         2. Representations, Warranties, Covenants and Acknowledgments; Release.
To induce the Lender to enter into this Agreement:

                  (a) Borrower does hereby represent and warrant that (i) as of
the date hereof, all of the representations and warranties made or deemed to be
made under the Loan Documents are true and correct, except such representations
and warranties which, by their express terms, are applicable only to the Closing
Date, (ii) as of the date hereof, after giving effect to the terms hereof and
other than as contemplated by that certain waiver letter, dated of even date

legal, valid and binding obligation of the Borrower enforceable against it in
accordance with its terms: and

                  (b) Borrower does hereby reaffirm each of the agreements,
covenants, and undertakings set forth in the Loan Agreement and each and every
other Loan Document executed in connection therewith or pursuant thereto as if
Borrower were making said agreements, covenants and undertakings on the date

                  (c) Borrower does hereby acknowledge and agree that no right

Obligations, this Agreement, the Loan Agreement or any of the other Loan
Documents, (ii) any other documents now or heretofore evidencing, securing or in

                  (d) Borrower does hereby expressly waive, release and
relinquish any and all defenses, setoffs, counterclaims, causes of action or
objections, if any, against Lender.

                  (a) Delivery of Documents. Borrower shall have delivered to
Lender, all in form and substance acceptable to Lender in its sole discretion,
executed counterpart originals of this Agreement;

                  (b) Accuracy of Representations and Warranties. All of the
representations and warranties made or deemed to be made in this Agreement and
under the Loan Documents

                                       2


shall be true and correct as of the date of this Agreement, except such
representations and warranties which, by their terms, are applicable to a prior
specific date or period; and

expenses referred to in Section 5 hereof.

         4. Effect of this Agreement. As expressly amended hereby, the Loan

expenses of Lender in connection with the preparation, execution, delivery and

transactions contemplated hereby, including, without limitation, the reasonable
fees and out-of-pocket expenses of legal counsel to Lender. Borrower authorizes
Lender, as Agent, to charge the foregoing expenses to the Borrower's loan
account by increasing the principal amount of the Revolving Credit Loans by the
amount of such expenses owed by Borrower in connection herewith.

         6. Miscellaneous. Borrower agrees to take such further action as Lender
shall reasonably request in connection herewith to evidence the amendments

and all of which counterparts, taken together, shall constitute but one and the
same instrument. This Agreement shall be binding upon and inure to the benefit
of the successors and permitted assigns of the parties hereto. This Agreement
shall be governed by, and construed in accordance with, the laws of the State of
Georgia.

                                    a) Upon and subject to the terms and
                  conditions of this Agreement, Lenders agree to make advances
                  (each a "Capex Advance"), from time to time, to Borrower
                  against Eligible Capital Expenditures in an aggregate amount
                  outstanding which shall not exceed the Capex Borrowing
                  Availability. Amounts repaid under the Capex Facility may not
                  thereafter be reborrowed. The Capex Facility shall be
                  evidenced by the Capex Note. The date and amount of each Capex
                  Advance and each payment of principal with respect thereto
                  shall be recorded on the books and records of Agent, which
                  books and records shall constitute evidence of the accuracy of
                  the information therein recorded.

                                    a) On or promptly after each Capex Advance
                  Request Date, Borrower shall furnish Agent with a request for
                  a Capex Advance (each, a "Capex Advance Request") which (A)
                  has attached thereto a Capex Certificate substantially in the
                  form of Exhibit A-3 hereto, completed and signed by the chief
                  executive officer or chief financial officer of Borrower, (B)
                  sets forth the amount of the proposed Capex Advance and
                  whether it is a Prime Rate Option Advance or a LIBOR Option
                  Advance, and (C) furnishes such other information as may be
                  requested by Agent. Each such Capital Advance Request shall be
                  given in writing, substantially in the form of Exhibit A-3
                  hereto, and shall be sent by Borrower via telecopy, hand
                  delivery or United States mail to Agent at General Electric
                  Capital Corporation, 3379 Peachtree Road, NE, Suite 600,
                  Atlanta, Georgia 30326, Attention: Senior Vice President - BTI
                  Portfolio (or such other person or address as Agent may
                  designate to Borrower in writing), Fax No. (404) 262-9175
                  within ten (10) days after the Capex Advance Request Date. The
                  proceeds of each Capex Advance shall be used by Borrower to
                  repay the Revolving Credit Loan to the extent such capital
                  expenditures have been paid from the proceeds of any Revolving
                  Credit Advances and, accordingly, Borrower irrevocably
                  authorizes and instructs Agent to apply the proceeds of such
                  amounts against the outstanding balance of the Revolving
                  Credit Loan and, the balance, if any, shall be placed in an
                  account designated by Borrower, which account shall be the
                  subject of the lien of Agent, for the benefit of Lenders. To
                  the extent that Borrower has not paid for such capital
                  expenditures out of the Revolving Credit


                                       11



                  Facility, Borrower shall furnish to Agent the information set
                  forth above in this paragraph (ii), each creditor's wire
                  transfer information and such other information as Agent may
                  request and Agent shall wire transfer the amounts payable to
                  such creditors from the proceeds of the Capex Advance and, the
                  balance, if any, shall be placed in an account designated by
                  Borrower, which account shall be the subject of the lien of
                  Agent, for the benefit of Lenders. Borrower agrees that in
                  making any Capex Advance hereunder, Agent shall be entitled to
                  rely upon and shall be fully protected under this Agreement in
                  relying upon any Capex Advance Request believed by Agent to be
                  genuine and in assuming that the persons executing and
                  delivering the same were duly authorized, unless the
                  responsible individual acting thereon for Agent shall have
                  actual knowledge to the contrary. Borrower hereby agrees that
                  Agent can require new appraisals related to Eligible Capital
                  Expenditures at any time or from time to time; provided,
                  however, that as long has no Default has occurred hereunder
                  (or an event that with notice or the passage of time or both
                  would constitute a Default hereunder), Agent hereby agrees
                  that such appraisals shall not be required any more frequently
                  than annually. Such appraisals shall be conducted by an
                  appraiser satisfactory to Agent, in its sole discretion, and
                  shall be in a form acceptable to Agent.

                                    a) The aggregate principal amount of the
                  Capex Note is due and payable on the Commitment Termination
                  Date; provided, that, in the event that the Capex Advances
                  outstanding at any time exceed the Maximum Capex Loan,
                  Borrower shall immediately pay to Lenders such excess amount.

                  (d) The Loan Agreement is hereby further amended by making the
         following changes thereto:

                  interest, fees and expenses thereon and (iv) the termination
                  of


                                       12
