Exhibit 99.1

FSP Phoenix Tower Corp.

FSP Phoenix Tower Corp. (the "Company") has declared a dividend in the amount of $666 per share of preferred stock, representing property operations for the quarter ended March 31, 2011. The dividend will be payable on May 31, 2011 and will be distributed by the Company’s transfer agent, American Stock Transfer & Trust Co. (“AST”). NOTE: if your investment is in a retirement account, the dividend will be sent to your custodian or plan administrator.

The Company’s property, a 34-story, multi-tenant Class "A" office building containing approximately 629,054 square feet, is located in Houston, Texas, and, as of March 31, 2011, was approximately 70% leased, a 2% increase from the prior quarter. The increase in occupancy during the first quarter was attributable to new tenants and expansion of an existing tenant.

As reported last quarter, the Company entered into a $2.8 million dollar contract with Thyssen Krupp Elevator Corporation to modernize 21 elevators serving the property. The project commenced during the fourth quarter of 2010, is on budget and remains on target to be completed by the end of this year. Management believes that the elevator modernization project should reduce operating costs, improve the overall performance of elevator service, and provide yet another positive attribute to entice prospective tenants.

During the first quarter, occupancy within the submarket in which the property competes decreased slightly (less than 0.5%) after several consecutive quarters of improvement. Rental rates remained relatively flat during the same period. Management continues to believe that the position of the property within the city’s office market is strong, and is optimistic that the existing vacant space will ultimately be leased to new tenants. Management remains confident that the repositioned Phoenix Tower is a much more desirable office environment for prospective and existing tenants. However, until the existing vacancy is re-leased, it is likely that we will continue to experience lower occupancy rates and, as a consequence, lower dividend yields.

The Texas Workforce Commission reported that unemployment in the Houston area was 8.3% in March, unchanged from December 2010. We continue to believe that vacancy and unemployment rates will likely remain flat or increase slightly in Houston before conditions start to improve. Additional jobs in Houston could, over time, improve the pace of leasing activity. Management believes that the global and local economic downturns continue to prolong the time that it takes to re-lease the property.

As of the date of this letter, a total of $8.6 million has been drawn down on the $15 million revolving line of credit from Franklin Street Properties Corp. to cover capital improvement costs, as well as tenant improvement and commission costs. At the current level of occupancy, the property is projected to produce enough income going forward to cover operating expenses and interest on an annual basis.

The Company’s quarterly filing on Form 10-Q will be submitted to the SEC within approximately 45 days after the end of the quarter, and you will be able to access the document via the SEC’s website. To view Company filings with the SEC, access the following link:
