Advance. Thereafter, interest shall continue to be computed for the actual
number of days elapsed on the basis of a year of 365 days unless a Fixed Rate is

a 30-day month and 360-day year. Notwithstanding anything to the contrary
herein, the total amount of Borrower's Fixed Rate debt at any given time
hereunder shall not exceed seventy five percent (75%) of the Commitment.

                  (i)      Variable Rate. If Advances are made at the Variable
                           Rate, such Variable Rate shall apply until the
                           Maturity Date, except as provided herein below.

                  (ii)     Fixed Rate. If the Borrower elects a Fixed Rate, such
                           Fixed Rate as is available and in effect for loans
                           similarly classified pursuant to Lender's policies
                           and procedures then in effect at the time of the
                           election shall apply to such Advance until the
                           Adjustment Date. Upon notice given by the Borrower
                           five (5) Business Days prior to such Adjustment Date,
                           Borrower may elect to reset the interest rate to such
                           Fixed Rate as is available and in effect at the time
                           of such Adjustment Date. Such reset Fixed Rate shall
                           apply to that portion of the outstanding principal
                           balance of the Loan elected to have a Fixed Rate from
                           the Adjustment Date until a

                                       5
<PAGE>   6

                           new Adjustment Date or the Maturity Date. If Borrower
                           does not elect to reset the Fixed Rate, the Variable
                           Rate shall apply to the outstanding principal balance
                           of the Loan that had been bearing interest at the
                           Fixed Rate prior to such Adjustment Date, from such
                           Adjustment Date to the Maturity Date.

                  (iii)    Conversion to Different Interest Program.

                           (A)      Variable Rate to Fixed Rate. Subject to the
                                    conditions set forth herein, the Borrower
                                    may convert from the Variable Rate to the
                                    Fixed Rate for a portion of the principal
                                    amount of the Commitment then outstanding at
                                    any time Provided the Lender offers a Fixed
                                    Rate at such time, subject to the seventy
                                    five percent (75%) Fixed Rate debt
                                    limitation set forth above.

                           (B)      Fixed Rate to Variable Rate. The Borrower
                                    may convert from a Fixed Rate to the
                                    Variable Rate: (1) on an Adjustment Date or
                                    (2) at any other time, provided that the
                                    Borrower shall pay Lender any applicable
                                    Make-Whole Premium.

         2.04     PREPAYMENTS. (a) Optional Prepayment. If the Loan bears
interest at the Variable Rate the Borrower may opt to prepay the Loan or any
portion thereof, as the case may be, at any time subject to the terms hereof and
provided that the Borrower shall pay a prepayment fee in an amount established
by Lender, up to maximum of fifty (50) basis points times the amount being
prepaid. If the Loan bears interest at the Fixed Rate, the Borrower may opt to
prepay the Loan on an Adjustment Date or any such other date provided that the
Borrower shall pay a prepayment fee in an amount established by Lender, up to a
maximum of fifty (50) basis points times the amount being prepaid plus any
applicable Make-Whole Premium. All prepayments shall be accompanied by payment
of accrued and unpaid interest on the amount of and to the date of the
prepayment. All prepayments shall be applied first to fees, second to the
payment of accrued and unpaid interest and then to the unpaid balance of the
principal amount of the Loan.

         (b) Mandatory Prepayment. Beginning once Borrower's audited fiscal
year-end EBITDA is greater than zero, Lender shall have the option, to be
elected annually, to require Borrower to make annual mandatory prepayments of
the Loan in an amount equal to fifty percent (50%) of Borrower's Excess Cash
Flow within 120 days of the close of Borrower's fiscal year. All mandatory
prepayments shall be applied first to fees, second to the payment of accrued and
unpaid interest, and then proratably to the unpaid balance of the principal
amount of the Loan or any other loans by and between Borrower and Lender in
inverse order of Maturity Date.  All mandatory prepayments shall not be subject
to a prepayment fee.

         2.05     5% SUBORDINATED CAPITAL CERTIFICATES. The Borrower shall
purchase SCCs which in the aggregate shall not exceed the amount specified in
Schedule 1 hereto. Unless otherwise requested in writing by the Borrower prior

                                       6
<PAGE>   7

(5%) of each such Advance, and each such SCC shall be paid for with proceeds of
such Advance. The Lender agrees to deliver the SCCs on or about the date on
which the SCCs have been paid for in full. The SCCs shall bear no interest and
shall mature in accordance with the terms thereof.

                           business.

                  (e)      OTHER OBLIGATIONS. Default by the Borrower in the

                           receiver, liquidator, assignee, custodian, trustee,
                           sequestrator or similar official, or ordering the

                           for a period of sixty (60) consecutive days or the
                           Borrower or any Subsidiary or guarantor shall
                           commence a voluntary case under any applicable
                           bankruptcy, insolvency or other similar law now or
                           hereafter in effect, or under any such law, or
                           consent to the appointment or taking of possession by
                           a receiver, liquidator, assignee, custodian or

                           make any general assignment for the benefit of
                           creditors. Notwithstanding anything to the contrary
                           herein, if the Primary Guarantor shall be subject to
                           the provisions hereunder, then Borrower shall have
                           thirty (30) days after the occurrence of such event
                           to provide Lender with an executed substitute
                           guaranty, in a form and from a guarantor,
                           satisfactory to Lender. Failure to provide such
                           substitute guaranty within such thirty (30) day
                           timeframe shall constitute an Event of Default
                           hereunder.

                  (g)      DISSOLUTION OR LIQUIDATION. Other than as provided in
                           subsection (f) above, the dissolution or liquidation
                           of the Borrower or any Subsidiary or guarantor, or
                           failure by the Borrower or any Subsidiary or
                           guarantor promptly to forestall or remove any
                           execution, garnishment or attachment of such
                           consequence as will materially impair its ability to
                           continue its

                                       16

                           business or fulfill its obligations and such
                           execution, garnishment or attachment shall not be
                           vacated within sixty (60) days. Notwithstanding
                           anything to the contrary herein, if the Primary
                           Guarantor shall be subject to the provisions
                           hereunder, then Borrower shall have thirty (30) days
                           after the occurrence of such event to provide Lender
                           with an executed substitute guaranty, in a form and
                           from a guarantor, satisfactory to Lender. Failure to
                           provide such substitute guaranty within such thirty
                           (30) day timeframe shall constitute an Event of
                           Default hereunder.

                  (h)      FINAL JUDGMENT. A final non-appealable judgment in
                           excess of $100,000 shall be entered against the
                           Borrower and shall remain unsatisfied or without a
                           stay for a period of sixty (60) days.

                  (i)      GUARANTOR DEFAULT. Default by the Primary Guarantor
                           in the payment when due of any money owed to Lender
                           under any applicable guaranty between Lender and such
                           guarantor(s) related to this Loan.

         9.       RIGHTS AND REMEDIES

         9.01     RIGHTS AND REMEDIES OF THE LENDER. Upon the occurrence of an
Event of Default the Lender may, subject to:

                  (i)      thirty (30) days' prior written notice during which
                           time Borrower shall have the opportunity to cure said
                           Event of Default except with respect to Obligations
                           pursuant to 8(b) for which Borrower shall be provided
                           five (5) days' prior written notice, and 8(f) and
                           8(g) above which shall require no notice or demand
                           and shall have no period to cure; and

                  (ii)     compliance, if required, with the rules and
                           regulations of the FCC and any state public service
                           or utilities commission having jurisdiction;

exercise in any jurisdiction in which enforcement hereof is sought, the
following rights and remedies, in addition to all rights and remedies available
to the Lender under applicable law, all such rights and remedies being
cumulative and enforceable alternatively, successively or concurrently:

                  (a)      Declare all unpaid principal outstanding on the Note,
                           all accrued and unpaid interest thereon, and all
                           other Obligations to be immediately due and payable
                           and the same shall thereupon become immediately due
                           and payable without presentment, demand, protest or
                           notice of any kind, all of which are hereby expressly
                           waived.

                  (b)      Institute any proceeding or proceedings to enforce
                           the Obligations owed to, or any liens in favor of the
                           Lender.

                                       17
<PAGE>   18

                  (c)      Pursue all rights and remedies available to the
                           Lender that are contemplated by the Mortgage or the
                           Pledge in the manner, upon the conditions, and with
                           the effect provided in the Mortgage or the Pledge,
                           including but not limited to a suit for specific
                           performance, injunctive relief or damages.

         9.02     CUMULATIVE NATURE OF REMEDIES. Nothing herein shall limit the
right of the Lender, subject to notice and right to cure provisions contained
herein, to pursue all rights and remedies available to a creditor following the
occurrence of an Event of Default subject to compliance, if required, with the
rules and regulations of the FCC and any state public service or utilities
commission having jurisdiction. Each right, power and remedy of the Lender in
this Agreement and/or the Other Agreements shall be cumulative and concurrent
and recourse to one or more rights or remedies shall not constitute a waiver or
any other right, power or remedy.

         9.03     COSTS AND EXPENSES. Borrower agrees to pay and to be liable
for any and all expenses, including attorney's fees and court costs, incurred by
the Lender in exercising or enforcing any of its rights hereunder or under the
Other Agreements, together with interest thereon at the rate and determined in
the manner provided in the Mortgage. Subject to the Mortgage and applicable law,
the Lender may apply all Collateral and proceeds of all Collateral to the
Obligations in any manner which the Lender, in its sole discretion, deems
appropriate, and Borrower shall continue to be liable for any deficiency.

         9.04     LATE PAYMENT CHARGES. If payment of any principal and/or
interest due under the terms of the Note is not received at the office of the
Lender in Herndon, Virginia, or as the Lender may otherwise designate to the
Borrower, within such time period as the Lender may prescribe from time to time
in its policies in connection with any late payment charges (such unpaid amount
of principal and/or interest being herein called the "delinquent amount" and the
period beginning after such due date until payment of the delinquent amount
being herein called the late-payment period), the Borrower will pay to the
Lender, in addition to all other amounts due under the terms of the Note, the
Mortgage, and this Agreement any late-payment charge as may be fixed by the
Lender from time to time, on the delinquent amount for the late-payment period.
Provided, however, no late payment charge shall exceed an amount equal to the
then prevailing bank prime rate published in the "Money Rates" column of the
Eastern edition of the Wall Street Journal plus three percent (3%) per annum on
the delinquent amount computed over the late-payment period on the basis of a
365-day year.

         9.05     LENDER' SETOFF. The Lender shall have the right in addition to
all other rights and remedies available to it to setoff and to recover against
any or all of the Obligations due to Lender, any monies now and hereafter owing
to Borrower by the Lender, including but not limited to any monies owed by
Lender to Borrower as a result of Borrower's SCC investments. Borrower waives
all rights of setoff, deduction, recoupment or counterclaim.

         10.      MISCELLANEOUS

         10.01    PERFORMANCE FOR BORROWER. Borrower agrees and hereby
authorizes that the Lender may, in its sole discretion, but the Lender shall not
be obligated to, advance funds on

                                       18
<PAGE>   19

behalf of Borrower without prior notice to Borrower, in order to insure
Borrower's compliance with any material covenant, warranty, representation or
agreement of Borrower made in or pursuant to this Agreement or any of the Other
Agreements, to preserve or protect any right or interest of the Lender in the
Collateral or under or pursuant to this Agreement or any of the Other
Agreements, including without limitation, the payment of any insurance premiums
or taxes and the satisfaction or discharge of any judgment or any Lien upon the
Collateral or other property or assets of Borrower, provided, however, that the
making of any such advance by the Lender shall not constitute a waiver by the
Lender of any Event of Default with respect to which such advance is made nor
relieve Borrower of any such Event or Default, Borrower shall pay to the Lender
upon demand all such advances made by the Lender with interest thereon at the
rate and determined in the manner provided in the Note. All such advances shall
be deemed to be included in the Obligations and secured by the security interest
granted the Lender hereunder to the extent permitted by law.

         10.02    EXPENSES AND FILING FEES. Whether or not any of the
transactions contemplated hereby shall be consummated, Borrower agrees to pay to
the Lender at Closing or thirty (30) days after the execution and delivery
hereof, whichever is earlier, all expenses of the Lender in connection with the
filing or recordation of all financing statements and instruments as may be
required by the Lender at the time of, or subsequent to, the execution of this
Agreement including, without limitation, all documentary stamps, recordation and
transfer taxes and other costs and taxes incident to recordation of any document
or instrument in connection herewith. Borrower agrees to save harmless and
indemnify the Lender from and against any liability resulting from the failure
to pay any required documentary stamps, recordation and transfer taxes,
recording costs, or any other expenses incurred by the Lender in connection with
this Agreement. The provisions of this Subsection 10.02 shall survive the
execution and delivery of this Agreement and the payment of all other
Obligations.

         10.03    WAIVERS BY BORROWER. Borrower hereby waives, to the extent the
same may be waived under applicable law: (a) in the event the Lender seeks to
repossess any or all of the Collateral by judicial proceedings, any bond(s) or
demand(s) for possession which otherwise may be necessary or required; (b)
presentment demand for payment protest and notice of non-payment and all
exemptions; and (c) substitution, impairment exchange or release of any
collateral security for any of the Obligations. Borrower agrees that the tender
may exercise any or all of its rights and/or remedies hereunder and under the
Other Agreements without resorting to and without regard to security or sources
of liability with respect to any of the Obligations.

         10.04    WAIVERS BY THE LENDER. Neither any failure nor any delay on
the part of the Lender in exercising any right, power or remedy hereunder or
under any of the Other Agreements shall operate as a waiver thereof, nor shall a
single or partial exercise thereof preclude any other or further exercise
thereof or the exercise of any other right, power or remedy.

         10.05    LENDER'S RECORDS. Absent bad faith or manifest error, every
statement of account or reconciliation rendered by the Lender to Borrower with
respect to any of the Obligations shall be presumed conclusively to be correct
and shall contribute an account stated

                                       19
<PAGE>   20

between the Lender and Borrower unless, within forty five (45) Business Days
after such statement or reconciliation shall have been mailed, postage prepaid,
to Borrower, the Lender shall receive written notice of specific objection
thereto.

         10.06    MODIFICATIONS. No modification or waiver of any provision of
this Agreement, the Note, the Mortgage, the Pledge or any of the Other
Agreements, and no consent to any departure by Borrower therefrom shall in any
event be effective unless the same shall be in writing, and then such waiver or
consent shall be effective only in the specific instance and for the purpose for
which given. No notice to or demand upon Borrower in any case shall name
Borrower to any other or further notice or demand in the same, similar or other
circumstances.

         10.07    NOTICES. All notices, requests and other communications
provided for herein including, without limitation, any modifications of, or

Class One - 70% of the patronage capital is retired in cash shortly after the
end of the year in which it was allocated and (b) Class Two - 30% of the
patronage capital allocation is retired on Lender's Board approved rotation
cycle, which is currently 15 years.

Lender, make, execute, acknowledge and deliver all such further and supplemental

conveyances as may be reasonably requested by the Lender to effectuate the
intention of this Agreement and to provide for the securing and payment of the
principal of and interest on the Note according to the terms thereof.

         10.20    LENDER'S APPROVAL. Wherever prior written approval or consent
of Lender is required under the terms and conditions of this Agreement, Lender
hereby agrees to not unreasonably withhold or delay said approval.

or on behalf of the Company, the Parent or their Subsidiaries to the Purchaser
in connection with this Agreement and the transactions contemplated hereby,
contains any untrue statement of any material fact, or omits to state any
material fact that is necessary in order to make the statements contained herein
or therein, in the light of the circumstances under which they were made,
complete and not misleading. There exists no undisclosed fact or circumstance
which, to the knowledge of Company, the Parent or any of their Subsidiaries,
would reasonably be likely to result in a Material Adverse Effect.

         (k)      Compliance with Securities Laws. Assuming the accuracy of the
representations and warranties of the Purchaser contained in Section 6 hereof,
the offer and sale of the Note and the Capital Stock acquired pursuant to the
Acquisition Documents, are not required to be registered pursuant to the
provisions of Section 5 of the Securities Act or any state securities laws.
Neither the Company nor any agent on its behalf has solicited or will solicit
any offers to sell or has offered to sell or will offer to sell all or any part
of the Note, and the Capital Stock to be acquired pursuant to the Acquisition
Documents, to any Person so as to bring the sale of Note, and the Capital Stock
to be acquired pursuant to the Acquisition Documents, by the Company within the
registration provisions of the Securities Act or any state securities laws. All
prior offerings and sales of securities of the Company, the Parent and their
Subsidiaries were in compliance with all applicable federal and state securities
laws.

         (l)      No Brokers. The Company has not dealt with any broker, finder,
commission agent or other similar Person in connection with the offer and sale
of the Note by the Company to the Purchaser or the transactions contemplated by
this Agreement, and the Company is not under any obligation to pay any broker's
fee, finder's fee or commission in connection with such transactions.

         (m)      Financial Statements.

                  (i)      The audited Financial Statements, complete and
         correct copies of which have previously been furnished to the Purchaser
         by the Company, present fairly and accurately the financial condition,
         results of operations and changes in financial position of the Company
         and it Subsidiaries in accordance with GAAP, consistently applied, as
         of the dates and for the periods set forth therein. The unaudited
         Financial Statements, complete and correct copies of which have
         previously been furnished to the Purchaser by the Company, present
         fairly and accurately the financial condition and results of operations
         of the Company and its

                                       18
<PAGE>   24

         Subsidiaries as of the dates and for the periods set forth therein,
         subject to the lack of footnote disclosure and changes resulting from
         normal year-end adjustments, none of which, alone or in the aggregate,
         would have a Material Adverse Effect. Since December 31, 1998 there has
         been no Material Adverse Change.

                  (ii)     As an inducement to the Purchaser to enter into this
         Agreement and the other Transaction Documents, the Company has caused
         to be provided to the Purchaser the projections listed on Schedule 4(e)
         (the "Projections") prepared by the Company. The Company represents and
         warrants that, after a good faith review of information currently
         available: (A) the assumptions underlying the Projections are
         reasonable; (B) the Projections are based upon good faith and diligent
         estimates of the anticipated operating results and consummation of the
         Subdebt Investment; and (C) no event has occurred and no circumstance
         has arisen since the date of the Projections which would render the
         Projections or the assumptions underlying the Projections misleading or
         no longer reasonable.

         (n)      Absence of Undisclosed Liabilities. Neither the Company, the
Parent nor any of their Subsidiaries has any material obligation or liability
(whether accrued, absolute, contingent, unliquidated or otherwise, whether or
not known to the Company, whether due or to become due and regardless of when
asserted), other than (i) liabilities set forth on the Latest Balance Sheet
(including any notes thereto), (ii) liabilities and obligations which have
arisen after the date of the Latest Balance Sheet in the ordinary course of
business and which do not individually or in the aggregate have a Material
Adverse Effect and (iii) obligations expressly disclosed in the other schedules
and exhibits attached to this Agreement.

         (o)      Title To Properties and Assets. Each of the Company, the
Parent and each of their Subsidiaries has good and marketable title in fee
simple (or its equivalent under applicable law) to all real property owned by
it. Each of the Company, the Parent and each of their Subsidiaries has good and
valid title to, or a valid leasehold interest in, all other properties and
assets used by it, located on its premises or shown on the Latest Balance Sheet
or acquired thereafter, free and clear of all Liens, other than for (i)
properties and assets disposed of in the ordinary course of business since the
date of the Latest Balance Sheet, (ii) Liens disclosed on the Latest Balance
Sheet (including the notes thereto) or (iii) Permitted Liens. All facilities,
machinery, equipment, fixtures, vehicles and other properties owned, leased or
used by the Company, the Parent or any of their Subsidiaries are in good
operating condition and repair and are reasonably fit and usable for the
purposes for which they are being used. Neither the Company, the Parent nor any
Subsidiary is in violation of any material zoning, building or safety ordinance,
regulation or requirement or other law or regulation applicable to the operation
of its owned or leased properties. The Affiliates of the Company do not own or
lease any properties or assets that are used by the Company, the Parent or any
of their Subsidiaries except as set forth on Schedule 5(s).

         (p)      Contracts and Commitments. Schedule 5(p) lists, as of the
Closing Date, each "material contract" (within the meaning of Item 601(b)(10) of
the Regulation S-K under the Exchange Act) to which either the Company, the
Parent or any of their Subsidiaries is a party, by which it or their respective
properties is bound or to which it is subject (collectively, the "Material
Contracts"), and also indicates the parties thereto. As of the Closing Date, (i)
to the knowledge of the

                                       19
<PAGE>   25

Company, each Material Contract is in full force and effect and is enforceable
by the Company, the Parent or their Subsidiary that is a party thereto in
accordance with its terms and (ii) neither the Company, the Parent nor any of
their Subsidiaries (nor, to the knowledge of the Company, any other party
thereto) is in breach of or default under any Material Contract in any material
respect or has given notice of termination or cancellation of any Material
Contract.

         (q)      Employees. Set forth on Schedule 5(q) is a complete list of
all employment agreements between the Company, the Parent or any of their
Subsidiaries and any employee of the Company, the Parent or any of their
Subsidiaries, respectively. Except as set forth on Schedule 5(q), the Company is
not aware that any executive or key employee of the Company, the Parent or any
of their Subsidiaries or any group of employees of the Company, the Parent or
any of their Subsidiaries has any plans to terminate employment with the
Company, the Parent or any of their Subsidiaries. With respect to employees who
are terminating their employment, Schedule 5(q) provides a true and correct
summary of all severance benefits being provided by the Company, the Parent or
any of their Subsidiaries to such employees. Neither the Company, the Parent nor
any of their Subsidiaries nor, to the Company's best knowledge, any of its or
their employees, is subject to any noncompete, nondisclosure, confidentiality,
employment, consulting, collective bargaining or similar agreement relating to,
affecting or in conflict with, the present or proposed business activities of
the Company, the Parent or any of their Subsidiaries or any such Person's right
to participate in the affairs of the Company, the Parent or any of their
Subsidiaries.

         (r)      Compliance with Laws. Neither the Company, the Parent nor any
of their Subsidiaries has violated any Requirement of Law, which violation would
reasonably be expected to have a Material Adverse Effect, and neither the
Company, the Parent nor any of their Subsidiaries has received notice of any
such violation.

         (s)      Transactions with Affiliates. Except as set forth on Schedule
5(s), there are no Contractual Obligations of the Company, the Parent or any of
their Subsidiaries to any of the officers, directors, managers, shareholders,
members, employees, Affiliates or their respective Affiliates, or Related
Parties, of the Company, the Parent or any of their Subsidiaries other than (i)
for payment of salary for services rendered, (ii) reimbursement for reasonable
expenses incurred on behalf of the Company, the Parent or their Subsidiaries,
(iii) for standard employee benefits made generally available to all employees
of the Company (including stock option agreements outstanding under any stock
option plan approved by the Board of Directors of the Company) and (iv) pursuant
to any of the Transaction Documents. None of the officers, directors, managers,
shareholders, members, employees, Affiliates, or their respective Affiliates or
Related Parties, of the Company, the Parent or any of their Subsidiaries has
incurred Indebtedness to the Company or has any direct or indirect ownership
interest in any Person with which the Company is affiliated or, to the Company's
best knowledge, with which the Company, the Parent or any of their Subsidiaries
has a business relationship except that such Person may own stock in publicly
traded companies. Other than as set forth on Schedule 5(s), no officer,
director, manager, shareholder, member, employee, Affiliate, or any of their
respective Affiliates or Related Parties, of the Company, the Parent or any of
their Subsidiaries, is, directly or indirectly, interested in any material
Contractual Obligation with the Company. Except as may be expressly disclosed in
notes to the Financial Statements, the Company is not a guarantor or indemnitor
of any Indebtedness of any other Person.

                                       20

the premises owned or leased by the Company or any of its Subsidiaries or the
businesses therein conducted. There has been no spill, discharge, release or
cleanup of any Hazardous Material with respect to such premises (except spills,
discharges or releases in the ordinary course of business and permitted by
applicable Environmental Law (as defined below)) ("Hazardous Discharge"), and,
accordingly, such properties are clean of all such Hazardous Materials. To the
extent the premises owned or leased by the Company, the Parent or any of their
Subsidiaries are used for the handling, storage, transportation or disposal of

of common law now or hereafter in effect and in each case as amended, and any
judicial or administrative interpretation thereof, including any judicial or
administrative order, consent decree or judgment, relating to the environment,

indemnification, cost recovery, compensation or injunctive relief resulting from
Hazardous Materials or arising from alleged injury or threat of injury to
health, safety or the environment.

         (u)      Solvency. After giving effect to the Acquisition and the other
transactions contemplated by this Agreement and the other Transaction Documents,
(i) the fair value of the Company's assets exceeds the book value of the
Company's liabilities, (ii) the Company is generally able to pay its debts as
they become due and payable and (iii) the Company does not have unreasonably
small capital to carry on its business as it is currently conducted.

         (v)      Certain Federal Regulations. Neither the Company, the Parent
nor any Person controlling, controlled by or under common control with the
Company or the Parent is an "investment company" within the meaning of the
Investment Company Act of 1940, as amended. The Company and the Parent are not
an "affiliated person" of, or "promoter" or "principal underwriter" for, an
"investment company," as such terms are defined under the Investment Company Act
of 1940, as amended. The Company is not engaged principally or as one of its
activities in the business of extending credit for the purpose of "purchasing"
or "carrying" any "margin stock" (as each such term is defined or used in
Regulations G and U of the Board of Governors of the Federal Reserve System). No
part of the proceeds of the Note will be used for purchasing or carrying margin
stock or for any purpose which violates, or which would be inconsistent with,
the provisions of Regulations G, T, U or X of such Board of Governors.

         (w)      Acquisition and Credit Documents. The Acquisition Documents
and Credit Documents delivered to the Purchaser pursuant to Section 4(h)
comprise a full and complete copy of all agreements between the parties thereto
with respect to the subject matter thereof and all transactions related thereto,
and there are no agreements or understandings, oral or written, or side
agreements not contained therein that relate to or modify the substance thereof.

         (x)      Use of Proceeds. The proceeds from the issuance of the Note
will be used for the purposes set forth on Schedule 5(x) and, in furtherance of
such purposes, shall be disbursed to the Persons (including, without limitation,
Subsidiaries of the Company) listed on such Schedule 5(x) in the amounts set
forth opposite their respective names.

         (y)      Employee Benefit Plans. Except as set forth in Schedule 5(y),
the Company and the Parent do not maintain or contribute to any employee benefit
plan, stock option, bonus or incentive plan, severance pay policy or agreement,
deferred compensation agreement, or any similar plan or agreement. Each of the
Company and its ERISA Affiliates is in compliance in all material respects with
the applicable provisions of ERISA and the regulations and published
interpretations thereunder. No ERISA Event has occurred as to which the Company
or any ERISA Affiliate was required to file a report with the PBGC, and the
present value of all benefit liabilities under each Plan (based on those
assumptions used to fund such Plan) did not, as of the last annual valuation
date applicable thereto, exceed the value of the assets of such Plan. The
Company and its ERISA Affiliates are not required to make, or accrue an
obligation to make, contributions to any Multiemployer Plan and, during the past
five years, neither the Company nor any ERISA Affiliate has made, has been
required to make, or accrued an obligation to make, any contribution to any
Multiemployer Plan. There are no

                                       22
<PAGE>   28

unfunded obligations of the Company or the Parent under any retirement, pension,
profit-sharing, deferred compensation plan or similar program.

         (z)      Intellectual Property.

                  (i)      Schedule 5(z) sets forth a complete and correct list
         of all Intellectual Property that is owned by the Company, the Parent
         and their Subsidiaries (the "Owned Intellectual Property"). To the
         knowledge of the Company, the Owned Intellectual Property constitutes
         all Intellectual Property used by, and necessary for the conduct of the
         business of, the Company, the Parent and their Subsidiaries. The Owned
         Intellectual Property does not infringe the rights of any other Person
         in respect of any Intellectual Property, and none of the Owned
         Intellectual Property is being infringed in any material respect by any
         other Person. To the knowledge of the Company, neither the Company nor
         the Parent nor any of the Company's nor the Parent's employees or
         consultants nor any of the Subsidiaries or any of their employees or
         consultants has any agreements or arrangements with former employers of
         such employees or consultants relating to any Intellectual Property of
         such employers, which interfere or conflict with the performance of
         such employee's or consultant's duties for the Company, the Parent or
         such Subsidiary or results in any former employers of such employees
         and consultants having any rights in, or claims on, the Owned
         Intellectual Property. To the knowledge of the Company, the activities
         of the Company's or the Parent's employees and consultants and the
         employees and consultants of each Subsidiary on behalf of the Company,
         the Parent or such Subsidiary do not violate any agreements or
         arrangements which any such employees have with former employers. Each
         current and former employee of the Company, the Parent and their
         Subsidiaries, and each of the Company's, the Parent's and their
         Subsidiaries' consultants has executed an agreement regarding
         confidentiality and proprietary information and, to the knowledge of
         the Company, none of such employees and consultants are in violation of
         such agreements. Schedule 5(z) lists all Owned Intellectual Property
         which has been duly registered with, filed in or issued by, as the case
         may be, the United States Patent and Trademark Office and United States
         Copyright Office or other filing offices, domestic or foreign, and
         identifies the office with which such filing was made. Each Owned
         Intellectual Property registration and filing listed in Schedule 5(z)
         is in full force and effect.

                  (ii)     Schedule 5(z) sets forth a complete and correct list
         of all material Contractual Obligations (A) pursuant to which the use
         by any Person of Intellectual Property is licensed or permitted by the
         Company, the Parent or any of their Subsidiaries and (B) pursuant to
         which the use by the Company, the Parent or any of their Subsidiaries
         of Intellectual Property is licensed or permitted by any other Person
         (collectively, the "Intellectual Property Licenses"). All Intellectual
         Property Licenses (A) are in full force and effect in accordance with
         their terms, and (B) are free and clear of any Liens (other than
         Permitted Liens). Neither the Company, the Parent nor any of their
         Subsidiaries nor, to the Company's best knowledge, any of the other
         Parties thereto is in default under any of the Intellectual Property
         Licenses, and no such default is currently threatened. There is no
         claim or demand of any Person pertaining to, or any proceeding which is
         pending or, to the best knowledge of the Company, threatened, that
         challenges the rights of the Company, the Parent or any of their
         Subsidiaries in respect of

                                       23
<PAGE>   29

         any Intellectual Property, Owned Intellectual Property or any of the
         Intellectual Property Licenses. None of the Owned Intellectual Property
         or any Intellectual Property Licenses are subject to any outstanding
         order, ruling, decree, judgment or stipulation by or with any court,
         tribunal, arbitrator or other Governmental Authority. The Company has
         taken commercially reasonable steps to maintain and protect its trade
         secrets. To the Company's knowledge, any Person licensing Intellectual
         Property from the Company has taken all commercially reasonable steps
         to maintain and protect the Intellectual Property which is subject to
         such license.

         (aa)     Absence of Certain Changes or Events. Except as set forth in
Schedule 5(aa), since the date of the Latest Balance Sheet, the Company, the
Parent and each of their Subsidiaries has conducted its business only in the
ordinary course consistent with its past practices, and neither the Company, the
Parent nor any of their Subsidiaries has (i) incurred, or agreed to incur,
Indebtedness, (ii) experienced any damage, destruction or loss that, to the
extent not covered by insurance, has had or reasonably would be expected to have
a Material Adverse Effect, (iii) declared, set aside or paid any dividend or
other distribution (whether in cash, equity securities, interests or property)
in respect of its equity securities, (iv) entered into any material Contractual
Obligation involving any director, officer, manager, shareholder, member,
employee, Affiliate or their respective Affiliates or Related Parties of the
Company, the Parent or any of their Subsidiaries, (v) granted or committed to
grant to any director, officer, manager, member, employee or Affiliate of the
Company, the Parent or any of their Subsidiaries any material increase in
compensation or benefits, (vi) granted or committed to grant to any director,
officer, manager, employee or Affiliate of the Company, the Parent or any of
their Subsidiaries any increase in or right to severance or termination pay or
any other compensation or benefits payable upon a change in control of any such
entity or (vii) taken any action that, if taken after the Closing Date hereof,
reasonably would be expected to constitute a breach of any of the covenants set
forth in Section 7.

         (bb)     Insurance. Schedule 5(bb) sets forth a true and complete
summary of all insurance policies or arrangements carried or maintained by the
Company as of the Closing Date, indicating in each case the insurer, policy
number, expiration, amount and type of coverage and deductibles. The assets,
properties and business of the Company, the Parent and their Subsidiaries are
insured against such hazards and liabilities, under such coverages and in such
amounts, as are customarily maintained by prudent companies similarly situated
and under policies issued by insurers of recognized responsibility.

SECTION 6. REPRESENTATIONS AND WARRANTIES OF THE PURCHASER. The Purchaser
represents and warrants to the Company as follows:

         (a)      It is an "accredited investor" as that term is defined in Rule
501 of the Securities Act, and that, in making the purchases contemplated
herein, it is specifically understood and agreed that the Purchaser is acquiring
the Note for the purpose of investment and not with a view towards the sale or
distribution thereof within the meaning of the Securities Act; provided,
however, that the disposition of the Purchaser's property shall at all times be
and remain within its control.

                                       24
<PAGE>   30

         (b)      It understands that the Note will not be registered under the
Securities Act, by reason of their issuance by the Company in a transaction
exempt from the registration requirements of the Securities Act, and that it
must hold the Note indefinitely unless a subsequent disposition thereof is
registered under the Securities Act and applicable state securities laws or is
exempt from registration.

         (c)      It understands that the exemption from registration afforded
by Rule 144 (the provisions of which are known to the Purchaser) promulgated by
the Commission under the Securities Act depends on the satisfaction of various
conditions, including the requirement that the Company has been subject to the
reporting requirements of Section 13 or Section 15 of the Exchange Act for at
least 90 days, and that, if applicable, Rule 144 affords the basis for sales
only in limited amounts and that the Company does not now qualify under Rule 144
and may not ever qualify.

         (d)      It has not employed any broker or finder in connection with
the transactions contemplated by this Agreement.

         (e)      It has been furnished with or has had access to the
information it has requested from the Company and the Parent and has had an
opportunity to discuss with the management of the Company and the Parent the
business and financial affairs of the Company, the Parent and their
Subsidiaries, and has generally such knowledge and experience in business and
financial matters and with respect to investments in securities or privately
held companies so as to enable it to understand and evaluate the risks of such
investment and form an investment decision with respect thereto; provided,
however, that the foregoing shall in no way affect, diminish or derogate from
the representations and warranties made by the Company hereunder or the right of
the Purchaser to rely thereon and to seek indemnification hereunder.

         (f)      The execution and delivery of this Agreement and the other
Transaction Documents to which it is a party have been duly authorized by all
necessary action of the Purchaser, do not conflict with or result in a breach of
any of the Purchaser's governing documents or any Contractual Obligation or any
Requirement of Law and constitute legal, valid and binding agreements of the
Purchaser enforceable against it in accordance with their respective terms
except as enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, arrangement, moratorium, fraudulent conveyance or other similar
laws of general applicability relating to or affecting the enforcement of
creditors' rights generally or by general equitable principles.

SECTION 7. COVENANTS. The Company covenants and agrees, that until the payment
in full of all principal and interest under the Note together with all
Obligations and all amounts then due and owing under the other Transaction
Documents:

         (a)      Payment of Notes. The Company will duly and punctually pay the
principal of, and interest and any premium on, any Note when the same becomes
due and payable (whether by scheduled maturity, required prepayment,
acceleration or otherwise pursuant to the terms of the Note), subject to
applicable grace periods.

                                       25
<PAGE>   31

         (b)      Financial Statements. The Company will deliver to the
Purchaser:

                  together with a written statement of a Responsible Officer of
                  the Company setting forth the nature and period of existence
                  thereof and the action that the Company has taken and proposes
                  to take with respect thereto;

Parent and each of their Subsidiaries to, (i) pay all liabilities and

and memoranda of them, and to discuss its affairs, finances and accounts with
its officers and employees and, upon notice to the Company, the independent

         defend and indemnify the Purchaser and its officers, directors,
         managers, employees, attorneys and agents (each, an "Indemnified
         Party") against, and hold each Indemnified Party harmless from, all
         losses, claims, damages, liabilities, costs (including the costs of
         preparation and actual attorneys' fees and expenses reasonably
         incurred) (collectively, the "Losses") incurred by any Indemnified
         Party as a result of, or arising out of, or relating to (A) any
         misrepresentation or breach of any representation or warranty made by
         the Company herein, (B) any breach of any covenant, agreement or
         obligation of the Company, the Parent or any of their Subsidiaries
         contained in any of the Transaction Documents or (C) any investigation
         or proceeding against the Company or any Indemnified Party and arising
         out of or in connection with this Agreement or any of the Transaction
         Documents, whether or not the transactions contemplated by this
         Agreement are consummated, which investigation or proceeding requires
         the participation of, or is commenced or filed against, any Indemnified
         Party because of this Agreement, any other Transaction Document or such
         other documents and the transactions contemplated hereby or thereby,
         other than any Losses resulting from action on the part of such
         Indemnified Party which is finally determined in such proceeding to be
         primarily and directly a result of such party's gross negligence or
         willful misconduct. The Company agrees to reimburse each Indemnified
         Party promptly for all such Losses as they are incurred by such
         Indemnified Party in connection with the investigation of, preparation
         for or defense of any pending or threatened claim or any action or
         proceeding arising therefrom. The Purchaser agrees to reimburse the
         Company for any payments made by the Company to the Purchaser pursuant
         to this paragraph for Losses which are finally determined in such
         proceeding to primarily and

                                       31
<PAGE>   37

         directly result from the gross negligence or willful misconduct of the
         Purchaser. The obligations of the Company under this paragraph will
         survive any transfer of the Note, or the Capital Stock issued pursuant
         to the Acquisition Documents by the Purchaser and the termination of
         this Agreement. In the event that the foregoing indemnity is
         unavailable or insufficient to hold an Indemnified Party harmless, then
         the Company will contribute to amounts paid or payable by such
         Indemnified Party in respect of such Indemnified Party's Losses in such
         proportions as appropriately reflect the relative benefits received by
         and fault of the Company and such Indemnified Party in connection with
         the matters as to which such Losses relate and other equitable
         considerations.

                  (ii)     If any action, proceeding or investigation is
         commenced, as to which any Indemnified Party proposes to demand such
         indemnification, it shall notify the Company with reasonable
         promptness; provided, however, that any failure by such Indemnified
         Party to notify the Company shall not relieve the Company from its
         obligations hereunder except to the extent the Company is prejudiced
         thereby. The Company shall be entitled to assume the defense of any
         such action, proceeding or investigation, including the employment of
         counsel and the payment of all fees and expenses. The Indemnified Party
         shall have the right to employ separate counsel in connection with any
         such action, proceeding or investigation and to participate in the
         defense thereof, but the fees and expenses of such counsel shall be
         paid by the Indemnified Party, unless (A) the Company has failed to
         assume the defense and employ counsel as provided herein, (B) the
         Company has agreed in writing to pay such fees and expenses of separate
         counsel or (C) an action, proceeding, or investigation has been
         commenced against both the Indemnified Party and/or the Company and
         representation of both the Company and the Indemnified Party by the
         same counsel would be inappropriate because of actual or potential
         conflicts of interest between the parties. In the case of any
         circumstance described in clauses (A), (B) or (C) of the immediately
         preceding sentence, the Company shall be responsible for the reasonable
         fees and expenses of such separate counsel actually incurred; provided,
         however, that the Company shall not in any event be required to pay the
         fees and expenses of more than one separate counsel (and, if deemed

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE OR INSTRUMENT HAVE NOT
         BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY
         STATE SECURITIES LAWS, AND MAY NOT BE TRANSFERRED UNLESS THE COMPANY

         SATISFACTORY TO THE COMPANY STATING THAT SUCH TRANSFER IS BEING MADE IN
         COMPLIANCE WITH ALL APPLICABLE FEDERAL AND STATE SECURITIES LAWS.

         (k)      Confidentiality; Public Announcements.

                  (i)      The Purchaser shall use its best efforts not to make
         public disclosure of any information designated by the Company in
         writing as confidential, including financial terms and financial and
         organizational information contained in any documents, statements,
         certificates, materials or information furnished, or to be furnished,
         by the Company in connection with the transactions contemplated by this
         Agreement; provided, however, that the foregoing shall not be
         construed, now or in the future, to apply to any information reflected
         in any recorded document, information which is independently developed
         by the Purchaser, information obtained from sources other than the
         Company or information that is or becomes in the public domain, nor
         shall it be construed to prevent the Purchaser from (i) making any
         disclosure of any information (A) if required to do so by any
         Requirement of Law, (B) to any Governmental Authority having or
         claiming authority to regulate or oversee any aspect of the Purchaser's
         business or that of the corporate parent or affiliates of the Purchaser
         in connection with the exercise of such authority or claimed authority,
         or (C) pursuant to subpoena; or (ii) to the extent the Purchaser or its
         counsel deems necessary or appropriate to do so to effect or preserve
         its security for any applicable investment or financing or to enforce
         any remedy provided herein or in any applicable investment or financing
         documents or otherwise available by law; or (iii) making, on a
         confidential basis, such disclosures as the Purchaser

                                       41
<PAGE>   47

         deems necessary or appropriate to such Purchaser's legal counsel or
         accountants (including outside auditors); or (iv) making such
         disclosures as the Purchaser reasonably deems necessary or appropriate
         to any bank or financial institution or other entity, and/or counsel to
         or other representatives of such bank or financial institution or other
         entity, to which the Purchaser in good faith desires to sell an
         interest in any applicable investment or financing; provided, however,
         that such bank, financial institution or other entity or counsel to or
         representative thereof, agrees to take reasonable steps to maintain the
         confidentiality of such disclosures.

                  (ii)     The Purchaser shall have the right to review and
         approve, such approval not to be unreasonably withheld, any public
         announcement or public filing made after the Closing Date relating to
         the Note or to the Purchaser in any way before any such announcement or
         filing is announced or filed, provided, however, no review or approval
         shall be required for any such announcement or filing required to be
         announced or filed by law. In addition, the Purchaser shall provide the
         Company an opportunity to review and approve any public announcement
         issued by the Purchaser specifically relating to the Note, such
         approval not to be unreasonably withheld or delayed; provided, however,
         no review or approval shall be required for any such announcement
         required to be announced by law; provided further, the Purchaser shall
         provide the Company with an advance copy of any regulatory filings or
         tombstone ads prepared by or on behalf of the Purchaser, but shall not
         be required to obtain approval by the Company.

         (l)      Governing Law. This Agreement shall be governed in all
respects by the laws of the State of North Carolina.

         (m)      Headings. The descriptive section headings herein have been
inserted for convenience only and shall not be deemed to limit or otherwise
affect the construction of any provisions hereof.

         (n)      Multiple Originals. This Agreement may be executed
simultaneously in two or more counterparts, each of which shall be deemed an
original, and it shall not be necessary in making proof of this Agreement to
produce or account for more than one such counterpart.

         (o)      Amendment or Waiver. This Agreement may be amended, and the
Company may take any action herein prohibited, or omit to perform any act herein
required to be performed by it, if the Company shall obtain the prior written
consent of the Required Purchasers to such amendment, action or omission to act;
provided, however, that, without the prior written consent of each of the
Purchasers, no such agreement shall (i) decrease the principal amount of, or
extend the maturity date of any Note, or decrease the rate of interest on the
Note, without the prior written consent of each Purchaser affected thereby, (ii)
effect any waiver, amendment or modification that by its terms changes the
amount, allocation, payment of or between the Note, or (iii) amend the
provisions of this Section 11(o), the definition of the term "Required
Purchasers" or of the term "Note". Each holder of the Note, at the time or times
thereafter outstanding, shall be bound by any consent authorized by this
Section, whether or not the Note shall have been marked to indicate such
consent.

         (p)      Waiver of Jury Trial. THE PURCHASER AND THE COMPANY EACH
HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE (TO THE EXTENT PERMITTED
BY APPLICABLE LAW) ANY RIGHT TO A TRIAL BY JURY OF ANY DISPUTE ARISING UNDER,
RELATING TO, OR CONNECTED WITH THIS AGREEMENT, THE COLLATERAL OR ANY OTHER
AGREEMENT, INSTRUMENT OR DOCUMENT CONTEMPLATED HEREBY OR DELIVER IN CONNECTION
HEREWITH AND AGREE THAT ANY SUCH DISPUTE SHALL BE TRIED BEFORE A JUDGE SITTING
WITHOUT A JURY. THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE PARTIES TO ENTER
INTO THIS AGREEMENT.

         (q)      Consent to Jurisdiction and Service of Process. All judicial
proceedings brought against the Company with respect to this Agreement, the Note
or any of the other Transaction Documents may be brought in any state or federal
court of competent jurisdiction in the State of North Carolina, and, by
execution and delivery of this Agreement, the Company accepts, for itself and in
connection with its properties, generally and unconditionally, the non-exclusive
jurisdiction of the aforesaid courts and irrevocably agrees to be bound by any
final judgment rendered thereby in connection with this Agreement from which no
appeal has been taken or is available. The Company irrevocably agrees that all
service of process in any such proceedings in any such court may be effected by
mailing a copy thereof by registered or certified mail (or any substantially
similar form of mail), postage prepaid, to it at its address set forth in
Schedule 11(i) or at such other address of which the Purchaser shall have been
notified pursuant thereto, such service being hereby acknowledged by the Company
to be effective and binding service in every respect. Each of the parties hereto
irrevocably waives any objection, including, without limitation, any objection
to the laying of venue or based on the grounds of forum non conveniens which it
may now or hereafter have to the bringing of any such action or proceeding in
any such jurisdiction. Nothing herein shall affect the right to serve process in
any other manner permitted by law or shall limit the right of the Purchaser to
bring proceedings against the Company in the court of any other jurisdiction.

         (r)      Arbitration.

                  (i)      Notwithstanding the provisions of Section 11(q) to
         the contrary, upon demand of any party hereto, whether made before or
         within three months after institution of any judicial proceeding, any
         dispute, claim or controversy arising out of, connected with or
         relating to this Agreement and other Transaction Documents ("Disputes")
         between or among parties to this Agreement shall be resolved by binding
         arbitration as provided herein. Institution of a judicial proceeding by
         a party does not waive the right of that party to demand arbitration
         hereunder. Disputes may include, without limitation, tort claims,
         counterclaims, disputes as to whether a matter is subject to
         arbitration, claims brought as class actions, claims arising from
         Transaction Documents executed in the future, or claims arising out of
         or connected with the transactions reflected by this Agreement.
         Arbitration shall be conducted under and governed by the Commercial
         Arbitration Rules (the "Arbitration Rules") of the American Arbitration
         Association (the "AAA") and Title 9 of the U.S. Code. All arbitration
         hearings shall be conducted in Charlotte, North Carolina. A hearing
         shall begin within 90 days of demand for

                                       43
<PAGE>   49

         arbitration, and all hearings shall be concluded within 120 days of
         demand for arbitration. These time limitations may not be extended
         unless a party shows cause for extension and then no more than a total
         extension of 60 days. The expedited procedures set forth in Rule 51 et
         seq. of the Arbitration Rules shall be applicable to claims of less
         than $1,000,000. All applicable statutes of limitation shall apply to
         any Dispute. A judgment upon the award may be entered in any court
         having jurisdiction. Arbitrators shall be licensed attorneys selected
         from the Commercial Financial Dispute Arbitration Panel of the AAA. The
         parties hereto do not waive applicable federal or state substantive law
         except as provided herein.

                  (ii)     Notwithstanding the preceding binding arbitration
         provisions, each of the parties agrees to preserve, without diminution,
         certain remedies that the Purchaser may employ or exercise freely,
         independently or in connection with an arbitration proceeding or after
         an arbitration action is brought. The Purchaser shall have the right to
         proceed in any court of proper jurisdiction or by self-help to exercise
         or prosecute the following remedies, as applicable (A) all rights to
         foreclose against any real or personal property or other security by
         exercising a power of sale granted under Transaction Documents or under
         applicable law or by judicial foreclosure and sale, including a
         proceeding to confirm the sale; (B) all rights of self-help including
         peaceful occupation of real property and collection of rents, set-off,
         and peaceful possession of personal property; (C) obtaining provisional
         or ancillary remedies including injunctive relief, sequestration,
         garnishment, attachment, appointment of receiver and filing an
         involuntary bankruptcy proceeding; and (D) when applicable, a judgment
         by confession of judgment. Preservation of these remedies does not
         limit the power of an arbitrator to grant similar remedies that may be
         requested by a party in a Dispute.

                  (iii)    The parties hereto agree that they shall not have a
         remedy of punitive or exemplary damages against the other in any
         Dispute and hereby waive any right or claim to punitive or exemplary
         damages against the other in any Dispute and hereby waive any right or
         claim to punitive or exemplary damages they have now or which may arise
         in the future in connection with any Dispute whether the Dispute is
         resolved by arbitration or judicially.

                  (iv)     By execution and delivery of this Agreement, each of
         the parties hereto accepts, for itself and in connection with its
         properties, generally and unconditionally, the non-exclusive
         jurisdiction relating to any arbitration proceedings conducted under
         the Arbitration Rules in Charlotte, North Carolina and irrevocably
         agrees to be bound by any final judgment rendered thereby in connection
         with this Agreement from which no appeal has been taken or is
         available.

         (s)      Parent Covenants; Parent Representations. For purposes of
         Sections 7 and 9 of this Agreement, it is understood and agreed that
         the Company shall use commercially reasonable efforts to cause the
         Parent to comply with the terms thereof. For purposes of Section 5, all
         representations and warranties as to the Parent by the Company shall be
         deemed to be made to the knowledge of the Company.

         (t)      Authorization of Motorola Transactions. The Company is
         authorized to enter into reimbursement, service acquisitions and/or
         purchase transactions with Motorola with respect to the Company's
         acquisition of new telecom network equipment products.
