In exchange, Pharmsynthez granted the Issuer an exclusive license to use any pre-clinical and clinical data developed by Pharmsynthez, within the scope of the Pharmsynthez Arrangement, and to engage in further research, development and commercialization of drug candidates outside of certain territories at the Issuer’s own expense.

In July 2015, the Issuer entered into a Securities Purchase Agreement with Pharmsynthez providing for the issuance of $3.0 million of convertible promissory note and warrants to purchase an aggregate of 606,062 Shares. These warrants have a five year term and are exercisable at the lesser of $6.60 per share and 120% of the price per share in the Issuer’s next capital sale of at least $7 million (the “Exercise Price”).

In November 2015, the Issuer entered into an Asset Purchase Agreement (the “APA”) with Pharmsynthez. The APA provided for the transfer to the Issuer of certain intellectual property rights with respect to the immunomodulatory drug candidate XBIO-101. In April 2016, the Issuer completed the purchase of the intellectual property rights associated with the APA and issued 3,045,455 Shares pursuant to the APA.

The APA also provided for the Issuer’s issuance of certain convertible promissory notes and warrants to purchase Shares. During the quarter ended March 31, 2016, the Issuer issued $3.5 million of convertible promissory notes to Pharmsynthez receiving $3.5 million in cash proceeds. In April 2016, Pharmsynthez converted all of its convertible promissory notes (both the July 2015 note and the Q1 2016 notes) and associated interest into 1,373,036 Shares. As such, the Issuer issued to Pharmsynthez 1,373,036 Shares in connection with conversion of the convertible notes, which amount, together with the 3,045,455 Shares in connection with the closing of the APA, resulted in an aggregate of 4,418,491 new Shares being issued to Pharmsynthez.

In connection with the Issuer’s issuance of the convertible promissory notes in March 2016, the Issuer issued to Pharmsynthez warrants to purchase 353,540 Shares at the Exercise Price.

In return, SynBio granted the Issuer an exclusive license to use the pre-clinical and clinical data generated by SynBio in certain agreed upon products and engage in the development of commercial drug candidates.

The Co-Development Agreement provides for the sale of certain research supplies between each party to the agreement. For the years ended December 31, 2016 and 2015, the Issuer did not recognize any supply service revenues from sales to SynBio about the Co-Development Agreement.

Concurrent with entering into the Co-Development Agreement, the Issuer entered into a stock subscription agreement with SynBio pursuant to which the Issuer sold SynBio approximately 1.8 million Shares.

In furtherance of the Issuer’s co-development clinical objectives, on December 31, 2014 the Issuer granted SynBio a warrant to purchase 204,394 Shares that contain vesting triggers based on the achievement by SynBio of certain clinical development objectives within specific timeframes with an exercise price of $25.41 per share (the “SynBio 2014 Warrant”). The SynBio 2014 Warrant expires on December 30, 2019.

On September 23, 2016, SynBio exchanged 970,000 Shares for an equal number of Shares of Series A Preferred Stock.

Effective October 26, 2016, the Issuer entered into a voting agreement with SynBio whereby SynBio agreed to vote their Shares in the same proportion as the Shares held by non-affiliates on all matters subject to stockholder approval for a period of one year. A copy of this voting agreement is attached hereto as Exhibit B.

In May 2011, the Issuer received a short-term unsecured loan facility of up to $1.7 million from SynBio, of which $0 was outstanding as of December 31, 2016. In connection with the APA, the Issuer made a series of payments during 2016 totaling $323,640 to creditors. Pursuant to the APA such payments are considered direct offsets to the loan with SynBio. The loan had an interest rate of 8.04% per annum as of the date of grant, with interest payable upon repayment of the loan, which was to be seven months after the closing date of the loan. In December 2016, the Issuer entered into an agreement with SynBio and Pharmsynthez, which settled all amounts owed by the Issuer on the SynBio loan; for services provided to the Issuer in connection with the XBIO-101 Phase 2 project; and the purchase of drug candidate supply sufficient to meet the needs of the XBIO-101 Phase 2 clinical trial.
