Los Angeles, California

March 27, 2017

WHEREAS, on March 13, 2017, Sigma Labs, Inc., a Nevada corporation (the “Holder”) loaned to Morf3D, Inc., an Illinois corporation (the “Company”), $150,000 (the “Original Loan”) pursuant to a Secured Promissory Note (the “Original Note”);

WHEREAS, the Original Loan was made in contemplation of a possible transaction or transactions in which the Holder would make an additional loan to the Company and, thereafter possibly acquire or merge with the Company (a “Possible Combination”);

WHEREAS, the Holder is now willing to loan an additional $350,000 (the “Additional Loan”) to the Company and the Company is willing to accept this additional loan, in contemplation of the Possible Combination; and

WHEREAS, the Holder and the Company agree that the Original Note is hereby cancelled, of no further force and effect, and a copy of the Original Note shall be returned to the Company marked “cancelled”, and that the outstanding principal amount of the Original Loan, all unpaid interest and other amounts due, along with the Additional Loan are hereby represented by this Secured Convertible Promissory Note (this “Note”) in the aggregate principal amount of $500,000.00.

1.

Principal and Interest. The Company, for value received, hereby promises to pay to the order of the Holder in lawful money of the United States, the principal amount of Five Hundred Thousand and no/100 Dollars ($500,000.00) (the “Loan”), together with interest accrued on the unpaid principal of this Note at the rate of seven percent (7.0%) per annum commencing on the date of disbursement of the Loan. Subject to the conversion provisions of this Note, accrued interest on this Note shall be payable on the Maturity Date or the Payment Date (as such terms are defined below), as applicable. The Company agrees to use the principal amount of this Note only for leasing an EOS M 400 system, Company payroll and general working capital.

Subject to the conversion provisions of this Note, this Note is due and payable in full (a) on March 27, 2018 (the “Maturity Date”) or (b) on demand by written notice following an Event of Default (as defined below). The Company shall, on the Maturity Date or, if earlier, within one (1) business day of receipt of the written notice referred to in the immediately preceding sentence (the “Payment Date”), pay the outstanding principal and all accrued and unpaid interest on this Note as of the Maturity Date or the Payment Date, as applicable.

The Holder acknowledges and agrees that the provisions of this Note are not contingent on the occurrence of a Possible Combination, and that, absent an Event of Default, the Holder has no right to accelerate this Note prior to the Maturity Date or the Payment Date based solely on the failure of a Possible Combination to be consummated.

2.

Prepayment. The Company may not prepay this Note (in whole or in part) within ninety (90) days following the date hereof without the prior written consent of the Holder, which may be withheld or granted in the Holder’s sole discretion; provided, however, that, after such ninety (90) day period, the Company may prepay this Note (in whole or in part) without the prior written consent of the Holder.

3.

No Usury. This Note is hereby expressly limited so that in no event whatsoever, whether by reason of deferment or advancement of Loan proceeds, acceleration of maturity of the Loan evidenced hereby, or otherwise, shall the amount paid or agreed to be paid to the Holder hereunder for the loan, use, forbearance or detention of money exceed the maximum interest rate permitted by the laws of the State of Nevada. If at any time the performance of any provision involves a payment exceeding the limit of the price that may be validly charged for the Loan, or the use, forbearance or detention of money under applicable law, then automatically and retroactively, ipso facto, the obligation to be performed shall be reduced to such limit, it being the specific intent of the Company and the Holder hereof that all payments under this Note are to be credited first to interest as permitted by law, but not in excess of (a) the agreed rate of interest hereunder, or (b) that permitted by law, whichever is the lesser, and the balance toward the reduction of principal.

4.

Attorneys’ Fees. If the indebtedness represented by this Note or any part thereof is collected in bankruptcy, receivership or other judicial proceedings or if this Note is placed in the hands of attorneys for collection after the occurrence of an Event of Default, the Company agrees to pay, in addition to the principal and interest payable hereunder, reasonable attorneys’ fees and actual costs incurred by the Holder, as well as any and all interest that has accrued on the outstanding principal balance of this Note after the commencement of bankruptcy, receivership or other judicial proceedings.

5.

Transfer. The rights and obligations of the Company and the Holder of this Note will be binding upon and inure to the benefit of the successors, assigns, heirs, administrators and transferees of the parties hereto. Notwithstanding anything to the contrary herein, this Note is not transferrable by the Company without the prior written consent of the Holder, which consent may be withheld, delayed or conditioned in the Holder’s sole discretion.

6.

Notices. All notices, requests or other communications required or permitted to be delivered hereunder shall be delivered in writing to such address as the Company or the Holder, as applicable, may from time to time specify in writing. Notices if (a) mailed by certified or registered mail or sent by hand or overnight courier service shall be deemed to have been given when received, (b) sent by facsimile during the recipient’s normal business hours shall be deemed to have been given when sent (and if sent after normal business hours shall be deemed to have been given at the opening of the recipient’s business on the next business day) and (iii) sent by e-mail shall be deemed received upon the sender’s receipt of an acknowledgment from the intended recipient (such as by the “return receipt requested” function, as available, return e-mail or other written acknowledgment).

Security.

(a)

To secure all of its obligations hereunder, the Company hereby collaterally assigns, pledges and grants to the Holder a security interest in all of the Company’s right, title and interest in and to all of the Company’s tangible and intangible assets and property of any kind, no matter where now or hereafter located or existing and whether such assets and property, including cash, are now owned or hereafter acquired or created, all accessions, additions, improvements, replacements and substitutions thereto, all books, records and software related thereto (whether computer-stored or otherwise), and any and all proceeds or products of (or additions or accessories to) any of the foregoing (the “Collateral”); provided, however, that the Collateral shall not include equipment leased by the Company or acquired by the Company with purchase money indebtedness, whether or not the subject of UCC-1 financing statements as of the date hereof. The Company will, from time to time, execute, deliver, file and record, as applicable, any statement, assignment, instrument, document, agreement or other paper and take any other action that from time to time may be necessary in order to create, preserve, perfect, confirm, validate, or protect the foregoing security interest.

When all amounts due under this Note have been paid in full and/or converted per Section 11 of this Note, all of the provisions of this Note relating to the Collateral and the Holder ‘s secured interest therein shall terminate, and the Holder, at the request of the Company, will execute and deliver to the Company the proper instruments (including UCC termination statements) acknowledging the termination of such provisions, and will duly assign, transfer and deliver to the Company the Collateral. Until all amounts due under this Note have been paid in full, the Company shall not transfer, assign, pledge or hypothecate any of the Collateral, whether by operation of law or otherwise, other than in the ordinary course of business.

(b)

The Company represents and warrants to the Holder that, except for equipment leased by the Company or equipment acquired with purchase money indebtedness (whether or not the subject of UCC-1 financing statements) listed on Exhibit A hereto (the “Permitted Liens”), it owns good and marketable title to the Collateral, free and clear of any liens or encumbrances and that it has the full legal authority and power to grant the foregoing security interest in, and to assign, the Collateral to the Holder in the manner provided herein.
