ITEM 4.  THE SOLICITATION OR RECOMMENDATION.

     (a) Recommendation of the Board of Directors

     The Board has by a unanimous vote of those present at the meeting: (i)
approved the Merger Agreement, a copy of which is filed as Exhibit 1 to this
Schedule 14D-9 and is incorporated herein by reference, and the transactions
contemplated thereby, (ii) determined that each of the Offer and the Merger is
fair to, and in the best interests of, the holders of the Shares, and (iii)
declared that the Offer and Merger are advisable. The Board, by a unanimous vote
of those present at the meeting, recommends that all holders of Shares accept
the Offer and tender their Shares pursuant to the Offer.

     A letter to the shareholders of the Company communicating the Board's
recommendation is filed as Exhibit 6 hereto and is incorporated herein by
reference.

     (b) Background of the Transaction

     On August 14, 1998, the Company entered into a merger agreement with McLeod
Russel Holdings, PLC ("McLeod Russel") providing for the acquisition of all of
the outstanding stock of the Company at a price of $7.27 per share. On October
15, 1998, the Company and McLeod Russel announced that they had mutually
terminated the merger agreement. On November 4, 1998, the Company announced that
the Board had determined not to pursue a sale of the Company pending year-end
results but that the Board would consider unsolicited expressions of interest it
might receive from third parties.

     On November 10, 1998, Sal Giordano, Jr., Vice Chairman and Chief Executive
Officer of Parent, sent a letter to Steven L. Schneider, President and Chief
Executive Officer of the Company, indicating Parent's possible interest in
acquiring the Company. The Company's financial adviser, Harris Williams & Co.
("Harris Williams") communicated to Parent that the Company was reviewing its
alternatives and would respond in due course.

     On February 3, 1999, the Company announced its results for the 1998 fiscal
year. On that same day Mr. Giordano sent another letter to Mr. Schneider and the
Board reiterating Parent's interest in acquiring the Company.

     On February 5, 1999, the Board met and determined that, in light of
prevailing market conditions, the general economic outlook of the indoor air
quality equipment market and the Company's recent stock performance since the
termination of the proposed transaction with McLeod Russel, it was advisable and
in the best interests of the Company and its shareholders to pursue strategic
alternatives, including the possible sale of the Company. At the February 5,
1999 meeting, the Board authorized the engagement of Harris Williams to act as
the Company's investment bankers and to assist and advise the Board regarding
financial

                                        2
<PAGE>   4

matters. The Company formally engaged Harris Williams in such capacity on
February 8, 1999. The Company engaged Smith Helms Mulliss & Moore, L.L.P.
("Smith Helms") to act as legal counsel. These decisions were announced in a
press release issued on March 17, 1999, as was the fact that the Company was
pursuing strategic alternatives, including the possible sale of the Company.

     On February 25, 1999, Parent and the Company signed a confidentiality
agreement.

     On April 7, 1999, the Board formed a valuation committee (the "Committee")
to assist the Board in analyzing offers presented by the Company and to assist
in the valuation of such offers. The Board appointed F. Trent Hill, Jr. and
Seddon Goode, Jr., to the Committee and designated Mr. Hill as chairman.

     The Committee determined that Harris Williams should begin to solicit
indications of value from prospective purchasers. Harris Williams was instructed
to forward to the Committee any indications of value it received.

     By April 16, 1999, Harris Williams had contacted approximately 174
prospective purchasers. Of these prospective purchasers, approximately 58 were
sent a confidential information memorandum prepared by Harris Williams (the
"Confidential Memorandum"). Each recipient signed a confidentiality agreement
prior to receipt of a Confidential Memorandum. Harris Williams continually
apprised the Committee of the indications of interest received.

     The Company received eleven indications of interest. Of these eleven
indications of interest, seven, including Parent's, were at a value deemed by
the Committee to be worthy of pursuing. The Committee instructed Harris Williams
to work with these prospective purchasers and to provide them with requested
diligence materials. These seven groups were invited to visit the Company's
Sanford, North Carolina facility (the "Company Facility").

     From April 28 to May 13, 1999, five of the invited parties, including
Parent, visited the Company Facility. During those visits, the prospective
purchasers met with representatives of Harris Williams and Company management
and management presentations were given by Mr. Schneider, Calvin J. Monsma, the
Vice President and the Chief Financial Officer of the Company, and other members
of Company management. The Committee was briefed on these visits by Harris
Williams. These prospective purchasers were evaluated by Harris Williams and the
Committee for their level of interest, financial strength, ability to consummate
a transaction and potential synergy with the Company.

     The Board was apprised of the status of the communications with prospective
purchasers at meetings of the Board held on April 29, 1999, May 11, 1999 and May
21, 1999.

     On May 11, 1999 and following their visit to the Company Facility, Parent
and TM Capital Corp. ("TM Capital"), the financial advisor to Parent, requested
to visit the facility of Envirco Corporation, a wholly owned subsidiary of the
Company ("Envirco"), in Albuquerque, New Mexico (the "Envirco Facility").
Invitations to visit the Envirco Facility were extended to the other four
prospective purchasers who had visited the Company Facility.

     In order to determine the level of interest of the prospective purchasers,
a bid solicitation letter was sent out by Harris Williams on May 12, 1999. The
solicitation letter requested that bids be submitted by June 2, 1999.

     On May 19, 1999, Parent and TM Capital visited the Envirco Facility
accompanied by Mr. Schneider and a representative of Harris Williams. None of
the other prospective purchasers visited the Envirco Facility.

     On May 24, 1999, Parent visited the Company's data room in Raleigh, North
Carolina. Two other prospective purchasers also visited the data room prior to
the bid deadline.

     By the June 2, 1999 deadline the Company received bids from five
prospective purchasers.

     On June 4, 1999, the Committee met to be briefed on the bids received.
Harris Williams described the bids and noted that of the five bids, two bids,
including that of Parent, were deemed to be more favorable than the other three.
The Committee focused primarily on these two bids. Parent's initial bid was a
purchase price

                                        3
<PAGE>   5

based on $5.50 per Share and the other bidder's bid (the "Second Bidder") was a
purchase price based on $5.65 per Share.

     At the Board meeting on June 7, 1999, the Board met to be updated on the
progress in the Company's pursuit of strategic alternatives. A representative of
Smith Helms advised the Board as to its fiduciary duties in regard to pursuing
strategic alternatives in general and with regard to the duties of the Board
should they decide to sell the Company. Harris Williams then reviewed the five
bids received. The Board focused on the bids of Parent and the Second Bidder.
The projected timetable for completing a transaction with each of the bidders
was discussed by the Board as were various contingencies that could affect the
likelihood of completing a transaction with each of the two prospective
purchasers. In particular, Parent's bid did not contain a financing contingency,
while the Second Bidder's bid contained such a provision. The Board noted that
Parent was the more likely of the two bidders to be able to successfully
complete the transaction, and the forecasted time of completion was
significantly shorter than that for the Second Bidder. The Board determined that
the terms and conditions of the Second Bidder's proposal were not as favorable
as that of Parent and that the likelihood of completing such a transaction with
the Second Bidder was less certain. The Board authorized Harris Williams to
continue negotiations with Parent.

     On June 8, 1999, Harris Williams contacted Parent in an attempt to increase
the amount of consideration in Parent's offer.

     On June 9, 1999, Parent informed Harris Williams that, pending the results
of due diligence, it would increase its proposed offer to $5.65 per Share.

     On June 9, 1999, Harris Williams approached the Second Bidder and informed
them that they were not the favored offer. The Second Bidder did not increase
its offer price or alter the terms of its bid.

     On June 9, 1999, the Board decided based on the unanimous vote of the
directors present to authorize Smith Helms and Harris Williams to negotiate a
definitive purchase agreement with Parent. The Committee was asked to oversee
the negotiations and to represent the Board in regard to such negotiations.

     From June 9 to July 9, 1999, TM Capital together with representatives of
Parent, conducted further legal and financial due diligence investigations of
the Company. During this same time period, Smith Helms, Harris Williams, TM
Capital and Skadden, Arps, Slate, Meagher & Flom LLP, Parent's legal advisor,
began to negotiate the terms of the Merger Agreement.

     On the afternoon of July 8, 1999, the Company was notified that, based on
the results of due diligence performed by Parent, Parent was reducing the price
per share it was proposing to pay to $5.50.

     On July 9, 1999 the members of the Board were contacted regarding their
views on the status of the negotiations. A meeting of the Board was scheduled
for Monday, July 12, 1999. On July 9, 1999 representatives of the Company and
Parent and their respective financial advisors discussed the rationale for
lowering the proposed purchase price, including Parent's assertions that, based
on its due diligence, the financial condition of the Company, its current sales
orders and future prospects supported a price of $5.50 per share. During this
discussion, Parent rejected proposals to increase the proposed purchase price.
After the close of business on Friday, July 9, 1999 the Company received a
letter from Parent describing the terms of its $5.50 per share offer.

     On July 12, 1999, a special meeting of the Board was held to discuss the
status of the discussions with Parent. Following a presentation of the proposed
transaction by Harris Williams and a discussion of the terms of the Merger
Agreement and related documents by Smith Helms, the Board requested that Harris
Williams contact TM Capital to attempt to increase the amount of consideration
in the Offer. The meeting was adjourned to continue negotiations with the
Parent. At the meeting, the Board was informed the maximum price Parent was
willing to pay was $5.50 per share. Harris Williams made a financial
presentation to the Board and delivered its opinion to the effect that, as of
such date, the cash consideration to be received in the Offer and the Merger by
the holders of Shares was fair, from a financial point of view, to such holders.
Smith Helms then advised the Board with respect to certain legal matters,
including their fiduciary obligations in

                                        4
<PAGE>   6

connection with the sale of the Company. The Board then approved the terms of
the Offer and the Merger Agreement.

     Following the Board's meeting, the Merger Agreement was finalized and
executed by the parties on July 12, 1999. The Company and Parent each announced
the execution of the Merger Agreement and the impending Offer in press releases
issued on July 13, 1999.

     (c) Reasons for the Recommendation

     In reaching its conclusions and recommendations described above, the Board
considered a number of factors, including the following:

          (i) The terms and conditions of the Merger Agreement;

          (ii) The financial condition, results of operations, business and
     prospects of the Company;

          (iii) The historical trading price of the Common Stock, and the
     expected trading prices for the foreseeable future;

          (iv) Conditions in the air cleaning equipment industry generally;

          (v) The fairness opinion of Harris Williams dated July 12, 1999 (the
     "Fairness Opinion"), to the effect that, as of the date of the opinion, the
     consideration to be received by the holders of Shares pursuant to the Offer
     and the Merger is fair from a financial point of view to such shareholders.
     The full text of the Fairness Opinion which sets forth the procedures
     followed, the factors considered and the assumptions made by Harris
     Williams is attached hereto as Annex II, is filed as Exhibit 7 to this
     Schedule 14D-9, and is incorporated herein by reference. SHAREHOLDERS OF
     THE COMPANY ARE URGED TO READ THE FAIRNESS OPINION CAREFULLY;

          (vi) The interest of other bidders in acquiring the Company, the price
     and other terms and conditions contained in the expressions of intent of
     such other bidders and the timing and likelihood of actually consummating a
     transaction with any such potential bidders.

          (vii) The representation of Parent and Purchaser that they expect to
     have available to them funds sufficient to satisfy all of their respective
     obligations under the Offer and the Merger Agreement, and the fact that the
     Offer is not subject to a financing condition;

          (viii) The provisions of the Merger Agreement that prohibit the
     Company or any of its affiliates from continuing, participating in or
     initiating discussions or negotiations with, or provide any information to,
     any person or group concerning any Acquisition Proposal (as such term is
     defined in Section 1.1 of the Merger Agreement), and that the Company may
     not, except as permitted by the Merger Agreement, withdraw or modify, or
     propose to withdraw or modify, its position with respect to the Offer or
     the Merger or approve or recommend, or propose to approve or recommend any
     Acquisition Proposal, or enter into any agreement with respect to any
     Acquisition Proposal and that the Company will immediately cease any
     existing activities, discussions or negotiations with any parties conducted
     prior to the execution of the Merger Agreement but that the Company may
     furnish information concerning its business, properties or assets to any
     corporation, partnership, person or other entity or group pursuant to
     appropriate confidentiality agreements, and may negotiate and participate
     in discussions and negotiations with such entity or group concerning an
     Acquisition Proposal if such entity or group has submitted a Superior
     Proposal (as such term is defined in Section 1.1 of the Merger Agreement)
     and such action is required to discharge the Board's fiduciary duties to
     the Company's shareholders under applicable law. In addition, the Board may
     withdraw or modify its approval or recommendation of the Offer, the Merger
     Agreement or the Merger, approve or recommend a Superior Proposal, or enter
     into an agreement with respect to a Superior Proposal if certain conditions
     are met.

          (ix) The Stock Option Agreement to be executed by the Company which
     would require the Company, in the event that the Merger Agreement is
     terminated under certain circumstances, to grant an option to Parent to
     purchase 19.9% of the Shares at a price of $5.50 per Share, which the Board
     recognized would potentially foreclose competing offers at approximately
     the same price level as, or at
                                        5
<PAGE>   7

     slightly higher levels than, the Offer, but, based in part on the advice of
     Harris Williams, was very similar to stock option agreements required and
     executed in transactions of similar size and should not deter competing
     offers at price levels significantly higher than the Offer;

          (x) The Shareholder Agreements, pursuant to which each of the
     directors of the Company have agreed to, among other things, (a) tender
     certain Shares to Purchaser beneficially owned by such directors (totaling
     719,764 Shares in the aggregate) which would result in Parent and its
     affiliates, owning approximately 10.1% of the outstanding Shares, (b) grant
     to Parent an option exercisable under certain circumstances to purchase the
     Shares beneficially owned by such directors, and (c) vote all shares owned
     by such directors in favor of the Merger Agreement and against other
     acquisition proposals, which the Board recognizes would potentially
     foreclose competing offers at approximately the same price level as, or at
     slightly higher levels than, the Offer, but based in part on advice of
     Harris Williams, was very similar to shareholder agreements required and
     executed in transactions of similar size and should not deter competing
     offers at price levels significantly higher than the Offer;

          (xi) The provisions of the Merger Agreement that require the Company
     to pay to Parent a termination fee of $2,000,000 if the Merger Agreement is
     terminated under certain circumstances, which the Board recognized would
     potentially foreclose competing offers at approximately the same price
     level as, or at slightly higher levels than, the Offer, but, based in part
     on the advice of Harris Williams, was well within the range of termination
     fees payable in transactions of similar size and should not deter competing
     offers at price levels significantly higher than the Offer;

          (xii) The fact that many of the other prospective purchasers with whom
     the Company had been in contact did not submit proposals after reviewing
     the Confidential Memorandum and/or other informational materials about the
     Company, and that those proposals which were submitted were not as
     favorable to the best interests of the shareholders of the Company as was
     the proposal submitted by Parent; and

          (xiii) The possible alternatives to the Offer and the Merger.

     The Board did not assign relative weights to the foregoing factors or
determine that any factor was of particular importance. Rather, the Board viewed
their position and recommendations as being based on the totality of the
information presented to and considered by them. In addition, individual members
of the Board may have given different weight to different factors.

     The Board recognized that, while the consummation of the Offer gives the
shareholders of the Company the opportunity to realize a premium over the prices
at which the Common Stock was traded prior to the public announcement of the
Offer and the Merger, tendering Shares in the Offer would eliminate the
opportunity for shareholders of the Company to participate in the future growth
and profits of the Company.

     It is expected that, if the Shares are not to be purchased by Purchaser in
accordance with the terms of the Offer, the Company's current management, under
the general direction of the Board, would continue to manage the Company as an
ongoing business in accordance with the Company's current long-term strategic
plan.

ITEM 5.  PERSONS RETAINED, EMPLOYED OR TO BE COMPENSATED.

     The Company retained Harris Williams as its financial advisor in connection
with the Offer and the Merger. Pursuant to the terms of Harris Williams'
engagement, the Company has agreed to pay Harris Williams a transaction fee
based on the total consideration payable in connection with the Offer and the
Merger. The fee payable to Harris Williams is currently estimated to be
approximately $825,000 (which includes retainers paid but excludes reimbursable
expenses). In addition, the Company has agreed to reimburse Harris Williams for

     Except as set forth above, neither the Company nor any person acting on its
behalf currently intends to employ, retain or compensate any other person to

behalf with respect to the Offer.

ITEM 6.  RECENT TRANSACTIONS AND INTENT WITH RESPECT TO SECURITIES.

     (a) No transactions in the Common Stock have been affected during the past
60 days by the Company, or to the best of the Company's knowledge by any

the Company.

     (b) To the best knowledge of the Company, all of the Company's executive
officers, directors and affiliates that own shares of Common Stock currently
intend to tender their Shares pursuant to the Offer, except to the extent that
the tender of such Shares might subject such persons to liability under the
provisions of Section 16(b) of the Exchange Act.

ITEM 7.  CERTAIN NEGOTIATIONS AND TRANSACTIONS BY THE SUBJECT COMPANY.

     (a) Except as set forth in this Schedule 14D-9, the Company is not engaged
in any negotiation in response to the Offer which relates to or would result in
(i) an extraordinary transaction, such as a merger or reorganization, involving
the Company or any of its subsidiaries; (ii) a purchase, sale or transfer of a
material amount of assets by the Company or any of its subsidiaries; (iii) a
tender offer for or other acquisition of securities by or of the Company; or
(iv) any material change in the present capitalization or dividend policy of the
Company.

     (b) Except as set forth in Item 3(b)(1) and (2) and Item 4 herein, there
are no transactions, Board resolutions, agreements in principle or signed
contracts in response to the Offer which relate to or would result in one or
more of the matters referred to in Item 7(a) above.

ITEM 8.  ADDITIONAL INFORMATION TO BE FURNISHED.

     (a) Subchapter 25E Rights

     Holders of Common Stock have certain rights ("Subchapter 25E Rights") under
Subchapter 25E of the PBCL which will become applicable prior to the Effective
Time of the Merger (as defined in Section 3.3 of the Merger Agreement) in the
event that Purchaser (or a group of related persons, or any other person or
group of related persons) were to acquire Shares representing at least 20% of
the voting power of the Company, in connection with the Offer or otherwise (a
"Control Transaction"). In such event, shareholders of the Company would have
the right to demand "fair value" of such shareholders' Shares and to be paid
such fair value upon compliance with the requirements of Subchapter 25E. Under
Subchapter 25E, "fair value" may not be less than the highest price per Share
paid by the controlling person or group at any time during the 90-day period
ending on and including the date of the Control Transaction, plus an increment,
if any, representing any value, including, without limitation, any proportion of
value payable for acquisition of control of the Company, that may not be
reflected in such price. Purchaser states in its Schedule 14D-1 that it believes
that the Offer Price represents fair value of the Shares within the meaning of
Subchapter 25E. Subchapter 25E Rights would attach immediately upon consummation
of a Control Transaction and require that any shareholder seeking such appraisal
must make a demand for fair value within a reasonable time after the notice to
shareholders that a Control Transaction has occurred is given by the controlling
person or group in accordance with Subchapter 25E, which time period may be
specified in such notice, as well as comply with the other procedures of
Subchapter 25E. Subchapter 25E Rights are available only with respect to shares
of a registered corporation held by a shareholder after the occurrence of a
Control Transaction; accordingly, Subchapter 25E Rights would not be available
with respect to any Shares tendered in the Offer and accepted for payment unless
Purchaser or Parent were to acquire shares representing at least 20% of the
voting power of the Company through some other means prior to the completion of
the Offer. The Merger Agreement contains a Minimum Condition (as defined in
Section 1.1 of the Merger Agreement) which generally requires that 80% of the
Shares be tendered as a condition to Purchaser's obligation to purchase the
Shares tendered in the Offer. Although under the terms of the Merger Agreement,
Parent and Purchaser may waive the
                                        7
<PAGE>   9

Minimum Condition (as defined in Section 1.1 of the Merger Agreement), they have
stated in their Schedule 14D-1 that they do not currently intend to do so.
Parent and Purchaser may terminate the Merger Agreement and the transactions
contemplated thereby (including, without limitation, the Offer) if the Minimum
Condition is not satisfied. The foregoing summary of rights under Subchapter 25E
is qualified in its entirety by reference to the full text of Subchapter 25E.

     (b) Appraisal Rights

     Notwithstanding anything in the Merger Agreement to the contrary, any
issued and outstanding Shares held by persons who object to the Merger and
comply with all the provisions of the PBCL concerning the right of holders of
Shares to dissent from the Merger and require appraisal of their Shares
("Dissenting Shareholder") will not be converted into the right to receive the
Offer Price, without interest, pursuant to the Merger Agreement, but will be
converted into the right to receive such consideration as may be determined to
be due to such Dissenting Shareholder pursuant to the PBCL; provided, however,
that the Shares outstanding immediately prior to the Effective Time and held by
a Dissenting Shareholder who will, after the Effective Time, withdraw his demand
for appraisal or lose his right of appraisal, in either case pursuant to the
PBCL, will be deemed to be converted as of the Effective Time into the right to
receive the Offer Price, payable to the holder thereof, without interest. The
Company will give Parent (i) prompt notice of any written demands for appraisals
of the Shares received by the Company and (ii) the opportunity to direct all
negotiations and proceedings with respect to any such demands. The Company will
not, without the prior written consent of Parent, voluntarily settle or
compromise any such demands.

     (c) Antitrust

     Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended
(the "HSR Act"), and the rules that have been promulgated thereunder by the
Federal Trade Commission (the "FTC"), certain acquisition transactions may not
be consummated unless certain information has been furnished to the Antitrust
Division of the United States Department of Justice (the "Antitrust Division")
and the FTC and certain waiting period requirements have been satisfied. The
acquisition of Shares by Purchaser pursuant to the Offer is subject to such
requirements. Pursuant to the requirements of the HSR Act, Parent and the
Company will file their respective required Notification and Report Forms (the
"Forms") with the Antitrust Division and the FTC as soon as practicable after
the date hereof. The statutory waiting period applicable to the purchase of
Shares pursuant to the Offer is scheduled to expire at 11:59 P.M., New York City
time, on the fifteenth day after Parent files its Form, unless early termination
of the waiting period is granted or Parent and the Company receive a request for
additional information or documentary material prior thereto. Pursuant to the
HSR Act, Parent will request early termination of the applicable waiting period.
However, prior to such date, the Antitrust Division or the FTC may extend the
waiting period by requesting additional information or documentary material
relevant to the acquisition. If such a request is made, the waiting period will
be extended until 11:59 P.M., New York City time, on the tenth day after
substantial compliance by Parent with such request. Thereafter, such waiting
periods can be extended only by court order. There can be no assurance that the
waiting period will be terminated early. The Antitrust Division and the FTC
frequently scrutinize the legality under the antitrust laws of transactions. At
any time before or after the consummation of any such transaction, the Antitrust
Division or the FTC could, notwithstanding termination of the waiting period,
take such action under the antitrust laws as either deems necessary or desirable
in the public interest, including seeking to enjoin the purchase of Shares
pursuant to the Offer or seeking divestiture of the Shares so acquired or
divestiture of substantial assets of Parent or the Company. Private parties may
also bring legal actions under the antitrust laws. There can be no assurance
that a challenge to the Offer on antitrust grounds will not be made, or if such
a challenge is made, what the results will be.

     (d) Purchaser's Designation of Persons to be Elected to the Board

     The Information Statement is attached hereto as Annex II, is filed as
Exhibit 2 to this Schedule 14D-9 and is incorporated herein by reference is
being furnished in connection with Rule 14f-1 under the Exchange Act in
connection with the possible designation by Purchaser, pursuant to the Merger
Agreement, of certain persons to be appointed to the Board other than at a
meeting of the Company's shareholders.

<PAGE>   28

of the Shares shall become entitled pursuant to Section 3.1(c). At the Effective
Time, Parent or Purchaser shall deposit, or cause to be deposited, with the
Exchange Agent for the benefit of holders of Shares the aggregate consideration
to which such holders shall be entitled at the Effective Time pursuant to
Section 3.1(c). Such funds shall be invested as directed by Parent or the
Surviving Corporation pending payment thereof by the Paying Agent to holders of
the Shares. Earnings from such investments shall be the sole and exclusive
property of Purchaser and the Surviving Corporation, and no part of such
earnings shall accrue to the benefit of holders of Shares.

                  (b) Exchange Procedures. As soon as reasonably practicable
after the Effective Time, Parent shall cause the Paying Agent to mail to each
holder of record of a Certificate or Certificates, (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
Paying Agent and shall be in such form and have such other provisions not
inconsistent with this Agreement as Parent may specify) and (ii) instructions
for use in effecting the surrender of Certificates in exchange for payment of
the Merger Consideration. Upon surrender of a Certificate for cancellation to
the Paying Agent or to such other agent or agents as may be appointed by Parent,
together with such letter of transmittal, duly executed, the holder of such
Certificate shall be entitled to receive in exchange therefor the Merger
Consideration for each Share formerly represented by such Certificate, and the
Certificate so surrendered shall forthwith be cancelled. If payment of the
Merger Consideration is to be made to a person other than the person in whose
name the surrendered Certificate is registered, it shall be a condition of
payment that the Certificate so surrendered shall be properly endorsed or shall
be otherwise in proper form for transfer and that the person requesting such
payment shall have paid any transfer and other taxes required by reason of the
payment of the Merger Consideration to a person other than the registered holder
of the Certificate surrendered or shall have established to the satisfaction of
the Surviving Corporation that such tax either has been paid or is not
applicable. Until surrendered as contemplated by this Section 3.2, each
Certificate shall be deemed at any time after the Effective Time to represent
only the right to receive the Merger Consideration in cash as contemplated by
this Section 3.2.

                  (c) Transfer Books; No Further Ownership Rights in the Shares.
At the Effective Time, the stock transfer books of the Company shall be closed,
and thereafter there shall be no further registration of transfers of the Shares
on the records of the Company. From and after the Effective Time, the holders of
Certificates evidencing ownership of the Shares outstanding immediately prior to
the Effective Time


                                     Page 23
<PAGE>   29

shall cease to have any rights with respect to such Shares, except as otherwise
provided for herein or by applicable law.

                  (d) Termination of Fund; No Liability. At any time following
six (6) months after the Effective Time, the Surviving Corporation shall be
entitled to require the Paying Agent to deliver to it any funds (including any
earnings received with respect thereto) which had been made available to the
Paying Agent and which have not been disbursed to holders of Certificates, and
thereafter such holders shall be entitled to look only to the Surviving
Corporation (subject to abandoned property, escheat or other similar laws) and
only as general creditors thereof with respect to the Merger Consideration
payable upon due surrender of their Certificates, without any interest thereon.
Notwithstanding the foregoing, neither the Surviving Corporation nor the Paying
Agent shall be liable to any holder of a Certificate for Merger Consideration
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law.

                  Section 3.3 Dissenting Shares.

                  Notwithstanding anything in this Agreement to the contrary,
Shares that are issued and outstanding immediately prior to the Effective Time
and that are held by Shareholders who (i) have not voted such shares in favor of
the Merger and (ii) have delivered timely a written demand for appraisal of such
shares in the manner provided in Chapter 15 of the PBCL shall not be cancelled
and converted into the right to receive the Merger Consideration, unless and
until such Shareholder shall have failed to perfect, or effectively shall have
withdrawn or lost, such Shareholder's right to appraisal and payment under the
PBCL, but rather, such Shareholders shall be entitled to payment of the fair
value of their shares determined and payable in accordance with the provisions
of Chapter 15, Subchapter D of the PBCL. If such Shareholder shall have so
failed to perfect, or effectively shall have withdrawn or lost such right, the
Shares owned by such Shareholder shall thereupon be deemed to have been canceled
and converted as described in Section 3.1 at the Effective Time, and each Share
owned by such Shareholder shall represent solely the right to receive the Merger
Consideration, without interest. From and after the Effective Time, no
Shareholder who has demanded appraisal rights as provided in Chapter 15,
Subchapter D of the PBCL shall be entitled to vote his or her Shares for any
purpose or to receive payment of dividends or other distributions with respect
to such shares (except payment of dividends or other distribution payable to
Shareholders of record at a date which is prior to the Effective Time). The
Company shall give Parent prompt notice of all written demands received


                                     Page 24
<PAGE>   30

by it for appraisal of Shares and shall not settle or compromise any such demand
without the prior written consent of Parent.

                  Section 3.4 Company Stock Option Plans.

                  (a) Immediately prior to the Effective Time, each holder of a
Company Option will be entitled to receive from the Company, and shall receive,
except as provided in Section 3.4(d) hereof, in settlement of each Company
Option a Parent Option. All Company Options shall terminate as of the Effective
Time. Parent shall grant, as of the Effective Time, to the holder of any Company
Option, a Parent Option. With respect to such Parent Options (i) the number of
shares of Parent Common Stock subject to such Parent Option will be determined
by multiplying the number of Shares constituting the Company Option by the
Option Exchange Ratio, rounding any fractional share up to the nearest whole
share, and (ii) the exercise price per share of such Parent Option will be
determined by dividing the exercise price per share applicable to the Company
Option by the Option Exchange Ratio, and rounding the exercise price thus
determined up to the nearest whole cent. Except as provided above, the converted
or substituted Parent Options shall be subject to the same terms and conditions
(including, without limitation, expiration date, vesting and exercise
provisions) as were applicable to the Company Option immediately prior to the
Effective Time; provided, however, that (i) all Company Options shall vest and
become fully exercisable immediately prior to the Effective Time and (ii) any
Company Option that qualifies as an incentive stock option under Code Section
422 (an "ISO") shall, to the extent permitted by applicable Legal Requirements,
be adjusted as provided in Code Section 424(a) so that the resulting Parent
Option qualifies as an ISO.

                  (b) Except as may be otherwise agreed to by Parent and the
Company, all stock option plans established by the Company or any of its
Subsidiaries shall terminate as of the Effective Time and the provisions in any
other plan, program or arrangement providing for the issuance or grant of any
other interest in respect of the capital stock of the Company or any Company
Subsidiary shall be deleted, terminated and of no further force or effect as of
the Effective Time.

                  (c) If and to the extent necessary or required by the terms of
the plans governing Company Options or pursuant to the terms of any Company
Option granted thereunder, prior to the Effective Time, the Company shall (i)
obtain the consent of each holder of outstanding Company Options and (ii) amend
the terms of the applicable Option Plan, in each case as is necessary to give
effect to the foregoing treatment of such Company Options.


                                     Page 25
<PAGE>   31

                  (d) Without limiting the foregoing, each holder of a Company
Option shall have the right (which right shall be exercised at least 5 days
prior to the Closing Date by written notice to the Company) to elect, in lieu of
the provisions of Section 3.4(a), to convert, at the Effective Time, all or a
portion of his or her Company Options which have not been exercised and which
have not expired prior to the Effective Time into the right to receive the Cash
Amount (the "Cash Election Right"). The Cash Amount shall be equal to the
product of (i) the excess, if any, of the Merger Consideration over the
exercise price per Share of such Company Option and (ii) the number of shares
constituting such Company Option, less any applicable withholding taxes.
Notwithstanding the foregoing, the Cash Election Right shall not be offered to
any holder of a Company Option that qualifies as an ISO.

regulation or order affecting the Real Property, and the continued existence,
use, occupancy and operation of each Improvement, and the right and ability to
repair such Improvement in the event of casualty, is not dependent on any
special permit, exception, approval or variance except, in each case where such
nonconforming use or dependency could not have a Material


                                     Page 32

                  (c) Except as set forth on Schedule 4.8, all properties and
assets reflected in the Financial Statements are free and clear of all

default) exists, (b) security interests incurred in connection with the purchase
of property or assets after the date of the Interim Financial Statements (such
security interests being limited to the property or assets so acquired), with
respect to which no default (or event that, with notice or lapse of time or
both, would constitute a default) exists, (c) liens for current taxes and
assessments not yet due and payable, and (d) security interests of record as
recorded in the jurisdictions set forth in Schedule 4.8. Schedule 4.8(c) sets
forth the locations of all of the properties and assets owned by the Company and
its Subsidiaries, and describes the owner of such properties and assets in each
such jurisdiction.

                  Section 4.9 Condition and Sufficiency of Assets. Except as set
forth in Schedule 4.9, the equipment of the Company and its Subsidiaries is in
good operating condition and repair and is adequate for the uses to which it is
being put, and none of such equipment is in need of maintenance or repairs
except for ordinary routine maintenance and repairs that are not in the
aggregate material in nature or cost. The equipment of the Company and its
Subsidiaries is sufficient for the continued conduct


                                     Page 33
<PAGE>   39

of the business of the Company and its Subsidiaries after the Effective Time in
substantially the same manner as conducted prior to the Effective Time.

                  Section 4.10 Accounts Receivable. Schedule 4.10 contains a
complete and accurate list of all accounts receivable that are reflected in the
Financial Statements or on the accounting records of the Company as of March 31,
1999 (the "Accounts Receivable"), which list sets forth the aging of such
Accounts Receivable. All Accounts Receivable of the Company and its Subsidiaries
as of the Effective Time represent or will represent valid obligations arising
from sales actually made or services actually performed in the ordinary course
of business. Unless paid prior to the Effective Time, the Accounts Receivable
are or will be as of the Effective Time current and collectible net of any
reserves shown in the Financial Statements or on the accounting records of the
Company as of the Effective Time (which reserves will not exceed $400,000 as of
such date), without resort to legal proceedings.

                  Section 4.11 Inventory. All inventory of the Company and its
Subsidiaries, whether or not reflected in the Financial Statements, consists of
a quality usable and salable in the ordinary course of business, except for
obsolete and slow-moving items and items of below-standard quality, all of which
have been written off or written down to net realizable value in the Financial
Statements in accordance with GAAP or on the accounting records of the Company
and its Subsidiaries as of the Effective Time, as the case may be.

                  Section 4.12 No Undisclosed Liabilities. Except as set forth
in Schedule 4.12, neither the Company nor any Company Subsidiary has any
liabilities or obligations of any nature (whether known or unknown and whether
absolute, accrued, contingent or otherwise) except for liabilities or
obligations reflected or reserved against by the Company and its Subsidiaries in
the Financial Statements and current liabilities incurred in the ordinary course
of business since the respective dates thereof which would not have a Material
Adverse Effect on the Company.

                  Section 4.13 Taxes. The Company and its Subsidiaries have
filed or caused to be filed on a timely basis all Tax Returns that are or were
required to be filed by or with respect to them, pursuant to applicable Legal
Requirements. The Company and its Subsidiaries have delivered or made available
to Parent copies of, and Schedule 4.13 contains a complete and accurate list of,
all such Tax Returns filed since January 1, 1996. The Company and its
Subsidiaries have paid, or made provision for the payment of, all Taxes that
have or may have become due pursuant to those Tax Returns or otherwise, or
pursuant to any assessment received by the Company and its


                                     Page 34
<PAGE>   40

Subsidiaries, except such Taxes, if any, as are listed in Schedule 4.13 and are
being contested in good faith and as to which adequate reserves (determined in
accordance with GAAP) have been provided in the Financial Statements. The
Company shall have no obligation for the payment of any Taxes not yet due and
payable prior to the Effective Time in excess of such Taxes accrued on its books
and records in accordance with GAAP. Neither the Company nor any Company
Subsidiary has received written notice of any claim made by an authority in a
jurisdiction where neither the Company nor any Company Subsidiary files Tax
Returns that the Company or any Company Subsidiary is or may be subject to
taxation by that jurisdiction.

                  Section 4.14 No Material Adverse Change. Since December 31,
1998 there has not been any Material Adverse Change or Material Adverse Effect.
Neither the Company nor any of its Subsidiaries has taken any of the actions
prohibited by Section 6.2 or otherwise acted in such a way as to impair, prevent
or impede the consummation of the Transactions.

                  Section 4.15 Employee Benefits.

                  (a) Schedule 4.15(a) sets forth a complete and correct list of
each "employee benefit plan", as such term is defined in section 3(3) of ERISA,
and each written bonus, incentive or deferred compensation, severance,
termination, retention, change of control, stock option or other equity-based,
performance or other employee or retiree benefit or compensation plan, program,
arrangement, agreement, policy or understanding that provides or may provide
benefits or compensation in respect of any employee or independent contractor or
under which any employee or independent contractor is or may become eligible to
participate or derive a benefit and that is or has been maintained or
established by the Company or its Subsidiaries or any other trade or business,
whether or not incorporated, which, together with the Company or its
Subsidiaries, is treated as a single employer under section 414 of the Code
(such other trades and businesses hereinafter referred to as the "Plan Related
Persons"), or to which the Company or any Plan Related Person contributes or is
or has been obligated or required to contribute or with respect to which the
Company may have any liability (collectively, the "Plans"). With respect to each
such Plan, the Company has provided Parent with complete and correct copies of,
(i) such Plan, if written, or a description of such Plan if not written, and
(ii) to the extent applicable to such Plan, all trust agreements, insurance
contracts or other funding arrangements, the two most recent actuarial and trust
reports, the two most recent Forms 5500 required to have been filed with the IRS
and all schedules thereto, the most recent IRS determination letter, all current
summary plan descriptions, any actuarial study of any post-employment life or


                                     Page 35
<PAGE>   41

medical benefits provided under any such Plan, if any, statements or other
communications regarding withdrawal or other multi-employer plan liabilities,
if any, and all amendments and modifications to any such document. Except as set
forth on Schedule 4.15(a), the Company has not communicated to any Employee or
any independent contractor any intention or commitment to modify any Plan or to
establish or implement any other employee, retiree or independent contractor
benefit or compensation plan or arrangement. Except as set forth on Schedule
4.15(a), neither the Company, nor any of its Subsidiaries, has any unwritten
Plans.

                  (b) Each Plan intended to be qualified under section 401(a) of
the Code, and the trust (if any) forming a part thereof, has received a
favorable determination letter from the IRS as to its qualification under the
Code and to the effect that each such trust is exempt from taxation under
section 501(a) of the Code, and nothing has occurred since the date of such
determination letter that could reasonably be expected to adversely affect such
qualification or tax-exempt status.

                  (c) (i) Neither the Company nor any Related Person has
         incurred (either directly or indirectly, including as a result of an
         indemnification obligation) any material liability under or pursuant to
         Title I or IV of ERISA or the penalty, excise Tax or joint and several
         liability provisions of the Code relating to employee benefit plans.
         All material contributions and premiums required to have been paid by
         the Company and each Related Person to any employee benefit plan
         (within the meaning of Section 3(3) of ERISA) (including each Plan)
         under the terms of any such plan or its related trust, insurance
         contract or other funding arrangement, or pursuant to any Legal
         Requirement have been paid within the time prescribed by any such plan,
         agreement or Legal Requirement.

                           (ii) Each of the Plans has been operated and
         administered in all material respects in compliance with its terms, all
         Legal Requirements except for any failures so to comply that,
         individually and in the aggregate, could not reasonably be expected to
         result in a material liability or obligation on the part of the Company
         or, following the Closing, Parent or any of its affiliates. There are
         no pending or, to the Knowledge of the Company, threatened claims by or
         on behalf of any of the Plans, by any employee or independent
         contractor or otherwise involving any such Plan or the assets of any
         Plan (other than routine claims for benefits).


                                     Page 36
<PAGE>   42

                           (iii) No Plan is a "multi-employer plan" within the
         meaning of section 4001(a)(3) or section 3(37) of ERISA. No Plan is a
         "multiple employer plan" within the meaning of section 4064 of ERISA.

                           (iv) With respect to each Title IV Plan, the present
         value of accrued benefits under such plan, based upon the actuarial
         assumptions used for funding purposes in the most recent actuarial
         report prepared by such plan's actuary with respect to such plan did
         not exceed, as of its latest valuation date, then current value of the
         assets of such plan allocable to such accrued benefits.

                           (v) No Title IV Plan or any trust established
         thereunder has incurred any "accumulated funding deficiency" (as
         defined in Section 302 of ERISA and Section 412 of the Code), whether
         or not waived, as of the last day of the most recent fiscal year of
         each Title IV Plan ended prior to the Closing Date. All contributions
         required to be made with respect to any Plan on or prior to the Closing
         Date have been timely made.

                  (d) Except as set forth on Schedule 4.15(d), no payment
required to be made to any employee associated with the Company or its
Subsidiaries as a result of the Merger under any contract or otherwise will, if
made, constitute an "excess parachute payment" within the meaning of Section
280G of the Code.

                  (e) Neither the Company nor any of its Subsidiaries is a party
to any Contract, agreement or other arrangement which could result in the
payment of amounts that could be nondeductible by reason of Section 162(m) of
the Code.

                  Section 4.16 Compliance with Legal Requirements; Governmental

                           (ii) no event has occurred or circumstance exists
         that (with or without notice or lapse of time) (A) may constitute or

                                     Page 37

         all or any portion of the cost of, any remedial action of any nature;
         and

                           (iii) neither the Company nor any Subsidiary has

to Knowledge to be or become untrue or inaccurate in any material respect);
provided, however, that no such notification shall affect the representations
and warranties of the parties or the conditions to the obligations of the
parties under this Agreement.

                  (b) Between the date of this Agreement and the Effective Time,
the Company will promptly notify Parent and Purchaser of the failure by the
Company to comply with or satisfy in any material respect any covenant,
condition or agreement to be complied with or satisfied by them under this
Agreement; provided, however, that no such notification shall affect the
covenants or agreements of the parties or the conditions to the obligations of
the parties under this Agreement.

                  (c) Between the date of this Agreement and the Effective Time,
the Company shall keep up to date all of the Schedules, and shall notify Parent
and Purchaser of any changes or additions or events which may, after the lapse

                  Section 6.6 No Solicitation of Competing Transaction.

                  (a) Neither the Company nor any Company Subsidiary or
Affiliate of the Company shall (and the Company shall cause the Representatives
of the Company, each Company Subsidiary and each Affiliate of the Company, not
to), directly or indirectly, encourage, solicit, participate in or initiate
discussions or negotiations with, or provide any information to, any Person or
group (other than Parent, any of its Affiliates or representatives) concerning
any Acquisition Proposal, except that nothing contained in this Section 6.6 or
any other provision hereof shall prohibit the Company or the Company Board of
Directors from (i) taking and disclosing to the Company's shareholders a
position with respect to a tender or exchange offer by a third party pursuant to

disclosure to the Company's shareholders as, in the good faith judgment of the
Company Board of Directors, after receiving advice from outside counsel, is
required


                                     Page 61
<PAGE>   67

under applicable law, provided that the Company may not, except as permitted by
Section 6.6(b), withdraw or modify, or propose to withdraw or modify, its
position with respect to the Offer or the Merger or approve or recommend, or
propose to approve or recommend any Acquisition Proposal, or enter into any
agreement with respect to any Acquisition Proposal. Upon execution of this
Agreement, the Company will immediately cease any existing activities,
discussions or negotiations with any parties conducted heretofore with respect
to any of the foregoing. Notwithstanding the foregoing, prior to the time of
acceptance of Shares for payment pursuant to the Offer, the Company may furnish
information concerning its business, properties or assets to any corporation,
partnership, person or other entity or group pursuant to appropriate
confidentiality agreements, and may negotiate and participate in discussions and
negotiations with such entity or group concerning an Acquisition Proposal if:

                           (x) such entity or group has submitted a Superior
         Proposal; and

                           (y) in the opinion of the Company Board of Directors
         such action is required to discharge the Company Board of Director's
         fiduciary duties to the Company's shareholders under applicable law,
         determined only after receipt of a written opinion from independent
         legal counsel to the Company that the failure to provide such
         information or access or to engage in such discussions or negotiations
         would cause the Company Board of Directors to violate its fiduciary
         duties to the Company's shareholders under applicable law.

The Company will immediately notify Parent of the existence of any proposal,
discussion, negotiation or inquiry received by the Company, and the Company will
immediately communicate to Parent the terms of any proposal, discussion,
negotiation or inquiry which it may receive (and will immediately provide to
Parent copies of any written materials received by the Company in connection
with such proposal, discussion, negotiation or inquiry) and the identity of the
party making such proposal or inquiry or engaging in such discussion or
negotiation. The Company will promptly provide to Parent any non-public
information concerning the Company provided to any other party which was not
previously provided to Parent. The Company will keep Parent informed of the
status and details of any such Acquisition Proposal and of any amendments or
proposed amendments to any Acquisition Proposal and will promptly (but in no
case later than 24 hours) notify Parent of any determination by the Company
Board of Directors that a Superior Proposal has been made.

                  (b) Except as set forth below in this subsection (b), neither
the Company Board of Directors nor any committee thereof shall (i) withdraw or
modify, or propose to withdraw or modify, in a manner adverse to Parent or
Purchaser, the approval or recommendation by such Board of Directors or any such
committee of the Offer, this Agreement or the Merger, (ii) approve or recommend
or propose to approve or recommend, any Acquisition Proposal or (iii) enter into
any agreement with respect to any Acquisition Proposal. Notwithstanding the
foregoing, prior to the time of acceptance for payment of Shares pursuant to the
Offer, the Company Board of Directors may withdraw or modify its approval or
recommendation of the Offer, this Agreement or the Merger, approve or recommend
a Superior Proposal, or enter into an agreement with respect to a Superior
Proposal, in each case at any time after the fifth business day following
Parent's receipt of written notice from the Company advising Parent that the
Company Board of Directors has received a Superior Proposal which it intends to
accept, specifying the material terms and conditions of such Superior Proposal,
identifying the person making such Superior Proposal, but only if the Company
shall have caused its financial and legal advisors to negotiate with Parent to
make such adjustments in the terms and conditions of this Agreement as would
enable the Company to proceed with the transactions contemplated herein on such
adjusted terms.

                  Section 6.7 Publicity. The initial press release with respect
to the execution of this Agreement shall be a joint press release acceptable to
Parent and the Company. Thereafter, so long as this Agreement is in effect,
neither the Company, Parent nor any of their respective Affiliates shall issue
or cause the publication of any press release or other announcement with respect
to the Merger, this Agreement or the other Transactions without prior
consultation with the other party, except as may be required by law or by any
listing agreement with a national securities exchange or trading market.

                  Section 6.8 Employee Arrangements

                  (a) Parent and Purchaser hereby acknowledge and agree that the
employment agreements and severance agreements set forth on Schedule 6.9(a)
constitute binding obligations of the Company and Parent and Purchaser will
honor such agreements after the Effective Time in accordance with their terms as
in effect on the date hereof.

                  (b) For a period of one (1) year following the Effective Time,
Parent and Purchaser shall continue to maintain employee benefit plans, programs
and policies for the employees of the Company which, in the aggregate, provide
benefits that are


                                     Page 63
<PAGE>   69

substantially comparable to those provided to such employees under the plans,
programs and policies maintained for such employees by the Company as of the
date hereof; provided, however, that the aggregate cost per employee of
maintaining such benefits does not increase by more than five percent (5%)
during such period.

                  Section 6.9 Officers' and Directors' Insurance;
Indemnification.

                  (a) For three (3) years after the Effective Time, Parent and
Purchaser shall maintain officers' and directors' liability insurance covering
the persons who are presently covered by the Company's officers' and directors'
liability insurance policies (copies of which have been delivered to Parent)
with respect to actions and omissions occurring prior to the Effective Time, on
terms which are not materially less favorable than the terms of such current
insurance in effect for the Company on the date hereof provided, however, that
in no event shall Parent or the Surviving Corporation be required to expend in
excess of 120% of the annual premium currently paid by the Company for such
coverage; and provided further, that, if the premium for such coverage exceeds
such amount, Parent or the Surviving Corporation shall purchase a policy with
the greatest coverage available for such 120% of the aggregate annual premiums
paid by the Company in 1999 (which the Company represents will be approximately
$47,000 on an annualized basis for 1999).

                  (b) For three (3) years after the Effective Time, Parent and
Purchaser shall maintain the rights to indemnification of officers and directors
provided for in the Company's bylaws as in effect on the date hereof, with
respect to indemnification for acts and omissions occurring prior to the
Effective Time, including without limitation, the transactions contemplated by

         8.1(b)(i) shall not be available to any party whose failure to fulfill

                           (ii) if any Governmental Body shall have issued an

                           (ii) in connection with entering into a definitive
         agreement as permitted by Section 6.6(b), provided the Company has
         complied with all provisions thereof, including the notice provisions
         therein, and that the Company makes simultaneous payment to Parent of
         funds as required by Section 9.1(b);

                           (iii) if Parent or Purchaser shall have terminated
         the Offer or the Offer expires without Parent or Purchaser, as the case
         may be, purchasing any Shares pursuant thereto; provided that the
         Company may not terminate this Agreement pursuant to this Section
         8.1(c)(ii) if the Company is in material breach of this Agreement or
         the Stock Option Agreement.

                  (d) By Parent:

                           (i) if, due to an occurrence, not involving a breach

         hereto, Parent, Purchaser, or any of their Affiliates shall have failed
         to commence the Offer on or prior to the fifth business day following

                           (ii) (A) if, prior to the purchase of Shares by

         have withdrawn, modified or changed in a manner adverse to Parent or
         Purchaser its approval or recommendation of the Offer, this Agreement
         or the Merger or shall have recommended an Acquisition Proposal or (B)
         there shall have been a material breach of Section 6.6, including but

         Purchaser or their Affiliates;

                           (iii) if prior to the purchase of Shares pursuant to
         the Offer, the Company shall have breached any representation,
         warranty, covenant or other agreement contained in this Agreement which

         promulgated under the Exchange Act) of 15% or more of the Shares or any
         such Person or group shall have announced its intention to acquire 15%
         or more of the Shares and the Company Board of Directors has failed to
         recommend against acceptance of such announcement (including by taking
         no position with respect to such announcement);

                           (v) if the Company receives an Acquisition Proposal
         from any Person (other than Parent or Purchaser), and the Company Board
         of Directors takes a neutral position or makes no recommendation with
         respect to such Acquisition Proposal after a reasonable amount of time
         (and in no event more than five business days following such receipt)
         has elapsed for the Company's Board of Directors to review and make a
         recommendation with respect to such Acquisition Proposal; or

                           (vi) if Parent or Purchaser shall have terminated the
         Offer in accordance with the terms of this Agreement without Parent or
         Purchaser purchasing any Shares thereunder; provided that Parent or
         Purchaser is not in material breach of this Agreement.

of the obligations or other acts of the other parties, (b) waive any
inaccuracies in the representations and warranties of the other parties
contained in this Agreement or in any document delivered pursuant to this
Agreement or (c) subject to the proviso of Section 9.2, waive compliance by the
other parties with any of the agreements or conditions contained in this
Agreement. Any agreement on the part of a party to any such extension or waiver
shall be valid only if set forth in an instrument in writing signed on behalf of
such party. The failure of any party to this Agreement to assert any of its
rights under this Agreement or otherwise shall not constitute a waiver of those
rights.

rights, interests or obligations hereunder shall be assigned by any of the
parties hereto (whether by operation of law or otherwise) without the prior

sole discretion, any or all of its rights, interests and obligations hereunder
to Parent or to any direct or indirect wholly owned Subsidiary of Parent.
Subject to the preceding sentence, this Agreement will be binding upon, inure

                           (h) any of the representations and warranties of the
Company set forth in this Agreement that are qualified as to materiality shall

                           (j) all consents necessary to the consummation of the
Tender Offer or the Merger including, without limitation, consents from parties
to loans, contracts, leases or other agreements and consents from governmental
agencies, whether federal, state or local shall not have been obtained, other
than consents the failure to obtain which would not have a Material Adverse

                           (l) this Agreement shall have been terminated in
accordance with its terms;

which in the reasonable good faith judgment of Parent or Purchaser, in any such
case, and regardless of the circumstances (including any action or inaction by
Parent or Purchaser) giving rise to such condition makes it inadvisable to
proceed with the Offer and/or with such acceptance for payment of or payment for
Shares.

and Purchaser, may be waived by Parent or Purchaser, in whole or in part, at any

time.

                                  TRION, INC.

                       INFORMATION STATEMENT PURSUANT TO
                    SECTION 14(F) OF THE SECURITIES EXCHANGE
                     ACT OF 1934 AND RULE 14F-1 THEREUNDER

                                  INTRODUCTION

     This Information Statement is being mailed on or about July 15, 1999 to
holders of shares of Common Stock, $0.50 par value (the "Common Stock"), of
Trion, Inc., a Pennsylvania corporation (the "Company"), in connection with the
anticipated designation of persons (the "Designated Directors") to the Board of
Directors of the Company (the "Board"). Such designation is to be made pursuant
to the Agreement and Plan of Merger (the "Merger Agreement"), dated as of July
12, 1999 by and among the Company, Fedders Corporation, a Delaware corporation
("Parent") and TI Acquisition Corp., a Pennsylvania corporation and an indirect,
wholly owned subsidiary of the Parent ("Purchaser"). On July 15, 1999, the
Purchaser commenced a tender offer (the "Offer") to purchase all outstanding
shares (the "Shares") of the Common Stock for $5.50 per share in cash (the
"Offer Price").

     NO ACTION IS REQUIRED BY THE SHAREHOLDERS OF THE COMPANY IN CONNECTION WITH
THE APPOINTMENT OF THE DESIGNATED DIRECTORS. However, Section 14(f) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and Rule 14f-1
promulgated thereunder require the mailing to the Company's shareholders of the
information set forth in this Information Statement prior to a change in a
majority of the Company's directors other than at a meeting of the Company's
shareholders.

     You are urged to read this Information Statement carefully. You are not,
however, being asked to take any action.

     The Merger Agreement provides that Parent shall be entitled to designate a
number of directors, rounded up to the next whole number, of the Board equal to
the product of the total number of directors on the Board (giving effect to the
directors designated by Parent) multiplied by a fraction of which the numerator
shall be the number of Shares which Parent and its subsidiaries (including
Purchaser) beneficially own at that time, and the denominator of which shall be
the total number of Shares then outstanding. The Directors so designated by
Parent will take office immediately after the purchase of and payment for any
Shares by Parent or any of its subsidiaries as a result of which Parent and its
subsidiaries owns beneficially at least a majority of the then outstanding
Shares. In furtherance thereof, the Company shall, upon request of Parent, use
its best efforts promptly either to increase the size of the Board or to secure
the resignation of such number of its incumbent directors, or both, as is
necessary to enable such designees of Parent to be so elected or appointed to
the Board, and the Company shall take all actions available to the Company to
cause such designees of Parent to be so elected or appointed. At such time, the
Company shall, if requested by Parent, also take all action necessary to cause
persons designated by Parent to constitute the same percentage (rounded up to
the next whole number) as is on the Board of (i) each committee of the Board,
(ii) each board of directors (or similar body) of each of the Company's
subsidiaries and (iii) each committee (or similar body) of each such board.

     The Merger Agreement provides that in the event that Parent's designees are
elected or appointed to the Board, until the Effective Time (as such term is
defined in the Merger Agreement), the Board shall have at least two directors
who were directors as of the date of the Merger Agreement and who are not
employees of the Company ("Independent Directors"), provided that, in such
event, if the number of Independent Directors shall be reduced below two for any
reason whatsoever, the remaining Independent Director shall be entitled to
designate the person to fill such vacancy who shall be deemed to be an
Independent Director or, if no Independent Director then remains, the other
directors shall designate two persons to fill such vacancies who shall not be
shareholders, affiliates or associates of Parent or Purchaser, and such persons
shall be deemed to be Independent Directors. In the event that Parent's
designees constitute a majority of the directors on the
<PAGE>   2

Board, the affirmative vote of a majority of the Independent Directors shall be
required after the acceptance for payment of Shares pursuant to the Offer and
prior to the Effective Time, to (a) amend or terminate the Merger Agreement by
the Company, (b) exercise and waive any of the Company's rights, benefits or
remedies contained in the Merger Agreement if such exercise or waiver materially
and adversely affects holders of Shares other than Parent or Purchaser, or (c)
take any other action under or in connection with the Merger Agreement if such
action materially and adversely affects holders of Shares other than Parent or
Purchaser; provided, that, if there shall be no such directors, such actions may
be effected by unanimous vote of the entire Board.

     The terms of the Merger Agreement, a summary of the events leading up to
the Offer and the execution of the Merger Agreement and certain other
information concerning the Offer and the Merger are contained in the Offer to
Purchase which is being mailed with this Information Statement, and in the
Solicitation/ Recommendation Statement on Schedule 14D-9 of the Company (the
"Schedule 14D-9") with respect to the Offer, of which this Annex I is a part.
Certain other documents (including the Merger Agreement) are filed with the
Securities and Exchange Commission (the "Commission") as exhibits to the
Schedule 14D-9 and as exhibits to the Tender Offer Statement on Schedule 14D-1
of Purchaser and Parent (the "Schedule 14D-1"). The exhibits to the Schedule
14D-9 and the Schedule 14D-1 may be examined at, and copies thereof may be
obtained from the Commission (except that the exhibits thereto cannot be
obtained from the regional offices of the Commission). In addition, the Company
is an electronic filer pursuant to the Commission's Electronic Data Gathering,
Analysis and Retrieval ("EDGAR") System. Accordingly, the aforementioned reports
and other information may be obtained by searching in the "EDGAR ARCHIVES" at
the Commission's worldwide website (http://www.sec.gov). Finally, such materials
may be inspected and copied at the offices of the National Association of
Securities Dealers, Inc., Nasdaq Reports Section, 1735 K Street, N.W.,
Washington, D.C. 20006-1506 as the Shares are listed on the Nasdaq National
Market System.

     The information contained in this Information Statement concerning Parent,
Purchaser and the Designated Directors has been furnished to the Company by
Parent. The Company assumes no responsibility for the accuracy or completeness
of such information.

            SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16 of the Exchange Act requires the Company's directors and
executive officers to file reports with the Commission indicating their holdings
of and transactions in the Company's equity securities and to provide copies of
such reports to the Company. To the Company's knowledge insiders of the Company
complied with all such filing requirements for 1998.

                   BOARD OF DIRECTORS AND EXECUTIVE OFFICERS

     The Board presently consists of eight members. Pursuant to the Company's
Bylaws, the Board may consist of no less than three and no more than fifteen
members, classified into three classes, each with, as near as possible,
one-third of the members of the Board. It is expected that the Designated
Directors will assume office promptly following the purchase of Shares by the
Purchaser. This step will be accomplished at a meeting or by written consent of
the Board providing that the size of the Board will be increased and/or
sufficient numbers of current directors will resign such that, immediately
following such action, the number of vacancies to be filled by the Designated
Directors will be available. It is currently anticipated that each of the
current directors other than Messrs. Goode and Hill will resign and that Messrs.
Goode and Hill will be the initial Independent Directors.

     The Parent and the Purchaser have informed the Company that they will
choose the Designated Directors from the persons listed below, each of whom has
consented to act as a director of the Company. If Purchaser acquires more than
50% of the Shares in the Offer, the Designated Directors will constitute a
majority of the Board after they are appointed.

                              DESIGNATED DIRECTORS

     Parent Designees.  The Parent has informed the Company that the Parent will
choose the following individuals as designees to the Board of Directors (the
"Parent Designees"): Sal Giordano, Jr., Robert L. Laurent, Jr., Michael
Giordano, Kent E. Hansen, Calvin J. Monsma and Steven L. Schneider. The names
and certain biographical information concerning the Parent Designees are set
forth below. The current business address of each Parent Designee is c/o Fedders
Corporation, 505 Martinsville Road, Liberty Corner, New Jersey 07983-0813,
except for Mr. Schneider and Mr. Monsma whose addresses are c/o Trion, Inc., 101
McNeill Road, Sanford, North Carolina 27331-0760.

     The Parent and Purchaser have informed the Company that each of the Parent
Designees listed below has consented to act as a director of the Company.

Executive Officer of Parent since 1988.

auditor, plant controller, corporate controller and Vice President, Finance.

     Michael Giordano, 35, has been Vice President and Chief Financial Officer

and a director of the Company since 1993.

     None of the Parent Designees has a familial relationship with any directors

that, to the best of Parent's knowledge, none of the Parent Designees has been
involved in any transactions with the Company or any of its directors, executive
officers or affiliates which are required to be disclosed herein pursuant to the
rules and regulations of the Commission, except as may be disclosed herein or in
the Schedule 14D-9. Four of the Parent Designees are executive officers of
Parent.

     It is expected that the Parent Designees may assume office at any time
following the purchase by the Purchaser of Shares pursuant to the Offer, which
purchase cannot be earlier than 12:00 Midnight, New York City time, on August
11, 1999, and that, upon assuming the office, the Parent Designees will

PENSION BENEFITS

     Prior to January 31, 1999, the Company maintained a noncontributory defined
benefit retirement plan (the "Plan") for all domestic employees of the Company
who completed one year of service with the Company and reached the age of 21.

     Historically, benefits under the Plan were calculated for participants on
two separate bases. With respect to any years of service prior to January 1,
1982, benefits were based on the participant's average monthly earnings during
the period from January 1, 1977 to December 31, 1981. With respect to years of
service beginning January 1, 1982, through December 31, 1995, benefits for each
participant were determined based on the individual's actual earnings, and the
annual amounts as calculated were aggregated.

                                        9
<PAGE>   10

     Beginning January 1, 1996, the Company amended the Plan to a cash balance
basis. Under the terms of the conversion to a cash balance pension plan,
benefits became based on hypothetical account balances. The benefit accrued by
each participant prior to January 1, 1996 was converted into an actuarially
equivalent cash balance amount. For 1997 and 1996, each participant accrued an
additional benefit equal to 2.75% of eligible compensation and interest was
credited on their hypothetical account balance at a rate fixed by the Board. The
rate for both 1997 and 1996 was 6.5%. Eligible compensation for purposes of the
Plan includes salary and bonus, as referenced in the Summary Compensation Table,
subject to maximum annual compensation of $150,000 which is indexed for
inflation. For 1998, the maximum annual pension payable under the Plan was
$130,000.

     The normal form of benefit payment was calculated as a straight life
annuity with joint and survivor options available. With the conversion to a cash
balance pension plan, lump sum distributions were also permitted.

     On October 24, 1997, the Board acted to freeze the Plan effective December
31, 1997 and terminate the Plan upon approval from the Internal Revenue Service.
Approval was received on November 16, 1998. Effective January 31, 1999, the plan
was terminated and all participants became fully vested and were either paid a
lump sum distribution, provided an annuity, or rolled over their accumulated
benefit balance. All Plan assets were distributed to Plan participants. Pursuant
to this distribution the named executive officers received the following amounts
on January 31, 1999: Mr. Schneider -- $51,552; Mr. Boender -- $23,377; Mr.
Monsma -- $13,784; and Mr. Haynes -- $13,290.

     Prior to the termination, the estimated annual benefit payable under the
Plan at the normal retirement age of 65 to the named executive officers was: Mr.
Schneider -- $8,631; Mr. Boender -- $5,505; Mr. Monsma -- $3,595; and Mr.
Haynes -- $2,995. Mr. Schlegel was an employee of the Company's subsidiary,
Envirco Corporation ("Envirco") which maintained only a defined contribution
pension plan.

  Agreements under the Company's 1985 Incentive Stock Option Plan

     Certain of the executive officers and key management employees of the
Company and its subsidiaries hold options granted under the Trion, Inc. 1985
Incentive Stock Option Plan (the "1985 Incentive Plan") under which options were
granted to full-time executives and other key management employees of the
Company or any subsidiary for the purchase of Common Stock. All options granted
under the 1985 Incentive Plan were evidenced by an Incentive Stock Option
Agreement between the Company and the optionee. The 1985 Incentive Plan was
approved by the Company's shareholders on April 16, 1985. The maximum number of
shares of Common Stock approved for issuance under the 1985 Incentive Plan was
161,000. Options granted under the 1985 Incentive Plan were intended to qualify
as incentive stock options. Options were granted for a term not exceeding ten
years (five years in the case of an incentive stock option granted to a person
who owned more than ten percent of the voting stock of the Company or one of its
subsidiaries) and are not transferrable other than by will or the laws of
descent and distribution. The Board terminated the 1985 Incentive Plan on April
18, 1995. The option price for the Common Stock covered by any option could not
be less than 100% of the fair market value of said Common Stock on the date the
option was granted (110% in the case of an incentive stock option granted to a
person who owns more than ten percent of the voting stock of the Company or one
of its subsidiaries). All options granted under the 1985 Incentive Plan are
fully exercisable.

  Agreements under the Company's 1995 Incentive Stock Option Plan

     Certain of the officers and other key employees of the Company and its
subsidiaries hold options or performance awards granted under the Trion, Inc.
1995 Incentive Stock Option Plan (the "1995 Incentive Plan") under which options
(either incentive stock options or non-statutory stock options), stock
appreciation rights, performance awards and other awards of Common Stock which
are valued in part by reference to the Common Stock may be granted to officers
and other key employees of the Company or any subsidiary (collectively,
"Awards"). All Awards granted under the 1995 Incentive Plan are evidenced by an
agreement between the Company and the grantee. The 1995 Incentive Plan was
approved by the Company's shareholders

                                       10
<PAGE>   11

on April 18, 1995. The maximum number of shares of Common Stock approved for
issuance under the 1995 Incentive Plan is 285,000 (subject to adjustment in
certain events). Options may be granted for a term not to exceed ten years (five
years in the case of an incentive stock option granted to a person who owns more
than ten percent of the voting stock of the Company or one of its subsidiaries)
and are not transferrable other than by will or the laws of descent and
distribution. The Board may terminate the 1995 Incentive Plan at any time prior
to its stated termination date, provided that such termination not, subject to
certain conditions, alter or impair any of the rights or obligations pursuant to
any option theretofore granted under the 1995 Incentive Plan. The option price
for the Common Stock covered by any option cannot be less than 100% of the fair
market value of said Common Stock on the date the option is granted (110% in the
case of an incentive stock option granted to a person who owns more than ten
percent of the voting stock of the Company or one of its subsidiaries). Upon a
change in control, all options outstanding become immediately and fully
exercisable.

  Stock Awards under the Non-Employee Director Stock Plan

     On January 16, 1995 the Board adopted the 1995 Non-Employee Director Stock
Plan. The shareholders of the Company approved the 1995 Non-Employee Director
Stock Plan at their 1995 annual meeting. On December 10, 1998 the Board adopted,
and the shareholders of the Company approved on April 20, 1999, an amendment to
the 1995 Non-Employee Director Stock Plan. As amended, the 1995 Non-Employee
Director Stock Plan is referred to herein as the "Director Stock Plan". The
purposes of the Director Stock Plan are to promote the interests of the Company
and its shareholders by attracting, retaining and providing an incentive to
non-employee directors by giving them an increased proprietary interest in the
Company, thereby more closely aligning their interests with those of the
shareholders of the Company. The Director Stock Plan became effective on April
18, 1995 and will remain effective until the close of business on April 18,
2000, unless the Director Stock Plan is terminated earlier by the Board. The
Director Stock Plan provides that each individual elected, reelected or
continuing as a non-employee director as of each annual meeting date shall
automatically receive an award (the "Annual Award") in an amount to be
determined by the Board. Pursuant to that authority, during 1998 and 1999 the
Board fixed the amount of the annual award to be 3,000 shares of Common Stock to
the Chairman of the Board of the Company and 1,500 shares of Common Stock for
the other non-employee directors. The aggregate number of shares of Common Stock
which may be issued under the Director Stock Plan is 45,000 shares of Common
Stock. The Board administers the Director Stock Plan and may amend or terminate
it; provided, however, that no amendment may be made without shareholder
approval if such approval is required by Rule 16b-3 under the Exchange Act
(unless the Board determines that such compliance is no longer desired) or under
any other applicable law.

COMPENSATION AGREEMENTS

  Mr. Schneider's Employment Arrangement

     On March 31, 1993 the Company and Steven L. Schneider entered into an
employment agreement which was subsequently amended and restated on July 28,
1995 and again on May 20, 1998, (as so amended and restated, the
"Schneider/Trion Agreement"), providing for his employment as President and
Chief Executive Officer for a five-year term commencing on May 24, 1993 (the
"Commencement Date"). In accordance with its terms, the Schneider/Trion
Agreement is automatically extended for additional one year periods on each
anniversary date of the Commencement Date, unless either party gives written
notice of termination at least 90 days prior to the anniversary date. The
current term of the Schneider/Trion Agreement ends on May 23, 2000. The
Schneider/Trion Agreement provides for a base salary of $214,000 per year,
subject to review and adjustment by the Board or the Compensation Committee. The
initial Schneider/Trion Agreement also provided for the grant of options to
purchase an aggregate of 175,000 shares of Common Stock described in more detail
below. In the event of Mr. Schneider's death, disability or resignation or
discharge by the Company other than a termination without cause or resignation
with good reason (as described below), the Company would pay him all accrued
obligations including his base salary through the date of termination, the
amount of any accrued bonus and incentive, deferred or other cash compensation,
and all accrued benefits under the Company's retirement, incentive and other
benefit plans. In the event of a termination without cause or resignation with
good reason, he is entitled to receive the product of three times the highest
base salary

                                       11

during the term of the Schneider/Trion Agreement plus the full target award
fixed for Mr. Schneider under the Trion, Inc. Management Incentive Plan (the
"Management Incentive Plan" and each such target award, a "target award") for
the then-current fiscal year; a pro rata incentive bonus equal to the full
target award for the then-current fiscal year; an amount equal to the sum of (A)
the maximum contributions that could have been made by the Company on Mr.
Schneider's behalf to all defined contribution plans of the Company and (B) the
present value of the benefits that Mr. Schneider could have accrued under all
defined benefit plans of the Company, had Mr. Schneider continued to participate
in such plans for a three year period following termination; and, for a period
of two years after such termination, the Company must continue to provide Mr.
Schneider insurance coverage generally provided for other Company executives or
until such time as Mr. Schneider is provided with substantially equivalent
benefits by another employer. For this purpose, a termination without cause or
resignation with good reason includes a discharge by the Company without cause
or a resignation by Mr. Schneider within one year after a substantial reduction
of Mr. Schneider's compensation or duties, a relocation of Mr. Schneider's
principal place of business to a location which is more than 50 miles from its
current location, a substantial change in the duties and responsibilities of Mr.
Schneider's current position, the giving of notice by the Company that it elects
not to extend the Schneider/Trion Agreement or a failure by the Company to cause
a successor to assume the Company's obligations under the Schneider/Trion
Agreement. The Schneider/Trion Agreement provides that the Company will
indemnify Mr. Schneider to the fullest extent permitted by law against claims
relating to his service as a director, officer or employee of the Company or any
other enterprise for which he acts in such capacity at the Company's request.

     On March 31, 1993, pursuant to the Schneider/Trion Agreement, the Company
and Mr. Schneider also entered into a Stock Option Agreement pursuant to which
the Company granted to Mr. Schneider nonstatutory stock options to purchase an
aggregate of 175,000 shares of Common Stock; consisting of options on 100,000
shares which vested on the Commencement Date at an exercise price of $2.50 per
share (the "1993 Options") and options on 75,000 shares which vested on May 24,
1994 at an exercise price of $3.00 per share (the "1994 Options"). The fair
market value of Common Stock at the time of grant of the options was $3.75 per
share. During 1995 and 1997 Mr. Schneider exercised all of the 1993 Options.

     As a condition to Parent's entering into the Merger Agreement, Parent and
Mr. Schneider entered into an employment agreement on July 12, 1999 (the
"Schneider/Parent Agreement"), providing for Mr. Schneider's employment as
Senior Vice President of Parent and Chairman and Chief Executive Officer of
Indoor Air Quality ("Indoor Air Quality"), until August 31, 2002. The
Schneider/Parent Agreement replaces and supersedes the Schneider/Trion
agreement, including the change in control provision thereof. The effectiveness
of the Schneider/Parent Agreement is conditioned upon the consummation of the
Offer. The Schneider/ Parent Agreement will be automatically extended for an
additional year as of August 31, 2002 and on each anniversary thereof unless
either party gives written notice of termination at least 180 days prior to any
such date.

     The Schneider/Parent Agreement provides for a base salary of $214,000 per
year (the "Schneider Base Salary"), subject to review and adjustment by the
Board of Directors of the Parent or the compensation committee of the Parent.
Mr. Schneider's compensation under the Schneider/Parent Agreement also includes
an annual discretionary incentive bonus equal to 50% of the Schneider Base
Salary based on the performance of the Indoor Air Quality unit and certain
individual performance targets established by the chief executive officer of
Parent. In addition, Mr. Schneider will receive as incentive compensation an
amount equal to  1/4% of the total purchase price of acquisitions of businesses
included in the Indoor Air Quality unit.

     Pursuant to the Schneider/Parent Agreement, on the date the Merger is
consummated, Mr. Schneider will be granted options to purchase 100,000 shares of
the Class A Stock of the Parent at an exercise price equal to the closing price
of Class A Stock on the New York Stock Exchange on such date. The
Schneider/Parent Agreement provides that one third of the options will vest each
year on the anniversary date of the Schneider/Parent Agreement.

     In the event of Mr. Schneider's death, disability or resignation or
discharge by Parent other than a termination without "cause" (as defined in the
Schneider/Parent Agreement), or resignation with "good

                                       12

reason" (as defined in the Schneider/Parent Agreement), Parent will pay Mr.
Schneider: (i) all accrued obligations including the Schneider Base Salary
through the date of termination, and (ii) all accrued benefits under Parent's
retirement, incentive or other benefit plans. In the event of a termination
without cause or resignation with good reason (i) Parent will pay Mr. Schneider
all accrued obligations including the Schneider Base Salary through the date of
termination; (ii) Parent will pay Mr. Schneider a lump sum equal to the balance
of the Schneider Base Salary and any incentive compensation then in effect for
the remainder of the term of the Schneider/Parent Agreement; (iii) an amount
equal to the maximum contributions that could have been made by Parent on Mr.
Schneider's behalf to all defined contribution plans of Parent on the same basis
as in effect on the date of termination of the Schneider/Parent Agreement for
the remainder of the term of the Schneider/Parent Agreement shall be paid to the
trustees of such plans; however, in the event any such plans will not allow such
payment, the Parent will pay to Mr. Schneider a lump sum in cash equal to the
total amount not accepted by such plan; (iv) Mr. Schneider shall be entitled to
receive all benefits accrued by him under the retirement, incentive or other
benefit plans in which he was participating; (v) Parent will pay all premiums
under COBRA for Mr. Schneider and his dependents if they elect coverage; and
(vi) in the event Mr. Schneider is so terminated or resigns during the initial
three year term of the Schneider/Parent Agreement, any unvested Parent stock
options granted to Mr. Schneider pursuant to the Schneider/Parent Agreement
shall vest immediately and Mr. Schneider will have 30 days to exercise such
options.

     For purposes of the Schneider/Parent Agreement, a termination without cause
or resignation with good reason includes (i) a discharge by Parent without
cause, (ii) a resignation by Mr. Schneider within one year after a substantial
reduction of Mr. Schneider's compensation, (iii) a relocation of Mr. Schneider's
principal place of business to a location which is more than 50 miles from its
current location, (iv) a substantial change in the duties and responsibilities
of Mr. Schneider's current position, or (v) any material breach of the
Schneider/Parent Agreement. The Schneider/Parent Agreement provides that Parent
will indemnify Mr. Schneider to the fullest extent permitted by law against
claims relating to his service as an officer or employee of Parent or any other
enterprise for which he acts in such capacity at Parent's request.

  Mr. Schlegel's Employment Arrangement

     On August 1, 1995 and in conjunction with the Company's acquisition of
Envirco, Mr. Schlegel, the Company and Envirco entered into an employment
agreement providing for Mr. Schlegel's employment as President and Chief
Executive of Envirco for a term continuing until August 1, 2000 (the "Schlegel
Employment Agreement"). The agreement provided for (i) an annual base salary of
$166,397 with increases at the sole discretion of the Board, based upon Mr.
Schlegel's performance and that of Envirco, (ii) participation in the Company's
Management Incentive Plan, (iii) participation in the Company's Incentive Stock
Option Plan, and (iv) participation in all other fringe benefit plans of
Envirco. In addition, the agreement provided for a Stock Option Award Agreement
by which Mr. Schlegel would be eligible for awards of options to purchase up to
20,000 shares of Common Stock, at a per share price fixed at five days prior to
the award but in no event less than $6.00 per share, in each of the five years
of the employment agreement based upon specific performance targets established
for Envirco. Under this Stock Option Award Agreement, Mr. Schlegel was awarded
20,000 shares at an exercise price of $6.00 per share for Envirco's performance
in 1995 and no awards were made for 1996, 1997 or 1998. In the event of death or
disability, Mr. Schlegel was to be paid all accrued wages, incentives and
benefits to which he is entitled under the retirement, incentive and other
benefit plans. Pursuant to the Schlegel Employment Agreement, in the event of
Mr. Schlegel's termination without cause, Mr. Schlegel was to continue to be
paid his base salary then in effect for a period of the lesser of (i) twenty
four months or (ii) the remaining employment term, with such amount being
reduced by his other gross earnings during the period such payments are payable.
Additionally, the employment agreement called for Mr. Schlegel to be paid five
annual payments of $50,000, on August 1 of each of the five years commencing
August 1, 1995 for the covenant not to compete included in the employment
agreement. The covenant includes Mr. Schlegel's agreement to protect and not
disclose confidential information.

     The Schlegel Employment Agreement was amended by the First Amendment to
Employment Agreement and Agreement Regarding Certain Other Matters dated April
21, 1999 between Mr. Schlegel, the Company and Envirco (the "Amended Schlegel
Employment Agreement"). Pursuant to the Amended

                                       13
<PAGE>   14

Schlegel Employment Agreement, Mr. Schlegel's employment as President and Chief
Executive Officer of Envirco will terminate on August 1, 1999. He is to serve as
a consultant to the Company and Envirco from August 1, 1999 to December 31,
1999. As of August 1, 1999, Mr. Schlegel's compensation and benefits will be
governed by the Amended Schlegel Employment Agreement rather than the Schlegel
Employment Agreement. The Amended Schlegel Employment Agreement provides that
Mr. Schlegel will (i) be paid $75,000 on January 5, 2000 as compensation for the
consulting services he performs under the Amended Schlegel Employment Agreement;
(ii) be paid by February 28, 2000 his prorated incentive bonus for 1999 through
July 31, 1999, (iii) as of August 1, 1999, no longer be eligible to participate

insurance plans; (v) as of August 1, 1999, no longer be eligible for any stock
option awards under the Stock Option Award Agreement; (vi) be paid for any of
his accrued and unused vacation time on August 1, 1999; and (vii) be paid
$50,000 on August 1, 1999 in consideration of Mr. Schlegel agreeing to Section 6
of the Schlegel Employment Agreement to not compete with Envirco for two years
following termination of his employment with Envirco.

  Mr. Haynes' Change in Control Agreement

     On March 29, 1999 the Company and Charles A. Haynes, Vice President of
Engineering of the Company, entered into a Change in Control Agreement (the
"Haynes Control Agreement"). The Haynes Control Agreement requires that the
Company employ Mr. Haynes for one year from the date of a Change in Control (as
defined in the recitals to the Haynes Control Agreement). During this one year
period following the date of a Change in Control, the Company must (i) pay Mr.
Haynes a base salary no less than the amount the Company paid Mr. Haynes
immediately prior to the date of a Change in Control; (ii) permit Mr. Haynes to

<PAGE>   16

benefit plans of the Company, had Mr. Haynes continued to participate in such
plans for a one year period following termination of employment; (v), to the
extent not paid, an amount equal to (A) his base salary through the date of his

any vacation, expense reimbursements and other cash entitlements accrued by Mr.
Haynes as of the date of his termination of employment; and (vi) insurance
coverage providing substantially similar benefits to those which he was
receiving immediately prior to the date of his termination of employment for a
period of one year following the date of the termination of Mr. Haynes'
employment or until such time as Mr. Haynes is provided with substantially

"termination without cause" means the occurrence within one year of the date of
a Change in Control of one of the following: a discharge by the Company of Mr.
Haynes without Cause (as defined in the Haynes Control Agreement), a substantial
reduction of Mr. Haynes' base salary, benefits or perquisites, or a relocation
of Mr. Haynes' principal place of business to a location which is more than 50
miles from its current location.

     The Haynes Control Agreement prohibits Mr. Haynes from disclosing
confidential information regarding the Company during and after his employment
with the Company.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

     The Compensation Committee of the Board makes recommendations to the Board
concerning compensation plans for the Company generally and the specific forms
and levels of compensation for executive officers of the Company. The
Compensation Committee, which is comprised of three members, each of whom is a
non-employee director, makes the following report on executive compensation:

COMPENSATION PHILOSOPHY

     The executive compensation policies established by the Board are intended
to provide compensation to the Company's executive officers at competitive
levels in order to attract and retain qualified executive officers, to reward
executive officers based on the Company's annual and long-term performance, and
to thereby enhance shareholder value. The Compensation Committee views
stock-based awards as an important means of linking compensation to corporate
performance and providing executive officers with an added incentive to enhance
shareholder value.

     The Company will not be affected for the 1998 tax year by the limitation on
deductibility of executive compensation imposed by Section 162(m) of the
Internal Revenue Code of 1986, as amended (the "Code"), and it is not presently
anticipated that Section 162(m) will affect the Company's compensation
deductions in future years. The Compensation Committee intends to review this
issue periodically.

ELEMENTS OF EXECUTIVE COMPENSATION

     Compensation of the Company's executive officers currently consists of the
following elements: base salary, cash payments under the Management Incentive
Plan as adopted for a particular year, and stock option awards, including awards
under the 1995 Incentive Plan.

     Base Salary.  As to all executive officers other than the Chief Executive
Officer, the Compensation Committee establishes base salaries primarily on the
basis of the Chief Executive Officer's recommendations. The Chief Executive
Officer's approach to determining recommended base salary for a new executive
officer includes consideration of responsibilities of the position, the
candidate's experience, skills and expertise, prior accomplishments, current
compensation, competitive salary data including various national reports and
surveys and cost of living comparisons of new location versus old location. In
order to ensure that a new officer's base salary bears a reasonable relation to
the base salaries paid to others, the compensation levels of existing executive
officers are also considered. The primary factors influencing the Chief
Executive Officer's annual recommended changes in base salaries for existing
executive officers are his personal evaluation of individual performances for
the prior year including attainment of personal objectives and goals, attainment
of

                                       16
<PAGE>   17

Company performance goals, the Company's salary structure, competitive salary
data including various national reports and surveys and the prior year's
national percentage increase in the cost of living.

     Management Incentive Plan.  Each year a Management Incentive Plan is
adopted by the Board to provide executive officers and key management employees
with cash compensation commensurate with the level of attainment of certain
performance goals. Target amounts payable under the Management Incentive Plan to
individual executives are determined at the discretion of the Board and amounts
earned, if any, are paid annually early in the succeeding year. Target amounts
are earned if certain pre-established Company and individual performance goals
are achieved. The structure and elements of each year's Management Incentive
Plan historically have been similar from year to year. Company goals under the
Management Incentive Plan for 1998 were comprised of targeted amounts of net
sales and operating income. Individual performance goals are established by the
executive officer to whom the individual reports, after consultation with the
individual. The target amounts which may be earned by individual executive
officers if performance goals are achieved are set at a specified percentage of
base salary. The target percentages for 1998 for executive officers other than
the Chief Executive Officer ranged from 35% to 50% of base salary and were set
by the Board based on the Chief Executive Officer's recommendations. The target
percentage for the Chief Executive Officer was set at 50% for 1998 by the Board.
Incentive compensation can be earned at levels below and above the targeted
percentages of base salary, with the minimum and maximum amounts for 1998 being
0% and 150% of each individual's target percentage. Threshold and maximum
Company performance criteria are established in addition to the target
performance criteria, and actual percentages of base salary earned are
determined by proration based on the level of achievement within the range
between the threshold and maximum performance criteria. No payments are made if
the threshold criteria are not met.

     Options.  The grant of stock options is intended to provide long-term
performance-based compensation to executive officers of the Company. Options
also are intended to provide executive officers with an additional incentive to
increase and promote shareholder value. The Compensation Committee approved
incentive stock option grants in 1998. Grants were based on a pool of shares
determined by the number of participants, with established minimum and maximum
numbers of shares if certain performance goals were attained. The specific
number of shares granted to individuals was provided in the recommendation. The
exercise price of the options is equal to the fair market value of the Common
Stock on the date of grant. The Board has generally granted incentive stock
options within the meaning of Section 422 of the Code, and all options granted
in 1998 were incentive stock options. The Compensation Committee also from time
to time recommends that the Board award, in its discretion, non-statutory stock
options to executive officers, particularly where a one-time grant involving a
significant number of shares is considered appropriate in connection with the
recruitment of a new executive to the Company, such as the options granted to
the Company's Chief Executive Officer in 1993 as described under the caption
"Compensation Agreements."

COMPENSATION OF CHIEF EXECUTIVE OFFICER

     Mr. Schneider's employment agreement as currently in effect and related
Stock Option Agreement are described under the caption "Compensation
Agreements."

     As is the case for each of the Company's executive officers, Mr.
Schneider's compensation currently includes three primary components: base
salary, cash payments under the Management Incentive Plan and stock option
awards. His target award under the 1998 Management Incentive Plan was 50% of
base salary, to be based 80% on Company performance and 20% on his individual
performance goals. Targeted Company performance goals established for 1998 at
the end of 1997 were weighted 40% to net sales and 60% to operating income. The
Company did not achieve the necessary corporate financial performance targets in
1998. Mr. Schneider achieved 70% of his individual performance goals. The
resulting award to Mr. Schneider was 7.0% of base salary as incentive
compensation under the 1998 Management Incentive Plan. The grant to Mr.
Schneider in February 1998 of options to purchase 11,000 shares of Common Stock
at an exercise price of

                                       17

$5.3125 per share was determined pursuant to the process described above under
"Elements of Executive Compensation -- Options".

                             STOCK OPTION AGREEMENT


         STOCK OPTION AGREEMENT, dated as of July 12, 1999 (the "Agreement"),
between Trion, Inc., a Pennsylvania corporation ("Issuer"), and Fedders
Corporation, a Delaware corporation ("Grantee").

         WHEREAS, Issuer and Grantee have entered into an Agreement and Plan of
Merger, dated as of the date hereof (the "Merger Agreement"), providing for,
among other things, upon the terms and subject to the conditions thereof, the
merger of TI Acquisition Corp., an indirect wholly owned subsidiary of the
Grantee, with and into Issuer (the "Merger"); and

         WHEREAS, as a condition and inducement to Grantee's willingness to
enter into the Merger Agreement, Grantee has requested that Issuer agree, and
Issuer has agreed, to grant Grantee the Option (as defined below).

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

         Capitalized terms used but not defined herein have the meanings set
forth in the Merger Agreement.

         1. Grant of Option. (a) Upon the terms and subject to the conditions
set forth herein, Issuer hereby grants to Grantee an unconditional, irrevocable
option (the "Option") to purchase up to 1,425,088 shares (the "Option Shares")
of Issuer's common stock, par value $0.50 per share ("Issuer Common Stock"), at
a price of $5.50 per share (the "Purchase Price"), subject to adjustment as set
forth herein.

               (b) In the event that any additional shares of Issuer Common
Stock are either (i) issued or otherwise become outstanding after the date of
this Agreement (other than pursuant to this Agreement) or (ii) redeemed,
repurchased, retired or otherwise cease to be outstanding after the date of the
Agreement, the number of Option Shares shall be increased or deceased, as
appropriate, so that, after such events, the number of Option Shares equals
19.9% of the number of shares of Issuer Common Stock then issued and
outstanding, without giving effect to any shares subject to or issued pursuant
to the Option. Nothing contained in this Section 1(b) or elsewhere in this
Agreement
<PAGE>   2
shall be deemed to authorize Issuer or Grantee to breach any provision of the
Merger Agreement.

         2. Exercise of Option. (a) Grantee may exercise the Option, with
respect to any or all of the Option Shares at any time and from time to time,
subject to the provisions of Section 2(c), after the Merger Agreement becomes
terminable under circumstances which entitle Grantee to receive the Termination
Fee under Section 9.1 of the Merger Agreement (a "Triggering Event") except that
(i) subject to the last sentence of this Section 2(a), the Option will terminate
and be of no further force and effect upon the earliest to occur of (A) the
purchase of shares of Issuer Common Stock pursuant to the Offer, (B) twelve
months after the date on which a Triggering Event occurs and (C) termination of
the Merger Agreement in accordance with its terms prior to the occurrence of a
Triggering Event, unless, in the case of clauses (B) and (C), the Grantee could
be entitled to receive the Termination Fee following such time or termination
upon the occurrence of certain events, in which case the Option will not
terminate until the later of (x) twelve months following the time such fees
become payable and (y) the expiration of the period in which the Grantee has
such right to receive the Termination Fee and (ii) any purchase of Option Shares
upon exercise of the Option will be subject to compliance with the HSR Act and
the obtaining or making of any consents, approvals, orders, notifications or
authorizations, the failure of which to have obtained or made would have the
effect of making the issuance of Option Shares illegal (the "Regulatory
Approvals") and no preliminary or permanent injunction or other order by any
court of competent jurisdiction prohibiting or otherwise restraining such
issuance shall be in effect. Notwithstanding the termination of the Option,
Grantee will be entitled to purchase the Option Shares if it has exercised the
Option in accordance with the terms hereof prior to the termination of the
Option.

         (b) In the event that Grantee wishes to exercise the Option, it will
send to Issuer a written notice (an "Exercise Notice"; the date of which being
herein referred to as the "Notice Date") to that effect specifying (i) the
number of Option Shares, if any, Grantee wishes to purchase pursuant to this
Section 2(b), (ii) the number of Option Shares, if any, with respect to which
Grantee wishes to exercise its Cash-Out Right (as defined herein) pursuant to
Section 6(c), (iii) the denominations of the certificate or certificates
evidencing the Option Shares which Grantee wishes to purchase pursuant to this
Section 2(b) and (iv) a date not earlier than three business days nor later than
60 business days from the Notice Date for the closing (an "Option Closing") of
such purchase (an "Option Closing Date"). Any Option Closing will be at an
agreed location and time in New York, New York on the applicable Option Closing
Date or at such later date as may be necessary so as to comply with clause (ii)
of Section 2(a).


                                        2
<PAGE>   3
         (c) Notwithstanding anything to the contrary contained herein, any
exercise of the Option and purchase of Option Shares shall be subject to
compliance with applicable laws and regulations, which may prohibit the purchase
of all the Option Shares specified in the Exercise Notice without first
obtaining or making certain Regulatory Approvals. In such event, if the Option
is otherwise exercisable and Grantee wishes to exercise the Option, the Option
may be exercised in accordance with Section 2(b) and Grantee shall acquire the
maximum number of Option Shares specified in the Exercise Notice that Grantee is
then permitted to acquire under the applicable laws and regulations, and if
Grantee thereafter obtains the Regulatory Approvals to acquire the remaining
balance of the Option Shares specified in the Exercise Notice, then Grantee
shall be entitled to acquire such remaining balance. Issuer agrees to use its
reasonable best efforts to assist Grantee in seeking the Regulatory Approvals.

         In the event (i) Grantee receives official notice that a Regulatory
Approval required for the purchase of any Option Shares will not be issued or
granted or (ii) such Regulatory Approval has not been issued or granted within
six months of the date of the Exercise Notice, Grantee shall have the right to
exercise its Cash-Out Right (as defined herein) pursuant to Section 6(c) with
respect to the Option Shares for which such Regulatory Approval will not be
issued or granted or has not been issued or granted.

         (d) If the aggregate amounts received by Grantee from (i) the
Termination Fee and Expenses pursuant to Section 9.1 of the Merger Agreement,
(ii) amounts from the sale or other disposition of the Option Shares, and (iii)
amounts paid pursuant to Section 6(c) hereof, exceeds the sum of (A) $2,000,000
plus (B) the aggregate amounts paid by Grantee to purchase any Option Shares
(the sum of the amounts in Section 2(d)(A) and 2(d)(B) being hereinafter
referred to as the "Maximum Profit"), then Grantee, at its sole election, shall
either (1) reduce the number of Option Shares, (2) deliver to the Issuer for
cancellation Option Shares previously purchased by Grantee (valued, for the
purposes of this Section 2(d) at the average closing sale price per share of
Issuer Common Stock (or if there is no sale on such date then the average
between the closing bid and ask prices on any such day) as reported as reported
on the Nasdaq National Market (or, if not listed on the Nasdaq National Market,
as reported on any other national securities exchange or national securities
quotation system on which the Issuer Common Stock is listed or quoted, as
reported in The Wall Street Journal (Northeast edition), or, if not reported
thereby, any other authoritative source) for the twenty consecutive trading days
preceding the day on which the amount received by Grantee pursuant to clauses
(d)(i), (ii) and (iii) above exceeds the Maximum Profit), (3) pay cash to the
Issuer or (4) any combination thereof, so that the amount received by Grantee
pursuant to clauses (d)(i), (ii) and (iii) above shall not exceed the Maximum
Profit after


                                        3
<PAGE>   4
taking into account the foregoing actions. Notwithstanding any other provision
of this Agreement, nothing in this Agreement shall affect the ability of Grantee
to receive nor relieve Issuer's obligation to pay a fee pursuant to Section 9.1
of the Merger Agreement.

         3. Payment and Delivery of Certificates. (a) At any Option Closing,
Grantee will pay to Issuer in same day funds by wire transfer to a bank account
designated in writing by Issuer an amount equal to the Purchase Price multiplied
by the number of Option Shares to be purchased at such Option Closing.

         (b) At any Option Closing, simultaneously with the delivery of same day
funds as provided in Section 3(a), Issuer will deliver to Grantee a certificate
or certificates representing the Option Shares to be purchased at such Option
Closing, which Option Shares will be free and clear of all liens, claims,
charges and encumbrances of any kind whatsoever. If at the time of issuance of
Option Shares pursuant to an exercise of the Option hereunder, Issuer shall have
issued any securities similar to rights under a shareholder rights plan, then
each Option Share issued pursuant to such exercise will also represent such a
corresponding right with terms substantially the same as and at least as
favorable to Grantee as are provided under any Issuer shareholder rights
agreement or any similar agreement then in effect.

         (c) Certificates for the Option Shares delivered at an Option Closing
will have typed or printed thereon a restrictive legend which will read
substantially as follows:

         "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY BE
         OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY IF SO REGISTERED
         OR IF AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE."

It is understood and agreed that the above legend will be removed by delivery of
substitute certificate(s) without such reference if such Option Shares have been
sold in compliance with the registration and prospectus delivery requirements of
the Securities Act, such Option Shares have been sold in reliance on and in
accordance with Rule 144 under the Securities Act or Grantee has delivered to
Issuer a copy of a letter from the staff of the SEC, or an opinion of counsel in
form and substance reasonably satisfactory to Issuer and its counsel, to the
effect that such legend is not required for purposes of the Securities Act.

         4. Representations and Warranties of Issuer. Issuer hereby represents
and warrants to Grantee as follows:

               (a) Corporate Authorization. Issuer has the corporate power and
         authority to enter into this Agreement and to carry out its obligations
         hereunder. 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 Issuer, and no other
         corporate proceedings on the part of Issuer are necessary to authorize
         this Agreement and the transactions contemplated hereby. This
         Agreement has been duly and validly executed and delivered by Issuer,
         and assuming this Agreement constitutes a valid and binding agreement
         of Grantee, this Agreement constitutes a valid and binding agreement of
         Issuer, enforceable against Issuer in accordance with its terms (except
         insofar as enforceability may be limited by applicable bankruptcy,
         insolvency, reorganization, moratorium or similar laws affecting
         creditors' rights generally, or by principles governing the
         availability of equitable remedies).

               (b) Authorized Stock. Issuer has taken all necessary corporate
         and other action to authorize and reserve and, subject to the
         expiration or termination of any required waiting period under the HSR
         Act, to permit it to issue, and, at all times from the date hereof
         until the obligation to deliver Option Shares upon the exercise of the
         Option terminates, shall have reserved for issuance, upon exercise of
         the Option, shares of Issuer Common Stock necessary for Grantee to
         exercise the Option, and Issuer will take all necessary corporate
         action to authorize and reserve (and shall at all times maintain, free
         from pre-emptive rights, sufficient authorized and reserved shares) for
         issuance all additional shares of Issuer Common Stock or other
         securities which may be issued pursuant to Section 6 upon exercise of
         the Option. The shares of Issuer Common Stock to be issued upon due
         exercise of the Option, including all additional shares of Issuer
         Common Stock or other securities which may be issuable upon exercise of
         the Option or any other securities which may be issued pursuant to
         Section 6, upon issuance pursuant hereto, will be duly and validly
         issued, fully paid and nonassessable, and will be delivered free and
         clear of all liens, claims, charges and encumbrances of any kind or
         nature whatsoever, including without limitation any preemptive rights
         of any stockholder of Issuer.

         5. Representations and Warranties of Grantee. Grantee hereby represents
and warrants to Issuer that:



                                        5
<PAGE>   6
               (a) Corporate Authorization. Grantee has the corporate power and
         authority to enter into this Agreement and to carry out its obligations
         hereunder. 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 Grantee, and no other
         corporate proceedings on the part of Grantee are necessary to authorize
         this Agreement and the transactions contemplated hereby. This Agreement
         has been duly and validly executed and delivered by Grantee, and
         assuming this Agreement constitutes a valid and binding agreement of
         Issuer, this Agreement constitutes a valid and binding agreement of
         Grantee, enforceable against Grantee in accordance with its terms
         (except insofar as enforceability may be limited by applicable
         bankruptcy, insolvency, reorganization, moratorium or similar laws
         affecting creditors' rights generally, or by principles governing the
         availability of equitable remedies).

               (b) Purchase Not For Distribution. Any Option Shares or other
         securities acquired by Grantee upon exercise of the Option will not be,
         and the Option is not being, acquired by Grantee with a view to the
         public distribution thereof. Neither the Option nor any of the Option
         Shares will be offered, sold, pledged or otherwise transferred except
         in compliance with, or pursuant to an exemption from, the registration
         requirements of the Securities Act.

         6. Adjustment upon Changes in Capitalization, Etc. (a) In the event of
any changes in Issuer Common Stock by reason of a stock dividend, stock split,
reverse stock split, merger, recapitalization, combination, exchange of shares,
or similar transaction, the type and number of shares or securities subject to
the Option, and the Purchase Price therefor, will be adjusted appropriately, and
proper provision will be made in the agreements governing such transaction, so
that Grantee will receive upon exercise of the Option the number and class of
shares or other securities or property that Grantee would have received with
respect to Issuer Common Stock if the Option had been exercised immediately
prior to such event or the record date therefor, as applicable.

         (b) Without limiting the parties' relative rights and obligations under
the Merger Agreement, in the event that the Issuer enters into an agreement (i)
to consolidate with or merge into any person, other than Grantee or one of its
subsidiaries, and Issuer will not be the continuing or surviving corporation in
such consolidation or merger, (ii) to permit any person, other than Grantee or
one of its subsidiaries, to merge into Issuer and Issuer will be the continuing
or surviving corporation, but in connection with such merger, the shares of
Issuer Common Stock outstanding immediately prior to the consummation of such
merger will be changed into or exchanged for stock or other


                                        6
<PAGE>   7
securities of Issuer or any other person or cash or any other property, or the
shares of Issuer Common Stock outstanding immediately prior to the consummation
of such merger will, after such merger represent less than 50% of the
outstanding voting securities of the merged company, or (iii) to sell or
otherwise transfer all or substantially all of its assets to any person, other
than Grantee or one of its subsidiaries, then, and in each such case, the
agreement governing such transaction will make proper provision so that the
Option will, upon the consummation of any such transaction and upon the terms
and condition set forth herein, be converted into, or exchanged for, an option
with identical terms appropriately adjusted to acquire the number and class of
shares or other securities or property that Grantee would have received in
respect of Issuer Common Stock if the Option had been exercised immediately
prior to such consolidation, merger, sale, or transfer, or the record date
therefor, as applicable and make any other necessary adjustments.

         (c) If, at any time during the period commencing on the occurrence of a
Triggering Event and ending on the termination of the Option in accordance with
Section 2, Grantee sends to Issuer an Exercise Notice indicating Grantee's
election to exercise its right (the "Cash-Out-Right") pursuant to this Section
6(c), then Issuer shall pay to Grantee, on the Option Closing Date, in exchange
for the cancellation of the Option with respect to such number of Option Shares
as Grantee specifies in the Exercise Notice, an amount in cash (the "Cash-Out
Price") equal to the amount by which (A) the highest of (i) the price per share
of Issuer Common Stock at which a tender offer or exchange offer therefor has
been made, (ii) the highest price per share of Issuer Common Stock to be paid by
any third-party pursuant to an agreement with the Issuer, (iii) the highest
closing price within the six month period immediately preceding the Notice Date
per share of Issuer Common Stock as reported on the Nasdaq National Market (or,
if not listed on the Nasdaq National Market, as reported on any other national
securities exchange or national securities quotation system on which the Issuer
Common Stock is listed or quoted, as reported in The Wall Street Journal
(Northeast edition), or, if not reported thereby, any other authoritative
source) and (iv) in the event of a sale of all or a substantial portion of
Issuer's assets, the sum of the price paid in such sale for such assets and the
current market value of the remaining assets of Issuer as determined by a
nationally recognized investment banking firm selected by the Grantee, and
reasonably acceptable to the Issuer, divided by the number of shares of Issuer
Common Stock outstanding at the time of such sale exceeds (B) the Purchase
Price, multiplied by the number of shares for which this Option is then
exercised. In determining the Cash-Out Price, the value of consideration other
than cash shall be determined by a nationally recognized investment banking firm
selected by the Grantee and reasonably acceptable to the Issuer. Grantee will
cooperate with the valuation work


                                        7
<PAGE>   8
of any investment banking firm selected pursuant to this Section 6(c).
Notwithstanding the termination of the Option, Grantee will be entitled to
exercise its rights under this Section 6(c) if it has exercised such rights in
accordance with the terms hereof prior to the termination of the Option.

         7.    Registration Rights.

               (a) At any time and from time to time within three years of the
date hereof, Grantee may by written notice (a "Registration Notice") to Issuer
request Issuer to register under the Securities Act all or part of any Issuer
Common Stock beneficially owned by Grantee (collectively, the "Registrable
Securities") in order to permit the sale or other disposition of such securities
pursuant to, at the option of Grantee, (i) a shelf registration or (ii) a bona
fide, firm commitment underwritten public offering in which Grantee shall have
the right, including with respect to any takedown off the shelf, to select the
managing underwriter, which shall be reasonably acceptable to the Issuer, and
shall effect as wide a distribution of such Registrable Securities as is
reasonably practicable and shall use reasonable efforts to prevent any person or
group from purchasing through such offering shares representing more than 3% of
the shares of Issuer Common Stock then outstanding on a fully-diluted basis.

               (b) Issuer shall use reasonable best efforts to effect, as
promptly as practicable, the registration under the Securities Act of the
Registrable Securities requested to be registered in the Registration Notice and
to keep such registration statement current; provided, however, that (i) Grantee
shall not be entitled to more than an aggregate of two effective registration
statements hereunder and (ii) Issuer will not be required to file any such
registration statement during any period of time (not to exceed 40 days after a
Registration Notice in the case of clause (A) below or 90 days after a
Registration Notice in the case of clauses (B) and (C) below) when (A) Issuer is
in possession of material non-public information which it reasonably believes
would be detrimental to be disclosed at such time and, based upon the advice of
outside securities counsel to Issuer, such information would have to be
disclosed if a registration statement were filed at that time; (B) Issuer would
be required under the Securities Act to include audited financial statements for
any period in such registration statement and such financial statements are not
yet available for inclusion in such registration statement; or (C) Issuer
determines, in its reasonable judgment, that such registration would interfere
with any financing, acquisition or other material transaction involving Issuer;
provided that the filing of such registration statement may not be delayed more
than an aggregate of 90 days after the Registration Notice. If the consummation
of the sale of any Registrable Securities pursuant to a registration hereunder
does not occur within 90 days


                                        8
<PAGE>   9
after the filing with the SEC of the initial registration statement therefor,
the provisions of this Section shall again be applicable to any proposed
registration, it being understood that Grantee shall not be entitled to more
than an aggregate of two effective registration statements hereunder. Issuer
will use reasonable best efforts to cause each such registration statement to
become effective, to obtain all consents or waivers of other parties which are
required therefor, and to keep such registration statement effective for such
period not in excess of 180 calendar days from the day such registration
statement first becomes effective as may be reasonably necessary to effect such
sale or other disposition. Issuer shall use reasonable best efforts to cause any
Registrable Securities registered pursuant to this Section to be qualified for
sale under the securities or blue sky laws of such jurisdictions as Grantee may
reasonably request and shall continue such registration or qualification in
effect in such jurisdictions; provided, however, that Issuer shall not be
required to qualify to do business in, or consent to general service of process
in, any jurisdiction.

               (c) If Issuer effects a registration under the Securities Act of
Issuer Common Stock for its own account or for any other stockholders of Issuer
(other than on Form S-4 or Form S-8, or any successor form), it will allow
Grantee the right to participate in such registration, and such participation
will not affect the obligation of Issuer to effect demand registration
statements for Grantee under this Section 7, except that, if the managing
underwriters of such offering advise Issuer in writing that in their opinion the
number of shares of Issuer Common Stock requested to be included in such
registration exceeds the number which can be sold in such offering, Issuer will
include that portion of the shares requested to be included therein equal to the
product obtained by multiplying (i) the number of shares which the underwriter
has informed the Issuer can be included in the offering and (ii) the percentage
obtained by dividing (x) the total number of shares of Issuer Common Stock held
by Grantee and (y) the total number of shares of Issuer outstanding.

               (d) The registration rights set forth in this Section are subject
to the condition that Grantee shall provide Issuer with such information with
respect to Grantee Registrable Securities, the plan for distribution thereof,
and such other information with respect to Grantee as, in the reasonable
judgment of counsel for Issuer, is necessary to enable Issuer to include in a
registration statement all material facts required to be disclosed with respect
to a registration hereunder.

               (e) A registration effected under this Section shall be effected
at Issuer's expense, except for underwriting discounts and commissions and the
fees and expenses of Grantee's counsel, and Issuer shall provide to the
underwriters such documentation


                                       9
<PAGE>   10
(including certificates, opinions of counsel and "comfort" letters from
auditors) as are customary in connection with underwritten public offerings and
as such underwriters may reasonably require. In connection with any
registration, Grantee and Issuer agree to enter into an underwriting agreement
reasonably acceptable to each such party, in form and substance customary for
transactions of this type.

               (f) In connection with a registration effected under this Section
7, Issuer shall indemnify and hold harmless Grantee, its affiliates and
controlling persons and their respective officers, directors, agents and
representatives from and against any and all losses, claims, damages,
liabilities and expenses (including, without limitation, all out-of-pocket
expenses, investigation expenses, expenses incurred with respect to any
judgement and fees and disbursements of counsel and accountants) arising out of
or based upon any statements contained in, or omissions or alleged omissions
from, each registration statement (and related prospectus) filed pursuant to
this Section 7; provided, however, that Issuer shall not be liable in any such
case to any such persons to the extent that any such loss, claim, damage,
liability (or action or proceeding in respect thereof) or expense arises out of
or is based upon an untrue statement contained in, or omission or alleged
omission from, such registration statement or prospectus in reliance upon, and
in conformity with, written information furnished to Issuer specifically for use
in the preparation thereof by Grantee.

               (g) In connection with a registration effected under this Section
7, Grantee shall indemnify and hold harmless Issuer, its affiliates and
controlling persons and their respective officers, directors, agents and
representatives from and against any and all losses, claims, damages,
liabilities and expenses (including, without limitation, all out-of-pocket
expenses, investigation expenses, expenses incurred with respect to any
judgement and fees and disbursements of counsel and accountants) arising out of
or based upon any statements contained in, or omissions or alleged omissions
from, each registration statement (and related prospectus) filed pursuant to
this Section 7 that arises out of or is based upon an untrue statement contained
in, or omission or alleged omission from, such registration statement or
prospectus in reliance upon, and in conformity with, written information
furnished to Issuer specifically for use in the preparation thereof by Grantee.

         8. Listing. If Issuer Common Stock or any other securities to be
acquired upon exercise of the Option are then listed on the Nasdaq (or any other
national securities exchange or national securities quotation system), Issuer,
upon the request of Grantee, will promptly file an application to list the
shares of Issuer Common Stock or other securities to be acquired upon exercise
of the Option on the Nasdaq (and any such other


                                       10
<PAGE>   11
national securities exchange or national securities quotation system) and will
use reasonable efforts to obtain approval of such listing as promptly as
practicable.

         9. Miscellaneous. (a) Expenses. Except as otherwise provided in the
Merger Agreement, each of the parties hereto will pay all costs and expenses
incurred by it or on its behalf in connection with the transactions contemplated
hereunder, including fees and expenses of its own financial consultants,
investment bankers, accountants and counsel.

         (b) Amendment. This Agreement may not be amended, except by an
instrument in writing signed on behalf of each of the parties.

         (c) Extension; Waiver. Any agreement on the part of a party to waive
any provision of this Agreement, or to extend the time for performance, will be
valid only if set forth in an instrument in writing signed on behalf of such
party. The failure of any party to this Agreement to assert any of its rights
under this Agreement or otherwise will not constitute a waiver of such rights.

         (d) Entire Agreement; No Third-Party Beneficiaries. This Agreement and
the Merger Agreement (i) constitute the entire agreement, and supersede all
prior agreements and understandings, both written and oral, between the parties
with respect to the subject matter of this Agreement, and (ii) are not intended
to confer upon any person other than the parties any rights or remedies in
respect of this Agreement.

         (e) Counterparts. This Agreement may be executed in two or more counter
parts, all of which shall be considered one and the same agreement and shall
become effective when two or more counterparts have been signed by each of the
parties and delivered to the other parties.

         (f) Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware without giving effect to the
principles of conflicts or choice of law thereof or of any other jurisdiction.

         (g) Notices. All notices and other communications hereunder shall be in
writing and shall be deemed given upon receipt, and shall be given to the

                              SHAREHOLDER AGREEMENT


         SHAREHOLDER AGREEMENT, dated as of July 12, 1999 (this "Agreement"),
among Fedders Corporation, a Delaware corporation (the "Parent"), TI Acquisition
Corp., a Pennsylvania corporation and an indirect wholly owned subsidiary of the
Parent ("Purchaser"), and Hugh E. Carr (the "Stockholder").

         WHEREAS, concurrently with the execution and delivery of this Agreement
the Parent, Purchaser and Trion, Inc., a Pennsylvania corporation (the
"Company"), have entered into an Agreement and Plan of Merger dated as of the
date hereof (such Agreement and Plan of Merger, as amended from time to time,
the "Merger Agreement"), which provides, among other things, that Purchaser
shall make the Offer (as defined in the Merger Agreement) to purchase at a price
of $5.50 per share, net to the sellers in cash, all of the issued and
outstanding shares of the Company's Common Stock, par value $0.50 per share (the
"Company Common Stock"), and shall merge with and into the Company (the
"Merger"), upon the terms and subject to the conditions set forth in the Merger
Agreement (any term used herein without definition shall have the definition
ascribed thereto in the Merger Agreement);

         WHEREAS, the Stockholder owns beneficially and of record shares of
Company Common Stock (such shares of Company Common Stock being collectively
referred to herein as the "Stockholder Shares"); and

         WHEREAS, as a condition to the willingness of the Parent and Purchaser
to enter into the Merger Agreement, and as an inducement to them to do so, the
Stockholder has agreed for the benefit of the Parent and Purchaser to tender the
Stockholder Shares and any other shares of Company Common Stock at any time
during the term of this Agreement held by the Stockholder, pursuant to the
Offer, to vote all the Stockholder Shares and any other shares of Company Common
Stock owned by the Stockholder in favor of the Merger, and to grant to Parent an
option to acquire all Stockholder Shares and all other shares of Company Common
Stock owned by the Stockholder under certain circumstances, all on the terms and
conditions contained in this Agreement.

         NOW, THEREFORE, in consideration of the representations, warranties,
covenants and agreements contained in this Agreement, the parties hereby agree
as follows:

                                    ARTICLE I

                             Tender Offer and Option

         SECTION 1.1. Tender of Shares. (a) Within five business days of the
commencement by Purchaser of the Offer, the Stockholder shall tender to the
Depository designated in the Offer to Purchase (the "Offer to Purchase")
distributed by Purchaser in connection with the Offer (i) a letter of
transmittal with respect to the Stockholder Shares and any other shares of
Company Common
<PAGE>   2
Stock held by the Stockholder (whether or not currently held by the Stockholder;
the Stockholder Shares, together with any shares acquired by the Stockholder in
any capacity after the date hereof and prior to the termination of this
Agreement whether upon the exercise of options, warrants or rights, the
conversion or exchange of convertible or exchangeable securities, or by means of
purchase, dividend, distribution or otherwise (the "Shares")), complying with
the terms of the Offer to Purchase, (ii) the certificates representing the
Shares, and (iii) all other documents or instruments required to be delivered
pursuant to the terms of the Offer to Purchase.

         (b) The Stockholder shall not, subject to applicable law, withdraw the
tender effected in accordance with Section 1.1(a); provided, however, that the
Stockholder may decline to tender, or may withdraw, any and all Shares owned by
the Stockholder if the Purchaser amends the Offer to (w) reduce the Offer Price
to less than $5.50 in cash, net to the stockholders, (x) reduce the number of
shares of Company Common Stock subject to the Offer, (y) change the form of
consideration payable in the Offer or (z) amend or modify any term or condition
of the Offer in a manner adverse to the stockholders of the Company (other than
insignificant changes or amendments or other than to waive any condition). The
Stockholder shall give Purchaser at least two business days' prior notice of any
withdrawal of Shares owned by the Stockholder pursuant to the immediately
preceding proviso.

         SECTION 1.2. Option. (a) The Stockholder hereby irrevocably grants
Parent an option (the "Option"), exercisable only upon the events and subject to
the conditions set forth herein, to purchase any or all of the Shares at a
purchase price per share equal to $5.50 (or such higher per share price as may
be offered by Purchaser in the Offer).

         (b) Subject to the conditions set forth in Section 1.3 and the
termination provisions of Section 6.7, Parent may exercise the Option in whole
or in part at any time prior to the date 60 days after the expiration or
termination of the Offer (such sixtieth day being herein called the "Option
Expiration Date") if (x) the Stockholder fails to comply with any of its
obligations under this Agreement or withdraws the tender of the Shares except
under the circumstances set forth in the proviso to Section 1.1(b) (but the
Option shall not limit any other right or remedy available to the Parent or
Purchaser against the Stockholder for breach of this Agreement) or (y) the Offer
is not consummated because of the failure to satisfy any of the conditions to
the Offer set forth in Annex A to the Merger Agreement (other than as a result
of any action or inaction of the Parent or Purchaser which constitutes a breach
of the Merger Agreement).

                  Upon the occurrence of any of such circumstances, Purchaser
shall be entitled to exercise the Option and (subject to Section 1.3) Parent
shall be entitled to purchase the Shares and the Stockholder shall sell the
Shares to Parent. Parent shall exercise the Option by delivering written notice
thereof to the Stockholder (the "Notice"), specifying the number of Shares to be
purchased and the date, time and place for the closing of such purchase which
date shall not be less than three business days nor more than five business days
from the date the Stockholder receives the Notice and in no event shall such
date be later than the Option Expiration Date. The closing of the purchase of
Shares pursuant to this Section 1.2 (the "Closing") shall take place on the
date, at the time and at


                                        2
<PAGE>   3
the place specified in such notice; provided, that if at such date any of the
conditions specified in Section 1.3 shall not have been satisfied (or waived),
Parent may postpone the Closing until a date within five business days after
such conditions are satisfied (but not later than the Option Expiration Date).

         (c) At the Closing, the Stockholder will deliver to Parent (in
accordance with Parent's instructions) the certificates representing the Shares
owned by the Stockholder and being purchased pursuant to Section 1.2(c), duly
endorsed or accompanied by stock powers duly executed in blank. At such Closing,
Parent shall deliver to the Stockholder, by bank wire transfer of immediately
available funds, an amount equal to the number of Shares being purchased from
the Stockholder as specified in the Notice multiplied by $5.50 (or such higher
per share price as may be offered by Parent in the Offer).

         SECTION 1.3. Conditions to Option. The obligation of Parent to purchase
the Shares at the Closing is subject to the following conditions:

                  (a) all waiting periods under the Hart-Scott-Rodino Antitrust
         Improvements Act of 1976 and the rules and regulations promulgated
         thereunder (the "HSR Act") applicable to such purchase shall have
         expired or been terminated; and

                  (b) there shall be no preliminary or permanent injunction or
         other order, decree or ruling issued by any Governmental Body, nor any
         statute, rule, regulation or order promulgated or enacted by any
         Governmental Body prohibiting, or otherwise restraining, such purchase.

         SECTION 1.4. No Purchase. Purchaser and Parent may allow the Offer to
expire without accepting for payment or paying for any Shares, on the terms and
conditions set forth in the Offer to Purchase, and may allow the Option to
expire without exercising the Option and purchasing all or any Shares pursuant
to such exercise. If all Shares validly tendered and not withdrawn are not
accepted for payment and paid for in accordance with the terms of the Offer to
Purchase or pursuant to the exercise of the Option, they shall be returned to
the Stockholder, whereupon they shall continue to be held by the Stockholder
subject to the terms and conditions of this Agreement.


                                   ARTICLE II

                               Consent and Voting

         The Stockholder hereby revokes any and all previous proxies granted
with respect to the Shares owned by the Stockholder. By entering into this
Agreement, the Stockholder hereby consents to the Merger Agreement and the
transactions contemplated thereby, including the Merger. So long as the Merger
Agreement is in effect, the Stockholder hereby agrees (i) to vote all Shares now
or hereafter owned by such Stockholder or execute a consent or proxy and not
revoke any proxy, vote


                                        3
<PAGE>   4
or consent, in favor of the Articles Amendment, the Merger Agreement, the Merger
and the transactions contemplated thereby, and (ii) to oppose any Acquisition
Proposal and to vote all Shares now or hereafter owned by such Stockholder, or
execute a consent or proxy, against any Acquisition Proposal.

                                   ARTICLE III

                    Representations, Warranties and Covenants
                               of the Stockholder

         The Stockholder represents, warrants and covenants to the Purchaser
that:

         SECTION 3.1. (a) Ownership. As of the date hereof the Stockholder is
the sole, true, lawful and beneficial owner of 197,263 Shares and that there are
no restrictions on voting rights or rights of disposition pertaining to such
Shares. The Stockholder will convey good and valid title to the Shares owned by
the Stockholder and being acquired pursuant to the Offer, the Merger or the
exercise of the Option, as the case may be, free and clear of any and all liens,
restrictions, security interests or any encumbrances whatsoever (collectively,
"Liens"). None of the Shares owned by the Stockholder is subject to any voting
trust or other agreement, arrangement or restriction with respect to the voting
of such Shares.

                  (b) Transfer of the Shares. (i) Until this Agreement is
terminated, the Stockholder shall not directly or indirectly offer to sell, sell
short, transfer (including gift), assign, pledge or otherwise dispose of or
transfer (each, a "Transfer") any interest in or encumber with any Lien any of
the Shares, (ii) enter into any contract, option, put, call, "collar" or other
agreement or understanding with respect to any Transfer of any or all of the
Shares or any interest therein; (iii) grant any proxy, power-of-attorney or
other authorization or consent in or with respect to the Shares; (iv) deposit
the Shares into a voting trust or enter into a voting agreement or arrangement
with respect to the Shares; or (v) take any other action with respect to the
Shares that would in any way restrict, limit or interfere with the performance
of its obligations hereunder.

                  (c) The Stockholder agrees to place the following legend on
any and all certificates evidencing the Shares:

         THE SHARES OF COMMON STOCK REPRESENTED BY THIS CERTIFICATE ARE SUBJECT
         TO CERTAIN RESTRICTIONS ON TRANSFER PURSUANT TO THAT SHAREHOLDER
         AGREEMENT, DATED AS OF JULY 12, 1999, BY AND AMONG PARENT, PURCHASER
         AND STOCKHOLDER. ANY TRANSFER OF SUCH SHARES OF COMMON STOCK IN
         VIOLATION OF THE TERMS OF SUCH AGREEMENT SHALL BE NULL AND VOID AND OF
         NO EFFECT WHATSOEVER.


                                        4
<PAGE>   5
         SECTION 3.2. Authority and Non-Contravention. The execution, delivery
and performance by the Stockholder of this Agreement and the consummation of the
transactions contemplated hereby (i) are within the Stockholder's power and
authority, have been duly authorized by all necessary action (including any
consultation, approval or other action by or with any other person), (ii)
require no action by or in respect of, or filing with, any Governmental Body
(except as may be required under the HSR Act and under the Securities Exchange
Act of 1934, as amended, and the rules and regulations promulgated thereunder
(the "Exchange Act")), and (iii) do not and will not contravene or constitute a
default under, or give rise to a right of termination, cancellation or
acceleration of any right or obligation of the Stockholder or to a loss of any
benefit of the Stockholder under, any provision of applicable law or regulation
or any agreement, judgment, injunction, order, decree, or other instrument
binding on the Stockholder or result in the imposition of any Lien on any assets

         or Purchaser, as the case may be, would have received in respect of the
         Shares purchasable pursuant to the Offer or the exercise of the Option

         SECTION 6.11. Stockholder Capacity. The Stockholder signs solely in its
capacity as the record holder and beneficial owner of the Shares and nothing
herein shall limit or affect any actions taken by the Stockholder in his or her
capacity as an officer, director, partner, employee or affiliate of the Company

         SECTION 6.12. Severability. If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of law,
or public policy, all other


                                       8
<PAGE>   9
conditions and provisions of this Agreement shall nevertheless remain in full
force and effect so long as the economic or legal substance of the transactions
contemplated hereby are not affected in any manner materially adverse to any
party. Upon such determination that any term or other provision is invalid,
illegal or incapable of being enforced, the parties shall negotiate in good
faith to modify this Agreement so as to effect the original intent of the
parties as closely as possible in a mutually acceptable manner in order that the
transactions be consummated as originally contemplated to the fullest extent
possible. To the extent that any provision of this Agreement and the Merger

         SHAREHOLDER AGREEMENT, dated as of July 12, 1999 (this "Agreement"),
among Fedders Corporation, a Delaware corporation (the "Parent"), TI Acquisition
Corp., a Pennsylvania corporation and an indirect wholly owned subsidiary of the
Parent ("Purchaser"), and Joseph W.
Deering (the "Stockholder").

         WHEREAS, concurrently with the execution and delivery of this Agreement
the Parent, Purchaser and Trion, Inc., a Pennsylvania corporation (the
"Company"), have entered into an Agreement and Plan of Merger dated as of the
date hereof (such Agreement and Plan of Merger, as amended from time to time,
the "Merger Agreement"), which provides, among other things, that Purchaser
shall make the Offer (as defined in the Merger Agreement) to purchase at a price

"Company Common Stock"), and shall merge with and into the Company (the
"Merger"), upon the terms and subject to the conditions set forth in the Merger
Agreement (any term used herein without definition shall have the definition
ascribed thereto in the Merger Agreement);

         WHEREAS, the Stockholder owns beneficially and of record shares of
Company Common Stock (such shares of Company Common Stock being collectively
referred to herein as the "Stockholder Shares"); and

         WHEREAS, as a condition to the willingness of the Parent and Purchaser
to enter into the Merger Agreement, and as an inducement to them to do so, the
Stockholder has agreed for the benefit of the Parent and Purchaser to tender the
Stockholder Shares and any other shares of Company Common Stock at any time
during the term of this Agreement held by the Stockholder, pursuant to the
Offer, to vote all the Stockholder Shares and any other shares of Company Common
Stock owned by the Stockholder in favor of the Merger, and to grant to Parent an
option to acquire all Stockholder Shares and all other shares of Company Common
Stock owned by the Stockholder under certain circumstances, all on the terms and
conditions contained in this Agreement.

         NOW, THEREFORE, in consideration of the representations, warranties,
covenants and agreements contained in this Agreement, the parties hereby agree
as follows:
<PAGE>   12
                                    ARTICLE I

                             Tender Offer and Option

         SECTION 1.1. Tender of Shares. (a) Within five business days of the
commencement by Purchaser of the Offer, the Stockholder shall tender to the
Depository designated in the Offer to Purchase (the "Offer to Purchase")
distributed by Purchaser in connection with the Offer (i) a letter of
transmittal with respect to the Stockholder Shares and any other shares of
Company Common Stock held by the Stockholder (whether or not currently held by
the Stockholder; the Stockholder Shares, together with any shares acquired by
the Stockholder in any capacity after the date hereof and prior to the
termination of this Agreement whether upon the exercise of options, warrants or
rights, the conversion or exchange of convertible or exchangeable securities, or
by means of purchase, dividend, distribution or otherwise (the "Shares")),
complying with the terms of the Offer to Purchase, (ii) the certificates
representing the Shares, and (iii) all other documents or instruments required
to be delivered pursuant to the terms of the Offer to Purchase.

         (b) The Stockholder shall not, subject to applicable law, withdraw the
tender effected in accordance with Section 1.1(a); provided, however, that the
Stockholder may decline to tender, or may withdraw, any and all Shares owned by
the Stockholder if the Purchaser amends the Offer to (w) reduce the Offer Price
to less than $5.50 in cash, net to the stockholders, (x) reduce the number of
shares of Company Common Stock subject to the Offer, (y) change the form of
consideration payable in the Offer or (z) amend or modify any term or condition
of the Offer in a manner adverse to the stockholders of the Company (other than
insignificant changes or amendments or other than to waive any condition). The
Stockholder shall give Purchaser at least two business days' prior notice of any
withdrawal of Shares owned by the Stockholder pursuant to the immediately
preceding proviso.

         SECTION 1.2. Option. (a) The Stockholder hereby irrevocably grants
Parent an option (the "Option"), exercisable only upon the events and subject to
the conditions set forth herein, to purchase any or all of the Shares at a
purchase price per share equal to $5.50 (or such higher per share price as may
be offered by Purchaser in the Offer).

         (b) Subject to the conditions set forth in Section 1.3 and the
termination provisions of Section 6.7, Parent may exercise the Option in whole
or in part at any time prior to the date 60 days after the expiration or
termination of the Offer (such sixtieth day being herein called the "Option
Expiration Date") if (x) the Stockholder fails to comply with any of its
obligations under this Agreement or withdraws the tender of the Shares except
under the circumstances set forth in the proviso to Section 1.1(b) (but the
Option shall not limit any other right or remedy available to the Parent or
Purchaser against the Stockholder for breach of this Agreement) or (y) the Offer
is not consummated because of the failure to satisfy any of the conditions to
the Offer set forth in Annex A to the Merger Agreement (other than as a result
of any action or inaction of the Parent or Purchaser which constitutes a breach
of the Merger Agreement).


                                        2
<PAGE>   13
                  Upon the occurrence of any of such circumstances, Purchaser
shall be entitled to exercise the Option and (subject to Section 1.3) Parent
shall be entitled to purchase the Shares and the Stockholder shall sell the
Shares to Parent. Parent shall exercise the Option by delivering written notice
thereof to the Stockholder (the "Notice"), specifying the number of Shares to be
purchased and the date, time and place for the closing of such purchase which
date shall not be less than three business days nor more than five business days
from the date the Stockholder receives the Notice and in no event shall such
date be later than the Option Expiration Date. The closing of the purchase of
Shares pursuant to this Section 1.2 (the "Closing") shall take place on the
date, at the time and at the place specified in such notice; provided, that if
at such date any of the conditions specified in Section 1.3 shall not have been
satisfied (or waived), Parent may postpone the Closing until a date within five
business days after such conditions are satisfied (but not later than the Option
Expiration Date).

         (c) At the Closing, the Stockholder will deliver to Parent (in
accordance with Parent's instructions) the certificates representing the Shares
owned by the Stockholder and being purchased pursuant to Section 1.2(c), duly
endorsed or accompanied by stock powers duly executed in blank. At such Closing,
Parent shall deliver to the Stockholder, by bank wire transfer of immediately
available funds, an amount equal to the number of Shares being purchased from
the Stockholder as specified in the Notice multiplied by $5.50 (or such higher
per share price as may be offered by Parent in the Offer).

         SECTION 1.3. Conditions to Option. The obligation of Parent to purchase
the Shares at the Closing is subject to the following conditions:

                  (a) all waiting periods under the Hart-Scott-Rodino Antitrust
         Improvements Act of 1976 and the rules and regulations promulgated
         thereunder (the "HSR Act") applicable to such purchase shall have
         expired or been terminated; and

                  (b) there shall be no preliminary or permanent injunction or
         other order, decree or ruling issued by any Governmental Body, nor any
         statute, rule, regulation or order promulgated or enacted by any
         Governmental Body prohibiting, or otherwise restraining, such purchase.

         SECTION 1.4. No Purchase. Purchaser and Parent may allow the Offer to
expire without accepting for payment or paying for any Shares, on the terms and
conditions set forth in the Offer to Purchase, and may allow the Option to
expire without exercising the Option and purchasing all or any Shares pursuant
to such exercise. If all Shares validly tendered and not withdrawn are not
accepted for payment and paid for in accordance with the terms of the Offer to
Purchase or pursuant to the exercise of the Option, they shall be returned to
the Stockholder, whereupon they shall continue to be held by the Stockholder
subject to the terms and conditions of this Agreement.

         The Stockholder hereby revokes any and all previous proxies granted
with respect to the Shares owned by the Stockholder. By entering into this
Agreement, the Stockholder hereby consents to the Merger Agreement and the

short, transfer (including gift), assign, pledge or otherwise dispose of or
transfer (each, a "Transfer") any interest in or encumber with any Lien any of
the Shares, (ii) enter into any contract, option, put, call, "collar" or other
agreement or understanding with respect to any Transfer of any or all of the
Shares or any interest therein; (iii) grant any proxy, power-of-attorney or
other authorization or consent in or with respect to the Shares; (iv) deposit
the Shares into a voting trust or enter into a voting agreement or arrangement
with respect to the Shares; or (v) take any other action with respect to the

covenants and agrees that:

                  (a) No Solicitation. The Stockholder shall not directly or

         recapitalization, combinations, conversions, exchanges of shares,
         extraordinary or liquidating dividends, or other changes in the
         corporate or capital structure of the Company which would have the

         the number and kind of shares or securities subject to this Agreement
         and the price set forth herein at which Shares may be purchased from
         the Stockholder pursuant to the Offer or the exercise of the Option
         shall be appropriately and equitably adjusted so that Parent and
         Purchaser shall receive pursuant to the Offer or the exercise of the
         Option the number and class of shares or other securities or property
         that Parent or Purchaser, as the case may be, would have received in
         respect of the Shares purchasable pursuant to the Offer or the exercise
         of the Option if such purchase had occurred immediately prior to such
         event.


                                   ARTICLE VI

to consummate and make effective the transactions contemplated by this
Agreement.

         SECTION 6.4. Specific Performance. The parties acknowledge and agree

Stockholder for any breach by the other party or parties of any agreement,
covenant or representation hereunder.

         SECTION 6.5. Notices. All notices, requests, claims, demands and other
communications hereunder shall be deemed to have been duly given when delivered

         SECTION 6.7. Amendments; Termination. This Agreement may not be
modified, amended, altered or supplemented, except upon the execution and
delivery of a written agreement executed by the parties hereto. Notwithstanding
anything herein to the contrary, this Agreement shall expire and be of no
further force or effect if (i) the conditions to the Purchaser's obligations to
accept for payment and pay for Shares pursuant to the Offer shall have been
satisfied and the Purchaser breaches any obligation of Purchaser under the
Merger Agreement to accept for payment and promptly pay for all Shares validly
tendered and not withdrawn pursuant to the Offer upon expiration of the Offer or

provided further that except as set forth in the prior clause, a party may not
assign, delegate or otherwise transfer any of its rights or obligations under
this Agreement without the consent of the other parties hereto and any purported
assignment, delegation or transfer without such consent shall be null and void.

         SECTION 6.9. Governing Law. This Agreement shall be construed in
accordance with and governed by the law of Delaware without giving effect to the
principles of conflicts of laws thereof.

         SECTION 6.10. Counterparts; Effectiveness. This Agreement may be signed

effects as if the signatures


                                        8
<PAGE>   19
thereto and thereof were upon the same instrument. This Agreement shall become
effective when each party hereto shall have received counterparts hereof signed
by all of the other parties hereto.

         SECTION 6.11. Stockholder Capacity. The Stockholder signs solely in its
capacity as the record holder and beneficial owner of the Shares and nothing
herein shall limit or affect any actions taken by the Stockholder in his or her
capacity as an officer, director, partner, employee or affiliate of the Company
and no such actions shall be deemed a breach of this Agreement.

         SECTION 6.12. Severability. If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of law,
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions contemplated hereby are not affected in any manner
materially adverse to any party. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the parties as closely as possible in a mutually acceptable manner in
order that the transactions be consummated as originally contemplated to the
fullest extent possible. To the extent that any provision of this Agreement and
the Merger Agreement conflict, the provisions of the Merger Agreement shall
control.

                              SHAREHOLDER AGREEMENT


         SHAREHOLDER AGREEMENT, dated as of July 12, 1999 (this "Agreement"),
among Fedders Corporation, a Delaware corporation (the "Parent"), TI Acquisition
Corp., a Pennsylvania corporation and an indirect wholly owned subsidiary of the
Parent ("Purchaser"), and Seddon Goode, Jr. (the "Stockholder").

         WHEREAS, concurrently with the execution and delivery of this Agreement
the Parent, Purchaser and Trion, Inc., a Pennsylvania corporation (the
"Company"), have entered into an Agreement and Plan of Merger dated as of the
date hereof (such Agreement and Plan of Merger, as amended from time to time,
the "Merger Agreement"), which provides, among other things, that Purchaser
shall make the Offer (as defined in the Merger Agreement) to purchase at a price
of $5.50 per share, net to the sellers in cash, all of the issued and
outstanding shares of the Company's Common Stock, par value $0.50 per share (the
"Company Common Stock"), and shall merge with and into the Company (the
"Merger"), upon the terms and subject to the conditions set forth in the Merger
Agreement (any term used herein without definition shall have the definition
ascribed thereto in the Merger Agreement);

         WHEREAS, the Stockholder owns beneficially and of record shares of
Company Common Stock (such shares of Company Common Stock being collectively
referred to herein as the "Stockholder Shares"); and

         WHEREAS, as a condition to the willingness of the Parent and Purchaser
to enter into the Merger Agreement, and as an inducement to them to do so, the
Stockholder has agreed for the benefit of the Parent and Purchaser to tender the
Stockholder Shares and any other shares of Company Common Stock at any time
during the term of this Agreement held by the Stockholder, pursuant to the
Offer, to vote all the Stockholder Shares and any other shares of Company Common
Stock owned by the Stockholder in favor of the Merger, and to grant to Parent an
option to acquire all Stockholder Shares and all other shares of Company Common
Stock owned by the Stockholder under certain circumstances, all on the terms and
conditions contained in this Agreement.

         NOW, THEREFORE, in consideration of the representations, warranties,
covenants and agreements contained in this Agreement, the parties hereby agree
as follows:
<PAGE>   22
                                    ARTICLE I

                             Tender Offer and Option

         SECTION 1.1. Tender of Shares. (a) Within five business days of the
commencement by Purchaser of the Offer, the Stockholder shall tender to the
Depository designated in the Offer to Purchase (the "Offer to Purchase")
distributed by Purchaser in connection with the Offer (i) a letter of
transmittal with respect to the Stockholder Shares and any other shares of
Company Common Stock held by the Stockholder (whether or not currently held by
the Stockholder; the Stockholder Shares, together with any shares acquired by
the Stockholder in any capacity after the date hereof and prior to the
termination of this Agreement whether upon the exercise of options, warrants or
rights, the conversion or exchange of convertible or exchangeable securities, or
by means of purchase, dividend, distribution or otherwise (the "Shares")),
complying with the terms of the Offer to Purchase, (ii) the certificates
representing the Shares, and (iii) all other documents or instruments required
to be delivered pursuant to the terms of the Offer to Purchase.

         (b) The Stockholder shall not, subject to applicable law, withdraw the
tender effected in accordance with Section 1.1(a); provided, however, that the
Stockholder may decline to tender, or may withdraw, any and all Shares owned by
the Stockholder if the Purchaser amends the Offer to (w) reduce the Offer Price
to less than $5.50 in cash, net to the stockholders, (x) reduce the number of
shares of Company Common Stock subject to the Offer, (y) change the form of
consideration payable in the Offer or (z) amend or modify any term or condition
of the Offer in a manner adverse to the stockholders of the Company (other than
insignificant changes or amendments or other than to waive any condition). The
Stockholder shall give Purchaser at least two business days' prior notice of any
withdrawal of Shares owned by the Stockholder pursuant to the immediately
preceding proviso.

         SECTION 1.2. Option. (a) The Stockholder hereby irrevocably grants
Parent an option (the "Option"), exercisable only upon the events and subject to
the conditions set forth herein, to purchase any or all of the Shares at a
purchase price per share equal to $5.50 (or such higher per share price as may
be offered by Purchaser in the Offer).

         (b) Subject to the conditions set forth in Section 1.3 and the
termination provisions of Section 6.7, Parent may exercise the Option in whole
or in part at any time prior to the date 60 days after the expiration or
termination of the Offer (such sixtieth day being herein called the "Option
Expiration Date") if (x) the Stockholder fails to comply with any of its
obligations under this Agreement or withdraws the tender of the Shares except
under the circumstances set forth in the proviso to Section 1.1(b) (but the
Option shall not limit any other right or remedy available to the Parent or
Purchaser against the Stockholder for breach of this Agreement) or (y) the Offer
is not consummated because of the failure to satisfy any of the conditions to
the Offer set forth in Annex A to the Merger Agreement (other than as a result
of any action or inaction of the Parent or Purchaser which constitutes a breach
of the Merger Agreement).


                                        2
<PAGE>   23
                  Upon the occurrence of any of such circumstances, Purchaser
shall be entitled to exercise the Option and (subject to Section 1.3) Parent
shall be entitled to purchase the Shares and the Stockholder shall sell the
Shares to Parent. Parent shall exercise the Option by delivering written notice
thereof to the Stockholder (the "Notice"), specifying the number of Shares to be
purchased and the date, time and place for the closing of such purchase which
date shall not be less than three business days nor more than five business days
from the date the Stockholder receives the Notice and in no event shall such
date be later than the Option Expiration Date. The closing of the purchase of
Shares pursuant to this Section 1.2 (the "Closing") shall take place on the
date, at the time and at the place specified in such notice; provided, that if
at such date any of the conditions specified in Section 1.3 shall not have been
satisfied (or waived), Parent may postpone the Closing until a date within five
business days after such conditions are satisfied (but not later than the Option
Expiration Date).

         (c) At the Closing, the Stockholder will deliver to Parent (in
accordance with Parent's instructions) the certificates representing the Shares
owned by the Stockholder and being purchased pursuant to Section 1.2(c), duly
endorsed or accompanied by stock powers duly executed in blank. At such Closing,
Parent shall deliver to the Stockholder, by bank wire transfer of immediately
available funds, an amount equal to the number of Shares being purchased from
the Stockholder as specified in the Notice multiplied by $5.50 (or such higher
per share price as may be offered by Parent in the Offer).

         SECTION 1.3. Conditions to Option. The obligation of Parent to purchase
the Shares at the Closing is subject to the following conditions:

                  (a) all waiting periods under the Hart-Scott-Rodino Antitrust
         Improvements Act of 1976 and the rules and regulations promulgated
         thereunder (the "HSR Act") applicable to such purchase shall have
         expired or been terminated; and

                  (b) there shall be no preliminary or permanent injunction or
         other order, decree or ruling issued by any Governmental Body, nor any
         statute, rule, regulation or order promulgated or enacted by any
         Governmental Body prohibiting, or otherwise restraining, such purchase.

         SECTION 1.4. No Purchase. Purchaser and Parent may allow the Offer to
expire without accepting for payment or paying for any Shares, on the terms and
conditions set forth in the Offer to Purchase, and may allow the Option to
expire without exercising the Option and purchasing all or any Shares pursuant
to such exercise. If all Shares validly tendered and not withdrawn are not
accepted for payment and paid for in accordance with the terms of the Offer to
Purchase or pursuant to the exercise of the Option, they shall be returned to
the Stockholder, whereupon they shall continue to be held by the Stockholder
subject to the terms and conditions of this Agreement.

                               Consent and Voting

         The Stockholder hereby revokes any and all previous proxies granted
with respect to the Shares owned by the Stockholder. By entering into this
Agreement, the Stockholder hereby consents to the Merger Agreement and the
transactions contemplated thereby, including the Merger. So long as the Merger
Agreement is in effect, the Stockholder hereby agrees (i) to vote all Shares now
or hereafter owned by such Stockholder or execute a consent or proxy and not
revoke any proxy, vote or consent, in favor of the Articles Amendment, the
Merger Agreement, the Merger and the transactions contemplated thereby, and (ii)
to oppose any Acquisition Proposal and to vote all Shares now or hereafter owned
by such Stockholder, or execute a consent or proxy, against any Acquisition
Proposal.

                    Representations, Warranties and Covenants
                               of the Stockholder

         The Stockholder represents, warrants and covenants to the Purchaser
that:

         SECTION 3.1. (a) Ownership. As of the date hereof the Stockholder is
the sole, true, lawful and beneficial owner of 82,858 Shares and that there are
no restrictions on voting rights or rights of disposition pertaining to such
Shares. The Stockholder will convey good and valid title to the Shares owned by
the Stockholder and being acquired pursuant to the Offer, the Merger or the
exercise of the Option, as the case may be, free and clear of any and all liens,
restrictions, security interests or any encumbrances whatsoever (collectively,
"Liens"). None of the Shares owned by the Stockholder is subject to any voting
trust or other agreement, arrangement or restriction with respect to the voting
of such Shares.

         extraordinary or liquidating dividends, or other changes in the

         the number and kind of shares or securities subject to this Agreement
         and the price set forth herein at which Shares may be purchased from
         the Stockholder pursuant to the Offer or the exercise of the Option

         Option the number and class of shares or other securities or property
         that Parent or Purchaser, as the case may be, would have received in
         respect of the Shares purchasable pursuant to the Offer or the exercise
         of the Option if such purchase had occurred immediately prior to such
         event.

         SECTION 6.7. Amendments; Termination. This Agreement may not be
modified, amended, altered or supplemented, except upon the execution and
delivery of a written agreement executed by the parties hereto. Notwithstanding
anything herein to the contrary, this Agreement shall expire and be of no
further force or effect if (i) the conditions to the Purchaser's obligations to
accept for payment and pay for Shares pursuant to the Offer shall have been
satisfied and the Purchaser breaches any obligation of Purchaser under the
Merger Agreement to accept for payment and promptly pay for all Shares validly
tendered and not withdrawn pursuant to the Offer upon expiration of the Offer or

provided further that except as set forth in the prior clause, a party may not

principles of conflicts of laws thereof.

         SECTION 6.10. Counterparts; Effectiveness. This Agreement may be signed

effects as if the signatures


                                        8
<PAGE>   29
thereto and thereof were upon the same instrument. This Agreement shall become
effective when each party hereto shall have received counterparts hereof signed
by all of the other parties hereto.

         SECTION 6.11. Stockholder Capacity. The Stockholder signs solely in its
capacity as the record holder and beneficial owner of the Shares and nothing
herein shall limit or affect any actions taken by the Stockholder in his or her
capacity as an officer, director, partner, employee or affiliate of the Company
and no such actions shall be deemed a breach of this Agreement.

         SECTION 6.12. Severability. If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of law,
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions contemplated hereby are not affected in any manner
materially adverse to any party. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the parties as closely as possible in a mutually acceptable manner in
order that the transactions be consummated as originally contemplated to the
fullest extent possible. To the extent that any provision of this Agreement and
the Merger Agreement conflict, the provisions of the Merger Agreement shall
control.

                              SHAREHOLDER AGREEMENT


         SHAREHOLDER AGREEMENT, dated as of July 12, 1999 (this "Agreement"),
among Fedders Corporation, a Delaware corporation (the "Parent"), TI Acquisition
Corp., a Pennsylvania corporation and an indirect wholly owned subsidiary of the
Parent ("Purchaser"), and James E.
Heins (the "Stockholder").

         WHEREAS, concurrently with the execution and delivery of this Agreement
the Parent, Purchaser and Trion, Inc., a Pennsylvania corporation (the
"Company"), have entered into an Agreement and Plan of Merger dated as of the
date hereof (such Agreement and Plan of Merger, as amended from time to time,
the "Merger Agreement"), which provides, among other things, that Purchaser
shall make the Offer (as defined in the Merger Agreement) to purchase at a price
of $5.50 per share, net to the sellers in cash, all of the issued and
outstanding shares of the Company's Common Stock, par value $0.50 per share (the
"Company Common Stock"), and shall merge with and into the Company (the
"Merger"), upon the terms and subject to the conditions set forth in the Merger
Agreement (any term used herein without definition shall have the definition
ascribed thereto in the Merger Agreement);

         WHEREAS, the Stockholder owns beneficially and of record shares of
Company Common Stock (such shares of Company Common Stock being collectively
referred to herein as the "Stockholder Shares"); and

         WHEREAS, as a condition to the willingness of the Parent and Purchaser
to enter into the Merger Agreement, and as an inducement to them to do so, the
Stockholder has agreed for the benefit of the Parent and Purchaser to tender the
Stockholder Shares and any other shares of Company Common Stock at any time
during the term of this Agreement held by the Stockholder, pursuant to the
Offer, to vote all the Stockholder Shares and any other shares of Company Common
Stock owned by the Stockholder in favor of the Merger, and to grant to Parent an
option to acquire all Stockholder Shares and all other shares of Company Common
Stock owned by the Stockholder under certain circumstances, all on the terms and
conditions contained in this Agreement.

         NOW, THEREFORE, in consideration of the representations, warranties,
covenants and agreements contained in this Agreement, the parties hereby agree
as follows:
<PAGE>   32
                                    ARTICLE I

                             Tender Offer and Option

         SECTION 1.1. Tender of Shares. (a) Within five business days of the
commencement by Purchaser of the Offer, the Stockholder shall tender to the
Depository designated in the Offer to Purchase (the "Offer to Purchase")
distributed by Purchaser in connection with the Offer (i) a letter of
transmittal with respect to the Stockholder Shares and any other shares of
Company Common Stock held by the Stockholder (whether or not currently held by
the Stockholder; the Stockholder Shares, together with any shares acquired by
the Stockholder in any capacity after the date hereof and prior to the
termination of this Agreement whether upon the exercise of options, warrants or
rights, the conversion or exchange of convertible or exchangeable securities, or
by means of purchase, dividend, distribution or otherwise (the "Shares")),
complying with the terms of the Offer to Purchase, (ii) the certificates
representing the Shares, and (iii) all other documents or instruments required
to be delivered pursuant to the terms of the Offer to Purchase.

         (b) The Stockholder shall not, subject to applicable law, withdraw the
tender effected in accordance with Section 1.1(a); provided, however, that the
Stockholder may decline to tender, or may withdraw, any and all Shares owned by
the Stockholder if the Purchaser amends the Offer to (w) reduce the Offer Price
to less than $5.50 in cash, net to the stockholders, (x) reduce the number of
shares of Company Common Stock subject to the Offer, (y) change the form of
consideration payable in the Offer or (z) amend or modify any term or condition
of the Offer in a manner adverse to the stockholders of the Company (other than
insignificant changes or amendments or other than to waive any condition). The
Stockholder shall give Purchaser at least two business days' prior notice of any
withdrawal of Shares owned by the Stockholder pursuant to the immediately
preceding proviso.

         SECTION 1.2. Option. (a) The Stockholder hereby irrevocably grants
Parent an option (the "Option"), exercisable only upon the events and subject to
the conditions set forth herein, to purchase any or all of the Shares at a
purchase price per share equal to $5.50 (or such higher per share price as may
be offered by Purchaser in the Offer).

         (b) Subject to the conditions set forth in Section 1.3 and the
termination provisions of Section 6.7, Parent may exercise the Option in whole
or in part at any time prior to the date 60 days after the expiration or
termination of the Offer (such sixtieth day being herein called the "Option
Expiration Date") if (x) the Stockholder fails to comply with any of its
obligations under this Agreement or withdraws the tender of the Shares except
under the circumstances set forth in the proviso to Section 1.1(b) (but the
Option shall not limit any other right or remedy available to the Parent or
Purchaser against the Stockholder for breach of this Agreement) or (y) the Offer
is not consummated because of the failure to satisfy any of the conditions to
the Offer set forth in Annex A to the Merger Agreement (other than as a result
of any action or inaction of the Parent or Purchaser which constitutes a breach
of the Merger Agreement).


                                       2
<PAGE>   33
                  Upon the occurrence of any of such circumstances, Purchaser
shall be entitled to exercise the Option and (subject to Section 1.3) Parent
shall be entitled to purchase the Shares and the Stockholder shall sell the
Shares to Parent. Parent shall exercise the Option by delivering written notice
thereof to the Stockholder (the "Notice"), specifying the number of Shares to be
purchased and the date, time and place for the closing of such purchase which
date shall not be less than three business days nor more than five business days
from the date the Stockholder receives the Notice and in no event shall such
date be later than the Option Expiration Date. The closing of the purchase of
Shares pursuant to this Section 1.2 (the "Closing") shall take place on the
date, at the time and at the place specified in such notice; provided, that if
at such date any of the conditions specified in Section 1.3 shall not have been
satisfied (or waived), Parent may postpone the Closing until a date within five
business days after such conditions are satisfied (but not later than the Option
Expiration Date).

         (c) At the Closing, the Stockholder will deliver to Parent (in
accordance with Parent's instructions) the certificates representing the Shares
owned by the Stockholder and being purchased pursuant to Section 1.2(c), duly
endorsed or accompanied by stock powers duly executed in blank. At such Closing,
Parent shall deliver to the Stockholder, by bank wire transfer of immediately
available funds, an amount equal to the number of Shares being purchased from
the Stockholder as specified in the Notice multiplied by $5.50 (or such higher
per share price as may be offered by Parent in the Offer).

         SECTION 1.3. Conditions to Option. The obligation of Parent to purchase
the Shares at the Closing is subject to the following conditions:

                  (a) all waiting periods under the Hart-Scott-Rodino Antitrust
         Improvements Act of 1976 and the rules and regulations promulgated
         thereunder (the "HSR Act") applicable to such purchase shall have
         expired or been terminated; and

                  (b) there shall be no preliminary or permanent injunction or
         other order, decree or ruling issued by any Governmental Body, nor any
         statute, rule, regulation or order promulgated or enacted by any
         Governmental Body prohibiting, or otherwise restraining, such purchase.

         SECTION 1.4. No Purchase. Purchaser and Parent may allow the Offer to
expire without accepting for payment or paying for any Shares, on the terms and
conditions set forth in the Offer to Purchase, and may allow the Option to
expire without exercising the Option and purchasing all or any Shares pursuant
to such exercise. If all Shares validly tendered and not withdrawn are not
accepted for payment and paid for in accordance with the terms of the Offer to
Purchase or pursuant to the exercise of the Option, they shall be returned to
the Stockholder, whereupon they shall continue to be held by the Stockholder

covenants and agrees that:

                  (a) No Solicitation. The Stockholder shall not directly or

         recapitalization, combinations, conversions, exchanges of shares,
         extraordinary or liquidating dividends, or other changes in the
         corporate or capital structure of the Company which would have the
         effect of diluting or changing Parent and Purchaser's rights hereunder,
         the number and kind of shares or securities subject to this Agreement
         and the price set forth herein at which Shares may be purchased from
         the Stockholder pursuant to the Offer or the exercise of the Option
         shall be appropriately and equitably adjusted so that Parent and
         Purchaser shall receive pursuant to the Offer or the exercise of the
         Option the number and class of shares or other securities or property
         that Parent or Purchaser, as the case may be, would have received in
         respect of the Shares purchasable pursuant to the Offer or the exercise
         of the Option if such purchase had occurred immediately prior to such
         event.

         SECTION 6.7. Amendments; Termination. This Agreement may not be
modified, amended, altered or supplemented, except upon the execution and
delivery of a written agreement executed by the parties hereto. Notwithstanding
anything herein to the contrary, this Agreement shall expire and be of no
further force or effect if (i) the conditions to the Purchaser's obligations to
accept for payment and pay for Shares pursuant to the Offer shall have been
satisfied and the Purchaser breaches any obligation of Purchaser under the
Merger Agreement to accept for payment and promptly pay for all Shares validly

provided further that except as set forth in the prior clause, a party may not
assign, delegate or otherwise transfer any of its rights or obligations under
this Agreement without the consent of the other parties hereto and any purported
assignment, delegation or transfer without such consent shall be null and void.

         SECTION 6.9. Governing Law. This Agreement shall be construed in

principles of conflicts of laws thereof.

         SECTION 6.10. Counterparts; Effectiveness. This Agreement may be signed

effects as if the signatures


                                       8
<PAGE>   39
thereto and thereof were upon the same instrument. This Agreement shall become
effective when each party hereto shall have received counterparts hereof signed
by all of the other parties hereto.

         SECTION 6.11. Stockholder Capacity. The Stockholder signs solely in its
capacity as the record holder and beneficial owner of the Shares and nothing
herein shall limit or affect any actions taken by the Stockholder in his or her
capacity as an officer, director, partner, employee or affiliate of the Company
and no such actions shall be deemed a breach of this Agreement.

         SECTION 6.12. Severability. If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of law,
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions contemplated hereby are not affected in any manner
materially adverse to any party. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the parties as closely as possible in a mutually acceptable manner in
order that the transactions be consummated as originally contemplated to the
fullest extent possible. To the extent that any provision of this Agreement and
the Merger Agreement conflict, the provisions of the Merger Agreement shall
control.

among Fedders Corporation, a Delaware corporation (the "Parent"), TI Acquisition
Corp., a Pennsylvania corporation and an indirect wholly owned subsidiary of the
Parent ("Purchaser"), and F. Trent Hill, Jr. (the "Stockholder").

         WHEREAS, concurrently with the execution and delivery of this Agreement
the Parent, Purchaser and Trion, Inc., a Pennsylvania corporation (the
"Company"), have entered into an Agreement and Plan of Merger dated as of the
date hereof (such Agreement and Plan of Merger, as amended from time to time,
the "Merger Agreement"), which provides, among other things, that Purchaser

Agreement (any term used herein without definition shall have the definition
ascribed thereto in the Merger Agreement);

         WHEREAS, the Stockholder owns beneficially and of record shares of
Company Common Stock (such shares of Company Common Stock being collectively
referred to herein as the "Stockholder Shares"); and

         WHEREAS, as a condition to the willingness of the Parent and Purchaser
to enter into the Merger Agreement, and as an inducement to them to do so, the
Stockholder has agreed for the benefit of the Parent and Purchaser to tender the
Stockholder Shares and any other shares of Company Common Stock at any time

Stock owned by the Stockholder in favor of the Merger, and to grant to Parent an
option to acquire all Stockholder Shares and all other shares of Company Common
Stock owned by the Stockholder under certain circumstances, all on the terms and
conditions contained in this Agreement.

         NOW, THEREFORE, in consideration of the representations, warranties,
covenants and agreements contained in this Agreement, the parties hereby agree
as follows:
<PAGE>   42
                                    ARTICLE I

                             Tender Offer and Option

         SECTION 1.1. Tender of Shares. (a) Within five business days of the
commencement by Purchaser of the Offer, the Stockholder shall tender to the
Depository designated in the Offer to Purchase (the "Offer to Purchase")
distributed by Purchaser in connection with the Offer (i) a letter of
transmittal with respect to the Stockholder Shares and any other shares of
Company Common Stock held by the Stockholder (whether or not currently held by
the Stockholder; the Stockholder Shares, together with any shares acquired by
the Stockholder in any capacity after the date hereof and prior to the
termination of this Agreement whether upon the exercise of options, warrants or
rights, the conversion or exchange of convertible or exchangeable securities, or
by means of purchase, dividend, distribution or otherwise (the "Shares")),
complying with the terms of the Offer to Purchase, (ii) the certificates
representing the Shares, and (iii) all other documents or instruments required
to be delivered pursuant to the terms of the Offer to Purchase.

         (b) The Stockholder shall not, subject to applicable law, withdraw the
tender effected in accordance with Section 1.1(a); provided, however, that the
Stockholder may decline to tender, or may withdraw, any and all Shares owned by
the Stockholder if the Purchaser amends the Offer to (w) reduce the Offer Price
to less than $5.50 in cash, net to the stockholders, (x) reduce the number of
shares of Company Common Stock subject to the Offer, (y) change the form of
consideration payable in the Offer or (z) amend or modify any term or condition
of the Offer in a manner adverse to the stockholders of the Company (other than
insignificant changes or amendments or other than to waive any condition). The
Stockholder shall give Purchaser at least two business days' prior notice of any
withdrawal of Shares owned by the Stockholder pursuant to the immediately
preceding proviso.

         SECTION 1.2. Option. (a) The Stockholder hereby irrevocably grants
Parent an option (the "Option"), exercisable only upon the events and subject to
the conditions set forth herein, to purchase any or all of the Shares at a
purchase price per share equal to $5.50 (or such higher per share price as may
be offered by Purchaser in the Offer).

         (b) Subject to the conditions set forth in Section 1.3 and the
termination provisions of Section 6.7, Parent may exercise the Option in whole
or in part at any time prior to the date 60 days after the expiration or
termination of the Offer (such sixtieth day being herein called the "Option
Expiration Date") if (x) the Stockholder fails to comply with any of its
obligations under this Agreement or withdraws the tender of the Shares except
under the circumstances set forth in the proviso to Section 1.1(b) (but the
Option shall not limit any other right or remedy available to the Parent or
Purchaser against the Stockholder for breach of this Agreement) or (y) the Offer
is not consummated because of the failure to satisfy any of the conditions to
the Offer set forth in Annex A to the Merger Agreement (other than as a result
of any action or inaction of the Parent or Purchaser which constitutes a breach
of the Merger Agreement).


                                       2
<PAGE>   43
                  Upon the occurrence of any of such circumstances, Purchaser
shall be entitled to exercise the Option and (subject to Section 1.3) Parent
shall be entitled to purchase the Shares and the Stockholder shall sell the
Shares to Parent. Parent shall exercise the Option by delivering written notice
thereof to the Stockholder (the "Notice"), specifying the number of Shares to be
purchased and the date, time and place for the closing of such purchase which
date shall not be less than three business days nor more than five business days
from the date the Stockholder receives the Notice and in no event shall such
date be later than the Option Expiration Date. The closing of the purchase of
Shares pursuant to this Section 1.2 (the "Closing") shall take place on the
date, at the time and at the place specified in such notice; provided, that if
at such date any of the conditions specified in Section 1.3 shall not have been
satisfied (or waived), Parent may postpone the Closing until a date within five
business days after such conditions are satisfied (but not later than the Option
Expiration Date).

         (c) At the Closing, the Stockholder will deliver to Parent (in
accordance with Parent's instructions) the certificates representing the Shares
owned by the Stockholder and being purchased pursuant to Section 1.2(c), duly
endorsed or accompanied by stock powers duly executed in blank. At such Closing,
Parent shall deliver to the Stockholder, by bank wire transfer of immediately
available funds, an amount equal to the number of Shares being purchased from
the Stockholder as specified in the Notice multiplied by $5.50 (or such higher
per share price as may be offered by Parent in the Offer).

         SECTION 1.3. Conditions to Option. The obligation of Parent to purchase
the Shares at the Closing is subject to the following conditions:

                  (a) all waiting periods under the Hart-Scott-Rodino Antitrust
         Improvements Act of 1976 and the rules and regulations promulgated
         thereunder (the "HSR Act") applicable to such purchase shall have
         expired or been terminated; and

                  (b) there shall be no preliminary or permanent injunction or
         other order, decree or ruling issued by any Governmental Body, nor any
         statute, rule, regulation or order promulgated or enacted by any
         Governmental Body prohibiting, or otherwise restraining, such purchase.

         SECTION 1.4. No Purchase. Purchaser and Parent may allow the Offer to
expire without accepting for payment or paying for any Shares, on the terms and
conditions set forth in the Offer to Purchase, and may allow the Option to
expire without exercising the Option and purchasing all or any Shares pursuant
to such exercise. If all Shares validly tendered and not withdrawn are not
accepted for payment and paid for in accordance with the terms of the Offer to
Purchase or pursuant to the exercise of the Option, they shall be returned to
the Stockholder, whereupon they shall continue to be held by the Stockholder
subject to the terms and conditions of this Agreement.

binding on the Stockholder or result in the imposition of any Lien on any assets

covenants and agrees that:

                  (a) No Solicitation. The Stockholder shall not directly or

         recapitalization, combinations, conversions, exchanges of shares,
         extraordinary or liquidating dividends, or other changes in the
         corporate or capital structure of the Company which would have the
         effect of diluting or changing Parent and Purchaser's rights hereunder,
         the number and kind of shares or securities subject to this Agreement
         and the price set forth herein at which Shares may be purchased from
         the Stockholder pursuant to the Offer or the exercise of the Option
         shall be appropriately and equitably adjusted so that Parent and
         Purchaser shall receive pursuant to the Offer or the exercise of the
         Option the number and class of shares or other securities or property
         that Parent or Purchaser, as the case may be, would have received in
         respect of the Shares purchasable pursuant to the Offer or the exercise
         of the Option if such purchase had occurred immediately prior to such
         event.


                                   ARTICLE VI

to consummate and make effective the transactions contemplated by this
Agreement.

         SECTION 6.4. Specific Performance. The parties acknowledge and agree
that performance of their respective obligations hereunder will confer a unique
benefit on the other and that a failure of performance will not be compensable

<PAGE>   48

Stockholder for any breach by the other party or parties of any agreement,
covenant or representation hereunder.

         SECTION 6.5. Notices. All notices, requests, claims, demands and other
communications hereunder shall be deemed to have been duly given when delivered

the representations and warranties contained in this Agreement shall survive the

         SECTION 6.7. Amendments; Termination. This Agreement may not be
modified, amended, altered or supplemented, except upon the execution and
delivery of a written agreement executed by the parties hereto. Notwithstanding
anything herein to the contrary, this Agreement shall expire and be of no
further force or effect if (i) the conditions to the Purchaser's obligations to
accept for payment and pay for Shares pursuant to the Offer shall have been
satisfied and the Purchaser breaches any obligation of Purchaser under the
Merger Agreement to accept for payment and promptly pay for all Shares validly
tendered and not withdrawn pursuant to the Offer upon expiration of the Offer or

         SECTION 6.8. Successors and Assigns. The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns; provided, however, that Purchaser may assign

which is the assignee of Purchaser's rights under the Merger Agreement; and
provided further that except as set forth in the prior clause, a party may not
assign, delegate or otherwise transfer any of its rights or obligations under
this Agreement without the consent of the other parties hereto and any purported
assignment, delegation or transfer without such consent shall be null and void.

         SECTION 6.9. Governing Law. This Agreement shall be construed in
accordance with and governed by the law of Delaware without giving effect to the
principles of conflicts of laws thereof.

         SECTION 6.10. Counterparts; Effectiveness. This Agreement may be signed

effects as if the signatures

                                        8
<PAGE>   49
thereto and thereof were upon the same instrument. This Agreement shall become
effective when each party hereto shall have received counterparts hereof signed
by all of the other parties hereto.

         SECTION 6.11. Stockholder Capacity. The Stockholder signs solely in its
capacity as the record holder and beneficial owner of the Shares and nothing
herein shall limit or affect any actions taken by the Stockholder in his or her
capacity as an officer, director, partner, employee or affiliate of the Company
and no such actions shall be deemed a breach of this Agreement.

         SECTION 6.12. Severability. If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of law,
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions contemplated hereby are not affected in any manner
materially adverse to any party. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the parties as closely as possible in a mutually acceptable manner in
order that the transactions be consummated as originally contemplated to the
fullest extent possible. To the extent that any provision of this Agreement and
the Merger Agreement conflict, the provisions of the Merger Agreement shall
control.

among Fedders Corporation, a Delaware corporation (the "Parent"), TI Acquisition
Corp., a Pennsylvania corporation and an indirect wholly owned subsidiary of the
Parent ("Purchaser"), and Grant R.
Meyers (the "Stockholder").

         WHEREAS, concurrently with the execution and delivery of this Agreement
the Parent, Purchaser and Trion, Inc., a Pennsylvania corporation (the
"Company"), have entered into an Agreement and Plan of Merger dated as of the
date hereof (such Agreement and Plan of Merger, as amended from time to time,
the "Merger Agreement"), which provides, among other things, that Purchaser
shall make the Offer (as defined in the Merger Agreement) to purchase at a price
of $5.50 per share, net to the sellers in cash, all of the issued and
outstanding shares of the Company's Common Stock, par value $0.50 per share (the
"Company Common Stock"), and shall merge with and into the Company (the
"Merger"), upon the terms and subject to the conditions set forth in the Merger
Agreement (any term used herein without definition shall have the definition
ascribed thereto in the Merger Agreement);

         WHEREAS, the Stockholder owns beneficially and of record shares of
Company Common Stock (such shares of Company Common Stock being collectively
referred to herein as the "Stockholder Shares"); and

         WHEREAS, as a condition to the willingness of the Parent and Purchaser
to enter into the Merger Agreement, and as an inducement to them to do so, the
Stockholder has agreed for the benefit of the Parent and Purchaser to tender the
Stockholder Shares and any other shares of Company Common Stock at any time
during the term of this Agreement held by the Stockholder, pursuant to the
Offer, to vote all the Stockholder Shares and any other shares of Company Common
Stock owned by the Stockholder in favor of the Merger, and to grant to Parent an
option to acquire all Stockholder Shares and all other shares of Company Common
Stock owned by the Stockholder under certain circumstances, all on the terms and
conditions contained in this Agreement.

         NOW, THEREFORE, in consideration of the representations, warranties,
covenants and agreements contained in this Agreement, the parties hereby agree
as follows:
<PAGE>   52
                                    ARTICLE I

                             Tender Offer and Option

         SECTION 1.1. Tender of Shares. (a) Within five business days of the
commencement by Purchaser of the Offer, the Stockholder shall tender to the
Depository designated in the Offer to Purchase (the "Offer to Purchase")
distributed by Purchaser in connection with the Offer (i) a letter of
transmittal with respect to the Stockholder Shares and any other shares of
Company Common Stock held by the Stockholder (whether or not currently held by
the Stockholder; the Stockholder Shares, together with any shares acquired by
the Stockholder in any capacity after the date hereof and prior to the
termination of this Agreement whether upon the exercise of options, warrants or
rights, the conversion or exchange of convertible or exchangeable securities, or
by means of purchase, dividend, distribution or otherwise (the "Shares")),
complying with the terms of the Offer to Purchase, (ii) the certificates
representing the Shares, and (iii) all other documents or instruments required
to be delivered pursuant to the terms of the Offer to Purchase.

         (b) The Stockholder shall not, subject to applicable law, withdraw the
tender effected in accordance with Section 1.1(a); provided, however, that the
Stockholder may decline to tender, or may withdraw, any and all Shares owned by
the Stockholder if the Purchaser amends the Offer to (w) reduce the Offer Price
to less than $5.50 in cash, net to the stockholders, (x) reduce the number of
shares of Company Common Stock subject to the Offer, (y) change the form of
consideration payable in the Offer or (z) amend or modify any term or condition
of the Offer in a manner adverse to the stockholders of the Company (other than
insignificant changes or amendments or other than to waive any condition). The
Stockholder shall give Purchaser at least two business days' prior notice of any
withdrawal of Shares owned by the Stockholder pursuant to the immediately
preceding proviso.

         SECTION 1.2. Option. (a) The Stockholder hereby irrevocably grants
Parent an option (the "Option"), exercisable only upon the events and subject to
the conditions set forth herein, to purchase any or all of the Shares at a
purchase price per share equal to $5.50 (or such higher per share price as may
be offered by Purchaser in the Offer).

         (b) Subject to the conditions set forth in Section 1.3 and the
termination provisions of Section 6.7, Parent may exercise the Option in whole
or in part at any time prior to the date 60 days after the expiration or
termination of the Offer (such sixtieth day being herein called the "Option
Expiration Date") if (x) the Stockholder fails to comply with any of its
obligations under this Agreement or withdraws the tender of the Shares except
under the circumstances set forth in the proviso to Section 1.1(b) (but the
Option shall not limit any other right or remedy available to the Parent or
Purchaser against the Stockholder for breach of this Agreement) or (y) the Offer
is not consummated because of the failure to satisfy any of the conditions to
the Offer set forth in Annex A to the Merger Agreement (other than as a result
of any action or inaction of the Parent or Purchaser which constitutes a breach
of the Merger Agreement).

                                        2
<PAGE>   53
                  Upon the occurrence of any of such circumstances, Purchaser
shall be entitled to exercise the Option and (subject to Section 1.3) Parent
shall be entitled to purchase the Shares and the Stockholder shall sell the
Shares to Parent. Parent shall exercise the Option by delivering written notice
thereof to the Stockholder (the "Notice"), specifying the number of Shares to be
purchased and the date, time and place for the closing of such purchase which
date shall not be less than three business days nor more than five business days
from the date the Stockholder receives the Notice and in no event shall such
date be later than the Option Expiration Date. The closing of the purchase of
Shares pursuant to this Section 1.2 (the "Closing") shall take place on the
date, at the time and at the place specified in such notice; provided, that if
at such date any of the conditions specified in Section 1.3 shall not have been
satisfied (or waived), Parent may postpone the Closing until a date within five
business days after such conditions are satisfied (but not later than the Option
Expiration Date).

         (c) At the Closing, the Stockholder will deliver to Parent (in
accordance with Parent's instructions) the certificates representing the Shares
owned by the Stockholder and being purchased pursuant to Section 1.2(c), duly
endorsed or accompanied by stock powers duly executed in blank. At such Closing,
Parent shall deliver to the Stockholder, by bank wire transfer of immediately
available funds, an amount equal to the number of Shares being purchased from
the Stockholder as specified in the Notice multiplied by $5.50 (or such higher
per share price as may be offered by Parent in the Offer).

         SECTION 1.3. Conditions to Option. The obligation of Parent to purchase
the Shares at the Closing is subject to the following conditions:

                  (a) all waiting periods under the Hart-Scott-Rodino Antitrust
         Improvements Act of 1976 and the rules and regulations promulgated
         thereunder (the "HSR Act") applicable to such purchase shall have
         expired or been terminated; and

                  (b) there shall be no preliminary or permanent injunction or
         other order, decree or ruling issued by any Governmental Body, nor any
         statute, rule, regulation or order promulgated or enacted by any
         Governmental Body prohibiting, or otherwise restraining, such purchase.

         SECTION 1.4. No Purchase. Purchaser and Parent may allow the Offer to
expire without accepting for payment or paying for any Shares, on the terms and
conditions set forth in the Offer to Purchase, and may allow the Option to
expire without exercising the Option and purchasing all or any Shares pursuant
to such exercise. If all Shares validly tendered and not withdrawn are not
accepted for payment and paid for in accordance with the terms of the Offer to
Purchase or pursuant to the exercise of the Option, they shall be returned to
the Stockholder, whereupon they shall continue to be held by the Stockholder
subject to the terms and conditions of this Agreement.

         recapitalization, combinations, conversions, exchanges of shares,
         extraordinary or liquidating dividends, or other changes in the
         corporate or capital structure of the Company which would have the
         effect of diluting or changing Parent and Purchaser's rights hereunder,

         and the price set forth herein at which Shares may be purchased from
         the Stockholder pursuant to the Offer or the exercise of the Option

         Option the number and class of shares or other securities or property
         that Parent or Purchaser, as the case may be, would have received in
         respect of the Shares purchasable pursuant to the Offer or the exercise
         of the Option if such purchase had occurred immediately prior to such
         event.


                                   ARTICLE VI

to consummate and make effective the transactions contemplated by this
Agreement.

         SECTION 6.4. Specific Performance. The parties acknowledge and agree

<PAGE>   58

         SECTION 6.6. Survival of Representations and Warranties. All
representations and warranties contained in this Agreement shall survive

the representations and warranties contained in this Agreement shall survive the

         SECTION 6.7. Amendments; Termination. This Agreement may not be
modified, amended, altered or supplemented, except upon the execution and
delivery of a written agreement executed by the parties hereto. Notwithstanding
anything herein to the contrary, this Agreement shall expire and be of no
further force or effect if (i) the conditions to the Purchaser's obligations to
accept for payment and pay for Shares pursuant to the Offer shall have been
satisfied and the Purchaser breaches any obligation of Purchaser under the
Merger Agreement to accept for payment and promptly pay for all Shares validly
tendered and not withdrawn pursuant to the Offer upon expiration of the Offer or

provided further that except as set forth in the prior clause, a party may not
assign, delegate or otherwise transfer any of its rights or obligations under
this Agreement without the consent of the other parties hereto and any purported
assignment, delegation or transfer without such consent shall be null and void.

         SECTION 6.9. Governing Law. This Agreement shall be construed in
accordance with and governed by the law of Delaware without giving effect to the
principles of conflicts of laws thereof.

         SECTION 6.10. Counterparts; Effectiveness. This Agreement may be signed

effects as if the signatures

                                        8
<PAGE>   59
thereto and thereof were upon the same instrument. This Agreement shall become
effective when each party hereto shall have received counterparts hereof signed
by all of the other parties hereto.

         SECTION 6.11. Stockholder Capacity. The Stockholder signs solely in its
capacity as the record holder and beneficial owner of the Shares and nothing
herein shall limit or affect any actions taken by the Stockholder in his or her
capacity as an officer, director, partner, employee or affiliate of the Company
and no such actions shall be deemed a breach of this Agreement.

         SECTION 6.12. Severability. If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of law,
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions contemplated hereby are not affected in any manner
materially adverse to any party. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the parties as closely as possible in a mutually acceptable manner in
order that the transactions be consummated as originally contemplated to the
fullest extent possible. To the extent that any provision of this Agreement and
the Merger Agreement conflict, the provisions of the Merger Agreement shall
control.

         SECTION 6.13. Pledged Shares. Notwithstanding anything to the contrary
herein, in the event this Agreement conflicts with any agreement or
understanding governing any of the 185,292 Shares pledged to Wachovia Bank,
N.A., String & Strongfellow or Hugh E. Carr (the "Pledge Agreements"), the
Pledge Agreements shall control.

Expiration Date") if (x) the Stockholder fails to comply with any of its
obligations under this Agreement or withdraws the tender of the Shares except
under the circumstances set forth in the proviso to Section 1.1(b) (but the
Option shall not limit any other right or remedy available to the Parent or
Purchaser against the Stockholder for breach of this Agreement) or (y) the Offer

the Offer set forth in Annex A to the Merger Agreement (other than as a result
of any action or inaction of the Parent or Purchaser which constitutes a breach
of the Merger Agreement).

         Upon the occurrence of any of such circumstances, Purchaser shall be
entitled to exercise the Option and (subject to Section 1.3) Parent shall be
entitled to purchase the Shares and the Stockholder shall sell the Shares to
Parent. Parent shall exercise the Option by delivering written notice thereof to
the Stockholder (the "Notice"), specifying the number of Shares to be purchased
and the date, time and place for the closing of such purchase which date shall
not be less than three business days nor more than five business days from the
date the Stockholder receives the Notice and in no event shall such date be
later than the Option Expiration Date. The closing of the purchase of Shares
pursuant to this Section 1.2 (the "Closing") shall take place on the date, at
the time and at the place specified in such notice; provided, that if at such
date any of the conditions specified in Section 1.3 shall not have been
satisfied (or waived), Parent may postpone the Closing until a date within five
business days after such conditions are satisfied (but not later than the Option
Expiration Date).

         (c) At the Closing, the Stockholder will deliver to Parent (in
accordance with Parent's instructions) the certificates representing the Shares
owned by the Stockholder and being purchased pursuant to Section 1.2(c), duly
endorsed or accompanied by stock powers duly executed in blank. At such Closing,
Parent shall deliver to the Stockholder, by bank wire transfer of immediately
available funds, an amount equal to the number of Shares being purchased from
the Stockholder as specified in the Notice multiplied by $5.50 (or such higher
per share price as may be offered by Parent in the Offer).

         SECTION 1.3. Conditions to Option. The obligation of Parent to purchase
the Shares at the Closing is subject to the following conditions:

                  (a) all waiting periods under the Hart-Scott-Rodino Antitrust
         Improvements Act of 1976 and the rules and regulations promulgated
         thereunder (the "HSR Act") applicable to such purchase shall have
         expired or been terminated; and

                  (b) there shall be no preliminary or permanent injunction or
         other order, decree or ruling issued by any Governmental Body, nor any
         statute, rule, regulation or order promulgated or enacted by any
         Governmental Body prohibiting, or otherwise restraining, such purchase.

         SECTION 1.4. No Purchase. Purchaser and Parent may allow the Offer to
expire without accepting for payment or paying for any Shares, on the terms and
conditions set forth in the Offer to Purchase, and may allow the Option to
expire without exercising the Option and purchasing all or any Shares pursuant
to such exercise. If all Shares validly tendered and not withdrawn are not
accepted for payment and paid for in accordance with the terms of the Offer to
Purchase or pursuant to the exercise of the Option, they shall be returned to
the Stockholder, whereupon they shall continue to be held by the Stockholder
subject to the terms and conditions of this Agreement.

the Shares, (ii) enter into any contract, option, put, call, "collar" or other
agreement or understanding with respect to any Transfer of any or all of the

         or securities subject to this Agreement and the price set forth herein
         at which Shares may be purchased from the Stockholder pursuant to the
         Offer or the exercise of the Option shall be appropriately and
         equitably adjusted so that Parent and Purchaser shall receive pursuant
         to the Offer or the exercise of the Option the number and class of
         shares or other securities or property that Parent or Purchaser, as the
         case may be, would have received in respect of the Shares purchasable

Parent an option (the "Option"), exercisable only upon the events and subject to
the conditions set forth herein, to purchase any or all of the Shares at a
purchase price per share equal to $5.50 (or such higher per share price as may
be offered by Purchaser in the Offer).

         (b) Subject to the conditions set forth in Section 1.3 and the
termination provisions of Section 6.7, Parent may exercise the Option in whole
or in part at any time prior to the date 60 days after the expiration or
termination of the Offer (such sixtieth day being herein called the "Option
Expiration Date") if (x) the Stockholder fails to comply with any of its
obligations under this Agreement or withdraws the tender of the Shares except
under the circumstances set forth in the proviso to Section 1.1(b) (but the
Option shall not limit any other right or remedy available to the Parent or
Purchaser against the Stockholder for breach of this Agreement) or (y) the Offer
is not consummated because of the failure to satisfy any of the conditions to
the Offer set forth in Annex A to the Merger Agreement (other than as a result
of any action or inaction of the Parent or Purchaser which constitutes a breach
of the Merger Agreement).

         Upon the occurrence of any of such circumstances, Purchaser shall be
entitled to exercise the Option and (subject to Section 1.3) Parent shall be
entitled to purchase the Shares and the Stockholder shall sell the Shares to
Parent. Parent shall exercise the Option by delivering written notice thereof to
the Stockholder (the "Notice"), specifying the number of Shares to be purchased
and the date, time and place for the closing of such purchase which date shall
not be less than three business days nor more than five business days from the
date the Stockholder receives the Notice and in no event shall such date be
later than the Option Expiration Date. The closing of the purchase of Shares
pursuant to this Section 1.2 (the "Closing") shall take place on the date, at
the time and at the place specified in such notice; provided, that if at such
date any of the conditions specified in Section 1.3 shall not have been
satisfied (or waived), Parent may postpone the Closing until a date within five
business days after such conditions are satisfied (but not later than the Option
Expiration Date).

         (c) At the Closing, the Stockholder will deliver to Parent (in
accordance with Parent's instructions) the certificates representing the Shares
owned by the Stockholder and being purchased pursuant to Section 1.2(c), duly
endorsed or accompanied by stock powers duly executed in blank. At such Closing,
Parent shall deliver to the Stockholder, by bank wire transfer of immediately
available funds, an amount equal to the number of Shares being purchased from
the Stockholder as specified in the Notice multiplied by $5.50 (or such higher
per share price as may be offered by Parent in the Offer).

         SECTION 1.3. Conditions to Option. The obligation of Parent to purchase
the Shares at the Closing is subject to the following conditions:

                  (a) all waiting periods under the Hart-Scott-Rodino Antitrust
         Improvements Act of 1976 and the rules and regulations promulgated
         thereunder (the "HSR Act") applicable to such purchase shall have
         expired or been terminated; and

                  (b) there shall be no preliminary or permanent injunction or
         other order, decree or ruling issued by any Governmental Body, nor any
         statute, rule, regulation or order promulgated or enacted by any
         Governmental Body prohibiting, or otherwise restraining, such purchase.

         SECTION 1.4. No Purchase. Purchaser and Parent may allow the Offer to
expire without accepting for payment or paying for any Shares, on the terms and
conditions set forth in the Offer to Purchase, and may allow the Option to
expire without exercising the Option and purchasing all or any Shares pursuant
to such exercise. If all Shares validly tendered and not withdrawn are not
accepted for payment and paid for in accordance with the terms of the Offer to
Purchase or pursuant to the exercise of the Option, they shall be returned to
the Stockholder, whereupon they shall continue to be held by the Stockholder
subject to the terms and conditions of this Agreement.

         SECTION 3.1. (a) Ownership. As of the date hereof the Stockholder is
the sole, true, lawful and beneficial owner of 69,125 Shares and that there are
no restrictions on voting rights or rights of disposition pertaining to such

the Stockholder and being acquired pursuant to the Offer, the Merger or the
exercise of the Option, as the case may be, free and clear of any and all liens,
restrictions, security interests or any encumbrances whatsoever (collectively,
"Liens"). None of the Shares owned by the Stockholder is subject to any voting
trust or other agreement, arrangement or restriction with respect to the voting
of such Shares.

                      (b) Transfer of the Shares. (i) Until this Agreement is
terminated, the Stockholder shall not directly or indirectly offer to sell, sell
short, transfer (including gift), assign, pledge or otherwise dispose of or
transfer (each, a "Transfer") any interest in or encumber with any Lien any of
the Shares, (ii) enter into any contract, option, put, call, "collar" or other
agreement or understanding with respect to any Transfer of any or all of the
Shares or any interest therein; (iii) grant any proxy, power-of-attorney or
other authorization or consent in or with respect to the Shares; (iv) deposit
the Shares into a voting trust or enter into a voting agreement or arrangement
with respect to the Shares; or (v) take any other action with respect to the
Shares that would in any way restrict, limit or interfere with the performance
of its obligations hereunder.

                      (c) The Stockholder agrees to place the following legend
on any and all certificates evidencing the Shares:

                  THE SHARES OF COMMON STOCK REPRESENTED BY THIS CERTIFICATE ARE
                  SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER PURSUANT TO THAT
                  SHAREHOLDER AGREEMENT, DATED AS OF JULY 12, 1999, BY AND AMONG
                  PARENT, PURCHASER AND STOCKHOLDER. ANY TRANSFER OF SUCH SHARES
                  OF COMMON STOCK IN VIOLATION OF THE TERMS OF SUCH AGREEMENT
                  SHALL BE NULL AND VOID AND OF NO EFFECT WHATSOEVER.

and performance by the Stockholder of this Agreement and the consummation of the
transactions contemplated hereby (i) are within the Stockholder's power and
authority, have been duly authorized by all necessary action (including any

require no action by or in respect of, or filing with, any Governmental Body
(except as may be required under the HSR Act and under the Securities Exchange
Act of 1934, as amended, and the rules and regulations promulgated thereunder
(the "Exchange Act")), and (iii) do not and will not contravene or constitute a
default under, or give rise to a right of termination, cancellation or
acceleration of any right or obligation of the Stockholder or to a loss of any
benefit of the Stockholder under, any provision of applicable law or regulation
or any agreement, judgment, injunction, order, decree, or other instrument
binding on the Stockholder or result in the imposition of any Lien on any assets
of the Stockholder. If the Stockholder is married and the Shares constitute
community property or otherwise are owned or held in a manner that requires
spousal or other approval for this Agreement to be legal, valid and binding,
this Agreement has been duly consented to and delivered by the Stockholder's
spouse or the person giving such approval, enforceable against such spouse or
person in accordance with its terms.

         SECTION 3.3. Binding Effect. This Agreement has been duly executed and
delivered by the Stockholder and is the valid and binding agreement of the

similar laws relating to creditors' rights generally.

         SECTION 3.4. Total Shares. The Stockholder Shares owned by the
Stockholder are the only shares of Company Common Stock beneficially owned as of
the date hereof by the Stockholder and the Stockholder has no option to purchase
or right to subscribe for or otherwise acquire any securities of the Company and
has no other interest in or voting rights with respect to any other securities
of the Company.

         SECTION 3.5. Finder's Fees. No investment banker, broker or finder is
entitled to a commission or fee from Purchaser or the Company in respect of this
Agreement based upon any arrangement or agreement made by or on behalf of the
Stockholder, except as otherwise disclosed in the Merger Agreement.

acquired upon consummation of the Offer, or upon exercise of the Option will be
acquired by Parent for its own account and not with a view to the public
distribution thereof and will not be transferred except in compliance with the
Securities Act and the rules and regulations promulgated thereunder.


                                    ARTICLE V

         SECTION 5.1. Agreements of Stockholder. The Stockholder hereby
covenants and agrees that:

                  (a) No Solicitation. The Stockholder shall not directly or
         indirectly (i) solicit, initiate or knowingly encourage (or authorize
         any person to solicit, initiate or encourage) any Acquisition Proposal,
         or (ii) participate in any discussion or negotiations regarding, or
         furnish to any other person any information with respect to, or
         otherwise knowingly cooperate in any way with, or participate in,
         facilitate or encourage any effort or attempt by any other person to do
         or seek the foregoing. The Stockholder shall promptly advise the
         Purchaser of the terms of any communications it or any of its
         affiliates may receive relating

<PAGE>   77

         to any Acquisition Proposal (including, without limitation, the
         identify of the party making any such Acquisition Proposal).

                  (b) Adjustment upon Changes in Capitalization or Merger. In
         the event of any change in the Company's capital stock by reason of
         stock dividends, stock splits, mergers, consolidations,
         recapitalization, combinations, conversions, exchanges of shares,
         extraordinary or liquidating dividends, or other changes in the
         corporate or capital structure of the Company which would have the
         effect of diluting or changing Parent and Purchaser's rights hereunder,
         the number and kind of shares or securities subject to this Agreement
         and the price set forth herein at which Shares may be purchased from
         the Stockholder pursuant to the Offer or the exercise of the Option
         shall be appropriately and equitably adjusted so that Parent and
         Purchaser shall receive pursuant to the Offer or the exercise of the
         Option the number and class of shares or other securities or property
         that Parent or Purchaser, as the case may be, would have received in
         respect of the Shares purchasable pursuant to the Offer or the exercise
         of the Option if such purchase had occurred immediately prior to such
         event.

                                   ARTICLE VI

         SECTION 6.1. Expenses. All costs and expenses incurred in connection

further documents and instruments and use its reasonable best efforts to secure
such consents and take all such further action as may be reasonably necessary in
order to consummate the transactions contemplated hereby and by the Merger
Agreement.

         SECTION 6.3. Additional Agreements. Subject to the terms and conditions
of this Agreement, each of the parties hereto agrees to use all reasonable best
efforts to take, or cause to be taken, all actions and to do, or cause to be
done, all things necessary, proper or advisable under applicable laws and
regulations and which may be required under any agreements, contracts,
commitments, instruments, understandings, arrangements or restrictions of any
kind to which such party is a party or by which such party is governed or bound,
to consummate and make effective the transactions contemplated by this
Agreement.

         SECTION 6.4. Specific Performance. The parties acknowledge and agree
that performance of their respective obligations hereunder will confer a unique
benefit on the other and that a failure of performance will not be compensable
by money damages. The parties therefore agree that this Shareholder Agreement
shall be specifically enforceable and that specific enforcement


                                        7
<PAGE>   78

and injunctive relief shall be available to the Parent, Purchaser or the
Stockholder for any breach by the other party or parties of any agreement,
covenant or representation hereunder.

         SECTION 6.5. Notices. All notices, requests, claims, demands and other
communications hereunder shall be deemed to have been duly given when delivered
in person, by telecopy, or by registered or certified mail (postage prepaid,

signature page hereto.

         SECTION 6.6. Survival of Representations and Warranties. All
representations and warranties contained in this Agreement shall survive

the representations and warranties contained in this Agreement shall survive the
acceptance for payment and payment for the Shares pursuant to the Offer.

         SECTION 6.7. Amendments; Termination. This Agreement may not be
modified, amended, altered or supplemented, except upon the execution and
delivery of a written agreement executed by the parties hereto. Notwithstanding
anything herein to the contrary, this Agreement shall expire and be of no
further force or effect if (i) the conditions to the Purchaser's obligations to
accept for payment and pay for Shares pursuant to the Offer shall have been
satisfied and the Purchaser breaches any obligation of Purchaser under the
Merger Agreement to accept for payment and promptly pay for all Shares validly
tendered and not withdrawn pursuant to the Offer upon expiration of the Offer or
(ii) Purchaser amends the Offer to (w) reduce the Offer Price to less than $5.50
in cash, net to the sellers, (x) reduce the number of shares of Company Common
Stock subject to the Offer, (y) change the form of consideration payable in the
Offer or (z) amend or modify any term or condition of the Offer in a manner
adverse to the stockholders of the Company (other than insignificant changes or
amendments or other than to waive any condition). This Agreement will also
terminate upon the earlier of (i) the close of business on March 1, 2000, or
(ii) the Effective Time.

         SECTION 6.8. Successors and Assigns. The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns; provided, however, that Purchaser may assign
its rights and obligations to another wholly-owned subsidiary of the Parent
which is the assignee of Purchaser's rights under the Merger Agreement; and
provided further that except as set forth in the prior clause, a party may not
assign, delegate or otherwise transfer any of its rights or obligations under
this Agreement without the consent of the other parties hereto and any purported
assignment, delegation or transfer without such consent shall be null and void.

         SECTION 6.9. Governing Law. This Agreement shall be construed in
accordance with and governed by the law of Delaware without giving effect to the
principles of conflicts of laws thereof.

         SECTION 6.10. Counterparts; Effectiveness. This Agreement may be signed
in any number of counterparts, each of which shall be an original, with the same
effects as if the signatures


                                        8
<PAGE>   79

thereto and thereof were upon the same instrument. This Agreement shall become
effective when each party hereto shall have received counterparts hereof signed
by all of the other parties hereto.

         SECTION 6.11. Stockholder Capacity. The Stockholder signs solely in its
capacity as the record holder and beneficial owner of the Shares and nothing
herein shall limit or affect any actions taken by the Stockholder in his or her
capacity as an officer, director, partner, employee or affiliate of the Company
and no such actions shall be deemed a breach of this Agreement.

         SECTION 6.12. Severability. If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of law,
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions contemplated hereby are not affected in any manner
materially adverse to any party. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the parties as closely as possible in a mutually acceptable manner in
order that the transactions be consummated as originally contemplated to the
fullest extent possible. To the extent that any provision of this Agreement and
the Merger Agreement conflict, the provisions of the Merger Agreement shall
control.

duly executed as of the day and year first above written.

To the Holders of Common Stock of
Trion, Inc.:

                                  INTRODUCTION

     TI Acquisition Corp., a Pennsylvania corporation ("Purchaser") and an
indirect wholly owned subsidiary of Fedders Corporation, a Delaware corporation
("Parent"), hereby offers to purchase all outstanding shares of common stock,
par value $0.50 per share (the "Shares"), of Trion, Inc., a Pennsylvania
corporation (the "Company"), at a price of $5.50 per Share, net to the seller in
cash, without interest (the "Offer Price"), upon the terms and subject to the
conditions set forth in this Offer to Purchase and in the related Letter of
Transmittal (which, as amended or supplemented from time to time, collectively
constitute the "Offer").

     Tendering shareholders of record who tender Shares directly will not be
obligated to pay brokerage fees or commissions or, except as set forth in
Instruction 6 of the Letter of Transmittal, stock transfer taxes on the purchase
of Shares by Purchaser pursuant to the Offer. Shareholders who hold their Shares
through a bank or broker should check with such institution as to whether they
charge any service fees. Purchaser will pay all fees and expenses of TM Capital
Corp. ("TM Capital"), which is acting as the Dealer Manager (in such capacity,
the "Dealer Manager"), American Stock Transfer and Trust Company which is acting
as the Depositary (in such capacity, the "Depositary") and D.F. King & Co., Inc.
("DF King"), which is acting as Information Agent (in such capacity, the
"Information Agent"), incurred in connection with the Offer and in accordance
with the terms of the agreements entered into between Purchaser and/or Parent
and each such person. See Section 16.

     THE BOARD OF DIRECTORS OF THE COMPANY (THE "COMPANY BOARD OF DIRECTORS") BY
A UNANIMOUS VOTE OF THOSE PRESENT AT THE MEETING APPROVED THE MERGER AGREEMENT
AND THE TRANSACTIONS CONTEMPLATED THEREBY, INCLUDING THE OFFER AND THE MERGER,
AND DETERMINED THAT THE OFFER AND THE MERGER ARE FAIR TO, AND IN THE BEST
INTERESTS OF, THE COMPANY'S SHAREHOLDERS AND RECOMMENDS THAT THE SHAREHOLDERS
ACCEPT THE OFFER AND TENDER THEIR SHARES PURSUANT TO THE OFFER.

     Harris Williams & Co. ("Harris Williams"), financial advisor to the
Company, has delivered to the Company Board of Directors its opinion, dated as
of July 12, 1999 (the "Financial Advisor Opinion"), to the effect that, as of
such date and based upon and subject to certain assumptions and matters stated
therein, the consideration to be received by the holders of Shares (other than
Parent and its affiliates if at all) in the Offer and the Merger was fair, from
a financial point of view, to such holders. A copy of the Financial Advisor
Opinion is attached as an exhibit to the Company's Solicitation/Recommendation
Statement on Schedule 14D-9 (the "Schedule 14D-9"), which has been filed by the
Company with the Securities and Exchange Commission (the "Commission") in
connection with the Offer and which is being mailed to holders of Shares
herewith. Holders of Shares are urged to, and should, read the Financial Advisor
Opinion carefully.

     THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE BEING VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION DATE THAT NUMBER OF SHARES
WHICH, WHEN ADDED TO THE SHARES BENEFICIALLY OWNED BY PARENT OR PURCHASER (IF
ANY), REPRESENTS AT LEAST 80% OF THE SHARES OUTSTANDING ON A FULLY DILUTED BASIS
ON THE DATE SHARES ARE ACCEPTED FOR PAYMENT (THE "MINIMUM CONDITION"). THE OFFER
IS ALSO SUBJECT TO THE OTHER CONDITIONS SET FORTH IN THIS OFFER TO PURCHASE. SEE
SECTION 14. As used in this Offer to Purchase, "fully diluted basis" takes into
account the exercise of all outstanding options and other rights and securities
exercisable into Shares. The Company has represented and warranted to Parent and
Purchaser that, as of July 12, 1999, there were 7,161,247 Shares issued and
outstanding and 391,524 Shares were issuable pursuant to the exercise of
outstanding options (the "Company Options"). The Merger Agreement provides,
among other things, that the Company will not, without the prior written consent
of Parent, change the authorized or issued capital stock of the Company or any
subsidiary of the Company, grant any stock option or right to purchase shares of
capital stock of the Company or any subsidiary of the Company, or issue any
security
<PAGE>   4

convertible into such capital stock. See Section 11. Based on the foregoing and
assuming the issuance of 391,524 Shares issuable upon the exercise of
outstanding Options, Purchaser believes that the Minimum Condition will be
satisfied if 6,042,217 Shares are validly tendered and not withdrawn prior to
the Expiration Date.

     The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of July 12, 1999 (the "Merger Agreement"), by and among Parent, Purchaser and
the Company. Pursuant to the Merger Agreement and the Pennsylvania Business
Corporation Law, as amended (the "PBCL"), as soon as practicable after the
completion of the Offer and satisfaction or waiver, if permissible, of all
conditions to the consummation of the Merger, including the purchase of Shares
pursuant to the Offer (sometimes referred to herein as the "consummation" of the
Offer) and the approval and adoption by the shareholders of the Company of (i)
an amendment to section 6 of the Company's articles of incorporation (the
"Articles Amendment") which amendment will delete the requirement in the
Company's articles of incorporation that a merger of the Company with an
existing shareholder or its affiliates receive the approval of a majority of the
shares not held by such shareholder and its affiliates, and (ii) the Merger
Agreement (if required by applicable law), Purchaser will be merged with and
into the Company (the "Merger") and the Company will be the surviving
corporation in the Merger (the "Surviving Corporation"). At the effective time
of the Merger (the "Effective Time"), each Share then outstanding, other than
Shares held by (i) the Company or any of its subsidiaries, (ii) Parent or any of
its subsidiaries including Purchaser, and (iii) shareholders who properly
perfect their dissenters' rights under the PBCL, will be converted into the
right to receive $5.50 in cash or any higher price per Share paid in the Offer
(the "Merger Consideration"), without interest. The Merger Agreement is more
fully described in Section 11.

     The Company has entered into a Stock Option Agreement, dated as of July 12,
1999 (the "Company Option Agreement"), with Parent and Purchaser pursuant to
which the Company has granted to Parent an irrevocable option (the "Stock
Option") to purchase up to the number of fully paid and nonassessable Shares
equal to 19.9% of the Shares issued and outstanding immediately prior to the
grant of the Stock Option, at a purchase price of $5.50 per Share, exercisable
upon the occurrence of certain events. The Company Option Agreement is described
more fully in Section 11 below.

     Parent and Purchaser have entered into Shareholder Agreements dated as of
July 12, 1999 (the "Shareholder Agreements"), with the directors of the Company
(the "Director Shareholders"), pursuant to which each of such Director
Shareholders has agreed, among other things, (1) to tender to Purchaser pursuant
to the Offer at $5.50 per share, all Shares beneficially owned by such Director
Shareholder (719,764 Shares in the aggregate) which will result in the Parent
and its affiliates beneficially owning 10.1% of the outstanding Shares, (2) to
grant to Parent an option exercisable under certain circumstances to purchase
the Shares beneficially owned by such Director Shareholder, and (3) to vote all
Shares beneficially owned by such Director Shareholder in favor of the Merger
Agreement and against all other acquisition proposals. See Section 11 below.

     The Merger Agreement provides that, upon the purchase by Purchaser of at
least a majority of the Shares pursuant to the Offer and from time to time
thereafter, Parent shall be entitled to designate such number of directors,
rounded up to the next whole number, on the Company Board of Directors so that
the percentage of Parent's nominees on the Company Board of Directors equals the
percentage of outstanding Shares beneficially owned by Parent and its
affiliates. The Company will, at such time, upon the request of Purchaser
promptly use its best efforts to take all action necessary to cause such persons
designated by Parent to be elected to the Company Board of Directors, if
necessary, by increasing the size of the Company Board of Directors or securing
resignations of its incumbent directors or both.

     Under Section 1924 of the PBCL, if a corporation owns at least 80% of the
outstanding shares of each class of another corporation, the corporation owning
such stock can effect a "short-form" merger with that corporation without any
action or vote on the part of the other shareholders of such other corporation
(a "short-form merger") if its board of directors adopts the merger. If the
Minimum Condition is satisfied and Purchaser purchases at least 80% of the
outstanding Shares, then under the PBCL, the Merger could be approved without
any action or vote on the part of Company's other shareholders. However, section
6 of the

                                        2
<PAGE>   5

Company's articles of incorporation provides that a merger or consolidation of
the Company with any person (or any affiliate of such person) that owns any
shares of any class of equity security of the Company requires the approval of a
majority of the voting securities of the Company not owned by such person and
its affiliates. The Company's articles of incorporation provides that section 6
thereof may be amended by the affirmative vote of 80% of the voting securities
of the Company entitled to vote thereon at a meeting called for that purpose. If
the Minimum Condition is satisfied and Purchaser purchases at least 80% of the
outstanding Shares, Purchaser will be able to effect the Articles Amendment and
delete section 6 from the Company's articles of incorporation without any action
or vote on the part of the other shareholders of the Company. Following the
approval of the Articles Amendment, Purchaser will be able to effect a
short-form merger without any further action or vote on the part of the other
shareholders of the Company. Parent presently intends to effect a short-form
merger if permitted to do so under the PBCL. The Merger Agreement is more fully
described in Section 11.

     Although under the terms of the Merger Agreement, Parent and Purchaser may
waive the Minimum Condition, they do not currently intend to do so and Parent
and Purchaser may terminate the Merger Agreement if the Minimum Condition is not
satisfied. In addition, the Merger Agreement provides that Purchaser may extend
the Offer if the Shares tendered and not withdrawn pursuant to the Offer are
less than 80% of the outstanding Shares. Even if Parent and Purchaser waive the
Minimum Condition and they do not own 80% of the outstanding Shares, following
consummation of the Offer, Parent and Purchaser could seek to purchase
additional shares in the open market or otherwise in order to reach the 80%
threshold required to approve the Articles Amendment and employ a short-form
merger under the PBCL. The per share consideration paid for any Shares so
acquired may be greater or less than that paid in the Offer. See Section 12.

     THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION AND SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS MADE
WITH RESPECT TO THE OFFER.

                                   THE OFFER

1. TERMS OF THE OFFER.

     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of such extension or
amendment), Purchaser will accept for payment and pay for all Shares validly
tendered prior to the Expiration Date, and not withdrawn in accordance with
Section 4. The term "Expiration Date" shall mean 12:00 Midnight, New York City
time, on Wednesday, August 11, 1999, unless and until Purchaser, in accordance
with the terms of the Merger Agreement, shall have extended the period of time
during which the Offer is open, in which event the term "Expiration Date" shall
mean the latest time and date at which the Offer, as so extended by Purchaser,
shall expire. In the Merger Agreement, Parent and Purchaser have agreed that if
all conditions to Purchaser's obligation to accept for payment and pay for
Shares pursuant to the Offer are not satisfied on the scheduled Expiration Date,
Purchaser may, in its sole discretion, extend the Offer.

     The Offer is conditioned upon the satisfaction of the Minimum Condition,
the expiration or termination of all waiting periods imposed by the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"), and the other conditions set forth in Section 14. If such conditions are
not satisfied prior to the Expiration Date, Purchaser reserves the right,
subject to the terms of the Merger Agreement and subject to complying with
applicable rules and regulations of the Commission, to (i) decline to purchase
any Shares tendered in the Offer and terminate the Offer and return all tendered
Shares to the tendering shareholders, (ii) waive any or all conditions to the
Offer and, to the extent permitted by applicable law, purchase all Shares
validly tendered, (iii) extend the Offer and, subject to the right of
shareholders to withdraw Shares until the Expiration Date, retain all Shares
which have been tendered during the period or periods for which the Offer is
extended or (iv) amend the Offer.

     The Merger Agreement requires Purchaser to accept for payment and pay for
all Shares validly tendered and not withdrawn pursuant to the Offer if all
conditions to the Offer are satisfied on the Expiration Date. However, if,
immediately prior to the scheduled Expiration Date, all conditions to the Offer
are not satisfied, Purchaser may, at its own discretion, extend the Offer.

     Any extension, amendment or termination of the Offer will be followed as
promptly as practicable by public announcement thereof, the announcement in the
case of an extension to be issued no later than 9:00 a.m., New York City time,
on the next business day after the previously scheduled Expiration Date in
accordance with Rules 14d-4(c), 14d-6(d) and 14e-1(d) under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"). As used in this Offer to
Purchase, "business day" has the meaning set forth in Rule 14d-1 under the
Exchange Act. Without limiting the obligation of Purchaser under such Rules or
the manner in which Purchaser may choose to make any public announcement,
Purchaser currently intends to make announcements by issuing a press release to
the Dow Jones News Service.

     If Purchaser extends the Offer, or if Purchaser (whether before or after
its acceptance for payment of Shares) is delayed in its purchase of, or payment
for, Shares or is unable to pay for Shares pursuant to the Offer for any reason,
then, without prejudice to Purchaser's rights under the Offer, the Depositary
may retain tendered Shares on behalf of Purchaser, and such Shares may not be
withdrawn except to the extent tendering shareholders are entitled to withdrawal
rights as described in Section 4. However, the ability of Purchaser to delay the
payment for Shares which Purchaser has accepted for payment is limited by Rule
14e-1(c) under the Exchange Act, which requires that a bidder pay the
consideration offered or return the securities deposited by, or on behalf of,
holders of securities promptly after the termination or withdrawal of the Offer.

     If Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer or waives a material condition of the Offer,
Purchaser will disseminate additional tender offer materials and extend the
Offer to the extent required by Rules 14d-4(c), 14d-6(d) and 14e-1 under the
Exchange Act. The minimum period during which the Offer must remain open
following material changes in the terms of the Offer or information concerning
the Offer, other than a change in price or a change in percentage of securities
sought, will depend upon the facts and circumstances then existing, including
the relative materiality of the changed terms or information. In a public
release, the Commission has stated its view that an offer must

                                        4
<PAGE>   7

remain open for a minimum period of time following a material change in the
terms of the Offer and that waiver of a material condition, such as the Minimum
Condition, is a material change in the terms of the Offer. The release states
that an offer should remain open for a minimum of five (5) business days from
the date a material change is first published, or sent or given to security
holders and that, if material changes are made with respect to information not
materially less significant than the offer price and the number of shares being
sought, a minimum of 10 business days may be required to allow adequate
dissemination and investor response. The requirement to extend the Offer will
not apply to the extent that the number of business days remaining between the
occurrence of the change and the then-scheduled Expiration Date equals or
exceeds the minimum extension period that would be required because of such
amendment. If, prior to the Expiration Date, Purchaser increases the
consideration offered to holders of Shares pursuant to the Offer, such increased
consideration will be paid to all holders whose Shares are purchased in the
Offer whether or not such Shares were tendered prior to such increase.

     The Company has provided Purchaser with the Company's shareholder lists and
security position listings for the purpose of disseminating the Offer to holders
of Shares. This Offer to Purchase and the related Letter of Transmittal will be
mailed to record holders of Shares and will be furnished to brokers, dealers,
banks and similar persons whose names, or the names of whose nominees, appear on
the shareholder lists or, if applicable, who are listed as participants in a
clearing agency's security position listing, for subsequent transmittal to
beneficial owners of Shares.

2. ACCEPTANCE FOR PAYMENT AND PAYMENT.

     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of any such extension
or amendment), Purchaser will accept for payment and will pay for, as soon as
practicable after the Expiration Date, all Shares validly tendered prior to the
Expiration Date and not properly withdrawn in accordance with Section 4.

     For purposes of the Offer, Purchaser will be deemed to have accepted for
payment, and thereby purchased, Shares properly tendered to Purchaser and not
withdrawn, if, as and when Purchaser gives oral or written notice to the
Depositary of Purchaser's acceptance for payment of such Shares. Payment for
Shares accepted for payment pursuant to the Offer will be made by deposit of the
purchase price therefor with the Depositary, which will act as agent for
tendering shareholders for the purpose of receiving payment from Purchaser and
transmitting payment to tendering shareholders. In all cases, payment for Shares
accepted for payment pursuant to the Offer will be made only after timely
receipt by the Depositary of (i) certificates for such Shares (or a timely Book
Entry Confirmation (as defined below) with respect thereto), (ii) a Letter of
Transmittal (or facsimile thereof), properly completed and duly executed, with
any required signature guarantees, or, in the case of a book-entry transfer, an
Agent's Message (as defined below) and (iii) any other documents required by the
Letter of Transmittal. Accordingly, payment may be made to tendering
shareholders at different times if delivery of the Shares and other required
documents occur at different times. The per share consideration paid to any
holder of Shares pursuant to the Offer will be the highest per share
consideration paid to any other holder of such Shares pursuant to the Offer.

UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID ON THE PURCHASE PRICE TO BE PAID BY
PURCHASER FOR THE SHARES, REGARDLESS OF ANY EXTENSION OF THE OFFER OR ANY DELAY
IN MAKING SUCH PAYMENT.

     The Purchaser expressly reserves the right, in its sole discretion, to
delay acceptance for payment of, or payment for, Shares in order to comply in
whole or in part with any applicable law. If Purchaser is delayed in its
acceptance for payment of, or payment for, Shares or is unable to accept for
payment or pay for Shares pursuant to the Offer for any reason, then, without
prejudice to Purchaser's rights under the Offer (including such rights as are
set forth in Sections 1 and 14) (but subject to compliance with Rule 14e-1(c)
under the Exchange Act), the Depositary may, nevertheless, on behalf of
Purchaser, retain tendered Shares, and such Shares may not be withdrawn except
to the extent tendering shareholders are entitled to exercise, and duly
exercise, withdrawal rights as described in Section 4.

                                        5
<PAGE>   8

     If any tendered Shares are not purchased pursuant to the Offer for any
reason, or if certificates are submitted representing more Shares than are
tendered, certificates evidencing Shares not tendered or not accepted for
purchase will be returned to the tendering shareholder, or such other person as
the tendering shareholder shall specify in the Letter of Transmittal, as
promptly as practicable following the expiration, termination or withdrawal of
the Offer. In the case of Shares delivered by book-entry transfer into the
Depositary's account at the Book-Entry Transfer Facility (as defined below)
pursuant to the procedures set forth in Section 3, such Shares will be credited
to such account maintained at the Book-Entry Transfer Facility as the tendering
shareholder shall specify in the Letter of Transmittal, as promptly as
practicable following the expiration, termination or withdrawal of the Offer. If
no such instructions are given with respect to Shares delivered by book-entry
transfer, any such Shares not tendered or not purchased will be returned by
crediting the account at the Book-Entry Transfer Facility designated in the
Letter of Transmittal as the account from which such Shares were delivered.

     Purchaser reserves the right to transfer or assign, in whole or, from time
to time, in part, to one or more of its affiliates, the right to purchase Shares
tendered pursuant to the Offer, but any such transfer or assignment will not
relieve Purchaser of its obligations under the Offer and will in no way
prejudice the rights of tendering shareholders to receive payment for Shares
validly tendered and accepted for payment pursuant to the Offer.

3. PROCEDURES FOR TENDERING SHARES.

     Valid Tender.  For Shares to be validly tendered pursuant to the Offer,
either (i) a properly completed and duly executed Letter of Transmittal (or
facsimile thereof), together with any required signature guarantees or, in the
case of a book-entry transfer, an Agent's Message, and any other required
documents, must be received by the Depositary at one of its addresses set forth
on the back cover of this Offer to Purchase prior to the Expiration Date and
either certificates evidencing tendered Shares must be received by the
Depositary at one of such addresses or such Shares must be delivered to the
Depositary pursuant to the procedures for book-entry transfer set forth below
and a Book-Entry Confirmation must be received by the Depositary, in each case
prior to the Expiration Date, or (ii) the tendering shareholder must comply with
the guaranteed delivery procedures described below.

     Book-Entry Transfer.  The Depositary will establish an account with respect
to the Shares at The Depository Trust Company (the "Book-Entry Transfer
Facility") for purposes of the Offer within two business days after the date of
this Offer to Purchase. Any financial institution that is a participant in the
Book-Entry Transfer Facility's system may make book-entry delivery of Shares by
causing the Book-Entry Transfer Facility to transfer such Shares into the
Depositary's account in accordance with such Book-Entry Transfer Facility's
procedures for such transfer. However, although delivery of Shares may be
effected through book-entry transfer into the Depositary's account at the
Book-Entry Transfer Facility, the Letter of Transmittal (or facsimile thereof),
properly completed and duly executed, with any required signature guarantees, or
an Agent's Message, and any other required documents must, in any case, be
transmitted to, and received by, the Depositary at one of its addresses set
forth on the back cover of this Offer to Purchase prior to the Expiration Date,
or the tendering shareholder must comply with the guaranteed delivery procedures
described below. The confirmation of a book-entry transfer of Shares into the
Depositary's account at the Book-Entry Transfer Facility as described above is
referred to herein as a "Book-Entry Confirmation."

DELIVERY OF THE LETTER OF TRANSMITTAL AND ANY OTHER REQUIRED DOCUMENTS TO THE
BOOK-ENTRY TRANSFER FACILITY WILL NOT CONSTITUTE DELIVERY TO THE DEPOSITARY.

     The term "Agent's Message" means a message transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that such Book-Entry Transfer Facility has
received an express acknowledgment from the participant in such Book-Entry
Transfer Facility tendering the Shares that such participant has received and
agrees to be bound by the terms of the Letter of Transmittal and that Purchaser
may enforce such agreement against such participant.

                                        6
<PAGE>   9

     THE METHOD OF DELIVERY OF SHARES, THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY TRANSFER FACILITY,
IS AT THE ELECTION AND RISK OF THE TENDERING SHAREHOLDER. SHARES WILL BE DEEMED
DELIVERED ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY (INCLUDING, IN THE CASE
OF A BOOK-ENTRY TRANSFER, BY BOOK-ENTRY CONFIRMATION). IF DELIVERY IS BY MAIL,
REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED.
IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

     Signature Guarantees.  No signature guarantee is required on the Letter of
Transmittal (i) if the Letter of Transmittal is signed by the registered
holder(s) (which term, for purposes of this Section, includes any participant in
the Book Entry Transfer Facility's systems whose name appears on a security
position listing as the owner of the Shares) of Shares tendered therewith and
such registered holder has not completed either the box entitled "Special
Delivery Instructions" or the box entitled "Special Payment Instructions" on the
Letter of Transmittal or (ii) if such Shares are tendered for the account of a
financial institution (including most commercial banks, savings and loan
associations and brokerage houses) that is a participant in the Security
Transfer Agents Medallion Program, the New York Stock Exchange Medallion
Signature Guarantee Program or the Stock Exchange Medallion Program (each, an
"Eligible Institution" and, collectively, "Eligible Institutions"). In all other
cases, all signatures on Letters of Transmittal must be guaranteed by an
Eligible Institution. See Instructions 1 and 5 to the Letter of Transmittal. If
the certificates for Shares are registered in the name of a person other than
the signer of the Letter of Transmittal, or if payment is to be made, or
certificates for Shares not tendered or not accepted for payment are to be
returned, to a person other than the registered holder of the certificates
surrendered, then the tendered certificates for such Shares must be endorsed or
accompanied by appropriate stock powers, in either case, signed exactly as the
name or names of the registered holders or owners appear on the certificates,
with the signatures on the certificates or stock powers guaranteed as aforesaid.
See Instruction 5 to the Letter of Transmittal.

     Guaranteed Delivery.  If a shareholder desires to tender Shares pursuant to
the Offer and such shareholder's certificates for Shares are not immediately
available or the procedures for book-entry transfer cannot be completed on a
timely basis or time will not permit all required documents to reach the
Depositary prior to the Expiration Date, such shareholder's tender may be
effected if all the following conditions are met:

          (i) such tender is made by or through an Eligible Institution;

          (ii) a properly completed and duly executed Notice of Guaranteed
     Delivery, substantially in the form provided by Purchaser, is received by
     the Depositary, as provided below, prior to the Expiration Date; and

          (iii) the certificates for (or a Book-Entry Confirmation with respect
     to) such Shares, together with a properly completed and duly executed
     Letter of Transmittal (or facsimile thereof), with any required signature
     guarantees, or, in the case of a book-entry transfer, an Agent's Message,
     and any other required documents, are received by the Depositary within
     three trading days after the date of execution of such Notice of Guaranteed
     Delivery. A "trading day" is any day on which the Nasdaq National Market
     (the "Nasdaq National Market"), operated by the National Association of
     Securities Dealers, Inc. (the "NASD"), is open for business.

     The Notice of Guaranteed Delivery may be delivered by hand to the
Depositary, transmitted by telegram or mailed to the Depositary and must include
a guarantee by an Eligible Institution in the form set forth in such Notice of
Guaranteed Delivery.

     The valid tender of Shares pursuant to one of the procedures described
above will constitute a binding agreement between the tendering shareholder and
Purchaser upon the terms and subject to the conditions of the Offer.

     Appointment.  By executing the Letter of Transmittal as set forth above
(including delivery through an Agent's Message), the tendering shareholder will
irrevocably appoint designees of Purchaser as such shareholder's
attorneys-in-fact and proxies in the manner set forth in the Letter of
Transmittal, each with full

                                        7
<PAGE>   10

power of substitution, to the full extent of such shareholder's rights with
respect to the Shares tendered by such shareholder and accepted for payment by
Purchaser and with respect to any and all non-cash dividends, distributions,
rights, other Shares or other securities issued or issuable in respect of such
Shares on or after July 12, 1999 (collectively, "Distributions"). All such
proxies will be considered coupled with an interest in the tendered Shares. Such
appointment will be effective if, as and when, and only to the extent that,
Purchaser accepts for payment Shares tendered by such shareholder as provided
herein. All such powers of attorney and proxies will be irrevocable and will be
deemed granted in consideration of the acceptance for payment by Purchaser of
Shares tendered in accordance with the terms of the Offer. Upon such
appointment, all prior powers of attorney, proxies and consents given by such
shareholder with respect to such Shares (and any and all Distributions) will,
without further action, be revoked and no subsequent powers of attorney,
proxies, consents or revocations may be given by such shareholder (and, if
given, will not be deemed effective). The designees of Parent will thereby be
empowered to exercise all voting and other rights with respect to such Shares
(and any and all Distributions), including, without limitation, in respect of
any annual or special meeting of the Company's shareholders (and any adjournment
or postponement thereof), actions by written consent in lieu of any such meeting
or otherwise, as each such attorney-in-fact and proxy or his substitute shall in
his sole discretion deem proper. Purchaser reserves the right to require that,
in order for Shares to be deemed validly tendered, immediately upon Purchaser's
acceptance for payment of such Shares, Purchaser must be able to exercise full
voting, consent and other rights with respect to such Shares (and any and all
Distributions), including voting at any meeting of shareholders.

     Determination of Validity.  All questions as to the validity, form,
eligibility (including time of receipt) and acceptance for payment of any tender
of Shares will be determined by Purchaser, in its sole discretion, which
determination will be final and binding. Purchaser reserves the absolute right
to reject any or all tenders of any Shares determined by it not to be in proper
form or the acceptance for payment of which, or payment for which, may, in the
opinion of Purchaser's counsel, be unlawful. Purchaser also reserves the
absolute right, in its sole discretion, subject to the provisions of the Merger
Agreement, to waive any defect or irregularity in any tender of Shares of any
particular shareholder, whether or not similar defects or irregularities are
waived in the case of other shareholders. No tender of Shares will be deemed to
have been validly made until all defects or irregularities relating thereto have
been cured or waived. None of Purchaser, Parent, the Dealer Manager, the
Depositary, the Information Agent or any other person will be under any duty to
give notification of any defects or irregularities in tenders or incur any
liability for failure to give any such notification. Subject to the terms of the
Merger Agreement, Purchaser's interpretation of the terms and conditions of the
Offer in this regard (including the Letter of Transmittal and the instructions
thereto) will be final and binding.

     Backup Withholding.  Under the "backup withholding" provisions of federal
income tax law, unless a tendering registered holder, or its assignee (in either
case, the "Payee"), satisfies the conditions described in Instruction 10 of the
Letter of Transmittal or is otherwise exempt, the cash payable as a result of
the Offer may be subject to backup withholding tax at a rate of 31% of the gross
proceeds. To prevent backup withholding, each Payee should complete and sign the
Substitute Form W-9 provided in the Letter of Transmittal. See Instruction 10 to
the Letter of Transmittal.

4. WITHDRAWAL RIGHTS.

     Except as otherwise provided in this Section 4 or as provided by applicable
law, tenders of Shares are irrevocable. Shares tendered pursuant to the Offer
may be withdrawn pursuant to the procedures set forth below at any time prior to
the Expiration Date and, unless theretofore accepted for payment and paid for by
Purchaser pursuant to the Offer, may also be withdrawn at any time after
September 12, 1999.

     To be effective, a written or telegraphic notice of withdrawal must be
timely received by the Depositary at one of its addresses set forth on the back
cover of this Offer to Purchase. Any such notice of withdrawal must specify the
name of the person who tendered the Shares to be withdrawn, the number of Shares
to be withdrawn and the name of the registered holder of the Shares to be
withdrawn, if different from the name of the person who tendered the Shares. If
certificates evidencing Shares to be withdrawn have been delivered or otherwise
identified to the Depositary, then, prior to the physical release of such
certificates, the serial numbers shown on such certificates must be submitted to
the Depositary and, unless such Shares have been
                                        8
<PAGE>   11

tendered by an Eligible Institution, the signatures on the notice of withdrawal
must be guaranteed by an Eligible Institution. If Shares have been delivered
pursuant to the procedures for book-entry transfer as set forth in Section 3,
any notice of withdrawal must also specify the name and number of the account at
the Book-Entry Transfer Facility to be credited with the withdrawn Shares and
otherwise comply with such Book-Entry Transfer Facility's procedures.

     Withdrawals of tendered Shares may not be rescinded, and any Shares
withdrawn will thereafter be deemed not validly tendered for purposes of the
Offer. However, withdrawn Shares may be retendered by again following one of the
procedures described in Section 3 at any time prior to the Expiration Date.

     All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by Purchaser, in its sole discretion,
which determination will be final and binding. None of Purchaser, Parent, the
Depositary, the Information Agent or any other person will be under any duty to
give notification of any defects or irregularities in any notice of withdrawal
or incur any liability for failure to give any such notification.

5. CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES.

     The following is a general summary of certain U.S. federal income tax
consequences of the Offer and the Merger relevant to a beneficial holder of
Shares whose Shares are tendered and accepted for payment pursuant to the Offer
or whose Shares are converted to cash in the Merger (a "Holder"). The discussion
is based on the Internal Revenue Code of 1986, as amended (the "Code"),
regulations issued thereunder, judicial decisions and administrative rulings,
all of which are subject to change, possibly with retroactive effect. The
following does not address the U.S. federal income tax consequences to all
categories of Holders that may be subject to special rules (e.g., holders who
acquired their Shares pursuant to the exercise of employee stock options or
other compensation arrangements with the Company, holders who perfect their
appraisal rights under the PBCL, foreign holders, insurance companies,
tax-exempt organizations, dealers in securities and persons who have acquired
the Shares as part of a straddle, hedge, conversion transaction or other
integrated investment), nor does it address the federal income tax consequences
to persons who do not hold the Shares as "capital assets" within the meaning of
Section 1221 of the Code (generally, property held for investment). Holders
should consult their own tax advisors regarding the U.S. federal, state, local
and foreign income and other tax consequences of the Offer and the Merger.

     The receipt of cash for Shares pursuant to the Offer or the Merger will be
a taxable transaction for U.S. federal income tax purposes and may also be a
taxable transaction under applicable state, local and foreign income and other
tax laws. In general, a Holder who sells Shares pursuant to the Offer or
receives cash in exchange for Shares pursuant to the Merger will recognize gain
or loss for federal income tax purposes equal to the difference, if any, between
the amount of cash received and the Holder's adjusted tax basis in the Shares
sold pursuant to the Offer or surrendered for cash pursuant to the Merger. Gain
or loss will be determined separately for each block of Shares (i.e., Shares
acquired at the same cost in a single transaction) tendered pursuant to the
Offer or surrendered for cash pursuant to the Merger. Such gain or loss will be
long-term capital gain or loss if the Holder has held the Shares for more than
one (1) year at the time of the consummation of the Offer or the Merger. Capital
gains recognized by an individual investor (or an estate or certain trusts) upon
a disposition of a Share that has been held for more than one year generally
will be subject to a maximum tax rate of 20% or, in the case of a Share that has
been held for one year or less, will be subject to tax at ordinary income rates.
Certain limitations apply to the use of capital losses.

  Third Quarter through July 14, 1999.......................   5.38     4.50
</TABLE>

     On July 12, 1999, the last full trading day prior to the public
announcement of the execution of the Merger Agreement, the last reported closing
sales price of the Shares on the Nasdaq National Market was $4.81 per Share. On
July 14, 1999, the last full trading day prior to the commencement of the Offer,
the last reported sales price of the Shares on the Nasdaq National Market was
$5.31 per Share. Shareholders are urged to obtain a current market quotation for
the Shares.

     The Company issued a $0.02 cash dividend each quarter from February 1997
through May 1998. In addition, under the terms of the Merger Agreement, the
Company is not permitted to declare or pay dividends with respect to the Shares
without the prior written consent of Parent; Parent does not intend to consent
to any such declaration or payment.

7. EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES; STOCK LISTING; EXCHANGE ACT
   REGISTRATION; MARGIN REGULATIONS.

     Market for the Shares.  The purchase of Shares by Purchaser pursuant to the
Offer will reduce the number of Shares that might otherwise trade publicly and
will reduce the number of holders of Shares, which, depending upon the number of
Shares so purchased, could adversely affect the liquidity and market value of
the remaining Shares held by shareholders. Purchaser cannot predict whether the
reduction in the number of Shares that might otherwise trade publicly would have
an adverse or beneficial effect on the market price for, or marketability of,
the Shares or whether it would cause future market prices to be greater or less
than the Offer Price.

     Nasdaq Quotation.  Depending upon the number of Shares purchased pursuant
to the Offer, the Shares may no longer meet the requirements of the NASD for
continued inclusion on the Nasdaq National Market, which requires that an issuer
have at least 500,000 publicly held shares, held by at least 300 round lot
shareholders, with a market value of at least $1,000,000, have at least two
market makers, have a minimum bid price of $1 and have either (A) net tangible
assets of at least $2,000,000; (B) a market capitalization of at least
$35,000,000; or (C) net income of $500,000 in the most recently completed fiscal
year or in two of the last three most recently completed fiscal years. If the
Nasdaq National Market was to cease to publish quotations for the Shares, it is
possible that the Shares would continue to trade in the over-the-counter market
and that price or other quotations would be reported by other sources. The
extent of the public market for such Shares and the availability of such
quotations would depend, however, upon such factors as the number of

                                       10
<PAGE>   13

shareholders and/or the aggregate market value of such securities remaining at
such time, the interest in maintaining a market in the Shares on the part of
securities firms, the possible termination of registration under the Exchange
Act as described below, and other factors. Purchaser cannot predict whether the
reduction in the number of Shares that might otherwise trade publicly would have
an adverse or beneficial effect on the market price for, or marketability of,
the Shares or whether it would cause future market prices to be greater or
lesser than the Offer Price.

     Exchange Act Registration.  The Shares are currently registered under the
Exchange Act. Registration of the Shares under the Exchange Act may be
terminated upon application of the Company to the Commission if the Shares are
neither listed on a national securities exchange nor held by 300 or more holders
of record. Termination of registration of the Shares under the Exchange Act
would substantially reduce the information required to be furnished by the
Company to its shareholders and to the Commission and would make certain
provisions of the Exchange Act no longer applicable to the Company, such as the
short-swing profit recovery provisions of Section 16(b), the requirement of
furnishing a proxy statement pursuant to Section 14(a) in connection with
shareholders' meetings and the related requirement of furnishing an annual
report to shareholders and the requirements of Rule 13e-3 under the Exchange Act
with respect to "going private" transactions. Furthermore, the ability of
"affiliates" of the Company and persons holding "restricted securities" of the
Company to dispose of such securities pursuant to Rule 144 or Rule 144A
promulgated under the Securities Act of 1933, as amended (the "Securities Act"),
may be impaired or eliminated.

     Margin Regulations.  The Shares are presently "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System (the
"Federal Reserve Board"), which status has the effect, among other things, of
allowing brokers to extend credit on the collateral of the Shares. Depending
upon factors similar to those described above regarding stock exchange listing
and market quotations, it is possible that, following the Offer, the Shares
would no longer constitute "margin securities" for the purposes of the margin
regulations of the Federal Reserve Board and therefore could no longer be used
as collateral for loans made by brokers. In addition, if registration of the
Shares under the Exchange Act were terminated, the Shares would no longer
constitute "margin securities."

     Parent currently intends to seek delisting of the Shares from the Nasdaq
National Market and the termination of the registration of the Shares under the
Exchange Act as soon after the completion of the Offer as the requirements for
such delisting and termination are met. If the Nasdaq National Market listing
and the Exchange Act registration of the Shares are not terminated prior to the
Merger, then the Shares will be delisted from the Nasdaq National Market and the
registration of the Shares under the Exchange Act will be terminated following
the consummation of the Merger.

included financial projections for the Company as an independent company (i.e.,
without regard to the impact to the Company of a transaction with Parent), which
information is summarized as set forth below:

     The foregoing information was prepared by the Company solely for internal
use and not for publication or with a view to complying with the published
guidelines of the Commission regarding projections or with the guidelines
established by the American Institute of Certified Public Accountants and are
included in this Offer to Purchase only because they were furnished to Parent.
The foregoing information is "forward-looking" and inherently subject to
significant uncertainties and contingencies, many of which are beyond the
control of the Company, including industry performance, general business and
economic conditions, changing competition, adverse changes in applicable laws,
regulations or rules governing environmental, tax or accounting matters and
other matters. Although the Company has informed Parent and Purchaser that it
believes the assumptions used in preparing this information were reasonable when
made, such assumptions are inherently subject to significant uncertainties and
contingencies which are impossible to predict and beyond the

                                       12
<PAGE>   15

Company's control. One cannot predict whether the assumptions made in preparing
the foregoing information will be accurate, and accordingly, there can be no
assurance, and no representation or warranty is made, that actual results will
not vary materially from those described above. The inclusion of this
information should not be regarded as an indication that Parent, Purchaser, the
Company or anyone who received this information considered it a reliable
prediction of future events, and this information should not be relied on as
such. None of Parent, Purchaser, the Dealer Manager, or the Company assumes any
responsibility for the validity, reasonableness, accuracy or completeness of the
projections, and the Company has made no representation to Parent or Purchaser
regarding the financial information described above. The projections have not
been adjusted to reflect the effects of the Merger.

     Available Information.  The Company is subject to the informational filing
requirements of the Exchange Act and, in accordance therewith, is obligated to
file reports, proxy statements and other information with the Commission
relating to its business, financial condition and other matters. Information as
of particular dates concerning the Company's directors and officers, their
remuneration, options granted to them, the principal holders of the Company's
securities and any material interests of such persons in transactions with the
Company is required to be disclosed in proxy statements distributed to the
Company's shareholders and filed with the Commission. Such reports, proxy
statements and other information should be available for inspection at the
public reference facilities of the Commission at 450 Fifth Street, N.W.,
Washington, D.C. 20549, and at the regional offices of the Commission located at
Seven World Trade Center, Suite 1300, New York, NY 10048 and Citicorp Center,

11. BACKGROUND OF THE OFFER; PURPOSE OF THE OFFER AND THE MERGER; THE MERGER
    AGREEMENT AND CERTAIN OTHER AGREEMENTS.

  Contacts with the Company; Background of the Offer.

     One of Parent's strategic objectives has been the acquisition of domestic
non-room air conditioner businesses that are counter-seasonal or non-seasonal to
the room air conditioner business.

     On August 14, 1998, the Company entered into a merger agreement with McLeod
Russel Holdings PLC ("McLeod Russel") providing for the acquisition of all of
the outstanding stock of the Company at a price of $7.27 per share. On October
15, 1998, the Company and McLeod Russel announced that they had mutually
terminated the merger agreement. On November 4, 1998, the Company announced that
the Company Board of Directors had determined not to pursue a sale of the
Company pending year-end results but that the

                                       14
<PAGE>   17

Company Board of Directors would consider unsolicited expressions of interest it
might receive from third parties.

     On November 10, 1998, Sal Giordano, Jr., Vice Chairman and Chief Executive
Officer of Parent, sent a letter to Steven L. Schneider, President and Chief
Executive Officer of the Company, indicating Parent's possible interest in
acquiring the Company. The Company's financial advisor, Harris Williams
communicated to Parent that the Company was reviewing its alternatives and would
respond in due course.

     On February 3, 1999, the Company announced its results for the 1998 fiscal
year. Also on that day, Mr. Giordano, Jr. sent another letter to Mr. Schneider
and the Company Board of Directors, reiterating Parent's interest in acquiring
the Company. On February 25, 1999, Parent and the Company signed the
Confidentiality Agreement (as hereinafter defined) and on March 4, 1999, Parent
retained TM Capital as its financial advisor in connection with the proposed
acquisition of the Company.

     On March 17, 1999, the Company Board of Directors announced it had decided
to pursue strategic alternatives, including the possible sale of the Company.
The Company also announced that it had retained Harris Williams as its financial
advisor.

     On March 29, 1999, Harris Williams provided Parent with a descriptive
memorandum regarding the Company and requested expressions of interest by April
13, 1999. On April 13, 1999, Parent provided a preliminary expression of
interest in acquiring the Company for a cash price in the range of $5.50 per
share.

     On May 5, 1999, Mr. Giordano, Jr. and Mr. Robert L. Laurent, Jr., Executive
Vice President, Acquisitions and Alliances of Parent and representatives of TM
Capital met with Mr. Schneider, Mr. Calvin Monsma and other members of
management of the Company and representatives of Harris Williams at the
Company's Sanford, North Carolina facility. The parties discussed the Company's
business, Parent's and the Company's common strategies and various synergistic
opportunities between the two companies.

     On May 12, 1999, Harris Williams requested that Parent submit a proposal
for the acquisition of the Company by June 2, 1999.

     On May 19, 1999, members of Parent's management and the Company's
management visited the Company's Envirco subsidiary in Albuquerque, New Mexico.
On May 24 and May 25, 1999, members of Parent's senior management and
representatives of TM Capital conducted a due diligence review of certain
information regarding the Company in a data room at the offices of the Company's
counsel in Raleigh, North Carolina. From May 24, 1999 through July 8, 1999,
members of Parent's management and its representatives continued to conduct a
due diligence review of information regarding the Company.

     In a letter dated June 2, 1999 from Mr. Robert L. Laurent, Jr. of Parent to
the Company, Parent indicated to the Company that it was prepared to consider
the acquisition of 100% of the common stock of the Company at a price of $5.50
in cash per share, subject to the satisfactory completion of Parent's due
diligence and the negotiation of definitive documentation. On June 8, 1999,
Harris Williams contacted Parent and TM Capital to request an increase in the
price proposed by Parent. On June 9, 1999, Parent indicated to Harris Williams
that it might be prepared to offer $5.65 per share, subject to the satisfactory
completion of its due diligence and the negotiation of definitive documentation.

     On June 11, 1999, Mr. Giordano, Jr. met with Mr. Schneider for further
discussions about a potential transaction.

     From June 9 through July 8, 1999, members of senior management of Parent,
its financial and legal advisors and senior members of the Company's management
and its financial and legal advisors conducted negotiations regarding the terms
of a proposed tender offer and merger and members of Parent's management and its
representatives conducted further due diligence.

     On July 8, 1999, after completion of Parent's due diligence, TM Capital
notified Harris Williams orally and on July 9, 1999 Mr. Giordano, Jr. delivered
a letter to the Company Board of Directors, in each case communicating Parent's
offer to purchase all of the outstanding shares of common stock of the Company
at a

                                       15
<PAGE>   18

purchase price of $5.50 in cash upon the terms and conditions set forth in the
Merger Agreement previously negotiated by the parties and their respective
counsel. Also on July 9, 1999, representatives of Parent and representatives of
the Company discussed via telephone the results of Parent's due diligence
investigation and Parent's rationale for its proposed $5.50 per share price.

     On July 12, 1999, Harris Williams called TM Capital to inform Parent that
the Company Board of Directors (by a unanimous vote of those directors present)
accepted Parent's proposal, authorized the execution of the Merger Agreement and
the Company Option Agreement and agreed to recommend that the Company's
shareholders accept the Offer and tender their shares pursuant thereto. The
Merger Agreement, the Company Option Agreement and the Shareholder Agreements
were all executed on July 12, 1999 and Parent and the Company issued a joint
press release announcing the Offer and the execution of the Merger Agreement.

     On July 15, 1999, pursuant to the terms of the Merger Agreement, Parent and
Purchaser commenced the Offer.

     Purpose of the Offer and the Merger.  The purpose of the Offer and the
Merger is to enable Parent to acquire control of, and the entire equity interest
in, the Company. Upon consummation of the Merger, the Company will become an
indirect wholly owned subsidiary of Parent. The Offer is being made pursuant to
the Merger Agreement and is intended to increase the likelihood that the Merger
will be effected. The purpose of the Merger is to acquire all of the outstanding
Shares not purchased pursuant to the Offer.

  Merger Agreement

     The following is a summary of certain provisions of the Merger Agreement.
This summary is not a complete description of the terms and conditions of the
Merger Agreement and is qualified in its entirety by reference to the full text
of the Merger Agreement, which is incorporated herein by reference and a copy of
which has been filed with the Commission as an exhibit to the Schedule 14D-1.
The Merger Agreement may be examined, and copies obtained, as set forth in
Sections 8 and 9 of this Offer to Purchase.

     The Offer.  The Merger Agreement provides for the making of the Offer as
provided in this Offer to Purchase.

     The Company Board of Directors.  The Merger Agreement provides that Parent
shall be entitled to designate a number of directors, rounded up to the next
whole number, of the Company Board of Directors equal to the product of the
total number of directors on the Company Board of Directors (giving effect to
the directors designated by Parent) multiplied by a fraction of which the
numerator shall be the number of Shares which Parent and its subsidiaries
(including Purchaser) beneficially own at that time, and the denominator shall
be the total number of Shares then outstanding. The Directors so designated by
Parent shall take office immediately after (i) the purchase of and payment for
any Shares by Parent or any of its subsidiaries as a result of which Parent and
its subsidiaries owns beneficially at least a majority of then outstanding
Shares and (ii) compliance with Section 14(f) of the Exchange Act and Rule 14f-1
promulgated thereunder, whichever shall occur later. In furtherance thereof, the
Company shall, upon request of Parent, use its best efforts promptly either to
increase the size of the Company Board of Directors or to secure the
resignations of such number of its incumbent directors, or both, as is necessary
to enable such designees of Parent to be so elected or appointed to the Company
Board of Directors, and the Company shall take all actions available to the
Company to cause such designees of Parent to be so elected or appointed. At such
time, the Company shall, if requested by Parent, also take all action necessary
to cause persons designated by Parent to constitute the same percentage (rounded
up to the next whole number) as is on the Company Board of Directors of (i) each
committee of the Company Board of Directors, (ii) each board of directors (or
similar body) of each of the Company's subsidiaries and (iii) each committee (or
similar body) of each such board.

     The Merger Agreement provides that the Company will promptly take, at its
expense, all actions required pursuant to Section 14(f) of the Exchange Act and
Rule 14f-1 promulgated thereunder in order to fulfill its obligations under the
prior paragraph, including mailing to shareholders the information required by
such Section 14(f) and Rule 14f-1 as is necessary to enable Parent's designees
to be elected or appointed to the

                                       16
<PAGE>   19

Company Board of Directors immediately after the purchase of and payment for any
Shares by Parent or any of its subsidiaries as a result of which Parent and its
subsidiaries own beneficially at least a majority of then outstanding Shares.
Parent or Purchaser will supply the Company all information with respect to
either of them and their nominees, officers, directors and affiliates required
to be disclosed by Section 14(f) and Rule 14f-1. The provisions of the Merger
Agreement related to these Commission filings are in addition to and shall not
limit any rights which Purchaser, Parent or any of their Affiliates may have as
a holder or beneficial owner of Shares as a matter of law with respect to the
election of directors or otherwise. The term "Affiliate" has the meaning as set
forth in Rule 12b-2 of the Exchange Act.

     The Merger Agreement provides that in the event that Parent's designees are
elected or appointed to the Company Board of Directors, until the Effective
Time, the Company Board of Directors shall have at least two directors who were
directors as of the date of the Merger Agreement and who are not employees of
the Company ("Independent Directors"), provided that, in such event, if the
number of Independent Directors shall be reduced below two for any reason
whatsoever, the remaining Independent Director shall be entitled to designate
persons to fill such vacancies who shall be deemed to be Independent Directors
or, if no Independent Director then remains, the other directors shall designate
two persons to fill such vacancies who shall not be shareholders, affiliates or
associates of Parent or Purchaser, and such persons shall be deemed to be
Independent Directors. In the event that Parent's designees constitute a
majority of the directors on the Company Board of Directors, the affirmative
vote of a majority of the Independent Directors shall be required after the
acceptance for payment of Shares pursuant to the Offer and prior to the
Effective Time, to (a) amend or terminate the Merger Agreement by the Company,
(b) exercise or waive any of the Company's rights, benefits or remedies
hereunder if such exercise or waiver materially and adversely affects holders of
Shares other than Parent or Purchaser, or (c) take any other action under or in
connection with the Merger Agreement if such action materially and adversely
affects holders of Shares other than Parent or Purchaser; provided, that if
there shall be no such directors, such actions may be effected by unanimous vote
of the entire Company Board of Directors.

     The Merger.  The Merger Agreement provides that, upon the terms and subject
to the conditions thereof and in accordance with the PBCL, Purchaser will be
merged with and into the Company and the separate corporate existence of
Purchaser will thereupon cease, and the Company will be the surviving
corporation in the Merger. At the Effective Time of the Merger, each Share then
outstanding, other than Shares held by (i) the Company, (ii) Parent or any of
its wholly owned subsidiaries including Purchaser, and (iii) shareholders who
properly perfect their dissenters' rights under the PBCL, will be converted into
the right to receive $5.50 in cash or any higher price per Share paid in the
Offer, without interest.

     Options.  The Merger Agreement provides that immediately prior to the
Effective Time, each holder of a Company Option will be entitled to receive from
the Company, and shall receive, except as discussed below, in settlement of each
Company Option an option to purchase shares of Parent's Class A Stock (a "Parent
Option"). All Company Options shall terminate as of the Effective Time. Parent
shall grant, as of the Effective Time, to the holder of any Company Option, a
Parent Option. With respect to such Parent Options (i) the number of shares of
Parent Class A Stock subject to such Parent Option will be determined by
multiplying the number of shares constituting the Company Option by the Option
Exchange Ratio (as defined below), rounding any fractional share up to the
nearest whole share, and (ii) the exercise price per share of such Parent Option
will be determined by dividing the exercise price per share applicable to the
Company Option by the Option Exchange Ratio, and rounding the exercise price
thus determined up to the nearest whole cent. Except as provided above, the
converted or substituted Parent Options shall be subject to the same terms and
conditions (including, without limitation, expiration date, vesting and exercise
provisions) as were applicable to the Company Options immediately prior to the
Effective Time; provided, however, that (i) all Company Options shall vest and
become fully exercisable immediately prior to the Effective Time and (ii) any
Company Option that qualifies as an incentive stock option (an "ISO") under
Section 422 of the Code, shall, to the extent permitted by applicable law, be
adjusted so that the resulting Parent Option qualifies as an ISO. The term
"Option Exchange Ratio" means (x) the Offer Price divided by (y) the average of
the closing prices of Parent Class A Stock on the New York Stock Exchange during
the ten trading days preceding the fifth trading day prior to the date of the
closing of Merger (the "Closing Date"). Each holder of

                                       17
<PAGE>   20

a Company Option that does not qualify as an ISO shall also have the right
(which right shall be exercised at least 5 days prior to the Closing Date by
written notice to Company) to elect, in lieu of the right to acquire a Parent
Option, to convert, at the Effective Time, all or a portion of his or her
Company Options which have not been exercised and which have not expired prior
to the Effective Time into the right to receive an amount equal to the product
of (i) the excess, if any, of the Offer Price (excluding any interest,
regardless of when paid) over the exercise price per Share of such Company
Option and (ii) the number of shares constituting such Company Option less any
applicable withholding taxes.

     The Merger Agreement provides that, except as may be otherwise agreed to by
Parent and the Company, all stock option plans established by the Company or any
of its subsidiaries shall terminate as of the Effective Time and the provisions
in any other plan, program or arrangement providing for the issuance or grant of
any other interest in respect of the capital stock of Company or any its
subsidiaries shall be deleted, terminated and of no further force or effect as
of the Effective Time. If and to the extent necessary or required by the terms
of the plans governing Company Options or pursuant to the terms of any Company
Option granted thereunder, prior to the Effective Time, the Company shall (i)
obtain the consent of each holder of outstanding Company Options and (ii) amend
the terms of the applicable plan under which the Company Option was granted, in
each case as is necessary to give effect to the foregoing treatment of such
Company Options.

     Representations and Warranties.  In the Merger Agreement, the Company has
made customary representations and warranties to Parent and Purchaser with
respect to, among other things, corporate organization, good standing, authority
to enter into the Merger Agreement and the Company Option Agreement, shareholder

the Merger Agreement and prior to the Effective Time and except as expressly
contemplated by the Merger Agreement or in a schedule thereto or as agreed to in

          (f) neither the Company nor any of its subsidiaries will (i) change

     the Effective Time, or that would materially impair the ability of the

     materially delay such consummation; and

          (h) neither the Company nor any of its subsidiaries will enter into an
     agreement, contract, commitment or arrangement to do any of the foregoing,
     or to authorize, recommend, propose or announce an intention to do any of

     Shareholders' Meetings.  Following the acceptance for payment and purchase
of Shares by Purchaser pursuant to the Offer, the Company shall take all action
necessary in accordance with the PBCL, the Company's articles of incorporation
and by-laws (the "By-laws") and the Exchange Act to effect the Articles
Amendment. The Articles Amendment requires the approval of at least 80% of the
voting securities of the Company entitled to vote thereon at a meeting called
for that purpose. If the Minimum Condition is satisfied and Purchaser purchases
at least 80% of the outstanding Shares, Purchaser will be able to effect the
Articles Amendment and delete section 6 from the Company's articles of
incorporation without any action or vote on the part of the other shareholders
of the Company. The Merger Agreement provides that in order to effect the
Articles Amendment, the Company will, in accordance with applicable law, (i)
duly call, give notice of, convene and hold a special meeting of its
shareholders as promptly as practicable following the acceptance for payment and
purchase of Shares by the Purchaser pursuant to the Offer for the purpose of
considering and taking action upon the approval of the Articles Amendment; (ii)
if required, prepare and file with the Commission a preliminary proxy or
information statement relating to the Articles Amendment and use its best
efforts to obtain and furnish the information required to be included by the
Commission in such proxy

                                       19
<PAGE>   22

statement and, after consultation with Parent, respond promptly to any comments
made by the Commission with respect to such proxy statement and cause a
definitive proxy or information statement, including any amendment or supplement
thereto to be mailed to the Company's shareholders; (iii) include in the proxy
statement the recommendation of the Company Board of Directors that shareholders
of the Company vote in favor of the approval of the Articles Amendment; and (iv)
use its best efforts to solicit proxies in favor of the Articles Amendment from
holders of Shares and take all other action necessary or, in the reasonable
opinion of Parent, advisable to secure any vote or consent of shareholders
required by the PBCL, the Company's articles of incorporation and the By-laws to
effect the Articles Amendment. Following approval of the Articles Amendment and
if the Minimum Condition has been satisfied and Purchaser purchases at least 80%
of the outstanding Shares, then at the election of the Purchaser, a short-form
merger could be effected without any action or vote on the part of the other
shareholders of the Company.

     In the event that Purchaser does not acquire 80% of the outstanding Shares,
then a shareholder vote will be required to approve the Merger. Pursuant to the
Merger Agreement, if required by applicable law in order to consummate the
Merger, the Company will (i) duly call, give notice of, convene and hold a
special meeting of its shareholders as promptly as practicable following the
acceptance for payment and purchase of Shares by Purchaser pursuant to the Offer
for the purpose of considering and taking action upon the approval of the Merger
and the adoption of the Merger Agreement; (ii) prepare and file with the
Commission a preliminary proxy or information statement relating to the Merger
and the Merger Agreement and use its best efforts to obtain and furnish the
information required to be included by the Commission in the proxy statement
and, after consultation with Parent, to respond promptly to any comments made by
the Commission with respect to the preliminary proxy or information statement
and cause a definitive proxy or information statement, including any amendment
or supplement thereto to be mailed to its shareholders, provided that no
amendment or supplement to such proxy or information statement will be made by
the Company without consultation with Parent and its counsel; (iii) include in
the proxy statement the recommendation of the Company Board of Directors that
shareholders of the Company vote in favor of the approval of the Merger and the
adoption of the Merger Agreement; and (iv) use its best efforts to solicit from
holders of Shares proxies in favor of the Merger and take all other action
necessary or, in the reasonable opinion of Parent, advisable to secure any vote
or consent of shareholders required by the PBCL, the Company's articles of
incorporation and the By-laws to effect the Merger.

     No Solicitation.  Pursuant to the Merger Agreement, the Company has agreed
that it will not (and the Company will cause the representatives of the Company,
each of its subsidiaries and each affiliate of the Company, not to), directly or
indirectly, encourage, solicit, participate in or initiate discussions or
negotiations with, or provide any information to, any Person or group (other
than Parent, any of its affiliates or representatives) concerning any proposal
or offer to acquire all or a substantial part of the business or properties of
the Company or any of its subsidiaries or any capital stock of the Company or
any of its subsidiaries, whether by merger, tender offer, exchange offer, sale
of assets or similar transactions involving the Company or any subsidiary,
division or operating or principal business unit of the Company (such proposal
or offer hereinafter referred to as an "Acquisition Proposal"). However, nothing
shall prohibit the Company or the Company Board of Directors from (i) taking and
disclosing to the Company's shareholders a position with respect to a tender or
exchange offer by a third party pursuant to Rules 14d-9 and 14e-2 promulgated
under the Exchange Act, or (ii) making such disclosure to the Company's
shareholders as, in the good faith judgment of the Company Board of Directors,
after receiving advice from outside counsel, is required under applicable law,
provided that the Company may not, except as detailed below, withdraw or modify,
or propose to withdraw or modify, its position with respect to the Offer or the
Merger or approve or recommend, or propose to approve or recommend any
Acquisition Proposal, or enter into any agreement with respect to any
Acquisition Proposal. Upon execution of the Merger Agreement, the Company will
immediately cease any existing activities, discussions or negotiations with any
parties conducted heretofore with respect to any of the foregoing.
Notwithstanding the foregoing, prior to the time of acceptance of Shares for
payment pursuant to the Offer, the Company may furnish information concerning
its business, properties or assets to any corporation, partnership, person or
other entity or group pursuant to appropriate confidentiality agreements, and
may negotiate and participate in discussions and negotiations with such entity
or group concerning an Acquisition Proposal if: (x) such entity or group has
submitted a Superior Proposal (as defined below); and
                                       20
<PAGE>   23

(y) in the opinion of the Company Board of Directors such action is required to
discharge the Company Board of Director's fiduciary duties to the Company's
shareholders under applicable law, determined only after receipt of a written
opinion from independent legal counsel to the Company that the failure to
provide such information or access or to engage in such discussions or
negotiations would cause the Company Board of Directors to violate its fiduciary
duties to the Company's shareholders under applicable law. The term "Superior
Proposal" means an unsolicited bona fide proposal by a Person (as defined in the
Merger Agreement) to acquire, directly or indirectly, for consideration
consisting of cash and/or securities, all of the Shares then outstanding or all
or substantially all of the assets of the Company or to acquire, directly or
indirectly, the Company by merger or consolidation, and otherwise on terms which
the Company Board of Directors determines in good faith to be more favorable to
the Company's shareholders than the Offer and the Merger (based on the advice of
the Company's independent financial advisor that the value of the consideration
provided for in such proposal is superior to the value of the consideration
provided for in the Offer and the Merger), which is not subject to the receipt
of any necessary financing, and which, in the good faith reasonable judgment of
the Company Board of Directors, is reasonably likely to be consummated.

     The Company has further agreed to immediately notify Parent of the
existence of any proposal, discussion, negotiation or inquiry received by the
Company, and the Company will immediately communicate to Parent the terms of any
proposal, discussion, negotiation or inquiry which it may receive (and will
immediately provide to Parent copies of any written materials received by the
Company in connection with such proposal, discussion, negotiation or inquiry)
and the identity of the party making such proposal or inquiry or engaging in
such discussion or negotiation. The Company will promptly provide to Parent any
non-public information concerning the Company provided to any other party which
was not previously provided to Parent. The Company will keep Parent informed of
the status and details of any such Acquisition Proposal and of any amendments or
proposed amendments to any Acquisition Proposal and will promptly (but in no
case later than 24 hours) notify Parent of any determination by the Company
Board of Directors that a Superior Proposal has been made.

     Pursuant to the Merger Agreement, except as set forth below, neither the
Company Board of Directors nor any committee thereof will (i) withdraw or
modify, or propose to withdraw or modify, in a manner adverse to Parent or
Purchaser, the approval or recommendation by such Board of Directors or any such
committee of the Offer, the Merger Agreement or the Merger, (ii) approve or
recommend or propose to approve or recommend, any Acquisition Proposal or (iii)
enter into any agreement with respect to any Acquisition Proposal.
Notwithstanding the foregoing, prior to the time of acceptance for payment of
Shares pursuant to the Offer, the Company Board of Directors may withdraw or
modify its approval or recommendation of the Offer, the Merger Agreement or the
Merger, approve or recommend a Superior Proposal, or enter into an agreement
with respect to a Superior Proposal, in each case at any time after the fifth
business day following Parent's receipt of written notice from the Company
advising Parent that the Company Board of Directors has received a Superior
Proposal which it intends to accept, specifying the material terms and
conditions of such Superior Proposal, identifying the person making such
Superior Proposal, but only if the Company will have caused its financial and
legal advisors to negotiate with Parent to make such adjustments in the terms
and conditions of the Merger Agreement as would enable the Company to proceed
with the transactions contemplated herein on such adjusted terms.

     Insurance and Indemnification.  For three (3) years after the Effective
Time, Parent and Purchaser will maintain officers' and directors' liability
insurance covering the persons who are presently covered by the Company's
officers' and directors' liability insurance policies with respect to actions
and omissions occurring prior to the Effective Time, on terms which are not
materially less favorable than the terms of such current insurance in effect for
the Company on the date hereof provided, however, that in no event will Parent
or the surviving corporation in the Merger be required to expend in excess of
120% of the annual premium currently paid by the Company for such coverage; and
provided further, that, if the premium for such coverage exceeds such amount,
Parent or the surviving corporation in the Merger shall purchase a policy with
the greatest coverage available for such 120% of the aggregate annual premiums
paid by the Company in 1999.

     For three (3) years after the Effective Time, Parent and Purchaser will
maintain the rights to indemnification of officers and directors provided for in
the By-laws as in effect on the date hereof,
                                       21
<PAGE>   24

with respect to indemnification for acts and omissions occurring prior to the
Effective Time, including without limitation, the transactions contemplated by
the Merger Agreement.

     Conditions to the Merger.  The respective obligation of each party to
effect the Merger will be subject to the satisfaction at or prior to the
Effective Time of each of the following conditions, any and all of which may be
waived in whole or in part by the Company, Parent or Purchaser, as the case may
be, to the extent permitted by applicable law: (i) the Merger Agreement shall
have been approved and adopted by the requisite vote of the holders of Shares,
if required by applicable law, in order to consummate the Merger; (ii) no

Purchaser or their affiliates shall have purchased Shares pursuant to the Offer;
and (iv) the applicable waiting period under the HSR Act shall have expired or
been terminated. "Governmental Body" shall mean any: (a) nation, state, county,

state, local, municipal, commonwealth, possession, foreign or other government;
(c) governmental or quasi-governmental authority of any nature (including any
governmental agency, branch, department, official or entity and any court or
other tribunal); or (d) body exercising, or entitled to exercise, any
administrative, executive, judicial, legislative, police, regulatory or taxing
authority or power of any nature.

     The obligations of Parent and Purchaser to consummate the Merger shall be
subject to the satisfaction on or prior to the Closing Date of each of the
following conditions, any and all of which may be waived in whole or in part by
the Parent and Purchaser, to the extent permitted by applicable law: (i) all
actions required by the Company with respect to the Company stock option plans,
including obtaining the consent of each holder of a Company Option and amending
the terms of the plans have been taken; (ii) all of the representations and
warranties of the Company shall be true in all material respects on the date of

     Termination.  The Merger Agreement, and any related transactions may be
terminated or abandoned at any time prior to the Effective Time, whether before
or after shareholder approval:

          (a) By the mutual written consent of Parent and the Company; provided,
     however, that if Parent shall have a majority of the directors pursuant to
     the applicable provisions of the Merger Agreement, such consent of the
     Company may only be given if approved by the Independent Directors or if
     there are no Independent Directors, then by a unanimous vote of the entire
     Company Board of Directors.

          (b) By either of Parent or the Company: (i) if (x) the Offer shall
     have expired without any Shares being purchased pursuant thereto or (y)
     Purchaser shall not have accepted for payment any Shares pursuant to the
     Offer by December 31, 1999; provided, however, that the right to terminate
     the Merger Agreement under this clause (b) (i) shall not be available to
     any party whose failure to fulfill any obligation under the Merger
     Agreement has been the cause of, or resulted in, the failure of Purchaser
     to purchase the Shares pursuant to the Offer on or prior to such date; or
     (ii) if any Governmental Body shall have issued an order, decree or ruling
     or taken any other action (which order, decree, ruling or other action the
     parties hereto shall use their reasonable efforts to lift), which
     permanently restrains, enjoins or otherwise prohibits the acceptance for
     payment of, or payment for, Shares pursuant to the Offer or the Merger and
     such order, decree, ruling or other action shall have become final and
     non-appealable.

          (c) By the Company: (i) if Parent, Purchaser or any of their
     affiliates shall have failed to commence the Offer on or prior to five (5)
     business days following the date of the initial public announcement of the

     breach of its obligations under the Merger Agreement; (ii) in connection
     with entering into a definitive agreement in accordance with the applicable
     provisions of the Merger Agreement, provided that the Company has complied

     Fee (as defined and discussed below); or (iii) if Parent or
                                       22
<PAGE>   25

     Purchaser shall have terminated the Offer or the Offer expires without
     Parent or Purchaser, as the case may be, purchasing any Shares pursuant
     thereto; provided that the Company may not terminate the Merger Agreement
     under this clause (c)(iii) if the Company is in material breach of the
     Merger Agreement or the Company Option Agreement.

          (d) By Parent: (i) if, due to an occurrence, not involving a breach by
     Parent or Purchaser of their obligations under the Merger Agreement, which
     makes it impossible to satisfy any of the conditions set forth in Section
     14 below, Parent, Purchaser, or any of their affiliates shall have failed
     to commence the Offer on or prior to the fifth business day following the
     date of the initial public announcement of the Offer; (ii) (A) if, prior to
     the purchase of Shares by Purchaser pursuant to the Offer, the Company
     Board of Directors shall have withdrawn, modified or changed in a manner
     adverse to Parent or Purchaser its approval or recommendation of the Offer,
     the Merger Agreement or the Merger or shall have recommended an Acquisition
     Proposal or (B) there shall have been a material breach under any provision
     of the Merger Agreement summarized under "No Solicitation" above, including
     but not limited to the Company having executed an agreement in principle or
     definitive agreement relating to an Acquisition Proposal or similar
     business combination with a person or entity other than Parent, Purchaser
     or their affiliates; (iii) if prior to the purchase of Shares pursuant to
     the Offer, the Company shall have breached any representation, warranty,
     covenant or other agreement contained in the Merger Agreement which would
     give rise to the failure of a condition set forth in Section 14 below; (iv)
     any Person or "group" (as defined in Section 13(d)(3) of the Exchange Act),
     other than Parent, Purchaser or their affiliates or any group of which any
     of them is a member, shall have acquired beneficial ownership (as
     determined pursuant to Rule 13d-3 promulgated under the Exchange Act) of
     15% or more of the Shares or any such Person or group shall have announced
     its intention to acquire 15% or more of the Shares and the Company Board of
     Directors has failed to recommend against acceptance of such announcement
     (including by taking no position with respect to such announcement); (v) if
     the Company receives an Acquisition Proposal from any Person (other than
     Parent or Purchaser), and the Company Board of Directors takes a neutral
     position or makes no recommendation with respect to such Acquisition
     Proposal after a reasonable amount of time (and in no event more than five
     (5) business days following such receipt) has elapsed for the Company Board
     of Directors to review and make a recommendation with respect to such
     Acquisition Proposal; or (vi) if Parent or Purchaser shall have terminated
     the Offer in accordance with the terms of the Merger Agreement without
     Parent or Purchaser purchasing any Shares thereunder, provided that Parent

     Termination Fee; Expenses.  Pursuant to the Merger Agreement, if (x) the
Company enters into an agreement which accepts or implements a Superior
Proposal; (y) the Company terminates or abandons the Merger Agreement, the
Offer, the Merger and the transactions contemplated thereby (the

pursuant to clause (c)(ii) under the heading "Termination" above; or (z) Parent
terminates or abandons the Transactions pursuant to clauses (d)(ii), (iv) or (v)
under the heading "Termination" above, then the Company will pay to Parent an
amount equal to $2 million (the "Termination Fee"). The Termination Fee will be
paid in same day funds concurrently with the execution of an agreement referred
to in clause (x) above or any termination or abandonment referred to in clauses
(y) or (z) above, whichever occurs first. If the Merger Agreement is terminated
by Parent pursuant to clause (d)(iii) under the heading "Termination" above and
at the time of such termination, (i) the Company has not paid the Termination
Fee, and (ii)Parent is not in material breach of the Merger Agreement, then the

(iii) or (vi) under the heading "Termination" above and prior thereto there
shall have been publicly announced another Acquisition Proposal, (b) the Merger
Agreement is terminated by the Company pursuant to clause (c)(iii) under the
heading "Termination" above and prior thereto there shall have been publicly
announced another Acquisition

Proposal or (c) either the Company or Parent terminates or abandons the
Transactions pursuant to clause (b)(i) under the heading "Termination" above and
prior thereto there shall have been publicly announced another Acquisition
Proposal, and, in each such case, at the time of such termination (i) the
Company has not paid the Termination Fee, and (ii) Parent is not in material
breach of the Merger Agreement and within 12 months after such termination the
Company shall enter into an agreement with respect to an Acquisition Proposal,
then concurrently with the consummation of the transactions contemplated by such

Termination Fee and the Expenses, previously paid (if any).

  Company Option Agreement

     The following is a summary of certain provisions of the Company Option
Agreement. This summary is not a complete description of the terms and
conditions of the Company Option Agreement and is qualified in its entirety by
reference to the full text of the Company Option Agreement, which is
incorporated herein by reference and a copy of which has been filed with the
Commission as an exhibit to the Schedule 14D-1. The Company Option Agreement may
be examined, and copies obtained, in the manner set forth in Sections 8 and 9 of
this Offer to Purchase.

     Grant of Option.  The Company Option Agreement provides for the grant by
the Company to Parent of an irrevocable option (the "Stock Option") to purchase
up to 19.9% of the number of Shares (the "Option Shares") issued at the time of
the grant of the Stock Option, at a price of $5.50 per Share (the "Exercise
Price"), payable in cash in accordance with the terms of the Company Option
Agreement.

     Exercise of Option.  The Company Option Agreement provides that the Stock
Option may be exercised by Parent, in whole or in part, at any time or from time
to time after the Merger Agreement becomes terminable pursuant to a Triggering
Event (as defined below). For the purposes of the Company Option Agreement,
"Triggering Event" means any termination of the Merger Agreement which entitles
Parent to the Termination Fee under the Merger Agreement.

     Cash Payment.  If, at any time during the period commencing on the
occurrence of a Triggering Event and ending on the termination of the Stock
Option in accordance with the provisions of the Company Option Agreement, Parent
sends to the Company a notice indicating Parent's election to exercise its right
(the "Cash-Out Right") described in this paragraph, then the Company shall pay
to Parent, in exchange for the cancellation of the Stock Option with respect to
such number of Option Shares as Parent specifies an amount in cash equal to the
amount by which (A) the highest of (i) the price per share of the Shares at
which a tender offer or exchange offer therefor has been made, (ii) the highest
price per share of the Shares to be paid by any third party pursuant to an
agreement with the Company, (iii) the highest closing price per Share within the
six-month period immediately preceding the date Parent sent to the Company its
notice to exercise its right and (iv) in the event of a sale of all or a
substantial portion of the Company's assets, the sum of the price paid in such
sale for such assets and the current market value of the remaining assets of the
Company divided by the number of Shares outstanding at the time of such sale,
exceeds (B) the Exercise Price, multiplied by the number of shares for which the
Stock Option is then exercised.

     If the aggregate amount received by Parent from (i) the Termination Fee and
Expenses pursuant to the applicable provisions of Merger Agreement, (ii) amounts
from the sale or other disposition of the Option Shares, and (iii) amounts paid
pursuant to the Company Option Agreement as described in the above paragraph,
are in excess of the sum of (A) $2,000,000 plus (B) the aggregate amounts paid
by Parent to purchase any Option Shares, then Parent, at its sole election,
shall either (1) reduce the number of Option Shares, (2) deliver to the Company
for cancellation Option Shares previously purchased by Parent, (3) pay cash to
the Company or (4) any combination thereof, so that the amount received by
Parent pursuant to clauses (i), (ii) and (iii) above shall not exceed the sum of
the amounts in clauses (A) and (B) above after taking into account the foregoing
actions.

     Termination of Option.  The Company Option Agreement provides that the
Stock Option will terminate upon the earlier of: (i) the purchase of Shares
pursuant to the Offer; (ii) twelve months after the date on which a Triggering
Event occurs; or (iii) the termination of the Merger Agreement in accordance
with its terms prior to the occurrence of a Triggering Event, unless, in the
case of clauses (ii) and (iii), Parent could

                                       24
<PAGE>   27

be entitled to receive the Termination Fee following such time of termination
upon the occurrence of certain events, in which case the Stock Option will not
terminate until the later of (x) twelve months following the time such fees
become payable and (y) the expiration of the period in which Parent has such
right to receive the Termination Fee.

     Registration Rights.  The Company Option Agreement provides that Parent,
within three years, may, by written notice to the Company, request that the
Company register under the Securities Act all or any part of the Shares
beneficially owned by Parent in order to permit the sale or other disposition of
such securities pursuant to (a) a shelf registration or (b) a bona fide, firm
commitment underwritten public offering.

     Adjustment upon Changes in Capitalization.  The Company Option Agreement
provides that in the event of any change in the Shares by reason of stock
dividends, stock splits, reverse stock splits, mergers (other than the Merger),
recapitalizations, combinations, exchange of shares or similar transaction, the
type and number of shares or securities subject to the Stock Option, and the
Exercise Price per share, will be adjusted appropriately and proper provision
will be made so that Parent will receive upon exercise of the Stock Option the
number and class of shares or other securities or property that Parent would
have received with respect to the Shares if the Stock Option had been exercised
immediately prior to such event or the record date therefor, as applicable.

  The Shareholder Agreements

     Concurrently with the execution and delivery of the Merger Agreement, each
of the Director Shareholders entered into a Shareholder Agreement pursuant to
which each Director Shareholder has agreed to tender in the Offer all Shares
beneficially owned by such Director Shareholder (719,764 Shares in the
aggregate) which will result in the Parent and its affiliates beneficially
owning 10.1% of the outstanding Shares.

     Each Shareholder Agreement provides that, within five business days of the
commencement of the Offer, each Director Shareholder will tender to the
Depositary all of the Shares required to be tendered pursuant to the applicable
Shareholder Agreement. Subject to applicable law, a Director Shareholder may not
withdraw any Shares so tendered by him; provided, however, that a Director
Shareholder may decline to tender his Shares, or may withdraw Shares tendered by
him, if the Purchaser amends the Offer to (a) reduce the Offer Price to less
than $5.50 per Share in cash; (b) reduce the number of Shares subject to the
Offer; (c) change the form of consideration payable for Shares pursuant to the
Offer; or (d) amend or modify any term or condition of the Offer in a manner
adverse to the shareholders of the Company.

     Under the Shareholder Agreements, each Director Shareholder grants to
Parent an option to purchase the Shares beneficially owned by such Director
Shareholder at a purchase price per Share of $5.50 or such higher price as may
be offered in the Offer. Provided all waiting periods under the HSR Act and the
rules and regulations thereunder applicable to the purchase of Shares pursuant
an option shall have expired or been terminated and there shall otherwise be no
legal restriction on the exercise of an option, an option may be exercised by
Parent in whole or in part at any time prior to the date 60 days after the
Expiration Date or termination of the Offer if (a) the Director Shareholder who
granted such option fails to comply with any of his obligations under his
Shareholder Agreement or withdraws a tender of its Shares in violation of the
provisions of his Shareholder Agreement or (b) the Offer is not consummated
because of the failure to satisfy any of the conditions to the Offer described
in Section 14 (other than as a result of any action or inaction on the part of
the Parent or the Purchaser which constitutes a breach of the Merger Agreement).

     Under the Shareholder Agreements the Purchaser may allow the Offer to
expire without accepting for payment or paying for any Shares, on the terms set
forth in the Offer, and may allow the option to expire without exercising the
option and purchasing all or any Shares pursuant to such exercise. If all Shares
validly tendered and not withdrawn are not accepted for payment and paid for in
accordance with the terms of the Offer or pursuant to the exercise of the
option, they shall be returned to the applicable Director Shareholders whereupon
they shall continue to be held by such Director Shareholder subject to the terms
of the applicable Shareholder Agreement.

                                       25
<PAGE>   28

     Each of the Director Shareholders have agreed in the Shareholder Agreements
(a) to revoke any and all previous proxies granted by such Director Shareholders
with respect to the Shares beneficially owned by such Director Shareholders and,
for so long as the Merger Agreement remains in effect; (b) to vote the number of
Shares beneficially owned by such Director Shareholder, in favor of the Articles
Amendment, the Merger Agreement, the Merger and the transactions contemplated
thereby, and (c) to oppose and vote such number of Shares against any
Acquisition Proposal. The Director Shareholders have further agreed not to
solicit, initiate or knowingly encourage any Acquisition Proposal.

     Each Shareholder Agreement will expire and be of no further force or effect
if (a) the conditions to the Purchaser's obligations to accept for payment and
pay for Shares pursuant to the Offer shall have been satisfied and the Purchaser
fails to promptly accept for payment and promptly pay for all Shares validly
tendered and not withdrawn pursuant to the Offer or (b) the Purchaser amends the
Offer to (i) reduce the Offer Price to less than $5.50 per Share in cash; (ii)
reduce the number of Shares subject to the Offer; (iii) change the form of
consideration payable for Shares pursuant to the Offer; or (iv) amend or modify
any term or condition of the Offer in a manner adverse to the shareholders of
the Company. Each Shareholder Agreement will also terminate upon the earlier of
(i) the close of business on March 1, 2000 or (ii) the Effective Time.

     In the case of the Shareholder Agreement of Mr. Grant R. Meyers, the
parties thereto have acknowledged that a portion of the Shares subject to such
agreement are pledged to various persons and Mr. Meyer's obligations under his
Shareholder Agreement are subject to any applicable restrictions in the pledge
agreements with such persons.

     The following is a summary of certain provisions of the Confidentiality
Agreement entered into on February 25, 1999 by Parent and the Company (the

  Employment Agreements

     The following is a summary of certain provisions of the employment
agreements entered into on July 12, 1999 between Parent and Steven L. Schneider
(the "Schneider Agreement") and the Company and Calvin J. Monsma (the "Monsma

1999, Parent and the Company entered into the Employment Agreements.

     Schneider Agreement. The Schneider Agreement replaces and supercedes
Schneider's existing employment agreement with the Company, including the change
of control provisions thereof. The effectiveness of the Schneider Agreement is
conditioned upon the consummation of the Offer. Pursuant to the Schneider

Chairman and Chief Executive

                                       26

Officer of Parent's Indoor Air Quality unit until August 31, 2002. The Schneider
Agreement will be automatically extended for an additional year as of August 31,
2002 and on each anniversary thereof unless either party gives written notice of
termination at least 180 days prior to any such date.

     The Agreement provides for a base salary of $214,000 per year (the
"Schneider Base Salary"), subject to review and adjustment by the Board of
Directors of Parent or the compensation committee of Parent. Schneider's
compensation will also include an annual discretionary incentive bonus equal to
50% of the Schneider Base Salary based on the performance of the Indoor Air
Quality unit and certain individual performance targets established by the chief
executive officer of Parent. In addition, Schneider will receive as incentive
compensation an amount equal to  1/4% of the total purchase price of
acquisitions of businesses included in the Indoor Air Quality unit.

     Pursuant to the Schneider Agreement, at the Effective Time, Schneider will
be granted options to purchase 100,000 shares of the Class A Stock of Parent at
an exercise price equal to the closing price of the Class A Stock on such date.
The Schneider Agreement provides that one third of the options will vest each
year on the anniversary date of the Schneider Agreement.

     In the event of Schneider's death, disability or resignation or discharge
by Parent other than a termination without "cause" (as defined in the Schneider
Agreement) or resignation with "good reason" (as defined in the Schneider
Agreement), Parent will pay Schneider: (i) all accrued obligations including the
Schneider Base Salary through the date of termination, and (ii) all accrued
benefits under Parent's retirement, incentive or other benefit plans. In the
event of a termination without cause or resignation with good reason, (i) Parent
will pay Schneider all accrued obligations including the Schneider Base Salary
through the date of termination; (ii) Parent will pay Schneider a lump sum equal
to the balance of the Schneider Base Salary and any incentive compensation then
in effect for the remainder of the term of the Schneider Agreement; (iii) an
amount equal to the maximum contributions that could have been made by Parent on
Schneider's behalf to all defined contribution plans of Parent on the same basis
as in effect on the date of termination of the Schneider Agreement for the
remainder of the term of the Schneider Agreement shall be paid to the trustees
of such plan(s); however, in the event any such plan(s) will not allow such
payment, Parent will pay to Schneider a lump sum in cash equal to the total
amount not accepted by such plan(s); (iv) Schneider shall be entitled to receive
all benefits accrued by him under the retirement, incentive or other benefit
plans in which Schneider was participating; (v) Parent will pay all premiums
under COBRA for Schneider and his dependents if they elect coverage and (vi) in
the event Schneider is so terminated or resigns during the initial three year
term of the Schneider Agreement, any unvested Parent stock options granted
Schneider pursuant to the Schneider Agreement shall vest immediately and
Schneider shall have 30 days to exercise such options.

     Monsma Agreement.  The Monsma Agreement replaces and supercedes Monsma's
existing change of control agreement with the Company. The effectiveness of the
Monsma Agreement is conditioned upon the consummation of the Offer. Pursuant to
the Monsma Agreement, Monsma will serve as a Vice President and Chief Financial
Officer of the Company until August 31, 2002. The Monsma Agreement will be
automatically extended for an additional year as of August 31, 2002 and on each
anniversary thereof unless either party gives written notice of termination at
least 90 days prior to any such date.

     The Agreement provides for a base salary of $113,400 per year (the "Monsma
Base Salary"), subject to review and adjustment by the Company. Monsma's
compensation will also include an annual discretionary bonus equal to 35% of the
Monsma Base Salary which will be based on the performance of the Company and
certain individual performance targets established by the chief executive
officer of Parent's Indoor Air Quality unit. In addition, Monsma will receive as
incentive compensation an amount equal to  1/8% of the total purchase price of
acquisitions of businesses by the Company.

     Pursuant to the Monsma Agreement, at the Effective Time, Monsma will be
granted options to purchase 25,000 shares of the Class A Stock of Parent at an
exercise price equal to the closing price of the Class A Stock on such date. The

     In the event of Monsma's death, disability or resignation or discharge by
the Company other than a termination without "cause" (as defined in the Monsma
Agreement) or resignation with good reason (as defined in the Monsma Agreement),
the Company will pay Monsma: (i) all accrued obligations including the Monsma
Base Salary through the date of termination, and (ii) all accrued benefits under

12. PLANS FOR THE COMPANY; OTHER MATTERS.

  Plans for the Company

     If, as and to the extent that Purchaser acquires control of the Company,
Parent and Purchaser intend to conduct a detailed review of the Company and its
assets, corporate structure, capitalization, operations, properties, policies,
management and personnel and to consider and determine what, if any, changes
would be desirable in light of the circumstances which then exist. Such changes
could include, among other things, changes in the Company's business, corporate
structure, articles of incorporation, By-laws, capitalization, management or
dividend policy.

     Following consummation of the Merger, Parent currently intends to effect a
merger (the "Reincorporation Merger") of the Company with a subsidiary of Parent
that is incorporated in the State of Delaware as a result of which the Company
will be incorporated in the State of Delaware.

     The Merger Agreement provides that, upon the purchase of and payment for
any Shares by Parent or any of its subsidiaries pursuant to the Offer, Parent
shall be entitled to designate such number of directors, rounded up to the next
whole number, on the Company Board of Directors to the product of the total
number of directors on such Company Board of Directors (giving effect to the
directors designated by Parent pursuant to this sentence) multiplied by an
amount of which the numerator is the number of Shares which Parent and its
subsidiaries own and the denominator is the total number of Shares outstanding.
See Section 11. Assuming the Minimum Condition is satisfied and Purchaser
purchases Shares pursuant to the Offer, Parent intends to promptly exercise such
rights by causing the Company to elect to the Company Board of Directors Messrs.
Sal Giordano, Jr., Robert Laurent, Jr., Michael Giordano, Kent Hanson, Steven
Schneider and Calvin Monsma. Information with respect to such directors is
contained in Schedule I hereto and in the Information Statement required by Rule
14f-1 under the Exchange Act included as Annex I to the Schedule 14D-9. The
Merger Agreement provides that the directors of Purchaser and the officers of
the Company at the Effective Time of the Merger will, from and after the
Effective Time, be the directors and officers, respectively, of the Surviving
Corporation.

     Purchaser or an affiliate of Purchaser may, following the consummation or
termination of the Offer, seek to acquire additional Shares through open market
purchases, privately negotiated transactions, a tender offer or exchange offer
or otherwise, upon such terms and at such prices as it shall determine, which
may be more or less than the price to be paid pursuant to the Offer. Purchaser
and its affiliates also reserve the right to dispose of any or all Shares
acquired by them, subject to the terms of the Merger Agreement.
                                       28
<PAGE>   31

     Except as disclosed in this Offer to Purchase, and except for the
Reincorporation Merger and as may be effected in connection with the integration
of operations referred to above, neither Parent nor Purchaser has any present
plans or proposals that would result in an extraordinary corporate transaction,
such as a merger, reorganization, liquidation, relocation of operations, or sale
or transfer of a material amount of assets, involving the Company or any of its
subsidiaries, or any material changes in the Company's capitalization, corporate
structure, business or composition of its management or the Company Board of
Directors.

     Appraisal Rights.  Notwithstanding anything in the Merger Agreement to the
contrary, any issued and outstanding Shares held by persons who object to the
Merger and comply with all the provisions of the PBCL concerning the right of
holders of Shares to dissent from the Merger and require appraisal of their
Shares ("Dissenting Shareholder") will not be converted into the right to
receive the Offer Price, without interest, pursuant to the Merger Agreement, but
will be converted into the right to receive such consideration as may be
determined to be due to such Dissenting Shareholder pursuant to the PBCL;
provided, however, that the Shares outstanding immediately prior to the
Effective Time and held by a Dissenting Shareholder who will, after the
Effective Time, withdraw his demand for appraisal or lose his right of
appraisal, in either case pursuant to the PBCL, will be deemed to be converted
as of the Effective Time into the right to receive the Offer Price, payable to
the holder thereof, without interest. The Company will give Parent (i) prompt
notice of any written demands for appraisal of the Shares received by the
Company and (ii) the opportunity to direct all negotiations and proceedings with
respect to any such demands. The Company will not, without the prior written
consent of Parent, voluntarily settle or compromise any such demands.

     In addition to the appraisal rights discussed above, shareholders also have
certain rights ("Subchapter 25E Rights") under Subchapter 25E of the PBCL
("Subchapter 25E") which will become applicable prior to the Effective Time in
the event that the Purchaser (or a group of related persons, or any other person
or group of related persons) were to acquire Shares representing at least 20% of
the voting power of the Company, in connection with the Offer or otherwise (a
"Control Transaction"). In such event, shareholders of the Company would have
the right to demand "fair value" of such shareholders' Shares and to be paid
such fair value upon compliance with the requirements of Subchapter 25E. Under
Subchapter 25E, "fair value" may not be less than the highest price per share
paid by the controlling person or group at any time during the 90-day period
ending on and including the date of the Control Transaction, plus an increment,
if any, representing any value, including, without limitation, any proportion of
value payable for acquisition of control of the Company, that may not be
reflected in such price. Purchaser believes that the Offer Price represents fair
value of the Shares within the meaning of Subchapter 25E. Subchapter 25E Rights
would attach immediately upon consummation of a Control Transaction and require
that any shareholder seeking such appraisal must make a demand for fair value
within a reasonable time after the notice to shareholders that a Control
Transaction has occurred is given by the controlling person or group in
accordance with Subchapter 25E, which time period may be specified in such
notice, as well as comply with the other procedures of Subchapter 25E.
Subchapter 25E Rights are available only with respect to shares of a registered
corporation held by a shareholder after the occurrence of a Control Transaction;
accordingly, Subchapter 25E Rights would not be available with respect to any
Shares tendered in the Offer and accepted for payment. The foregoing summary of
rights under Subchapter 25E is qualified in its entirety by reference to the
full text of Subchapter 25E, which is attached hereto as Annex A.

     THE FOREGOING SUMMARY OF THE RIGHTS OF DISSENTING SHAREHOLDERS UNDER THE
PBCL DOES NOT PURPORT TO BE A COMPLETE STATEMENT OF THE PROCEDURES TO BE
FOLLOWED BY SHAREHOLDERS DESIRING TO EXERCISE ANY APPRAISAL RIGHTS AVAILABLE
UNDER THE PBCL. THE PRESERVATION AND EXERCISE OF APPRAISAL RIGHTS REQUIRE STRICT
ADHERENCE TO THE APPLICABLE PROVISIONS OF THE PBCL.

     Rule 13e-3.  The Commission has adopted Rule 13e-3 under the Exchange Act
which is applicable to certain "going private" transactions and which may under
certain circumstances be applicable to the Merger or another business
combination following the purchase of Shares pursuant to the Offer in which
Purchaser seeks to acquire the remaining Shares not held by it. Purchaser
believes, however, that Rule 13e-3 will not be applicable to the Merger because
it is anticipated that the Merger would be effected within one year following
consummation of the Offer and in the Merger shareholders would receive the same
price per Share as paid in
                                       29
<PAGE>   32

the Offer. If Rule 13e-3 were applicable to the Merger, it would require, among
other things, that certain financial information concerning the Company, and
certain information relating to the fairness of the proposed transaction and the
consideration offered to minority shareholders in such a transaction, be filed
with the Commission and disclosed to minority shareholders prior to consummation
of the transaction.

13. DIVIDENDS AND DISTRIBUTIONS.

     As described above, the Merger Agreement provides that from the date of the
execution of the Merger Agreement until the Effective Time, without the prior
written consent of Parent, the Company will not: (a) change the authorized or
issued capital stock of the Company or any subsidiary of the Company; (b) grant
any stock option or right to purchase shares of capital stock of the Company or
any subsidiary of the Company; (c) issue any security convertible into such
capital stock; (d) grant any registration rights with respect to such capital
stock; (e) purchase, redeem, retire or otherwise acquire any shares of any such
capital stock (nor shall any subsidiary of the Company do so); or (f) declare or
pay any dividend or other distribution or payment in respect of shares of any
such capital stock.

14. CONDITIONS TO THE OFFER.

     Notwithstanding any other provisions of the Offer, and in addition to (and
not in limitation of) Purchaser's rights to extend and amend the Offer at any
time in its sole discretion (subject to the provisions of the Merger Agreement),
Purchaser shall not be required to accept for payment or, subject to any
applicable rules and regulations of the Commission, including Rule 14e-1(c)
under the Exchange Act (relating to Purchaser's obligation to pay for or return
tendered Shares promptly after termination or withdrawal of the Offer), pay for,
and may delay the acceptance for payment of or, subject to the restriction
referred to above, the payment for, any tendered Shares, and may terminate or
amend the Offer as to any Shares not then paid for, if (i) any applicable
waiting period under the HSR Act has not expired or terminated, (ii) the Minimum
Condition has not been satisfied, or (iii) at any time on or after the date of
the Merger Agreement and before the Expiration Date, any of the following events
shall occur or shall be determined by Purchaser to have occurred:

          (a)(i) there shall be threatened, instituted or pending any suit,
     action or proceeding by any Governmental Body or (ii) there shall be
     instituted or pending any suit, action or proceeding before any court which
     in the good faith judgement of Parent and Purchaser is likely to result in
     any change or effect (or any development that, insofar as can reasonably be
     foreseen, is likely to result in any change or effect) that is materially
     adverse to the business, properties, assets, prospects, financial condition
     or results of operations of the Company and its subsidiaries taken as a
     whole or the ability of the Company to consummate the Merger Agreement, the
     Company Option Agreement, the Offer, the acquisition of shares pursuant to
     the Offer, the Shareholder Agreements, the Company Option Agreement and the
     Merger (a "Material Adverse Effect" or "Material Adverse Change"), in each
     case of (i) or (ii), (A) seeking to prohibit or impose any limitations on
     Parent's or Purchaser's ownership or operation (or that of any of their
     respective subsidiaries or Affiliates) of all or a material portion of
     their or the Company's businesses or assets, or to compel Parent or
     Purchaser or their respective subsidiaries and Affiliates to dispose of or
     hold separate any material portion of the business or assets of the Company
     or Parent and their respective subsidiaries, in each case taken as a whole,
     (B) challenging the acquisition by Parent or Purchaser of any Shares under
     the Offer or pursuant to the Company Option Agreement or the Shareholder
     Agreements seeking to restrain, prohibit or delay the making or
     consummation of the Offer or the Merger or the performance of any of the
     other transactions contemplated by the Merger Agreement, the Company Option
     Agreement or the Shareholder Agreements, or seeking to obtain from the
     Company, Parent or Purchaser any damages that are material in relation to
     the Company and its subsidiaries taken as a whole, (C) seeking to impose
     material limitations on the ability of Parent or Purchaser, or rendering
     Parent or Purchaser unable, to accept for payment, pay for or purchase some
     or all of the Shares pursuant to the Offer and the Merger, (D) seeking to
     impose limitations on the ability of Purchaser or Parent effectively to
     exercise full rights of ownership of the Shares, including, without
     limitation, the right to vote the Shares purchased by it on all matters
     properly presented to the Company's

                                       30
<PAGE>   33

     shareholders, (E) seeking to restrict any future business activity by
     Parent or Purchaser, including, without limitation, requiring the prior
     consent of any person or entity (including any Governmental Body) to future
     transactions by Parent or Purchaser, or (F) which otherwise is reasonably
     likely to have a Material Adverse Effect on the Company or, as a result of
     the Transactions, Parent and its subsidiaries; or

          (b) there shall be any statute, rule, regulation, judgment, order or
     injunction enacted, entered, enforced, promulgated or deemed applicable to
     the Offer or the Merger, or any other action shall be taken by any
     Governmental Body, other than the application to the Offer or the Merger of
     applicable waiting periods under the HSR Act, that is reasonably likely to
     result, directly or indirectly, in any of the consequences referred to in
     clauses (A) through (F) of paragraph (a) above; or

          (c) there shall have occurred (i) any general suspension of trading
     in, or limitation on prices for, securities on the NYSE or on the Nasdaq
     (excluding (A) suspensions or limitations resulting solely from physical
     damage or interference with such exchanges not related to market conditions
     and (B) limitations on price fluctuations in effect on the date of the
     Merger Agreement), or (ii) a declaration of a banking moratorium by federal
     or state authorities or any suspension of payments in respect of banks in
     the United States (whether or not mandatory) imposed by federal or state
     authorities on the extension of credit by lending institutions in the
     United States; or

          (d) there shall have occurred any Material Adverse Change (or any
     development that, insofar as reasonably can be foreseen, is reasonably
     likely to result in any Material Adverse Change); or

          (e) the Company Board of Directors or any committee thereof (i) shall
     have withdrawn, modified or changed in a manner adverse to Parent or
     Purchaser its approval or recommendation of the Offer, the Merger Agreement
     or the Merger, (ii) shall have recommended the approval or acceptance of an
     Acquisition Proposal from, or similar business combination with, a person
     or entity other than Parent, Purchaser or their Affiliates, (iii) shall
     have executed an agreement in principle or definitive agreement relating to
     an Acquisition Proposal from, or similar business combination with, a
     person or entity other than Parent, Purchaser or their Affiliates or (iv)
     upon request of Purchaser, shall fail to reaffirm its approval or
     recommendation of the Offer, the Merger Agreement, or the Merger; or

          (f) the Company shall have breached or failed to perform any of its
     agreements under the Company Option Agreement or breached any of its
     representations and warranties in such agreement or such agreement shall
     not be valid, binding and enforceable, except for such breaches or failures
     or failures to be valid, binding and enforceable that do not materially and
     adversely affect the benefits expected to be received by Parent and
     Purchaser under the Merger Agreement or the Company Option Agreement; or

          (g) any Person or "group" (as defined in Section 13(d)(3) of the
     Exchange Act), other than Parent, Purchaser or their affiliates or any
     group of which any of them is a member, shall have acquired beneficial
     ownership (as determined pursuant to Rule 13d-3 promulgated under the
     Exchange Act) of 15% or more of the Shares or any such Person or group
     shall have announced its intention to acquire 15% or more of the Shares and
     the Company Board of Directors has failed to recommend against acceptance
     of such announcement (including by taking no position with respect to such
     announcement); or

          (h) any of the representations and warranties of the Company set forth
     in the Merger Agreement that are qualified as to materiality shall not be
     true and correct and any such representations and warranties that are not
     so qualified shall not be true and correct in any material respect, in each
     case as of the date of the Merger Agreement and as of the scheduled
     expiration of the Offer; or

          (i) the Company shall have breached or failed to perform or to comply
     with any obligation, agreement or covenant of the Company to be performed
     or complied with by it under the Merger Agreement; except, in each case
     where the failure to perform or comply with such obligations, agreements or
     covenants, does not, individually or in the aggregate, have a Material
     Adverse Effect on the Company or a Material Adverse Effect on the ability
     of the Company to consummate the Offer or the Merger; or

                                       31
<PAGE>   34

          (j) all consents necessary to the consummation of the Offer or the
     Merger including, without limitation, consents from parties to loans,
     contracts, leases or other agreements and consents from governmental
     agencies, whether federal, state or local shall not have been obtained,
     other than consents the failure to obtain which would not have a Material
     Adverse Effect; or

          (k) the Employment Agreements shall not be in full force and effect
     and either Schneider or Monsma shall have denied or disaffirmed his
     obligation under his respective Employment Agreement; and

          (l) the Merger Agreement shall have been terminated in accordance with
     its terms;

which in the reasonable good faith judgment of Parent or Purchaser, in any such
case, and regardless of the circumstances (including any action or inaction by
Parent or Purchaser) giving rise to such condition makes it inadvisable to
proceed with the Offer and/or with such acceptance for payment of or payment for
Shares.

     The foregoing conditions are for the sole benefit of Parent and Purchaser,
may be waived by Parent or Purchaser, in whole or in part, at any time and from
time to time in the sole discretion of Parent or Purchaser. The failure by
Parent or Purchaser at any time to exercise any of the foregoing rights shall
not be deemed a waiver of any such right and each such right shall be deemed an
ongoing right which may be asserted at any time and from time to time.

15. CERTAIN LEGAL MATTERS.

     General.  Except as described in this Section 15, based on information
provided by the Company, neither the Company, Purchaser nor Parent is aware of
any license or regulatory permit that appears to be material to the business of
the Company and its subsidiaries, taken as a whole, that might be adversely
affected by the acquisition of Shares by Parent or Purchaser pursuant to the
Offer, the Merger or otherwise or any approval or other action by any
governmental, administrative or regulatory agency or authority, domestic or
foreign, that would be required prior to the acquisition of Shares by Purchaser
pursuant to the Offer, the Merger or otherwise. Should any such approval or
other action be required, Purchaser and Parent presently contemplate that such
approval or other action will be sought, except as described below under "State
Takeover Laws." While, except as otherwise described in this Offer to Purchase,
Purchaser does not presently intend to delay the acceptance for payment of, or
payment for, Shares tendered pursuant to the Offer pending the outcome of any
such matter, there can be no assurance that any such approval or other action,
if needed, would be obtained or would be obtained without substantial conditions
or that failure to obtain any such approval or other action might not result in
consequences adverse to the Company's business or that certain parts of the
Company's business might not have to be disposed of, or other substantial
conditions complied with, in the event that such approvals were not obtained or
such other actions were not taken or in order to obtain any such approval or
other action. If certain types of adverse action are taken with respect to the
matters discussed below, Purchaser could decline to accept for payment, or pay
for, any Shares tendered. See Section 14 for certain conditions to the Offer,
including conditions with respect to governmental actions.

     State Takeover Laws.  A number of states throughout the United States have
enacted takeover statutes that purport, in varying degrees, to be applicable to
attempts to acquire securities of corporations that are incorporated or have
assets, shareholders, executive offices or places of business in such states. In
Edgar v. MITE Corp., the Supreme Court of the United States held that the
Illinois Business Takeover Act, which involved state securities laws that made
the takeover of certain corporations more difficult, imposed a substantial
burden on interstate commerce and therefore was unconstitutional. In CTS Corp.
v. Dynamics Corp. of America, however, the Supreme Court of the United States
held that a state may, as a matter of corporate law and, in particular, those
laws concerning corporate governance, constitutionally disqualify a potential
acquirer from voting on the affairs of a target corporation without prior
approval of the remaining shareholders, provided that such laws were applicable
only under certain conditions.

     The Pennsylvania Takeover Disclosure Law ("PTDL") purports to regulate
certain attempts to acquire a corporation which (1) is organized under the laws
of Pennsylvania or (2) has its principal place of business and substantial
assets located in Pennsylvania. In Crane Co. v. Lam, 509 F. Supp. 782 (E.D. Pa.
1981), the

                                       32
<PAGE>   35

United States District Court for the Eastern District of Pennsylvania
preliminarily enjoined, on grounds arising under the United States Constitution,
enforcement of at least the portion of the PTDL involving the pre-offer waiting
period thereunder. Section 8(a) of the PTDL provides an exemption for any offer
to purchase securities as to which the board of directors of the target company
recommends acceptance to its shareholders, if at the time such recommendation is
first communicated to shareholders the offeror files with the Pennsylvania
Securities Commission ("PSC") a copy of the Schedule 14D-1 and certain other
information and materials, including an undertaking to notify security holders
of the target company that a notice has been filed with the PSC which contains
substantial additional information about the offering and which is available for
inspection at the PSC's principal office during business hours. The Company
Board of Directors by the unanimous vote of those present at the meeting has
approved the transactions contemplated by the Merger Agreement and recommended
acceptance of the Offer and the Merger to the Company's shareholders. While
reserving and not waiving its right to challenge the validity of the PTDL or its
applicability to the Offer, Purchaser is making a Section 8(a) filing with the
PSC in order to qualify for the exemption from the PTDL. Pursuant to Section 10
of the PTDL, Purchaser will submit the appropriate $100 notice filing fee along
with the Section 8(a) filing. Additional information about the Offer has been
filed with the PSC pursuant to the PTDL and is available for inspection at the
of the PSC office at Eastgate Office Building, 1010 North 7th Street,
Harrisburg, PA 17102-1410, during business hours.

     Chapter 25 of the PBCL contains other provisions relating generally to
takeovers and acquisitions of certain publicly owned Pennsylvania corporations
such as the Company that have a class or series of shares entitled to vote
generally in the election of directors of the Corporation registered under the
Exchange Act (a "registered corporation"). The following discussion is a general
and highly abbreviated summary of certain features of such chapter, is not
intended to be complete or to completely address potentially applicable
exceptions or exemptions, and is qualified in its entirety by reference to
Chapter 25 of the PBCL.

     In addition to other provisions not applicable to the Offer or the Merger,
Subchapter 25D of the PBCL includes provisions requiring approval of a merger of
a registered corporation with an "interested shareholder" in which the
"interested shareholder" is treated differently from other shareholders, by the
affirmative vote of the shareholders entitled to cast at least a majority of the
votes that all shareholders other than the interested shareholder are entitled
to cast with respect to the transaction without counting the votes of the
interested shareholder. This disinterested shareholder approval requirement is
not applicable to a transaction (i) approved by a majority of disinterested
directors, (ii) in which the consideration to be received by shareholders is not
less than the highest amount paid by the interested shareholder in acquiring his
shares, or (iii) effected without submitting the merger to a vote of
shareholders as permitted in Section 1924(b)(1)(ii) of the PBCL. Purchaser
currently believes that the disinterested shareholder approval requirement of
Subchapter 25D will not be applicable to the contemplated Merger because of
prior approval of the disinterested members of the Company Board of Directors.

     Shareholders will also have certain rights under Subchapter 25E of the PBCL
which will become applicable prior to the Effective Time in the event of a
Control Transaction. In such event, shareholders of the Company would have the
right to demand "fair value" of such shareholders' Shares and to be paid such
fair value upon compliance with the requirements of Subchapter 25E. Under
Subchapter 25E, "fair value" may not be less than the highest price per share
paid by the controlling person or group at any time during the 90-day period
ending on and including the date of the Control Transaction, plus an increment,
if any, representing any value, including, without limitation, any proportion of
value payable for acquisition of control of the Company, that may not be
reflected in such price. Purchaser believes that the Offer Price represents fair
value of the Shares within the meaning of Subchapter 25E. Subchapter 25E Rights
would attach immediately upon consummation of a Control Transaction and require
that any shareholder seeking such appraisal must make a demand for fair value
within a reasonable time after the notice to shareholders that a Control
Transaction has occurred is given by the controlling person or group in
accordance with Subchapter 25E, which time period may be specified in such
notice, as well as comply with the other procedures of Subchapter 25E.
Subchapter 25E Rights are available only with respect to shares of a registered
corporation held by a shareholder after the occurrence of a Control Transaction;
accordingly, Subchapter 25E Rights would not be available with respect to any
Shares tendered in the Offer and accepted for payment. The foregoing summary of
rights under

                                       33
<PAGE>   36

Subchapter 25E is qualified in its entirety by reference to the full text of
Subchapter 25E, which is attached hereto as Annex A.

     Subchapter 25F of the PBCL prohibits under certain circumstances certain
"business combinations," including mergers and sales or pledges of significant
assets, of a registered corporation with an "interested shareholder" for a
period of five years. Subchapter 25F exempts, among other things, business
combinations approved by the board of directors prior to a shareholder becoming
an interested shareholder and transactions with interested shareholders who
beneficially owned shares with at least 15% of the total voting power of a
corporation on March 23, 1988 and remain so. The Company has represented to the
Purchaser that Subchapter 25F is not applicable to the contemplated Merger.

     Subchapter 25G of the PBCL, relating to "control-share acquisitions,"
prevents under certain circumstances the owner of a control-share block of
shares of a registered corporation from voting such shares unless a majority of
both the "disinterested" shares and all voting shares approve such voting
rights. Failure to obtain such approval may result in a forced sale by the
control-share owner of the control-share block to the corporation at a possible
loss. The Company has opted out of Subchapter 25G in the By-laws and has
represented to the Purchaser that Subchapter 25G is not applicable to the
transactions contemplated by the Merger Agreement.

     Subchapter 25H of the PBCL, relating to disgorgement by certain controlling
shareholders of a registered corporation following attempts to acquire control,
provides that under certain circumstances any profit realized by a controlling
person from the disposition of shares of the corporation to any person
(including to the corporation under Subchapter 25G or otherwise) will be
recoverable by the corporation. The Company has opted out of Subchapter 25H in
the By-laws and has represented to the Purchaser that Subchapter 25H is not
applicable to the transactions contemplated by the Merger Agreement.

     Subchapter 25I of the PBCL entitles "eligible employees" of a registered
corporation to a lump sum payment of severance compensation under certain
circumstances if the employee is terminated, other than for willful misconduct,
within 90 days before voting rights lost as a result of a control-share
acquisition are restored by a vote of disinterested shareholders. Subchapter 25J
of the PBCL provides protection against termination or impairment under certain
circumstances of "covered labor contracts" of a registered corporation as a
result of a "business combination transaction" if the business operation to
which the covered labor contract relates was owned by the registered corporation
at the time voting rights are restored by shareholder vote after a control-share
acquisition. The Company has represented to Purchaser that Subchapters 25I and
25J are not applicable to the transactions contemplated by the Merger Agreement.

     Section 2504 of the PBCL provides that the applicability of Chapter 25 of
the PBCL to a registered corporation having a class or series of shares entitled
to vote generally in the election of directors registered under the Exchange Act
or otherwise satisfying the definition of a registered corporation under Section
2502(l) of the PBCL shall terminate immediately upon the termination of the
status of the corporation as a registered corporation. Purchaser intends to seek
to cause the Company to terminate the registration of the Shares under the
Exchange Act as soon after consummation of the Offer as the requirements for
termination of the registration of the Shares are met.

     Except for the filing pursuant to Section 8(a) of the PTDL described above,
neither Purchaser nor Parent has currently complied with any state takeover
statute or regulation; however Purchaser intends to comply with Subchapter 25E
of the PBCL to the extent it is applicable upon consummation of the Offer.
Purchaser reserves the right to challenge the applicability or validity of any
state law purportedly applicable to the Offer or the Merger and nothing in this
Offer to Purchase or any action taken in connection with the Offer or the Merger
is intended as a waiver of such right. If it is asserted that any state takeover
statute is applicable to the Offer or the Merger and an appropriate court does
not determine that it is inapplicable or invalid as applied to the Offer or the
Merger, Purchaser might be required to file certain information with, or to
receive approvals from, the relevant state authorities, and Purchaser might be
unable to accept for payment or pay for Shares tendered pursuant to the Offer,
or be delayed in consummating the Offer or the Merger. In such case, Purchaser
may not be obligated to accept for payment or pay for any Shares tendered
pursuant to the Offer.

     Antitrust.  The Offer and the Merger are subject to the HSR Act, which
provides that certain acquisition transactions may not be consummated unless
certain information has been furnished to the Antitrust Division of the
Department of Justice (the "DOJ") and the Federal Trade Commission (the "FTC")
and certain waiting period requirements have been satisfied.

     The waiting period under the HSR Act with respect to the Offer will expire
at 11:59 p.m., New York City time, on the fifteenth day after the date Parent's
form was filed unless early termination of the waiting period is granted.
However, the DOJ or the FTC may extend the waiting period by requesting
additional information or documentary material from Parent or the Company. If
such a request is made, such waiting period will expire at 11:59 p.m., New York
City time, on the tenth day after substantial compliance by Parent with such
request. Only one extension of the waiting period pursuant to a request for
additional information is authorized by the HSR Act. Thereafter, such waiting
period may be extended only by court order or with the consent of Parent. In
practice, complying with a request for additional information or material can
take a significant amount of time. In addition, if the DOJ or the FTC raises
substantive issues in connection with a proposed transaction, the parties
frequently engage in negotiations with the relevant governmental agency
concerning possible means of addressing those issues and may agree to delay
consummation of the transaction while such negotiations continue. The Purchaser
will not accept for payment Shares tendered pursuant to the Offer unless and
until the waiting period requirements imposed by the HSR Act with respect to the
Offer have been satisfied. See Section 14.

     The FTC and the DOJ frequently scrutinize the legality under the Antitrust
Laws of transactions such as Purchaser's acquisition of Shares pursuant to the
Offer and the Merger. At any time before or after Purchaser's acquisition of
Shares, the DOJ or the FTC could take such action under the Antitrust Laws as it
deems necessary or desirable in the public interest, including seeking to enjoin
the acquisition of Shares pursuant to the Offer or otherwise seeking divestiture
of Shares acquired by Purchaser or divestiture of substantial assets of Parent
or its subsidiaries. Private parties, as well as state governments, may also
bring legal action under the Antitrust Laws under certain circumstances. Based
upon an examination of information provided by the Company relating to the
businesses in which Parent and the Company are engaged, Parent and Purchaser
believe that the acquisition of Shares by Purchaser will not violate the
Antitrust Laws. Nevertheless, there can be no assurance that a challenge to the
Offer or other acquisition of Shares by Purchaser on antitrust grounds will not
be made or, if such a challenge is made, of the result. See Section 14 for
certain conditions to the Offer, including conditions with respect to litigation
and certain government actions.

     As used in this Offer to Purchase, "Antitrust Laws" shall mean and include
the Sherman Act, as amended, the Clayton Act, as amended, the HSR Act, the
Federal Trade Commission Act, as amended, and all other Federal and state
statutes, rules, regulations, orders, decrees, administrative and judicial
doctrines, and other laws that are designed or intended to prohibit, restrict or
regulate actions having the purpose or effect of monopolization or restraint of
trade.

16. FEES AND EXPENSES.

     TM Capital is serving as Dealer Manager in connection with the Offer and
has provided certain financial advisory services to Purchaser and Parent in
connection with the Offer and the Merger pursuant to an engagement letter, dated
March 3, 1999 (the "Engagement Letter") and a Dealer Manager Agreement, dated
July 15, 1999 (the "Dealer Manager Agreement"). Pursuant to the Engagement
Letter, Parent has agreed to pay a fee of approximately $525,000 for a tender
offer or merger between Parent and the Company be consummated, $100,000 of which
is payable upon the initiation of the Offer. Parent has also agreed to reimburse
TM Capital for its reasonable out-of-pocket expenses, including the legal fees
incurred in connection with its engagement; however, such expenses shall not
exceed $10,000 without prior notification of Parent. Parent has agreed to
indemnify TM Capital and certain related persons against certain liabilities and
expenses, including certain liabilities under the federal securities laws.

     Purchaser and Parent have retained DF King to serve as the Information
Agent and American Stock Transfer and Trust Company to serve as the Depositary
in connection with the Offer. The Information Agent

                                       35
<PAGE>   38

may contact holders of Shares by personal interview, mail, telephone, telex,
telegraph and other methods of electronic communication and may request brokers,
dealers, commercial banks, trust companies and other nominees to forward the
Offer materials to beneficial holders. The Information Agent and the Depositary
will each receive reasonable and customary compensation for their services, be
reimbursed for certain reasonable out-of-pocket expenses and be indemnified
against certain liabilities in connection with their services, including certain
liabilities and expenses under the federal securities laws.

     Except as set forth above, neither Parent nor Purchaser will pay any fees
or commissions to any broker or dealer or other person or entity in connection
with the solicitation of tenders of Shares pursuant to the Offer. Brokers,
dealers, banks and trust companies will be reimbursed by Purchaser for customary
mailing and handling expenses incurred by them in forwarding the Offer materials
to their customers.

17. MISCELLANEOUS.

     Purchaser is not aware of any state where the making of the Offer is
prohibited by administrative or judicial action pursuant to any valid state
statute. If Purchaser becomes aware of any valid state statute prohibiting the
making of the Offer or the acceptance of the Shares pursuant thereto, Purchaser
shall make a good faith effort to comply with such statute or seek to have such
statute declared inapplicable to the Offer. If, after such good faith effort,
Purchaser cannot comply with such state statute, the Offer will not be made to
(nor will tenders be accepted from or on behalf of) holders of Shares in such
state. In any jurisdiction the securities, blue sky or other laws of which
require the Offer to be made by a licenced broker or dealer, the Offer is being
made on behalf of the Purchaser by the Dealer Manager or one or more registered
brokers or dealers licenced under the laws of such jurisdiction.

     NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR TO MAKE ANY
REPRESENTATION ON BEHALF OF PARENT OR PURCHASER NOT CONTAINED HEREIN OR IN THE
LETTER OF TRANSMITTAL AND, IF GIVEN OR MADE, SUCH INFORMATION OR REPRESENTATION
MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED.

     Purchaser and Parent have filed with the Commission the Schedule 14D-1
pursuant to Rule 14d-3 under the Exchange Act, together with exhibits,
furnishing certain additional information with respect to the Offer. In
addition, the Company has filed with the Commission the Schedule 14D-9 pursuant
to Rule 14d-9 under the Exchange Act, setting forth its recommendation with
respect to the Offer and the reasons for its recommendation and furnishing
certain additional related information. Such Schedules and any amendments
thereto, including exhibits, should be available for inspection and copies
should be obtainable in the same manner set forth in Sections 8 and 9 of this
Offer to Purchase (except that such material will not be available at the
regional offices of the Commission).

corporation which on June 21, 1988, did not have outstanding one or more classes
or series of preference shares entitled, upon the occurrence of a default in the
payment of dividends or another similar contingency, to elect a majority of the
members of the board of directors (a bylaw adopted on or before June 21, 1988,
by a corporation excluded from the scope of this paragraph by the restriction of

section. See section 101(c) (relating to references to prior statutes).

     holders thereof to cast in excess of 50% of the votes that all shareholders
     would be entitled to cast in the election of directors of such subsidiary,

     meaning of this subchapter.

          "Voting shares."  The term shall have the meaning specified in section
     2552 (relating to definitions).

     2543 CONTROLLING PERSON OR GROUP. -- (a) General rule. -- For the purpose
of this subchapter, a "controlling person or group" means a person who has, or a
group of persons acting in concert that has, voting power over voting shares of
the registered corporation that would entitle the holders thereof to cast at
least 20% of the votes that all shareholders would be entitled to cast in an
election of directors of the corporation.

     (b) Exceptions generally. -- Notwithstanding subsection (a): (1) A person
or group which would otherwise be a controlling person or group within the
meaning of this section shall not be deemed a controlling person or group
unless, subsequent to the later of March 23, 1988, or the date this subchapter
becomes applicable to a corporation by bylaw or article amendment or otherwise,
that person or group increases the percentage of outstanding voting shares of
the corporation over which it has voting power to in excess of the percentage of
outstanding voting shares of the corporation over which that person or group had
voting power on such later date, and to at least the amount specified in
subsection (a), as the result of forming or enlarging a group or acquiring, by
purchase, voting power over voting shares of the corporation. (2) No person or
group shall be deemed to be a controlling person or group at any particular time

been held continuously by a natural person since January 1, 1983, and which are
held by such natural person at such time. (ii) Shares which are held at such
time by any natural person or trust, estate, foundation or other similar entity
to the extent the shares were acquired solely by gift, inheritance, bequest,
devise or other testamentary distribution or series of these transactions,
directly or indirectly, from a natural person who had acquired the shares prior
to January 1, 1983. (iii) Shares which were acquired pursuant to a stock split,
stock dividend, reclassification or similar recapitalization with respect to
shares described under this paragraph that have been held continuously since
their issuance by the corporation by the natural person or entity that acquired
them from the corporation or that were acquired, directly or indirectly, from
such natural person or entity, solely pursuant to a transaction or series of
transactions described in subparagraph (ii), and that are held at such time by a
natural person or entity described in subparagraph (ii). (iv) Control shares as

shares acquired in a control-share acquisition). (v) Shares, the voting rights
of which are attributable to a person under subsection (d) if: (A) the person

arrangement or understanding or has the relationship directly with the

effectively possess the voting rights of the shares. (vi) Shares acquired
directly from the corporation or an affiliate or associate, as defined in
section 2552 (relating to definitions), of the corporation by a person engaged
in business as an underwriter of securities who acquires the shares through his
participation in good faith in a firm commitment underwriting registered under
the Securities Act of 1933. (3) In determining whether a person or group is or
would be a controlling person or group at any particular time, there shall be
disregarded voting power arising from a contingent right of the holders of one
or more classes or series of preference shares to elect one or more members of
the board of directors upon or during the continuation of a default in the
payment of dividends on such shares or another similar contingency.

     (c) Certain record holders. -- A person shall not be a controlling person

person or group under subsection (b).

     (d) Existence of voting power. -- For the purposes of this subchapter, a

share.

corporation or an equivalent request for transfer of uncertificated securities.

     (b) Obligations of the corporation. -- If the controlling person or group

and stating that value. (3) If the shareholder believes the fair value of his
shares is higher, that this subchapter provides an appraisal procedure for
determining the fair value of such shares, specifying the name of the court and

subchapter.

     (d) Optional procedure. -- The controlling person or group may, at its
option, supply with the notice referenced in subsection (c) a form for the
shareholder to demand payment of the partial payment amount directly from the

payment demand must be sent and the procedures to be followed.

controlling person or group for payment of the amount provided in subsection (c)
with respect to the voting shares of the corporation held by the shareholder,

equal to the fair value of each voting share as of the date on which the control
transaction occurs, taking into account all relevant factors, including an
increment representing a proportion of any value payable for acquisition of
control of the corporation.

     (d) Purchases independent of subchapter. -- The provisions of this
subchapter shall not preclude a controlling person or group subject to this
subchapter from offering, whether in the notice required by section
                                       A-3
<PAGE>   46

2545 or otherwise, to purchase voting shares of the corporation at a price other
than that provided in subsection (c), and the provisions of this subchapter
shall not preclude any shareholder from agreeing to sell his voting shares at
that or any other price to any person.

     2547 VALUATION PROCEDURES. -- (a) General rule. -- If, within 45 days (or
such other time period, if any, as required by applicable law) after the date of
the notice required by section 2545 (relating to notice to shareholders), or, if
such notice was not provided prior to the date of the written demand by the
shareholder under section 2546 (relating to shareholder demand for fair value),
then within 45 days (or such other time period, if any, required by applicable
law) of the date of such written demand, the controlling person or group and the
shareholder are unable to agree on the fair value of the shares or on a binding
procedure to determine the fair value of the shares, then each shareholder who
is unable to agree on both the fair value and on such a procedure with the
controlling person or group and who so desires to obtain the rights and remedies
provided in this subchapter shall, no later than 30 days after the expiration of
the applicable 45-day or other period, surrender to the court certificates
representing any of the shares that are certificated shares, duly endorsed for
transfer to the controlling person or group, or cause any uncertificated shares
to be transferred to the court as escrow agent under subsection (c) with a
notice stating that the certificates or uncertificated shares are being
surrendered or transferred, as the case may be, in connection with the petition
referenced in section 2545 or, if no petition has theretofore been filed, the
shareholder may file a petition within the 30-day period in the court praying
that the fair value (as defined in this subchapter) of the shares be determined.

     (b) Effect of failure to give notice and surrender certificates. -- Any
shareholder who does not so give notice and surrender any certificates or cause
uncertificated shares to be transferred within such time period shall have no
further right to receive, with respect to shares the certificates of which were
not so surrendered or the uncertificated shares which were not so transferred
under this section, payment under this subchapter from the controlling person or
group with respect to the control transaction giving rise to the rights of the
shareholder under this subchapter.

     (c) Escrow and notice. -- The court shall hold the certificates surrendered
and the uncertificated shares transferred to it in escrow for, and shall
promptly, following the expiration of the time period during which the
certificates may be surrendered and the uncertificated shares transferred,

surrendered or transferred.

then make a partial payment for the shares so surrendered or transferred to the
court, within ten business days of receipt of the notice from the court, at a
per-share price equal to the partial payment amount. The court shall then make
payment as soon as practicable, but in any event within ten business days, to
the shareholders who so surrender or transfer their shares to the court of the
appropriate per-share amount received from the controlling person or group.

     (e) Appointment of appraiser. -- Upon receipt of any share certificate
surrendered or uncertificated share transferred under this section, the court

appraiser with experience in appraising share values of companies of like nature
to the registered corporation to determine the fair value of the shares.

     (f) Appraisal procedure. -- The appraiser so appointed by the court shall,
as soon as reasonably practicable, determine the fair value of the shares
subject to its appraisal and the appropriate market rate of interest on the
amount then owed by the controlling person or group to the holders of the
shares. The determination of any appraiser so appointed by the court shall be
final and binding on both the controlling person or group and all shareholders
who so surrendered their share certificates or transferred their shares to the
court, except that the determination of the appraiser shall be subject to review
to the extent and within the time provided or prescribed by law in the case of
other appointed judicial officers. See 42 Pa.C.S. Sections 5105(a)(3) (relating
to right to appellate review) and 5571(b) (relating to appeals generally).

     (g) Supplemental payment. -- Any amount owed, together with interest, as
determined pursuant to the appraisal procedures of this section shall be payable
by the controlling person or group after it is so determined and upon and

surrendered or the uncertificated shares transferred to it to

                                       A-4

the controlling person or group as soon as practicable but in any event within
ten business days after the final determination of the amount owed) of the
certificate or certificates representing shares surrendered or the
uncertificated shares transferred to the court, and the court shall then make

per-share amount received from the controlling person or group.

     (h) Voting and dividend rights during appraisal proceedings. --
Shareholders who surrender their shares to the court pursuant to this section
shall retain the right to vote their shares and receive dividends or other
distributions thereon until the court receives payment in full for each of the
shares so surrendered or transferred of the partial payment amount (and,
thereafter, the controlling person or group shall be entitled to vote such
shares and receive dividends or other distributions thereon). The fair value (as
determined by the appraiser) of any dividends or other distributions so received
by the shareholders shall be subtracted from any amount owing to such
shareholders under this section.

     (i) Powers of the court. -- The court may appoint such agents, including
the transfer agent of the corporation, or any other institution, to hold the

as the court determines are appropriate to effect the purposes of this
subchapter.

     (j) Costs and expenses. -- The costs and expenses of any appraiser or other
agents appointed by the court shall be assessed against the controlling person
or group. The costs and expenses of any other procedure to determine fair value
shall be paid as agreed to by the parties agreeing to the procedure.

subchapter is plenary and exclusive and the controlling person or group and all
shareholders who so surrendered or transferred their shares to the court shall
be made a party to the proceeding as in an action against their shares.

     (l) Duty of corporation. -- The corporation shall comply with requests for
information, which may be submitted pursuant to procedures maintaining the
confidentiality of the information, made by the court or the appraiser selected
by the court. If any of the shares of the corporation are not represented by
certificates, the transfer, escrow or retransfer of those shares contemplated by
this section shall be registered by the corporation, which shall give the
written notice required by section 1528(f) (relating to uncertificated shares)
to the transferring shareholder, the court and the controlling shareholder or
group, as appropriate in the circumstances.

     (m) Payment under optional procedure. -- Any amount agreed upon between the
parties or determined pursuant to the procedure agreed upon between the parties

determined and upon and concurrently with the delivery of any certificate or
certificates representing such shares or the transfer of any uncertificated
shares to the controlling person or group by the shareholder.

     (n) Title to shares. -- Upon full payment by the controlling person or
group of the amount owed to the shareholder or to the court, as appropriate, the
shareholder shall cease to have any interest in the shares.

person or group that proposes to engage in a control transaction may comply with

July 15, 1999

Dear Trion, Inc. Stockholder:

     I am pleased to inform you that on July 12, 1999, Trion, Inc. (the
"Company") entered into an Agreement and Plan of Merger providing for the
acquisition by TI Acquisition Corp. (the "Purchaser"), a wholly owned subsidiary
of Fedders Corporation (the "Parent"), of the Company.

     As required by the Agreement and Plan of Merger, the Purchaser has
commenced a cash tender offer (the "Offer") to purchase all outstanding shares
of the Company's Common Stock (the "Shares") at a price of $5.50 net per share
payable in cash at the closing. The Offer is conditioned upon, among other
things, satisfaction of the condition that there be validly tendered and not
withdrawn prior to the expiration of the Offer, a number of Shares, when added
to any Shares owned by Parent or Purchaser, that represents at least eighty
percent (80%) of the Shares outstanding, on a fully diluted basis of the
Company. Following the purchase of Shares under the Offer and the satisfaction
of certain other conditions, Purchaser will merge with and into the Company (the
"Merger") and each Share not purchased in the Offer (other than dissenting
Shares and Shares owned by Purchaser, the Company, Parent, or any wholly owned
subsidiary of the Parent) will be converted into the right to receive $5.50 in
cash or such higher price per share as may be paid pursuant to the Offer,
without interest.

     THE BOARD OF DIRECTORS OF THE COMPANY HAS BY THE UNANIMOUS VOTE OF ALL
DIRECTORS PRESENT APPROVED THE OFFER AND THE MERGER, HAS DETERMINED THAT THE
OFFER AND THE MERGER ARE FAIR TO AND IN THE BEST INTERESTS OF THE STOCKHOLDERS
OF THE COMPANY AND RECOMMENDS ACCEPTANCE OF THE OFFER BY THE STOCKHOLDERS OF THE
COMPANY.

     Over the past few months, the Board of Directors of the Company has been
exploring strategic alternatives to improve stockholder value. The Board of
Directors of the Company believes the Offer and the Merger accomplish these
objectives. The Board of Directors believes the price to be paid by Purchaser
for the Company is fair.

     In arriving at its recommendation, the Board of Directors has given careful
consideration to a number of factors as described in the enclosed Schedule 14D-9
filed with the Securities and Exchange Commission, including the opinion of
Harris Williams & Co., the Company's financial advisor ("Harris Williams"), that
as of the date of the opinion, the consideration to be received by the holders
of Shares in the Offer and the Merger is fair from a financial point of view to
such holders. The Schedule 14D-9 contains other important information relating
to the Offer, and you are encouraged to read the Schedule 14D-9 carefully.

     Accompanying this letter and Schedule 14D-9 are (i) an Information
Statement, which is attached as Annex I to the Schedule 14D-9, (ii) the fairness
opinion of Harris Williams, which is attached hereto as Annex II to the Schedule
14D-9, and (iii) the Purchaser's Offer to Purchase, dated July 15, 1999,
together with related materials, including the Letter of Transmittal to be used
for tendering Shares. These documents set forth the terms and conditions of the
Offer and provide instructions as to how to tender Shares. These documents
describe the reasons for the Board of Directors recommendation and certain other
factors that stockholders should consider. We urge you to read the enclosed
materials carefully.

     On behalf of the Board of Directors and management of the Company, we thank
you for your support.

                                          Sincerely,

The Board of Directors
Trion, Inc.

Gentlemen:

     You have requested our opinion as to the fairness, from a financial point
of view, to the holders (the "Shareholders") of the Common Stock, par value
$0.50 per share (the "Shares") of Trion, Inc. ("Trion" or the "Company") of the
Consideration (as defined herein) to be received pursuant to the terms and
subject to the conditions set forth in the Agreement and Plan of Merger, dated
as of July 12, 1999 (the "Agreement"), by and between Trion, Fedders Corporation
("Fedders"), and an indirect wholly-owned subsidiary of Fedders ("Acquisition").
Pursuant to the Agreement, Acquisition will commence a tender offer (the
"Offer") to purchase any and all of the outstanding Shares at a price of $5.50
per Share in cash. Following consummation of the Offer and subject to certain
closing conditions, Acquisition will be merged with and into the Company (the
"Merger") and each outstanding Share (other than Shares owned by the Company,
Fedders, or Acquisition) will be converted into the right to receive $5.50 per
Share in cash. The cash consideration to be paid pursuant to the Offer and the
Merger is referred to herein as the "Consideration."

     In the course of our analyses for rendering this opinion, we have:

     1. reviewed the Agreement;

     2. held discussions with certain senior officers, directors, and other
        representatives and advisors of Trion and certain senior officers and
        other representatives and advisors of Fedders concerning the business,
        operations, and prospects of Trion and Fedders;

     3. examined certain publicly available business and financial information
        relating to Trion and Fedders, including the respective companies'
        historical and projected earnings, capitalization, and financial
        condition, as well as certain financial forecasts and other data for
        Trion which were provided to us by the management of Trion;

     4. analyzed certain financial, stock market, and other publicly available
        information relating to the businesses of other companies whose
        operations we considered generally comparable to Trion;

     5. considered, to the extent publicly available, the financial terms of
        certain other recent mergers and acquisitions which we considered
        generally comparable to the Offer and the Merger and otherwise relevant
        to our inquiry;

     6. reviewed the current and historical market prices and trading volumes of
        Trion Common Stock;

     7. considered such other financial, economic, and market criteria and
        conducted such other analyses and examinations as we deemed necessary to
        arrive at our opinion.

     In rendering our opinion, we have assumed and relied, without independent
verification, upon the accuracy and completeness of all financial and other
information publicly available or furnished to or otherwise discussed with us.
With respect to financial forecasts and other information provided to or
otherwise discussed with us, we have assumed, with your consent, that such
forecasts and other information were reasonably prepared on bases reflecting the
best currently available estimates and judgements as to the expected future
financial performance of Trion. We have not made or been provided with an
independent evaluation or appraisal of the assets or liabilities (contingent or
otherwise) of Trion, nor have we made any physical inspection of the properties
or assets of Trion. We have not been asked to consider, and our opinion does not
address, the relative merits of the Offer and the Merger as compared to any
alternative business strategies or alternative prospective purchasers and their
potential proposals that might exist for Trion. Our
<PAGE>   2

opinion is necessarily based upon financial, stock market, economic, and other
conditions and circumstances existing and disclosed to us as of the date hereof.
We have relied as to all legal matters on advice of counsel to the Company.

     Harris Williams & Co. has been engaged to explore strategic alternatives
for Trion including a potential sale of the Company to interested third parties.
For these and other advisory services provided to the Board of Directors of the
Company and to Trion in connection with the Offer and the Merger, Harris
Williams & Co. will receive a fee contingent upon the consummation of the Offer
and the Merger in addition to a retainer fee which is being paid prior to the
transaction and will be credited towards the contingency fee. In addition, the
Company has agreed to indemnify us for certain liabilities that may arise out of
the rendering of this opinion.

     Our advisory services and the opinion expressed herein are provided only
for the use of the Board of Directors of Trion in its evaluation of the proposed
Merger. Our opinion is not intended to be and does not constitute a
recommendation to any Shareholder as to how such Shareholder should respond to
the Offer or vote at any Shareholders' meeting which might be held in connection
with the Merger. It is understood that this letter may be included in its
entirety in a Schedule 14D-9 relating to the Offer or a proxy statement relating
to the Merger or as may otherwise be required by law or by a court of competent
jurisdiction.

     Based upon and subject to the foregoing and based upon such other matters
as we consider relevant, our experience as investment bankers, the process that
was undertaken by us to identify strategic alternatives for the Company, and our
work as described above, we are of the opinion that, as of the date hereof, the
value of the Consideration is fair, from a financial point of view, to the
holders of the Shares.

Very truly yours,

[harris williams sig]

FEDDERS TO ACQUIRE TRION, INC.

Liberty Corner, NJ and Sanford, NC - July 13, 1999 - Fedders Corporation (NYSE:
FJA & FJC), a global air conditioning company, and Trion, Inc. (NASDAQ: TRON), a
world leader in the indoor air quality industry, jointly announced today that
they entered into a definitive agreement providing for Fedders' acquisition of
Trion at a price of $5.50 per share in cash for all outstanding shares of
Trion's common stock. The Agreement has been approved by the Boards of Directors
of both Trion and Fedders. Under the Agreement, a newly-formed wholly-owned
subsidiary of Fedders will commence a cash tender offer to purchase all of the
outstanding shares of Trion for $5.50 per share. Trion has approximately 7.2
million shares of common stock outstanding.

The tender offer will commence as soon as practicable, but not later than July
19, 1999, and is expected to close in August 1999. The tender offer is
conditioned upon the tender of 80.0% of the shares of Trion common stock
outstanding on a fully diluted basis, certain regulatory filings and other
customary conditions. The Agreement also provides for the merger of a
wholly-owned subsidiary of Fedders into Trion following the tender offer.
Following the merger Trion will continue its business as a wholly-owned
subsidiary of Fedders.

Each of Trion's directors, who collectively own 10.1% of Trion's outstanding
common stock, has entered into a definitive agreement with Fedders pursuant to
which each director has agreed, among other things, to tender his shares
pursuant to the cash tender offer and to grant to Fedders an option to purchase
such shares at a purchase price of $5.50 per share, exercisable upon the
occurrence of certain events.

In addition, Trion and Fedders have entered into a stock option agreement
pursuant to which Trion has granted to Fedders an irrevocable option to purchase
up to 19.9% of Trion's outstanding common stock at a purchase price of $5.50 per
share, exercisable upon the occurrence of certain events.

Trion manufactures and sells a broad line of high-performance products that
improve indoor air quality in cleanrooms, industrial/commercial and residential
environments. Their extensive line of products includes electronic air cleaners,
HEPA & ULPA filters, humidifiers and dust collectors. Trion's sales were $57.2
million in 1998.

The indoor air quality industry is estimated to exceed $3.0 billion. Consistent,
long-term industry growth is expected. As governments tighten regulations
regarding levels of emissions released into the workplace and environment, and
as air pollution continues
<PAGE>   2
to be a significant health issue, the global demand for indoor air quality
products is expected to increase.

Commenting on the acquisition, Fedders Chief Executive Officer, Sal Giordano,
Jr., said "Fedders' acquisition of Trion is strategically important to the
growth of both companies. Trion's line of indoor air quality products is
complementary to Fedders' existing product line of air conditioners and
dehumidifiers. Many of the products, including air cleaners and humidifiers, are
counter-seasonal to air conditioner and dehumidifier sales. Trion's presence in
England will strengthen Fedders' position in Europe, while Fedders' presence in
Asia, where it has its international headquarters in Singapore and a
manufacturing facility in Ningbo, China, will enable Trion to grow there."
Steven L. Schneider, President and Chief Executive Officer of Trion, said "The
Trion team is looking forward to becoming an important part of Fedders. We
expect Fedders' extensive experience with Big Box retailers to help grow our
household air cleaner business and we anticipate deriving significant benefits
from their global sourcing capabilities for all of our products."

TM Capital Corp. served as financial advisor to Fedders Corporation in
connection with this transaction and Harris Williams & Co. served as financial
advisor to Trion, Inc.
