change in the Reserve Percentage or the MLA Cost.

         (a) Requests for Borrowing. AHL, on behalf of the Borrowers, shall
give the Administrative Agent irrevocable prior written notice in the form
attached hereto as Exhibit B (a "Notice of Borrowing") not later than 11:00

<PAGE>   31


principal amount of $3,000,000 or a whole multiple of $100,000 in excess
thereof, (II) Base Rate Loans (other than Swingline Loans and European
Swingline Loans made as Base Rate Loans), be in an aggregate principal amount
of $2,000,000 and/or a whole multiple of $100,000 in excess thereof, and (III)
European Swingline Loans, be in an aggregate principal amount of $500,000 and
or a whole multiple of $50,000 in excess thereof, (D) if not a Foreign Currency
Loan, whether the Loans are to be LIBOR Rate Loans or Base Rate Loans, and (E)
in the case of a LIBOR Rate Loan, the duration of the Interest Period
applicable thereto. Notices received after 11:00 a.m. (Charlotte time) shall be
deemed received on the next Business Day. The Administrative Agent shall
promptly notify the Lenders of each Notice of Borrowing.

         (b) Disbursement of Revolving Loans. Not later than 1:00 p.m.
(Charlotte time) on the proposed borrowing date for any Revolving Loan to be
made in Dollars (or if such Revolving Loan is to be made in an Alternative
Currency, no later than 1:00 p.m. (local time in the country having such
Alternative Currency as its lawful currency ) on the proposed borrowing date as
is necessary for such funds to be received and transferred to the Borrowers for
same day value on the date of such borrowing), each Lender will make available
to the Administrative Agent, for the account of the Borrowers, at the
Correspondent or Loan Office designated by the Administrative Agent, in Dollars
or the Alternative Currency in which the Loan is to be made, and funds
immediately available to the Administrative Agent, such Lender's Commitment
Percentage of the Revolving Loans requested. The proceeds of each Dollar Loan
requested pursuant to this Section 2.2 shall be disbursed in immediately

relevant Borrower designated in the Accounts Designation Letter. The proceeds
of each Foreign Currency Loan requested pursuant to this Section 2.2 shall be
transferred by wire from the Loan Office or an account maintained by the
Administrative Agent at a Correspondent to the account of the Foreign Borrower
specified by AHL in its Notice of Borrowing. All costs incurred and paid by the

fees charged to the Administrative Agent and the Administrative Agent's own
wire transfer fees, shall be borne solely by the Borrowers and shall be paid or
reimbursed to the Administrative Agent immediately upon billing, or, at the
option of the Administrative Agent, shall be paid by deduction from the Loan
proceeds. Subject to Section 3.6 hereof, the Administrative Agent shall not be
obligated to disburse the proceeds of any Revolving Loan requested pursuant to
this Section 2.2 until each Lender shall have made available to the
Administrative Agent its applicable Commitment Percentage of such Revolving
Loan; provided, however, that the failure of a Lender to make available to the
Administrative Agent such Commitment Percentage shall not affect the obligation
of the Administrative Agent to disburse the proceeds of any Revolving Loan with
respect to that portion of such Loan as to which the Administrative Agent shall
have received the applicable Commitment Percentage.

         SECTION 2.3  Swingline Loan Subfacility.

Agreement (including, without limitation, satisfaction (or proper waiver) of
the applicable conditions precedent in Article IV hereof), First Union, in its
individual capacity, agrees to make certain revolving credit loans requested by
the Borrowers in Dollars to the Borrowers (each a "Swingline Loan" and,

until the Revolving Facility Termination Date for the purposes hereinafter set
forth; provided, however, that at any time


                                      -25-

<PAGE>   32

(i) the aggregate principal amount of Swingline Loans outstanding shall not
exceed the Swingline Committed Amount, and (ii) the aggregate principal amount
(reflecting the Assigned Dollar Value of any outstanding Foreign Currency
Loans) of all outstanding Revolving Loans (reflecting the Assigned Dollar Value
of any Letters of Credit payable in an Alternative Currency) plus the aggregate
principal amount of outstanding Swingline Loans plus the sum of the principal
amount of any drawings not reimbursed pursuant to Section 2.5(d) and the
undrawn amount of outstanding Letters of Credit (reflecting the Assigned Dollar
Value of such unreimbursed drawings made in an Alternative Currency or such
undrawn amount of any Letters of Credit payable in an Alternative Currency)
plus the Assigned Dollar Value of all outstanding European Swingline Loans
shall not exceed the Aggregate Commitment. Swingline Loans hereunder shall be
made as Base Rate Loans and may be repaid and reborrowed in accordance with the
provisions hereof.

         (b)      Swingline Loan Advances.

                  (i)   Notices; Disbursement. Whenever the Borrowers desire a
Swingline Loan advance hereunder AHL, on behalf of the Borrowers, shall give
written notice (or telephone notice promptly confirmed in writing) to the
Swingline Lender not later than 12:00 Noon (Charlotte time) on the Business Day
of the requested Swingline Loan advance. Each such notice shall be irrevocable
and shall specify (A) that a Swingline Loan advance is requested, (B) the date
of the requested Swingline Loan advance (which shall be a Business Day) and (C)
the principal amount of the Swingline Loan advance requested.

                  Each Swingline Loan shall be made as a Base Rate Loan and
shall mature as provided in subsection (b)(iii) below.

                  (ii)  Minimum Amounts. Each Swingline Loan advance made by the
Swingline Lender in response to a notice submitted by the Borrowers pursuant to
the first paragraph of this Section 2.3(b) shall be in a minimum principal
amount of $50,000 and in integral multiples of $50,000 in excess thereof (or
the remaining amount of the Swingline Committed Amount, if less).

                  (iii) Repayment of Swingline Loans. The principal amount of
all Swingline Loans shall be due and payable on the earlier of (A) the maturity
date specified by the Swingline Lender or (B) the Revolving Facility
Termination Date. The Swingline Lender may, at any time, in its sole
discretion, by written notice to the Borrowers and the Lenders, demand
repayment of its Swingline Loans by way of an advance under the Revolving
Facility, in which case the Borrowers shall be deemed to have requested a
Revolving Loan comprised solely of Base Rate Loans in the amount of such
Swingline Loans; provided, however, that any such demand shall be deemed to
have been given one Business Day prior to the Revolving Facility Termination
Date and on the date of the occurrence of any Event of Default described in
Section 10.1 and upon acceleration of the Obligations hereunder and the
exercise of remedies in accordance with the provisions of Section 10.2. Each
Lender hereby irrevocably agrees to make its pro rata share of each such
Revolving Loan in the amount, in the manner and on the date specified in the
preceding sentence notwithstanding (I) the amount of such borrowing may not
comply with the minimum amount for advances of Revolving Loans otherwise
required hereunder, (II) whether any conditions specified in Section 4.3 are
then satisfied, (III) whether a Default or an Event of Default then exists,
(IV) failure of any such request or deemed


                                      -26-

<PAGE>   33


request for a Revolving Loan to be made by the time otherwise required
hereunder, (V) whether the date of such borrowing is a date on which Revolving
Loans are otherwise permitted to be made hereunder or (VI) any termination of
the Revolving Facility relating thereto immediately prior to or
contemporaneously with such borrowing. In the event that any Revolving Loan
cannot for any reason be made on the date otherwise required above (including,
without limitation, as a result of the commencement of a proceeding under the
Bankruptcy Code with respect to any Borrower or any Subsidiary of any
Borrower), then each Lender hereby agrees that it shall forthwith purchase (as
of the date such borrowing would otherwise have occurred, but adjusted for any
payments received from such Borrower on or after such date and prior to such
purchase) from the Swingline Lender such participations in the outstanding
Swingline Loans as shall be necessary to cause each such Lender to share in
such Swingline Loans ratably based upon its Commitment Percentage of the
Aggregate Commitment (determined before giving effect to any termination of the
Revolving Facility pursuant to Section 2.7), provided that (A) all interest
payable on the Swingline Loans shall be for the account of the Swingline Lender
until the date as of which the respective participation is purchased and (B) at
the time any purchase of participations pursuant to this sentence is actually
made, the purchasing Lender shall be required to pay to the Swingline Lender,
to the extent not paid to the Swingline Lender by the Borrowers in accordance
with the terms of subsection (c)(ii) hereof, interest on the principal amount
of participation purchased for each day from and including the day upon which
such borrowing would otherwise have occurred to but excluding the date of
payment for such participation, at the rate equal to the Federal Funds Rate.

         (c)      Interest on Swingline Loans.

                  (i)   Subject to the provisions of Section 3.1, each Swingline
Loan shall bear interest at a per annum rate (computed on the basis of the
actual number of days elapsed over a year of 365 or 366 days, as the case may
be) equal to the Domestic Base Rate.

                  (ii)  Payment of Interest. Interest on Swingline Loans shall
be payable quarterly in arrears on the last Business Day of each calender
quarter, at such other times as the Swingline Lender may specify from time to
time, and on the Revolving Facility Termination Date.

         (d)      Swingline Note. The Swingline Loans shall be evidenced by a
duly executed promissory note (the "Swingline Note") of the Borrowers to the
Swingline Lender in substantially the form of Exhibit A-2.

         SECTION 2.4 Repayment of Revolving Loans.

         (a)      Repayment on Revolving Facility Termination Date. The
Borrowers shall repay the outstanding principal amount of all Revolving Loans
made to such Borrowers in full, together with all accrued but unpaid interest
thereon, on the Revolving Facility Termination Date.

         (b)      Mandatory Repayment of Excess Loans. If at any time the sum
of (i) the outstanding aggregate principal amount of all outstanding Revolving
Loans (after giving effect to the Assigned Dollar Value of any Foreign Currency
Loans) plus (ii) the sum of the principal amount of any drawings not reimbursed
pursuant to Section 2.5(d) and the undrawn amount of outstanding Letters


                                      -27-

<PAGE>   34


of Credit (reflecting the Assigned Dollar Value of such unreimbursed drawings
made in an Alternative Currency or such undrawn amount of any Letters of Credit
payable in an Alternative Currency) plus (iii) the outstanding aggregate
principal amount of all Swingline Loans and plus (iv) the Assigned Dollar Value
of all outstanding European Swingline Loans exceeds the Aggregate Commitment,
the Borrowers shall immediately repay such excess, and such payment shall be
applied in the following order: (i) first, to Swingline Loans; (ii) secondly,
to European Swingline Loans, (iii) thirdly, to Revolving Loans which are Base
Rate Loans; (iv) fourthly, to Revolving Loans made in Dollars which are LIBOR
Loans, and (v) finally, to Foreign Currency Loans (other than European
Swingline Loans). Each such repayment shall be accompanied by accrued interest
on the amount repaid and any amount required to be paid pursuant to Section 3.8
hereof.

         (c)      Mandatory Repayment and Reduction Upon Net Proceeds
Realization. At the time of and upon the consummation of any sale or other
disposition of assets producing Net Cash Proceeds in excess of $5,000,000 in
any single transaction or, together with all other sales or dispositions of
assets during the current Fiscal Year, $10,000,000, the Borrowers shall apply
all Net Cash Proceeds from such sale or other disposition (including all
amounts up to the $5,000,000 and $10,000,000 minimum triggering amounts) to
repay the Revolving Loans and the Swingline Loans and reduce the Aggregate
Commitment by the amount of such repayment, provided, however, that no
reduction in the Aggregate Commitment shall be required to the extent that the
Borrowers reinvest the Net Cash Proceeds of such disposition or casualty loss
in equipment used or useful in the business of the Borrowers or in a
acquisition permitted under Section 9.4 within one hundred eighty (180) days
after such disposition or casualty loss. The payment shall be applied in the
following order: (i) first to Swingline Loans; (ii) secondly, to European
Swingline Loans, (iii) thirdly, to Revolving Loans which are Base Rate Loans;
and (iv) fourthly, to Revolving Loans made in Dollars which are LIBOR Loans,

Loans) based upon the Assigned Dollar Value as of the date of such payment.

         (d)      Optional Repayments and Commitment Reductions. Subject to
Section 2.4(e) below, without fee or penalty, the Borrowers may at any time and
from time to time repay the Revolving Loans made thereto, in whole or in part,
upon irrevocable notice to the Administrative Agent not later than 11:00 a.m.
(Charlotte time) on the date of repayment with respect to Base Rate Loans, at
least three (3) Business Days before with respect to LIBOR Rate Loans, and at
least four (4) Business Days before with respect to Foreign Currency Loans,
specifying the date and amount of repayment and whether the repayment is of
Base Rate Loans, LIBOR Rate Loans, or Foreign Currency Loans, or a combination
thereof, and, if of a combination thereof, the amount allocable to each. Upon
receipt of such notice, the Administrative Agent shall promptly notify each
Lender. If any such notice is given, the amount specified in such notice shall
be due and payable on the date set forth in such notice. Partial repayments
shall be in an aggregate amount of $3,000,000 or a whole multiple of $100,000
in excess thereof with respect to LIBOR Rate Loans or Foreign Currency Loans
(other than European Swingline Loans), $2,000,000 or a whole multiple of
$100,000 in excess thereof with respect to Base Rate Loans (other than
Swingline Loans and European Swingline Loans made as Base Rate Loans), $500,000
or a whole multiple of $50,000 in excess thereof with respect to European
Swingline Loans, and $50,000 or a whole multiple of $50,000 in excess thereof
with respect to Swingline Loans. Each such repayment shall be accompanied by
any amount required to be paid pursuant to Section 3.8. Upon the repayment of
any Loan, the Borrowers, without fee or


                                      -28-

<PAGE>   35


penalty, upon irrevocable notice to the Administrative Agent at least five (5)
Business Days prior to the proposed Aggregate Commitment reduction, may reduce
the Aggregate Commitment for more or less than the repaid Loan amount, but with
such Aggregate Commitment reduction to be in a minimum amount of $5,000,000 or
a whole multiple of $1,000,000 in excess thereof.

         (e)      Limitation on Repayment of LIBOR Rate Loans. No Borrower may
repay any LIBOR Rate Loan hereunder on any day other than on the last day of
the Interest Period applicable thereto unless such repayment is accompanied by
any amount required to be paid pursuant to Section 3.8.

         (f)      Pro-Rata Commitment Reductions. All repayments and Commitment
reductions made pursuant to this Section 2.4 shall be applied proportionally to
all Lenders based on each Lenders pro rata share of the Aggregate Commitment.

         SECTION 2.5 Letters of Credit.

         (a)      Issuance of Letters of Credit. Issuing Bank shall from time to
time, upon satisfaction (or proper waiver) of the applicable conditions
precedent in Article IV hereof, issue, extend or renew Letters of Credit that
are payable in Dollars or Alternative Currency for the account of each of the
Borrowers, upon such terms and conditions as Issuing Bank may then require;
provided that (i) the sum of the principal amount of any drawings not
reimbursed pursuant to Section 2.5(d) and the undrawn amount of outstanding
Letters of Credit (reflecting the Assigned Dollar Value of such unreimbursed
drawings made in an Alternative Currency or such undrawn amount of any Letters
of Credit payable in an Alternative Currency) shall at no time exceed the LOC
Committed Amount, and (ii) the sum of (A) the aggregate principal amount of
Revolving Loans outstanding (reflecting the Assigned Dollar Value of all
Foreign Currency Loans), (B) the sum of the principal amount of any drawings
not reimbursed pursuant to Section 2.5(d) and the undrawn amount of outstanding
Letters of Credit (reflecting the Assigned Dollar Value of such unreimbursed
drawings made in an Alternative Currency or such undrawn amount of any Letters
of Credit payable in an Alternative Currency), and (C) the aggregate principal
amount of outstanding Swingline Loans and (D) the Assigned Dollar Value of the
aggregate European Swingline Loans outstanding shall all at no time exceed the
Aggregate Commitment. No Letter of Credit shall have an original expiration
date more than one year from the date of issuance or that extends beyond the
Revolving Facility Termination Date. The joint and several reimbursement
obligations of the Borrowers under any such Letters of Credit are to be
Obligations hereunder, and the coming due of any reimbursement obligation under
any such Letter of Credit shall be deemed to be a request for a Revolving Loan
in the amount of such Obligation. If an Event of Default occurs or exists, or,
if at the Revolving Facility Termination Date, there is outstanding a Letter of
Credit that as originally issued or as extended had an expiry date extending
beyond the Revolving Facility Termination Date, Borrowers, on demand by the
Issuing Bank, are to deliver to the Administrative Agent good funds equal to
100% of the maximum liability under all outstanding Letters of Credit, which
funds are to be deposited in a separate, blocked account (the "Cash Collateral
Account") maintained by Borrowers with the Administrative Agent and are to be
held in the Cash Collateral Account for the benefit of the Lenders as cash
collateral for the Borrowers' joint and several reimbursement obligations and
the other Obligations. Without limiting any other provisions in this Agreement,
including the restrictions on the issuance, extension


                                      -29-

<PAGE>   36


or renewal of Letters of Credit set forth in Section 2.5(a) hereof, the parties
hereto hereby agree that if at any time the sum of the undrawn amount
(reflecting the Assigned Dollar Value of any Letters of Credit payable in an
Alternative Currency) of outstanding Letters of Credit exceeds the LOC
Committed Amount, Borrowers, on demand by the Issuing Bank, are to deliver to
the Administrative Agent good funds equal to 100% of the amount of such excess,
which funds are to be deposited in the Cash Collateral Account maintained by
Borrowers with the Administrative Agent and are to be held in the Cash
Collateral Account for the benefit of the Lenders as cash collateral for the
Borrowers' joint and several reimbursement obligations and the other
Obligations.

         (b)      Letter of Credit Fees. Upon the issuance, renewal or extension
of a Letter of Credit on or after the Closing Date, the Borrowers jointly and
severally agree to pay to the Administrative Agent, for the account of the
Lenders as set forth below, a fee (the "LOC Issuance Fee") with respect to the
undrawn amount of the Letter of Credit and such fee shall be paid by the
Borrowers in arrears on the last Business Day of each calendar quarter
commencing September 30, 1999, and on the Revolving Facility Termination Date,
based upon the average daily undrawn amount of such Letter of Credit multiplied
by the Applicable Margin for LIBOR Rate Loans in effect on the last day of
immediately preceding calender quarter (irrespective of whether any LIBOR Rate
Loans are then outstanding). Each Lender, upon the issuance, renewal or
extension of a Letter of Credit on or after the Closing Date, shall share in
the LOC Issuance Fee which shall be computed on the basis of a year of 360 days
and assessed for the actual number of days elapsed. The Borrowers jointly and
severally further agree to (I) pay to the Issuing Bank, for its own account,
the LOC Fronting Fee, payable by the Borrowers in arrears on the last Business
Day of each calendar quarter commencing September 30, 1999, and on the
Revolving Facility Termination Date, and (II) pay the to the Issuing Bank, for
its own account, such administrative and operational fees, charges, and
expenses customarily charged by the Issuing Bank with respect to the issuance,
handling, and administration of payment under Letters of Credit.

         (c)      Participation. To the extent that Issuing Bank has not been
reimbursed as required hereunder or under any such Letter of Credit, the
Administrative Agent shall notify each of the Lenders, and each such Lender
shall pay to the Administrative Agent for the Issuing Bank such Lender's
Commitment Percentage of the Revolving Loan made to pay such unreimbursed
drawing in same day funds on the day of notification by Issuing Bank of an
unreimbursed drawing pursuant to the provisions of subsection (d) hereof. The
obligation of each Lender to fund any Revolving Loan as provided above shall be
absolute and unconditional and shall not be affected by any dispute over the
propriety of payment under any Letter of Credit, the occurrence of a Default,
an Event of Default or any other occurrence or event. Any such reimbursement
shall not relieve or otherwise impair the joint and several obligations of the
Borrowers to reimburse Issuing Bank under any Letter of Credit, together with
interest on such reimbursement amounts as provided in subsection (d) hereof.

         (d)      Reimbursement. Issuing Bank will promptly notify the Borrowers
of any drawing under any Letter of Credit. Unless AHL, on behalf of the
Borrowers, shall immediately notify Issuing Bank that the Borrowers intend to
reimburse Issuing Bank for such drawing other than from proceeds of Revolving
Loans, the Borrowers shall be deemed to have requested that the Lenders make
Revolving Loans in the amount (and in the case of any such Letter of Credit
payable in an Alternative Currency, reflecting the Assigned Dollar Value of
such drawing) of such drawing as provided in


                                      -30-

<PAGE>   37


subsection (e) hereof on the related Letter of Credit, the proceeds of which
will be used to satisfy the related reimbursement obligations to Issuing Bank.
The Borrowers jointly and severally agree to reimburse Issuing Bank on the date
of drawing under any Letter of Credit (either with the proceeds of Revolving
Loans or otherwise) in immediately available funds. If the conditions for
making a Revolving Loan deemed requested pursuant to this Section 2.3(c) to
reimburse any Letter of Credit drawing have not been satisfied, and the
Administrative Agent in its sole discretion has not waived the unsatisfied
conditions for making the Revolving Loan but has not accelerated the payment
date of the Obligations pursuant to Section 10.2 hereof because of the
Borrowers' failure to reimburse such drawing, the Borrowers shall pay the
Letter of Credit drawing in full, or the unreimbursed amount of such drawing
shall bear interest at a rate per annum equal to (i) the higher of the U.S.
Prime Rate or the Federal Funds Rate plus 1/2 of 1% plus (ii) two percent (2%).
The Borrowers' reimbursement obligations hereunder shall be absolute and
unconditional under all circumstances irrespective of any rights of setoff,
counterclaim or defense to payment any Borrower may claim or have against
Issuing Bank, the Administrative Agent, the Lenders, the beneficiary of such
Letter of Credit or any other Person, including without limitation any defense
based on any failure of any Borrower or any Subsidiary of any Borrower to
receive consideration or the legality, validity or unenforceability of the
Letter of Credit. Issuing Bank will promptly notify the other Lenders of the
amount of any unreimbursed drawing and each Lender shall promptly pay to the
Administrative Agent for the account of Issuing Bank, in Dollars and in
immediately available funds, the amount of such Lender's Commitment Percentage
of such unreimbursed drawing and such payment shall be made or deemed made
pursuant to clause (e) below. Such payment shall be made on the day such notice
is received by such Lender from Issuing Bank if such notice is received at or
before 3:00 P.M. (Charlotte time); otherwise, such payment shall be made at or
before 1:00 P.M. (Charlotte time) on the Business Day next succeeding the day
such notice is received. If such Lender does not pay such amount to Issuing
Bank in full upon such request, such Lender shall, on demand, pay to the
Administrative Agent for the account of Issuing Bank interest on the unpaid
amount during the period from the date of such drawing until such Lender pays
such amount to Issuing Bank in full at a rate per annum equal to, if paid
within two (2) Business Days of the date that such Lender is required to make
payments of such amount pursuant to the preceding sentence, the Federal Funds
Rate and thereafter at a rate equal to the Domestic Base Rate. Each Lender's
obligation to make such payment to Issuing Bank, and the right of Issuing Bank
to receive the same, shall be absolute and unconditional, shall not be affected
by any circumstance whatsoever and without regard to the termination of this
Agreement or the Commitments hereunder, the existence of a Default or Event of
Default or the acceleration of the obligations of the Borrowers hereunder and
shall be made without any offset, abatement, withholding or reduction
whatsoever. Simultaneously with the making of each such payment by a Lender to
Issuing Bank, such Lender shall, automatically and without any further action
on the part of Issuing Bank or such Lender, acquire a participation in an
amount equal to such payment (excluding the portion of such payment
constituting interest owing to Issuing Bank) in the related unreimbursed
drawing portion of the LOC Obligation and in the interest thereon, and shall
have a claim against Borrowers with respect thereto.

         (e)      Repayment with Revolving Loans. On any day on which the
Borrowers shall have requested, or been deemed to have requested as provided in
(d) above, a Revolving Loan advance to reimburse a drawing under a Letter of
Credit, the Administrative Agent shall give notice to the Lenders that a
Revolving Loan has been requested or deemed requested by the Borrowers to be
made


                                      -31-

<PAGE>   38


in connection with a drawing under a Letter of Credit, in which case Lenders
shall severally make Revolving Loans to the Borrowers jointly and severally in
a principal amount for each Lender equal to such Lender's Commitment Percentage
of such Revolving Loan requested or deemed to be requested by the Borrowers.
Each Lender shall make available to the Administrative Agent, at the office of
the Administrative Agent in Dollars in funds immediately available to the
Administrative Agent, such Lender's Commitment Percentage of the Revolving
Loans requested, and the proceeds thereof shall be paid directly to Issuing
Bank for application to the respective LOC Obligations. Each such Lender hereby
irrevocably agrees to make its Commitment Percentage of each such Revolving
Loan immediately upon any such request or deemed request in the amount, in the
manner and on the date specified in the preceding sentence notwithstanding (i)
the amount of such borrowing may not comply with the minimum amount for
advances of Revolving Loans otherwise required hereunder, (ii) whether any
conditions specified Section 4.2 are then satisfied, (iii) whether a Default or
an Event of Default then exists, (iv) failure for any such request or deemed
request for Revolving Loans to be made by the time otherwise required
hereunder, (v) whether the date of such borrowing is a date on which Revolving
Loans are otherwise permitted to be made hereunder or (vi) any termination of
the Commitments relating thereto immediately prior to or contemporaneously with
such borrowing. In the event that any Revolving Loan cannot for any reason be
made on the date otherwise required above (including, without limitation, as a
result of the commencement of a proceeding under the Bankruptcy Code with
respect to any Borrower or any other Person obligated upon the Obligations),
then each such Lender hereby agrees that it shall forthwith purchase (as of the
date such borrowing would otherwise have occurred, but adjusted for any
payments received from the Borrowers on or after such date and prior to such
purchase) from Issuing Bank such participation in the outstanding LOC
Obligations as shall be necessary to cause each such Lender to share in such
LOC Obligations ratably (based upon the respective Commitment Percentages of
the Lenders (determined before giving effect to any termination of the
Commitments pursuant to Section 2.7)), provided that at the time any such
purchase of a participation is actually made, the purchasing Lender shall be
required to pay to Issuing Bank, to the extent not paid to the Issuing Bank by
the Borrowers in accordance with the terms of subsection (d) hereof, interest
on the principal amount of participation purchased for each day from and
including the day upon which such borrowing would otherwise have occurred to
but excluding the date of payment for such participation, if paid within two
(2) Business Days of the date of the Revolving Loan, at the Federal Funds Rate,
and thereafter at the Domestic Base Rate.

         (f)      Renewal, Extension. The renewal or extension of any Letter of
Credit shall, for purposes hereof, be treated in all respects the same as the
issuance of a new Letter of Credit hereunder.

         (g)      Uniform Customs and Practices. Issuing Bank may have the
Letters of Credit be subject to the Uniform Customs and Practices for
Documentary Credits, as published as of the date of issue by the International
Chamber of Commerce (the "UCP") that shall be specified in the Letter of
Credit, in which case the UCP may be incorporated therein and deemed in all
respects to be a part thereof.

         (h)      Indemnification; Nature of Issuing Bank's Duties.

                  (i)   In addition to its other obligations under this Section,
         the Borrowers jointly and severally shall and do hereby protect,
         indemnify, pay and save Issuing Bank and each Lender harmless from and
         against any and all claims, demands, liabilities, damages, losses,
         costs, charges and expenses (including reasonable attorneys' fees)
         that Issuing Bank or such Lender may incur or be subject to as a
         consequence, direct or indirect, of (A) the issuance of any Letter of
         Credit or (B) the failure of Issuing Bank to honor a drawing under a
         Letter of Credit as a result of any act or omission, whether rightful
         or wrongful, of any present or future de jure or de facto government
         or governmental authority (all such acts or omissions, herein called
         "Government Acts").

                  (ii)  As between the Borrowers and Issuing Bank, the Borrowers
         shall assume all risks of the acts, omission or misuse of any Letter
         of Credit by the beneficiary thereof, and Issuing Bank shall not be
         responsible (A) for the form, validity, sufficiency, accuracy,
         genuineness or legal effect of any document submitted by any party in
         connection with the application for and issuance of any Letter of
         Credit, even if any such document should in fact prove to be in any or
         all respects invalid, insufficient, inaccurate, fraudulent or forged,
         (B) for the validity or sufficiency of any instrument transferring or
         assigning or purporting to transfer or assign any Letter of Credit or
         the rights or benefits thereunder or proceeds thereof, in whole or in
         part, that may prove to be invalid or ineffective for any reason, (C)
         for errors, omissions, interruptions or delays in transmission or
         delivery of any messages, by mail, cable, telegraph, telex or
         otherwise, whether or not they be in cipher, (D) for any loss or delay
         in the transmission or otherwise of any document required in order to
         make a drawing under a Letter of Credit or of the proceeds thereof,
         and (E) for any consequences arising from causes beyond the control of
         Issuing Bank, including, without limitation, any Government Acts. None
         of the above shall affect, impair, or prevent the vesting of Issuing
         Bank's rights or powers hereunder.

                  (iii) In furtherance and extension and not in limitation of
         the specific provisions of the foregoing, any action taken or omitted
         by Issuing Bank or any Lender, under or in connection with any Letter
         of Credit or the related certificates, if taken or omitted in good
         faith, shall not put such Issuing Bank or such Lender under any
         resulting liability to the Borrowers or any of their Subsidiaries. It
         is the intention of the parties that this Agreement shall be construed
         and applied to protect and indemnify Issuing Bank and each Lender
         against any and all risks involved in the issuance of the Letters of
         Credit, all of which risks are hereby assumed by the Borrowers (on
         behalf of themselves and each of their Subsidiaries), including,
         without limitation, any and all Government Acts. Issuing Bank and the
         Lender shall not, in any way, be liable for any failure by Issuing
         Bank or anyone else to pay any drawing under any Letter of Credit as a
         result of any Government Acts or any other cause beyond the control of
         Issuing Bank.

                  (iv)  Nothing in this subsection (h) is intended to limit the
         joint and several reimbursement obligations of the Borrowers contained
         in subsection (d) above. The joint and


                                      -33-

<PAGE>   40


         several obligations of the Borrowers under this subsection (h) shall
         survive the termination of this Agreement. No act or omissions of any
         current or prior beneficiary of a Letter of Credit shall in any way
         affect or impair the rights of Issuing Bank or any Lender to enforce
         any right, power or benefit under this Agreement.

                  (v)   Notwithstanding anything to the contrary contained in
         this subsection (h), the Borrowers shall not have an obligation to
         indemnify Issuing Bank or any Lender in respect of any liability
         incurred by Issuing Bank or such Lender (A) arising solely out of the
         gross negligence or willful misconduct of Issuing Bank or such Lender,
         as determined by a court of competent jurisdiction, or (B) caused by
         Issuing Bank's failure to pay under any Letter of Credit after
         presentation to it of a request strictly complying with the terms and
         conditions of such Letter of Credit, as determined by a court of
         competent jurisdiction, unless such payment is prohibited by at law,
         regulation, court order or decree.

         (i)      Responsibility of Issuing Bank. It is expressly understood
and agreed that the obligations of Issuing Bank to the Lenders are only those
expressly set forth in this Agreement and that Issuing Bank shall be entitled
to assume with respect to any Revolving Loans requested or deemed to be
requested hereunder that the conditions precedent to borrowings set forth in
Section 4.3 have been satisfied; provided, however, that nothing set forth in
this Section 2.5 shall be deemed to prejudice the right of any Lender to
recover from Issuing Bank any amounts made available by such Lender to Issuing
Bank pursuant to this Section 2.5 in the event that it is determined by a court
of competent jurisdiction that the payment with respect to a Letter of Credit
constituted gross negligence or willful misconduct on the part of Issuing Bank.

         (j)      Conflict with Letter of Credit Documents. All documents and
instruments executed in connection with the issuance of any Letter of Credit
shall be interpreted in a manner to be consistent with, and not in conflict of,
this Agreement and the other Loan Documents, but in the event of any conflict
between the provisions of this Agreement and any document or instrument
executed in connection with the issuance of any Letter of Credit (including any
letter of credit application), the terms and provisions of this Agreement shall
control.

         SECTION 2.6 Revolving Notes. Each Lender's Revolving Loans and the
joint and several obligation of the Borrowers to repay the Revolving Loans made
thereto shall be evidenced by the Revolving Note executed by the Borrowers
payable to the order of such Lender representing the Borrowers' joint and
several obligation to pay such Lender's Commitment or, if less, the aggregate
unpaid principal amount of all Revolving Loans made and to be made by such
Lender to the Borrowers hereunder, plus interest and all other fees, charges
and other amounts due thereon. Each Revolving Note shall be dated the date
hereof and shall bear interest on the unpaid principal amount thereof at the
applicable interest rate per annum specified in Section 3.1.

         SECTION 2.7 Termination of Revolving Facility. The Lenders'
Commitments under Sections 2.1 and 2.2 shall terminate on the earlier of (a)
the Expiration Date or (b) the date of termination by the Administrative Agent
on behalf of the Lenders pursuant to Section 10.2(a).


                                      -34-

<PAGE>   41


         SECTION 2.8 Use of Proceeds. The Borrowers shall use the proceeds of
the Loans for working capital and general corporate requirements of the
Borrowers, including the payment of consideration in acquisitions and
investments permitted by this Agreement and the payment of certain fees and
expenses incurred in connection with the transactions contemplated hereby;
provided, that in the event any Borrower intends to use the proceeds of any of
the Loans hereunder to finance or refinance, directly or indirectly, an
acquisition of any Person (or the acquisition of (i) more than 50% of the
publicly traded securities (of any class) of any Person or (ii) any of the
publicly traded stock (of any class) of any Person after such Borrower or any
of its Subsidiaries shall have been required to file a Schedule 13D under the
Exchange Act, with respect to such stock), then unless such acquisition (or
such other acquisition) has been approved by the board of directors of such
Person or officers thereof duly authorized to do so, then notwithstanding any
other provision of this Agreement, each Lender shall have the right to assign
all of its interest in its Loans and Commitments under the Credit Facility,
after first offering such assignment of its interest to each of the other
Lenders, without the consent of the Administrative Agent or, if and to the
extent required under Section 12.7 AHL, provided that such assignment is made
within 90 days after the public announcement of such acquisition.

         SECTION 2.9 Security; Trust; Covenant to Pay; Reaffirmation of
Obligations, etc.

         (a)      Security. The Obligations of each Borrower shall be secured in
accordance with the terms of the applicable Security Documents.

         (b)      Trust. All assets, rights, interests and benefits which are
now or in future granted to or conferred upon the Security Trustee pursuant to
the German Security Documents, the UK Security Documents or otherwise
mortgaged, charged, assigned or granted to it under any German Security
Documents, UK Security Documents (or any other document required in connection
with the German Security Documents or the UK Security Documents) and all other
rights, powers and discretions granted to or conferred upon the Security
Trustee under the German Security Documents, the UK Security Documents (or any
other document required in connection with the German Security Documents or UK
Security Documents) shall be held by the Security Trustee in trust for the
Administrative Agent, the Issuing Bank and the Lenders from time to time in
accordance with the provisions of the relevant German Security Documents and UK
Security Documents and this Agreement. The trusts constituted by this clause
(b) shall come into existence on the date of this Agreement and shall remain in
full force and effect until:

                  (i)   all Obligations under this Agreement or any other Loan
         Document have been fully and finally discharged; and

                  (ii)  neither Issuing Bank nor any Lender is under any
         commitment, obligation or liability (whether actual or contingent) to
         make advances or provide any other financial accommodation under this
         Agreement or any other Loan Document, provided that, for the purpose
         of the rule against perpetuities, the perpetuity period applicable to
         the trusts constituted by clause (b) above of this Agreement shall be
         the period of 80 years less one day from the date of this Agreement.


                                      -35-

<PAGE>   42


         (c)      Covenant to Pay. Without prejudice to its respective
obligations to the Administrative Agent, the Issuing Bank and the Lenders under
this Agreement and the other Loan Documents, each Borrower undertakes to the
Security Trustee to pay to the Security Trustee on behalf of the Administrative
Agent, the Issuing Bank and the Lenders all amounts from time to time due and
payable by it for the account of the Administrative Agent, the Issuing Bank and
any Lender under any Loan Document to the extent not already paid and duly and
punctually to observe and perform all its obligations contained in each Loan
Document to which it is a party. Any payment made by the Borrowers to the
Security Trustee pursuant to the immediately preceding sentence, shall, to the
extent of such payment, also discharge such Borrowers' obligation to make such
payment to the Administrative Agent, the Issuing Bank or the Lender concerned.

         (d)      Reaffirmation of Obligations and Liens. Each of the Borrowers
does hereby reaffirm all of its indebtedness, obligations and liabilities to
the Administrative Agent and the Lenders under the Existing Security Documents
executed by it and does hereby reaffirm the grant of any and all Liens on its
property held by the Administrative Agent (for the benefit of the Lenders)
under such Existing Security Documents; provided, however, that nothing in this
Section 2.9(b) is intended, or shall be construed, to constitute a novation of
any such indebtedness, obligations or liabilities or to modify, affect, release
or otherwise impair the continuity or perfection of such Liens.

         (e)      Continued Effectiveness of Existing Security Documents. On the
Closing Date, each of the domestic Borrowers shall enter into the Confirmation
Agreement, pursuant to which, among other things, (i) each Borrower shall
confirm and agree that each of the Existing Security Documents shall, after
giving effect to the execution, delivery and performance of this Agreement and
the other Loan Documents executed on the Closing Date, (A) remain in full force
and effect, (B) guarantee or secure (as the case may be) all Obligations which
may now exist or hereafter arise, and (ii) certain provisions of the Existing
Security Documents shall be amended.

         SECTION 2.10  Maximum Borrower Liability.

         (a)      It is the intent of the Borrowers, the Administrative Agent,
the Lenders and any other Person holding any of the Obligations that each
Borrower's (other than AHL's) maximum obligations hereunder (such Borrower's
"Maximum Borrower Liability") in any case or proceeding referred to below (but
only in such a case or proceeding) shall not be in excess of:

                  (i)   in a case or proceeding commenced by or against such
Borrower under the Bankruptcy Code on or within one year from the date on which
any of the Obligations of such Borrower are incurred, the maximum amount that
would not otherwise cause the obligations of such Borrower hereunder (or any
other obligations of such Borrower to the Administrative Agent, the Lenders and
any other Person holding any of the Obligations) to be avoidable or
unenforceable against such Borrower under (A) Section 548 of the Bankruptcy
Code or (B) any state fraudulent transfer or fraudulent conveyance act or
statute applied in such case or proceeding by virtue of Section 544 of the
Bankruptcy Code; or

                  (ii)  in a case or proceeding commenced by or against such
Borrower under the Bankruptcy Code subsequent to one year from the date on
which any of the Obligations of such


                                      -36-

<PAGE>   43


Borrower are incurred, the maximum amount that would not otherwise cause the
obligations of such Borrower hereunder (or any other obligations of such
Borrower to the Administrative Agent, the Lenders and any other Person holding
any of the Obligations) to be avoidable or unenforceable against such Borrower
under any state fraudulent transfer or fraudulent conveyance act or statute
applied in any such case or proceeding by virtue of Section 544 of the
Bankruptcy Code; or

                  (iii) in a case or proceeding commenced by or against such
Borrower under any law, statute or regulation other than the Bankruptcy Code
relating to dissolution, liquidation, conservatorship, bankruptcy, moratorium,
readjustment of debt, compromise, rearrangement, receivership, insolvency,
reorganization or similar debtor relief from time to time in effect affecting
the rights of creditors generally (collectively, "Other Debtor Relief Law"),
the maximum amount that would not otherwise cause the obligations of such
Borrower hereunder (or any other obligations of such Borrower to the
Administrative Agent, the Lenders and any other Person holding any of the
Obligations) to be avoidable or unenforceable against such Borrower under such
Other Debtor Relief Law, including, without limitation, any state fraudulent
transfer or fraudulent conveyance act or statute applied in any such case or
proceeding. (The substantive state or federal laws under which the possible
avoidance or unenforceability of the obligations of any Borrower hereunder (or
any other obligations of such Borrower to the Administrative Agent, the Lenders
and any other Person holding any of the Obligations) shall be determined in any
such case or proceeding shall hereinafter be referred to as the "Avoidance
Provisions").

         (b)      To the extent set forth in Section 2.10(a), but only to the
extent that the Obligations of any Borrower hereunder, or the transfers made by
such Borrower under the Pledge Agreements, the Mortgage of Shares or the
Security Agreement, would otherwise be subject to avoidance under any Avoidance
Provisions if such Borrower is not deemed to have received valuable
consideration, fair value, fair consideration or reasonably equivalent value
for such transfers or obligations, or if such transfers or obligations of any
Borrower hereunder would render such Borrower insolvent, or leave such Borrower
with an unreasonably small capital or unreasonably small assets to conduct its
business, or cause such Borrower to have incurred debts (or to have intended to
have incurred debts) beyond its ability to pay such debts as they mature, in
each case as of the time any of the obligations of such Borrower are deemed to
have been incurred and transfers made under such Avoidance Provisions, then the
obligations of such Borrower hereunder shall be reduced to that amount which,
after giving effect thereto, would not cause the Obligations of such Borrower
hereunder (or any other obligations of such Borrower to the Administrative
Agent, the Lenders or any other Person holding any of the Obligations), as so
reduced, to be subject to avoidance under such Avoidance Provisions. This
Section 2.10(b) is intended solely to preserve the rights hereunder of the
Administrative Agent, the Lenders and any other Person holding any of the
Obligations to the maximum extent that would not cause the obligations of the
Borrowers hereunder to be subject to avoidance under any Avoidance Provisions,
and no Borrower nor any other Person shall have any right, defense, offset, or
claim under this Section 2.10(b) as against the Administrative Agent, the
Lenders or any other Person holding any of the Obligations that would not
otherwise be available to such Person under the Avoidance Provisions.

         (c)      Each Borrower agrees that the Obligations may at any time and
from time to time exceed the Maximum Borrower Liability of such Borrower, and
may exceed the aggregate Maximum


                                      -37-

<PAGE>   44


Borrower Liability of all Borrowers hereunder, without impairing this Agreement
or any provision contained herein or affecting the rights and remedies of the
Lenders and the Administrative Agent hereunder.

         (d)      In the event any Borrower (a "Funding Borrower") shall make
any payment or payments under this Agreement or shall suffer any loss as a
result of any realization upon any collateral granted by it to secure its
obligations hereunder, each other Borrower (each, a "Contributing Borrower")
shall contribute to such Funding Borrower an amount equal to such payment or
payments made, or losses suffered, by such Funding Borrower determined as of
the date on which such payment or loss was made multiplied by the ratio of (i)
the Maximum Borrower Liability of such Contributing Borrower (without giving
effect to any right to receive any contribution or other obligation to make any
contribution hereunder), to (ii) the aggregate Maximum Borrower Liability of
all Borrowers (including the Funding Borrowers) hereunder (without giving
effect to any right to receive, or obligation to make, any contribution
hereunder). Nothing in this Section 2.10(d) shall affect each Borrower's joint
and several liability to the Administrative Agent and the Lenders for the
entire amount of its Obligations. Each Borrower covenants and agrees that its
right to receive any contribution hereunder from a Contributing Borrower shall
be subordinate and junior in right of payment to all obligations of the
Borrowers to the Administrative Agent and Lenders hereunder.

         (e)      Notwithstanding anything to the contrary appearing herein or
in the other Loan Documents, no Foreign Borrower shall be liable with respect
to the Obligations except for (i) the principal, interest, and other amounts
owing with respect to Loans made under the European Swingline Facility; (ii)
the principal, interest, and other amounts owing with respect to Revolving
Loans or Swingline Loans made to, and Letters of Credit issued for the benefit
of, one or more of the Foreign Borrowers; (iii) the costs incurred by the
Administrative Agent or any Lender in enforcing obligations of the Foreign
Borrowers; and (iv) the maximum principal amount at any time outstanding under
all Foreign Subsidiary Notes executed by such Foreign Borrower.

         SECTION 2.11 Waiver of Subrogation. Except for the contribution
provided for in Section 2.10(d) above, each Borrower hereby waives, to the
fullest extent possible, as against each other Borrower and its assets, any and
all rights, whether at law, in equity, by agreement or otherwise, to
subrogation, indemnity, reimbursement, contribution, or any other similar
claim, cause of action or remedy that otherwise would arise out of such
Borrower's payment or performance of the Obligations. The preceding waiver is
intended by each Borrower, the Lenders and the Administrative Agent to be for
the benefit of each other Borrower and any of their successors or assigns as an
absolute defense, other than under Section 2.10(d), to any action by any such
Borrower against any other Borrower or its assets.

         SECTION 2.12  European Swingline Loans.

         (a)      European Swingline Commitment. Subject to the terms and
conditions of this Agreement, the European Swingline Lender agrees to make
European Swingline Loans to the Foreign Borrowers (but with each of the
Borrowers, including, without limitation, each of the Foreign Borrowers,
jointly and severally obligated to repay such Loans) from time to time from the
Closing Date through the European Swingline Termination Date as requested by
the Foreign Borrowers, in


                                      -38-

<PAGE>   45


accordance with the terms of Section 2.12(b); provided, that (a) the Assigned
Dollar Value of all outstanding European Swingline Loans (after giving effect
to any amount requested) when added to the sum of (i) the aggregate principal
amount (reflecting the Assigned Dollar Value of any outstanding Foreign
Currency Loans) of all outstanding Revolving Loans plus (ii) the sum of the
principal amount of any drawings not reimbursed pursuant to Section 2.5(d) and
the undrawn amount of outstanding Letters of Credit (reflecting the Assigned
Dollar Value of such unreimbursed drawings made in an Alternative Currency or
such undrawn amount of any Letters of Credit payable in an Alternative
Currency) plus (iii) the aggregate principal amount of any outstanding
Swingline Loans, shall not exceed the Aggregate Commitment, and (b) the
Assigned Dollar Value of all outstanding European Swingline Loans (after giving
effect to any amount requested) shall not exceed the European Swingline
Committed Amount. Subject to the terms and conditions hereof the Foreign
Borrowers may borrow, repay and reborrow Revolving Loans hereunder until the
European Swingline Termination Date.

         (b)      Procedure for Advances of European Swingline Loans.

                  (i)   Notices; Disbursement. The Foreign Borrowers shall give
the European Swingline Lender notice of their intention to borrow (A) not later
than 11:00 a.m. (London time) at least three (3) Business Days before each
European Swingline Loan in the case of European Swingline Loans to be made as
LIBOR Rate Loans and (B) not later than 12:00 p.m. (London time) on the date of
the borrowing in the case of European Swingline Loans to be made as Base Rate
Loans, and such notice shall be in the form required by the European Swingline
Lender from time to time, and the European Swingline Lender shall advance funds
to a bank account of the Foreign Borrower in London pursuant to procedures
approved by the European Swingline Lender from time to time.

         Each European Swingline Loan shall be made as a Base Rate Loan or
LIBOR Rate Loans as provided in Section 3.1, shall bear interest as Base Rate
Loans or LIBOR Rate Loans as provided in Section 3.1 and shall mature as
provided in subsection (b)(iii) below.

                  (ii)  Minimum Amounts. Each European Swingline Loan advance
made by the European Swingline Lender in response to a notice submitted by a
Foreign Borrower pursuant to the first paragraph of this Section 2.12(b) shall
be in a minimum principal amount of $100,000 and in integral multiples of
$50,000 in excess thereof (or the remaining amount of the European Swingline
Committed Amount, if less).

                  (iii) Repayment of European Swingline Loans. The principal
amount of all European Swingline Loans shall be due and payable on the earlier
of (A) the maturity date specified by the European Swingline Lender (which, in
the case of any European Swingline Loans made as LIBOR Rate Loans, shall be the
last day of the interest period applicable to such Loan or such earlier date
pursuant to the proviso contained in this sentence), or (B) the Revolving
Facility Termination Date. The European Swingline Lender may, at any time, in
its sole discretion, by written notice to the Foreign Borrowers and the
Lenders, demand repayment of any of its European Swingline Loans by way of an
advance under the Revolving Facility (except that the European Swingline Lender
may not demand repayment of any European Swingline Loans made as LIBOR Rate
Loans prior to the


                                      -39-

<PAGE>   46


expiration of the last day of the interest period applicable to such Loans
unless either of the conditions set forth in the proviso contained in this
sentence have occurred), in which case (I) such European Swingline Loans shall
be converted on such maturity date to Loans payable in Dollars at the Assigned
Dollar Value of the outstanding amount of such European Swingline Loans and
shall bear interest thereafter at a rate per annum equal to the rate then
applicable to Base Rate Loans made in Dollars, and (II) the Borrowers shall be
deemed to have requested a Revolving Loan comprised solely of Base Rate Loans
in the amount of such converted European Swingline Loans; provided, however,
that any such demand shall be deemed to have been given one Business Day prior
to the Revolving Facility Termination Date and on the date of the occurrence of
any Event of Default described in Section 10.1 and upon acceleration of the
Obligations hereunder and the exercise of remedies in accordance with the
provisions of Section 10.2. Each Lender hereby irrevocably agrees to make its
pro rata share of each such Revolving Loan in the amount, in the manner and on
the date specified in the preceding sentence notwithstanding (I) the amount of
such borrowing may not comply with the minimum amount for advances of Revolving
Loans otherwise required hereunder, (II) whether any conditions specified in
Section 4.3 are then satisfied, (III) whether a Default or an Event of Default
then exists, (IV) failure of any such request or deemed request for a Revolving
Loan to be made by the time otherwise required hereunder, (V) whether the date
of such borrowing is a date on which Revolving Loans are otherwise permitted to
be made hereunder or (VI) any termination of the Revolving Facility relating
thereto immediately prior to or contemporaneously with such borrowing. In the
event that any Revolving Loan cannot for any reason be made on the date
otherwise required above (including, without limitation, as a result of the
commencement of a proceeding under the Bankruptcy Code with respect to any
Borrower or any Subsidiary of any Borrower), then each Lender hereby agrees
that it shall forthwith purchase (as of the date such borrowing would otherwise
have occurred, but adjusted for any payments received from such Borrower on or
after such date and prior to such purchase) from the European Swingline Lender
such participations in the outstanding European Swingline Loans as shall be
necessary to cause each such Lender to share in such European Swingline Loans
ratably based upon its Commitment Percentage of the Aggregate Commitment
(determined before giving effect to any termination of the Revolving Facility
pursuant to Section 2.7), provided that (A) all interest payable on the
European Swingline Loans shall be for the account of the European Swingline
Lender until the date as of which the respective participation is purchased and
(B) at the time any purchase of participations pursuant to this sentence is
actually made, the purchasing Lender shall be required to pay to the European
Swingline Lender, to the extent not paid to the European Swingline Lender by
the Borrowers in accordance with the terms of this subsection (b)(iii) hereof,
interest on the principal amount of participation purchased for each day from
and including the day upon which such borrowing would otherwise have occurred
to but excluding the date of payment for such participation, at the rate equal
to the Federal Funds Rate.

         (c)      Swingline Note. The European Swingline Loans shall be
evidenced by a European Swingline Note duly executed by all of the Borrowers.

         SECTION 2.13 Liability Unconditional.

                  Each Domestic Borrower hereby agrees that such Borrower is
jointly and severally liable for the full and prompt payment (whether at stated
maturity, by acceleration or otherwise) and performance of, all Obligations
owed or hereafter owing to the Administrative Agent, Issuing Bank


                                      -40-

<PAGE>   47


and the Lenders by each other Borrower. Each Domestic Borrower agrees that its
liability shall be absolute and unconditional, irrespective of, and unaffected
by,

                  (i)   the genuineness, validity, regularity, enforceability or
         any future amendment of, or change in, this Agreement, any other Loan
         Document or any other agreement, document or instrument to which any
         Borrower is or may become a party;

                  (ii)  the absence of any action to enforce this Agreement
         (including this Section 2.13) or any other Loan Document or the waiver
         or consent by the Administrative Agent or the Lenders with respect to
         any of the provisions thereof;

                  (iii) the existence, value or condition of, or failure to
         perfect its Lien against, any security for the Obligations or any
         action, or the absence of any action, by the Administrative Agent or
         any Lender in respect thereof (including the release of any such
         security);

                  (iv)  the insolvency of any Borrower; or

                  (v)   any other action or circumstances which might otherwise
         constitute a legal or equitable discharge or defense of a surety or
         guarantor,

it being agreed by each Domestic Borrower that its obligations as confirmed
under this Section 2.13 shall not be discharged until the payment and
performance, in full, of the Obligations has occurred. Each Domestic Borrower
expressly waives all rights it may have now or in the future under any statute,
or at common law, or at law or in equity, or otherwise, to compel the
Administrative Agent or any Lender to marshall assets or to proceed in respect
of the Obligations guaranteed hereunder against any other Borrower, any other
party or against any security for the payment and performance of the
Obligations before proceeding against, or as a condition to proceeding against,
such Domestic Borrower. It is agreed among each Domestic Borrower, the
Administrative Agent, the Issuing Bank and the Lenders that the foregoing
waivers are of the essence of the transaction contemplated by this Agreement
and the other Loan Documents and that, but for the provisions of this Section
2.13 and such waivers, each Lender would decline to enter into this Agreement.

                                  ARTICLE III

                            GENERAL LOAN PROVISIONS

         SECTION 3.1  Interest.

         (a)      Interest Rate Options. Loans made on the Closing Date shall be
made only as Base Rate Loans and shall bear interest at a rate equal to (i) the
Domestic Base Rate, if such Loans constitute Revolving Loans made in Dollars or
Swingline Loans, or (ii) the Foreign Base Rate, if such Loans constitute
European Swingline Loans made as Base Rate Loans in the Base Rate Currency.
Thereafter, (A) Base Rate Loans shall bear interest at a rate equal to (i) the
Domestic Base Rate, if such Loans constitute Revolving Loans made in Dollars or
Swingline Loans, or (ii) the Foreign Base Rate, if such Loans constitute
European Swingline Loans made as Base Rate Loans in the Base Rate


                                      -41-

<PAGE>   48


Currency, and (B) LIBOR Rate Loans (which shall include all Revolving Loans
made as Foreign Currency Loans, and any European Swingline Loans made in
Alternative Currencies other than Europeans Swingline Loans made as Base Rate
Loans in the Base Rate Currency) shall bear interest at the LIBOR Rate plus the
Applicable Margin (the "Applicable Margin") as set forth below in this Section
3.1. On behalf of the Borrowers, AHL shall determine whether a Revolving Loan
is to be a Foreign Currency Loan, Base Rate Loan or LIBOR Rate Loan and select
the Interest Period, if any, applicable to such Loan at the time a request for
borrowing is given or at the time a Notice of Conversion/Continuation is given
pursuant to Section 3.2. Any Revolving Loan or any portion thereof as to which
the Company has not duly specified an interest rate as provided herein shall,
(x) if it is a Loan made in Dollars, be deemed a Base Rate Loan, and (y) if it
is a Revolving Loan made as a Foreign Currency Loan, be deemed a LIBOR Rate
Loan having an interest period of one month. Any LIBOR Rate Loan for which an
interest Period has ended, shall, so long as no Event of Default has occurred
and shall be continuing, be deemed renewed as a LIBOR Rate Loan in the currency
in which the LIBOR Rate Loan was repayable (unless it is a Foreign Currency
Loan made in German deutsche marks, which shall be paid in full at the end of
such Interest Period), and have an Interest Period of one month, provided that
no Event of Default shall arise as a result thereof.

         For the avoidance of doubt and without limiting the foregoing, (i) any
borrowings under the Revolving Facility made in an Alternative Currency
(including English Pounds) shall be made by the Lenders solely as LIBOR Rate
Loans, (ii) any borrowings under the European Swingline Facility made in an
Alternative Currency (other than English Pounds) shall be made by the European
Swingline Lender solely as LIBOR Rate Loans having an Interest Period of one
month or as otherwise acceptable to the European Swingline Lender, and (iii)
any borrowings under the European Swingline Facility made in English Pounds
shall be made by the European Swingline Lender as Foreign Base Rate Loans or,
if acceptable to the European Swingline Lender, as LIBOR Rate Loans having an
Interest Period of one month or as otherwise acceptable to the European
Swingline Lender.

         (b)      Interest Periods. In connection with each LIBOR Rate Loan
(and except as otherwise provided in Section 2.12(b) with respect to European
Swingline Loans), AHL, on behalf of the Borrowers for Revolving Loans, by
giving notice at the times required hereunder, shall elect an interest period
(each, an "Interest Period") to be applicable to such Loan, which Interest
Period shall, be a period of one, two, three, or six months; provided that:

                  (i)   the Interest Period shall commence on the date of
         advance of or conversion to LIBOR Rate Loan and, in the case of
         immediately successive Interest Periods, each successive Interest
         Period shall commence on the date on which the next preceding Interest
         Period expires;

                  (ii)  if any Interest Period would otherwise expire on a day
         that is not a Business Day, such Interest Period shall expire on the
         next succeeding Business Day; provided, that, with respect to any
         LIBOR Rate Loan, if any Interest Period would otherwise expire on a
         day that is not a Business Day but is a day of the month after which
         no further Business Day occurs in such month, such Interest Period
         shall expire on the next preceding Business Day;


                                      -42-

<PAGE>   49



                  (iii) with respect to any LIBOR Rate Loan, any Interest
         Period that begins on the last Business Day of a calendar month (or on
         a day for which there is no numerically corresponding day in the
         calendar month at the end of such Interest Period) shall end on the
         last Business Day of the calendar month at the end of such Interest
         Period;

                  (iv)  no Interest Period for Revolving Loans shall extend
         beyond the Revolving Facility Termination Date;

                  (v)   at any time there shall be no more than ten Tranches of
         LIBOR Rate Loans (excluding European Swingline Loans made as LIBOR
         Rate Loans) under the Revolving Facility, no more than five of which
         Tranches may be Foreign Currency Loans (excluding European Swingline
         Loans made as LIBOR Rate Loans); for purposes of this provision, a
         "Tranch" of Loan shall refer to Loans with Interest Periods beginning
         and ending on the same date;

                  (vi)  such right of election is subject to Section 3.1(f);

                  (vii) European Swingline Loans made as LIBOR Rate Loans shall
         have an interest period of one month or as otherwise acceptable to the
         European Swingline Lender; and

                  (viii) at any time there shall be no more than six (6)
         Tranches of European Swingline Loans made as LIBOR Rate Loans
         (including the Existing LIBOR Rate Loans); for purposes of this
         provision, a "Tranch" of Loan shall refer to European Swingline Loans
         with Interest Periods beginning and ending on the same date.

         (c)      Initial Applicable Margin. The Applicable Margin provided for
in Section 3.1(a) shall initially be set at 1.625% for the period commencing on
the Closing Date through (but not including) the earlier of: (i) the date which
is five (5) Business Days after receipt by the Administrative Agent of the
financial statements for the third fiscal quarter of AHL and its Subsidiaries
ending on September 30, 1999, required to be delivered by Borrowers pursuant to
Section 6.1(a) hereof, together with the Officer's Compliance Certificate
required to be delivered pursuant to Section 6.2 hereof in connection with such
financial statements; and (ii) the date which is five (5) Business Days after
receipt by the Administrative Agent of an officer's certificate setting forth
the ratio of Consolidated Total Indebtedness to Consolidated Pro Forma Adjusted
EBITDA for AHL and its Subsidiaries calculated on a pro forma basis required to
be delivered pursuant to Section 9.4(g)(v).

         (d)      Applicable Margin. Base Rate Loans under the Revolving
Facility shall always bear interest at the Domestic Base Rate, without any
additional applicable margin. European Swingline Loans shall always bear
interest at (A) if made as Base Rate Loans, the Foreign Base Rate which, as
defined, represents a margin over the base rate quoted publicly by HSBC Plc
(formerly named Midland Bank, plc), and (B) if made as LIBOR Rate Loans, at the
LIBOR Rate plus the Applicable Margin. Except as provided in Section 3.1(c)
above, the Applicable Margin with respect to such LIBOR Rate Loans shall be
determined on the earlier of (A) at the end of each fiscal quarter hereof by
reference to the ratio of Consolidated Total Indebtedness of AHL and its
Subsidiaries as of the end of such fiscal quarter to Consolidated Pro Forma
Adjusted EBITDA for AHL and its Subsidiaries for


                                      -43-

<PAGE>   50


the period of four (4) consecutive fiscal quarters ending on the last day of
such fiscal quarter, and (B) where the Borrowers are required to deliver an
officer's certificate under Section 9.4(g)(v) in connection with the
consummation of an acquisition, by reference to the ratio of Consolidated Total
Indebtedness of AHL and its Subsidiaries as of the most recently ended fiscal
quarter to Consolidated Pro Forma Adjusted EBITDA for AHL and its Subsidiaries
for the period of four (4) consecutive fiscal quarters ending on the last day
of such fiscal quarter (calculated on a pro forma basis in accordance with said
Section), in each case, as follows:

                  All adjustments to the Applicable Margin shall be made by the
                  Administrative Agent as provided in Section 3.1(e) below.

         (e)      Adjustments to Applicable Margin. Adjustments, if any, in the
Applicable Margin shall be made by the Administrative Agent five (5) Business
Days after receipt by the Administrative Agent of (i) quarterly financial
statements for AHL and its Subsidiaries and the accompanying Officer's
Compliance Certificate setting forth the ratio of Consolidated Total
Indebtedness to Consolidated Pro Forma Adjusted EBITDA for AHL and its
Subsidiaries as of the most recent fiscal quarter end (calculated as provided
in subsection (d) above), and (ii) each officer's certificate setting forth the
ratio of Consolidated Total Indebtedness to Consolidated Pro Forma Adjusted
EBITDA for AHL and its Subsidiaries calculated on a pro forma basis required to
be delivered pursuant to Section 9.4(g)(v). Subject to Section 3.1(f), in the
event AHL fails to deliver such financial statements and certificate within the
time required by Section 6.2 or Section 9.4(g)(v), as applicable, the
Applicable Margin shall be the highest Applicable Margin set forth above until
five (5) Business Days after the delivery of such financial statements and
certificate.

         (f)      Default Rate. Upon the occurrence and during the continuance
of an Event of Default, (i) the Borrowers shall no longer have the option to
request LIBOR Rate Loans, Swingline


                                      -44-

<PAGE>   51


Loans and Foreign Currency Loans, (ii) all outstanding LIBOR Rate Loans shall
bear interest at a rate per annum equal to two percent (2%) in excess of the
rate then applicable to LIBOR Rate Loans until the end of the applicable
Interest Period and thereafter shall bear interest at a rate equal to two
percent (2%) in excess of the rate then applicable to Base Rate Loans made in
Dollars and, if Foreign Currency Loans under the Revolving Facility are
outstanding, and the acceleration rights under Section 10.2(a) shall have been
exercised by the Administrative Lender, such Foreign Currency Loans shall be
converted on the date of acceleration to Loans payable in Dollars at the
Assigned Dollar Value of the outstanding amount of the Loans and shall bear
interest thereafter at a rate per annum equal to two percent (2%) in excess of
the rate then applicable to Base Rate Loans made in Dollars, and (iii) all
other Loans shall bear interest at a rate per annum equal to two percent (2%)
in excess of the rate then applicable to Base Rate Loans made in Dollars.
Interest shall continue to accrue on the Notes after the filing by or against
any Borrower of any petition seeking any relief in bankruptcy or under any act
or law pertaining to insolvency or debtor relief, whether state, federal or
foreign.

         (g)      Interest Payment and Computation. Interest on each Base Rate
Loan and LIBOR Rate Loan shall be payable in arrears on each Interest Payment
Date and on the Revolving Facility Termination Date. Interest on Base Rate
Loans and Foreign Currency Loans made in the Base Rate Currency shall be
computed on the basis of a year of 365 or 366 days, as the case may be, and
assessed for the actual number of days elapsed, and interest on all other Loans
shall be computed on the basis of a year of 360 days and assessed for the
actual number of days elapsed.

         (h)      Maximum Rate. In no contingency or event whatsoever shall the
aggregate of all amounts deemed interest hereunder or under any of the Notes
charged or collected pursuant to the terms of this Agreement or pursuant to any
of the Notes exceed the highest rate permissible under any Applicable Law which
a court of competent jurisdiction shall, in a final determination, deem
applicable hereto. In the event that such a court determines that the Lenders
have charged or received interest hereunder in excess of the highest applicable
rate, the rate in effect hereunder shall automatically be reduced to the
maximum rate permitted by Applicable Law and the Lenders shall at the
Administrative Agent's option promptly refund to the applicable Borrower or
Borrowers any interest received by Lenders in excess of the maximum lawful rate
or shall apply such excess to the principal balance of the Obligations. It is
the intent hereof that the Borrowers not pay or contract to pay, and that
neither the Administrative Agent nor any Lender receive or contract to receive,
directly or indirectly in any manner whatsoever, interest in excess of that
which may be paid by the Borrowers under Applicable Law.

         SECTION 3.2 Notice and Manner of Conversion or Continuation of Loans.
Provided that no Default or Event of Default has occurred and is then
continuing, the Borrowers, with respect to Revolving Loans, shall have the
option to (i) convert at any time all or any portion of their outstanding Base
Rate Loans in a principal amount equal to $2,000,000 or any whole multiple of
$100,000 in excess thereof into LIBOR Rate Loans, (ii) upon the expiration of
any Interest Period, convert all or any part of their outstanding LIBOR Rate
Loans in a principal amount equal to $1,000,000 or a whole multiple of $100,000
in excess thereof into Base Rate Loans, and (iii) upon the expiration of its
Interest Period, continue any LIBOR Rate Loan in a principal amount of
$2,000,000 or any whole multiple of $100,000 in excess thereof as a LIBOR Rate
Loan; provided, that the Borrowers shall not be entitled to continue, but shall
repay, such portion of any Foreign


                                      -45-

<PAGE>   52


Currency Loan that equals the Assigned Dollar Value Excess as of the end of the
Interest Period. Whenever the Borrowers desire to convert or continue Loans as
provided above, AHL, on behalf of the Borrowers, shall give the Administrative
Agent irrevocable prior written notice in the form attached hereto as Exhibit C
(a "Notice of Conversion/Continuation") not later than 11:00 a.m. (Charlotte
time or London time, respectively) three (3) Business Days before the Business
Day, in the case of a conversion to or a continuation of a LIBOR Rate Loan,
four (4) Business Days before the Business Day, in the case of a continuation
of a LIBOR Rate Loan that is a Foreign Currency Loan, and the same Business
Day, in the case of a conversion to a Base Rate Loan, on which a proposed
conversion or continuation of such Loan is to be effective specifying (i) the
Loans to be converted or continued and, with respect to any LIBOR Rate Loan to
be converted or continued, the last day of the current Interest Period
therefor, (ii) the effective date of such conversion or continuation (which
shall be a Business Day), (iii) the principal amount of such Loans to be
converted or continued and (iv) with respect to a continuation of Foreign
Currency Loan, the Alternative Currency and the Interest Period to be
applicable thereto. The Administrative Agent shall promptly notify the Lenders
of such Notice of Conversion/Continuation received with respect to Revolving

         SECTION 3.3  Fees.

         (a)      Facility Fee.

                  (i)   Payment of Facility Fee. Commencing on the Closing Date
         and continuing through and including the Revolving Facility
         Termination Date, the Borrowers shall pay to the Administrative Agent,
         for the account of the Lenders, a non-refundable facility fee (the
         "Facility Fee") on the average daily Aggregate Commitment of the
         Lenders outstanding at a rate per annum (the "Facility Fee
         Percentage") (based on a 360 day year), as set forth below in this
         Section 3.3(a). The Facility Fee shall be payable quarterly in arrears
         on the last Business Day of each calendar quarter commencing September
         30, 1999, and on the Revolving Facility Termination Date. Such
         Facility Fee shall be distributed by the Administrative Agent between
         the Lenders pro rata in accordance with the Lenders' respective
         Commitment Percentages.

                  (ii)  Initial Facility Fee Percentage. The Facility Fee
         Percentage shall initially be set at 0.375% for the period commencing
         on the Closing Date through (but not including) the date which is five
         (5) Business Days after receipt by the Administrative Agent of the
         financial statements for the third fiscal quarter of AHL and its
         Subsidiaries ending on September 30, 1999, required to be delivered by
         Borrowers pursuant to Section 6.1(a) hereof, together with the
         Officer's Compliance Certificate required to be delivered pursuant to
         Section 6.2 hereof in connection with such financial statements.

                  (iii) Determination of Facility Fee Percentage. Except as
         provided in clause (ii) of this Section 3.1(a), the Facility Fee
         Percentage shall be determined on the earlier of (A) at the end of
         each fiscal quarter hereof by reference to the ratio of Consolidated
         Total Indebtedness of AHL and its Subsidiaries as of the end of such
         fiscal quarter to Consolidated Pro Forma Adjusted EBITDA for AHL and
         its Subsidiaries for the period of four (4)

         consecutive fiscal quarters ending on the last day of such fiscal
         quarter, and (B) where the Borrowers are required to deliver an
         officer's certificate under Section 9.4(g)(v) in connection with the
         consummation of an acquisition, by reference to the ratio of
         Consolidated Total Indebtedness of AHL and its Subsidiaries as of the
         most recently ended fiscal quarter to Consolidated Pro Forma Adjusted
         EBITDA for AHL and its Subsidiaries for the period of four (4)
         consecutive fiscal quarters ending on the last day of such fiscal
         quarter (calculated on a pro forma basis in accordance with said
         Section), in each case, as follows:

                  All adjustments to the Facility Fee Percentage shall be made
                  by the Administrative Agent as provided in Section 3.3(a)(iv)
                  below.

                  (iv)  Adjustments to Facility Fee Percentage. Adjustments, if
         any, in the Facility Fee Percentage shall be made by the
         Administrative Agent five (5) Business Days after receipt by the
         Administrative Agent of (i) quarterly financial statements for AHL and
         its Subsidiaries and the accompanying Officer's Compliance Certificate
         setting forth the ratio of Consolidated Total Indebtedness to

         subsection (d) above), and (ii) each officer's certificate setting
         forth the ratio of Consolidated Total Indebtedness to Consolidated Pro
         Forma Adjusted EBITDA for AHL and its Subsidiaries calculated on a pro
         forma basis required to be delivered pursuant to Section 9.4(g)(v). If
         AHL fails to deliver such financial statements and certificate within
         the time required by Section 6.2 or Section 9.4(g)(v), as applicable,
         the Facility Fee Percentage shall be the highest Facility Fee
         Percentage set forth above until five (5) Business Days after the
         delivery of such financial statements and certificate.

         (b)      Agent's Fees. In order to compensate the Administrative Agent
for its obligations hereunder, the Borrowers jointly and severally agree to pay
to the Administrative Agent, for its own account, the fees set forth in the
Commitment Letter and related Summary of Terms and Conditions between First
Union, FUCM and AHL dated September ____, 1999 and the Fee Letter executed by
AHL in connection therewith (collectively, the "Term Sheet").

         (c)      Letter of Credit Fees. Borrowers jointly and severally agree
to pay the Letter of Credit fees as set forth in Section 2.5(b) hereof.

         SECTION 3.4 Manner of Payment.

         (a)      Revolving Loan Payments. Each Revolving Loan payment
(including repayments described in Article II) by any Borrower on account of
the principal of or interest on the Revolving Loans or of any fee, commission
or other amounts payable to the Lenders under this Agreement or any Note shall
be made in Dollars or, if such Revolving Loan was made as a Foreign Currency
Loan, in the applicable Alternative Currency, not later than 1:00 p.m. (local
time at the Loan Office specified with respect to the Loan) on the date
specified for payment under this Agreement to the Administrative Agent for the
account of the Lenders to be distributed pro rata among the Revolving Loans,
and among such Lenders in accordance with their respective Commitment
Percentages, as applicable, at the Administrative Agent's Office, in
immediately available funds, and shall be made without any set-off,
counterclaim or deduction whatsoever. Any payment received after such time but
before 2:00 p.m. (Charlotte time) on such day shall be deemed a payment on such
date for the purposes of Section 10.1, but for all other purposes shall be
deemed to have been made on the next succeeding Business Day. Any Revolving
Loan payment received after 2:00 p.m. (Charlotte time) shall be deemed to have
been made on the next succeeding Business Day for all purposes.

         (b)      European Swingline Loan Payments. Each Payment by a Borrower
on account of the principal of or interest on the European Swingline Loans or
of any fee, commission or other amounts payable to the European Swingline
Lender under this Agreement or the European Swingline Note shall be made not
later than 1:00 p.m. (local time of the Loan Office designated by the European
Swingline Lender to receive Loan repayments) on the date specified for payment
under this Agreement at the Loan Office, in immediately available funds, and
shall be made without any set-off, counterclaim or deduction whatsoever. Any
payment received after such time shall be deemed to have been made on the next
succeeding Business Day for all purposes. All payments of principal and
interest with respect to European Swingline Loans shall be repayable in the
Foreign Currency in which such European Swingline Loan was made.

         (c)      Business Days. If any payment under this Agreement or any
Note shall be specified to be made upon a day which is not a Business Day, it
shall be made on the next succeeding day which is a Business Day and such
extension of time shall in such case be included in computing any interest if
payable along with such payment.

         SECTION 3.5 Crediting of Payments and Proceeds. In the event that any
Borrower shall fail to pay any of the Obligations when due and the Obligations
have been accelerated pursuant to Section 10.2, all payments received by the
Lenders upon the Notes and the other Obligations and all


                                      -48-

<PAGE>   55


net proceeds from the enforcement of the Obligations shall be first applied to
all Administrative Agent's fees and expenses then due and payable, then to all
other expenses then due and payable by the Borrowers hereunder, then to all
indemnity obligations then due and payable by the Borrowers hereunder, then to
all Facility Fee and other fees and commissions then due and payable, then to
accrued and unpaid interest on the Notes, then to the principal amount of the
Notes (pro rata in accordance with all amounts due), and any termination
payments due in respect of a Hedging Agreement with any Lender (pro rata in
accordance with all such amounts due), in that order.

         SECTION 3.6 Nature of Obligations of Lenders Regarding Loans;
Assumption by Administrative Agent. The obligations of the Lenders under this
Agreement to make the Loans and to purchase participation interests in
Swingline Loans, Letters of Credit and European Swingline Loans pursuant to the
provisions of this agreement are several and are not joint or joint and
several. Unless the Administrative Agent shall have received notice from a
Lender prior to a proposed borrowing date that such Lender will not make
available to the Administrative Agent such Lender's ratable portion of the
amount to be borrowed on such date (which notice shall not release such Lender
of its obligations hereunder), the Administrative Agent may assume that such
Lender has made such portion available to the Administrative Agent on the
proposed borrowing date in accordance with Section 2.2 and the Administrative
Agent may, in reliance upon such assumption, make available to the Borrowers on
such date a corresponding amount. If such amount is made available to the
Administrative Agent on a date after such borrowing date, such Lender shall pay
to the Administrative Agent on demand an amount, until paid, equal to such
Lender's applicable Commitment Percentage of such borrowing and interest
thereon at a rate per annum equal to the daily average Federal Funds Rate
during such period as determined by the Administrative Agent. A certificate of
the Administrative Agent with respect to any amounts owing under this Section
shall be conclusive, absent manifest error. If such Lender's applicable
Commitment Percentage of such borrowing is not made available to the
Administrative Agent by such Lender within three (3) Business Days of such
borrowing date, the Administrative Agent shall be entitled to recover such
amount made available by the Administrative Agent with interest thereon at the
rate per annum then applicable to such Loan hereunder, on demand, from the
applicable Borrower or Borrowers. The failure of any Lender to make its
applicable Commitment Percentage of any Loan available shall not relieve it or
any other Lender of its obligation, if any, hereunder to make its applicable
Commitment Percentage of such Loan available on such borrowing date, but no
Lender shall be responsible for the failure of any other Lender to make its
applicable Commitment Percentage of such Loan available on the borrowing date.

         SECTION 3.7 Changed Circumstances.

         (a)      Circumstances Affecting Foreign Currency and LIBOR Rate
Availability. If the Administrative Agent, any Lender, or any Loan Office shall
determine that by reason of circumstances affecting the foreign exchange and
interbank markets generally, LIBOR deposits in Dollars or deposits in the
Alternative Currency are not being offered to the Person, then such Person
shall forthwith give notice thereof to AHL. Thereafter, until such Person
notifies AHL that such circumstances no longer exist, the obligation of the
Person to make the affected Loan, and the right of each of the Borrowers to
convert any Loan to the affected Loan or to continue any Foreign Currency Loan
or LIBOR Rate Loan or otherwise defer payment of any Loan, shall be suspended,


                                      -49-

<PAGE>   56


and each of the Borrowers shall repay in full (or cause to be repaid in full)
the then-outstanding principal amount of each such Loan, together with accrued
interest thereon and any payments required by Section 3.8 hereof.

         (b)      Laws Affecting Foreign Currency and LIBOR Rate Availability.
If, after the date hereof, the introduction of, or any change in, any
Applicable Law or any change in the interpretation or administration thereof by
any Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by the Administrative
Agent, any Lender or any Loan Office with any request or directive (whether or
not having the force of law) of any such Governmental Authority, central bank
or comparable agency, shall make it unlawful or impossible for the
Administrative Agent, any Lender, or any Loan Office to honor its obligations
hereunder to make or maintain any Foreign Currency Loan or LIBOR Rate Loan,
then such Person shall forthwith give notice thereof to AHL on behalf of the
Borrowers. Thereafter, until such Person notifies AHL on behalf of the
Borrowers that such circumstances no longer exist, the obligation of the Person
to make the affected Loan, and the right of each of the Borrowers to convert
any Loan to the affected Loan or to continue any Foreign Currency Loan or LIBOR
Rate Loan or otherwise defer payment of any Loan, shall be suspended, and each
of the Borrowers shall repay in full (or cause to be repaid in full) the
then-outstanding principal amount of each such Loan, together with accrued
interest thereon and any payments required by Section 3.8 hereof.

         (c)      Increased Costs. If, after the date hereof, the introduction
of, or any change in, any Applicable Law, or in the interpretation or
administration thereof by any Governmental Authority, central bank or
comparable agency charged with the interpretation or administration thereof, or
compliance by the Administrative Agent, any Lender, or the European Swingline
Lender (or any Loan Office) with any request or directive (whether or not
having the force of law) of such Governmental Authority, central bank or
comparable agency:

                  (i)   shall subject the Administrative Agent, any Lender, or
         the European Swingline Lender (or any Loan Office) to any tax, duty or
         other charge with respect to any Foreign Currency Loan, LIBOR Rate
         Loan, any Letter of Credit, or any Note or shall change the basis of
         taxation of payments to the Lender (or any Loan Office) of the
         principal of or interest on any Foreign Currency Loan, LIBOR Rate
         Loan, any Letter of Credit, or the Note or any other amounts due under
         this Agreement in respect thereof (except for changes in the rate of
         tax or any tax, duty, or other charge imposed on the overall net
         income of the Administrative Agent, any Lender, or the European
         Swingline Lender or any Loan Office imposed by the jurisdiction in
         which the Administrative Agent, any Lender, or the European Swingline
         Lender is organized or is or should be qualified to do business or
         such Loan Office is located); or

                  (ii)  shall impose, modify or deem applicable any reserve
         (including, without limitation, any imposed by the Bank of England or
         Board of Governors of the Federal Reserve System), special deposit,
         insurance or capital or similar requirement against assets of,
         deposits with or for the account of, or credit extended by the
         Administrative Agent, any Lender, or the European Swingline Lender(or
         any Loan Office) or shall impose on the Administrative Agent, any
         Lender, or the European Swingline Lender or any Loan Office or the
         foreign exchange and interbank markets any other condition affecting
         any Foreign


                                      -50-

<PAGE>   57


         Currency Loan, LIBOR Rate Loan, any Letter of Credit, or the Note; and
         the result of any of the foregoing is to increase the costs to the
         Lender of maintaining any Foreign Currency Loan, LIBOR Rate Loan, or
         Letter of Credit (after consideration of any changes in the Reserve
         Percentage) or to reduce the yield or amount of any sum received or
         receivable by the Lender under this Agreement or under the Note in
         respect of a Foreign Currency Loan, LIBOR Rate Loan, or Letter of
         Credit, then the affected Person shall promptly notify AHL of such
         fact and demand compensation therefor and, within fifteen (15) days
         after such notice, each of the Borrowers shall pay to such Person such
         additional amount or amounts as will compensate such Person for such
         increased cost or reduction. The Administrative Agent will promptly
         notify AHL of any event of which it has knowledge that will entitle
         any Person to compensation pursuant to this Section 3.7(c); provided,
         that the Administrative Agent shall incur no liability whatsoever to
         any of the Borrowers in the event it fails to do so. A certificate of
         the Administrative Agent setting forth the basis for determining such
         additional amount or amounts necessary to compensate the any Person
         shall be conclusively presumed to be correct absent manifest error. If
         any Person claims compensation under this Section, each of the
         Borrowers may at any time, upon at least four (4) Business Days' prior
         notice to the Administrative Agent, pay in full the affected Loan or
         substitute a letter of credit issued other than pursuant to this
         Agreement.

         SECTION 3.8 Indemnity. Each of the Borrowers does hereby indemnify
each of the Administrative Agent, any Lender, and the European Swingline Lender
against any loss or expense (including without limitation any foreign exchange
costs) which may arise or be attributable to the Lender's obtaining,
liquidating or employing deposits or other funds acquired to effect, fund or
maintain the Loans or the Issuing Bank's issuance or honor of a Letter of
Credit (i) as a consequence of any failure by any of the Borrowers to make any
payment when due of any amount due hereunder in connection with a Foreign
Currency Loan or a LIBOR Rate Loan, (ii) due to any failure of any of the
Borrowers to borrow on a date specified therefor in a Notice of Borrowing or
Notice of Continuation/Conversion with respect to any Foreign Currency Loan or
a LIBOR Rate Loan or (iii) due to any payment, prepayment or conversion of any
Foreign Currency Loan or LIBOR Rate Loan on a date other than the last day of
the Interest Period therefor. The Lender's calculations of any such loss or
expense shall be furnished to each of the Borrowers and shall be presumed to be
correct, absent manifest error.

         SECTION 3.9 Capital Requirements. If either (i) the introduction of,
or any change in, or in the interpretation of, any Applicable Law or (ii)
compliance with any guideline or request after the Closing Date from any
central bank or comparable agency or other Governmental Authority (whether or
not having the force of law), has or would have the effect of reducing the rate
of return on the capital of, or has affected or would affect the amount of
capital required to be maintained by the Administrative Agent, any Lender or
the European Swingline Lender or any corporation controlling such Person as a
consequence of, or with reference to the Commitment and other commitments of
this type, below the rate which the Person or such other corporation could have
achieved but for such introduction, change or compliance, then within five (5)
Business Days after written demand by any such Lender, each of the Borrowers
shall pay to such Person from time to time as specified by the Person
additional amounts sufficient to compensate (after consideration of any change
in the Reserve Percentage) the Administrative Agent, any Lender, or the
European Swingline Lender or other


                                      -51-

<PAGE>   58


corporation for such reduction. A certificate as to such amounts submitted to
each of the Borrowers by the Administrative Agent, any Lender, or the European
Swingline Lender shall, in the absence of manifest error, be presumed to be
correct and binding for all purposes.

         SECTION 3.10 Taxes; Currency.

         (a)      Payments Free and Clear. Any and all payments by each of the
Borrowers hereunder or under the Note shall be made free and clear of and
without deduction for any and all present or future taxes, levies, imposts,
deductions, charges or withholding, and all liabilities with respect thereto
excluding income and franchise taxes imposed by the jurisdiction under the laws
of which the Administrative Agent, any Lender, or the European Swingline Lender
is organized or is or should be qualified to do business or any political
subdivision thereof (all such non-excluded taxes, levies, imposts, deductions,
charges, with each of the Borrowers and liabilities being hereinafter referred
to as "Taxes"). If any of the Borrowers shall be required by law to deduct any
Taxes from or in respect of any sum payable hereunder or under any Note to the
Administrative Agent, any Lender, or the European Swingline Lender, (A) the sum
payable shall be increased as may be necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section 3.10) the Administrative Agent, any Lender, or the European
Swingline Lender receives an amount equal to the amount the Lender would have
received had no such deductions been made, (B) such Borrower shall make such
deductions, (C) such Borrower shall pay the full amount deducted to the
relevant taxing authority or other authority in accordance with Applicable Law,
and (D) such Borrower shall deliver to the Administrative Agent, any Lender, or
the European Swingline Lender evidence of such payment to the relevant taxing
authority or other authority in the manner provided in Section 3.10(d).

         (b)      Stamp and Other Taxes. In addition, each of the Borrowers
shall pay any present or future stamp, registration, recordation or documentary
taxes or any other similar fees or charges or excise or property taxes, levies
of the United States or any state or political subdivision thereof or any
applicable foreign jurisdiction which arise from any payment made hereunder or
from the execution, delivery or registration of, or otherwise with respect to,
this Agreement, the Loans, the other Loan Documents, or the perfection of any
rights in respect thereto (hereinafter referred to as "Other Taxes").

         (c)      Indemnity. Each of the Borrowers shall and does hereby
indemnify the Administrative Agent, any Lender, or the European Swingline
Lender for the full amount of Taxes and Other Taxes (including, without
limitation, any Taxes and Other Taxes imposed by any jurisdiction on amounts
payable under this Section 3.10) paid by such Lender or the Administrative
Agent (as the case may be) and any liability (including penalties, interest and
expenses) arising therefrom or with respect thereto, whether or not such Taxes
or Other Taxes were correctly or legally asserted. Such indemnification shall
be made within thirty (30) days from the date such Lender or the Administrative
Agent, any Lender, or the European Swingline Lender (as the case may be) makes
written demand therefor.

         (d)      Evidence of Payment. Within ten (10) days after the date of
any payment of Taxes or Other Taxes, the affected Borrower shall furnish to the
Administrative Agent, any Lender, or the


                                      -52-

European Swingline Lender, at its address referred to in Section 12.1, the
original or a certified copy of a receipt evidencing payment thereof or other
evidence of payment satisfactory to the Administrative Agent, the Lender, or
the European Swingline Lender

         (e)      If any Lender is incorporated or organized under the laws of
a jurisdiction other than the United States of America or any state thereof (a
"Non-U.S. Lender"), such Non-U.S. Lender will deliver to each of the
Administrative Agent and each of the Borrowers, on or prior to the Closing Date
(or, in the case of a Non-U.S. Lender that becomes a party to this Agreement as
a result of an assignment after the Closing Date, on the effective date of such
assignment), (i) in the case of a Non-U.S. Lender that is a "bank" for
purposes of Section 881(c)(3)(A) of the Internal Revenue Code, a properly
completed Internal Revenue Service Form 4224 or 1001, as applicable (or
successor forms), certifying that such Non-U.S. Lender is entitled to an
exemption from or a reduction of withholding or deduction for or on account of
United States federal income taxes in connection with payments under this
Agreement or any of the Notes, together with a properly completed Internal
Revenue Service Form W-8 or W-9, as applicable (or successor forms), and (ii)
in the case of a Non-U.S. Lender that is not a "bank" for purposes of Section
881(c)(3)(A) of the Internal Revenue Code, a certificate in form and substance
reasonably satisfactory to the Agent and each of the Borrowers and to the
effect that such Non-U.S. Lender (x) is not a "bank" for purposes of Section
881(c)(3)(A) of the Internal Revenue Code, is not subject to regulatory or
other legal requirements as a bank in any jurisdiction, and has not been
treated as a bank for purposes of any tax, securities law or other filing or
submission made to any governmental authority, any application made to a rating
agency or qualification for any exemption from any tax, securities law or other
legal requirements, (y) is not a 10-percent shareholder for purposes of Section
881(c)(3)(B) of the Internal Revenue Code and (z) is not a controlled foreign
corporation receiving interest from a related person for purposes of Section
881(c)(3)(C) of the Internal Revenue Code, together with a properly completed
Internal Revenue Service Form W-8 or W-9, as applicable (or successor forms).
Each such Non-U.S. Lender further agrees to deliver to each of the
Administrative Agent and the Borrower an additional copy of each such relevant
form on or before the date that such form expires or becomes obsolete or after
the occurrence of any event (including a change in its applicable Loan Office)
requiring a change in the most recent forms so delivered by it, in each case
certifying that such Non-U.S. Lender is entitled to an exemption from
withholding or deduction for or on account of United States federal income
taxes in connection with payments under this Agreement or any of the Notes,
unless an event (including, without limitation, any change in treaty, law or
regulation) has occurred prior to the date on which any such delivery would
otherwise be required, which event renders all such forms inapplicable or the
exemption to which such forms relate unavailable and such Non-U.S. Lender
notifies the Administrative Agent and the Borrower that it is not entitled to
receive payments without deduction or withholding of United States federal
income taxes. Each such Non-U.S. Lender will promptly notify the Administrative
Agent and each of the Borrowers of any changes in circumstances that would
modify or render invalid any claimed exemption or reduction.

         (f)      Survival. Without prejudice to the survival of any other
agreement of each of the Borrowers hereunder, the agreements and obligations of
each of the Borrowers contained in this Section 3.10 shall survive the payment
in full of the Obligations and the termination of the Commitments.

         (g)      Failure to Pay in Foreign Currency. If any of the Borrowers
is unable for any reason to effect payment of a Loan or to reimburse a drawing
under the Letter of Credit in the Alternative Currency as required by this
Agreement, the Administrative Agent, Issuing Bank, any Lender, or the European
Swingline Lender may require such payment to be made in Dollars in the Assigned
Dollar Value of such payment. In any case in which each of the Borrowers shall
make such payment in Dollars, such Borrower agrees to hold the Administrative
Agent, Issuing Bank, any Lender, or the European Swingline Lender harmless from
any loss incurred by the Administrative Agent, Issuing Bank, any Lender, or the
European Swingline Lender arising from any change in the value of Dollars in
relation to such Alternative Currency between the date such payment became due
and the date of payment thereof. Without limiting the generality of the
foregoing, if any of the Borrowers is unable for any reason to effect payment
of a Loan in the Alternative Currency as required by this Agreement or if any
of the Borrowers shall default in the payment of any Foreign Currency Loan
under the Revolving Facility, then the Borrowers shall be deemed to have
requested, and Lenders shall be deemed to have extended, a Base Rate Loan under
the Revolving Facility in an amount sufficient to purchase an amount of the
Alternative Currency sufficient to repay such Foreign Currency Loan in full.

         (h)      Judgment Currency. If for the purpose of obtaining judgment
in any court or enforcing any such judgment it is necessary to convert any
amount due in any Alternative Currency into any other currency, the rate of
exchange used shall be the Administrative Agent, any Lender, or the European
Swingline Lender's spot rate of exchange for the purchase of the Alternative
Currency with such other currency at the close of business on the Business Day
preceding the date on which judgment is given or any order for payment is made.
The obligation of each of the Borrowers in respect of any amount due from it
hereunder shall, notwithstanding any judgment or order for a liquidated sum or
sums in respect of amounts due hereunder or under any judgment or order in any
other currency or otherwise, be discharged only to the extent that on the
Business Day following receipt by the Administrative Agent, any Lender, or the
European Swingline Lender of any payment in a currency other than the
Alternative Currency, the Administrative Agent, any Lender, or the European
Swingline Lender is able (in accordance with normal banking procedures) to
purchase the Alternative Currency, with such other currency. If the amount of
the Alternative Currency that the Administrative Agent, any Lender, or the
European Swingline Lender is able to purchase with such other currency is less
than the amount due in the relevant Alternative Currency, notwithstanding any
judgment or order, each of the Borrower shall indemnify the Lender for the
shortfall.

         (i)      United Kingdom Tax Forms.

                  (A)   Each Lender that is not a United Kingdom Bank (as
         defined in Section 840A of the United Kingdom Income and Corporation
         Taxes Act of 1988) subject to United Kingdom corporation tax as
         respects interest payments to it pursuant to this Agreement (each a
         "Non-U.K. Bank") shall deliver to the United Kingdom Inland Revenue
         (whether directly, through the United States Internal Revenue Service
         or such other appropriate channels), with copies sent
         contemporaneously therewith to AHL and the Administrative Agent,
         within seven (7) Business Days after it becomes a Lender hereunder, a
         form 13-D or such other appropriate official form (each, a "U.K. Tax
         Form") duly completed and signed by such Lender establishing that such
         Non-U.K. Bank is entitled to exemption (regardless of such


                                      -54-

<PAGE>   61


         Lender's Lending Office) from United Kingdom tax treaty with the
         appropriate jurisdiction, or establishing that it is otherwise
         entitled to receive payments without such withholdings; provided,
         however, that no Non-U.K. Bank shall be required to furnish any such
         documentation under this subparagraph (A) if it is not entitled to
         claim an exemption from or reduced rate of withholding under
         applicable law. At any time a Non-U.K. Bank is not entitled to claim
         an exemption from or a reduced rate of withholding under applicable
         law, such Non-U.K. Bank shall so inform AHL the Administrative Agent.

                  (B)   Each Lender that is a United Kingdom Bank (as defined
         in Section 840A of the United Kingdom Income and Corporation Taxes Act
         of 1988) (each a "U.K. Bank") shall complete and deliver to AHL and
         the Administrative Agent a statement signed by an authorized signatory
         of such U.K. bank, and other documentation reasonably required to the
         effect that it is subject to United Kingdom corporation tax on
         interest payable to it pursuant to this Agreement.

                  (C)   No Borrower shall be required to pay any additional
         amount to any Non-U.K. Bank or U.K. Bank in respect of United Kingdom
         withholding taxes under this Section 3.10(i) if such Lender shall have
         failed to deliver (1) the U.K. Tax Form as required under subparagraph
         (A) in the case of a Non-U.K. Bank, or (2) the statement and other
         documentation under subparagraph (B) in the case of a U.K. Bank;
         provided, however, that if a Non-U.K. Bank shall not have a Lending
         Office in the United Kingdom and shall not be entitled to an exemption
         from United Kingdom withholding tax under a treaty, each as of the
         time of a given payment by any Borrower hereunder, then Section
         3.10(a) shall not apply with respect to such payment.

         SECTION 3.11 Special Lenders. Unless the Required Lenders seek
indemnification, payment, or reimbursement under, or invoke the provisions of,
Sections 3.7, 3.8, 3.9, or 3.10, if any Borrower is obligated to pay to the
Administrative Agent or any Lender any amount under said Sections, the
Borrowers may, so long as no Default or Event of Default then exists, replace
such Lender with a new Lender reasonably acceptable to the Administrative
Agent, and such Lender hereby agrees to be so replaced subject to the
following:

                  (a)       the obligations of the Borrowers hereunder to the
         Lender to be replaced (including such increased or additional costs
         incurred from the date of notice to the Borrowers of such increase or
         additional costs through the date such Lender is replaced hereunder)
         shall be paid in full to such Lender concurrently with such
         replacement;

                  (b)      The replacement Lender shall be a Lender that is not
         subject to the increased costs arising under such Sections which may
         have effectuated the Borrower's election to replace any Lender
         hereunder;

                  (c)      Each such replacement Lender shall execute and
         deliver to the Administrative Agent such documentation reasonably
         satisfactory to the Administrative Agent pursuant to which such Lender
         is to become a party hereto with a Commitment equal to that of the
         Lender being replaced and shall make a Loan or Loans in the aggregate
         principal amount


                                      -55-
<PAGE>   62
         equal to the aggregate outstanding principal amount of the Loan or
         Loans of the Lender being replaced;

                  (d) Upon such execution of such documents referred to in
         clause (c) and repayment of the amounts referred to in clause (a), the
         replacement Lender shall be a "Lender" with a Commitment as specified
         hereinabove and the Lender being replaced shall cease to be a "Lender"
         hereunder, except with respect to indemnification provisions under
         this Agreement, which shall survive as to such replaced Lender;

                  (e) The Administrative Agent shall reasonably cooperate in
         effectuating the replacement of any Lender hereunder, but at no time
         shall the Administrative Agent be obligated to initiate any such
         replacement; and

                  (f) Any Lender replaced hereunder shall be replaced at the
         Borrower's sole cost and expense and at no cost or expense to the
         Administrative Agent.

         SECTION 5.1 Representations and Warranties. To induce the
Administrative Agent and the Lenders to enter into this Agreement and to induce
the Lenders and the European Swingline Lender to make the Loans and the Issuing
Bank to issue, extend and renew the Letters of Credit, the Borrowers hereby
jointly and severally represent and warrant to the Administrative Agent, the
Lenders, the Issuing Bank and the European Swingline Lender that:

         (a) Organization; Power; Qualification. Each of AHL and its
Subsidiaries is duly organized, validly existing and in good standing under the
laws of the jurisdiction of its incorporation or formation, has the power and
authority to own its properties and to carry on its business as now being
conducted and is duly qualified and authorized to do business in each
jurisdiction where the failure to be so qualified or authorized could
reasonably be expected to have a Material Adverse Effect. The jurisdictions in
which AHL and its Subsidiaries are organized and qualified to do business as of
the Closing Date are described on Schedule 5.1(a). The address of the chief
executive office and principal place of business of each Borrower as of the
Closing Date is set forth on Schedule 5.1(a) hereto. Prior to the Closing Date,
Verfurth Dortmund and Verfurth Osnabruck merged with and into Munster, with
Munster being the surviving entity of such merger. Prior to the Closing Date,
Schulbert merged with and into Bocholt with Bocholt being the surviving entity
of such merger. Set


                                      -60-

listed on Schedule 5.1(b), (ii) the capitalization of each of the Subsidiaries
of AHL consists of the number of shares, authorized, issued and outstanding, of
such classes and series, with or without par value, described on Schedule
5.1(b), (iii) all outstanding shares have been duly authorized and validly
issued and are fully paid and nonassessable, (iv) the shareholders of each of
the Subsidiaries of AHL and the number of shares owned by each are described on
Schedule 5. 1 (b), (v) there are no outstanding stock purchase warrants,
subscriptions, options, securities, instruments or other rights of any type or
nature whatsoever, which are convertible into, exchangeable for or otherwise
provide for or permit the issuance of capital stock of any Subsidiaries of AHL,
except as described on Schedule 5.1(b), and (vi) Schedule 5.1(b) identifies
each Material Subsidiary of AHL.

         (c) Authorization of Agreement, Loan Documents and Borrowing. Each of
AHL and its Subsidiaries has the right, power and authority and has taken all
necessary corporate and other action to authorize the execution, delivery and
performance of this Agreement and each of the other Loan Documents to which it
is a party in accordance with their respective terms. This Agreement and each
of the other Loan Documents have been duly executed and delivered by the duly
authorized officers of AHL and each of its Subsidiaries party thereto and each
such document constitutes the legal, valid and binding obligation of AHL or its
Subsidiary party thereto, enforceable in accordance with its terms, except as
such enforcement may be limited by bankruptcy, insolvency, reorganization,
moratorium or similar state or federal debtor relief laws from time to time in
effect which affect the enforcement of creditors' rights in general and the
availability of equitable remedies.

         (d) Compliance of Agreement, Loan Documents and Borrowing with Laws,
Etc. The execution, delivery and performance by AHL and each of its
Subsidiaries of the Loan Documents to which each such Person is a party in
accordance with their respective terms, the borrowings hereunder and the
transactions contemplated hereby do not and will not, by the passage of time,
the giving of notice or otherwise, (i) except as set forth on Schedule 5.1(d)
hereto, require any Governmental Approval or violate any Applicable Law
relating to AHL or any of its Subsidiaries, (ii) conflict with, result in a
breach of or constitute a default under the articles of incorporation, bylaws
or other organizational documents of AHL or any of its Subsidiaries or any
Material Contract to which such Person is a party or by which any of its
properties may be bound or any Governmental Approval relating to such Person or
(iii) result in or require the creation or imposition of any Lien upon or with
respect to any material property now owned or hereafter acquired by such Person
other than Liens arising under the Loan Documents.

         (e) Compliance with Law; Governmental Approvals. Each of AHL and its
Subsidiaries (i) has all Governmental Approvals required by any Applicable Law
material to the conduct of its business and (ii) is in compliance with each
such Governmental Approval applicable to it and in compliance with all other
Applicable Laws relating to it or any of its respective properties, except
where the failure to be in such compliance could not reasonably be expected to
have a Material Adverse Effect. Each such Governmental Approval is in full
force and effect, is final and not subject


                                      -61-
<PAGE>   68


to review on appeal and is not the subject of any pending or, to the best

assessments and governmental charges or levies upon it and its property,
income, profits and assets which are due and payable, except where the payment
of such tax is being disputed in good faith and adequate reserves have been
established in accordance with GAAP. No Governmental Authority has asserted any
Lien or other claim against AHL or any Subsidiary thereof with respect to
material unpaid taxes which has not been discharged or resolved or is not being
contested in good faith. The charges, accruals and reserves on the books of AHL
and any of its Subsidiaries in respect of federal, state, local and other taxes

adequate, and the Borrowers do not anticipate any additional material taxes or
assessments for any of such years.

         (g) Environmental Matters. The properties of AHL and its Subsidiaries
are in compliance in all material respects with all applicable Environmental
Laws. There is no contamination at, under or about such properties or such
operations which could interfere in any material respect with the continued
operation of such properties or, except as set forth on Schedule 5.1(g), impair
in any material respect the fair saleable value thereof. Neither AHL nor any of
its Subsidiaries has received any written notice of material violation, alleged
violation, non-compliance, liability or potential liability regarding
environmental matters or compliance with Environmental Laws with regard to any
of its properties or the operations conducted in connection therewith, nor does
AHL nor any of its Subsidiaries have knowledge or reason to believe that any
such notice will be received or is being threatened.

         (h) ERISA.

                  (i) As of the Closing Date, neither any Borrower nor any
ERISA Affiliate maintains or contributes to, or has any obligation under, any
Employee Benefit Plans other than those identified on Schedule 5.1(h);

                  (ii) Each Borrower and each ERISA Affiliate is in material
compliance with all applicable provisions of ERISA and all other laws
applicable to any Employee Benefit Plans and the regulations and published
interpretations thereunder with respect to all Employee Benefit Plans except
for any required amendments for which the remedial amendment period as defined
in Section 401(b) of the Code has not yet expired. Each Employee Benefit Plan
that is intended to be qualified under Section 401(a) of the Code has been
determined by the Internal Revenue Service to be so qualified, and each trust
related to such plan has been determined to be exempt under Section 501(a) of
the Code. Each such Employee Benefit Plan has been operated in a manner to
preserve such qualification. No liability has been incurred by any Borrower or
any ERISA Affiliate which remains unsatisfied for any taxes or penalties with
respect to any Employee Benefit Plan or any Multiemployer Plan;


                                      -62-
<PAGE>   69


                  (iii) No Pension Plan has been terminated, nor has any
accumulated funding deficiency (as defined in Section 412 of the Code) been
incurred (without regard to any waiver granted under Section 412 of the Code),
nor has any funding waiver from the Internal Revenue Service been received or
requested with respect to any Pension Plan, nor has any Borrower or any ERISA
Affiliate failed to make any contributions or to pay any amounts due and owing
as required by Section 412 of the Code, Section 302 of ERISA or the terms of
any Pension Plan prior to the due dates of such contributions under Section 412
of the Code or Section 302 of ERISA, nor has there been any event requiring any
disclosure under Section 4041(c)(3)(C) or 4063(a) of ERISA with respect to any
Pension Plan;

                  (iv) Neither any Borrower nor any ERISA Affiliate has: (A)
engaged in a nonexempt prohibited transaction described in Section 406 of ERISA
or Section 4975 of the Code; (B) incurred any liability to the PBGC which
remains outstanding other than the payment of premiums and there are no premium
payments which are due and unpaid; (C) failed to make a required contribution
or payment to a Multiemployer Plan; or (D) failed to make a required install
ment or other required payment under Section 412 of the Code;

                  (v) The execution and delivery by Borrowers of this Agreement
and the borrowings hereunder will not involve any prohibited transaction under
ERISA or the Code;

                  (vi) No Termination Event has occurred or is reasonably
expected to occur; and

                  (vii) No material proceeding, claim, lawsuit and/or
investigation is existing or, to the best knowledge of any Borrower after due
inquiry, threatened concerning or involving any (A) employee welfare benefit
plan (as defined in Section 3(1) of ERISA) maintained or contributed to by any
Borrower or any ERISA Affiliate, (B) Pension Plan or (C) Multiemployer Plan.

         (i) Margin Stock. Neither AHL nor any Subsidiary thereof is engaged
principally or as one of its significant activities in the business of
extending credit for the purpose of "purchasing" or "carrying" any "margin
stock" (as each such term is defined or used in Regulation U of the Board of
Governors of the Federal Reserve System). No part of the proceeds of any of the
Loans will be used for purchasing or carrying margin stock or for any purpose
which violates, or which would be inconsistent with, the provisions of
Regulation T, U or X of such Board of Governors.

         (j) Government Regulation. Neither AHL nor any Subsidiary thereof is
an "investment company" or a company "controlled" by an "investment company"
(as each such term is defined or used in the Investment Company Act of 1940, as
amended) and neither AHL nor any Subsidiary thereof is, or after giving effect
to any Loan will be, a "Holding Company" or a "Subsidiary Company" of a
"Holding Company" or an "Affiliate" of a "Holding Company" within the
respective meanings of each of the quoted terms of the Public Utility Holding
Company Act of 1935 as amended, or any other Applicable Law which materially
limits its ability to incur or consummate the transactions contemplated hereby.

         (k) Patents, Copyrights and Trademarks. Each of AHL and its
Subsidiaries owns or possesses all patent, copyright and trademark rights which
are material to the conduct of its business


                                      -63-
<PAGE>   70


without infringing upon any validly asserted rights of others. No event has
occurred which permits, or after notice or lapse of time or both would permit,
the revocation or termination of any such rights. Except as set forth on
Schedule 5.1(k), neither AHL nor any of its Subsidiaries has been threatened
with any litigation regarding patents, copyrights or trademarks that would
present a material impediment to the business of AHL and its Subsidiaries,
taken as a whole.

         (l) Material Contracts. Schedule 5.1(1) sets forth a complete and
accurate list of all Material Contracts of AHL and its Subsidiaries in effect
as of the Closing Date not listed on any other Schedule hereto; other than as
set forth in Schedule 5.1(1), each of AHL and any Subsidiary thereof party
thereto has performed all of its material obligations under such Material
Contracts and, to the best knowledge of the Borrowers, each other party thereto
is in compliance in all material respects with each such Material Contract, and
each such Material Contract is, and after giving effect to the consummation of
the transactions contemplated by the Loan Documents will be, in full force and
effect in accordance with the terms thereof. AHL and its Subsidiaries have
delivered to the Administrative Agent a true and complete copy of each Material
Contract required to be listed on Schedule 5.1(1).

         (m) Employee Relations. As of the Closing Date, each of AHL and its
Subsidiaries is not, except as set forth on Schedule 5.1(m), party to any
collective bargaining agreement nor has any labor union been recognized as the
representative of its employees. AHL knows of no pending, threatened or
contemplated strikes, work stoppage or other collective labor disputes
involving its employees or those of its Subsidiaries.

         (n) Burdensome Provisions. Neither AHL nor any Subsidiary thereof is a
party to any indenture, agreement, lease or other instrument, or subject to any
corporate or partnership restriction, Governmental Approval or Applicable Law
which is so unusual or burdensome as in the foreseeable future could be
reasonably expected to have a Material Adverse Effect. AHL and its Subsidiaries
do not presently anticipate that future expenditures needed to meet the
provisions of any statutes, orders, rules or regulations of a Governmental
Authority will be so burdensome as to have a Material Adverse Effect.

         (o) Financial Statements. All balance sheets, statements of income,
retained earnings, stockholders' equity and cash flows, and all other financial
information of AHL and its Subsidiaries which have been furnished by the
Borrowers to the Administrative Agent and the Lenders for the purposes of or in
connection with this Agreement, including without limitation the financial
statements described in Section 4.2 (e), have been prepared in accordance with
GAAP consistently applied (except to the extent pro forma statements are based
upon reasonable estimates in accordance with Section 4.2(e)(ii)) throughout the
periods involved and present fairly in all material respects the matters
reflected therein subject, in the case of unaudited statements, to changes
resulting from normal year-end audit adjustments and items that would be
disclosed in footnotes to the audited statements. As of the Closing Date,
except as set forth on Schedule 5.1(o), neither AHL nor any of its Subsidiaries
has any contingent liability or liability for taxes, long-term leases or
unusual forward or long-term commitments which are not reflected in the
financial statements described above or in the notes thereto.


                                      -64-
<PAGE>   71


         (p) No Material Adverse Change. Since December 31, 1998, there has
been no material adverse change in the condition (financial or otherwise),
operations, properties, business or prospects of AHL and its Subsidiaries,
taken as a whole, including any event or condition that has had or is
reasonably likely to have a Material Adverse Effect.

         (q) Solvency. As of the Closing Date and after giving effect to each
Loan made hereunder, each of AHL and each of its Subsidiaries will be Solvent.

         (r) Titles to Properties. Each of AHL and its Subsidiaries has such
title to the real property owned or leased by it as is material to the conduct
of its business and good and marketable title to all of its personal property
material to its business as presently conducted, except such property as has
been disposed of by AHL or its Subsidiaries subsequent to such date which
dispositions have been in the ordinary course of business or as otherwise
expressly permitted hereunder. Schedule 5.1(r) hereto sets forth the address of
all real property owned or leased by a Borrower as of the Closing Date.

         (s) Liens. None of the properties and assets of AHL or any Subsidiary
thereof is subject to any Lien, except in each case Permitted Liens. No
financing statement under the Uniform Commercial Code of any state which names
AHL or any Subsidiary thereof or any of their respective trade names or
divisions as debtor and which has not been terminated, has been filed in any
state or other jurisdiction and neither AHL nor any Subsidiary thereof has
signed any such financing statement or any security agreement authorizing any
secured party thereunder to file any such financing statement, except to
perfect Permitted Liens. No filing or recording of any document or instrument
under the laws of the United Kingdom or the Federal Republic of Germany or any
jurisdiction thereof which names AHL or any Subsidiary thereof or any of their
respective trade names or divisions as debtor, chargor, assignor or mortgagor
and which has not been terminated, has been filed in the United Kingdom or the
Federal Republic of Germany or any jurisdiction thereof and neither AHL nor any
Subsidiary thereof has signed any pledge, mortgage, assignment, debenture or
any other form of security agreement authorizing any secured party thereunder
to file or record any such document, instrument or agreement, except to perfect
Permitted Liens.

         (t) Debt and Contingent Obligations. Schedule 5.1(t) is a complete and
correct listing as of the Closing Date of all Debt and Contingent Obligations
of AHL and its Subsidiaries. Each of AHL and its Subsidiaries have performed
and are in material compliance with all of the terms of such Debt and
Contingent Obligations and all instruments and agreements relating thereto, and
no default or event of default, or event or condition which with notice or
lapse of time or both would constitute such a default or event of default on
the part of AHL or its Subsidiaries exists with respect to any such Debt or
Contingent Obligation.

         (u) Litigation. Except as set forth on Schedule 5.1(u), as of the
Closing Date there are no actions, suits or proceedings pending nor, to the
knowledge of the Borrowers, threatened against or in any other way relating
adversely to or adversely affecting AHL or any Subsidiary thereof or any of
their respective properties in any court or before any arbitrator of any kind
or before or by any Governmental Authority which, if adversely determined, is
reasonably likely to have a Material Adverse Effect.


                                      -65-
<PAGE>   72


         (v) Franchise and License Fees. AHL and each of its Subsidiaries have
paid all material franchise, license or other fees and charges which have
become due pursuant to any Governmental Approval in respect of its business and
has made appropriate provision as is required by GAAP for any such fees and
charges which have accrued.

         (w) Absence of Defaults. No event has occurred or is continuing which
constitutes a Default or an Event of Default, or which constitutes, or which
with the passage of time or giving of notice or both would constitute, a
default or event of default by AHL or any Subsidiary thereof under any Material
Contract or judgment, decree or order to which AHL or its Subsidiaries is a
party or by which AHL or its Subsidiaries or any of their respective properties
may be bound.

         (x) Accuracy and Completeness of Information. All written information,
reports and other papers and data produced by or on behalf of AHL or any
Subsidiary thereof and furnished to the Lenders were, at the time the same were
so furnished, complete and correct in all material respects. No document
furnished or written statement made to the Agents or the Lenders by AHL or any
Subsidiary thereof in connection with the negotiation, preparation or execution
of this Agreement or any of the Loan Documents contains any untrue statement of
a fact material to the creditworthiness of AHL or its Subsidiaries or omits to
state a material fact necessary in order to make the statements contained
therein not misleading. AHL is not aware of any facts which it has not
disclosed in writing to the Administrative Agent having a Material Adverse
Effect, or insofar as AHL can now foresee, could reasonably be expected to have
a Material Adverse Effect.

         (y) Year 2000. The Borrowers have (i) undertaken a sufficient
inventory, review and assessment of all areas within their business and
operations that could be adversely affected by the failure of the Borrowers to
be Year 2000 Compliant on a timely basis, (ii) developed a plan and timeline
for becoming Year 2000 Compliant on a timely basis, (iii) to date, implemented
that plan in accordance with that timeline in all material respects, and (iv)
made inquiry of its key suppliers, vendors and customers as to whether such
person(s) will, on a timely basis, be Year 2000 Compliant in all material
respects and on the basis of such inquiry reasonably believes that all such
person(s) will be Year 2000 Compliant. "Year 2000 Compliant" shall means that,
in all material respects, all computer and software related applications shall
be able to recognize and perform properly, date sensitive functions involving
dates prior to and after December 31, 1999. The Borrowers shall take all action
necessary to ensure that the Borrowers shall be Year 2000 Compliant and that no
material adverse change will arise in the Borrowers' financial condition as a
result of its efforts or failure to be Year 2000 Compliant.

         SECTION 5.2 Survival of Representations and Warranties, Etc. All
representations and warranties set forth in this Article V and all
representations and warranties contained in any certificate or in any of the
Loan Documents (including without limitation, any such representation or
warranty made in or in connection with any amendment thereto) shall constitute
representations and warranties made under this Agreement. All representations
and warranties made under this Agreement (a) shall be made or deemed to be made
at and as of the Closing Date, as of each borrowing date and as of the date of
the issuance, renewal or extension of each Letter of Credit with the same
effect as if made on and as of the Closing Date, except to the extent that such
representations and warranties relate solely to an earlier date, in which case
such representations and warranties shall have been true and


                                      -66-
<PAGE>   73


correct on and as of such earlier date, (b) shall survive the Closing Date, and
(c) shall not be waived by the execution and delivery of this Agreement, any

any of its Affiliates, or (b) enter into, or be a party to, any transaction

         (c) Misrepresentation. Any representation or warranty made or deemed
to be made by any Borrower or any of its Subsidiaries under this Agreement, any

made, except to the extent that (i) an event or condition has occurred that
would cause a representation or warranty to be incorrect or misleading, (ii)
the occurrence of such event or condition and the representation or warranty to

<PAGE>   89


         SECTION 10.2 Remedies. Upon the occurrence and during the continuance
of an Event of Default, the Administrative Agent shall, upon the request and
direction of the Required Lenders, by notice to the Borrowers:

         (a) Acceleration: Termination of Facilities. Declare the principal of
and interest on the Loans and the Notes at the time outstanding, and all other
amounts owed to the Lenders, the European Swingline Lender, and to the
Administrative Agent under this Agreement or any of the other Loan Documents
and all other Obligations, to be forthwith due and payable, whereupon the same
shall immediately become due and payable without presentment, demand, protest
or other notice of any kind, all of which are expressly waived, anything in
this Agreement or the other Loan Documents to the contrary notwithstanding, and
terminate the Credit Facilities and the Commitments and any right of the
Borrowers to request borrowings thereunder; provided, that upon the occurrence
of an Event of Default specified in Section 10.1(h) or (i), the Credit
Facilities and the Commitments shall be automatically terminated and all
Obligations shall automatically become due and payable.

         (b) Rights of Collection. Exercise on behalf of the Lenders all of
their other rights and remedies under this Agreement, the other Loan Documents
and Applicable Law, in order to satisfy all of the Borrowers' Obligations.

         SECTION 10.3 Rights and Remedies Cumulative; Non-Waiver; etc. The
enumeration of the rights and remedies of the Administrative Agent and the
Lenders set forth in this Agreement is not intended to be exhaustive and the
exercise by the Administrative Agent and the Lenders of any right or remedy
shall not preclude the exercise of any other rights or remedies, all of which
shall be cumulative, and shall be in addition to any other right or remedy
given hereunder or under the Loan Documents or that may now or hereafter exist
in law or in equity or by suit or otherwise. No delay or failure to take action
on the part of the Administrative Agent or any Lender in exercising any right,
power or privilege shall operate as a waiver thereof, nor shall any single or
partial exercise of any such right, power or privilege preclude other or
further exercise thereof or the exercise of any other right, power or privilege
or shall be construed to be a waiver of any Event of Default. No course of
dealing between the Borrowers, the Administrative Agent and the Lenders or
their respective agents or employees shall be effective to change, modify or
discharge any provision of this Agreement or any of the other Loan Documents or
to constitute a waiver of any Event of Default. Notwithstanding anything to the
contrary set forth herein or in any other Loan Document, neither the
Administrative Agent nor any Lender shall exercise at any time during which no
Event of Default shall have occurred and be continuing any right or remedy with
respect to any of the Collateral, including, but not limited to, any right
granted in any Security Document to collect accounts receivable or to notify
account debtors.

         SECTION 10.4 Set-off. Except to the extent prohibited by law, in
addition to any rights now or hereafter granted under Applicable Law and not by
way of limitation of any such rights, upon and after the occurrence of any
Event of Default and during the continuance thereof, the Lenders and any
assignee or participant of a Lender in accordance with Section 12.7 are hereby
authorized by the Borrowers at any time or from time to time, without notice to
the Borrowers or to any other Person, any such notice being hereby expressly
waived, to set off and to appropriate and to apply any and all deposits
(general or special, time or demand, including, but not limited to,
indebtedness evidenced


                                      -83-
<PAGE>   90


by certificates of deposit, whether matured or unmatured, excluding government
securities required by Applicable Law to be held as security for worker's
compensation and similar claims and of whatever currency exchanged, if
necessary, at the Spot Rate to the currency of the Obligations) and any other
indebtedness at any time held or owing by the Lenders, or any such assignee or
participant to or for the credit or the account of the Borrowers against and on
account of the Obligations then due and payable.

         SECTION 10.5 Adjustments. If any Lender (a "Benefitted Lender") shall
at any time receive any payment of all or part of its Loans, or interest
thereon, or if any Lender shall at any time receive any Collateral in respect
to its Loans (whether voluntarily or involuntarily, by set-off or otherwise) in
a greater proportion than any such payment to and Collateral received by any
other Lender, if any, in respect of such other Lender's Loans, or interest
thereon, such Benefitted Lender shall, to the extent permitted by Applicable
Law, purchase for cash from the other Lenders such portion of each such other
Lender's Loans, or shall provide such other Lenders with the benefits of any
such Collateral, or the proceeds thereof, as shall be necessary to cause such
Benefitted Lender to share the excess payment or benefits of such Collateral or
proceeds ratably with each of the Lenders; provided, that if all or any portion
of such excess payment or benefits is thereafter recovered from such Benefitted
Lender, such purchase shall be rescinded, and the purchase price and benefits
returned to the extent of such recovery, but without interest. The Borrowers
agree that each Lender so purchasing a portion of another Lender's Loans may
exercise all rights of payment (including, without limitation, rights of
set-off) with respect to such portion as fully as if such Lender were the
direct holder of such portion.

         SECTION 10.6 Consents. The Borrowers acknowledge that certain
transactions contemplated by this Agreement and the other Loan Documents and
certain actions which may be taken by the Administrative Agent or the Lenders
in the exercise of their respective rights under this Agreement and the other
Loan Documents may require the consent of a Governmental Authority. If counsel
to the Administrative Agent reasonably determines that the consent of a
Governmental Authority is required in connection with the execution, delivery
and performance of any of the aforesaid documents or any documents delivered to
the Administrative Agent or the Lenders in connection therewith or as a result
of any action which may be taken pursuant thereto, then the Borrowers, at their
sole cost and expense, agree to use their reasonable best efforts to secure
such consent and to cooperate with the Administrative Agent and the Lenders in
any action commenced by the Administrative Agent or any Lender to secure such
consent.


                                   ARTICLE XI

                            THE ADMINISTRATIVE AGENT

         SECTION 11.1 Appointment. Each Lender hereby irrevocably appoints and
authorizes First Union to act as Administrative Agent hereunder and under the
other Loan Documents and to take such actions as agent on its behalf hereunder
and under the other Loan Documents, and to exercise such powers and to perform
such duties, as are specifically delegated to the Administrative Agent by the
terms hereof or thereof, together with such other powers and duties as are
reasonably incidental


                                      -84-
<PAGE>   91


thereto. Additionally, each Lender hereby appoints the Administrative Agent to
act as its agent and trustee in relation to the German Security Documents and
the UK Security Documents (in such capacity, the "Security Trustee") and
authorizes the Administrative Agent to enter into the German Security Documents
and the UK Security Documents on its behalf and to take such action on its
behalf and to exercise and enforce such rights, powers and discretions as are
expressly or by implication delegated to the Administrative Agent by the terms
of this Agreement, the German Security Documents and the UK Security Documents
and such rights and discretions as are reasonably incidental thereto. The
duties and functions of the Administrative Agent and the Security Trustee shall
be of an administrative nature only. Neither the Administrative Agent nor the
Security Trustee shall be deemed to be a trustee of any Lender except as
specified in this Agreement, the German Security Documents and the UK Security
Documents, nor shall the Administrative Agent or the Security Trustee be deemed
to be an agent or trustee of the Borrowers for any purpose. The Security
Trustee shall have no duties or obligations except those expressly set out in
this Agreement, the German Security Documents and the UK Security Documents.

         SECTION 11.2 Nature of Duties. The Administrative Agent shall have no
duties or responsibilities other than those expressly set forth in this
Agreement and the other Loan Documents. The Administrative Agent shall not
have, by reason of this Agreement or any other Loan Document, a fiduciary
relationship in respect of any Lender; and nothing in this Agreement or any
other Loan Document, express or implied, is intended to or shall be so
construed as to impose upon the Administrative Agent any obligations or
liabilities in respect of this Agreement or any other Loan Document except as
expressly set forth herein or therein. The Administrative Agent may execute any
of its duties under this Agreement or any other Loan Document by or through
agents or attorneys-in-fact and shall not be responsible for the negligence or
misconduct of any agents or attorneys-in-fact that it selects with reasonable
care. The Administrative Agent shall be entitled to consult with legal counsel,
independent public accountants and other experts selected by it with respect to
all matters pertaining to this Agreement and the other Loan Documents and its
duties hereunder and thereunder and shall not be liable for any action taken or
omitted to be taken in good faith by it in accordance with the advice of such
counsel, accountants or experts. The Lenders hereby acknowledge that the
Administrative Agent shall not be under any duty to take any discretionary
action permitted to be taken by it pursuant to the provisions of this Agreement
or any other Loan Document unless it shall be requested in writing to do so by
the Required Lenders (or, where a higher percentage of the Lenders is expressly
required hereunder, such Lenders).

         SECTION 11.3 Exculpatory Provisions. Neither the Administrative Agent
nor any of its officers, directors, employees, agents, attorneys-in-fact or
Affiliates shall be (i) liable for any action taken or omitted to be taken by
it or such Person under or in connection with the Loan Documents, except for
its or such Person's own gross negligence or willful misconduct, (ii)
responsible in any manner to any Lender for any recitals, statements,
information, representations or warranties herein or in any other Loan Document
or in any document, instrument, certificate, report or other writing delivered
in connection herewith or therewith, for the execution, effectiveness,
genuineness, validity, enforceability or sufficiency of this Agreement or any
other Loan Document, or for the financial condition of Borrowers or any of
their Subsidiaries or any other Person, or (iii) required to ascertain or make
any inquiry concerning the performance or observance of any of the terms,
provisions or conditions of this Agreement or any other Loan Document or the
existence or possible existence of


                                      -85-
<PAGE>   92


any Default or Event of Default, or to inspect the properties, books or records
of the Borrowers or any of their Subsidiaries.

         SECTION 11.4 Reliance by Administrative Agent. The Administrative
Agent shall be entitled to rely, and shall be fully protected in relying, upon
any notice, statement, consent or other communication (including, without
limitation, any thereof by telephone, telecopy, telex, telegram or cable)
believed by it in good faith to be genuine and correct and to have been signed,
sent or made by the proper Person or Persons. The Administrative Agent may deem
and treat each Lender as the owner of its interest hereunder for all purposes
hereof unless and until a written notice of the assignment, negotiation or
transfer thereof shall have been given to the Administrative Agent in
accordance with the provisions of this Agreement. The Administrative Agent
shall be entitled to refrain from taking or omitting to take any action in
connection with this Agreement or any other Loan Document (i) if such action or
omission would, in the reasonable opinion of the Administrative Agent, violate
any applicable law or any provision of this Agreement or any other Loan
Document or (ii) unless and until it shall have received such advice or
concurrence of the Required Lenders (or, where a higher percentage of the
Lenders is expressly required hereunder, such Lenders) as it deems appropriate
or it shall first have been indemnified to its satisfaction by the Lenders
against any and all liability and expense (other than liability and expense
arising from its own gross negligence or willful misconduct) that may be
incurred by it by reason of taking, continuing to take or omitting to take any
such action. Without limiting the foregoing, no Lender shall have any right of
action whatsoever against the Administrative Agent as a result of the
Administrative Agent's acting or refraining from acting hereunder or under any
other Loan Document in accordance with the instructions of the Required Lenders
(or, where a higher percentage of the Lenders is expressly required hereunder,
such Lenders), and such instructions and any action taken or failure to act
pursuant thereto shall be binding upon all of the Lenders (including all
subsequent Lenders).

         SECTION 11.5 Non-Reliance on Administrative Agent and Other Lenders.
Each Lender expressly acknowledges that neither the Administrative Agent nor
any of its officers, directors, employees, agents, attorneys-in-fact or
Affiliates has made any representation or warranty to it and that no act by the
Administrative Agent or any such Person hereafter taken, including any review
of the affairs of AHL and its Subsidiaries, shall be deemed to constitute any
representation or warranty by the Administrative Agent to any Lender. Each
Lender represents to the Administrative Agent that (i) it has, independently
and without reliance upon the Administrative Agent or any other Lender and
based on such documents and information as it has deemed appropriate, made its
own appraisal of and investigation into the business, prospects, operations,
properties, financial and other condition and creditworthiness of AHL and its
Subsidiaries and made its own decision to enter into this Agreement and extend
credit to the Borrowers hereunder, and (ii) 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 credit analysis, appraisals and decisions in taking or not taking
action hereunder and under the other Loan Documents and to make such
investigation as it deems necessary to inform itself as to the business,
prospects, operations, properties, financial and other condition and
creditworthiness of AHL and its Subsidiaries. Except as expressly provided in
this Agreement and the other Loan Documents, the Administrative Agent shall
have no duty or responsibility, either initially or on a continuing basis, to
provide any Lender with any credit or other information concerning the
business, prospects,


                                      -86-
<PAGE>   93


operations, properties, financial or other condition or creditworthiness of AHL
or its Subsidiaries or any other Person that may at any time come into the
possession of the Administrative Agent or any of its officers, directors,
employees, agents, attorneys-in-fact or Affiliates.

         SECTION 11.6 Notice of Default. The Administrative Agent shall not be
deemed to have knowledge or notice of the occurrence of any Default or Event of
Default unless the Administrative Agent shall have received written notice from
Borrowers or a Lender referring to this Agreement, describing 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, the Administrative
Agent will give notice thereof to the Lenders as soon as reasonably
practicable; provided, however, that if any such notice has also been furnished
to the Lenders, the Administrative Agent shall have no obligation to notify the
Lenders with respect thereto. The Administrative Agent shall (subject to
Sections 11.4 and 12.10) take such action with respect to such Default or Event
of Default as shall reasonably be directed by the Required Lenders; provided
that, unless and until the Administrative Agent shall have received such
directions, the Administrative Agent may (but shall not be obligated to) 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 interests of the
Lenders.

         SECTION 11.7 Indemnification. To the extent the Administrative Agent
is not reimbursed by or on behalf of Borrowers, and without limiting the joint
and several obligations of Borrowers to do so, the Lenders (i) shall and do
hereby indemnify the Administrative Agent and its officers, directors,
employees, agents, attorneys-in-fact and Affiliates, ratably in proportion to
their respective percentages as used in determining the Required Lenders as of
the date of determination, from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses (including, without limitation, attorneys' fees and expenses) or
disbursements of any kind or nature whatsoever that may at any time (including
at any time following the repayment in full of the Loans and the termination of
the Commitments) be imposed on, incurred by or asserted against the
Administrative Agent in any way relating to or arising out of this Agreement or
any other Loan Document or any documents contemplated by or referred to herein
or the transactions contemplated hereby or thereby or any action taken or
omitted by the Administrative Agent under or in connection with any of the
foregoing, and (ii) shall reimburse the Administrative Agent upon demand,
ratably in proportion to their respective percentages as used in determining
the Required Lenders as of the date of determination, for any expenses incurred
by the Administrative Agent in connection with the preparation, negotiation,
execution, delivery, administration, amendment, modification, waiver or
enforcement (whether through negotiations, legal proceedings or otherwise) of,
or legal advice in respect of rights or responsibilities under, this Agreement
or any of the other Loan Documents (including, without limitation, reasonable
attorneys' fees and expenses and compensation of agents and employees paid for
services rendered on behalf of the Lenders); provided, however, that no Lender
shall be liable for any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
to the extent resulting from the gross negligence or willful misconduct of the
party to be indemnified.

         SECTION 11.8 The Administrative Agent in its Individual Capacity. With
respect to its Commitment, the Loans made by it and the Note or Notes issued to
it, the Administrative Agent in its individual capacity and not as
Administrative Agent shall have the same rights and powers under


                                      -87-
<PAGE>   94


the Loan Documents as any other Lender and may exercise the same as though it
were not performing the agency duties specified herein; and the terms
"Lenders," "Required Lenders," "holders of Notes" and any similar terms shall,
unless the context clearly otherwise indicates, include the Administrative
Agent in its individual capacity. The Administrative Agent and its Affiliates
may accept deposits from, lend money to and generally engage in any kind of
banking, trust, financial advisory or other business with the Borrowers, any of
their Subsidiaries or any of their respective Affiliates as if the
Administrative Agent were not performing the agency duties specified herein,
and may accept fees and other consideration from any of them for services in
connection with this Agreement and otherwise without having to account for the
same to the Lenders.

         SECTION 11.9 Successor Administrative Agent. The Administrative Agent
may resign at any time by giving thirty (30) days' prior written notice to the
Borrowers and the Lenders. Upon any such notice of resignation, the Required
Lenders will, with the prior written consent of the Borrowers (which consent
shall not be unreasonably withheld or delayed), appoint from among the Lenders
a successor to the Administrative Agent (provided that the Borrowers' consent
shall not be required in the event a Default or Event of Default shall have
occurred and be continuing). If no successor to the Administrative Agent shall
have been so appointed by the Required Lenders and shall have accepted such
appointment within such thirty-day period, then the retiring Administrative
Agent may, on behalf of the Lenders and after consulting with the Lenders and
the Borrowers, appoint a successor Administrative Agent from among the Lenders.
Upon the acceptance of any appointment as Administrative Agent 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 and under the
other Loan Documents. After any retiring Administrative Agent's resignation as
Administrative Agent, the provisions of this Article XI shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent. If no successor to the Administrative Agent has accepted
appointment as Administrative Agent by the thirtieth (30th) day following a
retiring Administrative Agent's notice of resignation, the retiring
Administrative Agent's resignation shall nevertheless thereupon become
effective, and the Lenders shall thereafter perform all of the duties of the
Administrative Agent hereunder and under the other Loan Documents until such
time, if any, as the Required Lenders appoint a successor Administrative Agent
as provided for hereinabove.

<PAGE>   97


of such rights and obligations. The Borrowers hereby irrevocably consent to the
service of a summons and compliant and other process in any action, claim or

the Notes or the other Loan Documents, any rights or obligations hereunder or
thereunder, or the performance of such rights and obligations, on behalf of

         SECTION 12.5 WAIVER OF JURY TRIAL. TO THE EXTENT PERMITTED BY

IRREVOCABLY WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL WITH RESPECT TO ANY
ACTION, CLAIM OR OTHER PROCEEDING ARISING OUT OF ANY DISPUTE IN CONNECTION WITH
THIS AGREEMENT, THE NOTES OR THE OTHER LOAN DOCUMENTS, ANY RIGHTS OR
OBLIGATIONS HEREUNDER OR THEREUNDER, OR THE PERFORMANCE OF SUCH RIGHTS AND
OBLIGATIONS.

         SECTION 12.6 Reversal of Payment. To the extent any Borrower makes a
payment or payments to the Administrative Agent for the ratable benefit of the
Lenders or the Administrative Agent receives any payment or proceeds of the
Collateral which payments or proceeds or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to a trustee, receiver or any other party under any
bankruptcy law, state or federal law, common law or equitable cause, then, to
the extent of such payment or proceeds repaid, the Obligations or part thereof
intended to be satisfied shall be revived and continued in full force and
effect as if such payment or proceeds had not been received by the
Administrative Agent.

         SECTION 12.7 Successors and Assigns; Participations.

         (a) Assignment by Lenders. Each Lender may assign to one or more other
Eligible Assignees (each, an "Assignee") all or a portion of its rights and
obligations under this Agreement (including, without limitation, all or a
portion of its Commitment, the outstanding Loans made by it and the Note or
Notes held by it); provided, however, that (i) any such assignment (other than
an assignment to a Lender or an Affiliate of a Lender) shall not be made
without the prior written consent of the Administrative Agent and, if no Event
of Default then exists, the Borrowers (to be evidenced by their counter
execution of the relevant Assignment and Acceptance), which consent shall not
be unreasonably withheld, (ii) except in the case of an assignment to a Lender
or an Affiliate of a Lender, the amount of the Commitment of the assigning
Lender being assigned pursuant to each


                                      -91-
<PAGE>   98


such assignment (determined as of the date of the Assignment and Acceptance
with respect to each such assignment) shall in no event be less than the lesser
of (y) the entire Commitment of such Lender immediately prior to such
assignment or (z) $5,000,000, and (iii) the parties to each such assignment
will execute and deliver to the Administrative Agent, for its acceptance and
recording in the Register, an Assignment and Acceptance (an "Assignment and
Acceptance") in the form of Exhibit E attached hereto, together with any Note
or Notes subject to such assignment, and, except in the case of an assignment
to a Lender or an Affiliate of a Lender, will pay a nonrefundable processing
fee of $3,500 to the Administrative Agent for its own account. Upon such
execution, delivery, acceptance and recording of the Assignment and Acceptance,
from and after the effective date specified therein, which effective date shall
be at least five Business Days after the execution thereof (unless the
Administrative Agent shall otherwise agree), (A) the Assignee thereunder shall
be a party hereto and, to the extent that rights and obligations hereunder have
been assigned to it pursuant to such Assignment and Acceptance, shall have the
rights and obligations of the assigning Lender hereunder with respect thereto
and (B) the assigning Lender shall, to the extent that rights and obligations
hereunder have been assigned by it pursuant to such Assignment and Acceptance,
relinquish its rights (other than rights under the provisions of this Agreement
and the other Loan Documents relating to indemnification or payment of fees,
costs and expenses, to the extent such rights relate to the time prior to the
effective date of such Assignment and Acceptance) and be released from its
obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all or the remaining portion of such assigning Lender's
rights and obligations under this Agreement, such Lender shall cease to be a
party hereto). The terms and provisions of each Assignment and Acceptance
shall, upon the effectiveness thereof, be incorporated into and made a part of
this Agreement, and the covenants, agreements and obligations of each Lender
set forth therein shall be deemed made to and for the benefit of the
Administrative Agent and the other parties hereto as if set forth at length
herein.

         (b) Maintenance of the Register. The Administrative Agent will
maintain at its address for notices referred to herein a copy of each
Assignment and Acceptance delivered to and accepted by it and a register for
the recordation of the names and addresses of the Lenders and the Commitments
of, and principal amount of the Loans owing to, each Lender from time to time
(the "Register"). The entries in the Register shall be conclusive and binding
for all purposes, absent manifest error, and the Borrowers, the Administrative
Agent and the Lenders may treat each Person whose name is recorded in the
Register as a Lender hereunder for all purposes of this Agreement. The Register
shall be available for inspection by Borrowers and each Lender at any
reasonable time and from time to time upon reasonable prior notice.

         (c) Acceptance of Assignment; Replacement Notes. Upon its receipt of a
duly completed Assignment and Acceptance executed by an assigning Lender and an
Assignee and counter executed by the Borrowers (if required), together with any
Note or Notes subject to such assignment and the processing fee referred to in
subsection (a) above, the Administrative Agent will (i) accept such Assignment
and Acceptance, (ii) on the effective date thereof, record the information
contained therein in the Register and (iii) give notice thereof to the
Borrowers and the Lenders. Within five (5) Business Days after its receipt of
such notice, the Borrowers, at their own expense, will execute and deliver to
the Administrative Agent in exchange for the surrendered Note or Notes a new
Note or Notes to the order of such Assignee in an aggregate principal amount
equal to the principal amount


                                      -92-
<PAGE>   99


of the Commitment (or, if the Commitments have been terminated, the principal
amount of the Loans) assumed by it pursuant to such Assignment and Acceptance
and, to the extent the assigning Lender has retained its Loans and/or
Commitment hereunder, a new Note or Notes to the order of the assigning Lender
in an aggregate principal amount equal to the principal amount of the
Commitment (or, if the Commitments have been terminated, the principal amount
of the Loans) retained by it hereunder. Such new Note or Notes shall be dated
the date of the replaced Note or Notes and shall otherwise be in substantially
the forms of the Notes attached hereto as Exhibits A-1 and A-2. The
Administrative Agent will return canceled Notes to the Borrowers.

         (d) Participations. Each Lender may, without the consent of the
Borrowers, the Administrative Agent or any other Lender, sell to one or more
other Persons (each, a "Participant") participations in any portion comprising
less than all of its rights and obligations under this Agreement (including,
without limitation, a portion of its Commitment, the outstanding Loans made by
it and the Note or Notes held by it); provided, however, that (i) such Lender's
obligations under this Agreement shall remain unchanged and such Lender shall
remain solely responsible for the performance of such obligations, (ii) any
such participation (other than a participation by Bank Leumi Le-Israel, B.M.,
Miami Agency to its subsidiary Bank Leumi USA) shall be in an amount of not
less than $5,000,000, but no Lender shall sell any participation that, when
taken together with all other participations, if any, sold by such Lender,
covers more than fifty percent of the beneficial interests in all of such
Lender's rights and obligations under this Agreement, (iii) the Borrowers, the
Administrative Agent and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement, and no Lender shall permit any Participant to
have any voting rights or any right to control the vote of such Lender with
respect to any amendment, modification, waiver, consent or other action
hereunder or under any other Loan Document (except as to actions that would (w)
reduce or forgive the principal amount of, or rate of interest (other than
interest accruing as provided in Section 3.1(f)) on, any Loan, or reduce or
forgive any fees or other Obligations, (x) extend any date (including without
limitation, the Revolving Facility Termination Date) fixed for the payment of
any principal of or interest on any Loan, any fees or any other Obligations,
(y) release any material portion of Collateral securing the Obligations (other
than (1) upon termination of the Commitments and payment and satisfaction of
all Obligations (other than any Obligations that survive the termination of
this Agreement pursuant to Section 12.12), (2) Collateral constituting property
being sold or disposed of if Borrowers certify to the Administrative Agent that
the sale or disposition is made in compliance with the provisions of this
Agreement and the Security Documents, upon which certification the
Administrative Agent may conclusively rely in good faith, without further
inquiry, or (3) otherwise in accordance with the terms of this Agreement and
the Security Documents), or (z) increase any Commitment of any Lender), and
(iv) except as expressly set forth in this Agreement, no Participant shall have
any rights under this Agreement or any of the other Loan Documents, each
Participant's rights against the granting Lender in respect of any
participation are to be those set forth in the participation agreement, and all
amounts payable by the Borrowers hereunder shall be determined as if such
Lender had not granted such participation. Each Participant may be entitled,
pursuant to the terms of its participation agreement, to compensation
calculated in accordance with the provisions of Sections 3.7, 3.8, 3.9 and 3.10
and to rights of setoff in accordance with Section 10.4, in each case to the
extent that the Lender from which it purchased its participation would be
entitled to such benefits if the participation had not been made;


                                      -93-
<PAGE>   100


provided that nothing contained herein shall cause the Participant to be deemed
to be a Lender or to otherwise be granted any rights under this Agreement.

         (e) Other Assignments. Nothing in this Agreement shall be construed to
prohibit any Lender from pledging or assigning all or any portion of its rights
and interest hereunder or under any Note to any Federal Reserve Bank as
security for borrowings therefrom; provided, however, that no such pledge or
assignment shall release a Lender from any of its obligations hereunder.

         (f) Disclosure of Information; Confidentiality. The Administrative
Agent and the Lenders shall treat as confidential all non-public information,
including, without limitation, all financial projections, obtained pursuant to
the Loan Documents and shall disclose such information outside their
organizations only as may be deemed appropriate by any of the Administrative
Agent or the Lenders in the exercise of its or their rights under the Loan
Documents or as compelled by judicial or administrative process or by other
requirements of Applicable Law or as requested by regulatory authorities or
pursuant to legal process. The Administrative Agent and any Lender may, in
connection with any assignment, proposed assignment, participation or proposed
participation pursuant to this Section 12.7, disclose to the assignee,
participant, proposed assignee or proposed participant, any information
relating to the Borrowers furnished to the Administrative Agent or such Lender.

         SECTION 12.8 Amendments, Waivers and Consents: Renewal. Except as set
forth below, any term, covenant, agreement or condition of this Agreement or
any of the other Loan Documents may be amended or waived by the Lenders, and
any consent given by the Lenders, if, but only if, such amendment, waiver or
consent is in writing signed by the Required Lenders (or by the Administrative
Agent with the consent of the Required Lenders) and delivered to the
Administrative Agent and, in the case of an amendment, signed by the Borrowers;
provided, that no amendment, waiver or consent shall (a) increase the amount or
extend the time of the obligation of the Lenders to make Loans, provided,
however, that the Required Lenders may at any time, in their sole discretion
(but shall be under no obligation to), approve any increases requested by
Borrowers in the amount of the Aggregate Commitment above Three Hundred
Seventy-Five Million Dollars ($375,000,000) without the approval of any other
Lender or Lenders (but in no event will any Lender's Commitment be increased
without the prior written consent of such Lender) so long as after giving
effect to any such proposed increase no Default or Event of Default has
occurred and shall be continuing, (b) extend the originally scheduled time or
times of payment of the principal of any Loan or the time or times of payment
of interest on any Loan or any fees due hereunder, (c) reduce the rate of
interest or fees payable on any Loan (other than interest accruing as provided
in Section 3.1(f)), (d) permit any subordination of the principal or interest
on any Loan to any other Debt, (e) release any material portion of the
Collateral or Security Document (other than (i) upon termination of the
Commitments and payment and satisfaction of all Obligations (other than any
Obligations that survive the termination of this Agreement pursuant to Section
12.12), (ii) Collateral constituting property being sold or disposed of if
Borrowers certify to the Administrative Agent that the sale or disposition is
made in compliance with the provisions of this Agreement and the Security
Documents, upon which certification the Administrative Agent may conclusively
rely in good faith, without further inquiry, or (iii) as specifically permitted
in this Agreement or the applicable Security Document), (f) amend the
provisions of this Section 12.8 or the definition of Required Lenders, (g)
amend the provisions


                                      -94-
<PAGE>   101


of Section 3.5, (h) change the provisions of Section 2.4(f) so that the
percentage of the Commitments allocated to each Lender is changed upon a
reduction of the Commitments, or (i) amend the definition of Alternative
Currency, in each case, without the prior written consent of each Lender. In
addition, no amendment, waiver or consent to the provisions of Article XI shall
be made without the written consent of the Administrative Agent.

         SECTION 12.9 Performance of Duties. The Borrowers' obligations under
this Agreement and each of the Loan Documents shall be performed at the joint
and several sole cost and expense of the Borrowers.

         SECTION 12.10 Indemnification. The Borrowers agree to reimburse the
Administrative Agent and the Lenders for all reasonable costs and expenses,
including reasonable counsel, appraisal, or other expert or consultant fees and
disbursements incurred, and the Borrowers hereby indemnify and hold the
Administrative Agent and the Lenders harmless from and against all losses
suffered by the Administrative Agent and the Lenders in connection with (a) the
exercise by the Administrative Agent or the Lenders of any right or remedy
granted to them under this Agreement or any of the other Loan Documents, (b)
any claim, and the prosecution or defense thereof, arising out of or in any way
connected with this Agreement or any of the other Loan Documents and (c) the
collection or enforcement of the Obligations or any of them; provided, that the
indemnity contained herein shall not apply to the extent that such losses,
claims, damages, liabilities or other expenses result from the gross negligence
or willful misconduct of such indemnified person.

         SECTION 12.11 All Powers Coupled with Interest. All powers of attorney
and other authorizations granted to the Lenders, the Administrative Agent and
any Persons designated by the Administrative Agent or such Lenders pursuant to
any provisions of this Agreement or any of the other Loan Documents shall be
deemed coupled with an interest and shall be irrevocable so long as any of the
Obligations remain unpaid or unsatisfied or the Credit Facilities have not been
terminated.

         SECTION 12.12 Survival of Indemnities. Notwithstanding any termination
of this Agreement, the indemnities to which the Administrative Agent and the
Lenders are entitled under the provisions of this Article XII and any other
provision of this Agreement and the Loan Documents shall continue in full force
and effect and shall protect the Administrative Agent and the Lenders against
events arising after such termination as well as before.

         SECTION 12.13 Provision of Loan Documents. Upon request by AHL, the
Administrative Agent shall use its best efforts to provide to AHL, or to cause
to be provided to AHL, a copy of the final forms of this Agreement and the
other Loan Documents on a diskette or other machine readable format.

neither limit nor amplify the provisions of this Agreement.

         SECTION 12.15 Severability of Provisions. Any provision of this
Agreement or any other Loan Document which is prohibited or unenforceable in
any jurisdiction shall, as to such jurisdiction,


                                      -95-

be ineffective only to the extent of such prohibition or unenforceability
without invalidating the remainder of such provision or the remaining
provisions hereof or thereof or affecting the validity or enforceability of
such provision in any other jurisdiction.

         SECTION 12.16 Counterparts. This Agreement may be executed in any
number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and shall be binding upon all parties, their successors and assigns, and all of
which taken together shall constitute one and the same agreement.

         SECTION 12.17 AHL as Agent for Other Borrowers. Each Borrower hereby
irrevocably appoints and authorizes AHL to be its agent to transact all matters
relating to this Agreement and the other Loan Documents, including, without
limitation, (a) to provide the Administrative Agent with all notices with
respect to Loans for the benefit of any other Borrower and all other notices
and instructions under this Agreement and (b) to take, on behalf of Borrowers,
all actions, including, without limitation, the provision of consents, as are
required or permitted to be taken by any or all of the Borrowers pursuant to
this Agreement.

         SECTION 12.18 Term of Agreement. This Agreement shall remain in effect
from the Closing Date through and including the date upon which all Obligations
shall have been paid and satisfied in full (other than any Obligations that
survive the termination of this Agreement pursuant to Section 12.12) and the
Commitments have been terminated. No termination of this Agreement shall affect
the rights and obligations of the parties hereto arising prior to such
termination.

         SECTION 12.19 EMU; Continuity of Contract, Etc.

         (a) Definitions. As used in this Section 12.19 the following terms
have the following meanings:

         "beginning of the third stage of EMU" means the date the third stage
         of EMU began or the date on which circumstances arise which, in the
         opinion of the Administrative Agent, have substantially the same
         effect and result in substantially the same consequences as the
         beginning of the third stage of EMU as contemplated by the Treaty on
         European Union.

         "EMU" means economic and monetary union as contemplated in the Treaty
         on European Union.

         "EMU legislation" means legislative measures of the European Council
         for the introduction of change over to or operation of a single or
         unified European currency (whether known as the euro or otherwise),
         being in part the implementation of the third stage of EMU.

         "euro" means the single currency to which participating member states
         of the European Union have converted and may from time to time in the
         future convert.

         "euro unit" means the currency unit of the euro.

<PAGE>   103


         "fixed exchange rate" means the exchange rate for a national currency
         unit into a euro unit set in accordance with EMU legislation in effect
         from time to time.

         "national currency unit" means the unit of currency (other than a euro
         unit) of a participating member state.

         "participating member state" means each state so described in any EMU
         legislation that converts from its national currency unit to the euro.

         "Treaty on European Union" means the treaty of Rome of March 25, 1957,
         as amended by the Single European Act 1986 and the Maastricht Treaty
         (signed February 7, 1992), as amended from time to time.

         (b) Effectiveness of Provisions. The provisions of clauses (c) through
(m) below, inclusive, shall be effective at and from the later of the execution
of this Agreement or the beginning of the third stage of EMU, provided, that if
and to the extent that any such provision relates to any state (or the currency
of such state) that is not a participating member state on the beginning of the
third stage of EMU, such provision shall become effective in relation to such
state (and the currency of such state) at and from the date on which such state
becomes a participating member state.

         (c) Continuity of Contract. The parties to this Agreement agree that
the occurrence or non-occurrence of EMU, any event or events associated with
the EMU and/or the introduction of the euro in all or any part of the European
Union will not result in the discharge, cancellation, rescission or termination
in whole or in part of this Agreement or any other Loan Document or give the
Administrative Agent, the Lenders or the Borrowers the right to cancel,
rescind, terminate or vary this Agreement or any other Loan Document, other
than as specifically provided in this Agreement.

         (d) Redenomination and Alternative Currencies. Each obligation of any
party under this Agreement which has been denominated in the national currency
unit of a participating member state shall be redenominated into the euro unit
at the fixed exchange rate, provided, that if and to the extent that any EMU
legislation provides that following the beginning of the third stage of EMU an
amount denominated either in the euro unit or in the national currency unit of
a member state and payable within the member state by crediting an account of a
creditor can be paid by a debtor either in the euro unit or in that national
currency unit, each party to this Agreement shall be entitled to pay or repay
any such amount either in the euro unit or in such national currency unit;
provided, however, any amount paid in a national currency unit shall equal, at
the fixed exchange rate for that national currency unit, the required amount
stated to be due in euro units.

         (e) Loans. Any Loan in the currency of a participating member state
shall be made in the euro unit, provided that any Loan may, if so requested by
any Borrower, be made in the national currency unit (based upon the published
fixed exchange rate) of any participating member state so long as such national
currency unit continues to be available as legal tender for obligations of the
same type or character as the obligations set forth in this Agreement, is
freely convertible and is not subject to exchange controls.

         (f) Business Days. With respect to any amount denominated or to be
denominated in the euro unit or a national currency unit, any reference to a
"Business Day" shall be construed as a reference to a day (other than a
Saturday or Sunday) on which banks are generally open for business in New York
City and prime banks in London generally provide quotations for deposits
denominated in the euro unit and such national currency unit.

         (g) Payments to the Administrative Agent. Those Sections of this
Agreement providing for payment or repayment in a national currency unit shall
be construed so that, in relation to the payment of any amount of euro units or
national currency units, such amount shall be made available to the
Administrative Agent in immediately available, freely transferable, cleared
funds to such account with each bank (in such principal financial center) as
the Administrative Agent may from time to time nominate for this purpose.

         (h) Payment by the Administrative Agent to the Lenders. Any amount
payable by the Administrative Agent to the Lenders under this Agreement in the
national currency unit of a participating member state shall be paid in the
currency received by it from the Borrowers.

         (i) Payments by the Administrative Agent or Lenders Generally. With
respect to the payment of any amount denominated in the euro unit or in a
national currency unit, the Administrative Agent shall not be liable to the
Borrowers or any of the Lenders, nor shall any Lender be liable to the Borrower
or the Administrative Agent, in any way whatsoever for any delay, or the
consequences of any delay, in the crediting to any account of any amount
required by this Agreement to be paid by the Administrative Agent or such
Lender, as the case may be, if the Administrative Agent or such Lender, as the
case may be, has made reasonable effort to effect all relevant steps to
achieve, on the date required by the Agreement, the payment of such amount in
immediately available, freely transferable, cleared funds (in the euro unit or,
as the case may be, in a national currency unit) to the account with the bank
in the principal financial center in the participating member state which the
Borrowers or, as the case may be, the Administrative Agent or any Lender shall
have specified for such purpose. In this paragraph, "all relevant steps" means
all such steps as may be prescribed from time to time by the regulations or
operating procedures of such clearing or settlement system as the
Administrative Agent or any Lender, as the case may be, may from time to time
reasonably believe to be in effect for the purpose of clearing or settling
payment of the euro.

         (j) Basis of Accrual. If the basis of accrual of interest or fees
expressed in this Agreement with respect to the currency of any state that
becomes a participating member state, in Administrative Agent's judgment, shall
not be available because interest rate quotes for a national currency unit are
no longer provided, or shall be inconsistent with any convention or practice in
the London Interbank Market for the basis of accrual of interest or fees in
respect of the euro, such convention or practice shall replace such expressed
basis effective as of and from the date on which such state becomes a
participating member state; provided, however, if any Loan in the currency of
such state is outstanding immediately prior to such date, such replacement
shall take effect, with respect to such Loan, at the end of the then current
Interest Period.

         (k) Rounding and Other Consequential Changes. Without prejudice and in
addition to any method of conversion or rounding prescribed by any EMU
legislation and without prejudice to


                                      -98-
<PAGE>   105


the respective liabilities for indebtedness of the Borrowers to the
Administrative Agent and to the Lenders and the Administrative Agent and the
Lenders to the Borrowers under or pursuant to this Agreement:

                  (i) each reference in this Agreement to a minimum amount (or
         an integral multiple thereof) in a national currency unit to be paid
         to or by the Administrative Agent or Lenders shall be replaced by a
         reference to such reasonably comparable amount (or an integral
         multiple thereof) in the euro unit as the Administrative Agent may
         from time to time specify; and

                  (ii) except as expressly provided in this Agreement, each
         provision of this Agreement, including, without limitation, the right
         to combine currencies to effect a set off, shall be subject to such
         reasonable changes of interpretation as the Administrative Agent may
         from time to time specify to be necessary or appropriate to reflect
         the implementation of the EMU to place the parties hereto in
         substantially the position they would have occupied had the EMU not
         been implemented.

         (l) Exchange Indemnification and Increased Costs. The Borrowers shall
upon demand from the Administrative Agent, pay to the Administrative Agent for
the account of each Lender the amount of (i) any loss or cost or increased cost
incurred by the Administrative Agent or such Lender in respect of any Loans
made hereunder as a result of the Borrowers' election to borrow in national
currency units and repay in euro units or to borrow in euro units and repay in
national currency units, (ii) any reduction in any amount payable to, or in the
effective return on its capital to, the Administrative Agent or such Lender in
respect of any Loans made hereunder as a result of the Borrowers' election to
borrow in national currency units and repay in euro units or to borrow in euro
units and repay in national currency units, (iii) any interest or other return
in respect of any Loans made hereunder, including principal, foregone by the
Administrative Agent or its holding company or any Lender or its holding
company, as a result of the introduction of, change over to or operation of the
euro in any participating member state, or (iv) any currency exchange loss that
the Administrative Agent or such Lender sustains in respect of any Loans made
hereunder as a result of the Borrowers' election to borrow in national currency
units and repay in euro units or to borrow in euro units and repay in national
currency units.

         (m) Further Assurance. Each Borrower agrees, at the request of the
Administrative Agent, at the time of or at any time following the
implementation of the EMU, to enter into an agreement amending this Agreement
in such manner as the Administrative Agent reasonably shall request in order to
reflect the conversion of a participating member state's national currency unit
into the euro unit and to place the parties hereto in the position they would
have been in had the EMU not been implemented.

         SECTION 12.20 Entire Agreement. This Agreement and the other Loan
Documents referred to herein embody the final, entire agreement among the
parties hereto and supersede any and all prior commitments, agreements,
representations, and understandings, whether written or oral, relating to the
subject matter hereof and may not be contradicted or varied by evidence of

contemporaneous, or subsequent oral agreements or discussions of the parties
hereto. There are no oral agreements among the parties hereto.

         SECTION 12.21 Transitional Provisions.

                  (a) Prior Credit Agreement Superseded. This Agreement shall
on the Closing Date supersede the Prior Credit Agreement in its entirety,
except as provided in this Section 12.21. On the Closing Date, (i) the rights
and obligations of the parties evidenced by the Prior Credit Agreement shall be
evidenced by this Credit Agreement and the other Loan Documents, (ii) the

Closing Date shall be paid to the Administrative Agent on the Closing Date for
allocation among the Existing Lenders in accordance with the terms of the Prior
Credit Agreement, (iv) all "Swingline Loans" as defined in the Prior Credit
Agreement (the "Existing Swingline Loans") shall be continued as Swingline

the Swingline Lender in accordance with the terms of the Prior Credit
Agreement, (v) all "European Swingline Loans" as defined in the Prior Credit
Agreement (the "Existing European Swingline Loans") shall be continued as

Loans through (but not including) the Closing Date shall be paid to the
Administrative Agent for the account of the European Swingline Lender in
accordance with the terms of the Prior Credit Agreement, (vi) all Existing
Letters of Credit shall, for purposes of this Credit Agreement, be Letters of

case of any fractional periods), and shall be paid on the Closing Date to the
Administrative Agent for the account of the Administrative Agent, the Issuing
Bank and the Existing Lenders in accordance with the terms of the Prior Credit
Agreement.

                  (b) Return of Notes. As soon as reasonably practicable after
its receipt, on the Closing Date, of its Notes hereunder and payment in full of
any "Obligations" owed to it under the Prior Credit Agreement (some or all of
which may be paid with the proceeds of Loans made in accordance with the terms
and conditions hereof), each of the Lenders that was, immediately prior to the
Closing Date, a party to the Prior Credit Agreement will promptly return to AHL
any promissory notes of the Borrowers that may be held by such Lender pursuant
to the Prior Credit Agreement. In addition, the Administrative Agent will
request that any "Lender" under the Prior Credit Agreement which is not a
Lender hereunder promptly return to AHL any promissory notes of the Borrowers
held by such Person pursuant to the Prior Credit Agreement upon receipt by it
of payment of all "Obligations" owed to it under the Prior Credit Agreement.
