This Amendment No. 1 to Schedule 13D (this "Amendment") filed pursuant
to Section 13d- 2(a) of the General Rules and Regulations under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), should be read in
conjunction with the Schedule 13D (the "Schedule 13D") filed with the Securities
and Exchange Commission on June 9, 1997 via EDGAR. This Amendment amends the
Schedule 13D only with respect to the items set forth below. All capitalized
terms not otherwise defined herein shall have the meanings ascribed thereto in
the Schedule 13D.
Item 5. Interest in Securities of the Issuer.
(a) As of the date hereof, Partners II owns an aggregate of 228,976
shares of the Issuer's Common Stock and AEW HSP owns an aggregate of 73,263
shares of the Issuer's Common Stock, representing, respectively, approximately
2% and 0.6% (or an aggregate of approximately 2.6%) of the 11,404,631 shares of
the Issuer's Common Stock believed to be outstanding.
To the best knowledge of the Reporting Persons, as of the date hereof,
none of the Reporting Persons, nor any officer or director of AEW II Corp or AEW
CMI beneficially own any other shares of Common Stock of the Issuer.
Partners II has an agreement with its limited partners whereby, subject
to certain limitations, such limited partners are offered the opportunity to
invest, through a co-investment vehicle, in any entity in which an investment is
made by Partners II. In the case of the securities of the Issuer, such
co-investment by the limited partners of Partners II was made through AEW HSP.
Partners II may be deemed to be in a group with AEW HSP, but disclaims
beneficial ownership of the securities owned by AEW HSP (other than any
securities beneficially owned by Partners II in its capacity as a general
partner of AEW HSP) for purposes of Section 13 of the Exchange Act, Section 16
of the Exchange Act or for any other purpose.
Pursuant to a Stockholders Agreement dated as of September 9, 1996 (the
"Stockholders Agreement") by and among the Issuer, Health Science Properties
Holding Corporation, a Maryland corporation ("HSP Holding") and Partners II, HSP
Holding previously agreed to vote its shares of the Issuer's Common Stock to
elect directors of the Issuer nominated by Partners II. The Stockholders
Agreement is described more fully in Item 6. Because Partners II currently owns
less than 7% of the voting securities of the Issuer, the voting provisions of
the Stockholders Agreement have terminated. Partners II may still be deemed to
be in a group with HSP Holding, but disclaims beneficial ownership of the
securities owned by HSP Holding for purposes of Section 13 of the Exchange Act,
Section 16 of the Exchange Act or for any other purpose.
(b) (i) AEW HSP has the sole power to direct the voting and
disposition of the 73,263 shares of Common Stock held by it.
(ii) As general partners of AEW HSP, Partners II and Partners
II Holding are deemed to have shared power to direct the voting and disposition
of the 73,263 shares of Common Stock held by AEW HSP. In addition, Partners II
has the sole power to direct the voting and disposition of the 228,976 shares of
Common Stock held by it.
(iii) As general partner of Partners II, AEW II LP is deemed
to have the sole power to direct the voting and disposition of the 228,976
shares of Common Stock held by Partners II and shared power to direct the voting
and disposition of the 73,263 shares of Common Stock held by AEW HSP.

(iv) As general partner of AEW II LP, Partners II Holding is
deemed to have the sole power to direct the voting and disposition of the
228,976 shares of Common Stock held by Partners II and the sole power to direct
the voting and disposition of the 73,263 shares of Common Stock held by AEW HSP.
(v) As general partner of Partners II Holding, AEW II Corp is
deemed to have the sole power to direct the voting and disposition of the
228,976 shares of Common Stock held by Partners II and the sole power to direct
the voting and disposition of the 73,263 shares of Common Stock held by AEW HSP.
(vi) As controlling stockholder of AEW II Corp, AEW CMLP is
deemed to have the sole power to direct the voting and disposition of the
228,976 shares of Common Stock held by Partners II and the sole power to direct
the voting and disposition of the 73,263 shares of Common Stock held by AEW HSP.
(vii) As general partner of AEW CMLP, AEW CMI is deemed to
have the sole power to direct the voting and disposition of the 228,976 shares
of Common Stock held by Partners II and the sole power to direct the voting and
disposition of the 73,263 shares of Common Stock held by AEW HSP.
(c) Other than as set forth below, to the best knowledge of the
Reporting Persons, none of the Reporting Persons nor any officer or director of
AEW II Corp or AEW CMI has effected any transactions in the Common Stock during
the past 60 days.
On July 22, 1998, the Reporting Persons sold, through an
underwritten registered offering, an aggregate of 1,357,000 shares of the
Issuer's Common Stock. Of the Shares sold, 1,028,063 were held directly by
Partners II and 328,937 were held directly by AEW HSP. All shares were sold at a
price of $29.00 per share.
(d) Not applicable.
(e) July 22, 1998.

Item 6. Contracts, Arrangements, Understanding or Relationships With Respect to
Securities of the Issuer.
Pursuant to the Stockholders Agreement, Partners II previously had the
right to include at least one nominee on the ballot for the election of
directors of the Issuer, and one nominee on the ballot for the election of
directors of ARE-QRS Corp., a Maryland corporation, a wholly owned subsidiary of
the Issuer ("Subsidiary") and HSP Holding had agreed to vote its shares of the
Issuer's Common Stock for such nominees included on the ballot for the election
of directors of the Issuer and the Issuer had agreed to take all actions
necessary to cause the election of the nominee at Subsidiary. Because Partners
II currently owns less than 7% of the voting securities of the Issuer, Partners
II no longer has any right to nominate any directors of the Issuer or
Subsidiary.
