Attention: Mr. Greg Fenton, Chief Executive Officer

Dear Sirs:

Based on the terms and conditions set out below, Eight Capital ("Eight"), as lead underwriter and sole bookrunner, and Leede Jones Gable Inc. and Research Capital Corporation (together with Eight, the "Underwriters" and each, an "Underwriter") hereby severally (and not jointly or jointly and severally), in their respective percentages set out in Section 16(a) below, offer to purchase for resale from Zentek Ltd. (the "Corporation"), and the Corporation, by its acceptance of this offer agrees to issue and sell to the Underwriters, at the Closing Time (as defined below), on a "bought deal" basis, an aggregate of 3,419,000 common shares of the Corporation (the "Initial Shares") of the Corporation at a purchase price of $5.85 per Initial Share (the "Offering Price") for aggregate gross proceeds to the Corporation of $20,001,150.

The Corporation hereby grants to the Underwriters an option (the "Over-Allotment Option") to purchase severally, and not jointly, nor jointly and severally, in their respective percentages set out in Section 16(a) below, up to an additional 512,850 Offered Shares of the Corporation (the "Over- Allotment Shares" and together with the Initial Shares, the "Offered Shares") at the Offering Price for additional gross proceeds of up to $3,000,172.50, upon the terms and conditions set forth herein for the purpose of covering over-allotments made in connection with the Offering (as hereinafter defined) and for market stabilization purposes. The Over-Allotment Option shall be exercisable, in whole or in part, and from time to time, by Eight, on behalf of the Underwriters, by giving written notice to the Corporation on or before a date that is not later than 30 days following the Closing Date (as hereinafter defined) and shall be exercisable to acquire Over-Allotment Shares at the Offering Price. Any such election to purchase the Over-Allotment Shares may be exercised only by written notice from Eight, on behalf of the Underwriters, to the Corporation by 8:00 a.m. (EST) on or before the 30th day following the Closing Date, such notice to set forth: (i) the aggregate number of Over-Allotment Shares to be purchased; and (ii) the Closing Date for the purchase of such shares, provided that such date shall not be less than two Business Days (as hereinafter defined) and no more than five Business Days following the date of such notice. The Initial Shares and the Over-Allotment Shares are collectively referred to herein as the "Offered Shares" and the offering of the Offered Shares by the Corporation is hereinafter referred to as the "Offering".

The Offered Shares may be distributed in each of the provinces of Canada other than the Province of Québec (the "Qualifying Jurisdictions") by the Underwriters pursuant to the Prospectus (as hereinafter defined) and may be offered and sold in the United States (as defined below) only in accordance with the U.S. Private Placement Memorandum (as defined below) and Schedule A hereto, which is incorporated by reference herein and forms part of this Agreement. In particular, all offers of the Offered Shares in the United States shall be made through a U.S. Affiliate (as defined in Schedule A hereto) of an Underwriter in accordance with all applicable U.S. Securities Laws (as defined below) and Schedule A hereto and all sales of the Offered Shares shall: (i) if made pursuant to Rule 506(b) of Regulation D (as defined in Schedule A hereto) be made directly by the Corporation to Substituted Purchasers (as hereinafter defined), or (ii) if made pursuant to Rule 144A (as defined in Schedule Ahereto), shall first be purchased by an Underwriter or a U.S. Affiliate, acting as principal, shall be resold in accordance with Rule 144A. Although this Agreement is presented on behalf of the Underwriters as purchasers, the Underwriters may arrange for substituted purchasers (the "Substituted Purchasers") for the Offered Shares in connection with private placements of such securities to Accredited Investors (as defined in Schedule A hereto) in accordance with Rule 506(b) of Regulation D. Each Substituted Purchaser shall purchase Offered Shares directly from the Corporation at the Offering Price, and to the extent that Substituted Purchasers purchase Offered Shares, the obligations of the Underwriters to do so will be reduced by the number of Offered Shares purchased by the Substituted Purchasers directly from the Corporation. Any reference in this Agreement hereafter to "purchasers" shall be taken to be a reference to the Underwriters, as the initial committed purchasers, and to the Substituted Purchasers, if any. Subject to applicable Laws, including the U.S. Securities Act (as defined in Schedule A hereto) and the terms of this Agreement, the Offered Shares may also be distributed outside of Canada and the United States where they may be lawfully sold on a basis exempt from the prospectus, registration and similar requirements of any such jurisdictions, provided that the Corporation is provided notice of and consents to such sales and that no prospectus filing or comparable obligation arises and the Corporation does not thereafter become subject to continuous disclosure obligations in such jurisdictions. For certainty, all offers and sales of Offered Shares shall be made in accordance with this Agreement, including Schedule A hereto.

2

In consideration of the agreement of the Underwriters to purchase the Offered Shares and to offer them to the public pursuant to the Prospectus, the Corporation agrees to pay to the Underwriters, at the Closing Time (as hereinafter defined), a fee equal to 6.0% of the Offering Price per Offered Share, or $0.351 per Offered Share, in respect of all Offered Shares to be sold to the Underwriters pursuant to the Offering (the "Underwriting Fee"). The obligation of the Corporation to pay the Underwriting Fee shall arise at the Closing Time and the Underwriting Fee shall be fully earned by the Underwriters at that time. The Corporation shall be entitled to designate in writing a list of purchaser's (the "President's List") who may purchase Offered Shares under the Offering. The Underwriters may, in their sole discretion, refuse to process any subscription for an investor on the President's List.

The Underwriters shall be entitled (but not obligated) in connection with the Offering to retain as sub-agents other registered securities dealers and may receive subscriptions for Offered Shares from subscribers from other registered dealers, at no additional cost to the Corporation. The fee payable to any such Selling Firm (as hereinafter defined) shall be for the account of the Underwriters.

The Underwriters may offer the Offered Shares at a price less than the Offering Price as described in further detail in Section 16(e) below, in compliance with Canadian Securities Laws (as hereinafter defined) and the disclosure concerning the same contained in the Offering Documents (as hereinafter defined).

In addition to the Offering, the Underwriters understand that the Corporation will offer and sell pursuant to the Prospectus, 1,710,944 Common Shares (as hereinafter defined) at a price of $5.85 per Common Share (the "Concurrent Non-Brokered Placement") concurrent with the closing of the Offering. The Underwriters undertake no obligation to the Corporation or to any purchaser under the Concurrent Non-Brokered Placement. The Corporation acknowledges and agrees that any purchaser under the Concurrent Non-Brokered Placement does not and will not have any recourse to or any rights against the Underwriters, and the Underwriters do not and will not have any liability whatsoever to any purchaser under or in connection with the Concurrent Non-Brokered Placement. No commission or other fee will be paid to the Underwriters in connection with the Concurrent Non-Brokered Placement.

(a)The purchase and sale of the Over-Allotment Shares, if required, shall be completed at such time and place as the Underwriters and the Corporation may agree, but in no event shall such closing occur later than five Business Days after written notice to purchase Over-Allotment Shares under the Over-Allotment Option is given in the manner contemplated herein.

(i)any breach of or default under any representation, warranty, covenant or agreement of the Corporation in this Agreement or the failure of the Corporation to comply with any of its obligations hereunder;

(ii)any information or statement (except any information or statement relating solely to an Indemnified Party and provided in writing by the Indemnified Party for inclusion in such document) contained in any of the Offering Documents or any other document or material filed or delivered by or on behalf of the Corporation pursuant to this Agreement being or being alleged to be a misrepresentation or untrue or any omission or alleged omission to state in those documents any material fact required to be stated in those documents or necessary to make any of the statements therein not misleading in light of the circumstances in which they were made;

(iii)any order made or any inquiry, investigation or proceeding instituted, threatened or announced by any court, securities regulatory authority, stock exchange or by any other competent authority, based upon any untrue statement, omission or misrepresentation or alleged untrue statement, omission or misrepresentation (except a statement, omission or misrepresentation relating solely to an Indemnified Party provided in writing by the Indemnified Party) contained in any of the Offering Documents or any other document or material filed or delivered by or on behalf of the Corporation pursuant to this Agreement, preventing or restricting the trading in or the sale or distribution of the Common Shares;

32

(iv)the Corporation not complying with any requirement of the Canadian Securities Laws or

U.S. Securities Laws, including the Corporation's non-compliance with any statutory requirement to make any document available for inspection; or

(v)any failure or alleged failure to make timely disclosure of a material change by the Corporation, where such failure or alleged failure occurs during the Offering or during the period of distribution or where such failure relates to the Offering or the Offered Shares and may give or gives rise to any liability under any Law in any jurisdiction which is in force on the date of this Agreement.

(b)The Underwriters shall not be required to conduct a suitability review in respect of sales to investors on the President's List and the Corporation shall indemnify and save harmless the Underwriters from any and all losses or expenses relating to sales to investors on the President's

List.

(c)The Corporation acknowledges and agrees that Underwriters do not and will not have any liability whatsoever to any purchaser under or in connection with the Concurrent Non-Brokered Placement and the Corporation shall indemnify and save harmless the Underwriters from any and all losses or expenses relating to sales to investors pursuant to the Concurrent Non-Brokered Placement.

(d)The Corporation agrees to waive any right they may have of first requiring an Indemnified Party to proceed against or enforce any other right, power, remedy or security or claim payment from any other person before claiming under this indemnity. The Corporation also agrees that no Indemnified Party shall have any liability (whether direct or indirect, in contract or tort or otherwise) to the Corporation or any person asserting Claims on behalf of or in right of the Corporation for or in connection with the Offering except to the extent any Losses suffered by the Corporation are determined by a court of competent jurisdiction in a final judgment that has become non-appealable to have resulted from the negligence or wilful misconduct of such Indemnified Party.

(e)The Corporation will not, without the Indemnified Party's prior written consent, settle, compromise, consent to the entry of any judgment in or otherwise seek to terminate any Claim in respect of which indemnification may be sought hereunder (whether or not any Indemnified Party is a party thereto) unless the Corporation has acknowledged in writing that the Indemnified Parties are entitled to be indemnified in respect of such Claim and such settlement, compromise, consent or termination includes an unconditional release of each Indemnified Party from any liabilities arising out of such Claim without any admission of negligence, misconduct, liability or responsibility by or on behalf of any Indemnified Party.

(f)Promptly after receiving notice of a Claim against an Indemnified Party or receipt of notice of the commencement of any investigation which is based, directly or indirectly, upon any matter in respect of which indemnification may be sought from the Corporation, the Indemnified Party will notify the Corporation in writing of the particulars thereof, provided that the omission so to notify the Corporation shall not relieve the Corporation of any liability which the Corporation may have to the Indemnified Party except and only to the extent that any such delay in or failure to give notice as herein required prejudices the defense of such Claim or results in any material increase in the liability which the Corporation has under this indemnity. The Corporation shall have 14 days after receipt of the notice to undertake, conduct and control, through counsel of its own choosing and at its own expense, the settlement or defense of the Claim. If the Corporation undertakes, conducts and controls the settlement or defense of the Claim, the relevant Indemnified Parties shall have the right to participate in the settlement or defense of the Claim, at the expense of the relevant Indemnified Party to the extent additional counsel or other external advisors are retained by such Indemnified Party.

33

(g)In any such Claim, such Indemnified Party shall have the right to retain separate legal counsel to act on such Indemnified Party's behalf, the reasonable fees and expenses of which counsel shall be at the expense of the Corporation if: (i) the Corporation does not assume the defence of the Claim within such 14 day period after receiving notice; (ii) the Corporation agrees to separate representation for the Indemnified Party, or (iii) the representation of the Corporation and such Indemnified Party by the same legal counsel would be inappropriate due to actual or potential differing interests, provided that in no circumstances will the Corporation be required to pay the reasonable fees and expenses of more than one legal counsel for all Indemnified Parties.

(h)Notwithstanding anything to the contrary contained herein, the foregoing indemnity shall cease to apply to the extent that a court of competent jurisdiction in a final judgment that has become non- appealable shall determine that such Losses to which the Indemnified Party may be subject were caused by the negligence, dishonesty, fraud or wilful misconduct of the Indemnified Party. For greater certainty, the Corporation and the Underwriters agree that they do not intend that any failure by the Underwriters to conduct such reasonable investigation as necessary to provide the Underwriters with reasonable grounds for believing the Offering Documents contained no misrepresentation shall constitute "negligence", "dishonesty", "fraud" or "willful misconduct" for the purposes of this Section 13 or otherwise disentitle the Underwriters from indemnification hereunder.

(i)The Corporation agrees that in case any legal proceeding shall be brought against the Corporation and/or the Underwriters by any governmental commission or regulatory authority or any stock exchange or other entity having regulatory authority, either domestic or foreign, shall investigate the Corporation and/or the Indemnified Parties shall be required to testify in connection therewith or shall be required to respond to procedures designed to discover information regarding, in connection with, or by reason of the performance of professional services rendered to the Corporation by the Underwriters, the Indemnified Parties shall have the right to employ their own counsel in connection therewith, and the reasonable fees and expenses of such counsel as well as the reasonable costs (including an amount to reimburse the Underwriters for time spent by the Indemnified Parties in connection therewith) and out-of-pocket expenses incurred by Indemnified Parties in connection therewith shall be paid by the Corporation as they occur.

(j)To the extent that any Indemnified Party is not a party to this Agreement, the Underwriters shall obtain and hold the right and benefit of the above-noted indemnity in trust for and on behalf of such Indemnified Party.

(k)The Corporation agrees to reimburse the Underwriters for the time spent by their personnel in connection with any Claim at their normal per diem rates.

34

(l)The indemnity and the contribution obligations of the Corporation pursuant to Section 14 shall be in addition to any liability which the Corporation may otherwise have, shall extend upon the same terms and conditions to the personnel of the Underwriters and shall be binding upon and enure to the benefit of any successors, assigns, heirs and personal representatives of the Corporation and any of the Indemnified Parties. The foregoing provisions shall survive the completion of professional services rendered under this Agreement or any termination of the authorization given by this Agreement.

Section 14Contribution

(a)In the event that the indemnity of the Corporation provided for in Section 13 hereof is declared by a court of competent jurisdiction to be illegal or unenforceable as being contrary to public policy or is unavailable for any other reason, the Underwriters and the Corporation shall severally, and not jointly, contribute to the aggregate of all Claims and all Losses of the nature contemplated in Section 13 hereof and suffered or incurred by the Indemnified Parties in proportions as is appropriate to reflect: (i) the relative benefits received by the Underwriters, on the one hand (being the Underwriting Fee), and the relative benefits received by the Corporation, as applicable, on the other hand (being the gross proceeds derived from the sale of the Offered Shares less the Underwriting Fee), (ii) the relative fault of the Corporation, on the one hand and the Underwriters on the other hand, and (iii) relevant equitable consideration; provided that the Corporation shall in any event contribute to the amount paid or payable by the Indemnified Parties as a result of such Claim any excess of such amount over the amount paid or payable to the Underwriters or any other Indemnified Party under this Agreement. For greater certainty and notwithstanding anything to the contrary contained herein, the Underwriters shall not in any event be liable to contribute, in the aggregate, any amount in excess of the Underwriting Fee or any portion thereof actually received. However, no party who has been determined by a court of competent jurisdiction in a final judgement to have engaged in any fraud, dishonesty, wilful misconduct or negligence shall be entitled to claim contribution from any person who has not been so determined to have engaged in such fraud, dishonesty, wilful misconduct or negligence.

(b)Any party entitled to contribution will, promptly after receiving notice of commencement of any claim, action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this section, notify such party or parties from whom contribution may be sought, but the omission to so notify such party shall not relieve the party from whom contribution may be sought from any obligation it may have otherwise under this section, except to the extent that the party from whom contribution may be sought is materially prejudiced by such omission. The right to contribution provided herein shall be in addition and not in derogation of any other right to contribution which the Underwriters may have by statute or otherwise by law.

Section 15Expenses

The Corporation will be responsible for all expenses related to the Offering, whether or not the Offering is completed, including, but not limited to, the fees and disbursements of the Corporation's legal counsel, the fees and disbursements of the Underwriters' legal counsel (up to an aggregate maximum of $125,000, exclusive of applicable taxes and disbursements), the fees and disbursements of accountants and auditors, the fees and disbursements of translators, the fees and disbursements of other applicable experts, the expenses related to road-shows and marketing activities, printing costs, filing fees, stock exchange fees, the reasonable out-of-pocket expenses of the Underwriters and taxes on all of the foregoing.

35

Section 16 Obligations of the Underwriters to be Several

(a)Subject to the terms and conditions of this Agreement, the obligation of the Underwriters to purchase the Offered Shares shall be several (and not joint or joint and several) and shall be as to the following percentages:

Eight Capital	70%
Leede Jones Gable Inc.	15%
Research Capital Corporation	15%
	100%

(b)If an Underwriter (a "Refusing Underwriter") fails to purchase its applicable percentage of the Offered Shares (each, "Defaulted Securities") which that Underwriter has agreed to purchase under this Agreement (other than in accordance with Section 12 hereof), the remaining Underwriter (the "Continuing Underwriter") shall have the right, but shall not be obligated, to purchase all but not less than all, of the Defaulted Securities. If the number of Defaulted Securities to be purchased by the Refusing Underwriter does not exceed 20% of the Offered Shares, the Continuing Underwriter will be obligated to purchase the Defaulted Securities on the terms set out in this Agreement; however, the Continuing Underwriters will not be required to purchase the Defaulted Securities if the Refusing Underwriter, or the Continuing Underwriter exercise or have exercised their termination rights pursuant to Section 11 hereof. Subject to the immediately preceding sentence, if the number of Defaulted Securities is greater than 20% of the Offered Shares, the Continuing Underwriter will not be obligated to purchase the Defaulted Securities and, if the Continuing Underwriter do not elect to purchase the Defaulted Securities:

(i)the Continuing Underwriter will not be obligated to purchase any of the Offered Shares;

(ii)the Corporation will not be obligated to sell less than all of the Offered Shares; and

(iii)the Corporation will be entitled to terminate its obligations under this Agreement, in which event there will be no further liability hereunder on the part of the Corporation or the Continuing Underwriters, except pursuant to the provisions of Section 13, Section 14 and Section 15.

(c)No action taken pursuant to this section shall relieve any Refusing Underwriter from responsibility in respect of its default to the Corporation or to any Continuing Underwriter.

(d)Nothing in this Agreement shall oblige any U.S. Affiliate of any of the Underwriters to purchase the Offered Shares. Any United States broker dealer who makes any offers or sales of the Offered Shares in the United States will do so solely as an agent for an Underwriter.

(e)Without affecting the obligation of the Underwriters to purchase the Initial Shares from the Corporation at the Offering Price in accordance with this Agreement, after the Underwriters have made reasonable effort to sell all of the Initial Shares at the Offering Price, the Offering Price may be decreased by the Underwriters and further changed from time to time to an amount not greater than the Offering Price specified herein. Such decrease in the Offering Price will decrease the Underwriting Fee ($0.351 per Offered Share) to be paid by the Corporation to the Underwriters, and it will not decrease the amount of the net proceeds of the Offering to be paid by the Underwriters to the Corporation ($5.499 per Offered Share), before deducting expenses of the Offering. The Underwriters will inform the Corporation if the Offering Price is decreased.

36

Section 17Action by Underwriters

All steps which must or may be taken by the Underwriters in connection with this Agreement resulting from the Corporation's acceptance of this offer, with the exception of the matters contemplated by Section 12, Section 13 and Section 14 may be taken by Eight on behalf of itself and the other Underwriter and the acceptance of this offer by the Corporation shall constitute the Corporation's authority for accepting notification of any such steps from, and for delivering the definitive documents in respect of the Offering to, or to the order of, Eight.

Section 18Governing Law

This Agreement shall be governed by and construed in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein. In the event of any dispute regarding the Agreement, the parties hereto submit to the non-exclusive jurisdiction of the courts of the Province of Ontario.

Except as expressly set out herein, all warranties, representations, covenants and agreements of the Corporation and the Underwriters herein contained or contained in documents submitted or required to be submitted pursuant to this Agreement shall survive the purchase by the Underwriters and shall continue in full force and effect for the benefit of the Underwriters or the Corporation, as the case may be, regardless of the Closing of the sale of the Offered Shares, any subsequent disposition of the Offered Shares by the Underwriters or the termination of the Underwriters' obligations under this Agreement for a period ending on the date that is two years following the Closing Date and shall not be limited or prejudiced by any investigation made by or on behalf of the Underwriters in accordance with the preparation of the Offering Documents or the distribution of the Offered Shares or otherwise, and the Corporation agrees that the Underwriters shall not be presumed to know of the existence of a claim against the Corporation under this Agreement or any certificate delivered pursuant to this Agreement or in connection with the purchase and sale of the Offered Shares as a result of any investigation made by or on behalf of the Underwriters in accordance with the preparation of the Offering Documents or the distribution of the Offered Shares or otherwise. Notwithstanding the foregoing, the provisions contained in this Agreement in any way related to indemnification or contribution obligations shall survive and continue in full force and effect, indefinitely.
