SUPPLEMENTAL WARRANT INDENTURE

Dated as of December 13, 2018

            THIS SUPPLEMENTAL WARRANT INDENTURE (the “Supplemental Indenture”) is made as of the 13th day of December, 2018.

BETWEEN:

            PLATINUM GROUP METALS LTD., a corporation existing under the laws of the Province of British Columbia (the “Corporation”)

            - and -

            COMPUTERSHARE TRUST COMPANY OF CANADA, a trust company existing under the laws of Canada and authorized to carry on business in all provinces of Canada (the “Warrant Agent”)

WHEREAS:

A.        The Corporation and Warrant Agent entered into a common share purchase warrant indenture dated May 15, 2018 (the “Warrant Indenture”) providing for the issuance of up to 131,100,000 common share purchase warrants (the “Warrants”) and pursuant to which the Warrant Agent holds all rights, interests and benefits contained therein for and on behalf of those persons who from time to time become holders of Warrants issued pursuant to the Warrant Indenture;

B.        Effective as of 9:00 a.m. (New York time) on December 13, 2018 (the “Effective Date”), the outstanding common shares of the Corporation (the “Common Shares”) were consolidated on a ten (10) old Common Shares for one (1) new Common Share basis. As a result, in accordance with the provisions of Article 4 of the Warrant Indenture, the exercise price of the Warrants is increased from US$0.17 to US$1.70 (US$0.17 x 10) (the “Exercise Price”) and the exchange rate is adjusted to 0.10 (1 x 0.17/1.70) (the “Exchange Rate”). Therefore, the Corporation has determined to amend the Warrant Indenture to reflect the adjustment of the Exercise Price and Exchange Rate of the Warrants issuable under the Warrant Indenture;

C.        Section 8.1 of the Warrant Indenture provides that the Corporation and the Warrant Agent may execute and deliver an indenture supplemental to the Warrant Indenture setting forth any adjustments resulting from the application of Article 4 of the Warrant Indenture; and

D.        Recital B is made as representations and statements of fact by the Corporation and not by the Warrant Agent.

NOW THEREFORE, the parties hereto agree as follows:

Amendment to Warrant Indenture

1.	The Warrant Indenture is hereby amended as follows:
	a.	deleting the definition of “Exercise Price” in section 1.1 and replacing it with the following:
		“Exercise Price” at any time means the price at which a whole Common Share may be purchased by the exercise of Warrants, which is initially US$1.70 per Common Share, payable in immediately available United States funds, subject to adjustment in accordance with the provisions of this Indenture;
	b.	deleting section 2.2(1) and replacing it with the following:

(1) Subject to the applicable conditions for exercise set out in Article 3 having been satisfied and subject to adjustment in accordance herewith, each ten (10) Warrants shall entitle each Warrantholder thereof, upon exercise at any time after the Issue Date and prior to the Expiry Time, to acquire one (1) Common Share upon payment of the Exercise Price;

c. deleting section 3.1 and replacing it with the following:

            Subject to the provisions hereof, each Registered Warrantholder may exercise the right conferred on such holder to subscribe for and purchase one (1) Common Share for each ten (10) Warrants after the Issue Date and prior to the Expiry Time and in accordance with the conditions herein.

d. deleting Schedule “A” and Schedule “B” and replacing it with Schedule “A” and Schedule “B” attached hereto.

Effect of Amendments

2.        The Warrants issued and outstanding shall be deemed to include the amendments as set forth herein, without any further action of the Registered Warrantholders or surrender or exchange of their warrant certificates.

3.        The parties confirm that the Warrant Indenture, as amended by this Supplemental Indenture, remains in full force and effect. From the date hereof, the Warrant Indenture and this Supplemental Indenture shall be read together to the extent reasonably possible as though all of the terms of both documents were contained in one instrument.

- 3 -

Counterparts and Formal Date

4.        This Supplemental Indenture may be executed in several counterparts, each of which when so executed shall be deemed to be an original and such counterparts together shall constitute one and the same instrument and notwithstanding their date of execution they shall be deemed to be dated as of the date hereof.

Capitalized Terms

5.        Capitalized terms that are used herein shall, unless otherwise defined herein, have the meanings ascribed thereto in the Warrant Indenture.

IN WITNESS WHEREOF the parties hereto have executed this Supplemental Indenture as of the date first written above.

SCHEDULE “A”

FORM OF WARRANT

WARRANT

To acquire Common Shares of
PLATINUM GROUP METALS LTD.

(existing pursuant to the laws of the Province of British Columbia)

Warrant	Certificate for ___________________________
Certificate No. __________	Warrants, each ten (10) Warrants entitling the
	holder to acquire one (1) Common Share
	(subject to adjustment as provided for in the
	Warrant Indenture (as defined below)
	CUSIP 72765Q155 / ISIN CA72765Q1550

THIS IS TO CERTIFY THAT, for value received,

___________________________________________________________________________________________________
(the “Warrantholder”) is the registered holder of the number of common share purchase warrants (the “Warrants”) of Platinum Group Metals Ltd. (the “Corporation”) specified above, and is entitled, on exercise of these Warrants upon and subject to the terms and conditions set forth herein and in the Warrant Indenture, to purchase at any time before 4:00 p.m. (Vancouver time) (the “Expiry Time”) on November 15, 2019 (the “Expiry Date”), for each ten (10) Warrants one (1) fully paid and non-assessable common share without par value in the capital of the Corporation as constituted on the date hereof (a “Common Share”) for each Warrant subject to adjustment in accordance with the terms of the Warrant Indenture.

The right to purchase Common Shares may only be exercised by the Warrantholder within the time set forth above by:

(a)

duly completing and executing the exercise form (the “Exercise Form”) attached hereto; and

(b)

surrendering this warrant certificate (the “Warrant Certificate”), with the Exercise Form to the Warrant Agent at the principal office of the Warrant Agent, in the city of Vancouver, together with a certified cheque, bank draft or money order in the lawful money of the United States of America payable to or to the order of the Corporation in an amount equal to the purchase price of the Common Shares so subscribed for.

The surrender of this Warrant Certificate, the duly completed Exercise Form and payment as provided above will be deemed to have been effected only on personal delivery thereof to, or if sent by mail or other means of transmission on actual receipt thereof by, the Warrant Agent at its principal office as set out above.

A-2

Subject to adjustment thereof in the events and in the manner set forth in the Warrant Indenture hereinafter referred to, the exercise price payable for each Common Share upon the exercise of Warrants shall be US$1.70 per Common Share (the “Exercise Price”).

Certificates for the Common Shares subscribed for will be mailed to the persons specified in the Exercise Form at their respective addresses specified therein or, if so specified in the Exercise Form, delivered to such persons at the office where this Warrant Certificate is surrendered. If fewer Common Shares are purchased than the number that can be purchased pursuant to this Warrant Certificate, the holder hereof will be entitled to receive without charge a new Warrant Certificate in respect of the balance of the Common Shares not so purchased. No fractional Common Shares will be issued upon exercise of any Warrant.

This Warrant Certificate evidences Warrants of the Corporation issued or issuable under the provisions of a warrant indenture (which indenture together with all other instruments supplemental or ancillary thereto is herein referred to as the “Warrant Indenture”) dated as of May 15, 2018 between the Corporation and Computershare Trust Company of Canada, as Warrant Agent, to which Warrant Indenture reference is hereby made for particulars of the rights of the holders of Warrants, the Corporation and the Warrant Agent in respect thereof and the terms and conditions on which the Warrants are issued and held, all to the same effect as if the provisions of the Warrant Indenture were herein set forth, to all of which the holder, by acceptance hereof, assents. The Corporation will furnish to the holder, on request and without charge, a copy of the Warrant Indenture.

On presentation at the principal office of the Warrant Agent as set out above, subject to the provisions of the Warrant Indenture and on compliance with the reasonable requirements of the Warrant Agent, one or more Warrant Certificates may be exchanged for one or more Warrant Certificates entitling the holder thereof to purchase in the aggregate an equal number of Common Shares as are purchasable under the Warrant Certificate(s) so exchanged.

The Warrant Indenture contains provisions for the adjustment of the Exercise Price payable for each Common Share upon the exercise of Warrants and the number of Common Shares issuable upon the exercise of Warrants in the events and in the manner set forth therein.

The Warrant Indenture also contains provisions making binding on all holders of Warrants outstanding thereunder resolutions passed at meetings of holders of Warrants held in accordance with the provisions of the Warrant Indenture and instruments in writing signed by holders of Warrants entitled to purchase a specific majority of the Common Shares that can be purchased pursuant to such Warrants.

Pursuant to Section 3.3 of the Warrant Indenture, if at any time following the initial effectiveness of a shelf registration statement filed with the United States Securities and Exchange Commission under the U.S. Securities Act of 1933, as amended, registering the Common Shares issuable upon exercise of the Warrants (a “Registration Statement”) and prior to the Expiry Time, the Corporation determines that no Registration Statement filed with the United States Securities and Exchange Commission is effective, or the use of any such Registration Statement is suspended, the Corporation shall promptly provide written notice of such determination to the Warrant Agent. Upon receipt of such notice, the Warrant Agent shall provide a copy thereof to each Warrantholder, and confirm in writing that the then outstanding Warrants may, until the earlier of (x) a Registration Statement becoming effective or ceasing to be suspended and any prospectus supplement necessary thereto having been filed, or (y) the Expiry Time, if the Current Market Price exceeds the Exercise Price, also be exercised by means of a “cashless exercise” in which the Warrantholder shall be entitled to surrender a Warrant to the Corporation in exchange for the issuance of the number of Common Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where: (a) (A) equals the Current Market Price on the trading day immediately preceding the date of the receipt by the Warrant Agent of the notice of exercise; (b) (B) equals the Exercise Price per Common Share of such Warrant, as adjusted; and (c) (X) equals the number of Common Shares that would otherwise be issuable upon exercise of such Warrant in accordance with its terms by means of a cash exercise rather than a cashless exercise. The issue price for each such Common Share to be issued pursuant to the cashless exercise of a Warrant will be equal to (B), as defined above, and the total issue price for the aggregate number of Common Shares issued pursuant to the cashless exercise of a Warrant will be paid and satisfied in full by the surrender to the Corporation of such Warrant.

A-3

In addition, if the Corporation determines at any time prior to the Expiry Date that U.S. state securities laws are not pre-empted with respect to exercises of the Warrants, the Corporation may by written notice to the Warrant Agent elect to permit exercises of Warrants that are subject to the laws of one or more U.S. jurisdictions to be exercised on a “cashless exercise” basis, pursuant to the cashless exercise formula set forth above. Upon the receipt of such notice, the Warrant Agent shall provide a copy thereof to each Registered Warrantholder, and confirm the Corporation’s determination in writing.

Nothing contained in this Warrant Certificate, the Warrant Indenture or elsewhere shall be construed as conferring upon the holder hereof any right or interest whatsoever as a holder of Common Shares or any other right or interest except as herein and in the Warrant Indenture expressly provided. In the event of any discrepancy between anything contained in this Warrant Certificate and the terms and conditions of the Warrant Indenture, the terms and conditions of the Warrant Indenture shall govern.

Warrants may only be transferred in compliance with the conditions of the Warrant Indenture on the register to be kept by the Warrant Agent in Vancouver, or such other registrar as the Corporation, with the approval of the Warrant Agent, may appoint at such other place or places, if any, as may be designated, upon surrender of this Warrant Certificate to the Warrant Agent or other registrar accompanied by a written instrument of transfer in form and execution satisfactory to the Warrant Agent or other registrar and upon compliance with the conditions prescribed in the Warrant Indenture and with such reasonable requirements as the Warrant Agent or other registrar may prescribe and upon the transfer being duly noted thereon by the Warrant Agent or other registrar. Time is of the essence hereof.

This Warrant Certificate will not be valid for any purpose until it has been countersigned by or on behalf of the Warrant Agent from time to time under the Warrant Indenture.

A-4

The parties hereto have declared that they have required that these presents and all other documents related hereto be in the English language. Les parties aux présentes déclarent qu’elles ont exigé que la présente convention, de même que tous les documents s’y rapportant, soient rédigés en anglais.

Any capitalized term in this Warrant Certificate that is not otherwise defined herein, shall have the meaning ascribed thereto in the Warrant Indenture.

IN WITNESS WHEREOF the Corporation has caused this Warrant Certificate to be duly executed as of ______________________, 20_____
