LEAP Acquisition Corporation (the “Offeror”), a wholly-owned subsidiary of LaunchEquity Acquisition Partners, LLC Designated Series Education Partners (“Parent”) and sponsored entity of LaunchEquity Partners, LLC (“LaunchEquity”), and MakeMusic, Inc. (NASDAQ: MMUS) (“MakeMusic”), announced today that Offeror has extended the previously announced cash tender offer for all outstanding MakeMusic shares (the “Offer”) until midnight, New York City time, on April 30, 2013, unless further extended or earlier terminated.

The Depositary has informed the Offeror that, as of 5:00 p.m., New York City time, today, April 18, 2013, 2,984,666 shares of common stock have been validly tendered and not validly withdrawn (including 16,367 shares of common stock tendered pursuant to notices of guaranteed delivery). The 2,984,666 shares of common stock along with the 1,362,829 shares of common stock currently owned by Parent represent approximately 88.6% of MakeMusic’s issued and outstanding shares of common stock.

On April 16, 2013, the Fourth Judicial District Court of Minnesota ordered that, amongst other things, the claims contained in the amended and restated complaint of the plaintiff in Dr. Ezekiel Kruglick v. MakeMusic, Inc., et al. be stayed pending the investigation and recommendation of a special litigation committee appointed by MakeMusic’s Board of Directors. The Offer is being extended to allow additional time for such special litigation committee to conclude its investigation and make its determination.

Except as set forth herein, the complete terms and conditions of the Offer remain the same as set forth in the Offer to Purchase dated March 22, 2013, as amended, and the related letter of transmittal.

LaunchEquity, Offeror and Parent will amend their Tender Offer Statement, as amended, filed with the Securities and Exchange Commission (the “SEC”) to reflect this extension.
