     2.   GUARANTY.

         (a) UNCONDITIONAL GUARANTY. Guarantor hereby severally,
unconditionally, absolutely and irrevocably guarantees to Agent, for the ratable
benefit of Agent, Lenders and their respective successors, indorsees,
transferees and assigns, the prompt and complete payment when due (whether at
stated maturity, by acceleration or otherwise) of an amount, if any, at any time
of determination (such amount is referred to herein as the "GUARANTEED AMOUNT")
equal to 50% of the excess, if any, as of the most recent Measurement Date, of
(x) the principal amount outstanding under the Credit Agreement (excluding
deemed capitalized interest of $31,115,827.71, as of the date hereof, and
additional interest capitalized pursuant to SECTION 2.5 of the Credit Agreement)
over (y) the principal amount outstanding under the Globalstar Bank Agreement
(excluding capitalized interest, if any). A Measurement Date shall occur on June
30 and December 31 of each year.

         (b) EXPENSES UNDER THIS GUARANTY. Guarantor also agrees to pay on
demand from time to time all expenses of Lenders or Agent (including, without
limitation, all fees, costs and disbursements of any law firm or other external
counsel) related or incidental to the collection of the Guaranteed Amount. The
Guaranteed Amount and all other obligations and covenants to be performed by
Guarantor under this Guaranty are collectively referred to herein as the
"GUARANTEED OBLIGATIONS." This Guaranty shall remain in full force and effect
until the Obligations are paid in full and the Tranche A Commitments and Tranche
B Commitments are terminated, notwithstanding that from time to time prior
thereto there may be no Obligations or the Guaranteed Amount may be zero.

         (c) GUARANTEED OBLIGATIONS UNAFFECTED. No payment or payments made by
Borrower, Guarantor or any other Person, or received or collected by Agent or
any Lender from Borrower or any other Person by virtue of any action or
proceeding or any setoff or appropriation or application, at any time or from
time to time, in reduction of or in payment of the Obligations shall be deemed
to modify, reduce, release or otherwise affect the liability of Guarantor
hereunder which liability shall continue, notwithstanding any such payment or
payments, until the Guaranteed Obligations are paid in full and the Credit
Agreement is terminated pursuant to its terms.



                                       4.
<PAGE>   5

         (d) JOINT AND SEVERAL LIABILITY. Guarantor and its successors and
assigns shall be jointly and severally liable for the payment of the Guaranteed
Obligations notwithstanding any relationship or contract of co-obligation by or
among Guarantor and its successors and assigns.

         (e) ACCELERATION OF THE GUARANTEED AMOUNT. Upon the occurrence and
during the continuance of an Event of Default (as defined in this Agreement),
then and in any such event all or any part of the Guaranteed Amount may, at the
option of the Requisite Lenders and as provided in the Credit Agreement, and
without demand, notice or legal process of any kind, be declared, and
immediately shall become, due and payable.

         (f) NOTICE OF PAYMENT UNDER GUARANTY; APPLICATION OF PAYMENTS.
Guarantor agrees that whenever, at any time, or from time to time, it shall make
any payment to Agent or any Lender on account of its liability hereunder, it
will notify such Person (and, if such Person is not Agent, Guarantor will also
notify Agent) in writing that such payment is made under this Guaranty for such
purpose. Agent, Lenders and Guarantor agrees that all payments in respect of the
Guaranteed Amount made by Guarantor pursuant to this Guaranty will be applied to
reduce the aggregate principal amount outstanding under the Credit Agreement,
and the payments will be applied in the inverse order of maturity of the
scheduled principal payments thereunder.

         (g) SUBORDINATION. Any indebtedness or other obligation of Borrower or
its Subsidiaries now or hereafter held by or owing to Guarantor under this
Guaranty is hereby subordinated in time and right of payment to all obligations
of Borrower to any or all of Agent and Lenders under the Credit Agreement and
the other Credit Documents. No amendment to subsection 2.5 of the Credit
Agreement and no amendment to the Credit Agreement which increases the amount of
any of the Commitments or which extends the Tranche B Commitment Period or the
final maturity date of any of the Loans shall be effective as to Guarantor
without its prior written consent.

     3. RIGHT OF SET-OFF. Each of Agent and each Lender is hereby irrevocably
authorized at any time and from time to time to the extent permitted by law
without notice to Guarantor, any such notice being expressly waived by
Guarantor, to set off and appropriate and apply 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 Agent or such Lender to or for the credit or the account of Guarantor,
or any part thereof in such amounts as Agent or such Lender may elect, against
or on account of the obligations and liabilities of Guarantor to Agent or such
Lender hereunder and claims of every nature and description of Agent or such
Lender against Guarantor, in any currency, whether arising hereunder, under the
Credit Agreement, any Note, any Credit Document or otherwise, as Agent or such
Lender may elect, whether or not Agent or such Lender has made any demand for
payment and although such obligations, liabilities and claims may be contingent
or unmatured. Agent and each Lender shall notify Guarantor promptly of any such
set-off and the application made by Agent or such Lender, as the case may be, of
the proceeds thereof; provided that the failure to give such notice shall not
affect the validity of such set-off and application. The rights

                                       5.
<PAGE>   6

of Agent and each Lender under this paragraph are in addition to other rights
and remedies (including, without limitation, other rights of set-off) which
Agent or such Lender may have.

     4. NO SUBROGATION. Notwithstanding any payment or payments made by
Guarantor hereunder, or any set-off or application of funds of Guarantor by
Agent or any Lender, Guarantor shall not be entitled to be subrogated to any of
the rights of Agent or any Lender against Borrower or against any collateral
security or Guaranty or right of set-off held by Agent or any Lender for the
payment of the Guaranteed Obligations, nor shall Guarantor seek or be entitled
to seek any contribution or reimbursement from Borrower in respect of payments
made by Guarantor hereunder, until all amounts owing to Agent and Lenders by
Borrower on account of the Guaranteed Obligations are paid in full and the
Tranche A Commitments and the Tranche B Commitments are terminated. If any
amount shall be paid to Guarantor on account of such subrogation rights at any
time when all of the Guaranteed Obligations shall not have been paid in full,
such amount shall be held by Guarantor in trust for Agent and Lenders,
segregated from other funds of Guarantor, and shall, forthwith upon receipt by
Guarantor, be turned over to Agent in the exact form received by Guarantor (duly
indorsed by Guarantor to Agent, if required), to be applied against the
Guaranteed Obligations, whether matured or unmatured, in accordance with the
Credit Agreement.

     5. AMENDMENTS, ETC. WITH RESPECT TO THE OBLIGATIONS; WAIVER OF RIGHTS.
Guarantor shall remain obligated hereunder notwithstanding that, without any
reservation of rights against Guarantor, and without notice to or further assent
by Guarantor, any demand for payment of any of the Obligations made by Agent or
any Lender may be rescinded by Agent or by such Lender, and any of the
Obligations continued, and the Obligations, or the liability of any other Person
upon or for any part thereof, or any collateral security or Guaranty therefor or
right of set-off with respect thereto, may from time to time, in whole or in
part, be renewed, extended, amended, modified, accelerated, compromised, waived,
surrendered or released by Agent or any Lender, and the Credit Agreement, the
Commitments thereunder, any Notes, and the other Credit Documents and any other
documents executed and delivered in connection therewith may be amended,
modified, extended, supplemented or terminated, in whole or in part, as Agent
(or the Requisite Lenders) may deem advisable from time to time, and any
collateral security, Guaranty or right of offset at any time held by Agent or
any Lender for the payment of the Obligations may be sold, exchanged, waived,
surrendered or released. Neither Agent nor any Lender shall have any obligation
to protect, secure, perfect or insure any Lien at any time held by it as
security for the Obligations or for this Guaranty or any property subject
thereto. When making any demand hereunder against Guarantor, Agent or any Lender
may, but shall be under no obligation to, make a similar demand on Borrower, and
any failure by Agent, or any Lender to make any such demand or to collect any
payments from Borrower or any release of Borrower shall not relieve Guarantor of
its obligations or liabilities hereunder, and shall not impair or affect the
rights and remedies, express or implied, or as a matter of law, of Agent or any
Lender against Guarantor. For the purposes hereof "DEMAND" shall include the
commencement and continuance of any legal proceedings.

     6. GUARANTY ABSOLUTE AND UNCONDITIONAL. Guarantor waives any and all notice
of the creation, renewal, extension or accrual of any of the Obligations and
notice of or proof of reliance by Agent or any Lender upon this Guaranty or
acceptance of this Guaranty; the Obligations, and any of them, shall
conclusively be deemed to have been created, contracted or

                                       6.
<PAGE>   7

incurred, or renewed, extended, amended or waived, in reliance upon this
Guaranty; and all dealings between Borrower and Guarantor, on the one hand, and
Agent and Lenders, on the other, shall likewise be conclusively presumed to have
been had or consummated in reliance upon this Guaranty. Guarantor waives
diligence, presentment, protest, demand for payment and notice of default or
nonpayment to or upon Borrower with respect to the Obligations. This Guaranty
shall be construed as a continuing, absolute and unconditional guarantee of
payment without regard to:

         (a) the validity, regularity or enforceability of the Credit Agreement,
any Note, or any other Credit Document, any of the Obligations or any other
collateral security therefor or Guaranty or right of offset with respect thereto
at any time or from time to time held by Agent or any Lender;

         (b) any defense, set-off or counterclaim (other than a defense of
payment or performance or release as a result of the termination of this
Guaranty in accordance with its terms) which may at any time be available to or
be asserted by Borrower against Agent or any Lender; or

         (c) any other circumstance whatsoever (with or without notice to or
knowledge of Borrower or Guarantor) which constitutes, or might be construed to
constitute, an equitable or legal discharge of Borrower for the Obligations, or
of Guarantor under this Guaranty, in bankruptcy or in any other instance. When
pursuing its rights and remedies hereunder against Guarantor, Agent and any
Lender may, but shall be under no obligation to, pursue such rights and remedies
as it may have against Borrower or any other Person or against any collateral
security or Guaranty for the Obligations or any right of offset with respect
thereto, and any failure by Agent or any Lender to pursue such other rights or
remedies or to collect any payments from Borrower or any such other Person or to
realize upon any such collateral security or guarantee or to exercise any such
right of offset, or any release of Borrower or any such other Person or of any
such collateral security, guarantee or right of offset, shall not relieve
Guarantor of any liability hereunder, and shall not impair or affect the rights
and remedies, whether express, implied or available as a matter of law, of Agent
or any Lender against Guarantor. This Guaranty shall remain in full force and
effect and be binding in accordance with and to the extent of its terms upon
Guarantor and its successors and assigns thereof, and shall inure to the benefit
of Agent and Lenders, and their respective successors, indorsees, transferees
and assigns, until all the Obligations and the other obligations of Guarantor
under this Guaranty shall have been satisfied by payment in full and the Tranche
A Commitments and the Tranche B Commitments shall be terminated, and
notwithstanding that from time to time during the term of the Credit Agreement
Borrower may be free from any Obligations. Guarantor shall not be released from
its obligations under this Guaranty because of the failure of any Subsidiary
Guarantor under the Subsidiary Guaranty to perform its obligations thereunder.

     7. EFFECTIVENESS; REINSTATEMENT. Application of the terms and conditions,
covenants and Events of Default contained in this Guaranty shall be suspended
during such time or times the Guaranteed Amount is zero. This Guaranty shall
continue to be effective, or be reinstated, as the case may be, if at any time
payment, or any part thereof, of any of the Guaranteed Obligations is rescinded
or must otherwise be restored or returned by Agent or any Lender upon the
insolvency, bankruptcy, dissolution, liquidation or reorganization of Borrower


                                       7.
<PAGE>   8

or upon or as a result of the appointment of a receiver, intervenor or
conservator of, or trustee or similar officer for, Borrower or any substantial
part of its property, or otherwise, all as though such payments had not been
made.

     8. PAYMENTS. Guarantor hereby agrees that the Guaranteed Obligations will
be paid without set-off or counterclaim in U.S. Dollars to Agent at Agent's
Payment Office, and to any Lender at its Domestic Lending Office.

     9. REPRESENTATIONS AND WARRANTIES. In order to induce Lenders to make the
Loans pursuant to the Credit Agreement, Guarantor hereby represents and warrants
to Agent and to each Lender as of the date of this Agreement that except as
disclosed in its filings with the Securities and Exchange Commission:

         (a) FINANCIAL CONDITION. The audited financial statements of Guarantor
on a consolidated basis at December 31, 1999, copies of which have been filed
with the Securities Exchange Commission, and present fairly the financial
condition and results of operations of Guarantor as at such date.

         (b) NO CHANGE. Since December 31, 1999:

               (i) there has been no change in the business, operations,
property or financial or other condition of Guarantor that has or could
reasonably be expected to have a Material Adverse Effect; and

               (ii) no dividends or other distributions have been declared, paid
or made upon any shares of common stock of Guarantor nor have any shares of
common stock of Guarantor been redeemed, retired, purchased or otherwise
acquired for value by Guarantor.

         (c) CORPORATE EXISTENCE; COMPLIANCE WITH LAW. Guarantor and each of its
Subsidiaries (i) is duly organized, validly existing and in good standing under
the laws of the jurisdiction of its incorporation or organization, (ii) has the
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, (iii) is duly qualified as a foreign
corporation 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 (iv) 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.

         (d) CORPORATE POWER; AUTHORIZATION; ENFORCEABLE OBLIGATIONS. Guarantor
has the corporate power and authority and the legal right to make, deliver and
perform this Guaranty and has taken all necessary corporate action to authorize
the execution, delivery and performance of this Guaranty. Except as set forth on
Schedule 9(d), no consent or authorization of, filing with or other act by or in
respect of any Governmental Authority is required in connection with the
execution, delivery, performance, validity or enforceability of this Guaranty,
none other than those which have been obtained or made and are in full force and
effect. This Guaranty has been duly executed and delivered by Guarantor. This
Guaranty constitutes a legal,

                                       8.
<PAGE>   9

valid and binding obligation of Guarantor enforceable against Guarantor 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).

         (e) NO LEGAL BAR. The execution, delivery and performance of this
Guaranty will not violate any Requirement of Law or any Contractual Obligation
applicable to Guarantor or any of its Subsidiaries, and will not result in, or
require, the creation or imposition of any Lien on any of its properties or
revenues pursuant to any Requirement of Law or Contractual Obligation.

         (f) NO MATERIAL LITIGATION. No litigation, investigation or proceeding
of or before any arbitrator or Governmental Authority is pending or, to the
knowledge of Guarantor, threatened by or against Guarantor or any of its
Subsidiaries or against any of its or their respective properties or revenues
(i) with respect to this Guaranty or any of the transactions contemplated hereby
or thereby, or (ii) which could reasonably be expected to have a Material
Adverse Effect.

         (g) NO DEFAULT. Guarantor is not in default under or with respect to
any Contractual Obligation in any respect which could reasonably be expected to
have a Material Adverse Effect.

         (h) OWNERSHIP OF PROPERTY. Guarantor 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.

         (i) TAXES. Guarantor has filed or caused to be filed all tax returns
which to the knowledge of Guarantor 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 Guarantor, 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 Guarantor, 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.

         (j) FEDERAL REGULATIONS. Guarantor is not engaged in the business of
extending credit for the purpose of "purchasing" or "carrying" "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.

         (k) 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

                                       9.
<PAGE>   10

deemed made with respect to any Plan which has resulted or could reasonably be
expected to result in a liability to Guarantor 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 $1,000,000, the value of the assets of such Plan
allocable to such accrued benefits. Neither Guarantor nor any Commonly
Controlled Entity has had a complete or partial withdrawal from any
Multiemployer Plan, and neither Guarantor nor any Commonly Controlled Entity
would become subject to any liability under ERISA if Guarantor 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
