Under the terms of the agreement with Pontifax, Soligenix will have access to up to $20 million in convertible debt financing in three tranches, which will mature over a four and a half year period and have an interest-only period for the first two years. Upon the closing of this transaction, the Company has accessed the first tranche of $10 million, and has the option to draw the second tranche of $5 million at any time over the next 12 months and the third tranche of $5 million upon filing of the SGX301 new drug application, subject to certain conditions.

In addition, there can be no assurance as to the timing or success of the Phase 3 clinical trial of SGX942 (dusquetide) as a treatment for oral mucositis in patients with head and neck cancer receiving chemoradiation therapy, or any of our other clinical/preclinical trials.  Despite the statistically significant result achieved in the HYBRYTE Phase 3 clinical trial for the treatment of cutaneous T-cell lymphoma, there can be no assurance that a marketing authorization from the FDA or EMA will be successful.  Further, there can be no assurance that RiVax® will qualify for a biodefense Priority Review Voucher (PRV) or that the prior sales of PRVs will be indicative of any potential sales price for a PRV for RiVax®. Also, no assurance can be provided that the Company will receive or continue to receive non-dilutive government funding from grants and contracts that have been or may be awarded or for which the Company will apply in the future.
