FOR VALUE RECEIVED, the undersigned, iSign Solutions Inc., a Delaware corporation (the “Company”), hereby promises to pay to the order of __________________________________________ or its permitted assigns (the “Holder”) the principal sum of ______________________________ DOLLARS ($_____________), plus interest on the unpaid balance from the date hereof, at the rate of 10.0% per annum on the unpaid principal amount (or, if lower, the maximum interest rate permitted by applicable Law in accordance with Section 5), in lawful money of the United States of America or as otherwise provided in Section 1, at ___________________________________________________, or at such other place as the Holder may designate in writing. This Note (the “Note”) has been issued pursuant to the Note Purchase Agreement dated as of May __, 2017, as amended from time to time, among the Company and the Purchasers named therein (the “Purchase Agreement”) and is entitled to the benefits and rights provided therein. The obligations of the Company under this Note are secured as provided in the Purchase Agreement and that certain Security Agreement between the Company and SG Phoenix LLC, as collateral agent for the benefit of the Purchasers. Terms not otherwise defined herein shall have the definitions ascribed to them in the Purchase Agreement.

1.             Maturity Date; Interest Rate.

1.1          The principal of this Note, together with all unpaid interest and any other fees or expenses otherwise due and owed to the Holder under the Purchase Agreement, shall be due and payable on December 31, 2018 (the “Maturity Date”).

1.2           This Note shall bear interest at the rate of 10.0% per annum (or, if lower, the maximum interest rate permitted by applicable Law in accordance with Section 5) from the date hereof until repayment of the Note or conversion by the Holder of the Note in accordance with Section 3. Interest on this Note shall be computed on the basis of a three hundred sixty-five (365) day year and actual days elapsed. Furthermore, should this Note remain outstanding following the Maturity Date an additional 30% of this Note’s principal amount shall become due and payable.

1.3           Upon payment or conversion of all unpaid principal and accrued interest hereunder into the shares of Common Stock of the Company pursuant to Section 3, this Note shall be terminated in its entirety and shall be deemed surrendered to the Company for cancellation.

2.            Prepayment. This Note may be prepaid by the Company, in whole or in part, at any time prior to the Maturity Date, without penalty, by giving no less than fifteen (15) days’ prior notice to the Purchaser.

3.            Conversion.

3.1          Optional Conversion - Financing. In the event the Company consummates an equity or equity linked financing transaction through the sale and issuance of any new securities which provides gross cash proceeds to the Company in excess of One Million Dollars ($1,000,000) (a“ Financing”) during the term that this Note is outstanding, the Holder may elect to convert all (but not less than all) of the outstanding principal and accrued and unpaid interest hereunder into unregistered shares of Common Stock of the Company at the closing of the Financing in accordance with the conversion ratio set forth in Section 3.2 and the conversion procedures of Section 3.4. Upon conversion, this Note shall be cancelled.

3.2          Shares Issuable in Optional Conversion - Financing. The number of whole shares of Common Stock into which outstanding principal and accrued and unpaid interest under this Note shall be converted pursuant to Section 3.1 shall be determined by dividing (a) the aggregate principal amount of this Note, together with all accrued and unpaid interest through the date of conversion, by (b) the lesser of $0.50 or the price per share of Common Stock in the Financing. By way of illustration, (a) if the Company sold convertible notes or convertible preferred stock in the Financing and the conversion price of the convertible notes or convertible preferred stock was $0.25, then the Holder would be entitled to convert the outstanding principal and accrued and unpaid interest under this Note into shares of Common Stock at $0.25 (as opposed to $0.50) and (b) if the Company sold shares of the Common Stock at $1.00 per share and warrants to purchase shares of Common Stock at an exercise price of $1.25 in the Financing, then the Holder would be entitled to convert the outstanding principal and accrued and unpaid interest under this Note into shares of Common Stock at $0.50 (as opposed to $1.00).

3.3          Optional Conversion - Other . Except as provided in Section 3.1, the Holder may elect to convert all (but not less than all) of the outstanding principal and accrued and unpaid interest under this Note into unregistered whole shares of Common Stock of the Company determined by dividing (a) the aggregate principal amount of this Note, together with accrued and unpaid interest through the date of conversion, by (b) $0.50 and in accordance with Section 3.4. Upon conversion, this Note shall be cancelled.

3.4          Conversion Procedures.

(a)           The Company shall provide the Holder with written notice of a Financing no less than fifteen (15) days prior to the consummation of such Financing. If the Holder elects to convert this Note under Section 3.1, then within five (5) days of receipt of such notice the Holder shall deliver written notice to the Company, at the address of the Company’s principal executive office, of the Holder’s election to convert the outstanding principal amount of this Note and accrued interest to the date of such conversion into shares of Common Stock in accordance with Section 3.1.

(b)           If the Holder elects to convert this Note under Section 3.3, then the Holder shall deliver written notice to the Company of at least ten (10) days prior to the conversion date, at the address of the Company’s principal executive office, of the Holder’s election to convert the outstanding principal amount of this Note and accrued interest to the date of such conversion into shares of Common Stock in accordance with Section 3.3. In connection with giving either of such notice, the Holder shall surrender this Note to the Company for cancellation, as provided in Section 1.3.

3.5          Delivery of Book-Entry Shares. Upon the conversion of this Note into shares of Common Stock in accordance with the terms herein (and the return of the original Note to the Company together with executed copies of such ancillary agreements or documents executed by Holder as shall be reasonably requested by the Company), the Company at its expense will issue and deliver to the Holder of this Note book-entry shares (bearing such legends as are required by applicable federal and state securities laws in the opinion of counsel to the Company) for the number of whole shares of Common Stock issuable upon such conversion in accordance with Section 3.

3.6          No Fractional Shares. No fractional shares of Common Stock shall be issued upon conversion of this Note. In lieu of the Company issuing any fractional shares to the Holder upon the conversion of this Note, the Company shall pay to the Holder in cash the value of such fractional shares based upon the current market price of the Common Stock, as determined by the Company’s Board using the closing price of the Common Stock for the ten (10) consecutive trading days prior to the conversion date.
