OEM Partner Agreements

The Company sells all of its generators and a majority of its neurosurgery instruments and accessories to two U.S. based national and international OEM partners as described below:

Codman

In the neurosurgical market, the bipolar electrosurgical system manufactured by Valley Forge prior to the merger has been sold for over 30 years through a series of distribution agreements with Codman, an affiliate of Johnson & Johnson. On April 2, 2009, the Company executed a new, three-year distribution agreement with Codman for the continued distribution by Codman of certain bipolar generators and related disposables and accessories, effective January 1, 2009. In addition, the Company entered into a new, three-year license agreement, which provides for the continued licensing of the Company’s Malis^® trademark to Codman for use with certain Codman products, including those covered by the distribution agreement. Both agreements expired on December 31, 2011 and have renewed for three years. In December 2010, Codman elected to exercise its option of exclusive distribution with respect to the bipolar generators and related disposables and accessories in the fields of neurocranial and neurospinal surgery. On December 16, 2014, the Company executed an amendment to the agreements effective as of December 9, 2014. The amendment extends the terms of the agreements until December 31, 2015. All other provisions remain unchanged.

On November 16, 2009, the Company announced the signing of an addendum to its three-year agreement with Codman. Under the terms of the revised agreement, Codman has the exclusive right to market and distribute the Company’s Malis^® branded disposable bipolar forceps produced by Synergetics. Codman began distribution of the disposable bipolar forceps on December 1, 2009, domestically, and on February 1, 2010, internationally.

Total sales to Codman and its respective percent of the Company’s net sales for the years ended July 31, 2015, 2014 and 2013, including the historical sales of generators, accessories and disposable cord tubing that the Company has supplied in the past, as well as the disposable bipolar forceps sales resulting from the addendum to the existing distribution agreement, were as follows (dollars in thousands):

On March 31, 2010, the Company entered into a supply agreement with Stryker pursuant to which the Company agreed to supply Stryker with disposable ultrasonic aspirator instrument tips and certain other consumable products used in conjunction with Stryker’s ultrasonic aspirator console and handpieces. The agreement expires on March 31, 2019.
