STATEMENT REGARDING FORWARD LOOKING DISCLOSURE

     Certain information contained in this report includes forward looking 
statements, which can be identified by the use of forward looking terminology 
such as "may", "will", "expect", "should" or comparable terms or the negative 
thereof. These statements involve risks and uncertainties that could cause
actual results to differ materially from those described in the statements.
These risks and uncertainties include (without limitation) the following: the 
effect of economic and market conditions and changes in interest rates, 
government regulations, including changes in Medicare and Medicaid payment 
levels, changes in the health industry, the amount of any additional 
investments, access to capital markets and changes in the ratings of the 
Company's debt securities.
 
ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

On September 24, 1997, Nationwide Health Properties, Inc. ("the Company") 
acquired from unrelated parties two continuing care retirement communities, two 
assisted living facilities and one long-term health care facility ("the Laureate
Properties") in a related transaction at an aggregate negotiated purchase price 
of $96,000,000.  The facilities were concurrently leased back on a triple net 
basis to the Laureate Group which developed, built and had operated these 
facilities prior to their acquisition by the Company under terms generally 
similar to the Company's existing leases.  The purchase price consisted of 
approximately $39,739,000 of debt assumption, approximately $25,756,000 of cash 
and 1,315,686 shares of the Company's common stock.  The cash portion of the 
purchase price was funded by bank borrowings on the Company's revolving bank 
line of credit with Wells Fargo Bank, National Association, Sanwa Bank 
California, The Sumitomo Bank, Limited, BHF-Bank Aktiengeselllschaft and The 
Bank of New York and cash on hand.

The acquisition of the facilities was effectuated through (i) the mergers of
Laureate Investments, Inc. and Laureate Properties, Inc. into wholly-owned
subsidiaries of NHP and (ii) the purchase of certain limited partnership
interests from six individuals. The assets acquired by virtue of these
transactions generally include all of the partnership interests in nine limited
partnerships that own the real property of the facilities acquired. The Company
has agreed to register the shares of the Company's common stock issued in
connection with the mergers for resale under the Securities Act of 1933, as
amended, in certain circumstances pursuant to a registration rights agreement.

     The Company believes these acquisitions are consistent with the Company's 
historical business strategy of acquiring and concurrently net leasing health 
care facilities to qualified operators.  In assessing the facilities, the 
Company considered the type, location, age, design and physical condition of the
facilities acquired, as well as any historical and projected operating results
of the health care operations conducted at the facilities. Additionally, the
Company considers the operating ability, financial condition and reputation of
the operator to which the acquired facilities are to be leased. The Company,
after reasonable inquiry, is not aware of any material factors that would cause
the financial information reported not to be necessarily indicative of future
operating results. The Company intends to continue the current use of each
property.
 
     Certain audited pro forma financial information concerning these properties
is provided in Item 7 of this Current Report on Form 8-K.

ITEM 5.  OTHER EVENTS

     In addition to the transaction described in Item 2 of this Report on Form 
8-K, during the period from August 5, 1997 through October 1, 1997, NHP acquired
from unrelated parties four assisted living facilities ("ALF") and one long-term
health care facility ("SNF") in five separate transactions at an aggregate 
purchase price of approximately $16,879,000 ("the Other Facilities").  The 
facilities were, concurrently with their acquisition, leased on a triple net 
lease basis to two different operators under terms generally similar to the 
Company's existing leases.  Each transaction, with the exception of Andover 
Court, was funded by bank borrowings on the Company's revolving bank line of 
credit and by cash on hand.  Andover Court was funded by the assumption of 
$2,800,000 of debt, by bank borrowings on the Company's revolving bank line of 
credit and cash on hand.

     Although no single acquisition is considered a "significant acquisition" 
pursuant to the rules governing the reporting of transactions on Form 8-K, under
Rule 3-14 of Regulation S-X, these acquisitions in the aggregate when combined 
with the acquisitions described in the Company's Current Report on Form 8-K 
dated August 18, 1997, may be considered to be material in nature.  Certain 
audited pro forma financial information concerning these properties is provided 
in Item 7 of this Current Report on Form 8-K.

ITEM 7.  FINANCIAL STATEMENTS AND EXHIBITS
- ------   ---------------------------------

         Financial information for the health care operations of the acquired 
facilities is not presented because the related operating information for such 
facilities, after exclusion of items not comparable to the proposed net leased 
real estate operations by the Company pursuant to Rule 3-14 of Regulation S-X, 
would not be meaningful.  Alternatively, the Company has presented audited pro 
forma operating information for each of the acquired properties described in
Items 2 and 5 of this report as if the acquired properties had been owned and
net leased by the Company since January 1, 1996.

                 REPORT OF THE INDEPENDENT PUBLIC ACCOUNTANTS


TO THE STOCKHOLDERS AND DIRECTORS, NATIONWIDE HEALTH PROPERTIES, INC:

We have examined the pro forma adjustments reflecting the transactions described
in Note 1 and the application of those adjustments to the assembly of the
accompanying pro forma statements of income of the properties acquired by 
Nationwide Health Properties, Inc. during the period August 5, 1997 to October
1, 1997 as indicated in Items 2 and 5 of this Form 8-K (collectively "the
Acquired Properties") for the year ended December 31, 1996. The historical
statements of income are omitted since substantially all historical amounts are
not relevant on a pro forma basis and in some cases, the facilities were opened
in 1997. The pro forma adjustments are based upon management's assumptions
described in Note 2. Our examination was made in accordance with standards
established by the American Institute of Certified Public Accountants and,
accordingly, included such procedures as we considered necessary in the
circumstances.

The objective of this pro forma financial information is to show what the 
significant effects on the historical financial information might have been had 
the transactions occurred at an earlier date.  However, the pro forma statements
of income are not necessarily indicative of the results of operations that would
have been attained had the above-mentioned transactions actually occurred 
earlier.

In our opinion, management's assumptions provide a reasonable basis for 
presenting the significant effects directly attributable to the above-mentioned 
transactions described in Note 1, the related pro forma adjustments give 
appropriate effect to those assumptions, and the pro forma statements of income 
for the year ended December 31, 1996 reflect the proper application of those 
adjustments to the historical statement of income amounts.

FOOTNOTES TO PRO FORMA STATEMENTS OF INCOME


NOTE 1: Nationwide Health Properties, Inc. (the "Company") acquired 6 assisted
living facilities, 2 Continuing Care Retirement Communities and 2 long-term
health care facilities in 6 separate transactions at an aggregate purchase price
of approximately $112,879,000. The facilities were leased to 3 different
operators under terms generally similar to the Company's existing leases. The
facilities are leased under "net" leases which are accounted for as operating
leases. The leases have initial terms of 10 to 17 years. The Company earns fixed
monthly minimum rent and may earn periodic additional rents. The additional
payments are generally computed based upon increases in the Consumer Price Index
or as a percentage of facility net patient revenues in excess of base amounts.
Additional rents generally commence in the second year of the leases. Under
terms of the leases, the lessees are responsible for all maintenance, repairs,
taxes and insurance on the leased properties.

The pro forma statements of income reflect the acquisitions of the properties as
if they had been owned since January 1, 1996.

NOTE 2: Pro forma minimum rents are based upon the monthly minimum rents
specified in the leases. No additional rent amounts are assumed for purposes of
the pro forma statements of income based upon the terms of the lease.

Pro forma depreciation is based upon the purchase prices of the facilities being
allocated to building and depreciated over 40 years. 

Pro forma interest expense with respect to the Laureate Properties is based upon
allocating the Company's weighted average borrowing on the Company's 1997 medium
term note issuances and its June 30, 1997 cost on its unsecured revolving line
of credit applied against the cash portion of the purchase price, approximately
$25,756,000, and the actual interest expense expected to be incurred on the debt
assumed as part of the purchase, approximately $39,739,000. The weighted average
interest rate on such debt is 7.22%. The balance of the purchase price of the
Laureate properties was paid by the issuance of 1,315,686 shares of the
Company's common stock and no pro forma interest expense is assumed for such
portion of the purchase price.

Pro forma interest expense, for the properties other than the Laureate
Properties and Andover Court, is based upon allocating the Company's weighted
average borrowing on the Company's 1997 medium term note issuances and its June
30, 1997 cost on its unsecured revolving line of credit applied against the
aggregate purchase prices. Such weighted average rate was 6.97%. Pro forma 
interest expense for Andover Court is based upon applying the weighted average 
interest rate of 9.73% on the $2,800,000 of assumed indebtedness and upon 
allocating the 6.97% weighted interest rate described above to the $1,000,000 
cash portion of the purchase price.

The Company's unsecured line of credit matures on May 31, 2000. The Company
anticipates repaying such line of credit borrowings at some time in the future
prior to its current maturity with proceeds from public offerings or private
placements of long-term unsecured debt or equity. Accordingly, the actual
interest expense resulting from the acquisitions of the facilities may vary.

No pro forma general and administrative costs are included because:  (1) such 
amounts are expected to be immaterial, and (2) the Company does not expect to 
add additional staff as a result of the transactions described in Note 1 above.

NOTE 3:  The preparation of financial statements requires management to make 
estimates and assumptions that affect the revenues and expenses during the 
reporting period.  Actual results could differ from those estimates.

                        PRO FORMA FINANCIAL INFORMATION


     The following unaudited Pro Forma Balance Sheet as of June 30, 1996 and 
unaudited Pro Forma Statements of Operations for the six months ended June 30,
1997 and for the year ended December 31, 1996 have been prepared to reflect the
acquisition of (i) the Laureate Properties described in Item 2 of this Form 8-K,
(ii) the other facilities described in Item 5 of this Form 8-K (the "Other
Facilities") and (iii) the 26 facilities acquired during the period from
January 1, 1997 through August 4, 1997 (the "Acquired Facilities") as described
in the Company's Current Report on Form 8-K dated August 18, 1997 and the
adjustments described in the accompanying notes. The pro forma financial
information is based on the historical financial statements of Nationwide Health
Properties, Inc. in the Company's Form 10-Q for the period ended June 30, 1997
and the other financial information in the Company's 1996 Annual Report on Form
10-K, and should be read in conjunction with those financial statements and the
notes thereto.

     The Pro Forma Balance Sheet was prepared as if the Laureate Properties, the
Other Facilities and the Acquired Facilities were purchased on June 30, 1997.
The Pro Forma Statements of Operations were prepared as if the Laureate
Properties, the Other Facilities and the Acquired Facilities were purchased as
of January 1, 1996.

     The combined pro forma financial information is not necessarily indicative 
of the financial position or results of operations which actually would have 
occurred if such transactions had been consummated on the dates described, nor 
does it purport to represent the Company's future financial position or results 
of operations.

term health care facilities and one clinic in 20 separate transactions at an
aggregate purchase price of approximately $94,969,000 (the "Acquired
Properties"). The Acquired Properties were leased to six different operators
under terms generally similar to the Company's existing leases. On September 24,
1997, the Company acquired 2 continuing care retirements communities, two 
assisted living facilities and 1 long-term health care facility (the "Laureate 
Properties") in a related transaction at an aggregate purchase price of 
$96,000,000. The Laureate Properties were leased to one operator under terms 
generally similar to the Company's existing leases. Between August 5, 1997 and 
October 1, 1997, the Company acquired 4 assisted living facilities and 1 
long-term health care facility (the "Other Facilities") in 5 separate 
transactions at an aggregate purchase price of approximately $16,879,000. The 
Other Properties were leased to two operators under terms generally similar to 
the Company's existing leases.

The facilities are leased under "net" leases which are accounted for as
operating leases. The leases have initial terms of 9 to 17 years. The Company
earns fixed monthly minimum rent and may earn periodic additional rents. The
additional payments are generally computed based upon increases in the Consumer
Price Index or as a percentage of facility net patient revenues in excess of
base amounts. Additional rents generally commence in the second year of the
leases. Under terms of the leases, the lessees are responsible for all
maintenance, repairs, taxes and insurance on the leased properties.

The pro forma statements of operations reflect the acquisitions of the 
properties as if they had been owned since January 1, 1996, and the pro forma 
balance sheet reflects the acquisition of the properties as if they had been 
owned on June 30, 1997.

NOTE 2:  The pro forma balance sheet adjustments reflect the allocation between
land and building and improvements of the $42,992,000 of the Acquired Properties
purchased after June 30, 1997 and the increase in bank borrowings and a medium
term note issuance used to fund the purchase. No adjustment has been made to
accumulated depreciation for those properties acquired prior to June 30, 1997. 
The balance sheet adjustments also reflect the allocation between land and 
building and improvements of the Laureate Properties and Other Facilities. The 
Laureate Properties adjustments reflect the assumption of approximately 
$39,739,000 of debt, the issuance of 1,315,686 shares of the Company's common 
stock and an increase in bank borrowings to fund the cash portion, approximately
$25,756,000, of the $96,000,000 purchase price. The Other Facilities adjustments
reflect an increase in bank borrowings to fund the cash portion of the aggregate
purchase price as well as the assumption of $2,800,000 of debt. Reductions of
cash reflect payment of miscellaneous closing costs.

NOTE 3:  The pro forma minimum rent adjustment is based upon the monthly minimum
rents specified in the leases.  No additional rent amounts are assumed for 
purposes of the pro forma statements of income based upon the terms of the 
lease.

The pro forma depreciation adjustment is based upon the purchase prices of the 
facilities being allocated to building and depreciated over 30 to 40 year lives.

The pro forma interest expense adjustment with respect to the Acquired
Properties is based upon allocating the Company's weighted average borrowing on
the Company's 1997 medium term note issuances through August 18, 1997 and its
June 30, 1997 cost on its unsecured revolving line of credit applied against the
aggregate purchase prices. Such weighted average rate was 6.99%. Pro forma
interest expense with respect to the Laureate Properties is based upon
allocating the Company's weighted average borrowing on the Company's 1997 medium
term note issuances and its June 30, 1997 cost on its unsecured revolving line
of credit, 6.97%, applied against the cash portion of the purchase price,
approximately $25,756,000, and the actual interest expense expected to be
incurred on the debt assumed as part of the purchase, approximately $39,739,000.
The weighted average interest rate on such debt is 7.22%. The balance of the
purchase price of the Laureate Properties was paid by the issuance of 1,315,686
shares of the Company's common stock and no pro forma interest expense is
assumed for such portion of the purchase price.

Pro forma interest expense with respect to the Other Facilities is based upon 
allocating the Company's weighted average borrowing on the Company's 1997 medium
term note issuances and its June 30, 1997 cost on its unsecured revolving line 
of credit, 6.97%, applied against the cash portion of the purchase price, 
approximately $14,079,000, and the actual interest expense expected to be 
incurred on the debt assumed as part of the purchase, approximately $2,800,000. 
The weighted average interest rate on such debt is 9.73%.

The Company's unsecured line of credit matures on May 31, 2000. The Company
anticipates repaying such line of credit borrowings at some time in the future
prior to its current maturity with proceeds from public offerings or private
placements of long-term unsecured debt or equity. Accordingly, the actual
interest expense resulting from the acquisitions of the facilities may vary.

<PAGE>
 
No pro forma general and administrative costs are included because: (1) such 
amounts are expected to be immaterial, and (2) the Company does not expect to 
add additional staff as a result of the transactions described in Note 1 above.

NOTE 4: The preparation of financial statements requires management to make 
estimates and assumptions that affect the revenues and expenses during the 
reporting period. Actual results could differ from those estimates.

        3.10  Waiver of Conditions.  Any party may at any time or times, in its
              --------------------                                             
sole discretion, waive any of the conditions to its obligations hereunder, but
any such waiver shall be effective only if contained in a writing signed by such
party.  No waiver by a party of any breach of this Agreement or of any warranty
or representation hereunder by the other party shall be deemed to be a waiver of
any other breach, warranty or representation by such other party (whether
preceding or succeeding and whether or not of the same or similar nature), and
no acceptance of payment or performance by a party after any breach by the other
party shall be deemed to be a waiver of any breach of this Agreement or of any
representation or warranty hereunder by such other party, whether or not the
first party knows of such breach at the time it accepts such payment or
performance.  No failure or delay by a party to exercise any right it may have
by reason of the default of the other party shall operate as a waiver of such
default or as a modification of this Agreement nor shall any such failure or
delay prevent the exercise of any right by the nonbreaching party while the
default continues.  Without limiting the generality of the foregoing, in the
event that for any reason any item required to be delivered to any person
hereunder shall not be delivered when required, then the party obligated to make
such delivery shall nevertheless remain obligated to deliver the same to the
party entitled to receive such delivery provided the other party delivers a
written request for such delivery within six (6) months following the Condition
Satisfaction Date and nothing (including the closing of the transaction
hereunder) shall be deemed a waiver by the party entitled to receive such
delivery of any such requirement, except an express written waiver or a failure
to make such request within the foregoing time period.

        3.11  Outside Date.  In the event that for any reason the conditions
              ------------                                                  
precedent to the effectiveness of the transactions contemplated hereby shall not
have occurred on or before the Condition Satisfaction Date, either party hereto
may extend the Condition Satisfaction Date to October 15, 1997, by delivering
written notice of such election to the other party.  In the event that for any
reason such conditions precedent have not been satisfied on or before October
31, 1997, then (unless NHP or Laureate, as applicable, commences an action to
specifically enforce this Agreement within 30 days thereafter) either party may
at any time after the Condition Satisfaction Date, by written notice to the
other party, terminate this Agreement and the obligations of the parties
hereunder; provided, however, that such termination shall not release any party
           --------  -------

termination.

        3.12  Cost Advance.  NHP hereby acknowledges receipt of the Cost
              ------------                                              
Advance.  Concurrently with the Effective Time, the Cost Advance shall be
credited to Laureate's costs under Section 4.1(a)(vi) below.  In the event this
Agreement is terminated, the Cost Advance shall be treated as provided for in
Section 3.6 herein.

  described in Section 3.5(b) occur affecting only one (1) Property, then

  Agreement; provided however, that Laureate shall cause the general and limited

  partnership interests of the Real Estate Partnership owning such Property to
  be transferred to another entity, and as of the Condition Satisfaction Date,
  Investments and Laureate Properties shall not own any partnership interests in
  such Real Estate Partnership.  In addition, should the events described in
  this Section occur, then the Merger Price shall be reduced by the amount
  allocated to the applicable Property as shown on Exhibit X, and the applicable
                                                   ---------                    
  New Lease shall be revised to reflect the removal of such Property.

            (b) Should the events described in Section 3.5(b) not occur with
  respect to any Property and should Investments fail to acquire the minority
  partnership interest in The Arboretum I Limited Partnership as provided for in
  Section 2.2(a)(iii), then the acquisition of such minority partnership
  interest shall not serve as a condition precedent to NHP's obligations under
  this Agreement and at the election of Laureate either of (i) or (ii) as
  follows shall apply:

                (i) If this Section 3.12(b)(i) applies, the Arboretum shall be
        deleted from the transactions described in this Agreement, in which
        event Laureate shall cause the transfer of any general and limited
        partnership interests of The Arboretum II Limited Partnership owned by
        Investments and/or Laureate Properties to be transferred to another
        entity, and as of the Condition Satisfaction Date Investments and
        Laureate Properties shall not own any partnership interests in The
        Arboretum II Limited Partnership.  In addition, should this Section
        3.12(b)(i) apply, then the Merger Price shall be reduced by the amount
        allocated to The Arboretum I Limited Partnership as shown on Exhibit X,
                                                                     --------- 
        and the applicable New Lease shall be revised to reflect the removal of
        such Property; or

                (ii) If this Section 3.12(b)(ii) applies, only the general
        partnership interest in The Arboretum I Limited Partnership shall be
        included in the transactions described in this Agreement, in which event
        (A) the Merger Price shall be reduced by 35% of (x) the amount allocated
        to The Arboretum I Limited Partnership as shown on Exhibit X, minus (y)
                                                           ---------

        negotiations to make such reasonable amendments to the partnership
        documents for The Arboretum I Limited Partnership, to obtain such
        consents from the limited partnership therein and to resolve any legal
        issues arising out of any referral relationship between the parties in
        The Arboretum II Limited Partnership and the Healthcare Facility at The
        Arboretum, all as may be required to effectuate this alternative without
        additional liability or obligations being borne by NHP.

                (iii)  If this Section 3.12(b) applies and Laureate has not
        elected between subparagraphs (i) and (ii) above by the Condition
        Satisfaction Date, then Laureate shall be deemed to have selected
        subparagraph (i).

Existing Encumbrances.  If, despite good faith efforts to do so, Laureate has
not received such approvals by the Condition Satisfaction Date, the parties
shall enter into good faith negotiations to agree upon such revisions to this
Agreement and the New Leases as are reasonably necessary or appropriate in order
to place the Landlord in as close a position as reasonably practicable with
respect to the Tenant Personal Property under the New Leases.

of Investments arising under that certain Guaranty of Lease dated April 25, 1997
in favor of John W. Lynch and Daisy Lynch in connection with the Layton Terrace
development in the City of Greenfield, Wisconsin.  However, if such release is
not forthcoming by said date, as a condition subsequent to the Merger Laureate
shall continue to use its commercially reasonable efforts to obtain such release
and shall indemnify and hold NHP, the NHP Subsidiaries and the Real Estate
Partnerships harmless from any liability under the guaranty described in this
Section 3.15.  The failure of Laureate to obtain such release on or before a
date six (6) months from the Effective Time, or the failure of Laureate to honor
the indemnity set forth in this Section 3.15 shall be deemed a default by
Investments and Laureate Properties under this Agreement.

  customary year-end adjustments and except that (i) no item shall fail to be
  included therein or excluded therefrom on the basis of materiality,

  Balance Sheet shall be delivered by NHP to Investments and Laureate
  Properties.  Investments, Laureate Properties and their representatives shall
  be provided complete access to all work papers and other information used by
  NHP in preparing the Adjusted Closing Balance Sheet.  The Adjusted Closing
  Balance Sheet, when delivered by NHP to Investments and Laureate Properties,
  shall be deemed conclusive and binding on the parties, but only for purposes
  of determining (i) the amount of the Continuing Debt and Existing Encumbrances
  utilized in determining the preliminary Equity Value, and (ii) the Closing
  Cash Adjustment.

            (d) Closing Cash Adjustment.  A closing cash adjustment (the
                -----------------------                                 
  "Closing Cash Adjustment") shall be determined from the Adjusted Closing
  Balance Sheet and shall consist of (i) the amount of cash of Investments and
  Laureate Properties and the Real Estate Partnerships as shown thereon, less
  (ii) any overdrafts, the amount of accrued interest on the Continuing Debt and
  Existing Encumbrances and the projected liability of Investments and Laureate
  Properties for federal and state built-in gain Taxes as described in Section
  5.1(v) hereof (net of any estimated deposits of such Taxes).  If the Closing
  Cash Adjustment is a positive number, NHP shall pay such amount to the
  Shareholders at the Effective Time.  If the Closing Cash Adjustment is a
  negative number, the Shareholders shall pay such amount to NHP at the
  Effective Time.

            (e) Final Closing Balance Sheet.  Within thirty (30) business days
                ---------------------------                                   
  following the Effective Time, NHP shall deliver to the Shareholders a
  reconciliation between the Adjusted Closing Balance Sheet and a combined
  balance sheet and related notes prepared by NHP as of the Effective Time (the
  "Final Closing Balance Sheet").  Within fifteen (15) business days of such
  delivery, NHP and the Shareholders shall mutually agree on the Final Closing
  Balance Sheet, the reconciliation thereof to the Adjusted Closing Balance
  Sheet and (i) any increase or decrease necessary to adjust the Equity Value
  determined pursuant to Section 4.2(c) in order to properly reflect the
  balances of the Continuing Debt and Existing Encumbrances set forth in the
  Final Closing Balance Sheet and (ii) any increase or decrease necessary to the
  Closing Cash Adjustment in order to reflect the final Closing Cash Adjustment
  based on the Final Closing Balance Sheet.  Any such combined net increase or
  decrease shall be immediately paid in cash by the Shareholders to NHP or by
  NHP to the Shareholders, as applicable.  Any failure of the Shareholders to
  make any payment required by the foregoing timetable shall be deemed a default
  by Investments and Laureate Properties under this Agreement.

  condition of Laureate), which Permits are in full force and effect and

  conditions or any Permit in such manner (i) as would permit any other party to

  Investments and Laureate Properties represent that the schedule to be
  delivered to NHP pursuant to Section 3.2(i) above will be a correct estimate
  of such built-in gain and Taxes thereon based on the facts and circumstances

  delivered pursuant to Section 3.2(i).  Notwithstanding that the payment of
  Taxes on built-in gain pursuant to this Section 5.1(av) is made on an
  estimated basis, it is the intention of the parties to this Agreement that all
  actual Taxes on built-in gain arising from the transactions described in this
  Section 5.1(av) will not be borne by NHP or its Affiliates.  Therefore, if
  such actual Taxes exceed the estimated Taxes paid under this Section 5.1(av),
  such excess will be charged against and borne by the then Guarantors under the
  Affirmation and Amendment of Transaction Guaranty.  Moreover, it is the
  intention of the parties to this Agreement that NHP and its Affiliates shall
  not bear any Taxes on built-in gain from Investments or Laureate Properties
  unless such Taxes arise from the sale, distribution, exchange or other
  distribution of the Property or any portion thereof in a taxable transaction
  subsequent to the Effective Time or from a breach of NHP's obligations set
  forth in Section 5.5(c) below.  Therefore, if any such Taxes arise after the
  Effective Time, except by reason of any such disposition or breach, the same
  shall be charged to and borne by the then Guarantors under the Affirmation and
  Amendment of Transaction Guaranty.

  true and correct copies of its Annual Report on Form 10-K for the year ended
  December 31, 1996 and its Quarterly report on Form 10-Q for the quarters ended
  March 31, 1997 and June 30, 1997 as filed with the Commission under the
  Exchange Act (all of the foregoing being collectively referred to as the "SEC
  Documents").  As of their respective filing dates, the SEC Documents complied
  in all material respects with the requirements of the Securities Act and the
  Exchange Act, and the applicable rules and regulations of the Commission
  thereunder, as the case may be, and the SEC Documents contained no untrue
  statement of a material fact or omitted to state a material fact required to
  be stated therein or necessary to make the statements made therein, in light
  of the circumstances in which they were made, not misleading, except to the
  extent corrected by a document subsequently filed with the Commission prior to
  the date hereof.  The financial statements of NHP, including the notes
  thereto, included in the NHP SEC Documents (the "NHP Financial Statements")
  comply as to form with applicable accounting

  requirements and with the published rules and regulations of the Commission
  with respect thereto, have been prepared in accordance with generally accepted
  accounting principles consistently applied (except as may be indicated in the
  notes thereto or, in the case of unaudited statements, as permitted by Form
  10-Q of the Commission) and present fairly the consolidated financial position
  of NHP at the dates thereof and of its operations and cash flows for the
  period then ended (subject, in the case of unaudited statements, to normal,
  recurring audit adjustments).  There has been no change in NHP accounting
  policies except as described in the notes to the NHP Financial Statements.

            (i) No Material Adverse Change.  Since the date of the June 1997,
                --------------------------                                   
  balance sheet included in NHP Financial Statements, NHP has conducted its
  business in the ordinary course consistent with past practices and there has
  not occurred:  (a) any material adverse change in the consolidated financial
  conditions, liabilities, assets, results of operations or business of NHP and
  its subsidiaries taken as a whole; (b) any damage to, destruction or loss of
  any assets of NHP or any subsidiary of NHP (whether or not covered by
  insurance) that would have a Materially Adverse Effect on the consolidated
  financial condition or business of NHP and its subsidiaries, taken as a whole;
  or (c) any sale of a material amount of property of NHP, except in the
  ordinary course of business.

            (j) Status of NHP Stock.  On and after the Effective Time, upon due
                -------------------                                            
  and proper exchange of Investments and Laureate Properties Common Stock
  therefor, the shares of NHP Stock to be issued to the Shareholders will be
  validly authorized, duly issued, fully paid and nonassessable.

        5.4 Indemnifications.
            ---------------- 

            (a) Indemnification by Laureate.  Laureate shall hold harmless,
                ---------------------------                                
  indemnify and defend NHP, the NHP Subsidiaries, the Real Estate Partnerships
  and the Property from and against any Claim to the extent that the same (i)
  results from the inaccuracy or breach of (or results from or arises out of any
  actual or alleged fact that is inconsistent with) any representation, warranty
  or covenant of Laureate contained in this Agreement or in any document
  executed in connection with this Agreement, (ii) results from any breach or
  default by Laureate under this Agreement, (iii) arises out of the operations
  of Investments or Laureate Properties prior to the Effective Time, including
  any and all agreements, whether written or oral, to which Investments or
  Laureate Properties is or was a party prior to the Effective Time, and whether
  or not the facts or circumstances out of which the same arise have previously
  been disclosed to NHP, (iv) arises out of the negligent or intentional act or
  omission of Laureate or (v) arises out of the use of the Property on or prior
  to the Effective Time or the operations, acts or omissions of the Real Estate
  Partnerships and/or the Existing Operating Partnerships on or prior to the
  Effective Time.  Nothing in this Agreement shall be construed to relieve
  Laureate of any liability which Laureate may have to NHP under any Laws
  relating to Hazardous Materials; provided, however,
                                   --------  ------- 

                                       50
<PAGE>
 
  Laureate shall have no liability in connection with any such Hazardous
  Materials, the presence of which is disclosed to NHP in writing pursuant to
  any environmental audits or other environmental assessments, the results of
  which are delivered to NHP prior to the Condition Satisfaction Date.

            (b) Indemnification by NHP.  NHP shall hold harmless, indemnify and
                ----------------------                                         
  defend Laureate and the Shareholders from and against any Claim to the extent
  that the same (i) results from the inaccuracy or breach of (or results from
  any actual or alleged fact that is inconsistent with) any representation,
  warranty or covenant of NHP contained in this Agreement or in any document
  executed in connection with this Agreement, (ii) results from any breach or
  default by NHP under this Agreement, (iii) arises out of the negligent or
  intentional act or omission of NHP, to the extent such Claim arises out of
  such negligent or intentional act or omission of NHP occurring after the
  Effective Time or occurring during the course of NHP's inspection of the
  Property prior to the Effective Time, or (iv) arises solely out of any act,
  event or omission of NHP occurring or arising after the Effective Time and
  imposing any liability under any Laws relating to Hazardous Materials.

            (c) Indemnity by Laureate Regarding Built-in Gain.  Without limiting
                ---------------------------------------------                   
  Laureate's liability pursuant to Section 5.4(a) above, Laureate shall hold
  harmless, indemnify and defend NHP, the NHP Subsidiaries, the Real Estate
  Partnerships and the Property from and against any Claim for Taxes and any
  interest or penalties thereon which arises from, or relates to, the
  transactions described in Section 5.1(av).  Notwithstanding anything contained
  herein NHP recognizes that the sale of the Property after the Effective Time
  may result in tax on built-in gain other than as reflected in Section 5.1(av).
  NHP further acknowledges that the indemnity by Laureate in this Section 5.4(c)
  does not extend to any tax on built-in gain other than gain resulting from the
  transactions described in Section 5.1(av).

            (d) General Indemnity Provisions.  Each indemnity provided for under
                ----------------------------                                    
  this Agreement shall be subject to the following provisions:

                (i) The indemnity shall cover the costs and expenses of the
        indemnitee, including reasonable attorneys' fees and costs (including
        expert fees), related to any actions, suits or judgments incident to any
        of the matters covered by such indemnity.

                (ii) The indemnitee shall notify the indemnitor in writing of
        any Claim against the indemnitee covered by the indemnity within forty-
        five (45) days after it has notice of such Claim, but failure to notify
        the indemnitor shall in no case prejudice the rights of the indemnitee
        under this Agreement unless the indemnitor shall be prejudiced by such
        failure and then only to the extent the indemnitor shall be prejudiced
        by such failure.  Should the indemnitor fail to discharge or undertake
        to defend the indemnitee against such liability upon learning of the
        same, then the indemnitee (upon further notice) may settle such

                                       51
<PAGE>
 
        liability, and the liability of the indemnitor hereunder shall be
        conclusively established by such settlement, the amount of such
        liability to include both the settlement consideration and the
        reasonable costs and expenses, including attorneys' fees and costs
        (including expert fees), incurred by the indemnitee in effecting such
        settlement.

                (iii)  The indemnity shall also run in favor of any officer,
        director, employee, advisor, accountant, attorney, partner or
        shareholder of the indemnitee or any person or entity having a direct or
        indirect ownership interest in the indemnitee.

                (iv) The indemnities set forth in this Section 5.4 are expressly
        intended to survive the Merger.

                (v) Appropriate adjustments shall be made so as to reduce the
        amount of any Claim under this Section 5.4 to take into account
        insurance coverage and amounts received from third parties.

            (e) Limitations on Indemnification.
                ------------------------------ 

                (i) Time Limitation.  No claim or action shall be brought under
                    ---------------                                            
        Section 5.4(a) for any Claim after December 31, 2012, provided, however,
        that there shall be no time limitation on claims or actions brought for
        breach of any representation or warranty made by Laureate in or pursuant
        to Sections 5.1(o), 5.1(v), 5.1(au), 5.1(av), 5.1(aw) or 5.4(c) hereof.

                (ii) Amount Limitation.  There shall be an aggregate ceiling of
                     -----------------                                         
        $20,000,000 on the obligations of Laureate under this Section 5.4,
        provided, however, that claims for indemnification for breach of any
        representation or warranty made by Laureate in or pursuant to Sections
        5.1(o), 5.1(v), 5.1 (au), 5.1(av), 5.1(aw) or 5.4(c) shall not be
        subject to the limitations of this Section 5.4(e)(ii) and shall not be
        taken into account in determining the total amount of the obligations of
        Laureate under this Section 5.4 subject to such ceiling.

        5.5 Certain Tax Matters.
            ------------------- 

            (a) Reorganization.  The parties acknowledge that the Merger is
                --------------                                             
  intended to qualify as a reorganization under Section 368(a)(1)(A) of the
  Code, and each party agrees to report the Merger as such a reorganization for
  income tax purposes.  However, and without limiting the generality of Section
  5.1(av) and 5.2 above, NHP shall have no liability to Laureate or the
  Shareholders, if, despite NHP having reported the Merger as required by this
  Section 5.5(a), and despite NHP's compliance with Section 5.5(c), the Merger
  fails to so qualify.

                                       52
<PAGE>
 
            (b) Election.  NHP, for itself and on behalf of, the NHP
                --------                                            
  Subsidiaries, agrees to elect, pursuant to Internal Revenue Service Notice 88-
  19 and any applicable regulations, to be subject to rules similar to the rules
  of Section 1374 of the Code with respect to all property acquired from
  Laureate in the Merger.  The Shareholders shall not be liable in any way for
  any Taxes incurred by Investments, Laureate Properties, the Real Estate
  Partnerships, NHP or the NHP Subsidiaries as a result of the failure to make
  such election.

            (c) Actions Following Closing.  NHP, for itself and on behalf of the
                -------------------------                                       
  NHP Subsidiaries, represents, warrants and covenants that it has no plan or
  intention to, and agrees that for a least three years after the Effective
  Time, it shall use its reasonable best efforts not to take any action that
  would cause the Merger to fail to qualify as a reorganization under Section
  368(a)(1)(A) of the Code, including (without limitation) causing or
  permitting:  (i) NHP to own less than 100% of the issued and outstanding
  shares of capital stock of either QRS 1 or QRS 2, (ii) either QRS 1 or QRS 2
  to liquidate or to merge into another corporation, and (iii) QRS 1 or QRS 2 to
  voluntarily sell or otherwise dispose of a substantial portion of the Property
  or to cease using at least a significant portion of the Property in its
  business.  NHP will (at no cost to NHP) cooperate with Laureate's preparation,
  execution and filing of the short taxable year tax returns referenced in
  Section 5.1(o)(v) above.

        5.6 Hart-Scott-Rodino Act.  No party has entered into this Agreement in
            ---------------------                                              
reliance on any representation by any other party (except as to factual matters)
with respect to the application of the Hart-Scott-Rodino Antitrust Improvements
Act to the transactions described in this Agreement, and no party has made any
such representation to any other party.  Each party to this Agreement shall rely
entirely on its own investigation and that of its advisors with respect to such
matters.  Without limiting the generality of the foregoing, neither party hereto
shall have any liability whatsoever to any other party with respect to such
matters.

        6.3  Limitation of Liability.
             ----------------------- 

          (a)  No advisor, trustee, director, officer, employee, accountant,
attorney, beneficiary, shareholder, partner, participant or agent of or in NHP
shall have any personal liability, directly or indirectly, under or in
connection with this Agreement or any agreement made or entered into under or
pursuant to the provisions of this Agreement, or any amendment or amendments to
any of the foregoing made at any time or times, heretofore or hereafter.
Laureate and its respective successors and assigns and, without limitation, all

          (b)  No advisor, trustee, director, officer, employee, accountant,

        6.4 Entire Agreement; Amendments; Captions.  This Agreement and the

        6.6  Time of the Essence; Non-Business Days.  Subject to the next full
             --------------------------------------                           
sentence, time is of the essence of this Agreement.  Whenever action must be
taken (including the giving of notice or the delivery of documents) under this
Agreement during a certain period of time or by a particular date that ends or
occurs on a non-business day, then such period or date shall be extended until
the immediately following business day.  As used herein, "business day" means
                                                          ------------       
any day other than Saturday, Sunday or a federal holiday.

        6.7 Terminology.  Whenever the words "including", "include" or
            -----------                                               
"includes" are used in this Agreement, they should be interpreted in a non-
exclusive manner as though the words, "without limitation," immediately followed
the same.  Except as otherwise indicated, all Section, Exhibit and Schedule
references in this Agreement shall be deemed to refer to the Sections, Exhibits
and Schedules in or to this Agreement.

        6.8 Attorneys' Fees.  In the event any legal action or proceeding is
            ---------------                                                 
commenced to interpret or enforce the terms of, or obligations arising out of,
this Agreement, or to recover damages for the breach thereof, the party
prevailing in any such action or proceeding shall be entitled to recover from
the non-prevailing party all reasonable attorneys' fees and reasonable costs and
expenses incurred by the prevailing party, including such fees and costs
incurred with respect to appeals, arbitrations and bankruptcy proceedings.  As
used herein, "attorneys' fees" shall mean the reasonable fees and expenses of
counsel to the parties hereto, which may include printing, photostating,
duplicating and other expenses, air freight charges, and fees billed for law
clerks, paralegal, librarians and others not admitted to the bar but performing
services under the supervision of an attorney.

        6.9 Cumulative Remedies.  No remedy conferred upon a party in this
            -------------------                                           
Agreement is intended to be exclusive of any other remedy herein or by law
provided or permitted, but each shall be cumulative and shall be in addition to
every other remedy given hereunder or now or hereafter existing at law, in
equity or by statute (except as otherwise expressly herein provided).

        6.10  Governing Law.  This Agreement shall be construed and enforced in
              -------------                                                    
accordance with the internal laws of the State of Wisconsin without regard to
the rules governing choice of law.

        6.11  Successors and Assigns.  Neither NHP nor Laureate may assign or
              ----------------------                                         
transfer its rights or obligations under this Agreement without the prior
written consent of the other party (in which event such transferee shall assume
in writing all of the transferor's obligations hereunder, but such transferor
shall not be released from its obligations hereunder).  No consent given by
either party hereto to any transfer or assignment of the other party's rights or
obligations hereunder shall be construed as a consent to any other transfer or
assignment of such other party's rights or obligations hereunder.  No transfer
or assignment in violation of the provisions hereof shall be valid or
enforceable.  Subject to the foregoing, this Agreement and the terms and
provisions hereof shall inure to the benefit of and be binding upon the
successors and assigns of the parties.

              ---------------------------

covenants of NHP and the NHP Subsidiaries in Section 5.5 hereof.  No other

              -----------------------                                           
executed, and continuing thereafter until NHP has approved all contingencies

attorneys' fees) in connection with such tests and inspections.  Any disapproval
by Laureate of a Phase II environmental assessment for the Healthcare Facility

consent of the other parties.  This provision shall not apply, however, to any

prior to such disclosure.  In no event shall any public announcement or written
