SECURITY AGREEMENT

This Security Agreement (the “Agreement”) is entered into as of this 17th day of
October, 2016 by and between Sigma Labs, Inc., a Nevada corporation (the
“Borrower”), and L1 Capital Global Opportunities Master Fund Ltd, in its
capacity as Collateral Agent (together with its successors and assigns in such
capacity, the “Secured Party”) for the benefit of itself and each of the
Purchasers, as defined in the Securities Purchase Agreement by and among the
Borrower and each of the Purchasers as of the date of this Agreement (the
“SPA”).

WHEREAS, the Purchasers have agreed to lend certain funds to the Borrower (the
"Loan"), and the Borrower desires to borrow such funds from the Purchasers.

WHEREAS, in order to induce the Purchasers to make the Loan, the Borrower has
agreed to grant a security interest in certain tangible and intangible property
to the Secured Party for purposes of securing the obligations of the Borrower to
the Purchasers.

NOW, THEREFORE, the parties hereto agree as follows:

1.

Creation of Security Interest. In connection with the issuance by the Borrower
of the Notes, as defined in the SPA, and as consideration for the Purchasers’
advance of funds thereunder, the Borrower hereby grants to the Secured Party a
security interest in the Collateral described in Section 2 to secure the
performance or payment of all of the obligations of the Borrower under Section
3.

2.

Collateral. The collateral of this Agreement (the “Collateral”) consists of the
items described on attached Exhibit A, including the Physical Collateral and the
Patent Collateral, as defined in Exhibit A. Notwithstanding anything to the
contrary herein, the obligations under Section 3(b) and Section 4 of this
Agreement will not be deemed to apply to cash that is part of the Collateral.

3.

The Borrower's Obligations.

(a)

Obligation to Pay. The Borrower shall pay to the Purchasers $1,000,000 and
accrued interest thereon in accordance with the terms of the Notes.

(b)

Additional Obligations.

(i)

Protection of Collateral. The Physical Collateral:

(1)

will not be misused or abused, but will be maintained in good and operable
condition, reasonable wear and tear excepted (except for any loss, damage or
destruction which is fully covered by insurance proceeds) and will be repaired,
renewed and replaced by the Borrower, in the exercise of reasonable discretion,
as the Borrower shall deem necessary;

(2)

will be insured by the Borrower in the amount of at least $1,000,000 until this
Agreement is terminated against all expected risks to which it is exposed,
including fire, theft, wind and flood, and those which the Secured Party may
reasonably designate, with the policies reasonably acceptable to the Secured
Party, and providing for 30 days' minimum cancellation notice to the Secured
Party, and with certificates evidencing such insurance delivered to the Secured
Party within ten days following the making of the Loans. The Borrower agrees to
apply any such insurance proceeds to the replacement or repair of any damaged
Collateral and, to the extent the Borrower does not do so within sixty days
after receiving such proceeds, the Borrower will apply the proceeds to the
Notes.

(ii)

Protection of Security Interest.

(1)

The Collateral will not be sold, licensed, transferred, encumbered, pledged, or
disposed of or be subjected to any unpaid charge, including taxes, or to any
subsequent interest of a third person created or suffered by the Borrower
voluntarily or involuntarily, unless the Secured Party consents in advance in
writing to such charge, transfer, disposition or subsequent interest, provided,
however, that the Collateral may be sold, leased or licensed to third parties in
the ordinary course of the Borrower's business, and

(2)

Upon the making of the Loan, the Secured Party will file a Financing Statement
with the Nevada Secretary of State and, upon notice to the Borrower, may file
additional Financing Statements it deems necessary in places it deems
appropriate to protect the security interest under this Agreement against the
rights or interests of third persons.

--------------------------------------------------------------------------------

(3)

Any proceeds received by the Borrower upon the sale, lease, license, assignment,
transfer, encumbrance, pledge or other disposition of any of the Collateral or
any part thereof shall be paid to the Secured Party when received and applied to
the Notes of the Purchasers on a pro rata basis (based on the amount of each
Loan) until all principal, accrued interest and attorneys’ fees outstanding
under the Notes are paid in full. All additional proceeds, if any, from such
sale or other disposition shall be retained by the Borrower. Notwithstanding
anything to the contrary in this Agreement, all proceeds from selling, leasing
and licensing the Collateral in the ordinary course of the Borrower's business
shall be retained by the Borrower.

4.

Representations, Warranties and Covenants. The Borrower represents, warrants and
covenants to the Secured Party that:

(i)

The Borrower has good and sufficient title to the Collateral that is material to
the business of the Company, free and clear of all security interests, liens,
encumbrances and claims whatsoever, other than those created in favor of the
Secured Party, and except for Liens (as defined in the SPA) permitted under the
SPA.

(ii)

To the knowledge of the Borrower, no financing statement, notice of lien,
security agreement or any other agreement or instrument creating or giving
notice of an encumbrance or charge against any of the Collateral is in existence
or on file in any public office, except those in favor of Secured Party.

(iii)

The Borrower will at all times hereafter keep the Collateral free of all
security interests, liens and claims whatsoever, except for the security
interests, liens and claims in favor of the Secured Party, and except for Liens
permitted under the SPA.

(iv)

The Borrower (i) will, from time to time, on the reasonable request of the
Secured Party, execute such financing statements, statements of assignment,
notices and other documents and pay the costs of filing or recording the same in
all public offices deemed necessary by the Secured Party and do such other
reasonable acts as the Secured Party may request to establish and maintain a
valid security interest in the Collateral at the Borrower’s expense and to file
any financing statements, or any notices or assignments with the Patent and
Trademark Office, relating to the Collateral (without the Borrower’s signature
thereon) which the Secured Party deems reasonably appropriate.

(v)

the Borrower irrevocably appoints the Secured Party as the Borrower’s
attorney-in-fact during the existence of an Event of Default (as defined in the
Notes) with full power of substitution, in its own name or in the Borrower’s
name, place and stead:

(1)

To file any financing statements, and any documents in the Patent and Trademark
Office that the Secured Party deems appropriate in connection with the
perfection, protection, priority or enforcement of the Secured Party’s security
interest in the Collateral;

(2)

To take any actions required of the Borrower under this Agreement that the
Borrower fails or is unable to take in a timely manner; and

(3)

While the Borrower is in default under this Agreement, to take any actions that
the Secured Party deems reasonably appropriate (i) to protect, preserve or
realize upon the Collateral and its security interest in the Collateral or to
accomplish the purposes of this Agreement, including any actions described in
Section 6 and (ii) in connection with the disposition of any Collateral (1) to
assign or transfer title to such Collateral to itself or to any third party
purchaser in connection with the Secured Party’s exercise of its rights under
the Uniform Commercial Code, and (2) to file with the Patent and Trademark
Office or other governmental office or authority any documents necessary or
advisable to implement, effectuate or reflect the disposition.

(4)

The Secured Party will not disturb the rights of any third-party licensee or
lessee of the Patent Collateral under a license or lease granted by the Borrower
in the ordinary course of business so long as the licensee or lessee, as
applicable, is not in breach of its obligations to the Borrower under the
license or lease.

Except where prior notice is expressly required by the terms of this Agreement,
the Secured Party shall use commercially reasonable efforts to provide notice to
the Borrower prior to taking any action taken under this Section 4(v), provided
that failure to deliver such notice shall not limit the Secured Party's right to
take such action or the validity of any such action.

(vi)

Except as otherwise provided herein, the Borrower will account fully and
faithfully for and promptly pay or turn over to the Secured Party proceeds in
whatever form received in disposition in any manner of any of the Collateral as
provided herein.

(vii)

All information now or hereafter furnished by the Borrower to the Secured Party
relating in any way to the Collateral, is and will be true and correct in all
material respects as of the date furnished.

--------------------------------------------------------------------------------

5.

Default. Any material misrepresentation or misstatement in connection with, or
non-compliance with or non-performance of the Notes or this Agreement, a breach
of the SPA or the occurrence of an event of default under the Notes, shall
constitute default under this Agreement, provided, however, that any such
non-compliance, non-performance or breach shall constitute default under this
Agreement if such non-compliance, non-performance or breach, as applicable,
continues for ten days after written notice to the Borrower. In addition, the
Borrower shall be in default if (i) bankruptcy or insolvency proceedings are
instituted by or against the Borrower, which proceedings are not dismissed
within 30 days; (ii) if the Borrower makes any assignment for the benefit of
creditors, or (iii) if the Borrower shall default in performance of any
agreement with the Purchasers, which default is not cured within ten days after
written notice to the Borrower.

6.

The Secured Party's Rights and Remedies.

(a)

The Secured Party may assign this Agreement, with notice to the Borrower, and,
if the Secured Party does assign this Agreement, the assignee shall be entitled,
upon notifying the Borrower, to performance of all of the Borrower's obligations
under this Agreement.

(b)

If any default hereunder by the Borrower shall have occurred and be continuing,
the Secured Party may exercise its rights of enforcement under the Uniform
Commercial Code in force in Nevada and any notice of lien filed with the United
States Patent Office and, in conjunction with, addition to or substitution for
those rights, at the Secured Party's discretion, it may:

(i)

To the extent permitted by law, enter upon the Borrower's premises for a
reasonable period to take possession of, assemble and collect the Collateral.

(ii)

Require the Borrower to assemble the Collateral and make it available at a place
the Secured Party designates which is mutually convenient, to allow the Secured
Party to take possession or sell, lease, license or otherwise dispose of the
Collateral.

(iii)

Waive any default or remedy any default in any reasonable manner without waiving
the default remedied and without waiving any other prior or subsequent default.

(iv)

the Borrower understands that to the extent permitted by law, if any default
hereunder by the Borrower shall have occurred and be continuing, the Secured
Party has a right to take possession of the Collateral by all lawful means and
to sell, lease, license or otherwise dispose of the Collateral.

(c)

Except as otherwise provided herein, with regards to only non-monetary defaults,
the Secured Party will give notice to the Borrower that the Borrower is in
default hereunder, and the Borrower shall have ten days from the date of such
notice to cure the non-monetary defaults.

(d)

The Secured Party’s remedies are limited to recovering its outstanding principal
and accrued interest under the Notes, attorneys’ fees and costs incurred in the
sale of the Collateral.

7.

Other Lienholders. Any person or entity taking a junior encumbrance, or other
lien upon the Collateral or any part thereof or any interest therein, shall take
said lien subject to the rights of the Secured Party as provided in the Notes to
amend, modify, extend, renew, enlarge or release the Notes, this Agreement (as
provided herein) or any other document or instrument evidencing, securing or
guaranteeing the Notes, including, but not limited to, any amendments,
modifications, extensions or renewals that increase the amount outstanding under
the Notes, in each and every case without obtaining the consent of the holder of
such junior lien and without the lien of this Agreement losing its priority over
the rights of any such junior lien. Accordingly, any person or entity taking a
junior encumbrance, or other lien upon the Collateral or any part therein or any
interest therein, shall take said lien subject to the provisions of the Notes
and this Agreement, including, but not limited to, the above provision. Nothing
in this Section shall be deemed to authorize any such junior encumbrance or
other liens on the Collateral.

 

8.

Severability. In the event any parts of this Agreement are found to be void, the
remaining provisions of this Agreement shall nevertheless be binding with the
same effect as though the void parts were deleted.

9.

Counterparts. This Agreement may be executed in one or more counterparts, each
of which shall be deemed an original but all of which together shall constitute
one and the same instrument. The execution of this Agreement may be by actual or
facsimile signature, or in electronic (i.e., “pdf” or "tif") format.
