Stamps.com Stockholders Vote in Favor of Measure to Protect $95 Million Tax Asset

Stamps.com® (Nasdaq:STMP), the intelligent online postage alternative to a postage meter, today announced that the previously proposed restrictions on transfer of shares of its stock (the “NOL Protective Measures”) became effective today. These measures, designed to protect the Company’s significant tax net operating losses, were approved by 98% of the stockholders who voted on the matter at the annual meeting on May 22, 2008.

Under the new NOL Protective Measures, there is no change to the way that existing Stamps.com shares are held or traded, but all shareholders must now comply with the following:

• Any person, company or investment firm which wishes to become a “5% shareholder” of Stamps.com, must first obtain a waiver from the Company’s board of directors.
• Any person, company or investment firm which is already a “5% shareholder” of Stamps.com cannot make any additional purchases of Stamps.com stock without a waiver from the Company’s board of directors.
• Stockholders of Stamps.com who are not a “5% shareholder”, and do not wish to become a “5% shareholder”, do not need do anything at this time.
• Because the ownership calculations can be complicated, Stamps.com strongly urges that any stockholder contemplating owning more than 775,000 shares contact the Company before doing so.

Stamps.com currently has approximately $250M in Federal NOLs and $150M in State NOLs, with a potential value of up to $95M in tax savings over the next 15 years. The value of these NOLs could be significantly impaired unless the Company avoids potential transfers of its stock that could trigger such an “ownership change” under Section 382. For more details about the NOL Protective Measures, please see Proposal 2 in the Proxy Statement for the 2008 Annual Meeting of Stockholders of Stamps.com, which is available at sec.gov.
