letters of credit (each a "Letter of Credit") up to a maximum aggregate
Stated Amount at any one time outstanding not to exceed the L/C Commitment
Amount.

     (b)  Terms of Letters of Credit.  At the time of issuance, the amount,
form, terms and conditions of each Letter of Credit, and of any drafts or
acceptances thereunder, shall be subject to approval by the Agent and the
Borrower.  Notwithstanding the foregoing, in no event may the expiration date

the Agent shall issue the requested Letter of Credit on the requested date of
issuance.  Upon the written request of the Borrower, the Agent shall deliver

time after the date of issuance thereof.  To the extent any term of a Letter
of Credit Document is inconsistent with a term of any Credit Document, the
term of such Credit Document shall control.

     (d)  Reimbursement Obligations.  Upon receipt by the Agent from the
beneficiary of a Letter of Credit of any demand for payment under such Letter
of Credit, the Agent shall promptly notify the Borrower of the amount to be
paid by the Agent as a result of such demand and the date on which payment is
to be made by the Agent to such beneficiary in respect of such demand.  The
Borrower hereby unconditionally and irrevocably agrees to pay and reimburse
the Agent for the amount of each demand for payment under such Letter of
Credit on or prior to the date on which payment is to be made by the Agent to
the beneficiary thereunder, without presentment, demand, protest or other
formalities of any kind.  Upon receipt by the Agent of any payment in respect
of any Reimbursement Obligation, the Agent shall promptly pay to each Lender

Agent whether or not the Borrower intends to borrow hereunder to finance its
obligation to reimburse the Agent for the amount of the related demand for
payment and, if it does, the Borrower shall submit a timely Notice of
Borrowing or Notice of Swingline Borrowing, as appropriate.  If the Borrower
fails to so advise the Agent, or if the Borrower fails to reimburse the Agent
for a demand for payment under a Letter of Credit by the date of such
payment, then (i) if the applicable conditions contained in Article V. would
permit the making of Revolving Loans, the Borrower shall be deemed to have
requested a borrowing of Revolving Loans (which shall be Base Rate Loans) in
an amount equal to the unpaid Reimbursement Obligation and the Agent shall
give each Lender prompt notice of the amount of the Revolving Loan (which
shall not be subject to the limitations of Section 3.5.) to be made by such
Lender, the proceeds of which such Lender shall make available to the Agent
not later than 1:00 p.m. and (ii) if such conditions would not permit the
making of Revolving Loans, the provisions of subsection (j) of this Section
shall apply.

     (f)  Effect of Letters of Credit on Commitments.  Upon the issuance by
the Agent of any Letter of Credit and until such Letter of Credit shall have
expired or been terminated, the Commitment of each Lender shall be deemed to
be utilized for all purposes of this Agreement in an amount equal to such
Lender's Commitment Percentage of the Stated Amount of such Letter of Credit
plus any related Reimbursement Obligations then outstanding.

     (g)  Agent's Duties Regarding Letters of Credit; Unconditional Nature of
Reimbursement Obligation.  In examining documents presented in connection
with drawings under Letters of Credit and making payments under such Letters
of Credit against such documents, the Agent shall use the same standard of
care as it uses in connection with examining documents presented in
connection with drawings under letters of credit in which it has not sold
participations and making payments under such letters of credit.  The
Borrower assumes all risks of the acts and omissions of, or misuse of the
Letters of Credit by, the respective beneficiaries of such Letters of Credit.
In furtherance and not in limitation of the foregoing, neither the Agent nor
any of the Lenders shall be responsible for (i) the form, validity,
sufficiency, accuracy, genuineness or legal effects of any document submitted
by any party in connection with the application for and issuance of or any
drawing honored under any Letter of Credit even if it should in fact prove to
be in any or all respects invalid, insufficient, inaccurate, fraudulent or
forged; (ii) 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, which
may prove to be invalid or ineffective for any reason; (iii) failure of the
beneficiary of any Letter of Credit to comply fully with conditions required
in order to draw upon such Letter of Credit; (iv) errors, omissions,
interruptions or delays in transmission or delivery of any messages, by mail,
cable, telex, telecopy or otherwise, whether or not they be in cipher absent
gross negligence or willful misconduct by the Agent or except to the extent
found in a final, non-appealable judgment by a court of competent
jurisdiction or by a binding determination of any arbitral body, as
applicable, to have resulted from the bad faith of the Agent; (v) errors in
interpretation of technical terms absent gross negligence or willful
misconduct by the Agent or except to the extent found in a final, non-
appealable judgment by a court of competent jurisdiction or by a binding
determination of any arbitral body, as applicable, to have resulted from the
bad faith of the Agent; (vi) any loss or delay in the transmission or
otherwise of any document required in order to make a drawing under any
Letter of Credit, or of the proceeds thereof; (vii) the misapplication by the
beneficiary of any such Letter of Credit, or the proceeds of any drawing
under such Letter of Credit; or (viii) any consequences arising from causes
beyond the control of the Agent or the Lenders.  None of the above shall
affect, impair or prevent the vesting of any of the Agent's rights or powers
hereunder.  Any action taken or omitted to be taken by the Agent under or in
connection with any Letter of Credit, if taken or omitted in the absence of
gross negligence or willful misconduct, shall not create against the Agent
any liability to the Borrower or any Lender; provided, however, nothing
contained in this subsection shall be deemed to constitute a waiver of any
remedy the Borrower may have against the Agent or any Lender to the extent
resulting from the gross negligence or willful misconduct of the Agent or
such Lender, as the case may be, or to the extent resulting from the bad
faith of the Agent or a Lender, as the case may be, as determined in a final,
non-appealable judgment by a court of competent jurisdiction or by binding
arbitration, as applicable.  In this connection, the obligation of the
Borrower to reimburse the Agent for any drawing made under any Letter of
Credit shall be absolute, unconditional and irrevocable and shall be paid
strictly in accordance with the terms of this Agreement under all
circumstances whatsoever, including without limitation, the following
circumstances: (A) any lack of validity or enforceability of any Letter of
Credit Document or any term or provisions therein; (B) any amendment or
waiver of or any consent to departure from all or any of the Letter of Credit
Documents; (C) the existence of any claim, setoff, defense or other right
which the Borrower may have at any time against the Agent, any Lender, any
beneficiary of a Letter of Credit or any other Person, whether in connection
with this Agreement, the transactions contemplated hereby or in the Letter of
Credit Documents or any unrelated transaction; (D) any breach of contract or
dispute between the Borrower, the Agent, any Lender or any other Person;
(E) any demand, statement or any other document presented under a Letter of
Credit proving to be forged, fraudulent, invalid or insufficient in any
respect or any statement therein or made in connection therewith being untrue
or inaccurate in any respect whatsoever; (F) any non-application or
misapplication by the beneficiary of a Letter of Credit of the proceeds of
any drawing under such Letter of Credit; (G) payment by the Agent under the
Letter of Credit against presentation of a draft or certificate which does
not strictly comply with the terms of the Letter of Credit; and (H) any other
act, omission to act, delay or circumstance whatsoever that might, but for
the provisions of this Section, constitute a legal or equitable defense to or
discharge of the Borrower's Reimbursement Obligations.  Nothing herein
provides a waiver of any remedies the Borrower may have for (i) the Agent's
or any Lender's gross negligence or willful misconduct or (ii) actions taken
(or not taken) by the Agent or the Lenders to the extent found in a final,
non-appealable judgment by a court of competent jurisdiction or by a binding
determination of any arbitral body, as applicable, to have been taken (or not
taken) in bad faith.

     (h)  Amendments, Etc.  The issuance by the Agent of any amendment,
supplement or other modification to any Letter of Credit shall be subject to
the same conditions applicable under this Agreement to the issuance of new
Letters of Credit (including, without limitation, that the request therefor
be made through the Agent), and no such amendment, supplement or other
modification shall be issued unless either (i) the respective Letter of
Credit affected thereby would have complied with such conditions had it
originally been issued hereunder in such amended, supplemented or modified
form or (ii) the Requisite Lenders shall have consented thereto.

     (i)  Lenders' Participation in Letters of Credit.  Immediately upon the
issuance by the Agent of any Letter of Credit each Lender shall be deemed to
have irrevocably and unconditionally purchased and received from the Agent,
without recourse or warranty, an undivided interest and participation to the
extent of such Lender's Commitment Percentage of the liability of the Agent
with respect to such Letter of Credit and each Lender thereby shall
absolutely, unconditionally and irrevocably assume, as primary obligor and
not as surety, and shall be unconditionally obligated to the Agent to pay and
discharge when due, such Lender's Commitment Percentage of the Agent's
liability under such Letter of Credit.  In addition, upon the making of each
payment by a Lender to the Agent in respect of any Letter of Credit pursuant
to the immediately following subsection (j), such Lender shall, automatically
and without any further action on the part of the Agent or such Lender,
acquire (i) a participation in an amount equal to such payment in the
Reimbursement Obligation owing to the Agent by the Borrower in respect of
such Letter of Credit and (ii) a participation in a percentage equal to such
Lender's Commitment Percentage in any interest or other amounts payable by
the Borrower in respect of such Reimbursement Obligation (other than the Fees
payable to the Agent pursuant to the last sentence of Section 3.6.(b)).

     (j)  Payment Obligation of Lenders.  Each Lender severally agrees to pay
to the Agent on demand in immediately available funds in Dollars the amount
of such Lender's Commitment Percentage of each drawing paid by the Agent
under each Letter of Credit to the extent such amount is not reimbursed by
the Borrower pursuant to Section 2.2.(d) and is not available from funds then
on deposit in the Collateral Account.  Each such Lender's obligation to make
such payments to the Agent under this subsection, and the Agent's right to
receive the same, shall be absolute, irrevocable and unconditional and shall
not be affected in any way by any circumstance whatsoever, including without
limitation, (i) the failure of any other Lender to make its payment under
this subsection, (ii) the financial condition of the Borrower or any other
Loan Party, (iii) the existence of any Default or Event of Default, including
any Event of Default described in Section 10.1.(e) or 10.1.(f) or (iv) the
termination of the Commitments.  Each such payment to the Agent shall be made
without any offset, abatement, withholding or deduction whatsoever.

     (k)  Information to Lenders.  Upon the request of any Lender from time
to time, the Agent shall deliver to such Lender any information reasonably
requested by such Lender with respect to each Letter of Credit then
outstanding.  Other than as set forth in this subsection, the Agent shall
have no duty to notify the Lenders regarding the issuance or other matters
regarding Letters of Credit issued hereunder.  The failure of the Agent to
perform its requirements under this subsection shall not relieve any Lender
from its obligations under Section 2.2.(j).

    Section 2.3.  Rates and Payment of Interest on Revolving Loans.

     (a)  Rates.  The Borrower promises to pay to the Agent for the account
of each Lender interest on the unpaid principal amount of each Revolving Loan
made by such Lender for the period from and including the date of the making
of such Revolving Loan to but excluding the date such Revolving Loan shall be
paid in full, at the following per annum rates:

             (i)  during such periods as such Revolving Loan is a Base Rate
      Loan, at the Base Rate (as in effect from time to time), plus the
      Applicable Margin; and

            (ii)  during such periods as such Revolving Loan is a LIBOR Loan,
      at the Adjusted Eurodollar Rate for such Loan for the Interest Period
      therefor, plus the Applicable Margin.

Notwithstanding the foregoing, during the continuance of an Event of Default,
the Borrower shall pay to the Agent for the account of each Lender interest
at the Post-Default Rate on the outstanding principal amount of any Loan made
by such Lender, on all Reimbursement Obligations and on any other amount
payable by the Borrower hereunder or under the Notes held by such Lender to
or for the account of such Lender (including without limitation, accrued but
unpaid interest to the extent permitted under Applicable Law).

     (b)  Payment of Interest.  Accrued interest on each Loan shall be
payable (i) in the case of a Base Rate Loan, monthly in arrears on the last
Business Day of each calendar month, (ii) in the case of a LIBOR Loan, on the
last day of each Interest Period therefor and, if such Interest Period is
longer than three months, at three-month intervals following the first day of
such Interest Period, and (iii) in the case of any Loan, upon the payment,
prepayment or Continuation thereof or the Conversion of such Loan to a Loan
of another Type (but only on the principal amount so paid, prepaid or
Converted).  Interest payable at the Post-Default Rate shall be payable from
time to time on demand.  Promptly after the determination of any interest
rate provided for herein or any change therein, the Agent shall give notice
thereof to the Lenders to which such interest is payable and to the Borrower.
All determinations by the Agent of an interest rate hereunder shall be
conclusive and binding on the Lenders and the Borrower for all purposes,
absent manifest error.

Section 2.4.  Number of Interest Periods.

     There may be no more than 6 different Interest Periods outstanding at
the same time.

Section 2.5.  Repayment of Loans.

     The Borrower shall repay the entire outstanding principal amount of, and
all accrued but unpaid interest on, the Loans on the Termination Date.

Section 2.6.  Prepayments.

     (a)  Optional.  Subject to Section 4.4, the Borrower may prepay any Loan
at any time without premium or penalty.  The Borrower shall give the Agent
notice of the prepayment of any Revolving Loan in writing (or by telephone
promptly confirmed in writing) no later than 11:30 a.m. (a) in the case of
the prepayment of any LIBOR Loans, on the date 3 Business Days prior to the
proposed date of repayment and (b) in the case of the prepayment of Base Rate
Loans, on the date of such prepayment.

     (b)  Mandatory.  If at any time the aggregate principal amount of all
outstanding Revolving Loans, together with the aggregate amount of all Letter
of Credit Liabilities and the aggregate principal amount of all outstanding
Swingline Loans, exceeds the aggregate amount of the Commitments in effect at
such time, the Borrower shall immediately pay to the Agent for the accounts
of the Lenders the amount of such excess.  Such payment shall be applied to
pay all amounts of principal outstanding on the Loans and any Reimbursement
Obligations pro rata in accordance with Section 3.2. and the remainder, if
any, shall be deposited into the Collateral Account for application to any
Reimbursement Obligations.  If the Borrower is required to pay any
outstanding LIBOR Loans by reason of this Section prior to the end of the
applicable Interest Period therefor, the Borrower shall pay all amounts due
under Section 4.4.

Section 2.7.  Continuation.

     So long as no Default or Event of Default shall have occurred and be
continuing, the Borrower may on any Business Day, with respect to any LIBOR
Loan, elect to maintain such LIBOR Loan or any portion thereof as a LIBOR
Loan by selecting a new Interest Period for such LIBOR Loan.  Each new
Interest Period selected under this Section shall commence on the last day of
the immediately preceding Interest Period.  Each selection of a new Interest
Period shall be made by the Borrower giving to the Agent a Notice of
Continuation not later than 11:00 a.m. on the third Business Day prior to the
date of any such Continuation.  Such notice by the Borrower of a Continuation
shall be in writing and in the form of a Notice of Continuation, specifying
(a) the proposed date of such Continuation, (b) the LIBOR Loan and portion
thereof subject to such Continuation and (c) the duration of the selected
Interest Period, all of which shall be specified in such manner as is
necessary to comply with all limitations on Loans outstanding hereunder.
Each Notice of Continuation shall be irrevocable by and binding on the
Borrower once given.  Promptly after receipt of a Notice of Continuation, the
Agent shall notify each Lender of the proposed Continuation.  If the Borrower
shall fail to select in a timely manner a new Interest Period for any LIBOR
Loan in accordance with this Section, such Loan will automatically, on the
last day of the current Interest Period therefor, Convert into a Base Rate
Loan notwithstanding failure of the Borrower to comply with Section 2.8.

Section 2.8.  Conversion.

     So long as no Default or Event of Default shall have occurred and be
continuing, the Borrower may on any Business Day, upon the Borrower's giving
of a Notice of Conversion to the Agent, Convert all or a portion of a Loan of
one Type into a Loan of another Type.  Any Conversion of a LIBOR Loan into a
Base Rate Loan shall be made on, and only on, the last day of an Interest
Period for such LIBOR Loan and, upon Conversion of a Base Rate Loan into a
LIBOR Loan, the Borrower shall pay accrued interest to the date of Conversion
on the principal amount so Converted.  Each such Notice of Conversion shall
be given not later than 11:00 a.m. on the date of any proposed Conversion
into Base Rate Loans and on the third Business Day prior to the date of any
proposed Conversion into LIBOR Loans.  Promptly after receipt of a Notice of
Conversion, the Agent shall notify each Lender of the proposed Conversion.
Subject to the restrictions specified above, each Notice of Conversion shall
be in writing and in the form of a Notice of Conversion specifying (a) the
requested date of such Conversion, (b) the Type of Loan to be Converted,
(c) the portion of such Type of Loan to be Converted, (d) the Type of Loan
such Loan is to be Converted into and (e) if such Conversion is into a LIBOR
Loan, the requested duration of the Interest Period of such Loan.  Each
Notice of Conversion shall be irrevocable by and binding on the Borrower once
given.

Section 2.9.  Notes.

     (a)  Revolving Note.  The Revolving Loans made by each Lender shall, in
addition to this Agreement, also be evidenced by a promissory note of the
Borrower substantially in the form of Exhibit N (each a "Revolving Note"),
payable to the order of such Lender in a principal amount equal to the amount
of its Commitment as originally in effect and otherwise duly completed.

     (b)  Records; Endorsement on Transfer.  The date, amount of each
Revolving Loan made by each Lender to the Borrower, and each payment made
on account of the principal thereof, shall be recorded by such Lender on its
books and such entries shall be binding on the Borrower absent manifest
error.  Prior to the transfer of any Note, the Lender shall endorse such
items on such Note or any allonge thereof; provided that the failure of such
Lender to make any such recordation or endorsement shall not affect the
obligations of the Borrower to make a payment when due of any amount owing
hereunder or under such Note in respect of the Loans evidenced by such Note.

Section 2.10.  Reductions of the Commitments.

     (a)  Voluntary.  The Borrower shall have the right to terminate or
reduce the aggregate unused amount of the Commitments (for which purpose use
of the Commitments shall be deemed to include the aggregate amount of Letter
of Credit and the aggregate principal amount of all outstanding Swingline
Loans) at any time and from time to time without penalty or premium upon not
less than 5 Business Days prior written notice to the Agent of each such
termination or reduction, which notice shall specify the effective date
thereof and the amount of any such reduction and shall be irrevocable once
given and effective only upon receipt by the Agent.  The Agent will promptly
transmit such notice to each Lender.  The Commitments, once terminated or
reduced may not be increased or reinstated. Any reduction in the aggregate
amount of the Commitments shall result in a proportionate reduction (rounded
to the next lowest integral multiple of multiple of $100,000) in each of the
Swingline Commitment and the L/C Commitment Amount.

     (b)  Mandatory. To the extent Net Proceeds of the Seramed Disposition
are not within 540 days of receipt thereof either (i) used by the Borrower
to finance a Restricted Payment permitted under Section 9.6.(b)(ii) or
(ii) applied by the Loan Parties to finance Acquisitions or to acquire,
construct or improve properties or capital assets to be used by any of the
Loan Parties in the same or similar line(s) of business as those described
in Section 6.18., then the aggregate amount of the Commitments shall
automatically and permanently be reduced by an amount equal to such excess.

Section 2.11.  Expiration or Maturity Date of Letters of Credit Past
Termination Date.

     If on the date (the "Facility Termination Date") the Commitments are
terminated (whether voluntarily, by reason of the occurrence of an Event of
Default or otherwise), there are any Letters of Credit outstanding hereunder,
the Borrower shall, on the Facility Termination Date, pay to the Agent an
amount of money equal to the Stated Amount of such Letter(s) of Credit for
deposit into the Collateral Account.  If a drawing pursuant to any such
Letter of Credit occurs on or prior to the expiration date of such Letter of
Credit, the Borrower authorizes the Agent to use the monies deposited in the
Collateral Account to make payment to the beneficiary with respect to such
drawing or the payee with respect to such presentment.

Section 2.12.  Swingline Loans.

     (a)  Swingline Loans.  Subject to the terms and conditions hereof,
including without limitation, Section 2.13., the Swingline Lender agrees to
make Swingline Loans to the Borrower, during the period from the Closing
Date to but excluding the Termination Date, in an aggregate principal amount
at any one time outstanding up to, but not exceeding, the amount of the
Swingline Commitment.  If at any time the aggregate outstanding principal
amount of the Swingline Loans exceeds the Swingline Commitment in effect at
such time, the Borrower shall immediately pay to the Agent for the account
of the Swingline Lender the amount of such excess.  Subject to the terms and
conditions of this Agreement, the Borrower may borrow, repay and reborrow
Swingline Loans hereunder.  Except as otherwise provided in Section 2.10 ,
the borrowing of a Swingline Loan shall not constitute usage of any Lender's
Commitment for purposes of calculation of the fee payable under Section
3.6.(a) or otherwise.

     (b)  Procedure for Borrowing Swingline Loans.  With respect to any
Swingline Loan not being made to the Borrower as contemplated under
subsection (f) below, the Borrower shall give the Agent and Swingline Lender
notice pursuant to a Notice of Swingline Borrowing or otherwise given to the
Agent and Swingline Lender in such manner, and no later than such time, as
may be agreed to by the Borrower and the Swingline Lender in writing from
time to time. Not later than such time as may be agreed to by the Borrower
and the Swingline Lender from time to time and subject to satisfaction of
the applicable conditions set forth in Article V. for such borrowing, the
Swingline Lender will make the proceeds of such Swingline Loan available to
the Borrower in Dollars, in immediately available funds, at the account
specified by the Borrower in the Notice of Swingline Borrowing or as
otherwise directed by the Borrower in writing.

     (c)  Interest.  Swingline Loans shall bear interest (i) at a per annum
rate equal to the Base Rate (as in effect from time to time) per annum or
(ii) at such other rate or rates as the Borrower and Swingline Lender may
agree from time to time in writing.  Interest payable on Swingline Loans is
solely for the account of the Swingline Lender.  All accrued and unpaid
interest on Swingline Loans shall be payable on the dates and in the manner
provided in Section 2.3. with respect to interest on Base Rate Loans (except
as the Swingline Lender and the Borrower may otherwise agree in writing in
connection with any particular Swingline Loan).

     (d)  Swingline Note.  The Swingline Loans shall, in addition to this
Agreement, be evidenced by the Swingline Note.

     (e)  Repayment and Participations of Swingline Loans.  The Borrower
agrees to repay each Swingline Loan within one Business Day of demand
therefor by the Swingline Lender.  Notwithstanding the foregoing, the
Borrower shall repay the entire outstanding principal amount of, and all
accrued but unpaid interest on, the Swingline Loans on the Termination Date
(or such earlier date as the Swingline Lender and the Borrower may agree in
writing).  In lieu of demanding repayment of any outstanding Swingline Loan
from the Borrower, the Swingline Lender may at any time, on behalf of the
Borrower (which hereby irrevocably directs the Swingline Lender to act on
its behalf), request a borrowing of Base Rate Loans (which shall not be
subject to the amount limitations of Section 3.5.) from the Lenders in an
aggregate amount equal to the principal balance of such Swingline Loan.  The
Swingline Lender shall give notice to the Agent of any such borrowing of
 Base Rate Loans not later than 11:00 a.m. on the proposed date of such
borrowing.  Each Lender will make available to the Agent for the account
of the Swingline Lender, in immediately available funds, the proceeds of the
Loan to be made by such Lender.  The Agent shall pay the proceeds of such
Loans to the Swingline Lender, which shall apply such proceeds to repay such
Swingline Loan.  If Lenders are prohibited from making Loans required to be
made under this subsection for any reason whatsoever, including without
limitation, the occurrence of any of the Defaults or Events of Default
described in Sections 10.1.(e) or 10.1.(f), each Lender shall purchase from
the Swingline Lender, without recourse or warranty, an undivided interest
and participation to the extent of such Lender's Pro Rata Share of such
Swingline Loan, by directly purchasing a participation in such Swingline
Loan in such amount and paying the proceeds thereof to the Agent for the
account of the Swingline Lender in Dollars and in immediately available
funds.  A Lender's obligation to purchase such a participation in a Swingline
Loan shall be absolute and unconditional and shall not be affected by any
circumstance whatsoever, including without limitation, (i) any claim of
setoff, counterclaim, recoupment, defense or other right which such Lender
or any other Person may have or claim against the Agent, the Swingline Lender
or any other Person whatsoever, (ii) the occurrence or continuation of a
Default or Event of Default (including without limitation, any of the
Defaults or Events of Default described in Sections 10.1.(e) or (f)) or the
termination of any Lender's Commitment, (iii) the existence (or alleged
existence) of an event of condition which has had or could have a Material
Adverse Effect, (iv) any breach of any Credit Document by the Agent, any
Lender or the Borrower or (v) any other circumstance, happening or event
whatsoever, whether or not similar to any of the foregoing.  If such amount
is not in fact made available to the Swingline Lender by any Lender, the
Swingline Lender shall be entitled to recover such amount on demand from
such Lender, together with accrued interest thereon for each day from the
date of demand thereof, at the Federal Funds Rate.  If such Lender does not
pay such amount forthwith upon the Swingline Lender's demand therefor, and
until such time as such Lender makes the required payment, the Swingline
Lender shall be deemed to continue to have outstanding Swingline Loans in
the amount of such unpaid participation obligation for all purposes of the
Loan Documents (other than those provisions requiring the other Lenders to
purchase a participation therein).  Further, such Lender shall be deemed to
have assigned any and all payments made of principal and interest on its
Loans, and any other amounts due to it hereunder, to the Swingline Lender to
fund Swingline Loans in the amount of the participation in Swingline Loans
that such Lender failed to purchase pursuant to this Section until such
amount has been purchased (as a result of such assignment or otherwise).

     (f)  Auto Borrow/Auto Sweep Programs.  Until the occurrence of a Default
or Event of Default, at 5:00 p.m. on each Business Day the Borrower shall be
deemed to have requested that the Swingline Lender make to the Borrower a
Swingline Loan in an amount equal to the amount by which drafts against the
Operating Account exceed the available balance of funds then on deposit in
the Operating Account.  The Agent shall notify the Swingline Lender of the
amount of such excess.  The Swingline Lender shall make the proceeds of each
such Swingline Loan available to the Borrower by paying the same to the Agent
for deposit into the Operating Account.  At 5:00 p.m. on each Business Day,
the Borrower shall repay a principal amount of Swingline Loans by an amount
equal to the positive balance, if any, of available funds then on deposit in
the Operating Account as determined by the Agent at such time.  The Borrower
hereby authorizes the Agent to deduct such amount from the Operating Account
without notice to the Borrower, and to pay such amount to the Swingline
Lender in repayment of the then outstanding principal balance of Swingline
Loans.

Section 2.13.  Amount Limitations.

     Notwithstanding any other term of this Agreement or any other Credit
Document, at no time may the aggregate principal amount of all outstanding
Revolving Loans, together with the aggregate amount of all Letter of Credit
Liabilities and the aggregate principal amount of all outstanding Swingline
Loans, exceed the aggregate amount of the Commitments as in effect at that
time.

                      ARTICLE III. PAYMENTS, FEES AND OTHER GENERAL PROVISIONS

Section 3.1.  Payments.

     Except to the extent otherwise provided herein, all payments of
principal, interest and other amounts to be made by the Borrower under this
Agreement or any other Credit Document shall be made in Dollars, in
immediately available funds, without deduction, set-off or counterclaim,
to the Agent at its Principal Office, not later than 2:00 p.m. on the date
on which such payment shall become due (each such payment made after such
time on such due date to be deemed to have been made on the next succeeding
Business Day).  Subject to Sections 3.2. and 3.3., the Agent, or any Lender
for whose account any such payment is made, may (but shall not be obligated
to) debit the amount of any such payment which is not made by such time from
any special or general deposit account of the Borrower with the Agent or such
Lender, as the case may be (with notice to the Borrower, the other Lenders
and the Agent).  The Borrower shall, at the time of making each payment under
this Agreement or any Note, specify to the Agent the amounts payable by the
Borrower hereunder to which such payment is to be applied.  Each payment
received by the Agent for the account of a Lender under this Agreement or any
Note shall be paid to such Lender at the applicable Lending Office of such
Lender no later than 5:00 p.m. on the date of receipt.  Each payment received
by Agent for the account of Swingline Lender under this Agreement or the
Swingline Note shall be paid to Swingline Lender in accordance with the
payment instructions provided by Swingline Lender to the Agent from time to
time.  If the due date of any payment under this Agreement or any other
Credit Document would otherwise fall on a day which is not a Business Day
such date shall be extended to the next succeeding Business Day and interest
shall be payable for the period of such extension.

Section 3.2.  Pro Rata Treatment.

     Except to the extent otherwise provided herein: (a) each borrowing from
the Lenders under Section 2.1. (a) shall be made from the Lenders, each
payment of the Fees under Section 3.6.(a) and the first sentence of Section
3.6.(b) shall be made for the account of the Lenders, and each termination or
reduction of the amount of the Commitments under Section 2.10. or otherwise
shall be applied to the respective Commitments of the Lenders, pro rata
according to the amounts of their respective Commitments; (b) each payment
or prepayment of principal of Revolving Loans by the Borrower shall be made
for the account of the Lenders pro rata in accordance with the respective
unpaid principal amounts of the Revolving Loans held by them, provided that
if immediately prior to giving effect to any such payment in respect of any
Revolving Loans the outstanding principal amount of the Revolving Loans shall
not be held by the Lenders pro rata in accordance with their respective
Commitments in effect at the time such Loans were made, then such payment
shall be applied to the Revolving Loans in such manner as shall result, as
nearly as is practicable, in the outstanding principal amount of the
Revolving Loans being held by the Lenders pro rata in accordance with their
respective Commitments; (c) each payment of interest on Revolving Loans by
the Borrower shall be made for the account of the Lenders pro rata in
accordance with the amounts of interest on such Loans then due and payable
to the respective Lenders; (d) the making, Conversion and Continuation of
Revolving Loans of a particular Type (other than Conversions provided for by
Section 4.5.) shall be made pro rata among the Lenders according to the
amounts of their respective Commitments (in the case of making of Loans) or
their respective Loans (in the case of Conversions and Continuations of
Loans) and the then current Interest Period for each Lender's portion of each
Loan of such Type shall be coterminous; and (e) the Lenders' participation
in, and payment obligations in respect of, Letters of Credit under Section
2.2. and Swingline Loans under Section 2.12., shall be pro rata in accordance
with their respective Commitments.

Section 3.3.  Sharing of Payments, Etc.

     If a Lender shall obtain payment of any principal of, or interest on,
any Loan made by it to the Borrower under this Agreement, or shall obtain
payment on any other Obligation owing by the Borrower or a Loan Party through
the exercise of any right of set-off, banker's lien or counterclaim or
similar right or otherwise or through voluntary prepayments directly to a
Lender or other payments made by the Borrower to a Lender not in accordance
with the terms of this Agreement and such payment should be distributed to
the Lenders pro rata in accordance with Section 3.2. or Section 10.4., as
applicable, such Lender shall promptly pay such amounts to the other Lenders
and make such other adjustments from time to time as shall be equitable, to
the end that all the Lenders shall share the benefit of such payment (net of
any reasonable expenses which may be incurred by such Lender in obtaining or
preserving such benefit) pro rata in accordance with Section 3.2. or Section
10.4.  To such end, all the Lenders shall make appropriate adjustments among
themselves (by the resale of participations sold or otherwise) if such
payment is rescinded or must otherwise be restored.  The Borrower agrees that
any Lender so purchasing a participation (or direct interest) in the Loans or
other Obligations owed to such other Lenders may exercise all rights of
set-off, banker's lien, counterclaim or similar rights with respect to such
participation as fully as if such Lender were a direct holder of Loans in the
amount of such participation.  Nothing contained herein shall require any
Lender to exercise any such right or shall affect the right of any Lender to
exercise, and retain the benefits of exercising, any such right with respect
to any other indebtedness or obligation of the Borrower. All payments of
principal, interest, fees and other amounts in respect of the Swingline Loans
shall be for the account of Swingline Lender only (except to the extent any
Lender shall have acquired a participating interest in any such Swingline
Loan pursuant to Section 2.12.(e)).

Section 3.4.  Several Obligations.

     No Lender shall be responsible for the failure of any other Lender to
make a Loan or to perform any other obligation to be made or performed by
such other Lender hereunder, and the failure of any Lender to make a Loan or
to perform any other obligation to be made or performed by it hereunder shall
not relieve the obligation of any other Lender to make any Loan or to perform
any other obligation to be made or performed by such other Lender.

Section 3.5.  Minimum Amounts.

     (a)  Borrowings.  Each borrowing of Base Rate Loans shall be in an
aggregate minimum amount of $1,000,000 and integral multiples of $100,000 in
excess thereof.  Each borrowing of LIBOR Loans shall be in an aggregate
minimum amount of $1,000,000 and integral multiples of $100,000 in excess of
that amount.

     (b)  Prepayments.  Each voluntary prepayment of Revolving Loans shall be
in an aggregate minimum amount of $1,000,000 and integral multiples of
$100,000 in excess thereof (or such lesser amount as may be the outstanding
principal amount of such Revolving Loans).

     (c)  Reductions of Commitments.  Each reduction of the Commitments under
Section 2.10. shall be in an aggregate minimum amount of $500,000 and
integral multiples of $100,000 in excess thereof (or such lesser amount as
may be the remaining aggregate amount of the Commitments).

     (d)  Conversions.  Each Conversion of a Loan from a Base Rate Loan to
a LIBOR Loan shall be in an aggregate minimum amount for the Loans of all
Lenders of $1,000,000 or integral multiples of $100,000 in excess thereof.

     (e)  Letters of Credit.  The initial Stated Amount of each Letter of
Credit shall be at least $50,000.

Section 3.6.  Fees.

     (a)  Commitment Fee.  The Borrower agrees to pay to the Agent for the
account of the Lenders a commitment fee on the average daily amount by which
the Commitments (as the amount of the Commitments may be reduced from time to
time pursuant to Section 2.10. or otherwise) exceed the aggregate principal
balance of all outstanding Revolving Loans, together with the aggregate
amount of all Letter of Credit Liabilities, at a rate per annum equal to the
Applicable Commitment Fee for the period from and including the Agreement
Date to but excluding earlier of the date the Commitments are terminated or
reduced to zero or the Termination Date.  As provided in the last sentence of
Section 2.12. (a), the borrowing of a Swingline Loan shall not constitute
usage of any Lender's Commitment for purposes of calculating such commitment
fee.  Such commitment fee shall be payable in arrears on (i) the last
Business Day of March, June, September and December in each year commencing
with September 30, 1999, (ii) on the Termination Date, and (iii) on the date
the Commitments are otherwise terminated or reduced to zero.

     (b)  Letter of Credit Fees.  The Borrower agrees to pay to the Agent for
the account of each Lender a letter of credit fee at a rate per annum equal
to the Applicable Margin for LIBOR Loans of the daily average Stated Amount
of each Letter of Credit for the period from and including the date of
issuance of such Letter of Credit to and including the date such Letter of
Credit is drawn in full, expires or is terminated. The fees provided for in
the immediately preceding sentence shall be nonrefundable and paid in arrears
(i) the last Business Day of March, June, September and December in each year
commencing with September 30, 1999, (ii) on the Termination Date, (iii) on
the date the Commitments are terminated or reduced to zero and
(iv) thereafter from time to time on demand of the Agent.  The Borrower shall
pay directly to the Agent from time to time on demand all commissions,
charges, costs and expenses in the amounts customarily charged by the Agent
from time to time in like circumstances with respect to the issuance of each
Letter of Credit, drawings, amendments and other transactions relating
thereto.

     (c)  Administrative and Other Fees.  The Borrower agrees to pay the
administrative and other fees of the Agent and BAS, and any other Fees of the
Lenders, as may be agreed to in writing from time to time.

Section 3.7.  Computations.

     Unless otherwise expressly set forth herein, any accrued interest on any
Loan and any other Obligations due hereunder, and any Fees due hereunder,
shall be computed on the basis of a year of 360 days and the actual number of
days elapsed; provided, however, accrued interest on any Base Rate Loan shall
be computed on the basis of a year of 365 or 366 days, as applicable, and the
actual number of days elapsed.

Section 3.8.  Usury.

     In no event shall the amount of interest due or payable on the Loans or
other Obligations exceed the maximum rate of interest allowed by Applicable
Law and, if any such payment is paid by the Borrower or received by any
Lender, then such excess sum shall be credited as a payment of principal,
unless the Borrower shall notify the respective Lender in writing that the
Borrower elects to have such excess sum returned to it forthwith.  It is
the express intent of the parties hereto that the Borrower not pay and the
Lenders not receive, directly or indirectly, in any manner whatsoever,
interest in excess of that which may be lawfully paid by the Borrower under
Applicable Law.

Section 3.9.  Agreement Regarding Interest and Charges.

     The parties hereto hereby agree and stipulate that the only charge
imposed upon the Borrower for the use of money in connection with this
Agreement is and shall be the interest specifically described in Section
2.3.(a) and, with respect to Swingline Loans, in Section 2.12.(c).
Notwithstanding the foregoing, the parties hereto further agree and stipulate
that all agency fees, syndication fees, commitment fees, letter of credit
fees, underwriting fees, default charges, late charges, funding or "breakage"
charges, increased cost charges, attorneys' fees and reimbursement for costs
and expenses paid by the Agent or any Lender to third parties or for damages
incurred by the Agent or any Lender, are charges made to compensate the Agent
or any such Lender for underwriting or administrative services and costs or
losses performed or incurred, and to be performed or incurred, by the Agent
and the Lenders in connection with this Agreement and shall under no
circumstances be deemed to be charges for the use of money pursuant to
Official Code of Georgia Annotated Sections 7-4-2 and 7-4-18.  All charges
other than charges for the use of money shall be fully earned and
nonrefundable when due.

Section 3.10.  Statements of Account.

     The Agent will account to the Borrower with a statement of Loans,
Letters of Credit, accrued interest and Fees, charges and payments made
pursuant to this Agreement and the other Credit Documents, and such statement
rendered by the Agent shall be deemed conclusive upon Borrower absent
manifest error.  The failure of the Agent to deliver such a statement shall
not relieve or discharge the Borrower from any of its obligations hereunder.

Section 3.11.  Defaulting Lenders.

     (a)  Generally.  If for any reason any Lender (a "Defaulting Lender")
shall fail or refuse to perform any of its obligations under this Agreement
or any other Credit Document to which it is a party within the time period
specified for performance of such obligation or, if no time period is
specified, if such failure or refusal continues for a period of two Business
Days after notice from the Agent, then, in addition to the rights and
remedies that may be available to the Agent or the Borrower under this
Agreement or Applicable Law, such Defaulting Lender's right to participate
in the administration of the Loans, this Agreement and the other Credit
Documents, including without limitation, any right to vote in respect of,
to consent to or to direct any action or inaction of the Agent or to be taken
into account in the calculation of the Requisite Lenders, shall be suspended
during the pendency of such failure or refusal.  If a Lender is a Defaulting
Lender because it has failed to make timely payment to the Agent of any
amount required to be paid to the Agent hereunder (without giving effect to
any notice or cure periods), in addition to other rights and remedies which
the Agent or the Borrower may have under the immediately preceding provisions
or otherwise, the Agent shall be entitled (i) to collect interest from such
Defaulting Lender on such delinquent payment for the period from the date on
which the payment was due until the date on which the payment is made at the
Federal Funds Rate, (ii) to withhold or setoff and to apply in satisfaction
of the defaulted payment and any related interest, any amounts otherwise
payable to such Defaulting Lender under this Agreement or any other Credit
Document and (iii) to bring an action or suit against such Defaulting Lender
in a court of competent jurisdiction to recover the defaulted amount and any
related interest.  Any amounts received by the Agent in respect of a
Defaulting Lender's Loans shall not be paid to such Defaulting Lender and
shall be held uninvested by the Agent and either applied against the purchase
price of such Loans under the following subsection (b) or paid to such
Defaulting Lender upon the Defaulting Lender's curing of its default.

     (b)  Purchase of Defaulting Lender's Commitment.  Any Lender who is not
a Defaulting Lender shall have the right, but not the obligation, in its sole
discretion, to acquire all of a Defaulting Lender's Commitment.  Any Lender
desiring to exercise such right shall give written notice thereof to the
Agent no sooner than 2 Business Days and not later than 10 Business Days
after such Defaulting Lender became a Defaulting Lender.  If more than one
Lender exercises such right, each such Lender shall have the right to acquire
an amount of such Defaulting Lender's Commitment in proportion to the
Commitments of the other Lenders exercising such right.  If after such 10th
Business Day, the Lenders have not elected to purchase all of the Commitment
of such Defaulting Lender, then any Eligible Assignee may purchase such
Commitment.  Neither the Agent nor any of the Lenders shall have any
obligation whatsoever to initiate any such replacement or to assist in
finding an Eligible Assignee.  Upon any such purchase, the Defaulting
Lender's interest in the Loans and its rights hereunder (but not its
liability in respect thereof or under the Credit Documents or this Agreement
to the extent the same relate to the period prior to the effective date of
the purchase) shall terminate on the date of purchase, and the Defaulting
Lender shall promptly execute all documents reasonably requested to surrender
and transfer such interest to the purchaser thereof, including an appropriate
Assignment and Acceptance Agreement and, notwithstanding Section 12.5(d),
shall pay to the Agent an assignment fee in the amount of $7,000.  The
purchase price for the Commitment of a Defaulting Lender shall be equal to
the amount of the principal balance of the Loans outstanding and owed by the
Borrower to the Defaulting Lender.  Prior to payment of such purchase price
to a Defaulting Lender, the Agent shall apply against such purchase price any
amounts retained by the Agent pursuant to the last sentence of the
immediately preceding subsection (a).  The Defaulting Lender shall be
entitled to receive amounts owed to it by the Borrower under the Credit
Documents which accrued prior to the date of the default by the Defaulting
Lender, to the extent the same are received by the Agent from or on behalf of
the Borrower.  There shall be no recourse against any Lender or the Agent for
the payment of such sums except to the extent of the receipt of payments from
any other party or in respect of the Loans.  If, prior to a Lender's
acquisition of a Defaulting Lender's Commitment pursuant to this subsection,
such Defaulting Lender shall cure the event or condition which caused it to
become a Defaulting Lender to the satisfaction of the Agent and shall have
paid all amounts owing by it hereunder as a result thereof, then such Lender
shall no longer have the right to acquire such Defaulting Lender's
Commitment.

Section 3.12.  Taxes.

     (a)  Taxes Generally.  All payments by the Borrower of principal of, and
interest on, the Loans and all other Obligations shall be made free and clear
of and without deduction for any present or future excise, stamp or other
taxes, fees, duties, levies, imposts, charges, deductions, withholdings or
other charges of any nature whatsoever imposed by any taxing authority, but
excluding the following (collectively, "Excluded Taxes"): (i) franchise
taxes, (ii) any taxes (other than withholding taxes) that would not be
imposed but for a connection between the Agent or a Lender and the
jurisdiction imposing such taxes (other than a connection arising solely by
virtue of the activities of the Agent or such Lender pursuant to or in
respect of this Agreement or any other Credit Document), (iii) any taxes
imposed on or measured by any Lender's assets, net income, receipts or branch
profits and (iv) any taxes arising after the Agreement Date solely as a
result of or attributable to a Lender changing its designated Lending Office
after the date such Lender becomes a party hereto (such items other than
Excluded Taxes being collectively called "Taxes").  If any withholding or
deduction from any payment to be made by the Borrower hereunder is required
in respect of any Taxes pursuant to any Applicable Law, then the Borrower
will:

             (i)  pay directly to the relevant Governmental Authority the
      full amount required to be so withheld or deducted;

            (ii)  promptly forward to the Agent an official receipt or other
      documentation reasonably satisfactory to the Agent evidencing such
      payment to such Governmental Authority; and

           (iii)  pay to the Agent for its account or the account of the
      applicable Lender, as the case may be, such additional amount or
      amounts as is necessary to ensure that the net amount actually received
      by the Agent or such Lender will equal the full amount that the Agent
      or such Lender would have received had no such withholding or deduction
      been required.

     (b)  Tax Indemnification.  If the Borrower fails to pay any Taxes when
due to the appropriate Governmental Authority or fails to remit to the Agent,
for its account or the account of the respective Lender, as the case may be,
the required receipts or other required documentary evidence, the Borrower
shall indemnify the Agent and the Lenders for any incremental Taxes, interest
or penalties that may become payable by the Agent or any Lender as a result
of any such failure.  For purposes of this Section, a distribution hereunder
by the Agent or any Lender to or for the account of any Lender shall be
deemed a payment by the Borrower.

     (c)  Tax Forms.  Prior to the date that any Lender or participant
organized under the laws of a jurisdiction outside the United States of
America becomes a party hereto, such Person shall deliver to the Borrower and
the Agent such certificates, documents or other evidence, as required by the
Code or Treasury Regulations issued pursuant thereto (including Internal
Revenue Service Forms 4224 or 1001, as applicable, or appropriate successor
forms), properly completed, currently effective and duly executed by such
Lender or participant establishing that payments to it hereunder and under
the Notes are (i) not subject to United States Federal backup withholding tax
or (ii) not subject to United States Federal withholding tax under the Code
because such payment is either effectively connected with the conduct by such
Lender or participant of a trade or business in the United States or totally
exempt from United States Federal withholding tax by reason of the
application of the provisions of a treaty to which the United States is a
party or such Lender is otherwise exempt.  Any Lender who fails to remit to
the Borrower or the Agent any such required certificates, documents, evidence
or necessary forms shall reimburse the Borrower and the Agent for any
penalties paid by the Borrower or the Agent, as applicable, to the extent
resulting of the failure of the Borrower or the Agent, as applicable, to
withhold the required amounts that are caused by such Lender's failure to
provide such items when due.

     (d)  Refunds and Credits.  If the Agent or any Lender shall become aware
that it is entitled to a refund or credit in respect of Taxes for which it
has been indemnified by the Borrower pursuant to this Section, the Agent or
such Lender shall promptly notify the Borrower of the availability of such
refund or credit and shall, within 30 days after receipt of a written request
by the Borrower, apply for such refund or credit at the Borrower's sole cost
and expense.  So long as no Default or Event of Default shall have occurred
and be continuing, if the Agent or any Lender shall receive a refund or
credit in respect of any such Taxes as to which it has been indemnified by
the Borrower pursuant to this Section, the Agent or such Lender shall
promptly notify the Borrower of such refund or credit and shall, within
10 days of receipt or any refund or the effective date of any credit, pay
such refund or an amount equal to the amount of such credit, as the case may
be, but only to the extent of amounts that have been paid by the Borrower
under this Section with respect to such refund and not previously reimbursed,
to the Borrower, net of all reasonable out-of-pocket expenses of such Lender
or the Agent and without interest (other than the interest, if any, included
in such refund or in respect of such credit).

                              ARTICLE IV. YIELD PROTECTION, ETC.

Section 4.1.  Additional Costs; Capital Adequacy.

     (a)  Additional Costs.  The Borrower shall promptly pay to the Agent for
the account of a Lender from time to time such amounts as such Lender may
determine in good faith to be necessary to compensate such Lender for any
costs incurred by such Lender that it reasonably determines are attributable
to its making or maintaining of any Loans or its obligation to make any Loans
hereunder, any reduction in any amount receivable by such Lender under this
Agreement or any of the other Credit Documents in respect of any of such
Loans or such obligation or the maintenance by such Lender of capital in
respect of its Loans or its Commitments (such increases in costs and
reductions in amounts receivable being herein called "Additional Costs"),
resulting from any Regulatory Change that: (i) changes the basis of taxation
of any amounts payable to such Lender under this Agreement or any of the
other Credit Documents in respect of any of such Loans or its Commitments
(other than with respect to Excluded Taxes); or (ii) imposes or modifies any
reserve, special deposit or similar requirements (including, without
limitation, any reserves required to be maintained against (1)  "Eurocurrency
liabilities" as specified in Regulation D of the Board of Governors of the
Federal Reserve System or (2) any other category of liabilities which
includes deposits by reference to which the interest rate on LIBOR Loans is
determined or (3) any category of extensions of credit or other assets which
includes loans by an office of any Lender outside of the United States of
America to residents of the United States of America))  relating to any
extensions of credit or other assets of, or any deposits with or other
liabilities of, such Lender, or any commitment of such Lender (including,
without limitation, the Commitments of such Lender hereunder); or (iii) has
or would have the effect of reducing the rate of return on capital of such
Lender to a level below that which such Lender could have achieved but for
such Regulatory Change (taking into consideration such Lender's policies with
respect to capital adequacy).

     (b)  Lender's Suspension of LIBOR Loans.  Without limiting the effect of
the provisions of the immediately preceding subsection (a), if by reason of
any Regulatory Change, any Lender either (i) incurs Additional Costs based on
or measured by the excess above a specified level of the amount of a category
of deposits or other liabilities of such Lender that includes deposits by
reference to which the interest rate on LIBOR Loans is determined as provided
in this Agreement or a category of extensions of credit or other assets of
such Lender that includes LIBOR Loans or (ii) becomes subject to restrictions
on the amount of such a category of liabilities or assets that it may hold,
then, if such Lender so elects by notice to the Borrower (with a copy to the
Agent), the obligation of such Lender to make or Continue, or to Convert any
other Type of Loans into, LIBOR Loans hereunder shall be suspended until such
Regulatory Change ceases to be in effect (in which case the provisions of
Section 4.5. shall apply).

     (c)  Additional Costs in Respect of Letters of Credit.  Without limiting
the obligations of the Borrower under the preceding subsections of this
Section (but without duplication), if as a result of any Regulatory Change or
any risk-based capital guideline or other requirement heretofore or hereafter
issued by any Governmental Authority there shall be imposed, modified or
deemed applicable any tax, reserve, special deposit, capital adequacy or
similar requirement against or with respect to or measured by reference to
Letters of Credit and the result shall be to increase the cost to the Agent
of issuing (or any Lender purchasing participations in) or maintaining its
obligation hereunder to issue (or purchase participations in) any Letter of
Credit or reduce any amount receivable by the Agent or any Lender hereunder
in respect of any Letter of Credit, then, upon demand by the Agent or such
Lender, the Borrower shall pay immediately to the Agent for its account or
the account of such Lender, as applicable, from time to time as specified by
the Agent or a Lender, such additional amounts as the Agent or such Lender,
as the case may be, shall have determined in good faith to be sufficient to
compensate the Agent or such Lender for such increased costs or reductions in
amount.

     (d)  Notification and Determination of Additional Costs.  Each of the
Agent and each Lender agrees to notify the Borrower of any event occurring
after the Agreement Date entitling the Agent or such Lender to compensation
under any of the preceding subsections of this Section as promptly as
practicable; provided, however, the failure of the Agent or any Lender to
give such notice shall not release the Borrower from any of its obligations
hereunder.  The Agent and or such Lender agrees to furnish to the Borrower a
certificate setting forth the basis and amount of each request by the Agent
or such Lender for compensation under this Section.  Determinations by the
Agent or any Lender of the effect of any Regulatory Change shall be
conclusive, absent manifest error and provided that such determinations are
made reasonably and in good faith.

Section 4.2.  Suspension of LIBOR Loans.

     Anything herein to the contrary notwithstanding, if, on or prior to the
determination of any Adjusted Eurodollar Rate for any Interest Period:

            (a)  the Agent determines reasonably and in good faith (which
     determination shall be conclusive) that by reason of circumstances
     affecting the relevant market, adequate and reasonable means do not
     exist for ascertaining the Adjusted Eurodollar Rate for such Interest
     Period, or

            (b)  the Agent reasonably determines (which determination shall
     be conclusive) that the Adjusted Eurodollar Rate will not adequately and
     fairly reflect the cost to the Lenders of making or maintaining LIBOR
     Loans for such Interest Period;

then the Agent shall give the Borrower and each Lender prompt notice thereof
and, so long as such condition remains in effect, the Lenders shall be under
no obligation to, and shall not, make additional LIBOR Loans, Continue LIBOR
Loans or Convert Loans into LIBOR Loans and the Borrower shall, on the last
day of each current Interest Period for each outstanding LIBOR Loan, either
repay such Loan or Convert such Loan into a Base Rate Loan.

Section 4.3.  Illegality.

     Notwithstanding any other provision of this Agreement, if it becomes
unlawful for any Lender  to honor its obligation to make or maintain LIBOR
Loans hereunder, then such Lender shall promptly notify the Borrower thereof
(with a copy to the Agent) and such Lender's obligation to make or Continue,
or to Convert Loans of any other Type into, LIBOR Loans shall be suspended
until such time as such Lender may again make and maintain LIBOR Loans (in
which case the provisions of Section 4.5. shall be applicable).

Section 4.4.  Compensation.

     The Borrower shall pay to the Agent for the account of each Lender, upon
the request of such Lender through the Agent, such amount or amounts as shall
be sufficient to compensate such Lender for any loss, cost or expense that
such Lender determines in good faith is attributable to:

            (a)  any payment or prepayment (whether mandatory or optional) of
     a LIBOR Loan, or Conversion of a LIBOR Loan, made by such Lender for any
     reason (including, without limitation, acceleration) on a date other
     than the last day of the Interest Period for such Loan; or

            (b)  any failure by the Borrower for any reason (including,
     without limitation, the failure of any of the applicable conditions
     precedent specified in Article V. to be satisfied) to borrow a LIBOR
     Loan from such Lender on the requested date for such borrowing, or to
     Convert a Base Rate Loan into a LIBOR Loan or Continue a LIBOR Loan on
     the requested date of such Conversion or Continuation,

such compensation to include, without limitation, an amount equal to the
excess, if any, of (i) the amount of interest that otherwise would have
accrued on the principal amount so paid, prepaid or Converted or not borrowed
for the period from the date of such payment, prepayment, Conversion or
failure to borrow or Convert to the last day of the then current Interest
Period for such Loan (or, in the case of a failure to borrow or Convert, the
Interest Period for such Loan that would have commenced on the date specified
for such borrowing or Conversion) at the applicable rate of interest for such
Loan provided for herein plus such Lender's normal administrative charges, if
any, associated with such payment, prepayment, Conversion or failure to
borrow over (ii) the amount of interest that otherwise would have accrued on
such principal amount at a rate per annum equal to LIBOR at such time for an
amount comparable to such principal amount and for a maturity comparable to
such period (as reasonably determined by such Lender).  Upon the Borrower's
request, any Lender requesting compensation under this Section shall provide
the Borrower with a statement setting forth the basis for requesting such
compensation and the method for determining the amount thereof.  Any such
statement shall be conclusive absent manifest error.

Section 4.5.  Treatment of Affected Loans.

     If the obligation of any Lender to make LIBOR Loans or to Continue, or
to Convert Base Rate Loans into, LIBOR Loans shall be suspended pursuant to
Section 4.1.(b), 4.2. or 4.3., then such Lender's LIBOR Loans shall be
automatically Converted into Base Rate Loans on the last day(s) of the then
current Interest Period(s) for LIBOR Loans (or, in the case of a Conversion
required by Section 4.1.(b) or 4.3., on such earlier date as such Lender may
specify to the Borrower with a copy to the Agent) and, unless and until such
Lender gives notice as provided below that the circumstances specified in
Section 4.1., 4.2. or 4.3. that gave rise to such Conversion no longer exist:

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

           (b)  all Loans that would otherwise be made or Continued by such
     Lender as LIBOR Loans shall be made or Continued instead as Base Rate
     Loans, and all Base Rate Loans of such Lender that would otherwise be
     Converted into LIBOR Loans shall remain as Base Rate Loans.

If such Lender gives notice to the Borrower (with a copy to the Agent) that
the circumstances specified in Section 4.1. or 4.3. that gave rise to the
Conversion of such Lender's LIBOR Loans pursuant to this Section no longer
exist (which such Lender agrees to do promptly upon such circumstances
ceasing to exist) at a time when LIBOR Loans made by other Lenders are
outstanding, then such Lender's Base Rate Loans shall be automatically
Converted, on the first day(s) of the next succeeding Interest Period(s)
for such outstanding LIBOR Loans, to the extent necessary so that, after
giving effect thereto, all Loans held by the Lenders holding LIBOR Loans
and by such Lender are held pro rata (as to principal amounts, Types and
Interest Periods) in accordance with their respective Commitments.

Section 4.6.  Change of Lending Office.

     Each Lender agrees that it will use reasonable efforts to designate an
alternate Lending Office with respect to any of its Loans affected by the
matters or circumstances described in Sections 3.12., 4.1. or 4.3. to reduce
the liability of the Borrower or avoid the results provided thereunder, so
long as such designation is not disadvantageous to such Lender as determined
by such Lender in its sole discretion, except that such Lender shall have no
obligation to designate a Lending Office located in the United States of
America.

Section 4.7.  Assumptions Concerning Funding of LIBOR Loans.

     Calculation of all amounts payable to a Lender under this Article IV.
shall be made as though such Lender had actually funded  LIBOR Loans through
the purchase of deposits in the relevant market bearing interest at the rate
applicable to such LIBOR Loans in an amount equal to the amount of the LIBOR
Loans and having a maturity comparable to the relevant Interest Period;
provided, however, that each Lender may fund each of its LIBOR Loans in any
manner it sees fit and the foregoing assumption shall be used only for
calculation of amounts payable under this Article IV.

Section 5.2.  Conditions Precedent to All Loans and Letters of Credit.

     The obligation of the Lenders to make any Loans, of the Swingline Lender
to make any Swingline Loan and of the Agent to issue Letters of Credit, in
each case, is subject to the further condition precedent that: (a) no Default
or Event of Default shall have occurred and be continuing as of the date of
the making of such Loan or date of issuance of such Letter of Credit or would
exist immediately after giving effect thereto; (b) the representations and
warranties made or deemed made by the Borrower and each other Loan Party in
the Credit Documents to which any of them is a party, shall be true and

effect as if made on and as of such date except to the extent that such
representations and warranties expressly relate solely to an earlier date (in
which case such representations and warranties shall have been true and
accurate on and as of such earlier date) and (c) in the case of the borrowing
of Revolving Loans, the Agent shall have received a timely Notice of
Borrowing, or in the case of a Swingline Loan, timely receipt by Swingline
Lender of a Notice of Swingline Borrowing.  Each Credit Event (including

forth in the preceding sentence (both as of the date of the giving of notice
relating to such Credit Event and, unless the Borrower otherwise notifies the

occurrence of such Credit Event).  The making of any Loans by the Lenders or
the Swingline Lender, or issuance of a Letter of Credit by the Agent, prior
to the satisfaction of all applicable conditions contained in Article V.,
shall not constitute nor be construed to be a waiver by the Lenders, the
Swingline Lender or the Agent, of the requirement that such conditions be
satisfied.

     In order to induce the Agent, each Lender and the Swingline Lender to
enter into this Agreement and to make Loans, issue Letters of Credit and make
Swingline Loans, as applicable, the Borrower represents and warrants to the
Agent, the Lenders and the Swingline Lender as follows:

Section 6.1.  Corporate Existence

     Each of the Borrower and the other Loan Parties (a) is a corporation,
partnership or other legal entity, duly organized or formed and validly
existing; (b) has all requisite power, and has all governmental licenses,
authorizations, consents and approvals, necessary to own its assets and carry
on its business as now being or as proposed to be conducted and to consummate
the Transactions, except where the failure to have such requisite power, or
have such governmental licenses, authorizations, consents or approvals could
not reasonably be expected to have a Material Adverse Effect; and (c) is in
good standing under the laws of the jurisdiction of its organization or
formation and is qualified to do business in all jurisdictions in which the
nature of the business conducted by it makes such qualification necessary,
except where failure to be in good standing or so to qualify could not
reasonably be expected to have a Material Adverse Effect, all of which such
jurisdictions are set forth on Schedule 6.1.

Section 6.2.  Authorization; No Conflict

     The execution, delivery and performance by the Borrower and the other
Loan Parties of each of the Credit Documents and the Acquisition Documents to
which any is a party and the consummation of the Transactions (a) have been
duly authorized by all requisite corporate and, if required, stockholder
action on the part of the Borrower and each such Loan Party and (b) will not
(i) to the  actual knowledge of a Responsible Officer of the Borrower,
violate any provision of Applicable Law, or any order of any Governmental
Authority, (ii) violate any provision of the organizational documents of the
Borrower or any other Loan Party, (iii) violate, conflict with, result in a
breach of, or constitute (alone or with notice or lapse of time or both) a
default or an event of default under, any Material Contract to which the
Borrower or any other Loan Party is a party or by which the Borrower or any
other Loan Party or any of its property is or may be bound, or (iv) result in
the creation or imposition of any Lien upon any property or assets of the
Borrower or any other Loan Party (except pursuant to the Security Documents).

Section 6.3.  Enforceability

     This Agreement, each other Credit Document, and each Acquisition
Document have been duly executed and delivered by the Borrower and each of
the other Loan Parties (to the extent it is a party thereto) and constitute
the legal, valid and binding obligations of the Borrower and the other Loan
Parties enforceable against the Borrower and the other Loan Parties in
accordance with their respective terms, except (a) as the same may be limited
by bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance
or other laws affecting generally the enforcement of creditors' rights and by
general principles of equity (regardless of whether considered in a
proceeding in equity or at law) and (b) that obligations of a Loan Party
resulting solely from being jointly and severally liable under a Credit
Document for the obligations (the "Primary Obligations") of another Loan
Party primarily responsible for the performance of such Primary Obligations
may not be enforceable; provided, however, the lack of such enforceability
does not (i) limit in any way the enforceability of any of the Primary
Obligations and (ii) does not make the principal remedies afforded by such
Credit Document inadequate for the practical realization of the principal
rights, benefits or security provided thereby.

Section 6.4.  Approvals

     To the actual knowledge of any Responsible Officer of the Borrower, no
authorizations, approvals or consents of, no filings or registrations with,
and notices to any Governmental Authority are necessary for the execution,
delivery or performance by the Borrower and the other Loan Parties of the
Credit Documents, and the Acquisition Documents to which any of them is a
party or for the validity or enforceability thereof, except for (a) filings
and recordings in respect of the Liens created pursuant to the Security
Documents, (b) such authorizations, approvals, consents, filings,
registrations or notices as shall have been previously obtained and which
remain in effect.

Section 6.5.  Financial Condition

     (a)  The Historical Financial Statements are materially complete and
correct and fairly present the financial condition and results of operations
of the Borrower and its Consolidated Subsidiaries as of and for the periods
covered thereby.  There has been no material adverse change in the business,
property, assets, liabilities, condition (financial or otherwise),
operations, results of operations or prospects of the Borrower and its
Subsidiaries taken as a whole since the date of the audited financial
statements of the Borrower most recently delivered to the Agent under Section
5.1. or 8.2., as applicable.

     (b)  Except as set forth on Schedule 6.6. or in the financial statements
or notes thereto most recently delivered to the Agent under Section 8.1. or
8.2., to the  actual knowledge of any Responsible Officer of the Borrower,
the Borrower and its Subsidiaries have no liabilities, contingent or
otherwise, which could reasonably be expected to have a Material Adverse
Effect.

     (c)  Except as otherwise disclosed in writing to the Agent and the
Lenders, to the actual knowledge of any Responsible Officer of the Borrower,
(i) the Acquisition Historical Financial Statements of the Seller fairly
present the financial condition and results of operations of the Seller as of
and for the periods covered thereby; (ii) the Acquisition Pro Forma Financial
Statements of the Seller, the Borrower and its Consolidated Subsidiaries
fairly present the combined financial condition and results of operations of
the Seller, the Borrower and its Consolidated Subsidiaries as of and for the
periods covered thereby and (iii) there has been no material adverse change
in the business, property, assets, liabilities, condition (financial or
otherwise), operations, results of operations or prospects of the Seller
since the end of such Seller's immediately preceding fiscal year.

Section 6.6.  Litigation

     Except as set forth on Schedule 6.6. or in any written notice delivered
by the Borrower pursuant to Section 8.4.(c)(D) or Section 8.5., there are no
actions, suits or proceedings at law or in equity by or before any
Governmental Authority now pending or, to the  actual knowledge of any
Responsible Officer of the Borrower, threatened against the Borrower or any
other Loan Party or their respective business, property or rights (i) which
involve any Credit Document, any Acquisition Document or any Transaction or
(ii) which, if adversely determined could reasonably be expected to,
individually or in the aggregate, have a Material Adverse Effect.  There
exists no judgment, order, injunction or other restraint issued or filed
which is material to the Borrower or any other Loan Party, or any of their
respective businesses, properties or rights, or which prohibits or adversely
affects any of the Transactions.

Section 6.7.  Federal Reserve Regulations

     Neither the Borrower nor any of the other Loan Parties is engaged in the
business of extending credit for the purpose, whether immediate, incidental
or ultimate, of buying or carrying Margin Stock.  No part of the proceeds of
any extension of credit hereunder, whether directly or indirectly, and
whether immediately, incidentally or ultimately, will be used (i) to purchase
or carry Margin Stock or to extend credit to others for the purpose of
purchasing or carrying Margin Stock or to refund indebtedness originally
incurred for such purpose, or (ii) for any purpose which entails a violation
of, or which is inconsistent with, the provisions of the Regulations of the
Board of Governors of the Federal Reserve System, including Regulations T, U
or X.  As used herein, the term "Margin Stock" shall mean margin stock within
the meaning of Regulations T, U and X.

Section 6.8.  ERISA

     (a)  Neither the Borrower nor any other Loan Party maintains or
contributes to any Employee Benefit Plan or Multiemployer Plan other than
those identified on Schedule 6.8. and those of which the Borrower has given
written notice to the Agent and the Lenders after the date of this Agreement.

     (b)  The Borrower and each other Loan Party are in compliance in all
material respects with all applicable provisions of ERISA and the Code with
respect to all Employee Benefit Plans.  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 from federal income tax under
Section 501(a) of the Code.  The actuarial present value of all accumulated
benefit obligations under each Plan, as disclosed in the most recent
actuarial report with respect to such Plan, does not exceed the fair market
value of the assets of such Plan.  No material liability has been incurred by
the Borrower or any other Loan Party or any of their ERISA Affiliates which

circumstances in which the same were made.  All financial projections
concerning the Borrower and its Subsidiaries that have been or are hereafter
made available to the Agent, any Lenders or the Swingline Lender by the
Borrower or any of its representatives (the "Projections") have been or will
be prepared in good faith based upon assumptions the Borrower believes to be

     On the basis of a comprehensive review and assessment of the systems and

shall, and (as applicable) will cause each of the other Loan Parties to:

Section 7.1.  Corporate Existence; Compliance with Law; Etc.

     Except as not prohibited by this Agreement: (a) preserve and maintain
its existence, and all of its rights, privileges and franchises, including

(including rights to indemnification) under any Material Contracts, except in
each case, where the failure to do so would not have a Material Adverse
Effect.

Section 7.2.  Insurance

     Keep insured by financially sound and reputable insurers all property of
a character usually insured by entities engaged in the same or similar
business similarly situated against loss or damage of the kinds and in the
amounts customarily insured against by such businesses and carry such other
insurance as is usually carried by such businesses.  Without limiting the
obligations of the Borrower and the other Loan Parties under the foregoing
provisions of this Section, in the event the Borrower or any of the other
Loan Parties shall fail to maintain in full force and effect insurance as
required by the foregoing provisions of this Section or any of the other
Credit Documents, then the Agent, on behalf of the Lenders, may upon notice
to the Borrower or such other Loan Party, but shall have no obligation to,
procure insurance covering the interests of the Agent and the Lenders in such
amounts and against such risks as the Agent shall deem appropriate, and the
Borrower shall reimburse the Agent in respect of any premiums paid by the
Agent as provided in Section 12.2.

Section 7.3.  Obligations and Taxes

     Pay its Indebtedness and other obligations in accordance with their
terms and pay and discharge promptly all taxes, assessments and governmental
charges or levies imposed upon it or upon its income or profits or in respect
of its property, and in any event before the same shall become delinquent or
in default, as well as all lawful claims for labor, materials and supplies or
otherwise which, if unpaid, might give rise to a Lien upon such properties or
any part thereof which could reasonably be expected to have a Material
Adverse Effect; provided, however, that such payment and discharge shall not
be required so long as the validity or amount thereof shall be contested in
good faith by appropriate proceedings which effectively stay the execution of
any such Lien and the Borrower shall (or shall cause the applicable Loan
Party to) set aside on its books adequate reserves in accordance with GAAP
with respect thereto.

Section 7.4.  Maintaining Records; Access to Properties and Inspections

     Maintain all financial records in accordance with GAAP and permit any
representatives designated by the Agent or any Lender upon reasonable notice
to visit and inspect the properties of the Borrower or any of the other Loan
Parties (such visits and inspections to be at the sole cost and expense of
the Agent or such Lender, so long as an Event of Default is not existing) and
to inspect their financial and business records (except records and documents
subject to the attorney-client privilege and the work product doctrine) and
make extracts therefrom and copies thereof, all at reasonable times and in a
manner so as not to unreasonably disrupt the operations of the Borrower or
the other Loan Parties and as often as reasonably requested, and permit the
Agent or any Lender or any representatives designated by the Agent or any
Lender upon reasonable notice to discuss the affairs, finances and condition
of the Borrower or any of the other Loan Parties with the officers thereof
and independent accountants therefor; provided, however, that (i) any
representatives designated by the Agent or any Lender shall be in the
business of acting as crisis managers or business consultants and shall be
bound by the same or similar internal policies with regard to confidential
information as is the Agent or such Lender and (ii) the Agent or any Lender
or any representatives designated by the Agent or any Lender shall not
discuss the affairs, finances and condition of the Borrower or any of the
other Loan Parties with the Borrower's independent accountants unless and
until the Agent or such Lender determines in its reasonable discretion that
discussions directly with the Borrower or the officers of the Borrower have
failed to satisfy the inquiries of the Agent or such Lender or its
representatives.  Not in limitation of the foregoing, the Borrower shall, and
shall cause each of the other Loan Parties to, keep complete, accurate and
detailed financial records with respect to all amounts of all Loans made
available to any of the Subsidiaries by way of loans.

Section 7.5.  Environmental and Safety Matters

     For the purposes of protecting the Agent's security interest in the
Collateral and preserving the Borrower's ability to satisfy its Obligations:

     (a)  Comply with all Environmental and Safety Laws applicable to it or
any of its property or facilities in all material respects.

     (b)  Keep its properties and facilities free from any Liens arising
under any Environmental and Safety Laws which could reasonably be expected to
have a Material Adverse Effect.

     (c)  Respond promptly to any Release or threatened Release of any
Hazardous Materials in a manner which complies in all material respects with
all applicable Environmental and Safety Laws and mitigates any associated
risk to human health or the environment to the maximum extent commercially
practicable.

     (d)  If the Agent at any time has a reasonable basis to believe that any
property or facility owned or operated by the Borrower or any other Loan
Party has been or may be either (i) operated in violation of any applicable
Environmental and Safety Laws; (ii) contaminated with any Hazardous Materials
at or above levels requiring removal or remedial action under applicable
Environmental and Safety Laws; or (iii) subject to any government-imposed
obligation to conduct any environmental investigation or clean-up, any of
which, in the good faith judgment of the Agent may impair in any material
respect the value of the Collateral or the ability of the Borrower or any of
the other Loan Parties to satisfy any of their respective Obligations, the
Borrower shall, upon the written request of the Agent, at the Borrower's sole
cost and expense, conduct such investigation or study, through retention of a
consulting firm reasonably satisfactory to the Agent, as is necessary in the
good faith judgment of the Agent to demonstrate that no such impairment could
reasonably be expected to have a Material Adverse Effect.

Section 7.6.  Additional Security

     If and to the extent requested by the Agent or the Requisite Lenders
from time to time, after the occurrence and during the continuation of a
Default or Event of Default, execute and deliver such additional documents
and take such other action as may be necessary or desirable in the reasonable
opinion of the Agent or the Requisite Lenders, in order to assure and confirm
that all Obligations are secured in a manner acceptable to the Agent or the
Requisite Lenders by a first priority Lien on substantially all present and
future assets of the Borrower and the other Loan Parties (other than any
Foreign Subsidiary) subject only to Permitted Liens.

Section 7.7.  Use of Proceeds; Letters of Credit.

     Use the proceeds of all Loans and all Letters of Credit for working
capital, capital expenditures, and other lawful corporate purposes, including
permitted stock repurchases and permitted Acquisitions.  The Borrower shall
not, and shall not permit any Subsidiary or other Loan Party to, use any part
of such proceeds or Letters of Credit to purchase or carry, or to reduce or
retire or refinance any credit incurred to purchase or carry, any margin
stock (within the meaning of Regulation U of the Board of Governors of the
Federal Reserve System) or to extend credit to others for the purpose of
purchasing or carrying any such margin stock.

Section 7.8.  Additional Material Subsidiaries.

     Within 60 calendar days of any Person becoming a Subsidiary after the
Agreement Date, the Borrower shall deliver to the Agent each of the items
that would be required to be delivered under Section 5.3. if such Subsidiary
were a New Subsidiary being acquired pursuant to an Acquisition (but only to
the extent such items are not otherwise required to be delivered to the Agent
under such Section).  Notwithstanding any provision of this Agreement or any
other Loan Document, (a) no Foreign Subsidiary shall be required to execute
and deliver a Guaranty and (b) a Loan Party shall only be obligated to pledge
under the Pledge Agreement the maximum amount of the total combined voting
power of all classes of stock entitled to vote of its respective Foreign
Subsidiaries that it may so pledge without such Foreign Subsidiary being
deemed to be holding United States property by virtue of 26 C.F.R.
1.956-2(c)(2).

     Obligations, to be applied for the ratable benefit of the Lenders;

          (f)  payments of cash amounts to the Agent in respect of
     outstanding Letters of Credit pursuant to Section 2.11.;

          (g)  amounts due to the Agent and the Lenders pursuant to Sections
     12.9.;

          (h)  payments of all other amounts due under any of the Credit
     Documents, if any, to be applied for the ratable benefit of the Lenders;

          (i)  amounts due Lenders in respect of Swap Obligations, to be
     applied for the ratable benefit of such Lenders; and

          (j)  any amount remaining after application as provided above,
     shall be paid to the Borrower or whomever else may be legally entitled
     thereto.

Section 10.5.  Collateral Account.

     (a)  As collateral security for the prompt payment in full when due of
all Letter of Credit Liabilities, the Borrower hereby pledges and grants to
the Agent, for the benefit of the Agent and the Lenders as provided herein, a
security interest in all of its right, title and interest in and to the
Collateral Account and the balances from time to time in the Collateral
Account (including the investments and reinvestments therein provided for
below).  The balances from time to time in the Collateral Account shall not
constitute payment of any Letter of Credit Liabilities until applied by the
Agent as provided herein.  Anything in this Agreement to the contrary
notwithstanding, funds held in the Collateral Account shall be subject to
withdrawal only as provided in this Section and in Section 2.11.

     (b)  Amounts on deposit in the Collateral Account shall be invested and
reinvested by the Agent in such Cash Equivalents as the Agent shall determine
in its sole discretion.  All such investments and reinvestments shall be held
in the name of and be under the sole dominion and control of the Agent and
all interest and other earnings in respect of such investments and
reinvestments shall be deposited into the Collateral Account until withdrawn
as provided in this Section (including the immediately following
subsection (d)), in Section 2.11. or in any other applicable provision of
this Agreement or any other Credit Document.  The Agent shall exercise
reasonable care in the custody and preservation of any funds held in the
Collateral Account and shall be deemed to have exercised such care if such
funds are accorded treatment substantially equivalent to that which the Agent
accords its own funds, it being understood that the Agent shall not have any
responsibility for taking any necessary steps to preserve rights against any
parties with respect to any funds held in the Collateral Account.

     (c)  If an Event of Default shall have occurred and be continuing, the
Agent may (and, if instructed by the Requisite Lenders, shall) in its (or
their) discretion at any time and from time to time elect to liquidate any
such investments and reinvestments and credit the proceeds thereof to the
Collateral Account and apply or cause to be applied such proceeds and any
other balances in the Collateral Account to the payment of any of the Letter
of Credit Liabilities due and payable.

     (d)  So long as no Default or Event of Default has occurred and is
continuing, the Agent shall, from time to time, at the written request of the
Borrower, deliver to the Borrower within 5 days of receipt of such request,
against receipt but without any recourse, warranty or representation
whatsoever, such of the balances in the Collateral Account as exceed the
aggregate amount of Letter of Credit Liabilities at such time, including any
interest and other earnings on investments in respect of the Collateral
Account.  When all of the Obligations shall have been paid in full and no
Letters of Credit remain outstanding, the Agent shall promptly deliver to the
Borrower, against receipt but without any recourse, warranty or
representation whatsoever, the balances remaining in the Collateral Account.

Section 10.6.  Performance by Agent.

     If the Borrower shall fail to perform any covenant, duty or agreement
contained in any of the Credit Documents, the Agent may perform or attempt to
perform such covenant, duty or agreement on behalf of the Borrower after the
expiration of any cure or grace periods set forth herein.  In such event, the
Borrower shall, at the request of the Agent, promptly pay any amount
reasonably expended by the Agent in such performance or attempted performance
to the Agent, together with interest thereon at the applicable Post-Default
Rate from the date of such expenditure until paid.  Notwithstanding the
foregoing, neither the Agent nor any Lender shall have any liability or
responsibility whatsoever for the performance of any obligation of the
Borrower under this Agreement or any other Credit Document.

Section 10.7.  Rights Cumulative.

     The rights and remedies of the Agent and the Lenders under this
Agreement and each of the other Credit Documents shall be cumulative and not
exclusive of any rights or remedies which any of them may otherwise have
under Applicable Law.  In exercising their respective rights and remedies the
Agent and the Lenders may be selective and no failure or delay by the Agent
or any of the Lenders in exercising any right shall operate as a waiver of
it, nor shall any single or partial exercise of any power or right preclude
its other or further exercise or the exercise of any other power or right.

                                  ARTICLE XI. THE AGENT

Section 11.1.  Authorization and Action.

     Each Lender hereby appoints and authorizes the Agent to take such action
as contractual representative on such Lender's behalf and to exercise such
powers under this Agreement and the other Credit Documents as are
specifically delegated to the Agent by the terms hereof and thereof, together
with such powers as are reasonably incidental thereto.  Nothing herein shall
be construed to deem the Agent a trustee or fiduciary for any Lender nor to
impose on the Agent duties or obligations other than those expressly provided
for herein.  Not in limitation of the foregoing, each Lender confirms and
agrees that the Agent has no fiduciary obligations to such Lender under this
Agreement, any other Credit Document or otherwise.  At the request of a
Lender, the Agent will forward to such Lender copies or, where appropriate,
originals of the documents delivered to the Agent pursuant to this Agreement
or the other Credit Documents.  The Agent will also furnish to any Lender,
upon the request of such Lender, a copy of any certificate or notice
furnished to the Agent by the Borrower, any Loan Party or any other Affiliate
of the Borrower, pursuant to this Agreement or any other Credit Document not
already required to be delivered to such Lender pursuant to the terms of this
Agreement or any such other Credit Document.  As to any matters not expressly
provided for by the Credit Documents (including, without limitation,
enforcement or collection of any of the Obligations), the Agent shall not be
required to exercise any discretion or take any action, but shall be required
to act or to refrain from acting (and shall be fully protected in so acting
or refraining from acting) upon the instructions of the Requisite Lenders (or
all of the Lenders if explicitly required under any other provision of this
Agreement), and such instructions shall be binding upon all Lenders and all
holders of any of the Obligations; provided, however, that, notwithstanding
anything in this Agreement to the contrary, the Agent shall not be required
to take any action which exposes the Agent to personal liability or which is
contrary to this Agreement or any other Credit Document or Applicable Law.
Not in limitation of the foregoing, the Agent shall not exercise any right or
remedy it or the Lenders may have under any Credit Document upon the
occurrence of a Default or an Event of Default unless the Requisite Lenders
have so directed the Agent to exercise such right or remedy.

Section 11.2.  Agent's Reliance, Etc.

     Notwithstanding any other provisions of this Agreement or any other
Credit Documents, neither the Agent nor any of its directors, officers,
agents, employees or counsel shall be liable to any Lender for any action
taken or omitted to be taken by it or them under or in connection with this
Agreement, except to the extent found in a final, non-appealable judgment by
a court of competent jurisdiction to have resulted from its or their own
gross negligence or willful misconduct.  Without limiting the generality of
the foregoing, the Agent: (a) may treat the payee of any Note as the holder
thereof until the Agent receives written notice of the assignment or transfer
thereof signed by such payee and in form satisfactory to the Agent; (b) may
consult with legal counsel (including its own counsel or counsel for the
Borrower or any Loan Party), independent public accountants and other experts
selected by it and shall not be liable for any action taken or omitted to be
taken in good faith by it in accordance with the advice of such counsel,
accountants or experts; (c) makes no warranty or representation to any Lender
or any other Person and shall not be responsible to any Lender or any other
Person for any statements, warranties or representations made by any Person
in or in connection with this Agreement or any other Credit Document; (d)
shall not have any duty to ascertain or to inquire as to the performance or
observance of any of the terms, covenants or conditions of any of this
Agreement or any other Credit Document or the satisfaction of any conditions
precedent under this Agreement or any Credit Document on the part of the
Borrower or other Persons or inspect the property, books or records of the
Borrower or any other Person; (e) shall not be responsible to any Lender for
the due execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Agreement or any other Credit Document, any
other instrument or document furnished pursuant thereto or any Collateral
covered thereby or the perfection or priority of any Lien in favor of the
Agent on behalf of the Lenders in any such Collateral; and (f) shall incur no
liability under or in respect of this Agreement or any other Credit Document
by acting upon any notice, consent, certificate or other instrument or
writing (which may be by telephone or telecopy) believed by it to be genuine
and signed, sent or given by the proper party or parties.

Section 11.3.  Notice of Defaults.

     The Agent shall not be deemed to have knowledge or notice of the
occurrence of a Default or Event of Default unless the Agent has received notice
from a Lender or the Borrower referring to this Agreement, describing with
reasonable specificity such Default or Event of Default and stating that such
notice is a "notice of default."  If any Lender (excluding the Agent in its
capacity as a Lender) becomes aware of any Default or Event of Default, it
shall promptly send to the Agent such a "notice of defaul

Section 11.4.  Bank of America as Lender.

     Bank of America, as a Lender, shall have the same rights and powers
under this Agreement and any other Credit Document as any other Lender and
may exercise the same as though it were not the Agent; and the term "Lender"
or "Lenders" shall, unless otherwise expressly indicated, include Bank of
America in each case in its individual capacity.  Bank of America and its
affiliates may each accept deposits from, maintain deposits or credit
balances for, invest in, lend money to, act as trustee under indentures of,
serve as financial advisor to, and generally engage in any kind of business
with the Borrower, any other Loan Party or any other affiliate thereof as if
it were any other bank and without any duty to account therefor to the other
Lenders.  Further, the Agent and any affiliate may accept fees and other
consideration from the Borrower for services in connection with this
Agreement and otherwise without having to account for the same to the other
Lenders.

Section 11.5.  Approvals of Lenders.

     All communications from the Agent to any Lender requesting such Lender's
determination, consent, approval or disapproval (a) shall be given in the
form of a written notice to such Lender, (b) shall be accompanied by a
description of the matter or issue as to which such determination, approval,
consent or disapproval is requested, or shall advise such Lender where
information, if any, regarding such matter or issue may be inspected, or
shall otherwise describe the matter or issue to be resolved, (c) shall
include, if reasonably requested by such Lender and to the extent not
previously provided to such Lender, written materials provided to the Agent
by the Borrower in respect of the matter or issue to be resolved, and
(d) shall include the Agent's recommended course of action or determination
in respect thereof.  Each Lender shall reply promptly, but in any event
within 10 Business Days (or such lesser period as may be required under the
Credit Documents for the Agent to respond).  Unless a Lender shall give
written notice to the Agent that it consents to the recommendation or
determination of the Agent within the applicable time period for reply, such
Lender shall be deemed to have conclusively rejected or not consented to such
recommendation or determination.

Section 11.6.  Lender Credit Decision, Etc.

     Each Lender expressly acknowledges and agrees that neither the Agent,
BAS, nor any of their respective officers, directors, employees, agents,
counsel, attorneys-in-fact or other affiliates has made any representations
or warranties as to the financial condition, operations, creditworthiness,
solvency or other information concerning the business or affairs of the
Borrower, any other Loan Party, any Subsidiary or other Person to such Lender
and that no act by the Agent hereinafter taken, including any review of the
affairs of the Borrower, shall be deemed to constitute any such
representation or warranty by the Agent to any Lender.  Each Lender
acknowledges that it has, independently and without reliance upon the Agent,
BAS, any other Lender or counsel to the Agent, or any of their respective
officers, directors, employees and agents, and based on the financial
statements of the Borrower, the Subsidiaries or any other Affiliate thereof,
and inquiries of such Persons, its independent due diligence of the business
and affairs of the Borrower, the Loan Parties, the Subsidiaries and other
Persons, its review of the Credit Documents, the legal opinions required to
be delivered to it hereunder, the advice of its own counsel and such other
documents and information as it has deemed appropriate, made its own credit
and legal analysis and decision to enter into this Agreement and the
transaction contemplated hereby. Each Lender also acknowledges that it will,
independently and without reliance upon the Agent, BAS, any other Lender or
counsel to the Agent or any of their respective officers, directors,
employees and agents, and based on such review, advice, documents and
information as it shall deem appropriate at the time, continue to make its
own decisions in taking or not taking action under the Credit Documents.
Except for notices, reports and other documents and information expressly
required to be furnished to the Lenders by the Agent under this Agreement or
any of the other Credit Documents, the Agent shall have no duty or
responsibility to provide any Lender with any credit or other information
concerning the business, operations, property, financial and other condition
or creditworthiness of the Borrower, any other Loan Party or any other
Affiliate thereof which may come into possession of the Agent or any of its
officers, directors, employees, agents, attorneys-in-fact or other
Affiliates.  Each Lender acknowledges that the Agent's legal counsel in
connection with the transactions contemplated by this Agreement is only
acting as counsel to the Agent and is not acting as counsel to such Lender.

Section 11.7.  Indemnification of Agent.

     Each Lender agrees to indemnify the Agent (to the extent not reimbursed
by the Borrower and without limiting the obligation of the Borrower to do so)
pro rata in accordance with such Lender's respective Commitment Percentage,
from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever which may at any time be imposed on, incurred by,
or asserted against the Agent (in its capacity as Agent but not as a Lender)
in any way relating to or arising out of the Credit Documents, any
transaction contemplated hereby or thereby or any action taken or omitted by
the Agent under the Credit Documents (collectively, "Indemnifiable Amounts");
provided, however, that no Lender shall be liable for any portion of such
Indemnifiable Amounts to the extent found in a final non-appealable judgment
by a court of competent jurisdiction to have resulted from the Agent's gross
negligence or willful misconduct.  Without limiting the generality of the
foregoing, each Lender agrees to reimburse the Agent promptly upon demand for
its ratable share of any out-of-pocket expenses (including reasonable counsel
fees of the counsel(s) of the Agent's own choosing) incurred by the Agent in
connection with the preparation, execution, administration, or enforcement
of, or legal advice with respect to the rights or responsibilities of the
parties under, the Credit Documents, any suit or action brought by the Agent
to enforce the terms of the Credit Documents and/or collect any Obligations,
any "lender liability" suit or claim brought against the Agent and/or the
Lenders, and any claim or suit brought against the Agent and/or the Lenders
arising under any Environmental and Safety Laws, to the extent that the Agent
is not reimbursed for such expenses by the Borrower. The agreements in this
Section shall survive the payment of the Loans and all other amounts payable
hereunder or under the other Credit Documents, the expiration of all Letters
of Credit and the termination of this Agreement.  If the Borrower shall
reimburse the Agent for any Indemnifiable Amount following payment by any
Lender to the Agent in respect of such Indemnifiable Amount pursuant to this
Section, the Agent shall share such reimbursement on a ratable basis with
each Lender making any such payment.

Section 11.8.  Collateral Matters.

     (a)  The Agent is authorized on behalf of all of the Lenders, without
the necessity of any notice to or further consent from any Lender, from time
to time prior to an Event of Default, to take any action with respect to any
Collateral or Credit Documents which may be necessary to perfect and maintain
perfected the Liens upon the Collateral granted pursuant to any of the Credit
Documents.

     (b)  The Lenders hereby authorize the Agent, at its option and in its
discretion, to release any Lien granted to or held by the Agent upon any
Collateral (i) upon termination of the Commitments and payment and
satisfaction of all of the Obligations at any time arising under or in
respect of this Agreement or the Credit Documents or the transactions
contemplated hereby or thereby; (ii) constituting property being sold or
disposed of if the Borrower certifies to the Agent that the sale or
disposition is made in compliance with Section 9.9. (and the Agent may rely
conclusively on any such certificate, without further inquiry), including
without limitation, any sale or disposition of any of the Collateral in
connection with the Seramed Disposition; (iii) as permitted by, but only in
accordance with, the express terms of the applicable Credit Document; or
(iv) if approved, authorized or ratified in writing by all of the Lenders
hereunder.  Upon request by the Agent at any time, the Lenders will confirm
in writing the Agent's authority to release particular types or items of
Collateral pursuant to this Section.

     (c)  Upon any sale and transfer of Collateral which is expressly
permitted pursuant to the terms of this Agreement, or consented to in writing
by the Requisite Lenders or all of the Lenders, as applicable, and upon at
least five Business Days' prior written request by the Borrower, the Agent
shall (and is hereby irrevocably authorized by the Lenders to) execute such
documents as may be necessary to evidence the release of the Liens granted to
the Agent for the benefit of the Lenders herein or pursuant hereto upon the
Collateral that was sold or transferred; provided, however, that (i) the
Agent shall not be required to execute any such document on terms which, in
the Agent's opinion, would expose the Agent to liability or create any
obligation or entail any consequence other than the release of such Liens
without recourse or warranty; and (ii) such release shall not in any manner
discharge, affect or impair the Obligations or any Liens upon (or obligations
of the Borrower or any Loan Party in respect of) all interests retained by
the Borrower or any Subsidiary, including (without limitation) the proceeds
of the sale, all of which shall continue to constitute part of the
Collateral.  In the event of any sale or transfer of Collateral, or any
foreclosure with respect to any of the Collateral, the Agent shall be
authorized to deduct all of the expenses reasonably incurred by the Agent
from the proceeds of any such sale, transfer or foreclosure.

     (d)  The Agent shall have no obligation whatsoever to the Lenders or to
any other Person to assure that the Collateral exists or is owned by the
Borrower or any Subsidiary or is cared for, protected or insured or that the
Liens granted to the Agent herein or pursuant hereto have been properly or
sufficiently or lawfully created, perfected, protected or enforced or are
entitled to any particular priority, or to exercise or to continue exercising
at all or in any manner or under any duty of care, disclosure or fidelity any
of the rights, authorities and powers granted or available to the Agent in
this Section or in any of the Credit Documents, it being understood and
agreed that in respect of the Collateral, or any act, omission or event
related thereto, the Agent may act in any manner it may deem appropriate, in
its sole discretion, given the Agent's own interest in the Collateral as one
of the Lenders and that the Agent shall have no duty or liability whatsoever
to the Lenders, except for its gross negligence or willful misconduct.

Section 11.9.  Successor Agent.

     The Agent may resign at any time as Agent under the Credit Documents by
giving written notice thereof to the Lenders and the Borrower.  Upon any such
resignation, the Requisite Lenders shall have the right to appoint a
successor Agent which appointment shall, provided no Default or Event of
Default shall have occurred and be continuing, be subject to the Borrower's
approval, which approval shall not be unreasonably withheld or delayed
(except that Borrower shall, in all events, be deemed to have approved each
Lender as a successor Agent).  If no successor Agent shall have been so
appointed by the Requisite Lenders, and shall have accepted such appointment,
within 30 days after the resigning Agent's giving of notice of resignation,
then the resigning Agent may, on behalf of the Lenders, appoint a successor
Agent, which shall be a Lender, if any Lender shall be willing to serve, and
otherwise shall be a commercial bank having total combined assets of at least
$50,000,000,000.  Upon the acceptance of any appointment as Agent hereunder
by a successor Agent, such successor Agent shall thereupon succeed to and
become vested with all the rights, powers, privileges and duties of the
resigning Agent, and the resigning Agent shall be discharged from its duties
and obligations under the Credit Documents.  After any resigning Agent's
resignation hereunder as 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 Agent under the Credit Documents.

Section 11.10.  Co-Agents.

     The Co-Agents in such capacity assume no responsibility or obligation
hereunder, including, without limitation, for servicing, enforcement or
collection of any of the Loans, nor any duties as an agent hereunder for the
Lenders.  The title of "Co-Agent" is solely honorific and implies no
fiduciary responsibility on the part of either Co-Agent, in its capacity as
such, to the Agent, the Borrower or any Lender and the use of such title does
not impose on either Co-Agent any duties or obligations greater than those of
any other Lender or entitle either Co-Agent to any rights other than those to
which any other Lender is entitled.

Section 12.3.  Setoff.

     Subject to Section 3.3., the Borrower hereby authorizes the Agent and
each Lender (subject to receipt by such Lender of the Agent's prior written
consent) at any time while an Event of Default exists, to the fullest extent
permitted by Applicable Law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held,

SUCH AS (BUT NOT LIMITED TO) SETOFF, OR (B) TO FORECLOSE AGAINST ANY REAL OR
PERSONAL PROPERTY COLLATERAL, OR (C) TO OBTAIN FROM A COURT PROVISIONAL OR
ANCILLARY REMEDIES SUCH AS (BUT NOT LIMITED TO) INJUNCTIVE RELIEF, WRIT OF
POSSESSION OR THE APPOINTMENT OF A RECEIVER.  THE AGENT AND THE LENDERS MAY
EXERCISE SUCH SELF HELP RIGHTS, FORECLOSE UPON SUCH PROPERTY, OR OBTAIN SUCH
PROVISIONAL OR ANCILLARY REMEDIES BEFORE, DURING OR AFTER THE PENDENCY OF ANY
ARBITRATION PROCEEDING BROUGHT PURSUANT TO THIS AGREEMENT.  NEITHER THE
EXERCISE OF SELF HELP REMEDIES NOR THE INSTITUTION OR MAINTENANCE OF AN
ACTION FOR FORECLOSURE OR PROVISIONAL OR ANCILLARY REMEDIES SHALL CONSTITUTE
A WAIVER OF THE RIGHT OF ANY PARTY, INCLUDING THE CLAIMANT IN ANY SUCH
ACTION, TO ARBITRATE THE MERITS OF THE CONTROVERSY OR CLAIM OCCASIONING
RESORT TO SUCH REMEDIES.

Section 12.5.  Successors and Assigns.

     (a)  The provisions of this Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and
permitted assigns, except that the Borrower may not assign or otherwise
transfer any of its rights under this Agreement without the prior written
consent of all Lenders.

     (b)  Any Lender may make, carry or transfer Loans at, to or for the
account of, any of its branch offices or the office of an affiliate of such
Lender except to the extent such transfer would result in increased costs to
the Borrower.

     (c)  Any Lender may at any time grant to one or more banks or other
financial institutions (each a "Participant") participating interests in its
Commitment or the Obligations owing to such Lender; provided, however, any
such participating interest must be for a constant and not a varying
percentage interest.  No Participant shall have any rights or benefits under
this Agreement or any other Credit Document.  In the event of any such grant
by a Lender of a participating interest to a Participant, such Lender shall
remain responsible for the performance of its obligations hereunder, and the
Borrower and the Agent shall continue to deal solely and directly with such
Lender in connection with such Lender's rights and obligations under this
Agreement.  Any agreement pursuant to which any Lender may grant such a
participating interest shall provide that such Lender shall retain the sole
right and responsibility to enforce the obligations of the Borrower hereunder
including, without limitation, the right to approve any amendment,
modification or waiver of any provision of this Agreement; provided, however,
such Lender may agree with the Participant that it will not, without the
consent of the Participant, agree to (i) increase, or extend the term or
extend the time or waive any requirement for the reduction or termination of,
such Lender's Commitment, (ii) extend the date fixed for the payment of
principal of or interest on the Loans or portions thereof owing to such
Lender, (iii) reduce the amount of any such payment of principal, (iv) reduce
the rate at which interest is payable thereon (v) any release of all or
substantially all of the Collateral; or (vi) any release of any Guarantor
from its obligations under the Guaranty.  An assignment or other transfer
which is not permitted by subsection (d) below shall be given effect for
purposes of this Agreement only to the extent of a participating interest
granted in accordance with this subsection (c).  The selling Lender shall
notify the Agent and the Borrower of the sale of any participation hereunder
and the terms thereof.

     (d)  Any Lender may with the prior written consent of the Agent and the
Borrower (which consent, in each case, shall not be unreasonably withheld)
assign to one or more Eligible Assignees (each an "Assignee") all or a
portion of such Lender's Commitment and its other rights, obligations and
rights and obligations under this Agreement and the Notes; provided, however,
(i) no such consent by the Borrower shall be required in any case if a
Default or Event of Default shall have occurred and be continuing; (ii) no
such consent by the Borrower shall be required in the case of any assignment
to another Lender or any affiliate of such Lender or another Lender unless
after giving effect to such assignment, the Assignee will hold 40% or more of
the aggregate amount of all Lenders' Commitments; (iii) any partial
assignment shall be in an amount at least equal to $5,000,000 and after
giving effect to such assignment the assigning Lender retains a Commitment,
or if the Commitments have been terminated, holds Notes having an aggregate
outstanding principal balance, of at least $5,000,000; and (iv) each such
assignment shall be effected by means of an Assignment and Acceptance
Agreement.  Upon execution and delivery of such instrument and payment by
such Assignee to such transferor Lender of an amount equal to the purchase
price agreed between such transferor Lender and such Assignee, such Assignee
shall be deemed to be a Lender party to this Agreement as of the effective
date of the Assignment and Acceptance Agreement and shall have all the rights
and obligations of a Lender with a Commitment as set forth in such Assignment
and Acceptance Agreement, and the transferor Lender shall be released from
its obligations hereunder to a corresponding extent, and no further consent
or action by any party shall be required.  Upon the consummation of any
assignment pursuant to this subsection (d), the transferor Lender, the Agent
and the Borrower shall make appropriate arrangements so that new Notes are
issued to the Assignee and such transferor Lender, as appropriate.  In
connection with any such assignment (including without limitation, an
assignment from one Lender to another Lender), the transferor Lender shall
pay to the Agent an administrative fee for processing such assignment in the
amount of $3,500.

     (e)  The Agent shall maintain at the Principal Office a copy of each
Assignment and Acceptance Agreement delivered to and accepted by it and a
register for the recordation of the names and addresses of the Lenders and
the Commitment of each Lender from time to time (the "Register").  The Agent
shall give each Lender and the Borrower notice of the assignment by any
Lender of its rights as contemplated by this Section.  The Borrower, the
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 and copies of each Assignment and Acceptance Agreement shall be
available for inspection by the Borrower or any Lender at any reasonable time
and from time to time upon reasonable prior notice to the Agent.  Upon its
receipt of an Assignment and Acceptance Agreement executed by an assigning
Lender, together with each Note subject to such assignment, the Agent shall,
if such Assignment and Acceptance Agreement has been completed and if the
Agent receives the processing and recording fee described in subsection (d)
above, (i) accept such Assignment and Acceptance Agreement, (ii) record the
information contained therein in the Register and (iii) give prompt notice
thereof to the Borrower.

     (f)  In addition to the assignments and participations permitted under
the foregoing provisions of this Section, any Lender may assign and pledge
all or any portion of its Loans and its Notes to any Federal Reserve Bank as
collateral security pursuant to Regulation A and any Operating Circular
issued by such Federal Reserve Bank, and such Loans and Notes shall be fully
transferable as provided therein.  No such assignment shall release the
assigning Lender from its obligations hereunder.

     (g)  A Lender may furnish any information concerning the Borrower, any
other Loan Party or any of their respective Subsidiaries in the possession of
such Lender from time to time to Assignees and Participants (including
prospective Assignees and Participants) subject to compliance with Section
12.8.

     (h)  Anything in this Section to the contrary notwithstanding, no Lender
may assign or participate any interest in any Loan held by it hereunder to
the Borrower, any other Loan Party or any of their respective Affiliates or
Subsidiaries.

     (i)  Each Lender agrees that, without the prior written consent of the
Borrower and the Agent, it will not make any assignment hereunder in any
manner or under any circumstances that would require registration or
qualification of, or filings in respect of, any Loan or Note under the
Securities Act or any other securities laws United States of America or of
any other jurisdiction.

Section 12.6.  Amendments.

     Except as otherwise expressly provided in this Agreement, any consent or
approval required or permitted by this Agreement or in any Credit Document to
be given by the Lenders may be given, and any term of this Agreement or of
any other Credit Document may be amended, and the performance or observance
by the Borrower or any Loan Party or Subsidiary of any terms of this
Agreement or such other Credit Document or the continuance of any Default or
Event of Default may be waived (either generally or in a particular instance
and either retroactively or prospectively) with, but only with, the written
consent of the Requisite Lenders (and, in the case of an amendment to any
Credit Document, the written consent of the Borrower).  Notwithstanding the
foregoing, no amendment, waiver or consent shall, unless in writing, and
signed by all of the Lenders (or the Agent at the written direction of the
Lenders), do any of the following: (i) increase the Commitments of the
Lenders or subject the Lenders to any additional obligations; (ii) reduce the
principal of, or interest rates that have accrued or that will be charged on
the outstanding principal amount of, any Loans or other Obligations;
(iii) reduce the amount of any Fees payable hereunder; (iv) postpone any date
fixed for any payment of any principal of, interest on, or Fees with respect
to, any Loans or any other Obligations; (v) change the Commitment
Percentages; (vi) amend this Section or amend the definitions of the terms
used in this Agreement or the other Credit Documents insofar as such
definitions affect the substance of this Section; (vii) modify the definition
of the term "Requisite Lenders" or modify in any other manner the number or
percentage of the Lenders required to make any determinations or waive any
rights hereunder or to modify any provision hereof; and (viii) release any
Guarantor from its obligations under the Guaranty.  Any amendment, waiver or
consent relating to Section 2.12. or the obligations of Swingline Lender
under this Agreement or any other Loan Document shall, in addition to Lenders
required hereinabove to take such action, require the written consent of
Swingline Lender.  Further, no amendment, waiver or consent unless in writing
and signed by the Agent, in addition to the Lenders required hereinabove to
take such action, shall affect the rights or duties of the Agent under this
Agreement or any of the other Credit Documents.  Further, no Collateral shall
be released or disposed of by the Agent unless all of the Lenders so direct
the Agent or unless released or disposed of as permitted by, and in
accordance with, Section 11.8.  No waiver shall extend to or affect any
obligation not expressly waived or impair any right consequent thereon and
any amendment, waiver or consent shall be effective only in the specific
instance and for the specific purpose set forth therein.  No course of
dealing or delay or omission on the part of the Agent or any Lender in
exercising any right shall operate as a waiver thereof or otherwise be
prejudicial thereto.  Except as otherwise explicitly provided for herein or
in any other Credit Document, no notice to or demand upon the Borrower shall
entitle the Borrower to other or further notice or demand in similar or other
circumstances.

Section 12.7.  Nonliability of Agent and Lenders.

     The relationship between the Borrower, on the one hand, and the Lenders
and the Agent, on the other hand, shall be solely that of borrower and
lender.  Neither the Agent nor any Lender shall have any fiduciary
responsibilities to the Borrower and no provision in this Agreement or in any
of the other Credit Documents, and no course of dealing between or among any
of the parties hereto, shall be deemed to create any fiduciary duty owing by
the Agent or any Lender to any Lender, the Borrower, any Subsidiary or any
other Loan Party.  Neither the Agent nor any Lender undertakes any
responsibility to the Borrower to review or inform the Borrower of any matter
in connection with any phase of the Borrower's business or operations.

Section 12.8.  Confidentiality.

     The Agent and the Lenders shall hold all non-public, proprietary or
confidential information (which has been identified as such by the Borrower)
obtained pursuant to the requirements of this Agreement in accordance with
their customary procedures for handling confidential information of this
nature and in accordance with safe and sound banking practices; provided,
however, the Agent and the Lenders may make disclosure of any such
information to such of their examiners, affiliates, outside auditors,
counsel, consultants, appraisers and other professional advisors as may be
reasonably necessary in connection with this Agreement or as reasonably
required by any proposed Assignee or any proposed Participant in connection
with the contemplated transfer of any Note or participation therein or as
required or requested by any Governmental Authority or representative thereof
or in connection with the enforcement hereof or of any Loan Document or
related document or pursuant to legal process or with respect to any
litigation between or among the Borrower, the Agent, any of the Lenders or
the Swingline Lender; provided, however, that, as a condition to receipt of
any such information, each such affiliate, auditor, counsel, consultant,
appraiser, professional advisor, proposed Assignee or Participant shall agree
in writing to treat all such information as confidential; and provided,
further, that prior to any such disclosure to any unrelated entity outside
the ordinary course of business or pursuant to legal process, the party
making such disclosure shall give notice of such disclosure to the Borrower
and cooperate with the Borrower in any efforts to limit or restrict such
disclosure.  In no event shall the Agent, any Lender or the Swingline Lender
be obligated or required to return any materials furnished to it by the
Borrower.  The foregoing provisions shall not apply to the Agent, any Lender
or the Swingline Lender with respect to information that (a) is or becomes
generally available to the public (other than through such Person), (b) is
already in the possession of such Person on a nonconfidential basis, or
(c) comes into the possession of such Person in a manner not known to such
Person to involve a breach of a duty of confidentiality owing to the
Borrower.

Section 12.9.  Indemnification.

     The Borrower shall and hereby agrees to indemnify and defend the Agent,
BAS, any affiliate of the Agent and each of the Lenders and their respective
directors, officers, shareholders, agents, employees and counsel (each

harmless against, any and all losses, liabilities, claims (including
Environmental Claims), damages or expenses incurred by any of them arising
out of or by reason of any investigation or litigation or other proceedings

relating to the extensions of credit hereunder or any actual or proposed use
by the Borrower or any Loan Party of the proceeds of any of the extensions of
credit hereunder or the past, present or future business activities of the
Borrower or any Loan Party including, without limitation, the reasonable fees
and disbursements of counsel incurred in connection with any such
investigation or litigation or other proceedings (but excluding any such
losses, liabilities, claims, damages or expenses that are determined pursuant
to a final, non-appealable order of a court of competent jurisdiction or by
binding arbitration, as applicable, to have resulted solely from the gross
negligence, willful misconduct or bad faith of such Indemnified Party).

Section 12.10.  Survival.

     Notwithstanding any termination of this Agreement, or of the other
Credit Documents, the indemnities to which the Agent and the Lenders are
entitled under the provisions of Sections 11.7., 12.2. and 12.9. and any
other provision of this Agreement and the other Credit Documents, and the
arbitration provisions contained in Section 12.4., shall continue in full
force and effect and shall protect the protect the Agent, the Lenders and the
Swingline Lender against events arising after such termination as well as
before.

extent of such prohibition or unenforceability without invalidating the
remainder of such provision or the remaining provisions or affecting the
validity or enforceability of such provision in any other jurisdiction.

     THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF GEORGIA APPLICABLE TO CONTRACTS EXECUTED, AND TO BE
FULLY PERFORMED, IN SUCH STATE.

deemed an original, but all of which counterparts together shall constitute
but one and the same instrument.

Section 12.14.  Obligations with Respect to Loan Parties.

     The obligations of the Borrower to direct or prohibit the taking of
certain actions by the other Loan Parties as specified herein shall be
absolute and not subject to any defense the Borrower may have that the
Borrower does not control such Loan Parties.

Section 12.15.  Entire Agreement.

     This Agreement, the Notes, and the other Credit Documents referred to
herein, together with any letter agreement between the Agent, BAS, any Lender
or the Swingline Lender regarding Fees and any letter agreement between the
