$100,000).

     Section 2.10. Interest. (a) Interest shall accrue on the outstanding and
unpaid principal amount of each Loan for the period from and including the date
of such Loan to but excluding the date such Loan is due at the following rates
per annum: (i) for a Variable Rate Loan, at a variable rate per annum equal to
the Variable Rate plus the Interest Margin and (ii) for a Fixed Rate Loan, at a
fixed rate equal to the LIBO Rate or NIBO Rate plus the Interest Margin. If an
Event of Default shall exist, interest shall accrue on the outstanding principal
amount of any Loan and any other amount payable by the Borrower or the
Subsidiary Borrower hereunder, under any Note or under any other Facility
Document to the fullest extent permitted by law from and including such due date
to but excluding the date such amount is paid in full or such Event of Default
is cured at the Default Rate.

          (b) The interest rate on each Variable Rate Loan shall change when the
Variable Rate changes and interest on each such Variable Rate Loan shall be
calculated on the basis of a year of 365/366 days for the actual number of days
elapsed. Interest on each Fixed Rate Loan shall be calculated on the basis of a
year of 360 days for the actual number of days elapsed. Promptly after the
determination of any interest rate provided for herein or any change therein,
the Administrative Agent shall notify the Borrower, the Subsidiary Borrower and
the Lenders.

          (c) Accrued interest shall be due and payable in arrears upon any
repayment of principal or conversion and (i) for each Variable Rate Loan, on the
fifteenth day of each March, June, September and December commencing the first
such date after such Variable Rate Loan; and (ii) for each Fixed Rate Loan, on
the last day of the Interest Period with respect thereto and, in the case of an
Interest Period greater than three months or 90 days, at three-month intervals
after the first day of such Interest Period; provided that interest accruing at
the Default Rate shall be due and payable from time to time on demand of the
Administrative Agent.

     Section 2.11. Fees. (a) The Borrower shall pay to the Administrative Agent
for the account of each Lender a commitment fee on the daily average of the
unused Revolving Credit Commitments to the Borrower of such Lender minus such
Lender's pro rata share of Letter of Credit Obligations for the period from and
including the date hereof to the earlier of the date all of the Revolving Credit
Commitments are terminated or the Revolving Credit Termination Date at a rate
per annum equal to 1/4 of one percent, calculated in each case on the basis of a
year of 360 days for the actual number of days elapsed. The Subsidiary Borrower
shall pay to the Administrative Agent for the account of each Lender a
commitment fee on the daily average of the unused Swingline Commitments to the
Subsidiary Borrower of such Lender for the period from and including the date
hereof to the earlier of the date all of the Swingline Commitments are
terminated or the Swingline Termination Date at a rate per annum equal to 1/4 of
one percent, calculated in each case on the basis of a year of 360 days for the
actual number of days elapsed. The accrued commitment fees shall be due and
payable in arrears upon any reduction or termination of the Revolving Credit
Commitments or the Swingline Commitments, as


                                       27

<PAGE>   33

applicable, and on the fifteenth day of each March, June, September and
December, commencing on the first such date after the Closing Date.

          (b) The Borrower shall pay to the Administrative Agent for its own
account the fees set forth in the fee letter dated as of the Closing Date
between the Borrower and the Administrative Agent.

     Section 2.12. Payments Generally. All payments under this Agreement, the
Revolving Credit Notes and the other Facility Documents shall be made in Dollars
and all payments under the Swingline Notes shall be made in Norwegian Krone, in
each case in immediately available funds not later than 11:00 a.m. New York, New
York time on the relevant dates specified above or in such Facility Document
(each such payment made after such time on such due date to be deemed to have
been made on the next succeeding Banking Day) by, unless the Administrative
Agent agrees to accept payment by other means, the debiting by the
Administrative Agent for the account of the applicable Lending Office of each
Lender, or by any Lender for whose account any such payment is to be made, of
the amount of any such payment from any ordinary deposit account of the Borrower
or the Subsidiary Borrower, as applicable, with the Administrative Agent or such
Lender, as the case may be, and the Administrative Agent so doing shall promptly
notify the Borrower or the Subsidiary Borrower, as applicable, and any Lender so
doing shall promptly notify the Administrative Agent which in turn shall
promptly notify the Borrower or the Subsidiary Borrower, as applicable. The
Borrower or the Subsidiary Borrower, as applicable, shall, at the time of making
each optional payment under this Agreement, any Note or any other Facility
Document, specify to the Administrative Agent the principal or other amount
payable by the Borrower or the Subsidiary Borrower under this Agreement, such
Note or such other Facility Document to which such payment is to be applied (and
in the event that it fails to so specify, or if a Default or Event of Default
has occurred and is continuing, the Administrative Agent may apply such payment
as it may elect in its sole discretion (subject to Section 11.16)). If the due
date of any payment under this Agreement, any Note or any other Facility
Document would otherwise fall on a day which is not a Banking Day, such date
shall be extended to the next succeeding Banking Day and interest shall be
payable for any principal so extended for the period of such extension. Each
payment received by the Administrative Agent hereunder, under any Note or any
other Facility Document for the account of a Lender shall be paid promptly to
such Lender, in immediately available funds, for the account of such Lender's
Lending Office.


          ARTICLE 3. THE LETTERS OF CREDIT.

     Section 3.01. Letters of Credit. (a) Subject to the terms and conditions of
this Agreement, the Issuing Lender, on behalf of the Lenders, and in reliance on
the agreement of the Lenders set forth in Section 3.04, agrees to issue on any
Banking Day prior to the Revolving Credit Termination Date, for the account of
the Borrower, irrevocable documentary and standby letters of credit or bank
guarantees in such


                                       28

<PAGE>   34

form as may from time to time be approved by the Issuing Lender acting
reasonably (together with the applications therefor, the "Letters of Credit");
provided that on the date of the issuance of any Letter of Credit, and after
giving effect to such issuance, the Letter of Credit Obligations shall not
exceed the Letter of Credit Availability.

          (b) Each Letter of Credit shall (i) have an expiry date no later than
the earlier of (A) one year from the date of issuance provided that such Letter
of Credit may automatically renew for subsequent one year terms upon the failure
of the Issuing Lender to provide sixty days' prior written notice of termination
to the Borrower and (B) the Revolving Credit Termination Date, (ii) be
denominated in Dollars, (iii) be in a minimum face amount of $100,000 and (iv)
provide for the payment of sight drafts when presented for honor thereunder in
accordance with the terms thereof and when accompanied by the documents
described therein or when such documents are presented, as the case may be.

     Section 3.02. Purposes. The Borrower shall use the Letters of Credit for
the purpose of securing obligations incurred in the ordinary course of business.

     Section 3.03. Procedures for Issuance of Letters of Credit. The Borrower
may from time to time request that the Issuing Lender issue a Letter of Credit
by delivering to the Issuing Lender at its address for notices specified herein
an application therefor in such form as may from time to time be approved by the
Issuing Lender acting reasonably, completed to the reasonable satisfaction of
the Issuing Lender, and such other certificates, documents and other papers and
information as the Issuing Lender may reasonably request. Upon receipt of any
application, the Issuing Lender will process such application and the
certificates, documents and other papers and information delivered to it in
connection therewith in accordance with its customary procedures and shall
promptly issue the requested Letter of Credit in such customized form as may
reasonably be requested by the Borrower (but in no event shall the Issuing
Lender issue any Letter of Credit later than five Banking Days after receipt of
the application therefor and all such other certificates, documents and other
papers and information relating thereto) by issuing the original of such Letter
of Credit to the beneficiary thereof or as otherwise may be agreed by the
Issuing Lender and the Borrower. The Issuing Lender shall furnish a copy of such
Letter of Credit to the Borrower promptly following the issuance thereof.

     Section 3.04. Participating Interests. In the case of each Letter of
Credit, effective as of the date of the issuance thereof, the Issuing Lender
agrees to allot and does allot to each other Lender, and each such Lender
severally and irrevocably agrees to take and does take a Participating Interest
in such Letter of Credit in a percentage equal to such Lender's pro rata share
of the Letter of Credit Obligations (calculated based on its Revolving Credit
Commitment Percentage). On the date that any Lender becomes a party to this
Agreement in accordance with Section 12.05, Participating Interests in any
outstanding Letter of Credit held by the transferor Lender from which such
transferee Lender acquired its interest hereunder shall be


                                       29

<PAGE>   35

proportionately reallotted between such transferee Lender and such transferor
Lender. Each Participating Lender hereby agrees that its obligation to
participate in each Letter of Credit, and to pay or to reimburse the Issuing
Lender for its participating share of the drafts drawn thereunder, is absolute,
irrevocable and unconditional and shall not be affected by any circumstances
whatsoever, including, without limitation, the occurrence and continuance of any
Default or Event of Default, and that each such payment shall be made without
any offset, abatement, withholding or other reduction whatsoever.

     Section 3.05. Payments. (a) In order to induce the Issuing Lender to issue
the Letters of Credit, the Borrower hereby agrees to reimburse the Issuing
Lender, unless such Reimbursement Obligation has been accelerated pursuant to
Section 10.02, by not later than 1:00 p.m., New York City time, on each date
that the Borrower has been notified by the Issuing Lender that any draft
presented under any Letter of Credit is paid by the Issuing Lender, for (i) the
amount of the draft paid by the Issuing Lender and (ii) the amount of any taxes,
fees, charges or other reasonable costs or expenses whatsoever incurred by the
Issuing Lender in connection with any payment made by the Issuing Lender under,
or with respect to, such Letter of Credit. Each such payment shall, subject to
the next sentence hereof, be made to the Issuing Lender at its office specified
in Section 12.06, in lawful money of the United States and in immediately
available funds by not later than 1:00 p.m., New York City time, on the day that
payment is made by the Issuing Lender (or, if such drawing occurs after 1:00
p.m. New York City time, on the next succeeding Banking Day). If such payment is
not made in full, all amounts remaining unpaid by the Borrower under this
Section 3.05 shall, to the extent otherwise permitted hereunder, automatically
be deemed to be a borrowing as Revolving Credit Loans bearing interest at the
Variable Rate plus the Interest Margin. Except as otherwise permitted by the
preceding sentence, interest on any and all amounts remaining unpaid by the
Borrower under this Section 3.05 at any time from the date such amounts become
payable (whether at stated maturity, by acceleration or otherwise) until payment
in full shall be payable to the Issuing Lender on demand at a fluctuating rate
per annum equal to the Default Rate.

          (b) In the event that the Issuing Lender makes a payment (a "Letter of
Credit Funding") under any Letter of Credit and is not reimbursed in full
therefor on the date of such Letter of Credit Funding, in accordance with the
terms hereof, the Issuing Lender will promptly through the Administrative Agent
notify each Participating Lender that acquired its Participating Interest in
such Letter of Credit from the Issuing Lender. No later than the close of
business on the date such notice is given if such notice is given, each such
Participating Lender will transfer to the Administrative Agent, for the account
of the Issuing Lender, in immediately available funds, an amount equal to such
Participating Lender's pro rata share of the unreimbursed portion of such Letter
of Credit Funding (calculated based on its Revolving Credit Commitment
Percentage), together with interest, if any, accrued


                                       30

<PAGE>   36

thereon from and including the date of such transfer at a rate per annum equal
to the Federal Funds Rate plus two percent (2%).

          (c) Whenever, at any time after the Issuing Lender has made a Letter
of Credit Funding and has received from any Participating Lender such
Participating Lender's pro rata share of the unreimbursed portion of such Letter
of Credit Funding, the Issuing Lender receives any reimbursement on account of
such unreimbursed portion or any payment of interest on account thereof, the
Issuing Lender will distribute to the Administrative Agent, for the account of
such Participating Lender, its pro rata share thereof; provided, however, that
in the event that the receipt by the Issuing Lender of such reimbursement or
such payment of interest (as the case may be) is required to be returned, such
Participating Lender will promptly return to the Administrative Agent, for the
account of the Issuing Lender, any portion thereof previously distributed by the
Issuing Lender to it.

     Section 3.06. Further Assurances. The Borrower hereby agrees to do and
perform any and all acts and to execute any and all further instruments from
time to time reasonably requested by the Issuing Lender more fully to effect the
purposes of this Agreement and the issuance of the Letters of Credit hereunder.

     Section 3.07. Obligations Absolute. The payment obligations of the Borrower
under Section 3.05 shall be unconditional and irrevocable and shall be paid
strictly in accordance with the terms of this Agreement under all circumstances,
including, without limitation, the following circumstances:

          (a) the existence of any claim, set-off, defense or other right which
the Borrower may have at any time against any beneficiary, or any transferee, of
any Letter of Credit (or any Persons for whom any such beneficiary or any such
transferee may be acting), the Issuing Lender or any Participating Lender, or
any other Person, whether in connection with this Agreement, any other Facility
Document, the transactions contemplated herein, or any unrelated transaction;

          (b) any statement or any other document presented under any Letter of
Credit proving to be forged, fraudulent, invalid or insufficient in any respect
or any statement therein being untrue or inaccurate in any respect, provided
that this subparagraph (b) shall not relieve the Issuing Lender of any liability
determined to have resulted from the gross negligence or willful misconduct of
the Issuing Lender;

          (c) payment by the Issuing Lender under any Letter of Credit against
presentation of a draft or certificate which does not comply with the terms of
such Letter of Credit, provided that this subparagraph (c) shall not relieve the
Issuing Lender of any liability determined to have resulted from the gross
negligence or willful misconduct of the Issuing Lender; or


                                       31

<PAGE>   37

          (d) any other circumstances or happening whatsoever, whether or not
similar to any of the foregoing, provided that this subparagraph (d) shall not
relieve the Issuing Lender of any liability determined to have resulted from the
gross negligence or willful misconduct of the Issuing Lender.

     Section 3.08. Cash Collateral Account. If the Commitments are duly
terminated and all amounts owing under this Agreement, the Notes and the
Reimbursement Obligations become due and payable pursuant to Section 10, the
Borrower shall deposit with the Administrative Agent, on the date such
obligations become due and payable, an amount in cash or Domestic Cash
Equivalents equal to the Letter of Credit Obligations as of such date and the
Letter of Credit fees in accordance with Section 3.09. Such amount shall be
deposited in a cash collateral account to be established by the Administrative
Agent, for the benefit of the Issuing Lender and the Participating Lenders, and
shall constitute collateral security for the Letter of Credit Obligations and
other amounts owing hereunder. All amounts in such cash collateral account shall
be maintained pursuant to a cash collateral account agreement which shall grant
to the Administrative Agent a security interest in all such funds and in any
investments made therewith or proceeds thereof to secure payment to the
Administrative Agent of Reimbursement Obligations with respect to outstanding
Letters of Credit. In the event that the Administrative Agent makes any Letter
of Credit Funding, the Administrative Agent may withdraw funds on deposit to
make reimbursement of such Letter of Credit Funding, in an amount equal to such
Letter of Credit Funding. Upon payment by the Borrower of all Reimbursement
Obligations with respect to Letters of Credit or the termination or other
expiration of all Letters of Credit, remaining funds on deposit in the cash
collateral account shall be returned promptly to the Borrower.

     Section 3.09. Letter of Credit Fees. (a) The Borrower agrees to pay the
Administrative Agent, for the account of the Issuing Lender and the
Participating Lenders, a non-refundable letter of credit fee of (a) with respect
to each documentary Letter of Credit, an amount equal to one-half of one percent
of the face amount under such documentary Letter of Credit payable on payment
thereof and (b) with respect to each standby Letter of Credit, an amount
computed at the rate of one and one quarter percent per annum of the aggregate
undrawn amount under each standby Letter of Credit, calculated on the basis of a
year of 360 days for the actual number of days elapsed, payable in arrears on
the fifteenth day of each March, June, September and December, commencing on the
first such date after the Closing Date.

          (b) The Borrower agrees to pay the Issuing Lender, for its own
account, its normal and customary administration, amendment, transfer, payment
and negotiation fees charged in connection with its issuance and administration
of letters of credit.

          ARTICLE 4. YIELD PROTECTION; ILLEGALITY; ETC.

     Section 4.01. Additional Costs. (a) The Borrower or the Subsidiary
Borrower, as applicable, shall pay directly to each Lender from time to time on
demand such amounts as such Lender may determine (and reasonably substantiate)
to be necessary to compensate it for any costs which such Lender determines are
attributable to its making or maintaining any Fixed Rate Loans under this
Agreement or its Notes or its obligation to make any such Fixed Rate Loans
hereunder, or any reduction in any amount receivable by such Lender hereunder in
respect of any such Fixed Rate Loans or such obligation (such increases in costs
and reductions in amounts receivable being herein called "Additional Costs"),
resulting from any Regulatory Change relating to any such Fixed Rate Loans or
such obligation which: (i) changes the basis of taxation of any amounts payable
to such Lender under this Agreement or its Notes in respect of any of such Fixed
Rate Loans (other than taxes imposed on the overall net income of such Lender or
of its Lending Office for any of such Fixed Rate Loans by the jurisdiction in
which such Lender has its principal office or such Lending Office); or (ii)
imposes or modifies any reserve, special deposit, deposit insurance or
assessment, minimum capital, capital ratio or similar requirements relating to
any extensions of credit or other assets of, or any deposits with or other
liabilities of, such Lender (including any of such Fixed Rate Loans or any
deposits referred to in the definition of "LIBO Base Rate" or "NIBO Base Rate"
in Section 1.01); or (iii) imposes any other condition affecting this Agreement
or its Notes (or any of such extensions of credit or liabilities). Each Lender
will notify the Borrower or the Subsidiary Borrower, as applicable, of any event
occurring after the date of this Agreement which will entitle such Lender to
compensation pursuant to this Section 4.01(a) as promptly as practicable after
it obtains knowledge thereof and determines to request such compensation. If any
Lender requests compensation from the Borrower or the Subsidiary Borrower, as
applicable, under this Section 4.01(a), or under Section 4.01(c), the Borrower
or the Subsidiary Borrower, as applicable, may, by notice to such Lender (with a
copy to the Administrative Agent), require that such Lender's affected Fixed
Rate Loans with respect to which such compensation is requested be converted in
accordance with Section 4.04. If any taxes are imposed for which the Borrower or
the Subsidiary Borrower, as applicable, would be required to make a payment
under this Section 4.01, the applicable Lender shall use its best efforts to
avoid or reduce such taxes by taking any appropriate action (including, without
limitation, assigning its rights hereunder to a related entity or a different
Lending Office).

          (b) Without limiting the effect of the foregoing provisions of this
Section 4.01, in the event that, by reason of any Regulatory Change, any Lender
either (i) incurs Additional Costs based on or measured by the excess above a
specified level of the amount of a category of deposits or other liabilities of
such Lender which includes deposits by reference to which the interest rate on
Fixed Rate Loans is determined as provided in this Agreement or a category of
extensions of credit or other assets of such Lender which includes Fixed Rate
Loans or (ii) becomes


                                       33

<PAGE>   39

subject to restrictions on the amount of such a category of liabilities or
assets which it may hold, then, if such Lender so elects by notice to the
Borrower or the Subsidiary Borrower, as applicable (with a copy to the
Administrative Agent), the obligation of such Lender to make or renew Fixed Rate
Loans, and to convert Variable Rate Loans to Fixed Rate Loans hereunder shall be
suspended until the date such Regulatory Change ceases to be in effect (and all
affected Fixed Rate Loans held by such Lender then outstanding shall be
converted in accordance with Section 4.04).

          (c) Without limiting the effect of the foregoing provisions of this
Section 4.01 (but without duplication), the Borrower or the Subsidiary Borrower,
as applicable, shall pay directly to each Lender from time to time on request
such amounts as such Lender may determine to be necessary to compensate such
Lender for any costs which it determines are attributable to the maintenance by
it or any of its affiliates pursuant to any law or regulation of any
jurisdiction or any interpretation, directive or request (whether or not having
the force of law and whether in effect on the date of this Agreement or
thereafter) of any court or governmental or monetary authority of capital in
respect of its Loans hereunder, its obligation to make Loans hereunder or its
obligation to issue, or participate in, any Letter of Credit (such compensation
to include, without limitation, an amount equal to any reduction in return on
assets or equity of such Lender to a level below that which it could have
achieved but for such law, regulation, interpretation, directive or request).
Each Lender will notify the Borrower or the Subsidiary Borrower, as applicable,
if it is entitled to compensation pursuant to this Section 4.01(c) as promptly
as practicable after it determines to request such compensation.

          (d) Determinations and allocations by a Lender for purposes of this
Section 4.01 of the effect of any Regulatory Change pursuant to subsections (a)
or (b), or of the effect of capital maintained pursuant to subsection (c), on
its costs of making or maintaining Loans, its obligation to make Loans or its
obligation to issue, or participate in, any Letter of Credit, or on amounts
receivable by, or the rate of return to, it in respect of Loans or such
obligation, and of the additional amounts required to compensate such Lender
under this Section 4.01, shall be conclusive, provided that such determinations
and allocations are made on a reasonable basis.

     Section 4.02. Limitation on Fixed Rate Loans. Anything herein to the
contrary notwithstanding, if:

          (a) the Administrative Agent determines (which determination shall be
conclusive) that quotations of interest rates for the relevant deposits referred
to in the definition of "LIBO Base Rate" or "NIBO Base Rate" in Section 1.01 are
not being provided in the relevant amounts or for the relevant maturities for
purposes of determining the rate of interest for any Fixed Rate Loans as
provided in this Agreement; or


                                       34

<PAGE>   40

          (b) the Required Lenders determine (which determination shall be
conclusive) and notify the Administrative Agent that the relevant rates of
interest referred to in the definition of "Fixed Base Rate" in Section 1.01 upon
the basis of which the rate of interest for any Fixed Rate Loans is to be
determined do not adequately cover the cost to the Lenders of making or
maintaining such Fixed Rate Loans; or

          (c) in the case of Fixed Rate Loans denominated in Norwegian Krone,
any Lender shall determine (which determination shall be conclusive) and notify
the Administrative Agent that Norwegian Krone is not available in the relevant
amounts or for the relevant period, or that a change in national or
international controls has occurred which would, in the opinion of such Lender,
make it impracticable for such Lender to make, fund or maintain its Fixed Rate
Loans to be made in Norwegian Krone or for the Subsidiary Borrower to pay the
principal of or interest on such Fixed Rate Loans as provided in this Agreement;

then the Administrative Agent shall give the Borrower or the Subsidiary
Borrower, as applicable, and each Lender prompt notice thereof, and so long as
such condition remains in effect, the Lenders shall be under no obligation to
make or renew affected Fixed Rate Loans or to convert Variable Rate Loans into
affected Fixed Rate Loans and the Borrower or the Subsidiary Borrower, as
applicable, shall, on the last day(s) of the then current Interest Period(s) for
the outstanding affected Fixed Rate Loans, either prepay such Fixed Rate Loans
or convert such Fixed Rate Loans into Variable Rate Loans in accordance with
Section 2.05.

     Section 4.03. Illegality. Notwithstanding any other provision in this
Agreement, in the event that it becomes unlawful for any Lender or its Lending
Office to honor its obligation to make, maintain or renew Fixed Rate Loans
hereunder or convert Variable Rate Loans into Fixed Rate Loans, then such Lender
shall promptly notify the Borrower or the Subsidiary Borrower, as applicable,
thereof (with a copy to the Administrative Agent) and such Lender's obligation
to make or renew Fixed Rate Loans and to convert other Variable Rate Loans into
Fixed Rate Loans hereunder shall be suspended until such time as such Lender may
again make, renew, or convert and maintain such Fixed Rate Loans and such
Lender's outstanding Fixed Rate Loans, as the case may be, shall be converted in
accordance with Section 4.04.

     Section 4.04. Certain Conversions Pursuant to Sections 4.01 and 4.03. If
Fixed Rate Loans are to be converted pursuant to Section 4.01 or 4.03, such
Lender's Fixed Rate Loans shall be automatically converted into Variable Rate
Loans on the last day(s) of the then current Interest Period(s) for such
Lender's Fixed Rate Loans (or, in the case of a conversion required by Section
4.01 or 4.03, on such earlier date as such Lender may specify to the Borrower
with a copy to the Administrative Agent) and, unless and until such Lender gives
notice as provided below that the circumstances specified in Section 4.01 or
4.03 which gave rise to such conversion no longer exist:

                                       35

<PAGE>   41

          (a) to the extent that such Lender's Fixed Rate Loans have been so
converted, all payments and prepayments of principal which would otherwise be
applied to such Lender's Fixed Rate Loans shall be applied instead to its
Variable Rate Loans; and

          (b) all Fixed Rate Loans which would otherwise be made or renewed by
such Lender as Fixed Rate Loans shall be made instead as Variable Rate Loans and
all Variable Rate Loans of such Lender which would otherwise be converted into
Fixed Rate Loans shall remain as Variable Rate Loans.

     If such Lender gives notice to the Borrower or the Subsidiary Borrower, as
applicable (with a copy to the Administrative Agent) that the circumstances
specified in Section 4.01 or 4.03 which gave rise to the conversion of such
Lender's Fixed Rate Loans pursuant to this Section 4.04 no longer exist (which
such Lender agrees to do promptly upon such circumstances ceasing to exist) at a
time when Fixed Rate Loans are outstanding, such Lender's Variable Rate Loans
shall be automatically converted, on the first day(s) of the next succeeding
Interest Period(s) for such outstanding Fixed Rate Loans to the extent necessary
so that, after giving effect thereto, all Fixed Rate Loans held by the Lenders
holding Fixed Rate Loans and by such Lender are held pro rata (as to principal
amounts, types, classes and Interest Periods) in accordance with their
respective Commitments.

     Section 4.05. Certain Compensation. The Borrower and the Subsidiary
Borrower, as applicable, shall pay to the Administrative Agent for the account
of each Lender, upon the request of such Lender through the Administrative
Agent, such amount or amounts as shall be sufficient (in the reasonable opinion
of such Lender) to compensate it for any loss, cost or expense which such Lender
determines is attributable to:

          (a) any payment, prepayment, conversion or renewal of a Fixed Rate
Loan made by such Lender on a date other than the last day of an Interest Period
for such Fixed Rate Loan (whether by reason of acceleration or otherwise); or

          (b) any failure by the Borrower or the Subsidiary Borrower, as
applicable, to borrow, convert into or renew a Fixed Rate Loan to be made,
converted into or renewed by such Lender on the date specified therefor in the
relevant notice under Sections 2.04, 2.05 or 2.07, as the case may be.

     Without limiting the foregoing, such compensation shall include an amount
equal to the present value of the excess, if any, of: (i) the amount of interest
which otherwise would have accrued on the principal amount so paid, prepaid,
converted or renewed or not borrowed, converted or renewed for the period from
and including the date of such payment, prepayment or conversion or failure to
borrow, convert or renew to but excluding the last day of the then current
Interest Period for such Fixed Rate Loan (or, in the case of a failure to
borrow, convert or renew, to but excluding


                                       36

(ii) the amount of interest (as reasonably determined by such Lender) such
Lender would have bid in the London interbank market (if such Loan is a Fixed
Rate Loan) for Dollar or Norwegian Krone deposits for amounts comparable to such
principal amount and maturities comparable to such period. A determination of

conclusive absent manifest error.

covenants and agrees that:

Document, including without limitation amounts payable under Section 4.06(b),
shall be made without any set-off or counterclaim and free and clear of and
without reduction by reason of, all present and future income, stamp,

indemnify each Lender against, and reimburse each Lender on demand for, any
Taxes and any loss, liability, claim or expense, including interest, penalties

which such Lender shall actually receive or utilize), which such Lender may
incur at any time arising out of or in connection with any failure of the
Borrower or the Subsidiary Borrower, as applicable, to make any payments of
Taxes when due;

Subsidiary Borrower, as applicable, to such Lender under this Agreement, its
Note held by such Lender or under any other Facility Document;

          (d) The Borrower and the Subsidiary Borrower, as applicable, shall
furnish to each Lender the official tax receipts in respect of each payment of
Taxes required under this Section 4.06 within 30 days after the date such
payment is due pursuant to applicable law, and the Borrower and the Subsidiary
Borrower, as applicable, shall promptly furnish to each Lender at its request
any other information, documents and receipts that such Lender may, in its
reasonable discretion from time to time, require to establish to its
satisfaction that full and timely payment has been made of all Taxes required to
be paid under this Section 4.06; and

          (e) In the event that the payments by the Borrower or the Subsidiary
Borrower, as applicable, hereunder become exempt from or not subject to Taxes,
the Borrower or the Subsidiary Borrower, as applicable, will, upon the
reasonable request of any Lender, furnish to such Lender either a certificate

which any Obligor is a party is, or when delivered under this Agreement will be,
a legal, valid and binding obligation of such Obligor enforceable against such
Obligor in accordance with its terms, except to the extent that such enforcement
may be limited by applicable bankruptcy, insolvency and other similar laws
affecting creditors' rights generally and general principles of equity
(regardless of whether such enforceability is considered in a proceeding at law
or in equity).

     Section 6.04. Litigation. Except as set forth on SCHEDULE 6.04, there are
no material actions, suits or proceedings pending or, to the knowledge of any
Obligor,

          (e) Except as set forth in the consolidated balance sheet of the LCC
Consolidated Entities as of September 30, 1997, there are no liabilities of any
LCC Consolidated Entity, fixed or contingent, which are material but are not
reflected in such financial statements or in such notes and which would be
required to be recorded in such financial statements or notes in accordance with
GAAP. No information, exhibit or report furnished by any LCC Consolidated Entity
to the Administrative Agent or any Lender in connection with the negotiation of
this Agreement or any other Facility Document contained any material
misstatement of fact or omitted to state a material fact or any fact necessary
to make the statements contained therein not materially misleading. Since
September 30, 1997, there has been no change which could reasonably be expected
to have a Material Adverse Effect.

     Section 6.06. Ownership and Liens. Each of the LCC Consolidated Entities
has title to, or valid leasehold interests in, all of its Properties reflected
in the financial statements referred to in Section 6.05 (other than any
Properties disposed of in the ordinary course of business), and none of the
Properties owned or leased by any LCC Consolidated Entity is subject to any
Lien, except as may be permitted hereunder and except for the Liens created by
the Security Documents; provided that no Obligor is making any representation or
warranty with respect to Liens affecting the fee interest in real Property
leased to any LCC Consolidated Entity and not owned by another LCC Consolidated
Entity.

     Section 6.07. Taxes. Except as set forth on SCHEDULE 6.07 or as otherwise
permitted under Section 7.06, each of the LCC Consolidated Entities has filed
(or obtained extensions for) all tax returns (domestic, foreign, federal, state
and local) required to be filed and has paid or provided adequate reserves for
all taxes, assessments and governmental charges and levies shown thereon to be
due, including interest and penalties. The charges, accruals and reserves on the
books of the LCC Consolidated Entities in respect of taxes, assessments and
other governmental charges are adequate.

     Section 6.08. ERISA. Each Domestic Plan, Foreign Plan and, to the best
knowledge of each Obligor, Multiemployer Plan, is in compliance in all material
respects with, and has been administered in all material respects in compliance
with, the applicable provisions of ERISA, the Code and any other applicable
domestic, foreign, federal, state or local law, and no event or condition is

                                       43

<PAGE>   49

furnish a report to the Lenders in accordance with Section 7.08(j). Each of the

to acquire any shares of stock or any other security or interest in any other
Person.

     Section 6.10. Credit Arrangements. As of the Closing Date, SCHEDULE 6.10 is
a complete and correct list of all credit agreements, indentures, purchase
agreements, Guaranties, Capital Leases and other investments, agreements and
arrangements presently in effect providing for or relating to extensions of
credit (including agreements and arrangements for the issuance of letters of
credit or for acceptance financing) in respect of which any LCC Consolidated
Entity is in any manner directly or contingently obligated; and the maximum
principal or face amounts of the credit in question, outstanding and which can
be outstanding, are correctly stated, and all Liens of any nature given or
agreed to be given as security therefor are correctly described or indicated in
such Schedule (except that Liens permitted under Section 8.03 are described as

     Section 6.11. Material Contracts. As of September 30, 1996, SCHEDULE 6.11
contains a complete and correct list of all revenue-producing contracts and all
Material Contracts between any LCC Consolidated Entity and another Person or

Material Contracts is in full force and effect with no default, anticipated or

                                       44

     Section 6.12. Proprietary Rights. As of the Closing Date, SCHEDULE 6.12
contains a complete and accurate list of (a) all patents, registered and
unregistered trademarks, registered service marks, and registered copyrights
owned or filed by any LCC Consolidated Entity (other than the Subsidiary

any LCC Consolidated Entity (other than the Subsidiary Borrower) with respect to
any Proprietary Rights used in the conduct of its business (excluding shrink

distributors in the ordinary course of business and except as set forth on
SCHEDULE 6.12, no LCC Consolidated Entity (other than the Subsidiary Borrower)
has granted licenses or other rights to any third party with respect to any
Proprietary Rights. Each of the LCC Consolidated Entities owns or has sufficient
right to use pursuant to a valid and enforceable license all Proprietary Rights
necessary for the conduct of its business without infringing the rights of
others except for such infringements as could not reasonably be expected to have
a Material Adverse Effect. No loss or expiration of any Proprietary Right, the
loss or expiration of which could reasonably be expected to have a Material
Adverse Effect, is pending or, to the knowledge of each Obligor, threatened.
Each of the LCC Consolidated Entities has taken reasonable and appropriate steps
to protect and preserve the confidentiality of its trade secrets and
confidential information as outlined on SCHEDULE 6.12. Except as set forth on
SCHEDULE 6.12, (i) no LCC Consolidated Entity has received notice from any
Person asserting the invalidity, misuse or unenforceability of any Proprietary
Rights owned or used by any LCC Consolidated Entity and to the best knowledge of
each Obligor, no such claims are threatened and there are no grounds for the
same, (ii) within the last five years, no LCC Consolidated Entity has received a
notice of nor is aware of any facts which in any LCC Consolidated Entity's
reasonable judgment indicate a reasonable likelihood of any conflict with the
asserted Proprietary Rights of others, (iii) to the best knowledge of each
Obligor, the conduct of each LCC Consolidated Entity's business has not
infringed or misappropriated and does not infringe or misappropriate any
Proprietary Rights of other Persons, nor would any future conduct as presently
proposed infringe any Proprietary Rights of other Persons, and the Proprietary
Rights owned by any LCC Consolidated Entity are not currently being infringed or
misappropriated by other Persons, except in each case for such infringements as
could not reasonably be expected to have a Material Adverse Effect.

     Section 6.13. Hazardous Materials. Each of the LCC Consolidated Entities is
in compliance with all Environmental Laws in effect in each jurisdiction where
it is presently doing business. No LCC Consolidated Entity is subject to any
liability under any Environmental Law.

any Governmental Authority by which any of its present or previously-owned or
leased real Properties has been designated, listed, or identified in any manner
by any Governmental Authority charged with administering or enforcing any
Environmental


                                       45

<PAGE>   51

Law as a Hazardous Material disposal or removal site, "Super Fund" clean-up
site, or candidate for removal or closure pursuant to any Environmental Law,
(ii) notice of any Lien arising under or in connection with any Environmental
Law that has attached to any revenues of, or to, any of its owned or leased real
Properties, or (iii) summons, citation, notice, directive, letter, or other
written or oral communication from any Governmental Authority concerning any
intentional or unintentional action or omission by such LCC Consolidated Entity
in connection with its ownership or leasing of any real Property resulting in
the releasing, spilling, leaking, pumping, pouring, emitting, emptying, dumping,
or otherwise disposing of any Hazardous Material into the environment resulting
in any violation of any Environmental Law.

     Section 6.14. No Default on Outstanding Judgments or Orders. As of the
Closing Date, each of the LCC Consolidated Entities has satisfied all judgments
and no LCC Consolidated Entity is in default with respect to any final judgment,
writ, injunction, decree, rule or regulation of any Governmental Authority.

     Section 6.15. No Defaults on Other Agreements. Except for the MCI Note
Purchase Documents, no LCC Consolidated Entity is a party to any indenture, loan
or credit agreement or any lease or other agreement or instrument or subject to
any corporate, partnership or limited liability company restriction which could
have a Material Adverse Effect. No LCC Consolidated Entity is in default in any
respect in the performance, observance or fulfillment of any of the obligations,
covenants or conditions contained in any agreement or instrument material to its
business to which it is a party.

     Section 6.16. Labor Disputes and Acts of God. Neither the Business nor the
Properties of any LCC Consolidated Entity are affected by any fire, explosion,
accident, strike, lockout or other labor dispute, drought, storm, hail,
earthquake, embargo, act of God or of the public enemy or other casualty
(whether or not covered by insurance), which could have a Material Adverse
Effect.

     Section 6.17. Governmental Regulation. Neither any LCC Consolidated Entity
nor any Affiliate is subject to regulation under the Public Utility Holding
Company Act of 1935, the Investment Company Act of 1940, the Interstate Commerce
Act, the Federal Power Act or any statute or regulation limiting its ability to
incur indebtedness for money borrowed as contemplated hereby.

     Section 6.18. No Forfeiture. Neither any LCC Consolidated Entity nor any
Affiliate is engaged in or proposes to be engaged in the conduct of any business
or activity which could result in a Forfeiture Proceeding and no Forfeiture
Proceeding against any of them is pending or threatened.

     Section 6.19. Solvency. The present fair saleable value of the assets of
each of the Borrower and the Subsidiary Borrower after giving effect to all the
transactions contemplated by the Facility Documents and the funding of the
Commitments and the


                                       46

<PAGE>   52

issuance of the Letters of Credit hereunder exceeds the amount that will be
required to be paid on or in respect of the existing Debts and other liabilities
(including contingent liabilities) of each of the Borrower and the Subsidiary
Borrower as they mature. The Property of each of the Borrower and the Subsidiary
Borrower does not constitute unreasonably small capital for each of the Borrower
and the Subsidiary Borrower to carry out its business as now conducted and as
proposed to be conducted including the capital needs of each of the Borrower and
the Subsidiary Borrower. Neither the Borrower nor the Subsidiary Borrower
intends to, nor does either the Borrower or the Subsidiary Borrower believe that
it will, incur Debts beyond its ability to pay such Debts as they mature (taking
into account the timing and amounts of cash to be received by each of the
Borrower and the Subsidiary Borrower, and of amounts to be payable on or in
respect of Debt of each of the Borrower and the Subsidiary Borrower). The cash
available to each of the Borrower and the Subsidiary Borrower, after taking into
account all other anticipated uses of the cash of each of the Borrower and the
Subsidiary Borrower, is anticipated to be sufficient to pay all such amounts on
or in respect of Debt of the Borrower when such amounts are required to be paid.
Neither the Borrower nor the Subsidiary Borrower believes that final judgments
against it in actions for money damages will be rendered at a time when, or in
an amount such that, either the Borrower or the Subsidiary Borrower will be

are hereby expressly waived by the Borrower and the Subsidiary Borrower and/or
(c) direct the Borrower to pay to the Administrative Agent an amount to be held
as cash security in the cash collateral account held by the Administrative Agent
under Section 3.08 equal to the Letter of Credit Obligations then outstanding;
provided that, in the case of an Event of Default referred to in Section

terminated, and the Notes, all interest thereon and all other amounts payable
under this Agreement shall be immediately due and payable without notice,

                      ARTICLE 11. UNCONDITIONAL GUARANTY.

     Section 11.01. Guarantied Obligations. Each of the Borrower (as to the
Swingline Notes) and the Subsidiary Guarantors (each of the foregoing entities
individually a "Guarantor" and collectively the "Guarantors"), jointly and
severally, in consideration of the execution and delivery of this Agreement by
the Lenders and the Administrative Agent, hereby irrevocably and unconditionally
guarantees to the Administrative Agent, for the benefit of the Lenders, as and
for such Guarantor's own debt, until final payment has been made:

          (a) the due and punctual payment in full in cash in the applicable
currency of the Obligations, in each case when and as the same shall become due
and payable, whether at maturity, pursuant to mandatory or optional prepayment,
by acceleration or otherwise, all in accordance with the terms and provisions of
this Agreement and the other Facility Documents, it being the intent of the
Guarantors that the guaranty set forth in this Section 11.01 (the "Unconditional
Guaranty") shall be a guaranty of payment and not a guaranty of collection; and


                                       64

<PAGE>   70

          (b) the punctual and faithful performance, keeping, observance, and
fulfillment by each Obligor of all duties, agreements, covenants and obligations
such Obligor contained in each of the Facility Documents to which it is a party.

     Section 11.02. Performance Under This Agreement. In the event any Obligor
fails to make, on or before the due date thereof, any payment of the principal
of, or interest on, the Notes, the Letter of Credit Obligations or the other
Obligations, or if any Obligor shall fail to perform, keep, observe, or fulfill
any other obligation referred to in clause (a) or clause (b) of Section 11.01
hereof in the manner provided in the Notes, the Letters of Credit or in any of
the other Facility Documents, and any such failure shall remain uncured at the
expiration of any applicable cure period provided herein or in the other
Facility Documents, the Guarantors shall cause forthwith to be paid the moneys,
or to be performed, kept, observed, or fulfilled each of such obligations, in
respect of which such failure has occurred.

     Section 11.03. Waivers. To the fullest extent permitted by law, each
Guarantor does hereby waive:

          (a) notice of acceptance of the Unconditional Guaranty;

          (b) notice of any borrowings under this Agreement, or the creation,
existence or acquisition of any of the Obligations, subject to such Guarantor's
right to make inquiry of the Administrative Agent to ascertain the amount of the
Obligations at any reasonable time;

          (c) notice of the amount of the Obligations, subject to each
Guarantor's right to make inquiry of the Administrative Agent to ascertain the
amount of the Obligations at any reasonable time;

          (d) notice of adverse change in the financial condition of the
Borrower, the Subsidiary Borrower, any other guarantor or any other fact that
might increase each Guarantor's risk hereunder;

          (e) notice of presentment for payment, demand, protest, and notice
thereof as to the Notes or any other Facility Document;

          (f) notice of any Default or Event of Default;

          (g) all other notices and demands to which each Guarantor might
otherwise be entitled (except if such notice or demand is specifically otherwise
required to be given to each Guarantor hereunder or under the other Facility
Documents);

          (h) the right by statute or otherwise to require any or each Lender or
the Administrative Agent to institute suit against the Borrower, the Subsidiary


                                       65

<PAGE>   71

Borrower or any other guarantor or to exhaust the rights and remedies of any or
each Lender or the Administrative Agent against the Borrower, the Subsidiary
Borrower or any other guarantor, each Guarantor being bound to the payment of
each and all Obligations, whether now existing or hereafter accruing, as fully
as if such Obligations were directly owing to each Lender by each Guarantor;

          (i) any defense arising by reason of any disability or other defense
(other than the defense that the Obligations shall have been fully and finally
performed and indefeasibly paid) of the Borrower or the Subsidiary Borrower or
by reason of the cessation from any cause whatsoever of the liability of the
Borrower or the Subsidiary Borrower in respect thereof; and

          (j) any stay (except in connection with a pending appeal), valuation,
appraisal, redemption or extension law now or at any time hereafter in force
which, but for this waiver, might be applicable to any sale of Property of each
Guarantor made under any judgment, order or decree based on this Agreement, and
each Guarantor covenants that it will not at any time insist upon or plead, or
in any manner claim or take the benefit or advantage of such law.

Until all of the Obligations shall have been paid in full, each of the
Guarantors hereby agrees to completely subordinate any right of subrogation,
reimbursement, or indemnity whatsoever in respect thereof and any right of
recourse to or with respect to any Property of the Borrower or the Subsidiary
Borrower. Nothing shall discharge or satisfy the obligations of any Guarantor
hereunder except the full and final performance and indefeasible payment in cash
in the applicable currency of the Obligations by such Guarantor, upon which each
Lender agrees to transfer and assign its interest in the Notes and the other
Facility Documents to such Guarantor without recourse, representation or
warranty of any kind (other than that such Lender owns its Notes and that such
Notes are free of Liens created by such Lender). All of the Obligations shall in
the manner and subject to the limitations provided herein for the acceleration
thereof forthwith become due and payable without notice.

     Section 11.04. Releases. Each of the Guarantors consents and agrees that,
without notice to or by such Guarantor and without affecting or impairing the
obligations of such Guarantor hereunder, each Lender or the Administrative
Agent, in the manner provided herein, by action or inaction, may:

          (a) compromise or settle, extend the period of duration or the time
for the payment, or discharge the performance of, or may refuse to, or otherwise
not, enforce, or may, by action or inaction, release all or any one or more
parties to, any one or more of the Notes or the other Facility Documents;

          (b) grant other indulgences to the Borrower or the Subsidiary Borrower
in respect thereof;


                                       66

<PAGE>   72

          (c) amend or modify in any manner and at any time (or from time to
time) any one or more of the Notes, the Letters of Credit and the other Facility
Documents in accordance with Section 13.01 or otherwise;

          (d) release or substitute any one or more of the endorsers or
guarantors of the Obligations whether parties hereto or not; and

          (e) exchange, enforce, waive, or release, by action or inaction, any
security for the Obligations (including, without limitation, any of the
collateral therefor) or any other guaranty of any of the Obligations.

     Section 11.05. Marshaling. Each of the Guarantors consents and agrees that:

          (a) neither the Administrative Agent nor any Lender shall be under no
obligation to marshal any assets in favor of each Guarantor or against or in
payment of any or all of the Obligations; and

          (b) to the extent the Borrower, the Subsidiary Borrower or any other
guarantor makes a payment or payments to any Lender, which payment or payments
or any part thereof are subsequently invalidated, declared to be fraudulent or
preferential, set aside, or required, for any of the foregoing reasons or for
any other reason, to be repaid or paid over to a custodian, trustee, receiver,
or any other party under any bankruptcy law, common law, or equitable cause,
then to the extent of such payment or repayment, the Obligations or part thereof
intended to be satisfied thereby shall be revived and continued in full force
and effect as if said payment or payments had not been made and such Guarantor
shall remain liable for such Obligation.

     Section 11.06. Liability. Each of the Guarantors agrees that the liability
of such Guarantor in respect of this Article 11 shall not be contingent upon the
exercise or enforcement by any Lender or the Administrative Agent of whatever
remedies such Lender or the Administrative Agent may have against the Borrower,
the Subsidiary Borrower or any other guarantor or the enforcement of any Lien or
realization upon any security such Lender or the Administrative Agent may at any
time possess.

     Section 11.07. Unconditional Obligation. The Unconditional Guaranty set
forth in this Article 11 is an absolute, unconditional, continuing and
irrevocable guaranty of payment and performance and shall remain in full force
and effect until the full and final payment of the Obligations without respect
to future changes in conditions, including change of law or any invalidity or
irregularity with respect to the issuance or assumption of any obligations
(including, without limitation, the Notes and the Letter of Credit Obligations)
of or by the Borrower, the Subsidiary Borrower or any other guarantor, or with
respect to the execution and delivery of any agreement (including, without
limitation, the Notes and the other Facility Documents) of the Borrower, the
Subsidiary Borrower or any other guarantor.

     Section 11.08. Election to Perform Obligations. Any election by any of the
Guarantors to pay or otherwise perform any of the obligations of any Obligor
under the Notes or under any of the other Facility Documents, whether pursuant
to this Article 11 or otherwise, shall not release such Obligor from any of its
other obligations under the Notes, the Letters of Credit or any of the other
Facility Documents.

     Section 11.09. No Election. The Administrative Agent shall have the right
to seek recourse against any one or more of the Guarantors to the fullest extent
provided for herein for such Guarantor's obligations under this Agreement
(including, without limitation, this Article 11) in respect of the Notes, the
Letters of Credit and the other Facility Documents. No election to proceed in
one form of action or proceeding, or against any party, or on any obligation,
shall constitute a waiver of the Administrative Agent's right to proceed in any
other form of action or proceeding or against other parties unless the
Administrative Agent has expressly waived such right in writing. Specifically,
but without limiting the generality of the foregoing, no action or proceeding by
any Lender or the Administrative Agent against any Obligor under any document or
instrument evidencing obligations of such Obligor to such Lender or the
Administrative Agent shall serve to diminish the liability of any of the
Guarantors under this Agreement (including, without limitation, this Article 11)
except to the extent that the Administrative Agent or such Lender finally and
unconditionally shall have realized payment by such action or proceeding,
notwithstanding the effect of any such action or proceeding upon such
Guarantor's right of subrogation against any Obligor.

     Section 11.10. Severability. Subject to applicable law, each of the rights
and remedies granted under this Article 11 to the Administrative Agent may be
exercised by the Administrative Agent without notice by the Administrative Agent
to, or the consent of or any other action by, any Lender, provided that the
Administrative Agent will promptly thereafter give each Lender notice of any
exercise of rights and remedies by the Administrative Agent under this Article
11.

     Section 11.11. Other Enforcement Rights. The Administrative Agent may
proceed, as provided in Article 11 hereof, to protect and enforce the
Unconditional Guaranty by suit or suits or proceedings in equity, at law or in
bankruptcy, and whether for the specific performance of any covenant or
agreement contained herein (including, without limitation, in this Article 11)
or in execution or aid of any power herein granted; or for the recovery of
judgment for the obligations hereby guarantied or for the enforcement of any
other proper, legal or equitable remedy available under applicable law. Each of
the Lenders shall have, to the fullest extent permitted by law and this
Agreement, a right of set-off against, any and all credits and any and all other
Property of any Guarantor, now or at any time whatsoever with, or in the
possession of, such Lender, or anyone acting for such Lender, as security for
any and all obligations of such Guarantor hereunder and such Lien shall be
deemed permitted for all purposes under Article 8 hereof.

     Section 11.12. Delay or Omission; No Waiver. No course of dealing on the
part of any Lender or the Administrative Agent and no delay or failure on the
part of any such Person to exercise any right hereunder (including, without
limitation, this Article 11) shall impair such right or operate as a waiver of
such right or otherwise prejudice such Person's rights, powers and remedies
hereunder. Every right and remedy given by the Unconditional Guaranty or by law
to any Lender or the Administrative Agent may be exercised from time to time as
often as may be deemed expedient by such Person.

     Section 11.13. Restoration of Rights and Remedies. If any Lender or the
Administrative Agent shall have instituted any proceeding to enforce any right
or remedy under the Unconditional Guaranty, under any Note held by such Lender,
or under any Security Document, and such proceeding shall have been discontinued
or abandoned for any reason, or shall have been determined adversely to such
Lender or the Administrative Agent, then and in every such case each such
Lender, the Administrative Agent, the Borrower, the Subsidiary Borrower and the
Guarantors shall, except as may be limited or affected by any determination in
such proceeding, be restored severally and respectively to its respective former
positions hereunder and thereunder, and thereafter, subject as aforesaid, the
rights and remedies of such Lender or the Administrative Agent shall continue as
though no such proceeding had been instituted.

     Section 11.14. Cumulative Remedies. No remedy under this Agreement
(including, without limitation, this Article 11), the Notes, the Letters of
Credit or any of the other Facility Documents is intended to be exclusive of any
other remedy, but each and every remedy shall be cumulative and in addition to
any and every other remedy given under this Agreement (including, without
limitation, this Article 11), the Notes, the Letters of Credit or any of the
other Facility Documents.

     Section 11.15. Survival. The obligations of the Guarantors under this
Article 11 shall survive the transfer and payment of any Obligation until the
indefeasible payment in full of all the Obligations and the expiration and
termination of the Letters of Credit and the Commitments.

     Section 11.16. No Setoff, Counterclaim or Withholding: Gross-Up. Each
payment by a Guarantor shall be made without setoff or counterclaim and without
withholding for or on account of any present or future taxes imposed by any
Governmental Authority. If any such withholding is so required, such Guarantor
shall make the withholding and pay the amount withheld to the appropriate
Governmental Authority before penalties attach thereto or interest accrues
thereon.

     Section 11.17. Payment in Applicable Currency. Any payment of a Guarantied
Obligation required to be made pursuant to this Agreement shall be made in the
currency in which such Guarantied Obligation is required to be made pursuant to
this Agreement, any Note or any other Facility Document.

                     ARTICLE 12. THE ADMINISTRATIVE AGENT.

     Section 12.01. Appointment, Powers and Immunities of Administrative Agent.
Each Lender hereby irrevocably (but subject to removal by the Required Lenders
pursuant to Section 12.09) appoints and authorizes the Administrative Agent to
act as its agent hereunder and under any other Facility Document with such
powers as are specifically delegated to the Administrative Agent by the terms of
this Agreement and any other Facility Document, together with such other powers
as are reasonably incidental thereto. The Administrative Agent shall have no
duties or responsibilities except those expressly set forth in this Agreement
and any other Facility Document, and shall not by reason of this Agreement be a
trustee for any Lender. The Administrative Agent shall not be responsible to the
Lenders for any recitals, statements, representations or warranties made by any
LCC Consolidated Entity or any of their respective officers and officials or by
any other Person contained in this Agreement or any other Facility Document, or
in any certificate or other document or instrument referred to or provided for
in, or received by any of them under, this Agreement or any other Facility
Document, or for the value, legality, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Facility Document
or any other document or instrument referred to or provided for herein or
therein, for the perfection or priority of any collateral security for the
Obligations or for any failure by any Obligor to perform any of their respective
obligations hereunder or thereunder. The Administrative Agent may employ agents
and attorneys-in-fact and shall not be responsible, except as to money or
securities received by it or its authorized agents, for the negligence or
misconduct of any such agents or attorneys-in-fact selected by it with
reasonable care. Neither the Administrative Agent nor any of its directors,
officers, employees or agents shall be liable or responsible to any Lender for
any action taken or omitted to be taken by it or them hereunder or under any
other Facility Document or in connection herewith or therewith, except for its
or their own gross negligence or willful misconduct.

     Section 12.02. Reliance by Administrative Agent. The Administrative Agent
shall be entitled to rely upon any certification, notice or other communication
(including any thereof by telephone, telex, telegram or cable) believed by it to
be genuine and correct and to have been signed or sent by or on behalf of the
proper Person or Persons, and upon advice and statements of legal counsel,
independent accountants and other experts selected by the Administrative Agent.
The Administrative Agent may deem and treat each Lender as the holder of the
Obligations attributable to it for all purposes hereof unless and until a notice
of the assignment or transfer thereof satisfactory to the Administrative Agent
signed by such Lender shall have been furnished to the Administrative Agent but
the Administrative Agent shall not be required to deal with any Person who has
acquired a participation in any Obligation from a Lender. As to any matters not
expressly provided for by this Agreement or any other Facility Document, the
Administrative Agent shall in all cases be fully protected in acting, or in
refraining from acting, hereunder in accordance with instructions signed by the
Required Lenders, and such


                                       70

<PAGE>   76

instructions of the Required Lenders and any action taken or failure to act
pursuant thereto shall be binding on all of the Lenders and any other holder of
all or any portion of any Obligation.

     Section 12.03. Defaults. The Administrative Agent shall not be deemed to
have knowledge of the occurrence of a Default or Event of Default (other than
the non-payment of principal of or interest on the Loans and the Letter of
Credit Obligations to the extent the same is required to be paid to the
Administrative Agent for the account of the Lenders) unless the Administrative
Agent has received notice from a Lender or the Borrower specifying such Default
or Event of Default and stating that such notice is a "Notice of Default." In
the event that the Administrative Agent receives such a notice of the occurrence
of a Default or Event of Default, the Administrative Agent shall give prompt
notice thereof to the Lenders (and shall give each Lender prompt notice of each
such non-payment). The Administrative Agent shall (subject to Section 12.08)
take such action with respect to such Default or Event of Default which is
continuing as shall be directed by the Required Lenders; provided that, unless
and until the Administrative Agent shall have received such directions, the
Administrative Agent may take such action, or refrain from taking such action,
with respect to such Default or Event of Default as it shall deem advisable in
the best interest of the Lenders; and provided further that the Administrative
Agent shall not be required to take any such action which it determines to be
contrary to law.

     Section 12.04. Rights of Administrative Agent as a Lender. With respect to
its Commitments and the Obligations held by it, The Chase Manhattan Bank in its
capacity as a Lender hereunder shall have the same rights and powers hereunder
as any other Lender and may exercise the same as though it were not acting as
the Administrative Agent, and the term "Lender" or "Lenders" shall, unless the
context otherwise indicates, include The Chase Manhattan Bank in its capacity as
a Lender. The Chase Manhattan Bank and its affiliates may (without having to
account therefor to any Lender) accept deposits from, lend money to (on a
secured or unsecured basis), and generally engage in any kind of banking, trust
or other business with, any LCC Consolidated Entity (and any of its their
respective affiliates) as if it were not acting as the Administrative Agent, and
The Chase Manhattan Bank may accept fees and other consideration from any LCC
Consolidated Entity and any of their respective affiliates for services in
connection with this Agreement or otherwise without having to account for the
same to the Lenders. Although The Chase Manhattan Bank and its affiliates may in
the course of such relationships and relationships with other Persons acquire
information about any LCC Consolidated Entity, their respective affiliates and
such other Persons, the Administrative Agent shall have no duty to disclose such
information to the Lenders.

     Section 12.05. Indemnification of Administrative Agent. The Lenders agree
to indemnify the Administrative Agent (to the extent not reimbursed under
Section 13.03 or under the applicable provisions of any other Facility Document,
but without


                                       71

<PAGE>   77

limiting the obligations of any Obligor under Section 13.03 or such provisions),
ratably in accordance with the aggregate unpaid principal amount of the
Obligations attributable to the Lenders (without giving effect to any
participations, in all or any portion of the Obligations, sold by them to any
other Person) (or, if no Obligations are at the time outstanding, ratably in
accordance with their respective Commitments), for any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind and nature whatsoever which may be imposed
on, incurred by or asserted against the Administrative Agent in any way relating
to or arising out of this Agreement, any other Facility Document or any other
documents contemplated by or referred to herein or the transactions contemplated
hereby or thereby (including, without limitation, the costs and expenses which
the Obligors are obligated to pay under Section 13.03 or under the applicable
provisions of any other Facility Document but excluding, unless a Default or
Event of Default has occurred, normal administrative costs and expenses incident
to the performance of its agency duties hereunder) or the enforcement of any of
the terms hereof or thereof or of any such other documents or instruments;
provided that no Lender shall be liable for any of the foregoing to the extent
they arise from the gross negligence or wilful misconduct of the party to be
indemnified.

     Section 12.06. Documents. The Administrative Agent will forward to each
Lender, promptly after the Administrative Agent's receipt thereof, a copy of
each report, notice or other document required by this Agreement or any other
Facility Document to be delivered to the Administrative Agent for such Lender.

     Section 12.07. Non-Reliance on Administrative Agent and Other Lenders. Each
Lender agrees that it has, independently and without reliance on the
Administrative Agent or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own credit analysis of the
LCC Consolidated Entities and decision to enter into this Agreement and that it
will, independently and without reliance upon the 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 analysis and decisions in
taking or not taking action under this Agreement or any other Facility Document.
The Administrative Agent shall not be required to keep itself informed as to the
performance or observance by the Obligors of this Agreement or any other
Facility Document or any other document referred to or provided for herein or
therein or to inspect the Properties or books of any LCC Consolidated Entity.
Except for notices, reports and other documents and information expressly
required to be furnished to the Lenders by the Administrative Agent hereunder,
the Administrative Agent shall not have any duty or responsibility to provide
any Lender with any credit or other information concerning the affairs,
financial condition or business of any LCC Consolidated Entity (or any of their
respective affiliates) which may come into the possession of the Administrative
Agent or any of its affiliates. The Administrative Agent shall not be required
to file this Agreement, any other Facility Document or any document or
instrument referred to herein or therein, for record or give notice of this
Agreement,


                                       72

<PAGE>   78

any other Facility Document or any document or instrument referred to herein or
therein, to anyone.

     Section 12.08. Failure of Administrative Agent to Act. Except for action
expressly required of the Administrative Agent hereunder, the Administrative
Agent shall in all cases be fully justified in failing or refusing to act
hereunder unless it shall have received further assurances (which may include
cash collateral) of the indemnification obligations of the Lenders under Section
12.05 in respect of any and all liability and expense which may be incurred by
it by reason of taking or continuing to take any such action.

     Section 12.09. Resignation or Removal of Administrative Agent. Subject to
the appointment and acceptance of a successor Administrative Agent as provided
below, the Administrative Agent may resign at any time by giving written notice
thereof to the Lenders and the Borrower, and the Administrative Agent may be
removed at any time with or without cause by the Required Lenders; provided that
the Borrower and the other Lenders shall be promptly notified thereof. Upon any
such resignation or removal, the Required Lenders shall have the right to
appoint a successor Administrative Agent. If no successor Administrative Agent
shall have been so appointed by the Required Lenders and shall have accepted
such appointment within 30 days after the retiring Administrative Agent's giving
of notice of resignation or the Required Lenders' removal of the retiring
Administrative Agent, then the retiring Administrative Agent may, on behalf of
the Lenders, appoint a successor Administrative Agent, which shall be a bank
which has an office in New York, New York. The Required Lenders or the retiring
Administrative Agent, as the case may be, shall upon the appointment of a
successor Administrative Agent promptly so notify the Borrower and the other
Lenders. Upon the acceptance of any appointment as Administrative Agent
hereunder by a successor Administrative Agent, such successor Administrative
Agent shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Administrative Agent, and the retiring
Administrative Agent shall be discharged from its duties and obligations
hereunder. After any retiring Administrative Agent's resignation or removal
hereunder as Administrative Agent, the provisions of this Article 12 shall
continue in effect for its benefit in respect of any actions taken or omitted to
be taken by it while it was acting as the Administrative Agent.

     Section 12.10. Amendments Concerning Agency Function. The Administrative
Agent shall not be bound by any waiver, amendment, supplement or modification of
this Agreement or any other Facility Document which affects its duties hereunder
or thereunder unless it shall have given its prior consent thereto.

     Section 12.11. Liability of Administrative Agent. The Administrative Agent
shall not have any liabilities or responsibilities to any Obligor on account of
the failure of any Lender to perform its obligations hereunder or to any Lender
on account of the


                                       73

<PAGE>   79

failure of any Obligor or any other Lender to perform its obligations hereunder
or under any other Facility Document.

     Section 12.12. Transfer of Agency Function. Without the consent of the
Obligors or any Lender, the Administrative Agent may at any time or from time to
time transfer its functions as Administrative Agent hereunder to any of its
offices wherever located, provided that the Administrative Agent shall promptly
notify the Borrower and the Lenders thereof.

     Section 12.13. Non-Receipt of Funds by the Administrative Agent. Unless the
Administrative Agent shall have been notified by a Lender or the Borrower
(either one as appropriate being the "Payor") prior to the date on which such
Lender is to make payment hereunder to the Administrative Agent of the proceeds
of a Loan or the Borrower or the Subsidiary Borrower is to make payment to the
Administrative Agent, as the case may be (either such payment being a "Required
Payment"), which notice shall be effective upon receipt, that the Payor does not
intend to make the Required Payment to the Administrative Agent, the
Administrative Agent may assume that the Required Payment has been made and may,
in reliance upon such assumption (but shall not be required to), make the amount
thereof available to the intended recipient on such date and, if the Payor has
not in fact made the Required Payment to the Administrative Agent, the recipient
of such payment (and, if such recipient is the Borrower or the Subsidiary
Borrower and the Payor Lender fails to pay the amount thereof to the
Administrative Agent forthwith upon demand, the Borrower or the Subsidiary
Borrower) shall, on demand, repay to the Administrative Agent the amount made
available to it together with interest thereon for the period from the date such
amount was so made available by the Administrative Agent until the date the
Administrative Agent recovers such amount at a rate per annum equal to the
average daily Federal Funds Rate for such period.

     Section 12.14. Withholding Taxes. Each Lender represents that it is
entitled to receive any payments to be made to it hereunder without the
withholding of any tax and will furnish to the Administrative Agent such forms,
certifications, statements and other documents as the Administrative Agent may
request from time to time to evidence such Lender's exemption from the
withholding of any tax imposed by any jurisdiction or to enable the
Administrative Agent to comply with any applicable laws or regulations relating
thereto. Without limiting the effect of the foregoing, if any Lender is not
created or organized under the laws of the United States of America or any state
thereof, in the event that the payment of interest by the Borrower or the
Subsidiary Borrower is treated for U.S. income tax purposes as derived in whole
or in part from sources from within the U.S., such Lender will furnish to the
Administrative Agent Form 4224 or Form 1001 of the Internal Revenue Service, or
such other forms, certifications, statements or documents, duly executed and
completed by such Lender as evidence of such Lender's exemption from the
withholding of U.S. tax with respect thereto. The Administrative Agent shall not
be obligated to make any payments hereunder to such Lender in respect of any


                                       74

<PAGE>   80

Obligation until such Lender shall have furnished to the Administrative Agent
the requested form, certification, statement or document.

     Section 12.15. Several Obligations and Rights of Lenders. The failure of
any Lender to make any Loan to be made by it on the date specified therefor
shall not relieve any other Lender of its obligation to make its Loans on such
date, but no Lender shall be responsible for the failure of any other Lender to
make a Loan to be made by such other Lender. The amounts payable at any time
hereunder to each Lender shall be a separate and independent debt, and each
Lender shall be entitled to protect and enforce its rights arising out of this
Agreement, and it shall not be necessary for any other Lender to be joined as an
additional party in any proceeding for such purpose.

     Section 12.16. Pro Rata Treatment of Loans, Etc. Except to the extent
otherwise provided: (a) each borrowing under Section 2.01 shall be made from the
Lenders, each reduction or termination of the amount of the Commitments under
Section 2.08 shall be applied to the Commitments of the Lenders, and each
payment of commitment fee accruing under Section 2.12(a) shall be made for the
account of the Lenders, pro rata according to the amounts of their respective
unused Commitments; (b) each conversion under Section 2.05 of Loans of a
particular type (but not conversions provided for by Section 4.04), shall be
made pro rata among the Lenders holding Loans of such type according to the
respective principal amounts of such Loans by such Lenders; (c) each prepayment
and payment of principal of or interest on Loans of a particular type, a
particular class and a particular Interest Period shall be made to the
Administrative Agent for the account of the Lenders holding Loans of such type,
class and Interest Period pro rata in accordance with the respective unpaid
principal amounts of such Loans of such type, class and Interest Period held by
such Lenders; and (d) each prepayment and payment of fees under Section 3.09(a)
and Letter of Credit Obligations shall be made pro rata in accordance with the
pro rata share of the Lenders in the Letter of Credit Obligations held by each
of them.

     Section 12.17. Sharing of Payments Among Lenders. If a Lender shall obtain
payment of any principal of or interest on any Obligation held by it through the
exercise of any right of setoff, banker's lien, counterclaim, or by any other
means, it shall promptly purchase from the other Lenders participations in (or,
if and to the extent specified by such Lender, direct interests in) the
Obligations of the other Lenders in such amounts, and make such other
adjustments from time to time as shall be equitable to the end that all the
Lenders shall share the benefit of such payment (net of any expenses which may
be incurred by such Lender in obtaining or preserving such benefit) pro rata in
accordance with the unpaid principal and interest on the Obligations held by
each of them. To such end the Lenders shall make appropriate adjustments among
themselves (by the resale of participations sold or otherwise) if such payment
is rescinded or must otherwise be restored. Each of the Obligors agrees that any
Lender so purchasing a participation (or direct interest) in the


                                       75

<PAGE>   81

Obligations held by the other Lenders may exercise all rights of setoff,
banker's lien, counterclaim or similar rights with respect to such participation
(or direct interest). Nothing contained herein shall require any Lender to
exercise any such right or shall affect the right of any Lender to exercise, and
retain the benefits of exercising, any such right with respect to any other
indebtedness of any Obligor or its affiliates.

     Section 12.18. Security Documents. Subject to the foregoing provisions of
this Section 12, the Administrative Agent shall, on behalf of the Lenders: (a)
execute any and all of the Security Documents on behalf of the Lenders; (b) hold
and apply any and all Collateral, and the proceeds thereof, at any time received
by it, in accordance with the provisions of the Security Documents and this
Agreement; (c) exercise any and all rights, powers and remedies of the Lenders
under this Agreement or any of the Security Documents, including the giving of
any consent or waiver or the entering into of any amendment, subject to the
provisions of Section 12.03; (d) execute, deliver and file financing statements,
mortgages, deeds of trust, lease assignments and other such agreements, and
possess instruments on behalf of any or all of the Lenders; and (e) in the event
of acceleration of the Borrower's or the Subsidiary Borrower's obligations
hereunder, use its best efforts to sell or otherwise liquidate or dispose of the
Collateral and otherwise exercise the rights of the Lenders thereunder upon the
direction of the Required Lenders.

     Section 12.19. Collateral. Notwithstanding Section 12.18, the
Administrative Agent and the other Lenders agree, as among themselves, that the
Administrative Agent shall not, without the consent of the Required Lenders,
make any sale or disposition of the Collateral pursuant to any of the Security
Documents. The Administrative Agent acknowledges to the other Lenders that it is
acting in an agency capacity hereunder and that the security interest in the
Collateral granted under the Security Documents secures the Obligations held by
all of the Lenders. In the event of any Default or Event of Default, the
Administrative Agent will apply and/or pay over to the Lenders any net proceeds
derived from the Collateral pro rata on the basis of the aggregate unpaid
principal and interest of the Obligations held by the Lenders. The
Administrative Agent will be reimbursed or properly indemnified by the Lenders
in the event the Administrative Agent is requested by the Lenders to take or
omit to take any action with respect to the Collateral (any such reimbursement
or indemnification to be pro rata as provided in Section 12.05). The
Administrative Agent shall have the right to retain counsel to advise it as to
any action or decision with respect to the Collateral and shall be reimbursed by
the other Lenders for the cost of the same (to the extent the Administrative
Agent is not reimbursed by any Obligor) prior to distributing any of the
Collateral or any proceeds thereof (any such reimbursement to be pro rata as
aforesaid).

     Section 12.20. Amendment of Article 12. Each of the Obligors hereby agrees
that the foregoing provisions of this Article 12 constitute an agreement amount
the Administrative Agent and the Lenders and that any and all of the provisions
of this


                                       76

<PAGE>   82

Article 12 may be amended at any time by the Administrative Agent and the
Required Lenders without the consent or approval of, or notice to, such Obligor.


                           ARTICLE 13. MISCELLANEOUS.

     Section 13.01. Amendments and Waivers. Except as otherwise expressly
provided in this Agreement, any provision of this Agreement may be amended or
modified only by an instrument in writing signed by the Borrower, the Subsidiary
Borrower (if affected), the Administrative Agent and the Required Lenders, or by
the Borrower and the Administrative Agent acting with the consent of the
Required Lenders and any provision of this Agreement may be waived by the
Required Lenders or by the Administrative Agent acting with the consent of the
Required Lenders; provided that no amendment, modification or waiver shall,
unless by an instrument signed by all of the Lenders or by the Administrative
Agent acting with the consent of all of the Lenders: (a) increase or extend the
term, or extend the time or waive any requirement for the reduction or
termination, of the Commitments; (b) extend the date fixed for the payment of
principal of or interest on any Loan, any Letter of Credit Obligation or any fee
payable hereunder; (c) reduce the amount of any payment of principal thereof or
the rate at which interest is payable thereon or any fee payable hereunder, (d)
alter the terms of this Section 12.01; (e) amend the definition of the term
"Required Lenders"; (f) waive any of the conditions precedent set forth in
Article 5 hereof; (g) discharge any Guarantor from the Unconditional Guaranty
under Article 11 hereof; or (h) release all or any part of the Collateral in
excess of $500,000 and provided, further, that any amendment of Article 12 or
any amendment which increases the obligations of the Administrative Agent
hereunder shall require the consent of the Administrative Agent. No failure on
the part of the Administrative Agent or any Lender to exercise, and no delay in
exercising, any right hereunder shall operate as a waiver thereof or preclude
any other or further exercise thereof or the exercise of any other right. The
remedies herein provided are cumulative and not exclusive of any remedies
provided by law.

     Section 13.02. Usury. Anything herein to the contrary notwithstanding, the
obligations of the Obligors under this Agreement, the Notes and the other
Facility Documents shall be subject to the limitation that payments of interest
shall not be required to the extent that receipt thereof would be contrary to
provisions of law applicable to a Lender limiting rates of interest which may be
charged or collected by such Lender.

     Section 13.03. Expenses. Each of the Obligors (including, insofar as it is
responsible for such expenses, the Subsidiary Borrower) shall reimburse the
Administrative Agent on demand for all reasonable costs, expenses and charges
(including, without limitation, reasonable fees and charges of external legal
counsel for the Administrative Agent) in connection with the preparation of, and
any amendment, supplement, waiver or modification to (in each case, whether or
not consummated), this Agreement, any other Facility Document and any other


                                       77

<PAGE>   83

documents prepared in connection herewith or therewith. Each of the Obligors
shall reimburse the Administrative Agent and each Lender for all reasonable
costs, expenses and charges (including, without limitation, reasonable fees and
charges of external legal counsel for the Administrative Agent and each Lender)
in connection with the enforcement or preservation of any rights or remedies
during the existence of a Default or Event of Default (including, without
limitation, in connection with any restructuring or insolvency or bankruptcy
proceeding). Each of the Obligors agrees to indemnify the Administrative Agent
and each Lender and their respective directors, officers, employees and agents
from, and hold each of them harmless against, any and all losses, liabilities,
claims, damages or expenses incurred by any of them arising out of or by reason
of any investigation or litigation or other proceedings (including any
threatened investigation or litigation or other proceedings) arising out of or
relating to this Agreement or any other Facility Document or to any actual or
proposed use by the Borrower of the proceeds of the Loans or the Letters of
Credit or to the performance or enforcement of this Agreement or the other
Facility Documents, including, without limitation, the reasonable fees and
disbursements of counsel incurred in connection with any such investigation or
litigation or other proceedings (but excluding any such losses, liabilities,
claims, damages or expenses incurred by reason of the gross negligence or wilful
misconduct of the Person to be indemnified).

     Section 13.04. Survival. The obligations of the Obligors under Sections
4.01, 4.05, 13.03 and 13.18 shall survive the repayment of the Obligations and
the termination of the Commitments and the Letters of Credit.

     Section 13.05. Assignment; Participations.

          (a) This Agreement shall be binding upon, and shall inure to the
benefit of, the Borrower, the Subsidiary Borrower, the Guarantors, the
Administrative Agent, the Lenders and their respective successors and assigns,
except that the Borrower, the Subsidiary Borrower and the Subsidiary Guarantors
may not assign or transfer its rights or obligations hereunder except as
otherwise permitted under Section 8.10(c). Each Lender may assign or sell
participations in all of its rights and obligations hereunder or any part of its
rights and obligations hereunder to another financial institution or other
entity; provided that any assignment or participation by any Lender of its
rights and obligations in respect of the Letters of Credit shall require the
prior consent of the Issuing Lender, such consent not to be unreasonably
withheld, in which event (i) in the case of an assignment, upon notice thereof
by the Lender to the Borrower or Subsidiary Borrower with a copy to the
Administrative Agent, the assignee shall have, to the extent of such assignment
(unless otherwise provided therein), the same rights, benefits and obligations
as it would have if it were a Lender hereunder; and (ii) in the case of a

and all amounts payable by the Borrower and the Subsidiary Borrower under
Article 4 shall be determined as if such Lender had not sold such participation.

take or omit to take any action hereunder except action directly relating to (i)
the extension of a payment date with respect to any portion of the principal of

shall require any such prospective assignee or such participant (prospective or
otherwise) to agree in writing to maintain the confidentiality of such
information. In connection with any assignment or sale of a participation
interest pursuant to this paragraph (a), the assigning or selling Lender shall
pay the Administrative Agent an administrative fee for processing such
assignment or participation in the amount of $5,000.

          (b) In addition to the assignments and participations permitted under
paragraph (a) above, any Lender may assign and pledge all or any portion of the
Obligations held by it to (i) any affiliate of such Lender or (ii) any Federal
Reserve Bank as collateral security pursuant to Regulation A of the Board of
Governors of the Federal Reserve System and any Operating Circular issued by
such Federal Reserve Bank. No such assignment shall release the assigning Lender
from its obligations hereunder.

limitation of) any right of setoff, banker's lien or counterclaim a Lender may
otherwise have, each Lender shall be entitled, at its option, to offset balances

account of such Obligor at any of such Lender's offices, in Dollars, in
Norwegian Krone or in any other currency, against any amount payable by such
Obligor to such Lender under this Agreement, such Lender's Notes, any Letter of
Credit or any other Facility Document which is not paid when due (regardless of
whether such balances are then due to


                                       79

such Obligor), in which case it shall promptly notify the Borrower and the
Administrative Agent thereof; provided that such Lender's failure to give such
notice shall not affect the validity thereof. Payments by any Obligor hereunder
shall be made without setoff or counterclaim.

immunity from jurisdiction of any court or from any legal process (whether from
service or notice, attachment prior to judgment, attachment in aid of execution,
execution or otherwise) with respect to itself or its Property, such Obligor
hereby irrevocably waives such immunity in respect of its obligations under this
Agreement, the Notes, the Letters of Credit and the other Facility Documents.

headings and captions hereunder are for convenience only and shall not affect

to be severable. If for any reason any provision of this Agreement shall be held
invalid or unenforceable in whole or in part in any jurisdiction, such provision
shall, as to such jurisdiction, be ineffective to the extent of such invalidity
or unenforceability without in any manner affecting the validity or
enforceability thereof in any other jurisdiction or the remaining provisions
hereof in any jurisdiction. Without limiting the foregoing, to the extent that
mandatory and non-waivable provisions of applicable law (including but not
limited to any applicable business corporation and partnership laws) otherwise
would render the full amount of any Guarantor's obligations under this Agreement
and under the other Facility Documents invalid or unenforceable, the respective
obligations of such Guarantor under this Agreement and under the other Facility

INTERPRETED AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

OR RULES ARE DESIGNATED, THE UCP AND AS TO MATTERS NOT GOVERNED BY THE UCP, THE
LAWS OF THE STATE OF NEW YORK.

     Section 13.14. Confidentiality. Each Lender and the Administrative Agent
agrees (on behalf of itself and each of its affiliates, directors, officers,
employees and


                                       81

representatives) to use reasonable precautions to keep confidential, in
accordance with safe and sound banking practices, any non-public information
supplied to it by the Borrower pursuant to this Agreement which is identified by
the Borrower as being confidential at the time the same is delivered to such
Lender or the Administrative Agent, provided that nothing herein shall limit the
disclosure of any such information (i) to the extent required by applicable
statute, rule, regulation or judicial process, (ii) to counsel for any of the
Lenders or the Administrative Agent, (iii) to bank examiners, auditors or
accountants, (iv) in connection with any litigation to which any one or more of
the Lenders is a party or (v) to any assignee or participant (or prospective
assignee or participant) so long as such assignee or participant (or prospective
assignee or participant) agrees in writing to use reasonable precautions to keep
such information confidential; and provided finally that in no event shall any
Lender or the Administrative Agent be obligated or required to return any
materials furnished by the Borrower. The obligations of the Lenders and the
Administrative Agent under this Section 13.14 shall survive the repayment of the
Obligations and the termination of the Commitments and the Letters of Credit.

     Section 13.15. Treatment of Certain Information. Each of the Obligors (a)
acknowledges that services may be offered or provided to it (in connection with
this Agreement or otherwise) by each Lender or by one or more of their
respective subsidiaries or affiliates and (b) acknowledges that information

provided to each such subsidiary and affiliate.

     Section 13.16. Reaffirmation. Each of the Obligors acknowledges that the
Liens granted to the Administrative Agent under the Security Documents in the
Collateral secure all Obligations of each of the Obligors under this Agreement,
the Notes, the Letters of Credit and the other Facility Documents, including,
without limitation, all liabilities and obligations under the Loans as herein
modified and increased and all of the Letter of Credit Obligations. Each of the
Obligors hereby expressly grants, bargains, conveys, assigns, transfers,
mortgages, hypothecates, pledges and grants a continuing security interest to
the Administrative Agent in all right, title and interest of such Obligor in and
to the "Collateral" as defined in each of the Security Agreement, the
Intellectual Property Security Agreement and the Pledge Agreement. All
references to "Note" or "Notes" in any Facility Document shall be deemed to be
to the Notes issued hereunder. All references to "Loan" or "Loans" in any
Facility Document shall be deemed to be to the Loans incurred hereunder. All
references to "Commitment" or "Commitments" in any Facility shall be deemed to
be to the Commitments granted hereunder. All references to "Secured Obligations"
in any Facility Document shall be deemed to include all liabilities and
obligations under the Loans as herein modified and increased and all of the
Letter of Credit Obligations. Each of the Obligors further acknowledges and

     Section 13.17. Revised Schedules. Each of the Administrative Agent, the
Lenders and the Obligors hereby agrees that (a) Schedule A to the Security
Agreement is hereby amended and restated as set forth on SCHEDULE A hereto, (b)
Schedule A to the Intellectual Property Security Agreement is hereby amended and
restated as set forth on SCHEDULE B hereto and (c) Schedule A to the Pledge
Agreement is hereby amended and restated as set forth on SCHEDULE C hereto.

     Section 13.19. Refund of Taxes. The obligations of each Obligor under this
Agreement, the Notes, the Letters of Credit and the other Facility Documents to
make payments in Dollars or in Norwegian Krone (the "Obligation Currency") shall
not be discharged or satisfied by any tender or recovery pursuant to any
judgment expressed in or converted into any currency other than the Obligation
Currency, except to the extent that such tender or recovery results in the
effective receipt by the Administrative Agent or a Lender of the full amount of
the Obligation Currency expressed to be payable to them under this Agreement,
the Notes, the Letters of Credit and the other Facility Documents. If for the
purpose of obtaining or enforcing judgment against any Obligor in any court or
in any jurisdiction, it becomes necessary to convert into or from any currency
other than the Obligation Currency (such other currency being hereinafter
referred to as the "Judgment Currency") an amount due in the Obligation
Currency, the conversion shall be made, at the Norwegian Krone Equivalent or
Dollar Equivalent, in the case of Norwegian Krone or Dollars, and, in the case
of other currencies, the rate of exchange (as quoted by the Administrative Agent
or if the Administrative Agent does not quote a rate of exchange on such
currency, by a known dealer in such currency designated by the Administrative
Agent) determined, in each case, as on the day immediately preceding the day on
which the judgment is given (such Banking Day being hereinafter referred to as
the "Judgment Currency Conversion Date").

          (b) If there is a change in the rate of exchange prevailing between
the Judgment Currency Conversion Date and the date of actual payment of the
amount due, each Obligor covenants and agrees to pay such additional amounts, if
any, as may be necessary to ensure that the amount paid in the Judgment
Currency, when converted at the rate of exchange prevailing on the date of
payment, will produce the amount of the Obligation Currency which could have
been purchased with the amount of Judgment Currency stipulated in the judgment
or judicial award at the rate of exchange prevailing on the Judgment Currency
Conversion Date.

          (c) For purposes of determining the Norwegian Krone Equivalent or
Dollar Equivalent or rate of exchange for this Section 13.18, such amount shall
include any premium and costs payable in connection with the purchase of the
Obligation Currency.

     Section 13.18. Judgment Currency. If a Lender shall become aware that it is
eligible for a refund in respect of Taxes actually paid by the Borrower or the
Subsidiary Borrower pursuant to Section 4.06, it shall promptly notify the
Borrower


                                       83

<PAGE>   89

or the Subsidiary Borrower, as applicable, of the availability of such refund
and shall, within 30 days after receipt of a request by the Borrower or the
Subsidiary Borrower, as applicable, apply for such refund or shall furnish to
the Borrower or the Subsidiary Borrower, as applicable, such forms, duly
completed, as will enable the Borrower or the Subsidiary Borrower, as
applicable, to claim such refund on its own behalf. If any Lender receives a
refund in respect of any Taxes paid by the Borrower or the Subsidiary Borrower,
as applicable, pursuant to Section 4.06, it shall repay such refund within 30
days after receipt, to the Borrower or the Subsidiary Borrower, as applicable,
net of all reasonable out-of-pocket expenses of such Lender and without
interest; provided that the Borrower or the Subsidiary Borrower, as applicable,
agrees to return to such Lender the amount paid by it to the applicable Lender
with respect to such refund (plus applicable penalties, interest or other
charges) in the event such Lender is required to repay such refund.

The Chase Manhattan Bank,
 as Administrative Agent
4 Chase Metrotech Center
Brooklyn, New York  11245

Each of the Lenders signatory to the
 Credit Agreement referred to below

Ladies and Gentlemen:

I have acted as counsel to LCC International, Inc., a corporation organized
under the laws of Delaware (the "Borrower"), and its Subsidiaries, in connection
with the execution and delivery of that certain Second Amended and Restated
Credit Agreement dated as of December 15, 1997 (the "Credit Agreement") among
the Borrower, European Technology Partner AS, LCC Design Services, L.L.C., LCC
Development Company, L.L.C., Microcell Management, Inc., each of the lenders
signatory thereto and The Chase Manhattan Bank, as Administrative Agent. Except
as otherwise defined herein, all terms used herein and defined in the Credit
Agreement shall have the meanings assigned to them therein.

In connection with this opinion, I have examined executed copies of the Facility
Documents and such other documents, records, agreements and certificates as I
have deemed appropriate. I have also reviewed such matters of law as I have
considered relevant for the purpose of this opinion.

Based upon the foregoing, I am of the opinion that:

         1)       Each of the LCC Consolidated Entities is a corporation,
                  partnership or limited liability company duly organized,
                  validly existing and in good standing under the laws of the
                  jurisdiction of its organization, has the corporate,
                  partnership or limited liability company power and authority
                  to own its assets and to transact the business in which it is
                  now engaged or proposed to be engaged and is duly qualified as
                  a foreign corporation, partnership or limited liability
                  company and is in good standing under the laws of each other
                  jurisdiction in which such qualification is required and in
                  which the failure to so quality or be in good standing could
                  reasonably be expected to have a Material Adverse Effect.

         2)       Each of the Facility Documents to which it is a party has been
                  duly executed and delivered by such Obligor. The execution,
                  delivery and performance by each of the Obligors of the
                  Facility Documents to which it is a party have been duly
                  authorized by all necessary corporate, partnership and limited
                  liability company action and do not and will not: (a) require
                  any consent or approval of its members which has not been
                  obtained; (b) contravene its organizational documents; (c)
                  violate any provision of, or require any filing (other than
                  the filings required pursuant to the terms of the Security
                  Documents), registration, consent or approval under, any law,
                  rule, regulation (including, without limitation, Regulation
                  U), order, writ, judgment, injunction, decree, determination
                  or award presently in effect having applicability to the
                  Parent or any of its Subsidiaries; (d) result in breach of
                  or constitute a default or require any consent under

<PAGE>   105
                  any indenture or loan or credit agreement, or any other
                  agreement, lease or instrument to which the Parent or any of
                  its Subsidiaries is a party or by which their respective
                  Properties may be bound or affected; (e) result in, or
                  require, the creation or imposition of any Lien (other than as
                  created under the Security Documents), upon or with respect to
                  any of the Properties now owned or hereafter acquired by the
                  Parent or any of its Subsidiaries; or (f) cause the Parent or
                  any of its Subsidiaries to be in default under any such law,
                  rule, regulation, order, writ, judgment, injunction, decree,
                  determination or award of any such indenture, agreement, lease
                  or instrument.

         3)       Each Facility Document to which any Obligor is a party is a
                  legal, valid and binding obligation of such Obligor
                  enforceable against such Obligor in accordance with its terms,
                  except to the extent that such enforcement may be limited by
                  applicable bankruptcy, insolvency and other similar laws
                  affecting creditors' rights generally and general principles
                  of equity (regardless of whether such enforceability is
                  considered in a proceeding at law or in equity).

If you have any questions, please call me.

Sincerely,

/s/  Peter A. Deliso

Our ref.:  TPD/hco                                             December 15, 1997
Your ref.:


Ladies and Gentlemen:

We have acted as counsel to LCC International, Inc., a corporation organized
under the laws of Delaware ("LCC"), and LCC Europe AS (former European
Technology Partner AS), a corporation organized under the laws of Norway
("LCCE") in connection with the execution and delivery of that certain Second
Amended and Restated Credit Agreement dated as of 15 December 1997 (the "Credit
Agreement") among LCC, LCCE, LCC Design Services, L.L.C., LCC Development
Company, L.L.C., Microcell Management, Inc., each of the lenders signatory
thereto and the Chase Manhattan Bank, as Administrative Agent. Except as
otherwise defined herein, all terms used herein and defined in the Credit
Agreement shall have the meanings assigned to them therein.

In connection with this opinion, we have examined executed copies of the Credit
Agreement, the Revolving Credit Facility and the Security Agreement dated 16
June 1996 executed by LCCE in favor of LCC (collectively, the "Documents") and
such other documents, records, agreements and certificates as we have deemed
appropriate. We have also reviewed such matters of law as we have considered
relevant for the purpose of this opinion.

Based upon the foregoing, we are of the opinion that:

1.       LCCE is duly incorporated, validly existing and in good standing under
         Norwegian law, has the corporate power and authority to own its assets
         and to transact the business in which it is now engaged or proposed to
         be engaged.

2.       The execution, delivery and performance by LCCE of the Documents to
         which it is a party and the borrowings by LCCE under the Documents have
         been duly authorized by all necessary corporate actions and do not and
         will not: (a) require any consent or approval of its stockholder; (b)
         contravene its Articles of Association; (c) violate any provision of,
         or require any filing, registration, consent or approval under, any
         Norwegian law, rule, regulation (including without limitation, any
         exchange control law or regulation),

<PAGE>   107
         order, writ, judgment, injunction, decree, determination or award
         presently in effect having applicability to LCCE; (d) result in a
         breach of or constitute a default or require any consent under any
         indenture or loan or credit agreement or any other agreement, lease or
         instrument to which LCCE is a party or by which it or its Properties
         may be bound or affected; (e) result in, or require, the creation or
         imposition of any Lien, upon or with respect to any of the Properties
         now owned or hereafter acquired by LCCE; or (f) cause LCCE to be in
         default under any such law, rule, regulation, order, writ, judgment,
         injunction, decree, determination or award or any such indenture,
         agreement, lease or instrument. According to Norwegian Law a
         joint-stock company may not be liable, by debt or guarantee
         commitments, for a foreign parent company's liabilities. The agreements
         are only valid or binding, if, and to the extent, the Norwegian
         subsidiary is the actual borrower.

3.       Each Document has been duly executed and delivered by LCCE. Each
         Document to which LCCE is a party is a legal, valid and binding
         obligation of LCCE enforceable against LCCE in accordance with its
         terms, except to the extent that such enforcement may be limited by
         applicable bankruptcy, insolvency or other similar laws affecting
         creditors' rights generally.

4.       The choice of law provisions in each of the Documents would be enforced
         by the courts of Norway, provided that any such choice of law provision
         or enforcement provision is contrary to mandatory Norwegian law.

5.       To the best of our knowledge (after due inquiry), there are no actions,
         suits or proceedings pending or threatened, against or affecting LCCE
         before any Governmental Authority.

6.       No withholding tax or documentary stamp tax or intangible tax or any
         other tax under the applicable laws or Norway is or will be due in
         connection with the transactions contemplated under the Documents.

7.       LCCE is not subject to regulation under any statute or regulation
         limiting its ability to incur indebtedness for money borrowed as
         contemplated by the Documents.

8.       We hereby confirm that Mr. Piyush Sodha as Chairman of the Board of
         Directors of LCCE is authorized to execute and sign the Documents on
         behalf of LCCE.

9.       The opinions hereby expressed are confirmed to and given on the basis
         of Norwegian law as currently in force and applied by the Courts of
         Norway. We have made no investigation of and express no opinions as to
         the laws of any jurisdiction other than Norway.

                       Yours sincerely WIKBORG, REEN & CO.

                                LITIGATION, ETC.

1.       Katyl v. LCC. L.L.C., Arco No.-96-042-3, EEOC No. 10B-95-0117. This
         case involves a charge of national origin discrimination (East Indian)
         filed on October 12, 1995. Ms. Katyl claims that she was denied
         promotions and ultimately laid off because of her nationality. If she
         prevails she would be entitled to back pay and benefits retroactively
         to her date of termination (9/12/95), compensatory and punitive damages
         capped at $300,000 and attorney fees. On September 30, 1997, the
         Company received notice from the EEOC that it had dismissed the claim
         and adopted the finding of the Arlington County Human Rights Commission
         that "no reasonable grounds" existed for the claim. Ms. Katyl may
         pursue her claim in federal or state court, provided the suit is filed
         on or before December 26,1997.

2.       Taylor v. LCC. Inc., ARCO No. 96-145-E, EEOC No. 10B-96-0082. On May
         15, 1996, former LCC employee Sherry Taylor filed a complaint with the
         Arlington County Human Rights Commission alleging sex discrimination
         and sexual harassment in violation of Chapter 31 of the Arlington
         County Code. The Company appears to have a meritorious defense, and the
         case remains pending with the Commission.

3.       GBR v. Eurofon Incorp. & Co. KG, (Landgericht Dusseldorf, Germany).
         Plaintiff Landlord filed a complaint against Eurofon seeking DM 110,000
         on breach of contract claim for failure to pay rent. Eurofon has filed
         a motion seeking postponement of the case until the Appellate Court in
         Dusseldorf decides a similar claim. The decision regarding postponement
         is pending.

4.       ABS Capital Partners ("ABS"). On November 27, 1996, the Company
         received a letter from an attorney purporting to represent ABS. The
         letter asserts, in substance, that ABS and Microcell Management, LCC
         had agreed that ABS would receive 75% of Microcell's membership in
         exchange for up to $10 million in capital funding from ABS, and that
         LCC had "interfered" with that agreement by refusing to approve the
         transaction under the terms of the joint venture agreement between LCC
         and the other Microcell shareholders. No correspondence has been
         received on this claim since January, 1997 and to our knowledge, no
         suit has been filed.

5.       LCI International/Trademark Claim. On November 6, 1996, the Company
         received a letter from counsel for LCI International, Inc. ("LCI")
         alleging that the Company's purported use of the names "LCC
         International" and "LCCI" violates LCI's rights to use the trademark
         "LCI International" in connection with the marketing, sale and
         distribution of telecommunications products and services. The company
         has responded to LCI's claims, and believes it has a meritorious
         defense. Sporadic correspondence continues on this matter. To our
         knowledge, no suit has been filed.

6.       RCC Consultants, Inc. v. LCC International. At Law No. 96-1395 (Circuit
         Court for the County of Arlington). On December 20, 1996, RCC
         Consultants, Inc. ("RCC") filed a motion for judgment against LCC
         seeking $88,000.00 on a breach of contract claim alleging that LCC had
         failed to pay for certain site acquisition services. LCC counterclaimed
         against RCC, alleging breach of and seeking damages in the amount of
         $25,000. The company believes it has a meritorious defense to RCC's
         claims.

7.       Armor Cape & Pond Inc. v. LCC International. At Law No. 162099 (Circuit
         Court for the County of Fairfax). On June 20, 1997 Armor Cape & Pond,
         Inc. ("ACP') filed a motion for judgment against LCC seeking $42,800,
         plus interest, on a breach of contract claim alleging that LCC had
         failed to pay for certain architectural and engineering services. The
         company believes it has a meritorious defense to all but $20,000 of the
         claim.
