such other address as may be designated by Tenet in writing. In the event the
date specified for any payment hereunder is not a Business Day, such payment
shall be made on the next following Business Day and Interest shall be paid at
the rate provided for herein on any such payment to the Business Day on which
such payment is made.

     (d) Duty to Pay Absolute. The duty of Guarantors to make any and all
         --------------------
payments in the manner specified hereunder shall be joint and several,
unconditional, irrevocable and absolute, and all such payments shall be made

     to which the Obligations were incurred, this Agreement, or any other
     document, instrument or agreement relating thereto or hereto (including,
     without limitation, any Assumption Agreements or any guarantees with

                                      -2-

     respect to the Obligations) (sometimes hereinafter being referred to
     collectively and severally as the "Related Documents");

          (ii) Any change in the time, manner or place of payment of, or any
     other term of, any or all of the Obligations;

          (iii) Any release, amendment or waiver of, or any consent to or
     departure from, any or all provisions of the Related Documents;

          (iv) The existence of any claim, set-off, defense or other right
     (including, but not limited to, right of contribution or similar right, if
     any) which Guarantors may have at any time against Tenet, each other or any
     other Person, whether in connection with a Related Document, a transaction
     contemplated by a Related Document or any other transaction; and

          (v) Any other circumstance which might otherwise constitute a defense
     available to, or a discharge of, Guarantors, any Subsidiary or Tenet.

Guarantors hereby waive, to the fullest extent permitted by law, any right to
proceed or make a claim against Tenet arising out of Tenet's payment of any
amount, whether or not any of the foregoing circumstances shall exist at any
time.

     2. Notice of Certain Payment Defaults. Prepayments or Terminations of
        ------------------------------------------------------------------

Obligation or prepays any Obligation, whether in whole or in part, or if any of
the Assumed Leases terminates, Guarantors shall give Tenet notice of such
payment default, prepayment or termination on the same day as the occurrence of
such payment default, prepayment or termination by telephonic notice confirmed
on the same day in writing or by telex or telecopy. Any confirmation in writing
provided pursuant to this Section 2 shall be provided in accordance with Section
7(b).

     3. Affirmative Covenants.
