RE: Additional agreement (“Addendum”) in connection with that certain Reimbursement Agreement; General Security Agreement of even date herewith (the “Reimbursement Agreement”).

 

Gentlemen:

In order to further induce sanofi-aventis, a French Société Anonyme (the “Secured Party”) to enter into the transactions contemplated by the Reimbursement Agreement with SCYNEXIS, Inc., a Delaware corporation (the “Debtor”), and in exchange for the premises, covenants and agreements set forth therein, all of which Debtor recognizes as adequate consideration, the Debtor hereby covenants and agrees that, if the Secured Party has not been released as Guarantor pursuant to, and as defined in, that certain Stand-Alone First Demand Guarantee of even date herewith between HSBC Bank USA, National Association (“HSBC”) and the Secured Party (the “Guarantee Agreement”), prior to Debtor’s receipt of proceeds from any of the following events:

 

  1) Initial Public Offering: the closing of the Debtor’s initial public offering of its equity interests to an effective registration statement under the Securities Act of 1933, as such Act may be amended from time to time (an “IPO”), resulting in at least $30,000,000 of proceeds net of the underwriting discounts and commissions;

 

  2) Follow-on Offering: in the event where the IPO does not result in at least $30,000,000 of net proceeds, the closing of any subsequent public offering of Debtor’s equity interests (each, a “Follow-on Offering”) wherein the aggregate amount of the IPO and Follow-on Offering(s) results in at least $30,000,000 of proceeds, net of the underwriting discounts and commissions;

 

  3) Private Placement: the closing of an investment, in one or a series of transactions, in the Debtor resulting in at least $30,000,000 of proceeds net of any placement discounts and commissions (a “Private Placement”) (for purposes of clarification but not limitation, an issuance by Debtor of promissory notes that are convertible into equity shall qualify as an “investment” pursuant to the definition of “Private Placement”);


  4) Combination: Any combination of the foregoing resulting in aggregate in at least $30,000,000 of proceeds net of the underwriting discounts and commissions or the placement discounts and commissions, as applicable; or

 

  5) License Agreement: Debtor’s entry into a Transaction Agreement (as defined in the Right of First Negotiation Agreement by and between the Secured Party and Debtor) resulting in any amount of cash proceeds (the proceeds from each of events 1-5, the “Net Proceeds”),

then the Debtor will inform the Secured Party prior to the consummation of any of the events 1-5 contemplated herein and will either (i) subject to prior written request of the Secured Party, initially apply the Net Proceeds (before the application of such Net Proceeds to any other purpose) to repay all amounts then owing to HSBC that are required to fully release the Secured Party from its obligations pursuant to the Guarantee Agreement, or (ii) otherwise provide the Secured Party with a waiver from HSBC, in writing and in a form acceptable to the Secured Party, fully releasing the Secured Party as Guarantor pursuant to the Guarantee Agreement.

This Addendum shall be governed by the laws of the State of North Carolina in all respects, including matters of construction, validity and performance (without regard to its principles of conflicts of law). None of this Addendum’s terms or provisions may be waived, altered, modified, limited or amended except by a written agreement expressly referring hereto and to which Secured Party consents in writing. No provision of this Addendum shall in any way inure to the benefit of any third person so as to constitute to any such person a third-party beneficiary of this Addendum or otherwise give rise to any cause of action in any person not a party hereto. This Agreement embodies the entire understanding between the Secured Party and the Debtor with respect to the subject matter herein, and supercedes any and all prior understandings and agreements, oral or written, relating to the subject matter. The rights granted to Secured Party herein shall be supplementary and in addition to those granted in any other agreements. This Agreement binds the Debtor, its successors and assigns, and inures to the benefit of the Secured Party, its successors and assigns.
