ITEM 1.  SECURITY AND ISSUER

         This statement relates to the common stock, par value $.01 per share
(the "Common Stock"), of SSE Telecom, Inc., a Delaware corporation (the
"Company").  The principal executive offices of the Company are located at 8230
Leesburg Pike, Suite 710, Vienna, Virginia 22182.


ITEM 2.  IDENTITY AND BACKGROUND

         This statement is being filed by Alcatel Telspace, a societe anonyme
organized under the laws of France ("Alcatel"), in connection with Alcatel's
acquisition of (a) 625,000 shares of Common Stock (the "Stock"), and (b) a
warrant exercisable for 300,000 additional shares of Common Stock (the
"Warrant").  The address of Alcatel's principal business and the address of
Alcatel's principal office is 5 rue Noel PONS, 92734 NANTERRE Cedex, France.
Alcatel's principal business is the design, manufacture, assembly and sale of
satellite and microwave telecommunications systems.  During the last five years,
Alcatel has, to its knowledge, neither been convicted in a criminal proceeding
(excluding traffic violations or similar misdemeanors), nor been a party to a
civil proceeding of a judicial or administrative body of competent jurisdiction,
as a result of which Alcatel was or is subject to a judgment, decree or final
order enjoining further violations of, or prohibiting or mandating activities
subject to, federal or state securities laws or finding any violations with
respect to such laws.


ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

         Alcatel paid cash, in an aggregate amount of $7,826,510.00, for the
Stock and the Warrant and the source of the cash was the working capital of
Alcatel.


ITEM  4.  PURPOSE OF TRANSACTION

         Alcatel acquired the Stock and the Warrant for general investment
purposes.  Alcatel intends to review on a continuing basis its investment in
the Company.  See Item 6 below, which is incorporated herein by reference, for
a description of certain board representation and observation rights granted to
Alcatel.  As of the date of this Schedule 13D, no determination has been made
by Alcatel to acquire additional securities of the Company, to dispose of any
of the shares of the Stock that Alcatel currently owns, to transfer the
Warrant, in whole or part, or to exercise the Warrant, in whole or part,
although it reserves the right to decide to take any of such actions in the
future.  Any such





                                     - 3 -

determination will depend on market conditions prevailing from time to time,
and on other conditions which may be applicable depending on the nature of the
transaction or transactions involved.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

         (a)   Alcatel currently owns 625,000 shares of Common Stock and the
Warrant represents the right to purchase 300,000 additional shares of Common
Stock at any time prior to September 6, 1999.  The 925,000 shares of Common
Stock reported as beneficially owned by Alcatel represents, as of the date
hereof, approximately 14.32% of the issued and outstanding shares of Common
Stock.

         (b)     Alcatel has sole voting power of all of the shares of Common
Stock that it currently owns and, except for the limitations set forth in the
Stockholder Agreement (as defined in Item 6 below and incorporated herein by
reference), Alcatel has sole disposition power of all of the shares of Common
Stock that it currently owns.

respect to the Stock and the shares of Common Stock issuable upon exercise of 
the Warrant.

thereto.  In addition, the Company granted to Alcatel, subject to the
limitations set forth in the Stockholder Agreement, the ability to designate
an individual (the "Alcatel Designee") for nomination to the Company's board of
directors (the "Board") and the parties thereto agreed, subject to the

<PAGE>   27

         breach of or default under any such Contract (or with notice or lapse
         of time or both, would be in violation or breach of or default under

         effect on the Business.

Subsidiaries.

         SECTION 3.14 Compliance.  Neither the Company nor any of its
Subsidiaries is in breach or violation of any provision of its certificate of

violations and defaults, would have a material adverse effect on the Business.
The Company and its Subsidiaries have obtained and are in compliance with all
Licenses required to be obtained by them in connection with the operation of the
Business.

         SECTION 3.15 Employee Benefits.

                 (a)      Compliance.  Each Benefit Plan (and each related
         trust or insurance contract) complies in form and in operation in all
         material respects with its respective governing documents and the
         applicable requirements of ERISA and the Code.  The Company and each
         of its Subsidiaries have performed all material obligations required
         to be performed by them under, and are not in material default under
         or in material violation of any term, provision, or condition of, any
         Benefit Plan.

                 (b)      Filings.  All required reports and descriptions
         (including without limitation Form 5500 Annual Reports, Summary Annual
         Reports, PBGC-1's, and Summary Plan Descriptions) have been filed or
         distributed in a timely manner with respect to each Benefit Plan.

                 (c)      Contributions.  All contributions (including all
         employer contributions and employee salary reduction contributions)
         which are due have been paid to each Benefit Plan and all
         contributions for any period ending on or before the Closing Date
         which are not yet due have been paid to each Benefit Plan or accrued
         in accordance with the past custom and practice of the Company and its
         Subsidiaries.  All premiums or other payments for all periods ending
         on or before the date hereof have been paid with respect to each
         Welfare Benefit Plan (as defined in ERISA Section 3(1)).

                 (d)      Determination Letters.  Each Pension Benefit Plan
         which is required to comply with Code Section 401(a) satisfies the
         requirements of Code Section 401(a) and has received a favorable
         determination letter from the IRS regarding such status and has not,
         since receipt of the most recent favorable determination letter, been
         amended or operated in a way which would adversely affect such
         qualified status.

                 (e)      Asset Valuation.  The market value of assets under
         each Pension Benefit Plan (other than any Multiemployer Plan) equals
         or exceeds the present value of accrued benefits thereunder through
         the date hereof (determined on a plan termination basis).  No Pension
         Benefit Plan (other than any Multiemployer Plan) has been completely
         or partially terminated or been the subject of a reportable event as
         to





                                     - 17 -
<PAGE>   29

         which notices would be required to be filed with the PBGC.  No
         proceeding by the PBGC to terminate any Pension Benefit Plan (other
         than any Multiemployer Plan) has been instituted or, to the Knowledge
         of the Company, threatened.

                 (f)      No Prohibited Transactions.  To the Knowledge of the
         Company, there has been no Prohibited Transaction (as defined in ERISA
         Section 406 and Code Section 4975) with respect to any Benefit Plan.

                 (g)      Claims.  There are no actions, suits, arbitrations,
         or claims pending (other than routine claims for benefits) or, to the
         Knowledge of the Company, threatened against any Benefit Plan, its
         administrators, trustees, or other fiduciaries, or against the Company
         or any of its Subsidiaries, or against the assets of such Plan.  To
         the Knowledge of the Company, no fiduciary with respect to any Benefit
         Plan has any material Liability for breach of fiduciary duty or any
         other failure to act or comply in connection with the administration
         or investment of the assets of any Benefit Plan.

                 (h)      Miscellaneous.  Neither the Company nor any of its
         Subsidiaries is, and neither has ever been, a member of a controlled
         group of corporations that contributes to, ever has contributed to, or
         ever has been required to contribute to any multiemployer plan (as
         defined in Section 4001(a)(3) of ERISA) (a " Plan") and neither has
         any Liability (including withdrawal Liability) under any Multiemployer
         Plan.  Neither the Company nor any of its Subsidiaries has incurred,
         and neither has any reason to expect that it will incur, any Liability
         to the PBGC (other than PBGC premium payments) or otherwise under
         Title IV of ERISA (including any withdrawal Liability) or under the
         Code with respect to any Pension Benefit Plan that it, or any
         controlled group of corporations which includes it, maintain or have
         ever maintained or to which any of them contributes, has ever
         contributed, or has ever been required to contribute.  No Benefit Plan
         provides post-retirement welfare benefits other than continuation
         coverage provided pursuant to Part 6 of Title I of ERISA and Section
         4980A of the Code.  No Benefit Plan is under audit or, to the
         Knowledge of the Company, investigation by any Governmental Authority. 
         Each Benefit Plan which is a "group health plan" (as such term is
         defined in Section 4980B(g)(2) of the Code or ERISA Section 607(1))
         has been operated in material compliance with the provisions of Part 6
         of Title I of ERISA and Sections 4980A and 4980B of the Code at all
         times.

         SECTION 3.16 Insurance.  The Company and its Subsidiaries maintain,
with respect to the Business, insurance in such amounts and covering such risks
as is customary in the industry in which the Business operates.  Each such
policy of insurance is in full force and effect, and all premiums thereunder or
self-insurance funding amounts required thereby, as the case may be, have been
paid or funded. Neither the Company nor any of its Subsidiaries has received any
notice of termination with respect to any such insurance policy and is not in
default thereunder in any material respect.  No insurance carrier has threatened
to terminate any such insurance policy or to increase any premiums in respect
thereof, and neither the Company nor any of its Subsidiaries has failed to
comply with any material conditions contained in any such policy.

         SECTION 3.17 Environmental Matters.

                 (a)      Compliance.  Each of the Company and its Subsidiaries
         has obtained, and complied with all the terms and conditions of, all
         Licenses required by any Environmental Law in connection with the
         Business except where the failure to obtain or comply with any such
         License would not have, individually or in the aggregate with other
         such failures, a material adverse effect on the Business.  Each such
         License is in full force and effect.  Each of the Company and its
         Subsidiaries is in compliance with all Environmental Laws except where
         a failure to comply, individually or in the aggregate with all such
         other failures, would not have a material adverse effect on the
         Business.

                 (b)      Listings.  Except as disclosed in Schedule 3.17(b),
         to the Knowledge of the Company, none of the real property owned or
         leased by the Company or any of its Subsidiaries is listed on the NPL,
         CERCLIS or any similar state or local list of sites requiring
         investigation or clean-up.

                 (c)      No Notice.  No written notice or, to the Knowledge of
         the Company, any other communication from any Governmental Authority
         of any alleged violation of any Environmental Law has been received by
         the Company or any of its Subsidiaries, except for notices or
         communications that have been complied with in all respects.

                 (d)      No Hazardous Substances.  Neither the Company nor any
         of its Subsidiaries utilizes any Hazardous Substances in the course of
         its Business operations and there has been no release of Hazardous
         Substances by the Company or any of its Subsidiaries or, to the
         knowledge of the Company, any other Person, on any property, owned or
         occupied by the Company or any of its Subsidiaries.

         SECTION 3.18 Offer or Sale of Shares and Warrant.  Neither the Company
nor anyone acting on its behalf has offered the Stock or Warrant to any entity
other than the Purchaser or has taken any other action that would subject the
issuance and sale of the Stock or Warrant (or the issuance of the Common Stock
upon exercise of the Warrant) to the registration requirements of the Securities
Act or any state securities Laws.

         SECTION 3.19 Brokers.  No broker or other representative has acted on
behalf of the Company or any of its Subsidiaries in connection with the
transactions contemplated hereby in such manner as to give rise to any valid
claim by any Person against the Purchaser for a finder's fee, brokerage
commission or similar payment.

         SECTION 3.20 Transactions With Directors, Officers, Employees and
Affiliates.  Except as set forth in Schedule 3.20 there have been no
transactions between the Company or any of its Subsidiaries and any director,
officer, employee or affiliate (as defined in Rule 405 promulgated by the SEC)
of the Company or any of its Subsidiaries, except on an arm's length basis in
accordance with normal business practices, and none of the officers, directors,
employees or affiliates of the Company or any of its Subsidiaries, or any member
of the immediate family of any such Persons, is a director or officer of, or has
a material interest

in, any Person which is a material supplier, customer or sales agent of the
Company or any of its Subsidiaries or has competed to a material extent with
the Company or any of its Subsidiaries.  Except as set forth in Schedule 3.20,
no Affiliate of the Company or any of its Subsidiaries provides or supplies
assets, services or facilities which are individually or in the aggregate
material to the Business, and neither the Company nor any of its Subsidiaries
provides or supplies any assets, services or facilities to any Affiliate of the
Company or any of its Subsidiaries which are individually or in the aggregate
material to the Business.  Except as disclosed on Schedule 3.20, each of the
transactions listed in Schedule 3.20 is engaged in on an arm's-length basis.

and warranties of the Company herein in connection with the purchase by the
Purchaser of shares of Common Stock from the Selling Stockholders pursuant to
the Selling Stockholder Agreement.

<PAGE>   32

been duly authorized by all necessary corporate action on the part of the
Purchaser, and this Agreement has been, and at Closing the Transaction
Documents will be, duly executed and delivered by the Purchaser.  This
Agreement constitutes, and the Transaction Documents and all other instruments
and documents to be executed and delivered by the Purchaser hereunder will,
when executed and delivered, constitute, the legal valid and binding
obligations of the Purchaser enforceable against the Purchaser in accordance
with their respective terms, except that such enforcement (i) may be limited by
bankruptcy, insolvency, moratorium or similar laws affecting creditors' rights
generally, and (ii) is subject to the availability of equitable remedies, as
determined in the discretion of the court before which such a proceeding may be
brought.

         SECTION 4.3  Consents; No Conflict.  The Purchaser is not required to
obtain the consent, authorization or approval of any Person, or any License
from any Governmental Authority, as a condition to the consummation of this
Agreement or the Transaction Documents by the Purchaser.  The execution and
delivery of this Agreement and the Transaction Documents by the Purchaser and
the consummation of the transactions contemplated hereby and thereby will not
conflict with, result in the termination of, contravene or constitute a default
under, or be an event which with the giving of notice or passage of time or
both will become a default under, or give to others any rights of termination
or cancellation of, or accelerate the performance required by or maturity of,
or result in the creation of any material Lien or loss of any rights with
respect to the Purchaser pursuant to any of the terms, conditions or provisions
of or under, any applicable Law, the certificate of incorporation or by-laws
(or other organizational documents) of the Purchaser, or any Contract to which
the Purchaser is a party or which is otherwise binding upon the Purchaser or to
which the Assets of the Purchaser are subject.

         SECTION 4.4  Brokers.  No broker or other representative has acted on
behalf of the Purchaser in connection with the transactions contemplated hereby
in such manner as to give rise to any valid claim by any Person against the
Company for a finder's fee, brokerage commission or similar payment.

         SECTION 4.5  Purchase Entirely for Own Account.  The Purchaser will
acquire the Stock and the Warrant for investment for its own account, not as a
nominee or agent, and not with a view to the resale or distribution of any part
thereof, and the Purchaser has no present intention of selling, granting any
participation in, or otherwise distributing the Stock or the Warrant.  The

third Person with respect to the Stock or the Warrant.

representations as expressed herein.  The Purchaser has not been formed for the
specific purpose of acquiring the Stock or the Warrant.

<PAGE>   33

         SECTION 4.7  Restricted Securities.  The Purchaser understands that
the Stock and the Warrant are characterized as "restricted securities" under
the federal securities Laws inasmuch as they are being acquired in a
transaction not involving a public offering and that under such Laws, the Stock
and the Warrant may be resold without registration under the Securities Act
only in certain limited circumstances.  In this respect, the Purchaser
represents that it is familiar with Rule 144 promulgated under the Securities
Act ("Rule 144"), as presently in effect, and understands the resale
limitations imposed thereby and by the Securities Act.

         SECTION 4.8  Disclosure.  The representations and warranties of the
Purchaser contained in this Agreement and in any schedule, certificate or
agreement furnished by the Purchaser to the Company pursuant to this Agreement
do not contain any untrue statement of a material fact or omit to state a

light of the circumstances under which they were made, not misleading.

                             ADDITIONAL AGREEMENTS

         SECTION 5.1  Limitations on Disposition of Stock.  Without in any way
limiting the representations set forth in Article IV hereof, the Purchaser
agrees not to dispose of all or any portion of the Stock unless and until:  (i)
there is then in effect a registration statement under the Securities Act
covering such proposed disposition and such disposition is made in accordance
with such registration statement; or (ii)  (A) the Purchaser shall have
notified the Company of the proposed disposition and shall have furnished the
Company with a detailed statement of the circumstances surrounding the proposed
disposition, and (B) if reasonably requested by the Company, the Purchaser
shall have furnished the Company with an opinion of counsel, reasonably
satisfactory to the Company, that such disposition will not require
registration under the Act, provided that no opinion of counsel will be

<PAGE>   34

         (c)     Any legend required by the Blue Sky laws of any other state to
the extent such laws are applicable to the shares represented by the
certificate so legended.

         SECTION 5.3  Proceeds of Sale of Stock.  The Company shall use all of
the proceeds obtained from the sale of the Stock to the Purchaser, net of the
customary expenses associated therewith, solely to fund the working capital
needs of the Company and its Subsidiaries and/or to make the prepayment on the
Echostar Debenture required by Section 5.4.

         SECTION 5.4  Echostar Situation.  As a prepayment of the Echostar
Debenture, at Closing, the Company will pay to Echostar the amount of
$3,500,000.00 in principal plus all accrued interest on the Echostar Debenture
via wire transfer of immediately available funds to the account designated by
Echostar.  The Company shall not amend or terminate the Echostar Letter without
the prior written consent of the Purchaser which may be withheld in the sole
discretion of the Purchaser.  The Company shall take all action within its
power to limit to no more than 500,000 shares the number of shares of Common
Stock which Echostar would have the right to purchase at any time following
Closing pursuant to the Echostar Debenture or any warrants issued pursuant to
the Echostar Letter.  In the event Echostar acquires any Common Stock from the
Company, the Company shall use its best efforts to cause Echostar to execute
and deliver to the Company, the Purchaser and all other parties to the
Stockholder Agreement an agreement to be bound by all provisions thereof
binding on the stockholders of the Company which are parties thereto.

         SECTION 5.5  Delivery of Budgets and Other Information.  As long as
the Purchaser and its Affiliates, collectively, hold in the aggregate not less
than 500,000 shares of Common Stock or shares of Common Stock representing not
less than 8% of the outstanding shares of Common Stock on a fully diluted
basis, the Company shall deliver to the Purchaser (i) as soon as practicable,
but in any event at least thirty (30) days prior to the end of each fiscal year
of the Company, a budget and business plan for the next fiscal year for the
Business, prepared on a monthly basis, including balance sheets and sources and
applications of funds statements for such months and, as soon as prepared, any
other budgets or revised budgets prepared by the Company, (ii) such other
information relating to the financial condition, prospects or affairs of the
Business as the Purchaser may from time to time request, provided, however,
that the Company shall not be obligated to provide information which it deems
in good faith to be proprietary, and (iii) a copy of any Schedule 13D filing
made by any Person pursuant to Section 13(d) of the Exchange Act immediately
following the receipt thereof by the Company.

         SECTION 5.6  Access to Business.  Following the Closing, the Company
shall permit the Purchaser and its representatives at the Purchaser's expense,
as long as the Purchaser and its Affiliates, collectively, hold in the
aggregate not less than 500,000 shares of Common Stock or shares of Common
Stock representing not less than 8% of the outstanding shares of Common Stock
on a fully diluted basis, to visit and inspect the properties and Assets of the
Company and its Subsidiaries, to examine the books of account and records of
the Company and its Subsidiaries and to discuss the affairs, finances and
accounts of the Company and its Subsidiaries with the officers thereof, all at
such reasonable times as may be requested by the Purchaser, provided that the
Purchaser acknowledges that the access by the Purchaser to





                                     - 23 -
<PAGE>   35

certain information relating to Contracts which the Company has entered into
with United States Governmental Authorities may be restricted pursuant to
certain Laws due to the status of the Purchaser as a foreign corporation.

         SECTION 5.7  Right of First Offer.  Subject to the terms and
conditions in this Section 5.7, the Company hereby grants to the Purchaser the
following rights of first offer with respect to future sales by the Company of
its New Securities:

         (a)     Notice to Purchaser.  In the event the Company proposes to
issue New Securities, the Company shall give the Purchaser written notice (the
"First Offer Notice") of its intention stating (i) a description of the New
Securities which the Company proposes to issue and the identity of the Person
or group of Persons to whom the New Securities would be issued, (ii) the number
of shares of New Securities which the Company proposes to issue, (iii) the
price per share at which, and other terms on which, the Company proposes to
issue such New Securities, and (iv) the number of shares of such New Securities
that the Purchaser has the right to purchase under this Section 5.7, based on
the Purchaser Percentage.

         (b)     Exercise Right.  Within thirty (30) days after the First Offer
Notice is given to the Purchaser, the Purchaser may elect to purchase, at the
price specified in the First Offer Notice, the number of shares of the New
Securities proposed to be issued by the Company multiplied by the Purchaser
Percentage.  The Purchaser may exercise such purchase right in whole or in
part.  An election to purchase shall be made in writing and must be given to
the Company within such thirty (30) day period. The closing of the sale of New
Securities by the Company to the Purchaser upon exercise of its rights under
this Section 5.7 shall take place simultaneously with the closing of the sale
of New Securities to third parties.

         (c)     Lapse of Right.  The Company shall have sixty (60) days after
the last date on which the Purchaser's right of first offer lapses to enter
into a Contract (pursuant to which the sale of New Securities covered thereby
shall be closed, if at all, within sixty (60) days from the execution thereof)
to sell the New Securities which the Purchaser did not elect to purchase under
this Section 5.7, provided that such sale must be at or above the price
specified in the First Offer Notice and upon terms not materially more
favorable to the purchaser of such securities than the terms specified in the
First Offer Notice.  In the event the Company does not enter into a Contract to
sell the New Securities within such sixty (60) day period (or does not sell and
issue New Securities in accordance with any such Contract within sixty (60)
days from the date thereof), the Company shall not thereafter issue or sell any
New Securities without first offering such New Securities to the Purchaser in
the manner provided in this Section 5.7.

         (d)     Termination of Right of First Offer.  This Section 5.7 shall
terminate upon the first to occur of the following:

                      (i)         The date on which the Purchaser and its
         Affiliates, collectively, hold in the aggregate less than 500,000
         shares of Common Stock, provided that on such date such shares so held
         represent less than 8% of the outstanding shares of Common Stock on a
         fully diluted basis.





                                     - 24 -
<PAGE>   36

                      (ii)        The failure of the Purchaser to elect to
         purchase all shares of New Securities which the Purchaser is entitled
         to purchase pursuant to Section 5.7(b) at any such time as the
         Purchaser may elect to make such purchase.

         SECTION 5.8  Special Purchase Rights.

                 (a)      Grant of Rights.  Notwithstanding any other provision
         of this Agreement, if the Company proposes to issue or sell any Voting
         Stock to a Restricted Investor, or if any underwriter in connection
         with a registered public offering proposes to issue or sell any Voting
         Stock to a Restricted Investor, the Purchaser shall have a right of
         first offer to purchase all shares of such Voting Stock to be issued
         to such Restricted Investor on the terms pursuant to which the Company
         or such underwriter proposes to issue or sell such Voting Stock to
         such Restricted Investor, provided that the underwriters of a
         registered public offering of Voting Stock by the Company shall not be
         deemed to propose to issue or sell any Voting Stock to a Restricted
         Investor unless the Company solicits or arranges for the solicitation
         of orders to purchase Voting Stock by a Restricted Investor from such
         underwriters in anticipation of or in connection with a registered
         public offering and, provided further, that the execution and
         performance of an underwriting agreement by the Company in connection
         with a registered public offering and the participation by officers of
         the Company in the normal and customary selling activities undertaken
         by the underwriters shall not, in and of themselves, be considered
         soliciting or arranging for the solicitation of orders to purchase
         Voting Stock.

                 (b)      Notice to Purchaser.  In the event the Company or
         such underwriter proposes to issue or sell Voting Stock to a
         Restricted Investor, which would be subject to the foregoing right of
         first offer, the Company shall give the Purchaser written notice (the
         "Voting Stock Notice") of its or such underwriter's intentions stating
         (i) a description of the Voting Stock proposed to be issued or sold
         and the identity of the Restricted Investor, (ii) the total number of
         shares of Voting Stock proposed to be issued or sold, and (iii) the
         price per share at which, and the other terms on which, such Voting
         Stock is proposed to be issued or sold.


                 (c)      Exercise by Purchaser.  Within thirty (30) days after
         the Voting Stock Notice is given to the Purchaser, the Purchaser may
         elect to purchase, at the price and on the terms specified in the
         Voting Stock Notice, all shares of Voting Stock proposed to be issued
         and sold to the Restricted Investor.  An election to purchase shall be
         made by the Purchaser in writing and must be given to the Company
         within such thirty (30) day period.  The election described herein
         shall constitute an irrevocable, legally binding obligation of the
         Purchaser to purchase the Voting Stock on the terms set forth in the
         Voting Stock Notice.  The closing of the sale of the Voting Stock by
         the Company to the Purchaser upon the exercise of its rights under
         this Section 5.8 shall take place within thirty (30) days following
         the date on which such election to purchase is made.

                 (d)      Termination of Special Purchase Rights.  This Section
         5.8 shall terminate upon the first to occur of the following:





                                     - 25 -
<PAGE>   37


                      (i)         The date on which the Purchaser and its
         Affiliates, collectively, hold less than 500,000 shares of Common
         Stock, provided that on such date such shares so held represent less
         than 8% of the outstanding shares of Common Stock on a fully diluted
         basis.

                      (ii)        The failure of the Purchaser to elect to
         purchase all shares of Voting Stock which the Purchaser is entitled to
         purchase pursuant to Section 5.8(c) at any such time as the Purchaser
         may elect to make such purchase.

         SECTION 5.9  Subsidiary Stock.  The Company shall not permit any
Subsidiary of the Company to issue or sell any capital stock of such Subsidiary
to any Person other than the Company without granting to the Purchaser rights
to purchase such capital stock which are substantially the same as the rights
of the Purchaser pursuant to Sections 5.7 and 5.8 hereof.  For purposes of this
Section 5.9, any transfer of capital stock of any Subsidiary of the Company by
the Company shall be deemed to be an issuance of such stock by such Subsidiary
to such transferee and shall be subject to this Section 5.9.

         SECTION 5.10 Confidential Treatment.  The Company will use its best
efforts to obtain confidential treatment of the Commercial Agreement (and all
Schedules thereto) in all public filings that include such document including,

         SECTION 8.4  Method of Asserting Claims.  All claims for
indemnification by any Indemnified Party under this Article VIII shall be
asserted and resolved as follows:

         (a)     Third Party Claims.  If any claim or demand in respect of
which an Indemnified Party might seek indemnity under this Article VIII is
asserted against such Indemnified Party by a Person other than the Company or
the Purchaser (a "Third Party Claim"), the Indemnified Party shall give written
notice and the details thereof including copies of all relevant pleadings,
documents and information (collectively a "Third Party Claim Notice") to the
Indemnifying Party within a period of thirty (30) days following the assertion
of the Third Party Claim against the Indemnified Party (the "Third Party Claim
Notice Period").  If the Indemnified Party fails to provide the Third Party
Claim Notice within the Third Party Claim Notice Period, the Indemnifying Party
will not be obligated to indemnify the Indemnified Party with respect to such
Third Party Claim to the extent that the Indemnifying Party's ability to defend
has been prejudiced by such failure of the Indemnified Party.  The Indemnifying
Party will notify the Indemnified Party within a period of thirty (30) days
after the receipt of the Third Party Claim Notice by the Indemnifying Party
(the "Third Party Claim Response Period"):

                      (i)         whether the Indemnifying Party disputes its
         liability to the Indemnified Party under this Article VIII with
         respect to such Third Party Claim; and

                      (ii)        whether the Indemnifying Party desires, at
         its sole cost and expense, to defend the Indemnified Party against
         such Third Party Claim.

         If the Indemnifying Party notifies the Indemnified Party within the
Third Party Claim Response Period that the Indemnifying Party desires to defend
the Indemnified Party against the Third Party Claim, then the Indemnifying
Party at its sole cost and expense shall defend, with counsel reasonably
satisfactory to the Indemnified Party, such Third Party Claim by all
appropriate proceedings, which proceedings will be diligently prosecuted to a
final conclusion or will be settled at the discretion of the Indemnifying Party
(with the consent of the Indemnified Party which shall not be unreasonably
withheld).  The Indemnified Party will cooperate in such defense at the sole
cost and expense of the Indemnifying Party.  The Indemnified Party may, at its
sole cost and expense, at any time prior to the Indemnifying Party's delivery
of the notice referred to in the last sentence of the preceding paragraph, file
any pleadings or take any other action that the Indemnified Party reasonably
believes to be necessary or appropriate to protect its interests.  The
Indemnified Party, at its expense, may participate in, but not control, any
defense or settlement of any Third Party Claim conducted by the Indemnifying
Party pursuant to this Section 8.4(a).

         If the Indemnifying Party fails to notify the Indemnified Party within
the Third Party Claim Response Period that the Indemnifying Party desires to
defend the Third Party Claim or if the Indemnifying Party gives such notice but
fails to prosecute diligently or settle the Third Party Claim, then the
Indemnified Party shall defend, at the sole cost and expense of the
Indemnifying Party, the Third Party Claim by all appropriate proceedings, which
proceedings will be prosecuted by the Indemnified Party in a reasonable manner
and in good faith or will be settled at the discretion of the Indemnified Party
(with the consent of the





                                     - 31 -
<PAGE>   43

Indemnifying Party which shall not be unreasonably withheld).  The Indemnifying
Party will, at its sole cost and expense, cooperate in such defense.

         Notwithstanding the foregoing provisions of this Section 8.4(a), if
the Indemnifying Party is determined not to be liable for such Third Party
Claim pursuant to the last paragraph of this Section 8.4(a) and Section 8.4(c),
the Indemnifying Party will not be required to bear the costs and expenses of
the Indemnified Party's defense of the Third Party Claim or the Indemnifying
Party's participation therein pursuant to this Section 8.4(a), and the
Indemnified Party will reimburse the Indemnifying Party in full for all
reasonable costs and expenses incurred by the Indemnifying Party in connection
with such defense.

         If the Indemnifying Party notifies the Indemnified Party that it does
not dispute its liability to the Indemnified Party with respect to the Third
Party Claim under this Article VIII or fails to notify the Indemnified Party
within the Third Party Claim Response Period whether the Indemnifying Party
disputes its liability to the Indemnified Party with respect to such Third
Party Claim, the Losses resulting from such Third Party Claim as finally
determined will be conclusively deemed to be a liability of the Indemnifying
Party under this Article VIII, and the Indemnifying Party shall pay the amount
of such Losses to the Indemnified Party on demand.  If the Indemnifying Party
notifies the Indemnified Party within the Third Party Claim Response Period
that the Indemnifying Party disputes its liability to the Indemnified Party
with respect to such claim, the Indemnifying Party and the Indemnified Party
will proceed in good faith to negotiate a resolution of such dispute, and if
not resolved through negotiations within a period of thirty (30) days from the
date of such notice, such dispute shall be resolved by arbitration in
accordance with Section 8.4(c) hereof.

         (b)     Other Claims.  In the event any Indemnified Party should have
a claim under this Article VIII against any Indemnifying Party that does not
involve a Third Party Claim, the Indemnified Party shall promptly give written
notice and the details thereof, including copies of all relevant information
and documents (collectively, an "Indemnity Notice"), to the Indemnifying Party
within a period of thirty (30) days following the discovery of the claim by the
Indemnified Party (the "Claim Notice Period").  The failure by any Indemnified
Party to give the Indemnity Notice within the Claim Notice Period shall not
impair the Indemnified Party's rights hereunder except to the extent that an
Indemnifying Party demonstrates that it has been prejudiced thereby.  The
Indemnifying Party will notify the Indemnified Party within a period of thirty
(30) days after the receipt of the Indemnify Notice by the Indemnifying Party
(the "Indemnity Response Period") whether the Indemnifying Party disputes its
liability to the Indemnified Party under this Article VIII with respect to such
claim.  If the Indemnifying Party notifies the Indemnified Party that it does
not dispute the claim described in such Indemnity Notice or fails to notify the
Indemnified Party within the Indemnity Response Period whether the Indemnifying
Party disputes the claim described in such Indemnity Notice, the Losses
resulting from such claim as finally determined will be conclusively deemed to
be a liability of the Indemnifying Party under this Article VIII and the
Indemnifying Party shall pay the amount of such Losses to the Indemnified Party
on demand.  If the Indemnifying Party notifies the Indemnified Party within the
Indemnity Response Period that the Indemnifying Party disputes its liability
with respect to such claim, the Indemnifying Party and the Indemnified Party
will proceed in good faith to negotiate a resolution of such dispute, and if
not resolved through negotiations within a period of thirty





                                     - 32 -
<PAGE>   44

(30) days from the date of such notice, such dispute shall be resolved by
arbitration in accordance with Section 8.4(c) hereof.

         (c)     Resolution of Disputes.  Any dispute required to be submitted
to arbitration pursuant to this Section 8.4 shall be finally and conclusively
determined in accordance with the Rules of Arbitration of the International
Chamber of Commerce (the "Rules of Arbitration") then in effect by the decision
of three (3) arbitrators selected in accordance with the Rules of Arbitration
unless the Company and the Purchaser shall agree on a single arbitrator (the
"Board of Arbitration").  The Board of Arbitration shall meet in New York, New
York and shall render a decision in writing (concurred in by a majority of the
members of the Board of Arbitration if more than one) with respect to and
stating the amount, if any, which the Indemnifying Party is required to pay to
the Indemnified Party in respect of the claim made by the Indemnified Party.
To the extent practical, the decision of the Board of Arbitration shall be
rendered no more than thirty (30) days following commencement of proceedings
with respect thereto.  The Board of Arbitration shall cause its written
decision to be delivered to the Indemnified Party and the Indemnifying Party.
Any decision made by the Board of Arbitration (either prior to or after the
expiration of such thirty (30) day period) shall be final, binding and
conclusive on the Indemnified Party and the Indemnifying Party and entitled to
be enforced to the fullest extent permitted by Law and entered in any court of
competent jurisdiction.

         The Company and the Purchaser hereby consent to the jurisdiction of
the foregoing Board of Arbitration and to the jurisdiction of any state or
federal court located in the States of New York or Delaware and any national
court located in France for the purpose of enforcing the decision or award of
the Board of Arbitration.  The Company and the Purchaser agree that service of
process may be made on any such party by personal delivery or by registered or
certified mail addressed to the appropriate party at the address for such party
specified in Section 10.1 hereof.  The submission to the jurisdiction of the
courts referred to above for the purpose of enforcing the decision or award of
the Board of Arbitration shall not (and shall not be construed so as to) limit
the right of either the Company or the Purchaser to file or commence
proceedings against the other in any other court of competent jurisdiction for
the purpose of enforcing the decision or award of the Board of Arbitration nor
shall the filing or commencement of proceedings in any one or more
jurisdictions for such purpose preclude the filing or taking of proceedings in
any other jurisdiction for such purpose (whether concurrently or not) if and to
the extent permitted by applicable Law.

         Each and every arbitration proceeding commenced pursuant to this
Section 8.4(c) shall be consolidated with any arbitration proceeding then
pending under this Section 8.4(c).

         SECTION 8.5  Continued Liability for Indemnity Claims.  The liability
of any Indemnifying Party hereunder with respect to claims hereunder shall
continue for so long as any claims for indemnification may be made hereunder
pursuant to Section 8.8 hereof and, with respect to any such indemnification
claims duly and timely made, thereafter until the Indemnifying Party's
liability therefor is finally determined and satisfied.

<PAGE>   45

         SECTION 8.6  Limitations on Indemnification.

                 (a)      Certain Types of Damages.  Neither the Company nor
         the Purchaser shall be required to provide indemnification hereunder
         for Losses which are indirect or speculative.

                 (b)      Threshold Amount - Claim by Purchaser.  No amount of
         indemnity shall be payable in the case of a claim by the Purchaser
         under Section 8.2(a) unless, until and only to the extent that the
         Purchaser has suffered or incurred Losses aggregating in excess of US
         $100,000 as a result of or arising out of the matters described in
         Section 8.2(a).

                 (c)      Threshold Amount - Claim by Company.  No amount of
         indemnity shall be payable in the case of a claim by the Company under
         Section 8.3(a) unless, until and only to the extent that the Company
         has suffered or incurred Losses aggregating in excess of US $100,000
         as a result of or arising out of the matters described in Section
         8.3(a).

         SECTION 8.7  Exclusive Remedies.  The sole and exclusive remedies for
any party hereto with respect to any claim relating to this Agreement or the
transactions contemplated hereby and the facts and circumstances relating and
pertaining hereto shall be governed by this Agreement (whether any such claim
shall be made in contract, breach of warranty, tort or otherwise).

         SECTION 8.8  Time Limits on Claims.  A claim by any Indemnified Party
under this Article VIII may be made only:

                 (a)      if with respect to the violation of a representation
         or warranty, within two (2) years following the Closing Date, with the
         exception of Sections 3.3, 3.8, 3.15 and 3.17 with respect to which
         such representations and warranties shall survive, and claims thereon
         may be made, until four (4) years following the Closing Date; and

                 (b)      if with respect to the violation of a covenant or
         agreement, or pursuant to Section 8.2(c), until the expiration of the
         applicable statute of limitations relating thereto.

         Notwithstanding anything in this Agreement to the contrary, any claim
not made within the foregoing relevant time period shall expire and be forever
barred thereafter.

                                  TERMINATION

                         REGISTRATION RIGHTS AGREEMENT


         THIS REGISTRATION RIGHTS AGREEMENT (the " Agreement") is entered into
as of the 6th day of September, 1996 by and between SSE TELECOM, INC., a
Delaware corporation (the "Company"), and ALCATEL TELSPACE, a societe anonyme
organized under the laws of France (the "Purchaser").


                              W I T N E S S E T H:

         WHEREAS, simultaneously with the execution of this Agreement, (i) the
Purchaser will purchase 525,000 shares of the common stock of the Company from
the Company pursuant to the terms of that certain Stock Purchase and Investment
Agreement dated as of September 6, 1996 (the "Investment Agreement"), and (ii)
the Purchaser will purchase 100,000 shares of the common stock of the Company
from certain stockholders of the Company pursuant to the terms of that certain
Stock Purchase Agreement dated as of September 6, 1996 (the "Selling
Stockholder Agreement"); and

         WHEREAS, the execution of this Agreement by the parties hereto is a
condition precedent to the obligation of the Purchaser to consummate the
transactions contemplated by the Investment Agreement and the Selling
Stockholder Agreement.

         NOW, THEREFORE, in consideration of the mutual promises, covenants,
representations and warranties contained herein and of the mutual benefits to
be derived herefrom, and intending to be legally bound, the parties hereto
agree as follows:

         SECTION 1.          Demand Registrations.

                 (a)         Requests for Registration.  At any time during the
         Registration Period, the holders of at least fifty percent (50%) of
         the Registrable Securities may request the Company to effect a
         registration under the Securities Act of all or part of their
         Registrable Securities.  Each request for a Demand Registration shall
         specify the number of Registrable Securities requested to be
         registered.  Within ten (10) days after receipt of any such request,
         the Company will give written notice of such requested registration to
         all other holders of Registrable Securities and will include in such
         registration, subject to Section 1(c) hereof, all Registrable
         Securities with respect to which the Company has received written
         requests for inclusion therein within thirty (30) days after the
         receipt of the Company's notice.

                 (b)         Number of Demand Registrations.  The holders of
         Registrable Securities, as a group and not individually, will be
         entitled to require only one Demand Registration pursuant to this
         Section 1, provided, however , that in the event all of the holders of
         the Registrable Securities irrevocably decide to sell all of the
         Registrable Securities then owned by such holders as soon as is
         practical and so notify the Company in writing, then the limitation
         otherwise imposed by this Section 1(b) shall not apply (whether or not
         a registration has been previously made pursuant to
<PAGE>   51

         Section 1(a)) and such holders shall be entitled to, and do hereby
         irrevocably agree that they will in fact continue to, exercise their
         rights set forth in Section 1(a), promptly and to the maximum extent
         permitted by the managing underwriter with respect to any particular
         registration, until such time as such holders have disposed of all the
         Registrable Securities owned by them.  A registration will not be
         considered to be a Demand Registration unless and until:

                               (i)         it has remained effective for three
                 hundred sixty-five (365) consecutive days or such shorter
                 period as shall be required to sell all of the securities
                 registered pursuant thereto (but not terminating before the
                 expiration of the applicable prospectus delivery period); and

                              (ii)         all Registrable Securities requested
                 to be included therein are effectively included therein and
                 saleable thereunder.

                 (c)         Priority on Registration.  The Company may include
         in any Demand Registration any securities which are not Registrable
         Securities but which are of the same class as the Registrable
         Securities and which are held by holders who have piggyback
         registration rights with respect to the demand registration rights
         provided under this Agreement.  If a Demand Registration is an
         underwritten offering and the managing underwriters advise the Company
         in writing that in their opinion the number of Registrable Securities
         and, if permitted hereunder, other securities requested to be included
         in such offering exceeds the number of Registrable Securities and
         other securities, if any, which can be sold in an orderly manner in
         such offering within a price range acceptable to the holders of a
         majority of the Registrable Securities, then the Company will include
         in such registration, prior to the inclusion of any securities which
         are not Registrable Securities, the number of Registrable Securities
         requested to be included pro rata among the respective holders thereof
         on the basis of the amount of Registrable Securities requested by such
         holders to be included in such registration, so that no securities
         other than Registrable Securities will be included in such
         registration if the inclusion of such securities would result in a
         limitation on the number of Registrable Securities to be included
         therein.

                 (d)         Restrictions on Demand Registration.  The Company
         may postpone for up to three (3) months the filing or the
         effectiveness of a registration statement for a Demand Registration if
         (i) the Company, in the good faith judgment of its Board of Directors,
         determines that such Demand Registration would reasonably be expected
         to have an adverse effect on any proposal or plan by the Company or
         any of its Subsidiaries to engage in any acquisition (other than in
         the ordinary course of business) or any merger, recapitalization,
         consolidation, reorganization, tender offer or similar transaction or
         negotiations, discussions or pending proposals with respect thereto or
         would require the Company to make premature public disclosure of
         information, the premature disclosure of which would have a material
         adverse effect on the business or prospects of the Company, or would
         otherwise be seriously detrimental to the Company or its stockholders,
         and (ii) the Company provides the holders of the Registrable
         Securities with a written certificate signed by the president of the
         Company stating the reasons of the Board of Directors for such delay,





                                     - 2 -
<PAGE>   52

         provided, however, that the Company may not utilize this right more
         than once in any twelve (12) month period, and provided further, that,
         in such event, the holders of Registrable Securities initially
         requesting such Demand Registration will be entitled to withdraw such
         request and, if such request is withdrawn, such Demand Registration
         will not be considered to be a Demand Registration hereunder, and the
         Company will pay all Registration Expenses in connection with such
         registration.

                 (e)         Selection of Underwriters.  If any Demand
         Registration is in the form of an underwritten offering, the Company
         will select and retain the investment banker or investment bankers and
         manager or managers that administer the offering; provided, however,
         that such selection will be subject to the approval of the holders of
         a majority of the Registrable Securities participating in such
         registration, which shall not be unreasonably withheld.  The Company
         shall (together with all holders proposing to distribute their
         securities through such underwriting) enter into and perform its
         (their) obligations under an underwriting agreement in customary form
         with the managing underwriter selected for such underwriting.  If any
         holder of Registrable Securities disapproves of the terms of the
         underwriting, such holder may elect to withdraw therefrom by written
         notice to the Company and the managing underwriter.  The Registrable
         Securities so withdrawn shall also be withdrawn from registration.

         SECTION 2.          Piggyback Registrations.

                 (a)         Right to Piggyback.  Whenever the Company proposes
         to register any of its securities under the Securities Act (including
         securities registered for selling stockholders with demand registration
         rights, subject to the limitations set forth in Section 2(d) below) and
         the registration form to be used may be used for the registration of
         Registrable Securities, the Company will give prompt written notice to
         all holders of Registrable Securities, and to the holders of any other
         securities of the Company having registration rights compatible with
         the proposed registration form, of its intention to effect such a
         registration and will include in such registration all Registrable
         Securities with respect to which the Company has received written
         requests for inclusion therein within fifteen (15) days after the
         receipt of the Company's notice (a "Piggyback Registration ").  If the
         Company gives notice of such a proposed registration, the total number
         of Registrable Securities which shall be included in such registration
         shall be limited to such number, if any, as in the reasonable opinion
         of the manager of such offering would not adversely affect the
         marketability or offering price of all of the securities proposed to be
         offered by the Company in such offering; provided, however, if the
         holders of Registrable Securities having registration rights upon a
         Piggyback Registration are not permitted to include all of such
         Registrable Securities by reason of such determination by the manager
         of the offering, the Registrable Securities to be included in the
         offering shall be determined in accordance with Sections 2(c) and 2(d)
         below.  Notwithstanding the foregoing, the Company may, in its sole
         discretion and without the consent of any holder of Registrable
         Securities, withdraw such registration statement and abandon such
         proposed public offering.





                                     - 3 -
<PAGE>   53

                 (b)         Piggyback Expenses.  The Registration Expenses of
         the holders of the Registrable Securities will be paid by the Company
         in all Piggyback Registrations, including proposed Piggyback
         Registrations which are abandoned.

                 (c)         Priority on Primary Registrations.  If a Piggyback
         Registration is a primary registration initiated by or on behalf of
         the Company and the managing underwriters advise the Company in
         writing that in their opinion the number of securities requested to be
         included in such registration exceeds the number which can be sold in
         an orderly manner in such offering within a price range acceptable to
         the Company, then the Company will include in such registration (i)
         first, the securities the Company proposes to sell, and (ii) second,
         securities of the holders requesting such registration, pro rata among
         the holders requesting inclusion in the registration on the basis of
         the number of such securities requested to be included in such
         registration by each such holder.

                 (d)         Priority on Secondary Registrations.  If a
         Piggyback Registration is an underwritten secondary registration
         initiated by or on behalf of holders of the Company's securities
         exercising demand registration rights and the managing underwriters
         advise the Company in writing that in their opinion the number of
         securities requested to be included in such registration exceeds the
         number which can be sold in an orderly manner in such offering within
         a price range acceptable to the holders initially requesting such
         registration, then the Company will include in such registration (i)
         first, the securities requested to be included therein by the holders
         exercising demand registration rights, and (ii) second, the
         Registrable Securities and other securities requested to be included
         in such registration by Persons holding piggyback registration rights,
         pro rata among the holders of such securities on the basis of the
         number of such securities requested to be included in such
         registration by each such holder.

         SECTION 3.          Form S-3 Registrations.

                 (a)         Requests for Registration.  At any time during the
         Registration Period, a holder of Registrable Securities may request
         that the Company effect a registration on Form S-3 and any related
         qualification or compliance under the Securities Act with respect to
         all or part of its Registrable Securities.  Each request for a Form
         S-3 Registration shall specify the appropriate number of Registrable
         Securities requested to be registered.  Within ten (10) days after
         receipt of any such request, the Company will give written notice of
         such requested registration to all other holders of Registrable
         Securities and will include in such registration, subject to Section
         3(c), all Registrable Securities with respect to which the Company has
         received written requests for inclusion therein within thirty (30)
         days after the receipt of the Company's notice.

                 (b)         Restrictions on Form S-3 Registrations.  Each
         holder of Registrable Securities will be entitled to require unlimited
         Form S-3 Registrations pursuant to this Section 3, provided, however,
         that the Company shall not be obligated to effect any such
         registration, qualification or compliance pursuant to this Section 3
         if (i) Form S-





                                     - 4 -

         3 is not available for such offering by the holders of Registrable
         Securities, (ii) such holders, together with the holders of any other
         securities of the Company entitled to inclusion in such registration,
         propose to sell Registrable Securities and such other securities (if
         any) aggregating less than 100,000 shares or at an aggregate price to
         the public of less than $1,000,000, provided that this clause (ii)
         shall not apply with respect to the exercise by the holders of
         Registrable Securities of their rights under Section 1 hereof
         following the giving of the notice permitted by Section 1(b) hereof,
         (iii) the Company shall furnish to the holders a written certificate
         signed by the president of the Company stating that, in the good faith
         judgment of the Board of Directors of the Company, it would reasonably
         be expected to have an adverse effect on any proposal or plan by the
         Company or any of its Subsidiaries to engage in any acquisition (other
         than in the ordinary course of business) or any merger,
         recapitalization, consolidation, reorganization, tender offer or
         similar transaction or negotiations, discussions or pending proposals
         with respect thereto or would require the Company to make premature
         public disclosure of information, the premature disclosure of which
         would have a material adverse effect on the business or prospects of
         the Company, or would otherwise be seriously detrimental to the
         Company or its stockholders, for such Form S-3 registration to be
         effected at such time, in which event the Company shall have the right
         to defer the filing of the Form S-3 registration statement for a
         period of not more than ninety (90) days after receipt of the request
         of the holder under this Section 3, provided, however, that the
         Company shall not utilize this right more than once in any twelve
         month (12) period, provided further, that, in such event, the holders
         of Registrable Securities initially requesting such Form S-3
         Registration will be entitled to withdraw such request, (iv) the
         Company has, within the twelve (12) month period preceding the date of
         such request, already effected two registrations on Form S-3 for the
         holders of Registrable Securities pursuant to this Section 3,
         provided, however, that this clause (iv) shall not apply with respect
         to the exercise by the holders of Registrable Securities of their
         rights under Section 1 hereof following the giving of the notice
         permitted by Section 1(b) hereof, or (v) in effecting such
         registration, qualification or compliance, the Company would be
         required to qualify to do business or to execute a general consent to
         service of process in any jurisdiction in which the Company was not
         already so qualified or had not already executed such consent.  Any
         Form S-3 Registration effected pursuant to this Section 3 shall not be
         considered to be a Demand Registration pursuant to Section 1 of this
         Agreement.

                 (c)         Priority on Registration.  The Company may include
         in any Form S-3 Registration any securities which are not Registrable
         Securities but which are of the same class as the Registrable
         Securities and which are held by holders who have piggyback
         registration rights with respect to the Form S-3 registration rights
         provided under this Agreement.  If a Form S-3 Registration is an
         underwritten offering and the managing underwriters advise the Company
         in writing that in their opinion the number of Registrable Securities
         and, if permitted hereunder, other securities requested to be included
         in such offering exceeds the number of Registrable Securities and
         other securities, if any, which can be sold in an orderly manner in
         such offering within a price range acceptable to the holders of a
         majority of the Registrable Securities, then the Company will include
         in such registration, prior to the inclusion





                                     - 5 -
<PAGE>   55

         of any securities which are not Registrable Securities, the number of
         Registrable Securities requested to be included pro rata among the
         respective holders thereof on the basis of the amount of Registrable
         Securities requested by such holders to be included in such
         registration, so that no securities other than Registrable Securities
         will be included in such registration if the inclusion of such
         securities would result in a limitation on the number of Registrable
         Securities to be included therein.

                 (d)         Undertakings by the Company.  In addition to any
         other obligations of the Company set forth herein with respect to the
         use of a Form S-3 Registration by the holders of Registrable
         Securities to sell securities of the Company to the public, the
         Company shall:

                               (i)         take such action as is necessary and
                 may reasonably be accomplished by the Company to enable the
                 holders of Registrable Securities to utilize Form S-3 for the
                 sale of their Registrable Securities, including, but not
                 limited to, the filing with the SEC in a timely manner all
                 reports and other documents required of the Company under the
                 Securities Act and the Exchange Act; and

                              (ii)         furnish to any holder, so long as
                 such holder owns any Registrable Securities, forthwith upon
                 request (i) a written statement by the Company that it
                 qualifies as a registrant whose securities may be resold
                 pursuant to Form S-3, (ii) a copy of the most recent annual or
                 quarterly report of the Company and such other reports and
                 documents so filed by the Company, and (iii) such other
                 information as may be reasonably requested in availing such
                 holder of any rule or regulation of the SEC that permits the
                 selling of any such securities pursuant to Form S-3 or similar
                 form.

                 (e)         Selection of Underwriters.  If any Form S-3
         Registration is in the form of an underwritten offering, the Company
         will select and retain the investment banker or investment bankers and
         manager or managers that administer the offering, provided, however,
         that such selection will be subject to the approval of the holders of
         a majority of the Registrable Securities participating in such
         registration, which shall not be unreasonably withheld.  The Company
         shall (together with all holders proposing to distribute their
         securities through such underwriting) enter into and perform its (and
         their) obligations under an underwriting agreement in customary form
         with the managing underwriter selected for such underwriting.  If any
         holder of Registrable Securities disapproves of the terms of the
         underwriting, such holder may elect to withdraw therefrom by written
         notice to the Company and the managing underwriter.  The Registrable
         Securities so withdrawn shall also be withdrawn from registration.

         SECTION 4. Resales Pursuant to Rule 144.  In order to make available
to the holders of Registrable Securities the benefits of Rule 144 and any other
rule or regulation of the SEC that may at any time permit a holder of
Registrable Securities to sell securities of the Company to the public without
registration, the Company shall:





                                     - 6 -
<PAGE>   56

                 (a)         make and keep adequate current public information
available at all times as required by Rule 144; and

                 (b)         take such action as is necessary to enable the
holders of Registrable Securities to utilize Rule 144 for the sale of their
Registrable Securities, including, but not limited to, the filing with the SEC
in a timely manner all reports and other documents required of the Company
under the Exchange Act; and

                 (c)         furnish to any holder, so long as such holder owns
any Registrable Securities, forthwith upon request (i) a written statement by
the Company that it has complied with the reporting requirements of Rule 144,
the Securities Act and the Exchange Act, (ii) a copy of the most recent annual
or quarterly report of the Company and such other reports and documents so
filed by the Company, and (iii) such other information as may be reasonably
requested by such holder to permit the holder to use any rule or regulation of
the SEC that permits the selling of any such securities without registration.

         SECTION 5.          Holdback Agreements

                 (a)         By Holders.  Each holder of Registrable Securities
         agrees not to effect any pubic sale or distribution (including sales
         pursuant to Rule 144) of any Registrable Securities, within seven (7)
         days prior to, and during the 120-day period beginning on, the date
         specified in writing by the Company to such holder as the effective
         date of any underwritten Demand Registration or any underwritten
         Piggyback Registration in which Registrable Securities of such holder
         are included (except as part of such underwritten registration),
         unless the underwriters managing the registered public offering
         otherwise agree, provided that officers and directors of the Company
         enter into similar agreements.

                 (b)         By the Company.  The Company agrees not to effect
         any public sale or distribution of its equity securities, or any
         securities convertible into or exchangeable or exercisable for such
         securities, within seven (7) days prior to, and during the 120-day
         period beginning on, the effective date of any underwritten Demand
         Registration or any underwritten Piggyback Registration (except as
         part of such underwritten registration or pursuant to registrations on
         Form S-4 or Form S-8 or any successor form), unless the underwriters
         managing the registered public offering otherwise agree.

         SECTION 6.          Registration Procedures.  Whenever the holders of
Registrable Securities have requested that any Registrable Securities be
registered pursuant to Sections 1, 2 or 3 of this Agreement, the Company will
use its best efforts to effect the registration and the sale of such
Registrable Securities in accordance with the intended method of disposition
thereof, and pursuant thereto the Company will as expeditiously as possible:

                 (a)         Prepare and file with the SEC a registration
statement on the appropriate form with respect to such Registrable Securities
and use its best efforts to cause such registration statement to become
effective within ninety (90) days of the date that the Company received a
request for the registration of such Registrable Securities from the





                                     - 7 -
<PAGE>   57

holders in accordance with the terms of Sections 1(a), 2(a) or 3(a) above, as
the case may be; and

                 (b)         Prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in
connection therewith as may be necessary to keep such registration statement
effective for a period of not less than one hundred twenty (120) consecutive
days (three hundred sixty-five (365) consecutive days with respect to a Demand
Registration under Section 1 hereof) or such shorter period which will
terminate when Registrable Securities covered by such registration statement
have been sold (but not before the expiration of the applicable prospectus
delivery period) and comply with the provisions of the Securities Act with
respect to the disposition of all securities covered by such registration
statement during such period in accordance with the intended methods of
disposition by the sellers thereof set forth in such registration statement;
and

                 (c)         Furnish to each seller of Registrable Securities
such number of copies of such registration statement, each amendment and
supplement thereto, the prospectus included in such registration statement
(including each preliminary prospectus) and such other documents as such seller
may reasonably request in order to facilitate the disposition of the
Registrable Securities owned by such seller; and

                 (d)         Use its best efforts to register or qualify such
Registrable Securities under such other securities or blue sky laws of such
jurisdictions within the United States as the sellers shall request and do any
and all other acts and things which may be reasonably necessary or advisable to
enable such sellers to consummate the disposition in such jurisdictions of the
Registrable Securities owned by such sellers (provided that the Company will
not be required to qualify generally to do business or file any general consent
to service of process in any jurisdiction where it would not otherwise be
required to qualify or file but for this subparagraph); and

                 (e)         Notify each seller of such Registrable Securities
at any time when a prospectus relating thereto is required to be delivered
under the Securities Act of the happening of any event as a result of which the
prospectus included in such registration statement contains an untrue statement
of a material fact or omits to state any material fact required to be stated
therein or necessary to make the statements therein not misleading in light of
the circumstances then existing, and at the request of any such seller, the
Company will prepare and file promptly with the SEC, and promptly notify each
holder of Registrable Securities of the filing of, a supplement or amendment to
such prospectus so that, as thereafter delivered to the purchasers of such
Registrable Securities, such prospectus will not contain an untrue statement of
a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein not misleading in light of
the circumstances under which they were made; and

                 (f)         Make available for inspection by any seller of
Registrable Securities, any underwriter participating in any disposition
pursuant to such registration statement and any attorney, accountant or other
agent retained by any such seller or underwriter, all financial and other
records (reasonably requested), pertinent corporate documents and contracts of
the Company as shall be reasonably necessary to enable them to exercise their





                                     - 8 -
<PAGE>   58

due diligence responsibility, and cause the Company's officers, directors,
employees and independent accountants to supply all information reasonably
requested by any such seller, underwriter, attorney, accountant or agent in
connection with such registration statement, provided, however, that each
seller of Registrable Securities agrees that information obtained by it as a
result of such inspections which is deemed confidential shall not be used by it
as the basis for any market transaction in securities of the Company unless and
until such information is made generally available to the public and each such
seller shall cause any attorney, accountant or agent retained by such seller to
keep confidential any such information; and

                 (g)         In the event of the issuance of any stop order
suspending the effectiveness of a registration statement, or of any order
suspending or preventing the use of any related prospectus or suspending the
qualification of any common stock included in such registration statement for
sale in any jurisdiction, the Company will use reasonable efforts promptly to
obtain the withdrawal of such order; and

                 (h)         If the offering is to be underwritten, enter into
any necessary agreements in connection therewith (including an underwriting
agreement containing customary representations, warranties and agreements); and

                 (i)         Take all such other reasonable actions in
connection therewith in order to expedite or facilitate the disposition of such
Registrable Securities and in such connection, whether or not an underwriting
agreement is entered into and whether or not the registration is an
underwritten registration, make such representations and warranties to the
holders of such Registrable Securities and the underwriters, if any, in such
form, substance and scope as are customarily made by issuers to underwriters in
primary underwritten offerings, obtain opinions of counsel to the Company and
updates thereof (which counsel and opinions, in form, scope and substance,
shall be reasonably satisfactory to the managing underwriters, if any, and the
sellers), and obtain "cold comfort" letters and updates thereof from the
Company's independent certified public accountants addressed to the sellers and
the underwriters, if any, such letters to be in customary form and covering
matters of the type customarily covered in "cold comfort" letters to
underwriters in connection with primary underwritten offerings.

         SECTION 7.          Registration Expenses.

                 (a)         Company Expenses.  All expenses (herein called
         "Registration Expenses") incident to the Company's performance of or
         compliance with this Agreement, including, without limitation, all
         registration and filing fees, fees and expenses of compliance with
         securities and blue sky laws, printing expenses, messenger and
         delivery expenses, fees and disbursements of counsel for the Company,
         and fees and disbursements of all the Company's certified public
         accountants, underwriters (excluding discounts and commissions) and
         any Persons retained by the Company, will be paid by the Company.

                 (b)         Holder Expenses.  Except as otherwise paid by the
         Company pursuant to Section 7(a) above, each holder of Registrable
         Securities shall bear all





                                     - 9 -
<PAGE>   59

         expenses incurred by such holder in connection with the negotiation
         and preparation of any registration statement, underwriting agreement
         and all other documents and instruments contemplated hereby to which
         any such holder is a party, including, without limitation, the fees
         and expenses, if any, of its legal counsel, provided, however, that if
         such holder learns of a material adverse change in the condition,
         business, or prospects of the Company after such holder has decided to
         participate, and has notified the Company of its decision to
         participate, in a registration pursuant to the terms of this
         Agreement, then such holder shall be free to withdraw from such
         registration and the Company shall pay all expenses, including, but
         not limited to, expenses incurred by such holder in connection with
         such registration, provided further, however, that if such holder
         initiated a Demand Registration but such registration is not
         considered to be a Demand Registration in accordance with the terms of
         Section 1(b) hereof, then the Company shall pay all expenses,
         including, but not limited to, expenses incurred by such holder, in
         connection with such registration.

         SECTION 8.          Undertakings of the Holders of Registrable
Securities.

                 (a)         Suspension of Sales.  If any Registrable Securities
         are included in a registration statement pursuant to the terms of this
         Agreement, the holder thereof will not (until further notice) effect
         sales thereof after receipt of written notice from the Company to
         suspend sales to permit the Company to correct or update a registration
         statement or prospectus, provided that the obligations of the Company
         with respect to maintaining any registration statement current and
         effective shall be extended by a period of days equal to the period
         said suspension is in effect.

                 (b)         Compliance.  If any Registrable Securities are
         being registered in any registration pursuant to this Agreement, the
         holder thereof will comply with all anti-stabilization, manipulation
         and similar provisions of Section 10 of the Exchange Act, and any
         rules promulgated thereunder by the SEC and, at the request of the
         Company, will execute and deliver to the Company and to any
         underwriter participating in such offering an appropriate agreement to
         such effect.

                 (c)         Termination of Effectiveness.  At the end of the
         period during which the Company is obligated to keep a registration
         statement current and effective as described herein, each holder of
         Registrable Securities included in the registration statement shall
         discontinue sales thereof pursuant to such registration statement,
         unless such holder has received written notice from the Company of its
         intention to continue the effectiveness of such registration statement
         with respect to any of such securities which remain unsold.

         SECTION 9.          Underwritten Registrations.

                 (a)         Furnish Information.  No holder of Registrable
         Securities may participate in any registration hereunder which is
         underwritten unless such holder (i) agrees to sell such holder's
         securities on the basis provided in any underwriting arrangements
         approved by the holder or holders entitled hereunder to approve such
         arrangements, and (ii) completes and executes all customary
         questionnaires, powers of





                                     - 10 -
<PAGE>   60

         attorney, indemnities, underwriting agreements and other documents
         reasonably required under the terms of such underwriting arrangements,
         provided that no holder of Registrable Securities included in any
         underwritten registration shall be required to make any
         representations or warranties to the Company or the underwriters on
         account of the registration of shares owned by such holder other than
         representations and warranties regarding such holder and such holder's
         intended method of distribution.

                 (b)         Right of Approval.  The Company shall not include
         in any registration statement (or attachments or exhibits thereto)
         filed by the Company (under this Agreement or otherwise) pursuant to
         the Securities Act any information describing or relating to the
         Purchaser or any Purchaser Affiliate or the relationship of the
         Purchaser or any Purchaser Affiliate with the Company without the
         advance written consent of the Purchaser, which consent shall not be
         unreasonably withheld or delayed.

                 (c)         Delay of Registration.  No holder of Registrable
         Securities shall have any right to obtain or seek an injunction
         restraining or otherwise delaying the preparation of, or declaration
         of the effectiveness of, any registration statement initiated in
         accordance with the terms of this Agreement if such injunction is the
         result of any controversy that might arise with respect to the
         interpretation or implementation of this Agreement.

         SECTION 10.         Assignment of the Purchaser's Registration Rights.
The rights of a holder of Registrable Securities set forth in this Agreement,
including the right to cause the Company to register Registrable Securities and
pay the Registration Expenses, to the extent set forth herein, incurred in
connection therewith, may be assigned by such holder to a Purchaser Affiliate
which acquires Registrable Securities.  All Registrable Securities held or
acquired by a Purchaser Affiliate shall be aggregated with all Registrable
Securities held by the Purchaser for the purpose of determining the
availability to the holders of Registrable Securities of any rights under this
Agreement.  For purposes of this Agreement, the term "Purchaser Affiliate"
means any Person that, directly or indirectly, controls or is controlled by or
is under common control with the Purchaser.  For purposes of this definition,
control of a Person means the power, directly or indirectly, to direct or cause
the direction of the management and policies of such Person, whether by
contract or otherwise and, in any event and without limiting the foregoing, any
Person owing fifty percent (50%) or more of the voting securities of another
Person shall be deemed to control that Person.

         SECTION 11.         Other Registration Rights.  The Purchaser
acknowledges that it has received copies of (a) that certain Registration
Agreement, dated January 28, 1996 (the "Fairchild Agreement"), by and between
the Company and Fairchild Data Corporation; (b) that certain agreement, dated
as of March 14, 1994 (the "EchoStar Agreement"), by and between the Company and
EchoStar Communications Corporation ("EchoStar"), pursuant to which the Company
granted certain registration rights to EchoStar; and (c) that certain letter
agreement, dated August 2, 1996 (the "EchoStar Letter"), from the Company to
EchoStar, pursuant to which the Company agreed to grant certain additional
registration rights to EchoStar at least as favorable to EchoStar as those set
forth in the Fairchild Agreement in





                                     - 11 -
<PAGE>   61

the event the Company issues shares of Common Stock to EchoStar in connection
with the exercise of certain warrants that may be issued by the Company after
the date hereof.  To the extent the registration rights provided for in the
EchoStar Letter are set forth in a written document after the date hereof, such
document shall be referred to herein as the "New Registration Agreement."  The
Fairchild Agreement, the EchoStar Agreement, the EchoStar Letter and the New
Registration Agreement shall collectively be referred to herein as the "Company
Registration Documents").

         In the event that (i) a Demand Registration or a Form S-3
Registration, as the case may be, is requested and the provisions of Section
1(c) or Section 3(c) hereof, as the case may be, cannot be implemented by the
Company without conflicting with its obligations under Section 2(d) of the
Fairchild Agreement, Section 8(c) of the EchoStar Agreement, or the provision
contained in the New Registration Agreement that is substantially similar to
Section 2(d) of the Fairchild Agreement; (ii) a Piggyback Registration is
requested and the provisions of Section 2(c) hereof cannot be implemented by
the Company without conflicting with its obligations under Section 8(b) of the
EchoStar Agreement; or (iii) a Piggyback Registration is requested and the
provisions of Section 2(d) hereof cannot be implemented by the Company without
conflicting with its obligations under Section 8(c) of the EchoStar Agreement,
then the Company shall use its best efforts to (x) with respect to subparagraph
(i) of this Section 11, convince all holders of securities of the Company,
whose registration rights are in conflict with Section 1(c) or Section 3(c)
hereof, as the case may be, requesting inclusion in such Demand Registration or
Form S-3 Registration, as the case may be, to execute a waiver of such rights
so that such Demand Registration or Form S-3 Registration, as the case may be,
can be completed in a manner which complies with Section 1(c) or Section 3(c)
hereof, as the case may be; (y) with respect to subparagraph (ii) of this
Section 11, convince all holders of securities of the Company, whose
registration rights are in conflict with Section 2(c) hereof, requesting
inclusion in such Piggyback Registration to execute a waiver of such rights so
that such Piggyback Registration can be completed in a manner which complies
with Section 2(c) hereof; and (z) with respect to subparagraph (iii) of this
Section 11, convince all holders of securities of the Company, whose
registration rights are in conflict with Section 2(d) hereof, requesting
inclusion in such Piggyback Registration to execute a waiver of such rights so
that such Piggyback Registration can be completed in a manner which complies
with Section 2(d) hereof.  If, despite the use of its best efforts, the Company
is unable to obtain any waiver described above, then the holders of the
Registrable Securities requesting such Demand Registration or Piggyback
Registration, as the case may be, shall cooperate with the Company to resolve
any conflict described above in the Company Registration Documents.

         Other than the New Registration Agreement, from and after the date of
this Agreement, the Company shall not, without the prior written consent of the
holders of a majority of the Registrable Securities, enter into any agreement
with any holder or prospective holder of any securities of the Company that
would allow such holder or prospective holder to make a demand registration
that would adversely affect the rights of any holder of Registrable Securities
hereunder.

         SECTION 12.         Indemnification.

                 (a)         Indemnification by the Company.  The Company shall
         indemnify and hold harmless, with respect to any registration
         statement filed by it, to the fullest extent permitted by law, each
         holder of Registrable Securities covered by such registration
         statement, its officers, directors, employees, agents and general or
         limited partners (and the directors, officers, employees and agents
         thereof) and each other Person, if any, who controls such holder
         within the meaning of the Securities Act (collectively, the " Holder
         Indemnified Parties") against all losses, claims, damages, liabilities
         and expenses joint or several (including reasonable fees of counsel
         and any amounts paid in settlement effected with the Company's
         consent, which consent shall not be unreasonably delayed or withheld)
         to which any such Holder Indemnified Party may become subject under
         the Securities Act, the Exchange Act, any other federal law, any state
         or common law, any rule or regulation promulgated thereunder or
         otherwise, insofar as such losses, claims, damages liabilities or
         expenses (or actions or proceedings, whether commenced or threatened,
         in respect thereof) are caused by (i) any untrue statement or alleged
         untrue statement of a material fact contained in any registration
         statement in which such Registrable Securities were included as
         contemplated hereby or the omission or alleged omission to state
         therein a material fact required to be stated therein or necessary to
         make the statements therein not misleading, (ii) any untrue statement
         or alleged untrue statement of a material fact contained in any
         preliminary, final or summary prospectus, together with the documents
         incorporated by reference therein (as amended or supplemented if the
         Company shall have filed with the SEC any amendment thereof or
         supplement thereto), or the omission or alleged omission to state
         therein a material fact required to be stated therein or necessary in
         order to make the statements therein, in the light of the
         circumstances under which they were made, not misleading, or (iii) any
         violation by the Company of the Securities Act, the Exchange Act, any
         other federal law, any state or common law, or any rule or regulation
         promulgated thereunder in connection with any such registration; and
         in each such case, the Company shall reimburse each such Holder
         Indemnified Party for any reasonable legal or any other expenses
         incurred by any of them in connection with investigating or defending
         any such loss, claim, damage, liability, expense, action or
         proceeding, provided, however, that the Company shall not be liable to
         any such Holder Indemnified Party in any such case to the extent that
         any such loss, claim, damage, liability or expense (or action or
         proceeding, whether commenced or threatened, in respect thereof)
         arises out of or is based upon any untrue statement or alleged untrue
         statement or omission or alleged omission made in such registration
         statement or amendment thereof or supplement thereto or in any such
         preliminary, final or summary prospectus in reliance upon and in
         strict conformity with written information furnished to the Company by
         or on behalf of any such Holder Indemnified Party relating to such
         Holder Indemnified Party for use in the preparation thereof, and
         provided further, that the Company shall not be liable to any such
         Holder Indemnified Party with respect to any preliminary prospectus to
         the extent that any such loss, claim, damage, liability or expense of
         such Holder Indemnified Party results from the fact that such Holder
         Indemnified Party sold Registrable Securities to a Person to whom
         there was not sent or given, at or before the written confirmation of
         such sale, a copy of the prospectus





                                     - 13 -
<PAGE>   63

         (excluding documents incorporated by reference) or of the prospectus
         as then amended or supplemented (excluding documents incorporated by
         reference) if the Company has previously furnished copies thereof to
         such Holder Indemnified Party in compliance with this Agreement and
         the loss, claim, damage, liability or expense of such Holder
         Indemnified Party results from an untrue statement or omission of a
         material fact contained in such preliminary prospectus which was
         corrected in the prospectus (or the prospectus as amended or
         supplemented).  Such indemnity and reimbursement of expenses and
         obligations shall remain in full force and effect regardless of any
         investigation made by or on behalf of the Holder Indemnified Parties
         and shall survive the transfer of such securities by such Holder
         Indemnified Parties.

                 (b)         Indemnification by Holders.  Each holder of
         Registrable Securities participating in any registration hereunder
         shall indemnify and hold harmless, to the fullest extent permitted by
         law, the Company, its directors, officers, employees and agents, and
         each Person who controls the Company (within the meaning of the
         Securities Act) (collectively, " Company Indemnified Parties") against
         all losses, claims, damages, liabilities and expenses, joint or several
         (including reasonable fees of counsel and any amounts paid in
         settlement effected with such holder's consent, which consent shall not
         be unreasonably delayed or withheld) to which any Company Indemnified
         Parties may become subject under the Securities Act, the Exchange Act,
         any other federal law, any state or common law or otherwise, insofar as
         such losses, claims, damages, liabilities or expenses (or actions or
         proceedings, whether commenced or threatened, in respect thereof) are
         caused by (i) any untrue statement or alleged untrue statement of a
         material fact contained in any registration statement in which such
         holder's Registrable Securities were included or the omission or
         alleged omission to state therein a material fact required to be stated
         therein or necessary to make the statements therein not misleading,
         (ii) any untrue statement or alleged untrue statement of a material
         fact contained in any preliminary, final or summary prospectus,
         together with the documents incorporated by reference therein (as
         amended or supplemented if the Company shall have filed with the
         Commission any amendment thereof or supplement thereto), or the
         omission or alleged omission to state therein a material fact required
         to be stated therein or necessary in order to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading, and in the cases described in clauses (i) and (ii) of
         this Section 12(b), to the extent, but only to the extent, that such
         untrue statement or omission is contained in any information furnished
         in writing by such holder relating to such holder for use in the
         preparation of the documents described in such clauses (i) and (ii) and
         the Company does not know, at the time such information is included in
         the registration statement, prospectus, preliminary prospectus,
         amendment or supplement, that such information is false or misleading,
         (iii) any violation by such holder of the Securities Act, the Exchange
         Act, any other federal law, any state or common law, or any rule or
         regulation promulgated thereunder applicable to such holder and
         relating to action of or inaction by such holder in connection with any
         such registration, and (iv) with respect to any preliminary prospectus,
         the fact that such holder sold Registrable Securities to a Person to
         whom there was not sent or given, at or before the written confirmation
         of such sale, a copy of the prospectus (excluding the





                                     - 14 -
<PAGE>   64

         documents incorporated by reference) or of the prospectus as then
         amended or supplemented (excluding documents incorporated by
         reference) if the Company has previously furnished copies thereof to
         such holder in compliance with this Agreement and the loss, claim,
         damage, liability or expense of such Company Indemnified Party results
         from an untrue statement or omission of a material fact contained in
         such preliminary prospectus which was corrected in the prospectus (or
         the prospectus as amended or supplemented).  Such indemnity obligation
         shall remain in full force and effect regardless of any investigation
         made by or on behalf of the Company Indemnified Parties (except as
         provided above) and shall survive the transfer of such securities by
         such holder.

                 (c)         Conduct of Indemnification Proceedings.  Promptly
         after receipt by an identified party under Sections 12(a) or 12(b)
         above of written notice of the commencement of any action, suit,
         proceeding, investigation or threat thereof with respect to which a
         claim for indemnification may be made pursuant to this Section, such
         indemnified party shall, if a claim in respect thereto is to be made
         against an indemnifying party, give written notice to the indemnifying
         party of the threat or commencement thereof, provided, however, that
         the failure to so notify the indemnifying party shall not relieve it
         from any liability which it may have to any indemnified party except
         to the extent that the indemnifying party is actually prejudiced by
         such failure to give notice.  If any such claim or action referred to
         under Sections 12(a) or 12(b) above is brought against any indemnified
         party and it then notifies the indemnifying party of the threat or
         commencement thereof, the indemnifying party shall be entitled to
         participate therein and, to the extent that it wishes, jointly with
         any other indemnifying party similarly notified, to assume the defense
         thereof with counsel reasonably satisfactory to such indemnified party
         (who shall not, except with the consent of the indemnified party, be
         counsel to the indemnifying party).  After notice from the
         indemnifying party to such indemnified party of its election so to
         assume the defense of any such claim or action, the indemnifying party
         shall not be liable to such indemnified party under this Section 12
         for any legal expenses of counsel or any other expenses (other than
         reasonable costs of investigation) subsequently incurred by such
         indemnified party in connection with the defense thereof, unless the
         indemnifying party has failed to assume the defense of such claim or
         action or to employ counsel reasonably satisfactory to such
         indemnified party.  Notwithstanding the foregoing, the indemnified
         party shall have the right to retain its own counsel, with the fees
         and expenses to be paid by the indemnifying party, if representation
         of such indemnified party by the counsel retained by the indemnifying
         party would be inappropriate due to actual or potential differing
         interests between such indemnified party and any other party
         represented by such counsel in such action.  The indemnifying party
         shall not be required to indemnify the indemnified party with respect
         to any amounts paid in settlement of any action, proceeding or
         investigation entered into without the written consent of the
         indemnifying party, which consent shall not be unreasonably delayed or
         withheld.  No indemnifying party shall consent to the entry of any
         judgment or enter into any settlement without the consent of the
         indemnified party unless (i) such judgment or settlement does not
         impose any obligation or liability upon the indemnified party other
         than the execution, delivery or approval thereof, and (ii) such
         judgment or settlement





                                     - 15 -
<PAGE>   65

         includes as an unconditional term thereof the giving by the claimant
         or plaintiff to such indemnified party of a full release and discharge
         from all liability in respect of such claim and a full release of all
         Persons that may be entitled to or obligated to provide
         indemnification or contribution under this Section.

                 (d)         Contribution.  If the indemnification provided for
         in this Section 12 is unavailable to or insufficient to hold harmless
         an indemnified party under Sections 12(a) or 12(b), then each
         indemnifying party shall contribute to the amount paid or payable by
         such indemnified party as a result of the losses, claims, damages,
         liabilities or expenses (or actions or proceedings in respect thereof)
         referred to in Sections 12(a) or 12(b) in such proportion as is
         appropriate to reflect the relative fault of the indemnifying party on
         the one hand and the indemnified party on the other in connection with
         the statements, omissions, actions or inactions which resulted in such
         losses, claims, damages, liabilities or expenses.  The relative fault
         of the indemnifying party and the indemnified party shall be
         determined by reference to, among other things, whether the untrue or
         alleged untrue statement of a material fact or the omission or alleged
         omission to state a material fact relates to information supplied by
         the indemnifying party or the indemnified party, any action or
         inaction by any such party, and the parties' relative intent,
         knowledge, access to information and opportunity to correct or prevent
         such statement, omission, action or inaction.  The amount paid or
         payable by an indemnified party as a result of the losses, claims,
         damages, liabilities or expenses (or actions or proceedings in respect
         thereof) pursuant to this Section 12(d) shall be deemed to include any
         reasonable legal or other expenses incurred by such indemnified party
         in connection with investigating or defending any such action or claim
         (which shall be limited as provided in Section 12(c) if the
         indemnifying party has assumed the defense of any such action in
         accordance with the provisions thereof) which is the subject of this
         Section 12(d).  No Person guilty of fraudulent misrepresentation
         (within the meaning of Section 11(f) of the Securities Act) shall be
         entitled to contribution from any Person who was not guilty of such
         fraudulent misrepresentation.  Promptly after receipt by an
         indemnified party under this Section 12(d) of written notice of the
         commencement of any action, suit, proceeding, investigation or threat
         thereof with respect to which a claim for contribution may be made
         against an indemnifying party under this Section 12(d), such
         indemnified party shall, if a claim for contribution in respect
         thereto is to be made against an indemnifying party, give written
         notice to the indemnifying party of the commencement thereof (if the
         notice specified in Section 12(c) has not been given with respect to
         such action), provided, however, that the failure to so notify the
         indemnifying party shall not relieve it from any obligation to provide
         contribution which it may have to any indemnified party under this
         Section 12(d), except to the extent that the indemnifying party is
         actually prejudiced by the failure to give notice.  The parties hereto
         agree that it would not be just and equitable if contribution pursuant
         to this Section 12(d) were determined by pro rata allocation or by any
         other method of allocation which does not take account of the
         equitable considerations referred to in this Section 12(d).

                 If indemnification is available under this Section 12, the
         indemnifying parties shall indemnify each indemnified party to the
         fullest extent provided in Sections 12(a)





                                     - 16 -
<PAGE>   66

         and 12(b) hereof, without regard to the relative fault of said
         indemnifying party or indemnified party or any other equitable
         consideration provided for in this Section 12(d).  The provisions of
         this Section 12(d) shall be in addition to any other rights to
         indemnification or contribution which any indemnified party may have
         pursuant to law or contract, shall remain in full force and effect
         regardless of any investigation made by or on behalf of any
         indemnified party, and shall survive the transfer of securities by any
         such party.

                 (e)         Indemnification and Contribution of Underwriters.
         In connection with any underwritten offering contemplated by this
         Agreement which includes Registrable Securities, the Company and all
         sellers of Registrable Securities included in any registration
         statement shall agree to customary provisions for indemnification and
         contribution (consistent with the other provisions of this Section 12)
         in respect of losses, claims, damages, liabilities and expenses of the
         underwriters of such offering.

                 (f)         Aggregate Liability of the Holders of Registrable
         Securities.  The aggregate amount which any holder of Registrable
         Securities shall be required to pay pursuant to this Section 12,
         pursuant to any representation or warranty provided in connection
         with, or indemnity, contribution or reimbursement agreements executed
         in connection with, any underwritten offering, or pursuant to any
         other transactions contemplated hereby or thereby shall be limited to
         the amount of proceeds received by such holder upon the sale of the
         Registrable Securities and other securities of the Company (after
         deducting any underwriting commissions, discounts, transfer taxes and
         expenses applicable thereto) pursuant to the registration statement
         giving rise to such claim.

         SECTION 13.         Termination.

         This Agreement shall terminate on the date on which the Purchaser and
the Purchaser Affiliates hold, in the aggregate, Registrable Securities
representing less than two percent (2%) of the total number of outstanding

         breach of any provision of this Agreement and to exercise all other
         rights granted by law.  The parties hereto agree and acknowledge that

         discretion apply to any court of law or equity of competent
         jurisdiction (without posting any bond or other security) for specific
         performance and for other injunctive relief in order to enforce or
         prevent violation of the provisions of this Agreement.

                 (h)         Public Announcements.  Except as otherwise

         to the subject matter hereof and contains the sole and entire
         agreement among the parties hereto with respect to the subject matter

                             RIGHT OF FIRST REFUSAL

         SECTION 3.1  Grant of Right.  If at any time a Stockholder (a "Selling
Stockholder") proposes to sell or transfer Voting Stock in any manner, directly
or indirectly, to any Person, other than pursuant to a Permitted Transfer in
accordance with the terms of Section 3.2 hereof, then each of the other
Stockholders (a "Purchasing Stockholder") shall have a right of first refusal
to purchase its Prorata Percentage of the shares of such Voting Stock, on the
terms pursuant to which such Selling Stockholder proposes to sell or transfer
such Voting Stock, in accordance with the following procedure:

                 (a)      Notice to Purchasing Stockholders.  In the event a
         Selling Stockholder proposes to sell or transfer Voting Stock in a
         transaction that would be subject to the foregoing right of first
         refusal, such Selling Stockholder shall give each Purchasing
         Stockholder written notice (the " Voting Stock Notice") of its
         intentions stating (i) a description of the Voting Stock proposed to be
         sold or transferred and the identity of the transferee, (ii) the total
         number of shares of Voting Stock proposed to be sold or transferred,
         (iii) the price per share at which, and the other terms on which, such
         Voting Stock is proposed to be sold or transferred, and (iv) the date
         of such notice.

                 (b)      Exercise by Purchasing Stockholders.  Within thirty
         (30) days after the Voting Stock Notice is given to each Purchasing
         Stockholder, such Purchasing Stockholder may elect to purchase, at the
         price and on the terms specified in the Voting Stock Notice, the
         number of shares of Voting Stock proposed to be sold or transferred by
         the Selling Stockholder determined by multiplying all shares of Voting
         Stock proposed to be sold or transferred by the Prorata Percentage of
         such Purchasing Stockholder.  An election to purchase shall be made by
         the Purchasing Stockholder in writing and must be given to the Selling
         Stockholder within such thirty (30) day period.  Any such election
         made by a Purchasing Stockholder shall constitute an





                                     - 5 -
<PAGE>   82

         irrevocable, legally binding obligation of such Purchasing Stockholder
         to purchase its Prorata Percentage of the Voting Stock on the terms
         set forth in the Voting Stock Notice, and the Purchasing Stockholder
         and the Selling Stockholder shall use their best efforts to secure any
         approvals required in connection therewith.  The closing of the sale
         of the Voting Stock by the Selling Stockholder to a Purchasing
         Stockholder upon the exercise of its rights under this Section 3.1
         shall take place within thirty (30) days following the date on which
         such election to purchase is made, provided that such period shall be
         extended, as required, in order to comply with applicable Laws.

                 (c)      Back-Up Right.  If any Purchasing Stockholder does
         not exercise its right of first refusal to purchase shares of Voting
         Stock hereunder within the time specified for such exercise (including
         its failure to exercise the right granted in this subsection (c)),
         such Purchasing Stockholder shall immediately so notify all other
         Purchasing Stockholders, and each of the other Purchasing Stockholders
         shall have the right to purchase its Prorata Percentage of such shares
         of Voting Stock (determined without counting the shares of Voting
         Stock owned by the Purchasing Stockholder not exercising its right of
         first refusal) within a period of five (5) days following the date on
         which such notice is given.

                 (d)      Failure to Exercise.  The Selling Stockholder shall
         be free, subject to the co-sale rights set forth in Article IV hereof,
         during the period of ninety (90) days following the expiration of all
         rights of first refusal set forth in this Section 3.1, to sell or
         transfer the Voting Stock specified in the Voting Stock Notice
         previously delivered to each Purchasing Stockholder which is not
         purchased by Purchasing Stockholders to the proposed transferee(s)
         described in the Voting Stock Notice and on terms no less favorable to
         the Selling Stockholder than the terms specified in the Voting Stock
         Notice.  The proposed sale or transfer of any such Voting Stock not
         sold or transferred by the Selling Stockholder to such transferee(s)
         within such ninety (90) day period shall again be subject to the
         restrictions set forth in this Section 3.1.

         SECTION 3.2  Permitted Transfers of Voting Stock.  The right of first
refusal contained in Section 3.1 hereof shall not apply to any sale or transfer
of Voting Stock made by a Selling Stockholder (a "Permitted Transfer"):  (i) to
another Stockholder or an Affiliate of another Stockholder, (ii) pursuant to a
bona fide public offering registered under the Securities Act of either Voting
Stock or securities exchangeable or exercisable for Voting Stock or, if such
securities being sold or transferred are registered under the Securities Act,
in any other public market transaction, (iii) pursuant to Rule 144 (but
excluding Rule 144A promulgated under the Securities Act), (iv) pursuant to any
repurchase by the Company, (v) pursuant to any bona fide gift to a charitable
organization, (vi) pursuant to any transfer to a Selling Stockholder's
ancestors, descendants, spouse or to a trustee for their benefit, (vii)
pursuant to community property or similar domestic relations laws, or (viii) if
the Purchaser is the Selling Stockholder, to an Affiliate of the Purchaser.
Notwithstanding the foregoing, any proposed sale or transfer pursuant to
subparagraph (vii) of this Section 3.2 shall not qualify as a Permitted
Transfer (and shall therefore be subject to the rights of first refusal in
Section 3.1) unless such Selling Stockholder notifies the Company and the
Stockholders (other than the Selling Stockholder) of such sale or transfer and
the proposed transferee furnishes the Company and the Stockholders (other than
the Selling Stockholder) with a





                                     - 6 -

written agreement to be bound by and comply with all provisions of this
Agreement applicable to the Selling Stockholder prior to receiving the Voting
Stock being transferred.  In addition, notwithstanding the foregoing, any
proposed sale or transfer pursuant to subparagraphs (ii) or (iii) of this
Section 3.2 shall not qualify as a Permitted Transfer (and shall therefore be
subject to the rights of first refusal in Section 3.1) if the Selling
Stockholder solicits or arranges for the solicitation of orders to purchase
such Voting Stock by a Restricted Investor from an underwriter in anticipation
of or in connection with a registered public offering or from or through a
broker in anticipation of or in connection with a Rule 144 transaction or other
public market transaction, provided that the execution and performance of an
underwriting agreement by the Selling Stockholder in connection with a
registered public offering shall not, in and of itself, be considered
soliciting or arranging for the solicitation of orders to purchase Voting
Stock.  Simultaneous with any transfer described in subparagraph (v) or (vi),
the Selling Stockholder shall certify to each Stockholder (other than the
Selling Stockholder) that such transfer is not intended to indirectly complete
any transfer that would otherwise be restricted pursuant to this Article III.

         SECTION 3.3  Liquidation of Venture America.  The Stockholders and the
Company acknowledge that Venture America Management Limited Partnership, a
Virginia limited partnership and a Current Stockholder ("Venture America"),
will undergo a complete liquidation on or before December 31, 1996, and that,
in connection therewith, the 250,366 shares of Common Stock currently owned by
Venture America will be distributed to the following partners thereof in
approximately equal amounts:  Daniel E. Moore, James R. Ball, Otis F. Coston.

         The provisions in this Article III shall not apply to the transfer of
such shares of Common Stock by Venture America to the foregoing individuals in
connection with the liquidation of Venture America described above, provided
that, in the case of any transfer to Mr. Ball or Mr. Coston, such individual
and, if legally necessary or appropriate, his spouse (if any) agrees in writing
to be bound by all provisions of this Agreement binding on a Current
Stockholder and that a copy of such agreement is delivered to each party hereto
before such transfer.

         SECTION 3.4  No Adverse Effect for Failure to Purchase.  The exercise
or non-exercise of its right of first refusal by any Purchasing Stockholder
hereunder in one or more cases shall not adversely affect such Purchasing
Stockholder's right to exercise such right of first refusal with respect to any
subsequent proposed sale or transfer of Voting Stock by a Selling Stockholder
pursuant to this Article III.


                                   ARTICLE IV

                                RIGHT OF CO-SALE

         SECTION 4.1  Grant of Right.  If at any time a Selling Stockholder
proposes to sell or transfer any Voting Stock in any manner, directly or
indirectly, to any Person, other than pursuant to a Permitted Transfer, and if
all shares of such Voting Stock are not purchased pursuant to the exercise of
the rights of first refusal with respect to such proposed sale or





                                     - 7 -

transfer set forth in Section 3.1 hereof, then each Purchasing Stockholder
shall have the right, exercisable by giving written notice to the Selling
Stockholder, within ten (10) days after the expiration of all unexercised
rights of first refusal pursuant to Sections 3.1(b) and (c), to participate in
such sale or transfer of Voting Stock by the Selling Stockholder on the terms
set forth in the Voting Stock Notice previously provided to such Purchasing
Stockholder pursuant to Section 3.1.  If any Purchasing Stockholder exercises
such right of participation, the number of shares of Voting Stock which such
Selling Stockholder may sell or transfer shall be correspondingly reduced.  The
right of participation of each Purchasing Stockholder shall be subject to the
following additional terms and conditions:

                 (a)      Calculation of Shares.  The number of shares of
         Voting Stock which the Purchasing Stockholder may sell or transfer (in
         whole or in part) shall be determined by multiplying (i) the aggregate
         number of shares of Voting Stock which the Selling Stockholder
         proposes to sell or transfer (following the exercise or the
         expiration, as the case may be, of the rights of first refusal set
         forth in Section 3.1) by (ii) a fraction, the numerator of which is
         the number of shares of Voting Stock owned by the Purchasing
         Stockholder as of the date of the Voting Stock Notice and the
         denominator of which is the total number of shares of Voting Stock
         owned by all Stockholders as of the date of the Voting Stock Notice.

                 (b)      Delivery of Certificates.  At the closing of the sale
         or transfer of the Voting Stock to the transferee, each Purchasing
         Stockholder electing to participate therein pursuant to this Section
         4.1 shall deliver to the Selling Stockholder for transfer to the
         transferee one or more stock certificates, properly endorsed for
         transfer, which represent the number of shares of Voting Stock which
         such Purchasing Stockholder elects to sell pursuant to this Section
         4.1.

         SECTION 4.2  Transfer of Sale Proceeds.  The stock certificate or
certificates which each Purchasing Stockholder delivers to the Selling
Stockholder pursuant to Section 4.1(b) shall be delivered by the Selling
Stockholder to the transferee in consummation of the sale or transfer pursuant
to the terms and conditions specified in the Voting Stock Notice, and the
Selling Stockholder shall promptly thereafter remit to such Purchasing
Stockholder that portion of the sale proceeds to which the Purchasing
Stockholder is entitled by reason of its participation in such sale.

         SECTION 4.3  Liquidation of Venture America.  The provisions in this
Article IV shall not apply to any transfer of shares of Common Stock in
connection with the liquidation of Venture America which satisfies the
requirements of Section 3.3.

         SECTION 4.4  No Adverse Effect for Failure to Participate.  The
exercise or non-exercise of its co-sale rights by any Purchasing Stockholder
hereunder in one or more cases shall not adversely affect such Purchasing
Stockholder's right to exercise such right of co-sale with respect to any
subsequent proposed sale or transfer of Voting Stock by a Selling Stockholder
pursuant to this Article IV.

                              BOARD REPRESENTATION
                             AND OBSERVATION RIGHTS

         SECTION 5.1  Designation of Nominee by Purchaser.  At least thirty
(30) days prior to establishing the date for any annual or special meeting of
stockholders of the Company at which the Board of directors of the Company (the
"Board") will be elected (an "Election Meeting") the Company shall notify the
Purchaser of its intent to establish such date.  Upon its receipt of such
notice, the Purchaser shall have the right, but not the obligation, to
designate an individual who may, but need not be, an employee of the Purchaser
or an Affiliate of the Purchaser (the "Purchaser Nominee") for nomination to
the Board.  The Company and the Current Stockholders shall use their best
efforts to cause the Purchaser Nominee to be nominated (including, but not
limited to, making the Purchaser Nominee a member of the recommended management
slate of directors) for election to the Board at such Election Meeting and
elected thereat.  In addition, each Current Stockholder agrees to vote (whether
in person or by proxy) all shares of Voting Stock of the Company owned or held
of record by such Current Stockholder at any Election Meeting in favor of the
election of the Purchaser Nominee to the Board.

         In the event that any Purchaser Nominee is elected to the Board (the
"Purchaser Director") and thereafter such Purchaser Director dies, resigns, or
is removed (with or without cause) from the Board, then the Purchaser shall
have the right, but not the obligation, to designate a successor Purchaser
Director (the "Successor Purchaser Director") to fill the vacancy on the Board.
In the event the Purchaser designates such Successor Purchaser Director, the
Company and the Current Stockholders shall use their best efforts to cause the
remaining directors on the Board to elect the Successor Purchaser Director in
accordance with the certificate of incorporation and by-laws of the Company and
the Delaware General Corporation Law ("DGCL") as the successor director to hold
office for the unexpired portion of the term of the Purchaser Director.  In
addition, if the stockholders of the Company have the right to appoint a
successor director pursuant to the terms of the certificate of incorporation
and by-laws of the Company and the DGCL, then the Company and the Current
Stockholders shall use their best efforts to cause the stockholders of the
Company to appoint the Successor Purchaser Director as the successor to the
Purchaser Director and, in connection therewith, each Current Stockholder
agrees to vote (whether in person or by proxy) all shares of Voting Stock of
the Company owned or held of record by such Stockholder in favor of the
appointment of the Successor Purchaser Director as the successor to the
Purchaser Director.

         SECTION 5.2  Indemnification and Insurance.  The Company shall
indemnify and hold harmless each of the Purchaser Nominee, the Purchaser
Director and the Successor Purchaser Director from and against any and all
Losses arising out of or related to his service as a director of the Company or
any Affiliate of the Company to the maximum extent permitted by Law (including,
without limitation, the DGCL), the certificate of incorporation of the Company
and the bylaws of the Company.  In addition, throughout the term of this
Agreement, the Company shall maintain in effect directors and officers
liability insurance covering each of the Purchaser Nominee, the Purchaser
Director and the Successor Purchaser





                                     - 9 -
<PAGE>   86

Director in his capacity as a director of the Company and providing the
following minimum benefits: $3,000,000 combined limits.  The obligations of the
Company in this Section 5.2 shall survive the termination of this Agreement.
The Company shall not, without the prior written consent of the Purchaser, (i)
amend any provision of its certificate of incorporation or bylaws pertaining to
the indemnification of directors, or (ii) reduce the minimum benefits under the
foregoing directors insurance.

         SECTION 5.3  Observation Rights.  If at any time neither a Purchaser
Nominee (or a Purchaser Director) nor a Successor Purchaser Director is serving
on the Board, the Purchaser shall have the right to have a representative
designated by it attend all meetings of the Board and observe all proceedings
transacted at such meetings.  The Company shall provide to such representative
copies of all notices, minutes, consents, and other materials that it provides
to its directors at the same time it provides such information to directors.
Notwithstanding the foregoing, the Company reserves the right to exclude such
representative from any meeting or any part thereof if the Company believes,
upon advice of counsel, that such exclusion is reasonably necessary to preserve
the attorney-client privilege, to protect highly confidential proprietary
information or for other similar reasons.


                                   ARTICLE VI

                         REPRESENTATIONS AND WARRANTIES

         III, the Purchaser will acquire good and valid title to all such shares

         all Liens.

                 (b)      Stock Rights.  Except as disclosed on Exhibit B, the
         Representing Stockholder is not a party to or bound by, or the
         beneficiary of, (i) any outstanding subscriptions, options, warrants,

         first refusal) or Contracts, orally or in writing, obligating the
         Company or any of its Subsidiaries, contingently or otherwise, to

         Stockholder to purchase or sell any capital stock or other security of
         the Company or any of its Subsidiaries, which affects or relates to
         the voting or giving of written consents with respect to any capital
         stock or other security of the Company or any of its Subsidiaries or

         IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO

                                   ARTICLE X

         The parties hereto shall attempt to settle all disputes arising in
connection with this Agreement through good faith negotiations.  In the event
any such dispute cannot be resolved within sixty (60) days after any party
involved in such dispute notifies the other parties involved in such dispute
that the dispute is to be resolved pursuant to this Article X, then any such
party may submit such dispute to arbitration.  Any dispute submitted to
arbitration pursuant to this Article X shall be finally and conclusively
determined in accordance with the Rules of Arbitration of the International
Chamber of Commerce (the "Rules of Arbitration") then in effect by the decision
of three (3) arbitrators selected in accordance with the Rules of Arbitration,
unless the parties shall agree on a single arbitrator (the "Board of
Arbitration").  The Board of Arbitration shall meet in New York, New York and
shall render a decision in writing (concurred in by a majority of the members
of the Board of Arbitration if more than one) with respect to and stating the
amount, if any, which any party hereto is required to pay to any other party
hereto in respect of such dispute.  To the extent practical, the decision of
the Board of Arbitration shall be rendered no more than thirty (30) days
following commencement of proceedings with respect thereto.  The Board of
Arbitration shall cause its written decision to be delivered to each of the
parties involved in such dispute.  Any decision made by the Board of
Arbitration (either prior to or after the expiration of such thirty (30) day
period) shall be final, binding and conclusive on the parties hereto and
entitled to be enforced to the fullest extent permitted by Law and entered in
any court of competent jurisdiction.

         All parties hereto hereby consent to the jurisdiction of the foregoing
Board of Arbitration and to the jurisdiction of any state or federal court
located in the States of New York or Delaware and any national court located in
France for the purpose of enforcing the decision or award of the Board of
Arbitration.  All parties hereto agree that service of process may be made on
any such party by personal delivery or by registered or certified mail
addressed to the appropriate party at the address for such party specified in
Section 11.1 hereof.  The submission to the jurisdiction of the courts referred
to above for the purpose of enforcing the decision or award of the Board of
Arbitration shall not (and shall not be construed so as to) limit the right of
any party to file or commence proceedings against any other party in any other
court of competent jurisdiction for the purpose of enforcing the decision or
award of the Board of Arbitration nor shall the filing or commencement of
proceedings in any one or more jurisdictions for such purpose preclude the
filing or taking of proceedings in any other jurisdiction for such purpose
(whether concurrently or not) if and to





                                     - 14 -

commenced pursuant to this Article X shall be consolidated with any arbitration
proceeding then pending under this Article X.  All fees, costs and expenses in
relation to the arbitration, including, but not limited to, attorneys' fees
shall be paid by such parties as determined by the Board of Arbitration.

                                   ARTICLE II

                              BOARD REPRESENTATION

     At least thirty (30) days prior to establishing the date for any annual or
special meeting of stockholders of the Company at which the Board of Directors
of the Company (the "Board") will be elected (an "Election Meeting") the Company
shall notify the Purchaser of its intent to establish such date.  Upon its
receipt of such notice, the Purchaser shall have the right, but not the
obligation, to designate an individual who may, but need not be, an employee of
the Purchaser or an Affiliate of the Purchaser (the "Purchaser Nominee") for
nomination to the Board.  The Company and the Stockholders shall use their best
efforts to cause the Purchaser Nominee to be nominated (including, but not
limited to, making the Purchaser Nominee a member of the recommended management
slate of directors) for election to the Board at such Election Meeting and
elected thereat.  In addition, each Stockholder agrees to vote (whether in
person or by proxy) all shares of Voting Stock of the Company owned or held of
record by such Stockholder at any Election Meeting in favor of the election of
the Purchaser Nominee to the Board.

     In the event that any Purchaser Nominee is elected to the Board (the
"Purchaser Director") and thereafter such Purchaser Director dies, resigns, or
is removed (with or without cause) from the Board, then the Purchaser shall have
the right, but not the obligation, to designate a successor Purchaser Director
(the "Successor Purchaser Director") to fill the vacancy on the Board.  In the
event the Purchaser designates such Successor Purchaser Director, the Company
and the Stockholders shall use their best efforts to cause the remaining
directors on the Board to elect the Successor Purchaser Director in accordance
with the certificate of incorporation and by-laws of the Company and the
Delaware General Corporation Law ("DGCL") as the successor director to hold
office for the unexpired portion of the term of the Purchaser Director.  In
addition, if the stockholders of the Company have the right to appoint a
successor director pursuant to the terms of the certificate of incorporation and
by-laws of the Company and the DGCL, then the Company and the Stockholders shall
use their best efforts to cause the stockholders of the Company to appoint the
Successor Purchaser Director as the successor to the Purchaser Director and, in
connection therewith, each Stockholder agrees to vote (whether in person or by
proxy) all shares of Voting Stock of the Company owned or held of record by such
Stockholder in favor of the appointment of the Successor Purchaser Director as
the successor to the Purchaser Director.
