Cashless Exercise. On any exercise of this Warrant, in lieu of payment of the aggregate Exercise Price in the manner specified in Section 2.1 above (but otherwise in accordance with the requirements of such Section), Holder may elect to surrender to the Company Shares having an aggregate value equal to the aggregate Exercise Price. If Holder makes such election, the Company shall issue to Holder such number of fully paid and non-assessable Shares determined by the following formula:

Exercise Price. The exercise price per Warrant Share under this Warrant shall be $33.08, subject to adjustment hereunder (the “Exercise Price”).

Cashless Exercise. If at any time after the six month anniversary of the date of the Purchase Agreement, there is no effective Registration Statement registering, or no current prospectus available for, the resale of the Warrant Shares by the Holder, then this Warrant may also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the Holder shall be entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing ​ by (A), where:

Partial Exercise. Subject to the restrictions in Section 3 hereof, this Purchase Warrant may be exercised in whole or in part. In the event of the exercise hereof in part only, upon surrender of this Purchase Warrant for cancellation, the Company shall cause to be delivered to the Holder without charge a new Purchase Warrant of like tenor to this Purchase Warrant in the name of the Holder evidencing the right of the Holder to purchase the number of Shares purchasable hereunder as to which this Purchase Warrant has not been exercised.

Exercise Consideration. Subject to Section 5(f) and Section 7(b), the consideration due upon settlement of the exercise of each Warrant will consist of the following:

Partial Exercise. An exercisable Option may be exercised in whole or in part. However, an Option shall not be exercisable with respect to fractional shares and the Administrator may require that, by the terms of the Option, a partial exercise must be with respect to a minimum number of Shares.
