                                   ARTICLE VII
              SELLERS' AND ALTERRA'S REPRESENTATIONS AND WARRANTIES

         Sellers and Alterra, jointly and severally, represent and warrant to
Purchaser, as of the Closing Date, that:

         7.01. Status of Seller and Alterra. Sterling is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Kansas and is duly qualified to do business as a foreign corporation in each
state in which a Facility owned by it is located. ALS-Clare is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Delaware and is duly qualified to do business as a foreign corporation
in each state in which a Facility owned by it is located. Alterra is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware and is duly qualified to do business as a foreign
corporation in each state in which a Facility is located.

         7.02. Validity and Conflicts. This Agreement is, and all documents to
be executed by Sellers or Alterra pursuant to this Agreement will be, their
valid and binding obligations, enforceable against them in accordance with their
respective terms, except as the enforceability thereof may be limited by
bankruptcy, insolvency, reorganization, moratorium or other similar laws
relating to the enforcement of creditors' rights generally and by general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law). The execution of this Agreement and the
consummation of the transactions contemplated in this Agreement in accordance
with its terms have been approved by all necessary action of Sellers and Alterra
under their respective Charter Documents and do not and will not result in a
breach of the terms and conditions of, nor constitute a default under or
violation of, each Seller's Charter Documents, Alterra's Charter Documents or
any law, regulation, court order, mortgage, note, bond, indenture, agreement,
license or other instrument or obligation to which a Seller or Alterra is now a
party or by which any of Sellers' Assets may be bound or affected.

         7.03. Authority. Sellers and Alterra each have full power and authority
to execute and to deliver this Agreement and all related documents and to carry
out the transactions contemplated herein and therein. Each Seller has full power
and authority (a) to own and operate the Facilities owned by it as the same

         7.04. Financial Statements. Sellers and Alterra have delivered to
Purchaser true and correct copies of the Financial Statements. Except as
otherwise noted in the Financial Statements or on attached Schedule 7.04, the
Financial Statements have been prepared in accordance with GAAP, consistently
applied, and fairly represent the financial condition, and accurately set forth
in all material respects, as and to the extent required by GAAP, the results of
the operations, of Alterra and the Facilities for the periods covered thereby,
subject to customary year end adjustments; provided,


                                       13
<PAGE>   18

however, that the Financial Statements which solely pertain to the Facilities

basis consistent with those of Alterra. Alterra has delivered to Purchaser any
financial statements prepared by Alterra subsequent to the date of the Financial
Statements delivered by it to Purchaser, and such financial statements represent
fairly the financial condition, and set forth accurately in all material
respects the results of the operations, of Alterra and the Facilities for the
periods covered thereby.

notice (i) that any action or proceeding has been initiated or is proposed to be
initiated by the appropriate state or federal agency having jurisdiction
thereof, to revoke, withdraw or suspend any of the Facilities Licenses
applicable to the Completed Facilities or (ii) of any judicial or administrative
agency judgment or decision not to renew any of the Facilities Licenses
applicable to the Completed Facilities or (iii) of any licensure or
certification action of any other type applicable to the Completed Facilities.

         (b) Alterra has applied for all Facilities Licenses applicable to the
Construction Facilities. Attached as Schedule 7.06(b) are true and correct
copies of the license applications filed with the applicable health care
authorities with respect to the operation of the Construction Facilities. To
Sellers' knowledge, upon completion of construction of the Construction

authorities to deny or delay the issuance of the Facilities Licenses for the
Construction Facilities.

         (c) The Completed Facilities are not operated as Medicare or Medicaid
providers, there are no plans to operate the Completed Facilties as Medicare or
Medicaid providers, and the Completed Facilities receive substantially all of

         applicable municipal health and building laws and regulations
         (including, without limitation, the building and life safety codes),
         except to the extent that the failure to comply therewith would not
         have a material adverse effect on the business, property, condition
         (financial or otherwise) or operation thereof;

                  (b) To the best knowledge of Sellers and Alterra, no
         governmental authority having jurisdiction over the Facilities has
         issued any citations with respect to any deficiencies or other matters
         that fail to conform to any applicable statute, regulation, ordinance
         or bylaw and that have not been corrected as of the date hereof or that
         shall not have been corrected on or prior to the Closing, except to the
         extent that either (i) a waiver has been issued by the appropriate
         authority, in which case a copy of such waiver is included in Schedule
         7.07(b), or (ii) the deficiency or non-conformity will not have a
         material and adverse effect on the financial condition or results of
         the operations of such Facility; and

                  (c) To the best knowledge of Sellers and Alterra, none of

         furniture, fixtures, equipment or inventory to be provided at the
         Facilities so as to conform to or comply with any existing and
         applicable law, code or standard, except where the requirement either
         (i) has been fully satisfied prior to the Closing Date, (ii) will, as
         of the Closing Date, be in the process of being satisfied in the
         ordinary course of Sellers' business pursuant to the terms of a plan of
         correction or other documentation submitted to and approved by the
         appropriate authority, (iii) will, as of the Closing Date, be the
         subject of a valid written waiver issued by the applicable licensing or
         certifying agency or (iv) is included in the Construction Budget for
         such Facility if such requirement pertains to a Construction Facility.

         7.08. Residents. Except for notice provisions that are required by law
or that are contained in the Admissions Agreements provided to Purchaser by
Sellers with respect to the Facilities, there are no agreements with residents
of the Facilities that are not terminable by Sellers at will and that require
the owner of the Facilities to provide the care routinely provided at the
Facilities for the duration of the resident's stay at the Facilities for no
consideration.


                                       15

compliance with all applicable requirements and all taxes due with respect to a

disposed of any Hazardous Substances or caused the same to be so released into
the environment or discharged, placed or disposed of at, on or under the
Facilities, except (a) to the extent the same will not have a material and

knowledge of Sellers and Alterra, there is no action pending or recommended by

                  13.02.02. Purchaser's Architect. Purchaser may retain the
services of architects and engineers, including architects and engineers
employed by Purchaser (the "Purchaser's Architect"), to act as Purchaser's agent
in reviewing the Plans and Specifications and the progress of construction and
in making such certifications and performing such other tasks and duties as
Purchaser deems appropriate. Sellers will pay all fees, costs and expenses of
the Purchaser's Architect within ten (10) days after demand by Purchaser;
provided, however, that Sellers will not be obligated to pay for Purchaser's
Architect more than $5,000 per Construction Facility or $40,000 in the
aggregate.

                  13.02.03. Plans and Specifications. Purchaser acknowledges its
approval of the Plans and Specifications. Except as provided below, Sellers will
not make, or cause or permit to be made, any change to the Plans and
Specifications unless a request for the change has been submitted in writing to
Purchaser and approved in writing by the construction manager or general
contractor, as the case may be, any tenants whose approval is required,
Purchaser and such other parties as Purchaser may require. Purchaser's approval
may be subject to such terms and conditions as Purchaser reasonably may
prescribe. Under no circumstances will any failure by Purchaser to respond to a
request for approval of a change in the Plans and Specifications be deemed to
constitute approval of the request. Sellers will deliver promptly to Purchaser
copies of all bulletins, addenda, change orders and modifications to the Plans
and Specifications.

                  Purchaser has the right at all times to require strict
compliance with the original Plans and Specifications, but Sellers may effect
changes in the Plans and Specifications from time to time, without first
obtaining Purchaser's approval, if (i) the changes do not impair the structural
integrity, design concept or architectural appearance of the Construction
Facilities or change the useable area of the Construction Facilities in any way,
(ii) the changes will not result in a default in any other obligation to any
other party or authority and (iii) the changes will not result in a net increase
or decrease in the total Project Costs of FIVE THOUSAND DOLLARS ($5,000) Dollars
or more in the case of any one change or FIFTY THOUSAND DOLLARS ($50,000)
Dollars or more in the aggregate for all changes. Notwithstanding the foregoing,
to the extent that the cost to complete the Construction Facilities exceeds the
Completion Holdback (whether or not as a result of any such changes in the
Plans), Sellers will be responsible for payment of the excess.

                  13.02.04. Character of Construction. All construction will be
in accordance with the Plans and Specifications, of sound materials, in good and
workmanlike manner, free and clear of all liens, claims and encumbrances (other
than the liens and security interests securing the obligations of the Lessee
under the Master Leases), and in compliance with all laws, ordinances,
regulations and restrictions affecting the Construction Facilities and all
requirements of all governmental authorities having jurisdiction over the
Construction Facilities and of the appropriate board of fire underwriters or
other similar body, if any, and any applicable health care authority related to
the Facility Licenses. Sellers will furnish Purchaser with evidence of such
compliance as Purchaser requires from time to time.

which each is retained in connection with the Construction Facilities is
attached as Schedule 13.02.05. Any change to the construction manager(s) or
general contractor(s), as the case may be, and the architect and/or engineer in
connection with the Construction Facilities must be approved by Purchaser in

executed copies of the construction management agreement or general contract(s)
between Sellers and the construction manager or general contractor(s) covering
all work to be done in connection with the Construction Facilities and executed
copies of all subcontracts between the construction manager or general
contractor(s) and all of their subcontractors and suppliers. Upon request of
Purchaser, Sellers will promptly furnish to Purchaser any amendments or
modifications (including change orders) to any of the foregoing. Sellers will
not modify or amend or permit to be modified or amended (including by way of
change order) any construction management agreement, construction contract or
construction subcontract without Purchaser's prior written approval; provided,
however, that Purchaser's prior approval need not be obtained with respect to
any change order that results from a change in the Plans and Specifications with
respect to which Purchaser's consent is not required pursuant to Section
13.02.03 above. Upon request of Purchaser, Sellers will also furnish to
Purchaser an executed copy of the architectural and/or engineering agreement
between Sellers and the architect and/or engineer with respect to the
Construction Facilities.

                  (ii) Sellers will perform their obligations under the
contracts described in subparagraph (i) above, and will use reasonable best
efforts to cause each other party to such contracts to perform its obligations
under such contracts.

                  (iii) Sellers will enforce or cause to be enforced the prompt
performance of the contracts described in subparagraph (i) above and will allow

provision in the Master Leases between Purchaser and Omega-Kansas and Lessee.

                  13.02.07. Access. Notwithstanding anything to the contrary
contained in the Master Leases, Alterra will, and will cause Lessee to, permit
Purchaser's representatives to have access to the Construction Facilities at all
reasonable times and to conduct such investigations and inspections thereof as
Purchaser shall determine necessary, including without limitation in connection
with inspecting the Construction Facilities and all work done, labor performed
and materials furnished in connection with the construction thereof. Alterra
will, and will cause Lessee to, cooperate and cause the construction manager or
general contractor, as the case may be, to cooperate with Purchaser and its
representatives and agents during such inspections. Notwithstanding the
foregoing, Alterra will, and will cause Lessee to, be responsible for making
inspections as to the Construction Facilities during the course of construction
and will determine to their own satisfaction that the work done or materials
supplied by the contractors and subcontractors has been properly supplied or
done in accordance with applicable contracts. All inspections that may be
performed by Purchaser and its agents will be exclusively for the benefit of
Purchaser and will impose no obligation whatever upon Purchaser for the benefit
of any person. Sellers and Alterra will, and will cause Lessee to, hold
Purchaser harmless from, and Purchaser will have no liability or obligation of
any kind to Seller, Alterra, Lessee or creditors of any of them in connection
with, any defective, improper or inadequate workmanship or materials brought in
or related to the Construction Facilities, or any construction lien arising as a
result of such workmanship or materials. No inspection by Purchaser will create
any obligation on Purchaser or relieve Sellers, Alterra or Lessee of any
obligation.

                  13.02.08. Damage by Fire or Other Casualty. If any of the
Construction Facilities is partially or totally damaged or destroyed by fire or
other casualty or taken under the power of eminent domain, proceeds of such
event will be applied as provided in the Master Leases.

                  13.02.09. Payment of Costs. Sellers or Alterra will pay when
due all obligations incurred by Sellers, Alterra or Lessee for the Construction
Facilities, including any cost for restoration incurred pursuant to paragraph
13.02.08 above.

                           exceptions than are set forth on the Title Policies
                           delivered to Purchaser at closing; and

                  (3)      The Escrow Agent has not received from Purchaser,
                           within five (5) Business Days after receipt of the
                           items described in subparagraph (a) above, written
                           notice from Purchaser disputing the matters set forth

                           above.

         13.04. Limitation on Disbursements. In no event will the Escrow Agent
pay amounts in excess of the amounts actually paid out by Sellers for services
or materials incorporated into the Construction Facilities.

         13.05. Sufficiency of Completion Holdback. Purchaser shall be entitled
to instruct the Escrow Agent not to make a disbursement or instruct the Escrow
Agent to make a disbursement in an amount less than the amount requested) if

construction of the Construction Facilities will be at least equal to the sum of
(a) the estimated Soft Costs to complete the Construction Facilities in
accordance with the Plans and Specifications (including all costs in connection
with changes in the Plans and Specifications) and (b) 110% of the estimated Hard
Costs to complete the Construction Facilities in accordance with the Plans and
Specifications (including all costs incurred in connection with changes in the
Plans and Specifications). If at any time it appears to Purchaser that the
unpaid balance of the Completion Holdback is less than the amount required by
this Section, Purchaser may give written notice to Sellers specifying the amount
of the deficiency and Sellers immediately will deposit with Escrow

Agent the amount of the deficiency, which will be expended first in the same
manner as Completion Holdback before any further payment of the Completion
Holdback will be made by Purchaser. Purchaser may determine the cost of
construction of the Construction Facilities and Sellers will be obligated to pay
any sums so determined in excess of the Completion Holdback prior to any payment
under this Agreement.

         13.06. Payments to Contractor, Subcontractors and Suppliers. In order
to induce the Escrow Agent to insure Purchaser's title to the Construction
Facilities without exception for the construction or mechanics' liens, the
Escrow Agent may make payments directly to any contractor, subcontractor or
supplier furnishing labor or materials to the Construction Facilities.

         13.07. Purchaser's Right to Cure. If Sellers or Alterra fail to perform

Purchaser any amounts expended by Purchaser in so doing. In addition to the
foregoing, Purchaser may make require the Escrow Agent to pay the Completion
Holdback to Purchaser in payment of rent and other charges due under the Master
Leases without regard to whether such payments have been approved by Sellers.

         13.08. Application of Advances. Sellers will apply each payment of
Completion Holdback against amounts due and payable for construction of the
Construction Facilities or obligations in connection therewith. Nothing
contained in this Agreement will impose upon Purchaser any obligation to see to
the proper application of the advances by Sellers or any other party.

         13.09. Construction or Other Liens. In the event any construction or
other lien or encumbrance is filed or attached against the Construction
Facilities or any part thereof without the prior written consent of Purchaser,
Purchaser may, at its option and without regard to the priority of such
construction or other lien or encumbrance, and without regard to any defenses
that Sellers may have with respect to the lien or encumbrance, pay the same, and
Sellers and Alterra, jointly and severally, will reimburse all amounts expended
by Purchaser for such purpose within ten (10) days of written notice thereof.

         13.10. Conditions to Final Payment. Purchaser shall be entitled to

Holdback from the Completion Escrow unless and until all of the following
conditions have been fulfilled to Purchaser's satisfaction:

                                    complete the work covered by the Plans and
                                    Specifications;

         14.01 Guaranty of Completion. Subject to a temporary suspension of
performance pursuant to Section 14.02, but regardless of whether the cost
thereof exceeds the amount of the Completion Holdback, Sellers and Alterra will
diligently and continuously carry out or cause to be carried out the
construction of the Construction Facilities so as to insure the completion of
construction of the Construction Facilities, the opening of the Construction
Facilities and the acquisition of all Facilities Licenses for the Construction
Facilities, all by the applicable Completion Date. Regardless of whether the
cost thereof exceeds the amount of the Completion Holdback, Sellers and Alterra
will be responsible for payment of all costs of completing, opening and
licensing the Construction Facilities, including the payment of all costs in
excess of the Construction Budgets. Sellers and Alterra promptly will correct
any structural defects in the Construction Facilities or any departure from the
Plans and Specifications not previously approved by Purchaser. The approval or
absence of disapproval by Purchaser of any payment of Completion Holdback from
the Completion Escrow shall not constitute a waiver of Purchaser's right to
require compliance with this Article XIV.

         14.02 Force Majeure. Upon the occurrence and during the continuance of
an Event of Force Majeure and the giving of written notice thereof to Purchaser,
Sellers and Alterra shall be

their obligations under Article XIII and Section 14.01, except for the
obligation to pay any amounts due and owing thereunder, but only to the extent
and only for the period that their performance of each such obligation is
prevented by the Event of Force Majeure. Such notice shall include a description
of the nature of the Event of Force Majeure, and its cause and possible
consequences. Sellers and Alterra shall promptly notify Purchaser of the
termination of such event. Upon the request of Purchaser, Sellers and Alterra
shall provide confirmation of the existence of the circumstances constituting an
Event of Force Majeure. Such evidence may consist of a statement of an
appropriate governmental department or agency where available, or a statement
describing in detail the facts claimed to constitute an Event of Force Majeure.
During the period that the performance by Sellers and Alterra has been suspended
by reason of an Event of Force Majeure, Purchaser may likewise suspend the
performance of all or part of its obligations under this Agreement to the extent
that such suspension is commercially reasonable and, notwithstanding anything in
this Agreement to the contrary, Escrow Agent shall make no disbursements from
the Construction Account.

         Date;

                  (b) Any misrepresentation of a material fact, breach of
         warranty or nonfulfillment of any agreement on the part of Sellers or
         Alterra under this Agreement or from any misrepresentations in any
         certificate furnished or to be furnished to Purchaser hereunder;

                  (c) Any failure by Sellers or Alterra in connection with the
         transaction contemplated herein to comply with the requirements of any
         laws or regulations relating to bulk sales or transfers; and

For purposes of Section 15.01(a), an obligation shall be deemed to "exist"
immediately prior to the Closing Date if it relates to events that occurred
prior to the Closing Date even if it is not asserted until after the Closing
Date.

         15.02. Procedure. If an Indemnified Party asserts that the Indemnitors
are subject to a Claim for indemnification pursuant to Section 15.01, the
Indemnified Party promptly shall notify the Indemnitors in writing of the Claim
and shall describe in the notice the Claim in sufficient detail in order to
permit the Indemnitors to evaluate the nature and cause of the Claim. If the
asserted Claim arises or is in connection with a claim, suit or demand filed by
a third party, the Indemnitors shall be entitled to defend against the Claim
with counsel reasonably satisfactory to the Indemnified Party. The Indemnified
Party may continue to employ counsel of its own, but such costs shall be borne
by the Indemnified Party as long as the Indemnitor continues to so defend. If
the Indemnitors fail to respond or does not admit responsibility for
indemnification, the Indemnified Party may take such necessary steps to defend
itself and any reasonable costs associated therewith may be included as part of
the asserted Claim for indemnification. For all Claims that are not Claims
arising from a third party, the Indemnitors shall notify the Indemnified Party
as to its assertion of whether the Claim is covered by this Article, including
specific reasons for non-coverage, within 30 days of receipt of written notice
from the Indemnified Party describing the Claim in reasonable detail.

party to arbitration. The Section shall not apply to any controversy that may
