Item 6.  Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

The Reporting Person was issued a total of 10,000,000 Preferred Shares effective December 31, 2006 pursuant to the TTA under which the Issuer acquired certain rights to utilize the SFD® technology for use in hydrocarbon exploration. The Preferred Shares are non-voting, are convertible into Common Shares on a 1-for-1 basis, and mature on December 31, 2015 (the “Maturity”).

4

A total of 2,000,000 of the Preferred Shares became immediately convertible upon issue in 2006, with the remaining balance of 8,000,000 contingently convertible before Maturity based upon the Issuer achieving certain milestones based on cumulative revenues.

Effective May 22, 2013, the Reporting Person exercised his right to convert the initial 2,000,000 of the Preferred Shares into 2,000,000 Common Shares, following which he held a total of 7,196,490 (or 17.3%) of the Issuer’s 41,554,959 then outstanding Common Shares.

The remaining 8,000,000 Preferred Shares were able to be converted before Maturity in four separate increments of 2,000,000 Preferred Shares each, if the Issuer achieved specified “Cumulative Revenue” thresholds of US$50 million, US$100 million, US$250 million and US$500 million. An additional 1,000,000 Common Shares were issuable to the Reporting Person in the event that Cumulative Revenues exceed US$500 million by December 31, 2015.

In the event that the final Cumulative Revenue threshold of US$500 million were not achieved by December 31, 2015, the Issuer had the option to either redeem any remaining unconverted Preferred Shares for a price of $0.001 per share and forfeit its rights to the SFD® technology, or elect to retain the ownership of the SFD® technology by converting all of the remaining Preferred Shares into Common Shares.

As of June 30, 2015, Cumulative Revenues earned by the Issuer were US$29.5 million.

The Board of Directors of the Issuer had the right to cause the conversion of the remaining outstanding Preferred Shares, and elected to do so effective August 31, 2015, to allow the Issuer to retain its rights to the SFD® technology.

Also, in January 2014, the Reporting Person personally granted (to a total of 17 persons, including Issuer employees, directors, officers, advisors and others) “Rights” to acquire a total of 1,000,000 Common Shares which are now being issued to him upon conversion of the 8,000,000 Preferred Shares. Each of these Rights were subject to certain vesting provisions and will entitle the holder to acquire from the Reporting Person one Common Shares at a fixed exercise price of Cdn $1.77 per share and will expire on December 31, 2015.  The form of “Performance Option Award” agreement related to these Rights is attached as Exhibit 2

C. Upon the satisfaction of the Revenue Threshold, or upon the Preferred Shares otherwise becoming convertible into Common Shares in accordance with the Preferred Share Provisions, (which includes a maturity date of the Preferred Shares of December 31, 2015), the Grantor intends to convert the Preferred Shares into Common Shares; and

D. The Grantor has agreed to grant options on the terms and conditions set forth herein to acquire the number of Common Shares provided for in this Agreement (the "Option Shares") to the Optionee in recognition of the Optionee's past services as an employee, executive officer, director, or consultantto NXT and as an incentive for the Optionee to continue to use the Optionee's best efforts to provide services to NXT and to promote its interests;

NOW THEREFORE, IN CONSIDERATION OF THE MUTUAL COVENANTS AND AGREEMENTS CONTAINED HEREIN, THE PARTIES AGREE AS FOLLOWS:

1.           The Grantor hereby grants to the Optionee, on the terms and conditions contained herein, an irrevocable right to purchase from the Grantor an aggregate of ___ Option Shares, being Common Shares that the Grantor will acquire upon the conversion of ___ of the Preferred Shares, upon the payment by the Optionee to the Grantor of the exercise price (the “Exercise Price”), exercisable within the periods of time set forth in Section 3 of this Agreement (the "Acquired Shares").  All of the Option Shares granted pursuant to this Agreement are designated as performance options (the "Performance Options").  The maximum Exercise

⁠

- 2 -

Price payable to acquire all of the Option Shares shall be $_________  (Cdn $1.77 per Option Share), being an amount which is equal, in the aggregate, to the designated value payable for the Acquired Shares.

2.           The Optionee’s entitlement to exercise the Performance Options will vest upon on the third business day following the satisfaction of the performance criteria (the "Performance Criteria") attached to this Agreement as Schedule “A”. The Grantor shall give notice to the Optionee upon the satisfaction of the Performance Criteria being met.

3.           Provided that the Optionee remains an employee or Officer of NXT, or a consultant to NXT, at the time of vesting, at any time after a Performance Option has become vested in accordance with Section 2, the Optionee may exercise the Performance Option before 5:00 p.m. (Calgary time) on December 31, 2015 (the "Expiry Date").   At 5:00 p.m. (Calgary time) on the Expiry Date, the Performance Option terminates and is of no further force or effect in respect of those Option Shares for which the Performance Option has not been exercised. For greater certainty this paragraph 3 shall not apply to the Board of Directors.

4.           In the event of the death of the Optionee, all Performance Options that have vested in accordance with Section 2 on or prior to the Optionee's death shall be exercisable by the legal representative of the Optionee until 5:00 p.m. (Calgary time) on the day that is the earlier of 60 days after the death of the Optionee and the Expiry Date.  All Performance Options that have not yet vested on or prior to the Optionee's death shall terminate and be of no further force and effect.

6.           The Optionee acknowledges and agrees that the Optionee is responsible for all income taxes arising from grant, holding, exercise, or disposition of the Performance Options and the receipt of the Acquired Shares.

7.           Nothing contained in this Agreement requires the Optionee to purchase any Option Shares except those Option Shares in respect of which the Optionee has exercised Performance Options in the manner provided in Section 5 of this Agreement.

8.           The Optionee shall have no rights as a shareholder with respect to any of the Option Shares, including without limitation, the right to receive dividends or other distributions thereon, and the right to vote the Option Shares at any shareholders meeting or sign any resolution in writing, other than in respect of those Option Shares for which the Optionee has validly exercised Performance Options and for which Acquired Shares have been issued.

9.           Any question, conflicts or disputes arising under this Agreement as to the interpretation, construction or enforcement of the Performance Option are to be determined by the Grantor in his sole discretion and the Optionee agrees that the Grantor's decision is final and binding on the parties.

10.           In the event that the basis upon which the Preferred Shares may be converted into Common Shares is adjusted pursuant to Section 5 of the Preferred Share Provisions, then upon any exercise thereafter of the Performance Options, the Optionee shall receive, upon due payment of the Exercise Price, in lieu of each Acquired Share that the Optionee would have received prior to the adjustment contemplated hereby, that number of Acquired Shares (which may be a fraction) received by the Grantor from NXT upon the conversion of each one Preferred Share.

12.           In the event that the Preferred Shares become convertible into common shares of NXT pursuant to Section 4.1(b) (but for greater certainty, not including 4.1(a)) of the Preferred Share Provisions, then the Revenue Threshold shall be deemed to be fulfilled for the purposes of Section 2 hereof.

13.           In the event that there is or has been a change of control of NXT (as defined in Schedule A) after the entering into of this Agreement, then all rights under this Agreement as may be applicable to the Optionee, shall immediately vest for the benefit of the Optionee.
