                                   Re:      Form S-3 Registration

Gentlemen:

     We  have  acted  as  special  tax  counsel  to   Healthcare   Realty  Trust
Incorporated,  a Maryland  corporation (the  "Company"),  in connection with the
Registration  Statement  on Form  S-3  (File  No.  33-97888)  and the  documents
incorporated by reference therein (the  "Incorporated  Documents") and Amendment
No.  1  thereto  filed  with  the  Securities  and  Exchange   Commission   (the
"Commission")  pursuant to the  provisions  of the  Securities  Act of 1933,  as
amended  (the "Act")  relating to the  registration  of shares of Common  Stock,
warrants to purchase Common Stock,  shares of preferred stock of the Company and
debt  securities of the Company (the "Shelf  Securities") to be issued from time
to time by the  Company.  The  Company's  registration  statement,  as  amended,
including  the  Incorporated  Documents,  is  hereinafter  referred  to  as  the
"Registration  Statement"  and the  related  prospectus  dated  November 2, 1995
(including  the  Incorporated  Documents),  relating to the Shelf  Securities is
hereinafter  referred to as the "Basic  Prospectus".  The Basic  Prospectus,  as
supplemented by the prospectus  supplement dated February 24, 1998,  relating to
the offering of up to 356,347  shares of common stock,  par value $.01 per share
of the Company  (the  "Shares") by the  Underwriters,  in the form first used to
confirm sales of the Shares, is hereinafter referred to as the "Prospectus".  In
connection with the Registration Statement,  you have requested our opinions (A)
that the Company was and is organized in conformity  with the  requirements  for
qualification  as a real estate  investment  trust  ("REIT")  under Sections 856
through 860 of the Internal  Revenue  Code of 1986,  as amended (the "Code") and
that its method of operation as described in the  Prospectus  permits it to meet
the  requirements for  qualification  and taxation as a REIT, and (B) confirming
the  statements   made  under  the  caption   "Federal   Income  Tax  and  ERISA
Considerations" in the Basic Prospectus and "Federal Income Tax  Considerations"
in the Prospectus  Supplement.  All capitalized  terms in this opinion which are
defined in the  Registration  Statement and the  Prospectus  shall have the same
respective  meanings  as  set  forth  in  the  Registration  Statement  and  the
Prospectus.

     In rendering  our opinion,  we have  examined and relied upon the following
documents and other materials:

     1.  Schedules  prepared and  delivered by officials of the Company  setting
forth:

     (a) REIT  taxable and gross  income for the fiscal year ended  December 31,
1997,  together with a schedule of actual  dividends  distributed  and projected
dividends to be distributed  in accordance  with Code Section 858 and compliance
with the distribution requirements of Code Section 857(a); and

     (b) Compliance with the applicable REIT ratios or tests for the fiscal year
ended December 31, 1997, including:

         Income tests:

         (1)      95% gross income test for the year;
         (2)      75% gross income test for the year;
         (3)      30% gross income test for the year;

         Asset tests:

         (1)      75% asset test at the end of each quarter;
         (2)      25% asset test at the end of each quarter;
         (3)      10% asset test at the end of each quarter;
         (4)      5% asset test at the end of each quarter.

     2. The Company's certificate, dated as of February 25, 1998.

     In  addition,   we  have  examined  such  additional  records,   documents,
certificates and other instruments and made such  investigations of fact and law
as in our  judgment  are  necessary  or  appropriate  to enable us to render the
opinion expressed below.

     In rendering our opinion, we have made the following assumptions:

     1. Five or fewer shareholders have not owned,  directly or indirectly under
the rules of Code Section 544, as modified by Code Section  856(h),  at any time
since the  completion of the initial public  offering,  over 50% in value of the
outstanding stock of the Company;  and "Excess Shares" (defined in the Company's
Second  Articles of Amendment and  Restatement to be shares of a value exceeding
9.9% in value of the  outstanding  shares of the Company) held or deemed held by
any person  (pursuant to applicable  rules of attribution) are deemed to have no
value or voting rights.

     2. The Company has and will comply with any and all procedural requirements
for REIT status set forth in Code  Sections 856 through 860 and the  regulations
thereunder,  including the timely making of such elections and the obtaining and
disclosing of such  information  as is required on the federal tax returns to be
filed by the Company.

     3. The Company will operate in accordance with its past and proposed method
of  operation  as  described  in its filings  with the  Securities  and Exchange
Commission  under the Securities Act of 1933 and the Securities  Exchange Act of
1934, as amended.

     4. All  partnerships  in which the Company may have an  ownership  interest
will own only "real estate  assets" and cash  reserves.  All activities of those
partnerships  will consist of  activities  permitted to be undertaken by a REIT,
and income of such  partnerships,  other than interest  income on cash reserves,
shall be "rents from real property".

     5. Each corporation in which the Company has acquired or acquires an equity
interest shall either be a "Qualified REIT Subsidiary" under Code Section 856(i)
or a  corporation  in which the  Company  will not own over ten  percent  of the
outstanding voting securities,  and the securities owned of any such corporation
which is not a Qualified REIT  Subsidiary will not be greater in value than five
percent (5%) of the value of the total assets of the Company.

     On the basis of and in  reliance  on the  foregoing,  we wish to advise you
that under current law, including  relevant  statutes,  regulations and judicial
and  administrative  precedent  (which law is subject to change on a retroactive
basis),  in our opinion the Company was and is organized in conformity  with the
requirements  for  qualification as a REIT under the Code and that its method of
operation as described in the Prospectus permits it to meet the requirements for
qualification and taxation as a REIT.

     In addition,  we also hereby confirm the statements  made under the caption
"Federal Income Tax and ERISA Considerations" in the Basic Prospectus, including
Item 5 of the Company's Quarterly Report on Form 10-Q for the quarter ended June
30, 1996,  incorporated by reference therein, under the heading "Certain Federal
Income  Tax and ERISA  Considerations"  and as  supplemented  under the  heading
"Federal Income Tax Considerations" contained in the Prospectus Supplement.

     Since actual  qualification  as a REIT is  dependent  upon future facts and
circumstances,  it is possible that future events, operations,  distributions or
other  actions will cause the Company not to qualify or continue to qualify as a
REIT.
