Boston Properties, Inc. (NYSE: BXP), a real estate investment trust, reported

Funds from Operations (FFO) for the quarter ended September 30, 2012 were
$176.1 million, or $1.17 per share basic and $1.16 per share diluted. This
compares to FFO for the quarter ended September 30, 2011 of $190.3 million, or
$1.29 per share basic and $1.28 per share diluted. The results for the quarter
ended September 30, 2012 compared to 2011 were impacted by $0.03 per share of
losses on early extinguishments of debt and additional interest expense of
$0.06 per share. The weighted average number of basic and diluted shares
outstanding totaled 150,801,425 and 153,309,978, respectively, for the quarter
ended September 30, 2012 and 147,006,295 and 149,082,924, respectively, for
the quarter ended September 30, 2011.

The Company’s reported FFO of $1.16 per share diluted exceeded the guidance
previously provided of $1.13-$1.15 per share. The Company’s reported FFO
included the following items, among others, that were not reflected in the
guidance: $0.02 per share of improvements in portfolio operations and $0.01
per share less than expected of general and administrative expenses, offset
by($0.01) per share of acquisition-related expenditures.

Net income available to common shareholders was $57.8 million for the quarter
ended September 30, 2012, compared to $70.5 million for the quarter ended
September 30, 2011. Net income available to common shareholders per share
(EPS) for the quarter ended September 30, 2012 was $0.38 basic and $0.38 on a
diluted basis. This compares to EPS for the third quarter of 2011 of $0.48
basic and $0.48 on a diluted basis.

The reported results are unaudited and there can be no assurance that the
results will not vary from the final information for the quarter ended
September 30, 2012. In the opinion of management, all adjustments considered
necessary for a fair presentation of these reported results have been made.

As of September 30, 2012, the Company’s portfolio consisted of 152 properties,
comprised primarily of Class A office space, one hotel, three residential
properties and three retail properties, aggregating approximately 43.4 million
square feet, including eight properties under construction totaling 2.7
million square feet. In addition, the Company has structured parking for
vehicles containing approximately 15.2 million square feet. The overall
percentage of leased space for the 141 properties in service (excluding the
two in-service residential properties and the hotel) as of September 30, 2012
was 91.6%.

Significant events during the third quarter included:

  *On July 25, 2012, a joint venture in which the Company has a 50% interest
    partially placed in-service Annapolis Junction Building Six, a Class A
    office property with approximately 120,000 net rentable square feet
    located in Annapolis, Maryland. The property is currently 49% leased.
  *On August 24, 2012, the Company’s Operating Partnership used available
    cash to redeem the remaining $225.0 million in aggregate principal amount
    of its 6.25% senior notes due 2013. The redemption price was determined in
    accordance with the applicable indenture and totaled approximately $231.6
    million. The redemption price included approximately $1.5 million of
    accrued and unpaid interest to, but not including, the redemption date.
    Excluding such accrued and unpaid interest, the redemption price was
    approximately 102.25% of the principal amount being redeemed. The Company
    recognized a loss on early extinguishment of debt totaling approximately
    $5.2 million, which amount included the payment of the redemption premium
    totaling approximately $5.1 million.
  *On August 29, 2012, the Company acquired the development project located
    at 680 Folsom Street and 50 Hawthorne Street in San Francisco, California.
    When completed, the project will comprise approximately 522,000 net
    rentable square feet of Class A office and retail space. The project is
    approximately 85% pre-leased. The estimated project cost upon completion
    is approximately $340 million with initial occupancy expected in the first
    quarter of 2014. As part of the transaction, the Company also acquired the
    corner site of 690 Folsom Street, which is an adjacent parcel with a
    vacant 22,000 square foot, two-story structure that may be redeveloped in
    the future. The consideration paid by the Company to the seller consisted
    of approximately $62.2 million in cash and the issuance of 1,588,100
    Series Four Preferred Units of limited partnership interest in the
    Company’s Operating Partnership (the “Series Four Preferred Units”). The
    Series Four Preferred Units are not convertible into or exchangeable for
    any common equity of the Operating Partnership or the Company, have a per
    unit liquidation preference of $50.00 and are entitled to receive
    quarterly distributions of $0.25 per unit (or an annual rate of 2.0%). On
    August 31, 2012, a holder redeemed 366,573 Series Four Preferred Units for
    cash totaling approximately $18.3 million. In connection with the
    acquisition, the Company also assumed a $170.0 million construction loan
    commitment, although no amount is currently outstanding.

  *On September 4, 2012, the Company used available cash to repay the
    mortgage loan collateralized by its Sumner Square property located in
    Washington, DC totaling approximately $23.2 million. The mortgage
    financing bore interest at a fixed rate of 7.35% per annum and was
    scheduled to mature on September 1, 2013. The Company recognized a loss on
    early extinguishment of debt totaling approximately $0.3 million, which
    amount included a prepayment penalty totaling approximately $0.2 million.
  *On September 27, 2012, the Company’s Value-Added Fund completed the sale
    of its 300 Billerica Road property located in Chelmsford, Massachusetts
    for approximately $12.2 million, including the assumption by the buyer of
    $7.5 million of mortgage indebtedness. 300 Billerica Road is an
    approximately 111,000 net rentable square foot office building. Net cash
    proceeds totaled approximately $4.3 million, of which the Company’s share
    was approximately $2.8 million, after the payment of transaction costs.
    The Company’s share of the net proceeds included approximately $2.4
    million resulting from the Value-Added Fund’s repayment of a loan from the
    Company’s Operating Partnership. The Value-Added Fund recognized a gain on
    sale of real estate totaling approximately $1.0 million, of which the
    Company’s share was approximately $0.2 million and is included within
    income from unconsolidated joint ventures in the Company’s consolidated
    statements of operations.

Transactions completed subsequent to September 30, 2012:

  *On October 1, 2012, a joint venture in which the Company has a 30%
    interest partially placed in-service 500 North Capitol Street, NW, a Class
    A office redevelopment project with approximately 232,000 net rentable
    square feet located in Washington, DC. The property is currently 82%
    leased.
  *On October 4, 2012, the Company completed the formation of a joint venture
    which owns and operates Fountain Square located in Reston, Virginia,
    adjacent to the Company’s other Reston properties. Fountain Square is an
    office and retail complex aggregating approximately 764,000 net rentable
    square feet (approximately 811,000 net rentable square feet, as
    re-measured), comprised of approximately 522,000 net rentable square feet
    of Class A office space and approximately 242,000 net rentable square feet
    of retail space. The joint venture partner contributed the property valued
    at approximately $385.0 million and related mortgage indebtedness totaling
    approximately $211.3 million for a 50% interest in the joint venture. The
    Company contributed cash totaling approximately $87.0 million for its 50%
    interest, which cash was distributed to the joint venture partner. The
    Company is consolidating this joint venture. The mortgage loan bears
    interest at a fixed rate of 5.71% per annum and matures on October 11,
    2016. Pursuant to the joint venture agreement (i) the Company has rights
    to acquire the partner’s 50% interest and (ii) the partner has the right
    to cause the Company to acquire the partner’s interest on January 4, 2016,
    in each case at a fixed price totaling approximately $102.0 million in
    cash. The fixed price option rights expire on January 31, 2016.
  *On October 19, 2012, the Company formed a joint venture with an affiliate
    of Hines to pursue the acquisition of land in San Francisco, California
    which could support a 61-story, 1.4 million square foot office tower known
    as Transbay Tower. The purchase price is approximately $190 million, and
    the acquisition is expected to close in the first quarter of 2013. The
    Company has a 50% interest in the joint venture.

EPS and FFO per Share Guidance:

The Company’s guidance for the fourth quarter 2012 and full year 2013 for EPS
(diluted) and FFO per share (diluted) is set forth and reconciled below.
Except as described below, the estimates reflect management’s view of current
and future market conditions, including assumptions with respect to rental
rates, occupancy levels and the earnings impact of the events referenced in
this release and otherwise referenced during the conference call referred to
below. In addition, the estimates for the full year 2013 when compared to the
full year 2012 include, among other things, (1) the impact of the acquisition
of 100 Federal Street in Boston, Massachusetts and the Company’s acquisition
of a 50% interest in the joint venture that owns Fountain Square in Reston,
Virginia, which are expected to increase FFO by an aggregate of $0.11 per
share, (2) the placing in-service of four projects currently under
development, which are expected to increase FFO by an aggregate of $0.05 per
share and (3) improvement in the Company’s same property performance of 1.5%
to 2.5% generating $0.10 to $0.16 per share of incremental FFO. In addition,
the Company expects interest expense to be lower by $0.06 to $0.12 per share
due to lower average debt costs and increased capitalized interest on the
Company’s development projects. These items are offset by lower termination
income and the impact of lower occupancy in the Company’s New York City joint
venture properties of ($0.12) to ($0.18) per share. The estimates do not
include possible future gains or losses or the impact on operating results
from other possible future property acquisitions or dispositions, other
possible capital markets activity or possible future impairment charges. EPS
estimates may be subject to fluctuations as a result of several factors,
including changes in the recognition of depreciation and amortization expense
and any gains or losses associated with disposition activity. The Company is
not able to assess at this time the potential impact of these factors on
projected EPS. By definition, FFO does not include real estate-related
depreciation and amortization, impairment losses or gains or losses associated
with disposition activities. There can be no assurance that the Company’s
actual results will not differ materially from the estimates set forth below.

accordance with GAAP, including non-recurring items) for gains (or losses)
from sales of properties, impairment losses on depreciable real estate of
consolidated real estate, impairment losses on investments in unconsolidated
joint ventures driven by a measurable decrease in the fair value of
depreciable real estate held by the unconsolidated joint ventures, real estate
related depreciation and amortization, and after adjustment for unconsolidated
partnerships and joint ventures. FFO is a non-GAAP financial measure. The use
of FFO, combined with the required primary GAAP presentations, has been
fundamentally beneficial in improving the understanding of operating results
of REITs among the investing public and making comparisons of REIT operating
results more meaningful. Management generally considers FFO to be a useful
measure for reviewing our comparative operating and financial performance
because, by excluding gains and losses related to sales of previously
depreciated operating real estate assets, impairment losses and real estate
asset depreciation and amortization (which can vary among owners of identical
assets in similar condition based on historical cost accounting and useful
life estimates), FFO can help one compare the operating performance of a
company's real estate between periods or as compared to different companies.

Our computation of FFO may not be comparable to FFO reported by other REITs or
real estate companies that do not define the term in accordance with the
current NAREIT definition or that interpret the current NAREIT definition
differently.

FFO should not be considered as an alternative to net income attributable to
Boston Properties, Inc. (determined in accordance with GAAP) as an indication
of our performance. FFO does not represent cash generated from operating
activities determined in accordance with GAAP, and is not a measure of
liquidity or an indicator of our ability to make cash distributions. We
believe that to further understand our performance, FFO should be compared
with our reported net income attributable to Boston Properties, Inc. and
considered in addition to cash flows in accordance with GAAP, as presented in
our consolidated financial statements.

(2) Real estate depreciation and amortization consists of depreciation and
amortization from the Consolidated Statements of Operations of $111,360,
$108,674, $331,943 and $327,526, our share of unconsolidated joint venture
real estate depreciation and amortization of $21,664, $25,633, $68,298 and
$79,378, and depreciation and amortization from discontinued operations of $0,
$821, $1,040 and $2,477, less corporate-related depreciation and amortization
of $331, $351, $1,068 and $1,005 for the three and nine months ended September
30, 2012 and 2011, respectively.
