       (iii)  Deliver to Purchaser a certificate dated as of the Closing

     Closing Date which relate to periods prior to the Closing Date; and

(ii) Take such actions and property execute and deliver such 
     further instruments as Seller may reasonably request to assure, complete 
     and evidence the transaction provided for in this Agreement.

12.   MUTUAL

     Following the execution of this Agreement, Purchaser and Seller agree:

     a. If any event should occur, either within or without the knowledge or 
control of Purchaser or Seller, which would prevent fulfillment of the 
conditions to the obligations of any party hereto to consummate the 
transaction contemplated by this Agreement, to use its or their reasonable 
efforts to cure the same as expeditiously as possible; and

     b. To cooperate fully with each other in preparing, filing, prosecuting, 
and taking any other actions which are or may be reasonable and necessary to 
obtain the consent of any governmental instrumentality or any third party or

13.   PURCHASER'S CONDITIONS

     All obligations of Purchaser under this Agreement are subject to 
fulfillment of each of the following conditions, any one or all or which may 
be waived in writing by Purchaser:

     a. SELLER'S REPRESENTATIONS AND WARRANTIES TRUE AT CLOSING.  Seller's 
representations and warranties contained in this Agreement or in any 
certificate or document delivered in connection with this Agreement or the 

                                     14


transactions contemplated herein shall be true in all material respects at 
and as of the date of Closing as though such representations and warranties 
were then again made.

     b. SELLER'S PERFORMANCE.  Seller shall have performed all of its 
obligations under this Agreement that are to be performed prior to or at 
Closing to the extent the same have not been waived by Purchaser in 
accordance with the terms hereof.

     c. APPROVALS.  On or before the Closing Date, Purchaser shall have 
received all consents, approvals and licenses as may be necessary for it to 
own and to operate the Facility.

     d. NO DEFAULTS. Seller shall not be in default, where said default 
cannot be cured by Closing, under any mortgage, contract, lease or other 
agreement to which Seller is a party or by which Seller is bound and which 
affects or relates to the Real Property, the Personal Property or the 
Facility, including, but not limited to, the Facility Leases.

     e. DUE DILIGENCE REVIEW. Purchaser shall be satisfied with the results 
of its Feasibility Review, including but not limited to (i) Purchaser's 
approval of the physical condition of the Real Property and the structural 
condition of the Facility, including the results of the Environmental Report 
required hereunder to be delivered by Seller to Purchaser, (ii) Purchaser's 
review and
approval of all Property Documents and (iii) Purchaser's review of the zoning 
for the Real Property to confirm that the Real Property and the operation and 
development of the Facility is in compliance with all applicable zoning laws. 
In the event Purchaser has not advised Seller in writing on or before the 
date thirty (30) days following the mutual execution of this Agreement (the 
"Feasibility Period") of its objections to the results of its due diligence 
investigation and its election to terminate this Agreement, this condition 
shall be deemed not satisfied as of the date thereof.  Nothing herein shall 
be construed as amending or modifying in any manner the representations or 
warranties of Seller set forth in this Agreement, which representations and 
warranties shall be separate from and unaffected by Purchaser's Feasibility 
Review except as to any representations or warranties which, during the 
course of Purchaser's Feasibility Review, Purchaser obtains knowledge of 
falsity or inaccuracy and advises Seller in writing thereof.  In the event 
Purchaser elects to terminate this Agreement, the parties shall have no 
further rights or obligations hereunder, other than Purchaser's right to the 
return of its Earnest Money and Seller's obligation to pay any title 
cancellation and UCC search fees incurred as a result of such termination.

     f. TITLE REVIEW.  Within fifteen (15) days following receipt of the 
Title Report (together with legible copies of all of the recorded documents 
referenced therein as exceptions) and the Survey, Purchaser shall have 
reviewed and approved or disapproved those matters reflected on the Title 
Report and the Survey.  In the event Purchaser objects to any such matters, 
Purchaser shall advise Seller in writing of its objections within said 

                                     15


fifteen (15) day period; provided, however that such objections shall not 
include those items specifically excluded in Paragraph 4. Within ten (10) 
days of Seller's receipt of Purchaser's objections, Seller shall advise 
Purchaser in writing as to whether it intends to correct the defects to which 
Purchaser has objected.  If Seller fails to notify Purchaser within said ten 
(10) day period or timely notifies Purchaser of its refusal to correct some 
or all of such defects, Purchaser shall have ten (10) days following the 
earlier of (i) the expiration of said Seller's ten (10) day response period 
or (ii) the date Purchaser receives Seller's notice of refusal, to advise 
Seller of its decision to close, notwithstanding the defects, or to terminate 
this Agreement.  In the event of any such termination, neither party shall 
have any further rights or obligations hereunder, other than Seller's 
obligation to return or to direct the return of Purchaser's Earnest Money.  
Any matter reflected in the Title Report or the Survey not objected to in 
accordance with the terms hereof shall be deemed accepted by Purchaser;

     g. TITLE POLICY.  The Title Insurer shall issue to Purchaser as of the 
date of Closing, an ALTA Owner's extended coverage policy of title insurance 
for the Real Property and the Facility (the "Title Policy") with a value of 
not less than the amount of the Purchase Price insuring Purchaser's interest 
in the Real Property and the Facility, and subject to no exceptions other 
than those of the usual printed exceptions which are acceptable to Purchaser 
(the survey, parties in possession and mechanics lien exceptions being 
specifically unacceptable to Purchaser), the Existing Deed of Trust, and 
those exceptions to which Purchaser has not objected as provided for in 
Paragraph 13 f. above.

     h. UCC SEARCH.  On or before the Closing Date, Purchaser shall be 
satisfied with the results of the UCC search conducted by Seller pursuant to 
Paragraph 10.a.(xvi).

i. BOARD APPROVAL.  On or before the expiration of the Feasibility 
Period, Purchaser shall have obtained the approval of its Board of Directors 
to the acquisition of the Seller's Assets pursuant to the terms of this 
Agreement.

     j. ASSUMPTION OF EXISTING LOAN.  On or before the Closing Date, 
Purchaser shall have received the written consent of the Existing Lender to 
Purchaser's assumption of the Existing Loan, which consent shall not be 
subject to any terms or conditions which have not been approved by Purchaser.

     In the event any of the foregoing conditions are not satisfied or are 
not otherwise waived by Purchaser prior to the applicable period for 
satisfaction or waiver, Purchaser shall have the right to terminate this 
Agreement in accordance with the provisions of Paragraph 17 and in such event 
Purchaser shall receive a full refund of its Earnest Money together with 
all interest earned thereon.



                                     16

     All obligations of Seller under this Agreement are subject to the 
fulfillment, prior to or at Closing, of each of the following conditions, any 
one or all of which may be waived by Seller in writing:

     a. PURCHASER'S REPRESENTATIONS AND WARRANTIES TRUE AT CLOSING.  
Purchaser's representations and warranties contained in this Agreement or in

     Seller shall indemnify, defend and hold Purchaser harmless from and 
against:

judgments, reasonable costs, and other reasonable expenses, including, but 

                                     17


not limited to, reasonable attorney's fees, incident to any of the foregoing.

     For purposes of Paragraph 15.a., an obligation shall be deemed to 
"exist" as of the Closing Date if it relates to events which occurred prior 
to the Closing Date even if it is not asserted until after the Closing Date.

16.   PURCHASER'S INDEMNITY

     Purchaser shall indemnify, defend and hold Seller harmless from and 
against:

     a. Except as otherwise provided in this Agreement, any and all 
obligations relating to the ownership of the Seller's Assets and the operation

to, any obligations under any of the Facility Leases or Operating Contracts 
which Purchaser elects to assume at Closing and any obligations with respect 
to the Resident Deposits;

     b. Any and all damage, loss or liability resulting from any 
misrepresentation of a material fact, breach of warranty or nonfulfillment 
of any agreement on the part of Purchaser under this Agreement or from any

limited to, reasonable attorney's fees, incident to any of the foregoing.

17.   TERMINATION

     a. This Agreement may be terminated and the transaction contemplated 
herein abandoned at any time prior to Closing:

          (i) By mutual agreement of the parties;

          (ii) By Seller, if any of the conditions set forth in Paragraph 
     14 shall have become incapable of fulfillment prior to the Closing Date or
     such earlier date as may be specifically provided for the performance 
     thereof (as the same may be extended) through no fault of Seller and the
     same shall not have been waived by Seller;

          (iii) By Purchaser, if any of the conditions set forth in 
     Paragraph 13 shall have become incapable of fulfillment prior to the 
     Closing Date or such earlier date as may be specifically provided for the
     performance thereof (as the same may be extended) through no fault of 
     Purchaser and the same shall not have been waived by Purchaser;

                                     18


          (iv) By either Seller or Purchaser in the event of a material 
     breach by the other party of its obligations hereunder; or

          (v) If the Closing has not occurred by the Closing Date, unless 
     extended by mutual agreement of the parties.

     b. In the event that prior to the Closing Date, a material portion of 
the Real Property, the Facility or the Personal Property shall have been 
damaged or destroyed by fire or other casualty, or shall have been taken or 
condemned by any public or quasi-public authority under the power of eminent 
domain, Purchaser shall have the right to terminate this Agreement on 
written notice to Seller. In the event Purchaser elects not to terminate its 
rights hereunder, then Seller shall assign to Purchaser all of its rights to 
any insurance proceeds or condemnation award and all claims in the connection 
therewith.  In the event Purchaser exercises its termination rights 
hereunder, the parties shall have no further rights or obligations hereunder 
other than Purchaser's right to the return of its Earnest Money.

     c. Neither party to this Agreement may claim termination or pursue any 
other remedy referred to in Paragraph 17.a. on account of a breach of a 
condition, covenant or warranty by the other, without first giving such other 
party written notice of such breach and not less than ten (10) days within 
which to cure such breach.  The Closing Date shall be postponed, if 
necessary, to afford such opportunity to cure; provided, however, in no event 
shall the Closing Date be postponed beyond April 26, 1996.

     d. In the event of the termination of this Agreement by Seller under 
Paragraphs 17.a.(ii) or (iv) or under Paragraph 17(a)(v), and any such 
termination is due to the Closing having failed to occur as a result of a 
material breach by Purchaser of its obligations hereunder, Seller's sole 
remedy shall be to terminate this Agreement and to receive, as full and 
complete liquidated damages, the sum of (i) the Purchaser's Earnest Money and 
(ii) an amount equal to the actual total costs incurred by Seller in 
connection with the procurement of the Environmental Report, the preparation 
of the Survey, the cancellation of the escrow established with Escrow Agent 
hereunder, the cancellation of the title commitment and all reasonable fees 
charged to Seller by the Existing Lender in connection with procuring the 
consent of the Existing Lender to the assumption of the Existing Loan,
except that the total amount for all such costs under this item "(ii)" shall 
not exceed Ten Thousand Dollars ($10,000.00) (the "Additional Liquidated 
Damages"). The parties acknowledge and agree that the amount of damages which 
Seller may incur as a result of such termination may be difficult to 
ascertain and that the amount of the Earnest Money, together with the 
Additional Liquidated Damages, is a reasonable and fair estimate thereof, 
after which the parties shall have no further rights or obligations hereunder.

     e. In the event of the termination of this Agreement by Purchaser under 
Paragraphs 17.a.(iii), (iv) or (v) as a result of the Closing failing to 
occur due to a material breach by Seller of its obligations hereunder, 


                                     19


Purchaser shall have the right either to (i) terminate this Agreement and 
demand the return of its Earnest Money after which neither party shall have 
any further rights or obligations hereunder or (ii) seek specific performance 
of Seller's obligations hereunder or damages for Seller's breach of its 
obligations hereunder.

18.   EMPLOYEE BENEFITS

     On or before the Closing, Seller shall deliver to Purchaser a schedule 
(the "Benefits Schedule") setting forth all of the earned and accrued 
vacation, holiday and sick pay, and retirement and severance benefits and 
earned bonuses (the "Accrued Employee Benefits") which have accrued and are 
due to the employees of the Facility as of the Closing Date.  At Closing, 
Seller shall terminate all of the Facility employees effective as of the 
Closing Date and pay to all such employees the full amount of the Accrued 
Employee Benefits.  Upon the request of Purchaser, Seller agrees to provide 
to Purchaser written evidence that all such Accrued Employee Benefits have 
been fully paid to the employees of the Facility.

19.   RESIDENT SECURITY DEPOSITS

     At Closing, Seller shall provide Purchaser with an accounting of all 
resident security deposits being held by Seller as of the Closing Date (the 
"Resident Deposits"). Such accounting shall set forth the names of the 
residents or prospective residents for whom such funds are held, the amounts 
held on behalf of each resident or prospective resident and the Seller's 
warranty that the accounting is true, correct and complete.

20.   TRANSFER OF RESIDENT SECURITY DEPOSITS

     On the Closing Date, Seller shall do either of the following, the 
election of which shall be made by Purchaser: (i) transfer the Resident 
Deposits to the bank account designated by the Purchaser or (ii) grant to 
Purchaser a credit in the amount of said Resident Deposits against the 
payment of the remaining balance due on the Purchase Price.  In either event, 
Purchaser shall in writing acknowledge receipt of and expressly assume all 
Seller's financial and custodial obligations with respect thereto, it being 
the intent and purpose of this provision that, at Closing, Seller will be 
relieved of all fiduciary and custodial obligations with respect to said 
Resident Deposits, and that Purchaser will assume all such obligations and be 
directly accountable to the residents and prospective residents of the 
Facility, with respect thereto.  Following the Closing, Purchaser shall
be responsible for notifying each of the residents of the Facility of the 
Closing hereunder and the transfer of the Resident Deposits to Purchaser, 
which notice shall include the name, address and telephone number of 
Purchaser, all in accordance with applicable California law.




                                     20




21.   INDEMNITY FOR RESIDENT SECURITY DEPOSITS

     Notwithstanding the foregoing, Seller will indemnify and hold Purchaser 
harmless from all liabilities, claims and demands in the event the amount of 
the Resident Deposits transferred to the Purchaser's bank account or the 
credit for said Resident Deposits which has been applied against the Purchase 
Price, as provided in Paragraph 20, did not represent the full amount of 
such Resident Deposits then or thereafter shown to have been delivered to 
Seller by the current residents or prospective residents of the Facility.
