In the event that the Borrower fails to make such payment in full by such deadline, each Purchaser shall have the right to rescind and terminate any or all of this Agreement and the transactions contemplated hereby and/or to exercise any and all other rights and remedies available at law or in equity.

Section 1.02.    Exchange. In connection with closing on the date hereof of the New Financing, each Purchaser hereby agrees to exchange a portion of the principal amount of such Purchaser’s Notes for the issuance by the Borrower to such Purchaser of the applicable Exchange Shares (the “Exchange”), as follows:

(a)    Issuance of Shares. Pursuant to the Exchange, which shall be deemed effective and consummated immediately prior to the closing of the New Financing on the Closing Date, (i) the Borrower shall issue the DPDF Shares to DPDF and the DPDI Shares to DPDI, and, subject thereto and in exchange therefor, (ii) (A) the principal amount of DPDF’s Tranche 1 Note shall be deemed repaid by $1,398,000 and the principal amount of DPDI’s Tranche 1 Note shall be deemed repaid by $1,602,000, each such deemed repayment to be applied against, and reduce, the principal amount of each Purchaser’s Tranche 1 Note that the Borrower would, but for the consummation of the transactions contemplated by this Article I, be obligated to repay on August 31, 2019. The Borrower represents, warrants, covenants and agrees that, in reliance on the

2

Purchasers’ representations in Section 2.01(e), the Exchange Shares (X) will be freely transferable by the Purchasers, without restriction or limitation (including any volume limitation) under federal or state securities laws, pursuant to Rule 144 under the Securities Act, and (Y) will not contain or be subject to any legend or stop transfer instructions restricting the sale or transferability thereof.

(b)    Delivery of Exchange Shares. By no later than 4:00 p.m., New York City time, on the Closing Date, the Borrower shall cause the transfer agent for the Common Stock to credit the aggregate number of Exchange Shares to which each Purchaser is entitled pursuant to the Exchange to such Purchaser’s or its designee’s balance account with The Depository Trust Company through its Deposit/Withdrawal At Custodian system. For the avoidance of doubt, as of effectiveness of the Exchange, each Purchaser shall be deemed for all corporate purposes to have become the legal and record holder of its Exchange Shares without any further action by any party. In the event that any Exchange Shares are not delivered on a timely basis in accordance herewith, the Purchasers shall have the right to rescind and terminate any or all of this Agreement and the transactions contemplated hereby, to exercise any of the remedies available under the Notes in the event of any failure to timely deliver Conversion Shares (as if the Exchange Shares were Conversion Shares) and/or to exercise any and all other rights and remedies available at law or in equity.

(c)    Cancellation of Notes. Upon consummation of the Repayment and the Exchange (including delivery of all of the Exchange Shares to the Purchasers in accordance herewith), the Facility Agreement and all other Transaction Documents, including the Tranche 1 Notes, will have been repaid in full, will be deemed cancelled and will be of no further force or effect, as more fully set forth in (and subject to the terms and conditions of) the Payoff Letter and subject to Section 5.17.

Following the Exchange, the Purchasers will surrender the Tranche 1 Notes to the Borrower for cancellation.
