Note 7 - Commitments and Contingencies

Leases

We lease our office in Maryland under a 10 year operating lease, which commenced on May 1, 2007 and will end on May 31, 2017. Remaining annual minimum payments of approximately $0.4 million are due in 2017. Minimum payments have not been reduced by the minimum sublease rentals of $0.1 million due in the future under noncancellable subleases.

For the years ended December 31, 2016, 2015 and 2014, total rent expense under the operating lease agreement approximated $0.8 million, $0.7 million and $0.8 million, respectively. Total rent expense is allocated to research and development and general and administrative expenses on the consolidated statements of operations.

On September 2, 2015, the Company entered into a sublease agreement with a third party with respect to a portion of its leased office space at an amount less than the Company’s leased amount. As a result, we realized a loss of $0.4 million in restructuring expense on our consolidated statements of operations for the year ended December 31, 2015.

The present value at December 31, 2016 of the Company’s remaining net lease liability for the subleased office space (net of the sublease rental income) is approximately $0.1 million and is reflected on the balance sheet as accrued restructuring expenses – current.

License Agreements

In connection with an acquisition in 2008, we acquired license agreements with The Defence Science and Technology Laboratory of the United Kingdom Ministry of Defence, or DSTL, for the rights to certain technologies. These agreements allow for the licensing of certain patents and technology necessary to perform development of the rPA vaccine program as required under the Company’s government contracts. Upon commercialization, the license agreements require that we make royalty payments equal to a specified percentage of future sales of products for both government procurement and commercial markets. No royalty payments on these licenses have been incurred.

In 2012 we entered into a commercial licensing agreement allowing for the licensing of certain patent and other intellectual property rights from a research company related to BChE. The agreement includes certain annual maintenance and other development milestone payments. Upon commercialization, the license agreement requires royalty payments equal to a specified percentage of future sales of products for both government procurement and commercial market sales subject to the license through the expiration of the licensed patents. Maintenance fees of $0.1 million were incurred during each of the years ended December 31, 2015 and 2014. Maintenance fees of $0.04 million were incurred during the year ended December 31, 2013. This agreement was terminated in 2015.

On July 6, 2015, we signed a license agreement with ImmunoVaccine Technologies (“IMV”) for the exclusive use of the DepoVax^TM vaccine platform (“DPX”), to develop an anthrax vaccine utilizing PharmAthene’s rPA. On June 23, 2016, we terminated this license agreement.

SIGA Litigation

In December 2006, we filed a complaint against SIGA in the Delaware Court of Chancery. The complaint alleged, among other things, that we have the right to license exclusively the development and marketing rights for SIGA’s drug candidate, Tecovirimat, also known as ST-246^®, pursuant to a merger agreement between the parties that was terminated in 2006. The complaint also alleged that SIGA failed to negotiate in good faith the terms of such a license pursuant to the terminated merger agreement with us.

In September 2014, SIGA filed a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code in the U.S. Bankruptcy Court for the Southern District of New York (the “Bankruptcy Court”). SIGA’s petition for bankruptcy initiated a process whereby its assets were protected from creditors, including PharmAthene.

In January 2015, after years of litigation, the Delaware Court of Chancery issued a Final Order and Judgment, finding that we were entitled to receive a lump sum award of $194.6 million, or the Total Judgment, comprised of (1) expectation damages of $113.1 million for the value of the Company’s lost profits for Tecovirimat, plus (2) pre-judgment interest on that amount from 2006 and varying percentages of the Company’s reasonable attorneys’ and expert witness fees, totaling $81.5 million. Under the Final Order and Judgment, PharmAthene was also entitled to post-judgment simple interest.

On December 23, 2015, the Delaware Supreme Court affirmed the Delaware Court of Chancery's decision as a result of which, with additional post-judgment interest, if calculated based on the original decision, would provide for an estimated total award in excess of $205 million.

On April 8, 2016, the Bankruptcy Court entered an order confirming SIGA’s Plan effective April 12, 2016 which provides for among other things, the process by which SIGA may emerge from bankruptcy, which includes the process by which our Judgment may be satisfied.

We received approximately $217.1 million from SIGA during the year ended December 31, 2016, comprised of principal payments of approximately $208.7 million as final satisfaction of the judgment and approximately $8.4 million of payments calculated by SIGA as interest on the judgment, all of which has been recorded in other income – litigation on the consolidated statement of operations.

Government Contracting

Payments to the Company on cost-plus-fee contracts are provisional. The accuracy and appropriateness of costs charged to U.S. Government contracts are subject to regulation, audit and possible disallowance by the Defense Contract Audit Agency, or DCAA, and other government agencies such as BARDA. Accordingly, costs billed or billable to U.S. Government customers are subject to potential adjustment upon audit by such agencies. We have finalized incurred cost audits with DCAA for 2006 through 2011. BARDA audited indirect costs or rates charged by us on the SparVax^® contract for the years 2008 through 2014. As a result of the BARDA audits, we recorded additional revenue of $0.8 million and $5.8 million during the years ended December 31, 2016 and 2015, respectively.

Changes in government policies, priorities or funding levels through agency or program budget reductions by the U.S. Congress or executive agencies could materially adversely affect the Company’s financial condition or results of operations. Furthermore, contracts with the U.S. Government may be terminated or suspended by the U.S. Government at any time, with or without cause. Such contract suspensions or terminations could result in unreimbursable expenses or charges or otherwise adversely affect the Company’s financial condition and/or results of operations.

Registration Rights Agreements

We entered into a Registration Rights Agreement with the investors who participated in the July 2009 private placement of convertible notes and related warrants. We subsequently filed two registration statements on Form S-3 with the Securities and Exchange Commission to register the resale of the shares issuable upon conversion of the convertible notes and exercise of the related warrants, which have been declared effective. We are obligated to maintain the registration statements effective until the date when such shares (and any other securities issued or issuable with respect to or in exchange for such shares) have been sold or are eligible for resale without restrictions under Rule 144. The convertible notes were converted or extinguished in 2010. The warrants expired on January 28, 2015.

We have separate registration rights agreements with investors, under which we have obligations to keep the corresponding registration statements effective until the registrable securities (as defined in each agreement) have been sold, and under which we may have separate obligations to file registration statements in the future on either a demand or “piggy-back” basis or both.

Under the terms of the convertible notes, which were converted or extinguished in 2010, if after the 2nd consecutive business day (other than during an allowable blackout period) on which sales of all of the securities required to be included on the registration statement cannot be made pursuant to the registration statement (a “Maintenance Failure”), we will be required to pay to each selling stockholder a one-time payment of 1.0% of the aggregate principal amount of the convertible notes relating to the affected shares on the initial day of a Maintenance Failure. Our total maximum obligation under this provision at December 31, 2016, which is not probable of payment, would be approximately $0.2 million.

Following a Maintenance Failure, we will also be required to make to each selling stockholder monthly payments of 1.0% of the aggregate principal amount of the convertible notes relating to the affected shares on every 30th day after the initial day of a Maintenance Failure, in each case prorated for shorter periods and until the failure is cured. Our total maximum obligation under this provision, which is not probable of payment, would be approximately $0.2 million for each month until the failure, if it occurs, is cured.
