                      CURRENT INFORMATION CONCERNING THE PLAN

1. Board of Directors: 

  As of January 31, 1994, the Board of Directors was comprised of Messrs.
Frederick R. Adler, Ferdinand Colloredo-Mansfeld, John G. McElwee, Ronald L.

Number of Shares                  Share Option               Range of
Subject to Option               Exercise Price             Expiration Dates

  8,000                              $7.44                 1/28/96 - 5/2/99

owned an aggregate of 361,012 shares of Common Stock as of December 31, 1993.

6.Tax Consequences:

  An option granted under the Plan is a nonstatutory option and is taxed in
accordance with Section 83 of the Internal Revenue Code of 1986 and regulations
thereunder.  A non-employee director granted an option under the Plan generally
will realize income when the shares purchased pursuant to the option become
transferable or are no longer subject to a substantial risk of forfeiture.  The
income realized (the difference between the exercise price of the option and the
fair market value of the shares at the time the shares are transferable or are
no longer subject to a substantial risk of forfeiture) will be ordinary income
to the non-employee director.  Currently, the maximum individual tax rate for
ordinary income is 39.6% and for capital gain is 28%.


                  SECURITIES AND EXCHANGE COMMISSION POSITION ON
                  INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

  Section 145 of the General Corporation Law of Delaware permits indemnification
of directors, officers and employees of a corporation under certain conditions
and subject to certain limitations.  Article VI of the Company's By-Laws
contains provisions for the indemnification of directors, officers and employees
of the Company within the limitations permitted by Section 145.

  The Company carries a directors' and officers' liability insurance policy
which provides for payment of expenses of the Company's directors and officers
in connection with threatened, pending or completed actions, suits or
proceedings against them in their capacities as directors and officers, in
accordance with the Company's By-Laws and the General Corporation Law of
Delaware.

  Insofar as indemnification for liabilities arising under the Securities Act of
1933, as amended (the "33 Act"), may be permitted to directors, officers, or
persons controlling the Company pursuant to the foregoing provisions, the
Company has been informed that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the '33
Act and is therefore unenforceable.
