         3.1      Agreement to Transfer Initial Projects. During January of 
1999, each of HCR and ALS shall provide DEVCO with a Proposal with respect to,
and an opportunity to review, all Proposed Projects of such Party and its
Controlled Affiliates at such time. Such Party (the "Offering Party") shall

selected by DEVCO from Proposed Projects offered in January of 1999 shall not
exceed (i) One Hundred Twenty-Five Million Dollars ($125,000,000) with respect
to Proposed Projects offered by ALS and (ii) One Hundred Twenty-Five Million
Dollars ($125,000,000) with respect to Proposed Projects offered by HCR. If,
after taking into account the Proposed Projects accepted by DEVCO, the
aggregate estimated Project Costs to be contributed by one party exceeds the
aggregate estimated Project Costs of the Proposed Projects to be contributed by
the other Party by more than Ten Million Dollars ($10,000,000), then the
Parties shall agree to either add additional Proposed Projects or to remove
Proposed Projects to reduce the difference to the extent economically feasible.
Subject to the terms and conditions hereof, each of HCR and ALS hereby agree to
cause each of their respective Controlled Affiliates who are Project
Transferors with respect to any of the Proposed Projects (i) to enter into a
Project Purchase Agreement with the Acquiring Entity designated by DEVCO with
respect to such Initial Project promptly following DEVCO's request with respect
thereto and (ii) to transfer, convey and assign such Initial Project to such
Acquiring Entity pursuant to the terms of such Project Purchase Agreement at
the Initial Closing. In the event that the Initial Closing with respect to any
Initial Project proposed by ALS does not occur on or before March 31, 1999, ALS
shall have the right to substitute such Initial Project with another Project.
If ALS elects to make any substitutions, ALS shall notify HCR of each Initial
Project that it elects to substitute (each a "Removed Project") and shall
provide HCR with a Proposal for another Project (each a "Substitute Project")
to replace the Removed Project. HCR shall have the right to reject a Substitute
Project within fifteen (15) days after receipt of the Proposal relating
thereto. If any Substitute Project is rejected then ALS shall be entitled to
withdraw the Removed Project as an Initial Project and ALS's 2000 Contribution
shall be increased by an amount equal to the estimated Project Cost of the
Removed Project (each an "ALS Initial Adjustment"). If a Substitute Project is
not rejected (i) the Acquiring Entity designated by DEVCO shall promptly enter
into a Project Purchase Agreement with the Project Transferor of the Substitute
Project and (ii) the Project Transferor shall transfer, convey and assign such
Substitute Project to such Acquiring Entity pursuant to the terms of such
Project Purchase Agreement. If DEVCO selects an Initial Project (including any
Substitute Project) from HCR or ALS pursuant to the provisions hereof and
within 180 days thereafter DEVCO determines that such Initial Project is not
feasible, then the HCR 2000 Contribution or the ALS 2000 Contribution, as
applicable, shall be increased by the estimated Project Cost attributable to
such Initial Project. The purchase consideration payable to each Project
Transferor pursuant to any Project Purchase Agreement shall be, in each case,
in an amount equal to such Project Transferor's Project Costs incurred through
the date of transfer with respect to such Project as certified by the Project
Transferor and shall be subject to approval, not to be unreasonably withheld,
of (i) HCR with respect to Initial Projects to be transferred from Project
Transferors who are ALS Affiliates and (ii) ALS with respect to Initial
Projects to be transferred from Project Transferors who are HCR Affiliates. Any
Proposed Project not accepted by DEVCO within the time periods provided herein,
shall be deemed rejected 



                                       9

and DEVCO shall have no further rights hereunder with respect to such Proposed
Project and, among other things, the Offering Party and its respective
Affiliates shall be entitled to construct, develop, own, operate and/or sell
such Proposed Project in such manner as it may determine in its sole discretion
without any restriction hereunder; provided, however, that if all permits
necessary to complete construction of the Proposed Project have not been issued
within 12 months after the end of the DEVCO review period with respect to such
Proposed Project, then such Proposed Project shall again be subject to the
terms hereof.

         3.2      Designation of Acquiring Entity. The determination of DEVCO
with respect to which Proposed Projects shall become Initial Projects shall be
made by the Board of Managers; provided, however, that, in the event a Proposed
Project is not approved as an Initial Project by a majority of the members of
the Board of Managers, but such Proposed Project is approved as an Initial
Project by the unanimous approval of each of the Members of the Board of
Managers designated by the Party not affiliated with the Offering Party, then
such Proposed Project shall be deemed approved as Initial Project. DEVCO shall
give written notice to the Offering Party during the Initial Period (or in the
case of any Substitute Project within fifteen (15) days after receipt of the
Proposal relating thereto) which notice shall designate the Proposed Projects
selected by DEVCO to be Initial Projects. Prior to the Initial Closings, and in
any event on or before March 15, 1999, DEVCO shall notify the Parties of its
determination with respect to each of the Initial Projects of the specific
DEVCO Entity that is to be the Acquiring Entity of such Initial Project, such
determination to be made based upon the Board of Managers assessment of the
appropriate ownership and operating structure for each such Initial Project in
accordance with the guidelines set forth in Article 7 hereof.

         3.3      Initial Closings. The Parties hereby agree, subject to the
terms and conditions hereof, to cause all of the Initial Projects to be
transferred by their respective Project Transferors thereof to the applicable
Acquiring Entity or Entities thereof at one or more closings to be held at such
times, places and locations agreed to by the parties, but no later than June
30, 1999; provided, however, that no such closing shall occur unless prior to
such time the aggregate consideration paid to HCR at closings held pursuant to
the Agreement of Purchase and Sale (Operating Residences) or the Agreement of
Purchase of and Sale (Construction Residences), each such agreement dated as of
the date of this Agreement and each by and between HCR, ALS and certain
wholly-owned subsidiaries of HCR, shall have exceeded One Hundred Million
Dollars ($100,000,000). To the extent that any Initial Project is acquired by a
Project Entity, the purchase consideration payable to the applicable Project
Transferor shall be paid in the form of a promissory note of such Project
Entity on such terms (including interest rate) as shall be agreed to by the
parties hereto and payable (together with all accrued interest thereof) upon
the first to occur of (i) the 6 month anniversary of such promissory note or
(ii) the date upon which such Project Entity receives the proceeds from any
construction or permanent financing of the applicable Project, whether in the
form of a construction or permanent loan or in the form of a sale/leaseback
transaction, such note, if requested by the Project Transferor, to be secured
by a mortgage or deed of trust



                                       10

on the real property comprising such Project.


                                   ARTICLE 4
                       ACQUISITION OF ADDITIONAL PROJECTS

         4.1      Right of First Offer. During May and November of 1999, each 
of HCR and ALS shall provide DEVCO a Proposal with respect to, and an
opportunity to review, all Proposed Projects of such Party and its Controlled
Affiliates at such time(s). Such Party (the "Offering Party") shall provide
DEVCO with access to all Project Information relating to such Proposed Project.
DEVCO shall have 30 days after it has received such Proposal (the "1999
Proposal Period") in which to identify Proposed Projects which shall become
Additional Projects pursuant to this Agreement; provided, however, that the
aggregate estimated Project Cost for Additional Projects selected by DEVCO from
Proposed Projects offered in May and November of 1999 shall not exceed (i) the
ALS 2000 Contribution with respect to Proposed Projects offered by ALS and (ii)
the HCR 2000 Contribution with respect to Proposed Projects offered by HCR. If
DEVCO selects an Additional Project from HCR or ALS in 1999 and within 180 days
thereafter DEVCO determines that such Additional Project is not feasible, then
the HCR 2001 Contribution or the ALS 2001 Contribution, as applicable, shall be
increased by the estimated Project Cost attributable to such Additional
Project. If in 1999 either HCR or ALS fail to offer to DEVCO Proposed Projects
(other than the Initial Projects) with an aggregate total Project Cost equal to
or greater than the HCR 2000 Contribution or the ALS 2000 Contribution,
respectively, then the amount of any such deficiency shall be added to the HCR
2001 Contribution or the ALS 2001 Contribution, as the case may be.

         During May and November of 2000, each of HCR and ALS shall provide
DEVCO with a Proposal with respect to, and an opportunity to review, all
Proposed Projects of such Party and its Controlled Affiliates at such time(s).
Such Offering Party shall provide DEVCO with access to all Project Information
relating to the Proposed Projects. DEVCO shall have 30 days after it has
received such Proposal (the "2000 Proposal Period") in which to identify
Proposed Projects which shall become Additional Projects pursuant to this
Agreement; provided, however, that the aggregate estimated Project Cost for
Additional Projects selected by DEVCO from Proposed Projects offered in May and
November of 2000 shall not exceed (i) the ALS 2001 Contribution with respect to
Proposed Projects offered by ALS and (ii) the HCR 2001 Contribution with
respect to Proposed Projects offered by HCR. If in 2000 either HCR or ALS fail
to offer to DEVCO Proposed Projects with an aggregate total Project Cost equal
to or greater than the HCR 2001 Contribution or the ALS 2001 Contribution,
respectively, then the amount of any such deficiency shall become the "HCR
Remaining Contribution" or the "ALS Remaining Contribution", as the case may
be. If DEVCO selects an Additional Project from HCR or ALS in 2000 and within
180 days thereafter DEVCO determines that such Additional Project is not
feasible, then the HCR Remaining Contribution or the ALS Remaining
Contribution, as applicable, shall be 



                                      11
<PAGE>   15



increased by the estimated Project Cost attributable to such Additional
Project, unless the estimated Project Costs attributable to Additional Projects
selected by DEVCO prior to January 1, 2001 (exclusive of any such Additional
Project deemed not feasible) equal or exceed the ALS 2001 Contribution or the
HCR 2001 Contribution, as applicable.

         If, after December 31, 2000 there is any ALS Remaining Contribution or
any HCR Remaining Contribution then ALS, HCR or both, as applicable, shall
during May of 2001, provide DEVCO with a Proposal with respect to, and an
opportunity to review, all Proposed Projects of such Party and its Controlled
Affiliates at such time. Such Offering Party shall provide DEVCO with access to
all applicable Project Information. DEVCO shall have 30 days after it has
received such Proposal (the "2001 Proposal Period") in which to identify
Proposed Projects which shall become Additional Projects pursuant to this
Agreement; provided, however, that the aggregate estimated Project Cost for
Additional Projects selected by DEVCO from Proposed Projects offered in May of
2001 shall not exceed (i) the ALS Remaining Contribution with respect to
Proposed Projects offered by ALS and (ii) the HCR Remaining Contribution with
respect to Proposed Projects offered by HCR.

         4.2      Review of Proposed Projects. The determination of DEVCO with
respect to which Proposed Projects shall become Additional Projects shall be
made by the Board of Managers; provided, however, that, in the event a Proposed
Project is not approved as an Additional Project by a majority of the members
of the Board of Managers, but such Proposed Project is approved as an
Additional Project by the unanimous approval of each of the members of the
Board of Managers designated by the Party not affiliated with the Offering
Party, then such Proposed Project shall be deemed approved as an Additional
Project. DEVCO shall give written notice to the Offering Party during the
applicable Proposal Period which notice shall designate the Proposed Projects
selected by DEVCO to be Additional Projects and which notice shall further
designate whether, with respect to each Additional Project, DEVCO or a Project
Entity shall be the Acquiring Party and each such Acquiring Party and the
Offering Party shall promptly (in any event within 30 days after such notice is
given by DEVCO) enter into a Project Purchase Agreement with respect to such
Additional Project. Any Proposed Project not accepted by DEVCO within the
Proposal Period with respect to such Proposed Project, shall be deemed rejected
and DEVCO shall have no further rights hereunder with respect to such Proposed
Project and, among other things, the Offering Party and its respective
Affiliates shall be entitled to construct, develop, own, operate and/or sell
such Proposed Project in such manner as it may determine in its sole discretion
without any restriction hereunder; provided, however, that if all permits
necessary to complete construction of the Proposed Project have not been issued
within 12 months after the end of the Proposal Period, then such Proposed
Project shall again be subject to the terms hereof.

         4.3      Closing of Acquisitions of Additional Projects. The Parties
hereby agree, subject to the terms and conditions hereof, to cause all of the
Additional Projects to be transferred by the respective Project Transferors
thereof to the respective Acquiring Entity or 



                                      12
<PAGE>   16



Entities thereof at closings to be held at such locations as the Parties shall
agree. The Additional Closing with respect to any Additional Project shall be
scheduled within 60 days following DEVCO's election pursuant to Section 4
hereof to accept such Additional Project. The DEVCO Entity shall be responsible
for all closing costs. The purchase consideration for each Additional Project
payable to the applicable Project Transferor, which purchase consideration
shall be such Project Cost incurred by the Project Transferor through the date
of the transfer, shall be paid in the form of a promissory note of such Project
Entity, on such terms (including interest rate) as shall be agreed to by the
parties, together with all accrued interest thereof) upon the first to occur of
(i) the 6 month anniversary of such promissory note or (ii) the date upon which
such Project Entity receives the proceeds from any construction or permanent
financing of the applicable Project, whether in the form of a construction or
permanent loan or in the form of a sale/leaseback transaction such note, if
requested by the Project Transferor, to be secured by a mortgage or deed of
trust on the real property comprising such Project.


                                   ARTICLE 5
                            DEVELOPMENT OF PROJECTS

         5.1      Project Development. At the applicable Initial Closing with
respect to any Initial Projects and at the applicable Additional Closing with
respect to any Additional Projects, the applicable Acquiring Entity will enter
into a Development Agreement with the applicable Contributing Party for the
Project acquired by such Acquiring Party from such Contributing Party in
accordance with Articles 3 or 4 hereof. Notwithstanding the foregoing, the
Parties intend for each of the HCR Affiliates and the ALS Affiliates,
respectively, to have a substantially equal opportunity to serve as the
Developing Party with respect to the development of Projects hereunder (on a
development fee opportunity basis). Accordingly, if during any calendar year
the aggregate development fees paid to one Party and its Affiliates
(collectively, the "Advantaged Party") exceeds the aggregate development fees
paid to the other Party and its Affiliates (collectively, the "Disadvantaged
Party") by an amount in excess of One Million Dollars ($1,000,000) (the amount
of such shortfall, the "Development Shortfall"), then in the following calendar
year the opportunity pursuant to this Section 5.1 to serve as Developer shall
first be allocated to the Disadvantaged Party, and shall not be allocated on
the basis of the Contributing Party, until such time as such Development
Shortfall is substantially eliminated, on a pro forma basis.

         5.2      Project Financing. The Developing Party shall arrange the
placement of debt financing for the Acquiring Entity with respect to each
Project to be developed by such Developing Party. Upon the funding of such
financing, the Acquiring Entity shall pay to such Developing Party a placement
fee equal to one percent (1%) of the total amount of the debt placed by such
Developing Party and the Developing Party will be solely responsible for the
fees of any outside brokers up to such one percent (1%) amount. If a guaranty
shall be required, ALS and HCR will jointly and severally guarantee all such
debt, and if either or both of the Parties are called on as guarantors to pay
such obligations pursuant to their



                                      13
<PAGE>   17



guaranties, then (subject to Section 8.2(d) hereof) the Parties shall make
payments on such obligations in proportion to their Percentage Interests, so
that at all times neither Party has paid more than its proportionate share of
such obligations based on its Percentage Interest. Any failure by a Party to
pay its proportionate share of such obligations shall entitle the other Party
to indemnification pursuant to Article 11 hereof. All debt and equity financing
for each Project shall be subject to approval by DEVCO.


                                   ARTICLE 6
                  MANAGEMENT OF FACILITIES; FACILITY BRANDING

         6.1      Management. At the Initial Closing with respect to all 
Initial Projects and at the applicable Additional Closing with respect to all
Additional Projects, the applicable Acquiring Entity shall enter into a
Management Agreement with ALS, in the form attached hereto as Exhibit B,
pursuant to which ALS shall provide management services with respect to such
Project (and the resulting Facility). During the term of any Management
Agreement, the applicable Facility shall operate under the trade names and
service marks of ALS, based upon the applicable building and service type, in
the manner contemplated by such Management Agreement.


                                   ARTICLE 7
                 ALTERNATIVE OWNERSHIP AND OPERATING STRUCTURES

         7.1      Determination of Ownership and Operating Structures. Prior to
the acquisition of any Project by any Acquiring Entity in accordance herewith,
the Board of Managers, shall determine the optimal ownership and operating
structure with respect to the development, construction, ownership and
operation of such Project (and the resulting Facility).

         7.2      Structural Guidelines. Subject to further discussion and 
agreement by and among the Parties and subject in each case to DEVCO approval,
it is currently anticipated that in the design of ownership and/or operating
structures for Projects, the following features will be implemented:

                  (i)      Project Entities will generally be conduit entities
         managed or controlled by DEVCO;

                  (ii)     DEVCO will generally have an equity ownership 
         interest in each Project Entity and other investors ("Project
         Investors") will acquire the remaining equity ownership interest in
         each Project Entity in consideration of an equity contribution payable
         in cash to the Project Entity;

                  (iii)    Project Entity will either own a fee interest in a
         Project (and the resulting Facility) or will lease a Project (and the
         resulting Facility) from DEVCO;



                                      14
<PAGE>   18



                  (iv)     Pursuant to the governing documents of each Project
         Entity, (a) losses will generally be allocated disproportionately to
         Project Investors and (b) DEVCO will generally have a call option
         pursuant to which DEVCO may acquire, under certain terms and
         conditions, the equity interest held by the Project Investors in such
         Project Entity.


                                   ARTICLE 8
                   TRANSFER RESTRICTIONS AND PURCHASE OPTIONS

         8.1      Restrictions on Transferability of Interests. Neither ALS nor
HCR shall transfer its ownership interest in DEVCO except to the other Party or
to one of the transferring party's wholly-owned Affiliates. For purposes of
this Section 8.1, a "transfer" means any disposition of an interest or any
interest therein, including, without limitation, any sale, gift, assignment,
pledge or encumbrance, whether such disposition occurs voluntarily, by
operation of law or otherwise; provided, however, that transfer shall not
include a merger, consolidation or other business combination of a Party with
or into another Person or the sale or disposition of all or substantially all
of the assets of a Party (in one or a series of transactions).

         8.2      Facility Call Options.

                  (a)      As to each Facility, DEVCO hereby grants to the
         Contributing Party thereof the right to purchase all of DEVCO's
         ownership interest in such Facility at the fair market value
         (determined as set forth below) pursuant to the terms and conditions
         set forth herein (the "Facility Call Option"). The Facility Call
         Option shall be first exercisable with respect to a Facility upon the
         last to occur of (i) the date upon which such Facility achieves
         Facility Stabilization and (ii) the date upon which DEVCO acquires,
         directly or indirectly, ownership of 100% of the equity interests in
         the Project Entity owning such Facility, and shall be exercisable at
         any time during the six (6) months thereafter (the "Facility Option
         Period"). As to each Facility, DEVCO shall provide the applicable
         Contributing Party notice of the commencement of the applicable
         Facility Option Period. The Facility Call Option shall be exercised by
         written notice from such Contributing Party to DEVCO during the
         Facility Option Period. If a Contributing Party (i) does not exercise
         its Facility Call Option with respect to a Facility within the
         Facility Option Period relating thereto or (ii) irrevocably notifies
         DEVCO and the Parties in writing that it elects not to exercise such
         Facility Call Option with respect to such Facility, then the Party
         that is not an Affiliate of such Contributing Party (the
         "Non-Contributing Party") shall thereafter have the right to exercise
         such Facility Call Option with respect to such Facility as if it were
         the Contributing Party, provided that such option shall expire on the
         date (the "Option Expiration Date") which is the last to occur of (i)
         ninety (90) days after the Non-Contributing Party first has the right
         to exercise such option or (ii) the end of the Facility Option Period.



                                      15
<PAGE>   19



                  (b)      The purchase price to be paid by the Party 
         exercising the Facility Call Option shall be the fair market value of
         DEVCO's ownership interest in each Facility which shall be based upon
         the fair market value of such Facility (including all of its assets
         and assumed liabilities), determined as of the end of the calendar
         month preceding the date on which a Facility Call Option is exercised.
         For the purpose of determining fair market value, whether by agreement
         of the parties or by appraisal as hereafter provided, (i) the terms of
         any debt to be assumed by the Exercising Party shall be taken into
         account, (ii) if ALS is the Exercising Party, fair market value shall
         be determined as if the management fees to be paid to ALS pursuant to
         the applicable Management Agreement were five percent (5%) and (iii)
         if HCR is the Exercising Party, the fair market value shall take into
         account the management fees to be paid to ALS pursuant to the
         applicable Management Agreement. The fair market value of a Facility
         shall be as agreed upon by the Parties and, if the Parties are unable
         to promptly agree upon such value, such value shall be the fair market
         value of such Facility as established by an appraiser designated by
         the Parties. If the Parties are unable to agree upon an appraiser,
         then each Party will designate an appraiser and the two appraisers
         will each determine a fair market value. If the fair market value
         amounts determined by the two appraisers are equal to or within 5% of
         their average, then the fair market value shall be equal to such
         average. Otherwise, the two appraisers will mutually select and
         appoint a third appraiser to determine the fair market value of the
         Facility; provided, however, that if three appraisals are obtained,
         then the fair market value of the Facility shall not be greater than
         the higher of the fair market values determined by the first two
         appraisals or be less than the lesser of the fair market values
         determined by the first two appraisals. Each party will bear equally
         the fees and expenses of the appraiser jointly agreed upon or
         selected, but each party will be solely responsible for the fees and
         expenses of any appraiser selected solely by such Party. Each
         appraiser selected hereunder shall be a reputable appraisal firm which
         has substantial experience in appraising commercial real estate and
         long term care and/or assisted living facilities and each appraisal
         shall be in MAI form. All appraisers shall have complete access to the
         relevant books and records of the Facility they are appraising during
         the conduct of their appraisals.

                  (c)      If a Contributing Party exercises its Facility Call
         Option, then it shall pay the purchase price for DEVCO's ownership
         interest in the Facility in respect of which such option is exercised
         in cash.

                  (d)      At the closing of any Facility Call Option, which 
         shall occur not later than the date which is 30 days after the
         exercise of the Facility Call Option,

                   (i)     DEVCO shall deliver to the party exercising the
                           Facility Call Option (the "Exercising Party"), at
                           the Exercising Party's election, either an
                           instrument evidencing the transfer of (x) the
                           Facility being purchased



                                      16
<PAGE>   20



                           and sold or (y) DEVCO's interest in the entity which
                           owns the Facility, in each case free and clear of
                           all security interests, liens and restrictions
                           (other than restrictions imposed by this Agreement
                           and the Ancillary Agreements and debt to be
                           expressly assumed by the Exercising Party), together
                           with such other documents as such Exercising Party
                           may reasonably request in connection therewith; and

                  (ii)     The Exercising Party shall deliver to DEVCO cash
                           constituting the purchase price for the Facility,
                           together with such other documents as DEVCO may
                           reasonably request.

         At the time of the exercise of a Facility Call Option, if either Party
         has guaranteed any financing of the Facility subject to such option,
         then the Party whose Affiliate is exercising such option shall obtain
         a release of the other Party's guaranty as a condition precedent to
         its right to close on the Facility which is the subject of the
         Facility Call Option.

                  (e)      Notwithstanding any provision contained in this 
         Section 8.2 to the contrary:

                    (i)    if a Facility Call Option is exercised pursuant to
                           this Section, then such purchase may be made by an
                           Affiliate of the Exercising Party, but no such
                           assignment to such Affiliate shall relieve such
                           Exercising Party from any obligations hereunder; and

                   (ii)    all closing costs, including any real estate
                           transfer fee which arises in connection with any
                           purchase and sale hereunder shall be borne by the
                           Exercising Party.

                  (f)      If a Facility Call Option with respect to a Facility
         is not exercised by the Option Expiration Date, then DEVCO shall
         promptly offer (in such commercially reasonable manner as it shall
         determine) to sell its interest in such Facility on commercially
         reasonable terms and otherwise in compliance with the Operating
         Agreement (DEVCO). The proceeds of such sale (after payment of all
         costs, debts or other liabilities relating to such Facility or the
         sale thereof) shall be distributed by DEVCO to the Parties; provided,
         however, that if the purchaser of the Facility takes subject to the
         Management Agreement, HCR's share of the sale proceeds, or its
         obligation to contribute to any shortfall arising out of the repayment
         of indebtedness, shall be increased or reduced, respectively, by an
         amount equal to HCR's Percentage Interest (as a fraction of one) times
         the product obtained by multiplying two (2%) percent of the previous
         years' revenues generated by such Facility by the number of years
         remaining in the term of the Management Agreement which product shall
         be discounted to present value at seven percent (7%).

         demand, action or proceeding for which indemnification will be sought

         claim, demand, action or proceeding is a third party claim, demand,
         action or proceeding, the indemnifying party will have the right, at

         acceptable to the indemnified party. The indemnified party shall have
         the right to participate, at its own expense, with respect to any such
         third party claim, demand, action or proceeding. In connection with
         any such third party claim, demand, action or proceeding, the parties

         written consent of the indemnified party, such consent not to be
         unreasonably withheld or delayed.

                                 MISCELLANEOUS

         12.1     Entire Agreement; Amendment. This Agreement and the other
agreements and documents executed in connection herewith, constitute the entire
agreement between the parties pertaining to the subject matter of this
Agreement, and supersede all prior agreements, promises, covenants,
arrangements, communications, representations or warranties, whether oral or
written, by any officer, employee or representative of any party hereto. No
amendment, supplement, modification or waiver of this Agreement shall be
binding unless executed in writing by the party to be bound thereby. No waiver
of any of the provisions of this Agreement shall be deemed or shall constitute
a waiver of any other provision of this Agreement, whether or not similar, nor
shall such waiver constitute a continuing waiver unless otherwise expressly
provided.

         12.2     Fees and Expense. Whether or not the transactions 
contemplated by this Agreement are consummated, and except as expressly
provided herein or in any Ancillary Agreement, each of the parties hereto shall
pay the fees and expenses of such party's counsel, accountants, brokers,
consultants, investment bankers and other experts incident to the negotiation
and preparation of this Agreement and the consummation of the transactions
contemplated by this Agreement.

         12.3     Confidentiality. Except to the extent permitted by this
Section 12.3 hereof, the parties hereto will at all times hold and cause their
consultants and advisors to hold in confidence the information contained in
this Agreement. In addition, each party (the "Receiving Party") who receives
any Confidential Information concerning the other party (the "Disclosing
Party") will at all times hold and cause its advisors and representatives to
hold in strict confidence such Confidential Information which shall have been
or will be furnished by the Disclosing Party to the Receiving Party or its
employees, advisors and representatives in connection with the transactions
contemplated by this Agreement and/or



                                      22
<PAGE>   26



any Ancillary Agreements. All such Confidential Information shall be disclosed
by a Receiving Party only to its employees, advisors, agents, officers,
directors and representatives engaged in the evaluation of such information. If
the transactions contemplated by this Agreement are not consummated, regardless
of the reason therefor, then such confidence will be maintained by the
Receiving Party. The provisions of this Section 12.3 shall not apply to the
extent that such Confidential Information (a) was previously known to the
Receiving Party prior to disclosure by the Disclosing Party, (b) is in the
public domain through no fault of the Receiving Party, (c) is lawfully acquired
by the Receiving Party from a third party under no obligation of confidence to
the Disclosing Party, or (d) is required by any law or by any governmental or
judicial body to be disclosed; provided that upon receiving notice of a
required disclosure under this clause (d), the Receiving Party will promptly so
notify the Disclosing Party in writing. Such Confidential Information may be
used in connection with the business of DEVCO or any DEVCO Entity, but shall
otherwise not be used to the detriment of the Disclosing Party in any manner
and all Confidential Information provided by the Disclosing Party to the
Receiving Party, including all copies and extracts thereof, will be returned to
the Disclosing Party immediately upon such party's written request.

         In addition to the above, for purposes of this Section 12.3 the term
"Confidential Information" shall mean any data or information that is
designated as "confidential" by the Disclosing Party, is of value to the
Disclosing Party and is not generally known to competitors of the Disclosing
Party or to the public, and whose confidentiality is maintained. Confidential
Information shall include, but not be limited to, written lists of the
Disclosing Party's current or potential residents or other customers, the
identity of various suppliers, non-public information concerning the Disclosing
Party's executives and employees and its financial affairs, business plans,
services, research, development, purchasing, accounting, engineering and
marketing.

         12.4     Further Assurances. Following the Closing, each party will
execute such further documents and perform such further acts as may be
reasonably necessary to consummate the transactions contemplated by this
Agreement and the Ancillary Agreements and in accordance with the terms of this
Agreement and the Ancillary Agreements, to aid the more efficient execution of
the transactions contemplated hereby and thereby.

         12.5     No Liens. ALS and HCR, and each one individually, hereby
agrees to keep its ownership interest in DEVCO and any DEVCO Entity free and
clear from any and all security interests, liens, restrictive covenants or
other encumbrances in favor of any and all third parties.

         12.6     Public Statement. Each party to this Agreement will consult
with the other party prior to issuing any press release or making any other
public statement with respect to the transactions contemplated in this
Agreement, and will not issue any such release or make any such statement
without the approval of the other party (in its sole discretion), except such



                                      23

disclosure as is required or otherwise reasonably appropriate pursuant to any
state or federal securities law or the rules and regulations of any relevant
securities exchange or quotation system upon which ALS's or HCR's securities
are then listed or traded.

         12.7     Applicable Law. All questions concerning the construction,
validity and interpretation of this Agreement, and the performance of the
obligations imposed by this Agreement, shall be governed by the law of the
State of Delaware, without giving effect to principles of conflicts of laws.

         12.8     Binding Effect; Assignment. This Agreement and all of the
provisions hereof shall be binding upon and inure to the benefit of the Parties
and their respective successors and assigns, but neither this Agreement nor any
of the rights, interests or obligations hereunder shall be assigned or
delegated by any of the Parties without the prior written consent of the other
Party, whether by operation of law or otherwise.

party. The arbitration shall be conducted before a panel of three (3)
arbitrators, one selected by HCR, one selected by ALS, and one selected by

void or unenforceable, the remainder of the provisions of this Section 12.16
shall remain in full force and effect. All notices in connection with the
