      Administrative Agent shall promptly notify Lenders of each such notice.
Each Lender shall, before 2:00 p.m. on the date of each Advance under the
Domestic Revolver Loan or the Foreign Revolver Loan hereunder, make available to
Administrative Agent, at its office at Bank of America Plaza, 901 Main Street,

wiring such amounts pursuant to any wiring instructions, or (ii) depositing such
amount in the account of the applicable Borrower at the Administrative Agent, in
each case as specified by the applicable Borrower to the Administrative Agent in

      (d) Unless a Lender shall have notified Administrative Agent prior to the

Percentage of any Advance, Administrative Agent may assume that such Lender has
made the appropriate amount available in accordance with Section 2.02(a) hereof,
and Administrative Agent may, in reliance upon such assumption, make available
to the applicable Borrower a corresponding amount. If and to the extent any
Lender shall not have made such amount available to Administrative Agent, such
Lender and the applicable Borrower severally agree to repay to Administrative
Agent immediately on demand such corresponding amount together with interest
thereon, from the date such amount is made available to such Borrower until the
date such amount is repaid to Administrative Agent, at (i) in the case of such
Borrower, the Base Rate, and (ii) in the case of such Lender, the Federal Funds

Percentage of any Advance hereunder shall not relieve any other Lender of its
obligation, if any, to make available its Applicable Specified Percentage of any
Advance. In no event, however, shall any Lender be responsible for the failure
of any other Lender to make available any portion of any Advance.

as a result of the Borrower's failure to prepay. A certificate of each Lender
claiming compensation under this Section 2.04(a), setting forth in reasonable

hereunder shall be presumptive evidence of the validity of such claim.

      (b) The application of prepayments made under this Section 2.04 as between

equal to 100% of the Net Proceeds from any such offering. Net Proceeds received
by the Foreign Borrower or the FB Subsidiaries will first be applied to the
Foreign Revolver Loan. Net Proceeds received by the Domestic Borrower and DB
Subsidiaries will be applied first to the Domestic Revolver Loan.

      (c) Mandatory Prepayments, Generally. Except as otherwise specifically

         Agreement, (B) shall not bear any Interest under this Agreement, and
         (C) shall not be payable by the Borrowers to the extent that the
         Borrowers pay all Obligations in full (other than the Interest Accrual
         and the Fee Accrual)on or before the Maturity Date. The Interest
         Accrual becomes due and payable on the first day following the Maturity
         Date if the Obligations (other than the Interest Accrual and the Fee
         Accrual) have not been paid in full or upon the Administrative Agent
         electing any of the remedies provided for in Section 9.02(a) through
         (d), and interest shall thereafter accrue at the Default Rate on all
         the outstanding Advances. If the amount of interest payable in respect
         of any interest computation period is reduced to the Highest Lawful
         Rate and the amount of interest payable in respect of any subsequent
         interest computation period would be less than the Maximum Amount, then
         the amount of interest payable in respect of such subsequent interest
         computation period shall be automatically increased to the Maximum
         Amount; provided that at no time shall the aggregate amount by which
         interest paid has been increased pursuant to this sentence exceed the

         Base Advances shall be paid at the Base Rate monthly in arrears on the
         first Business Day of each subsequent calendar month and on the
         Maturity Date.

outstanding and on all other Obligations due and unpaid hereunder at a per annum
rate equal to the lesser of the (a) the Highest Lawful Rate and (b) the Base
Rate plus 3.00% (the "Default Rate").

      (a) Mandatory Termination of the Commitment. The Commitment shall

shall be reduced immediately and automatically pro rata (unless otherwise
allocated by the Borrowers in accordance with the ownership of the assets sold)
in an amount equal to (i) (A) 100% of any amount in excess of $15,000,000 but
less than or equal to $42,000,000 of the Net Proceeds from the first phase of
the MFN Sale and (B) 50% of any amount in excess of $42,000,000 of the Net
Proceeds from the first phase of the MFN Sale, and (ii) 50% of any other amount
that would be required by Section 2.05(a) hereof to prepay the Loan, regardless
of the outstanding amount of Advances thereunder, as a result of any Asset Sales
of either Borrower or any Subsidiary of either Borrower (this provision in and
of itself not constituting permission to effectuate any Asset Sales).

      (c) Mandatory Reduction of Commitment Due to Issuances of Public or
Private Equity or Debt. At the time of any issuance of public or private equity
securities or Debt by either Borrower or any of their Subsidiaries (other than
Debt permitted to be incurred in accordance with the provisions of Section 8.02)
(this provision in and of itself not constituting permission to effectuate any
such transaction), the Commitment shall be reduced immediately and automatically
in an amount equal to 50% of any amount required by Section 2.05(b) hereof to
prepay outstanding Advances under the Loan (regardless of whether there are
actually any outstanding Advances) as a result of any issuances of public or
private equity securities or Debt. Net Proceeds received by the Foreign Borrower
or the FB Subsidiaries as a result of the issuance of public or private equity
or Debt by such entities will first be applied to reduce the Foreign Revolver
Commitment. Net Proceeds received by the Domestic Borrower and DB Subsidiaries
as a result of the issuance of public or private equity or Debt by such entities
will be applied first to reduce the Domestic Revolver Commitment.

      (d) Change of Control. If any Change of Control shall have occurred, the
Commitment shall immediately and automatically be reduced to zero.

      (e) Voluntary Commitment Reductions. Either Borrower may from time to

the accrued interest at the Base Rate and the applicable accrued Commitment Fee
on the amount of such reduction and all amounts due, and any partial reduction
shall be in an aggregate amount which is an integral multiple of $100,000.

      (f) Commitment Reduction and Repayments, Generally. Both voluntary and
mandatory reductions of the Commitment shall be apportioned between the Domestic
Revolver Commitment and the Foreign Revolver Commitment in accordance with the
terms of Section 2.13(f) hereof. To the extent outstanding Domestic Revolver
Advances exceed the Domestic Revolver Commitment after any reduction thereof,
the Domestic Borrower shall repay, on the









                                       29
<PAGE>   30

date of such reduction, any such excess amount and all accrued interest at the
Base Rate thereon, the applicable Domestic Revolver Commitment Fee on the amount
of such reduction and all other amounts due. To the extent the (i) Foreign
Revolver Advances plus (ii) the undrawn face amount of all outstanding Letters
of Credit, plus (iii) reimbursement obligations under Article III hereof (or if
any Letters of Credit or reimbursement obligations are denominated in a currency
other than Dollars, the Dollar equivalent of such currency) exceed the Foreign
Revolver Commitment after any reduction thereof, the Foreign Borrower shall
repay, on the date of such reduction, any such excess amount and all accrued
interest at the Base Rate thereon, the applicable Foreign Revolver Commitment
Fee on the amount of such reduction and all other amounts due. Once reduced or
terminated, the Domestic Revolver Commitment and the Foreign Revolver Commitment
may not be increased or reinstated.

      2.12. Funding Losses. Either Borrower may prepay the outstanding principal
balance of any Advance, in full at any time or in part from time to time in
accordance with the terms of Section 2.04 hereof, provided, that as a condition
precedent to the Borrower's right to make, and any Lender's obligation to
accept, any such prepayment, each such prepayment shall be in the amount of 100%
of the principal amount to be prepaid, plus accrued unpaid interest thereon to
the date of prepayment, plus any other sums which have become due to
Administrative Agent and Lenders under the Loan Papers on or before the
prepayment date but have not been paid.

      The Borrowers agree that each Lender is not obligated to actually reinvest
the amount prepaid in any specific obligation as a condition to receiving any
Consequential Loss, or otherwise.

      2.13. Computations and Manner of Payments.

      (a) The Borrowers shall make each payment hereunder and under the other
Loan Papers not later than 1:00 p.m. on the day when due in same day funds (by
wire transfer or otherwise) to Administrative Agent, for the account of Lenders
unless otherwise specifically provided herein, at Administrative Agent's office
at Bank of America Plaza, 901 Main Street, Dallas, Texas 75202, referencing
Pacific Gateway Exchange, Inc. or Pacific Gateway Exchange (Bermuda) Limited, as
applicable. No later than the end of each day when each payment hereunder is
made, the Borrower shall notify Loan Operations at (214) 209-0989 or such other
Person as Administrative Agent may from time to time specify.

      (b) Unless Administrative Agent shall have received notice from a Borrower
prior to the date on which any payment is due hereunder that such Borrower will
not make payment in full, Administrative Agent may assume that such payment is
so made on such date and may, in reliance upon such assumption, make
distributions to Lenders. If and to the extent a Borrower shall not have made
such payment in full, each Lender shall repay to Administrative Agent forthwith
on demand the applicable amount distributed, together with interest thereon at
the Federal Funds Rate, from the date of distribution until the date of
repayment. Each Borrower hereby authorizes each Lender, if and to the extent
payment is not made when due hereunder, to charge the amount so due against any
account of either Borrower with such Lender.

      (c) Subject to Section 11.08 hereof, interest on Base Advances, the
Commitment Fee








                                       30
<PAGE>   31

and other amounts due under the Loan Papers shall be calculated on the basis of
actual days elapsed but computed as if each year consisted of 365 or 366 days,
as applicable. Such computations shall be made including the first day but
excluding the last day occurring in the period for which such interest, payment
or Commitment Fee is payable. Each determination by Administrative Agent or a
Lender of an interest rate, fee or commission hereunder shall be presumptive
evidence of the validity of such claim. All payments under the Loan Papers shall
be made in United States dollars, and without setoff, counterclaim, or other
defense.

      (d) Whenever any payment to be made hereunder or under any other Loan
Papers shall be stated to be due on a day other than a Business Day, such
payment shall be made on the next succeeding Business Day, and such extension of
time shall be included in the computation of interest or fees, if applicable.

      (e) Reference to any particular index or reference rate for determining
any applicable interest rate under this Agreement is for purposes of calculating
the interest due and is not intended as and shall not be construed as requiring
any Lender to actually obtain funds for any Advance at any particular index or
reference rate.

      (f) Except as provided pursuant to Section 2.11(b), (c), (d) and (f)
hereof, to the extent either Borrower makes any voluntary prepayment, or
voluntary reduction of the Commitment under Section 2.04 or 2.11 hereof, or any
mandatory prepayment, or mandatory reduction of the Commitment under Section
2.05 or 2.11 hereof, then such reduction of Commitment or such prepayment shall
be applied, first to the Domestic Revolver Commitment unless such application
would yield adverse tax consequences (provided that regardless of such tax
consequences, Net Proceeds from Asset Sales or the issuance of Debt for Borrowed
Money by the Domestic Borrower or any Domestic DB Subsidiary shall be applied to
the Domestic Revolver Commitment until the Domestic Revolver Commitment has been
terminated and all Obligations under the Domestic Revolver Commitment are paid
in full), and second, to the Foreign Revolver Commitment.

      2.14. Intentionally Deleted.

      2.15. Use of Proceeds. The Advances shall be available (and the Borrowers
shall use such proceeds) in the ordinary course of its existing business.

annum fee for each Letter of Credit equal to the higher of (i) $350.00 and (ii)

face amount of each such Letter of Credit (or if such Letter of Credit is
denominated in a currency other than Dollars, the Dollar equivalent of such
currency calculated by using the quoted spot rate to exchange Dollars for such
currency in effect on the last day of each month as the rate in effect during
the calendar month ending on such date). Each fee for each Letter of Credit
under this subsection shall be due and payable to the Administrative Agent
monthly as it accrues, on each the first Business Day of each subsequent
calendar month during the term of the Letter of Credit and on the expiration or
renewal and/or extension of each such Letter of Credit, beginning with the first

expiration date of each such Letter of Credit. Additionally, a fee of 2.00% per
annum (the "Fee Accrual") shall accrue as a separate obligation on the undrawn
portion of each issued and outstanding Letter of Credit. The Fee Accrual shall
not bear any Interest under this Agreement and shall not be payable by the
Borrowers to the extent that the Borrowers pay all Obligations in full (other

remedies provided for in Section 9.02(a) through (d) of this Agreement, and
interest shall thereafter accrue at the Default Rate on the undrawn portion of
all issued and outstanding Letters of Credit.

                                       33
<PAGE>   34

      (a) The Foreign Borrower hereby agrees to reimburse Administrative Agent
immediately upon demand by Administrative Agent, and in immediately available
funds, for any payment or disbursement made by Administrative Agent under any
Letter of Credit. Administrative Agent shall notify Foreign Borrower within one
Business Day of its receipt of a draw request with respect to a Letter of Credit
issued in a currency other than Dollars. Foreign Borrower, within one Business
Day of receipt of such notice from Administrative Agent, shall notify
Administrative Agent whether Foreign Borrower intends to make funds available to
Administrative Agent in such currency. Payment shall be made by the Foreign
Borrower with interest on the amount so paid or disbursed by Administrative
Agent from and including the date payment is made under any Letter of Credit to
and including the date of payment (which shall be no later than 5 days after the
date of demand by the Administrative Agent), at the lesser of (i) the Highest
Lawful Rate, and (ii) the sum of the Base Rate in effect from time to time plus
2.00% per annum; provided, however, that if the Foreign Borrower would be
permitted under the terms of Section 2.01, Section 2.02 and Section 4.02 to
borrow Foreign Revolver Advances in amounts at least equal to their
reimbursement obligation for a drawing under any Letter of Credit, a Base
Advance by each Lender, in an amount equal to such Lender's Foreign Revolver
Specified Percentage, shall automatically be deemed made on the date of any such
payment or disbursement made by Administrative Agent in the amount of such
obligation and subject to the terms of this Agreement. To the extent that the
Foreign Borrower fails to reimburse the Administrative Agent for funds disbursed
as a result of a funding under a Letter of Credit when a Base Advance is not
available within 5 days of the demand for such payment by the Administrative
Agent, interest on such disbursement shall accrue at the lesser of (i) the
Highest Lawful Rate, and (ii) the sum of the Base Rate in effect from time to
time plus 4.00% per annum.

      (b) The Foreign Borrower hereby also agrees to pay to Administrative Agent
immediately upon demand by Administrative Agent and in immediately available
funds, as security for their reimbursement obligations in respect of the Letters
of Credit under Section 3.03(a) hereof and any other amounts payable hereunder
and under the Notes, an amount equal to the aggregate Dollar amount available to
be drawn under Letters of Credit then outstanding (or if any Letter of Credit is
denominated in a currency other than Dollars, the Dollar equivalent of such
currency), irrespective of whether the Letters of Credit have been drawn upon,
upon an Event of Default. Any such payments shall be deposited in a separate
account designated "Pacific Gateway Exchange (Bermuda) Limited Special Account"
or such other designation as Administrative Agent shall elect. All such amounts
deposited with Administrative Agent shall be and shall remain funds of the
Foreign Borrower on deposit with Administrative Agent and may be invested by
Administrative Agent as Administrative Agent shall determine. Such amounts may
not be used by Administrative Agent to pay the drawings under the Letters of
Credit; however, such amounts may be used by Administrative Agent as
reimbursement for Letter of Credit drawings which Administrative Agent has paid.
During the existence of an Event of Default but after the expiration of any
Letter of Credit that was not drawn upon, the Foreign Borrower may direct the
Administrative Agent to use any cash collateral for any such expired Letter of
Credit, if any, to reduce the amount of the Obligations. Any amounts remaining
in the Pacific Gateway Exchange (Bermuda) Limited Special Account, after the
date of the expiration of all Letters of Credit and after all Obligations have
been paid in full, or after the Event of Default shall cease to exist shall be
repaid to the Foreign Borrower promptly thereafter.

<PAGE>   35

         (c) The obligations of the Foreign Borrower under this Section 3.03
will continue until all Letters of Credit have expired and all reimbursement
obligations with respect thereto have been paid in full by the Foreign Borrower
and until all other Obligations shall have been paid in full.

         (d) The Foreign Borrower shall be obligated to reimburse Administrative
Agent upon demand for all amounts paid under the Letters of Credit as set forth
in Section 3.03(a) hereof; provided, however, if the Foreign Borrower for any
reason fails to reimburse Administrative Agent in full upon demand, whether by
borrowing Foreign Revolver Advances to pay such reimbursement obligations or
otherwise, the Lenders shall reimburse Administrative Agent in accordance with
each Lender's Foreign Revolver Specified Percentage for amounts due and unpaid
from the Foreign Borrower as set forth in Section 3.04 hereof; provided,
however, that no such reimbursement made by the Lenders shall discharge the
Foreign Borrower's obligations to reimburse Administrative Agent.

         (e) The Foreign Borrower shall indemnify and hold Administrative Agent
or any Lender, its officers, directors, representatives and employees harmless
from loss for any claim, demand or liability which may be asserted against
Administrative Agent or such indemnified party in connection with actions taken
under the Letters of Credit or in connection therewith (INCLUDING LOSSES
RESULTING FROM THE NEGLIGENCE (BUT NOT THE GROSS NEGLIGENCE) OF ADMINISTRATIVE
AGENT OR SUCH INDEMNIFIED PARTY), and shall pay Administrative Agent for
reasonable fees of attorneys (who may be employees of Administrative Agent) and
legal costs paid or incurred by Administrative Agent in connection with any
matter related to the Letters of Credit, except for losses and liabilities
incurred as a direct result of the gross negligence or wilful misconduct of
Administrative Agent or such indemnified party. If the Foreign Borrower for any
reason fails to indemnify or pay Administrative Agent or such indemnified party
as set forth herein in full, the Lenders shall indemnify and pay Administrative
Agent upon demand, in accordance with each Lender's Foreign Revolver Specified
Percentage of such amounts due and unpaid from the Foreign Borrower. The
provisions of this Section 3.03(e) shall survive the termination of this
Agreement.

      3.04. Lenders' Obligations. Each Lender agrees, unconditionally and
irrevocably to reimburse Administrative Agent on demand for such Lender's
Foreign Revolver Specified Percentage of each draw paid by Administrative Agent
under any Letter of Credit (or if such Letter of Credit is denominated in a
currency other than Dollars, the Dollar equivalent of such currency). All
amounts payable by any Lender under this subsection shall include interest
thereon at the Federal Funds Rate, from the date of the applicable draw to the
date of reimbursement by such Lender. No Lender shall be liable for the
performance or nonperformance of the obligations of any other Lender under this
Section. The obligations of the Lenders under this Section shall continue after
the Maturity Date and shall survive termination of any Loan Papers.

      3.05. Administrative Agent's Obligations.

payment of any Letter of Credit due to Administrative Agent's gross negligence
or willful misconduct. Administrative Agent shall incur no liability to any
Lender, the Foreign Borrower or any Affiliate of the Foreign Borrower or Lender
in acting upon any notice, document, order, consent, certificate, warrant or

Date and listed on Schedule 5.01(a) hereto are true and correct. Each of the
Borrowers and the Subsidiaries (other than PGE Switzerland) is a entity duly
organized, validly existing and in good standing under the laws of its state or
country of organization. Each of the Borrowers and the Subsidiaries has the
corporate power and corporate authority to own its properties and to carry on
its business as now being conducted. Each of the Borrowers and the Subsidiaries
(other than PGE Switzerland) is duly qualified, in good standing and authorized
to do business in each jurisdiction in which the character of its Properties or
the nature of its business requires such qualification or authorization, except
where the failure to so qualify could not reasonably be expected to cause a
Material Adverse Change.

         (b) The Borrowers have the corporate power and has taken all necessary
corporate action to authorize it to borrow hereunder. Each of the Borrowers and
the Subsidiaries has corporate power and has taken all necessary corporate
action to execute, deliver and perform the







                                       39

Loan Papers to which it is party in accordance with the terms thereof, and to
consummate the transactions contemplated thereby. Each Loan Paper has been duly
executed and delivered by the Borrowers or such Subsidiary executing it. Each of
the Loan Papers to which the Borrowers and the Approved Subsidiaries are party
is a legal, valid and binding obligation of each of the Borrowers or such
Approved Subsidiary, as applicable, enforceable in accordance with its terms,
subject, to enforcement of remedies, to the following qualifications: (i)
equitable principles generally, and (ii) bankruptcy, insolvency, liquidation,
reorganization, reconstruction and other similar laws affecting enforcement of
creditors' rights generally (insofar as any such law relates to the bankruptcy,
insolvency or similar event of either of the Borrowers or any Approved
Subsidiary of the Borrowers).

      (c) The execution, delivery and performance by the Borrowers and the
Subsidiaries of the other Loan Papers to which they are respectively a party,
and the consummation of the transactions contemplated thereby, do not and will
not (i) require any consent or approval not already obtained, (ii) violate any
Applicable Law, (iii) conflict with, result in a breach of, or constitute a
default under the articles of incorporation or by-laws (or memorandum of
association or bye-laws) of either of the Borrowers or any Subsidiary, or under
any material License, indenture, agreement or other instrument, to which either
of the Borrowers or any Subsidiary is a party or beneficiary of, or by which
they or their respective Properties may be bound, or (iv) result in or require
the creation or imposition of any Lien upon or with respect to any property now
owned or hereafter acquired by either of the Borrowers or any Subsidiary, except
Permitted Liens, except, with respect to any of the foregoing, which could not
reasonably be expected to cause a Material Adverse Change.

      (d) The Borrowers and its Subsidiaries are primarily engaged in the
operation of telecommunications and internet businesses and pursuing activities
related thereto.

      (e) On the Closing Date, all material Licenses of the Borrowers and the
Subsidiaries have been duly authorized and obtained, and are in full force and
effect. The Borrowers and the Subsidiaries are in compliance in all material
respects with all provisions thereof. On the Closing Date, no material License
is the subject of any pending or, to the best of the Borrowers' knowledge,
threatened challenge or revocation. On each date after the Closing Date on which
this representation is deemed to be made, no material License is the subject of
any pending or, to the best of the Borrowers' knowledge, threatened challenge or
revocation, which such event could reasonably be expected to cause a Material
Adverse Change. The Borrowers and the Subsidiaries are not required to obtain
any material License that has not already been obtained from, or effect any
material filing or registration that has not already been effected with, the
FCC, any applicable PUC or any other federal, state or local regulatory
authority in connection with the execution and delivery of this Agreement or any
other Loan Paper, or the performance thereof (other than any enforcement of
remedies by the Administrative Agent on behalf of the Lenders), in accordance
with their respective terms, including any borrowings hereunder.

         (f) The Borrowers and the Subsidiaries are in compliance in all
material respects with all material Applicable Laws. The Borrowers and the
Subsidiaries have duly and timely filed all reports, statements and filings that
are required to be filed by any of them under the








                                       40
<PAGE>   41

Communications Act, and are in all material respects in compliance therewith,
including without limitation the rules and regulations of the FCC and each
applicable PUC. Except as set forth on Schedule 5.01(f) hereto, as of the
Closing Date, the Borrowers are not aware of any event or circumstance
constituting noncompliance (or any Person alleging noncompliance) with any rule
or regulation of the FCC or any applicable PUC. On each date after the Closing
Date on which this representation is deemed to be made, the Borrowers are not
aware of any event or circumstance constituting noncompliance (or any Person
alleging noncompliance) with any rule or regulation of the FCC or any applicable
PUC, which such event or circumstance could reasonably be expected to cause a
Material Adverse Change.

      (g) On the Closing Date, the Borrowers and the Subsidiaries have good and
indefeasible title to, or a valid leasehold interest in, all of their material
assets and Properties. On each date after the Closing Date on which this
representation is deemed to be made, the Borrowers and the Subsidiaries have
good and indefeasible title to, or a valid leasehold interest in, all of their
material assets and Properties, in which any such failure could reasonably be
expected to cause a Material Adverse Change. None of the assets of the Borrowers
or the Subsidiaries is subject to any Liens, except Permitted Liens and Liens
permitted under Section 8.03(b) hereof. No financing statement or other Lien
filing authorized by either of the Borrowers or any Subsidiary (except relating
to Permitted Liens and Liens permitted by Section 8.03(b) hereof) is on file in
any state or jurisdiction that names either Borrower or any of the Subsidiaries
as debtor or covers (or purports to cover) any assets of either Borrower or any
of the Subsidiaries. Neither the Borrowers nor any of the Subsidiaries have
signed any such financing statement or filing, nor any security agreement
authorizing any Person to file any such financing statement or filing.

      (h) On the Closing Date, except as reflected on Schedule 5.01(h) hereto or
publically reported shareholder class action suits, there is no material action,
suit, proceeding or any other Litigation pending against, the Borrowers or any
of their Subsidiaries, or in any other manner relating directly and materially
adversely to the Borrowers any of their Subsidiaries, or any of their material
Properties, in any court or before any arbitrator of any kind or before or by
any governmental body. On each date after the Closing Date on which this
representation is deemed to be made, there is no action, suit, proceeding or any
other Litigation pending against, the Borrowers or any of their Subsidiaries, or
in any other manner relating to the Borrowers or any of their Subsidiaries, or
any of their Properties, in any court or before any arbitrator of any kind or
before or by any governmental body, which could reasonably be expected to cause
a Material Adverse Change other than litigation of the nature and type of
shareholder class action suits described on Schedule 5.01(h) or that are
publically reported.

      (i) All material federal, state and other Tax returns of the Borrowers and
their Subsidiaries required by law to be filed have been duly filed and all
Taxes, assessments and governmental charges or levies imposed upon either of the
Borrowers or their Subsidiaries or any of their Properties, income, profits and
assets, except those that are diligently contested in good faith by the
Borrowers and for which adequate reserves have been established in accordance
with GAAP, and no Lien (other than a Permitted Lien) has attached and no
foreclosure, distraint, sale or similar proceedings have been commenced.









                                       41

      (j) The Borrowers have furnished or caused to be furnished to the Lenders
copies of its financial statements at December 31, 1999 which are prepared in
good faith and complete in all material respects. Each such statement presents
fairly in all material respects and in accordance with GAAP the financial
position of the Borrowers and the Subsidiaries as at such dates, and the results
of operations for the periods then ended. The Borrowers and the Subsidiaries
have no material liabilities, contingent or otherwise, nor material losses,
except as disclosed in writing to the Lenders prior to the Closing Date or as
disclosed on any subsequent financial statements. On the Closing Date after
giving effect to the Advances made on such date, the Borrowers and their
Subsidiaries on a consolidated basis are Solvent.

      (k) None of the Borrowers or their Controlled Group maintains or
contributes to any Plan other than those disclosed to the Administrative Agent
in writing. Each such Plan is in compliance in all material respects with the
applicable provisions of ERISA, the Code, and any other applicable Federal or
state law, rule or regulation. With respect to each Plan of either Borrower and
each member of its Controlled Group (other than a Multiemployer Plan), all
reports required under ERISA or any other Applicable Law to be filed with any
governmental authority, the failure of which to file could reasonably result in
liability of such Borrower or any member of its Controlled Group in excess of
$100,000, have been duly filed. All such reports are true and correct in all
material respects as of the date given. No such Plan of either Borrower or any
member of its Controlled Group has any accumulated funding deficiency (as
defined in Section 412(a) of the Code) (without regard to any waiver granted
under Section 412 of the Code), nor has any funding waiver from the Internal
Revenue Service been received or requested. None of the Borrowers or any member
of its Controlled Group has failed to make any contribution or pay any amount
due or owing as required by Section 412 of the Code or Section 302 of ERISA or
the terms of any such Plan prior to the due date under Section 412 of the Code
and Section 302 of ERISA. There has been no ERISA Event or any event requiring
disclosure under Section 4041(c)(3)(C), 4068(f), 4063(a) or 4043(b) of ERISA
with respect to any Plan or trust of the Borrowers or any member of its
Controlled Group since the effective date of ERISA. The value of the assets of
each Plan (other than a Multiemployer Plan) of the Borrowers and each member of
its Controlled Group equaled or exceeded the present value of the benefit
liabilities, as defined in Title IV of ERISA, of each such Plan as of the most
recent valuation date using Plan actuarial assumptions at such date. There are
no pending or, to the best of the Borrowers' knowledge, threatened claims,
lawsuits or actions (other than routine claims for benefits in the ordinary
course) asserted or instituted against, and neither the Borrowers nor any member
of their Controlled Group has knowledge of any threatened Litigation or claims
against, (i) the assets of any Plan or trust or against any fiduciary of a Plan
with respect to the operation of such Plan, or (ii) the assets of any employee
welfare benefit plan within the meaning of Section 3(1) or ERISA, or against any
fiduciary thereof with respect to the operation of any such plan. None of the
Borrowers or any member of their Controlled Group has engaged in any non-exempt
prohibited transactions, within the meaning of Section 406 or Section 4.08 of
ERISA or Section 4975 of the Code, in connection with any Plan. None of the
Borrowers or any member of their Controlled Group has incurred or reasonably
expects to incur (A) any liability under Title IV of ERISA (other than premiums
due under Section 4007 of ERISA to the PBGC), (B) any withdrawal liability (and
no event has occurred which with the giving of notice under Section 4219 of
ERISA would result in such liability) under Section 4201 of ERISA as a result of
a complete or partial








                                       42
<PAGE>   43

withdrawal (within the meaning of Section 4203 or 4205 of ERISA) from a
Multiemployer Plan, or (C) any liability under Section 4062 of ERISA to the PBGC
or to a trustee appointed under Section 4042 of ERISA. None of the Borrowers,
any member of their Controlled Group, or any organization to which either
Borrower or any member of their Controlled Group is a successor or parent
corporation within the meaning of ERISA Section 4069(b), has engaged in a
transaction within the meaning of ERISA Section 4069. None of the Borrowers or
any member of their Controlled Group maintains or has established any welfare
benefit plan within the meaning of Section 3(1) of ERISA which provides for
continuing benefits or coverage for any participant or any beneficiary of any
participant after such participant's termination of employment except as may be
required by the Consolidated Omnibus Budget Reconciliation Act of 1985, as
amended ("COBRA") and the regulations thereunder, and at the expense of the
participant or the beneficiary of the participant, or retiree medical
liabilities. Each of the Borrowers and their Controlled Group which maintains a
welfare benefit plan within the meaning of Section 3(1) of ERISA has complied in
all material respects with any applicable notice and continuation requirements
of COBRA and the regulations thereunder.

      (l) The Borrowers are not, nor are any of the Subsidiaries engaged
principally or as one of its important activities in the business of extending
credit for the purpose of purchasing or carrying any margin stock within the
meaning of Regulations T, U and X of the Board of Governors of the Federal
Reserve System, and no part of the proceeds of the Advances will be used to
purchase or carry any margin stock (as defined by Regulation U) or to extend
credit to others for the purpose of purchasing or carrying any margin stock. Not
more than 25% of the assets of either Borrower or any of their Subsidiaries are
margin stock (as defined by Regulation U), and none of the Capital Stock of
either Borrower's Subsidiaries is margin stock. None of the Borrowers or their
Subsidiaries, nor any agent acting on their behalf, have taken or will knowingly
take any action which might cause this Agreement or any Loan Papers to violate
any regulation of the Board of Governors of the Federal Reserve System or to
violate the Exchange Act, in each case as in effect now or as the same may
hereafter be in effect.

      (m) The Borrowers and the Subsidiaries (other than PGE Switzerland) are in
compliance with all of the material provisions of their articles of
incorporation and by-laws.

      (n) Neither Borrower is, nor are any of their Subsidiaries, required to
register under the provisions of the Investment Company Act of 1940, as amended.
Neither the entering into or performance by the Borrowers of this Agreement nor
the issuance of the Notes, nor the execution, delivery and performance of the
obligations under the Loan Papers by the Borrowers and their Subsidiaries,
violates any provision of such act or requires any consent, approval, or
authorization of, or registration with, the Securities and Exchange Commission
or any other governmental or public body of authority pursuant to any provisions
of such act.

      (o) On the Closing Date, neither of the Borrowers or any of their
Subsidiaries has any actual knowledge or reason to believe that any substance
deemed hazardous by any applicable Environmental Law, has been installed on any
real property now owned by the Borrower or any of its Subsidiaries, except (i)
for hazardous substances the presence of which is not in violation of law and
(ii) as disclosed in writing to the Lenders. On each date after the Closing Date
on which







                                       43

<PAGE>   44

this representation is deemed to be made, neither of the Borrowers nor any
Subsidiary has any actual knowledge or reason to believe that any substance
deemed hazardous by any applicable Environmental Law, has been installed in
violation of law on any real property now owned by either Borrower or any of
their Subsidiaries except as disclosed to the Lenders in writing, and which
could, in the reasonable judgment of the Borrowers, be expected to cause a
Material Adverse Change. As of the Closing Date, neither the Borrowers nor the
Subsidiaries are in violation of or subject to any existing, pending or, to the
best of either Borrower's knowledge, threatened investigation or inquiry by any
governmental authority or to any material remedial obligations under any
applicable Environmental Laws, and this representation and warranty would
continue to be true and correct following disclosure to the applicable
governmental authorities of all relevant facts, conditions and circumstances, if
any, pertaining to any real property of either Borrower or the Subsidiaries. On
each date after the Closing Date on which this representation is deemed to be
made, neither the Borrowers nor the Subsidiaries are in violation of or subject
to any existing, pending or, to the best of either Borrower's knowledge,
threatened investigation or inquiry by any governmental authority or to any
material remedial obligations under any applicable Environmental Laws which
could reasonably be expected to cause a Material Adverse Change, and this
representation and warranty would continue to be true and correct following
disclosure to the applicable governmental authorities of all relevant facts,
conditions and circumstances, if any, pertaining to any real property of either
Borrower or the Subsidiaries. Neither the Borrowers nor the Subsidiaries are
required to obtain any permits, Licenses or similar authorizations to construct,
occupy, operate or use any buildings, improvements, fixtures, and equipment
forming a part of any real property of either Borrower or any Subsidiary by
reason of any applicable Environmental Laws, except those that have been
obtained. As of the Closing Date, neither Borrower nor any or their Subsidiaries
have actual knowledge or reason to believe, after reasonable investigation, that
any hazardous substances or solid wastes have been disposed of or otherwise
released on or to the real property of either Borrower or any of their
Subsidiaries in violation of any applicable Environmental Law, except as could
be not reasonably be expected to cause a Material Adverse Change. On each date
after the Closing Date on which this representation is deemed to be made,
neither Borrower nor any of their Subsidiaries have actual knowledge or reason
to believe, that any hazardous substances or solid wastes have been disposed of
or otherwise released on or to the real property of either Borrower any of their
Subsidiaries, within the meaning of the applicable Environmental Laws, except as
disclosed to the Lenders and which such disposal or release could not reasonably
be expected to cause a Material Adverse Change.

      (p) On the Closing Date, there is no pending Litigation that has not been
disclosed in writing to the Lenders either directly or through SEC filings.

      (q) All Capital Stock of the Borrowers and their Subsidiaries has been
duly authorized and validly issued, and is fully paid and nonassessable. The
Capital Stock described on Schedule 5.01(a) hereto constitutes all the issued
and outstanding Capital Stock of the Foreign Borrower and all the direct and
indirect Subsidiaries of either Borrower, except such shares that have been
issued after the Closing Date. No Person has conversion rights with respect to,
or any subscription rights, calls, commitments or claims of any character for,
or any repurchase or redemption options relating to, the Capital Stock of either
Borrower and their Subsidiaries, other










                                       44
<PAGE>   45

than those rights that have been waived, except as disclosed on Schedule
5.01(q). The Capital Stock of the Borrowers and their Subsidiaries when issued
or sold, was either (i) registered or qualified under applicable federal or
state securities laws, or (ii) exempt therefrom.

      (r) No broker's, finder's or other fee or commission will be payable by
either Borrower (other than to the Lenders or their Affiliates hereunder) with
respect to the making of the Commitment or the Advances hereunder. The Borrowers
agree to indemnify and hold harmless the Administrative Agent and each Lender
from and against any claims, demand, liability, proceedings, costs or expenses
asserted with respect to or arising in connection with any such fees or
commissions.

      (s) No event, act or condition has occurred which permits (or with the
passage of time would permit) the revocation or termination of any material
License, which could result in the imposition of any restriction thereon of such
a nature that could reasonably be expected to cause a Material Adverse Change.

      (t) To the best knowledge of the Borrowers, as of the Closing Date, the
Borrowers and their Subsidiaries have obtained all material patents, trademarks,
service-marks, trade names, copyrights, Licenses and other rights, free from
burdensome restrictions, that are necessary for the operation of their business
as presently conducted and as proposed to be conducted, except those, the
failure of which to obtain could not be reasonably expected to cause a Material
Adverse Change. On each date after the Closing Date on which this representation
is deemed to be made, the Borrowers and the Subsidiaries have obtained all
patents, trademarks, service-marks, trade names, copyrights, Licenses and other
rights, free from burdensome restrictions, that are necessary for the operation
of their business as presently conducted and as proposed to be conducted, except
those, the failure of which to obtain could not be reasonably expected to cause
a Material Adverse Change. Nothing has come to the attention of either Borrower
or any of their Subsidiaries to the effect that (i) any process, method, part or
other material presently contemplated to be employed by either Borrower or any
of their Subsidiaries may infringe any patent, trademark, service-mark, trade
name, copyright, License or other right owned by any other Person, or (ii) there
is pending or overtly threatened any claim or Litigation against or affecting
either Borrower or any of their Subsidiaries contesting its right to sell or use
any such process, method, part or other material, which could reasonably be
expected to cause a Material Adverse Change.

      (u) Neither this Agreement nor any other document, certificate or
statement taken as a whole which has been furnished to any Lender by or on
behalf of either Borrower or any of their Subsidiaries in connection with this
Second Amended and Restated Credit Agreement contained any untrue statement of a
material fact or omitted to state a material fact necessary in order to make the
statement contained herein and therein not misleading at the time it was
furnished.

      (v) Neither the Borrowers nor any of their Subsidiaries is a party to any
contractual relationship which is breached or in default solely as a result of
any change in the ownership or management of either Borrower, or the Board of
Directors, unless such Borrower has agreed to a substantially similar provision
in this Agreement.

shall cause their Subsidiaries to (a) engage primarily in the business of
telecommunications and internet, and activities related thereto, and (b) comply

      (a) Each of the Borrowers shall, and shall cause each of their respective
FB or DB Subsidiaries (other than PGE Fiber and PGE Fiber (Bermuda)) to, defend,
protect, indemnify and hold harmless the Administrative Agent, each Lender, each
of their respective Affiliates, and each of their respective (including such
Affiliates') officers, directors, employees, agents, attorneys, shareholders and

nature whatsoever (including, without limitation, the reasonable fees and

whether based on any federal, state, or local laws and regulations), under
common law or at equitable cause, or on contract, tort or otherwise, arising
from or connected with the past, present or future operations of the applicable
Borrower or its respective FB or DB Subsidiaries, or any of their predecessors
in interest, in any manner relating to or arising out of this Agreement, the
Loan Papers, or any act, event or transaction or alleged act, event or
transaction relating or attendant thereto, the making of any participations in
the Advances and the management of the Advances, INCLUDING IN CONNECTION WITH,
OR AS A RESULT, IN WHOLE OR IN PART, OF ANY NEGLIGENCE OF ADMINISTRATIVE AGENT

against the Administrative Agent or any Lender and not either Borrower), or the
use or intended use of the proceeds of the Advances hereunder, or in connection
with any investigation of any potential matter covered hereby, but excluding any
claim or liability to the extent that it arises as the result of the gross
negligence or willful misconduct of any Indemnitee, as finally judicially
determined by a court of competent jurisdiction (collectively, the "Indemnified
Matters").

      (b) In addition, each of the Borrowers shall, and shall cause each of
their respective FB or DB Subsidiaries (other than PGE Fiber and PGE Fiber
(Bermuda)) to, periodically, upon request, reimburse each Indemnitee for its
reasonable legal and other actual expenses (including the cost of any
investigation and preparation) incurred in connection with any Indemnified
Matter. If for any reason the foregoing indemnification is unavailable to any
Indemnitee or insufficient to hold any Indemnitee harmless with respect to
Indemnified Matters, then the applicable Borrowers and their respective FB or DB
Subsidiaries shall contribute to the amount paid or payable by such Indemnitee
as a result of such loss, claim, damage or liability in such proportion as is
appropriate to reflect not only the relative benefits received by such Borrower
or such Subsidiaries, and either Borrower's stockholders or their Subsidiaries'
stockholders, on the one hand and such Indemnitee on the other hand but also the
relative fault of such Borrower or such Subsidiary and such Indemnitee, as well
as any other relevant equitable considerations. The reimbursement, indemnity and
contribution obligations under this Section shall be in addition to any
liability which either Borrower may otherwise have, shall extend upon the same
terms and conditions to each Indemnitee, and shall be binding upon and inure to
the benefit of any successors, assigns, heirs and personal representatives of
the Borrowers and their Subsidiaries, the Administrative Agent, the Lenders and
all other Indemnitees. This Section shall survive any termination of this
Agreement and payment of the Obligations.

      6.10. Environmental Law Compliance. The use which either of the Borrowers
or any of their respective FB or DB Subsidiaries intends to make of any real
Property owned by it will not result in the disposal or other release of any
hazardous substance or solid waste on or to such real Property in violation of
any Environmental Law that could reasonably be expected to cause a Material
Adverse Change. As used herein, the terms "hazardous substance" and "release" as
used in this Section shall have the meanings specified in CERCLA (as defined in
the definition of applicable Environmental Laws), and the terms "solid waste"
and "disposal" shall have the meanings specified in RCRA (as defined in the
definition of applicable Environmental Laws); provided, however, that if CERCLA
or RCRA is amended so as to broaden the meaning of any term defined thereby,
such broader meaning shall apply subsequent to the effective date of such
amendment; and provided further, to the extent that any other law applicable to
either Borrower or any of their respective FB or DB Subsidiaries or any of their
properties and assets establishes a meaning for "hazardous substance,"
"release," "solid waste," or "disposal" which is broader than that specified in
either CERCLA or RCRA, such broader meaning shall apply. Each of the Borrowers
shall, and shall cause their respective FB or DB Subsidiaries (other than PGE
Fiber (Bermuda) and PGE Fiber) to, indemnify and hold the Administrative Agent
and each Lender harmless from and against, and to reimburse them with respect
to, any and all claims, demands, causes of action, loss, damage, liabilities,
costs and expenses (including reasonable attorneys' fees and courts costs) of
any kind or character, known or unknown, fixed or contingent, asserted against
or incurred by any of them at any time and from time to time by reason of or
arising out of (a) the failure of either Borrower or any of their respective FB
or DB Subsidiaries (other than PGE Fiber (Bermuda) and PGE Fiber) to perform any
obligation hereunder regarding asbestos or applicable Environmental Laws, (b)
any violation on or before the Release Date of any applicable Environmental Law
in effect on or before the Release Date, and (c) any act, omission, event or
circumstance existing or occurring on or prior to the Release Date (including
without limitation the presence on such real Property or release from such real
Property of hazardous substances or solid wastes disposed of or otherwise
released on or prior to the Release Date), resulting from or in connection with
the ownership of the real Property, regardless of whether the act, omission,
event or circumstance constituted a violation of any applicable Environmental
Law at the time of its existence or occurrence, or whether the act, omission,
event or circumstance is caused by or relates to the negligence of any
indemnified Person; provided, that such Borrower shall not be under any
obligation to indemnify the Administrative Agent or any Lender to the extent
that any such liability arises as the result of the gross negligence or willful
misconduct of such Person, as finally judicially determined by a court of
competent jurisdiction. The provisions of this paragraph shall survive the
Release Date and shall continue thereafter in full force and effect.

      6.11. Acquisitions, Generally. In connection with any Permitted
Acquisition made by either Borrower or any of their Subsidiaries during the term

prior to such closing together with such other documentation as may be
reasonably be requested by the Lenders.

either Borrower or any such Subsidiary, (ii) in any material respect, articles
of incorporation, by-laws and other organizational documents of either Borrower
or any of their

business for any period of time which, in the aggregate, could reasonably be

      (s) Any of the following shall have occurred:

            (i) Less than 66% of the Capital Stock of the Foreign Borrower shall

            (ii) Less than 100% of the Capital Stock of the Foreign Borrower

      or

      (t) For any reason, the loss of the chief executive officer or the current

      9.02. Remedies upon Default. If an Event of Default described in Section
9.01(h) shall occur, the aggregate unpaid principal balance of and accrued
interest on all Advances shall, to the extent permitted by applicable Law,
thereupon become due and payable concurrently therewith, without any action by
Administrative Agent or any Lender, and without diligence, presentment, demand,
protest, notice of protest or intent to accelerate, or notice of any other kind,
all of which are hereby expressly waived. Subject to the foregoing sentence, if
any Event of Default shall occur and be continuing, Administrative Agent may at
its election, or shall at the direction of the Majority Lenders, do any one or
more of the following:

      (a) Declare the entire unpaid balance of all Obligations immediately due
and payable, whereupon it shall be due and payable without diligence,
presentment, demand, protest, notice of protest or intent to accelerate, or
notice of any other kind (except notices specifically provided for under Section
9.01 hereof), all of which are hereby expressly waived (except to the extent
waiver of the foregoing is not permitted by applicable Law);

      (b) Terminate the Commitments;

      (c) Reduce any claim of Administrative Agent and Lenders to judgment;

      (d) Demand (and the Borrowers shall pay to Administrative Agent)
immediately upon demand and in immediately available funds, the amount equal to
the aggregate amount of the Letters of Credit then outstanding, irrespective of
whether such Letters of Credit have been drawn upon, all as set forth and in
accordance with the terms of provisions of Article III hereof, including the
proviso of Section 3.03(b). The Administrative Agent shall promptly advise the
Borrowers of any such declaration or demand but failure to do so shall not
impair the effect of such declaration or demand; and







                                       61
<PAGE>   62

      (e) Exercise any Rights afforded under any Loan Papers, by Law, including
but not limited to the UCC, at equity, or otherwise.

      9.03. Cumulative Rights. All Rights available to Administrative Agent and
Lenders under the Loan Papers shall be cumulative of and in addition to all
other Rights granted thereto at Law or in equity, whether or not amounts owing
thereunder shall be due and payable, and whether or not Administrative Agent or
any Lender shall have instituted any suit for collection or other action in
connection with the Loan Papers.

      9.04. Waivers. The acceptance by Administrative Agent or any Lender at any
time and from time to time of partial payment of any amount owing under any Loan
Papers shall not be deemed to be a waiver of any Default or Event of Default
then existing. No waiver by Administrative Agent or any Lender of any Default or
Event of Default shall be deemed to be a waiver of any Default or Event of
Default other than such Default or Event of Default. No delay or omission by
Administrative Agent or any Lender in exercising any Right under the Loan Papers
shall impair such Right or be construed as a waiver thereof or an acquiescence
therein, nor shall any single or partial exercise of any such Right preclude
other or further exercise thereof, or the exercise of any other Right under the
Loan Papers or otherwise.

      9.05. Performance by Administrative Agent or any Lender. Should any
covenant of any Obligor fail to be performed in accordance with the terms of the
Loan Papers, Administrative Agent may, at its option, perform or attempt to
perform such covenant on behalf of such Obligor. Notwithstanding the foregoing,
it is expressly understood that neither Administrative Agent nor any Lender
assumes, and shall not ever have, except by express written consent of
Administrative Agent or such Lender, any liability or responsibility for the
performance of any duties or covenants of any Obligor.

      9.06. Expenditures. The Borrowers shall reimburse Administrative Agent and
each Lender for any reasonable sums spent by it in connection with the exercise
of any Right under Section 9.05 hereof. Such sums shall bear interest at the
lesser of (a) the Base Rate (whether or not in effect), plus 2.00% per annum and
(b) the Highest Lawful Rate, from five days after the date any Lender makes
demand to the Borrower for reimbursement of such amount until the date of
repayment by the Borrowers.

      9.07. Control. None of the covenants or other provisions contained in this
Agreement shall, or shall be deemed to, give Administrative Agent or any Lender
any Rights to exercise control over the affairs and/or management of any
Obligor, the power of Administrative Agent and each Lender being limited to the
Rights to exercise the remedies provided in this Article; provided, however,
that if Administrative Agent or any Lender becomes the owner of any partnership,
stock or other equity interest in any Person, whether through foreclosure or
otherwise, it shall be entitled to exercise such legal Rights as it may have by
being an owner of such stock or other equity interest in such Person.

                       ARTICLE X. THE ADMINISTRATIVE AGENT

      10.01. Authorization and Action. Each Lender hereby appoints and
authorizes Administrative Agent to take such action as Administrative Agent on
its behalf and to exercise such powers under this Agreement and the other Loan
Papers as are delegated to the Administrative Agent by the terms of the Loan
Papers, together with such powers as are reasonably incidental thereto. As to
any matters not expressly provided for by this Agreement and the other Loan
Papers (including without limitation enforcement or collection of the Notes),
Administrative Agent shall not be required to exercise any discretion or take
any action, but shall be required to act or to refrain from acting (and shall be
fully protected in so acting or refraining from acting) upon the instructions of
Majority Lenders (or all Lenders, if required under Section 11.01 hereof), and
such instructions shall be binding upon all Lenders; provided, however, that
Administrative Agent shall not be required to take any action which exposes
Administrative Agent to personal liability or which is contrary to any Loan
Papers or applicable Law. Administrative Agent agrees to give to each Lender
notice of each notice given to it by the Borrower pursuant to the terms of this
Agreement, and to distribute to each applicable Lender in like funds all amounts
delivered to Administrative Agent by the Borrowers for the individual account of
any Lender pro rata in accordance with the Applicable Specified Percentage, as
set forth in this Agreement. Functions of the Administrative Agent are
administerial in nature and in no event shall the Administrative Agent have a
fiduciary or trustee relationship in respect of any Lender by reason of this
Agreement or any other Loan Paper.

      10.02. Administrative Agent's Reliance, Etc. Neither Administrative Agent,
nor any of its directors, officers, agents, employees, or representatives shall
be liable for any action taken or omitted to be taken by it or them under or in
connection with this Agreement or any other Loan Paper, except for its or their
own gross negligence or willful misconduct. Without limitation of the generality
of the foregoing, Administrative Agent (a) may treat the payee of any Note as
the holder thereof until Administrative Agent receives written notice of the
assignment or transfer thereof signed by such payee and in form satisfactory to
Administrative Agent; (b) may consult with legal counsel (including counsel for
the Borrowers or any of their Subsidiaries), independent public accountants, and
other experts selected by it, and shall not be liable for any action taken or
omitted to be taken in good faith by it in accordance with the advice of such
counsel, accountants, or experts; (c) makes no warranty or representation to any
Lender and shall not be responsible to any Lender for any statements,
warranties, or representations made in or in connection with this Agreement or
any other Loan Papers; (d) shall not have any duty to ascertain or to inquire as
to the performance or observance of any of the terms, covenants, or conditions
of this Agreement or any other Loan Papers on the part of the Borrowers and
their Subsidiaries or to inspect the Property (including the books and records)
of the Borrowers or their Subsidiaries; (e) shall not be responsible to any
Lender for the due execution, legality, validity, enforceability, genuineness,
sufficiency, or value of this Agreement, any other Loan Papers, or any other
instrument or document furnished pursuant hereto; and (f) shall incur no
liability under or in respect of this Agreement or any other Loan Papers by
acting upon any notice, consent, certificate, or other instrument or writing
believed by it to be genuine and signed or sent by the proper party or parties.

      10.03. Bank of America, N.A. and Affiliates. With respect to its Domestic
Revolver Commitment, its Foreign Revolver Commitment, its Advances, and any Loan
Papers, Bank of America, N.A. has the same Rights under this Agreement as any
other Lender and may exercise









                                       63
<PAGE>   64

the same as though it were not Administrative Agent. Bank of America, N.A. and
its Affiliates may accept deposits from, lend money to, act as trustee under
indentures of, and generally engage in any kind of business with, any Obligor,
any Affiliate thereof, and any Person who may do business therewith, all as if
Bank of America, N.A. were not Administrative Agent and without any duty to
account therefor to any Lender.

      10.04. Lender Credit Decision. Each Lender acknowledges that it has,
independently and without reliance upon Administrative Agent or any other
Lender, and based on the financial statements referred to in Section 5.01(j),
Section 7.01 and Section 7.02 hereof and such other documents and information as
it has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement. Each Lender also acknowledges that it will, independently
and without reliance upon Administrative Agent or any other Lender and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement and the other Loan Papers.

      10.05. Indemnification by Lenders. Lenders shall indemnify Administrative
Agent, pro rata in accordance with each Lender's Total Specified Percentage,
from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses, or disbursements of any
kind or nature whatsoever which may be imposed on, incurred by, or asserted
against Administrative Agent in any way relating to or arising out of any Loan
Papers or any action taken or omitted by Administrative Agent thereunder,
including any negligence of Administrative Agent; provided, however, that no
Lender shall be liable for any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses, or disbursements
resulting from Administrative Agent's gross negligence or willful misconduct.
Without limitation of the foregoing, Lenders shall reimburse Administrative
Agent, pro rata in accordance with each Lender's Total Specified Percentage,
promptly upon demand for any out-of-pocket expenses (including reasonable
attorneys' fees) incurred by Administrative Agent in connection with the
preparation, execution, delivery, administration, modification, amendment, or
enforcement (whether through negotiation, legal proceedings or otherwise) of, or
legal and other advice in respect of rights or responsibilities under, the Loan
Papers. The indemnity provided in this Section 10.05 shall survive the
termination of this Agreement.

      10.06. Successor Administrative Agent. Administrative Agent may resign at
any time by giving written notice thereof to Lenders and the Borrower, and may
be removed at any time with or without cause by the action of all Lenders (other
than Administrative Agent, if it is a Lender). Upon any such resignation or
removal, Majority Lenders shall have the right to appoint a successor
Administrative Agent with the prior written consent of the Borrowers (which
shall not be unreasonably withheld), provided that, if there exists an Event of
Default that is continuing, no consent of the Borrowers shall be required. If no
successor Administrative Agent shall have been so appointed and shall have
accepted such appointment within thirty days after the retiring Administrative
Agent's giving of notice of resignation, then the retiring Administrative Agent
may, on behalf of Lenders, appoint a successor Administrative Agent, which shall
be a commercial bank organized under the Laws of the United States of America or
of any State thereof and having a combined capital and surplus of at least
$50,000,000. Upon the acceptance of any appointment as Administrative Agent
hereunder by a successor Administrative Agent, such successor









                                       64
<PAGE>   65

Administrative Agent shall thereupon succeed to and become vested with all the
Rights and duties of the retiring Administrative Agent, and the retiring
Administrative Agent shall be discharged from its duties and obligations under
the Loan Papers, provided that if the retiring or removed Administrative Agent
is unable to appoint a successor Administrative Agent, Administrative Agent
shall, after the expiration of a sixty day period from the date of notice, be
relieved of all obligations as Administrative Agent hereunder and the Lenders
shall act as the Administrative Agent. Notwithstanding any Administrative
Agent's resignation or removal hereunder, the provisions of this Article shall
continue to inure to its benefit as to any actions taken or omitted to be taken
by it while it was Administrative Agent under this Agreement.

                            ARTICLE XI. MISCELLANEOUS

      11.01. Amendments and Waivers. No amendment or waiver of any provision of
this Agreement or any other Loan Papers, nor consent to any departure by the
Borrower or any Obligor therefrom, shall be effective unless the same shall be
in writing and signed by the Borrower and the Administrative Agent with the
consent of the Majority Lenders, and then any such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given; provided, however, that no amendment, waiver, or consent shall (and the
result of action or failure to take action shall not) unless in writing and
signed by all of Lenders and Administrative Agent, (a) increase the Domestic
Revolver Commitment, (b) increase the Foreign Revolver Commitment (c) reduce any
principal, interest, fees, or other amounts payable hereunder, or waive or
result in the waiver of any Event of Default under Section 9.01(a) hereof, (d)
postpone any date fixed for any payment of principal, interest, fees, or other
amounts payable hereunder, (e) release or impair any collateral or guaranties
securing any Obligor's obligations hereunder, other than releases contemplated
hereby and by the other Loan Papers, (e) change the meaning of "Total Specified
Percentage", "Domestic Revolver Specified Percentage", "Foreign Revolver
Specified Percentage" or the number of Lenders required to take any action
hereunder, increase the amount of the "Commitment", "Domestic Revolver
Commitment", "Foreign Revolver Commitment", or "Letter of Credit Commitment",
extend the "Maturity Date", change the definition of "Majority Lenders", or (f)
amend this Section 11.01. No amendment, waiver, or consent shall affect the
Rights or duties of Administrative Agent under any Loan Papers, unless it is in
writing and signed by Administrative Agent in addition to the requisite number
of Lenders.

      11.02. Notices.

      (a) Manner of Delivery. All notices, communications and other materials to
be given or delivered under the Loan Papers shall, except in those cases where
giving notice by telephone is expressly permitted, be given or delivered in
writing. All written notices, communications and materials shall be sent by
registered or certified mail, postage prepaid, return receipt requested, by
telecopier, or delivered by hand. In the event of a discrepancy between any
telephonic notice and any written confirmation thereof, such written
confirmation shall be deemed the effective notice except to the extent
Administrative Agent, any Lender or the Borrower has acted in reliance on such
telephonic notice.

         (b) Addresses. All notices, communications and materials to be given or
delivered pursuant to this Agreement shall be given or delivered at the

      (iii) If to any Lender, to its address shown opposite its signature block
on the signature pages hereto, or on any Assignment and Acceptance, or in any

      (c) Effectiveness. Each notice, communication and any material to be given

      11.03. Parties in Interest. All covenants and agreements contained in this
Agreement and all other Loan Papers shall bind and inure to the benefit of the
respective successors and assigns of the parties hereto. Each Lender may from
time to time assign or transfer its interests hereunder pursuant to Section
11.04 hereof. Neither Borrower may assign or transfer its Rights or obligations
hereunder without the prior written consent of Administrative Agent.

      11.04. Assignments and Participations.

      (a) Each Lender (an "Assignor") may assign its Rights and obligations as a
Lender under the Loan Papers to one or more transferees pursuant to an
Assignment and Acceptance, so long as (i) each assignment shall be pro rata with
respect to the Assignor's Applicable Specified Percentage of a constant, and not
a varying percentage of all Rights and obligations thereunder, (ii) each
Assignor shall obtain in each case the prior written consent of Administrative
Agent and the Borrowers, in each case such consent of the Borrowers not to be
unreasonably withheld or delayed, provided that, in the event there exists an
Event of Default that is continuing, no consent of the Borrowers shall be
required to make an assignment, (iii) each Assignor shall in each case pay a
$3,500 processing fee to Administrative Agent and (iv) no such assignment is for
an amount less than $5,000,000 and in increments of $1,000,000 (and, if such
assignment is a partial assignment, no Lender shall hold less than $5,000,000
immediately after giving effect to any assignment). Assignments and other
transfers (except participations) with respect to each Lender's participation in
a given Letter of Credit may only be made with the prior written consent of the
Administrative Agent. Within five Business Days after Administrative Agent
receives notice of any such assignment, the Borrowers shall execute and deliver
to Administrative Agent, in exchange for the Notes issued to Assignor, new Notes
to the order of such Assignor and its assignee in amounts equal to their
respective Applicable Specified Percentages of the Commitments. Such new Notes
shall be dated the effective date of the assignment. It is specifically
acknowledged and agreed that on and after the effective date of each assignment,
the assignee shall be a party hereto and shall have the Rights and obligations
of a Lender under the Loan Papers.

      (b) Each Lender may sell participations to one or more Persons in all or
any of its Rights and obligations under the Loan Papers; provided, however, that
(i) such Lender's obligations under the Loan Papers shall remain unchanged, (ii)
such Lender shall remain solely responsible to the other parties hereto for the
performance of such obligations, (iii) such Lender shall remain the holder of
its Notes for all purposes of the Loan Papers, (iv) the participant shall be
granted the Right to vote on or consent to only those matters described in
Sections 11.01(a), (b), (c) and (d) hereof, (v) Obligors, the Administrative
Agent, and other Lenders shall continue to deal solely and directly with such
Lender in connection with their respective Rights and obligations under the Loan
Papers and (vi) no such participation is for an amount less than $5,000,000.

      (c) Any Lender may, in connection with any assignment or participation, or
proposed assignment or participation, disclose to the assignee or participant,
or proposed assignee or participant, any information relating to the Borrowers
and their Subsidiaries furnished to such Lender by or on behalf of the Borrowers
and their Subsidiaries.

         (d) Notwithstanding any other provision set forth in this Agreement,
(i) any Lender







                                       68
<PAGE>   69

may at any time create a security interest in all or any portion of its Rights
under this Agreement (including, without limitation, the Advances owing to it
and the Notes held by it) in favor of any Federal Reserve Bank in accordance
with Regulation A of the Board of Governors of the Federal Reserve System, (ii)
no participant of any Lender may further assign or participate any of its
interest in the Loan Papers to any Person (except as may be required by Law or a
Tribunal having authority over such participant), and (iii) no Lender (other
than Bank of America, N.A.) may assign any of its interest in the Loan Papers to
any Person (except as may be required by Law or a Tribunal having authority over
Bank of America, N.A.).

      11.05. Sharing of Payments. If, after and during the continuance of any
Event of Default, any Lender shall obtain any payment (whether voluntary,
involuntary, through the exercise of any Right of set-off, or otherwise) on
account of its Advances in excess of its pro rata share of payments made by the
Borrowers in accordance with such Lender's Total Specified Percentage, such
Lender shall forthwith purchase participations in Advances made by the other
Lenders as shall be necessary to share the excess payment pro rata in accordance
with each Lender's Total Specified Percentage with each of them; provided,
however, that if any of such excess payment is thereafter recovered from the
purchasing Lender, its purchase from each Lender shall be rescinded and each
Lender shall repay the purchase price to the extent of such recovery together
with a pro rata share of any interest or other amount paid or payable by the
purchasing Lender in respect of the total amount so recovered. The Borrower
agrees that any Lender so purchasing a participation from another Lender
pursuant to this Section 11.05 may, to the fullest extent permitted by Law,
exercise all its Rights of payment (including the Right of set-off) with respect
to such participation as fully as if such Lender were the direct creditor of the
Borrowers in the amount of such participation.

      11.06. Right of Set-off. Upon the occurrence and during the continuance of
any Event of Default, each Lender is hereby authorized (after prior written
notice to the Administrative Agent) at any time and from time to time, to the
fullest extent permitted by Law, to set-off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by such Lender to or for the credit or the
account of the Borrowers or any of their Subsidiaries against any and all of the
obligations of the Borrowers now or hereafter existing under this Agreement and
the other Loan Papers, whether or not Administrative Agent or any Lender shall
have made any demand under this Agreement or the other Loan Papers, and even if
such obligations are unmatured. Each Lender shall promptly notify the Borrowers
after any such set-off and application, provided that the failure to give such
notice shall not affect the validity of such set-off and application. The Rights
of each Lender under this Section 11.06 are in addition to other Rights
(including, without limitation, other Rights of set-off) which such Lender may
have.

      11.07. Costs, Expenses, and Taxes.

      (a) Notwithstanding anything to the contrary in the Loan Papers, the
Borrowers agrees to pay on demand (i) all costs and expenses of Administrative
Agent in connection with the preparation and negotiation of all Loan Papers,
including without limitation the reasonable fees and out-of-pocket expenses of
Special Counsel, FCC counsel, PUC counsel and local counsel, as appropriate,
(ii) all costs and expenses (including reasonable advisors' and attorneys' fees
and







                                       69
<PAGE>   70

expenses) of Administrative Agent in connection with the administration, any
interpretation, grant and perfection of any Lien, modification, amendment,
waiver, release of any Loan Papers, restructuring or work-out such that the
retainers established pursuant to Section 4.01(m) are maintained at the levels
established therein, (iii) all of the out-of-pocket expenses of each of the
Lenders in connection with the modification, amendment, waiver, release of any
Loan Papers, restructuring or work-out, and (iv) all costs and expenses
(including reasonable attorneys' fees and expenses) of Administrative Agent and
each Lender in connection with any collection of any portion of the Obligations
or the enforcement of any Loan Papers during the continuance of an Event of
Default. Any portion of a retainer established pursuant to Section 4.01(m) and
this Section 11.07(c) remaining unspent upon satisfaction of all Obligations
shall be promptly returned to Borrowers.

      (b) In addition, notwithstanding anything to the contrary in the Loan
Papers, the Borrowers shall pay any and all stamp, debt, and other Taxes payable
or determined to be payable in connection with any payment hereunder (other than
Taxes on the overall net income of Administrative Agent or any Lender or
franchise Taxes or Taxes on capital or capital receipts of Administrative Agent
or any Lender), or the execution, delivery, or recordation of any Loan Papers,
and agrees to save Administrative Agent and each Lender harmless from and
against any and all liabilities with respect to, or resulting from any delay in
paying or omission to pay any Taxes in accordance with this Section 11.07,
including any penalty, interest, and expenses relating thereto. All payments by
the Borrowers or their Subsidiaries under any Loan Papers shall be made free and
clear of and without deduction for any present or future Taxes (other than Taxes
on the overall net income of Administrative Agent or any Lender of any nature
now or hereafter existing, levied, or withheld, or franchise Taxes or Taxes on
capital or capital receipts of Administrative Agent or any Lender), including
all interest, penalties, or similar liabilities relating thereto. If the
Borrowers shall be required by Law to deduct or to withhold any Taxes from or in
respect of any amount payable hereunder (i) the amount so payable shall be
increased to the extent necessary so that, after making all required deductions
and withholdings (including Taxes on amounts payable to Administrative Agent or
any Lender pursuant to this sentence), Administrative Agent or any Lender
receives an amount equal to the sum it would have received had no such
deductions or withholdings been made, (ii) the Borrowers shall make such
deductions or withholdings, and (iii) the Borrowers shall pay the full amount
deducted or withheld to the relevant taxing authority in accordance with
applicable Law. Without prejudice to the survival of any other agreement of the
Borrowers hereunder, the agreements and obligations of the Borrowers contained
in this Section 11.07 shall survive the execution of this Agreement, termination
of the Commitment, repayment of the Obligations, satisfaction of each agreement
securing or assuring the Obligations and termination of this Agreement and each
other Loan Paper.

      11.08. Rate Provision. It is not the intention of any party to any Loan
Papers to make an agreement violative of the Laws of any applicable jurisdiction
relating to usury. In no event shall any Obligor or any other Person be
obligated to pay any amount in excess of the Maximum Amount. If Administrative
Agent or any Lender ever receives, collects or applies, as interest, any such
excess, such amount which would be excessive interest shall be deemed a partial
repayment of principal and treated hereunder as such; and if principal is paid
in full, any remaining excess shall be paid to the Borrowers or the other Person
entitled thereto. In determining whether or not the interest paid or





                                       70
<PAGE>   71

payable, under any specific contingency, exceeds the Maximum Amount, each
Obligor, Administrative Agent and each Lender shall, to the maximum extent
permitted under Applicable Laws, (a) characterize any nonprincipal payment as an
expense, fee or premium rather than as interest, (b) exclude voluntary
prepayments and the effect thereof, and (c) amortize, prorate, allocate and
spread in equal parts, the total amount of interest throughout the entire
contemplated term of the Obligations so that the interest rate is uniform
throughout the entire term of the Obligations; provided that if the Obligations
are paid and performed in full prior to the end of the full contemplated term
thereof, and if the interest received for the actual period of existence thereof
exceeds the Maximum Amount, Administrative Agent or Lenders, as appropriate,
shall refund to the Borrowers the amount of such excess or credit the amount of
such excess against the total principal amount owing, and, in such event,
neither Administrative Agent nor any Lender shall be subject to any penalties
provided by any Laws for contracting for, charging or receiving interest in
excess of the Maximum Amount. This Section 11.08 shall control every other
provision of all agreements among the parties to the Loan Papers pertaining to
the transactions contemplated by or contained in the Loan Papers.

      11.09. Severability. If any provision of any Loan Papers is held to be
illegal, invalid, or unenforceable under present or future Laws during the term
thereof, such provision shall be fully severable, the appropriate Loan Paper
shall be construed and enforced as if such illegal, invalid, or unenforceable
provision had never comprised a part thereof, and the remaining provisions
thereof shall remain in full force and effect and shall not be affected by the
illegal, invalid, or unenforceable provision or by its severance therefrom.
Furthermore, in lieu of such illegal, invalid, or unenforceable provision there
shall be added automatically as a part of such Loan Paper a legal, valid, and
enforceable provision as similar in terms to the illegal, invalid, or
unenforceable provision as may be possible.

      11.10. Exceptions to Covenants. No Obligor shall be deemed to be permitted
to take any action or to fail to take any action that is permitted as an
exception to any covenant in any Loan Papers, or that is within the permissible
limits of any covenant, if such action or omission would result in a violation
of any other covenant in any Loan Papers.

      11.11. Waivers. The Administrative Agent and the Lenders agree, on a one
time only basis, to waive any Defaults and Events of Default in existence on the
Closing Date.

      11.12. Counterparts. This Agreement and the other Loan Papers may be
executed in any number of counterparts, all of which taken together shall
constitute one and the same instrument. In making proof of any such agreement,
it shall not be necessary to produce or account for any counterpart other than
one signed by the party against which enforcement is sought.

      11.13. GOVERNING LAW; WAIVER OF JURY TRIAL.

      (A) THIS AGREEMENT AND ALL OTHER LOAN PAPERS (EXCEPT AS SUCH LOAN PAPERS
SPECIFY APPLICATION OF THE LAWS OF ANOTHER JURISDICTION) SHALL BE DEEMED TO BE
CONTRACTS MADE IN NEW YORK, NEW YORK, AND SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE







                                       71
<PAGE>   72

WITH THE LAWS OF THE STATE OF NEW YORK (EXCEPT TO THE EXTENT THE ADMINISTRATIVE
AGENT AND THE LENDERS HAVE GREATER RIGHTS OR REMEDIES UNDER FEDERAL LAW, WHETHER
AS NATIONAL BANKS OR OTHERWISE, IN WHICH CASE SUCH CHOICE OF NEW YORK LAW SHALL
NOT BE DEEMED TO DEPRIVE ADMINISTRATIVE AGENT AND LENDERS OF ANY SUCH RIGHTS AND
REMEDIES AS MAY BE AVAILABLE UNDER FEDERAL LAW) AND THE UNITED STATES OF
AMERICA. WITHOUT EXCLUDING ANY OTHER JURISDICTION, THE BORROWER AGREES THAT THE
FEDERAL COURTS OF NEW YORK LOCATED IN NEW YORK CITY, NEW YORK WILL HAVE
JURISDICTION OVER PROCEEDINGS IN CONNECTION HEREWITH. TO THE MAXIMUM EXTENT
PERMITTED BY LAW, THE BORROWERS EACH HEREBY WAIVE ANY RIGHT THAT IT MAY HAVE TO
A TRIAL BY JURY OF ANY DISPUTE (WHETHER A CLAIM IN TORT, CONTRACT, EQUITY, OR
OTHERWISE) ARISING UNDER OR RELATING TO THIS AGREEMENT, THE OTHER LOAN PAPERS,
OR ANY RELATED MATTERS, AND AGREES THAT ANY SUCH DISPUTE SHALL BE TRIED BEFORE A
JUDGE SITTING WITHOUT A JURY. EACH OF BORROWERS, THE ADMINISTRATIVE AGENT AND
EACH LENDER REPRESENTS THAT IT HAS KNOWINGLY AND VOLUNTARILY WAIVED ITS JURY
TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. IN THE EVENT OF
LITIGATION, A COPY OF THIS AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO A
TRIAL BY THE COURT.

      (B) TO THE EXTENT PERMITTED BY APPLICABLE LAW, THE BORROWER HEREBY WAIVES
PERSONAL SERVICE OF ANY LEGAL PROCESS UPON IT. THE BORROWERS AGREE THAT SERVICE
OF PROCESS MAY BE MADE UPON IT BY REGISTERED MAIL (RETURN RECEIPT REQUESTED)
DIRECTED TO THE BORROWER AT ITS ADDRESS DESIGNATED FOR NOTICE UNDER THIS
AGREEMENT AND SERVICE SO MADE SHALL BE DEEMED TO BE COMPLETED FIVE DAYS AFTER
DEPOSIT IN THE UNITED STATES MAIL. NOTHING IN THIS SECTION 11.12 SHALL AFFECT
THE RIGHT OF ADMINISTRATIVE AGENT OR ANY LENDER TO SERVE LEGAL PROCESS IN ANY
OTHER MANNER PERMITTED BY LAW.

      11.14. RELEASE

      THE BORROWERS, THE OBLIGORS AND THEIR SUBSIDIARIES, JOINTLY AND SEVERALLY,
FOR THEMSELVES AND THEIR RESPECTIVE SUCCESSORS AND ASSIGNS, EACH HEREBY
ACKNOWLEDGE THAT NONE OF THE BORROWERS, THE OBLIGORS AND THEIR SUBSIDIARIES,

AGENT OR ANY LENDER. EACH OF THE BORROWERS, THE OBLIGORS AND THEIR SUBSIDIARIES,
JOINTLY AND SEVERALLY, FOR THEMSELVES AND THEIR RESPECTIVE SUCCESSORS AND
ASSIGNS EACH HEREBY UNCONDITIONALLY AND IRREVOCABLY REMISES, ACQUITS, AND FULLY
AND FOREVER RELEASES AND DISCHARGES THE ADMINISTRATIVE AGENT AND EACH LENDER AND

LIABILITIES (COLLECTIVELY, THE "BORROWER CLAIMS") OF ANY NATURE WHATSOEVER,
WHETHER NOW KNOWN, SUSPECTED OR CLAIMED, WHETHER ARISING UNDER COMMON LAW, IN
EQUITY OR UNDER STATUTE, WHICH THE BORROWERS, THE OBLIGORS AND THEIR
SUBSIDIARIES, JOINTLY AND SEVERALLY, FOR THEMSELVES AND THEIR RESPECTIVE
SUCCESSORS AND ASSIGNS EVER HAD OR NOW HAVE AGAINST THE RELEASED LENDER PARTIES
WHICH MAY HAVE ARISEN AT ANY TIME ON OR PRIOR TO THE DATE OF THIS AGREEMENT AND
WHICH WERE IN ANY MANNER RELATED TO THIS AGREEMENT, ANY OTHER LOAN PAPERS OR THE
ENFORCEMENT OR ATTEMPTED ENFORCEMENT BY THE ADMINISTRATIVE AGENT OR ANY LENDER
OF RIGHTS, REMEDIES OR RECOURSES RELATED THERETO. THE BORROWERS, THE OBLIGORS
AND THEIR SUBSIDIARIES, JOINTLY AND SEVERALLY, FOR THEMSELVES AND THEIR
RESPECTIVE SUCCESSORS AND ASSIGNS COVENANT AND AGREE NEVER TO COMMENCE,
VOLUNTARILY AID IN ANY WAY, PROSECUTE OR CAUSE TO BE COMMENCED OR PROSECUTED

THE DATE OF THIS AGREEMENT AND WERE IN ANY MANNER RELATED TO THIS AGREEMENT, ANY
OTHER LOAN PAPERS OR THE TRANSACTIONS ASSOCIATED THEREWITH.

      11.15. Waiver of Civil Code ss.1542.

      To the extent that the foregoing release is a release as to which Section
1542 of the California Civil Code or similar provisions of other applicable law
applies, it is the intention of each of the signatories hereto that the
foregoing release shall be effective as a bar to any and all causes of action or
whatsoever character, nature and kind, known or unknown, suspected or
unsuspected, herein and above specified to be so barred. In furtherance of this
intention, the Borrowers hereby expressly waive any and all rights and benefits
conferred upon them by the provisions of Section 1542 of the California Civil
Code or similar provisions of other applicable law, and acknowledge that Section
1542 of the California Civil Code provides:

                  A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS
                  WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT






                                       73
<PAGE>   74

                  TO EXIST IN ITS FAVOR AT THE TIME OF EXECUTING
                  THE RELEASE, WHICH IF KNOW BY HIM MUST HAVE
                  MATERIALLY AFFECTED HIS SETTLEMENT WITH THE
                  DEBTOR.

      11.16. ENTIRE AGREEMENT. THIS AGREEMENT AND THE OTHER LOAN PAPERS
REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY
EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENT OF THE PARTIES.
THERE ARE NO ORAL AGREEMENTS BETWEEN THE PARTIES.

      11.17. Confidentiality. Each Lender agrees to keep information obtained by
it pursuant to the terms hereof or the terms of any other Loan Paper that is not
otherwise publicly available ("Confidential Information") confidential in
accordance with such Lender's customary procedures for handling confidential
information of this nature and in accordance with safe and sound banking
practices and agrees that it will only use such Confidential Information in
connection with the transactions contemplated by this Agreement and not disclose
any of such Confidential Information other than (a) to such Lenders and its
Affiliates' (other than an Affiliate which is a competitor of the Borrower or
its Subsidiaries) employees, counsel (in-house and outside), accountants,
consultants, representatives, professional advisors and agents so long as such
Person is advised of the confidentiality of such Confidential Information and
the limitation on its use under this Section 11.14, and needs to have knowledge
of such Confidential Information for such limited use, (b) to regulatory
officials, and in order to comply with any Applicable Law, or other law,
regulation or judicial order, or as requested or required by bank regulators or
auditors or other governmental authorities or Tribunals, (c) as reasonably
deemed necessary in connection with any investigation, legal process or
litigation, or (d) to assignees or participants or proposed assignees or
proposed participants of all or any part of this credit facility. The failure of
any Lender to comply with the provisions of this Section 11.14 shall not affect
the Obligations, or the obligation of the Borrowers to comply with the terms of
this Agreement and the other Loan Papers, or the validity of any assignment or
participation granted pursuant to the terms of this Agreement.

      11.18. Amendment, Restatement, Extension, Renewal and Increase. This
Agreement is a renewal and amendment and restatement of the Original Credit
Agreement, and, as such, except for the "Obligation" as defined in the Original
Credit Agreement (which shall survive, be renewed and restated by the terms of
this Agreement), all other terms and provisions supersede in their entirety the
Original Credit Agreement. This Agreement is being restated and amended in
accordance with the terms of Section 11.01 of the Original Credit Agreement. All
subordination agreements, security agreements, pledge agreements, mortgages,
deeds of trust and other documents and instruments granting any security
interest or assigning any interest in any assets of the Borrower or any
Subsidiary to secure the Obligation executed and delivered in connection with
this Agreement that restate any previously granted interest shall supersede any
subordination agreements, security agreements, pledge agreements, mortgages,
deeds of trust and other documents and instruments granting any security
interest or assigning any interest in any assets of the Borrower or any
Subsidiary that were executed and delivered in connection with the Original
Credit Agreement (the "Original Security Documents"), except for the Liens
created under the Original Security Documents







                                       74
<PAGE>   75

which shall remain valid, binding and enforceable Liens against the Borrower,
the Subsidiaries and each of the other Persons granting any such Liens. All
other Original Security Documents shall continue to secure the Obligations as
herein defined, and shall be in full force and effect.
