            REVOLVING CREDIT AGREEMENT dated as of December 15, 1995, as amended
on March 25, 1996, among GLOBALSTAR, L.P., a Delaware limited partnership (the
"Borrower"), the several financial institutions parties from time to time to
this Agreement (collectively, the "Banks"; individually, a "Bank") and CHEMICAL
BANK, a New York banking corporation ("Chemical"), as administrative agent for
the Banks hereunder (in such capacity, the "Administrative Agent").

                              W I T N E S S E T H :

            WHEREAS, the Borrower has requested the Banks to make revolving
credit loans to the Borrower, the proceeds of which will be used to finance (i)
the buildout of a global satellite communications system by the Borrower, (ii)
interest payments when due on the Loans made pursuant to this Agreement and
(iii) working capital needs; and

            WHEREAS, the Banks are willing to make such Loans to the Borrower
upon the terms and subject to the conditions hereinafter set forth;

            NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained, the parties hereto hereby agree as follows:

            SECTION 1.  DEFINITIONS

            1.1  Defined Terms.  As used in this Agreement, the following
terms have the following meanings:

            "ABR Loans":  Loans the rate of interest applicable to which is
based upon the ABR.

            "ABR": for any day, a rate per annum (rounded upwards, if necessary,
to the next 1/16 of 1%) equal to the greatest of (a) the Prime Rate in effect on
such day, (b) the Base CD Rate in effect on such day plus 1% and (c) the Federal
Funds Effective Rate in effect on such day plus 1/2 of 1%. For purposes hereof:
"Prime Rate" shall mean the rate of interest per annum publicly announced from
time to time by Chemical as its prime rate in effect at its principal office in
New York City (the Prime Rate not being intended to be the lowest rate of
interest charged by Chemical in connection with extensions of credit to
debtors); "Base CD Rate" shall mean the sum of (a) the product of (i) the
Three-Month Secondary CD Rate and (ii) a fraction, the numerator of which is one
and the denominator of which is one minus the CD Reserve Percentage and (b) the
CD Assessment Rate; "Three-Month Secondary CD Rate" shall mean, for any day, the
secondary market rate for three-month certificates of deposit reported as being
in effect on such day (or, if such day shall not be a Business Day, the next
preceding Business Day) by the Board of Governors of the Federal Reserve System
(the "Board") through the public information telephone line of the Federal
Reserve Bank of New
<PAGE>   6
York (which rate will, under the current practices of the Board, be published in
Federal Reserve Statistical Release H.15(519) during the week following such
day), or, if such rate shall not be so reported on such day or such next
preceding Business Day, the average of the secondary market quotations for
three-month certificates of deposit of major money center banks in New York City
received at approximately 10:00 A.M., New York City time, on such day (or, if
such day shall not be a Business Day, on the next preceding Business Day) by the
Administrative Agent from three New York City negotiable certificate of deposit
dealers of recognized standing selected by it; "CD Assessment Rate" shall mean,
for any day, the annual assessment rate in effect on such day which is payable
by a member of the Bank Insurance Fund maintained by the FDIC classified as
well-capitalized and within supervisory subgroup "A" (or a comparable successor
assessment risk classification) within the meaning of 12 C.F.R. Section 327.3(d)
(or any successor provision) to the FDIC for the FDIC's insuring time deposits
at offices of such institution in the United States; "CD Reserve Percentage"
shall mean, for any day, that percentage (expressed as a decimal) which is in
effect on such day, as prescribed by the Board, for determining the maximum
reserve requirement for a Depositary Institution (as defined in Regulation D of
the Board) in respect of new non-personal time deposits in Dollars having a
maturity of 30 days or more; and "Federal Funds Effective Rate" shall mean, for
any day, the weighted average of the rates on overnight federal funds
transactions with members of the Federal Reserve System arranged by federal
funds brokers, as published on the next succeeding Business Day by the Federal
Reserve Bank of New York, or, if such rate is not so published for any day which
is a Business Day, the average of the quotations for the day of such
transactions received by the Administrative Agent from three federal funds
brokers of recognized standing selected by it. If for any reason the
Administrative Agent shall have determined (which determination shall be
conclusive absent manifest error) that it is unable to ascertain the Base CD
Rate or the Federal Funds Effective Rate, or both, for any reason, including the
inability or failure of the Administrative Agent to obtain sufficient quotations
in accordance with the terms thereof, the ABR shall be determined without regard
to clause (b) or (c), or both, of the first sentence of this definition, as
appropriate, until the circumstances giving rise to such inability no longer
exist. Any change in the ABR due to a change in the Prime Rate, the Three-Month
Secondary CD Rate, the CD Reserve Percentage, the CD Assessment Rate or the
Federal Funds Effective Rate shall be effective as of the opening of business on
the effective day of such change in the Prime Rate, the Three-Month Secondary CD
Rate, the CD Reserve Percentage, the CD Assessment Rate or the Federal Funds
Effective Rate, respectively.

            "Acceptable Letter of Credit": a letter of credit, substantially in
the form of Exhibit G hereto, which satisfies the following conditions: (A) such
letter of credit supports a fixed amount of principal of the Loans plus up to

<PAGE>   7
accrued interest on such principal amount calculated at a rate equal to 8% per
annum and based on an assumed year of 360 days, (B) such letter of credit is
issued by a bank which has an unsecured senior long-term debt rating of at least
A from S&P and A2 from Moody's, (C) the issuer of such letter of credit is
approved by the Majority Banks at the time of issuance, which approval shall not
be unreasonably withheld, (D) such letter of credit is issued for the account of
one or more Partners, (E) such letter of credit is issued in favor of the
Administrative Agent for the benefit of the Banks and (F) at the time of its
delivery to the Administrative Agent (i) such letter of credit is accompanied by
legal opinions, resolutions and comparable documents with respect to such letter
of credit and the issuer thereof requested by the Administrative Agent and (ii)
the Applicable Partner delivers to the Administrative Agent a Partner Cash
Collateral Agreement, legal opinions, resolutions, financing statements and
comparable documents with respect to such Applicable Partner and Partner Cash

Credit during any time that the condition set forth in clause (B) of the
preceding sentence is not satisfied.

Indebtedness as Additional Buildout Indebtedness at the time it is created or
incurred.

            SECTION 2. AMOUNT AND TERMS OF COMMITMENTS

            2.1 Revolving Credit Commitments. (a) Subject to the terms and
conditions hereof, each Bank severally agrees to make revolving credit loans
(the "Loans") to the Borrower from time to time during the Commitment Period in
an aggregate principal amount at any one time outstanding not to exceed such
Bank's Commitment. During the Commitment Period the Borrower may use the
Commitments by borrowing, prepaying the Loans in whole or in part, and
reborrowing, all in accordance with the terms and conditions hereof.

            (b) The Loans may from time to time be (i) Eurodollar Loans, (ii)
ABR Loans or (iii) a combination thereof, as determined by the Borrower and
notified to the Administrative Agent in accordance with Sections 2.3 and 2.8;
provided, that no Loan shall be made as a Eurodollar Loan after the day that is
one month prior to the Termination Date.

            2.2 Commitment/Loan Support. (a) Payment of all of the Guaranteed
Obligations shall be, prior to the Release Date, supported by the Lockheed
Martin Guarantee or, in lieu thereof, by Acceptable Letters of Credit (and,
after a drawing on an Acceptable Letter of Credit or Downgraded Letter of
Credit, by Partner Cash Collateral), provided that (a) no more than 60% of the
Guaranteed Obligations shall be supported at any time by Partner Guarantees
(other than the Lockheed Martin Guarantee) and (b) no less than 40% of the
Guaranteed Obligations shall be supported at any time by the Lockheed Martin
Guarantee. In addition, at all times prior to the Release Date, payment of all
of the Guaranteed Obligations will be supported by the Subsidiary


                                       20
<PAGE>   25
Guarantee executed by each domestic Subsidiary in existence prior to the Release
Date.

            (b) Subject to the provisions of paragraph (a) above and the other
provisions of this Section 2.2, the maximum liability of Lockheed Martin under
the Lockheed Martin Guarantee in respect of principal of and interest on the
Loans shall be reduced by the available amount (i.e., at any time, the amount
that may be drawn under each Letter of Credit at such time and, if a drawing has
been made by the Administrative Agent under such Letter of Credit, the sum of
the amount of principal of the Loans in respect of which such drawing was made
plus the amount of unpaid accrued interest on such principal amount at such time
deposited in a Partner Collateral Account) of each Acceptable Letter of Credit
(and, if such Acceptable Letter of Credit becomes a Downgraded Letter of Credit,
such Downgraded Letter of Credit) delivered to the Administrative Agent by
another Partner Guarantor. In the event that (i) any Partner Guarantor shall be
insolvent or bankrupt or any of the events of the type described in clause (vi)
of paragraph (a) of Section 8 shall occur with respect to such Partner Guarantor
and (ii) such Partner Guarantor has delivered any Partner Cash Collateral
pursuant to a drawing by the Administrative Agent under a Letter of Credit
issued for the account of such Partner Guarantor, then upon the occurrence of
any of the events described in clause (i) the maximum liability of Lockheed
Martin under the Lockheed Martin Guarantee shall be increased by an amount equal
to the aggregate amount of the drawing made by the Administrative Agent under
such Letter of Credit.

            (c) Upon the termination or expiration of the Commitments or
acceleration of the Loans under Section 8 or maturity of the Loans on the
Termination Date, the Administrative Agent shall use reasonable efforts to call
on the Partner Guarantees, whether by notice or demand in the case of the
Lockheed Martin Guarantee, or, in the case of a Letter of Credit, by drawing
thereunder in conformity with the terms and conditions thereof, or, in the case
of Partner Cash Collateral, by withdrawal from the applicable Partner Collateral
Account (unless the Administrative Agent is prohibited from doing so because
such Partner is the subject of insolvency proceedings) (x) at approximately the
same time, to the extent practical and to the extent permitted by law, provided
that the failure to so call or draw at approximately the same time shall not
affect the obligations of the Loan Parties (including Lockheed Martin) under the
Loan Documents or of any issuer of a Letter of Credit thereunder or of any other
Partner Guarantor with respect to its Partner Cash Collateral, and (y) to the
extent practical and to the extent permitted by law, on a pro rata basis based
on the respective principal amounts of the Loans supported by each such
Guarantee (which, in the case of Partner Cash Collateral, shall be the principal
amount of the Loans supported by the Letter of Credit which funded such Partner
Cash Collateral), provided that this clause (y) shall not apply to calls made on
the Lockheed


                                       21
<PAGE>   26
Martin Guarantee for amounts in respect of which the other Partner Guarantees
are inapplicable, and provided that the failure to so call or draw on a pro rata
basis shall not affect the obligations of the Loan Parties (including Lockheed
Martin) under the Loan Documents or of any issuer of an Acceptable Letter of
Credit thereunder. The preceding sentence shall not apply with respect to
drawings made pursuant to paragraphs (d) and (e) below.

            (d) Unless any Expiring Letter of Credit is replaced by the
Applicable Partner with one or more Acceptable Letters of Credit with an equal
aggregate stated amount at least 30 days prior to the then scheduled expiration
date thereof, the Administrative Agent shall use reasonable efforts to draw upon
such Expiring Letter of Credit. All proceeds thereof shall be deposited to a
Partner Collateral Account established for the Applicable Partner.

            (e) The Administrative Agent shall use reasonable efforts to draw
the full amount of each Downgraded Letter of Credit promptly following its
actual knowledge that an Acceptable Letter of Credit has become a Downgraded
Letter of Credit unless such Downgraded Letter of Credit is replaced by the
Applicable Partner prior to such draw with one or more Acceptable Letters of
Credit with an equal aggregate stated amount; provided that the Administrative
Agent shall not draw on such Downgraded Letter of Credit during the 45 day
period after it obtains such knowledge (unless Obligations are otherwise due) if
the Borrower or the Applicable Partner notifies the Administrative Agent that it
is attempting to provide replacement Acceptable Letters of Credit (unless such
Letter of Credit will expire within 30 days). All proceeds of any such drawing
shall be deposited to a Partner Collateral Account established for the
Applicable Partner. If (i) the issuer of such Downgraded Letter of Credit is
insolvent or bankrupt or any of the events described in clause (vi) of paragraph
(a) of Section 8 shall occur with respect to such issuer, (ii) such issuer fails
to honor such drawing, (iii) the Administrative Agent is prevented by applicable
law from making such a drawing or (iv) amounts drawn under such Downgraded
Letter of Credit are required to be restored or returned by the Administrative
Agent or any Bank as a result of the insolvency, bankruptcy, dissolution,
liquidation or reorganization of the issuer of such Downgraded Letter of Credit
or upon or as a result of the appointment of a receiver, intervenor or
conservator of, or trustee or similar officer for, such issuer or any
substantial part of its property, or otherwise, then the maximum liability of
Lockheed Martin under the Lockheed Martin Guarantee shall be increased by an
amount equal to the stated amount of such Downgraded Letter of Credit.

            (f) All amounts, if any, credited to the Partner Collateral Accounts
shall be invested by the Administrative Agent in Collateral Cash Equivalents
(all such investments to be made in the name of the Administrative Agent) as
directed by the


                                       22
<PAGE>   27
Applicable Partner unless a Default or Event of Default has occurred and is
continuing. Unless a Default or an Event of Default has occurred and is
continuing, the Administrative Agent is authorized to:

                  (i) release net earnings on such investments, if any,
quarterly on the last day of each March, June, September and December, provided
that the Administrative Agent shall not release any earnings at any time unless
the balance of the Partner Cash Collateral remaining in such Partner Collateral
Account after giving effect to such release is at least equal to the proceeds of
the Administrative Agent's drawing(s) under the Letters of Credit delivered to
it for the account of the Applicable Partner;

                  (ii) release all Partner Cash Collateral to the Applicable
Partner upon delivery of one or more Acceptable Letters of Credit with an equal
aggregate stated amount to that of the Letters of Credit drawn upon by the
Administrative Agent to fund the related Partner Collateral Account;

                  (iii) release all Partner Cash Collateral to the Applicable
Partner upon the Guarantee Release; and

                  (iv) release the applicable Partner Cash Collateral to
Lockheed Martin (to the extent permitted by applicable law and applicable
Contractual Obligations) upon increase of liability of Lockheed Martin under the
Lockheed Martin Guarantee in accordance with this Section 2.2.

The Administrative Agent shall not be liable for any losses or decreases in
value with respect to the Partner Cash Collateral, other than those occurring as
a result of its gross negligence or willful misconduct.

             2.3 Procedure for Revolving Credit Borrowing. The Borrower may
borrow under the Commitments during the Commitment Period on any Eurodollar
Business Day, if all or any part of the requested Loans are to be initially
Eurodollar Loans, or on any Business Day, otherwise; provided, that the Borrower
shall give the Administrative Agent irrevocable notice (which notice must be
received by the Administrative Agent prior to 10:00 A.M., New York City time,
(a) with respect to any of the requested Loans that are to be initially
Eurodollar Loans, three Eurodollar Business Days prior to the requested
Borrowing Date or (b) with respect to any of the requested Loans that are to be
initially ABR Loans, on the requested Borrowing Date), specifying (i) the amount
to be borrowed, (ii) the requested Borrowing Date, (iii) whether the borrowing
is to be of Eurodollar Loans, ABR Loans or a combination thereof and (iv) if the
borrowing is to be entirely or partly of Eurodollar Loans, the respective
amounts of each such Loan and the respective lengths of the initial Interest
Periods therefor. Each borrowing under the Commitments shall be in an amount
equal to $10,000,000 or a whole multiple of


                                       23
<PAGE>   28
$1,000,000 in excess thereof or in the remaining amount of the Available
Commitments. Upon receipt of any such notice from the Borrower, the
Administrative Agent shall promptly notify each Bank thereof. Each Bank will
make the amount of its pro rata share of each borrowing available to the
Administrative Agent for the account of the Borrower at the office of the
Administrative Agent specified in Section 10.2 prior to 12:00 Noon, New York
City time, on the Borrowing Date requested by the Borrower in funds immediately
available to the Administrative Agent. Such borrowing will then be made
available to the Borrower by the Administrative Agent's crediting the account of
the Borrower on the books of such office with the aggregate of the amounts made
available to the Administrative Agent by the Banks and in like funds as received
by the Administrative Agent.

             2.4 Repayment of Loans; Evidence of Debt. (a) The Borrower hereby
unconditionally promises to pay to the Administrative Agent for the account of
each Bank the then unpaid principal amount of each Loan of the Borrower on the
Termination Date (or such earlier date on which the Loans become due and payable
pursuant to Section 2.6, 2.7 or 8). The Borrower hereby further agrees to pay
interest on the unpaid principal amount of the Loans from time to time
outstanding from the date hereof until payment in full thereof at the rates per
annum, and on the dates, set forth in subsection 2.10.

            (b) Each Bank shall maintain in accordance with its usual practice
an account or accounts evidencing indebtedness of the Borrower to such Bank
resulting from each Loan of such Bank from time to time, including the amounts
of principal and interest payable and paid to such Bank from time to time under
this Agreement.

            (c) The Administrative Agent shall maintain the Register pursuant to
subsection 10.6(d), and a subaccount therein for each Bank, in which shall be
recorded (i) the amount of each Loan made hereunder, the Type thereof and each
Interest Period applicable thereto, (ii) the amount of any principal or interest
due and payable or to become due and payable from the Borrower to each Bank
hereunder and (iii) both the amount of any sum received by the Administrative
Agent hereunder from or for the account of the Borrower and each Bank's share
thereof.

            (d) The entries made in the Register and the accounts of each Bank
maintained pursuant to Section 2.4(b) shall, to the extent permitted by
applicable law, be conclusive evidence, in the absence of manifest error, of the
existence and amounts of the obligations of the Borrower therein recorded;
provided, however, that the failure of any Bank or the Administrative Agent to
maintain the Register or any such account, or any error therein, shall not in
any manner affect the obligation of the Borrower to repay (with applicable
interest) the Loans made to such Borrower by such Bank in accordance with the
terms of this Agreement.


                                       24
<PAGE>   29
            (e) The Borrower agrees that, upon the request to the Administrative
Agent by any Bank, the Borrower will execute and deliver to such Bank a
promissory note of the Borrower evidencing the Loans of such Bank, substantially
in the form of Exhibit A with appropriate insertions as to date and principal
amount (a "Note").

             2.5 Commitment Fees. The Borrower agrees to pay to the
Administrative Agent for the account of each Bank a commitment fee for the
period from and including the Closing Date, computed at the Commitment Fee Rate
on the average daily amount of the Available Commitment of such Bank during the
period for which payment is made, payable quarterly in arrears on the last day
of each March, June, September and December and on the Termination Date,
commencing on the first of such dates to occur after the date hereof.

             2.6 Termination, Reduction or Increase of Commitments. (a) The
Borrower shall have the right, upon not less than three Business Days' notice to
the Administrative Agent (which shall give prompt notice thereof to the Banks),
to terminate the Commitments or, from time to time, to reduce the amount of the
Commitments; provided, that no such termination or reduction shall be permitted
if, after giving effect thereto and to any payments or prepayments of the Loans
made on the effective date thereof, the aggregate principal amount of the Loans
then outstanding would exceed the aggregate Commitments then in effect. Any such
reduction shall be in an amount equal to $10,000,000 or a whole multiple of
$1,000,000 in excess thereof and shall reduce permanently the Commitments then
in effect.

            (b) The Commitments shall be automatically reduced in the following
amounts at the following times by an amount equal to:

                  (i) 100% of the Net Cash Proceeds of the issuance or
incurrence of Additional Buildout Indebtedness after the Closing Date, except
for the proceeds of not more than $950,000,000 (or such higher amount as may be
approved by the Required Banks) in the aggregate of Additional Buildout
Indebtedness, net of interest accretion on non-cash pay issuances and escrowed
interest on overfunded issuances related to such Additional Buildout
Indebtedness; and

                  (ii) 100% of the Net Cash Proceeds of any sale or other
disposition by the Borrower or any of its Subsidiaries of any assets except for
sales and dispositions permitted by Section 6.5(b).

            (c) Upon the request of the Borrower to the Administrative Agent and
the Banks, the Commitments hereunder may be increased by not more than
$150,000,000 or such lesser amount as may be agreed upon by the parties as
referred to below; provided that (i) each Bank whose Commitment is increased


                                       25
<PAGE>   30
consents, (ii) the Required Banks consent, (iii) such increases are supported by
either the Lockheed Martin Guarantee or by Acceptable Letters of Credit or by
other guarantees, collateral or credit support satisfactory to the Required
Banks and (iv) if the Commitments would exceed $250,000,000 after giving effect
to such increase, Lockheed, Martin consents to such increase.

            (d) In the event of such a requested increase in the Commitments,
(i) each of the Banks shall be given the opportunity to participate in the
increased Commitments ratably in the proportions that their respective
Commitments bear to the aggregate Commitments, and (ii) to the extent that the
Banks do not elect so to participate in such increased Commitments after being
afforded an opportunity to do so, then the Borrower shall consult with the
Administrative Agent as to the number, identity and requested Commitments of
additional financial institutions which the Borrower may upon the written
consent of the Administrative Agent (which consent shall not be unreasonably
withheld) invite to participate in the Commitments.

            (e) In the event that the Borrower and one or more of the Banks (or
other financial institutions which may elect to participate) shall agree, in
accordance with Section 2.6(c), upon such an increase in the aggregate
Commitments, the Borrower, the Administrative Agent and the financial
institution in question shall enter into a Commitment Increase Supplement
setting forth the amounts of the increase in Commitments and providing that the
additional financial institutions participating shall be deemed to be included
as Banks for all purposes of this Agreement. Upon the execution and delivery of
such Commitment Increase Supplement as provided above, and upon satisfaction of
such other conditions as the Administrative Agent may specify (including the
delivery of certificates and legal opinions on behalf of the Borrower relating
to the amendment and, if applicable, new Notes), this Agreement shall be deemed
to be amended accordingly.

            (f) No Bank shall have any obligation to increase its Commitment in
the event of such a request by the Borrower hereunder.

             2.7 Prepayments. (a) The Borrower may at any time and from time to
time prepay the Loans, in whole or in part, without premium or penalty, upon at
least three Business Days' irrevocable notice to the Administrative Agent in the
case of ABR Loans and at least three Eurodollar Business Days' irrevocable
notice to the Administrative Agent in the case of Eurodollar Loans, which notice
shall specify the date and amount of prepayment and whether the prepayment is of
Eurodollar Loans, ABR Loans or a combination thereof, and, if of a combination
thereof, the amount allocable to each. Upon receipt of any such notice the
Administrative Agent shall promptly notify each Bank thereof. If any such notice
is given, the amount specified in such notice shall be due and payable on the
date specified therein, together with accrued interest to such date on the
amount prepaid.


                                       26
<PAGE>   31
Partial prepayments shall be in an aggregate principal amount of $10,000,000 or
a whole multiple of $1,000,000 in excess thereof. Each prepayment of Eurodollar
Loans shall be subject to compliance with the provisions of Sections 2.9 and
2.17.

            (b) If at any time the principal amount of Loans then outstanding
shall exceed the Commitments, the Borrower shall immediately prepay or at its
option cash collateralize the Loans as provided in Section 2.7(c) in an amount
equal to such excess. Amounts payable pursuant to this Section 2.7(b) shall be
applied, first, to prepay any ABR Loans then outstanding and second, to prepay
or cash collateralize (at the Borrower's option) any Eurodollar Loans then
outstanding (provided, that any Eurodollar Loans so cash collateralized shall be
prepaid no later than the last day of the respective Interest Periods therefor).
Each prepayment pursuant to this Section 2.7(b) shall be accompanied by accrued
interest on the amount prepaid and any amounts payable pursuant to Section 2.17.

            (c) The Borrower shall cash collateralize Eurodollar Loans pursuant
to Section 2.7(b) by depositing in an account with the Administrative Agent (the
"Eurodollar Cash Collateral Account"), to be established and maintained pursuant
to such terms and conditions as shall be specified by the Administrative Agent
in its discretion, an amount determined pursuant to the second sentence of
Section 2.7(b). Such deposited monies shall be held by the Administrative Agent
as cash collateral (the "Eurodollar Cash Collateral") for the outstanding
Eurodollar Loans on a pro rata basis; provided, that if any ABR Loans shall be
made while there is Eurodollar Cash Collateral on deposit in the Eurodollar Cash
Collateral Account, the Administrative Agent shall apply such Eurodollar Cash
Collateral to the immediate prepayment of such ABR Loans and only the Eurodollar
Cash Collateral remaining after such prepayment, if any, shall be retained in
the Eurodollar Cash Collateral Account. The Eurodollar Cash Collateral Account
and the Eurodollar Cash Collateral shall be subject to the sole dominion and
control of the Administrative Agent and, except as set forth above, the
Eurodollar Cash Collateral shall be retained in the Eurodollar Cash Collateral
Account and applied to the repayment of Eurodollar Loans on the last day of the
respective Interest Periods therefor, with the Borrower being obligated to repay
the balance of such Eurodollar Loans in the event the Eurodollar Cash Collateral
is insufficient therefor. Any amounts remaining in the Eurodollar Cash
Collateral Account after repayment of such Eurodollar Loans will be released to
the Borrower provided no Default or Event of Default exists. The Administrative
Agent shall invest the Eurodollar Cash Collateral in Cash Equivalents, and shall
pay over to the Borrower any interest earned on such investments quarterly on
the last day of each March, June, September and December; provided, that no
Default or Event of Default shall have occurred and be continuing (in which case
such interest shall be retained as Eurodollar Cash Collateral). The
Administrative Agent shall not be liable for any losses or


                                       27
<PAGE>   32
decreases in value with respect to the Eurodollar Cash Collateral, other than
those occurring as a result of its gross negligence or willful misconduct.

             2.8 Conversion and Continuation Options. (a) The Borrower may elect
from time to time to convert Eurodollar Loans to ABR Loans, by giving the
Administrative Agent at least two Business Days' prior irrevocable notice of
such election; provided, that any such conversion of Eurodollar Loans may only
be made on the last day of an Interest Period with respect thereto. The Borrower
may elect from time to time to convert ABR Loans to Eurodollar Loans by giving
the Administrative Agent at least three Eurodollar Business Days' prior
irrevocable notice of such election. Any such notice of conversion to Eurodollar
Loans shall specify the length of the initial Interest Period or Interest
Periods therefor. Upon receipt of any such notice the Administrative Agent shall
promptly notify each Bank thereof. All or any part of outstanding Eurodollar
Loans or ABR Loans may be converted as provided herein; provided, that (i) no
Loan may be converted into a Eurodollar Loan when any Event of Default (upon
notice from the Administrative Agent, on behalf of the Required Banks, except
such notice shall not be required in the case of the Event of Default described
in clause (a)(vi) of Section 8) has occurred and is continuing, (ii) any such
conversion may only be made if, after giving effect thereto, Section 2.9 shall
not have been contravened and (iii) no Loan may be converted into a Eurodollar
Loan after the date that is one month prior to the Termination Date.

            (b) Any Eurodollar Loan may be continued as such upon the expiration
of the then current Interest Period with respect thereto by the Borrower's
giving notice to the Administrative Agent, in accordance with the applicable
provisions of the term "Interest Period" set forth in Section 1.1, of the length
of the next Interest Period to be applicable to such Loans; provided, that no
Eurodollar Loan may be continued as such (i) when any Event of Default (upon
notice from the Administrative Agent, on behalf of the Required Banks, except
such notice shall not be required in the case of an Event of Default described
in clause (a)(vi) of Section 8) has occurred and is continuing, (ii) if, after
giving effect thereto, Section 2.9 would be contravened or (iii) after the date
that is one month prior to the Termination Date; provided further, that if the
Borrower shall fail to give any required notice as described above in this
paragraph or if such continuation is not permitted pursuant to the preceding
proviso such Loans shall be automatically converted to ABR Loans on the last day
of such then expiring Interest Period.

             2.9 Minimum Amounts of Tranches. All borrowings, conversions and
continuations of Loans hereunder and all selections of Interest Periods
hereunder shall be in such amounts and be made pursuant to such elections so
that, after giving effect thereto (a) the aggregate principal amount of the
Loans comprising each Tranche shall be equal to $10,000,000 or a whole


                                       28
<PAGE>   33
multiple of $1,000,000 in excess thereof and (b) there shall be no more than ten
different Tranches outstanding at any one time.

             2.10 Interest Rates and Payment Dates. (a) Each Eurodollar Loan
shall bear interest for each day during each Interest Period with respect
thereto at a rate per annum equal to the Eurodollar Rate determined for such
Interest Period plus the Applicable Margin.

            (b) Each ABR Loan shall bear interest at a rate per annum equal to
the ABR.

            (c) If all or a portion of (i) the principal amount of any Loan,
(ii) any interest payable thereon or (iii) any fee or other amount payable
pursuant to this Agreement shall not be paid when due (whether at the stated
maturity, by acceleration or otherwise), such overdue amount shall bear interest
at a rate per annum which is (y) in the case of overdue principal, the rate that
would otherwise be applicable thereto pursuant to the foregoing provisions of
this Section 2.10 plus 2% or (z) in the case of overdue interest (to the extent
permitted by applicable law), fees or other amounts, the rate described in
paragraph (b) of this Section 2.10 plus 2%, in each case from the date of such
non-payment until such amount is paid in full (whether before or, to the extent
permitted by applicable law, after judgment).

            (d) Interest shall be payable in arrears on each Interest Payment
Date; provided, that interest accruing pursuant to paragraph (c) of this Section
2.10 shall be payable on demand, or, in the absence of demand, weekly on Friday
of each week.

             2.11 Computation of Interest and Fees. (a) Interest on Loans and
fees (other than interest calculated on the basis of the Prime Rate) shall be
calculated on the basis of a 360-day year for the actual days elapsed; provided,
that interest calculated on the basis of the Prime Rate shall be calculated on
the basis of a 365- or 366- (as the case may be) day year for the actual days
elapsed. The Administrative Agent shall as soon as practicable notify in writing
the Borrower and the Banks of each determination of a Eurodollar Rate. Any
change in the interest rate on a Loan resulting from a change in the ABR shall
become effective as of the opening of business on the day on which such change
becomes effective. The Administrative Agent shall as soon as practicable notify
in writing the Borrower and the Banks of the effective date and the amount of
each such change in interest rate.

            (b) Each determination of an interest rate by the Administrative
Agent pursuant to any provision of this Agreement shall be conclusive and
binding on the Borrower and the Banks in the absence of manifest error. The
Administrative Agent shall, at the request of the Borrower or a Bank, deliver to
the Borrower or such Bank, as the case may be, a statement showing the


                                       29
<PAGE>   34
quotations used by the Administrative Agent in determining any interest rate
pursuant to Section 2.10(a).

            2.12 Inability to Determine Interest Rate. In the event that prior
to the first day of any Interest Period:

            (a) the Administrative Agent shall have determined (which
determination shall be conclusive and binding upon the Borrower) that, by reason
of circumstances affecting the relevant market, adequate and reasonable means do
not exist for ascertaining the Eurodollar Rate for such Interest Period, or

            (b) the Administrative Agent shall have received notice from the
Required Banks that the Eurodollar Rate determined or to be determined for such
Interest Period will not adequately and fairly reflect the cost to such Banks
(as conclusively certified in writing by such Banks) of making or maintaining
their affected Eurodollar Loans during such Interest Period, the Administrative
Agent shall give telecopy or telephonic notice (confirmed in writing) thereof to
the Borrower and the Banks as soon as practicable thereafter. If such notice is
given (x) any Eurodollar Loans requested to be made on the first day of such
Interest Period shall be made as ABR Loans, (y) any Loans that were to have been
converted on the first day of such Interest Period to Eurodollar Loans shall be
continued as ABR Loans and (z) any outstanding Eurodollar Loans shall be
converted, on the first day of such Interest Period, to ABR Loans. The
Administrative Agent shall promptly notify the Borrower at such time as the
conditions set forth in (a) and (b) above are no longer in effect, and until
such notice has been delivered by the Administrative Agent, no further
Eurodollar Loans shall be made or continued as such, nor shall the Borrower have
the right to convert Loans to Eurodollar Loans.

             2.13 Pro Rata Treatment and Payments. (a) Each borrowing by the
Borrower from the Banks of Loans, each payment by the Borrower on account of any
commitment fee hereunder and any reduction of the Commitments of the Banks shall
be made pro rata according to the respective Commitment Percentages of the
Banks. Each payment (including each prepayment) by the Borrower on account of
principal of and interest on the Loans shall be made pro rata according to the
respective outstanding principal amounts of the Loans then held by the Banks
except to the extent any other provision of this Agreement provides for non pro
rata payments. All payments (including prepayments) to be made by the Borrower
hereunder and under the Notes, whether on account of principal, interest, fees
or otherwise, shall be made without set-off or counterclaim and shall be made
prior to 12:00 Noon, New York City time, on the due date thereof to the
Administrative Agent, for the account of the Banks, at the Administrative
Agent's office specified in Section 10.2, in Dollars and in immediately
available funds. The Administrative Agent shall distribute such payments to the
Banks promptly upon receipt in like funds as received. If any payment hereunder
(other than


                                       30
<PAGE>   35
payments on the Eurodollar Loans) becomes due and payable on a day other than a
Business Day, such payment shall be extended to the next succeeding Business
Day, and, with respect to payments of principal, interest thereon shall be
payable at the then applicable rate during such extension. If any payment on a
Eurodollar Loan becomes due and payable on a day other than a Eurodollar
Business Day, the maturity thereof shall be extended to the next succeeding
Eurodollar Business Day unless the result of such extension would be to extend
such payment into another calendar month, in which event such payment shall be
made on the immediately preceding Eurodollar Business Day.

            (b) Unless the Administrative Agent shall have been notified in
writing by any Bank prior to a Borrowing Date that such Bank will not make the
amount that would constitute its portion of the borrowing to be made on such
date available to the Administrative Agent, the Administrative Agent may assume
that such Bank has made such amount available to the Administrative Agent on
such Borrowing Date, and the Administrative Agent may, in reliance upon such
assumption, make available to the Borrower a corresponding amount. If such
amount is made available to the Administrative Agent on a date after such
Borrowing Date, such Bank shall pay to the Administrative Agent on demand an
amount equal to the product of (i) the daily average Federal funds rate during
such period as quoted by the Administrative Agent, times (ii) the amount of such
Bank's portion of such borrowing, times (iii) a fraction the numerator of which
is the number of days that elapse from and including such Borrowing Date to the
date on which such Bank's portion of such borrowing shall have become
immediately available to the Administrative Agent and the denominator of which
is 360. A certificate of the Administrative Agent submitted to any Bank with
respect to any amounts owing under this Section 2.13(b) shall be conclusive in
the absence of manifest error. If such Bank's portion of such borrowing is not
in fact made available to the Administrative Agent by such Bank within three
Business Days of such Borrowing Date, the Administrative Agent shall be entitled
to recover such amount with interest thereon at the rate per annum applicable to
ABR Loans hereunder, on demand, from the Borrower. If the Borrower returns to
the Administrative Agent any amount with interest thereon as described in the
immediately preceding sentence, such Bank shall indemnify the Borrower for the
difference, if any, between (i) the aggregate interest paid by the Borrower to
the Administrative Agent in accordance with the immediately preceding sentence
less (ii) the aggregate interest which actually accrued on such amount prior to
its return to the Administrative Agent.

             2.14 Illegality. Notwithstanding any other provision herein, if any
change in any Requirement of Law or in the interpretation or application thereof
shall make it unlawful for any Bank to make or maintain Eurodollar Loans as
contemplated by this Agreement, (a) the commitment of such Bank hereunder to
make Eurodollar Loans, continue Eurodollar Loans as such and convert ABR Loans
to Eurodollar Loans shall forthwith be cancelled and


                                       31
<PAGE>   36
(b) such Bank's Loans then outstanding as Eurodollar Loans, if any, shall be
converted automatically to ABR Loans on the respective last days of the then
current Interest Periods with respect to such Loans or within such earlier
period as required by law. If any such conversion of a Eurodollar Loan occurs on
a day which is not the last day of the then current Interest Period with respect
thereto, the Borrower shall pay to such Bank such amounts, if any, as may be
required pursuant to Section 2.17.

             2.15 Other Costs; Increased Costs. (a) The Borrower agrees to pay
to each Bank which requests compensation under this Section 2.15(a) (by written
notice to the Borrower through the Administrative Agent), on the last day of
each Interest Period with respect to any Eurodollar Loan made by such Bank, so
long as such Bank shall be required to maintain reserves against "Eurocurrency
liabilities" under Regulation D of the Board of Governors of the Federal Reserve
System (or, so long as such Bank may be required by such Board of Governors or
by any other Governmental Authority to maintain reserves against any category of
liabilities which includes deposits by reference to which the interest rate on
Eurodollar Loans is determined as provided in this Agreement or against any
category of extensions of credit or other assets of such Bank which includes any
Eurodollar Loans), an additional amount (determined by such Bank and promptly
notified to the Borrower) representing such Bank's calculation or, if an
accurate calculation is impracticable, reasonable estimate (using such
reasonable means of allocation as such Bank shall determine) of the actual
costs, if any, incurred by such Bank while such Eurodollar Loans were
outstanding as a result of the applicability of the foregoing reserves to such
Eurodollar Loans, which amount in any event shall not exceed the product of the
following for each day while such Eurodollar Loans were outstanding:

                  (i) the principal amount of the relevant Eurodollar Loans made
by such Bank outstanding on such day; and

                  (ii) the difference between (x) a fraction the numerator of
which is the Eurodollar Rate (expressed as a decimal) applicable to such
Eurodollar Loans, and the denominator of which is one minus the maximum rate
(expressed as a decimal) at which such reserve requirements are imposed by such
Board of Governors or other Governmental Authority on such date minus (y) such
numerator; and

                  (iii) a fraction the numerator of which is one and the
denominator of which is 360.

            (b) In the event that any change in any Requirement of Law or in the
interpretation or application thereof or compliance by any Bank with any request
or directive (whether or not having the force of law) from any central bank or
other Governmental Authority made subsequent to the date hereof:


                                       32
<PAGE>   37
                  (i) shall subject any Bank to any tax of any kind whatsoever
with respect to this Agreement, any Note or any Eurodollar Loan made by it, or
change the basis of taxation of payments to such Bank in respect thereof (except
for taxes covered by Section 2.16 and changes in the rate of tax on the overall
net income of such Bank);

                  (ii) shall impose, modify or hold applicable any reserve,
special deposit, compulsory loan or similar requirement against assets held by,
deposits or other liabilities in or for the account of, advances, loans or other
extensions of credit by, or any other acquisition of funds by, any office of
such Bank which is not otherwise described in Section 2.15(a); or

                  (iii) shall impose on such Bank any other condition;

and the result of any of the foregoing is to increase the cost to such Bank, by
an amount which such Bank deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans or to reduce any amount receivable
hereunder in respect thereof, then the Borrower shall pay such Bank within 15
Business Days following demand therefor any additional amounts necessary to
compensate such Bank for such increased cost or reduced amount receivable. If
any Bank becomes entitled to claim any additional amounts pursuant to this
Section 2.15(b), it shall promptly notify the Borrower, through the
Administrative Agent, of the event by reason of which it has become so entitled.

            (c) In the event that any Bank shall have determined that any change
in any Requirement of Law regarding capital adequacy or in the interpretation or
application thereof or compliance by such Bank or any corporation controlling
such Bank with any request or directive regarding capital adequacy (whether or
not having the force of law) from any Governmental Authority made subsequent to
the date hereof does or shall have the effect of reducing the rate of return on
such Bank's or such corporation's capital as a consequence of its obligations
hereunder to a level below that which such Bank or such corporation could have
achieved but for such change or compliance (taking into consideration such
Bank's or such corporation's policies with respect to capital adequacy) by an
amount deemed by such Bank to be material, then from time to time, after prompt
submission by such Bank to the Borrower (with a copy to the Administrative
Agent) of a written request therefor, the Borrower shall pay to such Bank within
15 Business Days following demand therefor such additional amount or amounts as
will compensate such Bank or such corporation for such reduction.

            (d) A certificate as to any additional amounts payable pursuant to
this Section 2.15 submitted by the relevant Bank, through the Administrative
Agent, to the Borrower shall be conclusive in the absence of manifest error. The
covenants contained in this Section 2.15 shall survive the termination of


                                       33
<PAGE>   38
this Agreement and the payment of the Notes and all other amounts payable
hereunder. Any notice to be given by a Bank under this Section 2.15 after
termination of this Agreement shall be effective only if given within 120 days
after such Bank becomes aware or should have become aware of the events giving
rise to such notice.

             2.16 Taxes. (a) All payments made by the Borrower under this
Agreement and the Notes shall be made free and clear of, and without deduction
or withholding for or on account of, any present or future income, stamp or
other taxes, levies, imposts, duties, charges, fees, deductions or withholdings
imposed, levied, collected, withheld or assessed by any Governmental Authority,
excluding, in the case of the Administrative Agent and each Bank, (i) net income
taxes, franchise and branch profit taxes (imposed in lieu of net income taxes)
imposed on the Administrative Agent or such Bank, as the case may be, as a
result of a present or former connection between the jurisdiction of the
government or taxing authority imposing such tax and the Administrative Agent or
such Bank (excluding a connection arising solely from the Administrative Agent
or such Bank having executed, delivered or performed its obligations or received
a payment under, or enforced, this Agreement or the Notes) or any political
subdivision or taxing authority thereof or therein, (ii) any taxes, levies,
imposts, duties, charges, fees, deductions or withholdings arising after the
Closing Date, solely as a result of or attributable to the Administrative Agent
or Bank (x) changing its designated lending office as of the Closing Date to a
lending office located in any other jurisdiction or (y) designating an
additional lending office located in any other jurisdiction and (iii) any taxes,
levies, imposts, duties, charges, fees, deductions or withholdings in effect on
the Closing Date (all such non-excluded taxes, levies, imposts, duties, charges,
fees, deductions and withholdings being hereinafter called "Taxes"). If any
Taxes are required to be withheld from any amounts payable to the Administrative
Agent or any Bank hereunder or under the Notes, the amounts so payable to the
Administrative Agent or such Bank shall be increased to the extent necessary to
yield to the Administrative Agent or such Bank (after payment of all Taxes)
interest or any such other amounts payable hereunder at the rates or in the
amounts specified in this Agreement and the Notes. Whenever any Taxes are
payable by the Borrower, as promptly as possible thereafter the Borrower shall
send to the Administrative Agent for its own account or for the account of the
Administrative Agent or such Bank, as the case may be, a copy of any original
official receipt that may be received by the Borrower showing payment thereof.
If the Borrower fails to pay any Taxes when due to the appropriate taxing
authority or fails to remit to the Administrative Agent the receipts that may be
received or other available documentary evidence, the Borrower shall indemnify
the Administrative Agent and the Banks for any incremental taxes, interest or
penalties that may become payable by the Administrative Agent or any Bank to the
United States or


                                       34
<PAGE>   39
other Governmental Authority as a result of any such failure. The agreements in
this Section 2.16(a) shall survive the termination of this Agreement and the
payment of the Notes and all other amounts payable hereunder. If any Taxes
constituting a withholding tax of the United States of America or any other
Governmental Authority shall be or become applicable, after the Closing Date, to
such payments by the Borrower to the Administrative Agent or Bank, the
Administrative Agent or such Bank shall use its best efforts to make, fund and
maintain its Loans through another lending office of the Administrative Agent or
such Bank in another jurisdiction so as to reduce, to the fullest extent
possible, the Borrower's liability hereunder, if the making, funding or
maintenance of such Loans through such other office does not otherwise
materially adversely affect such Loans or the Administrative Agent or such Bank.

            (b) Prior to the first Interest Payment Date, each Bank that is not
incorporated under the laws of the United States of America or a state thereof
agrees that it will deliver to the Borrower and the Administrative Agent (i) two
duly completed copies of United States Internal Revenue Service Form 1001 or
4224 or successor applicable form, as the case may be, and (ii) an Internal
Revenue Service Form W-8 or W-9 or successor applicable form. Each such Bank
also agrees to deliver to the Borrower and the Administrative Agent two further
copies of the said Form 1001 or 4224 and Form W-8 or W-9, or successor
applicable forms or other manner of certification, as the case may be, on or
before the date that any such form expires or becomes obsolete or after the
occurrence of any event requiring a change in the most recent form previously
delivered by it to the Borrower, and such extensions or renewals thereof as may
reasonably be requested by the Borrower or the Administrative Agent, unless in
any such case an event (including, without limitation, any change in treaty, law
or regulation) has occurred prior to the date on which any such delivery would
otherwise be required which renders all such forms inapplicable or which would
prevent such Bank from duly completing and delivering any such form with respect
to it and such Bank so advises the Borrower and the Administrative Agent. Such
Bank shall certify (i) in the case of a Form 1001 or 4224, that it is entitled
to receive payments under this Agreement without deduction or withholding of any
United States federal income taxes and (ii) in the case of a Form W-8 or W-9,
that it is entitled to an exemption from United States backup withholding tax.
The Borrower shall not be required to pay any increased amount on account of
Taxes pursuant to this Section 2.16 to the Administrative Agent or any Bank that
fails to furnish any form or statement that it is required to furnish in
accordance with this Section 2.16(b) and, to the extent required by law, the
Borrower shall be entitled to deduct Taxes from the payments owed to such Bank
or the Administrative Agent. In the event that the Borrower is required to pay
any Bank any additional amount or indemnify any Bank pursuant to Section 2.16(a)
(subject to the provisions of Section 2.17) and no change in lending office is
made in accordance with the last


                                       35
<PAGE>   40
sentence of Section 2.16(a), after the Borrower makes such payment, such Bank
shall transfer, in accordance with the procedures set forth in Section 11.6(c),
its Loans and Commitment to a Bank selected by the Borrower with the approval of
such transferor Bank and the Administrative Agent (not to be unreasonably
withheld).

             2.17 Indemnity. The Borrower agrees to indemnify each Bank and to
hold each Bank harmless from any loss or expense which such Bank may sustain or
incur as a consequence of (a) default by the Borrower in payment when due of the
principal amount of or interest on any Eurodollar Loan, (b) default by the
Borrower in making a borrowing of, conversion into or continuation of Eurodollar
Loans after the Borrower has given a notice requesting the same in accordance
with the provisions of this Agreement, (c) default by the Borrower in making any
prepayment after the Borrower has given a notice thereof in accordance with the
provisions of this Agreement, (d) the making of a voluntary or involuntary
prepayment of Eurodollar Loans on a day which is not the last day of an Interest
Period with respect thereto or (e) the conversion of Eurodollar Loans to ABR
Loans pursuant to Section 2.12 or 2.14 on a day which is not the last day of the
Interest Period with respect thereto, including, without limitation, in each
case, any such loss or expense arising from the reemployment of funds obtained
by it or from fees payable to terminate the deposits from which such funds were
obtained. A certificate setting forth the computation of any amount payable
pursuant to the foregoing sentence submitted by a Bank, through the
Administrative Agent, to the Borrower shall be conclusive in the absence of
manifest error. This covenant shall survive the termination of this Agreement
and the payment of the Notes and all other amounts payable hereunder.

             2.18 Purpose. The proceeds of the Loans shall be used by the
Borrower solely to finance (i) the buildout of the Satellite Project and (ii)
interest payments on the Loans and (iii) working capital needs.

            SECTION 3. REPRESENTATIONS AND WARRANTIES

            In order to induce the Banks to enter into this Agreement and to
make the Loans herein provided for, the Borrower hereby represents and warrants
to the Administrative Agent and to each Bank that:

            3.1 Financial Condition. (a) The consolidated balance sheet of the
Borrower as at December 31, 1994 and the related consolidated statements of
operations, of partners' capital and of cash flows for the fiscal period ended
on such date, reported on by Deloitte & Touche and (b) the unaudited
consolidated balance sheet of the Borrower as at September 30, 1995 and the
related unaudited consolidated statements of operations and of cash flows for
the fiscal quarter ended on such date, copies of which have heretofore been
furnished to each


                                       36
<PAGE>   41
Bank, are complete and correct in all material respects and present fairly
(except, with respect to interim reports, for normal year-end adjustments) the
consolidated financial condition of the Borrower as at such date, and the
consolidated results of their operations and cash flows for the fiscal period
then ended. All such financial statements, including the related schedules and
notes thereto, have been prepared in accordance with GAAP applied consistently
throughout the periods involved (except as approved by such accountants and as
disclosed therein). Such financial statements, taken together, disclose, in
accordance with GAAP, all material contingent liabilities and liability for
taxes, long-term leases and unusual forward or long-term commitments of the
Borrower and its Subsidiaries.

             3.2 No Change. Since December 31, 1994 (a) there has been no change
in the business, operations, property or financial or other condition of the
Borrower or any of its Subsidiaries which has or could reasonably be expected to
have a Material Adverse Effect, and (b) no dividends or distributions have been
declared, paid or made upon any Equity Interests of the Borrower nor have any
shares or other units of Equity Interests of the Borrower been redeemed,
retired, purchased or otherwise acquired for value by the Borrower or any of its
Subsidiaries except as permitted by Section 6.6.

             3.3 Existence; Compliance with Law. Each of the Borrower and its
Subsidiaries (a) is duly organized, validly existing and in good standing under
the laws of the jurisdiction of its incorporation or organization, (b) has the
partnership or corporate power and authority and the legal right to own and
operate its property, to lease the property it operates as lessee and to conduct
the business in which it is currently engaged, (c) is duly qualified as a
foreign partnership or corporation, as the case may be, and in good standing
under the laws of each jurisdiction where its ownership, lease or operation of
property or the conduct of its business requires such qualification, except to
the extent that the failure to be so qualified could not, in the aggregate,
reasonably be expected to have a Material Adverse Effect, and (d) is in
compliance with all Requirements of Law except to the extent that the failure to
comply therewith could not, in the aggregate, reasonably be expected to have a
Material Adverse Effect.

             3.4 Power; Authorization; Enforceable Obligations. Each of the
Borrower and its Subsidiaries has the partnership or corporate, as the case may
be, power and authority and the legal right to make, deliver and perform the
Loan Documents to which it is a party and, in the case of the Borrower, to
borrow hereunder and has taken all necessary partnership or corporate action to
authorize the execution, delivery and performance of the Loan Documents to which
it is a party and, in the case of the Borrower, the borrowings hereunder on the
terms and conditions of this Agreement. No consent or authorization of, filing
with or other act by or in respect of any Governmental Authority is


                                       37
<PAGE>   42
required in connection with the borrowings hereunder or with the execution,
delivery, performance, validity or enforceability of the Loan Documents, other
than those which have been obtained or made and are in full force and effect,
including, but not limited to, the license granted on January 31, 1995 by the
Federal Communications Commission authorizing the construction, launch and
operation of the Satellite Project in the United States, provided that this
sentence shall not apply to the Feeder Link Licenses. This Agreement has been,
and each other Loan Document will be, duly executed and delivered on behalf of
each Loan Party (other than Lockheed Martin) party thereto. This Agreement
constitutes and each other Loan Document (other than the Lockheed Martin
Guarantee), when executed and delivered will constitute, a legal, valid and
binding obligation of each Loan Party thereto enforceable against such Loan
Party in accordance with its terms, except as enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or similar laws
affecting the enforcement of creditors' rights generally and by general
equitable principles (whether enforcement is sought by proceedings in equity or
at law).

             3.5 No Legal Bar. The execution, delivery and performance of the
Loan Documents to which the Borrower or a Subsidiary is a party, the borrowings
hereunder and the use of the proceeds thereof, will not violate any Requirement
of Law or any Contractual Obligation applicable to the Borrower or of any of the
Subsidiaries, and will not result in, or require, the creation or imposition of
any Lien on any of its or their respective properties or revenues pursuant to
any Requirement of Law or Contractual Obligation.

             3.6 No Material Litigation. No litigation, investigation or
proceeding of or before any arbitrator or Governmental Authority is pending or,
to the knowledge of the Borrower, threatened by or against the Borrower or any
of the Subsidiaries or against any of its or their respective properties or
revenues (a) with respect to any of the Loan Documents or any of the
transactions contemplated hereby or thereby, or (b) which could reasonably be
expected to have a Material Adverse Effect.

             3.7 No Default. Neither the Borrower nor any of the Subsidiaries is
in default under or with respect to any Contractual Obligation in any respect
which could reasonably be expected to have a Material Adverse Effect. No Default
or Event of Default has occurred and is continuing.

             3.8 Ownership of Property; Liens. Each of the Borrower and the
Subsidiaries has good record and marketable title in fee simple to or valid
leasehold interests in all its real property, and good title to all its other
property, and none of such property is subject to any Lien, except as permitted
in Section 7.3 and except where the failure to have such title could not, in the
aggregate, reasonably be expected to have a Material Adverse Effect.

             3.9 Intellectual Property. The Borrower and each of its
Subsidiaries owns, or are licensed to use, all trademarks, tradenames,
copyrights, technology, know-how and processes (the "Intellectual Property"),
necessary for the conduct of its business as currently contemplated except for
those the failure to own or license which could not reasonably be expected to
have a Material Adverse Effect. No claim has been asserted and is pending by any
Person challenging or questioning the use of any such Intellectual Property or
the validity or effectiveness of any such Intellectual Property, nor does the
Borrower know of any valid basis for any such claim. The use of such
Intellectual Property by the Borrower and its Subsidiaries does not infringe on
the rights of any Person, except for such claims and infringements that, in the
aggregate, could not reasonably be expected to have a Material Adverse Effect.

             3.10  No Burdensome Restrictions.  No Requirement of Law or
Contractual Obligation of the Borrower or any of its Subsidiaries could
reasonably be expected to have a Material Adverse Effect.

             3.11 Taxes. Each of the Borrower and the Subsidiaries has filed or
caused to be filed all tax returns which to the knowledge of the Borrower are
required to be filed and has paid all taxes shown to be due and payable on said
returns or on any assessments made against it or any of its property and all
other taxes, fees or other charges imposed on it or any of its property by any
Governmental Authority (other than those the amount or validity of which is
currently being contested in good faith by appropriate proceedings and with
respect to which reserves in conformity with GAAP have been provided on the
books of the Borrower or the Subsidiaries, as the case may be, and other than
those the non-payment of which could not, in the aggregate, reasonably be
expected to have a Material Adverse Effect); and no federal income tax liens
have been filed and, to the knowledge of the Borrower, no claims are being
asserted with respect to any such taxes, fees or other charges, except any such
claims which could not reasonably be expected to have a Material Adverse Effect.

             3.12 Federal Regulations. No part of the proceeds of any Loans
hereunder will be used for the purpose of "purchasing" or "carrying" any "margin
stock" within the respective meanings of each of the quoted terms under
Regulation U of the Board of Governors of the Federal Reserve System as now and
from time to time hereafter in effect or for any purpose which violates the
provisions of the Regulations of such Board of Governors. If requested by any
Bank or the Administrative Agent, the Borrower will furnish to the
Administrative Agent and each Bank a statement to the foregoing effect in
conformity with the requirements of Federal Reserve Form U-1 referred to in said
Regulation U.

             3.13 ERISA. Neither a Reportable Event nor an "accumulated funding
deficiency" (within the meaning of Section 412 of the Code or Section 302 of
ERISA) has occurred during the five-year period prior to the date on which this
representation is made or deemed made with respect to any Plan which has
resulted or could reasonably be expected to result in a liability to the
Borrower or any Subsidiary in excess of $1,000,000, and each Plan has complied
in all material respects with the applicable provisions of ERISA and the Code.
No termination of a Single Employer Plan has occurred, and no Lien in favor of
the PBGC or a Plan has arisen, during such five-year period. The present value
of all accrued benefits under each Single Employer Plan (based on those
assumptions used to fund such Plans) did not, as of the last annual valuation
date prior to the date on which this representation is made or deemed made,
exceed, by more than $5,000,000, the value of the assets of such Plan allocable
to such accrued benefits. Neither the Borrower nor any Commonly Controlled
Entity has had a complete or partial withdrawal from any Multiemployer Plan, and
neither the Borrower nor any Commonly Controlled Entity would become subject to
any liability under ERISA if the Borrower or any such Commonly Controlled Entity
were to withdraw completely from all Multiemployer Plans as of the valuation
date most closely preceding the date on which this representation is made or
deemed made, where such liability could, in the aggregate, reasonably be
expected to have a Material Adverse Effect. No such Multiemployer Plan is in
Reorganization or Insolvent.

             3.14 Investment Company Act; Other Regulations. The Borrower is not
an "investment company", or a company "controlled" by an "investment company",
within the meaning of the Investment Company Act of 1940, as amended. The
Borrower is not subject to regulation under any Federal or State statute or
regulation which limits its ability to incur Indebtedness.

             3.15 Subsidiaries. The Borrower has no Subsidiaries other than
Foreign Subsidiaries and other than Subsidiaries which are Guarantors.

             3.16 Environmental Matters. Each of the representations and
warranties set forth in paragraphs (a) through (e) of this Section 3.16 is true
and correct with respect to each parcel of real property owned or operated by
the Borrower or any Subsidiary (the "Properties"), except to the extent that (i)
the facts and circumstances giving rise to such failure to be so true and
correct could not reasonably be expected to have a Material Adverse Effect or
(ii) the Borrower and the Subsidiaries are fully indemnified against any
liabilities which may result from any such failure to be so true and correct:

            (a) The Properties do not contain, and have not previously
contained, in, on, or under, including, without limitation, the soil and
groundwater thereunder, any Hazardous Materials in concentrations which violate
Environmental Laws.


                                       40
<PAGE>   45
            (b) The Properties and all operations and facilities at the
Properties are in compliance with all Environmental Laws, and there is no
Hazardous Materials contamination or violation of any Environmental Law which
could interfere with the continued operation of any of the Properties or impair
the fair saleable value of any thereof.

            (c) Neither the Borrower nor any of the Subsidiaries has received
any written complaint, notice of violation, alleged violation, investigation or
advisory action or of potential liability or of potential responsibility
regarding environmental protection matters or permit compliance with regard to
the Properties, nor is the Borrower aware that any Governmental Authority is
threatening to deliver to the Borrower or any of the Subsidiaries any such
notice.

            (d) Hazardous Materials have not been generated, treated, stored,
disposed of, at, on or under any of the Properties, nor have any Hazardous
Materials been transferred from the Properties to any other location in
violation of any Environmental Law.

            (e) There are no governmental, administrative actions or judicial
proceedings pending or (to the knowledge of the Borrower) contemplated under any
Environmental Laws to which the Borrower or any of the Subsidiaries is or (to
the knowledge of the Borrower) will be named as a party with respect to the
Properties, nor are there any consent decrees or other decrees, consent orders,
administrative orders or other orders, or other administrative or judicial
requirements outstanding under any Environmental Law with respect to any of the
Properties.

             3.17 Full Disclosure. All information (other than projections)
heretofore furnished by or on behalf of the Borrower to the Administrative Agent
or any Bank for purposes of or in connection with this Agreement or any
transaction contemplated hereby is, and all such information hereafter furnished
by or on behalf of the Borrower to the Administrative Agent or any Bank will be,
true and accurate in all material respects on the date as of which such
information is stated or certified. All projections heretofore furnished by or
on behalf of the Borrower to the Administrative Agent or any Bank for purposes
of or in connection with this Agreement or any transaction contemplated hereby
is, and all such projections hereafter furnished by or on behalf of the Borrower
to the Administrative Agent or any Bank will be, prepared in good faith based
upon reasonable assumptions. The Borrower has disclosed to the Banks in writing
any and all facts which could reasonably be expected to have a Material Adverse
Effect.

             3.18 Solvency. (a) Immediately following the making of each Loan
made on the Closing Date and after giving effect to the application of the
proceeds thereof, the Borrower will be


                                       41
<PAGE>   46
solvent, as defined under applicable creditors' rights and fraudulent conveyance
laws.

            (b) The Borrower does not intend to, and does not believe that it or
any Subsidiary will, incur debts beyond its ability to pay such debts as they
mature, taking into account the timing and amounts of cash to be received by it
or any such Subsidiary and the timing and amounts of cash to be payable on or in
respect of its Indebtedness or the Indebtedness of any such Subsidiary.

             3.19 Security Interests; Guarantees. All Obligations (and, if
applicable, the obligations of a Subsidiary under any guarantee referred to in
the last sentence of this Section ) are secured on at least a pari passu and
equal and ratable basis by all collateral securing all outstanding Additional
Buildout Indebtedness. The Security Documents are effective to create a
perfected security interest in, and enforceable Lien on, all such collateral to
the extent permitted under applicable law for the benefit of the Administrative
Agent and the Banks. Insofar as any of such outstanding Additional Buildout
Indebtedness is owed by or guaranteed by a Subsidiary of the Borrower, such
Subsidiary has guaranteed payment of the Obligations.

            Notwithstanding the foregoing, the representations and warranties
set forth in clause (a) of Section 3.2 and in this Section 3.19 shall not be
required to be made prior to the Release Date and shall be deemed to be made on
the Release Date and on each Borrowing Date thereafter.

                  (ix) An Event of Default under Section 11 of the Lockheed
Martin Guarantee shall occur.

            (b) From and After the Release Date:

                  (i) Any of the events described in the preceding paragraph (a)
shall have occurred other than (A) any of such events described in paragraph
(a)(ii) relating to Lockheed Martin or (B) an event described in paragraph
(a)(vii) or (a)(ix); or

                  (ii) The Borrower or any of its Subsidiaries shall (A) default

principal amount of (x) all such Indebtedness equals or exceeds $1,000,000 or
(y) all such Contingent Obligations equal or exceed $5,000,000 and (II) the
effect of such default is to cause, or permit the holder or holders of such
Indebtedness or beneficiary or beneficiaries of such Contingent Obligation (or a
trustee or agent on behalf of such holder or holders or beneficiary or
beneficiaries) to cause, with the giving of notice if required, such
Indebtedness to become due prior to its stated maturity or such Contingent
Obligation to become payable or (B) default in the observance or performance of
any other agreement or condition relating to any such Indebtedness or such

transaction" (as defined in Section 406 of ERISA or Section 4975 of the Code)
involving any Plan, (B) any "accumulated funding deficiency" (as defined in

Plan, (C) a Reportable Event shall occur with respect to, or proceedings shall
commence to have a trustee appointed, or a trustee shall be appointed, to
administer or to terminate, any Single Employer Plan, which Reportable Event or
commencement of proceedings or appointment of a trustee is, in the reasonable
opinion of the Required Banks, likely to result in the


                                       60
<PAGE>   65
termination of such Plan for purposes of Title IV of ERISA, (D) any Single

or any Commonly Controlled Entity shall, or is, in the reasonable opinion of the
Required Banks, likely to, incur any liability in connection with a withdrawal
from, or the Insolvency or Reorganization of, a Multiemployer Plan, or (F) any
other event or condition shall occur or exist with respect to a Plan; and in
each case in clauses (A) through (F) above, such event or condition, together
with all other such events or conditions, if any, could subject the Borrower or
any of its Subsidiaries to any tax, penalty or other liabilities in the
aggregate material in relation to the business, operations, property or
financial or other condition of the Borrower and its Subsidiaries taken as a
whole; or

                  (iv) One or more judgments or decrees shall be entered against

operation of their business or for the construction, completion and operation of
the Satellite Project; or

                  (vi) (A) Any of the Security Documents shall cease, for any
reason, to be in full force and effect, or the Borrower or any other Loan Party
which is a party to any of the Security Documents shall so assert or (B) the
Lien created by any of the Security Documents shall cease to be enforceable and
of the same effect and priority purported to be created thereby or (C) on and
after the Release Date the representation and warranty contained in Section 3.19
shall not be true.

then, and in any such event, (A) if such event is an Event of Default specified
in paragraph (a)(vi) above, both prior to and after the Release Date,
automatically the Commitments shall immediately terminate and the Loans
hereunder (with accrued interest thereon) and all other amounts owing under this
Agreement and the Notes shall immediately become due and payable, and (B) if
such event is any other Event of Default, either or both of the following
actions may be taken, without prejudice to the rights of any Bank to enforce its
claims against the Borrower: (i) with the consent of the Majority Banks, the
Administrative Agent may, or upon the request of the Majority Banks, the
Administrative Agent


                                       61
<PAGE>   66
shall, by notice to the Borrower, declare the Commitments to be terminated
forthwith, whereupon the Commitments shall immediately terminate; and (ii) with
the consent of the Majority Banks, the Administrative Agent may, or upon the
request of the Majority Banks, the Administrative Agent shall, by notice of
default to the Borrower, declare the Loans hereunder (with accrued interest
thereon) and all other amounts owing under this Agreement and the Notes to be
due and payable forthwith, whereupon the same shall immediately become due and
payable. Except as expressly provided above in this Section 8, presentment,
demand, protest and all other notices of any kind are hereby expressly waived.

            SECTION 9. THE ADMINISTRATIVE AGENT

             9.1 Appointment. Each Bank hereby irrevocably designates and
appoints Chemical as the Administrative Agent of such Bank under this Agreement
and the other Loan Documents, and each such Bank irrevocably authorizes
Chemical, as the Administrative Agent for such Bank, to take such action on its
behalf under the provisions of this Agreement and the other Loan Documents, and
to exercise such powers and perform such duties as are expressly delegated to
the Administrative Agent by the terms of this Agreement and the other Loan
Documents, together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere in this Agreement and
the other Loan Documents, the Administrative Agent shall not have any duties or
responsibilities, except those expressly set forth herein, or any fiduciary
relationship with any Bank, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or otherwise exist against the Administrative Agent.

             9.2 Delegation of Duties. The Administrative Agent may execute any
of its duties under this Agreement and the other Loan Documents by or through
agents or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties. The Administrative Agent shall
not be responsible for the negligence or misconduct of any agents or
attorneys-in-fact selected by any of them with reasonable care.

             9.3 Exculpatory Provisions. Neither the Administrative Agent nor
any of its officers, directors, employees, agents, attorneys-in-fact or
affiliates shall be (i) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement and the
other Loan Documents (except for its or such Person's own gross negligence or
willful misconduct), or (ii) responsible in any manner to any of the Banks for
any recitals, statements, representations or warranties made by any Loan Party
or any officer thereof contained in this Agreement or in the other Loan
Documents or in any certificate, report, statement or other document referred to
or provided for in, or received by the Administrative Agent under or in
connection with, the Loan Documents or for the value, validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Loan
Document or for any failure of any Loan Party to perform its obligations
hereunder or thereunder. The Administrative Agent shall not be under any
obligation to any Bank to ascertain or to


                                       62
<PAGE>   67
inquire as to the observance or performance of any of the agreements contained
in, or conditions of, any Loan Document, or to inspect the properties, books or
records of any Loan Party.

             9.4 Reliance by the Administrative Agent. The Administrative Agent
shall be entitled to rely, and shall be fully protected in relying, upon any
Note, writing, resolution, notice, consent, certificate, affidavit, letter,
cablegram, telegram, telecopy, telex or teletype message, statement, order or
other document or conversation believed by it to be genuine and correct and to
have been signed, sent or made by the proper Person or Persons and upon advice
and statements of legal counsel (including, without limitation, counsel to the
Loan Parties), independent accountants and other experts selected by the
Administrative Agent. The Administrative Agent may deem and treat the payee of
any Note as the owner thereof for all purposes unless a written notice of
assignment, negotiation or transfer thereof shall have been filed with the
Administrative Agent. The Administrative Agent shall be fully justified in
failing or refusing to take any action under this Agreement unless it shall
first receive such advice or concurrence of the Majority Banks or the Required
Banks, as the case may be, as it deems appropriate or it shall first be
indemnified to its satisfaction by the Banks against any and all liability and
expense which may be incurred by it by reason of taking or continuing to take
any such action. The Administrative Agent shall in all cases be fully protected
in acting, or in refraining from acting, under this Agreement and the other Loan
Documents in accordance with a request of the Majority Banks or the Required
Banks, as the case may be, and such request and any action taken or failure to
act pursuant thereto shall be binding upon all the Banks and all future holders
of the Notes.

             9.5 Notice of Default. The Administrative Agent shall not be deemed
to have knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless the Administrative Agent has received notice from a Bank or the
Borrower referring to this Agreement, describing such Default or Event of
Default and stating that such notice is a "notice of default". In the event that
the Administrative Agent receives such a notice, the Administrative Agent shall
give notice thereof to the Banks. The Administrative Agent shall take such
action with respect to such Default or Event of Default as shall be reasonably
directed by the Majority Banks; provided, that unless and until the
Administrative Agent shall have received such directions, the Administrative
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default or Event of Default as it shall
deem advisable in the best interests of the Banks.

             9.6 Non-Reliance on the Administrative Agent and Other Banks. Each
Bank expressly acknowledges that neither the Administrative Agent nor any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates has made
any


                                       63
<PAGE>   68
representations or warranties to it and that no act by the Administrative Agent
hereafter taken, including any review of the affairs of any Loan Party, shall be
deemed to constitute any representation or warranty by the Administrative Agent
to any Bank. Each Bank represents to the Administrative Agent that it has,
independently and without reliance upon the Administrative Agent or any other
Bank, and based on such documents and information as it has deemed appropriate,
made its own appraisal of and investigation into the business, operations,
property, financial and other condition and creditworthiness of each Loan Party,
and made its own decision to make its Loans hereunder and enter into this
Agreement. Each Bank also represents that it will, independently and without
reliance upon the Administrative Agent or any other Bank, and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit analysis, appraisals and/or decisions in taking or not
taking action under this Agreement, and to make such investigation as it deems
necessary to inform itself as to the business, operations, property, financial
and/or other condition and creditworthiness of each Loan Party. Except for
notices, reports and other documents expressly required to be furnished to the
Banks by the Administrative Agent hereunder, the Administrative Agent shall not
have any duty or responsibility to provide any Bank with any credit or other
information concerning the business, operations, property, financial and other
condition or creditworthiness any Loan Party which may come into the possession
of such Agent or any of its officers, directors, employees, agents,
attorneys-in-fact or Affiliates.

             9.7 Indemnification. The Banks agree to indemnify the
Administrative Agent in its capacity as such (to the extent not reimbursed by
the Borrower and without limiting the obligation of the Borrower to do so),
ratably according to their respective Commitment Percentages, from and against
any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind whatsoever which
may at any time (including without limitation at any time following the payment
of the Loans) be imposed on, incurred by or asserted against the Administrative
Agent in any way relating to or arising out of this Agreement and the other Loan
Documents, or any documents contemplated by or referred to herein or the
transactions contemplated hereby or any action taken or omitted by the
Administrative Agent under or in connection with any of the foregoing; provided,
that no Bank shall be liable for the payment of any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting solely from the Administrative Agent's gross
negligence or willful misconduct. If any such amount with respect to which the
Banks have indemnified the Administrative Agent is recovered from the Borrower,
the Administrative Agent shall return the amount so recovered to the Banks which
so indemnified the Administrative Agent, but without interest, unless the
Borrower has paid


                                       64
<PAGE>   69
interest. The agreements in this Section shall survive the payment of the Loans
and all other amounts payable hereunder.

             9.8 The Administrative Agent in Its Individual Capacity. The
Administrative Agent and its affiliates may make loans to, accept deposits from
and generally engage in any kind of business with the Borrower and the other
Loan Parties as though the Administrative Agent were not the Administrative
Agent hereunder. With respect to its Loans made or renewed by it and any Note
issued to it, the Administrative Agent shall have the same rights and powers
under this Agreement as any Bank and may exercise the same as though it were not
the Administrative Agent, and the terms "Bank" and "Banks" shall include the
Administrative Agent in its individual capacity.

             9.9 Successor Administrative Agent. The Administrative Agent may
resign as such upon 10 days' notice to the Banks and the Borrower; provided,
that such resignation shall not become effective until a successor
Administrative Agent is appointed in accordance with this Section 9.9. If the
Administrative Agent shall resign as Administrative Agent under this Agreement,
then the Majority Banks shall appoint from among the Banks a successor agent for
the Banks which successor agent shall be approved by the Borrower, whereupon
such successor agent shall succeed to the rights, powers and duties of the
Administrative Agent, and any references to the Administrative Agent herein or
any other Loan Document shall mean such successor agent effective upon its
appointment, and the former Administrative Agent's rights, powers and duties as
such shall be terminated, without any other or further act or deed on the part
of such former Administrative Agent or any of the parties to this Agreement or
any holders of the Notes. After any retiring Administrative Agent's resignation
as such, the provisions of this Section 10.9 shall inure to its benefit as to
any actions taken or omitted to be taken by it while it was the Administrative
Agent under this Agreement.

            SECTION 10. MISCELLANEOUS

             10.1 Amendments and Waivers. None of this Agreement, any Note or
any other Loan Document, nor any terms hereof or thereof may be amended,
supplemented or modified except in accordance with the provisions of this
Section 10.1. With the written consent of the Required Banks, the Administrative
Agent, on behalf of the Banks, and the applicable Loan Party may, from time to
time, enter into written amendments, supplements or modifications hereto and to
the other Loan Documents for the purpose of adding any provisions to this
Agreement and the other Loan Documents or changing in any manner the rights of
the Banks or of the applicable Loan Party hereunder or thereunder or waiving, on
such terms and conditions as the Administrative Agent may specify in such
instrument, any of the requirements of this Agreement or the other Loan
Documents or any Default or Event of Default and its consequences; provided,
however, that no such


                                       65
<PAGE>   70
waiver and no such amendment, supplement or modification shall (a) reduce the
amount or extend the scheduled maturity of any Loan, or reduce the rate or
extend the time of payment of interest thereon, or reduce any fee payable to any
Bank hereunder, or reduce the principal amount of any Loan, or increase the
amount or extend the expiry date of any Bank's Commitment, in each case without
the written consent of each Bank affected thereby, and in the case of any
extension of the Termination Date, the written extension of the time of payment
of interest on any Loan in an aggregate amount exceeding $15,000,000 for more
than six months or the extension of the Commitment Period, without the written
consent of Lockheed Martin or (b) [INTENTIONALLY OMITTED], or (c) approve a
financial institution as an issuer of an Acceptable Letter of Credit without the
written consent of the Majority Banks or (d) amend, modify or waive any
provision of this Section 10.1, or reduce the percentage specified in the
definitions of Required Banks or Majority Banks, or consent to the assignment or

Banks, or amend, modify or waive any provision of this Section 10.1 that
requires the consent of Lockheed Martin without the written consent of Lockheed
Martin or (e) amend, modify or waive any provision of Section 9 without the
written consent of the then Administrative Agent or (f) increase the Commitments
hereunder except in accordance with Section 2.6 or (g) amend the definition of

all of the Collateral, in each case without the written consent of all of the
Banks and Lockheed Martin or (h) amend Section 2.2 or Section 2.6(a) or Section
2.6(c) without the written consent of Lockheed Martin. Any such waiver and any
such amendment, supplement or modification shall apply equally to each of the
Banks and shall be binding upon the Loan Parties, the Banks, the Administrative
Agent and all future holders of the Notes. In the case of any waiver, the Loan
Parties, the Banks and the Administrative Agent shall be restored to their
former position and rights hereunder and under the other Loan Documents, and any
Default or Event of Default waived shall be deemed to be cured and not
continuing; but no such waiver shall extend to any subsequent or other Default
or Event of Default, or impair any right consequent thereon.

<PAGE>   73
Administrative Agent, the Arranger or any such Bank, as the case may be. The
agreements in this Section 10.5 shall survive repayment of the Loans and all
other amounts payable hereunder.

             10.6 Successors and Assigns; Participations; Purchasing Banks. (a)
This Agreement shall be binding upon and inure to the benefit of the Borrower,
the Banks, the Administrative Agent, all future holders of the Notes, and their
respective successors and assigns, except that the Borrower may not assign or
transfer any of its rights or obligations under this Agreement without the prior
written consent of each Bank. Sections 2.2 and 2.6 and Clauses (a), (d) (g) and
(h) of Section 10.1 shall inure to the benefit of and be enforceable by Lockheed
Martin to the extent provided therein.

            (b) Any Bank may, in the ordinary course of its commercial banking
business and in accordance with applicable law, at any time sell to one or more
banks or other entities ("Participants") participating interests in any Loan
owing to such Bank, any Note held by such Bank, the Commitment of such Bank or
any other interest of such Bank hereunder; provided, that if the Participant is
not an Affiliate of such Bank or another Bank, such Bank shall obtain the prior
consent of the Borrower and the Administrative Agent to such sale of
participating interests (which consent shall not be unreasonably withheld or
delayed); and provided further, that such Bank shall reserve solely unto itself,
and shall not grant to any Participant, any part or all of its right to agree to
the amendment, modification or waiver of any of the terms of this Agreement, its
Note, any other Loan Document or any document related thereto, except to the
extent that such amendment, modification or waiver would reduce the principal
of, or interest on, the Loans or any fees payable hereunder, in each case to the
extent subject to such participation, or postpone the date of the final maturity
of, or any date fixed for any payment of interest on, the Loans, in each case to
the extent subject to such participation. In the event of any such sale by a
Bank of a participating interest to a Participant, such Bank's obligations under
this Agreement to the other parties to this Agreement shall remain unchanged,
such Bank shall remain solely responsible for the performance thereof, such Bank
shall remain the holder of any such Note for all purposes under this Agreement
and the Borrower, and the Administrative Agent shall continue to deal solely and
directly with such Bank in connection with such Bank's rights and obligations
under this Agreement. The Borrower agrees that if amounts outstanding under this
Agreement and the Notes are due and unpaid, or shall have been declared or shall
have become due and payable upon the occurrence of an Event of Default, each
Participant shall be deemed to have the right of setoff in respect of its
participating interest in amounts owing under this Agreement and any Note to the
same extent as if the amount of its participating interest were owing directly
to it as a Bank under this Agreement or any Note; provided, that such right of
setoff shall be subject to the obligation of such Participant to share with the
Banks,


                                       69

and the Banks agree to share with such Participant, as provided in Section 10.7.
The Borrower also agrees that each Participant shall be entitled to the benefits
of Sections 2.15, 2.16, 2.17 and 10.5 with respect to its participation in the
Commitments and the Loans outstanding from time to time; provided, that no
Participant shall be entitled to receive any greater amount pursuant to such
Sections than the transferor Bank would have been entitled to receive in respect
of the amount of the participation transferred by such transferor Bank to such
Participant had no such transfer occurred.

            (c) Any Bank may, in the ordinary course of its commercial banking
business and in accordance with applicable law, and (if the Purchasing Bank is
not an Affiliate of such Bank or an existing Bank) with the prior consent of the
Borrower and the Administrative Agent (which shall not be unreasonably withheld
or delayed), at any time sell to one or more banks or financial institutions
("Purchasing Banks") all or any part of its rights and obligations under this
Agreement and the Notes, pursuant to a Commitment Transfer Supplement, executed
by such Purchasing Bank and such transferor Bank, and delivered to the
Administrative Agent for its acceptance and recording in the Register; provided,
that (i) if the Purchasing Bank is not an Affiliate of such Bank or an existing
Bank any sale of Loans shall be in an amount equal to at least $7,500,000 (pro
rated downward ratably in connection with permanent reductions of the aggregate
Commitments) and (ii) after giving effect thereto, such Bank shall have
Commitments and Loans aggregating at least $7,500,000 (pro rated downward
ratably in connection with permanent reductions of the aggregate Commitments)
unless all of such Bank's Commitments and Loans are sold. Upon such execution,
delivery, acceptance and recording, from and after the Transfer Effective Date
determined pursuant to such Commitment Transfer Supplement, (x) the Purchasing
Bank thereunder shall be a party hereto and, to the extent provided in such
Commitment Transfer Supplement, have the rights and obligations of a Bank
hereunder with a Commitment as set forth therein, and (y) the transferor Bank
thereunder shall, to the extent provided in such Commitment Transfer
Supplement, to be released from its obligations under this Agreement (and, in
the case of a Commitment Transfer Supplement covering all or the remaining
portion of a transferor Bank's rights and obligations under this Agreement,
such transferor Bank shall cease to be a party hereto). Such Commitment
Transfer Supplement shall be deemed to amend this Agreement to the extent, and
only to the extent, necessary to reflect the addition of such Purchasing Bank
and the resulting adjustment of Commitment Percentages arising from the
purchase by such Purchasing Bank of all or a portion of the rights and
obligations of such transferor Bank under this Agreement and the Notes. If
requested by the Purchasing Bank and/or the transferor Bank, on or prior to the
Transfer Effective Date determined pursuant to such Commitment Transfer
Supplement, the Borrower, at its own expense, shall execute and deliver to
the Administrative Agent in exchange for the surrendered Note a new Note to the
order of such Purchasing



                                       70
<PAGE>   75
Bank in an amount equal to the Commitment assumed by it pursuant to such 
Commitment Transfer Supplement and, if the transferor Bank has retained a 
Commitment hereunder, a new Note to the order of the transferor Bank in an 
amount equal to the Commitment retained by it hereunder. Such new Notes shall 
be dated the Closing Date and shall otherwise be in the form of the Notes 
replaced thereby. The Note surrendered by the transferor Bank shall be returned
by the Administrative Agent to the Borrower marked "cancelled". Notwithstanding
any provision of this paragraph (c) and paragraph (e) of this Section, the 
consent of the Borrower shall not be required, and, unless requested by the 
assignee and/or the assigning Bank, new Notes shall not be required to be 
executed and delivered by the Borrower, for any assignment which occurs at any
time when any of the events described in paragraph (a)(vi) of Section 8 shall 
have occurred and be continuing.

            (d) The Administrative Agent shall maintain at its address referred
to in Section 10.2 a copy of each Commitment Transfer Supplement delivered to it
and a register (the "Register") for the recordation of the names and addresses
of the Banks and the Commitment of, and principal amount of the Loans owing to,
each Bank from time to time. The entries in the Register shall be conclusive, in
the absence of manifest error, and the Borrower, the Administrative Agent and
the Banks may (and, in the case of any Loan or other obligation hereunder not
evidenced by a Note, shall) treat each Person whose name is recorded in the
Register as the owner of the Loan recorded therein for all purposes of this
Agreement. Any assignment of a Loan or other obligation hereunder not evidenced
by a Note shall be effective only upon appropriate entries with respect thereto
being made in the Register. The Register shall be available for inspection by
the Borrower or any Bank at any reasonable time and from time to time upon
reasonable prior notice.

            (e) Upon its receipt of a Commitment Transfer Supplement executed by
a transferor Bank and a Purchasing Bank together with payment to the
Administrative Agent of a registration and processing fee of $4,000, the
Administrative Agent shall (i) promptly accept such Commitment Transfer
Supplement and (ii) on the Transfer Effective Date determined pursuant thereto
record the information contained therein in the Register and give notice of such
acceptance and recordation to the Administrative Agent, the Banks and the
Borrower.

            (f) The Borrower authorizes each Bank to disclose to any Participant
or Purchasing Bank (each, a "Transferee") and any prospective Transferee any and
all financial information in such Bank's possession concerning the Loan Parties
and their affiliates which has been delivered to such Bank by or on behalf of
any such Loan Party pursuant to this Agreement or the other Loan Documents or
which has been delivered to such Bank by or on behalf of any Loan Party in
connection with such Bank's credit evaluation of the Borrower and its affiliates
prior to becoming a


                                       71
<PAGE>   76
party to this Agreement; provided, that such Transferee or prospective
Transferee agrees in writing to be bound by the confidentiality provisions set
forth in Section 10.14 hereof.

            (g) If, pursuant to this Section 10.6, any interest in this
Agreement or any Note is transferred to any Transferee which is organized under
the laws of any jurisdiction other than the United States or any State thereof,
the transferor Bank shall cause such Transferee, concurrently with the
effectiveness of such transfer, (i) to represent to the transferor Bank (for the
benefit of the transferor Bank, the Administrative Agent and the Borrower) that
under applicable law and treaties no taxes will be required to be withheld by
the Administrative Agent, the Borrower or the transferor Bank with respect to
any payments to be made to such Transferee in respect of the Loans, (ii) to
furnish to the transferor Bank (and, in the case of any Purchasing Bank
registered in the Register, the Administrative Agent and the Borrower) either
U.S. Internal Revenue Service Form 4224 or U.S. Internal Revenue Service Form
1001 (wherein such Transferee claims entitlement to complete exemption from U.S.
federal withholding tax on all interest payments hereunder) and an Internal
Revenue Service Form W-8 or W-9 or successor applicable form (wherein such
Transferee claims exemption from United States backup withholding tax) and (iii)
to agree (for the benefit of the transferor Bank, the Administrative Agent and
the Borrower) to provide the transferor Bank (and, in the case of any Purchasing
Bank registered in the Register, the Administrative Agent and the Borrower) a
new Form 4224 or 1001 or Form W-8 or W-9 upon the expiration or obsolescence of
any previously delivered form and comparable statements in accordance with
applicable U.S. laws and regulations and amendments duly executed and completed
by such Transferee, and to comply from time to time with all applicable U.S.
laws and regulations with regard to such withholding and backup withholding tax
exemptions.

            (h) Nothing herein shall prohibit any Bank from pledging or
assigning any Loan, either directly or through the principal banking subsidiary
of the bank holding company which owns such Bank, to any Federal Reserve Bank in
accordance with applicable law.

             10.7 Adjustments; Set-off. (a) If any Bank (a "benefitted Bank")
shall receive any payment of all or part of its Loans or interest thereon, or
receive any collateral in respect of its Loans (in each case whether voluntarily
or involuntarily, by set-off, pursuant to events or proceedings of the nature
referred to in clause (a)(vi) of Section 8, or otherwise) in a greater
proportion than any such payment to and collateral received by any other Bank,
if any, in respect of such other Bank's Loans or interest thereon, or Loans or
interest thereon, such benefitted Bank shall purchase for cash from the other
Banks such portion of each such other Bank's Loans, or shall provide such other
Banks with the benefits of any such collateral, or the proceeds thereof, as
shall be necessary to


                                       72
<PAGE>   77
cause such benefitted Bank to share the excess payment or benefits of such
collateral or proceeds ratably with each of the Banks; provided, however, that
if all or any portion of such excess payment or benefits is thereafter recovered
from such benefitted Bank, such purchase shall be rescinded, and the purchase
price and benefits returned, to the extent of such recovery, but without
interest. The Borrower agrees that each Bank so purchasing a portion of another
Bank's Loans may exercise all rights of payment (including, without limitation,
rights of set-off) with respect to such portion as fully as if such Bank were
the direct holder of such portion.

            (b) In addition to any rights and remedies of the Banks provided by
law, each Bank (and its Affiliates, to the extent permitted by law) shall have
the right, without prior notice to the Borrower, any such notice being expressly
waived by the Borrower to the extent permitted by applicable law, upon any
amount becoming due and payable by the Borrower hereunder or under the Notes
(whether at the stated maturity, by acceleration or otherwise) to set off and
appropriate and apply against such amount any and all deposits (general or
special, time or demand, provisional or final), in any currency, and any other
credits, indebtedness or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or
owing by such Bank (or any such Affiliate) to or for the credit or the account
of the Borrower. Each Bank agrees promptly to notify the Borrower and the
Administrative Agent after any such set-off and application made by such Bank;
provided, that the failure to give such notice shall not affect the validity of
such set-off and application.

            10.8 Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

            10.9 Counterparts. This Agreement may be executed by one or more of
the parties to this Agreement on any number of separate counterparts and all of
said counterparts taken together shall be deemed to constitute one and the same
instrument. A set of the copies of this Agreement signed by all the parties
shall be lodged with the Borrower and the Agent.

            10.10 GOVERNING LAW. THIS AGREEMENT AND THE NOTES AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED
BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF
NEW YORK.

            10.11 Submission To Jurisdiction; Waivers. The Borrower hereby
irrevocably and unconditionally:


                                       73
<PAGE>   78
            (a) submits for itself and its property in any legal action or
proceeding relating to this Agreement or any other Loan Documents, or for
recognition and enforcement of any judgment in respect thereof, to the
non-exclusive general jurisdiction of the courts of the State of New York, the
courts of the United States of America for the Southern District of New York,
and appellate courts from any thereof;

            (b) consents that any such action or proceeding may be brought in
such courts and waives any objection that it may now or hereafter have to the
venue of any such action or proceeding in any such court or that such action or
proceeding was brought in an inconvenient court and agrees not to plead or claim
the same;

            (c) agrees that service of process in any such action or proceeding
may be effected by mailing a copy thereof by registered or certified mail (or
any substantially similar form of mail), postage prepaid, to the Borrower at its
address set forth in Section 10.2 or at such other address of which the Agent
shall have been notified pursuant thereto;

            (d) agrees that nothing herein shall affect the right to effect
service of process in any other manner permitted by law or shall limit the right
to sue in any other jurisdiction; and

            (e) waives, to the maximum extent not prohibited by law, any right
it may have to claim or recover in any legal action or proceeding referred to in
this Section any special, exemplary, punitive or consequential damages.

            10.12 WAIVERS OF JURY TRIAL. THE BORROWER, THE ADMINISTRATIVE AGENT
AND THE BANKS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY
LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR THE NOTES AND FOR ANY
COUNTERCLAIM THEREIN.

            10.13 Integration. This Agreement represents the agreement of the
Borrower, the Administrative Agent and the Banks with respect to the subject
matter hereof, and there are no promises, undertakings, representations or
warranties by the Administrative Agent or any Bank relative to the subject
matter hereof not expressly set forth or referred to herein or in the other Loan
Documents.

            10.14 Confidentiality. The Banks shall hold all non-public
information obtained pursuant to the requirements of this Agreement or any other
Loan Document which has been identified as such by a Loan Party in accordance
with their customary procedures for handling confidential information of this
nature and in accordance with safe and sound banking practices but in any event
may make disclosure reasonably required by a bona fide prospective Purchasing
Bank or Participant in connection with the contemplated transfer of any Note or
participation therein


                                       74

(subject to such prospective Purchasing Bank's or Participant's compliance with
Section 10.6(f) hereof) or as required or requested by any Governmental
Authority or representative thereof or pursuant to legal process.
