                                 PROXY STATEMENT
                       FOR ANNUAL MEETING OF STOCKHOLDERS

                                FEBRUARY 19, 1999

                                  INTRODUCTION

      The Annual Meeting of Stockholders of Northern Technologies International
Corporation (the "Company") will be held on Friday, February 19, 1999, at 11:00
a.m., local time, at the Hyatt Regency Minneapolis, 1300 Nicollet Mall,
Minneapolis, Minnesota 55403, or at any adjournments thereof (the "Annual
Meeting"), for the purposes set forth in the Notice of Meeting.

      A proxy card is enclosed for your use. You are solicited on behalf of the
Board of Directors to SIGN AND RETURN THE PROXY CARD IN THE ACCOMPANYING
ENVELOPE. No postage is required if mailed within the United States. The cost of
soliciting proxies, including the preparation, assembly and mailing of proxies
and soliciting material, as well as the cost of forwarding such material to the
beneficial owners of the Company's common stock, will be borne by the Company.
Directors, officers and regular employees of the Company may, without
compensation other than their regular compensation, solicit proxies by
telephone, telegraph or personal conversation. The Company may reimburse
brokerage firms and others for expenses in forwarding proxy materials to the
beneficial owners of the Company's common stock.

      Any stockholder giving a proxy may revoke it at any time prior to its use
at the Annual Meeting either by giving written notice of such revocation to the
Secretary of the Company, by filing a duly executed proxy bearing a later date
with the Secretary of the Company or by appearing at the Annual Meeting and
filing written notice of revocation with the Secretary of the Company prior to
use of the proxy. Proxies will be voted as specified by stockholders. Proxies
that are signed by stockholders but that lack any such specification will be
voted in favor of the proposals set forth in the Notice of Meeting and in favor
of the election as directors of the nominees for directors listed in this Proxy
Statement.

      THE BOARD RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE APPROVAL OF THE
PROPOSALS SET FORTH IN THE NOTICE OF MEETING.

      The Company expects that this proxy material will first be mailed to
stockholders on or about January 11, 1999.




                                VOTING OF SHARES

      Only holders of the Company's common stock, $.02 par value (the "Common
Stock"), of record at the close of business on December 30, 1998 will be
entitled to vote at the Annual Meeting. On December 30, 1998, the Company had
3,874,359 outstanding shares of Common Stock, each such share entitling the
holder thereof to one vote on each matter to be voted on at the Annual Meeting.
The holders of a majority of the shares entitled to vote and represented in
person or by proxy at the Annual Meeting will constitute a quorum for the
transaction of business at the Annual Meeting. In general, shares of Common
Stock represented by a properly signed and returned proxy card will be counted
as shares present and entitled to vote at the meeting for purposes of
determining a quorum, without regard to whether the card reflects abstentions
(or is left blank) or reflects a "broker non-vote" on a matter (i.e., a card
returned by a broker because voting instructions have not been received and the
broker has no discretionary authority to vote). Holders of shares of Common
Stock are not entitled to cumulate voting rights.

      The election of a nominee for director requires the approval of a
plurality of the votes of the shares present and entitled to vote in person or
by proxy and the approval of the other proposal described in this Proxy
Statement requires the approval of a majority of the votes of the shares present
and entitled to vote in person or by proxy on that matter (and at least a
majority of the minimum number of votes necessary for a quorum to transact
business at the Annual Meeting). Shares represented by a proxy card voted as
abstaining on any of the proposals will be treated as shares present and
entitled to vote that were not cast in favor of a particular matter, and thus
will be counted as votes against the matter. Shares represented by a proxy card
including any broker non-vote on a matter will be treated as shares not entitled
to vote on that matter, and thus will not be counted in determining whether that
matter has been approved.

                              ELECTION OF DIRECTORS

NOMINATION

      The Bylaws of the Company, as amended, provide that the Board of Directors
(the "Board") shall consist of eight members. The Board has nominated the eight
persons listed in this Proxy Statement to serve as directors of the Company
until the next regular meeting of stockholders or until their successors are
elected and qualified. All of the nominees are current members of the Board.

      Assuming a quorum is represented at the Annual Meeting, either in person
or by proxy, the election of each director requires the affirmative vote of a
plurality of the shares of Common Stock represented in person or by proxy at the
Annual Meeting. The Board recommends a vote FOR the election of each of the
nominees listed in this Proxy Statement. The Board intends to vote the proxies
solicited on its behalf for the election of each of the nominees as directors.
If prior to the Annual Meeting the Board should learn that any of the nominees
will be unable to serve by reason of death, incapacity or other unexpected
occurrence, the proxies may be cast for another nominee to be designated by the
Board to fill such vacancy, unless the stockholder indicates to the contrary on
the proxy. Alternatively, the proxies may, at the Board's discretion, be voted
for such fewer nominees as results from such death, incapacity or other
unexpected occurrence. The Board has no reason to believe that any of the
nominees will be unable to serve.


                                        2

On August 31, 1998, the fair market value of the Common Stock was $6.4375 per share. 9 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS On October 1, 1976, the Company entered into a Manufacturer's Representative Agreement with The Saxxon Organization, Incorporated (the "Agreement"). The Agreement has no expiration date and may be terminated by either party upon 60 days written notice. Effective January 9, 1980, the Agreement was assigned to Inter Alia Holding Company, a financial and management consulting firm of which Philip M. Lynch, the Chairman of the Board of Directors of the Company, is an officer and director. Under the Agreement, Inter Alia Holding Company (or the "Representative") is entitled to commissions from the Company on the net proceeds of sales of the Company's product generated by Inter Alia Holding Company. The Representative acts as an independent manufacturer's representative of the Company. It has a non-exclusive worldwide right to offer for sale and solicit orders for the Company's products in accordance with prices determined by the Company. The Representative is responsible for all of its own operating expenses with no entitlement for reimbursement from the Company. The Representative has not effected any sales within the United States. The Representative's effort has developed sales outside the United States, which resulted in commissions of $51,754, $42,582 and $52,950 for the fiscal years ending August 31, 1998, 1997 and 1996, respectively. In light of the Company's own domestic sales effort and its distributor network within the United States, the Company does not anticipate the Representative developing any sales within the United States. Additionally, the Company's expanding international joint venture program may also limit opportunities abroad for the Representative. Thus, the Company does not anticipate that the Representative will develop any significant sales volume for the Company. On August 31, 1984, Inter Alia purchased 119,083 shares of Common Stock and paid therefor by signing a promissory note. The promissory note (the "Note") has a face value of $125,375 and bears interest at 11% per year. The Note was originally due on December 31, 1992 and is currently due on demand. The outstanding balance of the Note, including accrued interest of $105,543 was $230,919 at August 31, 1998. Gerhard Hahn, a director of the Company, is a shareholder and General Manager of Knuppel KG. Knuppel KG is a 50% partner with the Company in a joint venture in Germany. The German joint venture entity has granted a loan of 750,000 DM to Knuppel KG. The loan is secured by Knuppel KG's equity in the German joint venture and bears interest at 7.5% per annum. Haruhiko Rikuta, a director of the Company, is Manager, Zerust Department of Taiyo Petroleum Gas Co. Ltd. ("Taiyo Petroleum"). Taiyo Petroleum is a 50% partner with the Company in Taiyonic Limited, the Company's joint venture in Japan.
