertificated shares from any transfer restrictions imposed by reason of the
demand for payment. The corporation may make a notation on any such
certificate or on the records of the corporation relating to any such
uncertificated shares that such demand has been made. If shares with respect
to which notation has been so made shall be transferred, each new certificate
issued therefor or the records relating to any transferred uncertificated
shares shall bear a similar notation, together with the name of the original
dissenting holder or owner of such shares. A transferee of such shares shall
not acquire by such transfer any rights in the corporation other than those
that the original dissenter had after making demand for payment of their fair
value.
 
   (S) 1578. ESTIMATE BY DISSENTER OF FAIR VALUE OF SHARES.--
 
   (a) General rule.--If the business corporation gives notice of its estimate
of the fair value of the shares, without remitting such amount, or remits
payment of its estimate of the fair value of a dissenter's shares as
 
                                      C-4
<PAGE>
 
permitted by section 1577(c) (relating to payment of fair value of shares) and
the dissenter believes that the amount stated or remitted is less than the
fair value of his shares, he may send to the corporation his own estimate of
the fair value of the shares, which shall be deemed a demand for payment of
the amount or the deficiency.
 
   (b) Effect of failure to file estimate.--Where the dissenter does not file
his own estimate under subsection (a) within 30 days after the mailing by the
corporation of its remittance or notice, the dissenter shall be entitled to no
more than the amount stated in the notice or remitted to him by the
corporation.
 
   (S) 1579. VALUATION PROCEEDINGS GENERALLY.--
 
   (a) General rule.--Within 60 days after the latest of:
 
      (1) Effectuation of the proposed corporate action;
 
      (2) Timely receipt of any demands for payment under section 1575
  (relating to notice to demand payment); or
 
      (3) Timely receipt of any estimates pursuant to section 1578 (relating
  to estimate by dissenter of fair value of shares);
 
   If any demands for payment remain unsettled, the business corporation may
file in court an application for relief requesting that the fair value of the
shares be determined by the court.
 
   (b) Mandatory joinder of dissenters.--All dissenters, wherever residing,
whose demands have not been settled shall be made parties to the proceeding as
in an action against their shares. A copy of the application shall be served
on each such dissenter. If a dissenter is a nonresident, the copy may be
served on him in the manner provided or prescribed by or pursuant to 42
Pa.C.S. Ch. 53 (relating to bases of jurisdiction and interstate and
international procedure).
 
   (c) Jurisdiction of the court.--The jurisdiction of the court shall be
plenary and exclusive. The court may appoint an appraiser to receive evidence
and recommend a decision on the issue of fair value. The appraiser shall have
such power and authority as may be specified in the order of appointment or in
any amendment thereof.
 
   (d) Measure of recovery.--Each dissenter who is made a party shall be
entitled to recover the amount by which the fair value of his shares is found
to exceed the amount, if any, previously remitted, plus interest.
 
   (e) Effect of corporation's failure to file application.--If the
corporation fails to file an application as provided in subsection (a), any
dissenter who made a demand and who has not already settled his claim against
the corporation may do so in the name of the corporation at any time within 30
days after the expiration of the 60-day period. If a dissenter does not file
an application within the 30-day period, each dissenter entitled to file an
application shall be paid the corporation's estimate of the fair value of the
shares and no more, and may bring an action to recover any amount not
previously remitted.
 
   (S) 1580. COSTS AND EXPENSES OF VALUATION PROCEEDINGS.--
 
   (a) General rule.--The costs and expenses of any proceeding under section
1579 (relating to valuation proceedings generally), including the reasonable
compensation and expenses of the appraiser appointed by the court, shall be
determined by the court and assessed against the business corporation except
that any part of the costs and expenses may be apportioned and assessed as the
court deems appropriate against all or some of the dissenters who are parties
and whose action in demanding supplemental payment under section 1578
(relating to estimate by dissenter of fair value of shares) the court finds to
be dilatory, obdurate, arbitrary, vexatious or in bad faith.
 
                                      C-5
<PAGE>
 
   (b) Assessment of counsel fees and expert fees where lack of good faith
appears.--Fees and expenses of counsel and of experts for the respective
parties may be assessed as the court deems appropriate against the corporation
and in favor of any or all dissenters if the corporation failed to comply
substantially with the requirements of this subchapter and may be assessed
against either the corporation or a dissenter, in favor of any other party, if
the court finds that the party against whom the fees and expenses are assessed
acted in bad faith or in a dilatory, obdurate, arbitrary or vexatious manner
in respect to the rights provided by this subchapter.
 
   (c) Award of fees for benefits to other dissenters.--If the court finds
that the services of counsel for any dissenter were of substantial benefit to
other dissenters similarly situated and should not be assessed against the
corporation, it may award to those counsel reasonable fees to be paid out of
the amounts awarded to the dissenters who were benefited.
 
   (S) 1906. SPECIAL TREATMENT OF HOLDERS OF SHARES OF SAME CLASS OR SERIES.--
 
   (a) General rule.--Except as otherwise restricted in the articles, an
amendment or plan may contain a provision classifying the holders of shares of
a class or series into one or more separate groups by reference to any facts
or circumstances that are not manifestly unreasonable and providing mandatory
treatment for shares of the class or series held by particular shareholders or
groups of shareholders that differs materially from the treatment accorded
other shareholders or groups of shareholders holding shares of the same class
or series (including a provision modifying or rescinding rights previously
created under this section) if:
 
      (1) (i) such provision is specifically authorized by a majority of the
  votes cast by all shareholders entitled to vote on the amendment or plan,
  as well as by a majority of the votes cast by any class or series of shares
  any of the shares of which are so classified into groups, whether or not
  such class or series would otherwise be entitled to vote on the amendment
  or plan; and
 
       (ii) the provision voted on specifically enumerates the type and
  extent of the special treatment authorized; or
 
      (2) under all the facts and circumstances, a court of competent
  jurisdiction finds such special treatment is undertaken in good faith,
  after reasonable deliberation and is in the best interest of the
  corporation.
 
   (b) Statutory voting rights upon special treatment.--Except as provided in
subsection (c), if an amendment or plan contains a provision for special
treatment, each group of holders of any outstanding shares of a class or
series who are to receive the same special treatment under the amendment or
plan shall be entitled to vote as a special class in respect to the plan
regardless of any limitations stated in the articles or bylaws on the voting
rights of any class or series.
 
   (c) Dissenters rights upon special treatment.--If any amendment or plan
contains a provision for special treatment without requiring for the adoption
of the amendment or plan the statutory class vote required by subsection (b),
the holder of any outstanding shares the statutory class voting rights of
which are so denied, who objects to the amendment or plan and complies with
Subchapter D of Chapter 15 (relating to dissenters rights), shall be entitled
to the rights and remedies of dissenting shareholders provided in that
subchapter.
 
   (d) Exceptions.--This section shall not apply to:
 
      (1) The creation or issuance of securities, contracts, warrants or
  other instruments evidencing any shares, option rights, securities having
  conversion or option rights or obligations authorized by section 2513
  (relating to disparate treatment of certain persons).
 
      (2) A provision of an amendment or plan that offers to all holders of
  shares of a class or series the same option to elect certain treatment.
 
                                      C-6
<PAGE>
 
      (3) An amendment or plan that contains an express provision that this
  section shall not apply or that fails to contain an express provision that
  this section shall apply. The shareholders of a corporation that proposes
  an amendment or plan to which this section is not applicable by reason of
  this paragraph shall have the remedies contemplated by section 1105
  (relating to restriction on equitable relief).
 
   (S) 1930. DISSENTERS RIGHTS.--
 
   (a) General rule.--If any shareholder of a domestic business corporation
that is to be a party to a merger or consolidation pursuant to a plan of
merger or consolidation objects to the plan of merger or consolidation and
complies with the provisions of Subchapter D of Chapter 15 (relating to
dissenters rights), the shareholder shall be entitled to the rights and
remedies of dissenting shareholders therein provided, if any. See also section
1906(c) (relating to dissenters rights upon special treatment).
 
   (b) Plans adopted by directors only.--Except as otherwise provided pursuant
to section 1571(c) (relating to grant of optional dissenters rights),
Subchapter D of Chapter 15 shall not apply to any of the shares of a
corporation that is a party to a merger or consolidation pursuant to section
1924(b)(1)(i) (relating to adoption by board of directors).
 
   (c) Cross references.--See sections 1571(b) (relating to exceptions) and
1904 (relating to de facto transaction doctrine abolished).

The Board of Directors and Shareholders

We have audited the accompanying consolidated balance sheets of Integrated
Circuit Systems, Inc. and subsidiaries as of June 27, 1998 and June 28, 1997 and
the related consolidated statements of operations, shareholders' equity, and
cash flows for each of the years in the three-year period ended June 27, 1998.
In connection with our audits of the consolidated financial statements, we have
also audited the consolidated financial statement schedule, for each of the
years in the three-year period ended June 27, 1998. These consolidated financial
statements and the financial statement schedule are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements and financial statement schedule based on our
audits.

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

In our opinion, the consolidated financial statements referred to above present 
fairly, in all material respects, the financial position of Integrated Circuit 
Systems, Inc. and subsidiaries as of June 27, 1998 and June 28, 1997, and the 
results of their operations and their cash flows for each of the years in the 
three-year period ended June 27, 1998, in conformity with generally accepted 
accounting  principles.

Also in our opinion, the related financial statement schedule, when considered
in relation to the basic consolidated financial statements taken as a whole,
presents fairly, in all material respects, the information set forth therein.
