                                    RECITALS

       WHEREAS, the Company has requested that the Credit Agreement be amended

Credit Agreement shall mean the Credit Agreement as hereby amended.

       2.     Amendments to Credit Agreement.

              2.1    Add a new Section 2.1(a) as follows:

              Section 2.1 (a) Additional Banks. (a) On the effective date (when
all conditions precedent set forth in Section 4 hereof have been met) each
Additional Bank and each Existing Bank shall purchase or sell, as the case may

its share of the Aggregate Commitment indicated on Schedule 1.1 hereto.

              2.2    Schedules 1.1 and 3 attached to the Credit Agreement shall
be deleted and Schedule 1.1 and 3 attached to this Second Amendment shall be
inserted in lieu thereof.

              2.3    The definition of "Maturity Date" in Section 1.1 of the
Credit Agreement is hereby amended by deleting "August 17, 1995" and inserting

follows:

              "Offshore Applicable Margin" means, with respect to Offshore Rate
              Loans, 0.225% per annum."

              2.5    Section 2.10(b) shall be amended by substituting the words
"facility fee" for the words "commitment fee" wherever they appear in this
Section and by amending and restating the first sentence thereof in its
entirety as follows:

              "The Company shall pay to the Agent a facility fee on the
Aggregate Commitment, computed on a quarterly basis in arrears on the last

distributed to each Bank in accordance with its Pro Rata Share."
