NOTE 1 - ORGANIZATION

NextHealth, Inc. is a leading provider of wellness and preventive health care
services in diverse retail markets. For over ten years, the Company has
developed effective treatment models which address individual wellness and
quality of life issues through a whole person, mind-body approach.

The Company operates in two distinct business segments. The Treatment segment
includes Sierra Tucson, Inc. ("STI"), a state licensed, special psychiatric
hospital and behavioral health care center for the treatment of substance abuse
and mental health disorders, including eating disorders and dual diagnosis and
Onsite Workshops, Inc. ("Onsite"), which offers short-term therapeutic
experiences and workshops. (See Note 3.) The Health and Leisure segment includes
Miraval(TM), a unique vacation experience blending stress management and
self-discovery programs in a luxury health resort environment, which opened in
late 1995 and Hilton Head Health Institute, Inc. ("HHHI"), a provider of weight
management programs for the development and maintenance of healthy lifestyles as
well as fitness, nutrition, stress management and other lifestyle change
programs, acquired in March 1996. (See Note 3.)

NOTE 2 - BASIS OF PRESENTATION

The unaudited consolidated financial statements presented herein should be read
in conjunction with the consolidated financial statements and notes thereto
included in the Company's Annual Report on Form 10-K for the year ended December
31, 1995. The accompanying interim consolidated financial statements as of
September 30, 1996 and for the three and nine-month periods ended September 30,
1996 and 1995 included herein are unaudited, but reflect, in the opinion of
management, all adjustments (consisting of normal recurring adjustments)
considered necessary to fairly present the results for such periods. Operating
results for the three and nine-month periods ended September 30, 1996 are not
necessarily indicative of the results that may be expected for the year ended
December 31, 1996.

NOTE 3 - DIVESTITURES

On October 18, 1996, the Company announced the divestiture of Onsite Workshops,
Inc. and Hilton Head Health Institute in order to further reduce corporate
overhead, eliminate long-term debt obligations and focus on its two primary
lines of business, Miraval and Sierra Tucson, Inc. The Onsite sale, which was
completed on November 30, 1996, was made to the original owners in exchange for
the assumption of existing obligations. Goodwill of $281,000 recorded in
connection with the Onsite acquisition was written-off in anticipation of this
sale. The HHHI was purchased by NextHealth's President and Chief Executive
Officer, John Schmitz on October 1, 1996 for cash of $275,000 and assumption of
certain debt obligations, including the purchase of real property, such that no
gain or loss was realized by the Company on the sale. The Company guarantees up
to $130,000 of any loss related to the sale of the real property by John Schmitz
to an unaffiliated third party. The HHHI sales transaction was recorded in the
accompanying September 30, 1996 financial statements. This transaction was
reviewed and approved by an independent committee of the Company's Board of
Directors. In considering the divestiture of these two lines of business, the
Board concluded that neither offered a significant long-term profit potential
when compared to Miraval and Sierra Tucson, Inc. In addition, the divestitures
have a minimal impact on the Company's financial position, operations or cash
flow.

NOTE 4 - FINANCING TRANSACTIONS

On April 10, 1996, the Company obtained a $2,000 line of credit (the "LOC") from
the National Bank of Arizona for a term of six months. The LOC had a variable
interest rate based upon the prime rate as published in the Western Edition of
the Wall Street Journal plus 1 percent. The initial interest rate was 9.25%,
payable in monthly installments. The LOC was secured by certain real estate
owned by the Company. The LOC was paid off in full with the proceeds from the
$4,000 financing mentioned below.

On April 3, 1996, the Company negotiated an agreement with Sundt Corporation
("Sundt"), the general contractor of the Miraval project, for the payment of
approximately $3,700, which represented the remaining balance due Sundt at that
date for the construction of Miraval. This agreement has a term of eighteen
months and bears interest at an annual rate equal to the prime rate as
established by Bank One, N.A. plus 4 percent. Sundt received a $300 payment at
the closing of the LOC and will receive payments of $125 per month for a period
of eleven months commencing in May 1996. The balance remaining after the
aforementioned payments will be paid evenly in six monthly installments. Sundt
has agreed to subordinate the master Mechanics' Lien recorded against Miraval's
real property on March 28, 1996 to the LOC and additional borrowings up to
$5,000. Additionally, as part of this agreement, if the Company were to obtain
secured borrowings in excess of $5,000 or unsecured borrowings in excess of
$3,000, the unpaid balance due Sundt would immediately become due. At December
31, 1995, the amount due Sundt was classified as accounts payable, construction.
At June 30, 1996, as a result of the agreement negotiated with Sundt, the
long-term portion of this obligation has been classified as long-term debt.

On June 28, 1996, the Company amended its agreement with Sundt to facilitate the
closing of the $4,000 financing noted below. Sundt received an additional $100
payment in connection with this amendment.

On June 28, 1996, the Company secured financing in the amount of $4,000 with
Mortgages Ltd. Principal and interest at 13.75% is payable in monthly
installments of $53 through March, 1998 at which time all unpaid principal is
due and payable. The financing is collateralized by certain real estate and
property, plant and equipment owned by the Company. Proceeds were used to repay
the existing balance on the LOC and to assist with meeting short-term working
capital requirements.

On November 15, 1996, the Company completed separate equity and debt
transactions with affiliates of Apollo Real Estate Advisors, L.P. (See Part II,
Item 5). Both Sundt and Mortgages Limited were paid in full. See discussion in
the "Liquidity and Capital Resources" section.

         RESULTS OF OPERATIONS

GENERAL

NextHealth, Inc. is a leading provider of wellness and preventive health care
services in diverse retail markets. For over ten years, the Company has
developed effective treatment models which address individual wellness and
quality of life issues through a whole person, mind-body approach.

The Company operates in two distinct business segments. The Treatment segment
includes Sierra Tucson, Inc., a state licensed, special psychiatric hospital and
behavioral health care center for the treatment of substance abuse and mental
health disorders, including eating disorders and dual diagnosis and Onsite,
which offers short-term therapeutic experiences and workshops. The Health and
Leisure segment includes Miraval, a unique vacation experience blending stress
management and self-discovery programs in a 106 room luxury health resort
environment, which opened in late 1995 and HHHI, a provider of weight management
programs for the development and maintenance of healthy lifestyles as well as
fitness, nutrition, stress management and other lifestyle change programs which
was acquired in March 1996. Agreements to sell both Onsite and HHHI were
executed after September 30, 1996.

The Company, as part of its long range plan, believes that it has positioned
itself to capitalize on the newly emerging health and leisure segment of the
health care services industry by developing Miraval, a luxury health resort
providing a full range of self-discovery, stress management and recreational
activities. For the nine-month period ended September 30, 1996, the Treatment
segment accounted for approximately 62% of all the Company's operating revenues
and approximately 37% of operating expenses while the Health and Leisure segment
accounted for approximately 37% of the Company's operating revenue and
approximately 46% of operating expenses. However, the Company believes that the
Health and Leisure segment will make significant contributions to the Company's
operating results in the future.

</TABLE>

(1) HHHI was acquired effective March 1, 1996.

(2) Miraval commenced operations in December 1995. Complimentary guest days of
    334 are included in the stated figures.

For the three-month period ended September 30, 1996, the loss before income tax
benefit and net loss decreased from $3.5 million in 1995 to $3.3 million in
1996. Net cash provided by operating activities was $334,000 in 1995 compared to
net cash used in operating activities of $902,000 in 1996.

Total net revenue increased $1.0 million to $4.3 million, an increase of 30%
when compared to the same period in 1995. Results reflect commencement of
operations at Miraval and the acquisition of HHHI. This increase was offset by a
decrease in investment income attributable to the use of cash and investments
for the development of Miraval.

Salaries and related benefits increased $1.7 million to $3.7 million, an
increase of 89% when compared to the same period in 1995. The increase was
primarily due to staffing requirements related to the operations at Miraval.

General and administrative expense increased $1.1 million to $3.0 million, an
increase of 59% when compared to the same period in 1995. The increase was due
primarily to operational costs related to Miraval. This increase was partially
offset by a decrease in general and administrative expense of $356,000 at Sierra
Tucson, Inc.

The Company recognized a pre-tax loss of $3.3 million for the three-month period
ended September 30, 1996.

No provision or benefit for income taxes was recorded during this period. The
Company will be able to carry forward the current period loss to offset future
tax liabilities.

(1) HHHI was acquired effective March 1, 1996 and was sold on October 1, 1996.

(2) Miraval commenced operations in December 1995. Complimentary guest days of
    1,895 are included in the stated figures.

For the nine-month period ended September 30, 1996, net loss increased $3.4
million to $8.6 million and net cash provided by operating activities decreased
$14.0 million resulting in net cash used in operating activities of $6.7 million
compared to the same period in 1995.

Total net revenue increased $2.7 million to $13.8 million, an increase of 24%
when compared to the same period in 1995. Results reflect commencement of
operations at Miraval and the acquisition of HHHI. This increase was offset by a
decrease in investment income attributable to the use of cash and investments
for the development of Miraval.

Salaries and related benefits increased $5.4 million to $11.2 million, an
increase of 94% when compared to the same period in 1995. The increase was
primarily due to staffing requirements related to the operations at Miraval.

General and administrative expense increased $3.0 million to $8.8 million, an
increase of 51% when compared to the same period in 1995. The increase was
primarily due to operational costs related to Miraval. The Company recognized a
pre-tax loss of $8.6 million for the nine-month period ended September 30, 1996.
No provision or benefit for income taxes was recorded during this period. The
Company will be able to carry forward the current period loss to offset future
tax liabilities.

LIQUIDITY AND CAPITAL RESOURCES

The Company's primary sources of liquidity and capital resources have typically
been cash provided by the Treatment segment's operating activities and funds
generated from the sale of investments and proceeds from public equity
offerings. Historically, these sources have been sufficient to meet the needs
and finance the operations and growth of the Company's business. Net cash
provided by the Treatment segment's operating activities has been primarily
affected by census levels and net revenue per patient day. This segment
contributed positive cash flow to the Company's operations during the three and
nine-month periods ended September 30, 1996.

Primarily as a result of operating expenditures required to support the Health
and Leisure segment until it is self sufficient, the Company's cash from
operations has decreased significantly. For the three-month period ended
September 30, 1996, the Company's net cash used in operating activities was
$902,000.

For the nine-month period ended September 30, 1996 the Company had net capital
expenditures of approximately $1.1 million. Primarily as a result of operating
expenditures required to support the Health and Leisure segment until it is
self-sufficient and the aforementioned capital expenditures, the Company's cash
reserves have decreased significantly. For the nine-month period ended September
30, 1996 the Company's net cash used in operating activities was $4.3 million.

The Treatment segment's operational results for the three-month period ended
September 30, 1996 reflect the segment's focus on attracting a high percentage
of retail patients. During this period, 74% of patient revenue was derived from
retail payments and the remaining 26% from third party payors. STI continues to
experience pressure from third party payors and managed care organizations to
restrict patient access to and payment for treatment services. Based on current
census levels and operating expenses, STI believes that it will generate
adequate cash flows to sustain the Treatment segment's ongoing operational
requirements.

Miraval, the Company's Health and Leisure segment's primary line of business,
commenced operations in December 1995. This segment's results are primarily
affected by occupancy, average annual room rates and the segment's ability to
manage costs. Miraval believes that it operates in a unique niche in an emerging
health and leisure market. Marketing and advertising initiatives for creating
marketplace awareness and demand for Miraval's services resulted in a room
occupancy rate of approximately 31% through September 30, 1996 of which 83% were
paying guests and 17% non-paying guests. As part of the segment's marketing
strategy, media, travel and trade representatives as well as other key
influencers have been invited to experience Miraval with the anticipation that
Miraval will be promoted in the marketplace. Management believes the Health and
Leisure segment will, in time, make a significant contribution to the Company's
financial condition. However, until such time that it generates positive cash
flow, short and long-term financing and the implementation of cost containment
measures will be necessary to sustain its operations.

To meet its current liquidity requirements, the Company entered into debt and
equity financing transactions. (See Item 5.) The financing transactions closed
on November 15, 1996. The proceeds from the transactions were approximately
$12,340,000. The source and use of funds are as follows:

</TABLE>

(1)     Funds were placed in escrow to avoid a prepayment penalty of
        approximately $158,000. The funds placed in escrow will be used to pay
        off the principal balance on January 4, 1997. The Company expects to
        receive approximately $260,000 from the escrow monies after paying off
        the balance on January 4, 1997.

(2)     The funds available to meet operating cash requirements and alleviate
        net working capital deficit will be utilized to bring trade accounts
        payable and other current liabilities up to a current status. After
        disbursing the funds necessary to bring trade payables and other current
        liabilities to a current status, the Company expects to have
        approximately $1,500,000 in cash (cash on hand) available to meet future
        operating cash requirements.

The debt financing transaction (see Item 5) contains certain provisions related
to a stand by commitment for an additional $5,000,000. To the extent that cash
on hand is not enough to meet future operating cash requirements, the stand by
funds will be utilized to provide the cash necessary to fund future operating
cash requirements.

The Company must receive shareholder approval for certain items related to the
equity financing transaction (see Item 5). If shareholder approval of these
items is not obtained prior to March 15, 1997, the debt of $8,090,000 becomes
immediately due and payable as well as any accrued interest thereon and the
$4,250,000 of Preferred Stock is redeemable at the option of the holders, out of
funds legally available therefor. To the extent that shareholder approval is not
obtained related to those items required in the equity financing transaction,
this would create an immediate and significant liquidity crisis for the Company.
The effect of this potential liquidity crisis would have a major impact on the
Company's ability to continue operations.

Also, in order to alleviate current liquidity requirements, it is necessary for
the Company to increase occupancy levels and to implement additional cost
controls. Insufficient occupancy levels at Miraval or any significant decrease
in STI's patient levels would adversely affect the Company's financial position,
results of operations and cash flows. Management does not anticipate any
significant impact upon operations as a result of inflation, nor has the Company
historically experienced any such impact.

BUSINESS OUTLOOK

In 1997, the Company expects to realize a contribution to net income and cash
flow from its primary lines of business -- Treatment and Health & Leisure.

Performance in the Treatment segment (Sierra Tucson, Inc.) will be driven by
continued aggressive implementation of cost controls and new marketing
initiatives. Particular emphasis will be placed on increasing the number of
self-pay patients through a combination of innovative treatment programs and
focused advertising, direct mail, field sales and outbound telemarketing
campaigns.

Recently introduced programs such as Recovery Plus(TM) and Sierra Care(TM) will
continue to be promoted to major referent and retail market sectors, and will
likewise be introduced to the corporate marketplace. Recovery Plus(TM) is a
unique product which ensures that a chemically-dependent patient who relapses
during the first six months following discharge will be readmitted for an
additional 10-14 days at a very modest per diem rate. This program is the first
of its kind in the treatment field, and visible evidence of STI's commitment to
the long-term recovery of each patient, and the proven effectiveness of the
Sierra Model(TM).

Sierra Care(TM) is an all-inclusive addictions package which provides the
patient with the tools necessary to


                                       13
<PAGE>   14
meet their recovery goals within a 24 day time frame -- and at a substantially
reduced cost. Sierra Care(TM) is designed for addiction patients with a lower
acuity on the mental health diagnosis, and those who fall more into a straight
chemical dependency diagnosis.

STI will continue its traditional marketing efforts to the referent therapist
community, and look for the continued double-digit growth of prospective
patients which has characterized the third quarter of 1996.

Miraval, the Company's initial entry in the Health & Leisure category, has now
been in operation for nine months, and appears poised for steadily improving
performance in 1997. The resort has received extensive press coverage in such
diverse media as CNN, InStyle, Gourmet, and Vogue magazine (to name a few), and
has likewise gained a high level of awareness among consumers and travel
professionals.

Management's primary objective for Miraval in 1997 is to build short and
long-term occupancy levels while maintaining our unique program structure and
operational excellence. Marketing initiatives will be aimed primarily at upscale
consumers and top-echelon travel agents as well as corporate and incentive
groups. The Miraval message will be delivered through a blend of direct sales
and advertising -- including print, data base-driven direct mail, and public
relation activities.

Cost containment measures will continue to be a critical management objective in
1997. Variable staffing relative to seasonal occupancy fluctuations, a more
structured program format, and self-directed internal work teams focusing on all
aspects of operational quality should further improve efficiencies and cash
flow.

FACTORS THAT MAY AFFECT FUTURE RESULTS

Management's Discussion and Analysis of Results of Operations and Financial
Condition contains forward looking statements within the meaning of the Private
Securities Litigation Reform Act of 1995 that involve a number of risks and
uncertainties. While management believes that such forward looking statements
are accurate as of the date hereof, the actual results and conditions could
differ materially from the statements contained herein. The information below
should be read in conjunction with the Company's unaudited consolidated
financial statements and related notes thereto included elsewhere and in other
portions of this document.

In addition, the following other factors could cause actual results and
conditions relating to liquidity and capital resources to differ materially.

Miraval represents a new and significant line of business for the Company.
Miraval is the Company's initial entry into a unique niche in the emerging
health and leisure market for which there is little, if any, industry market
data available. Its products and services are different than those of
traditional destination resorts or destination "spa" facilities. The Company has
little experience in the marketing, management or operation of a facility of
this nature, although it has hired qualified and experienced personnel from
related operations.

The Company is unable to project with any degree of accuracy the future
occupancy levels or revenues of Miraval because the facility is in its first
year of operation. The Company has no historical operating data for projecting
occupancy levels during peak and non-peak periods, marketing, operating or
maintenance costs and expenses. Although the Company believes that there is
strong consumer demand for Miraval's products and services because it represents
a unique vacation alternative, the Company cannot be certain that its current
marketing strategy will successfully attract the targeted clientele.

The Company cannot be certain that Miraval will generate sufficient revenues to
cover its operating expenses. Management believes that the existing capital
resources of the Company are insufficient to meet its short-term capital needs.
Additional capital may be available through short and long-term financing;
however, the Company cannot predict the terms or availability of such financing.

Miraval competes in the competitive resort hotel/spa industry. In many
instances, its competitors have greater name recognition and financial resources
as well as long-standing relationships with travel agents and tour and trip
planners. Management cannot anticipate what impact this will have on future
occupancy levels.


                                       14
<PAGE>   15
The entities comprising the Company's Treatment segment participate in the
highly competitive mental and behavioral health industry characterized by
intense competition for market share resulting from aggressive pricing practices
and increasing competition from companies with greater resources, including tax
exempt, non-profit status, government subsidized or endowment-related financial
support which may provide lower costs of capital.

While the Company anticipates continued growth in revenues and is committed to a
return to profitability, operating results could be adversely impacted if the
businesses are unable to anticipate customer demand accurately, are unable to
differentiate their products from those of their competitors, are unable to
offer services expeditiously in response to customer demand, or are negatively
impacted by managed care restrictions on payor reimbursement.

The Company must receive shareholder approval for certain items related to the
equity financing transaction (see Item 5). If shareholder approval of these
items is not obtained prior to March 15, 1997, the debt of $8,090,000 becomes
immediately due and payable as well as any accrued interest thereon and the
$4,250,000 of Preferred Stock is redeemable at the option of the holders, out of
funds legally available therefor. To the extent that shareholder approval is not
obtained related to those items required in the equity financing transaction,
this would create an immediate and significant liquidity crisis for the Company.
The effect of this potential liquidity crisis would have a major impact on the
Company's ability to continue operations.

                           PART II - OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

The Company is involved in various litigation and administrative proceedings
arising in the normal course of business. In the opinion of management, any
liabilities that may result from these claims will not, individually or in the
aggregate, have a material adverse effect on the Company's financial position,
results of operations or cash flows.

ITEM 2.  CHANGES IN SECURITIES

See Item 5 - Other Information - "Financing Transaction".

ITEM 5.  OTHER INFORMATION

                             Financing Transactions

As discussed in previous public filings, the costs of construction of Miraval,
the introduction of a significant new business line and ongoing operating losses
during the continuing period of strategic transition substantially reduced the
Company's capital resources and severely affected its liquidity. After exploring
alternative mechanisms to finance its capital needs, on November 15, 1996
("Transaction Date"), the Company completed separate equity and debt
transactions with affiliates of Apollo Real Estate Advisors, L.P. ("Apollo")
that resulted in the Company's receipt of approximately $12,340,000 in cash and,
subject to compliance with certain conditions, a $5,000,000 loan commitment (the
"Apollo Transactions"). The Apollo Transactions consisted of: (a) the sale to AP
NH LLC, a Delaware limited liability company ("APNH") pursuant to a Preferred
Stock and Warrant Purchase Agreement (the "Purchase Agreement") of (I) shares of
two series of Preferred Stock for an aggregate purchase price of $4,250,000 (the
"Preferred Stock Transaction") and (ii) a warrant (the "Warrant") to purchase
500,000 shares of the Company's Common Stock, $0.01 par value ("Common Stock")
and (b) a secured loan in the amount of $13,090,000 (the "Debt Transaction")
with AP LOM LLC, a Delaware limited liability company ("APLOM"). The Debt
Transaction includes a $5,000,000 stand-by loan commitment, subject to
compliance with certain conditions, (the "Stand-by Commitment").

On October 11, 1996 the Company signed a Letter of Interest ("Letter of
Interest") with Apollo which outlined the terms of the debt and equity
financings represented by the Apollo Transactions. Because of the Company's
financial condition at the time, an affiliate of Apollo provided a short-term
working capital line of credit of $750,000; of which, $500,000 had been borrowed
and was repaid at the Transaction Date with the proceeds from the Apollo
Transactions. In addition, the Apollo affiliate received a warrant to purchase
100,000 shares of Common Stock at an exercise price of $1.50 per share. The
average closing price of the common stock during the 20 trading days prior to
October 11, 1996 was $1.266. The closing prices of the Common Stock on October
11, 1996 and on the Transaction Date were $1.75 and $2.06 per share,
respectively.

The net proceeds from the funded portion of the Apollo Transactions were used to
retire certain short-term and working capital obligations (approximately
$5,000,000), pay-off the balance due to the general contractor for Miraval
(approximately $2,680,00) and the balance to fund immediate cash flow
requirements and provide working capital for the continued operations of Miraval
until it can be operated at a profit. The Stand-by Commitment, if available
pursuant to its terms, will be used to support the Company's operations and the
long-term expansion of Miraval.

The Preferred Stock Transaction consisted of the sale of 17,109 shares of
Preferred Stock, Series A ("Series A Preferred Stock") at a price of $92.26 per
share ($1,578,476, in the aggregate) and 28,956 shares of Cumulative Preferred
Stock, Series B ("Series B Preferred Stock") at a price of $92.26 per share
($2,671,480, in the aggregate). At the time of their issuance, the shares of the
Series A Preferred Stock represented approximately 19.9% of outstanding voting
power of the Company. Although APNH desired to purchase Series



                                       16
<PAGE>   17
A Preferred Stock having voting rights of up to 35% of the shares of outstanding
Common Stock, because of the provisions of Rule 4460(I) of the NASDAQ Stock
Market ("NASDAQ"), the Company does not intend to issue additional shares of
Series A Preferred Stock until stockholder approval is obtained. NASD Rule
4460(I) provides that sales of securities by a company listed on NASDAQ/NMS
having or representing 20% or more of the outstanding voting power on the date
of issuance for less than current market price or book value must be first
approved by the stockholders.

The Company's stockholders are being asked to approve the issuance to APNH of an
additional 28,956 shares of Series A Preferred Stock ("Proposed Issuance"). If
the Company's stockholders approve such issuance, the 28,956 outstanding shares
of Series B Preferred Stock will be automatically converted into a like number
of shares of Series A Preferred Stock.

The Company retained the services of Victor Capital to review the terms of the
Apollo Transactions and advise the Board of Directors on the fairness of such
terms. After considering and based upon the Company's financial condition, the
alternative sources of capital available at the time, and other conditions
affecting the Company, Victor Capital advised the Board that the financial terms
of the Apollo Transactions are commercially reasonable and therefore fair to the
Company and its stockholders from a financial point of view.

Description of Preferred Stock Transaction

Immediately prior to the Transaction Date, the Company's Board of Directors
created two series of Preferred Stock consisting of 46,065 shares of Series A
Preferred Stock and 28,956 shares of Series B Preferred Stock. The following is
a summary of the respective designations, preferences and rights of the Series A
and Series B Preferred Stock as set forth in the Certificate of Designation,
Preference and Rights filed with the State of Delaware, Office of the Secretary
of State ("Series Designation"). Reference herein to "Preferred Stock" shall
include Series A Preferred Stock and Series B Preferred Stock.

1. Dividends. The holders of Series A Preferred Stock are not entitled to
receive dividends except upon an event of default as defined in the Series
Designation in which event, the dividend rate on the Series A Preferred Stock
will be 18% per annum. The holders of Series B Preferred Stock are entitled to
receive cumulative, preferred dividends at the rate of 12% per annum from
January 1, 1997 to January 31, 1997 and at the rate of 18% per annum from
February 1, 1997 and thereafter and upon a Default of the provisions of the
Series Designation.

So long as any shares of Preferred Stock remain outstanding, the Company may not
declare or pay any cash dividend or make any other distributions with respect to
the Common Stock.

2. Liquidation Preference. In the event of any liquidation, dissolution or
winding-up of the Company, the holders of Preferred Stock shall be entitled to a
liquidation preference over the holders of Common Stock in the amount of any
accrued but unpaid dividends. There are no other liquidation preferences.

3. Voting Rights. The holders of Series B Preferred Stock do not possess any
voting rights. The holders of Series A Preferred Stock are entitled to vote on
all matters presented to the Company's stockholders for a vote and, except with
respect to the election of Directors, each share of Series A Preferred Stock
shall entitle the holder thereof to such number of votes per share as shall
equal the number of shares of the Common Stock into which such share of Series A
Preferred Stock is then convertible. Initially, each share of Series A Preferred
Stock is convertible into 100 shares of Common Stock. In addition, the holders
of Series A Preferred Stock are entitled to vote separately as a separate class
on all matters other than the election of directors. This means that matters
submitted for a vote of the stockholders of the Company must receive the
approval of the requisite percentage of the holders of Common Stock (with the
holders of Series A Preferred Stock being entitled to vote on an "as converted"
basis) as well as of the holders of the Series A Preferred Stock.

In addition, the holders of Series A Preferred Stock, as a class, are entitled
to elect four directors to the Company's Board of Directors ("Preferred
Directors").


                                       17
<PAGE>   18
Upon the occurrence of an event of default as defined in the Series Designation,
the holders of Series A Preferred Stock will become entitled to elect a majority
of the Company's Board of Directors.

A majority vote of the holders of the outstanding Series A Preferred Stock
voting as a separate class is required in order to approve certain transactions
including: (I) the amendment of the Company's Certificate of Incorporation so as
to adversely affect the rights of the holders of Series A Preferred Stock or any
of the provisions of the Certificate of Designation; (ii) authorize, create or
issue any class of capital stock that is senior to or pari passu with the Series
A Preferred Stock or (iii) enter into a transaction having a total value in
excess of $250,000 per transaction except under certain conditions.

As part of the Apollo Transactions, effective on the Transaction Date, the
Company's Board of Directors was expanded from five to nine persons and the
following Preferred Directors were elected to represent the holder of Series A
Preferred Stock: Lee S. Neibart, W. Edward Scheetz, Bruce Spector and Alfred C.
Trivilino.

4. Conversion of Series B Preferred Stock into Series A Preferred Stock. Each
share of Series B Preferred Stock is automatically converted into Series A
Preferred Stock, on a one for one basis, upon the approval by a majority of the
total votes cast by the stockholders of the Company of the issuance of
additional shares of Series A Preferred Stock in excess of 17,109 shares
("Stockholder Approval").

Each share of Series B Preferred Stock will be convertible, at the option of the
holder, into one share of Series A Preferred Stock after March 15, 1997, unless
Stockholder Approval has been obtained. The Series Designation also provides
that the Series B Preferred Stock is convertible, at the option of the holders
thereof, into Series A Preferred Stock if the stockholders of the Company have
not approved an amendment to the Company's Certificate of Incorporation deleting
Article 9 thereof on or before June 15, 1997. Article 9 imposes a 66 2/3%
affirmative stockholder voting requirement in connection with certain change of
control transactions such as a merger, consolidation, sale of all or
substantially all of the assets of the Company, etc. APNH, as the holder of the
Series B Preferred Stock has waived the operation of this provision until such
time as it gives not less than 90 days written request to the Company to present
a proposal to the stockholders to delete Article 9. The stockholders of the
Company must approve the deletion of Article 9 (and other related provisions)
within 90 days of such notice.

5. Conversion of Series A Preferred Stock into Common Stock. As of the date
hereof, each share of Series A Preferred Stock is convertible into 100 shares of
Common Stock or 1,710,900 shares in the aggregate. Shares of Series B Preferred
Stock are not convertible into Common Stock. The number of shares of Common
Stock issuable upon conversion of the Series A Preferred Stock is subject to
adjustment to reflect certain transactions affecting the Common Stock such as
the issuances of Common Stock at less than $0.9226 per share, stock dividends,
splits, reverse splits, etc. Upon Stockholder Approval, each of the 28,956
shares of Series B Preferred Stock will be automatically converted into one
share of Series A Preferred Stock. Such additional shares of Series A Preferred
Stock will be convertible into 2,895,600 shares of Common Stock.

6. Redemption. Commencing on January 1, 2001, the Company may, at its option,
redeem shares of Preferred Stock at a price per share equal to the redemption
price of $92.26 per share ("Redemption Price") plus all accrued but unpaid
dividends.

If Stockholder Approval has not been obtained on or before March 15, 1997, the
holders of Preferred Stock have the option to require the Company to redeem all
or any portion of their Preferred Stock at a price equal to the Redemption Price
plus all accrued and unpaid dividends.

Unless and until Stockholder Approval is obtained, upon a "change in control" as
defined in the Series Designation, the holders of Preferred Stock shall have the
option to require the Company to redeem all but not less than all of their
shares of Preferred Stock at a price equal to the greater of 200% of the
Redemption Price or the fair market value of the aggregate number of shares of
Common Stock into which such shares of Preferred Stock are convertible on the
effective date of such change in control. A change of control includes the
acquisition of 20% or more of the outstanding voting stock of the Company, the
merger or consolidation or sale of substantially all of the assets of the
Company or if the Preferred Directors cease to


                                       18

constitute at least forty percent (40%) of the Board of Directors.

Unless and until Stockholder Approval is obtained, upon the occurrence of any
default as described below ("Default"), the holders of Series A and Series B
Preferred Stock shall have the option to require the Company to redeem all but
not less than all of the shares of Preferred Stock held by such person at a
price equal to the Redemption Price plus all accrued but unpaid dividends.
Events of default include the failure to pay dividends for any two quarterly
periods, a default of the Purchase Agreement and the passage of fifteen days
thereafter, or a default under the Credit Agreement relating to the Debt
Transaction.

The Company anticipates that a meeting of the stockholders will be held prior to
March 15, 1997 in order to consider the issuance of 28,956 shares of Series A
Preferred Stock to APNH. The Company has been advised that the shares of Common
Stock beneficially owned by Messrs. William T. O'Donnell, Jr. (2,240,078 shares)
and John H. Schmitz (296,684 shares) will be voted to approve such issuance. In
additional, APNH is required to vote its shares of Series A Preferred Stock
(representing 1,710,900 votes) to approve such issuance.

Other Provisions

The Purchase Agreement requires the approval of a majority of the Preferred
Directors in connection with certain matters presented to the Board of Directors
including annual budgets and operating forecasts of the Company; and
transactions with affiliates. In addition, APNH has the right to approve all
future nominations to the Board of Directors other than those individuals
serving as directors on the Transaction Date.

Warrant

The Warrant entitles APNH to purchase 500,000 shares of Common Stock at an
exercise price of $1.50 per share. The Warrant is exercisable only on or after
March 15, 1997 and before November 14, 2006. The exercise price of and number of
shares purchasable under the Warrant are subject to adjustment to reflect
certain transactions affecting the Common Stock such as issuances of Common
Stock at less than $1.50 per share, stock dividends, splits, reverse splits,
etc.

Debt Transaction

The Debt Transaction was made pursuant to a Credit Agreement ("Credit
Agreement") between the Company and APLOM and consisted of a loan funded on the
Transaction Date in the principal amount of $8,090,000 together with a
$5,000,000 standby commitment subject to compliance with certain conditions. The
promissory notes evidencing the Debt Transaction ("Promissory Notes") bear
interest at the rate of 10% per annum during the first year; 11% during the
second year and 12% during the third year. The interest rate increases to 18%
per annum upon the occurrence of an event of default (as defined in the Credit
Agreement) or on February 1, 1997 (retroactive to November 15, 1996) if
Stockholder Approval has not been obtained by that date. The Promissory Notes
mature on the third anniversary of the Transaction Date but, the Promissory
Notes become immediately due and payable if Stockholder Approval has not been
obtained on or before March 15, 1997.

The obligations and indebtedness under the Credit Agreement and Promissory Notes
("Credit Documents") are secured by a deed of trust to essentially, all of the
land and buildings of the Company, a security interest in all of the Company's
and its subsidiaries (including Soften) ("Subsidiaries") personal property and
by the collateral pledge of the Company's stock or other interest in the
Subsidiaries. In addition, each of the Subsidiaries guaranteed performance of
the Credit Documents.

GENERAL EFFECTS OF PREFERRED TRANSACTION ON COMMON STOCKHOLDERS

The Preferred Stock Transaction significantly impacts the rights of existing
stockholders. Since the Series A Preferred Stock is convertible into Common
Stock and currently has voting rights and because the Preferred Directors
effectively have a veto right with respect to certain matters presented to the
Board of Directors for a vote, the voting rights of the current stockholders are
diluted.



                                       19
<PAGE>   20
All matters presented to the Company's stockholders for a vote, other than the
election of directors, must receive the requisite percentage approval of the
holders of Series A Preferred Stock as well as of the holders of Common Stock
(with the holders of Series A Preferred Stock voting with the Common
stockholders on an "as converted" basis).

In addition, the Series A Preferred Stock is convertible into Common Stock at
the current conversion rate of 100 shares of Common Stock for each share of
Series A Voting Preferred Stock. Upon conversion of the Series B Preferred Stock
into Series A Voting Preferred Stock (if stockholders approve the Proposed
Issuance), there will be 46,065 shares of Series A Voting Preferred Stock
outstanding which will be convertible into 4,606,500 shares of Common Stock
representing approximately 35% of the outstanding Common Stock on the date
hereof. As indicated above, if Stockholder Approval has not been obtained on or
before March 15, 1997, each share of Series B Preferred Stock is convertible
into one share of Series A Preferred Stock at the option of the holder thereof.

The issuance of Series A Preferred Stock will also have a dilutive effect on the
holders of Common Stock because it was sold at an equivalent price per share of
Common Stock less than the then current market price and book value of the
Common Stock. Series A Preferred Stock is convertible into Common Stock at an
equivalent conversion price of $0.9226 per share of Common Stock. The average
closing price of the Common Stock during the 20 trading days prior to October
11, 1996 was $1.266. The closing prices of the Common Stock on October 11, 1996
and on the Transaction Date were $1.756 and $2.06 per share, respectively.
Although the shares of Common Stock issuable on conversion of the Series A
Preferred Stock or on exercise of the Warrant are subject to a Registration and
Pre-Emptive Rights Agreement granting APNH certain piggy-back and demand
registration rights (the "Registration Rights Agreement"), such shares are
restricted and may not be publicly traded at this time without registration
pursuant to the Securities Act of 1933.

The Registration Rights Agreement grants APNH the right to purchase additional
shares of capital stock as necessary to allow it to maintain its proportionate
interest in the Company.

                    Transfer of Assets of Sierra Tucson, Inc.

Based on its analysis of the Company's business structure, Apollo recommended
that the assets of Sierra Tucson, the Company's treatment center for substance
abuse, addictions and other behavioral health disorders, be sold to a newly
formed entity, partially owned by APNH. Consequently, on November 13, 1996, the
assets of Sierra Tucson were sold to Soften Realty, L.L.C., a Delaware limited
liability company ("Soften") for $8,000,000. The purchase price is evidenced by
Soften's non-negotiable promissory note which is secured by a security interest
in the assets of Sierra Tucson. Such assets consist of the business of Sierra
Tucson, the tangible and intangible assets used in connection with the business
and a possessory right to use certain land and buildings owned by the Company.
The Company is the manager of and owns a 98% interest in Soften; the remaining
2% is owned by APNH.

The Board of Directors recognized that the transfer of Sierra Tucson's assets to
Soften would facilitate the operations and utilization of the business and
strengthen its identity as a separate and distinct business operation. In
addition, it will provide greater flexibility to the Company in the development
of strategic alternatives for Sierra Tucson.

                               Management Changes

On November 14, 1996, John H. Schmitz resigned as the Company's President, Chief
Executive Officer and Chief Financial Officer and as a director. The Company's
Chairman of the Board and founder, Mr. William T. O'Donnell, Jr., was appointed
acting Chief Executive Officer and President and Ms. Loree Thompson was
appointed as acting Chief Financial Officer. Mr. Stephen Berger was elected to
fill the vacancy created by the resignation and to serve the remaining term of
Mr. Schmitz. Mr. Berger is a partner in the Chicago law firm of Neal, Gerber and
Eisenberg.

Immediately following the closing of the Preferred Stock Transaction, the Board
of Directors of the Company increased the size of the Board to nine persons and
elected the following persons as directors of the Company: Lee S. Neibart, W.
Edward Scheetz, Bruce Spector and Alfred C. Trivilino. Each of the Preferred
Directors is affiliated with Apollo.

power and authority and all material licenses, permits and authorizations

      reasonable.

               (iv) If, at the time of enforcement of any of the provisions of
      this Section 6(f), a court holds that the restrictions stated herein are
      unreasonable under the circumstances then existing, the parties hereto
      agree that the maximum period, scope or geographical area reasonable under
      such circumstances shall be substituted for the stated period, scope or
      area.

the requirements of Section 704(c) of the Code and the Treasury Regulations
thereunder.

                  (c) The following special allocations shall, except as
otherwise provided, be made in the following order:

                           (1) Except as otherwise provided in Treasury
         Regulations Section 1.704-2(f), notwithstanding any other provision of
         this Section 15, if there is a net decrease in partnership minimum gain
         or partner nonrecourse debt minimum gain (within the meaning of
         Treasury Regulations Section 1.704-2) during any taxable period, items
         of income and gain for such taxable period (and, if necessary,
         subsequent taxable periods) shall be allocated among the Members in
         accordance with Treasury Regulations Sections 1.704-2(d), 1.704-2(f),
         1.704-2(g) and 1.704- 2(i). The items to be so allocated, and the order
         in which such items must be allocated, shall be determined in
         accordance with Treasury Regulations Section 1.704-2(j)(2). This
         Section 15(c)(1) is intended to comply with the minimum gain chargeback
         requirements set forth in Treasury Regulations Section 1.704-2 and
         shall be interpreted consistently therewith.

                           (2) If any Member unexpectedly receives an
         adjustment, allocation, or distribution described in Treasury
         Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), then items of
         income and gain shall be specially allocated to such Member in
         accordance with the requirements of Treasury Regulations Section 1.704-
         1(b)(2)(ii)(d). This Section 15(c)(2) is intended to comply with the
         "qualified income offset" provision of the Regulation last cited and
         shall be interpreted consistently therewith.

                           (3) Nonrecourse deductions (within the meaning of
         Treasury Regulations Section 1.704-2(b)(1)) for any fiscal year or
         other period shall be allocated among the Members under Treasury
         Regulations Section 1.704-2(e) in accordance with the Members'
         respective Ownership Percentages.

                           (4) Any partner nonrecourse deductions (within the
         meaning of Treasury Regulations Section 1.704-2(i)) for any period
         shall be allocated to the Member that bears an economic risk of loss
         with respect to the partner nonrecourse debt (within the meaning of
         Treasury Regulations Section 1.704-2(b)(4)) to which such partner
         nonrecourse deductions are attributable, all in accordance with the
         principles of Treasury Regulations Section 1.704-2(i)(1) and (2).

                  (d) If any interest in the Company is transferred, or upon the
admission or withdrawal of a Member, in accordance with the provisions of this
Agreement, the income or loss attributable to such interest in the Company for
such calendar year shall be 


                                      -5-
<PAGE>   6
divided and allocated ratably between the Members on a daily basis; provided,
however, that, to the extent permitted by the applicable provisions of the Code
and Treasury Regulations, for all Company items which are reasonably determined
to be "extraordinary items" by the Members, applying the principles of Treasury
Regulations Section 1.1502- 76(b)(2)(ii)(C), any such extraordinary item shall
be allocated solely to the parties owning interests in the Company as of the
date such item is required to be taken into account by the Company for federal
income tax purposes.

                  (e) Any "excess nonrecourse liabilities" (as defined in
Treasury Regulations Section 1.752-3(a)(3)) shall be allocated among the Members
in accordance with their respective Ownership Percentages.

                  (f) To the extent an adjustment to the adjusted tax basis of
any Company asset pursuant to Code Section 734(b) or Code Section 743(b) is
required, pursuant to Treasury Regulations Section 1.704-1(b)(2)(iv)(m), to be
taken into account in determining Capital Accounts, the amount of such
adjustment to the Capital Accounts shall be treated as an item of gain or loss
and such gain or loss shall be specially allocated to the Members in accordance
with Treasury Regulations Section 1.704-1(b)(2)(iv)(m).

         16. Distributions. Distributions shall be made to the Members at the
times and in the aggregate amounts determined by the Members pursuant to 
Section 17. Such distributions shall be allocated among the Members in the same
proportion as their then Ownership Percentages.

         17. Management.

         (a) In accordance with Section 18-402 of the Act, management of the
Company shall be vested in the Members. The Members shall have the power to do
any and all acts necessary, convenient or incidental to or for the furtherance
of the purposes described herein, including all powers, statutory or otherwise,
possessed by members of a limited liability company under the laws of the State
of Delaware. All decisions regarding the management of the Company shall be
determined by a majority vote, or written consent in lieu of a meeting, of the
Members, as determined in accordance with their respective Ownership
Percentages. Notwithstanding any provisions herein to the contrary, the Members
may delegate to one or more Members of the Company responsibility for the
day-to-day operation of the Company.

         (b) Without the prior consent of all of the Members (which consent
shall not be unreasonably withheld), the Company shall not:

                                  (i) amend, alter or repeal any of the
                 provisions of the Company's Certificate of Formation, or this
                 Agreement, so as to adversely affect any right, preference or
                 voting power of any Member;


                                      -6-
<PAGE>   7
                                  (ii) authorize, create or issue any class or
                 series of equity security of the Company that is senior to or
                 pari passu with the limited liability company interests of the
                 Members of the date hereof (the "Existing LLC Interests");

                                (iii) enter into any transaction or series of
                  transactions having a total value in excess of $250,000 per
                  transaction or series of related transactions, or grant or
                  consent to, or otherwise permit, any amendment to, supplement
                  of, or waiver under, any agreement or contract with any
                  affiliate;

                                 (iv) consolidate with or merge into, or
                  transfer all or substantially all of its assets to, another
                  person unless (A) in the case of a merger or consolidation,
                  the Company is the surviving entity, the rights and
                  preferences of the Existing LLC Interests are not modified and
                  the Company, as the surviving entity, does not have
                  outstanding any equity security of the Company that is senior
                  to or pari passu with the Existing LLC Interests, or (B) (I)
                  the surviving, resulting or acquiring person is a person
                  organized under the laws of the United States, any state
                  thereof or the District of Columbia, or a person organized
                  under the laws of a foreign jurisdiction whose equity
                  securities are listed on a national securities exchange in the
                  United States or authorized for quotation on the NASDAQ
                  National Market System, and (II) the Company shall make
                  effective provision such that, upon consummation of such
                  transaction, the Members shall receive equity securities of
                  the surviving entity having substantially identical terms as
                  the Existing LLC Interests, and the surviving, resulting or
                  acquiring person do not have outstanding any equity security
                  that is senior to or pari passu with the Existing LLC
                  Interests; or

                                  (v) (A) incur any additional indebtedness
                  (excluding trade payable and accrued expenses incurred in the
                  ordinary course of business) not outstanding on the date
                  hereof in excess of $250,000 or (B) enter into
                  any acquisition, financing or other transaction or series of
                  related transactions having a total value in excess of
                  $250,000.

         18. Other Business. The Members and any person or entity affiliated
with any of the Members may engage in or possess an interest in other business
ventures (unconnected with the Company) of every kind and description,
independently or with others. None of the Company or the other Members shall
have any rights in or to such independent ventures or the income or profits
therefrom by virtue of this Agreement.

         19. Exculpation and Indemnification. No Member shall be liable to the
Company, any other Members or any other person or entity who has an interest in
the Company for any loss, damage or claim incurred by reason of any act or
omission performed or omitted by such Member in good faith on behalf of the
Company and in a manner reasonably believed to be within the scope of the
authority conferred on such Member by this 


                                      -7-
<PAGE>   8
Agreement, except that a Member shall be liable for any such loss, damage or
claim incurred by reason of such Member's gross negligence or willful
misconduct. To the full extent permitted by applicable law, a Member shall be
entitled to indemnification from the Company for any loss, damage or claim
incurred by such Member by reason of any act or omission performed or omitted by
such Member in good faith on behalf of the Company and in a manner reasonably
believed to be within the scope of the authority conferred on such Member by
this Agreement, except that no Member shall be entitled to be indemnified in
respect of any loss, damage or claim incurred by such Member by reason of gross
negligence or willful misconduct with respect to such acts or omissions;
provided, however, that any indemnity under this Section 19 shall be provided
out of and to the extent of Company assets only, and no Member shall have
personal liability on account thereof.

         20. Assignments. A Member may not assign, transfer or otherwise dispose
of in whole or in part its limited liability company interest without the
written consent of the other Members. If a Member transfers all of its interest
in the Company pursuant to the preceding sentence, the transferee shall be
admitted to the Company upon its execution of an instrument signifying its
agreement to be bound by the terms and conditions of this Agreement. Such
admission shall be deemed effective immediately prior to the transfer, and,
immediately following such admission, the transferor Member shall cease to be a
member of the Company. In such event, the Company shall not dissolve if the
business of the Company is continued without dissolution in accordance with
Section 23(d) hereof.

         21. Resignation. A Member may not resign or retire as a Member of the
Company without the written consent of the other Members. A Member which resigns
or retires in contravention of this Agreement shall be liable to the Company for
any damages occasioned by such resignation or retirement and, in addition to any
remedies the Company may have at law or in equity, the Company may offset
against any amounts it may owe to such resigning or retiring Member (in
connection with a distribution or otherwise) any such damages occasioned by such
resignation or retirement. If a Member is permitted to resign pursuant to this
Section 21, an additional member shall be admitted to the Company, subject to
Section 22 hereof, upon its execution of an instrument signifying its agreement
to be bound by the terms and conditions of this Agreement. Such admission shall
be deemed effective immediately prior to the resignation, and, immediately
following such admission, the resigning Members shall cease to be a member of
the Company. In such event, the Company shall not dissolve if the business of
the Company is continued without dissolution in accordance with Section 23(d)
hereof.

         22. Admission of Additional Members. One or more additional members of
the Company may be admitted to the Company with the written consent of the
Members pursuant to Section 17.


         23. Dissolution. The Company shall dissolve, and its affairs shall be
wound up upon the earliest to occur of the following:

                  (c) the sale of all or substantially all of the assets of the
         Company;

                  (d) the death, retirement, resignation, bankruptcy, court
         declaration of incompetence with respect to, or dissolution of a
         Member, unless the remaining Members agree by unanimous vote to admit
         one or more new members and unless the business of the Company is
         continued by the consent of all of the remaining members of the Company
         within 60 days following the occurrence of any such event; and

                  (e) the entry of a decree of judicial dissolution of the
         Company under Section 18-802 of the Act.

         24.      Liquidation Upon Dissolution.

                  (a) Upon the dissolution of the Company, sole and plenary
authority to effectuate the liquidation of the assets of the Company shall be
vested in NextHealth and, in the event of NextHealth's resignation, dissolution,
liquidation or bankruptcy, in a liquidator to be appointed upon the written
consent of the other Members holding a majority of the remaining Ownership
Percentages, (the "Liquidator"). The Liquidator shall have full power and
authority to sell, assign and encumber any and all of the Company's assets and
to wind up and liquidate the affairs of the Company in an orderly and
business-like manner.

                  (b) The Liquidator shall determine, in its sole discretion,
the fair market value of all assets of the Company as at the date of
distribution of such assets and the profits and losses resulting from such
distribution shall be allocated in accordance with Section 15 hereof.

                  (c) The proceeds of liquidation of the assets of the Company
distributable upon a dissolution and winding up of the Company shall be applied
in the following order of priority:

                           (1) first, to the creditors of the Company, including
         creditors who are Members, in the order of priority provided by law, in
         satisfaction of all liabilities and obligations of the Company (of any
         nature whatsoever, including, without limitation, fixed or contingent,
         matured or unmatured, legal or equitable, secured or unsecured),
         whether by payment or the making of reasonable provision for payment
         thereof; and

                           (2) thereafter, in accordance with the Capital
         Accounts of the Members.

         25.      Tax Matters


                                      -9-
<PAGE>   10
                  (a) NextHealth shall, on behalf of the Company, arrange,
supervise and oversee the preparation and timely filing, and prior review by
independent certified public accountants, of all returns of Company income,
gain, deductions, losses, credits and other items necessary for federal, state,
local and foreign income tax purposes and shall use all reasonable efforts to
furnish to the Members, within 90 days after the close of the taxable year, the
tax information reasonably required for federal, state, local and foreign income
tax reporting purposes. The taxable year of the Company shall be the calendar
year unless another year is required by the Code (the "Company Year").

                  (b) NextHealth shall be the "Tax Matters Partner," as such
term is defined in Section 6231(a)(7) of the Code. In the event of an income tax
audit of any tax return of the Company, the filing of any amended return or
claim for refund in connection with any item of income, gain, loss, deduction or
credit reflected on any tax return of the Company, or any administrative or
judicial proceedings arising out of or in connection with any such audit,
amended return, claim for refund or denial of such claim, (i) the Tax Matters
Partner shall be authorized to act for, and its decision shall be final and
binding upon, the Company and all the Members (it being understood that the Tax
Matters Partner shall not agree to waive or extend any statute of limitations
without the consent of Apollo, which consent shall not be unreasonably
withheld), (ii) all expenses incurred by the Tax Matters Partner in connection
therewith (including, without limitation, attorneys', accountants' and other
experts' fees and disbursements) shall be expenses of the Company and (iii) no
other Members shall have the right to (A) participate in the audit of any
Company tax return, (B) file any amended return or claim for refund in
connection with any item of income, gain, loss, deduction or credit reflected on
any tax return of the Company, (C) participate in any administrative or judicial
proceedings arising out of or in connection with any such audit, amended return,
claim for refund or denial of such claim, or (D) appeal, challenge or otherwise
protest any adverse findings in any such audit or with respect to any such
amended return or claim for refund or in any such administrative or judicial
proceedings. Each Member agrees to indemnify and hold harmless the Company and
all other Members from and against any and all liabilities, obligations,
damages, deficiencies and expenses resulting from (y) any tax liability incurred
by the Company attributable to such Member, including, without limitation, any
liability incurred by the Company for failure to withhold taxes on distributions
to such Member or (z) any breach or violation by such Members of the provisions
of this Section 25, and from all actions, suits, proceedings, demands,
assessments, judgments, costs and expenses, including reasonable attorneys' fees
and disbursements, incident to any such liability, breach or violation.

         26.      Miscellaneous.

                  (a) Each provision of this Agreement shall be considered
separable and if for any reason any provision or provisions herein are
determined to be invalid, unenforceable or illegal under any existing or future
law, such invalidity, unenforceability or illegality shall not impair the
operation of or affect those portions of this Agreement which are valid,
enforceable and legal.

the parties hereto with respect to the subject matter hereof, and supersedes all
prior understandings or agreements between the parties.

be governed by, and construed under, the laws of the State of Delaware, without
regard to the conflicts of law principles thereof.

or amended except pursuant to a written agreement executed and delivered by all
of the Members.

                              W I T N E S S E T H:

         WHEREAS, pursuant to the Secured Promissory Note of Grantor dated
November 13, 1996 (as the same may be amended, supplemented or otherwise
modified from time to time, the "Note") Secured Party has made loans aggregating
$8,000,000 (the "Loans") to Grantor;

         WHEREAS, as a condition to Secured Party making such Loans to Grantor,
Grantor has agreed to grant to Secured Party a security interest in the
Collateral (as hereinafter defined); and

         WHEREAS, capitalized terms, unless otherwise defined herein, are used
herein with the same meanings given to such terms in the Note.

         NOW, THEREFORE, in consideration of the foregoing and for good and
valuable consideration, receipt, adequacy and sufficiency of which is hereby
acknowledged by Grantor, the parties hereto, intending legally to be bound,
hereby agree as follows:


I.       GRANT OF SECURITY INTEREST; REMEDIES

         1.1 Security Interests. As security for all of its obligations as
Borrower under the Note, including, without limitation, the obligation to make
payment when due of all principal of and interest on the Loans, (collectively,
the "Obligations"), Grantor hereby pledges, assigns, transfers, sets over and
delivers to Secured Party and grants to Secured Party a security interest in all
of its right, title and interest in and to the Collateral.

         "Collateral" shall mean all of the assets and properties of Grantor and
all other personal property of Grantor, tangible and 
<PAGE>   2
intangible, wherever located or situated and whether now owned or hereafter
acquired or created, including without limitation, all goods, accounts,
documents, instruments, chattel paper, inventory, contract rights, general
intangibles and equipment and any proceeds thereof or income therefrom.

         1.2 Use of Collateral. So long as no Event of Default shall have
occurred and be continuing, and subject to the various provisions of this
Agreement and the Note, Grantor may use and dispose of the Collateral in any
lawful manner.

         1.3 Application of Proceeds. Upon the request of Secured Party during
the continuation of an Event of Default, Grantor agrees to take all steps
necessary to cause all sums, monies, royalties, fees, commissions, charges,
payments, advances, income, profit, and other proceeds constituting proceeds of
the Collateral to be applied to the satisfaction of the Obligations.

         1.4 Collections, etc. Upon the occurrence of an Event of Default, and
during the continuation of such Event of Default, Secured Party may, in its sole
discretion, in its name or in the name of Grantor or otherwise, demand, sue for,
collect or receive any money or property at any time payable or receivable on
account of or in exchange for, or make any compromise or settlement deemed
desirable with respect to, any of the Collateral, but shall be under no
obligation to do so, or Secured Party may, to the fullest extent permitted by
applicable law extend the time of payment, arrange for payment in installments,
or otherwise modify the terms of, or release, any of the Collateral, without
thereby incurring responsibility to, or discharging or otherwise affecting any
liability of Grantor. Secured Party will not be required to take any steps to
preserve any rights against prior parties to the Collateral. If Grantor fails to
make any payment or take any action required hereunder, Secured Party may, after
notice to Grantor, make such payments and take all such actions as Secured Party
reasonably deems necessary to protect Secured Party's security interest in the
Collateral and/or the value thereof, and Secured Party is hereby authorized
(without limiting the general nature of the authority hereinabove conferred) to
pay, purchase, contest, or compromise any encumbrances, charges or liens that in
the judgment of Secured Party appear to be equal to, prior to or superior to the
security interest of Secured Party in the Collateral and any Liens not expressly
permitted by this Agreement.

         1.5      Possession, Sale of Collateral, etc.

                  (a) Upon the occurrence of an Event of Default, and during the
continuation of such Event of Default, to the extent permitted by applicable
law, Secured Party may enter upon the premises of Grantor, or wherever the
Collateral may be, and take possession of the Collateral, and may reasonably
demand and receive such possession from any Person who has possession thereof,
and Secured Party may take such measures as it may deem necessary or proper for
the care or protection thereof, including, without limitation, the rights to
remove all or any portion of the Collateral, and with or without taking such
possession may sell or cause to be sold, whenever Secured Party shall decide, in
one or more sales or parcels, at such prices as Secured Party may deem best, and
for cash or on credit or for future delivery, without assumption of any credit
risk, all or any portion of the Collateral, at any broker's board or at public
or private sale, without demand of performance or notice of intention to sell or
of time or place of sale (except 10 days' written notice to Grantor of the time
and place of such sale or sales and such other notices as may be required by
applicable law and cannot be waived), and any person or entity may be the
purchaser of all or any portion of the Collateral so sold and thereafter hold
the same absolutely, free from any claim or right of whatever kind, including
any equity of redemption of Grantor, any such demand, notice, claim, right or
equity being hereby expressly waived and released to the extent permitted by
applicable law.

                  (b) At any sale or sales made pursuant to this Article I,
Secured Party may bid for or purchase, free (to the fullest extent permitted by
applicable law) from any claim or right of whatever kind, including any equity
of redemption of Grantor (any such demand, notice, claim, right or equity being
hereby expressly waived and released) any part of or all of the Collateral
offered for sale, and may make any payment on account thereof by using any claim
for moneys then due and payable to Secured Party with respect to the Obligations
as a credit against the purchase price. Secured Party shall in any such sale
make no representations or warranties with respect to the Collateral or any
part thereof, and Secured Party shall not be chargeable with any of the
obligations or liabilities of Grantor.

                  (c) Grantor hereby agrees (i) that it will indemnify and hold
Secured Party harmless from and against any and all claims


                                      -3-
<PAGE>   4
with respect to the Collateral asserted before the taking of actual possession
or control of the Collateral by Secured Party pursuant to this Article I, or
arising out of any act of, or omission to act on the part of, any party other
than Secured Party prior to such taking of actual possession or control by
Secured Party, or arising out of any act on the part of Grantor, or its agents
before or after the commencement of such actual possession or control by Secured
Party; and (ii) Secured Party shall have no liability or obligation to Grantor
arising out of any such claim except for acts of willful misconduct or gross
negligence. In any action hereunder, Secured Party shall be entitled to the
appointment of a receiver without notice, to take possession of all or any
portion of the Collateral and to exercise such powers as the court shall confer
upon the receiver.

                  (d) Notwithstanding the foregoing, upon the occurrence of an
Event of Default, and during the continuation of such Event of Default, Secured
Party shall be entitled to apply, without prior notice to Grantor, any cash or
cash items constituting Collateral in the possession of Secured Party to payment
of that portion of the Obligations secured hereby.

         1.6 Application of Proceeds on Default. Upon the request of Secured
Party after the occurrence of an Event of Default, all income on the Collateral,
and all proceeds from any sale of the Collateral pursuant hereto shall be
applied (in such order as Secured Party shall in its sole discretion determine)
to the payment in full of the Obligations of Grantor to Secured Party. Any
amounts remaining after such payment in full shall be remitted to Grantor or as
a court of competent jurisdiction may otherwise direct.

         1.7 Power of Attorney. Upon the occurrence of an Event of Default and
during the continuation of such Event of Default, (a) Grantor does hereby
irrevocably make, constitute and appoint Secured Party or any of its officers or
designees its true and lawful attorney-in-fact with full power in the name of
Secured Party or such other person or entity to endorse any notes, checks,
drafts, money orders or other evidences of payment relating to the Collateral
that may come into the possession of Secured Party, and to do any and all other
acts necessary or proper to carry out the intent of this Agreement and the grant
of the security interests hereunder and thereunder, and Grantor hereby ratifies
and confirms all that Secured Party or its substitutes shall properly do by



                                      -4-
<PAGE>   5
virtue hereof; and (b) Grantor does hereby further irrevocably make, constitute
and appoint Secured Party or any of its officers or designees its true and
lawful attorney-in-fact in the name of Secured Party or Grantor (i) to enforce
Grantor's rights under and pursuant to all agreements with respect to the
Collateral, all for the sole benefit of Secured Party, (ii) to enter into and
perform such agreements as may be necessary in order to carry out the terms,
covenants and conditions of this Agreement that are required to be observed or
performed by Grantor, (iii) to execute such other and further mortgages, pledges
and assignments of the Collateral, and related instruments or agreements, as
Secured Party may reasonably require for the purpose of perfecting, protecting,
maintaining or enforcing the security interests granted to Secured Party
hereunder, and (iv) to do any and all other things necessary or proper to carry
out the intention of this Agreement and the grant of the security interests
hereunder.

         1.8 Financing Statements, Direct Payments, Confirmation of Receivables
and Audit Rights. So long as the Obligations are outstanding, Grantor hereby
authorizes Secured Party to file UCC financing statements and any amendments
thereto or continuations thereof and any other documents or instruments and to
give any notices necessary or desirable to perfect the lien of Secured Party on
the Collateral, in all cases with regard to the Collateral without the
signatures of Grantor or to execute such items as attorney-in-fact for Grantor.
Grantor further authorizes Secured Party, upon the occurrence of an Event of
Default and during the continuation of such Event of Default, (i) to notify any
account debtors that all sums payable to Grantor relating to the Collateral
shall be paid directly to Secured Party and (ii) to confirm with any account
debtors the amounts payable by them to Grantor with regard to the Collateral and
to participate with Grantor in the audits of its account debtors. Secured Party
hereby agrees to provide Grantor with copies of any notification or written
requests sent by Secured Party to such account debtors at the same time as the
mailing of such documents.

         1.9 Termination. The security interests granted under this Article I
shall terminate when all the Obligations have been fully paid and performed, and
the Commitment shall have terminated. Upon such termination Secured Party will
take, at the expense of Grantor, all action and do all things reasonably
necessary to release the security interest granted to it hereunder.

         1.10 Remedies Not Exclusive. The remedies conferred upon or reserved to
Secured Party in this Article I are intended to be in addition to, and not in
limitation of, any other remedy or remedies available to Secured Party. Without
limiting the generality of the foregoing, Secured Party shall have all rights
and remedies of a secured creditor under Article 9 of the Uniform Commercial
Code as enacted in the State of Arizona.

SECTION 5.        REPRESENTATIONS AND COVENANTS OF PURCHASER

                  The Purchaser hereby represents and warrants to the

                  (a) The execution of this Agreement has been duly authorized
by all necessary action on the part of the Purchaser; this Agreement has been
duly executed and delivered by the Purchaser; and this Agreement constitutes a
valid, binding and enforceable agreement of the Purchaser.

with a view to any "distribution" thereof within the meaning of the Securities
Act.

                  (c) Purchaser understands that because the Preferred Stock,
the Warrant and the Warrant Stock have not been registered under the Securities

the Warrant Stock unless such securities are subsequently registered under the

acknowledges and understands that, except as provided in the Registration Rights

and the Corporation, it has no independent right to require the Corporation to
register the Preferred Stock, the Common Stock issuable upon conversion of
shares of Series A Preferred Stock, the Warrant or the Warrant Stock. The
Purchaser further understands that the Corporation may, as a condition to the
transfer of any of the Preferred Stock, the Common Stock issuable upon
conversion of shares of Series A Preferred Stock, the Warrant or the Warrant
Stock, require that a written request for transfer be delivered to the
Corporation accompanied by an opinion of counsel, in form and substance
satisfactory to the Corporation, to the effect that the proposed transfer does
not result in a violation of the Securities Act or that such transfer is covered
by an effective registration statement under the Securities Act. The Purchaser
understands that each certificate representing the Preferred Stock and the
Warrant will bear the following legend or one substantially similar thereto:

         "THIS SECURITY AND SHARES ISSUABLE ON CONVERSION OR EXERCISE OF THIS

         EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT AND APPLICABLE STATE
         SECURITIES LAWS OR AN EXEMPTION THEREFROM UNDER SUCH ACT OR LAWS."

                  (d) The Purchaser is knowledgeable and experienced in the
making of equity investments, and is able to bear the economic risk of loss of
its investment in the Corporation.

                  (e) The Purchaser has been advised that the shares of
Preferred Stock and the Warrant issued hereunder have not been and are not being
registered under the Securities Act or under the "blue sky" laws of any
jurisdiction (except in the case of certain state filings) and that the
Corporation in issuing the Preferred Stock and the Warrant is relying upon,
among other things, the representations and warranties of Purchaser contained in
this Section 5 in concluding that each such issuance is a "private offering" and
does not require compliance with the registration provisions of the Securities
Act.

                  (f) The Purchaser has adequate means of providing for its
current needs and possible contingencies, has no need for liquidity of its
investment in the Preferred Stock or the Warrant and can bear the economic risk
of losing its entire investment therein.

                  (g) The Purchaser is controlled by or under common control
with Apollo Real Estate Advisors II, L.P.

         The Purchaser covenants and agrees to vote the Series A Preferred Stock
in favor of the stockholder proposals referred to in Section 4.3.

of dealing between the Corporation and the Purchaser and no delay on the part of
any party hereto in exercising any rights hereunder or thereunder shall operate
as a waiver of the rights hereof and thereof. No covenant or other provision
hereof or thereof may be waived otherwise than by a written instrument signed by
the party so waiving such covenant or other provision. Any amendment or waiver
effected in accordance with this Section 6.2 shall be binding upon each holder

                               PRE-EMPTIVE RIGHTS

         Section 1  PRE-EMPTIVE RIGHT.

         (a) In the event of future issuances of New Securities by the
Corporation, the Corporation hereby grants to Apollo a right to purchase
additional shares of capital stock sufficient (the "Sufficient Number") to
maintain Apollo's percentage ownership interest in the Corporation, at a price
equal to the offering price of such additional shares of capital stock. Apollo's
percentage ownership interest, for purposes of this Section 3.1(a), shall equal
a fraction, the numerator of which is the number of shares of Common Stock then
held by Apollo or issuable upon conversion or exercise of any Shares,
convertible securities, options, rights or warrants then held by Apollo, and the
denominator of which is the total number of shares of Common Stock then
outstanding plus the number of shares of Common Stock issuable upon conversion
or exercise of then outstanding Preferred Stock, convertible securities,
options,


                                      -2-
<PAGE>   3
rights or warrants. The rights granted to Apollo pursuant to this Article 3
shall expire on December 31, 2006.

         (b) In the event the Corporation intends to issue New Securities, it
shall give Apollo written notice of such intention, describing the type of New
Securities to be issued, the price thereof and the general terms upon which the
Corporation proposes to effect such issuance. Apollo shall have 20 days from the
date of any such notice to agree to purchase up to the Sufficient Number of
shares of additional New Securities for the price and upon the general terms and
conditions specified in the Corporation's notice by giving written notice to the
Corporation stating the quantity of such New Securities to be so purchased.
Apollo shall have a right of overallotment such that if any other person or
entity entitled to pre-emptive rights fails to exercise his or its right to
purchase his or its total number of shares of additional New Securities to which
he or it is entitled, Apollo may purchase the portion not purchased by such
other person or entity on a pro rata basis (based upon the relative percentage
ownership interests of Apollo and those other investors exercising their
overallotment right), by giving written notice to the Corporation within five
days from the date that the Corporation provides written notice to the other
investors of the amount of New Securities with respect to which such
nonpurchasing investor has failed to exercise its or his right hereunder.


                                   ARTICLE 4.

                               REGISTRATION RIGHTS

                  1 OPTIONAL REGISTRATIONS. If at any time or times after the
date hereof, the Corporation shall determine to register any of its Common Stock
or securities convertible into or exchangeable or exercisable for Common Stock
under the Securities Act (whether in connection with a public offering of
securities by the Corporation (a "primary offering"), a public offering thereof
by shareholders (a "secondary offering"), or both, but not in connection with a
registration effected solely to implement an employee benefit plan or a
transaction to which Rule 145 or any other similar rule of the Commission under
the Securities Act is applicable), it agrees to do the following:

                  (a) The Corporation shall promptly give written notice of
registration under this Section 4.1 to the holders of Registrable Securities
then outstanding (the "Holders"), and will use its best efforts to effect the
registration under the Securities Act of all Registrable Securities for which
the Holders may request registration in a writing delivered to the Corporation
within fifteen (15) days after such notice given by the Corporation; provided,
however, that in the case of the registration of Common Stock by the Corporation
in connection with an underwritten public offering, the Corporation shall not be
required to register Registrable Securities of the Holders in excess of the
amount, if any, of Common Stock which the principal underwriter of an
underwritten offering shall reasonably and in good faith agree in writing to
include in such offering.

                  (b) If any Registrable Securities are not to be registered
pursuant to this Section 4.1 because the number of Registrable Securities for
which registration has been requested by the Holders pursuant to paragraph (a)
above exceeds the amount of Common Stock which the principal underwriter of an
underwritten offering shall reasonably and in good faith agree in writing to
include in such offering, the Holders who have requested participation shall be
entitled to participate in such registration and offering 


                                      -3-
<PAGE>   4
proportionately in accordance with the number of shares of Common Stock owned or
obtainable by them upon exercise of rights (including conversion rights) with
respect to other securities (including Preferred Stock) owned by them.

                  (c) If the Corporation includes in a registration under this
Section 4.1 any securities to be offered by it, all expenses of the registration
and offering and the reasonable fees and expenses of not more than one
independent counsel for the Holders shall be borne by the Corporation, except
that the Holders shall bear underwriting commissions attributable to their
Registrable Securities being registered and transfer taxes on shares being sold
by such Holders. If the registration under this Section 4.1 is exclusively a
secondary offering, as defined in this Section 4.1, the Holders shall bear their
proportionate share of the expenses of the registration and offering (provided
all shareholders registering shares thereunder bear their proportionate share of
expenses), except expenses which the Corporation would have incurred whether or
not registration was attempted, including, without limitation, the expense of
preparing normal audited or unaudited financial statements or summaries
consistent with this Agreement or applicable Commission filings.

                  (d) Without in any way limiting the types of registrations to
which this Section 4.1 shall apply, in the event that the Corporation shall
effect a "shelf registration", under Rule 415 promulgated under the Securities
Act, or any other similar rule or regulation ("Rule 415"), the Corporation shall
take all necessary action, including, without limitation, the filing of
post-effective amendments, to permit the Holders to include their shares in such
registration in accordance with all of the terms of this Section 4.1.

                  2 REQUIRED REGISTRATIONS. If on any two (2) occasions at least
one year apart, after September 30, 1997, one or more of the Holders of an
aggregate of 10% or more of the Registrable Securities then outstanding and held
by all Holders, shall notify the Corporation in writing that he or they intend
to offer or cause to be offered for public sale all or any portion of their
Registrable Securities having an offering price of not less than $2,000,000, the
Corporation will notify all of the Holders who would be entitled to notice of a
proposed registration under Section 4.1 of its receipt of such notification from
such Holder or Holders. Upon the written request of any such Holder delivered to
the Corporation within fifteen (15) days after receipt from the Corporation of
such notification, the Corporation will either (i) elect to make a primary
offering in which case the rights of the Holders shall be as set forth in
Section 4.1, except that the Corporation shall not be permitted to limit the
number of shares which may be registered by any Holder, or (ii) use its best
efforts to cause such of the Registrable Securities as may be requested by any
Holders (including the Holders giving the initial notice of intent to register
hereunder) to be registered under the Securities Act in accordance with the
terms of this Section 4.2. All expenses of such registrations and offerings and
the reasonable fees and expenses of not more than one independent counsel for
the Holders shall be borne by the Corporation, except that the Holders shall
bear underwriting commissions attributable to their Registrable Securities being
registered, transfer taxes on shares being sold by such Holders and the expense
of any special audit of the Corporation's financial statements if the notice
requesting registration does not reasonably permit the use of existing or
contemplated audited statements. The Corporation shall not be required to cause
a registration statement requested pursuant to this Section 4.2 to become
effective prior to sixty (60) days following the effective date of a
registration statement initiated by the Corporation, if the request for
registration has been received by the Corporation subsequent to the giving of
written notice by the Corporation, made in good faith, to the Holders of
Registrable Securities to the effect that the Corporation is commencing to
prepare a Corporation-initiated registration statement (other than a
registration effected solely to implement an employee benefit plan or a
transaction to which Rule 145 or any other similar rule of the Commission under
the Securities Act is applicable); provided, however, that the Corporation shall
use its best efforts to achieve such effectiveness 


                                      -4-
<PAGE>   5
promptly following such sixty (60) day period if the request pursuant to this
Section 4.2 has been made prior to the expiration of such sixty (60) day period.
The Corporation may postpone the filing of any registration statement required
hereunder for a reasonable period of time, not to exceed thirty (30) days, if
the Corporation has been advised by legal counsel that such filing would require
the disclosure of a material transaction or other factor and the Corporation
determines reasonably and in good faith that such disclosure would have a
material adverse effect on the Corporation.

                  3 SELECTION OF UNDERWRITER. In the case of any registration
effectuated pursuant to Section 4.1, the Corporation shall have the right to
designate the managing underwriter subject to the approval of a majority of the
Holders who have requested registration, and each Holder whose shares are
registered for sale through such underwriter shall enter into an underwriting
agreement in form and on terms customary for such transactions.

                  4 STAND OFF AGREEMENT. Each Holder of Registrable Securities,
if requested by the Corporation and an underwriter of Common Stock or other
securities of the Corporation, shall agree not to sell or otherwise transfer or
dispose of any Registrable Securities or other securities of the Corporation
held by such Holder for a specified period of time (not to exceed 180 days)
following the effective date of a Registration Statement, provided all persons
holding not less than the number of shares of Common Stock held by such Holder
(including shares of Common Stock issuable upon the conversion of Shares, or
other convertible securities, or upon the exercise of options, warrants or
rights) enter into similar agreements. Such agreements shall be in writing in a
form satisfactory to the Corporation and such underwriter. The Corporation may
impose stop-transfer instructions with respect to the Registrable Securities or
other securities subject to the foregoing restriction until the end of the
standoff period.

                  5 FURTHER OBLIGATIONS OF THE CORPORATION. Whenever under the
preceding sections of this Article 4 the Corporation is required to register
Common Stock, it agrees that it shall also do the following:

                  (a) Use its best efforts diligently to prepare for filing with
the Commission a registration statement and such amendments and supplements to
said registration statement and the prospectus used in connection therewith as
may be necessary to keep said registration statement effective and to comply
with the provisions of the Securities Act with respect to the sale of securities
covered by said registration statement for the period necessary to complete the
proposed public offering (but not in excess of 180 days);

                  (b) Furnish to each selling Holder such copies of each
preliminary and final prospectus and such other documents as such Holder may
reasonably request to facilitate the public offering of his or its Common Stock;

                  (c) In the case of Section 4.1, enter into an underwriting
agreement with provisions reasonably required by the proposed underwriter for
the selling Holders, if any; and

                  (d) Use its best efforts to register or qualify the Common
Stock covered by said registration statement under the securities or "blue-sky"
laws of such jurisdictions as any selling Holder may reasonably request,
provided that the Corporation shall not be required to register in any states
which require it to qualify to do business or subject itself to general service
of process.

                  6 FORM S-3. If the Corporation becomes eligible to use Form
S-3 under the Securities Act or a comparable successor form, the Corporation
shall use its best efforts to continue to qualify at all


                                      -5-
<PAGE>   6
times for registration on Form S-3 or such successor form. At any time and from
time to time after the Corporation becomes eligible to use Form S-3 or such
successor form, the Holders of an aggregate of not less than ten percent (10%)
of Registrable Securities then outstanding and held by the Holders shall have
the right to request and have effected a registration of shares of Registrable
Securities on Form S-3 or such successor form for a public offering of shares of
Registrable Securities having an aggregate proposed offering price of not less
than $2,000,000 (such requests shall be in writing and shall state the number of
shares of Registrable Securities to be disposed of and the intended method of
disposition of such shares by such Holder or Holders). The Corporation shall not
be required to cause a registration statement requested pursuant to this Section
4.6 to become effective prior to ninety (90) days following the effective date
of a registration statement initiated by the Corporation, if the request for
registration has been received by the Corporation subsequent to the giving of
written notice by the Corporation, made in good faith, to the Holders of
Registrable Securities to the effect that the Corporation is commencing to
prepare a Corporation-initiated registration statement (other than a
registration effected solely to implement an employee benefit plan or a
transaction to which Rule 145 or any other similar rule of the Commission under
the Securities Act is applicable); provided, however, that the Corporation shall
use its best efforts to achieve such effectiveness promptly following such
ninety (90) day period if the request pursuant to this Section 4.6 has been made
prior to the expiration of such ninety (90) day period. The Corporation may
postpone the filing of any registration statement required hereunder for a
reasonable period of time, not to exceed sixty (60) days, if the Corporation has
been advised by legal counsel that such filing would require the disclosure of a
material transaction or other factor and the Corporation determines reasonably
and in good faith that such disclosure would have a material adverse effect on
the Corporation. The Corporation shall give notice to all Holders of the receipt
of a request for registration pursuant to this Section 4.6 and shall provide a
reasonable opportunity for such Holders to participate in the registration.
Subject to the foregoing, the Corporation will use its best efforts to effect
promptly the registration of all shares of Common Stock on Form S-3 or such
successor form to the extent requested by the Holder or Holders thereof for
purposes of disposition. If so requested by any Holder in connection with a
registration under this Section 4.6, the Corporation shall take such steps as
are required to register such Holder's Registrable Securities for sale on a
delayed or continuous basis under Rule 415, and to keep such registration
effective until all of such Holder's Registrable Securities registered
thereunder are sold (but not in excess of 365 days). All expenses incurred in
connection with a registration requested pursuant to this Section 4.6,
including, without limitation, all registration, qualification, printing, and
accounting and counsel fees, shall be paid by the Holders participating in such
registration on a pro-rata basis in proportion to such participation.
Notwithstanding the foregoing, the Corporation shall not be required to effect a
registration under this Section 4.6 if, in the opinion of counsel for the
Corporation, which counsel and opinion shall be acceptable to the Holders, such
Holders may then sell all Registrable Securities proposed to be sold in the
manner proposed without registration under the Securities Act.

                  7 INDEMNIFICATION. Incident to any registration statement
referred to in this Article 4, and subject to applicable law, (a) the
Corporation will indemnify each underwriter, each Holder of Registrable
Securities so registered, and each person controlling any of them, against all
claims, losses, damages and liabilities, including legal and other expenses
reasonably incurred in investigating or defending against the same, arising out
of any untrue statement of a material fact contained therein, or any omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, or arising out of any violation by the
Corporation of the Securities Act, any state securities or "blue-sky" laws or
any rule or regulation thereunder in connection with such registration, except
insofar as the same may have been caused by an untrue statement or omission
based upon information furnished in writing to the Corporation by such
underwriter, Holder, or controlling person, respectively, expressly for use
therein, and (b) with respect to such untrue statement or omission in the


                                      -6-
<PAGE>   7
information furnished in writing to the Corporation by such Holder, such Holder
will indemnify the underwriters, the Corporation, its directors and officers,
the other Holders and each person controlling any of them against any losses,
claims, damages, expenses (including legal or other expenses) or liabilities to
which any of them may become subject to the same extent.

                  8 RULE 144 REQUIREMENTS. The Corporation will use its best
efforts to file with the Commission such information as the Commission may
require under the reporting requirements of either Section 13 or Section 15(d)
of the Securities Exchange Act of 1934, as amended, and in such event, the
Corporation shall use its best efforts to take all action as may be required as
a condition to the availability of Rule 144 under the Securities Act (or any
successor exemptive rule hereafter in effect). The Corporation shall furnish to
any Holder of Registrable Securities upon request a written statement executed
by the Corporation as to the steps it has taken to comply with the current
public information requirement of Rule 144 or such successor rule.

                  9 AMENDMENT OR WAIVER OF REGISTRATION RIGHTS. The registration
rights provided for in this Article 4 may not be waived otherwise than by a
written instrument signed by the party so waiving such rights; provided,
however, that changes in or additions to, and any consents required by this
Article 4 may be made, and compliance with any term, covenant, condition or
provision set forth in this Article 4 may be omitted or waived (either generally
or in a particular instance and either retroactively or prospectively) by a
consent or consents in writing signed by Holders holding a majority in interest
of the Registrable Securities held by the Holders and (in the case of any such
change or addition) the Corporation. Any amendment or waiver effected in
accordance with this Section 4.9 shall be binding upon each Holder of
Registrable Securities, each transferee of a Holder under Section 4.10 and the
Corporation.

                  10  TRANSFER OF RIGHTS.

         (a) The rights granted to Apollo under this Agreement may be
transferred by a Holder (a) to another person or entity that is then a
stockholder of the Corporation, (b) to any affiliate of a Holder or to any
person or entity acquiring Registrable Securities representing ownership of, or
the right to acquire at least 500,000 shares of Common Stock (as adjusted for
stock splits, stock dividends, recapitalization or similar events), or (c) to a
shareholder or partner of a Holder who receives Registrable Securities as a
distribution from such Holder. Each such transferee shall be deemed to be a
"Holder" for purposes of this Article 4.

         (b) Any transferee (other than a stockholder who is already a party to
an agreement in form and substance similar to this Agreement) to whom rights
under this Agreement are transferred shall, as a condition to such transfer,
deliver to the Corporation a written instrument by which such transferee
identifies itself, give the Corporation notice of the transfer of such rights,
indication the Registrable Securities owned by it and agrees to be bound by the
obligations imposed upon Apollo under this Agreement.

         (c) A transferee to whom rights are transferred pursuant to this
Section 4.10 may not again transfer such rights to any other person or entity,
other than as provided in this Section 4.10.

                                   ARTICLE 5.

                                  MISCELLANEOUS

                  Section 1 SUCCEEDING SECURITIES. In the event the Common Stock
of the Corporation covered by this Agreement is converted into any other
security of the Corporation or any other corporation, the terms of this
Agreement shall apply with full force and effect to any such other security and
the obligations of the Corporation to effect registration and offer pre-emptive
rights shall include such other filings, qualifications, notices and similar
acts as may be necessary to enable Apollo to realize the benefits of
registration and pre-emptive rights provided by this Agreement.

                  Section 2 CONSENT. Wherever reference is made in this
Agreement to a request or consent of holders of a certain percentage of
Registrable Securities, the determination of such percentage shall include
shares of Common Stock issuable upon conversion or exercise of the Registrable
Securities held by a holder even if such conversion or exercise has not yet been
effected.

                  Section 3 WAIVERS; MODIFICATIONS IN WRITING. No failure or
delay on the part of Apollo, or any holder of rights under this Agreement, in
exercising any right, power, or remedy hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any such right, power or
remedy preclude any other or further exercise thereof or the exercise of any
other right, power or remedy. No amendment, modification, supplement,
termination, consent or waiver of or to any provision of this Agreement, nor
consent to any departure therefrom, shall in any event be effective unless the
same shall be in writing and signed by Apollo and the Corporation. Any waiver of
any provision of this Agreement, and any consent to any departure by the
Corporation from the terms of any provisions of this Agreement, shall be
effective only in the specific instance and for the specific purpose for which
given. No notice to or demand on the Corporation in any case shall entitle the
Corporation to any other or further notice or demand in similar or other
circumstances.

                  Section 4 NOTICES, ETC. All notices, demands, instructions and
other communications required or permitted to be given to or made upon any party

reorganization, moratorium or similar laws generally affecting creditors' rights
and by equitable principles (regardless of whether enforcement is sought in
equity or at law).

                  Section 5.3 Subsidiaries. The Borrower has no Subsidiaries

the execution, delivery and performance by each of the Borrower and each of its
Subsidiaries of this Agreement, the Notes and the other Loan Documents to which
it is a party do not and will not: (i) violate any provision of federal, state
or local law or regulation applicable to the Borrower or any of its
Subsidiaries, the certificate of incorporation or by-laws (or other charter
documents) of the Borrower or any of its Subsidiaries, or any order, judgment or
decree of any court or other agency of government binding on the Borrower or any
of its Subsidiaries; (ii) conflict with, result in a breach of or constitute
(with due notice or lapse of time or both) a default under any material

of any Loan Document do not and will not require any registration with, consent
or approval of, or notice to, or other action with or by, any federal, state,
foreign or other governmental authority or regulatory body or other Person, the
failure to secure any of which could reasonably be expected to, in the absence,
have a material adverse effect on the business, properties, operations or
condition (financial or otherwise) of the Borrower, the Borrower and its
Subsidiaries taken as a whole, the Mortgaged Property or the Collateral.

                  Section 5.6 Lien Priority. After giving effect to the
transactions contemplated by this Agreement, the Liens granted by the Borrower
and its Subsidiaries to the Lender in their assets pursuant to the Collateral

accomplished), first priority Liens, subject only to Permitted Liens.

                  Section 5.7 Changes, etc. Since September 30, 1996, there have
been no material adverse changes in the businesses, properties, operations or
condition (financial or otherwise) of the Borrower or the Borrower and its

each Subsidiary shall have good and marketable title to all of the properties

                  Section 5.9  Litigation; Adverse Facts.

                  (a) There is no action, suit, proceeding or arbitration at law
or in equity or before or by any federal, state or other governmental agency or
instrumentality pending or, to the knowledge of the Borrower, threatened against
the Borrower or any Subsidiary that could result in any adverse change in the
business, properties, operations or condition (financial or otherwise) of the
Borrower or the Borrower and its Subsidiaries taken as a whole or may reasonably
be expected to adversely affect the Borrower's ability to perform its
obligations hereunder, under the Notes or the other Loan Documents. The lawsuit

from executing on any judgement obtained.

                  (b) Neither the Borrower nor any Subsidiary is (i) in

writ, injunction, decree, rule or regulation of any court or federal, state or
other governmental agency or instrumentality, in a manner which could reasonably
be expected to have a material adverse effect on the business, properties,
operations or condition (financial or otherwise) of the Borrower or the Borrower
and its Subsidiaries taken as a whole. There is no action, suit, proceeding or
investigation pending or, to the knowledge of the Borrower, threatened against
the Borrower or any Subsidiary which questions the validity or the
enforceability of this Agreement, the Notes or any of the other Loan Documents.

                  Section 5.10 Capital Stock of the Borrower. As of the

of its Subsidiaries owns or holds licenses in all necessary trademarks, trade
names, patents, patent rights and licenses required to conduct its business and
to operate its properties as now conducted and currently projected and without
known conflict with the rights of others. The consummation of the transactions
contemplated by this Agreement, the Notes and the other Loan Documents will not
alter or impair any of such rights of the Borrower or any Subsidiary of the
Borrower except to the extent contemplated by the Loan Documents. Neither the
Borrower or any of its Subsidiaries has been charged, or received a written
threat to be charged, with any infringement of, nor has the Borrower or any of
its Subsidiaries knowingly infringed on any unexpired trademark, trademark
registration, patent or other proprietary right of any Person.

Borrower is in default under any mortgage, indenture, deed of trust or other
agreement to which it is a party or by which it or any of the properties owned
by it are bound, the effect of which could reasonably be expected to have a
material adverse effect on the business, properties, operations or conditions
(financial or otherwise) of the Borrower or the Borrower and its Subsidiaries
taken as a whole.

                  Section 5.14 Leases. The Borrower and each Subsidiary of the

and subsisting and no default by the Borrower or any Subsidiary of the Borrower
exists under any of them.

                  Section 5.15 Burdensome Agreements, etc. Neither the Borrower
nor any Subsidiary of the Borrower is a party to any unusual or unduly
burdensome agreement or undertaking, or subject to any unusual or unduly
burdensome court order, writ, injunction or decree of any court or governmental
agency or instrumentality, which could have a material adverse effect on the
business, properties, operations or condition (financial or otherwise) of the
Borrower or the Borrower and its Subsidiaries taken as a whole.

faith and for which adequate reserves have been provided in accordance with
GAAP.

in or to any of the Mortgaged Property or Collateral until after the Loans have
been indefeasibly paid in full.

                  Section 5.19 Publicly Filed Documents and Financial
Statements.

                  (a) The Borrower has previously furnished or made available to
the Lender true and complete copies of (i) its Annual Reports on Form 10-K for
each of the three fiscal years ended December 31, 1995, 1994 and 1993, as each
such Annual Report has been amended through the date hereof, and as each was
filed with the United States Securities and Exchange Commission (the "SEC");
(ii) its Quarterly Reports on Form 10-Q for each of the quarterly periods ended
June 30, 1996, and March 31, 1996, as each such quarterly report has been
amended through the date hereof, and as each was filed with the SEC; (iii) its
proxy statements relating to all meetings of its stockholders (whether annual or

been amended through the date hereof (collectively, the "Borrower Publicly Filed
Documents"). None of the Borrower Publicly Filed Documents, and including,
without limitation, any financial statements or schedules included in any
Borrower Publicly Filed Documents, at the time filed contained any untrue
statement of material fact or omitted to state a material fact required to be
stated therein or necessary to make the statements therein, in light of any
circumstances under which they were made, not misleading, which untrue
statements or omissions have not been corrected or updated in a document
subsequently filed with the SEC. The financial statements contained in the
Borrower Publicly Filed Documents (the "Financial Statements") comply as to form
in all material respects with applicable accounting requirements and with the
published rules and regulations of the SEC with respect thereto, have been
prepared in accordance with GAAP applicable to year-end financial statements
(except, in the case of unaudited interim financial statements, for the absence
of footnotes and normal year-end adjustments) consistently applied during the
periods involved, and present fairly the consolidated financial condition and
results of operations and cash flow of the Borrower and its Subsidiaries as of
such dates and for such periods. There is no material liability or obligation of
any kind, whether accrued, absolute, fixed or contingent, of the Borrower or any
Subsidiary of the Borrower that is required to be disclosed under GAAP and that
is not reflected or reserved against in the unaudited consolidated balance sheet
of the Borrower as of June 30, 1996 contained in the Borrower's quarterly report
on Form 10-Q for the quarterly period ended June 30, 1996 or reflected in the
notes thereto, other than liabilities incurred in the ordinary course of
business, consistent with past practice, since June 30, 1996, none of which has
had or could



                                      -14-
<PAGE>   19
reasonably be expected to have a material adverse effect on the financial

Subsidiaries taken as a whole.

                  Section 5.20 Use of Proceeds. The Proceeds of the Loans shall

portion thereof) terminated and (ii) the principal of and any accrued interest
in respect of all Loans and all obligations owing hereunder to be, whereupon the
same shall become, forthwith due and payable without presentment, demand,
protest or other notice of any kind, all of which are hereby waived by the
Borrower.

                  Notwithstanding the foregoing, if, at any time after
acceleration of the maturity of the Notes, the Borrower shall pay all arrears of
interest and all payments on account of principal that shall have become due
other than by acceleration (with interest on principal at the rate specified
herein) and all Events of Default and Unmatured Events of Default (other than
nonpayment of principal and accrued interest under the Notes, due and payable
solely by virtue of acceleration) have been remedied or waived, then (i) at the
Lender's option, by written notice to the Borrower, the Lender may rescind and
annul the acceleration and its consequences and (ii) if the Borrower makes such
payment within 30 days after acceleration of the maturity of the Notes, such
acceleration shall be automatically rescinded and annulled without any further
action by any party, except to the extent action by the Borrower or the Lender
is required to effectuate such rescission and annulment, in which case the
parties agree to promptly take such action; provided, however, that such action
shall not affect any subsequent Event of Default or Unmatured Event of Default
or impair any right consequent thereon.

                  Upon acceleration, the Lender, without notice to or demand
upon the Borrower, which are expressly waived by the Borrower, may proceed to
protect, exercise and enforce its rights and remedies hereunder, under the Notes
and under the Collateral Documents, and any other rights and remedies as are
provided by law or equity. The Lender may determine, in its sole discretion, the
order and manner in which the Lender's rights and remedies are to be exercised,
and all payments received by the Lender shall be applied as follows: first, to
all costs and expenses (including, without limitation, reasonable attorneys'
fees and expenses, costs of maintaining, preserving or disposing of any of the
Collateral and costs of settlement) incurred by the Lender in enforcing any Debt
of, or in collecting any payments due from, the Borrower under the Notes by
reason of such Event of Default; second, to accrued interest on the Loans; and
third, to principal amounts outstanding.

                                  MISCELLANEOUS

                  Section 9.1 Waivers; Modifications in Writing. No failure or
delay on the part of the Lender, or any holder of the Notes, in exercising any
right, power, privilege or remedy under this Agreement, the Notes or the other
Loan Documents shall operate as a waiver thereof, nor shall any single or
partial exercise of any such right, power, privilege or remedy preclude any
other or further exercise thereof or the exercise of any other right, power or
remedy. The remedies provided for under this Agreement, in the Notes and in the
other Loan Documents are cumulative and are not exclusive of any remedies that
may be available to the Lender at law, in equity or otherwise. No amendment,
modification, supplement, termination, consent or waiver of or to any provision
of this Agreement, the Notes and the other Loan Documents, nor consent to any
departure therefrom, shall in any event be effective unless the same shall be in
writing and signed by the Lender and the Borrower. Any waiver of any provision
of this Agreement, the Notes and the other Loan Documents, and any consent to
any departure by the Borrower from the terms of any provisions of this
Agreement, shall be effective only in the specific instance and for the specific
purpose for which given. No notice to or demand on the Borrower in any case
shall entitle the Borrower to any other or further notice or demand in similar
or other circumstances.

                  Section 9.2 Effectiveness. This Agreement shall become
effective on the date (the "Effective Date") on which the Borrower and the
Lender shall have signed a counterpart hereof (whether the same or different
counterparts).

and other communications required or permitted to be given to or made upon any
party hereto shall be in writing delivered to the parties at the addresses set

Persons. In the case of any participation, the participant shall not have any

execution of an assignment and assumption agreement between the Lender and such

Documents shall be deemed to have been made in the State of New York and the
validity of this Agreement, the Notes and the other Loan Documents, the
construction, interpretation, and enforcement thereof, and the rights of the
parties thereto shall be determined under, governed by, and construed in
accordance with the internal laws of the State of New York, without regard to
principles of conflicts of law.

                  Section 9.8 Waiver of Jury Trial. Borrower hereby waives all
right to trial by jury in any action, proceeding or counterclaim arising out of
or relating to this Loan Agreement, the Notes, any Loan Document, or any other
agreement or instrument contemplated hereby.

                  Section 9.9 Severability of Provisions. Whenever possible this
Agreement, the Notes and each Loan Document and each provision hereof and
thereof shall be interpreted in such manner as to be effective, valid and
enforceable under applicable law. If and to the extent that any such provision
shall be held invalid and unenforceable by any court of competent jurisdiction,
such holding shall not invalidate or render unenforceable any other provisions
hereof or thereof, and any determination that the application of any provision
hereof or thereof to any person or under any circumstance is illegal and
unenforceable shall not affect the legality, validity and enforceability of such
provision as it may be applied to any other person or in any other circumstance.

this Agreement shall each be given independent effect so that if a particular
action or condition is not permitted by any such covenant, the fact that it
would be permitted by another covenant, by an exception thereto, or be otherwise

exists.

                                PLEDGE AGREEMENT


                  PLEDGE AGREEMENT, dated as of November 14, 1996 (this
"Agreement"), among each of the undersigned (each a "Pledgor" and, collectively,
the "Pledgors") and AP LOM LLC ("Pledgee").

                              W I T N E S S E T H:

                  WHEREAS, NextHealth, Inc. (the "Borrower") and Pledgee have
entered into a Credit Agreement, dated as of November 14, 1996 (as amended,
modified or supplemented from time to time, the "Credit Agreement"), pursuant to
which Pledgee has agreed to make certain Loans to the Borrower;

                  WHEREAS, pursuant to the Guaranty, each Pledgor (other than
the Borrower) has jointly and severally guaranteed to the Pledgee the payment
when due of all obligations and liabilities of the Borrower under or with
respect to the Credit Agreement;

                  WHEREAS, it is a condition precedent to the making of Loans to
the Borrower under the Credit Agreement that each Pledgor shall have executed
and delivered to the Pledgee this Agreement; and

                  WHEREAS, each Pledgor desires to execute this Agreement to
satisfy the condition precedent described in the preceding paragraph;

                  NOW, THEREFORE, in consideration of the benefits accruing to
each Pledgor, the receipt and sufficiency of which are hereby acknowledged, each
Pledgor makes the following representations and warranties to the Pledgee and
hereby covenants and agrees with the Pledgee as follows:

                  1. Definitions. Unless otherwise defined herein, capitalized
terms used herein shall have the meaning ascribed to such terms in the Credit
Agreement. References to this "Agreement" shall mean this Pledge Agreement as
the same may be in effect at the time such reference becomes operative,
including all amendments, modifications and supplements hereto and any exhibits
or schedules to any of the foregoing.

                  2. Pledge. In order to secure the full and prompt payment when
due (whether at stated maturity, by acceleration or otherwise) of all
obligations and liabilities of such Pledgor, now existing or hereafter incurred
under, arising out of or in connection with any Loan Document to which it is a
party and the due performance and compliance by such Pledgor with the terms of
each such Loan Document (the "Obligations"), each Pledgor hereby pledges,
assigns, grants a security interest in, transfers and delivers unto Pledgee each
of the following (the "Collateral"):

                  (a) all of such Pledgor's right, title and interest in and to
all shares (the "Pledged Shares") of capital stock described in Schedule I
hereto and the certificates, if any, representing the Pledged Shares, and all
dividends, cash, instruments and other property from time to time received,
receivable or otherwise distributed in respect of or in exchange for any or all
of the Pledged Shares;

                  (b) all additional shares (the "Additional Shares") of capital
stock at any time or from time to time acquired by such Pledgor in any manner
(including, without limitation, any shares of preferred stock and the
certificates, if any, representing such Additional Shares), and all dividends,
cash, instruments and other property from time to time received, receivable or
otherwise distributed in respect of or in exchange for any or all of such
shares;
<PAGE>   2
                  (c) all other rights appurtenant to the property described in
clauses (a) and (b) above (including, without limitation, voting rights); and

                  (d) all cash and noncash proceeds of any and all of the
foregoing.

Certificates representing the Pledged Shares set forth on Schedule I hereto,
accompanied by proper instruments of assignment duly executed in blank by each
Pledgor, are herewith delivered to Pledgee. Promptly upon each Pledgor's
acquisition of any Additional Shares, such Pledgor will (i) deliver proper
instruments of assignment duly executed in blank by such Pledgor together with
any certificates representing such Additional Shares, whereupon such Additional
Shares shall be Pledged Shares; and (ii) amend Schedule I to include such
Additional Shares.

                  3. Representations and Warranties. Each Pledgor hereby
represents and warrants to Pledgee that as of the date hereof, and agrees that
each delivery of Additional Shares shall constitute a representation and
warranty that as of the date thereof:

                  (a) Such Pledgor is the sole holder of record and beneficial
owner of the Pledged Shares set forth on Schedule I hereto, free and clear of
any pledge, hypothecation, assignment, lien, charge, claim, security interest,
option, preference, priority or other preferential arrangement of any kind or
nature whatsoever ("Lien") thereon or affecting the title thereto.

                  (b) The Pledged Shares have been duly authorized and validly
issued by each of the respective issuers set forth in Schedule I, and are fully
paid and non-assessable, and such Pledgor has the right and all requisite
corporate authority to pledge, assign, grant a security interest in, transfer
and deliver the Collateral to Pledgee as provided herein.

                  (c) This Agreement has been duly authorized, executed and
delivered by such Pledgor and constitutes the legal, valid and binding
obligation of such Pledgor, enforceable in accordance with its terms, subject to
applicable bankruptcy, insolvency and similar laws affecting creditors' rights
generally and subject, as to enforceability, to general principles of equity.

                  (d) No consent, approval, authorization or other order of any
Person is required for (i) the execution and delivery of this Agreement or the
delivery of the Collateral to Pledgee as provided herein, or (ii) for the
exercise by Pledgee of the voting or other rights provided for in this Agreement
or the remedies in respect of the Collateral pursuant to this Agreement, except
as may be required in connection with the disposition of the Collateral by laws
affecting the offering and sale of securities generally.

                  (e) The chief executive office of such Pledgor is set forth
opposite its signature below. Such Pledgor has no trade name.

                  (f) Upon the delivery to Pledgee of the certificates
representing the Pledges Shares, Pledgee will have a valid and perfected first
priority security interest therein subject to no prior Lien.

                  The representations and warranties set forth in this Section 3
shall survive the execution and delivery of this Agreement.

                  4. Rights of Pledgors. Unless an Event of Default shall have
occurred and be continuing:

                  (a) Each Pledgor shall be entitled to exercise any and all
voting and other consensual rights pertaining to the Pledged Shares or any part
thereof for any purpose not inconsistent with the terms of this Agreement or the
Credit Agreement; provided, that such Pledgor shall not exercise or refrain from
exercising such right if, in such Pledgee's judgment, such action could
reasonably be expected to have a material adverse effect on the value of the
Pledged Shares or any part thereof, and provided, further, that such Pledgor
shall give Pledgee at


                                      -2-
<PAGE>   3
least five days' prior written notice of the manner in which it intends to
exercise, or the reasons for refraining from exercising, any such right.

                  (b) Each Pledgor shall be entitled, from time to time, to
collect and receive for its own use all cash dividends (except cash dividends
paid or payable in respect of the total or partial liquidation of an issuer or
such other distribution in return of capital) paid on the Pledged Shares;
provided, however, that until actually paid, all rights to such dividends shall
remain subject to the Lien of this Agreement. All dividends (other than cash
dividends governed by the immediately preceding sentence) and all other
distributions in respect of any of the Collateral, whenever paid or made, shall
be delivered to Pledgee and held by it subject to the Lien created by this
Agreement.

                  5. Covenants. Each Pledgor covenants and agrees that until the
termination of this Agreement:

                  (a) Such Pledgor will not, without the prior written consent
of Pledgee, sell, assign, transfer, mortgage, pledge or otherwise encumber any
of its rights in or to the Collateral or any dividends or other distributions or
payments with respect thereto or grant a Lien on any thereof.

                  (b) Such Pledgor will, at its own expense, execute,
acknowledge and deliver all such instruments and take all such action as Pledgee
from time to time may reasonably request in order to ensure to Pledgee the
benefits of the first priority Lien on and to the Collateral intended to be
created by this Agreement.

                  (c) Such Pledgor will defend the title to the Collateral and
the Lien of Pledgee thereon against the claim of any Person claiming against or
through such Pledgor and will maintain and preserve such Lien so long as this
Agreement shall remain in effect.

                  (d) Unless such Pledgor shall have given Pledgee not less than
30 days' prior notice thereof, such Pledgor will not change (i) its name,
identity or corporate structure in any manner or (ii) the location of its chief
executive office.

                  6.       Remedies.

                  (a) Upon the occurrence of an Event of Default, then or at any
time during the continuance of such occurrence, Pledgee is hereby authorized and
empowered, at its election, (i) to transfer and register in its or its nominee's
name the whole or any part of the Collateral, (ii) to exercise all voting rights
with respect thereto, (iii) to demand, sue for, collect, receive and give
acquittance for any and all cash dividends or other distributions or monies due
or to become due upon or by virtue thereof, and to settle prosecute or defend
any action or proceeding with respect thereto, (iv) to sell in one or more sales
the whole or any part of the Collateral or otherwise to transfer or assign the
same, applying the proceeds therefrom to the payment of the Obligations in such
order as Pledgee shall determine, and (v) otherwise to act with respect to the
Collateral or the proceeds thereof as though Pledgee were the outright owner
thereof, each Pledgor hereby irrevocably constituting Pledgee as its proxy and
attorney-in-fact, with full power of substitution to do so.

                  (b) Pledgee shall give each Pledgor not less than ten days'
prior written notice of the time and place of any sale or other intended
disposition of any of the Collateral except any Collateral that is perishable or
threatens to decline speedily in value or is of a type customarily sold on a
recognized market. Such Pledgor agrees that such notice constitutes "reasonable
notification" within the meaning of Section 9-504(3) of the Uniform Commercial
Code. Any sale shall be made at a public or private sale at Pledgee's place of
business, or at any public building in The City of New York to be named in the
notice of sale, either for cash or upon credit or for future delivery at such
price as Pledgee may deem fair, and, to the extent permitted by applicable law,
Pledgee may be the purchaser of the whole or any part of the Collateral so sold
and hold the same thereafter in its own right free from any claim of such
Pledgor or any right or equity of redemption, which right or equity is hereby
waived and released. Each sale shall be made to the highest bidder, but Pledgee
reserves the right to reject any and all bids at such sale which, in its sole
discretion, it shall deem inadequate. Except as otherwise herein specifically
provided for, demands 


                                      -3-
<PAGE>   4
of performance, notices of sale, advertisements and the presence of property at
sale are hereby waived and any sale hereunder may be conducted by an auctioneer
or any officer of agent of Pledgee.

                  (c) If, at the original time or times appointed for the sale
of the whole or any part of the Collateral, either (i) the highest bid, if there
be but one sale, shall be inadequate to discharge in full all the Obligations,
or (ii) if the Collateral be offered for sale in lots, if at any of such sales
the highest bid for the lot offered for sale would indicate to Pledgee in its
sole discretion the unlikelihood of the proceeds of the sales of the whole of
the Collateral being sufficient to discharge all the Obligations, then in either
such event Pledgee may, on one or more occasions, postpone any of said sales by
public announcement at the time of sale. In the event of any such postponement,
Pledgee shall give such Pledgor notice of such postponement.

                  (d) If, following an Event of Default, Pledgee, in its sole
discretion, determines that it is necessary or advisable to effect a public
registration of all or part of the Collateral pursuant to the Securities Act of
1933, as amended (the "Act"), then each Pledgor shall use its best efforts to
cause the issuer or issuers of the Pledged Shares contemplated to be sold, to
execute and deliver, and cause the directors and officers of such issuer to
execute and deliver, all at such Pledgor's expense, all such instruments and
documents, and to do or cause to be done all such other acts and things as may
be necessary or, in the reasonable judgment of Pledgee, advisable to register
such shares under the provisions of the Act and to cause the registration
statement relating thereto to become effective and to remain effective for a
period of 9 months from the initial effective date thereof, and to make all
amendments thereto or to the related prospectus or both that, in the reasonable
judgment of Pledgee, are necessary or advisable, all in conformity with the
requirements of the Act and the rules and regulations promulgated thereunder.
Such Pledgor agrees to use its best efforts to cause such issuer or issuers to
(i) comply with the provisions of the securities or "Blue Sky" laws of any
jurisdiction designated by Pledgee and (ii) make available to its security
holders, as soon as practicable, an earnings statement that will satisfy the
provisions of Section 11(a) of the Act.

                  (e) All expenses incurred in complying with Section 6(d),
including, without limitation, all registration and filing fees (including all
expenses incident to filing with the National Association of Securities Dealers,
Inc.), printing expenses, fees and disbursements of counsel for each Pledgor or
for the issuers of the Pledged Shares, the reasonable fees and expenses of
counsel for Pledgee, expenses of any special audits incident to or required by
any such registration and expenses of complying with the securities or blue sky
laws or any jurisdictions, shall be paid by such Pledgor.

                  (f) If, at any time when Pledgee shall determine to exercise
its right to sell the whole or any part of the Collateral hereunder, such
Collateral or the part thereof to be sold shall not, for any reason whatsoever,
be effectively registered under the Act, Pledgee may, in its sole and absolute
discretion (subject only to applicable requirements of law), sell such
Collateral or part thereof by private sale in such manner and under such
circumstances as Pledgee may deem necessary or advisable, but subject to the
other requirements of this Section 6, and shall not be required to effect such
registration or to cause the same to be effected. Without limiting the
generality of the foregoing, in any such event Pledgee in its sole and absolute
discretion may (a) proceed to make such private sale notwithstanding that a
registration statement for the purpose of registering such Collateral or part
thereof could be or shall have been filed under the Act (or similar statute),
(b) approach and negotiate with a single possible purchaser to effect such sale,
(c) restrict such sale to a purchaser who will represent and agree that such
purchaser is purchasing for its own account, for investment and not with a view
to the distribution or sale of such Collateral or part thereof, and (d) require
that any sale hereunder (including a sale at auction) be conducted subject to
restrictions (i) as to the financial sophistication and ability of any Person
permitted to bid or purchase at sale, (ii) as to the content of legends to be
placed upon any certificates representing the Collateral sold in such sale,
including restrictions on fixture transfer thereof, (iii) as to the
representations required to be made by each Person bidding or purchasing at such
sale relating to that Person's access to financial information about the
relevant Pledgor, any of the issuers of the Pledged Shares or Pledgee, such
Person's intentions as to the holding of the Collateral so sold for investment,
for its own account, and not with a view to the distribution thereof, and (iv)
as to such other matters as Pledgee may, in its sole discretion, deem necessary
or appropriate in order that such sale (notwithstanding any failure so to
register) may be effected in compliance with the Uniform Commercial Code and
other laws affecting the enforcement of creditors' rights and the Act (or
similar statute) and all applicable state securities laws. Each Pledgor

                                      -4-
<PAGE>   5
will execute and deliver such documents and take such other action as Pledgee
deems necessary or advisable in order that any such sale may be made in
compliance with law.

                  (g) Each Pledgor acknowledges that: (i) any sale under the
circumstances described in this Section 6 shall be deemed to have been held in a
manner which is commercially reasonable, and (ii) notwithstanding the legal
availability of a private sale or a sale subject to restrictions of the
character described above, Pledgee may, in its sole discretion, elect to seek
registration of the Collateral under the Act (or similar statute or any
applicable state securities laws) in accordance with its rights under this
Section 6. In the event of any such sale under the circumstances described in
this Section 6, Pledgee shall incur no responsibility or liability for selling
the whole or any part of the Collateral at a price which Pledgee may deem
reasonable under the circumstances, notwithstanding the possibility that a
substantially higher price might be realized if the sales were deferred until
after registration as aforesaid. Each Pledgor hereby further acknowledges that
any sale of any of the Collateral which has not been registered under the Act
may be for a price less that which might have been obtained had the Collateral
been registered under the Act.

                  (h) Each Pledgor agrees that it will not at any time plead,
claim or take the benefit of any appraisal, valuation, stay, extension,
moratorium or redemption law now or hereafter in force in order to prevent or
delay the enforcement of this Agreement, or the absolute sale of the whole or
any part of the Collateral or the possession thereof by any purchaser at any
sale hereunder, and each Pledgor waives the benefit of all such laws to the
extent it lawfully may do so. Each Pledgor agrees that it will not interfere
with any right, power and remedy of Pledgee provided for in this Agreement or
now or hereafter existing at law or in equity or by statute or otherwise, or the
exercise or beginning of the exercise by Pledgee of any one or more such rights,
powers or remedies. No failure or delay on the part of Pledgee to exercise any
such right, power or remedy, and no notice or demand which may be given to or
made upon any Pledgor by Pledgee with respect to any such remedies, shall
operate as a waiver thereof, or limit or impair Pledgee's right to take any
action or to exercise any power or remedy hereunder without notice or demand, or
prejudice its rights as against such Pledgor in any respect.

                  (i) Each Pledgor jointly and severally agrees to indemnify and
hold harmless Pledgee and each Person who controls Pledgee within the meaning of
either the Act or the Securities Exchange Act of 1934, as amended (the "Exchange
Act") against any and all losses, claims, damages or liabilities, joint or
several, to which Pledgee or such Person may become subject under the Act, the
Exchange Act or other Federal or state statutory law or regulation, at common
law or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon any untrue statement
or alleged untrue statement of a material fact contained in the registration
statement for the registration of the Collateral as originally filed or in any
amendment thereof, or in any preliminary prospectus or the prospectus, or in any
amendment thereof or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
agrees to reimburse each such indemnified party for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that no
Pledgor will be liable in any such case to the extent that any such loss, claim,
damage or liability arises out of or is based upon any such untrue statement or
alleged untrue statement or omission or alleged omission made therein in
reliance upon and in conformity with written information furnished to such
Pledgor by or on behalf of Pledgee specifically for use in connection with the
preparation thereof.

                  7. Exoneration of Pledgee. Other than the exercise of
reasonable care in the custody and preservation of the Collateral, Pledgee shall
have no duty with respect thereto. Pledgee shall be deemed to have exercised
reasonable care in the custody and preservation of the Collateral in its
possession if the Collateral is accorded treatment substantially equal to that
which it accords its own property, and shall not be liable or responsible for
any loss or damage to any of the Collateral, or for any diminution in the value
thereof, by reason of the act or omission of any agent or bailee selected by
Pledgee in good faith.

                  8. Waiver. No delay on Pledgee's part in exercising any power
of sale or other right hereunder, and no notice or demand which may be given to
or made upon any Pledgor by Pledgee with respect to 


                                      -5-
<PAGE>   6
any power of sale or other right hereunder, shall constitute a waiver thereof,
or limit or impair Pledgee's right to take any action or to exercise any power
of sale or any other right hereunder, without notice or demand, or prejudice
Pledgee's rights as against such Pledgor in any respect.

                  9. Assignment. Neither party may assign its rights under this
agreement, except that in the event of assignment by Pledgee of its rights under
the Credit Agreement in accordance therewith, the party to whom such assignment
is made shall be entitled to Pledgee's rights hereunder.

                  10. Termination. At such time as (a) all Obligations have been
fully satisfied and no Note is outstanding and (b) the Credit Agreement shall
have been terminated, Pledgee shall deliver to such Pledgor the Collateral at
the time subject to this Agreement and all instruments of assignment executed in
connection therewith, free and clear of the Lien hereof and all of such
Pledgor's obligations hereunder shall thereupon terminate. When so released,
such Collateral shall be free and clear of any lien or encumbrance hereunder.

                  11. Release. Each Pledgor consents and agrees that Pledgee may
at any time, or from time to time, in Pledgee's sole discretion, exchange,
release and/or surrender all or any of the Collateral, or any part(s) thereof,
by whomever deposited, which is now or may hereafter be held by Pledgee in
connection with all or any of the Obligations; all in such manner and upon such
terms as Pledgee may deem proper, and without notice to or further assent from
such Pledgor, it being hereby agreed that such Pledgor shall be and remain bound
by this Agreement, irrespective of the existence, value or condition of any
collateral and notwithstanding (i) any such exchange, release and/or surrender
and/or (ii) any settlement, compromise, surrender, release, renewal or extension
of any or all of the Obligations, and/or (iii) that the Obligations may at any
time or from time to time exceed the aggregate principal amount outstanding
pursuant to the Credit Agreement.

                  12. Expenses. Each Pledgor jointly and severally agrees to
reimburse Pledgee for all expenses (including reasonable expenses for legal
services of every kind) of, or incidental to the preparation or enforcement of
any of the provisions of, this Agreement or any actual or attempted sale, or any
exchange, enforcement, collection, compromise or settlement of any of the
Collateral and for the care of the Collateral and defending or asserting the
rights and claims of Pledgee in respect of the Collateral, by litigation or
otherwise, including but not limited to expenses of insurance and the fees and
expenses of counsel for Pledgee. All such expenses shall be deemed additional
Obligations.

                  13.      Miscellaneous.

                  (a) Pledgee may execute any of its duties hereunder by or
through agents or employees. Pledgee may consult with legal counsel and any
action taken or suffered in good faith in accordance with the advice of such
counsel shall be fall justification and protection to it.

                  (b) Neither Pledgee nor any of its officers, directors,
employees, agents or counsel shall be liable for any action lawfully taken or
omitted to be taken by it or them hereunder or in connection herewith, except
for their own gross negligence or willful misconduct and Pledgee shall not be
liable for any error of judgment made by it in good faith.

                  (c) This Agreement shall be binding upon each Pledgor and its
successors and assigns, and shall inure to the benefit of, and be enforceable
by, Pledgee and its successors, transferees and assigns. None of the terms or
provisions of this Agreement may be waived, altered, modified or amended except
in writing duly signed for and on behalf of Pledgee and each Pledgor directly
affected thereby.

                  (d) THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO
CONTRACTS MADE AND PERFORMED IN SUCH STATE.

<PAGE>   7
                  (e) Each Pledgor hereby consents to the jurisdiction of any
state or federal court located within New York County, New York, and waives
personal service or any and all process upon such Pledgor, and consents that all
such service of process be made by registered mail directed to such Pledgor at
the address stated in section 15 hereof and service so made shall be deemed to
be completed five (5) Business Days after the same shall have been deposited in
the United States mails, postage prepaid.

To the extent permitted by law, each Pledgor waives trial by jury and waives any
objection to venue of any action instituted hereunder.

                  14.      Further Assurances, Pledgee May Perform.

                  (a) At each Pledgor's expense, such Pledgor will do all such
acts, and will furnish to Pledgee all such financing statements, certificates,
legal opinions and other documents and will do or cause to be done all such
other things as Pledgee may reasonably request from time to time in order to
give full effect to this Agreement and to secure the rights intended to be
granted to Pledgee hereunder. To the extent permitted by applicable law, each
Pledgor hereby authorizes Pledgee to execute and file, in the name of such
Pledgor or otherwise, Uniform Commercial Code financing statements (which may be
photocopies of this Agreement) which Pledgee in its sole discretion may deem
necessary or appropriate.

                  (b) If any Pledgor fails to perform any act required by this
Agreement, Pledgee may perform, or cause performance of, such act, and the
expenses of Pledgee incurred in connection therewith shall be governed by
Section 12 hereof.

                  15. Notices. Except as otherwise provided herein, any notice
required hereunder shall be in writing, and shall be deemed to have been validly

Express or similar service, or five business days after deposit in the United
States mails, registered first class mail, with proper postage prepaid, and
addressed to the party to be notified at the following addresses (or such other
