8.  Deferred Research and Development Arrangements

Rexgene Biotech Co., Ltd.

In 2003, the Company entered into a collaborative research agreement with Rexgene Biotech Co., Ltd. (“Rexgene”), a shareholder.  Rexgene is engaged in the development of pharmaceutical products in Asia and has agreed to assist the Company with the research, development and clinical trials necessary for registration of the Company’s drug candidate, Archexin, in Asia.  This agreement provides Rexgene with exclusive rights to license, sublicense, make, have made, use, sell and import Archexin in Asia.  In accordance with the agreement, Rexgene paid the Company a one-time fee of $1,500,000 in 2003.  The agreement terminates at the later of 20 years or the term of the patent.  The amortization reduces research and development expenses for the periods presented. 
 

The Company is using 20 years as its basis for recognition and accordingly, research and development expenses were reduced by $75,000 for the years ended December 31, 2013 and 2012, respectively.  The remaining $675,000 and $750,000 to be amortized at December 31, 2013 and December 31, 2012, respectively, are reflected as deferred research and development arrangements on the balance sheet.  The payment from Rexgene is being used in the cooperative funding of the costs of development of Archexin. Royalties of 3% of net sales of licensed products will become payable to the Company on a quarterly basis once commercial sales of Archexin begin in Asia.  The product is still under development and commercial sales in Asia are not expected to begin until at least 2015.  Under the terms of the agreement, Rexgene does not receive royalties on the Company’s net sales outside of Asia.

Teva Pharmaceutical Industries, Ltd.

On September 21, 2009, the Company closed on a securities purchase agreement (the “Purchase Agreement”) with Teva Pharmaceutical Industries Limited (“Teva”), and contemporaneous with the execution and delivery of this agreement, the parties executed a research and exclusive license option agreement (the “RELO Agreement”) pursuant to which the Company agreed to use proceeds from the issuance and sale of shares to Teva to fund a research and development program for the pre-clinical development of RX-3117.  On November 27, 2012, the Company and Teva entered into a second amendment to the RELO Agreement, pursuant to which Teva provided the Company with an additional $926,000 of research funding for the development of RX-3117, which was recorded as restricted cash on the Company’s balance sheet.  The contribution from the second amendment was recorded in deferred research and development arrangements on the balance sheet.  Costs incurred for the development of RX-3117 are paid from restricted cash, reduce the deferred research and development arrangement and therefore are not an expense in the Company’s statement of operations.  As of December 31, 2013 and December 31, 2012, the Company had proceeds remaining of $158,630 and $876,000, respectively, which are included in restricted cash and  deferred research and development arrangements on the balance sheet.  During the years ended December 31, 2013 and 2012, $717,370 and $50,000, respectively, were reduced from the deferred research and development arrangement, either for costs incurred for the development of RX-3117, or returned to Teva as funds not allocated to specific projects.  On August 28, 2013, the Company announced that Teva had decided not to exercise its option to license RX-3117, and as a result, the RELO Agreement was terminated.  The proceeds remaining from the restricted cash will be used to pay for expenses not yet incurred.
