ITEM 2.  ACQUISITION OF ASSETS

     On April 25, 2001, Boston Properties Limited Partnership, the operating
partnership subsidiary (together with its direct and indirect wholly-owned
subsidiaries, "BPLP") of Boston Properties, Inc. (the "Company"), completed the
acquisition of the 59-story, 1.6 million square foot Citigroup Center in New
York City at a purchase price of approximately $725 million.  BPLP completed the
acquisition through a joint venture with affiliates of Allied Partners, a
private family-owned real estate investment company founded in 1993 (together
with its affiliates, "Allied").  The sellers were Dai-Ichi Life Investment
Properties, Inc and Citibank, N.A. pursuant to contracts that were assigned to
the joint venture as part of a series of transactions leading to the closing of
the acquisition. Allied invested $35 million in common equity in the joint
venture. BPLP invested the balance of approximately $195 million of equity
required to complete the transaction, with approximately $66.5 million in common
equity and the balance in preferred equity.

     Citigroup Center, the 59-story, 1.6 million square foot skyline building
known for its distinctive cantilevered structure and angled top, was built in
1977 and was designed by Hugh Stubbins & Associates and Emery Roth & Sons.  The
atrium, open-air plaza and office tower lobby were renovated in 1997.  The
property is 100% leased and the tenants include Citigroup, O'Melveny & Myers,
Kirkland & Ellis and AT Kearney, among other well-known tenants.  Citigroup
Center provides direct access to New York City's transit system through its
prime location atop a major subway station.

     The transaction was consummated through a newly-formed Delaware limited
liability company, of which BPLP is the managing member.  The total acquisition
cost of approximately $755 million, including purchase price, closing costs and
mortgage-recording taxes, was funded through a $525 million first mortgage
provided by an affiliate of Deutsche Bank and equity investments in the limited
liability company by BPLP and Allied.  Giving effect to the closing and all
related transactions, BPLP holds a $66.5 million Class A common equity interest
and a $128.5 million preferred equity interest in the limited liability company.
Allied as non-managing member holds a $35.0 million Class B common equity
interest.  In addition, BPLP and Allied hold residual membership interests equal
to 65.5% and 34.5%, respectively, in the joint venture.  BPLP funded its $195
million investment in common and preferred equity interests in the joint venture
through borrowings under its existing unsecured revolving line of credit and
available cash.

     The preferred equity and Class A common equity interests held by BPLP will
earn a cumulative compounding 10% priority return (the "BPLP Priority Return")
which, for a period up to 10 years after the closing, will be paid out of cash
flow or will accrue and be paid out of the proceeds of any capital transaction.
The Class B common equity interest held by Allied will earn no return for the
first 10 years. If any portion of the preferred equity interest remains
outstanding after the tenth anniversary of the closing, thereafter Allied's
Class B common equity interest will earn a cumulative compounding 10% return
(the "Allied Priority Return"), which will be payable out of cash flow or the
proceeds of any capital transaction before the BPLP Priority Return for the same
period and any accumulated unpaid portion of the BPLP Priority Return for the
first 10 years can be paid. During the first 10 years, BPLP's preferred equity
investment and any accumulated unpaid portion of the BPLP Priority Return will
be payable first out of the proceeds

                                       2


of any refinancing of the property and any additional refinancing proceeds will
be used to repay the Class A and Class B common equity investments
proportionately. After the tenth anniversary of the closing, refinancing
proceeds will be used first to pay the Allied Priority Return, then to pay the
BPLP Priority Return (including any accumulated unpaid amount accrued during the
first 10 years), then to repay BPLP's preferred investment, and finally to repay
the Class A and Class B common equity investments proportionately. Thereafter,
BPLP and Allied will share in cash flow and proceeds from any capital
transaction in proportion to their respective residual membership interests.

     In connection with the acquisition of Citigroup Center, BPLP has entered
into agreements with Allied that generally provide that, for a period of fifteen
years, BPLP may not sell or otherwise transfer the assets received in the
acquisition of Citigroup Center without the consent of Allied and will maintain
agreed upon levels of recourse or other indebtedness outstanding and available
to be guaranteed by Allied.  In addition, in connection with the transaction,
Allied acquired 26,821 common units of limited partnership of BPLP, valued at
approximately $1 million on the date of issuance (based on a price of $37.28 per
common unit, the average closing price of a share of common stock of the Company
during the ten trading days preceding the closing).  The common units may be
redeemed by the holder for cash equal to the then current value of a share of
common stock of the Company or, at the Company's election, for one share of
common stock of the Company.
