          conditions of this Agreement and so long as no Default or Event of
          Default has occurred and is continuing, during the Revolving
          Credit Period, Lender agrees to issue irrevocable commercial
          and/or standby letters of credit for the account of Borrower
          and/or any Subsidiary (individually, a "Letter of Credit", and
          collectively, "Letters of Credit") in an amount and for the term
          specifically requested by Borrower by notice in writing to Lender
          at least three (3) Business Days prior to the requested issuance
          thereof; provided, however, that: (i) Borrower shall have executed
          and delivered to Lender a Letter of Credit Application with
          respect to such Letter of Credit; (ii) the term of any such Letter
          of Credit shall not extend beyond the earlier of (A) the date one
          (1) year after the date of issuance thereof, or (B) the last day
          of the Revolving Credit Period; (iii) any Letter of Credit may

          unreimbursed drawings with respect thereto shall not as of any
          date exceed Five Million Dollars ($5,000,000.00); and (vi) the
          text of any such Letter of Credit is provided to Lender no less
          than three (3) Business Days prior to the


                                   - 2 -




          requested issuance date, which text must be acceptable to Lender
          in its sole and absolute discretion.

               (b) The payment of drafts under each Letter of Credit shall
          be made in accordance with the terms thereof and, in that
          connection, Lender shall be entitled to honor any drafts and
          accept any documents presented to it by the beneficiary of such
          Letter of Credit in accordance with the terms of such Letter of
          Credit and the related Letter of Credit Application and believed
          in good faith by Lender to be genuine. Lender shall not have any
          duty to inquire as to the accuracy or authenticity of any draft or
          other drawing document that may be presented to it other than the
          duties contemplated by the applicable Letter of Credit
          Application.

               (c) In the event of any payment by Lender of a draft
          presented under a Letter of Credit, Borrower agrees to pay to
          Lender in immediately available funds at the time of such drawing
          an amount equal to the sum of such drawing plus the negotiation,
                                                     ----
          processing and other fees related thereto, as may be agreed
          between Lender and Borrower from time to time (the initial fee
          schedule is attached to the First Amendment to Revolving Credit
          Agreement dated as of April __, 2003, as Exhibit A thereto).
          Borrower hereby authorizes Lender to charge or cause to be charged
          one or more of Borrower's deposit accounts at Lender to the extent
          there are balances of immediately available funds therein, in an
          aggregate amount equal to the sum of such drawing plus the
                                                            ----
          negotiation, processing and other fees related thereto as
          described in Exhibit A to the First Amendment to Revolving Credit
          Agreement dated as of April __, 2003, as amended, and Borrower
          agrees to pay the amount of any such drawing (and/or Lender's
          customary negotiation, processing and other fees related thereto)
          not so charged prior to the close of business of Lender on the day
          of such drawing. In the event any payment under a Letter of Credit
          is made by Lender prior to receipt of payment from Borrower, such
          payment by Lender shall constitute a request by Borrower for a
          Prime Loan under Sections 2.01 and 2.02 above (and Lender will
          make such Prime Loan to Borrower regardless of whether any Default
          or Event of Default under this Agreement has occurred and is
          continuing and regardless of whether such Prime Loan would
          otherwise be permitted under the requirements of this Agreement)
          and the proceeds of such Prime Loan shall be paid directly to
          Lender and applied by Lender to the payment of any amounts owed by
          Borrower to Lender under this Section 2.18.

               (d) Borrower hereby further agrees to pay to the order of
          Lender with respect to each Letter of Credit: (i) a nonrefundable
          commitment fee at an annual rate of 725/1000 Percent (.725%)
          (calculated on an actual day, 360-day year basis) on the face
          amount (taking into account any scheduled increases or decreases
          therein during the period in question) of each Letter of Credit,
          due and payable quarterly, in arrears, on the first day of each
          fiscal quarter; and (ii) a nonrefundable issuance fee, a
          nonrefundable negotiation fee and such other fees as may be
          charged by Lender from time to time in accordance with Lender's
          published schedule of fees in effect from time to time, which fees
          shall be due and payable on demand by Lender.

               (e) Notwithstanding any provision contained in this Agreement
          to the contrary, if any Letters of Credit remain outstanding on
          the last day of the Revolving Credit Period, Borrower shall, on or
          before 12:00 noon (St. Louis time) on the last day of the Revolving
          Credit Period, (i) surrender the originals of the applicable
          Letter(s) of Credit to Lender for cancellation, or (ii) provide
          Lender with cash collateral (or other collateral acceptable to
          Lender in its sole and absolute discretion) in an amount at least
          equal to the aggregate undrawn face amount of all outstanding
          Letter(s) of Credit plus all unreimbursed drawings with respect
                              ----
          thereto, and execute and deliver to


                                   - 3 -





          Lender such agreements as Lender may require to grant Lender a
          first priority perfected security interest in such cash or other
          collateral. Any such cash collateral received by Lender pursuant
          to this Section 2.18(e) shall be held by Lender in a separate
          account at Lender appropriately designated as a cash collateral
          account in relation to this Agreement and the Letters of Credit
          and retained by Lender as collateral security for the payment of
          Borrower's Obligations. Cash amounts delivered to Lender pursuant
          to the foregoing requirements of this Section 2.18(e) shall be
          invested, at the request and for the account of Borrower in
          investments of a type and nature and with a term acceptable to
          Lender. Such amounts, including in the case of cash amounts
          invested in the manner set forth above, shall not be used by
          Lender to pay any amounts drawn or paid under or pursuant to any
          Letter of Credit, but may be applied to reimburse Lender for
          drawings or payments under or pursuant to such Letters of Credit
          which Lender has paid, or if no such reimbursement is required to
          the payment of such of the other Borrower's Obligations as Lender
          shall determine. Any amounts remaining in any cash collateral
          account established pursuant to this Section 2.18(e) after the
          payment in full of all of the Borrower's Obligations and the
          expiration or cancellation of all of the Letters of Credit shall
          be returned to Borrower (after deduction of Lender's reasonable
          expenses, if any)."

     (e) Section 5.01(f) of the Agreement is deleted and substituted with
     the following:

               "(f) Maximum Consolidated Capitalization Ratio. LGC will at
                    -----------------------------------------
