                                JOINDER AGREEMENT

                  THIS JOINDER AGREEMENT (the "Agreement"), dated as of April
30, 2003, is by and between JORDAN VALLEY HOSPITAL, LP, a Delaware limited
partnership (the "New Subsidiary"), and BANK OF AMERICA, N. A., in its
capacities as Administrative Agent and Collateral Agent under that certain
Amended and Restated Credit Agreement (as it may be amended, modified, restated
or supplemented from time to time, the "Credit Agreement"), dated as of February
7, 2003, by and among IASIS Healthcare Corporation, a Delaware corporation (the
"Borrower"), the Guarantors party thereto, the Lenders party thereto and Bank of
America, N. A., as Administrative Agent. All of the defined terms in the Credit
Agreement are incorporated herein by reference.

                  The Credit Parties are required by Section 9.11 of the Credit
Agreement to cause the New Subsidiary to become a "Guarantor".

                  Accordingly, the New Subsidiary hereby agrees as follows with
the Administrative Agent, for the benefit of the Lenders:

                  1.       The New Subsidiary hereby acknowledges, agrees and
confirms that, by its execution of this Agreement, the New Subsidiary will be
deemed to be a party to the Credit Agreement and a "Guarantor" for all purposes
of the Credit Agreement, and shall have all of the rights and obligations of a
Guarantor thereunder as if it had executed the Credit Agreement. The New
Subsidiary hereby ratifies, as of the date hereof, and agrees to be bound by,
all of the terms, provisions and conditions applicable to the Guarantors
contained in the Credit Agreement. Without limiting the generality of the
foregoing terms of this paragraph 1, the New Subsidiary hereby jointly and
severally, together with the other Guarantors, guarantees to each Lender and the
Administrative Agent, as provided in Section 5 of the Credit Agreement, the
prompt payment of the Obligations in full when due (whether at stated maturity,
as a mandatory prepayment, by acceleration or otherwise, giving effect to any
grace periods) strictly in accordance with the terms thereof.

                  2.       The New Subsidiary hereby acknowledges, agrees and
confirms that, by its execution of this Agreement, the New Subsidiary will be
deemed to be a party to the Security Agreement, and shall have all the rights
and obligations of an "Assignor" (as such term is defined in the Security
Agreement) thereunder as if it had executed the Security Agreement. The New
Subsidiary hereby ratifies, as of the date hereof, and agrees to be bound by,
all of the terms, provisions and conditions applicable to the "Assignor"
contained in the Security Agreement. Without limiting the generality of the
foregoing terms of this paragraph 2, to secure the prompt payment and
performance in full when due, whether by lapse of time, acceleration, mandatory
prepayment or otherwise of the Obligations (as defined in the Security
Agreement) the New Subsidiary hereby confirms and grants to the Administrative
Agent, for the ratable benefit of the Lenders, a continuing security interest in
any and all right, title and interest of the New Subsidiary in and to the
Collateral (as such term is defined in Section 1.1(c) of the Security Agreement)
of the New Subsidiary. The New Subsidiary hereby represents and warrants to the
Administrative Agent as of the date hereof that the information set forth on
each the Schedules attached to this Joinder Agreement is true and complete as of
the date hereof.

                  3.       The New Subsidiary hereby acknowledges, agrees and
confirms that, by its execution of this Agreement, the New Subsidiary will be
deemed to be a party to the Pledge Agreement, and shall have all the rights and
obligations of a "Pledgor" thereunder as if it had executed the Pledge
Agreement. The New Subsidiary hereby ratifies, as of the date hereof, and agrees
to be bound by, all the terms, provisions and conditions applicable to the
"Pledgor" contained in the Pledge Agreement. Without limiting the generality of
the foregoing terms of this paragraph 3, to secure the prompt payment and

performance in full when due, whether by lapse of time, acceleration, mandatory
prepayment or otherwise, of the Obligations (as defined in the Pledge
Agreement), the New Subsidiary hereby confirms and pledges and assigns to the
Collateral Agent, for the ratable benefit of the Lenders, and confirms and
grants to the Collateral Agent, for the ratable benefit of the Lenders, a
continuing security interest in any and all right, title and interest of the New
Subsidiary in and to the Collateral (as such term is defined in Section 3.1 of
the Pledge Agreement) listed on Schedules 10, 11, 12 and 13 attached hereto.

                  4.       Unless otherwise notified to the Administrative Agent
in accordance with Section 14.03 of the Credit Agreement, the address of the New
Subsidiary for purposes of all notices and other communications is the address
set forth on Schedule 1 hereto.

                  5.       The New Subsidiary hereby waives acceptance by the
Administrative Agent, the Collateral Agent and the Lenders of the guaranty by
the New Subsidiary under Section 5 of the Credit Agreement upon the execution of
this Agreement by the New Subsidiary.

                  6.       This Agreement may be executed in two or more
counterparts, each of which shall constitute an original but all of which when
taken together shall constitute one contract.

                  7.       THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

                  8.       The information set forth in Schedules 1 through 8
hereto shall be deemed to supplement the applicable schedules to the Security
Agreement. The information set forth in Schedules 3 and 9 through 13 hereto
shall be deemed to supplement the applicable schedules to the Pledge Agreement.
The information set forth in Schedule 14 hereto shall be deemed to supplement
Schedule 8.13 to the Credit Agreement.

                                JOINDER AGREEMENT

                  THIS JOINDER AGREEMENT (the "Agreement"), dated as of August
1, 2003, is by and between Southeast Texas Hospital, LP, a Delaware limited
partnership (the "New Subsidiary"), and BANK OF AMERICA, N. A., in its
capacities as Administrative Agent and Collateral Agent under that certain
Amended and Restated Credit Agreement, dated as of February 7, 2003, as amended
(as it may be amended, modified, restated or supplemented from time to time, the
"Credit Agreement"), by and among IASIS Healthcare Corporation, a Delaware
corporation (the "Borrower"), the Guarantors party thereto, the Lenders party
thereto and Bank of America, N. A., as Administrative Agent. All of the defined
terms in the Credit Agreement are incorporated herein by reference.

                  The Credit Parties are required by Section 9.11 of the Credit
Agreement to cause the New Subsidiary to become a "Guarantor".

                  Accordingly, the New Subsidiary hereby agrees as follows with
the Administrative Agent, for the benefit of the Lenders:

                  1.       The New Subsidiary hereby acknowledges, agrees and
confirms that, by its execution of this Agreement, the New Subsidiary will be
deemed to be a party to the Credit Agreement and a "Guarantor" for all purposes
of the Credit Agreement, and shall have all of the rights and obligations of a
Guarantor thereunder as if it had executed the Credit Agreement. The New
Subsidiary hereby ratifies, as of the date hereof, and agrees to be bound by,
all of the terms, provisions and conditions applicable to the Guarantors
contained in the Credit Agreement. Without limiting the generality of the
foregoing terms of this paragraph 1, the New Subsidiary hereby jointly and
severally, together with the other Guarantors, guarantees to each Lender and the
Administrative Agent, as provided in Section 5 of the Credit Agreement, the
prompt payment of the Obligations in full when due (whether at stated maturity,
as a mandatory prepayment, by acceleration or otherwise, giving effect to any
grace periods) strictly in accordance with the terms thereof.

                  2.       The New Subsidiary hereby acknowledges, agrees and
confirms that, by its execution of this Agreement, the New Subsidiary will be
deemed to be a party to the Security Agreement, and shall have all the rights
and obligations of an "Assignor" (as such term is defined in the Security
Agreement) thereunder as if it had executed the Security Agreement. The New
Subsidiary hereby ratifies, as of the date hereof, and agrees to be bound by,
all of the terms, provisions and conditions applicable to the "Assignor"
contained in the Security Agreement. Without limiting the generality of the
foregoing terms of this paragraph 2, to secure the prompt payment and
performance in full when due, whether by lapse of time, acceleration, mandatory
prepayment or otherwise of the Obligations (as defined in the Security
Agreement) the New Subsidiary hereby confirms and grants to the Administrative
Agent, for the ratable benefit of the Lenders, a continuing security interest in
any and all right, title and interest of the New Subsidiary in and to the
Collateral (as such term is defined in Section 1.1(c) of the Security Agreement)
of the New Subsidiary. The New Subsidiary hereby represents and warrants to the
Administrative Agent as of the date hereof that the information set forth on
each the Schedules attached to this Joinder Agreement is true and complete as of
the date hereof.

                  3.       The New Subsidiary hereby acknowledges, agrees and
confirms that, by its execution of this Agreement, the New Subsidiary will be
deemed to be a party to the Pledge Agreement, and shall have all the rights and
obligations of a "Pledgor" thereunder as if it had executed the Pledge
Agreement. The New Subsidiary hereby ratifies, as of the date hereof, and agrees
to be bound by, all the terms, provisions and conditions applicable to the
"Pledgor" contained in the Pledge Agreement. Without limiting the generality of
the foregoing terms of this paragraph 3, to secure the prompt payment and

performance in full when due, whether by lapse of time, acceleration, mandatory
prepayment or otherwise, of the Obligations (as defined in the Pledge
Agreement), the New Subsidiary hereby confirms and pledges and assigns to the
Collateral Agent, for the ratable benefit of the Lenders, and confirms and
grants to the Collateral Agent, for the ratable benefit of the Lenders, a
continuing security interest in any and all right, title and interest of the New
Subsidiary in and to the Collateral (as such term is defined in Section 3.1 of
the Pledge Agreement) listed on Schedules 10, 11, 12 and 13 attached hereto.

                  4.       Unless otherwise notified to the Administrative Agent
in accordance with Section 14.03 of the Credit Agreement, the address of the New
Subsidiary for purposes of all notices and other communications is the address
set forth on Schedule 1 hereto.

                  5.       The New Subsidiary hereby waives acceptance by the
Administrative Agent, the Collateral Agent and the Lenders of the guaranty by
the New Subsidiary under Section 5 of the Credit Agreement upon the execution of
this Agreement by the New Subsidiary.

                  6.       This Agreement may be executed in two or more
counterparts, each of which shall constitute an original but all of which when
taken together shall constitute one contract.

                  7.       THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

                  8.       The information set forth in Schedules 1 through 8
hereto shall be deemed to supplement the applicable schedules to the Security
Agreement. The information set forth in Schedules 3 and 9 through 13 hereto
shall be deemed to supplement the applicable schedules to the Pledge Agreement.
