On March 12, 2015, the Compensation Committee of the Board of Directors (the “Board”) of Coronado Biosciences, Inc. (the “Company”) approved a deferred compensation plan (the “Plan”) for non-employee directors (“Participants”). The Plan, to be administered by the Compensation Committee, is intended to be a non-qualified benefit plan for purposes of the Employee Retirement Income Security Act of 1974, as amended.

Pursuant to the Plan, a Participant can defer all or a portion of Participant’s unearned annual fees, meeting fees, and committee fees, including restricted stock and restricted stock units. Deferred cash compensation will be converted into a number of stock units, determined based upon the closing price of the Company’s common stock on the date such fees would otherwise have been payable and placed into the Participant’s deferred compensation account (“Account”). Deferred restricted stock unit grants will be converted on a share-for-share basis on the date such restricted stock units would otherwise have been payable and placed into the Participant’s Account.

On the tenth business day of January of the year following the Participant’s termination of service on the Board due to resignation, removal, failure to be re-elected, or retirement, the amount of deferred compensation in the Participant’s Account will be distributed to the Participant in a lump sum payment of a number of shares of the Company’s common stock under the Company’s 2013 Stock Incentive Plan, as may be amended, equal to the number of whole stock units in the Account and cash in lieu of any fractional shares. Distributions from the Account may be accelerated in the event of the Participant’s death or upon a corporate transaction (as defined in the Plan).

The above description of the Plan is qualified in its entirety by reference to the full and complete terms of the Plan, which is filed as Exhibit 10.67 to this Current Report on Form 8-K.
