ASC 605 requires that four basic criteria must be met before revenue can be recognized: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services rendered; (3) consideration is fixed or determinable; and (4) collectability is reasonably assured.</font></div> <div style="TEXT-INDENT: 0pt; DISPLAY: block"><br /></div> <div style="TEXT-INDENT: 18pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="justify"><font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt">On February 4, 2013, Opexa entered into an Option and License Agreement (the “Merck Agreement”) with Ares Trading SA (“Merck”), a wholly owned subsidiary of Merck Serono S.A.  Pursuant to the terms, Merck has an option to acquire an exclusive, worldwide (excluding Japan) license of the Company’s Tcelna<font style="DISPLAY: inline; FONT-SIZE: 70%; VERTICAL-ALIGN: text-top">®</font> program for the treatment of multiple sclerosis (“MS”).  Tcelna is currently in a Phase IIb clinical trial in patients with Secondary Progressive MS (“SPMS”). The option may be exercised by Merck prior to or upon the Company’s completion of the Phase IIb Trial.</font></div> <div style="TEXT-INDENT: 0pt; DISPLAY: block"><br /></div> <div style="TEXT-INDENT: 18pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="justify"><font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt">Opexa received an upfront payment of $5 million for granting the option. If the option is exercised, Merck would pay the Company an upfront license fee of $25 million unless Merck is unable to advance directly into a Phase III clinical trial of Tcelna for SPMS without a further Phase II clinical trial (as determined by Merck), in which event the upfront license fee would be $15 million. After exercising the option, Merck would be solely responsible for funding development, regulatory and commercialization activities for Tcelna in MS, although the Company would retain an option to co-fund certain development in exchange for increased royalty rates.  The Company would also retain rights to Tcelna in Japan, certain rights with respect to the manufacture of Tcelna, and rights outside of MS.</font></div> <div style="TEXT-INDENT: 0pt; DISPLAY: block"><br /></div> <div style="TEXT-INDENT: 18pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="justify"><font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt">Opexa evaluated the Merck Agreement and determined that the $5 million upfront payment from Merck has stand-alone value. Opexa’s continuing performance obligations, in connection with the $5 million payment, include the execution and completion of the Phase IIb clinical trial in SPMS using commercially reasonable efforts at the Company’s own costs.  As a stand-alone value term in the Merck Agreement, the $5 million upfront payment is determined to be a single unit of accounting, and is recognized as revenue on a straight-line basis over the exclusive option period based on the expected completion term of the Phase IIb clinical trial in SPMS. Opexa includes the unrecognized portion of the $5 million as deferred revenue on the consolidated balance sheets.</font></div> <div style="TEXT-INDENT: 0pt; DISPLAY: block"><br /></div> <div style="TEXT-INDENT: 18pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="justify"><font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt"><font style="DISPLAY: inline; FONT-WEIGHT: bold"> Cash and Cash Equivalents</font>.  Opexa considers all highly liquid investments with an original maturity of three months or less, when purchased, to be cash equivalents.
