            SECTION 2.1. GENERAL DESCRIPTION OF FACILITIES. Subject to and upon
the terms and conditions herein set forth, (a) the Lenders hereby establish in
favor of the Borrower a revolving credit facility pursuant to which the Lenders
severally agree (to the extent of each Lender's Pro Rata Share up to such
Lender's Revolving Commitment) to make Revolving Loans to the Borrower in

                                       25

<PAGE>

Loans pursuant to the terms and conditions hereof; provided, that in no event
shall the aggregate principal amount of all outstanding Revolving Loans,
Swingline Loans and outstanding LC Obligations exceed at any time the Aggregate
Revolving Commitments from time to time in effect.

            SECTION 2.2. REVOLVING LOANS. Subject to the terms and conditions
set forth herein, each Lender severally agrees to make Revolving Loans to the
Borrower from time to time on any Business Day during the Availability Period,
in an aggregate principal amount outstanding at any time that will not result in
(a) such Lender's Revolving Credit Exposure exceeding such Lender's Revolving
Commitment or (b) the sum of the aggregate Revolving Credit Exposures of all
Lenders exceeding the Aggregate Revolving Commitments. During the Availability
Period, the Borrower shall be entitled to borrow, prepay and reborrow Revolving
Loans in accordance with the terms and conditions of this Agreement.

            SECTION 2.3. PROCEDURE FOR REVOLVING BORROWINGS. the Borrower shall
give the Administrative Agent written notice (or telephonic notice promptly
confirmed in writing) of each Revolving Borrowing substantially in the form of
Exhibit 2.3 attached hereto (a "NOTICE OF REVOLVING BORROWING") (i) prior to
11:00 a.m. (Atlanta, Georgia time) one Business Day prior to the requested date
of each Base Rate Borrowing and (ii) prior to 11:00 a.m. (Atlanta, Georgia time)
three Business Days prior to the requested date of each Eurodollar Borrowing.
Each Notice of Revolving Borrowing shall be irrevocable and shall specify: (i)
the aggregate principal amount of such Borrowing, (ii) the date of such
Borrowing (which shall be a Business Day), (iii) the Type of such Revolving Loan
comprising such Borrowing, and (iv) in the case of a Eurodollar Borrowing, the
duration of the initial Interest Period applicable thereto (subject to the
provisions of the definition of Interest Period). Each Revolving Borrowing shall
consist entirely of Base Rate Loans or Eurodollar Loans, as the Borrower may
request. The aggregate principal amount of each Eurodollar Borrowing shall be
not less than $1,000,000 or a larger multiple of $500,000, and the aggregate
principal amount of each Base Rate Borrowing shall not be less than $500,000 or
a larger multiple of $100,000; provided, that Base Rate Loans made pursuant to
Section 2.5 or Section 2.26(e) may be made in lesser amounts as provided
therein. At no time shall the total number of Eurodollar Borrowings outstanding
at any time exceed six. Promptly following the receipt of a Notice of Revolving
Borrowing in accordance herewith, the Administrative Agent shall advise each
Lender of the details thereof and the amount of such Lender's Revolving Loan to
be made as part of the requested Revolving Borrowing.

            SECTION 2.4. SWINGLINE COMMITMENT. Subject to the terms and
conditions set forth herein, the Swingline Lender agrees to make Swingline Loans
to the Borrower, from time to time from the Closing Date to the Swingline
Termination Date, in an aggregate principal amount outstanding at any time not
to exceed the lesser of (a) the Swingline Commitment then in effect and (b) the
difference between the Aggregate Revolving Commitments and the aggregate
Revolving Credit Exposures of all Lenders; provided, that the Swingline Lender
shall not be required to make a Swingline Loan to refinance an outstanding
Swingline Loan. The Borrower shall be entitled to

                                       26

<PAGE>

borrow, repay and reborrow Swingline Loans in accordance with the terms and
conditions of this Agreement. Notwithstanding anything herein to the contrary,
the Borrower is under no obligation to accept any offer by the Swingline Lender
to make a Swingline Loan, and the Swingline Lender is under no obligation
whatsoever to offer to make a Swingline Loan to the Borrower.

            SECTION 2.5. PROCEDURE FOR SWINGLINE BORROWING; ETC. (a) the
Borrower shall give the Administrative Agent written notice (or telephonic
notice promptly confirmed in writing) of each Swingline Borrowing substantially
in the form of Exhibit 2.5 attached hereto ("NOTICE OF SWINGLINE BORROWING")
prior to 11:00 a.m. (Atlanta, Georgia time) on the requested date of each
Swingline Borrowing. Each Notice of Swingline Borrowing shall be irrevocable and
shall specify: (i) the principal amount of such Swingline Loan, (ii) the date of
such Swingline Loan (which shall be a Business Day) and (iii) the account to
which the proceeds of such Swingline Loan should be credited. The Administrative
Agent will promptly advise the Swingline Lender of each Notice of Swingline
Borrowing. Each Swingline Loan shall accrue interest at the Swingline Rate and
shall have an Interest Period (subject to the definition thereof) as agreed
between the Borrower and the Swingline Lender. The aggregate principal amount of
each Swingline Loan shall be not less than $500,000 or a larger multiple of
$100,000, or such other minimum amounts agreed to by the Swingline Lender and
the Borrower. The Swingline Lender will make the proceeds of each Swingline Loan
available to the Borrower in Dollars in immediately available funds at the
account specified by the Borrower in the applicable Notice of Swingline
Borrowing not later than 3:00 p.m. (Atlanta, Georgia time) on the requested date
of such Swingline Loan. The Administrative Agent will notify the Lenders on a
quarterly basis if any Swingline Loans occurred during such quarter.

            (b) If (i) any Swingline Loan matures and remains unpaid; (ii) any
Default or Event of Default occurs or (iii) the Swingline Lender's total amount
of outstanding aggregate Revolving Credit Exposures and Swingline Loans exceed
the Swingline Lender's Revolving Commitment, the Swingline Lender may, on behalf
of the Borrower (which hereby irrevocably authorizes and directs the Swingline
Lender to act on its behalf), give a Notice of Revolving Borrowing to the
Administrative Agent requesting the Lenders (including the Swingline Lender) to
make Base Rate Loans in an amount equal to the unpaid principal amount of any
Swingline Loan. Each Lender will make the proceeds of its Base Rate Loan
included in such Borrowing available to the Administrative Agent for the account
of the Swingline Lender in accordance with Section 2.9, which will be used
solely for the repayment of such Swingline Loan.

            (c) If for any reason a Base Rate Borrowing may not be (as
determined in the sole discretion of the Administrative Agent), or is not, made
in accordance with the foregoing provisions, then each Lender (other than the
Swingline Lender) shall purchase an undivided participating interest in such
Swingline Loan in an amount equal to its Pro Rata Share thereof on the date that
such Base Rate Borrowing should have occurred. On the date of such required
purchase, each Lender shall promptly transfer, in immediately available funds,
the amount of its participating interest to the Administrative Agent for the
account of the Swingline Lender. If such Swingline Loan bears interest at a rate
other than the Base Rate, such Swingline Loan shall automatically become a Base
Rate Loan on the effective date of any such participation and interest shall
become payable on demand.

                                       27

<PAGE>

            (d) Each Lender's obligation to make a Base Rate Loan pursuant to
Section 2.5(b) or to purchase the participating interests pursuant to Section
2.5(c) shall be absolute and unconditional and shall not be affected by any
circumstance, including without limitation (i) any setoff, counterclaim,
recoupment, defense or other right that such Lender or any other Person may have
or claim against the Swingline Lender, the Borrower or any other Person for any
reason whatsoever, (ii) the existence of a Default or an Event of Default or the
termination of any Lender's Revolving Commitment, (iii) the existence (or
alleged existence) of any event or condition which has had or could reasonably
be expected to have a Material Adverse Effect, (iv) any breach of this Agreement
or any other Loan Document by the Borrower, the Administrative Agent or any
Lender 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. Until such time as such Lender makes its required payment,
the Swingline Lender shall be deemed to continue to have outstanding Swingline
Loans in the amount of the unpaid participation for all purposes of the Loan
Documents. In addition, 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 the amount of such Lender's
participation interest in such Swingline Loans that such Lender failed to fund
pursuant to this Section, until such amount has been purchased in full.

            SECTION 2.6. INCREASE OF REVOLVING COMMITMENTS.

            (a) Upon the Canadian Sale and Prepayment Event, the Aggregate
Revolving Commitments shall be increased by $15,000,000 (the "Additional
Revolving Commitment Amount"). No less than ten days prior to the consummation
of the Canadian Sale and Prepayment Event, the Borrower shall give written
notice to the Administrative Agent (who shall promptly notify the Lenders
thereof) of the date that the Canadian Sale and Prepayment Event will be
effective. On the effective date of the Canadian Sale and Prepayment Event, so
long as no Default or Event of Default has occurred and is then continuing, each
Canadian Lender (or an Affiliate thereof designated by such Canadian Lender who
becomes a party to this Agreement and is otherwise reasonably acceptable to the
Borrower and the Administrative Agent (such Affiliate, an "Approved Affiliate"))
shall be deemed to have increased its Revolving Commitment by a principal amount
equal to its Canadian Pro Rata Share of the Additional Revolving Commitment
Amount. No Lender (other than the Canadian Lenders (or Approved Affiliates))
shall have any obligation to increase its Revolving Commitment or its other
obligations under this Agreement and the other Loan Documents.

            (b) An increase in the Aggregate Revolving Commitments pursuant to
this Section shall become effective as and when provided in subsection (a)
above. The Canadian Lenders (or Approved Affiliates) agree to enter into an
agreement in form and substance satisfactory to the Administrative Agent setting
forth the new Revolving Commitments of such Canadian Lenders (or Approved
Affiliate) and Annex I shall automatically be deemed amended to reflect the
Revolving Commitments of all Lenders after giving effect to the addition of such
Revolving Commitments.

                                       28

<PAGE>

            (c) Upon any increase in the aggregate amount of the Revolving
Commitments pursuant to this Section, within five Business Days, in the case of
any Base Rate Loans then outstanding, and at the end of the then current
Interest Period with respect thereto, in the case of any Eurodollar Loans then
outstanding, the Borrower shall prepay such Loans in their entirety and, the
Borrower shall reborrow Loans from the Lenders in proportion to their respective
Revolving Commitments after giving effect to such increase, until such time as
all outstanding Loans are held by the Lenders in such proportion.

            SECTION 2.7. [RESERVED.].

            SECTION 2.8. [RESERVED.]

            SECTION 2.9. FUNDING OF BORROWINGS.

            (a) Each Lender will make available each Borrowing in Dollars of
Revolving Loans to be made by it hereunder on the proposed date thereof by wire
transfer in immediately available funds by 11:00 a.m. (Atlanta, Georgia time) to
the Administrative Agent at the Payment Office. Swingline Loans will be made as
set forth in Section 2.5. The Administrative Agent will make such Loans
available to the Borrower by promptly crediting the amounts that it receives, in
like funds by the close of business on such proposed date, to an account
maintained with the Administrative Agent or, at the Borrower's option, by
effecting a wire transfer of such amounts to an account designated by the
Borrower to the Administrative Agent.

            (b) Unless the Administrative Agent shall have been notified by any
Lender prior to 3:00 p.m. (Atlanta, Georgia time) one Business Day prior to the
date of a Borrowing in which such Lender is participating that such Lender will
not make available to the Administrative Agent such Lender's share of such
Borrowing, the Administrative Agent may assume that such Lender has made such
amount available to the Administrative Agent on such date, and the
Administrative Agent, in reliance on such assumption, may make available to the
Borrower on such date a corresponding amount. If such corresponding amount is
not in fact made available to the Administrative Agent by such Lender on the
date of such Borrowing, the Administrative Agent shall be entitled to recover
such corresponding amount on demand from such Lender together with interest at a
rate per annum equal to the Administrative Agent's cost of funds for such amount
for up to two days and thereafter at the rate specified for such Borrowing. If
such Lender does not pay such corresponding amount forthwith upon the
Administrative Agent's demand therefor and the Administrative Agent has made the
amount of such Borrowing available to the Borrower, the Administrative Agent
shall promptly notify the Borrower, and the Borrower shall immediately pay such
corresponding amount to the Administrative Agent together with interest at the
rate specified for such Borrowing. Nothing in this subsection shall be deemed to
relieve any Lender from its obligation to fund its Pro Rata Share of any
Borrowing hereunder or to prejudice any rights which the Borrower may have
against any Lender as a result of any default by such Lender hereunder.

            (c) All Revolving Loans shall be made by the Lenders on the basis of
their respective Pro Rata Shares. No Lender shall be responsible for any default
by any other Lender in its

                                       29

<PAGE>

obligations hereunder, and each Lender shall be obligated to make its Loans
provided to be made by it hereunder, regardless of the failure of any other
Lender to make its Loans hereunder.

            SECTION 2.10. INTEREST ELECTIONS; CONVERSIONS; CONTINUATIONS.

            (a) Each Borrowing initially shall be of the Type specified in the
applicable Notice of Borrowing, and in the case of a Eurodollar Borrowing, shall
have an initial Interest Period as specified in such Notice of Borrowing.
Thereafter, the Borrower may elect to convert such Borrowing into a different
Type or to continue such Borrowing (subject to satisfaction of any conditions
applicable to Borrowings of that Type), and in the case of a Eurodollar
Borrowing, may elect Interest Periods therefor, all as provided in this Section.
The Borrower may elect different options with respect to different portions of
the affected Borrowing, in which case each such portion shall be allocated
ratably among the Lenders holding Loans comprising such Borrowing, and the Loans
comprising each such portion shall be considered a separate Borrowing. This
Section shall not apply to Swingline Borrowings, which may not be converted or
continued.

            (b) To make an election pursuant to this Section, the Borrower shall
give the Administrative Agent prior written notice (or telephonic notice
promptly confirmed in writing) of each Borrowing substantially in the form of
Exhibit 2.10 attached hereto (a "NOTICE OF CONVERSION/CONTINUATION") that is to
be converted or continued, as the case may be, (x) prior to 11:00 a.m. (Atlanta,
Georgia time) one Business Day prior to the requested date of a conversion into
a Base Rate Borrowing and (y) prior to 11:00 a.m. (Atlanta, Georgia time) three
Business Days prior to a continuation of or conversion into a Eurodollar
Borrowing. Each such Notice of Conversion/Continuation shall be irrevocable and
shall specify (i) the Borrowing to which such Notice of Continuation/Conversion
applies and if different options are being elected with respect to different
portions thereof, the portions thereof that are to be allocated to each
resulting Borrowing (in which case the information to be specified pursuant to
clauses (iii) and (iv) shall be specified for each resulting Borrowing); (ii)
the effective date of the election made pursuant to such Notice of
Continuation/Conversion, which shall be a Business Day, (iii) whether the
resulting Borrowing is to be a Base Rate Borrowing or a Eurodollar Borrowing;
and (iv) if the resulting Borrowing is to be a Eurodollar Borrowing and the
duration of the Interest Period applicable thereto after giving effect to such
election, which shall be a period contemplated by the definition of "Interest
Period". If any such Notice of Continuation/Conversion requests a Eurodollar
Borrowing but does not specify an Interest Period, the Borrower shall be deemed
to have selected an Interest Period of one month. The principal amount of any
resulting Borrowing shall satisfy the minimum borrowing amount for Eurodollar
Borrowings and Base Rate Borrowings set forth in Section 2.3.

            (c) If, on the expiration of any Interest Period in respect of any
Eurodollar Borrowing, the Borrower shall have failed to deliver a Notice of
Conversion/Continuation, then, unless such Borrowing is repaid as provided
herein, the Borrower shall be deemed to have elected to convert such Borrowing
to a Base Rate Borrowing. No Borrowing may be converted into, or continued as, a
Eurodollar Borrowing if a Default or an Event of Default exists, unless the
Administrative Agent and each of the Lenders shall have otherwise consented in
writing. Further, any Eurodollar Borrowing that may not be continued as a
Eurodollar Borrowing as a result of a Default or Event of Default shall
automatically convert to a Base Rate Borrowing at the end of then

                                       30
<PAGE>

applicable Interest Period, and such Borrowing shall be subject to the increased
interest rate specified under Section 2.15(c) both before and after the
conversion thereof, such increased interest rate commencing on and as of the
date of such Default or Event of Default. No conversion of any Eurodollar Loans
shall be permitted except on the last day of the Interest Period in respect
thereof.

            (d) Upon receipt of any Notice of Conversion/Continuation, the
Administrative Agent shall promptly notify each Lender of the details thereof
and of such Lender's portion of each resulting Borrowing.

            SECTION 2.11. TERMINATION OF COMMITMENTS.

            Unless previously terminated, all Revolving Commitments shall
terminate on the Commitment Termination Date, except that the Swingline
Commitment shall terminate on the Swingline Termination Date.

            SECTION 2.12. REPAYMENT OF LOANS.

            (a) The outstanding principal amount of all Revolving Loans shall be
due and payable (together with accrued and unpaid interest thereon) on the
Commitment Termination Date.

            (b) The principal amount of each Swingline Loan shall be due and
payable (together with accrued interest thereon) on the earlier of (i) the last
day of the Interest Period applicable to such Loan and (ii) the Swingline
Termination Date.

            SECTION 2.13. EVIDENCE OF INDEBTEDNESS. (a) Each Lender shall
maintain in accordance with its usual practice appropriate records evidencing
the Indebtedness of the Borrower to such Lender resulting from each Loan made by
such Lender from time to time, including the amounts of principal and interest
payable thereon and paid to such Lender from time to time under this Agreement.
The Administrative Agent shall maintain appropriate records in which shall be
recorded (i) the Revolving Commitment of each Lender, (ii) the amount of each
Loan made hereunder by each Lender, the Class and Type thereof and the Interest
Period applicable thereto, (iii) the date of each continuation thereof pursuant
to Section 2.10, (iv) the date of each conversion of all or a portion thereof to
another Type pursuant to Section 2.10, (v) the date and amount of any principal
or interest due and payable or to become due and payable from the Borrower to
each Lender hereunder in respect of such Loans and (vi) both the date and amount
of any sum received by the Administrative Agent hereunder from the Borrower in
respect of the Loans and each Lender's Pro Rata Share thereof. The entries made
in such records shall be prima facie evidence of the existence and amounts of
the obligations of the Borrower therein recorded; provided, that the failure or
delay of any Lender or the Administrative Agent in maintaining or making entries
into any such record or any error therein shall not in any manner affect the
obligation of the Borrower to repay the Loans (both principal and unpaid accrued
interest) of such Lender in accordance with the terms of this Agreement.

            (b) At the request of any Lender (including the Swingline Lender) at
any time, the Borrower agrees that it will execute and deliver to such Lender a
Revolving Credit Note and, in the

                                       31
<PAGE>

case of the Swingline Lender only, a Swingline Note, payable to the order of
such Lender, and such Lender agrees, upon receipt of such new Note and request
of the Borrower, such Lender will promptly cancel and return any Note replaced
by such new Note to the Borrower.

            SECTION 2.14. OPTIONAL AND MANDATORY PREPAYMENTS.

            (a) Optional Prepayment. The Borrower shall have the right at any
time and from time to time to prepay any Borrowing, in whole or in part, without
premium or penalty, by giving irrevocable written notice (or telephonic notice
promptly confirmed in writing) to the Administrative Agent no later than (i) in
the case of prepayment of any Eurodollar Borrowing, 11:00 a.m. (Atlanta, Georgia
time) not less than three Business Days prior to any such prepayment, (ii) in
the case of any prepayment of any Base Rate Borrowing, not less than one
Business Day prior to the date of such prepayment, and (iii) in the case of
Swingline Borrowings, prior to 11:00 a.m. (Atlanta, Georgia time) on the date of
such prepayment. Each such notice shall be irrevocable and shall specify the
proposed date of such prepayment and the principal amount of each Borrowing or
portion thereof to be prepaid. Upon receipt of any such notice, the
Administrative Agent shall promptly notify each affected Lender of the contents
thereof and of such Lender's Pro Rata Share of any such prepayment. If such
notice is given, the aggregate amount specified in such notice shall be due and
payable on the date designated in such notice, together with accrued interest to
such date on the amount so prepaid in accordance with Section 2.15(d); provided,
that if a Eurodollar Borrowing is prepaid on a date other than the last day of
an Interest Period applicable thereto, the Borrower shall also pay all amounts
required pursuant to Section 2.22. Each partial prepayment of any Loan (other
than a Swingline Loan) shall be in minimum amounts of $500,000 or larger
multiples of $100,000. Each prepayment of a Borrowing shall be applied ratably
to the Loans comprising such Borrowing.

            (b)   Mandatory Prepayment.

                  (i)   Promptly upon (and in any event not later than five
      Business Days after) its receipt thereof, the Borrower shall, subject to
      clause (iv) immediately below, prepay or cause to be prepaid the
      outstanding principal amount of Revolving Loans in an amount equal to 100%
      of the Net Proceeds from any Debt Issuance made after the Closing Date,
      and will deliver to the Administrative Agent, concurrently with such
      prepayment, a certificate signed by the Chief Financial Officer of the
      Borrower in form and substance satisfactory to the Administrative Agent
      and setting forth the calculation of such Net Proceeds. Notwithstanding
      the foregoing, nothing in this subsection (i) shall be deemed to permit
      any Debt Issuance not expressly permitted under Section 7.1.

                  (ii)  Promptly upon (and in any event not later than five
      Business Days after) its receipt thereof, the Borrower shall, subject to
      clause (iv) immediately below, prepay or cause to be prepaid the
      outstanding principal amount of Revolving Loans in an amount equal to 50%
      of the Net Proceeds from any Asset Disposition (other than any Asset
      Disposition under Section 7.6(b)) and will deliver to the Administrative
      Agent, concurrently with such prepayment, a certificate signed by the
      Chief Financial Officer of the Borrower in form and substance satisfactory
      to the Administrative Agent and setting forth the calculation of such Net
      Proceeds. Notwithstanding the foregoing, nothing in this subsection (ii)
      shall be

                                       32
<PAGE>

      deemed to permit any Asset Disposition not expressly permitted under
      Section 7.6.

                  (iii) Not later than thirty days after its receipt of any
      proceeds of insurance, condemnation award or other compensation in respect
      of any Casualty Event (and in any event upon its determination not to
      repair or replace any property subject to such Casualty Event), the
      Borrower shall, subject to clause (iv) immediately below, prepay or cause
      to be prepaid the outstanding principal amount of Revolving Loans in an
      amount equal to 100% of the Net Proceeds from such Casualty Event (less
      any amounts theretofore applied, to be applied or contractually committed
      to be applied within 180 days after the occurrence of such Casualty Event
      to the repair or replacement of property subject to such Casualty Event)
      and will deliver to the Administrative Agent, concurrently with such
      prepayment, a certificate signed by the Chief Financial Officer of the
      Borrower in form and substance satisfactory to the Administrative Agent
      and setting forth the calculation of such Net Proceeds.

                  (iv)  Each prepayment of Revolving Loans made pursuant to
      clauses (i) through (iii) above shall be applied to reduce the outstanding
      principal amount of Revolving Loans, with a corresponding permanent
      reduction to the Revolving Commitment in an amount equal to the amount of
      the prepayment required by this subsection (b); provided, however, that so
      long as a prepayment of the Canadian Facility Indebtedness for the events
      described under clauses (i) through (iii) above would not have an adverse
      tax consequence for the Borrower or the Canadian Borrower (as reasonably
      determined by the Borrower), each prepayment of Revolving Loans required
      to be made pursuant to clauses (i) through (iii) above shall be applied to
      reduce the outstanding principal amount of Revolving Loans and the
      "Revolving Loans" under and as defined in the Canadian Revolving Credit
      Agreement, pro rata based on the then outstanding principal amount under
      this Agreement and the Canadian Revolving Credit Agreement, with a
      corresponding permanent reduction to the Revolving Commitment hereunder
      and a corresponding permanent reduction to the "Revolving Commitment"
      under and as defined in the Canadian Revolving Credit Agreement, in each
      case, in an amount equal to the amount so prepaid; provided, further, that
      the Canadian Prepayment Amount shall be applied solely towards the
      prepayment of the Canadian Facility Indebtedness.

                  (v)   Each prepayment of Loans made pursuant to this
      subsection (b) shall be first applied to the repayment of Base Rate Loans
      until all Base Rate Loans are paid in full, and then to Eurodollar Loans.
      Each prepayment of a Eurodollar Loan made pursuant to the provisions of
      this subsection (b) on a day other than the last day of the Interest
      Period applicable thereto shall be made together with all amounts required
      under Section 2.22.

            (c) Additional Mandatory Reduction and Permanent Repayment.
Commencing on December 31, 2005 and continuing on each June 30 and December 31
thereafter, the Aggregate Revolving Commitment shall be automatically reduced in
an amount equal to $1,250,000 until such time as the "Aggregate Revolving
Commitment" (as such term is defined in the Canadian Credit Agreement) of the
Canadian Lenders under the Canadian Revolving Credit Agreement is reduced to an
amount of not more than $22,500,000; for greater certainty this obligation shall
cease at such time, if ever, that the "Revolving Commitment" (as such term is
defined in the Canadian Credit

                                       33
<PAGE>

Agreement) under the Canadian Revolving Credit Agreement is reduced to an amount
of not more than $22,500,000 in accordance with Section 2.11(b)(i) thereof. If
at any time, as a result in the reduction of the Aggregate Revolving Commitment
under this subsection (c), the sum of the outstanding amount of the Loans plus
the LC Exposure exceeds the Aggregate Revolving Commitment, then the Borrower
shall immediately pay the amount of such excess to the Administrative Agent for
the respective accounts of the Lenders for application: first, to unreimbursed
LC Disbursements; second, to the Swingline Loans; third, to the Revolving Loans;
and fourth, to provide to the Administrative Agent cash collateral for the
aggregate undrawn amount of all outstanding Letters of Credit as contemplated by
Section 2.26(h). Each payment of any unreimbursed LC Disbursements or prepayment
of Loans shall be allocated among the Lenders, in proportion, as nearly as
practicable, to each unreimbursed LC Disbursement or (as the case may be) the
respective unpaid principal amount of any Loan owed to such Lender, with
adjustments to the extent practicable to equalize any prior payments or
repayments not exactly in proportion.

            SECTION 2.15. INTEREST ON LOANS.

            (a) The Borrower shall pay interest (i) on each Base Rate Loan at
the Base Rate in effect from time to time plus the Applicable Margin in effect
from time to time for Base Rate Loans, and (ii) on each Eurodollar Loan at the
Adjusted LIBOR for the applicable Interest Period then in effect for such
Eurodollar Loan plus the Applicable Margin in effect from time to time for
Eurodollar Loans.

            (b) The Borrower shall pay interest on each Swingline Loan at the
Swingline Rate in effect from time to time.

            (c) While an Event of Default exists or after acceleration, at the
option of the Required Lenders, the Borrower shall pay interest ("DEFAULT
INTEREST") with respect to all Eurodollar Loans at the rate otherwise applicable
for the then-current Interest Period plus an additional 2% per annum until the
last day of such Interest Period, and thereafter, and with respect to all Base
Rate Loans and all other Obligations hereunder (other than Loans), at the Base
Rate then in effect for Base Rate Loans plus the Applicable Margin for Base Rate
Loans plus an additional 2.0% per annum. While an Event of Default exists and
after acceleration, the Applicable Percentage for the letter of credit fees
provided for under Section 2.16(c) shall be increased by 2.0%.

            (d) Interest on the principal amount of all Loans shall accrue from
and including the date such Loans are made to but excluding the date of any
repayment thereof, provided such Loans are repaid within the times provided for
hereunder. Interest on all outstanding Base Rate Loans shall be payable
quarterly in arrears on the last day of each March, June, September and December
and on the Commitment Termination Date. Interest on all outstanding Eurodollar
Loans shall be payable on the last day of each Interest Period applicable
thereto, and, in the case of any Eurodollar Loans having an Interest Period in
excess of three months or 90 days, respectively, on each day which occurs every
three months or 90 days, as the case may be, after the initial date of such
Interest Period, and on the Commitment Termination Date. Interest on each
Swingline Loan shall be payable on the maturity date of such Loan, which shall
be the last day of the Interest Period applicable thereto, and on the Swingline
Termination Date. Interest on any Loan which is converted into a Loan of another
Type or which is repaid or prepaid shall be payable on the date of such

                                       34
<PAGE>

conversion or on the date of any such repayment or prepayment (on the amount
repaid or prepaid) thereof. All Default Interest and increased letter of credit
fees payable under subsection (c) of this Section shall be payable on demand.

            (e) The Administrative Agent shall determine each interest rate
applicable to the Loans hereunder and shall promptly notify the Borrower and the
Lenders of such rate in writing (or by telephone, promptly confirmed in
writing). Any such determination shall be conclusive and binding for all
purposes, absent manifest error.

            SECTION 2.16. FEES.

            (a) Administrative Agent's Fees. The Borrower shall pay to the
Administrative Agent for its own account fees in the amounts and at the times
previously agreed upon by the Borrower and the Administrative Agent.

            (b) Commitment Fee. The Borrower agrees to pay to the Administrative
Agent for the account of each Lender a commitment fee, which fee shall accrue at
the Applicable Percentage on the average daily amount of the unused Revolving
Commitment of such Lender during the Availability Period. Accrued commitment
fees shall be payable in arrears on the last day of each March, June, September
and December of each year and on the Commitment Termination Date, commencing on
the first such date after the Closing Date. For purposes of computing commitment
fees with respect to the Revolving Commitments, the Revolving Commitment of each
Lender shall be deemed used to the extent of the outstanding Revolving Loans and
LC Exposure of such Lender. Any Swingline Loans outstanding shall be treated as
if such Loan were unused for purposes of this subsection (b).

            (c) Letter of Credit Fees. The Borrower agrees to pay (i) to the
Administrative Agent, for the account of each Lender, a letter of credit fee
with respect to its participation in each Letter of Credit (including the
Existing Letters of Credit), which shall accrue at the Applicable Percentage
then in effect on the average daily amount of such Lender's LC Exposure
(excluding any portion thereof attributable to unreimbursed LC Disbursements)
attributable to such Letter of Credit during the period from and including the
date of issuance of such Letter of Credit to but excluding the date on which
such Letter of Credit expires or is drawn in full (including without limitation
any LC Exposure that remains outstanding after the Commitment Termination Date)
and (ii) to the Issuing Bank for its own account a fronting fee, which shall
accrue at the rate of 0.125% per annum on the average daily amount of the LC
Exposure (excluding any portion thereof attributable to unreimbursed LC
Disbursements) during the Availability Period (or until the date that such
Letter of Credit is irrevocably cancelled, whichever is later), as well as the
Issuing Bank's standard fees with respect to issuance, amendment, renewal or
extension of any Letter of Credit or processing of drawings thereunder.
Notwithstanding any term of any letter of credit application, reimbursement
agreement or other agreement entered into between the Borrower and the Issuing
Bank in connection with any Existing Letter of Credit which term relates to fees
payable in connection with such Existing Letter of Credit, the terms of this
Section regarding letter of credit fees and fronting fees shall control from and
after the Closing Date.

                                       35
<PAGE>

            (d) Payments. Accrued fees (other than the Administrative Agent's
fees in subsection (a) above) shall be payable quarterly in arrears on the last
day of each of March, June, September and December, commencing on the first such
date after the Closing Date and on the Commitment Termination Date (and if
later, the date the Loans and LC Exposure shall be repaid in their entirety).

            SECTION 2.17. EFFECTIVE DATE FOR ADJUSTMENT TO APPLICABLE PERCENTAGE
AND APPLICABLE MARGIN. The Applicable Percentage and Applicable Margin shall be
determined and adjusted quarterly on the date that is two Business Days after
the date on which the Borrower provides the officer's certificate in accordance
with the provisions of Section 5.1.(c) (each "Margin Calculation Date");
provided, however that (i) the Applicable Percentage and the Applicable Margin
from the Closing Date until the first Margin Calculation Date subsequent to the
Closing Date shall be at Level V (as set forth in Schedule I), and, thereafter,
such level shall be determined by the then current Leverage Ratio, and (ii) if
the Borrower fails to provide the officer's certificate to the Administrative
Agent by the date such certificate is required to be delivered under Section
5.1.(c), the Applicable Percentage and the Applicable Margin from such date
shall be at Level V until such time as an appropriate officer's certificate is
provided, whereupon the level shall be determined by the then current Leverage
Ratio. Except as set forth above, the Applicable Percentage and the Applicable
Margin shall be effective from one Margin Calculation Date until the next Margin
Calculation Date.

            SECTION 2.18. COMPUTATION OF INTEREST AND FEES. All computations of
interest and all fees hereunder shall be made on the basis of a year of 360 days
and paid for the actual number of days elapsed (including the first day but
excluding the last day). Each determination by the Administrative Agent of an
interest amount or fee hereunder shall be made in good faith and, except for
manifest error, shall be final, conclusive and binding for all purposes.

            SECTION 2.19. INABILITY TO DETERMINE INTEREST RATES. If prior to the
commencement of any Interest Period for any Eurodollar Borrowing,

            (i)   the Administrative Agent shall have determined (which
      determination shall be conclusive and binding upon the Borrower) that, by
      reason of circumstances affecting the relevant interbank market, adequate
      means do not exist for ascertaining the LIBOR for such Interest Period, or

            (ii)  the Administrative Agent shall have received notice from the
      Required Lenders that the Adjusted LIBOR does not adequately and fairly
      reflect the cost to such Lenders of making, funding or maintaining their
      Eurodollar Loans for such Interest Period,

the Administrative Agent shall give written notice (or telephonic notice,
promptly confirmed in writing) to the Borrower and to the Lenders as soon as
practicable thereafter. In the case of Eurodollar Loans, until the
Administrative Agent shall notify the Borrower and the Lenders that the
circumstances giving rise to such notice no longer exist, (A) the obligations of
the Lenders to make Eurodollar Revolving Loans or to continue or convert
outstanding Loans as or into Eurodollar Loans shall be suspended and (B) all
such affected Loans shall be converted into Base Rate Loans on the

                                       36
<PAGE>

last day of the then current Interest Period applicable thereto unless the
Borrower repays or prepays such Loans in accordance with this Agreement. Unless
the Borrower notifies the Administrative Agent at least one Business Day before
the date of any Eurodollar Borrowing for which a Notice of Revolving Borrowing
has previously been given that it elects not to borrow on such date, then such
Borrowing shall be made as a Base Rate Borrowing.

            SECTION 2.20. ILLEGALITY. If any Change in Law shall make it
unlawful or impossible for any Lender to make, maintain or fund any Eurodollar
Loan and such Lender shall so notify the Administrative Agent, the
Administrative Agent shall promptly give notice thereof to the Borrower and the
other Lenders, whereupon until such Lender notifies the Administrative Agent and
the Borrower that the circumstances giving rise to such suspension no longer
exist, the obligation of such Lender to make Eurodollar Revolving Loans or to
continue or convert outstanding Loans as or into Eurodollar Loans shall be
suspended. In the case of the making of a Eurodollar Borrowing, such Lender's
Revolving Loan shall be made as a Base Rate Loan as part of the same Borrowing
for the same Interest Period and if the affected Eurodollar Loan is then
outstanding, such Loan shall be converted to a Base Rate Loan either (i) on the
last day of the then current Interest Period applicable to such Eurodollar Loan
if such Lender may lawfully continue to maintain such Loan to such date or (ii)
immediately if such Lender shall determine that it may not lawfully continue to
maintain such Eurodollar Loan to such date. Notwithstanding the foregoing, the
affected Lender shall, prior to giving such notice to the Administrative Agent,
designate a different Applicable Lending Office if such designation would avoid
the need for giving such notice and if such designation would not otherwise be
disadvantageous to such Lender in the good faith exercise of its discretion.

            SECTION 2.21. INCREASED COSTS.

            (a)   If any Change in Law shall:

                  (i)   impose, modify or deem applicable any reserve, special
      deposit or similar requirement that is not otherwise included in the
      determination of the Adjusted LIBOR hereunder against assets of, deposits
      with or for the account of, or credit extended by, any Lender (except any
      such reserve requirement reflected in the Adjusted LIBOR ) or the Issuing
      Bank; or

                  (ii)  impose on any Lender or on the Issuing Bank or the
      Eurodollar interbank market any other condition affecting this Agreement
      or any Eurodollar Loans made by such Lender or any Letter of Credit or any
      participation therein;

and the result of the foregoing is to increase the cost to such Lender of
making, converting into, continuing or maintaining a Eurodollar Loan, or to
increase the cost to such Lender or the Issuing Bank of participating in or
issuing any Letter of Credit or to reduce the amount received or receivable by
such Lender or the Issuing Bank hereunder (whether of principal, interest or any
other amount), then the Borrower shall promptly pay, upon written notice from
and demand by such Lender on the Borrower (with a copy of such notice and demand
to the Administrative Agent), to the Administrative Agent for the account of
such Lender, within five Business Days after the date of

                                       37
<PAGE>

such notice and demand, additional amount or amounts sufficient to compensate
such Lender or the Issuing Bank, as the case may be, for such additional costs
incurred or reduction suffered.

            (b) If any Lender or the Issuing Bank shall have determined that on
or after the date of this Agreement any Change in Law regarding capital
requirements has or would have the effect of reducing the rate of return on such
Lender's or the Issuing Bank's capital (or on the capital of such Lender's or
the Issuing Bank's parent corporation) as a consequence of its obligations
hereunder or under or in respect of any Letter of Credit to a level below that
which such Lender or the Issuing Bank or such Lender's or the Issuing Bank's
parent corporation could have achieved but for such Change in Law (taking into
consideration such Lender's or the Issuing Bank's policies or the policies of
such Lender's or the Issuing Bank's parent corporation with respect to capital
adequacy) then, from time to time, within five Business Days after receipt by
the Borrower of written demand by such Lender (with a copy thereof to the
Administrative Agent), the Borrower shall pay to such Lender such additional
amounts as will compensate such Lender or the Issuing Bank or such Lender's or
the Issuing Bank's parent corporation for any such reduction suffered.

            (c) [RESERVED]

            (d) [RESERVED]

            (e) A certificate of a Lender or the Issuing Bank setting forth the
amount or amounts necessary to compensate such Lender or the Issuing Bank or
such Lender's or the Issuing Bank's holding company, as the case may be,
specified in paragraph (a) or (b) of this Section shall be delivered to the
Borrower (with a copy to the Administrative Agent) and shall be conclusive,
absent manifest error. The Borrower shall pay any such Lender or the Issuing
Bank, as the case may be, such amount or amounts within 10 days after receipt
thereof.

            (f) Failure or delay on the part of any Lender or the Issuing Bank
to demand compensation pursuant to this Section shall not constitute a waiver of
such Lender's or the Issuing Bank's right to demand such compensation; provided,
that the Borrower shall not be required to compensate a Lender or the Issuing
Bank under this Section for any increased costs or reductions incurred more than
six months prior to the date that such Lender or the Issuing Bank notifies the
Borrower of such increased costs or reductions and of such Lender's or the
Issuing Bank's intention to claim compensation therefore; provided further, that
if the Change in Law giving rise to such increased costs or reductions is
retroactive, then such six-month period shall be extended to include the period
of such retroactive effect.

            SECTION 2.22. FUNDING INDEMNITY. In the event of (a) the payment of
any principal of a Eurodollar Loan other than on the last day of the Interest
Period applicable thereto (including as a result of an Event of Default), (b)
the conversion or continuation of a Eurodollar Loan other than on the last day
of the Interest Period applicable thereto or (c) the failure by the Borrower to
borrow, prepay, convert or continue any Eurodollar Loan on the date specified in
any applicable notice (regardless of whether such notice is withdrawn or
revoked), then, in any such event, the Borrower shall compensate each Lender,
within five Business Days after written demand from such Lender, for any loss,
cost or expense attributable to such event. In the case of a Eurodollar Loan,
such loss, cost

                                       38
<PAGE>

or expense shall be deemed to include an amount determined by such Lender to be
the excess, if any, of (i) the amount of interest that would have accrued on the
principal amount of such Eurodollar Loan if such event had not occurred at the
Adjusted LIBOR applicable to such Eurodollar Loan for the period from the date
of such event to the last day of the then current Interest Period therefor (or
in the case of a failure to borrow, convert or continue, for the period that
would have been the Interest Period for such Eurodollar Loan) over (ii) the
amount of interest that would accrue on the principal amount of such Eurodollar
Loan for the same period if the Adjusted LIBOR were set on the date such
Eurodollar Loan was prepaid or converted or the date on which the Borrower
failed to borrow, convert or continue such Eurodollar Loan. A certificate as to
any additional amount payable under this Section 2.22 submitted to the Borrower
by any Lender shall be conclusive, absent manifest error.

            SECTION 2.23. TAXES.

            (a) Any and all payments by or on account of any obligation of the
Borrower hereunder shall be made free and clear of and without deduction for any
Indemnified Taxes or Other Taxes; provided, that if the Borrower shall be
required to deduct any Indemnified Taxes or Other Taxes from such payments, then
(i) the sum payable shall be increased as necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section) the Administrative Agent, any Lender or the Issuing Bank (as
the case may be) shall receive an amount equal to the sum it would have received
had no such deductions been made, (ii) the Borrower shall make such deductions
and (iii) the Borrower shall pay the full amount deducted to the relevant
Governmental Authority in accordance with applicable law.

            (b) In addition, the Borrower shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

            (c) The Borrower shall indemnify the Administrative Agent, each
Lender and the Issuing Bank, within five Business Days after written demand
therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by
the Administrative Agent, such Lender or the Issuing Bank, as the case may be,
on or with respect to any payment by or on account of any obligation of the
Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or
asserted on or attributable to amounts payable under this Section) and any
penalties, interest and reasonable expenses arising therefrom or with respect
thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or
legally imposed or asserted by the relevant Governmental Authority. A
certificate as to the amount of such payment or liability delivered to the
Borrower by a Lender or the Issuing Bank, or by the Administrative Agent on its
own behalf or on behalf of a Lender or the Issuing Bank, shall be conclusive
absent manifest error.

            (d) As soon as practicable after any payment of Indemnified Taxes or
Other Taxes by the Borrower to a Governmental Authority, the Borrower shall
deliver to the Administrative Agent the original or a certified copy of a
receipt issued by such Governmental Authority evidencing such payment, a copy of
the return reporting such payment or other evidence of such payment reasonably
satisfactory to the Administrative Agent.

                                       39
<PAGE>

            (e) Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax under the Code, or any treaty to which the United
States is a party, with respect to payments under this Agreement shall deliver
to the Borrower (with a copy to the Administrative Agent), at the time or times
prescribed by applicable law, such properly completed and executed documentation
prescribed by applicable law or reasonably requested by the Borrower as will
permit such payments to be made without withholding or at a reduced rate.
Without limiting the generality of the foregoing, each Foreign Lender agrees
that it will deliver to the Administrative Agent and the Borrower (or in the
case of a Participant, to the Lender from which the related participation shall
have been purchased) two duly completed copies of (i) Internal Revenue Service
Form W-8 ECI, or any successor form thereto, certifying that the payments
received from the Borrower hereunder are effectively connected with such Foreign
Lender's conduct of a trade or business in the United States or (ii) Internal
Revenue Service Form W-8 BEN, or any successor form thereto, certifying that
such Foreign Lender is entitled to benefits under an income tax treaty to which
the Untied States is a party which reduces the rate of withholding tax on
payments of interest or (iii) Internal Revenue Service Form W-8 BEN, or any
successor form prescribed by the Internal Revenue Service; or (iv) such other
Internal Revenue Service forms as may be applicable to the Foreign Lender,
including Forms W-8 IMY or W-8 EXP. Each such Foreign Lender shall deliver to
the Borrower and the Administrative Agent such forms on or before the date that
it becomes a party to this Agreement (or in the case of a Participant, on or
before the date such Participant purchases the related participation). In
addition, each such Lender shall deliver such forms promptly upon the
obsolescence or invalidity of any form previously delivered by such Lender. Each
such Lender shall promptly notify the Borrower and the Administrative Agent at
any time that it determines that it is no longer in a position to provide any
previously delivered certificate to the Borrower (or any other form of
certification adopted by the Internal Revenue Service for such purpose).

            (f) If the Borrower pays any additional amounts under this Section
2.23 to a Lender and such Lender reasonably determines that it has actually
received or realized in connection therewith any refund or any reduction of, or
credit against, its Tax liabilities in or with respect to the taxable year in
which the additional amount is paid (a "Tax Benefit"), such Lender shall pay to
the Borrower an amount that such Lender shall reasonably determine is equal to
the net benefit, after tax, which was obtained by such Lender in such year as a
consequence of such Tax Benefit; provided, however, that (i) any Lender may
reasonably determine whether to seek a Tax Benefit, (ii) any Taxes that are
imposed on a Lender as a result of a disallowance or reduction (including
through the expiration of any tax credit carryover or carryback of such Lender
that otherwise would not have expired) of any Tax Benefit with respect to which
such Lender has made a payment to the Borrower pursuant to this Section shall be
treated as a Tax for which the Borrower is obligated to indemnify such Lender
pursuant to this Section without any exclusions or defenses and (iii) nothing in
this Section shall require any Lender to disclose any confidential information
to the Borrower (including, without limitation, its tax returns). If the
Borrower determines in good faith that a reasonable basis exists for contesting
any Taxes for which indemnification has been demanded hereunder, the relevant
Lender or the Administrative Agent, as applicable, shall cooperate with the
Borrower in challenging such Taxes at the Borrower's sole cost and expense if so
requested by the Borrower in writing.

            SECTION 2.24. PAYMENTS GENERALLY; PRO RATA TREATMENT; SHARING
OFSET-OFFS.

                                       40
<PAGE>

            (a) The Borrower shall make each payment required to be made
hereunder (whether of principal, interest, fees or reimbursement of LC
Disbursements, or of amounts payable under Section 2.21, 2.22 or 2.23, or
otherwise) prior to 12:00 noon (Atlanta, Georgia time) on the date when due, in
immediately available funds, free and clear of any claims or defenses, and
without deduction, withholding, set-off or counterclaim of any kind. Any amounts
received after such time on any date may, in the discretion of the
Administrative Agent, be deemed to have been received on the next succeeding
Business Day for purposes of calculating interest thereon. All such payments
shall be made to the Administrative Agent at the Payment Office, except payments
to be made directly to the Issuing Bank or Swingline Lender as expressly
provided herein and except that payments pursuant to Sections 2.21, 2.22 and
2.23 and 10.3 shall be made directly to the Persons entitled thereto. The
Administrative Agent shall distribute any such payments received by it for the
account of any other Person to the appropriate recipient promptly following
receipt thereof. If any payment hereunder shall be due on a day that is not a
Business Day, the date for payment shall be extended to the next succeeding
Business Day, and, in the case of any payment accruing interest, interest
thereon shall be made payable for the period of such extension. All payments
hereunder shall be made in Dollars.

            (b) If at any time insufficient funds are received by and available
to the Administrative Agent to pay fully all amounts of principal, unreimbursed
LC Disbursements, interest and fees then due hereunder, such funds shall be
applied (i) first, towards payment of interest and fees then due hereunder,
ratably among the parties entitled thereto in accordance with the amounts of
interest and fees then due to such parties, and (ii) second, towards payment of
principal and unreimbursed LC Disbursements then due hereunder, ratably among
the parties entitled thereto in accordance with the amounts of principal and
unreimbursed LC Disbursements then due to such parties.

            (c) If any Lender shall, by exercising any right of set-off or
counterclaim or otherwise, obtain payment in respect of any principal of or
interest on any of its Revolving Loans or participations in LC Disbursements or
Swingline Loans that would result in such Lender receiving payment of a greater
proportion of the aggregate amount of its Revolving Loans and participations in
LC Disbursements and Swingline Loans and accrued interest thereon than the
proportion received by any other Lender, then the Lender receiving such greater
proportion shall purchase (for cash at face value) participations in the
Revolving Loans and participations in LC Disbursements and Swingline Loans of
other Lenders to the extent necessary so that the benefit of all such payments
shall be shared by the Lenders ratably in accordance with the aggregate amount
of principal of and accrued interest on their respective Revolving Loans and
participations in LC Disbursements and Swingline Loans; provided, that (i) if
any such participations are purchased and all or any portion of the payment
giving rise thereto is recovered, such participations shall be rescinded and the
purchase price restored to the extent of such recovery, without interest, and
(ii) the provisions of this paragraph shall not be construed to apply to any
payment made by the Borrower pursuant to and in accordance with the express
terms of this Agreement or any payment obtained by a Lender as consideration for
the assignment of or sale of a participation in any of its Loans or
participations in LC Disbursements or Swingline Loans to any assignee or
participant, other than to the Borrower or any Subsidiary or Affiliate thereof
(as to which the provisions of this paragraph shall apply). The Borrower
consents to the foregoing and agrees, to the extent it may effectively do so
under applicable

                                       41
<PAGE>

law, that any Lender acquiring a participation pursuant to the foregoing
arrangements may exercise against the Borrower rights of set-off and
counterclaim with respect to such participation as fully as if such Lender were
a direct creditor of the Borrower in the amount of such participation.

            (d) Unless the Administrative Agent shall have received notice from
the Borrower prior to the date on which any payment is due to the Administrative
Agent for the account of the Lenders or the Issuing Bank hereunder that the
Borrower will not make such payment, the Administrative Agent may assume that
the Borrower has made such payment on such date in accordance herewith and may,
in reliance upon such assumption, distribute to the Lenders or the Issuing Bank,
as the case may be, the amount or amounts due. In such event, if the Borrower
has not in fact made such payment, then each of the Lenders or the Issuing Bank,
as the case may be, severally agrees to repay to the Administrative Agent
forthwith on demand the amount so distributed to such Lender or Issuing Bank
with interest thereon, for each day from and including the date such amount is
distributed to it to but excluding the date of payment to the Administrative
Agent, at the greater of the Federal Funds Effective Rate and a rate determined
by the Administrative Agent in accordance with banking industry rules on
interbank compensation.

            (e) If any Lender shall fail to make any payment required to be made
by it pursuant to Section 2.5(b), 2.9, 2.24(d) 2.26(e), or 10.3(d), then the
Administrative Agent may, in its discretion (notwithstanding any contrary
provision hereof), apply any amounts thereafter received by the Administrative
Agent for the account of such Lender to satisfy such Lender's obligations under
such Sections until all such unsatisfied obligations are fully paid.

            SECTION 2.25. MITIGATION OF OBLIGATIONS; REPLACEMENT OF LENDERS.

            (a) If any Lender requests compensation under Section 2.21, or if
the Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.23,
then such Lender shall use reasonable efforts to designate a different lending
office for funding or booking its Loans hereunder or to assign its rights and
obligations hereunder to another of its offices, branches or affiliates, if, in
the sole judgment of such Lender, such designation or assignment (i) would
eliminate or reduce amounts payable under Section 2.21 or Section 2.23, as the
case may be, in the future and (ii) would not subject such Lender to any
unreimbursed cost or expense and would not otherwise be disadvantageous to such
Lender. The Borrower hereby agrees to pay all reasonable costs and expenses
incurred by any Lender in connection with such designation or assignment made
with the knowledge or at the request of the Borrower.

            (b) If any Lender requests compensation under Section 2.21, or if
the Borrower is required to pay any additional amount to any Lender or any
Governmental Authority of the account of any Lender pursuant to Section 2.23, or
any Lender is unable to make Eurodollar Loans for the reasons set forth in
Section 2.20 or if any Lender defaults in its obligation to fund Loans
hereunder, then the Borrower may, at its sole expense and effort, upon notice to
such Lender and the Administrative Agent, require such Lender to assign and
delegate, without recourse (in accordance with and subject to the restrictions
set forth in Section 10.4(b)) all its interests, rights and obligations under
this Agreement to an assignee that shall assume such obligations (which assignee
may be

                                       42
<PAGE>

another Lender); provided, that (i) the Borrower shall have received the prior
written consent of the Administrative Agent, which consent shall not be
unreasonably withheld, (ii) such Lender shall have received payment of an amount
equal to the outstanding principal amount of all Loans owed to it, accrued
interest thereon, accrued fees and all other amounts payable to it hereunder,
from the assignee (in the case of such outstanding principal and accrued
interest) and from the Borrower (in the case of all other amounts) and (iii) in
the case of a claim for compensation under Section 2.21 or payments required to
be made pursuant to Section 2.23, such assignment will result in a reduction in
such compensation or payments. A Lender shall not be required to make any such
assignment and delegation if, prior thereto, as a result of a waiver by such
Lender or otherwise, the circumstances entitling the Borrower to require such
assignment and delegation cease to apply.

            SECTION 2.26. LETTERS OF CREDIT.

            (a) During the Availability Period, the Issuing Bank, in reliance
upon the agreements of the other Lenders pursuant to Section 2.26(e), agrees to
issue, at the request of the Borrower, Letters of Credit for the account of the
Borrower on the terms and conditions hereinafter set forth; provided, that (i)
each Letter of Credit shall be a standby letter of credit which shall expire on
the earlier of (A) the date one year after the date of issuance of such Letter
of Credit (or in the case of any renewal or extension thereof, one year after
such renewal or extension) and (B) the date that is five Business Days prior to
the Commitment Termination Date; (ii) each Letter of Credit shall be in a stated
amount of at least $50,000; and (iii) the Borrower may not request any Letter of
Credit, if, after giving effect to such issuance (A) the aggregate LC Exposure
would exceed the LC Commitment or (B) the aggregate LC Exposure, plus the
aggregate outstanding Revolving Loans of all Lenders would exceed the Aggregate
Revolving Commitments. Upon the issuance of each Letter of Credit (including the
Existing Letters of Credit), each Lender shall be deemed to, and hereby
irrevocably and unconditionally agrees to, purchase from the Issuing Bank
without recourse a participation in such Letter of Credit equal to such Lender's
Pro Rata Share of the aggregate amount available to be drawn under such Letter
of Credit. Each issuance of a Letter of Credit shall be deemed to utilize the
Revolving Commitment of each Lender by an amount equal to the amount of such
participation.

            (b) Each of the parties hereto: (i) acknowledges that, prior to the
Closing Date, the Issuing Bank issued the Existing Letters of Credit for the
account of the Borrower and (ii) agrees that the Existing Letters of Credit
shall, for all purposes be deemed to constitute a Letter of Credit issued by the
Issuing Bank pursuant to this Agreement for the account of the Borrower. The
Existing Letters of Credit shall be deemed to be issued on and as of the Closing
Date and the L/C Commitment shall be deemed to have automatically been reduced
on the Closing Date in an amount equal to the aggregate stated amount of the
Existing Letters of Credit. The Issuing Bank shall, upon the request of any
Lender, deliver copies of any information concerning the Existing Letters of
Credit as any such Lender may reasonably request. All of the parties hereto
agree that in the event there is any inconsistency between the terms of the
letter of credit agreement or application or reimbursement agreement with
respect to an Existing Letter of Credit and this Agreement including, without
limitation, terms relating to the timing of reimbursement, fees, standards of
conduct and other matters, the terms of this Agreement shall control.

                                       43
<PAGE>

            (c) To request the issuance of a Letter of Credit (or any amendment,
renewal or extension of an outstanding Letter of Credit) (other than the
Existing Letters of Credit), the Borrower shall give the Issuing Bank and the
Administrative Agent irrevocable written notice at least three Business Days
prior to the requested date of such issuance specifying the date (which shall be
a Business Day) such Letter of Credit is to be issued (or amended, extended or
renewed, as the case may be), the expiration date of such Letter of Credit, the
amount of such Letter of Credit, the name and address of the beneficiary thereof
and such other information as shall be necessary to prepare, amend, renew or
extend such Letter of Credit. In addition to the satisfaction of the conditions
in Article III, the issuance of such Letter of Credit (or any amendment which
increases the amount of such Letter of Credit) will be subject to the further
conditions that such Letter of Credit shall be in such form and contain such
terms as the Issuing Bank shall approve and that the Borrower shall have
executed and delivered any additional applications, agreements and instruments
relating to such Letter of Credit as the Issuing Bank shall reasonably require;
provided, that in the event of any conflict between such applications,
agreements or instruments and this Agreement, the terms of this Agreement shall
control.

            (d) At least two Business Days prior to the issuance of any Letter
of Credit, the Issuing Bank will confirm with the Administrative Agent (by
telephone or in writing) that the Administrative Agent has received such notice
and if not, the Issuing Bank will provide the Administrative Agent with a copy
thereof. Unless the Issuing Bank has received notice from the Administrative
Agent on or before the Business Day immediately preceding the date the Issuing
Bank is to issue the requested Letter of Credit directing the Issuing Bank not
to issue the Letter of Credit because such issuance is not then permitted
hereunder because of the limitations set forth in Section 2.26(a) or that one or
more conditions specified in Article III are not then satisfied, then, subject
to the terms and conditions hereof, the Issuing Bank shall, on the requested
date, issue such Letter of Credit in accordance with the Issuing Bank's usual
and customary business practices.

            (e) The Issuing Bank shall examine all documents purporting to
represent a demand for payment under a Letter of Credit promptly following its
receipt thereof. The Issuing Bank shall notify the Borrower and the
Administrative Agent of such demand for payment and whether the Issuing Bank has
made or will make a LC Disbursement thereunder; provided, that any failure to
give or delay in giving such notice shall not relieve the Borrower of its
obligation to reimburse the Issuing Bank and the Lenders with respect to such LC
Disbursement. The Borrower shall be irrevocably and unconditionally obligated to
reimburse the Issuing Bank for any LC Disbursements paid by the Issuing Bank in
respect of such drawing, without presentment, demand or other formalities of any
kind. Unless the Borrower shall have notified the Issuing Bank and the
Administrative Agent prior to 11:00 a.m. (Atlanta, Georgia time) on the Business
Day immediately prior to the date on which such drawing is honored that the
Borrower intends to reimburse the Issuing Bank for the amount of such drawing in
funds other than from the proceeds of Revolving Loans, the Borrower shall be
deemed to have timely given a Notice of Revolving Borrowing to the
Administrative Agent requesting the Lenders to make a Base Rate Borrowing on the
date on which such drawing is honored in an exact amount due to the Issuing
Bank; provided, that for purposes solely of such Borrowing, the conditions
precedent set forth in Section 3.2 hereof shall not be applicable. The
Administrative Agent shall notify the Lenders of such Borrowing in accordance
with Section 2.3, and each Lender shall make the proceeds of its Base Rate Loan
included in such

                                       44
<PAGE>

Borrowing available to the Administrative Agent for the account of the Issuing
Bank in accordance with Section 2.9. The proceeds of such Borrowing shall be
applied directly by the Administrative Agent to reimburse the Issuing Bank for
such LC Disbursement.

            (f) If for any reason a Base Rate Borrowing may not be (as
determined in the sole discretion of the Administrative Agent), or is not, made
in accordance with the foregoing provisions, then each Lender (other than the
Issuing Bank) shall be obligated to fund the participation that such Lender
purchased pursuant to subsection (a) in an amount equal to its Pro Rata Share of
such LC Disbursement on and as of the date which such Base Rate Borrowing should
have occurred. Each Lender's obligation to fund its participation shall be
absolute and unconditional and shall not be affected by any circumstance,
including without limitation (i) any setoff, counterclaim, recoupment, defense
or other right that such Lender or any other Person may have against the Issuing
Bank or any other Person for any reason whatsoever, (ii) the existence of a
Default or an Event of Default or the termination of the Aggregate Revolving
Commitments, (iii) any adverse change in the condition (financial or otherwise)
of the Borrower or any Subsidiary, (iv) any breach of this Agreement by the
Borrower or any other Lender, (v) any amendment, renewal or extension of any
Letter of Credit or (vi) any other circumstance, happening or event whatsoever,
whether or not similar to any of the foregoing. On the date that such
participation is required to be funded, each Lender shall promptly transfer, in
immediately available funds, the amount of its participation to the
Administrative Agent for the account of the Issuing Bank. Whenever, at any time
after the Issuing Bank has received from any such Lender the funds for its
participation in a LC Disbursement, the Issuing Bank (or the Administrative
Agent on its behalf) receives any payment on account thereof, the Administrative
Agent or the Issuing Bank, as the case may be, will distribute to such Lender
its Pro Rata Share of such payment; provided, that if such payment is required
to be returned for any reason to the Borrower or to a trustee, receiver,
liquidator, custodian or similar official in any bankruptcy proceeding, such
Lender will return to the Administrative Agent or the Issuing Bank any portion
thereof previously distributed by the Administrative Agent or the Issuing Bank
to it.

            (g) To the extent that any Lender shall fail to pay any amount
required to be paid pursuant to paragraph (e) of this Section 2.26 on the due
date therefor, such Lender shall pay interest to the Issuing Bank (through the
Administrative Agent) on such amount from such due date to the date such payment
is made at a rate per annum equal to the Federal Funds Rate; provided, that if
such Lender shall fail to make such payment to the Issuing Bank within three
Business Days of such due date, then, retroactively to the due date, such Lender
shall be obligated to pay interest on such amount at the Default Rate.

            (h) If any Event of Default shall occur and be continuing, on the
Business Day that the Borrower receives notice from the Administrative Agent or
the Required Lenders demanding the deposit of cash collateral pursuant to this
paragraph, the Borrower shall deposit in an account with the Administrative
Agent, in the name of the Administrative Agent and for the benefit of the
Lenders, an amount in cash equal to the LC Exposure as of such date plus any
accrued and unpaid interest thereon; provided, that the obligation to deposit
such cash collateral shall become effective immediately, and such deposit shall
become immediately due and payable, with demand or notice of any kind, upon the
occurrence of any Event of Default with respect to the Borrower described in
subsection (g) or (h) of Section 8.1. Such deposit shall be held by the
Administrative Agent as

                                       45
<PAGE>

collateral in an interest bearing account (which account shall be chosen in the
sole discretion of the Administrative Agent and at the Borrower's risk and
expense) for the payment and performance of the obligations of the Borrower
under this Agreement. The Administrative Agent shall have exclusive dominion and
control, including the exclusive right of withdrawal, over such account.
Interest and profits on such investments shall accumulate in such account.
Moneys in such account shall be applied by the Administrative Agent to reimburse
the Issuing Bank for LC Disbursements for which it had not been reimbursed and
to the extent not so applied, shall be held for the satisfaction of the
reimbursement obligations of the Borrower for the LC Exposure at such time or,
if the maturity of the Loans has been accelerated, with the consent of the
Required Lenders, be applied to satisfy other obligations of the Borrower under
this Agreement. If the Borrower is required to provide an amount of cash
collateral hereunder as a result of the occurrence of an Event of Default, such
amount (to the extent not so applied as aforesaid) shall be returned to the
Borrower within three Business Days after all Events of Default have been cured
or waived.

            (i) Promptly following the end of each fiscal quarter, the Issuing
Bank shall deliver (through the Administrative Agent) to each Lender and the
Borrower a report describing the aggregate Letters of Credit outstanding at the
end of such fiscal quarter. Upon the request of any Lender from time to time,
the Issuing Bank shall deliver to such Lender any other information reasonably
requested by such Lender with respect to each Letter of Credit then outstanding.

            (j) The Borrower's obligation to reimburse LC Disbursements
hereunder shall be absolute, unconditional and irrevocable and shall be
performed strictly in accordance with the terms of this Agreement under all
circumstances whatsoever and irrespective of any of the following circumstances:

                  (i)   Any lack of validity or enforceability of any Letter of
      Credit or this Agreement;

                  (ii)  The existence of any claim, set-off, defense or other
      right which the Borrower or any Subsidiary or Affiliate of the Borrower
      may have at any time against a beneficiary or any transferee of any Letter
      of Credit (or any Persons or entities for whom any such beneficiary or
      transferee may be acting), any Lender (including the Issuing Bank) or any
      other Person, whether in connection with this Agreement or the Letter of
      Credit or any document related hereto or thereto or any unrelated
      transaction;

                  (iii) Any draft or other document presented under a Letter of
      Credit proving to be forged, fraudulent or invalid in any respect or any
      statement therein being untrue or inaccurate in any respect;

                  (iv)  Payment by the Issuing Bank under a Letter of Credit
      against presentation of a draft or other document to the Issuing Bank that
      does not comply with the terms of such Letter of Credit;

                  (v)   Any other event or circumstance whatsoever, whether or
      not similar to any of the foregoing, that might, but for the provisions of
      this Section, constitute a legal or

                                       46
<PAGE>

      equitable discharge of, or provide a right of setoff against, the
      Borrower's obligations hereunder; or

                  (vi)  The existence of a Default or an Event of Default.

Neither the Administrative Agent, the Issuing Bank, the Lenders nor any Related
Party of any of the foregoing shall have any liability or responsibility by
reason of or in connection with the issuance or transfer of any Letter of Credit
or any payment or failure to make any payment thereunder (irrespective of any of
the circumstances referred to above), or any error, omission, interruption, loss
or delay in transmission or delivery of any draft, notice or other communication
under or relating to any Letter of Credit (including any document required to
make a drawing thereunder), any error in interpretation of technical terms or
any consequence arising from causes beyond the control of the Issuing Bank;
provided, that nothing in this Agreement, any Letter of Credit or any other Loan
Document shall be construed to excuse the Issuing Bank from liability to the
Borrower to the extent of any direct damages (as opposed to consequential
damages, claims in respect of which are hereby waived by the Borrower to the
extent permitted by applicable law) suffered by the Borrower that are caused by
the Issuing Bank's failure to exercise care when determining whether drafts or
other documents presented under a Letter of Credit comply with the terms
thereof. The parties hereto expressly agree, that in the absence of gross
negligence or willful misconduct on the part of the Issuing Bank (as finally
determined by a court of competent jurisdiction), the Issuing Bank shall be
deemed to have exercised care in each such determination. In furtherance of the
foregoing and without limiting the generality thereof, the parties agree that,
with respect to documents presented that appear on their face to be in
substantial compliance with the terms of a Letter of Credit, the Issuing Bank
may, in its sole discretion, either accept and make payment upon such documents
without responsibility for further investigation, regardless of any notice or
information to the contrary, or refuse to accept and make payment upon such
documents if such documents are not in strict compliance with the terms of such
Letter of Credit.

Unless otherwise expressly agreed by the Issuing Bank and the Borrower when a
Letter of Credit is issued and subject to applicable laws, performance under
Letters of Credit by the Issuing Bank, its correspondents, and the beneficiaries
thereof will be governed by the rules of the "International Standby Practices
1998" (ISP98) (or such later revision as may be published by the Institute of
International Banking Law & Practice on any date any Letter of Credit may be
issued) and to the extent not inconsistent therewith, the governing law of this
Agreement set forth in Section 10.5.

               CONDITIONS PRECEDENT TO LOANS AND LETTERS OF CREDIT

            SECTION 3.1. CONDITIONS TO EFFECTIVENESS. The obligations of the

                         REPRESENTATIONS AND WARRANTIES

            The Borrower represents and warrants to the Administrative Agent and
each Lender as follows:

            SECTION 4.1. EXISTENCE; POWER. The Borrower and each of its
Subsidiaries (other than Dormant Companies) (a) is duly organized or formed,
validly existing and in good standing as a corporation, limited liability
company or partnership, as the case may be, under the laws of the jurisdiction
of its organization or formation, (b) has all requisite power and authority to
carry on its business and to execute, deliver and perform its respective
obligations under each Loan Document to which it is a party, and (c) is duly
qualified to transact business, and is in good standing, in each jurisdiction
where such qualification is required, except in the case of clause (c), where a
failure to be so qualified could not reasonably be expected to result in a
Material Adverse Effect.

            SECTION 4.2. ORGANIZATIONAL POWER; AUTHORIZATION. The execution,
delivery and performance by each Loan Party of the Loan Documents to which it is
a party are within such Loan Party's organizational powers and have been duly
authorized by all necessary organizational, and if required, shareholder, member
or partner, action. This Agreement has been duly executed and delivered by the
Borrower, and constitutes, and each other Loan Document to which any Loan Party
is a party, when executed and delivered by such Loan Party, will constitute,
valid and binding obligations of the Borrower or such Loan Party (as the case
may be), enforceable against it in accordance with their respective terms,
except as may be limited by applicable bankruptcy, insolvency, reorganization,
fraudulent conveyance, moratorium, or similar laws affecting the enforcement of
creditors' rights generally and by general principles of equity.

            SECTION 4.3. GOVERNMENTAL AND THIRD PARTY APPROVALS; NO CONFLICTS.
The execution, delivery and performance by the Borrower of this Agreement, and
by each Loan Party of the other Loan Documents to which it is a party (a) do not
require any consent or approval of, registration or filing with, or any action
by, any Governmental Authority or any other Person, except those as have been
obtained or made and are in full force and effect, (b) will not violate any

                                       52
<PAGE>

Requirements of Law applicable to the Borrower or any of its Subsidiaries or any
judgment, order or ruling (c) will not violate or result in a default under any
indenture, material Contractual Obligation binding on the Borrower or any
Subsidiary or any of its respective assets or give rise to a right thereunder to
require any payment to be made by the Borrower or any Subsidiary and (d) will
not result in the creation or imposition of any Lien on any asset of the
Borrower or any Subsidiary, except Liens (if any) created under the Loan
Documents. Other than as described on Schedule 4.3 hereto, no Loan Party is in
default under any Contractual Obligations referenced to in subsection (c)
immediately above.

            SECTION 4.4. FINANCIAL STATEMENTS. The Borrower has furnished to the
Administrative Agent and each Lender (a) the audited consolidated balance sheet
of the Borrower and its Subsidiaries as of December 31, 2003 and the related
audited consolidated statements of income, changes in shareholders' equity and
cash flows for the fiscal year then ended prepared by KPMG accompanied by an
internally prepared consolidating balance sheet of the Borrower and its
Subsidiaries as of such date and related consolidating statements of income,
stockholders' equity and cash flows for the fiscal year then ended and (b) the
unaudited consolidated and consolidating balance sheet of the Borrower and its
Subsidiaries as at the end of June 30, 2004, and the related unaudited
consolidated and consolidating statements of income and cash flows for the
fiscal quarter and year-to-date period then ending, certified by a Responsible
Officer. Such financial statements fairly present in all material respects the
consolidated and consolidating financial condition of the Borrower and its
Subsidiaries as of such dates and the consolidated results of operations for
such periods in conformity with GAAP consistently applied, subject to year-end
audit adjustments and the absence of footnotes in the case of the statements
referred to in subsection (b). Since December 31, 2003, there have been no
changes, events, acts, conditions or occurrences of any nature, singly or in the
aggregate that have had or could reasonably be expected to have a Material
Adverse Effect. Since the December 31, 2003, no Consolidated Party has made any
Restricted Payment except as permitted pursuant to Section 7.5.

            SECTION 4.5. LITIGATION AND ENVIRONMENTAL MATTERS.

            (a) Except for matters set forth on Schedule 4.5(a), no litigation,
investigation or proceeding of or before any arbitrators or Governmental
Authorities is pending against or, to the knowledge of the Borrower, threatened
against or affecting the Borrower or any Subsidiary (i) as to which there is a
reasonable possibility of an adverse determination that could reasonably be
expected to have, either individually or in the aggregate, a Material Adverse
Effect or (ii) which in any manner challenges the validity or enforceability of
this Agreement or any other Loan Document. With respect to any pending
litigation, investigation or proceeding of or before any arbitrators or
Governmental Authorities, no events, acts or conditions have occurred in respect
of or in relation to any such pending litigation, investigation or proceeding
that could reasonably be expected to have, either individually or in the
aggregate, a Material Adverse Effect.

            (b) Except for the matters set forth on Schedule 4.5(b) and except
for matters which could not reasonably be expected to have a Material Adverse
Effect, neither the Borrower nor any Subsidiary (i) has failed to comply with
any Environmental Law or to obtain, maintain or comply with any permit, license
or other approval required under any Environmental Law, (ii) has become

                                       53
<PAGE>

subject to any Environmental Liability, (iii) has received notice of any claim
with respect to any Environmental Liability or (iv) knows of any basis for any
Environmental Liability in each case.

            SECTION 4.6. COMPLIANCE WITH LAWS AND AGREEMENTS. Except where
non-compliance, either singly or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect and except as disclosed on
Schedule 4.3 with respect to clause (b) immediately below, the Borrower and each
Subsidiary is in compliance with (a) all Requirements of Law and all judgments,
decrees and orders of any Governmental Authority, and (b) all Contractual
Obligations of such Consolidated Parties.

            SECTION 4.7. INVESTMENT COMPANY ACT, ETC. Neither the Borrower nor
any Subsidiary is (a) an "investment company" or is "controlled' by an
"investment company" as such terms are defined in, or is subject to regulation
under, the Investment Company Act of 1940, as amended, (b) a "holding company"
as defined in, or subject to regulation under, the Public Utility Holding
Company Act of 1935, as amended or (c) otherwise subject to any other regulatory
scheme limiting its ability to incur debt.

            SECTION 4.8. TAXES. The Borrower and its Subsidiaries and each other
Person for whose taxes the Borrower or any Subsidiary are liable, have timely
filed or caused to be filed all federal, state and foreign tax returns and all
other tax returns or reports that are required to be filed by them, and have
paid all taxes shown to be due and payable on such returns or reports or on any
assessments made against it or its property and all other taxes, fees or other
charges imposed on it or any of its property by any Governmental Authority,
except where the same are currently being contested in good faith by appropriate
proceedings and for which the Borrower or such Subsidiary, as the case may be,
has set aside on its books adequate reserves. The charges, accruals and reserves
on the books of the Borrower and its Subsidiaries in respect of such taxes are
adequate, and no tax liabilities that could be materially in excess of the
amount so provided are anticipated.

            SECTION 4.9. MARGIN REGULATIONS. None of the proceeds of any of the
Loans or Letters of Credit will be used for "purchasing" or "carrying" any
"margin stock" with the respective meanings of each of such terms under
Regulation U of the Board of Governors of the Federal Reserve System as now and
from time to time hereafter in effect or for any purpose that violates the
provisions of Regulation U. Neither the Borrower nor any of its Subsidiaries is
engaged principally, or as one of its important activities, in the business of
extending credit for the purpose of purchasing or carrying "margin stock".

            SECTION 4.10. ERISA. (a) Each Plan is in compliance in all material
respects with the applicable provisions of ERISA, the Code and other Federal or
state laws. Each Plan that is intended to qualify under Section 401(a) of the
Code has received a favorable determination letter from the IRS or an
application for such a letter is currently being processed by the IRS with
respect thereto and, to the best knowledge of the Borrower, nothing has occurred
which would prevent, or cause the loss of, such qualification. The Borrower and
each ERISA Affiliate have made all required contributions to each Plan subject
to Section 412 of the Code, and no application for a funding waiver or an
extension of any amortization period pursuant to Section 412 of the Code has
been made with respect to any Plan.

                                       54
<PAGE>

            (b) There are no pending or, to the best knowledge of the Borrower,
threatened claims, actions or lawsuits, or action by any Governmental Authority,
with respect to any Plan that could reasonably be expected to have a Material
Adverse Effect. There has been no prohibited transaction or violation of the
fiduciary responsibility rules with respect to any Plan that has resulted or
could reasonably be expected to result in a Material Adverse Effect.

            (c) (i) No ERISA Event has occurred or is reasonably expected to
occur; (ii) no Pension Plan has any Unfunded Pension Liability; (iii) neither
the Borrower nor any ERISA Affiliate has incurred, or reasonably expects to
incur, any liability under Title IV of ERISA with respect to any Pension Plan
(other than premiums due and not delinquent under Section 4007 of ERISA); (iv)
neither the Borrower nor any ERISA Affiliate has incurred, or reasonably expects
to incur, any liability (and no event has occurred which, with the giving of
notice under Section 4219 of ERISA, would result in such liability) under
Sections 4201 or 4243 of ERISA with respect to a Multiemployer Plan; and (v)
neither the Borrower nor any ERISA Affiliate has engaged in a transaction that
could be subject to Sections 4069 or 4212(c) of ERISA.

            SECTION 4.11. OWNERSHIP OF PROPERTY.

            (a) The Borrower and each Subsidiary (other than the Dormant
Company) has good title to, or valid leasehold interests in, all of its real and
personal property material to the operation of its business free and clear of
all Liens prohibited by this Agreement.

            (b) The Borrower and each Subsidiary owns, or is licensed, or
otherwise has the right, to use, all patents, trademarks, service marks,
tradenames, copyrights and other intellectual property material to its business,
and the use thereof by the Borrower and the Subsidiaries does not infringe on
the rights of any other Person, except for any such infringements that,
individually or in the aggregate, would not have a Material Adverse Effect.

            (c) The properties of the Borrower and its Subsidiaries are insured
with financially sound and reputable insurance companies which are not
Affiliates of the Borrower, in such amounts with such deductibles and covering
such risks as are customarily carried by companies engaged in similar businesses
and owning similar properties in localities where the Borrower or any applicable
Subsidiary operates.

            SECTION 4.12. DISCLOSURE. The Borrower has disclosed to the
Administrative Agent and the Lenders, all agreements, instruments, and corporate
or other restrictions to which the Borrower or any Subsidiary is subject, and
all other matters known to any of them, with respect to any of the foregoing,
that, individually or in the aggregate, could reasonably be expected to result
in a Material Adverse Effect. No reports (including without limitation all
reports that the Borrower is required to file with the Securities and Exchange
Commission), financial statements, certificates or other information furnished
by or on behalf of the Borrower to the Administrative Agent or any Lender in
connection with the negotiation or syndication of this Agreement or any other
Loan Document or delivered hereunder or thereunder (as modified or supplemented
by any other information so furnished) contains any material misstatement of
fact or omits to state any material

                                       55
<PAGE>

fact necessary to make the statements therein, taken as a whole, in light of the
circumstances under which they were made, not misleading.

            SECTION 4.13. LABOR RELATIONS. There are no strikes, lockouts or
other labor disputes or grievances against the Borrower or any Subsidiary, or,
to the Borrower's knowledge, threatened against or affecting the Borrower or any
Subsidiary, and no significant unfair labor practice, charges or grievances are
pending against the Borrower or any Subsidiary, or to the Borrower's knowledge,
threatened against any of them before any Governmental Authority that could
reasonably be expected to have a Material Adverse Effect. All payments due from
the Borrower or any of its Subsidiaries pursuant to the provisions of any
collective bargaining agreement have been paid or accrued as a liability on the
books of such Borrower or any such Subsidiary, except where the failure to do so
could not reasonably be expected to have a Material Adverse Effect.

            SECTION 4.14. SUBSIDIARIES. As of the Closing Date, Schedule 4.14
sets forth the exact legal name of, the percentage and type of ownership
interest in, the name of the Person who is the record owner of, the jurisdiction

material respects, with the (i) the Trading with the Enemy Act, as amended, and
each of the foreign assets control regulations of the United States Treasury

modification or supplement so that the Lenders shall have the benefit of every
such amendment, modification or supplement. In the event that the terms of any

                                   ARTICLE IX

                            THE ADMINISTRATIVE AGENT

            SECTION 9.1. APPOINTMENT OF ADMINISTRATIVE AGENT. (a) Each Lender
irrevocably appoints SunTrust Bank as the Administrative Agent and authorizes it
to take such actions on its behalf and to exercise such powers as are delegated
to the Administrative Agent under this Agreement and the other Loan Documents,
together with all such actions and powers that are reasonably incidental
thereto. The Administrative Agent may perform any of its duties hereunder or
under the other Loan Documents by or through any one or more sub-agents or
attorneys-in fact appointed by the Administrative Agent. The Administrative
Agent and any such sub-agent or attorney-in-fact may perform any and all of its
duties and exercise its rights and powers through their respective Related
Parties. The exculpatory provisions set forth in this Article shall apply to any
such sub-agent or attorney-in-fact and the Related Parties of the Administrative
Agent and any such

                                      72
<PAGE>

activities in connection with the syndication of the credit facilities provided
for herein as well as activities as Administrative Agent.

            (b) The Issuing Bank shall act on behalf of the Lenders with respect
to any Letters of Credit issued by it and the documents associated therewith
until such time and except for so long as the Administrative Agent may agree at
the request of the Required Lenders to act for the Issuing Bank with respect
thereto; provided, that the Issuing Bank shall have all the benefits and
immunities (i) provided to the Administrative Agent in this Article IX with
respect to any acts taken or omissions suffered by the Issuing Bank in
connection with Letters of Credit issued by it or proposed to be issued by it
and the application and agreements for letters of credit pertaining to the
Letters of Credit as fully as if the term "Administrative Agent" as used in this
Article IX included the Issuing Bank with respect to such acts or omissions and
(ii) as additionally provided in this Agreement with respect to the Issuing
Bank.

            SECTION 9.2. NATURE OF DUTIES OF ADMINISTRATIVE AGENT. The
Administrative Agent shall not have any duties or obligations except those
expressly set forth in this Agreement and the other Loan Documents. Without
limiting the generality of the foregoing, (a) the Administrative Agent shall not
be subject to any fiduciary or other implied duties, regardless of whether a
Default or an Event of Default has occurred and is continuing, (b) the
Administrative Agent shall not have any duty to take any discretionary action or
exercise any discretionary powers, except those discretionary rights and powers
expressly contemplated by the Loan Documents that the Administrative Agent is
required to exercise in writing by the Required Lenders (or such other number or
percentage of the Lenders as shall be necessary under the circumstances as
provided in Section 10.2), and (c) except as expressly set forth in the Loan
Documents, the Administrative Agent shall not have any duty to disclose, and
shall not be liable for the failure to disclose, any information relating to the
Borrower or any of its Subsidiaries that is communicated to or obtained by the
Administrative Agent or any of its Affiliates in any capacity. The
Administrative Agent shall not be liable for any action taken or not taken by
it, its sub-agents or attorneys-in-fact with the consent or at the request of
the Required Lenders (or such other number or percentage of the Lenders as shall
be necessary under the circumstances as provided in Section 10.2) or in the
absence of its own gross negligence or willful misconduct. The Administrative
Agent shall not be responsible for the negligence or misconduct of any
sub-agents or attorneys-in-fact selected by it with reasonable care. The
Administrative Agent shall not be deemed to have knowledge of any Default or
Event of Default unless and until written notice thereof (which notice shall
include an express reference to such event being a "Default" or "Event of
Default" hereunder) is given to the Administrative Agent by the Borrower or any
Lender, and the Administrative Agent shall not be responsible for or have any
duty to ascertain or inquire into (i) any statement, warranty or representation
made in or in connection with any Loan Document, (ii) the contents of any
certificate, report or other document delivered hereunder or thereunder or in
connection herewith or therewith, (iii) the performance or observance of any of
the covenants, agreements, or other terms and conditions set forth in any Loan
Document, (iv) the validity, enforceability, effectiveness or genuineness of any
Loan Document or any other agreement, instrument or document, or (v) the
satisfaction of any condition set forth in Article III or elsewhere in any Loan
Document, other than to confirm receipt of items expressly required to be
delivered to

                                      73
<PAGE>

the Administrative Agent. The Administrative Agent may consult with legal
counsel (including counsel for the Borrower) concerning all matters pertaining
to such duties.

            SECTION 9.3. LACK OF RELIANCE ON THE ADMINISTRATIVE AGENT. Each of
the Lenders, the Swingline Lender and the Issuing Bank acknowledges that it has,
independently and without reliance upon the Administrative Agent or any other
Lender and based on such documents and information as it has deemed appropriate,
made its own credit analysis and decision to enter into this Agreement. Each of
the Lenders, the Swingline Lender and the Issuing Bank also acknowledges that it
will, independently and without reliance upon the Administrative Agent or any
other Lender and based on such documents and information as it has deemed
appropriate, continue to make its own decisions in taking or not taking of any
action under or based on this Agreement, any related agreement or any document
furnished hereunder or thereunder.

            SECTION 9.4. CERTAIN RIGHTS OF THE ADMINISTRATIVE AGENT. If the
Administrative Agent shall request instructions from the Required Lenders with
respect to any action or actions (including the failure to act) in connection
with this Agreement, the Administrative Agent shall be entitled to refrain from
such act or taking such act, unless and until it shall have received
instructions from such Lenders; and the Administrative Agent shall not incur
liability to any Person by reason of so refraining. Without limiting the
foregoing, no Lender shall have any right of action whatsoever against the
Administrative Agent as a result of the Administrative Agent acting or
refraining from acting hereunder in accordance with the instructions of the
Required Lenders where required by the terms of this Agreement.

            SECTION 9.5. RELIANCE BY ADMINISTRATIVE AGENT. The Administrative
Agent shall be entitled to rely upon, and shall not incur any liability for
relying upon, any notice, request, certificate, consent, statement, instrument,
document or other writing believed by it to be genuine and to have been signed,
sent or made by the proper Person. The Administrative Agent may also rely upon
any statement made to it orally or by telephone and believed by it to be made by
the proper Person and shall not incur any liability for relying thereon. The
Administrative Agent may consult with legal counsel (including counsel for the
Borrower), independent public accountants and other experts selected by it and
shall not be liable for any action taken or not taken by it in accordance with
the advice of such counsel, accountants or experts.

            SECTION 9.6. THE ADMINISTRATIVE AGENT IN ITS INDIVIDUAL CAPACITY.
The bank serving as the Administrative Agent shall have the same rights and
powers under this Agreement and any other Loan Document in its capacity as a
Lender as any other Lender and may exercise or refrain from exercising the same
as though it were not the Administrative Agent; and the terms "Lenders",
"Required Lenders", "holders of Notes", or any similar terms shall, unless the
context clearly otherwise indicates, include the Administrative Agent in its
individual capacity. The bank acting as the Administrative Agent and its
Affiliates may accept deposits from, lend money to, and generally engage in any
kind of business with the Borrower or any Subsidiary or Affiliate of the
Borrower as if it were not the Administrative Agent hereunder.

            SECTION 9.7. SUCCESSOR ADMINISTRATIVE AGENT.

                                      74
<PAGE>

            (a) The Administrative Agent may resign at any time by giving notice
thereof to the Lenders and the Borrower. Upon any such resignation or removal,
the Required Lenders shall have the right to appoint a successor Administrative
Agent, subject to the approval by the Borrower provided that no Default or Event
of Default shall exist at such time. If no successor Administrative Agent shall
have been so appointed, and shall have accepted such appointment within 30 days
after the retiring Administrative Agent gives notice of resignation, then the
retiring Administrative Agent may, on behalf of the Lenders and the Issuing
Bank, appoint a successor Administrative Agent, which shall be a commercial bank
organized under the laws of the United States of America or any state thereof or
a bank which maintains an office in the United States, having a combined capital
and surplus of at least $500,000,000.

            (b) Upon the acceptance of its appointment as the Administrative
Agent hereunder by a successor, such successor Administrative Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Administrative Agent, and the retiring Administrative
Agent shall be discharged from its duties and obligations as such under this
Agreement and the other Loan Documents. If within 45 days after written notice
is given of the retiring Administrative Agent's resignation under this Section
9.7 no successor Administrative Agent shall have been appointed and shall have
accepted such appointment, then on such 45th day (i) the retiring Administrative
Agent's resignation shall become effective, (ii) the retiring Administrative
Agent shall thereupon be discharged from its duties and obligations as such
under the Loan Documents and (iii) the Required Lenders shall thereafter perform
all duties of the retiring Administrative Agent under the Loan Documents until
such time as the Required Lenders appoint a successor Administrative Agent as
provided above. After any retiring Administrative Agent's resignation hereunder,
the provisions of this Article IX shall continue in effect for the benefit of
such retiring Administrative Agent and its representatives and agents in respect
of any actions taken or not taken by any of them while it was serving as the
Administrative Agent.

            SECTION 9.8. AUTHORIZATION TO EXECUTE OTHER LOAN DOCUMENTS. Each
Lender hereby authorizes the Administrative Agent to execute on behalf of all
Lenders all Loan Documents other than this Agreement.

notices and other communications hereunder by notice to the other parties
hereto. All such notices and other communications shall, when transmitted by
overnight delivery, or faxed, be effective when actually delivered by overnight
(next-day) delivery, or when transmitted in legible form by facsimile machine,
respectively, or if mailed, upon the third Business Day after the date deposited
into the mails or if delivered, upon delivery; provided, that notices delivered
to the Administrative Agent, the Issuing Bank or the Swingline Bank shall not be

            (b) Any agreement of the Administrative Agent and the Lenders herein
to receive certain notices by telephone or facsimile is solely for the
convenience and at the request of the Borrower. The Administrative Agent and the
Lenders shall be entitled to rely on the authority of any Person purporting to
be a Person authorized by the Borrower to give such notice and the
Administrative Agent and Lenders shall not have any liability to the Borrower or
other Person on account of any action taken or not taken by the Administrative
Agent or the Lenders in reliance upon such telephonic or facsimile notice. The
obligation of the Borrower to repay the Loans and all other Obligations
hereunder shall not be affected in any way or to any extent by any failure of
the Administrative Agent and the Lenders to receive written confirmation of any
telephonic or facsimile notice or the receipt by the Administrative Agent and
the Lenders of a confirmation which is at variance with the terms understood by
the Administrative Agent and the Lenders to be contained in any such telephonic
or facsimile notice.

            SECTION 10.2. WAIVER; AMENDMENTS.

            (a) No failure or delay by the Administrative Agent, the Issuing
Bank or any Lender in exercising any right or power hereunder or any other Loan
Document, and no course of dealing between the Borrower and the Administrative
Agent or any Lender, shall operate as a waiver thereof, nor shall any single or
partial exercise of any such right or power or any abandonment or discontinuance
of steps to enforce such right or power, preclude any other or further exercise
thereof or the exercise of any other right or power hereunder or thereunder. The
rights and remedies of the Administrative Agent, the Issuing Bank and the
Lenders hereunder and under the other Loan Documents are cumulative and are not
exclusive of any rights or remedies provided by law. No waiver of any provision
of this Agreement or any other Loan Document or consent to any departure by the
Borrower therefrom shall in any event be effective unless the same shall be
permitted by paragraph (b) of this Section, and then such waiver or consent
shall be effective only in the specific instance and for the purpose for which
given. Without limiting the generality of the foregoing, the making of a Loan or
the issuance of a Letter of Credit shall not be construed as a waiver of any
Default or Event of Default, regardless of whether the Administrative Agent, any
Lender or the Issuing Bank may have had notice or knowledge of such Default or
Event of Default at the time.

            (b) No amendment or waiver of any provision of this Agreement or the
other Loan Documents, nor consent to any departure by the Borrower therefrom,
shall in any event be effective unless the same shall be in writing and signed
by the Borrower and the Required Lenders or the Borrower and the Administrative
Agent with the consent of the Required Lenders and then such waiver or consent
shall be effective only in the specific instance and for the specific purpose
for which given; provided, that no amendment or waiver shall: (i) except as
expressly provided in Section 2.6, increase the Commitment of any Lender without
the written consent of such Lender, (ii) reduce the principal amount of any Loan
or LC Disbursement or reduce the rate of interest thereon, or reduce any fees
payable hereunder, without the written consent of each Lender affected thereby,
(iii) postpone the date fixed for any payment of any principal of, or interest
on, any Loan or LC Disbursement or interest thereon or any fees hereunder or
reduce the amount of, waive or excuse any such payment, or postpone the
scheduled date for the termination or reduction of any Commitment, without the
written consent of each Lender affected thereby, (iv) change Section 2.24(b) or
(c) in a manner that would alter the pro rata sharing of payments required
thereby, without

                                      77
<PAGE>

the written consent of each Lender, (v) change any of the provisions of this
Section or the definition of "Required Lenders" or any other provision hereof
specifying the number or percentage of Lenders which are required to waive,
amend or modify any rights hereunder or make any determination or grant any
consent hereunder, without the consent of each Lender; and (vi) release any
guarantor or limit the liability of any such guarantor under any guaranty
agreement without the written consent of each Lender; or (vii) release all or
substantially all collateral (if any) securing any of the Obligations, without
the written consent of each Lender; provided, further, that no such agreement
shall amend, modify or otherwise affect the rights, duties or obligations of the
Administrative Agent, the Swingline Bank or the Issuing Bank without the prior
written consent of such Person. No amendment which adversely affects the
Borrower shall be entered into without the Borrower's written consent.

            SECTION 10.3. EXPENSES; INDEMNIFICATION.

            (a) The Borrower shall pay (i) all reasonable out-of-pocket costs
and expenses of the Administrative Agent and its Affiliates, including the
reasonable fees, charges and disbursements of outside counsel for the
Administrative Agent and its Affiliates in connection with the syndication of
the credit facilities provided for herein, the preparation and administration of
the Loan Documents and any amendments, modifications or waivers thereof (whether
or not the transactions contemplated in this Agreement or any other Loan
Document shall be consummated), (ii) all reasonable out-of-pocket expenses
incurred by the Issuing Bank in connection with the issuance, amendment, renewal
or extension of any Letter of Credit or any demand for payment thereunder and
(iii) all out-of-pocket costs and expenses (including, without limitation, the
fees, charges and disbursements of outside counsel actually incurred) incurred
by the Administrative Agent, the Issuing Bank or any Lender in connection with
the enforcement or protection of its rights in connection with this Agreement,
including its rights under this Section, or in connection with the Loans made or
any Letters of Credit issued hereunder, including all such out-of-pocket
expenses incurred during any workout, restructuring or negotiations in respect
of such Loans or Letters of Credit.

            (b) The Borrower shall indemnify the Administrative Agent (and any
sub-agent thereof), each Lender and the Issuing Bank, and each Related Party of
any of the foregoing Persons (each such Person being called an "Indemnitee")
against, and hold each Indemnitee harmless from, any and all losses, claims,
damages, liabilities and related expenses (including the reasonable fees,
charges and disbursements of any counsel for any Indemnitee), incurred by any
Indemnitee or asserted against any Indemnitee by any third party, the Borrower
or any other Loan Party arising out of, in connection with, or as a result of
(i) the execution or delivery of this Agreement, any other Loan Document or any
agreement or instrument contemplated hereby or thereby, the performance by the
parties hereto of their respective obligations hereunder or thereunder or the
consummation of the transactions contemplated hereby or thereby, (ii) any Loan
or Letter of Credit or the use or proposed use of the proceeds therefrom
(including any refusal by the Issuing Bank to honor a demand for payment under a
Letter of Credit if the documents presented in connection with such demand do
not strictly comply with the terms of such Letter of Credit), (iii) any actual
or alleged presence or Release of Hazardous Materials on or from any property
owned or operated by the Borrower or any of its Subsidiaries, or any
Environmental Liability related in any way to the Borrower or any of its
Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation
or proceeding relating to

                                      78
<PAGE>

any of the foregoing, whether based on contract, tort or any other theory,
whether brought by any third party, the Borrower or any other Loan Party, and
regardless of whether any Indemnitee is a party thereto; provided that such
indemnity shall not, as to any Indemnitee, be available to the extent that such
losses, claims, damages, liabilities or related expenses (x) are determined by a
court of competent jurisdiction by final and nonappealable judgment to have
resulted from the gross negligence or willful misconduct of such Indemnitee or
(y) result from a claim brought by the Borrower or any other Loan Party against
an Indemnitee for a material breach of such Indemnitee's obligations hereunder
or under any other Loan Document, if the Borrower or such Loan Party has
obtained a final and nonappealable judgment in its favor on such claim as
determined by a court of competent jurisdiction.

            (c) The Borrower shall pay, and hold the Administrative Agent and
each of the Lenders harmless from and against, any and all present and future
stamp, documentary, and other similar taxes with respect to this Agreement and
any other Loan Documents, any collateral that may be granted by Borrower or a
Subsidiary, or any payments due thereunder, and, if the Borrower fails to pay
any stamp, documentary, and other similar taxes with respect to this Agreement
and any other Loan Documents when due, or fails to remit to the Administrative
Agent or any Lender any such tax with respect to which the Administrative Agent
or such Lender has demanded repayment from the Borrower, the Borrower shall save
the Administrative Agent and each Lender harmless from and against any and all
liabilities with respect to or resulting from any delay or omission to pay such
taxes.

            (d) To the extent that the Borrower fails to pay any amount required
to be paid to the Administrative Agent, the Issuing Bank or the Swingline Lender
under subsections (a), (b) or (c) hereof, each Lender severally agrees to pay to
the Administrative Agent, the Issuing Bank or the Swingline Lender, as the case
may be, such Lender's Pro Rata Share (determined as of the time that the
unreimbursed expense or indemnity payment is sought) of such unpaid amount;
provided, that the unreimbursed expense or indemnified payment, claim, damage,
liability or related expense, as the case may be, was incurred by or asserted
against the Administrative Agent, the Issuing Bank or the Swingline Lender in
its capacity as such.

            (e) To the extent permitted by applicable law, the Borrower shall
not assert, and the Borrower hereby waives, any claim against any Indemnitee, on
any theory of liability, for special, indirect, consequential or punitive
damages (as opposed to actual or direct damages) arising out of, in connection
with or as a result of, this Agreement or any agreement or instrument
contemplated hereby, the transactions contemplated therein, any Loan or any
Letter of Credit or the use of proceeds thereof.

            (f) All amounts due under this Section shall be payable promptly
after written demand therefor.

            SECTION 10.4. 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 assigns
permitted hereby, except that

                                      79
<PAGE>

the Borrower may not assign or otherwise transfer any of its rights or
obligations hereunder without the prior written consent of each Lender (and any
attempted assignment or transfer by the Borrower without such consent shall be
null and void). Nothing in this Agreement, expressed or implied, shall be
construed to confer upon any Person (other than the parties hereto, their
respective successors and assigns permitted hereby and, to the extent expressly
contemplated hereby, the Related Parties of each of the Administrative Agent and
the Lenders) any legal or equitable right, remedy or claim under or by reason of
this Agreement.

            (b) Any Lender may assign to one or more Eligible Assignees all or a
portion of its rights and obligations under this Agreement (including all or a
portion of its Commitment and the Loans and LC Exposure at the time owing to
it); provided that (i) except in the case of an assignment of the entire
remaining amount of the assigning Lender's Commitment and the Loans at the time
owing to it or in the case of an assignment to a Lender, an Affiliate of a
Lender or an Approved Fund with respect to a Lender, the aggregate amount of the
Commitment (which for this purpose includes Loans outstanding thereunder and the
LC Exposure) of the assigning Lender subject to each such assignment (determined
as of the date the Assignment and Acceptance with respect to such assignment is
delivered to the Administrative Agent) shall not be less than $1,000,000, in the
case of any assignment of a Commitment, unless each of the Administrative Agent
and, so long as no Event of Default has occurred and is continuing, the Borrower
otherwise consents (each such consent not to be unreasonably withheld or
delayed), (ii) each partial assignment shall be made as an assignment of a
proportionate part of all the assigning Lender's rights and obligations under
this Agreement with respect to the Loan or the Commitment assigned, except that
this clause (ii) shall not prohibit any Lender from assigning all or a portion
of its rights and obligations among separate Commitments on a non-pro rata
basis, and (iii) the parties to each assignment shall execute and deliver to the
Administrative Agent an Assignment and Acceptance, together with a processing
and recordation fee of $1,000, and the Eligible Assignee, if it shall not be a
Lender, shall deliver to the Administrative Agent an Administrative
Questionnaire. Upon (i) the execution and delivery of the Assignment and
Acceptance by the assigning Lender and assignee Lender, (ii) acceptance and
recording thereof by the Administrative Agent pursuant to paragraph (c) of this
Section, (iii) consent thereof from the Borrower to the extent required pursuant
to this subsection (b) and (iv) if such assignee Lender is a Foreign Lender,
compliance by such Person with Section 2.23(e), from and after the effective
date specified in each Assignment and Acceptance, the Eligible Assignee
thereunder shall be a party hereto and, to the extent of the interest assigned
by such Assignment and Acceptance, have the rights and obligations of a Lender
under this Agreement, and the assigning Lender thereunder shall, to the extent
of the interest assigned by such Assignment and Acceptance, be released from its
obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all of the assigning Lender's rights and obligations under
this Agreement, such Lender shall cease to be a party hereto but shall continue
to be entitled to the benefits of Sections 2.20, 2.21, 2.22 and 10.3). Any
assignment or transfer by a Lender of rights or obligations under this Agreement
that does not comply with this paragraph shall be treated for purposes of this
Agreement as a sale by such Lender of a participation in such rights and
obligations in accordance with paragraph (d) of this Section.

            (c) The Administrative Agent, acting solely for this purpose as an
agent of the Borrower, shall maintain at one of its offices in Atlanta, Georgia
a copy of each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the

                                      80
<PAGE>

Lenders, and the Revolving Commitments of, and principal amount of the Loans
owing to, each Lender pursuant to the terms hereof from time to time (the
"Register"). The entries in the Register shall be conclusive, and the Borrower,
the Administrative Agent and the Lenders may treat each Person whose name is
recorded in the Register pursuant to the terms hereof as a Lender hereunder for
all purposes of this Agreement, notwithstanding notice to the contrary. The
Register shall be available for inspection by the Borrower and any Lender, at
any reasonable time and from time to time upon reasonable prior notice.

            (d) Any Lender may at any time, without the consent of or notice to
the Borrower, the Administrative Agent, the Issuing Bank or the Swingline
Lender, sell participations to one or more banks or other entities (a
"Participant") in all or a portion of such Lender's rights and obligations under
this Agreement (including all or a portion of its Commitment, the Loans owing to
it and its LC Exposure); provided, that (i) such Lender's obligations under this
Agreement shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of its obligations
hereunder, and (iii) the Borrower, the Administrative Agent, the Swingline Bank,
the Issuing Bank and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement and the other Loan Documents. Any agreement or
instrument pursuant to which a Lender sells such a participation shall provide
that such Lender shall retain the sole right to enforce this Agreement and to
approve any amendment, modification or waiver of any provision of this
Agreement; provided that such agreement or instrument may provide that such
Lender will not, without the consent of the Participant, agree to any amendment,
modification or waiver with respect to the following to the extent affecting
such Participant: (A) increase the Revolving Commitment of any Lender without
the written consent of such Lender, (B) reduce the principal amount of any Loan
or reduce the rate of interest thereon, or reduce any fees payable hereunder,
without the written consent of each Lender affected thereby, (C) postpone the
date fixed for any payment of any principal of, or interest on, any Loan or
interest thereon or any fees hereunder or reduce the amount of, waive or excuse
any such payment, or postpone the scheduled date for the termination or
reduction of any Revolving Commitment, without the written consent of each
Lender affected thereby, (D) change Section 2.24(b) or (c) in a manner that
would alter the pro rata sharing of payments required thereby, without the
written consent of each Lender, (E) change any of the provisions of this Section
or the definition of "Required Lenders" or any other provision hereof specifying
the number or percentage of Lenders which are required to waive, amend or modify
any rights hereunder or make any determination or grant any consent hereunder,
without the consent of each Lender; (F) release any guarantor or limit the
liability of any such guarantor under any guaranty agreement without the written
consent of each Lender except to the extent such release is expressly provided
under the terms of the Guaranty Agreement; or (G) release all or substantially
all collateral (if any) securing any of the Obligations. Subject to paragraph
(e) of this Section, the Borrower agrees that each Participant shall be entitled
to the benefits of Sections 2.21, 2.22 and 2.23 to the same extent as if it were
a Lender and had acquired its interest by assignment pursuant to paragraph (b)
of this Section, provided such Participant agres to be subject to Section 2.25
as though it were a Lender hereunder. To the extent permitted by law, each
Participant also shall be entitled to the benefits of Section 10.7 as though it
were a Lender, provided such Participant agrees to be subject to Section 10.7 as
though it were a Lender.

                                      81
<PAGE>

            (e) A Participant shall not be entitled to receive any greater
payment under Section 2.21 and Section 2.23 than the applicable Lender would
have been entitled to receive with respect to the participation sold to such
Participant, unless the sale of the participation to such Participant is made
with the Borrower's prior written consent. A Participant that would be a Foreign
Lender if it were a Lender shall not be entitled to the benefits of Section 2.23
unless the Borrower is notified of the participation sold to such Participant
and such Participant agrees, for the benefit of the Borrower, to comply with
Section 2.23(e) as though it were a Lender.

            (f) Any Lender may at any time pledge or assign a security interest
in all or any portion of its rights under this Agreement to secure obligations
of such Lender, including without limitation, any pledge or assignment to secure
obligations to a Federal Reserve Bank; provided, that no such pledge or
assignment of a security interest shall release a Lender from any of its
obligations hereunder or substitute any such pledgee or assignee for such Lender
as a party hereto.

            SECTION 10.5. GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF
PROCESS.

            (a) This Agreement and the other Loan Documents shall be construed
in accordance with and be governed by the law (without giving effect to the
conflict of law principles thereof) of the State of Georgia.

            (b) The Borrower hereby irrevocably and unconditionally submits, for
itself and its property, to the non-exclusive jurisdiction of the United States
District Court of the Northern District of Georgia, and of any state court of
the State of Georgia located in Fulton County and any appellate court from any
thereof, in any action or proceeding arising out of or relating to this
Agreement or any other Loan Document or the transactions contemplated hereby or
thereby, or for recognition or enforcement of any judgment, and each of the
parties hereto hereby irrevocably and unconditionally agrees that all claims in
respect of any such action or proceeding may be heard and determined in such
Georgia state court or, to the extent permitted by applicable law, such Federal
court. Each of the parties hereto agrees that a final judgment in any such
action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
Nothing in this Agreement or any other Loan Document shall affect any right that
the Administrative Agent, the Issuing Bank or any Lender may otherwise have to
bring any action or proceeding relating to this Agreement or any other Loan
Document against the Borrower or its properties in the courts of any
jurisdiction in which the property that is the subject of such action or
proceeding is located.

            (c) The Borrower irrevocably and unconditionally waives any
objection which it may now or hereafter have to the laying of venue of any such
suit, action or proceeding described in paragraph (b) of this Section and
brought in any court referred to in paragraph (b) of this Section. Each of the
parties hereto irrevocably waives, to the fullest extent permitted by applicable
law, the defense of an inconvenient forum to the maintenance of such action or
proceeding in any such court.

            (d) Each party to this Agreement irrevocably consents to the service
of process in the manner provided for notices in Section 10.1. Nothing in this
Agreement or in any other Loan

                                      82
<PAGE>

Document will affect the right of any party hereto to serve process in any other
manner permitted by law.

            SECTION 10.6. WAIVER OF JURY TRIAL. EACH PARTY HERETO IRREVOCABLY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE
TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF
THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED
HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH
PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY
OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, AND (B)
ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER
INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE
MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

            SECTION 10.7. RIGHT OF SETOFF. In addition to any rights now or
hereafter granted under applicable law and not by way of limitation of any such
rights, each Lender and the Issuing Bank shall have the right, at any time or
from time to time upon the occurrence and during the continuance of an Event of
Default, without prior notice to the Borrower, any such notice being expressly
waived by the Borrower to the extent permitted by applicable law, to set off and
apply against all deposits (general or special, time or demand, provisional or
final) of the Borrower at any time held or other obligations at any time owing
by such Lender and the Issuing Bank to or for the credit or the account of the
Borrower against any and all Obligations held by such Lender or the Issuing
Bank, as the case may be, irrespective of whether such Lender or the Issuing
Bank shall have made demand hereunder and although such Obligations may be
unmatured. Each Lender and the Issuing Bank agree promptly to notify the
Administrative Agent and the Borrower after any such set-off and any application
made by such Lender and the Issuing Bank, as the case may be; provided, that the
failure to give such notice shall not affect the validity of such set-off and
application.

            SECTION 10.8. COUNTERPARTS; INTEGRATION. This Agreement may be
executed by one or more of the parties to this Agreement on any number of
separate counterparts (including by telecopy), and all of said counterparts
taken together shall be deemed to constitute one and the same instrument. This
Agreement, the other Loan Documents, and any separate letter agreement(s)
relating to any fees payable to the Administrative Agent constitute the entire
agreement among the parties hereto and thereto regarding the subject matters
hereof and thereof and supersede all prior agreements and understandings, oral
or written, regarding such subject matters.

            SECTION 10.9. SURVIVAL. All covenants, agreements, representations
and warranties made by the Borrower herein and in the certificates or other
instruments delivered in connection with or pursuant to this Agreement shall be
considered to have been relied upon by the other parties hereto and shall
survive the execution and delivery of this Agreement and the making of any Loans
and issuance of any Letters of Credit, regardless of any investigation made by
any such other party or on its behalf and notwithstanding that the
Administrative Agent, the Issuing Bank or any Lender may

                                      83
<PAGE>

have had notice or knowledge of any Default or incorrect representation or
warranty at the time any credit is extended hereunder, and shall continue in
full force and effect as long as the principal of or any accrued interest on any
Loan or any fee or any other amount payable under this Agreement is outstanding
and unpaid or any Letter of Credit is outstanding and so long as the Commitments
have not expired or terminated. The provisions of Sections 2.21, 2.22, 2.23, and
10.3 and Article IX shall survive and remain in full force and effect regardless
of the consummation of the transactions contemplated hereby, the repayment of
the Loans, the expiration or termination of the Letters of Credit and the
Commitments or the termination of this Agreement or any provision hereof. All
representations and warranties made herein, in the certificates, reports,
notices, and in other documents delivered pursuant to this Agreement shall
survive the execution and delivery of this Agreement and the other Loan
Documents, and the making of the Loans and the issuance of the Letters of
Credit.

            SECTION 10.10. SEVERABILITY. Any provision of this Agreement or any
other Loan Document held to be illegal, invalid or unenforceable in any
jurisdiction, shall, as to such jurisdiction, be ineffective to the extent of
such illegality, invalidity or unenforceability without affecting the legality,
validity or enforceability of the remaining provisions hereof or thereof; and
the illegality, invalidity or unenforceability of a particular provision in a
particular jurisdiction shall not invalidate or render unenforceable such
provision in any other jurisdiction.

            SECTION 10.11. INTEREST RATE LIMITATION. Notwithstanding anything
herein to the contrary, if at any time the interest rate applicable to any Loan,
together with all fees, charges and other amounts which may be treated as
interest on such Loan under applicable law (collectively, the "CHARGES"), shall
exceed the maximum lawful rate of interest (the "MAXIMUM RATE") which may be
contracted for, charged, taken, received or reserved by a Lender holding such

                                     FORM OF
                          SUBSIDIARY GUARANTY AGREEMENT

      SUBSIDIARY GUARANTY AGREEMENT dated as of December 10, 2004 (this
"Guaranty"), among each of the Subsidiaries listed on Schedule I hereto (each
such Subsidiary individually, a "Guarantor" and collectively, the "Guarantors")
of EMS Technologies, Inc., a Georgia corporation (the "Borrower"), and SUNTRUST
BANK, a Georgia banking corporation as Administrative Agent (the "Administrative
Agent") for the Lenders (as defined in the Credit Agreement referred to below).

      Reference is made to the U.S. Revolving Credit Agreement dated as of
December 10, 2004 (as amended, supplemented or otherwise modified from time to
time, the "Credit Agreement"), among the Borrower, the Lenders from time to time
party thereto (the "Lenders"), and the Administrative Agent for the Lenders.

       The Lenders have agreed to make Loans to the Borrower, and the Issuing
Bank has agreed to issue Letters of Credit for the account of the Borrower,
pursuant to, and upon the terms and subject to the conditions specified in, the
Credit Agreement. Each of the Guarantors is a direct or indirect domestic
Subsidiary of the Borrower and acknowledges that it will derive substantial
benefit from the making of the Loans by the Lenders, and the issuance of the
Letters of Credit by the Issuing Bank. The obligations of the Lenders to make
Loans and of the Issuing Bank to issue Letters of Credit are conditioned on,
among other things, the execution and delivery by the Guarantors of a Subsidiary
Guaranty Agreement in the form hereof. As consideration therefor and in order to
induce the Lenders to make Loans and the Issuing Bank to issue Letters of
Credit, the Guarantors are willing to execute this Guaranty.

      Accordingly, the parties hereto agree as follows:

      1. DEFINITIONS. The term "Obligations" and all other capitalized terms
used herein without definition shall have the respective meanings provided
therefor in the Credit Agreement.

      2. GUARANTY OF PAYMENT AND PERFORMANCE. Each Guarantor hereby guarantees,
jointly and severally, to the Lenders, the Administrative Agent and the
Collateral Agent, the full and punctual payment when due (whether at stated
maturity, by required pre-payment, by acceleration or otherwise), as well as the
performance, of all of the Obligations, including all such which would become
due but for the operation of the automatic stay pursuant to Section 362(a) of
the Bankruptcy Code of 1978, as amended (the "Bankruptcy Code") and the
operation of Sections 502(b) and 506(b) of the Bankruptcy Code. This Guaranty is
an absolute, unconditional and continuing guaranty of the full and punctual
payment and performance of all of the Obligations and not of their
collectibility only and is in no way conditioned upon any requirement that the
Administrative Agent, any Lender or the Collateral Agent first attempt to
collect any of the Obligations from the Borrower or resort to any collateral
security or other means of obtaining payment. The obligations of each Guarantor

                                       E-1
<PAGE>

hereunder with respect to such Obligations shall be primary and shall, upon
demand by the Administrative Agent or the Collateral Agent, as applicable,
following an Event of Default, become immediately due and payable to the
Administrative Agent, for the benefit of the Lenders, the Administrative Agent
and the Collateral Agent, without demand or notice of any nature, all of which
are expressly waived by each Guarantor. Payments by the Guarantors hereunder may
be required by the Administrative Agent on any number of occasions. All payments
by any Guarantor hereunder shall be made to the Administrative Agent or the
Collateral Agent, as applicable, in the manner and at the place of payment
specified therefor in the Credit Agreement, for the account of the Lenders and
the Administrative Agent.

      3. GUARANTORS' AGREEMENT TO PAY ENFORCEMENT COSTS, ETC. (a) Each Guarantor
further agrees, as the principal obligor and not as a guarantor only, to pay to
the Administrative Agent or the Collateral Agent, as applicable, on demand, all
reasonable costs and expenses (including court costs and reasonable legal
expenses) incurred or expended by the Administrative Agent, the Collateral Agent
or any Lender in connection with the Obligations and this Guaranty, together
with interest on amounts recoverable under this Section 3 from the time when
such amounts become due until payment, whether before or after judgment, at the
rate of interest after an Event of Default set forth in the Credit Agreement,
provided that if such interest exceeds the maximum amount permitted to be paid
under applicable law, then such interest shall be reduced to such maximum
permitted amount.

        (b) Each Guarantor further agrees, as the principal obligor and not as a
guarantor only, to pay to the Administrative Agent or the Collateral Agent, as
applicable, on demand, all costs and expenses (including court costs and legal
expenses actually incurred) incurred or expended by the Administrative Agent,
the Collateral Agent or any Lender in connection with the enforcement of the
Obligations and this Guaranty, together with interest on amounts recoverable
under this Section 3 from the time when such amounts become due until payment,
whether before or after judgment, at the rate of interest after an Event of
Default set forth in the Credit Agreement, provided that if such interest
exceeds the maximum amount permitted to be paid under applicable law, then such
interest shall be reduced to such maximum permitted amount.

      4. WAIVERS BY GUARANTORS; LENDERS' FREEDOM TO ACT. Each Guarantor agrees
that the Obligations will be paid and performed strictly in accordance with
their respective terms, regardless of any law, regulation or order now or
hereafter in effect in any jurisdiction affecting any of such terms or the
rights of the Administrative Agent, the Collateral Agent or any Lender with
respect thereto. Each Guarantor waives, except to the extent that any such
waiver would be expressly prohibited by law, promptness, diligences,
presentment, demand, protest, notice of acceptance, notice of any Obligations
incurred and all other notices of any kind, all defenses which may be available
by virtue of any valuation, stay, moratorium law or other similar law now or
hereafter in effect, any right to require the marshalling of assets of the
Borrower or any other entity or other person primarily or secondarily liable
with respect to any of the Obligations, and all suretyship defenses generally.
Without limiting the generality of the foregoing, each Guarantor agrees to the
provisions of any instrument evidencing, securing or otherwise executed in
connection with any Obligation and agrees that the obligations of the Guarantors
hereunder shall not be released or discharged, in whole or in

                                      -2-
<PAGE>

part, or otherwise affected by (i) the failure of the Administrative Agent, the
Collateral Agent or any Lender to assert any claim or demand or to enforce any
right or remedy against the Borrower or any other entity or other Person
primarily or secondarily liable with respect to any of the Obligations; (ii) any
extensions, compromise, refinancing, consolidation or renewals of any
Obligation; (iii) any change in the time, place or manner of payment of any of
the Obligations or any rescissions, waivers, compromise, refinancing,
consolidation or other amendments or modifications of any of the terms or
provisions of the Credit Agreement, the Notes, the other Loan Documents or any
other agreement evidencing, securing or otherwise executed in connection with
any of the Obligations, (iv) the addition, substitution or release of any entity
or other Person primarily or secondarily liable for any Obligation; (v) the
adequacy of any rights which the Administrative Agent, the Collateral Agent or
any Lender may have against any collateral security or other means of obtaining
repayment of any of the Obligations; (vi) the impairment of any collateral
securing any of the Obligations, including without limitation the failure to
perfect or preserve any rights which the Administrative Agent, the Collateral
Agent or any Lender might have in such collateral security or the substitution,
exchange, surrender, release, loss or destruction of any such collateral
security; or (vii) any other act or omission which might in any manner or to any
extent vary the risk of any Guarantor or otherwise operate as a release or
discharge of any Guarantor, all of which may be done without notice to any
Guarantor. To the fullest extent permitted by law, each Guarantor hereby
expressly waives any and all rights or defenses arising by reason of (A) any
"one action" or "anti-deficiency" law, which would otherwise prevent the
Administrative Agent, the Collateral Agent or any Lender from bringing any
action, including any claim for a deficiency, or exercising any other right or
remedy (including any right of set-off), against such Guarantor before or after
the Administrative Agent's, the Collateral Agent's or such Lender's commencement
or completion of any foreclosure action, whether judicially, by exercise of
power of sale or otherwise, or (B) any other law which in any other way would
otherwise require any election of remedies by the Administrative Agent or any
Lender.

      5. UNENFORCEABILITY OF OBLIGATIONS AGAINST BORROWER. If for any reason the
Borrower has no legal existence or is under no legal obligation to discharge any
of the Obligations, or if any of the Obligations have become irrecoverable from
the Borrower by reason of the Borrower's insolvency, bankruptcy or
reorganization or by other operation of law or for any other reason, this
Guaranty shall nevertheless be binding on each Guarantor to the same extent as
if such Guarantor at all times had been the principal obligor on all such
Obligations. In the event that acceleration of the time for payment of any of
the Obligations is stayed upon the insolvency, bankruptcy or reorganization of
the Borrower, or for any other reason, all such amounts otherwise subject to
acceleration under the terms of the Credit Agreement, the Notes, the other Loan
Documents or any other agreement evidencing, securing or otherwise executed in
connection with any Obligation shall be immediately due and payable by the
Guarantors.

      6. SUBROGATION; SUBORDINATION.

            6.1. WAIVER OF RIGHTS AGAINST BORROWER. Until the final payment in
      cash and performance in full of all of the Obligations, no Guarantor shall
      exercise, and each Guarantor hereby waives, any rights against the
      Borrower arising as a result of payment by such Guarantor hereunder, by
      way of subrogation, reimbursement, restitution, contribution or

                                      -3-
<PAGE>

      otherwise, and no Guarantor will prove any claim in competition with
      the Administrative Agent or any Lender in respect of any payment hereunder
      in any bankruptcy, insolvency or reorganization case or proceedings of any
      nature; no Guarantor will claim any setoff, recoupment or counterclaim
      against the Borrower in respect of any liability of such Guarantor to the
      Borrower; and each Guarantor waives any benefit of and any right to
      participate in any collateral security which may be held by the
      Administrative Agent or any Lender.

            6.2 SUBORDINATION. The payment of any amounts due with respect to
      any indebtedness of the Borrower for money borrowed or credit received now
      or hereafter owed to any Guarantor is hereby subordinated to the prior
      payment in full in cash of all of the Obligations. Each Guarantor agrees
      that, if an Event of Default exists, no Guarantor will demand, sue for or
      otherwise attempt to collect any such indebtedness of the Borrower to any
      Guarantor until all of the Obligations shall have been paid in full. If,
      notwithstanding the foregoing sentence, any Guarantor shall collect,
      enforce or receive any amounts in respect of such indebtedness while any
      Obligations are still outstanding, such amounts shall be collected,
      enforced and received by such Guarantor as trustee for the Lenders, the
      Collateral Agent and the Administrative Agent and be paid over to the
      Administrative Agent or the Collateral Agent, for the benefit of the
      Lenders, the Collateral Agent and the Administrative Agent, on account of
      the Obligations without affecting in any manner the liability of any
      Guarantor under the other provisions of this Guaranty.

            6.3 PROVISIONS SUPPLEMENTAL. The provisions of this Section 6 shall
      be supplemental to and not in derogation of any rights and remedies of the
      Lenders and the Administrative Agent or the Collateral Agent under any
      separate subordination agreement which the Administrative Agent or the
      Collateral Agent may at any time and from time to time enter into with any
      Guarantor for the benefit of the Lenders, the Collateral Agent and the
      Administrative Agent.

      7. SECURITY; SETOFF. Each Guarantor grants to the Administrative Agent and
each of the Lenders, as security for the full and punctual payment and
performance of all of the Guarantors' obligations hereunder, a continuing lien
on and security interest in all securities or other property belonging to such
Guarantor now or hereafter held by the Administrative Agent or such Lender and
in all deposits (general or special, time or demand, provisional or final) and
other sums credited by or due from the Administrative Agent or such Lender to
such Guarantor or subject to withdrawal by such Guarantor. Regardless of the
adequacy of any collateral security or other means of obtaining payment of any
of the Obligations and in addition to any rights now or hereafter granted under
applicable law and not by way of limitation of any such rights, after the
occurrence and during the continuance of an Even of Default, the Administrative
Agent and the Lenders are hereby authorized at any time and from time to time,
without notice to any Guarantor (any such notice being expressly waived by each
Guarantor) and to the fullest extent permitted by law, to set off and apply such
deposits and other sums against the obligations of the Guarantors under this
Guaranty, whether or not the Administrative Agent or such Lender shall have made
any demand under this Guaranty and although such obligations may be contingent
or unmatured.

                                      -4-
<PAGE>

      8. FURTHER ASSURANCES. Each Guarantor agrees that it will from time to
time, at the request of the Administrative Agent, do all such things and execute
all such documents as the Administrative Agent may reasonably consider necessary
or desirable to give full effect to this Guaranty and to perfect and preserve
the rights and powers of the Lenders, the Collateral Agent and the
Administrative Agent hereunder. Each Guarantor acknowledges and confirms that
such Guarantor itself has established its own adequate means of obtaining from
the Borrower on a continuing basis all information desired by such Guarantor
concerning the financial condition of the Borrower and that such Guarantor will
look to the Borrower and not to the Administrative Agent or any Lender in order
for such Guarantor to keep adequately informed of changes in the Borrower's
financial condition.

      9. TERMINATION; REINSTATEMENT. This Guaranty shall terminate upon (a)
payment in full in cash of the Obligations (other than contingent reimbursement
and indemnification obligations to the extent no unsatisfied claim has been
asserted), (b) termination of the Commitments under the Credit Agreement, and
(c) either termination of all Letters of Credit or delivery by the Borrower of
cash collateral or back-up letters of credit issued by a bank acceptable to the
Issuing Bank in favor of the Issuing Bank, in amounts and on terms satisfactory
to the Issuing Bank, covering all obligations of the Lenders with respect to all
Letters of Credit. This Guaranty shall continue to be effective or be reinstated
if at any time any payment made or value received with respect to any Obligation
is rescinded or must otherwise be returned by the Administrative Agent or any
Lender upon the insolvency, bankruptcy or reorganization of the Borrower, or
otherwise, all as though such payment had not been made or value received.

      10. SUCCESSORS AND ASSIGNS. This Guaranty shall be binding upon each
Guarantor, its successors and assigns, and shall inure to the benefit of the
Administrative Agent and the Lenders and their respective successors,
transferees and assigns. Without limiting the generality of the foregoing
sentence, each Lender may assign or otherwise transfer its interest under the
Credit Agreement, Notes, its interest under the other Loan Documents or any
other agreement or note held by it evidencing, securing or otherwise executed in
connection with the Obligations, or sell participations in any interest therein,
to any other Person, and such other Person shall thereupon become vested, to the
extent set forth in the agreement evidencing such assignment, transfer or
participation, with all the rights in respect thereof granted to such Lender
herein, all in accordance with Section 10.4 of the Credit Agreement. No
Guarantor may assign any of its obligations hereunder.

      11. AMENDMENTS AND WAIVERS. No amendment or waiver of any provision of
this Guaranty nor consent to any departure by any Guarantor therefrom shall be
effective unless the same shall be in writing and otherwise in accordance with
Section 10.2 of the Credit Agreement. No failure on the part of Administrative
Agent or any Lender to exercise, and no delay in exercising, any right hereunder
shall operate as a waiver thereof; nor shall any single or partial exercise of
any right hereunder preclude any other or further exercise thereof or the
exercise of any other right.

<PAGE>

      12. NOTICES. All communications and notices hereunder shall be in writing
and given as provided in Section 10.1 of the Credit Agreement. All
communications and notices hereunder to each Guarantor shall be given to it at
its address set forth on Schedule I attached hereto.

      13. GOVERNING LAW; CONSENT TO JURISDICTION. THIS GUARANTY SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF GEORGIA.
Each Guarantor agrees that any suit for the enforcement of this Guaranty may be
brought in the courts of the State of Georgia or any federal court sitting
therein and consents to the nonexclusive jurisdiction of such court and to
service of process in any such suit being made upon such Guarantor by mail at
the address specified by reference in Section 12. Each Guarantor hereby waives
any objection that it may now or hereafter have to the venue of any such suit or
any such court or that such suit was brought in an inconvenient court.

      14. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES ITS RIGHTS TO A
JURY TRIAL WITH RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN
CONNECTION WITH THIS GUARANTY, ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THE
PERFORMANCE OF ANY OF SUCH RIGHTS OR OBLIGATIONS. Each Guarantor (a) certifies
that neither the Administrative Agent or any Lender, nor any representative,
agent or attorney of the Administrative Agent, or any Lender, has represented,
expressly or otherwise, that the Administrative Agent or any Lender would not,
in the event of litigation, seek to enforce the foregoing waivers and (b)
acknowledges that, in entering into the Credit Agreement and the other Loan
Documents to which the Administrative Agent or any Lender is a party, the
Administrative Agent and the Lenders are relying upon, among other things, the
waivers and certifications contained in this Section 14.

      15. LIMITATION ON GUARANTOR LIABILITY. (a) It is the intent of each
Guarantor, the Lenders, the Collateral Agent and the Administrative Agent that
each Guarantor's maximum liability hereunder shall not be in excess of:

            (i) in a Proceeding (as defined below) commenced by or against such
      Guarantor under the Bankruptcy Code, on or within one year from the date
      on which any of such Guarantor's obligations hereunder are incurred, the
      maximum amount which would not otherwise cause such Guarantor's
      obligations hereunder to be avoidable or unenforceable against such
      Guarantor under (A) Section 548 of the Bankruptcy Code, or (B) any state
      fraudulent transfer or fraudulent conveyance act or statute applied in
      such case or proceeding by virtue of Section 544 of the Bankruptcy Code;
      or

            (ii) in a Proceeding commenced by or against such Guarantor under
      the Bankruptcy Code subsequent to one year from the date on which any of
      such Guarantor's obligations hereunder are incurred, the maximum amount
      which would not otherwise cause such Guarantor's obligations to be
      avoidable or unenforceable against such Guarantor under any state
      fraudulent transfer or fraudulent conveyance act or statute applied in any
      such case or proceeding by virtue of Section 544 of the Bankruptcy Code;
      or

                                      -6-
<PAGE>

            (iii) in a Proceeding commenced by or against such Guarantor under
      any law, statute or regulation other than the Bankruptcy Code (including,
      without limitation, any other bankruptcy, reorganization, arrangement,
      moratorium, readjustment of debt, dissolution, liquidation or similar
      debtor relief laws), the maximum amount which would not otherwise cause
      such Guarantor's obligations hereunder to be avoidable or unenforceable
      against such Guarantor under such law, statute or regulation, including,
      without limitation, any state fraudulent transfer or fraudulent conveyance
      act or statute applied in any such case or proceeding.

(The substantive laws under which the possible avoidance or unenforceability of
the Guarantors' obligations hereunder shall be determined in any such case or
proceeding shall hereinafter be referred to as the "Avoidance Provisions".
"Proceeding" means a voluntary case commenced by any Guarantor concerning itself
under the Bankruptcy Code or any other applicable bankruptcy laws; or any
involuntary case commenced against any Guarantor; or the appointment of, or
taking charge by, a custodian (as defined in the Bankruptcy Code or any other
applicable bankruptcy laws) for all or any substantial part of the property of
any Guarantor, or any other proceedings commenced by any Guarantor under any
reorganization, arrangement, adjustment of debt, relief of debtor, dissolution,
insolvency or liquidation or similar law of any jurisdiction whether now or
hereafter in effect relating to such Guarantor, or any such proceeding commenced
against such Guarantor, or the adjudication of any Guarantor to be insolvent or
bankrupt; or any order of relief or other order approving any such case or
proceeding is entered; or any appointment of any custodian or the like suffered
by any Guarantor for it or any substantial part of its property; or a general
assignment by any Guarantor for the benefit of its creditors).

      (b) To the end set forth in Section 15(a), but only to the extent that
such Guarantor's obligations hereunder would otherwise be subject to avoidance
under the Avoidance Provisions, if such Guarantor is not deemed to have received
valuable consideration, fair value or reasonably equivalent value for such
obligations, or if such obligations would render such Guarantor insolvent, or
leave such Guarantor with an unreasonably small capital to conduct its business,
or cause such Guarantor to have incurred debts (or to have intended to have
incurred debts) beyond its ability to pay such debts as they mature, in each
case as of the time any of such Guarantor's obligations hereunder are deemed to
have been incurred under the Avoidance Provisions, the maximum Obligations for
which such Guarantor shall be liable hereunder shall be reduced to that amount
which, after giving effect thereto, would not cause such Guarantor's obligations
hereunder, as so reduced, to be subject to avoidance under the Avoidance
Provisions.

      (c) This Section 15 shall be applicable only in connection with a
Proceeding brought by or against any Guarantor and is intended solely to
preserve the rights of the Administrative Agent, the Collateral Agent and
Lenders to the maximum extent that would not cause the obligations of such
Guarantor to be subject to avoidance under the Avoidance Provisions in
connection with any such Proceeding. No Guarantor nor any other Person shall
have any right or claim under this Section 15 as against the Administrative
Agent, the Collateral Agent or Lenders that would not otherwise be available to
such Guarantor or such other Person outside of any Proceeding.

                                      -7-
<PAGE>

      16. JOINT AND SEVERAL GUARANTEED OBLIGATIONS. This Guaranty shall be
continuing, absolute and unconditional and shall remain in full force and effect
as to each Guarantor hereunder, despite the fact that a Guarantor shall be
dissolved or liquidated or shall otherwise be released or discharged from its
obligations hereunder; the obligations of the Guarantors being joint and several
and each of the Guarantors is liable for the full amount of the Obligations.

      17. CONTRIBUTION.

            17.1. CONTRIBUTION AND SUBROGATION. Each Guarantor (a "Contributing
      Guarantor") agrees (subject to Section 17.2) that, in the event a payment
      shall be made by any other Guarantor under this Guaranty (the "Claiming
      Guarantor"), the Contributing Guarantor shall indemnify the Claiming
      Guarantor in an amount equal to the amount of such payment in each case
      multiplied by a fraction of which the numerator shall be the net worth of
      the Contributing Guarantor on the date hereof and the denominator shall be
      the aggregate net worth of all the Guarantors on the date hereof (or, in
      the case of any Guarantor becoming a party hereto pursuant to Section 18,
      the date of the Supplement hereto executed and delivered by such
      Guarantor). Any Contributing Guarantor making any payment to a Claiming
      Guarantor pursuant to this Section 17.1 shall be subrogated to the rights
      of such Claiming Guarantor.

            17.2. SUBORDINATION. Notwithstanding any provision of this Guaranty
      to the contrary, all rights of the Guarantors under Section 17.1 and all
      other rights of indemnity, contribution or subrogation under applicable
      law or otherwise shall be fully subordinated to the indefeasible payment
      in full in cash of the Obligations. No failure on the part of the Borrower
      or any Guarantor to make the payments required under applicable law or
      otherwise shall in any respect limit the obligations and liabilities of
      any Guarantor with respect to its obligations hereunder, and each
      Guarantor shall remain liable for the full amount of the obligations of
      such Guarantor hereunder.

      18. ADDITIONAL GUARANTORS. Pursuant to Section 5.10 of the Credit
Agreement, each Subsidiary Loan Party that was not in existence or that was not
owned (directly or indirectly) by the Borrower on the date of the Credit
Agreement is required to enter into this Guaranty as a Guarantor upon becoming a
Subsidiary Loan Party. Upon execution and delivery after the date hereof by the
Administrative Agent and such Subsidiary of an instrument in the form of Annex
1, such Subsidiary shall become a Guarantor hereunder with the same force and
effect as if originally named as a Guarantor herein. The execution and delivery
of any instrument adding an additional Guarantor as a party to this Guaranty
shall not require the consent of any other Guarantor hereunder. The rights and
obligations of each Guarantor hereunder shall remain in full force and effect
notwithstanding the addition of any new Guarantor as a party to this Guaranty.

      19. MISCELLANEOUS. This Guaranty constitutes the entire agreement of each
Guarantor with respect to the matters set forth herein. The rights and remedies
herein provided are cumulative and not exclusive of any remedies provided by law
or any other agreement, and this Guaranty shall be in addition to any other
guaranty of or collateral security for any of the Obligations. The

                                      -8-
<PAGE>

invalidity or unenforceability of any one or more sections of this Guaranty
shall not affect the validity or enforceability of its remaining provisions.
Captions are for the ease of reference only and shall not affect the meaning of
the relevant provisions. The meanings of all defined terms used in this Guaranty
shall be equally applicable to the singular and plural forms of the terms
defined.

      20. COUNTERPARTS. This Guaranty may be executed in any number of
counterparts and by the different parties hereto on separate counterparts, each
of which shall be deemed an original, but all of such counterparts shall
constitutes one and the same agreement.

                                 ANNEX 1 TO THE
                          SUBSIDIARY GUARANTY AGREEMENT

            SUPPLEMENT NO. _____ dated as of ____________________ (this
"Supplement"), to the Subsidiary Guaranty Agreement (the "Guaranty") dated as of
December 10, 2004 among each of the Subsidiaries listed on Schedule I thereto
(each such Subsidiary individually, a "Guarantor" and collectively, the
"Guarantors") of EMS TECHNOLOGIES, INC., a Georgia corporation (the "Borrower")
and SUNTRUST BANK, a Georgia banking corporation, as Administrative Agent (the
"Administrative Agent") for the Lenders (as defined in the Credit Agreement
referred to below).

            A. Reference is made to the U.S. Revolving Credit Agreement dated as
of December 10, 2004 (as amended, supplemented or otherwise modified from time
to time, the "Credit Agreement"), among the Borrower, the Lenders from time to
time party thereto (the "Lenders") and the Administrative Agent. Capitalized
terms used herein and not otherwise defined herein shall have the meanings
assigned to such terms in the Credit Agreement.

            B. The Guarantors have entered into the Guaranty in order to induce
the Lenders to make Loans and the Issuing Bank to issue Letters of Credit.
Pursuant to Section 5.10 of the Credit Agreement, each Subsidiary Loan Party
that was not in existence or not a Subsidiary Loan Party on the date of the
Credit Agreement is required to enter into the Guaranty as a Guarantor upon
becoming a Subsidiary Loan Party. Section 18 of the Guaranty provides that
additional Subsidiaries of the Borrower may become Guarantors under the Guaranty
by execution and delivery of an instrument in the form of this Supplement. The
undersigned Subsidiary of the Borrower (the "New Guarantor") is executing this
Supplement in accordance with the requirements of the Credit Agreement to become
a Guarantor under the Guaranty in order to induce the Lenders to make additional
Loans and the Issuing Bank to issue additional Letters of Credit and as
consideration for Loans previously made and Letters of Credit previously issued.

            Accordingly, the Administrative Agent and the New Guarantor agree as
follows:

            SECTION 1. In accordance with Section 18 of the Guaranty, the New
Guarantor by its signature below becomes a Guarantor under the Guaranty with the
same force and effect as if originally named therein as a Guarantor and the New
Guarantor hereby (a) agrees to all the terms and provisions of the Guaranty
applicable to it as Guarantor thereunder and (b) represents and warrants that
the representations and warranties made by it as a Guarantor thereunder are true
and correct on and as of the date hereof. Each reference to a Guarantor in the
Guaranty shall be deemed to include the New Guarantor. The Guaranty is hereby
incorporated herein by reference.

            SECTION 2. The New Guarantor represents and warrants to the
Administrative Agent and the Lenders that (a) this Supplement has been duly
authorized, executed and delivered by it and constitutes its legal, valid and
binding obligation, enforceable against it in accordance with its

                                     E-1-1
<PAGE>

terms and (b) each of the representations and warranties set forth in Article IV
of the Credit Agreement that are applicable to a Subsidiary are true and correct
as of the date hereof as to such New Guarantor.

            SECTION 3. This Supplement may be executed in counterparts each of
which shall constitute an original, but all of which when taken together shall
constitute a single agreement. This Supplement shall become effective when the
Administrative Agent shall have received (a) counterparts of this Supplement
that, when taken together, bear the signatures of the New Guarantor and the
Administrative Agent and (b) the documents and opinion required by Section 5.10
of the Credit Agreement. Delivery of an executed signature page to this
Supplement by facsimile transmission shall be as effective as delivery of a
manually signed counterpart of this Supplement.

            SECTION 4. Except as expressly supplemented hereby, the Guaranty
shall remain in full force and effect.

            SECTION 5. THIS SUPPLEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF GEORGIA.

            SECTION 6. In case any one or more of the provisions contained in
this Supplement should be held invalid, illegal or unenforceable in any respect,
the validity, legality and enforceability of the remaining provisions contained
herein and in the Guaranty shall not in any way be affected or impaired thereby
(it being understood that the invalidity of a particular provision hereof in a
particular jurisdiction shall not in and of itself affect the validity of such
provision in any other jurisdiction). The parties hereto shall endeavor in
good-faith negotiations to replace the invalid, illegal or unenforceable
provisions with valid provisions the economic effect of which comes as close as
possible to that of the invalid, illegal or unenforceable provisions.

            SECTION 7. All communications and notices hereunder shall be in
writing and given as provided in Section 12 of the Guaranty. All communications
and notices hereunder to the New Guarantor shall be given to it at the address
set forth under its signature below, with a copy to the Borrower.

            SECTION 8. The New Guarantor agrees to reimburse the Administrative
Agent for its out-of-pocket expenses in connection with this Supplement,
including the reasonable fees, disbursements and other charges of counsel for
the Administrative Agent.

                                     E-1-2

            IN WITNESS WHEREOF, the New Guarantor and the Administrative Agent
have duly executed this Supplement to the Subsidiary Guaranty Agreement as of
the day and year first above written.
