Abraham, Fruchter & Twersky, LLP Announces That It Has Been Retained to File a Class Action Lawsuit Against Oppenheimer Funds Re

  Abraham, Fruchter & Twersky, LLP has been
retained to file a class action lawsuit against Oppenheimer Funds on behalf
of purchasers of the Rochester National Municipals Fund ("Rochester" or the
"Fund") (NASDAQ: ORNAX) (NASDAQ: ORNBX) (NASDAQ: ORNCX) from March 13, 2006
through October 21, 2008 (the "Class Period").  A lawsuit has already been
filed in the United States District Court for the District of Colorado.

The complaint filed charges Oppenheimer, the Fund and certain of its Trustees with violations of the Securities Act of 1933. The suit claims that the registration statements and prospectuses used to sell shares in the Fund contained materially false and misleading statements about the risks of investing in the Fund. The lawsuit identified the following funds as affected: A Shares (ORNAX), B Shares (ORNBX) and C Shares (ORNCX).

On October 21, 2008, Rochester filed a Prospectus Supplement which alerted investors of the true liquidity risks of the Fund's investments. The Fund closed at $6.59 per share later that day, representing a 49% decline from the Class Period high of $13.00 per share.

Plaintiffs seek to recover damages on behalf of all those who purchased shares of Rochester National Municipals Fund from March 13, 2006 through October 21, 2008. Abraham, Fruchter & Twersky, LLP has extensive experience in securities class action cases, having been ranked among the leading class action law firms in terms of recoveries achieved by a survey of class action law firms conducted by Institutional Shareholder Services.
