                           (z) if requested by the applicable Lender, Notes with
                  respect to such added Revolving Credit Commitments shall have
                  been executed and delivered by the Company.

                  (ii) Upon receipt of the notice referred to in clause (i)(x)
         above, the Agent shall promptly notify each Lender thereof. Upon
         execution and delivery of the documents referred to in clause (i)
         hereof, such new Lender shall constitute a "Lender" hereunder with a
         Revolving Credit Commitment as specified therein. Immediately upon the
         effectiveness of the addition of such new Lender under this Section
         2.03(e) all the Revolving Credit Commitments shall, on the terms and
         conditions hereof, be deemed to be reborrowed pro rata among all of the
         Lenders (including the new Lenders) based on their Revolving Credit
         Commitments as then in effect and the Agent will net out the
         differences based on each Lender's pro rata share of the Revolving
         Credit Commitments before and after giving effect to the increase in
         the aggregate amount of the Revolving Credit Commitments. Each new
         Lender (A) shall be deemed to have assumed such portion of such
         Revolving Credit Loans and (B) shall fund to each other Lender on the
         day of the increase in the Revolving Credit Commitments all Revolving
         Credit Loans assigned to it by each such other Lender, as specified by
         the Agent. The Company agrees to pay to the Lenders on demand any and
         all amounts to the extent payable pursuant to Section 5.05 of the
         Credit Agreement as a result of any such prepayment of the Revolving
         Credit Loans occasioned by the foregoing increase in the Revolving
         Credit Commitments."
