On September 12, 2012, in connection with resuming its current rights offering (the “Rights Offering”), Motricity, Inc. (the “Company”) obtained a limited waiver from High River Limited Partnership (“High River”) providing that the Rights Offering does not trigger repayment of the $20 million secured term loan from High River, evidenced by that certain Amended and Restated Promissory Note, dated February 28, 2012, as amended on May 10, 2012 (the “Note”), as long as the Rights Offering is consummated on or prior to October 31, 2012. Except as set forth in the limited waiver, the Note and other Loan Documents (as defined therein) shall continue in full force and effect, each in accordance with its original terms.

High River is beneficially owned by Carl C. Icahn, a beneficial holder of approximately 16.5% of our outstanding securities. Brett C. Icahn, a director of the Company, is the son of Carl C. Icahn, and Hunter C. Gary, a director of the Company, is married to Carl C. Icahn’s wife’s daughter.

On September 13, 2012, the Company issued a press release announcing that it has resumed its rights offering that initially commenced on July 24, 2012 and was subsequently suspended on August 15, 2012 pending modification of the composition of the units to be offered.
