            A. Landlord and Tenant have entered into that certain Master Lease
dated as of April 9, 2002 (as amended, modified or revised prior to the date

Master Lease.

            B. Landlord and Tenant now desire to amend the Master Lease as more
particularly set forth in this Second Amendment.

                               A G R E E M E N T

            NOW, THEREFORE, taking into account the foregoing Recitals, and in
consideration of the mutual covenants and agreements contained herein, and for
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties hereto agree as follows:

            1. AMENDMENTS TO MASTER LEASE.

                  (a) INITIAL CAPEX FUNDING. Notwithstanding anything to the
      contrary set forth in the Master Lease, the Initial CapEx Funding shall be
      available for disbursement to Tenant, on the terms and conditions set
      forth in the Master Lease as modified by this Second Amendment, until
      December 31, 2004. Any portion of the Initial CapEx Funding remaining
      unused at December 31, 2004 shall become unavailable to Tenant, and
      Landlord's Investment and Minimum Rent shall then be adjusted in the
      manner described in Section 8.3(b) of the Master Lease.

                  (b) CAPEX BUDGET. Funds from the Initial CapEx Funding shall
      be available for disbursement to Tenant for payment or reimbursement of
      capital expenditures on those CapEx Items shown on the revised budget for
      CapEx Items attached hereto as Exhibit A, which Landlord has approved.
      Landlord may, in its reasonable discretion, request that Tenant from time
      to time update the operative budget for CapEx Items.

                  (c) EXCLUDED FACILITIES. Except for funds described in
      Tenant's draw request pending as of the date of this Second Amendment,
      which may be made available to Tenant in accordance with the provisions of
      the Master Lease, no further funds from the Initial CapEx Funding (or
      otherwise) shall be available to Tenant to fund CapEx Items at the
      Facilities located in Tampa, Florida, Ocala, Florida and Lancaster, Texas.
      No future budget describing CapEx Items shall include any further requests
      for CapEx Items at such Facilities.

      pursuant to the terms of this Second Amendment, the terms and conditions
      of the Master Lease shall remain unmodified and in full force and effect.
      In the event of any inconsistencies between the terms of this Second
      Amendment and any terms of the Master Lease, the terms of this Second
      Amendment shall govern and prevail.

            2. DISPOSITION FACILITIES. Tenant acknowledges that, pursuant to

      further represents and warrants that the Master Lease is the valid and
      binding obligations of Tenant and is in full force and effect and is fully
      enforceable by Landlord against Tenant in accordance with its terms. Each
      entity comprising Tenant specifically acknowledges and affirms that,
      except as expressly modified by this Second Amendment, its obligations
      under the Master Lease shall not be diminished or otherwise affected by
      this Second Amendment.

                  (b) Guarantor hereby acknowledges and affirms its obligations
      under the Guaranty, and further represents and warrants that the Guaranty
      is the valid and binding obligation of Guarantor and is in full force and
      effect and is fully enforceable by Landlord against Guarantor in
      accordance with its terms. Guarantor specifically acknowledges and affirms
      that, except as expressly modified by this Second Amendment, its
      obligations under the Guaranty shall not be diminished or otherwise
      affected by this Second Amendment.

            4. FURTHER INSTRUMENTS. Each of the undersigned will, whenever and
as often as it shall be reasonably requested so to do by another party, take all
actions reasonably required and shall cause to be executed, acknowledged or
delivered, any and all such further instruments and documents as may be

                                GUARANTY OF LEASE
                         AND LETTER OF CREDIT AGREEMENT

            THIS GUARANTY OF LEASE AND LETTER OF CREDIT AGREEMENT (this
"GUARANTY") is executed as of April 9, 2002 by ALTERRA HEALTHCARE CORPORATION, a
Delaware corporation ("GUARANTOR"), in favor of the ENTITIES LISTED ON SCHEDULE
1 (collectively, "LANDLORD").

                                R E C I T A L S

            A. Landlord and ALS LEASING, INC., a Delaware corporation ("ALS
LEASING"), and ASSISTED LIVING PROPERTIES, INC., a Kansas corporation ("ALP"
and, collectively with ALS Leasing, "TENANT"), have entered into that certain
Master Lease of even date herewith (the "LEASE") whereby Landlord has agreed to
lease to Tenant the Premises, as more specifically set forth in the Lease. All
initially capitalized terms used herein and not otherwise defined herein shall
have the meaning ascribed to such terms in the Lease.

            B. Landlord and Tenant have entered into that certain Letter of
Credit Agreement (the "LETTER OF CREDIT AGREEMENT") of even date herewith,
whereby Tenant has agreed to post and maintain a letter of credit as partial
collateral for Tenant's obligations under the Lease, as more particularly set
forth therein.

            C. It is a condition to Landlord's obligations under the Lease that
the Guarantor execute and deliver this Guaranty.

                              A G R E E M E N T S

            NOW, THEREFORE, in consideration of Landlord entering into the Lease
with Tenant, and other good and valuable consideration the receipt and
sufficiency of which are hereby acknowledged, Guarantor agrees as follows:

            1. GUARANTY.

            Guarantor hereby absolutely and unconditionally guarantees to
Landlord the following (collectively, the "GUARANTEED OBLIGATIONS"):

                  (a) payment in full by Tenant of all Rent (including, without
      limitation, Minimum Rent and Manlius Debt Service) and other charges,
      reserves and other amounts due under the Lease in the manner and at the
      time prescribed in the Lease;

                  (b) the full, complete and timely performance by Tenant of all
      covenants, indemnities and other obligations under the Lease including,
      without limitation, any indemnity or other obligation of Tenant which
      survives the expiration or earlier termination of the Lease;

                  (c) the full, complete and timely performance by Tenant of all
      covenants, agreements and other obligations under the Letter of Credit
      Agreement;

<PAGE>

                  (d) the accuracy and truthfulness in all material respects of
      all of the representations and warranties made by Tenant under the Lease;
      and

                  (e) all costs of collection or enforcement incurred by
      Landlord in exercising any remedies provided for in the Lease or the
      Letter of Credit Agreement at law or in equity with respect to the matters
      set forth in clauses (a) through (d) inclusive, above.

            2. PERFORMANCE BY GUARANTOR.

            If any Minimum Rent, other Rent or other charge, reserve or other
amount due under the Lease shall not be paid, or any obligation not performed as
required by the Lease or the Letter of Credit Agreement, then upon demand by
Landlord, Guarantor shall pay within ten (10) days of demand by Landlord such
sums and perform such obligations as required by the Lease or the Letter of
Credit Agreement, as applicable, without regard to:

                  (a) any defense, set-off, or counterclaim which Guarantor or
      Tenant may have or assert;

                  (b) whether or not Landlord shall have instituted any suit,
      action or proceeding or exhausted its remedies or taken any steps to
      enforce any rights against Tenant or any other person to collect all or
      any part of such sums, either pursuant to the provisions of the Lease, the
      Letter of Credit Agreement or at law or in equity (it being understood
      that this is a guaranty of payment and not collection, and Guarantor's
      liability for such payment shall be primary); or

                  (c) any other condition or contingency.

            Guarantor waives any right of exoneration and any right to require
Landlord to make an election of remedies. Guarantor covenants and agrees that it
shall not cause any default under the Lease or the Letter of Credit Agreement.

            3. GUARANTOR'S REPRESENTATIONS AND WARRANTIES.

            Guarantor hereby represents and warrants unto Landlord that:

                  (a) this Guaranty constitutes a legal, valid, and binding
      obligation of Guarantor and is fully enforceable against Guarantor in
      accordance with its terms;

                  (b) all the issued and outstanding capital stock of each
      entity comprising Tenant is owned beneficially and of record by Guarantor;

                  (c) Guarantor is a corporation duly organized, validly
      existing and in good standing under the laws of the State of Delaware and
      is duly authorized and qualified to do all things required of it under
      this Guaranty; and

                  (d) this Guaranty is duly authorized, executed and delivered
      by and binding upon Guarantor.

                                        2
<PAGE>

            Any material breach by Guarantor of the representations and
warranties set forth herein shall be a default under this Guaranty.

            4. WAIVER.

            Guarantor hereby knowingly, voluntarily and unequivocally waives:

                  (a) all notice of acceptance hereof, protest, demand and
      dishonor, presentment and demands of any kind now or hereafter provided
      for by any statute or rule of law;

                  (b) any and all requirements that Landlord institute any
      action or proceeding, or exhaust any or all of Landlord's rights, remedies
      or recourses, against Tenant or anyone else as a condition precedent to
      bringing an action against Guarantor under this Guaranty, it being
      expressly agreed that the liability of Guarantor hereunder shall be
      primary and not secondary;

                  (c) any defense arising by reason of any disability,
      insolvency, bankruptcy, lack of authority or power, death, insanity,
      minority, dissolution or any other defense of Tenant, its successors and
      assigns, Guarantor or, if applicable, any other guarantor of the
      Guaranteed Obligations (even though rendering same void, unenforceable or
      otherwise uncollectible), it being agreed that Guarantor shall remain
      liable hereon regardless of whether Tenant or any other such person be
      found not liable thereon for any reason;

                  (d) the benefits of any rights and defenses that are or may
      become available to Guarantor by reason of Sections 2787 to 2855,
      inclusive, 2899 and 3433 of the California Civil Code;

                  (e) any claim Guarantor might otherwise have against Landlord
      by virtue of Landlord's invocation of any right, remedy or recourse
      permitted it hereunder, under the Letter of Credit Agreement or under the
      Lease or otherwise available at law or equity;

                  (f) any failure, omission, delay or lack on the part of
      Landlord or Tenant to enforce, assert or exercise any right, power or
      remedy conferred on Landlord or Tenant in the Lease or this Guaranty or
      any action on the part of Landlord granting a waiver, indulgence or
      extension to Tenant, Guarantor or any other guarantor;

                  (g) the voluntary or involuntary liquidation, dissolution,
      sale or other disposition of all or substantially all the assets of
      Tenant, marshalling of assets or liabilities, receiverships, insolvency,

      or the Letter of Credit Agreement in any such proceeding;

      replacement (whether or not in accordance with terms of the Lease) of the
      Premises or any portion thereof;

                  (i) any release or other reduction of the Guaranteed

      Credit Agreement) of any letter of credit issued and outstanding pursuant
      to the Letter of Credit Agreement; and

                  (k) any defense or claim available to Guarantor as a result of
      Tenant's exercise of its right, or compliance with its obligation, to
      purchase the Premises (or any portion thereof) pursuant to the Lease.

            This Guaranty shall apply notwithstanding any extension or renewal
of the Lease, or any holdover following the expiration or termination of the
Term or any renewal or extension of the Term.

            5. FINANCIAL STATEMENTS AND LEGAL PROCEEDINGS.

            The financial statements heretofore given to Landlord by or on
behalf of Guarantor:

                  (a) have been prepared in accordance with generally accepted
      accounting principles consistently applied throughout the periods covered
      thereby;

                  (b) are true and correct in all material respects;

                  (c) present fairly the results of operations of the parties
      described therein for the respective periods covered thereby; and

                  (d) reflect accurately, in all material respects, the books
      and records of account of the parties described therein as of such dates
      and for such periods.

            Subject to the foregoing, Guarantor hereby warrants and represents
unto Landlord that any and all balance sheets and other financial statements and
data which have heretofore been given to Landlord with respect to Guarantor
fairly and accurately present the financial condition of Guarantor.

            6. SUBSEQUENT ACTS.

            Without notice to, consideration to, or the consent of, Guarantor:

                  (a) the Lease, and Tenant's rights thereunder, may be
      modified, amended, renewed, assigned or sublet;

                                        4
<PAGE>

                  (b) the Letter of Credit Agreement, and Tenant's rights and
      obligations thereunder, may be modified, amended, renewed or assigned;

                  (c) any additional parties who are or may become liable for
      the Guaranteed Obligations may hereafter be released from their liability
      hereunder and thereon; and/or

                  (d) Landlord may take, or delay in taking or refuse to take,
      any and all action with reference to the Lease or the Letter of Credit
      Agreement (regardless of whether same might vary the risk or alter the
      rights, remedies or recourses of any Guarantor), including specifically
      the settlement or compromise of any amount allegedly due thereunder.

            No such acts shall in any way release, diminish, or affect the
absolute nature of Guarantor's obligations and liabilities hereunder.
Guarantor's obligations and liabilities under this Guaranty are primary,
absolute and unconditional under any and all circumstances and until the
Guaranteed Obligations and any other obligations of Guarantor under this
Guaranty are fully and finally satisfied (including any such Guaranteed
Obligation that survives the termination of the Lease), such obligations and
liabilities shall not be discharged or released, in whole or in part, by any act
or occurrence which might, but for this Section 6, be deemed a legal or
equitable discharge or release of a Guarantor.

            7. SUCCESSORS AND ASSIGNS.

            This Guaranty may be enforced as to any one or more breaches either
separately or cumulatively, shall inure to the benefit of Landlord (and its
successors and assigns) and shall be binding upon Guarantor (and its successors
and assigns). All references herein to "LANDLORD" shall mean the entities
comprising the above-named Landlord and any subsequent owner of any portion of
Landlord's interest in the Lease or assignee of any portion of Landlord's rights
under the Letter of Credit Agreement. No transfer by Guarantor of its
obligations hereunder shall operate to release Guarantor from such obligations.

            8. REMEDIES CUMULATIVE.

            All rights, remedies and recourses afforded to Landlord by reason of
this Guaranty, or otherwise, are separate and cumulative and may be pursued
separately, successively or concurrently, as occasion therefor shall arise and
are non-exclusive and shall in no way limit or prejudice any other legal or
equitable right, remedy or recourse which Landlord may have.

            9. SUBORDINATION; NO SUBROGATION.

            If for any reason whatsoever any entity comprising Tenant now or
hereafter becomes indebted to Guarantor or any Affiliate of Guarantor, such
indebtedness and all interest thereon shall at all times be subordinate in all
respects to the Guaranteed Obligations. Notwithstanding anything to the contrary
contained in this Guaranty or any payments made by Guarantor, Guarantor shall
not have any right of subrogation in or under the Lease or the Letter of Credit
Agreement or to participate in the rights and benefits accruing to Landlord

            11. SEVERABILITY.

            If any provision of this Guaranty or the application thereof to any
person or circumstance shall, for any reason and to any extent, be invalid or
unenforceable, neither the remainder of this Guaranty nor the application of
such provision to any other persons or circumstances shall be affected thereby,
but rather the same shall be enforced to the greatest extent permitted by law.

            12. ATTORNEYS' FEES.

            If Landlord or Guarantor brings any action to interpret or enforce
this Guaranty, or for damages for any alleged breach thereof, the prevailing

costs.

A party may designate a different address by notice as provided above. Any
notice, demand or request so delivered (whether accepted or refused) shall be
deemed to have been given and received on the date of delivery established by
the U.S. Post Office return receipt or the carrier's proof of delivery or, if
not so given, upon on the day received (provided that such notice or instrument
shall be deemed received on the next succeeding business day if received after
5:00 p.m. (local time)). Delivery to any officer, general partner of principal
of a party shall be deemed delivery to such party. If Landlord notifies Tenant
of the name and address of any lender, Tenant shall deliver a copy of all its
notices concurrently to such lender.

            17. INCORPORATION OF RECITALS.

            The Recitals set forth above are hereby incorporated by this
reference and made a part of this Guaranty. Guarantor hereby represents and
warrants that the Recitals are true and correct.

            18. PRESERVATION OF GROSS REVENUES.

            Guarantor acknowledges that a fair return to Landlord on and
protection of its investment in the Premises is dependent, in part, on Tenant's
dedication to the Business and the concentration on each Facility of similar
businesses of Tenant and its Affiliates (including Guarantor) in the
geographical area of such Facility. Guarantor further acknowledges that the
diversion of residents or patient care activities from any Facility to other
facilities owned or operated by Tenant or its Affiliates (including Guarantor)
at any time during the Term will have a material adverse affect on the value and
utility of such Facility. Therefore, Guarantor agrees that during the Term and
for a period of one (1) year thereafter, neither Guarantor nor any of its
Affiliates shall, without the prior written consent of Landlord: (a) operate,
own, participate in or otherwise receive revenues from any other business
providing services similar to those of the Business of any Facility within an
eight (8) mile radius of such Facility, provided, however, that Tenant and its
Affiliates may continue to operate, own, manage, participate in or otherwise
receive revenues from any Exempt Facility so long as, after the date hereof, no
aspects of the operations or management of any Exempt Facility are changed in
any manner that results in such Exempt Facility becoming more competitive with
any Facility, provided, however, that routine maintenance and capital
expenditures in the ordinary course of business and minor variations in the
number of beds or living units, as applicable, in such other facilities shall
not be deemed to violate the foregoing, (b) except as is necessary to provide
residents or patients with an alternative level of care not provided or
available within any other reasonably proximate Facility, recommend or solicit
the removal or transfer of any resident or patient from any Facility to any
other nursing, health care, senior housing or retirement housing facility or
divert actual or potential residents, patients or care activities of the
Business conducted at any Facility to any other facilities owned or operated by
Tenant or its Affiliates or from which they receive any type of referral fees or
other compensation for transfers, or (c) employ for other businesses any
management or supervisory personnel working on or in connection with any portion
of the Business or any Facility. The terms of this Section 18 shall survive the
termination or expiration of the Lease.
