                                 JULY   , 1998
 
Dear Stockholders:
 
     You are cordially invited to attend a Special Meeting of stockholders of
GTI Corporation to be held at                on August   , 1998 at        local
time.
 
     At this meeting, you will be asked to vote on the acquisition, by means of
a merger, of GTI by a subsidiary of Technitrol, Inc. (the "Merger"). In the
Merger, you will be entitled to receive $3.10 in cash for each share of GTI
Common Stock that you own and $726.37 in cash for each share of GTI preferred
stock that you own.
 
     A merger agreement with Technitrol entities has been approved by your Board
of Directors. In deciding to approve the merger agreement, your Board of
Directors received the opinion of Cowen & Company, an investment banker, dated
May 26, 1998, to the effect that, based upon the assumptions made, matters
considered and the limitations on the review undertaken in connection therewith,
the consideration to be received by GTI Common Stockholders in the Merger, as of
such date, was fair to such stockholders (other than Technitrol and its
subsidiaries and affiliates) from a financial point of view. YOUR BOARD OF
DIRECTORS HAS CONCLUDED THAT THE PROPOSED MERGER IS IN THE BEST INTERESTS OF GTI
AND GTI'S STOCKHOLDERS AND, THEREFORE, YOUR BOARD OF DIRECTORS UNANIMOUSLY
RECOMMENDS THAT YOU VOTE FOR ADOPTION OF THE MERGER AGREEMENT.
 
     Telemetrix PLC, a United Kingdom corporation, which directly or indirectly
owns approximately 47.9% of the outstanding shares of GTI common stock and 100%
of the outstanding shares of GTI preferred stock, has entered into an agreement
with Technitrol pursuant to which Telemetrix has called a meeting of its
stockholders for July 17, 1998 to vote upon the disposition of Telemetrix's
shares of GTI capital stock, by means of the Merger. Telemetrix's board of
directors has recommended that Telemetrix stockholders vote in favor of such
disposition. If holders of a majority of the shares of Telemetrix present in
person or by proxy at that meeting vote in favor of such disposition, Telemetrix
has agreed to vote its GTI common and preferred stock for the Merger Agreement.
Trustees of certain trusts beneficially owning in excess of 47% of the
outstanding shares of Telemetrix voting capital stock have agreed with
Technitrol to cause such shares to be voted in favor of such disposition. GTI
will publicly announce the results of the Telemetrix stockholders meeting
promptly after it has taken place.
 
     The attached notice of 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. The merger is an important step for GTI and
its stockholders. THE MERGER CANNOT BE COMPLETED UNLESS GTI CORPORATION
STOCKHOLDERS ADOPT THE MERGER AGREEMENT.
 
                                          Sincerely,
 
                                          /s/ ALBERT J. HUGO-MARTINEZ

                        SPECIAL MEETING OF STOCKHOLDERS
                         TO BE HELD ON AUGUST    , 1998
 
To the stockholders of GTI Corporation:
 
     This notice is provided to inform you that a Special Meeting of
Stockholders of GTI Corporation ("GTI") will be held at                on August
  , 1998 at        local time (the "Meeting") for consideration of and action
upon the following matters:
 
          1. To consider and vote on a proposal (the "Proposal") to approve and
     adopt an Agreement and Plan of Merger, dated as of May 26, 1998 (the
     "Merger Agreement"), by and between GTI, Technitrol International, Inc.
     ("Parent") and Technitrol Acquisition, Inc. ("Acquisition," a wholly-owned
     subsidiary of Parent). Parent is a wholly-owned subsidiary of Technitrol,
     Inc., NYSE: TNL. Pursuant to the Merger Agreement, Acquisition will be
     merged into GTI (the "Merger"), with GTI continuing as the surviving
     corporation. If the Merger Agreement is adopted by the GTI stockholders,
     the other conditions to the Merger are satisfied or waived, and the Merger
     becomes effective, then each share of common stock of GTI issued and
     outstanding immediately prior to the effective time of the Merger (other
     than shares as to which statutory appraisal rights have been perfected)
     will be converted into the right to receive $3.10 in cash, without
     interest, and each share of preferred stock of GTI issued and outstanding
     immediately prior to the effective time of the Merger (other than shares as
     to which statutory appraisal rights have been perfected) will be converted
     into the right to receive $726.37 in cash, without interest. The complete
     terms of the Merger are contained in the Merger Agreement, which is
     included in the Proxy Statement as Appendix A.
 
          2. To transact such other business as may properly come before the
     Meeting and any postponement or adjournment thereof, and matters incident
     to the conduct of the Meeting.
 
     The Board of Directors has fixed the close of business on July   , 1998 as
the record date for the determination of stockholders of GTI entitled to notice
of, and to vote at, the Meeting and any postponement or adjournment thereof.
Stockholders may vote in person or by proxy. In the event that there are not
sufficient votes to approve the Proposal, GTI expects that the Meeting will be
postponed or adjourned in order to permit further solicitation of proxies by
GTI. The Proxy Statement and the accompanying proxy card was first sent to
stockholders on or about July   , 1998.
 
     Whether or not you plan to attend the Meeting in person, please mark, date
and sign your proxy, and mail it in the stamped envelope enclosed for your
convenience. In order to avoid the additional expense to GTI of further
solicitation, we ask your cooperation in mailing your proxy promptly. Returning
the proxy does not affect your right to vote in person on all matters brought
before the Meeting, but will help assure a quorum if you do not attend.
 
                                          BY ORDER OF THE BOARD OF DIRECTORS,
 
                                          /s/ BRUCE C. MYERS

                        SPECIAL MEETING OF STOCKHOLDERS
                               OF GTI CORPORATION
                                AUGUST    , 1998
                            ------------------------
 
                                    SUMMARY
 
     This summary highlights selected information from this document. You are
being asked to consider and vote on a proposal (the "Proposal") to approve and
adopt an Agreement and Plan of Merger, dated as of May 26, 1998 (the "Merger
Agreement"), by and between GTI Corporation, Technitrol International, Inc.
("Parent") and Technitrol Acquisition, Inc. ("Acquisition," a wholly-owned
subsidiary of Parent). Parent is a wholly-owned subsidiary of Technitrol, Inc.,
NYSE: TNL. As used herein, the term "Company" or "GTI" refers to GTI and, unless
specifically identified otherwise, all of its subsidiaries.
 
     Technitrol, Inc. has unconditionally guaranteed to GTI (the "Guaranty") the
prompt and complete payment and performance, when due, of all liabilities and
obligations of Parent to GTI under the Merger Agreement. Technitrol, Inc.,
Parent and Acquisition are herein collectively referred to as "Technitrol."
Pursuant to the Merger Agreement, Acquisition will be merged into GTI (the
"Merger"), with GTI continuing as the surviving corporation. Immediately after
the Merger, GTI will become a wholly-owned subsidiary of Technitrol.
 
     This summary may not contain all of the information that is important to
you. To understand the Merger fully and for a more complete description of the
complete terms of the Merger, you should read carefully this entire document and
the other documents referred to herein. See "Where You Can Find Additional
Information" at page 53 of this Proxy Statement. The complete terms of the
Merger are contained in the Merger Agreement, which is included in this Proxy
Statement as Appendix A.
 
THE MERGER CONSIDERATION
 
     If the Merger is completed, GTI stockholders who do not perfect their
statutory appraisal rights will receive $3.10 per share in cash for their GTI
Common Stock (the "Common Stock") and $726.37 per share in cash for their GTI
$35.00 Cumulative Convertible Preferred Stock (the "Preferred Stock") (which
amount equals the Preferred Stock to Common Stock conversion ratio of 234.314
multiplied by $3.10). The consideration to be received by holders of Common and
Preferred Stock is hereinafter referred to as the "Merger Consideration." The
total amount to be paid to all holders of Common and Preferred Stock (assuming
no stockholders perfect their statutory appraisal rights) will be approximately
$33.7 million. All outstanding options and warrants to purchase shares of Common
Stock will be cancelled at the effective time of the Merger (the "Effective
Time"). No holder of any such option or warrant will be entitled to receive any
amount on account of such cancellation, because the exercise price of each such
option and warrant is greater than $3.10 per share of Common Stock.
 
VOTING
 
     At the Meeting, the holders of Common and Preferred Stock will vote on the
Proposal to adopt the Merger Agreement. In order to be approved, a majority of
all the outstanding shares of Common Stock, and at least two-thirds of the
outstanding shares of Preferred Stock, voting as separate classes, must be voted
in favor of adopting the Merger Agreement. On the record date, there were
8,973,475 shares of Common Stock outstanding and entitled to vote which were
held by approximately                stockholders of record, and
<PAGE>   7
 
there were 8,110 shares of Preferred Stock outstanding and entitled to vote, all
of which were held by a wholly-owned subsidiary of Telemetrix, PLC, a United
Kingdom corporation ("Telemetrix").
 
     Telemetrix, which directly or indirectly owns approximately 47.9% of the
outstanding shares of Common Stock and 100% of the outstanding shares of
Preferred Stock, has entered into an agreement with Technitrol pursuant to which
Telemetrix has called a meeting of its stockholders for July 17, 1998 to vote
upon the disposition of Telemetrix's shares of Common Stock and Preferred Stock
by means of the Merger. Telemetrix's board of directors has recommended that
Telemetrix stockholders vote in favor of such disposition. If holders of a
majority of the shares of Telemetrix present in person or by proxy at that
meeting vote in favor of such disposition, Telemetrix has agreed to vote its
Common and Preferred Stock for the Merger Agreement. Trustees of certain trusts
beneficially owning in excess of 47% of the outstanding shares of Telemetrix
voting capital stock have agreed with Technitrol to cause such shares to be
voted in favor of such disposition. GTI will publicly announce the results of
the Telemetrix stockholders meeting promptly after it has taken place.
 
RECORD DATE
 
     The close of business on July   , 1998, is the record date for determining
those stockholders entitled to vote at the Meeting.
 
RECOMMENDATION OF GTI'S BOARD OF DIRECTORS (PAGE 21)
 
     GTI'S BOARD OF DIRECTORS HAS APPROVED THE MERGER AGREEMENT AND UNANIMOUSLY
RECOMMENDS THAT YOU VOTE TO ADOPT THE MERGER AGREEMENT. GTI'S BOARD OF DIRECTORS
BELIEVES THAT THE MERGER IS FAIR TO, AND IN THE BEST INTERESTS OF, GTI AND ITS
STOCKHOLDERS.
 
FACTORS CONSIDERED BY THE GTI BOARD OF DIRECTORS (PAGE 21)
 
     The Company's business is heavily dependent on the maturing market for LAN
products, which recently has experienced a downturn in the quantities of
products that the Company manufactures and sells. As a result of this downturn
and quality-control problems experienced by the Company in 1996, the market for
the Company's products contracted and has experienced significant competition
and price declines. As a result of these adverse trends, the Company experienced
significant operating losses in 1996 and 1997 and in the first quarter of 1998.
 
     On November 20, 1997, the GTI Board of Directors (the "Board") appointed a
Special Committee of two independent non-employee directors of GTI (the "Special
Committee") to examine strategic alternatives available to GTI, including a
possible sale of GTI. On January 15, 1998, the Board directed the Special
Committee to manage the process of considering strategic alternatives. On May
26, 1998, the Special Committee unanimously recommended the approval of the
Merger Agreement and the transactions contemplated thereby, including the
Merger.
 
     On May 26, 1998, the Company Board (with Mr. Venter not participating
because he was then in transit from Johannesburg, South Africa to London,
England to attend a meeting of the board of directors of Telemetrix) based upon,
among other things, the unanimous recommendation and approval of the Special
Committee, the fairness opinion received from the Special Committee's financial
advisor, Cowen & Company ("Cowen" or the "Financial Advisor"), and the Board's
independent review of the Merger Agreement and the other factors described
below, approved the Merger Agreement and the transactions contemplated thereby,
including the Merger, and it determined that the Merger is fair to, in the best
interests of, and produces the highest value reasonably obtainable by, the
stockholders of the Company and that it should recommend that the stockholders
of the Company adopt the Merger Agreement.

     Considerations of the Special Committee. In reaching its determination
referred to above, the Special Committee considered the following factors, each
of which, in the view of the Special Committee, supported such determination:
 
          1. The assessment of the Company's management, the Board and the
     Special Committee that the Company could not long sustain its continuing
     operating losses. It was the determination of the Special Committee that,
     in order for GTI to compete more effectively in its market and increase
     stockholder value, it would be necessary to become or combine with a
     larger, diversified and better capitalized enterprise. Further, it was the
     Special Committee's assessment that it would be difficult for the Company
     to achieve this substantial increase in size either by acquisition or
     through internal growth. Based in part on the advice of the Financial
     Advisor, the Special Committee concluded that GTI likely would encounter
     difficulties raising the additional capital necessary to produce value to
     the Company's stockholders at levels similar to $3.10 per share of Common
     Stock in the reasonably foreseeable future. This determination was also due
     in part to the fact that many of the Company's competitors are
     substantially larger, more diversified and better capitalized than the
     Company and, as a result, possess greater ability to effect acquisitions,
     to maintain necessary technology programs and to hire and retain employees.
     Accordingly, the Special Committee concluded that a sale of GTI at the
     current time is in the best interests of GTI and its stockholders and that
     the Company, acting independently, would be unlikely to produce value to
     its stockholders at a level similar to or greater than $3.10 per share of
     Common Stock in the reasonably foreseeable future.
 
          2. The fact that the Special Committee and, at its direction, the
     Financial Advisor, had conducted a wide-ranging process to identify and
     contact potential acquirers or others interested in a strategic
     relationship or transaction with GTI. The Special Committee, working with
     management and the Financial Advisor, developed a detailed strategy of
     approach, first to potential strategic acquirers who were not competitors,
     then to other potential strategic partners, next to potential financial
     acquirers and last to competitors. In all, 15 such parties were contacted.
     The Special Committee held numerous meetings and carefully monitored the
     progress of such discussions and directed management and the Financial
     Advisor with respect to such discussions. In addition, in February 1998,
     GTI publicly announced that it had retained the Financial Advisor to
     explore strategic alternatives, including the possible sale of GTI. Any
     potential acquirer or strategic partner who had not yet been contacted was
     thereby given notice that GTI was potentially for sale. Accordingly, the
     Special Committee believed that a full and fair market test had been done
     to establish the arm's-length market value of GTI. Since the May 27, 1998
     announcement of the Merger Agreement, neither GTI nor the Financial Advisor
     has received any bid or indication of interest of any kind from any party.
 
          3. The history of the negotiations between the Special Committee and
     Technitrol, including (i) the Special Committee's belief (and Technitrol's
     clearly stated position) that Technitrol would not further increase the
     Merger Consideration, and, accordingly, $3.10 per share of Common Stock and
     $726.37 per share of Preferred Stock was, in the opinion of the Special
     Committee, the highest price that could be obtained from Technitrol and
     (ii) the Special Committee's belief that further negotiations concerning
     price with Technitrol could cause Technitrol to terminate negotiations with
     respect to the Merger.
 
          4. That the Merger Consideration of $3.10 per share of Common Stock
     represents: (i) a premium of approximately 34% over the $2.3125 per share
     closing price on May 12, 1998, which was seven days prior to the May 19,
     1998 public announcement of the fact that the Company had signed a letter
     of intent with Technitrol for the merger of the Company at $3.10 per share
     of Common Stock in cash; (ii) a premium of approximately 15.3% over the
     $2.6875 per share closing price on May 20, 1998, which was seven days prior
     to the May 27, 1998 public announcement (the "Announcement") of the fact
     that the Company had entered into a definitive agreement for the merger of
     the Company at $3.10 per share of Common Stock in cash; (iii) a premium of
     approximately 3.3% over the $3.00 per share closing price on April 27,
     1998, which was 30 days prior to the Announcement; and (iv) a premium of
     approximately 19.4% over the average closing price for the one-month period
     preceding the Announcement. In addition, the shares of Common Stock have
     not traded in Nasdaq's National Market higher than $3.10 per share of
     Common Stock since April 21, 1998. The $3.10 price per share of Common
     Stock and the $726.37 price
                                        3
<PAGE>   9
 
     per share of Preferred Stock are payable in cash, thus eliminating any
     uncertainties in valuing the consideration to be received by the holders of
     Common Stock and Preferred Stock.
 
          5. The terms and conditions of the Merger Agreement, including two key
     provisions negotiated by the Special Committee. First, Technitrol cannot
     refuse to complete the Merger because of a decline in the financial
     performance of GTI after May 26, 1998, even if such decline has a Material
     Adverse Effect (as defined in the Merger Agreement) on GTI. Second, GTI's
     Board of Directors retains the right to consider unsolicited superior
     proposals received from third parties, supply non-public information to
     such third parties, and terminate the Merger Agreement under certain
     circumstances if an unsolicited superior offer is received, subject to
     fulfillment of certain financial obligations to Technitrol. See "Merger
     Agreement."
 
          6. The opinion of the Financial Advisor, addressed to the Special
     Committee and the Board, to the effect that, based upon the assumptions
     made, matters considered and the limitations on the review undertaken in
     connection therewith, the Merger Consideration of $3.10 per share of Common
     Stock, was, as of May 26, 1998, fair to holders of Common Stock (other than
     Technitrol and its subsidiaries and affiliates) from a financial point of
     view. See "Opinion of Cowen & Company" and the written opinion of the
     Financial Advisor attached as Appendix B.
 
          7. The possibility that the consideration the Company's stockholders
     might obtain in a future transaction was likely to be less advantageous
     than the Merger Consideration because of: the lower than expected Company
     earnings for the first fiscal quarter ended March 31, 1998, and the fiscal
     year ended December 31, 1997; the substantial uncertainty concerning
     whether the Company would be able to improve its performance in the
     nine-months ended September 30, 1998 or thereafter; the frequency with
     which the Company had, in the past, not met its internally projected
     results; and the uncertainty regarding the market for Local Area Network
     ("LAN") products, which account for in excess of 90% of the Company's
     revenues, and its effect on future Company earnings.
 
          8. The fact that Technitrol, Inc. was executing and delivering a
     guaranty of payment of the Merger Consideration by its subsidiary pursuant
     to the Merger Agreement, which increased the likelihood that the proposed
     acquisition would be consummated.
 
          9. While consummation of the Merger would result in the stockholders
     of the Company receiving a premium for their shares of Common Stock over
     the trading prices of such shares prior to the public announcement that the
     Company had signed a letter of intent for the sale of the Company at a
     price of $3.10 per share of Common Stock, consummation of the Merger would
     eliminate any opportunity for stockholders of the Company to participate in
     the potential future growth prospects, if any, of the Company. The Special
     Committee determined, however, that (a) the loss of opportunity is
     reflected in the price of $3.10 per share of Common Stock, and (b) there
     are continued substantial business risks associated with independent
     operation that could materially negatively affect the Company's ability to
     achieve the future operating results believed by the Special Committee to
     be necessary to achieve higher trading prices for the Common Stock.
 
     The foregoing discussion of the factors considered by the Special Committee
is not intended to be all-inclusive. In view of the variety of factors
considered in connection with its evaluation of the Merger, the Special
Committee did not find it practicable to and did not attempt to rank or assign
relative weights to the foregoing factors.
 
     Considerations of the Board. The members of the Board evaluated the factors
listed above in light of their knowledge of the business, financial condition
and prospects of the Company and based upon the advice of independent financial
and legal advisors. In addition, the Board determined that the Merger Agreement
was the result of a process that was fair to the stockholders of the Company
because, among other things, (a) a Special Committee was formed consisting of
members of the Board of Directors who are neither employees of the Company nor
affiliated with any substantial stockholder of the Company nor any of the
bidders, (b) the Special Committee conducted more than 20 meetings during the
period between the formation of the Special Committee and the execution and
delivery of the Merger Agreement, during which meetings the Special
 
                                        4
<PAGE>   10
 
Committee evaluated and analyzed the bids, determined the negotiating strategy
and reached informed conclusions based, in part, on the advice of its
independent financial and legal advisors, (c) the Board and the Special
Committee deliberated with respect both to the Merger and the alternative
strategies of remaining independent or seeking a joint venture to which the
Company would contribute substantially all of its assets and personnel, and (d)
the price of $3.10 per share of Common Stock and the other terms and conditions
of the Merger Agreement resulted from active arm's-length bargaining between the
Special Committee and Technitrol.
 
OPINION OF COWEN & COMPANY (PAGE 24)
 
     At the meetings of the Special Committee and the Board held on May 26,
1998, the Financial Advisor delivered to the Special Committee and the Board of
Directors its oral opinion, which opinion was subsequently confirmed in a
written opinion dated as of such date, to the effect that, based upon the
assumptions made, matters considered and the limitations on the review
undertaken in connection therewith, the Merger Consideration, as of May 26,
1998, was fair to holders of Common Stock (except Technitrol and its
subsidiaries and affiliates) from a financial point of view. The opinion of the
Financial Advisor is included in this Proxy Statement as Appendix B.
Stockholders of GTI are urged to read the opinion of the Financial Advisor in
its entirety.
 
INTERESTS OF GTI MANAGEMENT AND TELEMETRIX IN THE MERGER (PAGE 30)
 
     All members of the Board and executive officers of GTI own stock options
and/or Common Stock of GTI and, to that extent, their interest in the Merger is
the same as yours. However, some of the officers and directors of GTI have
interests in the Merger that are different from your interests as a stockholder.
Some of these interests are set forth below. The Board and the Special Committee
were aware of these interests and considered them in recommending and approving
the Merger.
 
     - Certain GTI officers, including Mr. Hugo-Martinez, who is also a
       director, will be entitled to receive change of control stay bonuses upon
       the effectiveness of the Merger. See "The Merger -- Interests of Certain
       Persons in the Merger."
 
     - The Merger Agreement provides that all rights to indemnification in favor
       of any present or former director or officer of GTI as provided in GTI's
       certificate of incorporation and bylaws or certain applicable
       indemnification agreements shall survive the Merger with respect to
       matters occurring at or prior to the Effective Time. Subject to certain
       limitations, the present GTI director and officer liability insurance
       policy coverage is to be maintained by the surviving corporation for six
       years. Technitrol, Inc. has guaranteed payment of the indemnity.
 
     - Certain of GTI's senior management may continue to be employed by
       Technitrol after the Merger. As of the date hereof, neither Mr.
       Hugo-Martinez nor any of the Company's other executive officers has, to
       the Company's knowledge, entered into any written or oral employment
       agreement with Technitrol.
 
     - The Merger Agreement requires that GTI repay its loan from Telemetrix
       (which directly or indirectly owns approximately 47.9% of the outstanding
       shares of Common Stock and 100% of the outstanding shares of Preferred
       Stock) immediately prior to the Effective Time as part of Technitrol's
       plan to replace all of the Company's financing facilities. This repayment
       will occur earlier than Telemetrix would otherwise have been repaid.
 
     - Consummation of the Merger will provide liquidity to Telemetrix for its
       substantial block of Common and Preferred Stock, which liquidity might
       not otherwise be available to Telemetrix.

APPRAISAL RIGHTS (PAGE 38)
 
     Any stockholder who does not wish to accept the Merger Consideration has
the right under the Delaware General Corporation Law (the "DGCL") to receive the
"fair value" of his or her shares of Common Stock or Preferred Stock as
determined by a Delaware court. This "appraisal right" is subject to a number of
restrictions and technical requirements. Generally, in order to perfect
appraisal rights:
 
     - you must not vote in favor of the Merger; and
 
     - you must make a written demand for appraisal before the vote on the
       Merger.
 
     Merely voting against the Merger will not protect your right of appraisal.
Appendix C to this Proxy Statement contains the applicable provisions of the
DGCL relating to appraisal rights. See "Appraisal Rights."
 
CONDITIONS TO THE MERGER (PAGE 34)
 
     The obligations of GTI and Technitrol to complete the Merger are subject to
a number of conditions. If these conditions are not satisfied or waived, the
Merger will not be completed. The most important of the mutual conditions are:
 
     - adoption of the Merger Agreement by holders of a majority of the
       outstanding shares of Common Stock and holders of at least two-thirds of
       the outstanding shares of Preferred Stock, voting as separate classes;
 
     - expiration or earlier termination of the waiting period under the
       Hart-Scott-Rodino Antitrust Improvements Act of 1976 ("HSR"); early
       termination was granted and became effective on June 19, 1998; and
 
     - no statute, rule, regulation, executive order, decree, ruling or
       injunction shall have been enacted, entered, promulgated or enforced by
       any United States court or United States governmental authority which
       prohibits, restrains, enjoins or restricts the consummation of the
       Merger.
 
     Several additional conditions exist that must be met to require Technitrol
to complete the Merger. The most important of these conditions are:
 
     - the representations of the Company contained in the Merger Agreement or
       in any other document delivered pursuant thereto shall be true and
       correct at and as of the Effective Time with the same effect as if made
       at and as of the Effective Time (except to the extent the representations
       specifically related to an earlier date, in which case such
       representations shall be true and correct as of such earlier date),
       provided that the representations of the Company and its subsidiaries
       which are not qualified by materiality or Material Adverse Effect (as
       defined in the Merger Agreement) shall be deemed for all purposes of the
       Merger Agreement to be true and correct if, in the aggregate the breach
       of all such representations, if any, do not have a Material Adverse
       Effect on the Company or the validity of the Merger;
 
     - each of the covenants and obligations of the Company to be performed at
       or before the Effective Time pursuant to the terms of the Merger
       Agreement shall have been duly performed in all material respects at or
       before the Effective Time;
 
     - the Company shall have obtained the consent or approval of each person
       whose consent or approval shall be required in connection with the
       transactions contemplated by the Merger Agreement under any loan or
       credit agreement, license, note, mortgage, indenture, lease or other
       agreement or instrument, except those for which failure to obtain such
       consents and approvals would not, individually or in the aggregate, have
       a Material Adverse Effect on the Company or the validity of the Merger;
 
     - receipt of an opinion of legal counsel to the Company as to certain
       matters set forth in Exhibit B to the Merger Agreement; and
 
                                        6
<PAGE>   12
 
     - GTI stockholders perfecting appraisal rights hold no more than 10% of the
       outstanding shares of Common Stock of GTI, assuming for purposes of such
       calculation the conversion to shares of Common Stock of all outstanding
       shares of Preferred Stock.
 
     Notwithstanding the above, the first three conditions precedent, above, to
Technitrol's obligation to complete the Merger will be deemed satisfied if such
conditions would have been satisfied but for the occurrence, between May 26,
1998 and the closing date of the Merger, of a reduction, compared to the first
quarter of fiscal year 1998, in the earnings before interest, taxes,
depreciation and amortization of the Company and its subsidiaries, on a
consolidated basis ("EBITDA") that has a Material Adverse Effect on the Company,
and the business and financial events resulting in such reduction in EBITDA were
not themselves initiated by one or more independent breaches by the Company of
the representations and warranties of the Company contained in the Merger
Agreement.
 
     Additional conditions exist that must be met to require GTI to complete the
Merger. The most important of these conditions are:
 
     - the representations of Parent and Acquisition contained in the Merger
       Agreement or in any other document delivered pursuant thereto shall be
       true and correct at and as of the Effective Time with the same effect as
       if made at and as of the Effective Time (except to the extent such
       representations specifically related to an earlier date, in which case
       such representations shall be true and correct as of such earlier date),
       provided that the representations of Parent and Acquisition which are not
       qualified by materiality or Material Adverse Effect shall be deemed for
       all purposes of this Agreement to be true and correct if, in the
       aggregate the breaches of all such representations, if any, do not have a
       Material Adverse Effect on Parent or Acquisition or the validity of the
       Merger;
 
     - each of the covenants and obligations of Parent and Acquisition to be
       performed at or before the Effective Time pursuant to the terms of this
       Agreement shall have been duly performed in all material respects at or
       before the Effective Time;
 
     - Parent shall have obtained the consent or approval of each person whose
       consent or approval shall be required in connection with the transactions
       contemplated by the Merger Agreement under any loan or credit agreement,
       note, mortgage, indenture, lease or other agreement or instrument, except
       those for which failure to obtain such consents and approvals would not,
       individually or in the aggregate, have a Material Adverse Effect on
       Parent or Acquisition or the validity of the Merger; and
 
     - receipt of an opinion of legal counsel to Parent as to the matters set
       forth in Exhibit A to the Merger Agreement.
 
TERMINATION OF THE MERGER AGREEMENT (PAGE 35)
 
     Either GTI or Technitrol may terminate the Merger Agreement if:
 
     - they mutually consent in writing to terminate the Merger Agreement;
 
     - a final order or similar action by a court of competent jurisdiction in
       the United States or other United States Governmental Entity (as defined
       in the Merger Agreement) restrains, enjoins or otherwise prohibits the
       Merger; or
 
     - the Merger has not been consummated by November 30, 1998, unless the
       terminating party has caused the failure to meet the closing conditions
       by failing to fulfill its obligations under the Merger Agreement.
 
     In addition, Technitrol may terminate the Merger Agreement if:
 
     - GTI breaches any of its representations or warranties in the Merger
       Agreement and the first or third condition precedent, above, to
       Technitrol's obligation to close the Merger is not capable of being
       satisfied by November 30, 1998.
 
                                        7
<PAGE>   13
 
     - GTI breaches a covenant in the Merger Agreement having a Material Adverse
       Effect on GTI or materially adversely affecting (or materially delaying)
       the consummation of the Merger, such that the second or third condition
       precedent, above, to Technitrol's obligation to close the Merger is not
       capable of being satisfied by November 30, 1998 and such breach has not
       been cured within twenty business days after notice thereof by
       Technitrol;
 
     - the Board has recommended to GTI's stockholders a Superior Proposal (as
       defined in the Merger Agreement) and GTI's stockholders have not adopted
       the Merger Agreement by November 30, 1998;
 
     - the Board has withheld, withdrawn, modified or changed its approval or
       recommendation of the Merger Agreement and GTI's stockholders have not
       adopted the Merger Agreement by November 30, 1998; or
 
     - GTI stockholders perfecting appraisal rights hold more than 10% of the
       outstanding shares of Common Stock of GTI, assuming for purposes of such
       calculation the conversion to shares of Common Stock of all outstanding
       shares of Preferred Stock.
 
     - the Board convenes a meeting of GTI stockholders to vote upon the Merger
       Agreement and the GTI stockholders fail to adopt the Merger Agreement.
 
     In addition, GTI may terminate the Merger Agreement if:
 
     - Parent or Acquisition breaches any of its representations or warranties
       in the Merger Agreement and the first or third condition precedent,
       above, to GTI's obligation to close the merger is not capable of being
       satisfied by November 30, 1998;
 
     - Parent or Acquisition breaches a covenant in the Merger Agreement
       materially adversely affecting (or materially delaying) the consummation
       of the Merger, such that the second or third condition precedent, above,
       to GTI's obligation to close the Merger is not capable of being satisfied
       by November 30, 1998 and such breach has not been cured within twenty
       business days after notice thereof by GTI; or
 
     - Section 4.4 of the Merger Agreement, relating to the receipt and
       evaluation by GTI of a Superior Proposal (as defined in the Merger
       Agreement), is satisfied.
 
TERMINATION FEES (PAGE 36)
 
     GTI will be required to pay Technitrol a termination fee equal to
Technitrol's actual documented out-of-pocket costs incurred, not to exceed
$750,000, if the Merger Agreement is terminated due to:
 
     - the Board's termination of the Merger Agreement pursuant to Section 4.4
       thereof, relating to the receipt and evaluation of a Superior Proposal;
 
     - the Board's recommendation of a Superior Proposal and the failure of the
       Company's stockholders to adopt the Merger Agreement, instead, by
       November 30, 1998;
 
     - the Board's withholding, withdrawal, modification or change of its
       approval or recommendation to GTI's stockholders of a vote for the
       adoption of the Merger Agreement, and the failure of the Company's
       stockholders to adopt the Merger Agreement, in any event, by November 30,
       1998; or
 
     - the Board's convening of a meeting of GTI stockholders to vote upon the
       Merger Agreement and the failure of the Company's stockholders to adopt
       the Merger Agreement.
 
     In addition, if the Merger is terminated as a result of one of the factors
enumerated in the preceding sentence and GTI consummates a transaction with
respect to a Third Party Acquisition Proposal (as defined in the Merger
Agreement) with a party other than Technitrol or enters into an option,
agreement or letter of intent with respect to a Third Party Acquisition Proposal
or other arrangement intended to transfer control of GTI or the stockholders of
GTI tender or grant an option on shares representing 50% or more of the voting
interest in GTI, within twelve months after termination (and, in the event the
Merger Agreement was terminated due to a failure of the Company's stockholders
to adopt the Merger Agreement at a meeting
                                        8
<PAGE>   14
 
convened by the Board to vote upon the Merger Agreement, a Third Party
Acquisition Proposal was outstanding at the time of such stockholders' meeting),
then GTI will pay to Technitrol an additional termination fee equal to $2
million less the amount paid pursuant to the immediately preceding sentence. The
termination fee is intended to be the only damages that Technitrol is entitled
to receive if the Merger Agreement is terminated for the first or second
grounds, above, on the basis of which Technitrol can terminate the Merger
Agreement.
 
FEDERAL INCOME TAX CONSEQUENCES (PAGE 37)
 
     A holder of Common Stock will be taxed for United States federal income tax
purposes on the receipt of the Merger Consideration to the extent that the
amount received exceeds the holder's tax basis in the Common Stock. Because the
tax consequences of the Merger can be complicated, especially in light of recent
changes to the United States federal tax laws governing capital gains, and
because state tax laws may apply as well, you should consult your tax advisor in
order to understand fully how the Merger will affect you. See "The
Merger -- Certain United States Federal Income Tax Consequences."
 
TIME, PLACE AND PURPOSE OF THE SPECIAL MEETING
 
     This proxy statement and the accompanying proxy card are solicited by the
Board. These proxies will be used at the Special Meeting of Stockholders (the
"Meeting") to be held at                local time, on August   , 1998 at
               , and at any and all adjournments thereof. The purpose of the
Meeting is to consider and vote on a proposal to adopt the Merger Agreement,
pursuant to which Acquisition will be merged into GTI with GTI continuing as the
Surviving Corporation. THE BOARD OF DIRECTORS OF GTI HAS APPROVED, AND
UNANIMOUSLY RECOMMENDS THAT GTI STOCKHOLDERS VOTE FOR ADOPTION OF, THE MERGER
AGREEMENT. See "The Merger -- Background of the Merger."
 
VOTING SECURITIES OF THE COMPANY
 
     Stockholders of record at the close of business on July   , 1998 (the
"Record Date") will be entitled to vote at the Meeting. On the Record Date,
there were outstanding 8,973,475 shares of Common Stock which were held by
approximately           stockholders of record, and 8,110 shares of Preferred
Stock, all of which were held by a wholly-owned subsidiary of Telemetrix.
 
     All shares represented by properly executed and unrevoked proxies will be
voted at the Meeting. The proxy accompanying this Proxy Statement may be revoked
at any time prior to voting by providing written notice to the Secretary of the
Company or by appearance at the Meeting and voting in person.
 
     At the Meeting, the holders of Common Stock and Preferred Stock will vote
on the Proposal to adopt the Merger Agreement. In order to be approved, holders
of a majority of the outstanding shares of Common Stock, and holders of at least
two-thirds of the outstanding shares of Preferred Stock, voting as separate
classes, must vote in favor of adopting the Merger Agreement in order for the
Proposal to be adopted. Votes withheld, abstentions and "broker non-votes" will
not be counted as votes cast and will not be voted.
 
     Telemetrix, which directly or indirectly owns approximately 47.9% of the
outstanding shares of Common Stock and 100% of the outstanding shares of
Preferred Stock, has entered into an agreement with Technitrol pursuant to which
Telemetrix has called a meeting of its stockholders for July 17, 1998 to vote
upon the disposition of Telemetrix's shares of Common Stock and Preferred Stock,
by means of the Merger. Telemetrix's board of directors has recommended that
Telemetrix stockholders vote in favor of such disposition. If holders of a
majority of the shares of Telemetrix present in person or by proxy at that
meeting vote in favor of such disposition, Telemetrix has agreed to vote its
Common and Preferred Stock for the Merger Agreement. Trustees of certain trusts
beneficially owning in excess of 47% of the outstanding shares of Telemetrix
voting capital stock have agreed with Technitrol to cause such shares to be
voted in favor of such disposition. GTI will publicly announce the results of
the Telemetrix stockholders meeting promptly after it has taken place.
 
                                        9
<PAGE>   15
 
     If the enclosed proxy is duly executed and received in time for the
Meeting, and if no contrary instructions are included on the proxy, it is the
intention of the persons named as proxies to vote the shares of Common Stock and
Preferred Stock represented thereby in favor of the Proposal to adopt the Merger
Agreement, and in the discretion of the persons named as proxies in connection
with any other business that may properly come before the Meeting or any
adjournment thereof.
 
     At this time, GTI knows of no other matters that may be presented for
stockholder action at the Meeting. However, if any matters, other than approval
of the Merger Agreement, should properly come before the Meeting, it is the
intention of the persons named in the enclosed proxy to vote such proxy in
accordance with their best judgment.
 
     In the event that there are not sufficient votes to approve the Proposal

                                   THE MERGER
 
PURPOSE, STRUCTURE AND EFFECT OF THE MERGER
 
     The purpose of the Merger is for Technitrol to acquire all of the
outstanding capital stock of GTI and to provide GTI stockholders (other than
those who perfect their statutory appraisal rights) with $3.10, in cash, for
each share of Common Stock that they hold and $726.37, in cash, for each share
of Preferred Stock that they hold. The Merger is structured as a cash merger of
Acquisition with and into GTI, with the result that GTI will be the surviving
corporation and a wholly-owned subsidiary of Parent. Under the Merger Agreement,
the certificate of incorporation, bylaws, officers and directors of Acquisition
immediately prior to the Effective Time shall be the certificate of
incorporation, bylaws, officers and directors of GTI on and immediately
following the Effective Time.
 
     If the Merger is consummated, the stockholders of GTI will no longer have
any equity interest in GTI, and therefore will not share in its future earnings
and growth, if any. Instead, each stockholder (other than stockholders who
perfect statutory appraisal rights) will receive, upon surrender of the
certificate or certificates, $3.10 per share of Common Stock, in cash, and
$726.37 per share of Preferred Stock, in cash. At such time, there will cease to
be any public market for the Common Stock and, after the Effective Time, the
Common Stock will be delisted from the Nasdaq National Market. Upon such event,
GTI will apply to the United States Securities and Exchange Commission (the
"Commission") for the deregistration of the Common Stock under the Securities
Exchange Act of 1934, as amended (the "Exchange Act").
 
BACKGROUND OF THE MERGER
 
     The Company's business is heavily dependent on the maturing market for LAN
products, which recently has experienced a downturn in the quantities of
products that the Company manufactures and sells. As a result of this downturn
and quality-control problems experienced by the Company in 1996, the market for
the Company's products contracted and has experienced significant competition
and price declines. As a result of these adverse trends, the Company experienced
significant operating losses in 1996 and 1997 and in the first quarter of 1998.
 
     At a meeting of the Board on November 20, 1997, the Board discussed at
length the Company's strategic situation and alternatives. It was the view of
the Company's management and the Board that the Company could not long sustain
its continuing operating losses. The Board also was of the view that the Company
would need to become or combine with a larger, diversified and better
capitalized enterprise in order to compete more effectively in its market and
increase stockholder value. Further, it was the Board's view that it would be
difficult for the Company to achieve this substantial increase in size either by
acquisition or through internal growth. This view was due in part to the
difficulty that GTI likely would encounter in trying to raise additional capital
in view of its continuing operating losses. This view was also due to the fact
that many of the Company's competitors are substantially larger, more
diversified and better capitalized than the Company and, as a result, possess
greater ability to effect acquisitions, to maintain necessary technology
programs and to hire and retain employees. In particular, the Board was of the
view that it might be in the best interests of the Company and its stockholders
to consider strategic alternatives, including the possible sale of GTI. GTI's
largest stockholder, Telemetrix, had expressed similar views. Accordingly, the
Board established a Special Committee made up of Messrs. Kenneth E. Maud and
Edmund B. Fitzgerald, who are not otherwise affiliated or associated with the
Company or Telemetrix, and authorized the Special Committee to engage an
investment banker and legal counsel to explore such strategic alternatives,
including the possible sale of GTI. Telemetrix advised the Board that Telemetrix
would be willing to consider disposal of its interest in GTI in connection with
a sale of GTI upon terms determined by the Special Committee to be fair to all
stockholders of the Company.
 
     The Special Committee elected Mr. Maud as its Chairman, considered several
investment banking firms and decided that the Special Committee should retain
its own legal counsel. These decisions were made at several meetings of the
Special Committee in November and December of 1997 and in the first two weeks of
January 1998. The Special Committee decided that the Financial Advisor should be
retained as investment banker and Gibson, Dunn & Crutcher LLP ("Legal Counsel")
should be retained as legal counsel to the
 
                                       12
<PAGE>   18
 
Special Committee. The Special Committee negotiated with the Financial Advisor
and Legal Counsel the terms of their respective engagements, especially with
respect to the Financial Advisor's fee structure and the defined circumstances
under which the Financial Advisor would be entitled to receive such fees.
 
     At a meeting of the Special Committee on January 14, 1998, representatives
of Legal Counsel made a lengthy presentation to the Special Committee concerning
the fiduciary duties of members of the Special Committee and of the Board. In
addition, the Financial Advisor discussed at length with the Special Committee
the strategic alternatives potentially available to the Company and a proposed
strategy for identifying and contacting potential strategic partners on a
confidential basis. The Financial Advisor had developed this proposed strategy
in consultation with management of the Company. The Special Committee
extensively discussed with the Financial Advisor this proposed strategy and the
Financial Advisor's view on the strategic alternatives potentially available to
the Company, including a possible sale of the Company. Following a thorough
discussion, the Special Committee decided to recommend to the Board that the
Financial Advisor promptly finalize a list of potential strategic partners,
ranking them in three tiers based on the perceived likelihood of each party in a
particular tier submitting a favorable proposal to the Company.
 
     After excluding representatives of the Company's management, the Special
Committee was advised that it was not uncommon for key managers of a corporation
to be provided with change of control packages when the corporation was
considering strategic alternatives. Following extensive discussion, the Special
Committee determined that it should recommend that the Board approve such a
package, reflecting concepts that the Special Committee had discussed with its
advisors, because the Special Committee believed that it would be in the best
interests of the Company and its stockholders for the Company to offer a change
of control stay bonus and severance package to key managers of the Company in
order to retain their services through the period of examining strategic
alternatives and to provide appropriate incentives to the management in
achieving the Company's strategic goals.
 
     On January 15, 1998, the Board met. Representatives of Legal Counsel made a
lengthy presentation to the Board concerning the fiduciary duties of the members
of the Board and discussing the appropriate steps to be taken by members of the
Board during the process of considering strategic alternatives. In addition,
representatives of the Financial Advisor discussed at length with the Board the
strategic alternatives potentially available to the Company and a proposed
strategy, developed by the Financial Advisor in consultation with management,
for exploring such strategic alternatives. The Board discussed with the
Financial Advisor and management the potential strategic partners that had been
identified thusfar. After the Company's management was excused, the Board
discussed and was advised concerning the advisability of entering into change of
control stay bonus and severance agreements with key managers of the Company
along the lines discussed by the Special Committee. The Board, Legal Counsel and
the Financial Advisor discussed the appropriate process to be followed by the
Board and the Special Committee in order to best serve the interests of the
Company and its stockholders, with Legal Counsel discussing the issue in the
context of the DGCL and applicable securities laws. With the representatives of
Legal Counsel and the Financial Advisor excused, the Board discussed with the
Special Committee the advisability of retaining Legal Counsel and the Financial
Advisor to advise and assist the Special Committee in exploring strategic
alternatives available to GTI, including a possible sale of GTI. After
management of the Company and the representatives of the Financial Advisor and
Legal Counsel had been readmitted to the meeting, the Board adopted resolutions
approving the recommendation of the Special Committee to retain Cowen & Company
as investment bankers and Gibson, Dunn & Crutcher LLP as legal counsel to the
Special Committee. Further, the Board directed the Financial Advisor to refine
the proposed strategy for approaching potential strategic partners, based on the
discussions with respect to the potential strategic partners. In addition, the
Board decided that the Special Committee should manage the process of
considering strategic alternatives, in consultation with management, the
Financial Advisor and Legal Counsel. The Board approved the adoption of a change
of control stay bonus and severance package for key managers, reflecting the
concepts discussed by the Special Committee. The Board, with Mr. Hugo-Martinez
abstaining from such Board vote, directed the Special Committee, in consultation
with Legal Counsel, to negotiate change of control agreements with the key
managers. See "The Merger -- Interests of Certain Persons in the Merger."

     A meeting of the Special Committee was held on January 20, 1998. The
representatives of the Financial Advisor updated and reviewed the list of
potential strategic partners and their placement within the tiered structure
proposed. The Special Committee discussed in detail with management and
representatives of the Financial Advisor each of the possible strategic partners
in the upper tiers of the strategic partner list. The Special Committee
discussed with management and the Financial Advisor the prospect that each of
these potential strategic partners would make a proposal for a strategic
relationship with the Company, including a possible purchase of the Company, and
discussed the timing and method of the approaches to be used for each. In
addition, the Special Committee discussed the form of confidentiality agreement
that each potential strategic partner would be required to sign, the materials
to be circulated to potential strategic partners, the proposed engagement letter
with the Financial Advisor, a proposed letter agreement with Telemetrix
concerning the expressed willingness of Telemetrix to pay certain of the costs
incurred by the Company in case Telemetrix decided to sell its Common Stock and
Preferred Stock in a transaction that did not involve the sale of GTI as a
whole. Further, the Special Committee discussed with key managers of the Company
the proposed change of control agreements and the preparation of a data room at
the Company for use by potential strategic partners.
 
     Following the January 20, 1998 meeting of the Special Committee, the
Financial Advisor and GTI management began contacting select potential strategic
partners on a confidential basis in accordance with the directions of the
Special Committee. On January 29, 1998 the Special Committee met to discuss with
management and the Financial Advisor the contacts that had occurred with
potential strategic partners since the January 20, 1998 meeting of the Special
Committee. The Special Committee discussed with management and the Financial
Advisor the likelihood that each of the potential strategic partners contacted
would submit a proposal. The Special Committee also discussed with management
and the Financial Advisor the best approach to be used with each such potential
strategic partner. Following the January 29, 1998 meeting of the Special
Committee, the Financial Advisor and management continued the process of
contacting potential strategic partners and discussing strategic alternatives
with them.
 
     A meeting of the Special Committee was held on February 5, 1998. The
Special Committee discussed the appropriateness of making a public disclosure
concerning the fact that the Company had retained the Financial Advisor to
explore strategic alternatives. The Special Committee sought the advice of Legal
Counsel, the Financial Advisor and management concerning the appropriateness and
effect of such a disclosure at that time. The Special Committee also discussed
the best means of informing employees that strategic alternatives were being
considered. The Special Committee directed that a press release be issued after
the close of business on Friday, February 6, 1998, stating that the Company had
retained the Financial Advisor to explore strategic alternatives, including a
possible sale of the Company. In addition, the Special Committee discussed with
management and the Financial Advisor the results of discussions that had
occurred with potential strategic partners as well as plans for future contacts
with potential strategic partners. The Special Committee discussed the process
of encouraging potential strategic partners to give an indication of their
interest and in expediting their due diligence processes.
 
     Between February 5, 1998 and March 2, 1998, the Financial Advisor and
management conducted discussions with numerous potential strategic partners. Of
the parties contacted, six eventually executed confidentiality agreements and
received information from the Company.
 
     The Special Committee met on February 19, 1998 to discuss with management
and representatives of the Financial Advisor the progress to date with each of
the potential strategic partners. The Special Committee discussed the best means
of continuing ongoing discussions with each of the potential strategic partners
and the schedule for such potential strategic partners to give an indication of
interest. The Special Committee also discussed the need to expedite the process
to mitigate disruption to GTI's business. The Special Committee and management
also considered the sensitivity around soliciting interest from competitors.
 
     The Special Committee met on March 2, 1998 to discuss with management and
the Financial Advisor the progress to date with each of the potential strategic
partners. The Special Committee discussed the best means of continuing ongoing
discussions with each of the potential strategic partners and of accelerating
the schedule for obtaining indications of interest from such potential strategic
partners. The Special Committee
 
                                       14
<PAGE>   20
 
determined to set the last day of March as a deadline for receiving indications
of interests from potential strategic partners. On March 19, 1998, the Special
Committee directed that a letter be dispatched to each potential strategic
partner advising it of such deadline.
 
     The Board also met on March 19, 1998. The Financial Advisor discussed with
the Board the nine potential strategic partners with whom it was engaged in
discussions, of which six eventually executed confidentiality agreements with
the Company. Management discussed with the Board its preliminary view that the
revised projections for the first quarter of 1998 that had been presented to the
Board on January 14, 1998 appeared to be likely to be missed by a substantial
amount. The Board discussed at length with management its new projections, based
on current rates of sales. The Board directed the Financial Advisor to notify
the potential strategic partners that had executed confidentiality agreements of
the expected variance of first quarter results from the projections that had
been discussed by the Financial Advisor or GTI with such potential strategic
partners. The Board also concurred with the Special Committee's decision to
inform all interested parties that non-binding indications of interest were due
no later than March 31, 1998.
 
     The Special Committee met on March 31, 1998. The Financial Advisor reported
that it had received two written indications of interest; a third potential
bidder was still evaluating a possible strategic partnership with the Company
and had sought an extension of the deadline for submitting an indication of
interest to April 10, 1998; a fourth potential strategic partner had stated to
the Financial Advisor that it would need third-party financing before submitting
a written indication of interest and was unable to do so at the present time;
and Technitrol had stated to the Financial Advisor that it would be submitting
an indication of interest within the next several days. The Financial Advisor
and Mr. Hugo-Martinez also reported that one of the parties that had submitted a
written indication of interest had apparently withdrawn its indication of
interest. The Special Committee directed Mr. Hugo-Martinez to contact such party
to determine whether such party was indeed withdrawing from the process. The
Financial Advisor next discussed with the Special Committee the specific
transaction structures that were being considered by the parties expressing an
interest in the Company. Mr. Hugo-Martinez discussed with the Special Committee
the current cash status of the Company and described to the Special Committee
his contacts with certain of the Company's major customers, who were expressing
an unwillingness to issue purchase orders to the Company or to design into their
forthcoming products the Company's components until such customers knew who
would ultimately be the strategic partner of the Company. Following extensive
discussion, the Special Committee directed the Financial Advisor to contact
Technitrol to encourage Technitrol speedily to submit an indication of interest.
In addition, the Special Committee directed the Financial Advisor to contact the
potential strategic partner that had requested an extension through April 10,
1998 to submit a bid and to state that the Special Committee was prepared to
give such party the additional ten days to submit a written indication of
interest. The Special Committee determined that it was prepared to extend the
March 31, 1998 deadline for the submission of written indications of interest
because the Special Committee believed that it would be in the best interests of
the Company and its stockholders to solicit and obtain additional written
indications of interest. The Special Committee discussed in detail with
management, and the representatives of the Financial Advisor and Legal Counsel,
the one written indication of interest that had not been withdrawn. The
Financial Advisor presented information concerning the party that had submitted
such written indication of interest and Technitrol. The Special Committee
directed the Financial Advisor and Legal Counsel to contact such party to obtain
further information concerning the specifics of such party's interest. Because
such party had proposed a stock-for-stock merger, the Financial Advisor was
directed to prepare additional information for the Special Committee concerning
the value and the marketability of the securities to be received in the proposed
stock-for-stock merger with such party.
 
     On March 31, 1998, pursuant to the direction of the Special Committee,
representatives of the Financial Advisor and Legal Counsel conducted a lengthy
discussion with the party that had submitted a written indication of interest in
a stock-for-stock merger with GTI (the "Stock Merger Bidder"). Such party stated
that its proposed stock-for-stock merger would provide only non-voting stock to
GTI stockholders and would not include any cash component. Such party stated
that, although its charter did not presently authorize a class of non-voting
common stock, it proposed to seek an amendment of its charter to so provide.
Such party also stated its unwillingness to modify its proposal to include
voting stock or cash.

     On April 2, 1998 the Special Committee met. The Financial Advisor reported
to the Special Committee that, although the Financial Advisor had not yet
received a written indication of interest from Technitrol, Technitrol had stated
that it expected to provide such a written indication of interest later that
day. The Financial Advisor next described to the Special Committee the March 31,
1998 discussions that the Financial Advisor and Legal Counsel had conducted with
the Stock Merger Bidder. In addition, the Financial Advisor stated to the
Special Committee that the Financial Advisor had received a subsequent call from
the Stock Merger Bidder stating that it was re-evaluating its proposed merger
consideration value in light of the decline in the Company's anticipated first
quarter financial results, as reported in the Company's Form 10-K. Mr.
Hugo-Martinez advised the Special Committee that the party that had submitted a
written indication of interest but had subsequently indicated that it was
withdrawing from the process, had confirmed to him that it was indeed so
withdrawing. The Financial Advisor reported to the Special Committee that the
party that had requested until April 10, 1998 to submit a written indication of
interest was, as of April 2, 1998, not yet prepared to submit a written
indication of interest. Mr. Hugo-Martinez stated to the Special Committee that
the Company's business was continuing to decline, and that the entire LAN market
was showing no signs of recovery. He again stated that certain of the Company's
major customers were unwilling to commit to orders and design activity until
they know who would be the Company's strategic partner. The Special Committee
directed the Financial Advisor to contact Technitrol and the party that had
requested until April 10, 1998 to submit an indication of interest, to encourage
them to submit their indications of interest as soon as possible.
 
     The Special Committee met on April 6, 1998. The Financial Advisor reported
that it had received an indication of interest from Technitrol, contemplating an
acquisition of GTI by Technitrol at a price of $4.00 in cash per share of Common
Stock. The Financial Advisor further stated that, although Technitrol had
indicated that it would need 45 to 60 days of due diligence before commencing
definitive discussions with the Company, the Financial Advisor had told
Technitrol that a period that long would be unattractive to the Board and the
Special Committee. The Financial Advisor also reported that the Stock Merger
Bidder, which had stated to the Financial Advisor that it was in the process of
revising downwards its indication of interest, expected to send a revised offer
within the next several days. In addition, the Financial Advisor related that
the bidder that had requested until April 10, 1998 to submit a bid had
reiterated that it did not expect to be able to submit any indication of
interest until April 10, 1998, at the earliest. The Special Committee engaged in
an extensive discussion of the timing of possible transactions with the
potential strategic partners, as well as the best approach to deal with each of
them. The Special Committee directed the Financial Advisor to contact Technitrol
and the Stock Merger Bidder and to state to such parties that they were being
given one week to clarify their bids, diligence periods and the other key terms
of their proposals. The Special Committee directed Legal Counsel to dispatch
draft definitive merger agreements to Technitrol and the Stock Merger Bidder.
 
     The Special Committee met on April 8, 1998. The Special Committee discussed
with management, the Financial Advisor and Legal Counsel the bids of Technitrol,
the Stock Merger Bidder, and the status of the party that requested until April
10, 1998 to submit an indication of interest. Management and the Financial
Advisor reported that such bidder had stated that it was unlikely to submit a
bid by April 10, 1998. The Special Committee discussed in detail the requirement
by Technitrol that its $4.00 per share of Common Stock cash proposal be
conditional on Technitrol finding synergies through its due diligence process
before confirming such price and that it be granted exclusivity in the bidding
process for a period of 60 days. The Special Committee extensively discussed the
timing of the several possible transactions and the need to proceed
expeditiously, given the continuing deterioration of the Company's operating
results.
 
     On April 9, 1998, the Board met. The Special Committee summarized its
activities to date, reviewing in detail the meetings of the Special Committee
and the process conducted. In addition, the Special Committee summarized the
indications of interest received to date and recommended waiting no later than
April 13, 1998 to receive an indication of interest from the party that had
requested until April 10, 1998. The Board engaged in an extensive discussion of
the indications of interest received to date. In addition, the Board discussed
at considerable length the other strategic alternatives available to the
Company. The Financial Advisor advised the Board that it believed that the
probability of finding a financial buyer for the Company had always been small,
and none of the potential financial buyers with whom the Financial Advisor had
discussions had submitted an indication of interest to the Financial Advisor.
The Board further discussed the current state of
 
                                       16
<PAGE>   22
 
the Company's business and the necessity of proceeding expeditiously. The Board
adopted the recommendation of the Special Committee that Mr. Fitzgerald and a
representative of Legal Counsel meet with representatives of Technitrol and the
Stock Merger Bidder to clarify and make more firm their respective proposals.
 
     On April 16, 1998, Mr. Fitzgerald and a representative of Legal Counsel met
with representatives of Technitrol. Mr. Fitzgerald expressed the Special
Committee's concern that the $4.00 per share of Common Stock cash proposal
received from Technitrol was not firm, that the combined due diligence and
definitive negotiation periods of 60 days were too long and that Technitrol's
requirement for a 60-day exclusivity period was problematic in light of the fact
that its proposal was not firm. Following extensive discussion, Technitrol
agreed that if it were granted exclusivity for 45 days, it would perform all of
its economic, synergistic and other due diligence tasks during this time while
concurrently negotiating the definitive merger agreement. It also committed
that, if at any time prior to the expiration of such 45 day period, it became
apparent to Technitrol that it would be unable to confirm the $4.00 per share of
Common Stock cash price, Technitrol would advise the Company immediately.
Technitrol further agreed that the definitive merger agreement would not
condition Technitrol's obligation to consummate the Merger on there not having
been a material adverse change in the financial condition of the Company between
the date of signing of the definitive merger agreement and the consummation of
the transaction.
 
     On April 16, 1998, Mr. Fitzgerald and a representative of Legal Counsel
also met with representatives of the Stock Merger Bidder. The representatives of
the Stock Merger Bidder stated that its indicated merger consideration value of
$4.75 per share of Common Stock in non-voting common stock of the Stock Merger
Bidder was not firm, and would not be firm until it, too, had completed its
economic, synergistic and other due diligence process, which it expected would
take six weeks to complete. The representatives of the Stock Merger Bidder also
stated that under no circumstances would it be prepared to pay in the aggregate,
in merger consideration and total transaction costs, a price in excess of the
Company's 1998 estimated sales. Based on then current estimates of the Company,
such a limit would have translated, on April 16, 1998, into approximately $4.00
per share of Common Stock in non-voting stock of the Stock Merger Bidder. In
addition, the representative of the Stock Merger Bidder stated that such value
of merger consideration would not be guaranteed if the market price of the
non-voting stock on the closing date of the merger were less than the market
price of the non-voting stock on the date of executing the definitive merger
agreement by more than 10% or 15%. Mr. Fitzgerald noted that a substantial
amount of risk would be created for GTI stockholders by this sort of "collar"
around the price of a security which did not then exist and therefore would have
a very limited trading history on the date of the definitive merger agreement.
The Stock Merger Bidder stated that it would not negotiate a definitive merger
agreement with the Company until after the authorization of the new non-voting
stock at a stockholders meeting tentatively scheduled for mid-June, 1998.
Representatives of the Stock Merger Bidder further stated that the definitive
merger agreement would need to condition its obligation to consummate the merger
on there not having been a material adverse change in the financial condition of
the Company between the signing of the definitive merger agreement and the
consummation of the transaction. In addition, because the transaction would
require the separate approval of the stockholders of the Stock Merger Bidder,
its representatives acknowledged that, even if a contrary provision were
included in the definitive merger agreement, it would not prevent the
stockholders of the Stock Merger Bidder from voting against the transaction in
the event of a material adverse change in the financial conditions of the
Company subsequent to the signing of the definitive merger agreement.
 
     The Special Committee met on April 16, 1998 to discuss Mr. Fitzgerald's
meetings that day with Technitrol and the Stock Merger Bidder. Mr. Fitzgerald
described in detail these discussions, with a particular focus on the merger
consideration offered by each potential strategic partner and the timing and
conditions of closing that had been addressed with the two potential strategic
partners. The Special Committee discussed with the Financial Advisor the issues
that arose in evaluating and comparing the two proposals.
 
     The Board met on April 17, 1998. Mr. Fitzgerald reported to the Board at
considerable length concerning his discussions the previous day with the
representatives of Technitrol and the Stock Merger Bidder. The Board sought the
advice of the Financial Advisor and Legal Counsel concerning these two
proposals. Following lengthy discussions with the Financial Advisor and Legal
Counsel, the Board accepted the
                                       17
<PAGE>   23
 
recommendation of the Special Committee that the Company agree to grant
Technitrol a 45 day exclusivity period during which Technitrol would complete
its due diligence and a definitive merger agreement would be negotiated. The
Board took special note of the fact that, although the indicated value of the
merger consideration proposed by the Stock Merger Bidder was nominally in excess
of the merger consideration proposed by Technitrol, the Stock Merger Bidder had
stated that the value of its merger consideration, together with all of its
transaction costs, would in no event exceed the estimated 1998 revenues of the
Company, which, in light of the Company's then current estimates, would
translate into an aggregate merger consideration of approximately the same level
as that of Technitrol's proposal. If there were further deterioration in sales
(which has, in fact, occurred), the Stock Merger Bidder's proposed merger
consideration would fall commensurately. In addition, the Board took note of the
fact that the Stock Merger Bidder's proposal contemplated that merger
consideration be paid in a class of securities that did not presently exist and
was of uncertain value and liquidity. In light of this uncertainty, the Board
was troubled that the Stock Merger Bidder had proposed that a rather tight
"collar" would be placed around the target market price of the Stock Merger
Bidder's proposed non-voting common stock, the effect of which would be to
permit the Stock Merger Bidder to condition its obligation to consummate the
merger on there not being a decline, below the collar, in the traded market
price of its then-recently-created non-voting common stock. The trading volume
of the existing voting capital stock of the Stock Merger Bidder was, the
Financial Advisor reported, relatively low compared to the amount of stock
contemplated to be issued in the Stock Merger Bidder's transaction. The Board
noted Technitrol's strong cash position and substantial unused lines of credit
as well as its history of completing acquisitions. The Board further took note
that the Technitrol bid proposed a schedule that would lead to the signing of a
definitive merger agreement substantially sooner than that proposed by the Stock
Merger Bidder; that Technitrol did not require approval of its stockholders in
order to consummate the Merger; and that Technitrol had agreed that the
definitive merger agreement would not permit Technitrol to condition its
obligation to consummate the Merger on there not having been a material adverse
change in the financial condition of the Company after the signing of a
definitive agreement and prior to the consummation of the transaction. By
contrast, the Stock Merger Bidder was unwilling to agree to such a provision. In
any case, the Stock Merger Bidder required a stockholders meeting to approve the
merger prior to the closing date and therefore could not guarantee that a
material adverse change in the financial condition of the Company would not
prevent consummation of the merger. These factors were particularly important to
the Board in light of the continuing decline in the Company's operating results.
The Board concluded that the Technitrol proposal was superior and directed
management to make available on a highly expedited basis all appropriate
information concerning the Company requested by Technitrol. The Board further
directed the Special Committee to oversee Technitrol's due diligence process and
to negotiate the Merger Agreement on behalf of the Company, in consultation with
management, Legal Counsel and the Financial Advisor.
 
     Beginning on April 20, 1998, extensive information was made available to
Technitrol to permit it to conduct its due diligence on an expedited basis. On
April 27, 1998, representatives of Technitrol met, at Technitrol's request, with
Mr. Fitzgerald and a representative of Legal Counsel. At this meeting, the
representatives of Technitrol stated that the business of the Company was in
worse condition than they previously had understood and that, accordingly,
Technitrol was informing the Company, pursuant to Technitrol's statement of
April 16, 1998, that it would be unable to confirm a price of $4.00 per share of
Common Stock in cash. The representatives of Technitrol further stated that they
expected to be able to complete their due diligence within two weeks from April
27, 1998, and to confirm an offer price at that time, which was earlier than
Technitrol originally had thought feasible. From April 27, 1998 through May 10,
1998, Technitrol continued its due diligence process. Management promptly
responded to numerous oral and written requests for information from Technitrol.
 
     On May 11, 1998, representatives of Technitrol met with management, Mr.
Maud and a representative of Legal Counsel to discuss Technitrol's analysis of
possible merger consideration and the basis of such analysis in terms of
synergies and revenue effects anticipated to occur during the three years
following the effectiveness of the Merger. Management and Mr. Maud engaged in
lengthy discussions with the representatives of Technitrol concerning their
assumptions and analysis. Following this meeting, the Special Committee convened
to discuss the meeting with the representatives of Technitrol and to determine
the appropriate strategy for the Company in its negotiations with Technitrol.
                                       18
<PAGE>   24
 
     On May 13, 1998, the Special Committee met. Mr. Fitzgerald reported that a
senior representative of Technitrol had called and stated that, based on its due
diligence and financial analysis, Technitrol was obliged to reduce its offer to
$3.00 per share of Common Stock in cash. The Special Committee discussed with
the Financial Advisor the price now offered by Technitrol, in light of the
proposed terms of the Merger. The Special Committee discussed with the Financial
Advisor and Legal Counsel the alternative of commencing discussions with the
Stock Merger Bidder. The Special Committee decided to continue instead with
negotiations with Technitrol for the following reasons. First, each of the
problems and uncertainties with the Stock Merger Bidder's proposal that the
Board had discussed on April 17, 1998, continued to be true and had been
exacerbated by continuing declines in the Company's sales, which would, as
stated by the Stock Merger Bidder on April 16, 1998, reduce its offer
commensurately. Second, the Special Committee considered that Technitrol had
invested considerable expense and time in its strategic, synergistic and other
due diligence with respect to GTI and would be likely to cease to continue its
interest in GTI if GTI were to attempt to delay further discussions with
Technitrol for the six-week period that the Stock Merger Bidder had stated it
required before providing a firm offer. Third, in light of the decline in the
operating results of the Company, the Special Committee believed it to be
imperative to enter into a definitive merger agreement as soon as practicable,
with as few obstacles to closing as practicable. The Special Committee
determined that Mr. Fitzgerald should commence negotiations with representatives
of Technitrol in order to attempt to increase the merger price offered by
Technitrol and to reach agreement on certain outstanding issues that would need
to be included in the Merger Agreement, including the ability of the Board to
consider and accept an unsolicited superior offer, if one should be forthcoming
from another party.
 
     On May 15, 1998, the Special Committee met. Mr. Fitzgerald reported to the
Special Committee that, as a result of his negotiations with representatives of
Technitrol, Technitrol had agreed to increase the merger price to $3.10 per
share of Common Stock in cash, subject to negotiation of the Merger Agreement.
The Special Committee discussed with the Financial Advisor its views (and, in
particular, the assumptions underlying such views) concerning the $3.10 per
share of Common Stock cash offer, in light of the proposed terms of the Merger
Agreement. The Special Committee also discussed with the Financial Advisor
Technitrol's offer in light of the extensive process that the Special Committee
had conducted, including the contacting of numerous potential strategic buyers.
The Special Committee directed management and Legal Counsel to work with the
Special Committee to negotiate the Merger Agreement on an expedited basis.
 
     Between May 15, 1998 and May 18, 1998, at the request of Technitrol, the
Special Committee negotiated with Technitrol the terms of a non-binding letter
of intent providing for the merger of GTI with a subsidiary of Technitrol at a
price of $3.10 in cash per share of Common Stock and $726.37 in cash per share
of Preferred Stock. At the request of Technitrol, Telemetrix's board of
directors and a committee thereof adopted resolutions providing that, if the
consideration and the terms of the Merger Agreement to be negotiated
substantially reflected the consideration and terms of the proposed bid of
Technitrol set out in the letter of intent (and such other terms as were
acceptable to the Telemetrix board of directors or such committee), then
Telemetrix's board of directors would: duly call, give notice of and convene a
meeting of its stockholders to approve of the disposition, by the Merger, of all
of Telemetrix's shares of Common Stock and Preferred Stock; recommend a vote for
such approval, subject to the directors' fiduciary duties; and cause such shares
of Common Stock and Preferred Stock to be voted to adopt the Merger Agreement,
if the Telemetrix stockholders approved such disposition at such stockholders
meeting. At the request of Technitrol, trustees of certain trusts beneficially
owning in excess of 47% of the outstanding shares of Telemetrix voting capital
stock agreed with Technitrol to cause such shares to be voted in favor of the
disposition of Telemetrix's shares of the Common Stock or Preferred Stock, by
means of the Merger.
 
     On May 18, 1998, the Board met to consider the proposed letter of intent.
Following discussions with Legal Counsel, the Board determined that the draft
letter of intent fairly summarized the views of the parties. The Board further
noted that the letter of intent was, by its own terms, non-binding. The Board
directed that the Special Committee, in consultation with Legal Counsel,
complete the final negotiation of the specific language of the letter of intent
and work with management of the Company and representatives of Technitrol to
produce an appropriate press release concerning the signing of the letter of
intent. In addition, the Board expressed its view that it was in the best
interests of the Company and its stockholders to proceed to the
 
                                       19
<PAGE>   25
 
signing of a definitive merger agreement as soon as possible. Accordingly, the
Board directed the Special Committee, working in consultation with Legal
Counsel, to press Technitrol to complete negotiation and signing of the Merger
Agreement on an expedited basis. The letter of intent was executed and a press
release announcing such execution was issued prior to the opening of the Nasdaq
National Market on May 19, 1998.
 
     Prior to May 20, 1998, Legal Counsel had provided to the Board the original
draft of the Merger Agreement and a second draft, prepared by counsel to
Technitrol, that incorporated all of Technitrol's proposed changes to the Merger
Agreement. Between May 20, 1998 and May 26, 1998, the Special Committee,
management and Legal Counsel engaged in extensive negotiations with Technitrol
and its counsel concerning the Merger Agreement, the exhibits and disclosure
schedules thereto and the guaranty (the "Guaranty") of payment by Technitrol,
Inc. of the obligation of its subsidiary under the Merger Agreement to pay $3.10
in cash per share of Common Stock and $726.37 in cash per share of Preferred
Stock. Several drafts of the Merger Agreement were provided to the Special
Committee, which were discussed at length with Legal Counsel. Intensive
negotiation of the Merger Agreement ensued from May 20, 1998 through May 26,
1998. In connection with such negotiations, the parties also negotiated the size
of the break-up fee and the circumstances under which it would be paid by the
Company to Technitrol. On May 25, 1998, a draft of the Merger Agreement in form
and substance not materially different from the Merger Agreement ultimately
executed by the parties was sent to each member of the Board.
 
     On May 26, 1998 the Special Committee met to consider the Merger Agreement.
A representative of Legal Counsel presented a summary of the Merger Agreement
and many of the specific terms and conditions contained therein. The Special
Committee discussed with representatives of Legal Counsel the effect of a number
of the specific provisions of the Merger Agreement. The Special Committee
engaged in a discussion with representatives of the Financial Advisor concerning
the Financial Advisor's fairness opinion that would be delivered to the Board.
See Appendix B for the text of the opinion of the Financial Advisor. In the
context of discussing the fairness of the Merger Consideration to the holders of
Common Stock (other than Technitrol and its subsidiaries and affiliates) from a
financial point of view, the representatives of the Financial Advisor discussed
at length the extensive process of search, review and analysis that had been
undertaken by the Financial Advisor and the Special Committee. The Special
Committee discussed at length with the representatives of the Financial Advisor
their financial analysis of the Merger Consideration in light of the terms and
conditions of the Merger Agreement, with particular emphasis on the assumptions
that the Financial Advisor had made concerning growth rates, rates of return,
multiples of earnings and other measures of performance and premiums to market
prices that had been paid in other transactions. The representatives of the
Financial Advisor also expressed their view of other strategic alternatives,
including the continued independence of the Company. The Special Committee also
discussed with the representatives of the Financial Advisor their analysis,
based on a market survey and the Financial Advisor's experience, of the size of
the break-up fee and the circumstances in which it would be paid to Technitrol.
After management and the representatives of the Financial Advisor were excluded,
the Special Committee and representative of Legal Counsel reviewed the process
that had been undertaken by the Special Committee since its inception and the
terms and conditions of the Merger Agreement, in the context of the DGCL and
applicable securities laws. Following further discussion, the Special Committee
concluded that it was in the best interests of the Company and its stockholders
for the Company to be sold before any further deterioration had occurred in its
operating results. The Special Committee further concluded that having conducted
an exhaustive process, the proposal from Technitrol represented the best value
reasonably available for the Company and its stockholders. The Special Committee
unanimously passed a resolution to recommend that the Board adopt resolutions
approving the Merger Agreement, the exhibits and disclosure schedules thereto
and the Guaranty.
 
     Immediately following the adjournment of the meeting of the Special
Committee, a Board meeting convened, joined by the Company's Chief Financial
Officer and representatives of the Financial Advisor and Legal Counsel. A
representative of Legal Counsel discussed at length the terms and conditions in
the Merger Agreement, the exhibits and disclosure schedules thereto and the
Guaranty. The Board sought the advice of the Financial Advisor concerning the
terms of the Merger Agreement, in the context of similar transactions of which
the Financial Advisor had knowledge. The Financial Advisor presented its
fairness analysis and its opinion that, based upon the assumptions made, matters
considered and the limitations on the review
 
                                       20
<PAGE>   26
 
undertaken in connection therewith, the Merger Consideration, as of such date,
was fair to holders of Common Stock (other than Technitrol and its subsidiaries
and affiliates) from a financial point of view. A copy of the Financial
Advisor's opinion is attached as Appendix B to this Proxy Statement, and
stockholders should read this opinion in its entirety. The Board discussed with
the Financial Advisor the Financial Advisor's assumptions and analytical
methodologies. The Special Committee further reported to the Board that it had
adopted a resolution recommending that the Board adopt resolutions approving the
Merger Agreement, the exhibits and disclosure schedules thereto and the
Guaranty. Following further discussion, the Board adopted resolutions approving
the Merger Agreement, the exhibits and disclosure schedules thereto and the
Guaranty and directing the Company's management to execute and deliver the
Merger Agreement and to take other appropriate actions leading to the
consummation of the Merger. Such resolutions were adopted unanimously by the
four directors participating in the Board meeting. The fifth director, Mr.
Venter, was in transit between Johannesburg, South Africa and London, England at
the time of the Board meeting, and was unable to participate in the meeting, but
he subsequently expressed his approval of the Merger Agreement and the
transactions contemplated thereby.
 
     The Merger Agreement and the Guaranty were executed and delivered on May
26, 1998. A joint press release concerning such execution and delivery was
issued by GTI and Technitrol prior to the opening of the Nasdaq National Market
on May 27, 1998.
 
     Pursuant to its agreement with Technitrol, Telemetrix has called a meeting
of its stockholders to vote on the disposition of Telemetrix's Common Stock and
Preferred Stock through the Merger, and Telemetrix's board of directors has
recommended a vote for such disposition. Also pursuant to such agreement,
Telemetrix will vote its Common Stock and Preferred Stock in favor of the Merger
Agreement if Telemetrix's stockholders vote in favor of such disposition. GTI
will publicly announce the results of the Telemetrix stockholders meeting
promptly after it has taken place.
 
     Since May 27, 1998, neither the Company nor the Financial Advisor has
received any offers or proposals from any third parties.
 
GTI'S REASONS FOR THE MERGER; RECOMMENDATION OF THE SPECIAL COMMITTEE AND THE
BOARD OF DIRECTORS
 
     On May 26, 1998, the Special Committee unanimously recommended the approval
of the Merger Agreement and the transactions contemplated thereby, including the
Merger.
 
     On May 26, 1998, the Company Board (with Mr. Venter not participating
because he was then in transit from Johannesburg, South Africa to London,
England to attend a meeting of the board of directors of Telemetrix), based
upon, among other things, the unanimous recommendation and approval of the
Special Committee, the fairness opinion received from the Financial Advisor, and
the Board's independent review of the Merger Agreement and the other factors
described below, approved the Merger Agreement and the transactions contemplated
thereby, including the Merger, and it determined that the Merger is fair to, in
the best interests of, and produces the highest value reasonably obtainable to,
the stockholders of the Company and that it should recommend that the
stockholders of the Company adopt the Merger Agreement.
 
     Considerations of the Special Committee. In reaching its determination
referred to above, the Special Committee considered the following factors, each
of which, in the view of the Special Committee, supported such determinations:
 
          1. The assessment of the Company's management, the Board and the
     Special Committee that the Company could not long sustain its continuing
     operating losses. It was the determination of the Special Committee that,
     in order for GTI to compete more effectively in its market and increase
     stockholder value, it would be necessary to become or combine with a
     larger, diversified and better capitalized enterprise. Further, it was the
     Special Committee's assessment that it would be difficult for the Company
     to achieve this substantial increase in size either by acquisition or
     through internal growth. Based in part on the advice of the Financial
     Advisor, the Special Committee concluded that GTI likely would encounter
     difficulties raising the additional capital necessary to produce value to
     the Company's
 
                                       21
<PAGE>   27
 
     stockholders at levels similar to $3.10 per share of Common Stock in the
     reasonably foreseeable future. This determination was also due in part to
     the fact that many of the Company's competitors are substantially larger,
     more diversified and better capitalized than the Company and, as a result,
     possess greater ability to effect acquisitions, to maintain necessary
     technology programs and to hire and retain employees. Accordingly, the
     Special Committee concluded that a sale of GTI at the current time is in
     the best interests of GTI and its stockholders and that the Company, acting
     independently, would be unlikely to produce value to its stockholders at a
     level similar to or greater than $3.10 per share of Common Stock in the
     reasonably foreseeable future.
 
          2. The fact that the Special Committee and, at its direction, the
     Financial Advisor, had conducted a wide-ranging process to identify and
     contact potential acquirers or others interested in a strategic
     relationship or transaction with GTI. The Special Committee, working with
     management and the Financial Advisor, developed a detailed strategy of
     approach, first to potential strategic acquirers who were not competitors,
     then to other potential strategic partners, next to potential financial
     acquirers and last to competitors. In all, 15 such parties were contacted.
     The Special Committee held numerous meetings and carefully monitored the
     progress of such discussions and directed management and the Financial
     Advisor with respect to such discussions. In addition, in February 1998,
     GTI publicly announced that it had retained the Financial Advisor to
     explore strategic alternatives, including the possible sale of GTI. Any
     potential acquirer or strategic partner who had not yet been contacted was
     thereby given notice that GTI was potentially for sale. Accordingly, the
     Special Committee believed that a full and fair market test had been done
     to establish the arm's-length market value of GTI. Since the May 27, 1998
     announcement of the Merger Agreement, neither GTI nor the Financial Advisor
     has received any bid or indication of interest of any kind from any party.
 
          3. The history of the negotiations between the Special Committee and
     Technitrol, including (i) the Special Committee's belief (and Technitrol's
     clearly stated position) that Technitrol would not further increase the
     Merger Consideration, and, accordingly, $3.10 per share of Common Stock and
     $726.37 per share of Preferred Stock was, in the opinion of the Special
     Committee, the highest price that could be obtained from Technitrol and
     (ii) the Special Committee's belief that further negotiations concerning
     price with Technitrol could cause Technitrol to terminate negotiations with
     respect to the Merger.
 
          4. That the Merger Consideration of $3.10 per share of Common Stock
     represents: (i) a premium of approximately 34% over the $2.3125 per share
     closing price on May 12, 1998, which was seven days prior to the May 19,
     1998 public announcement of the fact that the Company had signed a letter
     of intent with Technitrol for the merger of the Company at $3.10 per share
     of Common Stock in cash; (ii) a premium of approximately 15.3% over the
     $2.6875 per share closing price on May 20, 1998, which was seven days prior
     to the May 27, 1998 public announcement (the "Announcement") of the fact
     that the Company had entered into a definitive agreement for the merger of
     the Company at $3.10 per share of Common Stock in cash; (iii) a premium of
     approximately 3.3% over the $3.00 per share closing price on April 27,
     1998, which was 30 days prior to the Announcement; and (iv) a premium of
     approximately 19.4% over the average closing price for the one-month period
     preceding the Announcement. In addition, the shares of Common Stock have
     not traded in Nasdaq's National Market higher than $3.10 per share of
     Common Stock since April 21, 1998. The $3.10 price per share of Common
     Stock and the $726.37 price per share of Preferred Stock are payable in
     cash, thus eliminating any uncertainties in valuing the consideration to be
     received by the holders of Common Stock and Preferred Stock.
 
          5. The terms and conditions of the Merger Agreement, including two key
     provisions negotiated by the Special Committee. First, Technitrol cannot
     refuse to complete the Merger because of a decline in the financial
     performance of GTI after May 26, 1998, even if such decline has a Material
     Adverse Effect (as defined in the Merger Agreement) on GTI. Second, GTI's
     Board of Directors retains the right to consider unsolicited superior
     proposals received from third parties, supply non-public information to
     such third parties, and terminate the Merger Agreement under certain
     circumstances if an unsolicited superior offer is received, subject to
     fulfillment of certain financial obligations to Technitrol. See "Merger
     Agreement."

<PAGE>   28
 
          6. The opinion of the Financial Advisor, addressed to the Special
     Committee and the Board, to the effect that, based upon the assumptions
     made, matters considered and the limitations on the review undertaken in
     connection therewith, the Merger Consideration of $3.10 per share of Common
     Stock, was, as of May 26, 1998, fair to holders of Common Stock (other than
     Technitrol and its subsidiaries and affiliates) from a financial point of
     view. See "Opinion of Cowen & Company" and the written opinion of the
     Financial Advisor attached as Appendix B.
 
          7. The possibility that the consideration the Company's stockholders
     might obtain in a future transaction was likely to be less advantageous
     than the Merger Consideration because of: the lower than expected Company
     earnings for the first fiscal quarter ended March 31, 1998, and the fiscal
     year ended December 31, 1997; the substantial uncertainty concerning
     whether the Company would be able to improve its performance in the
     nine-months ended September 30, 1998 or thereafter; the frequency with
     which the Company had, in the past, not met its internally projected
     results; and the uncertainty regarding the market for Local Area Network
     ("LAN") products, which account for in excess of 90% of the Company's
     revenues, and its effect on future Company earnings.
 
          8. The fact that Technitrol, Inc. was executing and delivering a
     guaranty of payment of the Merger Consideration by its subsidiary pursuant
     to the Merger Agreement, which increased the likelihood that the proposed
     acquisition would be consummated.
 
          9. While consummation of the Merger would result in the stockholders
     of the Company receiving a premium for their shares of Common Stock over
     the trading prices of such shares prior to the public announcement that the
     Company had signed a letter of intent for the sale of the Company at a
     price of $3.10 per share of Common Stock, consummation of the Merger would
     eliminate any opportunity for stockholders of the Company to participate in
     the potential future growth prospects, if any, of the Company. The Special
     Committee determined, however, that (a) the loss of opportunity is
     reflected in the price of $3.10 per share of Common Stock, and (b) there
     are continued substantial business risks associated with independent
     operation that could materially negatively affect the Company's ability to
     achieve the future operating results believed by the Special Committee to
     be necessary to achieve higher trading prices for the Common Stock.
 
     The foregoing discussion of the factors considered by the Special Committee
is not intended to be all-inclusive. In view of the variety of factors
considered in connection with its evaluation of the Merger, the Special
Committee did not find it practicable to and did not attempt to rank or assign
relative weights to the foregoing factors.
 
     Considerations of the Board. The members of the Board evaluated the factors
listed above under "Considerations of the Special Committee," in light of their
knowledge of the business, financial condition and prospects of the Company and
based upon the advice of management, the Financial Advisor and Legal Counsel. In
addition, the Board determined that the Merger Agreement was the result of a
process that was fair to the stockholders of the Company because, among other
things, (a) a Special Committee was formed consisting of members of the Board of
Directors who are neither employees of the Company nor affiliated with any
substantial stockholder of the Company nor any of the bidders, (b) the Special
Committee conducted more than 20 meetings during the period between the
formation of the Special Committee and the execution and delivery of the Merger
Agreement, during which meetings the Special Committee evaluated and analyzed
the bids, determined the negotiating strategy and reached informed conclusions
based, in part, on the advice of its independent financial and legal advisors,
(c) the Board and the Special Committee deliberated with respect both to the
Merger and the alternative strategies of remaining independent or seeking a
joint venture to which the Company would contribute substantially all of its
assets and personnel, and (d) the price of $3.10 per share of Common Stock and
the other terms and conditions of the Merger Agreement resulted from active
arm's-length bargaining between the Special Committee and Technitrol.
 
     IN LIGHT OF ALL THE FACTORS SET FORTH ABOVE, GTI'S BOARD OF DIRECTORS HAS
APPROVED THE MERGER AGREEMENT AND UNANIMOUSLY RECOMMENDS THAT
 
                                       23
<PAGE>   29
 
YOU VOTE TO ADOPT THE MERGER AGREEMENT. GTI'S BOARD OF DIRECTORS BELIEVES THAT
THE MERGER IS FAIR TO, AND IN THE BEST INTERESTS OF, GTI AND ITS STOCKHOLDERS.
 
OPINION OF COWEN & COMPANY
 
     Pursuant to an engagement letter dated January 22, 1998 (the "Financial
Advisor Engagement Letter"), the Special Committee retained Cowen & Company
("Cowen" or the "Financial Advisor") to serve as its financial advisor with
respect to the Merger. As part of this assignment, the Financial Advisor was
asked to render an opinion to the Special Committee and the Board as to the
fairness, from a financial point of view, of the financial terms of the Merger
to the holders of Common Stock other than Technitrol and its subsidiaries and
affiliates. The amount of consideration was determined through negotiations
between the Company and Technitrol and not pursuant to recommendations of the
Financial Advisor.
 
     On May 26, 1998, the Financial Advisor delivered certain of its written
analyses and its oral opinion to the Special Committee and the Board,
subsequently confirmed in writing as of the same date, to the effect that, as of
May 26, 1998, the financial terms of the Merger were fair, from a financial
point of view, to the holders of Common Stock other than Technitrol and its
subsidiaries and affiliates. The full text of the written opinion of the
Financial Advisor, dated May 26, 1998, is attached hereto as Appendix B and is
incorporated by reference. Holders of Common Stock are urged to read the opinion
in its entirety for the assumptions made, procedures followed, other matters
considered and limits of the review by the Financial Advisor. This summary of
the written opinion of the Financial Advisor set forth herein is qualified in
its entirety by reference to the full text of such opinion. The Financial
Advisor's analyses and opinion were prepared for and addressed to the Special
Committee and the Board and are directed only to the fairness, from a financial
point of view, of the financial terms of the Merger and do not constitute an
opinion as to the merits of the Merger or a recommendation to any stockholder as
to how to vote on the proposed Merger.
 
     The Financial Advisor was selected by the Special Committee as its
financial advisor, and to render an opinion to the Special Committee, because
the Financial Advisor is a nationally recognized investment banking firm and
because certain principals of the Financial Advisor have substantial experience
in transactions similar to the Merger and are familiar with the Company and its
businesses. As part of its investment banking business, the Financial Advisor is
regularly engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions and valuations for corporate and other
purposes.
 
     In arriving at its opinion, the Financial Advisor (i) reviewed the
Company's combined and consolidated financial statements for the fiscal years
ended December 31, 1995 through December 31, 1997, unaudited financial
statements for the fiscal quarter ended March 31, 1998, certain publicly
available filings with the Securities and Exchange Commission and certain other
relevant financial and operating data of the Company; (ii) reviewed the May 25,
1998 draft of the Merger Agreement provided to the Financial Advisor by
management of the Company; (iii) held meetings and discussions with management
and senior personnel of the Company to discuss the business, operations,
historical financial results and future prospects of the Company; (iv) reviewed
financial projections furnished to the Financial Advisor by the management of
the Company, including, among other things, the capital structure, sales,
operating income, net income, cash flow, capital requirements and other data of
the Company the Financial Advisor deemed relevant; (v) reviewed the operating
and financial results of the Company over the last three fiscal years and
compared its results with the operating and financial results of certain other
publicly traded companies which the Financial Advisor deemed relevant; (vi)
reviewed the public market valuation and trading multiples of the Company, and
compared the Company's trading multiples to the trading multiples of certain
other publicly traded companies which the Financial Advisor deemed relevant;
(vii) reviewed the historical prices and trading activity of the Common Stock
from May 22, 1997 to May 22, 1998 and from May 22, 1995 to May 22, 1998 and
compared the price performance of the Common Stock to the stock price
performance of certain other publicly traded companies which the Financial
Advisor deemed relevant over the period from May 22, 1997 to May 22, 1998;
(viii) compared the financial terms of the Merger with the financial terms of
the acquisitions of certain other companies which the Financial Advisor deemed
relevant, including a comparison of the premiums paid in the Merger with the
premiums paid in those other acquisitions; and (ix) conducted such other
studies, analysis,
                                       24
<PAGE>   30
 
inquiries and investigations as the Financial Advisor deemed appropriate. At the
request of the Company, the Financial Advisor solicited third-party indications
of interest in acquiring all or substantially all of the stock or assets of the
Company.
 
     In rendering its opinion, the Financial Advisor, with the consent of the
Special Committee and the Board, relied upon the Company's management with
respect to the accuracy and completeness of the financial and other information
furnished to it as described above or that was otherwise reviewed by it. With
respect to the financial projections furnished to the Financial Advisor by
management of the Company, the Financial Advisor assumed, with the consent of
the Special Committee and the Board, the attainability of the financial results
therein and that they were reasonably prepared on bases reflecting the best
currently available estimates and judgments of the Company's management as to
the future financial performance of the Company, and that such projections
provided a reasonable basis for the Financial Advisor's opinion. Because such
projections are inherently subject to uncertainty, none of the Financial
Advisor, the Board, the Special Committee, GTI or any other person assumes
responsibility for their accuracy. The Financial Advisor did not assume any
responsibility for independent verification of such information, including
financial information, nor did the Financial Advisor make or receive an
independent evaluation or appraisal of any of the properties or assets of the
Company. With respect to all legal matters relating to the Company, Technitrol
and the Merger, the Financial Advisor relied on the advice of legal counsel of
the Company. The Financial Advisor rendered no opinion with respect to such
matters.
 
     The Financial Advisor's opinion is necessarily based on general economic,
market, financial and other conditions as they exist on, and can be evaluated as
of, May 26, 1998, as well as the information then available to it. It should be
understood that, although subsequent developments may affect its opinion, the
Financial Advisor does not have any obligation to update, revise or reaffirm its
opinion. The Financial Advisor's opinion is limited to the fairness, from a
financial point of view, of the financial terms of the Merger to the holders of
Common Stock (other than Technitrol and its subsidiaries and affiliates). The
Financial Advisor expresses no opinion with respect to any other reasons, legal,
business or otherwise, that may support the decision of the Special Committee to
recommend to the Board the approval of, the decision of the Board to approve, or
the Company's decision to enter into, the Agreement.
 
     For purposes of rendering its opinion the Financial Advisor assumed, in all
respects material to its analysis, that the representations and warranties of
each party contained in the Merger Agreement are true and correct, that each
party will perform all of the covenants and agreements required to be performed
by it under the Merger Agreement and that all conditions to the consummation of
the Merger will be satisfied without waiver thereof. The Financial Advisor also
assumed that all governmental, regulatory or other consents and approvals
contemplated by the Merger Agreement will be obtained and that in the course of
obtaining those consents no restrictions will be imposed or waivers made that
would have a material adverse effect on the contemplated benefits of the Merger.
 
     The Financial Advisor also assumed, with the consent of the Special
Committee and the Board, that, prior to the effectiveness of the Merger, each
issued and outstanding share of Preferred Stock will be converted into 234.314
shares of Common Stock. The Financial Advisor did not express any opinion, and
did not conduct any analysis, with respect to a transaction that does not
contemplate the aforementioned conversion of all outstanding Preferred Stock
shares into shares of Common Stock. The Financial Advisor also expressed no
opinion as to the consideration that could have been received by the holders of
the Preferred Stock absent the conversion.
 
     The following is a summary of the principal financial analyses performed by
the Financial Advisor to arrive at its opinion. The Financial Advisor performed
certain procedures, including each of the financial analyses described below,
and reviewed with the Special Committee and the Board, the assumptions on which
such analyses were based and other factors, including the historical and
projected financial results of the Company. No limitations were imposed by the
Special Committee or the Board with respect to the investigations made or
procedures followed by the Financial Advisor in rendering its opinion.
 
     Stock Trading History. The Financial Advisor reviewed the historical market
prices and trading volumes of the Common Stock from May 22, 1997 to May 22, 1998
(the second to last trading day prior to
                                       25
<PAGE>   31
 
announcement of the Merger) and from May 22, 1995 to May 22, 1998. The Financial
Advisor also compared the closing price of the Common Stock with indices made up
of the average closing prices of each of the Core Comparable Companies, the
Small Cap Companies and the Large Cap Companies, respectively (the "Indices").
The companies included two companies in the magnetic-based electronic component
industry (Bel Fuse, Inc. and Technitrol, Inc.) (the "Core Comparable
Companies"); five small cap general electronic component companies (ACME
Electric Corp., Corcom, Inc., C.P. Clare Corporation, Methode Electronics, Inc.
and Spectrum Control, Inc.) (the "Small Cap Companies"); and five large cap
general electronic component companies (Artesyn Technologies, Inc., AVX
Corporation, Burr-Brown Corporation, Kemet Corporation and Vishay
Intertechnology, Inc.) (the "Large Cap Companies" and all of the companies
together, the "Selected Companies"). This information was presented solely to
provide the Special Committee and the Board with background information
regarding the stock price of GTI over the period indicated. The Financial
Advisor noted that over the last twelve months the high and low trading prices
for shares of Common Stock were $7.75 and $1.94, respectively, and that the
average closing price during this period was $5.28; and over the last three
years the high and low trading prices were $23.63 and $1.94, respectively. The
Financial Advisor also noted that the price of the Common Stock has fallen
during the twelve months ended May 22, 1998, while each of the three Indices has
increased during the twelve months ended May 22, 1998.
 
     The Financial Advisor noted that the consideration being offered in the
Merger represented premiums of 12.7%, 15.3% and 7.8% over the closing trading
prices of the Common Stock on May 22, 1998 ($2.75), May 15, 1998 ($2.69) and
April 24, 1998 ($2.88), respectively, and was 20.0% below the closing trading
price of the Common Stock on February 6, 1998 ($3.88) (the date immediately
prior to the announcement that GTI would explore strategic alternatives). The
Financial Advisor also noted that, after reducing the consideration being
offered in the Merger and the applicable closing trading price of the Common
Stock by the amount per share of cash on the balance sheet of GTI as of March
31, 1998, the corresponding premiums for such dates were 16.5%, 20.0%, 10.0% and
- -23.9%, respectively.
 
     Comparable Growth and Margin Analysis. To provide further contextual
information regarding the Company, the Financial Advisor analyzed the historical
median compound annual growth rates, over the last three fiscal years and for
the latest reported twelve months ("LTM") over the prior fiscal year, for
revenue, earnings before interest expense, income taxes, depreciation and
amortization ("EBITDA"), earnings before interest expense and income taxes
("EBIT") and net income and the projected median growth rates for net income for
each of the Core Comparable Companies, the Small Cap Companies and the Large Cap
Companies. The Financial Advisor also analyzed the median gross margin, EBIT and
net (net income) margins for each of the same groups of Selected Companies. The
Financial Advisor did not include Technitrol, Inc. and Vishay Intertechnology,
Inc. in this analysis as both companies have not restated their financials for
the last three fiscal years to reflect significant purchase acquisitions.
 
     Such analysis indicated that, for the Core Comparable Companies, the median
compound annual growth rates for revenue, EBITDA, EBIT and net income over the
last three fiscal years were 2.0%, 8.6%, 9.0% and 4.5%, respectively. The median
projected growth rate for net income from 1998 calendar year end to 1999
calendar year end (based on projected net income data calculated by First Call)
was 16.0%; and the average gross, EBIT and net margins were 29.5%, 11.4% and
11.8%, respectively. For the Small Cap Companies, the median compound annual
growth rates for revenue, EBITDA, EBIT and net income over the last three fiscal
years were 9.5%, 8.5%, 7.1% and 9.6%, respectively. The median projected growth
rate for net income from 1998 calendar year end to 1999 calendar year end was
not meaningful as 1999 calendar year end projected earnings were not available
for any of the Small Cap Companies; and the average gross, EBIT and net margins
were 31.7%, 10.0% and 6.4%, respectively. For the Large Cap Companies, the
median compound annual growth rates for revenue, EBITDA, EBIT and net income
over the last three fiscal years were 2.5%, 2.6%, -0.4% and 2.3%, respectively.
The median projected growth rate for net income from 1998 calendar year end to
1999 calendar year end (based on projected net income data calculated by First
Call) was 18.4%; and the average gross, EBIT and net margins were 28.7%, 15.5%
and 10.0%, respectively.
 
     The corresponding growth rate in revenue for GTI was -15.2%. The
corresponding growth rates for EBITDA, EBIT, net income, and projected net
income for GTI were each not meaningful given GTI's
 
                                       26
<PAGE>   32
 
historical and projected net and operating losses. The corresponding gross, EBIT
and net margins for GTI were 23.4%, -2.1% and -2.0%, respectively.
 
     Such analysis for the LTM over the prior fiscal year indicated that, for
the Core Comparable Companies, the median growth rates for revenue, EBITDA,
EBIT, and net income were 17.8%, 33.2%, 40.5% and 34.6%, respectively. The
corresponding gross, EBIT and net margins were 31.9%, 13.5% and 13.6%,
respectively. For the Small Cap Companies, the median growth rates for revenue,
EBITDA, EBIT, and net income were 12.1%, 28.9%, 32.3% and 20.1%, respectively.
The corresponding gross, EBIT and net margins were 31.0%, 10.7% and 7.5%,
respectively. For the Large Cap Companies, the median growth rates for revenue,
EBITDA, EBIT, and net income were 20.6%, 30.9%, 31.8% and 26.2%, respectively.
The corresponding gross, EBIT and net margins were 28.3%, 14.3% and 9.5%,
respectively.
 
     The corresponding growth rate in revenue for GTI was -19.8%. The
corresponding growth rates for EBITDA, EBIT and net income for GTI were each not
meaningful given GTI's historical net and operating losses. The corresponding
gross, EBIT and net margins for GTI were 18.7%, -9.7% and -10.0%, respectively.
 
     Discounted Cash Flow Analysis. The Financial Advisor estimated the range of
values for the Common Stock based upon the discounted present value of the
projected after-tax free cash flows of GTI for the fiscal years ended December
31, 1998 through December 31, 2001, and of the terminal value of the Company at
December 31, 2002. After tax free cash flow was calculated by taking projected
EBIT and subtracting from such amount projected taxes, capital expenditures,
changes in working capital and changes in other assets and liabilities and
adding back projected depreciation and amortization (the "Free Cash Flows").
This analysis was based upon operating (EBIT) cash flow projections provided by
GTI management. In performing this analysis, the Financial Advisor utilized
discount rates ranging from 15.0% to 20.0% based on GTI's weighted average cost
of capital of 17.2% as of May 22, 1998. In calculating the terminal value of the
Company, the Financial Advisor utilized perpetual growth rates ranging from 3.0%
to 5.0% applied to 2001 Free Cash Flow for GTI. Utilizing this methodology,
GTI's fully-diluted equity value ranged from $1.60 to $2.60 per share.
 
     Discounted Prospective Future Earnings Analysis. The Financial Advisor also
analyzed potential Common Stock prices one year from May 26, 1998 and two years
from May 26, 1998, based on management's projected earnings in 1999 and in 2000
and prospective price to earnings ("P/E") multiples ranging from 12.5x to 22.5x.
The Financial Advisor noted that as of May 22, 1998, the 1998 P/E multiples for
the Core Comparable Companies ranged from 15.4x to 16.8x with a median and mean
of 16.1x. The Financial Advisor observed that, on the basis of the Company's
earnings per share projections in 1999, GTI would have to achieve a 1999 P/E
multiple of greater than 22.5x in order to achieve, by May 26, 1999, a price
greater than $3.00 per share of Common Stock.
 
     The Financial Advisor also observed that in 2000, on the basis of the
Company's earnings projections (which the Financial Advisor noted represents a
161% increase over the 1999 earnings projections), GTI must achieve a P/E
multiple greater than 16.0x in order to achieve a price per share of Common
Stock that has a present value greater than $3.10 per share. The Financial
Advisor assumed a discount rate of approximately 17% in calculating the present
value of the Company's prospective share price. The Financial Advisor observed
that this discount rate approximated the Company's cost of equity of 17.5% as of
May 22, 1998.
 
     Analysis of Certain Transactions. The Financial Advisor reviewed the
financial terms, to the extent publicly available, of nine transactions
involving the acquisition of companies in the electronics industry (the "EI
Transactions") and 3 transactions involving the acquisition of companies in the
magnetic-based components industry (the "MBC Transactions" and, collectively
with the EI Transactions, the "Selected Transactions"), in each case which were
announced or completed since January 1, 1992. The EI Transactions consisted of
(listed as acquiror/target): Computer Products Inc./Zytec Corporation; Cooper
Industries, Inc./ Coiltronics, Inc.; Computer Products, Inc./Elba Group; Thomas
& Betts Corporation/Augat Inc.; AMP, Inc./ M/A-Com, Inc.; Vishay
Intertechnology, Inc./Vitramon, Inc.; Avnet, Inc./Hall-Mark Electronics Corp.;
Hicks, Muse & Co./DuPont Co. -- Connector Systems; and Vishay Intertechnology,
Inc./Sprague Technologies Inc. -- Component Operations. The MBC Transactions
consisted of (listed as acquiror/target): Technitrol, Inc./Northern Telecom
Ltd. -- Magnetic Components; Technitrol, Inc./Pulse Engineering Inc.; and
Technitrol, Inc./The Fil-Mag Group (the "MBC Transactions").
                                       27
<PAGE>   33
 
     The Financial Advisor reviewed the market capitalization of common stock
plus total debt less cash and equivalents ("Enterprise Value") paid in the
Selected Transactions as a multiple of LTM revenues and also examined the
multiples of equity value paid in the Selected Transactions to book value and
tangible assets. In addition, the Financial Advisor reviewed the premium of the
offer price over the trading prices one trading day, five trading days, twenty
trading days and thirty trading days prior to the announcement date of the
Selected Transactions.
 
     Such analysis indicated that the Enterprise Value paid, as a multiple of
LTM revenues, ranged, for the Selected Transactions, from 0.43x to 1.68x, with a
median of 0.96x and a mean of 0.92x (excluding one of the Selected Transactions
for which information was not available); for the MBC transactions, from 0.43x
to 0.55x, with a median of 0.46x and a mean of 0.48x; and for the EI
Transactions, from 0.55x to 1.68x, with a median of 1.05x and a mean of 1.08x.
The Financial Advisor noted that the corresponding multiple of LTM revenues
implied by Technitrol's offer is 0.38x.
 
     Such analysis also indicated that the equity value paid, as a multiple of
book value, ranged, for the Selected Transactions, from 0.97x to 8.16x book
value, with a median of 2.75x and a mean of 3.37x (excluding five of the
Selected Transactions for which information was not available); for the MBC
Transactions, was 1.09x (information was available for only one of the MBC
Transactions); and for the EI Transactions, from 0.97x to 8.16x, with a median
of 3.12x and a mean of 3.75x. Such analysis also indicated that the equity value
paid as a multiple of tangible assets, ranged, for the Selected Transactions,
from 0.80x to 3.52x, with a median of 1.36x and a mean of 1.61x (excluding five
of the Selected Transactions for which information was not available); for the
MBC Transactions, was 0.86x (information available for only one of the MBC
Transactions); and for the EI Transactions, from 0.80x to 3.52x, with a median
of 1.51x and a mean of 1.73x. The corresponding multiples of book value and
tangible assets implied by Technitrol's offer are 0.58x and 0.60x, respectively.
 
     Such analysis also indicated that, for the Selected Transactions, the
premium of the offer price, at announcement, one trading day, five trading days,
twenty trading days, and thirty trading days prior to the announcement date
ranged from 8.9% to 50.0%, 8.0% to 55.6%, 5.4% to 74.2% and 25.9% to 74.7%,
respectively, with medians and means of 33.5% and 31.6%, 43.7% and 35.6%, 36.3%
and 39.3%, and 38.4% and 43.4%, respectively. The corresponding premiums implied
by Technitrol's offer are 12.7%, 15.3%, 7.8% and -17.3%.
 
     Although the Selected Transactions were used for comparison purposes, none
of such transactions is directly comparable to the Merger, and none of the
companies in such transactions is directly comparable to GTI or Technitrol (with
the exception of the MBC Transactions in which Technitrol was the acquiring
company). Accordingly, an analysis of the results of such a comparison is not
purely mathematical but instead involves complex considerations and judgments
concerning differences in historical and projected financial and operating
characteristics of the companies involved and other factors that could affect
the acquisition value of such companies or GTI to which they are being compared.
 
     Analysis of Certain Publicly Traded Companies. To provide contextual data
and comparative market information, the Financial Advisor compared selected
historical operating and financial data and ratios for GTI to the corresponding
data and ratios of each of the Selected Companies. Such data and ratios included
the Enterprise Value of such companies as a multiple of LTM revenues, and the
market capitalization of common stock of such companies as a multiple of the
book value of common shareholders' equity. The Financial Advisor also examined
the ratios of the current prices of such companies to the estimated 1999
calendar year earnings per share ("EPS") (as estimated by Institutional Brokers
Estimating System ("IBES") and First Call).
 
     Such analysis indicated that, for the Core Comparable Companies, the
Enterprise Value as a multiple of LTM revenues ranged from 1.54x to 1.67x with a
median of 1.60x and a mean of 1.60x, and that, for all the Selected Companies,
the Enterprise Value as a multiple of LTM revenues ranged from 0.50x to 3.43x,
with a median of 1.23x and a mean of 1.34x. The Financial Advisor noted that the
corresponding multiple of LTM revenues implied by Technitrol's offer is 0.38x.
 
                                       28

     Such analysis also indicated that, for the Core Comparable Companies, the
equity value as a multiple of book value ranged from 2.13x to 4.37x, with a
median of 3.25x and a mean of 3.25x, and the multiple of current prices of the
Core Comparable Companies to their estimated 1999 calendar year EPS was 14.5x
(estimated 1999 calendar year earnings were available for only one of the Core
Comparable Companies). Such analysis also indicated that, for the Selected
Companies, the equity value as a multiple of book value ranged from 1.34x to
4.37x, with a median of 2.15x and a mean of 2.49x; the price per share ranged
from 10.6x to 18.8x estimated 1999 calendar year EPS, with a median of 13.3x and
a mean of 14.0x (excluding eight of the Selected Companies for which there were
no estimated 1999 calendar year earnings available). The Financial Advisor noted
that the corresponding multiples implied by Technitrol's offer are 0.58x book
value and 30.6x estimated 1999 calendar year EPS.
 
     Although the Selected Companies were used for comparison purposes, none of
such companies are directly comparable to GTI. Accordingly, an analysis of the
results of such a comparison is not purely mathematical but instead involves
complex considerations and judgments concerning differences in historical and
projected financial and operating characteristics of the Selected Companies and
other factors that could affect the public trading value of the Selected
Companies or GTI to which they are being compared.
 
     The summary set forth above does not purport to be a complete description
of all the analyses performed by the Financial Advisor. The preparation of a
fairness opinion involves various determinations as to the most appropriate and
relevant methods of financial analyses and the application of these methods to
the particular circumstances and, therefore, such an opinion is not readily
susceptible to partial analysis or summary description. The Financial Advisor
did not attribute any particular weight to any analysis or factor considered by
it, but rather made qualitative judgments as to the significance and relevance
of each analysis and factor. Accordingly, notwithstanding the separate factors
summarized above, the Financial Advisor believes, and has advised the Special
Committee and the Board, that its analyses must be considered as a whole and
that selecting portions of its analyses and the factors considered by it,
without considering all analyses and factors, could create an incomplete view of
the process underlying its opinion. In performing its analyses, the Financial
Advisor made numerous assumptions with respect to industry performance, business
and economic conditions and other matters, many of which are beyond the control
of GTI and Technitrol. These analyses performed by the Financial Advisor are not
necessarily indicative of actual values or future results, which may be
significantly more or less favorable than suggested by such analyses. In
addition, analyses relating to the value of businesses do not purport to be
appraisals or to reflect the prices at which businesses or securities may
actually be sold. Accordingly, such analyses and estimates are inherently
uncertain and, they are subject to significant business, economic, competitive,
regulatory and other uncertainties and contingencies, all of which are difficult
or impossible to predict and are beyond the control of the Financial Advisor and
GTI. As mentioned above, the analyses supplied by the Financial Advisor and its
opinion were among several factors taken into consideration by the Special
Committee and the Board in making their respective decisions to recommend the
approval of, and to approve, the Merger Agreement and should not be considered
as determinative of such decisions.
 
     Pursuant to the Financial Advisor Engagement Letter, GTI has agreed to pay
certain fees to the Financial Advisor for its financial advisory services
provided in connection with the Merger, a significant portion of which is
contingent upon the consummation thereof. If the Merger is consummated, the
Financial Advisor will be entitled to receive an aggregate transaction fee in an
amount equal to approximately $600,000, less a retainer fee of $50,000 paid upon
execution of the Financial Advisor Engagement Letter. Additionally, GTI has
agreed to reimburse the Financial Advisor for its out-of-pocket expenses
(including the reasonable fees and expenses of its counsel) incurred or accrued
during the period of, and in connection with, the Financial Advisor's
engagement. GTI has also agreed to indemnify the Financial Advisor against
certain liabilities, including liabilities under the federal securities laws,
relating to or arising out of services performed by the Financial Advisor as
financial advisor to the Special Committee in connection with the Merger, unless
it is finally judicially determined that such liabilities arose out of the
Financial Advisor's gross negligence or willful misconduct. The terms of the fee
arrangement with the Financial Advisor, which are customary in transactions of
this nature, were negotiated at arm's length between the Special Committee and
the Financial
 
                                       29
<PAGE>   35
 
Advisor, and the Board was aware of such arrangement, including the fact that a
significant portion of the aggregate fee payable to the Financial Advisor is
contingent upon consummation of the Merger.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     In considering the Merger, stockholders should be aware that certain
current and prior directors and officers of GTI have interests in the Merger, as
described below.
 
     Change of Control Stay Bonuses. Upon closing of the Merger, Albert J.
Hugo-Martinez (the Company's Chief Executive Officer and a director) will
receive a lump sum payment equal to eighteen months of his base salary, and five
other officers of the Company will receive a lump sum cash payment equal to nine
months of their respective base salaries, assuming that they are still employed
by the Company at that time. These payments supersede and replace any other
severance payment to which these employees might otherwise be entitled. Bruce C.
Myers (the Company's Chief Financial Officer) will receive at closing a lump sum
cash payment of approximately $75,000 in addition to the nine month amount
described above.
 
     Options. Certain of the GTI officers and directors hold options to acquire
Common Stock, all of which options are at an exercise price which is greater
than $3.10 per share. As a result, no officer or director will profit from such
options.
 
     Indemnification. The Merger Agreement provides that all rights to
indemnification and advancement of expenses existing in favor of any present or
former director or officer of GTI, as provided in (i) GTI's certificate of
incorporation or bylaws, or (ii) certain indemnification agreements identified
in the Merger Agreement as in effect on the date thereof, shall survive the
Merger with respect to matters occurring at or prior to the Effective Time.
Pursuant to the Merger Agreement, Technitrol has agreed that it will indemnify
and hold harmless the present and former officers and directors of GTI in
respect of acts or omissions occurring prior to the Effective Time, subject to
limitations imposed under applicable law. Technitrol has agreed to maintain the
existing GTI policy of directors' and officers' liability insurance for a period
of six years after the Effective Time. Technitrol, Inc. has guaranteed payment
of the indemnity.
 
     Repayment of Telemetrix Loan. The Merger Agreement requires that the
Company repay its outstanding loan from Telemetrix immediately prior to the
Effective Time, as part of Technitrol's plan to replace the Company's existing
financing facilities. The outstanding principal balance on the Telemetrix loan
was $1.25 million as of May 27, 1998. Absent this requirement, $625,000
principal amount of the loan is due in August 1998 and $625,000 principal amount
of the loan is due in February 1999. Accordingly, the Merger Agreement will have
the effect of Telemetrix receiving its payments earlier than might otherwise
have occurred.
 
     Liquidity for Telemetrix. Consummation of the Merger will provide liquidity
to Telemetrix for its substantial block of Common Stock and Preferred Stock,
which liquidity might not otherwise be available to Telemetrix.
 
MERGER AGREEMENT
 
     The following summary of the Merger Agreement is subject to, and qualified
in its entirety by, the complete text of the Merger Agreement, which is attached
to this Proxy Statement as Appendix A. The terms of the Merger Agreement are the
result of arm's-length negotiations between GTI and Technitrol.
 
     Terms of the Merger. At the Effective Time, and subject to and upon the
terms and conditions of the Merger Agreement and the DGCL, Acquisition will be
merged with and into GTI, the separate corporate existence of Acquisition will
cease, and GTI will continue as the surviving corporation.
 
     Subject to and immediately following the receipt of the vote of
stockholders of GTI and the satisfaction or waiver of the conditions to the
consummation of the Merger set forth in the Merger Agreement, the parties shall
cause the Merger to be consummated by filing a certificate of merger as
contemplated by the DGCL. The Merger shall be effective at the time the
certificate of merger is filed with the Delaware Secretary of State or such
other time as specified in the certificate of merger.
 
                                       30
<PAGE>   36
 
     The Merger Agreement provides that the certificate of incorporation of
Acquisition, as in effect immediately prior to the Effective Time, shall be the
certificate of incorporation of GTI immediately after the Effective Time. The
Merger Agreement provides that the bylaws of Acquisition, as in effect
immediately prior to the Effective Time, shall be the bylaws of GTI immediately
after the Effective Time.
 
     The directors and officers of Acquisition immediately prior to the
Effective Time shall be the directors and officers of GTI immediately after the
Effective Time.
 
     Conversion of Shares in the Merger. At the Effective Time, each share of
Preferred Stock which is issued and outstanding immediately prior to the
Effective Time (other than shares of Preferred Stock as to which appraisal
rights are exercised) shall, by virtue of the Merger and without any action on
the part of the holder thereof, be converted into and represent the right to
receive, in cash, $726.37 per share of Preferred Stock. At the Effective Time,
each share of Common Stock which is issued and outstanding immediately prior to
the Effective Time (other than shares of Common Stock as to which appraisal
rights are exercised) shall, by virtue of the Merger and without any action on
the part of the holder thereof, be converted into and represent the right to
receive, in cash, $3.10 per share of Common Stock.
 
     At the Effective Time, each share of Common Stock held in the treasury of
GTI immediately prior to the Effective Time shall be canceled and cease to
exist, and no payment shall be made with respect thereto.
 
     Appraisal Rights. Notwithstanding any provision of the Merger Agreement to
the contrary, any shares of Common Stock outstanding immediately prior to the
Effective Time held by a holder who has demanded and perfected the right of
appraisal of those shares in accordance with the provisions of Section 262 of
the DGCL and as of the Effective Time has not withdrawn or lost such right to
such appraisal ("Dissenting Shares") shall not be converted into or represent a
right to receive a cash payment pursuant to the Merger Agreement, but the holder
shall only be entitled to such rights as are granted by the DGCL. See "Appraisal
Rights." If a holder of shares of Common Stock who demands appraisal of those
shares under the DGCL effectively withdraws or loses (through failure to perfect
or otherwise) the right of appraisal, then, as of the Effective Time or the
occurrence of such event, whichever last occurs, those shares shall be converted
into and represent only the right to receive $3.10 per share, without interest,
upon compliance with the provisions, and subject to the limitations, of the
Merger Agreement. The Merger Agreement requires that GTI shall give Technitrol
(a) prompt notice of any written demands for appraisal of any shares of Common
Stock, attempted withdrawals of such demands, and any other instrument served
pursuant to the DGCL and received by GTI relating to stockholders' rights of
appraisal, and (b) the opportunity to participate in all negotiations and
proceedings with respect to demands for appraisal under the DGCL. GTI shall not,
except with the prior written consent of Technitrol, voluntarily make any
payment with respect to any demands for appraisal of Common Stock or offer to
settle or settle any such demands.
 
     Options and Warrants. At or immediately prior to the Effective Time, all
options and warrants (the "Stock Rights") to purchase shares of Common Stock
that were granted under any employee stock option or compensation plan, or other
arrangement shall be canceled. No holder of Stock Rights shall be entitled to
receive any amount on account of such cancellation because each Stock Right is
exercisable at a price in excess of $3.10 per share of Common Stock.
 
     Payment of Shares. At the Effective Time, Technitrol shall deposit, in
immediately available funds, with Registrar and Transfer Company (the "Payment
Agent"), an amount sufficient to allow the Merger Consideration to be paid to
the holders of each share of Common and Preferred Stock (such sum being
hereinafter referred to as the "Merger Fund"). Out of the Merger Fund, the
Payment Agent shall, pursuant to instructions from the holders of Common and
Preferred Stock, make the payments of the Merger Consideration referred to in
the Merger Agreement. Any amount remaining in the Fund one year after the
Effective Time shall be refunded to Parent, upon demand, and Parent shall remain
liable for payment of the Merger Consideration.
 
     In the event any certificate or certificates representing Common or
Preferred Stock are lost, stolen or destroyed, then the person claiming such
fact must provide (i) an affidavit to that effect and (ii) a suitable
 
                                       31
<PAGE>   37
 
indemnity or bond, if required by Parent or the Payment Agent. Upon receipt and
processing of such documents, the amount owing to such person shall be paid to
such person.
 
     At and after the Effective Time, all shares of Common and Preferred Stock
issued and outstanding immediately prior to the Effective Time shall be canceled
and cease to exist, and each holder of a certificate or certificates that
represented shares of Common or Preferred Stock issued and outstanding
immediately prior to the Effective Time shall cease to have any rights as a
stockholder of GTI with respect to the shares of Common or Preferred Stock
represented by such certificate or certificates, except for the right to
surrender such holder's certificate or certificates in exchange for the payment
provided pursuant to the Merger Agreement or to perfect such holder's right to
receive payment for such holder's shares pursuant to the DGCL if such holder has
validly exercised and not withdrawn or lost such holder's right to receive
payment for such holder's shares pursuant to the DGCL.
 
     DETAILED INSTRUCTIONS, INCLUDING A TRANSMITTAL LETTER, WILL BE MAILED TO
STOCKHOLDERS PROMPTLY FOLLOWING THE EFFECTIVE TIME AS TO THE METHOD OF
EXCHANGING CERTIFICATES FORMERLY REPRESENTING SHARES OF COMMON STOCK OR
PREFERRED STOCK FOR THE MERGER CONSIDERATION. STOCKHOLDERS SHOULD NOT SEND
CERTIFICATES REPRESENTING THEIR SHARES OF COMMON STOCK OR PREFERRED STOCK TO THE
PAYMENT AGENT OR GTI PRIOR TO RECEIPT OF THE TRANSMITTAL LETTER.

from the date of the Merger Agreement through the Effective Time, GTI will
conduct its operations only in the ordinary course of business consistent with
past practices, and to the extent consistent therewith, with no less diligence
and effort than would have been applied in the absence of the Merger Agreement.

any material election in respect of Taxes; or (xvii) take, or agree to take, any

     Solicitations and Superior Proposals. The Company has covenanted that
neither the Company nor any of its subsidiaries shall, nor shall the Company
authorize or permit any of its or their respective officers, directors,
employees, representatives, agents, investment bankers, subsidiaries and
affiliates to, directly or indirectly, solicit, initiate, engage or participate
in discussions or negotiations with, or disclose or afford access to non-public
information concerning the Company and its subsidiaries to or otherwise assist,
encourage or cooperate with or enter into any agreement or understanding with
any person or group (other than Parent and Acquisition or any designees of
Parent and Acquisition) concerning any Third Party Acquisition Proposal;
provided, however, that such covenant shall not prevent the Board from taking
and disclosing to the Company's stockholders a position contemplated by Rules
14d-9 and 14e-2 promulgated under the Exchange Act with regard to any tender
offer. The Board shall not withdraw or amend its recommendation of the Merger
Agreement or approve or recommend, or cause the Company to enter into any
agreement with respect to, any Third Party Acquisition Proposal, and the Company
shall and shall cause its respective officers, directors, employees,
representatives, agents, investment bankers, subsidiaries and affiliates not to
make or authorize any statement, recommendation or solicitation in support of
any Third Party Acquisition Proposal. Notwithstanding anything to the contrary
provided in the Merger Agreement, the Board may participate in negotiations with
a Third Party, furnish information to a Third Party or amend or withdraw its
recommendation of the adoption of the Merger Agreement or approve or recommend a
Superior Proposal, but only after a Third Party shall have delivered to the
Company in writing an unsolicited, bona fide Third Party Acquisition Proposal
that the Board by a majority vote determines in its good faith judgment (after
consultation with its principal advisors, including a financial advisor of
nationally recognized reputation, which shall be deemed to include the Financial
Advisor) to be more favorable to the Company's stockholders than the Merger (a
"Superior Proposal") and for which financing, to the extent required, is then
committed or which, in the good faith reasonable judgment of the Board (based on
the advice of a financial advisor of nationally recognized reputation) is
reasonably capable of being financed by such Third Party and which is probable
to be consummated in accordance with its terms. In the event the Company
receives a Superior Proposal, the Company will (i) immediately give written
notice to Parent (a "Notice of Superior Proposal") advising Parent that the
Board has received an unsolicited bona fide Superior Proposal, specifying the
material terms and conditions of such Superior Proposal and identifying the
person making such Superior Proposal and (ii) give Parent five business days
from its receipt of the Notice of Superior Proposal to make an offer which the
Board by a majority vote determines in its good faith judgment (after
consultation with its principal advisors, including a financial advisor of
nationally recognized reputation) to be at least as favorable to the Company's
stockholders as such Superior Proposal, in which event the Board shall accept
such offer from Parent unless, within five business days of the Company's
receipt of such offer from Parent, the Company receives a Third Party
Acquisition Proposal that the Board, by a majority vote, determines in its good
faith judgment (after
 
                                       33
<PAGE>   39
 
consultation with its principal advisors, including a financial advisor of
nationally recognized reputation) to be more favorable to the Company's
stockholders than such offer from Parent. "Third Party" means any person, entity
or group (which includes a "person" as such term is defined in Section 13(d)(3)
of the Exchange Act), other than Parent, Acquisition or any affiliate thereof.
"Third Party Acquisition Proposal" means a proposal to the Company by a Third
Party for a transaction that would include any of the following events: (i) the
acquisition of the Company by merger or otherwise by any Third Party; (ii) the
acquisition by a Third Party of more than 50% of the total assets of the Company
and its subsidiaries taken as a whole; or (iii) the acquisition by a Third Party
of 50% or more of the outstanding Common Stock or Preferred Stock.
 
     Additional Covenants. Pursuant to the Merger Agreement, GTI has covenanted
to: (i) prepare and file with the Securities and Exchange Commission this Proxy
Statement and all other filings with the Securities and Exchange Commission
required to be filed by the Company; (ii) convene a special meeting of GTI
stockholders as soon as practicable to vote upon adoption of the Merger
Agreement; (iii) permit Technitrol to have access to GTI's officers, employees,
agents, independent auditors, representatives, properties, books and records;
and (iv) use all reasonable efforts to obtain any third party consents required
to effectuate the Merger Agreement.
 
     Parent has covenanted to cause: (i) at the Effective Time, the payment of
funds sufficient to pay the Merger Consideration; and (ii) after the Effective
Time, GTI to honor all GTI employment, severance, consulting and other
compensation contracts with any current or former GTI director, officer or
employee, and all provisions for vested benefits under employee benefit plans,
and, for one year after the Effective Time, to extend benefit plans that, in the
aggregate, are substantially similar to the GTI benefit plans in effect
immediately prior to the Effective Time. The covenant contained in the preceding
clause (ii) does not obligate GTI or Parent to continue to employ any person who
is not a party to an employment agreement. Technitrol, Inc. has guaranteed
Parent's covenant to pay the Merger Consideration.
 
     GTI, Parent and Acquisition each have covenanted to: (i) make any filings
required by the HSR Act; (ii) give any required notices concerning breaches of
its own representations and warranties in the Merger Agreement; (iii) make a
joint press release concerning the Merger; and (iv) use all commercially
reasonable efforts to take all actions and to do all things necessary in order
to consummate and make effective the transactions contemplated by the Merger
Agreement.
 
     Conditions to the Merger. The obligations of GTI and Technitrol to complete
the Merger are subject to a number of conditions. If these conditions are not
satisfied or waived, the Merger will not be completed: (i) approval of the
Merger Agreement by holders of a majority of the outstanding shares of Common
Stock and holders of at least two-thirds of the outstanding shares of Preferred
Stock, voting as separate classes; (ii) expiration or earlier termination of the
waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976
("HSR") (early termination was granted and became effective on June 19, 1998);
and (iii) no statute, rule, regulation, executive, order, decree, ruling or
injunction shall have been enacted, entered, promulgated or enforced by any
United States court or United States governmental authority which prohibits,
restrains, enjoins or restricts the consummation of the Merger.
 
     Several additional conditions exist that must be met to require Technitrol
to complete the Merger: (i) the representations of the Company contained in the
Merger Agreement or in any other document delivered pursuant thereto shall be
true and correct at and as of the Effective Time with the same effect as if made
at and as of the Effective Time (except to the extent the representations
specifically related to an earlier date, in which case such representations
shall be true and correct as of such earlier date), provided that the
representations of the Company and its subsidiaries which are not qualified by
materiality or Material Adverse Effect (as defined in the Merger Agreement)
shall be deemed for all purposes of the Merger Agreement to be true and correct
if, in the aggregate the breach of all such representations, if any, do not have
a Material Adverse Effect on the Company or the validity of the Merger; (ii)
each of the covenants and obligations of the Company to be performed at or
before the Effective Time pursuant to the terms of the Merger Agreement shall
have been duly performed in all material respects at or before the Effective
Time; (iii) the Company shall have obtained the consent or approval of each
person whose consent or approval shall be required in connection with the
transactions contemplated by the Merger Agreement under any loan or credit
agreement,
 
                                       34
<PAGE>   40
 
license, note, mortgage, indenture, lease or other agreement or instrument,
except those for which failure to obtain such consents and approvals would not,
individually or in the aggregate, have a Material Adverse Effect on the Company
or the validity of the Merger; (iv) receipt of an opinion of legal counsel to
the Company as to certain matters set forth in Exhibit B to the Merger
Agreement, and (v) GTI stockholders perfecting appraisal rights hold no more
than 10% of the outstanding shares of Common Stock of GTI, assuming for purposes
of such calculation the conversion to shares of Common Stock of all outstanding
shares of Preferred Stock.
 
     Notwithstanding the above, the first three conditions, in the immediately
preceding paragraph, to Technitrol's obligation to complete the Merger will be
deemed satisfied if such conditions would have been satisfied but for the
occurrence, between May 26, 1998 and the closing date of the Merger, of a
reduction, compared to the first quarter of fiscal year 1998, in the earnings
before interest, taxes, depreciation and amortization of the Company and its
subsidiaries, on a consolidated basis ("EBITDA") that has a Material Adverse
Effect on the Company, and the business and financial events resulting in such
reduction in EBITDA were not themselves initiated by one or more independent
breaches by the Company of the representations and warranties of the Company
contained in the Merger Agreement.
 
     Additional conditions exist that must be met to obligate GTI to complete
the Merger: (i) the representations of Parent and Acquisition contained in the
Merger Agreement or in any other document delivered pursuant thereto shall be
true and correct at and as of the Effective Time with the same effect as if made
at and as of the Effective Time (except to the extent such representations
specifically related to an earlier date, in which case such representations
shall be true and correct as of such earlier date), provided that the
representations of Parent and Acquisition which are not qualified by materiality
or Material Adverse Effect shall be deemed for all purposes of this Agreement to
be true and correct if, in the aggregate the breaches of all such
representations, if any, do not have a Material Adverse Effect on Parent or
Acquisition or the validity of the Merger; (ii) each of the covenants and
obligations of Parent and Acquisition to be performed at or before the Effective
Time pursuant to the terms of this Agreement shall have been duly performed in
all material respects at or before the Effective Time; (iii) Parent shall have
obtained the consent or approval of each person whose consent or approval shall
be required in connection with the transactions contemplated by the Merger
Agreement under any loan or credit agreement, note, mortgage, indenture, lease
or other agreement or instrument, except those for which failure to obtain such
consents and approvals would not, individually or in the aggregate, have a
Material Adverse Effect on Parent or Acquisition or the validity of the Merger;
and (iv) receipt of an opinion of legal counsel to Parent as to the matters set
forth in Exhibit A to the Merger Agreement.
 
     Termination of Merger Agreement and Termination Fees. Either GTI or
Technitrol may terminate the Merger Agreement if: (i) they mutually consent in
writing to terminate the Merger Agreement; (ii) a final order or similar action
by a court of competent jurisdiction in the United States or other United States
Governmental Entity (as defined in the Merger Agreement) restrains, enjoins or
otherwise prohibits the Merger; or (iii) the Merger has not been consummated by
November 30, 1998, unless the terminating party has caused the failure to meet
the closing conditions by failing to fulfill its obligations under the Merger
Agreement.
 
     In addition, Technitrol may terminate the Merger Agreement if: (i) GTI
breaches any of its representations or warranties in the Merger Agreement and
the first or third condition precedent, above, to Technitrol's obligation to
close the Merger is not capable of being satisfied by November 30, 1998; (ii)
GTI breaches a covenant in the Merger Agreement having a Material Adverse Effect
or materially adversely affecting (or materially delaying) the consummation of
the Merger, such that the second or third condition precedent, above, to
Technitrol's obligation to close the Merger is not capable of being satisfied by
November 30, 1998 and such breach has not been cured within twenty business days
after notice thereof by Technitrol; (iii) the Board has recommended to GTI's
stockholders a Superior Proposal (as defined in the Merger Agreement) and GTI's
stockholders have not adopted the Merger Agreement by November 30, 1998; (iv)
the Board has withheld, withdrawn, modified or changed its approval or
recommendation of the Merger Agreement or the Merger and GTI's stockholders have
not adopted the Merger Agreement by November 30, 1998; (v) GTI stockholders
perfecting appraisal rights hold more than 10% of the outstanding shares of
                                       35
<PAGE>   41
 
Common Stock of GTI, assuming for purposes of such calculation the conversion to
shares of Common Stock of all outstanding shares of Preferred Stock; or (vi) the
Board convenes a meeting of GTI stockholders to vote upon the Merger Agreement
and the GTI stockholders fail to adopt the Merger Agreement.
 
     In addition, GTI may terminate the Merger Agreement if: (i) Parent or
Acquisition breaches any of its representations or warranties in the Merger
Agreement and the first or third condition precedent, above, to GTI's obligation
to close the merger is not capable of being satisfied by November 30, 1998; (ii)
Parent or Acquisition breaches a covenant in the Merger Agreement materially
adversely affecting the consummation of the Merger, such that the second or
third condition precedent, above, to GTI's obligation to close the merger is not
capable of being satisfied by November 30, 1998 and such breach has not been
cured within twenty business days after notice thereof by GTI; or (iii) Section
4.4 of the Merger Agreement, relating to the receipt and evaluation by GTI of a
Superior Proposal, is satisfied.
 
     GTI will be required to pay Technitrol a termination fee equal to
Technitrol's actual documented out-of-pocket costs incurred, not to exceed
$750,000, if the Merger is terminated due to: (i) the Board's termination of the
Merger Agreement pursuant to Section 4.4 thereof, relating to the receipt and
evaluation of a Superior Proposal; (ii) the Board's recommendation of a Superior
Proposal and the failure of the Company's stockholders to adopt the Merger
Agreement, instead, by November 30, 1998; (iii) the Board's withholding,
withdrawal, modification or change of its approval or recommendation to GTI's
stockholders of a vote for the adoption of the Merger Agreement, and the failure
of the Company's stockholders to adopt the Merger Agreement, in any event, by
November 30, 1998; or (iv) the Board's convening of a meeting of GTI
stockholders to vote upon the Merger Agreement and the failure of the Company's
stockholders to adopt the Merger Agreement.
 
     In addition, if the Merger Agreement is terminated as a result of one of
the factors enumerated in the preceding paragraph and GTI consummates a
transaction with respect to a Third Party Acquisition Proposal with a party
other than Technitrol or enters into an option, agreement or letter of intent
with respect to a Third Party Acquisition Proposal or other arrangement intended
to transfer control of GTI or the stockholders of GTI tender or grant an option
on shares representing 50% or more of the voting interest in GTI, within twelve
months after termination (and, in the event the Merger was terminated due to a
failure of the Company's stockholders to adopt the Merger Agreement at a meeting
convened by the Board to vote upon the Merger Agreement, a Third Party
Acquisition Proposal was outstanding at the time of such stockholders' meeting),
then GTI will pay to Technitrol an additional termination fee equal to $2
million less the amount paid pursuant to the immediately preceding paragraph.
The termination fee is intended to be the only damages that Technitrol is
entitled to receive if the Merger Agreement is terminated for the first or
second grounds, above, on the basis of which Technitrol can terminate the Merger
Agreement.
 
     Expenses. All expenses incurred in connection with the Merger Agreement and
the transactions contemplated in the Merger Agreement will be paid by the party
incurring such expenses.
 
     Amendment. The parties to the Merger Agreement may modify or amend any
provision of the Merger Agreement at any time prior to the Effective Time,
whether before or after adoption of the Merger Agreement by the GTI
stockholders, by written agreement executed and delivered by duly authorized
officers of the respective parties, but, after such adoption, no amendment shall
be made which requires the approval of GTI stockholders under applicable law
without such approval.
 
ACCOUNTING TREATMENT
 
     The Merger will be accounted for under the purchase method of accounting. A
final determination of required purchase accounting adjustments of the fair
value of the assets and liabilities of GTI has not yet been made.
 
CERTAIN EFFECTS OF THE MERGER
 
     Upon consummation of the Merger, Acquisition will be merged into GTI, the
separate corporate existence of Acquisition will cease, and GTI will continue as
the surviving corporation. Thereafter Technitrol
 
                                       36
<PAGE>   42
 
will own directly or indirectly all of the outstanding shares of Common Stock
and will be entitled to all of the benefits and detriments resulting from that
interest, including all income or losses generated by GTI's operations and any
future increase or decrease in GTI's value. After the Effective Time, the
present holders of Common and Preferred Stock will no longer have any equity
interest in GTI, will not share in the future earnings or growth of GTI and will
no longer have rights to vote on corporate matters. GTI is currently subject to
the information filing requirements of the Exchange Act, and in accordance
therewith, is required to file reports and other information with the Commission
relating to its business, financial statements and other matters. As a result of
the Merger, GTI will become a wholly-owned subsidiary of Parent, there will
cease to be any public market for the Common Stock, and, after the Effective
Time, the Common Stock will be delisted from the Nasdaq National Market. Upon
such event, GTI will apply to the Commission for the deregistration of the
Common Stock under the Exchange Act. The termination of the registration of the
Common Stock under the Exchange Act would make certain provisions of the
Exchange Act (including the proxy solicitation provisions of Section 14(a), and
the short-swing trading provisions of Section 16(b)), no longer applicable to
GTI.
 
             CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
 
     Upon consummation of the Merger each outstanding share of the Common Stock
(except for those with respect to which statutory appraisal rights are perfected
or those owned by Parent or any of its subsidiaries) will be converted into the
right to receive the Merger Consideration.
 
     THE UNITED STATES FEDERAL INCOME TAX CONSEQUENCES SET FORTH BELOW ARE
INCLUDED FOR GENERAL INFORMATIONAL PURPOSES ONLY AND ARE BASED UPON PRESENT LAW.
BECAUSE INDIVIDUAL CIRCUMSTANCES MAY DIFFER, EACH STOCKHOLDER IS URGED TO
CONSULT SUCH STOCKHOLDER'S OWN TAX ADVISOR TO DETERMINE THE APPLICABILITY OF THE
RULES DISCUSSED BELOW TO SUCH STOCKHOLDER AND THE PARTICULAR TAX EFFECTS OF THE
MERGER, INCLUDING THE APPLICATION AND EFFECT OF UNITED STATES ALTERNATIVE
MINIMUM TAX, STATE, LOCAL AND OTHER TAX LAWS.
 
     THE FOLLOWING DISCUSSION DOES NOT ADDRESS TAX CONSEQUENCES TO THE HOLDER OF
THE PREFERRED STOCK, AND MAY NOT BE APPLICABLE TO CERTAIN TYPES OF SHAREHOLDERS,
SUCH AS FINANCIAL INSTITUTIONS, BROKER-DEALERS, SHAREHOLDERS WHO ACQUIRED SHARES
PURSUANT TO THE EXERCISE OF OPTIONS OR OTHERWISE AS COMPENSATION, INDIVIDUALS
WHO ARE NOT CITIZENS OR RESIDENTS OF THE UNITED STATES, FOREIGN ENTITIES AND
PERSONS WHO RECEIVED PAYMENTS IN RESPECT OF OPTIONS OR WARRANTS TO ACQUIRE
COMMON STOCK.
 
     The receipt of cash pursuant to the Merger will be a taxable transaction
for United States federal income tax purposes. In general, for United States
federal income tax purposes, a stockholder will recognize gain or loss equal to
the difference between the cash received by the stockholder pursuant to the
Merger Agreement and the stockholder's adjusted tax basis in the shares of
Common Stock converted into the right to receive the Merger Consideration
pursuant to the Merger Agreement. Such gain or loss will be a capital gain or
loss if the shares of Common Stock constitute capital assets in the hands of the
stockholder. Pursuant to recently enacted legislation, in the case of an
individual holder of Common Stock, any such capital gain generally will be
subject to a maximum United States federal income tax rate of (a) 20% if the
holder's holding period in such shares was more than 18 months at the Effective
Time and (b) 28% if the holder's holding period was more than one year but not
more than 18 months at the Effective Time. Certain limitations apply with
respect to the deductibility of capital losses.
 
     Payments in connection with the Merger may be subject to "backup
withholding" at a 31% rate. Backup withholding generally applies if the
stockholder fails to furnish such stockholder's social security number or other
taxpayer identification number ("TIN"), or furnishes an incorrect TIN. Backup
withholding is not an additional tax but merely a creditable advance payment,
which may be refunded to the extent it results in an overpayment of tax. Certain
persons generally are exempt from backup withholding, including corporations
                                       37
<PAGE>   43
 
and financial institutions. Certain penalties apply for failure to furnish
correct information and for failure to include reportable payments in income.
Stockholders should consult with their own tax advisors as to the qualifications
and procedures for exemption from backup withholding.
 
                             REGULATORY COMPLIANCE
 
     The Merger is subject to review by the Federal Trade Commission and the
Antitrust Division of the Department of Justice under the HSR Act. The Company,
Telemetrix and Technitrol were granted early termination of the HSR waiting
period, effective on June 19, 1998.
 
     A certificate of merger must be filed on behalf of GTI and Acquisition with
the Secretary of State of Delaware in order to effect the Merger.
 
     Except as described above, GTI is not aware of any licenses or regulatory
permits that are material to its business that might be adversely affected by
the Merger, or of any approval or other action by any governmental,
administrative or regulatory agency or authority which would be required prior
to the Effective Time.
 
                                APPRAISAL RIGHTS
 
     If the Merger is consummated, a holder of record of shares of Common Stock
who objects to the terms of the Merger may seek an appraisal under Section 262
of the DGCL of the "fair value" of such holder's shares. The following is a
summary of the principal provisions of Section 262 and does not purport to be a
complete description. A copy of Section 262 is attached to this Proxy Statement
as Appendix C. Failure to take any action required by Section 262 will result in
a termination or waiver of a stockholder's rights under Section 262.
 
     1. A stockholder electing to exercise Appraisal Rights must (a) deliver to
GTI, before GTI stockholders vote on the Merger Agreement, a written demand for
appraisal that is made by or on behalf of the person who is the holder of record
of GTI stock for which appraisal is demanded and (b) not vote in favor of
adopting the Merger Agreement. The demand must be delivered to GTI Corporation
at 9715 Business Park Avenue, San Diego, California 92131, Attention: Bruce C.
Myers, Chief Financial Officer. A proxy or vote against adopting the Merger
Agreement does not constitute a demand. A stockholder electing to take such
action must do so by a separate written demand that reasonably informs GTI of
the identity of the holder of record and of such stockholder's intention to
demand appraisal of such holder's GTI stock. Because a proxy left blank will,
unless revoked, be voted FOR adoption of the Merger Agreement, a stockholder
electing to exercise Appraisal Rights who votes by proxy must not leave the
proxy blank but must vote AGAINST adoption of the Merger Agreement or ABSTAIN
from voting for or against adoption of the Merger Agreement.
 
     2. Only the holder of record of GTI stock is entitled to demand Appraisal
Rights for GTI stock registered in that holder's name. The demand must be
executed by or for the holder of record, fully and correctly, as the holder's
name appears on the holder's stock certificates. If GTI stock is owned of record
in a fiduciary capacity, such as by a trustee, guardian, or custodian, the
demand should be executed in that capacity. If GTI stock is owned of record by
more than one person, as in a joint tenancy or tenancy in common, the demand
should be executed by or for all owners. An authorized agent, including one of
two or more joint owners, may execute the demand for appraisal for a holder of
record; however, the agent must identify the owner or owners of record and
expressly disclose the fact that, in executing the demand, the agent is acting
as agent for the owner or owners of record.
 
     A holder of record, such as a broker, who holds GTI stock as nominee for
beneficial owners may exercise a holder's right of appraisal with respect to GTI
stock held for all or less than all of such beneficial owners. In such case, the
written demand should set forth the number of GTI stock covered by the demand.
Where no number of shares of GTI stock is expressly mentioned, the demand will
be presumed to cover all GTI stock standing in the name of the holder of record.
 
                                       38
<PAGE>   44
 
     3. Within 10 days after the Effective Time, GTI will send notice of the
effectiveness of the Merger to each person who prior to the Effective Time
satisfied the foregoing conditions.
 
     4. Within 120 days after the Effective Time, GTI or any stockholder who has
satisfied the foregoing conditions may file a petition in the Delaware Court of
Chancery demanding a determination of the fair value of the GTI stock.
Stockholders seeking to exercise Appraisal Rights should not assume that GTI
will file a petition to appraise the value of their GTI stock or that GTI will
initiate any negotiations with respect to the "fair value" of such GTI stock.
Accordingly, GTI stockholders should initiate all necessary action to perfect
their Appraisal Rights within the time periods prescribed in Section 262.
 
     5. Within 120 days after the Effective Time, any stockholder who has
complied with the requirements for exercise of Appraisal Rights, as discussed
above, is entitled, upon written request, to receive from GTI a statement
setting forth the aggregate number of shares of GTI stock not voted in favor of
the Merger and with respect to which demands for appraisal have been made and
the aggregate number of holders of such GTI stock. GTI is required to mail such
statement within 10 days after it receives a written request to do so.
 
     6. If a petition for an appraisal is timely filed, after a hearing on the
petition, the Delaware Court of Chancery will determine the stockholders
entitled to Appraisal Rights and will appraise the GTI stock owned by such
stockholders, determining its "fair value" exclusive of any element of value
arising from the accomplishment or expectation of the Merger and will determine
the amount of interest, if any, to be paid upon the value of the GTI stock of
the stockholders entitled to appraisal. Any such judicial determination of the
"fair value" of GTI stock could be based upon considerations other than or in
addition to the price paid in the Merger and the market value of GTI stock,
including asset values, the investment value of the GTI stock and any other
valuation considerations generally accepted in the investment community. The
value so determined for GTI stock could be more, less than, or the same as the
consideration paid pursuant to the Merger Agreement. The Court may also order
that all or a portion of any stockholder's expenses incurred in connection with
an appraisal proceeding, including, without limitation, reasonable attorneys'
fees and fees and expenses of experts utilized in the appraisal proceeding, be
charged pro rata against the value of all GTI stock entitled to appraisal.
 
     7. Any stockholder who has duly demanded an appraisal in compliance with
Section 262 will not, after the Effective Time, be entitled to vote the shares
subject to such demand for any purpose or be entitled to dividends or other
distributions on that GTI stock (other than those payable or deemed to be
payable to stockholders of record as of a date prior to the Effective Time).
 
     8. Holders of GTI stock lose the right to appraisal if no petition for
appraisal is filed within 120 days after the Effective Time, or if a stockholder
delivers to GTI a written withdrawal of such stockholder's demand for an
appraisal and an acceptance of the Merger, except that any such attempt to
withdraw made more than 60 days after the Effective Time requires GTI's written
approval. If Appraisal Rights are not perfected or a demand for Appraisal Rights
is withdrawn, a stockholder will be entitled to receive the consideration
otherwise payable pursuant to the Merger Agreement.
 
     9. If an appraisal proceeding is timely instituted, such proceeding may not
be dismissed as to any stockholder who has perfected a right of appraisal
without the approval of the Delaware Court of Chancery.
 
                     INFORMATION REGARDING GTI CORPORATION
 
GENERAL
 
     GTI Corporation, primarily through its wholly owned subsidiary Valor
Electronics, Inc. (collectively "the Company"), is an international supplier of
magnetics-based, signal management components to original equipment
manufacturers ("OEMs") of local area networks ("LAN"), wide area networks
("WANs"), telecommunications and broadband systems (collectively "networks") for
data and voice communications. In general, the Company's products isolate and
filter the communication signal at the point where two or more network
components are connected to assure that the signal is clean and that the network
and its components are protected.
                                       39
<PAGE>   45
 
PRODUCTS
 
     The Company designs, manufactures, markets, and supports a broad family of
standards-based magnetic components with application-specific interface
solutions for signal management in networking products. These signal management
products provide signal processing and power transfer functions such as circuit
isolation and impedance matching, signal shaping and conditioning, noise
reduction and filtering, and voltage conversion. These electrical functions help
enable the OEM's hardware and software product architecture to transmit data
over the transmission media.
 
     Magnetics-based components are marketed under the Valor name and consist of
two categories, signal processing and power transfer, as more fully described
below. The Company's products comply with the industry standards adopted by the
Institute of Electrical and Electronic Engineers ("IEEE") for the conversion and
transmission of data over copper wire and support the major networking
architectures which have evolved based on these standards.
 
     The Company's magnetic-based components include a broad family of
standards-compliant, miniature, wire-wound transformers; integrated modules; and
subsystem products. The Company works closely with networking customers and
integrated circuit companies to design products that complement the
manufacturers' integrated circuit or chip set configuration with magnetics
applications required to enable the integrated circuit to perform its desired
function. The Company's products are located at most interface points of the
system where signal conversion is required. For example, on the desktop in a LAN
application, these products are found inside the computer on the network
interface adapter card. At the file server, these products are found near the
connection port of hubs or concentrators, routers, and switches, as well as
inside multiple-access units.
 
     Magnetics-based components are an integral part of electronic circuitry. In
LAN applications, circuits need to be isolated from each other, impedances
matched (signal levels stepped up or down), unwanted signals suppressed or noise
emissions filtered, and voltage converted. The LAN topologies that these
networking products support differ in their requirements for transmission speed,
wiring specifications, and signaling-access methods of the LAN; and, as a
result, the component mix, quantity, placement, and degree of component
integration for these products will vary depending upon the LAN topology used.
 
     Signal Processing Products. The majority of the Company's revenues are
derived from signal-processing products which consist of pulse transformers,
chokes, filters, and integrated filter modules. Pulse transformers provide
electrical isolation of circuits and match impedances between different parts of
circuits, thus allowing for different circuits placed within close proximity on
the same board to handle voltage signals without causing data distortion or
circuit damage. In a LAN using copper wire as the transmission medium, isolation
transformers are used on network adapter cards, generally located inside the
computer, close to the connector, to isolate the network wiring from the adapter
card itself. This isolation prevents the network wire from transferring voltage
spikes into the system which would severely damage the circuits. Chokes are used
for filtering and smoothing electrical signals, and are often used in connection
with transformers. In a LAN, the required magnetics application for chokes is
signal conditioning and shaping at the network interface point to suppress
common mode noise (noise present equally on pairs of wires where the signals are
supposed to exist at opposite levels to each other) emission on the transmit and
receive line. The Company's transformers and chokes support Ethernet over
coaxial cable; 10Base-T and Token Ring LAN topologies; 100Base-TX Fast Ethernet,
155 Mbps Asynchronous Transfer Mode ("ATM"), and fibre-channel applications.
Transformers and chokes are also used in telecommunication products with ISDN,
T1/E1/CEPT and xDSL interface applications. Filter products reduce or eliminate
conducted noise frequencies outside of the normal network frequencies from
traveling along transmission media as well as minimize large current or voltage
spikes that would be deemed excessive on the transmission cable. Filter products
are designed to work with the most commonly used integrated circuits and
generally support both transmit or receive functions. Filters are located at the
transmit and receive connection ports in such hardware as adapter cards,
intelligent hubs, routers, and switches and may be placed discretely on
printed-circuit boards or into an integrated filter module.
 
     Integrated filter modules consist of a filter and a transformer and often a
choke in one single module and may also include resistors, compactors and
opto-isolators. Integrated filter modules perform the combined
                                       40
<PAGE>   46
 
functions of signal isolation, impedance matching, signal conditioning,
filtering, noise suppression and overvoltage protection. The Company's filter
products support applications for Ethernet over coaxial cable, 10Base-T, Token
Ring, PCMCIA credit card-sized standard, FDDI over copper, 100Base-VG,
100Base-T4, 155 Mbps ATM, ADSL and Cable Modem.
 
     Beginning in 1998, the Company offers a line of single, one-by-four and
two-by-six integrated connectors which integrate the Company's signal processing
products with RJ45 connectors in a strategic arrangement with AMP (a connector
manufacturer). These integrated connectors offer size and performance benefits
as compared to the current approach of a separate signal processing component
and a separate RJ45 connector.
 
     GTI has been conducting research and development on a technology that, if
successful, might, in some fashion, permit the automation of the production
process of magnetic components of the sort made by the Company and its
competitors while producing components of markedly higher quality at lower cost
than current methods. First (and thus far the only) prototypes were completed in
April 1998, which prototypes do not satisfy the required LAN specifications of
the product. The Company continues to evaluate the design and performance of
these prototypes as well as alternative designs and methodologies. If this
research and development project is ultimately successful and results in a
product that can be manufactured at competitive prices and is acceptable to
customers, this project could have a material positive effect on the business,
financial condition and prospects of the Company. The project is not yet near to
completion, however, and there can be no assurance that the several scientific
and engineering hurdles in the way of successful completion will be overcome. In
addition, there can be no assurance that, even if the technical problems can be
solved, the resulting technology could or would be commercially exploited or
have a material positive effect on the business, financial condition or
prospects of the Company.
 
     Power-Transfer Products. The Company's principal power-transfer products
are DC/DC converters. DC/DC converters take the bus or supply voltage, which
generally operates at a different voltage level than the integrated circuit, and
converts the voltage to a level to enable the integrated circuit to function
optimally. DC/DC converters are also suitable for flash memory and distributed
power applications. In a LAN, DC/DC two watt converters are located in
combination adapter cards and hubs and support Ethernet (10Base2/5) over coaxial
cable applications. 10Base-T topologies do not require a DC/DC converter.
 
CUSTOMERS
 
     The Company's products are sold directly or indirectly to more than 1,000
customers, including primarily OEMs and distributors. Two of these customers
accounted for 18% and 13% of the Company's total sales in 1997. Two customers
accounted for 20% and 10% of the Company's total sales in 1996, and two
customers accounted for 16% and 14% of the Company's total sales in 1995. No
other customer accounted for 10% or more of total sales in these years, but
several other customers contributed more than 5% of the Company's total sales in
these years. The sales percentage from the Company's OEM and distribution
customers has historically fluctuated and may continue to vary in future
periods. Management believes that future sales concentration to these OEM and
distribution customers is likely to continue. The importance of these customers
to the Company, combined with competitive pressures, could result in the
negotiation of lower sales prices for these customers which could adversely
affect the Company's results of operations and financial condition. The loss of
one of these customers would have a material adverse effect on the Company's
results of operations and financial condition.
 
SALES AND MARKETING
 
     The Company's products are sold in North America through 16 manufacturers'
representative organizations employing over 150 sales engineers trained to sell
the Company's products. These products are also offered for sale through two
national and one regional electronics distributors with branches throughout the
United States and Canada. The efforts of the representative organizations are
directed by three regional manager employees, and the efforts of the
distribution organizations are directed by a national distribution manager
employee, all of whom report to a vice president of sales.
 
                                       41
<PAGE>   47
 
     The international sales structure comprises representative and distributor
networks in Europe and the Pacific Rim. There are directors of sales and
marketing in London, England, and Hong Kong who oversee sales in Europe and
Asia, respectively. The Company employs customer service representatives to
process purchase orders and respond to customer inquiries.
 
COMPETITION
 
     The market for magnetics-based components for network applications is
highly competitive. The Company's LAN products have two principal competitors,
Pulse Engineering, Inc., (a subsidiary of Technitrol) and Bel Fuse, Inc. Each of
these competitors offers a broad product line, and each competes with levels of
manufacturing and engineering capabilities at least similar to the Company's. In
addition, numerous foreign-based firms with strong, low cost manufacturing
capabilities offer specific products with capabilities similar to the Company's
product lines. There is no dominant competitor in the telecommunications market
for magnetic components, and competition varies according to location and type
of interface. Among at least 30 competitors in the telecommunications market,
the Company competes most often with Pulse Engineering, Midcom, Vacuumschmelze
and UMEC.
 
     The number of competitors and the characteristics of competition for the
Company's products varies based on the degree of engineering and design related
to each product. Currently, competition is primarily based on engineering
design, quality, availability, and price. Products with very little engineering
requirements or changes in design have more competitors and typically compete on
price. Products with a high degree of engineering design and component
integration have fewer competitors and typically compete on the ability to
provide solutions.
 
     The market for 10Base-T Ethernet and 10Base-2/5 products is becoming
increasingly mature and, as a result, manufacturing companies are entering the
marketplace with standard products and have sought to compete on the basis of
price. The Company has competed in this environment by focusing on higher
degrees of engineering and functionality, product quality, and availability, as
well as the ability to cost re-engineer mature products. See "Product
Development" for a discussion of new product development and emerging
communications markets.
 
MANUFACTURING AND SUPPLIERS
 
     The manufacturing operations for the Company's products are labor
intensive, and primarily involve the winding of magnetic cores; the assembly and
placement of discrete and integrated circuit components onto printed circuit
boards; product encapsulation; testing; quality assurance; and marking of the
final component. The Company conducts its manufacturing in two operations in the
People's Republic of China ("PRC") and one operation in the Philippines. The
activities of these manufacturing operations are coordinated and supported by
the Company's San Diego-based headquarters and, in times of peak production, may
be supplemented by third-party subcontractors in the PRC and in the Philippines.
All of the Company's manufacturing operations in the PRC and the Philippines are
certified pursuant to ISO 9002. The Company has direct product supervision over
the subcontractor operations. The related subcontractor arrangements are
negotiated on a price-per-piece basis, renewable annually, and generally provide
to the Company flexibility to adapt its production schedule in response to
fluctuations in market demand.
 
     The principal materials and fabricated components used in the Company's
products include ferrite cores, coilforms, leadframes, printed circuit boards,
epoxies, discrete and integrated circuit electronic components. The Company
generally uses standard parts and components for its products and, historically,
has been able to obtain adequate supplies from several existing sources.
Currently, pin coilforms, which are used in approximately 30% of filter
products, are manufactured by a sole-sourced supplier. An interruption in the
supply of pin coilforms or the inability of the Company to procure this
component from alternative sources at acceptable prices within a reasonable time
would materially and adversely affect the Company's business, manufacturing
operations, operating results, and financial condition.

PRODUCT DEVELOPMENT
 
     The market for the Company's products is characterized by rapidly changing
technology, frequent new product introduction, and the requirement to conform to
evolving standards for networking data communications architectures. The
Company's ability to develop and introduce new products to the market in a
timely manner or enhancements to existing products is crucial to its future
success.
 
     The Company is developing its magnetics-based products for use in emerging
communications markets, such as Fast Ethernet, GigaBit, FDDI/CDDI, ATM, xDSL,
ISDN and T1/E1 standards. The Company works closely with networking customers
and integrated circuits manufacturers with which the Company's products must
interface and participates as a member in the IEEE and ANSI Standards Committees
and the ADSL Forum. These efforts give the Company early access to new
technologies and new product plans, which the Company believes provide it with
timely information regarding the development of its products. Concurrent
engineering projects with key customers are also becoming an important factor in
developing new products and product enhancements. In 1997, 1996, and 1995, the
Company incurred design engineering and product development costs of $3,166,000,
$3,245,000 and $4,705,000, respectively.
 
FOREIGN OPERATIONS
 
     Substantially all of the Company's manufacturing operations and
approximately 52% of its identifiable assets (excluding goodwill) are located in
the PRC and the Philippines. See also "Manufacturing and Suppliers" and
"Properties." There are risks inherent to these foreign operations, many of
which are beyond the control of the Company. These risks include exposure to the
effects of political and economic instability and significant changes to
existing international treaties, fluctuating currency exchange rates, changes in
tariffs, taxes, duties and imposts, market forces, and changes in foreign laws
as well as difficulties in staffing and managing foreign subsidiaries and
oversight of subcontracting arrangements. Such risks could result in
interruptions of manufacturing operations, capability, or substantial increases
in operating costs which, if prolonged, would have a material, adverse effect on
the Company's profitability and financial condition. For example, if the United
States Government were to eliminate current favorable trade legislation with
China or increase customs duties, it could have a material adverse effect on a
significant portion of the Company's foreign operations.
 
INTERNATIONAL SALES
 
     Sales to customers outside of the United States comprised approximately 46%
of the Company's total sales in 1997, of which approximately 21%, 22%, and 1%
were made to customers in Asia, Europe, and North America (outside the United
States), respectively. Sales to customers outside the United States as a
percentage of total sales were approximately 48% in 1996, and 42% in 1995.
Additional geographic segment financial information is set forth in the Notes to
the Consolidated Financial Statements included elsewhere herein.
 
     The Company has established sales offices in Hong Kong and London, England
to administer its international sales activities. The Company believes that LAN,
telecommunication and broadband systems, which require magnetics-based
components such as those manufactured by the Company, will make further
penetration into international markets, as has been the case in the United
States. Accordingly, the Company expects that international sales will continue
to represent a significant percentage of total future sales. International sales
are, however, subject to inherent risks, including changes in regulatory
requirements, fluctuating currency exchange rates, increases in tariff and other
barriers, difficulties in obtaining export licenses, and potentially adverse tax
consequences.
 
PROPERTIES
 
     The Company's world-wide headquarters as well as the principal executive,
marketing, sales, product development, manufacturing process design, materials
procurement, managerial and manufacturing support are located in two leased
buildings in San Diego, California. The manufacturing operations for the Company
are located in two leased facilities in the PRC and one leased facility in the
Philippines.

(1) The PRC facilities are operated directly by the Company under negotiated
    contracts between the Company and the provincial government of China. In
    addition to the manufacturing space indicated, each facility includes space
    for staff quarters and dormitories. Such living quarters in the aggregate
    represent 278,500 square feet of space.
 
     In addition to its manufacturing and distribution facilities, the Company
leases small sales offices elsewhere in the United States and the United
Kingdom. The Company believes that its facilities are well maintained, in good
operating condition and adequate to support anticipated operating needs over the
next twelve months.
 
LEGAL PROCEEDINGS
 
     In December 1995, a class-action lawsuit was filed in the United States
District Court, Southern District of California, against the Company and certain
of its officers and directors alleging violations of the Securities Exchange Act
of 1934. In November 1996, the court approved a Stipulation of Settlement with
prejudice resulting in a release of all claims. The settlement amount, paid by
the Company in 1996, was $400,000.
 
     The Company is subject to various federal, state, and local environmental
protection laws and regulations and, from time to time, has incurred costs for
environmental compliance, none of which to date has been material. The Company
has been studying and undertaking certain remedial actions with respect to
groundwater pollution and soil contamination conditions at its closed facility
in Leesburg, Indiana. The Company anticipates that additional environmental
expenses will be incurred in future years as the Company continues its
environmental studies and analysis and, upon mutual agreement with the relevant
state agency, as the Company implements a remediation plan. Based on current
knowledge, the Company does not believe that any future expenses associated with
environmental remediation will have a material impact on the financial position
or results of operations of the Company.
 
     The Company is involved in various legal proceedings and claims arising in
the ordinary course of business, none of which, in the opinion of management, is
expected to have a material effect on the Company's consolidated financial
position or results of operations.

        MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                             RESULTS OF OPERATIONS.
 
     The following discussion should be read in conjunction with the Interim
Unaudited Financial Statements and Notes thereto and the Annual Audited
Financial Statements and Notes thereto included elsewhere in this document.
Amounts are expressed in thousands (except per share data).
 
RESULTS OF OPERATIONS
 
  Three months ended March 28, 1998 compared to the three months ended March 29,
1997
 
     Revenues declined by $8,391 or 37.5% to $14,002 in the first quarter ended
March 28, 1998 from $22,393 in the comparable quarter in 1997. This decrease
resulted from an approximate 31.9% decrease in average selling prices (including
the effects of changes in mix), coupled with an approximate 8.2% decrease in
unit volume. Management attributes the decrease in average selling prices to the
competitive pressures caused by downward pressures on prices in the market for
networking products for which the Company provides components. The decrease in
average selling prices also resulted from a greater current-quarter mix of
lower-priced components for telecommunications markets. The 8.2% decrease in
unit volume generally resulted from softness in the overall market for local
area networking products coupled with the negative effects of customer
uncertainty related to the Company's previously announced consideration of
strategic alternatives (see also Trends, Uncertainties and Prospective
Information included elsewhere herein). The Company expects the declining trend
in revenues to continue through at least the second quarter of 1998.
 
     In the quarter ended March 28, 1998, two of the Company's customers
individually accounted for more than 10% of the Company's sales, and
collectively these two customers accounted for 41.4% of total 1998 first quarter
sales. In the comparable quarter of the prior year, two of the Company's
customers, each individually accounting for more than 10% of the Company's
sales, collectively accounted for 28.7% of total sales. The sales percentage
from the Company's OEM customers has historically fluctuated and will likely
continue to fluctuate in future periods. The importance of these customers to
the Company, combined with competitive pressures, could result in the
negotiation of lower sales prices for these customers which could adversely
effect the Company's results of operations and financial condition. The loss of
one of these customers would have a material adverse affect on the Company's
results of operations and financial condition.
 
     The Company's backlog at March 28, 1998, was approximately $8,600 compared
to approximately $17,500 at March 29, 1997. The Company's backlog at the
beginning of each quarterly period is not sufficient to achieve anticipated
revenues for the quarter. As a result, the Company's sales for any quarter are
dependent upon obtaining "turns business" (i.e., orders received in a quarter
for shipment within the same quarter). Further, current trends are towards a
greater dependence on turns business as the Company's customers demand shorter
lead times and provide fewer long-term orders. Management expects this trend to
continue. If turns orders do not materialize, the Company's operating results
will be adversely affected. The Company's future performance on a
quarter-to-quarter and year-to-year basis will be materially affected by the
volume, mix and timing of orders received.
 
     Cost of sales decreased $2,845 or 17.2% from $16,509 (73.7% of revenue) in
the first quarter of 1997 to $13,664 (97.6% of revenue) in the first quarter of
1998. The current quarter cost of sales include a $1,500 charge related to the
consolidation of the Company's two PRC factories into one factory. The decrease
in cost of sales of $2,845 results from decreased variable costs related to
decreased sales, and from a 26.5% reduction in overhead spending, offset
somewhat by the factory consolidation costs and by the negative effects of sales
price erosion. The increase in cost of sales as a percent of revenue results
from the factory consolidation costs, from the sales price erosion, and from the
effects of fixed costs spread over the lower volume, offset somewhat by the
decreased overhead spending.
 
     Gross profit decreased $5,546 or 94.3% from $5,884 in the first quarter of
1997 to $338 in the first quarter in 1998. Gross profit as a percent of sales
decreased from 26.3% to 2.4%. The decrease in gross profit as a percent of sales
results from the factory consolidation costs, from the sales price erosion, and
from the effects of fixed costs spread over the lower volume, offset somewhat by
the decreased overhead spending.
 
                                       46
<PAGE>   52
 
     Operating expenses for the first quarter of 1998 decreased by $635 or by
11.6% from $5,476 (24.5% of sales) in the first quarter of 1997 to $4,841 (34.6%
of sales) in the first quarter of 1998. The decrease in operating expenses of
$635 relates primarily to decreased commissions resulting from the decreased
sales. The increase in operating expenses as a percent of revenues is a function
of sales, marketing, administration and product development costs that did not
decline in proportion to the decline in sales.
 
     Other expenses for the first quarter of 1998 decreased $37 from $120 in the
comparable quarter of the prior year to $83 in the current quarter. This
decrease is primarily due to decreased interest expense associated with
decreased borrowings.
 
     The Company's tax provision was zero for the first quarter of 1998 compared
to $100 for the comparable quarter of the prior year. The current quarter
provision is disproportionate to the related loss from operations because of
potential uncertainties related to the realization of the Company's net
operating loss and capital-loss carryforwards.
 
     The significant decrease in gross profit offset slightly by the decreases
in operating expenses and other expenses resulted in a loss from operations for
the first quarter of 1998 of $4,586 or $0.52 per share. This compares to income
from operations of $188 or $0.01 per share in the comparable quarter of the
prior year. Including the cumulative effect of change in accounting principle in
the first quarter of 1998 of $899, the first quarter of 1998 net loss was $5,485
or $0.62 per share. This compares to net income of $188 or $0.01 per share in
the comparable quarter of the prior year.
 
  1997 compared to 1996
 
     Revenues declined by 10.7% from $92,533 in 1996 to $82,591 in 1997. This
decrease resulted from an approximate 17.0% decrease in average selling prices
(including the effects of changes in mix), offset somewhat by an approximate
4.7% increase in unit volume. Management attributes the decrease in average
selling prices to the competitive pressures caused by downward pressures on
prices in the market for networking products for which the Company provides
components. The decrease in average selling prices also resulted from a greater
current year mix of lower-priced components for telecommunications markets. The
4.7% increase in unit volume resulted primarily from initial successes in the
telecommunications markets as a result of the Company's strategy to build on its
LAN magnetics expertise and to penetrate new telecommunications and broadband
markets.
 
     Two of the Company's OEM customers collectively accounted for 31% and 30%
of the Company's sales in the current and prior year, respectively. The sales
percentage from the Company's OEM customers has historically fluctuated and may
continue to vary in future periods. Management believes that future sales
concentration to these customers is likely to continue. The importance of these
customers to the Company, combined with competitive pressures, could result in
the negotiation of lower sales prices for these customers which could adversely
effect the Company's results of operations and financial condition. The loss of
one of these customers would have a material adverse affect on the Company's
results of operations and financial condition.
 
     Cost of sales decreased $12,186 or 16.2% from $75,350 (81.4% of revenue) in
1996 to $63,164 (76.5% of revenue) in 1997. Gross profit increased $2,244 or
13.1% from $17,183 in 1996 to $19,427 in 1997. Gross profit as a percent of
sales increased from 18.6% to 23.5% in 1996 and 1997, respectively. These
improved margins resulted primarily from decreased labor and overhead costs
resulting from the 1996 replacement of China subcontract labor with direct
employees and facilities which more than offset the decreased sales prices.
Nevertheless, based on the Company's current overhead structure, if future
volumes decline, the actual cost per unit and gross profit could be materially
and adversely affected.
 
     Operating expenses for 1997 decreased by $3,980 or 15.5% from $25,722
(27.8% of sales) in 1996 to $21,742 (26.3% of sales) in 1997. The prior year
included a $1,900 charge related to the restructuring of the Company's Asia
operations, a $650 charge related to the settlement and legal costs of a class
action lawsuit, and an $871 charge related to employee severance. Absent these
prior-year costs, operating expenses
 
                                       47
<PAGE>   53
 
decreased $559 or 2.5% primarily as a result of decreased professional fees and
decreased administrative personnel, offset somewhat by increased sales and
marketing expenditures.
 
     Other expenses increased $656 from $162 in 1996 to $818 in 1997 primarily
because of a $499 net loss on the liquidation of the VideoServer shares received
in connection with the Promptus divestiture.
 
     The Company's tax provision (benefit) related to continuing operations was
$0 in 1997 compared to a $1,050 benefit in 1996. These tax amounts are
disproportionate to the related loss from continuing operations because the
Company's net operating loss carryforwards have been used to decrease the amount
of the permanently reinvested off-shore earnings that had not been taxed in
prior years.
 
     The increase in gross profit and the decreases in operating expenses,
offset somewhat by the increase in other expenses and the decrease in tax
benefits, resulted in a loss from continuing operations in 1997 of $3,133 or
$0.38 per share. This compares to a loss from continuing operations of $7,651 or
$0.88 per share in 1996. Including the effects of discontinued operations in
1996, the net loss decreased $18,338 from $21,471 or $2.42 per share in the
prior year to $3,133 or $0.38 per share in 1997.
 
  1996 compared to 1995
 
     Revenues declined by 19.4%, from $114,836 in 1995 to $92,533 in 1996. This
decrease consisted of an approximate 5.3% decrease in average selling prices and
an approximate 14.9% decrease in unit volume. Management attributes the decrease
in average selling prices to the competitive pressures caused by downward
pressures on prices in the market for networking products for which the Company
provides components. The decrease in unit volume is attributed to certain
product quality issues that management believes have since been addressed.
 
     Cost of sales decreased by 8.9%, from $82,729 in 1995 to $75,350 in 1996.
This decrease was due primarily to the decline in unit sales volume and the
factors discussed below related to gross margin.
 
     Gross margin decreased by 46.5%, from $32,107 in 1995 to $17,183 in 1996.
Gross margin as a percent of revenue decreased by 33.6%, from 28% in 1995 to
18.6% in 1996. The decline in gross margin resulted primarily from the decline
in unit volume and from increased excess and obsolete inventory provisions in
1996. The decrease in gross margin as a percent of revenues resulted primarily
from the effects of fixed costs spread over lesser volume and from the price
decline described above. This decrease was off set slightly by decreased labor
and overhead costs resulting from the May 1996 formation of the Company's
wholly-owned manufacturing operation in China, from the resultant termination of
subcontract processing arrangements in China, and from the resultant
restructuring of the Company's Hong Kong management team.
 
     Operating expenses increased by 1.3%, from $25,382 in 1995 to $25,722 in
1996. The 1996 operating expenses included a $1,900 charge related to the
restructuring of the Company's off-shore operations, particularly in Hong Kong,
a $650 charge related to the settlement and legal costs of a class action
lawsuit, and a $871 charge related to employee severance. The 1995 operating
expenses included a $1,376 charge related to severance. Absent these charges in
1996 and 1995, operating expenses decreased by 5.6% resulting primarily from
reductions in commissions expense and personnel.
 
     Other expenses increased from $29 in 1995 to $162 in 1996 primarily as a
result of gains on the sale of certain fixed assets in 1995.
 
     The Company's tax provision (benefit) related to continuing operations
changed from an expense of $506 in 1995 to a net benefit of $1,050 in 1996. The
net tax benefit in 1996 resulted primarily from the carryback of the U.S.
portion of the 1996 consolidated loss. The 1995 expense is significantly less
than a provision based on the U.S. Federal tax rate due to off-shore tax
holidays and due to the Company's intentions (at that time) to not repatriate
off-shore earnings.
 
     The decreased revenue levels, decreased gross margin and increased
operating expenses, off-set somewhat by income tax consequences, resulted in a
loss from continuing operations after taxes of $7,651 ($0.88 per share) in 1996.
This compares to income from continuing operations after taxes of $6,124 ($0.56
per share on a diluted basis) in 1995.
                                       48

     The Company discontinued three operations during the years 1995 and 1996.
Losses from discontinued operations were $2,998 ($.33 per share) in 1996
compared to $2,178 ($.20 per share on a diluted basis) in 1995. Estimated loss
on disposal of discontinued operations was $10,822 ($1.21 per share) in 1996 and
$2,000 ($.18 per share on a diluted basis) in 1995. Including the effect of
discontinued operations, the net loss was $21,471 ($2.42 per share) in 1996
compared to net income of $1,946 ($.18 per share on a diluted basis) in 1995.
 
TRENDS, UNCERTAINTIES AND PROSPECTIVE INFORMATION
 
     The Company expects that revenues in its second quarter of 1998 will again
decline significantly, both on a sequential quarter and on a comparable-quarter
basis. Management believes that this continuing revenue decline results first
from an overall softening in demand for computer and networking products, from
adverse economic conditions in Asia, and from intensified competition and
resultant price declines in the LAN market. These adverse factors have been
further exacerbated by the uncertainty caused by the Company's previously
announced consideration of strategic alternatives, which announcement has caused
reluctance on the part of certain customers to place orders and to engage in new
design activities with the Company, at least until such time as the
consideration of strategic alternatives is finalized. Also in response to these
adverse trends and for other reasons, the Company continues to initiate ongoing
revenue enhancement and cost reduction programs. However, there can be no
assurance that revenues will increase, nor can there be any assurance that the
Company will be able to reduce costs in an amount sufficient to offset the
negative effects of the revenue decline.
 
     Management believes that its future operating results will be influenced by
a number of factors including, but not limited to: general economic conditions;
the growth of the LAN and internetworking markets; the growth of broadband,
global services and high-speed, digital, network and telecommunications
applications; timely new product introductions; dependence on key OEM customers;
market acceptance of new networking, telecommunications and broadband
technologies; market acceptance of the Company's products; and numerous
competitive forces. It is anticipated that the Company's operating results in
the foreseeable future will remain dependent on the success of the Company to
identify, develop, manufacture, and market new products or to enhance existing
product offerings
 
     The majority of the Company's sales continue to be derived from products
that support Ethernet applications. The Company's operating results could be
affected if there is an unexpected change in such technologies or if the Company
does not respond appropriately to expected changes. The Company supplies OEM's
with product compliant with all relevant IEEE, ANSI, and ATM forum standards for
100Base-TX Fast Ethernet, TP/PMD (FDDI over copper), xDSL, and 155 Mbps ATM
applications. The success of these advanced products is dependent on many
factors, such as the Company's ability to manufacture these products in
sufficient quantities to meet anticipated demand and the overall market
acceptance of these new technologies. The inability of these advanced networking
products to gain market acceptance or potential delays of the widespread
installation of such products could subject the Company's existing products to
increased competition and pricing pressures, which would adversely affect the
Company's operating results.
 
     The Company's future performance will also be affected by the volume, mix
and timing of orders received during a particular period. There can be no
assurance that orders from existing customers will continue at the levels of
previous years or that the Company will be able to obtain orders from new
customers. If anticipated orders do not develop, or changes in delivery
schedules or cancellation of orders occur, the Company's per-unit manufacturing
costs, expenditures, and inventory levels could be disproportionately high in
relation to sales. This could have an adverse effect on the Company's operating
results and liquidity for that quarterly period.
 
     The Company's results and stock price have been, and may continue to be,
subject to significant volatility, particularly on a quarterly basis. A further
reduction in sales or increase in operating losses could have an immediate and
significant adverse affect on the trading price of the Company's Common Stock in
any given quarterly period.
 
     Throughout the world, many existing computer programs use only two digits
to identify a year in the date field. These programs were designed and developed
without considering the impact of the upcoming change in
                                       49
<PAGE>   55
 
the century. If not corrected, many computer applications could fail or create
erroneous results by or at the Year 2000. The Year 2000 issue affects virtually
all companies and organizations. During 1997, the Company completed a migration
of its information systems (for all functions of the Company) to new Enterprise
Resource Planning software (database and applications software) which fully
addresses the Year 2000 issue. Also, the Company's management has reviewed and
evaluated the potential impact of the Year 2000 issue on other application
software, firmware and hardware utilized by the Company and have concluded that
the Company has no additional or significant exposure (from an operational or a
financial perspective) related to this matter.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     For the quarter ended March 28, 1998, the Company satisfied its working
capital and capital expenditure requirements primarily through reductions to
inventory and accounts receivable levels. The Company's primary uses of these
available funds was to fund operating losses, to add equipment, and to reduce
current liabilities. For the year ended December 31, 1997, the Company satisfied
its working capital and capital expenditure requirements through net borrowings
from a related party, the proceeds from the disposal of Promptus, income tax
refunds and internally generated cash from operations (net income before
depreciation and amortization). The Company's primary uses of these available
funds was to add equipment, to increase inventories and to reduce current
liabilities. These sources and uses of cash are detailed in the Consolidated
Statements of Cash Flows included elsewhere in this document.
 
     In September 1997, the Company received a $3.5 million Federal tax refund
resulting from the carryback of the 1996 U.S. operating loss and 1995 U.S.
capital loss to prior profitable periods. The Company is now in a Federal tax
loss carryforward position, and no further Federal tax refunds are available. As
of March 28, 1998, the Company has foreign tax refunds receivable totaling
$2,878 which the Company expects to collect in 1998. The Company's 1994 Federal
tax return is currently under audit, and the 1997 and prior years' Federal,
state and foreign tax returns are subject to audit. Such audits could result in
adjustments to the Company's tax position.
 
     In February 1997, the Company obtained a $2,500 two-year term note from its
majority shareholder as more fully described in the Notes to Consolidated
Financial Statements included elsewhere in this document. The first payment on
this note of $625 plus interest was paid in August 1997, and the second payment
of $625 plus interest was paid in February 1998.
 
     In April 1997, the Company completed the divestiture of its interest in
Promptus Communications, Inc. The Company received approximately $8.2 million in
cash, net of transaction costs, and 157,795 shares of VideoServer (Nasdaq: VSVR)
common stock. As of December 31, 1997 the Company had sold all of these shares
of VideoServer for total proceeds of approximately $1.8 million.
 
     In the first quarter of 1998, the Company purchased capital equipment
totaling $509. These expenditures were primarily for production equipment. In
1997, the Company purchased capital equipment approximating $3.7 million. These
expenditures were primarily for production equipment and information systems.
The Company anticipates that capital expenditures will total about $3 to $5
million per year for the foreseeable future, depending on revenue growth rates,
if any. These capital expenditures are anticipated to be primarily for
automation equipment to further improve quality, increase capacity and increase
manufacturing labor efficiency. The Company's capital expenditure estimates
assume that future additional capacity needs, if any, are realized through
expansion in subcontractor relationships, requiring a relatively low level of
facility expenditures. The Company anticipates that most of its capital
expenditures for the foreseeable future will be funded through cash on hand or
cash generated from operations.
 
     Management believes that funds on hand will be sufficient to finance
working capital needs, projected capital-expenditure requirements and debt
maturities at least through the next twelve months assuming that revenues and
costs achieve anticipated levels. However, if revenue levels are lower than
anticipated (see also Trends, Uncertainties and Prospective Information included
elsewhere herein), and if the Company's cost
 
                                       50
<PAGE>   56
 
reduction efforts are not successful, then the Company may be forced to seek
additional financing. There can be no assurance that additional financing will
be available in amounts or at terms acceptable to the Company.

                     (IN THOUSANDS, EXCEPT PER SHARE DATA)
 
NOTE 1: BASIS OF PRESENTATION
 
     The accompanying unaudited condensed consolidated financial statements
reflect the accounts of GTI Corporation (the "Company"), together with its
majority-owned subsidiaries. All significant intercompany transactions and
balances have been eliminated.
 
     These unaudited condensed consolidated financial statements have been
prepared pursuant to the rules and regulations of the Securities and Exchange
Commission. Certain information and disclosures normally included in annual
financial statements prepared in accordance with generally accepted accounting
principles have been condensed or omitted pursuant to those rules and
regulations, although the Company believes that the disclosures made are
adequate to prevent the information from being misleading. These unaudited
condensed consolidated financial statements reflect, in the opinion of
management, all adjustments (which include only normal recurring adjustments)
necessary to fairly present the results of operations and financial position as
of the dates and for the periods presented. These unaudited condensed
consolidated financial statements should be read in conjunction with the audited
financial statements and related notes included in the Company's Form 10-K/A
filed with the Securities and Exchange Commission for the year ended December
31, 1997 and attached hereto as pages F-8 through F-26. The results for the
interim periods presented are not necessarily indicative of results to be
expected for a full year.
 
     Certain prior-year amounts have been reclassified to conform to
current-year presentation.

NOTE 4: PLANT CLOSURE
 
     In the quarter ended March 28, 1998, the Company decided to combine its two
factories in the People's Republic of China ("PRC") into one factory in the PRC.
Costs associated with the plant closure of $1,500 consist primarily of the
impairment of fixed assets which are now surplus to the operations of the
remaining PRC factory. These costs are included in cost of sales in the current
quarter.

NOTE 5: CUMULATIVE EFFECT FROM CHANGE IN ACCOUNTING PRINCIPLE
 
     In the quarter ended March 28, 1998, the Company implemented Statement of
Position 98-5, "Reporting on the Costs of Start-Up Activities" ("SOP 98-5"),
which requires organization costs to be expensed as incurred. Accordingly, in
the current quarter, the Company recorded a charge of $899 as a cumulative
effect from change in accounting principle for costs originally related to the
organization of the Company's operations in the PRC.

Standards No. 130 "Reporting Comprehensive Income," which requires companies to
report all changes in equity during a period, except those resulting from
investment by owners and distribution to owners. The components for
comprehensive income are as follows:

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Stockholders and Board of Directors
GTI Corporation:
 
     We have audited the accompanying consolidated balance sheets of GTI
Corporation (a Delaware corporation) and subsidiaries as of December 31, 1997
and 1996, and the related consolidated statements of operations, stockholders'
equity and cash flows for each of the three years in the period ended December
31, 1997. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of GTI
Corporation and subsidiaries as of December 31, 1997 and 1996, and the results
of their operations and their cash flows for each of the three years in the
period ended December 31, 1997 in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                   (DOLLARS IN THOUSANDS, EXCEPT SHARE DATA)
 
NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Principles of Consolidation -- The consolidated financial statements
include the accounts of GTI Corporation and its majority-owned subsidiaries
(collectively the Company). All significant intercompany transactions and
balances have been eliminated.
 
     Financial Statement Preparation -- The preparation of financial statements
in conformity with generally accepted accounting principles requires management
to make estimates and assumptions. These estimates and assumptions affect the
reported amounts of assets, liabilities, revenues and expenses, and disclosure
of contingent assets and liabilities. Actual results could differ from
management's estimates.
 
     Cash Equivalents -- Cash equivalents consist of short-term, highly liquid
investments purchased with a maturity date of three months or less. Cash
equivalents are stated at cost, which approximates market value.
 
     Concentration of Credit Risk and Geographic Operations -- The Company
invests a portion of its excess cash in debt instruments of financial
institutions with strong credit ratings and has established guidelines relative
to diversification and maturities that maintain safety and liquidity. The
Company has not experienced any significant losses on its cash equivalents. The
Company sells its products to customers in diversified industries worldwide. The
Company performs ongoing credit evaluations of its customers' financial
condition and maintains allowances for potential credit losses. Actual losses
have been within management's expectations. As of December 31, 1997, two large
customers represented approximately 46% of the Company's net accounts receivable
balance. A significant portion of the Company's manufacturing operations and its
inventories are concentrated in the People's Republic of China (the "PRC") and,
to a lesser extent, the Philippines.
 
     Inventories -- Inventories are stated at the lower of cost (first-in,
first-out) or market and include direct labor, materials, and manufacturing
overhead.
 
     Property, Plant, and Equipment -- Property, plant, and equipment are stated
at cost less accumulated depreciation. Depreciation is computed using the
straight-line method over estimated useful lives of 7 to 25 years for buildings
and improvements and 3 to 7 years for machinery, equipment, furniture, and
fixtures. Expenditures for property additions together with major renewals and
improvements are capitalized. Maintenance, repairs, and minor renewals and
betterments are charged to expense.
 
     Excess of Cost over Net Assets of Acquired Companies -- The excess of
acquisition cost over the fair value of net assets (goodwill) of Valor
Electronics, Inc. ("Valor," the Company's primary operating subsidiary) is being
amortized using the straight-line method over 35 years. The Company periodically
re-evaluates the original assumptions and rationale utilized in the
establishment of the carrying value and estimated life of this asset. Management
believes that there has been no impairment of the goodwill as reflected in the
Company's consolidated financial statements as of December 31, 1997. The Company
is subject to technological changes, which could cause management to reassess
its estimate of the realizability of goodwill and/or its amortization period.
The determinants used for this evaluation include management's estimate of the
asset's continuing ability to generate positive income from operations and
positive cash flow in future periods as well as the strategic significance of
the intangible asset to the Company's business objectives. Cost in excess of net
assets of Valor, net of amortization, was $19,149 and $19,845 as of December 31,
1997 and 1996, respectively.
 
     Income Taxes -- The Company accounts for income taxes under Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes." This
statement requires an asset and liability approach to account for income taxes.
The Company provides deferred income taxes for temporary differences that will
result in taxable or deductible amounts in future years based on the reporting
of certain costs in different periods for financial statement and income tax
purposes.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                   (DOLLARS IN THOUSANDS, EXCEPT SHARE DATA)
 
     Foreign Currency Translation -- Assets and liabilities of the Company's
foreign operations are translated into U.S. dollars at the exchange rate in
effect at the balance sheet date, and revenue and expenses are translated at the
average exchange rate for the period. Translation gains or losses of the
Company's foreign subsidiaries are not included in net income but are reported
as a separate component of stockholders' equity. The functional currency of
those subsidiaries is the primary currency in which the subsidiary operates.
Gains and losses on transactions in denominations other than the functional
currency of the Company's foreign operations, while not material in amount, are
included in the results of operations. Most of the Company's worldwide sales and
inventory and equipment purchases are denominated in U.S. dollars, and most of
the Company's cash is invested in U.S. dollars. As a result, the Company
typically does not enter into foreign exchange transactions to hedge balance
sheet and intercompany balances against movements in foreign exchange rates.
 
     Net Income (Loss) Per Share of Common Stock -- In 1997 the Company adopted
Statement of Financial Accounting Standards No. 128 ("SFAS 128"), "Earnings Per
Share," which sets forth the basis for the computation of "basic" earnings per
share and "dilutive" earnings per share. Basic EPS excludes dilution and is
computed by dividing income (loss) available to common stockholders by the
weighted-average number of common shares outstanding for the period. Diluted EPS
reflects the potential dilution that could occur if securities or other
contracts to issue common stock were exercised or converted into common stock or
resulted in the issuance of common stock that would then share in the earnings
of the entity. Diluted EPS is computed on the basis of the weighted average
shares of Common Stock outstanding plus common equivalent shares arising from
the effect of cumulative convertible Preferred Stock, using the if-converted
method, and dilutive stock options, using the treasury-stock method. All EPS
amounts for prior years and quarters have been restated to conform to these new
standards, and the effect of the restatement was not significant.
 
     Recent Accounting Pronouncements -- In 1997, the Financial Accounting
Standards Board issued Statements No. 130 ("SFAS 130"), "Reporting Comprehensive
Income" and No. 131 ("SFAS 131"), "Disclosures about Segments of an Enterprise
and Related Information." SFAS 130 requires that all items that are required to
be recognized under accounting standards as components of comprehensive income
be reported in a financial statement that is displayed with the same prominence
as other financial statements. The statement requires that an enterprise
classify items of other comprehensive income by their nature in a financial
statement and to display the accumulated balance of other comprehensive income
separately from retained earnings and additional paid-in capital in the equity
section of a statement of financial position. SFAS 131 establishes standards for
the way public business enterprises report information about operating segments
in annual financial statements and requires that those enterprises report
selected information about operating segments in interim financial statements.
Both SFAS 130 and 131 are effective for fiscal years beginning after December
15, 1997.
 
NOTE 2: BUSINESS COMBINATION AND DISCONTINUED OPERATIONS
 
     Promptus -- In January 1995, the Company completed the acquisition of
approximately 72% of the issued and outstanding capital stock of Promptus for
approximately $19.1 million in cash, net of cash acquired. The acquisition was
accounted for as a purchase and, accordingly, the purchase price was allocated
to the assets acquired and liabilities assumed based on their estimated
fair-market value. This allocation resulted in approximately $17.2 million of
costs in excess of the net assets acquired, which was being amortized over 20
years.
 
     In March 1997, Promptus entered into an agreement (the "NAC Transaction")
to sell the net assets of its Network Access Card business ("NAC") for
approximately $20,000, consisting of $14,500 in cash and 223,881 shares of
VideoServer, Inc. Immediately after the closing of the NAC transaction, Promptus
purchased 100% of the Promptus shares held by the Company and repaid certain
indebtedness to the

                   (DOLLARS IN THOUSANDS, EXCEPT SHARE DATA)
 
Company for an aggregate of approximately $11,600, net of certain transaction
costs. The net proceeds to the Company at closing were $8,200 in cash and
approximately 158,000 shares of common stock of VideoServer, Inc. resulting in a
loss on disposal of approximately $10,800. As a result of this divestiture, the
operations prior to closing and the loss on disposal of Promptus are included
within discontinued operations. In 1997, the Company incurred an additional $499
loss resulting from the decline in value of VideoServer from the date of closing
to the date the Company was able to liquidate the VideoServer shares. This $499
loss was recorded in 1997 in continuing operations.
 
     E-Group -- In December 1995, the Company completed the divestiture of
certain assets and liabilities of the E-Group for approximately $12,500,
resulting in a gain of approximately $3,000, net of income taxes of $2,500. The
Company received $11,750 in cash paid at the closing, $250 in escrow funds, and
a $500 promissory note due in three years. The escrow funds will remain in
escrow until June 1997, at which time, if no purchase price adjustment occurs,
all escrow funds will be remitted to the Company.
 
     Esco -- In February 1996, the Company sold 100% of Esco's common stock in
exchange for approximately $4,100, consisting of $2,200 in cash and a $1,900
promissory note due in equal installments over six years, resulting in a loss on
disposal of approximately $5,000, net of income tax benefits of approximately
$1,300. This loss was accrued in 1995.
 
     The sales of the E-Group, Esco and Promptus were made pursuant to formal
divestiture plans adopted by the Company's Board of Directors which required the
plans to be carried out within one year. Accordingly, these businesses have been
accounted as discontinued operations in accordance with Accounting Principles
Board Opinion No. 30.
 
     The operating results of the discontinued operations during the period of
the Company's ownership are summarized as follows:

NOTE 5: CREDIT AGREEMENTS AND RELATED-PARTY NOTE
 
     Through December 1997 the Company had a line of credit agreement with a
bank. Interest on outstanding borrowings accrued at prime plus one and one
quarter percent, and the line was secured by substantially all the Company's
domestic assets. The line of credit agreement expired in December 1997, and as
of December 31, 1997 and 1996, there were zero and $4.9 million, respectively,
outstanding under this arrangement.
 
     In February 1998, the Company negotiated a new line of credit, subject to
activation. However, based on recent financial performance (see Note 13), it is
unlikely that this line will be activated.
 
     In February 1997, the Company entered into a Note Purchase Agreement (the
"Note") with Telemetrix PLC ("Telemetrix," the Company's majority shareholder).
By the terms of the Note, Telemetrix loaned $2,500 to the Company with principal
to be repaid in four equal semi-annual installments of $625,000 (plus applicable
interest) beginning August 1997 and ending February 1999. Interest accrues at
Prime plus 4% (12.5% as of December 31, 1997). The loan is secured by a
subordinated security interest in all of the Company's assets. As of December
31, 1997, the outstanding balance on this Note was $1,875. Also, by the terms of
the Note and related agreements, the Company granted Telemetrix a warrant to
acquire 250,000 shares of GTI common stock at an exercise price of $6 per share.
The warrant expires 30 days after the Note is repaid in full.

     Income tax provision is not recorded for US Federal income taxes on a
portion of the undistributed earnings of foreign subsidiaries as such earnings
are intended to be permanently reinvested in those operations. Such earnings
would become taxable upon the sale or liquidation of these foreign subsidiaries
or upon the remittance of dividends. Accumulated undistributed earnings of
foreign subsidiaries on which US taxes have not been provided are approximately
$37,300, which would result in a related tax liability of $9,300, net of
estimated foreign tax credits of $6,700, if such earnings were repatriated.

     Rental expense amounted to $3,468, $2,879 and $3,280 in the years ended
December 31, 1997, 1996 and 1995, respectively.
 
     Litigation: In December 1995, a class-action lawsuit was filed in the
United States District Court, Southern District of California, against the
Company and certain of its officers and directors alleging violations of the
Securities Exchange Act of 1934. In November 1996, the court approved a
Stipulation of Settlement with prejudice resulting in a release of all claims.
The settlement amount, paid by the Company in 1996, was $400.
 
     The Company is involved in various legal proceedings and claims arising in
the ordinary course of business, none of which, in the opinion of management, is
expected to have a material effect on the Company's consolidated financial
position or results of operations.
 
     Change of Control Contingencies: In February 1998, the Company retained
investment bankers to assist the Company regarding the identification and
investigation of strategic alternatives that might be available to the Company,
including a possible sale of the Company. No such strategic transaction has been
negotiated to date, and there can be no assurance that any such strategic
transactions will be consummated. If a sale of the Company occurs, there can be
no assurance regarding the price per share to be received by the Company's
shareholders. Also, if a change of control of GTI occurs, the Company will owe
stay-on bonuses to certain employees aggregating approximately $1,200 and a
success fee to the investment bankers, depending on the price of the strategic
transaction, if any.

NOTE 10: STOCK-BASED COMPENSATION PLANS
 
     Stock Option Plans: The Company has five stock option plans that provide
for the granting of either incentive stock options or non-qualified stock
options to key employees and non-employee members of the Company's Board of
Directors. All current outstanding options are non-qualified stock options. The
options granted under these plans are to purchase common stock at not less than
fair-market value at the date of grant. Employee options are generally
exercisable one year from date of grant in cumulative annual installments of
25%, and they generally fully vest upon a change of control of GTI. Non-employee
director options are exercisable in full at the date of grant. The options have
terms of five to ten years.
 
     The following summarizes stock options activity for 1997:

     Additionally, as of December 31, 1997, a warrant was outstanding for
250,000 shares of common stock at an exercise price of $6 per share. This
warrant, issued to an affiliated party, expires 30 days after the note payable
to said affiliated party is paid in full. The anticipated retirement of said
note is February 1999.
 
     As permissible under Statement of Financial Accounting Standards No. 123,
the Company accounts for stock options granted as per the methodology prescribed
under Accounting Principles Board Opinion No. 25, which recognizes compensation
cost based upon the intrinsic value of the equity award. Accordingly, no
compensation expense was recognized in the consolidated statement of operations
for any equity awards granted during 1997, 1996 and 1995.
 
     The following table represents pro forma net income (loss) and pro forma
earnings (loss) per share had the Company elected to account for equity awards
using the fair-value-based method beginning with all equity award grants
commencing on January 1, 1995. In estimating the pro forma compensation expense
for each equity award granted during the years ended December 31, 1997, 1996 and
1995, the Company used the Black-Scholes option pricing model, a risk-free
interest rate of 6.5%, expected dividend yield of zero, expected option lives of
6.5 years, and expected volatility of 83.2%. The estimated pro forma
compensation cost resulting in the pro forma net income (loss) and earnings
(loss) per share may not be representative of actual results had the Company
accounted for equity awards using the fair-value-based method.

NOTE 11: EMPLOYEE BENEFIT PLANS
 
     The Company has a defined contribution plan that qualifies as a cash or
deferred profit sharing plan under Sections 401(a) and 401(k) of the Internal
Revenue Code. The plan is available to substantially all domestic employees.
Under the plan, participating employees may defer between 1% and 15% of their
pre-tax compensation. The Company contributes 50% for each dollar contributed
per employee up to a maximum of 3% of the employee's defined compensation. In
addition, the plan provides for an employer profit sharing contribution in such
amounts as the Board of Directors may annually determine. The Company also has
similar plans for foreign employees which are governed by the laws in the
country in which they are established. Company contributions under all plans
were $81, $120 and $145 in 1997, 1996 and 1995, respectively. There were no
amounts paid relating to the discretionary employer profit sharing contribution
in any of these years.
 
     The Company had no other programs that required payment of post-retirement
benefits to current or retired employees.

including a restructuring charge of about $1,500, subject to finalization, and
the cumulative effect of an accounting change of $899). In response to this
adverse trend and for other reasons, the Company has initiated ongoing revenue
enhancement and cost reduction programs. However, there can be no assurance that
revenues will increase, nor can there be any assurance that the Company will be
able to reduce costs in an amount sufficient to offset the negative effects of
the revenue decline. While management believes the Company has sufficient
financial resources, if revenue levels continue to decline, then the Company may
be forced to seek additional financing. There can be no assurance that
additional financing will be available in amounts or at terms acceptable to the
Company.
 
     In January 1998, the Company retained investment bankers to assist the
Company regarding the identification and investigation of strategic alternatives
that might be available to the Company, including a possible sale of the
Company. No such strategic transaction has been negotiated to date, and there
can be no assurance that any such strategic transaction will be consummated. If
a sale of the Company occurs in the short term, it is likely that the sales
price to be received by the Company's shareholders will be less than the
historical book value reflected in the accompanying December 31, 1997 balance
sheet.

             REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS ON SCHEDULES
 
To GTI Corporation:
 
     We have audited in accordance with generally accepted auditing standards
the consolidated financial statements included in this Form 10K, and have issued
our report thereon dated February 25, 1998. Our audits of the consolidated
financial statements were made for the purpose of forming an opinion on those
statements taken as a whole. The supplemental Schedule II is presented for
purposes of complying with the Securities and Exchange Commission's rules and is
not part of the basic financial statements. This supplemental schedule has been
subjected to the auditing procedures applied in the audits of the basic
financial statements and, in our opinion, fairly states in all material respects
the financial data required to be set forth therein in relation to the basic
financial statements taken as a whole.

                          AGREEMENT AND PLAN OF MERGER
 
     THIS AGREEMENT AND PLAN OF MERGER (this "Agreement") dated as of May 26,
1998 is by and among GTI CORPORATION, a Delaware corporation ("Company"),
TECHNITROL INTERNATIONAL, INC., a Delaware corporation ("Parent"), and

each (i) determined that the Merger (as defined in Section 1.1) is fair and in
the best interests of their respective stockholders and (ii) approved the Merger
in accordance with this Agreement.

and upon the terms and subject to the conditions of this Agreement and in

     SECTION 1.2. Effective Time. Subject to the terms and conditions set forth
in this Agreement, a Certificate of Merger (the "Merger Certificate") shall be
duly executed and acknowledged by Acquisition and the Company and thereafter
delivered to the Secretary of State of the State of Delaware for filing pursuant
to the DGCL on the Closing Date (as defined in Section 1.3). The Merger shall
become effective at such time as a properly executed and certified copy of the

in Section 5.1, 5.2 and 5.3 at the offices of Stradley, Ronon, Stevens & Young,
LLP, 2005 Market Street, Philadelphia, Pennsylvania 19103 unless another time,
date or place is agreed to in writing by the parties hereto.
 
     SECTION 1.4. Effects of the Merger. The Merger shall have the effects set
forth in this Agreement and in the applicable provisions of in the DGCL. Without

Incorporation of Acquisition in effect at the Effective Time shall be the
Certificate of Incorporation of the Surviving Corporation until amended in

Corporation until such director's successor is duly elected or appointed and
qualified.

<PAGE>   87
 
     SECTION 1.7. Officers. The officers of Acquisition at the Effective Time
shall be the initial officers of the Surviving Corporation, each to hold office
in accordance with the Certificate of Incorporation and Bylaws of the Surviving
Corporation until such officer's successor is duly elected or appointed and

     SECTION 1.8. Conversion of Shares.
 
     (a) At the Effective Time, each share of the Company's First Series
Cumulative Convertible Preferred Stock, par value $1.00 per share (individually
a "Preferred Share" and collectively the "Preferred Shares"), issued and
outstanding immediately prior to the Effective Time (other than (i) Preferred
Shares held in the Company's treasury or by any of the Company's subsidiaries
and (ii) Preferred Shares held by Parent, Acquisition or any other subsidiary of
Parent) shall, by virtue of the Merger and without any action on the part of
Parent, Acquisition, the Company, or the holder thereof, be converted into and
shall become the right to receive the product of (i) 234.314 multiplied by (ii)
$3.10 in cash, without interest (the "Preferred Merger Consideration").
Notwithstanding the foregoing, if between the date of this Agreement and the
Effective Time, the Preferred Shares shall have been changed into a different
number of shares or a different class by reason of any stock dividend,
subdivision, reclassification, recapitalization, split, combination or exchange
of shares then the Merger Consideration contemplated by the Merger shall be
correspondingly adjusted to reflect such stock dividend, subdivision,
reclassification, recapitalization, split, combination or exchange of shares.
 
     (b) At the Effective Time, each share of the Company's common stock, par
value $0.04 per share (individually a "Common Share" and collectively the
"Common Shares"; together with the Preferred Shares, the "Shares"), issued and
outstanding at the Effective Time, (other than (i) Common Shares held in the
Company's treasury or by any of the Company's subsidiaries and (ii) Common
Shares held by Parent, Acquisition or any other subsidiary of Parent) shall, by
virtue of the Merger and without any action on the part of Parent, Acquisition,
the Company or the holder thereof, be converted into and shall become the right
to receive $3.10 in cash, without interest (the "Common Merger Consideration,"
which together with the Preferred Merger Consideration, the "Merger
Consideration"). Notwithstanding the foregoing, if between the date of this
Agreement and the Effective Time, the Common Shares shall have been changed into
a different number of shares or a different class by reason of any stock
dividend, subdivision, reclassification, recapitalization, split, combination or
exchange of shares then the Merger Consideration contemplated by the Merger
shall be correspondingly adjusted to reflect such stock dividend, subdivision,
reclassification, recapitalization, split, combination or exchange of shares.
 
     (c) At the Effective Time, each outstanding share of the common stock, par
value $0.01 per share, of Acquisition shall be converted into one share of
common stock, par value $0.04 per share, of the Surviving Corporation.
 
     (d) At the Effective Time, each Common Share held in the treasury of the
Company and each Common Share held by Parent, Acquisition or any subsidiary of
Parent, Acquisition or the Company immediately prior to the Effective Time
shall, by virtue of the Merger and without any action on the part of
Acquisition, the Company or the holder thereof, be canceled, retired and cease
to exist and no payment shall be made with respect thereto.
 
     SECTION 1.9. Shares of Dissenting Holders.
 
     (a) Notwithstanding anything to the contrary contained in this Agreement,
any holder of Shares with respect to which dissenters' rights, if any, are
granted by reason of the Merger under the DGCL and who does not vote in favor of
or consent in writing to the Merger and who otherwise complies with the DGCL
("Company Dissenting Shares") shall not be entitled to receive any Merger
Consideration pursuant to Section 1.8 (a) or (b), but shall be entitled to
receive payment of the appraised value of such shares held by such holder in
accordance with the provisions of Section 262 of the DGCL, unless such holder
fails to perfect, effectively withdraws or loses his or her right to dissent
from the Merger under the DGCL. If any such holder so fails to perfect,
effectively withdraws or loses his or her dissenters' rights under the DGCL,
each Company Dissenting Share of such holder shall thereupon be deemed to have
been converted, as of the Effective Time, into the right to receive the Merger
Consideration pursuant to Section 1.8(a) and/or (b).
 
                                       A-2
<PAGE>   88
 
     (b) Any payments relating to Company Dissenting Shares shall be made solely
by the Surviving Corporation and no funds or other property have been or will be
provided by Acquisition, Parent or any of Parent's other direct or indirect
subsidiaries for such payment, nor shall the Company make any payment with
respect to, or settle or offer to settle, any such demands.
 
     (c) The Company shall give Acquisition (i) prompt notice of any demands
received by the Company for the payment of fair value for shares, withdrawals of
such demands and any other instruments served pursuant to the DGCL and received
by the Company which relate to such demand for appraisal, and (ii) 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 the Acquisition,
voluntarily make any payment with respect to any demands for appraisal of the
Shares or offer to settle or settle any such demands.
 
     SECTION 1.10. Payment of Merger Consideration.
 
     (a) No later than the Effective Time, as required by subsection (b) below,
Parent shall deposit with Registrar and Transfer Company or such other agent or
agents as may be appointed by Parent and Acquisition (the "Payment Agent") for
the benefit of the holders of Shares in cash the aggregate amount necessary to
pay the Merger Consideration (such cash is hereinafter referred to as the
"Merger Fund") payable pursuant to Section 1.8 in exchange for outstanding
Shares.
 
     (b) As soon as reasonably practicable after the Effective Time, the Payment
Agent shall mail to each holder of record of a certificate or certificates which
immediately prior to the Effective Time represented outstanding Shares (the
"Certificates") whose shares were converted into the right to receive the Merger
Consideration pursuant to Section 1.8: (i) a letter of transmittal (which shall
specify that delivery shall be effected and risk of loss and title to the
Certificates shall pass only upon delivery of the Certificates to the Payment
Agent and shall be in such form and have such other provisions as Parent and the
Company may reasonably specify) and (ii) instructions for use in effecting the
surrender of the Certificates in exchange for the Merger Consideration. Upon
surrender of a Certificate for cancellation to the Payment Agent, together with
such letter of transmittal duly executed, the holder of such Certificate shall
be entitled to receive in exchange therefor a check representing the Merger
Consideration which such holder has the right to receive pursuant to the
provisions of this Article 1 and the Certificate so surrendered shall forthwith
be canceled. In the event of a transfer of ownership of Shares which is not
registered in the transfer records of the Company, payment of the Merger
Consideration may be made to a transferee if the Certificate representing such
Shares is presented to the Payment Agent accompanied by all documents required
to evidence and effect such transfer and by evidence that any applicable stock
transfer taxes have been paid. Until surrendered as contemplated by this Section
1.10, each Certificate shall be deemed at any time after the Effective Time to
represent only the right to receive upon such surrender the Merger Consideration
as contemplated by this Section 1.10. No interest shall be paid on the Merger
Consideration.
 
     (c) In the event that any Certificate for Shares shall have been lost,
stolen or destroyed, the Payment Agent shall issue in exchange therefor, upon
the making of an affidavit of that fact by the holder thereof, such Merger
Consideration as may be required pursuant to this Agreement; provided, however,
that Parent or its Payment Agent may, in its discretion, require as a condition
precedent thereto the delivery of a suitable bond or indemnity.
 
     (d) All Merger Consideration paid upon the surrender for exchange of Shares
in accordance with the terms hereof shall be deemed to have been paid in full
satisfaction of all rights pertaining to such Shares; subject, however, to the
Surviving Corporation's obligation to pay any dividends or make any other
distributions with a record date prior to the Effective Time which may have been
declared or made by the Company on such Shares in accordance with the terms of
this Agreement, or prior to the date hereof and which remain unpaid at the
Effective Time, and at the Effective Time there shall be no further registration
of transfers on the stock transfer books of the Surviving Corporation of the
Shares which were outstanding immediately prior to the Effective Time. If after
the Effective Time, Certificates are presented to the Surviving Corporation for
any reason they shall be canceled and exchanged as provided in this Article 1.

<PAGE>   89
 
     (e) Neither Parent nor the Company shall be liable to any holder of Shares
for cash delivered to a public official pursuant to any applicable abandoned
property, escheat or similar law.
 
     (f) Any portion of the Merger Fund which remains undistributed to the
holders of Shares for one (1) year after the Effective Time shall be delivered
to Parent, upon demand, and any holders of Shares who have not theretofore
complied with this Article 1 shall thereafter look only to Parent for the Merger
Consideration to which they are entitled.
 
     (g) Parent shall be entitled to deduct and withhold from the consideration
otherwise payable pursuant to this Agreement to any holder of Shares such
amounts as Parent is required to deduct and withhold with respect to the making
of such payment under the Internal Revenue Code of 1986, as amended (the
"Code"), or any provision of state, local or foreign tax law. To the extent that
amounts are so withheld by Parent and paid by Parent to the appropriate
Governmental Entity (as described below), such withheld amounts shall be treated
for all purposes of this Agreement as having been paid to the holder of the
Shares in respect of which such deduction and withholding was made by Parent.
 
     (h) If, at any time after the Effective Time, any further action is
necessary or desirable to carry out the purposes of this Agreement and to vest
the Surviving Corporation with full right, title and possession to all assets,
property, rights, privileges, powers and franchises of the Company and
Acquisition, the officers and directors of the Company and Acquisition are fully
authorized in the name of their respective corporations or otherwise to take,
and will take, all such lawful and necessary action, so long as such action is
consistent with this Agreement.
 
     SECTION 1.11. Stock Options. At the Effective Time, each outstanding option
to purchase Shares (a "Company Stock Option" or collectively "Company Stock
Options"), whether vested or unvested, issued pursuant to any of the Company's
stock option plans (the "Company Plans") (including by reason of the
transactions contemplated by this Agreement), and each outstanding Warrant to
purchase shares of the Company's capital stock, shall be canceled, and each
holder of a Company Stock Option shall be entitled to receive in exchange
therefor cash in an amount equal to the product of (x) the amount, if any, by
which $3.10 exceeds the exercise price of such Company Stock Option, multiplied
by (y) the number of Shares subject to such Company Stock Option, less
applicable tax withholding. At or before the Effective Time, the Company shall
cause to be effected any necessary amendments to the Company Plans to give
effect to the provisions of this Section 1.11.
 
     SECTION 1.12. Payment of Note. Immediately prior to the Effective Time, the
Company shall repay in full to Telemetrix PLC, a corporation organized under the
laws of England and Wales ("Telemetrix") or its designee, that certain Note,
made by Valor Electronics, Inc. to Telemetrix in the original principal amount
of $2.5 million, dated February 10, 1997, together with all accrued but unpaid
interest through the date of payment.
 
                                   ARTICLE 2
 
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
     Except as set forth on the Disclosure Schedule attached hereto (the
"Company Disclosure Schedule") or in the Company SEC Reports (as defined in
Section 2.4(a)), the Company hereby represents and warrants to each of Parent
and Acquisition as follows:
 
     SECTION 2.1. Organization and Qualification; Subsidiaries.
 
     (a) Schedule 2.1 identifies each subsidiary of the Company as of the date
hereof and its respective jurisdiction of incorporation or organization, as the
case may be. Except as set forth in Schedule 2.1, the Company does not directly
or indirectly own any equity or similar interest in, or any interest convertible
into or exchangeable or exercisable for any interest in, any corporation,
partnership, joint venture or other business association or entity other than
the securities of any publicly-traded entity held for investment only and
constituting less than 5% of the outstanding capital stock of any such entity.
Each of the Company and its subsidiaries is duly organized, validly existing and
in good standing under the laws of the jurisdiction of its
 
                                       A-4
<PAGE>   90
 
incorporation or organization and has all requisite power and authority to own,
lease and operate its properties and to carry on its businesses as now being
conducted. The Company has heretofore delivered to Acquisition or Parent
accurate and complete copies of the Certificate of Incorporation and Bylaws (or
similar governing documents), as currently in effect, of the Company and its
subsidiaries.
 
     (b) Each of the Company and its subsidiaries is duly qualified or licensed
and in good standing to do business in each jurisdiction in which the property
owned, leased or operated by it or the nature of the business conducted by it
makes such qualification or licensing necessary, except in jurisdictions where
the failure to be so duly qualified or licensed and in good standing would not
have a Material Adverse Effect (as defined below) on the Company. When used in
connection with the Company or its subsidiaries, the term "Material Adverse
Effect" means any material adverse change or effect (i) on the business, results
of operations or condition (financial or otherwise) of the Company and its
subsidiaries, taken as whole, other than any change or effect arising out of
general economic conditions (including, without limitation, levels of aggregate
demand, interest rates, currency exchange rates and applicable tax laws), or
(ii) that would impair the ability of the Company to consummate the transactions
contemplated hereby.
 
     SECTION 2.2. Capitalization of the Company and its Subsidiaries.
 
     (a) The authorized capital stock of the Company consists of 12,000,000
Common Shares, of which, as of May 25, 1998, 8,973,475 Shares were issued and
outstanding and 1,000,000 Preferred Shares of which, as of May 25, 1998, 8,110
Preferred Shares were issued and outstanding. All of the outstanding Common
Shares and Preferred Shares have been duly authorized, validly issued and are
fully paid, nonassessable and free of preemptive rights. As of May 25, 1998,
approximately 984,250 Common Shares were reserved for issuance and issuable upon
or otherwise deliverable in connection with the exercise of outstanding Company
Stock Options issued pursuant to the Company Plans. Schedule 2.2(a) sets forth a
list of each outstanding option as of May 25, 1998, the name of the holder, the
vesting date, and if exercisability or vesting will be accelerated in any way in
connection with the consummation of the transactions contemplated in this
Agreement. Between January 1, 1998 and the date hereof, no shares of the
Company's capital stock have been issued other than pursuant to Company Stock
Options already in existence on such date, and between January 1, 1998 and the
date hereof no stock options have been granted. Except as set forth above, as of
the date hereof, there are outstanding (i) no shares of capital stock or other
voting securities of the Company, (ii) no securities of the Company or its
subsidiaries convertible into or exchangeable for shares of capital stock or
voting securities of the Company except for the Preferred Shares, (iii) no
options, warrants (other than warrants issued to Telemetrix and described in the
Company's annual report on Form 10-K/A for the fiscal year ended December 31,
1997) or other rights to acquire from the Company or its subsidiaries and,
except as described in Schedule 2.2(a), no obligations of the Company or its
subsidiaries to issue any capital stock, voting securities or securities
convertible into or exchangeable for capital stock or voting securities of the
Company or to grant, extend, accelerate the vesting of, change the price of, or
otherwise amend any such options, warrants (other than warrants issued to
Telemetrix and described in the Company's annual report on Form 10-K/A for the
fiscal year ended December 31, 1997), calls, rights, commitments or agreements
and (iv) no equity equivalent interests in the ownership or earnings of the
Company or its subsidiaries or other similar rights (collectively "Company
Securities"). As of the date hereof, there are no outstanding obligations of the
Company or its subsidiaries to repurchase, redeem or otherwise acquire any
Company Securities. Except as set forth on Schedule 2.2(a), there are no
stockholder agreements, voting trusts or other agreements or understandings to
which the Company is a party or by which it is bound relating to the voting or
registration of any shares of capital stock of the Company. Since March 31, 1998
there have been no changes in the capital structure of the Company other than
issuances of Common Shares upon exercise of outstanding options granted under
the Company Plans.
 
     (b) Except as set forth on Schedule 2.2(b), all of the outstanding capital
stock of the Company's subsidiaries (other than director's qualifying shares in
the case of foreign subsidiaries) is owned by the Company, directly or
indirectly, free and clear of any Lien (as defined below) or any other
limitation or restriction (including any restriction on the right to vote or
sell the same except as may be provided as a matter of law). Except as set forth
on Schedule 2.2(b), there are no securities of the Company or its subsidiaries
convertible into or exchangeable for, no options, warrants or other rights to
acquire from the
 
                                       A-5
<PAGE>   91
 
Company or its subsidiaries and no other contract, understanding, arrangement or
obligation (whether or not contingent) providing for, the issuance or sale,
directly or indirectly, of any capital stock or other ownership interests in or
any other securities of any subsidiary of the Company. Except as set forth on
Schedule 2.2(b), there are no outstanding contractual obligations of the Company
or its subsidiaries to repurchase, redeem or otherwise acquire any outstanding
shares of capital stock or other ownership interests in any subsidiary of the
Company. For purposes of this Agreement, "Lien" means, with respect to any asset
(including without limitation any security), any mortgage, lien, pledge, charge,
security interest or encumbrance of any kind in respect of such asset.
 
     (c) The Common Shares constitute the only class of equity securities of the
Company or its subsidiaries registered or required to be registered under the
Securities Exchange Act of 1934, as amended (the "Exchange Act").
 
     SECTION 2.3. Authority Relative to this Agreement, Recommendation.
 
     (a) The Company has all necessary 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 the Company (the "Company Board") and no other corporate
proceedings on the part of the Company are necessary to authorize this Agreement
or to consummate the transactions contemplated hereby except the approval and
adoption of this Agreement by the holders of a majority of the outstanding
Common Shares and two-thirds of the outstanding Preferred Shares, voting as a
separate class. This Agreement has been duly and validly executed and delivered
by the Company and constitutes a valid, legal and binding agreement of the
Company enforceable against the Company in accordance with its terms.
 
     (b) The Company Board has voted to recommend that the stockholders of the
Company approve and adopt this Agreement.
 
     SECTION 2.4. SEC Reports, Financial Statements.
 
     (a) The Company has filed all required forms, reports and documents and all
amendments and supplements thereto with the Securities and Exchange Commission
(the "SEC") since December 31, 1995 and will file with the SEC after the date of
this Agreement through the Effective Time all required forms, reports and
documents and amendments and supplements thereto, (collectively, "Company SEC
Reports"), each of which has complied or when filed, will comply, in all
material respects with all applicable requirements of the Securities Act of
1933, as amended (the "Securities Act") and the Exchange Act and the rules and
regulations promulgated thereunder, each as in effect on the dates such forms,
reports and documents were filed. None of such Company SEC Reports, including,
without limitation, any financial statements (and the related notes thereto) or
schedules included or incorporated by reference therein, contained or will
contain when filed any untrue statement of a material fact or omitted to state a
material fact required to be stated or incorporated by reference therein or
necessary in order to make the statements therein in light of the circumstances
under which they were made not misleading. The audited consolidated financial
statements of the Company included in the Company SEC Reports fairly present in
conformity with generally accepted accounting principles applied on a consistent
basis (except as may be indicated in the notes thereto), the consolidated
financial position of the Company and its consolidated subsidiaries as of the
dates thereof and their consolidated results of operations and cash flows for
the periods then ended. None of the Company's subsidiaries is required to file
any reports or other documents with the SEC.
 
     (b) The Company has heretofore furnished to Acquisition or Parent a
complete and correct copy of any amendments or modifications which are required
to be filed with the SEC but have not yet been filed with the SEC to agreements,
documents or other instruments which previously had been filed by the Company
with the SEC pursuant to the Securities Act or Exchange Act.
 
     SECTION 2.5. Information Supplied. None of the information supplied or to
be supplied by the Company for inclusion or incorporation by reference in the
proxy statement relating to the meeting of the Company's stockholders to be held
in connection with the Merger (the "Proxy Statement") will, at the date mailed
to stockholders of the Company and at the time of the meeting of stockholders of
the Company to be
 
                                       A-6
<PAGE>   92
 
held in connection with the Merger, 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 therein in light of the circumstances
under which they are made not misleading.
 
     SECTION 2.6. Consents and Approvals, No Violations. Except for filings,
permits, authorizations, consents and approvals as may be required under and
other applicable requirements of the Exchange Act, state securities or blue sky
laws, the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the
"HSR Act") and the filing and recordation of the Merger Certificate as required
by the DGCL, no filing with or notice to and no permit, authorization, consent
or approval of any court or tribunal, or administrative governmental or
regulatory body, agency or authority, domestic or, to the Company's knowledge,
foreign, (a "Governmental Entity") is necessary for the execution and delivery
by the Company of this Agreement or the consummation by the Company of the
transactions contemplated hereby, except where the failure to obtain such
permits, authorizations, consents or approvals or to make such filings or give
such notice would not have a Material Adverse Effect on the Company. Neither the
execution, delivery and performance of this Agreement by the Company nor the
consummation by the Company of the transactions contemplated hereby will (i)
conflict with or result in any breach of any provision of the respective
Certificate of Incorporation or Bylaws (or similar governing documents) of the
Company or any of its subsidiaries, (ii) except as set forth in Schedule 2.6,
result in a violation or breach of or constitute (with or without due notice or
lapse of time or both) a default (or give rise to any right of termination,
amendment, cancellation or acceleration of any obligation or loss of any
benefits or creation of any Lien) under any of the terms, conditions or
provisions of any note, bond, mortgage, indenture, lease, license, contract,
agreement or other instrument or obligation to which the Company or any of its
subsidiaries is a party or by which any of them or any of their respective
properties or assets may be bound or (iii) violate any order, writ, injunction,
decree, law, statute, rule or regulation applicable to the Company or any of its
subsidiaries or any of their respective properties or assets except, in the case
of (ii) or (iii), for violations, breaches or defaults which would not have a
Material Adverse Effect on the Company.
 
     SECTION 2.7. No Default. Except as set forth in Schedule 2.7, none of the
Company or its subsidiaries is in breach, default or violation (and no event has
occurred which with notice or the lapse of time or both would constitute a
breach, default or violation) of any term, condition or provision of (i) its
Certificate of Incorporation or Bylaws (or similar governing documents), (ii)
any note, bond, mortgage, indenture, lease, license, contract, agreement or
other instrument or obligation to which the Company or any of its subsidiaries
is now a party or by which any of them or any of their respective properties or
assets may be bound or (iii) any order, writ, injunction, decree, law, statute,
rule or regulation applicable to the Company or any of its subsidiaries or any
of their respective properties or assets except, in the case of (ii) or (iii),
for violations, breaches or defaults that would not have a Material Adverse
Effect on the Company.
 
     SECTION 2.8. No Undisclosed Liabilities, Absence of Changes. Except as and
to the extent publicly disclosed by the Company in the Company SEC Reports, as
of December 31, 1997, none of the Company or its subsidiaries had any
liabilities or obligations of any nature, whether or not accrued, contingent or
otherwise, that would be required by generally accepted accounting principles to
be reflected on a consolidated balance sheet of the Company (including the notes
thereto) or that would have a Material Adverse Effect on the Company. Except as
publicly disclosed by the Company in the Company SEC Reports or in the
disclosure schedules hereto, since March 28, 1998, the Company and its
subsidiaries have conducted their business only in the ordinary course and in a
manner consistent with past practices and none of the Company or its
subsidiaries has incurred any liabilities of any nature, whether or not accrued,
contingent or otherwise, and there have been no events, changes or effects with
respect to the Company or its subsidiaries, having a Material Adverse Effect on
the Company.
 
     SECTION 2.9. Litigation. Except as publicly disclosed by the Company in the
Company SEC Reports, there is no suit, claim, action, proceeding, arbitration or
investigation pending or, to the knowledge of the Company, threatened against
the Company or any of its subsidiaries or any of their respective properties or
assets before any Governmental Entity or arbitrator which individually or in the
aggregate would have a Material Adverse Effect on the Company or seeks to
prevent or delay the consummation of the transactions contemplated by this
Agreement. Except as publicly disclosed by the Company in the Company SEC
Reports,
 
                                       A-7
<PAGE>   93
 
none of the Company or its subsidiaries is subject to any outstanding order,
writ, injunction or decree which has a Material Adverse Effect on the Company or
would prevent or delay the consummation of the transactions contemplated hereby.
 
     SECTION 2.10. Compliance with Applicable Law. Except as set forth in
Schedule 2.10, the Company and its subsidiaries hold all permits, licenses,
variances, exemptions, orders and approvals of all Governmental Entities
necessary for the lawful conduct of their respective businesses (the "Company
Permits") except for failures to hold such permits, licenses, variances,
exemptions, orders and approvals which would not have a Material Adverse Effect
on the Company. The Company and its subsidiaries are in compliance with the
terms of the Company Permits except where the failure so to comply would not
have a Material Adverse Effect on the Company. The businesses of the Company and
its subsidiaries are not being conducted in violation of any law, ordinance or
regulation of any Governmental Entity, except that no representation or warranty
is made in this Section 2.10 with respect to Environmental Laws (as defined in
Section 2.12 below) and except for violations or possible violations which do
not and, insofar as reasonably can be foreseen will not, have a Material Adverse
Effect on the Company. There are no products now being manufactured, assembled
or sold by the Company or any of its subsidiaries which at the date hereof would
require any approval of any governmental body, whether federal, state, local or
foreign for the purpose for which they are being manufactured, assembled or sold
by the Company or any of its subsidiaries, for which such approval has not been
obtained, except where the failure to obtain such approval does not,
collectively, have a Material Adverse Effect on the Company. All products now
being commercially distributed by the Company or any of its subsidiaries in any
jurisdiction meet the applicable legal requirements of such jurisdiction and all
requisite governmental approvals have been duly obtained and are in full force
and effect, and there is no basis known to the Company or any of its
subsidiaries for any governmental body to deny or rescind any approval for any
of their commercially distributed products for the purpose for which they are
being manufactured, assembled or sold or for any products that the Company or
any of its subsidiaries proposes to commercially distribute in the future,
except where the failure to meet such requirements, the failure to obtain such
approvals or the failure of such approvals to be in full force and effect, does
not, collectively, have, and such denial or rescission, insofar as reasonably
can be foreseen would not, collectively, have a Material Adverse Effect on the
Company.
 
     No investigation or review by any Governmental Entity with respect to the
Company or its subsidiaries is pending or, to the knowledge of the Company,
threatened nor, to the knowledge of the Company, has any Governmental Entity
indicated an intention to conduct the same, other than such investigations or
reviews as would not, individually or in the aggregate, have a Material Adverse
Effect on the Company.
 
     SECTION 2.11. Employee Benefit Plans, Labor Matters.
 
     (a) Schedule 2.11(a) lists all employee benefit plans (as defined in
Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA")) and all bonus, stock option, stock purchase, incentive, deferred
compensation, supplemental retirement, severance and other similar fringe or
employee benefit plans, programs or arrangements and any current or former
employment, executive compensation or severance agreements, written or
otherwise, maintained or contributed to, for the benefit of or relating to any
employee of the Company, any trade or business (whether or not incorporated)
which is a member of a controlled group including the Company or which is under
common control with the Company within the meaning of Section 414 of the Code
(an "ERISA Affiliate") as well as each plan with respect to which the Company or
an ERISA Affiliate could incur liability under Section 4069 (if such plan has
been or were terminated) or Section 4212(c) of ERISA (together the "Employee
Plans"), excluding former agreements under which the Company has no remaining
material obligations and any of the foregoing that are required to be maintained
by the Company under the laws of any foreign jurisdiction. The Company has made
available to Parent a copy of (i) the most recent annual report on Form 5500
filed with the Internal Revenue Service (the "IRS") for each disclosed Employee
Plan where such report is required, (ii) the documents and instruments governing
each such Employee Plan (other than those referred to in Section 4(b)(4) of
ERISA) and (iii) the summary plan description for each Employee Plan which is
subject to ERISA. Except as set forth in Schedule 2.11(a), no event has occurred
and, to the knowledge of the Company, there currently exists no condition or set
of circumstances in connection with which the Company or any of its subsidiaries
could be subject to any liability under the terms of any Employee Plans, ERISA,
the Code or any other applicable law,
 
                                       A-8
<PAGE>   94
 
including, without limitation, any liability under Title IV of ERISA, which
would have a Material Adverse Effect on the Company.
 
     (b) Schedule 2.11(b) sets forth a list of (i) all employment agreements
with officers of the Company and its subsidiaries; (ii) all agreements with
consultants who are individuals obligating the Company or any of its
subsidiaries to make annual cash payments in an amount exceeding $50,000; (iii)
all severance agreements, programs and policies of the Company and its
subsidiaries with or relating to its employees except programs and policies
required to be maintained by law; and (vi) plans, programs agreements and other
arrangements of the Company and its subsidiaries with or relating to its
employees which contain change in control provisions. The Company has made
available to Parent copies (or descriptions in detail reasonably satisfactory to
Parent) of all such agreements, plans, programs and other arrangements.
 
     (c) Except as disclosed in Schedule 2.11(c) of the Company Disclosure
Schedule, there will be no payment, accrual of additional benefits, acceleration
of payments or vesting in any benefit under any Employee Plan or any agreement
or arrangement disclosed under this Section 2.11 solely by reason of entering
into or in connection with the transactions contemplated by this Agreement. No
such payment will constitute an "excess parachute payment" within the meaning of
Section 280G of the Code.
 
     (d) No Employee Plan provides post-retirement medical or welfare benefits
to former employees of the Company or its ERISA Affiliates other than pursuant
to Section 4980B of the Code.
 
     (e) There are no controversies pending or, to the knowledge of the Company,
threatened between the Company or any of its subsidiaries and any of their
respective employees, or involving any Employee Plan, which controversies have a
Material Adverse Effect on the Company. Neither the Company nor any of its
subsidiaries is a party to any collective bargaining agreement or other labor
union contract applicable to persons employed by the Company or its subsidiaries
except as disclosed in Schedule 2.11(e) nor does the Company know of any
activities or proceedings of any labor union to organize any such employees. The
Company has no knowledge of any strikes, slowdowns, work stoppages, lockouts or
threats thereof by or with respect to any employees of the Company or any of its
subsidiaries.
 
     (f) Each Employee Plan has been maintained in material compliance with all
applicable laws, including, without limitation, ERISA and the Code. Each
Employee Plan has been maintained in material conformance with the terms and
provisions of such Plan.
 
     (g) Each Employee Plan which is intended to be qualified under Section
401(a) of the Code, and exempt from tax under Section 501(a) of the ode, is the
subject of an unrevoked favorable determination letter from the Internal Revenue
Service. To the best knowledge of Company, nothing has occurred since the date
of any such letter which may adversely affect such qualification or exemption
(other than changes in applicable law that have occurred since the date of such
letter and for which the remedial amendment period of Section 401(b) of the Code
has not expired as of the date hereof).
 
     (h) The Company and its ERISA Affiliates have made all payments and
contributions to the Employee Plans on a timely basis as required by the terms
of each such Employee Plan and any applicable law.
 
     (i) The Company and its ERISA Affiliates have filed or caused to be filed
with the Internal Revenue Service annual reports on the applicable Form 5500
series for each Employee Plan for all years and periods for which such reports
were required and within the time period required by ERISA and the Code.
 
     (j) No "prohibited transaction", as defined in Section 406 of ERISA and
Section 4975 of the Code, has occurred with respect to any Employee Plan, and,
to the best knowledge of the Company, no civil or criminal action brought
pursuant to Part V, Title I of ERISA is pending or threatened in writing or
orally against any fiduciary of any such Employee Plan.
 
     (k) Neither the Company nor any ERISA Affiliate currently maintains any
Employee Plan that is subject to Title IV of ERISA (other than a multi-employer
plan, within the meaning of Section 3(37) or 4001(a)3 of ERISA) nor has
previously maintained any such Plan that has resulted in any liability or
potential liability for the Company or its ERISA Affiliates under said Title IV.
 
                                       A-9
<PAGE>   95
 
     (l) Neither the Company nor any ERISA Affiliate maintains, or has
contributed to within the past five years, any multi-employer plan, within the
meaning of Section 3(37) or 4001(a)3 of ERISA. Neither the Company nor any ERISA
Affiliate has any liability to make withdrawal liability payments to any multi-
employer plan.
 
     (m) Each Employee Plan that is a group health plan sponsored or maintained
by the Company or any ERISA Affiliate has been operated in material compliance
with the applicable requirements of Parts 6 and 7 of Subtitle B of Title I of
ERISA and Sections 4980(B)(f), 9801 and 9802 of the Code. The Company has not
contributed to a non-conforming group health plan, as that term is defined in
Section 5000(c) of the Code or incurred any tax liability under Section 5000(a)
of the Code that would have a Material Adverse Affect.
 
     (n) Neither the Company nor any ERISA Affiliate has incurred any excise tax
liability with respect to any Employee Plan which has not been satisfied.
 
     SECTION 2.12. Environmental Laws and Regulations.
 
     (a)(i) Except as publicly disclosed by the Company in the Company SEC
Reports or in Schedule 2.12 to this Agreement, (i) each of the Company and its
subsidiaries is in material compliance with all U.S. Environmental Laws (as
defined below) and, to the actual knowledge of the Company, all Foreign
Environmental Laws (as defined below), except for non-compliance that would not
have a Material Adverse Effect on the Company, which compliance includes but is
not limited to, the possession by the Company and its subsidiaries of all
material permits and other governmental authorizations required under applicable
U.S. Environmental Laws and, to the actual knowledge of the Company, Foreign
Environmental Laws and compliance with the terms and conditions thereof, (ii)
none of the Company or its subsidiaries have knowledge of an existing or
potential Environmental Claim (as defined below) against the Company or its
subsidiaries or, to the knowledge of the Company, against any person or entity
whose liability for any Environmental Claim the Company or any of its
subsidiaries has or may have retained or assumed either contractually or by
operation of law, that have or would reasonably be expected to have a Material
Adverse Effect on the Company; and (iii) to the best knowledge of the Company,
there are no circumstances that are reasonably likely to prevent or interfere
with such material compliance in the future.
 
     (b) Except as disclosed in the Company SEC Reports, or except as would not
have a Material Adverse Effect on the Company, (i) there have been no releases
(i.e., any past or present releasing, spilling, leaking, pumping, pouring,
emitting, emptying, discharging, injecting, escaping, leaching, disposing or
dumping) of Hazardous Substances (as defined below) by the Company or its
current or former subsidiaries on, under, upon or into any real properties owned
or leased currently or in the past by the Company or its current or former
subsidiaries, (ii) no underground tank for Hazardous Substances or relating

its subsidiaries to be in violation or default under any such license,
sublicense or agreement, nor entitle any other party to any such license,

     SECTION 2.21. Non-Public Information Provided to Parent. The non-public

contain any material misstatement of a material fact. The written projections of
the Company's future financial performance provided by the Company to Parent
were prepared in good faith based on assumptions believed by the Company to be
reasonable as of the date such projections were provided to Parent and as of the
date of this Agreement; however no other representation is made or to be implied
concerning such projections, and Parent and Acquisition acknowledge the
inherently uncertain, risky and speculative nature of such projections.

            REPRESENTATIONS AND WARRANTIES OF PARENT AND ACQUISITION
 
     Parent and Acquisition hereby represent and warrant to the Company as
follows:
 
     SECTION 3.1. Organization.
 
     (a) Each of Parent and Acquisition is duly organized, validly existing and
in good standing under the laws of the Commonwealth of Pennsylvania and the
State of [Delaware], respectively, and has all requisite power and authority to
own, lease and operate its properties and to carry on its businesses as now
being conducted. Parent has heretofore delivered to the Company accurate and
complete copies of the Certificate of Incorporation and Bylaws as currently in
effect of Parent and Acquisition.
 
     (b) Each of Parent and Acquisition is duly qualified or licensed and in
good standing to do business in each jurisdiction in which the property owned,
leased or operated by it or the nature of the business conducted by it makes
such qualification or licensing necessary, except in such jurisdictions where
the failure to be so duly qualified or licensed and in good standing would not
have a Material Adverse Effect on Parent. When used in connection with Parent or
Acquisition the term "Material Adverse Effect" means any material adverse change
or effect (i) on the business, results of operations or condition (financial or
otherwise) of Parent and its subsidiaries, taken as a whole, other than any
change or effect arising out of general economic conditions (including, without

Acquisition to consummate the transactions contemplated hereby.
 
     SECTION 3.2. Authority Relative to this Agreement. Each of Parent and
Acquisition has all necessary corporate power and authority to execute and

The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly and validly authorized by the
boards of directors of Parent and Acquisition and by Parent as the sole
stockholder of Acquisition and no other corporate proceedings on the part of
Parent or Acquisition are necessary to authorize this Agreement or to consummate
the transactions contemplated hereby. This Agreement has been duly and validly
executed and delivered by each of Parent and Acquisition and constitutes a

default or violation (and no event has occurred which with notice or the lapse
of time or both would constitute a breach, default or violation) of any term,
condition or provision of (i) its Certificate of Incorporation or Bylaws (or
similar governing documents), (ii) any note, bond, mortgage, indenture, lease,
license, contract, agreement or other instrument or obligation to which Parent
or any of its subsidiaries is now a party or by which any of injunction, decree,
law, statute, rule or regulation applicable to Parent or any of its subsidiaries

<PAGE>   102
 
authorizations, consents or approvals or to make such filings or give such
notice would not materially impair the likelihood of the consummation of the
transactions contemplated hereby and the likelihood that such transactions would
not be rescinded or undone. Neither the execution, delivery and performance of
this Agreement by Parent or Acquisition nor the consummation by Parent or
Acquisition of the transactions contemplated hereby will (i) conflict with or
result in any breach of any provision of the respective Certificate of
Incorporation or Bylaws (or similar governing documents) of Parent or
Acquisition or any of Parent's other subsidiaries, (ii) result in a violation or
breach of or constitute (with or without due notice or lapse of time or both) a
default (or give rise to any right of termination, amendment, cancellation or
acceleration or Lien) under any of the terms conditions or provisions of any
note, bond, mortgage, indenture, lease, license, contract, agreement or other
instrument or obligation to which Parent or Acquisition or any of Parent's other

properties or assets may be bound or (iii) violate any order, writ, injunction,
decree, law, statute, rule or regulation applicable to Parent or Acquisition or
any of Parent's other subsidiaries or any of their respective properties or
assets except, in the case of (ii) or (iii), for violations breaches or defaults
which would not materially impair the likelihood of the consummation of the
transactions contemplated hereby and the likelihood that such transactions would
not be rescinded or undone.

     SECTION 4.2. Preparation of the Proxy Statement. The Company shall, as
promptly as practicable prepare and file with the SEC the Proxy Statement. The
Proxy Statement shall also include the recommendation of the Board of Directors
of the Company in favor of the Merger, which shall not be withdrawn, modified or
withheld except in compliance with the fiduciary duties of the Company's Board
under applicable law or in compliance with Section 4.4 hereof. To Company's best
knowledge, at the time the Proxy Statement is mailed to the stockholders of the
Company, the Proxy Statement will comply as to form in all material respects
with the provisions of the Exchange Act and the rules and regulations
thereunder. If at any time prior to the Effective Time any information relating
to the Company or any of its affiliates, officers or directors should be
disclosed by the Company in an amendment or a supplement to the Proxy Statement,

          (c) Promptly provide to Parent copies of all such SEC filings, and SEC
     written communications, as well as copies of all written communications
     with stockholders generally.
 
     SECTION 4.4. Other Potential Acquirers.
 
     (a) Neither the Company nor any of its subsidiaries shall, nor shall the
Company authorize or permit any of its or their respective officers, directors,
employees representatives, agents, investment bankers, subsidiaries and
affiliates to, directly or indirectly, solicit, initiate, engage or participate
in discussions or negotiations with, or disclose or afford access to non-public
information concerning the Company and its subsidiaries to or otherwise assist,
encourage or cooperate with or enter into any agreement or understanding with
any person or group (other than Parent and Acquisition or any designees of
Parent and Acquisition) concerning any Third Party Acquisition Proposal;
provided, however, that nothing herein shall prevent the Company Board from
taking and disclosing to the Company's stockholders a position contemplated by
Rules 14d-9 and 14e-2 promulgated under the Exchange Act with regard to any
tender offer. The Company
 
                                      A-19
<PAGE>   105
 
Board shall not withdraw or amend its recommendation of the transactions
contemplated hereby or approve or recommend, or cause the Company to enter into
any agreement with respect to, any Third Party Acquisition Proposal and the
Company shall and shall cause its respective officers, directors, employees,
representatives, agents, investment bankers, subsidiaries and affiliates not to
make or authorize any statement, recommendation or solicitation in support of
any Third Party Acquisition Proposal.
 
     (b) Not withstanding anything to the contrary provided in this Agreement,
the Company Board may participate in negotiations with a Third Party (as defined
below), furnish information (other than documents or reports filed with the
Securities and Exchange Commission) to a Third Party or amend or withdraw its
recommendation of the transactions contemplated hereby or approve or recommend a
Superior Proposal (as defined below), but only after a Third Party shall have
delivered to the Company in writing an unsolicited, bona fide Third Party
Acquisition Proposal that the Company Board by a majority vote determines in its
good faith judgment (after consultation with its principal advisers, including a
financial adviser of nationally recognized reputation), which shall be deemed to
include Cowen & Co.) to be more favorable to the Company's stockholders than the
Merger (a "Superior Proposal") and for which financing, to the extent required,
is then committed or which, in the good faith reasonable judgment of the Company
Board (based on the advice of a financial adviser of nationally recognized
reputation) is reasonably capable of being financed by such Third Party and
which is probable to be consummated in accordance with its terms.
 
     (c) In the event the Company receives a Superior Proposal, the Company will
(i) immediately give written notice to Parent (a "Notice of Superior Proposal")
advising Parent that the Company Board has received an unsolicited bona fide
Superior Proposal, specifying the material terms and conditions of such Superior
Proposal and identifying the person making such Superior Proposal and (ii) give
Parent five business days from its receipt of the Notice of Superior Proposal to
make an offer which the Company Board by a majority vote determines in its good
faith judgment (after consultation with its principal advisers, including a
financial adviser of nationally recognized reputation) to be at least as
favorable to the Company's stockholders as such Superior Proposal, in which
event the Company Board shall accept such offer from Parent unless, within five
business days of the Company's receipt of such offer from Parent, the Company
receives a Third Party Acquisition Proposal that the Company Board, by a
majority vote, determines in its good faith judgment (after consultation with
its principal advisers, including a financial adviser of nationally recognized
reputation, which shall be deemed to include Cowen & Co.) to be more favorable
to the Company's stockholders than such offer from Parent. For the purposes of
this Agreement, "Third Party" means any person, entity or group (which includes
a "person" as such term is defined in Section 13(d)(3) of the Securities
Exchange Act of 1934, as amended) other than Parent, Acquisition or any
affiliate thereof. For the purposes of this Agreement, "Third Party Acquisition
Proposal" means a proposal to the Company by a Third Party for a transaction
that would include any of the following events: (i) the acquisition of the
Company by merger or otherwise by any Third Party; (ii) the acquisition by a
Third Party of more than 50% of the total assets of the Company and its
subsidiaries taken as a whole; or (iii) the acquisition by a Third Party of 50%
or more of the outstanding Common Shares or Preferred Shares.
 
     SECTION 4.5. Comfort Letter. The Company shall use all reasonable efforts
to cause Arthur Andersen LLP to deliver a letter dated not more than five days
prior to the date on which the Proxy Statement shall be mailed to the
stockholders of the Company and addressed to the Company and Parent and their
respective Boards of Directors customary in scope for agreed-upon procedures
letters delivered by independent public accountants in connection with proxy
statements similar to the Proxy Statement. The language in such letter shall in
no event constitute a separate or independent basis on which Parent or
Acquisition can terminate this Agreement or refuse to consummate the
transactions contemplated hereby.
 
     SECTION 4.6. Meeting of Stockholders. The Company shall take all action
necessary in accordance with the DGCL and its Certificate of Incorporation and
bylaws to duly call, give notice of, convene and hold a meeting of its
stockholders as promptly as practicable to consider and vote upon the adoption
and approval of this Agreement and the transactions contemplated hereby. The
stockholder votes required for the adoption and approval of the transactions
contemplated by this Agreement shall be the vote required by the DGCL and the
Company's Certificate of Incorporation and bylaws. The Company will, through its
Board of Directors,
 
                                      A-20
<PAGE>   106
 
recommend to its stockholders approval of such matters, provided, however, the
Company Board may amend or withdraw its recommendation if permitted by Section
4.4 hereof.
 
     SECTION 4.7. Access to Information.
 
     (a) Subject to the provisions of applicable law, between the date hereof
and the Effective Time, the Company will give Parent and its authorized
representatives reasonable access to all employees, plants, offices, warehouses
and other facilities and to all books and records of itself and its
subsidiaries, will permit Parent to make such inspections as Parent may
reasonably require and will cause its officers and those of its subsidiaries to
furnish Parent with such financial and operating data and other information with
respect to the business and properties of the Company and its subsidiaries as
Parent may from time to time reasonably request.
 
     (b) Between the date hereof and the Effective Time, the Company shall
furnish to Parent within 25 business days after the end of each calendar month
(commencing with the month of May) an unaudited balance sheet of the Company as
of the end of the such month and the related statements of earnings,
stockholders' equity (deficit) and within 25 business days after the end of each
calendar quarter cash flows for the quarter then ended, each prepared in
accordance with generally accepted accounting principles in conformity with the
practices consistently applied by such party with respect to its monthly
financial statements. All the foregoing shall be in accordance with the books
and records of the Company and shall fairly present its financial position
(taking into account the differences between the monthly and quarterly
statements prepared by the Company in conformity with its past practices) as of
the last day of the period then ended.
 
     (c) Each of the parties hereto will hold and will cause its consultants and
advisers to hold in confidence all documents and information furnished to it in
connection with the transactions contemplated by this Agreement pursuant to the
terms of that certain Confidentiality Agreement entered into between the Company
and Parent dated March 18, 1998.
 
     SECTION 4.8. Additional Agreements, Reasonable Efforts. Subject to the
terms and conditions herein provided, each of the parties hereto agrees to use
all reasonable efforts to take or cause to be taken all action and to do or
cause to be done all things reasonably necessary, proper or advisable under
applicable laws and regulations to fulfill the conditions to closing under this
Agreement and to consummate and make effective the transactions contemplated by
this Agreement, including, without limitation, (i) cooperating in the
preparation and filing of the Proxy Statement, any filings that may be required
under the HSR Act and any amendments to any thereof, (ii) obtaining consents of
all third parties and Governmental Entities necessary proper or advisable for
the consummation of the transactions contemplated by this Agreement; (iii)
contesting any legal proceeding relating to the Merger and (iv) executing any
additional instruments necessary to consummate the transactions contemplated
hereby. Subject to the terms and conditions of this Agreement, Parent and
Acquisition agree to use all reasonable efforts to cause the Effective Time to
occur as soon as practicable after the meeting of the Company's stockholders
with respect to the Merger. If at any time after the Effective Time any further
action is necessary to carry out the purposes of this Agreement, the proper
officers and directors of each party hereto shall take all such necessary
action.
 
     SECTION 4.9. Employee Benefits.
 
     (a) After the Closing, Parent shall cause the Surviving Corporation to,
honor in accordance with their terms, all employment, severance, consulting and
other compensation contracts between the Company or any of its subsidiaries and
any current or former director, officer or employee thereof, and all provisions
for vested benefits or other vested amounts earned or accrued through the
Closing under any plans described in Section 2.11 of this Agreement (other than
stock option or other plans involving the potential issuance or purchase on the
open market of securities of the Company or of Parent). Parent agrees and will
cause the Surviving Corporation to honor any "change of control" or similar
provisions relating to employees contained in any existing contracts, and all
termination or severance agreements with executive officers identified in
Schedule 2.11 (c) (subject to Section 1.11 hereof) will be honored in accordance
with their terms as of the date hereof.
 
                                      A-21
<PAGE>   107
 
     (b) Parent covenants that for a period of one year after the Closing, it
will cause Surviving Corporation to extend to employees of Surviving Corporation
and its subsidiaries benefit plans which, when viewed in the aggregate, shall be
substantially similar to the Employee Plans in effect with respect to employees
of the Company and its subsidiaries immediately before the Closing.
Notwithstanding the foregoing, nothing in this Agreement, express or implied,
shall (i) obligate the Surviving Corporation or any of its subsidiaries or
Parent to continue to employ any of the employees of the Surviving Corporation
or any of its subsidiaries after the Closing Date (except for those employees
who are parties to employment agreements as disclosed in Schedule 2.11(b) and
then only in accordance with the terms of such employment agreements) or (ii)
operate so as to make any employees of the Company or any of its subsidiaries
third party beneficiaries of any of the provisions of this Agreement (except for
the indemnification obligations under Section 4.11).
 
     SECTION 4.10. Public Announcements. Parent, Acquisition and the Company, as
the case may be, will consult with one another before issuing any press release
or otherwise making any public statements with respect to the transactions
contemplated by this Agreement, including, without limitation, the Merger, and
shall not issue any such press release or make any such public statement prior
to such consultation except as may be required by applicable law or by
obligations pursuant to any listing agreement with the New York Stock Exchange
or NASDAQ National Market System as determined by Parent, Acquisition or the
Company, as the case may be.
 
     SECTION 4.11. Indemnification, Directors' and Officers' Insurance.
 
     (a) After the Effective Time, Parent and the Surviving Corporation jointly
and severally shall indemnify and hold harmless (and shall also advance expenses
as incurred to the fullest extent permitted under applicable law, upon receipt
from such indemnified party of the undertaking to repay such advances
contemplated by Section 145 of the DGCL, to) each person who is now or has been
prior to the date hereof or who becomes prior to the Effective Time an officer
or director of the Company or any of the Company's subsidiaries (the
"Indemnified Persons") against (i) all losses, claims, damages, costs, expenses
(including, without limitation, counsel fees and expenses), settlement payments
(provided Parent and the Surviving Corporation have approved such settlement,
which approval shall not be unreasonably withheld) or liabilities arising out of
or in connection with any claim, demand, action, suit, proceeding or
investigation (a "Claim") based in whole or in part on or arising in whole or in
part out of the fact that such person is or was an officer or director of the
Company or any of its subsidiaries whether or not pertaining to any matter
existing or occurring at or prior to the Effective Time and whether or not
asserted or claimed prior to or at or after the Effective Time ("Indemnified
Liabilities") to the fullest extent permitted by applicable law and (ii) all
Indemnified Liabilities based in whole or in part on or arising in whole or in
part out of or pertaining to this Agreement or the transactions contemplated
hereby, in each case to the fullest extent required or permitted under
applicable law or under the Surviving Corporation's Certificate of Incorporation
or bylaws. The parties hereto intend, to the extent not prohibited by applicable
law, that the indemnification provided for in this Section 4.11 shall apply
without limitation to negligent acts or omissions by an Indemnified Person.
Parent hereby guarantees the payment and performance of the Surviving
Corporation's obligations in this Section 4.11. Each Indemnified Person is
intended to be a third party beneficiary of this Section 4.11 and may
specifically enforce its terms. This Section 4.11 shall not limit or otherwise
adversely affect any rights any Indemnified Person may have under any agreement
with the Company or under the Company's Certificate of Incorporation or Bylaws.
 
     (b) Any Indemnified Party wishing to claim indemnification under this
Section 4.11, upon learning of any such Claim, shall notify Parent and the
Surviving Corporation (although the failure so to notify Parent and the
Surviving Corporation shall not relieve Parent and the Surviving Corporation
from any liability which Parent and the Surviving Corporation may have under
this Section 4.11 except to the extent such failure prejudices Parent and the
Surviving Corporation), and shall deliver to Parent and the Surviving
Corporation the undertaking as contemplated by Section 145 of the DGCL. The
Indemnified Parties as a group shall retain one law firm (in addition to local
counsel) to represent them with respect to each such matter unless (i) there is,
under applicable standards of professional conduct (as determined by counsel to
the Indemnified Parties), a conflict or potential conflict between the positions
of any two or more Indemnified Parties, or (ii) an Indemnified Party reasonably
concludes (based upon advice of counsel) that there may be legal defenses
available to the Indemnified Party that are different from or in addition to
those available to the other
 
                                      A-22
<PAGE>   108
 
Indemnified Parties, in which events, such additional counsel as may be required
may be retained by the Indemnified Parties.
 
     (c) Parent shall cause the Surviving Corporation to maintain in effect for
not less than six (6) years from the Effective Time the policies of the
directors' and officers' liability and fiduciary insurance most recently
maintained by the Company with aggregate liability coverage not less than the
coverage provided by the insurance most recently maintained by the Company
(provided that the Surviving Corporation may substitute therefor policies of at
least the same coverage containing terms and conditions which are no less
advantageous to the beneficiaries thereof so long as such substitution does not
result in gaps or lapses in coverage) with respect to matters occurring prior to
the Effective Time; provided, however, that in satisfying its obligation under
this Section, the Surviving Corporation shall not be obligated to pay premiums
in excess of 150% of the amount per annum incurred by the Company in the twelve
months ended December 31, 1997 with respect to such insurance, which amount has
been disclosed to Parent.
 
     (d) In the event the Surviving Corporation or its successor (i) is
consolidated with or merges into another person and is not the continuing or
surviving corporation or entity of such consolidation or merger or (ii)
transfers all or substantially all of its properties and assets to any other
person in a single transaction or a series of related transactions, then in each
such case Parent shall make or cause to be made proper provision so that the
successor or transferee of the Surviving Corporation shall comply in all
material respect with the terms of this Section 4.11.
 
     SECTION 4.12. Notification of Certain Matters. The Company shall give
prompt notice to Parent and Acquisition, and Parent and Acquisition shall give
prompt notice to the Company, of (i) the occurrence or nonoccurrence of any
event the occurrence or nonoccurrence of which would be likely to cause any
representation or warranty contained in this Agreement to be untrue or
inaccurate in any material respect at or prior to the Effective Time, and (ii)
any material failure of the Company, Parent or Acquisition, 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 the delivery of any
notice pursuant to this Section 4.12 shall not cure such breach or
non-compliance or limit or otherwise affect the remedies available hereunder to
the party receiving such notice.
 
     SECTION 4.13. Information Supplied. None of the information supplied or to
be supplied by Parent or Acquisition specifically for inclusion or incorporation
by reference to the Proxy Statement will, at the date mailed to stockholders and
at the times of the meeting or meetings of stockholders of the Company to be
held in connection with the Merger, 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 therein in light of the circumstances
under which they are made not misleading.
 
     SECTION 4.14. GTI Tax Matters. With respect to any income tax Return
required to be filed by Company and its subsidiaries from the date of this
Agreement through the Effective Time, Company shall provide to Parent and its
authorized representatives with copies of such completed Return at least fifteen
(15) business days prior to the due date (or extended due date if an extension
has been obtained) for the filing of such Return. Parent and its authorized
representatives shall have the right to review such Return prior to the filing
of such Return. Company and Parent agree to consult and resolve in good faith
any issues arising as a result of the review of such Return by Parent and its
authorized representatives.

May 26, 1998
 
Special Committee of the Board of Directors
  and the Board of Directors
GTI Corporation
9715 Business Park Drive
San Diego, CA 92131
 
Gentlemen:
 
You have requested our opinion as investment bankers as to the fairness, from a
financial point of view, to the holders of the outstanding shares of Common
Stock, par value $0.04 per share ("GTI Common Stock"), of GTI Corporation, a
Delaware corporation (the "Company"), of the financial terms of the Transaction.
For the purposes of this opinion, the "Transaction" means the merger described
below pursuant to the Agreement and Plan of Merger among the Company, Technitrol
International, Inc., a Delaware corporation ("Parent"), and Technitrol
Acquisition, Inc., a Delaware corporation and a wholly owned subsidiary of
Parent ("Acquisition"), to be dated as of May 26, 1998 (the "Agreement").
 
The Agreement provides for the merger of Acquisition with and into the Company,
subject to the terms and conditions thereof and as more specifically set forth
therein. Upon effectiveness of the Transaction, among other things, (i) each
issued and outstanding share of GTI Common Stock (other than Company Dissenting
Shares, as defined in the Agreement, shares held in the Company's treasury or by
any of the Company's subsidiaries and shares then owned by Parent or Acquisition
or any other subsidiary of Parent) will be converted into the right to receive
$3.10 in cash, without interest and (ii) each issued and outstanding share of
the Company's First Series Cumulative Convertible Preferred Stock, par value
$1.00 per share ("Preferred Stock"), will be converted into the right to receive
the product of 234.314 multiplied by $3.10.
 
In the ordinary course of its services, Cowen & Company ("Cowen") is regularly
engaged in the valuation and pricing of business and their securities and in
advising corporate securities issuers on related matters.
 
In arriving at our opinion, Cowen has, among other things:
 
          (1)  reviewed the Company's combined and consolidated financial
     statements for the fiscal years ended December 31, 1995 through December
     31, 1997, unaudited financial statements for the fiscal quarter ended March
     31, 1998, certain publicly available filings with the Securities and
     Exchange Commission and certain other relevant financial and operating data
     of the Company;
 
          (2)  reviewed the May 25, 1998 draft of the Agreement provided to us
     by management of the Company;
 
          (3) held meetings and discussions with management and senior personnel
     of the Company to discuss the business, operations, historical financial
     results and future prospects of the Company;
 
          (4) reviewed financial projections furnished to us by the management
     of the Company, including, among other things, the capital structure,
     sales, operating income, net income, cash flow, capital requirements and
     other data of the Company we deemed relevant;
 
          (5) reviewed the operating and financial results of the Company over
     the last three fiscal years and compared its results with the operating and
     financial results of certain other publicly traded companies which we
     deemed relevant;
 
                                       B-1
<PAGE>   119
 
          (6) reviewed the public market valuation and trading multiples of the
     Company, and compared the Company's trading multiples to the trading
     multiples of certain other publicly traded companies which we deemed
     relevant;
 
          (7) reviewed the historical prices and trading activity of GTI Common
     Stock from May 22, 1997 to May 22, 1998 and from May 22, 1995 to May 22,
     1998 and compared the price performance of GTI Common Stock to the stock
     price performance of certain other publicly traded companies which we
     deemed relevant over the period from May 22, 1997 to May 22, 1998;
 
          (8) compared the financial terms of the Transaction with the financial
     terms of the acquisitions of certain other companies which we deemed
     relevant, including a comparison of the premiums paid in the Transaction
     with the premiums paid in those other acquisitions; and
 
          (9) conducted such other studies, analysis, inquiries and
     investigations as we deemed appropriate.
 
     At the request of the Company, Cowen solicited third party indications of
     interest in acquiring all or substantially all of the stock or assets of
     the Company.
 
On May 22, 1998, the closing price of GTI Common Stock in the last transaction
reported by the National Association of Securities Dealers, Inc. Automated
Quotation/National Market System ("Nasdaq/NMS") was $2.75.
 
In rendering our opinion, we relied upon the Company's management with respect
to the accuracy and completeness of the financial and other information
furnished to us as described above. With respect to the financial projections
furnished to us by management of the Company, we have assumed, with your
consent, the attainability of the financial results therein and that they have
been reasonably prepared on bases reflecting the best currently available
estimates and judgments of the Company's management as to the future financial
performance of the Company. We have not assumed any responsibility for
independent verification of such information, including financial information,
nor have we made an independent evaluation or appraisal of any of the properties
or assets of the Company. With respect to all legal matters relating to the
Company, Parent and the Transaction, we have relied on the advice of legal
counsel of the Company. We render no opinion with respect to such matters.
 
Our opinion is necessarily based on general economic, market, financial and
other conditions as they exist on, and can be evaluated as of, the date hereof,
as well as the information currently available to us. It should be understood
that, although subsequent developments may affect our opinion, we do not have
any obligation to update, revise or reaffirm our opinion. Our opinion does not
constitute a recommendation to any stockholder as to how such stockholder should
vote on the proposed Transaction. Our opinion is limited to the fairness, from a
financial point of view, of the financial terms of the Transaction to the
holders of GTI Common Stock (other than Parent and its subsidiaries and
affiliates). We express no opinion with respect to any other reasons, legal,
business or otherwise, that may support the decision of the Special Committee of
the Board of Directors to recommend to the Board of Directors the approval of,
the decision of the Board of Directors to approve, or the Company's decision to
enter into, the Agreement.
 
For purposes of rendering our opinion we have assumed, in all respects material
to our analysis, that the representations and warranties of each party contained
in the Agreement are true and correct, that each party will perform all of the
covenants and agreements required to be performed by it under the Agreement and
that all conditions to the consummation of the Transaction will be satisfied
without waiver thereof. We have also assumed that all governmental, regulatory
or other consents and approvals contemplated by the Agreement will be obtained
and that in the course of obtaining any of those consents no restrictions will
be imposed or waivers made that would have a material adverse effect on the
contemplated benefits of the Transaction.
 
We have also assumed, with your consent, that prior to the effectiveness of the
Transaction, each issued and outstanding share of Preferred Stock will be
converted into 234.314 shares of GTI Common Stock. We express no opinion, nor
have we conducted any analysis, with respect to a transaction that does not
contemplate the aforementioned conversion of all outstanding Preferred Stock
shares into GTI Common
 
                                       B-2
<PAGE>   120
 
Stock shares. We also express no opinion as to the consideration that could have
been received by the holders of the Preferred Stock absent the conversion.
 
We have acted as financial advisor to the Special Committee of the Board of
Directors of the Company in connection with the Transaction and will receive a
fee for our services, including the rendering of this opinion, a significant
portion of which is contingent upon the consummation of the Transaction.
 
On the basis of our review and analysis, as described above, and subject to the
limitations and assumptions set forth herein, it is our opinion as investment
bankers that, as of the date hereof, the financial terms of the Transaction are
fair, from a financial point of view, to the holders of GTI Common Stock other
than Parent and its subsidiaries and affiliates.
 
Very truly yours,
 
/s/ COWEN & COMPANY

                                                        APPRAISAL RIGHTS STATUTE
 
                        DELAWARE GENERAL CORPORATION LAW
 
     SECTION 262  APPRAISAL RIGHTS -- (a) Any stockholder of a corporation of
this State who holds shares of stock on the date of the making of a demand
pursuant to subsection (d) of this section with respect to such shares, who
continuously holds such shares through the effective date of the merger or
consolidation, who has otherwise complied with subsection (d) of this section
and who has neither voted in favor of the merger or consolidation nor consented
thereto in writing pursuant to Section 228 of this title shall be entitled to an
appraisal by the Court of Chancery of the fair value of the stockholder's shares
of stock under the circumstances described in subsections (b) and (c) of this
section. As used in this section, the word "stockholder" means a holder of
record of stock in a stock corporation and also a member of record of a nonstock
corporation; the words "stock" and "share" mean and include what is ordinarily
meant by those words and also membership or membership interest of a member of a
nonstock corporation; and the words "depository receipt" mean a receipt or other
instrument issued by a depository representing an interest in one or more
shares, or fractions thereof, solely of stock of a corporation, which stock is
deposited with the depository.
 
     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to Section 251 (other than a merger effected pursuant to
Section 251(g) of this title), Section 252, Section 254, Section 257, Section
258, Section 263 or Section 264 of this title:
 
          (1) Provided, however, that no appraisal rights under this section
     shall be available for the shares of any class or series of stock, which
     stock, or depository receipts in respect thereof, at the record date fixed
     to determine the stockholders entitled to receive notice of and to vote at
     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of record by more than 2,000 holders; and further provided that no
     appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the stockholders of the surviving corporation
     as provided in subsection (f) of Section 251 of this title.
 
          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent corporation if the holders thereof are required
     by the terms of an agreement of merger or consolidation pursuant to
     Sections 251, 252, 254, 257, 258, 263 and 264 of this title to accept for
     such stock anything except:
 
             a. Shares of stock of the corporation surviving or resulting from
        such merger or consolidation, or depository receipts in respect thereof;
 
             b. Shares of stock of any other corporation, or depository receipts
        in respect thereof, which shares of stock (or depository receipts in
        respect thereof) or depository receipts at the effective date of the
        merger or consolidation will be either listed on a national securities
        exchange or designated as a national market system security on an
        interdealer quotation system by the National Association of Securities
        Dealers, Inc. or held of record by more than 2,000 holders;
 
             c. Cash in lieu of fractional shares or fractional depository
        receipts described in the foregoing subparagraphs a. and b. of this
        paragraph; or
 
             d. Any combination of the shares of stock, depository receipts and
        cash in lieu of fractional shares or fractional depository receipts
        described in the foregoing subparagraphs a., b. and c. of this
        paragraph.
 
          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under Section 253 of this title is not owned by
     the parent corporation immediately prior to the merger, appraisal rights
     shall be available for the shares of the subsidiary Delaware corporation.
 
                                       C-1
<PAGE>   122
 
     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.
 
     (d) Appraisal rights shall be perfected as follows:
 
          (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting, shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares for which appraisal
     rights are available pursuant to subsections (b) or (c) hereof that
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section. Each stockholder electing to demand the appraisal of his shares
     shall deliver to the corporation, before the taking of the vote on the
     merger or consolidation, a written demand for appraisal of his shares. Such
     demand will be sufficient if it reasonably informs the corporation of the
     identity of the stockholder and that the stockholder intends thereby to
     demand the appraisal of his shares. A proxy or vote against the merger or
     consolidation shall not constitute such a demand. A stockholder electing to
     take such action must do so by a separate written demand as herein
     provided. Within 10 days after the effective date of such merger or
     consolidation, the surviving or resulting corporation shall notify each
     stockholder of each constituent corporation who has complied with this
     subsection and has not voted in favor of or consented to the merger or
     consolidation of the date that the merger or consolidation has become
     effective; or
 
          (2) If the merger or consolidation was approved pursuant to Section
     228 or Section 253 of this title, each constituent corporation, either
     before the effective date of the merger or consolidation or within ten days
     thereafter, shall notify each of the holders of any class or series of
     stock of such constituent corporation who are entitled to appraisal rights
     of the approval of the merger or consolidation and that appraisal rights
     are available for any or all shares of such class or series of stock of
     such constituent corporation, and shall include in such notice a copy of
     this section; provided that, if the notice is given on or after the
     effective date of the merger or consolidation, such notice shall be given
     by the surviving or resulting corporation to all such holders of any class
     or series of stock of a constituent corporation that are entitled to
     appraisal rights. Such notice may, and, if given on or after the effective
     date of the merger or consolidation, shall, also notify such stockholders
     of the effective date of the merger or consolidation. Any stockholder
     entitled to appraisal rights may, within 20 days after the date of mailing
     of such notice, demand in writing from the surviving or resulting
     corporation the appraisal of such holder's shares. Such demand will be
     sufficient if it reasonably informs the corporation of the identity of the
     stockholder and that the stockholder intends thereby to demand the
     appraisal of such holder's shares. If such notice did not notify
     stockholders of the effective date of the merger or consolidation, either
     (i) each such constituent corporation shall send a second notice before the
     effective date of the merger or consolidation notifying each of the holders
     of any class or series of stock of such constituent corporation that are
     entitled to appraisal rights of the effective date of the merger or
     consolidation or (ii) the surviving or resulting corporation shall send
     such a second notice to all such holders on or within 10 days after such
     effective date; provided, however, that if such second notice is sent more
     than 20 days following the sending of the first notice, such second notice
     need only be sent to each stockholder who is entitled to appraisal rights
     and who has demanded appraisal of such holder's shares in accordance with
     this subsection. An affidavit of the secretary or assistant secretary or of
     the transfer agent of the corporation that is required to give either
     notice that such notice has been given shall, in the absence of fraud, be
     prima facie evidence of the facts stated therein. For purposes of
     determining the stockholders entitled to receive either notice, each
     constituent corporation may fix, in advance, a record date that shall be
     not more than 10 days prior to the date the notice is given, provided, that
     if the notice is given on or after the effective date of the merger or
     consolidation, the record date shall be such effective date. If no record
     date is fixed and the notice is given prior to the effective date, the
     record date shall be the close of business on the day next preceding the
     day on which the notice is given.
 
                                       C-2
<PAGE>   123
 
     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw his demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
his written request for such a statement is received by the surviving or
resulting corporation or within 10 days after expiration of the period for
delivery of demands for appraisal under section (d) hereof, whichever is later.
 
     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.
 
     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.
 
     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted his
certificates of stock to the Register in Chancery, if such is required, may
participate fully in all proceedings until it is finally determined that he is
not entitled to appraisal rights under this section.
 
     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
                                       C-3
<PAGE>   124
 
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.
 
     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.
 
     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection (d)
of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in
subsection (e) of this section or thereafter with the written approval of the
corporation, then the right of such stockholder to an appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.
 
     (i) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation. (Last amended by Ch.
120, L.'97, eff. 7-1-97.)
