          interest earned thereon from and after the Last Closing Date) as
          directed in such demand (or, if no directions are given in such demand
          regarding the Deposit, disburse the Deposit and all such interest to
          Buyer), disburse the undisbursed interest earned on the Deposit before
          the Last Closing Date to Buyer and return every other item deposited

          actions with respect to Escrow (other than to continue to invest and
          reinvest the Deposit as provided in Section 2.1.1) except (A) in

          Escrow Agent's legal counsel, in accordance with a certified copy of
          the order or judgment of any court; provided, however, that if Seller
          and Buyer have not provided Escrow Agent with joint written
          instructions as to the disposition of Escrow (and all items deposited
          therein) within 60 days after Escrow Agent's receipt of such demand
          for cancellation, Escrow Agent shall have the right (at any time
          thereafter) to commence an action in interpleader against Seller and
          Buyer and, in connection therewith, to deposit all funds and other
          items held in Escrow with the court hearing such action, whereupon
          Escrow Agent shall be relieved of all further obligations and duties
          with respect to Escrow. Buyer and Seller, jointly and severally, shall
          hold harmless and indemnify Escrow Agent from and against any costs

writing as to whether the Title Policy is to be issued as an ALTA owner's
extended coverage policy or as a binder (effective for at least 24 months) for

cause the Title Company to issue the Title Policy in the form of an ALTA owner's
extended coverage policy.

          2.10 Supplemental Escrow Agreement. Buyer and Seller shall execute
such supplemental escrow instructions or supplemental escrow agreement as Escrow

         other real property is now being used in conjunction with the operation
         or occupancy of the Property.

                conveyance thereof or would or purport to bind any successor of

or any of the Property is bound.

                             (xvii) Seller has not filed notices of protest
against, or commenced proceedings to review, real property tax assessments
against the Real Property; nor does Seller currently contemplate the filing of

contemplated herein; all liabilities which arise as a result of Seller's
employment of any persons at the Property shall have been satisfied as of

                    encumbering the Real Property, other than in the ordinary
                    course of business and consistent with Seller's prior and
                    current business practices, without Buyer's prior written
                    consent, which Buyer shall not unreasonably withhold or

                                      (B) Do anything else which would impair

          under the ground) as Buyer may reasonably require; provided, however,
          that Buyer shall give Seller specific advance notice of any soil
          borings or sampling and obtain Seller's prior approval (which Seller
          shall not unreasonably withhold or delay) and that Seller may have an
          authorized representative accompany Buyer's contractor during the
          taking of such borings or samples.

          basis for such claim, before the eighteenth (18) month anniversary of
          the Closing Date.

                          (ii) Buyer shall not have any liability to Seller

<PAGE>

the Property is damaged, destroyed or taken by eminent domain (a "Casualty"),
Buyer shall have the right, at its election, either to:

                          (i)  Terminate this Agreement without liability; or

                          (ii) Continue this Agreement, in which case Buyer
          shall be entitled to all insurance proceeds, condemnation awards or
          other amounts which have been paid or may thereafter be payable to
          Seller by any person in connection with such damage, destruction or
          taking ("Proceeds"), and at Closing Seller shall pay to Buyer the
          amount of any Proceeds already received by Seller, shall assign Buyer
          all of Seller's rights to Proceeds which may then be or thereafter
          become payable, and shall pay to Buyer an amount equal to the per
          occurrence deductible amount under the applicable casualty insurance
          policy.

For purposes of this Section, a Casualty shall be deemed to affect a material
part of the Property if: (A) such Casualty results in the taking or other
permanent loss of more than five (5) rentable recreational vehicles or five (5)
boat slips (B) such Casualty results in damage to the Property which, in Buyer's
reasonable estimation, will cost more than $150,000 or require more than 30 days
to repair or replace. If a Casualty occurs fewer than 30 days before the Last
Closing Date, Buyer shall have the right to extend the Last Closing Date until
the 30th day after the occurrence of such Casualty in order to make the election
permitted by this Section.

3.7                 Assignment by Buyer. Prior to Closing, Buyer shall have the
                    right to assign or transfer its rights under this Agreement
                    to (i) any investor client of Buyer or to any trust or
                    title-holding corporation for the benefit of such a client
                    or (ii) any Affiliate (defined below) or any partnership
                    with respect to which an Affiliate is liable as a general
                    partner (either directly or through the general partnership
                    interest in one or more sub-tier partnerships), provided
                    that such assignee concurrently with such assignment
                    assumes, in a written instrument delivered to Seller, all of
                    the obligations and liabilities of Buyer hereunder. Upon
                    such an assignment, the assignee shall become the Buyer for
                    all purposes of this Agreement and the Buyer named herein
                    shall be relived of any further obligation or liability
                    hereunder (but without impairment of Seller's rights to
                    liquidated damages under Section 3.8). As used herein,
                    "Affiliate" means Buyer or any other corporation or legal
                    entity which, directly or indirectly, has the same ultimate
                    beneficial ownership as Buyer. Nothing herein shall be
                    deemed to preclude or prevent Buyer, after Closing, from
                    assigning any of its remaining rights under this Agreement,
                    pro tanto, in conjunction with any sale, lease, secured
                    financing or other conveyance of any of the Real Property or
                    any possessory or security interest therein.

3.8                 Liquidated Damages. IF BUYER BREACHES ITS OBLIGATION UNDER
                    THIS AGREEMENT TO PURCHASE THE PROPERTY, SELLER, AS ITS SOLE
                    AND EXCLUSIVE REMEDY ON ACCOUNT OF SUCH BREACH, SHALL
                    RECEIVE AND RETAIN, AS LIQUIDATED DAMAGES, THE DEPOSIT
                    (TOGETHER WITH ALL INTEREST EARNED ON THE DEPOSIT FROM AND
                    AFTER THE LAST CLOSING DATE). BUYER AND SELLER ACKNOWLEDGE
                    THAT SUCH LIQUIDATED DAMAGES ARE REASONABLE IN AMOUNT
                    CONSIDERING ALL OF THE CIRCUMSTANCES EXISTING ON THE DATE OF
                    THIS AGREEMENT, INCLUDING THE PARTIES' ESTIMATION OF THE
                    POSSIBLE RANGE OF DAMAGES TO SELLER IN THE

                    EVENT OF SUCH A BREACH, THE DIFFICULTY AND IMPRACTICABILITY
                    OF ASCERTAINING OR PROVING WITH ANY DEGREE OF CERTAINTY THE
                    AMOUNT OF SUCH DAMAGES AND THE DESIRE OF BUYER TO LIMIT ITS
                    POTENTIAL LIABILITY TO SELLER IN THE EVENT OF SUCH A BREACH.
                    BY INITIALING THIS PROVISION IN THE SPACES BELOW, SELLER AND
                    BUYER EACH SPECifICALLY AFFIRM THEIR RESPECTIVE AGREEMENTS
                    IN THIS SECTION.

3.9       Termination.

                    3.9.1 By Buyer. If Buyer has and timely exercises any right
hereunder to terminate this Agreement (or if this Agreement terminates because
Buyer fails to give notice of satisfaction of the Due Diligence Condition or
client approval, as required under Section 2.4), Buyer shall be immediately
entitled to the return of the Deposit and all undisbursed interest earned
thereon while in Escrow and, promptly upon receiving notice of such termination,
Seller shall join with Buyer in a written notice to Escrow Agent acknowledging
the termination of this Agreement and instructing Escrow Agent to return the
Deposit (together with all undisbursed interest earned thereon while in Escrow)
to Buyer and to return every other item deposited in Escrow to the Party which
deposited the same.

                    3.9.2 By Seller. If Seller has and exercises any right
hereunder to terminate this Agreement for a breach by Buyer of its obligation to
purchase the Property hereunder, promptly upon receiving notice of such
termination Buyer shall join with Seller in a written notice to Escrow Agent
acknowledging the termination of this Agreement and instructing the Title
Company to deliver the Deposit to Seller, to disburse all interest earned on the
Deposit from and after the Last Closing Date to Seller and all interest earned
on the Deposit before the Last Closing Date to Buyer, and to return every other
item deposited in Escrow to the Party which deposited the same. If Seller
terminates this Agreement for any other reason, Seller shall promptly, upon
Buyer's written request, join with Buyer in a written notice to Escrow Agent
acknowledging the termination of this Agreement and instructing Escrow Agent to
return the Deposit (together with all undisbursed interest earned thereon while
in Escrow) to Buyer and to return every other item deposited in Escrow to the
Party which deposited the same.

                    3.9.3 Effect of Termination. Upon any termination of this
Agreement, neither Party shall have any further obligation or liability to the
other hereunder except (i) any remaining obligation or liability of Buyer under
Section 3.1 (for return of documents to Seller) or under Section 3.5.2 (with
respect to activities of Buyer or its agents upon the Real Property), (ii) any
liability which either Party may have hereunder by reason of the fact that such
termination either (A) was wrongfully made by it or (B) resulted from a breach
of its warranties, covenants or other obligations hereunder and (iii) any
obligation under Section 3.11.

          3.10 Brokerage Fees. Upon Closing, Seller shall pay to Broker a
commission equal to two percent (2%) of the Purchase Price to be shared equally
by NHC Sales of Arizona, Inc. and Devine Real Estate, Inc., and shall hold
harmless, indemnify and defend Buyer from and against any claim by or liability
to Broker for any commission, fee or other compensation with respect to the
transactions contemplated by this Agreement. Nothing contained herein shall be
deemed to make Broker a third-party beneficiary of this Agreement or to create
any obligation on the part of either Party to close the sale and purchase of the
Property for Brokerst benefit.

          3.11 Enforcement Costs. Should either Party institute any action or
proceeding to enforce any provision of this Agreement or for damages by reason
of an alleged breach of any provision hereof, the prevailing Party shall be
entitled to receive all costs and expenses (including reasonable attorneys'
fees) incurred by such prevailing Party in connection with such action or
proceeding. A "prevailing Party" includes one who dismisses an action brought
under or with respect to this Agreement in exchange for the

                                       19
<PAGE>

payment of the sums alleged to be due, performance of the covenants alleged to
have been breached or other consideration substantially equal to that sought in
such action. A Party entitled to recover costs and expenses under this Section
shall also be entitled to recover all costs and expenses (including reasonable
attorneys' fees) incurred in the enforcement of any judgement or settlement
obtained in such action or proceeding (and in any such judgement provision shall
be made for the recovery of such post judgement costs and expenses).

          3.12 Notices. Except in the case (if any) where this Agreement
expressly provides for an alternate form of communication, any notice, consent,
demand or other communication to be delivered to a Party hereunder shall be
