PCE Pacific Office Properties Trust,

Pacific Office Properties Trust, Inc. (NYSE Amex: PCE), a West Coast office real estate investment trust (REIT), today announced its financial results for the quarter ended March 31, 2011.

Company Highlights and Subsequent Events

Effective as of February 1, 2011, the Company internalized its management by acquiring its former advisor, and became self-managed and self-advised.

Subsequent to March 31, 2011, the Company formed two joint ventures with Angelo, Gordon & Co., a privately held investment manager with approximately $23 billion of assets under management. The joint ventures were formed to own two separate office properties, the City Square Office Towers in Phoenix, Arizona and the Pacific Business News Building, in Honolulu, Hawaii.

Subsequent to the formation of the joint venture to own the Pacific Business News Building, $11.6 million of matured debt secured by the Pacific Business News Building and outstanding on the Company’s balance sheet as of March 31, 2011, was repaid at a discount after negotiations with the lender. The Company was not obligated to pay default penalties and interest.

Subsequent to the formation of the joint venture to own the City Square Office Towers, $25.3 million of matured mezzanine debt secured by ownership interests in the City Square Office Towers and outstanding on the Company’s balance sheet as of March 31, 2011, was repaid at a discount after negotiations with the lender. The Senior Note of $27.5 million secured by the City Square Office Towers was extended to June 15, 2011. The joint venture is in negotiations with other lenders to refinance the senior note and expects to repay the debt in full.

Default interest and penalties totaling $0.5 million related to the matured debt and recorded by the Company in the first quarter 2011 were subsequently abated as part of the negotiated debt repayments.

The Company reported Funds from Operations (FFO) attributable to common stockholders for the quarter ended March 31, 2011 of $(0.8) million, or $(0.04) per diluted share.

The Company also incurred residual expenses of $0.4 million in abandoned offering costs. In addition, the Company recorded default interest and penalties related to the Company’s Pacific Business News Building and City Square mezzanine loans of approximately $0.1 million and $0.4 million, respectively. As noted above, subsequent to March 31, 2011, the Company contributed both properties into joint ventures and both loans were repaid at a discount. The Company was not obligated to pay the accrued default interest and penalties.

Explanation of Notations

(1) FFO is a widely recognized measure of REIT performance. The National Association of Real Estate Investment Trusts, or NAREIT, has provided a recommendation on how REITs should define FFO. NAREIT suggests that FFO be defined as net income (loss) attributable to stockholders (as computed in accordance with GAAP), excluding gains (or losses) from dispositions of property, extraordinary items, real estate-related depreciation and amortization (including capitalized leasing expenses, tenant allowances or improvements and excluding amortization of deferred financing costs) and after adjustments for unconsolidated partnerships and joint ventures. We calculate FFO in accordance with NAREIT guidelines. Management uses FFO as a supplemental performance measure because, in excluding real estate-related depreciation and amortization, gains (or losses) from property dispositions and extraordinary items, it provides a performance measure that, when compared year over year, captures trends in occupancy, rental rates and operating costs. We also believe that, as a widely recognized measure of the performance of REITs, FFO will be used by investors as a basis to compare our operating performance with that of other REITs.

However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our properties that result from use or market conditions nor the level of capital expenditures and leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effect and could materially impact our results from operations, the utility of FFO as a measure of our performance is limited. Other equity REITs may not calculate FFO in accordance with the NAREIT definition and, accordingly, our FFO may not be comparable to such other equity REITs’ FFO. As a result, FFO should be considered only as a supplement to net income (loss) as a measure of our performance. FFO should not be used as a measure of our liquidity, nor is it indicative of funds available to fund our cash needs, including our ability to pay dividends or make distributions. FFO also should not be used as a supplement to or substitute for cash flow from operating activities (computed in accordance with GAAP).

(2) AFFO is a non-GAAP financial measure we believe is a useful supplemental measure of our performance. We compute AFFO by adding to FFO nonrecurring items, straight-line rent adjustments (straight-line ground rent expense minus straight-line rent revenue), the amortization of interest rate contracts, loan premium and prepaid financing costs, non-cash compensation expense, and interest expense deferred on unsecured notes and then subtracting from FFO the amortization of acquired above- and below-market leases and recurring capital expenditures, tenant improvements and leasing commissions. AFFO is not intended to represent cash flow for the period, and it only provides an additional perspective on our ability to fund cash needs and make distributions to shareholders by adjusting the effect of the non-cash items included in FFO, as well as recurring capital expenditures and leasing costs. We believe that net income or loss is the most directly comparable GAAP financial measure to AFFO. We also believe that AFFO provides useful information to the investment community about the Company’s financial position as compared to other REITs since AFFO is a widely reported measure used by other REITs. However, other REITs may use different methodologies for calculating AFFO and, accordingly, our AFFO may not be comparable to other REITs.

(3) The weighted average number of common shares and common share equivalents outstanding – diluted includes common unit limited partnership interests in our Operating Partnership.

Our outstanding preferred unit interests in our Operating Partnership are convertible into common unit limited partnership interests in our Operating Partnership, but no earlier than the date an underwritten public equity offering of our common stock in an amount equal to or greater than $75 million is consummated, which is a contingent event as of March 31, 2011. These common unit interests will become exchangeable for shares of our Listed Common Stock one year after such conversion. Our outstanding preferred unit interests at March 31, 2011 represent 32,597,528 common share equivalents, on an as-if converted basis, and any impact related to these outstanding preferred unit interests have not been included in our calculation of diluted earnings per share or FFO per share, including our calculation of the weighted average number of common and common equivalent shares outstanding, in accordance with GAAP.

Our Senior Common Stock may be exchanged, at the option of the holder, for shares of our Listed Common Stock after the fifth anniversary of the issuance of such shares of Senior Common Stock. The exchange ratio is to be calculated using a value for our Listed Common Stock based on the average of the trailing 30-day closing price of the Listed Common Stock on the date the shares are submitted for exchange, but in no event less than $1.00 per share, and a value of Senior Common Stock of $10.00 per share. Based on a 30-day average Listed Common Stock share price of $2.25 for the month ended March 31, 2011, the exchange ratio as of March 31, 2011, on an as-if converted basis was 4.44. The weighted average number of Senior Common shares outstanding for the three months ended March 31, 2011 was 2,417,867, resulting in 10,723,282 of potentially dilutive common share equivalents outstanding for the three months ended March 31, 2011.

Assuming the full conversion of our outstanding preferred unit interests and our Senior Common Stock, our FFO per share, on a fully diluted basis, would have been $0.00 and our AFFO per share, on a fully diluted basis, would have been $0.02, for the three months ended March 31, 2011. Assuming the full conversion of our outstanding preferred unit interests, our FFO per share and AFFO per share, on a fully diluted basis would have been $0.04 and $0.05, respectively, for the three months ended March 31, 2010. Assuming the full conversion of our outstanding preferred unit interests and our Senior Common Stock, our FFO excluding non-recurring items would have been $0.01 for the three months ended March 31, 2011. There would be positive FFO on a fully diluted per share basis for the three months ended March 31, 2011 due to the assumption that the $0.6 million of distribution to preferred unitholders and the Senior Common Stock dividend of $0.4 million would cease upon conversion to shares of Listed Common Stock. Assuming the full conversion of our outstanding preferred unit interests, our FFO excluding non-recurring items would have been $0.04 for the three months ended March 31, 2010.
