SECTION 2.10. MAXIMUM LAWFUL INTEREST RATE. Notwithstanding any
provision contained herein, the total liability of the Borrowers for payment of

amounts, to the extent such charges and other amounts are deemed to be interest,
shall not exceed the maximum amount of such interest permitted by law to be
charged, collected, or received from the Borrowers (the "MAXIMUM RATE"). If any
payments by either Borrower include interest in excess of the Maximum Rate,

Lender shall apply such excess to the reduction of the unpaid principal amount
owing by such Borrower, or if none is due, such excess shall be returned to such
Borrower.

SECTION 2.11. INCREASED CAPITAL. If the Lender or any Participant
which is subject to minimum capital requirements determines that compliance by
such Person, with any guideline or request from any central bank or other
Governmental Authority (whether or not having the force of law) affects or would

Person, or any corporation controlling such Person, and such Person reasonably
determines that the amount of such capital is increased by or based upon any
commitment to lend hereunder or under the Participation Agreement or making or
maintaining Loans, and other commitments of this type, then, upon demand by such
Person, the Borrowers agree to, within three (3) days of such demand, pay to
such Person, from time to time as specified by such Person, additional amounts
sufficient to compensate such Person in the light of such circumstances, to the
extent that such Person reasonably determines such increase in capital to be
allocable to such Person's commitment or maintenance of Loans hereunder or
pursuant to the Participation Agreement. A certificate as to the amount of such
increased cost, submitted to the Borrowers by the applicable Person shall,
absent manifest error, be conclusive and binding on the Borrowers for all
purposes.

SECTION 2.12. JOINT AND SEVERAL LIABILITY; CONTRIBUTION. (a)
Notwithstanding anything to the contrary in this Agreement or the other Loan
Documents but subject to the provisions of SECTION 2.07(F), all payment and
performance Obligations arising under this Agreement and the other Loan
Documents shall be joint and several obligations of each Borrower secured by all
the Borrowers' Collateral. Lender may apply any portion of any Borrower's
Collateral to satisfy any of the Obligations of any other Borrower.

(b) CONTRIBUTION AND INDEMNIFICATION BETWEEN THE BORROWERS. To the
extent that either Borrower shall, as a result of the operation of SECTION 2.12,
pay any Obligation of the other Borrower under the Loan Documents (such payment
being referred to as an "Accommodation Payment"), then such Borrower shall be
entitled to contribution and indemnification from, and be reimbursed by the
other Borrower, equal to a fraction of such Accommodation Payment, the numerator
of which fraction is such other Borrower's "Allocable Amount" (as defined below)
and the denominator of which is the sum of the Allocable Amounts of both the
Borrowers. As of any date of determination, the "Allocable Amount" of each
Borrower shall be equal to the maximum amount of liability for Accommodation
Payments which could be asserted against such Borrower hereunder without (a)
rendering such Borrower "insolvent" within the meaning of Section 101(31) of the
Bankruptcy Code , Section 2 of the Uniform Fraudulent Transfer Act (the "UFTA")
or Section 2 of the Uniform Fraudulent Conveyance Act (the "UFCA"), (ii) leaving
such Borrower with unreasonably small capital or assets, within the meaning of
Section 548 of the Bankruptcy Code, Section 4 of the UFTA, or Section 5 of the
UFCA, or (iii) leaving such Borrower unable to pay its debts as they become due
within the meaning of Section 548 of the Bankruptcy Code or Section 4 of the
UFTA, or Section 5 of the UFCA. All rights and claims of contribution,
indemnification and reimbursement under this section shall be subordinate in
right of payment to the prior payment in full of the Obligations. The
provisions of this section shall, to the

extent expressly inconsistent with any provision in any Loan Document, supersede
such inconsistent provision.

issuance of such order, and, in the case of any other order revoking or
terminating any of the Governmental Approvals or deciding not to renew such
Governmental Approvals prior to the termination thereof, occur when such order

(j) the FCC, any PUC or any other Governmental Authority, by final
order, determines that the existence or performance of this Agreement or any
other Loan Document will result in a revocation, suspension or material adverse
modification of any of the Governmental Approvals for any System of KMC; or

(k) for any reason any Loan Document shall not be in full force and
effect or shall not be enforceable in accordance with its terms, or any security
interest or lien granted pursuant thereto shall fail to be perfected or to have
its intended priority, or any party thereto other than Lender shall contest the
validity of any lien granted under, or shall disaffirm its obligations under any
Loan Document; or

(l) either Borrower shall have wrongfully failed to accept Equipment
in accordance with any Lucent Purchase Agreement or Additional Purchase
Agreement within the period specified in such Lucent Purchase Agreement or
Additional Purchase Agreement or shall otherwise default under any Lucent

have been cured or waived within the applicable grace period thereunder; or

(m) for any reason, either Borrower ceases to operate its Business or

violation of any environmental, health or safety requirement of law; or

(q) a Change of Control shall occur and either Borrower shall have
failed to comply with the provisions of SECTION 2.07(B) if requested to do so by
the Lender.

SECTION 9.02. TERMINATION OF COMMITMENT; ACCELERATION. Upon the
occurrence and at any time during the continuance of any Event of Default:

(a) Lender may by notice to the Borrowers, terminate Lender's
Commitment to make Loans hereunder;

(b) Lender may by notice to the Borrowers, declare the Obligations
to be immediately due and payable, whereupon all the Obligations shall be
immediately due and payable without further notice of any kind, PROVIDED,
HOWEVER, that if an Event of Default described in SECTION 9.01(F) shall exist or
occur, all of the Obligations shall automatically, without declaration or notice
of any kind, be immediately due and payable and the Commitment shall be
automatically terminated; and

(c) a Participant may, pursuant to the terms of the Participation
Agreement if such Event of Default has been declared by Lender or notice thereof
provided to Borrowers by Lender, upon notice to the Lender, the Borrowers and
the other Participants, terminate its obligation to purchase Participations, in
which case a portion of the Commitment equal to the Participation Share of such
Participant shall automatically terminate.

SECTION 9.03. WAIVER. Demand, presentment, protest and notice of
nonpayment are hereby waived by the Borrowers. The Borrowers also waive the
benefit of all valuation, appraisal and exemption laws and the posting of any
bond required of Lender in connection with any judicial process to realize on
the Collateral, to enforce any judgment or other court order entered in favor of
Lender or to enforce by specific performance, temporary restraining order, or
preliminary or permanent injunction, this Agreement or any other Loan Documents.
The Borrowers hereby acknowledge that Lender has no obligation to resort to any
collateral or make claim against any other Person before seeking payment or
performance from either Borrower.

SECTION 9.04. RIGHTS AND REMEDIES GENERALLY. If an Event of Default
occurs and is continuing, Lender shall have, in addition to any other rights and
remedies contained in this Agreement or in any of the other Loan Documents, all
of the rights and remedies of a secured party under the Code or other applicable
laws, all of which rights and remedies shall be cumulative, and none exclusive,
to the extent permitted by law. In addition to all such rights and remedies,
the sale, lease or other disposition of the Collateral, or any part thereof, by
Lender after the occurrence of an Event of Default may be for cash, credit or
any combination thereof, and

Lender may purchase all or any part of the Collateral at public or, if permitted
by law, private sale, and in lieu of actual payment of such purchase price, may
set off the amount of such purchase price against the Obligations then owing.
Any sales of the Collateral may be adjourned from time to time with or without
notice. Lender may, in its sole discretion, cause the Collateral to remain on
the premises of either Borrower, at the expense of the Borrowers, pending sale
or other disposition of the Collateral. Lender shall have the right to conduct
such sales on the premises of either Borrower, at the expense of the Borrowers,
or elsewhere, on such occasion or occasions as Lender may see fit.

SECTION 9.05. ENTRY UPON PREMISES AND ACCESS TO INFORMATION. If an
Event of Default occurs and is continuing, Lender shall have the right to enter
upon the premises of either Borrower where any Collateral is located (or is
believed to be located) without any obligation to pay rent to such Borrower, or
any other place or places where the Collateral is believed to be located and
kept, and render the Collateral unusable or remove the Collateral therefrom to
the premises of Lender or any agent of Lender, for such time as Lender may
desire, in order effectively to collect or liquidate the Collateral, and/or
Lender may require either Borrower to assemble the Collateral and make it
available to Lender at a place or places to be designated by Lender. If an
Event of Default occurs and is continuing, Lender shall have the right to obtain
access to either Borrower's data processing equipment, computer hardware and
software relating to the Collateral and to use all of the foregoing and the
information contained therein in any manner Lender deems appropriate.

SECTION 9.06. SALE OR OTHER DISPOSITION OF COLLATERAL BY LENDER. Any
notice required to be given by Lender of a sale, lease or other disposition or
other intended action by Lender with respect to any of the Collateral which is
deposited in the United States mails, registered or certified, postage prepaid
and duly addressed to the Borrowers at the address specified in SECTION 10.01
below, at least ten days prior to such proposed action shall constitute fair and
reasonable notice to the Borrowers of any such action. The net proceeds
realized by Lender upon any such sale or other disposition, after deduction for
the expense of retaking, holding, preparing for sale, selling or the like and
the reasonable attorneys' fees and legal expenses incurred by Lender in
connection therewith, shall be applied as provided herein toward satisfaction of
the Obligations. Lender shall account to the Borrowers for any surplus realized
upon such sale or other disposition, and the Borrowers shall remain liable for
any deficiency. The commencement of any action, legal or equitable, or the
rendering of any judgment or decree for any deficiency shall not affect Lender's
security interest in the Collateral. The Borrowers agree that Lender has no
obligation to preserve rights to the Collateral against any other parties.
Lender is hereby granted a license or other right to use, without charge, the
Borrowers' labels, patents, copyrights, rights of use of any name, trade
secrets, trade names, trademarks, service marks and advertising matter, or any
property of a similar nature, as it pertains to the Collateral, and the
Borrowers' rights under all licenses and all franchise agreements shall inure to
Lender's benefit until the Obligations are paid in full.

SECTION 9.07. GOVERNMENTAL APPROVALS. In connection with the
enforcement by Lender of any remedies available to it as a result of any Event
of Default, each Borrower agrees that it shall join and cooperate fully with, at
the request of Lender, any receiver referred to

below and/or the successful bidder or bidders at any foreclosure sale in a
filing of an application (and furnishing any additional information that may be
required in connection with such application or which Lender may believe
relevant to such application) with the FCC, any PUC and all other applicable
Governmental Authorities, requesting their prior approval of (i) the operation
or abandonment of all or the portion of any System and/or (ii) the transfer of
control of such Borrower or assignment of all licenses, certificates,
Governmental Approvals, approvals and permits, issued to such Borrower by the
FCC, any PUC or any such Governmental Authorities with respect to any System and
the operation thereof, to Lender, the receiver or to the successful bidder or
bidders. In connection with the foregoing, each Borrower shall take such
further actions, and execute all such instruments, as Lender reasonably deems
necessary or desirable. Each Borrower agrees that Lender may enforce any
obligation of such Borrower as set forth in this section by an action for
specific performance. In addition, each Borrower hereby irrevocably constitutes
and appoints Lender and any agent or officer thereof (which appointment is
coupled with an interest) as its true and lawful attorney-in-fact with full
irrevocable power and authority and in the place and stead of such Borrower and
in the name of such Borrower or in its own name, from time to time in its
discretion after the occurrence and during the continuance of an Event of
Default and in connection with the foregoing, for the purpose of executing on
behalf and in the name of such Borrower any and all of the above-referenced
instruments and to take any and all appropriate action in furtherance of the
foregoing. THE EXERCISE OF ANY RIGHTS OR REMEDIES HEREUNDER OR UNDER ANY OTHER
LOAN DOCUMENT BY LENDER THAT MAY REQUIRE FCC, ANY PUC OR ANY OTHER GOVERNMENTAL
AUTHORITY APPROVAL SHALL BE SUBJECT TO OBTAINING SUCH APPROVAL. PENDING THE
RECEIPT OF ANY FCC, ANY PUC OR ANY OTHER GOVERNMENTAL AUTHORITY APPROVAL,
NEITHER BORROWER SHALL DO ANYTHING TO DELAY, HINDER, INTERFERE OR OBSTRUCT THE
EXERCISE OF LENDER'S RIGHTS OR REMEDIES HEREUNDER IN OBTAINING SUCH APPROVALS.

SECTION 9.08. APPOINTMENT OF RECEIVER OR TRUSTEE. In connection with
the exercise of its remedies under this Agreement, Lender may, upon the
occurrence of an Event of Default, obtain the appointment of a receiver or
trustee to assume, upon receipt of all necessary judicial, FCC, any PUC or other
Governmental Authority consents or approvals, control of or ownership of any of
the Governmental Approvals. Such receiver or trustee shall have all rights and
powers provided to it by law or by court order or provided to Lender under this
Agreement. Upon the appointment of such trustee or receiver, the Borrowers
agree to cooperate, to the extent necessary or appropriate, in the expeditious
preparation, execution and filing of an application to the FCC any PUC or any
other Governmental Authority or for consent to the transfer of control or
assignment of either Borrower's Governmental Approvals to the receiver or
trustee.

SECTION 9.09. RIGHT OF SETOFF. In addition to any rights and
remedies of Lender provided by law, Lender shall have the right, without prior
notice to the Borrowers, upon the occurrence of an Event of Default, to setoff
and apply against the amount of any Obligation, whether matured or unmatured,
any amount owing from Lender or any affiliate of Lender to either Borrower, or
any of either Borrower's Affiliates. Lender agrees promptly to notify the
Borrowers after any such setoff and application made by Lender or any affiliate
of Lender; PROVIDED that the failure to give such notice shall not affect the
validity of such setoff and application. The Borrowers hereby agree that the
foregoing provisions are intended to be

construed so as to satisfy the requirements of Section 553 of the Federal
Bankruptcy Code or amendments thereto (including any requirement of mutuality of
obligations therein).

Lender to be genuine, that Lender may consult with legal counsel, selected by
Lender and shall not be liable to either Borrower for any action taken or
omitted to be taken in good faith by Lender in accordance with the advice of
such counsel.

SECTION 10.02. NO WAIVERS; AMENDMENTS. (a) No failure or delay of
Lender to exercise any right hereunder or under any other Loan Document shall
operate as a waiver thereof, nor shall any single or partial exercise of any
such right, preclude any other or further exercise thereof or the exercise of
any other right. No waiver of any provision of this Agreement or any other Loan
Document nor consent to any departure by either Borrower therefrom shall in any
event be effective unless the same shall be in writing and signed by Lender, and
then such waiver or consent shall be effective only in the specific instance and
for the purpose for which given. No notice or demand on either Borrower in any
case shall entitle either Borrower to any other or further notice or demand in
similar or other circumstances. Each of the Borrowers acknowledges and agrees
that no failure or delay of Lender to exercise any right under the Original
Agreement shall operate as a waiver hereunder and no course of dealing under the

Original Agreement that constituted a departure from the terms and provisions
thereof shall have any effect under this Agreement.

(b) This Agreement may not be amended or modified except pursuant to
an agreement or agreements in writing executed by the Borrowers and Lender.

SECTION 10.03. GOVERNING LAW AND JURISDICTION. THIS AGREEMENT AND
THE OTHER LOAN DOCUMENTS SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY
THE INTERNAL LAWS OF THE STATE OF NEW JERSEY WITHOUT GIVING EFFECT TO ANY
CONFLICTS OF LAWS PRINCIPLES. THE BORROWERS AND LENDER CONSENT TO THE
JURISDICTION OF ANY LOCAL, STATE OR FEDERAL COURT LOCATED IN THE STATE OF NEW
JERSEY AND WAIVE ANY OBJECTION RELATING TO IMPROPER VENUE OR FORUM NON
CONVENIENS TO THE CONDUCT OF ANY PROCEEDING BY SUCH COURT.

SECTION 10.04. EXPENSES; DOCUMENTARY TAXES. The Borrowers will pay,
and have joint and several liability for, all documented out-of-pocket
third-party expenses (i) incurred by Lender and Participants in connection with
the negotiation, preparation and execution of the Loan Documents (whether or not
the transactions contemplated hereby shall be consummated), and (ii) by Lender
in connection with the administration of the Loan Documents, the creation,
perfection, priority and protection of the Liens in the Collateral, and the
enforcement of the rights of Lender in connection with this Agreement, any other
Loan Documents or the Collateral, including all reasonable attorneys' and
paralegals' fees and related expenses and costs. The Borrowers agree that they
shall jointly and severally indemnify Lender from and hold it harmless against
any documentary taxes, assessments or charges made by any Governmental Authority
by reason of the execution and delivery of this Agreement or any other Loan
Document unless prohibited by law.

SECTION 10.05. EQUITABLE RELIEF. Each Borrower recognizes that, in
the event such Borrower fails to perform, observe or discharge any of its
obligations or liabilities under this Agreement, or any other Loan Document, any
remedy at law may prove to be inadequate relief to Lender; therefore, such
Borrower agrees that Lender, if Lender so requests, shall be entitled to
temporary and permanent injunctive relief in any such case without the necessity
of proving actual damages.

SECTION 10.06. INDEMNIFICATION; LIMITATION OF LIABILITY. (a) The
Borrowers jointly and severally agree to protect, indemnify and hold harmless
Lender and each of its officers, affiliates, directors, employees, attorneys,
accountants, consultants, representatives, agents and Participants (collectively
called the "INDEMNITEES") from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, claims, costs, expenses
and disbursements (including, without limitation, payment by Lender of any
obligations due or past due under any contract or agreement to which either
Borrower is or becomes a party) of any kind or nature whatsoever (including,
without limitation, the fees and disbursements of counsel for and consultants of
such Indemnitees in connection with any investigative, administrative or
judicial proceeding, whether or not such Indemnitees shall be designated a party
thereto), which may be

imposed on, incurred by, or asserted against such Indemnitees (whether direct,
indirect, or consequential and whether based on any federal or state laws or
other statutory regulations, including, without limitation, securities,
environmental and commercial laws and regulations, under common law or at
equitable cause or on contract or otherwise) in any manner relating to or
arising out of this Agreement or any of the other Loan Documents, or any act,
event or transaction related or attendant thereto, the agreements of Lender
contained herein, the making of Loans, the management of such Loans or the
Collateral (including any liability under federal, state or local environmental
laws or regulations) or the use or intended use of the proceeds of such Loans
hereunder (collectively, the "INDEMNIFIED MATTERS"); PROVIDED that the Borrowers
shall not have any obligation to any Indemnitee hereunder with respect to
Indemnified Matters caused by or resulting from the willful misconduct or gross
negligence of such Indemnitee; PROVIDED, FURTHER that neither Borrower shall
have an obligation to any Indemnitee hereunder with respect to taxes that are
imposed on the net income of any Indemnitee or any franchise or doing business
taxes imposed on any Indemnitee. To the extent that the undertaking to
indemnify, pay and hold harmless set forth in the preceding sentence may be
unenforceable because it is violative of any law or public policy, the Borrowers
shall contribute the maximum portion which they are permitted to pay and satisfy
under applicable law, to the payment and satisfaction of all Indemnified Matters
incurred by the Indemnitees.

(b) To the extent permitted by applicable law, no claim may be made
by the Borrowers or any other Person against Lender or any of its affiliates,
directors, officers, employees, agents, attorneys, accountants, representatives,
consultants or Participants for any special, indirect, consequential or punitive
damages in respect of any claim for breach of contract or any other theory of
liability arising out of or related to the transactions contemplated by any of
the Loan Documents or any act, omission or event occurring in connection
therewith; and the Borrowers hereby waive, release and agree not to ▇▇▇ upon any
claim for any such damages, whether or not accrued and whether or not known or
suspected to exist in its favor.

SECTION 10.07. SURVIVAL OF REPRESENTATIONS AND WARRANTIES, ETC. All
warranties and representations made by either Borrower in any Loan Document
shall survive the execution and delivery of this Agreement and the other Loan
Documents and the making and repayment of the Obligations. The confidentiality
obligations of each Borrower in SECTION 10.16, the indemnification obligations
of each Borrower in SECTION 10.06, and to the extent the second sentence of
SECTION 10.13 is applicable, all covenants of each Borrower, survive the
repayment of the Obligations.

SECTION 10.08. SUCCESSORS AND ASSIGNS. (a) This Agreement shall be
binding upon and inure to the benefit of the Borrowers and Lender and their
respective successors and permitted assigns. Neither Borrower shall assign or
transfer any of its rights or obligations hereunder without the prior written
consent of Lender. Any such impermissible assignment or delegation shall be
void and of no force or effect. Without limiting the generality of the
foregoing, the Lender shall have the right to assign any of its rights hereunder
or delegate any of its obligations hereunder, in whole or in part and/or all of
its rights and interest under the Loan Documents as security therefor to any
affiliate, or to any bank, financial institution or financing company which in
the ordinary course of its business accepts assignments of loans or assumes

obligations to make loans from third parties, and in furtherance thereof to
provide to any such prospective or actual assignee financial or other
information relating to either Borrower, the Systems and the transactions
contemplated hereby.

(b) Without limiting the generality of the foregoing, the Lender
shall have the right in its sole discretion to sell one or more participations
in either Note and the Loan Documents without notice to or consent of either
Borrower to any affiliate, or to any bank, financial institution or financing
company which in the ordinary course of its business accepts assignments of
loans or assumes obligations to make loans from third parties, and in connection
therewith, to provide such participants with financial and other information and
copies of documents relating to the Borrowers, the Systems and the transactions
contemplated hereby. Upon receipt of written notice from Lender, the Borrowers
agree to provide to such participant(s) copies of all financial information
required to be delivered to the Lender pursuant to SECTION 5.06.

SECTION 10.09. SEVERABILITY. In case any one or more of the
provisions contained in this Agreement or any other Loan Document shall be
invalid, illegal or unenforceable in any respect, the validity, legality and
enforceability of the remaining provisions contained herein and therein shall
not in any way be affected or impaired thereby.

SECTION 10.10. COVER PAGE, TABLE OF CONTENTS AND SECTION HEADINGS.
The cover page, Table of Contents and section headings used herein are for
convenience of reference only, are not part of this Agreement and are not to
affect the construction of or be taken into consideration in interpreting this
Agreement.

SECTION 10.11. COUNTERPARTS. This Agreement may be signed in
counterparts with the same effect as if the signatures thereof and hereto were
upon the same instrument.

SECTION 10.12. APPLICATION OF PAYMENTS. Notwithstanding any contrary
provision contained in this Agreement or in any of the other Loan Documents,
upon the occurrence and during the continuance of any Event of Default, each
Borrower irrevocably waives the right to direct the application of any and all
payments at any time or times hereafter received by Lender from such Borrower or
with respect to any of the Collateral, and such Borrower does hereby irrevocably
agree that Lender shall have the continuing exclusive right to apply and reapply
any and all payments received at any time or times hereafter, whether with
respect to the Collateral or otherwise, against the Obligations in such manner
as Lender may deem advisable, notwithstanding any entry by Lender upon any of
its books and records.

SECTION 10.13. MARSHALLING; PAYMENTS SET ASIDE. Lender shall be
under no obligation to ▇▇▇▇▇▇▇▇ any assets in favor of either Borrower or any
other party or against or in payment of any or all of the Obligations. To the
extent that either Borrower makes a payment or payments to Lender or Lender
enforces its security interests or exercises its rights of setoff, and such
payment or payments or the proceeds of such enforcement or setoff or any part
thereof are subsequently invalidated, declared to be fraudulent or preferential,
set aside and/or required to be repaid to a trustee, receiver or any other party
under any bankruptcy law, state or federal law, common law or equitable cause,
then to the extent of such recovery, the obligation or part thereof

originally intended to be satisfied shall be revived and continued in full force
and effect as if such payment had not been made or such enforcement or setoff
had not occurred.

SECTION 10.14. SERVICE OF PROCESS. EACH BORROWER WAIVES PERSONAL
SERVICE OF ANY PROCESS UPON IT AND, CONSENTS THAT ALL SERVICE OF PROCESS SHALL
BE MADE BY REGISTERED MAIL, RETURN RECEIPT REQUESTED, DIRECTED TO SUCH BORROWER
AT THE ADDRESS INDICATED IN SECTION 10.01 AND SERVICE SO MADE SHALL BE DEEMED TO
BE COMPLETED FIVE (5) BUSINESS DAYS AFTER SAME SHALL HAVE BEEN POSTED AS
AFORESAID.

SECTION 10.15. WAIVER OF JURY TRIAL, ETC. EACH OF THE BORROWERS AND
LENDER WAIVES ANY RIGHT TO HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE,
WHETHER SOUNDING IN CONTRACT, TORT, OR OTHERWISE, BETWEEN LENDER AND EITHER
BORROWER ARISING OUT OF, CONNECTED WITH, RELATED TO OR INCIDENTAL TO THE
RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT OR ANY
OTHER LOAN DOCUMENT OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR
DELIVERED IN CONNECTION THEREWITH OR THE TRANSACTIONS RELATED THERETO. EACH OF
THE BORROWERS AND LENDER HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND,
ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND
THAT ANY OF THEM MAY FILE AS AN ORIGINAL COUNTERPART OR A COPY OF THIS AGREEMENT
WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE
WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

SECTION 10.16. CONFIDENTIALITY. Neither Borrower shall at any time
before or after payment in full and satisfaction of all of the Obligations,
reveal, divulge or make known, or knowingly permit to be so revealed, divulged
or made known, to any Person (including persons within its own organization who
do not have a definite need to know for the purpose of performance of this
Agreement), the terms or conditions of this Agreement or any document or
agreement now or hereafter executed in connection herewith; PROVIDED that the
foregoing shall not apply to information required to be disclosed by order of a
court of competent jurisdiction or in connection with any governmental
investigation (in each case to the extent disclosure is required, but no
further) so long as such Borrower notifies the Lender in writing of any
circumstances of which such Borrower is aware that may lead to such a
requirement or order, so as to allow Lender to take steps to contest such order
or investigation; PROVIDED, FURTHER, that the foregoing shall not apply to
information which is required to be disclosed by such Borrower or information
which in the reasonable determination of such Borrower is desirable for such
Borrower to disclose, pursuant to federal or state securities laws, pursuant to
the rules or regulations of the FCC, any PUC or other applicable Governmental
Authority or to disclosure of information to Persons who may potentially provide
debt financing (other than a lender providing secured financing to such Borrower
or any debt financing in replacement of the Loans) or equity financing to such
Borrower or any Affiliate with respect to its Business and any consultants or

advisors of such Person, or to Persons who are consultants, advisors (including
but not limited to attorneys and auditors), officers, directors or employees of
such Borrower, provided that each such Person is required by such Borrower to
keep such information confidential.

SECTION 10.17. ADDITIONAL FINANCING BY BORROWERS. Lender
acknowledges that Borrowers are contemplating additional financing which may
include equity or unsecured debt facilities. Notwithstanding the provisions of
SECTION 6.04 and 6.13 but subject to (i) the prior written consent of Lender not
to be unreasonably withheld, (ii) the execution and delivery by Borrowers and
applicable third parties of subordination, intercreditor and standstill
agreements containing commercially reasonable terms and otherwise acceptable to
Lender, (iii) the absence of any Default or Event of Default as a result of any
such financing other than pursuant to SECTION 6.04 or 6.13, the Borrowers shall
be permitted to obtain such additional financing.

SECTION 10.18. ENTIRE AGREEMENT, ETC. This Agreement (including all
schedules and exhibits referred to herein), the Notes and all other Loan
Documents constitute the entire contract between the parties hereto with respect
to the subject matter hereof and thereof and shall supersede and take the place
of any other instrument purporting to be an agreement of the parties hereto
relating to such subject matter.

SECTION 10.19. NO STRICT CONSTRUCTION. The parties hereto have
participated, jointly in the negotiation and drafting of this Agreement. In the
