         This Indemnification Agreement is made effective as of the 1st day of
December, 2003, between Ardent Health Services LLC, a Delaware limited
liability company (the "Company"), and R. Dirk Allison (the "Indemnitee").

                                  WITNESSETH:

         WHEREAS, it is essential to the Company and its stockholders to
attract and retain qualified and capable directors, officers, employees, agents
and fiduciaries; and

and officers so as to provide them with the maximum possible protection
permitted by law; and

         WHEREAS, in recognition of Indemnitee's need for protection against
personal liability in order to induce Indemnitee to serve or continue to serve
the Company in an effective manner, and, in the case of directors and officers,
to supplement the Company's directors' and officers' liability insurance
coverage, the Company wishes to provide the Indemnitee with the benefits
contemplated by this Agreement; and

         WHEREAS, as a result of the provision of such benefits Indemnitee has
agreed to serve or to continue to serve the Company;

         2.       Basic Indemnification Agreement. In consideration of, and as
an inducement to, the Indemnitee rendering valuable services to the Company,
the Company agrees that in the event Indemnitee is or becomes a party to or
witness or other participant in, or is threatened to be made a party to or
witness or other participant in, a Claim by reason of (or arising in part out
of) an Indemnifiable Event, the Company will advance Expenses to and indemnify
Indemnitee to the fullest extent authorized by law, against any and all
Expenses and Losses (including all interest, assessments and other charges paid
or payable in connection with or in respect of such Expenses and Losses) of
such Claim, whether or not such Claim proceeds to judgment or is settled or
otherwise is brought to a final disposition, subject in each case, to the
further provisions of this Agreement.

         3.       Limitations on Indemnification. Notwithstanding the
provisions of Section 2, Indemnitee shall not be indemnified and held harmless
from any Losses or Expenses (a) which have been Determined, as provided herein,
to constitute an Excluded Claim; (b) to the extent Indemnitee is indemnified by
the Company and has actually received payment pursuant to the Limited Liability
Company Agreement of the Company (the "LLC Agreement"), D&O Insurance, or
otherwise; or (c) other than pursuant to the last sentence of Section 4(d) or


                                       4
<PAGE>
Section 13, in connection with any Claim initiated by Indemnitee, unless the
Company has joined in or the Board of Directors has authorized such Claim.

         4.       Indemnification Procedures.

                  (a)      Promptly after receipt by Indemnitee of notice of
any Claim, Indemnitee shall, if indemnification with respect thereto may be
sought from the Company under this Agreement, notify the Company of the
commencement thereof, and Indemnitee agrees further not to make any admission
or effect any settlement with respect to such Claim without the consent of the
Company, except any Claim with respect to which the Indemnitee has undertaken
the defense in accordance with the second to last sentence of Section 4(d).

                  (b)      If, at the time of the receipt of such notice, the
Company has D&O Insurance in effect, the Company shall give prompt notice of
the commencement of Claim to the insurers in accordance with the procedures set
forth in the respective policies. The Company shall thereafter take all
necessary or desirable action to cause such insurers to pay, on behalf of
Indemnitee, all Losses and Expenses payable as a result of such Claim.

                  (c)      To the extent the Company does not, at the time of
the Claim have applicable D&O Insurance, or if a Determination is made that any
Expenses arising out of such Claim will not be payable under the D&O Insurance
then in effect, the Company shall be obligated to pay the Expenses of any Claim
in advance of the final disposition thereof and the Company, if appropriate,
shall be entitled to assume the defense of such Claim, with counsel
satisfactory to Indemnitee, upon the delivery to Indemnitee of written notice
of its election so to do. After delivery of such notice, the Company will not
be liable to Indemnitee under this Agreement for any legal or other Expenses
subsequently incurred by the Indemnitee in connection with such defense other
than reasonable Expenses of investigation; provided that Indemnitee shall have
the right to employ its counsel in such Claim but the fees and expenses of such
counsel incurred after delivery of notice from the Company of its assumption of
such defense shall be at the Indemnitee's expense; provided further that if:
(i) the employment of counsel by Indemnitee has been previously authorized by
the Company; (ii) Indemnitee shall have reasonably concluded that there may be
a conflict of interest between the Company and Indemnitee in the conduct of any
such defense; or (iii) the Company shall not, in fact, have employed counsel to
assume the defense of such action, the reasonable fees and expenses of counsel
shall be at the expense of the Company. In addition, Indemnitee shall have the
right to appeal any Determination to a court of competent jurisdiction, and if
successful shall be entitled to receive indemnification against and for Losses
and Expenses incurred in connection with such appeal.

                  (d)      All payments on account of the Company's
indemnification obligations under this Agreement shall be made within thirty
(30) days of Indemnitee's written request therefor unless a Determination is
made that the Claims giving rise to Indemnitee's request are Excluded Claims or
otherwise not payable under this Agreement, provided that all payments on
account of the Company's obligation to pay Expenses under Section 4(c) of this
Agreement prior to the final disposition of any Claim shall not be subject to
any such Determination but shall be subject to Section 4(e) of this Agreement.
In the event the Company takes the position that the Indemnitee is not entitled
to indemnification in connection with the proposed


                                       5
<PAGE>
settlement of any Claim, the Indemnitee shall have the right at its own expense
to undertake defense of any such Claim, insofar as such proceeding involves
Claims against the Indemnitee, by written notice given to the Company within
ten (10) days after the Company has notified the Indemnitee in writing of its
contention that the Indemnitee is not entitled to indemnification. If it is
subsequently determined in connection with such proceeding that the
Indemnifiable Events are not Excluded Claims and that the Indemnitee,
therefore, is entitled to be indemnified under the provisions of Section 2
hereof, the Company shall promptly indemnify the Indemnitee.

                  (e)      Indemnitee hereby expressly undertakes and agrees to
reimburse the Company for all Losses and Expenses paid by the Company in
connection with any Claim against Indemnitee in the event and only to the
extent that a Determination shall have been made by a court of competent
jurisdiction in a decision from which there is no further right to appeal that
Indemnitee is not entitled to be indemnified by the Company for such Losses and
Expenses because the Claim is an Excluded Claim or because Indemnitee is
otherwise not entitled to payment under this Agreement.

         5.       Settlement. The Company shall have no obligation to indemnify
Indemnitee under this Agreement for any amounts paid in settlement of any Claim
effected without the Company's prior written consent. The Company shall not
settle any Claim in which it takes the position that Indemnitee is not entitled
to indemnification in connection with such settlement without the consent of
the Indemnitee, nor shall the Company settle any Claim in any manner which
would impose any Fine or any obligation on Indemnitee, without Indemnitee's
written consent. Neither the Company nor Indemnitee shall unreasonably withhold
their consent to any proposed settlement.

         6.       Change in Control; Extraordinary Transactions. The Company
and Indemnitee agree that if there is a Change in Control of the Company (other
than a Change in Control which has been approved by a majority of the Company's
Board of Directors who were directors immediately prior to such Change in
Control), then all Determinations thereafter with respect to the rights of
Indemnitee to be paid Losses and Expenses under this Agreement shall be made
only by a special independent counsel (the "Special Independent Counsel")
selected by Indemnitee and approved by the Company (which approval shall not be
unreasonably withheld) or by a court of competent jurisdiction. The Company and
the Indemnitee agree that if there is a Change of Control which has been
approved by a majority of the Company's Board of Directors who were directors
immediately prior to such Change of Control then all Determinations thereafter
with respect to the rights of Indemnitee to be paid Losses and Expenses under
this Agreement shall be made by a majority vote of a quorum of disinterested
directors of the Company or, if the Company is a subsidiary of any other
Person, then by a majority vote of a quorum of disinterested directors of the
ultimate parent entity of the Company, or, in either case, by a court of
competent jurisdiction. The Company shall pay the reasonable fees of such
Special Independent Counsel and shall indemnify such Special Independent
Counsel against any and all reasonable expenses (including reasonable
attorneys' fees), claims, liabilities and damages arising out of or relating to
this Agreement or its engagement pursuant hereto.


                                       6
<PAGE>
         The Company covenants and agrees that, in the event of a Change in
Control of the sort set forth in clause (B) of Section l(c), the Company will
use its best efforts (a) to have the obligations of the Company under this
Agreement expressly assumed by the surviving, purchasing or succeeding entity,
or (b) otherwise to adequately provide for the satisfaction of the Company's
obligations under this Agreement, in a manner reasonably acceptable to the
Indemnitee.

         7.       No Presumption. For purposes of this Agreement, the
termination of any Claim by judgment, order, settlement (whether with or
without court approval) or conviction, or upon a plea of nolo contendere, or
its equivalent, shall not, of itself, create a presumption that Indemnitee did
not meet any particular standard of conduct or have any particular belief or
that a court has determined that indemnification is not permitted by applicable
law.

         8.       Non-exclusivity, Duration, Etc. The rights of the Indemnitee
hereunder shall be in addition to any other rights Indemnitee may have under
the LLC Agreement, applicable law, any vote of stockholders or disinterested
directors or otherwise, both as to action in the Indemnitee's official capacity
and as to action in any other capacity by holding such office, and the rights
and obligations under this Agreement shall continue in full force and effect
after the Indemnitee ceases to serve the Company as a director, officer,
employee, agent or fiduciary, and for so long as the Indemnitee shall be
subject to any Claim by reason of (or arising in part out of) an Indemnifiable
Event and until all applicable statutes of limitation have expired. To the
extent that a change in the applicable laws of the State of Delaware (whether
by statute or judicial decision) permits greater indemnification by agreement
than would be afforded currently under the LLC Agreement and this Agreement, it
is the intent of the parties hereto that Indemnitee shall enjoy by this
Agreement the greater benefits so afforded by such change.

         9.       Liability Insurance. To the extent the Company maintains an
insurance policy or policies providing directors' and officers' liability
insurance, Indemnitee, if an officer or director of the Company, shall be
covered by such policy or policies, in accordance with its or their terms, to
the maximum extent of the coverage available for any director or officer of the
Company.

         10.      Subrogation. In the event of payment under this Agreement,
the Company shall be subrogated to the extent of such payment to all of the
rights of recovery of Indemnitee, who shall execute all papers required and
shall do everything that may be necessary to secure such rights, including the
execution of such documents necessary to enable the Company effectively to
bring suit to enforce such rights.

         11.      Partial Indemnity, Etc. If Indemnitee is entitled under any
provision of this Agreement to indemnification by the Company for some or a
portion of the Expenses and Losses of a Claim but not, however, for the total
amount thereof, the Company shall nevertheless indemnify Indemnitee for the
portion thereof to which Indemnitee is entitled. Moreover, notwithstanding any
other provision of this Agreement, to the extent that Indemnitee has been
successful on the merits or otherwise in defense of any or all Claims relating
in whole or in part to any Indemnifiable Event or in defense of any issue or
matter therein, including dismissal without prejudice, Indemnitee shall be
indemnified against all


                                       7
<PAGE>
Expenses incurred in connection therewith. In connection with any Determination
as to whether Indemnitee is entitled to be indemnified hereunder the burden of
proof shall be on the Company to establish that Indemnitee is not so entitled.

         12.      Liability of Company. The Indemnitee agrees that neither the
stockholders nor the directors nor any officer, employee, representative or
agent of the Company shall be personally liable for the satisfaction of the
Company's obligations under this Agreement and the Indemnitee shall look solely
to the assets of the Company for satisfaction of any claims hereunder.

         13.      Enforcement.

                  (a)      Indemnitee's right to indemnification and other
rights under this Agreement shall be specifically enforceable by Indemnitee
only in the state or Federal courts of the States of California, Delaware, New
York or Tennessee and shall be enforceable notwithstanding any adverse
Determination by the Company's Board of Directors, independent legal counsel,
the Special Independent Counsel or the Company's stockholders and no such
Determination shall create a presumption that Indemnitee is not entitled to be
indemnified hereunder. In any such action, the Company shall have the burden of
proving that indemnification is not required under this Agreement.

                  (b)      In the event that any action is instituted by
Indemnitee under this Agreement, or to enforce or interpret any of the terms of
this Agreement, Indemnitee shall be entitled to be paid all court costs and
reasonable expenses, including reasonable counsel fees, incurred by Indemnitee
with respect to such action, unless the court determines that each of the
material assertions made by Indemnitee as a basis for such action were not made
in good faith or were frivolous.

         14.      Severability. In the event that any provision of this
Agreement is determined by a court to require the Company to do or to fail to
do an act which is in violation of applicable law, such provision (including
any provision within a single section, paragraph or sentence) shall be limited
or modified in its application to the minimum extent necessary to avoid a
violation of law, and, as so limited or modified, such provision and the
balance of this Agreement shall be enforceable in accordance with their terms
to the fullest extent permitted by law.

         15.      Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of Delaware applicable to
agreements made and to be performed entirely within such State, without
reference to the choice of law provisions of such State.

         16.      Consent to Jurisdiction. The Company and the Indemnitee each
hereby irrevocably consent to the jurisdiction of the courts of the States of
California, Delaware, New York and Tennessee for all purposes in connection
with any action or proceeding which arises out of or relates to this Agreement
and agree that any action instituted under this Agreement shall be brought only
in the state and Federal courts of the States of California, Delaware, New York
and Tennessee.
