                            RIGHT OF FIRST REFUSAL 

         This RIGHT OF FIRST REFUSAL  (the "Agreement") dated as of December 1,
1995, is made and entered into by and between NHP-HDV Four, Inc., NHP-HDV Five,
Inc., NHP-HDV Six, Inc., NHP-HDV Seven, Inc. and NHP-HDV Eight, Inc., all
Delaware corporations (hereinafter collectively referred to as "Holders") and
NHP INCORPORATED, a Delaware corporation (hereinafter referred to as "NHPI").

                                   RECITALS:

        A.       Holders are the holders of the general partner interests
("Partnership Interests") and stock ("Stock") of the general partners of the
limited partnerships set forth on Exhibit A beside the name of the applicable
Holder, each of which limited partnership is the owner of a real estate project
(the "Properties"), set forth on Exhibit B attached hereto and incorporated
herein by reference.

        B.       NHP Management Company ("NHPMC"), a wholly-owned subsidiary of
NHPI, is the property manager of each of the Properties (hereinafter referred
to as the "Management Rights").

        C.       NHPMC is in the business of property management and wishes to
retain the Management Rights in the event that any or all of the Holders sell
or otherwise convey the Stock, Partnership Interests or the Properties.

        D.       Subject to, and upon the terms and conditions set forth in
this Agreement, NHPI has requested and Holders have agreed to grant to NHPI a
right of first refusal with respect to the Stock, the Partnership Interests and
the Properties.

                                   AGREEMENT:

        NOW, THEREFORE, for and in consideration of the above-recited premises,
the mutual covenants and agreements hereinafter set forth and other good and
valuable consideration, the receipt, adequacy, and sufficiency of which are
hereby acknowledged and confessed, the parties hereto do hereby covenant and
agree as follows:

        1.       Subsequent Transfers by Holders.  In the event any Holder
elects to sell any of the Stock or Partnership Interests or to dispose of any
of the Properties (a "Disposition"), such Holder shall provide NHPI with
written notice of such election.  NHPI shall then have the option during the
thirty (30)-day period following receipt of such notice, to acquire the Stock,
Partnership Interests or the Properties identified in said notice, at no cost.
In the event NHPI does not exercise the heretofore described option, such
Holder may sell any or all of the Stock, Partnership Interests or dispose of
any or all of the Properties, subject to the following:  Each Holder covenants
and agrees (which agreement shall survive the Closing) to pay to NHPI (i) for
each of the Stock, Partnership Interests or Properties sold, where such sale
results in NHPI or any of its subsidiaries losing the right to manage the
subject Property, a one-time termination fee equal to the lesser of (x) two
hundred percent (200%) of the total amount of fee income earned by NHPI and any
of its susidiaries during the twelve-month period ending on the last day of the
month prior to the month in which a Disposition occurs; or (y) the Holder's
share of





                                      -1-

the sales proceeds; and (ii) the sum of $8,000 per annum for each of the
Properties, the Stock or Partnership Interests so disposed; provided, however,
no payment shall be due under this Paragraph 1 in the event NHPI or any of its
subsidiaries is terminated as management agent for such Property for cause.

        2.       Representations and Warranties of NHPI.  The NHPI hereby
represents and warrants to Holders that:

                 (a)      NHPI is a Delaware corporation duly organized,
         validly existing and in good standing under the laws of the state of
         Delaware;

                 (b)      NHPI has full power, authority and legal right to
         execute and deliver this Agreement, has and will have full power,
         authority and legal right to perform and observe its provisions and
         this Agreement is valid, binding and enforceable against NHPI in
         accordance with its terms.

         3.      Representations and Warranties of Holders.  Each Holder
represents and warrants to NHPI that:

                 (a)      Each Holder is a Delaware corporation duly organized,
         validly existing and in good standing under the laws of the Delaware;

                 (b)      Each Holder has full power, authority and legal right
         to execute and deliver this Agreement and to perform and observe its
         provisions and this Agreement when executed and delivered by NHPI and
         Holders will be valid, binding and enforceable against Holders in
         accordance with its terms.

         4.      Remedies.  If either party defaults hereunder, the
non-defaulting party may sue the defaulting party for damages.

         5.      Notices.  Unless otherwise specifically provided herein, any
notice or communication required or permitted to be delivered hereunder shall
be in writing and shall be deemed to have been given upon the earlier to occur
