         Section 1. Purpose. The purpose of the Ardent Health Services LLC and
its Subsidiaries Option and Restricted Unit Purchase Plan (the "Plan") is to
promote the interests of Ardent Health Services LLC, a Delaware limited
liability company (the "Company"), and any Subsidiary thereof and the interests
of the Company's members by providing an opportunity to selected employees,
officers, members of the Board and consultants of the Company and its
Subsidiaries as of the date of the adoption of the Plan or at any time
thereafter to purchase Units of the Company. By encouraging such ownership, the
Company seeks to attract, retain and motivate such employees and other persons
and to encourage such employees and other persons to devote their best efforts
to the business and financial success of the Company. It is intended that this
purpose will be effected by the granting of "non-qualified options" to acquire
Common Units of the Company and/or by the granting of rights to purchase Units
of the Company on a restricted or unrestricted unit basis. Under the Plan, the

which is inconsistent with Section 25102(o) shall, without further act or
amendment by the Board, be reformed to comply with the requirements of Section
25102(o).

securities pursuant to the Plan are subject to compliance with Section
260.140.45 of Title 10 of the California Code of Regulations ("Section
260.140.45"), the total number of Common Units issuable upon the exercise of all
outstanding Options (together with options outstanding under any other option
plan of the Company) or issued pursuant to an Award and the total number of
Common Units provided for under any bonus or similar plan of the Company shall
not exceed thirty percent (30%) (or such other higher percentage limitation as

is terminated for any reason, the Common Units allocable to the unexercised
portion of such Option may again be subject to an Option and/or Award granted
under the Plan. If any Units issued or sold pursuant to an Award or the exercise

Non-Qualified Option granted under the Plan shall be specified by the Committee,
in its sole discretion, and shall be set forth in a written option agreement (a
"Non-Qualified Option Agreement") between the Company and the Participant in
such form as the Committee shall approve. The terms and conditions of each
Non-Qualified Option will be such (and each Non-Qualified Option Agreement shall
expressly so state) that each Non-Qualified Option issued hereunder shall not
constitute nor be treated as an "incentive stock option" as defined in Section
422(b) of the Code, but will be a "non-qualified option" for Federal, state and
local income tax purposes. The terms and conditions of any Non-Qualified Option
granted hereunder need not be identical to those of any other Non-Qualified

Specified Participant, the terms and conditions of each Non-Qualified Option

Non-Qualified Option shall be exercisable in such amount or amounts, under such
conditions (including, without limitation, provisions governing the rights to
exercise such Non-Qualified Option), and at such times or intervals or in such
installments as shall be determined by the Committee in its sole discretion,
provided, however, that Non-Qualified Options


                                       6

granted to Participants (other than Specified Participants) shall become
exercisable at the rate of at least 20% per year over five years from the date

         "disability" (within the meaning of Section 22(e)(3) of the Code), the
         unexercised portion of any Non-Qualified Option held by such
         Participant at that time may only be exercised within 90 days after the
         date on which the Participant ceased to be an Employee, and only to the
         extent that the Participant could have otherwise exercised such
         Non-Qualified Option as of the date on which he ceased to be an
         Employee.

                  (ii) In the event a Participant shall cease to be an Employee
         of the Company or any Subsidiary of the Company by reason of his
         "disability" (within the meaning of Section 22(e)(3) of the Code), the
         unexercised portion of any Non-Qualified Option held by such
         Participant at that time may only be exercised within one year after

         within a period of one year after ceasing to be an Employee by reason
         of such "disability"), the unexercised portion of any Non-Qualified
         Option held by such Participant at the time of his death may only be
         exercised within one year after the date of such Participant's death,
         and only to the extent that the Participant could have otherwise
         exercised such Non-Qualified Option at the time of his death. In such
         event, such Non-Qualified Option may be exercised by the executor or
         administrator of the Participant's estate or by any person or persons
         who shall have acquired the Non-Qualified Option directly from the
         Participant by bequest or inheritance.

required to withhold any Federal, state or local taxes in respect of any
compensation income realized by any Participant in respect of a Non-Qualified
Option granted hereunder or in respect of any Common Units acquired upon

kind otherwise due to such Participant the aggregate amount of such Federal,
state and local taxes required to be so withheld (which amount shall be the
minimum amount required to be withheld under applicable law) or, if such
payments are insufficient to satisfy such Federal, state and local taxes, or if
no such payments are due or to become due to such Participant, then, such
Participant will be required to pay to the Company or such Subsidiary, or make
other arrangements satisfactory to the Company or such Subsidiary regarding

taxes. All matters with respect to the total amount of taxes to be withheld in

each Award granted under the Plan shall be specified by the Committee, in its

Participant, the terms and conditions of each Award shall include the following:

withhold any Federal, state or local taxes in respect of any compensation income
realized by the Participant in respect of an Award granted hereunder, in respect
of any Units acquired pursuant to an Award, or in respect of the vesting of any

retirement, resignation or dismissal with or without cause), the Company shall
have the right and option, but not the obligation, to repurchase from such
Participant (or in the case of such Participant's death, such Participant's
legal representative) any or all of the Units purchased by such Participant (or
in the case of such Participant's death, such Participant's legal
representative) within the time periods specified in Sections 8(e) and 8(f)
below.

         (b) If a Participant's employment is terminated for "cause" and the
Company exercises the right and option described in Section 8(a) above, the
Company shall pay to such Participant as the purchase price for such Units (the
"Purchase Price") (i) if such Participant is a Specified Participant, an amount
per unit equal to the lesser of the fair market value thereof as of the date
such Participant ceased to be so employed by the Company or any Subsidiary of
the Company and the original purchase price such Participant paid for the Units
(the "Original Price") and (ii) if such Participant is not a Specified
Participant, an amount per unit equal to the Original Price.

         (c) If a Participant's employment is terminated for any reason other
than "cause" and the Company exercises the right and option described in Section
8(a) above, the Company shall pay to such Participant as the Purchase Price, an
amount per Unit equal to the fair market value thereof as of the date of such
termination.

         (d) Fair market value of Units will be determined in good faith by the
Board on a basis consistent with the manner of determining the fair market value
of the Company's equity securities for purposes of offering of the Company's
equity securities to equity investors.

         (e) The Company may exercise the right and option described in Section
8(a) above with respect to Units held by a Specified Participant by giving such
Specified Participant (or in the case of such Specified Participant's death,
such Specified Participant's legal representative) a written notice of election
to purchase at any time within 60 days after the date (i) that such Specified
Participant's employment ceases, in the event such Participant (A) has owned the
Units to be repurchased for at least six months or (B) has been terminated for
"cause", or (ii) that is the six month anniversary after such Specified
Participant acquired the Units to be repurchased, in the event such Specified
Participant has not owned the Units for at least six months as of the date such
Specified Participant ceased to be so employed and such Specified Participant's
employment was terminated for any reason other than "cause." The notice of
election shall specify the number of Units to be purchased and the Purchase
Price for such Units. In the event that a Specified Participant (or in the case
of such Specified Participant's death, such Specified Participant's legal
representative) exercises an Option and acquires any additional Units on any
date after the date such notice of election is provided by the Company, then the
Company may again exercise the right and option described in Section 8(a) above
by giving such Specified Participant (or in the case of such Specified
Participant's death, such Specified Participant's legal representative) a
written notice of election to purchase at any time within 60 days after the date
of such exercise, which notice of election shall specify the number of Units to
be purchased and the Purchase Price for such Units.

         (f) The Company may exercise the right and option described in Section
8(a) above with respect to a Participant (other than a Specified Participant) by
giving such Participant (or in the case of such Participant's death, such
Participant's legal representative) a written notice of election to purchase at
any time within (x) 90 days after the date that such Participant's employment
terminates or, in the case of Units issued upon exercise of Options after the
date of termination, (y) 90 days after the date of such exercise. The notice of
election shall specify the number of Units to be purchased and the Purchase
Price for such Units. Notwithstanding anything in this Section 8 to the
contrary, the Company's right and option to purchase Units from Participants
(other than Specified Participants) as described in Section 8(b)(ii) above (i)
shall lapse at the rate of twenty percent (20%) of the Common Units subject to
such repurchase right per year over the five years from the date the Option is
granted (without respect to the date the


                                       10

Option was exercised or became exercisable) and (ii) shall terminate in the
event the Company's equity securities become publicly traded.

         (g) The closing for the purchase by the Company of Units pursuant to
the provisions of this Section 8 will take place at the offices of the Company
on the date specified in the written notice of election with respect to such
Units, which date shall be a business day not later than 30 days after the date
such notice is given. At such closing, such Participant will deliver such Units,
duly endorsed for transfer, against payment in cash of the Purchase Price
thereof.

         (h) In the event that the Company chooses not to exercise its right and
option under Section 8(a) hereof, with respect to any Unit, such Unit shall
thereafter cease to be subject to the repurchase provisions of this Section 8.

         Section 9. Adjustments. (a) In the event that, after the adoption of
the Plan by the Board, the outstanding Units shall be increased or decreased or
changed into or exchanged for a different number or kind of equity interests or
other securities of the Company or of another entity, in each such case through
reorganization, merger or consolidation, recapitalization, reclassification,
stock split, split-up, combination or exchange of units or declaration of any
dividends or other distribution payable in Units, the Committee in good faith
shall, subject to the provisions of Section 9(c) below if the circumstances
therein specified are applicable, appropriately adjust (i) the number of Common
Units (and the option price per Common Unit) subject to the unexercised portion
of any outstanding Option (to the nearest possible full Common Unit), (ii) the
number of Units to be acquired pursuant to an Award which have not become
vested, and (iii) the number of Units for which Options and/or Awards may be
granted under the Plan, as set forth in Section 4.1 hereof, and such adjustments
shall be effective and binding for all purposes of the Plan.

         (b) If any capital reorganization or reclassification of the Common
Units of the Company or any consolidation or merger of the Company with another
entity, or the sale of all or substantially all its assets to another entity,
shall be effected in such a way that holders of Common Units shall be entitled
to receive stock, securities or assets with respect to or in exchange for Common
Units, then, subject to the provisions of Section 9(c) below if the
circumstances therein specified are applicable, each holder of an Option shall
thereafter have the right to purchase, upon the exercise of the Option in
accordance with the terms and conditions specified in the option agreement
governing such Option and in lieu of the Common Units immediately theretofore
receivable upon the exercise of such Option, such shares of stock, securities or
assets (including, without limitation, cash) as may be issued or payable with
respect to or in exchange for a number of outstanding Common Units equal to the
number of Common Units immediately theretofore so receivable had such
reorganization, reclassification, consolidation, merger or sale not taken place.

         (c) Notwithstanding Sections 9(a) and 9(b) hereof, in the event of (i)
any offer to holders of the Common Units generally relating to the acquisition
of all or


                                       11
<PAGE>

substantially all of their Common Units, including, without limitation, through
purchase, merger or otherwise, or (ii) any proposed transaction generally
relating to the acquisition of substantially all of the assets or business of
the Company (herein sometimes referred to as an "Acquisition"), the Board may,
in its sole discretion, cancel any outstanding Options and pay or deliver, or
cause to be paid or delivered, to the holder thereof an amount in cash or
securities having a value (as determined by the Board acting in good faith)
equal to the product of (A) the number of Common Units that, as of the date of
the consummation of such Acquisition, the holder of such Option had become
entitled to purchase (and had not purchased) multiplied by (B) the amount, if
any, by which (1) the formula or fixed price per Common Unit paid to holders of
Common Units pursuant to such Acquisition exceeds (2) the option price
applicable to such Common Units.

         Section 10. Effect of the Plan on Employment Relationship; Grants to
Employees of Subsidiaries. (a) Neither the Plan nor any Option and/or Award
granted hereunder to a Participant shall be construed as conferring upon such
Participant any right to continue in the employ of (or otherwise provide
services to) the Company or any Subsidiary of the Company, or limit in any
respect the right of the Company or any Subsidiary of the Company to terminate
such Participant's employment or other relationship with the Company or any
Subsidiary, as the case may be, at any time.

         (b) In the event of the exercise of any Option and/or Award under the
Plan by an employee of any Subsidiary of the Company, it is understood (i) that
the Units to be acquired pursuant to such exercise shall be deemed to have been
transferred from the Company to such Subsidiary at the time of such exercise and
from such Subsidiary to such employee, (ii) that the exercise price or other
consideration payable by such employee to the Company in respect of such Option
and/or Award shall be deemed to have been paid by such employee to such
Subsidiary and by such Subsidiary to the Company and (iii) that at the time of
any such exercise, such Subsidiary shall pay to the Company an amount of cash
equal to the excess of the fair market value of such Units over such exercise
price or other consideration.

         Section 11. Amendment of the Plan. The Board may amend the Plan from
time to time as it deems desirable.

         Section 12. Termination of the Plan. The Board may terminate the Plan
at any time. Unless the Plan shall theretofore have been terminated by the
Board, the Plan shall terminate ten years after the date of its initial adoption
by the Board. No Option and/or Award may be granted hereunder after termination
of the Plan. The termination or amendment of the Plan shall not alter or impair
any rights or obligations under any Option and/or Award theretofore granted
under the Plan.
