      M. except for those guaranties and obligations existing as of the date
      hereof and disclosed on the attached Schedule 9.M, or otherwise in the
      ordinary course of Borrower's business, the Borrower shall not assume,
      guarantee, endorse, contingently agree to purchase or otherwise become
      liable (directly or indirectly, absolutely or contingently) in connection
      with the obligations of any other person, firm or corporation, nor shall
      the Borrower make or permit to exist any loans or advances by the Borrower
      to, or purchase or otherwise acquire all or any substantial part of the
      assets of, or any shares of stock or similar interest in, any other
      person, corporation or entity; provided, however, loans or advances by and
      between the Borrower and the Guarantor shall be permitted and shall not
      require advance consent of the Lender;

      N. not to undertake or permit without prior written approval of the Lender
      any other or additional construction on the Project site that is the

      P. Borrower shall not permit, as at the end of each fiscal quarter, the
      Debt Service Coverage Ratio to be less than 1.25 to 1.00. For purposes of
      this provision "Debt Service Coverage Ratio" means, as at the end of any
      fiscal quarter for the three month fiscal quarter ending on such date
      (i.e. the last day of September, December, March and June) for Borrower,
      the ratio whose numerator is EBITDA, minus non-financed capital
      expenditures, minus cash taxes, and whose denominator is interest
      payments, plus the current maturities of long-term debt, plus the current
      portion of capital leases. "EBITDA" means, in any fiscal period,
      Borrower's net income for net loss (other than extraordinary or
      non-recurring gains of Borrower for such period), plus (i) the amount of
      all interest expense, income tax expense, depreciation expense and
      amortization expense of Borrower for such period, and plus or minis (as
      the case may be) (ii) any other non-cash charges which have been added or
      subtracted, as the case may be, in calculating Borrower's net income for
      such period.

9.    Event of Default Defined. As used herein, the term "Event of Default"
      shall mean and include each or all of the following events:

      A. the Borrower or Guarantor shall fail to pay, when due, any amounts
      required to be paid by the Borrower under the Note, or any other
      indebtedness of the Borrower or Guarantor to the Lender, or the Borrower
      or the Guarantor shall otherwise be in default under the terms of any or

      within the applicable cure period or the third party lender has not
      otherwise waived the default;

      B. the Borrower or Guarantor shall fail to observe or perform any of their
      respective covenants, conditions or agreements to be observed or performed
      by either of them under the Borrower Documents, the Guaranty or any other

      Guaranty for a period of five (5) days after written notice, specifying
      such default and requesting that it be remedied, given to such party by
      the Lender, unless the Lender shall agree in writing to an extension of
      such time prior to its expiration, or for such longer period as may be
      reasonably necessary to remedy such default (other than defaults which can
      be cured by a money payment) provided that such party is proceeding with
      reasonable diligence to remedy the same;

      C. the Borrower or Guarantor shall file a petition in bankruptcy or for
      reorganization or for an arrangement pursuant to any present or future
      state or federal bankruptcy act or under any similar federal or state law,

      assignment for the benefit of its or his creditors, or shall be unable to
      pay its debts generally as they become due; or if a petition or answer
      proposing the adjudication of the Borrower or Guarantor as a bankrupt or
      its reorganization under any present or future state or federal bankruptcy
      act or any similar federal or state law shall be filed in any court and
      such petition or answer shall not be discharged or denied within
      forty-five (45) days after the filing thereof; or if a receiver, trustee
      or liquidator of the Borrower or any Guarantor or of all or substantially
      all of the assets of the Borrower or


                                      -9-

      certificate or report furnished hereunder or under any of the foregoing
      documents by or on behalf of the Borrower or Guarantor shall prove to be
      untrue or misleading in any material respect on the date when the facts
      set forth and recited therein are stated or certified;

      G. any material adverse change in the financial condition of the Borrower
      or Guarantor which, in the reasonable opinion of the Lender, increases its
      risk with respect to the Note;

      H. the Borrower or Guarantor shall liquidate, dissolve, terminate or
      suspend its business operations or otherwise fail to operate its business
      in the ordinary course, or sell all or substantially all of its assets,
      without the prior written consent of the Lender;

      I. except as otherwise provided in the Mortgage, the Borrower or the
      Guarantor shall fail to pay, withhold, collect or omit any tax or tax
      deficiency when assessed or due (other than any tax or tax deficiency
      which is being contested in good faith and by proper proceedings and for
      which it shall have set aside on its books adequate reserves therefor) or
      notice of any state or federal tax liens shall be filed or issued;
