     THIS AGREEMENT AND PLAN OF MERGER, dated as of April 21, 1998 (this
"Agreement"), is by and among GEC Incorporated, a Delaware corporation
("Parent"), GEC Acquisition Corp., a Delaware corporation and a wholly owned
subsidiary of Parent ("Purchaser"), and Tracor, Inc., a Delaware corporation
("the Company").  Parent and Purchaser are sometimes referred to herein as the
"Parent Companies."

                                    RECITALS:

     The respective Boards of Directors of the Company, Parent, and Purchaser
have approved the acquisition of the Company by Parent on the terms and subject
to the conditions set forth in this Agreement.

     In furtherance of such acquisition, Parent proposes to cause Purchaser to
make a tender offer (as it may be amended from time to time as permitted under
this Agreement, the "Offer") to purchase all the issued and outstanding shares
of common stock, par value $0.01 per share, of the Company ("Company Common
Stock"), including the associated Company Rights, at a price per share of
Company Common Stock (including the associated Company Right) of $40.00, net to
the seller in cash, upon the terms and subject to the conditions set forth in
this Agreement.

     Upon the terms and subject to the conditions of this Agreement and in
accordance with the GCL, Purchaser will merge with and into the Company and the
Company will be the Surviving Corporation.

     Simultaneously with the execution and delivery of this Agreement, Parent
and Purchaser, on the one hand, and each member of the Board of Directors of
the Company and certain members of management on the other hand ("Certain
Stockholders"), are entering into an agreement (the "Stockholders Agreement")
pursuant to which Certain Stockholders have agreed to take specified actions in
furtherance of the transactions contemplated by this Agreement.

     NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth in this
Agreement, the parties hereto agree as follows:

Agreement to a Section, such reference shall be to a Section of this Agreement

                                    ARTICLE II

                                     THE OFFER

     SECTION 2.1  The Offer.

     (a)  Subject to the conditions of this Agreement, as promptly as
practicable but in no event later than five Business Days after the date of
this Agreement, Purchaser shall, and Parent shall cause Purchaser to, commence
the Offer within the meaning of the applicable Regulations of the SEC.  The
obligation of Purchaser to, and of Parent to cause Purchaser to, commence the
Offer or accept for payment, or pay for, any shares of Company Common Stock
tendered pursuant to the Offer shall be subject to the conditions set forth in
Annex B (any of which may be waived by Purchaser in its sole discretion,
provided that, without the consent of the Company, Purchaser may not waive the
Minimum Tender Condition or the condition set forth in paragraph (b)(viii) of
Annex B) and to the other provisions of this Agreement.  The initial expiration
date of the Offer shall be the 20th Business Day following the commencement of
the Offer (determined using Rule 14d-1(c)(6) under the Exchange Act). 
Purchaser expressly reserves the right to modify the terms of the Offer, except
that, without the consent of the Company, Purchaser shall not (i) reduce the
number of shares of Company Common Stock subject to the Offer, (ii) reduce the
price per share of Company Common Stock to be paid pursuant to the Offer,
(iii) modify or add to the conditions set forth in Annex B in any manner
materially adverse to the holders of shares of Company Common Stock,
(iv) except as provided in the next sentence, extend the Offer, (v) change the
form of consideration payable in the Offer or (vi) otherwise amend the Offer in
any manner materially adverse to the holders of shares of Company Common Stock.
Notwithstanding the foregoing, Purchaser may, without the consent of the
Company, (i) extend the Offer, if at the scheduled expiration date of the Offer
any of the conditions to Purchaser's obligation to purchase shares of Company
Common Stock are not satisfied, until such time as such conditions are
satisfied or waived, (ii) extend the Offer for a period of not more than 10
Business Days beyond the expiration date that would otherwise be permitted
under clause (i) of this sentence, if on the date of such extension less than
90% of the Fully Diluted Shares have been validly tendered and not properly
withdrawn pursuant to the Offer, (iii) extend the Offer for any period required
by any Regulation, interpretation or position of the SEC or the staff thereof
applicable to the Offer and (iv) extend the Offer for any reason for a period
of not more than 10 Business Days beyond the latest expiration date that would
otherwise be permitted under clause (i), (ii) or (iii) of this sentence.  On
the terms and subject to the conditions of the Offer and this Agreement,
Purchaser shall, and Parent shall cause Purchaser to, pay for all shares of
Company Common Stock validly tendered and not withdrawn pursuant to
the Offer that Purchaser becomes obligated to purchase pursuant to the Offer as
soon as practicable after the expiration of the Offer.

     (b)  Notwithstanding anything to the contrary contained in this Agreement,
Parent and Purchaser shall not be required to commence the Offer in any
jurisdiction other than the United States of America.  

     (c)  On the date of the commencement of the Offer, Purchaser shall file
with the SEC a Tender Offer Statement on Schedule 14D-1 with respect to the
Offer ("Schedule 14D-1") which will contain an offer to purchase and form of
the related letter of transmittal (the Schedule 14D-1 and the documents
included therein pursuant to which the Offer will be made, together with any
supplements or amendments thereto, collectively, the "Offer Documents"). 
Parent, Purchaser, and the Company each agrees promptly to correct any
information provided by it for use in the Offer Documents if and to the extent
that it shall have become false or misleading in any material respect and
Parent and Purchaser further agree to take all steps necessary to cause the
Offer Documents as so corrected to be filed with the SEC and be disseminated to
holders of shares of Company Common Stock, in each case, as and to the extent
required by applicable federal securities Laws.  Parent and Purchaser agree to
give the Company and its counsel a reasonable opportunity to review and comment
on the Offer Documents prior to the filing of the Offer Documents with the SEC.
Purchaser agrees to provide the Company and its counsel in writing with any
comments Purchaser and its counsel may receive from the SEC or its staff with
respect to the Offer Documents promptly after the receipt thereof.

     SECTION 2.2  Company Actions. The Company hereby consents to the Offer and
represents that its Board of Directors (at a meeting duly called and held) has
unanimously (a) determined that the Offer and the Merger are fair to the
stockholders of the Company and are in the best interests of the stockholders
of the Company, (b) approved this Agreement, the Offer, the Merger and the
Stockholders Agreement, including for purposes of Section 203 of the GCL, and
(c) resolved to recommend acceptance of the Offer and approval and adoption of
this Agreement and the Merger by the stockholders of the Company which approval
constitutes approval of each of the transactions contemplated by this Agreement
for purposes of the applicable provisions of the GCL.  The Financial Advisor
has delivered to the Board of Directors of the Company its opinion that the
consideration to be received by the holders of shares of Company Common Stock
in the Offer and the Merger is fair to the holders of shares of Company Common
Stock from a financial point of view.  The Company hereby agrees to file a
Solicitation/Recommendation Statement on Schedule 14D-9 (together with any
amendments or supplements thereto, the "Schedule 14D-9") containing such
recommendation with the SEC (and the information required by Section 14(f) of
the Exchange Act if Parent shall have furnished such information to the Company
in a timely manner) and to mail such Schedule 14D-9 to the stockholders of the
Company; provided, that such recommendation may be withdrawn, modified or
amended by the Company's Board of Directors only to the extent permitted by
Section 7.3(b).  Such Schedule 14D-9 shall be filed on the same date as
Purchaser's Schedule 14D-1 is filed and mailed together with the Offer
Documents.  Each of the Company, Parent, and Purchaser agrees promptly to
correct any information provided by it for use in the Schedule 14D-9 if and to
the extent that it shall have become false or misleading in any material
respect, and the Company further agrees to take all steps necessary to cause
the Schedule 14D-9 as so corrected to be filed with the SEC and disseminated to
the holders of shares of Company Common Stock, in each case, as and to the
extent required by applicable federal securities Laws.  The Company agrees to
give Purchaser and its counsel a reasonable opportunity to review and comment
on the Schedule 14D-9 prior to the Company's filing of the Schedule 14D-9 with
the SEC. The Company agrees to provide Purchaser and its counsel in writing
with any comments the Company or its counsel may receive from the SEC or its
staff with respect to the Schedule 14D-9 promptly after the receipt thereof.

     SECTION 2.3  Stockholder Lists.  In connection with the Offer, the Company
will promptly furnish Purchaser with mailing labels, security position listings
and any available listing or computer file containing the names and addresses
of the record holders of shares of Company Common Stock as of a recent date and
of those Persons becoming record holders subsequent to such date (to the extent
available), together with all other information in the Company's possession or
control regarding the beneficial owners of shares of Company Common Stock and
shall furnish Purchaser with such information and assistance (including, to the
extent available, updated lists of stockholders, security position listings and
computer files) as Purchaser or its agents may reasonably request in
communicating the Offer to the record and beneficial holders of shares of
Company Common Stock.

     SECTION 2.4  Composition of the Board of Directors; Section 14(f).

     Promptly upon the acceptance for payment of, and payment by Purchaser for,
any shares of Company Common Stock pursuant to the Offer, Purchaser shall be
entitled to designate such number of directors on the Board of Directors of the
Company as will give Purchaser, subject to compliance with Section 14(f) of the
Exchange Act, representation on the Board of Directors of the Company equal to
at least that number of directors, rounded up to the next whole number, which
is the product of (a) the total number of directors on the Company's Board of
Directors (giving effect to the directors elected pursuant to this sentence)
multiplied by (b) the percentage that (i) such number of shares of Company
Common Stock so accepted for payment and paid for by Purchaser plus the number
of shares of Company Common Stock otherwise owned by Purchaser or any other
Subsidiary of Parent bears to (ii) the number of such shares outstanding, and
the Company shall, at such time, cause Purchaser's designees to be so elected;
provided, however, that in the event that Purchaser's designees are appointed
or elected to the Board of Directors of the Company, until the Effective Time
the Board of the Directors of the Company shall have at least three directors
who are directors on the date of this Agreement (the "Independent Directors");
and provided further that, in such event, if the number of Independent
Directors shall be reduced below three for any reason whatsoever, any remaining
Independent Directors (or Independent Director, if there shall be only one
remaining) shall be entitled to designate persons to fill such vacancies who
shall be deemed to be Independent Directors for purposes of this Agreement or,
if no Independent Directors then remain, the other directors promptly shall
designate three persons to fill such vacancies who shall not be officers,
stockholders or Affiliates of Parent or Purchaser, and such persons shall be
deemed to be Independent Directors for purposes of this Agreement.  Subject to
applicable Law, the Company shall take all action requested by Parent necessary
to effect any such election, including mailing to its stockholders the
information statement required under Rule 14f-1 containing the information
required by Section 14(f) of the Exchange Act and Rule 14f-1 promulgated
thereunder, and the Company shall make such mailing with the mailing of the
Schedule 14D-9 (provided that Purchaser shall have provided to the Company on a
timely basis all information required to be included in the information
statement required under Rule 14f-1 with respect to Purchaser's designees). 
Purchaser's designees shall be divided between the classes of directors as
necessary to comply with the requirements of the Company's bylaws.  In
connection with the foregoing, the Company shall promptly, at the option of
Purchaser, either increase the size of the Board of Directors of the Company or
obtain the resignation of such number of its current directors as is necessary
to enable Purchaser's designees to be elected or appointed to the Board of
Directors of the Company as provided above.  The date on which Purchaser's
designees constitute a majority of the Company's Board of Directors is herein
referred to as the "Control Date."

                                   ARTICLE III

                                    THE MERGER

     SECTION 3.1  The Merger.  Subject to the terms and conditions and in
reliance upon the representations, warranties, covenants and agreements
contained herein, Purchaser shall merge with and into the Company at the
Effective Time (the "Merger").  The terms and conditions of the Merger and the
mode of carrying the same into effect shall be as set forth in this Agreement.
As a result of the Merger, the separate corporate existence of Purchaser shall
cease and the Company shall continue as the Surviving Corporation.  At the
election of Parent, any direct or indirect wholly owned Subsidiary of Parent
may be substituted for Purchaser as a constituent corporation in the Merger;
provided that any such substitution could not reasonably be expected to
materially and adversely affect the ability of the parties to perform their
obligations hereunder, or materially delay the consummation of the Offer or the
Merger.  In such event, the parties shall execute an appropriate amendment to
this Agreement in order to reflect the foregoing.

     SECTION 3.2  Effective Time.  As soon as practicable after the
satisfaction or, if permissible, waiver of the conditions set forth in
Article VIII, the parties hereto shall cause the Merger to be consummated by
filing a certificate of merger (the "Certificate of Merger") with the Secretary
of State of the State of Delaware, in such form as required by, and executed in
accordance with the relevant provisions of, the GCL.

     SECTION 3.3  Effect of the Merger.  At the Effective Time, the effect of
the Merger shall be as provided in the applicable provisions of the GCL. 
Without limiting the generality of the foregoing, and subject thereto, at the
Effective Time, except as otherwise provided herein, all the property, rights,
privileges, powers and franchises of Purchaser and the Company shall vest in
the Surviving Corporation, and all debts, liabilities and duties of Purchaser
and the Company shall become the debts, liabilities and duties of the Surviving
Corporation.

     SECTION 3.4  Certificate of Incorporation; Bylaws.  (a)  The certificate
of incorporation of the Company, as in effect immediately prior to the
Effective Time, shall be amended at the Effective Time so that Article IV,
Section 1 of such certificate of incorporation reads in its entirety as
follows:  "The total number of shares of all classes of stock which the
corporation shall have authority to issue is 1,000 shares of Common Stock, par
value $1.00 per share ("Common Stock")." and, as so amended, such certificate
of incorporation shall be the certificate of incorporation of the Surviving
Corporation until thereafter changed or amended as provided therein or by
applicable Law.

     (b)  The bylaws of Purchaser as in effect immediately prior to the
Effective Time shall be the bylaws of the Surviving Corporation until
thereafter changed or amended as provided therein or by applicable Law;
provided, however, that the bylaws of Purchaser shall be amended prior to the
Effective Time to the extent necessary to comply with Purchaser's obligations
under the first sentence of Section 7.13(a). 

     SECTION 3.5  Directors and Officers.  The directors of Purchaser
immediately prior to the Effective Time shall be the directors of the Surviving
Corporation, each to hold office in accordance with the certificate of
incorporation and bylaws of the Surviving Corporation, and the officers of the
Company immediately prior to the Effective Time shall be the officers of the
Surviving Corporation, in each case until the earlier of their resignation or
removal or until their respective successors are duly elected or appointed and
qualify.

     SECTION 3.6  Stock Options and Warrants.

     (a)  Upon consummation of the Merger, all then outstanding Company Stock
Options and all Company Common Stock subject to a vesting requirement granted
to any Company employee or director ("Restricted Stock") shall be canceled in
exchange for a cash payment to the holder of a Company Stock Option or
Restricted Stock award equal to (i) in the case of Company Stock Options, A
times B, where A equals the difference between the Per Share Merger
Consideration and the per share exercise price of the holder's Company Stock
Option and B equals the number of shares of Company Common Stock subject to the
holder's Company Stock Option and (ii) in the case of Restricted Stock, the
number of shares of the holder's Restricted Stock times the Per Share Merger
Consideration. All applicable Taxes shall be withheld from any proceeds payable
under this Section 3.6(a).

     (b)  Before the commencement of the Offer, the Company shall take all
actions (including obtaining any and all consents from employees or directors)
necessary to implement Section 3.6(a); provided, the Company may not provide
additional compensation, benefits or other payments to holders of Company Stock
Options or Restricted Stock as an inducement to consent to the provisions of
Section 3.6(a).

     (c)  Except as provided herein or as otherwise agreed to by the parties,
(i) the Company Option Plans shall terminate as of the Effective Time and the
provisions in any other plan, program or arrangement providing for the issuance
or grant by the Company or any of its Subsidiaries of any interest in respect
of the capital stock of the Company or any of its Subsidiaries shall be
terminated as of the Effective Time, and (ii) following the Effective Time no
holder of Company Stock Options or Restricted Stock or any participant in the
Company Option Plans or any other such plans, programs or arrangements shall
have any right thereunder to acquire any equity securities of the Company, the
Surviving Corporation or any Subsidiary thereof.

     (d) The Company shall take all actions necessary to comply with
Section 5.1(1) of the Warrant Agreement, so that upon exercise of the Warrants
at any time on or after the Effective Time and payment of the exercise price,
the holder thereof shall be entitled to receive, and the Warrants shall
thereafter represent the right to receive, in lieu of Company Common Stock
issuable upon such exercise prior to the Effective Time, cash in an amount per
share of such Company Common Stock equal to the Per Share Merger Consideration. 

     SECTION 3.7  Stockholders' Meeting.  (a)  If the adoption of this
Agreement by the Company's stockholders is required by Law, the Company shall,
at Parent's request, as soon as practicable following the expiration of the
Offer, prepare and file with the SEC the Proxy Statement in preliminary form,
and each of the Company and Parent shall use its best efforts to respond as
promptly as practicable to any comments of the SEC or its staff with respect
thereto.  The Company shall notify Parent promptly of the receipt of any
comments from the SEC or its staff and of any request by the SEC or its staff
for amendments or supplements to the Proxy Statement or for additional
information and shall supply Parent with copies of all correspondence between
the Company or any of its representatives, on the one hand, and the SEC or its
staff, on the other hand, with respect to the Proxy Statement.  If at any time
prior to receipt of the Company Stockholder Approval there shall occur any
event that should be set forth in an amendment or supplement to the Proxy
Statement, the Company shall promptly prepare and mail to its stockholders such
an amendment or supplement.  The Company shall not mail any Proxy Statement, or
any amendment or supplement thereto, to which Parent reasonably objects.  The
Company shall use its best efforts to cause the Proxy Statement to be mailed to
the Company's stockholders as promptly as practicable after filing with the
SEC.  

     (b)  If the adoption of this Agreement by the Company's stockholders is
required by Law, the Company shall, at Parent's request, as soon as practicable
following the expiration of the Offer, duly call, give notice of, convene and
hold a meeting of its stockholders  (the "Company Stockholders' Meeting") for
the purpose of seeking the Company Stockholder Approval.  The Company shall,
through the Board of Directors of the Company, give the recommendation referred
to in Section 2.2.  Without limiting the generality of the foregoing, the
Company agrees that its obligations pursuant to this Section 3.7(b) shall not
be affected by the commencement, public proposal, public disclosure or
communication to the Company of any Acquisition Proposal.  Notwithstanding the
foregoing, if Purchaser or any other Subsidiary of Parent shall acquire at
least 90% of the outstanding shares of Company Common Stock, the parties shall,
at the request of Parent, take all necessary and appropriate action to cause
the Merger to become effective as soon as practicable after the expiration of
the Offer without a stockholders meeting in accordance with Section 253 of the
GCL. 

     (c)  Parent will provide the Company with the information concerning
Parent and Purchaser required to be included in the Proxy Statement and will
vote, or cause to be voted, all shares of Company Common Stock owned by it or
its Subsidiaries in favor of the adoption of this Agreement.

                                   ARTICLE IV

               CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES

     SECTION 4.1  Merger Consideration; Conversion and Cancelation of
Securities.  At the Effective Time, by virtue of the Merger and without any
action on the part of the Parent Companies, the Company or the holders of any
of the following securities:

     (a)  Subject to Section 4.3, each share of Company Common Stock (and the
related Company Right) issued and outstanding immediately prior to the
Effective Time (excluding any shares of Company Common Stock described in
Section 4.1(c)) shall be converted into the right to receive $40.00 in cash,
without interest thereon (the "Per Share Merger Consideration").

     (b) All shares of Company Common Stock converted pursuant to Section
4.1(a) shall cease to be outstanding and shall automatically be canceled and
retired, and each holder of a Certificate previously evidencing such shares of
Company Common Stock shall cease to have any rights as a stockholder of the
Company, except the right to receive the Per Share Merger Consideration for
each such share.

     (c)  All shares of Company Common Stock that are owned by the Company as
treasury stock and each share of Company Common Stock, if any, owned by Parent
or any direct or indirect wholly owned Subsidiary of Parent or of the Company
immediately prior to the Effective Time shall cease to be outstanding and shall
be automatically canceled and retired without conversion thereof, and no
consideration shall be delivered or deliverable in exchange therefor.

     (d)  Each share of common stock, par value $1.00 per share, of Purchaser
issued and outstanding immediately prior to the Effective Time shall continue
to be issued and outstanding as one fully paid and nonassessable shares of
common stock, par value $1.00 per share, of the Surviving Corporation.


     SECTION 4.2  Exchange of Certificates.

     (a)  Exchange Fund.  On the day of the Effective Time, the  Parent shall
deposit, or cause to be deposited, with the Exchange Agent in the Exchange
Fund, for the payment of the Merger Consideration through the Exchange Agent
upon surrender of Certificates in accordance with Section 4.2(c), cash in an
amount sufficient to make the cash payments due under Section 4.1(a).  The
Exchange Fund shall not be used for any other purpose except as specified in
Section 4.2(d).

     (b)  Letter of Transmittal.  As soon as reasonably practicable after the
Effective Time, Parent will cause the Exchange Agent to send 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 Exchange Agent and shall be in a form and have such other
provisions as Parent may reasonably specify) to each record holder of shares of
Company Common Stock immediately prior to the Effective Time, along with other
appropriate materials for use in surrendering Certificates to the Exchange
Agent.

     (c)  Exchange Procedures.  As soon as reasonably practicable after the
Effective Time, the Exchange Agent shall distribute to each former holder of
shares of Company Common Stock, upon surrender to the Exchange Agent for
cancelation of one or more Certificates, the Merger Consideration.  If the
Merger Consideration is to be paid to a  Person other than the Person in whose
name the surrendered Certificate or Certificates are registered, it shall be a
condition of payment of the Merger Consideration that the surrendered
Certificate or Certificates shall be properly endorsed, with signatures
guaranteed, or otherwise in proper form for transfer and that the Person
requesting such payment shall pay any transfer or other Taxes required by
reason of the payment of the Merger Consideration to a Person other than the
registered holder of the surrendered Certificate or Certificates or such Person
shall establish to the satisfaction of Parent that such Tax has been paid or is
not applicable.  Until surrendered as contemplated by this Section 4.2(c), each
Certificate shall be deemed from and after the Effective Time to represent only
the right to receive upon such surrender the Per Share Merger Consideration for
each share of Company Common Stock evidenced by such Certificate.  In no event
shall the holder of any such surrendered Certificate be entitled to receive
interest on any cash to be received in the Merger.  Neither the Exchange Agent
nor any party hereto shall be liable to a holder of shares of Company Common
Stock for any amount paid to a public official or Governmental Authority
pursuant to any applicable abandoned property, escheat, or similar Law.  If any
Certificate has not been surrendered prior to the date which is five years
after the Effective Time (or immediately prior to such earlier date on which
Merger Consideration in respect of such Certificate would otherwise escheat to
or become the property of any Governmental Authority), any such cash in respect
of such Certificate shall, to the extent permitted by applicable Law, become
the property of the Surviving Corporation, free and clear of all claims or
interest of any Person previously entitled thereto.

     (d)  Termination of Exchange Fund.  Any portion of the Exchange Fund which
remains unclaimed by the former holders of shares of Company Common Stock for
six months after the Effective Time shall be delivered to Parent, upon demand,
and any former holders of shares of Company Common Stock who have not
theretofore complied with this Article IV shall thereafter look only to Parent
for any cash payment to which they are entitled.

     (e)  Investment of Exchange Fund.  The Exchange Agent shall invest any
cash included in the Exchange Fund, as directed by Parent, on a daily basis. 
Any interest and other income resulting from such investments shall be paid to
Parent.

     (f)  Withholding of Tax.  Parent shall be entitled to deduct and withhold
from the consideration otherwise payable pursuant to this Agreement to any
former holder of shares of Company Common Stock such amounts as Parent (or any
Affiliate thereof) is required to deduct and withhold with respect to the
making of such payment under the Code, or any provision of state, local or
foreign Tax Law.  To the extent that amounts are so withheld by Parent and paid
by Parent to the applicable taxing authority, such withheld amounts shall be
treated for all purposes of this Agreement as having been paid to the former
holder of shares of Company Common Stock in respect of which such deduction and
withholding was made by Parent.

     SECTION 4.3  Dissenting Shares.  Notwithstanding anything in this
Agreement to the contrary, shares of Company Common Stock ("Dissenting Shares")
which are issued and outstanding immediately prior to the Effective Time and
that are held by any Person who is entitled to demand and properly demands
appraisal of such Dissenting Shares pursuant to, and who complies in all
respects with, Section 262 of the GCL ("Section 262") shall not be converted as
provided in Section 4.1(a), but rather the holders of Dissenting Shares shall
be entitled only to payment of the fair  value of such Dissenting Shares in
accordance with Section 262; provided, however, that if any such holder shall
fail to perfect or otherwise shall waive, withdraw or lose the right to
appraisal under Section 262, then the right of such holder to be paid the fair
value of such holder's Dissenting Shares shall cease and such Dissenting Shares
shall be treated as if they had been converted as of the Effective Time into
the Merger Consideration as provided in Section 4.1(a).  The Company shall
serve prompt notice to Parent of any demands received by the Company for
appraisal of any shares of Company Common Stock, and Parent shall have the
right to participate in and direct all negotiations and proceedings with
respect to such demands.  The Company shall not, except with the prior written
consent of Parent, make any payment with respect to, or settle or offer to
settle, any such demands, or agree to do any of the foregoing.

     SECTION 4.4  Closing.  The closing (the "Closing") of the Merger shall
take place at the offices of Cravath, Swaine & Moore, at 825 Eighth Avenue, New
York, NY at 10 a.m. on a date as soon as practicable following the date on
which the conditions to the Closing (other than those that, by their terms, are
to be satisfied at the Closing) have been satisfied or waived, or at such other
place, time and date as the parties hereto may agree.  At the conclusion of the
Closing on the Closing Date, the parties hereto shall cause the Certificate of
Merger to be filed with the Secretary of State of the State of Delaware.

     SECTION 4.5  Stock Transfer Books.  At the Effective Time, the stock
transfer books of the Company shall be closed and there shall be no further
registration of transfers of shares of Company Common Stock thereafter on the
records of the Company.

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     The Company hereby represents and warrants to the Parent Companies that:

of incorporation or organization, have all requisite power and authority and
possess all governmental franchises and Permits necessary to enable them to
own, lease and operate their respective properties and assets and to carry on
their business as it is now being conducted and are duly qualified and in good
standing to do business in each jurisdiction in which the nature of the
business conducted by them or the ownership or leasing of their respective
properties and assets makes such qualification necessary, other than such
franchises and Permits and qualifications the lack of which, individually or in
the aggregate, has not had and could not reasonably be expected to have a
Material Adverse Effect on the Company.  Section 5.1 of the Company's
Disclosure Letter sets forth, as of the date of this Agreement, a true and
complete list of all the Company's directly or indirectly owned Subsidiaries,
together with the jurisdiction of incorporation of each Subsidiary and the

Subsidiaries owns an equity interest in any partnership or joint venture
arrangement or other business entity.

     SECTION 5.2  Certificate of Incorporation and Bylaws.  The Company has
heretofore furnished or made available to Parent complete and correct copies of

capital stock of the Company or any of its Subsidiaries or with respect to the
registration of the offering, sale or delivery of any shares of capital stock

Company has delivered to Parent a complete and correct copy of the Company's
Rights Agreement, as amended to the date of this Agreement.

     (e)  There are not any bonds, debentures, notes or other Indebtedness of

     SECTION 5.4  Authorization of Agreement.  (a)  The Company has all
requisite corporate power and authority to execute and deliver this Agreement

delivery by the Company of this Agreement and each instrument required hereby
to be executed and delivered by it prior to or at the Closing and the
performance of its obligations hereunder and thereunder have been duly and
validly authorized by all requisite corporate action on the part of the Company
(other than, with respect to the Merger, the adoption of this Agreement by the
holders of a majority of the outstanding shares of Company Common Stock in
accordance with the GCL).  This Agreement has been duly executed and delivered
by the Company and (assuming due authorization, execution and delivery hereof
by the other parties hereto) constitutes a legal, valid and binding obligation
of the Company, enforceable against the Company in accordance with its terms,
except as the same may be limited by (i) bankruptcy, insolvency,
reorganization, moratorium, fraudulent conveyance or other similar Laws
relating to creditors' rights generally, and (ii) legal principles of general
applicability governing the application and availability of equitable
remedies.

     (b)  The only vote of holders of any class or series of capital stock of
the Company necessary to adopt or approve this Agreement and the Merger is the
adoption of this Agreement by the holders of a majority of the outstanding
shares of Company Common Stock (the "Company Stockholder Approval").  The
affirmative vote of the holders of any capital stock of the Company, or any of
them, is not necessary to consummate the Offer or any transaction contemplated
by this Agreement other than the Merger.

     SECTION 5.5  Approvals.  Except for the applicable requirements, if any,
of (a) the Exchange Act, (b) state securities Laws or blue sky Laws, (c) the

appropriate merger documents as required by the GCL, (g) the National
Industrial Security Program Operating Manual with respect to foreign ownership,
control or influence and (h) those Laws and Orders noncompliance with which
could not reasonably be expected to have a material adverse effect on the
ability of the Company to perform its obligations under this Agreement or to
have a Material Adverse Effect on the Company, no filing or registration with,
no waiting period imposed by and no Permit or Order of, any Governmental
Authority is required under any Law or Order applicable to the Company or any
of its Subsidiaries to permit the Company to execute, deliver or perform this
Agreement or any instrument required hereby to be executed and delivered by it
prior to or at the Closing.

     SECTION 5.6  No Violation.  Assuming effectuation of all filings and
registrations with, termination or expiration of any applicable waiting periods
imposed by and receipt of all Permits and Orders of, Governmental Authorities
indicated as required in Section 5.5 and adoption of this Agreement by the
stockholders of the Company as required by the GCL and except as set forth in
Section 5.6 of the Company's Disclosure Letter, neither the execution and
delivery by the Company of this Agreement or any instrument required hereby to
be executed and delivered by it prior to or at the Closing nor the performance
by the Company of its obligations hereunder or thereunder will (a) conflict
with, or result in any violation of or default (with or without notice or lapse
of time, or both) under, or give rise to a right of termination, cancelation or
acceleration of any obligation or to loss of a Material benefit under, or to
increased, additional, accelerated or guaranteed rights or entitlements of any
Person under, or result in the creation of any Lien upon any of the properties
or assets of the Company or any Subsidiary of the Company under, any provision
of (i) any Law or Order applicable to the Company, (ii) the certificate of
incorporation or bylaws of the Company or (iii) any contract or agreement to
which the Company or any of its Subsidiaries is a party or by which the Company
or any of its Subsidiaries or any of their respective properties or assets is
bound, or (b) with the passage of time, the giving of notice or the taking of
any action by a third Person, have any of the effects set forth in clause (a)
of this Section, except in any such case for any matters described in this
Section that could not reasonably be expected to have a Material Adverse Effect
on the Company.  Prior to the execution of this Agreement, the Board of
Directors of the Company has taken all necessary action to cause this
Agreement, the Stockholders Agreement and the transactions contemplated or
permitted hereby and thereby to be exempt from the provisions of Section 203 of
the GCL and to cause any Company Rights not to be distributed or exercisable
under the Company's Rights Agreement.  To the Company's Knowledge, no other
state takeover statute or similar Law or Regulation applies or purports to
apply to the Company with respect to this Agreement, the Stockholders
Agreement, the Offer, the Merger or any other transaction contemplated by this
Agreement or the Stockholders Agreement.  The Company has been advised by each
of its directors and executive officers that each such Person currently intends
to tender all shares of Company Common Stock owned by such Person pursuant to
the Offer, except to the extent of any restrictions created by Section 16(b) of
the Exchange Act.

Company with the SEC since January 1, 1997 (the "Company SEC Documents").  As of
its respective date, each Company SEC Document complied in all material respects
with the requirements of the Exchange Act or the Securities Act, as the case may
be, applicable to such Company SEC Document, and did not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading.  Except to the
extent that information contained in any Company SEC Document has been revised
or superseded by a later filed Company SEC Document, none of the Company SEC
Documents contains any untrue statement of a material fact or omits to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading.  No Subsidiaries of the Company are SEC reporting companies.

     (b)  Since December 31, 1997, the Company and its Subsidiaries have filed
all Reports required to be filed with any Governmental Authorities other than
the SEC, including state securities administrators, except where the failure to
file any such Reports of the Company would not reasonably be expected to have a
Material Adverse Effect on the Company.  Such Reports of the Company, including
all those filed after the date of this Agreement and prior to the Effective
Time, were prepared in all material respects in accordance with the requirements
of applicable Law.

     (c)  The Company Consolidated Financial Statements and any consolidated
financial statements of the Company (including any related notes thereto)
contained in any SEC Reports of the Company filed with the SEC (i) have been or
will have been prepared in accordance with applicable accounting requirements
and the published Regulations of the SEC and in accordance with GAAP
consistently applied (except (A) to the extent required by changes in GAAP and
(B) with respect to SEC Reports of the Company filed prior to the date of this
Agreement, as may be indicated in the notes thereto) and (ii) fairly present the
consolidated financial position of the Company and its consolidated Subsidiaries
as of the respective dates thereof and the consolidated results of their
operations and cash flows for the periods indicated (and include, in the case of
any unaudited interim financial statements, reasonable accruals for normal 
year-end adjustments).

     SECTION 5.8  No Undisclosed Liabilities.  Except as set forth in
Section 5.8 of the Company's Disclosure Letter, there exist no liabilities or
obligations of the Company and its Subsidiaries that are Material to the
Company, whether accrued, absolute, contingent or otherwise, which would be
required to be reflected, reserved for or disclosed under GAAP in consolidated
financial statements of the Company (including the notes thereto) as of and for
the period ended on the date this representation and warranty is given or
required to be true to satisfy any condition to the Offer or the Merger, other
than (a) liabilities or obligations that are adequately reflected, reserved for
or disclosed in the Company's Consolidated Financial Statements and,
(b) liabilities or obligations incurred in the ordinary course of business of
the Company since the Balance Sheet Date not in violation of this Agreement. 
Except as set forth in Section 5.8 of the Company's Disclosure Letter, neither
the Company nor any of its Subsidiaries has any liability for any discontinued
operations (as such term is used in accordance with GAAP) or with respect to any
business, properties or assets formerly owned or operated by the Company or any
of its Subsidiaries or with respect to any acquiree or predecessor of the
Company or any of its Subsidiaries, that would individually or in the aggregate
have a Material Adverse Effect on the Company.

     SECTION 5.9  No Material Adverse Effect; Conduct.

     Except as disclosed in the Company SEC Documents filed and publicly
available prior to the date of this Agreement (the "Filed Company SEC
Documents") or in Section 5.9 of the Company Disclosure Letter, from the date of
the most recent audited financial statements included in the Filed Company SEC
Documents, the Company has conducted its business only in the ordinary course,
and during such period there has not been:

     (a)  any event, change, effect or development that, individually or in
the aggregate, has had or could reasonably be expected to have a Material
Adverse Effect on the Company;

     (b)  any declaration, setting aside or payment of any dividend on, or other
distribution in respect of (whether in cash, stock or property), any capital
stock of the Company or any repurchase for value by the Company of any capital
stock of the Company;

     (c)  any split, combination or reclassification of any capital stock of the
Company or of any other equity interests in the Company, or any issuance or the
authorization of any issuance of any other securities in respect of, in lieu of
or in substitution for shares of capital stock of the Company or of any other
equity interests in the Company;

     (d) (i) any granting by the Company or any Subsidiary of the Company to
any director or executive officer of the Company or any Subsidiary of the
Company of any increase in compensation, except in the ordinary course of
business consistent with past practice or as was required under employment
agreements in effect as of the date of the most recent audited financial
statements included in the Filed Company SEC Documents, (ii) any granting by the
Company or any Subsidiary of the Company to any such director or executive
officer of any increase in severance or termination pay, except as was required
under any employment, severance or termination agreements in effect as of the
date of the most recent audited financial statements included in the Filed
Company SEC Documents, or (iii) any entry by the Company or any Subsidiary of
the Company into any employment, severance or termination agreement with any
such director or executive officer; or 

     (e)  any change in accounting methods, principles or practices by the
Company or any Subsidiary of the Company materially affecting the consolidated
assets, liabilities or results of operations of the Company, except insofar as
may have been required by a change in GAAP.

of the information (other than information provided in writing by Parent or
Purchaser for inclusion therein) supplied or to be supplied for inclusion or
incorporation by reference in the Offer Documents, the Schedule 14D-9 or the
Proxy Statement, including any amendments or supplements thereto, at the time
such document is filed with the SEC, at any time it is amended or supplemented
or at the time it is first published or sent or given to holders of shares of
Company Common Stock, and, in the case of the Proxy Statement, at the time that
it or any amendment or supplement thereto is mailed to the Company's
stockholders, at the time of the Company Stockholders' Meeting or at the
Effective Time, will contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary in order to
make the statements therein, in light of the circumstances under which they are
made, not misleading.  Except for information supplied by Parent or Purchaser in
writing for inclusion therein, the Schedule 14D-9 and the Proxy Statement,
including any amendments or supplements thereto, will comply in all material
respects with the Exchange Act.

     SECTION 5.11  Properties and Assets.  Except as set forth in Section 5.11
of the Company's Disclosure Letter, the Company and its Subsidiaries own or have
rights to use all properties and assets necessary to permit the Company and its
Subsidiaries to continue to conduct their businesses as currently being
conducted except where the failure to own or have the right to use such
properties and assets would not, individually or in the aggregate, have a
Material Adverse Effect on the Company.  Except as set forth in Section 5.11 of
the Company Disclosure Letter, each of the Company and its Subsidiaries has good
and indefeasible fee title to, or valid leasehold interests in, all its material
real property, free and clear of all Liens except for Permitted Encumbrances.

it will not, and will not permit any of its Subsidiaries, or any of its or their
officers, directors, employees, representatives, agents, or Affiliates,
including any investment banker, attorney, or accountant retained by the Company
or any of its Subsidiaries (collectively, "Representatives"), to, directly or

Representative, relating to any of such matters; provided however, that nothing
contained in this Agreement shall prohibit the Board of Directors of the Company
at any time prior to the earlier to occur of acceptance for payment of shares of
Company Common Stock pursuant to the Offer or adoption of this Agreement by the
stockholders of the Company from furnishing information (pursuant to a customary
confidentiality agreement no more favorable to the party receiving information
than the Confidentiality Agreement and consistent with the Company's obligations
under this Agreement, including Section 7.3(c)) to, or engaging in discussions
or negotiations with, any Person in response to an unsolicited bona fide written
Acquisition Proposal of such Person that satisfies the requirements of a
Superior Proposal, if, and only to the extent that, (A) the Board of Directors
of the Company, after consultation with outside legal counsel to the Company,
determines in good faith that failure to do so would result in a breach of the
fiduciary duty of the Board of Directors of the Company to the stockholders of
the Company under applicable Law, and (B) prior to furnishing such information
to, or entering into discussions or negotiations with, such Person the Company
provides written notice to Parent to the effect that it is furnishing
information to, or entering into discussions or negotiations with, such Person
and the Company complies with Section 7.3(c).  Taking the actions contemplated
by the proviso to the prior sentence under the circumstances described therein
will not be deemed to be a breach of this Agreement.  It is understood that any
violation of the restrictions set forth in this Section 7.3 by any
Representative of the Company or any of its Subsidiaries, whether nor not such
Person is purporting to act on behalf of the Company or otherwise, shall be
deemed to be a breach of this Section 7.3 by the Company.

     (b)  Except as expressly permitted by this Section 7.3, neither the Board
of Directors of the Company nor any committee thereof shall (i) withdraw or
modify, or propose publicly to withdraw or modify, in a manner adverse to Parent
or Purchaser, the approval or recommendation by such Board of the Offer or the
Merger as set forth in Section 2.2, (ii) approve or recommend, or propose
publicly to approve or recommend, any Acquisition Proposal, or (iii) cause the
Company to enter into any letter of intent, agreement in principle, acquisition
agreement or other similar agreement (each, an "Acquisition Agreement") related
to any Acquisition Proposal.  Notwithstanding the foregoing, prior to the
earlier to occur of acceptance for payment of shares of Company Common Stock
pursuant to the Offer or adoption of this Agreement by the stockholders of the
Company, the Board of Directors of the Company may terminate this Agreement but
only (A) to the extent that the Board of Directors of the Company, after
consultation with outside legal counsel to the Company, determines in good faith
that failure to do so would result in a breach of the fiduciary duty of the
Board of Directors to the stockholders of the Company under applicable Law, 
(B)if the Company and the Board of Directors of the Company have complied with
all the provisions of this Section 7.3, (C) after the third day following
Parent's receipt of written notice advising Parent that the Board of Directors
of the Company is prepared to accept a Superior Proposal, specifying the
principal terms and conditions of such Superior Proposal and identifying the
Person making such Superior Proposal and (D) if concurrently with such
termination, the Company enters into an Acquisition Agreement with respect to
such Superior Proposal and pays to Parent the Termination Fee and the
out-of-pocket fees and expenses incurred by Parent, Purchaser and their
Affiliates in connection with the transactions contemplated by this Agreement
pursuant to Section 9.5(b).

     (c)  In addition to the obligations of the Company set forth in
paragraphs (a) and (b) of this Section 7.3, the Company shall promptly advise
Parent, orally and in writing, of any request for information or of any
Acquisition Proposal, the principal terms and conditions of such request or
Acquisition Proposal and the identity of the Person making such request or
Acquisition Proposal.  The Company shall keep Parent reasonably informed of the
status and details (including amendments or proposed amendments) of any such
request or Acquisition Proposal.

     (d)  "Acquisition Proposal" means an inquiry, offer or proposal regarding
any of the following (other than the transactions contemplated by this
Agreement) involving the Company:  (i) any merger, consolidation, share
exchange, recapitalization, liquidation, dissolution, business combination or
other similar transaction; (ii) any sale, lease, exchange, mortgage, pledge,
transfer or other disposition of a substantial portion of the assets of the
Company and its Subsidiaries, taken as a whole, or of any Material Business or
of any Subsidiary or Subsidiaries responsible for a Material Business in a
single transaction or series of related transactions; (iii) any acquisition of
15 percent or more of the outstanding shares of capital stock of the Company or
the filing of a registration statement under the Securities Act in connection
therewith or any other acquisition or disposition the consummation of which
would prevent or materially diminish the benefits to Parent of the Merger; or
(iv) any public announcement of a proposal, plan or intention to do any of the
foregoing or any agreement to engage in any of the foregoing.  "Superior
Proposal" means any proposal made by a third party to acquire, directly or
indirectly, including pursuant to a tender offer, exchange offer, merger,
consolidation, share exchange, business combination, recapitalization,
liquidation, dissolution or other similar transaction, for consideration
consisting of cash and/or marketable securities, all the shares of Company
Common Stock then outstanding or not less than 75 percent of the assets of the
Company and its Subsidiaries which the Board of Directors of the Company
determines in good faith (based on advice of a financial advisor of nationally
recognized reputation) to be superior to the Company's stockholders from a
financial point of view (taking into account any changes to the financial terms
of this Agreement proposed by Parent in response to such proposal) and to be
more favorable generally to the Company's stockholders (taking into account all
financial and strategic considerations, including relevant legal, financial,
regulatory and other aspects of such proposal and the third party making such
proposal and the conditions and prospects for completion of such proposal, and
any changes to this Agreement proposed by Parent in response to such proposal)
than the Offer, the Merger and the other transactions contemplated by this
Agreement, taken as a whole.  "Material Business" means any business (or the
assets needed to carry out such business) that contributed or represented 15% or
more of the net sales, the net income or the assets (including equity
securities) of the Company and its Subsidiaries taken as a whole.

     (e)  Nothing contained in this Section 7.3 shall prohibit the Company
from taking and disclosing to its stockholders a position contemplated by
Rule 14e-2(a) promulgated under the Exchange Act or from making any disclosure
to the Company's stockholders which the Board of Directors of the Company, after
consultation with outside legal counsel to the Company, determines in good faith
is required by the fiduciary duty of the Board of Directors to the stockholders
of the Company under applicable Law; provided that neither the Board of
Directors of the Company nor any committee thereof withdraws or modifies, or
proposes to withdraw or modify, the approval or recommendation of such Board of
the Offer or the Merger as set forth in Section 2.2 or approves or recommends,
or publicly proposes to approve or recommend, an Acquisition Proposal unless the
Company and the Board of Directors of the Company have complied with all the
provisions of this Section 7.3.

     SECTION 7.4  Access to Information.  Between the date of this Agreement and
the Effective Time, the Company shall, and shall cause its Subsidiaries to,
(a) afford to Parent and its officers, directors, employees, accountants,
consultants, legal counsel, agents and other representatives full access during
normal business hours and at all other reasonable times to the officers,
employees, agents, properties, offices and other facilities of the Company and
its Subsidiaries and to their books and records and (b) furnish promptly to
Parent and its Representatives a copy of each report, schedule, registration
statement and other document filed by it during such period pursuant to the
requirements of federal or state securities Laws and such other information
concerning the business, properties, contracts, records and personnel of the
Company and its Subsidiaries (including financial, operating and other data and
information) as may be reasonably requested, from time to time, by or on behalf
of Parent.

     SECTION 7.5  Confidentiality Agreement.  The parties agree that the
provisions of the Confidentiality Agreement shall remain binding and in full
force and effect and that the terms of the Confidentiality Agreement are
incorporated herein by reference; provided, however, that any consents from the
Company necessary under the Confidentiality Agreement for Parent and Purchaser
to consummate the transactions contemplated by this Agreement and the
Stockholders Agreement shall be deemed to have been made.  The parties shall
comply with, and shall cause their respective Representatives to comply with,
all of their respective obligations under the Confidentiality Agreement until
Purchaser purchases a majority of the outstanding shares of Company Common Stock
pursuant to the Offer.

     SECTION 7.6  Reasonable Efforts.  Subject to the terms and conditions of
this Agreement and, including the provisions of Sections 7.7 and 7.8, each of
the parties hereto agrees to use all reasonable efforts to take, or cause to be
taken, all action, and to do, or cause to be done, all things reasonably
necessary, proper or advisable under applicable Laws to consummate and make
effective as soon as reasonably practicable the transactions contemplated by
this Agreement including (a) cooperating in the preparation and filing of all
applications, requests, consents and other filings required by applicable
Governmental Authorities or Courts, including the Offer Documents, the
Schedule 14D-9, the Proxy Statement and any amendments and supplements to any
thereof; (b) taking all action reasonably necessary, proper or advisable to
secure any necessary consents, approvals or waivers from third parties,
including under existing debt obligations of the Company and its Subsidiaries or
to amend the notes, indentures or agreements relating to such existing debt
obligations to the extent required by such notes, indentures or agreements, or
to redeem or repurchase such debt obligations; (c) contesting any pending legal
proceeding, whether judicial or administrative, relating to the Offer or the
Merger including seeking to have any stay or temporary restraining order entered
by any Court or other Governmental Authority vacated or reversed; and
(d) executing any additional instruments necessary to consummate the
transactions contemplated hereby and thereby.  In case at any time after the
Effective Time any further action is necessary to carry out the purposes of this
Agreement, the proper officers and directors of each party hereto shall use all
reasonable efforts to take all such necessary action.

     SECTION 7.7  Permits.  Each of the Company, Parent and Purchaser shall
cooperate and use their respective reasonable efforts to make all filings, to
obtain all actions or nonactions, waivers, Permits and Orders of Governmental
Authorities necessary to consummate the transactions contemplated by this
Agreement and to take all reasonable steps as may be necessary to obtain an
approval or waiver from, or to avoid an action or proceeding by, any
Governmental Authority.  Each of the parties hereto will furnish to the other
parties such necessary information and reasonable assistance as such other
parties may reasonably request in connection with the foregoing.

     SECTION 7.8  HSR Act and Exon-Florio Filings.

     (a)  In addition to and without limiting the agreements of Parent,
Purchaser and the Company contained in Sections 7.6 and 7.7, Parent, Purchaser
and the Company will (i) take promptly all actions necessary to make the filings
required of Parent, Purchaser, the Company or any of their Affiliates under the
HSR Act and Exon-Florio, (ii) comply at the earliest practicable date with any
request for additional information or documentary material received by Parent,
Purchaser, the Company or any of their respective Affiliates from the Federal
Trade Commission or the Antitrust Division of the Department of Justice pursuant
to the HSR Act, or from CFIUS under Exon-Florio, and (iii) cooperate in
connection with resolving any investigation or other inquiry concerning the
transactions contemplated by this Agreement (A) under the HSR Act commenced by
the Federal Trade Commission or the Antitrust Division of the Department of
Justice, or (B) under Exon-Florio, commenced by CFIUS.

     (b)  In furtherance and not in limitation of the covenants contained in
Section 7.7 and Section 7.8(a), Parent, Purchaser and the Company shall each use
all reasonable efforts to resolve such objections, if any, as may be asserted
with respect to the Offer, the Merger or any other transactions contemplated by
this Agreement under the HSR Act or Exon-Florio; provided, that neither Parent
nor any of its Subsidiaries shall be required to divest any asset or enter into
any consent decree.

     (c) Each of the Company, Parent and Purchaser shall promptly inform the
other party of any material communication received by such party from the
Federal Trade Commission, the Antitrust Division of the Department of Justice,
CFIUS, or any other Governmental Authority regarding any of the transactions
contemplated hereby.

     SECTION 7.9  Public Announcements.  Parent, Purchaser and the Company will
consult with each other before issuing any press release or otherwise making any
public statements with respect to the Offer or the Merger or this Agreement and
shall not issue any such press release or make any such public statement prior
to such consultation (and affording the other party or parties an opportunity to
comment thereon), except as may be required by applicable Law or  Court process
or by obligations pursuant to any listing agreement with the NASD or any
securities exchange.

     SECTION 7.10  Employee Agreements.

     Parent acknowledges and agrees that all employment agreements,
severance agreements, deferred compensation agreements, and supplemental
retirement agreements with the employees of the Company and its Subsidiaries
that are listed in Section 7.10 of the Company's Disclosure Letter will be
binding and enforceable obligations of the Surviving Corporation to the same
extent as they were binding and enforceable obligations of the Company and its
Subsidiaries as of the date of this Agreement, except as the parties thereto may
otherwise agree.

     SECTION 7.11  Company's Rights Agreement; State Takeover Statutes. 
The Company shall take all action (including, if necessary, redeeming all the
outstanding Company Rights issued pursuant to the Company's Rights Agreement or
amending or terminating the Company's Rights Agreement) so that the execution,
delivery and performance of this Agreement and the Stockholders Agreement and
the consummation of the Merger and the other transactions contemplated or
permitted by this Agreement and the Stockholders Agreement do not and will not
result in the grant of any Company Rights to any Person under the Company's
Rights Agreement or enable or require any outstanding Company Rights to be
exercised, distributed or triggered.  Except as set forth in the first sentence
of this Section 7.11 or as approved in writing by Parent, the Board of Directors
of the Company shall not (a) amend the Company's Rights Agreement or (b) take
any action with respect to, or make any determination under, the Company's
Rights Agreement.  If any Distribution Date or Shares Acquisition Date occurs
under the Company's Rights Agreement at any time during the period from the date
of this Agreement to the Effective Time, the Company and Parent shall make such
adjustment to the Offer price as the Company and Parent shall mutually agree so
as to preserve the economic benefits that the Company and Parent each reasonably
expected on the date of this Agreement to receive as a result of the
consummation of the Offer, the Merger and the other transactions contemplated by
this Agreement.  The Company will take all steps necessary (a) to exempt the
transactions contemplated by this Agreement and the Stockholders Agreement from
Section 203 of the GCL, (b) to ensure that no other state takeover statute or
similar Law or Regulation is or becomes applicable to this Agreement or the
Stockholders Agreement and (c) if any state takeover statute or similar Law or
Regulation becomes applicable to this Agreement or the Stockholders Agreement,
to ensure that the Offer, the Merger and the other transactions contemplated
hereby and thereby may be consummated as promptly as practicable on the terms
contemplated by this Agreement and the Stockholders Agreement and otherwise to
minimize the effect of such Law or Regulation on the Offer, the Merger and the
other transactions contemplated hereby and thereby.

     SECTION 7.12  Employee Benefit Plans. Until at least December 31,
1998, Parent shall provide, or cause to be provided, to all employees of the
Company and its Subsidiaries compensation, incentive pay and benefits that are
substantially comparable in the aggregate to the compensation, incentive pay and
benefits (without taking into account any equity-based compensation, incentive
pay or benefits) provided to such employees by the Company and its Subsidiaries
as of the Offer Closing Date.  From and after the Effective Time, Parent shall
grant all employees of the Surviving Corporation and its Subsidiaries on the
Effective Time credit for vesting and eligibility purposes (but not for benefit
accrual purposes) for all service (to the same extent as service with Parent or
any Subsidiary of Parent (other than the Surviving Corporation and its
Subsidiaries) is taken into account with respect to similarly situated employees
of Parent and the Subsidiaries of Parent (other than the Surviving Corporation
and its Subsidiaries)) with the Surviving Corporation and any Subsidiary of the
Surviving Corporation and their respective predecessors prior to the Effective
Time under all Benefit Plans of Parent or its Subsidiaries (other than the
Surviving Corporation and its Subsidiaries) in which such employees shall become
eligible to participate as if such service with the Surviving Corporation or any
Subsidiary of the Surviving Corporation and their respective predecessors was
service with Parent or any Subsidiary of Parent (other than the Surviving
Corporation and its Subsidiaries), and, with respect to any medical or dental
benefit plan in which such employees become eligible to participate, Parent
shall waive any pre-existing condition exclusions and actively-at-work
requirements (provided, however, that no such waiver shall apply to a pre-
existing condition of any employee of the Surviving Corporation or any
Subsidiary of the Surviving Corporation who was, as of the Offer Closing Date,
excluded from participation in a Benefit Plan of the Surviving Corporation or
any Subsidiary of the Surviving Corporation by virtue of such pre-existing
condition) and provided that any covered expenses incurred (on or before the
Offer Closing Date) by an employee or an employee's covered dependent shall be
taken into account for purposes of satisfying applicable deductible, coinsurance
and maximum out-of-pocket provisions after the Offer Closing Date to the same
extent as such expenses are taken into account for the benefit of similarly
situated employees of Parent and the Subsidiaries of Parent (other than the
Surviving Corporation and its Subsidiaries).

     SECTION 7.13  Indemnification of Directors and Officers.

     (a)  Purchaser agrees that all rights to indemnification for acts or
omissions occurring prior to the Offer Closing Date existing as of the date
hereof in favor of the current or former directors or officers of the Company
and its Subsidiaries as provided in their respective certificates of
incorporation or bylaws shall survive the Merger and shall continue in full
force and effect in accordance with their terms for a period of six years from
the Offer Closing Date.  Parent shall cause to be maintained for a period of six
years from the Offer Closing Date the Company's current directors' and officers'
insurance and indemnification policy (the "D&O Insurance") and the current
fiduciary liability insurance policy (the "Fiduciary Insurance") (provided that
Parent may substitute therefor policies or financial guarantees with reputable
and financially sound carriers or other obligors of at least the same coverage
and amounts containing terms and conditions which are no less advantageous) to
the extent that such insurance policies provide coverage for events occurring
prior to the Effective Time for all persons who are directors and officers of
the Company on the date of this Agreement, so long as the aggregate amount to be
paid by the Company after the date of this Agreement for such D&O Insurance and
Fiduciary Insurance during such six-year period would not be in excess of
$350,000 and $150,000, respectively.  If, during such six-year period, such
insurance coverage cannot be obtained at all or can only be obtained for an
aggregate amount (including all amounts paid by the Company after the date of
this Agreement) in excess of $350,000, in the case of D&O Insurance, and
$150,000, in the case of Fiduciary Insurance,  Parent shall use all reasonable
efforts to cause to be obtained as much D&O Insurance and Fiduciary Insurance as
can be obtained for the remainder of such six-year period for an aggregate
amount (including all amounts paid by the Company after the date of this
Agreement) not in excess of $350,000 and $150,000, respectively, on terms and
conditions no less advantageous than the existing D&O Insurance and the existing
Fiduciary Insurance, respectively.

     (b)  If any claim or claims shall, subsequent to the Offer Closing Date
and within six years thereafter, be made in writing against any present or
former director or officer of the Company based on or arising out of the
services of such Person prior to the Offer Closing Date in the capacity of such
Person as a director or officer of the Company (and such director or officer
shall have given Parent written notice of such claim or claims within such six
year period), the provisions of subsection (a) of this Section respecting the
rights to indemnity for current or former directors or officers under the
certificate of incorporation and bylaws of the Company and its Subsidiaries
shall continue in effect until the final disposition of all such claims.

     (c)  Notwithstanding anything to the contrary in this Section 7.13, neither
Parent nor the Surviving Corporation shall be liable for any settlement
effected without its written consent, which shall not be unreasonably withheld.

     (d)  The provisions of this Section 7.13 are intended to be for the benefit
of, and shall be enforceable by, each Person entitled to indemnification
hereunder and the heirs and representatives of such Person.

     (e)  Parent shall not permit the Surviving Corporation to merge or
consolidate with any other Person unless the Surviving Corporation shall ensure
that the surviving or resulting entity assumes the obligations imposed by
subsections (a) and  (b) of this Section 7.13.

     SECTION 7.14  Event Notices and Other Actions.  (a) From and after the
date of this Agreement until the Effective Time, each party hereto shall
promptly notify the other parties hereto of (i) the occurrence or nonoccurrence
of any event, the occurrence or nonoccurrence of which has resulted in, or could
reasonably be expected to result in, any condition to the Offer set forth in
Annex B, or any condition to the Merger set forth in Article VIII, not being
satisfied, (ii) the failure of such party to comply with any covenant or
agreement to be complied with by it pursuant to this Agreement which has
resulted in, or could reasonably be expected to result in, any condition to the
Offer set forth in Annex B, or any condition to the Merger set forth in Article
VIII, not being satisfied and (iii) any representation or warranty made by it
contained in this Agreement that is qualified as to materiality becoming untrue
or inaccurate in any respect or any such representation or warranty that is not
so qualified becoming untrue or inaccurate in any material respect.  No delivery
of any notice pursuant to this Section 7.14(a) shall cure any breach of any
representation or warranty of such party contained in this Agreement or
otherwise limit or affect the remedies available hereunder to the party or
parties receiving such notice.

     (b)  The Company and Parent shall not, and shall not permit any of their
respective Subsidiaries to, take any action or nonaction that would, or that
could reasonably be expected to, result in (i) any of the representations and
warranties of such party set forth in this Agreement that is qualified as to
materiality becoming untrue, (ii) any of such representations and warranties
that is not so qualified becoming untrue in any material respect or (iii) except
as otherwise permitted by Section 7.3, any condition to the Offer set forth in
Annex B, or any condition to the Merger set forth in Article VIII, not being
satisfied.

     SECTION 7.15  Third Party Standstill Agreements; Tortious Interference. 
During the period from the date of this Agreement through the Effective Time,
the Company shall not terminate, amend, modify or waive any provision of any
confidentiality or standstill or similar agreement to which the Company or any
of its Subsidiaries is a party (other than any involving Parent).  Subject to
the foregoing, during such period, the Company agrees to enforce, to the fullest
extent permitted under applicable Law, the provisions of any such agreements,
including obtaining injunctions to prevent any breaches of such agreements and
to enforce specifically the terms and provisions thereof in any Court of the
United States or any state thereof having jurisdiction.  Notwithstanding the
foregoing, nothing in this Section 7.15 is intended to prevent the Company from
exercising its rights under Section 7.3(a) in accordance with the provisions of
Section 7.3.

contained therein), as of the date of this Agreement and as of the Effective
Time as though made as of the Effective Time, (other than to the extent such
representations and warranties expressly relate to an earlier date, in which
case such representations and warranties shall be true and correct as of such

Disclosure Schedule for Section 5.16(c)

A.  The attached listing reports the extended due date for the filing of any
material income tax return.  All extensions have either been applied for, are
automatically granted, or will be requested prior to the initial filing date if
the return will not be filed by such due date.

B.  The only outstanding waiver or agreement for extension of time for the
assessment or payment of any material income tax is for GDE Holdings, Inc. and
Subsidiaries (GDE) for the federal income tax periods ended December 31, 1992
and December 31, 1993.  On February 13, 1997 a US Form 872-A, Special Consent
to Extend the Time to Assess Tax, was executed for the respective periods.  By
filing US Form 872-T, Notice of Termination of Special Consent to Extend the
Time to Assess Tax, on April 6, 1998, the IRS was notified of GDE's intent for
the statute of limitations for the assessment or payment of federal income tax
with respect to such periods to be terminated by the 90th day following the 
IRS's receipt of such notice.
