         WHEREAS, Parent, Parent Sub and Target have entered into that certain
Agreement and Plan of Merger dated October 29, 1997 (the "Original Merger
Agreement");

         WHEREAS, Parent, Parent Sub and Target desires to amend, restate and
modify the Original Merger Agreement in its entirety as set forth in this
Agreement;

         WHEREAS, Parent Sub, upon the terms and subject to the conditions of
this Agreement and in accordance with the Delaware General Corporation Law
("Delaware Law"), will merge with and into Target (the "Merger") and as a
result of the Merger, the separate corporate existence of Parent Sub shall
cease and Target shall continue as the surviving corporation of the Merger (the
"Surviving Corporation");

         WHEREAS, the Board of Directors of Target (i) has determined that the
Merger is in the best interests of Target and its stockholders (the "Target
Stockholders") and unanimously approved and adopted this Agreement and the
transactions contemplated hereby (the "Transactions") and (ii) has unanimously
recommended approval and adoption of this Agreement and approval of the Merger
by, and directed that this Agreement and the Merger be submitted to a vote of,
the Target Stockholders; and

         WHEREAS, the Boards of Directors of Parent and Parent Sub have
determined that the Merger is in the best interests of Parent and Parent Sub
and their stockholders and have unanimously approved and adopted this Agreement
and the Transactions.

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements herein contained, and intending to be legally bound
hereby, Parent, Parent Sub and Target hereby agree as follows:


                                   ARTICLE I

                                   THE MERGER

         SECTION 1.01. The Merger. Upon the terms and subject to the conditions
set forth in this Agreement and in accordance with Delaware Law, at the
Effective Time (as defined below), Parent Sub shall be merged with and into
Target.  As a result of the Merger, the outstanding shares of capital stock of
Parent Sub and Target shall be converted or canceled in the manner provided in
Article II of this Agreement, the separate corporate existence of Parent
<PAGE>   7
Sub shall cease, and Target will be the surviving corporation in the Merger and
shall become a subsidiary of Parent. The name of the Surviving Corporation
shall be DSC/Celcore, Inc.

         SECTION 1.02. Effective Time; Closing. As promptly as practicable on
or before December 4, 1997, and in no event later than the first business day
following the satisfaction or, if permissible, waiver of the conditions set
forth in Article VII (or such other date as may be agreed in writing by each of
the parties hereto), 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 (the "Secretary") in such
form as is required by, and executed in accordance with the relevant provisions
of, Delaware Law. The term "Effective Time" means the date and time of the
filing of the Certificate of Merger with the Secretary (or such later time as
may be agreed in writing by each of the parties hereto and specified in the
Certificate of Merger). Immediately prior to the filing of the Certificate of
Merger, a closing (the "Closing") will be held at the Dallas, Texas offices of
Baker & McKenzie (the "Closing Date") (or such other place as the parties may
agree).

         SECTION 1.03. Effect of the Merger. At the Effective Time, the effect
of the Merger shall be as provided in the applicable provisions of Delaware
Law. Without limiting the generality of the foregoing, and subject thereto, at
the Effective Time all the rights, privileges, powers and franchises (of a
public as well as of a private nature) of Target and Parent Sub and all
property (real, personal and mixed) of Target and Parent Sub and all debts due
to either Target or Parent Sub on any account, including subscriptions to
shares, and every other interest of or belonging to or due to each of Target
and Parent Sub shall vest in the Surviving Corporation, and all debts,
liabilities and duties of each of Target and Parent Sub shall become the debts,
liabilities, obligations and duties of the Surviving Corporation and may be
enforced against the Surviving Corporation to the same extent as if such debts,
liabilities, obligations and duties had been incurred or contracted by the
Surviving Corporation. The title to any real estate or any interest therein
vested, by deed or otherwise, in Target or Parent Sub shall not revert or in
any way become impaired by reason of the Merger, and all rights of creditors
and all liens upon any property of Target or Parent Sub shall be preserved
unimpaired following the Merger.

         SECTION 1.04. Certificate of Incorporation; Bylaws. (a) At the
Effective Time, the certificate of incorporation of Target, as in effect
immediately prior to the Effective Time, shall be amended as of the Effective
Time by operation of this Agreement and by virtue of the Merger without any
further action by the stockholders or directors of the Surviving Corporation to
read in its entirety as set forth in Exhibit A attached hereto.

                 (b)      At the Effective Time, the bylaws of Parent Sub, as
in effect immediately prior to the Effective Time, shall be the bylaws of the
Surviving Corporation until thereafter amended as provided by Delaware Law, the
certificate of incorporation of the Surviving Corporation and such bylaws.

<PAGE>   8
         SECTION 1.05. Directors and Officers. The directors of Parent Sub
immediately prior to the Effective Time shall be the initial directors of the
Surviving Corporation, each to hold office in accordance with the certificate
of incorporation and bylaws of the Surviving Corporation until a successor is
elected or appointed and has qualified or until the earliest of such director's
death, resignation, removal or disqualification, and the officers of Parent Sub
immediately prior to the Effective Time shall be the initial officers of the
Surviving Corporation, in each case until their respective successors are duly
elected or appointed and qualified, or as otherwise provided in the bylaws of
the Surviving Corporation.

                                   ARTICLE II

               CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES

         SECTION 2.01. Conversion of Securities. At the Effective Time, by
virtue of the Merger and without any action on the part of Parent Sub, Target
or the holders of any of the following securities:

                 (a)      Each share of common stock, $0.10 par value per share
("Target Common Stock"), of Target issued and outstanding immediately prior to
the Effective Time (other than Dissenting Shares (as defined below)) shall be
converted into the right to receive $8.00 (the "Merger Consideration") payable
to the holder thereof in cash, without any interest thereon, upon surrender of
the certificate representing such share in accordance with Section 2.02.

                 (b)      Each share of Series A Convertible Preferred Stock,
par value $0.10 per share ("Series A Preferred Stock"), Series B Convertible
Preferred Stock, par value $0.10 per share ("Series B Preferred Stock"), Series
C Convertible Preferred Stock, par value $0.10 per share ("Series C Preferred
Stock"), and Series D Convertible Preferred Stock, par value $0.10 per share
("Series D Preferred Stock"), of Target (collectively, the "Target Preferred
Stock") issued and outstanding immediately prior to the Effective Time (other
than Dissenting Shares) shall be converted into the right to receive the Merger
Consideration payable to the holder thereof in cash, without any interest
thereon, upon surrender of the certificate representing such share in
accordance with Section 2.02.

                 (c)      From and after the Effective Time, all shares of
Target Common Stock and Target Preferred Stock (together referred to as the
"Target Stock") (other than Dissenting Shares) shall no longer be outstanding
and shall automatically be canceled and retired and shall cease to exist, and
each certificate previously representing any such shares (other than Dissenting
Shares) shall thereafter represent the right to receive, subject to Section
2.02(h), the Merger Consideration to be paid in consideration therefor upon
surrender of such certificate in accordance with Section 2.02, without
interest. Subject to Section 2.02(h), certificates previously representing
shares of Target Stock (other than Dissenting Shares) shall be exchanged for
the Merger Consideration to be paid in consideration therefor upon the
surrender of such certificates in accordance with the provisions of Section
2.02, without interest.





                                       3
<PAGE>   9
                 (d)      Any shares of Target Stock held in the treasury of
Target and any shares of Target Stock owned by Parent or any direct or indirect
wholly owned subsidiary of Parent or of Target immediately prior to the
Effective Time shall be canceled and extinguished without any conversion
thereof and no payment shall be made with respect thereto.

                 (e)      Each share of common stock, par value $0.01 per
share, of Parent Sub ("Parent Sub Common Stock") issued and outstanding
immediately prior to the Effective Time shall be converted into and exchanged
for one newly and validly issued, fully paid and non-assessable share of common
stock of the Surviving Corporation.

         SECTION 2.02. Exchange of Certificates. (a) Exchange Agent. As of or
before the Effective Time, Parent shall deposit, or shall cause to be
deposited, with a bank or trust company organized under the laws of, and having
an office in, any state of the United States and designated by Parent (the
"Exchange Agent"), for the benefit of the holders of shares of Target Stock
and, for exchange through the Exchange Agent in accordance with this Article
II, cash in the aggregate amount required to make the cash payments specified
in Section 2.01, in respect of (i) the Target Common Stock issued and
outstanding at the Effective Time (other than Dissenting Shares and shares
canceled in accordance with Section 2.01(d)) and (ii) the Target Preferred
Stock issued and outstanding at the Effective Time (other than Dissenting
Shares and shares canceled in accordance with Section 2.01(d)), such sum being
hereinafter referred to as the "Exchange Fund". Subject to Section 2.02(h), the
Exchange Agent shall, pursuant to irrevocable instructions from Parent, deliver
cash contemplated to be paid pursuant to Section 2.01 out of the Exchange Fund.

                 (b)      Exchange Procedures. Promptly after the Effective
Time and subject to Section 2.02(h), Parent shall instruct the Exchange Agent
to mail to each holder of record of a certificate or certificates which
immediately prior to the Effective Time represented outstanding shares of
Target Stock (the "Certificates") (i) a letter of transmittal (which shall be
in customary form and specify that delivery shall be effected, and risk of loss
and title to the Certificates shall pass, only upon proper delivery of the
Certificates to the Exchange Agent) and (ii) instructions for use in effecting
the surrender of the Certificates in exchange for the consideration payable
therefor pursuant to Section 2.01. Upon surrender of a Certificate for
cancellation to the Exchange Agent together with such duly executed letter of
transmittal and such other documents as may be required pursuant to such
instructions, the holder of such Certificate shall be entitled to receive in
exchange therefor the Merger Consideration which such holder has the right to
receive in respect of the shares of Target Stock formerly represented by such
Certificates, less that portion of the Merger Consideration held in escrow
pursuant to Section 2.02(h) hereof. The surrendered Certificates shall then be
marked canceled. In addition, the holder of such Certificate subsequently may
receive cash in accordance with the escrow provisions of Article IX. In the
event of a transfer of ownership





                                       4
<PAGE>   10
of shares of Target Stock which is not registered in the transfer records of
Target, cash representing the consideration payable pursuant to Section 2.01
may be paid to a transferee if the Certificates representing such shares of
Target Stock are presented to the Exchange Agent, accompanied by all documents
required to evidence and effect such transfer and by evidence that any
applicable stock transfer taxes have been paid. Until surrendered as
contemplated by this Section 2.02, each Certificate shall be deemed at any time
after the Effective Time to represent only the right to receive upon such
surrender the consideration specified in this Article II. No interest will be
paid or will accrue on any cash payable to holders of Certificates pursuant to
the provisions of this Article II.

                 (c)      Investment of Exchange Fund. The Exchange Agent shall
invest any cash included in the Exchange Fund, as directed by Parent, on a
daily basis, provided that any such investment is guaranteed as to payment of
principal and interest by the federal government of the United States. Any
interest and other income resulting from such investments shall be paid to
Target Stockholders.

                 (d)      No Further Rights in Target Stock. All consideration
paid upon conversion of the shares of Target Stock in accordance with the terms
hereof shall be deemed to have been paid in full satisfaction of all rights
pertaining to such shares of Target Stock.

                 (e)      [Intentionally Omitted]

                 (f)      Termination of Exchange Fund. Any portion of the
Exchange Fund which remains undistributed to the holders of Target Stock for
one year after the Effective Time shall be delivered to Parent, upon demand,
and, subject to Section 2.02(g), any holders of Target Stock who have not
theretofore complied with this Article II shall thereafter look only to Parent
for the consideration therefor specified in this Article II.

                 (g)      No Liability. Neither Parent nor the Surviving
Corporation shall be liable to any Target Stockholders for any cash delivered
to a public official following termination of the Exchange Fund pursuant to any
applicable abandoned property, escheat or similar Law.

                 (h)      Escrow. Notwithstanding the foregoing, at the
Effective Time, five percent (5%) of the aggregate Merger Consideration payable
to Target Stockholders pursuant to Section 2.01 hereof as a result of the
Merger shall be segregated and deducted therefrom and established as an escrow
amount (the "Parent Escrow Amount"). In addition, at the Effective Time, three
hundred and thirty-three one-thousandths percent (.333%) of the aggregate
Merger Consideration payable to the Target Stockholders pursuant to Section
2.01 hereof as a result of the Merger shall be segregated and deducted
therefrom and established as an escrow amount (the "Representative Escrow
Amount"). The Parent Escrow Amount (together with five percent (5%) of any
shares of Parent Common Stock issued upon exercise of any Target Option between
the Effective Time and the Expiration Date) and the Representative Escrow





                                       5
<PAGE>   11
Amount (together with three hundred and thirty-three one-thousandths percent
(.333%) of any shares of Parent Common Stock issued upon exercise of any Target
Option between the Effective Time and the Expiration Date) shall be held in
accordance with and subject to the provisions of Article IX of this Agreement.
The Parent Escrow Amount (together with five percent (5%) of any shares of
Parent Common Stock issued upon exercise of any Target Option between the
Effective Time and the Expiration Date) shall be held as collateral for the
indemnification obligations of the Persons who were holders of Target Stock and
Target Options immediately prior to the Effective Time under Article IX of this
Agreement.  The Representative Escrow Amount (together with three hundred and
thirty-three one-thousandths percent (.333%) of any shares of Parent Common
Stock issued upon exercise of any Target Option between the Effective Time and
the Expiration Date) shall be held for the purpose of paying certain costs and
expenses of the Representative (as defined below) in performing his/her
obligations under Article IX.

                 (i)      Lost Certificates. If any Certificate shall have been
lost, stolen or destroyed, upon the making of an affidavit of that fact by the
Person claiming such Certificate to be lost, stolen or destroyed and, if
required by the Surviving Corporation, the posting by such Person of a bond in
such reasonable amount as the Surviving Corporation may direct as indemnity
against any claim that may be made against it with respect to such Certificate,
the Exchange Agent will issue in exchange for such lost, stolen or destroyed
Certificate the consideration payable (subject to Section 2.02(h)) in respect
thereof pursuant to this Agreement.

         SECTION 2.03. Stock Transfer Books. At the Effective Time, the stock
transfer books of Target shall be closed and there shall be no further
registration of transfers of shares of Target Stock thereafter on the records
of Target.  On or after the Effective Time, any Certificates presented to the
Exchange Agent or Parent for any reason shall be canceled and exchanged into
the consideration therefor specified in this Article II in accordance with the
terms of this Agreement.

         SECTION 2.04. Stock Options. (a) All options (the "Target Options")
under the Target's 1995 Stock Option Plan and 1996 Stock Incentive Plan
(together, the "Target Stock Option Plan"), outstanding at the Effective Time,
whether or not exercisable, whether or not vested, and whether or not
performance-based, shall remain outstanding following the Effective Time,
except that, in accordance with the amendments to the Target Options for
Messrs. Berger, Foley, Gonzalez and Rosen, each of which is dated January 30,
1997 under the Target Stock Option Plan, the Target Options for Messrs.
Berger, Foley, Gonzales and Rosen shall be fully exercisable immediately prior
to the Effective Time. At the Effective Time, the Target Options shall, by
virtue of the Merger and without any further action on the part of the holders
thereof or the Target, be assumed by Parent. From and after the Effective Time,
all references to the Target in the Target Stock Option Plan and the applicable
stock option agreements issued thereunder shall be deemed to refer to Parent,
which shall have assumed the Target Stock Option Plan as of the Effective Time
by virtue of this Agreement





                                       6
<PAGE>   12
and without any further action. Each Target Option assumed by Parent (each a
"Substitute Option") shall be exercisable upon the same terms and conditions as
under the applicable Target Stock Option Plan and the applicable option
agreement issued thereunder, except that (i) each such Target Option shall be
exercisable for, and represent the right to acquire, that whole number of
shares of Parent Common Stock (rounded up or down to the nearest whole share)
equal to the number of shares of Target Common Stock subject to such Target
Option multiplied by the Exchange Ratio (as defined below); (ii) the option
price per share of Parent Common Stock shall be an amount equal to the option
price per share of Target Common Stock subject to such Target Option in effect
immediately prior to the Effective Time divided by the Exchange Ratio (the
option price per share, as so determined, being rounded upward to the nearest
full cent); and (iii) with respect to any Target Option which is
performance-based, the performance targets shall be adjusted following the
Effective Time in the good faith judgment of the Board of Directors of Parent
to fairly reflect the impact, if any, of the Transactions; and (iv) in the case
of any Substitute Option that remains unexercised as of the termination of the
Escrow Period (as defined below), the number of shares of Parent Common Stock
issuable upon the exercise of such Substitute Options shall be reduced in
proportion to any reduction in the number of shares of Parent Common Stock
received by holders of the Substitute Options assumed by Parent which are
exercised prior to the Expiration Date as a result of any distribution made to
Parent pursuant to Article IX of this Agreement. No payment shall be made for
fractional interests of Parent Common Stock represented by the Substitute
Options.

                 (b)      As soon as practicable after the Effective Time,
Parent shall deliver to each holder of an outstanding Target Option an
appropriate notice setting forth such holder's rights pursuant thereto and such
Target Option shall continue in effect on the same terms and conditions
(including any antidilution provisions, and subject to the adjustments required
by this Section 2.04 after giving effect to the Merger). Parent shall comply
with the terms of all such Target Options and ensure, to the extent required
by, and subject to the provisions of, the Target Stock Option Plan that Target
Options which qualified as incentive stock options under Section 422 of the
Code (as defined below) prior to the Effective Time continue to qualify as
incentive stock options after the Effective Time. Parent shall take all
corporate action necessary to reserve for issuance a sufficient number of
shares of Parent Common Stock for delivery upon exercise of Substitute Options
pursuant to the terms set forth in this Section 2.04. Following the Effective
Time, the shares of Parent Common Stock subject to Target Options will be
covered by an effective registration statement on Form S-8 (or any successor
form) or another appropriate form with the Securities and Exchange Commission
("SEC") and Parent shall use its Best Efforts to maintain the effectiveness of
such registration statement or registration statements for so long as
Substitute Options remain outstanding.

                 (c)      If between the date of this Agreement and the
Effective Time, the outstanding shares of Parent Common Stock, Target Common
Stock or Target Preferred Stock shall have been changed into a different number
of shares or a different class, by reason of any stock dividend, subdivision,
reclassification, recapitalization, split, combination or exchange





                                       7
<PAGE>   13
of shares, the Exchange Ratio shall be correspondingly adjusted to reflect such
stock dividend, subdivision, reclassification, recapitalization, split,
combination or exchange of shares.

         SECTION 2.05. Escrow Approval. By adopting and approving this
Agreement, the Target Stockholders, except in respect of Dissenting Shares,
approve the Parent Escrow Agreement (as defined below) and the Representative
Escrow Agreement (as defined below), the appointment of the Escrow Agent to act

Representative Escrow Agreement and this Agreement and the appointment of the
Representative (as defined below) to act on behalf of the Target Stockholders
and the holders of the Target Options under the terms of the Parent Escrow
Agreement and the Representative Escrow Agreement and this Agreement. If the
Representative ceases to be the Representative for any reason, he will be
replaced in accordance with the terms of the Parent Escrow Agreement.

         SECTION 2.06. Appraisal Rights. Any issued and outstanding share of
Target Stock which has not been voted for the Merger and with respect to which
appraisal will have been properly demanded in accordance with Section 262 of
the Delaware Law ("Dissenting Shares") will not be converted into the right to
receive the consideration described in Section 2.01, and the holders thereof
will have only such rights as are provided in Section 262 of the Delaware Law,
unless and until the Target Stockholder withdraws such holder's demand for such
appraisal in accordance with the Delaware Law or otherwise loses such holder's
right to such appraisal. If a Target Stockholder withdraws such holder's demand
for appraisal or will otherwise lose the right to such appraisal, then, as of
the Effective Time or the occurrence of such event, whichever last occurs, such
holder's shares of Target Stock will cease to be Dissenting Shares and will be
converted into the consideration described in Section 2.01. Prior to the
Effective Time, Target will give Parent prompt notice of any written demands
for appraisal or withdrawals of demands for appraisal received by Target and,
except with the prior written consent of Parent, will not settle or offer to
settle any such demands.

                 Except as set forth in the disclosure schedule delivered by
Target and signed by Target, Parent and Parent Sub for identification prior to
the execution and delivery of this Agreement (the "Target Disclosure
Schedule"), which shall identify exceptions by specific section references, the

         SECTION 3.01. Corporate Organization and Qualification; Subsidiaries.
Each of Target and Celcore International, Inc. (Delaware), a Delaware
corporation, and Celcore International, Inc. (Mauritius), a Republic of
Mauritius corporation (the "Target Subsidiaries"), is a corporation duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation and has the requisite corporate power and
authority to own,





                                       8
<PAGE>   14
lease and operate its properties and to carry on its business as it is now
being conducted. Each of Target and the Target Subsidiaries is duly qualified
or licensed as a foreign corporation to do business, and is in good standing,
in each jurisdiction where the character of the properties owned, leased or
operated by it or the nature of its business makes such qualification or
licensing necessary, except for such failures to be so qualified or licensed
and in good standing that would not, individually or in the aggregate, have a
Material Adverse Effect. As used in this Agreement, the term "Material Adverse
Effect" means with respect to any Person, any change or effect that is, or is
reasonably likely to be, materially adverse to the financial condition,
business or results of operations of such Person and its subsidiaries, taken as
a whole. Other than the Target Subsidiaries, Target does not have any
subsidiaries. Neither Target nor either Target Subsidiary owns directly or
indirectly any voting equity or similar voting interest in, or any interest
convertible into or exchangeable or exercisable for, any voting equity or
similar voting interest in, any corporation, partnership, joint venture or
other business association or entity. Target is not, and has not been within
the two years immediately preceding the date hereof, a subsidiary or division
of another corporation, nor has Target within such time owned, directly or
indirectly, any shares of Parent Common Stock.

         SECTION 3.02. Certificate of Incorporation and Bylaws. The Target has
heretofore furnished or made available to Parent a complete and correct copy of
its and the Target Subsidiaries' certificates of incorporation and bylaws, each
as amended to date. Neither the Target nor either of the Target Subsidiaries is
in violation of any provision of its certificate of incorporation or bylaws.

         SECTION 3.03. Capitalization. The authorized capital stock of the
Target consists of 50,000,000 shares of Target Common Stock and 14,000,000
shares of Target Preferred Stock, consisting of 4,500,000 shares of Series A
Preferred Stock, 3,000,000 shares of Series B Preferred Stock, 4,000,000 shares
of Series C Preferred Stock and 2,500,000 shares of Series D Preferred Stock.
As of the date of this Agreement, (a) 5,591,250 shares of Target Common Stock
and (b) 4,500,000, 3,000,000, 3,038,045.66 and 2,004,227 shares of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series
D Preferred Stock, respectively (a total of 12,542,273 shares of Target
Preferred Stock), were issued and outstanding, all of which are validly issued,
fully paid and nonassessable and not subject to preemptive rights, and (c)
2,460,250 shares of Target Common Stock are issuable pursuant to outstanding
Target Options. Each share of Target Preferred Stock is convertible into one
share of Target Common Stock. All of the issued and outstanding shares of
capital stock of the Target Subsidiaries are held by Target and are validly
issued, fully paid and nonassessable and not subject to preemptive rights. No
shares of capital stock of the Target have been acquired by the Target that are
subject to outstanding pledges by the Target to secure the future payment of
some or all of the purchase price for such shares. Other than the Target
Options, as of the date of this Agreement, there are no options, warrants or
other rights, agreements, arrangements or commitments of any character relating
to the issued or unissued capital stock of the Target obligating the Target to
issue or sell any shares of capital stock of, or other equity interests in, the
Target or the Target Subsidiaries. Between August 31, 1997 and the date of





                                       9
<PAGE>   15
this Agreement, no shares of Target Common Stock have been issued by the
Target, except pursuant to the exercise of the stock options, stock incentive
rights and warrants described above that were outstanding on August 31, 1997,
in each case in accordance with their respective terms. All shares of Target
Common Stock subject to issuance as aforesaid, upon issuance on the terms and
conditions specified in the instruments pursuant to which they are issuable,
will be duly authorized, validly issued, fully paid and nonassessable. Other
than as set forth in Target's certificate of incorporation (including the
Target Preferred Stock certificates of designation, each a "Certificate of
Designation"), there are no outstanding contractual obligations of the Target
to repurchase, redeem or otherwise acquire any shares of Target Stock. Target
has not made any distributions to any Target Stockholders or participated in or
effected any issuance, exchange or retirement of shares of Target Common Stock,
or otherwise changed the equity interests of Target Stockholders, in
contemplation of effecting the Merger within the two years immediately
preceding the date hereof.  Target has not reacquired during the two years
immediately preceding the date of this Agreement any shares of Target Common
Stock.

         SECTION 3.04. Authority Relative to This Agreement. The Target has all
necessary corporate power and authority to execute and deliver this Agreement

execution and delivery of this Agreement by the Target and the consummation by
the Target of the Transactions (including the Amendments (as defined in Section
3.05)) have been duly and validly authorized by all necessary corporate action
and no other corporate proceedings on the part of the Target are necessary to
authorize this Agreement or to consummate the Transactions (other than, with
respect to the Merger, the approval and adoption of this Agreement and the
Amendments by the Target Stockholders as described in Section 3.17 and
recordation of an appropriate Certificate of Merger with the Secretary as
required by Delaware Law). This Agreement has been duly and validly executed
and delivered by the Target and, assuming the due authorization, execution and
delivery of this Agreement by Parent and Parent Sub, constitutes a legal, valid
and binding obligation of the Target, enforceable against the Target in
accordance with its terms.

         SECTION 3.05. No Conflict; Required Filings and Consents. (a) The
execution and delivery of this Agreement by the Target do not, and the
performance of this Agreement by the Target will not, subject to, (x) with
respect to the Merger, obtaining the requisite approval and adoption of the
Merger and the Amendments by the Target Stockholders in accordance with its
certificate of incorporation (including its Certificates of Designations), this
Agreement and Delaware Law, (y) the filing of certificates of amendment
relating to the amendments to the Target's certificate of incorporation
(including its Certificates of Designations) with the Secretary of State of
Delaware, which amendments shall remove the thirty (30) day period for notice
required under Article Fourth, Section E(iv)(e) of the certificate of
incorporation of Target and Section D(iv)(e) of each of the Certificates of
Designations (the "Amendments") and (z) obtaining any necessary Consents from

Authorities and making the filings described in Section 3.05(b) and Section
3.05(b) of the Target Disclosure Schedule, (i) subject to the adoption of the
Amendments, conflict with or violate the certificate of incorporation or bylaws
of the Target or the Target Subsidiaries, (ii) conflict with or violate any Law
applicable to the Target or the Target Subsidiaries or by which any property or
asset of the Target or the Target Subsidiaries is bound or affected, or (iii)
except as specified in Section 3.20 of the Target Disclosure Schedule, result
in any Breach of or constitute a default (or an event which with notice or
lapse of time or both would become a default) under, or give to others any
right of termination, amendment, acceleration or cancellation of, or result in
the creation of a lien or other encumbrance on any property or asset of the
Target or the Target Subsidiaries or require the Consent of any third party
pursuant to, any note, bond, mortgage, indenture, Contract, license, permit,
franchise or other instrument or obligation to which the Target or the Target
Subsidiaries is a party other than with respect to breaches or defaults which
would not constitute a Material Adverse Effect.

                 (b)      The execution and delivery of this Agreement by the
Target do not, and the performance of this Agreement and the Transactions
contemplated hereby by the Target will not, require any Consent or permit of,
or filing with or notification to, any United States (federal, state or local)
or foreign government, or governmental, regulatory or administrative authority,
agency or commission or court of competent jurisdiction ("Governmental
Authority"), except (i) for applicable requirements, if any, of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), the Securities Act of
1933, as amended (the "Securities Act"), state securities or "blue sky" laws
("Blue Sky Laws"), the pre-merger notification requirements of the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the rules

required by Delaware Law or (ii) as specified in Section 3.05(b) of the Target
Disclosure Schedule.

Subsidiaries is in possession of all Governmental Authorizations necessary for
each of the Target and the Target Subsidiaries to own, lease and operate its
properties or to carry on its business as it is now being conducted (the
"Target Permits") and, as of the date hereof, no suspension or cancellation of
any of the Target Permits is pending or, to the Knowledge of the Target,
Threatened, except in each case for such Governmental Authorizations, the
absence of which would not have a Material Adverse Effect.  Neither the Target
nor the Target Subsidiaries is in conflict with, or in default or violation of,
(i) any Law applicable to it or by which any property or asset of it is bound
or affected, or (ii) any Target Permit, other than a conflict with, or default
or violation of, such Laws or Target Permits that would not have a Material
Adverse Effect on Target.

         SECTION 3.07. Financial Statements; Books and Records. (a) Target has
delivered to Parent: (i) (A) audited balance sheets of the Target and
statements of stockholders' (deficit) equity as at December 31, 1994, 1995 and

respective dates of and for the periods referred to in such Financial
Statements, all in accordance with GAAP, except that the unaudited financial
statements referred to in clause (ii) may be subject to normal year-end
adjustments. The Financial Statements reflect the consistent application of
such accounting principles throughout the periods involved. No financial
statements of any Person other than the Target are required by GAAP to be
included in the Financial Statements of the Target.

                 (b)      The books of account, minute books, stock record
books, and other records of the Target and each Target Subsidiary, all of which
have been made available to Parent, are complete and correct in all material
respects and have been maintained in accordance with sound business practices,
including the maintenance of an adequate system of internal controls. The
minute books of the Target and each Target Subsidiary contain accurate and
complete records of all meetings held of, and corporate action taken by, the

Directors of the Target and each Target Subsidiary, as appropriate, and no

minute books. At the Closing, all of those books and records will be in the
possession of the Target.

                          Affiliate has any known liability to the Internal

                          the Code as to each Target Plan have been timely
                          filed, and all material notices and disclosures to
                          participants required by either ERISA or the Code
                          have been timely provided.

                 Knowledge, no event has occurred or circumstance exists that
                 will or could give rise to disqualification or loss of
                 tax-exempt status of any such Plan or trust.  Each Qualified

                 liability with respect to any Title IV Plan.

                          (x)     Neither the Target nor any ERISA Affiliate
                 has ever established, maintained, or contributed to or
                 otherwise participated in, or had an obligation to maintain,
                 contribute to, or otherwise participate in, any Multiemployer
                 Plan.

                          (xi)    Neither the Target nor any ERISA Affiliate
                 has any liability (including current or potential withdrawal
                 liability) with respect to any Multiemployer Plan.

                          (xii)   Neither the Target nor any ERISA Affiliate
                 has ever established, maintained or contributed to any VEBA,

                 liability with respect to any VEBA.

                 Section 601 et seq. and Code Section 4980B, neither the Target
                 nor any ERISA Affiliate provides health or welfare benefits
                 for any retired or former employee or is obligated to provide
                 health or welfare benefits to any active employee following
                 such employee's retirement or other termination of service.

                          (xiv)   The Target and each ERISA Affiliate has
                 complied in all material respects with the provisions of ERISA
                 Section 601 et seq. and Code Section 4980B and has also
                 complied in all material respects with the applicable
                 provisions of ERISA Section 701 et seq. and Subtitle K of the
                 Code.

                 any Person will be non-deductible to the Target or subject to
                 tax under Code Section 280G or Section 4999; nor will the
                 Target be required to "gross up" or otherwise compensate any
                 such Person because of the imposition of any excise tax on a
                 payment to such Person.

                          (xvi)   The consummation of the Transactions will not
                 result in the payment, vesting, or acceleration of any

                          (i)     With respect to each Trade Secret, the

                 accurate in all material respects.

                          (ii)    The Target has taken all reasonable
                 precautions to protect the secrecy, confidentiality and value
                 of its Trade Secrets.

                          (iii)   The Target has good title and an absolute
                 (but not necessarily exclusive) right to use the Trade
                 Secrets. The Trade Secrets have not been made public, and have
                 not been used, divulged or appropriated either for the benefit
                 of any Person (other than the Target) or to the detriment of
                 the Target. No Trade Secret is subject to any adverse claim or

has been received (other than amounts being contested in good faith by

aggregate, have a Material Adverse Effect. Neither the Internal Revenue Service
nor any other taxing authority has asserted any claim for taxes, or to the best
Knowledge of the Target, is Threatening to assert any claims for taxes; which
claims, individually or in the aggregate, could have a Material Adverse Effect.

collected and paid over to the appropriate Governmental Authorities (or is
properly holding for such payment) all taxes required by Law to be withheld or

aggregate, have a Material Adverse Effect. The Target has not made an election
under Section 341(f) of the Code. There are no liens for taxes upon the assets

similar provision and the consummation of the Transactions will not (either
alone or upon the occurrence of any additional acts or events) result in any
payment (whether of severance pay or otherwise) becoming due from the Target or
the Target Subsidiaries to any Person.

         SECTION 3.28. Payments Resulting from Mergers. Except as set forth in
Section 3.28 of the Target Disclosure Schedule, copies of which have been
delivered to Parent, neither the consummation nor announcement of any of the
Transactions will result in any (i) material payment (whether of severance pay
or otherwise) becoming due from Target or the Target Subsidiaries to any
director, officer, employee or former employee thereof under (i) any
management, employment, deferred compensation, severance (including any
payment, right or benefit resulting from a change in control), bonus or other
contract for personal services with any officer, director or employee or any
plan, agreement or understanding similar to any of the foregoing, or any "rabbi
trust" or similar arrangement, or (ii) material benefit under any Plan being
established or becoming accelerated, vested or payable.

         SECTION 3.29. State Takeover Statutes. The Board of Directors of
Target has approved the terms of this Agreement and the Merger and the other
Transactions, and such approval is sufficient to render inapplicable to the
Merger and the other Transactions the provisions of Section 203 of the Delaware
Law. To Target's Knowledge, no other state takeover statute or similar statute
or regulation applies or purports to apply to the Merger or the other
Transactions and no provision of the certificate of incorporation, bylaws or
other governing instruments of Target (including the Certificates of
Designations) or either of the Target Subsidiaries would, directly or
indirectly, restrict or impair the ability of Parent to vote, or otherwise to
exercise the rights of a stockholder with respect to, shares of Target and the
Target Subsidiaries that may be acquired or controlled by Parent.

                                   ARTICLE IV

                    REPRESENTATIONS AND WARRANTIES OF PARENT
                                 AND PARENT SUB

         Except as set forth in the disclosure schedule delivered by Parent and
Parent Sub to the Target and signed by the Target, Parent and Parent Sub for
identification prior to the execution and delivery of this Agreement (the
"Parent Disclosure Schedule"), which shall identify exceptions by specific
section references, Parent and Parent Sub hereby, jointly and severally,
represent and warrant to the Target that:

         SECTION 4.01. Corporate Organization and Qualification. Each of Parent
and Parent Sub is a corporation duly organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation and has the
requisite corporate power and authority to own, lease and operate its
properties and to carry on its business as it is now being conducted. Each of
Parent and Parent Sub is duly qualified or licensed as a foreign corporation to
do business, and is in good standing in each jurisdiction where the character
of the properties owned, leased or operated by it or the nature of its business
makes such qualification or licensing necessary, except for such failures to be
so qualified or licensed and in good standing as would not, individually or in
the aggregate, have a Material Adverse Effect. Parent is not, and has not been
within the two years immediately preceding the date of this Agreement, a
subsidiary or





                                       30
<PAGE>   36
division of another corporation, nor has Parent within such time owned,
directly or indirectly, any shares of Target Common Stock.

         SECTION 4.02. Certificate of Incorporation and Bylaws. Parent has
heretofore furnished or made available to the Target a complete and correct
copy of the certificates of incorporation and bylaws of each of Parent and
Parent Sub, each as amended to date. Neither Parent nor Parent Sub is in
violation of any provision of its certificate of incorporation or bylaws.

         SECTION 4.03. Capitalization. As of the date of this Agreement, the
authorized capital stock of Parent consists of 500,000,000 shares of Parent
Common Stock, $0.01 par value, and 5,000,000 shares of preferred stock, $1.00
par value ("Parent Preferred Stock"). As of June 30, 1997, (a) 117,388,254
shares of Parent Common Stock were issued and outstanding, all of which were
validly issued, fully paid and nonassessable, (b) 4,988,958 shares of Parent
Common Stock were held in the treasury of Parent, (c) 9,414,142 shares of
Parent Common Stock were reserved for future issuance pursuant to outstanding
stock options or stock incentive rights granted pursuant to Parent's stock
option and restricted stock plans, and (d) no shares of Parent Preferred Stock
were outstanding. The authorized capital stock of Parent Sub consists of 1,000
shares of Parent Sub Common Stock, of which, as of the date of this Agreement,
one (1) share is issued and outstanding and held by Parent.

         SECTION 4.04. Authority Relative to This Agreement. Each of Parent and
Parent Sub has all necessary corporate power and authority to execute and
deliver this Agreement and, with respect to the Merger, to perform its
obligations hereunder and to consummate the Transactions. The execution and
delivery of this Agreement by Parent and Parent Sub and the consummation by
Parent and Parent Sub of the Transactions have been duly and validly authorized
by all necessary corporate action and no other corporate proceedings on the
part of Parent or Parent Sub are necessary to authorize this Agreement or to
consummate the Transactions (other than, with respect to the Merger, the filing
and recordation of the appropriate Certificate of Merger with the Secretary as
required by Delaware Law). This Agreement has been duly and validly executed
and delivered by Parent and Parent Sub and, assuming the due authorization,
execution and delivery of this Agreement by the Target, constitutes a legal,
valid and binding obligation of each of Parent and Parent Sub enforceable
against each of Parent and Parent Sub in accordance with its terms.

         SECTION 4.05. No Conflict; Required Filings and Consents. (a) The
execution and delivery of this Agreement by Parent and Parent Sub do not, and
the performance of this Agreement by Parent and Parent Sub will not, subject
to, obtaining the Consents and permits and making the filings described in
Section 4.05(b) and Section 4.05(b) of the Parent Disclosure Schedule, (i)
conflict with or violate the certificate of incorporation of either Parent or
Parent Sub, (ii) conflict with or violate any Law applicable to Parent or
Parent Sub or by which any property or asset of any of them is bound or
affected, or (iii) result in any Breach of or constitute a default (or an event
which with notice or lapse of time or both would become





                                       31

a default) under, or give to others any rights of termination, amendment,
acceleration or cancellation of, or result in the creation of a lien or other
encumbrance on any property or asset of Parent or Parent Sub or require the
Consent of any third party pursuant to, any note, bond, mortgage, indenture,
Contract, license, permit, franchise or other instrument to which Parent or
Parent Sub is a party or by which Parent or Parent Sub or any property or asset
of any of them is bound or affected, except for any such conflicts, violations,
breaches, defaults or other occurrences which would not, individually or in the
aggregate, have a Material Adverse Effect on Parent or prevent Parent or Parent
Sub from performing their respective obligations under this Agreement and
consummating the Transactions.

                 (b)      The execution and delivery of this Agreement by
Parent and Parent Sub do not, and the performance of this Agreement by Parent
and Parent Sub will not, require any Consent or filing with or notification to,
any Governmental Authority, except (i) for applicable requirements, if any, of
the Exchange Act, the Securities Act, Blue Sky Laws, the HSR Act and filing and
recordation of an appropriate Certificate of Merger with the Secretary as
required by Delaware Law, (ii) as specified in Section 4.05(b) of the Parent
Disclosure Schedule, and (iii) where failure to obtain such consents,
approvals, authorizations or permits, or to make such filings or notifications,
would not have a Material Adverse Effect on Parent and would not prevent or
delay consummation of the Transactions, or otherwise prevent Parent or Parent
Sub from performing their respective obligations under this Agreement.

         SECTION 4.06. Ownership of Parent Sub; No Prior Activities. (a) Parent
Sub was formed solely for the purpose of engaging in the Transactions
contemplated by this Agreement.

                 (b)      As of the date hereof and the Effective Time, except
for obligations or liabilities incurred in connection with its incorporation or
organization and the Transactions and except for this Agreement and any other
agreements or arrangements contemplated by this Agreement, Parent Sub has not
and will not have incurred, directly or indirectly, through any subsidiary or
affiliate, any obligations or liabilities or engaged in any business activities
of any type or kind whatsoever or entered into any agreements or arrangements
with any Person.

                 to obtain any third party Consent described in subsection
                 (b)(i) above, it shall use its Best Efforts, and shall take
                 any such actions reasonably requested by the other party, to

                 respective subsidiaries, and their respective businesses
                 resulting, or which could reasonably be expected to result
                 after the Effective Time, from the failure to obtain such
                 Consent.

Time, each party shall promptly notify the other party of any pending, or to

Parent or Parent Sub (including the Surviving Corporation) after the Effective
Time.

other than Parent or Parent Sub; provided, however, that if at any time prior
to the receipt of the votes of the Target Stockholders necessary to approve the
Merger pursuant to Section 6.02, the Board of Directors of Target determines in
good faith, based on the written advice of outside counsel, that it is
necessary to do so in order to comply with its fiduciary duties to the Target
Stockholders under Delaware Law, Target (and its Agents) may, in response to an
unsolicited Takeover Proposal (a "Superior Proposal") that involves
consideration to the Target Stockholders with a value that Target's Board of
Directors reasonably believes, after receiving written advice from Target
Banker, is superior to the

activity, discussion or negotiation with any parties conducted heretofore by
Target with respect to any Takeover Proposal existing on the date hereof.
Without limiting the foregoing, it is understood that any violation of the
restrictions set forth in the preceding sentence by Target, the Target
Subsidiaries or any Agent of Target or the Target Subsidiaries, whether or not
such Person is purporting to act on behalf of Target or the Target Subsidiaries
or otherwise, shall be deemed to be a breach of this Section 6.05(a) by Target.

and in writing of any request for information or of any Takeover Proposal or
any inquiry with respect to or which could reasonably be expected to lead to
any Takeover Proposal, the identity of the Person making any such request,
Takeover Proposal or inquiry and all the terms and conditions thereof. Target
will keep Parent fully informed of the status and details (including amendments
or proposed amendments) of any such request, Takeover Proposal or inquiry.

                 (c)      Neither the Board of Directors of Target nor any
committee thereof shall (x) withdraw or modify, or propose to withdraw or
modify, in a manner adverse to Parent, the approval (including, without
limitation, either the Board of Directors' or any committee's resolution
thereof providing for such approval) or recommendation by such Board of
Directors or such committee of this Agreement or the Merger or (y) approve or
recommend, or propose to approve or recommend, any Takeover Proposal, except in
connection with a Superior Proposal and then only at or after the termination
of this Agreement pursuant to Section 8.01(f).

         SECTION 6.06. Obligations of Parent Sub. Parent shall take all action
necessary to cause Parent Sub to perform its obligations under this Agreement
and to consummate the Merger on the terms and subject to conditions set forth

shall consult with the other before issuing any press release or otherwise
making any public statements with respect to this Agreement or any Transaction
and shall not issue any such press release or make any such public statement
without the prior written consent of the other party, except as may be required
by Law, and (b) prior to the Effective Time, Target will not issue any other
press release or otherwise make any public statements regarding its business
without the prior written consent of Parent, which consent shall not be
unreasonably withheld.

after the date hereof, to offer to and endeavor to enter into employment
agreements at the Effective Time with the officers and employees of Target on
terms reasonably satisfactory to Parent.

party to this Agreement agrees, subject to the terms and conditions of this
Agreement, to take such reasonable actions and to execute and deliver such
documents as may be necessary to effectuate the purposes of this Agreement at
the earliest practicable time.

         SECTION 6.10. Registration on Form S-8. Parent shall prepare and file
with the SEC, and shall use its Best Efforts to cause to become effective, a

periods (such balance sheets, and related statements being collectively
referred to in this Agreement as the "Unaudited Monthly Statements"). The
Unaudited Monthly Statements will be prepared from the books and records of
Target and will fairly present, in all material respects, the financial
position of Target and the results of its operations and its cash flows as of
and for the respective time periods in accordance with internal Target
accounting methods and standards currently used.

         SECTION 6.13. [Intentionally Omitted]

         SECTION 6.14. Update Disclosure; Breaches. From and after the date of
this Agreement until the Effective Time, each party hereto shall promptly
notify the other party hereto by written update to its Disclosure Schedule of
(i) the occurrence, or non-occurrence, of any event the occurrence, or
non-occurrence, of which would, or would reasonably be likely to, cause any
condition to the obligations of any party to effect the Merger and the other
Transactions contemplated by this Agreement not to be satisfied, or (ii) the
failure of Target or Parent, as the case may be, to comply with or satisfy in
any material respect any covenant, condition or agreement to be complied with
or satisfied by it pursuant to this Agreement which would, or would reasonably
be likely to, result in any condition to the obligations of any party to effect
the Merger and the other Transactions contemplated by this Agreement not to be
satisfied. No disclosure by any party pursuant to this Section 6.14 will be
deemed to amend or supplement either the Target Disclosure Schedule or the
Parent Disclosure Schedule or prevent or cure any inaccuracy or Breach of
representation or warranty, or Breach of any covenant or obligation hereunder.

                                  TERMINATION

         SECTION 8.01. Termination. This Agreement may be terminated and the
Merger and the other Transactions may be abandoned at any time prior to the
Effective Time, notwithstanding any requisite approval and adoption of this
Agreement and the Transactions, as follows:

                 (a)      by mutual written consent duly authorized by the
Boards of Directors of each of Parent, Parent Sub and Target;

                 (b)      by either Parent or Target, if either (i) the
Effective Time shall not have occurred on or before January 31, 1998 (or such
later date as shall have been agreed to in writing by Parent and Target);
provided, however, that the right to terminate this Agreement under this
Section 8.01(b) shall not be available to any party whose failure to fulfill
any obligation under this Agreement has been the cause of, or resulted in, the
failure of the Effective Time to occur on or before such date; or (ii) there
shall be any Order which is final and nonappealable preventing the consummation
of the Merger, except if the party relying on such Order has not complied with
its obligations under Section 6.03(a);

                 (c)      by either Parent or Target, if (i) the Target
Stockholders shall have failed to approve and adopt this Agreement, the Merger
and other Transactions at a meeting duly convened therefor, or (ii) the
condition precedent under Section 7.02(i) has not been fulfilled;

                 (d)      by Parent, upon a Breach of any representation,
warranty, covenant or agreement on the part of Target set forth in this
Agreement, or if any representation or warranty of Target is not true and
correct in all material respects (except that where any statement in a
representation or warranty expressly includes a standard of materiality, such





                                       43
<PAGE>   49
statement shall be true and correct), in either case such that the conditions
set forth in Sections 7.02(a) and (b) would not be satisfied, other than a
Breach that would not have a Material Adverse Effect on Target (a "Terminating
Target Breach"); provided, however, that, if such Terminating Target Breach is
curable by the Target through the exercise of its Best Efforts and for so long
as the Target continues to exercise such Best Efforts, Parent may not terminate
this Agreement under Section 8.01(d); or

                 (e)      by Target, upon Breach of any representation,
warranty, covenant or agreement on the part of Parent set forth in this
Agreement, or if any representation or warranty of Parent is not true and
correct in all material respects (except that where any statement in a
representation or warranty expressly includes a standard of materiality, such
statement shall be true and correct), in either case such that the conditions
set forth in Sections 7.03(a) and (b) would not be satisfied, other than a
Breach that would not have a Material Adverse Effect on Parent ("Terminating
Parent Breach"); provided, however, that, if such Terminating Parent Breach is
curable by Parent through the exercise of its Best Efforts and for so long as
Parent continues to exercise such Best Efforts, the Target may not terminate
this Agreement under this Section 8.01(e); or

                 (f)      by Parent, if the Board of Directors of Target shall
(i) withdraw its recommendation to the Target Stockholders to approve the
Merger, or (ii) have recommended to the Target Stockholders any Business
Combination Transaction (as defined below) or resolved to do so.

         SECTION 8.02. Fees and Expenses. (a) Target shall pay Parent a fee (a
"Transaction Fee") of $5,000,000, less any Specified Expenses (as defined
below) previously paid, if this Agreement is terminated pursuant to (i) Section
8.01(c) and any Business Combination Transaction is thereafter consummated
within twelve (12) months of such termination or (ii) Section 8.01(f). As used
herein, the term "Business Combination Transaction" shall mean any of the
following involving Target: (A) any merger, consolidation, share exchange,
business combination or other similar transaction (other than the
Transactions); (B) any sale, lease, exchange, transfer or other disposition
(other than a pledge or mortgage) of 25% or more of the assets of Target and
the Target Subsidiaries, taken as a whole, in a single transaction or series of
transactions; or (C) the acquisition by a Person or any "group" (as such term
is defined under Section 13(d) of the Exchange Act and the rules and
regulations thereunder) of beneficial ownership of 33 1/3% or more of the
shares of Target Stock, considered as a whole, whether by tender offer,
exchange offer or otherwise.

                 (b)      Parent shall be entitled to receive its Specified
Expenses (but not the Transaction Fee) up to $1,000,000 in immediately
available funds in the event that this Agreement is terminated pursuant to
Section 8.01(d) and one-half (1/2) of its Specified Expenses up to $500,000 in
immediately available funds in the event the Agreement is terminated pursuant
to Section 8.01(c). Target shall be entitled to receive its Specified





                                       44
<PAGE>   50
Expenses up to $500,000 in immediately available funds in the event that this
Agreement is terminated pursuant to Section 8.01(e).

                 (c)      In the event of termination of this Agreement and the
abandonment of the Merger pursuant to Section 8.01, all obligations of the
parties hereto shall terminate except the obligations of the parties pursuant
to this Section 8.02 and Sections 6.07, 10.01, 10.02, 10.03, 10.05, 10.08,
10.12, 10.13, 10.14 and 10.15 and pursuant to the Confidentiality Agreement. No
termination of this Agreement pursuant to Section 8.01(d) or 8.01(e) shall
prejudice the ability of a non-breaching party from seeking Damages to which
such party would otherwise be entitled from any other party for any breach of
this Agreement including without limitation, attorneys' fees and the right to
pursue any remedy at law or in equity. Notwithstanding the foregoing, if Parent
is required to file suit to seek the Transaction Fee or either Parent or the
Target is required to file suit to seek its Specified Expenses, and such party
ultimately succeeds on the merits, the party shall be entitled to all cost and
expenses, including attorneys' fees, which it has incurred in enforcing its
rights under this Section 8.02.

                 (d)      As used herein, "Specified Expenses" means all
reasonable out-of-pocket expenses and fees actually incurred by a Person or on
its behalf in connection with the Transactions prior to the termination of this
Agreement (including without limitation, all reasonable fees and expenses of
counsel, financial advisors, banks or other entities providing financing to
such Person (including financing, commitment and other fees payable thereto),
accountants, environmental and other experts and consultants to such Person and
its affiliates, all SEC or HSR Act related filing fees, and all printing and
advertising expenses) and in connection with the negotiation, preparation,
execution, performance and termination of this Agreement, the structuring of
the Transactions, any agreements relating thereto and any filings to be made in
connection therewith. Specified Expenses shall not include compensation of
employees of Parent or Target.

         SECTION 8.03. Amendment. This Agreement may be amended by the parties
hereto by action taken by or on behalf of their respective Boards of Directors
at any time prior to the Effective Time; provided, however, that, after the
approval and adoption of this Agreement and the Transactions by the Target
Stockholders, no amendment may be made which would violate Delaware Law. This
Agreement may not be amended except by an instrument in writing signed by the
parties hereto.

         SECTION 8.04. Waiver. At any time prior to the Effective Time, any
party hereto may (a) extend the time for the performance of any obligation or
other act of any other party hereto, (b) waive any inaccuracy in the
representations and warranties contained herein or in any document delivered
pursuant hereto and (c) waive compliance with any agreement or condition
contained herein. Any such extension or waiver shall be valid only if set forth
in an instrument in writing signed by the party or parties to be bound thereby.

                                   ARTICLE IX

                           ESCROW AND INDEMNIFICATION

         SECTION 9.01. Survival of Representations and Warranties. All of
Target's representations, warranties, covenants and agreements contained in
this Agreement or in any instrument delivered pursuant to this Agreement
(including without limitation, the Target Disclosure Schedule) relating to the
Intellectual Property Assets of Target, including without limitation pursuant
to Sections 3.09, 3.12 and 3.20 shall survive the Merger and continue until
5:00 p.m., Dallas, Texas time, one year following the Closing Date, (the
"Expiration Date"). Except as provided in the immediately preceding sentence,
none of the Target's representations, warranties, covenants, and agreements
shall survive the Closing Date. None of Parent's representations, warranties,
covenants and agreements contained in this Agreement or in any instrument
delivered pursuant to this Agreement (including without limitation, the Parent
Disclosure Schedule) shall survive the Merger.

         SECTION 9.02. Parent Escrow Arrangements.

                 (a)      Parent Escrow Fund. At the Effective Time the Target
Stockholders (except Target Stockholders, in respect of Dissenting Shares) will
be deemed to have received and deposited with the Escrow Agent (as defined
below) that amount of the Merger Consideration that is equal to their
proportionate share of the Parent Escrow Amount (which shall not include that
portion of the Parent Escrow Amount which is allocated for contribution by
holders of Target Options assumed by Parent). As soon as practicable after the
Effective Time, the Parent Escrow Amount, without any act of any Target
Stockholder, will be deposited with an institution designated by Parent and
reasonably acceptable to the Representative (as defined in Section 9.02(g)
below)) as escrow agent (the "Escrow Agent"). The Parent Escrow Amount as
increased or reduced by any earnings or losses thereon, together with other
shares deposited in respect of Target Options assumed by Parent and exercised
between the Effective Time and the Expiration Date, plus a proportionate share
of any additional shares as may be issued in respect of such shares upon any
stock split, stock dividend or recapitalization effected by Parent after the
Effective Time and prior to the Expiration Date, shall constitute an escrow
fund (the "Parent Escrow Fund") and shall be governed by the terms set forth
herein and in an escrow agreement to be agreed upon by the parties and to be
entered into by and among, Parent, the Representative and the Escrow Agent (the
"Parent Escrow Agreement"). The portion of the Parent Escrow Amount contributed
on behalf of each Target Stockholder shall be in proportion to the aggregate
amount of the Merger Consideration which such holder would otherwise be
entitled to receive under Section 2.01, plus the number of Target Options
subject to adjustment under this Section 9.02 and Section 2.04(a)(iv). Upon the
exercise of any Target Option between the Effective Time and the Expiration
Date, five percent (5%) of the shares of Parent Common Stock issued upon such
exercise shall be added and deposited to the Parent Escrow Fund upon such
exercise, and at the expiration of the Escrow Period (as defined in Section
9.02(b)), any Target Options not so exercised as of the expiration of the





                                       46
<PAGE>   52
Escrow Period shall be adjusted in accordance with Section 2.04(a)(iv). The
Parent Escrow Fund shall be the sole and exclusive remedy available to
compensate Parent and its affiliates for any claims, losses, liabilities,
damages, deficiencies, costs and expenses, including reasonable attorneys' fees
and expenses, and expenses of investigation and defense (hereinafter
individually a "Loss" and collectively "Losses"), incurred by Parent, its
officers, directors, or affiliates (including the Surviving Corporation)
directly as a result of any inaccuracy or Breach of a representation, warranty,
covenant or agreement of Target contained in this Agreement (without regard to
any update or modification of the Target Disclosure Schedule following the date
of this Agreement), or any instrument delivered pursuant to this Agreement
relating to the Intellectual Property Assets of Target, including without
limitation pursuant to Sections 3.09, 3.12 and 3.20. Parent shall act in good
faith and in a commercially reasonable manner to mitigate all Losses it may
suffer. Parent may not receive any cash or shares from the Parent Escrow Fund
(and no adjustment shall be made pursuant to Section 2.04(a)(iv)) unless and
until Officer's Certificates (as defined in Section 9.02(d) below) identifying
Losses have been delivered to the Escrow Agent as provided in Section 9.02(e);
in such case, Parent may recover from the Parent Escrow Fund Losses to Parent
(and adjustment may be made pursuant to Section 2.04(a)(iv)).

                 (b)      Escrow Period; Distribution upon Termination of
Escrow Period. Subject to the following requirements, the Parent Escrow Fund
shall be in existence immediately following the Effective Time and shall
terminate at 5:00 p.m., Texas time, on the Expiration Date (the "Escrow
Period"). On the Expiration Date any remaining cash and shares comprising the
Parent Escrow Fund less any Loss shall be released from the Parent Escrow Fund
and distributed to the Target Stockholders and those individuals who have on or
prior to the Expiration Date exercised the Target Options assumed by Parent
(the "Escrow Release"). Notwithstanding the above, no Escrow Release shall
occur and the Escrow Period shall not terminate with respect to such amount (or
some portion thereof) that is necessary in the reasonable judgment of Parent,
subject to the objection of the Representative and the subsequent arbitration
of the matter in the manner provided in Section 9.02(f) hereof, to satisfy any
unsatisfied claims concerning facts and circumstances existing prior to the
contemplated date of the Escrow Release or the termination of the Escrow
Period, as the case may be, each as specified in an Officer's Certificate
delivered to the Escrow Agent prior to the contemplated date of an Escrow
Release or termination of the Escrow Period, as appropriate. As soon as all
such claims have been resolved, the Escrow Agent shall deliver to the Target
Stockholders the amount which is subject to an Escrow Release or at the end of
the Escrow Period, as appropriate the remaining portion of the Parent Escrow
Fund not required to satisfy such claims. Deliveries pursuant to this Section
9.02(b) of cash from the Parent Escrow Fund to the Target Stockholders and
shares of Parent Common Stock from the Parent Escrow Fund to those individuals
who have exercised Target Options between the Effective Time and the Expiration
Date shall be made in proportion to their respective original contributions to
the Parent Escrow Fund.

                 (c)      Protection of Parent Escrow Fund.

                          (i)     Any shares of Parent Common Stock or other
                 equity securities issued or distributed by Parent (including
                 shares issued upon a stock split) ("New Shares") in respect of
                 Parent Common Stock in the Parent Escrow Fund which have not
                 been released from the Parent Escrow Fund shall be added to
                 the Parent Escrow Fund and become a part thereof. New Shares
                 issued in respect of shares of Parent Common Stock which have
                 been released from the Parent Escrow Fund shall not be added
                 to the Parent Escrow Fund but shall be distributed to the
                 record holders thereof. Cash dividends on Parent Common Stock
                 shall not be added to the Parent Escrow Fund and not
                 distributed to the record holders thereof.

                          (ii)    Each Target Stockholder and each individual
                 who, prior to the Expiration Date, has exercised the Target
                 Options assumed by Parent shall have voting rights with
                 respect to the shares of Parent Common Stock contributed to
                 the Parent Escrow Fund by such party (and on any voting
                 securities added to the Parent Escrow Fund in respect of such
                 shares of Parent Common Stock).

                 (d)      Claims Upon Parent Escrow Fund.

                          (i)     Upon receipt by the Escrow Agent at any time
                 on or before the last day of the Escrow Period, as
                 appropriate, of a certificate signed by any officer of Parent
                 (an "Officer's Certificate"): (A) stating that Parent has paid
                 or properly accrued or reasonably anticipates that it will
                 have to pay or accrue Losses, and (B) specifying in reasonable
                 detail the individual items of Loss included in the amount so
                 stated, the date each such item was paid or properly accrued,
                 or the basis for such anticipated liability, and the nature of
                 the misrepresentation, Breach of warranty or covenant to which
                 such item is related, the Escrow Agent shall, subject to the
                 provisions of Section 9.02(e) hereof, deliver to Parent out of
                 the Parent Escrow Fund, as promptly as practicable, cash and
                 shares of Parent Common Stock held in the Parent Escrow Fund
                 in an amount equal to such Losses.

                          (ii)    For the purposes of determining the number of
                 shares of Parent Common Stock to be delivered to Parent out of
                 the Parent Escrow Fund pursuant to Section 9.02(d)(i) hereof,
                 the shares of Parent Common Stock and the adjustment to the
                 number of Target Options issuable under Section 2.04(a)(iv)
                 shall be valued at the average of the reported last sale price
                 of a share of Parent Common Stock as reported by Nasdaq for
                 the 10 consecutive trading days ending immediately preceding
                 the second trading day before the date such determination is
                 made. Parent and the Representative shall certify





                                       48
<PAGE>   54
                 such value in a certificate signed by both Parent and the
                 Representative, and shall deliver such certificate to the
                 Escrow Agent.

                          (iii)   Notwithstanding the foregoing, Parent shall
                 not be entitled to make a claim for payment of Losses under
                 this Section 9.02(d) until Parent has suffered Losses of
                 $100,000 in the aggregate and thereafter Parent shall be
                 entitled to indemnification for all Losses without regard to
                 such $100,000 threshold.

                 (e)      Objections to Claims. At the time of delivery of any
Officer's Certificate to the Escrow Agent, a duplicate copy of such certificate
shall be delivered by Parent to the Representative and for a period of thirty
(30) days after such delivery, the Escrow Agent shall make no delivery to
Parent of any cash or shares from the Parent Escrow Fund pursuant to Section
9.02(d) hereof unless the Escrow Agent shall have received written
authorization from the Representative to make such delivery. After the
expiration of such thirty (30) day period, the Escrow Agent shall make delivery
of cash and shares of Parent Common Stock from the Parent Escrow Fund in
accordance with Section 9.02(d) hereof, provided that no such payment or
delivery may be made if the Representative shall object in a written statement
(the "Representative Agent Notice") to the claim made in the Officer's
Certificate, and such statement shall have been delivered to the Escrow Agent,
with a copy to Parent, prior to the expiration of such thirty (30) day period.

                 (f)      Resolution of Conflicts; Arbitration.

                          (i)     In case the Representative shall so object in
                 writing to any claim or claims made in any Officer's
                 Certificate, the Representative and Parent shall attempt in
                 good faith to agree upon the rights of the respective parties
                 with respect to each of such claims. If the Representative and
                 Parent should so agree, a memorandum setting forth such
                 agreement shall be prepared and signed by both parties and
                 shall be furnished to the Escrow Agent. The Escrow Agent shall
                 be entitled to rely on any such memorandum and distribute cash
                 and shares of Parent Common Stock from the Parent Escrow Fund
                 in accordance with the terms thereof.

                          (ii)    If no such agreement is reached within thirty
                 (30) days following receipt by the Escrow Agent of the
                 Representative Agent Notice, either Parent or the
                 Representative may demand arbitration of the matter unless the
                 amount of the Loss is at issue in pending litigation with a
                 third party, in which event arbitration shall not be commenced
                 until such amount is ascertained or both parties agree to
                 arbitration; and in either such event the matter shall be
                 settled by arbitration conducted by three arbitrators. Parent
                 and the Representative shall each select one arbitrator, and
                 the two arbitrators so selected shall select a third
                 arbitrator, each of which arbitrators shall be





                                       49
<PAGE>   55
                 independent and have at least ten years relevant experience.
                 The arbitrators shall set a limited time period and establish
                 procedures designed to reduce the cost and time for discovery
                 while allowing the parties an opportunity, adequate in the
                 sole judgment of the arbitrators, to discover relevant
                 information from the opposing parties about the subject matter
                 of the dispute. The arbitrators shall rule upon motions to
                 compel or limit discovery and shall have the authority to
                 impose sanctions, including attorneys' fees and costs, to the
                 same extent as a court of competent law or equity, should the
                 arbitrators determine that discovery was sought without
                 substantial justification or that discovery was refused or
                 objected to without substantial justification. The decision of
                 a majority of the three arbitrators as to the validity and
                 amount of any claim in such Officer's Certificate shall be
                 binding and conclusive upon the parties to this Agreement, and
                 notwithstanding anything in Section 9.02(e) hereof, the Escrow
                 Agent shall be entitled to act in accordance with such
                 decision and make or withhold payments out of the Parent
                 Escrow Fund in accordance therewith. Such decision shall be
                 written and shall be supported by written findings of fact and
                 conclusions which shall set forth the award, judgment, decree
                 or order awarded by the arbitrators.

                          (iii)   Judgment upon any award rendered by the
                 arbitrators may be entered in any court having jurisdiction.
                 Any such arbitration shall be held in New York, New York under
                 the American Arbitration Association rules then in effect. The
                 non-prevailing party to an arbitration shall pay its own
                 expenses, the fees of each arbitrator, the administrative
                 costs of the arbitration, and the expenses, including without
                 limitation, reasonable attorneys' fees and costs, incurred by
                 the other party to the arbitration.

                 (g)      Representative of the Stockholders; Power of
Attorney.

                          (i)     At the Effective Time, and without further
                 act of any party, Robert P. Goodman shall be appointed as
                 agent and attorney-in-fact (the "Representative") for each
                 Target Stockholder (except such Target Stockholders, if any,
                 as shall have perfected their appraisal rights under Delaware
                 Law) and each holder of Target Options, for and on behalf of
                 Target Stockholders and the holders of the Target Options, to
                 give and receive notices and communications, to authorize
                 delivery to Parent of cash and shares of Parent Common Stock
                 from the Parent Escrow Fund in satisfaction of claims by
                 Parent, to object to such deliveries, to agree to, negotiate,
                 enter into settlements and compromises of, and demand
                 arbitration and comply with orders of courts and awards of
                 arbitrators with respect to such claims, and to take all
                 actions necessary or appropriate in the judgment of
                 Representative for the accomplishment of the foregoing. Such
                 agency may be changed by the Target Stockholders from time to
                 time upon not less than thirty (30) days prior





                                       50
<PAGE>   56
                 written notice to Parent; provided that the Representative may
                 not be removed unless holders of at least a majority in
                 interest of the Parent Escrow Fund agree to such removal and
                 to the identity of the substituted agent. Any vacancy in the
                 position of Representative may be filled by approval of the
                 holders of a majority in interest of the Parent Escrow Fund.
                 No bond shall be required of the Representative, and the
                 Representative shall not receive compensation for his or her
                 services. Notices or communications to or from the
                 Representative relating to the Parent Escrow Fund shall
                 constitute notice to or from each of the Target Stockholders.

                          (ii)    The Representative shall not be liable for
                 any act done or omitted hereunder as Representative while
                 acting in good faith. The Target Stockholders on whose behalf
                 the Parent Escrow Amount was contributed to the Parent Escrow
                 Fund shall severally indemnify the Representative and hold the
                 Representative harmless against any loss, liability or expense
                 incurred without negligence or bad faith on the part of the
                 Representative and arising out of or in connection with the
                 acceptance or administration of the Representative's duties
                 hereunder, including the reasonable fees and expenses of any
                 legal counsel retained by the Representative.

                 (h)      Actions of the Representative. A decision, act,
consent or instruction of the Representative relating to the Parent Escrow Fund
shall constitute a decision of all Target Stockholders (except such Target
Stockholders if any, as shall have perfected appraisal rights under Delaware
Law) and all holders of Target Options assumed by Parent, and shall be final,
binding and conclusive upon each of such Target Stockholders, and the Escrow
Agent and Parent may rely upon any such decision, act, consent or instruction
of the Representative as being the decision, act, consent or instruction of
each such Target Stockholder and each such holder of Target Options. In the
absence of bad faith, the Escrow Agent and Parent are hereby relieved from any
liability to any person for any acts done by them in accordance with such
decision, act, consent or instruction of the Representative.

                 (i)      Third-Party Claims. In the event Parent becomes aware
of a third-party claim which Parent believes may result in a demand against the
Parent Escrow Fund, Parent shall notify the Representative of such claim, and
the Representative, as representative for the Target Stockholders and the
holders of the Target Options, shall be entitled, at their expense, to
participate in any defense of such claim. Parent shall have the right in its
sole discretion to settle any such claim; provided, however, that except with
the consent of the Representative, no settlement of any such claim with
third-party claimants shall alone be determinative of the amount of any claim
against the Parent Escrow Fund. In the event that the Representative has
consented to any such settlement and acknowledged that the claim is a valid
claim against the Parent Escrow Fund, the Representative shall have no power or
authority to object under any provision of this Article IX to the amount of any
claim by Parent against the Parent Escrow Fund with respect to such settlement.

         SECTION 9.03. Representative Escrow Arrangements.

                 (a)      Representative Escrow Fund. At the Effective Time the
Target Stockholders (except Target Stockholders, in respect of Dissenting
Shares) will be deemed to have received and deposited with the Escrow Agent
that amount of the Merger Consideration that is equal to their proportionate
share of the Representative Escrow Amount. As soon as practicable after the
Effective Time, the Representative Escrow Amount, without any act of any Target
Stockholder, will be deposited with the Escrow Agent. The Representative Escrow
Amount as increased or reduced by any earnings or losses thereon, together with
other shares deposited in respect of Target Options assumed by Parent and
exercised between the Effective Time and the Expiration Date, plus a
proportionate share of any additional shares as may be issued in respect of
such shares upon any stock split, stock dividend or recapitalization effected
by Parent after the Effective Time and prior to the Expiration Date, shall
constitute an escrow fund (the "Representative Escrow Fund") and shall be
governed by the terms set forth herein and in an escrow agreement to be agreed
upon by the parties and to be entered into by and between the Representative
and the Escrow Agent (the "Representative Escrow Agreement"). The portion of
the Representative Escrow Amount contributed on behalf of each Target
Stockholder shall be in proportion to the aggregate amount of the Merger
Consideration which such holder would otherwise be entitled to receive under
Section 2.01, plus the number of Target Options subject to adjustment under
this Section 9.03 and Section 2.04(a)(iv). Upon the exercise of any Target
Option between the Effective Time and the Expiration Date, three hundred and
thirty-three one-thousandths percent (.333%) of the shares of Parent Common
Stock issued upon such exercise shall be added and deposited to the
Representative Escrow Fund upon such exercise, and at the expiration of the
Escrow Period, any Target Options not so exercised as of the expiration of the
Escrow Period shall be adjusted in accordance with Section 2.04(a)(iv). The
Representative Escrow Fund shall be used to pay for the costs and expenses,
including reasonable attorneys' fees and expenses, and expenses of
investigation and defense (hereinafter individually a "Representative Expense"
and collectively "Representative Expenses"), incurred by Representative in
performing his or her obligations under this Article IX.

                 (b)      Representative Escrow Period; Distribution Upon
Termination of Representative Escrow Period.  Subject to the following
requirements, the Representative Escrow Fund shall be in existence immediately
following the Effective Time and shall terminate at 5:00 p.m., Texas time, on
the Expiration Date (the "Representative Escrow Period"). On the Expiration
Date any remaining cash and shares comprising the Representative Escrow Fund
less any additional Representative Expenses shall be released from the
Representative Escrow Fund and distributed to the Target Stockholders (the
"Representative Escrow Release"). Notwithstanding the above, no Representative
Escrow Release shall occur and the Representative Escrow Period shall not
terminate with respect to such amount (or some portion thereof) that is
necessary in the reasonable judgment of Representative to satisfy any
unsatisfied claims concerning facts and circumstances existing





                                       52
<PAGE>   58
prior to the contemplated termination of the Representative Escrow Period. As
soon as all such claims have been resolved, the Escrow Agent shall deliver to
the Target Stockholders the amount which is subject to a Representative Escrow
Release and the remaining portion of the Representative Escrow Fund not
required to satisfy such claims.  Deliveries pursuant to this Section 9.03(b)
of cash from the Representative Escrow Fund to the Target Stockholders and
shares of Parent Common Stock from the Parent Escrow Fund to those individuals
who have exercised Target Options between the Effective Time and the Expiration
Date shall be made in proportion to their respective original contributions to
the Representative Escrow Fund.

                 (c)      Protection of Representative Escrow Fund.

                          (i)     Any shares of Parent Common Stock or other
                 equity securities issued or distributed by Parent (including
                 shares issued upon a stock split) ("New Shares") in respect of
                 Parent Common Stock in the Representative Escrow Fund which
                 have not been released from the Representative Escrow Fund
                 shall be added to the Representative Escrow Fund and become a
                 part thereof. New Shares issued in respect of shares of Parent
                 Common Stock which have been released from the Representative
                 Escrow Fund shall not be added to the Representative Escrow
                 Fund but shall be distributed to the record holders thereof.
                 Cash dividends on Parent Common Stock shall not be added to
                 the Representative Escrow Fund and not distributed to the
                 record holders thereof.

                          (ii)    Each Target Stockholder shall have voting
                 rights with respect to the shares of Parent Common Stock
                 contributed to the Representative Escrow Fund by such party
                 (and on any voting securities added to the Representative
                 Escrow Fund in respect of such shares of Parent Common Stock).

                 (d)      Claims Upon Representative Escrow Fund.

                          (i)     Upon receipt by the Escrow Agent at any time
                 on or before the last day of the Representative Escrow Period,
                 as appropriate, of a certificate signed by the Representative
                 stating that Representative has paid or properly accrued or
                 reasonably anticipates that it will have to pay or accrue
                 Representative Expenses, the Escrow Agent shall deliver to
                 Representative out of the Representative Escrow Fund, as
                 promptly as practicable, cash and shares of Parent Common
                 Stock held in the Representative Escrow Fund in an amount
                 equal to such Representative Expenses.

                          (ii)    For the purposes of determining the number of
                 shares of Parent Common Stock to be delivered to
                 Representative out of the Representative Escrow Fund pursuant
                 to Section 9.03(d)(i) hereof, the shares of Parent

                               CONSENT AGREEMENT

         This Consent Agreement ("Agreement") is made and entered into as of
________ ___, 1997 by and between DSC Communications Corporation, a Delaware
corporation ("Parent"), and the undersigned director, executive officer, or
affiliate of Celcore, Inc., a Delaware corporation ("Target").

                                    RECITALS

         A.      Parent, Target and CI Acquisition Company, a Delaware
corporation and a wholly-owned subsidiary of Parent ("Parent Sub"), contemplate
entering into an Amended and Restated Agreement and Plan of Merger (the "Merger
Agreement"), providing for the merger of Parent Sub with and into Target (the
"Merger"), pursuant to which Target will become a wholly-owned subsidiary of
Parent.

         B.      Capitalized terms used herein and not defined have the meaning
for them set forth in the Merger Agreement.

         C.      The stockholder named on the signature page hereof (the
"Stockholder") is the beneficial holder of record of the number and class of
shares of the outstanding Target Stock, as is indicated on the final page of
this Agreement (the "Shares"). In connection with the Merger, Parent will
acquire the Stockholder's entire equity interest in Target and the Stockholder
will receive in exchange the Merger Consideration in accordance with the terms
of the Merger Agreement. In consideration of and in order to induce the
execution of the Merger Agreement by Parent, the Stockholder agrees not to sell
or otherwise dispose of any shares of Target Stock held by the Stockholder and
to vote the Shares so as to facilitate consummation of the Merger as more fully
described below.

         NOW, THEREFORE, in consideration of the mutual promises and the mutual
covenants and agreements contained herein, the parties agree as follows:

         1.      Agreement to Retain Shares. The Stockholder agrees not to
transfer, pledge, sell, exchange or offer to transfer or sell or otherwise
dispose of or encumber any of the Shares or to make any offer or agreement
relative thereto at any time prior to the Expiration Date. The "Expiration
Date" shall mean the earlier of (a) the date and time on which the Merger shall
become effective in accordance with the terms and provisions of the Merger
Agreement, or (b) the date on which the Merger Agreement shall be terminated
pursuant to the Merger Agreement.

         2.      Agreement to Vote Shares; Waiver of Liquidation Rights and
Appraisal Rights. At any meeting of the Target Stockholders called with respect
to any of the following, and at





                                      B-1
<PAGE>   73
any adjournment thereof, and on every action by written consent of the Target
Stockholders with respect to any of the following, the Stockholder shall vote
the Shares in favor of approval of (i) the Merger Agreement and the Merger and
any matter that could reasonably be expected to facilitate the Merger, (ii) the
payments under the employment agreements for Messrs. Berger, Foley, and
Gonzalez which are being entered into with such individuals in connection with
the Merger, (iii) the waiver of any rights to receive cash or other property
upon a liquidation of Target as provided in the certificate of incorporation of
Target or in any of the Certificates of Designations in respect of any Target
Preferred Stock and (iv) the amendments to the Target's certificate of
incorporation (including its Certificates of Designations), as contemplated by
Annex B to this Agreement. The Stockholder, as the holder of voting stock of
Target shall be present in person or by proxy, at all meetings of Target
Stockholders so that all Shares are counted for the purposes of determining the
presence of a quorum at such meetings. This Agreement is intended to bind the
Stockholder only with respect to the specific matters set forth herein, and
shall not prohibit the Stockholder from action in accordance with his fiduciary
duties as an officer or director of Target. In respect of the Merger, the
Stockholder hereby waives (x) any rights to receive cash or other property upon
a liquidation of Target as provided in the certificate of incorporation of
Target or any of the Certificates of Designations in respect of any Target
Preferred Stock owned by such Stockholder and (y) any right to receive the
notice under Article Fourth, Section E(iv)(e) of the Target's Certificate of
Incorporation and Section D(iv)(e) of each of the Target's Certificates of
Designations. In addition, the Stockholder agrees not to take any action or
actions to perfect any appraisal rights the Stockholder may have as a result of
the Merger under Section 262 of the Delaware Law and hereby waives all rights
to appraisal under Section 262 of the Delaware Law.

         3.      Irrevocable Proxy. By execution of this Agreement, the
Stockholder hereby irrevocably appoints and constitutes Robert P. Goodman (the
"Proxyholder"), the agent and proxy of the Stockholder, with full power of
substitution and resubstitution, to the full extent of the Stockholder's rights
with respect to the shares of capital stock of Target beneficially owned by the
Stockholder, which shares are listed below (the "Shares"), and any and all
other shares or securities issued or issuable in respect thereof on or after
the date hereof and prior to the date this proxy terminates, to vote the
Shares, or to execute written consents in lieu of a stockholders meeting, in
favor of approval of the (i) Merger and the Merger Agreement, and any matter
that could reasonably be expected to facilitate the Merger, (ii) the payments
under the employment agreements for Messrs. Berger, Foley, and Gonzalez which
are being entered into with such individuals in connection with the Merger,
(iii) the waiver of the right of the Stockholder to receive cash or other
property upon a liquidation of Target as provided in the certificate of
incorporation of Target or in any of the Certificates of Designations in
respect of any Target Preferred Stock and (iv) the amendments to the Target's
certificate of incorporation (including its Certificates of Designations), as
set forth on Annex B to this Agreement. The Proxyholder may not exercise the
proxy contained in this Section 3 on any other matter. The Stockholder may vote
the Shares on all such other matters. The proxy granted by the Stockholder to

secure the obligations of the Stockholders set forth in Section 2 hereof,





                                      B-2
<PAGE>   74
and is irrevocable and coupled with an interest in such obligations and in the
interests in Target to be purchased and sold pursuant the Merger Agreement. The
proxy contained in this Section 3 will terminate upon the termination of this
Agreement in accordance with its terms. Upon the execution hereof, other than
any irrevocable proxy previously given by the Stockholder to the Proxyholder in
connection with that certain Voting Agreement dated on or about October 29,
1997 by and between Stockholder and Parent, all prior proxies given by the
Stockholder with respect to the Shares and any and all other shares or
securities issued or issuable in respect thereof on or after the date hereof,
are hereby revoked and no subsequent proxies will be given until such time as
this proxy shall be terminated in accordance with its terms. The Stockholder
authorizes the Proxyholder to file this proxy and any substitution with the
Secretary of Target and with any Inspector of Elections at any meeting of the
Target Stockholders. The proxy contained in this Section 3 is irrevocable and
shall survive the insolvency, incapacity, death or liquidation of the
Stockholder. Stockholder acknowledges and agrees that a copy, facsimile
telecommunication or other reproduction of this Agreement may be substituted or
used in lieu of the original writing or transmission for any and all purposes
for which the an original of this Agreement could be used.

         4.      Additional Purchases. For purposes of this Agreement
(including without limitation, the recitals hereto), the term "Shares" shall
include any shares of Target capital stock (including Target Stock) that the
Stockholder purchases or as to which the Stockholder otherwise acquires voting
power after the execution of this Agreement and prior to the Expiration Date.

         5.      Representations, Warranties and Covenants of the Stockholder.
The Stockholder hereby represents, warrants and covenants to Parent the
following:

                 (a)      Ownership of Shares. Except as specifically described
on Annex A to this Agreement (if any), the Stockholder (i) is the holder and
beneficial owner of the Shares, which at the date hereof and at all times until
the Expiration Date will be free and clear of any liens, claims, options,
charges or other encumbrances, (ii) does not beneficially own any shares of
Target Stock other than the Shares and (iii) has full power and authority to
make, enter into, deliver and carry out the terms of this Agreement and the
Proxy.

                 (b)      No Voting Trusts and Agreements. The Stockholder will
not, and will not permit any entity under the Stockholder's control to, deposit
any shares of Target capital stock (including Target Stock) held by the
Stockholder or such entity in a voting trust or subject any shares of Target
capital stock (including Target Stock) held by the Stockholder or such entity
to any arrangement or agreement with respect to the voting of such shares of
capital stock, other than agreements entered into with Parent or its
affiliates.

                 (c)      No Proxy Solicitations. The Stockholder will not, and
will not permit any entity under the Stockholder's control to, (i) solicit
proxies or become a participant in a "solicitation" (as such term is defined in
Rule 14a-11 under the Securities Exchange Act of





                                      B-3
<PAGE>   75
1934, as amended (the "Exchange Act")), with respect to any proposal made in
opposition to or competition with consummation of the Merger and the Merger
Agreement, any merger, consolidation, share exchange, sale of securities or
assets, reorganization, recapitalization or other business combination
involving Target and any other party (other than Parent and its affiliates),
any liquidation (including pursuant to the liquidation rights provided for in
the Certificates of Designations), or winding up of Target and any other matter
that would, or could reasonably be expected to, prohibit or discourage the
Merger (each of the foregoing is referred to as an "Opposing Proposal"), or
otherwise encourage or assist any party in taking or planning any action that
would compete with, restrain or otherwise serve to interfere with or inhibit
the timely consummation of the Merger in accordance with the terms of the
Merger Agreement, (ii) initiate a Stockholders' vote or action by consent of
Target Stockholders with respect to an Opposing Proposal or (iii) become a
member of a "group" (as such term is used in Section 13(d) of the Exchange Act)
with respect to any voting securities of Target with respect to an Opposing
Proposal.

         6.      Representations, Warranties and Covenants of Parent. Parent
represents, warrants and covenants to the Stockholder as follows:

                 (a)      Due Authorization. This Agreement has been authorized
by all necessary corporate action on the part of Parent and has been duly
executed by a duly authorized officer of Parent.

                 (b)      Validity; No Conflict. This Agreement constitutes the
legal, valid and binding obligation of Parent. Neither the execution of this
Agreement by Parent nor the consummation of the transactions contemplated
hereby will result in a breach or violation of the terms of any agreement by
which Parent is bound or of any decree, judgment, order, law or regulation now
in effect of any court or other governmental body applicable to Parent.

         7.      Additional Documents. The Stockholder and Parent hereby
covenant and agree to execute and deliver any additional documents necessary or
desirable, in the reasonable opinion of Parent's legal counsel or the
Stockholder, as the case may be, to carry out the intent of this Agreement.

         8.      Consent and Waiver. The Stockholder hereby gives any consent
or waivers that are reasonably required for the consummation of the Merger
under the terms of any agreement to which the Stockholder is a party or
pursuant to any rights the Stockholder may have.

         9.      Miscellaneous.

                 (a)      Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction to
be invalid, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions of this Agreement shall remain in full force and
effect and shall in no way be affected, impaired or invalidated.

                 (b)      Binding Effect and Assignment. This Agreement and all
of the provisions hereof shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and permitted assigns, but,
except as otherwise specifically provided herein, neither this Agreement nor
any of the rights, interests or obligations of the parties hereto may be
assigned by any of the parties without the prior written consent of the other.

                 (c)      Amendments and Modifications. 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.

                 (d)      Specific Performance; Injunctive Relief. The parties
hereto acknowledge that Parent will be irreparably harmed and that there will
be no adequate remedy at law for a violation of any of the covenants or
agreements of the Stockholder set forth herein. Therefore, it is agreed that,
in addition to any other remedies that may be available to Parent upon such
violation, Parent shall have the right to enforce such covenants and agreements
by specific performance, injunctive relief or by any other means available to
it at law or in equity.

                 (e)      Notices. All notices, requests, claims, demands and
other communications hereunder shall be in writing and sufficient if delivered

or to such other address as either party may have furnished to the other in
writing in accordance herewith, except that notices of change of address shall
only be effective upon receipt.

                 (f)      Governing Law. This Agreement shall be governed by,
construed and enforced in accordance with the laws of the State of Delaware
without giving effect to principles of conflicts of law.

                 (g)      Entire Agreement. This Agreement, together with that
certain Voting Agreement dated on or about October 29, 1997 by and between the
Stockholder and Parent, contain the entire understanding of the parties in
respect of the subject matter hereof, and supersedes all prior negotiations and
understanding between the parties with respect to such subject matter.

                 (h)      Counterparts. This Agreement may be executed in
counterparts, each of which shall be an original, but all of which together
shall constitute one and the same agreement.

                 (i)      Effect of Headings. The section headings herein are
for convenience only and shall not affect the construction or interpretation of
this Agreement.

                 (j)      Termination. Notwithstanding anything else in this
Agreement, this Agreement and the Proxy, and all obligations of the Stockholder
under either of them, shall automatically terminate as of the Expiration Date.

                 (k)      Covenant Not-to-Compete. [ROBERT GOODMAN ONLY]

                 (i)      Stockholder acknowledges that Parent is acquiring the
         goodwill of Target. Therefore, Stockholder agrees that for a period
         commencing upon the Closing Date and ending upon the fifth anniversary
         thereof, unless otherwise extended pursuant to the terms hereof,
         Stockholder will not, directly or indirectly, either as an employer,





                                      B-6
<PAGE>   78
         consultant, agent, principal, partner, stockholder, or in any other
         capacity, engage or participate in any business that is involved in
         the development, marketing, manufacturing or sale of GSM or AMPS
         mobile switching centers (a "Prohibited Business"), within any state
         or country in which Target or Parent or its Subsidiaries is conducting
         or reasonably expects to conduct or expand its business (the "Covenant
         Not-to-Compete"). Stockholder represents to Parent that the
         enforcement of the restriction contained in this Section 9(k) would
         not be unduly burdensome to Stockholder and that in order to induce
         Parent to enter into this Agreement, Stockholder further represents
         and acknowledges that Stockholder is willing and able to compete in
         other geographical areas not prohibited by this Section 9(k).
         Notwithstanding the foregoing, Stockholder shall not be prohibited
         from owning up to five percent (5%) of the outstanding capital stock
         of any class of capital stock registered under Section 12 (b) or (g)
         of the Exchange Act.

                 (ii)     Stockholder agrees that a breach or violation of the
         Covenant Not-to-Compete by Stockholder shall entitle Parent, as a
         matter of right, to an injunction issued by any court or arbitration
         panel of competent jurisdiction, restraining any further or continued
         breach or violation of this covenant. Such right to an injunction
         shall be cumulative and in addition to, and not in lieu of, any other
         remedies to which Parent may show itself justly entitled. Further,
         during any period in which Stockholder is in breach of the Covenant
         Not-to-Compete, the time period of the Covenant Not-to-Compete shall
         be extended for an amount of time that Stockholder is in breach
         hereof.

                 (iii)    In addition to the restrictions set forth in
         sub-paragraph (i) of this Section 9(k), Stockholder shall not for a
         period commencing upon the Closing Date and ending upon the first
         anniversary thereof, either directly or indirectly, (A) make known to
         any person, firm or corporation involved in a Prohibited Business the
         names and addresses of any of the customers of Target or contacts of
         Target or any other information pertaining to such persons, (B) call
         on, solicit, or take away, or attempt to call on, solicit or take away
         any of the customers of Target on whom Stockholder called or with whom
         Stockholder became acquainted during Stockholder's association with
         Target, for any other person, firm or corporation involved in a
         Prohibited Business or (C) recruit or hire or attempt to recruit or
         hire, directly or by assisting others, any employee, consultant or
         independent contractor of Target.

                 (iv)     The representations and covenants contained in this
         Section 9 on the part of Stockholder will be construed as ancillary to
         and independent of any other provision of this Agreement, and the
         existence of any proceeding of Stockholder against Target or any
         officer, director, or shareholder of Parent whether predicated on this
         Agreement or otherwise, shall not constitute a defense to the
         enforcement by Parent of the covenants of the Stockholder contained in
         this Section 9.





                                      B-7
<PAGE>   79
                 (v)      If Stockholder violates any covenant contained in
         this Section 9 and Parent brings legal action for injunctive or other
         relief, Parent shall not, as a result of the time involved in
         obtaining the relief, be deprived of the benefit of the full period of
         any such covenant. Accordingly, the covenants of Stockholder contained
         in this Section 9 shall be deemed to have durations as specified
         above, which periods shall commence upon the Closing Date and shall be
         extended for the amount of time between the Closing Date and the date
         of entry by a court of competent jurisdiction of a final judgment
         enforcing the covenants of Stockholder in this Section 9.

                 (vi)     The parties to this Agreement agree that the
         limitations contained in this Section 9 with respect to geographic
         area, duration and scope of activity are reasonable. However, if any
         court shall determine that the geographic area, duration or scope of
         activity of any restriction contained in this Section 9 is
         unenforceable, it is the intention of the parties that such
         restrictive covenant set forth herein shall not thereby be terminated
         but shall be deemed amended to the extent required to render it valid
         and enforceable.

         IN WITNESS WHEREOF, the parties have caused this Agreement to be duly
executed on the day and year first above written.

                          [TARGET COUNSEL LETTERHEAD]


                               December __, 1997



DSC Communications Corporation
1000 Coit Road
Plano, Texas 75075

Gentlemen:

We have acted as counsel to Celcore, Inc., a Delaware corporation (the
"Target"), in connection with the execution and delivery of the Amended and
Restated Agreement and Plan of Merger (the "Agreement"), dated as of December
__, 1997, among DSC Communications Corporation, a Delaware corporation
("Parent"), CI Acquisition Company, a Delaware corporation and a direct,
wholly-owned subsidiary of Parent ("Parent Sub"), and Target providing for the
merger of Parent Sub with and into Target (the "Merger"). This opinion letter
is being furnished to you pursuant to Section 7.02 of the Agreement.  Unless
otherwise defined herein or the context hereof otherwise requires, each term
used herein with its initial letter capitalized has the meaning given to such
term in the Agreement.

We have examined and are familiar with originals or copies, certified or
otherwise authenticated to our satisfaction, of such documents and records of
Target and each Target Subsidiary, and such statutes, regulations and
instruments as we have deemed necessary or advisable for the purposes of this
opinion letter, including, without limitation, (i) the Agreement, (ii) the
Certificate of Merger dated as of December __, 1997 between Target and Parent
Sub and (iii) the certificate of incorporation and bylaws of Target.

As to certain facts material to our opinions herein, we have assumed the
accuracy of the representations of Target in the Agreement and of one or more
officers of Target. In addition, we have assumed that all signatures on all
documents presented to us are genuine, that all documents submitted to us as
originals are accurate and complete, that all documents submitted to us as
copies are true and complete copies of the originals thereof, that all
information submitted to us was accurate and complete, and that all persons
executing and delivering originals or copies of documents examined by us were
competent to execute and deliver such documents. We have also assumed the due
authorization, execution and delivery





                                      C-1
<PAGE>   81
by the Parent and Parent Sub of the Agreement and the Certificate of Merger and
that the Agreement and the Certificate of Merger constitute legal, valid and
binding obligations of the Parent and Parent Sub enforceable against each of
them in accordance with their terms.

Based upon the foregoing and subject to the qualifications and limitations set
forth below, we are of the opinion that:

         1.      Target is duly incorporated, validly existing and in good
standing under the Laws of the jurisdiction of its incorporation and has the
requisite corporate power and authority to own, lease and operate its
properties and to carry on its business as it is now being conducted. Target is
duly qualified or licensed as a foreign corporation to do business, and is in
good standing in each jurisdiction where the character of the properties owned,
leased or operated by it or the nature of its business makes such qualification
or licensing necessary, except where the failure to be qualified or licensed
would not have a Material Adverse Effect.

         2.      Target has all necessary corporate power and authority to
execute and deliver the Agreement and to perform its obligations thereunder and
to consummate the Merger and the Transactions. The execution and delivery of
the Agreement by Target and the consummation by Target of the Transactions have
been duly and validly authorized by all necessary corporate action and no other
corporate proceedings on the part of Target are necessary to authorize the
Agreement or to consummate the Merger and the Transactions (other than the
recordation of an appropriate Certificate of Merger with the Secretary as
required by Delaware Law).

         3.      The Agreement has been duly and validly executed and delivered
by Target and constitutes a legal, valid and binding obligation of Target,
enforceable against Target in accordance with its terms, except as may be (i)
limited by bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium, or other Laws affecting enforcement of creditors' rights generally,
and (ii) subject to general principles of equity, regardless of whether
enforcement is considered in a Proceeding at law or in equity.

         4.      The execution and delivery of the Agreement by Target do not,
and the performance of the Agreement by Target and the consummation of the
Merger and the Transactions will not, (i) conflict with or violate the
certificate of incorporation or bylaws of Target, (ii) conflict with or violate
Delaware Law or the laws of the United States of America, or (iii) to the best
of our knowledge, result in any breach of or constitute a default (or an event
which with notice or lapse of time or both would become a default) under, or
give to others any right of termination, amendment, acceleration or
cancellation of, or result in the creation of a lien or other encumbrance on
any property or asset of Target or the Target Subsidiaries or require the
Consent of any third party pursuant to, any note, bond, mortgage, indenture,
Contract, license, permit, franchise or other instrument or obligation to which
Target or the Target Subsidiaries is a party or by which Target or the Target
Subsidiaries or any property or asset of Target or the Target Subsidiaries is
bound or affected.





                                      C-2
<PAGE>   82
         5.      The execution and delivery of the Agreement by Target do not,
and the performance of the Agreement and the Merger and the Transactions
contemplated thereby by Target will not, require any Consent or permit of, or
filing with or notification to, any federal or Delaware Governmental Authority,
except the filing and recordation of an appropriate Certificate of Merger with
the Secretary as required by Delaware Law.

         6.      Upon the issuance of a Certificate of Merger by the Secretary,
the Merger will become effective in accordance with the Agreement and the
Delaware Law, and each issued and outstanding share of Target Stock (other than
Dissenting Shares) will be converted into the consideration provided in Section
2.01 of the Agreement.

         7.      To the best of our knowledge, except as set forth in the
Target Disclosure Schedule, no Proceedings are pending or Threatened against
Target or the Target Subsidiaries seeking to prevent or delay the Merger or the
Transactions contemplated by the Agreement or challenging any of the terms or
provisions of the Agreement or seeking material damages in connection
therewith.

         8.      Immediately prior to the Merger, the authorized capital stock
of Target and each of the Target Subsidiaries is as set forth in Section 3.03
of the Agreement. Each share of Target Preferred Stock is convertible into one
share of Target Common Stock. All of the issued and outstanding shares of
capital stock of the Target Subsidiaries are held by Target and are validly
issued, fully paid and nonassessable and, to the best of our knowledge, not
subject to preemptive rights, except as identified in this Opinion. To the best
of our knowledge, no shares of capital stock of the Target have been acquired
by the Target that are subject to outstanding pledges by the Target to secure
the future payment of some or all of the purchase price for such shares. To the
best of our knowledge, other than the Target Options, as of the date of this
Agreement, there are no options, warrants or other rights, agreements,
arrangements or commitments of any character relating to the issued or unissued
capital stock of the Target obligating the Target to issue or sell any shares
of capital stock of, or other equity interests in, the Target or the Target
Subsidiaries. To the best of our knowledge, other than as set forth in Target's
certificate of incorporation (including the Target Certificate of
Designations), there are no outstanding contractual obligations of the Target
to repurchase, redeem or otherwise acquire any shares of Target Stock.

         9.      The Board of Directors of Target has approved the terms of the
Agreement and the Merger and the other Transactions, and such approval is
sufficient to render inapplicable to the Merger and the other Transactions the
provisions of Section 203 of the Delaware Law.

The preceding opinions and "negative assurance" statements are subject to the
following qualifications and limitations:

         A.      In connection with statements herein qualified by "to our
knowledge" or as to matters that have "come to our attention," our examination
has been limited to discussions





                                      C-3
<PAGE>   83
with the officers and other representatives of Target and each Target
Subsidiary by, and those statements refer only to what is in the actual
knowledge of, attorneys of this Firm who have been involved in the
representation of Target and the Target Subsidiaries in connection with the
Merger and the Transactions described in the Agreement, and we have made no
independent investigations as to the accuracy or completeness of any of the
representations, warranties, data or other information, written or oral, made
or furnished by Parent or Parent Sub to us or to you.

         B.       The opinions and statements expressed herein are limited to
the matters specifically addressed, and no opinion or statement is implied or
may be inferred beyond the matters so specifically addressed.

         C.      With respect to the opinion expressed in Paragraph 7, we have
not conducted any search of any indexes, dockets or other records of any court
or other Governmental Authority.

         D.      The opinions and statements expressed herein are rendered as
of the time immediately preceding the Effective Time, and we hereby disclaim
any obligation to advise you of, or to supplement any of our opinions or
statements because of, any changes in fact or Law which might affect any of
those opinions or statements.

         E.      We are licensed to practice law only in the State of Georgia
and are therefore unable to render an opinion regarding the laws of any
jurisdiction other than the State of Georgia. Accordingly, for purposes of this
opinion we have assumed that the laws of the State of Georgia and Delaware or
any other jurisdiction that is the subject of this opinion are the same.
Notwithstanding the foregoing, we are able to render an opinion with respect to
any matter covered by this opinion that is governed or controlled by Delaware
Law and accordingly our opinion is not subject to the foregoing limitation to
the extent it relates to Delaware Law.

         F.      This opinion letter is solely for your benefit in connection
with the Merger and the Transactions described in the Agreement and may not be
relied upon, quoted or otherwise used by any other person or entity or for any
other purpose without our express written consent.


                                        Very truly yours,

                                        POWELL, GOLDSTEIN, FRAZER

complete, that all documents submitted to us as copies are true and complete
copies of the originals thereof, that all information submitted to us was
accurate and complete, and that all persons executing and delivering originals
or copies of documents examined by us were competent to execute and deliver
such documents. We have also assumed the due authorization, execution and
delivery by Target of the Agreement and the Certificate of Merger and that the
Agreement and the Certificate of Merger constitute legal, valid and binding
obligations of Target enforceable against Target in accordance with their
terms.

Based upon the foregoing and subject to the qualifications and limitations set
forth below, we are of the opinion that:

         1.      Each of Parent and Parent Sub is duly incorporated, validly
existing and in good standing under the Laws of the jurisdiction of its
incorporation and has the requisite corporate power and authority to own, lease
and operate its properties and to carry on its business as it is now being
conducted. Each of Parent and Parent Sub is duly qualified or licensed as a
foreign corporation to do business, and is in good standing in each
jurisdiction where the character of the properties owned, leased or operated by
it or the nature of its business makes such qualification or licensing
necessary, except where the failure to be qualified or licensed would not have
a Material Adverse Effect.

         2.      Each of Parent and Parent Sub has all necessary corporate
power and authority to execute and deliver the Agreement and to perform its
obligations thereunder and to consummate the Merger and the Transactions. The
execution and delivery of the Agreement by Parent and Parent Sub and the
consummation by Parent and Parent Sub of the Transactions have been duly and
validly authorized by all necessary corporate action and no other corporate
proceedings on the part of Parent or Parent Sub are necessary to authorize the
Agreement or to consummate the Merger and the Transactions (other than the
recordation of an appropriate Certificate of Merger with the Secretary as
required by Delaware Law).

         3.      The Agreement has been duly and validly executed and delivered
by Parent and Parent Sub and constitutes a legal, valid and binding obligation
of each of Parent and Parent Sub, enforceable against each of Parent and Parent
Sub in accordance with its terms, except as may be (i) limited by bankruptcy,
insolvency, fraudulent conveyance, reorganization, moratorium, or other Laws
affecting enforcement of creditors' rights generally, and (ii) subject to
general principles of equity, regardless of whether enforcement is considered
in a Proceeding at law or in equity.

          4.     The execution and delivery of the Agreement by Parent and
Parent Sub do not, and the performance of the Agreement by Parent and Parent
Sub and the consummation of the Merger and the Transactions will not, (i)
conflict with or violate the certificate of incorporation or bylaws of either
Parent or Parent Sub, (ii) conflict with or violate Delaware Law or the laws of
the United States of America, or (iii) to the best of our knowledge, result in
any breach of or constitute a default (or an event which with notice or lapse
of time or both would become





                                      D-2
<PAGE>   86
a default) under, or give to others any right of termination, amendment,
acceleration or cancellation of, or result in the creation of a lien or other
encumbrance on any property or asset of Parent or Parent Sub or require the
Consent of any third party pursuant to, any note, bond, mortgage, indenture,
Contract, license, permit, franchise or other instrument or obligation to which
Parent or Parent Sub is a party or by which Parent or Parent Sub or any
property or asset of Parent or Parent Sub is bound or affected.

         5.      The execution and delivery of the Agreement by Parent and
Parent Sub do not, and the performance of the Agreement and the Merger and the
Transactions contemplated thereby by Parent and Parent Sub will not, require
any Consent or permit of, or filing with or notification to, any federal or
Delaware Governmental Authority, except the filing and recordation of an
appropriate Certificate of Merger with the Secretary as required by Delaware
Law.

         6.      Upon the issuance of a Certificate of Merger by the Secretary,
the Merger will become effective in accordance with the Agreement and the
Delaware Law, and each issued and outstanding share of Target Stock (other than
Dissenting Shares) will be converted into the consideration provided in Section
2.01 of the Agreement.

         7.      To the best of our knowledge, except as set forth in the
Parent Disclosure Schedule, no Proceedings are pending or Threatened against
Parent or Parent Sub seeking to prevent or delay the Merger or the Transactions
contemplated by the Agreement or challenging any of the terms or provisions of
the Agreement or seeking material damages in connection therewith.

The preceding opinions and "negative assurance" statements are subject to the
following qualifications and limitations:

         A.      In connection with statements herein qualified by "to our
knowledge" or as to matters that have "come to our attention," our examination
has been limited to discussions with the officers and other representatives of
Parent and Parent Sub by, and those statements refer only to what is in the
actual knowledge of, attorneys in the Dallas, Chicago and Washington D.C.
offices of this Firm who have been involved in the representation of Parent and
Parent Sub in connection with the Merger and the Transactions described in the
Agreement, and we have made no independent investigations as to the accuracy or
completeness of any of the representations, warranties, data or other
information, written or oral, made or furnished by Target or the Target
Subsidiaries to us or to you.

         B.       The opinions and statements expressed herein are limited to

         C.      With respect to the opinion expressed in Paragraph 7, we have
not conducted any search of any indexes, dockets or other records of any court

         D.      The opinions and statements expressed herein are rendered as
of the time immediately preceding the Effective Time, and we hereby disclaim
any obligation to advise you of, or to supplement any of our opinions or
statements because of, any changes in fact or Law which might affect any of
those opinions or statements.

         E.      We are licensed to practice law only in the State of Texas and
are therefore unable to render an opinion regarding the laws of any
jurisdiction other than the State of Texas. Accordingly, for purposes of this
opinion we have assumed that the laws of the State of Texas and Delaware or any
other jurisdiction that is the subject of this opinion are the same.
Notwithstanding the foregoing, we are able to render an opinion with respect to
any matter covered by this opinion that is governed or controlled by Delaware
Law and accordingly our opinion is not subject to the foregoing limitation to
the extent it relates to Delaware Law.

         F.      This opinion letter is solely for your benefit in connection
with the Merger and the Transactions described in the Agreement and may not be
relied upon, quoted or otherwise used by any other person or entity or for any
other purpose without our express written consent.


                                        Very truly yours,

         Each Option and Cash Payment granted hereunder shall be evidenced by

SECTION 6.       TERMS AND CONDITIONS OF OPTIONS AND CASH PAYMENTS.

         All Options and Cash Payments granted hereunder shall comply with, be

         6.1     NUMBER OF SHARES. Each Agreement shall provide for the grant
of Options to an Eligible Individual to purchase a number of shares of Stock,
subject to the adjustments provided for in Section 6.9 hereof, equal to the
product of (a) the Aggregate Option Shares and (b) the Percentage Participation
allocated to such Eligible Individual.

         6.2     VESTING OF OPTIONS.

         (a)     Subject to the provisions of Section 6.8 hereof, the Options
granted to an Eligible Individual shall be eligible for vesting at the end of
each of the Fiscal Years of the Corporation ending December 31, 1998 to
December 31, 2001 as provided in this Section 6.2(a). The number of Options
that shall vest (the "Annual Option Vesting Amount") at the end of the Fiscal
Years of the Corporation ending December 31, 1998 through December 31, 2001
shall equal the product of (i) the Aggregate Option Amount with respect to such
Fiscal





                                      E-6
<PAGE>   94
Year times (ii) the Applicable Percentage with respect to such Fiscal Year.
Notwithstanding anything contained herein to the contrary, the Annual Option
Vesting Amount shall be zero in any Fiscal Year in which the Attained

of Options granted to an Eligible Individual that shall vest with respect to
each Fiscal Year of the Corporation ending December 31, 1998 through December
31, 2001 shall be an amount equal to the Percentage Participation of such
Eligible Individual with respect to that Fiscal Year times the Annual Option
Vesting Amount, if any, for that Fiscal Year. If the number of Options that
would vest according to the immediately preceding sentence exceeds the number
of Options granted to an Eligible Individual which have not yet vested, then
only those Options that have not yet vested shall vest according to this
Section 6.2(a). All Options that have not vested with respect to the Fiscal
Years ending December 31, 1998 through December 31, 2001 in accordance with
this Section 6.2(a) shall vest on December 31, 2002.

         (b)     An Eligible Individual may not purchase the shares of Stock
subject to an Option until such time as that portion of the Option has vested
pursuant to this Section 6.2. Notwithstanding any other provision of this Plan,
including the provisions of Section 6.8 hereof, no Option shall be exercisable
after the fifth anniversary of the vesting date of such Option.

         6.3     EXERCISE PRICE OF OPTIONS. The exercise price per share of
Stock subject to an Option shall be the Closing Sales Price.

         6.4     CASH PAYMENTS. Each Agreement shall provide for the grant of
the right to Cash Payments to an Eligible Individual with respect to each
Fiscal Year of the Corporation ending December 31, 1998 and December 31, 1999
in an amount equal to the Percentage Participation of such Eligible Individual
with respect to that Fiscal Year times the Annual Payment Award, if any, for
that Fiscal Year. Each Cash Payment under this Section 6.4 shall be deemed
payable as of December 31 in respect of each Fiscal Year and the delivery of
any Cash Payment with respect to a Fiscal Year shall be made by the Corporation
not later than 75 days after the end of such Fiscal Year. The Corporation may,
in its discretion, withhold from the amount of any Cash Payment delivered to an
Eligible Individual the portion thereof that it deems necessary to satisfy its
obligation to withhold Federal, state or local income or other taxes incurred
by reason of such Cash Payment.

         6.5     DETERMINATION OF CELCORE REVENUES. For purposes of determining
the Annual Option Vesting Amount with respect to a Fiscal Year and the Annual
Payment Award with respect to a Fiscal Year, within 60 days after the end of
each Fiscal Year of the Corporation (i) from December 31, 1998 to December 31,
2001 with respect to the Annual Option Vesting Amount and (ii) December 31,
1998 and December 31, 1999 with respect to the Annual Payment Award, the
Corporation shall furnish the Committee with such financial information as it
shall require in order to determine the Celcore Revenues with respect to that
Fiscal Year, and the Committee shall make such determination in good faith as
soon as possible after the





                                      E-7

receipt of such information, which determination shall be final and binding on
all Eligible Individuals. Within 75 days after the end of each Fiscal Year of
the Corporation ending December 31, 1998 to December 31, 2001, the Committee
shall notify each Eligible Individual with respect to whom an Option is
eligible for vesting for that Fiscal Year of the determination of the Celcore
Revenues for that Fiscal Year and the number of shares of Stock subject to such
Eligible Individual's Option which has vested with respect to that Fiscal Year,
together with delivery of the Cash Payment, if any, with respect to that Fiscal
Year.

         6.6     MEDIUM AND TIME OF PAYMENT, METHOD OF EXERCISE, AND
WITHHOLDING TAXES. The exercise price of an Option shall be payable upon the
exercise of the Option in cash or by check payable to the order of the
Corporation. Exercise of an Option shall not be effective until the Corporation
has received written notice of exercise. Such notice must specify the number of
whole shares of Stock to be purchased and be accompanied by payment in full of
the aggregate exercise price of the number of shares purchased. The Corporation
shall not in any case be required to sell, issue, or deliver a fractional share
with respect to any Option.

         The Committee may, in its discretion, require an Eligible Individual
to pay to the Corporation at the time of exercise of an Option or portion
thereof the amount that the Corporation deems necessary to satisfy its
obligation to withhold Federal, state or local income or other taxes incurred
by reason of the exercise.

         6.7     TERM, TIME OF EXERCISE, AND TRANSFERABILITY OF OPTIONS. In
addition to such other terms and conditions as may be included in a particular
Agreement granting an Option, during the term of an Option such Option shall be
exercisable during an Eligible Individual's lifetime only by him or by his
guardian or legal representative. An Option shall not be transferable other
than by will or the laws of descent and distribution. No Option shall be deemed
to satisfy the provisions of Section 422A of the Code. As soon as reasonably
practicable after the Corporation receives written notice that the Eligible
Individual has elected to exercise all or a portion of an Option which has
vested pursuant to the Plan, such notice to be accompanied by payment in full
of the aggregate Option price of the number of shares purchased, the
Corporation shall issue and deliver a certificate representing the shares
acquired in consequence of the exercise and any other amounts payable in
consequence of such exercise.

         Nothing herein or in any Option granted hereunder shall require the
Corporation to issue any shares upon exercise of any Option if such issuance
would, in the opinion of counsel for the Corporation, constitute a violation of
the Securities Act or any similar or superseding statute or statutes, any
applicable blue sky or state securities laws or any other applicable statute or
regulation, as then in effect. The Corporation shall file or cause to be filed
with the Securities and Exchange Commission at least twenty days prior to the
date of the notification to Eligible Individuals of that portion of the Options
which has vested with respect to the Fiscal Year ended December 31, 1998, a
Registration Statement on Form S-8 registering under





                                      E-8
<PAGE>   96
the Securities Act the Stock issuable upon exercise of the Options, and shall
keep such Registration Statement effective for so long as Options remain
outstanding and exercisable under this Plan or, if shorter, so long as such
Form S-8, or any successor form, remains available to the Corporation for
registration of such Stock. At the time of any exercise of an Option, in the
event such Registration Statement on Form S-8 or successor form is not
effective, the Corporation may, as a condition precedent to the exercise of
such Option, require from the Eligible Individual exercising such Option (or in
the event of his death, his legal representatives, heirs, legatees, or
distributees) such written representations, if any, concerning his intentions
with regard to the retention or disposition of the shares being acquired by
exercise of such Option and such written covenants and agreements, if any, as
to the manner of disposal of such shares as, in the opinion of counsel to the
Corporation, may be necessary to ensure that any disposition by such Eligible
Individual (or in the event of his death, his legal representatives, heirs,
legatees, or distributees), will not involve a violation of the Securities Act
or any similar or superseding statute or statutes, or any other applicable
state or federal statute or regulation, as then in effect.

         6.8     TERMINATION OF EMPLOYMENT, DEATH OR DISABILITY.

         (a)     If an Eligible Individual ceases to be employed by at least
one of the employers in the group of employers consisting of the Corporation
and its Affiliates because the Eligible Individual voluntarily terminates
employment with such group of employers, (i) the portion, if any, of an Option
that has not yet vested under the terms of the Plan, on the date of the
Eligible Individual's Termination of Service shall terminate as of such date,
(ii) the Eligible Individual shall have the right for thirty (30) days after
such Termination of Service to exercise the portion, if any, of the Option
which has vested pursuant to the Plan as of the date of the Eligible
Individual's Termination of Service, and thereafter such Option shall terminate
and cease to be exercisable, (iii) the portion of any Option which has vested
with respect to a Fiscal Year ending prior to the date of the Eligible
Individual's Termination of Service but with respect to which the Committee has
not yet determined the amount which has vested at the date of such termination
may be exercised by the Eligible Individual within thirty (30) days after (A)
the date of receipt by the Eligible Individual of the portion of any Cash
Payment which has vested with respect to such Fiscal Year, or (B) if no Cash
Payment is made with respect to such Fiscal Year, the date of receipt by the
Eligible Individual of a notice from the Committee pursuant to Section 6.5
hereof of the number of shares of Stock subject to such Eligible Individual's
Option which has vested with respect to that Fiscal Year, and thereafter such
portion shall terminate and cease to be exercisable, and (iv) the portion of
any Cash Payment granted to the Eligible Individual which is payable with
respect to a Fiscal Year ending prior to the date of the Eligible Individual's
Termination of Service shall be paid to such Eligible Individual at the time
provided for in this Plan, and no other Cash Payment shall be required to be
paid by the Corporation in connection with this Plan. Notwithstanding the
foregoing, if an Eligible Individual ceases to be employed during the Fiscal
Year because the Eligible Individual voluntarily terminates employment as
provided in this Section 6.8(a), no





                                      E-9
<PAGE>   97
Cash Payment for such Fiscal Year shall be payable to the Eligible Individual
and no Options shall vest in respect of such Fiscal Year.

         (b)     If an Eligible Individual ceases to be employed by at least
one of the employers in the group of employers consisting of the Corporation
and its Affiliates because any of such entities terminates the Eligible
Individual's employment for Cause, (i) the portion, if any, of an Option that
remains unexercised, including that portion, if any, that has vested under the
terms of the Plan, on the date of the Eligible Individual's Termination of
Service, shall terminate and cease to be exercisable as of such date, and (ii)
the right of such Eligible Individual to any Cash Payment which has not been
paid prior to the date of the Eligible Individual's Termination of Service
shall be terminated.

         (c)     If an Eligible Individual ceases to be employed by at least
one of the employers in the group of employers consisting of the Corporation
and its Affiliates because one or more of such entities terminates the
employment of the Eligible Individual but not for Cause, (i) subject to Section
6.8(f) below, the portion, if any, of an Option that has not yet vested under
the terms of the Plan, on the date of the Eligible Individual's Termination of
Service shall terminate as of such date, (ii) subject to Section 6.8(f) below,
such Eligible Individual shall be entitled to exercise the Option to the extent
that such Eligible Individual was entitled to exercise it on such date, but
only until the earlier of the date (A) the Option held by such Eligible
Individual expires, or (B) six (6) months after the date of the Termination of
Services of such Eligible Individual, and (iii) subject to Section 6.8(f)
below, such Eligible Individual shall receive a Cash Payment pursuant to
Section 2.2 hereof.

         (d)     Notwithstanding the provisions of Sections 6.8(a), (b) and (c)
above, if an Eligible Individual ceases to be employed by at least one of the
employers in the group of employers consisting of the Corporation and its
Affiliates by reason of Permanent and Total Disability, (i) subject to Section
6.8(f) below, the portion, if any, of an Option that has not yet vested under
the terms of the Plan on the date of the Eligible Individual's Termination of
Service due to such Permanent and Total Disability shall terminate as of such
date, (ii) subject to Section 6.8(f) below, notwithstanding such Termination of
Service, such Eligible Individual may exercise an Option in whole or in part to
the extent such Option was exercisable on the date of Termination of Service of
such Eligible Individual due to such Permanent and Total Disability, but only
until the earlier of the date (A) the Option held by the Eligible Individual
expires, or (B) twelve (12) months from the date of Termination of Service of
such Eligible Individual due to such Permanent and Total Disability, and (ii)
subject to Section 6.8(f) below, such Eligible Individual shall be eligible to
receive a Cash Payment pursuant to Section 2.2 hereof.

         (e)     Upon the death of an Eligible Individual, (i) any Option held
by an Eligible Individual shall terminate and be of no further effect;
provided, however, notwithstanding the provisions of Sections 6.8(a), (b) and
(c) above and subject to Section 6.8(f) below, if an Eligible Individual dies
while in the employ of the Corporation or an Affiliate, such legal





                                      E-10
<PAGE>   98
representatives, heirs, legatees, or distributees shall have the right to
exercise such Options in accordance with this Plan and such Eligible
Individual's Agreement to the extent such Options had vested at the time of
such Eligible Individual's death, but only until the earlier of the date (A)
the Option held by the Eligible Individual expires, or (B) twelve (12) months
from the date of the Eligible Individual's death, and (ii) subject to Section
6.8(f) below, the Eligible Individual's legal representatives, heirs, legatees,
or distributees shall be eligible to receive a Cash Payment pursuant to Section
2.2 hereof.

         (f)     Unless otherwise determined by the Committee or required by
applicable law, in the event during the Fiscal Year an Eligible Individual
ceases to be employed by at least one of the employers in the group of
employers consisting of the Corporation and its Affiliates because one or more
of such entities terminates the employment of such Eligible Individual but not
for Cause, or by reason of death or Permanent and Total Disability of such
Eligible Individual that occurs:

                 (i)      if such Eligible Individual is otherwise entitled to
         receive a Cash Payment under Section 2.2 hereof for such Fiscal Year
         but for the fact the Eligible Individual is no longer employed, the
         Eligible Individual (or the Eligible Individual's legal representative
         or beneficiary) shall receive a Cash Payment equal to the product of
         (i) the Cash Payment he/she would have received for such entire Fiscal
         Year, multiplied by (ii) a fraction, the numerator of which is the
         number of days during such Fiscal Year in which the Eligible
         Individual was an employee of the Corporation or its Affiliates, and
         the denominator of which is the number of days in such Fiscal Year;
         and

                 (ii)     if an Option would otherwise vest under Section 6.2
         hereof, the Annual Option Vesting Amount allocable to such Eligible
         Individual based on his Percentage Participation shall be adjusted
         such that the number of Options granted to such Eligible Individual
         that shall vest with respect to such Fiscal Year shall be equal to the
         product of (i) the Annual Option Vesting Amount that would have been
         allocable to such Eligible Individual for such entire Fiscal Year,
         multiplied by (ii) a fraction, the numerator of which is the number of
         days during such Fiscal Year in which the Eligible Individual was an
         employee of the Corporation or its Affiliates, and the denominator of
         which is the number of days in such Fiscal Year.

         6.9     ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, MERGER, ETC.
Notwithstanding any other provision hereof, in the event of any change in the
number of outstanding shares of Stock effected without receipt of consideration
therefor by the Corporation, by reason of a stock dividend, or split,
combination, exchange of shares of other recapitalization, merger, or
otherwise, in which the Corporation is the surviving corporation, the aggregate
number and class of the reserved shares, the number and class of shares subject
to each outstanding Option and the exercise price of each outstanding Option
shall be automatically adjusted to accurately and equitably reflect the effect
thereon of such change,





                                      E-11
<PAGE>   99
provided that any fractional share resulting from such adjustment may be
eliminated, and provided further that the exercise price of an Option shall not
be less than $.01 per share. In the event of a dispute concerning such
adjustment, the decision of the Committee made in good faith shall be
conclusive. Neither this Plan nor any Agreement shall affect the right of the
Corporation or any Affiliate thereof to reclassify, recapitalize or otherwise
change its capital or debt structure or to merge, consolidate, convey any or
all of its assets, dissolve, liquidate, wind up, or otherwise reorganize.

         In the event of (a) a dissolution or liquidation of the Corporation,
(b) a merger or consolidation (other than a merger effecting a reincorporation
of the Corporation in another state or other jurisdiction or any other merger
or a consolidation in which the stockholders of the surviving corporation and
their proportionate interests therein immediately after the merger or
consolidation are substantially identical to the stockholders of the
Corporation and their proportionate interests therein immediately prior to the
merger or consolidation) in which the Corporation is not the surviving
corporation (or survives only as a subsidiary of another corporation in a
transaction in which the stockholders of the parent of the Corporation and
their proportionate interests therein immediately after the transaction are not
substantially identical to the stockholders of the Corporation and their
proportionate interests therein immediately prior to the transaction; provided
that the Board of Directors may at any time prior to such merger or
consolidation provide by resolution that the foregoing provisions of this
parenthetical shall not apply if a majority of the board of directors of such
parent immediately after the transaction consists of individuals who
constituted a majority of the Board of Directors immediately prior to the
transaction), or (c) a transaction in which any person becomes the owner of 50%
or more of the total combined voting power of all classes of stock of the
Corporation (provided that the Board of Directors may at any time prior to such
transaction provide by resolution that this Subparagraph (c) shall not apply if
such acquiring person is a corporation and a majority of the board of directors
of such corporation immediately after the transaction consists of individuals
who constituted a majority of the Board of Directors immediately prior to the
acquisition of such 50% or more total combined voting power), every Option then
outstanding shall terminate, but the holders of each such then outstanding
Option shall, in any event, have the right, immediately prior to such
dissolution, liquidation, merger, consolidation, or transaction, to exercise
such Options, to the extent not theretofore exercised, without regard to the
vesting provisions of Section 6.2 hereof if (and only if) such Options have not
at that time expired or been terminated pursuant to Section 6.8 hereof. Such
acceleration of exercisability shall not apply to a given Option if any
surviving or acquiring corporation agrees to assume such Option in connection
with the merger, consolidation, or transaction, in which event such Options
will continue to be subject to the vesting provisions of Section 6.2 hereof.

         6.10    RIGHTS AS A STOCKHOLDER. An Eligible Individual shall have no
right as a stockholder with respect to any shares covered by his Option until a
certificate representing such shares is issued to him. No adjustment shall be
made for dividends (ordinary or extraordinary, whether in cash or other
property) or distributions or other rights for which the





                                      E-12
<PAGE>   100
record date is prior to the date such certificate is issued, except as provided
in Section 6.9 hereof.

         6.11    FURNISH INFORMATION. Each Eligible Individual shall furnish to
the Corporation all information requested by the Corporation to enable it to
comply with any reporting or other requirement imposed upon the Corporation by
or under any applicable statute or regulation.

         6.12    OBLIGATION TO EXERCISE. The granting of an Option hereunder
shall impose no obligation upon the Eligible Individual to exercise the same or
any part thereof.

SECTION 7.       GENERAL.

         7.1     APPLICATION OF FUNDS; ISSUANCE OF SHARES. The proceeds
received by the Corporation from the sale of shares pursuant to Options shall

authorized, validly issued, fully paid and nonassessable.

         7.2     RIGHT OF THE CORPORATION AND AFFILIATES TO TERMINATE
EMPLOYMENT. Nothing contained in this Plan, or in any Agreement, shall confer

Corporation or any Affiliate to terminate or modify in any way the terms,
including but not limited to the compensation and responsibilities, of the
Eligible Individual's employment at any time. Nothing contained herein shall be
deemed to require any action on the part of the Committee or the Board of
Directors of the Corporation or any Affiliate in connection with the
termination of employment of an Eligible Individual.

         7.3     NO LIABILITY FOR GOOD FAITH DETERMINATIONS. Neither the
members of the Board of Directors nor any member of the Committee shall be
liable for any act, omission, or determination taken or made in good faith with
respect to this Plan or any Option or right to Cash Payment granted under it,
and members of the Board of Directors and the Committee shall be entitled to
indemnification and reimbursement by the Corporation in respect of any claim,
loss, damage, or expense (including attorneys' fees, the costs of settling any
suit, provided such settlement is approved by independent legal counsel
selected by the Corporation, and amounts paid in satisfaction of a judgment,
except a judgment based on a finding of bad faith) arising therefrom to the
full extent permitted by law and under any directors and officers liability or
similar insurance coverage that may from time to time be in effect.

         7.4     OTHER BENEFITS. Participation in the Plan shall not preclude
the Eligible Individual from eligibility in any other stock option plan of the
Corporation or any Affiliate or any old age benefit, insurance, pension, profit
sharing retirement, bonus, or other extra





                                      E-13
<PAGE>   101
compensation plans which the Corporation or any Affiliate has adopted, or may,
at any time, adopt for the benefit of its employees.

issuance or transfer of shares of Stock to the Eligible Individual, or to his
legal representatives, heir, legatee, or distributee, in accordance with the
provisions hereof, shall, to the extent thereof, be in full satisfaction of all
claims of such persons with respect to such payment, issuance or transfer
hereunder. The Committee may require any Eligible Individual, legal
representative, heir, legatee, or distributee, as a condition precedent to such
payment, to execute a release and receipt therefor in such form as it shall
determine.

Corporation guarantees the Stock of the Corporation from loss or depreciation.

         7.7     SEVERABILITY. If any provision of this Plan is held to be
illegal or invalid for any reason, the illegality or invalidity shall not
affect the remaining provisions hereof, but such provision shall be fully
severable and this Plan shall be construed and enforced as if the illegal or
invalid provision had never been included herein.

            DSC COMPLETES ACQUISITION OF CELCORE FOR PRIMARILY CASH

Dallas, December 4, 1997 ... DSC Communications Corporation announced today the
completion of the acquisition of Celcore, Inc. for approximately $145 million
in cash and the assumption of Celcore's outstanding stock options.  The
acquisition of the Memphis-based GSM and AMPS mobile wireless systems
manufacturer follows the signing of a definitive agreement announced in late
October of this year.

Originally DSC had offered its common stock for all outstanding shares of
Celcore.  Both parties subsequently agreed to the cash acquisition.  The total
purchase price is estimated to be approximately $167 million, which includes
the cash consideration, the value of assumed stock options and estimated
transaction costs.

Approximately $135 million of the total purchase price will be written off as
in-process research and development in the fourth quarter of 1997.  The
remaining excess of purchase price over net assets acquired will be accounted
for as costs in excess of net assets of businesses acquired and amortized over
its estimated useful life.

Celcore designs and develops cost-effective wireless telecommunication systems
for cellular and PCS applications in low teledensity markets.  Its technology
development center will remain in Memphis and will be known as the company's
cellular infrastructure division.

DSC Communications is a global provider of advanced telecommunications
products, including digital switching, transmission, access and network
management systems.  DSC's integrated network solutions support voice, data and
broadband services, such as intelligent networking, wireless and switched
digital voice applications.  DSC had 1996 annual revenues of approximately
$1.4 billion and is active in more than 60 countries worldwide.
