by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to the directors, officers, and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion
of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer, or controlling person of the Registrant in the successful defense of any action, suit or proceeding)
is asserted by such director, officer, or controlling person in connection with the securities being registered, the Registrant
will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will
be governed by final adjudication of such issue.</P>

<P STYLE="font-size: 10pt; text-align: justify; margin: 0pt 0">&nbsp;</P>

<P STYLE="font-size: 10pt; margin: 0pt 0">We have acted as counsel to Northern Technologies International Corporation, a Delaware
corporation (the &ldquo;Company&rdquo;), in connection with the Company&rsquo;s registration of an aggregate of 400,000 shares
(collectively, the &ldquo;Shares&rdquo;) of the Company&rsquo;s common stock, par value $0.02 per share (the &ldquo;Common Stock&rdquo;),
issuable under the Northern Technologies International Corporation 2019 Stock Incentive Plan (the &ldquo;Plan&rdquo;) pursuant
to a registration statement on Form S-8 (the &ldquo;Registration Statement&rdquo;) under the Securities Act of 1933, as amended
(the &ldquo;Securities Act&rdquo;), filed by the Company with the Securities and Exchange Commission (the &ldquo;SEC&rdquo;) on
January 28, 2019.</P>

certified or otherwise identified to our satisfaction, of such records, documents, certificates and other instruments as in our
judgment are necessary or appropriate to enable us to render the opinions expressed below. As to certain factual matters, we have
relied upon certificates of the officers of the Company and have not sought to independently verify such matters.</P>

<P STYLE="font-size: 10pt; margin: 0pt 0">&nbsp;</P>

such latter documents; the accuracy and completeness of all documents and records reviewed by us; the accuracy, completeness and
authenticity of certificates issued by any governmental official, office or agency and the absence of change in the information
contained therein from the effective date of any such certificate; and the due authorization, execution and delivery of all documents
where authorization, execution and delivery are prerequisites to the effectiveness of such documents.</P>

<P STYLE="font-size: 10pt; margin: 0pt 0">&nbsp;</P>

<P STYLE="font-size: 10pt; margin: 0pt 0">Our opinion herein is expressed solely with respect to the General Corporation Law of
the State of Delaware (including the statutory provisions, all applicable provisions of the Delaware Constitution and reported
judicial decisions interpreting the foregoing) and is based on these laws as in effect on the date hereof. We express no opinion
