                           shall have occurred and be continuing on the date
                           when such change would otherwise occur, it being

                           amount of such Century Letter of Credit, for purposes
                           of this Agreement, provided, however, that if any
                           Century Letter of Credit expires or is canceled
                           without a drawing occurring thereunder, then the
                           amount of the Capital Expenditure related to such
                           Century Letter of Credit shall be deemed to have been

                           accepted by the Borrowers from the other lender(s)
                           were the same as or more favorable to the Borrowers
                           than those requested by the Borrowers in clause (i)
                           above."

         (bb)     The first sentence of Section 4.5 of the Loan Agreement is

         inure to the sole benefit of, the Borrowers, the Agent and the Lenders,
         and their respective successors and assigns.

11.      Continued Effectiveness. Notwithstanding anything contained herein, the
         terms of this Amendment are not intended to and do not serve to effect
         a novation as to the Loan Agreement; instead, it is the express
         intention of the parties hereto to reaffirm the Obligations created
         under the Loan Agreement which are secured by the Collateral. The Loan
         Agreement, as amended hereby, and each of the other Loan Documents
         shall remain in full force and effect.

12.      Costs, Expenses and Indemnity. The Borrowers affirm and acknowledge

executed and delivered by the Guarantor in connection with the Guaranty, and
agrees that such obligations of the Guarantor would not be limited or diminished
in any manner even if the Guarantor had not executed this Amendment, (iii)
agrees that this Amendment shall not be construed as requiring the consent of
the Guarantor in any other circumstance, (iv) reaffirms its obligations under
the Guaranty and such other related documents, and (v) agrees that the Guaranty
and such other related documents remain in full force and effect and are hereby
ratified and confirmed. Without limiting the generality of the foregoing, the
Guarantor agrees to perform and comply with each of the covenants contained in
sections 9.9 through 9.28 of the Loan Agreement, as amended by this Amendment,
which by their terms refer to the Guarantor, and further agrees not to cause or
permit either Borrower to violate any of such covenants.

         The Guarantor further agrees that all terms, conditions and provisions
of the Loan Agreement relating to Letters of Credit (as defined in the Loan
Agreement) shall be deemed to apply to the Century Letters of Credit (as defined
in this Amendment), and that all agreements of the Borrowers contained in the
Loan Agreement with respect to the Letters of Credit shall be deemed to be
agreements of the Guarantor with respect to the Century Letters of Credit. In
furtherance and not in limitation of the foregoing:

         (1)      The Guarantor hereby specifically agrees to protect,
                  indemnify, pay and save the Lenders and the Agent harmless
                  from and against any and all claims, demands, liabilities,
                  damages, losses, costs, charges and expenses (including
                  reasonable attorneys' fees) which any Lender or the Agent may
                  incur or be subject to as a consequence, direct or indirect,
                  of the issuance of any Century Letter of Credit or the
                  provision of any credit support or enhancement in connection
                  therewith.

         (2)      As among the Guarantor, the Lenders, and the Agent, the
                  Guarantor, subject to paragraphs (3) and (4) below, assumes
                  all risks of the acts and omissions of, or misuse of any of
                  the Century Letters of Credit by, the respective beneficiaries
                  of such Century Letters of Credit. In furtherance and not in
                  limitation of the foregoing, subject to the provisions of the
                  application for the issuance of the Century Letters of Credit,
                  the Lenders and the Agent shall not be responsible for: (A)
                  the form, validity, sufficiency, accuracy, genuineness or
                  legal effect of any document submitted by any Person in
                  connection with the application for and issuance of and
                  presentation of drafts with respect to any of the Century
                  Letters of Credit, even if it should prove to be in any or all
                  respects invalid, insufficient, inaccurate, fraudulent or
                  forged; (B) the validity or sufficiency of any instrument
                  transferring or assigning or purporting to transfer or assign
                  any Century Letter of Credit or the rights or benefits
                  thereunder or proceeds thereof, in whole or in part, 

                                       40
   24
                  which may prove to be invalid or ineffective for any reason;
                  (C) the failure of the beneficiary of any Century Letter of
                  Credit to comply duly with conditions required in order to
                  draw upon such Century Letter of Credit; (D) errors,
                  omissions, interruptions, or delays in transmission or
                  delivery of any messages, by mail, cable, telegraph, telex or
                  otherwise, whether or not they be in cipher; (E) errors in
                  interpretation of technical terms; (F) any loss or delay in
                  the transmission or otherwise of any document required in
                  order make a drawing under any Century Letter of Credit or of
                  the proceeds thereof; (G) the misapplication by the
                  beneficiary of any Century Letter of Credit of the proceeds of
                  any drawing under such Century Letter of Credit; or (H) any
                  consequences arising from causes beyond the control of the
                  Lenders or the Agent, including, without limitation, any act
                  or omission, whether rightful or wrongful, of any present or
                  future de jure or de facto Governmental Authority. None of the
                  foregoing shall affect, impair or prevent the vesting of any
                  rights or powers of the Agent or any Lender under this
                  Consent.

         (3)      In furtherance and extension, and not in limitation, of the
                  specific provisions set forth above, any action taken or
                  omitted by the Agent or any Lender under or in connection with
                  any of the Century Letters of Credit or any related
                  certificates, if taken or omitted in the absence of gross
                  negligence or willful misconduct, shall not put the Agent or
                  any Lender under any resulting liability to either Borrower or
                  the Guarantor or relieve each Borrower or the Guarantor of any
                  of its obligations under the Loan Agreement or hereunder to
                  any such Person.

         (4)      Nothing contained in this Consent shall be deemed to govern
                  the relation of the Guarantor and the issuer of any Century
                  Letter of Credit; it being understood that the Guarantor may
                  be requested to execute and deliver to the issuer of any
                  Century Letter of Credit such documents and agreements as such
                  issuer may require to issue such Century Letter of Credit.
